Description

Mixer for fluids Technical Field Embodiments of the present disclosure relate generally to the field of spray jet printing technology, and more particularly to a mixer for fluids. Background Before spray printing on a target object (e.g., a fabric), a corresponding liquid to be sprayed, such as ink configured to have a specific color or a specific component ratio, needs to be disposed. The configuration process requires, for example, mixing of inks of different compositions (or different colors). In the conventional mixing method, the mixing is not uniform. If the mixture is not uniform, the color of the spray is often uneven, and the spray effect is affected. Disclosure of Invention In view of the above, the present disclosure provides a mixer for fluids that can thoroughly mix the fluids being mixed, thereby facilitating the formation of a well-mixed fluid. According to one aspect of the present disclosure, a mixer for fluids is provided. The mixer includes a first conduit defining a first receiving cavity, a first fluid inlet in communication with the first receiving cavity for the first fluid to enter the first receiving cavity via the first fluid inlet, a second conduit defining a second receiving cavity, at least a portion of the second conduit extending into the interior of the first receiving cavity, the at least a portion of the second conduit including a fluid output portion including a plurality of first through holes in communication with the second receiving cavity and the first receiving cavity for the second fluid in the second receiving cavity to enter the first receiving cavity for mixing with the first fluid, a second fluid inlet in communication with the second receiving cavity for the second fluid to enter the second receiving cavity via the second fluid inlet, a fluid outlet in communication with the first receiving cavity for the mixed fluid output, and a drive unit configured to drive the second conduit to rotate relative to the first conduit.
