Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomizers, in particular to an atomizer. BACKGROUND

[0002] An atomizer can atomize an atomization substrate into an aerosol. The atomizer converts the atomization substrate in an atomization shell into an aerosol through an atomization core. The atomization core has a pin, and the pin needs to be wired in the atomizer. How to make the pin pass out of the atomization channel where the atomization core is located and be connected with an electrical component is a problem to be solved. SUMMARY

[0003] Embodiments of the present application provide an atomizer, which can make the pin pass out of the atomization channel where the atomization core is located and be connected with an electrical component.

[0004] An atomizer is provided by embodiments of the present application. The atomizer comprises a shell, an atomization assembly and a power supply assembly. The atomization assembly is arranged in the shell, and the atomization assembly comprises an atomization shell having a containing space. The atomization shell comprises a bottom wall and a side wall arranged integrally. An atomization core is arranged in an atomization channel of the atomization shell, and the atomization core has at least two pins. The bottom wall is provided with two first through holes for the two pins to pass through respectively and an air inlet hole. The bottom wall is further provided with a blind hole with an opening facing away from the containing space. The pins are bent to extend into the blind hole after passing through the first through holes, and the at least two pins are bent towards a similar direction. The power supply assembly is arranged in the shell, and the power supply assembly comprises two conductive terminals which extend into the blind hole and abut against the pins.

[0005] The beneficial effects of the present application are as follows: Different from the prior art, the pins are electrically connected with the conductive terminals after passing through the first through holes, so that the pins can pass out of the atomization channel where the atomization core is located and be connected with an electrical component. The two pins are bent towards a similar direction, so that the features of the bottom wall corresponding to the pins can be arranged close to each other. The features related to the pins can be distributed more concentratedly on the bottom wall, so that the wiring of the pins can be more concentrated, and the occupation of the internal space of the atomizer can be reduced. Since the features of the blind hole require a thicker bottom wall, the concentrated distribution of the blind holes can also reduce the thickness of the thicker part of the bottom wall, which is beneficial to improve the space utilization and reduce the weight of the atomizer.

[0014] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of protection of the present application.

[0015] Reference is made to Figures 1 to 3The present application provides an atomizer 400, which comprises an atomizing assembly 410, a power supply assembly 420, a housing 430, a suction member 440 and a seat 450. The housing 430 is open at both ends, so that the components such as the atomizing assembly 410, the power supply assembly 420, the suction member 440 and the seat 450 can be loaded into the housing 430 from the open ends of the housing 430. The housing 430 can be made of metal material or plastic material, which is not specifically limited herein. The atomizing assembly 410 and the power supply assembly 420 are arranged in the housing 430, and the atomizing assembly 410 and the power supply assembly 420 are arranged in the axial direction of the housing 430. The suction member 440 is mounted at one end of the housing 430 away from the power supply assembly 420, and the seat 450 is mounted at the other end of the housing 430. The suction member 440 and the seat 450 are matched at the two ends of the housing 430, so as to stably mount the atomizing assembly 410 and the power supply assembly 420 in the housing 430. A user can hold the housing 430 to pick up or put down the atomizer 400. The seat 450 is further provided with an air inlet structure, and external air can enter the housing 430 from the air inlet structure, and then flow through the gaps between the battery assemblies 420 and between the battery assemblies 420 and the housing 430 to the atomizing assembly 410.

[0016] Optionally, in some embodiments, the diameter of the end of the housing 430 for mounting the seat 450 gradually decreases in the direction of the atomizing assembly 410 towards the power supply assembly 420. In this way, the interference amount between the seat 450 and the housing 430 can gradually increase during the mounting process, so as to stably mount the seat 450.

