Description

Technical Field

[0001] The utility model relates to the technical field of perfume utensils, in particular to a liquid dispensing bottle. Background Art

[0002] Perfume, a liquid mixture of essential oils, fixatives, alcohol, and ethyl acetate, emits a pleasant aroma and is an important cosmetic product. Perfume is often packaged in primary bottles. Many primary bottles are large and difficult to carry for daily use, requiring the perfume to be dispensed into smaller bottles. However, this process can easily spill, requiring scrubbing and cleaning. To address this issue, a secondary bottle with a bottom-mounted liquid filling structure has emerged. This bottom-mounted filling structure connects to the primary bottle's liquid outlet pipe to allow liquid to be added to the secondary bottle.

[0003] However, the appearance of different styles of perfume mother bottles on the market may vary, so the shapes of their liquid outlet tubes (such as flat mouth, trumpet mouth, etc.) and the size of the mouth are different. In addition, the liquid outlet tube of a conventional perfume mother bottle usually protrudes from its bottle mouth. However, in order to better adapt to the appearance design of the perfume mother bottle, the liquid outlet tube of some mother bottles is recessed in the bottle mouth to make the bottle body shorter and more delicate and compact, resulting in the conventional sub-bottle being unable to directly connect with the liquid outlet tube due to collision with the bottle mouth. The sub-bottles in the prior art cannot adapt to different liquid outlet tube designs at the same time. Therefore, during the filling process, the inability to adapt can easily cause liquid leakage or failure to fill, resulting in the user needing to configure multiple corresponding matching sub-bottles, which not only increases the user's usage cost, but also generates a large amount of resource waste. Utility Model Content

[0004] Based on this, it is necessary to provide a liquid sub-filling bottle to address the problem that the sub-filling bottle in the prior art cannot be adapted to different mother bottle liquid outlet tube designs at the same time, which easily causes liquid leakage or inability to be filled.

[0005] A liquid dispensing bottle comprises: a shell assembly, the shell assembly being provided with a liquid storage cavity; a first liquid-filling unit, the first liquid-filling unit comprising a first liquid-filling column, the first liquid-filling column being movably arranged in the shell assembly, the liquid inlet end of the first liquid-filling column extending out of the shell assembly; a second liquid-filling unit, the second liquid-filling unit being detachably arranged on the outside of the shell assembly, the second liquid-filling unit comprising a second liquid-filling column, the liquid outlet end of the second liquid-filling column being adapted to be inserted into the liquid inlet end of the first liquid-filling column, the liquid inlet end of the second liquid-filling column forming an abutment surface; the first liquid-filling column being configured to be directly or indirectly connected to the liquid outlet pipe of the mother bottle through the abutment surface to fill the liquid storage cavity with liquid.

[0006] The present application provides a liquid filling bottle, which includes a first liquid filling unit and a second liquid filling unit. The second liquid filling unit can be disassembled or installed on the outside of the shell assembly according to user needs. When the second liquid filling unit is connected to the shell assembly, the abutting surface of the second liquid filling column can be sealed and abutted with the common cylindrical flat-mouthed liquid outlet tube protruding from the mouth of the mother bottle, so that the mother bottle can be connected to the first liquid filling column through the second liquid filling column to perform liquid filling operations; when the second liquid filling unit is disassembled and separated from the shell assembly, the liquid inlet end of the first liquid filling column can be directly connected to the liquid outlet tube of the mother bottle. The liquid inlet end of the first liquid filling column is located outside the shell assembly and can be inserted into the liquid outlet tube embedded in the inside of the mouth of the mother bottle, thereby avoiding collision between the shell assembly and the mouth of the mother bottle to hinder liquid filling. Through the cooperation of the first liquid filling column and the second liquid filling column, this solution can be widely used with mother bottle liquid outlet tubes of different designs, which can provide convenience for users and reduce usage costs.

[0007] In one embodiment, the liquid inlet end of the first liquid-filling column is tapered. This tapered inlet end allows the first liquid-filling column to better fit the bell-shaped outlet tube of the mother bottle. This not only increases the connection area, ensuring a leak-proof seal between the first liquid-filling column and the mother bottle outlet tube, but also allows for compatibility with a wider range of bell-shaped outlet tubes of varying diameters.

