Description

Ceramic heater for heating water Technical Field The utility model belongs to the technical field of ceramic heaters, and relates to a ceramic heater for heating water. Background The conventional water heating device mainly adopts a metal heating pipe as a heat source, and the conventional design has the problems of uneven heat distribution, local overheating, low energy efficiency and the like in the heating process although the conventional design is widely applied, meanwhile, the metal material is easy to corrode after long-term use in water, the service life of equipment is further reduced, and potential safety hazards such as electric leakage and electric shock are hidden due to the fact that the metal is in direct contact with the water. The patent of China patent publication No. CN203880914U discloses a quick heater, including the heater casing the heating element that sets up in the heater casing, the heating element is including supplying the heating pipe that is heated the medium and pass through the heating pipe outside parcel has the insulating film outside cover is equipped with ceramic protection tube the insulating film with be provided with the heat-generating body between the ceramic protection tube the heating pipe both ends are connected with water outlet connection and water inlet connection respectively, and this technical scheme is through the cover at the heat-generating body outside establish ceramic protection tube and insulating, even can not cause the circumstances emergence of ceramic protection tube fracture leakage when the heat-generating body has little deformation to the ceramic protection tube can effectively bear the high temperature that the heat-generating body produced in the use, but this technical scheme is limited with the area of contact of rivers, probably can lead to the problem that the heating efficiency is low. Disclosure of utility model The utility model provides the ceramic heater for heating water, which solves the problems in the prior art well. In order to achieve the purpose, the ceramic heater for heating water comprises a cylindrical outer shell and an inner shell, wherein tungsten slurry heating circuits are arranged on opposite sides of the outer shell and the inner shell, two groups of power-on assemblies which are respectively connected with two ends of the tungsten slurry heating circuits are arranged on the outer side face of the outer shell, spiral bulges are arranged on the inner side face of the inner shell, and a plurality of hemispherical bulges are arranged on the upper side face and the lower side face of each spiral bulge. Further, the power-on assembly comprises an electrode plate arranged in the outer shell, a power-on wire arranged on the outer side face of the electrode plate and a wiring terminal arranged at one end, far away from the electrode plate, of the power-on wire, and the electrode plate is in contact with the end part of the tungsten paste heating circuit.
