CN2732862Y - Water-saving flushing device for closet - Google Patents

Abstract

The utility model relates to a water-saving flushing device for closet, composed of a ball valve A which is installed on the ingress of a water supply pipe inside a water tank, a siphon valve, a siphon and a one-way valve which are installed on outlet of a flushing pipe. The top of the siphon is higher than the upper limit of the water level of the water tank. The utility model is characterized in that one end of the siphon is communicated with the upper chamber of the siphon valve which is divided by a diaphragm and the egress of the siphon valve is communicated with the flushing pipe; the other end of the siphon is respectively communicated with the flushing pipe and an air-operated switch arranged outside the water tank through a ball valve B; when the floating ball of the ball valve B is above the upper limit of the water level of the water tank, the ball valve B is open, when the floating ball of the ball valve B is under the upper limit of the water level, the ball valve B is closed. The part that extends out of water tank of the connecting tubes of the siphon and the air-operated valve is 30 mm or more than 30 mm higher than the upper limit of the water level of the water tank. The utility model has the advantages that only if the water tank is full of water, the water tank can control flushing by the air-operated switch. Thereby, cleaning effect can be ensured and water can be saved.

Description

The water saving type urinal flusher

Technical field: the utility model relates to a kind of public health infrastructure urinal flusher, particularly water saving type urinal flusher.

Background technology: the slot type urinal is very general in the communal toilet, and it cleans the high level cisterns of flushing automatically that adopt more, utilizes the power flushing toilet bowl of water drop.The defective of this water tank is whether no matter the human lavatory arranged, and whether urinal needs to clean, and therefore its flushing that just discharges water automatically when always reaching upper limit water level by cistern water level causes the water waste seriously; And existing electronic, surge or the slot type urinal flusher of pneumatic control also still has weak point, no matter promptly the aqueous phase water yield how much, as long as press automatically controlled or hydraulic control or gas control switch, the water tank flushing that just discharges water, work as the water tank middle water level like this and also do not reach upper limit water level, during water shortage, if the flushing that discharges water does not only reach developing result but also wasted water.

Summary of the invention: the purpose of this utility model is to provide a kind of water saving type urinal automatic flushing device, the employing hydraulically controlled pneumatic combines, and when having only water tank to hold full water, could control the flushing that discharges water, reach like this and not only guarantee developing result but also conserve water, overcome the above-mentioned defective of prior art.

Technical solution of the present utility model is a kind of water saving type urinal flusher, mainly float valve is installed by feed pipe import department in the water tank, the cleaning hose exit is installed siphon valve and syphon and one way valve and is formed, the syphon top is higher than the water tank middle water level upper limit, the epicoele of being separated by diaphragm in syphon one end and the siphon valve is communicated with, and the outlet of siphon valve is communicated with cleaning hose; The syphon other end is communicated with cleaning hose respectively and is communicated with jettron outside the water tank through float valve B; When the ball float of float valve B was in the water tank upper limit water level, float valve B was in opening, and when ball float was lower than upper limit water level, float valve B was in closed condition.The connecting tube of syphon and pneumatic operated valve stretches out that the outer part position of water tank is higher than water tank upper limit water level 30mm or more than the 30mm.

Description of drawings:

Fig. 1 is the utility model water saving type urinal flusher structure chart

The specific embodiment:

The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:

A kind of water saving type urinal flusher, its structure is referring to accompanying drawing 1, mainly float valve A3 is installed by feed pipe 2 import departments in the water tank 1, siphon valve 4 is installed in cleaning hose 10 exits and syphon 5 is formed, syphon 5 tops are higher than upper limit water level H in the water tank, the epicoele of being separated by diaphragm 11 in syphon 5 one ends and the siphon valve 4 12 is communicated with, and the outlet of siphon valve 4 is communicated with cleaning hose 10; Syphon 5 other ends are equipped with one way valve 6, are communicated with cleaning hose 10 respectively and are communicated with jettron 9 outside the water tank 1 through float valve B7; When the ball float of float valve B7 was in the water tank upper limit water level H, float valve B7 was in opening, and when ball float was lower than upper limit water level H, float valve B7 closed, and jettron 9 is loaded on the wall 13.

When retaining reached upper limit water level H in the water tank, float valve A closed, and stops to cistern water supply, and when being lower than upper limit water level H, float valve A opens, to cistern water supply.

The opposite states that under buoyancy function, makes float valve B and A open and close of float valve B and float valve A.

Syphon 5 and the connecting tube 8 of jettron 9 stretch out that the outer part position of tank top is higher than water tank upper limit water level H30mm or more than the 30mm.To prevent the reverse inflow jettron of water.

The utility model operating principle is: by the water inlet water storage of float valve A control wc flushing cistern, when liquid level was lower than upper limit water level H, float valve A opened, and the feed pipe feed tank supplies water, and full water is supreme restricts water supply during H when water tank holds, and float valve A closes, and stops to cistern water supply; The flushing of being controlled water tank by float valve B and jettron jointly discharges water, when the water tank middle water level is lower than upper limit water level H, float valve B closes, even this moment operation jettron is in the unlatching gear, can not control the water tank flushing that discharges water, have only when water tank holds full water, the operation jettron is opened, and could control the water tank flushing that discharges water, thereby guarantee that each flushing water has enough water yields that urinal is rinsed well, reach developing result, the while is also effectively utilized flushing water and can not waste.

The utility model advantage is to only have when water tank holds full water to control the flushing that discharges water by jettron, thereby Not only guaranteed developing result but also can using water wisely.
