Description

Technical Field

[0001] This invention relates to the field of container devices, and more particularly to a liquid storage device. Background Technology

[0002] In the cosmetics and other fields, there are usually issues related to the packaging, transportation, and storage of cosmetics or other fluid products, especially liquid products. Currently, liquid products are usually stored in storage bottles. To facilitate the use of liquid products, a pump is usually installed on the storage bottle, which can quickly pump out the liquid in the storage bottle by pressing the pump.

[0003] However, if the pump is accidentally pressed when the reservoir is not in use, the liquid inside will be discharged, resulting in waste. Summary of the Invention

[0004] In order to overcome at least one of the defects described in the prior art, the present invention provides a liquid storage device for solving the problem of liquid discharge caused by misoperation when the liquid storage bottle is not in use.

[0005] The technical solution adopted by this invention to solve its problem is:

[0006] A liquid storage device includes a liquid storage component, a liquid outlet component, a liquid outlet pump assembly, a sealing component, and an anti-rotation component;

[0007] The sealing component is provided with a liquid flow channel and is located at one end of the liquid storage component. The liquid flow channel is connected to the interior of the liquid storage component. The liquid outlet component is provided with a liquid outlet channel.

[0008] The installation channel is provided with a locking position and an unlocking position. One of the liquid outlet and the sealing member is provided on the anti-rotation member, and the other reciprocates between the locking position and the unlocking position of the installation channel.

[0009] One of the liquid outlet component and the sealing component is disposed on the anti-rotation component, and the other is in a locked and unlocked position in the installation channel;

[0010] The other of the liquid outlet and the sealing member located in the unlocked position moves along the axial direction of the anti-rotation member toward one of the liquid outlet and the liquid storage member under the action of an external force, so as to compress the liquid outlet pump assembly for pumping liquid from the liquid storage member.

[0011] Furthermore, the discharge pump assembly includes a pump body and a squeezing component;

[0012] A pressure through hole is provided on the side wall of the liquid storage component at the end away from the sealing component;

[0013] The extrusion member is disposed in the liquid storage member and abuts against the inner edge of the liquid storage member, so as to divide the interior of the sealing member into two independent chambers at both ends of the extrusion member, and the extrusion member moves between the sealing member and the pressure through hole.

[0014] Furthermore, the liquid outlet is rotatably mounted on the anti-rotation member, and has only one degree of freedom along the circumferential direction of the anti-rotation member;

[0015] At least one guide groove is provided on the inner wall of the end of the installation channel away from the liquid outlet, and the guide groove includes a circumferential locking groove and an axial movement groove.

[0016] The side of the circumferential locking groove away from the liquid outlet is the open side. The axial movement groove is located at one end of the circumferential locking groove and communicates with the circumferential locking groove, and extends along the axial direction of the anti-rotation member.

[0017] At least one guide block is provided on the outer wall of the sealing member. The guide block is disposed in the circumferential locking groove and the axial movement groove. When the guide block is located in the circumferential locking groove, the circumferential locking groove restricts the guide block from moving axially in the anti-rotation member on the side wall of the anti-rotation member in the circumferential direction.

[0018] Furthermore, in the axial direction of the anti-rotation member, the guide block is provided with an anti-rotation groove, wherein:

[0019] The circumferential locking groove is provided with a first anti-rotation bar. The guide block moves along the circumferential locking groove so that the anti-rotation groove engages with the first anti-rotation bar to prevent the guide block from rotating within the circumferential locking groove.

[0020] And / or, the axial movement groove is provided with a second anti-rotation bar, the guide block rotates and moves along the circumferential locking groove so that the anti-rotation groove is engaged with the second anti-rotation bar, and the guide block moves axially in the axial movement groove along the second anti-rotation bar.

[0021] Furthermore, the liquid outlet component includes a rotating base and a liquid outlet nozzle, the liquid outlet channel is disposed on the rotating base, and the liquid outlet nozzle is disposed on the side wall of the rotating base and communicates with the liquid outlet channel;

[0022] Along the axial direction of the rotating seat, multiple guide ridges are provided on the outer wall of the rotating seat, and multiple guide grooves are provided in the sealing member. The rotating seat is inserted into the sealing member, and the guide ridges are slidably disposed in the guide grooves.

[0023] Furthermore, it also includes a limiting shell, on the side wall of which a receiving groove is provided circumferentially, and one end of the limiting shell is connected to the anti-rotation member;

[0024] The rotating seat is fitted and rotatably disposed in the limiting shell, and one end of the liquid outlet passes through the receiving groove and is detachably connected to the rotating seat.

[0025] Furthermore, a hidden compartment is provided at one end of the receiving tank. When the liquid storage device is in the locked state, the liquid outlet is rotated into the hidden compartment to hide the end away from the rotating seat.