[0017] Specifically, the seat body 450 can be assembled into the shell 430 in advance of the components such as the atomization assembly 410, the power supply assembly 420, and the suction member 440. The shell 430 has a first end and a second end, the first end being the end of the shell 430 close to the atomization assembly 410, and the second end being the end of the shell 430 for mounting the seat body 450. The seat body 450 is in clearance fit with the first section of the shell 430, so that the seat body 450 can be conveniently assembled into the shell 430 from the first end of the shell 430. When the seat body 450 is further assembled, the seat body 450 needs to be gradually pushed into the second end of the shell 430. The diameter of the second end gradually decreases in the direction away from the first end. During the process of pushing the seat body 450, the seat body 450 and the shell 430 will change from clearance fit to interference fit, and the interference amount gradually increases, so that after the seat body 450 is mounted in place, the seat body 450 can generate sufficient interference with the second end of the shell 430 to stably mount the seat body 450 in the shell 430. In summary, by clearance fit of the seat body 450 with the first end of the shell 430, and by setting the diameter of the second end of the shell 430 to gradually decrease, the assembly process of the seat body 450 can be simplified, and the stable installation of the seat body 450 can be realized during the process of pushing from the first end to the second end, which is conducive to improving the assembly efficiency and automation level of the atomizer 400.

[0018] In combination Figures 4 to 6 In some embodiments, the atomization assembly 410 includes an atomization shell 411 having a containing space 411a for storing an atomization substrate or a storage medium such as an oil storage member having the atomization substrate adsorbed thereon. The atomization shell 411 includes an integrally formed bottom wall 4111 and a side wall 4112. The integrally formed bottom wall 4111 and side wall 4112 of the atomization shell 411 can reduce the number of parts of the atomization assembly 410, thereby simplifying the assembly of the atomizer 400. Specifically, the related art uses a silica gel ring to achieve sealing at both ends of the atomization shell 411, but the integrally formed bottom wall 4111 and side wall 4112 of the atomization shell 411 itself has good sealing effect. Therefore, the integrally formed bottom wall 4111 and side wall 4112 can reduce the number of parts of the atomization shell 411, thereby simplifying the process steps of the assembly of the atomizer 400, and being conducive to improving the assembly efficiency and automation level of the atomizer 400.

[0019] As Figure 5 shown, the atomization shell 411 is provided with an atomization core 412, which can atomize the atomization substrate in the atomization shell 411 by heating to generate aerosol that can be inhaled by a user. The atomization core 412 has a pin 4124 that can be electrically connected to a power supply or a conductive terminal 423 to supply power to the atomization core 412.

[0020] As Figure 6 and 7 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 pass out of the first through hole 4111a to be electrically connected with the power supply assembly 420. The first through hole 4111a can also function as a limiting position for the pin 4124 inserted therein, so that when the atomization assembly 410 is assembled with other components, the shaking of the pin 4124 is reduced.

[0021] Further, the bottom wall 4111 is also provided with a blind hole 4111b (the blind hole 4111b refers to a through hole connecting the surface layer and the inner layer without penetrating the whole plate) with an opening facing away from the atomization core 412, in other words, the opening of the blind hole 4111b faces the power supply assembly 420. The pin 4124 passes out of the first through hole 4111a and is bent to extend into the blind hole 4111b. The power supply assembly 420 includes a conductive terminal 423, which is inserted into the blind hole 4111b and abuts against the pin 4124 to electrically conduct with the pin 4124. The pin 4124 bent into the blind hole 4111b can be very convenient to cooperate with the conductive terminal 423. Specifically, during assembly, the conductive terminal 423 of the power supply assembly 420 will naturally abut against the conductive terminal 423 provided in the blind hole 4111b during the process of extending into the blind hole 4111b, without the need for additional connection operations.

[0022] In some embodiments of the above embodiments, the diameter of the conductive terminal 423 plus the diameter of the pin 4124 can be greater than the hole diameter of the blind hole 4111b, so that the structure composed of the conductive terminal 423 and the pin 4124 can be interference fit with the blind hole 4111b, and then after the conductive terminal 423 extends into the blind hole 4111b, the conductive terminal 423 and the pin 4124 can be pressed against each other due to the interference, so as to improve the stability of the electrical contact between the pin 4124 and the conductive terminal 423.

