[0040] like Figure 1As shown, the present application proposes an atomizer 100, which can be applied to an electronic atomization device. The electronic atomization device generally includes the atomizer 100 and a power supply device. The atomizer 100 obtains the electric energy required for the operation of the atomizer 100 by being electrically connected to the power supply device. The specific shapes of the atomizer 100 are various. In the present embodiment, the atomizer 100 is in the shape of a long rod, and the electronic atomization device using the atomizer 100 can also be in the shape of a long rod; in other embodiments, the atomizer 100 can be in the shape of a cube, and the electronic atomization device using the atomizer 100 can be in the shape of a rectangular box. In the present application, the specific shapes of the atomizer 100 and the electronic atomization device using the atomizer 100 are not specifically limited.

[0041] Please refer to Figures 1 to 5 In the embodiment of the present application, the atomizer 100 includes a shell assembly 10 .

[0042] The shell assembly 10 is provided with a liquid storage chamber 13 and a mounting hole 123, and an elastic cleaning portion 1231 is provided between the mounting hole 123 and the liquid storage chamber 13. The elastic cleaning portion 1231 is configured such that when squeezed by an external force, at least a portion of the elastic cleaning portion 1231 can expand radially away from the center of the mounting hole 123 to open the mounting hole 123; when the external force is removed, the elastic cleaning portion 1231 contracts radially close to the center of the mounting hole 123 by its own elastic force to close the mounting hole 123.

[0043] According to the atomizer 100 of the embodiment of the present application, when the injection needle acts on the elastic cleaning portion 1231, the injection needle contacts a part of the elastic cleaning portion 1231, and the part of the elastic cleaning portion 1231 is fixed, so the part of the elastic cleaning portion 1231 is elastically deformed by the force of the injection needle, so that at least part of the elastic cleaning portion 1231 opens radially away from the center of the mounting hole 123 to flexibly open part of the mounting hole 123. The injection needle extends into the liquid storage chamber 13 through the mounting hole 123, and the injection needle injects atomized liquid into the liquid storage chamber 13. When the liquid storage chamber 13 stores a certain amount of atomized liquid, when the injection needle exits the liquid storage chamber 13 through the mounting hole 123, the elastic cleaning portion 1231 cleans the surrounding side of the injection needle under the action of elasticity, and when the injection needle exits the liquid storage chamber 13, the elastic cleaning portion 1231 flexibly closes under the action of elasticity to form a self-seal.

[0044] Through the above-mentioned technical scheme, the present application can use the injection needle to act on the elastic cleaning part 1231 to smoothly pass through the elastic cleaning part 1231 and enter the liquid storage chamber 13 to perform the injection operation. When the injection needle exits the liquid storage chamber 13 through the mounting hole 123, the elastic cleaning part 1231 can clean the injection needle so that the atomized liquid attached to the side of the injection needle can remain in the liquid storage chamber 13 to avoid being carried out of the liquid storage chamber 13 by the injection needle, thereby improving the accuracy of the injection needle in injecting the atomized liquid. After the injection needle exits the liquid storage chamber 13, the elastic cleaning part 1231 forms a self-seal to avoid leakage of the atomized liquid outside the liquid storage chamber 13.

[0045] In some embodiments, Figure 4 and Figure 5 As shown, the elastic cleaning portion 1231 includes at least two elastic protrusions, which are arranged in the hole wall of the mounting hole 123 close to one end of the liquid storage chamber 13, and a gap is formed between at least two elastic protrusions. When an external force acts, the elastic protrusion at least partially moves radially away from the gap.

[0046] With such arrangement, the injection needle can act on the gap between the elastic protrusions to enable the elastic cleaning portion 1231 to be movable and open. When the injection needle exits the liquid storage chamber 13 through the mounting hole 123, the elastic protrusion located on one side of the liquid storage chamber 13 can clean the surrounding side of the injection needle.

[0047] As an embodiment, the elastic cleaning portion 1231 includes two elastic protrusions, which are arranged oppositely on the peripheral wall of the mounting hole 123 so that the cleaning portion forms a straight-line gap, wherein the two elastic protrusions can be symmetrically arranged in the mounting hole 123. Such an arrangement is intended to improve the cleaning efficiency of the elastic cleaning portion 1231 and facilitate the elastic cleaning portion 1231 to be opened or closed movably.

