Abstract

A fluid assembly includes a housing assembly, a valve assembly and a pump assembly. The housing assembly includes a first side wall portion, a fluid channel portion and a pump cover portion. The fluid assembly has a first valve cavity, an accommodating cavity and a fluid channel communicating with the accommodating cavity. The valve assembly includes a first valve assembly having a first valve core located in the first valve cavity. The pump assembly includes an impeller assembly located in the accommodating cavity. There is spacing between at least part of an axis of the first valve core and an axis of the impeller assembly. In a height direction of the fluid assembly, an end of the impeller assembly close to the first valve core and an end of the first valve core close to the impeller assembly are located at different heights.
