Description

Technical Field

[0001] This application relates to the field of atomizer technology, and in particular to an atomizer. Background Technology

[0002] An atomizer atomizes a matrix into an aerosol. The atomizer uses an atomizing core to convert the matrix within the liquid cup into an aerosol. The atomizing core has pins that extend beyond the liquid cup and connect electrically to the battery assembly. In related technologies, during atomizer assembly, the pins need to be sealed through the perforations using an adhesive dispensing process after extending beyond the liquid cup. This results in a complex and inefficient atomizer manufacturing process. Summary of the Invention

[0003] Embodiments of this application provide atomizers that simplify the atomizer assembly process.

[0004] This application provides an atomizer. The atomizer includes a housing, an atomizing component, and a battery assembly. The atomizing component is disposed within the housing. The atomizing component includes a liquid cup with a receiving space, and the liquid cup includes an integrally formed bottom wall and side walls. The liquid cup has an airflow channel, and an atomizing core with leads is disposed within the airflow channel. The bottom wall has a first through hole for the leads to pass through. The atomizing component also includes a wiring sealing structure, the leads passing through the first through hole and entering the wiring sealing structure, and the leads are electrically connected to the battery assembly.

[0005] Optionally, the bottom wall is also provided with a blind hole with an opening facing away from the receiving space; the bottom wall is also provided with a receiving groove, which is connected to the receiving space, a first through hole is provided at the bottom of the receiving groove, and a wiring sealing structure is provided in the receiving groove. The wiring sealing structure includes a second through hole, which is connected to the first through hole. The pin passes through the second through hole and the first through hole and then bends and extends into the blind hole.

[0006] Optionally, the atomizer also includes a circuit board disposed within the housing and positioned vertically above and below the atomizing assembly along the axial direction of the housing. The circuit board includes connecting electrodes that are inserted into blind holes and abut against pins to electrically conduct with the pins.

[0007] Optionally, an elastic membrane layer integrally formed with the wiring sealing structure is formed in the middle of the second through hole, and the pin pierces through the elastic membrane layer to pass through the second through hole.

[0008] Optionally, the atomizing assembly also includes a liquid reservoir disposed in a liquid cup, the liquid reservoir having an airflow channel, and an atomizing core disposed in the airflow channel; the bottom wall of the liquid cup has an air inlet, the air inlet communicating with the airflow channel, the atomizing core including an atomizing tube communicating with the airflow channel and extending to the air inlet; and a pin portion disposed inside the atomizing tube.

[0009] Optionally, a fastener is provided inside the atomizing tube, with the pin portion located between the fastener and the inner wall of the atomizing tube, and the fastener presses the pin tightly against the inner wall of the atomizing tube.

[0010] Optionally, a positioning tube is provided on the bottom wall extending toward the atomizing tube at the air inlet; the pin portion passes between the outer wall of the positioning tube and the inner wall of the atomizing tube, and extends to the first through hole.

[0011] Optionally, a positioning tube is provided on the bottom wall extending toward the atomizing tube at the air inlet. The tube wall of the positioning tube is provided with a wire hole communicating with the first through hole, and the pin extends to the first through hole through the wire hole.

[0012] Optionally, the atomizer core has two pins and two first through holes on the bottom wall, with the angle between the lines connecting the centers of the two first through holes and the center of the air inlet being less than 90 degrees.

[0013] Optionally, the battery assembly includes a battery electrically connected to the circuit board, the battery having battery electrodes, and the atomizer further includes an airflow sensor; the atomizer also includes a light guide base, which is mounted on one end of the housing near the battery assembly; an indicator light is provided on the side of the circuit board facing the battery; a light guide is also provided between the battery and the housing, which is used to guide the light from the indicator light to the light guide base.

[0014] The beneficial effects of this application are as follows: Unlike existing technologies, by setting a wiring sealing structure, the wiring sealing structure can seal the periphery of the pin when it passes through, thus preventing leakage of the atomizing matrix through the first through-hole. Furthermore, the gap between the periphery of the wiring sealing structure and the sidewall of the receiving groove can also be sealed by the interference fit between the wiring sealing structure and the receiving groove, thereby preventing leakage of the atomizing matrix through the first through-hole. Through the above methods, the sealing of the first through-hole can be achieved by the wiring sealing structure. The wiring sealing structure can be manufactured through other processes, and during atomizer assembly, it can be assembled as a separate component, positioned and moved by the assembly equipment, just like other components. This eliminates the need for adhesive application to seal the first through-hole during atomizer assembly, simplifying the atomizer assembly process and improving assembly efficiency and automation.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] See Figures 1 to 3 This application provides an atomizer 400, which includes an atomizing component 410, a battery component 420, a housing 430, a mouthpiece 440, and a base 450. The housing 430 has openings at both ends, allowing components such as the atomizing component 410, battery component 420, mouthpiece 440, and base 450 to be inserted into the housing 430 through the openings at either end. The atomizing component 410 and battery component 420 are disposed within the housing 430 and are vertically arranged along the axial direction of the housing 430. The mouthpiece 440 is mounted at the end of the housing 430 away from the battery component 420, and the base 450 is mounted at the other end of the housing 430. The mouthpiece 440 and base 450 cooperate with each other at both ends of the housing 430, thereby stably mounting the atomizing component 410 and battery component 420 within the housing 430.