[0008] In one embodiment, the diameter of the liquid inlet end of the second liquid filling column is smaller than the diameter of the liquid inlet end of the first liquid filling column. The diameter of the cylindrical flat-mouthed liquid outlet tube used in mother bottles on the market is generally smaller than the diameter of the bell-mouthed liquid outlet tube. This design can better adapt to the filling of most mother bottles currently on the market.

[0009] In one embodiment, the second liquid-filled column includes a column body and a sealing portion, the sealing portion is provided with a socket, one end of the column body is adapted to be inserted into the liquid inlet end of the first liquid-filled column, the other end of the column body is adapted to be inserted into the socket and exposed through the socket, and the column body and / or the sealing portion are formed with the abutment surface. By adopting the above structure, when the second liquid-filled unit is connected to the shell assembly, one end of the column body is connected to the liquid inlet end of the first liquid-filled column to communicate with the first liquid-filled column, and at the same time, the abutment surface formed by the sealing portion located on the outer peripheral side of the column can better adapt to more liquid outlet pipes of different calibers, and the tight abutment between the abutment surface and the liquid outlet pipe can ensure that the connection between the second liquid-filled column and the liquid outlet pipe is not easy to leak.

[0010] In one embodiment, the column and the sealing portion are integrally formed.

[0011] In one embodiment, the shell assembly is provided with a first mounting cavity and a first through hole connecting the first mounting cavity and the liquid storage cavity, the first liquid-filled column is movably arranged in the first mounting cavity, the first liquid-filled column is provided with a liquid filling channel, the side wall of the first liquid-filled column close to the liquid storage cavity is provided with a liquid outlet connected to the liquid filling channel, the first liquid-filled column can be telescopically movable relative to the first through hole and has at least a first position and a second position, when the first liquid-filled column is in the first position, the liquid outlet is blocked from the liquid storage cavity, when the first liquid-filled column is in the second position, the liquid outlet is connected to the liquid filling channel and the liquid storage cavity, and the second liquid-filled column is configured to be able to rise along the length direction of the first liquid-filled column under the action of external force and push the first liquid-filled column to move from the first position to the second position. By adopting the above structure, when filling liquid, the user connects the liquid inlet end of the first liquid filling column or the liquid inlet end of the second liquid filling column downward to the liquid outlet pipe of the mother bottle and presses the liquid sub-filling bottle downward as a whole. The liquid outlet pipe of the mother bottle will push the first liquid filling column and / or the second liquid filling column to rise, so that the first liquid filling column moves from the first position to the second position and communicates with the liquid storage cavity. At this time, the liquid is output from the liquid outlet pipe of the mother bottle and enters the liquid storage cavity through the liquid outlet. When the liquid filling is completed, the first liquid filling column can be reset to the first position so that the liquid outlet is connected to the liquid storage cavity and blocked, preventing the liquid in the liquid storage cavity from flowing back through the first liquid filling column. The above liquid filling structure is simple and easy to operate. The liquid filling work can be easily completed by repeatedly pressing the liquid sub-filling bottle back and forth on the liquid outlet pipe of the mother bottle.

[0012] In one embodiment, the second liquid-filling unit further comprises a connecting seat, wherein the connecting seat and the shell assembly are detachably connected, the connecting seat is provided with a second mounting cavity, and opposite sides of the connecting seat are respectively provided with a first opening and a second opening capable of communicating with the second mounting cavity, the second liquid-filling column is movably arranged in the second mounting cavity, the liquid inlet end of the second liquid-filling column is exposed to the outside through the first opening, and the liquid outlet end of the second liquid-filling column extends out of the second mounting cavity through the second opening and is adapted to be plugged into the liquid inlet end of the first liquid-filling column. By adopting the above structure, the connecting seat is provided with a second mounting cavity for limiting the assembly of the second liquid-filling column, so that the second liquid-filling column can be hidden in the second mounting cavity, thereby forming a protective effect and avoiding the risk of collision and breakage. At the same time, the connecting seat can be used to realize the detachable connection between the second liquid-filling unit and the shell assembly. When the connecting seat is aligned and connected with the shell assembly, the liquid outlet end of the second liquid-filling column can be plugged into the liquid inlet end of the first liquid-filling column. When the connecting seat is separated from the shell assembly, the second liquid-filling column and the first liquid-filling column are separated at the same time.

