[0012] Furthermore, the base is also provided with two electrode nails, and the heating component is electrically connected to the two electrode nails.

[0013] Furthermore, one end of the auxiliary silicone rubber facing the atomizer core protrudes from the air passage and abuts against the atomizer core, and the other end of the auxiliary silicone rubber extends in a direction away from the shell and protrudes from the shell.

[0014] The present application also provides an assembly method of an atomizer, which is applicable to the assembly of the above-mentioned atomizer, and the method comprises the following steps:

[0015] Insert the auxiliary silicone into the airway until one end of the auxiliary silicone protrudes from the shell, and pull the end of the auxiliary silicone protruding from the shell until the auxiliary silicone reaches the installation position, so that the auxiliary silicone seals the airway, wherein when the auxiliary silicone reaches the installation position, one end of the auxiliary silicone protrudes from the airway and abuts against the airway;

[0016] Inject oil into the oil storage tank through the opening until the oil level is flush with one end of the auxiliary silicone;

[0017] Insert the atomizer core into the opening, with one end of the atomizer core abutting against the airway, wherein an air intake channel connected to the oil storage tank and the outside air is provided in the atomizer core.

[0033] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0034] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0035] Please see Figure 3-Figure 5 The present application provides an atomizer 100, comprising a shell 1, an atomizer core 2, a dustproof end cap 3 and an auxiliary silicone 4. An airway 11 is provided at one end of the shell 1, and an opening 12 is provided at the other end, and the opening 12 is used for oil filling. The atomizer core 2 blocks the opening 12, and one end of the atomizer core 2 is connected to the airway 11, and the other end abuts against the dustproof end cap 3. The inner side wall of the dustproof end cap 3 abuts against the outer periphery of the shell 1, the auxiliary silicone 4 is arranged in the airway 11, and the outer periphery of the auxiliary silicone 4 abuts against the inner wall of the airway 11. An oil storage bin 13 arranged around the airway 11 is provided in the shell 1, and the dustproof end cap 3, the auxiliary silicone 4 and the shell 1 seal the oil storage bin 13.

[0036] The air passage 11 can be formed by the structure of the shell 1 itself, or by an external air pipe. In the present embodiment, the shell 1 is an integrated structure, one end of the shell 1 is recessed inward to form the air passage 11, and the aerosol generated by the atomizer core 2 flows to the outside through the air passage 11. The shell 1 is a hollow structure, and an opening 12 is formed on one end face of the shell 1. The cavity in the shell 1 constitutes an oil storage tank 13. The user can inject an aerosol substrate into the oil storage tank 13 from the opening 12. The aerosol substrate is an aerosol substrate in the form of oil liquid, so that the atomizer core 2 can generate aerosol.

[0037] After the air passage 11 is sealed by the auxiliary silicone 4, the oil is injected into the oil storage tank 13 from the opening 12 opened on the shell 1, which avoids the oil being injected into the air passage 11 due to misoperation during oil injection, causing leakage, and reduces the difficulty of oil injection. After the oil injection is completed, the opening 12 is blocked by the atomizer core 2, the atomizer core 2 is sealed by the dustproof end cover 3, and the air passage 11 is sealed by the auxiliary silicone 4. The oil storage tank 13 is sealed in combination with the integrated structure of the shell 1, which effectively prevents the oil from flowing out of the air passage 11 during transportation and causing leakage, and at the same time prevents dust and other debris from entering the oil storage tank 13 and affecting the quality of the oil.

[0038] Furthermore, one end of the auxiliary silica gel 4 facing the atomizer core 2 protrudes from the air passage 11 and abuts against the atomizer core 2 , and the other end of the auxiliary silica gel 4 extends in a direction away from the shell 1 and protrudes from the shell 1 .

[0039] In this embodiment, one end of the auxiliary silica gel 4 facing the atomizer core 2 extends radially outward to form a mounting portion 41, and the mounting portion 41 protrudes from the air passage 11. It can be understood that the mounting portion 41 is formed by one end of the auxiliary silica gel 4 extending radially outward, so a step is formed at the connection between the mounting portion 41 and other parts of the auxiliary silica gel 4, and the step abuts against the air passage 11, which is used to limit the auxiliary silica gel 4 during installation.

