Description

Water tap of water bag Technical Field The utility model relates to the technical field of water heads, in particular to a water head of a water bag. Background The existing water-pumping head of the water bag is usually controlled to be on-off by adopting a straight-through pipe body matched with an independent valve core or a plug cap, and the use flow is that the water-pumping head of the water bag is firstly opened, then a female head of a water supply device (such as a water dispenser or a booster pump) is quickly connected with a water inlet interface of the water-pumping head and kept sealed, then the water supply device is started to fill water into the soft water bag, and after the water-pumping head is filled, an operator needs to firstly release the plug connection or the threaded connection of the female head and the water-pumping head, and then the valve core on the water-pumping head is rotated or pushed and pulled to close water flow. The device is widely used in the scenes of water injection of household hot water bags and the like, and has simple structure and low manufacturing cost. However, in soft or hot water filled water bags, the above-mentioned sequence of first removing the female head and then closing the valve is prone to deformation and pumping of the hose due to release of pressure in the water bag, water leakage and even splashing, hot water leakage may cause scalding risks when high temperature liquid is conveyed, in addition, operation time and misoperation probability are increased, once the valve core is misaligned or the sealing surface is worn, problems of scalding and wasting water resources due to water leakage are also caused, and improvement is needed. Disclosure of utility model The utility model aims to provide a water pumping head of a water bag so as to solve the problems in the background art. The water pump head comprises a connecting seat, a water injection pipe, a water inlet hole and a plugging component, wherein the connecting seat is used for being connected with the water bag, the water injection pipe is vertically arranged above the connecting seat, a water permeable hole is formed in the joint part of the water injection pipe and the connecting seat, the water inlet hole comprises a first water inlet section and a second water inlet section, the first water inlet section and the second water inlet section are both arranged on the inner side of the water injection pipe, a sealing cover is further arranged at the first water inlet section, the second water inlet section is communicated with the water permeable hole, and the plugging component can rotate around the axis of the water injection pipe and axially displace to selectively enable the water permeable hole to be opened and closed. In one possible embodiment, the first water inlet section and the second water inlet section form a step-shaped transition in the axial direction, and the step surface forms an abutting end. In a feasible implementation mode, the plugging assembly comprises a spiral guide groove, a rotary cap and a plug body, wherein the two spiral guide grooves are respectively formed in the outer side of the outer wall of the connecting seat, two sliding blocks are arranged on the inner side of the rotary cap and movably arranged at the two spiral guide grooves through the two sliding blocks, one end of the plug body is fixedly arranged on the inner side of the rotary cap, the outer edge part of the plug body is tightly attached to the second water inlet section, and the other end of the plug body can be selectively abutted to the abutting end.
