Description

Technical Field

[0001] This application belongs to the field of atomizing device technology, and particularly relates to a leak-proof structure, an atomizer, and an atomizing device. Background Technology

[0002] An atomizing device is a device used to heat an aerosol matrix to atomize it into an aerosol. An atomizing device includes an atomizer, which stores the aerosol matrix. The aerosol matrix can permeate into the atomizing core assembly of the atomizer, which heats the aerosol matrix. During actual transportation, the aerosol matrix may enter the atomizing core assembly, potentially leading to aerosol matrix leakage. Utility Model Content

[0003] The purpose of this application is to provide a leak-proof structure, atomizer, and atomizing device to solve the technical problem in the prior art where the aerosol matrix in the atomizing device may enter the atomizing core assembly during actual transportation, leading to aerosol matrix leakage.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] The first aspect of this application provides a leakage-proof structure, comprising:

[0006] A support base is used to support the atomizer coil assembly within the atomizer's reservoir.

[0007] A protective sleeve is fixedly connected to one end of the support base and is used to cover the atomizing core assembly;

[0008] The connecting rod is connected to the end of the protective sleeve away from the support base, and the connection strength between the connecting rod and the protective sleeve is greater than the connection strength between the support base and the protective sleeve.

[0009] In some implementations, the protective sleeve includes a first sleeve body, a second sleeve body, and a connecting sleeve. The first sleeve body is fitted onto the support base, and the connecting sleeve is located between the first sleeve body and the second sleeve body. The connecting sleeve connects the first sleeve body and the second sleeve body, and the connecting sleeve has a thin-walled structure to form a breakable part.

[0010] In some implementations, the first body includes an end face and a circumferential portion. The end face is located at one end of the support base near the second body and is connected to the connecting sleeve. The circumferential portion is located on the circumferential outer side of the support base and is connected to the end face. The circumferential outer side of the circumferential portion forms a first annular protrusion for sealing with the liquid storage tank.

[0011] In some implementations, the second sleeve includes an upper sleeve and a lower sleeve. One end of the upper sleeve is connected to the lower sleeve, and the lower sleeve is connected to the connecting sleeve. The outer diameter of the lower sleeve is larger than that of the upper sleeve. A second annular protrusion is provided on the inner side of the lower sleeve for sealing with the atomizing core assembly, and a third annular protrusion is provided on the outer side of the upper sleeve for sealing with the liquid storage tank.

[0012] In some implementations, the protective sleeve has an easily cuttable portion that is connected to the outer circumferential side of the connecting rod. The thickness of the connecting rod connected to the easily cuttable portion along the axial direction of the connecting rod is less than a set thickness value.

[0013] In some implementations, one end of the connecting rod is inserted into the protective sleeve, and the end of the connecting rod inside the protective sleeve forms a first region and a second region. The first region and the second region are arranged sequentially along the direction in which the connecting rod extends into the protective sleeve. The first region is connected to the inner surface of the protective sleeve, and there is a gap between the second region and the inner surface of the protective sleeve. The part of the protective sleeve that is connected to the first region forms an easily cuttable part.

[0014] In some implementations, the support base and the protective sleeve are integrally formed; and / or, the protective sleeve and the connecting rod are integrally formed.

[0015] In some implementations, the support includes a first base part, a second base part, and a base connecting plate. The first base part and the second base part are arranged at intervals along the distribution direction of the support and the protective sleeve. There is one or more base connecting plates and the base connecting plates connect the first base part and the second base part. The first base part is provided with a base air inlet.

[0016] In some implementations, a liquid injection hole is provided on the support base, which is connected to the end opening on the protective sleeve, and a plug is provided inside the liquid injection hole.

[0017] In some implementations, the protective sleeve and connecting rod are made of silicone; and / or, the support base is made of plastic.

