[0003] The atomizer and electronic atomization device provided in the present application are intended to solve the problem that the aerosol formed by atomization of the existing atomizer has a poor taste and a bad user experience.

[0004] In order to solve the above technical problems, a technical solution adopted in the present application is: to provide an atomizer, which includes a shell assembly, an atomizer core and a liquid storage bottle, the shell assembly encloses a suction nozzle, and a first cavity and a second cavity that are interconnected and arranged in parallel; the first cavity and the second cavity extend along the height direction of the atomizer; the atomizer core is arranged in the second cavity, and cooperates with the second cavity to form a liquid storage cavity; the liquid storage bottle is detachably connected to a side of the first cavity away from the suction nozzle, and the atomized medium in the liquid storage bottle can flow to the second cavity in a restrictive manner.

[0005] In one embodiment of the present application, the shell assembly is also surrounded by a connecting cavity, the first end of which extends to the inner wall surface of the second cavity and is connected to the second cavity; the bottom wall of the first cavity is connected to the connecting cavity to connect to the second cavity through the connecting cavity.

[0006] In one embodiment of the present application, along a direction perpendicular to the height direction of the atomizer, the communication cavity extends from the side wall of the housing assembly to the inner wall surface of the second cavity;

[0007] The atomizer further comprises a third sealing seat, and the third sealing seat blocks a port of the communicating cavity at one end away from the second cavity.

[0008] In one embodiment of the present application, along the height direction of the atomizer, a surface of one side of the communicating cavity close to the first cavity is provided with a plurality of liquid storage tanks arranged at intervals.

[0009] In one embodiment of the present application, a surface of one side of the communicating cavity close to the first cavity is a plane, and the plane is perpendicular to the height direction of the atomizer.

[0010] In an embodiment of the present application, along the height direction of the atomizer, the depth of the second cavity is greater than that of the first cavity.

[0011] In an embodiment of the present application, the maximum cross-section of the second cavity along the thickness direction of the atomizer is a sectional plane; the orthographic projection of the first end of the communication cavity on the sectional plane is located within the sectional plane, and along the thickness direction of the atomizer, the orthographic projection of the first end of the communication cavity on the sectional plane is spaced from both side edges of the sectional plane; the thickness direction of the atomizer is perpendicular to the height direction of the atomizer and the juxtaposed direction of the first cavity and the second cavity respectively.

[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 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 drug in a liquid solvent, an oil added with fragrance components, or any other liquid suitable for atomization, such as e-liquid. The electronic atomization device can be used in fields such as beauty, medical treatment, and e-cigarettes. The electronic atomization device includes an atomizer 10 and a power supply assembly 20.

[0033] As Figure 2 shown, the atomizer 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 mutually connected 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 10.

[0034] In one embodiment, referring to Figure 3 , Figure 3 is Figure 2 a schematic structural view of the atomizer in except for the liquid storage bottle; along the height direction Y of the atomizer 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 10, and one end (i.e., the bottom wall) of the first cavity 12 facing the mouthpiece 11 can be connected to the second cavity 13.

[0035] In a specific embodiment, in combination with 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 to form 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 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 10 and communicates 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 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 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] The atomization core 2 is arranged in the second cavity 13 for atomizing the atomization medium entering the second cavity 13. In one embodiment, see 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 defines a liquid storage cavity 22; 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.

[0038] 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.

[0039] In the above solution, compared with the solution in which 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 by the atomization core 2 and the second cavity 13 can be within a preset range, reducing the risk that due to the large volume of the liquid storage cavity 22, 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.

[0040] 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. The inner tube is sleeved inside the outer tube 21 and is spaced 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 nozzle 11 through the ventilation tube 25.

