Description

Technical Field

[0001] This invention relates to the field of electronic cigarette technology, and in particular to an electronic cigarette. Background Technology

[0002] Currently, e-cigarettes heat the cigarette, allowing it to produce smoke for customers to inhale without burning, while also reducing the tar content in the smoke; thus, e-cigarettes can serve as a substitute for regular cigarettes.

[0003] In related technologies, electronic cigarettes mostly include a housing assembly and a heating assembly. The heating assembly is located inside the housing assembly and has a heating chamber for heating the cigarette. The housing assembly has an air inlet and an air outlet. One end of the heating chamber is connected to the air inlet, and the other end is connected to the air outlet. During operation, the heating assembly heats the cigarette placed inside the heating chamber, causing the cigarette to produce smoke. The airflow enters the heating chamber through the air inlet and mixes with the smoke. The airflow mixed with smoke then flows out of the air outlet and is inhaled by the user.

[0004] However, when the heating element is fitted onto the cigarette, the heat from the outer wall of the heating element will be conducted to the outside through the e-cigarette's casing, resulting in heat loss from the heating element and reducing the utilization rate of the heat inside the heating element. Summary of the Invention

[0005] The present invention aims to provide an electronic cigarette to solve the technical problem of heat loss in the heating component in the prior art.

[0006] The present invention addresses its technical problems by adopting the following technical solutions:

[0007] An electronic cigarette is provided, comprising:

[0008] A housing assembly having a receiving cavity, an air inlet, and an air outlet, wherein the air inlet and the air outlet are located on the same side of the housing assembly;

[0009] A heating assembly is provided, which is placed within the accommodating cavity and connected to the housing assembly. A communicating cavity is formed between the end of the heating assembly away from the air inlet and the bottom wall of the accommodating cavity. A cigarette heating chamber is provided within the heating assembly, and an air intake channel is formed between the outer wall of the heating assembly and the inner wall of the accommodating cavity. One end of the air intake channel is connected to the air inlet, and the other end is connected to the cigarette heating chamber via the communicating cavity. The cigarette heating chamber is connected to the air outlet. A guide groove is provided on the housing assembly, positioned between the air inlet and the air intake channel, which is connected to the air inlet via the guide groove. The guide groove includes a vertical groove and an inclined groove that communicate with each other. The central axis of the vertical groove is parallel to the central axis of the accommodating cavity, and the central axis of the inclined groove is inclined relative to the central axis of the accommodating cavity. The inclined groove extends downward from the lower part of the vertical groove and surrounds the outer side of the heating assembly.

[0010] In some embodiments, the housing assembly includes a main body, a fixed bracket, and a cigarette holder. The main body has the receiving cavity. The fixed bracket is placed in the receiving cavity and connected to the main body. The cigarette holder is detachably connected to the main body. The fixed bracket and the cigarette holder together form the air inlet. The cigarette holder and the fixed bracket are both sleeved on the heating component. The cigarette holder and the fixed bracket together clamp one end of the heating component. The guide groove is formed on the fixed bracket, and the air outlet is formed on the cigarette holder.

[0011] In some embodiments, the heating assembly is in the shape of a straight tube, and the end of the heating assembly near the air inlet is provided with a flared portion. The flared portion includes an annular inclined section and an annular straight section. In the direction from the cigarette heating chamber to the air outlet, the annular inclined section and the annular straight section are arranged sequentially and connected to each other. The fixed bracket has a first clamping groove, and the cigarette holder has a second clamping groove. The annular inclined section is placed in the first clamping groove, and the outer wall of the annular inclined section abuts against the groove wall of the first clamping groove. The annular straight section is partially placed in the second clamping groove, and the groove wall of the second clamping groove abuts against the end of the annular straight section near the air inlet, so that the cigarette holder and the fixed bracket jointly clamp the flared portion.

[0012] In some embodiments, the housing assembly further includes a flexible rubber ring, which is sleeved on the outer side wall of the annular straight section. The cigarette holder and the fixed bracket clamp the flexible rubber ring. The portion of the annular straight section away from the air inlet relative to the flexible rubber ring is placed in the first clamping groove, and the portion of the annular straight section closer to the air inlet relative to the flexible rubber ring is placed in the second clamping groove.

[0013] In some embodiments, the electronic cigarette further includes a power supply assembly installed within the main body. A first electrical connection groove and a second electrical connection groove are formed on the groove wall of the first clamping groove. The housing assembly further includes a first conductive component and a second conductive component. One end of the first conductive component is connected to one electrode of the power supply assembly, and the other end passes through the groove wall of the first electrical connection groove and extends into the first electrical connection groove. One end of the second conductive component is connected to another electrode of the power supply assembly, and the other end passes through the groove wall of the second electrical connection groove and extends into the second electrical connection groove. The heating assembly further includes a first electrode connection portion and a second electrode connection portion. Both the first electrode connection portion and the second electrode connection portion are connected to the outer wall of the annular straight section. The portion of the first conductive component extending into the first electrical connection groove abuts against the first electrode connection portion, and the portion of the second conductive component extending into the second electrical connection groove abuts against the second electrode connection portion.

