[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] The first aspect of this application provides an atomizer, including: an atomizing chamber and an atomizing coil;

[0007] The atomizing chamber is configured to store an aerosol matrix. The atomizing chamber includes a first housing, a first mounting cover, and a first base. The first housing has two opposing open ends. The first mounting cover and the first base are respectively mounted on the two open ends. At least one of the first mounting cover and the first base is fixed to the first housing by laser welding.

[0008] The atomizing core is installed in the atomizing chamber and is used to atomize the aerosol matrix.

[0009] In some implementations, the first mounting cover includes a cover plate portion and a tubular portion, the cover plate portion being connected to the tubular portion, the cover plate portion having a first circumferential surface, the first circumferential surface being fixed to the inner wall of the first housing by laser welding, and the tubular portion being inserted into the atomizing core.

[0010] In some implementations, the cover plate has a first stepped surface, and the first housing abuts against the first stepped surface.

[0011] In some implementations, the atomizer further includes an air regulating ring, and the first housing has an air intake channel;

[0012] The regulating ring is repositioned to adjust the opening of the air inlet of the air intake channel by rotating itself.

[0013] The atomizing core has an atomizing air inlet, and the air outlet of the air inlet channel is connected to the atomizing air inlet.

[0014] In some implementations, the atomizer further includes a pressure ring, which is inserted and fixed to the first mounting cover so that the upper limit of the gas regulating ring in the height direction of the first housing is located on the atomizing chamber.

[0015] In some implementations, the first base includes an insertion part and a stop part, the insertion part being connected to the stop part; the insertion part is inserted into the first housing, the insertion part having a second circumferential surface, the second circumferential surface being fixed to the inner wall of the first housing by laser welding; the stop part abuts against the first housing.

[0016] In some implementations, the stop portion has a second stepped surface that abuts against the first housing.

[0017] In some implementations, the atomizer further includes a support cover and a first seal, the first housing having a third stepped surface;

[0018] In the height direction of the first housing, the first seal is clamped between the bracket cover and the third step surface;

[0020] In some implementations, a positioning groove is provided on the first base, and the first housing has a positioning protrusion, which is inserted into the positioning groove.

[0021] In some implementations, the atomizer further includes a liquid reservoir, wherein the first mounting cap cooperates with the first housing to form a receiving cavity, the liquid reservoir is disposed in the receiving cavity, and the liquid reservoir is used to adsorb the aerosol matrix.

This eliminates the need for additional snap-fit ​​structures and seals, significantly reducing the space occupied by the connection points and contributing to the compactness of the overall atomizer structure, meeting the design trends of miniaturization and lightweighting. It also reduces material usage, thereby lowering the weight and production cost of the atomizer. Furthermore, laser welding forms a permanent connection by melting materials at high temperatures. Compared to the mechanical interlocking of snap-fit ​​structures, the welded joint offers stronger sealing, ensuring a tight seal between the first mounting cap and the first housing, and between the first base and the first housing. This effectively prevents aerosol matrix leakage, maintaining stable sealing performance even during long-term use or in complex environments. Moreover, laser welding offers high precision, ensuring consistent sealing connections and avoiding sealing failures caused by tolerances or improper assembly in snap-fit ​​structures, thus improving the reliability and lifespan of the atomizer.

[0048] In related technologies, the assembly of the atomizer 100, such as the assembly of the liquid storage tank, mainly employs two methods: silicone sealing and ultrasonic sealing. However, both methods have their own characteristics and limitations in practical applications. Silicone seals cannot be fixed independently and require additional plastic snap-fit ​​components or other locking structures for secure fastening. However, these locking structures not only increase production steps but also result in a larger overall structural footprint, reducing the internal space utilization of the atomizer 100 and limiting the trend towards miniaturized product design. Furthermore, the locking structure can lead to unstable sealing performance due to tolerance issues. Ultrasonic sealing uses high-frequency vibration to generate heat through friction on the surface of the plastic parts, thus achieving a welded seal. However, in practical applications, the welded effect is often unstable, easily leading to incomplete sealing. To compensate for this deficiency, additional silicone rings are usually added for auxiliary sealing, further increasing structural complexity and space occupation. Similar to silicone sealing, the complex process of ultrasonic welding also increases production costs and results in low utilization of the internal space of the equipment.

