Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0042] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] In related technologies, the various components in an atomizing device are typically sealed together using sealing rings. For example, a silicone sealing ring is used between the housing and the base of the support; or between the atomizing tube and the cavity of the support. This manufacturing method increases the number of parts in the product and also increases the difficulty of assembly.

[0044] like Figure 1 , Figure 2 and Figure 6 As shown, an embodiment of this application provides an atomizing device 100, relating to the field of electronic atomization technology, mainly used to atomize an aerosol matrix into an aerosol for user use. The atomizing device 100 includes a housing 110, a support member 130, and an atomizing assembly 120.

[0045] The housing 110 includes an atomizing tube 111, and a liquid storage space 113 is formed between the atomizing tube 111 and the housing 110.

[0046] In one embodiment, reference Figure 6 The liquid storage space 113 has a top integrally formed from the shell 110, and an open bottom, which allows for... Figure 7 The base 200 shown seals the open end, wherein the support 130 and the atomizing assembly 120 can be assembled on the base 200. Figure 5 The top of the support member 130 shown and Figure 6 The bottom end of the atomizing tube 111 shown is connected, thereby forming the liquid storage space 113 into a cavity that can accommodate the atomizing matrix.

[0047] In one embodiment, the junction between the base 200 and the housing 110, and the junction between the support 130 and the atomizing tube 111, are sealed using ultrasonic welding.

[0048] In one embodiment, the support 130 and the atomizing tube 111 are made of the same material at their contact points, such as PVC, PP, PE, ABS, etc. Ultrasonic welding is a process that joins two parts (usually plastic or metal) with similar melting points together using high-frequency vibration and pressure. It utilizes ultrasonic energy to generate frictional heat at the contact surface, causing the materials on the contact surfaces of the two parts to melt and solidify simultaneously, thereby achieving a connection. When ultrasonic welding is used to weld two parts of the same material, the sealing performance is better.

[0049] In one embodiment, reference Figure 5 The support member 130 includes a base 131 and a cavity 132 connected to the base 131. At least one side of the cavity 132 is provided with a liquid inlet 13211. An atomizing assembly 120 is positioned within the cavity 132. The atomizing assembly 120 is connected to a liquid storage space 113 via the liquid inlet 13211, allowing the atomizing matrix in the liquid storage space 113 to enter the atomizing assembly 120 within the cavity 132 through the liquid inlet 13211. The atomizing assembly 120 is used to heat the atomizing matrix, causing it to change from a liquid to a gaseous state, and mix with the airflow during user inhalation to form an aerosol.

[0050] In one embodiment, reference Figure 5 and Figure 6 The atomizing tube 111 consists of two parts: an inner tube 1111 and an outer tube 1112. The outer tube 1112 and the shell 110 are connected to form a liquid storage space 113. The bottom end of the outer tube 1112 is sealed to the top end of the support member 130, and the top end forms the aerosol outlet of the shell 110. The inner tube 1111 is located inside the outer tube 1112. The bottom end of the inner tube 1111 is inserted into the atomizing assembly 120 through the support member 130. The aerosol generated by the atomizing assembly 120 flows from the bottom end to the top end of the inner tube 1111. The top end of the inner tube 1111 is connected to the top end of the outer tube 1112.

[0051] It should be noted that in some embodiments, the inner tube 1111 may be omitted and only the outer tube 1112 may be provided; or, in some embodiments, the inner tube 1111 and the outer tube 1112 may be integrally formed.

[0052] refer to Figure 6The top of the housing 110 is provided with a rubber stopper 114, which is removably located at the top of the atomizing tube 111. When the atomizing device 100 needs to be started, the rubber stopper 114 is removed, allowing gas communication between the inside of the atomizing device 100 and the outside. The flowing air triggers the atomizing component 120 to start, heating the atomizing matrix and forming an aerosol that escapes from the top of the atomizing tube 111. When the atomizing device 100 needs to be turned off, the rubber stopper 114 is used to seal the top of the atomizing tube 111, preventing gas communication between the inside of the atomizing device 100 and the outside, thus preventing the atomizing component 120 from starting and turning off the atomizing device 100. At the same time, when the atomizing device 100 is not in use, the rubber stopper 114 seals the top of the atomizing tube 111, making it difficult for the atomizing matrix in the liquid storage space 113 to come into contact with the outside air and deteriorate.

