[0046] The electronic atomization devices currently on the market include an atomization component and a power supply component, and the power supply component is used to supply power to the atomization component. The atomization component is provided with an oil storage chamber, and the atomization medium in the oil storage chamber is atomized to form an aerosol for the user to inhale. However, during the atomization process, the atomization medium in the oil storage chamber often leaks to the outer surface of the atomization component, resulting in extremely poor user experience, and the taste of the aerosol before and after the user inhales is significantly different.

[0047] Based on this, an embodiment of the present application provides an oil storage component and an electronic atomization device thereof, wherein the electronic atomization device includes an oil storage component, an atomization component and a power supply component, wherein the power supply component can supply power to the atomization component to atomize an atomizing medium; wherein the oil storage component is used to store the atomizing medium, and the atomizing medium inside the oil storage component can provide the atomizing medium to the atomizing component when the atomizing medium is needed for atomization to produce an aerosol, thereby avoiding leakage of the atomizing medium in the electronic atomization device and the occurrence of a significant difference in the taste of the aerosol before and after atomization.

[0048] The present application is described in detail below with reference to the accompanying drawings and embodiments.

[0049] See also Figure 1 to Figure 2 , Figure 1 is a structural cross-sectional view of an electronic atomization device provided in one embodiment of the present application; Figure 2 This is provided by an embodiment of the present application Figure 1 A schematic diagram of the structural decomposition of the electronic atomization device shown. In the present embodiment, an electronic atomization device is provided, which can be used in the fields of beauty, medical treatment, electronic cigarettes, etc. The electronic atomization device includes an oil storage component, an atomization component and a power supply component. The oil storage component is used to store the atomization medium and is in liquid communication with the atomization component so that when the atomization component lacks the atomization medium, the atomization medium is provided to it to ensure the normal atomization work; the power supply component is electrically connected to the atomization component to supply power to the atomization component. The atomization component is used to atomize the atomization medium to form an aerosol when power is turned on. The atomization medium can be a liquid medicine formed by dispersing a certain medicine in a liquid solvent, an oil with added aroma components, or any other liquid suitable for atomization, such as tobacco oil.

[0050] See also Figures 1 to 3The electronic atomization device includes: an oil storage component 200, an atomization component 100 and a first sealing component 23. The oil storage component 200 is provided with an extension portion 206 and a first oil storage cavity 2001. The extension portion 206 extends away from the first oil storage cavity 2001; the atomization component 100 is provided with a first connecting port 101 and a second oil storage cavity 1001. The first connecting port 101 is connected to the second oil storage cavity 1001. The first connecting port 101 is configured to be connected to the extension portion 206 so that the first oil storage cavity 2001 and the second oil storage cavity 1001 are liquid-connected; the first sealing component 23 is molded on the outer side walls of the first connecting port 101 and the extension portion 206 by in-mold injection molding so that the oil storage component 200 and the atomization component 100 are sealed and fused together. It can also be understood in this way: the atomization component 100 and the oil storage component 200 are separated into two parallel independent components, and the atomization component 100 and the oil storage component 200 are welded and sealed into one body through the first sealing member 23 to avoid the phenomenon of leakage of the atomized medium due to extrusion deformation and breakage during transportation. At the same time, the atomization component 100 and the oil storage component 200 are respectively provided with a second oil storage chamber 1001 and a first oil storage chamber 2001. When the second oil storage chamber 2001 does not have enough atomized medium to atomize, the first oil storage chamber 2001 can supply the atomized medium to the second oil storage chamber 1001, thereby extending the shelf life of the atomized medium in the first oil storage chamber 2001, while maintaining a good aerosol taste.

