Description

As a popular alternative to cigarettes, they are a popular choice among smokers. Traditional electronic atomizers consist of an atomizer and a power supply unit. The atomizer contains an oil reservoir, which stores the atomizing medium. The power supply unit supplies power to the atomizer, allowing it to heat and vaporize the atomizing medium in the reservoir to create an aerosol for the user to inhale.

[0003] Existing electronic atomization devices are usually oil-fillable atomization devices or pre-oil-filled atomization devices. Therefore, in one case, when the oil filling plug is pulled out to open the oil filling hole to inject the atomizing medium, or when the oil filling is completed and the oil filling plug is covered, the air in the oil storage chamber will be compressed by the oil filling gun or the oil filling plug, so that the air pressure in the oil storage chamber will be greater than the external atmospheric pressure, causing the atomizing medium in the oil storage chamber to overflow into the air flow channel through the oil guide cotton under the action of the air pressure difference and cause oil leakage; or in another case, when the user uses the electronic atomization device to atomize and inhale the atomizing medium, the atomizing medium is continuously consumed, and the air contained in the oil storage chamber will also be quickly extracted, so that negative pressure is generated in the oil storage chamber, causing more atomizing medium to be sucked into the oil guide cotton under the action of negative pressure and overflow into the air flow channel, thereby causing oil leakage, resulting in a poor user experience for the user.

[0036] 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.

[0037] See Figures 1 to 4 , Figure 1 and Figure 2 FIG1 shows a schematic diagram of the appearance of the atomizer 10 in the electronic atomization device according to an embodiment of the present application. Figure 3 shows an exploded schematic diagram of the atomizer 10, Figure 4 The exploded schematic diagram of the internal structure of the above-mentioned atomizer 10 is shown in a cross-sectional view. The atomizer 10 provided in one embodiment of the present application includes a housing 100, an atomizer assembly 200 and an air storage assembly 300, wherein the housing 100 is provided with an oil filling hole 101 and an air outlet 102, the air outlet 102 is provided at the top of the housing 100, so that the top of the housing 100 forms a suction nozzle, and an oil filling plug 400 for closing the oil filling hole 101 is provided at the position of the oil filling hole 101; the atomizer assembly 200 and the air storage assembly 300 are both provided with Inside the shell 100, the atomizing assembly 200 and the inner wall of the shell 100 form an oil storage chamber 105 for storing the atomizing medium, and the atomizing assembly 200 has an air flow channel 201 connected to the air outlet 102. The oil storage chamber 105 is connected to the external environment through the air flow channel 201 and the air outlet 102. When the oil filling plug 400 is pulled out from the oil filling hole 101, the oil storage chamber 105 is connected to the external environment through the oil filling hole 101, so that the oil filling gun can inject the atomizing medium into the oil storage chamber 105 through the oil filling hole 101.

[0038] The atomizing assembly 200 is connected to the oil storage chamber 105, so that the atomized medium in the oil storage chamber 105 can be transmitted to the atomizing assembly 200, and the atomizing assembly 200 heats and atomizes the atomized medium to generate an aerosol, so that the aerosol can be discharged from the air outlet 102 for the user to inhale; the gas storage assembly 300 is provided with a pressure relief hole 301 and a gas storage chamber 302 connected to the oil storage chamber 105 through the pressure relief hole 301, so that when the air pressure in the oil storage chamber 105 is greater than the air pressure of the external environment (for example, when the grease gun injects the atomized medium into the oil storage chamber 105, or when the injection of the atomized medium is completed, ... When the oil filling plug 400 closes the oil filling hole 101), the gas in the oil storage chamber 105 can overflow from the oil storage chamber 105 into the air storage chamber 302 through the pressure relief hole 301, or when the air pressure in the oil storage chamber 105 is lower than the air pressure of the external environment (for example, when the user is inhaling), the gas temporarily stored in the air storage chamber 302 is replenished into the oil storage chamber 105 through the pressure relief hole 301 to maintain the air pressure balance between the oil storage chamber 105 and the external environment, thereby preventing the atomized medium in the oil storage chamber 105 from overflowing into the air flow channel 201 due to the pressure difference and causing leakage of the atomized medium.