[0026] Furthermore, it also includes a force-applying component, wherein at least one force-receiving surface is provided on the outer wall of the force-applying component;

[0027] The limiting shell has an axially arranged through-cavity in the middle, the force-applying component is located at the end of the rotating seat away from the sealing component, and the force-bearing surface is located outside the through-cavity in the limiting shell.

[0028] Furthermore, it also includes a gripping member, which covers the liquid storage member and one end of the gripping member is connected to the anti-rotation member. An external force is applied to the gripping member, and the gripping member is compressed and acts on the liquid storage member to make the liquid storage member move axially in the anti-rotation member.

[0029] Furthermore, the inner wall of the gripping member is provided with a pressure-applying part. When an external force is applied to the gripping member, the pressure-applying part of the gripping member applies to the end of the liquid storage member away from the anti-rotation member.

[0030] And / or, the gripping member is provided with at least one hollowed-out groove; the hollowed-out groove extends from the end of the gripping member away from the anti-rotation member toward the anti-rotation member.

[0031] Furthermore, the liquid storage component is a deformable component. When the gripping component acts on the liquid storage component, the liquid storage component deforms and squeezes the liquid inside the liquid storage component to move towards the liquid outlet component.

[0032] In summary, the liquid storage device provided by the present invention has the following technical effects:

[0033] This invention features a locking and unlocking position in the installation channel. The liquid storage device can be adjusted to the unlocking position when needed and to the locking position after use, effectively preventing liquid dispensing problems caused by misoperation when the liquid storage device is not in use and avoiding waste. Secondly, the locking and unlocking positions of this invention are located in the installation channel, which effectively avoids movement failure caused by external interference when the liquid storage device switches between the two positions.

[0049] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0050] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0051] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0052] See Figure 1 and Figure 2This invention discloses a liquid storage device, including a liquid storage component 10, a liquid outlet component 20, a liquid outlet pump assembly 30, a sealing component 40, and an anti-rotation component 50. The sealing component 40 is provided with a liquid flow channel and is located at one end of the liquid storage component 10, the liquid flow channel communicating with the interior of the liquid storage component 10. The liquid outlet component 20 is provided with a liquid outlet channel. The anti-rotation component 50 is provided with an installation channel 51, the liquid outlet component 20 and the liquid storage component 10 are each located at one end of the installation channel 51, and the liquid flow channel and the liquid outlet channel are connected by a liquid outlet pump assembly. The liquid pump assembly 30 is connected; the mounting channel 51 is provided with a locking position and an unlocking position, one of the liquid outlet 20 and the sealing member 40 is disposed on the anti-rotation member 50, and the other reciprocates between the locking position and the unlocking position of the mounting channel 51; the other of the liquid outlet 20 and the sealing member 40 located in the unlocking position moves along the axial direction of the anti-rotation member 50 towards one of the liquid outlet 20 and the liquid storage member 10 under the action of external force, so as to compress the liquid pump assembly 30 for pumping liquid from the liquid storage member 10.

[0053] The liquid storage container 10 can be a common cylindrical bottle, with one end open and the other end round. A sealing element 40 is installed at the opening of the liquid storage container 10. To facilitate liquid dispensing from the container 10, a liquid flow channel is provided on the sealing element 40. Specifically, the liquid flow channel extends axially along the sealing element 40 to connect to the interior of the liquid storage container 10. Furthermore, the sealing element 40 and the liquid storage container 10 are detachably connected to facilitate the replenishment of liquid into the container 10. For example, the lower end of the sealing element 40 is inserted into the liquid storage container 10, and a sealing ring is provided between the lower end of the sealing element 40 and the inner wall of the liquid storage container 10 to prevent liquid leakage.

[0054] See Figure 3 The anti-rotation member 50 has a through cavity in the axial direction to form an installation channel. For ease of description, this embodiment uses the anti-rotation member 50 as the reference for orientation description.

[0055] The liquid outlet component 20 can be an existing cap with a liquid outlet nozzle. The liquid outlet component 20 is provided with a liquid outlet channel, which is connected to the liquid outlet nozzle.

[0056] Optional, see below Figure 4The liquid outlet 20 is rotatably mounted on the anti-rotation member 50 and has only one degree of freedom along the circumference of the anti-rotation member 50. At least one guide groove 510 is provided on the inner wall of the end of the installation channel 51 away from the liquid outlet 20. The guide groove 510 includes a circumferential locking groove 511 and an axial movement groove 512. The side of the circumferential locking groove 511 away from the liquid outlet 20 is an open side. The axial movement groove 512 is provided at one end of the circumferential locking groove 511 and communicates with the circumferential locking groove 511, and extends along the axial direction of the anti-rotation member 50. At least one guide block 41 is provided on the outer wall of the sealing member 40. The guide block 41 is mounted on the circumferential locking groove 511 and the axial movement groove 512. When the guide block 41 is located in the circumferential locking groove 511, the circumferential locking groove 511 restricts the guide block 41 from moving in the axial direction of the anti-rotation member 50 on the side wall of the anti-rotation member 50.

