Description

Technical Field

[0001] This application relates to the field of electronic cigarette technology, and more specifically to electronic cigarettes. Background Technology

[0002] Current e-cigarettes are generally composed of components such as batteries, circuit boards, atomizing components, oil reservoirs, and mouthpieces. However, when e-cigarettes are not in use, the e-liquid remains in contact with the atomizing components, making it easy for the e-liquid to penetrate the atomizing components and cause long-term immersion and contamination. Summary of the Invention

[0003] In view of this, in order to solve the above-mentioned technical problems, this application provides an electronic cigarette.

[0004] To achieve the above objectives, this application provides an electronic cigarette, which includes a housing, a smoking tube, a push rod, and a piston, wherein...

[0005] The chimney is installed inside the housing and forms an oil storage chamber between it and the housing. The side wall of the chimney is provided with a first through hole.

[0006] One end of the push rod extends into the chimney;

[0007] The piston is located inside the chimney and abuts against the push rod;

[0008] In use, the push rod pushes the piston to move relative to the chimney. The piston moves from the initial position to a preset position relative to the chimney so that the oil storage chamber is connected to the chimney through the first through hole; wherein, when the piston is in the initial position, the first through hole is closed.

[0009] Beneficial effects: Unlike existing technologies, the present application's smoke tube is housed within the casing, forming an oil storage chamber between it and the casing. A first through hole is provided on the side wall of the smoke tube. One end of the push rod extends into the smoke tube. A piston is disposed within the smoke tube and abuts against the push rod. In use, the push rod pushes the piston to move relative to the smoke tube, moving the piston from its initial position to a preset position relative to the smoke tube, allowing the oil storage chamber to communicate with the smoke tube through the first through hole. When the piston is in its initial position, the first through hole is closed. Therefore, when the electronic cigarette is idle, its piston is in its initial position to close the first through hole, thereby reducing the contamination of the atomizing components by e-liquid when the electronic cigarette is idle. When using the electronic cigarette, the push rod can be used to set the piston to the preset position to guide the e-liquid into the smoke tube, achieving e-liquid atomization.

[0038] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the structure of an embodiment of the electronic cigarette of this application; Figure 2 yes Figure 1 A schematic diagram of the structure of a chimney in the image; Figure 3 yes Figure 1 A schematic diagram of the piston structure.

[0040] like Figures 1-3 As shown, the electronic cigarette 10 includes an upper housing 100, a smoke tube 200, a push rod 300, and a piston 400.

[0041] The chimney 200 is disposed inside the upper housing 100 and forms an oil storage chamber 11 between it and the upper housing 100. The side wall of the chimney 200 is provided with a through hole 201, which is referred to as the first through hole 201 below to distinguish it from other through holes. One end of the push rod 300 (hereinafter referred to as the second end) extends into the chimney 200, and the other end of the push rod 300 (hereinafter referred to as the first end) remains outside the housing 100. The piston 400 is disposed inside the chimney 200 and abuts against the second end of the push rod 300.

[0042] Furthermore, when the piston 400 is in the initial position, it closes the first through hole 201. When the piston 400 is in the preset position, it connects the oil storage chamber 11 to the smoke extraction pipe 200 through the first through hole 201.

[0043] The push rod 300 can slide relative to the chimney 200 to set the piston 400 in a preset position. Specifically, the push rod 300 pushes the piston 400 to move relative to the chimney 200, and the piston 400 moves from the initial position to the preset position relative to the chimney 200, so that the oil storage chamber 11 communicates with the chimney 200 through the first through hole 201.

[0044] Beneficial effects: Unlike the prior art, the present application's chimney 200 is disposed inside the upper housing 100, and forms an oil storage chamber 11 between the chimney 200 and the upper housing 100. The side wall of the chimney 200 is provided with a first through hole 201. The first end of the push rod 300 remains outside the upper housing 100, and the second end of the push rod 300 extends into the chimney 200. The piston 400 is disposed inside the chimney 200 and abuts against the second end of the push rod 300. In use, the push rod 300 pushes the piston 400 to move relative to the chimney 200. The piston 400 moves relative to the chimney 200 from the initial position to a preset position, so that the oil storage chamber 11 communicates with the chimney 200 through the first through hole 201. When the piston 400 is in the initial position, the first through hole 201 is closed. Therefore, when the electronic cigarette is idle, the piston 400 is in the initial position to close the first through hole 201, thereby reducing the contamination of the atomizing component by the e-liquid. When the electronic cigarette is in use, the piston 400 can be set to a preset position by the push rod 300 to introduce the e-liquid into the smoking tube 200 to achieve e-liquid atomization.

[0045] In one exemplary embodiment, after the piston 400 is positioned in a preset position using the push rod 300, the push rod 300 is pulled out of the smoke tube 200. This allows the vapor formed by the atomization of e-liquid to be expelled from the electronic cigarette 10 through the smoke tube 200. By using this method, from the time the electronic cigarette 10 leaves the factory until it is used by the user, the piston 400 is kept in its initial position. When the user uses the electronic cigarette 10, the push rod 300 is used to position the piston 400 in the preset position, thus preventing e-liquid from entering the atomization component from the time the electronic cigarette 10 leaves the factory until the user uses it.

[0046] Furthermore, in Figure 1 Based on and refer to, for example Figure 2 and Figure 3 The outer diameter of piston 400 can be equal to the inner diameter of chimney 200. When piston 400 is in the initial position, it closes the first through hole 201.

[0047] The piston 400 may be provided with a second through hole 401 that communicates with the smoke tube 200. When the piston 400 is in a preset position, the second through hole 401 communicates with the first through hole 201 to guide the e-liquid in the oil storage chamber 11 into the smoke tube 200. The second through hole 401 extends toward the side away from the push rod 300.

[0048] like Figure 3 As shown, the piston 400 includes a first ring portion 410 and a second ring portion 420. The second ring portion 420 is sleeved outside the first ring portion 410 and connected to the first ring portion 410 through a bracket 430 to form a second through hole 401 communicating with the smoke pipe 200 between the first ring portion 410 and the second ring portion 420; the push rod 300 abuts against the first ring portion 410.

