It is to be understood that these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of these exemplary embodiments to those skilled in the art.

In particular, the cleaning device may include a sweeper, scrubber, sweeping all-in-one machine, or the like.

Further, the cleaning apparatus includes a machine body and a cleaning system including a cleaning assembly 130 and a cleaning assembly lifting device. The cleaning assembly 130 is located below the machine body and enables a cleaning process of the surface to be cleaned. It will be appreciated that the cleaning assembly 130 may be a dry cleaning assembly, for example, the cleaning assembly 130 may include a main brush, a mounting bracket 131, etc., the main brush being mounted on the mounting bracket 131, the main brush having a certain interference with the floor to sweep up and roll up the garbage on the floor in front of the dust suction opening between the main brush and the dust box, and then being sucked into the dust box by the suction air generated by the fan and passing through the dust box, so as to achieve dry cleaning. Alternatively, the cleaning assembly 130 may be a wet cleaning system, for example, the cleaning assembly 130 may include a roll/mop mounted on the mounting bracket 131, a water supply system for supplying water to the roll or mop to wet the roll or mop, or a water supply system for spraying water to the floor to be cleaned, the roll or mop having some interference with the floor being capable of wiping off stains on the floor to achieve wet cleaning.

The related art cleaning assembly is either separated from the floor surface or is applied with a fixed pressure to be in contact with the floor surface to achieve cleaning of the floor surface, wherein the pressure applied to the cleaning assembly to be in contact with the floor surface may be referred to as a down pressure. The existing cleaning equipment can pressurize a cleaning assembly by means of dead weight or a spring, a counter weight and the like, and because pressurization is generally fixed, different environmental grounds such as humidity, temperature, ground material, ground form and the like have different friction coefficients, the fixed downward pressure has the problems of larger downward pressure or smaller downward pressure and the like for different environmental grounds, wherein when the downward pressure is higher, the walking resistance of the cleaning equipment can be increased, and the cleaning equipment is easy to slip and cannot walk; when the lower pressure is lower, the cleaning effect of the floor is affected.

In view of this, as shown in fig. 1 and 2, an embodiment of the present invention provides a cleaning assembly lifting device, including: the cleaning device comprises a driving part 110, a lifting mechanism 120 and an elastic part 140, wherein the elastic part 140 is arranged between the lifting mechanism 120 and the cleaning assembly 130, the driving part 110 is connected with the lifting mechanism 120, and the driving part 110 drives the lifting mechanism 120 to work so as to adjust the deformation of the elastic part 140 and further adjust the downward pressure of the cleaning assembly 130.

That is to say, the lifting mechanism 120 is driven to operate by the driving portion 110, the deformation amount of the elastic member 140 can be adjusted, the elastic member 140 is located between the lifting mechanism and the cleaning assembly 130, and then the pressure of the elastic member 140 acting on the cleaning assembly 130 can be adjusted, and then the downward pressure of the cleaning assembly 130 can be adjusted, if the pressure of the cleaning member acting on the surface to be cleaned can be adjusted, that is, the downward pressure of the cleaning assembly 130 on the ground can be dynamically adjusted by the lifting device of the cleaning assembly, so that the downward pressure of the cleaning assembly 130 can meet the requirements of friction coefficients of the grounds in different environments, so that under the condition that the cleaning device can normally operate, a good cleaning effect is ensured, and the use range of the device is expanded.

For example, when the cleaning device is in operation, the detection device, such as an odometer (odometer), detects that the cleaning device slips, which indicates that the downward pressure of the cleaning assembly 130 is large to some extent, so that the control device controls the driving portion 110 to operate according to the detection signal of the detection device, and reduces the deformation amount of the elastic member 140 through the lifting mechanism 120, so that the downward pressure of the cleaning assembly 130 on the floor is reduced, thereby suppressing the slip and ensuring the normal operation of the cleaning device. When the cleaning device is in operation, the detection device detects that the current of the wheels of the cleaning device is relatively small or the walking resistance is relatively small, which indicates to some extent that the current problem of unsatisfactory cleaning effect is caused by relatively small downward pressure of the cleaning assembly 130, therefore, the control device controls the driving part 110 to work according to the detection signal of the detection device, and the deformation of the elastic member 140 is increased through the lifting mechanism 120, so that the downward pressure of the cleaning assembly 130 on the ground is increased, and further the cleaning effect is improved under the condition of ensuring that the cleaning device can normally operate.

The pressing plate 122 is located above the cleaning assembly 130, and the elastic member 140 is disposed between the pressing plate 122 and the cleaning assembly 130, so that when the screw 121 is driven by the driving part 110 to rotate in one direction, the pressing plate 122 can move downward along the screw 121, that is, the pressing plate 122 and the screw 121 are matched, the rotation motion of the screw 121 can be converted into the linear motion of the pressing plate 122, the elastic member 140 is compressed by the pressing plate 122, and the pressing force of the cleaning assembly 130 can be increased when the cleaning member contacts with the surface to be cleaned under the action of the elastic member 140. When the screw 121 is rotated in the other direction by the driving part 110, the pressing plate 122 can move upward along the screw 121, and the pressure of the cleaning assembly 130 contacting the floor can be relieved while the elastic member 140 is deformed again, thereby reducing the downward pressure of the cleaning assembly 130.

Wherein, in the rotation process of the driving portion 110 driving screw 121, the pressing plate 122 can move up and down along the screw 121, because the guide pillar 124 penetrates through the pressing plate 122, the pressing plate 122 can slide along the guide pillar 124 in the process of moving along the screw 121, the arrangement of the guide pillar 124 is beneficial to improving the stability and accuracy of the movement of the pressing plate 122, and further the stability of the movement of the cleaning component 130 can be ensured, the downward pressure of the cleaning component and the part in contact with the ground is balanced, and further a good cleaning effect is ensured.

Further, the position of the pressing plate 122 on the guide post is limited by the limiting member 123, for example, by reasonably setting the deformation amount of the elastic member 140, when the driving portion 110 drives the screw rod 121 to rotate to drive the pressing plate 122 to ascend relative to the screw rod 121, when the compression amount of the elastic member 140 is reduced to zero, that is, the elastic member 140 is reset to a free state, and the acting force of the elastic member 140 on the cleaning assembly 130 may be zero, the cleaning member of the cleaning assembly 130 can be separated from the ground, so as to meet the working requirement that the cleaning member does not need to contact with the ground.