[0018] The second aspect of this application provides an atomizer, including a liquid reservoir, an atomizing core assembly, and a leak-proof structure as provided in any of the above technical solutions. The atomizing core assembly is supported in the liquid reservoir by a support base of the leak-proof structure. A protective sleeve of the leak-proof structure covers the outside of the atomizing core assembly. The end of the protective sleeve away from the support base is sealed to the liquid reservoir. A connecting rod of the leak-proof structure extends out through a mouthpiece on the liquid reservoir. When a force is applied to the connecting rod in a direction away from the support base, the support base and the protective sleeve can be broken off, and the protective sleeve can be moved to a target position.

[0019] In some implementations, a cutting section is formed on the inner side of the liquid storage tank. When the protective sleeve is in the target position and force is applied to the connecting rod in a direction away from the support, the connection between the protective sleeve and the connecting rod can be severed through the cutting section.

[0020] In some implementations, the cutting section includes a first cutting surface and a second cutting surface, which are connected to form a cutting end. The first cutting surface is closer to the connecting rod than the second cutting surface, and the second cutting surface is inclined away from the connecting rod in the direction from the direction of proximity to the cutting end to the direction of distance from the cutting end.

[0021] In some implementations, the liquid storage tank includes a liquid storage tank body and a suction nozzle. One end of the suction nozzle extends into and connects the liquid storage tank body. The end of the suction nozzle located outside the liquid storage tank body forms a suction opening. The end of the protective sleeve away from the support base extends into the suction nozzle and seals with the inner side of the suction nozzle. A cutting portion is formed on the inner side of the suction nozzle.

[0022] A third aspect of this application provides an atomizing device, including a power supply unit and an atomizer as described in any of the above technical solutions, one end of the atomizer being connected to the power supply unit.

[0023] The beneficial effects of this application are as follows: The leak-proof structure provided in this application embodiment can isolate the aerosol matrix inside the atomizer from the atomizer core assembly because the atomizer core assembly can be fitted inside the protective sleeve and the protective sleeve is fixedly connected to the support base. This prevents the aerosol matrix from entering the atomizer core assembly when the atomizer is not in use (such as during transportation or sales). In this application embodiment, the protective sleeve has a breakable part, and because the connection strength of the breakable part is less than the connection strength between the connecting rod and the protective sleeve, when force is applied to the connecting rod in a direction away from the support base, the leak-proof structure can break at the breakable part, and the broken protective sleeve can move to the target position. At this time, the aerosol matrix inside the atomizer can seep into the atomizer core assembly. Attached Figure Description

[0063] Please see Figures 1-5 , Figure 1 This is a schematic diagram of the structure of the atomizer 100 provided in the embodiments of this application. Figure 2 This is an exploded view of the atomizer 100 provided in the embodiments of this application. Figure 3 Cross-sectional view of the atomizer 100 provided in the embodiments of this application. Figure 1 , Figure 4Cross-sectional view of the atomizer 100 provided in the embodiments of this application. Figure 2 , Figure 5 Cross-sectional view of the atomizer 100 provided in the embodiments of this application. Figure 3 .

[0064] The atomizer 100 provided in this embodiment includes a liquid storage tank 20, an atomizing core assembly 30, and a leak-proof structure 10. Please refer to... Figure 1 The diagram illustrates the liquid storage tank 20, with a suction nozzle 221 formed at one end; please refer to... Figure 2 The diagram illustrates the liquid storage chamber 20, the atomizing core assembly 30, and the leak-proof structure 10.

[0065] Please see Figure 3 The liquid storage chamber 20 is hollow inside and the atomizing core assembly 30 is disposed inside the liquid storage chamber 20. When the atomizing core assembly 30 is in working condition, the atomizing core assembly 30 can heat the aerosol matrix that has penetrated into the atomizing core assembly 30 to make it evaporate. When the user inhales through the mouthpiece 221 of the liquid storage chamber 20, when there is airflow inside the atomizing core assembly 30, the evaporated aerosol matrix forms mist under the condensation effect of the airflow, and the mist flows with the airflow to the mouthpiece 221.

