Description

Technical Field

[0001] The present application relates to the field of electronic atomization technology, and in particular to 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, for most types of electronic atomizer devices currently on the market, after the user stops inhaling, the residual aerosol in the atomizer chamber will condense into condensate after cooling. After a long time, a large amount of condensate will be deposited in the atomizer chamber, causing the user to produce flying oil (i.e. condensate splashing) and gurgling sound (condensation cracking) when inhaling subsequently. In addition, when the electronic atomizer device is inverted, the condensate will also flow out of the airway. For electronic atomizer devices with smaller atomizer chamber space, the above phenomenon is particularly obvious, which seriously affects the consumer's user experience, causing users to lose trust in the product and no longer choose to continue using it, thereby affecting the product's activity in the market. Utility Model Content

[0036] 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.

[0037] 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.

[0038] See Figures 1 to 3 , Figure 1 FIG. 1 shows a schematic diagram of the appearance of an electronic atomization device 10 in one embodiment of the present application. Figure 2 shows a top view of the electronic atomization device 10, Figure 3The electronic atomization device 10 is shown in a cross-sectional view of the internal structure. The electronic atomization device 10 provided in one embodiment of the present application includes a housing 100, a sealing assembly 200, an atomization core 300, a battery 400 and an oil suction member 500, wherein the sealing assembly 200 is arranged in the housing 100 and forms an oil storage chamber 101, an oil suction chamber 102 and a mounting position 103 which are isolated from each other with the inner wall of the housing 100. The oil storage chamber 101 is used to accommodate the atomization medium. The sealing assembly 200 is provided with an atomization chamber 201 which is connected to the oil storage chamber 101 and the oil suction chamber 102. The atomization core 300 is provided in the atomization chamber 201, and the atomization core 300 is used to The atomizing medium flowing into the oil storage chamber 101 is heated and atomized to generate an aerosol for the user to inhale; a portion of the oil suction component 500 is arranged in the atomizing chamber 201, and the other portion passes through the sealing assembly 200 and extends into the oil suction chamber 102, which is used to absorb the condensate formed after the aerosol in the atomizing chamber 201 is cooled, and guide the condensate from the atomizing chamber 201 to the oil suction chamber 102 to avoid a large amount of condensate being deposited in the atomizing chamber 201; the battery 400 is arranged in the installation position 103 and is electrically connected to the atomizing core 300 for powering the atomizing core 300.

[0039] Specifically, in the direction of the gas path of the electronic atomization device 10, combined with Figure 3 and Figure 4 As shown, a suction nozzle 600 is provided on the top of the shell 100, and an air outlet 601 is opened in the suction nozzle 600. An atomizing air channel 104 is opened on the shell wall of the shell 100. The atomizing air channel 104 runs through the shell 100 and is connected to the air outlet 601. The oil storage chamber 101 is connected to the atomizing air channel 104 through the atomizing chamber 201.

[0040] Further, see Figure 3 The oil suction chamber 102 is also provided with an airflow sensing assembly 700, which includes a circuit board 720 and an airflow sensor 710 provided on the circuit board 720. The circuit board 720 is electrically connected to the airflow sensing assembly 700 and is also electrically connected to the battery 400. The airflow sensor 710 is used to sense the negative pressure generated by the airflow when the user uses the electronic atomization device 10 to inhale, and trigger the circuit board 720 to control the battery 400 to power the atomization core 300, so that the atomization core 300 can heat the atomization medium flowing into itself. Therefore, in order to enable the airflow sensor 710 to sense the negative pressure generated by the airflow, combined with Figure 3 and Figure 5 As shown, an air inlet 106 connected to the oil suction chamber 102 is provided at the bottom of the shell 100, and an air flow sensing channel 105 isolated from the atomizing air channel 104 is also provided on the shell wall of the shell 100. One end of the air flow sensing channel 105 is connected to the air inlet 106 through the oil suction chamber 102, and the other end is connected to the air outlet 601.

