Mouthpiece assembly and washlet

Abstract

The application discloses a suction nozzle assembly and a washing and sweeping machine. The suction nozzle assembly comprises a suction nozzle body, a baffle and a water suction box. The suction nozzle body comprises a top plate and a surrounding plate. The top plate is provided with a suction port. The surrounding plate is connected with the top plate and extends along the left-right direction. The baffle is connected with the suction nozzle body and is opposite to the surrounding plate in front and back. The surrounding plate and the baffle form a negative pressure cavity which is communicated with the suction port. The bottom of the negative pressure cavity is open and the top is covered by the top plate. The water suction box is arranged at at least one end of the negative pressure cavity along the left-right direction and is provided with a water suction cavity which is communicated with the negative pressure cavity. The lower side and the side close to the negative pressure cavity of the water suction cavity are open. The depth dimension of at least a part of the water suction cavity along the up-down direction is less than or equal to the depth dimension of the negative pressure cavity. According to the suction nozzle assembly in the embodiment of the application, the air inlet amount of the left and right ends of the negative pressure cavity can be increased to compensate for the problem of insufficient air speed due to the distance from the suction port. The water flow at the position can be brought to the suction port to be smoothly discharged, and the phenomenon of water spitting of the suction nozzle assembly can be avoided.
