[0004] The rapid development of the household appliance industry has made people have higher and higher requirements for liquid heaters that are frequently used in daily life. Nowadays, there are many types of water boilers on the market, but the general functions are single and the structural design is unreasonable, which cannot make consumers convenient and effective. Automatically control the drinking water temperature, especially in order to prevent the water boiler from running dry, the general water boiler is equipped with a water shortage protection device, but the existing water boiler water shortage protection device generally uses a magnetic float device, and its structure is complicated , difficult to install, high cost

The invention discloses a water shortage protection device. The water shortage protection device comprises a heating pipe and a water receiving box, wherein the water receiving box is installed at the bottom of the heating pipe; a temperature sensing vane communicating with the bottom of the inner cavity of the heating pipe and convenient for sensing whether a temperature in the case of water shortage of the heating pipe exceeds a set value or not, a water shortage temperature controller and a waterproof button are arranged at one side of the water receiving box, a boss bulging towards one side is arranged on the temperature sensing vane, the boss is connected with an L-shaped sensing head in an extension manner, a sensing hole convenient for the L-shaped sensing head on the temperature sensing vane to stretch in the bottom of the inner cavity of the heating pipe is formed in the sidewall of the water receiving box, the corresponding water shortage temperature controller is installed at the rear side of the temperature sensing vane, and the waterproof button is installed on the water shortage temperature controller; and the temperature sensing vane is expanded with heat and the change is transferred to the water shortage temperature controller to switch off a power supply of the heating pipe to play a protection role in the case of water shortage of the heating pipe through the boss and the L-shaped sensing head on the temperature sensing vane on the water shortage protection device. The invention further discloses an instant-heating water boiler adopting the water shortage protection device.