[0049] When the piston 400 is in the initial position, the second ring 420 closes the first through hole 201. When the piston 400 is in the preset position, the second through hole 401 is connected to the first through hole 201 so as to guide the e-liquid in the oil storage chamber 11 into the smoking pipe 200.

[0050] Optionally, in Figure 3 Based on the above, refer to Figures 4-5 , Figure 4 This is a three-dimensional structural schematic diagram of the piston from a first-view perspective in one embodiment of the electronic cigarette of this application; Figure 5 This is a three-dimensional structural schematic diagram of the piston from a second perspective in one embodiment of the electronic cigarette of this application.

[0051] like Figure 3 , Figure 4 and Figure 5 As shown, in one embodiment, a plurality of supports 430 may be provided between the second ring portion 420 and the first ring portion 410. The supports 430 are respectively connected to the first ring portion 410 and the second ring portion 420, so that when the piston 400 moves within the smoke pipe 200, the first ring portion 410, the second ring portion 420, and the plurality of supports 430 move together. The plurality of supports 430 form a second through hole 401 between each other. The supports 430 include, but are not limited to, spokes (not shown in the figure). The shape of the spokes can be, but is not limited to, a cube, a cuboid, a trapezoid, a prism, a sector, a frustum, or a combination of at least two of them.

[0052] Optionally, in other embodiments (not shown), a connecting ring may be provided between the second ring portion and the first ring portion. The outer end of the connecting ring is connected to the second ring portion, and the inner end of the connecting ring is connected to the first ring portion, so that when the piston moves inside the chimney, the first ring portion moves together with the second ring portion and the connecting ring. A second through hole may be provided in the connecting ring.

[0053] Optionally, in Figure 1 Based on, and in conjunction with reference Figure 3 , Figure 4 and Figure 5 The channel 411 of the first ring portion 410 connects the first end of the smoke extractor 200 and the second end of the smoke extractor 200. In this way, the smoke in the second end of the smoke extractor 200 can be guided to the first end of the smoke extractor 200 through the channel 411 of the first ring portion 410 during the extraction process.

[0054] Optionally, the first ring portion 410 may be provided with a support frame 440 within its channel 411 to divide the channel 411 of the first ring portion 410 into a first air guide segment 402 and a second air guide segment 403. The support frame 440 is provided with an air guide hole 404, which connects the first air guide segment 402 and the second air guide segment 403. The first air guide segment 402 connects to the first end of the smoke pipe 200, and the second air guide segment 403 connects to the second end of the smoke pipe 200.

[0055] Specifically, in Figure 1 Based on, and in conjunction with reference Figure 2 and Figure 3 The channel 210 of the chimney 200 may include a first air guide channel 202 and a first receiving hole 203 that are interconnected. The first air guide channel 202 is connected to a first end of the chimney 200, and the first receiving hole 203 is connected to a second end of the chimney 200. The diameter of the first receiving hole 203 may be larger than the diameter of the first air guide channel 202, so as to form a first stepped surface 220 at the connection between the first air guide channel 202 and the first receiving hole 203. The first through hole 201 may be provided on the side of the first receiving hole 203 away from the first air guide channel 202, and the first ring portion 410 protrudes towards the push rod 300, that is, the first end of the first ring portion 410 can be movably inserted into the first receiving hole 203, such as the first end of the first ring portion 410 can be tightly fitted with the first receiving hole 203. The first stepped surface 220 is used to restrict the piston 400 from moving into the first air guide channel 202.

[0056] In this embodiment, the first end of the first ring portion 410 can slide within the first receiving hole 203, so that the piston 400 is positioned in a preset position by the push rod 300. The sliding of the piston 400 within the first receiving hole 203 is restricted by the first stepped surface 220, so that the piston 400 will not fall out of the chimney 200 from the first air guide channel 202.

[0057] Furthermore, in Figure 1 Based on, and in conjunction with reference Figure 2 and Figure 3 The smoke hood 200 can form a second stepped surface 230 at the end of the first receiving hole 203 facing away from the first air guiding channel 202, and the second ring portion 420 is located on the side of the first receiving hole 203 facing away from the first air guiding channel 202, so that the second stepped surface 230 can be used to restrict the second ring portion 420 from moving into the first receiving hole 203.

[0058] Specifically, the chimney 200 has a second receiving hole 204 formed on the side of the first receiving hole 203 facing away from the first air guide channel 202, which communicates with the first receiving hole 203. The diameter of the second receiving hole 204 is larger than the diameter of the first receiving hole 203, so that a second stepped surface 230 is formed at the connection between the second receiving hole 204 and the first receiving hole 203. The first through hole 201 can be provided in the side wall of the second receiving hole 204. The second ring portion 420 can be movably disposed in the second receiving hole 204.

[0059] In this embodiment, the first ring portion 410 can slide within the first receiving hole 203, while the second ring portion 420 can slide within the second receiving hole 204, so that the piston 400 is positioned in a preset position by the push rod 300. The sliding of the piston 400 within the chimney 200 is restricted by the first stepped surface 220 and the second stepped surface 230, so that the piston 400 will not fall out of the chimney 200 from the first air guide channel 202.

[0060] Alternatively, in other embodiments, a slot (not shown) may be provided on the inner wall of the first ring portion 410 near the push rod 300, and the push rod 300 engages with the slot.

[0061] like Figure 1 , Figure 2 and Figure 3 As shown, a first annular groove 405 may be provided on the outer periphery of the first end of the first ring portion 410, and a first sealing ring (not shown) may be provided in the first annular groove 405 so that when the first end of the first ring portion 410 slides in the first receiving hole 203, the gap between the first ring portion 410 and the periphery of the first receiving hole 203 is sealed.

[0062] A second annular groove 406 may be provided on the outer periphery of the second ring portion 420, and a second sealing ring (not shown) may be provided in the second annular groove 406, so that when the second ring portion 420 slides in the second receiving hole 204, it seals the gap between the second ring portion 420 and the periphery of the second receiving hole 204.