[0057] The liquid outlet 20 is positioned at the top of the anti-rotation member 50. The lower end of the liquid outlet 20 is rotatably positioned within the installation channel 51. For example, the upper part of the installation channel 51 has two parallel annular limiting protrusions, and correspondingly, the outer wall of the liquid outlet 20 has a rotating protrusion. When the liquid outlet 20 is installed in the installation channel 51, the rotating protrusion engages between the two annular limiting protrusions, thus allowing the liquid outlet 20 to rotate only circumferentially within the anti-rotation member 50. The sealing member 40 is located below the anti-rotation member 50, and the upper end of the anti-rotation member 50 is fitted onto the lower part of the installation channel.

[0058] Optional, see below Figure 9 The liquid pump assembly 30 includes a pump body 31 and a squeezing member 32; a pressure through hole 90 is provided on the side wall of the liquid storage member 10 at the end away from the sealing member 40; the squeezing member 32 is disposed in the liquid storage member 10 and abuts against the inner edge of the liquid storage member 10, so as to divide the interior of the sealing member 40 into two independent chambers at both ends of the squeezing member 32, and the squeezing member 32 moves between the sealing member 40 and the pressure through hole 90.

[0059] The pump body 31 is positioned between the liquid outlet 20 and the anti-rotation member 50. The upper and lower ends of the pump body 31 are connected to the liquid outlet 20 and the anti-rotation member 50 respectively, connecting the liquid flow channel and the liquid outlet channel. At this time, the pump body 31 is located in the installation channel 51. According to existing technology, the pump body 31 is pressurized to achieve pressure pumping, and has a reverse recovery function after the pressure is removed. In this embodiment, under the action of external force, the liquid outlet 20 and the sealing member 40 move closer together, and the pump body 31 is pressurized to pump the liquid in the storage container 10. When the external force is removed, the pump body 31 provides a reverse force (generally an elastic force), and the liquid outlet 20 and the sealing member 40 move away from each other and return to their original positions.

[0060] For example, the extruder 32 is preferably a piston, which is adapted to the inner wall of the liquid reservoir 10. It is understood that the piston is tightly fitted to the inner wall of the liquid reservoir 10. The top of the piston is the upper chamber inside the liquid reservoir 10, and the bottom is the lower chamber. The upper and lower chambers are not interconnected. At least one (preferably two) pressure through-holes 90 are provided at the bottom of the liquid reservoir 10.

[0061] Preferably, the discharge pump assembly 30 is installed in the liquid passage of the sealing member 40. During installation, the lower end of the discharge passage of the discharge member 20 is inserted into the top end of the pump body 31, thereby completing the connection between the discharge member 20, the pump body 31, and the sealing member 40. It can be imagined that if the pump body 31 is installed in the discharge passage of the discharge member 20, then during installation, the lower end of the pump body 31 is inserted into the top end of the liquid passage.

[0062] The key feature of this embodiment is that a guide groove 510 is provided in the installation channel 51, and the circumferential locking groove 511 and the axial movement groove 512 are rectangular grooves. The circumferential locking groove 511 is provided along the lower edge of the installation channel 51, so the lower side of the circumferential locking groove 511 is an open side. The axial movement groove 512 extends upward and does not penetrate the top of the inner wall of the installation channel 51. The circumferential locking groove 511 and the axial movement groove 512 are connected to form an L-shaped structure.

