The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items.

In addition, the technical features mentioned in the different embodiments of the utility model described below can be combined with one another as long as they do not conflict with one another.

The liquid storage device is used for being matched with the ultrasonic atomization sheet, and provides atomized liquid for the ultrasonic atomization sheet so that the ultrasonic atomization sheet can carry out ultrasonic atomization on the atomized liquid.

Referring to fig. 1-3, a liquid reservoir 100 according to one embodiment of the present utility model includes a housing 110, a liquid guiding support 120, a liquid guiding member 140, and a liquid guiding stop member 130 nested with the liquid guiding support 120. The liquid guiding support 120, the liquid guiding stop 130 and the liquid guiding member 140 are all installed in the housing 110, and the liquid guiding member 140 is used for conducting the atomized liquid to the ultrasonic atomization sheet.

In some embodiments, the ultrasonic atomizing sheet may be an ultrasonic mesh atomizing sheet, mainly comprising a piezoelectric ceramic element and a mesh element; typically, the mesh element has thousands of precisely shaped holes around which the piezoelectric ceramic element is wrapped. Due to the rapid vibration of the piezo-ceramic element, the atomized liquid is sucked into the pores of the grid element and atomized, resulting in a very uniform droplet size. In some embodiments, the ultrasonic atomizing plate may also generate capillary waves directly at the liquid surface using only the piezoelectric ceramic element, thereby atomizing the atomized liquid. In some embodiments, the ultrasonic atomizing plate may also be disposed in the reservoir using a piezoelectric transducer, driven by a high frequency ac power source, and emits ultrasonic waves focused on the surface of the atomized liquid, thereby atomizing the atomized liquid.

Specifically, the housing 110 is provided with a first housing chamber 111 and a first opening 112 communicating with the first housing chamber 111, the first housing chamber 111 being for loading an atomized liquid. The liquid guiding support 120 is mounted in the first accommodating cavity 111, and the liquid guiding support 120 is provided with a second accommodating cavity 121 and a first communication structure 122, and the second accommodating cavity 121 accommodates the liquid guiding member 140. The liquid guiding and stopping member 130 is provided with a third accommodating cavity 131 and a second communicating structure 132.

When the first communication structure 122 and the second communication structure 132 are in the conducting state, the first receiving cavity 111 and the second receiving cavity 121 are conducted, and under the action of the channel formed by the first communication structure 122 and the second communication structure 132, the atomized liquid enters the second receiving cavity 121 from the first receiving cavity 111 and gradually infiltrates the liquid guide member 140, and by utilizing the capillary phenomenon, the atomized liquid gradually moves to one end of the liquid guide member 140 for abutting against the ultrasonic atomization sheet, thereby realizing the conduction of the atomized liquid. When the first communication structure 122 and the second communication structure 132 are in the same state. When the first communication structure 122 and the second communication structure 132 are in the off state, the first accommodating cavity 111 and the second accommodating cavity 121 are substantially isolated. Through such design, can set up liquid guide 140 in reservoir 100, be favorable to the liquid guide stable, moreover through the regulation of the different states of first communication structure 122 and second communication structure 132, can reduce liquid guide 140 and deposit in a long-term to atomizing liquid safety or pleasing to the eye influence. Meanwhile, the liquid storage device 100 has the independent first accommodating cavity 111 for loading liquid for atomization by the ultrasonic atomization sheet, so that the pollution of the liquid is avoided, the liquid storage device has certain portability, and the risk that the liquid guide piece 140 is soaked in atomized liquid for a long time is reduced under the action of the liquid guide through-stop piece 130, and the service life of the liquid guide piece 140 is prolonged.