[0014] In some embodiments, both the first electrical connection groove and the second electrical connection groove are annular and surround the annular straight section along the outer wall of the annular straight section; the first conductive component includes a first elastic connection portion, which is placed in the first electrical connection groove and undergoes elastic deformation, and under the action of elastic force, the first elastic connection portion abuts against the first electrode connection portion; the second conductive component includes a second elastic connection portion, which is placed in the second electrical connection groove and undergoes elastic deformation, and under the action of elastic force, the second elastic connection portion abuts against the second electrode connection portion.

[0015] In some embodiments, the housing assembly further includes a top cover component connected to the main body. The top cover component has a connecting cavity communicating with the air inlet. Multiple limiting portions are provided on the inner wall of the connecting cavity, all of which surround the central axis of the receiving cavity, and a clearance groove is provided between adjacent limiting portions. The cigarette holder includes a holder body and multiple abutment portions connected to the outer wall of the holder body. The cigarette holder is rotatable relative to the main body, such that the abutment portion aligns with the corresponding clearance groove; or the abutment portion abuts against the corresponding limiting portion, and the limiting portion clamps the cigarette holder with the flexible rubber ring, making the cigarette holder detachably connected to the main body. The clearance groove allows the corresponding abutment portion to pass through, enabling the cigarette holder to extend out of the receiving cavity.

[0016] In some embodiments, the cigarette holder further includes a holder body and a plurality of cigarette holders, the cigarette holders being connected to the holder body and placed inside the air outlet, all of the cigarette holders surrounding the central axis of the air inlet, and there being a gap between adjacent cigarette holders.

[0017] In some embodiments, the electronic cigarette further includes a cigarette holder support connected to the housing assembly, the cigarette holder support extending into the cigarette heating chamber and having a gap between it and the chamber wall of the cigarette heating chamber, and the portion of the cigarette holder support extending into the cigarette heating chamber having a cigarette receiving groove.

[0018] In some implementations, the electronic cigarette also includes an ejector component and a resilient ejector component. The housing assembly further includes a switch component, and the cigarette holder support is connected to the ejector component. The housing assembly has a mounting cavity, in which the ejector component is placed. The switch component can engage with the ejector component, allowing the ejector component to be positioned within the mounting cavity. The resilient ejector component is located between the ejector component and the cavity wall of the mounting cavity, and provides elasticity to the ejector component in the direction extending out of the mounting cavity.

[0019] Compared to existing technologies, the heating element maintains a high temperature on both its inner and outer walls when heating the cigarette. As outside air flows through the air intake channel, it makes full contact with the outer wall of the heating element, carrying away heat from the outer wall before contacting the cigarette. This reduces the likelihood of heat loss from the heating element and improves its heat utilization efficiency. Furthermore, the higher temperature of the gas flowing into the cigarette heating chamber reduces the temperature difference between the air and the smoke, thus decreasing the likelihood of the air absorbing heat from the smoke and causing condensation during mixing. Simultaneously, the airflow direction within the air intake channel is opposite to that within the cigarette heating chamber. This change in airflow direction as the air passes through the connecting cavity, where the cavity wall acts as a buffer, allowing for more thorough mixing of the air and smoke upon entering the heating chamber.

[0020] Furthermore, the central axis of the inclined groove is inclined in the direction from the air inlet to the air intake channel, so that the guide groove can guide the gas. When the air flows into the air intake channel, the air flows along the central axis of the guide groove. The air intake channel as a whole has a columnar structure with an annular cross-section. The outer wall of the heating component and the inner wall of the accommodating cavity can guide the air flowing in the air intake channel, so that the air can flow in a spiral in the air intake channel. This allows the air to come into more full contact with the outer wall of the heating component during the flow in the air intake channel, and to carry the heat of the outer wall of the heating component to the cigarette heating chamber, further improving the utilization rate of the heat in the heating component in this embodiment.

They are used only for the convenience of describing the present invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention.

[0041] The following detailed description of an electronic cigarette 100 provided in this application, with reference to all the accompanying drawings, and through specific embodiments, will be provided in detail.

