A disadvantage of this technical solution is that, once the area to be cleaned exceeds the clean water tank's capacity, the clean water tank must be refilled and the dirty water tank emptied multiple times to maintain continuous use of the machine until the cleaning target is achieved. This leads to the following problems: 1. Water usage is cumbersome, reducing labor efficiency and increasing the workload; 2. Water resources are wasted; and 3. Large-volume (large-capacity) equipment is required to extend the single-use time, reducing the practicality and functionality of the equipment.

[0004] In summary: the use process of the water structure in cleaning equipment has the disadvantages of complicated operation, reduced labor efficiency, increased labor burden, waste of water resources, and reduced practicality and functionality of the equipment. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of the water-using structure in the cleaning equipment in the prior art, such as complicated operation, reduced labor efficiency, increased labor burden, waste of water resources, and reduced equipment practicality and economy. It provides a sewage recovery and circulation system that is convenient in water use, reduces burden, improves labor efficiency, saves water resources, and improves equipment practicality and functionality.

The clean water tank is provided with a water outlet and a water inlet, and the recovery tank is provided with a sewage inlet. The machine body is connected to a water supply component, the clean water tank is connected to a water outlet valve component, and the recovery tank is connected to a quick-connect valve component. The water outlet valve component is detachably connected to one end of the water supply component, and the quick-connect valve component is detachably connected to the other end of the water supply component. A multi-stage filter component and an exhaust float component are installed in the recovery tank.

[0008] The clean water tank and the recovery tank are flexibly placed on the fuselage, and are connected to the water delivery component of the fuselage at the same time. Then, after the clean water tank and the recovery tank are fixed, the water channel connection between the clean water tank and the recovery tank is completed, so that the clean water tank is filled with water from the water inlet, the water is used at the water outlet, the sewage inlet absorbs the used sewage and enters the recovery tank, the multi-stage filter component in the recovery tank performs high-efficiency filtration, and the filtered water returns to the clean water tank for use, so as to realize the work flow of recycling the sewage to the clean water tank for recycling, thereby reducing the number of water additions in operation or completing the cleaning operation by recycling water after adding water once. While saving resources, it can not only ensure that the usage is sufficient, but also achieve the reduction of the volume of the mobile water supply equipment system and achieve more Less water is used to clean more areas; the multi-stage filtration component achieves and improves sewage purification, with high filtration efficiency and effectiveness, reducing emptying and ensuring the cleanliness of the circulating water; the exhaust float component allows sewage to flow smoothly into the recovery tank while preventing overflow; the clean water tank is connected to the outlet valve component for connecting to the outlet end of the delivery component, and the quick-connect valve component of the recovery tank is used to connect to the inlet end of the delivery component, allowing for quick connection and disconnection between the clean water tank and the recovery tank, making it easy to plug and unplug the clean water tank from the machine during use and water addition and cleaning, and the recovery tank from the machine during use and cleaning and maintenance. It is flexible in use and has a stable structural connection. The outlet valve component ensures one-way water flow through the valve body structure to prevent water leakage during use. This achieves the effects of convenient water use, reduced burden, improved labor efficiency, water resource conservation, improved practicality and functionality of the equipment, reduced emptying and rapid water discharge, smooth liquid flow while preventing water leakage, and flexible plug-in structure for stable connection, installation and maintenance.

[0009] Preferably, the water delivery assembly includes a water pump, a clean water tank water pipe, a recovery tank water pipe and a water pump control switch.

The water inlet of the water pump in the delivery assembly is connected to the water pipe of the tax bucket, and the water outlet is connected to the water pipe of the clean water tank. The water pump drives the filtered circulating water to enter the water pipe of the recovery tank through the quick-connect valve assembly, enter the water pipe of the clean water tank through the water pump, and finally enter the clean water tank, thereby realizing the water transportation flow. When the clean water tank is placed in the fuselage, it is connected to the clean water tank water pipe, and when the recovery tank is placed in the fuselage, it is connected to the recovery tank test tube, making installation quick and convenient. At the same time, after the clean water tank is placed in, the water pump control switch is pressed by the pressing block, thereby connecting the water pump control switch through the circuit between the pressing block and the water pump, and the circuit is immediately disconnected after the clean water tank is removed from the fuselage. This achieves the effect of improving the connection convenience between the structures and the safety of use.