[0040] In the prior art, when filling the oil storage tank 13 with oil, in order to prevent oil leakage, the highest position of the oil level can only reach the top of the airway 11 (such as Figure 1 In the present embodiment, it can be understood that the auxiliary silicone 4 seals the airway 11, and the mounting portion 41 of the auxiliary silicone 4 protrudes from the airway 11, so when the oil storage tank 13 is filled with oil, the highest position of the oil level can rise to the top of the mounting portion 41, so that the atomizer 100 has a larger oil storage capacity.

[0041] In some feasible embodiments, an extension portion 44 is further provided at one end of the mounting portion 41 close to the atomizer core 2. The diameter of the extension portion 44 is smaller than that of the mounting portion and avoids the heating component 22 mentioned later. It can be understood that the extension portion 44 is added to one end of the mounting portion 41 so that when the oil storage tank 13 is filled with oil, the highest position of the oil level can rise to the top of the extension portion 44 (such as Figure 2 b) to increase the oil storage capacity of the atomizer 100. The extension portion 44 avoids the side where the heating component 22 is located to avoid interference with the installation of the heating component 22.

[0042] The auxiliary silicone 4 has a first butting portion 42 and a second butting portion 43 at one end close to the atomizer core 2 . The first butting portion 42 is arranged on the periphery of the mounting portion 41 . The first butting portion 42 is used to butt and seal with the atomizer core 2 . The second butting portion 43 is used to butt and seal with the airway 11 .

[0043] One end of the auxiliary silicone 4 away from the atomizer core 2 extends in a direction away from the shell 1 and protrudes from the shell 1. It can be understood that when installing the auxiliary silicone 4, the auxiliary silicone 4 can be assembled by pulling outward the end protruding from the shell 1 until the step abuts against the airway 11. While the operation is simple, it can also ensure that the auxiliary silicone 4 is installed in place to ensure the sealing effect of the auxiliary silicone 4 on the airway 11.

[0044] In some feasible embodiments, when installing the auxiliary silica gel 4, a certain distance can be reserved between the mounting portion 41 and the airway 11 to increase the amount of oil injection, while ensuring that the auxiliary silica gel 4 seals the airway 11. Specifically, the position of the auxiliary silica gel 4 during installation is divided into an initial position and a final position, and the second abutting portion 43 can be a two-stage structure. During oil injection, the initial position of the auxiliary silica gel 4 is higher than the final position, so that when the auxiliary silica gel 4 is in the initial position, the liquid level of the oil is higher than the liquid level of the oil when the auxiliary silica gel 4 is in the final position, so that the atomizer 100 has a larger oil storage capacity, and at this time, one section of the second abutting portion 43 seals the airway 11. After the oil injection is completed, the atomizer core 2 is installed in the housing 1, and one end of the atomizer core 2 abuts against the auxiliary silica gel 4. Therefore, during the installation of the atomizer core 2, the atomizer core 2 will push the auxiliary silica gel 4 from the initial position to the final position until the auxiliary silica gel 4 reaches the final position. At this time, both sections of the second abutting portion 43 seal the airway 11 and the installation is completed.

[0045] The atomizer core 2 includes a connector 21 and a heating assembly 22 . The connector 21 is sleeved on the airway 11 and is provided with an air passage 211 communicating with the air of the airway 11 . The heating assembly 22 is disposed in the connector 21 and abuts against the connector 21 .

