Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heating and electronic cigarettes, and in particular to a heating film electronic cigarette. Background Art
[0002] Electronic cigarettes, also known as virtual cigarettes or e-cigarettes, look like cigarettes and have a flavor similar to cigarettes, even offering many more flavors than regular cigarettes. They also deliver smoke and flavors just like cigarettes. They are primarily used for smoking cessation and as a cigarette replacement. They are a non-combustion alternative to tobacco. They share some characteristics with regular cigarettes, offering a boost of energy and satisfying the pleasure smokers develop over years of habit. However, they are fundamentally different from regular cigarettes. They do not burn, contain tar, or produce the over 460 chemicals that can cause respiratory and cardiovascular diseases when regular cigarettes are burned. Thus, they eliminate the carcinogens found in regular cigarettes and prevent the harmful effects of "secondhand smoke" on others or the environmental impact.
[0003] An electronic cigarette typically consists of a cigarette holder, a mouthpiece, a smoke chamber within the holder, and a smoke cartridge within the chamber. The cartridge also contains an atomizer, which generates heat and vaporizes the smoke cartridge. The cartridge also contains smoke liquid, simulating the effects of a cigarette.
[0004] Among them, a heating structure is also provided in the smoke chamber. The heating structure of the electronic cigarette in the prior art has two structures: one is that a needle-shaped heating element is provided at the bottom of the smoke chamber. When the cigarette cartridge is placed in the smoke chamber and pressed downward, the needle-shaped heating element will pass through the cigarette cartridge, and then the heat will be directly transferred to the cigarette cartridge through the needle-shaped heating element, causing it to undergo a chemical reaction and produce smoke. The other is that the outer wall of the smoke chamber is fixedly covered with a heating film. The cigarette cartridge is placed in the smoke chamber, and the heat is generated by the heating film on the outer wall, and then the heat is transferred to the cigarette cartridge through the smoke chamber wall, causing it to undergo a chemical reaction and produce smoke. Electronic cigarettes with these two heating structures in the prior art, because the cigarette cartridge generates some chemical substances when it is heated and undergoes a chemical reaction, it will remain in the smoke chamber. When the residue accumulates more and more, it will affect the heat conduction and heating effect of the smoke chamber, resulting in the smoke chamber generally needing to be completely replaced after 3-5 months of use. The price of the smoke chamber is relatively expensive, generally 150-200 yuan each. Therefore, the electronic cigarettes in the prior art have the defects of a short smoke chamber service life and a relatively high cost of use. Utility Model Content
[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a heating film electronic cigarette, which can avoid replacing the entire cigarette chamber and has the advantages of long cigarette chamber service life and low use cost.
[0006] In order to achieve the purpose of the above utility model, the technical solution adopted by the utility model is as follows:
[0007] The utility model provides a heating film electronic cigarette, comprising a cigarette rod, a cigarette cavity arranged in the cigarette rod, a heating film tube sleeved on the inner wall of the cigarette cavity and formed by rolling a heating film, and a cigarette cartridge inserted into the tube cavity of the heating film tube.
[0008] The utility model relates to a heating film electronic cigarette. Since a heating film tube is sheathed on the inner wall of the smoke chamber as the heating structure of the electronic cigarette, the heating film tube is directly inserted into the smoke chamber during installation. When the heating film tube needs to be replaced, it can be directly pulled out. It has the advantages of simple structure and easy installation and disassembly. In addition, the cigarette cartridge is inserted into the tube cavity of the heating film tube, so it can prevent the chemical substances generated by the chemical reaction of the cigarette cartridge from being directly deposited on the surrounding wall of the smoke chamber. The generated chemical substances adhere to the tube wall of the heating film tube. After a period of use, when the heating film tube is attached to a large amount of chemical substances and affects the heating and heat transfer of the heating film tube, the heating film tube can be directly pulled out and replaced. Since the production cost of the heating film tube is relatively low, generally 0.5 yuan to 1 yuan per piece, compared with the electronic cigarettes of the prior art that often replace the entire smoke chamber, the present application can avoid replacing the entire smoke chamber, extend the service life of the smoke chamber, and greatly reduce the cost of using the electronic cigarette.
