The embodiment of the application provides a self-cleaning device of a cleaning mechanism and cleaning equipment, and solves the problems that the cleaning mechanism of the existing cleaning robot needs manual cleaning and the automation degree is low.

Example one

Referring to fig. 1, a self-cleaning device of a cleaning mechanism provided in an embodiment of the present application is used for cleaning the cleaning mechanism, and includes a cleaning chamber 10, a lifting rod 20, and a water spray assembly. When the cleaning mechanism 100 is installed, one end of the lifting rod 20 is connected to the inner wall of the cleaning chamber 10, the other end of the lifting rod 20 is hinged to the cleaning mechanism 100, the lifting rod 20 is used for driving the cleaning mechanism 100 to move towards the direction close to or away from the cleaning chamber 10, the water spraying assembly is installed in the cleaning chamber 10 and comprises a spraying head 30, the spraying head 30 is connected with the inner wall of the cleaning chamber 10, and the spraying head 30 is used for spraying water to the cleaning mechanism 100 to clean the cleaning mechanism 100 when the lifting rod 20 drives the cleaning mechanism 100 to move towards the direction close to the cleaning chamber 10 so that the cleaning mechanism 100 is retracted into the cleaning chamber 10.

Specifically, the cleaning mechanism 100 is located outside the cleaning chamber 10 during operation, referring to fig. 2, after the cleaning mechanism 100 operates for a period of time, the cleaning surface 101 of the cleaning mechanism 100 is stained, the lifting rod 20 lifts to drive the cleaning mechanism 100 to lift into the cleaning chamber 10, at this time, the spray head 30 sprays water to the cleaning surface 101 of the cleaning mechanism 100 to wash the stains on the cleaning surface 101 clean, and the dirty water generated by cleaning the cleaning surface 101 of the cleaning mechanism 100 is discharged from the passage at the bottom of the cleaning chamber 10 for the movement of the cleaning mechanism 100. The whole cleaning process does not need manual participation, time and labor are saved, and the cleaning of the cleaning mechanism 100 is automated.

Further, since the cleaning surface 101 of the cleaning mechanism 100 generally faces the ground, in order to enable the spray head 30 to spray water in alignment with the cleaning surface 101 of the cleaning mechanism 100, the other end of the lifting rod 20 may be connected to the cleaning mechanism 100 through a rotating connection member, the rotating connection member is rotatably connected to the lifting rod 20, the rotating connection member is connected to the cleaning mechanism 100, and the rotating connection member is used to drive the cleaning mechanism 100 to rotate when the cleaning mechanism 100 is retracted into the cleaning chamber 10, so that the cleaning surface 101 of the cleaning mechanism 100 faces the spray head 30. In this way, the cleaning mechanism 100 can be rotated by the rotation of the rotary connecting piece, so that the cleaning surface 101 of the cleaning mechanism 100 forms an inclined angle with the ground, specifically, the rotary connecting piece can be rotated towards the spray head 30, so that the spray head 30 is opposite to the cleaning surface 101 of the cleaning mechanism 100, and thus, all water sprayed by the spray head 30 can be ensured to impact on the cleaning surface 101, and the cleaning efficiency of the cleaning surface 101 is improved. Referring to fig. 5, in a preferred embodiment, the rotary connecting member is coaxially arranged with the lifting rod 20, the rotary connecting member is perpendicular to the cleaning surface 101 of the cleaning mechanism 100, the rotary connecting member is rotated 90 degrees, so that the cleaning mechanism 100 is also rotated 90 degrees, and then the cleaning surface 101 is rotated 90 degrees, so that the cleaning surface 101 after rotation is perpendicular to the ground, the spray head 30 is arranged so that the water spraying surface is perpendicular to the ground, and the water spraying surface of the spray head 30 is opposite to the cleaning surface 101, so that the spray head 30 can spray all water onto the cleaning surface 101, and sewage after cleaning the cleaning surface 101 can directly and vertically fall from the cleaning surface 101 and is discharged from the opening 11 at the bottom of the cleaning chamber 10. When the cleaning mechanism 100 is cleaned and works again, the lifting rod 20 is lowered to drive the cleaning mechanism 100 to exit the cleaning chamber 10, and then the rotating connecting piece is rotated by 90 degrees, so that the cleaning mechanism 100 also rotates by 90 degrees, and then the cleaning surface 101 rotates by 90 degrees, so that the rotated cleaning surface 101 is recovered to be parallel to the ground, and the ground is cleaned again by the clean cleaning surface 101.

