[0052] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0053] This application discloses an atomizing device, such as... Figure 1 and Figure 2 As shown, the atomizing device includes an atomizer 200 and an atomizing host 100. The atomizing host 100 works in conjunction with the atomizer 200 to provide power to the atomizer 200. The atomizing host 100 may include a battery 150 to power the atomizer 200, or the atomizing host 100 may be connected to an external power source to indirectly power the atomizer 200. The atomizer 200 may have a liquid storage chamber 400, a liquid guiding component, and an atomizing assembly. Both the liquid guiding component and the atomizing assembly may be arranged within the liquid storage chamber 400, and the liquid guiding component may be fitted over the atomizing assembly, so that the liquid guiding component can guide the atomizing matrix in the liquid storage chamber 400 to the atomizing assembly. The atomizing assembly has an atomizing air passage 220 and a heating element arranged within the atomizing air passage 220; the liquid guiding component can guide the atomizing matrix to the heating element 250, so that the heating element 250, when energized, can atomize the atomizing matrix to form an aerosol.

[0054] In some embodiments, the liquid guiding component may be oil-guiding cotton or polymer cotton, etc., and the heating element 250 may be heating wire or heating mesh, etc.

[0055] In some embodiments, such as Figure 2 As shown, the atomizing host 100 may include: a base 110; a support assembly 120, the support assembly 120 including a support 121 and a sealing member 122, the support 121 being connected to the base 110 and enclosing to form a receiving space 130; the sealing member 122 being disposed within the receiving space 130, the sealing member 122 and the support 121 enclosing to form a collection chamber 123; the support 121 having an air inlet 1211 communicating with the collection chamber 123, the air inlet 1211 being communicating with the atomizing air passage 220 of the atomizer 200; and a circuit board 140, disposed within the receiving space 130 and located outside the collection chamber 123, the circuit board 140 being electrically connected to the atomizer 200.

[0056] In this embodiment, the seal 122 and the bracket 121 enclose a collection chamber 123, which is connected to the atomizing air passage 220 of the atomizer 200 through the air inlet 1211. Thus, any leaked atomizing matrix or condensate from the atomizing air passage 220 can be collected in the independent collection chamber 123 through the air inlet 1211. Since the circuit board 140 is located outside the collection chamber 123, and the collection chamber 123 can collect any leaked atomizing matrix or condensate, it prevents the atomizing matrix or condensate from flowing onto the circuit board 140, effectively ensuring the reliability and stability of the circuit board 140, and consequently ensuring the reliability of the atomizing device.

[0057] In this embodiment, the base 110 serves as the base of the atomizing host 100 and can also function as the base of an atomizing device. Figure 3 and Figure 4 As shown, the bracket 121 may have a first receiving groove 124 with one open end, and the base 110 may have a second receiving groove 112 with one open end. The open end of the bracket 121 is fixedly installed with the open end of the base 110, so that the first receiving groove 124 and the second receiving groove 112 can jointly define the receiving space 130. The internal components of the atomizing host 100 can be installed in the receiving space 130, and the base 110 and the bracket 121 can also protect the internal components in the receiving space 130.

[0058] In some embodiments, one end of the bracket 121 can be mounted and engaged with the base 110, and the other end can be mounted and engaged with the atomizer 200.

[0059] In some embodiments, the bracket 121 and the base 110 can be fixedly connected by means of adhesive or limiting fixation, or they can be detachably connected by means of snap-fit. This application does not specifically limit this aspect.

[0060] In some embodiments, both the seal 122 and the circuit board 140 are arranged within the receiving space 130. The seal 122 can be connected to the bracket 121 and enclose the bracket 121 to form a collection chamber 123. Figures 2 to 5 As shown, the support 121 has an air inlet 1211 at the end opposite to the base 110. The air inlet 1211 is connected to the collection chamber 123, so that the collection chamber 123 can collect the atomizing matrix leaking from the atomizer 200 through the air inlet 1211. The internal components of the atomizer host 100 can be arranged in other positions within the accommodating space 130. That is, in this application, an independent collection chamber 123 is set to store the atomizing matrix leaking from the atomizer 200, thereby preventing the atomizing matrix from contacting and corroding the internal components in the accommodating space 130, such as the circuit board 140.

