Description

Technical Field

[0001] The present invention relates to the technical field of cosmetic containers, and particularly relates to a replaceable inner cup type cosmetic container. Background Art

[0002] As the topics related to environmental protection and sustainable development have received increasing attention. The environmental protection concept of sustainable development has also penetrated into the cosmetic field. Many domestic brands have launched environmentally friendly packaging and refills, making positive progress towards sustainable development. The emergence of refills not only saves a large amount of material resources, but also brings certain price discounts to consumers due to their more environmentally friendly and lightweight characteristics compared to bottled products.

[0003] For example, the Chinese patent with the authorization announcement number CN213849201U and the authorization announcement date of August 3, 2021 discloses "A Replaceable Inner Cup Type Cream Container", which includes an outer bottle body, a bottle cap, and a replaceable inner cup disposed inside the outer bottle body. After the inner cup is installed, it can be screwed and fixed with the outer bottle body.

[0004] During the installation process of the inner cup of this patent, the inner cup is sleeved on the circumferential side of the outer bottle body (the part above the screwed external thread) through the annular ring at the top edge of the inner cup, and the circumferential side of the upper end of the inner cup abuts against the inner wall of the outer bottle body, so as to position the installation of the inner cup. However, during the installation process, the contact area between the inner cup and the outer bottle body (the part above the screwed external thread) is relatively large, and the inner cup needs to be rotated to be screwed and fixed with the outer bottle body, resulting in a relatively large frictional force on the inner cup during the installation process, thus affecting the smoothness of the inner cup installation process. Summary of the Invention

[0005] The purpose of the present invention is to provide a replaceable inner cup type cosmetic container, which has the effect of improving the installation smoothness.

[0006] The above technical object of the present invention is achieved by the following technical solutions: A replaceable inner cup type cosmetic container, including a bottle body with an accommodation cavity inside, a replaceable inner cup that can be replaceably arranged in the accommodation cavity of the bottle body, and a bottle cap threadedly connected to the bottle body. The top of the outer wall of the bottle body is provided with a tightening external thread, and the inner wall of the bottle cap is provided with a tightening internal thread that matches the tightening external thread. After the bottle cap is installed, it presses against the top of the replaceable inner cup. The replaceable inner cup includes an inner container and a handle cover embedded at the top of the inner container. The top edge of the inner container is integrally provided with a first annular ring for resting on the upper surface of the bottle body. A plurality of positioning strips for pressing against the inner wall of the accommodation cavity are circumferentially arranged between the circumferential side of the top of the inner container and the first annular ring. Two downwardly extending arc-shaped pieces are symmetrically arranged on the first annular ring. The inner wall of the arc-shaped piece is provided with a fastening strip and fastening protrusions spaced from the fastening strip; A notch is provided at the tightening external thread of the outer wall of the bottle body for the arc-shaped piece of the replaceable inner cup to be embedded from top to bottom and rotatable. A first movable groove for the fastening strip and the fastening protrusion to be embedded from top to bottom is provided on the notch. A first fastening groove communicated with the first movable groove and for the fastening strip and the fastening protrusion to be embedded during the rotation of the replaceable inner cup is provided on the notch. A fastening convex rib that is embedded between the fastening strip and the fastening protrusion when the replaceable inner cup is installed in place is provided on the first fastening groove.