[0023] Further, in some embodiments, the extension length of the pin 4124 in the blind hole 4111b does not exceed the middle portion of the blind hole 4111b. In this way, the structure formed by the conductive terminal 423 and the pin 4124 and the blind hole 4111b can have less interference, so that when the conductive terminal 423 is extended into the blind hole 4111b, the resistance of the pin 4124 is reduced, and the conductive terminal 423 can be more smoothly extended into the blind hole 4111b. In other embodiments, the pin 4124 extends to the bottom of the blind hole 4111b and can be bent at the bottom. In this way, the contact area between the conductive terminal 423 and the pin 4124 can be increased after the conductive terminal 423 is extended into the blind hole 4111b, so that the resistance of the pin 4124 and the conductive terminal 423 is reduced, and the stability of the electrical contact between the two is improved. Alternatively, the pin 4124 can be bent at the bottom of the blind hole 4111b to form a spring structure, so that when the conductive terminal 423 is extended into the blind hole 4111b and abuts against the spring structure, the spring structure can increase the pressure between the spring structure and the conductive terminal 423 by elastic deformation, thereby improving the stability of the electrical contact between the conductive terminal 423 and the pin 4124.

[0024] In some embodiments, the cross-sectional area of the conductive terminal 423 gradually decreases in the direction of the power supply assembly 420 towards the atomization assembly 410. In this way, the conductive terminal 423 can form a frustum structure, so that the conductive terminal 423 can be guided during the process of extending into the blind hole 4111b. And the interference between the structure formed by the conductive terminal 423 and the pin 4124 and the blind hole 4111b gradually increases, which further facilitates the extension of the conductive terminal 423 into the blind hole 4111b. Alternatively, the conductive terminal 423 can be provided with a chamfer at the end close to the atomization assembly 410.

[0025] In some embodiments, the cross-sectional area of the pin 4124 gradually increases in the direction of the power supply assembly 420 towards the atomization assembly 410. In this way, the outer edge of the pin 4124 can guide the conductive terminal 423 during the process of extending into the blind hole 4111b. And during the process of gradually extending into the blind hole 4111b, the size of the pin 4124 contacted by the end of the conductive terminal 423 gradually increases, and the interference between the structure formed by the conductive terminal 423 and the pin 4124 and the blind hole 4111b gradually increases, thereby improving the stability of the electrical contact between the conductive terminal 423 and the pin 4124.

[0026] In some embodiments, the diameter of the blind hole 4111b gradually decreases in the direction of the power supply assembly 420 towards the atomization assembly 410. In this way, the blind hole 4111b can guide the conductive terminal 423 during the process of the conductive terminal 423 extending into the blind hole 4111b. Moreover, since the diameter of the blind hole 4111b decreases, the interference between the structure composed of the conductive terminal 423 and the pin 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 conductive terminal 423 and the pin 4124.

[0027] In some embodiments, the thickness of the region of the bottom wall 4111 in which the first via hole 4111a and the blind hole 4111b are formed is greater than the thickness of other parts of the bottom wall 4111. In this way, the blind hole 4111b can have sufficient depth, so that the conductive terminal 423 and the pin 4124 in the blind hole 4111b can fully abut, to ensure the reliability of the electrical connection. The outer edge of the region in which the first via hole 4111a and the blind hole 4111b are formed and the bottom surface of other parts of the bottom wall 4111, as well as part of the side wall 4112 of the atomization shell 411, can form a containing space that can accommodate some components in the power supply assembly 420, such as the bracket 425, the airflow sensor 424 or the chip mentioned below, and the like. In this way, the utilization rate of the internal space of the atomizer 400 can be improved.

[0028] In summary, by arranging the pin 4124 to extend out of the first via hole 4111a, bend and then extend into the blind hole 4111b, the assembly of the conductive terminal 423 and the pin 4124 can be facilitated, so that the assembly process of the conductive terminal 423 and the pin 4124 only needs to be completed by positioning and moving, thereby simplifying the assembly process of the atomizer 400. Therefore, the above processes can be easily realized by numerical control machines, reducing the processes that need to be operated manually, and being conducive to improving the level of automatic assembly of the atomizer 400, so that the manufacturing of the atomizer 400 can be cost-effective.

