Description

Technical Field

[0001] The present invention relates to an atomizer, a smoke oil cartridge and an electronic cigarette, and in particular to an electronic cigarette with high smoke output efficiency, smooth ventilation channel and stable smoke output. Background Art

[0002] At present, electronic cigarettes are generally divided into smoke oil type and tobacco type. The tobacco type electronic cigarette includes a power supply host, a heater and an upper cover. The upper cover is used to hold the cartridge accommodating cavity of the tobacco type cigarette cartridge. The upper cover is installed on the power supply host. The heating element of the heater passes through the bottom wall of the upper cover and extends into the cartridge accommodating cavity of the upper cover. When in use, the user inserts the cigarette cartridge into the cartridge accommodating cavity, inserts the heating element into the cigarette cartridge, turns on the power supply host to heat the heating element, so that the tobacco in the cigarette cartridge is heated without burning and is available for the user to inhale. After use, pull out the cigarette cartridge and discard it. The upper end of the cigarette cartridge is formed with a suction nozzle that imitates real cigarettes, which has a good user experience and is easy to replace. However, tobacco electronic cigarettes are prone to burn tobacco and produce a burnt smell, which affects the experience, and the types of tobacco are limited and the flavors are limited.

[0003] E-cigarettes with oil generally include an oil tank for oil, an atomizer, and a battery. When used by a user, the atomizer obtains the oil in the oil tank through an oil-conducting medium and heats the oil into mist to simulate the feeling of real smoke. A large amount of oil is stored in the oil tank. In order to prevent the oil from entering the mouthpiece, a sufficient isolation zone is set between the smoke duct of the mouthpiece and the oil tank. Since consumers need to use it multiple times, the mouthpiece is often set as a plastic part with a hollow hole, which has a poor experience and is inconvenient to replace the oil tank.

[0004] To this end, in Chinese patent CN201610806671, an eddy current heated electronic cigarette and atomizer are disclosed, wherein the atomizer includes a shell forming a cavity, an induction coil arranged in the shell, and a smoke oil cartridge inserted in the cavity, wherein an electromagnetic induction heating body and a cavity for holding smoke oil are arranged in the smoke oil cartridge, and the electromagnetic induction heating body can generate corresponding eddy currents under the magnetic field generated by the induction coil, thereby heating the atomized smoke oil, and a filter device is arranged at the front end of the smoke oil cartridge to filter the smoke generated by the atomizer. This technology not only makes it easy to plug the smoke oil cartridge into the shell and replace the smoke oil cartridge, but also uses the shell wrapped with the filter device as a cigarette holder to imitate real cigarettes, and the user experience is good.

[0005] However, in this type of atomizer, in order to reduce the volume, the electromagnetic induction heating body is directly immersed in the smoke oil and is simply isolated by a layer of oil-conducting layer. The smoke oil can easily overflow from the electromagnetic induction heating body into the gas channel during long-term transportation and storage, and then gradually diffuse to the filter device of the cigarette holder, or overflow from the bottom of the gas channel, causing the smoke oil cartridge to leak, resulting in a poor user experience. The shell that forms the cavity must be made of a sufficiently hard material to prevent consumers from bending or pinching it during use, causing a large amount of smoke oil to leak out. Moreover, when in use, the electromagnetic induction heating body directly heats the saturated smoke oil, which requires a long time to heat to produce smoke, and the water content (liquid oil) of the generated smoke is too heavy, resulting in a poor user experience.

[0006] Therefore, there is an urgent need for an electronic cigarette atomizer and an electronic cigarette that can solve the above problems. Summary of the invention

On the other hand, the smoke oil is bound to the oil storage member and forms an atomization bin for installing the electromagnetic induction member, so there is no need to set up a separate atomization bin, the structure is simple, the volume is small, and the electromagnetic induction member is installed in the hollow cavity of the oil storage member, and the ventilation channel is directly connected to the hollow cavity, so that when consumers use it, the ventilation is smooth and the smoke is easy to conduct out.

[0067] refer to Figure 1a , an atomization bin 31 is formed in the atomization area 102, and the oil storage atomizer 30 includes the atomization bin 31, an oil storage part 33 for storing tobacco oil, and an atomization structure. The oil storage part 33 is in a hollow tubular shape and is installed in the atomization bin 31. The oil storage part 33 is made of oil storage material and is used to store tobacco oil. A hollow cavity 330 is formed in the middle of the oil storage part 33 and runs through the axial direction. The atomization structure includes an electromagnetic induction part 32, and a ventilation channel connecting the electromagnetic induction part 32 and the hollow cavity 330. The electromagnetic induction part is installed in the hollow cavity 330. In this embodiment, a ventilation channel 301 is formed between the electromagnetic induction part 32 and the hollow cavity 330. The tobacco oil in the atomization bin 31 is stored in the oil storage part 33, and the electromagnetic induction part 32 can heat the tobacco oil in the oil storage part 33. The hollow cavity 330 is disposed along the longitudinal direction of the strip-shaped housing 10 to communicate with the smoke filter portion 20 and the vent hole 41 of the sealing plug 40 .

The airflow can enter the hollow cavity 330 from the ventilation hole 41 of the sealing plug 40, gradually flow from the lower end to the upper end of the hollow cavity, and transport the generated smoke at the ventilation channel 301 and from the upper end of the hollow cavity 330 to the smoke filter 20.

