Description

Technical Field

[0001] This invention relates to a structure for mounting a liquid container; more particularly to a liquid container connection device. Background Technology

[0002] Existing liquid supply devices involve inverting a bottle containing liquid onto the device to allow the liquid to flow into the device by gravity, or connecting the bottle body to the cap by screwing a cap on the bottle body and then using a pump to draw the liquid from the bottle body into the device for supply.

[0003] The existing methods described above require stability and prevent shaking when the bottle / canister is inverted during liquid supply to avoid leakage. Furthermore, this design is unsuitable for situations where the bottle / canister moves with the device, or, for example, the cap-attached design described above is cumbersome and time-consuming. All these drawbacks necessitate a design that allows for quick connection between the device and the bottle / canister, facilitating the flow of liquid from the bottle / canister into the liquid supply device. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a connection device for a liquid container that can quickly connect the sleeve of a liquid pipeline to the liquid container, and when the liquid container is connected to the sleeve, the liquid inside will not leak even if it is tilted.

[0005] To achieve the above objectives, the present invention provides a liquid container connection device, comprising a container tank, a liquid container, and a snap-fit ​​structure, wherein the liquid container is placed in the container tank and has a straw at its top. The snap fastening structure includes a connecting seat, a snap fastening element, a lifting seat, two swing arms, and a sleeve. The connecting seat is attached to the top side of the container groove. The connecting seat has two side plates on its left and right sides. The snap fastening element has two side arms on its left and right sides. The rear ends of the two side arms are pivotally connected to the front sides of the two side plates. The two side arms extend forward from the connecting seat, and a snap fastening plate is connected between the front ends of the two side arms. The lifting seat is disposed between the two side plates and has a bottom frame. The lifting seat moves within the connecting seat in the vertical and horizontal directions and in the front and back directions. Two extension arms extend forward from the left and right sides of the bottom frame. The front ends of the two extension arms are pivotally connected to the front sides of the two side arms. The front ends of the two swing arms are pivotally connected to the left and right sides of the bottom frame, and the rear ends of the two swing arms are pivotally connected to the rear sides of the two side plates. The sleeve is attached to the bottom frame and fits onto the straw.

[0006] The advantage of this invention is that by pressing the snap-fit ​​element downwards, the lifting seat and the sleeve descend, allowing the sleeve to engage with the straw of the liquid container. Even if the liquid container connection device is tilted, the liquid inside the container will not leak out. Furthermore, when the liquid container needs to be replaced, simply flipping the snap-fit ​​element upwards raises the lifting seat and the sleeve, releasing the liquid container for the user to remove and replace. This provides a quick and easy way to connect or disconnect the sleeve used to connect to the liquid pipeline from the liquid container. Attached Figure Description

[0072] The container trough 10 can be installed on the structure of certain devices. For example, in this preferred embodiment, the container trough 10 is installed in front of the bottom shell A1 of a mineral water generator A. The container trough 10 has two ends, a top and a bottom, and the interior of the container trough 10 has a receiving space 12, in which the liquid container 20 can be placed.

[0073] Please refer to Figure 2 and Figures 6 to 8As shown, the liquid container 20 is placed in the accommodating space 12 of the container tank 10. The bottom of the liquid container 20 abuts against the bottom end of the container tank 10. The top of the liquid container 20 has a straw 243. The straw 243 is a vertically arranged tube that communicates with the interior of the liquid container 20. The straw 243 can be a vertical plastic tube or a silicone tube that is elastic, can be bent under force, and can return to its original position after release.

[0074] The snap fastening structure 30 includes a connecting seat 32, a snap fastening element 34, a lifting seat 36, two swing arms 38, and a sleeve 31. The connecting seat 32 is connected to the container groove 10 and located on the top side of the accommodating space 12. The connecting seat 32 has two side plates 321 on its left and right sides. Each of the two side plates 321 has a front axle hole 3211 and a rear axle hole 3212 on its front and rear sides. The snap fastening element 34 has two side arms 341 on its left and right sides. Each of the two side arms 341 has a front axle rod 3411 at its rear end. Each front axle rod 3411 pivotally passes through the front axle hole 3211, thereby pivotally connecting the rear end of the two side arms 341 to the front side of the two side plates 321. The two side arms 341 extend forward from the connecting seat 32. Each of the two side arms 341 has a front pivot hole 3412 on its front side, and a snap fastening plate 342 is connected between the front ends of the two side arms 341.

