Abstract

The utility model relates to a water-saving siphon flushing cistern for a toilet bowl, comprising a cistern body, a water inlet valve, a flushing tube, a connecting rod, a floating ball, a handle, a cam and a tension spring. The utility model is characterized in that the connecting rod is an angle type connecting rod whose included angle is smaller than 90 DEG, the flushing tube is an inverted U-shaped tube, and the distance from the cam center to the connecting rod is smaller than the maximum eccentricity of the cam. The utility model has the advantages of tight close of the inlet valve, no water leakage, fast water inflow, large quantity of flushed water, water saving and reliable operation.

Description

Water-saving siphon flushing cistern for toilet closet

The utility model relates to a kind of washroom nightstool cistern, and it belongs to sanitary equipment.

In the hotel, the bath control of the cistern of the washroom of restaurant, office premises, apartment, dwelling house, nightstool, has plenty of the ball float of employing overflow-type, it is automatically controlled to have plenty of employing, have plenty of the employing infrared control, through facts have proved, their water-saving performance is all not ideal enough, the ball float overflow-type, often by poorly sealed, or impurity such as silt particle in the water, drainage caused; Automatically controlled often by malfunctioning or power failure of element etc., cause waste; Infrared control by improper use etc., causes waste often, and people try hard to design the water-saving nightstool cistern of a kind of service-strong for this reason.

The purpose of this utility model is to provide a kind of water-saving washroom nightstool syphon flushing water water tank, and this water tank has the characteristics reliable, that water-saving performance is good of using.

Structure of the present utility model is such: in the casing of bucket, (this valve has obtained patent to the water intaking valve of a leverage formula of the one side device switch of its bottom: ZL.92230656.7), connect an angle less than 90 ° angie type connecting rod at the lever bracket of valve, the end of connecting rod connects ball float, valve body stretches out outer part at the bottom of the case, link to each other with the ambient pressure water pipe, opposite side is provided with " U " type pipe at the bottom of case, and this pipe is jet water spout, in the casing front, be positioned at a distance, angie type connecting rod left side, a handle is housed, and the cam that can clockwise rotate 90 ° in this handle and the casing links to each other, when cam clockwise rotates 90 °, maximum flange roof pressure angie type connecting rod, force its pendulum position, and then can open spool, ambient pressure water enters water tank, be provided with an extension spring in the outside of cam, it can make cam reset.

Architectural feature of the present utility model is: one, connect an angle less than 90 ° angie type connecting rod on the switch thill bridge of water intaking valve, the end of this connecting rod connects ball float; Two, jet water spout adopts an inversion " U " type pipe, and its water inlet pipe mouth and case bottom surface keep certain distance; Three, cam center arrives the maximum eccentricity of the distance of connecting rod less than cam.

Structural representation when Fig. 1 is the utility model non-action status; Fig. 2 is the utility model place status architecture schematic diagram that advances to wash by water.In Fig. 2, wherein 1 is casing, and 2 is water intaking valve, and 3 is the angie type connecting rod, and 4 is ball float, and 5 is jet water spout, and 6 is handle, and 7 is cam, and 8 are extension spring.

The utility model realizes that into water-rinsing process is, handle is clockwise rotated 90 °, cam is driven also rotates 90 °, at this moment the highest outer rim roof pressure of cam angie type connecting rod makes it the pendulum position, and spool will be raised, ambient pressure water begins to enter water tank, when water level in the case reached a little higher than jet water spout top, gas emptying in the jet water spout, siphon were flowed and are begun to realize bath, release handle, cam resets, and spool moves down and bars up the inlet opening, stops into water, and jet water spout is still in bath, when water level was lower than the water inlet pipe mouth of jet water spout in case, bath also stopped, and this moment, each parts of water tank were situation shown in Figure 1.

The utlity model has fast into water, amount of flush water is big, water intaking valve is closed tightly, does not produce leakage, the service-strong characteristics.

Claims

1, a kind of by casing, water intaking valve, jet water spout, connecting rod, ball float, and the water-saving washroom nightstool syphon flushing water water tank that constitutes of handle, cam, extension spring, it is characterized in that:

A, open lever bracket at the spool of water intaking valve and connect an angle less than 90 ° angie type connecting rod, the end of connecting rod connects ball float,

B, jet water spout are to be made of an inversion " U " type pipe, and its water inlet pipe mouth and water tank bottom surface keep certain distance,

The distance of the center of c, cam and angie type connecting rod is less than the maximum eccentricity of cam.
