[0016] In some embodiments, the second fixed position includes a first sliding wall and a first abutting wall, the first abutting wall being disposed at the end of the first sliding wall away from the first track groove, and the first abutting wall being located opposite to the third turning wall;

[0017] The first sliding wall is located below the first pressing position, so that the slider can reach the first sliding wall when the fixing member is released for the first time;

[0018] The second steering wall and the third steering wall are connected to each other. One end of the second steering wall connected to the third steering wall is located above the first sliding wall, so that when the fixing member is released for the first time, the slider can reach the first sliding wall and then abut against the first abutting wall.

[0019] The distance from the end of the third steering wall connected to the second steering wall to the first abutting wall is greater than the diameter of the slider, so that when the fixing member is pushed for the second time, the slider can reach the third steering wall and then abut against the second pressing position.

[0020] In some embodiments, the housing includes an outer shell and an inner shell arranged coaxially, the axial length of the inner shell is less than the axial length of the outer shell, a second receiving cavity is provided between the outer shell and the inner shell, the sleeve and the fixing member are disposed in the second receiving cavity, and the portion of the outer shell extending beyond the inner shell forms the first receiving cavity;

[0021] The inner shell has an axially penetrating third receiving cavity, which is suitable for placing a nozzle. The other end of the outer shell is also provided with a second opening, which connects to the third receiving cavity. The nozzle is suitable for being installed in the third receiving cavity after passing through the second opening, and the bottom end of the nozzle passes through the mouth of the receiving bottle.

[0022] In some embodiments, a plurality of first abutting members are provided on the outer side wall of the sleeve, and the first abutting members are arranged sequentially at intervals along the outer periphery of the sleeve;

[0023] The inner wall of the outer shell is also provided with a plurality of second abutting members, which are spaced apart along the inner circumference of the outer shell and are abutted and installed between adjacent first abutting members.

[0024] In some embodiments, the inner ring of the fastener is further provided with an inner ring wall, the inner ring wall is axially through, an elastic cavity is provided between the outer wall of the inner ring wall and the inner wall of the fastener, a third opening is provided at the end of the elastic cavity away from the locking buckle, the inner wall of the inner ring wall is adapted to abut against the outer wall of the inner shell, and the bottom of the inner ring wall is adapted to abut against the bottle mouth of the container bottle.

[0025] The elastic element is sleeved on the inner ring wall through the third opening and is located opposite to the elastic cavity. The two ends of the elastic element abut against the bottom wall of the elastic cavity and the housing, respectively.

[0026] In some embodiments, the locking buckles are spaced apart circumferentially along the fixing member, and the end of the locking buckle near the receiving bottle extends radially inward along the fixing member to form a first locking portion. The first locking portion includes a first inclined surface and a second inclined surface. The first inclined surface is located at the end of the first locking portion near the receiving bottle, and the second inclined surface is located at the end of the first locking portion away from the receiving bottle.

[0028] When the container is installed, the first inclined surface matches the third inclined surface, the bottle mouth and / or the first locking part of the container are deformed, and after the second locking part enters the interior of the first locking part, the second inclined surface matches the fourth inclined surface, and the bottle mouth and / or the first locking part of the container return to their shape, so that the bottle mouth of the container is fixedly installed on the locking buckle.

[0029] When the slider is in the second fixed position, the outer wall of the inner shell abuts against the inner wall of the bottle opening, and the inner wall of the sleeve abuts against the outer wall of the locking buckle, so that the bottle is fixedly installed on the locking buckle.

[0030] In some embodiments, when the slider is in the second fixed position, the nozzle inside the inner shell passes through the opening of the container bottle to reach the interior of the container bottle;

[0031] The container is also equipped with a squeezing element, and the bottom of the container is provided with a pressure hole, which is connected to the outside to drive the squeezing element to squeeze the solution in the container upward.

[0032] Compared with the prior art, the receiving device provided by the present invention has at least one of the following beneficial effects:

[0033] 1. When the slider is in the first fixed position, the locking buckle is located on the outside of the sleeve, and the container bottle is detachable. When the slider is in the second fixed position, the locking buckle is located on the inside of the sleeve and locks the container bottle. The container bottle is detachable and locked through the sliding cooperation between the fixing part and the sleeve, so that the container bottle can be quickly and easily installed on the shell, which facilitates the recycling of the shell and makes it convenient for customers to replace or refill the container bottle for reuse, thus greatly saving costs.

