The cleaning apparatus and the cleaning robot of the present invention will be described with reference to fig. 1 to 7.

According to an embodiment of the first aspect of the present invention, referring to fig. 1 to 7, the cleaning apparatus provided by the present invention mainly includes: the scraper component comprises a bracket 1, two groups of scraper components 2 and a driving component. Wherein, two sets of scraper blade subassemblies 2 are fixed in the relative both sides of support 1 respectively, and drive assembly mainly used drives whole support 1 swing to drive two sets of scraper blade subassemblies 2 and carry out corresponding swing.

The drive assembly includes: driving motor 3 with pull the mechanism, pull the mechanism and include: the rotary pull seat 4 and the two first elastic pieces 5 are arranged on the support, the driving motor 3 is in transmission connection with the rotary pull seat 4, the driving motor 3 and the rotary pull seat 4 can be specifically arranged above the support 1, and the driving motor 3 can be a speed reducing motor or other types of motors; the two first elastic members 5 are located on two opposite sides of the rotary pull seat 4, first ends of the two first elastic members 5 are connected with the rotary pull seat 4, and second ends of the two first elastic members 5 are connected with the support 1.

When the driving component drives the whole bracket 1 to swing, the two groups of scraper blade components 2 can be driven to switch between an initial state and a cleaning state, and in the initial state, the two groups of scraper blade components 2 are lifted to be separated from a surface to be cleaned so as to be convenient for walking; in clean state, wherein a set of scraper blade subassembly 2 pushes down in order to with wait to clean the face laminating to in this side scraper blade subassembly 2 treats the face of cleaning and scrapes the brush washing, specifically, driving motor 3 drive support 1 rotates, drives and drags the mechanism action, drags two sets of scraper blade subassemblies 2 of mechanism pulling, realizes that two sets of scraper blade subassemblies 2 are lifting up and fall to switch over in turn between the state.

It will be appreciated that during cleaning, it may be the left squeegee assembly 2 that is depressed while the right squeegee assembly 2 continues to be lifted; or the right squeegee assembly 2 is depressed while the left squeegee assembly 2 continues to be lifted.

The initial state can be understood as the state before cleaning, and the cleaning is reset to the initial state after the cleaning is finished, so that the interference to the movement is avoided, and the road surface can walk conveniently; the cleaning state can be understood as the state when washing the use, and at this moment, one set of scraper blade subassembly 2 falls down and waits to clean the face laminating, changes into operation scraper blade subassembly into, realizes the brush cleaning, and another set of scraper blade subassembly 2 perk and wait to clean the face separation.

For example: when upwards wasing, downside scraper blade subassembly 2 can swing to pushing down the state and wait to clean the face laminating, when needs wash downwards, upside scraper blade subassembly 2 can swing to pushing down the state and wait to clean the face laminating, washs the back that finishes, and both sides scraper blade subassembly 2 resets to initial condition, and the cleaning robot of being convenient for removes on the road surface. Therefore, the two groups of scraper assemblies 2 can be tilted or fallen, the cleaning robot can carry out bidirectional cleaning only by moving up and down during cleaning, steering and turning around are not needed, the use is very convenient, and the cleaning effect and efficiency can be effectively improved.

Specifically, in the initial state, the two first elastic members 5 are respectively pulled by the driving motor 3, so that the support 1 is in a stable state, and when the initial state is switched to the cleaning state, for example, the driving motor 3 drives the rotary pull seat 4 to rotate to the left, the right squeegee assembly 2 will be pulled and lifted continuously; meanwhile, under the resultant force action of the gravity of the scraper component 2 and the pressure of the rotary pull seat 4, the left scraper component 2 is pressed down to be attached to a surface to be cleaned and is changed into an operation scraper component to realize cleaning, and the same principle is carried out when the driving motor 3 rotates rightwards; and after the cleaning is finished, switching to the initial state again. Therefore, the present invention can realize the state switching of the left and right squeegee assemblies 2 by controlling the forward and reverse rotation of the driving motor 3.

In addition, in the cleaning process, as the surface to be cleaned possibly has a raised barrier, the first elastic piece 5 can play a role in buffering, the scraper component 2 is prevented from colliding the barrier on the surface to be cleaned hard, the cleaning device is protected, so that the impact force can be prevented from being transmitted to the body of the cleaning robot, the stability of the whole body can be effectively improved, the normal operation of the cleaning process is ensured, the efficiency is improved, and the adaptability is high.

Therefore, the cleaning device provided by the embodiment of the invention can realize synchronous linkage control of the two groups of scraper blade assemblies 2 through one driving motor 3, so that the working efficiency can be improved, the structure can be simplified, the volume can be reduced, and the cost can be reduced; in addition, the stability of the scraper component 2 during cleaning can be improved through the transmission matching of the pulling mechanism and the mechanical design; can play the cushioning effect through first elastic component 5, dodge the barrier, protect belt cleaning device, effectively improve the stability of whole fuselage, have characteristics such as simple structure, stability height, safe and reliable, long service life, self-cleaning are effectual.
