Background
The floor cleaning machine is a household appliance for cleaning, which can realize the functions of dust collection, floor washing and the like, can be applied to a plurality of occasions such as families, companies, shops and the like, and realizes the fast and efficient floor cleaning work. The floor cleaning machine is generally provided with a water tank and a water spraying part, can wet a cleaning surface, and then cleans the wet cleaning surface through a rolling brush on a floor brush, so as to realize a floor washing function. In the prior art, the water tank is generally arranged on a main machine of the floor cleaning machine, the water spraying component is arranged on the floor brush, the water tank and the floor brush are communicated through an internal water channel pipeline, but a plurality of electrical components are arranged inside the main machine and inside the floor brush, once the water channel pipeline is damaged due to aging or assembly problems, the water leakage situation occurs, and the situation that the electrical components are burnt out easily occurs. On the other hand, when the ground cleaning machine adopts the scheme of external water spraying, the humidity of the ground is influenced by the water spraying angle and the scattering angle to change, the scattering angle of the nozzle determines the wet area of the sprayed water mist on the ground, the water spraying angle is the angle between the water spraying normal line and the gravity line, and the distance of forward water spraying is determined: when the water spraying angle is too small, water can be sprayed onto the rolling brush, so that only part of the rolling brush is wetted, the cleaning effect of the ground is uneven due to different wetting degrees of the rolling brush, and when the water spraying angle is too large, the wet ground area is too far away from the rolling brush, and the dry friction between the rotating rolling brush and the ground easily causes the loss of the rolling brush; on the other hand, when the scattering angle is too little, the water current bunch can too gather, and the ground wet area is little, inefficiency, also leads to the round brush to be only partially soaked simultaneously, and when the scattering angle is too big, spouts the water droplet on ground too dispersed, can not provide sufficient degree of wetness, also influences clean effect equally.
