Description

Technical Field

[0001] This application relates to the technical field of atomization, and more specifically, to an electronic atomization device. Background Art

[0002] An electronic atomization device includes an atomization mechanism and a power supply mechanism. The power supply mechanism is used to provide the power required for the operation of the atomization mechanism and can control and adjust the working state of the atomization mechanism. The power supply mechanism generally includes a battery and a control board. In the existing solution, two electrode posts are provided on the control board, and the electrode posts are electrically connected to the pins of the atomization mechanism to realize the electrical conduction of the device circuit. Therefore, when manufacturing the electronic device, two electrode posts need to be welded on the control board. Due to the volume limitation of the control board, the difficulty of welding the electrode posts is relatively high, which increases the material cost and labor cost of the electronic atomization device. And in order to facilitate the stability of the circuit connection after assembly, the perpendicularity requirement for the electrode posts during welding is relatively high, and the length of the electrode posts is limited. If the length is too large, it is very easy to cause inclination during assembly or use, resulting in poor line contact and affecting the operation of the electronic atomization device.

[0024] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0025] The present application provides an electronic atomization device (hereinafter referred to as the atomization device), which can be used to heat an atomization matrix A to generate an aerosol that can be used.

[0026] It should be noted that the aerosol mentioned in the terms refers to a dispersion of solid particles or liquid particles in a gas. As used herein, "aerosol" generally refers to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0027] Please refer to Figures 1 to 6 , the atomizing device includes a housing assembly 100, an atomizing core assembly 200, a first seal 300, and a main control assembly. The housing assembly 100 has an accommodation space 110 therein. The housing assembly 100 can be understood as a collection of related components that constitute the overall outer contour structure of the atomizing device. For example, the housing assembly 100 can be assembled by combining one or more components, and corresponding assembly structures are provided inside or on the wall of the housing assembly 100 to assemble other components of the atomizing device to the housing assembly 100; with the outer housing 140, users can carry, move, operate, and use the atomizing device.

[0028] The atomizing core assembly 200 is used to heat and atomize the atomizing matrix 700 to form an aerosol. The atomizing core assembly 200 is disposed in the accommodation space 110. The atomizing core assembly 200 includes a heating core 210, a first pin 220, and a second pin 230. The first pin 220 and the second pin 230 are used to realize the electrical connection between the heating core 210 and the main control assembly.

[0029] A liquid storage chamber 120 is further provided in the housing assembly 100. An atomizing chamber 130 is formed in the middle of the liquid storage chamber 120. The atomizing core assembly 200 is disposed in the atomizing chamber 130. The liquid storage chamber 120 is provided with an atomizing matrix 700. The atomizing core assembly 200 further includes a liquid guiding member 240. The atomizing matrix 700 is introduced into the liquid guiding member 240 through a liquid guiding channel (not shown in the figure) provided by the liquid storage chamber 120 and the atomizing core assembly 200, and then the atomizing matrix 700 on the liquid guiding member 240 is heated by the heating core 210 to form an aerosol.

[0030] The main control component includes a battery 600 and a control circuit board 400, which are electrically connected to the control circuit board 400. The control circuit board 400 is also electrically connected to the first pin 220 and the second pin 230, and can supply power to the heating core 210 and control the working state of the heating core 210, such as switching the working curve (heating temperature) of the heating core 210. The main control component also includes a switch button (not shown in the figure), which is exposed on the wall of the shell component 100. The battery 600 and the control circuit board 400 are arranged in the accommodating space 110. The control circuit board 400 is provided with a first conductive area 410 and a second conductive area 420 on the side facing the first seal 300. The first conductive area 410 and the second conductive area 420 are formed by electroplating or brushing a conductive material on the control circuit board 400. The conductive material includes a metal material with excellent conductive properties such as nickel or gold.

[0031] The first sealing member 300 is disposed in the accommodating space 110 and between the control circuit board 400 and the atomizer core assembly 200; the first sealing member 300 has a first surface 310 and a second surface 320, the first surface 310 is disposed toward the atomizer core assembly 200, and the second surface 320 is disposed toward the control circuit board 400; the first sealing member 300 is provided with a lead hole 330, and the lead hole 330 is disposed through the first sealing member 300 in a direction from the first surface 310 to the second surface 320, One end of the first pin 220 and the second pin 230 are connected to the heating core 210, and the other end passes through the lead hole 330 from the first surface 310, and passes through the lead hole 330 to the second surface 320, and is bent on the second surface 320 to fit with the second surface 320. Since the control circuit board 400 is arranged to fit with the second surface 320, the first pin 220 and the first conductive area 410 are contacted and connected one by one, and the second pin 230 and the second conductive area 420 are contacted and connected one by one. Preferably, the bending angle of the first pin 220 and the second pin 230 is 90°.

[0032] Furthermore, the lead hole 330 and the heating core 210 are coaxially arranged, so that the first pin 220 and the second pin 230 can pass vertically through the lead hole 330 during assembly.