[0049] Therefore, this application provides an atomizer 100 and an electronic atomization device to solve the problems in the related art.

[0050] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0051] Combination Figure 1 , Figure 3 and Figure 4 As shown, in one or more embodiments, the atomizer 100 provided in this application includes: an atomizing chamber 101 and an atomizing core 102; the atomizing chamber 101 is configured to store an aerosol matrix, and the atomizing chamber 101 includes a first housing 103, a first mounting cover 104 and a first base 105, the first housing 103 has two opposing open ends 106, the first mounting cover 104 and the first base 105 are respectively mounted on the two open ends 106, and at least one of the first mounting cover 104 and the first base 105 is fixed to the first housing 103 by laser welding; the atomizing core 102 is installed in the atomizing chamber 101, and the atomizing core 102 is used to atomize the aerosol matrix.

[0052] The atomizer 100 provided in this application embodiment uses laser welding to fix the first mounting cover 104 and the first base 105 to the first housing 103, replacing the snap-fit ​​structure and silicone seal in related technologies. This eliminates the need for additional snap-fit ​​structures and seals, significantly reducing the space occupied by the connection points and contributing to the compactness of the overall structure of the atomizer 100, meeting the design trends of miniaturization and lightweighting. It also reduces material usage, thereby lowering the weight and production cost of the atomizer 100. Furthermore, laser welding forms a permanent connection by melting materials at high temperatures. Compared to the mechanical interlocking of snap-fit ​​structures, the welded joint offers stronger sealing, ensuring a tight seal between the first mounting cover 104 and the first housing 103, and between the first base 105 and the first housing 103. This effectively prevents aerosol matrix leakage and maintains stable sealing performance even during long-term use or in complex environments. Furthermore, laser welding has high precision, which can ensure the consistency of the sealing connection and help avoid sealing failure caused by tolerance or improper assembly of the interlocking structure, thereby improving the reliability and service life of the atomizer 100.

[0053] For ease of description, in this embodiment, the height direction of the atomizing chamber 101 is set as the AA direction.

[0054] Combination Figure 1 and Figure 4As shown, in some embodiments, the first mounting cover 104 is located at one opening end 106, and the first base 105 is located at the other opening end 106. The atomizing chamber 101 has a receiving cavity 107 in which the aerosol matrix is ​​stored; the receiving cavity 107 can be formed by the first mounting cover 104 and the first housing 103. The first mounting cover 104 and the first base 105 are both fixed to the first housing 103 by laser welding. After the aerosol matrix is ​​atomized, an aerosol can be formed.

[0055] It should be noted that in some other possible implementations, in the atomizing chamber 101, only the first mounting cover 104 and the first housing 103 may be fixed by laser welding, or only the first base 105 and the first housing 103 may be fixed by laser welding.

[0056] See Figure 2 As shown, in some embodiments, the first housing 103 also has a liquid injection hole 108, which is connected to the receiving cavity 107. The atomizer 100 also includes a liquid injection plug 109, which can block the liquid injection hole 108. The liquid injection hole 108 can be used to inject an aerosol matrix into the receiving cavity 107.

[0057] See Figure 4 As shown, in some embodiments, the atomizer 100 further includes a liquid reservoir 110 disposed in the receiving cavity 107. The liquid reservoir 110 is used to adsorb the aerosol matrix, thereby continuously supplying the atomizing core 102 with the aerosol matrix, thus improving liquid storage and transmission efficiency, enabling the atomizer 100 to work stably for a long time without frequent liquid replenishment. For example, the liquid reservoir 110 can be made of polyester fiber, organic cotton, or silicone foam. Utilizing its good adsorption and permeability, it can slowly and evenly release the liquid (aerosol matrix) to the atomizing core 102, thereby reducing "dry burning" and improving atomization stability and safety.

