[0035] The present application provides an atomization device. The present application also provides an electronic atomization device including the atomization device.

[0036] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0037] like Figures 1 to 7 As shown, an embodiment of the present application provides an electronic atomization device, which includes a power supply device 2 and an atomization device 1, and the atomization device 1 is connected to the power supply device 2. Specifically, the atomization device 1 and the power supply device 2 can be connected in a non-detachable manner. It is understandable that the atomization device 1 and the power supply device 2 can also be connected in a detachable manner, and the embodiment of the present application does not impose any specific restrictions on this.

[0038] In some specific embodiments, the power supply device 2 includes a shell 21 and a power supply 22 arranged in the shell 21. The power supply 22 is used to provide working current to the atomization device 1. One end of the shell 21 has an installation cavity, and at least part of the atomization device 1 is located in the installation cavity.

[0039] In some specific embodiments, the atomizing device 1 mainly includes a nozzle 11, an oil cup 12, a sealing member 13 and an atomizing core 14. The nozzle 11 is provided with a accommodating chamber 114 and an air outlet chamber 115 that are interconnected. The accommodating chamber 114 is used to provide an accommodating space for the oil cup 12, and the air outlet chamber 115 is used to provide a space for the adsorbed atomized smoke. The oil cup 12 is connected to one end of the nozzle 11 where the accommodating chamber 114 is provided. The oil cup 12 is provided with an oil tank 123 and an air guide. The channel 121 is used to guide the atomized smoke to the air outlet cavity 115. The seal 13 is provided between the suction nozzle 11 and the oil cup 12 to isolate the oil tank 123 and the accommodating cavity 114 to prevent the atomized smoke from flowing back to the oil tank 123 through the accommodating cavity 114. The atomizer core 14 is in liquid communication with the oil tank 123. The liquid in the oil tank 123 is usually smoke oil. The atomizer core 14 is used to atomize the liquid in the oil tank 123 into smoke.

[0040] Among them, the atomizing device 1 also includes an extension portion 18 protruding from the sealing member 13 toward the air outlet cavity 115. The extension portion 18 has an outlet end 181 connecting the air guide channel 121 and the accommodating cavity 114. The mouthpiece 11 is provided with a blocking portion 111 on the side wall of the accommodating cavity 114 near the air outlet cavity 115. The blocking portion 111 is arranged on the outside of the outlet end 181 of the extension portion 18 to block the air flow flowing out of the outlet end 181 from flowing toward the accommodating cavity 114. In this way, when the atomizing device 1 is working, the user inhales through the mouthpiece 11, and the outside air enters the position of the atomizing core 14 of the atomizing device 1. At the same time, the atomizing core 14 atomizes the liquid in the oil tank 123 into smoke. The air flow carries the smoke through the air guide channel 121 and the extension portion 18 to the outlet end 181, and then carries the smoke into the air outlet cavity 115 to be inhaled into the mouth of the user. Here, by protruding the extension portion 18 from the sealing member 13, the smoke can be guided, thereby improving the efficiency of smoke inhalation by the user. In addition, by providing the above-mentioned blocking portion 111, the smoke entering the air outlet cavity 115 from the outlet end 181 can be blocked from flowing into the accommodating cavity 114, thereby reducing gas dispersion.

[0041] It should be noted that the blocking portion 111 is located at the periphery of the extension portion 18 at the outlet end, which means that the blocking portion 111 overlaps with the extension portion 18 in the direction of the outlet end, so that the blocking portion 111 can block at least part of the smoke flowing from the outlet end 181 to the air outlet cavity 115 in the air intake cavity 114, and the side of the sealing member 13 facing the air outlet cavity 115 is Figure 4 One side in the direction shown by the Z axis.

[0042] The atomizer device 1 of the above structure has an extension 18 provided on the side of the seal 13 facing the air outlet cavity 115, and the extension 18 protrudes from the seal 13. This can reduce the amount of smoke retained in the chamber enclosed between the mouthpiece 11 and the seal 13, thereby improving the user's ability to inhale smoke from the mouthpiece 11. In addition, the mouthpiece 11 has a blocking portion 111 provided on the inner wall of the accommodating cavity 114 near the air outlet cavity 115. The blocking portion 111 abuts the seal 13 and is located outside the outlet end 181 of the extension 18. This can block the airflow from the outlet end 181 from flowing into the accommodating cavity 114 and reduce smoke dispersion.

