Description

Technical Field

[0001] The utility model relates to the field of perfume utensils, in particular to a liquid filling structure and a liquid filling 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 any spilled perfume, which is a complex operation. 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 filling device to allow liquid to be added to the secondary bottle.

[0003] However, there are differences between different styles of perfume bottles on the market, or even between different batches of the same style. This results in different sizes, lengths, or pump strokes of the liquid outlet nozzles of different perfume bottles, and the sub-filling bottles usually only correspond to a single type of liquid outlet nozzle. Therefore, during the filling process, liquid leakage or inability to fill may easily occur due to inability to adapt, which requires users to configure multiple corresponding matching sub-filling 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 filling structure and a liquid filling bottle to address the problem that the bottom filling structure of the liquid filling bottle in the existing technology cannot adapt to the liquid outlet nozzles of various styles and shapes of mother bottles, which requires users to configure multiple corresponding matching filling bottles, increases the user's usage costs, and causes waste of resources.

[0005] A liquid filling structure comprises: a shell assembly, the shell assembly being provided with a liquid storage cavity; a limiting portion, the limiting portion being movably arranged on the shell assembly, the limiting portion and the shell assembly being enclosed to form a mounting groove, the shell assembly being provided with a first through hole connecting the liquid storage cavity and the mounting groove; a liquid filling assembly, the liquid filling assembly comprising a liquid filling column and a liquid filling base, the liquid filling column being movably arranged in the mounting groove, the liquid filling column being capable of telescopic movement relative to the first through hole and having at least a disconnection position and a conduction position, the liquid filling column being in the disconnection position so as to interrupt the communication between the liquid storage cavity and the outside, and the liquid filling column being in the conduction position so as to connect the liquid storage cavity with the outside, the liquid filling base being sleeved on the outer circumference of the liquid filling column, the liquid filling column being configured to abut against the liquid outlet nozzle of a mother bottle directly or indirectly through the liquid filling base, and being movable from the disconnection position to the conduction position under the action of an external force; the limiting portion being adjustably assembled and connected to the shell assembly so as to allow the liquid inlet end of the liquid filling column to extend or retract into the mounting groove.

[0006] The present application provides a liquid filling structure, in which a liquid filling base is arranged on the outside of a liquid filling column, so that the liquid outlet nozzles of mother bottles of different calibers can be adaptively abutted against the liquid filling column or the liquid filling base. Specifically, when the liquid outlet nozzle is small, the liquid outlet nozzle directly abuts against the liquid inlet end of the liquid filling column. When the user presses the liquid sub-filling bottle toward the mother bottle, the liquid filling column can be moved from the disconnected position to the conductive position, so that the mother bottle can be connected to the liquid storage chamber through the liquid filling column for filling; when the liquid outlet nozzle is large, the liquid outlet nozzle abuts against the liquid filling base. When the user presses the liquid sub-filling bottle toward the mother bottle, the liquid filling base rises under the action of external force and drives the liquid filling column to move from the disconnected position to the conductive position to achieve liquid filling conduction. In addition, when idle, the liquid inlet end of the liquid filling column can be hidden in the mounting groove, thereby forming a protective effect to avoid the risk of collision and breakage. During filling, the user can adjust the assembly position of the stopper and the housing assembly as needed, thereby shortening the height of the mounting slot formed by the stopper and the housing assembly. This allows the liquid inlet end of the filling assembly to extend out of the mounting slot for easier insertion into the liquid outlet. This also prevents the wide mouth of the mother bottle from colliding with the stopper and hindering filling. This solution is more suitable for mother bottles with short liquid outlets. This solution not only makes the filling structure compact, but also can be used with a wide range of mother bottle liquid outlets of various shapes and sizes, providing convenience for users and reducing usage costs.

[0007] In one embodiment, the outer wall of one of the housing assembly and the limiting portion is provided with an external thread, and the other of the housing assembly and the limiting portion is provided with an internal thread that matches the external thread. The limiting portion is rotatably connected to the housing assembly through the cooperation of the external and internal threads to adjust the height of the mounting slot. With this structure, a user can drive the limiting portion to rotate relative to the housing assembly as needed. When the limiting portion rotates, it can rise or fall relative to the housing assembly, thereby adjusting the height of the mounting slot. This allows the liquid inlet end of the liquid filling column to extend or retract into the mounting slot, and the extension length is adjustable.

