Problems solved by technology

However, the greater the opening distance of the opening device, the more inconvenient to operate, so in the prior art, in order to reduce the opening distance of the operation without affecting the opening height of the drain valve's drain parts, an enlarged stroke mechanism is usually used to open the drain valve's drain parts , but this will cause the opening force of the opening device to increase

Embodiment 1

[0026] See figure 1 , figure 2 As shown, the opening device of the present invention, which is controlled by hydraulic pressure, includes a starting body 1 with a hollow inner cavity, a piston 2, an elastic member 3 and a pressure relief mechanism; the piston 2 is sealed and mounted on the starting body 1 so that it can move up and down Inside, and between the top of the piston 2 and the starting body 1, a water storage chamber 11 for storing water to push the piston 2 down is formed. The water storage chamber 11 has a water inlet 511 for connecting to a pressure water source. The water storage cavity 11 uses a pressure relief mechanism to realize drainage and pressure relief; the piston 2 is reset by the elastic member 3, so as to move up after the water storage cavity 11 is drained and pressure relieved to drive the drainage mechanism to discharge water.

[0027] As a preference, the bottom end of the above-mentioned piston 2 cooperates with a locking mechanism, and the pi...

Embodiment 2

[0040] An opening device for hydraulically controlled lifting of the present invention, please refer to Figure 5 , Figure 6 As shown, the difference between it and the first embodiment above is that its locking mechanism includes a stroke control block 7 installed on the drainage part of the drain valve (that is, the valve stem 63 ) and a valve stem 63 formed on the inner surface of the annular inner wall. A tapered hole 71 with a wide top and a narrow bottom, the stroke control block 7 includes an outer wall 72, and the tapered hole 71 is coaxially arranged in the outer wall 72; the locking mechanism also includes eight rings arranged at the bottom of the piston 2 and can The slices 22 that elastically swing in the radial direction, the ends of the eight slices 22 are hemispherical, and their maximum outer diameter is greater than the minimum inner diameter of the tapered hole 71, then the slices at the bottom end of the piston 2 and the valve stem 63 The ring-shaped inner...

Abstract

The invention discloses an opening device controlling lifting with water pressure and a flushing device. The opening device comprises a starting body with an inner cavity, a piston, an elastic part and a pressure relief mechanism. The piston can be sealed inside the inner cavity of the starting body in a vertical movement mode. A water storage cavity is formed between the top end of the piston and the starting body and used for storing water to push the piston to move downwards, the water storage cavity is provided with at least one water inlet connected with a pressure water source, and the pressure relief mechanism is adopted for the water storage cavity to achieve drainage and pressure relief. The piston resets through the elastic part so as to move upwards to drive a drainage mechanism to drain the water after the water storage cavity drains the water and relieves pressure. The structure is adopted for controlling the drainage mechanism to drain the water, and therefore the opening device has the advantages of being small in opening force and opening distance, capable of being controlled at a long distance, good in using touch feeling and the like.

Description

technical field [0001] The invention relates to an opening device and a flushing device, in particular to an opening device and a flushing device which are lifted by water pressure control. Background technique [0002] At present, in the flushing device of the prior art, after the drain valve is opened, it should be able to discharge a preset amount of water and be automatically closed. In the traditional flushing device, the opening force of the opening device will increase with the increase of the working water level of the water tank (the higher the working water level is, the better the flushing effect of the toilet will be), and the opening height of the drain part of the drain valve is the same as the opening height of the opening device. The opening distance is related: the greater the opening distance of the opening device, the higher the opening height of the drainage part of the drain valve, and the higher the opening height of the drainage part of the drain valve...