[0029] In combination Figures 5 to 7 In some embodiments, the atomization assembly 410 further comprises a liquid storage member 4116 arranged in the containing space 411a, the liquid storage member 4116 is provided with an atomization channel 4116a, and the atomization core 412 is arranged in the atomization channel 4116a. The atomization core 412 can receive part of the atomization substrate stored in the liquid storage member 4116 and atomize it into an aerosol. The bottom wall 4111 of the atomization shell 411 has an air inlet 4111c, the air inlet 4111c communicates with the atomization channel 4116a, and gas can enter the atomization channel 4116a from the air inlet 4111c and drive the aerosol to flow in the atomization channel 4116a, and finally flow out of the atomization assembly 410 for use by the user. Specifically, the liquid storage member 4116 is liquid storage cotton.

[0030] The atomization shell 411 further comprises an atomization shell upper cover 4113 detachably arranged, and the atomization shell upper cover 4113 and the side wall 4112 and the bottom wall 4111 of the atomization shell 411 enclose a containing space 411a. When the atomization shell upper cover 4113 is not installed, the liquid storage member 4116 and other components can be installed into the containing space 411a from one end of the atomization shell 411, and then after the atomization shell upper cover 4113 is installed, the bottom wall 4111 of the atomization shell 411 and the atomization shell upper cover 4113 can stably clamp the liquid storage member 4116 and other components in the containing space 411a. The atomization shell upper cover 4113 is provided with an air outlet in communication with the atomization channel 4116a, and the airflow in the atomization channel 4116a can flow out of the atomization assembly 410 through the air outlet. Optionally, the side of the atomization shell upper cover 4113 away from the bottom wall 4111 is further embedded with a liquid absorbing cotton 4115. Since the atomization of the atomization substrate may not be complete, and the aerosol may also produce condensate during flow, there may be liquid residue when the aerosol is discharged. The arrangement of the liquid absorbing cotton 4115 can absorb the liquid to reduce the residue of the liquid to improve the user experience.

[0031] In an embodiment, referring to Figure 4 and Figure 5 , the atomization core 412 comprises a heating member 4123, a liquid guiding member 4122 and an atomization tube 4121. The atomization tube 4121 is sleeved on the outer periphery of the liquid guiding member 4122, and the atomization tube 4121 is further provided with an opening, so that the liquid guiding member 4122 can be in contact with the liquid storage member 4116, and the atomization substrate can be transmitted from the liquid storage member 4116 to the liquid guiding member 4122. The liquid guiding member 4122 is sleeved on the outer periphery of the heating member 4123. The liquid guiding member 4122 can store a certain amount of atomization substrate, and guide part of the atomization substrate to the part of the liquid guiding member 4122 in contact with the heating member 4123. The heating member 4123 can heat the atomization substrate to atomize the atomization substrate into an aerosol. The heating member 4123 has the above-mentioned lead 4124, and the heating member 4123 is electrically connected to the conductive terminal 423 through the lead 4124. Among them, the atomization tube 4121 is in communication with the atomization channel 4116a and extends to the air inlet 4111c, and the lead 4124 is partially arranged in the atomization tube 4121.

[0032] In some embodiments, the above-mentioned first via hole 4111a can be the air inlet 4111c. In other embodiments, the first via hole 4111a is a via hole independent of the air inlet 4111c, and the lead 4124 passes out from the first via hole 4111a instead of the air inlet 4111c. In this way, the lead 4124 can be prevented from playing a role in guiding the condensate in the airflow channel 4116a, avoiding the condensate flowing along the lead 4124 to the battery assembly 420.

[0033] In some embodiments, the bottom wall 4111 is provided with a positioning tube 4114 at the air inlet 4111c extending towards the inside of the atomizing tube 4121, the hollow inside of the positioning tube 4114 is capable of allowing the airflow of the air inlet 4111c to pass through. The positioning tube 4114 extends into the atomizing tube 4121, so that the positioning tube 4114 is capable of limiting the movement of the atomizing tube 4121 in the radial direction, thereby further limiting the movement of the atomizing core 412. The liquid storage member 4116 is sleeved on the outer periphery of the atomizing core 412, and the positioning tube 4114 is further capable of limiting the movement of the liquid storage member 4116 through the atomizing core 412.