[0058] In some embodiments, the first housing 103 is made of PC (Polycarbonate), PET (Polyethylene Terephthalate), PETG (Polyethylene Terephthalate Glycol-modified), PCTG (Poly-Cyclohexylenedimethylene Terephthalate Glycol-modified), or PCT (Polycyclohexylene Dimethylene Terephthalate); the first mounting cover 104 is made of PC (Polycarbonate), PET (Polyethylene Terephthalate), PETG (Polyethylene Terephthalate Glycol-modified), or PCTG (Poly-Cyclohexylenedimethylene Terephthalate Glycol-modified). The material of the first base 105 is PC (Polycarbonate), PET (Polyethylene Terephthalate), PETG (Polyethylene Terephthalate Glycol-modified), PCTG (Poly-Cyclohexylenedimethylene Terephthalate Glycol-modified), or PCT (Polycyclohexylene Dimethylene Terephthalate). It is understood that the materials of the first housing 103, the first mounting cover 104 and the first base 105 are not limited to the above five types. Other plastic materials can also be used as needed to achieve laser welding and fusion fixation between the first housing 103 and the first mounting cover 104, and between the first housing 103 and the first base 105.

[0059] Combination Figures 10 to 12As shown, in some embodiments, the first mounting cover 104 includes a cover plate portion 111 and a tubular portion 112. The cover plate portion 111 is connected to the tubular portion 112. The cover plate portion 111 has a first circumferential surface 113, which is fixed to the inner wall 114 of the first housing 103 by laser welding. The tubular portion 112 is inserted into the atomizing core 102. This facilitates sealing between the first mounting cover 104 and the first housing 103, reducing the number of parts used. For example, the tubular portion 112 can be used to form an atomization channel to facilitate user inhalation and realize the flow channel of the aerosol; the tubular portion 112 and the cover plate portion 111 can be integrally formed using a molding process, which can reduce the number of parts and ensure sealing. One end of the tubular part 112 is connected to the cover plate part 111, and the atomizing core 102 is inserted into the opposite end of the tubular part 112. One or more second sealing rings 115 can be fitted on the atomizing core 102. In this way, after the atomizing core 102 is inserted into the tubular part 112, the sealing between the atomizing core 102 and the tubular part 112 can be guaranteed. The second sealing ring 115 can be an O-ring.

[0060] See Figure 4 As shown, in some embodiments, the cover portion 111 has a first stepped surface 116, and the first housing 103 abuts against the first stepped surface 116. This limits the length of the tubular portion 112 of the first mounting cover 104 inserted into the first housing 103 and ensures the accuracy of the welding position between the cover portion 111 and the first housing 103. The first stepped surface 116 can be a plane, and it can be perpendicular to the height direction of the first housing 103, while the height direction of the first housing 103 can be parallel to the height direction of the atomizer 100. The surface of the first housing 103 that abuts against the first stepped surface 116 is a plane, which ensures the accuracy of the connection between the first mounting cover 104 and the first housing 103.