[0034] 2. The first track groove is provided with a first turning groove at the end away from the container bottle. The slider rotates along the first turning wall of the first turning groove so that the slider reaches the first pressing position. When the fixing member is released, the elastic member drives the slider along the second turning wall to reach the second fixed position. The first turning groove allows the slider to reach the second fixed position more smoothly.

[0035] 3. The end of the second track groove away from the container bottle is also provided with a second turning groove, which makes it easier for the slider to enter the second track groove more smoothly after the fixing member is pushed again, and prevents the slider from re-entering the first turning groove.

[0036] 4. When the slider is in the second fixed position, the inner shell abuts against the inner wall of the bottle opening, and the inner wall of the sleeve abuts against the outer wall of the locking buckle, so that the locking buckle and the bottle opening are fixedly installed between the sleeve and the inner shell, preventing the bottle from accidentally coming off.

[0037] 5. An elastic cavity is provided between the fixing component and the inner ring wall. The elastic component is set in the elastic cavity and sleeved on the inner ring wall to prevent the elastic component from shaking or shifting and to enhance the stability of the elastic component.

[0038] 6. The first inclined surface of the locking buckle matches the third inclined surface of the second locking part, making it easy to push the bottle mouth into the locking buckle. The second inclined surface of the locking buckle and the fourth inclined surface of the second locking part cooperate with each other, making it easy to pull out the bottle. The assembly and disassembly of the bottle is more convenient and effortless. Moreover, when the slider is in the second fixed position, the second and fourth inclined surfaces abut against each other, increasing the contact area between the locking buckle and the bottle mouth, preventing the bottle 4 from falling off.

[0057] refer to Figures 1 to 6 This invention provides a receiving device, comprising a receiving bottle 4, a housing 1, a sleeve 2, and a fixing member 3. The receiving bottle 4 communicates with the outside through a bottle opening 41. The housing 1 has a first receiving cavity 110, and a first opening 111 is provided at the bottom of the housing 1. The receiving bottle 4 is disposed in the first receiving cavity 110 through the first opening 111. The sleeve 2 is fixed to the inner side wall of the housing 1. A track groove 21 is provided on the inner side wall of the sleeve 2. The track groove 21 has a first fixing position 2111 and a second fixing position 2121, which are respectively located at opposite axial ends of the sleeve 2. The outer wall of component 3 is provided with several sliders 31, which are slidably installed in the track groove 21. The bottom of the fixing component 3 is provided with a locking buckle 32, which is suitable for locking the bottle mouth 41 of the container bottle 4. An elastic element 342 is also provided between the top of the fixing component 3 and the shell 1. When the slider 31 is located in the first fixing position 2111, the locking buckle 32 and the bottle mouth 41 of the container bottle 4 are located opposite each other on the outside of the sleeve 2, which is suitable for assembling or removing the container bottle 4. When the slider 31 is located in the second fixing position 2121, the locking buckle 32 and the bottle mouth 41 of the container bottle 4 are located opposite each other on the inside of the sleeve 2, and the container bottle 4 is fixedly installed in the locking buckle 32.

[0058] In this embodiment, when the slider 31 is located at the first fixed position 2111, the locking buckle 32 is located outside the sleeve 2, and the container bottle 4 is detachable. When the slider 31 is located at the second fixed position 2121, the locking buckle 32 is located inside the sleeve 2 and locks the container bottle 4. The container bottle 4 is detachable and locked through the sliding cooperation between the fixing member 3 and the sleeve 2, so that the container bottle 4 can be quickly and easily installed on the housing 1, which is convenient for customers to replace or refill the container bottle 4 and reuse it, thus recycling the container device and greatly saving costs.

