Abstract

The utility model discloses the construction of a water inlet part of a flushing device for a public toilet. The utility model comprises a water tank, a water inlet pipe which is arranged above the water tank, and a floating ball which is arranged in the water tank. The floating ball rises up and falls down following to the water level in the water tank to simultaneously drive a lever which is fixed above the floating ball to support and rotate through a fulcrum pin. The other end of the lever is linked with a valve plate which is extended into an inner cavity of the water inlet pipe to move from top to bottom through a notch which is arranged on the water inlet pipe. A bent rod is arranged below a proper position of the lever, and the lower end of the bent rod is connected with an iron wire. When a pedal is trodden by feet downwards, the upper end of the bent rod is rotated. Because the utility model uses the feet to tread the pedal to cause the lever to be linked, the valve plate of the inner cavity of the water inlet pipe is driven to move from top to bottom, and therefore, a water inlet passage is opened, and water flows into the water tank. Simultaneously, the floating ball rises under the action of buoyancy, the valve plate is linked to fall down, and a water inlet is blocked. The utility model has the advantages of manual control of the water inlet of the water tank, simple structure, convenient and reliable operation, and water resources saving.

Description

A kind of water feed apparatus

Affiliated technology territory

The utility model relates to the flusher that communal bathroom is used, and relates in particular to the structure of its water inlet portion.

Background technology

At present, China has the structure of the flusher that the part public lavatory uses to be: establish a water tank aloft, the water halter of water tank upper end is turned down in advance, with the method control inflow, through the regular hour, when the water level in the water tank arrives set height, just draining flushing automatically, the shortcoming of this flusher is, when the public lavatory frequency of utilization very low or night nobody the time, the ground water inlet because the water halter does not stop to have a rest, water tank still repeats draining, and is very big to water resource waste.

Summary of the invention

The utility model is in order to overcome the deficiencies in the prior art, a kind of water feed apparatus to be provided, and this device is the water inlet of Artificial Control water tank as required.

The technical solution of the utility model is: the utility model comprises water tank, the water inlet pipe of water tank top, the ball float in the water tank, described ball float is with the rising of water tank middle water level, when descending, the lever that its top is fixed in drive supports rotation with fulcrum pin, valve plate of other end interlock of lever, valve plate puts in the water inlet pipe inner chamber by the notch of opening on the water inlet pipe and moves up and down, below the appropriate location of lever, be provided with knee, connect an iron wire in the lower end of knee, by foot pedal when downward, the upper end spinning movement of knee.

The utility model is because the pedal that tramps with one's feet makes the lever interlock, and the valve plate that drives the water inlet pipe inner chamber moves upward, and makes water tank water intake thereby open intake tunnel, and simultaneously, ball float is risen by buoyancy function just, and the interlock valve plate descends, and blocks water inlet.The water tank water intake of this water feed apparatus is subjected to artificial control, and is simple in structure, convenient and reliable operation, conserve water resource greatly.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a front view of the present utility model.

Fig. 2 is the novel broken section enlarged drawing in the A-A direction of this reality.

Among the figure: 1. water inlet pipe, the 2. limit cover that overflows, 3. junction plate, 4. knee, 5. ball float, 6. lever, 7. water tank, 8. torsion spring, 9. valve plate, 10. cover cap, 11. iron wires, 12. pedals, 13. fulcrum pins, 14. fixed heads, 15. removable pins.

The specific embodiment

As shown in Figure 1, be provided with water inlet pipe 1 above water tank 7, water inlet pipe 1 is curved shape.As shown in Figure 2, horizontal level, upper semi-circle place at water inlet pipe 1 open a notch, with the limit of a flat tube shape that matches with notch overflow cover 2 and water inlet pipe 1 sealing, there is the cover cap 10 of perforate the top of the excessive cover 2 of limit, there are a valve plate 9 upper ends to pass cover cap 10, the lower end can put in the inner chamber knee-action of excessive cover 2 of limit and water inlet pipe 1, its shape and water inlet pipe 1 match, but the water inlet of shutoff water inlet pipe 1 or open the intake tunnel of water inlet pipe 1, fixing a plate 3 in the upper end of valve plate 9, the other end of junction plate 3 is connected with lever 6.As shown in Figure 1, be provided with a fulcrum pin 13 in the appropriate position of lever 6, the other end of lever 6 is fixed a ball float 5, and ball float 5 is stretched in water tank 7.Lever 6 is the fulcrum rotation with fulcrum pin 13, be provided with foot-operated tripping mechanism in the lower right of lever 6, knee 4 in this mechanism drives a torsion spring 8 at bend, there are fixed head 14 and removable pin 15 to support, connect an iron wire 11 in the lower end of knee 4, the pedal 12 that is connected with iron wire 11 other ends is placed on the ground, by foot pedal 12 downwards the time, knee 4 is the fulcrum rotation with removable pin 15, the just spinning movement of the upper end of knee 4, thus release is to the support of lever 6, lever 6 and ball float 5 descend because of deadweight, it is up to drive valve plate 9, and the intake tunnel of opening water inlet pipe 1 makes water tank 7 water inlets, along with the rising of water tank 7 middle water levels, ball float 5 also rises to setting height because of the impetus of buoyancy, when lever 6 rose to the upper end of the knee 4 of homing, interlock valve plate 9 dropped to the end, thus shutoff the intake tunnel of water inlet pipe 1.

Claims
