Abstract
The utility model relates to a water saving cistern used in a toilet. The utility model comprises a cistern body, a cistern cover, a water inlet, a water outlet valve, a draw rod, etc. The utility model is characterized in that the upper side of the draw rod is sheathed with a restoring spring, the lower part of the draw rod is provided with a tapered cover, and the bottom part of the draw rod is connected with a valve plug of the water outlet valve. The utility model adopts a sealing structure, which causes the inner structure of the cistern to be simplified, and the volume to be reduced, simultaneously, the discharged water is applied with a definite pressure to flush a urinal effectively, and the effect of water saving can be achieved.
Description
The utility model relates to the water tank with water-saving function that a kind of washroom uses.
The water supply volume of water tank is quite surprising in the washroom.Along with water resource is poor day by day, the problem of water saving of water tank more and more draws attention.Except adopting various means and technology to prevent the radiator leak, people are also noted that and can select corresponding water yield according to the quantity of excrements in the urinal, reach the purpose of water saving.Chinese patent 93225401.2 provides a kind of water-saving water tank, and the cock of water drain of this water tank both direction is to the left and right pulled, and realizes discharging water of two grades of different water yields of size.Although this utility model is simple in structure, also very practical, owing to only adopt discharging water of two grades of different water yields, so can't reach the purpose of effective water saving.To this, Chinese patent 93227279.7 provides a kind of low position tank water-saving device, and the feature of this device is to adopt proportion to control the outlet valve of water tank greater than the ball valve of water, reaches the purpose of step-less adjustment water yield.This utility model can reach the purpose of water saving, but also has certain defective, just very little the time, can cause hydraulic pressure not enough at water yield, can not reach fully, thoroughly, the requirement of flushing toilet bowl neatly.
The purpose of this utility model provides a kind of novel water-saving water tank just in order to overcome above-mentioned defective, and it can not only adjust the water yield arbitrarily, and improves developing result by the water of discharging is applied certain pressure, reaches the water saving purpose.
The utility model is to adopt following technical proposal to realize: this water-saving water tank comprises the pull bar in case lid, water inlet, outlet valve and the casing on casing and the casing, be with back-moving spring on the pull bar, pull bar top is passed the water tank case lid and is stretched out, the pull bar bottom is provided with cone-shaped hood, and the pull bar bottom is connected with the valve plug of outlet valve.Therefore,, just can open outlet valve, make cistern water-discharging as long as lift a lower link.After pull bar is lifted, under the effect of back-moving spring, reset, outlet valve is closed again.In fact, the water yield of water tank can be different next controlled by the height that pull bar is lifted.In addition, in the bottom of pull bar a cone-shaped hood is set, after pull bar was lifted, water entered the cone-shaped hood bottom from the edge of cone-shaped hood.During draining, cone-shaped hood is exerted pressure to water under the effect of back-moving spring, thereby improves developing result.
Simultaneously, hermetically-sealed construction is all adopted in casing of this water-saving water tank and the junction between case lid, case lid and the pull bar, makes whole tank seal.The water inlet of water tank directly is connected with running water pipe.Like this, during cistern water-discharging, the hydraulic pressure of tap water acts on again on the cone-shaped hood, has further improved the hydraulic pressure of cistern water-discharging.
The utility model is because integral body adopts hermetically-sealed construction, and running water pipe directly is connected on the water tank inlet, has saved the water intaking valve and the water-level control apparatus of common water tank, has simplified the internal construction of water tank, has dwindled the volume of water tank.Simultaneously, this water-saving water tank is when draining, and cone-shaped hood is applied in the water of discharge under the pressure dual effect of the elastic force of back-moving spring and tap water, so even the more a spot of water of discharge, also effective flushing toilet bowl reaches the effect of real water saving.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the cross-sectional schematic of water-saving water tank provided by the utility model.
Among the figure, 1, casing; 2, case lid; 3, water inlet; 4, outlet valve; 41, valve plug; 5, pull bar; 51, back-moving spring; 52, cone-shaped hood.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in the figure, employing zero RunddichtringO of the junction between casing (1) and case lid (2), case lid (2) and the pull bar (5) sealing.A cone-shaped hood (52) is fixed in pull bar (5) bottom, and this cone-shaped hood (52) adopts the medium-soft material to make.Like this, when pull bar (5) when upwards lifting, cone-shaped hood (52) will suitably shrink, and reduce lifting resistance.The bottom of pull bar (5) connects the valve plug (41) of outlet valve (4), and the back-moving spring (51) in the pull bar (5) is arranged between cone-shaped hood (52) and the case lid (2).The elastic force of back-moving spring (51) in inactive state, is also exerted pressure to valve plug (41) except the hydraulic pressure that can increase draining, improves the sealing performance of outlet valve (4), prevents radiator leak.Water tank inlet in the present embodiment (3) is arranged on the side of casing (1), directly is connected with running water pipe.This water-saving water tank in use, tap water is not closed, and can intake automatically like this, can increase the hydraulic pressure of cistern water-discharging again.
Claims (3)
1, a kind of water-saving water tank, comprise the pull bar (5) in case lid (2), water inlet (3), outlet valve (4) and the casing (1) on casing (1) and the casing (1), pull bar (5) top is passed case lid (2) and is stretched out, it is characterized in that being with on the pull bar (5) back-moving spring (51), pull bar (5) bottom is provided with cone-shaped hood (52), and pull bar (5) bottom is connected with the valve plug (41) of outlet valve (4).
2, water-saving water tank according to claim 1 is characterized in that hermetically-sealed construction is all adopted in the junction between casing (1) and case lid (2), case lid (2) and the pull bar (5).
3, water-saving water tank according to claim 1 and 2 is characterized in that described cone-shaped hood (52) adopts the medium-soft material to make.
