[0039] Please continue reading Figure 1 and Figure 2 The atomizer assembly 100 includes a main shell 10, an upper cover 20, a sealing member 30, a heating element 40, a base 50, and an electrode 60. The base 50 is connected to one end of the main shell 10, the electrode 60 is installed on the base 50 and is electrically connected to the power supply assembly, the upper cover 20 is accommodated in the main shell 10, the heating element 40 is accommodated in the upper cover 20 through the sealing member 30, the atomized liquid is stored in the main shell 10 and can flow to the heating element 40 through the upper cover 20, the heating element 40 can heat the atomized liquid to generate an aerosol, and the generated aerosol flows out of the main shell 10 for human inhalation.

[0040] Specifically, the main housing 10 is a hollow housing structure, and the height direction of the main housing 10 is a first direction ( Figure 1 The length direction of the main housing 10 is the second direction ( Figure 1 The width direction of the main shell 10 is the third direction, and the first direction, the second direction and the third direction are perpendicular to each other.

[0041] The main housing 10 has an upper cover accommodating chamber, a main housing airflow channel 12, and a liquid storage chamber 14.

In this way, the atomized liquid can be stored in the two liquid storage chambers 14, and the aerosol generated by the heating element 40 can flow out of the main housing 10 along the first direction through the main housing airflow channel 12.

[0042] The upper cover 20 is inserted into the upper cover accommodating cavity along the first direction and is sealed and connected to the inner wall of the upper cover 20 through a sealing ring. The upper cover 20 is provided with a heating element accommodating cavity and a drainage channel, and the upper cover 20 and the main shell 10 jointly define an upper cover airflow channel connected to the main shell airflow channel 12. The heating element accommodating cavity is used to accommodate the heating element 40, and the drainage channel connects the upper cover airflow channel and the heating element accommodating cavity.

[0043] In this way, the airflow generated by the heating element 40 can flow into the main shell airflow channel 12 through the upper cover airflow channel, and the condensate formed when the aerosol is cooled in the upper cover airflow channel can return to the heating element containing cavity through the drainage channel, thereby avoiding pollution caused by leakage of the condensate, and the condensate returned to the heating element containing cavity can be atomized again by the heating element 40, effectively reducing the waste of atomized liquid.

[0044] like Figure 1 , Figure 3 as well as Figure 4 As shown, the upper cover 20 includes a receiving portion 21 and a guide portion 23 connected to each other, and the receiving portion 21 is located on the side of the guide portion 23 away from the main shell airflow channel 12 and the liquid storage chamber 14. The heating element receiving chamber is opened in the receiving portion 21, and there is a gap between the outer wall of the receiving portion 21 and the inner wall of the main shell 10 to define the receiving portion air inlet channel, and the drainage channel is provided at one end of the receiving portion 21 connected to the guide portion 23. There is a gap between the outer wall of the guide portion 23 and the inner wall of the main shell 10 to define the guide portion air inlet channel, and the guide portion 23 is provided with a guide portion air outlet channel connecting the guide portion air inlet channel and the main shell airflow channel 12.

[0045] In this way, the air inlet channel of the accommodating part, the air inlet channel of the guiding part and the air outlet channel of the guiding part are connected in sequence to form an upper cover airflow channel together, and the aerosol generated from the heating element 40 can flow into the main shell airflow channel 12 through the air inlet channel of the accommodating part, the air inlet channel of the guiding part and the air outlet channel of the guiding part in sequence along with the airflow, and the condensed liquid formed when the aerosol is cooled in the air inlet channel of the guiding part and the air outlet channel of the guiding part can return to the heating element accommodating cavity through the drainage channel.

[0046] Specifically, the guide portion 23 includes a guide portion top wall, a guide portion bottom wall, and a guide portion side wall. The guide portion top wall and the guide portion bottom wall are arranged opposite to each other in the first direction, the guide portion side wall is connected between the guide portion top wall and the guide portion bottom wall, and the guide portion bottom wall is connected to the accommodating portion 21. The cross-sectional area of ​​one end of the guide portion side wall close to the accommodating portion 21 in a direction perpendicular to the first direction is smaller than the cross-sectional area of ​​one end of the guide portion 23 away from the accommodating portion 21 and one end of the accommodating portion 21 connected to the guide portion 23 in a direction perpendicular to the first direction, and a gap is formed between the guide portion side wall and the inner wall of the main housing 10 to define a guide portion air inlet passage extending in a circumferential direction around the guide portion 23.