[0061] Combination Figure 4 , Figure 5 and Figure 13As shown, in some embodiments, the atomizer 100 further includes an air regulating ring 117, and the first housing 103 has an air intake channel 118; the air regulating ring 117 is repositioned to adjust the opening of the air inlet 119 of the air intake channel 118 by its own rotation; the atomizing core 102 has an atomizing air inlet 120, and the air outlet 121 of the air intake channel 118 is connected to the atomizing air inlet 120. This allows the air regulating ring 117 to adjust the airflow entering the atomizing core 102 to adjust the atomization effect. For example, the first housing 103 is tubular, the air inlet 119 of the air intake channel 118 is located circumferentially in the first housing 103, and in the height direction of the first housing 103, the air inlet 119 of the air intake channel 118 can be close to the cover plate portion 111. The length direction of the air intake channel 118 extends along the height direction of the first housing 103. An air regulating ring 117 is fitted onto the first housing 103, with its rotation axis parallel to the height direction of the first housing 103. The opening degree refers to the extent to which the air inlet 119 is open, specifically the effective ventilation area of ​​the air inlet 119, i.e., the area of ​​the air inlet 119 exposed after the air regulating ring 117 rotates relative to the first housing 103. When the opening degree increases, the airflow increases; when the opening degree decreases, the airflow decreases. By adjusting the opening degree, the amount of airflow entering the atomizer 100 can be precisely controlled, thereby adjusting the atomization effect. The air regulating ring 117 has an adjusting through-hole 122. When the air regulating ring 117 rotates relative to the first housing 103, the adjusting through-hole 122 and the air inlet 119 of the air intake channel 118 will be misaligned, thus adjusting the opening degree. The number of intake channels 118 can be 1, 2 or 3; the number of regulating holes 122 on the regulating ring 117 can be 1, 2 or 3; the number of regulating holes 122 can be equal to the number of intake channels 118.

[0062] Combination Figure 4 and Figure 13 As shown, in some embodiments, the atomizer 100 further includes a pressure ring 123, which is inserted and fixed to the first mounting cover 104 so that the upper limit of the regulating ring 117 in the height direction of the first housing 103 is located on the atomizing chamber 101. This pressure ring 123 ensures that the regulating ring 117 is confined to the first housing 103, and the regulating ring 117 can rotate. For example, the regulating ring 117 has a stepped through hole 124, and the pressure ring 123 can abut against the stepped surface of the stepped through hole 124, thereby confining the regulating ring 117 to the first housing 103 using the pressure ring 123. The pressure ring 123 can be inserted into the first mounting cover 104, and the fixed connection between the pressure ring 123 and the first mounting cover 104 can be an interference fit or fixed by adhesive bonding.

[0063] In some embodiments, the atomizer 100 further includes a mouthpiece 125, which is inserted into the first mounting cap 104. For example, the mouthpiece 125 is also inserted into a pressure ring 123, and a first sealing ring 126 may be provided between the pressure ring 123 and the mouthpiece 125 to achieve a sealed connection. The first sealing ring 126 may be an O-ring.

[0064] Combination Figure 4 and Figure 17 As shown, in some embodiments, the first base 105 includes an insertion portion 127 and a stop portion 128, with the insertion portion 127 connected to the stop portion 128. The insertion portion 127 is inserted into the first housing 103, and has a second circumferential surface 129, which is fixed to the inner wall 114 of the first housing 103 by laser welding. The stop portion 128 abuts against the first housing 103. This facilitates sealing between the first base 105 and the first housing 103, reducing the number of parts used. For example, the insertion portion 127 and the stop portion 128 can be integrally formed using a molding process, which reduces the number of parts and ensures sealing. Figure 6 and Figure 7 As shown, the first base 105 has an insertion hole 130, through which the atomizing core 102 is inserted into the tubular portion 112 of the first mounting cover 104.

[0065] Combination Figure 4 and Figure 17 As shown, in some embodiments, the stop portion 128 has a second stepped surface 131, which abuts against the first housing 103. This ensures the accuracy of the welding position between the first base 105 and the first housing 103. For example, the second stepped surface 131 can be a plane, and it can be perpendicular to the height direction of the first housing 103; the surface of the first housing 103 that abuts against the second stepped surface 131 is a plane, thus ensuring the accuracy of the connection between the first base 105 and the first housing 103.

[0066] Combination Figure 14 and Figure 17 As shown, in some embodiments, a positioning groove 132 is provided on the first base 105, and a positioning protrusion is provided on the first housing 103. The positioning protrusion is inserted into the positioning groove 132. This ensures that the first base 105 will not rotate relative to the first housing 103 about an axis parallel to the height direction of the first housing 103, and also serves as a foolproof mechanism. For example, the number of positioning grooves 132 is equal to the number of positioning protrusions 133, and the number of positioning grooves 132 can be one, two, or three. It is understood that the positioning protrusion can also be provided on the first base 105, while the positioning groove 132 is provided on the first housing 103.

