For ease of understanding, the right side in fig. 2 is defined as the front of the cleaning head and the left side is defined as the rear of the cleaning head. As shown in connection with fig. 1-6, the cleaning head of the present disclosure includes a housing 500; the housing is provided with a garbage box 141, a brush assembly 131, a drum 111, a shovel bar 112, a cylindrical squeeze roller 121, a foul water tank 211 and a clean water tank 231 arranged side by side from front to rear, and a water spraying chamber 151 is further provided above the drum at a position close to the squeeze roller. Wherein the brush assembly 131 and the drum 111 are rotatably fixed to the housing. The surface of the brush assembly interferes with the circumferential surface of the drum by about 0.5-1 mm. The shovel bar 112 is in contact with the surface of the object to be cleaned, such as the ground. The squeeze roller 121 presses the drum 111 to squeeze the liquid adsorbed by the drum out, and the liquid flows out from a position below the squeeze roller 121, and in the process of flowing out, the waste attached to the surface of the drum is peeled off and falls into the waste box 141 provided below the squeeze roller 121 together with the liquid. A shovel bar 112 is arranged at the rear lower part of the brush assembly 131, namely at the lower part of the side of the brush assembly close to the roller. The shovel strip 112 is arc-shaped, is made of silica gel material, and is concentrically fixed on the shell with the brush component. The opening of the waste bin faces down brush assembly 131.

The filter box is filled with filter media. The sewage area 2311 is communicated with the sewage tank 211; the water purification area 2312 is communicated with the water spraying cavity 151. The fresh water tank 231 further includes a tank upper cover 2315 which is sealed after being covered thereon.
A cover or a filter screen is arranged on the sewage tank 211 to prevent sewage from sloshing and overflowing in the sewage tank.
The cleaning head also includes a water pump 241 and a motor 242 for driving the water pump. The inlet of the water pump is communicated with the outlet of the water purification area; the outlet of the water pump is communicated with the water spraying cavity.
The bottom surface of the cleaning head shell is provided with the roller, so that the cleaning head can move on the bottom surface conveniently, and the friction force between the roller and the ground is reduced. The center of the rear part of the cleaning head is hinged with a hand-held part for holding an operator. The term "floor" as used in this disclosure is intended to be used in a broad sense and includes any surface to which the present disclosure is applicable.
In operation of the embodiment of fig. 3, the operator pushes the cleaning head forward (to the right) on the floor surface by means of the hand-held portion. The brush assembly 131 rotates clockwise, and the brush assembly 131 and the shovel bar 112 act together to carry granular dry garbage scattered on the ground into the shell, and the dry garbage falls into the garbage box 141 through the upper part of the brush assembly 131. After the brush assembly cleans dry garbage in a granular form, the roller absorbs wet garbage on the ground. When the roller wheel rotates counterclockwise to the squeeze roller 121, the liquid-saturated roller is squeezed, and the liquid therein is squeezed out and flows into the waste water tank 211 along the surface of the sponge mixture. The surface of the brush assembly interferes with the circumferential surface of the drum, and dry trash attached to the surface of the drum can be brushed clean and sent into the trash box 141.
The pressing unit interferes with the drum, and the water thus pressed is present between the pressing unit and the drum, thereby forming a water tank A. The surface of the roller can be cleaned by spraying clean water on the surface of the roller or injecting the clean water into the water tank. For example, a shower chamber 151 may be provided above the water tank a. In this sink position, the surface of the rotating drum is cleaned.
When the cleaning head moves in the reverse direction, the roller cleans wet garbage firstly, and cleans dry garbage after brushing the assembly.
The brush assembly 131 and the drum 111 may be mounted on the housing through bearings and driven simultaneously by the motor 110 through a transmission structure, such as a gear-engaged transmission structure. In other embodiments, the brush assembly and the drum may be driven by two motors, respectively.
The rotation of the brush assembly 131 and the drum 111 may be controlled by a motor.
As an alternative embodiment, the shovel bar of FIG. 3 may be disposed on the housing between the brush assembly 131 and the garbage can 141, such that the brush assembly 131 and the roller 111 may rotate counterclockwise at the same time, the cleaning tool may travel in the left direction of FIG. 3, and the roller may rotate in the same direction as the cleaning tool, so that the cleaning tool may be dragged more easily.
Alternatively, in other embodiments, a one-way mechanism may be provided at the end of the roller, such that the roller can only rotate in one direction by the cooperation of the ratchet and the stop, to prevent the roller from reversing and secondarily contaminating the cleaned floor.
The floor cleaning machine can realize the functions of mopping and sweeping two kinds of floor cleaning simultaneously.
Other variations of the above-described components of the present disclosure are possible and are described in detail below with reference to the accompanying drawings.
FIG. 7 is a schematic structural diagram of an embodiment of the roller. As shown in fig. 7, the roller includes a hard rubber shaft 111c at a shaft center and a sponge layer 111b wrapped and fixed on a circumferential surface of the hard rubber shaft.
The density and hardness of the sponge have a direct influence on the water absorption performance and water storage rate (also called water locking). When the density of the sponge is improved to a certain extent, the water absorption performance is reduced, the hardness is improved, and the water storage rate is improved; on the contrary, the sponge density is reduced, the water absorption is improved, the hardness is reduced, and the water storage rate is reduced.
The roller of this embodiment has only one sponge layer, and the sponge layer 111b is made of polyvinyl alcohol (PVA) foam. The density of the PVA sponge is 0.5-0.25g/cm3Water absorption of 0.5-1.5g/cm3. The Shore A hardness of the PVA sponge is 40-70. The water storage rate of the PVA sponge is 0.2-1.0g/cm3. This sponge layer of this disclosure, because it possesses above-mentioned characteristic, consequently with the ordinary cylinder contrast of current individual layer, has more excellent effect:
the sponge layer has the advantages of being suitable in water absorption performance and water storage rate and suitable in density and hardness, so that when accumulated water on the ground is treated, the sponge layer can absorb more water, and less water is remained on the ground after the ground is dragged.
On the surface of the drum, there may also be provided a spiral protrusion, which may be referred to as a first spiral protrusion 111f, as shown in fig. 7, and which is a single protrusion extending along one end of the drum to the other end, and in other embodiments, there may be provided two spiral protrusions, which have the same pitch and extend from the opposite side of one end of the drum to the other end of the drum. I.e. the starting ends of the two spiral protrusions are located on the same generatrix of the drum. In other embodiments, the arrangement of the two helical projections may also be different: starting from the same generatrix at both ends of the drum, it extends towards the middle in opposite helical directions. The close position of the two spiral bulges, namely the middle part of the roller, is provided with a straight bulge parallel to the axial direction, and the straight bulge is connected with the two spiral bulges.
