Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0031] In one embodiment, such as Figures 1 to 3 As shown in the illustration, this application also provides an electronic atomizing device 1, which specifically includes a housing assembly 100, a liquid outlet pipe 200 with an electric liquid pump 210, a liquid return pipe 300, and an atomizing component 400. The housing assembly 100 mainly houses an airflow channel 11, a liquid storage cotton 12, and a liquid storage chamber 13. The liquid storage cotton 12 surrounds the air inlet end of the airflow channel 11. The peripheral wall of the liquid storage chamber 13 has a liquid outlet (not shown) and a liquid return port (not shown). One end of the liquid outlet pipe 200 is connected to the liquid outlet, and the other end is in liquid communication with the liquid storage cotton 12. One end of the liquid return pipe 300 is connected to the liquid return port, and the other end is in liquid communication with the liquid storage cotton 12, so that when the liquid level in the liquid storage cotton 12 exceeds a preset threshold, excess liquid is recovered to the liquid storage chamber 13. The atomizing component 400 is mainly installed at the air inlet end of the airflow channel 11 and is in liquid communication with the liquid storage cotton 12. It is used to heat and atomize the liquid flowing from the liquid storage cotton 12 to form an aerosol.

[0032] It can be understood that the electronic atomization device 1 of the embodiment of the present application can be used to store a specific liquid (which can be an atomization liquid such as tobacco tar) through the liquid storage cavity 13 and the liquid storage cotton 12, and in the use process, the liquid storage cotton 12 guides the liquid to the atomization assembly 400, so that the atomization assembly 400 converts the specific liquid into an aerosol, and then the aerosol is sprayed outwards through the airflow channel 11 for the user to smoke. The liquid storage cotton 12 mentioned above is generally a special organic cotton, which has good liquid absorption and liquid guiding properties, and can effectively absorb the liquid in the liquid storage cavity 13 and ensure the atomization effect. In addition, bamboo charcoal cotton or other materials can also be used as a substitute to enhance the smoking taste of the electronic atomizer and reduce the odor. The other end of the liquid outlet pipeline 200 in liquid communication with the liquid storage cotton 12 specifically means that the other end of the liquid outlet pipeline 200 is provided with a corresponding liquid outlet, and the liquid storage cotton 12 at least partially covers the liquid outlet, so that the liquid flowing out of the liquid outlet of the liquid outlet pipeline 200 can directly flow into the liquid storage cotton 12. The other end of the liquid return pipeline 300 in liquid communication with the liquid storage cotton 12 specifically means that the other end of the liquid return pipeline 300 is provided with a corresponding liquid inlet, and the liquid storage cotton 12 at least partially covers the liquid inlet, so that when the liquid in the liquid storage cotton 12 is greater than a preset threshold (which is generally the maximum liquid storage capacity of the liquid storage cotton 12), the excess liquid in the liquid storage cotton 12 can flow into the liquid return pipeline 300 through the liquid inlet, and then the liquid return pipeline 300 returns the liquid to the liquid storage cavity 13. The atomization assembly 400 mentioned above is mainly arranged at the air inlet end of the airflow channel 11 and in liquid communication with the liquid storage cotton 12, which specifically means that the air inlet end of the airflow channel 11 is provided with a liquid guiding opening, and the liquid storage cotton 12 on the side of the airflow channel 11 can abut against the atomization assembly 400 through the liquid guiding opening, so that when there is liquid in the liquid storage cotton 12, the liquid can flow from the liquid storage cotton 12 to the atomization assembly 400 through the liquid guiding opening.

[0033] In addition, since the liquid outlet pipeline 200 of the embodiment of the present application is provided with the electric liquid pumping pump 210 to pump the liquid, the liquid outlet of the liquid storage cavity 13 can be arranged at any position on the peripheral wall of the liquid storage cavity 13, which will not affect the liquid outlet effect of the liquid storage cavity 13.

[0034] In this way, the electronic atomization device 1 provided by the embodiment of the present application adds the liquid return pipeline 300 between the liquid storage cotton 12 and the liquid storage cavity 13, so that when the liquid in the liquid storage cotton 12 is greater than the preset threshold, the excess liquid can be returned to the liquid storage cavity 13, that is, when the liquid in the liquid storage cavity 13 flows into the liquid storage cotton 12 too much, the excess liquid can be actively returned to the liquid storage cavity 13 through the liquid return pipeline 300, thereby avoiding the related oil leakage problem, and greatly improving the user experience.