[0061] In some embodiments, the shape of the air inlet 1211 can be circular, elliptical or square, etc. The shape and size of the air inlet 1211 can be designed with reference to the atomizing air passage 220, but are not specifically limited in this embodiment.

[0062] In this embodiment, the sealing element 122 can be sealed to the bracket 121 by means of adhesion or snap-fit, etc., and this embodiment does not specifically limit the method. The bracket can be a single integrally formed component, or it can be assembled from multiple components, and this embodiment does not specifically limit the method.

[0063] In some embodiments, the circuit board 140 can be directly connected to the base 110 or indirectly connected to the base 110. The circuit board 140 and the seal 122 are spaced apart, and the circuit board 140 and the collection chamber 123 are also spaced apart. This can further reduce the risk of the atomizing matrix flowing to the circuit board 140 and corroding and damaging the circuit board 140, thereby ensuring the reliability and stability of the circuit board 140 and the atomizing host 100, as well as the reliability of the atomizing device.

[0064] In this embodiment, the circuit board 140 may be a printed circuit board (PCB). The circuit board 140 may be snapped onto the base 110 or glued to the base 110. This embodiment does not specifically limit this.

[0065] In some embodiments, the circuit board 140 can be electrically connected to the heating element in the atomizer 200 via pins to enable the heating element to be powered.

[0066] In some embodiments, there may be a gap between the circuit board 140 and the seal 122, or the circuit board 140 and the seal 122 may be separated by other components, etc., which are not specifically limited in this embodiment.

[0067] In some embodiments, the air inlet 1211 may communicate with the atomizing air passage 220 of the atomizer 200, such as... Figure 6 As shown, the atomizer 200 may further include a housing 300, which is connected to the base 110 and encloses to form a receiving cavity; a support assembly 120 may be arranged in the receiving cavity; the side of the support 121 facing away from the base 110 and enclosed with the housing 300 to form a liquid storage chamber 400; the atomizer 200 may be arranged in the liquid storage chamber 400; and the support 121 is provided with a liquid injection hole 1215 spaced apart from the air inlet 1211.

[0068] In this embodiment, the atomizer 200 is arranged inside the liquid storage tank 400 to facilitate the atomization of the atomizing matrix inside the liquid storage tank 400. A liquid injection hole 1215 is provided on the support 121 to facilitate the replenishment of the atomizing matrix into the liquid storage tank 400 through the liquid injection hole 1215, thereby improving the service life of the atomizing device.

[0069] In some embodiments, the atomizing device also includes a plug that can seal the injection port 1215 to ensure the airtightness of the liquid storage chamber 400.

[0070] In some embodiments, the support assembly 120 may further include a liquid reservoir cap 125, which is connected to the side of the support 121 away from the base 110, and the circumferential side of the liquid reservoir cap 125 is sealed to the inner wall of the housing 300, so that the support 121 can be sealed to the housing 300 through the liquid reservoir cap 125. The side of the liquid reservoir cap 125 away from the support 121 can be enclosed with the housing 300 to form a liquid reservoir 400, so that the liquid reservoir 400 has good sealing performance.

[0071] In some embodiments, the liquid storage cap 125 is provided with a vent hole 1251 and a liquid replenishment hole 1252 spaced apart. The vent hole 1251 is connected to the air inlet 1211 and the atomizing air channel 220 respectively, and the liquid replenishment hole 1252 can be connected to the liquid injection hole 1215.

[0072] In some embodiments, the reservoir cap 125 may be a silicone or plastic component to improve the reliability of the sealing connection between the reservoir cap 125 and the housing 300.

[0073] In this embodiment of the application, when a negative pressure is generated in the liquid storage chamber 400 or the atomizing device is in a high or low temperature environment, the air pressure in the liquid storage chamber 400 changes, so that the atomizing matrix in the liquid storage chamber 400 can first enter the atomizing air passage 220, then enter the air inlet 1211 from the vent 1251, and then leak into the collection chamber 123.