[0059] Specifically, the fixing member 3 is provided with multiple sliders 31, which are slidably installed in the track groove 21 to strengthen the sliding connection between the fixing member 3 and the sleeve 2, preventing the fixing member 3 from accidentally separating from the sleeve 2 and causing the container bottle 4 to fall accidentally. (Reference) Figure 3 The track groove 21 includes several first track grooves 211 and second track grooves 212 arranged at intervals. The first track grooves 211 and second track grooves 212 are connected end to end. The first track grooves 211 are arranged along the axial direction of the sleeve 2, and the second track grooves 212 connect the two ends of the first track grooves 211 along the axial direction of the sleeve 2. The first fixing position 2111 is located at the end of the first track groove 211 closer to the container bottle 4, and the second fixing position 2121 is located at the end of the first track groove 211 away from the container bottle 4. In the initial state, the slider 31 is located in the first fixed position 2111, and the locking buckle 32 and the bottle mouth 41 of the container bottle 4 are located opposite each other on the outside of the sleeve body 2. At this time, the container bottle 4 is pushed upward along the inner wall of the first receiving cavity 110, so that the bottle mouth 41 of the container bottle 4 is assembled with the locking buckle 32 of the fixing member 3. Then, the container bottle 4 is pushed upward, so that the container bottle 4 pushes the fixing member 3 to slide along the first track groove 211 to the second fixed position 2121. At this time, the locking buckle 32 of the fixing member 3 abuts against the inner wall of the sleeve body 2, and the locking buckle 32 cannot be deformed, so the bottle mouth 41 of the container bottle 4 cannot be disengaged from the locking buckle 32.

[0060] When assembling the container bottle 4, first, position the bottle opening 41 towards the first opening 111 and push it into the first receiving cavity 110. Then, under the combined action of the pushing force of the container bottle 4 and the elasticity of the elastic element 342, the bottle opening 41 of the container bottle 4 contacts and locks with the locking buckle 32 of the fixing element 3. Then, push the container bottle 4, and the slider 31 of the fixing element 3 slides along the first track groove 211. The locking buckle 32 and the bottle opening 41 of the container bottle 4 enter the sleeve body 2, thus completing the assembly. When disassembling, first push the container bottle 4 upwards. The slider 31 of the fixing element 3 continues to slide along the second track groove 212. The locking buckle 32 and the bottle opening 41 of the container bottle 4 leave the sleeve body 2. Pull the container bottle 4 again to separate the bottle opening 41 of the container bottle 4 from the locking buckle 32. In this embodiment, the container bottle 4 is pushed so that the bottle mouth 41 of the container bottle 4 is assembled with the locking buckle 32 of the fixing member 3 and pushed to fix and rotate. In a modified embodiment, a driving block can also be provided on the fixing member 3. The driving block axially passes through the sleeve 2 and the shell 1 to reach the outside. The fixing member 3 can be manually pulled by the driving block. These are all things that are easy for those skilled in the art to think of and are all within the protection scope of this application.

[0061] It is worth noting that after disassembling the container bottle 4, it can be refilled with solution and then reassembled onto the fixing member 3, or a new container bottle 4 can be replaced and reassembled. The elastic member 342 includes, but is not limited to, springs, highly elastic rubber, etc. The slider 31 is cylindrical, which facilitates its sliding within the track groove 21. The first track groove 211 is set along the axial direction of the sleeve 2 so that when the container bottle 4 is pushed for the first time, the locking buckle 32 can easily lock with the bottle mouth 41 of the container bottle 4. Of course, the first track groove 211 can also be set at an angle. In this application, the main function of the sleeve 2 is to set the track groove 21 and facilitate the assembly of the fixing member 3. First, the fixing member 3 is assembled onto the sleeve 2, and then the sleeve 2 with the fixing member 3 is fixed inside the shell 1. In another modified embodiment, the sleeve 2 and the shell 1 can also be integrated, that is, the sleeve 2 is formed on the inner side wall of the shell 1, or the track groove 21 is directly set on the inner side wall of the shell 1, and the fixing member 3 is then assembled inside the shell 1. At the same time, whether the container bottle 4 rotates when the fixing member 3 rotates is not further limited in this application.