[0066] Please see Figure 2 In this embodiment of the application, the leak-proof structure 10 includes a support base 11, a protective sleeve 12 and a connecting rod 13. The protective sleeve 12 is fixedly connected to the support base 11, and the connecting rod 13 is connected to the end of the protective sleeve 12 away from the support base 11.

[0067] Please see Figure 3 The support base 11 is inserted into the liquid storage tank 20, and the support base 11 and the liquid storage tank 20 are sealed together. The atomizing core assembly 30 is inserted into the support base 11, and the atomizing core assembly 30 is supported in the liquid storage tank 20 by the support base 11. Please refer to [link / reference]. Figure 3 The protective sleeve 12 of the leak-proof structure 10 covers the outer periphery of the atomizing core assembly 30. The protective sleeve 12 is fixedly connected to the support base 11 in the circumferential direction. The end of the protective sleeve 12 away from the support base 11 is sealed to the liquid storage tank 20. The connecting rod 13 of the leak-proof structure 10 extends out through the nozzle 221 on the liquid storage tank 20.

[0068] In one example, see Figure 2 The atomizing core assembly 30 includes an atomizing core 31 and an atomizing base 32. The atomizing core 31 is disposed at one end of the atomizing base 32, and the atomizing base 32 is inserted into the support seat 11, with the atomizing base 32 and the support seat 11 in a sealed fit. Please refer to [link / reference]. Figure 3 This illustrates that a sealing ring 40 is fitted on the atomizing base 32, and the sealing ring 40 is used to achieve a sealed fit between the atomizing base 32 and the support base 11.

[0069] It is worth noting that, Figure 3 The illustrated cross-sectional view of the atomizer 100 shows the atomizer 100 in an unused state, i.e., its state after leaving the factory. In this state, the protective sleeve 12 is fixedly connected to the support base 11 circumferentially. Furthermore, due to the sealing fit between the end of the protective sleeve 12 away from the support base 11 and the liquid reservoir 20, as well as the sealing fit between the support base 11 and the liquid reservoir 20, please refer to [reference needed]. Figure 3 This creates a placement cavity 60 for the aerosol matrix between the protective sleeve 12 and the liquid storage chamber 20. Since the atomizing core assembly 30 is fitted inside the protective sleeve 12 and the protective sleeve 12 is fixedly connected to the support base 11 in the circumferential direction, the protective sleeve 12 isolates the aerosol matrix in the placement cavity 60 from the atomizing core assembly 30. The aerosol matrix in the placement cavity 60 cannot flow into the atomizing core assembly 30, thereby preventing the aerosol matrix in the placement cavity 60 from entering the atomizing core assembly 30 when the atomizer 100 is in an unused state (such as during transportation or sales).

[0070] In this embodiment, the protective sleeve 12 has a breakable portion, and the connection strength of the breakable portion is less than the connection strength between the connecting rod 13 and the protective sleeve 12. When a force is applied to the connecting rod 13 in a direction away from the support base 11, the leak-proof structure 10 can break at the breakable portion.

[0071] Specifically, when the atomizer 100 provided in this application embodiment needs to be used, force needs to be applied to the connecting rod 13 in a direction away from the support base 11, so that the leak-proof structure 10 breaks at the breakable part and the broken protective sleeve 12 is moved to the target position. Please refer to Figure 4 The diagram illustrates the broken protective sleeve 124 and its location at the target position. At this time, the broken protective sleeve 124 is sealed to the atomizing core assembly 30 and the liquid storage chamber 20. The broken protective sleeve 124, the atomizing core assembly 30, the support base 11 and the liquid storage chamber 20 still form a placement cavity 60 for placing the aerosol matrix. The aerosol matrix in the placement cavity 60 is in contact with the atomizing core assembly 30, and the aerosol matrix can penetrate into the atomizing core assembly 30.