[0074] In some embodiments, such as Figure 1 and Figure 2As shown, the atomizer 200 also includes a nozzle 500 and an air-blocking component 600. The nozzle 500 has an air outlet that can be connected to the atomizing air passage. The air-blocking component 600 can block the air outlet on the nozzle 500, which helps to ensure stable air pressure in the liquid storage tank 400 and prevent leakage of the atomizing matrix in the liquid storage tank 400.

[0075] In some embodiments, the atomizing host 100 further includes a battery 150, and the bracket 121 includes a bracket body 1213 and an isolation plate 1214. One end of the bracket body 1213 is connected to the base 110 and encloses it to form an accommodating space, and the other end is provided with an air inlet 1211. The isolation plate 1214 is disposed in the accommodating space. One side of the isolation plate 1214 is enclosed with the bracket body 1213 and the sealing member 122 to form a collection chamber 123. The other side of the isolation plate 1214 and the bracket body 1213 form a battery compartment 131. The battery 150 is arranged in the battery compartment 131 and electrically connected to the circuit board 140.

[0076] In this embodiment of the application, the separation effect of the isolation plate 1214 allows the collection chamber 123 and the battery chamber 131 to be arranged side by side, which can achieve a reasonable layout, effectively utilize the accommodating space 130, and facilitate the miniaturization of the atomizing host 100.

[0077] In this embodiment, the battery 150 is arranged within the battery compartment 131, such that the battery 150 and the collection compartment 123 are arranged side by side. Figure 7 As shown, the battery 150 can be arranged above the circuit board 140, making the connection between the battery 150 and the circuit board 140 relatively simple.

[0078] In some embodiments, the isolation plate 1214 may be integrally formed with the bracket body 1213, or spliced ​​and fixed, etc., and this application does not specifically limit this.

[0079] In some embodiments, one end of the isolation plate 1214 is connected to the support body 1213, and the other end of the isolation plate 1214 extends toward the base 110; the sealing member 122 is sealed to the end of the isolation plate 1214 toward the base 110, and a first air guide hole 1223 communicating with the collection chamber 123 is provided on the sealing member 122 or the isolation plate 1214.

[0080] In this embodiment of the application, a first air guide hole 1223 is opened on the sealing member 122 or the isolation plate 1214. The first air guide hole 1223 can be connected to the atomizer 200 through the collection chamber 123. In this way, the external gas can enter the atomizer 200 after passing through the first air guide hole 1223 and the collection chamber 123 in sequence, so as to replenish the gas to the atomizer 200.

[0081] In some embodiments, after the atomizing device is sucked in, a negative pressure is generated in the atomizing airway 220. External gas can pass through the first air guide hole 1223 and the collection chamber 123 in sequence and then enter the atomizing airway 220 through the air inlet 1211 to replenish the atomizing airway 220 with gas and ensure the reliability of the atomizing device's next suction.

[0082] In some embodiments, after the atomizing matrix in the liquid storage chamber 400 flows into the atomizing air passage 220, a negative pressure is generated in the liquid storage chamber 400. External gas can sequentially pass through the first air guide hole 1223 and the collection chamber 123 and then enter the atomizing air passage 220 through the air inlet hole 1211, thereby replenishing the liquid storage chamber 400 with gas to balance the air pressure in the liquid storage chamber 400 and improve the reliability of the atomizing matrix flowing from the liquid storage chamber 400 into the atomizing air passage 220, that is, improve the reliability of oil supply to the heating element.

[0083] In some embodiments, the partition plate 1214 can be a flat plate structure, or it can be a U-shaped plate, etc. The partition plate 1214 and the support body 1213 can be closed to form a first sub-accepting groove 1241 with one end open. The sealing member 122 is sealed in the opening of the first sub-accepting groove 1241, so that the sealing member 122, the partition plate 1214, and the support body 1213 enclose a collection chamber 123. Figure 3 As shown, the first receiving tank 124 is divided into a first sub-receiving tank 1241 and a second sub-receiving tank 1242 by a partition plate 1214. The first sub-receiving tank 1241 is used to enclose and form a collection chamber 123, and the second sub-receiving tank 1242 is used to enclose and form a battery compartment 131.