[0039] Specifically, in one embodiment, the shell 100 includes a main body 110 and a bottom cover 120 that are detachably connected to each other. The bottom of the main body 110 is open, and the bottom cover 120 is detachably connected to the bottom of the main body 110 and closes the bottom opening of the main body 110. The shell 100 has a connecting column 103, which extends from the inner wall of the shell 100 toward the oil storage chamber 105. The air outlet 102 passes through the connecting column 103. A seal 130 is provided on the bottom cover 120, and the seal 130 is fitted with the inner wall of the main body 110. One end of the atomizer assembly 200 is inserted into the connecting column 103, and the other end is inserted into the seal 130, so that the atomizer assembly 200 can be firmly fixed in the shell 100 without being separated from the shell 100. Optionally, two electrodes 500 are embedded in the bottom cover 120 , and the two electrodes 500 are electrically connected to the atomizer assembly 200 and used to connect to the power supply unit so that the power supply unit and the atomizer assembly 200 can be electrically connected to each other.

[0040] like Figure 3 and Figure 4 As shown, in the embodiment shown in the figure, the atomizer assembly 200 includes a vent tube 210 and an atomizer core 220. The air flow channel 201 runs through the vent tube 210. The atomizer core 220 is disposed within the air flow channel 201 and is electrically connected to the electrode 500 via a wire. One end of the vent tube 210 is connected to the top of the housing 100, that is, inserted into the connecting post 103 at the top of the housing 100, and the other end is connected to the bottom of the housing 100, that is, inserted into the sealing member 130 and extends into the bottom cover 120.

[0041] Furthermore, if Figure 5 As shown, the atomizer core 220 includes an outer oil guide member 221, a bracket 222, an inner oil guide member 223, and a heating element 224 electrically connected to the power supply unit, which are coaxially nested in sequence along the radial direction of the vent tube 210 and from the outside of the air flow channel 201 to the inside of the air flow channel 201. The outer oil guide member 221 is attached to the inner wall of the vent tube 210. The vent tube 210 is provided with an oil through hole 211, and the bracket 222 is provided with an oil through hole 2221. The outer oil guide member 221 and the inner oil guide member 223 are both made of cotton sheets that are permeable to the atomizing medium, so that the oil storage chamber 105 is connected to the heating element 224 through the oil through hole 211, the outer oil guide member 221, the oil through hole 2221, and the inner oil guide member 223 in sequence.

[0042] In this way, through the above design, the atomizing core 220 is easily installed in the air flow channel 201 in the vent pipe 210, not only allowing the atomizing medium in the oil storage chamber 105 to flow to the heating element 224 through the oil through hole 211, the outer oil guide member 221, the oil through hole 2221 and the inner oil guide member 223 in sequence to be heated and atomized by the heating element 224, but also because the outer oil guide member 221 and the inner oil guide member 223 have the function of locking oil, the atomizing medium can be slowly penetrated, so that the atomizing medium can be prevented from flowing quickly from the oil storage member to the heating element 224, and leakage of the atomizing medium can be prevented to a certain extent.

[0043] In order to fix the gas storage assembly 300 in the housing 100, refer to Figure 4 In a preferred embodiment, the housing 100 has a fixing post 104, which extends from the inner wall of the housing 100 toward the oil storage cavity 105, and the gas storage assembly 300 is partially inserted into the fixing post 104. In the specific structure of the gas storage assembly 300, as shown in FIG. Figure 5 As shown, the air storage assembly 300 includes a pressure relief valve 310 and an airbag 320. The airbag 320 is accommodated in the fixed column 104 and surrounds an air storage chamber 302. One end of the airbag 320 is open and the other end is closed. The pressure relief valve 310 is inserted into the opening of the airbag 320 and closes the opening. The pressure relief hole 301 is opened on the pressure relief valve 310.

[0044] More specifically, the fixing post 104 extends from an inner wall near the suction nozzle into the oil storage cavity 105 and extends to near the bottom of the oil storage cavity 105 . The pressure relief valve 310 is connected to the bottom end of the fixing post 104 .

