Referring to fig. 1, fig. 1 is an exploded view of a part of a structure of an electronic atomization device according to an embodiment of the utility model. An electronic atomization device 10 according to an embodiment of the present utility model includes an atomization assembly, a liquid storage structure 200, and a seal assembly 100. The reservoir structure 200 is provided with an oil bin 210, and an atomized medium is stored in the oil bin 210. The liquid storage structure 200 is capable of providing nebulizable media to a nebulizing assembly, which is capable of nebulizing nebulizable media into aerosols for inhalation by a user. The seal assembly 100 is used to close or open the sump 210. When the electronic atomizing device 10 is aspirated or received, the seal assembly 100 closes the sump 210 to prevent leakage of the nebulizable medium within the sump 210. When the nebulizable medium in the sump 210 is less or depleted, the sump 210 can be opened by the seal assembly 100 and the nebulizable medium can be injected into the sump 210.

Referring to fig. 2, in one embodiment, the seal assembly 100 includes a holder 1100 and a shield 1200. The shutter 1200 is provided with a first communication port 1221. The shield 1200 is slidably disposed on the housing and has an open position and a closed position. When the shutter 1200 is in the open position, the first communication port 1221 communicates with the sump 210. The shutter 1200 is used to close the sump 210 when in the closed position.

With the seal assembly 100 described above, the shutter 1200 is capable of sliding relative to the housing 1100 between the open and closed positions, as the shutter 1200 is slidably disposed on the housing 1100. In the open position, nebulizable medium can be injected into the sump 210 via the first communication port 1221. When the nebulizable medium does not need to be injected into the oil sump 210, the shielding piece 1200 can be made to slide to the closed position, and at this time, the shielding piece 1200 can reset the oil sump 210, so that the nebulizable medium in the oil sump 210 is prevented from leaking, the use safety is ensured, and the electronic nebulizing device 10 realizes the child lock function. The shutter is shown in the closed position in fig. 4 and in the open position in fig. 5.

Further, the shutter 1200 is provided with a first communication port 1221, and an inner wall of the first communication port 1221 may be used as a force application point for driving the shutter 1200 to move. For example, an nebulizable medium may be injected into the sump 210 via the filler pipe 20. When the shutter 1200 closes the oil reservoir 210, the filler pipe 20 may extend into the first communication port 1221 and push against the inner wall of the first communication port 1221, thereby driving the shutter 1200 to slide to an open position relative to the frame 1100, allowing the filler pipe 20 to communicate with the oil reservoir 210. That is, the seal assembly 100 is provided with the first communication port 1221 on the shutter 1200, so that the seal assembly can not only communicate with the oil reservoir 210, but also serve as a portion for driving the shutter 1200 to slide, and thus, there is no need to provide a structure such as a handle or a button for pushing the shutter 1200 to move. In addition, the oil filler pipe 20 can simultaneously drive the shielding member 1200 to slide and realize the oil filler, so that a user does not need to directly contact the shielding member 1200, and the cleaning in the oil filler process can be ensured.

Further, the seal assembly 100 can open the oil sump 210 in a sliding manner, so as to prevent the nebulizable medium attached to the shielding member 1200 from splashing and overflowing in the oil sump 210. It should be noted that, in the conventional art, the oil sump 210 is opened by a flip or the like, so that the nebulizable medium is easy to overflow and splash. It will be appreciated that there will inevitably be some amount of nebulizable medium attached to the seal cap or its periphery within the sump 210, so that the nebulizable medium attached and the surrounding nebulizable medium will spill over as the flip is flipped over when the flip is opened. By sliding open, the shutter 1200 does not flip open and does not cause splash. When the shutter 1200 closes the oil chamber 210, the first communication port 1221 does not communicate with the oil chamber 210, and the nebulizable medium in the oil chamber 210 does not adhere to the inner wall of the first communication port 1221, so that overflow and splashing can be avoided.

Of course, in some embodiments, structures such as handles or buttons may be provided on the shade 1200 to push the shade 1200 to move, as desired.

In one embodiment, the shield 1200 is capable of being reset from an open position and maintained in a closed position. Because of the resettable function of the shielding element 1200, when the shielding element 1200 is not actively controlled to open the oil sump 210, the shielding element 1200 can keep the oil sump 210 closed, so that leakage during shaking and storage of the electronic atomizing device 10 is avoided, and safety problems caused by mistakenly eating an atomized medium by children are avoided. In other words, such an arrangement can have a child lock function.

Referring to fig. 2, in one embodiment, the seal assembly 100 further includes a reset element 130. The reset element 130 is resiliently coupled between the frame 1100 and the shutter 1200 to reset the shutter 1200 from the open position to the closed position. In this manner, when the movement of the shutter 1200 is not actively controlled, the shutter 1200 can be returned to or held in the closed position by the reset member 130 to keep the sump 210 closed, avoiding leakage of nebulizable media.