[0007] By adopting the above technical solutions, when installing the replaceable inner cup, first align the two arc-shaped pieces of the replaceable inner cup with the two notches of the bottle body, and press the replaceable inner cup downward into the accommodation cavity of the bottle body. During this process, the fastening strip and the fastening protrusion are embedded in the first movable groove from top to bottom, and a plurality of positioning strips abut against the inner wall of the accommodation cavity. Then rotate the replaceable inner cup so that the fastening strip and the fastening protrusion are embedded in the second sliding groove. During this process, due to the deformation of the arc-shaped piece, the fastening convex rib is embedded between the fastening strip and the fastening protrusion; Finally, during the installation process of the replaceable inner cup, because the contact area between the positioning strip, the fastening piece and the bottle body is small, the friction force received is small. At the same time, during the process of the fastening convex rib being embedded between the fastening strip and the fastening protrusion, the arc-shaped positioning protrusion needs to pass through the fastening convex rib during the deformation process of the arc-shaped piece, and a sound will be made during this process to feedback to the user that the installation is in place. Therefore, it has the effect of improving the smoothness of the installation of the replaceable inner cup; At the same time, the notch for the arc-shaped piece to move is arranged on the tightening external thread. Compared with the design in the comparative document where the notch is arranged above the tightening external thread, it will not affect the required depth when designing the bottle cap, so as to ensure that the height of the bottle cap and the height of the bottle body are maintained in a suitable proportion.

[0008] A further setting of the present invention is that two positioning protrusions are provided at the top of the bottle body, and a positioning groove is provided on the lower surface of the first annular ring, which is embedded in the positioning protrusion when the replacement inner cup is installed in place. During the process when the positioning protrusion is not embedded in the positioning groove, the deformation at the arc-shaped piece enables the fastening strip and the fastening protrusion to be embedded in the first fastening groove during the rotation of the replacement inner cup.

[0009] By adopting the above technical solution, by providing positioning protrusions at the top of the bottle body and corresponding positioning grooves on the lower surface of the first annular ring of the replacement inner cup, the installation of the replacement inner cup is further positioned; at the same time, when the fastening strip and the fastening protrusion are in the first movable groove, the setting of the positioning protrusion enables a gap to exist between the first annular ring and the upper surface of the bottle body. At this time, the positioning groove is separated from the inner wall of the accommodating cavity, so as to reduce the friction during the process of taking out the replacement inner cup, which has the effect of facilitating the taking out of the replacement inner cup.

[0010] A further setting of the present invention is that the periphery of the inner container is spaced from the inner wall of the accommodating cavity, and the bottom of the inner container is spaced from the bottom of the accommodating cavity.

[0011] By adopting the above technical solution, after the inner container of the replacement inner cup is installed, since the periphery of the inner container is spaced from the inner wall of the accommodating cavity and the bottom of the inner container is spaced from the bottom of the accommodating cavity, the space formed between the two has the effects of heat preservation and heat insulation.

[0012] A further setting of the present invention is that an annular groove is provided at the connection between the inner wall and the upper surface of the inner container, a second annular ring is integrally provided on the periphery of the handle cover and is embedded in the annular groove, and an annular protrusion is integrally provided on the periphery of the handle cover and abuts against the inner wall of the inner container when the handle cover is installed in place.

[0013] By adopting the above technical solution, the setting of the annular groove of the inner container and the second annular ring of the handle cover can realize the positioning of the installation of the handle cover. The annular protrusion on the periphery of the handle cover abuts against the inner wall of the inner container when the handle cover is installed in place, so as to slightly fix the installed handle cover through the frictional force and avoid the situation that the handle cover directly falls off without external force.

[0014] A further setting of the present invention is that the bottle cap includes an outer cover, an inner cover adhesively provided in the outer cover and having a screwed-in internal thread, and a sealing gasket embedded in the inner cover and pressing on the replacement inner cup during the installation of the bottle cap; a plurality of anti-slip strips are circumferentially and arrayed on the periphery of the inner cover and abut against the inner wall of the outer cover during the process of being embedded in the outer cover. A glue injection groove is provided on the upper surface of the inner cover, a glue injection hole communicating with the glue injection groove is provided on the inner cover, a partition ring is provided in the glue injection groove and abuts against the inside of the outer cover after the inner cover is installed, the glue injection hole is located within the partition ring, and a fixed glue layer is formed between the inner cover and the outer cover after the glue injection solidifies.

