Abstract
Description
Technical Field
[0001] This application belongs to the field of beauty product and equipment technology, and in particular relates to a liquid storage device and beauty container for storing liquid beauty products. Background Technology
[0002] Currently, most beauty devices on the market require a removable liquid reservoir to hold liquid beauty products such as serums or nutrient solutions. Since the reservoir needs to be disassembled for filling / cleaning and then reassembled into the device, and it must be waterproof and leak-proof, existing technologies generally use a threaded structure for sealing. However, this method is slow and inefficient due to the need for frequent rotation during installation, and leaks can occur if the reservoir is not properly tightened. Utility Model Content
[0003] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide a liquid storage device that is loaded and unloaded by pressing.
[0004] The technical solution adopted in this application embodiment is a liquid storage device, comprising:
[0005] The base has a seat cavity inside;
[0006] A liquid storage tank has a liquid outlet at its bottom, and the liquid outlet is equipped with a resilient cut valve that remains closed when no external force is applied. The liquid storage tank can be installed into the seat cavity of the base with the liquid outlet facing downwards.
[0007] A locking mechanism is provided on the base and can extend into the seat cavity. The locking mechanism is used to lock the liquid storage tank when the liquid storage tank is installed in the seat cavity, and to release the liquid storage tank when the liquid storage tank is pressed down.
[0008] A pushing mechanism is located at the bottom of the base and can move along the loading and unloading direction of the liquid storage tank to push the elastic cut valve open when the liquid storage tank is installed in the seat cavity, and push the liquid storage tank upward when the liquid storage tank is pressed down and released by the locking mechanism.
[0009] In an optional embodiment, the pushing mechanism includes a push rod with through holes extending to its opposite ends. The upper end of the push rod has a pushing portion and a sealing ring. The sealing ring surrounds the outside of the pushing portion. The pushing portion has an annular cross-section and a flow notch. When the liquid storage tank is inserted into the seat cavity, the sealing ring presses against the periphery of the elastic cut valve, and the pushing portion opens the valve port of the elastic cut valve. Liquid in the liquid storage tank flows into the through hole of the push rod through the flow notch. The pushing mechanism has a simple and reasonable structure, effectively opening the valve port of the elastic cut valve and sealing its edge.
[0010] In an optional embodiment, the resilient cut valve includes a hollow cylindrical valve body and an annular flange extending outward from the outer periphery of the first end of the valve body. The first end of the valve body is open, and the second end of the valve body is closed and has a cut. The cut forms the valve port. The open first end of the valve body is opposite to the liquid outlet, and the annular flange is tightly connected to the outer periphery of the liquid outlet.
[0011] The pushing part sinks into the sealing ring and, when the liquid storage tank is installed into the seat cavity, pushes against the end face of the second end of the valve body to open the valve port. The sealing ring pushes against the annular flange, pressing it tightly against the outer periphery of the outlet. The flexible cut-out valve can seal the outlet and can be opened under the pushing action of the pushing part, with a simple and reasonable structural design.
[0012] In an optional embodiment, the pushing mechanism further includes an elastic component disposed on the push rod. This elastic component applies an upward force to the push rod, so that when the liquid storage tank, already inserted into the seat cavity, is pressed downwards again and released by the locking mechanism, the elastic component drives the push rod upwards and pushes the liquid storage tank, causing it to pop out of the seat cavity. The elastic component allows the liquid storage tank to automatically spring upwards, facilitating its removal from the base.
[0013] In an optional embodiment, the base has a mounting cavity at its bottom that communicates with the seat cavity. A bottom cover is fixed to the bottom of the mounting cavity. The top rod is disposed in the mounting cavity, and the bottom end of the top rod passes through the bottom cover and extends out of the mounting cavity. An annular protrusion is provided on the upper circumference of the top rod. The elastic component is a spring and is sleeved on the top rod. The two ends of the elastic component abut against the bottom cover and the annular protrusion, respectively.
[0014] In an optional embodiment, the locking mechanism includes a press-fit latch, which includes a body and a latch movably disposed on the body;
[0015] The bottom of the liquid storage tank has a protrusion. When the liquid storage tank is inserted into the seat cavity, the protrusion engages with the latch, locking the liquid storage tank onto the base. When the liquid storage tank is pressed down, the protrusion presses down against the latch, causing the latch to spring upward and open outward, releasing the lock on the protrusion. The liquid storage tank then moves upward under the action of the elastic component and the push rod. This locking mechanism has a simple and reasonable structure, enabling locking and unlocking of the liquid storage tank through pressing. It is simple and convenient to operate, and has a good locking effect.