[0033] Since the control circuit board 400 is disposed on the second surface 320 of the first seal 300 and is in close fit with the first seal 300, through the combined cooperation of the control circuit board 400 and the first seal 300, the first pin 220 and the second pin 230 can be bent to be in contact connection with the first conductive region 410 and the second conductive region 420 respectively, and the first pin 220 is in close fit with the first conductive region 410, and the second pin 230 is in close fit with the second conductive region 420. This can not only achieve circuit conduction but also effectively ensure good line contact, meeting the working requirements of the atomization device. At the same time, since the control circuit board 400 is in contact connection with the first pin 220 and the second pin 230, there is no need to provide electrode posts on the control circuit board 400 that are no higher than 8 mm and have high perpendicularity requirements, which simplifies the processing procedure of the entire atomization device, saves production costs and material costs, and due to the contact connection, reduces the assembly difficulty and improves the assembly efficiency and quality.

[0034] In order to further achieve a tight fit between the first seal 300 and the control circuit board 400, so that the first pin 220 and the second pin 230 can be in tight and stable contact connection with the control circuit board 400, a first limiting member 340 is provided on the second surface 320 of the first seal 300, and the first limiting member 340 and the lead hole 330 are arranged separately from each other; a second limiting member 430 is provided on the control circuit board 400, and the first limiting member 340 and the second limiting member 430 cooperate to fix the control circuit board 400 and the first seal 300, so that the first pin 220 is in close fit with the first conductive region 410 and the second pin 230 is in close fit with the second conductive region 420.

[0035] Further, one of the first limiting member 340 and the second limiting member 430 is a limiting post, and the other is a limiting hole. The limiting post is inserted into the limiting hole to fix the control circuit board 400 and the first seal 300.

[0036] Please refer to Figure 5 and Figure 6 , a limiting post (first limiting member 340) is provided on the second surface 320 of the first seal 300, and a limiting hole (second limiting member 430) is provided on the control circuit board 400. The limiting post (first limiting member 340) is inserted into the limiting hole (second limiting member 430) to fix the control circuit board 400 and the first seal 300, so that the control circuit board 400 is in close contact with the second surface 320.

[0037] In one embodiment, to prevent the first seal 300 and the control circuit board 400 from moving axially along the positioning posts after assembly, the positioning posts include a base portion 341 and a limiting portion 342. The base portion 341 and the limiting portion 342 are arranged in sequence along the circumferential direction of the positioning post. The size of the limiting portion 342 is larger than the size of the limiting hole. The limiting portion 342 passes through the limiting hole and abuts against the side of the control circuit board 400 facing away from the second surface 320, so that the limiting portion 342 can fix the control circuit board 400.

[0038] Furthermore, the size of the base portion 341 is matched with the size of the limiting hole. Specifically, the base portion 341 and the limiting hole are in an interference fit, which can prevent the first seal 300 and the control circuit board 400 from moving radially or rotating circumferentially along the positioning post after installation.

[0039] In one embodiment, the limiting portion 342 is made of an elastic material, so that the limiting portion 342 can elastically deform and pass through the limiting hole, and abut against the side of the control circuit board 400 facing away from the second surface 320 under the action of the elastic restoring force. The limiting portion 342 and the base portion 341 are an integrally formed structure. During assembly, the limiting portion 342 elastically deforms and passes through the limiting hole, and then abuts against the control circuit board 400 after the deformation is restored. At the same time, the base portion 341 is arranged in the limiting hole to realize the fixation between the first seal 300 and the control circuit board 400. This structure reduces the number of parts and the assembly process, simplifies the assembly, and can improve the assembly efficiency. The limiting portion 342 can prevent the control circuit board 400 from moving axially along the positioning post, thereby pressing the control circuit board 400 against the second surface 320 of the first seal 300, and can press the first pin 220 and the second pin 230 to ensure good line contact and improve the working stability of the atomization device.

[0040] In another embodiment, the base portion 341 and the limiting portion 342 can also be a split structure. The base portion 341 can be inserted into the limiting hole, and then the limiting portion 342 is connected to the base portion 341. The limiting portion 342 abuts against the side of the control circuit board 400 facing away from the first seal 300 to realize the limiting and fixation between the two.

[0041] Please refer to Figure 5 , to prevent the first pin 220 and the second pin 230 from moving due to the shaking of the atomization device during assembly or use after being bent, resulting in poor line contact, a first limiting groove 350 is provided on the second surface 320. The first pin 220 and the second pin 230 can pass through the lead hole 330 and are bent and arranged in the first limiting groove 350.

[0042] Please refer to Figure 6, a second limiting groove 440 is provided on the control circuit board 400. The first conductive region 410 and the second conductive region 420 are disposed in the second limiting groove 440 in an insulated manner. The first limiting groove 350 and the second limiting groove 440 cooperate to fix the first pin 220 and the second pin 230. Specifically, the first limiting groove 350 and the second limiting groove 440 cooperate to form a cavity, and the cavity matches the outer shapes of the first pin 220 and the second pin 230. For example, when the outer shapes of the first pin 220 and the second pin 230 are cylindrical structures, the cavity is a cylindrical structure, and the first limiting groove 350 and the second limiting groove 440 are cylindrical structures.