[0046] The connector 21 is used to separate the airway 11 from the oil storage tank 13 to prevent oil from entering the airway 11. Specifically, the inner wall of the connector 21 is provided with a third abutting portion 212. When the connector 21 is sleeved on the airway 11, the third abutting portion 212 abuts against the outer periphery of the airway 11, thereby realizing a sealed connection between the connector 21 and the airway 11, thereby preventing oil from entering the inside of the airway 11 from the connection between the connector 21 and the airway 11 when the atomizer 100 is used, thereby affecting the user experience. Optionally, the connector 21 is made of silicone material as a whole or the third abutting portion 212 is made of silicone material, thereby realizing a sealed connection between the connector 21 and the airway 11. The connector 21 is provided with an air path channel 211 that passes through the connector 21 along the axis, and the heating component 22 is located in the air path channel 211. When the atomizer 100 is used, the aerosol generated by heating by the heating component 22 can flow into the airway 11 from the air path channel 211.

[0047] In order to facilitate the connection of the atomizer core 2 to the airway 11, the inner wall of the end of the connector 21 close to the airway 11 can be set to a conical surface. Specifically, the diameter of the inner wall of the end of the connector 21 close to the airway 11 gradually increases along the direction of installing the atomizer core 2, so as to facilitate the connector 21 to be sleeved on the airway 11. The end of the connector 21 connected to the airway 11 can also be chamfered to facilitate the connector 21 to align with the airway 11.

[0048] Furthermore, the heating assembly 22 includes an oil guide 221 and a heating element 222. The oil guide 221 abuts against the connecting member 21, the heating element 222 is connected to the oil guide 221, and the heating element 222 is located in the gas path 211. The oil guide 221 has a groove 2211 at one end thereof facing the oil storage tank 13.

[0049] In this embodiment, a through mounting hole is provided on the side wall of the connecting member 21, and the oil guide member 221 is vertically arranged and embedded in the mounting hole. One end of the oil guide member 221 facing the gas path 211 is connected to the heating element 222, and the other end directly contacts the oil in the oil storage tank 13. The oil guide member 21 and the heating assembly 22 are tightly matched to prevent oil from leaking from the connection between the connecting member 21 and the heating assembly 22.

[0050] In a feasible embodiment, the oil guide member 221 can be arranged horizontally, and the two side surfaces of the oil guide member 221 adjacent to the end surface where the heating element 222 is located directly contact the oil in the oil storage tank 13. In another feasible embodiment, the oil guide member 221 can be arranged as a hollow cylinder, and the heating element 222 is arranged on the inner wall of the oil guide member 221, and the internal cavity of the oil guide member 221 constitutes a part of the gas path 211. In this case, an oil inlet hole is arranged at a position corresponding to the oil guide member 221 on the connecting member 21, and the oil contacts the oil guide member through the oil inlet hole, so that the heating element 222 can heat the oil to generate an aerosol.

[0051] In this embodiment, the oil guide member 221 is provided with a groove 2211 at one end facing the oil storage tank 13 to increase the contact area between the oil guide member 221 and the oil, so that the oil guide member 221 can absorb the oil more fully. The heating element 222 is arranged in the gas path 211. When the heating element 222 is powered on, the heating element 222 heats the oil in the oil guide member 221 to generate an aerosol. The oil guide member 221 can be oil-absorbing cotton, porous ceramics or porous glass, etc., the heating element 222 can be a heating wire, a heating net or a heating film layer, etc., and the heating element 222 can be arranged on the end surface of the oil guide member 221 or embedded in the oil guide member 221, which is not limited here.

[0052] In some feasible embodiments, an oil drain hole (not shown) may be provided at the connection between the connector 21 and the air passage 11 to drain the oil entering the atomizer core 2 into the oil storage tank 13. It is understandable that when oil is being filled (the atomizer 100 is in Figure 5 In the state shown in the figure, if the liquid level of the oil is higher than the top of the mounting portion 41 of the auxiliary silicone 4, when the atomizer core 2 is assembled, the oil will enter the inside of the atomizer core 2 from the bottom of the connector 21. At this time, by setting an oil drain hole at the connection between the connector 21 and the airway 11, the oil will flow back into the oil storage tank 13 from the oil drain hole during the process of gradually installing the atomizer core 2 into the shell 1. The oil drain hole can be set on the side of the third abutting portion 212 on the connector 21 away from the heating component 22. In this way, during the assembly of the atomizer core 2, the oil drain hole can maintain the communication between the atomizer core 2 and the liquid storage tank 13, so that the oil in the atomizer core 2 can enter the liquid storage tank 13 from the oil drain hole; when the atomizer core 2 is installed to the preset position in the shell 1, the oil drain hole can contact the airway 11 and be closed by the airway 11, so as to prevent the oil in the oil storage tank 13 from entering the atomizer core 2 from the oil drain hole after assembly.

