For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the description of the present invention, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0035] Please refer to Figure 1-Figure 3 A normal pressure closed domestic water tank comprises a water tank body 1, a first partition plate 2, a second partition plate 3, a third partition plate 4, a plurality of support columns 6 and a plurality of pipes 5.

[0036] like Figure 1 and 3 As shown, the interior of the water tank body 1 has a water storage space for storing living water; a first partition 2 is provided in the water storage space along the height direction to divide the water storage space into a first chamber and a second chamber; a second partition 3 is horizontally arranged in the first chamber to divide the first chamber into a first area 1a and a second area 1b, and the first area 1a is located above the second area 1b; a third partition 4 is horizontally arranged in the second chamber and can slide along the height direction of the second chamber to divide the second chamber into a third area 1c and a fourth area 1d, and the third area 1c is located above the fourth area 1d, and the fourth area 1d is provided with a water outlet; the first area 1a is connected with the second area 1b and the third area 1c, the second area 1b is connected with the fourth area 1d, and the third area 1c is connected with the fourth area 1d.

[0037] In this embodiment, the second chamber has an upper dead point position and a lower dead point position, and the third partition 4 slides between the upper dead point position and the lower dead point position. By setting the upper dead point position, it is possible to avoid a situation in which too much living water in the fourth area 1d causes the living water in the first area 1a to enter the fourth area 1d; by setting the lower dead point position, it is possible to avoid a situation in which too little living water in the second area 1b causes the living water in the second area 1b to enter the third area 1c.

[0038] In this embodiment, Figure 3 As shown, the volume of the first area 1a is larger than the volumes of the second area 1b, the third area 1c and the fourth area 1d; the living water of the first area 1a is supplied to the second area 1b and the third area 1c, and a larger first area 1a is set to better meet the usage needs.

[0039] In this embodiment, Figure 3As shown, several support columns 6 connect the second partition 3 and the inner wall of the water tank body 1. Since the volume of the first area 1a is relatively large, when there is a gap in the second area 1b, the living water in the first area 1a will cause a relatively large pressure on the second partition 3. By setting up several support columns 6, the second partition 3 can be supported to avoid the second partition 3 being crushed.

[0040] In this embodiment, Figure 2 As shown, the first area 1a and the second area 1b are provided with a pressure relief port 13, which can release the domestic running water in the first area 1a and the second area 1b, so as to facilitate maintenance and cleaning.

[0041] In this embodiment, a water inlet 11 is provided in the first area 1 a to facilitate replenishing domestic water into the water tank body 1 .

[0042] In normal state, such as Figure 4 As shown, the first area 1a, the second area 1b and the fourth area 1d are filled with domestic water, which is supplied to the outside through the water outlet; Figure 5 As shown in FIG. 1 , when the water supply pressure drops, the domestic water in the first area 1a enters the third area 1c. Figure 6 As shown, as the amount of living water in the third area 1c increases, the living water in the third area 1c exerts a downward gravity on the third partition 4 and forms pressure on the living water in the fourth area 1d, increasing the water pressure at the water outlet; Figure 7 As shown, when the living water in the fourth area 1d is consumed, the living water in the second area 1b and the third area 1c enters the fourth area 1d, and under the action of buoyancy, the third partition 4 is restored.

[0043] It should be noted that, when the domestic water in the fourth area 1d is exhausted, the domestic water in the third area 1c enters the fourth area 1d first.

[0044] Specifically, Figure 3 As shown, the first partition plate 2 is provided with a first through hole and a second through hole, and the first area 1a is connected to the third area 1c through the first through hole; the second area 1b is connected to the fourth area 1d through the second through hole; the second partition plate 3 is provided with a third through hole, and the first area 1a is connected to the third area 1c through the third through hole; the third partition plate 4 is provided with a fourth through hole, and the third area 1c is connected to the fourth area 1d through the fourth through hole.

[0045] Several pipes 5 are respectively arranged at the first through hole, the second through hole, the third through hole and the fourth through hole, and valves that can be remotely controlled to open are provided in the pipes 5; by setting the valves, the flow of living water in the first area 1a, the second area 1b, the third area 1c and the fourth area 1d is controlled.

[0046] In this embodiment, the pipe 5 arranged at the first through hole is also provided with a one-way valve, so that the liquid can only enter the third area 1c from the first area 1a, so that the living water in the third area 1c can replenish the fourth area 1d, and prevent the living water in the third area 1c from flowing back to the first area 1a. The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
