By separating the first chamber, which is mainly used for heating, from the second chamber, which is mainly used for draining, the volume of the second chamber can be independently adjusted according to the required lift and flow, so that the power of the power part can be effectively reduced, and the aim of saving the cost is fulfilled. Also, by extending at least a portion of the connecting member into the first chamber, a degree of disturbance of the water flow entering the first chamber can be provided, thereby creating a relatively complex flow path.

It will be appreciated that, similarly to the separate adjustment of the volume of the second chamber, the volume of the first chamber may also be adjusted separately according to the actual situation. In addition, since the first chamber is mainly used for heating, and the heating member is usually a component which is continuously in a static state, unlike the first chamber, the structure and the volume of the second chamber are not limited by, for example, the power unit, and therefore, in addition to the volume adjustment, other specifications such as the structure, for example, a prismatic tube, a tube composed of a plurality of segments of prisms, an irregular structure of all or a part of the tube, a solid structure of a part of the tube, and the like can be adjusted according to actual conditions.
