Description

Technical Field

[0001] The utility model belongs to the technical field of electronic cigarettes, and in particular relates to a pressure relief atomization core structure of an electronic cigarette. Background Art

[0002] Electronic cigarettes use a heating wire to heat the e-liquid, creating a vaporized vapor. They typically consist of a casing, a mouthpiece, a dust filter, a fragrance box, a music mechanism, LEDs, a power supply, and a cap. When the mouthpiece is puffed on, negative pressure is generated inside the cigarette, opening the fragrance box lid. Air enters the cigarette and acts as a carrier for the aroma, which is then inhaled. The fragrance box lid opens and the power supply turns on, the music mechanism plays, and the LEDs flash.

[0003] Because the atomization chamber is connected to the air inlet and mouthpiece—that is, the oil and gas circuits are interconnected—existing e-cigarettes, while the air circuit needs to remain unobstructed, are susceptible to atomized liquid leaking from the air inlet and mouthpiece if the external air pressure is low. This leaked atomized liquid can contaminate the product and packaging, and can also easily contaminate other objects. For example, when traveling by airplane or being transported by aircraft, the external air pressure is low while the internal pressure of the e-cigarette is high, making atomized liquid more likely to leak.

[0004] To overcome the above technical problems, for example, a leak-proof electronic cigarette disclosed in Chinese patent document No. CN221059603U includes a mouthpiece, a shell, a liquid storage component, an atomizing core and a controller. The mouthpiece is connected to the shell, and the shell is provided with a storage cavity. The liquid storage component includes a accommodating tube, a first multi-porous liquid pipette and a second multi-porous liquid pipette. The accommodating tube is located in the storage cavity, the first multi-porous liquid pipette is located in the accommodating tube, and the first multi-porous liquid pipette is provided with a accommodating cavity; the second multi-porous liquid pipette is located in the accommodating cavity and contacts with the first multi-porous liquid pipette, and the second multi-porous liquid pipette is provided with an atomizing cavity. A first pressure relief space is formed between the first multi-porous liquid pipette and the second multi-porous liquid pipette, and the first pressure relief space is connected to the mouthpiece; the atomizing core is located in the atomizing cavity and contacts with the second multi-porous liquid pipette to atomize the atomized liquid at the second multi-porous liquid pipette; the controller is electrically connected to the atomizing core for controlling the operation of the atomizing core. By installing a first and second multi-porous pipette tubes that cooperate with each other within the housing tube, with the second multi-porous pipette tube located within the housing chamber and in contact with the first multi-porous pipette tube, a first pressure relief space is formed between the first and second multi-porous pipette tubes, which is connected to the mouthpiece. Therefore, when the present invention is placed in an environment with low external air pressure, such as an airplane, air in the first pressure relief space can be released through the mouthpiece, preventing atomized liquid from leaking out of the first and second multi-porous pipette tubes, thereby preventing liquid leakage.

[0005] For example, the Chinese patent document CN221241704U discloses an electronic cigarette with a negative pressure oil leakage prevention structure, which includes a housing, an oil storage tank, and a mouthpiece. The oil storage tank is mounted on the top of the housing, and the mouthpiece is mounted on the top of the oil storage tank. A filter structure is provided inside the mouthpiece, and a pressure relief structure is provided on one side of the interior of the oil storage tank. The filter structure includes a fixed shell, a box body, a guide groove, a filter element, and oil-absorbing cotton. The fixed shell is fixed to the interior of the mouthpiece, and the box body is fixed to the interior of the fixed shell. The oil storage tank is connected to the external environment through an air hole. Excessive atmospheric pressure pushes the plug plate and the spacer ring apart, and the air is discharged through the air hole, reducing the pressure inside the oil storage tank. This realizes the internal pressure relief function of the device, facilitates the discharge of air inside the device, balances the pressure inside and outside the device, prevents smoke oil leakage, and enhances the functionality of the device.

