Description

Scrubbing brush subassembly and surface cleaning equipment

Technical Field

The utility model belongs to the technical field of clean, this disclosure especially relates to a ground brush subassembly and surface cleaning equipment.

Background

Existing floor cleaners clean a floor with a high flow of cleaning liquid in a manner that enables complete wetting of the floor to be cleaned. By wetting the hard floor surface, the cleaning head transfers dust from the floor to the cleaning liquid, which is then removed from the hard floor surface and held in the recovery tank as contaminated cleaning liquid.

Wet surface cleaners generally comprise: a supply tank containing a cleaning solution; a recovery tank for recovering contaminants recovered from the cleaned floor; a motor driven vacuum source to create an evacuated flow path from the floor being cleaned to the recovery tank; a rechargeable battery to provide power to the components; a base station for charging of the wet surface cleaner and post-cleaning maintenance.

Efforts have been made to improve the cleaning function of wet surface cleaning devices to cope with harsh environments.

For example, patent application PCT/CN2022/087954 describes a cleaning device control method and cleaning device having a built-in thermal medium storage chamber for enhancing the cleaning ability of hard stains on a floor by applying a heated cleaning solution to the surface to be cleaned.

However, since the adhesion degree of dirt on the floor surface is different, the cleaning solution of the cleaner for cleaning a hard floor surface in the related art needs a high volume to perform the cleaning treatment of dirt for a predetermined work a plurality of times and to refill the cleaning solution, so that the interruption time of the cleaning work becomes long. Wherein refilling typically comprises filling the solution tank by hand and additionally, in order to further enhance the cleaning effect, a step of mixing with a cleaning agent or a chemical agent to form a cleaning solution is added. Mixing the cleaning solution by hand can be time consuming and can lead to errors in the level detection of the supply tank or the recovery tank.

Claims

1. A floor brush assembly, comprising:

a fluid input;

a roller body portion including at least one first fluid distribution portion;

at least one second fluid distribution portion provided on an outer wall of the drum brush body portion; and

wherein the cleaning liquid input via the fluid input or the foam generated by the foam generating device can be input via the at least one first fluid distribution portion to the at least one second fluid distribution portion, the cleaning liquid and/or foam within the second fluid distribution portion being applied to the cleaning portion.

2. A floor brush assembly according to claim 1, wherein the foam generating means is in communication with the first fluid distribution portion via the fluid input.

3. The floor brush assembly of claim 1, wherein the cleaning liquid input via the fluid input is pumped by a first pump, the foam generating device generating foam based on a mixed liquid formed by the cleaning liquid pumped by the first pump and the cleaning agent pumped by a second pump.

4. The floor brush assembly of claim 3, wherein the first pump body and the second pump body are both disposed on the floor brush assembly.

5. A floor brush assembly according to claim 3 or 4, further comprising a mixer for mixing the cleaning liquid pumped by the first pump and the cleaning agent pumped by the second pump to form the mixed liquid.

6. The floor brush assembly of claim 5, wherein the first pump pumps cleaning liquid to the mixer and the fluid input via different conduits.

7. The floor brush assembly of claim 5, wherein the foam generating device includes a foaming chamber and a foaming assembly positioned within the foaming chamber, the foaming assembly forming foam based on the mixed liquid entering the foaming chamber.

8. The floor brush assembly of claim 5, wherein fluid on-off between the first pump body and the fluid input and fluid on-off between the first pump body and the mixer are controlled based on a solenoid valve assembly.

9. A surface cleaning apparatus, comprising:

a cleaning liquid storage part for storing a cleaning liquid;

a detergent storage part for storing detergent;

a mixer communicating with both the cleaning liquid storage part and the detergent storage part to be capable of mixing the cleaning liquid from the cleaning liquid storage part and the detergent from the detergent storage part to form a mixed liquid; and

the floor brush assembly of any of claims 1-4, which performs a cleaning operation on a surface to be cleaned based on a cleaning liquid provided by the cleaning liquid storage and/or based on foam, wherein the foam is generated based on the mixed liquid.

10. A surface cleaning apparatus, comprising:

a cleaning liquid storage part for storing a cleaning liquid;

a detergent storage part for storing detergent; and

the floor brush assembly of any of claims 5-8, which performs a cleaning operation on a surface to be cleaned based on a cleaning liquid provided by the cleaning liquid storage and/or based on foam, wherein the foam is generated based on a mixed liquid formed by the cleaning liquid and the cleaning agent.