[0013] In one embodiment, the second liquid filling unit further includes a second elastic member, the two ends of which are respectively against the inner wall of the second mounting cavity and the second liquid filling column. When the second liquid filling column rises under the action of an external force, the second elastic member undergoes elastic deformation to provide an elastic restoring force for the second liquid filling column to reset. By adopting the above structure, when the liquid filling is completed and the liquid outlet tube of the mother bottle leaves and the supporting force on the second liquid filling column disappears, at this time, under the action of the elastic restoring force provided by the second elastic member, the second liquid filling column can quickly reset and fall back to facilitate subsequent use. Moreover, when the user disassembles the connecting seat from the shell assembly, the second elastic member can cooperate with the connecting seat to limit the second liquid filling column, so that the liquid outlet end of the second liquid filling column can automatically separate from the first liquid filling column.

[0014] In one embodiment, the connecting base includes a connecting portion and a positioning portion, the connecting portion and the housing assembly are detachably connected, the positioning portion is detachably provided on the connecting portion and encloses the connecting portion to form the second mounting cavity, and the end of the second elastic member away from the second liquid-filled column abuts against the connecting portion or the positioning portion. The provision of a detachable combination of the connecting portion and the positioning portion to enclose the second mounting cavity facilitates assembly of the second liquid-filled column and the second elastic member.

[0015] In one embodiment, a first accommodating groove and the first opening are provided on a side of the connecting portion close to the first mounting cavity, the first accommodating groove is communicated with the first opening, the positioning portion is located in the first accommodating groove, the positioning portion is provided with a second accommodating groove, the inner wall of the second accommodating groove and the bottom wall of the first accommodating groove are combined to form the second mounting cavity, the bottom wall of the second accommodating groove is provided with the second opening, and the end of the second elastic member away from the second liquid-filled column is against the positioning portion.

[0016] In one embodiment, the bottom wall of the first receiving groove is recessed to form a limiting hole, which is connected to the first opening, and the positioning portion is inserted into the limiting hole. The provision of the limiting hole can form a limiting effect on the positioning portion, facilitating rapid positioning and assembly of the positioning portion.

[0017] In one embodiment, a first accommodating groove is provided on the side of the connecting portion away from the first mounting cavity, the bottom wall of the first accommodating groove is provided with the second opening, the positioning portion is arranged in the first accommodating groove, the positioning portion is provided with a second accommodating groove, the inner wall of the second accommodating groove and the bottom wall of the first accommodating groove are combined to form the second mounting cavity, the bottom wall of the second accommodating groove is provided with the first opening, and the end of the second elastic member away from the second liquid-filled column is against the connecting portion.

[0018] In one embodiment, the connector is connected to the housing assembly via at least one of a threaded connection, a snap-fit ​​connection, and a magnetic connection. This connection method not only provides a stable fixation effect, but also allows for quick assembly and separation of the connector and housing assembly, making operation simple and user-friendly.

[0019] In one embodiment, an annular groove is formed on the outer peripheral wall of the second liquid-filling column on a side facing away from the first liquid-filling column, and a protrusion on the inner wall of the first opening forms a positioning step, which is adapted to fit within the annular groove. By forming the positioning step and the annular groove at the first opening of the connector and on the second liquid-filling column, respectively, the positioning step and the annular groove cooperate to provide positioning support for the second liquid-filling column, ensuring that the second liquid-filling column and the second elastic member are stably positioned within the second mounting cavity and prevent them from falling out of the bottle.

[0020] In one embodiment, a first sealing ring is further included, wherein the first sealing ring is disposed at the first through hole, and the first liquid-filled column is movably inserted into the first sealing ring, and the first sealing ring is used to seal the connection between the first liquid-filled column and the first through hole. The provision of the first sealing ring can improve the sealing performance of the connection between the first liquid-filled column and the first through hole. When the first liquid-filled column is in the first position, the first liquid-filled column and the first sealing ring cooperate to seal the first through hole, ensuring that the liquid storage chamber does not leak. Furthermore, the tight connection between the first sealing ring and the first liquid-filled column can better cooperate with the telescopic movement of the first liquid-filled column, effectively preventing the liquid in the liquid storage chamber from leaking through the connection when the first liquid-filled column moves.

