Step type deboost pressurized toilet flushing device

Abstract

The invention relates to a step type deboost pressurized toilet flushing device, including: a frame, one side is provided with water inlet pipe and opening at the bottom; a water storage pressurized container, in sealing connection on the frame, wherein, the frame includes a water inlet and outlet part, connected to the water inlet pipe and having openings on the bottom, and the water storage pressurized container in sealing connection at the upper part of the water inlet and outlet part, and is communicated to the water inlet; a valve part located in the water storage pressurized container, and isolated with the internal space of the water storage pressurized container, wherein, a draining valve plate that can pivot to realize start and stop is provided on the valve part; and a wedge column, slidably provided in the frame, wherein, the draining valve plate is closed when the wedge column leans on the draining valve plate, and the draining valve plate is opened uner external hydraulic function when the wedge column is divorced from the draining valve plate. The flushing device uses a side direction door-open type water drainage valve structure, wehrien, the door can be easily opened under water pressure with outing overcoming gravity force and water pressure to pull the valve cover.

Description

technical field [0001] The invention relates to a toilet flushing device, more specifically, to a step-by-step return pressurized toilet flushing device. Background technique [0002] In the existing pressurized toilet flushing device, a valve cover is used to close the drain port. Such as figure 1 As shown, when the user needs to use the toilet flushing device, he will press down the drain switch 11 on the pressurized water container 1, and when the switch extension shaft 111 is pulled up, the control in the pressurized water container 1 will be linked. Rope 12, the control rope 12 pulls the valve cover 13, water will flow into the toilet from the drain port 14, the valve cover 13 will return to its original position due to gravity, block the drain port, and the newly injected water will continue to flow into the water storage pressurized container , waiting for the next use. [0003] The above-mentioned structure has the following disadvantages: this toilet flushing dev...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned structure has the following disadvantages: this toilet flushing device uses the valve cover 13 to close the drain 14, and before the water retaining plate 13 is pulled, the water storage pressurized container 1 has stored more water, which will impose a relatively high pressure on the valve cover 13. High water pressure, when pulling the valve cover 13, not only the gravity of the valve cover 13, but also the water pressure must be overcome, so the user needs to apply a large force to make the valve cover 13 open

This makes the process of opening the valve cover 13 relatively slow, weakening the speed of flushing

In addition, this toilet flushing device does not realize mechanical step-by-step variable water inlet and discharge in the water storage pressurized container 1