[0041] The liquid storage bottle 3 is detachably connected to one side of the first cavity 12 away from the nozzle 11 for supplying liquid to the second cavity 13; and the atomization medium in the liquid storage bottle 3 can flow restrictedly to the second cavity 13. Wherein, by detachably connecting the liquid storage bottle 3 to one side of the first cavity 12 away from the nozzle 11 and arranging the mutually connected first cavity 12 and second cavity 13 side by side; thus, when the atomizer 10 does not need liquid supply, the atomizer 10 can be placed upright (i.e., the nozzle 11 is upward) so that more atomization medium is stored in the liquid storage bottle 3; and when liquid supply is needed, the atomizer 10 is inverted (i.e., the nozzle 11 is vertically downward or inclined downward) so that the atomization medium in the liquid storage bottle 3 flows out and flows into the second cavity 13 through the first cavity 12, so as to minimize the number of times the atomization medium is repeatedly heated and make the aerosol formed by atomization have a better suction taste. In addition, by arranging the mutually connected first cavity 12 and 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, this scheme can buffer the flow rate, hydraulic pressure, etc. of the atomization medium flowing out of the liquid storage bottle 3, weaken the impact of too much atomization medium on the second cavity 13, or reduce the leakage caused by the atomization core 2 not atomizing these atomization media in time because the second cavity 13 stores too much atomization medium, or the atomization medium is directly sucked into the user's mouth, affecting the suction taste.

[0042] In some embodiments, in combination with Figure 3 , the housing assembly 1 also encloses and forms a communication cavity 143. The first end M of the communication cavity 143 extends to the inner wall surface of the second cavity 13 and communicates with the second cavity 13; the bottom wall of the first cavity 12 (i.e., the bottom wall of the first groove body 141) communicates with the communication cavity 143 to communicate with the second cavity 13 through the communication cavity 143. It can be understood that 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.

[0043] In the above solution, when the liquid storage bottle 3 supplies liquid (such as being inverted), on the one hand, most of the atomization medium flowing out of the liquid storage bottle 3 can flow into the communication cavity 143 through the bottom wall of the first cavity 12. Compared with the solution where the side wall of the first cavity 12 is communicated with the communication cavity 143, the risk that part of the atomization medium flowing out of the liquid storage bottle 3 is stored in the first cavity 12 and cannot enter the second cavity 13 is reduced, thereby effectively improving the utilization rate of the atomization medium. On the other hand, the atomization medium flowing out of the liquid storage bottle 3 will flow through the communication cavity 143 and then enter the second cavity 13. In this way, the communication cavity 143 can play a certain buffering role in the flow rate, hydraulic pressure, etc. of the atomization medium flowing out of the liquid storage bottle 3, weakening the impact of too much atomization medium on the second cavity 13, or reducing the risk of liquid leakage caused by the second cavity 13 storing too much atomization medium, resulting in the atomization core 2 not atomizing these atomization media in time, or the atomization medium being directly sucked into the user's mouth, affecting the suction taste.

[0044] In a specific embodiment, as Figure 4 , the communication cavity 143 is specifically formed on the upper housing 14.

[0045] In an embodiment, referring to Figure 4 , along a direction perpendicular to the height direction Y of the atomizer 10, the communication cavity 143 extends from the side wall of the upper housing 14 of the housing assembly 1 to the inner wall surface of the second cavity 13. In this embodiment, as Figure 3 shown, the atomizer 10 further includes a third sealing seat 4, and the third sealing seat 4 plugs the port at one end of the communication cavity 143 facing away from the second cavity 13 to prevent liquid leakage.

[0046] In an embodiment, referring to Figure 5 , Figure 5 is Figure 1 the B-B cross-sectional view of the atomizer shown. Along the height direction Y of the atomizer 10, a plurality of liquid storage grooves 144 are provided at intervals on the surface of the communication cavity 143 close to the first cavity 12. In this way, these liquid storage grooves 144 can also be used for liquid storage, thereby increasing the liquid storage volume to reduce the risk of dry burning of the atomization core 2.

[0047] In some embodiments, as Figure 5 shown, the surface of the communication cavity 143 close to the first cavity 12 is a plane, and the plane is perpendicular to the height direction Y of the atomizer 10. The liquid storage grooves 144 are specifically provided on this plane, and a plurality of liquid storage grooves 144 are provided at intervals along the flow direction of the atomization medium. This solution facilitates the storage of the atomization medium in the liquid storage grooves 144.