[0051] In some embodiments, Figure 3 As shown, the angle a between the axis of the extension part 206 and the axis of the first oil storage chamber 2001 is 0-90°. The angle between the axis of the extension part 206 and the axis of the first oil storage chamber 2001 can increase the flow rate of the atomized medium in the first oil storage chamber 2001 to the second oil storage chamber 1001, and avoid waste caused by excessive atomized medium remaining in the first oil storage chamber 2001. At the same time, because of the angle, during the diversion process, the speed at which air bubbles are generated and diverted to the first oil storage chamber 2001 can be increased to increase the speed at which the atomized medium is diverted to the second oil storage chamber 1001. The angle between the axis of the extension part 206 and the axis of the first oil storage chamber 2001 can be 10°, 20°, 30°, 40°, 50°, 60°, 70°, 80°

[0052] See also Figure 2 The power supply assembly 300 includes a first shell 31 and a second shell 37, and the first shell 31 and the second shell 37 cover each other to form a power supply storage chamber 3001; the atomizer assembly 100 is arranged in the power supply storage chamber 3001, and the oil storage assembly 200 is arranged outside the power supply storage chamber 3001, and the atomizer assembly 100 is liquid-connected with the oil storage assembly 200.

[0053] Specifically, the power supply assembly 300 includes a first shell 31 and a second shell 37 that cover each other on the left and right to form a power supply storage chamber 3001. The first shell 31 and the second shell 37 are both L-shaped structures, so the power supply storage chamber 3001 formed by the first shell 31 and the second shell 37 is an L-shaped structure; the atomizer assembly 100 is arranged in the L-shaped power supply storage chamber 3001, and the oil storage assembly 200 is arranged outside the L-shaped power supply storage chamber 3001, and the atomizer assembly 100 and the oil storage assembly 200 can be liquid-connected.

[0054] In this embodiment, the power supply assembly 300 also includes a first PCB board 33, a battery 34, a connecting column 38 and a second PCB board 35. The first PCB board 33 and the second PCB board 35 are respectively arranged at both ends of the battery 34. The first PCB board 33 and the second PCB board 35 are communicatively connected through the connecting column 38, and the connecting column 38 is arranged along the outer circumference of the battery 34. Therefore, both the communication connection and the electrical connection can be achieved through the connecting column 38, and the shaking of the battery 34 can be limited on the axis. The circuit connection between the first PCB board 33, the battery 34 and the second PCB board 35 does not require welding, and they are all squeeze-touch electrical connections. Therefore, the electrical connection is more stable, avoiding the phenomenon of circuit breaking due to shaking of the electronic atomization device during transportation or use. At the same time, manual welding is not required, reducing production costs.

[0055] In this embodiment, the power supply assembly 300 also includes a power supply upper base 32, which is arranged on the second PCB board 35. A power supply electrode 39 is welded on the second PCB board 35, and the power supply electrode 39 passes through the power supply upper base 32 and extends away from the power supply upper base 32.

[0056] In this embodiment, the L-shaped power supply storage chamber 3001 is divided into an upper storage chamber 30011 and a lower storage chamber 30012, the atomizer assembly 100 is arranged in the upper storage chamber 30011, the first PCB board 33, the battery 34 and the second PCB board 35 are arranged in the lower storage chamber 30012, the upper storage chamber 30011 and the lower storage chamber 30012 are isolated by the power supply upper seat 32, and the power supply electrode 39 passes through the power supply upper seat 32 and is electrically connected to the atomizer assembly 100, thereby avoiding damage caused by the aerosol condensate generated by the atomizer assembly 100 during operation leaking onto the battery 34 or the first PCB board 33.

[0057] In this embodiment, if Figure 2 As shown, decorative parts 36 are provided on the outer sides of the first shell 31 and the second shell 37. The decorative parts 36 can be stably connected to the first shell 31 and the second shell 37 by gluing, welding, etc. The decorative parts 36 can be made of leather, leather case, plastic simulated leather and other materials to enhance the feel of the electronic atomization device, such as anti-slip, heat insulation, etc.

[0058] In this embodiment, if Figure 1 As shown, the oil storage component 200 is arranged outside the L-shaped power supply capacity cavity 3001, that is, the oil storage component 200 is completely exposed outside the power supply component 300, and is combined with the power supply component 300 to form a square electronic atomization device. The overall design is good, and the user can observe the state of the atomization medium in the oil storage component 200 from the outside, such as the color change of the atomization medium, the remaining amount and other information, so that the user can use the electronic atomization device with more confidence.

[0059] Of course, in other embodiments, the oil storage assembly 200 can also be configured to be partially exposed outside the L-shaped structure power supply storage cavity 3001, so that the overall design of the electronic atomization device is stronger. This is not limited here.

