[0032] In this embodiment, by providing at least two laser welding areas 300 at the junction of the seat 200 and the cup 100, and by providing a corresponding light-transmitting part on the cup 100, the seat 200 can be welded and sealed using laser welding technology after being assembled to the cup 100, forming a multi-seal structure. This helps to improve the reliability of the seal and reduce the risk of seal failure.

[0033] An embodiment of the atomizer in this application:

[0034] In one embodiment, please refer to Figure 1 and Figure 2 The atomizer includes a cup body 100 and a base 200; the cup body 100 has a cup cavity 110 for storing atomizing liquid, and a mounting port 120 communicating with the cup cavity 110 is provided on one side of the cup body 100; the base 200 is assembled at the mounting port 120 and is used to close the mounting port 120.

[0035] A laser welding area 300 is provided between the outer peripheral surface of the base 200 and the cavity wall of the cup cavity 110. The laser welding area 300 surrounds the base 200 and is provided at least two times at intervals along the assembly direction of the base 200 to prevent the atomized liquid from leaking between the base 200 and the cavity wall of the cup cavity 110. At least one light-transmitting part is provided on the cup body 100 corresponding to the laser welding area 300, and the light-transmitting part is used to allow the laser forming the laser welding area 300 to pass through.

[0036] During atomizer production, after the base 200 is assembled to the mounting port 120 of the cup 100, a laser is emitted from the outside of the cup 100 towards the light-transmitting part. The laser passes through the light-transmitting part and acts on the outer peripheral surface of the base 200 and the cavity wall of the cup cavity 110 to perform welding, creating a laser welding area 300 that connects the base 200 and the cup 100. This achieves a seal between the base 200 and the cup 100, preventing the atomized liquid from leaking from between the base 200 and the cavity wall of the cup cavity 110.

[0037] Laser welding sealing offers improved sealing reliability compared to assembly-type seals such as silicone rings. Furthermore, by creating at least two laser-welded areas (300mm), a multi-layered sealing structure can be formed, further enhancing sealing reliability and reducing the risk of seal failure.

[0038] In one embodiment, please refer to Figure 1 and Figure 2The cup body 100 is made of a light-transmitting material that allows lasers to pass through, so that the entire cup body 100 can be used as a light-transmitting part, which facilitates manufacturing and use. In some embodiments, a material with a light transmittance of not less than 15% can be selected as the light-transmitting material to facilitate laser welding.

[0039] In one embodiment, the width of a single laser-welded area 300 is not less than 1.2 mm, such as 1.2 mm, 1.5 mm, 1.8 mm, 2.0 mm, etc., to ensure a sealing effect and help reduce the risk of seal failure due to excessively narrow sealing width. In other embodiments, depending on the sealing requirements, the width of the laser-welded area 300 may also be less than 1.2 mm, such as 1.1 mm, 1.0 mm, etc.

[0040] Those skilled in the art will understand that, in order to form a laser welding region 300 between the outer peripheral surface of the base 200 and the cavity wall of the cup cavity 110, in different embodiments, the outer peripheral surface of the base 200 or the cavity wall of the cup cavity 110 should be a welding material that can be melted by laser irradiation, or a welding material that can be melted by laser irradiation should be sandwiched between the outer peripheral surface of the base 200 and the cavity wall of the cup cavity 110. Furthermore, the material of the laser welding region 300 (i.e., the aforementioned welding material) should have a color that can absorb laser light, such as black, red, blue, or other colors.

[0041] In one embodiment, please refer to Figure 3 A welding sealing line 210 is provided on the outer peripheral surface of the base 200. The welding sealing line 210 is used to be melted by laser to form a laser welding area 300. The welding sealing line 210 can be integrally formed with the base 200, that is, a part of the base 200 serves as the welding sealing line 210; the welding sealing line 210 can also be formed by welding material fixed to the outer peripheral surface of the base 200 by means of bonding, snapping, etc. In other embodiments, the welding sealing line 210 can also be fixed to the cavity wall of the cup cavity 110, or clamped between the base 200 and the cavity wall of the cup cavity 110 during the assembly of the base 200.

[0042] In one embodiment, the seat 200 is interference-fitted with the cavity wall of the cup cavity 110, that is, the seat 200 is interference-fitted into the cup cavity 110, which helps to improve the sealing effect of the cup cavity 110.

[0043] In a further embodiment, the outer diameter of the portion of the seat 200 at least having a welded sealing line 210 can be set to be larger than the inner diameter of the cup cavity 110, so that during assembly, the portion of the seat 200 at least having a welded sealing line 210 is in an interference fit with the cavity wall of the cup cavity 110, which helps to improve the sealing effect. In one embodiment, the interference amount at the interference fit can be set to 0.03mm to 0.05mm, so as to improve the sealing effect while facilitating assembly.

[0044] In different embodiments, the position of the interference fit between the seat 200 and the cavity wall of the cup cavity 110 is not limited, and the range of the interference amount is also not limited, as long as it can meet the assembly and sealing requirements.