[0072] Please see Figure 4 After the protective sleeve 124 breaks, one end is still connected to a connecting rod 13. When the protective sleeve 124 is in the target position, the connecting rod 13 needs to be separated from the protective sleeve 124. Please refer to [link to relevant documentation]. Figure 5 , Figure 5 The connecting rod 13 is not shown in the diagram, meaning that the atomizer 100 can be used normally after the connecting rod 13 is separated from the broken protective sleeve 124.

[0073] In this embodiment, since the atomizing core assembly 30 can be fitted inside the protective sleeve 12 and the protective sleeve 12 is fixedly connected to the support base 11, the protective sleeve 12 isolates the aerosol matrix inside the atomizer 100 from the atomizing core assembly 30. This prevents the aerosol matrix from entering the atomizing core assembly 30 when the atomizer 100 is not in use (e.g., during transportation or sales). It also prevents the aerosol matrix from being immersed in the atomizing core assembly 30 for a long time when the atomizer 100 is not in use, thus affecting the taste of the aerosol produced when the atomizer 100 is in use. In this embodiment, the protective sleeve 12 has a breakable part, and since the connection strength of the breakable part is less than the connection strength between the connecting rod 13 and the protective sleeve 12, when force is applied to the connecting rod 13 in a direction away from the support base 11, the leak-proof structure 10 can break at the breakable part, and the broken protective sleeve 12 can be moved to the target position. At this time, the aerosol matrix can penetrate into the atomizing core assembly 30.

[0074] In one embodiment, please refer to Figure 3 The protective sleeve 12 includes a first sleeve body 121, a second sleeve body 122, and a connecting sleeve 123. The first sleeve body 121 is fitted onto the support base 11. The connecting sleeve 123 is located between the first sleeve body 121 and the second sleeve body 122. The connecting sleeve 123 connects the first sleeve body 121 and the second sleeve body 122. The connecting sleeve 123 has a thin-walled structure to form a breakable part on the protective sleeve 12.

[0075] Please see Figure 6 , Figure 6 for Figure 3 A magnified view of a section at point A in the middle, from Figure 6 As can be seen, along the radial direction of the protective sleeve 12, the connecting sleeve 123 has a thin-walled structure. When a force is applied to the connecting rod 13 in a direction away from the support base 11, the leak-proof structure 10 can break at the connecting sleeve 123. Please refer to [link to relevant documentation]. Figure 4 The first body 121 is connected to the support base 11, and the second body 122 forms a protective sleeve 124 after breakage.

[0076] In one example, the thickness of the connecting sleeve 123 along the radial direction of the protective sleeve 12 ranges from 0.1 to 2 mm. For example, the thickness of the connecting sleeve 123 along the radial direction of the protective sleeve 12 is 0.1 to 0.4 mm, 0.4 to 0.8 mm, 0.8 to 1.2 mm, 1.2 to 1.6 mm, or 1.6 to 2 mm.

[0077] In one example, the first sleeve 121 is tightly fitted with the support base 11, and the first sleeve 121, the connecting sleeve 123, and the second sleeve 122 are integrally formed; or, in other examples, the support base 11 and the protective sleeve 12 are integrally formed.

[0078] In one example, the protective sleeve 12 and the connecting rod 13 are integrally formed.

[0079] In one example, the protective sleeve 12 and the connecting rod 13 are made of silicone or rubber, while the support base 11 is made of plastic. For instance, if the protective sleeve 12 and the connecting rod 13 are made of silicone, then the protective sleeve 12 and the connecting rod 13 are silicone, and if the support base 11 is made of plastic, then the support base 11 is a plastic part. In this example, when the support base 11, the protective sleeve 12, and the connecting rod 13 are integrally molded, they can be manufactured using a two-material injection molding process. A two-material injection molding process refers to injecting two different materials into the same mold to create a part composed of two materials.

