DETAILED DESCRIPTION

It needs to be understood that these orientation terms are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0040] An embodiment of the present application provides an electronic atomization device, please refer to Figure 1 and Figure 2 , the electronic atomization device comprises a shell assembly 10, a sealing assembly 20 and a driving assembly 30.

[0041] The shell assembly 10 has a liquid storage space 10a and a mist outlet 10b, and the mist outlet 10b is located on one side of the liquid storage space 10a.

[0042] The sealing assembly 20 is located on the side of the liquid storage space 10a away from the mist outlet 10b, and the sealing assembly 20 has a through hole 20a.

[0043] At least part of the driving assembly 30 is located on the side of the sealing assembly 20 away from the liquid storage space 10a, and the driving assembly 30 comprises a telescopic rod 31, which is telescopically arranged in the through hole 20a. Along the circumference of the telescopic rod 31, the hole wall of the through hole 20a is in interference fit with the telescopic rod 31, and the telescopic rod 31 can be in and out of the liquid storage space 10a by telescoping.

[0044] Specifically, the liquid storage space 10a of the shell assembly 10 is used to store atomization liquid, and it needs to be noted that in some embodiments, the atomization liquid can be directly poured into the liquid storage space 10a, that is, the atomization liquid can be in contact with the wall of the liquid storage space 10a. Of course, in other embodiments, the liquid storage space 10a can also be used to install a liquid storage assembly 40 containing atomization liquid, such as a cassette bottle containing atomization liquid, thereby achieving the purpose of storing atomization liquid.

[0045] Exemplarily, please refer to Figure 8 , the liquid storage space 10a is used to install the liquid storage assembly 40, and the liquid storage assembly 40 has a liquid storage cavity 40a for storing atomization liquid, one end of the liquid storage cavity 40a is in communication with the mist outlet 10b, and the other end of the liquid storage cavity 40a is provided with a pushing piece 50, the telescopic rod 31 is connected with the pushing piece 50, and the telescopic rod 31 drives the pushing piece 50 to move by telescoping, so as to drive the atomization liquid in the liquid storage cavity 40a to move towards the side of the mist outlet 10b.

[0046] Specifically, the liquid storage assembly 40 can be part of the electronic atomization device, or it can be an independent structure matched with the electronic atomization device.

[0047] The atomized liquid is stored in the liquid storage cavity 40a. The liquid storage cavity 40a is in communication with the mist outlet 10b at one end close to the mist outlet 10b, and has an opening at the other end. The push piece 50 is arranged at the opening and can block the opening to reduce the risk of leakage of the atomized liquid from the opening.

[0048] The push piece 50 is movably arranged in the liquid storage cavity 40a, so that under the pushing action of the telescopic rod 31, the push piece 50 can move towards the side of the mist outlet 10b to push the atomized liquid to flow towards the mist outlet 10b.

[0049] The specific material of the push piece 50 is not limited, for example, the push piece 50 is a silica gel plug.

[0050] It can be understood that when the telescopic rod 31 is retracted, the telescopic rod 31 can also pull the push piece 50 to retract, i.e. move away from the side of the mist outlet 10b.

[0051] The electronic atomization device of the embodiment can be any type of atomization device. The atomized liquid includes but is not limited to medicinal liquid, nutrient liquid, beauty liquid, essence liquid, essence cream, disinfectant, insecticide, pesticide, etc., so that the electronic atomization device using the atomized liquid can be applied in different fields, such as medical field, beauty field, agricultural field, etc. For example, the electronic atomization device is a scalp atomization device, and the atomized liquid stored in the electronic atomization device is medicinal liquid. For another example, the electronic atomization device is an electronic cigarette, and the atomized liquid stored in the electronic atomization device is tobacco tar.

[0052] The mist outlet 10b of the shell assembly 10 is in communication with the liquid storage space 10a and can allow the atomized liquid to flow out.

[0053] The sealing assembly 20 is a sealing structure with sealing effect, which is arranged on the side opposite to the mist outlet 10b of the liquid storage space 10a.

[0054] The specific material of the sealing assembly 20 is not limited, for example, the sealing assembly 20 is waterproof silica gel.

[0055] The driving assembly 30 is a driving structure with driving force. The telescopic rod 31 of the driving assembly 30 can be telescoped relative to the liquid storage space 10a under the driving force of the driving assembly 30 itself, so as to realize the purpose of entering and exiting the liquid storage space 10a.

[0056] The telescopic rod 31 is telescoped relative to the liquid storage space 10a to push the atomized liquid in the liquid storage space 10a to move towards the mist outlet 10b.

[0057] Exemplarily, the electronic atomization device has an air passage in communication with the mist outlet 10b, which is used to communicate with a gas supply assembly (such as an air compressor) of the electronic atomization device or an external gas supply assembly. Under the gas supply of the gas supply assembly, a high-speed airflow can be formed in the air passage. The driving assembly 30 is telescopic through the driving telescopic rod 31 to push the atomized liquid to move towards the mist outlet 10b. When the high-speed airflow mixes with the atomized liquid, the atomized liquid can be cut at high speed to disperse into tiny droplets and flow out of the mist outlet 10b, thereby realizing the atomization process.

