Description
Technical Field
[0001] The present application relates to the field of electronic atomization technology, and in particular to an atomization core assembly and an electronic atomization device. Background Art
[0002] Electronic atomizers, also known as e-cigarettes, heat and vaporize an atomizing medium to create an aerosol for the user to inhale, simulating the sensation of smoking. As a popular alternative to cigarettes, they are a popular choice among smokers. Traditional electronic atomizers consist of an atomizer unit and a power supply unit. The atomizer unit contains an oil reservoir and an atomizing chamber. The atomizing medium is stored in the oil reservoir, which houses an atomizing core. The power supply unit supplies power to the core, heating the atomizing medium in the oil reservoir and vaporizing it to create an aerosol for the user to inhale.
[0003] However, in the process of atomization, the aerosol generated in the atomization chamber of the existing electronic atomization devices on the market will adhere to the heating wire pins of the atomization core. After the atomization stops, the aerosol will cool and generate condensation, causing the condensation to adhere to the pins and flow down along the pins. If the seal between the pins and the sealing silicone is poor, the condensation will leak from the holes between the pins and the sealing silicone to the side of the circuit board, causing the electronic atomization device to malfunction and pose a great safety hazard. Therefore, before the pins are soldered to the circuit board, it is necessary to consider the sealing between the sealing silicone and the pins. The current common sealing method is to achieve the purpose of sealing by dispensing glue in the gap between the pins and the holes of the sealing silicone. However, the use of dispensing glue will result in dispensing deviations during the dispensing process, resulting in reduced production efficiency and increased production costs.

[0042] An embodiment of the present application provides an electronic atomization device, which is used to heat an atomization medium stored inside the device to form an aerosol for inhalation by a user.
[0043] The following describes the structure of the electronic atomization device in this application, taking an electronic cigarette as an example. This embodiment is merely an example and does not limit the technical scope of this application. It is understood that in other embodiments, the electronic atomization device of this application is not limited to an electronic cigarette, but can also be any other electronic atomization device that can atomize an atomizing medium into an aerosol, without limitation here.
[0044] See Figures 1 to 5 , Figure 1 An exploded schematic diagram of a partial structure of the electronic atomization device 10 in one embodiment of the present application is shown. Figure 2 The figure shows the appearance of part of the structure of the electronic atomization device 10 in one embodiment of the present application. Figure 3 A top view of a partial structure of the electronic atomization device 10 is shown. Figure 4 and Figure 5 A cross-sectional view of a partial structure of an electronic atomization device 10 is shown. An embodiment of the present application provides an electronic atomization device 10, comprising a housing 100 and an atomization unit 200, wherein the atomization unit 200 is disposed within the housing 100 and, together with the inner wall of the housing 100, forms an oil storage chamber 101 for accommodating an atomization medium. The atomization unit 200 comprises a sealing seat 210 and an atomization core assembly 220, the sealing seat 210 and the atomization core 221 being interconnected and forming the atomization chamber 201 together. The atomization core assembly 220 comprises an atomization core 221, which is disposed within the atomization chamber 201 and is used to heat and atomize the atomization medium flowing from the oil storage chamber 101 into the atomization unit 200 to generate an aerosol for inhalation by the user.
[0045] In one embodiment, one end of the housing 100 has a nozzle (not shown in the figure), the nozzle has an air outlet, and Figure 4As shown, the shell wall of the housing 100 is provided with an atomizing air passage 102 connected to the air outlet. The atomizing air passage 102 runs through the housing 100 and is connected to the air outlet. The oil storage chamber 101 is connected to the atomizing air passage 102 via the atomizing chamber 201. When the user inhales, the atomizing medium flows into the atomizing core 221, which heats the atomizing medium to generate an aerosol. The aerosol gathers in the atomizing chamber 201, mixes with the air entering the housing 100 from the outside, and is then discharged from the air outlet along the atomizing air passage 102 to the outside of the electronic atomizing device 10, and then inhaled into the mouth of the user.
[0046] Furthermore, the electronic atomization device 10 further includes an airflow sensor (not shown in the figure), such as Figure 5 As shown, the atomizer core assembly 220 is provided with a mounting position 211 connected to the outside world. The airflow sensor is set in the mounting position 211. When the user uses the electronic atomizer device 10 to inhale, the airflow sensor is used to sense the negative pressure generated by the airflow and trigger the atomizer core assembly 220 to work, so that the atomizer core 221 can heat the atomized medium flowing into itself. Therefore, in order to achieve this purpose, the airflow sensor is able to sense the negative pressure generated by the air flow, combined with Figure 4 and Figure 5 As shown, the shell wall of the housing 100 also defines an airflow sensing channel 103, which is isolated from the atomizing airway 102. One end of the airflow sensing channel 103 is connected to the air outlet, and the other end is connected to the mounting position 211. When the user inhales, the outside air can flow through the mounting position 211 and the airflow sensing channel 103 under the action of suction, forming an airflow. The airflow sensor senses the negative pressure generated by the airflow, thereby triggering the atomizing core 221 to heat the atomizing medium, realizing the function of automatic heating when inhalation and stopping heating when inhalation stops.