[0053] The atomizer core 2 further includes a base 23 and an atomizer seat 24 . One end of the connector 21 away from the airway 11 is sleeved on the atomizer seat 24 and abuts against the inner wall of the shell 1 . One end of the base 23 is connected to the atomizer seat 24 and the other end abuts against the shell 1 .

[0054] One end of the connector 21 is tightly in contact with the inner wall of the housing 1, so as to seal and preserve the oil in the oil storage tank 13 and prevent the oil from leaking from the connection between the connector 21 and the housing 1. The atomizer seat 24 is used to support the connector 21 to prevent the connector 21 from being deformed too much and causing oil leakage. The base 23 is used to fix the atomizer seat 24 and block the opening 12. The base 23 and the housing 1 are fixed by snap-fitting. A seal 25 is provided at the connection between the base 23 and the housing 1. The seal 25 can be an O-ring, etc., which is used to enhance the fixing effect between the base 23 and the housing 1 and further seal the oil storage tank 13.

[0055] Further, the base 23 is provided with a liquid collecting tank 231 and oil absorbing cotton 232, the liquid collecting tank 231 is arranged at the position corresponding to the airway 11, and the oil absorbing cotton 232 is arranged on the liquid collecting tank 231. In the present embodiment, the liquid collecting tank 231 is arranged opposite to the airway 11. It can be understood that when the atomizer 100 is in use, the aerosol generated by the atomizing core 2 flows out of the airway 11, and the aerosol may produce condensate on the inner wall of the airway 11 when passing through the airway 11. The condensate will slide along the inner wall of the airway 11 and finally drip onto the base 23, so the base 23 needs to be provided with a liquid collecting tank 231 for collecting the condensate. When the atomizer 100 is in use, a small amount of oil may enter the airway channel 211 and finally drip into the liquid collecting tank 231, so the oil absorbing cotton 232 is arranged on the liquid collecting tank 231 to absorb the leaked oil. When the oil level is higher than the top of the extension 44 (such as Figure 2 When the liquid level reaches b), part of the oil will enter the atomizer core 2, and the oil in the atomizer core 2 can also be absorbed by the oil-absorbing cotton 232. Furthermore, the oil-absorbing cotton 232 can be connected to the heating component 22 through an oil transmission member with a capillary structure, such as an oil transmission member composed of oil-absorbing cotton, and the oil absorbed by the oil-absorbing cotton 232 is transmitted to the heating component 22 through the oil transmission member, so that the leaked oil can be heated by the heating component 22 to generate aerosol, thereby improving the utilization rate of the oil.

[0056] The base 23 is also provided with two electrode nails 233, and the heating component 22 is electrically connected to the two electrode nails 233. When the atomizer 100 is used, the two electrode nails 233 are electrically connected to the power supply device, and then the power supply device supplies power to the heating component 22 to heat the oil to generate an aerosol. The electrode nail 233 is an internally hollow structure. When the atomizer 100 is used, the internal cavity of the electrode nail 233 constitutes a part of the air intake channel and is connected to the air of the airway 11. In some feasible embodiments, an air intake air path is provided in the power supply device, and the air intake air path is connected to the air of the internal cavity of the electrode nail 233. When in use, one end of the power supply device is plugged into the electrode nail 233, and the air passes through the air intake air path and enters the atomizer 100 from the inside of the electrode nail 233, so that the intake air is easily gathered, which can improve the user experience.