[0016] In an optional embodiment, the base has a groove communicating with the seat cavity on its periphery; the body of the press buckle is fixed in the groove, and the press buckle has a buckle groove, the opening of the buckle groove facing the center of the seat cavity, and the lower groove wall protruding from the upper groove wall in the direction toward the center of the seat cavity, so that when the liquid storage tank is inserted into the seat cavity, the boss of the liquid storage tank can act on the lower groove wall and press down against the lower groove wall, so that the buckle moves down and closes, locking the boss in the buckle groove.
[0017] In an optional embodiment, the bottom outer peripheral wall of the liquid storage tank tapers inward and extends downward to form a neck, and the outer peripheral edge of the neck extends outward to form the boss; and / or
[0018] The resilient cut valve is located inside the neck, and the outer periphery of the resilient cut valve is pressed against the outer periphery of the liquid outlet by a fixed cover.
[0019] In an optional embodiment, the top of the liquid storage tank is open and has a lid, the lid having at least one slit for allowing air to enter.
[0020] This application also provides a beauty device, including a handle and an operating head disposed at one end of the handle. The beauty device also includes a liquid storage device as described in any of the above embodiments. The liquid storage device is disposed in the cavity of the handle. When the liquid storage tank of the liquid storage device is pressed down, the locking mechanism releases the liquid storage tank. Under the action of the pushing mechanism, the liquid storage tank moves upward and is exposed outside the other end of the handle, making it convenient for the user to remove the liquid storage tank from the base and the handle.
[0021] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: The liquid storage device of the embodiments of this application adopts a press-type structure, which can be assembled by pressing directly and removed by pressing again, thus achieving rapid installation and removal. During installation, it is sealed simultaneously, which can shorten the assembly time and improve the user experience.

[0042] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.
[0043] This application provides a liquid storage device for containing beauty or skincare serums or nutrient solutions. The liquid storage device is mounted on a beauty device to provide the device with the desired beauty liquid.
[0044] like Figures 1 to 5As shown, the liquid storage device includes a base 1, a liquid storage tank 2, a locking mechanism 4, and a pushing mechanism 5. The base 1 has a cavity 11 extending to its top, meaning the top of the base 1 has an opening that connects the cavity 11 to the outside. The bottom of the liquid storage tank 2 has a liquid outlet 21, which is equipped with a resilient cut-off valve 3 that remains closed when not subjected to external force. The resilient cut-off valve 3 can open under external force, controlling the opening and closing of the liquid outlet 21, thereby controlling whether the liquid in the liquid storage tank 2 flows out. The liquid storage tank 2 can be inserted into the cavity 11 of the base 1 with the liquid outlet 21 facing downwards. A locking mechanism 4 is mounted on the base 1 and extends into the seat cavity 11. The locking mechanism 4 locks the liquid storage tank 2 when it is inserted into the seat cavity 11, and releases it when the liquid storage tank 2 is pressed down within the base 1, allowing it to be removed from the base 1. A pushing mechanism 5 is located at the bottom of the base 1, with its upper part extending into the seat cavity 11. The pushing mechanism 5 can move along the loading and unloading direction of the liquid storage tank 2. When the liquid storage tank 2 is inserted into the seat cavity 11, the pushing mechanism 5 pushes the elastic cut valve 3 to open and allow liquid to flow out. When the liquid storage tank 2 is pressed down and released by the locking mechanism 4, the pushing mechanism 5 pushes the liquid storage tank 2 upwards.
[0045] The liquid storage tank 2 of the liquid storage device in this embodiment is assembled into the base 1 by pressing and removed from the base 1 by pressing again, which can shorten the assembly time and improve the assembly efficiency. Moreover, the opening and closing of the liquid outlet 21 is controlled by the elastic cut valve 3, which can close the liquid outlet 21 when the liquid storage tank 2 is installed into or removed from the base 1 to avoid leakage and improve the user experience.