[0008] In one embodiment, the bottom wall of the liquid filling base is separately connected to the limiting part, and the liquid filling base is configured to be movable relative to the liquid filling column and along its length direction under the drive of the limiting part. By adopting the above structure, the liquid filling base can move relative to the liquid filling column, and the liquid filling base abuts against the limiting part in a natural state, so that the user can operate the limiting part as needed to make the liquid filling base rise relative to the liquid filling column. On the one hand, the liquid filling column can be exposed outside the mounting groove alone for easy insertion into the liquid outlet nozzle. When the small-diameter liquid outlet nozzle directly abuts against the liquid filling column to drive the liquid filling column to move, there is no need to drive the liquid filling base to move synchronously, making the operation easier and more labor-saving. On the other hand, the liquid filling base is closer to the first through hole under the lifting of the limiting part, so that the filling stroke can be shortened when the large-diameter liquid outlet nozzle abuts against the liquid filling base, making it more convenient to fill the mother bottle with a short liquid outlet nozzle.

[0009] In one embodiment, the device further includes a first elastic member, with its ends respectively abutting against the liquid-filling base and the inner wall of the mounting groove. When the liquid-filling base rises along the length of the liquid-filling column under an external force, the first elastic member elastically deforms to provide an elastic restoring force to reset the liquid-filling base. When liquid filling is complete and the liquid outlet nozzle leaves the supporting force on the liquid-filling base, the driving force acting on the liquid-filling base dissipates. At this point, the elastic restoring force provided by the first elastic member allows the liquid-filling base to quickly return to its original position, facilitating subsequent use.

[0010] In one embodiment, the second elastic member is sleeved on the outside of the liquid-filled column.

[0011] In one embodiment, the limiting portion protrudes toward one side of the liquid storage chamber to form a limiting ring, which is located in the installation groove, and the liquid-filled base is adapted to be installed in the limiting ring. The formation of the limiting ring can form a limiting effect on the liquid-filled base, facilitating the positioning and installation of the liquid-filled base.

[0012] In one embodiment, the liquid filling column includes a column and a first positioning plate, the column is movably arranged in the installation groove, the column can be telescopic relative to the first through hole, the liquid filling base is sleeved on the outer peripheral side of the column and can move along the length direction of the column, the first positioning plate is arranged on the outer peripheral wall of the column, and the first positioning plate is located between the liquid filling base and the bottom wall of the installation groove. By adopting the above structure, when the liquid filling column contacts the liquid outlet nozzle of the mother bottle through the liquid filling base, the liquid filling base can rise along the length direction of the column under the action of external force and contact the first positioning plate, thereby driving the liquid filling column from the disconnected position to the conductive position under the cooperation of the liquid filling base and the first positioning plate.

[0013] In one embodiment, a limiting groove is provided on the side of the liquid filling base away from the liquid storage chamber, and a second through hole is provided on the bottom wall of the limiting groove. The liquid inlet end of the column extends into the limiting groove through the second through hole and is exposed through the opening of the limiting groove. The liquid filling column also includes a second positioning plate, which is arranged on the outer peripheral wall of the column. The second positioning plate is located in the limiting groove. By adopting the above structure, the liquid outlet nozzle of the mother bottle of corresponding caliber can extend into the limiting groove and abut against the second positioning plate. Under the action of external force, the liquid outlet nozzle pushes the second positioning plate to rise and drives the liquid filling column to move from the disconnected position to the conductive position to realize liquid filling. In addition, the second positioning plate can adjust the distance between it and the limiting groove opening through the assembly connection of the limiting part and the shell assembly, thereby better adapting to the mother bottle with a short liquid outlet nozzle for liquid filling.

[0014] In one embodiment, the first positioning plate is detachably mounted on the column, thereby making it easier to assemble the liquid-filled base and the column.

