Abstract

The utility model discloses a sealed pneumatic water-flushing cistern, which comprises a cistern body, and a water inlet pipe and a water outlet pipe arranged on the lower part of the cistern body. The upper part of the cistern body is also provided with a pressure regulation device which is composed of a guide bushing, a connecting rod, a floating body, and a rubber stopper. The guide bushing partially extends into the cistern body from top to bottom, and the connecting rod passes through the guide bushing, and then extends into the cistern body; the lower end of the connecting rod is fixedly connected with the floating body, and the rubber stopper is fixedly connected with the connecting rod between the floating body and the guide bushing. The utility model with the structure has the advantages of high water output, quick water outlet, adjustable water level, good sealing effect, etc. The utility model is an ideal product for replacing the water-flushing cistern in a traditional toilet.

Description

Blanket gas pressure type flushing tank

The utility model relates to the technical field of lavatory flushing storage tank.

Traditional use in toilet flushing tank, its structure is simpler, is an airtight cavity volume, and cavity volume is provided with water inlet pipe and outlet pipe in the bottom, utilize air airtight in the cavity volume to produce certain hydraulic pressure, forms the current of certain impulse force when outlet pipe is opened.But after the flushing tank of structure used certain hour like this, the air in the cavity volume can leak, and causes water tank internal gas pressure deficiency, and the case internal memory water yield is more and more, but water yield is few, and water outlet is slow.When water tank air pressure deficiency occurring, only close water inlet pipe, allow the interior water of cavity volume be emptied completely to replenish air from outlet pipe, water tank could recover normal operating conditions.

The purpose of this utility model is the weak point that overcomes above-mentioned prior art, and the blanket gas pressure type flushing tank that a kind of hydraulic pressure is sufficient, water outlet is fast and the water yield is adjustable is provided.

The purpose of this utility model is achieved by the following technical solution: blanket gas pressure type flushing tank, comprise casing, be loaded on the water inlet pipe and the outlet pipe of lower box, special feature is that casing top also has barometric control unit, and barometric control unit is made of guide thimble, connecting rod, buoyancy aid, rubber stopper; Guide thimble from top to bottom part stretches in the casing, and connecting rod then passes guide thimble and stretches in the casing again, and the connecting rod lower end is fixed with buoyancy aid, is fixed with rubber stopper on the connecting rod between buoyancy aid and the guide thimble.Further, external screw thread is arranged on the guide thimble, spinning with the screw of casing top cooperates, and the guide thimble upper portion side wall also has pore.

Below in conjunction with drawings and Examples structure of the present utility model and advantage are further described.

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

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the sectional view of Fig. 1;

Fig. 4 is the state variation schematic diagram.

Referring to Fig. 1-Fig. 4, the barometric control unit that present embodiment mainly comprises casing 1, is loaded on the water inlet pipe 2 of casing 1 bottom, outlet pipe 3 and is loaded on casing 1 top, barometric control unit is made of guide thimble 4, connecting rod 5, buoyancy aid 6, rubber stopper 7, guide thimble 4 outer walls have screw thread and cooperate with the screw on casing 1 top, guide thimble 4 parts spin and stretch in the casing 1, connecting rod 5 passes guide thimble 4 and stretches in the casing 1, the lower end of connecting rod 5 is connected with buoyancy aid 6, and the connecting rod place of buoyancy aid 6 tops also is fixed with a rubber stopper 7 that can seal guide thimble 4 lower ends.

The course of work is such: at first water is entered in the casing 1 by water inlet pipe 2, along with inflow increases, buoyancy aid 6 continuous buoyance lifts, move on the drivening rod 5 simultaneously, casing 1 internal gas pressure is communicated with atmospheric pressure, rises to the lower port of rubber stopper 7 sealing guide thimbles 4 until buoyancy aid 6, after guide thimble 4 is sealed by rubber stopper 7, casing 1 internal gas pressure is hedged off from the outer world, and water level continues to rise in the casing 1, until the hydraulic pressure identical (as shown in Figure 3) of casing 1 internal gas pressure with water inlet pipe 2.Discharge water when flushing when opening outlet pipe 3, water is flowed out by outlet pipe 3, drawdown in the casing 1, buoyancy aid 6 moves down thereupon, in case the rubber stopper 7 on the connecting rod 5 breaks away from guide thimble 4, air pressure in the casing 1 is communicated with external atmosphere pressure at once, the water that quickens in the casing 1 flows out, move down into limit position until connecting rod handle 8--be guide thimble 4 upper ends, although connecting rod handle 8 might seal guide thimble 4 and extraneous being communicated with, but guide thimble 4 upper portion side wall have pore 9, guarantee that the atmosphere pressure energy continuingly acts in the water tank (as shown in Figure 4).So intake, go out water circulation, remain enough air pressure in the casing 1.

In sum, the utlity model has obvious superiority:

1, the position by adjusting nut can change the degree of depth that guide thimble stretches into casing, adjusts Buoyancy aid can regulate the installation of water in the casing at the height of water tank;

2, be communicated with external atmosphere pressure all the time in the casing during water outlet, the hydraulic pressure height, water outlet is fast, the water yield is sufficient:

3, good sealing effect, easy to use.

Claims

1, blanket gas pressure type flushing tank comprises casing, is loaded on the water inlet pipe and the outlet pipe of lower box, and it is characterized in that: casing top also has barometric control unit, and barometric control unit is made of guide thimble, connecting rod, buoyancy aid, rubber stopper; Guide thimble from top to bottom part stretches in the casing, and connecting rod then passes guide thimble and stretches in the casing again, and the connecting rod lower end is fixed with buoyancy aid, is fixed with rubber stopper on the connecting rod between buoyancy aid and the guide thimble.

2, flushing tank according to claim 1 is characterized in that external screw thread is arranged on the guide thimble, and spinning with the screw of casing top cooperates, and the guide thimble upper portion side wall also has pore.
