Technical Field

[0001] The utility model belongs to the technical field of electronic cigarettes, and particularly relates to an electronic cigarette with a mesh heating element. Background Art

[0002] An electronic cigarette is an electronic product that imitates a cigarette. It generates smoke by non-combustion heating of e-liquid containing components such as nicotine for users to inhale. This non-combustion heating avoids harmful substances such as tar generated during cigarette combustion and can bring a smoking-like feeling to users. In recent years, it has become increasingly popular among consumers.

[0003] At present, most of the electronic cigarettes on the market heat the e-liquid adsorbed on the oil-guiding porous fibrous material through a heating device to achieve atomization of the e-liquid. Generally, cotton is used as the oil-guiding material, and the heating device is a heating wire. The heating wire is wound around the cotton. However, when the suction frequency is too fast, the heating of the cotton by the heating wire is uneven, or the cotton adsorbs insufficient e-liquid, the temperature of the cotton is too high, burning the cotton and resulting in a burnt smell, reducing the user experience and being unfavorable for product sales. Therefore, an electronic cigarette with a mesh heating element is needed to solve the above problems. Summary of the Invention

[0004] Aiming at the technical problems in the prior art that the heating of cotton by the heating wire is uneven and the insufficient adsorption of e-liquid by the cotton leads to too high a temperature of the cotton, burning the cotton and resulting in a burnt smell, the utility model provides an electronic cigarette with a mesh heating element.

[0005] To achieve the above object, the utility model provides an electronic cigarette with a mesh heating element, including a cigarette rod and a cartridge. A battery is provided in the cigarette rod, and a liquid storage chamber for storing e-liquid is provided in the cartridge. The cigarette rod and the cartridge are detachably connected. It is characterized in that a mesh heating part with several through holes is further provided in the cartridge. A ceramic body is closely attached to the inside of the mesh heating part.

[0006] Preferably, the liquid storage chamber is arranged at one end of the cartridge far from the cigarette rod, and the mesh heating part is arranged at one end of the cartridge close to the cigarette rod. A silica gel sealing sleeve for isolating e-liquid is provided between the liquid storage chamber and the mesh heating part.

[0007] Preferably, the silica gel sealing sleeve is sleeved on the mesh heating part. The silica gel sealing sleeve is closely attached to the inner wall of the cartridge. Several anti-slip rings for increasing friction are provided on the surface of the silica gel sealing sleeve to fix the position of the mesh heating part. Among them, one side of the silica gel sealing sleeve close to the cigarette rod is an open structure.

[0008] Preferably, at least one oil guiding channel is provided through the silica gel sealing sleeve, so that the e-liquid flows from the liquid storage chamber into the mesh heating part.

[0009] Preferably, the cartridge further includes a base, and the base is provided with two electrode posts, and the bottom ends of the two electrode posts are respectively electrically connected to the positive and negative electrodes of the battery in the cigarette rod.

[0020] To describe the present invention more clearly, the present invention will be further described below with reference to the accompanying drawings.

[0021] In the following description, specific details are given to provide a deeper understanding of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. It should be understood that the specific embodiments are only used to explain the present invention and are not used to limit the present invention.

[0022] It should be understood that when the terms "comprise" and / or "include" are used in this specification, they indicate the presence of the described features, wholes, steps, operations, elements or components, but do not exclude the presence or addition of one or more other features, wholes, steps, operations, elements, components or their combinations.

[0023] Please refer to Figures 1-3 , this utility model includes a cigarette rod 2 and a cartridge 1. A battery is provided in the cigarette rod 2, a liquid storage chamber 11 for storing e-liquid is provided in the cartridge 1, and a mesh heating part 12 with a number of through holes 122 is also provided in the cartridge 1. A ceramic body 13 is attached inside the mesh heating part 12. A number of micropores are provided on the surface of the ceramic body 13 so that the ceramic body 13 can adsorb e-liquid. The e-liquid is adsorbed by the ceramic body inside through the through holes of the mesh heating part.

[0024] Then the mesh heating part heats the e-liquid adsorbed on the ceramic body. Among them, the through holes on the mesh heating part can adjust the distribution of resistance so that the heating of the heating part is uniform. In this way, there is no need to use oil guiding parts such as cotton, avoiding the technical problem of cotton burning and generating a burnt smell.

[0025] In a specific embodiment, the mesh heating part is made of at least one resistance material such as tungsten, molybdenum, manganese and other metals or nickel alloys and chromium alloys. The resistance material is printed on the ceramic body, and then a ceramic heating body is formed by co-sintering the ceramic and the metal. It has the advantages of corrosion resistance, high temperature resistance, long service life, high energy efficiency, uniform temperature, good thermal conductivity, fast thermal compensation speed, etc., and does not contain harmful substances such as lead and mercury, meeting the environmental protection requirements.