[0084] In some embodiments, the materials of the isolation plate 1214 and the seal 122 may be the same or different. For example, the seal 122 may be a silicone component, and the isolation plate 1214 may be a plastic component, so that the seal 122 and the isolation plate 1214 can be sealed together. In other embodiments, the isolation plate 1214 may also be a silicone component. In this application, the materials of the isolation plate 1214 and the seal 122 are not specifically limited.

[0085] In some embodiments, such as Figure 2 As shown, the first air guide hole 1223 can be opened on the sealing member 122, so that the first air guide hole 1223 can be opened at the bottom of the collection chamber 123; or, the first air guide hole 1223 can also be opened on the partition plate 1214, so that the first air guide hole 1223 can be opened on the side of the collection chamber 123.

[0086] In some embodiments, the first air guide hole 1223 can be a circular hole, an elliptical hole, or a square hole, etc. The number of the first air guide holes 1223 can be one or at least two, etc. The specific size of the first air guide hole 1223 can be designed according to actual needs. In the embodiments of this application, the shape, number, and size of the first air guide hole 1223 are not specifically limited.

[0087] In some embodiments, the atomizing host 100 further includes a first liquid suction element 160 disposed within the collection chamber 123.

[0088] In this embodiment of the application, a first liquid-absorbing element 160 is provided in the collection chamber 123, so that the first liquid-absorbing element 160 can absorb and store the atomized matrix, which can reduce the risk of the atomized matrix flowing out of the collection chamber 123 from the first air guide hole 1223, thereby reducing the risk of the atomized matrix flowing to the circuit board 140.

[0089] In some embodiments, the first liquid-absorbing element 160 can be oil-wicking cotton, typically made of pure cotton nonwoven fabric, which has oil storage capacity. Utilizing the capillary structure and fiber affinity of cotton fibers, it can adsorb and store the atomized matrix. Alternatively, the first liquid-absorbing element 160 can also be polymer cotton, made from polymer materials through a needle-punching process, which has the characteristics of fast oil absorption, uniform oil absorption, and large oil storage capacity.

[0090] In some embodiments, the first air guide hole 1223 is formed in the seal 122, and the atomizing host 100 further includes a second liquid suction element 170, which is disposed between the circuit board 140 and the seal 122, and the second liquid suction element 170 is spaced apart from the circuit board 140; Figure 8 As shown, the second liquid-absorbing element 170 is provided with a second air guide hole 171, which is connected to the first air guide hole 1223.

[0091] In this embodiment, the second liquid-absorbing element 170 is disposed between the circuit board 140 and the seal 122, and the second liquid-absorbing element 170 is spaced apart from the circuit board 140. In this way, even if the atomized matrix in the collection chamber 123 leaks, it can be absorbed and stored by the second liquid-absorbing element 170, so as to further reduce the risk of the atomized matrix flowing to the circuit board 140 and reduce the risk of the circuit board 140 being corroded and damaged.

[0092] In some embodiments, the second liquid-absorbing element 170 may be oil-wicking cotton or polymer cotton, etc., but this application does not specifically limit this.

[0093] In this embodiment of the application, a second air guide hole 171 is opened on the second liquid absorption element 170, so that outside air can enter the first air guide hole 1223 through the second air guide hole 171, thereby supplying air to the atomizer 200.

[0094] In some embodiments, the second air guide hole 171 may be arranged opposite to the first air guide hole 1223 to allow air to enter the first air guide hole 1223 through the second air guide hole 171. In other embodiments, the second air guide hole 171 may also be staggered and spaced apart from the first air guide hole 1223. The shape, number, and size of the second air guide hole 171 can be arranged with reference to the first air guide hole 1223, and the shape, number, and size of the second air guide hole 171 may be the same as or different from the first air guide hole 1223. The second air guide hole 171 may be a circular hole, an elliptical hole, or a square hole, etc., and the number of the second air guide hole 171 may be one or at least two, etc. The specific size of the second air guide hole 171 can be designed according to actual needs. In the embodiments of this application, the shape, number, and size of the second air guide hole 171 are not specifically limited.

