Description

Technical Field

[0001] The utility model relates to the field of instant heating devices, and more specifically, to an electric heating device for an instant heating device. Background Art

[0002] An instant heating device, also called a "quick heating type" or "instant heating type" or "fast heating type" water heater device, is an efficient heating device that converts electrical energy into heat energy to meet the need for rapid heating, and has the characteristics of "turn on and use immediately, no power consumption when not in use", etc. Generally, it requires a relatively high rated power, such as 6KW, 9KW, 12KW, 15KW or even higher.

[0003] For example, in a related technology (see Figure 1 ), a traditional instant heating structure is provided, which is composed of plastic water channel plates arranged on both sides and a plurality of quartz tubes installed on the plastic water channel plates. In this structure, in order to enable the multiple quartz tubes inserted into the water channel plates to communicate with each other, inclined holes need to be opened on both sides of the water channel plates. After the holes are opened, plastic threaded parts are used as plugs to close the holes and divert the water. However, since the water channel plates also undertake the functions of water inlet and outlet, in actual use, as long as the water pressure is too high, there is a possibility that water leaks from the plug holes, resulting in the entire electrical equipment being soaked in water, affecting the service life and the risk of electric leakage. The inclined holes in the water channel plates cause the quartz tubes to be inserted in a vertically offset manner, resulting in slow production, difficult insertion of the electrode copper sheets, and unsmooth water flow. The external threads of the upper and lower water channel fixing bolts are exposed, affecting the aesthetics and practicality of the heating device. Therefore, there is still room for improvement in the instant heating structure in this related technology. Summary of the Utility Model

By using this heating device, not only can smooth water flow be achieved and production efficiency be improved, but also one-time injection molding is realized during use, with good sealing performance to prevent problems such as water leakage and electric leakage.