[0021] In one embodiment, the first liquid filling unit further includes a first elastic member, the two ends of which are respectively against the inner wall of the first mounting cavity and the first liquid filling column. When the first liquid filling column moves from the first position to the second position under the action of an external force, the first elastic member undergoes elastic deformation to provide an elastic restoring force for the liquid filling column to return to the first position. By setting the first elastic member, when the filling is completed, the thrust of the liquid outlet pipe of the mother bottle disappears. At this time, under the action of the elastic restoring force provided by the first elastic member, the first liquid filling column quickly moves downward to block the connection between the liquid outlet and the liquid storage cavity, thereby preventing leakage. In addition, when the first liquid filling column is accidentally collided, the first elastic member can also provide a certain resistance to prevent the first liquid filling column from rising and leaking.

[0022] In one embodiment, the outer peripheral wall of the first liquid-filled column on a side away from the liquid storage cavity is raised to form a base, and the first liquid-filled unit further includes an elastic pad, which is disposed on the first liquid-filled column or the housing assembly and is located between the base and the bottom wall of the first mounting cavity. Due to the provision of the elastic pad, when the first liquid-filled column is moved from the second position to the first position under the action of the first elastic member to reset, the elastic pad located between the base and the bottom wall of the first mounting cavity can act as an elastic buffer, thereby preventing the first liquid-filled column from directly colliding with the bottom wall of the first mounting cavity and causing wear and tear.

[0023] In one embodiment, the elastic pad is sleeved on the outside of the first liquid-filled column, thereby facilitating the positioning of the elastic pad and improving assembly efficiency.

[0024] In one embodiment, the shell assembly is provided with a second through hole connecting the liquid storage chamber and the first installation chamber, and also includes an exhaust assembly, the exhaust assembly includes an exhaust pipe and an air guide column, the exhaust pipe is arranged in the liquid storage chamber, the bottom end of the exhaust pipe is inserted in the second through hole, the air guide column is located in the first installation chamber, the air guide column is arranged on the first liquid-filled column, the air guide column is provided with an air guide channel, and the air guide column is configured to be able to extend and retract relative to the second through hole under the drive of the first liquid-filled column, so that the air guide channel is connected or blocked to connect or interrupt the exhaust pipe with the outside world. By adopting the above structure, the movement of the air guide column is driven by the first liquid filling column to realize the control of liquid injection and exhaust opening and closing respectively and simultaneously. The exhaust pipe is located in the liquid storage chamber and is inserted on the second through hole. The air guide column is arranged on the first liquid filling column. Therefore, when filling, the first liquid filling column moves from the first position to the second position, which will synchronously drive the air guide column to move relative to the second through hole, so that the air guide column can connect the exhaust pipe with the outside world, thereby allowing the gas inside the liquid storage chamber to be discharged synchronously when filling. An independent air guide channel for connecting the exhaust pipe with the outside world is provided on the air guide column, which can further ensure smooth exhaust and improve the exhaust efficiency.

[0025] In one embodiment, when the first liquid-filling column is in the first position, the air-guiding column blocks the second through-hole and the air-guiding channel is blocked from the exhaust pipe. When the air-guiding column is in the second position, the air-guiding column extends into the second through-hole, and the air-guiding channel connects the exhaust pipe with the outside world. Specifically, the air inlet of the air-guiding channel is located on the side wall of the air-guiding column near the second through-hole. Driven by the first liquid-filling column, the air-guiding column rises and extends into the second through-hole, so that the air inlet of the air-guiding channel is connected to the exhaust pipe, so that the gas inside the liquid storage chamber can be discharged synchronously during filling. When the filling is completed, the first liquid-filling column returns to the second position and drives the air-guiding column to reset so that the air-guiding column can block the second through-hole, thereby ensuring that the liquid in the liquid storage chamber does not leak. By adopting the above structure, when the air-guiding column is driven by the liquid-filling component to extend and retract relative to the second through-hole, the sliding cooperation between the air-guiding column and the shell component or the sealing element forms a dynamic seal on the air inlet end of the air-guiding channel, thereby realizing the control of the opening and closing of the exhaust.

