[0058] This embodiment provides an atomizer 100, including an atomizer body and a sealing plug 1. Figure 1 and Figure 4 , shows a schematic diagram of the appearance of the atomizer 100, wherein: Figure 1 The sealing plug 1 is shown installed on the atomizer body. Figure 4 In the figure, the sealing plug 1 is not shown on the atomizer body.

[0059] A through-flow channel 6 is formed in the atomizer body. Figure 5 , Figure 5 is a cross-sectional schematic diagram of the atomizer body, Figure 5 The airflow channel 6 is schematically shown in the figure, and the airflow channel 6 connects the two ends of the atomizer body. The airflow enters through one end of the airflow channel 6 and can be discharged through the other end of the airflow channel 6.

[0060] See also Figure 3 , Figure 3 for Figure 2 AA section view, combined with Figure 3 and Figure 5 The two sealing plugs 1 are respectively inserted into the airflow channel 6 through the two ends of the airflow channel 6, and the sealing plugs 1 are sealed with the atomizer body. When the two sealing plugs 1 are installed in the atomizer body, the airflow channel 6 is sealed with gas with a certain air pressure.

[0061] When the sealing plug 1 is assembled on the atomizer body, in one scenario, one sealing plug 1 can be inserted into the airflow channel 6, and then another sealing plug 1 can be inserted from the other end of the airflow channel 6. During the gradual insertion process of the latter sealing plug 1, the gas in the airflow channel 6 will be squeezed. For example, see Figure 3 The two sealing plugs 1 are respectively a first sealing plug 14 and a second sealing plug 15. The second sealing plug 15 is inserted into the airflow channel 6 from the bottom of the atomizer body, and then the first sealing plug 14 is inserted into the airflow channel 6 from the top of the atomizer body. As the first sealing plug 14 is inserted, the first sealing plug 14 will squeeze the gas in the airflow channel 6. When the length of the first sealing plug 14 is longer, the first sealing plug 14 occupies more space in the airflow channel 6, thereby making the air pressure in the airflow channel 6 greater.

[0062] When the sealing plug 1 is assembled on the atomizer body, in another scenario, two sealing plugs 1 can be assembled on the atomizer body at the same time. At this time, the two sealing plugs 1 squeeze the gas in the airflow channel 6 at the same time during the process of being inserted into the airflow channel 6. The lengths of the two sealing plugs 1 inserted into the airflow channel 6 will affect the air pressure in the airflow channel 6.

[0063] In this embodiment, a liquid storage tank 5 is formed in the atomizer body, and the liquid storage tank 5 contains an aerosol matrix. Figure 3 and Figure 5 , showing the liquid storage tank 5. When the atomizer 100 leaves the factory, the liquid storage tank 5 is usually not completely filled with aerosol matrix, but a certain amount of air remains.

[0064] The two sealing plugs 1 are both in sealing cooperation with the nebulizer body, which can prevent the aerosol matrix from leaking out, that is, prevent the aerosol matrix from overflowing out of the nebulizer body through the air flow channel 6.

[0065] In addition, in order to improve the sealing effect of the aerosol matrix, the present embodiment designs the air pressure difference between the air flow channel 6 and the liquid storage tank 5 to be within the design threshold, that is, by setting a certain air pressure in the air flow channel 6, leakage of the aerosol matrix can be further prevented.

[0066] Specifically, for example, when the air pressure in the liquid storage tank 5 is P1 and the air pressure in the air flow channel 6 is P2, if the air pressure P2 in the air flow channel 6 is not less than the air pressure P1 in the liquid storage tank 5, under the action of the air pressure, the aerosol matrix in the liquid storage tank 5 is not easy to flow to the air flow channel 6, thereby preventing the aerosol matrix from overflowing out of the atomizer body through the air flow channel 6. As described above, by increasing the length of the sealing plug 1 extending into the air flow channel 6, the space occupied by the sealing plug 1 in the air flow channel 6 can be increased, thereby increasing the air pressure in the air flow channel 6, that is, by increasing the length of the sealing plug 1, the effect of preventing the aerosol matrix from overflowing can be achieved.

