[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0025] Embodiment 1

[0026] In order to solve the problem that the brush disc is easily damaged by collision when cleaning the ground, please refer to Figs. 1-3 The washing machine provided in the embodiment can change the position of the brush disc when the brush disc collides, buffer the force of the collision, and reduce the risk of deformation, fracture or wear of the brush disc due to the collision. The washing machine comprises a support 1 having an inner cavity, the support 1 is fixedly installed on the washing machine, and the support 1 serves as a carrier for supporting a buffer assembly 2 and a lifting assembly 3. The support 1 is provided with the buffer assembly 2 for reducing the collision, and the support 1 is provided with the lifting assembly 3 for driving the buffer assembly 2 to slide vertically. When producing the washing machine, the support 1 is installed on the washing machine in advance. When using the washing machine, the buffer assembly 2 is lifted by the lifting assembly 3, and then the appropriate brush disc is installed according to the requirement. When the brush disc collides during the use of the washing machine, the position of the brush disc is changed, the force of the collision is buffered, the impact force generated by the collision is absorbed, and the risk of deformation, fracture or wear of the brush disc due to the collision is reduced. The service life of the brush disc is prolonged, the frequency of replacing the brush disc is reduced, and the equipment maintenance cost is reduced.

[0027] The brush disc is easy to collide with the ground or surrounding obstacles when cleaning the ground, which may cause deformation and damage of the brush disc, resulting in poor cleaning effect. Therefore, it is necessary to reduce the impact on the brush disc when the brush disc collides to reduce the damage. The buffer assembly 2 comprises a support plate 21 slidably installed in the bracket 1, and the support plate 21 is used to connect with the connecting plate 22. One end of the support plate 21 extends out of the inner cavity of the bracket 1, and a connecting plate 22 for connecting the brush disc is detachably installed on the support plate 21. The connecting plate 22 is used to connect and support the brush disc, and the connecting plate 22 is integrally formed to increase its rigidity and firmness. The end of the support plate 21 is provided with a sliding surface 211, and the angle of the sliding surface 211 is 120-140 degrees. The connecting plate 22 is provided with a groove 221, and the width and length of the groove 221 are greater than those of the sliding surface 211. The collision is reduced when the connecting plate 22 slides, and the rotation is not blocked. The support plate 21 is provided with a circular arc-shaped sliding groove 212, and the sliding groove 212 limits the movement path of the screw rod 213. The angle of the sliding groove 212 is the same as that of the sliding surface 211, and the length of the sliding groove 212 is greater than the extension length of the torsion spring 26, so that the position of the brush disc can be adjusted completely when the collision occurs. The connecting plate 22 in the groove 221 is fixedly installed with a screw rod 213 sliding in the sliding groove 212, and the screw rod 213 is threadedly connected with a nut 214. The screw rod 213 and the nut 214 are used to connect the support plate 21 and the connecting plate 22, so that the connecting plate 22 can be conveniently connected, installed and detached. The length of the screw rod 213 is greater than the height of the sliding groove 212, and the width of the nut 214 is greater than the width of the sliding groove 212 and located on the surface of the sliding groove 212, so that the support plate 21 and the connecting plate 22 can be connected. A plurality of fixing holes 23 for fixing the brush disc are symmetrically arranged on the connecting plate 22, and the fixing holes 23 facilitate the connection of different brush discs. The support plate 21 is fixedly connected with symmetrically arranged mounting rods 24, and the connecting plate 22 is fixedly connected with symmetrically arranged connecting rods 25. The mounting rods 24 and the connecting rods 25 are fixedly connected with a torsion spring 26, and the torsion spring 26 is used to limit the movement state of the connecting plate 22. When the brush disc is installed, the connecting plate 22 can be removed in advance, and then the brush disc is installed on the connecting plate 22. Then, the screw rod 213 on the connecting plate 22 is aligned and inserted into the sliding groove 212, and the nut 214 is installed on the screw rod 213 to fix the connecting plate 22. When the brush disc is installed, if the brush disc collides during cleaning, the brush disc and the connecting plate 22 are subjected to the elastic force of the torsion spring 26, so that the connecting plate 22 changes its position in the movement path of the sliding groove 212, so that the collision force is buffered and absorbed in the process of changing the position, thereby reducing the impact of the collision force on the brush disc, reducing the risk of deformation, fracture or wear due to collision. The service life of the brush disc is prolonged, the frequency of replacing the brush disc is reduced, and the equipment maintenance cost is reduced. Moreover, the brush disc can still maintain stable contact with the ground as much as possible after collision.Avoiding the brush disc from being lifted or deviated instantaneously due to collision, thus ensuring the continuity and stability of the cleaning process, and improving the cleaning effect.