[0047] In this way, by opening the atomizing airway 102 and the airflow sensing channel 103 in the shell wall of the shell 100, on the one hand, the internal structure of the electronic atomizer is simplified, and there is no need to set a center tube in the oil storage chamber 101, which facilitates the production and assembly of the electronic atomizer, avoids the problem of assembly errors, saves the material of the center tube, and greatly reduces the production and manufacturing cost of the electronic atomizer; on the other hand, hiding the airway in the shell wall of the shell 100 can highlight the novelty and differentiation of the electronic atomizer product, avoid the problem of product homogeneity, and improve the market competitiveness of the product.
[0048] See Figure 1 、 Figure 6 and Figure 7In terms of the structure of the atomizer core assembly 220, in addition to the atomizer core 221, the atomizer core assembly 220 also includes a support base 222, a seal 223, and a circuit board 224. The support base 222 and the seal base 210 are interconnected and together form the atomization chamber 201. The mounting position 211 is provided within the support base 222. The seal 223 is attached to one side of the support base 222, and the circuit board 224 is attached to the side of the seal 223 facing away from the support base 222, so that the seal 223 is sandwiched between the support base 222 and the circuit board 224, thereby being able to be fixed. The circuit board 224 is used to electrically connect to a battery or an external power source to control the logic on and off of the circuit, thereby controlling the battery or external power source to power the atomizer core 221. The atomizer core 221 is disposed on one side of the support base 222 , and has a heating wire. The heating wire has a pin 2211 . The pin 2211 passes through the support base 222 and the seal 223 and is connected to the circuit board 224 , so that the atomizer core 221 can be electrically connected to the circuit board 224 .
[0049] Specifically, if Figure 8 As shown, the support base 222 is provided with a through hole 2221 passing through the opposite sides of itself, the sealing member 223 is provided with a socket 2231 passing through the opposite sides of itself, and the circuit board 224 is provided with a via hole 2241 passing through the opposite sides of itself. The through hole 2221, the socket 2231 and the via hole 2241 are connected to each other, and the pin 2211 passes through the through hole 2221, the socket 2231 and the via hole 2241, and is optionally connected to the hole wall of the via hole 2241 by welding, thereby realizing the connection between the pin 2211 and the circuit board 224.
[0050] Furthermore, as described in the background art, during the atomization process of the electronic atomization device 10, the aerosol generated in the atomization chamber 201 will adhere to the pin 2211 of the heating wire. After the atomization stops, the aerosol will cool to generate condensate, causing the condensate to adhere to the pin 2211 and flow downward along the pin 2211. If the seal between the pin 2211 and the seal 223 is poor, the condensate will leak from the hole gap between the pin 2211 and the seal 223 to the side of the circuit board 224, thereby causing the electronic atomization device 10 to not work properly and pose a great safety hazard. Therefore, before the pin 2211 is welded to the circuit board 224, it is necessary to consider the sealing between the sealing silicone and the pin 2211. The existing common sealing method is to achieve the purpose of sealing by dispensing glue in the gap between the pin 2211 and the hole of the sealing silicone. However, the use of the dispensing glue sealing method will result in dispensing deviations during the dispensing process, resulting in a decrease in production efficiency and an increase in production costs.
[0051] Therefore, in order to solve this problem, the applicant of this application thought of the idea after research that the pin 2211 and the hole wall of the socket 2231 can be made to pass through the pin 2211 by means of an interference fit, so that there is no gap between the pin 2211 and the hole wall of the socket 2231, so that the condensate will not leak out of the socket 2231 along the pin 2211, and the condensate is prevented from leaking to the side of the sealing silicone where the circuit board 224 is provided, thereby avoiding safety hazards and ensuring the normal use of the electronic atomization device 10; and by adopting a sealing method of making the pin 2211 and the hole wall of the socket 2231 perform an interference fit, there is no need to dispense glue on the pin 2211 to achieve the purpose of forming a seal between the pin 2211 and the hole wall of the socket 2231, thereby improving the production efficiency of the electronic atomization device 10 and reducing production costs.