[0095] For example, a second air vent 171 may be connected to a first air vent 1223, or a second air vent 171 may be connected to multiple first air vents 1223, or multiple second air vents 171 may be connected to a first air vent 1223, etc.

[0096] In some embodiments, such as Figure 9 and Figure 10 As shown, the circuit board 140 is arranged on the base 110. The circuit board 140 is provided with a first through hole 141, and the base 110 is provided with a second through hole 111. The second through hole 111 is connected to the first air guide hole 1223 through the first through hole 141.

[0097] In this embodiment, outside air can pass through the second through hole 111, the first through hole 141, and the first air guide hole 1223 in sequence, and then enter the collection chamber 123, and then enter the atomizing air passage 220 of the atomizer 200 through the air inlet hole 1211, thereby supplying air to the atomizer 200.

[0098] In some embodiments, the second through hole 111, the first through hole 141, and the first air guide hole 1223 can be connected sequentially. The shape, number, and size of the second through hole 111 and the first through hole 141 can be arranged with reference to the first air guide hole 1223. The shape, number, and size of the second through hole 111 and the first through hole 141 can be the same as or different from the first air guide hole 1223.

[0099] For example, a second through hole 111 can be connected to a first through hole 141, or a second through hole 111 can be connected to multiple first through holes 141, or multiple second through holes 111 can be connected to a first through hole 141, etc.

[0100] In some embodiments, such as Figure 11 As shown, the atomizing host 100 also includes a sealing member 180, which is sequentially inserted through the second through hole 111, the first through hole 141 and the first air guide hole 1223; one end of the sealing member 180 is located outside the base 110 and the other end is located inside the collection chamber 123.

[0101] In this embodiment, the sealing member 180 is sequentially disposed through the second through hole 111, the first through hole 141, and the first air guide hole 1223, so that the sealing member 180 can block the air passage and prevent the atomizing matrix from leaking from the air passage before the atomizer 200 is used. Moreover, one end of the sealing member 180 is located outside the base 110, so that the sealing member 180 can be easily removed before the user uses it to avoid the air passage being blocked and affecting the user's inhalation.

[0102] In some embodiments, before the sealing element 180 is removed, the atomizing matrix in the atomizer 200 leaks into the collection chamber 123 through the air inlet 1211 and can be absorbed by the first liquid absorption element 160. If the first liquid absorption element 160 is full, since the collection chamber 123 is independent and sealed by the sealing element 180, the atomizing matrix can be stored in the collection chamber 123 and will not leak out.

[0103] In some embodiments, after the sealing element 180 is removed, if the first liquid-absorbing element 160 is full, the atomized matrix can be absorbed by the second liquid-absorbing element 170 after flowing out from the first air guide hole 1223. Moreover, the second liquid-absorbing element 170 is arranged at intervals with the circuit board 140, so that the atomized matrix will not flow to the circuit board 140.

[0104] In some embodiments, the second through hole 111, the first through hole 141, the second air guide hole 171, and the first air guide hole 1223 are all arranged in the airflow path. The second through hole 111, the first through hole 141, the second air guide hole 171, and the first air guide hole 1223 are all open, and the air passage is open. Outside air can enter the collection chamber 123 in sequence through the second through hole 111, the first through hole 141, the second air guide hole 171, and the first air guide hole 1223. At least one of the second through hole 111, the first through hole 141, the second air guide hole 171, and the first air guide hole 1223 is blocked. The air passage can be blocked, and outside air cannot enter the collection chamber 123, so that the liquid storage chamber 400 does not exchange air with the outside, which helps to maintain the air pressure balance in the liquid storage chamber 400 and reduce the risk of oil leakage.