[0026] In one embodiment, a second sealing ring is further included, wherein the second sealing ring is disposed at the second through hole, and the air guide column is movably inserted into the second sealing ring, and the second sealing ring is used to seal the connection between the air guide column and the second through hole. The provision of the second sealing ring can improve the sealing performance of the connection between the air guide column and the second through hole. When the first liquid-filled column is in the first position, the air guide column can cooperate with the second sealing ring to seal the second through hole, ensuring that the liquid storage chamber does not leak. Furthermore, the tight connection between the second sealing ring and the air guide column can better cooperate with the telescopic movement of the air guide column, effectively preventing the liquid in the liquid storage chamber from leaking through the connection when the air guide column moves.

[0027] In one embodiment, the second sealing ring is integrally formed with the first sealing ring, so that the second sealing ring and the first sealing ring are detachably mounted on the base, thereby improving installation efficiency.

[0028] In one embodiment, when the first liquid-filled column is in the first position, the outlet end of the air guide channel is sealed and connected to the bottom wall of the first mounting cavity, so that the air guide channel is blocked; when the first liquid-filled column is in the second position, the outlet end is away from the bottom wall of the first mounting cavity, and a first exhaust gap is formed between the outlet end and the bottom wall of the mounting cavity, and the outlet end is connected to the outside world through the first exhaust gap. By adopting the above structure, when not filled with liquid, the outlet end of the air guide channel is sealed and connected to the bottom wall of the first mounting cavity, so that the outlet end is blocked, preventing the liquid in the liquid storage cavity from entering the exhaust pipe and leaking through the air guide column; when filled with liquid, the air guide column moves toward the second through hole under the drive of the first liquid-filled column, so that the outlet end of the air guide channel is away from the bottom wall of the first mounting cavity, so that the outlet end is opened, and a first exhaust gap is formed between the outlet end and the inner wall of the mounting cavity to connect the outlet end with the outside world, so that the gas in the liquid storage cavity can be discharged through the exhaust pipe and the air guide column in sequence, ensuring smooth filling.

[0029] In one embodiment, when the first liquid-filled column is in the first position, the second liquid-filled column is sealed and connected to the bottom wall of the second mounting cavity, so that the second mounting cavity is separated from the first opening; when the first liquid-filled column is in the second position, the second liquid-filled column is away from the bottom wall of the first mounting cavity, and a second exhaust gap is formed between the second liquid-filled column and the inner wall of the mounting cavity, and the first exhaust gap is connected to the first opening through the second exhaust gap.

[0050] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0051] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0052] The liquid dispensing bottles according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0053] like Figures 1 to 5 As shown, this embodiment discloses a liquid filling bottle, comprising: a shell assembly 1, the shell assembly 1 is provided with a liquid storage chamber 101; a first liquid filling unit 2, the first liquid filling unit 2 includes a first liquid filling column 21, the first liquid filling column 21 is movably arranged in the shell assembly 1, and the liquid inlet end of the first liquid filling column 21 extends out of the shell assembly 1; a second liquid filling unit 3, the second liquid filling unit 3 is detachably arranged on the outside of the shell assembly 1, the second liquid filling unit 3 includes a second liquid filling column 31, the liquid outlet end of the second liquid filling column 31 is adapted to be inserted into the liquid inlet end of the first liquid filling column 21, and the liquid inlet end of the second liquid filling column 31 forms an abutment surface 3121; the first liquid filling column 21 is configured to be directly or indirectly connected to the liquid outlet pipe of the mother bottle through the abutment surface 3121 to fill the liquid storage chamber 101 with liquid.

[0054] The present application provides a liquid filling bottle, which includes a first liquid filling unit 2 and a second liquid filling unit 3. The second liquid filling unit 3 can be removed or installed on the outside of the shell component 1 according to user needs. When the second liquid filling unit 3 is connected to the shell component 1, the abutting surface 3121 of the second liquid filling column 31 can be sealed and abutted with the common cylindrical flat-mouthed liquid outlet pipe 210 protruding from the bottle mouth 220 of the mother bottle 200, so that the mother bottle 200 can be connected with the first liquid filling column 21 through the second liquid filling column 31 to perform liquid filling operation; when the second liquid filling unit 3 is disassembled and separated from the shell component 1, the liquid inlet end of the first liquid filling column 21 can be directly connected to the liquid outlet pipe 210 of the mother bottle 200. The liquid inlet end of the first liquid filling column 21 is located outside the shell component 1 and can be inserted into the liquid outlet pipe 210 embedded in the bottle mouth 220 of the mother bottle 200, thereby avoiding collision between the shell component 1 and the bottle mouth 220 of the mother bottle 200 to hinder liquid filling. Through the cooperation of the first liquid-filling column 21 and the second liquid-filling column 31 , this solution can be widely used with the liquid outlet tube 210 of the mother bottle 200 of different designs, which can provide convenience for users and reduce usage costs.

