The detailed description of the technical contents, structural features, and the objects and effects of the present invention will be described in detail below with reference to the embodiments.

Referring to FIG. 1 , the utility model relates to a water-cut water tank, which comprises a right casing 1 , a left casing 2 and a heating element 3 , and a heating element 3 is arranged between the right casing 1 and the left casing 2 . In order to ensure a good sealing connection between the left housing 2 and the right housing 1, a sealing groove is provided on the inner walls of the left housing 2 and the right housing 1, and a sealing port 4 is provided in the sealing groove.

The left casing 2 and the inner wall of the right casing 1 are separated by a plurality of mutually parallel spacers 203 to form a water flow passage 206, and the spacer 203 is not closed on the left casing 2 or the right casing 1 ( Or the spacer 203 is provided with a water passing hole 205), and the unsealed end or the water passing hole 205 of the adjacent spacer 203 is disposed at a dislocation interval, thereby the inner walls of the left housing 2 and the right housing 1 at both ends That is, the water flow channel separating the zigzag S-shaped loop can effectively increase the flow distance after the water flow enters, and ensure that it is fully heated. On the left casing 2 (which may also be the right casing 1), a water inlet 201 and a water outlet 202 connecting the left casing 2 and the right casing 1 water flow passage 206 are provided, which are different from the common water passage of the tubular circuit. In the patent, the spacer 203 is changed in shape, that is, the spacer 203 is provided with the highest position relative to the rest of the spacer 203, and the highest point of the plurality of spacers 203 is disposed opposite to the water outlet 202, that is, The highest point of the spacer 203 is on the same line as the water outlet, or approximately on the same straight line, thereby effectively ensuring that the product will be squeezed by the remaining water in the event that the heated water in the water flow channel 206 forms water vapor during use.