[0035] In some examples, as Figure 1 andFigure 2 As shown, the liquid storage cotton 12 includes a first side surface (not labeled in the figure) and a second side surface (not labeled in the figure), which are oppositely arranged in the extension direction of the airflow passage 11. The other end of the liquid outlet pipeline 200 is in liquid communication with the liquid storage cotton 12 through the first side surface, and the other end of the liquid return pipeline 300 is in liquid communication with the liquid storage cotton 12 through the second side surface. In this way, through the above structural arrangement, the position of the liquid storage cotton 12 in liquid communication with the liquid return pipeline 300 is away from the position of the liquid storage cotton 12 in liquid communication with the liquid outlet pipeline 200 in the extension direction of the airflow passage 11, so that the liquid outlet pipeline 200 can better make the liquid come to the position of the liquid storage cotton 12 in liquid communication with the liquid return pipeline 300 only after the liquid fills the entire liquid storage cotton 12, thereby ensuring that the excess liquid in the liquid storage cotton 12 is returned to the storage cavity 13 through the liquid return pipeline 300 only when the liquid in the liquid storage cotton 12 is greater than the preset threshold (i.e., the maximum liquid storage capacity of the liquid storage cotton 12). Further, the second side surface is closer to the airflow outlet of the airflow passage 11 than the first side surface in the extension direction of the airflow passage 11. In this way, through the above structural arrangement, the second side surface of the electronic atomization device 1 will be above the first side surface when the user uses it for suction, and the effect of gravity can further ensure that the liquid in the liquid storage cotton 12 comes to the position of the liquid storage cotton 12 in liquid communication with the liquid return pipeline 300 only after the liquid outlet pipeline 200 fills the entire liquid storage cotton 12, thereby ensuring that the excess liquid in the liquid storage cotton 12 is returned to the storage cavity 13 through the liquid return pipeline 300 only when the liquid in the liquid storage cotton 12 is greater than the preset threshold (i.e., the maximum liquid storage capacity of the liquid storage cotton 12).

[0036] In some examples, as shown in Figure 1 and Figure 2 the liquid return port and the liquid outlet port are arranged at intervals in the extension direction of the airflow passage 11, and the liquid return port is closer to the airflow outlet of the airflow passage 11 than the liquid outlet port in the extension direction of the airflow passage 11. In this way, the position of the liquid return port of the electronic atomization device 1 will be higher than the position of the liquid outlet port when the user uses it for suction, so as to ensure the liquid return effect of the liquid return pipeline 300 under the influence of gravity.

[0037] It can be understood that the specific shape of the liquid return port and the liquid outlet port mentioned in the present example is not limited, including but not limited to a round port structure or a square port structure.

[0038] In some examples, as shown in Figure 1 and Figure 2As shown, the liquid return pipeline 300 is arranged to extend in a direction perpendicular to the extending direction of the airflow passage 11, and the peripheral wall of the liquid return pipeline 300 abuts against the second side surface, so that the liquid inlet of the liquid return pipeline 300 is at least partially sunk into the liquid storage cotton 12. In this way, by the above arrangement, when the liquid in the liquid storage cotton 12 is greater than the preset threshold value (i.e. the maximum liquid storage capacity of the liquid storage cotton 12), the excess liquid in the liquid storage cotton 12 is effectively recovered into the liquid storage cavity 13 due to the abutting and extruding of the liquid return pipeline against the second side surface of the liquid storage cotton 12.

[0039] In some examples, as shown in Figures 1 to 3 As shown, the shell assembly 100 includes a first shell 110 and a base 120, the base 120 is arranged at one end of the first shell 110 and forms a first mounting cavity 14 with the first shell 110, and the airflow passage 11 and the liquid storage cotton 12 are arranged in the first mounting cavity 14, respectively. In this way, by arranging the first shell 110 and the base 120, the arrangement positions of the airflow passage 11 and the liquid storage cotton 12 can be reasonably distributed, and at the same time, the airflow passage 11 and the liquid storage cotton 12 are protected by the first mounting cavity 14. Further, the shell assembly 100 further includes a second shell 130 having a liquid storage cavity 13, and the second shell 130 is tightly connected with the first shell 110. In this way, the liquid storage cavity 13 formed by the independent second shell 130 can maximize the liquid storage capacity of the liquid storage cavity 13.

[0040] It can be understood that the second shell 130 in the present example is arranged to extend along the extending direction of the airflow passage 11 to maximize the liquid storage capacity of the liquid storage cavity 13 as much as possible.