[0067] In this embodiment, the air pressure difference between the air flow channel 6 and the liquid storage tank 5 is within the design threshold. It can be understood that the air pressure in the air flow channel 6 is related to the air pressure in the liquid storage tank 5. For example, in one example, the air pressure in the air flow channel 6 can be set to be greater than the air pressure in the liquid storage tank 5; in another example, the air pressure in the air flow channel 6 can be set to be slightly smaller than the air pressure in the liquid storage tank 5; in another example, the air pressure in the air flow channel 6 can be set to be equal to the air pressure in the liquid storage tank 5.

[0068] When the air pressure in the air flow channel 6 is slightly lower than the air pressure in the liquid storage tank 5 , compared with the prior art, it is still possible to further prevent the aerosol matrix from leaking out under the action of the air pressure in the air flow channel 6 .

[0069] When the air pressure in the air flow channel 6 is greater than the air pressure in the liquid storage tank 5, it is preferred that the air pressure in the air flow channel 6 is slightly greater than the air pressure in the liquid storage tank 5. If the air pressure in the air flow channel 6 is too high, the gas in the air flow channel 6 may be pressed into the liquid storage tank 5.

[0070] It should also be noted that after the atomizer 100 leaves the factory, the sealing plug 1 is assembled on the atomizer body; when the consumer uses the atomizer 100, the two sealing plugs 1 need to be removed from the atomizer body.

[0071] In the present embodiment, by increasing the length of the sealing plug 1 extending into the airflow channel 6, the space occupied by the sealing plug 1 in the airflow channel 6 can be increased, and then the air pressure in the airflow channel 6 can be increased, so that the air pressure difference between the airflow channel 6 and the liquid storage tank 5 is within the design threshold. That is, in the present embodiment, not only can the sealing plug 1 and the nebulizer body be sealed to prevent the aerosol matrix from leaking out, but under the action of a certain air pressure in the airflow channel 6, the aerosol matrix can be further prevented from leaking out.

[0072] In one embodiment, the sealing plug 1 includes a sealing plug body 11 and a sealing rib 12. The sealing rib 12 is arranged along the circumference of the sealing plug body 11. Figure 6 and Figure 7 , it is shown that a sealing rib 12 is provided on the sealing plug body 11. The sealing rib 12 is annular, and when the sealing plug 1 is inserted into the air flow channel 6, the sealing rib 12 is pressed against the inner side of the air flow channel 6, and the sealing rib 12 is elastically deformed to achieve sealing cooperation between the sealing plug 1 and the atomizer body.

[0073] The two opposite ends of the sealing plug body 11 are respectively a first end 111 and a second end 112. Figure 8 and Fig.10 , illustrating the second end 112 of the sealing plug body 11 , which is inserted into the air flow channel 6 .

[0074] When there are more than two sealing ribs 12, the sealing ribs 12 are arranged in sequence along the direction from the first end 111 to the second end 112. Figure 6-Figure 7 , illustrating the sealing ribs 12 that are arranged in sequence and at intervals along the axial direction of the sealing plug body 11.

[0075] There are more than two sealing ribs 12, for example, two, three or four sealing ribs 12 are arranged on the sealing plug 1, see Figure 6 ,exist Figure 6 In the example of FIG. 1 , four sealing ribs 12 are provided on the sealing plug 1. Figure 7 ,exist Figure 7 In the example shown in FIG. 1 , two sealing ribs 12 are provided on the sealing plug 1 .

[0076] In the two sealing plugs 1, at least one sealing plug 1 is provided with a venting structure 121 on a portion of the sealing rib 12 thereon, and the venting structure 121 is used to connect the two sides of the sealing rib 12 along the direction of the air flow channel 6. Figure 6-Figure 7 , showing the degassing structure 121. In one example, one of the two sealing plugs 1 has a degassing structure 121 disposed on a portion of the sealing ribs 12 thereon; in another example, a portion of the sealing ribs 12 of both sealing plugs 1 is provided with a degassing structure 121.

[0077] When the air release structure 121 is provided on part of the sealing ribs 12 on one of the two sealing plugs 1, at this time, the number of the sealing ribs 12 on the sealing plug 1 not provided with the air release structure 121 can be set to be more than one.