[0063] Further reading Figures 6-9 , Figure 6 This is a schematic diagram of another embodiment of the electronic cigarette of this application; Figure 7 yes Figure 6 A semi-sectional three-dimensional schematic diagram of the assembly structure of the fixed bracket and the oil mesh in the middle; Figure 8 yes Figure 7 Enlarged view of region A in the middle; Figure 9 This is a half-section three-dimensional schematic diagram of the assembly structure of the fixed bracket and the oil mesh in Figure 6.

[0064] like Figures 6-9As shown, another embodiment of the electronic cigarette 10 of this application is obtained by further defining the electronic cigarette 10 of the above embodiment. In this other embodiment, the electronic cigarette 10 further includes an oil cotton 500 and an oil mesh 600.

[0065] The oil cotton 500 is placed inside the smoke tube 200 and located on the side of the piston 400 away from the push rod 300. The oil cotton 500 is used to filter the e-liquid introduced into the smoke tube 200 and then introduce it into the atomizing chamber 800 of the electronic cigarette 10. It also plays a certain buffering role to prevent the e-liquid from soaking the atomizing chamber 800, thereby controlling the consumption rate of the e-liquid.

[0066] The oil filter 600 is positioned between the piston 400 and the oil cotton 500 to filter the e-liquid introduced into the smoke pipe 200 and then introduce it into the oil cotton 500.

[0067] Optionally, the e-liquid filter 600 has multiple mesh openings 611. The size and number of mesh openings 611 can be set according to the desired e-liquid flow rate. Different e-liquid flow rates correspond to different mesh opening sizes and / or numbers. Therefore, the preset size and number of mesh openings 611 are used to define the preset e-liquid flow rate.

[0068] Further, see Figures 6-10 , Figure 10 yes Figure 6 A schematic diagram of the assembly structure of the fixed bracket, oil mesh, oil cotton, atomizing chamber, and sealing base is shown. The electronic cigarette 10 further includes a fixed bracket 700.

[0069] The fixed bracket 700 may include a fixed ring 710 and a fixed cylinder 720 connected to the fixed ring 710. The fixed ring 710 is used to fix the oil mesh 600. The first end of the fixed cylinder 720 extends into the first ring portion 410, and the second end of the fixed cylinder 720 is in communication with the atomizing chamber 800.

[0070] In one exemplary embodiment, the fixing ring 710 may have two oil mesh limiting grooves (not shown) arranged side by side along the axial direction of the fixing cylinder 720 on one side. Each oil mesh limiting groove corresponds to one oil mesh 600. Of course, in other embodiments, there may be one, three, or more oil mesh limiting grooves, and there may also be one, three, or more oil meshes 600. Each oil mesh limiting groove corresponds to one or more oil meshes 600.

[0071] The channel 411 of the first ring 410 connects the first end of the smoke extraction tube 200 to the first end of the fixed tube 720, and the second end of the fixed tube 720 connects to the atomizing chamber 800 to form an air extraction channel.

[0072] In this embodiment, the smoke formed by the atomization of e-liquid in the atomizing chamber 800 is introduced into the fixed tube 720 through the second end of the fixed tube 720, and then exited from the first end of the fixed tube 720. After exiting the fixed tube 720, the smoke is introduced into the first end of the smoking tube 200 through the channel 411 of the first ring 410, so that it flows out from the first end of the smoking tube 200 (in use, the push rod 300 pushes the piston 400 to the preset position and then pulls out the push rod 300).

[0073] Optionally, a spoke (not shown in the figure) may be provided between the fixing ring 710 and the fixing cylinder 720, and the fixing ring 710 is connected to the fixing cylinder 720 through the spoke.

[0074] The first ring portion 410 can slide relative to the fixed cylinder 720 so that the piston 400 is in a preset position.

[0075] Optionally, such as Figures 6-9 A third sealing ring (not shown) may be provided between the outer periphery of the fixed cylinder 720 and the first ring portion 410 to seal the gap between the first ring portion 410 and the outer periphery of the fixed cylinder 720 when the first ring portion 410 slides relative to the fixed cylinder 720. For example, a third annular groove 705 is provided on the outer periphery of the second end of the fixed cylinder 720 extending into the first ring portion 410, and the third sealing ring is disposed in the third annular groove 705.

[0076] Optionally, such as Figures 6-9 The outer periphery of the fixed cylinder 720 is provided with a first limiting groove 703 and a second limiting groove 704, which are spaced apart along the axial direction of the fixed cylinder 720. A buckle protrusion (not shown in the figure) may be provided on the inner wall of the channel 411 of the first ring portion 410. The buckle protrusion can engage with either the first limiting groove 703 or the second limiting groove 704. When the piston 400 is in the initial position, the buckle protrusion engages with the first limiting groove 703; when the piston 400 is in the preset position, the buckle protrusion engages with the second limiting groove 704.

[0077] exist Figure 6 Further reference Figure 10 The channel 721 of the fixed cylinder 720 may include a second air guide channel 701 and a third receiving hole 702 that are interconnected. The second air guide channel 701 is connected to the first end of the fixed cylinder 720, and the third receiving hole 702 is connected to the second end of the fixed cylinder 720. The first end of the atomizing chamber 800 can be inserted into the third receiving hole 702. An oil cotton insertion groove 711 may be provided between the second end of the fixing ring 710 and the second end of the fixed cylinder 720, and oil cotton 500 can be inserted into the oil cotton insertion groove 711.

[0078] Furthermore, the electronic cigarette 10 further includes an oil-sealing base 900, which may be provided with an air inlet 910 communicating with the atomizing chamber 800. The first end of the oil-sealing base 900 is provided with an atomizing chamber insertion slot 920 at intervals around the air inlet 910. The second end of the atomizing chamber 800 can be inserted into the atomizing chamber insertion slot 920, such that the second end of the atomizing chamber 800 can be tightly fitted with the atomizing chamber insertion slot 920.