[0006] For another example, Chinese patent publication CN221330258U discloses an automatic pressure-relieving electronic cigarette comprising: a housing, an interior of which is provided a smoking passage and an air intake passage; and a pressure-relieving assembly, comprising an air chamber, within which is mounted a movable piston. The movable piston, when in a movable state, dissipates pressure in the air intake passage, thereby connecting the smoking passage and the air intake passage. When gas enters the electronic cigarette due to swinging or collision, the microphone sensor senses the airflow and automatically turns the electronic cigarette on, which can easily cause the atomizer core to burn. Therefore, this solution isolates the microphone sensor so that it only triggers airflow during inhalation, putting it into operation. The microphone sensor 11 senses the incoming airflow when the user is in use. When the user inhales, the airflow washes out the airflow through the inhalation passage on the housing. When the airflow is washed out, the pressure-relieving assembly is triggered, causing the movable piston 7 mounted within the air chamber to move. The movable piston 7 then causes the microphone sensor to sense the airflow, thereby turning the electronic cigarette on. This solution effectively prevents the occurrence of accidental operation of the microphone sensor 11 that is not triggered by the user.

[0007] In the above-mentioned patent documents, the disclosed technical solutions all utilize a pressure relief structure to achieve pressure relief inside the oil chamber. However, the technical solution of publication number CN221059603U utilizes a first pressure relief space, a second pressure relief space, and a cutout on the shell to achieve communication between the inside of the shell and the outside world to achieve pressure relief. The structure is complex, and the use of the cutout method may also cause oil leakage. For the technical solution disclosed in publication number CN221241704U, the pressure relief structure includes an air hole, a spacer ring, a plug plate, a limit frame, a fence net, and a spring. The air hole is opened at the top of the oil storage tank, and a spacer ring is fixed inside the air hole. The oil storage tank is connected to the external environment through the air hole. Excessive atmospheric pressure pushes the plug plate and the spacer ring to separate, and the air is discharged through the air hole to reduce the pressure inside the oil storage tank. A spring is fixed on one side of the limit frame, a plug plate is fixed on one side of the spring, and a fence net is installed on one side of the air hole. The pressure relief structure is equipped with a spring. Due to the small size of the pressure relief structure, the spring structure is even smaller, resulting in a complex structure and difficulty in assembly. Regarding the solution disclosed in patent document CN221330258U, a piston and gear are actually arranged in the cavity, and the gear structure is used to drive the piston to achieve the pressure relief function. The gear and other structures are assembled in a small space, resulting in a complex structure and difficult assembly. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0036] In one embodiment of the pressure relief atomizing core structure of the electronic cigarette of the present invention, please refer to Figures 1 to 8. The electronic cigarette pressure relief atomization core structure of this embodiment is used to be arranged in the oil chamber of the electronic cigarette, and can heat the tobacco oil in the oil chamber and atomize it during the inhalation process. Specifically, it includes a shell seat 100 and an atomization core 200. The atomization core 200 is connected to the shell seat 100. A flue 101 is provided in the shell seat 100 for connecting to the suction nozzle of the electronic cigarette. Therefore, the negative pressure formed by the suction nozzle allows the atomized tobacco oil to enter the human oral cavity through the flue 101. A number of pressure relief holes 102 are also provided on the outside of the shell seat 100. The pressure relief holes 102 are connected to the flue 101. A breathable valve 300 is provided in the pressure relief hole 102, and the breathable valve 300 only allows air to pass through. Since the atomizing core structure of this embodiment is provided with a pressure relief hole 102 connected to the suction nozzle, specifically, the pressure relief hole 102 is provided on the shell seat 100, thus replacing the existing electronic cigarette that provides a pressure relief structure on the electronic cigarette shell (oil chamber), the structure of the electronic cigarette can be simpler, assembly is more convenient, and the cost is lower. In addition, the pressure relief is achieved by connecting the channel of the suction nozzle with the pressure relief hole, and a breathable valve 300 is provided in the pressure relief hole 102. The use of the breathable valve that only allows air to pass through to relieve pressure not only prevents oil leakage but also ensures the pressure relief effect. Therefore, when smoking the electronic cigarette, the amount of smoke can be increased and the taste can be improved. Furthermore, after the pressure in the oil chamber of the electronic cigarette reaches equilibrium with the external air pressure, the breathable valve 300 will not have the problem of frequent air passing through. The air pressure in the oil chamber will not change when the electronic cigarette is placed in any state, further preventing the problem of oil leakage.

[0037] Further, refer to Figure 2 A step hole 103 is further provided on the outside of the pressure relief hole 102, and the air valve 300 is provided in the step hole 103. In this embodiment, the step hole 103 is used to limit and fix the air valve 300 to prevent the air valve 300 from falling into the oil chamber of the electronic cigarette.