[0034] It can be understood that the pin 4124 can extend to the first via hole 4111a through various ways and then pass out from the first via hole 4111a. For example, the pin 4124 extends to the first via hole 4111a through the gap between the positioning tube 4114 and the atomizing tube 4121. For another example, the tube wall of the positioning tube 4114 is provided with a threading hole in communication with the first via hole 4111a, and the pin 4124 extends to the first via hole 4111a through the threading hole.

[0035] In some embodiments, the atomizing core 412 has two pins 4124, and the two pins 4124 can be connected to two conductive terminals 423 respectively, and the two conductive terminals 423 can be a positive conductive terminal 423 and a negative conductive terminal 423 respectively.

[0036] In some embodiments, the at least two pins 4124 are bent towards similar directions. In this way, the features of the bottom wall 4111 corresponding to the pins 4124 can be arranged close to each other. The distribution of the features related to the pins 4124 on the bottom wall 4111 can be more concentrated, so that the wiring of the pins 4124 can be more concentrated, thereby reducing the occupation of the internal space of the atomizer 400. Since the features of the blind hole 4111b require a thicker bottom wall 4111, the concentrated distribution of the blind hole 4111b can also reduce the thickness of the part of the bottom wall 4111 that is thicker, thereby facilitating the improvement of the space utilization and the reduction of the weight of the atomizer 400.

[0037] In an embodiment, the bottom wall 4111 is provided with two first via holes 4111a for the pins 4124 to pass through, and the two first via holes 4111a are arranged close to each other. In other words, the two first via holes 4111a are the features related to the pins 4124 described above.

[0038] Further, the included angle between the center lines of the two first via holes 4111a and the center of the air inlet 4111c (see FIG. 13) is less than 90 degrees. Figure 7The angle between the center of the two first through holes 4111a and the center of the air inlet 4111c is less than 90 degrees. In some embodiments, the angle between the center of the two first through holes 4111a and the center of the air inlet 4111c is less than 120 degrees. In other words, the two first through holes 4111a are arranged close to each other on the bottom wall 4111. In this way, the distribution of the first through holes 4111a on the bottom wall 4111 can be more concentrated, so that the wiring of the pin 4124 can be more concentrated, reducing the occupation of the internal space of the atomizer 400. Furthermore, the features such as the blind hole 4111b matched with the first through hole 4111a can also be more concentrated. Since the feature of the blind hole 4111b requires a thicker bottom wall 4111, the concentrated distribution of the blind hole 4111b can also reduce the thickness of the thicker part of the bottom wall 4111, which is beneficial to improve the space utilization and reduce the weight of the atomizer 400. Alternatively, the angle between the center of the two first through holes 4111a and the center of the air inlet 4111c is less than 90 degrees.

[0039] In some embodiments, in combination with Figure 5 The atomization tube 4121 is provided with a fastener 414, and the pin 4124 is located between the fastener 414 and the inner wall of the atomization tube 4121, and the fastener 414 presses the pin 4124 against the inner wall of the atomization tube 4121. In this way, when the atomization core 412 is not assembled with the atomization shell 411, the pin 4124 can be pressed against the inner wall of the atomization tube 4121 by the fastener 414 in the atomization tube 4121, so that the pin 4124 can have higher stability when the atomization core 412 is not assembled with the atomization shell 411, and is not easy to shake, thereby facilitating the assembly of the atomization core 412 and the atomization shell 411, that is, facilitating the extension of the pin 4124 into the first through hole 4111a and the extension of the positioning tube 4114 into the atomization tube 4121.

[0040] In the related art, the pin 4124 of the atomization core 412 in the atomizer 400 extends through the bottom wall 4111 of the atomization shell 411 to be connected with the conductive terminal 423. The extension of the pin 4124 through the bottom wall 4111 causes the bottom wall 4111 to form a through hole, and the gap between the through hole and the pin 4124 can cause the atomization assembly 410 to leak liquid or gas. In the related art, during the production process of the atomizer 400, the through hole on the bottom wall 4111 is sealed by using a glue dispensing method. However, the glue dispensing process requires process equipment or jigs that are different from the assembly process, and the semi-finished product needs to be switched to different equipment for processing, so the sealing method by using the glue dispensing process can cause the production process of the atomizer 400 to be more complex, which is not conducive to improving the assembly efficiency and the assembly automation level. In order to solve the above technical problems, the present application can provide the following embodiments.

