Description

Technical Field

[0001] The invention relates to the technical field of atomizers, and in particular to an atomizer and a sealing process thereof. Background Art

[0002] In the prior art, the outer wall of the base of the atomizer is usually provided with an assembly groove for placing a silicone ring. When assembling the base of the atomizer and the oil cup, a silicone ring is first installed in the assembly groove, and then the base equipped with the silicone ring is inserted into the oil cup. The interference fit between the silicone ring and the inner wall of the oil cup is used to seal the oil cup and prevent the atomizer from leaking oil. However, the installation process of the silicone ring at the assembly groove usually needs to be completed manually, and because the silicone ring is an elastic element, when inserting the base equipped with the silicone ring into the oil cup, the silicone ring is very likely to be separated from the assembly groove due to friction between the inner wall of the oil cup, resulting in assembly failure and poor assembly.

[0058] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0059] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0060] Embodiment 1

[0061] like Figures 1 to 17 As shown, it is an atomizer of embodiment 1 of the present invention, including an oil cup 30, an atomizing body 10 and a base 20. The atomizing body 10 is installed in the oil cup 30. A liquid flow channel a and a gas flow channel b are formed between the atomizing body 10 and the oil cup 30. The liquid flow channel a and the gas flow channel b are independent of each other. The atomizing body 10 can atomize the atomized liquid in the liquid flow channel a to form gas, and discharge the atomized gas into the gas flow channel b.

[0062] The base 20 is connected to the atomizing body 10 , and the base and the oil cup are sealed by laser welding.

[0063] The atomizer forms a liquid flow channel a and a gas flow channel b that are independent of each other between the atomizing body 10 and the oil cup 30. The atomized liquid in the liquid flow channel a can be atomized to form gas through the atomizing body, and the atomized gas is released into the gas flow channel b to realize the atomization process. The base 20 and the oil cup 30 are sealed by laser welding, which can reduce the use of silicone rings or other material sealing rings in the prior art while ensuring the sealing performance, and reduce the manual assembly time. In addition, it can also avoid friction between the base 20 and the inner wall of the oil cup 30, and improve assembly efficiency and assembly qualification rate.

[0064] In addition, laser welding has the following advantages:

[0065] (1) The welding process does not generate vibration, so it will not affect electronic components;

[0066] (2) Only the welding position is heated and no impact is caused on other positions;

[0067] (3) The welding process does not produce any dust particles, and the welding cleanliness is high;

[0068] (4) Through rapid fixture replacement and programming, different products can be switched for welding;

[0069] (5) It can reach a strength close to that of the parent material, with good welding firmness and sealing;

[0070] (6) The laser energy is stable and the welding stability is good.

[0071] In one embodiment, the wavelength of the laser used for the laser welding is 808nm-1100nm. The light transmittance of the position where the oil cup 30 and the base 20 are laser welded is greater than 20% to ensure that the laser welding can be effectively performed.

[0072] In a specific embodiment, the laser welding can be laser penetration welding or laser splicing welding. If the laser welding is laser penetration welding, the light-transmitting material needs to be located on the side of the light-absorbing material facing the laser light source, and the light transmittance of the light-transmitting material needs to be greater than 20%. It can be understood that if laser penetration welding is used between the oil cup 30 and the base 20, one of the oil cup 30 and the base 20 needs to be a light-transmitting material, and the other needs to be a light-absorbing material, and the light-transmitting material needs to meet the light transmittance requirement (the light transmittance needs to be greater than 20%).

[0073] It should be noted that if the oil cup 30 and the base 20 are both plastic parts, the oil cup 30 and the base 20 can only be welded by laser penetration welding, and cannot be welded by laser splicing welding. This is because plastic has poor fluidity. If laser splicing welding is used, the welding strength and appearance cannot meet the requirements.