[0045] In one embodiment, Figure 6 As shown, the pressure relief valve 310 includes a main body 311 and a plug-in portion 312 connected to one end of the main body 311. The outer diameter of the plug-in portion 312 is smaller than the outer diameter of the main body 311, and the plug-in portion 312 is inserted into the opening of the airbag 320 with an interference fit. The end of the airbag 320 with an opening is interference fitly connected to the inner wall of the fixing column 104.

[0046] Preferably, the airbag 320 is made of an elastic material that can undergo elastic deformation, so that when the air storage chamber 302 is filled with gas, the airbag 320 can expand; when the air storage chamber 302 is not filled with gas, the airbag 320 can shrink.

[0047] More preferably, the main body 311 has an accommodating cavity 303 connected to the air storage cavity 302, and the pressure relief hole 301 is set on the outer peripheral surface of the main body 311 and connected to the accommodating cavity 303. There are multiple pressure relief holes 301, and the multiple pressure relief holes 301 are spaced apart in the circumferential direction of the pressure relief valve 310.

[0048] In this way, through the above-mentioned setting, the air storage component 300 can close the opening at the lower end of the fixed column 104, and the aperture of the pressure relief hole 301 can also be set to be larger, so that the gas in the oil storage chamber 105 can preferentially enter the pressure relief valve 310 and enter the air storage chamber 302 without entering the fixed column 104, and by enabling the airbag 320 to expand or contract, the air storage chamber 302 can accommodate enough gas, thereby ensuring that the internal and external air pressures of the oil storage chamber 105 and the external environment are balanced.

[0049] Furthermore, the main body 311 of the pressure relief valve 310 is designed to be tapered, with the outer diameter of the main body 311 gradually decreasing from the closed end of the airbag 320 toward the open end of the airbag 320. This design expands the space in the oil storage chamber 105, allowing more gas to accumulate near the pressure relief hole 301, thereby allowing the gas to more easily pass through the pressure relief hole 301 and enter the air storage chamber 302.

[0050] The electronic atomization device provided in this application achieves equilibrium between the air pressure in the oil storage chamber 105 and the air pressure in the external environment according to the following principles:

[0051] In one scenario, when a user uses a grease gun to inject atomized medium into the oil storage chamber 105, or when the atomized medium is injected and the oil filling plug 400 is used to seal the oil filling hole 101, the air in the oil storage chamber 105 is compressed by the grease gun or the oil filling plug 400, causing the air pressure in the oil storage chamber 105 to be greater than the external atmospheric pressure. At this time, because the air storage assembly 300 is provided, the gas in the oil storage chamber 105 can preferentially enter the air storage chamber 302 of the air storage assembly 300 through the pressure relief hole 301, and expand the airbag 320, thereby balancing the air pressure in the oil storage chamber 105 with the air pressure of the external environment, thereby preventing the atomized medium in the oil storage chamber 105 from overflowing into the air flow channel 201 due to the pressure difference, thereby preventing the atomized medium from leaking.

[0052] In another case, when the user uses an electronic atomization device to atomize and inhale the atomizing medium, the atomizing medium is continuously consumed, and the air contained in the oil storage chamber 105 will also be quickly extracted. At this time, it is precisely because of the existence of the gas storage component 300 that the gas originally contained in the gas storage chamber 302 can be quickly replenished into the oil storage chamber 105, so that the air pressure in the oil storage chamber 105 is balanced with the air pressure of the external environment. It can also avoid the negative pressure generated in the oil storage chamber 105, which will cause more atomizing medium to be sucked into the outer oil guide part 221 and the inner oil guide part 223 under the action of the negative pressure and overflow into the air flow channel 201, thereby avoiding the leakage of the atomizing medium.

[0053] It can be seen that the atomizer provided by the present application and the electronic atomization device including the atomizer can ensure that the air pressure in the oil storage chamber 105 is balanced with the air pressure of the external environment, whether when injecting the atomizing medium or when completing the injection of the atomizing medium and closing the oil filling plug, or when suction is performed, thereby avoiding the risk of leakage of the atomizing medium and effectively improving the user experience.

[0054] Finally, it should be noted that the various technical features of the above-described embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above-described 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.

[0055] 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.