[0062] Further, refer to Figure 7The track groove 21 also includes a first turning groove 213, which includes a first turning wall 2131, a first pressing position 2132, and a second turning wall 2133. The first pressing position 2132 is located at the end of the first track groove 211 away from the container bottle 4 and is positioned above the second fixed position 2121. The first turning wall 2131 connects the first track groove 211 and the first pressing position 2132, and the second turning wall 2133 connects the first pressing position 2132 and the first fixed position 2111. By pushing the fixing member 3 upward, the fixing member 3 squeezes the elastic member 342, and the slider 31 slides along the first track groove 211 to the end of the first track groove 211. Then, the slider 31 slides along the first turning wall 2131 and drives the fixing member 3 to rotate. The slider 31 is finally fixed and abuts against the first pressing position 2132. After the fixing member 3 is released, the elastic member 342 releases its elasticity and drives the slider 31 to slide along the second turning wall 2133 and reach the second fixed position 2121.

[0063] In this embodiment, the first track groove 211 is provided with a first turning groove 213 at the end away from the container bottle 4. The slider 31 rotates along the first turning wall 2131 of the first turning groove 213 so that the slider 31 reaches the first pressing position 2132. When the fixing member 3 is released, the elastic member 342 drives the slider 31 to reach the second fixed position 2121 along the second turning wall 2133. The first turning groove 213 makes the slider 31 reach the second fixed position 2121 more smoothly.

[0064] Specifically, the second fixing position 2121 includes a first sliding wall 21211 and a first abutting wall 21212. The first abutting wall 21212 is located at the end of the first sliding wall 21211 away from the first track groove 211, and is positioned below the third turning wall 2141. The first sliding wall 21211 is positioned below the first pressing position 2132, so that the slider 31 can reach the first sliding wall 21211 when the fixing member 3 is released for the first time. The end of the first turning wall 2131 is positioned between the beginning of the first sliding wall 21211 and the first abutting wall 21212, to prevent the slider 31 from re-entering the first track groove 211 after the fixing member 3 is released. Meanwhile, the end of the second turning wall 2133 away from the first pressing position 2132 must also be located on the first sliding wall 21211 and not exceed the first abutting wall 21212. That is, the end of the second turning wall 2133 is located on one side of the first abutting wall 21212. Moreover, the distance between the end of the second turning wall 2133 away from the first pressing position 2132 and the first abutting wall 21212 should be greater than the diameter of the slider 31, so that there is a gap between the end of the second turning wall 2133 and the first abutting wall 21212 for the slider 31 to pass through. When the fixing member 3 is pushed again, the slider 31 passes through the gap between the end of the second turning wall 2133 and the first abutting wall 21212. The slider 31 will not re-enter the first turning wall 2131, thus preventing the slider 31 from always being locked at the second fixing position 2121, which would prevent the container bottle 4 from being disassembled.

[0065] It is worth noting that the main function of the first pressing position 2132 in this application is to misalign the slider 31 with the first track groove 211, so that the slider 31 will not enter the first track groove 211 after the fixing member 3 is released. The first pressing position 2132 can be set horizontally or at an angle, as long as the end of the first pressing position 2132 away from the first turning wall 2131 is located on the first sliding wall 21211, and the distance from the end of the first pressing position 2132 away from the first turning wall 2131 to the head end of the first sliding wall 21211 is greater than the diameter of the slider 31.

[0066] In a modified embodiment, the first steering groove 213 includes only a first steering wall 2131 and a second steering wall 2133, with the first steering wall 2131 and the second steering wall 2133 forming a certain angle and slidingly engaging with the angle between the first steering wall 2131 and the second steering wall 2133.

[0067] Furthermore, the track groove 21 also includes a second turning groove 214, which includes a third turning wall 2141, a second pressing position 2142, and a fourth turning wall 2143. The second pressing position 2142 is located at the end of the second track groove 212 away from the container bottle 4 and is positioned above the second fixing position 2121. The third turning wall 2141 connects the second fixing position 2121 and the second pressing position 2142, and the fourth turning wall 2143 connects the second pressing position 2142 and the second track groove 212.

[0068] In this embodiment, a second turning groove 214 is provided at the end of the second track groove 212 away from the container bottle 4, so that after the fixing member 3 is pushed again, the slider 31 can enter the second track groove 212 more smoothly, preventing the slider 31 from re-entering the first turning groove 213.