[0075] The lifting seat 36 is disposed between the two side plates 321 of the connecting seat 32 and located directly above the liquid container 20. The lifting seat 36 is restricted to move up and down or forward and backward within the connecting seat 32. The lifting seat 36 has a base frame 361, with two extension arms 3612 extending forward from the left and right sides of the front end of the base frame 361. Each of the two extension arms 3612 has a front pivot rod 3613 at its front end, which pivots through the front pivot hole 3412, thereby pivoting the front end of the two extension arms 3612 to the front side of the two side arms 341. The left and right sides of the base frame 361 have two rear pivot rods 3614, and the front end of each of the two swing arms 38 has a rear pivot hole 381 through which the rear pivot rods 3614 of the base frame 361 pivot. Each rear pivot hole 381 is used to pivotally connect the front end of the two swing arms 38 to the left and right sides of the bottom frame 361. The rear end of each of the two swing arms 38 has an inner shaft hole 382, ​​which is directly opposite to the two rear shaft holes 3212. Each swing arm 383 is provided with a rear shaft rod 383 that pivotally passes through the rear shaft hole 3212 and the inner shaft hole 382, ​​thereby pivotally connecting the rear end of the two swing arms 38 to the rear side of the two side plates 321, so that the two side plates 321, the two side arms 341 of the snap fastener 34, the lifting seat 36 and the two swing arms 38 form a four-bar linkage structure.

[0076] The sleeve 31 is attached to the bottom frame 361, and the bottom of the sleeve 31 is detachably fitted onto the straw 243 at the top of the liquid container 20. When the container tank 10 is located on the bottom shell A1 of the mineral water generator A, the top of the sleeve 31 is used to connect to a connecting pipe 33, which connects to the pipeline inside the mineral water generator A, supplying the liquid, such as mineral water preparation, in the liquid container 20 to the pipeline inside the mineral water generator A. Alternatively, in other preferred embodiments, the liquid is injected into the liquid container 20 from the liquid supply source inside the bottom shell A1 through the connecting pipe 33 and the sleeve 31.

[0077] When it is necessary to use the liquid container connecting device 100 of the present invention to replace the liquid container 20 in the container tank 10, please refer to... Figure 6 and Figures 9A to 9B As shown. The user pulls the clamping plate 342 of the clamping element 34 upwards by hand, causing the front side of the clamping element 34 to rotate upwards. This rotation of the clamping element 34 causes the lifting seat 36 and the sleeve 31 to rise, disengaging the sleeve 31 from the position where it is fitted onto the straw 243 of the liquid container 20, allowing the liquid container 20 to be removed from the container slot 10. Next, the replaced liquid container 20 is placed into the container slot 10, and the clamping plate 342 of the clamping element 34 is pressed downwards, causing the clamping element 34 to rotate back to its original position. This drives the lifting seat 36 and the sleeve 31 to descend, allowing the sleeve 31 to re-fit onto the straw 243 of the liquid container 20, quickly completing the connection between the liquid container 20 and the sleeve 31.

[0078] Further explanation of the structure of the liquid container connecting device 100 of the present invention. Please refer to... Figure 2 and Figures 6 to 9A As shown, the top of the container tank 10 has a connecting part 14, the front of the connecting part 14 has a recess 141, the bottom of the connecting part 14 has an opening 142, the opening 142 is through which a pipe seat 16 passes, the pipe seat 16 has a pipe hole 161, the lifting seat 36 is located directly below the pipe seat 16, and the connecting pipe 33 connected to the top of the sleeve 31 passes upward through the pipe hole 161 and enters the bottom shell A1 to connect with the pipeline inside the mineral water generator A.

