Description

Automatic air supply air pressure water-saving water tank

The utility model relates to a water tank, in particular to an airtight water tank used for toilets and sanitary ware.

Existing air pressure water tanks used for flushing toilets and sanitary ware, after a period of use, the air stored in the tank will take away a part of the air each time the water is drained during use to form a vacuum. Therefore, the part of water remaining in the tank cannot be discharged normally, and the momentum gradually weakens when the air pressure water tank is flushed, failing to reach the set flushing effect. The existing way of remedy is to adopt manpower to close the water inlet valve of the water tank, loosen the hose, open the drain valve, etc. to allow air to enter the casing, which obviously brings a lot of trouble to the user and causes the existing air pressure type The water tank faded.

The purpose of the utility model is to provide an automatic air-supplement air pressure water-saving water tank that can automatically enter the airtight water tank without manpower.

The purpose of this utility model is achieved in the following way: the automatic gas supply air pressure water-saving water tank includes: a box body, a water inlet part and a water outlet part, and the box body is a closed container with a tap water inlet and a water outlet on it ; Inside the box, the lower part is the water storage part, and the upper part is the compressed air part. It is characterized in that: the tap water inlet is provided with an automatic air supply valve or an automatic air supply check multifunctional valve.

The above-mentioned design, the main key is to set another patent of the applicant at the tap water inlet, i.e. an automatic air supply valve or an automatic air supply check multifunctional valve. The function of this valve can automatically supplement the air in the water tank while water is entering, so that the air can automatically enter the closed water tank without using manpower.

Further description will be given below by accompanying drawings and embodiments.

Fig. 1 is the structural representation of the utility model through partial cross-section;

The structural representation of the automatic air supply valve that Fig. 2 the utility model adopts;

Fig. 3 is the schematic diagram of the structure of the automatic air supply check multifunction valve adopted by the utility model;

4 and 5 are schematic diagrams of the utility model in use.

As shown in Figure 1-3: the utility model includes: a box body 1, a water inlet part and a water outlet part, the box body 1 is a closed container with a tap water inlet 2 and a water outlet 3 on it; , the lower part is the water storage part 5, and the upper part is the compressed air part 6, which is characterized in that: the tap water inlet 2 is provided with an automatic air supply valve 4 or an automatic air supply check multifunctional valve 4'. Wherein, the automatic air supply valve 4 is composed of tap water A water inlet 10, air inlet 11, vacuum chamber 12 and water outlet 15, and the vacuum chamber 12 is provided with a water flow nozzle 13, and the vacuum chamber 12 is followed by a water-air mixing chamber. 14. The water outlet 15 and the flared mouth 16 are provided with a non-return object 17 after the air inlet 11 and before the vacuum chamber 12 . Wherein, behind the water inlet 10, a non-return chamber 18 is provided at the front of the water flow nozzle 13, and a non-return piston 19 is arranged in the non-return chamber 18, and a non-return spring 20 is sleeved on the non-return piston 19. In this way, when tap water enters from the water inlet, the check piston and spring are pushed up, and the water enters the check chamber; the water reaches the water nozzle through the pipeline to produce high-speed jet, and quickly takes away the water and air around the nozzle, instantly making the nozzle The space around the nozzle forms a vacuum; at this time, the water flow continues to spray, and the non-return object, such as a leather cup, is sucked away under the action of the vacuum, and the air is automatically filled into the vacuum chamber along the air inlet hole, realizing automatic air replenishment. The high-speed sprayed water and supplemented air meet at the water-air mixing chamber, and after mixing, they go to the water outlet. By means of a flared rotary diffuser the flow is diverted to the tank of a closed container. That is to say, each time the airtight container is filled with water, a part of the air is automatically replenished. When the pressure of the closed container is equal to the water pressure of the water supply pipe, the water supply stops. The non-return spring resets the non-return piston to press the water inlet, realizing the one-way water inlet non-return. At the same time, the water flow stops jetting at high speed, the cup resets to block the air inlet hole, the air stops entering, and the water in the vacuum chamber cannot leak out along the air hole. The whole process of carrying out automatic air supply and one-way non-return along with the tap water supply process has just been realized.

As shown in Figures 4 and 5: the utility model can be used in the closed water tank 21 of the toilet 23, and it is provided with automatic gas-supplementing check multifunctional valve 4 ' in tap water A water inlet 22. It can also be used in single or multiple squatting pans 30 of public toilets or closed water tanks 31 for toilet flushing, and the tap water A water inlet 32 is provided with an automatic gas-supplementing check multifunctional valve 4 '. It can be seen that the utility model has a wide range of uses, and it is convenient to manage in public places, and has greater advantages in sanitation and cleaning.

The automatic air supply air pressure water-saving water tank has the following advantages:

1. The box body adopts a sealed structure, there are no vulnerable parts in the box, it is durable, and there is no maintenance trouble;

2. The cabinet is small in size, occupies a small space, and the whole operation system is simple in structure, easy to use and install, and low in cost;

3. Make full use of the energy of tap water under pressure, store it in the box, release it quantitatively instantly, and receive a good flushing effect with high flushing flow rate, high flushing intensity, and good decontamination and deodorization;

4. It is precisely because of the large flow rate and high strength that the purpose of water saving is achieved. Compared with the traditional high and low water tanks, which rely on the weight and drop of water storage to obtain flushing power, water is saved;

5. The successful research of the multi-function valve with automatic air replenishment and non-return has made it possible for the air pressure water tank to have a long-term and continuous strong flushing force;

6. The automatic air supply valve uses tap water to automatically replenish air during the water supply process, without manpower or other power, which is energy-saving and convenient;

7. The check valve is set at the bottom of the automatic air supply valve and operates simultaneously with the entire system to automatically prevent the water stored in the tank from flowing backwards.

To sum up, the automatic air supply air pressure water-saving water tank will have comprehensive good social benefits such as energy saving, water saving, no clogging, low cost, and easy promotion and use.