It is noted herein that the substantial isolation includes both the first communication structure 122 not communicating or not communicating approximately with the second communication structure 132. By the treatment such as the seal design, in an ideal state, the atomized liquid cannot enter the second accommodating chamber 121 from the first accommodating chamber 111, and at this time, it can be understood that the first communicating structure 122 is not communicated with the second communicating structure 132; however, in some situations, the accuracy of the assembly process is limited, or in the case that no sealing design is performed, there is a mounting gap or other small gap between the liquid guiding support member 120 and the liquid guiding stop member 130, so that the atomized liquid can still enter the second accommodating cavity 121 at a relatively slow speed and adhere to the surface of the liquid guiding member 140, and at this time, it can be understood that the first communicating structure 122 is approximately not communicated with the second communicating structure 132.

In some embodiments, the housing 110 is at least partially made of a transparent material, such as transparent plastic, and the transparent housing 110 can timely reflect the height of the atomized liquid in the liquid reservoir 100, so that a user can timely learn about the remaining condition of the atomized liquid in the liquid reservoir 100, which is helpful for improving the user experience.

The liquid guiding support piece 120 and the liquid guiding through stop piece 130 are nested with each other, namely, the liquid guiding support piece 120 is sleeved on the periphery of the liquid guiding through stop piece 130, and the liquid guiding piece 140 is arranged in the third accommodating cavity 131; the liquid guiding and stopping member 130 may wrap the outer periphery of the liquid guiding and supporting member 120, and the liquid guiding member 140 may be disposed in the second accommodating cavity 121 at this time, specifically, may be disposed according to actual needs.

For convenience of explanation, the following description will be given by taking the case where the liquid guiding support member 120 is sleeved on the outer periphery of the liquid guiding stop member 130 as an example, but the scheme of the present application is not limited to the following description, and the structure described below is equally applicable to the case where the liquid guiding stop member 130 wraps the outer periphery of the liquid guiding support member 120.

In some embodiments, the liquid reservoir 100 further includes an elastic member 150, where the elastic member 150 is disposed between the liquid guiding support 120 and the liquid guiding stop member 130, and two ends of the elastic member 150 respectively abut against the bottom wall of the liquid guiding support 120 and the bottom wall of the liquid guiding stop member 130. The elastic member 150 may be a spring or an elastic silica gel block, or may be other structures with elastic properties, and the specific form thereof is not limited, and in this embodiment, the elastic member 150 is a spring.

When an external force acts on the liquid guide member 140 or the liquid guide through-stop member 130, and pushes the liquid guide through-stop member 130 to move towards the bottom wall of the liquid guide support member 120, the elastic member 150 is gradually squeezed, and after a certain distance of movement, the first communication structure 122 and the second communication structure 132 are in a conductive state, as shown in fig. 4, the atomized liquid enters the second receiving cavity 121 from the first receiving cavity 111 and infiltrates the liquid guide member 140, and at this time, the elastic member is in a compressed state. When the external force is removed, the elastic member 150 returns to deform, and the liquid guiding member 130 and the liquid guiding member 140 move away from the bottom wall of the liquid guiding support member 120 under the action of the elastic member 150, so that the first communication structure 122 and the second communication structure 132 are in a closed state, and the first receiving cavity 111 and the second receiving cavity 121 are substantially isolated.

By providing the elastic member 150, the liquid guide and stop member 130 can be reset in time when the liquid reservoir 100 is idle, and the first communication structure 122 and the second communication structure 132 are in a cut-off state, so that the influence on the atomized liquid caused by long-time soaking of the liquid guide member 140 in the atomized liquid is reduced.

In some embodiments, as shown in fig. 1 or 3, the reservoir 100 further includes a housing cover 160, where the housing cover 160 covers the housing 110, which helps to reduce the risk of external forces acting directly on the liquid guide 140. It can be appreciated that when the liquid reservoir 100 is idle, the liquid reservoir 100 can be provided with the cover 160, so as to prevent the liquid guide 140 from being directly exposed to the outside, which is helpful for prolonging the service life of the liquid guide 140. When the liquid reservoir 100 is in use, the cover 160 needs to be separated from the housing 110, so that the liquid guide 140 can be in direct contact with the atomizer to realize atomization.

