Toilet cistern

Abstract

A toilet water tank, which belongs to toilet sanitary ware, includes a tank body, a tank cover, a tank body water inlet, a flushing water outlet, a flushing water control mechanism, and a water level control mechanism, and is characterized in that the water level control mechanism is a valve body water inlet and After the water inlet of the box body is connected, it is suspended and fixed on the top surface of the valve cover inside the upper mouth of the box body to the level of the highest water level. The miniature pressure differential water level automatic control valve is composed of a valve body, a valve cover and a valve core assembly. . When the water level in the water tank is low or there is no water, the valve core assembly is in the position of opening the water outlet of the valve body due to its own weight, and the tap water enters the water tank through the inner cavity of the valve body. The spool assembly moves up and closes the control valve, realizing automatic control of the water level of the water tank. The toilet water tank of this scheme has a simple structure and is convenient to manufacture, install and use, and is a major innovation of the traditional floating ball lever principle toilet water tank.

Description

technical field [0001] The invention belongs to toilet sanitary ware, in particular to a water storage tank of a toilet. Background technique [0002] Traditional toilet water storage tanks are all manufactured using the floating ball lever principle, using the lifting of the floating ball to drive the needle valve mechanism linked with the lever to open and close the water inlet of the tap water to realize automatic control of the water level of the water tank. The water level control mechanism of the water tank with this structure has a large shape and complicated parts and components, which not only occupies more limited space in the water tank, but is not conducive to the installation and opening and closing of the flushing and discharging mechanism, and the floating ball also directly reduces the effective water storage capacity of the water tank. . After improvement, some toilets changed the floating ball into a buoy. Although it does not affect the capacity of the wa...

AI Technical Summary

Problems solved by technology

The water level control mechanism of the water tank with this structure has a large shape and complicated parts and components, which not only occupies more limited space in the water tank, but is not conducive to the installation and opening and closing of the flushing and discharging mechanism, and the floating ball also directly reduces the effective water storage capacity of the water tank.

After improvement, some toilets changed the floating ball into a buoy, although the capacity of the water tank can not be affected, but in order to maintain sufficient buoyancy, the volume of the buoy must be larger than the floating ball, and the lever structure still cannot be less. so still unsatisfactory

Chinese patent ZL200620057017.1 "A kind of internal control water inlet valve for toilet water tank" changes the floating ball (pontoon) into an air pressure cup, uses the air pressure cup and the connecting rod control switch assembly to control the water level of the water tank, not only the structure is more and more complicated, but also It does not overcome the defects of the traditional toilet water tank