[0015] By adopting the above technical solution, during the process of embedding the inner cover into the outer cover, multiple circumferentially arrayed anti-slip strips can achieve firm pressing and fixing against the inner wall of the outer cover, and the frictional resistance during the process of embedding the inner cover into the outer cover will not be too large; and by providing the glue injection groove and the glue injection hole, after injecting the glue, the outer cover and the inner cover can be adhesively fixed, and the setting of the partition ring can prevent the glue from overflowing from the connection gap between the inner cover and the outer cover during the glue injection process.

[0016] A further setting of the present invention is that: at the bottom of the accommodating cavity, there is an ejecting mechanism for driving the replacement inner cup to move upward when the buckling strip and the buckling protrusion are in the first moving groove; at the bottom of the accommodating cavity, there is a first installation groove, and the ejecting mechanism includes an ejecting sleeve telescopically arranged in the first installation groove and a driving component for driving the ejecting sleeve to move upward to drive the replacement inner cup to move upward.

[0017] By adopting the above technical solution, the replacement inner cup is rotationally buckled and fixed after being pressed downward. The operations of pressing the replacement inner cup downward and rotating the knob are both relatively convenient. However, when taking out the replacement inner cup, the operation of rotating the replacement inner cup is relatively convenient, but taking out the replacement inner cup is relatively laborious. Therefore, an ejecting mechanism is provided to drive the ejecting sleeve located in the first moving groove to move upward through the driving component, thereby having the effect of facilitating the removal of the replacement inner cup.

[0018] A further setting of the present invention is that: a regular polygon groove is provided at the top of the ejecting sleeve, and a regular polygon part embedded in the regular polygon groove is provided at the bottom of the replacement inner cup. The driving component includes a mounting plate adhesively arranged at the bottom of the first installation groove, a connecting ring, and a first compression spring fixedly arranged between the connecting rings of the mounting plate. The bottom of the ejecting sleeve is rotatably connected to the middle of the connecting ring. A plurality of second moving grooves extending in the vertically downward direction are provided on the inner wall of the first installation groove. A second buckling groove communicating with the bottom of the second moving groove and extending in the horizontal direction is provided on the inner wall of the first installation groove. A buckling block is provided on the circumferential side of the ejecting sleeve. During the process of pressing the replacement inner cup downward and rotationally buckling it, the buckling block moves downward along the second moving groove and rotates along the second buckling groove and then buckles.

[0019] By adopting the above technical solution, during the process of pressing down and rotating and buckling the replacement inner cup, the buckling block moves downward along the second moving groove and rotates along the second buckling groove and then buckles, so that the ejecting sleeve can be buckled in the second buckling groove of the first installation groove for limiting, and no continuous acting force is applied to the bottom of the replacement inner cup, so as to avoid deformation of the bottom of the replacement inner cup. At this time, the wall thickness of the replacement inner cup can also be thinner during design, avoiding excessive material waste and conforming to the environmental protection concept; at the same time, when the buckling strip and the buckling protrusion are in the first moving groove, the buckling block also rotates into the second moving groove. At this time, through the elastic force of the first compression spring, the ejecting sleeve can be driven to move upward, thereby driving the replacement inner cup to move upward to facilitate the removal of the replacement inner cup.

[0020] The further setting of the present invention is that: the first installation groove is square, the bottom of the bottle body is provided with a second installation groove that communicates with the first installation groove and has a "convex" cross-section, the driving assembly includes a knob arranged in the second installation groove and having a bottom flush with the bottom surface of the bottle body, a connecting plate telescopically arranged in the first installation groove, a rotating shaft arranged on the knob and passing through the connecting plate, a second compression spring arranged at one end of the rotating shaft passing through the connecting plate, an anti-detachment end cover arranged at the upper end of the rotating shaft to prevent the second compression spring from falling off, and a linkage member arranged between the connecting plate and the knob and driving the connecting plate to move upward against the elastic force of the second compression spring during the rotation of the knob, the ejecting sleeve is arranged on the connecting plate and drives the replacement inner cup to move upward during the upward movement of the connecting plate.