[0055] like Figure 1 and Figure 4 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further provides that the liquid inlet end of the first liquid filling column 21 is tapered. The tapered liquid inlet end allows the first liquid filling column 21 to better adapt to the bell-shaped liquid outlet tube 210 of the mother bottle 200. This not only increases the connection area, ensuring a sealed connection between the first liquid filling column 21 and the mother bottle 200 liquid outlet tube 210 to prevent leakage, but also allows for adaption to a wider range of bell-shaped liquid outlet tubes 210 with different diameters.

[0056] like Figure 3 As shown, in addition to the features of the above embodiment, this embodiment further provides that the diameter of the liquid inlet end of the second liquid filling column 31 is smaller than the diameter of the liquid inlet end of the first liquid filling column 21. The diameter of the cylindrical flat-mouthed liquid outlet tube 210 used in mother bottles 200 on the market is generally smaller than the diameter of the bell-mouthed liquid outlet tube 210. This design can better adapt to the filling of most mother bottles 200 currently on the market.

[0057] like Figure 3 and Figure 7As shown, in addition to the features of the above embodiment, this embodiment further defines that: the second liquid filling column 31 includes a column body 311 and a sealing portion 312, the sealing portion 312 is provided with an insertion hole 309, one end of the column body 311 is adapted to be inserted into the liquid inlet end of the first liquid filling column 21, and the other end of the column body 311 is adapted to be inserted into the insertion hole 309 and exposed through the insertion hole 309, and the column body 311 and / or the sealing portion 312 are formed with an abutment surface 3121. By adopting the above structure, when the second liquid filling unit 3 is connected to the housing assembly 1, one end of the column body 311 is connected to the liquid inlet end of the first liquid filling column 21 and communicates with the first liquid filling column 21. At the same time, the abutment surface 3121 formed by the sealing portion 312 on the outer circumference of the column body 311 can better adapt to a variety of liquid outlet pipes 210 with different calibers. The tight abutment between the abutment surface 3121 and the liquid outlet pipe 210 ensures that the connection between the second liquid filling column 31 and the liquid outlet pipe 210 is not easily leaked.

[0058] In addition to the features of the above embodiments, this embodiment further defines that: the column 311 and the sealing portion 312 are integrally formed.

By adopting the above structure, when filling liquid, the user connects the liquid inlet end of the first liquid filling column 21 or the liquid inlet end of the second liquid filling column 31 downward to the liquid outlet pipe 210 of the mother bottle 200 and presses the liquid sub-filling bottle downward as a whole. The liquid outlet pipe 210 of the mother bottle 200 will push the first liquid filling column 21 and / or the second liquid filling column 31 to rise, so that the first liquid filling column 21 moves from the first position to the second position and communicates with the liquid storage chamber 101. At this time, the liquid is output from the liquid outlet pipe 210 of the mother bottle 200 and enters the liquid storage chamber 101 through the liquid outlet 202. When the filling is completed, the first liquid filling column 21 can be reset to the first position so that the liquid outlet 202 is connected to the liquid storage chamber 101 and blocked, thereby preventing the liquid in the liquid storage chamber 101 from flowing back through the first liquid filling column 21.

By adopting the above structure, the connecting seat 32 is provided with a second installation cavity 301 for limiting the assembly of the second liquid-filling column 31, so that the second liquid-filling column 31 can be hidden in the second installation cavity 301, thereby forming a protective effect to avoid the risk of collision and breakage. At the same time, the connecting seat 32 can be used to realize the detachable connection between the second liquid-filling unit 3 and the shell assembly 1. When the connecting seat 32 is aligned and connected with the shell assembly 1, the liquid outlet end of the second liquid-filling column 31 can be plugged into the liquid inlet end of the first liquid-filling column 21. When the connecting seat 32 is separated from the shell assembly 1, the second liquid-filling column 31 and the first liquid-filling column 21 are separated at the same time.