[0058] The driving assembly 30 can be only partially located on the side of the sealing assembly 20 away from the liquid storage space 10a, or all regions thereof can be located on the side of the sealing assembly 20 away from the liquid storage space 10a.

[0059] The through hole 20a is used for the telescopic rod 31 to pass through, and the hole wall at the through hole 20a is in interference fit with the telescopic rod 31. That is, the elasticity of the hole wall of the through hole 20a of the sealing assembly 20 is used to make the through hole 20a expand and deform to be sleeved on the telescopic rod 31, so that the hole wall of the through hole 20a continuously pre-presses the telescopic rod 31, thereby making the two closely adhere to each other, further reducing the risk of the atomized liquid passing through the through hole 20a, and achieving a better pre-pressing waterproof effect.

[0060] In the related art, the telescopic rod 31 of the driving assembly 30 is a movable part, which is used to push the piston in the card bottle body to move. The telescopic rod 31 is prone to local atomized liquid leakage, which makes the atomized liquid easily enter the product, and the product is prone to damage due to water entering.

[0061] The shell assembly 10 of the electronic atomization device has a liquid storage space 10a and a mist outlet 10b, and the mist outlet 10b is located on one side of the liquid storage space 10a. The sealing assembly 20 is located on the side of the liquid storage space 10a away from the mist outlet 10b, and the sealing assembly 20 has a through hole 20a. At least part of the driving assembly 30 is located on the side of the sealing assembly 20 away from the liquid storage space 10a, and the driving assembly 30 includes a telescopic rod 31 which is telescopically arranged in the through hole 20a. Along the circumference of the telescopic rod 31, the hole wall of the through hole 20a is in interference fit with the telescopic rod 31, and the telescopic rod 31 can be telescopically in and out of the liquid storage space 10a. Thus, the hole wall of the through hole 20a can pre-press the telescopic rod 31 through the interference fit with the telescopic rod 31 to achieve pre-pressing waterproof, which can reduce the risk of the atomized liquid leaking out of the liquid storage space 10a and continuing to leak through the through hole 20a along the telescopic rod 31, thereby improving the anti-leakage effect of the electronic atomization device and reducing the risk of damage to the internal structure of the electronic atomization device product caused by local leakage of the atomized liquid.

[0062] In an embodiment, please refer to Figure 5 and Figure 11The hole wall of the through hole 20a has a pre-pressing part in interference fit with the telescopic rod 31, and the pre-pressing part extends along the circumference of the telescopic rod 31 to form an annular sealing structure. In this way, the sealing effect of the sealing assembly 20 at the through hole 20a can be further improved.

[0063] In an embodiment, the hole wall of the through hole 20a has a pre-pressing part in interference fit with the telescopic rod 31, and the vertical dimension of the pre-pressing part gradually decreases towards the telescopic rod 31 in the vertical section of the pre-pressing part. In this way, the anti-leakage effect can be better while reducing the influence on the axial movement of the telescopic rod 31.

[0064] It should be noted that the vertical section shape of the pre-pressing part is not limited, such as a triangular or arc shape.

[0065] In an embodiment, referring to Figure 7 The liquid storage space 10a is open on the side close to the sealing assembly 20 to form a communication port 10c, and the housing assembly 10 includes an end wall 11 with the communication port 10c. The part of the sealing assembly 20 close to the end wall 11 protrudes to form an enclosed section 22 in contact with the outer end surface of the end wall 11, and the enclosed section 22 extends around the circumference of the communication port 10c to form a sealing cavity 22a. In this way, the installation stability of the sealing assembly 20 can be improved, and the risk of shaking of the sealing assembly 20 can be reduced.

[0066] Specifically, the communication port 10c of the liquid storage space 10a is used for the telescopic rod 31 to enter and exit the liquid storage space 10a. Depending on the specific structure of the electronic atomization device, the specific mode of the telescopic rod 31 entering and exiting the liquid storage space 10a is different.

[0067] For example, the liquid storage space 10a is used to install a liquid storage assembly 40, and part of the liquid storage assembly 40 extends to the outside of the liquid storage space 10a through the communication port 10c. The telescopic rod 31 extends into the liquid storage cavity 40a by pushing the pushing piece 50, and thus also extends into the liquid storage space 10a.

[0068] For another example, the liquid storage space 10a is used to install a liquid storage assembly 40, and the liquid storage assembly 40 is located in the communication port 10c. The telescopic rod 31 directly passes through the communication port 10c to extend into the liquid storage space 10a, and then connects with the pushing piece 50.

[0069] The sealing assembly 20 protrudes to form an enclosed section 22 towards the side of the end wall 11 with the communication port 10c, thereby abutting against the end wall 11 of the housing assembly 10. When the telescopic rod 31 of the drive assembly 30 is telescoped, the end wall 11 of the housing assembly 10 can limit the movement of the sealing assembly 20 towards the side of the mist outlet 10b, thereby improving the installation stability of the sealing assembly 20.