[0042] Please refer to Figures 1 to 5One embodiment of the present invention discloses an electronic cigarette 100, including a housing assembly 10 and a heating assembly 20. The housing assembly 10 has a receiving cavity 102, an air inlet 104, and an air outlet 106, with the air inlet 104 and the air outlet 106 located on the same side of the housing assembly 10. The heating assembly 20 is placed inside the receiving cavity 102 and connected to the housing assembly 10. The end of the heating assembly 20 away from the air inlet 104 forms a communicating cavity 1022 with the bottom wall of the receiving cavity 102. A cigarette heating cavity 202 is formed inside the heating assembly 20. An air intake channel 1020 is formed between the outer side wall of the heating assembly 20 and the inner side wall of the receiving cavity 102. One end of the air intake channel 1020 is connected to the air inlet 104. 4. The other end is connected to the cigarette heating chamber 202 via the connecting cavity 1022, and the cigarette heating chamber 202 is connected to the air outlet 106; a guide groove 108 is provided on the housing assembly 10, and the guide groove 108 is placed between the air inlet 104 and the air inlet channel 1020, and the air inlet channel 1020 and the air inlet 104 are connected via the guide groove 108; the guide groove 108 includes a vertical groove 1086 and an inclined groove 1088 that are connected to each other, the central axis of the vertical groove 1086 is parallel to the central axis of the receiving cavity 102, and the central axis of the inclined groove 1088 is inclined relative to the central axis of the receiving cavity 102. The inclined groove 1088 extends downward from the lower part of the vertical groove 1086 and surrounds the outside of the heating assembly 20.

[0043] With the above structure, during the process of the customer inhaling the electronic cigarette 100, the heating component 20 heats the cigarette placed in the cigarette heating chamber 202, so that the cigarette can produce smoke; outside air enters into the air inlet 104, and then flows into the cigarette heating chamber 202 after passing through the air inlet channel 1020 and the connecting chamber 1022 in sequence, and mixes with the smoke. Finally, the mixture of air and smoke flows out of the receiving chamber 102 along the air outlet 106 and is provided to the user for inhalation.

[0044] During the above process, the heating component 20 heats the cigarette at high temperatures on both its inner and outer walls. As outside air flows through the air inlet channel 1020, it fully contacts and absorbs heat from the outer wall of the heating component 20. This heat is then carried into the cigarette heating chamber 202 as the air flows in, reducing the likelihood of heat loss from the heating component 20 and improving its heat utilization rate. Furthermore, the higher temperature of the air flowing into the cigarette heating chamber 202 reduces the temperature difference between the air and the smoke, thus decreasing the likelihood of the air absorbing heat from the smoke and causing condensation during mixing. Simultaneously, the airflow direction within the air inlet channel 1020 is opposite to that within the cigarette heating chamber 202. Consequently, the airflow direction is changed when passing through the connecting cavity 1022, and the cavity wall of the connecting cavity 1022 acts as a buffer, allowing for more thorough mixing of the air with the smoke when it reaches the cigarette heating chamber 202.

[0045] Furthermore, in the direction from the air inlet 104 to the air intake channel 1020, the central axis of the inclined groove 1088 is inclined, so that the guide groove 108 can guide the gas. When air flows into the air intake channel 1020, the air flows along the central axis of the guide groove 108. The air intake channel 1020 is a columnar structure with an annular cross-section. The outer wall of the heating component 20 and the inner wall of the accommodating cavity 102 can guide the air flowing in the air intake channel 1020, so that the air can flow in a spiral line in the air intake channel 1020. This allows the air to come into more full contact with the outer wall of the heating component 20 during the flow in the air intake channel 1020, and to carry the heat of the outer wall of the heating component 20 to the cigarette heating chamber 202, further improving the utilization rate of the heat in the heating component 20 in this embodiment.

[0046] Specifically, the electronic cigarette 100 also includes a power supply component 30 (see reference). Figure 8 The power supply component 30 is housed within the housing component 10 and is used to supply power to the heating component 20. In this embodiment, the accommodating cavity 102 is generally cylindrical, the heating component 20 is generally tubular, and the air intake channel 1020 is generally cylindrical with an annular cross-section, and the cigarette heating cavity 202 is generally cylindrical. In other embodiments, the accommodating cavity 102 may also be of other shapes, such as a cuboid; the heating component 20 may also be of other shapes, such as a hollow frustum; correspondingly, the air intake channel 1020 and the cigarette heating cavity 202 may also have other structures.

[0047] In this embodiment, the electronic cigarette 100 includes a pop-out component 50, and the housing assembly 10 also has a mounting cavity 107. The mounting cavity 107 communicates with the receiving cavity 102. The receiving cavity 102 penetrates one end face of the housing assembly 10, and the mounting cavity 107 penetrates the other opposite end face of the housing assembly 10. The pop-out component 50 is placed inside the mounting cavity 107 and is detachably connected to the cavity wall of the mounting cavity 107 by a plug-in connection. The end of the pop-out component 50 facing the air inlet 104 is the bottom wall of the receiving cavity 102, and the end of the heating assembly 20 facing away from the air inlet 104 forms a communicating cavity 1022 with the pop-out component 50. Therefore, when tar or tobacco residue adheres to the surface of the pop-out component 50, the pop-out component 50 can be disassembled relative to the cavity wall of the mounting cavity 107 and the pop-out component 50 can be cleaned, thereby reducing the possibility of blockage in the communicating cavity 1022. In other embodiments, the housing assembly 10 can also be integrally formed.

