[0049] See Figures 1-8 As shown;

[0050] A wastewater circulation filtration device for cleaning includes a water tank, a hollow shaft motor, a filter structure, and a circulation structure. The filter structure is installed inside the water tank. The hollow shaft motor drives the filter structure to rotate while the water tank is fixed in position. The hollow shaft motor has a motor body and a hollow shaft 1. The filter structure has a filter element, a water collection tray, and a flange. The filter element is a filamentous hollow fiber membrane. The water collection tray is a hollow structure with a reclaimed water outlet. The water collection tray also has a reclaimed water inlet integrated with and connected to the filter element. One end of the hollow shaft 1 is fixed to the flange and sealed to the reclaimed water outlet. The circulation structure has a wastewater inlet pipe connected to the water tank and a wastewater suction pump body installed on the wastewater inlet pipe. It also includes a sealing ring 2, a reclaimed water outlet pipe 3, a pump 4, a groove 5, a conductive slip ring 6, and a mounting plate 7.

[0051] Specifically, a sealing ring 2 is installed between the hollow shaft 1 and the water tank. Grooves 5 are distributed on the bottom wall of the water tank, and the sealing ring 2 is installed in the grooves 5. The sealing ring 2 forms a sealed contact with the water tank and the hollow shaft 1. After the sewage is filtered through the filter structure, it will flow into the hollow shaft 1. During this process, the water in the water tank will not leak from the connection of each structure, ensuring the safe use of the device.

[0052] Specifically, the hollow shaft 1 is partially hollow and partially solid. The middle section of the hollow shaft 1 is sealed, and both ends are hollow. The sealed part is a solid section 12, and the hollow parts at both ends are the first hollow section 13 and the second hollow section 14. The first hollow section 13 extends upward into the water tank, and the top of the first hollow section 13 is sealed and connected to the reclaimed water outlet to transport filtered water. Water outlets 11 are opened at corresponding positions of the first hollow section 13 and the second hollow section 14. The water outlets 11 are connected to the reclaimed water outlet pipe 3. The inlet and outlet of the water pump 4 are connected to the corresponding reclaimed water outlet pipe 3. After the water pump 4 is started, it can continuously pump the filtered water out of the water tank. The water flows through the first hollow section 13, the reclaimed water outlet pipe 3, and the second hollow section 14 in sequence, and then is discharged from the bottom of the second hollow section 14.

[0053] The hollow shaft 1 is equipped with an external mounting plate 7, and the water pump 4 is fixed on the mounting plate 7, which facilitates the installation and connection of the water pump 4 with the reclaimed water outlet pipe 3, reduces space occupation, and optimizes the overall space layout.

[0054] Furthermore, when the device is used in cleaning equipment (such as floor scrubbers), the bottom end of the second hollow section 14 can be connected to the brush plate 8. Water filtered by the filter structure flows out through the second hollow section 14 to the bottom of the brush plate 8. During the rotation of the brush plate 8, the water flowing out through the second hollow section 14 can be used to scrub the floor.

[0055] Preferably, a conductive slip ring 6 is installed on the hollow shaft 1. The rotor part (inner ring) of the conductive slip ring 6 is rigidly connected to the hollow shaft 1 and rotates synchronously with the hollow shaft 1. The stator part (outer ring) of the conductive slip ring 6 is fixedly installed on the water tank. The wires led out from the stator part of the conductive slip ring 6 are connected to the power supply and signal source. The rotor part of the conductive slip ring 6 contacts and slides with the stator part to realize the transmission of electricity and signals. The wires led out from the rotor part of the conductive slip ring 6 are connected to the water pump 4. After the hollow shaft motor starts, the hollow shaft 1 rotates, and the rotor part of the conductive slip ring 6, the reclaimed water outlet pipe 3, and the water pump 4 rotate synchronously. That is, the positions of the rotor part of the conductive slip ring 6, the reclaimed water outlet pipe 3, and the water pump 4 remain fixed, which can avoid the problem of wire entanglement.

[0056] The cleaning equipment has a base plate at the bottom, and the hollow shaft motor is fixedly mounted on the base plate.

[0057] The specific work process is as follows:

[0058] When the second hollow section 14 is not connected to other structures, the hollow shaft motor can drive the filter structure to filter sewage independently. At this time, the hollow shaft motor is not limited to unidirectional rotation or forward and reverse rotation.

[0059] When in use, connect to the power supply and control the movement of the equipment, the start and stop of the hollow shaft motor and the water pump 4 through the controller. During the movement of the equipment, the hollow shaft motor runs continuously to prevent the filter element of the filter structure from clogging and to continuously filter the sewage in the water tank. The filtered water passes through the first hollow section 13, the regenerated water outlet pipe 3, and the second hollow section 14 in sequence and is discharged from the lower opening of the second hollow section 14, which can be discharged to the ground for use.

[0060] When the second hollow section 14 is connected to the brush plate 8, the hollow shaft motor synchronously drives the filter structure and the brush plate 8.

[0061] When in use, connect the power supply and control the movement of the equipment, the start and stop of the hollow shaft motor and the water pump 4 through the controller. During the movement of the equipment, the hollow shaft motor runs continuously to filter the sewage in the water tank through the filter structure. The filtered water passes through the first hollow section 13, the regenerated water outlet pipe 3, and the second hollow section 14 in sequence, and finally flows into the bottom of the brush plate 8 or the ground through the second hollow section 14. The brush plate 8 rotates forward while washing the ground clean with water flow. That is, the rotation of the hollow shaft 1 can simultaneously drive the filter structure to filter sewage and drive the brush plate 8 to rotate to wash and clean the ground.

[0062] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