[0015] In one embodiment, a second elastic member is further included, with its ends respectively abutting against the liquid-filling column and the bottom wall of the mounting slot. When the liquid-filling column moves from the disconnected position to the connected position, the second elastic member elastically deforms, providing an elastic restoring force to return the liquid-filling column to the disconnected position. When liquid filling is complete and the liquid outlet nozzle leaves the supporting force on the liquid-filling column, the driving force acting on the liquid-filling column disappears. At this point, the elastic restoring force provided by the second elastic member allows the liquid-filling column to quickly return to the disconnected position, isolating the liquid storage chamber from the outside world and effectively preventing liquid leakage from the liquid storage chamber.

[0016] In one embodiment, one end of the first elastic member away from the bottom wall of the installation groove abuts against the first positioning plate.

[0017] In one embodiment, a sealing member is further included, which is located in the liquid storage cavity. One end of the liquid filling column passes through the first through hole and is connected to the sealing member. The liquid filling column is provided with a liquid filling channel. The side wall of the liquid filling column close to the sealing member is provided with a liquid outlet hole connected to the liquid filling channel. When the liquid filling column is located at the disconnected position, the sealing member is sealed and connected to the first through hole, and the connection between the liquid outlet hole and the liquid storage cavity is interrupted. When the liquid filling column is located at the conducting position, the sealing member is separated from the side wall of the first through hole, and the liquid outlet hole connects the liquid filling channel and the liquid storage cavity. When filling liquid, by connecting the filling column at the bottom of the shell assembly with the liquid outlet nozzle of the mother bottle and pressing it downward, the liquid outlet nozzle of the mother bottle will push the filling column to rise and move from the disconnected position to the conductive position. At this time, the filling column drives the sealing member at the upper end to move upward and separate from the filling hole, so that the liquid can smoothly flow from the filling channel through the liquid outlet hole into the liquid storage cavity; and when the filling is completed, the thrust of the liquid outlet nozzle of the mother bottle disappears. At this time, under the elastic restoring force provided by the second elastic member, the filling column drives the sealing member to move downward quickly, so that the sealing member blocks the filling hole to form a sealed state. The bottom filling structure of the present application is simple, can provide convenience for production and assembly, improve production efficiency, and at the same time has good sealing effect and is easy to operate. By pressing the entire bottom filling structure back and forth toward the liquid outlet nozzle of the mother bottle, multiple fillings can be easily achieved.

[0018] A second aspect of the present application provides a liquid dispensing bottle.

[0019] A liquid dispensing bottle comprises: the above-mentioned liquid filling structure; a liquid outlet assembly, wherein the liquid outlet assembly is arranged on the shell assembly, and the liquid outlet assembly is connected to the liquid storage chamber. The liquid dispensing bottle disclosed in the second aspect of the present application, by providing any of the above-mentioned liquid filling structures, the liquid filling base is provided on the outside of the liquid filling column, so that the liquid outlet nozzles of mother bottles of different calibers can be adapted to abut against the liquid filling column or the liquid filling base for liquid filling. In addition, through the assembly connection between the limiting portion and the shell assembly, the user can adjust the assembly position of the limiting portion and the shell assembly as needed during liquid filling, thereby shortening the height of the mounting groove formed by the limiting portion and the shell assembly, allowing the liquid inlet end of the liquid filling assembly to extend out of the mounting groove for easy insertion into the liquid outlet nozzle, and avoiding the collision of the mother bottle's mouth with the limiting portion when it is too wide to hinder liquid filling, thereby better adapting to mother bottles with short liquid outlet nozzles.

[0020] In one embodiment, an exhaust component is further included. The exhaust component is arranged on the shell component and is connected to the liquid storage chamber. The gas in the liquid storage chamber is discharged through the exhaust component while the liquid is filled. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] 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.

[0041] 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.