[0063] The sealing component 40 is equipped with a guide block 41 that is adapted to the circumferential locking groove 511 and the axial movement groove 512. The circumferential locking groove 511 forms the locking position of the aforementioned mounting channel 51, which can be understood as the upper edge of the circumferential locking groove 511 restricting the degree of freedom of the guide block 41 to move upward; the axial movement groove 512 forms the unlocking position of the aforementioned mounting channel 51, which can be understood as the guide block 41 being able to move up and down along the axial movement groove 512 when it is in the axial movement groove 512. In general, in the initial state, the guide block 41 is located in the circumferential locking groove 511, and the liquid storage device is in a non-use state. Since the liquid outlet 20 only has the axial direction of freedom, the sealing member 40 in the circumferential locking groove 511 is restricted from moving towards the liquid outlet 20. The sealing member 40 cannot move towards the liquid outlet 20 and squeeze the pump body 31. Therefore, at this time, the liquid outlet device of the present invention better avoids the problem of liquid outlet caused by misoperation. At this time, the squeezing member 32 is close to the bottom of the liquid storage device 10. The upper chamber has the largest space and is filled with liquid. Its interior is similar to a vacuum. The lower chamber has the smallest space and is connected to the outside through the pressure through hole 90. When it is necessary to pump the liquid in the storage container 10, the sealing member 40 is rotated (the liquid outlet 20 rotates synchronously) so that the guide block 41 enters the axial movement groove 512 from the circumferential locking groove 511 (at this time, it is in the unlocked state). At this time, an external force is applied to the storage container 10, and the storage container 10 pushes the sealing member 40 upward to move synchronously. The guide block 41 moves in the axial movement groove 512, and the sealing member 40 approaches the liquid outlet 20 and squeezes the pump body 31. The pump body 31 pumps the liquid in the storage container 10 sequentially from the liquid flow channel, the liquid outlet channel, and the liquid outlet nozzle. During extrusion, as some of the liquid in the upper chamber is pumped out, the air pressure in the upper chamber is lower than the atmospheric pressure in the lower chamber. At this time, the extruder 32 moves upward under the pressure of atmospheric pressure from bottom to top. As a result, the space in the upper chamber decreases and the space in the lower chamber increases until all the liquid in the upper chamber is pumped out. After the pumping is completed, the external force on the liquid storage component 10 is released. Under the reverse force of the pump body 31, the sealing component 40 moves downward. After the pump body 31 returns to its initial state, the sealing component 40 is rotated so that the guide block 41 enters the circumferential locking groove 511 (at this time, it is in the locked state).

[0064] Furthermore, regarding the number of guide grooves 510, it is preferable to have two guide grooves 510, which are symmetrically arranged around the axis of the anti-rotation component 50. Correspondingly, there are two guide blocks 41, with one guide block 41 corresponding to one guide groove 510. In this way, the two guide blocks 41 guide the sealing component 40, making its movement within the guide grooves 510 more stable.

[0065] Other feasible solutions include: the sealing member 40 is rotatably disposed at the lower part of the installation channel 51, and has only one degree of freedom along the circumference of the anti-rotation member 50. In this case, the circumferential locking groove 511 of the guide groove 510 is disposed at the upper edge of the installation channel 51, and the axial movement groove 512 extends downward. The guide block 41 is disposed on the outer wall of the liquid outlet member 20 and disposed in the guide groove 510. In this embodiment, the external force is applied to the liquid outlet member 20, and the liquid outlet member 20 moves downward and pressurizes the pump body 31.

[0066] In the above embodiments, one of the liquid outlet component 20 and the sealing component 40 is rotatably mounted in the installation channel 51, and this component has only one degree of freedom along the circumferential direction of the anti-rotation component 50. That is, when one of them rotates along the circumferential locking groove 511, the other one also rotates (i.e., both ends of the pump body 31 are fixedly connected to the liquid outlet component 20 and the sealing component 40 respectively). The difference in this embodiment is that one of the liquid outlet component 20 and the sealing component 40 is fixedly mounted in the installation channel 51, and the other is provided with a pump body 31, which is rotatably connected to the aforementioned component. Thus, when the other component in this embodiment rotates in the circumferential locking groove 511, the other component does not need to rotate accordingly.

[0067] Other issues mentioned above include how to replenish the liquid after all the liquid in the reservoir 10 has been pumped out. Specifically, first, remove the sealing member 40, then manually push the squeezing member 32 downwards in the reservoir 10 until it returns to its initial state. Next, replenish the reservoir 10 with new liquid, and then seal the sealing member 40 to the end of the reservoir 10.

[0068] Alternatively, in this embodiment, the liquid pump assembly 30 can also be replaced with an existing press pump and a conduit connected to the press pump. The press pump is connected to the pump body 31 and each component. The difference is that the conduit is located at the lower end of the press pump and extends into the liquid storage container 10. In this case, the liquid storage container 10 eliminates the squeezing member 32 and the pressure through hole 90.

[0069] Optionally, in the axial direction of the anti-rotation member 50, the guide block 41 is provided with an anti-rotation groove 411, wherein: the circumferential locking groove 511 is provided with a first anti-rotation bar 5111, and the guide block 41 moves along the circumferential locking groove 511 so that the anti-rotation groove 411 is engaged with the first anti-rotation bar 5111 to prevent the guide block 41 from rotating within the circumferential locking groove 511; and / or, the axial movement groove 512 is provided with a second anti-rotation bar 5121, and the guide block 41 rotates and moves along the circumferential locking groove 511 so that the anti-rotation groove 411 is engaged with the second anti-rotation bar 5121, and the guide block 41 moves axially along the second anti-rotation bar 5121 in the axial movement groove 512.