[0041] In some examples, as shown in Figures 1 to 3 As shown, the peripheral side wall of the air inlet end of the airflow passage 11 is provided with at least one liquid guide opening (not shown), and the atomization assembly 400 blocks all the liquid guide openings, so that the atomization assembly 400 is in liquid communication with the liquid storage cotton 12. In this way, by the above arrangement, the atomization assembly 400 can be better arranged in liquid communication with the liquid storage cotton 12. Further, the peripheral side wall of the air inlet end of the airflow passage 11 is provided with two liquid guide openings, and the two liquid guide openings are oppositely arranged along the radial direction of the airflow passage 11. In this way, by the above arrangement, the liquid in the liquid storage cotton 12 can be more uniformly penetrated into the entire atomization assembly 400, so as to improve the atomization effect of the atomization assembly 400. Further, the atomization assembly 400 includes a liquid guide cotton and a heating body, the liquid guide cotton blocks all the liquid guide openings, and the heating body is arranged on the liquid guide cotton. In this way, by the above arrangement, the liquid in the liquid guide cotton can be converted into aerosol by the heating work of the heating body, so as to be sprayed for the user to smoke.

[0042] It can be understood that the liquid guiding cotton in the example can be made of the same material as the liquid storage cotton 12 to ensure that it can effectively absorb the liquid in the liquid storage cotton 12 and ensure the atomization effect. The number of liquid guiding openings in the example can be increased or decreased as needed, including but not limited to the two mentioned above. The shape of the liquid guiding opening in the example can be rectangular, circular, or other shapes. The heating body in the example can be a heating sheet or a heating wire.

[0043] In some examples, as shown in Figures 1 to 3 The electronic atomization device 1 also includes a power supply assembly 500 electrically connected to the atomization assembly 400 and the electric liquid pump 210. In this way, through the above structure, when the power supply assembly 500 is powered on, it can on the one hand supply power to the electric liquid pump 210 through the power supply assembly 500, so that the liquid in the liquid storage cotton 12 is pumped into the liquid storage cotton 12. On the other hand, the power supply assembly 500 can supply power to the heating body of the atomization assembly 400, so that the heating body of the atomization assembly 400 is heated under the power supply of the power supply assembly 500. The liquid in the liquid guiding cotton is converted into aerosol and sprayed out for the user to inhale.

[0044] It can be understood that the power supply assembly 500 in the example can include a control mainboard, a control switch, a battery, and a charging interface. The control mainboard and the power supply assembly 500 are installed in the shell assembly 100. The control switch and the charging interface are exposed on the surface of the shell assembly 100 for easy switching control and charging operation.

[0045] In some examples, as shown in Figure 1 and Figure 3 One end of the second shell 130 is tightly connected to the peripheral side of the first shell 110 to form a reverse L-shaped groove. The shell assembly 100 also includes a third shell 140 surrounding the reverse L-shaped groove to form a second mounting cavity 15 for installing the power supply assembly 500. In this way, through the above structure, the second mounting cavity 15 can be better formed independently of the first mounting cavity 14 and the liquid storage cavity 13 to better independently install the power supply assembly 500, ensuring that the power supply assembly 500 is away from the liquid in these cavities to improve the service life of the power supply assembly 500.

[0046] It can be understood that the electric liquid pump 210 mentioned above can also be arranged in the second installation cavity 15 in the present example. The inverted L-shaped groove in the present example refers to the gap formed by the part of the second housing 130 and the part of the first housing 110, and the third housing 140 surrounding the inverted L-shaped groove refers to the third housing 140 surrounding the part of the gap to cooperate with the part of the second housing 130 and the part of the first housing 110 to form a complete cuboid second installation cavity 15.

[0047] In some examples, as shown in Figure 1 and Figure 3 , the third housing 140 and the edge of the inverted L-shaped groove are detachably fastened. In this way, through the above structure, the third housing 140 can be detached at any time according to actual installation and maintenance needs, so as to open the second installation cavity 15 and facilitate the installation, maintenance and replacement of the power supply assembly 500 (generally specifically referring to the battery).

[0048] It can be understood that the detachable fastening in the present example includes but is not limited to the buckle structure 16, that is, the third housing 140 and the edge of the inverted L-shaped groove can be detachably fastened through the buckle structure 16.

[0049] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields based on the inventive concept of the present application and the content of the specification and drawings are included in the patent protection scope of the present application.