[0021] By adopting the above technical solution, similarly, due to the setting of the driving assembly, no continuous acting force is applied to the top of the replacement inner cup when not working, so as to avoid deformation of the bottom of the replacement inner cup; when it is necessary to eject the replacement inner cup upward, by rotating the knob, the linkage member drives the connecting plate to move upward against the elastic force of the second compression spring, driving the ejecting sleeve to drive the replacement inner cup to move upward.

[0022] The further setting of the present invention is that: the linkage member includes a first linkage ring arranged on the upper surface of the knob and surrounding the rotating shaft, and a second linkage ring arranged on the lower surface of the connecting plate and surrounding the rotating shaft, the upper surface of the first linkage ring is an inclined surface, and the lower surface of the second linkage ring is matched with the upper surface of the first linkage ring.

[0023] By adopting the above technical solution, the linkage member includes a first linkage ring and a second linkage ring. At this time, during the process of the knob rotating one circle against the elastic force of the second compression spring, the function of automatically resetting after the ejecting sleeve moves upward is realized. While facilitating the ejection of the replacement inner cup, no resistance is generated to the installation of the replacement inner cup.

[0024] A further setting of the present invention is that: a third installation groove which is communicated with the second installation groove and has a "convex" cross-section is provided at the bottom of the bottle body. The driving assembly includes a flexible bladder embedded in the third installation groove and having a lower surface flush with the lower surface of the bottle body, an airbag provided in the first installation groove and adhered to the ejecting sleeve, and an air pipe provided between the airbag and the flexible bladder. During the process of pressing the flexible bladder, the airbag inflates and expands to drive the ejecting sleeve to move upward. When the flexible bladder is released, the flexible bladder gradually recovers its deformation.

[0025] By adopting the above technical solution, when it is necessary to drive the ejecting sleeve to move upward, by pressing the flexible bladder, the airbag inflates and expands to drive the ejecting sleeve to move upward. When the flexible bladder is released, the flexible bladder will gradually recover its deformation. And during the installation process of the new replacement inner cup, by squeezing the inflated airbag, the gas can also flow back into the flexible bladder, enabling the flexible bladder to quickly recover its deformation.

Detailed Description of the Invention

[0041] The present invention will be further described in detail below with reference to the accompanying drawings.

[0042] Embodiment 1: A replaceable inner cup type cosmetic container, as Figures 1 to 3 shown, includes a bottle body 1 with an accommodation cavity 11 inside, a replaceable inner cup 2 that can be replaceably arranged in the accommodation cavity 11 of the bottle body 1, and a bottle cap 3 threadedly connected to the bottle body 1. A screwing external thread 12 is provided at the top of the outer wall of the bottle body 1, and a screwing internal thread 321 that matches the screwing external thread 12 is provided on the inner wall of the bottle cap 3. After the bottle cap 3 is installed, it presses against the top of the replaceable inner cup 2.

[0043] As Figures 2 to 5As shown in the figure, the replaceable inner cup 2 includes an inner container 21 and a handle cover 22 embedded at the top of the inner container 21. At the top edge of the inner container 21, a first annular ring 211 is integrally provided for resting on the upper surface of the bottle body 1. Between the circumferential side of the top of the inner container 21 and the first annular ring 211, a plurality of positioning strips 212 for pressing against the inner wall of the receiving cavity 11 are arranged in a circumferential array. On the first annular ring 211, two downwardly extending arc-shaped pieces 213 are symmetrically provided. On the inner wall of the arc-shaped piece 213, a fastening strip 214 and a fastening protrusion 215 spaced from the fastening strip 214 are provided. At the externally threaded tightening part 12 on the outer wall of the bottle body 1, a notch 13 is provided for the arc-shaped piece 213 of the replaceable inner cup 2 to be embedded from top to bottom and rotatable. On the notch 13, a first movable groove 131 for the fastening strip 214 and the fastening protrusion 215 to be embedded from top to bottom is provided. On the notch 13, a first fastening groove 132 communicating with the first movable groove 131 and for the fastening strip 214 and the fastening protrusion 215 to be embedded during the rotation of the replaceable inner cup 2 is provided. On the first fastening groove 132, a fastening ridge 133 for being embedded between the fastening strip 214 and the fastening protrusion 215 when the replaceable inner cup 2 is installed in place is provided.

