[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A ceramic heating element, used in an electric water heater, includes a ceramic heating element and a sleeve. The ceramic heating element comprises a base, a headstock, a grooved tube, and a heating wire. Several grooved tubes are spliced ​​between the base and the headstock. Each grooved tube has multiple axial channels. The heating wire meanders through the axial channels of the grooved tubes. Bolts connect the base, grooved tubes, and headstock into a single structure. The sleeve has a flange with screw posts on it. A heating element fixing bracket is fitted onto the screw posts, allowing the ceramic heating element to be mounted on the sleeve.

[0006] The outer surface of the sleeve has an enamel layer.

[0007] The heating element fixing bracket includes a mounting part and a baffle. The mounting part is fitted onto the screw post and tightened with a nut. The ceramic heating element is inserted into the tube sleeve. The baffle extends toward the head seat to prevent the ceramic heating element from falling out of the tube sleeve.

[0008] The headstock is provided with a groove, and the baffle extends into the groove.

[0009] The sleeve includes an electric heating sleeve and a temperature measuring tube, both of which are welded to the flange.

[0010] The magnesium rod support is connected to the heating tube sleeve and / or temperature measuring tube, and the magnesium rod is installed on the magnesium rod support.

[0011] The magnesium rod support is vertically welded to the heating tube sleeve and the temperature measuring tube.

[0012] An electric water heater includes a shell, an inner tank, and the aforementioned ceramic heating element.

[0013] The above technical solution has the following beneficial effects:

[0014] The present invention relates to an enamel-coated ceramic heating element and its water heater. The split-type heating element makes it easy to replace, and the enamel-coated sleeve increases its corrosion and scale resistance. Attached Figure Description

[0023] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] See Figures 1-6As shown, this utility model discloses a ceramic heating element and a water heater using the ceramic heating element. The water heater consists of an outer shell 1 and an inner tank 2. An insulation layer 3 is provided between the outer shell 1 and the inner tank 2 to prevent heat loss from the water inside the water heater. A sleeve 4 is installed on the inner tank 2, and a ceramic heating element 5 is installed on the sleeve 4. The ceramic heating element 5 is heated by a temperature controller 9 installed on the water heater, so that the water inside the water heater is heated to the set temperature. In addition, a thermometer is installed on the outside of the water heater for the user to observe the water temperature. Figure 2 In the diagram, number 7 indicates the water inlet of the water heater; number 8 indicates the water outlet of the water heater.

[0025] The sleeve 4 is formed by welding the electric heating tube sleeve 402 and the temperature measuring tube 403 onto the flange 401. The flange 401 is welded with screw posts 405 for fixing the ceramic electric heating tube 5. The magnesium rod bracket 404 is welded to the electric heating tube sleeve 402 and the temperature measuring tube 403 to improve strength and to assemble the anode magnesium rod 12.