[0043] In some specific embodiments, the blocking portion 111 can be a sheet-like blocking wall structure protruding from the inner wall of the accommodating chamber 114, or it can be an annular blocking wall structure protruding from the inner wall of the accommodating chamber 114, that is, the annular blocking wall surrounds the extension portion 18 and is located at the outer periphery of the outlet end 181, as long as it can block at least part of the smoke flowing from the outlet end 181 to the air outlet chamber 115 from entering the accommodating chamber 114.

[0044] In some embodiments, a vent tube 17 is provided within the oil cup 12. An oil reservoir 123 is formed between the outer wall of the vent tube 17 and the inner wall of the oil cup 12. A seal 13 is provided within the open end of the oil reservoir facing the nozzle. The inner wall of the vent tube 17 defines an air guide channel 121. One end of the vent tube 17 protrudes from the side of the seal 13 facing the air outlet cavity 115 to form an extension 18. Specifically, the vent tube 17 is provided within the oil cup 12. The oil reservoir 123 is a groove-shaped structure provided within the oil cup 12. The vent tube 17 is used to guide the smoke generated by the heated and atomized atomizer core to the air outlet cavity 115 of the nozzle 11. One end of the vent tube 17 extends to the atomizing cavity, and the other end extends to the air outlet cavity 115 of the nozzle 11 to form the extension 18. This arrangement can make the layout of the oil cup 12 more compact and can more efficiently guide the smoke atomized by the atomizer core 14 to the air outlet cavity 115 of the nozzle 11.

[0045] In some embodiments, the extension portion 18 extends axially into the air outlet cavity 115, and a gap is formed between the blocking portion 111 and the outer peripheral wall of the extension portion 18, and the gap connects the air outlet cavity 115 and the accommodating cavity 114. During the operation of the atomizer device 1, the user inhales through the mouthpiece 11, and at the same time, the atomizer core 14 atomizes the tobacco oil in the oil tank 123 into smoke. External gas enters the interior of the atomizer device 1. When the gas flows through the area where the atomizer core 14 is located, it carries the smoke and is guided into the air outlet cavity 115 through the extension portion 18, and is then inhaled into the mouth of the user. However, in the above process, the smoke in the air outlet cavity 115 will inevitably condense. By forming a gap between the blocking portion 111 and the extension portion 18, the storage of the condensate is achieved through the gap, so that the condensate can be stored in the accommodating cavity 114.

[0046] Furthermore, the gap is a capillary gap, so that the condensate formed in the air outlet cavity is guided into the accommodating cavity 114 by capillary force.

[0047] In some embodiments, the blocking portion 111 is in sealing contact with the sealing member 13 to seal and isolate the air outlet cavity 115 from the accommodating cavity 114. The blocking portion 111 abuts against the sealing member 13 to isolate the air outlet cavity 115 from the accommodating cavity 114, preventing smoke directed toward the air outlet cavity 115 from flowing into the accommodating cavity 114 and preventing smoke loss. Furthermore, the smoke collection effect in the air outlet cavity 115 is enhanced, thereby improving the user experience of the atomizing device 1.

[0048] In some embodiments, the suction nozzle 11 further includes a positioning member 112, and the oil cup 12 is provided with a limiting member 122 adapted to the positioning member 112. When assembling the atomizing device 1, the suction nozzle 11 needs to be installed on the oil cup 12. By providing the positioning member 112 on the suction nozzle 11 and providing the limiting member 122 adapted to the positioning member 112 on the oil cup 12, the positioning member 112 and the limiting member 122 are ensured to be installed during the installation process. Then, the suction nozzle 11 and the oil cup 12 can be installed, thereby improving the convenience and efficiency of the installation of the suction nozzle 11 and preventing mistakes during the installation of the suction nozzle 11.

[0049] In this embodiment, an optional implementation is provided, in which the positioning member 112 is a positioning protrusion protruding from the wall surface of the suction nozzle 11 toward the oil cup 12, and the limiting member 122 is a limiting groove provided on the oil cup 12 to accommodate and adapt to the positioning protrusion. In this way, during the process of installing the suction nozzle 11 on the oil cup 12, the suction nozzle 11 is easily inserted into the oil cup 12, thereby improving the installation efficiency.