[0048] In some specific embodiments, the elastic cleaning portion 1231 includes a plurality of elastic protrusions sequentially arranged along the circumference of the inner wall of the mounting hole 123 , and a gap is formed between two adjacent elastic protrusions along the circumference of the mounting hole 123 .

[0049] As an embodiment, the elastic cleaning portion 1231 includes four elastic protrusions, which are evenly spaced and arranged on the peripheral wall of the mounting hole 123, so that the cleaning portion forms a cross-shaped gap. This arrangement is intended to improve the cleaning efficiency of the elastic cleaning portion 1231 and facilitate the elastic cleaning portion 1231 to be opened or closed movably.

[0050] In other embodiments, the elastic cleaning portion 1231 includes eight elastic protrusions, which are evenly spaced and arranged on the peripheral wall of the mounting hole 123, so that the cleaning portion forms a cross-shaped gap. This arrangement is intended to improve the cleaning efficiency of the elastic cleaning portion 1231 and facilitate the elastic cleaning portion 1231 to be opened or closed movably.

[0051] It is understandable that the number of the elastic cleaning parts 1231 can be three, five, six or other numbers, and the present application does not make any specific limitation on this.

[0052] In some embodiments, the gap included in the elastic cleaning portion 1231 is a capillary gap. As an embodiment, the gap of the capillary gap can be 0 mm to 1 mm. In this way, when liquid flows through the capillary gap, the liquid molecules can form a liquid seal under the action of capillary force to prevent the liquid from leaking out of the capillary gap.

[0053] In some specific embodiments, Figure 6 and Figure 7 As shown, one of the adjacent elastic protrusions is provided with a first inclined surface 1232, and the other is provided with a second inclined surface 1233 opposite to and parallel to the first inclined surface 1232. The first inclined surface 1232 and the second inclined surface 1233 are both arranged at an inclined angle to the central axis of the mounting hole 123; a gap is formed between the first inclined surface 1232 and the second inclined surface 1233.

[0054] With such a configuration, under the action of the gravity of the liquid, the first bevel 1232 and the second bevel 1233 can fit together to prevent the liquid from flowing out of the gap between the first bevel 1232 and the second bevel 1233, so as to increase the sealing effect; in addition, the deformation ability of the elastic protrusion in the beveled portion can be increased, the contact area with the injection needle can be increased, and the scraping and cleaning effect can be improved.

[0055] In some embodiments, Figure 2 As shown, the atomizer 100 further includes an atomizer assembly 20 and an electrode needle 30 . The atomizer assembly 20 is disposed in the housing assembly 10 and is in liquid communication with the liquid storage chamber 13 . The electrode needle 30 is inserted into the mounting hole 123 and is electrically connected to the atomizer assembly 20 .

[0056] It can be understood that in some embodiments, the housing assembly 10 can be provided with two mounting holes 123 connected to the liquid storage chamber 13, and the number of electrode needles 30 is two. The two electrode needles 30 are respectively plugged into the corresponding mounting holes 123 after the injection needle injects liquid into the liquid storage chamber 13. Of course, in other embodiments, the housing assembly 10 can be provided with only one mounting hole 123 connected to the liquid storage chamber 13, and the number of electrode needles 30 is one. The specific shape of the mounting hole 123 is adapted to the electrode needle 30, so that the mounting hole 123 can be better blocked after the injection needle injects liquid into the liquid storage chamber 13.

[0057] With such a configuration, the mounting hole 123 can not only allow the injection needle to extend into or withdraw from the liquid storage chamber 13, but also allow the electrode needle 30 to be installed. In this way, the spatial layout of the atomizer 100 is optimized so that the atomizer 100 can be miniaturized.

[0058] Considering that when the electrode needle 30 is installed in the mounting hole 123, part of the gas in the mounting hole 123 may be squeezed by the electrode needle 30 from the mounting hole 123 into the liquid storage chamber 13, so that the air pressure in the liquid storage chamber 13 increases. Such an increase in air pressure will squeeze the atomized liquid in the liquid storage chamber 13, thereby causing the atomized liquid to penetrate into other parts or even leak to the outer surface of the shell assembly 10.