[0057] The dustproof end cover 3 is provided with a fourth abutting portion 31. When the dustproof end cover 3 is sleeved on the housing 1, the fourth abutting portion 31 is tightly abutted against the outer periphery of the housing 1 to seal the opening 12. In order to enhance the connection effect between the dustproof end cover 3 and the housing 1 and prevent the dustproof end cover 3 from falling off during transportation, the dustproof end cover 3 is further provided with two fixing columns 32. The two fixing columns 32 are respectively inserted into the two electrode nails 233. The outer peripheries of the two fixing columns 32 are tightly abutted against the inner walls of the two electrode nails 233. While enhancing the connection effect between the dustproof end cover 3 and the housing 1, the two electrode nails 233 are sealed, and the sealing effect of the opening 12 is further enhanced.

[0058] The above-mentioned connecting piece 21 and auxiliary silicone 4 can be made of elastically deformable materials. When assembling the atomizer 100, the auxiliary silicone 4 is inserted into the airway 11, and a certain pulling force is applied to the end of the auxiliary silicone 4 protruding from the shell 1 to move the auxiliary silicone 4 outward until the step of the mounting portion 41 abuts against the airway 11, so as to install the auxiliary silicone 4 in place. When using the atomizer 100, by applying a greater pulling force to the end of the auxiliary silicone 4 protruding from the shell 1, the mounting portion 41 is elastically deformed and then detached from the connecting piece 21 and enters the airway 11, and finally the auxiliary silicone 4 is pulled out, and then the aerosol generated by the heating element can enter the airway 11 from the airway channel 211, and finally flow out to the outside.

[0059] The present application also provides a method for assembling an atomizer, comprising the following steps:

[0060] Step S10, inserting the auxiliary silicone 4 into the airway 11 until one end of the auxiliary silicone 4 protrudes from the housing 1, pulling the end of the auxiliary silicone 4 protruding from the housing 1 until the auxiliary silicone 4 reaches the installation position, so that the auxiliary silicone 4 seals the airway 11; wherein, when the auxiliary silicone 4 reaches the installation position, one end of the auxiliary silicone 4 protrudes from the airway 11 and abuts against the airway 11;

[0061] Step S20, injecting oil into the oil storage tank 13 through the opening 12, and the liquid level of the oil is flush with one end of the auxiliary silica gel 4;

[0062] Step S30, insert the atomizer core 2 into the opening 12, and one end of the atomizer core 2 abuts against the airway 11, wherein the atomizer core 2 is provided with an air intake passage connected to the oil storage tank 13 and the outside air. At this time, the air in the oil storage tank 13 is discharged to the outside after passing through the air intake passage;

[0063] Step S40 , sleeve the dustproof end cover 3 on the housing 1 , wherein the fourth abutting portion 31 is tightly abutted against the outer periphery of the housing 1 , and the fixing column 32 is tightly abutted against the electrode pin 233 , so as to seal the opening 12 and the air inlet passage.

[0064] Specifically, in step S10, a mounting portion 41 and a second abutting portion 43 are provided at one end of the auxiliary silicone 4 close to the atomizer core 2. When the auxiliary silicone 4 is inserted into the air passage 11, the auxiliary silicone 4 abuts against the inner wall of the air passage 11 through the second abutting portion 43 to seal the air passage 11. Then, the auxiliary silicone 4 is pulled out of one end of the housing 1 until the mounting portion 41 abuts against the air passage 11, thereby completing the assembly of the auxiliary silicone 4.

[0065] In step S30, a connector 21 is provided at one end of the atomizer core 2 close to the air passage 11, and an air passage 211 penetrating the connector 21 is provided along the axis of the connector 21, and the air passage 211 is in air communication with the air passage 11. A third abutting portion 212 is provided on the inner side wall of the connector 21, and when the atomizer core 2 is plugged into the housing 1 until the third abutting portion 212 abuts against the outer periphery of the air passage 11, the connector 21 is tightly sleeved on the air passage 11, realizing a sealed connection between the connector 21 and the air passage 11, and preventing oil from entering the interior of the air passage 11 from the connection between the connector 21 and the air passage 11 when the atomizer 100 is used, thereby affecting the user experience.

