Abstract
The present disclosure discloses a foaming spraying device and a foaming toilet. The foaming spraying device comprises a foaming spraying body. The foaming spraying body comprises a foaming cavity, a suction port, an accelerating hole, and a foam spraying port, each of which is in communication with a foaming cavity. The accelerating hole is configured to enable a foaming solution to be accelerated to enter the foaming cavity of the foaming spraying body, so that the foaming cavity of the foaming spraying body generates negative pressure to suck air through the suction port and the air is mixed with the foaming solution to form foam.