[0048] The guide channel 108 includes an air inlet end 1082 and an air outlet end 1084, with the air inlet end 1082 being closer to the air inlet 104 than the air outlet end 1084. From a viewing angle from the air inlet 104 to the air inlet channel 1020, the guide channel 108 overlaps with the air inlet channel 1020. In this embodiment, there are three guide channels 108, and these three guide channels 108 are arranged around the outer wall of the heating assembly 20 along its central axis, with equal spacing between adjacent guide channels 108. The guide channel 108 includes a vertical channel 1086 and an inclined channel 1088 that are interconnected. The central axis of the vertical channel 1086 is parallel to the central axis of the accommodating cavity 102, and the central axis of the inclined channel 1088 is inclined relative to the central axis of the accommodating cavity 102. The end of the vertical channel 1086 away from the inclined channel 1088 is the air inlet end 1082, and the air inlet 104 is connected to the vertical channel 1086 through the air inlet end 1082. The end of the inclined channel 1088 away from the vertical channel 1086 is the air outlet end 1084, and the inclined channel 1088 is connected to the air intake channel 1020 through the air outlet end 1084. When air flows through the guide channel 108, the vertical channel 1086 plays a role in concentrating and guiding the flowing air, allowing the air to flow into the inclined channel 1088 along the direction from the air inlet 104 to the air intake channel 1020. The inclined channel 1088 can better change the flow direction of the concentrated airflow.

[0049] In other embodiments, the number of guide channels 108 may be other, such as two or four; the guide channels 108 may also have other structures, such as the guide channels 108 only including inclined channels 1088.

[0050] In some embodiments, the housing assembly 10 includes a main body 11, a fixed bracket 12, and a cigarette holder 13. The main body 11 has a receiving cavity 102. The fixed bracket 12 is placed in the receiving cavity 102 and connected to the main body 11. The cigarette holder 13 is detachably connected to the main body 11. The fixed bracket 12 and the cigarette holder 13 together form an air inlet 104. The cigarette holder 13 and the fixed bracket 12 are both sleeved on the heating component 20. The cigarette holder 13 and the fixed bracket 12 together hold one end of the heating component 20. A guide groove 108 is formed in the fixed bracket 12, and an air outlet 106 is formed in the cigarette holder 13.

[0051] With the above structure, when the cigarette holder 13 is connected to the main body 11, the cigarette holder 13 and the fixed bracket 12 together clamp the end of the heating component 20 near the air inlet 104, so that the heating component 20 is fixed relative to the main body 11; when the cigarette holder 13 is disassembled from the main body 11, the heating component 20 is released from the main body 11; so that the heating component 20 is detachable from the main body 11, and when the surface of the heating component 20 is covered with tar, tobacco residue and other debris, the debris may be placed in the cigarette heating chamber 202 or the air inlet channel 1020 and cause blockage; when the heating component 20 is disassembled from the main body 11, the heating component 20 is taken out from the receiving cavity 102 and cleaned, which can reduce the possibility of blockage of the cigarette heating chamber 202 or the air inlet channel 1020.

[0052] In addition, the fixed bracket 12 and the cigarette holder 13 together form an air inlet 104, and the guide groove 108 is placed between the air inlet 104 and the air inlet channel 1020. When the cigarette holder 13 is disassembled relative to the main body 11 and placed outside the receiving cavity 102, the customer can use tools such as a brush to reach into the guide groove 108 and clean the guide groove 108.

[0053] Specifically, in this embodiment, the fixing bracket 12 has a cylindrical structure. A connector 122 protrudes from the outer wall of the fixing bracket 12 for connection with the main body 11. The connector 122 has a threaded hole, and the corresponding main body 11 also has a threaded hole. The fixing bracket 12 and the main body 11 are fixedly connected by screws. In other embodiments, the fixing bracket 12 can also be other structures, such as a hollow cuboid; the fixing bracket 12 can also be fixedly connected to the main body 11 by other means, such as welding or adhesive.

[0054] In other embodiments, the heating component 20 may also be detachably connected to the housing component 10 in other ways, such as the outer wall of the heating component 20 being connected to the side wall of the accommodating cavity 102 via a connecting rod; or the end of the heating component 20 being connected to the bottom wall of the accommodating cavity 102.