[0048] In the above embodiments, the upper housing 14 may include a top and a bottom that are detachably connected and oppositely arranged along the height direction Y of the atomizer 10. The mouthpiece 11 is formed at the top of the upper housing 14, the first cavity 12 is formed at the bottom of the upper housing 14, and a part of the second cavity 13 may be formed at the top of the upper housing 14, and the remaining part is formed at the bottom of the upper housing 14. Among them, the surface of one side of the top of the upper housing 14 facing the bottom cooperates with the surface of one side of the bottom facing the top to form a communication cavity 143. Specifically, a groove may be opened only on the surface of one side of the bottom of the upper housing 14 facing the top, and then cooperate with the surface of one side of the top facing the bottom to form the communication cavity 143; or a groove may be opened only on the surface of one side of the top of the upper housing 14 facing the bottom, and then cooperate with the surface of one side of the bottom facing the top to form the communication cavity 143; or, a groove is formed on the surfaces of the top and the bottom respectively, and the two grooves cooperate to form the communication cavity 143. Among them, when a groove is formed on the surface of the bottom of the upper housing 14, the liquid storage tank 144 is specifically opened on the inner surface of the bottom wall of the groove. When a groove is opened only on the top of the upper housing 14, the liquid storage tank 144 is specifically opened on the surface of one side of the bottom of the upper housing 14 facing the top.

[0049] In the above solution, by making the upper housing 14 include a detachable top and bottom, it is convenient to open the liquid storage tank 144 in the communication cavity 143. In this embodiment, the communication cavity 143 may not extend to the outer wall surface of the side wall of the upper housing 14, and the third sealing seat 4 cannot be provided either.

[0050] In some embodiments, as Figure 3 shown, along the height direction Y of the atomizer 10, the depth H1 of the second cavity 13 is greater than the depth H2 of the first cavity 12. In this way, when the atomizer 10 is inverted and the liquid storage bottle 3 supplies liquid, it can be ensured that there is always a part of the atomization medium in the second cavity 13, thereby reducing the risk of dry burning of the atomization core 2.

[0051] In one embodiment, referring to Figure 6 and Figure 7 , Figure 6 is a schematic diagram of the position of the upper housing when the atomizer provided in an embodiment of the present application is placed flat; Figure 7 is Figure 6Schematic diagram of the position of the positive projection of the first end of the connected cavity on the cross-section of the cross-section object. The maximum cross-section of the second cavity 13 along the thickness direction Z of the atomizer 10 is the cross-section N; the positive projection of the first end M of the connected cavity 143 on the cross-section N is located within the cross-section N, and along the thickness direction Z of the atomizer 10, the positive projection of the first end M of the connected cavity 143 on the cross-section N is spaced from both sides of the cross-section N. That is, along the thickness direction Z of the atomizer 10, the positive projection of the first end M of the connected cavity 143 on the cross-section N has a first distance L1 from the first side of the cross-section N; the positive projection of the first end M of the connected cavity 143 on the cross-section N has a second distance L2 from the second side of the cross-section N; wherein, L1 and L2 may be equal or unequal.

[0052] The thickness direction Z of the atomizer 10 is perpendicular to the height direction Y of the atomizer 10 and the juxtaposed direction of the first cavity 12 and the second cavity 13 respectively.

[0053] In the above solution, when the atomizer 10 is placed flat, that is, when the height direction Y of the atomizer 10 is parallel or nearly parallel to the bearing table, the atomizing medium in the second cavity 13 will not all flow back into the connected cavity 143, that is, a part of the atomizing medium will always remain in the second cavity 13 to prevent dry burning.