[0080] In one example, the first housing 121 is sealed to the liquid storage tank 20; or, in other examples, the first housing 121 is not sealed to the liquid storage tank 20, and the liquid storage tank 20 is sealed to the liquid storage tank 20 by other sealing rings 40.

[0081] In this embodiment of the application, by setting the protective sleeve 12 to include a first sleeve body 121, a second sleeve body 122 and a connecting sleeve 123, not only can a breakable part be formed on the protective sleeve 12, but it also facilitates the fixed connection between the protective sleeve 12 and the support base 11.

[0082] It is worth noting that the above embodiment describes the protective sleeve 12 as including a first sleeve body 121, a second sleeve body 122, and a connecting sleeve 123, with the first sleeve body 121 fitted onto the support base 11. In other embodiments, for example, the protective sleeve 12 may not include the first sleeve body 121, that is, the protective sleeve 12 may only include the second sleeve body 122 and the connecting sleeve 123, with the connecting sleeve 123 connecting the second sleeve body 122 and the support base 11. In this embodiment, the protective sleeve 12 and the support base 11 may be integrally formed; in this embodiment, the protective sleeve 12 and the connecting rod 13 may be made of silicone or rubber, and the support base 11 may be made of plastic or plastic material.

[0083] In one embodiment, please refer to Figure 6 The first housing 121 includes an end portion 1211 and a circumferential portion 1212. The end portion 1211 is located at one end of the support base 11 near the second housing 122 and is connected to the connecting sleeve 123. The circumferential portion 1212 is located on the outer circumferential side of the support base 11, and the end portion 1211 is connected to the circumferential portion 1212. A first annular protrusion 1213 is formed on the outer circumferential side of the circumferential portion 1212, and the first annular protrusion 1213 is sealed to the liquid storage chamber 20. It is worth noting that... Figure 6 The diagram shows the state of the first annular protrusion 1213 when it has not undergone elastic deformation.

[0084] In one example, there is more than one first annular protrusion 1213, such as one, two, or three, etc. See [link to relevant documentation]. Figure 6 This illustrates that the circumferential outer surface of the circumferential portion 1212 has two first annular protrusions 1213.

[0085] In one example, see Figure 6 A groove 1121 is formed on the outer peripheral side of the support base 11, and a protrusion 12121 is formed on the inner peripheral side of the circumferential portion 1212. The protrusion 12121 extends into the groove 1121 on the support base 11 to improve the connection strength between the support base 11 and the first body 121.

[0086] In one example, the groove 1121 on the circumferential side of the support 11 is an annular groove 1121, and an annular protrusion 12121 is formed on the circumferential inner side of the circumferential portion 1212.

[0087] In this embodiment, the first sleeve 121 is provided to include an end face 1211 and a circumferential portion 1212, so as to facilitate the stable connection of the first sleeve 121 to the support base 11; the circumferential outer side of the circumferential portion 1212 is provided to form a first annular protrusion 1213, which can be used for sealing the support base 11 and the liquid storage tank 20.

[0088] In one embodiment, please refer to Figure 3 The second sleeve 122 includes an upper sleeve portion 1221 and a lower sleeve portion 1222. One end of the upper sleeve portion 1221 is connected to the lower sleeve portion 1222, and the lower sleeve portion 1222 is connected to the connecting sleeve 123. The outer diameter of the lower sleeve portion 1222 is larger than the outer diameter of the upper sleeve portion 1221. Please refer to [link / reference]. Figure 8 and Figure 9 This is a schematic diagram of the anti-leakage structure 10 provided in the embodiments of this application. Figure 8 and Figure 9 The upper sleeve part 1221 and the lower sleeve part 1222 are shown in the diagram.

[0089] Please see Figure 3 The inner side of the lower sleeve 1222 is provided with a second annular protrusion 1223 that seals with the atomizing core assembly 30, and the outer side of the upper sleeve 1221 is provided with a third annular protrusion 1224 for sealing with the liquid storage chamber 20.

