The brush plate is located below the chassis frame, and a vertical mounting plate is installed on the chassis frame located behind the horizontal support plate. The spray assembly includes a liquid storage cup, a liquid spray boost pipeline and a nozzle. The liquid storage cup and the liquid spray boost pipeline are arranged on the vertical mounting plate.

[0006] The floor care cleaning robot also includes a floor cleaning device, the floor cleaning device is installed at the front of the chassis frame, and the floor cleaning device includes a push plate frame lifting assembly, the push plate frame lifting assembly includes a push plate frame, a square push plate, an electric push rod, a connecting shaft, an upper swing arm fixed shaft, a lower swing arm fixed shaft, two lower swing arms, two upper swing arms, two swing arm connecting plates and an electric push rod fixing seat, two swing arm connecting plates are respectively installed on both sides of the middle of the push plate frame, the upper swing arm fixed shaft and the lower swing arm fixed shaft are respectively fixed and installed in parallel from top to bottom The electric push rod fixing seat is installed at the bottom of the front of the chassis frame, and the electric push rod fixing seat is installed on the electric push rod fixing seat.

The swinging ends of the two upper swing arms and the swinging ends of the two lower swing arms are respectively fixedly installed in parallel from top to bottom on the upper and lower ends of the two swing arm connecting plates.

[0007] The present invention can realize the crystal plating care function of the floor surface by providing a floor care device including a brush plate assembly and a liquid spray assembly, so that the floor surface obtains a hard protective coating, thereby achieving the care effect of the floor surface being scratch-resistant, corrosion-resistant and crack-resistant. Among them, the liquid spray assembly is used to spray the crystal plating liquid onto the floor surface, that is, the crystal plating liquid is first manually injected into the liquid storage cup, and then the pressurized crystal plating liquid is transported to the nozzle of the nozzle through the liquid spray boosting pipeline and sprayed onto the floor surface. At the same time, the lifting motor of the brush plate assembly drives the elastic buffer assembly, the rotating motor and the brush plate downward in sequence through the vertically arranged lifting motor output shaft until the brush plate and the floor surface achieve buffering contact. During the downward movement of the brush plate, the rotating motor is synchronously started and the brush plate is driven to rotate through the output shaft of the rotating motor, so as to achieve the technical effect of the rotating brush plate grinding the floor surface adhered with the pressurized crystal plating liquid until a hard protective coating is obtained.

[0008] The working principle of the liquid spray assembly of the present invention is: first, the crystal plating liquid is manually injected into the liquid storage cup, then the infusion solenoid valve is opened and the crystal plating liquid is quantitatively extracted from the liquid storage cup into the pressure cup through the peristaltic pump, and then the infusion solenoid valve is closed, and the booster pump is started to pressurize the crystal plating liquid. The purpose of pressurization is to make the crystal plating liquid uniform. When the pressure sensor detects that the pressure in the pressure cup reaches the set pressure, the booster pump is turned off. After that, according to the actual grinding needs of the floor surface, the switch of the liquid spray solenoid valve is controlled in real time to spray the pressurized crystal plating liquid along the nozzle outlet to the floor surface to be ground.

[0009] Furthermore, the elastic buffer assembly includes an upper buffer plate, a linear optical axis, a fixed linear bearing, a buffer linear bearing, a buffer spring and a lower buffer plate. The linear optical axis is fixedly installed on the lower surface of the horizontal support plate. The fixed linear bearing, the upper buffer plate, the buffer spring, the buffer linear bearing and the lower buffer plate are sequentially installed along the linear optical axis from top to bottom. The rotating motor is fixedly installed on the upper surface of the lower buffer plate, and the upper buffer plate is fixedly connected to the output shaft of the lifting motor.

[0010] The lower buffer plate can move relative to the upper buffer plate along a linear optical axis to compress or stretch the buffer spring, thereby achieving a buffering effect through the elastic force of the buffer spring.

[0011] Furthermore, a buffer limiting rod is installed between the upper buffer plate and the lower buffer plate, and the buffer limiting rod is used to limit the buffer stroke of the relative movement between the lower buffer plate and the upper buffer plate.

[0012] Furthermore, two brush disc assemblies are arranged in parallel, two liquid spray assemblies are arranged in parallel, each liquid spray assembly is provided with two nozzles in parallel, and two nozzles are configured around the periphery of each brush disc.