[0042] The liquid-filled structures according to some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0043] like Figures 1 to 7 As shown, this embodiment discloses a liquid filling structure, including: a shell component 1, the shell component 1 is provided with a liquid storage cavity 101; a limiting portion 2, the limiting portion 2 is movably arranged on the shell component 1, the limiting portion 2 and the shell component 1 are enclosed to form a mounting groove 102, and the shell component 1 is provided with a first through hole 103 connecting the liquid storage cavity 101 and the mounting groove 102; a liquid filling component 3, the liquid filling component 3 includes a liquid filling column 31 and a liquid filling base 32, the liquid filling column 31 is movably arranged in the mounting groove 102, the liquid filling column 31 can be telescopic relative to the first through hole 103 and has at least The disconnected position and the connected position, when the filling column 31 is in the disconnected position, the connection between the liquid storage chamber 101 and the outside is interrupted, and when the filling column 31 is in the connected position, the liquid storage chamber 101 is connected with the outside, and the filling base 32 is sleeved on the outer peripheral side of the filling column 31, and the filling column 31 is configured to be able to directly or indirectly abut against the liquid outlet nozzle 410 of the mother bottle 400 through the filling base 32, and move from the disconnected position to the connected position under the action of external force; the limiting part 2 can be adjusted to be assembled and connected with the shell assembly 1 so that the liquid inlet end of the filling column 31 extends out of or retracts into the mounting groove 102.

[0044] The present application provides a liquid filling structure, in which the liquid filling base 32 is arranged on the outside of the liquid filling column 31, so that the liquid outlet nozzle 410 of the mother bottle 400 of different calibers can be adaptively abutted against the liquid filling column 31 or the liquid filling base 32. Specifically, when the liquid outlet nozzle 410 is small, the liquid outlet nozzle 410 directly abuts the liquid inlet end of the liquid filling column 31. When the user presses the liquid sub-filling bottle toward the mother bottle 400, the liquid filling column 31 can be moved from the disconnected position to the conductive position, so that the mother bottle 400 can be connected with the liquid storage chamber 101 through the liquid filling column 31 for liquid filling; when the liquid outlet nozzle 410 is large, the liquid outlet nozzle 410 abuts against the liquid filling base 32. When the user presses the liquid sub-filling bottle toward the mother bottle 400, the liquid filling base 32 rises under the action of external force and drives the liquid filling column 31 to move from the disconnected position to the conductive position to achieve liquid filling conduction. In addition, when not in use, the liquid inlet end of the filling column 31 can be hidden in the mounting groove 102, thereby providing protection and avoiding the risk of collision and breakage. When filling, the user can adjust the assembly position of the limiting portion 2 and the housing assembly 1 as needed, thereby shortening the height of the mounting groove 102 formed by the limiting portion 2 and the housing assembly 1, allowing the liquid inlet end of the filling assembly 3 to extend out of the mounting groove 102 for easy insertion into the liquid outlet nozzle 410, and preventing the bottle mouth 420 of the mother bottle 400 from colliding with the limiting portion 2 when it is too wide, thereby better adapting to mother bottles 400 with short liquid outlet nozzles 410. This solution can make the filling structure compact while also being widely used with mother bottles 400 liquid outlet nozzles 410 of various shapes and sizes, providing convenience for users and reducing usage costs.

[0045] like Figures 3 to 7 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines that: the outer wall of one of the housing assembly 1 and the limiting portion 2 is provided with an external thread 11, and the other of the housing assembly 1 and the limiting portion 2 is provided with an internal thread 21 that matches the external thread 11. The limiting portion 2 is rotatably connected to the housing assembly 1 through the cooperation of the external thread 11 and the internal thread 21 to adjust the height of the mounting groove 102. By adopting the above-mentioned structure, the user can drive the limiting portion 2 to rotate relative to the housing assembly 1 as needed. When the limiting portion 2 rotates, it can rise or fall relative to the housing assembly 1, thereby adjusting the height of the mounting groove 102. As a result, the liquid inlet end of the liquid filling column 31 can extend or retract into the mounting groove 102, and the extension length is adjustable.

[0046] like Figures 4 to 6As shown, in addition to the features of the above embodiments, this embodiment further defines that: the bottom wall of the liquid-filled base 32 is separately connected to the limiting portion 2, and the liquid-filled base 32 is configured to be able to move relative to the liquid-filled column 31 and along its length direction under the drive of the limiting portion 2. By adopting the above structure, the liquid filling base 32 can move relative to the liquid filling column 31, and the liquid filling base 32 abuts against the limiting part 2 in a natural state, so that the user can operate the limiting part 2 as needed to make the liquid filling base 32 rise relative to the liquid filling column 31. On the one hand, the liquid filling column 31 can be exposed alone outside the mounting groove 102 for easy insertion into the liquid outlet nozzle 410. When the small-diameter liquid outlet nozzle 410 directly abuts against the liquid filling column 31 to drive the liquid filling column 31 to move, there is no need to drive the liquid filling base 32 to move synchronously, and the operation is easier and more labor-saving. On the other hand, the liquid filling base 32 is closer to the first through hole 103 when the limiting part 2 is lifted, so that the filling stroke can be shortened when the large-diameter liquid outlet nozzle 410 abuts against the liquid filling base 32, which makes it easier to fill the short mother bottle 400 with liquid through the liquid outlet nozzle 410.