[0044] As Figure 4 and Figure 5 shown in the figure, two positioning protrusions 14 are provided at the top of the bottle body 1. On the lower surface of the first annular ring 211, a positioning groove 216 for being embedded in the positioning protrusion 14 when the replaceable inner cup 2 is installed in place is provided. During the process when the positioning protrusion 14 is not embedded in the positioning groove 216, through the deformation at the arc-shaped piece 213, the fastening strip 214 and the fastening protrusion 215 can be embedded into the first fastening groove 132 during the rotation of the replaceable inner cup 2. There is a gap between the circumferential side of the inner container 21 and the inner wall of the receiving cavity 11, and there is a gap between the bottom of the inner container 21 and the bottom of the receiving cavity 11.

[0045] As Figure 5 and Figure 6 shown in the figure, at the connection between the inner wall and the upper surface of the inner container 21, an annular groove 217 is provided. On the circumferential side of the handle cover 22, a second annular ring 221 embedded in the annular groove 217 is integrally provided. On the circumferential side of the handle cover 22, an annular protrusion 222 for pressing against the inner wall of the inner container 21 when the handle cover 22 is installed in place is integrally provided.

[0046] As Figure 3 and Figure 7As shown in the figure, the bottle cap 3 includes an outer cap 31, an inner cap 32 adhesively provided inside the outer cap 31 and having a screwed-in internal thread 321, and a sealing gasket 33 embedded inside the inner cap 32 and pressed against the replacement inner cup 2 during the installation of the bottle cap 3; a plurality of anti-slip strips 322 are circumferentially and arrayed on the circumferential side of the inner cap 32 and abut against the inner wall of the outer cap 31 during the process of being embedded in the outer cap 31. A glue injection groove 323 is recessed downward on the upper surface of the inner cap 32. A glue injection hole 324 communicating with the glue injection groove 323 is provided on the inner cap 32. A partition ring 325 that abuts against the inside of the outer cap 31 after the inner cap 32 is installed is provided in the glue injection groove 323. The glue injection hole 324 is located inside the partition ring 325. A fixed glue layer 326 is formed between the inner cap 32 and the outer cap 31 after the glue injection solidifies.

[0047] Implementation effect: When installing the replacement inner cup 2, first align the two arc-shaped pieces 213 of the replacement inner cup 2 with the two notches 13 of the bottle body 1, and press the replacement inner cup 2 downward into the receiving cavity 11 of the bottle body 1. During this process, the snap-in strips 214 and snap-in protrusions 215 are inserted into the first movable groove 131 from top to bottom, and a plurality of positioning strips 212 abut against the inner wall of the receiving cavity 11. Then rotate the replacement inner cup 2 so that the snap-in strips 214 and snap-in protrusions 215 are inserted into the second sliding groove. During this process, due to the deformation of the arc-shaped piece 213, the snap-in ridge 133 is inserted between the snap-in strip 214 and the snap-in protrusion 215; finally, during the installation process of the replacement inner cup 2, since the contact area between the positioning strip 212, the snap-in piece and the bottle body 1 is small, the friction force received is small. At the same time, during the process of the snap-in ridge 133 being inserted between the snap-in strip 214 and the snap-in protrusion 215, the arc-shaped positioning protrusion 14 needs to pass through the snap-in ridge 133 during the deformation process of the arc-shaped piece 213, and a sound will be made during this process to feedback to the user that the installation is in place. Therefore, it has the effect of improving the smoothness of the installation of the replacement inner cup 2; at the same time, the notch 13 for the arc-shaped piece 213 to move is provided on the screwed-in external thread 12. Compared with the design in the comparative document where the notch 13 is provided above the screwed-in external thread 12, it will not affect the required depth when designing the bottle cap 3, so as to ensure that the height of the bottle cap 3 and the height of the bottle body 1 are kept in a suitable proportion.