[0079] In this embodiment, the electronic cigarette 10 further includes an atomizing component, which is disposed inside the smoke tube 200 and located on the side of the piston 400 away from the push rod 300. The atomizing component is used to atomize the e-liquid flowing into the smoke tube 200.

[0080] The atomizing component can be disposed within the atomizing chamber 800. Optionally, the atomizing component may include an inner layer of oil cotton and a heating element. The inner layer of oil cotton may be attached to the inside of the atomizing chamber 800, and the heating element may be disposed within the inner layer of oil cotton. For example, the heating element may be inserted into the inner layer of oil cotton or attached to the inside of the inner layer of oil cotton.

[0081] Please see Figures 11-15 , Figure 11 This is a schematic diagram of another embodiment of the electronic cigarette of this application; Figure 12 yes Figure 11 A schematic diagram of the structure of a chimney in the image; Figure 13 yes Figure 11 A schematic diagram of the piston structure.

[0082] like Figures 11-13 As shown, the electronic cigarette 10a includes an upper housing 100a, a smoking tube 200a, a push rod 300a, and a piston 400a.

[0083] The chimney 200a is disposed inside the upper housing 100a and forms an oil storage chamber 11a between it and the upper housing 100a. The side wall of the chimney 200a is provided with a through hole 201a, which is referred to as the first through hole 201a below to distinguish it from other through holes. The first end of the push rod 300a remains outside the upper housing 100a, and the second end of the push rod 300a extends into the chimney 200a. The piston 400a is disposed inside the chimney 200a and abuts against the second end of the push rod 300a.

[0084] Furthermore, in Figure 11 Based on this, compare and refer to Figure 17 and Figure 18 , Figure 17 This is a schematic diagram of the structure of the electronic cigarette in another embodiment of the present application when the first through hole is in the initial position; Figure 18 This is a schematic diagram of the structure of the electronic cigarette in another embodiment of this application when the first through hole is located in a preset position.

[0085] like Figure 17 As shown, when the piston 400a is in the initial position, it closes the first through hole 201a. At this time, the first through hole 201a is blocked by the second ring portion 420a, so the first through hole 201a... Figure 17 The middle part is invisible. For example... Figure 18 As shown, when the piston 400a is in the preset position, the oil storage chamber 11a is connected to the smoke pipe 200a through the first through hole 201a. At this time, the second ring 420a is offset from the first through hole 201a, so that the second through hole 401a is connected to the first through hole 201a. Therefore, the first through hole 201a is in... Figure 18 The middle is the visible state.

[0086] contrast Figures 17-18 It is known that the push rod 300a can slide relative to the chimney 200a to set the piston 400a in a preset position. Specifically, the push rod 300a pushes the piston 400a to move relative to the chimney 200a, and the piston 400a moves relative to the chimney 200a from the initial position to the preset position, so that the oil storage chamber 11a communicates with the chimney 200a through the first through hole 201a.

[0087] Beneficial effects: Unlike the prior art, the present application has a chimney 200a disposed inside the upper housing 100a, forming an oil storage chamber 11a between the chimney 200a and the upper housing 100a. The side wall of the chimney 200a is provided with a first through hole 201a. The first end of the push rod 300a remains outside the upper housing 100a, and the second end of the push rod 300a extends into the chimney 200a. The piston 400a is disposed inside the chimney 200a and abuts against the second end of the push rod 300a. In use, the push rod 300a pushes the piston 400a to move relative to the chimney 200a. The piston 400a moves relative to the chimney 200a from the initial position to a preset position, so that the oil storage chamber 11a communicates with the chimney 200a through the first through hole 201a. When the piston 400a is in the initial position, the first through hole 201a is closed. Therefore, when the electronic cigarette is idle, the piston 400a is in the initial position to close the first through hole 201a, thereby reducing the contamination of the atomizing component by the e-liquid. When the electronic cigarette 10a is in use, the piston 400a can be set to the preset position by the push rod 300a to introduce the e-liquid into the smoking tube 200a and realize the atomization of the e-liquid.

[0088] In one exemplary embodiment, after the piston 400a is positioned in a preset position using the push rod 300a, the push rod 300a is pulled out of the extraction tube 200a. This allows the vapor formed by the atomization of e-liquid to be expelled from the electronic cigarette 10a through the extraction tube 200a. By using this method, from the time the electronic cigarette 10a leaves the factory until it is used by the user, the piston 400a remains in its initial position. When the user uses the electronic cigarette 10a, the push rod 300a is used to position the piston 400a in the preset position, thus preventing e-liquid from entering the atomization component from the time the electronic cigarette 10a leaves the factory until the user uses it.

[0089] Furthermore, in Figure 11 Based on, and in conjunction with reference Figure 12 and Figure 14 As shown, Figure 14 yes Figure 12 Enlarged schematic diagram of area B. The electronic cigarette 10a includes an oil separator 500a, and an oil filling channel 202a is provided on the side wall of the smoking tube 200a. The oil filling channel 202a connects to the oil storage chamber 11a.

[0090] The oil separator 500a is fixedly installed with the smoke extraction pipe 200a and seals the oil injection channel 202a, and oil is injected into the oil storage chamber 11a through the oil separator 500a.

[0091] In the above manner, when it is necessary to inject oil into the oil storage chamber 11a, oil is injected into the oil storage chamber 11a through the oil separator 500a that seals the oil injection channel 202a, without the need to insert or remove the oil separator 500a. Moreover, the oil separator 500a is integrally set with the smoke extractor 200a. Therefore, the oil separator 500a of this application provides a more durable seal for the oil injection channel 202a.

[0092] In one exemplary embodiment, the oil separator 500a may be provided with an oil injection hole (not shown). The sidewalls of the oil injection hole can be flexibly joined together to close the oil injection hole, thereby restricting the flow of e-liquid stored in the oil storage cavity 11a to the outside through the oil injection hole. At least the portion of the oil separator 500a adjacent to the side edge of the oil injection hole can expand the oil injection hole based on flexible deformation under the pressure of the oil injection member, so as to accommodate the oil injection member to pass through, so that the oil injection member can inject oil into the oil storage cavity 11a.