[0060] The specific structure and function of the oil supply and storage assembly 200 are introduced below.

[0061] Please see further Figure 5 and Figure 7 , Figure 5 yes Figure 1 Schematic diagram of the intermediate oil storage assembly; Figure 7 yes Figure 5 The structural exploded diagram of the oil storage assembly is shown. In this embodiment, an oil storage assembly 200 is provided, and the oil storage assembly 200 includes a first oil hanging shell 20, a second oil hanging shell 21 and a second sealing member 22; the second oil hanging shell 21 is configured to be snap-fitted and connected with the first oil hanging shell 20 to form a first oil storage cavity 2001; the second sealing member 22 is configured to be formed between the first oil hanging shell 20 and the second oil hanging shell 21 by intramold injection molding, so that the first oil hanging shell 20 and the second oil hanging shell 21 are integrally sealed and molded, which not only has a good sealing effect, but also forms an integral body, avoiding the phenomenon of warping at the connection position due to compression deformation.

[0062] Specifically, the first oil hanging shell 20 and the second oil hanging shell 21 are covered and connected to each other, and the inner cavities of the first oil hanging shell 20 and the second oil hanging shell 21 are combined and connected to form a first oil storage chamber 2001, and the first oil storage chamber 2001 is used to store atomized medium. A second sealing member 22 is provided at the connection between the first oil hanging shell 20 and the second oil hanging shell 21, and the second sealing member 22 is molded at the connection between the first oil hanging shell 20 and the second oil hanging shell 21 by in-mold injection molding, so that the first oil hanging shell 20, the second sealing member 22 and the second oil hanging shell 21 are fused and sealed to form a whole, so as to prevent the atomized medium in the first oil storage chamber 2001 from leaking from the connection between the first oil hanging shell 20 and the second oil hanging shell 21, or to avoid leakage of the atomized medium caused by disassembly by the user, or to avoid leakage of the atomized medium caused by extrusion and deformation during transportation.

[0063] In this embodiment, if Figure 7As shown, a third filling groove 203 is provided on the end of the connecting end of the first oil hanging shell 20 and the second oil hanging shell 21, and a second filling groove 204 is provided on the end of the connecting end of the second oil hanging shell 21 and the first oil hanging shell 20. When the second oil hanging shell 21 is connected and covered with the first oil hanging shell 20, the third filling groove 203 and the second filling groove 204 are surrounded to form a filling cavity for in-mold injection molding of the second sealing member 22; it can also be understood that when the second oil hanging shell 21 is connected and covered with the first oil hanging shell 20, the third filling groove 203 and the second filling groove 204 form a filling cavity for in-mold injection molding of the second sealing member 22. The interconnected filling cavities are injected with molten plastic slurry, so that the molten plastic slurry is filled in the filling cavity to form a second sealing member 22. During the cooling process of the second sealing member 22, it is welded to the first oil hanging shell 20 and the second oil hanging shell 21 to form a whole. Therefore, the first oil hanging shell 20, the second sealing member 22 and the second oil hanging shell 21 are welded to form a whole, so the sealing effect is better, avoiding leakage of the atomized medium, and no silicone sealing ring is required, which can reduce costs and avoid the phenomenon of leakage of the atomized medium caused by assembly errors during the assembly process.

[0064] In this embodiment, the third filling groove 203 is arranged on the connecting end surface of the first oil hanging shell 20, and is recessed in the direction away from the second oil hanging shell 21; the second filling groove 204 is arranged on the connecting end surface of the second oil hanging shell 21, and is recessed in the direction away from the first oil hanging shell 20; the second rubber sealing component 22 is formed in the recess, and the second rubber sealing component 22 is welded to the first oil hanging shell 20 and the second oil hanging shell 21 to form a whole.

[0065] In this embodiment, the depression is V-shaped, and the large ends of the V-shaped grooves of the third filling groove 203 and the second filling groove 204 are relatively oriented, so that the second sealing member 22 is stably clamped in the third filling groove 203 and the second filling groove 204. Therefore, after welding, the bite force with the second oil hanging shell 21 and the first oil hanging shell 20 is stronger, the sealing effect is better, and the bonding force against compressive deformation and warping is stronger.