[0026] Specifically, in some embodiments, the outer casing 430 can be made of metal or plastic, without specific limitations. The outer casing 430 can be processed with sandblasting or anodizing to give its surface a certain roughness, making it easier for the user to hold and improving its aesthetics. The inner surface of the outer casing 430 can also be roughened using sandblasting or anodizing, allowing for greater friction between the atomizing component 410 or the battery component 420 and the inner surface of the outer casing 430, thus increasing the stability of their installation. In other embodiments, the outer surface of the outer casing 430 can be coated with images or text through methods such as pasting, printing, or etching, allowing the outer casing 430 to display information about the atomizer 400 or its brand, facilitating user identification and use.

[0027] Optionally, in some embodiments, the diameter of the end of the housing 430 used for mounting the base 450 gradually decreases in the direction from the atomizing component 410 toward the battery assembly 420. This arrangement allows the interference fit between the base 450 and the housing 430 to gradually increase during installation, thereby stably mounting the base 450.

[0028] Specifically, the base 450 can be inserted into the end of the housing 430 before components such as the atomizing assembly 410, battery assembly 420, and mouthpiece 440. See also... Figure 2The outer casing 430 has a first end 4301 and a second end 4302. The first end 4301 is the end of the outer casing 430 near the atomizing component 410, and the second end 4302 is the end of the outer casing 430 used to mount the base 450. The base 450 is clearance-fitted to the first end 4301 of the outer casing 430, allowing the base 450 to be easily inserted into the outer casing 430 from the first end 4301 during installation. Further installation of the base 450 requires gradually pushing it towards the second end 4302 of the outer casing 430. In this design, the diameter of the second end 4302 gradually decreases in the direction away from the first end 4301. During the insertion of the base 450, as the diameter of the second end 4302 of the outer shell 430 gradually decreases, the fit between the base 450 and the outer shell 430 changes from a clearance fit to an interference fit, and the interference gradually increases. This ensures that after the base 450 is installed, it has sufficient interference with the second end 4302 of the outer shell 430 to stably mount the base 450 onto the outer shell 430. In summary, by using a clearance fit between the base 450 and the first end 4301 of the outer shell 430, and by setting the diameter of the second end 4302 of the outer shell 430 to gradually decrease, the assembly process of the base 450 is simplified. This allows for stable installation of the base 450 during the insertion process from the first end 4301 to the second end 4302, which is beneficial for improving the assembly efficiency and automation level of the atomizer 400. Furthermore, the base 450 is provided with an air intake structure, through which external gas can enter the housing 430 and then flow through the gaps between the battery components 420 and between the battery components 420 and the housing 430 to the atomizing component 410.

[0029] Combination Figures 4 to 6 In some embodiments, the atomizing assembly 410 includes a liquid cup 411 with a receiving space 411a, which is used to store the atomizing matrix or to contain an oil storage medium such as an oil storage component adsorbing the atomizing matrix. The liquid cup 411 includes an integrally formed bottom wall 4111 and a side wall 4112. The integral forming of the bottom wall 4111 and the side wall 4112 of the liquid cup 411 can reduce the number of parts in the atomizing assembly 410, thereby simplifying the assembly of the atomizer 400. Specifically, in related technologies, silicone rings are used to seal both ends of the liquid cup 411, but the integral forming of the bottom wall 4111 and the side wall 4112 of the liquid cup 411 itself has a good sealing effect. Therefore, by forming the bottom wall 4111 and the side wall 4112 integrally, the number of parts in the liquid cup 411 can be reduced, thereby simplifying the assembly process of the atomizer 400 and improving the assembly efficiency and automation level of the atomizer 400.

[0030] like Figure 5As shown, an atomizing core 412 is provided inside the liquid cup 411. The atomizing core 412 can atomize the atomizing matrix inside the liquid cup 411 by heating, thereby generating an aerosol that can be inhaled by the user. The atomizing core 412 has pins 4124, which can be electrically connected to a power source or a connecting electrode 423 to supply power to the atomizing core 412.

