Kayfun Prime KF6 Tank Review: At the Start of the MTL Revival

 The popularity of small cigarette atomizers seems to be a long way away for old players. I think about how Gobang/Nautilus became popular in the vape circle back then (the main purpose at that time was to replace/quit smoking, not today's smoking). But for most new players (not newbies), large smoke is the mainstream now, and small smoke mouth-type atomizer is like a thing that has been forgotten by people.

  However, the emergence of small cigarette replacement equipment seems to have brought the vape circle back to the old environment of focusing on cigarette replacement and smoking cessation. Small cigarette equipment such as PHIX can indeed better attract smokers to enter the vape circle, both in terms of ease of use and taste, it is relatively mature.   Zipper doesn't know why others have changed, so let's talk about Zipper's own feelings. Zipper still visits a certain treasure from time to time to find some tobacco oil that he is interested in. However, after searching through major stores, he still fails to find the tobacco oil that he is interested in among the dazzling new tobacco oils. In the end, his eyes still stay on Journey/Oak Mountain and other classic old oils.   Coupled with the lack of innovation in most large smoke atomizers now, it is difficult to find something that makes people's eyes shine. The simplicity and convenience of small cigarette replacement equipment can be regarded as one of the biggest inducements. The experience that one tank of oil can smoke for a day also makes it easier for people who are accustomed to carrying a few bottles of oil with them every day for backup. A portable single electric host is enough to support the full day of life of a mouth-smoking atomizer.   All of this made Zipper's eyes turn to the once most popular KF series. He then rummaged through the boxes and found a certain version of KF4, and then compiled a new version of the KF series, KayFun Prime (a certain version). He couldn't wait to see how the KayFun series, the uncrowned king of the mouth-smoking world, has improved and changed their latest products.   Those who are familiar with the KayFun series should know that the KF series often launches a series of accessories (capacity-increasing compartments and various components with different functions). Of course, except for the spare stainless steel oil tank, other components need to be purchased separately.   The KayFun Prime atomizer continues the appearance of the KF V3 MINI and KF V5, and has not changed much on this basis. However, in this era of heavy smoke, the shape of the traditional mouth-sucking RTA atomizer is still quite attractive.   However, compared with the ancient appearance style like a long gun, KayFun Prime still made a certain compromise in appearance, reducing the overall height of the atomizer (the height of the KF5 in the long bin is 76mm, and the height of the short bin is 62mm). It is only 60mm (you can purchase additional height-increasing and capacity-increasing components).   The appearance of the atomization bin and oil guide holes is similar to that of the KF3 MINI. There are six oil guide holes at the bottom. The logo on the outer wall of the atomization bin can also be seen through the glass oil storage compartment.   At the bottom of the atomizer is a gear-type air intake adjusting ring. After lifting the adjusting ring up, you can see six air intake gears opposite to the size of the air intake.   —Detailed explanation of the structure—   Compared with the KF4, which is known as the most complex atomizer, KayFun Prime's structure is not complicated, but its practicality has not been reduced in the slightest, and it has also been optimized in some small details. Let's take a look at it in detail.   The entire atomizer consists of fifteen components: the upper part of the 510-drip nozzle, the lower part of the 510-drip nozzle, the top cover, the oil filling ring, the glass oil bin, the stainless steel oil bin, the atomizing bin, the positive column, the positive column insulating gasket, the negative column and the air intake adjustment base, the air intake channel and the positive column connection component, the insulating ring, the air intake adjustment ring, the air intake size marking base, and the positive screw.   The upper part of the 510 drip nozzle is made of steel, which can effectively avoid heat conduction. Under the connecting thread, it has an inverted conical structure. The inner inclined surface can effectively gather smoke and improve the taste, while the outer inclined surface can be well controlled. Condensate is prevented from being inhaled into the mouth.   The lower part of the 510 drip nozzle is made of stainless steel, and the lower part of the internal connecting thread is provided with a condensate reflux slope to allow the condensate isolated at the upper part to flow back into the atomization chamber. Two rubber rings enable the drip nozzle to be stably placed in the atomizer.   The 510 interface of the top cover is also made with a cold condensate reflux structure. The four external grooves can increase friction. If the top cover is stuck, it is also convenient to open it with tools such as pliers (a wrench is preferred).   The internal multi-layered structures have their own uses, and the grooves on the outer edge can prevent the smoke oil at the oil filling ring from being pressed out after the top cover is completely closed. The connecting threads on the upper part of the rubber ring are open on both sides, which can effectively reduce the excessive pressure in the cabin when the top cover is closed.   