In some embodiments, referring to fig. 5 and fig. 6, the liquid guiding support 120 includes a main body 123 and a plug portion 124 connected to the main body 123, the main body 123 is provided with a first communication structure 122 and a second receiving cavity 121, the plug portion 124 is located at one end of the main body 123, and the plug portion 124 is used for sealing the first opening 112. It should be appreciated that the peripheral dimension of the body portion 123 should be smaller than the peripheral dimension of the plug portion 124 so that the body portion 123 may enter the first receiving cavity 111. In this embodiment, the main body 123 is hollow and square, the main body 123 includes a cylinder 1231 and a bottom cover 1232 detachably mounted to the cylinder 1231, the cylinder 1231 is provided with a second accommodating cavity 121, and the bottom cover 1232 is located at one end of the cylinder 1231 away from the first opening 112.

It should be appreciated that the bottom cover 1232 and the barrel 1231 may be detachably connected by a threaded connection or a clamping connection; or one side end of the bottom cover 1232 is hinged with the cylinder 1231, and the other side end of the bottom cover 1232 is clamped with the cylinder 1231 through a clamping structure, and at this time, the bottom cover 1232 can rotate relative to the cylinder 1231 to open or close the cylinder 1231. The specific connection manner is not limited as long as the detachable installation between the bottom cover 1232 and the cylinder 1231 can be realized. In this embodiment, a scheme of realizing connection between the bottom cover 1232 and the cylinder 1231 by means of clamping is described, specifically, a through clamping interface 12311 is provided on a side wall of one end of the cylinder 1231 far away from the first opening 112, a protruding clamping block 12321 is provided on an outer periphery of the bottom cover 1232, and the bottom cover 1232 is pushed in a direction of the cylinder 1231 during installation, and the clamping block 12321 is clamped to the clamping interface 12311, thereby completing installation between the bottom cover 1232 and the cylinder 1231. It will be appreciated that, for ease of installation, the peripheral edge of the bottom cover 1232 may be provided with an outer chamfer and the end edge of the barrel 1231 provided with an inner chamfer, which is beneficial to reducing the resistance experienced by the bottom cover 1232 as it is pushed toward the barrel 1231.

Further, the plug portion 124 is detachably mounted to the housing 110, such as by a threaded connection or a snap fit. As shown in fig. 3, the housing 110 is provided with a bayonet 113 in communication with the first accommodating cavity 111, the plug portion 124 is provided with a clamping block 1241, and the clamping block 1241 is clamped to the bayonet 113, so that the liquid guiding support 120 is detachably connected to the housing 110. It is understood that the latch 1241 is provided with an inclined surface toward the first receiving chamber 111 so that resistance can be reduced when the liquid guide support 120 is mounted to the housing 110. In the present embodiment, four clamping blocks 1241 are disposed on the side wall of the plugging portion 124, four bayonets 113 are disposed on the housing 110, and one clamping block 1241 is correspondingly clamped to one bayonet 113, so as to improve the connection stability between the plugging portion 124 and the housing 110. It can be appreciated that the opening size of the bayonet 113 is only slightly larger than the size of the latch 1241, i.e. the latch 1241 can be engaged with the bayonet 113, so as to reduce the rotation of the plug 124 relative to the housing 110.

In some embodiments, the inner wall surface of the housing 110 at the first opening 112 is partially recessed to form the limiting step 114, the plug portion 124 is provided with a positioning protruding edge 1242, and the positioning protruding edge 1242 abuts against the limiting step 114, so as to reduce the risk that the plug portion 124 is totally trapped in the first receiving cavity 111 under the action of external force, which is beneficial to improving the stability of the liquid reservoir 100. It can be appreciated that when the plug portion 124 pushes a certain distance into the housing 110, the positioning protruding edge 1242 abuts against the limiting step 114, and the clamping block 1241 is just clamped in the bayonet 113, which is beneficial to improving the installation efficiency.

Further, the housing 110 is provided with a through rotation stopping notch 115 at the first opening 112, the plug portion 124 is provided with a rotation stopping protrusion 1243, and the rotation stopping protrusion 1243 is embedded in the rotation stopping notch 115. In this manner, rotation of the stopper 124 relative to the housing 110 may be reduced, which may be beneficial to improving the stability of the reservoir 100.