[0090] In one example, there is more than one second annular protrusion 1223, such as one, two, or three, etc. See [link to relevant documentation]. Figure 5 This illustrates that the inner circumferential surface of the lower sleeve 1222 has two second annular protrusions 1223.

[0091] In one example, there is more than one third annular protrusion 1224; for example, there may be one, two, or three third annular protrusions 1224, etc. Please refer to [link to relevant documentation]. Figure 5 This illustrates that the outer circumferential surface of the upper sleeve 1221 has two third annular protrusions 1224.

[0092] In one example, the first sleeve 121 and the connecting sleeve 123 are made of elastic material, while the upper sleeve portion 1221 and the lower sleeve portion 1222 are made of non-elastic material. For example, the first sleeve 121 and the connecting sleeve 123 are made of silicone or rubber, the upper sleeve portion 1221 and the lower sleeve portion 1222 are made of plastic or plastic material, and the second annular protrusion 1223 is made of silicone or rubber.

[0093] In one example, see Figure 3 The shapes of the internal cavities of the upper sleeve 1221 and the lower sleeve 1222 are matched with the shape of the atomizing core assembly 30.

[0094] In one example, see Figure 4 The liquid storage tank 20 includes a liquid storage tank body 21 and a suction nozzle 22. One end of the suction nozzle 22 extends into the liquid storage tank body 21 and the two are connected. For example, the liquid storage tank body 21 and the suction nozzle 22 can be integrally formed. The end of the suction nozzle 22 located outside the liquid storage tank body 21 forms a suction opening 221. One end of the upper sleeve 1221 extends into the suction nozzle 22 and is sealed to the inner side of the suction nozzle 22 through a third annular protrusion 1224.

[0095] In one example, see Figure 4 When the second set of bodies 122 is located at the target position, that is... Figure 4 When the position shown is such that the end face between the upper sleeve portion 1221 and the lower sleeve portion 1222 is close to or in contact with the inner end face of the suction nozzle portion 22.

[0096] In this embodiment, the second sleeve 122 is configured to include an upper sleeve portion 1221 and a lower sleeve portion 1222, with the outer diameter of the lower sleeve portion 1222 being larger than the outer diameter of the upper sleeve portion 1221. This allows the upper sleeve portion 1221 to fit the shape of the liquid storage tank 20 and be inserted into the nozzle portion 22 of the liquid storage tank 20. The second annular protrusion 1223 and the third annular protrusion 1224 are provided to ensure a sealed fit between the second sleeve 122 and the atomizing core assembly and the nozzle portion 22 of the liquid storage tank 20.

[0097] In one embodiment, please refer to Figure 7 , Figure 7 for Figure 4 The enlarged view at point B shows that the protective sleeve 12 has an easily cuttable portion 1225, which can be used to separate the connecting rod 13 from the protective sleeve 12.

[0098] In one example, see Figure 7 A cutting portion 23 is formed on the inner side of the liquid storage tank 20. When the protective sleeve 124 is in the target position after breakage and a force is applied to the connecting rod 13 in the direction away from the support base 11, the connection position between the protective sleeve 12 and the connecting rod 13 (i.e., the easily cut portion 1225) can be cut off by the cutting portion 23. In other examples, when the protective sleeve 124 is in the target position after breakage, the easily cut portion 1225 can be cut with the aid of a tool to separate the connecting rod 13 from the protective sleeve 12.

[0099] In one example, see Figure 7 The easily cut portion 1225 is connected to the outer peripheral side of the connecting rod 13, and the thickness of the connecting rod 13 connected to the easily cut portion 1225 along the axial direction of the connecting rod 13 is less than a set thickness value; or, in other examples, a thin sheet layer is formed on the end face of the protective sleeve 12, and one end of the connecting rod 13 is connected to the thin sheet layer, and the connecting rod 13 can be separated from the protective sleeve 12 by cutting the thin sheet layer.