[0055] Please refer to Figure 6 and Figure 7In some embodiments, the heating component 20 is in the shape of a straight tube. The heating component 20 has a flared portion 22 at one end near the air inlet 104. The flared portion 22 includes an annular inclined section 224 and an annular straight section 222. In the direction from the cigarette heating chamber 202 to the air outlet 106, the annular inclined section 224 and the annular straight section 222 are arranged in sequence and connected to each other. The fixed bracket 12 has a first clamping groove 1202, and the cigarette holder 13 has a second clamping groove 1302. The annular inclined section 224 is placed in the first clamping groove 1202, and the outer wall of the annular inclined section 224 abuts against the groove wall of the first clamping groove 1202. The annular straight section 222 is partially placed in the second clamping groove 1302, and the groove wall of the second clamping groove 1302 abuts against the end of the annular straight section 222 near the air inlet 104, so that the cigarette holder 13 and the fixed bracket 12 jointly clamp the flared portion 22.

[0056] With the above structure, during the assembly of the electronic cigarette 100, the fixing bracket 12 is connected to the main body 11, and then the heating component 20 is placed in the receiving cavity 102, so that the outer wall of the annular inclined section 224 abuts against the groove wall of the first clamping groove 1202, thereby the fixing bracket 12 can support the heating component 20. Then, the cigarette holder 13 is connected to the main body 11, and the groove wall of the second clamping groove 1302 abuts against one end of the annular straight section 222 near the air inlet 104. The cigarette holder 13 and the fixing bracket 12 can clamp the flared part 22, and the heating component 20 can be fixed relative to the housing component 10. With this setting, the installation of the electronic cigarette 100 is more convenient.

[0057] Specifically, the heating component 20 is a cylindrical structure with a flared end 22, which is closer to the air inlet 104 than other parts of the heating component 20. The fixed bracket 12 has an inwardly inclined wall at the end away from the air outlet 106, forming a frustum-shaped space 12022 adapted to the annular inclined section 224. The first clamping groove 1202 includes the frustum-shaped space 12022, and the annular inclined section 224 is placed in the frustum-shaped space 12022, with the outer wall of the annular inclined section 224 abutting against the inclined wall, and thus the outer wall of the annular inclined section 224 abutting against the groove wall of the first clamping groove 1202. The second clamping groove 1302 is opened on the inner side wall of the air outlet 106, and the second clamping groove 1302 penetrates the end face of the cigarette holder 13 facing the heating component 20, so that the groove wall of the second clamping groove 1302 abuts against the end of the annular straight section 222 near the air inlet 104. In the direction from the air inlet 104 to the air intake channel 1020, the sum of the depth of the first clamping groove 1202 and the depth of the second clamping groove 1302 is adapted to the height of the flared portion 22, so that the groove wall of the first clamping groove 1202 and the groove wall of the second clamping groove 1302 can jointly clamp the flared portion 22, thereby the cigarette holder 13 and the fixed bracket 12 jointly clamp the end of the heating component 20 near the air inlet 104.

[0058] In some embodiments, the housing assembly 10 further includes a flexible rubber ring 14, which is sleeved on the outer side wall of the annular straight section 222. The cigarette holder 13 and the fixed bracket 12 clamp the flexible rubber ring 14. The portion of the annular straight section 222 away from the air inlet 104 relative to the flexible rubber ring 14 is placed in the first clamping groove 1202, and the portion of the annular straight section 222 near the air inlet 104 relative to the flexible rubber ring 14 is placed in the second clamping groove 1302.

[0059] With the above structure, the flexible rubber ring 14 is clamped by the cigarette holder 13 and the fixed bracket 12, thereby sealing the gap between the cigarette holder 13 and the fixed bracket 12, improving the sealing performance of the air inlet 104, and allowing the gas in the air inlet 104 to flow into the air intake channel 1020 through the guide groove 108. In addition, the flexible rubber ring 14 is sleeved on the outer wall of the annular straight section 222, and the flexible rubber ring 14 and the outer wall of the flared part 22 together seal the first clamping groove 1202.

[0060] Specifically, the flexible rubber ring 14 is annular. In this embodiment, the flexible rubber ring 14 is made of silicone material. Under the clamping action of the cigarette holder 13 and the fixed bracket 12, the flexible rubber ring 14 undergoes elastic deformation, creating pressure between the flexible rubber ring 14 and the cigarette holder 13, which in turn creates pressure between the cigarette holder 13 and the main body 11. Simultaneously, there is also pressure between the cigarette holder 13 and the heating component 20, i.e., pressure exists between the groove wall of the second clamping groove 1302 and the end of the flared portion 22 near the air inlet 104. The heating component 20 is under balanced force, suggesting that there is also pressure between the outer wall of the annular inclined section 224 and the groove wall of the first clamping groove 1202, making the heating component 20 more firmly fixed and further improving the sealing effect within the second clamping groove 1302. In other embodiments, the flexible rubber ring 14 can also be in other shapes, such as rectangular or elliptical; the flexible rubber ring 14 can also be made of other materials, such as fiberglass or rubber.