[0093] In this exemplary embodiment, by means of the above method, when no e-liquid is needed, the sidewalls of the e-liquid injection hole can be flexibly joined together, thereby closing the injection hole and restricting the flow of e-liquid stored in the e-liquid storage chamber 11a to the outside through the injection hole, effectively preventing e-liquid leakage. When e-liquid needs to be injected, the e-liquid injection component is used to squeeze the portion of the oil separator 500a adjacent to the periphery of the injection hole, thereby expanding the injection hole to allow the e-liquid injection component to pass through the oil separator 500a to inject e-liquid into the e-liquid storage chamber 11a. Therefore, in this exemplary embodiment, it is not necessary to set an oil-blocking plug in the e-liquid injection channel 202a, saving the cumbersome operation of inserting and removing the oil-blocking plug during e-liquid replacement.

[0094] The oil injection hole in the oil separator 500a can be set in the oil separator 500a before the product leaves the factory, or it can be set in the oil separator 500a by piercing the oil separator 500a with an oil injection part with a piercing needle after the product leaves the factory.

[0095] Optionally, the grease trap 500a can be integrally formed with the chimney 200a. This provides a strong connection between the grease trap 500a and the chimney 200a, preventing it from easily detaching from the chimney 200a. The grease trap 500a and the chimney 200a are integrally formed using a secondary injection molding process.

[0096] exist Figure 11 Based on, and in conjunction with reference Figure 12 and Figure 14 As shown, the oil separator 500a is located on the side of the chimney 200a away from the oil storage chamber 11a. Thus, when replacing the oil separator 500a, it is not necessary to disassemble the assembly structure of the chimney 200a and the upper housing 100a, facilitating the replacement of the oil separator 500a. Furthermore, when the oil separator 500a is pierced by an oil injection device with a piercing needle, the oil separator 500a will not detach from the chimney 200a and sink into the oil storage chamber 11a due to the force of the needle.

[0097] Furthermore, in Figure 11 Based on, and in conjunction with reference Figure 12 and Figure 14 As shown, a mounting groove 203a can be provided on the side of the smoke extractor 200a away from the oil storage chamber 11a. The oil injection channel 202a penetrates the bottom wall of the mounting groove 203a, and the oil separator 500a is disposed in the mounting groove 203a. In this way, the mounting groove 203a restricts the movement of the oil separator 500a towards the oil storage chamber 11a, preventing the oil separator 500a from falling into the oil storage chamber 11a and causing contamination of the exposed surface of the oil separator 500a and oil leakage.

[0098] Optionally, see Figures 14-16 , Figure 15This is a three-dimensional structural schematic diagram of the oil separator from a first perspective in another embodiment of the electronic cigarette of this application; Figure 16 This is a three-dimensional structural schematic diagram of the oil separator from a second perspective in another embodiment of the electronic cigarette of this application.

[0099] To improve the stability of the assembly structure between the oil separator 500a and the chimney 200a, such as Figure 15-27 As shown, the oil separator 500a can be a ring-shaped component, as shown in the diagram. Figure 14 and Figure 12 As shown, the assembly groove 203a can be an annular groove.

[0100] Furthermore, in Figure 11 Based on, and in conjunction with reference Figure 12 and Figure 14 ,as well as Figure 15 and Figure 16 As shown, the oil separator 500a has an oil injection area 510a, and the thickness of the oil injection area 510a is less than the thickness of other areas 520a of the oil separator.

[0101] In one exemplary embodiment, an oil injection hole can be provided in the oil injection region 510a. Since the thickness of the oil injection region 510a is less than the thickness of other regions 520a of the oil separator 500a, the oil injection hole more easily accommodates the oil injection component passing through. Simultaneously, the greater thickness of the other regions 520a of the oil separator 500a provides higher support strength to the oil injection region 510a, improving the performance of the sidewall of the oil injection hole in the oil injection region 510a in restoring its joined state after flexible deformation expansion. On the other hand, if the thickness of the oil injection region 510a is too small, it is not easy to injection mold; therefore, a certain range needs to be set for the thickness of the oil injection region 510a. Preferably, the thickness of the oil injection region 510a is 0.2-0.4 mm, and more preferably 0.3 mm.

[0102] Optionally, the chimney 200a may be provided with at least one oil filling channel 202a, and correspondingly, the oil separator 500a may be provided with at least one oil filling area 510a. The oil filling areas 510a on the oil separator 500a correspond to the oil filling channels 202a, and each oil filling channel 202a corresponds to at least one oil filling area 510a. Different oil filling areas 510a are separated from each other area 520a of the oil separator 500a. All oil filling areas 510a are provided with at least two oil filling holes.

[0103] For example, in one exemplary embodiment, each oil injection channel 202a corresponds to an oil injection area 510a, and at least two oil injection holes can be provided in the same oil injection area 510a. This allows at least one oil injection hole to be used for oil injection while at least another oil injection hole is used for venting.

[0104] For example, in another exemplary embodiment, the chimney 200a may be provided with at least two oil filling channels 202a, and the oil separator 500a may be provided with at least two oil filling areas 510a. Each oil filling channel 202a is provided with one oil filling area 510a. Each oil filling area 510a is provided with an oil filling hole, so that when the oil filling hole of at least one oil filling area 510a is used for oil filling, the oil filling hole of at least another oil filling area 510a is used for exhaust.

[0105] For example, in another exemplary embodiment (not shown), each oil injection channel is provided with two oil injection areas, which are separated from other areas by an oil separator. Each oil injection area is provided with an oil injection hole, so that when the oil injection hole in one oil injection area is used for oil injection, the oil injection hole in the other oil injection area is used for venting.

[0106] Below, in Figure 11 Based on, and in conjunction with reference Figure 12 and Figure 14 ,as well as Figure 15 and Figure 16 As shown, the oil injection area 510a provided on the oil separator 500a will be used as an example for explanation.

