Description

A floor brush module for a cleaning machine and the cleaning machine

technical field

The utility model relates to the field of household cleaning equipment, in particular to a mobile cleaning device, in particular to a floor brush module for a cleaning machine and a cleaning machine.

Background technique

The cleaning machine is a relatively common household portable cleaning device. It first appeared in the form of a vacuum cleaner and can only be used in a dry environment. In order to meet the needs of use in more environments, especially in wet environments, products such as floor scrubbers have been developed. Most of the existing floor washing machines adopt the front roller brush structure. By setting the roller brush on the front side of the casing that can rotate relative to the casing, the area covered by the rotation of the roller brush can be swept and cleaned. However, the cleaning form of the roller brush also has certain disadvantages. The main force of the same type of model to achieve dust collection is the upstream negative pressure source (ie, the fan), which is limited by the horizontal rotation of the roller brush itself. The water spray port is usually fixed. The spray angle cannot be adjusted, which is inconvenient to use.

Of course, there are also some products that are dedicated to making improvements at the spouts to make the water out of the spouts more uniform. For example, the Chinese utility model patent No. CN202122411293.0 discloses "A floor brush seat with water separation function and a floor washing machine with it". The water diversion channel is connected to the spout for spraying the water transferred by the pump body from the spout to the roller brush assembly. Through the setting of the pump body, the water in the water tank is pumped into the water diversion assembly, and the water transferred by the pump body can be quickly sprayed to multiple positions on the roller brush assembly through the setting of the water diversion assembly, which can ensure that every position on the roller brush assembly can be sprayed evenly in a short time, can improve the cleaning efficiency of the floor brush seat, and can also maximize the use of water resources, save water resources, avoid the waste of water resources, and prevent the roller brush assembly from only partially having water, which affects the cleaning efficiency of the floor.

Although the above-mentioned floor washing machine has added a plurality of spouts, the spouts are sprayed towards the rolling brush, which cannot scour the ground, and the position of the spouts cannot be adjusted all the time.