[0070] As can be seen from the foregoing, the guide block 41 will reciprocate between the circumferential locking groove 511 and the axial movement groove 512. Therefore, the key is the confirmation position of the guide block 41 in the circumferential locking groove 511 and the axial movement groove 512. It can be understood that the focus of this embodiment is on how to determine whether the guide block 41 has entered the circumferential locking groove 511 or the axial movement groove 512.

[0071] For example, along the circumferential direction of the circumferential locking groove 511, the first anti-rotation bar 5111 is positioned at the middle of the circumferential locking groove 511. In the aforementioned initial state, the first anti-rotation bar 5111 is engaged in the anti-rotation groove 411. Under the rotation of the sealing member 40 by external force, the first anti-rotation bar 5111 disengages from the anti-rotation groove 411, and the guide block 41 moves towards the axial movement groove 512. Then, the anti-rotation groove 411 engages with the second anti-rotation bar 5121. At this point, it is clear that the guide block 41 is fully inserted into the axial movement groove 512, and the sealing member 40 moves axially in the anti-rotation member 50. Thus, the placement of the first anti-rotation bar 5111 and the second anti-rotation bar 5121 can indicate the position of the guide block 41, so as to confirm whether the liquid storage device is in a locked or unlocked state. In addition, the first anti-rotation bar 5111 and the second anti-rotation bar 5121 can be set as separate solutions or as a single solution.

[0072] In the above scheme, the first anti-rotation strip 5111 and the second anti-rotation strip 5121 can be replaced by anti-rotation protrusions.

[0073] Optionally, the liquid outlet component 20 includes a rotating seat 21 and a liquid outlet nozzle 22. The liquid outlet channel is disposed on the rotating seat 21, and the liquid outlet nozzle 22 is disposed on the side wall of the rotating seat 21 and communicates with the liquid outlet channel. Along the axial direction of the rotating seat 21, multiple guide ridges 211 are provided on the outer wall of the rotating seat 21, and multiple guide grooves 412 are provided in the sealing component 40. The rotating seat 21 is inserted into the sealing component 40, and the guide ridges 211 are slidably disposed in the guide grooves 412.

[0074] In this embodiment, the aforementioned liquid outlet 20 and sealing member 40 move towards or away from each other, previously connected only by the pump body 31. In this embodiment, the sealing member 40 has an insertion groove at its top, and multiple guide grooves 412 are arranged axially along the inner wall of the insertion groove. Multiple guide protrusions 211 on the outer wall of the rotating seat 21 and multiple guide grooves 412 in the insertion groove of the anti-rotation member 50 are fitted one-to-one, and the guide protrusions 211 and guide grooves 412 slide against each other, providing guidance for the movement of the sealing member 40 towards the liquid outlet 20, thus improving the stability of the sealing member 40's movement. Furthermore, the liquid outlet 22 in this embodiment is located on the side wall of the rotating seat 21, thereby leaving the end face of the rotating seat 21 away from the liquid storage member 10 unsupported. When the liquid storage member 10 needs to move towards the liquid outlet 20 to squeeze out liquid, the aforementioned end face of the rotating seat 21 can be used as a support surface, and the hand can rest against this support surface to ensure that the liquid storage member 10 squeezes the pump body 31. In addition, besides having a guiding function in the axial direction, the guide ridge 211 and guide groove 412 can also interact in the circumferential direction when the sealing member 40 is rotated, thereby driving the rotation of the rotating seat 21.

[0075] Optional, see 5- Figure 8 It also includes a limiting shell 60, a receiving groove 61 is provided circumferentially on the side wall of the limiting shell 60, and one end of the limiting shell 60 is connected to the anti-rotation member 50; the rotating seat 21 is sleeved and rotatably disposed in the limiting shell 60, and one end of the liquid outlet 22 passes through the receiving groove 61 and is detachably connected to the rotating seat 21.

[0076] In conjunction with the aforementioned embodiment of the circumferential movement of the liquid outlet 20 relative to the anti-rotation member 50, this embodiment provides another method for the rotatable connection between the liquid outlet 20 and the anti-rotation member 50. Specifically, a limiting groove is provided in the middle of the limiting shell 60, the rotating seat 21 is sleeved in the limiting groove, and the receiving groove 61 is provided through the side wall of the limiting groove. The liquid outlet 22 passes through the receiving groove 61 and connects to the rotating seat 21, thus limiting the axial direction of the rotating seat 21. This prevents the rotating seat 21 from moving axially when the liquid storage member 10 squeezes towards the rotating seat 21, ensuring the completion of the liquid extrusion action. It should also be noted that at this time, it is only necessary to hold the limiting shell 60. Of course, the receiving groove 61 can provide space for the movement of the liquid outlet 22 in the circumferential direction, so the rotating seat 21 can also meet the aforementioned function of synchronous rotation of the neutralizing and sealing member 40.