[0066] The recess may also be designed to be U-shaped, T-shaped, etc., which is not limited here.

[0067] In this embodiment, continue to see Figure 3 , Figure 5 and Figure 7As shown, the oil storage assembly 200 also includes an extension portion 206, which is arranged on one side of the oil storage assembly 200, and the extension portion 206 extends away from the first oil storage chamber 2001, and the extension portion 206 is used to connect with the liquid supply of the atomizer assembly 100; the extension portion 206 is provided with an oil outlet 205 connected to the first oil storage chamber 2001 and connected to the liquid supply of the atomizer assembly 100; the atomizing medium in the first oil storage chamber 2001 flows to the atomizer assembly 100 through the oil outlet 205 to participate in atomization. For example, in this embodiment, when the atomizer assembly 100 is about to run out of atomizing medium, the user can stand upside down or tilt it to allow the atomizing medium in the first oil storage chamber 2001 to flow to the atomizer assembly 100 to participate in atomization, thereby avoiding the phenomenon of the atomizer assembly 100 being burned. Since the atomizer assembly 100 and the oil storage assembly 200 are not kept in communication, liquid is supplied to the atomizer assembly 100 only when it needs it. Therefore, the aerosol generated by the atomization of the atomizer assembly 100 can be kept unchanged, the taste can be restored, and the user experience can be improved.

[0068] Specifically, the extension part 206 is arranged on one side of the upper end of the oil storage assembly 200, and extends out of the outer surface of the oil storage assembly 200, so as to facilitate the connection between the extension part 206 and the atomization assembly 100. The extension part 206 is provided with an oil outlet 205, and the oil outlet 205 is communicated with the first oil storage chamber 2001, so that the atomized medium in the first oil storage chamber 2001 is guided to the atomization assembly 100 through the oil outlet 205; the oil outlet 205 is connected to the end of the first oil storage chamber 2001 to form a trumpet-shaped smooth transition, so that the atomized medium in the first oil storage chamber 2001 can be smoothly guided to the atomization assembly 100 to participate in atomization, and at the same time, when there is less atomized medium in the first oil storage chamber 2001, the atomized medium can also be guided to the atomization assembly 100 to participate in atomization, so that the atomized medium is not wasted, and the atomized medium in the first oil storage chamber 2001 has a high utilization rate.

[0069] In this embodiment, see Figure 3As shown, a flow divider 201 is provided in the oil outlet 205, and the flow divider 201 extends into the first oil storage chamber 2001, thereby dividing the oil outlet 205 into at least two oil outlet grooves 2041. Therefore, when the atomized medium in the first oil storage chamber 2001 is directed to the atomization assembly 100, the electronic atomization device is tilted toward the atomization assembly 100, and the atomized medium may fill the oil outlet 205. At this time, the air in the atomization assembly 100 automatically selects the oil outlet groove 2041 with less atomized medium. 1 enters the first oil storage chamber 2001, while the other oil outlet grooves 2041 continue to guide the atomized medium to the atomizing assembly, thereby improving the guiding speed; at the same time, since the air enters the first oil storage chamber 2001 in the form of bubbles during the inclined guiding process, it can be guided and cut by the diverter 201, so that large bubbles become small bubbles and flow quickly into the first oil storage chamber 2001, thereby preventing large bubbles from blocking the oil outlet 205 and affecting the guiding effect of the atomized medium.

[0070] In this embodiment, the diversion portion 201 can be arranged along the axial direction of the electronic atomization device, that is, dividing the oil outlet 205 into two left and right oil outlet grooves 2041; it can also be arranged along the radial direction of the electronic atomization device, that is, dividing the oil outlet 205 into two upper and lower oil outlet grooves 2041; there is no limitation here.

[0071] In this example, see Figure 3 and Figure 7 As shown, the lower end of the oil storage assembly 200 is provided with an oil filling groove 25, and the user injects the atomized medium into the first oil storage cavity 2001 through the oil filling groove 25, so the oil storage assembly 200 can be reused, reducing the user's use cost. An oil filling plug 24 is provided in the oil filling groove 25, and the oil filling groove 25 is sealed by the oil filling plug 24 to prevent the atomized medium in the first oil storage cavity 2001 from leaking.