[0041] In some embodiments, in combination with Figures 6 to 8The bottom wall 4111 of the atomization shell 411 is provided with a containing groove 4111d in communication with the containing space 411a, the first through hole 4111a is arranged at the bottom of the containing groove 4111d, the containing groove 4111d is provided with a sealing element 413, the sealing element 413 is provided with a second through hole 4131 in communication with the first through hole 4111a, the pin 4124 is bent to extend into the blind hole 4111b after passing through the second through hole 4131 and the first through hole 4111a, and the sealing element 413 is used to seal the peripheral side of the pin 4124. In this way, when the pin 4124 passes through the second through hole 4131, the sealing element 413 can seal the peripheral side of the pin 4124, thereby preventing the atomization substrate from flowing through the second through hole 4131. Further, the gap between the peripheral side of the sealing element 413 and the side wall 4112 of the containing groove 4111d can also be sealed by the interference fit between the sealing element 413 and the containing groove 4111d, thereby preventing the atomization substrate from leaking through the first through hole 4111a. In the above manner, the sealing of the first through hole 4111a can be realized by the sealing element 413. The sealing element 413 can be made by other processes first, and the sealing element 413 can be assembled like other components during assembly of the atomizer 400, only by positioning and moving of the assembly equipment, so that the atomizer 400 no longer needs a glue dispensing process to realize the sealing of the first through hole 4111a during assembly, thereby simplifying the assembly process of the atomizer 400 and facilitating the improvement of the assembly efficiency and the assembly automation level of the atomizer 400.

[0042] Optionally, on the basis of the above embodiment, the angle between the center lines of the two first through holes 4111a and the center of the air inlet 4111c is less than 120 degrees, and more preferably less than 90 degrees. In this way, the sealing element 413 can cover the two first through holes 4111a close to each other with a smaller volume, which is conducive to reducing the manufacturing cost of the atomizer 400.

[0043] The sealing of the peripheral side of the pin 4124 by the sealing element 413 can be realized in various ways, and exemplary descriptions of the embodiments of the sealing of the peripheral side of the pin 4124 by the sealing element 413 are as follows.

[0044] In some embodiments, in combination with Figure 8An elastic membrane layer integrally formed with the seal 413 is formed in the middle of the second through hole 4131. The pin 4124 pierces through the elastic membrane layer to pass through the second through hole 4131. Specifically, when the seal 413 is formed, an elastic membrane layer is formed inside the second through hole 4131, but at this time, no perforation is provided on the elastic membrane layer. During the assembly of the atomizer 400, when the pin 4124 extends into the second through hole 4131, it can pierce the elastic membrane layer and pass through it. It should be noted that the process of the pin 4124 piercing the elastic membrane layer can be described by the following example: When the pin 4124 contacts the elastic membrane layer but has not yet pierced it, the pin 4124 will push the elastic membrane layer to produce elastic deformation. As the pin 4124 continues to gradually push, a gap will appear in the elastic membrane layer, the size of which is smaller than the diameter of the pin 4124. After the notch is created, the elastic membrane layer around the notch will undergo elastic deformation under the pressure of the pin 4124, thus allowing the diameter of the notch to be large enough for the pin 4124 to pass through. Therefore, the elastic membrane layer around the notch is pressed tightly against the periphery of the pin 4124. So after the pin 4124 punctures the elastic membrane layer and passes through, the elastic membrane layer is able to seal the periphery of the pin 4124.

[0045] In other embodiments, an elastomer or elastic film may be inserted into the first through hole 4111a, and the pin 4124 may be sealed around the pin by piercing the elastomer or elastic film.

[0046] In some embodiments, the diameter of the second via 4131 is smaller than the diameter of the pin 4124. Thus, after the pin 4124 extends into the second via 4131, the pin 4124 and the second via 4131 can achieve a sealing effect through an interference fit.