[0026] Please refer to Figure 4 , in this embodiment, the mesh heating part is grid-shaped. In specific production, the grid size of the mesh heating part is adjusted according to different e-liquids to achieve the best taste of the e-liquid.

[0027] Please refer to Figure 2 、Figure 3 and Figure 5 , the liquid storage chamber 11 is arranged at one end of the original cigarette rod 2 in the cartridge 1, and the mesh heating part 12 is arranged at one end of the cartridge 1 close to the cigarette rod 2. A silica gel sealing sleeve 14 is arranged between the liquid storage chamber 11 and the mesh heating part 12 to prevent the e-liquid from coming into large-area contact with the mesh heating part. When the mesh heating part starts to heat, if there is contact between the heating part and the e-liquid, it will cause the e-liquid in the e-liquid chamber to boil violently, increasing the pressure in the chamber and posing a safety hazard. Therefore, an isolation device needs to be arranged between the heating part and the e-liquid. Generally, a plastic spacer or a baffle made of other heat-insulating materials can be arranged;

[0028] In the present utility model, a silica gel sealing ring is used as the isolation device. The silica gel sealing sleeve 14 is sleeved on the mesh heating part 12. The silica gel sealing sleeve 14 is closely attached to the inner wall of the cartridge 1, and a plurality of anti-slip rings 142 are arranged on the surface of the silica gel sealing sleeve to increase the friction force between the silica gel sealing sleeve 12 and the inner wall of the cartridge 1, so as to fix the position of the mesh heating part 12 well. Among them, one side of the silica gel sealing sleeve 14 close to the cigarette rod 2 is an open structure to expose the mesh heating part for connecting the power supply. Obviously, the present utility model uses the silica gel sealing ring to not only isolate the e-liquid and the heating part, but also fix the position of the heating part. And because of its elasticity, the requirement for the dimensional accuracy of the heating part is not high, which is convenient for mass production.

[0029] Please refer to Figure 2 and Figure 3 , in this embodiment, at least one oil guiding channel 141 is arranged through the silica gel sealing sleeve 14 so that the e-liquid flows from the liquid storage chamber into the mesh heating part. The number of oil guiding channels can be adjusted according to the actual situation, so that when the e-liquid enters the heating part, it can maintain an appropriate flow rate, so as not to cause the heating part to dry burn due to too little e-liquid or the smoke to become thick due to too much e-liquid, which affects the taste.

[0030] Please refer to Figure 2 , the cartridge 1 further includes a base 15. The base 15 is provided with two electrode posts 151. The bottom ends of the two electrode posts 151 are respectively electrically connected to the positive and negative electrodes of the battery in the cigarette rod 2. The two ends of the side of the mesh heating part 12 close to the base 15 are respectively provided with end electrodes 121. The end electrodes 121 at both ends are respectively electrically connected to the top ends of the two electrode posts to form a current path. In a specific embodiment, the electrode posts generally adopt spring top pins, and their stable contact resistance ensures the stability of the electronic cigarette and can better adapt to the change of the position of the heating part. In addition, a coating can be added outside the top pins to reduce the chemical influence of the smoke on the components.

[0031] The connection between the cartridge and the cigarette rod of the electronic cigarette is detachable, and generally, structures such as buckles or fitting posts and fitting grooves can be arranged to achieve this.

[0032] In this embodiment, please refer to Figure 2 , the base 15 further includes at least one magnetic member 152. A metal member is correspondingly provided at one end of the cigarette rod close to the cartridge for the detachable connection between the cartridge and the cigarette rod. The magnetic member is less likely to be damaged compared with the connection of the above mechanical structure and has a long service life.

[0033] The advantages of the present utility model are as follows:

[0034] 1) A mesh heating part is provided to heat the e-liquid and the ceramic body adsorbs the e-liquid, so that the heating device generates heat evenly, the components of the aroma will be more balanced, the taste will be better, and it is avoided that the local temperature is too high, resulting in the decomposition of the e-liquid in this part to produce harmful substances, and it is also avoided to use fiber oil guiding members such as cotton, which will cause the cotton to be burned and produce a burnt smell when the temperature is too high or the amount of adsorbed e-liquid is insufficient, affecting the user experience.

[0035] 2) A silica gel sealing ring is arranged between the heating part and the e-liquid, which can not only prevent the e-liquid from directly contacting the heating part and causing boiling, but also fix the position of the heating part. The structure is simple and is beneficial to the industrial production of the electronic cigarette.

[0036] The above only discloses several specific embodiments of the present utility model, but the present utility model is not limited thereto. Any changes that can be thought of by those skilled in the art should fall within the protection scope of the present utility model.