The reset element 130 is stretched and deformed when the shutter 1200 is actively pushed to slide, that is, when the oil reservoir 210 needs to be opened, the shutter 1200 can be pushed to integrally move through the inner wall of the first communication port 1221, and the reset element 130 is stretched and deformed along with the movement of the shutter 1200. When the shutter 1200 is no longer controlled to move or remain in a certain position, the reset member 130 can pull the shutter 1200 back to the closed position by its own elastic restoring force to effect the reset of the shutter 1200.

Of course, referring to fig. 2 and 3, the reset element 130 may be configured to deform under compression when the shutter 1200 is actively pushed to slide. Specifically, the reset element 130 may have one end abutting against the shutter 1200 and the other end abutting against the bracket 1100. The reset element 130 is compressively deformed by the sliding movement of the shutter 1200. When the shutter 1200 is no longer controlled to move or remain in a certain position, the reset member 130 can push the shutter 1200 back to the closed position by its own elastic restoring force to effect the reset of the shutter 1200.

With continued reference to fig. 2 and 3, in one embodiment, the bracket 1100 is provided with a mounting slot 1121, a portion of the structure of the shielding member 1200 is movably disposed in the mounting slot 1121, and the resetting member 130 elastically abuts against the shielding member 1200 and the slot wall of the mounting slot 1121. In this way, the elastic abutment action of the reset element 130 can make the shutter 1200 elastically limit. And since the shield 1200 is partially structured in the mounting groove 1121, the pushing movement of the reset member 130 to push the shield 1200 can be limited by the groove wall of the mounting groove 1121, so that the shield 1200 can move in a desired stroke.

Referring to fig. 2 in combination with fig. 4 and 5, in one embodiment, the shield 1200 includes an abutment 1210 and a baffle 1220. The abutment 1210 is located in the mounting groove 1121. One end of the restoring member 130 abuts against the abutting portion 1210, and the other end of the restoring member 130 abuts against the groove wall of the mounting groove 1121. The abutment 1210 extends along a reference plane that intersects the sliding direction of the shield 1200. The sliding direction is seen by arrow K in fig. 2 to 5. Since the reference surface intersects the sliding direction of the shutter 1200, the abutment portion 1210 can better abut against the reset member 130 and transmit motion when distributed along the reference surface, so that the reset member 130 can more accurately push the shutter 1200 to slide in the sliding direction.

The reference plane body may be perpendicular to the sliding direction of the shield 1200.

In some embodiments, the reset member 130 may be a spring. The abutment portion 1210 may further have a limiting post (not shown) penetrating into the reset element 130, so as to stabilize the position of the end of the reset element 130 abutting against the abutment portion 1210. Alternatively, the limiting post may be connected to the bottom wall of the mounting slot 1121 and penetrate through the restoring member 130, so that the radial position of the restoring member 130 is stable, and the middle portion of the restoring member 130 is not twisted or deflected.

Referring to fig. 2, in one embodiment, two limiting plates 1121a are disposed in the mounting slot 1121, and two limiting plates 1121a are surrounded to form a limiting slot 1121b. The reset piece 130 can be arranged in the limit groove 1121b and contacted with the two limit plates 1121a, so that the radial position of the reset piece 130 is stable, and the middle part of the reset piece 130 does not twist and deflect.

Referring to fig. 2 and 3 again, in one embodiment, a chute 1124 is formed on the bracket 1100. The shutter 1200 is in sliding engagement with the chute 1124, and the position of the shutter 1200 can be limited by the walls of the chute 1124, such that the shutter 1200 opens or closes the sump 210 along the desired path of movement.

Referring to fig. 2 in combination with fig. 4, in one embodiment, the rack 1100 includes a first rack 1110 and a second rack 1120. The wall of the oil bin 210 is provided with a matching opening 211, and the matching opening 211 can be communicated with the inside of the oil bin 210. The first bracket 1110 is used to seal the mating port 211 of the oil sump 210. In other words, in this embodiment, the first bracket 1110 may be enclosed to form a part of the oil sump 210, or the first bracket 1110 and the second bracket 1120 may be integrally enclosed to form a part of the oil sump 210, and the first bracket 1110 and the mating opening 211 are in sealing fit to make the oil sump 210 be in a closed state.

The first support 1110 is sleeved outside the second support 1120, and since the first support 1110 is used for sealing fit with the fit opening 211 and has sealing property, the first support 1110 is sleeved outside the second support 1120, so that the sealing property of the first support 1110 and the second support 1120 can be ensured, and the nebulizable medium is prevented from leaking from the position between the first support 1110 and the second support 1120.