[0009] Furthermore, the heating film tube is an integrally formed, rolled and closed heating film tube; this structure has the characteristic of simple preparation. In addition, the closed heating film tube can better prevent the chemical substances generated during the chemical reaction of the cigarette cartridge from adhering to the surrounding wall of the cigarette cavity, which can better extend the service life of the cigarette cavity and reduce the use cost of the electronic cigarette.
[0010] Alternatively, the heating film tube is a heating film tube that is rolled and not closed. This structure has the advantages of being simpler to manufacture and having lower production costs. Even if the heating film tube is not closed, the gap is very small, which can effectively prevent the chemical substances generated by the chemical reaction of the cigarette cartridge from adhering to the surrounding walls of the smoke chamber, thereby effectively extending the service life of the smoke chamber and reducing the cost of using the electronic cigarette.
[0011] Furthermore, electrodes are provided at both ends of the heating film tube, and the electrodes are connected to wires for electrical connection to a power source. When the wires connected to the electrodes are connected to a power source, current flows through the wires into the electrodes at both ends of the heating film tube, and then flows through the electrodes into the conductive heating layer of the heating film tube, causing the heating film tube to heat up due to the inflow of current, thereby heating the cigarette cartridge.
[0012] Furthermore, a clamping block is provided on the bottom wall of the smoke chamber, and a clamping groove for fixing the heating film tube is formed between the clamping block and the side wall of the smoke chamber. During installation, when the heating film tube is inserted into the smoke chamber, it is inserted until it reaches the clamping groove formed between the clamping block and the side wall of the smoke chamber, which enables the clamping block to clamp and fix the heating film tube, preventing the heating film tube from loosening and affecting the use of the electronic cigarette.
[0013] Furthermore, the bottom wall of the smoke chamber is provided with a clamping block on both sides; a clamping groove is formed between each clamping block and the side wall of the smoke chamber. By providing clamping blocks on both sides of the bottom wall of the smoke chamber, the heating film tube can be better fixed and stabilized.
[0014] Furthermore, two clamping blocks are provided on both sides of the bottom wall of the smoke chamber; a clamping groove is formed between each clamping block and the side wall of the smoke chamber. By providing two clamping blocks on both sides of the bottom wall of the smoke chamber, the heating film tube can be better fixed and stabilized.
[0015] Furthermore, the clamping block is configured as a rectangular block. When the heating film tube is in a rectangular shape, the clamping block is correspondingly configured as a rectangular block, which can better clamp and fix the heating film tube.
[0016] Furthermore, the heating film electronic cigarette further comprises an annular limiting sleeve for attaching the heating film tube to the inner wall of the cigarette chamber; an annular limiting groove is formed on one side of the limiting sleeve;
[0017] The limiting sleeve is sleeved with one end of the opening of the smoke chamber.
[0018] Among them, after the heating film tube is inserted into the smoke chamber, a limiting sleeve is used to connect the open end of the smoke chamber, so that the end wall of the cigarette rod and the end of the heating film tube are inserted into the limiting groove of the limiting sleeve, thereby making the heating film tube clamped and fixed to the inner wall of the smoke chamber.
[0019] Furthermore, the cigarette cartridge includes an integrally formed cigarette oil storage body and a smoking mouthpiece;
[0020] The smoke oil storage body is inserted into the tube cavity of the heating film tube.
[0021] The oil storage body is inserted into the tube cavity of the heating film tube. When the heating film tube is heated, the oil storage body can undergo a chemical reaction to generate smoke, and the generated smoke is sucked out through the smoking mouthpiece.
[0022] Furthermore, the cigarette holder is configured as a rectangular cigarette holder, and the heating film tube is configured as a rectangular heating film tube. The rectangular heating film tube matches the rectangular cigarette holder, allowing the heating film tube to be better sheathed in the cigarette cavity.
[0023] Furthermore, the cigarette holder is configured as a cylindrical cigarette holder, and the heating film tube is configured as a cylindrical heating film tube. The cylindrical heating film tube matches the cylindrical cigarette holder, enabling the heating film tube to be better sheathed in the cigarette cavity.