[0077] Preferably, the dispensing nozzle 22 and the rotating seat 21 are installed by a plug-in connection, with the key point being that a sealing ring is fitted on the dispensing nozzle 22 to prevent leakage.

[0078] Preferably, the limiting shell 60 and the anti-rotation member 50 are connected by the inner wall of the limiting groove engaging with the outer wall of the anti-rotation member 50. Specifically, the engaging method can be a combination of a protrusion and a groove, which is simple in structure and easy to assemble.

[0079] In addition, the outer contour of the limiting shell 60 is elliptical, and the wall thickness of the limiting shell 60 decreases from the short half axis to the long half axis. A receiving groove 61 is provided on one side of the short half axis of the limiting shell 60.

[0080] Furthermore, as mentioned above, the dispensing nozzle 22 is used to prevent the rotating seat 21 from moving axially. The contact surface between the dispensing nozzle 22 and the receiving groove 61 is limited. Therefore, in order to better restrict the axial movement of the rotating seat 21 when the liquid storage component 10 is squeezed upward, a protrusion is provided on the inner wall of the limiting groove. The protrusion can be a block or a convex ring 62. Taking the convex ring 62 as an example, an abutting part is provided on the middle of the outer wall of the rotating seat 21. Preferably, the abutting part has multiple abutting ridges 213 spaced apart. When the rotating seat 21 is installed into the limiting groove, the upper part of the rotating seat 21 passes through the convex ring 62, and the dispensing nozzle 22 is inserted into the upper part of the rotating seat 21. At this time, the abutting ridges 213 abut against the bottom surface of the convex ring 62. Thus, the abutting ridges 213 and the dispensing nozzle 22 are respectively located on the upper and lower sides of the convex ring 62, which better restricts the axial movement of the rotating seat 21.

[0081] Optionally, a hidden compartment 611 is provided at one end of the receiving tank 61. When the liquid storage device is in the locked state, the liquid outlet 22 rotates into the hidden compartment 611 to hide the end away from the rotating seat 21.

[0082] The liquid storage device has locked and unlocked states. It should be noted that when the liquid storage device switches between locked and unlocked states, the dispensing nozzle 22 rotates from one end of the receiving groove 61 to the other. When the liquid storage device is in the locked state, the corresponding end of the receiving groove 61 where the dispensing nozzle 22 is located is in a closed position. When the liquid storage device is in the unlocked state, the corresponding end of the receiving groove 61 where the dispensing nozzle 22 is located is in an open position. This embodiment emphasizes that when the dispensing nozzle 22 is in the closed position, the end of the dispensing nozzle 22 away from the rotating seat 21 is hidden in the hiding chamber 611 (the limiting shell 60 has more accommodating space in the long half-axis direction, so the dispensing nozzle 22 is exposed on the short half-axis and hidden when turning to the long half-axis). Specifically, the receiving tank 61 is provided with a protruding shielding wall at the corresponding closed position. The outer end of the liquid outlet 22 located at the closed position is blocked by the shielding wall. Since the liquid storage device is in a non-use state at this time, the hidden compartment 611 provides shielding protection for the liquid outlet 22 to prevent external dust and other pollutants from entering the liquid outlet 22.

[0083] Optional, see below Figures 10-13It also includes a force-applying component 70, and at least one force-bearing surface 71 is provided on the outer wall of the force-applying component 70; the middle part of the limiting shell 60 is an axially arranged through cavity, the force-applying component 70 is provided at the end of the rotating seat 21 away from the sealing component 40, and the force-bearing surface 71 is located outside the through cavity in the limiting shell 60.

[0084] In this embodiment, the force-applying component 70 is used to drive the rotation of the rotating seat 21. The force-applying component 70 is a cap used as a top cover for the cavity, which is fastened to the top of the cavity and connected to the rotating seat 21. As mentioned above, the liquid storage device is driven to switch between the locked and unlocked states by rotating the sealing component 40. However, as can be seen from the above, the upper end of the sealing component 40 is located in the mounting channel of the anti-rotation component 50, and the lower end of the anti-rotation component 50 is connected to the liquid storage component 10, so operating the sealing component 40 is inconvenient. In this embodiment, a force-applying component 70 is provided. The force-applying component 70 is connected to the upper end of the rotating seat 21, and its top end extends outward to the outside of the cavity. When it is necessary to switch between the locked and unlocked states, it is more convenient and faster to operate the extended force-applying component 70. Furthermore, in this embodiment, to better rotate the force-applying member 70, at least one force-receiving surface 71 is provided on the top edge of the force-applying member 70. This number can be set as needed. The force-receiving surface 71 can be a plane or a concave surface, the purpose of which is to enhance the convenience of hand grip and increase the friction of rotation. Preferably, in this embodiment, two force-receiving surfaces 71 are arranged symmetrically around the center of the force-applying member 70.