The second bracket 1120 is provided with a second communication port 1122, and the second communication port 1122 is used for communicating with the oil bin 210. The shutter 1200 is slidably disposed on the second housing 1120 and has an open position and a closed position. The first communication port 1221 communicates with the second communication port 1122 when in the open position. When in the closed position, the first communication port 1221 is offset from the second communication port 1122, and the shutter 1200 closes the second communication port 1122.

Briefly, the first bracket 1110 is sealingly engaged with the engagement opening 211 and serves to support the second bracket 1120. A second bracket 1120 is provided within the first bracket 1110 for carrying the shield 1200. The shutter 1200 slides relative to the second bracket 1120 to a position where the first communication port 1221 communicates with the second communication port 1122, enabling the oil reservoir 210 to be opened. When the reset member 130 drives the shutter 1200 to reset, the first communication port 1221 and the second communication port 1122 are staggered, and the shutter 1200 closes the second communication port 1122, thereby closing the oil reservoir 210.

In one embodiment, the material of the first bracket 1110 may be a plastic material with sealing performance, such as silica gel. The material of the second bracket 1120 may be oil resistant plastic to meet the long-term contact with nebulizable medium. The material of the shutter 1200 and the reset element 130 may be a metal material such as stainless steel.

Referring to fig. 5, when the first communication port 1221 communicates with the second communication port 1122, the filler pipe 20 can be inserted through both the first communication port 1221 and the second communication port 1122 by selecting a filler pipe 20 of a proper size. At this time, the filler pipe 20 can abut against the inner wall of the first communication port 1221 and the inner wall of the second communication port 1122 to define the position of the shielding member 1200 relative to the second bracket 1120, so that the position of the shielding member 1200 in the process of filling oil is stable, and the nebulizable medium can be conveniently injected into the oil sump 210 through the filler pipe 20.

Referring to fig. 2, in one embodiment, the mounting slot 1121 and the sliding slot 1124 are disposed on the second bracket 1120. The first communication port 1221 may specifically be opened on the baffle 1220. The baffle 1220 extends into the chute 1124 and is in sliding engagement with the second bracket 1120. When the reset member 130 drives the shutter 1200 to reset, the baffle 1220 can close the second communication port 1122 to seal the oil sump 210.

Referring to fig. 2 to 5, in one embodiment, the first communication ports 1221 and the second communication ports 1122 are spaced along the sliding direction of the shutter 1200. In this way, the shutter 1200 can slide to a position where the first communication port 1221 and the second communication port 1122 are facing each other, and the reset member 130 can push the shutter 1200 to slide to a position where the first communication port 1221 and the second communication port 1122 are offset from each other.

With continued reference to fig. 2-5, in one embodiment, the shield 1200 is sandwiched between the first frame 1110 and the second frame 1120, with the first frame 1110 abutting the shield 1200 to maintain contact with the second frame 1120. In other words, by the first bracket 1110 cooperating with the second bracket 1120 to limit the position of the shutter 1200, leakage does not occur when the shutter 1200 closes the oil reservoir 210; when the shutter 1200 opens the oil reservoir 210, the nebulizable medium does not leak out through the area other than the first communication port 1221.

Referring to fig. 4 and 5, in one embodiment, at least one abutment 1112 protrudes from the first support 1110 toward the second support 1120, and the shielding member 1200 is kept in close contact with the second support 1120 under the abutment of the abutment 1112 to avoid leakage.

Referring again to fig. 2, in one embodiment, a seal 1123 is provided on the second bracket 1120 adjacent to the side of the shield 1200. A seal ring 1123 is provided around the second communication port 1122, and the seal ring 1123 abuts against the shutter 1200. On the other hand, when the first communication port 1221 communicates with the second communication port 1122, the sealing ring 1123 prevents the nebulizable medium from flowing into the gap between the first holder 1110 and the second holder 1120, thereby avoiding contamination of the holder 1100. On the other hand, when the shutter 1200 is reset, the nebulizable medium adhering to the inner wall of the first communication port 1221 and the vicinity thereof can be scraped off by the seal ring 1123, so as to avoid contamination of the first bracket 1110 and the second bracket 1120 by the nebulizable medium sliding to other positions of the second bracket 1120 with the shutter 1200.

Referring to fig. 2, in one embodiment, an opening 1111 is formed on the first bracket 1110, and the first communication port 1221 communicates with the opening 1111. In this manner, the filler pipe 20 is facilitated to extend between the first bracket 1110 and the second bracket 1120 through the opening 1111 to drive the sliding of the shutter 1200.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