[0046] It should be noted that the orientations of "up," "down," "top," and "bottom" in this application are defined based on the posture of the liquid storage tank 2 when it is installed in the seat cavity 11 and the outlet 21 of the liquid storage tank 2 is facing downwards. The resilient slit valve 3 refers to a valve that is elastic and has a slit 311, which serves as the valve port. Under non-stressed conditions, i.e., in its natural state, the resilient slit valve 3 remains closed due to the elasticity of the valve itself and the narrowness of the slit 311, preventing liquid in the liquid storage tank 2 from flowing out through the slit. When the resilient slit valve 3 is pushed by the pusher mechanism 5, the slit 311 opens, and liquid in the liquid storage tank 2 flows out through the slit 311.
[0047] In some embodiments, such as Figure 2As shown, the push mechanism 5 includes a push rod 51, which has through holes 511 extending to its opposite ends. The upper end of the push rod 51 has a push part 52 and a sealing ring 53. The sealing ring 53 surrounds the outside of the push part 52. The cross-section of the push part 52 is annular and has a flow notch 521. When the liquid storage tank 2 is installed into the seat cavity 11, the sealing ring 53 presses against the periphery of the elastic cut valve 3, pushing the periphery of the elastic cut valve 3 towards the outer periphery of the outlet 21 to prevent liquid from flowing to the periphery. The push part 52 opens the valve port (cut 311) of the elastic cut valve 3, and the liquid in the liquid storage tank 2 flows into the through hole 511 of the push rod 51 through the flow notch 521, and then flows into the spray port or atomizing port of the beauty device.
[0048] The number of flow notches 521 on the pusher section 52 is unlimited, but there must be at least one. For example... Figure 7 As shown in the figure, this embodiment illustrates four flow notches 521, which are evenly distributed on the pusher portion 52 to allow the liquid in the storage tank 2 to flow quickly, smoothly, and evenly into the push rod 51. The flow notches 521 extend from the top of the pusher portion 52 downwards, that is, the flow notches 521 extend to the top of the pusher portion 52, so that the liquid in the storage tank 2 and the liquid entering the elastic cut valve 3 can all flow out completely, avoiding waste.
[0049] In addition, to maintain smooth liquid flow, the cross-section of the pusher 52 is annular and concentric with the through hole 511 inside the pusher 51. The cross-section of the sealing ring 53 is also annular and is fitted over the pusher 52, with the sealing ring 53 concentric with the pusher 52.
[0050] In some embodiments, such as Figure 3 and Figure 6 As shown, the resilient cut-out valve 3 includes a hollow cylindrical valve body 31 and an annular flange 32 extending outward from the outer periphery of the first end of the valve body 31. The first end of the valve body 31 is open, and the second end of the valve body 31 is closed and has a cut-out 311, which forms a valve port. The open first end of the valve body 31 is opposite to the liquid outlet 21, and the annular flange 32 surrounds the outer periphery of the liquid outlet 21 and is tightly engaged with the outer periphery of the liquid outlet 21 (see [reference]). Figure 3 This is to prevent liquid flowing out of the outlet 21 from leaking between the annular flange 32 and the outer periphery of the outlet 21.
[0051] like Figure 2 and Figure 7As shown, the pusher 52 is recessed into the sealing ring 53, that is, the top of the pusher 52 protrudes upward from the top of the sealing ring, so that when the storage tank 2 is installed into the seat cavity 11, the top of the sealing ring 53 pushes against the annular flange 32, causing the annular flange 32 to press tightly against the outer periphery of the outlet 21. The second end of the valve body 31 extends into the sealing ring 53, and under the pushing action of the pusher 52, the valve port (cutout 311) opens, and the liquid in the storage tank 2 flows into the through hole 511 of the pusher 51 through the flow notch 521 on the pusher 52. See Figure 4 , Figure 4 The direction of the middle arrow indicates the direction of liquid flow.
[0052] The resilient cut valve 3 can be made of materials that can undergo elastic deformation, such as rubber, silicone, PVC, etc. This type of resilient valve is generally defined as a silicone valve.
[0053] The form of the notch 311 on the flexible notch valve 3 is not limited; for example, it can be a straight line, a cross, a star shape, etc. Figure 6 The cut 311 on the resilient cut valve 3 shown in the figure is cross-shaped.