[0031] like Figure 7 As shown, in some embodiments, the bottom wall 4111 is provided with a first through hole 4111a through which the pin 4124 passes. The pin 4124 can protrude from the first through hole 4111a, thereby being electrically connected to the battery assembly 420. The first through hole 4111a can also limit the pin 4124 extending therein, thereby reducing the wobble of the pin 4124 when the atomizing assembly 410 is assembled with other components.

[0032] Furthermore, the bottom wall 4111 is also provided with a blind hole 4111b with its opening facing away from the atomizing core 412 (the blind hole 4111b refers to a through hole that connects the surface layer and the inner layer but does not penetrate the entire plate). In other words, the opening of the blind hole 4111b faces the battery assembly 420. After the lead 4124 passes through the first through hole 4111a, it is bent and extends into the blind hole 4111b. The battery assembly 420 includes a connecting electrode 423, which is inserted into the blind hole 4111b and abuts against the lead 4124 to achieve electrical conductivity with the lead 4124. After the lead 4124 is bent into the blind hole 4111b, it can easily cooperate with the connecting electrode 423. Specifically, through reasonable structural positioning design, during assembly, the connecting electrode 423 of the battery assembly 420 will naturally abut against the connecting electrode 423 located in the blind hole 4111b as it extends into the blind hole 4111b, without the need for additional connection operations.

[0033] In some embodiments of the above examples, the diameter of the connecting electrode 423 plus the diameter of the pin 4124 can be set to be larger than the diameter of the blind hole 4111b, so that the structure formed by the connecting electrode 423 and the pin 4124 can be interference-fitted with the blind hole 4111b. This allows the connecting electrode 423 and the pin 4124 to press against each other due to interference after the connecting electrode 423 is inserted into the blind hole 4111b, thereby improving the stability of the electrical contact between the pin 4124 and the connecting electrode 423.

[0034] Furthermore, in some embodiments, the extension length of the pin 4124 within the blind hole 4111b does not exceed the middle of the blind hole 4111b. This arrangement reduces the interference between the structure consisting of the connecting electrode 423 and the pin 4124 and the blind hole 4111b, thereby reducing the resistance when the connecting electrode 423 extends into the blind hole 4111b, allowing the connecting electrode 423 to extend into the blind hole 4111b more smoothly.

[0035] In other embodiments, the pin 4124 extends within the blind hole 4111b to the bottom of the blind hole 4111b and can be bent at the bottom. This configuration increases the contact area between the connecting electrode 423 and the pin 4124 after the connecting electrode 423 extends into the blind hole 4111b, thereby reducing the resistance of the contact between the pin 4124 and the connecting electrode 423 and improving the stability of their electrical contact. Optionally, the pin 4124 can be bent at the bottom of the blind hole 4111b to form a spring-loaded structure, so that when the connecting electrode 423 abuts against the spring-loaded structure after extending into the blind hole 4111b, the spring-loaded structure can increase the pressure between the spring-loaded structure and the connecting electrode 423 through elastic deformation, thereby improving the stability of the electrical contact between the connecting electrode 423 and the pin 4124.

[0036] The two different implementation methods described above depend on the assembly difficulty of the connecting electrode 423 extending into the blind hole 4111b during production and the requirement for the stability of the electrical connection between the connecting electrode 423 and the pin 4124. Those skilled in the art can adjust the depth of the pin 4124 extending into the blind hole 4111b according to the actual needs during production, thereby obtaining both appropriate assembly difficulty and appropriate electrical connection stability.

[0037] In some embodiments, the cross-sectional area of ​​the connecting electrode 423 gradually decreases in the direction from the battery assembly 420 toward the atomizing assembly 410. This arrangement allows the connecting electrode 423 assembly to form a frustoconical structure, thereby providing guidance as the connecting electrode 423 extends into the blind hole 4111b. Furthermore, it allows for a gradual increase in the interference fit between the structure formed by the connecting electrode 423 and the lead 4124 and the blind hole 4111b, further facilitating the insertion of the connecting electrode 423 into the blind hole 4111b. Optionally, the end of the connecting electrode 423 near the atomizing assembly 410 is chamfered.

[0038] In some embodiments, the cross-sectional area of ​​the portion of the pin 4124 within the blind hole 4111b gradually increases in the direction from the battery assembly 420 toward the atomizing assembly 410. This arrangement allows the outer edge of the pin 4124 to guide the connecting electrode 423 as it extends into the blind hole 4111b. Furthermore, as the connecting electrode 423 gradually extends into the blind hole 4111b, the size of the pin 4124 contacted by the end of the connecting electrode 423 gradually increases, and the interference fit between the structure formed by the connecting electrode 423 and the pin 4124 and the blind hole 4111b gradually increases, thereby improving the stability of the electrical contact between the connecting electrode 423 and the pin 4124.