[0074] According to the different relative positions of the two plastic welded parts, they can be divided into stacking and annular sleeve. When laser penetration welding is adopted, the two stacked plastic welded parts need to be in plane-to-plane contact, so that the light-transmitting material is stacked on the light-absorbing material, the laser is set on the side of the light-transmitting material facing away from the light-absorbing material, and the thickness of the light-transmitting layer of the light-transmitting material is 0.5mm-3mm, and the width of the laser weld is 0.5mm-5mm. In addition, if a boss is formed on the light-absorbing material, a groove is formed on the light-absorbing material accordingly, when the boss and the groove are plugged and laser welded, it is necessary to ensure that the distance between the bottom surface of the boss and the bottom surface of the light-absorbing material (i.e. the collapse allowable space) is 0.2mm-1mm, and the distance between the outer wall of the boss and the inner wall of the groove (i.e. the overflow area) is 0.2mm-1mm; and for the two plastic welded parts in annular sleeves, it is necessary to ensure the interference fit between the light-transmitting material and the light-absorbing material (the interference amount is 0mm-0.1mm), and the internal expansion force of the material during welding can complete the required compression process.

[0075] It can be understood that when the oil cup 30 and the base 20 are both plastic parts, if the stacking position of the oil cup 30 and the base 20 is laser welded, the oil cup 30 and the base 20 need to be in plane-to-plane contact; if the annular sleeve position of the oil cup 30 and the base 20 is laser welded, it is necessary to ensure the interference fit of the oil cup 30 and the base 20, and at the same time, the oil cup 30 is made of a light-transmitting material with a light transmittance greater than 20%.

[0076] Furthermore, laser welding experiments were conducted on combinations of plastics of different colors (including transparent, black, white and colored, where colored refers to colors other than transparent, black and white). The experiments showed that: when the color combination is a combination of transparent and black, welding is possible; when the color combination is a combination of black and black, a combination of colored and black, or a combination of transparent and transparent, welding is possible if the transmittance requirements are met; when the color combination is a combination of white and white, or a combination of colored and colored, welding is not possible.

[0077] Furthermore, laser welding tests were conducted on welding combinations of different light-absorbing materials and light-transmitting materials, wherein both the light-absorbing material and the light-transmitting material were plastic materials. The test results are shown in Table 1 below:

[0078]

[0079] In Table 1, a means very suitable for laser welding, b means welding is possible (need to be tested), and c means welding is not possible. When performing actual laser welding, the combination a in Table 1 is preferred, such as the combination of light-absorbing material PE-LD and light-transmitting material PE-LD.

[0080] In one embodiment, in order to ensure effective laser welding and avoid interference from other factors, no interference structure is provided at the position where the oil cup 30 and the base 20 are laser welded. The interference structure includes chamfers, fillets, welding ribs, a T-shaped structure whose partial cross-sectional area is smaller than the laser surface area, and a shielding structure that can partially shield the laser.

[0081] Specifically, chamfers or fillets cannot be provided because: when there are chamfers or fillets in the welding area, refraction will occur during the laser penetration process, resulting in the inability to effectively heat the required welding area, and the welding effect will be poor. Welding ribs cannot be provided because: the presence of welding ribs will cause the contact surface between the oil cup 30 and the base 20 to become smaller, heat transfer is difficult, and the welding strength becomes lower. A T-shaped structure with a partial cross-sectional area smaller than the laser surface area cannot be provided because: a T-shaped structure with a partial cross-sectional area smaller than the laser surface area will cause the laser to refract multiple times, resulting in the laser being unable to heat the underlying welding area; to overcome this problem, the width of the T-shaped structure can be appropriately increased. A shielding structure that can partially shield the laser (such as a Z-shaped structure) cannot be provided because: the shielding structure will block the laser and affect the welding effect.

[0082] In one embodiment, Figures 4 to 15As shown, the atomizer body 10 includes a closure 1, a closure seal 4, an atomizer core 2 and a core seal 3. The atomizer core 2 is provided with a liquid suction surface 21 and an atomization surface 22. The core seal 3 is sealingly sleeved on the atomizer core 2, and the liquid suction surface 21 and the atomization surface 22 are exposed from the core seal 3.

[0083] The closure member 1 is clamped on the base 20, and the sealing member 4 is sealed between the oil cup 30 and the closure member 1. The closure member 1 is provided with a liquid inlet channel a1 and a mist outlet channel b1, and atomized liquid can flow through the liquid inlet channel a1.