[0105] In some embodiments, the sealing element 180 can be a plastic part or a plastic component. Before the user purchases the atomizer 200, the sealing element 180 can seal the second through hole 111, the first through hole 141, the second air guide hole 171, and the first air guide hole 1223 respectively, thereby blocking the air passage. After the user purchases the product and before using it, the sealing element 180 can be removed to allow the air passage to open.

[0106] In some embodiments, the sealing element 180 may be a one-piece molded structure or may be composed of multiple parts spliced ​​together. This application does not specifically limit this aspect.

[0107] In some embodiments, the sealing member 180 includes a first sealing portion 182 and a guide portion 181, the guide portion 181 being disposed at the end of the first sealing portion 182; along the axial direction of the sealing member 180, the projected area of ​​the guide portion 181 is smaller than the projected area of ​​the first sealing portion 182; the first sealing portion 182 is interference-fitted with the first air guide hole 1223; at least a portion of the guide portion 181 is inserted into the collection chamber 123.

[0108] In this embodiment, along the axial direction of the sealing member 180, the projected area of ​​the guide portion 181 is smaller than the projected area of ​​the first sealing portion 182, allowing the guide portion 181 to function as a guide and improving the ease of inserting the first sealing portion 182 into the first air guide hole 1223. The interference fit between the first sealing portion 182 and the first air guide hole 1223 improves the reliability of the sealing member 180 in sealing the first air guide hole 1223.

[0109] In some embodiments, the shape of the first sealing portion 182 can be adapted to the shape of the first air guide hole 1223 so that the first sealing portion 182 and the first air guide hole 1223 can be interference-fitted.

[0110] In some embodiments, the guide portion 181 may be tapered or frustum-shaped.

[0111] In some embodiments, the sealing member 180 includes a second sealing portion 183 and a limiting portion 184. The limiting portion 184 is disposed at the end of the second sealing portion 183. The second sealing portion 183 blocks the second through hole 111. The limiting portion 184 is located outside the base 110 and is limited and engaged with the base 110.

[0112] In this embodiment, the limiting part 184 is located outside the base 110 and is engaged with the base 110 to limit the movement, so that the limiting part 184 can play a limiting role, preventing the sealing part 180 from being fully inserted into the air passage and blocking the air passage, and making it easy to remove the sealing part 180 through the limiting part 184.

[0113] In some embodiments, along the axial direction of the sealing member 180, the projected area of ​​the limiting part 184 is larger than the projected area of ​​the second sealing part 183, and the projected area of ​​the limiting part 184 is larger than the projected area of ​​the second through hole 111, so as to facilitate the limiting part 184 and the base 110 to be limited and engaged.

[0114] In some embodiments, the shape of the second sealing member 180 may be adapted to the shape of the second through hole 111 so that the second sealing member 180 can block the second through hole 111.

[0115] In some embodiments, the base 110 may include a base shell 113 and a base shell seal 114. The base shell 113 is connected to and encloses the support body 1213 to form a receiving space 130. The base shell seal 114 is disposed within the receiving space 130 and connected to the base shell 113. The second through hole 111 includes a first sub-through hole 1111 and a second sub-through hole 1112. The first sub-through hole 1111 is formed in the base shell seal 114, and the second sub-through hole 1112 is formed in the base shell 113. The opening size of 111 is smaller than the opening size of the second sub-through hole 1112; the second sealing part 183 includes a first sub-sealing part 1831 adapted to the first sub-through hole 1111 and a second sub-sealing part 1832 adapted to the second sub-through hole 1112. The first sub-sealing part 1831 is connected between the second sub-sealing part 1832 and the limiting part 184. The first sub-sealing part 1831 seals the first sub-through hole 1111, and the second sub-sealing part 1832 seals the second sub-through hole 1112.

[0116] In this embodiment, the opening size of the first sub-through hole 1111 is smaller than that of the second sub-through hole 1112, so that the second through hole 111 can be a stepped hole. Since the first sub-through hole 1111 is located between the second sub-through hole 1112 and the first through hole 141, the stepped surface in the stepped hole can limit the second sub-blocking part 1832, which can prevent the blocking part 180 from being blocked in the air passage. Moreover, the second sub-blocking part 1832 can also block the first sub-through hole 1111, effectively preventing the liquid storage tank 400 from exchanging air with the outside, thereby ensuring the air pressure balance in the liquid storage tank 400.

