The working principle is as follows: when the device is used, the device is arranged in a water tank (a water tank of a water heater), the mounting plate 1 is fixed on the side wall of the bottom of the water tank, when hot water is used, the water outlet valve 11 is opened, the hot water in the water tank flows into the hose 14 from the water inlet 1401, then flows into the drain pipe 10 through the choke valve 3 and the connecting pipe 13, and flows out from the water outlet valve 11, and at the moment, a user can normally use the hot water in the water tank;
when the outlet valve 11 is closed, the hot water in the water tank stops flowing outwards, and at this time, the air pump 12 is started, so that the air pump 12 fills air into the interior of the water outlet pipe 10, so that the air filled into the interior of the water outlet pipe 10 flows in the opposite direction against the hot water in the water outlet pipe 10, and at this time, the hot water in the water outlet pipe 10 flows along the connecting pipe 13, the choke valve 3 and the hose 14 in sequence and flows into the interior of the water tank from the water inlet 1401, so that the hot water in the water outlet pipe 10 is emptied, and thus the water outlet pipe 10 (located outdoors) is prevented from being frozen; when the hot water in the drain pipe 10 is drained, the floating ball 7 in the liquid blocking valve 4 loses the buoyancy of the liquid to enable the liquid blocking valve 4 to be conducted, at the moment, the gas injected by the air pump 12 enters the air bag 9 along the air pipe 8, so that the air bag 9 with the water inlet 1401 floats out of the water surface of the water tank, and then the hot water in the water tank is effectively prevented from entering the drain pipe 10;
when hot water is needed, the water outlet valve 11 is opened, so that the air inside the air bag 9 is instantly exhausted from the water outlet valve 11, and then the air bag 9 loses the floating function, at this time, the water inlet 1401 sinks into the hot water, so that the hot water inside the water tank enters the hose 14 from the water inlet 1401, and flows through the choke valve 3, the connecting pipe 13 and the water outlet pipe 10 in sequence and is exhausted from the water outlet valve 10, and the normal use of the hot water by a user is realized.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