[0107] The grease trap 500a includes two grease filling areas 510a, and the chimney 200a is provided with two grease filling channels 202a. Each grease filling channel 202a corresponds to one grease filling area 510a. Each grease filling area 510a is provided with at least one grease filling hole, so that when the grease filling hole of one grease filling area 510a is used for grease filling, the grease filling hole of the other grease filling area 510a is used for exhaust.

[0108] like Figures 15-16 As shown, a fixing part 530a is provided on the side of the other area 520a of the oil separator 500a near the oil storage chamber 11a, which is used to fix the oil separator 500a to the chimney 200a.

[0109] For example, in one embodiment, the fixing part 530a is a fitting post (not shown in the figure), and the smoke pipe 200a is provided with a fitting groove (not shown in the figure) corresponding to the fitting post. The fixing part 530a of the oil separator 500a is fitted into the side of the smoke pipe 200a away from the oil storage cavity 11a, so as to fix the oil separator 500a and the smoke pipe 200a in a fixed connection.

[0110] For example, in another embodiment, the fixing part 530a is a hook part (not shown in the figure), and the smoke pipe is provided with a hook engaging part (not shown in the figure) corresponding to the hook part. The hook part and the hook engaging part engage to fix the oil separator 500a to the smoke pipe 200a.

[0111] For example, in another embodiment, the fixing part 530a is a threaded connection part (not shown in the figure), and the smoke hood 200a is provided with a threaded mating part corresponding to the threaded connection part. The end of the threaded connection part near the oil storage cavity 11a extends into the threaded mating part and is threadedly connected to the threaded mating part. The end of the threaded connection part away from the oil storage cavity 11a passes through the other area 520a of the oil separator 500a on the side away from the oil storage cavity 11a and presses against the oil separator 500a to fix the oil separator 500a to the smoke hood 200a.

[0112] Of course, in other embodiments, the oil separator 500a and the chimney 200a can also be connected by adhesive bonding or other methods, which are not limited here.

[0113] This application further proposes an oil storage device for an electronic cigarette, the oil storage device comprising: a housing 100a; a smoke tube 200a disposed within the housing 100a and forming an oil storage cavity 11a between the smoke tube 200a and the housing 100a, the smoke tube 200a having an oil injection channel 202a; and an oil separator 500a fixedly disposed with the smoke tube 200a and sealing the oil injection channel 202a, and injecting oil into the oil storage cavity 11a through the oil separator 500a; wherein the oil separator 500a is integrally disposed with the smoke tube 200a.

[0114] The electronic cigarette 10a consists of a shell 100a, a smoke tube 200a, and an oil separator 500a, which together form its oil storage device. For a detailed description of the oil storage device, please refer to the above-mentioned embodiment of the electronic cigarette, which will not be repeated here.

[0115] Furthermore, in Figure 11 Based on and refer to, for example Figure 12 and Figure 13 The outer diameter of piston 400a can be equal to the inner diameter of the chimney. When piston 400a is in the initial position, it closes the first through hole 201a.

[0116] The piston 400a may be provided with a second through hole 401a that communicates with the smoke chamber 200a. When the piston 400a is in a preset position, the second through hole 401a communicates with the first through hole 201a to guide the e-liquid in the oil storage chamber 11a into the smoke chamber 200a.

[0117] like Figure 13 As shown, the piston 400a includes a first ring portion 410a and a second ring portion 420a. The second ring portion 420a is sleeved outside the first ring portion 410a and connected to the first ring portion 410a through a bracket 430a, so as to form a second through hole 401a communicating with the smoke pipe 200a between the first ring portion 410a and the second ring portion 420a; the push rod 300a abuts against the first ring portion 410a.

[0118] Comparative Reference Figure 17 and Figure 18 ,like Figure 17 As shown, when the piston 400a is in the initial position, the second ring 420a closes the first through hole 201a. At this time, the first through hole 201a is blocked by the second ring 420a, so the first through hole 201a... Figure 17 The middle part is invisible. For example... Figure 18 As shown, when the piston 400a is in the preset position, the second through hole 401a is connected to the first through hole 201a to guide the e-liquid in the oil storage chamber 11a into the smoke tube 200a. At this time, the second ring portion 420a is offset from the first through hole 201a so that the second through hole 401a is connected to the first through hole 201a. Therefore, the first through hole 201a is in... Figure 18 The middle is the visible state.

[0119] Optionally, in Figure 13 Based on the above, refer to Figures 19-20 , Figure 19 This is a three-dimensional structural schematic diagram of the piston from a first-view perspective in another embodiment of the electronic cigarette of this application; Figure 20 This is a three-dimensional structural schematic diagram of the piston from a second perspective in another embodiment of the electronic cigarette of this application.

[0120] like Figure 13 , Figure 19 and Figure 20 As shown, in one embodiment, a plurality of supports 430a may be provided between the second ring portion 420a and the first ring portion 410a. The supports 430a are respectively connected to the first ring portion 410a and the second ring portion 420a, so that when the piston 400a moves within the smoke chamber 200a, the first ring portion 410a, together with the second ring portion 420a and the plurality of supports 430a, moves together. The plurality of supports 430a form a second through hole 401a between each other. The supports 430a include, but are not limited to, spokes (not shown in the figure). The shape of the spokes can be, but is not limited to, a cube, a cuboid, a trapezoid, a prism, a sector, a frustum, or a combination of at least two of them.

[0121] Optionally, in other embodiments (not shown), a connecting ring may be provided between the second ring portion and the first ring portion. The outer end of the connecting ring is connected to the second ring portion, and the inner end of the connecting ring is connected to the first ring portion, so that when the piston moves inside the chimney, the first ring portion moves together with the second ring portion and the connecting ring. A second through hole may be provided in the connecting ring.

[0122] Optionally, in Figure 11 Based on, and in conjunction with reference Figure 13 , Figure 19 and Figure 20The channel 411a of the first ring portion 410a connects the first end of the smoke extractor 200a and the second end of the smoke extractor 200a. Thus, through the channel 411a of the first ring portion 410a, the smoke in the second end of the smoke extractor 200a can be guided to the first end of the smoke extractor 200a during suction.