[0078] In the same sealing plug 1, the sealing rib 12 with the air release structure 121 is located on the side of all the sealing ribs 12 without the air release structure 121 close to the second end 112. Specifically, the sealing rib 12 with the air release structure 121 is called an air release sealing rib, and the sealing rib 12 without the air release structure 121 is called a non-air release sealing rib. The number of air release sealing ribs is more than one, and the number of non-air release sealing ribs is more than one. Each air release sealing rib is arranged on the side of all non-air release sealing ribs close to the second end 112 of the sealing plug body 11. The non-air release sealing rib is used to prevent the air in the air flow channel 6 from flowing out of the atomizer body.

[0079] See also Figure 6 ,exist Figure 6 In the example, four sealing ribs 12 are provided on the sealing plug 1, three of which are provided with air release structures 121, one of which is not provided with the air release structure 121, and the sealing rib 12 without the air release structure 121 is close to the first end 111.

[0080] See also Figure 7 ,exist Figure 7 In the example, two sealing ribs 12 are provided on the sealing plug 1, one of the sealing ribs 12 is provided with an air release structure 121, and the other sealing rib 12 is not provided with the air release structure 121, the sealing rib 12 without the air release structure 121 is close to the first end 111, and the sealing rib 12 with the air release structure 121 is close to the second end 112.

[0081] Regarding the air release structure 121, the air release structure 121 is used to connect the two sides of the sealing rib 12 along the direction of the air flow channel 6. Specifically, when the sealing plug 1 is assembled on the atomizer body, if the sealing plug 1 squeezes the gas in the air flow channel 6, the gas can flow toward the first end 111 of the sealing plug body 11 through the air release structure 121 on the sealing rib 12, thereby achieving the effect of pressure relief.

[0082] For example, in one scenario, see Figure 3The two sealing plugs 1 are respectively a first sealing plug 14 and a second sealing plug 15, and part of the sealing ribs 12 on the first sealing plug 14 and the second sealing plug 15 are provided with an air release structure 121. The second sealing plug 15 is inserted into the air flow channel 6 from the bottom of the atomizer body, and then the first sealing plug 14 is inserted into the air flow channel 6 from the top of the atomizer body. As the first sealing plug 14 is inserted, the first sealing plug 14 will squeeze the gas in the air flow channel 6, and the air pressure in the air flow channel 6 will increase. The squeezed gas in the air flow channel 6 can flow toward the first end 111 of the first sealing plug 14 through the air release structure 121 on the first sealing plug 14, and flow toward the first end 111 of the second sealing plug 15 through the air release structure 121 on the second sealing plug 15, so that part of the gas in the air flow channel 6 is The air vent 121 is filled between the first sealing plug 14 and the inner wall of the airflow channel 6, and between the second sealing plug 15 and the inner wall of the airflow channel 6, so as to achieve the effect of pressure relief and prevent the air pressure in the airflow channel 6 from being too high; the sealing rib 12 without an air release structure 121 on the first sealing plug 14 prevents the air in the airflow channel 6 from flowing out of the atomizer body, and the sealing rib 12 without an air release structure 121 on the second sealing plug 15 prevents the air in the airflow channel 6 from flowing out of the atomizer body, so that the first sealing plug 14 and the second sealing plug 15 are assembled on the atomizer body, and gas with a certain air pressure is sealed in the airflow channel 6.

[0083] In this embodiment, by providing an air release structure 121 on a portion of the sealing rib 12 on at least one of the two sealing plugs 1, the pressure relief effect can be achieved to prevent the air pressure in the air flow channel 6 from being too high, thereby preventing the air pressure in the air flow channel 6 from being too high and squeezing the aerosol matrix in the liquid storage tank 5.

[0084] For the sealing rib 12 provided with the air release structure 121, in one embodiment, more than one air release structure 121 is provided on the sealing rib 12. The sealing rib 12 provided with the air release structure 121 is called an air release sealing rib, and one, two, three, four, etc. air release structures 121 may be provided on the air release sealing rib. Figure 6 and Figure 7 ,exist Figure 6 and Figure 7 In the example shown in FIG. 1 , an air release structure 121 is provided on each sealing rib 12 .

