Abstract

The utility model discloses an air bag type pressure flushing cistern, which comprises a cistern body, and a water inlet pipe and a water outlet pipe which are arranged on the lower part of the cistern body. The upper part of the cistern body is also provided with a sealing pressure adjusting device which is composed of an elastic air sac and an air valve which is hermetically connected with the elastic air sac. Moreover, the air valve is arranged outside the cistern body, and is hermetically fixedly connected with the cistern body, and the elastic air sac is arranged in the cistern body. The utility model with the structure has the advantages of high water output, high water pressure, adjustable water storage, good sealing effect, etc. The utility model is an ideal product for replacing the cistern of the traditional toilet.

Description

Air-bag type pressure flushing tank

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

Traditional use in toilet flushing tank, it is simple in structure, 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 air-bag type pressure 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: air-bag type pressure flushing tank, include casing, be loaded on the water inlet pipe and the outlet pipe of lower box, the blanket gas pressure regulator also is equipped with on casing top, this device is made of elastic bag and air valve, air valve and elastic bag are tightly connected, and air valve is loaded on outside the casing and with box sealing and is connected, and elastic bag then is loaded in the casing.Further, air valve is made of valve body, valve inside, pressure mother, and valve body lower portion stretches in the casing and is connected with air sac sealing, press female valve inside to be pressed in the valve body, whole air valve by nut and sealing ring fit sealing above casing.

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 structure schematic diagram of Fig. 1.

Referring to Fig. 1-Fig. 3, the blanket gas pressure regulator that present embodiment 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.The blanket gas pressure regulator is made of elastic bag 4 and air valve 5, air valve 5 includes valve body 51, presses mother 52, valve inside 53, it is outer also by nut 6 and sealing ring 7 and casing 1 fit sealing that valve body 51 tops stretch out in casing 1, make the sealing that is hedged off from the outer world of whole box body 1 inner chamber, valve body 51 bottoms are stretched in the casing 1 and with elastic bag 4 and are tightly connected, and press female 52 valve inside 53 is pressed in the valve body 51.

The course of work is such, at first squeeze into the gas of 2-6kg pressure in the elastic bag 4 by air valve 5, air valve 5 with air seal in elastic bag 4, water inlet pipe 2 discharges water and enters in the casing 1 then, because surplus has certain air in when casing 1 has just been brought into use, the water yield in the casing 1 is differed by the effect of surplus gas pressure to be full of casing 1 surely or to flood elastic bag 4, but as long as dash discharge water several times after, surplus gas in the casing 1 is pulled away, liquid level during water inlet later in the casing 1 can flood, act on the elastic bag 4, because the effect of hydraulic pressure, when being full of water in the casing, elastic bag 4 understands so and local distortion is dwindled.Discharge water when flushing when opening outlet pipe 3, the gas pressures in the elastic bag 4 directly act on the water in the casing 1, play the effect to the water pressurization, and the water that quickens in the casing 1 flows out.When water dash fully put after, in the air bag 4 air fully with water tank in water isolated, still maintain the air pressure of elastic bag 4 in the casing 1, like this, assurance is washed by water at every turn, is intake and all maintains enough pressure.Certainly, in actual use, can by the air pressure in the air valve increase and decrease air bag, and regulate the interior water amount of casing according to the size of hydraulic pressure.

In sum, the utlity model has obvious advantage:

1, remains certain air bag air pressure in the casing, all protect when each punching is discharged water Hold enough pressure, the hydraulic pressure height, water outlet is fast, the water yield is sufficient;

2, by the air pressure size of the adjustable solar term capsule of air valve, the moisture storage capacity of change casing;

3, good sealing effect need not be regulated repeatedly, and is easy to use.

Claims

1, air-bag type pressure flushing tank, include casing, be loaded on the water inlet pipe and the outlet pipe of lower box, it is characterized in that: the blanket gas pressure regulator also is equipped with on casing top, this device is made of elastic bag and air valve, air valve and elastic bag are tightly connected, and air valve is loaded on outside the casing and with box sealing and is connected, and elastic bag then is loaded in the casing.

2, pressure flushing tank according to claim 1, it is characterized in that air valve is made of valve body, valve inside, pressure mother, valve body lower portion stretches in the casing and is connected with air sac sealing, press female valve inside to be pressed in the valve body, whole air valve by nut and sealing ring fit sealing above casing.
