Description

Induction heating cigarette-type electronic cigarette heating apparatus {Induction heating cigarette-type electronic cigarette heating apparatus}

The present invention relates to an induction heating type cigarette type electronic cigarette heating device that can generate vapor by heating an electronic cigarette stick by induction heating.

In general, a cigarette-type electronic cigarette heating device is a device that generates vapor by heating the tobacco leaves of an electronic cigarette stick through a blade that generates heat while operating with battery power.

Unlike tobacco cigarettes, which heat tobacco leaves directly with a flame, these cigarette-type electronic cigarette heating devices indirectly heat the tobacco leaves of the electronic cigarette stick through the blade, generating almost no tar and carbon monoxide and eliminating the smell of burning tobacco leaves. It has the advantage of being almost non-existent.

However, as the cigarette-type electronic cigarette heating device is used with the electronic cigarette stick inserted into the blade with the bottom open, the bottom of the electronic cigarette stick is heated after use, causing the remaining cigarette ash to remain on the surface of the blade or the electronic cigarette stick to become damaged. It remains in the insertion space where it is inserted.

In other words, the cigarette-type electronic cigarette heating device has a problem in that it is inconvenient to use because the cigarette ash of the electronic cigarette stick sticks to the surface of the blade or remains in the insertion space after use, and the user must periodically remove it.

In addition, if this work is not done regularly and cigarette ash adheres to the surface of the blade, the service life of the blade is greatly shortened and it must be replaced frequently, which increases the cost burden.

In addition, when using a blade with tobacco ash stuck to the surface, the electrical resistance of the blade increases due to the cigarette ash, which causes excessive current to be applied to the blade and causes the blade to heat up above the set temperature. This causes the tobacco leaf to burn and lose flavor.

Therefore, research and development is needed to improve the structure of cigarette-type electronic cigarette heating devices to prevent internal sticking and remaining of cigarette ash, increase convenience of use, avoid excessive cost burden, and maintain the flavor of cigarettes.

Next, the stick holder 50 is installed in the first installation space 21 of the frame 20 to maintain the electronic cigarette stick (S) with the conductor plate (M) embedded in the center inserted vertically up and down. It can be very fixed.

To this end, the stick holder 50 has a shape corresponding to the first installation space 21 of the frame 20, as shown in FIG. 3, and has an upper insertion hole 511 on one side into which the electronic cigarette stick (S) is inserted. The connection flange 51 is formed to penetrate vertically up and down, and the lower insertion hole 521 is formed to extend vertically on one lower side of the connection flange 51 and the electronic cigarette stick (S) is inserted, and the upper insertion hole 511 ) It may be composed of a cylindrical holder tube 52 extending correspondingly, and a holder cover 53 installed at the lower part of the cylindrical holder tube 52 to close the lower part of the lower insertion hole 521.

Therefore, in the stick holder 50, a certain portion of the lower portion of the electronic cigarette stick (S) is inserted vertically up and down through the upper insertion hole 511 of the connection flange 51 and the lower insertion hole 521 of the cylindrical holder tube 52. make it possible Additionally, the stick holder 50 can provide a space where the induction heating means 80 can be installed through the outer peripheral surface of the cylindrical holder tube 52.

That is, the stick holder 50 presses the outer peripheral surface of the electronic cigarette stick (S) inserted into the upper insertion hole 511 and the lower insertion hole 521 through the upper pressing protrusion 512 and the lower pressing protrusion 522. By compressing, the electronic cigarette stick (S) can be fixed and supported so that it does not move.

And the stick holder 50 holds the electronic cigarette stick (S) as the lower surface of the electronic cigarette stick (S) inserted into the upper insertion hole 511 and the lower insertion hole 521 is seated on the seating protrusion 523. It can be guided to always be inserted at a certain length.

Therefore, as shown in Figure 5, the stick holder 50 can not only guide the insertion length of the electronic cigarette stick (S) to be constant, but also support the electronic cigarette stick (S) so that it does not move, so that the electronic cigarette stick (S) can be fixed. (S) can be heated by the induction heating means (80) at the same location at all times without flow.

Meanwhile, as shown in FIG. 4, the stick holder 50 has an upper insertion guide surface 512a formed at the top of the upper pressing protrusion 512 and consisting of an inclined surface whose protrusion length gradually becomes shorter as it goes downward, and a lower pressing protrusion. A lower insertion guide surface 522a formed at the top of 522 and composed of an inclined surface whose protrusion length gradually becomes shorter as it goes downward may be further included.

The electronic cigarette stick (S) can be heated to a set temperature.

Therefore, the induction heating means 80 can uniformly heat the electronic cigarette stick (S), which is inserted at a predetermined position through the stick holder 30 for a certain insertion length and supported without movement, to a constant temperature, so that the electronic cigarette stick (S) ), the flavor of the electronic cigarette stick (S) can be maintained consistently without causing any burning odor.

In addition, the induction heating means 80 includes a first insulating film 82, an insulating tape 83, a second insulating film 84, an insulating fabric 85, and an insulating film 86 on the outer peripheral surface of the induction coil 81. By being covered sequentially to form multiple layers, not only can the external outflow of electrical resistance heat be minimized, but also the external outflow of high-frequency current flowing in the induction coil 81 can be effectively blocked.

Meanwhile, on one side of the cylindrical holder tube 52, a terminal fixture 54 is installed with a pair of mounting grooves 541 spaced apart from each other so that one terminal and the other terminal of the induction coil 81 can be inserted and mounted, respectively. It can be.

That is, when one terminal and the other terminal of the induction coil 81 are electrically connected to the circuit board 30 through the stick holder 50, they are maintained spaced apart from each other by the terminal holder 54, so that they contact each other and short circuit. You can prevent the negative effects that occur.

Additionally, an insulating coating layer 55 may be formed on the lower surface of the holder cover 53 by applying and hardening an insulating resin.

Therefore, the insulation performance can be further strengthened by the insulation coating layer 55 blocking the electrical resistance heat from leaking to the outside through the gap between the cylindrical holder tube 52 and the holder cover 53.