[0054] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the pushing mechanism 5 also includes an elastic component 55, which is mounted on the push rod 51 and applies an upward force to the push rod 51. When the liquid storage tank 2 is inserted into the seat cavity 11, the elastic component 55 is compressed and accumulates elastic potential energy. After the liquid storage tank 2, already inserted into the seat cavity 11, is pressed down again and released by the locking mechanism 4, the elastic component 55 releases its elastic potential energy and drives the push rod 51 to push the liquid storage tank 2 upward, causing the liquid storage tank 2 to be pushed upward out of the seat cavity 11 and removed from the base 1. By providing the elastic component 55, the liquid storage tank 2 can automatically spring upward when pressed down again, facilitating its removal from the base 1.
[0055] When the liquid storage tank 2 of this application is installed into the seat cavity 11, the push part 52 at the upper end of the push rod 51 opens the cut 311 of the elastic cut valve 3, and the outer sealing ring 53, under the action of the elastic component 55, presses the outer periphery of the elastic cut valve 3 to achieve a sealing effect, preventing liquid from leaking to the edge. The liquid only flows through the flow notch 521 into the through hole 511 inside the push rod 51. By adopting the sealing structure of this embodiment, the liquid storage tank 2 is installed and disassembled in a sealed state, and no liquid will leak when moved during use.
[0056] In some embodiments, such as Figure 2As shown, the base 1 has a mounting cavity 13 at its bottom that communicates with the seat cavity 11. The mounting cavity 13 extends to the bottom end of the base 1 and is fixed with a bottom cover 14. A push rod 51 is located inside the mounting cavity 13, and the bottom end of the push rod 51 extends out of the mounting cavity 13 through the bottom cover 14. An annular protrusion 54 is provided on the upper circumference of the push rod 51. An elastic member 55 is a spring and is sleeved on the push rod 51. The two ends of the elastic member 55 abut against the bottom cover 14 and the annular protrusion 54, respectively. In this way, the push rod 51 is stably assembled at the bottom of the base 1 and can move smoothly vertically under the downward pressure of the liquid storage tank 2 and the upward spring action of the elastic member 55.
[0057] like Figure 1 As shown, the bottom cover 14 is provided with a downwardly protruding guide sleeve 15. The push rod 51 passes through the guide sleeve 15. The guide sleeve 15 is used to guide the vertical movement of the push rod 51 to prevent deviation. See [reference needed]. Figure 2 .
[0058] In some embodiments, such as Figure 1 and Figure 2 As shown, the locking mechanism 4 includes a pressing latch 41, which comprises a body 411 and a latch 412 movably disposed on the body 411. The bottom of the liquid storage tank 2 has a boss 22. When the liquid storage tank 2 is inserted into the seat cavity 11, the boss 22 engages with the latch 412, and pressing the latch 41 locks the liquid storage tank 2 onto the base 1. (See Figure 1) Figure 4 When the reservoir 2, already inserted into the seat cavity 11, is pressed down again, the boss 22 presses down against the latch 412, causing the latch 412 to spring upward and open outward, releasing the lock on the boss 22. (See below) Figure 5 The liquid storage tank 2 moves upward under the action of the elastic member 55 and can be removed from the seat cavity 11. The locking mechanism 4 has a simple and reasonable structure. It can lock and unlock the liquid storage tank 2 by pressing. It is simple and convenient to operate and has a good locking effect.
[0059] In some embodiments, continue to combine Figure 1 and Figure 2 The base 1 has a slot 12 on its periphery that communicates with the seat cavity 11; the body 411 of the pressing buckle 41 is fixed in the slot 12, and the buckle 412 of the pressing buckle 41 has a buckle groove 4121, the opening of the buckle groove 4121 facing the center of the seat cavity 11, and the lower groove wall 4122 of the buckle groove 4121 protruding from the upper groove wall 4123 in the direction towards the center of the seat cavity 11. When not under force, the buckle 412 is in an open position, opening outwards. (See [reference]) Figure 2 When the liquid storage tank 2 is inserted into the seat cavity 11, the boss 22 of the liquid storage tank 2 acts on the lower tank wall 4122 and presses downward against the lower tank wall 4122. Figure 2The direction of the middle arrow indicates the direction of force, causing the lower groove wall 4122 to move the latch 412 downwards and retract inwards to close. See [link / reference]. Figure 4 As shown, Figure 4 The middle latch 412 is in the closed state, thereby locking the boss 22 in the latch groove 4121, so that the liquid storage tank 2 is locked in the base 1 and cannot be removed. Figure 4 With the latch 412 locking the liquid tank 2 within the base 1, to remove the liquid tank 2, press the liquid tank 2 downwards again. The protrusion 22 of the liquid tank 2 presses downwards against the lower groove wall 4122, causing the entire latch 412 to spring upwards and open outwards. Figure 5 In the open state shown, the latch 412 releases the lock on the boss 22, and the push rod 51 moves upward under the action of the elastic component 55 and pushes the liquid storage tank 2 upward, so that the liquid storage tank 2 automatically pops upward and is easy for the user to take out; when the liquid storage tank 2 is put in again, the above operation is repeated to achieve a quick installation and removal process.