[0069] Specifically, when the fixing member 3 is pushed upward again, the fixing member 3 compresses the elastic member 342, and the slider 31 slides along the third turning wall 2141 and drives the fixing member 3 to rotate. The slider 31 eventually reaches the second pressing position 2142. After the fixing member 3 is released, the elastic member 342 releases its elasticity and drives the slider 31 to slide along the fourth turning wall 2143 into the second track groove 212. Then, the slider 31 slides through the second track groove 212 to the first fixing position 2111. The distance from the first end of the third turning wall 2141 to the first abutting wall 21212 is greater than the diameter of the slider 31, so that when the fixing member 3 is pushed upward for the second time, the slider 31 can reach the third turning wall 2141 and then abut against the second pressing position 2142. Preferably, the second turning wall 2133 and the third turning wall 2141 are interconnected. It is only necessary to control that the distance from the connection point of the second turning wall 2133 and the third turning wall 2141 to the first abutting wall 21212 is greater than the diameter of the slider 31. One end of the second steering wall 2133, connected to the third steering wall 2141, is positioned above the first sliding wall 21211, allowing the slider 31 to reach the first sliding wall 21211 and then abut against the first abutment wall 21212 when the fixing member 3 is released for the first time. One end of the second pressing position 2142, connected to the fourth steering wall 2143, is positioned above the second track groove 212, allowing the slider 31 to slide only into the second track groove 212 when the fixing member 3 is released again. The second pressing position 2142 has the same function as the first pressing position 2132, and will not be further described in this application.

[0070] Further, refer to Figure 4 and Figure 10The housing 1 includes an outer shell 11 and an inner shell 12 arranged coaxially. The axial length of the inner shell 12 is less than the axial length of the outer shell 11. A second receiving cavity 112 is provided between the outer shell 11 and the inner shell 12. The sleeve 2 and the fixing member 3 are disposed in the second receiving cavity 112. The portion of the outer shell 11 that extends beyond the inner shell 12 forms a first receiving cavity 110. The inner shell 12 is provided with a third receiving cavity 121 that extends axially. The third receiving cavity 121 is suitable for placing a nozzle 122. The other end of the outer shell 11 is also provided with a second opening 113 that connects to the third receiving cavity 121. The nozzle 122 is suitable for being installed in the third receiving cavity 121 after passing through the second opening 113. The bottom end of the nozzle 122 passes through the bottle mouth 41 of the receiving bottle 4.

[0071] In this embodiment, when the slider 31 is in the second fixed position 2121, the inner shell 12 abuts against the inner wall of the bottle opening 41 of the container bottle 4, and the inner wall of the sleeve 2 abuts against the outer wall of the locking buckle 32, so that the locking buckle 32 and the bottle opening 41 of the container bottle 4 are fixedly installed between the sleeve 2 and the inner shell 12, so as to prevent the container bottle 4 from accidentally falling off.

[0072] Specifically, a protective film may be provided at the mouth 41 of the container bottle 4. During assembly, the inner shell 12 and / or the nozzle 122 puncture the protective film, allowing the nozzle 122 to contact the solution inside the container bottle 4. The nozzle 122 is fixedly installed in the third receiving cavity 121 of the inner shell 12, abutting against the inner wall of the inner shell 12. Simultaneously, the inner shell 12 extends into the mouth 41 and abuts against the inner wall of the mouth 41, preventing liquid leakage from the container bottle 4 after installation. Of course, the nozzle 122 can also directly abut against the inner wall of the mouth 41, but proper fixing and leak-proof measures are required for the nozzle 122. When the slider 31 is in the second fixed position 2121, the nozzle 122 inside the inner shell 12 passes through the mouth 41 of the container bottle 4 and reaches the interior of the container bottle 4. The container bottle 4 is also provided with a squeezing member 42, and a pressure hole 43 is provided at the bottom of the container bottle 4. The pressure hole 43 is connected to the outside to drive the squeezing member 42 to squeeze the solution inside the container bottle 4 upward. The extruder 42 presses the solution upwards under atmospheric pressure, ensuring that the nozzle 122 is always in contact with the solution and that the solution in the container 4 is fully utilized. Preferably, the axial length of the inner shell 12 is the same as the axial length of the sleeve 2, so that the outer wall of the inner shell 12 and the inner wall of the sleeve 2 can simultaneously and synchronously press the locking buckle 32 of the fixing member 3 and the bottle opening 41 of the container 4, making it easier for the container 4 to enter the inner side of the sleeve 2. The nozzle 122 is prior art in this application and will not be described further.

