Referring to fig. 2 and 3, the floor brush assembly 1 includes a body 10, a roller brush 20, a driving member (not shown), and a heating member 30. The body 10 has a brush chamber 11, the roller brush 20 is disposed in the brush chamber 11, the driving member is coupled to the body 10 and drives the roller brush 20 to rotate relative to the body 10 so that the floor brush assembly 1 can perform a cleaning operation, and the heating member 30 is coupled to the roller brush 20 and configured to provide heat energy to the roller brush 20.

Alternatively, the driving member may be a servo motor, a motor, etc., and the heating member 30 may be a heating wire, an electrothermal film, a PTC heating element, etc.

In actual operation, the clean water tank supplies water to the rolling brush 20, and the rolling brush 20 rotates relative to the body 10 under the action of the driving piece and cleans the surface to be cleaned. Meanwhile, the suction assembly recovers the sewage cleaned by the rolling brush 20 to the sewage tank to ensure a better cleaning effect. When scrubbing brush subassembly 1 carries out cleaning operation and/or carry out cleaning operation after, heating member 30 provides heat energy for round brush 20, and makes round brush 20 can be dried after carrying out cleaning operation, like this, can prevent that round brush 20 from breeding the bacterium and smelly even, has better user experience degree.

Preferably, the heating member 30 continuously supplies the heat energy to the roll brush 20 while the floor brush assembly 1 performs the cleaning operation and for a period of time after performing the cleaning operation. In the process of performing the cleaning operation, the heat energy provided by the heating member 30 can raise the temperature of the water body in the roller brush 20 to soften the stain on the surface to be cleaned, so that the floor brush assembly 1 has a better cleaning effect. After the cleaning operation is finished, the heat energy provided by the heating member 30 can accelerate the evaporation speed of the water on the roller brush 20 until the brush body 22 is dried. Therefore, the rolling brush 20 can be prevented from breeding bacteria and even smelling, and better user experience is achieved.

In one embodiment, the rolling brush 20 includes a shaft 21 and a brush 22 sleeved outside the shaft 21, the shaft 21 contacts the driving member, and the brush 22 is driven by the driving member to rotate, so as to perform a cleaning operation. The heating member 30 is coupled to the shaft 21 and provides heat energy to the brush 22 through the shaft 21. That is, the heating member 30 indirectly supplies power to the brush body 22 via the shaft body 21.

The shaft 21 serves to support the brush 22, and the shaft 21 is generally made of a rigid waterproof material having excellent mechanical strength. For cleaning, the brush body 22 is generally made of a flexible material with excellent water absorption property, such as water absorption flannelette.

If the heating member 30 directly contacts the brush body 22 and supplies power to the brush body 22, the difficulty of mounting the heating member 30 is increased because the brush body 22 may be deformed by being pressed against the surface to be cleaned during operation. In the present application, the heating member 30 is coupled to the shaft 21, and the shaft 21 has a better rigidity strength, so that the heating member 30 can be better supported, and the assembly difficulty of the heating member 30 can be reduced.

In one embodiment, the shaft 21 has a heat conducting cavity 211 therein, and the heating member 30 is disposed in the heat conducting cavity 211. In the floor brush assembly 1, the shaft 21 blocks the heating member 30 from the brush body 22, so that the water on the brush body 22 is prevented from contacting the heating member 30 to cause electric leakage, thereby having high safety in use.

Referring to fig. 2 and fig. 3 again, the shaft body 21 includes a shaft tube 215, a first end cap 213 and a second end cap 214, the shaft tube 215 is a hollow structure with two open ends, and the first end cap 213 and the second end cap 214 are respectively covered on two opposite openings of the shaft tube 215 and surround the shaft tube 215 to form the heat conducting cavity 211. The heating member 30 can be easily disassembled by disassembling either one of the first end cap 213 and the second end cap 214.

Preferably, the heating member 30 has an elongated shape and extends in the axial direction of the shaft 21. In this way, the heating member 30 can uniformly transfer heat to the brush body 22 through the shaft cylinder 215 in the axial direction of the shaft body 21, so as to finally achieve rapid drying of the brush body 22.

Furthermore, the shaft 21 is provided with a heat dissipation hole 212 communicating with the heat conduction cavity 211, and the brush 22 is disposed outside the heat dissipation hole 212. In the process of the operation of the heating member 30, the heat released from the heating member 30 can be rapidly diffused to the brush body 22 through the heat dissipation holes 212 and heats the brush body 22, so that the drying efficiency of the brush body 22 can be improved.

Preferably, the heat dissipation holes 212 are opened on the shaft cylinder 215 and extend along the axial direction of the shaft 21, and the heating element 30 covers the heat dissipation holes 212. With such a design, the heat generated by the heating element 30 can be rapidly transmitted to the brush body 22 through the heat dissipation hole 212, thereby improving the drying efficiency and cleaning effect of the floor brush assembly 1.

The brush 22 includes a brush portion (not shown) and a waterproof portion (not shown), the brush portion is disposed outside the shaft 21, and the waterproof portion is coupled to an inner surface of the brush portion facing the shaft 21 and covers the heat dissipation hole 212. In such a roller brush 20, the water on the brush body 22 is blocked outside the heat conduction cavity 211, so as to prevent the water on the brush body 22 from flowing into the heat conduction cavity 211 and contacting with the heating element 30 to cause electric leakage, thereby improving the safety of the operation of the floor brush assembly 1.

Preferably, the waterproof portion completely covers the outer circumferential surface of the shaft body 21. With this design, even if the brush 22 and the shaft 21 are mounted in a misaligned state, the waterproof section can be continuously ensured to cover the heat radiation hole 212 at all times.

Further, the waterproof portion may be a glue layer, and the brush portion is adhered to the shaft 21 through the glue layer.

Specifically, one end of the supporting shaft 40 is connected to the body 10, the other end of the supporting shaft 40 penetrates through the first end cap 213 of the shaft body 21 along the axial direction of the shaft body 21, and the rotating shaft of the driving member penetrates through the second end cap 214 along the axial direction of the shaft body 21. In operation, the main body 10, the power supply unit and the supporting shaft 40 are relatively kept stationary, the driving unit drives the second end cap 214 to drive the shaft cylinder 215, the first end cap 213 and the conductive unit 50 to rotate relative to the supporting shaft 40, and further, the brush 22 rotates to clean the surface to be cleaned.

The power supply member, the support shaft 40, the conductive member 50, and the heating member 30 are provided to supply power to the heating member 30 without an external power source. Therefore, the cleaning device and the floor brush assembly 1 thereof have better cleaning flexibility.