[0039] In some embodiments, the diameter of the blind hole 4111b gradually decreases in the direction from the battery assembly 420 toward the atomizing assembly 410. This configuration allows the blind hole 4111b to guide the connecting electrode 423 as it extends into the blind hole 4111b. Furthermore, because the diameter of the blind hole 4111b decreases, the interference fit between the structure formed by the connecting electrode 423 and the lead 4124 and the blind hole 4111b gradually increases in the depth direction of the blind hole 4111b, thereby improving the stability of the electrical contact between the connecting electrode 423 and the lead 4124.

[0040] In some embodiments, the thickness of the region in the bottom wall 4111 where the first through hole 4111a and the blind hole 4111b are formed is greater than the thickness of the rest of the bottom wall 4111. This arrangement allows the blind hole 4111b to have sufficient depth, enabling the connection electrode 423 and the pin 4124 within the blind hole 4111b to fully abut, ensuring reliable electrical connection. The outer edge of the region where the first through hole 4111a and the blind hole 4111b are formed with the bottom surface of the rest of the bottom wall 4111 and part of the side wall 4112 of the liquid cup 411 to form a receiving space. This receiving space can accommodate some components of the battery assembly 420, such as the bracket 425, the airflow sensor 424, or the chip mentioned below. This improves the utilization rate of the internal space of the atomizer 400.

[0041] In summary, by setting the pin 4124 to pass through the first through hole 4111a, bend it, and then extend it into the blind hole 4111b, the assembly of the electrode 423 and the pin 4124 can be conveniently connected. This allows the assembly process of connecting the electrode 423 and the pin 4124 to be completed simply by positioning and moving, thus simplifying the assembly process of the atomizer 400. As a result, all of the above processes can be easily realized by CNC machinery, reducing the number of manual operations required. This is beneficial to improving the level of automated assembly of the atomizer 400, and enabling the manufacturing of the atomizer 400 to reduce costs and increase efficiency.

[0042] Combination Figures 5 to 7 In some embodiments, the atomizing assembly 410 further includes a liquid storage 4116 disposed within the accommodating space 411a. The liquid storage 4116 has an airflow channel 4116a, and the atomizing core 412 is disposed within the airflow channel 4116a. The atomizing core 412 can receive a portion of the atomizing matrix stored in the liquid storage 4116 and atomize it into an aerosol. The bottom wall 4111 of the liquid cup 411 has an air inlet 4111c, which communicates with the airflow channel 4116a. Gas can enter the airflow channel 4116a from the air inlet 4111c and drive the aerosol to flow within the airflow channel 4116a, ultimately flowing out of the atomizing assembly 410 for user use. Specifically, the liquid storage 4116 is a liquid storage cotton.

[0043] like Figure 4 and Figure 5 As shown, the liquid cup 411 also includes a detachable liquid cup cover 4113, which, together with the side wall 4112 and bottom wall 4111 of the liquid cup 411, forms a receiving space 411a. When the liquid cup cover 4113 is not installed, components such as the liquid storage 4116 can be installed into the receiving space 411a from one end of the liquid cup 411. After the liquid cup cover 4113 is installed, the bottom wall 4111 and the liquid cup cover 4113 can stably clamp the components such as the liquid storage 4116 in the receiving space 411a. The liquid cup cover 4113 is provided with an air outlet communicating with the airflow channel 4116a, through which the airflow in the airflow channel 4116a can flow out of the atomizing component 410. Optionally, a liquid suction element 4115 is also embedded on the side of the liquid cup cover 4113 away from the bottom wall 4111. Because the atomization of the atomizing matrix may be incomplete, and condensation may occur during the aerosol's flow, liquid residue may remain upon aerosol discharge. The liquid absorbent 4115 is designed to absorb this liquid, reducing residue and improving the user experience. Specifically, the liquid absorbent 4115 is absorbent cotton or other conventional absorbent materials.