[0073] In a modified embodiment, the nozzle 122 is fixedly installed on the end of the housing 11 away from the first opening 111. The nozzle 122 directly reaches the bottle mouth 41 of the container bottle 4 through the axial middle of the first opening 111 and the fixing member 3. At this time, the inner side wall of the bottle mouth 41 abuts against the outer side wall of the nozzle 122. That is, in this embodiment, the bottle mouth 41 is squeezed and locked by the sleeve 2 and the nozzle 122.

[0074] Further, refer to Figure 3 and Figure 10 The outer wall of the sleeve 2 has several first abutment members 22, which are arranged at intervals along the outer periphery of the sleeve 2. The inner wall of the outer shell 11 also has several second abutment members 114, which are arranged at intervals along the inner periphery of the outer shell 11. The second abutment members 114 are abutted and installed between adjacent first abutment members 22 to prevent the sleeve 2 from rotating when the container bottle 4 is pressed. It is worth noting that in modified embodiments, the sleeve 2 can also be installed on the outer shell 11 by means of screws, glue or other fixing structures. These are all things that are easy for those skilled in the art to think of, and will not be described further in this application.

[0075] Further, refer to Figure 8 The inner ring of the fastener 3 is also provided with an inner ring wall 33, which is axially through the middle. An elastic cavity 34 is provided between the outer side wall of the inner ring wall 33 and the inner side wall of the fastener 3. A third opening 341 is provided at the end of the elastic cavity 34 away from the locking buckle 32. The inner side wall of the inner ring wall 33 is adapted to abut against the outer side wall of the inner shell 12. The bottom of the inner ring wall 33 is adapted to abut against the bottle mouth 41 of the receiving bottle 4. The elastic member 342 is sleeved on the inner ring wall 33 through the third opening 341 and is located in the elastic cavity 34. The two ends of the elastic member 342 abut against the bottom wall of the elastic cavity 34 and the shell 1, respectively.

[0076] In this embodiment, an elastic cavity 34 is provided between the fixing member 3 and the inner ring wall 33. The elastic member 342 is disposed in the elastic cavity 34 and sleeved on the inner ring wall 33 to prevent the elastic member 342 from shaking or shifting and to enhance the stability of the elastic member 342.

[0077] Further, refer to Figure 6 and Figure 9 Locking buckles 32 are spaced apart circumferentially along the fixing member 3. The end of the locking buckle 32 near the receiving bottle 4 extends radially inward along the fixing member 3 to form a first locking part 321. The first locking part 321 includes a first inclined surface 3211 and a second inclined surface 3212. The first inclined surface 3211 is located at the end of the first locking part 321 near the receiving bottle 4, and the second inclined surface 3212 is located at the end of the first locking part 321 away from the receiving bottle 4. The outer side of the bottle mouth 41 of the receiving bottle 4 extends radially outward along the receiving bottle 4 to form a second locking part 411. The second locking part 411 includes a third inclined surface 4111 and a fourth inclined surface 4112. The third inclined surface 4111 is located at the end of the second locking part 411 near the fixing member 3, and the fourth inclined surface 4112 is located at the end of the second locking part 411 away from the fixing member 3.

[0078] In this embodiment, the first inclined surface 3211 of the locking buckle 32 matches the third inclined surface 4111 of the second locking part 411, which facilitates pushing the bottle mouth 41 of the container bottle 4 into the locking buckle 32. The second inclined surface 3212 of the locking buckle 32 cooperates with the fourth inclined surface 4112 of the second locking part 411, which also facilitates pulling out the container bottle 4. The assembly and disassembly of the container bottle 4 are more convenient and less strenuous. Moreover, when the slider 31 is in the second fixed position, the second inclined surface 3212 and the fourth inclined surface 4112 abut against each other, increasing the contact area between the locking buckle 32 and the bottle mouth 41, and preventing the container bottle 4 from falling.

