Description

The safe water tap

Technical field

The utility model relates to water tap, relates in particular to a kind of safe water tap.

Background technique

The exposed structure of the many employings of the water tap of small household appliances such as existing drinking machine, water purifier is as Chinese patent application the 98223856.8th disclosed structure for water tap.This class water tap is installed in outside the drinking machine main body, generally comprise body, reposition element and handle, further be formed with water-inlet cavity and water chamber in this body, be provided with the spool that controlled water flow discharges between this water-inlet cavity, the water chamber, time spent not, spool blocking-up water-inlet cavity can not reserve current with water chamber, during use, by carry by or driving handle control valve core movement, water-inlet cavity and water chamber are connected, water can flow out, and after using up, reposition element impels operating grip to reply original state.

This class water tap by carry by or driving handle realize that current discharge, though comparatively convenient in the use, because will cause that current discharge, therefore as long as touch handle, owing to misoperations such as mistake is bumped, bump touch handle current will be discharged, cause the unnecessary wasting of resources; In addition, current are discharged, in the actual life, child's improper use or false touch handle also usually take place make hot water outflow in the drinking machine, cause the accident of scalding because handle very easily is touched.

Therefore, be necessary to provide a kind of water tap safe in utilization to address the above problem.

Summary of the invention

The technical problems to be solved in the utility model is to propose a kind of water tap safe in utilization.

For this reason, the technological scheme that its technical problem that solves the utility model adopts is: a kind of safe water tap, be installed on the equipment such as drinking machine, comprise body, be located at return unit, the operating grip that is connected with described return unit on the described body and be located at described external face shield versatilely.Comprise water intake in the described body, water outlet and control the flow-limiting valve that described water outlet is communicated with or blocks with water intake.Described return unit comprises Returnning spring and connecting rod.Described face shield is provided with first snap-in structure.Described operating grip comprises main part and can be installed in locking device on the described main part, described locking device comprises and can be fixed on the cover plate on the described main part and be installed in lock sheet groups between described main part and the cover plate, described lock sheet groups comprises latch fitting and elastic component, and first snap-in structure on the corresponding described face shield further is provided with second snap-in structure on the described latch fitting.

Wherein, when second snap-in structure of described latch fitting cooperates buckle with first snap-in structure of described face shield under described elastic component resilient force, described operating grip is in the primary importance that is limited to operate, push described latch fitting and make second snap-in structure on it when first snap-in structure of described face shield discharges, described operating grip is in the exercisable second place.

The beneficial effects of the utility model: the utility model increases locking device on operating grip, it cooperates with the corresponding snap-in structure that lock is stated on the face shield, when operating grip is in locking device and cooperates the primary importance of buckle with the face shield corresponding construction, the operation of operating grip is limited, the flow-limiting valve motion of the control body that promptly can not be pressed, water outlet is communicated with water intake, current are discharged, therefore, even false touch this moment operation panel, can not cause that current discharge yet, thereby effectively prevent because the accident that false touch water tap operating grip causes is used safer.
