The terms used in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0052] Reference is made to Figure 1 and Figure 2The utility model discloses a kind of liquid storage devices, including liquid storage 10, liquid outlet 20, liquid outlet pump assembly 30, sealing element 40 and rotation-stopping element 50;Sealing element 40 is provided with liquid channel, and it is set in one end of liquid storage 10, liquid channel is communicated in the inside of liquid storage 10, and liquid outlet 20 is provided with liquid outlet channel;Rotation-stopping element 50 is provided with installation channel 51, and liquid outlet 20 and liquid storage 10 are respectively located one end of installation channel 51, and liquid channel and liquid outlet channel are communicated by liquid outlet pump assembly 30;Locking position and unlocking position are provided in installation channel 51, one of liquid outlet 20 and sealing element 40 is set on rotation-stopping element 50, and the other reciprocates between locking position and unlocking position of installation channel 51;Another in liquid outlet 20 and sealing element 40 in unlocking position, under the action of external force, it moves along the axial direction of rotation-stopping element 50 and approaches one of liquid outlet 20 and liquid storage 10, to compress liquid outlet pump assembly 30 for pumping the liquid in liquid storage 10.

[0053] Wherein, liquid storage 10 can be selected as common cylindrical bottle body, one end of cylindrical bottle body is open, and the other end is circular structure.Sealing element 40 is sealingly arranged at the opening of liquid storage 10, and of course, to meet the liquid outlet of liquid storage 10, sealing element 40 is provided with liquid channel, specifically, liquid channel is axially through the sealing element 40 and is used to communicate the inside of liquid storage 10.In addition, sealing element 40 and liquid storage 10 are detachably connected, so as to facilitate supplementing liquid into liquid storage 10;For example, the lower end of sealing element 40 is inserted into liquid storage 10, and a sealing ring is arranged between the lower end of sealing element 40 and the inner wall of liquid storage 10 to prevent liquid leakage.

[0054] Referring to Figure 3 Rotation-stopping element 50 is provided with through cavity in the axial direction to form installation channel, in order to facilitate description, the embodiment is described with reference to the orientation of rotation-stopping element 50.

[0055] Liquid outlet 20 can be selected as existing cover with liquid outlet nozzle, and liquid outlet channel is arranged in liquid outlet 20, and it can be known that liquid outlet channel communicates liquid outlet nozzle.

[0056] Optionally, referring to Figure 4The liquid outlet piece 20 is rotationally arranged on the rotation-stopping piece 50, and has only one degree of freedom along the circumferential direction of the rotation-stopping piece 50. At least one guide groove 510 is arranged on the inner wall of the end of the mounting channel 51 away from the liquid outlet piece 20. The guide groove 510 comprises a circumferential locking groove 511 and an axial movement groove 512. The circumferential locking groove 511 is open on the side away from the liquid outlet piece 20. The axial movement groove 512 is arranged 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 rotation-stopping piece 50. At least one guide block 41 is arranged on the outer wall of the sealing piece 40, and the guide block 41 is arranged to run in 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 limits the movement of the guide block 41 in the axial direction of the rotation-stopping piece 50 by the side wall of the rotation-stopping piece 50 in the circumferential direction.

[0057] The liquid outlet piece 20 is arranged on the top of the rotation-stopping piece 50. In addition, the lower end of the liquid outlet piece 20 is rotationally arranged in the mounting channel 51. For example, the upper part of the mounting channel 51 is provided with two annular limiting protrusions parallel to each other. Correspondingly, a rotating protrusion is arranged on the outer side wall of the liquid outlet piece 20. When the liquid outlet piece 20 is installed in the mounting channel 51, the rotating protrusion is clamped between the two annular limiting protrusions. In this way, the liquid outlet piece 20 can only rotate in the circumferential direction of the rotation-stopping piece 50. The sealing piece 40 is located below the rotation-stopping piece 50, and the upper end of the rotation-stopping piece 50 is sleeved on the lower part of the mounting channel.

[0058] Optionally, referring to Figure 9 The liquid outlet pump assembly 30 comprises a pump body 31 and a pressing piece 32. A pressure through hole 90 is arranged on the side wall of the liquid storage piece 10 away from the sealing piece 40. The pressing piece 32 is arranged in the liquid storage piece 10 and abuts against the inner edge of the liquid storage piece 10, so as to divide the inside of the sealing piece 40 into two independent chambers at the two ends of the pressing piece 32. The pressing piece 32 moves between the sealing piece 40 and the pressure through hole 90.