[0052] In a specific implementation, the seal 223 is provided with a blind hole 2232, i.e., a hole that is open at one end and closed at the other end. The socket 2231 is formed on the bottom wall of the blind hole 2232, specifically formed by the pin 2211 piercing the bottom wall of the blind hole 2232. In this way, the aperture of the socket 2231 can be adapted to that of the pin 2211, thereby achieving the purpose of making the pin 2211 fit tightly against the hole wall of the socket 2231. Preferably, the material of the seal 223 is an elastic material, such as a silicone material. In this way, under the action of an external force (for example, the contact force between the pin 2211 and the wall of the hole 2231 after the pin 2211 pierces the seal 223), the seal 223 can undergo a recoverable deformation, so that the pin 2211 and the wall of the hole 2231 can fit more closely and ensure that there is no gap between the pin 2211 and the wall of the hole 2231, thereby achieving the purpose of making the seal 223 and the pin 2211 more tightly sealed.
[0053] It is worth noting that although the seal 223 is sandwiched between the support base 222 and the circuit board 224, the seal 223 is still capable of moving relative to the support base 222 and the circuit board 224. Therefore, in order to better secure the seal 223, the seal 223 has a connecting post 2233 on the side facing the support base 222. A blind hole 2232 is formed in the connecting post 2233, and the connecting post 2233 passes through the through hole 2221 of the support base 222. Preferably, the outer diameter of the connecting post 2233 is equal to the aperture of the through hole 2221, so that the connecting post 2233 will not be displaced under the limiting action of the through hole 2221, thereby ensuring that the seal 223 will not move relative to the support base 222 and the circuit board 224.
[0054] Furthermore, in order to fix the circuit board 224 in the housing 100 and prevent the circuit board 224 from moving at will, as shown in FIG. Figure 9As shown, in a preferred embodiment, the support base 222 has an enclosing portion 2222 on the edge of one side away from the atomizer core 221. The enclosing portion 2222 is annular and encloses a mounting groove 2223. The sealing member 223 is attached to the bottom wall of the mounting groove 2223. The circuit board 224 is accommodated in the mounting groove 2223 and connected to the side wall of the mounting groove 2223, so that the circuit board 224 and the support base 222 can be fixedly connected to each other to prevent the circuit board 224 from moving at will.
[0055] In an alternative embodiment, please refer to Figure 9 The sidewalls of the mounting groove 2223 are provided with a plurality of fixing blocks 2224, and the edges of the circuit board 224 overlap the fixing blocks 2224. Of course, it is understandable that in other embodiments, the circuit board 224 can also be adhered to the sealing member 223 by gluing, or the sidewalls of the circuit board 224 can be glued to the sidewalls of the mounting groove 2223, which is not limited here.
[0056] It is also worth noting that, since the size of the sealing member 223 may not be guaranteed to be consistent with the size of the bottom wall of the mounting groove 2223, the side wall of the sealing member 223 may not be able to fit the side wall of the mounting groove 2223, that is, there will be a gap between the side wall of the sealing member 223 and the side wall of the mounting groove 2223. In order to ensure that the sealing member 223 will not bend or produce relative displacement with the support seat 222 at any time, as shown in FIG. Figure 10 As shown, a plurality of positioning blocks 2225 are provided in the gap formed between the side wall of the seal 223 and the side wall of the mounting groove 2223. One end of the positioning block 2225 abuts against the side wall, and the other end abuts against the side wall of the seal 223, so as to achieve the purpose of completely fixing the seal 223.
[0057] In a preferred embodiment, see Figure 1 and Figure 11 The atomizer core assembly 220 further includes an oil absorption member 225 , which is used to absorb condensation formed when the aerosol in the atomizer chamber 201 is cooled, thereby preventing the condensation from being deposited in the atomizer chamber 201 and further preventing the condensation from leaking onto the circuit board 224 .
[0058] In addition, as a further improvement, the support seat 222 and the sealing member 223 are respectively provided with an oil through hole 2226 and an oil guide hole 2234 which are coaxially connected to each other. The oil suction member 225 fills the oil through hole 2226 and the oil guide hole 2234 and extends to the side of the support seat 222 away from the atomization chamber 201. In this way, when the oil suction member 225 in the atomization chamber 201 absorbs more condensate, the overflowing condensate can be guided through the oil through hole 2226 and the oil guide hole 2234 to the part of the oil suction member 225 located on the side of the support seat 222 away from the atomization chamber 201, thereby avoiding the problem of a large amount of condensate deposited in the atomization chamber 201 causing oil flying and condensation cracking during suction, and avoiding the condensate from the atomization airway 102 when the electronic atomization device 10 is inverted, thereby improving the consumer's user experience.
[0059] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0060] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