[0044] In one embodiment, see Figure 4 and Figure 5The atomizing core 412 includes a heating element 4123, an oil guide 4122, and an atomizing tube 4121. The atomizing tube 4121 also has an opening connecting to the mouthpiece 440. The atomizing tube 4121 is sleeved around the outer periphery of the oil guide 4122, allowing the oil guide 4122 to contact the storage liquid 4116, enabling the atomizing matrix to be transferred from the storage liquid 4116 to the oil guide 4122. The oil guide 4122 is sleeved around the outer periphery of the heating element 4123. The oil guide 4122 can store a certain amount of atomizing matrix and guide a portion of the atomizing matrix to the portion of the oil guide 4122 that contacts the heating element 4123. The heating element 4123 can heat the atomizing matrix, thereby atomizing the atomizing matrix into an aerosol. The heating element 4123 has the aforementioned pins 4124, and the heating element 4123 is electrically connected to the connecting electrode 423 through the pins 4124. The atomizing tube 4121 is connected to the airflow channel 4116a and extends to the air inlet 4111c. The pin 4124 is located inside the atomizing tube 4121. One pin is directly connected to the battery, and the other should be connected to the microphone; otherwise, the microphone cannot be controlled. Alternatively, the other pin can be connected to a PCB board, which can then be used to connect the microphone.

[0045] In some embodiments, the first through-hole 4111a described above can be an air inlet 4111c. In other embodiments, the first through-hole 4111a is a through-hole independent of the air inlet 4111c, and the pin 4124 exits through the first through-hole 4111a instead of the air inlet 4111c. This arrangement prevents the pin 4124 from guiding the condensate in the airflow channel 4116a, thus preventing the condensate from flowing down the pin 4124 to the battery assembly 420.

[0046] In some embodiments, such as Figure 5 and Figure 6 As shown, a positioning tube 4114 extends from the air inlet 4111c into the atomizing tube 4121 on the bottom wall 4111. The hollow interior of the positioning tube 4114 allows airflow entering through the air inlet 4111c to pass through. The positioning tube 4114 extends into the atomizing tube 4121, thereby restricting the radial movement of the atomizing tube 4121, and further restricting the movement of the atomizing core 412. The liquid reservoir 4116 is sleeved on the outer periphery of the atomizing core 412, and the positioning tube 4114 can further restrict the movement of the liquid reservoir 4116 through the atomizing core 412.

[0047] It is understandable that the positioning tube 4114 can fix the pin 4124, and the pin 4124 can extend to the first through hole 4111a through various means, and then exit from the first through hole 4111a. For example, the pin 4124 can be partially inserted between the outer wall of the positioning tube 4114 and the inner wall of the atomizing tube 4121, and extend to the first through hole 4111a. Alternatively, the positioning tube 4114 can have a wire hole 4114a communicating with the first through hole 4111a, through which the pin 4124 extends to the first through hole 4111a.

[0048] The following example illustrates how the positioning tube 4114 fixes the pin 4124 and how the pin 4124 extends to the first through hole 4111a.

[0049] In some embodiments, the pin 4124 partially passes through the outer wall of the positioning tube 4114 and the inner wall of the atomizing tube 4121, and extends to the first through hole 4111a. In other words, the pin 4124 extends to the first through hole 4111a through the gap between the positioning tube 4114 and the atomizing tube 4121. With this arrangement, the pin 4124 can be squeezed by the atomizing tube 4121 and the positioning tube 4114, thereby increasing the stability of the extension of the pin 4124 and reducing the shaking of the pin 4124. Furthermore, since the pin 4124 passes through the outer wall of the positioning tube 4114 and the inner wall of the atomizing tube 4121, the positioning tube 4114 does not need to be drilled again to extend the pin 4124 to the first through hole 4111a, thereby simplifying the manufacturing process of the liquid cup 411. Furthermore, the fact that the pin 4124 passes between the outer wall of the positioning tube 4114 and the inner wall of the atomizing tube 4121 can be achieved through positioning and movement using CNC equipment, which helps to improve the level of automated assembly of the atomizer 400. Optionally, the outer periphery of the positioning tube 4114 is provided with a fine groove extending along the axial direction of the outer casing 430.

[0050] In other embodiments, the bottom wall 4111 extends into the atomizing tube 4121 from the air inlet 4111c. The wall of the positioning tube 4114 has a wire hole 4114a communicating with the first through hole 4111a. The lead 4124 extends through the wire hole 4114a to the first through hole 4111a. In other words, the bottom wall 4111 of the positioning tube 4114 and the liquid cup 411 forms a through hole that penetrates both of them. The lead 4124 can pass through the positioning tube 4114 and the bottom wall 4111 through the wire hole 4114a and the first through hole 4111a, and then bend and extend into the blind hole 4111b. With this configuration, since the positioning tube 4114 is located inside the atomizing tube 4121, the threading hole 4114a opened on the positioning tube 4114 is connected to the airflow channel 4116a, but not to the part of the accommodating space 411a that stores the atomizing matrix, thereby reducing the possibility of the atomizing matrix leaking from the threading hole 4114a.