[0100] In this embodiment, by providing an easily cuttable portion 1225 on the protective sleeve 12, the connection strength of the easily cut portion on the protective sleeve 12 is less than the connection strength between the connecting rod 13 and the protective sleeve 12. At the same time, when the protective sleeve 124 is in the target position after breakage, the easily cuttable portion 1225 can be cut to separate the connecting rod 13 from the protective sleeve 12, so that the atomizer 100 can be used normally.

[0101] In one embodiment, please refer to Figure 7 The section where one end of the connecting rod 13 is inserted into the protective sleeve 12 and the connecting rod 13 is located inside the protective sleeve 12 is called the mating section 131. A first region and a second region are formed on the mating section 131. The first region and the second region are arranged sequentially along the direction in which the connecting rod 13 extends into the protective sleeve 12. The first region is connected to the inner side of the protective sleeve 12, and there is a gap 14 between the second region and the inner side of the protective sleeve 12. The part of the protective sleeve 12 that is connected to the first region forms an easily cuttable part 1225.

[0102] Please see Figure 7 The diagram shows that the cutting part 23 extends into the gap 14 between the mating section 131 and the protective sleeve 12. When the protective sleeve 124 is in the target position after breakage, the cutting part 23 extends into the gap 14 between the mating section 131 and the protective sleeve 12. At this time, when force is applied to the connecting rod 13 in the direction away from the support seat 11, the easily cut part 1225 can be cut through the cutting part 23.

[0103] In one example, the thickness of the connecting rod 13 where it connects to the first region along the axial direction of the connecting rod 13 is less than a set thickness value, wherein the set thickness value is not less than 1 mm. For example, the thickness of the connecting rod 13 where it connects to the first region along the axial direction of the connecting rod 13 is 1 to 1.5 mm, 1.5 to 2 mm, or 2.5 to 3 mm, etc.

[0104] The side of the protective sleeve 12 opposite to the second area of ​​the mating section 131 is the mating side 1226. Please refer to [link / reference]. Figure 7 The diagram illustrates the mating side 1226. In one example, the mating side 1226 is flared, meaning that along the direction from the first region to the second region, the mating side 1226 is inclined away from the central axis of the connecting rod 13 so as to match the shape of the cutting part 23 so that the cutting part 23 extends into the gap 14 between the mating section 131 and the protective sleeve 12.

[0105] In this embodiment, by setting a gap 14 between the second region of the mating section 131 and the inner side of the protective sleeve 12, the cutting part 23 can easily extend into the gap 14 to cut the part of the protective sleeve 12 that is connected to the first region.

[0106] In one embodiment, please refer to Figure 7 The cutting section 23 includes a first cutting surface 232 and a second cutting surface 233, which are connected to form a cutting end 231. The first cutting surface 232 is closer to the connecting rod 13 than the second cutting surface 233. From the direction closer to the cutting end 231 to the direction away from the cutting end 231, the second cutting surface 233 is inclined away from the connecting rod 13. Please refer to [link / reference]. Figure 7 When the protective sleeve 124 is in the target position after the breakage, the cutting end 231 of the cutting part 23 extends into the gap 14 between the mating section 131 and the protective sleeve 12. At this time, when force is applied to the connecting rod 13 in the direction away from the support seat 11, the connection between the protective sleeve 12 and the connecting rod 13 can be cut off through the cutting end 231 of the cutting part 23.

[0107] In one example, see Figure 5 The liquid storage tank 20 includes a liquid storage tank body 21 and a suction nozzle 22. One end of the suction nozzle 22 extends into and connects the liquid storage tank body 21. The end of the suction nozzle 22 located outside the liquid storage tank body 21 forms a suction nozzle opening 221. A cutting portion 23 is formed on the inner side of the suction nozzle 22.

[0108] In one example, the cutting portion 23 is annular; in other embodiments, the cutting portion 23 may be multiple and the multiple cutting portions 23 may be evenly spaced along the circumferential direction of the inner side surface of the suction nozzle portion 22.