[0059] The pump body 31 is arranged between the liquid outlet piece 20 and the rotation-stopping piece 50. The upper and lower ends of the pump body 31 are respectively connected to the liquid outlet piece 20 and the rotation-stopping piece 50, and the liquid passage and the liquid outlet passage are communicated. At this time, the pump body 31 is located in the mounting channel 51. According to the prior art, it can be known that the pump body 31 is pressed to realize pressure pumping, and has a reverse recovery function after the pressure is removed. In combination with the present embodiment, under the action of an external force, the liquid outlet piece 20 and the sealing piece 40 approach each other, the pump body 31 is pressed to pump the liquid in the liquid storage piece 10. After the external force is removed, the pump body 31 provides a reverse force (generally a spring force), and the liquid outlet piece 20 and the sealing piece 40 move away from each other and return to the original position.

[0060] For example, the extrusion member 32 is preferably a piston which is adapted to the inner wall of the liquid storage member 10. It is appreciated that the piston is tightly fitted to the inner wall of the liquid storage member 10, the top of the piston is the upper chamber inside the liquid storage member 10, and the bottom is the lower chamber. The at least one (preferably two) pressure through holes 90 are arranged at the bottom of the liquid storage member 10.

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

[0062] The embodiment focuses on the installation passage 51, which is provided with a guide groove 510, a circumferential locking groove 511 and an axial movement groove 512. The circumferential locking groove 511 is arranged along the lower edge of the installation passage 51, so the lower side of the circumferential locking groove 511 is open. The axial movement groove 512 extends upward and does not penetrate the top of the inner wall of the installation passage 51. The circumferential locking groove 511 and the axial movement groove 512 are connected to form an L-shaped structure.

[0063] The guide block 41 is provided with a circumferential locking groove 511 and an axial movement groove 512. The circumferential locking groove 511 forms a locking position of the aforementioned installation channel 51, and can be understood as that the upper edge of the circumferential locking groove 511 limits the upward movement freedom of the guide block 41; the axial movement groove 512 forms an unlocking position of the aforementioned installation channel 51, and can be understood as that when the guide block 41 is in the axial movement groove 512, the guide block 41 can reciprocate up and down along 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 piece 20 has only the axial direction freedom, the sealing piece 40 in the circumferential locking groove 511 is limited in the freedom of movement towards the liquid outlet piece 20, and the sealing piece 40 cannot move towards the liquid outlet piece 20 and press the pump body 31, so that the liquid outlet device of the utility model avoids the problem of liquid outlet caused by misoperation. At this time, the pressing piece 32 is close to the bottom of the liquid storage piece 10, the space of the upper chamber is maximum and filled with liquid, and the inside is similar to a vacuum. The space of the lower chamber is minimum, and the lower chamber is communicated with the outside through the pressure through hole 90. When the liquid in the liquid storage piece 10 needs to be pumped, the sealing piece 40 is rotated (the liquid outlet piece 20 is synchronously rotated) to make the guide block 41 enter the axial movement groove 512 from the circumferential locking groove 511 (at this time, it is in an unlocking state). At this time, an external force acts on the liquid storage piece 10, the liquid storage piece 10 pushes the sealing piece 40 to move upwards synchronously, the guide block 41 moves in the axial movement groove 512, the sealing piece 40 approaches the liquid outlet piece 20 and presses the pump body 31, and the pump body 31 extrudes the liquid in the liquid storage piece 10 in turn from the liquid passing channel, the liquid outlet channel and the liquid outlet nozzle. Since the liquid in the upper chamber is partially pumped out, the air pressure in the upper chamber is less than the atmospheric pressure in the lower chamber. At this time, the pressing piece 32 is subjected to the pressure from the bottom to the top of the atmospheric pressure and moves upwards. Thus, the space of the upper chamber is reduced, and the space of the lower chamber is increased, until the liquid in the upper chamber is completely pumped out. After the pumping is completed, the external force on the liquid storage piece 10 is removed, and the sealing piece 40 moves downwards under the reverse force of the pump body 31. After the pump body 31 returns to the initial state, the sealing piece 40 is rotated to make the guide block 41 enter the circumferential locking groove 511 (at this time, it is in a locking state).