[0070] The enclosing section 22 is an annular structure extending around the circumference of the communication opening 10c, which can enclose a sealed cavity 22a, thereby reducing the risk of the leaked atomized liquid flowing out of the side of the sealing assembly 20.

[0071] It should be noted that in some embodiments, the enclosing section 22 is only in contact with the outer end surface of the end wall 11.

[0072] In other embodiments, the enclosing section 22 is in interference fit with the outer end surface of the end wall 11. In this way, a closed loop between the sealing assembly 20 and the end wall 11 of the shell assembly 10 can be achieved, which can further improve the installation stability of the sealing assembly 20, and also can strengthen the sealing and waterproof effect of the sealing assembly 20.

[0073] In an embodiment, referring to Figure 7 , the electronic atomization device includes an air inlet pipe 60 arranged in the shell assembly 10 and in communication with the mist outlet 10b at one end, and the sealing assembly 20 has a connecting hole 20b located on one side of the sealed cavity 22a in the radial direction, and the air inlet pipe 60 is arranged in the connecting hole 20b, and the hole wall of the connecting hole 20b is in interference fit with the air inlet pipe 60. In this way, the pre-pressure at the sealed cavity 22a and the through hole 20a can be increased, and the sealing and waterproof effect of the sealing assembly 20 can be further improved.

[0074] In fact, the air inlet pipe 60 of the electronic atomization device is used to communicate with the air supply assembly, and an air channel is formed in the air inlet pipe 60 for the high-speed airflow from the air supply assembly to flow to the mist outlet 10b, thereby atomizing the atomized liquid.

[0075] The sealing assembly 20 is formed with a connecting hole 20b for the air inlet pipe 60 to pass through, and since the connecting hole 20b is located on one side of the sealed cavity 22a in the radial direction, the hole wall of the connecting hole 20b is in interference fit with the air inlet pipe 60, which can form a pre-pressure on the hole wall of the connecting hole 20b, and the reaction force of the air inlet pipe 60 can also act on the sealing assembly 20, thereby increasing the pre-pressure at the sealed cavity 22a and the through hole 20a.

[0076] In an embodiment, referring to Figure 7 , the shell assembly 10 includes a shell body 12 and a middle shell 13 having a receiving cavity 13a, the shell body 12 has a liquid storage space 10a and a mist outlet 10b, and the middle shell 13 is located on the side of the liquid storage space 10a away from the mist outlet 10b, at least part of the sealing assembly 20 is located in the receiving cavity 13a, and along the radial direction of the telescopic rod 31, the sealing assembly 20 has an outer side wall 21 located on the side of the telescopic rod 31 away from the connecting hole 20b, and the outer side wall 21 is in interference fit with the cavity wall of the receiving cavity 13a. In this way, the pre-pressure at the sealed cavity 22a and the through hole 20a can be further increased, and the sealing and waterproof effect of the sealing assembly 20 can be further improved.

[0077] Specifically, the middle casing 13 is located in the casing body 12, which is used to accommodate the sealing assembly 20. The sealing assembly 20 can be partially located in the accommodating cavity 13a, or can be entirely located in the accommodating cavity 13a.

[0078] On the side of the sealing assembly 20 away from the connecting hole 20b in the radial direction, the outer side wall 21 of the sealing assembly 20 is in interference fit with the cavity wall of the accommodating cavity 13a, and the side of the sealing assembly 20 in the radial direction can be in interference fit with the air inlet pipe 60, and the other side in the radial direction can be in interference fit with the cavity wall of the accommodating cavity 13a. Thus, through the cooperation of the two, the annular pre-pressure in the middle position can be ensured, and the waterproof sealing effect can be further improved.

[0079] In an embodiment, referring to Figure 3 and Figure 4 , the casing assembly 10 includes the casing body 12 and the middle casing 13 with the accommodating cavity 13a, the casing body 12 includes the first sub-casing 121 and the second sub-casing 122, the first sub-casing 121 has the liquid storage space 10a and the mist outlet 10b, the middle casing 13 is located on the side of the liquid storage space 10a away from the mist outlet 10b, and at least part of the sealing assembly 20 is located in the accommodating cavity 13a.

[0080] Referring to Figure 10 , the outer end wall 11 of the first sub-casing 121 away from the mist outlet 10b extends to the outer circumferential side of the middle casing 13, on one side in the radial direction of the middle casing 13, the outer end wall 11 of the first sub-casing 121 is fastened and connected with the outer circumferential surface of the middle casing 13 by fasteners, and on the other side in the radial direction of the middle casing 13, part of the outer circumferential surface of the middle casing 13 is recessed to form a first glue groove 13b for bonding with the outer end wall 11 of the first sub-casing 121. Thus, the problem of easy gap and looseness between the first sub-casing 121 and the middle casing 13 can be solved, and the purpose of simultaneous fastening in the longitudinal and transverse directions can be achieved.

[0081] Specifically, the second sub-casing 122 is located on the side of the first sub-casing 121 away from the mist outlet 10b. The first sub-casing 121 and the second sub-casing 122 are connected with the middle casing 13 respectively.