[0109] In this embodiment of the application, by providing the cutting part 23 including the first cutting surface 232 and the second cutting surface 233, a cutting end 231 can be formed on the cutting part 23, which is convenient for cutting off the connection between the protective sleeve 12 and the connecting rod 13.

[0110] In one embodiment, please refer to Figure 10 The support base 11 includes a first base portion 111, a second base portion 112, and a base connecting plate 113. The first base portion 111 and the second base portion 112 are spaced apart along the distribution direction of the support base 11 and the protective sleeve 12. There is one or more base connecting plates 113, and the base connecting plates 113 connect the first base portion 111 and the second base portion 112.

Figure 8 and Figure 9 This illustrates that the first body 121 is fitted onto the second body part 112, and the first body part 111 is provided with a body air inlet 114.

[0111] In one instance, please see Figure 10 A first sealing ring groove 1114 is provided on the first seat body 111, and a sealing ring 40 is installed inside the first seat body 111. That is, a sealing ring 40 is provided between the first seat body 111 and the liquid storage tank 20 to achieve a sealed fit between the first seat body 111 and the liquid storage tank 20.

[0112] In one example, the first housing portion 111 is sealed to the atomizing core assembly 30 by a sealing ring 40, and / or the second housing portion 112 is sealed to the atomizing core assembly 30 by a sealing ring 40.

[0113] In one example, see Figure 10 An air intake boss 1112 is formed on the side of the first seat body 111 facing the second seat body 112, and the seat body air intake hole 114 passes through the air intake boss 1112.

[0114] In one example, one or more air intake protrusions 1112 are formed on the side of the first seat portion 111 facing the second seat portion 112. When there are two or more air intake protrusions 1112, the air intake protrusions 1112 are evenly spaced along the circumferential direction of the first seat portion 111, and the seat air intake holes 114 pass through the corresponding air intake protrusions 1112 respectively.

[0115] In one example, see Figure 8 The support base 11 has a latch 1131 formed on it. Please refer to [link / reference]. Figure 11 A slot 212 is provided on the inner side of the liquid storage tank 20, and the support base 11 is snapped onto the liquid storage tank 20 by the buckle 1131 located in the slot 212.

When the support base 11 is installed on the liquid storage tank 20, the positioning boss 1111 is located in the positioning hole 211. In this example, the positioning boss 1111 cooperates with the positioning hole 211 to facilitate the positioning and installation of the support base 11 and the liquid storage tank 20.

[0119] In one example, see Figure 9 A stepped surface 1113 is formed on the first body part 111, and a positioning boss 1111 is provided on the stepped surface 1113.

[0120] In one example, see Figure 9 Two positioning bosses 1111 are provided on the stepped surface 1113 of the first body 111. The two positioning bosses 1111 are arranged opposite to each other and are respectively inserted into the positioning holes 211 on the liquid storage tank 20.

[0121] In this embodiment of the application, by setting the support base 11 to include a first base part 111, a second base part 112 and a base connecting plate 113, the support base 11 can not only support the atomizing core assembly 30, but also facilitate the fixing of the protective sleeve 12 on the support base 11.

[0122] In one embodiment, please refer to Figure 4 The support base 11 is provided with an injection hole 115, which is connected to the end opening 12111 on the protective sleeve 12. A plug 50 is provided inside the injection hole 115. Please refer to Figure 4 The first body 121 has an end opening 12111 on its end face 1211, which is connected to the injection hole 115.

[0123] In this embodiment of the application, the aerosol matrix can be injected into the placement cavity 60 through the injection hole 115 and the end opening 12111. After the aerosol matrix in the placement cavity 60 is injected, the plug body 50 is inserted into the injection hole 115 to seal the aerosol matrix in the placement cavity 60.

[0124] In one embodiment, please refer to Figure 2The atomizer core assembly 30 includes an atomizer core 31 and an atomizer base 32, with the atomizer core 31 disposed at one end of the atomizer base 32.