[0061] like Figure 3 and Figure 7 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the second liquid filling unit 3 also includes a second elastic member 33, the two ends of the second elastic member 33 are respectively against the inner wall of the second installation cavity 301 and the second liquid filling column 31, and when the second liquid filling column 31 rises under the action of an external force, the second elastic member 33 undergoes elastic deformation to provide elastic recovery force for the second liquid filling column 31 to return to its original position. By adopting the above structure, when the liquid filling is completed and the liquid outlet pipe 210 of the mother bottle 200 leaves and the supporting force on the second liquid filling column 31 disappears, at this time, under the action of the elastic recovery force provided by the second elastic member 33, the second liquid filling column 31 can quickly return to its original position and fall back, so as to facilitate subsequent use. Moreover, when the user disassembles the connecting seat 32 from the shell assembly 1, the second elastic member 33 can cooperate with the connecting seat 32 to limit the second liquid filling column 31, so that the liquid outlet end of the second liquid filling column 31 can automatically separate from the first liquid filling column 21.

By adopting such a connection method, a stable fixing effect can be achieved while also enabling the connection base 32 to be quickly assembled or separated from the housing assembly 1, which is simple to operate and convenient for users.

[0067] like Figure 3 and Figure 7 As shown, in addition to the features of the above-described embodiment, this embodiment further defines: an annular groove 307 is provided on the outer peripheral wall of the second liquid-filling column 31 on a side away from the first liquid-filling column 21, and a positioning step 3211 is formed on the inner wall of the first opening 302. The positioning step 3211 and the annular groove 307 can be adapted for installation. By forming the positioning step 3211 and the annular groove 307 at the first opening 302 of the connecting seat 32 and on the second liquid-filling column 31, respectively, the two cooperate to provide a positioning and support function for the second liquid-filling column 31, so that the second liquid-filling column 31 and the second elastic member 33 can be stably installed in the second mounting cavity 301 and prevent them from falling out of the bottle.

[0068] like Figure 4 and Figure 6 As shown, in addition to the features of the above-mentioned embodiment, this embodiment is further defined as follows: it also includes a first sealing ring 5, the first sealing ring 5 is provided at the first through hole 103, the first liquid-filled column 21 is movably inserted in the first sealing ring 5, and the first sealing ring 5 is used to seal the connection between the first liquid-filled column 21 and the first through hole 103. The provision of the first sealing ring 5 can improve the sealing performance of the connection between the first liquid-filled column 21 and the first through hole 103. When the first liquid-filled column 21 is in the first position, the first liquid-filled column 21 cooperates with the first sealing ring 5 to seal the first through hole 103, ensuring that the liquid storage chamber 101 does not leak. Moreover, the tight connection between the first sealing ring 5 and the first liquid-filled column 21 can better cooperate with the telescopic movement of the first liquid-filled column 21, effectively preventing the liquid in the liquid storage chamber 101 from leaking through the connection when the first liquid-filled column 21 moves.

[0069] like Figure 3 and Figure 6As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the first liquid filling unit 2 also includes a first elastic member 22, the two ends of the first elastic member 22 respectively abut against the inner wall of the first mounting cavity 102 and the first liquid filling column 21. When the first liquid filling column 21 moves from the first position to the second position under the action of an external force, the first elastic member 22 elastically deforms to provide an elastic restoring force for the liquid filling column to return to the first position. Through the provision of the first elastic member 22, when the filling is completed, the thrust of the liquid outlet pipe 210 of the mother bottle 200 disappears. At this time, under the action of the elastic restoring force provided by the first elastic member 22, the first liquid filling column 21 quickly moves downward, so that the liquid outlet 202 is connected to the liquid storage cavity 101 and is blocked, thereby preventing leakage. In addition, when the first liquid filling column 21 is accidentally collided, the first elastic member 22 can also provide a certain resistance to prevent the first liquid filling column 21 from rising and leaking.

[0070] like Figure 4 and Figure 6 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the outer peripheral wall of the first liquid-filling column 21 on the side away from the liquid storage chamber 101 is raised to form a base 211, and the first liquid-filling unit 2 also includes an elastic pad 23, which is arranged on the first liquid-filling column 21 or the housing assembly 1, and the elastic pad 23 is located between the base 211 and the bottom wall of the first installation chamber 102. Due to the provision of the elastic pad 23, when the first liquid-filling column 21 is moved from the second position to the first position under the action of the first elastic member 22 to reset, the elastic pad 23 located between the base 211 and the bottom wall of the first installation chamber 102 can play an elastic buffering role, thereby preventing the first liquid-filling column 21 from directly colliding with the bottom wall of the first installation chamber 102 and causing wear and tear.