[0047] In some embodiments, the seal 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 circumference of the sealing member 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 4112 of the sealing member 413 are in an interference fit with the side wall 4112 of the receiving groove 4111d. This arrangement facilitates the assembly of the sealing member 413 into the receiving groove 4111d.

[0048] In some embodiments, the power supply assembly 420 is arranged in the housing 430 and is arranged above and below the atomization assembly 410 along the axis of the housing 430. In this way, the shape of the atomizer 400 can be matched to the habits of the user, thereby enhancing the user experience,

[0049] In some embodiments, in combination Figure 2 and Figure 3 , the power supply assembly 420 includes a control assembly 422 and a battery 421 electrically connected to the control assembly 422.

[0050] The control assembly 422 further includes an airflow sensor 424 and a conductive terminal 423. The control assembly 422 is arranged between the battery 421 and the atomization assembly 410, and the airflow sensor 424 and the conductive terminal 423 are both directly welded on the control assembly 422, thereby reducing the components that need to be wired in the atomizer 400 and facilitating the improvement of assembly efficiency. Optionally, the side of the battery 421 close to the control assembly 422 is provided with a positive electrode and a negative electrode of the battery 421, so that the positive electrode and the negative electrode of the battery 421 can be directly connected to the control assembly 422 located on one side of the battery 421, and further reducing the components that need to be wired in the atomizer 400.

[0051] In some embodiments, the airflow sensor 424 is arranged on the side of the control assembly 422 facing the atomization assembly 410. The control assembly 422 is further provided with a first air passage, and the airflow can flow through the first air passage and pass through the airflow sensor 424, so that the airflow sensor 424 can control the opening or closing of the atomization core 412 by detecting the flow of the airflow. After the airflow passes through the airflow sensor 424, it can enter the atomization channel 4116a from the air inlet hole.

[0052] In some embodiments, the control assembly 422 and the atomization assembly 410 are further provided with a bracket 425, and the bracket 425 is provided with a via for the conductive terminal 423 to pass through, so that the conductive terminal 423 can pass through the conductive terminal 423 and extend into the blind hole 4111b. The bracket 425 is further provided with a space for accommodating the airflow sensor 424. The provision of the space improves the utilization of space in the atomizer 400. The bracket 425 is further provided with a second air passage, and the airflow can directly flow through the second air passage and enter the atomization channel 4116a. The provision of the bracket 425 can prevent the condensate or the atomization substrate from directly dropping onto the control assembly 422, thereby avoiding short circuit.

[0053] In some embodiments, the side of the control assembly 422 facing the battery 421 is provided with an indicator light 4222. When the user inhales, the indicator light 4222 can light up to prompt the user about the working state of the atomizer 400. The indicator light 4222 can emit light to the outside through an opening provided on the housing 430, so as to be observed by the user.

[0054] In some embodiments, the atomizer 400 further comprises a light guide seat 450, in other words, the seat 450 described above is a light guide seat 450 supported by a light guide material, which is installed on the shell 430 near one end of the power supply assembly 420. The light emitted by the indicator light 4222 can irradiate the light guide seat 450, so that the user can observe the light guide seat 450 to obtain a prompt. Further, a light guide piece 426 is further arranged between the battery 421 and the shell 430, so as to guide the light of the indicator light 4222 to the light guide seat 450.

[0055] In some embodiments, the atomizer 400 further comprises a suction piece 440, which is installed on the shell 430 near one end of the atomization assembly 410. The suction piece 440 has an air outlet channel 441, which communicates with the air outlet of the atomization shell upper cover 4113 to communicate with the atomization channel 4116a. The aerosol in the atomization channel 4116a can be discharged through the air outlet channel 441 for the user to use. Optionally, the sealing piece 413 near one end of the suction piece 440 is embedded with liquid absorbing cotton 4115 towards one side of the suction piece 440. Since the atomization of the atomization substrate may not be complete, and the aerosol may also produce condensate during flow, there may be liquid residue when the aerosol is discharged from the air outlet. The arrangement of the liquid absorbing cotton 4115 can absorb the liquid to reduce the residue of the liquid in the air outlet channel 441 to improve the user experience.

[0056] The above is only an embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structure or equivalent process transformation using the content of the specification and drawings of the present application, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