[0061] Please refer to Figure 8 , Figure 9 and Figure 10 In some embodiments, the electronic cigarette 100 further includes a power supply assembly 30, which is installed within the main body 11. A first electrical connection groove 1204 and a second electrical connection groove 1206 are formed on the groove wall of the first clamping groove 1202. The housing assembly 10 further includes a first conductive component 15 and a second conductive component 16. One end of the first conductive component 15 is connected to an electrode of the power supply assembly 30, and the other end passes through the groove wall of the first electrical connection groove 1204 and extends into the first electrical connection groove 1204. One end of the second conductive component 16 is connected to the power supply assembly 30. The other end of the other electrode of component 30 passes through the wall of the second electrical connection groove 1206 and extends into the second electrical connection groove 1206; the heating assembly 20 also includes a first electrode connection portion 24 and a second electrode connection portion 26, both of which are connected to the outer wall of the annular straight section 222. The portion of the first conductive component 15 extending into the first electrical connection groove 1204 abuts against the first electrode connection portion 24, and the portion of the second conductive component 16 extending into the second electrical connection groove 1206 abuts against the second electrode connection portion 26.

[0062] With the above structure, the first electrode connection part 24 is electrically connected to one electrode of the power supply assembly 30 via the first conductive component 15, and the second electrode connection part 26 is electrically connected to the other electrode of the power supply assembly 30 via the second conductive component 16. Thus, only the flared part 22 needs to be placed in the first clamping groove 1202 to enable the heating component 20 to be electrically connected to the power supply assembly 30. No additional connection method is required between the heating component 20 and the power supply assembly 30, which further simplifies the assembly process of the electronic cigarette 100 and reduces production costs.

[0063] Specifically, in this embodiment, both the first electrical connection groove 1204 and the second electrical connection groove 1206 are formed on the groove wall of the first clamping groove 1202 away from the outer wall of the flared portion 22; both the first electrical connection groove 1204 and the second electrical connection groove 1206 are annular, and the central axis of the first electrical connection groove 1204 and the central axis of the second clamping groove 1302 are collinear with the central axis of the heating assembly 20. The first conductive component 15 is an annular sheet of metal, which surrounds the outer wall of the annular straight section 222 and is coaxially arranged with the annular straight section 222; the second conductive component 16 has the same structure as the first conductive component 15.

[0064] In other embodiments, the first electrical connection groove 1204 may also be in other shapes, such as rectangular; the first conductive component 15 may also be in other structures, such as rectangular or circular sheet metal; the second conductive component 16 may also be different from the first conductive component 15.

[0065] In some embodiments, both the first electrical connection groove 1204 and the second electrical connection groove 1206 are annular and surround the annular straight section 222 along its outer sidewall; the first conductive component 15 includes a first elastic connection portion 152, which is placed in the first electrical connection groove 1204 and undergoes elastic deformation, and under the action of elastic force, the first elastic connection portion 152 abuts against the first electrode connection portion 24; the second conductive component 16 includes a second elastic connection portion, which is placed in the second electrical connection groove 1206 and undergoes elastic deformation, and under the action of elastic force, the second elastic connection portion abuts against the second electrode connection portion 26.

[0066] With the above structure, the first elastic connection portion 152 abuts against the first electrode connection portion 24, thereby enabling the first elastic connection portion 152 to contact the first electrode connection portion 24 more stably, so that the first conductive component 15 and the first electrode connection portion 24 have a more stable electrical connection relationship; similarly, the second conductive component 16 and the second electrode connection portion 26 have a more stable electrical connection relationship.

[0067] Specifically, in this embodiment, the first conductive component 15 further includes an annular connecting segment 154. The annular connecting segment 154 has a sheet-like structure and is connected to the groove wall of the first electrical connection groove 1204 away from the flared portion 22. There is a gap between the annular connecting segment 154 and the first electrode connecting portion 24. There are four first elastic connecting portions 152, and all the first elastic connecting portions 152 surround the central axis of the annular connecting segment 154. The first elastic connecting portion 152 has an arc-shaped sheet-like structure and is made by folding the annular connecting segment 154. The first elastic connecting portion 152 protrudes inward relative to the annular connecting segment 154. One side of the first elastic connecting portion 152 is connected to the annular connecting segment 154, and one arc-shaped surface of the first elastic connecting portion 152 abuts against the first electrode connecting portion 24. The structure of the second conductive component 16 is the same as that of the first conductive component 15.

