The invention discloses a dry-heating preventive device of a liquid heater. The dry-heating preventive device comprises a shell. A cavity is arranged inside the shell, a water inlet and a water outlet which are communicated with the cavity are arranged on the shell, a reed is arranged on the top of the cavity, a floating ball which can move along the reed up and down is sleeved on the outside of the reed, and magnets are arranged inside the floating ball. The dry-heating preventive device has the advantages that the dry-heating preventive device is mainly applied to liquid heating devices such as instant water heaters, and is mounted on a liquid delivery pipeline at the front of the heater, water flow flows through the dry-heating preventive device before flowing into the heater, the floating ball floats when the water flow flows through the dry-heating preventive device, and the heater can work normally; the floating ball descends when in water deficiency, and the reed outputs a control signal, so that the heater stops working, dry-heating of the heater is prevented, and the heater is effectively protected.
Description
technical field [0001] The invention relates to an anti-skid burning device, in particular to an anti-skid burning device for a liquid heater. Background technique [0002] Existing instant water heaters use combustion to heat the flowing water to increase its temperature, but such instant water heaters may appear empty burning phenomenon, which seriously affects the performance and service life of the water heater, and exists safety hazard. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the purpose of the present invention is to provide a liquid heater anti-running device, which can effectively prevent the dry burning phenomenon of liquid heaters such as water heaters. [0004] The technical scheme adopted in the present invention is mainly: [0005] An anti-empty burning device for a liquid heater, comprising a housing with a cavity inside, the housing is provided with a water inlet and a water outlet communicating with the...