[0041] Thus, when a user inhales, the atomized medium flows from the oil storage chamber 101 to the atomizer core 300 located in the atomizer chamber 201. The atomizer core 300 heats the atomized medium and atomizes it, generating an aerosol that can then be accumulated in the atomizer chamber 201. Simultaneously, outside air can enter the oil suction chamber 102 from the air inlet 106, and then from the oil suction chamber 102 into the atomizer chamber 201. After mixing with the aerosol in the atomizer chamber 201, it can then be discharged from the electronic atomizer device 10 through the air outlet 601 along the atomizing airway 104, and then inhaled into the mouth of the user. Furthermore, outside air can flow from the oil suction chamber 102 to the airflow sensing channel 105, forming an airflow. This causes the airflow sensor 710 to sense the negative pressure generated by the airflow, thereby triggering the circuit board 720 to control the battery 400 to power the atomizer core 300, achieving the function of automatically powering when inhaling and stopping powering when inhaling.

[0042] More specifically, see Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The shell 100 has a partition 107, which extends from the inner top wall of the shell 100 in a direction away from the suction nozzle 600 and is connected to the sealing assembly 200, so that the inner cavity of the shell 100 is divided into an oil storage cavity 101 and a mounting position 103 by the partition 107, and the atomization air channel 104 and the airflow sensing channel 105 are opened in the partition 107 and pass through the upper and lower ends of the partition 107.

[0043] In this way, by opening the atomizing air duct 104 and the airflow sensing channel 105 in the partition 107, on the one hand, the internal structure of the electronic atomizing device 10 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 atomizing device 10, avoids the problem of assembly errors, saves the material of the center tube, and greatly reduces the production and manufacturing cost of the electronic atomizing device 10; on the other hand, hiding the atomizing air duct 104 in the shell wall of the shell 100 can highlight the novelty and differentiation of the electronic atomizing device, avoid the problem of product homogeneity, and improve the market competitiveness of the product.

[0044] It is understood that in other embodiments, the battery 400 can be disposed outside the housing 100 or the electronic atomization device 10 can be connected to an external power source for operation. That is, the partition 107 is not disposed within the housing 100, so that the sealing assembly 200 and the inner wall of the housing 100 only form the oil storage chamber 101 and the oil suction chamber 102. This is not limited here. However, by providing the partition 107, the battery 400 is also accommodated within the housing 100. In addition to effectively protecting the battery 400 by the housing 100, the electronic atomization device 10 can also be powered and used without an external power source, which is clearly the optimal embodiment.

[0045] See Figure 8In terms of the structure of the sealing assembly 200, the sealing assembly 200 includes a sealing member 210 and a base 220. The sealing member 210 is made of a silicone material and fits the inner wall of the housing 100 with an interference fit, so that one side of the sealing member 210 and the inner wall of the housing 100 together form the oil storage chamber 101 and the mounting position 103. The base 220 is provided on the side of the sealing member 210 away from the oil storage chamber 101 and together with the sealing member 210 forms the atomization chamber 201; the atomization chamber 201 The cavity wall is provided with a first through hole 202 connected to the oil suction cavity 102; a portion of the oil suction member 500 is provided in the atomizing cavity 201, and the other portion fills the first through hole 202 and extends into the oil suction cavity 102, so that there is no gap between the oil suction member 500 and the hole wall of the first through hole 202, which can ensure that the condensed liquid absorbed by the oil suction member 500 can be completely guided by the oil guide member to the portion of the oil guide member located in the oil suction cavity 102, thereby preventing the condensed liquid from leaking along the hole wall of the first through hole 202. It should be noted that the cavity wall of the atomizing cavity 201 includes the bottom wall and side walls of the atomizing cavity 201. Figure 8 In the embodiment shown in , the first through hole 202 starts from the bottom wall of the atomizing chamber 201 , and may also be opened on the side wall of the atomizing chamber 201 , which is not limited here.

[0046] Optionally, in order to more firmly fix the oil absorbing member 500 and to seal the airflow sensor 710 to prevent condensation from damaging the airflow sensor 710, the airflow sensing assembly 700 further includes a sealing gasket 730. One side of the sealing gasket 730 is adhered to the side of the circuit board 720 facing the sealing assembly 200, and the other side is adhered to the base 220. The sealing gasket 730 is provided with a second through hole 701 that passes through its opposite sides and the circuit board 720. The second through hole 701 is coaxially arranged with the first through hole 202. The oil absorbing member 500 further penetrates and fills the second through hole 701, so that part of the surface of the oil absorbing member 500 is adhered to the hole walls of the first through hole 202 and the second through hole 701, thereby preventing relative movement relative to the sealing assembly 200 and the airflow sensing assembly 700.