[0047] like Figures 4 to 6 As shown, in addition to the features of the above-described embodiment, this embodiment further defines: it also includes a first elastic member 4, the ends of which respectively abut against the liquid filling base 32 and the inner wall of the mounting groove 102. When the liquid filling base 32 rises along the length of the liquid filling column 31 under the action of an external force, the first elastic member 4 elastically deforms to provide an elastic restoring force to restore the liquid filling base 32. When liquid filling is completed and the liquid outlet nozzle 410 leaves the supporting force on the liquid filling base 32, the driving force on the liquid filling base 32 disappears. At this time, the elastic restoring force provided by the first elastic member 4 can quickly return to its original position and facilitate subsequent use.

[0048] like Figures 4 to 6 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the second elastic member 5 is sleeved on the outside of the liquid-filled column 31 .

[0049] like Figures 4 to 7 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the limiting portion 2 is protruded toward the liquid storage chamber 101 on one side to form a limiting ring 22, the limiting ring 22 is located in the installation groove 102, and the liquid filling base 32 is adapted to be installed in the limiting ring 22. The formation of the limiting ring 22 can form a limiting effect on the liquid filling base 32, facilitating the positioning and installation of the liquid filling base 32.

[0050] like Figures 4 to 7As shown, in addition to the features of the above embodiment, this embodiment further defines that: the liquid filling column 31 includes a column 311 and a first positioning plate 312, the column 311 is movably disposed in the mounting groove 102, the column 311 is capable of telescopic movement relative to the first through hole 103, the liquid filling base 32 is sleeved on the outer peripheral side of the column 311 and is capable of moving along the length direction of the column 311, the first positioning plate 312 is disposed on the outer peripheral wall of the column 311, and the first positioning plate 312 is located between the liquid filling base 32 and the bottom wall of the mounting groove 102. By adopting the above structure, when the liquid filling column 31 abuts the liquid outlet nozzle 410 of the mother bottle 400 through the liquid filling base 32, the liquid filling base 32 can rise along the length direction of the column 311 under the action of external force and abut against the first positioning plate 312, thereby driving the liquid filling column 31 from the disconnected position to the conductive position under the cooperation of the liquid filling base 32 and the first positioning plate 312.

[0051] like Figures 4 to 7 As shown, in addition to the features of the above-mentioned embodiments, this embodiment further defines that: a limiting groove 303 is provided on the side of the liquid-filled base 32 away from the liquid storage chamber 101, and a second through hole 304 is provided on the bottom wall of the limiting groove 303. The liquid inlet end of the column 311 extends into the limiting groove 303 through the second through hole 304 and is exposed through the opening of the limiting groove 303. The liquid-filled column 31 also includes a second positioning plate 313. The second positioning plate 313 is arranged on the outer peripheral wall of the column 311, and the second positioning plate 313 is located in the limiting groove 303. By adopting the above structure, the liquid outlet nozzle 410 of the mother bottle 400 of the corresponding caliber can be extended into the limiting groove 303 and abut against the second positioning plate 313. Under the action of external force, the liquid outlet nozzle 410 pushes the second positioning plate 313 to rise and drives the filling column 31 to move from the disconnected position to the conductive position to realize liquid filling. In addition, the second positioning plate 313 can adjust the distance between it and the opening of the limiting groove 303 through the assembly connection between the limiting part 2 and the shell assembly 1, thereby better adapting to the mother bottle 400 with a short liquid outlet nozzle 410 for liquid filling.

[0052] In addition to the features of the above embodiment, this embodiment further provides that: the first positioning plate 312 is detachably mounted on the column 311. This makes the assembly of the liquid-filled base 32 and the column 311 more convenient.

