[0031] The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0032] Please refer to Figures 1 to 2 , Figure 1 which is an exploded view of an electronic atomization device provided by an embodiment of the present application; Figure 2 is Figure 1 a cross-sectional view of the atomizer body in the A-A direction in. In this embodiment, an electronic atomization device is provided for atomizing an atomization medium to form an aerosol. Among them, the atomization medium can be a liquid medicine formed by dispersing a certain medicine in a liquid solvent, an oil added with aroma components, or any other liquid suitable for atomization, such as e-liquid. The electronic atomization device can be used in the fields of beauty, medical treatment, e-cigarettes, etc. The electronic atomization device includes an atomizer body 10 and a power supply component 20.

[0033] As Figure 2 shown, the atomizer body 10 includes a housing assembly 1, an atomization core 2, and a liquid storage bottle 3. The housing assembly 1 encloses and forms a mouthpiece 11, and a first cavity 12 and a second cavity 13 that are interconnected and arranged in parallel. The user can inhale the aerosol through the mouthpiece 11. Alternatively, the mouthpiece 11 can also be a spray port to spray the aerosol to a preset position. The first cavity 12 and the second cavity 13 extend along the height direction Y of the atomizer body 10.

[0034] In one embodiment, referring to Figure 3 , Figure 3 is Figure 2 a schematic structural view of the atomizer body excluding the liquid storage bottle in; along the height direction Y of the atomizer body 10, the mouthpiece 11 is coaxially connected to the second cavity 13; the first cavity 12 and the second cavity 13 are arranged at intervals in a direction perpendicular to the height direction Y of the atomizer body 10, and one end (i.e., the bottom end) of the first cavity 12 facing the mouthpiece 11 is connected to the second cavity 13.

[0035] In a specific embodiment, combining Figure 3 and Figure 4 , Figure 4 is Figure 2Schematic structural diagram of the upper housing. The housing assembly 1 includes an upper housing 14 and a bottom cover 15; the upper housing 14 encloses and forms a suction nozzle 11, a first groove 141 and a second groove 142. The first groove 141 and the second groove 142 extend along the height direction Y of the atomizer body 10, and the openings of the first groove 141 and the second groove 142 both face the side away from the suction nozzle 11. The first groove 141 serves as the first cavity 12. The second groove 142 is located on one side of the suction nozzle 11 along the height direction Y of the atomizer body 10 and is communicated with the suction nozzle 11. The first groove 141 is arranged side by side with the second groove 142 in a direction perpendicular to the height direction Y of the atomizer body 10. The bottom cover 15 covers the port at one end of the second groove 142 away from the suction nozzle 11 and cooperates with the second groove 142 to form a second cavity 13.

[0036] In some embodiments, the housing assembly 1 further includes a first sealing seat 16, a second sealing seat 17 and a liquid absorbing cotton 18. The second sealing seat 17 is arranged on the bottom cover 15, and the surface of the second sealing seat 17 facing away from the bottom cover 15 has an insertion groove, and an air inlet hole is opened on the bottom wall of the insertion groove. A part of the atomization core 2 is embedded in the insertion groove to seal the bottom of the second cavity 13 through the second sealing seat 17 and supply air to the atomization core 2 through the air inlet hole to carry out the aerosol formed by atomization. The first sealing seat 16 is arranged at the connection between the atomization core 2 and the suction nozzle 11 for sealing the connection gap between the atomization core 2 and the suction nozzle 11. The liquid absorbing cotton 18 is arranged between the bottom cover 15 and the second sealing seat 17 for absorbing the atomization medium leaking from the air inlet hole and reducing the risk of liquid leakage. Among them, the first sealing seat 16 and the second sealing seat 17 can be elastomers such as plastics and silica gels.

[0037] In some embodiments, referring to Figure 4 , the upper housing 14 further has a communication cavity 143, and along a direction perpendicular to the height direction Y of the atomizer body 10, the communication cavity 143 extends from the side wall of the upper housing 14 to the inner wall surface of the second cavity 13; that is, the communication cavity 143 communicates with the second cavity 13. The bottom wall of the first cavity 12 is communicated with the communication cavity 143. When the liquid storage bottle 3 is connected to the first cavity 12, the bottle mouth of the liquid storage bottle 3 supplies liquid to the second cavity 13 through the communication cavity 143. In this embodiment, as Figure 3 shown, the electronic atomization device further includes a third sealing seat 4, and the third sealing seat 4 plugs the port at one end of the communication cavity 143 away from the second cavity 13 to prevent liquid leakage.