[0084] The core seal 3 is disposed in the closure 1 and between the closure 1 and the base 20. The liquid inlet channel a1 is connected to the liquid suction surface 21 to form a main liquid flow path, thereby realizing the flow of the atomized liquid inside the atomizing body 10. An atomizing cavity b2 is formed between the atomizing surface of the atomizing core, the core seal and the base. The atomizing cavity b2 is connected between the atomizing surface 22 and the mist outlet channel b1 to form a main gas flow path, thereby realizing the flow of the atomized gas inside the atomizing body 10.

[0085] In one embodiment, the closure member 1 , the closure seal 4 , the atomizer core 2 and the core seal 3 together with the base 20 form an atomizer sealing structure of the atomizer.

[0086] In one embodiment, Figures 4 to 6 As shown, the core seal 3 is sealed and inserted on the base 20 , and the closure 1 is sealed and inserted on the core seal 3 .

[0087] When the atomizer body 10 and the base 20 are installed, the core seal 3 can be firstly sealed and sleeved on the atomizer core 2, and then the core seal 3 can be sealed and plugged on the base 20, and finally the closure 1 can be sealed and plugged on the core seal 3 and clamped on the base 20 to achieve the installation of the atomizer body 10 and the base 20. This installation method uses a sealed plug-in method to achieve the installation connection between the core seal 3, the base 20 and the closure 1, and the components can be limited horizontally, which effectively prevents the lateral dislocation between the components of the atomizer when it is bumped, and avoids the occurrence of liquid leakage caused by lateral dislocation.

[0088] In one embodiment, if Fig.14 and Fig.15As shown, a liquid suction port 31 corresponding to the position of the liquid suction surface 21 and an atomization port 32 corresponding to the position of the atomization surface 22 are formed on the core seal 3, the liquid inlet channel a1 is connected with the liquid suction surface 21 through the liquid suction port 31 to form the main liquid flow path; the atomization chamber b2 is connected with the atomization surface 22 through the atomization port 32 to form the main gas flow path.

[0089] Furthermore, a sealing cavity 35 is formed on the core seal 3 , and the sealing cavity 35 is connected between the liquid suction port 31 and the atomization port 32 . When the core seal 3 is sealingly sleeved on the atomization core 2 , the atomization core 2 is sealed and inserted into the sealing cavity 35 .

[0090] In one embodiment, if Fig.14 and Fig.15 As shown, the core seal 3 includes a core seal body part 33 and a core seal connecting ear part 34 connected to the core seal body part 33, and the core seal body part 33 is sealingly sleeved on the atomizing core 2. Specifically, the core seal connecting ear part 34 is connected to the side of the core seal body part 33 facing the base 20.

[0091] Furthermore, if Fig.16 and Fig.17 As shown, a base plug hole 201 is provided on the side of the base 20 facing the atomizer core 2 , and the core sealing connection ear portion 34 is partially sealed and plugged into the base plug hole 201 to achieve plug-in connection between the core seal 3 and the base 20 .

[0092] Furthermore, in order to realize its sealing function, the core seal 3 is preferably an elastic seal made of silicone or other materials, and the core seal 3 can be an integrated silicone member. It can be understood that when the core sealing connection ear 34 is partially sealed and plugged into the base socket 201, in order to ensure the stability of the plugging, the core sealing connection ear 34 will be plugged with the base socket 201 through interference.

[0093] In one embodiment, if Fig.14 and Fig.15 As shown, the core body sealing connection ear portion 34 is provided with a plurality of them. When each of the core body sealing connection ear portions 34 is pulled in a direction away from the core body sealing body portion 33, the core body sealing body portion 33 undergoes elastic deformation, so that the atomization core 2 can be inserted into the sealing cavity 35 from the atomization port 32, and the atomization surface 22 of the atomization core 2 can be exposed at the atomization port 32, and the liquid suction surface 21 of the atomization core 2 can be exposed at the liquid suction port 31.