[0051] Optionally, the wire hole 4114a and the first through hole 4111a can be coaxially arranged, and both can have the same or similar diameters. This allows the pin 4124 to pass through the receiving space 411a along the axis of the first through hole 4111a and the wire hole 4114a, thereby reducing the number of bends of the pin 4124 and facilitating the assembly of the pin 4124 with the liquid cup 411.

[0052] In other embodiments, the bottom wall 4111 extends a positioning tube 4114 towards the atomizing tube 4121 from the air inlet 4111c. The positioning tube 4114 has a threading hole 4114a in its wall. The lead 4124 passes through the threading hole 4114a and then bends to extend into the blind hole 4111b. This arrangement, since the positioning tube 4114 is located inside the atomizing tube 4121, and the threading hole 4114a on the positioning tube 4114 communicates with the airflow channel 4116a but not with the portion of the accommodating space 411a that stores the atomizing matrix, reduces the possibility of leakage of the atomizing matrix from the threading hole 4114a. Furthermore, the lead 4124 can pass through the accommodating space 411a along the axis of the threading hole 4114a, reducing the number of bends required and facilitating the assembly of the lead 4124 with the liquid cup 411.

[0053] In some embodiments, see Figure 7 The atomizing core 412 has two pins 4124, which can be connected to two connecting electrodes 423 respectively. The two connecting electrodes 423 can be a positive connecting electrode 423 and a negative connecting electrode 423 respectively. The bottom wall 4111 is provided with two first through holes 4111a, and the angles formed by the lines connecting the centers of the two first through holes 4111a to the center of the air inlet 4111c are respectively (see...). Figure 7In this case, α) is less than 120 degrees. In other words, the two first through holes 4111a on the bottom wall 4111 are positioned close to each other. This arrangement allows the distribution of the first through holes 4111a on the bottom wall 4111 to be more concentrated, thereby allowing the wiring of the pins 4124 to be more concentrated and reducing the space occupied inside the atomizer 400. Optionally, the angle between the lines connecting the centers of the two first through holes 4111a and the center of the air inlet 4111c is less than 90 degrees.

[0054] In some embodiments, combined with Figure 5 A fastener 414 is disposed inside the atomizing tube 4121. The fastener 414 is hollow and allows airflow to pass through. The pin 4124 is located between the fastener 414 and the inner wall of the atomizing tube 4121, and the fastener 414 presses the pin 4124 tightly against the inner wall of the atomizing tube 4121. In some embodiments, the outer periphery of the fastener 414 is provided with a fine groove extending along the axial direction of the outer casing 430 for aligning the pin 4124 and allowing the pin 4124 to pass through. This configuration allows the pin 4124 to be pressed against the inner wall of the atomizing tube 4121 by the fastener 414 inside the atomizing tube 4121 when the atomizing core 412 is not assembled with the liquid cup 411. This ensures that the pin 4124 has high stability and is not easily shaken when the atomizing core 412 is not assembled with the liquid cup 411. This facilitates the assembly of the atomizing core 412 with the liquid cup 411, that is, it facilitates the insertion of the pin 4124 into the first through hole 4111a and the insertion of the positioning tube 4114 into the atomizing tube 4121.

[0055] In related technologies, the pin 4124 of the atomizing core 412 in the atomizer 400 extends through the bottom wall 4111 of the liquid cup 411, thereby connecting to the connecting electrode 423. The pin 4124 passing through the bottom wall 4111 causes a perforation in the bottom wall 4111, and the gap between the perforation and the pin 4124 leads to leakage in the atomizing assembly 410. In related technologies, during the production of the atomizer 400, adhesive is applied to the perforation to seal it. However, the adhesive application process requires different equipment or fixtures than the assembly process, requiring the semi-finished product to be switched to different equipment. Therefore, using adhesive application for sealing makes the production process of the atomizer 400 more complex, hindering assembly efficiency and automation. To improve the above-mentioned technical problems, this application provides the following embodiments.

[0056] In some embodiments, combined with Figures 6 to 8The bottom wall 4111 of the liquid cup 411 has a receiving groove 4111d, which communicates with the receiving space 411a. A first through hole 4111a is located at the bottom of the receiving groove 4111d. A wiring sealing structure 413 is provided inside the receiving groove 4111d. The wiring sealing structure 413 has a second through hole 4131, which communicates with the first through hole 4111a. The pin 4124 passes through the second through hole 4131 and the first through hole 4111a, and then extends into the blind hole 4111b after being bent. The wiring sealing structure 413 is used to seal the periphery of the pin 4124. With this configuration, when the pin 4124 passes through the second through hole 4131, the wiring sealing structure 413 can seal the periphery of the pin 4124, thereby preventing the atomizing matrix from flowing through the second through hole 4131. Furthermore, the gap between the periphery of the wiring sealing structure 413 and the sidewall 4112 of the receiving groove 4111d can also be sealed by the interference fit between the wiring sealing structure 413 and the receiving groove 4111d, thereby preventing leakage of the atomizing matrix through the first through hole 4111a. In this way, the sealing of the first through hole 4111a can be achieved by the wiring sealing structure 413. The wiring sealing structure 413 can be manufactured through other processes, and during the assembly of the atomizer 400, the wiring sealing structure 413 can be assembled like other components, simply by positioning and moving the assembly equipment. This eliminates the need for a gluing process to seal the first through hole 4111a during the assembly of the atomizer 400, simplifying the assembly process and improving the assembly efficiency and automation level of the atomizer 400.