[0050] In this embodiment, another optional implementation is also provided, in which the positioning member 112 is a first magnetic member arranged on the inner wall surface of the suction nozzle 11, and the limiting member 122 is a second magnetic member arranged on the outer wall surface of the oil cup 12, and the first magnetic member is magnetically connected to the second magnetic member. During the installation of the suction nozzle 11 and the oil cup 12, the installation between the suction nozzle 11 and the oil cup 12 is achieved through the above-mentioned magnetic connection, which can improve the convenience of the connection and limitation between the positioning member 112 and the limiting member 122, thereby improving the installation efficiency of the suction nozzle 11 and the oil cup 12.

[0051] In this embodiment, another optional implementation is also provided, in which the positioning member 112 is a clip provided on the inner wall surface of the suction nozzle 11, and the limiting member 122 is a clamping member provided on the outer wall surface of the oil cup 12, and the clip and the clamping member are detachably clamped. During the installation of the suction nozzle 11 and the oil cup 12, the installation between the suction nozzle 11 and the oil cup 12 is achieved through the connection of the above-mentioned clip and the clamping member, which can also improve the convenience of the connection and limitation of the positioning member 112 and the limiting member 122, thereby improving the installation efficiency of the suction nozzle 11 and the oil cup 12.

[0052] In some specific embodiments, the positioning member 112 is a positioning protrusion provided in the accommodating cavity 114, the limiting member 122 is a limiting groove, and the cross-sectional area of ​​the limiting groove gradually decreases from the side close to the suction nozzle 11 to the side away from the suction nozzle 11. Specifically, the positioning member 112 is set as a positioning protrusion and the limiting member 122 is set as a limiting groove adapted to the positioning protrusion. In this way, the positioning between the suction nozzle 11 and the oil cup 12 can be achieved through a simple structure, which has a simple structure and significant effect. Here, by setting the above-mentioned limiting groove as a groove with a gradually decreasing cross-sectional area, the installation efficiency of the positioning protrusion in the limiting groove can be improved. The positioning protrusion can be quickly installed in the limiting groove along the gradually decreasing direction, so as to improve the installation efficiency and have a fool-proof effect.

[0053] Moreover, through the above arrangement, when the suction nozzle 11 and the oil cup 12 are installed together, the positioning protrusion and the limiting groove can also solve the problem that the suction nozzle 11 is easy to rotate, thereby preventing the suction nozzle 11 from rotating relative to the oil cup 12 after installation.

[0054] It should be noted that the number of limiting protrusions and positioning grooves provided is not limited here. One or more limiting protrusions and positioning grooves may be provided. The only requirement is that the number of limiting protrusions and positioning grooves provided is the same. When multiple limiting protrusions and positioning grooves are provided, the multiple limiting protrusions are arranged along the circumference of the suction nozzle 11, and correspondingly, the multiple positioning grooves are arranged along the circumference of the oil cup 12.

[0055] Furthermore, in some embodiments, in order to increase the abutment area between the positioning protrusion and the limiting groove, so as to improve the installation stability between the suction nozzle 11 and the oil cup 12, on the basis of the above embodiments, the cross-sectional area of ​​the positioning protrusion is set to gradually decrease from the side away from the oil cup 12 to the side close to the oil cup 12. In this way, while improving the installation efficiency of the positioning protrusion in the limiting groove, the abutment area between the positioning protrusion and the limiting groove can be increased, thereby improving the stability of the above connection.

[0056] In addition, the limiting member 122 can also be a limiting groove set on the suction nozzle 11, and correspondingly, the positioning member 112 is a positioning protrusion set on the oil cup 12 and adapted to the limiting groove. In this way, the installation efficiency of the suction nozzle 11 and the oil cup 12 can be improved and the suction nozzle 11 can be prevented from rotating relative to the oil cup 12.