[0053] like Figures 4 to 6As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines: it also includes a second elastic member 5, the two ends of which are respectively against the liquid filling column 31 and the bottom wall of the installation groove 102. When the liquid filling column 31 moves from the disconnected position to the conductive position, the second elastic member 5 elastically deforms to provide an elastic restoring force for the liquid filling column 31 to return to the disconnected position. When the liquid filling is completed and the liquid outlet nozzle 410 leaves and the supporting force on the liquid filling column 31 disappears, the driving force on the liquid filling column 31 disappears. At this time, under the elastic restoring force provided by the second elastic member 5, the liquid filling column 31 can quickly return to the disconnected position, isolating the liquid storage chamber 101 from the outside, thereby effectively preventing liquid leakage from the liquid storage chamber 101.

[0054] like Figures 4 to 6 As shown, in addition to the features of the above embodiment, this embodiment further defines that: one end of the first elastic member 4 away from the bottom wall of the installation groove 102 abuts against the first positioning plate 312 .

[0055] like Figures 4 to 6 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: it also includes a sealing member 6, the sealing member 6 is located in the liquid storage chamber 101, one end of the liquid filling column 31 passes through the first through hole 103 and is connected to the sealing member 6, the liquid filling column 31 is provided with a liquid filling channel 301, and the side wall of the liquid filling column 31 close to the sealing member 6 is provided with a liquid outlet hole 302 connected to the liquid filling channel 301, when the liquid filling column 31 is in the disconnected position, the sealing member 6 is sealed and connected to the first through hole 103, and the connection between the liquid outlet hole 302 and the liquid storage chamber 101 is interrupted, when the liquid filling column 31 is in the conducting position, the sealing member 6 is separated from the side wall of the first through hole 103, and the liquid outlet hole 302 connects the liquid filling channel 301 and the liquid storage chamber 101. When filling with liquid, by connecting the filling column 31 at the bottom of the shell assembly 1 with the liquid outlet nozzle 410 of the mother bottle 400 and pressing it downward, the liquid outlet nozzle 410 of the mother bottle 400 will push the filling column 31 to move upward from the disconnected position to the conductive position. At this time, the filling column 31 drives the upper end seal 6 to move upward and separate from the filling hole, so that the liquid can smoothly flow from the filling channel 301 through the liquid outlet hole 302 into the liquid storage chamber 101; and when the filling is completed, the thrust of the liquid outlet nozzle 410 of the mother bottle 400 disappears. At this time, under the elastic restoring force provided by the second elastic member 5, the filling column 31 drives the seal 6 to move downward quickly, so that the seal 6 blocks the filling hole to form a sealed state. The bottom filling structure of the present application is simple, can provide convenience for production and assembly, improve production efficiency, and at the same time has a good sealing effect and is easy to operate. By pressing the entire bottom filling structure back and forth toward the liquid outlet nozzle 410 of the mother bottle 400, multiple fillings can be easily achieved.

[0056] A second aspect of the present application provides a liquid dispensing bottle.

[0057] like Figures 1 to 7As shown, this embodiment discloses a liquid dispensing bottle, comprising: the aforementioned liquid filling structure 100; a liquid outlet assembly 200, the liquid outlet assembly 200 being disposed on the housing assembly 1 and communicating with the liquid storage chamber 101. The liquid dispensing bottle disclosed in the second aspect of the present application, by disposing any of the aforementioned liquid filling structures 100, with the liquid filling base 32 disposed outside the liquid filling column 31, allows the liquid outlet nozzles 410 of mother bottles 400 of different calibers to adaptably abut against the liquid filling column 31 or the liquid filling base 32 for liquid filling. In addition, through the assembly connection between the limiting part 2 and the shell component 1, the user can adjust the assembly position of the limiting part 2 and the shell component 1 as needed when filling the liquid, so that the height of the installation groove 102 formed by the limiting part 2 and the shell component 1 can be shortened, so that the liquid inlet end of the filling component 3 extends out of the installation groove 102 for easy insertion into the liquid outlet nozzle 410, and avoids the bottle mouth 420 of the mother bottle 400 from colliding with the limiting part 2 when it is too wide to hinder the filling of the liquid, thereby better adapting to the mother bottle 400 with a shorter liquid outlet nozzle 410.