[0048] By providing a positioning protrusion 14 at the top of the bottle body 1 and a corresponding positioning groove 216 on the lower surface of the first annular ring 211 of the replaceable inner cup 2, the installation of the replaceable inner cup 2 is further positioned. At the same time, when the fastening strip 214 and the fastening protrusion 215 are in the first movable groove 131, the provision of the positioning protrusion 14 allows a gap to exist between the first annular ring 211 and the upper surface of the bottle body. At this time, the positioning groove is separated from the inner wall of the receiving cavity 11, so as to reduce the frictional force during the removal of the replaceable inner cup 2, which facilitates the removal of the replaceable inner cup 2. After the inner liner 21 of the replaceable inner cup 2 is installed, since the circumference of the inner liner 21 is spaced from the inner wall of the receiving cavity 11 and the bottom of the inner liner 21 is spaced from the bottom of the receiving cavity 11, the space formed therebetween has the effect of heat preservation and heat insulation. The provision of the annular groove 217 of the inner liner 21 and the second annular ring 221 of the handle cover 22 can position the installation of the handle cover 22. The annular protrusion 222 on the circumference of the handle cover 22 abuts against the inner wall of the inner liner 21 when the handle cover 22 is installed in place, so as to slightly fix the installed handle cover 22 through frictional force and prevent the handle cover 22 from falling off directly without external force. During the process of the inner cover 32 being inserted into the outer cover 31, a plurality of circumferentially arrayed anti-slip strips 322 can firmly abut and fix against the inner wall of the outer cover 31, and the frictional resistance during the insertion of the inner cover 32 into the outer cover 31 will not be too large. And by providing the glue injection groove 323 and the glue injection hole 324, after injecting glue, the outer cover 31 and the inner cover 32 can be adhesively fixed, and the provision of the separating ring 325 can prevent the glue from overflowing from the connection gap between the inner cover 32 and the outer cover 31 during the glue injection process.

[0049] Embodiment 2: A replaceable inner cup type cosmetic container, based on Embodiment 1 and cooperating with Figures 8 to 10 As shown, the difference from Embodiment 1 is that: at the bottom of the receiving cavity 11, there is a jacking mechanism for driving the replaceable inner cup 2 to move upward when the fastening strip 214 and the fastening protrusion 215 are in the first movable groove 131; at the bottom of the receiving cavity 11, there is a first installation groove 15, and the jacking mechanism includes a jacking sleeve 41 telescopically arranged in the first installation groove 15 and a driving component 42 for driving the jacking sleeve 41 to move upward to drive the replaceable inner cup 2 to move upward.

[0050] Based on Embodiment 1 and cooperating with Figures 8 to 10As shown in the figure, a regular polygon groove 411 is provided at the top of the ejection sleeve 41, and a regular polygon portion 218 embedded in the regular polygon groove 411 is provided at the bottom of the replacement inner cup 2. The driving assembly 42 includes a mounting plate 421 adhesively provided at the bottom of the first mounting groove 15, a connecting ring 422, and a first compression spring 423 fixedly provided between the connecting rings 422 of the mounting plate 421. The bottom of the ejection sleeve 41 is rotatably connected to the middle of the connecting ring 422. A plurality of second moving grooves 151 extending in the vertically downward direction are provided on the inner wall of the first mounting groove 15. A second fastening groove 152 communicating with the bottom of the second moving groove 151 and extending in the horizontal direction is provided on the inner wall of the first mounting groove 15. A fastening block 412 is provided on the circumferential side of the ejection sleeve 41. During the process of pressing down and rotating and fastening the replacement inner cup 2, the fastening block 412 moves downward along the second moving groove 151 and rotates along the second fastening groove 152 and then fastens.