It should be noted that, in order to quickly discharge the sewage after cleaning the cleaning surface 101 out of the cleaning chamber 10, as shown in fig. 1-2, a part of the bottom of the cleaning chamber 10 may be used as a passage port for the cleaning mechanism 100 to enter and exit the cleaning chamber 10, and at the same time, the function of sewage may be considered, and of course, the whole bottom of the cleaning chamber 10 may also be used as an outlet for sewage, so that the cleaning mechanism 100 can enter and exit the cleaning chamber 10 conveniently, and the sewage can be quickly discharged. However, it should be noted that when the whole bottom of the clean room 10 is used as the outlet of the sewage, the size of the outlet of the sewage is large, the discharged sewage directly falls on the ground, and at this time, the cleaning device needs to be placed in a fixed place, and the place does not need to be cleaned, so that the ground cleaned by the cleaning device cannot be polluted by the sewage which washes the cleaning mechanism 100 and is directly discharged from the outlet of the sewage.

The cleaning mechanism 100 in the first embodiment of the present application may be a dust pusher or a water absorption scraper, which is not limited in the first embodiment of the present application.

The inner side surface of the bottom wall of the cleaning chamber 10 is movably connected with a sealing cover plate 42, and the sealing cover plate 42 is used for detachably sealing the opening 11; the lifting rod 20 is used for driving the cleaning mechanism 100 to move away from the cleaning chamber 10 when the sealing cover plate 42 does not seal the opening 11, so that the cleaning mechanism 100 extends out of the cleaning chamber 10 through the opening 11 from the cleaning chamber 10; the cleaning chamber 10 is used for receiving the sewage after cleaning the cleaning mechanism 100 in a sealed state when the opening 11 is sealed by the sealing cover plate 42, and the cleaning chamber 10 is in a sealed state.

It should be noted that the sealing cover plate 42 is located at the position where the bottom wall of the cleaning chamber 10 is provided for the cleaning mechanism 100 to enter and exit from the cleaning chamber 10, that is, at the opening 11, and it is ensured that the size of the sealing cover plate 42, that is, the size of the opening 11, is larger than the size of the cleaning mechanism 100, so that when the cleaning mechanism 100 needs to be self-cleaned, the cleaning mechanism 100 can be taken into the cleaning chamber 10 from the opening 11, and then the sealing cover plate 42 is sealed at the opening 11, so that the opening 11 of the cleaning chamber 10 is completely shielded by the sealing cover plate 42, and thus the cleaning chamber 10 forms a sealed space, as shown in fig. 4, fig. 4 is a schematic diagram of a state that the cleaning mechanism 100 is taken into the cleaning chamber 10 for cleaning, at this time, sewage generated by cleaning the cleaning surface 101 of the cleaning mechanism 100 is only in the cleaning chamber 10 and will not splash to the outside to contaminate other components of the cleaning mechanism, and the whole self-cleaning process can clean the cleaning surface 101 of the cleaning mechanism 100 and can also avoid contaminating other components of the cleaning mechanism and even the external environment. When the cleaning mechanism 100 is cleaned and works again, the sealing cover plate 42 is detached from the opening 11, so that the position of the opening 11 corresponding to the entrance and exit of the cleaning mechanism 100 into and out of the cleaning chamber 10 is in an unsealed state, and the clean cleaning mechanism 100 can be withdrawn from the cleaning chamber 10 to perform the floor cleaning work again.

Furthermore, the self-cleaning device of the cleaning mechanism in the second embodiment of the present application can play a role of cleaning the cleaning surface 101 of the cleaning mechanism 100, and the cleaning chamber 10 can form a sealed space, so that the cleaning mechanism 100 can be taken into the cleaning chamber 10 when the cleaning mechanism 100 is not used, the cleaning mechanism 100 is kept clean and tidy, and the cleaning mechanism 100 is prevented from being always in the external environment and being stained, which leads to the cleaning mechanism 100 being cleaned before being used, and wastes time and labor.

Further, the bottom wall of the cleaning chamber 10 is provided with the sewage suction port 43, so that when the sewage generated by cleaning the cleaning surface 101 of the cleaning mechanism 100 is collected in the cleaning chamber 10, the sewage in the cleaning chamber 10 can be discharged through the sewage suction port 43, and the pollution to other parts of the cleaning device and even the external environment can be avoided.