[0085] Regarding the air release structure 121, in one embodiment, the air release structure 121 is a through hole provided on the sealing rib 12; or, in another embodiment, see Figure 6 and Figure 7 The air release structure 121 is a notch provided on the sealing rib 12 .

[0086] Regarding the gap, in one specific example, a gap is formed by breaking the annular sealing rib 12 to form the air release structure 121. In another specific example, a portion of the sealing rib 12 is cut to form the gap, and the sealing rib 12 still forms a closed loop after the gap is set.

[0087] In one example, see Figure 6 In the same sealing plug 1, the air release structures 121 on each sealing rib 12 are located on the same side of the sealing plug body 11; in another example, in the same sealing plug 1, the air release structures 121 on each sealing rib 12 are located on different sides of the sealing plug body 11; in another example, in the same sealing plug 1, the air release structures 121 on some sealing ribs 12 are located on different sides of the sealing plug body 11 on other sealing ribs 12.

[0088] See also Fig. 9 and Fig.11 , Fig. 9 for Figure 8 A partial enlarged view of point A in the middle. Fig.11 for Fig.10 A partial enlarged view of point B in the middle. Fig. 9 and Fig.11 The figure shows the deflation structure 121. There is a gap between the deflation structure 121 and the inner side of the airflow channel 6, or the deflation structure 121 contacts the inner side of the airflow channel 6 but does not squeeze it. When the air pressure in the airflow channel 6 is too high, the deflation structure 121 connects the two sides of the sealing rib 12 along the airflow channel 6 to achieve pressure relief.

[0089] In this embodiment, a notch is provided on the sealing rib 12 to form an air release structure 121 . The air release structure 121 has a simple structure and is easy to process.

[0090] In one embodiment, see Figure 3 , Figure 6 and Figure 7 The sealing plug 1 further includes a limiting protrusion 13, which is arranged on the circumferential side of the sealing plug body 11 and close to the first end 111, and the limiting protrusion 13 contacts the end surface of the atomizer body.

[0091] See Figure Figure 6 and Figure 7 , showing the limiting protrusion 13, the limiting protrusion 13 is away from the second end 112 of the sealing plug body 11; see Figure 3 , indicating that the limiting protrusion 13 of the first sealing plug 14 is in contact with the top end surface of the atomizer body, and the limiting protrusion 13 of the second sealing plug 15 is in contact with the bottom end surface of the atomizer body.

[0092] In this embodiment, a limiting protrusion 13 is provided to limit the insertion depth of the sealing plug 1 into the air flow channel 6, thereby facilitating the disassembly and assembly of the sealing plug 1 and the atomizer body.

[0093] In one embodiment, the sealing plug 1 is made of silicone.

[0094] Regarding the atomizer body, in one embodiment, the atomizer body includes a cup body assembly 2 and an atomizer assembly 3, and the atomizer assembly 3 is arranged in the cup body assembly 2, see Figure 3 , illustrating the cup body assembly 2 and the atomization assembly 3.

[0095] See also Figure 5 The cup body assembly 2 is formed with a first channel 2113 and a second channel 223, and the atomizing channel 4 is formed in the atomizing assembly 3. The first channel 2113 and the second channel 223 are respectively connected to the ends of the corresponding sides of the atomizing channel 4. The first channel 2113, the second channel 223 and the atomizing channel 4 form an air flow channel 6. A liquid storage tank 5 is formed between the cup body assembly 2 and the atomizing assembly 3. See Figure 5 , indicating the liquid storage tank 5.

[0096] The liquid storage tank 5 contains an aerosol matrix. When the atomizer assembly 3 is in working condition, the atomizer assembly 3 can heat the aerosol matrix infiltrated into the atomizer assembly 3 to evaporate it. When airflow flows in the airflow channel 6, the evaporated aerosol forms mist under the condensation of the airflow, and the mist flows out of the airflow channel 6 along with the airflow.