[0057] In some embodiments, the nozzle 11 is further provided with a protrusion 113 protruding toward the center of the nozzle 11 within the accommodating cavity 114, and the seal 13 is provided with a recessed portion 131 that avoids the protrusion 113 to reduce the volume of the chamber enclosed between the nozzle 11 and the seal 13, thereby reducing the volume of the chamber enclosed between the nozzle 11 and the seal 13, thereby reducing the volume of the smoke retained in the chamber enclosed between the nozzle 11 and the seal 13, and further reducing the convergence of smoke in the chamber, thereby improving the user experience.

[0058] It should be noted that the number of protrusions 113 and recesses 131 provided is not limited here; one or more protrusions 113 and recesses 131 may be provided; the only requirement is that the number of protrusions 113 and recesses 131 be the same. When multiple positioning protrusions 113 and recesses 131 are provided, the multiple protrusions 113 are arranged along the circumference of the suction nozzle 11, and correspondingly, the multiple positioning protrusions 113 are arranged along the circumference of the oil cup 12.

[0059] In some embodiments, the oil cup 12 is provided with a plurality of oil reservoirs 123 independently arranged around the periphery of the air guide channel 121; the atomizer device 1 includes a plurality of atomizer cores 14 arranged one-on-one with the oil reservoirs 123 and in liquid communication. Specifically, the provision of multiple oil reservoirs 123 can ensure the supply of tobacco oil when the atomizer device 1 atomizes tobacco oil. By providing multiple oil reservoirs 123 and atomizer cores 14 arranged one-on-one with each of them, the atomization efficiency of the tobacco oil in the oil reservoir 123 can be improved, thereby improving the atomization capacity of the atomizer device 1. In addition, a groove for mounting the atomizer core 14 is provided on the oil reservoir 123. Here, the atomizer core 14 is provided as a porous ceramic structure so that the tobacco oil in the oil reservoir 123 can penetrate into the atomizer core 14 through the porous capillary structure of the ceramic, and the atomizer core 14 heats the tobacco oil that penetrates from the oil reservoir 123.

[0060] In some embodiments, the atomizer device 1 further includes a sealing sleeve 15 for sealing the multiple atomizer cores 14. It should be noted that the number of sealing sleeves 15 provided is not limited herein; one or more sealing sleeves 15 may be provided. In other words, one sealing sleeve 15 may seal multiple atomizer cores 14, or one sealing sleeve 15 may seal a single atomizer core 14. When the sealing sleeve 15 is configured to seal one of the multiple atomizer cores 14, this can improve the ease of assembly of the sealing sleeve 15 with the multiple atomizer cores 14, enhance installation efficiency, facilitate subsequent maintenance and replacement of the sealing sleeve 15, and enhance the airtightness after installation.

[0061] In some embodiments, the atomizer 1 includes a base 16 disposed at the other end of the oil cup 12 away from the suction nozzle 11, and an atomizer chamber connected to the air guide channel 121 is formed between the base 16, the oil cup 12 and the atomizer core 14. Specifically, the atomizer core 14 heats the tobacco oil guided from the oil tank 123 to the atomizer core 14 into smoke to form smoke in the atomizer chamber. In this way, when the user inhales through the suction nozzle 11, external gas enters the atomizer chamber of the atomizer 1. The gas passes through the atomizer chamber and carries the atomized smoke through the vent pipe 17 to guide the atomized smoke into the user's mouth to complete an atomization cycle. By setting up the atomizer chamber, when multiple atomizer cores 14 atomize the tobacco oil in multiple oil tanks 123, it is convenient for the atomized smoke to gather, and it is more convenient for the air guide channel 121 to guide the smoke to the suction nozzle 11, thereby improving the user's inhalation efficiency of the smoke.

[0062] In some embodiments, the protrusion of the air guide channel 121 from the seal 13 in the axial direction of the atomizer 1 is greater than or equal to 3 mm. Ensuring that the protrusion of the air guide channel 121 from the seal 13 is within this range can better guide the smoke atomized by the oil tank 123 and the atomizer core 14, further preventing smoke dispersion and improving the smoke concentration effect.

[0063] Exemplarily, the size of the air guide channel 121 protruding from the seal 13 can be 3 mm, 3.2 mm, 3.5 mm, 4 mm, 5 mm, 6 mm, 8 mm, 10 mm, 15 mm, 20 mm, etc.

[0064] It should be noted that the axial direction of the atomizing device 1 refers to Figure 2 The direction shown by the Z axis.