[0038] The atomization core 2 is arranged in the second cavity 13 for atomizing the atomization medium entering the second cavity 13. In one embodiment, referring to Figure 4, the atomization core 2 is spaced apart from at least a part of the inner wall surface of the second cavity 13 along its circumferential direction, and a liquid storage cavity 22 is defined and formed; the first cavity 12 communicates with the liquid storage cavity 22 to supply liquid to the atomization core 2. Specifically, the outer wall surfaces of the side walls of the atomization core 2 are all spaced apart from the inner wall surface of the second cavity 13 to increase the volume of the liquid storage cavity 22.

[0039] In a specific embodiment, the ratio of the cross-sectional area of the atomization core 2 to the cross-sectional area of the second cavity 13 is 0.5 - 0.7; for example, the ratio of the two can be 0.5, 0.55, 0.6, 0.65 or 0.7.

[0040] In the above solution, compared with the solution where the cross-sectional area of the second cavity 13 is much larger than the cross-sectional area of the atomization core 2, the volume of the liquid storage cavity 22 defined and formed by the atomization core 2 and the second cavity 13 can be within a preset range, reducing the risk that the atomization medium stays in the liquid storage cavity 22 for a long time and is repeatedly heated, resulting in the deterioration of the atomization medium or the generation of toxic substances.

[0041] In a specific embodiment, the atomization core 2 includes an outer tube 21, an inner tube, a liquid storage cotton 23, a liquid guiding cotton 24, a ventilation tube 25 and a heating element. The outer tube 21 has a liquid inlet, and the inner tube is sleeved inside the outer tube 21 and is spaced apart from the outer tube 21. The liquid storage cotton 23 is arranged between the outer tube 21 and the inner tube for storing liquid. The atomization medium in the second cavity 13 enters the liquid storage cotton 23 through the liquid inlet. The liquid guiding cotton 24 is arranged inside the inner tube for guiding liquid. The heating element is used to heat and atomize the atomization medium when powered on to form an aerosol. The aerosol flows out to the mouthpiece 11 through the ventilation tube 25.

[0042] The liquid storage bottle 3 is detachably connected to the side of the first cavity 12 facing away from the suction nozzle 11 and is used to supply liquid to the second cavity 13; and along the depth direction of the liquid storage bottle 3, at least half of the liquid storage bottle 3 protrudes from the housing assembly 1. In this way, during the process of assembling or disassembling the liquid storage bottle 3, a force can be applied to at least half of the liquid storage bottle 3 to increase the force, facilitating the assembly or disassembly of the liquid storage bottle 3; moreover, the liquid storage bottle 3 can be tightly assembled to the first cavity 12, reducing the risk of liquid leakage due to the loose connection between the liquid storage bottle 3 and the first cavity 12. For example, when the user holds the liquid storage bottle 3 for assembly or disassembly, the user's hand can hold most of the outer side surface of the liquid storage bottle 3, so as to facilitate the user to apply a greater force to the liquid storage bottle 3 for assembly or disassembly. And by arranging the first cavity 12 and the second cavity 13 side by side, connecting the liquid storage bottle 3 to the first cavity 12, and arranging the atomization core 2 in the second cavity 13, in this way, the atomization medium flowing out of the liquid storage bottle 3 will flow through the first cavity 12 and then enter the second cavity 13. Compared with the scheme of directly entering the second cavity 13 from the liquid storage bottle 3, it can buffer the flow rate, hydraulic pressure, etc. of the atomization medium flowing out of the liquid storage bottle 3, so as to reduce the risk of liquid leakage or the atomization medium being directly sucked into the user's mouth due to the atomization core 2 not atomizing these atomization media in time.

[0043] In a specific embodiment, along the depth direction of the liquid storage bottle 3, the ratio of the length of the part of the liquid storage bottle 3 protruding from the housing assembly 1 to the total length of the liquid storage bottle 3 is 0.6 - 0.8; for example, this ratio can be 0.6, 0.65, 0.7, 0.75 or 0.8.

[0044] In some embodiments, referring to Figure 3 , the first cavity 12 includes a first cavity part 121 and a second cavity part 122 that communicate with each other. One end of the first cavity part 121 facing away from the second cavity part 122 communicates with the communication cavity 143; the bottle mouth of the liquid storage bottle 3 passes through the second cavity part 122 from one end of the second cavity part 122 facing away from the first cavity part 121 and is embedded in the first cavity part 121 and connected to the first cavity part 121; wherein, the orthographic projection of the liquid storage bottle 3 on the upper housing 14 is located in the second cavity part 122; that is, the cross-sectional area of the liquid storage bottle 3 is smaller than the cross-sectional area of the second cavity part 122. In this way, during the process of installing the liquid storage bottle 3, the alignment of the liquid storage bottle 3 and the first cavity part 121 can be limited through the second cavity part 122, so as to facilitate the rapid insertion of the liquid storage bottle 3 into the first cavity part 121; at the same time, after the liquid storage bottle 3 is assembled with the first cavity part 121, the liquid storage bottle 3 can be positioned through the side wall of the second cavity part 122, reducing the risk of the connection between the liquid storage bottle 3 and the first cavity part 121 becoming loose due to the liquid storage bottle 3 shaking back and forth, resulting in liquid leakage.

