Description

Technical Field

[0001] This invention relates to the field of water tank technology, specifically to a bagged liquid follow-up connection interface device. Background Technology

[0002] Water dispensers are common household appliances with widespread use. Current water dispensers work by filling a tank with commercially available bottled or bagged purified water, which is then dispensed through a pipe for drinking. Purified water dispensers can be installed with the opening facing downwards or upwards. Downward-facing installation is not only more difficult but also inevitably results in some water loss during installation. Therefore, upward-facing installations are more environmentally friendly.

[0003] However, for water dispensers installed with the opening facing upwards, the suction port of the pipe cannot descend with the drop in the level of purified water, which may result in the suction port being above the water level and thus unable to function. Summary of the Invention

[0004] The purpose of this invention is to solve the problem of empty suction caused by the suction port detaching from the liquid surface when bagged liquid is supplied to the equipment pipeline by the suction principle, and to provide a design scheme for a follow-up connection interface device for bagged liquid.

[0005] To achieve the above objectives, a follow-up connection interface device for bagged liquid is designed, including a water tank for holding bagged liquid, an outlet valve at the top of the bagged liquid, a vertical groove on the side wall of the water tank, a follow-up connection interface and a follow-up module, which are connected and cooperate within the groove and can move up and down along the groove. The follow-up connection interface with an external thread limiting structure is connected and cooperates with the outlet valve on the bagged liquid.

[0006] The present invention also has the following preferred technical solutions:

[0007] 1. The follow-up connection interface also includes a knurled nut, a flexible through-hole sealing plug, a one-way check valve, an external threaded through-hole plug, and the follow-up connection interface body. The through-hole on the knurled nut is aligned with the internal threaded through-hole of the follow-up connection interface body. The external threaded through-hole plug passes through the through-hole of the knurled nut and is screwed into the internal threaded through-hole of the follow-up connection interface body to form a single unit. The one-way check valve is inserted into the external threaded through-hole plug, and the flexible through-hole sealing plug is inserted into the external threaded through-hole plug. The external threaded limiting structure is screwed into the knurled nut to engage with the internal thread.

[0008] 2. The outer ring of the external threaded through-hole plug is larger than the bottom opening of the knurled nut through-hole. After tightening, the knurled nut can rotate freely but cannot disengage from the follow-up connection interface body.

[0009] 3. The follow-up communication interface further comprises a guide structure fixedly formed in one body with the follow-up communication interface body through a pin or a fixing screw, and a guide sliding block on the external thread limiting structure enters the guide structure.

[0010] 4. The rotating knurled nut, since the external thread limiting structure is matched with the inserted knurled nut, and the guide sliding block on the external thread limiting structure enters the guide structure, the knurled nut rotates in the positive direction or the reverse direction, so that the external thread limiting structure moves outward or inward along the guide structure.

[0011] 5. The follow-up module comprises a hole sliding block with left and right shafts, one side of the hole sliding block is used for connecting the follow-up communication interface body, and the other side is used for connecting the through-hole counterweight block.

[0012] 6. The side wall of the water tank provided with a groove is provided with a limiting groove, which is matched with the left and right shafts of the follow-up module, so that the follow-up module can move up and down along the groove, but cannot be turned over. The top of the limiting groove is provided with a notch, so that the left and right shafts of the follow-up module are separated from the limiting groove, cannot be pulled out, and can be turned over.

[0013] 7. The follow-up module further comprises a hollow pipe, the hollow pipe passes through the through-hole counterweight block, one end of the hollow pipe is connected with the follow-up communication interface through a quick plug connector, and the other end of the hollow pipe is connected with the water inlet pipe through a quick plug connector.

[0014] 8. The outer side of the side wall of the water tank is further provided with a pipeline rotation buckle, the pipeline rotation buckle is used for clamping the water inlet pipe, a pipeline rotation buckle fixing screw passes through a pipeline rotation buckle mounting base through hole and is connected with the pipeline rotation buckle; the pipeline rotation buckle can be freely rotated with the pipeline rotation buckle mounting base through hole as the center, and will not be separated from the pipeline rotation buckle mounting base.

[0015] Compared with the prior art, the device pipeline suction port is tightly connected with the bagged liquid outlet, and synchronously descends with the pipeline suction port as the liquid level in the packaged liquid decreases, so that the pipeline suction port is always on the surface of the bagged liquid, and the generation of the adverse working condition of empty suction of the pipeline suction port is solved.

[0058] Rotating the knurled nut, since the external thread limit structure is matched with the threaded hole in the knurled nut, and the guide slider on the external thread limit structure enters the guide structure, rotating the knurled nut in the forward or reverse direction causes the external thread limit structure to move outward or inward along the guide structure.

[0059] Referring toFigures 10-14 The follow-up module comprises a slotted slider with left and right shafts, one side of the slotted slider being used to connect the follow-up type communication interface body and the other side being used to connect the through-hole counterweight. The follow-up module further comprises a hollow tube, the hollow tube passing through the through-hole counterweight, one end of the hollow tube being connected to the follow-up type communication interface through a quick connector, and the other end of the hollow tube being connected to the water inlet pipe through a quick connector.