[0054] In some embodiments, see Figure 3 , the first cavity 12 includes a first cavity portion 121 and a second cavity portion 122 that are interconnected. One end of the first cavity portion 121 facing away from the second cavity portion 122 is connected to the connected cavity 143; the mouth of the liquid storage bottle 3 passes through the second cavity portion 122 from one end of the second cavity portion 122 facing away from the first cavity portion 121 and is embedded in the first cavity portion 121 and connected to the first cavity portion 121; wherein, along the height direction Y of the atomizer 10, the positive projection of the liquid storage bottle 3 on the housing assembly 1 is located within the second cavity portion 122; that is, the cross-sectional area of the liquid storage bottle 3 is smaller than the cross-sectional area of the second cavity portion 122. In this way, during the installation of the liquid storage bottle 3, the alignment of the liquid storage bottle 3 and the first cavity portion 121 can be limited by the second cavity portion 122 to facilitate the quick insertion of the liquid storage bottle 3 into the first cavity portion 121; at the same time, after the liquid storage bottle 3 and the first cavity portion 121 are assembled, the liquid storage bottle 3 can be positioned by the side wall of the second cavity portion 122 to reduce the risk of loosening of the connection between the liquid storage bottle 3 and the first cavity portion 121 due to the back-and-forth shaking of the liquid storage bottle 3, resulting in liquid leakage.

[0055] 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 portion 121, and an external thread is provided at the mouth of the liquid storage bottle 3. The internal thread and the external thread are screwed together to achieve the 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.

[0056] 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 atomizer 10 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.

[0057] In some embodiments, see Figure 8 and Figure 9 , Figure 8 for Figure 1 A cross-sectional view of the power supply assembly shown in the figure along the AA line; Figure 9 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 10 for supplying power to the atomizer 10. Specifically, the power supply assembly 20 and the atomizer 10 can be detachably connected by magnetic attraction or snap connection.

[0058] In one embodiment, part of the liquid storage bottle 3 of the atomizer 10 may protrude from the shell assembly 1. The power supply assembly 20 has a receiving chamber 6 with an opening at one end, and the opening of the receiving chamber 6 faces the atomizer 10. After the liquid storage bottle 3 is connected to the first cavity 12, the part of the liquid storage bottle 3 protruding from the shell assembly 1 is received in the receiving chamber 6 through the opening of the receiving chamber 6. In this way, after the atomizer 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 causing leakage during transportation or use, and also prevents children from being curious about the liquid in the liquid storage bottle 3 and using it by mistake.

[0059] Of course, in other embodiments, the liquid storage bottle 3 of the atomizer 10 may not protrude from the housing assembly 1 .

[0060] 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.

[0061] Specifically, the microphone base 7 has a protrusion on one side facing the atomizer 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 base 7 away from the atomizer 10. The end surface of the protrusion away from the microphone 8 is an inclined surface 72.

[0062] Of course, in a specific embodiment, the power supply assembly 20 further includes structures such as a housing and a battery, etc. These structures are similar to the related structures of the existing power supply assembly 20 .

[0063] The atomizer 10 provided by the embodiment of the present application detachably connects the liquid storage bottle 3 to the side of the first cavity 12 away from the mouthpiece, and arranges the mutually connected first cavity 12 and second cavity 13 side by side; in this way, when the atomizer 10 does not need to supply liquid, the atomizer 10 can be placed upright to store more atomization medium in the liquid storage bottle 3; when liquid supply is required, the atomizer 10 is inverted, so that the atomization medium in the liquid storage bottle 3 flows out and flows into the second cavity 13 through the first cavity 12, so as to minimize the number of times the atomization medium is repeatedly heated, and make the aerosol formed by atomization maintain a good suction taste. In addition, by arranging the mutually connected first cavity 12 and 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, this scheme can buffer the flow rate, hydraulic pressure, etc. of the atomization medium flowing out of the liquid storage bottle 3, weaken the impact of too much atomization medium on the second cavity 13, or reduce the leakage caused by the atomization core 2 not atomizing these atomization media in time due to too much atomization medium stored in the second cavity 13, or the atomization medium being directly sucked into the user's mouth, affecting the suction taste.

[0064] The above are only the implementation manners 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.