[0085] Alternatively, the connection between the force-applying component 70 and the rotating seat 21 can be configured such that an outer frustum 214 is provided on the upper side of the rotating seat 21, and the aforementioned abutment ridge 213 is provided on the side wall of the outer frustum 214. Importantly, in the axial direction of the anti-rotation component 50, the outer frustum 214 is provided with at least two connecting through holes 2141 that are symmetrical about the center of the outer frustum 214. At least two fastening blocks 72 are provided below the force-applying component 70. The fastening block 72 includes an extension block 721 and a snap-fit ​​protrusion 722. One end of the extension block 721 is provided at the edge of the force-applying component 70, and the other end extends along the axial direction of the force-applying component 70. The snap-fit ​​protrusion 722 is provided on the inner side of the other end of the extension block 721. It should be noted that the extension block 721 has a certain elasticity. When the force-applying component 70 is installed on the rotating seat 21 from top to bottom, the inner side of the snap-fit ​​protrusion 722 abuts against the inner side of the connecting through hole 2141. The extension block 721 is pushed outward and deforms, pushing the force-applying component 70 downward. After the snap-fit ​​protrusion 722 passes through the connecting through hole 2141, the extension block 721 returns to its original position, and the snap-fit ​​protrusion 722 engages with the bottom of the connecting through hole 2141. In addition, in order to facilitate the insertion of the buckle protrusion 722 into the connecting through hole 2141, the lower end of the inner side of the buckle protrusion 722 is provided with an inclined surface that slopes from bottom to top and from outside to inside. This inclined surface is used to abut against the inner side of the connecting through hole 2141. The abutment of the inclined surface is less likely to cause jamming or stuck abutment.

[0086] Furthermore, the lower edge of the force-applying component 70 is provided with a snap-fit ​​notch 73. When the force-applying component 70 is snapped and installed on the top of the rotating seat 21, the snap-fit ​​notch 73 snaps onto the liquid outlet 22 from top to bottom. In this way, when the force-applying component 70 is rotated, the force-applying component 70 can better drive the liquid outlet 22 to move together.

[0087] Optionally, it also includes a gripper 80, which covers the liquid reservoir 10 and one end of the gripper 80 is connected to the anti-rotation member 50. When an external force is applied to the gripper 80, the gripper 80 is compressed and acts on the liquid reservoir 10, so that the liquid reservoir 10 moves axially in the anti-rotation member 50.

[0088] The gripper 80 has a through-hole structure in the middle. The connection between the gripper 80 and the anti-rotation member 50 can be referenced from the connection method between the limiting shell 60 and the anti-rotation member 50, which will not be repeated here. Specifically, in order to enable the limiting shell 60 and the gripper 80 to be axially positioned on the anti-rotation member 50, a positioning protrusion ring 52 is preferably provided in the middle of the outer wall of the anti-rotation member 50. The lower end of the limiting shell 60 and the upper end of the gripper 80 respectively abut against the top and bottom surfaces of the positioning protrusion ring 52.

[0089] The key feature of this embodiment is that the gripper 80 is elastic. When the liquid storage device is in the unlocked state, the gripper 80 is pressed inward by force, and the gripper 80 acts on the liquid storage member 10, causing the liquid storage member 10 to move closer to the liquid outlet 20 (i.e., move upward) to squeeze out liquid. When the gripper 80 is released, the gripper 80 returns to its elasticity, and the liquid storage member 10 moves away from the liquid outlet 20 (i.e., move downward). When the liquid storage member 10 descends to its lowest position, the liquid storage device can be switched to the locked state.

[0090] Optionally, the inner wall of the grip 80 is provided with a pressure-applying part 82. When an external force is applied to the grip 80, the pressure-applying part 82 of the grip 80 applies to the end of the liquid reservoir 10 away from the anti-rotation member 50; and / or, the grip 80 is provided with at least one hollow groove 81; the hollow groove 81 extends from the end of the grip 80 away from the anti-rotation member 50 toward the anti-rotation member 50.

[0091] In this embodiment, the two options for the pressure application part 82 and the hollow groove 81 can be implemented separately or set simultaneously.

[0092] The pressure-applying part 82 is a pressure-applying protrusion provided on the hollow inner wall of the grip 80. When the grip 80 is squeezed inward, the pressure-applying protrusion is used to abut against and push the liquid storage part 10 to move upward.