[0069] The smoke oil is not freely contained in the atomization chamber 31 in liquid form, but is bounded inside by the oil storage part 33, forming an oil storage part in a solid form, which can not only effectively prevent the smoke oil from leaking out of the electromagnetic induction part 32, but also ensure that when the electromagnetic induction part 32 heats the smoke oil, the smoke oil it contacts will not be too saturated to affect the smoke output speed and efficiency. The smoke output speed is fast, the efficiency is high, and the generated smoke is more evenly vaporized.

[0070] In this embodiment, the outer diameter of the oil storage member 33 is interference fit with the inner diameter of the atomization chamber 31 , so that the oil storage member 33 is embedded in the atomization chamber 31 .

[0071] In this embodiment, the oil storage member 33 is a sponge structure. Specifically, the oil storage member is a sponge structure made of fiber cotton. Of course, the oil storage member can also be a sponge structure made of other oil storage materials. The oil storage member 33 is not limited to a sponge structure, and can also be a porous structure with gaps formed by pressing fiber oil storage materials.

[0072] The oil storage part 33 is a sponge structure formed by bonding fiber cotton and plastic polymer. The oil storage capacity of the oil storage part 33 is greater than or equal to 50% and less than or equal to 90%, which effectively prevents the oil from overflowing. The oil storage capacity is the ratio of the volume of the oil to the volume of the oil storage part. The thickness of the oil storage part 33 is greater than or equal to 1mm and less than or equal to 2mm, which is convenient for oil storage. Of course, the thickness of the oil storage part 33 is not limited to this, and can be set according to the actual size and needs of the atomization bin, and can also be greater than or equal to 2mm.

Of course, the electromagnetic induction component 32 can also directly contact the oil storage component 33, and in this case, the oil storage component 33 needs to have a certain heat resistance.

[0075] In this embodiment, the first oil absorbing medium 34 is organic cotton. The oil storage capacity (oil storage per unit volume) of the first oil absorbing medium 34 is lower than the oil storage capacity of the oil storage member 33, and the oil absorption capacity of the first oil absorbing medium 34 is greater than the oil absorption capacity of the oil storage member 33. Of course, the first oil absorbing medium 34 can also be wood fiber or bamboo fiber. The oil absorption capacity is the speed at which the same volume of the medium absorbs the smoke oil.

[0076] refer to Figure 1a and Figure 2 The first oil absorbing medium 34 is an oil absorbing rope and is wound around the electromagnetic induction member 32 at a certain interval, and a spiral ventilation channel 302 is formed between adjacent oil absorbing ropes.

[0077] In this embodiment, the electromagnetic induction component 32 is a straight electromagnetic induction sheet, which is a metal sheet. Of course, the electromagnetic induction component 32 may also be other structures and is not limited to this embodiment.

[0078] Among them, the maximum distance of the outer periphery of the atomizing structure needs to match the inner diameter of the hollow cavity 330, so that the atomizing structure can be installed in the hollow cavity 330, and the minimum distance of the outer periphery of the atomizing structure is smaller than the inner diameter of the corresponding position of the hollow cavity 330, which is smaller than the preset length, so that there is a certain gap between the atomizing structure and the hollow cavity 330 to form the ventilation channel 301. Based on this embodiment, when the cross-section of the hollow cavity 330 is circular, the cross-section of the electromagnetic induction component 32 is non-circular, such as a rectangle, polygon, triangle, fan-shaped, elliptical, a strip with a concave groove, etc. In this embodiment, the electromagnetic induction component 32 is preferably flat.

[0079] The strip-shaped shell 10 is in the shape of a cigarette-like strip, and is made of plastic or waterproof paper. The strip-shaped shell 10 is also wrapped with a paper layer 50. The paper layer may be printed with a corresponding stripe pattern.

[0082] Preferably, the electromagnetic induction element 32 is spaced a certain distance from the front end and the rear end of the atomization chamber 31 to prevent the electromagnetic induction element 32 from burning the partition 103 or other parts of the strip-shaped housing 10 .

[0083] The better, reference Figure 1b Different from the first embodiment, in the second embodiment of the present invention, there is a certain distance between the oil storage member 33 and the front end of the atomization bin 31 to form a cooling zone 105, and a cooling member 60 is installed in the cooling zone 105. The cooling member 60 is provided with a vent hole 61 extending along its axial direction and communicating with the ventilation channel 301.

The ventilation channel 321 is communicated with the hollow cavity 301.

[0085] refer to Figure 5 The ventilation channel 321 is connected to the atomization bin 31 from the side of the electromagnetic induction component 32 .

[0086] refer to Figure 5 and Figure 6a The electromagnetic induction component 32a is in a laterally closed ring shape, and a plurality of through holes 322 are provided on the annular side wall of the electromagnetic induction component 32a. The first oil absorption medium 34a is connected to the ventilation channel 321 through the through holes 322. When working, the electromagnetic induction component 32a heats the smoke oil on the first oil absorption medium 34a to generate smoke. The smoke passes through the through holes 322 and enters the ventilation channel 321, and enters the smoke filter 20 along the ventilation channel and is sucked out.

[0087] In this embodiment, the electromagnetic induction member 32a is a tubular object with a circular cross section. Of course, the cross section of the electromagnetic induction member 32a can also be a circular ring in a polygonal, semicircular, elliptical or other shapes.
