The drawings are simplified schematic representations which merely illustrate the basic structure of the utility model and therefore show only the structures which are relevant to the utility model.
Referring to fig. 1-4, the water tank has a water tank body 100 and a water tank cover 200, wherein the water tank body 100 is provided with a water inlet 101, the water tank cover 200 is installed corresponding to the water inlet 101, the water tank cover 200 is provided with a sleeve 210 plugged at the water inlet 101, and a soft rubber plug 220 is installed in the sleeve 210.
Soft rubber plug 220 includes: the mounting part 221 and the flexible membrane 222 which can be attached to the inner wall of the sleeve 210 are tightly attached to the inner wall of the sleeve 210 under the action of no external force, so as to play a role in sealing.
The sleeve 210 is provided with an air intake passage (not shown) communicating with the outside; the flexible membrane 222 is punched under the action of external medium, the air inlet channel is opened, and external medium enters the water tank main body 100 from between the flexible membrane 222 and the inner side wall of the sleeve 210; the flexible membrane 222 is more tightly attached to the inner side wall of the sleeve 210 under the action of the internal medium, and the air inlet passage is closed to limit the outflow of the internal medium.
Here, the water tank cover 200 may be provided with an air intake hole connected to the air intake passage; the water tank cover 200 is provided with more than 2 air inlet holes, the aperture is 0.5-1.5mm, and under negative pressure in the water tank main body 100, external air can enter the air inlet channel through the air inlet holes and then flow into the water tank main body 100.
In use, when the air pressure in the tank body 100 is equal to the air pressure outside the tank body 100, the flexible membrane 222 is attached to the inner side wall of the sleeve 210 to prevent medium exchange.
When water in the water tank body 100 flows out from the water outlet, negative pressure is formed in the water tank body 100, the external pressure of the water tank body 100 is greater than the internal pressure of the water tank body 100, and then external air rushes out of the flexible membrane 222, and external air enters the water tank body 100 to be supplemented with air, and the air flow path is shown in the direction of small arrows in fig. 4.
When the water tank main body 100 is inverted, water in the water tank main body 100 flows into the soft rubber plug 220, water pressure acts on the soft rubber plug 220, and the soft membrane 222 is tightly attached to the inner side wall of the sleeve 210, so that the purpose of preventing water leakage is achieved; as shown in fig. 4, the tank of fig. 4 is not inverted, and if the tank is inverted, the hydraulic force is as shown in the solid large arrow direction of fig. 4.