[0024] Compared with the prior art, the beneficial effects of the present invention are:
[0025] (1) The utility model relates to a heating film electronic cigarette. Since a heating film tube is provided on the inner wall of the smoke chamber as the heating structure of the electronic cigarette, the heating film tube is directly inserted into the smoke chamber during installation. When the heating film tube needs to be replaced, it can be directly pulled out. It has the advantages of simple structure and easy installation and disassembly. In addition, the cigarette cartridge is inserted into the tube cavity of the heating film tube, so it can prevent the chemical substances generated by the chemical reaction of the cigarette cartridge from being directly deposited on the surrounding wall of the smoke chamber. The generated chemical substances are attached to the tube wall of the heating film tube. When the heating film tube is used for a period of time and the chemical substances attached to the heating film tube are too much and affect the heating and heat transfer of the heating film tube, the heating film tube can be directly pulled out and replaced. Since the production cost of the heating film tube is relatively low, generally 0.5 yuan to 1 yuan per piece, compared with the electronic cigarettes of the prior art that often replace the entire smoke chamber, the present application can avoid replacing the entire smoke chamber, extend the service life of the smoke chamber, and greatly reduce the cost of using the electronic cigarette.
[0026] (2) Compared with the heating structure of the electronic cigarette in the prior art, the heating film electronic cigarette of the present invention adopts a heating film tube that can be installed and removed at any time as the heating structure, which is convenient for replacement and avoids directly replacing the entire cigarette chamber. Therefore, the heating film electronic cigarette has the advantages of simple structure, low production cost and low use cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0038] The terms used in the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. In the present invention, the singular forms "a", "an", "the" and "the" used in the embodiments and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.
[0039] The following describes the details in conjunction with specific embodiments.
[0040] Example 1
[0041] A heating film electronic cigarette in this embodiment, such as Figures 1 to 5 As shown, it includes a cigarette rod 1, a cigarette chamber 2 arranged in the cigarette rod 1, a heating film tube 3 sleeved on the inner wall of the cigarette chamber 2 and made of a heating film, and a cigarette cartridge 5 inserted into the tube cavity 4 of the heating film tube 3.
[0042] The present invention relates to a heating film electronic cigarette. A heating film tube 3 is sheathed on the inner wall of the smoke chamber 2 as the heating structure of the electronic cigarette. The heating film tube 3 is directly inserted into the smoke chamber 2 during installation and can be directly removed when the heating film tube 3 needs to be replaced. This has the advantages of a simple structure and is easy to install and remove. Furthermore, the cigarette cartridge 5 is inserted into the tube cavity 4 of the heating film tube 3. This prevents the chemical substances generated by the chemical reaction of the cigarette cartridge 5 from being directly deposited on the surrounding walls of the smoke chamber 2. The generated chemical substances adhere to the tube wall of the heating film tube 3. After a period of use, if the chemical substances adhere to the heating film tube 3 and affect the heating and heat transfer of the heating film tube 3, the heating film tube 3 can be directly removed and replaced. Since the production cost of the heating film tube 3 is relatively low, generally 0.5 to 1 yuan per piece, compared to the existing electronic cigarettes that require frequent replacement of the entire smoke chamber, the present invention can avoid replacing the entire smoke chamber, extending the service life of the smoke chamber and significantly reducing the cost of using the electronic cigarette.
[0043] In this embodiment, the heating film tube 3 is an integrally formed, rolled and closed heating film tube 3; this structure has the characteristic of simple preparation. In addition, the closed heating film tube 3 can better prevent the chemical substances generated when the cigarette cartridge 5 undergoes a chemical reaction from adhering to the surrounding wall of the smoke chamber 2, which can better extend the service life of the smoke chamber 2 and reduce the use cost of the electronic cigarette.
[0044] In this embodiment, Figure 3 As shown, electrodes 6 are provided at both ends of the heating film tube 3, and the electrodes 6 are connected to wires for electrically connecting to a power source (not shown in the drawings of this application). When the wires connected to the electrodes 6 are connected to a power source, current flows through the wires into the electrodes 6 at both ends of the heating film tube 3, and then flows through the electrodes 6 into the conductive heating layer of the heating film tube 3, causing the heating film tube 3 to heat up due to the inflow of current, thereby heating the cigarette cartridge 5.