The direction of the central axis of the liquid guiding stopper 130 is defined as a first direction X, and the direction perpendicular to the first direction X is defined as a second direction Y.

As shown in fig. 5-7, in some embodiments, the liquid guiding and stopping member 130 includes a stopping housing 133 and a stopper 134 extending from an outer side wall of the stopping housing 133, where the stopping housing 133 is shaped as a cylinder, and the stopping housing 133 is provided with a second communication structure 132 capable of communicating with the second accommodating cavity 121. The end of the main body 123 away from the plugging head 124 is provided with a limiting groove 1233, a limiting block 134 is disposed in the limiting groove 1233, and the limiting block 134 is used for limiting the moving distance of the through-stop housing 133 relative to the main body 123, so as to enable the liquid guiding through-stop member 130 to move to a proper position relative to the liquid guiding support member 120 under the abutting of the elastic member 150. That is, when the limiting block 134 abuts against the side wall of the limiting groove 1233 in the first direction X, the first communicating structure 122 and the second communicating structure 132 are in the cut-off state, so that the liquid in the first accommodating cavity 111 is reduced to penetrate into the second accommodating cavity 121 without obstruction, and the liquid guiding member 140 is soaked. It can be appreciated that in other embodiments, the side wall of the liquid guiding and stopping member 130 may be provided with a limiting groove 1233, the side wall of the liquid guiding and supporting member 120 is provided with a limiting block 134, and the limiting block 134 is clamped in the limiting groove 1233, so that the distance that the liquid guiding and stopping member 130 moves relative to the liquid guiding and supporting member 120 can be limited, which is not described herein.

The liquid guide 140 may be made by pressing fibers into a column to facilitate the capillary phenomenon to guide the liquid to the atomizing assembly of the atomizer for atomization. Of course, the liquid guide 140 may be made of other materials, such as cotton, etc., so long as the liquid guide is realized. In this embodiment, the liquid guiding member 140 is made by pressing fibers into a columnar body. The liquid guide through-stop member 130 can avoid the long-time soaking of the liquid guide member 140 in the atomized liquid, so that the risk that the fibers of the liquid guide member 140 are soaked and dispersed by the liquid for a long time and dispersed along with the liquid is reduced, the risk that the dispersed fibers influence the beauty and safety of the atomized liquid is reduced, and the user experience is improved.

In some embodiments, please refer to fig. 2 and fig. 7, the liquid guiding and stopping member 130 further includes a limiting protrusion 135 protruding from the stopping housing 133, the limiting protrusion 135 is located at an end of the stopping housing 133 away from the plugging head 124, and the elastic member 150 is sleeved on the limiting protrusion 135, so as to avoid the elastic member 150 from deviating from the installation position in the process of being extruded. It can be appreciated that the bottom cover 1232 is provided with a through hole 12322, and the caliber of the through hole 12322 is larger than the size of the limiting protrusion 135 in the second direction Y, so that when the liquid guiding and stopping member 130 presses the elastic member 150, the limiting protrusion 135 can move towards the inside of the through hole 12322, thereby reducing the risk of interference caused by the bottom cover 1232 to the movement of the liquid guiding and stopping member 130.

Further, as shown in fig. 2, the limiting protrusion 135 is provided with a through hole 136, and the through hole 136 is communicated with the first accommodating cavity 111 and the third accommodating cavity 131, so that atomized liquid can enter the third accommodating cavity 131 through the through hole 136, which is beneficial to fully utilizing the atomized liquid, and meanwhile, is beneficial to pre-wetting the liquid guide member 140, when a user installs the liquid reservoir 100 to the ultrasonic atomizer, the liquid guide member 140 can directly conduct the atomized liquid, so that the liquid guide member 140 is prevented from being soaked by the atomized liquid after waiting a period of time when the first communicating structure 122 and the second communicating structure 132 are switched from the cut-off state to the conducting state, the atomization effect of the ultrasonic atomization sheet is ensured, and the user experience is improved.