[0057] Optionally, based on the previous embodiment, the angle between the lines connecting the centers of the two first through holes 4111a and the center of the air inlet 4111c can be less than 120 degrees. This configuration allows the wiring sealing structure 413 to cover the two closely spaced first through holes 4111a with a smaller volume, forming two second through holes 4131.

[0058] The sealing of the pin 4124 by the trace sealing structure 413 can be implemented in a variety of ways. The following is an exemplary description of the implementation of the sealing of the pin 4124 by the trace sealing structure 413.

[0059] In some implementations, combined Figure 8An elastic film layer 4132, integrally formed with the wiring sealing structure 413, is formed in the middle of the second through hole 4131. The pin 4124 pierces through the elastic film layer 4132 to pass through the second through hole 4131. Specifically, during the forming of the wiring sealing structure 413, the elastic film layer 4132 is formed inside the second through hole 4131, but at this time, no perforation is provided on the elastic film layer 4132. During the assembly of the atomizer 400, when the pin 4124 extends into the second through hole 4131, it can pierce the elastic film layer 4132, thereby passing through the elastic film layer 4132. It should be noted that the process of the pin 4124 piercing the elastic film layer 4132 can be described by the following example: When the pin 4124 contacts the elastic film layer 4132, but has not yet pierced it, the pin 4124 will push the elastic film layer 4132 to produce elastic deformation. As pin 4124 continues to be gradually pushed, a gap will appear in the elastic membrane layer 4132. The size of this gap is smaller than the diameter of pin 4124. After the gap is formed, the elastic membrane layer 4132 around the gap will undergo elastic deformation under the pressure of pin 4124, thus allowing pin 4124 to pass through the gap. Therefore, the elastic membrane layer 4132 around the gap is pressed tightly against the periphery of pin 4124. So, after pin 4124 punctures the elastic membrane layer 4132 and passes through, the elastic membrane layer 4132 can seal the periphery of pin 4124.

[0060] In other embodiments, an elastomer or elastic film can be inserted into the first through hole 4111a, and the pin 4124 can be sealed around the pin by piercing the elastomer or elastic film.

[0061] In some embodiments, the diameter of the second through hole 4131 is smaller than the diameter of the pin 4124. Thus, after the pin 4124 extends into the second through hole 4131, the pin 4124 and the second through hole 4131 can achieve a sealing effect through an interference fit.

[0062] In some embodiments, the wiring sealing structure 413 is provided with an annular flange in the circumferential direction. Figure 8 (Shown but not labeled), the plane enclosed by the annular flange is perpendicular to the axial direction of the first through hole 4111a, and at least two annular flanges are spaced apart along the axial direction of the first through hole 4111a. This arrangement allows the annular flanges to be in an interference fit with the side wall 4112 of the receiving groove 4111d, thereby achieving the aforementioned sealing effect. Furthermore, it allows the peripheral side of the wiring sealing structure 413 to have a larger interference fit only in the portion with the annular flange against the side wall 4112 of the receiving groove 4111d; that is, not all parts of the side wall of the wiring sealing structure 413 are in an interference fit with the side wall 4112 of the receiving groove 4111d. This arrangement facilitates the assembly of the wiring sealing structure 413 into the receiving groove 4111d.

[0063] In some implementations, combined Figure 8 The pin 4124 passes through the gap between the outer wall of the positioning tube 4114 and the inner wall of the atomizing tube 4121, and extends to the second through hole 4131. In other words, the pin 4124 extends to the second through hole 4131 through the gap between the positioning tube 4114 and the atomizing tube 4121. With this arrangement, the pin 4124 can be squeezed by the atomizing tube 4121 and the positioning tube 4114, thereby increasing the stability of the pin 4124's extension and reducing the pin 4124's shaking. Furthermore, the fact that the pin 4124 passes through the gap between the outer wall of the positioning tube 4114 and the inner wall of the atomizing tube 4121 allows the positioning tube 4114 to extend the pin 4124 to the second through hole 4131 without the need for additional drilling, thus simplifying the manufacturing process of the liquid cup 411. Furthermore, the fact that the pin 4124 passes between the outer wall of the positioning tube 4114 and the inner wall of the atomizing tube 4121 can be achieved by positioning and moving the pin through a CNC machine, which is beneficial to improving the level of automated assembly of the atomizer 400.