[0064] In addition, the number of guide grooves 510 is preferably two, and the two guide grooves 510 are symmetrically arranged about the axis of the rotation stopping piece 50. Correspondingly, the number of guide blocks 41 is two, and one guide block 41 corresponds to one guide groove 510. Thus, the two guide blocks 41 guide the sealing piece 40 to move, so that the movement of the sealing piece 40 in the guide groove 510 is more stable.

[0065] Other possible solutions also include: the sealing member 40 is rotatably arranged at the lower part of the mounting channel 51, and has only the freedom along the circumference of the rotation-stopping member 50, at this time, the circumferential locking groove 511 of the guide groove 510 is arranged at the upper edge of the mounting channel 51, and the axial movement groove 512 is arranged downwardly. The guide block 41 is arranged on the outer wall of the liquid outlet member 20 and arranged 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 downwardly and pressurizes the pump body 31.

[0066] In the above-mentioned embodiments, one of the liquid outlet member 20 and the sealing member 40 is rotatably arranged in the mounting channel 51, and the one has only the freedom along the circumference of the rotation-stopping member 50, that is, when one of the two rotates along the circumferential locking groove 511, the other of the two also rotates (that is, the two ends of the pump body 31 are fixedly connected with the liquid outlet member 20 and the sealing member 40, respectively). The different point of this embodiment is that one of the liquid outlet member 20 and the sealing member 40 is fixedly arranged in the mounting channel 51, and the other is arranged with the pump body 31, and the pump body 31 is rotatably connected with the one, so that when the other in this embodiment rotates along the circumferential locking groove 511, the one does not need to rotate.

[0067] In addition, the above-mentioned also relates to the problem of how to supplement the liquid after the liquid in the liquid storage member 10 is pumped out. Specifically, the sealing member 40 is first removed, at this time, the extrusion member 32 is manually pushed downwardly to move downwardly in the liquid storage member 10 until it returns to the initial state, then new liquid is supplemented into the liquid storage member 10, and then the sealing member 40 is sealed to the end of the liquid storage member 10.

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

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

[0070] Wherein, it can be known from the foregoing that the guide block 41 reciprocates in the circumferential locking groove 511 and the axial movement groove 512, and therefore it is important to determine the position of the guide block 41 in the circumferential locking groove 511 and the axial movement groove 512. It can be understood that the embodiment focuses on how the guide block 41 determines that it 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 rotation stopping strip 5111 is arranged at the middle position of the circumferential locking groove 511. In the initial state described above, the first rotation stopping strip 5111 is clamped in the rotation stopping groove 411, the sealing member 40 is rotated under the action of an external force to make the first rotation stopping strip 5111 and the rotation stopping groove 411 disengage, the guide block 41 moves to the axial movement groove 512, and then the rotation stopping groove 411 is clamped in the second rotation stopping strip 5121. At this time, it can be determined that the guide block 41 has completely entered the axial movement groove 512, and at this time the sealing member 40 moves axially under the action of the rotation stopping member 50. In this way, the arrangement of the first rotation stopping strip 5111 and the second rotation stopping strip 5121 can prompt the position state of the guide block 41, so as to determine whether the liquid storage device is in the locked state or the unlocked state. In addition, the first rotation stopping strip 5111 and the second rotation stopping strip 5121 can be arranged as separate schemes or as the same scheme.

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

[0073] Optionally, the liquid outlet member 20 comprises a rotating seat 21 and a liquid outlet nozzle 22. The liquid outlet channel is arranged in the rotating seat 21, and the liquid outlet nozzle 22 is arranged 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, a plurality of guide protrusions 211 are arranged on the outer wall of the rotating seat 21, and a plurality of guide grooves 412 are arranged in the sealing member 40. The rotating seat 21 is inserted into the sealing member 40, and the guide protrusions 211 are slidingly arranged in the guide grooves 412.