[0079] The front side of the connecting seat 32 has a panel frame 322. The upper half of the panel frame 322 is fixed to the recess 141 in front of the assembly part 14. The lower half of the panel frame 322 extends downward from the recess 141. The middle of the lower half of the panel frame 322 has a through-hole 3221. The front edge of the two side plates 321 is connected to the left and right side edges of the lower half of the panel frame 322. The two side arms 341 of the snap fastener 34 pass through the left and right sides of the through-hole 3221. The middle of the snap fastener 34 has a recess 343. The bottom frame 361 extends forward with an elastic arm 3615. The middle of the elastic arm 3615 has a bent elastic structure 3616. The front end of the elastic arm 3615 has a protrusion 3617. The protrusion 3617 is engaged and positioned in the recess 343 of the snap fastener 34.

[0080] The bottom end of the sleeve 31 forms a funnel-shaped opening 311, through which the straw 243 is guided to enter, and the sleeve 31 is fitted onto the top of the straw 243. The sleeve 31 is floatingly connected to the bottom frame 361 in a manner that absorbs the deviation between the sleeve 31 and the bottom frame 361 in the front-to-back direction. In this preferred embodiment, a limiting hole 3611 is provided in the middle of the bottom frame 361. The sleeve 31 is an elastic and deformable plastic tube with a neck 3121 formed around it. The width of the neck 3121 is narrower than the width of its top edge and bottom edge. The sleeve 31 is inserted into the limiting hole 3611 from top to bottom, so that the neck 3121 passes through the limiting hole 3611 and is fixed in a fixed position. The width of the top edge and bottom edge of the neck 3121 is greater than the width of the limiting hole 3611, and the width of the neck 3121 is less than the width of the limiting hole 3121. In this way, the sleeve 31 can move back and forth relative to the bottom frame 361 within the limiting hole 3611. A guide frame 313 is attached around the sleeve 31. The guide frame 313 has two guide rods 3131 on its left and right sides. The two guide rods 3131 are rods that extend in the vertical direction. The two guide rods 3131 are slidably inserted into the left and right sides of the pipe hole 161, so that the guide frame 313 can slide in the vertical direction under the guidance of the pipe wall of the pipe hole 161.

[0081] The aforementioned sleeve 31, through the guide bracket 313, passes through the pipe hole 161 and can be guided by the pipe wall of the pipe hole 161 to move up and down in the vertical direction. This restricts the movement of the lifting seat 36, which is fitted around the neck 312 of the sleeve 31 through the limiting hole 3611, to vertical movement and forward / backward movement. Please refer to... Figures 8 to 9AAs shown, a micro switch 35 is provided behind the panel frame 322. The position of the micro switch 35 forms a protrusion 3618 on the front side of the bottom frame 361. During the raising or lowering of the lifting seat 36, the protrusion 3618 will trigger the micro switch 35. The state of the micro switch 35 being triggered can detect whether the lifting seat 36 is in a high or low position. If the lifting seat 36 is in a low position, it can be known that the snap fastener 30 is connected to the liquid container 20. If the lifting seat 36 is in a high position, it can be known that the snap fastener 30 is in a state of releasing the liquid container 20.

[0082] The liquid container 20 includes a bottle body 22 and a straw element 24. The bottle body 22 has a bottle body 221 and a bottleneck 222 connected to the upper end of the bottle body 221. The straw element 24 has a stopper 241. The inner side of the stopper 241 has a groove 242. The top edge of the outer peripheral surface of the stopper 241 has a flange 2411. The stopper 241 is embedded in the bottleneck 222 and positioned by the flange 2411 abutting against the top edge of the bottleneck 222. The straw 243 is attached to the middle of the bottom of the groove 242. The straw 243 is at least partially located in the groove 242 and its bottom end communicates with the inside of the bottle body 22. In this preferred embodiment, the straw 243 is inserted into the middle of the bottom of the groove 242. The upper half of the straw 243 is located within the groove 242, and its tip extends to align with the tip of the stopper 241. The lower half of the straw 243 extends into the bottle body 221 of the bottle 22. When the sleeve 31 is fitted onto the straw 243, the bottom side of the sleeve 31 enters the groove 242. Since the straw element 24 of the liquid container 20 can be separated from the bottle body 22, when the liquid container connecting device 100 of the present invention replaces the liquid container 20, the straw element 24 can be reused in different bottle bodies 22. Only the different bottle bodies 22 need to be replaced when replacing the liquid container 20, thus saving the required straw element 24.