[0064] In other embodiments, combined Figure 9 A positioning tube 4114 extends from the air inlet 4111c toward the atomizing tube 4121 on the bottom wall 4111. The positioning tube 4114 has a wire hole 4114a communicating with the second through hole 4131. The lead 4124 extends through the wire hole 4114a to the second through hole 4131. This arrangement, with the positioning tube 4114 located inside the atomizing tube 4121, and the wire hole 4114a communicating with the airflow channel 4116a but not with the portion of the accommodating space 411a that stores the atomizing matrix, reduces the possibility of leakage of the atomizing matrix from the wire hole 4114a.

[0065] In some embodiments, the battery assembly 420 is disposed within the housing 430 and is vertically positioned above and below the atomizing assembly 410 along the axial direction of the housing 430. This arrangement allows the atomizer 400 to have an elongated cylindrical shape, conforming to user grip habits and thus enhancing the user experience.

[0066] In some embodiments, combined with Figure 2 and Figure 3 The battery assembly 420 includes a circuit board 422, and a battery 421, an airflow sensor 424, and a connecting electrode 423, all electrically connected to the circuit board 422. The circuit board 422 is located between the battery 421 and the atomizing assembly 410. The airflow sensor 424 and the connecting electrode 423 are directly soldered onto the circuit board 422, thereby reducing the number of components requiring wiring within the atomizer 400 and improving assembly efficiency.

[0067] In some embodiments, the airflow sensor 424 is disposed on the side of the circuit board 422 facing the atomizing assembly 410. The circuit board 422 also has a first air passage through which airflow can pass via the airflow sensor 424, thereby enabling the airflow sensor 424 to control the opening or closing of the atomizing core 412 by detecting the air pressure generated by the airflow. After passing through the airflow sensor 424, the airflow can enter the airflow channel 4116a through the air inlet.

[0068] In some implementations, such as Figure 5 As shown, the circuit board 422 and the atomizing assembly 410 are also provided with a bracket 425. The bracket 425 has a through hole for the connecting electrode 423 to pass through, allowing the connecting electrode 423 to extend into the blind hole 4111b. The bracket 425 also has a clearance space for the airflow sensor 424. The clearance space allows the airflow sensor 424 to be housed within it, reducing the probability of it being corroded by condensate. The bracket 425 also has a second air passage through which airflow can flow directly into the airflow channel 4116a. The bracket 425 prevents any condensate or atomizing matrix from dripping directly onto the circuit board 422, avoiding short circuits or false starts.

[0069] In some embodiments, an indicator light 4222 is provided on the side of the circuit board 422 facing the battery 421. When the user inhales, the indicator light 4222 illuminates to indicate the operating status of the atomizer 400. The indicator light 4222 can be made visible to the user by emitting light through an opening in the housing 430.

[0070] In some embodiments, the atomizer 400 further includes a light guide base 450. In other words, the aforementioned base 450 is a light guide base 450 supported by a light-guiding material, installed on the end of the housing 430 near the battery assembly 420. The light emitted by the indicator light 4222 can illuminate the light guide base 450, allowing the user to observe the light guide base 450 and receive a prompt. Furthermore, a light guide 426 is also provided between the battery 421 and the housing 430, thereby guiding the light from the indicator light 4222 to the light guide base 450. Furthermore, the light guide base 450 is made of a transparent or translucent material, allowing light to pass through to the outside of the atomizer 400.

[0071] In some embodiments, the atomizer 400 further includes a mouthpiece 440, which is mounted on the end of the housing 430 near the atomizing assembly 410. The mouthpiece 440 has an air outlet channel 441, which communicates with an air outlet connected to the liquid cup cover 4113, thereby communicating with an airflow channel 4116a. Aerosol within the airflow channel 4116a can be discharged through the air outlet channel 441 for user use. Optionally, a liquid suction element 4115 is embedded on the side of the wiring sealing structure 413 near the mouthpiece 440 facing the mouthpiece 440. Since the atomization of the atomizing matrix may be incomplete, and condensation may occur during the flow of the aerosol, liquid residue may remain when the aerosol is discharged from the air outlet. The liquid suction element 4115 can absorb the liquid to reduce liquid residue in the air outlet channel 441, thereby improving the user experience.

[0072] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