[0074] Wherein, the aforementioned liquid outlet 20 and the sealing member 40 have mutual approaching or moving away motion, and the two are only connected by the pump body 31. In this embodiment, the top of the sealing member 40 is provided with a plug-in slot, and a plurality of guide grooves 412 are arranged on the inner wall of the plug-in slot in the axial direction. The plurality of guide protrusions 211 on the outer wall of the rotating seat 21 and the plurality of guide grooves 412 in the plug-in slot of the rotation stop member 50 are matched one by one, and the guide protrusions 211 and the guide grooves 412 slide with each other, which provides guidance for the movement of the sealing member 40 to the liquid outlet 20 and improves the stability of the movement of the sealing member 40. In addition, the liquid outlet nozzle 22 of the present embodiment is arranged on the side wall of the rotating seat 21, so as to leave the end face of the rotating seat 21 away from the liquid storage member 10. When the liquid storage member 10 needs to move to the liquid outlet 20 to extrude the liquid, the above-mentioned end face of the rotating seat 21 can be used as a support surface, and the hand is abutted on the support surface to ensure the extrusion of the liquid storage member 10 to the pump body 31. In addition, in addition to the above-mentioned guiding effect in the axial direction, when the sealing member 40 is rotated, the guide protrusions 211 and the guide grooves 412 can also interact in the circumferential direction, so as to drive the rotation of the rotating seat 21.

[0075] Optionally, refer to 5- Figure 8 Further comprising a limiting shell 60, a containing groove 61 is arranged on the side wall of the limiting shell 60 in the circumferential direction, and one end of the limiting shell 60 is connected to the rotation stop member 50; the rotating seat 21 is sleeved and rotatably arranged in the limiting shell 60, and one end of the liquid outlet nozzle 22 penetrates through the containing groove 61 and is detachably connected to the rotating seat 21.

[0076] Wherein, in combination with the above-mentioned embodiment of the liquid outlet 20 moving relative to the rotation stop member 50 in the circumferential direction, another way of rotating connection between the liquid outlet 20 and the rotation stop member 50 is provided in this embodiment. Specifically, a limiting groove is arranged in the middle of the limiting shell 60, the rotating seat 21 is sleeved in the limiting groove, and the containing groove 61 is arranged through the side wall of the limiting groove. The rotating seat 21 is sleeved in the limiting groove, and the liquid outlet nozzle 22 is connected to the rotating seat 21 after penetrating through the containing groove 61, which gives the rotating seat 21 axial direction limiting. When the liquid storage member 10 moves to the rotating seat 21 for extrusion, the rotating seat 21 will not move in the axial direction, which ensures the completion of the extrusion action, and it is only necessary to hold the limiting shell 60 at this time. Of course, the containing groove 61 can give the liquid outlet nozzle 22 a space for movement in the circumferential direction, so the rotating seat 21 can also meet the above-mentioned function of synchronous rotation with the sealing member 40.

[0077] Preferably, the liquid outlet nozzle 22 and the rotating seat 21 are installed in a plug-in manner, and the key point is that a sealing ring is sleeved on the liquid outlet nozzle 22 to prevent liquid leakage.

[0078] Preferably, the limiting shell 60 is connected to the rotation-stopping piece 50 in a way that the inner wall of the limiting slot is clamped to the outer wall of the rotation-stopping piece 50. Specifically, the clamping way can be the clamping way of protrusions and recesses, which has the characteristics of simple structure and convenient assembly.

[0079] In addition, the outer contour of the limiting shell 60 is oval, the wall thickness of the limiting shell 60 decreases from the short semi-axis to the long semi-axis, and the short semi-axis of the limiting shell 60 is provided with a containing groove 61.

[0080] Further, the above-mentioned liquid outlet nozzle 22 is used to prevent the rotating seat 21 from moving in the axial direction, and the contact surface of the liquid outlet nozzle 22 with the containing groove 61 is limited, so as to better limit the movement of the rotating seat 21 in the axial direction when the liquid storage piece 10 is pressed upward, a protrusion is arranged on the inner wall of the limiting slot, which can be a protrusion or a protruding ring 62. Taking the protruding ring 62 as an example, a butt portion is arranged on the middle part of the outer wall of the rotating seat 21, and preferably, a plurality of butt edges 213 are arranged at intervals on the butt portion. When the rotating seat 21 is installed into the limiting slot, the upper part of the rotating seat 21 passes through the protruding ring 62, and the liquid outlet nozzle 22 is inserted into the upper part of the rotating seat 21. At this time, the butt edges 213 abut against the bottom surface of the protruding ring 62, so that the butt edges 213 and the liquid outlet nozzle 22 are arranged on the upper and lower sides of the protruding ring 62, which better limits the movement of the rotating seat 21 in the axial direction.