[0060] In some embodiments, the lower periphery of the reservoir 2 has two opposing slots 12. The locking mechanism 4 includes two push-button latches 41, with the latch slots 4121 of the two push-button latches 412 facing each other. By providing two push-button latches 41, the reservoir 2 can be locked from opposite sides, preventing the reservoir 2 from being uncontrollably dislodged from the seat cavity 11 and ensuring the locking effect.
[0061] It is understood that the press-fit latch 41 of this application is a conventional device in the prior art. By pressing it, the latch 412 can move downwards and swing inwards to close, while in the position of Figure 4 The lock in the liquid storage tank 2 is shown to be in the closed state. When the latch 41 is pressed again, it moves upward and swings outward to open, thus maintaining its closed position. Figure 5 The diagram shows the open state of the liquid storage tank 2. Therefore, this application does not provide specific details about the structure and operating principle of the press-fit buckle 41.
[0062] In some embodiments, such as Figure 3 As shown, the bottom outer peripheral wall of the liquid storage tank 2 tapers inward and extends downward to form a neck 23, which surrounds the outside of the outlet 21. The outer peripheral edge of the neck 23 extends outward to form a boss 22. The boss 22 can be a continuous ring or a discontinuous ring segment, as long as it can cooperate with the locking groove 4121 to achieve locking or unlocking. The elastic cut valve 3 is located inside the neck 23, and the outer peripheral edge of the elastic cut valve 3 is pressed against the outer peripheral edge of the outlet 21 by the fixing cover 6. The liquid storage tank 2 has a reasonable structural design, which makes it easy to cooperate with the pushing mechanism 5 and the locking mechanism 4 respectively to form a compact structure and reduce the volume.
[0063] The fixing cap 6 can be secured to the bottom of the liquid storage tank 2 via a snap-fit mechanism, thereby sealing the resilient slit valve 3 to the outlet 21. Of course, the fixing method between the fixing cap 6 and the bottom of the liquid storage tank 2 is not limited to snap-fit; for example, it can also be connected by screws. Furthermore, the resilient slit valve 3 can also be installed at the outlet 21 directly using methods such as ultrasound or adhesive.
[0064] In some embodiments, such as Figure 3 and Figure 6 As shown, the top of the liquid storage tank 2 is open and has a cover 24. The cover 24 has at least one slit, i.e., a micro-hole (not shown in the figure), for air to enter. By setting the slit, air can enter the liquid storage tank 2, preventing negative pressure from forming inside the liquid storage tank 2, and facilitating the liquid to smoothly enter the top rod 51 through the elastic cut valve 3 and flow into the spray nozzle or atomizing nozzle of the beauty device.
[0065] This application also provides a beauty device, which includes a handle 7 and an operating head (not shown in the figure) located at one end of the handle 7. The beauty device also includes the liquid storage device in any of the above embodiments. The base 1 of the liquid storage device is fixed in the cavity of the handle 7. When the liquid storage tank 2 of the liquid storage device placed in the handle 7 is pressed down, the locking mechanism 4 releases the liquid storage tank 2. The liquid storage tank 2 pops up under the action of the pushing mechanism 5 and can maintain the popped-up state. The upper end of the liquid storage tank 2 is exposed outside the other end of the handle 7, that is, the liquid storage tank 2 will be higher than the upper surface of the handle 7, making it convenient for the user to remove the liquid storage tank 2 from the base 1 and the handle 7.
[0066] In the beauty device of this application embodiment, when the liquid storage tank 2 is installed, the liquid storage tank 2 does not need to protrude from the end face of the handle 7, or a notch is provided on the side of the handle 7 to facilitate the removal of the liquid storage tank 2, so that the function of quickly installing and removing the liquid storage tank 2 can be realized while keeping the end face of the whole machine flush and the overall appearance intact.
[0067] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