[0068] In other embodiments, the first elastic connection portion 152 may also have other shapes, for example, the first electrode connection portion 24 may be annular in shape, and the first elastic connection portion 152 may include only one; the structure of the second conductive component 16 may also be different from the structure of the first conductive component 15.

[0069] Please refer to Figure 11 , Figure 12 and Figure 13 In some embodiments, the housing assembly 10 further includes a top cover component 17, which is connected to the main body 11. The top cover component 17 has a connecting cavity 1702, which communicates with the air inlet 104. Multiple limiting portions 172 are provided on the inner wall of the connecting cavity 1702, all of which surround the central axis of the receiving cavity 102. A clearance groove 109 is provided between adjacent limiting portions 172. The cigarette holder 13 includes a holder body 132 and multiple abutment portions 134. The abutment portion 134 is connected to the outer side wall of the bracket body 132; the cigarette holder 13 can rotate relative to the main body 11, so that the abutment portion 134 is aligned with the corresponding relief groove 109; or the abutment portion 134 abuts against the corresponding limiting portion 172, and the limiting portion 172 and the flexible rubber ring 14 clamp the cigarette holder 13, so that the cigarette holder 13 is detachably connected to the main body 11; the relief groove 109 is used for the corresponding abutment portion 134 to pass through, so that the cigarette holder 13 can extend out of the receiving cavity 102.

[0070] With the above structure, during the installation of the cigarette holder 13 onto the main body 11, it is only necessary to align the abutment portion 134 with the clearance groove 109, then place the cigarette holder 13 into the receiving cavity 102 and abut against the flexible rubber ring 14, causing the flexible rubber ring 14 to undergo elastic deformation; then rotate the cigarette holder 13 so that the abutment portion 134 aligns with the limiting portion 172. Under the elastic force of the flexible rubber ring 14, the limiting portion 172 can be pressed tightly against the abutment portion 134, and the cigarette holder 13 is fixed relative to the main body 11. During the disassembly of the cigarette holder 13 from the main body 11, it is only necessary to rotate the cigarette holder 13 until the abutment portion 134 aligns with the clearance groove 109, and then remove the cigarette holder 13 along the receiving cavity 102. Therefore, the cigarette holder 13 in this embodiment is easier to assemble and disassemble relative to the main body 11.

[0071] Specifically, in this embodiment, there are three limiting parts 172 and three accommodating grooves 109. The limiting part 172 has an arc-shaped block structure. The arc length of the limiting part 172 is greater than the arc length of the accommodating groove 109. When the user inhales the electronic cigarette 100, the external gas can enter the air inlet 104 through the accommodating groove 109. The end of the cigarette holder 13 away from the heating component 20 is also provided with a flared opening, and there are three abutment parts 134. The abutment parts 134 are generally rectangular in shape, and the length of the abutment parts 134 is adapted to the arc length of the relief groove 109. One side of the abutment part 134 is connected to the outer wall corresponding to the flared opening of the cigarette holder 13. The abutment part 134 is provided on the end face of the abutment part 134 facing away from the heating component 20. When the cigarette holder 13 is connected to the main body 11, the abutment part 134 abuts against the limiting part 172. When the cigarette holder 13 rotates relative to the main body 11 until the abutment part 134 is placed in the relief groove 109, under the elastic force of the flexible rubber ring 14, the cigarette holder 13 can move a certain distance away from the heating component 20, so that the user can know that the abutment part 134 is about to be aligned with the relief groove 109. Therefore, the disassembly process of the cigarette holder 13 is easier to operate.

[0072] In other embodiments, the limiting portion 172 may include other quantities, such as four or five; the arc length of the limiting portion 172 may also be less than or equal to the arc length of the relief groove 109; the limiting portion 172 may also be other structures, such as a cylinder.

[0073] In some embodiments, the cigarette holder 13 further includes a holder body 132 and a plurality of cigarette holders 136. The cigarette holders 136 are connected to the holder body 132 and placed inside the air outlet 106. All the cigarette holders 136 surround the central axis of the air inlet 104, and there is a gap between two adjacent cigarette holders 136.

[0074] With the above structure, when the cigarette is placed in the cigarette heating chamber 202, the cigarette holder 136 can contact the side wall of the cigarette and fix it in place, reducing the possibility of the cigarette directly contacting the chamber wall of the cigarette heating chamber 202, thereby reducing the possibility of the cigarette surface being scorched by heat. In addition, by applying force to the cigarette holder 136, it is easier to make the cigarette holder 13 rotate relative to the main body 11, thereby making it easier to assemble and disassemble the cigarette holder 13 relative to the main body 11.

[0075] Specifically, in this embodiment, the cigarette holder 136 has a trapezoidal sheet structure; in other embodiments, the cigarette holder 136 may also have other shapes, such as a hemispherical or rectangular sheet structure.