[0071] like Figure 4 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the elastic pad 23 is sleeved on the outside of the first liquid-filled column 21. This facilitates the positioning of the elastic pad 23 and improves assembly efficiency.

[0072] like Figures 3 to 6As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: the shell assembly 1 is provided with a second through hole 104 connecting the liquid storage chamber 101 and the first installation chamber 102, and also includes an exhaust assembly 4, the exhaust assembly 4 includes an exhaust pipe 41 and an air guide column 42, the exhaust pipe 41 is arranged in the liquid storage chamber 101, the bottom end of the exhaust pipe 41 is inserted in the second through hole 104, the air guide column 42 is located in the first installation chamber 102, the air guide column 42 is arranged on the first liquid-filled column 21, and the air guide column 42 is provided with an air guide channel 401, and the air guide column 42 is configured to be able to extend and retract relative to the second through hole 104 under the drive of the first liquid-filled column 21, so that the air guide channel 401 is connected or blocked, so as to connect or interrupt the exhaust pipe 41 with the outside world. By adopting the above structure, the first liquid filling column 21 drives the movement of the air guide column 42 to realize the control of liquid injection and exhaust opening and closing respectively at the same time. The exhaust pipe 41 is located in the liquid storage chamber 101 and is inserted on the second through hole 104. The air guide column 42 is arranged on the first liquid filling column 21. Therefore, when filling, the first liquid filling column 21 moves from the first position to the second position, which will synchronously drive the air guide column 42 to move relative to the second through hole 104, so that the air guide column 42 can connect the exhaust pipe 41 with the outside world, thereby allowing the gas inside the liquid storage chamber 101 to be discharged synchronously when filling. An independent air guide channel 401 for connecting the exhaust pipe 41 with the outside world is provided on the air guide column 42, which can further ensure smooth exhaust and improve the exhaust efficiency.

Driven by the first liquid filling column 21, the air guide column 42 rises and extends into the second through hole 104, so that the air inlet 402 of the air guide channel 401 is connected to the exhaust pipe 41, so that the gas inside the liquid storage chamber 101 can be discharged synchronously during liquid filling. When liquid filling is completed, the first liquid filling column 21 returns to the second position and drives the air guide column 42 to return to its original position so that the air guide column 42 can block the second through hole 104, thereby ensuring that the liquid in the liquid storage chamber 101 does not leak. By adopting the above structure, when the air guide column 42 is extended and retracted relative to the second through hole 104 driven by the liquid filling component, the sliding cooperation between the air guide column 42 and the shell component 1 or the sealing element forms a dynamic seal on the air inlet end of the air guide channel 401, thereby realizing the control of the exhaust opening and closing.

The provision of the second sealing ring 6 can improve the sealing performance of the connection between the air guide column 42 and the second through hole 104. When the first liquid-filled column 21 is in the first position, the air guide column 42 can cooperate with the second sealing ring 6 to seal the second through hole 104, ensuring that the liquid storage chamber 101 does not leak. The tight connection between the second sealing ring 6 and the air guide column 42 can better cooperate with the telescopic movement of the air guide column 42, effectively preventing the liquid in the liquid storage chamber 101 from leaking through the connection when the air guide column 42 moves.

By adopting the above structure, when not filled with liquid, the air outlet end of the air guide channel 401 is sealed and connected to the bottom wall of the first installation cavity 102, so that the air outlet end is blocked, preventing the liquid in the liquid storage cavity 101 from entering the exhaust pipe 41 and leaking through the air guide column 42; when filled with liquid, the air guide column 42 moves toward the second through hole 104 under the drive of the first liquid filling column 21, so that the air outlet end of the air guide channel 401 is away from the bottom wall of the first installation cavity 102, so that the air outlet end is open, and a first exhaust gap 403 is formed between the air outlet end and the inner wall of the installation cavity to connect the air outlet end with the outside world, so that the gas in the liquid storage cavity 101 can be discharged through the exhaust pipe 41 and the air guide column 42 in turn, ensuring smooth filling.