[0066] When filling oil, the filling is completed when the liquid level of the oil is flush with or slightly higher than one end of the auxiliary silicone 4. When the liquid level of the oil is slightly higher than one end of the auxiliary silicone 4, some of the oil will enter the atomizer core 2. At this time, the oil in the atomizer core 2 can be discharged through the oil discharge hole on the connecting piece 21 and the oil in the atomizer core 2 can be absorbed by the oil absorbing cotton 232 on the base 23.

[0067] The assembly process of the atomizer core 2 is as follows: first, the heating component 22 is embedded in the side wall of the connecting piece 21, with the heating element 222 facing the inside of the connecting piece 21, and then the connecting piece 21 is sleeved on the outer periphery of the atomizer seat 24 until the connecting piece 21 and the atomizer seat 24 are fitted together, and finally, the end of the atomizer seat 24 away from the connecting piece 21 is plugged into the base 23 by means of a snap-fit ​​fixing method, and the assembly of the atomizer core 2 is completed.

[0068] Please see Figure 5 , is a schematic diagram of the gas flow direction of the atomizer 100 when it is installed. The atomizer seat 24 is provided with an air hole (not shown in the figure), and the air path 211, the air hole and the internal cavity of the electrode nail 233 constitute an air inlet channel. When the atomizer core 2 is inserted into the shell 1 and the opening 12 of the shell 1 is blocked, the air in the oil storage tank 13 passes through the heating component 22, the connecting piece 21 and the atomizer seat 24 in sequence, and is finally discharged to the outside from the electrode nail 233.

[0069] The oil filling method provided in the present application, after the air passage 11 is sealed by auxiliary silicone 4, oil is filled into the oil storage tank 13 from the opening 12 opened on the shell 1, which avoids the oil being injected into the air passage 11 due to misoperation during oil filling, causing leakage, and reduces the difficulty of oil filling operation. After the oil filling is completed, the opening 12 is blocked by the atomizer core 2, the atomizer core 2 is sealed by the dustproof end cover 3, and the air passage 11 is sealed by the auxiliary silicone 4, and the oil storage tank 13 is sealed in combination with the integrated structure of the shell 1, which effectively prevents the oil from flowing out of the air passage 11 during transportation and causing leakage, and at the same time prevents dust and other debris from entering the oil and affecting the quality of the oil.

[0070] The present application also provides an aerosol generating device, which uses the above-mentioned atomizer 100. When the aerosol generating device is used, the auxiliary silica gel 4 and the dustproof end cap 3 need to be removed.

[0071] After the airway 11 is sealed by the auxiliary silicone 4, the oil is injected into the oil storage tank 13 from the opening 12 opened on the shell 1, thereby avoiding the injection of oil into the airway 11 due to misoperation during oil injection, causing leakage, and reducing the difficulty of oil injection. A mounting portion 41 is provided at one end of the auxiliary silicone 4, and the other end protrudes from the shell 1. By applying a certain pulling force to the end of the auxiliary silicone 4 protruding from the shell 1 until the mounting portion 41 abuts against the airway 11, the auxiliary silicone 4 can be installed in place, which is easier to operate, and the auxiliary silicone 4 is not easy to fall during transportation, effectively preventing oil from leaking from the airway 11. At the same time, the mounting portion 41 also protrudes from the airway 11. It can be understood that compared with the existing structure in which the liquid level of the oil can only reach the top of the airway 11 during oil injection, the liquid level of the oil in the present application can reach the top of the mounting portion 41 at a higher position during oil injection, so that the atomizer core 2 has a larger oil storage capacity. After the oil filling is completed, the opening 12 is blocked by the atomizer core 2, the atomizer core 2 is sealed by the dustproof end cover 3, and the airway 11 is sealed by the auxiliary silicone 4. Combined with the integrated structure of the shell 1, the oil storage tank 13 is sealed, which effectively prevents the oil from flowing out of the airway 11 during transportation and causing leakage, and at the same time prevents dust and other debris from entering the oil and affecting the quality of the oil.