[0045] In some embodiments, the liquid storage bottle 3 and the first cavity 12 may be threadedly connected. In a specific embodiment, an internal thread is provided in the first cavity 121, and an external thread is provided at the bottle mouth of the liquid storage bottle 3, and the internal thread and the external thread are screwed together to realize a detachable connection between the liquid storage bottle 3 and the first cavity 12. Of course, in other embodiments, the liquid storage bottle 3 and the first cavity 12 may also be connected by interference fit or plug-in connection.

[0046] In some embodiments, please refer back to Figure 2 The outer side of the bottle mouth of the liquid storage bottle 3 is also provided with a sealing groove; the sealing groove is arranged along the circumferential direction of the bottle mouth. The electronic atomization device also includes a bottle mouth sealing ring 5, which is embedded in the sealing ring and is used to seal the gap between the inner wall surface of the first cavity 121 and the bottle mouth.

[0047] In some embodiments, see Figure 5 and Figure 6 , Figure 5 for Figure 1 A cross-sectional view of the power supply assembly shown in the figure along the AA line; Figure 6 for Figure 1 The AA section view of the assembled electronic atomizer device is shown. The power supply assembly 20 is detachably connected to the atomizer body 10, and is used to supply power to the atomizer body 10. Specifically, the power supply assembly 20 and the atomizer body 10 can be detachably connected by magnetic attraction or snap connection.

[0048] The power supply assembly 20 has a receiving cavity 6 with an opening at one end, and the opening faces the atomizer body 10. After the liquid storage bottle 3 is connected to the first cavity 12, it is received in the receiving cavity 6 through the opening of the receiving cavity 6. In this way, after the atomizer body 10 is connected to the power supply assembly 20, the liquid storage bottle 3 is hidden inside the electronic atomization device, which prevents the liquid storage bottle 3 from being pierced by sharp objects and leaking during transportation or use, and also prevents children from being curious about the liquid in the liquid storage bottle 3 and accidentally using it.

[0049] In one embodiment, the power supply assembly 20 further includes a microphone base 7 and a microphone 8; the microphone base 7 is provided with an airflow hole 71; the microphone 8 is provided on the microphone base 7 and communicated with the airflow hole 71, and is used to sense the airflow entering from the airflow hole 71. The end surface of the air inlet end of the airflow hole 71 is an inclined surface 72. In this way, the risk of the atomized medium adhering to the inclined surface 72 and blocking the airflow hole 71, resulting in the failure of the microphone 8 to start, can be reduced.

[0050] Specifically, the microphone seat 7 has a protrusion on one side of the surface facing the atomizer body 10, and the protrusion has a through hole as an air flow hole 71. The microphone 8 is arranged on the side of the microphone seat 7 away from the atomizer body 10. The end surface of the protrusion away from the microphone 8 is an inclined surface 72.

[0051] Of course, in specific embodiments, the power supply component 20 further includes structures such as a housing and a battery. These structures are similar to the relevant structures of the existing power supply component 20.

[0052] In the electronic atomization device provided by the embodiment of the present application, by detachably connecting the liquid storage bottle 3 to the side of the first cavity 12 facing away from the mouthpiece 11, and along the depth direction of the liquid storage bottle 3, at least half of the liquid storage bottle 3 protrudes from the housing assembly 1; thus, during the process of assembling or disassembling the liquid storage bottle 3, a force can be applied to at least half of the liquid storage bottle 3 to increase the force, facilitating the assembly or disassembly of the liquid storage bottle 3; and the liquid storage bottle 3 can be tightly assembled to the first cavity 12, reducing the risk of liquid leakage due to the loose connection between the liquid storage bottle 3 and the first cavity 12. In addition, by arranging the first cavity 12 and the second cavity 13 side by side, connecting the liquid storage bottle 3 to the first cavity 12, and arranging the atomization core 2 in the second cavity 13, in this way, the atomization medium flowing out of the liquid storage bottle 3 will flow through the first cavity 12 and then enter the second cavity 13. Compared with the scheme of directly entering the second cavity 13 from the liquid storage bottle 3, it can buffer the flow rate, hydraulic pressure, etc. of the atomization medium flowing out of the liquid storage bottle 3, so as to reduce the risk of liquid leakage caused by the atomization core 2 not atomizing these atomization media in time or the atomization medium being directly sucked into the user's mouth.

[0053] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