[0081] Optionally, one end of the containing groove 61 is provided with a hidden compartment 611. When the liquid storage device is in the locked state, the liquid outlet nozzle 22 is hidden in the hidden compartment 611 to hide it away from one end of the rotating seat 21.

[0082] The liquid storage device has a locked state and an unlocked state. Here, it is supplemented that when the liquid storage device switches back and forth between the locked state and the unlocked state, the liquid outlet nozzle 22 rotates from one end of the containing groove 61 to the other end. When the liquid storage device is in the locked state, the corresponding end of the containing groove 61 where the liquid outlet nozzle 22 is located is the closed position. When the liquid storage device is in the unlocked state, the corresponding end of the containing groove 61 where the liquid outlet nozzle 22 is located is the open position. The embodiment emphasizes that when the liquid outlet nozzle 22 is in the closed position, the end of the liquid outlet nozzle 22 away from the rotating seat 21 is hidden in the hidden compartment 611 (the limiting shell 60 has more accommodation space in the long semi-axis direction, so the liquid outlet nozzle 22 is exposed in the short semi-axis and hidden when turned to the long semi-axis). Specifically, the position corresponding to the closed position of the containing groove 61 is provided with an outward protruding shielding wall, and the outer end of the liquid outlet nozzle 22 located in the closed position is shielded 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 nozzle 22, avoiding the entry of external dust and other pollutants into the liquid outlet nozzle 22.

[0083] Optionally, referring to Figures 10-13Further comprising a force applying member 70, the outer wall of the force applying member 70 is provided with at least one force receiving surface 71; the middle part of the limiting shell 60 is provided with an axial through cavity, the force applying member 70 is arranged at the end of the rotating seat 21 far from the sealing member 40, and the force receiving surface 71 is located outside the through cavity in the limiting shell 60.

[0084] The force applying member 70 is used to drive the rotation of the rotating seat 21, and the force applying member 70 is a cap used to seal the top of the cavity and connected with the rotating seat 21. As mentioned above, the driving of the liquid storage device between the locked state and the unlocked state is realized by rotating the sealing member 40. However, as can be seen from the above, the upper end of the sealing member 40 is located in the mounting channel of the rotation stopping member 50, and the lower end of the rotation stopping member 50 is connected with the liquid storage member 10, so that it is inconvenient to operate the rotation of the sealing member 40. The embodiment is provided with the force applying member 70, which is connected with the upper end of the rotating seat 21 and extends outward at the top end. When it is necessary to convert between the locked state and the unlocked state, the force applying member 70 is more convenient and fast to operate. Further, in order to better rotate the force applying member 70, at least one force receiving surface 71 is arranged at the edge of the top of the force applying member 70, and the number thereof can be set according to the need. The force receiving surface 71 can be a flat surface or a concave surface, and the purpose is to enhance the convenience of hand gripping and increase the friction force of rotation. Preferably, the embodiment is provided with two force receiving surfaces 71 which are symmetrically arranged at the center of the force applying member 70.

[0085] In addition, the connection mode of the force applying member 70 and the rotating seat 21 can be selected as follows: the upper side of the rotating seat 21 is provided with an outer circular table 214, and the abutting edge 213 is arranged on the side wall of the outer circular table 214. Importantly, in the axial direction of the rotation stopping member 50, the outer circular table 214 is provided with at least two connection through holes 2141 which are symmetrically arranged about the center of the outer circular table 214. The lower part of the force applying member 70 is provided with at least two buckling blocks 72, which comprise an extension block 721 and a buckling protrusion 722. One end of the extension block 721 is arranged at the edge of the force applying member 70, and the other end extends along the axial direction of the force applying member 70. The inner side of the other end of the extension block 721 is provided with the buckling protrusion 722. It should be noted that the extension block 721 has a certain elasticity. When the force applying member 70 is installed on the rotating seat 21 from top to bottom, the inner side of the buckling protrusion 722 abuts against the inner side of the connection through hole 2141 at this time, the extension block 721 is deformed by being pushed outward, and the force applying member 70 is pushed downward all the time. After the buckling protrusion 722 passes through the connection through hole 2141, the extension block 721 restores, and the buckling protrusion 722 buckles the bottom of the connection through hole 2141. In addition, in order to facilitate the buckling protrusion 722 to be pushed into the connection through hole 2141, the lower end of the inner side of the buckling protrusion 722 is provided with an inclined surface which inclines from bottom to top and from outside to inside. The inclined surface is used to abut against the inner side of the connection through hole 2141, and the abutment of the inclined surface is not prone to the problems of jamming or abutting to a dead end.