[0079] Specifically, when installing the container bottle 4, the first inclined surface 3211 matches the third inclined surface 4111, and the bottle mouth 41 and / or the first locking part 321 of the container bottle 4 deform. After the second locking part 411 enters the interior of the first locking part 321, the second inclined surface 3212 matches the fourth inclined surface 4112, and the bottle mouth 41 and / or the first locking part 321 of the container bottle 4 return to their shape, so that the bottle mouth 41 of the container bottle 4 is fixedly installed on the locking buckle 32. When the slider 31 is in the second fixed position 2121, the outer wall of the inner shell 12 abuts against the inner wall of the bottle mouth 41 of the container bottle 4, and the inner wall of the sleeve 2 abuts against the outer wall of the locking buckle 32, so that the container bottle 4 is fixedly installed on the locking buckle 32. The second inclined surface 3212 and the fourth inclined surface 4112 abut against each other, increasing the contact area between the locking buckle 32 and the bottle mouth 41, thereby increasing the friction between the locking buckle 32 and the bottle mouth 41 and preventing the container bottle 4 from falling off. Furthermore, the first locking part 321 also includes a first flat surface, which connects the first inclined surface 3211 and the second inclined surface 3212. The second locking part 411 also includes a second flat surface, which connects the third inclined surface 4111 and the fourth inclined surface 4112. During the installation and removal of the container bottle 4, the first flat surface is adapted to abut against the second flat surface to avoid wear at the connection between the first inclined surface 3211 and the second inclined surface 3212, and at the connection between the third inclined surface 4111 and the fourth inclined surface 4112, which would reduce the locking force of the first locking part 321 and the second locking part 411 and ensure smooth and effective contact between the first locking part 321 and the second locking part 411.

[0080] It is worth noting that the cooperation between the first locking part 321 and the second locking part 411 can be either the locking buckle 32 deforming outward, or the bottle mouth 41 of the container bottle 4 deforming inward, or both. The inner shell 12 of this application is adapted to abut against the inner wall of the bottle mouth 41 of the container bottle 4, and the inner wall of the sleeve 2 is adapted to abut against the outer wall of the locking buckle 32. That is, the inner shell 12 and the sleeve 2 together provide the locking force for the mutual engagement of the first locking part 321 and the second locking part 411, ensuring that the container bottle 4 does not fall off when the slider 31 is in the second fixed position 2121. In this embodiment, the locking buckle 32 is made of a deformable material, while the bottle opening 41 of the container bottle 4 is made of a hard, non-deformable material. Initially, the locking buckle 32 is open, and the bottle opening 41 moves along the outer wall of the inner shell 12. The bottle opening 41 preferentially abuts against the bottom of the inner ring wall 33 and pushes the fixing member 3 upwards. At this time, the inner wall of the sleeve 2 abuts against the outer wall of the locking buckle 32 and pushes the locking buckle 32 closer to the second locking part 411 of the bottle opening 41, so that the second locking part 411 locks against the first locking part 321, and the locking buckle 32 and the bottle opening 41 are fixed between the sleeve 2 and the inner shell 12. Other embodiments are not further described in this application.

[0081] In a modified embodiment, the first locking part 321 may also be disposed on the outer wall of the locking buckle 32, and the second locking part 411 may be disposed on the inner wall of the bottle mouth 41 of the accommodating bottle 4. In this case, the inner shell 12 is adapted to abut against the inner wall of the locking buckle 32, and the sleeve 2 is adapted to abut against the outer wall of the bottle mouth 41 of the accommodating bottle 4.

[0082] In another variation, the container bottle 4 can also be an ordinary bottle. The outer wall of the bottle mouth 41 of the container bottle 4 directly abuts against the inner wall of the locking buckle 32 of the fastener 3. When the container bottle 4 is pushed upward, the inner wall of the sleeve 2 abuts against the outer wall of the locking buckle 32, and the outer wall of the inner shell 12 abuts against the inner wall of the bottle mouth 41, so that the bottle mouth 41 and the locking buckle 32 are squeezed between the sleeve 2 and the inner shell 12. In this variation, the mutual squeezing force between the sleeve 2 and the inner shell 12 is directly used to lock the bottle mouth 41 and the locking buckle 32 between the sleeve 2 and the inner shell 12.

[0083] It should be noted that the above embodiments can be freely combined as needed. The above are merely preferred embodiments of the present invention. It should be pointed out that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