In some embodiments, one of the side walls of the liquid guide support 120 and the side walls of the liquid guide stopper 130 is provided with a sealing structure. The number of the sealing structures is set according to the requirement, namely, one or more sealing structures can be used for preventing the atomized liquid from passing through the second communication structure 132, so that the risk that the liquid guide 140 is directly soaked in the atomized liquid is reduced. In this way, when the first communication structure 122 and the second communication structure 132 are in the off state, the first communication structure 122 and the second communication structure 132 are staggered, and the sealing structure substantially blocks the conduction path between the first communication structure 122 and the second communication structure 132, and the first accommodating cavity 111 is substantially isolated from the second accommodating cavity 121.

Substantially blocking includes providing a thorough barrier or isolation of the aerosolized liquid entering the second receiving chamber 121, as well as providing some barrier or isolation. For example, an installation gap or other micro gap may exist between the side wall of the liquid guiding support member 120 and the liquid guiding stop member 130 due to an assembly process or other factors, so that the atomized liquid can still slowly enter the second accommodating cavity 121, and at this time, it may be understood that the sealing structure substantially blocks the conducting path between the first communicating structure 122 and the second communicating structure 132; for example, the atomized liquid can not enter the second receiving chamber 121 completely by a tighter seal design.

The sealing structure can be a sealing convex edge formed by protruding from the inner wall surface of the object, and can also be a sealing ring for assisting sealing. Soaking means that the atomized liquid directly contacts the liquid guide 140 in a large area, and soaking means that the atomized liquid contacts the liquid guide 140 in a small area through the installation gap and wets the surface of the liquid guide 140 by diffusion.

Further, when the sealing structures are disposed on the outer wall surface of the liquid guiding and stopping member 130, there are a plurality of second communication structures 132, and two sealing structures are disposed on two sides of each second communication structure 132 along the first direction X. Alternatively, when the sealing structures are disposed on the inner wall surface of the liquid guiding support 120, the number of the first communicating structures 122 is plural, and two sealing structures are disposed on two sides of each first communicating structure 122 along the first direction X.

In some embodiments, as shown in fig. 7, the outer wall surface of the through housing 133 of the liquid guiding and stopping member 130 is partially protruded and formed with a plurality of sealing flanges 137, the plurality of sealing flanges 137 are spaced apart along the first direction X, and the plurality of sealing flanges 137 are abutted against the inner wall surface of the main body 123. In other embodiments, as shown in fig. 8, the outer wall surface of the liquid guiding and stopping member 130 is partially recessed to form a plurality of annular grooves 1301 arranged at intervals, the liquid guiding and stopping member 130 further includes a plurality of sealing rings 138, and a sealing ring 138 is sleeved on one annular groove 1301; alternatively, the outer wall surface of the liquid guiding stopper 130 is protruded to form a sealing flange. In this way, when the liquid guiding and stopping member 130 is mounted to the liquid guiding and supporting member 120, the plurality of sealing rings 138 abut against the inner wall surface of the liquid guiding and supporting member 120, so as to substantially block the conducting path between the first communicating structure 122 and the second communicating structure 132.

In other embodiments, when the liquid guiding and stopping member 130 is sleeved on the liquid guiding support member 120, the sealing structure may have two arrangement modes, specifically, the inner wall surface of the liquid guiding and stopping member 130 is provided with a plurality of sealing flanges 137, or the outer wall surface of the liquid guiding support member 120 is provided with a plurality of sealing rings 138 or a plurality of sealing flanges 137, which also can substantially block the conducting path between the first communication structure 122 and the second communication structure 132, which is not described herein again.