[0093] In addition, the inner side of the pressure protrusion is configured as a pressure surface adapted to the bottom of the liquid storage component 10. The pressure surface is adapted to abut against the bottom of the liquid storage component 10. The increased contact area between the two is more conducive to the smooth pushing of the pressure protrusion onto the liquid storage component 10. For example, if the liquid storage component 10 mentioned above has a round bottom, then the pressure surface in this embodiment can be configured as a matching arc shape. Alternatively, the pressure surface is an inclined surface of the pressure protrusion from bottom to top and from the inside to the outside, that is, the pressure protrusion has a structure that is smaller at the top and larger at the bottom. The actual consideration for this structure is that when the gripper 80 is pressed, its lower end deforms more. The fact that the lower part of the pressure protrusion is larger than the upper part can better support and squeeze the bottom of the liquid storage component 10.

[0094] Furthermore, the aforementioned gripper 80 will be compressed against the liquid reservoir 10. In this embodiment, in order to give the gripper more deformation, the gripper 80 is provided with a hollow groove 81. Therefore, the function of the hollow groove 81 is to provide more space for the gripper 80 to deform, which is conducive to the gripper 80 squeezing inward and ensuring that the liquid reservoir 10 has sufficient squeezing stroke in the axial direction.

[0095] In this embodiment, the hollow groove 81 is a strip-shaped groove; preferably, the hollow groove 81 can be configured with a structure that is smaller at the top and larger at the bottom. The significance of this structure is that when actually pressing the grip 80, its bottom end can be pressed. The upper part of the hollow groove 81 is smaller, thus the upper part has greater rigidity, which can serve as a force-bearing point, making it easier to press the lower end of the grip 80. In addition, the number of the above-mentioned hollow grooves 81 can be one, but it is preferred that there are two hollow grooves 81 that are symmetrical about the center of the grip 80. The two hollow grooves 81 can better balance and absorb the deformation on both sides of the grip 80.

[0096] Furthermore, in conjunction with the above, the outer contour of the gripper 80 can be designed as an ellipse, referencing the limiting shell 60, to achieve unity and improve the aesthetics. Additionally, the perforated groove 81 can be located on the sidewall near the shorter side, meaning the width of the perforated groove 81 is set along the longer side. This provides greater flexibility in setting the width of the perforated groove 81, allowing for more space for compression towards the center, which is more conducive to the pressure applied by the pressure unit 82 on the liquid reservoir 10.

[0097] Optionally, the liquid storage component 10 is a deformable component. When the gripping component 80 acts on the liquid storage component 10, the liquid storage component 10 deforms and squeezes the liquid inside the liquid storage component 10 to move towards the liquid outlet component 20.

[0098] In this embodiment, the aforementioned squeezing member 32 can move axially in the liquid storage member 10. However, unlike the previous embodiment, the liquid storage member 10 is deformable. When the gripper 80 squeezes the liquid storage member 10 inward, the liquid storage member 10 moves upward while its bottom is also deformed by pressure. This bottom deformation compresses the squeezing member 32 inside the liquid storage member 10, causing the squeezing member 32 to move upward within the liquid storage member 10. This further pushes the liquid out of the liquid storage member 10, improving the outflow efficiency. Of course, after releasing the pressure on the gripper 80, the liquid storage member 10 not only moves downward but also rebounds and expands.

[0099] In summary, the overall working principle of the liquid storage device is described here:

[0100] Initially, the liquid storage device is locked, and the dispensing nozzle 22 is located in the concealed compartment 611. First, the liquid storage device is rotated by the force-applying member 70 to the unlocked state. At this time, the dispensing nozzle 22 rotates out of the concealed compartment 611 to the open position. The specific locking and unlocking operations are described above and will not be repeated here. Grasp the lower end of the gripper 80 and press inward. The pressure-applying part 82 acts on the bottom of the liquid storage device 10, causing the liquid storage device 10 to move axially upward. The pump body 31 is pressurized to deliver the liquid in the liquid storage device 10 to the dispensing member 20, and the liquid is finally discharged from the dispensing nozzle 22. Additionally, if the liquid storage device 10 is deformable, this is accompanied by the compression deformation of the liquid storage device 10 and the upward movement of the pressure member 32; please refer to the previous description for details.

[0101] Next, if the pressure on the lower end of the gripper 80 is released, the pump body 31 will return to its original position and push the liquid reservoir 10 back to its lowest position. At this time, the liquid reservoir 10 may also expand and recover. Finally, the force application device 70 will once again turn the open nozzle 22 into the hidden chamber 611, and at the same time, the liquid reservoir device will change from the unlocked state to the locked state.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