[0117] In some embodiments, the shape of the first sub-through hole 1111 and the shape of the first sealing part 182 can be adapted to each other. The first sub-through hole 1111 can be a circular hole, a conical hole, a polygonal hole, etc., and the shape of the first sealing part 182 can be a cylinder, a cone, or a polygonal cylinder, etc.

[0118] In some embodiments, the shape of the second sub-through hole 1112 and the shape of the second sealing part 183 can be adapted to each other. The second sub-through hole 1112 can be a circular hole, a conical hole, a polygonal hole, etc., and the shape of the second sealing part 183 can be a cylinder, a cone, or a polygonal cylinder, etc.

[0119] In some embodiments, the atomizing host 100 further includes an electrode post 190, and a blind hole 1222 is provided on the side of the sealing member 122 opposite to the base 110. One end of the electrode post 190 is electrically connected to the circuit board 140, and the other end is inserted into the blind hole 1222. A clearance hole 1212 is also provided at the end of the bracket body 1213 away from the base 110. The clearance hole 1212 communicates with the battery compartment 131. The atomizer 200 includes a heating element 250. The pin of the heating element 250 passes through the clearance hole 1212 and is bent into the blind hole 1222 and electrically connected to the electrode post 190.

[0120] In this embodiment, one end of the electrode post 190 is electrically connected to the circuit board 140, and the other end is electrically connected to the pin of the heating element 250, so that the heating element 250 can be energized to atomize the atomizing matrix.

[0121] In some embodiments, the electrode post 190 may be inserted through the second liquid absorption element 170, with both ends of the electrode post 190 protruding from the second liquid absorption element 170, in order to improve the reliability of the electrode post 190 being electrically connected to the circuit board 140 and the pins, respectively.

[0122] In some embodiments, the second liquid guiding element may also be provided with a first through hole 172 and a second through hole 173. The first through hole 172 can be used to pass through the battery 150, and the second through hole 173 can be used to pass through the electrode post 190. The first through hole 172 can communicate with the second vent hole 171 through the second through hole 173, or the second through hole 173, the first through hole 172, and the second vent hole 171 can be provided independently.

[0123] In some embodiments, such as Figure 12 As shown, the sealing element 122 may also be provided with a groove 1221 and a blind hole 1222 that are connected to each other. The groove 1221, the blind hole 1222 and the second air guide hole 171 are arranged at intervals. The groove 1221 can be used to place at least part of the pins of the heating element 250. After the pins of the heating element 250 are bent, they are inserted into the blind hole 1222 and make interference contact with the electrode post 190 so that the electrode post 190 and the pins of the heating element are reliably electrically connected, and the current short circuit is avoided.

[0124] In some embodiments, the clearance hole 1212 is connected to the battery compartment 131, so that the pins of the heating element 250 pass through the battery compartment 131, and the pins of the heating element 250 can also be prevented from contacting the atomizing matrix, thereby improving the reliability of the electrical connection of the atomizing device.

[0125] In some embodiments, the heating element 250 may have a positive terminal and a negative terminal. The positive terminal can be connected to the circuit board 140 through one electrode post 190, and the negative terminal can be connected to the circuit board 140 through another electrode post 190.

[0126] The atomizing host described in this application embodiment has at least the following advantages:

[0127] In this embodiment, the sealing element and the bracket enclose a collection chamber, which is connected to the atomizing air passage of the atomizer through the air inlet. This allows leaked atomizing matrix or condensate from the atomizing air passage to be collected in the independent collection chamber through the air inlet. Since the circuit board is located outside the collection chamber, the collection chamber can also collect leaked atomizing matrix or condensate, thus preventing it from flowing onto the circuit board and effectively ensuring its reliability and stability, thereby guaranteeing the reliability of the atomizing device.
