Conical cavity mixer

The utility model relates to a mixer with a conical cavity. The technical problem that an existing mixer is low in mixing efficiency when flow is too large is solved. Comprising a mixer body, an upper seat is installed at the upper end of the mixer body, a lower seat is installed at the lower end of the mixer body, a plurality of mixing units are sequentially arranged in the mixer body, each mixing unit is provided with at least one conical mixing cavity, and the mixing cavities are sequentially communicated through a plurality of transversely-arranged flow channels. The flow channels are formed between the mixer body and the upper base and between the mixer body and the lower base, one of the two mixing units located on the two outermost sides in the mixer body is communicated with the liquid inlet through the flow channel, and the remaining mixing unit is communicated with the liquid outlet through the flow channel. The device has the advantage that the mixing effect can be ensured through the plurality of