[0086] Further, the lower edge of the force applying member 70 is also provided with a buckling notch 73, when the force applying member 70 is buckled and mounted to the top of the rotating seat 21, at this time, the buckling notch 73 is buckled on the liquid outlet nozzle 22 from top to bottom, so that when the force applying member 70 is rotated, the force applying member 70 can better drive the liquid outlet nozzle 22 to move together.

[0087] Optionally, a holding member 80 is further included, the holding member 80 is covered outside the liquid storage member 10, and one end of the holding member 80 is connected to the rotation stopping member 50, an external force is applied to the holding member 80, the holding member 80 is pressed and acts on the liquid storage member 10, so that the liquid storage member 10 moves in the axial direction of the rotation stopping member 50.

[0088] Among them, the middle part of the holding member 80 is a through structure, the connection between the holding member 80 and the rotation stopping member 50 can refer to the connection mode between the limiting shell 60 and the rotation stopping member 50, which will not be repeated here. In particular, in order to make the limiting shell 60 and the holding member 80 have axial positioning on the rotation stopping member 50, the middle part of the outer wall of the rotation stopping member 50 is preferably provided with a positioning convex ring 52, and the lower end of the limiting shell 60 and the upper end of the holding member 80 are respectively abutted on the top surface and the bottom surface of the positioning convex ring 52.

[0089] The focus of the embodiment is that the holding member 80 has elasticity, when the liquid storage device is in the unlocked state, the holding member 80 is squeezed inward under force, the holding member 80 acts on the liquid storage member 10, and the liquid storage member 10 moves close to the liquid outlet member 20 (i.e. upward movement) to press the liquid outlet. When the holding member 80 is released, the holding member 80 elastically recovers, the liquid storage member 10 moves away from the liquid outlet member 20 (i.e. downward movement), and when the liquid storage member 10 drops to the lowest position, the liquid storage device can be turned into the locked state at this time.

[0090] Optionally, the inner wall of the holding member 80 is provided with a pressing portion 82, when an external force is applied to the holding member 80, the pressing portion 82 of the holding member 80 acts on one end of the liquid storage member 10 away from the rotation stopping member 50; and / or, the holding member 80 is provided with at least one hollow groove 81; the hollow groove 81 is provided extending from one end of the holding member 80 away from the rotation stopping member 50 to the rotation stopping member 50.

[0091] Among them, the two schemes of the pressing portion 82 and the hollow groove 81 of the embodiment can be implemented separately or set at the same time.

[0092] Among them, the pressing portion 82 is a pressing block provided on the hollow inner wall of the holding member 80, when the holding member 80 is squeezed inward, the pressing block is used to abut and push the liquid storage member 10 to move upward.

[0093] In addition, the inner side of the pressing protrusion is provided with a pressing surface matched with the bottom of the liquid storage piece 10. The pressing surface is matched with the bottom of the liquid storage piece 10, and the contact surface of the two is increased, which is more beneficial to the stable pushing of the pressing protrusion to the liquid storage piece 10. For example, the liquid storage piece 10 in the foregoing is a round bottom, and the pressing surface of the embodiment can be provided with a matched arc shape. Alternatively, the pressing surface is a slope of the pressing protrusion, which is inclined from bottom to top and from inside to outside. That is, the pressing protrusion has a structure of being small at the top and large at the bottom. The actual consideration of the structure is that when the holding piece 80 is pressed, the deformation of the lower end is larger, and the lower part of the pressing protrusion can better support and extrude the bottom of the liquid storage piece 10.

