Water-saving-type flush toilet water inflowing and draining opening and closing device controlled by hydraulic transmission

Abstract

The invention discloses a water-saving-type flush toilet water inflowing and draining opening and closing device, and particularly relates to a water-saving-type flush toilet water inflowing and draining opening and closing device controlled by hydraulic transmission. A hydraulic transmission control device is connected with a water inflowing control device and a sewage discharging opening and closing device through a valve body three-way pipe. The sewage discharging opening and closing device comprises a sewage discharging opening and closing valve body. The upper end of the sewage discharging opening and closing valve body is fixedly connected with a supporting plate through a screw. A sewage discharging hydraulic cylinder body is hinged to a support at the right end of the supporting plate. An opening and closing piston is installed inside the sewage discharging hydraulic cylinder body. The upper end of the opening and closing piston is hinged to a rocker arm. The rocker arm is hinged to the right side of the supporting plate. The lower portion of the rocker arm is provided with a sealing rubber plate. The sealing rubber plate is tightly attached to the right side of a sewage inflowing sleeve which is installed on the left side of the sewage discharging opening and closing valve body. A tension spring is arranged between the rocker arm and the screw. The upper end of the sewage discharging hydraulic cylinder body is connected with a locking cover. A liquid inlet of the sewage discharging hydraulic cylinder body is communicated with the lower end of the valve body three-way pipe through a connecting hose. According to the water-saving-type flush toilet water inflowing and draining opening and closing device controlled by hydraulic transmission, the hydraulic transmission and the lever principle are adopted at the same time to control water draining and water inflowing, the structure is simple, the design is reasonable, and the water-saving-type flush toilet water inflowing and draining opening and closing device is practical and reliable.

Description

technical field [0001] The invention discloses a water-saving type flush toilet inlet and drain gate, in particular to a water-saving type flush toilet inlet and drain gate controlled by hydraulic transmission. Background technique [0002] At present, known flush toilet inlet and drain gates mainly contain two kinds of mechanical type and induction type. The mechanical type is generally composed of a drain button or knob, a water inlet valve, a float, etc., wherein the float or knob is connected to the water inlet valve switch through a connecting rod. After flushing, the float or knob falls to close the water inlet valve, and the water tank enters When the water in the water tank reaches the set height, the water inlet mechanism will automatically close and stop the water intake. This kind of toilet will flow out most of the water in the water tank every time, which is not conducive to fundamentally saving water resources. The structure of the induction toilet automatic f...

Problems solved by technology

The mechanical type is generally composed of a drain button or knob, a water inlet valve, a float, etc., wherein the float or knob is connected to the water inlet valve switch through a connecting rod. After flushing, the float or knob falls to close the water inlet valve, and the water tank enters , the water in the water tank reaches the set height and the water inlet mechanism automatically closes to stop the water intake. This kind of toilet will flow out most of the water in the water tank every time, which is not conducive to fundamentally saving water resources.

The structure of the induction toilet automatic flushing device generally includes components such as sensors, electromagnets, two-position three-way valves, and sealing rings. The purpose of opening or closing the flushing pipe is achieved through infrared or pressure sensing principles. The main problems are insufficient durability, Cannot be used during power outage

The hydraulic transmission control water inlet and sewage discharge water-saving flushing toilet hydraulic inlet and drainage gate designed by the present invention includes a control hydraulic cylinder, a water inlet hydraulic control valve, a sewage discharge hydraulic cylinder, a sewage discharge opening and closing valve and a connecting soft The main purpose is to overcome the shortcomings of the existing mechanical water valves such as poor sealing, large water consumption, and the complex structure of the induction water valve, which has potential safety hazards and waste of electric energy.