[0097] In one embodiment, the sealing plug 1 inserted into the first channel 2113 is the first sealing plug 14, and one end of the first channel 2113 is formed with an air inlet 2114 on the cup body assembly 2. Figure 3 and Figure 5 , indicating that the first sealing plug 14 is inserted into the first channel 2113. Figure 5 , illustrating the air inlet 2114, that is, the first sealing plug 14 is inserted into the atomizer body from the air inlet 2114 side of the atomizer body.

[0098] See also Figure 3 and Figure 5 The atomizer assembly 3 includes a connecting portion 311 , which is inserted into the first channel 2113 . The first sealing plug 14 is inserted into the connecting portion 311 and then continues to be inserted into the atomizer assembly 3 .

[0099] The connecting portion 311 is sealed with the first channel 2113, and the interior of the connecting portion 311 is connected to the first channel 2113. For the length of the first sealing plug 14, see Figure 3 After the first sealing plug 14 is inserted into the connecting portion 311 , it continues to be inserted into the atomizing body 31 .

[0100] In combination with the structural characteristics of the atomizer body, since the sealing plug 1 inserted through the air intake port 2114 of the atomizer body can continue to be inserted into the atomizer assembly 3, the main consideration can be to increase the length of the first sealing plug 14 and increase the space occupied by the first sealing plug 14 in the air flow channel 6, so that the air pressure difference between the air flow channel 6 and the liquid storage tank 5 is within the design threshold.

[0101] In this embodiment, the first sealing plug 14 is inserted into the connecting portion 311 and then further inserted into the atomizing assembly 3, so as to achieve that the air pressure difference between the air flow channel 6 and the liquid storage tank 5 is within the design threshold.

[0102] In one embodiment, see Figure 3 and Fig.12 The atomizer assembly 3 includes an atomizer body 31 and an atomizer seat 32 . The atomizer seat 32 is connected to one end of the atomizer body 31 , and the other end of the atomizer body 31 forms a connecting portion 311 .

[0103] Specifically, see Figure 3 One end of the atomizing body 31 is inserted into the atomizing seat 32 , and the internal flow channel of the atomizing body 31 and the internal flow channel in the atomizing seat 32 together form the atomizing channel 4 of the atomizing assembly 3 .

[0104] In one example, see Figure 5 The atomizing body 31 includes a shell 312, a first layer of oil-absorbing cotton 313, a second layer of oil-absorbing cotton 314 and a heating component 315. A connecting portion 311 is provided at one end of the shell 312. Preferably, the shell 312 and the connecting portion 311 are integrally formed. The first layer of oil-absorbing cotton 313 and the second layer of oil-absorbing cotton 314 are sequentially arranged from the inside to the outside. The heating component 315 is fixed on the second layer of oil-absorbing cotton 314. The heating component 315 is connected to the electrode 9 of the atomizer 100. When the heating component 315 is working, it can heat the aerosol matrix near the heating component 315. The liquid storage tank 5 is formed between the shell 312 and the inner side of the cup body assembly 2. The aerosol matrix of the liquid storage tank 5 can penetrate into the first layer of oil-absorbing cotton 313 and the second layer of oil-absorbing cotton 314 through the shell 312.

[0105] The air pressure in the air flow channel 6 can be increased by increasing the length of the first sealing plug 14 extending into the air flow channel 6 and thereby increasing the space occupied by the first sealing plug 14 , so that the aerosol matrix in the liquid storage tank 5 is not easily able to flow into the atomization channel 4 through the second layer of oil-absorbing cotton 314 .

[0106] See also Figure 3 The cup body assembly 2 includes a nozzle end 211, and the nozzle end 211 includes an inner layer cylinder 2111 and an outer layer cylinder 2112. The inner layer cylinder 2111 is arranged in the outer layer cylinder 2112, and one end of the inner layer cylinder 2111 is connected to one end of the outer layer cylinder 2112 along the circumferential direction. Figure 5, the inner cylinder 2111 forms a first channel 2113.