The deep groove in the inner ring is used to relieve pressure due to too much smoke oil when the oil passage is opened upside down. If this groove is not designed, when the smoke oil is filled up, there will be not enough air after the atomizer is inverted. The air is discharged by the atomizer, and the inverted smoke oil is pressed into the atomization bin by the bin, resulting in problems such as oil leakage. The rubber ring in the air duct only plays a sealing role, so there is nothing to say.   The top of the oil filling ring is sloped and three low-level oil filling holes make the oil filling operation more convenient. There is no need to worry too much when filling the tobacco oil, which greatly improves the tobacco oil filling speed.   The sealing structure between the oil filling ring and the oil bin adopts a compression seal, so it is better to use some force when locking the oil filling ring to avoid oil leakage caused by insufficient airtightness.   The difference between a glass oil bin and a stainless steel oil bin is that the interior of the stainless steel oil bin has been increased to store more smoke oil (in fact, not much).   The overall height of the atomization bin is 27.4mm, and the bottom is connected to the base with threads. When fully locked, the oil passage can be completely closed to avoid oil leakage caused by bin pressure.   The inner diameter of the atomization chamber is 6.3mm, and the actual atomization space height is about 5mm (manual measurement, there are errors, for reference only!). The top of the atomization bin has an inverted conical gathering structure. The smaller atomization space and the gathering structure at the top can naturally bring a relatively strong taste.   The positive pole, positive pole insulation gasket, negative pole and air intake adjustment base do not need to be disassembled daily, so they are no longer separated and explained. Although the two-sided pole poles are still made of Phillips screws, they have abandoned the form of binding the heating wires with screws. Instead, they adopt the same locking method of combining baffles and screws as the previous generation products. A broken groove is made in the lower part on both sides of the baffle, allowing players to bend in the broken groove when installing thicker heating wires to obtain better coil tightness.   The air inlet has been converted from a traditional circular shape to a straight shape, providing better airflow support for the wider coil and improving the taste performance. There are oil guide cotton placement grooves on both sides of the air inlet hole, which makes it easier to place the oil guide cotton, effectively reducing oil leakage caused by not placing the oil guide cotton well.   A total of four oil inlet holes with a diameter of 1 mm are opened at the bottom of the oil guide cotton, which is enough to ensure the oil guide speed of this small smoke nozzle suction atomizer. However, remember to check whether the oil path is open when using it.   To detach the atomizer base, the positive screw must be removed from the bottom, and then the base bracket and the air intake adjustment ring marked with the air inlet size are removed. After that, you can see a total of 6 air inlet holes with different diameters in a circle around the lower part of the base. The smallest aperture is 0.8mm, and then increments by 0.2mm.   It is worth mentioning that since there is still a certain gap between the intake adjusting ring and the air inlet, which is enough for a small amount of air to circulate, the actual suction resistance is not based on the intake aperture.   Then you can use pliers or socket wrench to rotate the hexagonal bolt at the bottom of the base to remove the air inlet duct and positive column connection assembly. After that, you can see the direction of the intake air flow of this atomizer. After entering the internal space of the base through the external air inlet of the base, it turns into the air inlet port and the air inlet port on the side of the positive column connection assembly (aperture 2.5mm), and is then guided upward, and the air flow is compressed (aperture 1.8mm) to speed up the air flow.   In the center of the bottom of the air inlet and positive pillar connection assembly is the locking screw for the positive bolt. The insulating ring of the air inlet and positive column connection assembly serves to fix the air inlet and positive column connection assembly and prevent it from contacting the outer wall of the negative pole of the atomization chamber and causing a short circuit.   The arc-shaped air inlet on the air inlet adjustment ring itself has a certain air flow compression effect, while the hexagonal opening at the bottom is used to form the air inlet ring limit structure in conjunction with the size of the air inlet marking base.   The interior of the air inlet size indicator base bracket has a circular chamfered structure, which forms a limit structure with the rectangular hole in the lower part of the base. When installing the air inlet size indicator base bracket, remember to install it according to the corresponding hole position.   —Operation and data recommendations—   Before talking about the operation and recommendation data, there is a very important data that needs to be shared with you. The maximum suction resistance of this atomizer (i.e., the minimum gear) is equivalent to the minimum suction resistance of gobang (i.e., after removing the intake screw). The suction resistance at the largest gear is still relatively difficult to breathe lightly, but the change in the taste of mouth inhalation is still relatively manageable.   For KayFun Prime, there are still many heating wire materials and wire diameters that can be used. You can choose A1 heating wire with a strong taste, or you can choose temperature-controlled heating wire with a clear taste. Of course, single-core Clapton and twisted wire are also optional types. (SS316 heating wire can well exert the effect of nicotine in tobacco oil when controlling temperature, making it feel like hitting the throat)   Let's talk about the installation operation of this atomizer when using ordinary power wire/temperature control wire/fancy heating wire:   1. Power wire (ordinary coil):   It is recommended to use Cantel A1 heating wire. Due to the good oil guiding performance and variability of air intake volume of this atomizer, the wire diameter of the heating wire can be selected between 0.32/0.4/0.5.   