[0094] When the core seal 3 is sealed and connected with the atomizer core 2, the core seal connection ear 34 can be pulled outward (i.e., in the direction away from the core seal body 33) to elastically deform the end of the core seal body 33 forming the atomization port 32, so that the atomizer core 2 can be inserted into the sealed cavity 35 from the atomization port 32. After the atomizer core 2 is fully inserted into the sealed cavity 35, the core seal connection ear 34 is released, so that the core seal body 33 can be restored to its initial shape under the action of its own elastic force, and the entire installation process is completed. After the installation is completed, the atomization surface 22 of the atomizer core 2 will be exposed to the atomization port 32, and the liquid suction surface 21 of the atomizer core 2 will be exposed to the liquid suction port 31, thereby avoiding affecting the function of the atomizer core 2. The installation process can be carried out by automated equipment, and the installation of the atomizer core 2 can be realized by only pulling the core seal connection ear 34 outward by the automated equipment, and the installation is efficient and fast.

[0095] Further, in the illustrated embodiment, two core sealing connection ears 34 are provided, and the two core sealing connection ears 34 are respectively provided on opposite sides of the core sealing body 33. Preferably, the two core sealing connection ears 34 are respectively located on opposite sides along the length direction of the core sealing body 33 to enhance the installation stability and prevent the core seal 3 from being displaced relative to the base 20 in a direction perpendicular to the axis of the atomizer.

[0096] In one embodiment, if Fig.14 and Fig.15 As shown, the core sealing connecting ear portion 34 includes a sealing socket section 341 and a sealing plug-in section 342. The sealing socket section 341 is connected between the core sealing body portion 33 and the sealing plug-in section 342. The sealing plug-in section 342 is sealingly plugged into the base socket 201 to achieve the connection between the core seal 3 and the base 20.

[0097] Furthermore, the sealing socket section 341 is provided with a sealing socket 3411 . The provision of the sealing socket 3411 can facilitate pulling of the core sealing connection ear 34 , and can also be used for connection between the core seal 3 and the closure 1 .

[0098] Specifically, when the sealing plug hole 3411 is used for connecting the core seal 3 and the closure member 1, Figures 8 to 10As shown, the closure member 1 includes a closed body portion 11 and a closed connection portion 12 connected to the closed body portion 11, and the closed body portion 11 is provided with the liquid inlet channel a1 and the mist outlet channel b1. The closed connection portion 12 is connected to the side of the closed body portion 11 facing the base 20, and the closed connection portion 12 is partially sealed and inserted in the sealed insertion hole 3411.

[0099] Furthermore, the core seal 3 is preferably an elastic seal made of silicone or other materials. When the closed connection part 12 is partially sealed and plugged into the sealing plug hole 3411, in order to ensure the stability of the plugging, the closed connection part 12 will be plugged into the sealing plug hole 3411 with interference fit.

[0100] In one embodiment, if Fig.14 and Fig.15 As shown, the sealing hole 3411 is arranged on the side of the sealing hole section 341 facing away from the sealing plug section 342, and the axis of the sealing hole 3411 is parallel to the axis of the core sealing main body 33, so as to facilitate the pulling of the core sealing connecting ear 34 and the fitting connection between the core seal 3 and the closure 1.

[0101] In one embodiment, if Fig.14 and Fig.15 As shown, the outer wall of the core seal 3 is provided with a core sealing convex ring 331, and the core sealing convex ring 331 elastically abuts against the closed connecting portion 12 of the closure member 1, thereby further achieving the sealing between the core seal 3 and the closure member 1. At the same time, the setting of the core sealing convex ring 331 can also act in reverse on the atomizer core 2, so that the sealing connection between the atomizer core 2 and the core seal 3 is tighter, thereby enhancing the sealing effect.

[0102] In one embodiment, if Fig.14 and Fig.15 As shown, a first step 36 is formed on the core sealing body 33 at a position where the sealing cavity 35 is connected to the atomizing port 32. The inner diameter of the first step 36 is smaller than the inner diameter of the sealing cavity 35, thereby axially limiting the atomizing core 2, so that after the atomizing core 2 is fully inserted into the sealing cavity 35 and the core sealing connecting ear 34 is loosened, the first step 36 cannot be removed from the core sealing member 3 from the atomizing port 32.