In some embodiments, referring to fig. 3, 6 and 7, the first communication structure 122 includes a plurality of first communication holes 1221, the plurality of first communication holes 1221 are distributed on the outer wall of the liquid guiding support 120 at intervals along the first direction X, and the first communication holes 1221 penetrate through the wall surface of the liquid guiding support 120, so that the atomized liquid can enter the second receiving cavity 121 through the plurality of first communication holes 1221. The second communication structure 132 includes a plurality of second communication holes 1321, the plurality of second communication holes 1321 are distributed on the outer wall of the liquid guiding and stopping member 130 along the first direction X, and the plurality of second communication holes 1321 communicate the second accommodating cavity 121 with the third accommodating cavity 131.

It can be understood that when the liquid guiding and stopping member 130 is not acted by an external force, under the abutment of the elastic member 150, the limiting block 134 abuts against the inner sidewall of the limiting groove 1233, and is blocked by the outer wall of the liquid guiding and stopping member 130, the first communicating holes 1221 and the second communicating holes 1321 are in a blocking state, and at this time, the first communicating holes 1221 and the second communicating holes 1321 are staggered, so that the first accommodating cavity 111 and the second accommodating cavity 121 are substantially isolated, and meanwhile, under the blocking of the sealing structure, the liquid guiding member 140 is prevented from being soaked in the atomized liquid. When the liquid guide stopper 130 is pushed against the elastic member 150 and the first communication hole 1221 is made to communicate with the second communication hole 1321, the atomized liquid passes through the first communication hole 1221 and the second communication hole 1321, so that the liquid guide member 140 is immersed in the atomized liquid.

The staggered arrangement means that the plurality of first communication holes 1221 and the plurality of second communication holes 1321 do not overlap in the second direction Y, the plurality of first communication holes 1221 are covered by the wall surface of the liquid guiding stopper 130, and the plurality of second communication holes 1321 are covered by the wall surface of the liquid guiding supporter 120.

In some embodiments, the first communication holes 1221 may be disposed on a plurality of sides of the liquid guiding support 120, as shown in fig. 8, and the second communication holes 1321 may be disposed on a plurality of sides of the liquid guiding stop 130, so that the liquid container 100 can quickly infiltrate the liquid guiding member 140 during use.

The first communication structure 122 and the second communication structure 132 may include other structures besides the above-described structure, and the first communication structure 122 and the second communication structure 132 may be other structures. For example, as shown in fig. 6-7, the first communication structure 122 includes a plurality of first communication ports 1222, the plurality of first communication ports 1222 are distributed on the outer wall of the liquid guiding support 120 at intervals along the first direction X, the first communication ports 1222 penetrate the wall surface of the liquid guiding support 120, the second communication structure 132 includes a plurality of second communication ports 1322, and the plurality of second communication ports 1322 are distributed on the outer wall of the liquid guiding stop 130 along the first direction X. Wherein, the opening sizes of the first communication port 1222 and the second communication port 1322 are both larger than the apertures of the first communication hole 1221 and the second communication hole 1321, which is helpful for the atomized liquid to infiltrate the liquid guide 140 more quickly through the channel formed by the first communication port 1222 and the second communication port 1322, so as to ensure that the liquid reservoir 100 can stably supply liquid to the ultrasonic atomized sheet when in use. Similarly, when the first communication port 1222 and the second communication port 1322 are in the closed state, the first communication port 1222 and the second communication port 1322 are staggered.

The liquid storage device 100 provided by the embodiment of the application comprises a shell 110, a liquid guide support piece 120, a liquid guide through-stop piece 130, a liquid guide piece 140, wherein a first communication structure 122 is arranged on the liquid guide support piece 120, a second communication structure 132 is arranged on the liquid guide through-stop piece 130, and when the first communication structure 122 and the second communication structure 132 are in a conducting state, atomized liquid enters a second containing cavity 121 from a first containing cavity 111 and is attached to the liquid guide piece 140; when the first communication structure 122 and the second communication structure 132 are in the off state, the first accommodating cavity 111 and the second accommodating cavity 121 are substantially isolated; by arranging the liquid guide part in the liquid reservoir 100, the liquid guide is stable; and through the adjustment of the different states of the first communication structure 122 and the second communication structure 132, the influence on the safety or the appearance of the atomized liquid when the liquid guide 140 is stored for a long time can be reduced.
