Multifunctional water storage and supply tank

[0024] Example 1

[0025] Such as figure 1 The multifunctional water storage and water supply tank shown includes a cylindrical tank body with closed ends 1, four supporting legs 2 installed at the bottom of the tank body for supporting the tank body, and a barometer 3 installed on the top of the tank body 1 And the pressure switch 4, the upper left side of the tank 1 is provided with a water inlet 11, and the water inlet pipe 51 is inserted into the water inlet 11 by connecting the water inlet valve 52 and the check valve 53 to communicate with the inside of the tank 1, in the tank 1 There is a water outlet hole 12 on the lower right side of the, and the outlet pipe 61 is connected with the tank body 1 and then extends out of the tank body 1. The tank body 1 is also provided with an automatic sealing device 7 that can be automatically closed when the water level rises to a certain position. , A cleaning device 8 is also provided inside the tank 1. The two ends of the tank body 1 a

[0029] Example 2

[0030] Such as image 3 As shown, the outside of the cylinder of the automatic sealing device is provided with a dust cover 9 which is a cylindrical cover whose upper end is sealed and is buckled on the outside of the cylinder on the wall of the dust cover 9 There is a ventilation net 91.

[0031] With the above structure, dust can be effectively prevented from entering the tank body, and the tank body is clean and hygienic.

[0032] Example 3

[0033] Such as Figure 4 As shown, a vertical column 76 is fixedly installed at the center of the upper end surface of the blocking door 72, the vertical column can rotate with the blocking door 72, and a fixing plate 711 is installed above the wall of the cylinder 71, on the fixing plate 711 A contact switch 712 is installed, and the contact 713 of the contact switch 712 is arranged such that when the column 76 is in the vertical direction, the contact 713 contacts the column 76; on the inner wall of the cylinder 71 there are two corresponding ones that are perpendicular to the orbital space where the column 76 rotates. There are two shaft seats 771 in the cylinder 71, a crankshaft 77 mounted on the shaft seat 771 at both ends, the two ends of the crankshaft 77 are horizontal, and the middle part is an n-shaped arch 772. The arch 772 is lower than the top of the column 76 when it rotates to the highest point. One end of the crankshaft 77 extends out of the cylin