The ring diameter of 2.5mm, which is commonly used in mouth-suction atomizers, is still recommended. This ring diameter can not only ensure good air flow to wrap the coil, but also provide enough oil conducting cotton to avoid oil leakage caused by too little oil conducting cotton.   When using a thread diameter of 0.32, there is no need to bend the line foot to strengthen the fixation. When using a thread diameter of 0.4 and above, it is best to bend the line foot into the locking wire groove to enhance the resistance of the screw to the line foot.   The recommended data is 0.32 (7 - 8 cycles)/0.4 (6 - 7 cycles)/0.5 (6 - 7 cycles).   After installing the coil and burning the wire, it is time to install the oil conducting cotton. There is a very metaphysical problem here. After testing the zipper, it was found that using the cotton rolling method will achieve a better taste and use time (for personal opinion only, no theoretical basis), you may wish to give it a try. After installing the atomizer and filling it with tobacco oil, you can smoke happily all day.   2. Temperature control wire (ni 200, ss 316/304)……   The data of the temperature control wire is not much different from that of the power wire. However, since the loose winding mode is recommended, the number of turns is reduced by 1 - 2 turns accordingly. Loose winding coils may not be familiar to novices who have entered the pit recently. In fact, the production method is not complicated (often novices feel that loose winding is used when winding the wire). After making a dense winding coil, put the coil on the winding rod, stretch it to both sides, and then press it to the middle. The coil will naturally form a loose winding coil with uniform gaps due to the elasticity of the metal.   Note: There is no contact between loosely wound coils, so there will be no uneven heating. Ni200 material may even produce toxicity at high temperatures, so wire burning is not recommended.   Extra attention needs to be paid when installing the oil guide cotton for loosely wound coils to avoid situations such as distorting the coil belt when installing the oil guide cotton.   3. Fancy heating wire (single-core Clapton/twisted wire)   The choice of fancy heating wire only needs to pay attention to the wire diameter not exceeding the diameter of the wire locking groove. After all, a thicker wire diameter requires more contact area to obtain better firmness. In addition, attention should also be paid to the coil width. After all, the width of the air inlet is limited, so it is only necessary to ensure that the coil width is close to the length of the air inlet.   —precautions for use—   Due to the air intake structure in the base, condensate will be deposited in the air intake space in the base after long-term use, which will affect the suction experience (increased suction resistance, grunt during suction, etc.). At this time, disassemble and wipe it.   (The oil path is open on the left side, and the oil path is closed on the right side)   Try to get into the habit of rotating the oil storage tank to close the oil passage before filling it, and turning it upside down to open the oil passage. Otherwise, it will be difficult to clean up the smoke oil after being pressed into the air inlet by the tank, and it will also avoid leaking oil from the air inlet hole (Don't forget to open the oil passage when pumping).   Do not use an oversized screwdriver when locking the heating wire to avoid excessive torque to twist the screw or screw the atomizer to slip the wire.   —summary and outlook—   As the wave of smoke gradually subsided, the recovery of small cigarettes seems to be in the bud. Looking back on the past, the trend of e-cigarettes seemed to be like a cycle of four seasons. From taste to smoke, it gradually returned to taste. Every cycle, it will always inject different vitality and bring new technological and structural changes.   The protagonist of this cycle seems to be a small-cigarette-type cigarette replacement device, which is convenient and concise, and has high acceptance by smokers. It will not be embarrassing to use it on various occasions. But who can tell for sure how the future will develop? Small smoke atomizers may also stand at the top of the trend again through a certain technological breakthrough, right?   Kf took a detour when the smoke rose. It wanted to maintain its own taste and be compatible with the smoke. All of this created the KF5, an RTA atomizer that prefers light lung inhalation. Now, the birth of KayFun Prime has brought the taste of small cigarettes back on track and returned to the familiar smoking mode.   There is no doubt that KF6 has a very good mouth-sucking taste, and is also very good in terms of oil conductivity and coil installation convenience. However, friends who want to start should remember that this is a mouth-sucking atomizer, which is now a support for high-VG cigarette oil on the market is very unfriendly. It is not just a matter of oil conductivity, but it is difficult to restore the taste of high-VG cigarette oil itself.   So everyone should try to use cigarette oil with a vgpg ratio of 5:5, and the nicotine content is above 6 mg (the zipper has been increased to 12 mg +), so that the taste and throat touch of the cigarette oil can be guaranteed (the combination of high pg and high nicotine can make the mouth-inhalation atomizer have a good taste, which is what people often say is that there is no feeling when smoking).# p #pagination title #e #