[0053] In one embodiment, at least one side of the cavity 132 has an axially disposed second welding area 13222. Here, axial refers to the communication direction of the atomizing tube 111. The second welding area 13222 is disposed axially. Exemplarily, the second welding area 13222 is disposed along the width or thickness direction of the housing 110.

[0054] In one embodiment, the second welding area 13222 is the contact surface between the outer tube body 1112 and the cavity 132, that is, the circumferential surface where the two meet is the second welding area 13222. Ultrasonic welding is performed on the support member 130 and the atomizing tube 111 in the second welding area 13222, so that a sealed connection is formed between the atomizing tube 111 and the cavity 132 of the support member 130. There is no need to use a sealing ring to seal the connection between the atomizing tube 111 and the cavity 132, reducing the number of parts and reducing the assembly difficulty of the product.

[0055] In one embodiment, the atomizing component 120 is disposed inside the support member 130, and an inlet 13211 is provided because the atomizing component 120 and the liquid storage space 113 need to be connected by liquid.

[0056] In one embodiment, at least one side of the cavity 132 has an axially arranged ultrasonic reinforcement region 13221, and there are at least two liquid inlets 13211, which are distributed on both sides of the ultrasonic reinforcement region 13221.

[0057] In one embodiment, reference is made to Figure 4 In order to allow the atomizing matrix in the liquid storage space 113 to enter the atomizing component 120 more smoothly, liquid inlets 13211 are provided on both sides of the atomizing component 120.

[0058] Figure 1-7 In the flat atomizing device shown, the gap between the support member 130 and the inner wall of the housing 110 in the width direction is very small. Therefore, the arrangement of this embodiment is particularly suitable for use in flat atomizing devices. Figure 3As shown, since the cross-section of the housing 110 is elliptical, the liquid inlet 13211 is distributed on both sides of the cavity 132 along the width direction of the housing 110. There is a certain distance gap between the cavity 132 and the housing 110, which is conducive to the smoother inflow of the atomization matrix. When the liquid inlet 13211 is distributed on both sides of the cavity 132 along the thickness direction of the housing 110, the gap between the cavity 132 and the housing 110 is relatively narrow, reducing the flow rate of the atomization matrix and being not conducive to improving the atomization effect of the atomization device 100.

[0059] It should be noted that during the ultrasonic welding process, areas such as the openings and slots on the support member 130 that affect the structural strength will cause deformation of the support member 130 during the welding process, resulting in potential problems with the welding quality. That is, the existence of the liquid inlet 13211 will cause potential problems with poor welding.

[0060] In one embodiment, referring to Figure 5 , in order to eliminate the above-mentioned drawbacks, by increasing the number of liquid inlets 13211, increasing the liquid inlet area, maintaining the speed of the atomization matrix entering the atomization component 120, and the connecting wall between the two liquid inlets 13211 forms an ultrasonic reinforcement area 13221. By setting the ultrasonic reinforcement area 13221, the cavity 132 retains better support force at the liquid inlet 13211, eliminates the potential problem of easy deformation of the cavity 132 at the liquid inlet 13211, and improves the sealing performance at the connection between the cavity 132 and the atomization tube 111.

[0061] It should be noted that in one embodiment, as Figure 4 [[ID=X]]and Figure 5 shown, two liquid inlets 13211 are provided on one side of the cavity 132 in the width direction of the atomization device 100, and the number and arrangement of the liquid inlets 13211 can be set as required. For example, four liquid inlets 13211 are provided on each side, arranged in a "field" shape.

[0062] In some embodiments, the seat portion 131 has a first welding area 1313 arranged axially. The first welding area 1313 is located on the side of the seat portion 131 close to the housing 110, and the seat portion 131 and the housing 110 are hermetically connected by ultrasonic welding of the first welding area 1313.

[0063] Referring to Figure 6An opening is formed at the bottom of the housing 110, and the support member 130 is sealed and fitted into this opening. The support member 130 is housed within the housing 110, and the seat portion 131 is configured to be sealed and connected to the inner wall of the housing 110, while the cavity portion 132 is configured to be sealed and connected to the atomizing tube 111, thereby reducing or even preventing leakage of the atomizing matrix within the liquid storage space 113. The first welding area 1313 is the contact surface between the seat portion 131 and the housing 110. The seat portion 131 and the housing 110 are sealed and connected by ultrasonic welding through the first welding area 1313, eliminating the need for sealing rings at the connection between the seat portion 131 and the housing 110, reducing the number of parts and simplifying product assembly.