[0051] Implementation effect: During the process of pressing down and rotating and fastening the replacement inner cup 2, the fastening block 412 moves downward along the second moving groove 151 and rotates along the second fastening groove 152 and then fastens, so that the ejection sleeve 41 can be fastened in the second fastening groove 152 of the first mounting groove 15 for limiting, and no continuous acting force is applied to the bottom of the replacement inner cup 2, so as to avoid deformation of the bottom of the replacement inner cup 2. At this time, the wall thickness of the replacement inner cup 2 can also be thinner during design, avoiding excessive material waste, which conforms to the environmental protection concept; at the same time, when the fastening strip 214 and the fastening protrusion 215 are in the first moving groove 131, the fastening block 412 also rotates into the second moving groove 151. At this time, through the elastic force of the first compression spring 423, the ejection sleeve 41 can be driven to move upward, thereby driving the replacement inner cup 2 to move upward to facilitate the removal of the replacement inner cup 2.

[0052] Embodiment 3: A replaceable inner cup type cosmetic container, based on Embodiment 1, in cooperation with Figures 11 to 13 As shown in the figure, the difference from Embodiment 1 is that: a top ejection mechanism for driving the replacement inner cup 2 to move upward when the fastening strip 214 and the fastening protrusion 215 are in the first moving groove 131 is provided at the bottom of the accommodating cavity 11; a first mounting groove 15 is provided at the bottom of the accommodating cavity 11, and the top ejection mechanism includes an ejection sleeve 41 telescopically provided in the first mounting groove 15 and a driving assembly 42 for driving the ejection sleeve 41 to move upward to drive the replacement inner cup 2 to move upward.

[0053] Based on Embodiment 1, in cooperation with Figures 11 to 13As shown in the figure, the first installation groove 15 is square. A second installation groove 16, which is communicated with the first installation groove 15 and has a "convex" cross-section, is provided at the bottom of the bottle body 1. The driving assembly 42 includes a knob 424 disposed in the second installation groove 16 and having its bottom flush with the bottom surface of the lower part of the bottle body 1, a connecting plate 425 telescopically arranged in the first installation groove 15, a rotating shaft 426 disposed on the knob 424 and passing through the connecting plate 425, a second compression spring 427 disposed at one end of the rotating shaft 426 passing through the connecting plate 425, an anti-detachment end cap 428 disposed at the upper end of the rotating shaft 426 to prevent the second compression spring 427 from falling off, and a linkage 429 disposed between the connecting plate 425 and the knob 424 and driving the connecting plate 425 to move upward against the elastic force of the second compression spring 427 during the rotation of the knob 424. The ejecting sleeve 41 is fixedly arranged on the connecting plate 425 by screws (not shown in the figure), and the connecting plate 425 drives the replacement inner cup 2 to move upward during the upward movement.

[0056] On the basis of Example 1, in cooperation with Figure 14As shown in the figure, a third installation groove 17, which is communicated with the second installation groove 16 and has a "convex" cross-section, is provided at the bottom of the bottle body 1. The driving assembly 42 includes a flexible bladder 4210 embedded in the third installation groove 17 and having a lower surface flush with the lower surface of the bottle body 1, an airbag 4211 provided in the first installation groove 15 and adhered to the ejecting sleeve 41, and an air tube 4212 provided between the airbag 4211 and the flexible bladder 4210. During the process of pressing the flexible bladder 4210, the airbag 4211 is inflated to drive the ejecting sleeve 41 to move upward. When the flexible bladder 4210 is released, the flexible bladder 4210 gradually restores its deformation.

[0057] Implementation effect: When it is necessary to drive the ejecting sleeve 41 to move upward, by pressing the flexible bladder 4210, the airbag 4211 is inflated to drive the ejecting sleeve 41 to move upward. When the flexible bladder 4210 is released, the flexible bladder 4210 will gradually restore its deformation. Moreover, during the installation process of the new replacement inner cup 2, by squeezing the inflated airbag 4211, the gas can also flow back into the flexible bladder 4210, enabling the flexible bladder 4210 to quickly restore its deformation.