[0045] In one embodiment, please refer to Figure 4 The atomizer also includes an atomizing tube 400, which is disposed in the cup cavity 110. The atomizing tube 400 is provided with a liquid guiding hole 410 for the atomized liquid in the cup cavity 110 to enter. Atomizing core 420 is provided in the atomizing tube 400 corresponding to the liquid guiding hole 410. The atomizing core 420 is used to heat the atomized liquid to generate an aerosol.

[0046] A gas outlet channel 130 is provided on the cup body 100 corresponding to the atomizing tube 400. One end of the atomizing tube 400 is mounted on the base 200 and communicates with the external gas of the atomizer; the other end communicates with the gas outlet channel 130 to allow aerosol discharge. For example, the gas outlet channel 130 can be formed by a tube structure located on the side of the cup body 100 opposite to the mounting port 120. One end of the tube structure can be located in the cup cavity 110, and the other end can protrude from the cup body 100 for use as a mouthpiece. Furthermore, the portion of the tube structure protruding from the cup body 100 can be covered with a flexible material such as silicone to improve the mouth-holding experience.

[0047] In one embodiment, please refer to Figure 3 and Figure 4 The base 200 includes a first part 220, a second part 230, and a connecting part 240. The first part 220 has an air intake channel 221 for communicating with the outside of the atomizer. The connecting part 240 connects the first part 220 and the second part 230 so that the first part 220 and the second part 230 alternately form an air intake duct 250 communicating with the air intake channel 221. The air intake duct 250 communicates with the atomizing tube 400. Laser welding areas 300 are formed on the periphery of both the first part 220 and the periphery of the second part 230. The laser welding area 300 on the periphery of the second part 230 forms a primary seal to prevent the atomized liquid from entering the space between the base 200 and the cavity wall of the cup cavity 110 from the cup cavity 110. The laser welding area 300 on the periphery of the second part 230 forms a secondary seal to prevent the atomized liquid from leaking out of the atomizer.

[0048] For example, both the first part 220 and the second part 230 are generally cylindrical in shape. The second part 230 is closer to the atomizing tube 400 than the first part 220. One end of the atomizing tube 400 passes through the second part 230 and is inserted and fixed to the first part 220. Air intake channels 221 are provided on both sides of the first part 220. The connecting part 240 consists of two columnar bodies spaced around the atomizing tube 400. One end of each columnar body is integrally connected to the first part 220, and the other end is integrally connected to the second part 230, so that the first part 220 and the second part 230 form an air intake passage 250 communicating with the air intake channel 221. An air intake hole is provided on the tube wall of the atomizing tube 400 located between the first part 220 and the second part 230, allowing air from outside the atomizing tube 400 to sequentially pass through the air intake channel 221, the air intake passage 250, and the air intake hole into the inner cavity of the atomizing tube 400.

[0049] In one embodiment, the first portion 220 may have a protruding tube portion 222 on the side near the second portion 230, and the inner cavity of the protruding tube portion 222 serves as a partial air intake channel 221. This makes it difficult for the atomizing liquid to enter the air intake channel 221 even if it leaks into the air intake channel 250 from the atomizing tube 400, and it is not easy for it to leak from the air intake channel 221.

[0050] In one embodiment, to facilitate the insertion of the base into the cup body 100 through the mounting port 120, the first portion 220, the second portion 230, and the connecting portion 240 are configured such that the outer peripheral surfaces of the first portion 220 and the second portion 230 are located outside the outer peripheral surface of the connecting portion 240, so that a step portion 260 is formed on the outer side of the connection between the connecting portion 240 and the first portion 220 and the second portion 230, so that when the base is inserted into the cup body 100, the connecting portion 240 remains separated from the cavity wall of the cup cavity 110, thereby reducing frictional resistance during assembly.

[0051] For example, the two columnar bodies that make up the connecting portion 240 have an outer surface on the side that is away from each other. This outer surface is spaced apart from the outer peripheral surfaces of the first portion 220 and the second portion 230 and is located inside the outer peripheral surfaces of the first portion 220 and the second portion 230, so that the two columnar bodies and the first portion 220 and the second portion 230 form a stepped portion 260.

[0052] In one embodiment, the first portion 220 has a flange 223 on the side opposite to the second portion 230. The flange 223 engages with the mounting opening 120 to axially position the base 200. The specific shape of the flange 223 is not limited; for example, it can be annular, as long as it allows the base to engage with the mounting opening 120. Precise assembly of the base and the cup 100 helps improve the accuracy of laser welding and enhances sealing reliability.

[0053] In one embodiment, the outer peripheral surface of the first portion 220 has a positioning protrusion 224, which is located on the side of the protruding edge 223 near the second portion 230. The cup body 100 has a positioning groove 140 at the mounting opening 120 corresponding to the positioning protrusion 224. The positioning protrusion 224 is engaged in the positioning groove 140 to perform circumferential positioning of the seat body 200. It can be understood that the positioning protrusion 224 and the positioning groove 140 can also cooperate to perform axial positioning of the seat body 200.

[0054] In a further embodiment, the groove wall of the positioning groove 140 and the outer surface of the corresponding positioning protrusion 224 can be welded together, and the welding method can also be laser welding, so as to strengthen the connection between the seat 200 and the cup 100.

[0055] In other embodiments, the seat 200 may only have a raised edge 223 or only a positioning protrusion 224 as needed, as long as the positioning needs of the seat 200 are met.