[0047] For details on the structure of the oil absorbing member 500, please refer to Figure 8 The oil suction member 500 includes an oil suction portion 510, an oil guide portion 520, and an oil lock portion 530. The oil suction portion 510 is disposed within the atomizing chamber 201, and the oil lock portion 530 is disposed within the oil suction chamber 102. The oil guide portion 520 fills the first through-hole 202 and the second through-hole 701. One end of the oil guide portion 520 is connected to the oil suction portion 510, and the other end is connected to the oil lock portion 530. The oil suction portion 510 is used to absorb condensed liquid into the oil suction member 500, and the oil guide portion 520 is used to guide the condensed liquid from the atomizing chamber 201 to the oil lock portion 530 located in the oil suction chamber 102. The oil lock portion 530 is used to lock the condensed liquid guided into itself, thereby preventing the condensed liquid from leaking out of the air inlet 106 of the housing 100.

[0048] In a specific embodiment, the oil absorption part 510, the oil guide part 520 and the oil lock part 530 are made of different materials, so that the oil absorption part 510, the oil guide part 520 and the oil lock part 530 can respectively have the functions of absorbing oil, guiding oil and locking oil. Specifically, the material of the oil absorption part 510 is compressed cotton, commonly known as needle cotton. The main raw material of needle cotton includes polyester fiber. It is a structure that directly uses needles to punch fibers into flakes without weaving. Its main characteristics include water and oil absorption, high air permeability, and large dust holding capacity, so it can absorb condensate well; the material of the oil guide part 520 is vertical fiber fluffy cotton. The vertical fiber fluffy cotton includes a plurality of interconnected fibers. All fibers form a plurality of gaps extending in the vertical direction (the direction in which the central axis of the first through hole 202 extends), so that the oil absorption part 510 can absorb oil and water. The condensate in the part 510 can be guided from the oil absorption part 510 to the oil locking part 530 along the above-mentioned gap; the material of the oil locking part 530 is transversely laminated fiber composite cotton, and the transversely laminated fiber cotton includes multiple layers of fibers that are interconnected and stacked vertically, so that the transversely laminated fiber composite cotton has multiple gaps extending in the transverse direction (i.e., perpendicular to the vertical direction), so that the condensate guided to the oil locking part 530 can basically only flow in the transverse direction, thereby being locked in the oil locking part 530 and will not seep out of the shell 100 in the vertical direction.

[0049] Preferably, the oil locking portion 530 is designed to have a larger volume, specifically, the cross-sectional profile of the oil locking portion 530 is consistent with the cross-sectional profile and size of the inner cavity of the shell 100, so that the side walls and bottom walls of the oil locking portion 530 are both attached to the walls of the oil suction cavity 102, thereby enabling the oil locking portion 530 to fully absorb the condensate introduced into itself, and thereby achieve an oil locking effect in which the condensate will not overflow.

[0050] Furthermore, the applicant tested the structure of the above-mentioned oil-absorbing member 500 using a suction resistance meter. The test results show that when the oil-absorbing member 500 absorbs condensed liquid or when it does not absorb condensed liquid, the airflow does not pass through the oil-absorbing member 500. Therefore, the oil-absorbing member 500 with the above-mentioned structure does not affect the suction resistance of the electronic atomization device 10. It can be seen that by providing the oil-absorbing member 500 with the above-mentioned structure, the condensed liquid deposited in the atomization chamber 201 can be absorbed by the oil-absorbing member 500 and diverted from the oil-absorbing portion 510 to the oil-locking portion 530. At the same time, the condensed liquid in the oil-locking portion 530 can be prevented from overflowing, thereby solving the problem of oil flying and condensation cracking caused by the deposition of condensed liquid in the atomization chamber 201, as well as the problem of condensed liquid flowing out of the airway when the electronic atomization device 10 is inverted, thereby improving the user experience of consumers.

[0051] 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.

[0052] 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. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