[0038] Further, refer to Figure 1 and Figure 5 The air-permeable valve 300 includes a semi-permeable membrane 310 that is permeable to air but impermeable to oil, and a plug 320. The plug 320 compresses the semi-permeable membrane 310 in the stepped hole 103 and is provided with an air-through hole 321. Specifically, the plug 320 can be a silicone sleeve.

[0039] Furthermore, the housing base 100 is equipped with four pressure relief holes 102, each of which is equipped with a breathable valve 300, further enhancing the pressure relief effect. Furthermore, the outer surface of the housing base 100 is designed in a conical structure, with the pressure relief holes 102 positioned perpendicular to the conical surface. This conical structure facilitates connection with the e-cigarette mouthpiece. Positioning the pressure relief holes 102 perpendicular to the conical surface ensures the effective depth of the stepped hole 103, allowing the plug 320 to fully fit within the stepped hole 103.

[0040] A specific embodiment of the connection between the atomizer core 200 and the housing base 100; please refer to Figure 1 A connecting sleeve 110 extends from one end of the outer shell 100, and a plurality of oil inlets 111 are provided on the outside of the connecting sleeve 110. The atomizer core 200 includes an atomizer seat 201, a first oil storage cotton 202, a first oil guide cotton 203 and a first electric atomizer assembly 204. The atomizer seat 201 is provided with a positioning portion 205 positioned on the connecting sleeve 110, and an extension portion 206 is provided at the end of the positioning portion 205. The extension portion 206 and the inner side of the connecting sleeve 110 form an oil storage cavity 112, and the first oil storage cotton 202 is provided in the oil storage cavity 112. The extension portion 206 is provided with a first oil guide hole 207; the first oil guide cotton 203 wraps the first electric atomizer assembly 204 and is installed in the atomizer seat 201. In this way, the atomizer core 200 and the outer shell 100 are connected as one body. In this embodiment, the electronic cigarette pressure relief atomization core structure of this embodiment is installed in the oil chamber of the electronic cigarette. The tobacco oil in the oil chamber enters from the oil inlet 111 and is adsorbed in the first oil storage cotton 202. The tobacco oil stored in the first oil storage cotton 202 enters the first oil guide cotton 202 through the first oil guide hole 207. Therefore, after the first electric heating atomization component 204 is powered on, the tobacco oil in the first oil guide cotton 202 can be heated and atomized.

[0041] Going further, refer to Figure 1 and Figure 2 A support ring 208 is further provided in the atomizer seat 201, through which the first oil-conducting cotton 203 passes. This creates a gap between the first oil-conducting cotton 203 and the inner wall of the atomizer seat 201, where air can be stored. Therefore, when smoking, air is sucked out, thereby forming a large amount of smoke, which in turn improves the taste.

[0042] Further, refer to Figure 4 The extension portion 206 is provided with an opening groove 209 , and the first oil-conducting cotton 203 extends from the opening groove 209 and contacts the first oil-storing cotton 202 , so that the smoke oil in the first oil-storing cotton 202 can flow smoothly to the first oil-conducting cotton 203 .

[0043] Further, another embodiment of the connection between the atomizer core 200 and the housing base 100; specifically, please refer to Figures 5 to 8 The atomizer core 200 includes a sleeve 210, a second oil storage cotton 220, an atomizer tube 230, a second oil guide cotton 240, and a second electric atomizer assembly 250. One end of the sleeve 210 is sleeved on one end of the outer shell 100. The sleeve 210 is provided with a plurality of oil inlet holes 211. The second oil storage cotton 220 wraps the atomizer tube 230 and is installed in the sleeve 210. The atomizer tube 230 is provided with a second oil guide hole 231. The second oil guide cotton 240 wraps the second electric atomizer assembly 250 and is installed in the atomizer tube 230. The atomizer tube 230 is also provided with an air avoidance groove 232 for preventing the second oil guide cotton 240 from contacting the second oil storage cotton 220.

[0044] Further, refer to Figure 5 A limiting sleeve 212 is further provided at one end of the sleeve 210 closer to the outer shell seat 100 for limiting the second oil storage cotton 220 to prevent the second oil storage cotton 220 from entering the guide shell seat 100.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