[0064] In one embodiment, the seat 131 of the support 130 and the housing 110 are made of the same material at the contact point, such as PVC, PP, PE, ABS, etc. The seat 131 and the housing 110 are sealed together by ultrasonic welding.

[0065] As mentioned above, the connection between the cavity 132 and the atomizing tube 111 is also ultrasonically welded. When the atomizing tube 111, the cavity 132, the seat 131, and the housing 110 are made of the same material, the ultrasonic welding process at the connection between the cavity 132 and the atomizing tube 111, and at the connection between the seat 131 and the housing 110, can be completed in one step, reducing the number of parts, reducing the assembly difficulty of the product, and improving the production efficiency of the atomizing device 100.

[0066] In some embodiments, reference Figure 6 The seat 131 is inserted into the housing 110 so that the side of the housing 110 near the liquid storage space 113 is in contact with the first welding area 1313, and at least part of the seat 131 abuts against the housing 110.

[0067] In some embodiments, the seat 131 is inserted into the housing 110, and the seat 131 is transitionally or interference-fitted with the side of the housing 110 near the liquid storage space 113, so that the side of the housing 110 near the liquid storage space 113 is in contact with the first welding area 1313, and at least part of the seat 131 abuts against the housing 110.

[0068] In one embodiment, when the material of the seat 131 is the same as that of the housing 110, the first welding area 1313 is axially arranged around the seat 131. (See reference...) Figure 3 and Figure 4 The outer periphery of the seat 131 has the same shape as the cross-section of the housing 110, both being elliptical. The first welding area 1313 has a cylindrical contact surface with the inner wall of the housing 110, which increases the contact area between the seat 131 and the housing 110. At the same time, it also improves the sealing of the connection between the seat 131 and the housing 110.

[0069] In some embodiments, the materials used for different parts of the seat 131 may be different. For example, some parts of the seat may be made of metal, while others may be made of materials such as PVC, PP, PE, or ABS. The parts made of the same material as the housing 110 and abutting against the housing 110 form a first welding area 1313. In this case, the first welding area 1313 is provided on both sides of the seat 131 along the width direction of the housing 110; or, the first welding area 1313 may also be provided on both sides of the seat 131 along the thickness direction of the housing 110.

[0070] In some embodiments, the cavity 132 is arranged in a ring around the central axis of the seat 131. For example... Figures 4 to 6 As shown, both the cavity 132 and the seat 131 are hollow columnar structures, and the cavity 132 and the seat 131 are connected. The axes of the cavity 132 and the seat 131 coincide, so that the cavity 132 is arranged in a ring around the central axis of the seat 131.

[0071] The atomizing tube 111 is at least partially abutted against the cavity 132, and the atomizing assembly 120 is inserted into the cavity 132 and the seat 131.

[0072] like Figure 6 As shown, the bottom end of the outer tube body 1112 of the atomizing tube 111 abuts against the cavity 132, and the outer tube body 1112 of the atomizing tube 111 and the cavity 132 are sealed together by ultrasonic welding. The atomizing assembly 120 is housed in the cavity 132, which shortens the distance that the atomizing matrix needs to travel from the liquid inlet 13211 directly into the atomizing assembly 120, thereby improving atomization efficiency.

[0073] In some embodiments, reference Figure 4 The support member 130 also includes a load-bearing part 1324 and a enclosure part 1323.

[0074] In one embodiment, the support portion 1324 is annular and arranged circumferentially around the central axis of the cavity 132. The support portion 1324 is disposed in the cavity 132, and the atomizing tube 111 at least partially abuts against the support portion 1324. Figure 6 As shown, the support part 1324 is in contact with the bottom surface of the outer tube body 1112 of the atomizing tube 111. When the outer tube body 1112 and the support part 1324 are made of the same material, the atomizing tube 111 and the support part 1324 are connected in a sealed manner by ultrasonic welding.

[0075] The enclosure portion 1323 is arranged in a ring around the central axis of the cavity portion 132, and the enclosure portion 1323 extends axially. For example... Figure 5 As shown, the enclosure part 1323 is disposed on the support part 1324, and the enclosure part 1323 is spaced apart from the cavity part 132, so that the cavity part 132, the support part 1324 and the enclosure part 1323 form a receiving space 1325, and the atomizing tube 111 is at least partially inserted in the receiving space 1325.