[0045] In this embodiment, Figure 4 As shown, a clamping block 7 is provided on the bottom wall of the smoke chamber 2, and a clamping groove 8 for fixing the heating film tube 3 is formed between the clamping block 7 and the side wall of the smoke chamber 2. During the installation process, when the heating film tube 3 is inserted into the smoke chamber 2, it is inserted all the way to the clamping groove 8 formed between the clamping block 7 and the side wall of the smoke chamber 2, so that the clamping block 7 can clamp and fix the heating film tube 3, preventing the heating film tube 3 from loosening and affecting the use of the electronic cigarette.
[0046] In this embodiment, Figure 4 As shown, two clamping blocks 7 are provided on both sides of the bottom wall of the smoke chamber 2; a clamping groove 8 is formed between each clamping block 7 and the side wall of the smoke chamber 2. By providing two clamping blocks 7 on both sides of the bottom wall of the smoke chamber 2, the heating film tube 3 can be better fixed and stabilized.
[0047] In this embodiment, the clamping block 7 is configured as a rectangular parallelepiped clamping block 7. When the heating film tube 3 is in the shape of a rectangular parallelepiped, the clamping block 7 is correspondingly configured as a rectangular parallelepiped, which can better clamp and fix the heating film tube 3.
[0048] In this embodiment, Figure 5 As shown, the cigarette cartridge 5 includes an integrally formed oil storage body 51 and a mouthpiece 52; the oil storage body 51 is inserted into the tube cavity 4 of the heating film tube 3. When the heating film tube 3 is heated, the oil storage body 51 can undergo a chemical reaction to produce smoke, which is then inhaled through the mouthpiece 52.
[0049] In this embodiment, the cigarette rod 1 is a rectangular cigarette rod 1; the heating film tube 3 is a rectangular heating film tube 3. The rectangular heating film tube 3 matches the rectangular cigarette rod 1, so that the heating film tube 3 can be better installed in the cigarette cavity 2.
[0050] Example 2
[0051] A heating film electronic cigarette in this embodiment, such as Figures 6 to 8 As shown, the difference between this embodiment and embodiment 1 is that the bottom wall of the smoke chamber 2 is not provided with a clamping block 7, that is, the heating film electronic cigarette does not fix the heating film tube 3 by the clamping block 7, but fixes the heating film tube 3 by the limiting sleeve 9.
[0052] In this embodiment, the heating film electronic cigarette further includes an annular limiting sleeve 9 for attaching the heating film tube 3 to the inner wall of the smoke chamber 2; a circular limiting groove 91 is formed on one side of the limiting sleeve 9; and the limiting sleeve 9 is sleeved with the open end of the smoke chamber 2. After the heating film tube 3 is inserted into the smoke chamber 2, the limiting sleeve 9 is sleeved with the open end of the smoke chamber 2, so that the ends of the cigarette rod 1 and the heating film tube 3 are both inserted into the limiting groove 91 of the limiting sleeve 9, thereby firmly fixing the heating film tube 3 to the inner wall of the smoke chamber 2.
[0053] The rest of the structure of this embodiment is the same as that of embodiment 1.
[0054] Example 3
[0055] This embodiment is a heating film electronic cigarette. The difference between this embodiment and Example 1 is that the heating film tube 3 is a heating film tube 3 that is not closed after being rolled up. The heating film tube 3 of this structure has the advantages of being simpler to manufacture and having lower manufacturing costs. Even if the heating film tube 3 is not closed, the gap is very small, which can effectively prevent the chemical substances generated by the chemical reaction of the cigarette cartridge 5 from adhering to the surrounding wall of the smoke chamber 2, thereby effectively extending the service life of the smoke chamber 2 and reducing the cost of using the electronic cigarette.
[0056] The rest of the structure of this embodiment is the same as that of embodiment 1.
[0057] Example 4
[0058] This embodiment is a heating film electronic cigarette. The difference between this embodiment and embodiment 1 is that the cigarette rod 1 is set to be a cylindrical cigarette rod 1; the heating film tube 3 is set to be a cylindrical heating film tube 3.
[0059] The rest of the structure of this embodiment is the same as that of embodiment 1.
[0060] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
