[0029] The drinking water heating device of the related art generally controls the water in the drinking water heating device by setting an electromagnetic valve to ensure the stability of the water flow in the drinking water heating device. However, the drinking water heating device of the related art needs to separately set a pipeline structure to connect the electromagnetic valve and the shell, which leads to a complex way of connecting the electromagnetic valve to the shell and is inconvenient for the connection of the electromagnetic valve and the shell.

[0030] Please refer to Figure 1 and Figure 2 The embodiments of the present application provide a drinking water heating device 100 which can be applied to a heating drinking water equipment such as a water purifier to heat the water processed by the heating drinking water equipment for a user to take hot water.

The drinking water heating device 100 does not need to separately set a pipeline to connect the water inlet waterway member 13 and the electromagnetic valve 14, which helps to simplify the structure of the drinking water heating device 100, facilitates manufacturing, and also helps to shorten the flow path of the water. The water does not need to flow through multiple pipelines before entering the heating body 12, which helps to improve the rate of water entering the heating body 12.

[0033] In addition, the water inlet passage 13 can cover the heating body 12, and the water inlet passage 13 and the shell 11 can jointly provide protection for the heating body 12, thereby reducing the exposure damage of the heating body 12.

[0035] In this way, water can enter the heating body 12 through the first loop and be heated, so that the water flowing through the first loop can be heated. The insertion of the first valve body 141 into the first interface 1311 and the insertion of the second valve body 142 into the second interface 1312 help to improve the compactness of the structure of the electromagnetic valve 14 and the water inlet passage 13, simplify the connection mode of the electromagnetic valve 14 to the water inlet passage 13, and facilitate the connection of the electromagnetic valve 14 to the water inlet passage 13.

[0038] For example, the water can flow through the external device such as the charging bin first through the second circuit for preheating, and then the preheated water enters the heating body 12 for heating, so that the water flowing through the second circuit can have a higher temperature. For another example, the water can flow through the external device such as the filtering device first through the second circuit for filtering, and then the filtered water enters the heating body 12 for heating, so as to improve the cleanliness of the water flowing through the second circuit.