[0059] In some embodiments, Figures 1 to 4 As shown, the housing assembly 10 includes a liquid storage cup 11 and a base 12. The liquid storage cup 11 is provided with a liquid storage tank 111 and an air outlet channel 112 connected to the liquid storage tank 111. The base 12 is installed at the notch of the liquid storage tank 111 to cover the notch of the liquid storage tank 111 to form a liquid storage cavity 13. The base 12 is provided with an air inlet channel 124 and a mounting hole 123. The atomizer assembly 20 is arranged in the liquid storage cavity 13 and is respectively connected to the base 12 and the liquid storage cup 11. The atomizer assembly 20 has an atomizer channel 21 respectively connected to the air inlet channel 124 and the air outlet channel 112. The base 12 can be installed at the notch of the liquid storage tank 111 in a detachable or non-detachable connection.

[0060] With such a configuration, when the electrode needle 30 is installed in the mounting hole 123, the gas in the mounting hole 123 is discharged to the outside of the housing assembly 10 through the exhaust groove 1222, so as to prevent the air in the mounting hole 123 from being squeezed into the liquid storage chamber 13, thereby maintaining the air pressure balance in the liquid storage chamber 13, and further preventing the atomized liquid from leaking due to increased air pressure. At the same time, the mounting hole 123 is divided into sections, which is convenient for the processing of the exhaust groove 1222 and the assembly of the atomizer 100.

[0061] In other embodiments, the mounting hole 123 may be disposed on the liquid storage cup 11 and adjacent to the atomizer assembly 20 , so that the electrode needle 30 is electrically connected to the atomizer assembly 20 when inserted into the mounting hole 123 .

[0062] In some embodiments, Figures 2 to 5 As shown, the base 12 includes a bottom cover 121 and a sealing member 122, the bottom cover 121 is covered in the notch by the sealing member 122 and is sealed and connected to the atomizer assembly 20; the mounting hole 123 includes a first through hole 1211 arranged on the bottom cover 121 and a second through hole 1221 arranged on the sealing member 122 and connected to the first through hole 1211; the elastic cleaning portion 1231 is formed on the inner wall of one end of the second through hole 1221 close to the liquid storage chamber 13, and the second through hole 1221 is provided with an exhaust groove 1222 extending toward the first through hole 1211 on the hole wall of the elastic cleaning portion 1231 on the side away from the liquid storage chamber 13; the air inlet channel 124 is penetrated by the bottom cover 121 and the sealing member 122 and is connected to the exhaust groove 1222, and / or the exhaust groove 1222 is directly connected to the atmosphere.

[0063] With such a configuration, when the electrode needle 30 is installed in the mounting hole 123, the gas in the mounting hole 123 is discharged to the outside of the housing assembly 10 through the exhaust groove 1222, so as to prevent the air in the mounting hole 123 from being squeezed into the liquid storage chamber 13, thereby maintaining the air pressure balance in the liquid storage chamber 13, and further preventing the atomized liquid from leaking due to increased air pressure. At the same time, the mounting hole 123 is divided into sections, which is convenient for the processing of the exhaust groove 1222 and the assembly of the atomizer 100.

[0064] In some embodiments, Figures 2 to 5 As shown, a wire groove 1223 connected to the bottom of the exhaust groove 1222 is provided on the side of the seal 122 away from the liquid storage chamber 13. The wire groove 1223 and the bottom cover 121 together form an air permeable channel connected to the air inlet channel 124. The air inlet channel 124 includes an air permeable hole 1212 arranged on the bottom cover 121.

[0065] In this way, the wire groove 1223 can allow the lead of the atomizer assembly 20 to pass through, so that the lead of the atomizer assembly 20 can be set in the exhaust groove 1222. When the electrode needle 30 is inserted into the mounting hole 123, the electrode needle 30 contacts the lead in the exhaust groove 1222, thereby realizing the electrical connection between the electrode needle 30 and the atomizer assembly 20; at the same time, it avoids the lead of the atomizer assembly 20 being directly set in the mounting hole 123, resulting in a large liquid leakage gap between the outer surface of the electrode needle 30 and the inner wall of the mounting hole 123.

[0066] In addition, when the electrode needle 30 is inserted into the mounting hole 123, the gas in the mounting hole 123 flows through the exhaust groove 1222, the air passage, and the air hole 1212 in sequence under the squeezing action of the electrode needle 30, and is discharged to the outside of the shell assembly 10; thereby preventing the air in the mounting hole 123 from being squeezed into the liquid storage chamber 13, maintaining the air pressure balance in the liquid storage chamber 13, and further avoiding the problem of leakage of the atomized liquid due to increased air pressure.

