Description

The two-section water-closet tank supplies water and postpones water-supply structure

The utility model relates to a kind of two-section water-closet tank and supplies water and postpone water-supply structure, refers to especially a kind ofly not only can postpone water but also can have the water-saving closet that two-section supplies water.

The water capacity of present high level cistern or water tank and the integrated water tank of toilet is few, its structure as shown in Figure 1, this water-closet tank adopts the breakdown of a valve A, make a U type oral siphon B produce the syphon effect, the water in the water tank C is sucked and enters in the toilet through drain gully D, its shortcoming for the toilet tap of this this kind of oral siphon design because of having only single discharging quantity of water, the not only large and small identical water yield flush toilet (crouching formula or seat formula are all same) of just all using causes water waste.

Second kind of known embodiment and for example shown in Figure 2 shows among the figure, and this known second kind of embodiment and first figure have same disadvantages.The user is large and small just all only to provide a kind of discharging quantity of water, causes water waste.And the another kind of shortcoming of this second kind of embodiment, for establish a valve E1 in drain gully B, this valve E1 is generally all made by the rubber material, and it has certain weight, therefore makes the valve breakdown when the user spurs pull bar E2, and the water in the water tank flows out through drain gully, when not flowed about H height, this valve promptly can be closed and be fallen into a mouthful E, and the each neither energy of water in the water tank has been dashed, discharging quantity of water deficiency when causing stool, the problem that discharging quantity of water again can be too many during urine.

The purpose of this utility model is to be to provide a kind of two-section water-closet tank that water and delay water-supply structure are provided, the shut-in time that makes it to have the two-section flushing function concurrently and can postpone water inlet, give toilet and increase output, and toilet can be rinsed totally.

The purpose of this utility model is achieved in that a kind of two-section water-closet tank supplies water and postpones water-supply structure, includes water tank, and water tank and be provided with water inlet pipe, ball float and be provided with tap, and this tap has and falls into water or overflow pipe; Reach and fall into water oral-lateral and be provided with water inlet, it is characterized in that a described water inlet and be provided with the inverted U oral siphon; Another water inlet then is provided with valve.

The purpose of this utility model also can be realized that by following measure wherein the valve of two drain gullies of tap can be the valve that is provided with aqua storage tank, and this valve is provided with an aqua storage tank, aqua storage tank has aperture, the aqua storage tank side is provided with a screw rod, and screw rod can be the balancing weight spiral shell and establishes, and spurs this valve with pull bar.Above-mentioned U type entry pipe end is established a minor valve, and this minor valve top is connected with a lead-in wire and a pull bar.

Effect of the present utility model is, because this tap is provided with two water inlets, to form the water-saving design that two-section supplies water and gives toilet; Another characteristics of the present utility model are provided with the valve of a tool late release for this, give toilet to increase output, toilet can be rinsed totally, thereby reach the purpose of this utility model.

The explanation of accompanying drawing drawing:

Fig. 1 is the sectional view of water tank in the prior art.

Fig. 2 is second kind of embodiment of water tank in the prior art.

Fig. 3 embodiment one vertical view of the present utility model.

Fig. 4 embodiment one of the present utility model analyses and observe and action diagram.

Fig. 5 embodiment one of the present utility model analyses and observe and action diagram.

Fig. 6 embodiment two of the present utility model analyses and observe and action diagram.

It is as follows to describe the utility model in detail below in conjunction with embodiment and accompanying drawing thereof;

Fig. 3～Figure 5 shows that first kind of embodiment of the present utility model, show among the figure, present embodiment includes water tank 1, water inlet pipe 2 and controls ball float 20 that whether water inlet pipe 2 intake, and tap 3, this tap 3 is provided with drain gully 30 and two

water inlets

31,32, and wherein water inlet 31 is to be provided with a U type oral siphon 4 to stretch and establish in the water box slot 10, and the position of its arrival end 40 is looked closely its desire and supplied with the water yield that flows into toilet and decide.And this oral siphon 4 is to be controlled by a minor valve 5, these minor valve 5 tops 50 are connected with pull bar 51 to go between, and the below is provided with one 52, an axle 52 and a sheathed spring 53, can utilize pull bar 51 to be pulled thus, valve port 54 with breakdown minor valve 5, so that the water in the water box slot flows down by valve port 54, and makes water pipe 4 produce siphonages simultaneously, to draw the water in the water box slot, so when pull bar 51 is loosed one's grip, minor valve 5 is closed, and this oral siphon 4 also can continue to sink water liquid, and is low up to the arrival end 40 of the water liquid aspect ratio oral siphon 4 of water box slot, this action that draws water just can stop, and toilet first section water supply function that few water yield supplies water is provided.

Inferior water inlet 32 is established a valve 6 in addition, the aqua storage tank 60 of these valve 6 one sides and tool disjunctor, and the diapire of this aqua storage tank 60 is also established an aperture 61, and then be provided with a balancing weight 62 in its inboard appropriate location, these balancing weight 62 spiral shells are located at screw rod 63, to adjust the position of counterweight, the shut-in time of decision valve 6.This valve is established aqua storage tank 60 again, storage full water in water box slot 10, and with pull bar 64 pulling valves 6, make valve 6 by breakdown, to make the water in the water box slot flow in the toilet fast through water inlet 32, in this simultaneously, because of containing water liquid in the aqua storage tank 60, this water liquid need treat that the water in the water box slot flows out to when lower than the position of its aperture 61, water in the aqua storage tank 60 just can begin to flow out, and the shut-in time that this can postpone valve 6, makes water inlet pipe 2 replenish the interior water of water box slot, flow to toilet through water inlet 32 immediately, less than the weight of valve 6 (balancing weight still has the part decision valve closing time certainly), this valve promptly can be closed until aqua storage tank 60 weight, in the toilet that stops to supply water, go into toilet and be formed with to postpone to supply water and supply to put a large amount of water, with the problem of subsidiary water tank water storage deficiency.And form second section water supply function, to cooperate the flush action of stool or urine.

Be illustrated in figure 6 as second kind of embodiment of the present utility model, show among the figure, second present embodiment is provided with two groups can be for the valve 6 that postpones to supply water, promptly two

water inlets

31,32 adopt 6 designs of identical valve, two-section is supplied water, all have a function of supplementary feed, to cooperate actual demand.And or this tap can be provided with overflow pipe 7, to prevent water inlet pipe 2 the spilling water purposes when if fault is arranged.And water inlet 31,32 arrives the design that outlet 31A, the 32A of drain gully adopt diverse location, and its purpose improves in the speed that makes bath go into drain gully, and avoids current to rush at the function person of another valve.