[0072] In this example, see Figure 3 The opening direction of the oil filling groove 25 is toward one side of the power supply component 300, and is in contact with the side wall of the power supply component 300, that is, the oil filling plug 24 is in contact with the side wall of the power supply component 300, so that the oil filling plug 24 is more stable and has a better sealing effect, and prevents the oil filling plug 24 from falling off due to shaking or temperature difference or atmospheric pressure difference during transportation, thereby ensuring that the oil storage component 200 has a better sealing effect and is safer to use.

[0073] In this example, please continue to refer to Figure 7At least two injection ports 202 are provided on the sidewalls of the third filling slot 203 and / or the second filling slot 204. The molten plastic slurry is injected into the filling cavity formed by the third filling slot 203 and the second filling slot 204 through the injection ports 202. Therefore, multiple injection ports 202 can allow the plastic slurry to be injected into the filling cavity from different directions, so that the second sealing member 22 and the first oil hanging shell 20 and the second oil hanging shell 21 are more evenly welded, with better effect and better sealing effect. The number of injection ports 202 can be 3, 4, 5, 6, etc., which is not limited here.

[0074] In the present application, the electronic atomization device further includes an atomization assembly 100, which is used to atomize the atomization medium to produce an aerosol for the user to inhale. Figure 4 and Figure 6 , Figure 4 yes Figure 1 Schematic diagram of the atomization component. Figure 6 yes Figure 4 The structural decomposition diagram of the atomizer assembly is shown; the atomizer assembly 100 includes an atomizer core 15, an atomizer shell 10 and a first base 11, one end of the atomizer shell 10 is an open end, and the other end is a mouthpiece 19, the atomizer core 15 is arranged in the atomizer shell 10, and the atomizer core 15 is fixedly connected to the first base 11, and the first base 11 is arranged at the open end of the atomizer shell 10, so the atomizer shell 10, the atomizer core 15 and the first base 11 are surrounded to form a second oil storage chamber 1001, and the second oil storage chamber 1001 is used to store the atomizer medium and the atomizer core 15, and the atomizer medium in the second oil storage chamber 1001 is supplied to the atomizer core 15 to be atomized into an aerosol, and the user can inhale the aerosol from the mouthpiece 19 to solve the problem of smoking addiction.

[0075] In this example, see Figure 4 The atomizer core 15 is covered with an atomizer sleeve 16, and the atomizer core 15 is fixed inside thereof by the atomizer sleeve 16, and the two ends of the atomizer sleeve 16 are respectively abutted against the mouthpiece 19 and the first base 11, so that the outside air enters from the first base 11, passes through the atomizer core 15 and merges with the aerosol, and is discharged from the upper end of the atomizer sleeve 16 and the mouthpiece 19, so that the aerosol can be smoothly delivered to the user's oral cavity, thereby improving the user experience.

[0076] In this embodiment, continue to refer to Figures 3 to 5 A second base 12 is sleeved on the outside of the first base 11, and a first filling groove 17 is provided between the second base 12 and the side wall of the atomizer housing 10. A third sealing member 13 is formed in the first filling groove 17 by an in-mold injection molding method, so that the third sealing member 13 is fused and sealed with the side wall of the atomizer housing 10, the first base 11 and the second base 12, so that the atomizer assembly 100 forms an integral structure that cannot be disassembled and is formed by in-mold injection molding.

[0077] In this example, see Figure 6 An oil-absorbing cotton 14 is arranged between the first base 11 and the second base 12. During the atomization process of the atomizer core 15, a small amount of aerosol condenses to produce condensate, which is absorbed by the oil-absorbing cotton 14 to prevent the condensate from leaking to the outside of the atomizer assembly 100.

[0078] In this example, see Figure 3 and Figure 6 The atomizing sleeve 16 is in contact with the cigarette holder 19 through the sealing seat to prevent the atomizing medium in the second oil storage chamber 1001 from leaking.