[0107] See also Figure 3 , the connecting portion 311 is inserted into the inner cylinder 2111, the first sealing plug 14 is inserted into the connecting portion 311 through the inner cylinder 2111, and the first sealing plug 14 is in sealing cooperation with the connecting portion 311 and / or in sealing cooperation with the inner cylinder 2111. That is, the sealing rib 12 on the first sealing plug 14 is only in sealing cooperation with the connecting portion 311, or the sealing rib 12 on the first sealing plug 14 is only in sealing cooperation with the inner cylinder 2111, or some of the sealing ribs 12 on the first sealing plug 14 are in sealing cooperation with the inner cylinder 2111, and the other sealing ribs 12 on the first sealing plug 14 are in sealing cooperation with the connecting portion 311.

[0108] See also Figure 6 ,exist Figure 6 In the example, the sealing rib 12 close to the second end 112 is used to seal with the connecting portion 311 , and the other three sealing ribs 12 are used to seal with the inner cylinder 2111 .

[0109] Preferably, the shape of the sealing plug body 11 of the first sealing plug 14 matches the shape of the connecting portion 311 and the inner cylinder 2111 .

[0110] In this embodiment, the first sealing plug 14 is provided to be in sealing cooperation with the connecting portion 311 and / or the inner cylinder 2111, so as to achieve sealing cooperation between the first sealing plug 14 and the atomizer body.

[0111] Regarding the sealing cooperation between the connection portion 311 and the first channel 2113, in one embodiment, see Figure 5 The free end of the inner cylinder 2111 is provided with a sealing member 7, and the connecting portion 311 is inserted into the outer cylinder 2112 and is sealed with the sealing member 7. Preferably, the sealing member 7 is made of silicone.

[0112] In one embodiment, see Figure 3 and Fig.12 The cup body assembly 2 includes a cup body structure 21 and a seat body 22 , and the seat body 22 is inserted into one end of the cup body structure 21 .

[0113] See also Fig.12 The cup body structure 21 includes a nozzle end 211 and a cylindrical shell 212. The nozzle end 211 is disposed at one end of the cylindrical shell 212 and the two are connected. The seat body 22 is inserted into the cylindrical shell 212 from the end of the cylindrical shell 212 away from the nozzle end 211. The seat body 22 is fixed on the cylindrical shell 212 and sealed with the cylindrical shell 212.

[0114] The atomizing assembly 3 is connected to the seat body 22, see Figure 3The atomizing seat 32 of the atomizing assembly 3 is connected to the seat body 22 .

[0115] See also Figure 5 A second channel 223 is formed on the seat body 22, and the second channel 223 is connected to the bottom of the atomizing assembly 3. Figure 3 , indicating that a sealing plug 1 is installed in the second channel 223.

[0116] The sealing plug 1 disposed in the second channel 223 is referred to as the second sealing plug 15. In combination with the structural features of the cup assembly 2, the length of the second sealing plug 15 is shorter than that of the first sealing plug 14. Considering that the second sealing plug 15 is relatively short, in order to squeeze the gas in the airflow channel 6 through the sealing plug 1, when the sealing plug 1 is assembled on the atomizer body, the second sealing plug 15 is first inserted into the second channel 223 from the bottom of the atomizer body, and then the first sealing plug 14 is inserted into the first channel 2113 from the top of the atomizer body; or, the first sealing plug 14 is inserted into the first channel 2113 and the second sealing plug 15 is inserted into the second channel 223 at the same time.

[0117] In one embodiment, see Fig.13 The seat body 22 includes a seat body main body 221 and a cylinder body 222. The cylinder body 222 is an open structure at one end. A second channel 223 is formed in the cylinder body 222. A plurality of air holes 2221 are arranged on the end surface of the cylinder body 222 away from the open end.

[0118] See also Fig.10 , illustrating the second sealing plug 15 is inserted into the cylinder 222. The length of the cylinder 222 limits the length of the second sealing plug 15.

[0119] In one example, the second end 112 of the second sealing plug 15 is close to an end of the cylinder 222 where the air hole 2221 is provided, so as to increase the length of the second sealing plug 15 as much as possible.

[0120] For the seat body 221, see Fig.13 A receiving cavity 2212 is formed between the seat body 221 and the cylinder 222. Figure 3 The bottom oil-absorbing cotton 8 is located in the accommodating cavity 2212. The seat body 221 is also provided with an electrode plug hole 2211, and the two electrode plug holes 2211 are respectively provided on both sides of the cylinder 222.
