Problems solved by technology
[0002] In the existing drinking water boilers on the market, the heating control is controlled by the float switch, and the water level float switch will produce scale during long-term use, which will cause the phenomenon of jamming and failure, resulting in the float switch not being able to effectively control the heating work of the water boiler , It is very easy to cause the water boiler not to work or dry without water, which will affect the normal use of the water boiler. In serious cases, it will burn out the equipment, and even cause serious consequences such as fire.

The invention discloses a water boiler heating protective device which is composed of a floating ball, a transmission connecting rod, an upper microswitch and a lower microswitch. The lower end of the transmission connecting rod is connected with the floating ball. The upper end of the transmission connecting rod is movably fixed to the body of a water boiler through a rotating shaft. The upper microswitch is arranged above an upper transmission rod. The lower microswitch is arranged below the upper transmission rod. The upper microswitch and the lower microswitch are electrically connected with a relay in a water boiler water level control circuit through wires respectively. By the adoption of the technical scheme, the water boiler heating protective device overcomes defects in the prior art, is simple in structure, safe and reliable, effectively prevents inoperation or water-free heating phenomena of the water boiler, and ensures using safety of equipment.
Description
technical field [0001] The invention relates to a drinking water boiler, in particular to a heating protection device for a water boiler. Background technique [0002] In the existing drinking water boilers on the market, the heating control is controlled by the float switch, and the water level float switch will produce scale during long-term use, which will cause the phenomenon of jamming and failure, resulting in the float switch not being able to effectively control the heating work of the water boiler , It is very easy to cause the water boiler not to work or dry without water, which will affect the normal use of the water boiler. In severe cases, the equipment will be burned out, and even serious consequences such as fire will occur. Contents of the invention [0003] The object of the present invention is to provide a heating protection device for a water boiler, which overcomes the deficiencies of the prior art, has a simple structure, is safe and reliable, effecti...
