Description

a water storage container

technical field

The utility model relates to a water storage container.

Background technique

The existing water storage container mainly includes a shell and a flexible inner bag arranged in the shell. A water storage cavity is formed in the flexible inner bag, and an air cavity is formed between the flexible inner bag and the shell. The casing is provided with air holes and water inlet and outlet holes connecting the inside and outside of the casing, and the opening of the flexible inner bag is fixed on the top of the casing and communicated with the water inlet and outlet holes. Since the flexible inner bag is hung on the top of the housing, when the flexible inner bag is filled with water, the flexible inner bag is easily broken due to gravity, thereby affecting the service life and performance of the water storage container.

Contents of the invention

In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides a water storage container with a simple and compact structure, a flexible inner bag that can move freely, and will not break.

The technical solution of the utility model to solve the technical problem is: a water storage container, including a shell, and a flexible inner bag arranged in the shell, a water storage chamber is formed in the flexible inner bag, and the flexible inner bag and the flexible inner bag An air cavity is formed between the housings, air holes and water inlet and outlet holes connecting the inside and outside of the housing are provided on the housing, a connecting pipe is provided in the housing, and one end of the connecting pipe is connected to the The inlet and outlet holes are connected, and the other end of the connecting pipe is located at the bottom of the housing and connected with the opening of the flexible inner bag.

Further, both ends of the connecting pipe are respectively connected to the water inlet and outlet holes and the mouth of the flexible inner bag through sealed joints, which is convenient for connection. The connection method between the sealing joint and the flexible inner bag is as follows: the opening of the flexible inner bag is ultrasonically welded or thermally fused to the sealing joint. Alternatively, the mouth of the flexible inner bag is sealed and clamped on the sealing joint by a clamping block.

Furthermore, the air hole is provided with a valve core through which gas can be injected into the air cavity. When water is discharged, the water in the water storage cavity can automatically flow out from the connecting pipe and the water inlet and outlet holes sequentially under the pressure of the air cavity.

Further, the connecting pipe is a hose, which can move freely in the casing after the flexible inner bag is filled with water. The connecting pipe can also be a hard pipe, but the effect of the hose is better.

Further, the housing includes an upper housing and a lower housing, the lower peripheral edge of the upper housing is sealed and welded to the upper peripheral edge of the lower housing, and the water inlet and outlet holes are arranged in the upper housing The air hole is located on the top of the lower shell. Alternatively, the housing includes a bucket body and a bucket cover screwed to the mouth of the bucket body, and the water inlet and outlet holes and air holes are both provided on the bucket cover. The shell is a split structure, easy to install.

Further, the housing is injection molded from PP material or blow molded from PET material, which has good strength.

Further, the flexible inner bag is made of butyl rubber material, PP material, PE material, PP material and PE material, PP material and PA material, or PE material. It is composited with PA material or composited with PP material, PA material and PE material. The flexible inner bag is provided with an antibacterial layer, which is more safe and hygienic.

When the utility model is injecting water, the external water enters into the water storage chamber of the flexible inner bag through the water inlet and outlet holes and the connecting pipe in turn to store water. Since the housing is provided with air holes, the air in the air chamber can be discharged from the air holes; When the water comes out, the water in the water storage chamber of the flexible inner bag can flow out from the connecting pipe and the water inlet and outlet holes in turn, while the external air will directly enter the air cavity from the air hole, compressing the flexible inner bag to shrink, so that the water in the water storage chamber The water flows out stably and smoothly, and the external air will not enter the water storage chamber, which can effectively prevent the water in the water storage chamber from being polluted. After a valve core is arranged in the air hole, the air chamber can be provided with a certain air pressure, and the water in the water storage chamber can be forced to flow out automatically when water is discharged.

The beneficial effect of the utility model is that: adopting the above-mentioned structure, the mouth of the flexible inner bag is connected with the water inlet and outlet holes of the casing through the connecting pipe, and the flexible inner bag can move freely in the casing, even if the flexible inner bag is filled with water It will break due to the gravity of water and has a long service life.

Fig. 2 is another embodiment of the present utility model.

detailed description

The utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment.

Embodiment one

Referring to FIG. 1 , a water storage container includes a housing and a flexible inner bag 1 disposed in the housing. A water storage chamber 2 is formed in the flexible inner bag, and a water storage chamber 2 is formed between the flexible inner bag and the housing. There is an air chamber 3, and the housing is provided with air holes 4 and water inlet and outlet holes 5 communicating with the inside and outside of the housing, and a connecting pipe 6 is arranged inside the housing, and one end of the connecting pipe is connected to the water inlet and outlet. The holes 5 are connected, and the other end of the connecting pipe is located at the bottom of the housing and connected with the mouth of the flexible inner bag 1 .