[0028] Considering that the screw rod 213 and the nut 214 easily cause large wear when sliding for a long time, the connecting plate 22 is likely to fall off the support plate 21 during use, which is likely to cause damage to the brush disc, therefore, it is necessary to reduce the friction during sliding, referring to Figs. 1-3 A plurality of mounting grooves 215 are arranged on the support plate 21 and located on both sides of the sliding groove 212, the mounting grooves 215 are arranged at an angle along the sliding groove 212, and a mounting plate 216 is slidingly mounted in the mounting grooves 215, the mounting plate 216 is used to support the ball 217. The ball 217 is rotatably mounted in the mounting plate 216, and the surface of the ball 217 is smooth. The ball 217 is located below the nut 214, and the end portion slightly exceeds the surface of the mounting groove 215. The second spring 218 is fixedly connected between the mounting plate 216 and the inner wall bottom end of the mounting groove 215, and the second spring 218 is used to limit the active state of the mounting plate 216. When the nut 214 is connected with the screw rod 213, the nut 214 applies force to the ball 217, and under the conduction of the force, the second spring 218 is driven to slightly retract, so that the nut 214 is not affected when it is fixed to the connecting plate 22. Then, under the action of the ball 217, the sliding state between the nut 214 and the sliding groove 212 is changed to a rolling state when the screw rod 213 drives the nut 214 to slide, reducing the contact area between the two, reducing the friction resistance, reducing the friction between the nut 214 and the support plate 21, and further reducing the damage caused by friction, thereby improving the service life.

[0029] Considering that the connecting plate 22 is easily scratched and damaged after collision, and the wear and tear and the appearance are easily aggravated after long-term use, it is necessary to reduce the damage caused by collision, referring to Figs. 1-3 The width of the connecting plate 22 is greater than that of the support plate 21, which can firmly support the brush disc and reduce the influence of the fixing area on the fixing effect. The rubber sleeve 27 is sleeved on the surface of the connecting plate 22 except the groove 221, which reduces the friction between the groove 221 and the support plate 21. When a collision occurs, the impact force is buffered and absorbed by the material of the rubber sleeve 27, and the connecting plate 22 may also collide with other obstacles when the position changes, and the rubber sleeve 27 can directly reduce the damage caused by the collision of the connecting plate 22, and will not leave scratches and other damage on the surface, thereby improving the service life of the connecting plate 22, and improving the appearance and aesthetic degree.

[0030] Embodiment 2

[0031] On the basis of the embodiment 1, considering that the brush disc needs to be replaced according to the actual situation in the actual use of the ground, and the brush disc is inconvenient to disassemble and assemble due to the low position when disassembling and assembling the brush disc, the disassembly and assembly height needs to be adjusted to facilitate the disassembly and assembly of the brush disc. Figs. 1-3 The lifting assembly 3 comprises a sliding shaft 31 fixedly installed in the inner wall of the inner cavity of the support 1 and penetrating the support plate 21, the support plate 21 is slidingly installed on the sliding shaft 31, and the first spring 32 is fixedly connected between the top end of the inner wall of the inner cavity of the support 1 and the support plate 21, and the first spring 32 is used for limiting the active state of the support plate 21. The sliding shaft 31 is sleeved in the first spring 32, the support 1 is fixedly installed with the electric push rod 33 for driving the support plate 21 to slide, and the electric push rod 33 serves as a power source for lifting. The movable end of the electric push rod 33 is rotatably installed on the support plate 21. When the brush disc needs to be disassembled and assembled during use, the electric push rod 33 is started, and the support plate 21 is vertically slid under the limitation of the first spring 32 and the sliding shaft 31 under the driving of the movable end of the electric push rod 33, so that the support plate 21 can adjust the height during sliding, and then the height can be adjusted to be more appropriate during disassembly and assembly of the brush disc, and the brush disc can be conveniently disassembled and assembled without the need for professional technicians to perform complex operations in the simple and convenient installation mode, thereby reducing the time wasted due to equipment downtime and improving work efficiency.