[0076] As mentioned above, the cavity 132 and the atomizing tube 111 are sealed together by ultrasonic welding. The cavity 132 has a second welding area 13222.

[0077] refer to Figure 5 and Figure 6 When the atomizing tube 111 is at least partially inserted into the receiving space 1325 and the surfaces of the atomizing tube 111 and the enclosure portion 1323 are in contact, the second welding area 13222 is located on the surface of the enclosure portion 1323.

[0078] When the atomizing tube 111 is at least partially inserted into the receiving space 1325, and the atomizing tube 111 and the surface of the cavity 132 near the enclosure 1323 are in contact, the second welding area 13222 is located at one end of the cavity 132 near the enclosure 1323.

[0079] In some embodiments, the seat 131 is provided with a slot 1311, and the atomizing device 100 further includes a seal 1312, which includes a sealing body 13122 and a plug portion 13121.

[0080] In one embodiment, after the support 130 and the housing 110 are assembled, a sealed liquid storage space 113 is formed. The atomizing matrix is ​​injected into the liquid storage space 113 through the slot 1311. After the atomizing matrix is ​​injected, the slot 1311 needs to be sealed.

[0081] Typically, using columnar connectors to seal the slots individually reduces assembly efficiency.

[0082] To address the aforementioned issues, the insertion part 13121 of this application not only has two columnar bodies for insertion into the slot 1311 for sealing, but also a plate-like structure connecting the two columnar bodies to form a single unit. This allows for simultaneous sealing assembly of both slots 1311 during assembly, improving assembly efficiency. Furthermore, the plate-like structure enhances the sealing performance of the connection between the insertion part 13121 and the seat part 131.

[0083] In some embodiments, the atomizing assembly 120 has a liquid-absorbing element that absorbs the atomizing matrix. Atomizing materials entering the atomizing device within the atomizing assembly 120 from the liquid inlet 13211 are collected in the liquid-absorbing element and gradually heated to become an aerosol. When the liquid-absorbing element lacks atomizing matrix, it automatically absorbs some atomizing matrix from the liquid inlet 13211 for atomization. Therefore, the amount of atomizing matrix stored in the liquid-absorbing element is relatively small, and leakage is essentially nonexistent. This can be achieved by setting a plate-like structure that allows for disassembly, such as... Figure 2 and Figure 6 As shown, the plate-shaped structure is located below the atomizing assembly 120, sealing the bottom of the liquid-absorbing component to prevent leakage.

[0084] In one embodiment, the connector 13121 is made of silicone. (See reference) Figure 2 and Figure 6 The cylindrical body of the insertion part 13121 has a hollow structure. The insertion part 13121 is relatively soft and easily deformed, which reduces the sealing performance of the slot 1311.

[0085] To address the aforementioned issues, a sealing body 13122 is disposed at the end of the insertion portion 13121 away from the seat portion 131. Before the insertion portion 13121 and the seat portion 131 are assembled, the sealing body 13122 is inserted into the insertion portion 13121, maintaining the strength of the insertion portion 13121 and preventing deformation. The sealing body 13122 is quickly and stably inserted into the slot 1311, improving the sealing performance of the slot 1311 and preventing the atomized matrix from leaking from the slot 1311.

[0086] like Figure 2 and Figure 6 As shown, the sealing body 13122 and the insertion part 13121 have two through holes, which serve as channels for air conduction and electrical conduction.

[0087] like Figure 6 As shown, the atomizing device 100 also includes a power supply component 140, which includes a bottom sealing plate 141 and two conductive posts 142 spaced apart on the bottom sealing plate 141. The bottom sealing plate 141 is located on the side of the sealing body 13122 away from the seat portion 131. Each conductive post 142 is located on the bottom sealing plate 141 and passes through one of the aforementioned through holes. The atomizing assembly 120 is electrically connected to the conductive post 142 via a wire. One of the two conductive posts 142 is a positive conductive post, and the other is a negative conductive post.

[0088] In one embodiment, there is a gap between the conductive post 142 and the through hole, forming a channel for gas conduction.