[0043] In one embodiment, there are two first limiting grooves 350 and two second limiting grooves 440; the first limiting grooves 350 and the second limiting grooves 440 cooperate in a one-to-one correspondence to fix the first pin 220 and the second pin 230.

[0044] Since the first pin 220 is in contact connection with the first conductive region 410, and the second pin 230 is in contact connection with the second conductive region 420, and at least part of the conductive structures of the first pin 220 and the second pin 230 are exposed, and contact between the two is likely to cause a short circuit. Therefore, the first pin 220 and the second pin 230 are disposed in an insulated manner. Specifically, the first seal 300 is made of a silicone material and has insulating ability. By separating the two first limiting grooves 350, the insulated setting of the first pin 220 and the second pin 230 can also be achieved. The base body of the control circuit board 400 is generally also made of an insulating material. The second limiting groove 440 provided separately can also achieve the insulated setting of the first conductive region 410 and the second conductive region 420, and at the same time can further ensure the insulated setting of the first pin 220 and the second pin 230.

[0045] In one embodiment, the first pin 220 and the second pin 230 are also provided in a one-to-one correspondence with the first limiting groove 350 and the second limiting groove 440. Specifically, each first pin 220 is correspondingly provided with a first limiting groove 350 and a second limiting groove 440.

[0046] In one embodiment, the atomization core assembly 200 includes a plurality of heating cores 210, a plurality of first pins 220, and a plurality of second pins 230. The plurality of first pins 220 pass through the lead holes 330, are bent to the second surface 320, and are in contact connection with the first conductive region 410. A plurality of first conductive regions 410 and a plurality of second conductive regions 420 are provided in isolation from each other. The plurality of second pins 230 pass through the lead holes 330, are bent to the second surface 320, and are in one-to-one contact connection with the second conductive regions 420. The arrangement of the first conductive regions 410 and the second conductive regions 420 also facilitates the one-to-one contact connection of the plurality of first pins 220 and the second pins 230. By providing the plurality of heating cores 210, the plurality of first pins 220, and the plurality of second pins 230, the number of working heating cores 210 can be operationally controlled to change the working power of the atomization core assembly 200 and achieve the adjustment of different heating curves (temperatures).

[0047] It can be understood that when each heating core 210 is provided with a first pin 220 and a second pin 230 respectively, the first pin 220 and the second pin 230 are respectively connected to the electrode posts in one-to-one correspondence. At this time, a plurality of electrode posts need to be provided on the control circuit board 400, which not only increases the welding workload, but also increases the production cost, increases the occupied volume of the control circuit board 400, and increases the assembly difficulty. Through the arrangement of the first conductive region 410 and the second conductive region 420, the production process is saved, the occupied volume is saved, the assembly difficulty is simplified, and the production cost can be further reduced.

[0048] In another embodiment, the atomization core assembly 200 includes a plurality of heating cores 210. The plurality of heating cores 210 share a first pin 220 and / or a second pin 230, or some of the heating cores 210 share a first pin 220 and / or a second pin 230. Through the arrangement of the first conductive region 410 and the second conductive region 420, the process can be saved and the assembly difficulty can be reduced.

[0049] In one embodiment, the electronic atomization device further includes a second seal 500. The second seal 500 is disposed in the accommodation space 110 and on the side of the control circuit board 400 facing away from the second surface 320. The second seal 500 is closely attached to the control circuit board 400. Through the arrangement of the second seal 500, the components in the accommodation space 110 can be further made more compact, the control circuit board 400 and the first seal 300 can be more closely attached, and at the same time, the arrangements of the first seal 300 and the second seal 500 can also prevent the atomization matrix 700 from leaking and protect the entire atomization device.

[0050] In one embodiment, the housing assembly 100 further includes an outer housing 140 and a base 150. The base 150 and the outer housing 140 form the accommodation space 110.

[0051] It should be further explained that, in order to better describe the layout position relationship of each component in the atomization device, the shell assembly 100 is defined as having a relatively arranged proximal end 160 and a distal end 170, and the accommodating space 110 is formed between the proximal end 160 and the distal end 170. The proximal end 160 refers to the end relatively close to the user when the user uses it, and the distal end 170 is the end relatively far away from the user. The electronic atomization device also includes a suction nozzle 180, and the user uses the suction nozzle 180 to achieve the suction action. Therefore, one end where the suction nozzle 180 is set is also the proximal end 160, and the end opposite to the suction nozzle 180 is the distal end 170. The second seal 500, the control circuit board 400, the first seal 300, and the atomization core are arranged in sequence and compactly along the direction from the distal end 170 to the proximal end 160, which can reasonably utilize the accommodating space 110 and also make the various components in close contact.

[0052] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For technicians in the technical field to which the present application belongs, they can also make some simple deductions, deformations or substitutions based on the ideas of the present application.