[0123] exist Figure 11 Based on this, refer to Figure 13 , Figure 19 and Yu Figure 20 The first ring portion 410a protrudes along the axial direction of the smoke extractor 200a toward the push rod 300a. In this way, the size of the push rod 300a can be made smaller.

[0124] The piston 400a has a second boss 440a on the inner wall near the push rod 300a. The second boss 440a is flush with the end face of the piston 400a near the push rod 300a, and the push rod 300a abuts against the second boss 440a.

[0125] In one exemplary embodiment, the second boss 440a may be an arc-shaped segment extending circumferentially along the inner wall of the piston 400a, thereby making the airflow formed in the channel 411a of the first ring portion 410a more stable during suction.

[0126] Specifically, in Figure 11 Based on, and in conjunction with reference Figure 12 , Figure 13 and Figure 14 The first ring portion 410a protrudes along the axial direction of the smoke tube 200a toward the push rod 300a, and the push rod 300a abuts against the first ring portion 410a; the smoke tube 200a includes a first cylindrical portion 210a and a second cylindrical portion 220a along the axial direction of the smoke tube 200a, the inner diameter of the first cylindrical portion 210a is smaller than the inner diameter of the second cylindrical portion 220a, so as to form a first boss 230a in the smoke tube 200a; the first ring portion 410a is disposed in the first cylindrical portion 210a, and when the piston 400a is in a preset position, the second ring portion 420a abuts against the first boss 230a.

[0127] In this embodiment, the first end of the first ring portion 410a can slide within the first cylindrical portion 210a, so that the piston 400a is set in a preset position by the push rod 300a. The first boss 230a restricts the sliding of the second ring portion 420a into the first cylindrical portion 210a, so that the piston 400a will not fall out of the smoke pipe 200a from the first cylindrical portion 210a.

[0128] Among them, Figure 11 Based on, and in conjunction with reference Figure 12 and Figure 13 ,as well as Figure 19 and Figure 20In one embodiment, the radius of the second end of the push rod 300a may be smaller than the inner diameter of the piston 400a near the end of the push rod 300a.

[0129] For example, the inner wall of the first ring portion 410a near the push rod 300a is provided with a second boss 440a, and the push rod 300a abuts against the second boss 440a.

[0130] The second boss 440a extends to the end face of the first ring portion 410a near the end of the push rod 300a, and the first ring portion 410a abuts against the push rod 300a through the second boss 440a. In this way, the radius of the second end of the push rod 300a can be smaller than the inner diameter of the first ring portion 410a.

[0131] The smoke extraction pipe 200a includes a channel 204a for the first cylinder 210a and a channel 206a for the second cylinder 220a. The channel 411a of the first ring 410a connects the first cylinder 210a and the second cylinder 220a. Thus, during extraction, the smoke inside the second cylinder 220a can be guided to the first cylinder 210a through the channel 411a of the first ring 410a.

[0132] Alternatively, in other embodiments (not shown), a groove or block may be provided at one end of the push rod that abuts against the first ring. This groove or block engages with the hook at the free end of the second boss.

[0133] like Figure 11 , Figure 12 and Figure 13 As shown, a first annular groove 402a may be provided on the outer periphery of the first end of the first ring portion 410a, and a first sealing ring (not shown) may be provided in the first annular groove 402a, so that when the first end of the first ring portion 410a slides in the first cylindrical portion 210a, the gap between the first ring portion 410a and the first cylindrical portion 210a is sealed.

[0134] The outer periphery of the second ring portion 420a may be provided with a second annular groove 403a and a third annular groove 404a arranged axially at intervals along the second ring portion 420a. The second annular groove 403a and the third annular groove 404a may be respectively provided with a second sealing ring (not shown) and a third sealing ring, so as to seal the gap between the second ring portion 420a and the second cylinder portion 220a when the second ring portion 420a slides within the second cylinder portion 220a. The second annular groove 403a and the third annular groove 404a may be arranged axially along the smoke extraction pipe 200a.

[0135] exist Figure 11 Based on this, refer to Figure 12As shown, the electronic cigarette 10a further includes a liquid-absorbing component 600a, which is sleeved on the outside of the push rod 300a and fixedly installed with the smoke tube 200a. It is used to absorb the condensate formed in the smoke tube 200a. At the same time, the liquid-absorbing component 600a can also fix the push rod 300a and improve the stability of the push rod 300a.

[0136] Smoke easily condenses inside the smoke tube 200a, forming condensate. If this condensate is inhaled, it will spoil the user's smoking experience. To address this, a condensate-absorbing component 600a is installed outside the push rod 300a. This component absorbs the condensate inside the smoke tube 200a, minimizing or preventing condensate from flowing out of the smoke tube 200a and thus improving the user's smoking experience.

[0137] Further reading Figures 21-23 , Figure 21 This is a structural schematic diagram of yet another embodiment of the electronic cigarette of this application; Figure 22 yes Figure 21 A half-section three-dimensional schematic diagram of the assembly structure of the piston, fixed bracket and buffer component; Figure 23 yes Figure 22 An exploded view of the fixed support in the diagram.

[0138] like Figures 21-23 As shown, another embodiment of the electronic cigarette 10a of this application is obtained by further defining the electronic cigarette 10a of the other embodiment described above. In this other embodiment, the electronic cigarette 10a further includes a cushioning member 700a and an oil cotton 800a.

[0139] The oil cotton 800a is installed inside the smoke tube 200a and is located on the side of the piston 400a away from the push rod 300a. The oil cotton 800a is used to filter the e-liquid introduced into the smoke tube 200a and then introduce it into the atomizing chamber 1100a of the electronic cigarette.

[0140] The buffer 700a is positioned between the piston 400a and the oil filter 800a, and is used to filter the e-liquid introduced into the smoke tube 200a before introducing it into the oil filter 800a. The buffer 700a can be, but is not limited to, an oil filter.

[0141] Optionally, the buffer 700a is provided with multiple mesh openings (not shown). The size and number of mesh openings can be set according to the required e-liquid flow rate. Different e-liquid flow rates correspond to different mesh opening sizes and / or numbers. Therefore, the preset size and number of mesh openings are used to define the preset e-liquid flow rate.