[0076] Please refer to the following: Figure 2 In some embodiments, the electronic cigarette 100 further includes a cigarette support member 40, which is connected to the housing assembly 10. The cigarette support member 40 extends into the cigarette heating chamber 202 and has a gap with the chamber wall of the cigarette heating chamber 202. The portion of the cigarette support member 40 extending into the cigarette heating chamber 202 is provided with a cigarette receiving groove 402.

[0077] With the above structure, when the cigarette is placed in the cigarette receiving groove 402, the cigarette receiving groove 402 can clamp one end of the cigarette. Combined with the cigarette clamping member 136 fixing the cigarette, the cigarette can be placed more stably in the cigarette heating chamber 202 without contacting the chamber wall of the cigarette heating chamber 202. The cigarette support member 40 extends into the cigarette heating chamber 202, so that the end of the cigarette can also be heated, thereby making the cigarette more evenly heated.

[0078] Specifically, the cigarette support 40 is connected to the ejector component 50. The cigarette support 40 has a rod-shaped structure, and the cigarette receiving groove 402 is cylindrical. The cigarette receiving groove 402 is located at the end of the cigarette support 40 away from the ejector component 50. Furthermore, the cigarette support 40 is also detachable from the main body 11, and the cigarette support 40 is easy to clean or replace.

[0079] Please refer to Figure 14 and Figure 15 In some embodiments, the electronic cigarette 100 further includes a pop-out component 50 and an elastic ejection component 70. The housing assembly 10 also includes a switch component 60. The cigarette holder support 40 is connected to the pop-out component 50. The housing assembly 10 has an installation cavity 107. The pop-out component 50 is placed in the installation cavity 107. The switch component 60 can engage with the pop-out component 50 so that the pop-out component 50 is placed in the installation cavity 107. The elastic ejection component 70 is disposed between the pop-out component 50 and the cavity wall of the installation cavity 107 and provides elastic force to the pop-out component 50 in the direction extending out of the installation cavity 107.

[0080] With the above structure, when the pop-out component 50 in this embodiment needs to be cleaned, the switch component 62 is moved so that the switch component 62 exits the limiting groove, and the switch component 60 loses its abutment with the inner wall of the limiting groove 502; then, because the elastic ejection component 70 is continuously subjected to the pressure of the guide inclined wall 1073 toward the outside of the mounting cavity 107, the elastic ejection component 70 drives the pop-out component 50 to move in the direction of extending out of the mounting cavity 107, making the pop-out component 50 easier to disassemble relative to the housing assembly 10, and the pop-out component 50 easier to clean.

[0081] Specifically, the mounting cavity 107 is formed in the main body 11, and a sliding groove 1072 is formed on the cavity wall of the mounting cavity 107. The switch component 60 is placed in the sliding groove 1072. The switch component 60 includes a switch element 62 and an elastic reset element 64. The elastic reset element 64 is placed between the switch element 62 and the inner wall of the sliding groove 1072. Along the direction of extending out of the sliding groove 1072, the elastic reset element 64 provides elastic force to the switch element 62, so that the switch component 60 can extend into or out of the sliding groove 1072.

[0082] The pop-out component 50 includes a first cylindrical segment 52, a second cylindrical segment 54, and a first abutting surface 56. The first abutting surface 56 is shaped like a frustum, and both the first abutting surface 56 and the second abutting surface are cylindrical. The first abutting surface 56 is positioned between the first cylindrical segment 52 and the second cylindrical segment 54. A limiting groove 502 for the switch component 62 to be inserted is provided on the first abutting surface 56. The limiting groove 502 is annular and surrounds the first abutting surface 56.

[0083] The housing assembly 10 also includes an elastic ejector component 70. The ejector component 50 has an ejector mounting hole 504, which is cylindrical and has two ends that pass through the second cylindrical section 54. The elastic ejector component 70 is placed inside the ejector mounting hole 504. The cavity wall of the mounting cavity 107 includes a guide inclined wall 1073, which forms a frustum-shaped space. The elastic ejector component 70 includes an elastic element 72 and two ejector components 74. One end of the elastic element 72 is connected to one ejector component 74, and the other end is connected to the other ejector component 74. The elastic element 72 can provide elastic force to the ejector component 74 in the direction of extending out of the ejector mounting hole 504. Under the elastic force of the elastic element 72, the ejector component 74 extends out of the ejector mounting hole 504 and abuts against the guide inclined wall 1073. As a result, there is pressure between the guide inclined wall 1073 and the elastic element 72. The resultant force of the pressure on the two elastic elements 72 is directed outward from the mounting cavity 107.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; under the concept of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of the present invention as described above, which are not provided in detail for the sake of brevity; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