[0047] Furthermore, the top wall of the guide portion is provided with two liquid inlet holes 232 and one guide portion air outlet hole 234. The two liquid inlet holes 232 are spaced apart in the second direction, and each liquid inlet hole 232 is connected to the liquid storage chamber 14 and the heating element accommodating chamber, respectively. A guide portion air outlet groove 236 is provided on the side of the guide portion side wall facing the accommodating portion 21, and the guide portion air outlet groove 236 penetrates the guide portion 23 along the third direction and is connected to the guide portion air outlet hole 234 to form a guide portion air outlet channel together.

[0048] In this way, the atomized liquid stored in the liquid storage chamber 14 can flow into the heating element accommodating chamber through the liquid inlet hole 232 to contact the heating element 40, and the aerosol flows into the guide part air outlet groove 236 through the guide part air inlet channel, and then flows into the main shell air flow channel 12 through the guide part air outlet hole 234.

[0049] The accommodating portion 21 includes a accommodating portion top wall, a accommodating portion bottom wall and a accommodating portion side wall. The accommodating portion top wall and the accommodating portion bottom wall are arranged opposite to each other in the first direction, and the accommodating portion side wall is connected between the accommodating portion top wall and the accommodating portion bottom wall, and the accommodating portion top wall, the accommodating portion bottom wall and the accommodating portion side wall jointly enclose a heating element accommodating cavity with a bottom opening. The accommodating portion top wall is connected to the guiding portion bottom wall, and there is a gap between the accommodating portion side wall and the inner wall of the main shell 10 on both sides in the second direction to form two accommodating portion air inlet channels extending along the first direction. The air inlet channel drainage channel is formed on the accommodating portion side wall and is connected to the accommodating portion top wall. In this way, the condensate in the guiding portion air inlet channel and the guiding portion air outlet channel can flow into the heating element accommodating cavity through the drainage channel.

[0050] Specifically, in one embodiment, a drainage groove 212 connected to the top wall of the accommodating portion is provided at one end of the side wall of the accommodating portion close to the guide portion, and a drainage hole 2121 connected to the heating element accommodating cavity is provided on the groove wall of the drainage groove 212 facing the accommodating cavity to form a drainage channel. In this way, the condensate in the guide portion air inlet channel and the guide portion air outlet channel of the guide portion 23 can enter the drainage groove 212, and then enter the heating element accommodating cavity through the drainage hole 2121.

[0051] Further, the side wall of the accommodating portion is provided with a plurality of drainage grooves 212 on both sides in the third direction, and the plurality of drainage grooves 212 are spaced apart in the second direction, and a support column 214 extending along the first direction is provided between two adjacent drainage grooves 212, and a drainage hole 2121 is provided in each drainage groove 212. In this way, the support column 214 can support the accommodating portion 21 to prevent the accommodating portion 21 from deforming during assembly. Specifically, in some embodiments, the side wall of the accommodating portion is provided with two drainage grooves 212 on both sides in the third direction, and in other embodiments, the side wall of the accommodating portion is provided with three drainage grooves 212 on both sides in the third direction. It can be connected, and the number of drainage grooves 212 is not limited, and can be set as needed to meet different requirements.

[0052] In some embodiments, both sides of the top wall of the accommodating portion in the third direction are provided with guide surfaces connected to the drainage groove 212, and the distance between the guide surface and the bottom wall of the guide portion gradually increases in the direction from the end of the guide surface away from the drainage groove 212 to the drainage groove 212. In this way, the condensate in the guide portion air inlet channel and the guide portion air outlet channel of the guide portion 23 flows smoothly into the drainage groove 212 under the guiding effect of the guide surface.

[0053] Specifically, in one embodiment, a first guide surface 216 and two second guide surfaces 218 are provided on both sides of the top wall of the accommodating portion in the third direction. The first guide surface 216 is located on the side of the drainage groove 212 close to the guide portion 23 in the third direction, and the first guide surface 216 extends from one end of the top wall of the accommodating portion to the other end of the top wall of the accommodating portion along the second direction, and the first guide surface 216 extends obliquely toward the drainage groove 212 from the side close to the guide portion 23. The two second guide surfaces 218 are respectively located on the opposite sides of the drainage groove 212 in the second direction, and each second guide surface 218 extends from one end of the accommodating portion 21 to the drainage groove 212 along the first direction. It can be understood that the shape and number of the guide surfaces are not limited, and can be set according to the shape of the accommodating portion 21 to play a good drainage role.