[0089] In some embodiments, such as Figure 6 As shown, the bottom sealing plate 141 is also provided with an adsorption element 150, which is correspondingly located on the side of the atomizing assembly 120 away from the cavity 132. The adsorption element 150 is used to absorb the atomizing matrix and prevent leakage. The adsorption element 150 and the bottom sealing plate 141 are sealed and separated to prevent the atomizing matrix from damaging the bottom sealing plate 141.

[0090] In some embodiments, the cavity 132 includes a first end 1321 and a second end 1322.

[0091] like Figure 4 and Figure 5 As shown, the first end 1321 and the second end 1322 are spaced apart along the axial direction. The first end 1321 is connected to the seat 131, and the liquid inlet 13211 is provided on the first end 1321. The second welding area 13222 is provided on the second end 1322.

[0092] In some embodiments, the housing 110 includes a liquid storage section 112, which is connected to the atomizing tube 111 to form a liquid storage space 113.

[0093] like Figure 3 and Figure 6 As shown, the liquid storage section 112 is arranged in a ring around the central axis of the support member 130. In one embodiment, the cross-section of the liquid storage section 112 is elliptical, which is convenient for the user to grip.

[0094] The side of the liquid reservoir 112 closest to the liquid reservoir space 113 is in contact with the first welding area 1313 of the seat 131. When the liquid reservoir 112 and the seat 131 are made of materials with similar melting points, such as PVC, PP, PE, or ABS, the liquid reservoir 112 and the seat 131 are connected in a sealed manner by ultrasonic welding.

[0095] The support member 130 at least partially abuts against the liquid storage part 112, so that the liquid storage part 112 and the support member 130 have mutually fitting surfaces, and ultrasonic welding is performed.

[0096] The atomizing tube 111 is inserted into the liquid storage section 112 and abuts against the support member 130. The atomizing tube 111 is arranged in a ring around the central axis of the support member 130, and the end of the atomizing tube 111 near the support member 130 is welded to the support member 130. When the support member 130 and the atomizing tube 111 are made of materials with similar melting points, such as PVC, PP, PE, and ABS, the support member 130 and the atomizing tube 111 are connected in a sealed manner by ultrasonic welding.

[0097] refer to Figure 6 The atomizing tube 111 has a flow guiding channel, the atomizing assembly 120 has an atomizing channel, and the support 130 has an air intake channel, with the atomizing channel connecting the air intake channel and the flow guiding channel. External gas flows through the air intake channel of the support 130 to the atomizing channel of the atomizing assembly 120, and the aerosol generated by the atomizing assembly 120 flows to the outside through the flow guiding channel of the atomizing tube 111.

[0098] In some embodiments, the housing 110 further includes a limiting portion 1121.

[0099] The limiting part 1121 is disposed inside the liquid storage part 112, and the support member 130 at least partially abuts against the limiting part 1121.

[0100] like Figure 3 and Figure 6 As shown, the edge of the seat 131 abuts against the limiting part 1121. The limiting part 1121 is formed by protruding from the side of the liquid storage part 112 near the atomizing tube 111, or a stepped structure is formed at the limiting part 1121.

[0101] As mentioned above, the seat 131 and the side of the housing 110 near the liquid storage space 113 are transitionally or interference-fitted. Before the ultrasonic welding process between the seat 131 and the housing 110 is completed, the seat 131 is movable relative to the housing 110, thereby adjusting the relative position of the seat 131 and the housing 110 so that the seat 131 and the limiting part 1121 are in abutting state.

[0102] like Figure 1 , Figure 6 and Figure 7 As shown, this application also provides an electronic atomizing device 1000, including a base 200 and an atomizing device 100 in any of the above embodiments, wherein the base 200 and the atomizing device 100 are fitted together to define a receiving cavity 210.

[0103] Furthermore, the base 200 is equipped with an air intake hole, such as Figure 7 As shown, the air inlet is formed in the middle of the base 200, and the air inlet is connected to the atomization channel of the atomization assembly 120 through the receiving cavity 210 to form an air passage.

[0104] refer to Figure 6 and Figure 7 The gas flow direction within the atomizing device 100 is as follows: external gas passes through... Figure 7 In the middle of the base 200, the air inlet at the middle position enters the receiving cavity 210. The gas in the receiving cavity 210 enters the air inlet channel of the support member 130 through the gap between the conductive post 142 and the through hole on the plug part 13121. The outside air flows to the atomization channel of the atomizing component 120, triggering the atomizing component 120 to start. The generated aerosol flows to the outside through the guide channel of the atomizing tube 111.