[0094] In addition, the holding piece 80 mentioned above will press and extrude the liquid storage piece 10. In the embodiment, in order to give the holding piece more deformation, the holding piece 80 is provided with a hollow groove 81. Therefore, the hollow groove 81 provides more deformation space for the holding piece 80, which is beneficial to the extrusion of the holding piece 80 inward and ensures that the liquid storage piece 10 has enough extrusion stroke in the axial direction.

[0095] In the embodiment, the hollow groove 81 is a strip-shaped groove. Preferably, the hollow groove 81 can be provided with a structure of being small at the top and large at the bottom. The meaning of the structure is that when the holding piece 80 is actually pressed, the bottom end of the holding piece 80 can be pressed. The upper part of the hollow groove 81 is smaller, so that the upper part has greater rigidity and can be used as a force point, which is more convenient for the pressing operation of the lower end of the holding piece 80. In addition, the number of the hollow groove 81 can be one, but preferably two hollow grooves 81 are symmetric about the center of the holding piece 80. The two hollow grooves 81 can better balance and absorb the deformation of the two sides of the holding piece 80.

[0096] In addition, in combination with the above, the outer contour of the holding piece 80 can be said to be elliptical in reference to the limiting shell 60, so that the two form a unity and improve the appearance. In addition, the hollow groove 81 can be provided on the side wall close to the short side, that is, the width of the hollow groove 81 is provided along the long side direction. In this way, the setting space of the width of the hollow groove 81 is larger, and the hollow groove 81 with larger width can provide more extrusion space to the middle part, which is more beneficial to the extrusion of the liquid storage piece 10 by the pressing part 82.

[0097] Optionally, the liquid storage piece 10 is a deformable piece. When the holding piece 80 acts on the liquid storage piece 10, the liquid storage piece 10 is deformed and extrudes the liquid in the liquid storage piece 10 to move to the liquid outlet piece 20.

[0098] Wherein, the aforementioned extrusion piece 32 can move in the axial direction of the liquid storage piece 10, and different from the embodiment, the liquid storage piece 10 has a deformable function, when the holding piece 80 extrudes the liquid storage piece 10 inward, the liquid storage piece 10 moves upward while its bottom is also deformed under pressure, the bottom deformation compresses the extrusion piece 32 in the bottom of the liquid storage piece 10, the extrusion piece 32 moves upward in the interior of the liquid storage piece 10, thereby further pushing the liquid in the liquid storage piece 10 to flow out, improving the liquid outflow efficiency. Of course, after the extrusion on the holding piece 80 is released, the liquid storage piece 10 not only moves downward, but also rebounds and expands by itself.

[0099] In summary, the complete statement of the overall working principle of the liquid storage device is as follows:

[0100] In the initial state, the liquid storage device is in the locked state, and the liquid outlet nozzle 22 is located in the hidden warehouse 611. At this time, the liquid storage device is converted to the unlocked state by rotating the force applying piece 70 to apply force, at this time, the liquid outlet nozzle 22 is turned out from the hidden warehouse 611 to the open position, and the locking and unlocking operations are described above, which will not be repeated here. Hold the lower end of the holding piece 80 and press inward, the pressure applying part 82 acts on the bottom of the liquid storage piece 10, the liquid storage piece 10 moves in the axial direction, the pump body 31 is pressed to deliver the liquid in the liquid storage piece 10 to the liquid outlet piece 20, and the liquid is finally discharged from the liquid outlet nozzle 22. In addition, if the liquid storage piece 10 is deformable, the extrusion deformation of the liquid storage piece 10 and the upward movement of the extrusion piece 32 are also accompanied, please refer to the foregoing.

[0101] Then if the pressure on the lower end of the holding piece 80 is released, at this time the pump body 31 restores and pushes the liquid storage piece 10 to return downward to the lowest position, at this time it may also be accompanied by the expansion recovery of the liquid storage piece 10; finally, the open position of the liquid outlet nozzle 22 is turned into the hidden warehouse 611 by the force applying piece 70, at the same time, the liquid storage device is also converted from the unlocked state to the locked state.

[0102] The technical means disclosed by the utility model scheme is not limited to the technical means disclosed by the above-mentioned embodiment, and also includes the technical scheme composed of any combination of the above technical features. It should be noted that for ordinary skilled persons in the art, without departing from the principle of the utility model, some improvements and decorations can be made, which are also considered as the protection range of the utility model.