[0067] Combination Figures 14 to 17 As shown, in some embodiments, the atomizer 100 further includes a support cover 134 and a first seal 135. The first housing 103 has a third stepped surface 136. In the height direction of the first housing 103, the first seal 135 is sandwiched between the support cover 134 and the third stepped surface 136. The first base 105 abuts against the support cover 134. The first seal 135 ensures that during use, the aerosol matrix in the receiving cavity 107 will not leak into the atomizing air inlet 120 or into the power supply device 200 of the electronic atomizing device. For example, the first base 105 has a support post 137 that abuts against the support cover 134, thus ensuring that the support cover 134 will not move in the height direction of the first housing 103. The number of support posts 137 can be two, three, or four. It is understood that the support cover can be made of rigid plastic, such as PET, PC, or PCTG; and the first seal 135 can be an O-ring.

[0068] Combination Figures 14 to 17 As shown, in some embodiments, the bracket cover 134 also has a plug-in post 143, and the first housing 103 has a socket 138. The plug-in post 143 is inserted into the socket 138. Thus, when the plug-in post 143 of the bracket cover 134 is inserted into the socket 138, the bracket cover 134 will not rotate about an axis parallel to the height direction of the first housing 103, ensuring the stability of the bracket cover 134 during use. For example, the number of plug-in posts 143 can be one, two, or three; the number of sockets 138 is equal to the number of plug-in posts.

[0069] Combination Figure 8 and Figure 9 As shown, in some embodiments, the atomizing core 102 includes a heating element 139, a liquid guiding element 140, and an atomizing support 141. The heating element 139 and the liquid guiding element 140 are mounted on the atomizing support 141. Through capillary action, the aerosol matrix in the liquid storage component 110 is transferred to the liquid guiding element 140, and then transported to the heating element 139 via the liquid guiding element 140, ensuring that the heating element 139 continuously receives a stable supply of aerosol matrix. The heating element 139 can be a heating mesh or a heating wire. When the heating wire is energized, it can atomize the liquid aerosol matrix, thereby forming an aerosol. The liquid guiding element 140 can be made of polyester fiber, organic cotton, or silicone foam. The atomizing core 102 also has a conductive electrode 142, which is electrically connected to the power supply device 200 to enable the power supply device 200 to supply power to the heating element 139 of the atomizing core 102.

[0070] During assembly, the atomizer 100 provided in this embodiment requires the bracket cover 134 and the first sealing member 135 to be installed in the first housing 103, and then the first base 105 to be inserted into the first housing 103. The liquid storage member 110 needs to be installed in the receiving cavity 107, and then the first mounting cover 104 to be inserted into the first housing 103. Then, a laser beam is directed perpendicularly to the height direction of the first housing 103, acting on the contact area between the first circumferential surface 113 and the inner wall 114 of the first housing 103, and the second circumferential surface 129 and the inner wall 114 of the first housing 103, causing localized material melting and fusion. This achieves welding and fixing between the first mounting cover 104 and the first housing 103, and welding connection between the first base 105 and the first housing 103.

[0071] See Figure 18 As shown, this application provides an electronic atomizing device, including: a power supply device 200 and an atomizer 100 as provided in any of the above embodiments, wherein the atomizer 100 is connected to the power supply device 200. The above device has the same technical effects as those provided in the foregoing embodiments, and will not be repeated here. For example, the power supply device 200 has a battery; the atomizer 100 and the power supply device 200 can be detachably connected, wherein the detachable connection can be achieved by inserting the atomizer 100 into the docking hole 201 on the power supply device 200.

[0072] It should be understood that, in the embodiments of this application, unless otherwise expressly specified and limited, the terms "connection," "fixed connection," "contact," etc., should be interpreted broadly. Those skilled in the art can understand the specific meanings of the various terms in the embodiments of this application according to the specific circumstances.