[0142] Further, see Figures 21-24 , Figure 24 yes Figure 21A schematic diagram of the assembly structure of the fixed bracket, buffer, oil cotton, atomizing component, and sealing base is shown. The electronic cigarette 10a further includes a fixed bracket 900a. The fixed bracket 900a includes a fixing ring 910a and a fixing cylinder 920a.

[0143] The fixing ring 910a is fixedly connected to the smoke tube 200a, and the buffer 700a is disposed on the fixing ring 910a; the first end of the fixing cylinder 920a extends into the first ring portion 410a, and the second end of the fixing cylinder 920a is fixed to the fixing ring 910a, so that the piston 400a can move from the initial position to the preset position along the fixing cylinder 920a relative to the smoke tube 200a.

[0144] like Figures 21-24 As shown, the channel 411a of the first ring 410a connects the smoking tube 200a and the channel 921a of the fixed tube 920a, and the channel 921a of the fixed tube 920a connects to the atomizing chamber. That is, the smoking tube 200a, the channel 411a of the first ring 410a, the channel 921a of the fixed tube 920a and the atomizing chamber of the electronic cigarette form an air intake channel (in use, the push rod 300a pushes the piston 400a to the preset position, and then the push rod 300a is pulled out).

[0145] In this embodiment, the smoke formed by the atomization of e-liquid in the atomization chamber is introduced into the fixed tube 920a through the second end of the fixed tube 920a, and then exited from the first end of the fixed tube 920a. After exiting the fixed tube 920a, the smoke is introduced into the first end of the smoking pipe 200a through the channel 411a of the first ring portion 410a, so as to flow out from the smoking pipe 200a.

[0146] like Figures 22-23 As shown, the first ring portion 410a can slide along the fixed cylinder 920a so that the piston 400a is in a preset position.

[0147] like Figures 22-23 As shown, the outer surface of the fixed cylinder 920a is provided with a first limiting part 922a. When the piston 400a is in the preset position, the end face of the first ring part 410a away from the push rod 300a abuts against the first limiting part 922a. The first ring part 410a extends along its axial direction toward the end away from the push rod 300a with a second limiting part 450a. When the piston 400a is in the initial position, the second limiting part 450a abuts against the first limiting part 922a.

[0148] The second limiting part 450a and the first limiting part 922a can cooperate with each other to provide damping when the piston 400a slides back and forth relative to the smoke pipe 200a.

[0149] Optionally, the first limiting part 922a may protrude from the outer surface of the fixed cylinder 920a, and the second limiting part 450a may include a hook rod (not shown) and a hook block (not shown). One end of the hook rod is connected to the first ring part 410a, and the hook block is disposed at the other end of the hook rod 451a and protrudes towards the fixed cylinder 920a. The hook block can engage with the first limiting part 922a to provide damping when the piston 400a slides back and forth relative to the smoke pipe 200a.

[0150] Specifically, when the piston 400a is in the initial position, the hook block is located on the side of the first limiting part 922a adjacent to the first cylinder 210a, and the first limiting part 922a is used to restrict the movement of the hook block to the side of the first limiting part 922a away from the first cylinder 210a; when the piston 400a is in the preset position, the hook block is located on the side of the first limiting part 922a away from the first cylinder 210a, and the first limiting part 922a is used to restrict the movement of the hook block to the side of the first limiting part 922a adjacent to the first cylinder 210a.

[0151] Thus, by engaging the latching block with the first limiting part 922a, damping is provided when the piston 400a slides back and forth relative to the smoke pipe 200a. This prevents the piston 400a from switching between the initial position and the preset position under the action of a small external force, thereby avoiding or reducing the accidental switching of the piston 400a.

[0152] Optionally, the second end of the fixing cylinder 920a can abut against the fixing ring 910a, such as... Figures 22-23 As shown, the fixing ring 910a may include an inner ring portion 911a, an outer ring portion 912a, and a connecting frame 913a.

A buffer 700a is disposed in the first storage space 914a. An oil-soaked cotton 800a may be disposed on the side of the connecting frame 913a opposite to the first storage space 914a. The 800a oil-soaked cotton and the 700a cushioning material can extend towards each other to be joined together.

[0153] In one exemplary embodiment, the retaining ring 910a can be pressed against the second end of the retaining cylinder 920a. For example, the second end of the retaining cylinder 920a extends into the inner ring portion 911a, and the inner ring portion 911a can be pressed against the second end of the retaining cylinder 920a. This makes the connection between the retaining ring 910a and the retaining cylinder 920a more stable and less prone to loosening. Furthermore, the retaining ring 910a and the retaining cylinder 920a can be pre-formed during manufacturing, and then the inner ring portion 911a is pressed against the second end of the retaining cylinder 920a, facilitating the manufacturing of the retaining bracket 900a.

[0154] Optionally, such as Figures 22-23 A fourth sealing ring (not shown in the figure) may be provided between the outer periphery of the fixed cylinder 920a and the first ring portion 410a to seal the gap between the first ring portion 410a and the outer periphery of the fixed cylinder 920a when the first ring portion 410a slides along the fixed cylinder 920a. For example, a fourth annular groove 923a is provided on the outer periphery of the second end of the fixed cylinder 920a extending into the first ring portion 410a, and the fourth sealing ring is disposed in the fourth annular groove 923a.

[0158] Optionally, the sealing base 1000a has a first wiring hole 1003a and a second wiring hole 1004a between the atomizing chamber insertion slot 1002a and the air guide hole 1001a. Both the first wiring hole 1003a and the second wiring hole 1004a penetrate the sealing base 1000a on both the side adjacent to the atomizing chamber 1101a and the side away from the atomizing chamber 1101a. In this way, the positive and negative terminals of the circuit components on the side of the sealing base 1000a adjacent to the atomizing chamber 1100a and the side of the sealing base 1000a away from the atomizing chamber 1100a can be separated through the first wiring hole 1003a and the second wiring hole 1004a, thereby reducing the probability of short circuits.