[0054] like Figure 1 , Figure 5 as well as Figure 6 As shown, in some cases, the atomizer assembly 100 also includes a seal 30, which includes a seal top wall and a seal side wall extending from the seal top wall along the first direction toward the same side of the seal top wall. The seal 30 is sleeved on the outside of the heating element 40 and accommodated in the heating element accommodating cavity to oil-proof and fix the heating element 40. The seal side wall is provided with connecting holes 32 connecting the drainage channel and the outer wall of the heating element 40 on both sides in the third direction.

[0055] Furthermore, a receiving groove 34 is formed on the inner side wall of the sealing member 30 facing the heating element 40. The receiving groove 34 is located on the side of the connecting hole 32 away from the guide portion 23 and is connected to the connecting hole 32. In this way, the condensed liquid flowing into the sealing member 30 from the connecting hole 32 can be temporarily stored in the receiving groove 34, while increasing the contact area between the liquid and the heating element 40.

[0056] The base 50 is matched to the side of the main housing 10 where the main accommodating cavity is provided. The base 50 includes a base bottom wall and a base side wall extending from the edge of the base bottom wall along the first direction toward the same side of the base bottom wall. The base side wall is provided with card slots on opposite sides in the second direction, and the accommodating portion 21 of the upper cover 20 is provided with buckles that are engaged with the card slots along the first direction on both sides in the second direction. The base bottom wall is provided with an electrode mounting hole, and the electrode 60 can pass through the base bottom wall through the electrode mounting hole to be electrically connected to the heating element 40.

[0057] In this way, the base 50 is snap-connected with the upper cover 20 and installed at one end of the main shell 10, and a base receiving cavity with a bottom wall is formed between the base 50 and the bottom surface of the heating element 40 accommodated in the accommodating portion 21, and the condensate generated by the aerosol condensation can be stored in the base receiving cavity.

[0058] Furthermore, an exhaust port 54 connected to the base receiving cavity is respectively provided on both sides of the base side wall in the second direction, and the maximum distance of the exhaust port 54 relative to the liquid storage cavity 14 is smaller than the distance between the bottom wall of the base receiving cavity and the liquid storage cavity 14, thereby preventing condensed liquid in the base receiving cavity from flowing out through the exhaust port 54.

[0059] In some embodiments, the heating element 40 is formed of a microporous material, which can heat the atomized liquid contacting its surface to atomize the atomized liquid. It is understood that the material forming the heating element 40 is not limited thereto and can be set as needed to meet different requirements.

[0060] like Figure 2 As shown, the airflow path in the above-mentioned atomization assembly 100 is as follows:

[0061] The aerosol generated by the heating element 40 heating the atomized liquid first enters the base receiving cavity at the bottom of the heating element 40, then flows toward the two exhaust ports 54 along the second direction and flows out from the exhaust ports 54, then moves toward the upper cover 20 along the first direction, and then passes through the accommodating part air inlet channel, the guiding part air inlet channel, the guiding part air outlet groove 236, and the guiding part air outlet hole 234 in sequence and flows into the main shell air flow channel 12.

[0062] like Figure 4 As shown, the flow path of the condensate in the above-mentioned atomization assembly 100 is as follows:

[0063] The condensate formed by the aerosol in the air flow channel of the upper cover flows into the drainage groove 212 along the guide surface, and then flows into the heating element accommodating cavity through the drainage hole 2121 and contacts the heating element 40, so as to be re-atomized by the heating element 40 to generate aerosol.

[0064] The above-mentioned atomization assembly 100 and the atomization device equipped with it realize secondary recovery of condensate by setting up the drainage channel, which significantly reduces the waste of atomized liquid while avoiding pollution caused by leakage of condensate. At the same time, the base receiving cavity can further accommodate condensate to ensure that other electronic components will not be damaged by condensate.

[0065] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0066] The above-mentioned embodiments only express several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