[0079] In the present embodiment, the third sealing member 13 surrounds the atomizing housing 10 and the second base 12, and the third sealing member 13 is also connected to an end face of the first base 11 away from the second oil storage chamber 1001. It can also be understood that the first filling groove 17 is surrounded by the atomizing housing 10, the second base 12, and the first base 11, and the first filling groove 17 is filled with molten plastic slurry of the third sealing member 13. Therefore, after the third sealing member 13 is formed, the third sealing member 13 and the atomizing housing 10, the second base 12, and the first base 11 are all in a fused state. Therefore, the third sealing member 13 is completely sealed in the connecting gap between the atomizing housing 10 and the first base 11, and the connecting gap between the first base 11 and the second base 12, to prevent the atomizing medium in the second oil storage chamber 1001 from leaking out of the atomizing assembly 100.

[0080] In this embodiment, an atomizing electrode is disposed on the second base 12 so that the atomizing electrode is stably electrically connected to the atomizing core 15 .

[0081] In this example, see Figure 3 and Figure 4 As shown, a first connecting port 101 is provided on the side wall of the atomizing housing 10, and the first connecting port 101 is communicated with the second oil storage chamber 1001. A second connecting port 201 is provided on the extending portion 206 of the oil storage assembly 200, and the first connecting port 101 is connected with the second connecting port 201, so that the oil storage assembly 200 and the atomizing assembly 100 are fixedly connected, so that the first oil storage chamber 2001 is communicated with the second oil storage chamber 1001 through the oil outlet 205. When the atomizing medium in the second oil storage chamber 1001 is less, the user tilts the electronic atomizing device, and the atomizing medium in the first oil storage chamber 2001 can be introduced into the second oil storage chamber 1001, so that the atomizing core 15 can be atomized to produce aerosol.

[0082] In this example, please continue to refer to Figure 3 , Figure 4 and Figure 5A fourth filling groove 102 is arranged on the periphery of the first connecting port 101, a first sealing member 23 is arranged on the periphery of the extension portion 206, and at least part of the side wall of the first sealing member 23 is arranged in the fourth filling groove 102. The first sealing member 23 is molded on the periphery of the first connecting port 101 and the second connecting port 201 by in-mold injection molding, so that the first sealing member 23 is fused to the fourth filling groove 102 and the periphery of the extension portion 206, so that the oil storage assembly 200 and the atomization assembly 100 are fused together, thereby sealing the connection position of the oil storage assembly 200 and the atomization assembly 100 to prevent leakage of the atomization medium.

[0083] More specifically, the atomizer assembly 100 is connected to the oil storage assembly 200, that is, the first connection port 101 and the second connection port 201 are embedded and connected, the assembled atomizer assembly 100 and the oil storage assembly 200 are implanted in the mold of the first sealing member 23, and molten plastic slurry is injected into the mold to obtain the first sealing member 23. The first sealing member 23 is molded around the connection position of the first connection port 101 and the second connection port 201 and the outer side of the extension portion 206, so that the first sealing member 23 is welded and sealed with the side wall of the extension portion 206 and the fourth filling groove 102 of the atomizer housing 10 to avoid leakage of the atomizing medium at the connection position between the sealed oil storage assembly 200 and the atomizer assembly 100; at the same time, since the atomizer assembly 100 and the oil storage assembly 200 are welded together by the first sealing member 23 formed by in-mold injection molding, the strength of the connection position thereof is increased to avoid circuit breakage and leakage of the atomizing medium during transportation.

[0084] Based on this, the present application also provides a forming method of an electronic atomization device, see Figure 8 , Figure 8 : is a flow chart of a molding method of an electronic atomization device provided in one embodiment of the present application.

The first sealing component 23 is molded around the connection position of the first connecting port 101 and the second connecting port 201 and the outer side of the extension part 206, so that the first sealing component 23 is welded and sealed with the side wall of the extension part 206 and the fourth filling groove 102 of the atomizer housing 10, thereby avoiding leakage of the atomization medium at the connection position of the sealed oil storage component 200 and the atomizer component 100.

[0103] Step S3: implant the integrated oil storage component 200 and atomization component 100 into the power supply storage cavity 3001 of the power supply component 300, and close and snap together to form an electronic atomization device.

[0104] Step S13: The forming method of the power supply assembly 300 is as follows:

[0105] Among them, the power supply component 300 includes a first PCB board 33, a battery 34, a connecting column 38 and a second PCB board 35.