[0103] In one embodiment, if Fig.14 and Fig.15As shown, a second step 37 is formed on the core sealing body 33 at a position where the sealing cavity 35 is connected to the liquid suction port 31, and the inner diameter of the second step 37 is smaller than the inner diameter of the sealing cavity 35, thereby axially limiting the atomizer core 2 to prevent the atomizer core 2 from being over-installed when inserted into the sealing cavity 35, thereby penetrating the core seal 3.

[0104] In one embodiment, if Figures 8 to 10 As shown, the closed connection portion 12 includes a closed clamping section 121 and a closed plug-in section 122, wherein the closed clamping section 121 is connected between the closed body portion 11 and the closed plug-in section 122, and the closed plug-in section 122 is plugged into the sealing insertion hole 3411 to achieve the connection between the closing member 1 and the core sealing member 3. The closed clamping section 121 is clamped with the base 20 to achieve the connection between the closing member 1 and the base 20.

[0114] The atomizer core 2 has a wavy end surface 211 formed on the liquid absorption surface 21, so that the liquid absorption surface 21 is not parallel to the atomization surface 22. Under the premise of not weakening the strength of the atomizer core 2, the contact area between the atomized liquid and the atomization core 2 is increased, that is, the area of ​​the liquid absorption surface 21 is increased, so that the atomized liquid can quickly and timely reach the atomization surface 22, avoiding the phenomenon of dry burning of the atomization surface due to lack of atomized liquid, and at the same time improving the strength of the atomizer core 2.

[0115] Furthermore, if Figures 11 to 13 As shown, the atomizing core 2 is provided with a groove 24 formed by the liquid absorption surface 21 being sunken toward the atomizing surface 22 , and the bottom of the groove 24 is formed with the wavy end surface 211 .

[0116] By arranging the groove 24 on the atomizer core 2 and forming the wavy end surface 211 at the bottom of the groove 24 , the contact area between the atomizer liquid and the atomizer core 2 is further increased, so that the atomizer liquid can quickly and timely reach the atomization surface 22 , thereby avoiding the phenomenon of dry burning of the atomization surface due to lack of atomizer liquid, and at the same time improving the strength of the atomizer core 2 .

[0119] In one embodiment, Figures 11 to 13 As shown, the side wall 241 of the groove 24 is not vertically arranged with respect to the horizontal end surface 212 to further increase the contact area between the atomized liquid and the atomizing core 2, so that the atomized liquid can quickly and timely reach the atomizing surface 22, thereby avoiding the phenomenon of dry burning of the atomizing surface due to lack of atomized liquid, and at the same time improving the strength of the atomizing core 2.

[0120] In one embodiment, if Figures 11 to 13 As shown, the atomizing surface 22 of the atomizing core 2 is provided with a heating element 23 .

[0121] Furthermore, if Figure 5 and Fig.17 As shown, the atomizing body 10 further includes a conductive sheet 5, which is embedded in the base, one end of which is exposed from the base 20, and the other end of which is electrically connected to the heating element 23. The heating element 23 is energized through the conductive sheet 5, so that the heating element 23 generates heat to realize the atomizing function.

[0122] Preferably, the heating element 23 includes a plurality of heating ends 231 and a heating body 232 connected between the plurality of heating ends 231 , and the heating body 232 is disposed on the atomizing surface 22 of the atomizing core 2 in a serpentine shape.

[0123] Furthermore, if Figure 5 and Fig.17 As shown, one end of the conductive sheet 5 electrically connected to the heating element 23 is vertically abutted against the heating element 23. To prevent damage between the conductive sheet 5 and the heating element 23 due to rigid abutment, a plurality of protrusions 38 are provided on the side of the core sealing body 33 facing away from the sealing plug section. The protrusions 38 can abut against the closure member 1 along the axial direction of the atomizer. The elastic abutment between the protrusions 38 and the closure member 1 can effectively reduce the force of the rigid abutment between the conductive sheet 5 and the heating element 23, thereby avoiding damage due to rigid abutment.