[0013] The floor cleaning device provided in the present invention can clean the floor surface as needed during the movement of the floor care cleaning robot, wherein the electric push rod is used to extend and retract the push plate frame up and down and drive the square push plate on the push plate frame to extend and retract up and down. When the square push plate is needed to clean the floor surface, the electric push rod pushes the push plate frame to move downward and synchronously drives the square push plate on the push plate frame to move downward until it contacts the floor surface; when the square push plate completes the cleaning operation of the floor surface, the electric push rod pulls the push plate frame to move upward and synchronously drives the square push plate on the push plate frame to move upward and separate from the floor surface to return to its initial position.

[0014] The push plate frame lifting assembly operates as follows: the electric push rod is activated, and its push rod head drives the connecting shaft downward. The connecting shaft then simultaneously drives the two upper and lower swing arms at both ends of the connecting shaft downward. The two upper and lower swing arms then simultaneously drive the two swing arm connecting plates downward. The two swing arm connecting plates then simultaneously drive the push plate frame downward. The upward movement process is the reverse of the aforementioned downward movement process.

[0015] The two gears are connected with each other through the two guide wheels, and the two guide wheels are connected with each other through the two guide wheels, and the two guide wheels are connected with each other through the two guide wheels.

[0016] When the cleaning cloth surface at the bottom of the square push plate is sticky with a lot of dust, debris and other dirt after being used for a period of time, the stepper motor can be started and the dual-axis output end of the reversing reducer drives the two push plate reversing transmission shafts to rotate synchronously 90 degrees through the two couplings. Subsequently, the two push plate reversing dynamic shafts drive the two synchronous driving wheels to rotate synchronously 90 degrees. The two synchronous driving wheels drive the two synchronous driven wheels to rotate synchronously 90 degrees through two synchronous belts. The two synchronous driven wheels drive the square push plate to rotate synchronously 90 degrees so that the clean cleaning cloth surface adjacent to the used unclean cloth surface on the square push plate can be replaced to continue cleaning the floor surface. By analogy, when the four clean cleaning cloth surfaces of the square push plate have been replaced and used up, the cleaning cloth on the square push plate can be replaced manually.

[0017] The overall shape of the square push plate is a hexahedron, which includes two end faces along the length direction and four side faces along the length direction. The circumferential surface of the square push plate is the four side faces.

After processing, the control mainboard then issues the various functional instructions to the functional units of each component or device as needed to automatically start the operation. The power supply provides electrical energy to the various electrical components of the local board care and cleaning robot.

The control assembly is respectively connected to the brush disc assembly and the liquid spray assembly.

[0037] This embodiment provides a floor care device comprising a brush plate assembly and a liquid spray assembly to achieve a crystal coating care function on the floor surface, thereby providing the floor surface with a hard protective coating, thereby achieving a scratch-resistant, corrosion-resistant, and crack-resistant floor surface care effect. The liquid spray assembly is used to spray the crystal coating liquid onto the floor surface. Specifically, the crystal coating liquid is first manually injected into the liquid storage cup 26, and then the pressurized crystal coating liquid is delivered to the nozzle 15 through the liquid spray booster pipeline and sprayed onto the floor surface. Simultaneously, the lifting motor 11 of the brush plate assembly drives the elastic buffer assembly, the rotary motor 12, and the brush plate 17 downwardly via the vertically arranged lifting motor output shaft 28 until the brush plate 17 achieves buffering contact with the floor surface.

[0039] The working principle of the liquid spraying assembly of this embodiment is as follows: first, the crystal plating liquid is manually injected into the liquid storage cup 26, then the infusion solenoid valve is opened and the crystal plating liquid is quantitatively extracted from the liquid storage cup 26 into the pressure cup 25 through the peristaltic pump 22, and then the infusion solenoid valve is closed, and the booster pump 23 is started to pressurize the crystal plating liquid.

Thereafter, according to the actual grinding needs of the floor surface, the switch of the liquid spraying solenoid valve 24 is controlled in real time to spray the pressurized crystal plating liquid along the nozzle of the nozzle 15 onto the floor surface to be ground.

The rotating motor 12 is fixedly installed on the upper surface of the lower buffer plate 31, and the upper buffer plate 32 is fixedly connected to the lifting motor output shaft 28.

[0041] In this embodiment, the lower buffer plate 31 can move relative to the upper buffer plate 32 along the linear optical axis 21 to compress or stretch the buffer spring 20 , thereby achieving a buffering effect through the elastic force of the buffer spring 20 .

When the square push plate 4 is needed to clean the floor surface, the electric push rod 5 pushes the push plate frame 3 to move downward and simultaneously drives the square push plate 4 on the push plate frame 3 to move downward until it contacts the floor surface; when the square push plate 4 completes the cleaning operation of the floor surface, the electric push rod 5 pulls the push plate frame 3 to move upward and simultaneously drives the square push plate 4 on the push plate frame 3 to move upward and detach from the floor surface to return to its initial position.