[0067] In one embodiment, the exhaust groove 1222 extends from the second through hole 1221 to the inner wall of the first through hole 1211 and communicates with the atmosphere through the first passage.

[0068] In yet another embodiment, the aperture of the first through hole 1211 is larger than the aperture of the second through hole 1221 , and the exhaust groove 1222 is connected to the atmosphere through the gap between the first through hole 1211 and the electrode needle 30 .

[0069] In some embodiments, an isolation structure 31 is further provided between the portion of the electrode needle 30 in the mounting hole 123 and the elastic cleaning portion 1231. The isolation structure 31 is used to prevent the liquid leaking out of the liquid storage chamber 13 or adhering to the elastic cleaning portion 1231 from contacting the electrode needle 30, so as to avoid a chemical reaction between the electrode needle 30 and the liquid to produce reactants that contaminate the liquid in the liquid storage chamber 13.

[0070] In some embodiments, the isolation structure 31 includes a sealing gasket, wherein the sealing gasket can be made of a flexible material, such as silicone or rubber. The sealing gasket is separately arranged from the electrode needle 30 and can be installed in the first through hole 1211 of the mounting hole 123 in sequence with the electrode needle 30. A sealing gasket is further provided between the electrode needle 30 and the elastic cleaning portion 1231 to further enhance the sealing effect of the liquid storage chamber 13 and prevent the atomized liquid from penetrating through the elastic cleaning portion 1231 and contacting the electrode needle 30.

[0071] In other embodiments, Figure 2 As shown, the isolation structure 31 includes an electrode cap, which is installed at one end of the electrode needle 30 near the elastic cleaning portion 1231. The electrode cap can be installed at one end of the electrode needle 30 by a detachable connection method, such as: snap connection, threaded connection, etc., and the electrode cap can also be installed at one end of the electrode needle 30 by a non-detachable connection method, such as: bonding. Such a setting is intended to further enhance the sealing effect of the liquid storage chamber 13 and prevent the atomized liquid from penetrating the elastic cleaning portion 1231 and contacting the electrode needle 30.

[0072] In other embodiments, the isolation structure 31 includes a protective layer formed integrally on one end of the electrode needle 30 located in the mounting hole 123, and the protective layer can be made of a material coating that does not react with the atomized liquid, such as a dense ceramic glaze layer, a metal coating that does not contain or contains a trace amount of heavy metals, such as a titanium metal or its alloy coating, etc. This arrangement prevents the atomized liquid from penetrating the elastic cleaning portion 1231 and contacting the electrode needle 30.

[0073] In some embodiments, Figures 2 to 4 As shown, the seal 122 is detachably mounted on one side of the bottom cover 121 close to the liquid storage chamber 13. This arrangement is intended to facilitate the assembly and disassembly of the seal 122 and the bottom cover 121, thereby facilitating the cleaning or maintenance of the internal structure and internal components of the housing assembly 10.

[0074] In some embodiments, Figure 4 As shown, a plug-in portion is convexly provided on one side of the bottom cover 121 facing the sealing member 122, and a matching portion that is plugged and matched with the plug-in portion is provided on the sealing member 122. Such a configuration is intended to further facilitate the assembly and disassembly of the sealing member 122 and the bottom cover 121.

[0075] In some embodiments, Figures 2 to 5As shown, a sealing ring is provided on the peripheral side of the sealing member 122, and the sealing ring abuts against the peripheral wall of the liquid storage tank 111. Such a setting is intended to improve the sealing performance between the sealing member 122 and the liquid storage tank 111, thereby improving the sealing performance of the liquid storage chamber 13. Similarly, a sealing ring can also be provided at one end of the mounting hole 123 adjacent to the liquid storage chamber 13 to improve the sealing performance when the electrode cap of the electrode needle 30 is installed in the mounting hole 123, thereby improving the sealing performance of the liquid storage chamber 13.

[0076] The base 12 can be detachably mounted at the notch of the liquid storage tank 111, and the base 12 can be mounted at the notch of the liquid storage tank 111 by means of a snap connection, a threaded connection, a plug connection, etc. This arrangement is intended to facilitate the assembly and disassembly of the base 12 and the liquid storage cup 11, thereby facilitating the cleaning or maintenance of the internal structure and internal components of the housing assembly 10.

[0077] In some embodiments, a positioning protrusion is convexly provided on the peripheral side of the base 12, and a positioning groove cooperating with the positioning protrusion is concavely provided on the liquid storage cup 11.