[0010] Preferably, the clean water tank water pipe is connected with water channel connector 1, which is plugged into the water outlet valve assembly, the recovery tank water pipe is connected with water channel connector 2, which is plugged into the quick-connect valve assembly, the fuselage is connected with support frame 1, water pump mounting seat and support frame 2, support frame 1 is provided with slot 1, support frame 2 is provided with slot 2, water channel connector 1 is plugged into slot 1, water channel connector 2 is plugged into slot 2, and the water pump is detachably connected to the water pump mounting seat. One end of the clean water tank pipe is connected to the water outlet of the water pump, and the other end is equipped with a water channel connector 1 for connecting to the water outlet valve assembly. One end of the recovery tank pipe is connected to the water inlet of the water pump, and the other end is equipped with a water channel connector 2 for plugging into the quick-connect assembly to further improve the connection strength. At the same time, the fuselage is provided with a support frame 1 and a support frame 2 for fixing the clean water tank pipe and the recovery tank pipe to organize the lines and prevent line confusion. The water channel connector 1 is clipped onto the card slot 1, and the water channel connector 2 is clipped onto the card slot 2 to position and fix the structure, prevent structural displacement when connecting the water outlet valve assembly and the quick-connect valve assembly, and further provide a stable and quick connection foundation. The water pump is disassembled and connected to the fuselage through the water pump mounting seat, thereby facilitating subsequent maintenance. This achieves the effects of improving the efficiency of structural positioning and installation, facilitating subsequent maintenance, clarifying wiring, and achieving high efficiency and high stability in the docking between structures, which is conducive to the quick plugging and unplugging of the clean water tank and the recovery tank.

[0011] Preferably, the clean water tank is provided with a circulating water inlet, the water outlet and the circulating water inlet are both connected to a water channel pipe, a water channel connector is plugged into the water channel pipe in the circulating water inlet, the water channel pipe of the water outlet is connected to a water pipe, the circulating water inlet channel and the water outlet are both provided with a water outlet valve assembly, the water outlet valve assembly includes a valve column, a water stop plug, a valve seat and a spring, the water stop plug is connected to one end of the valve column, the other end of the valve column is connected to the valve seat, the spring is sleeved on the valve column, the water stop plug is clamped to the outside of one end of the water channel pipe, and the valve seat is movably connected to the inside of the other end of the water channel pipe through the spring. The clean water tank is provided with a circulating water inlet for connecting to the water passage pipe, and the water outlet is also connected to the water passage pipe. The water passage pipe is used to install the outlet valve assembly. The valve body of the outlet valve assembly is placed in the water passage pipe, and one end is extended into the pipe outlet of the water inlet and connected to the water stop plug, and the other end is placed in the water passage pipe and connected to the valve seat. The valve seat is close to the end of the water inlet of the water passage pipe, and the end of the water channel connector is inserted into the pipe outlet at this end, so that the circulating water is introduced into the water passage pipe through the water pump and sprayed from the water channel connector into the circulating water inlet. The spring is set When the valve is located in the circulating water inlet channel and is larger than the pipe orifice, the water stopper is pushed by the spring to compress the valve body and valve stem, making the cross-sectional area smaller than the pipe orifice of the circulating water inlet channel. This means that the water flow pushes the water stopper to move, opening the water channel pipe orifice to discharge water, allowing the circulating water to flow into the clean water tank. Similarly, continuous water supply causes the water flow in the clean water tank to flush the water stopper in the water channel pipe at the water outlet and flow out of the connected water pipe. After the water pump is stopped, the spring resets the water stoppers at both locations to stop the flow again, thus completing one-way water supply and rapid water stopping. This achieves the effect of stable connection between structures, realizing and guaranteeing strong one-way water flow, and preventing water leakage.

[0012] Preferably, the recycling box includes a recycling barrel, a recycling cover and a recycling cover base, the recycling barrel is connected to the fuselage, the recycling cover is clamped to the recycling barrel, the recycling cover is clamped to the recycling cover base, the quick-connect valve assembly includes a connecting water pipe and a connecting valve seat, the connecting valve seat is provided with a water passage, the connecting valve seat is detachably connected to the recycling cover base, water channel connector 2 is plugged into one end of the water passage, the other end of the water passage is connected to a quick-connect plug 1, the connecting water pipe is plugged into the recycling cover base, one end of the connecting water pipe is plugged into the quick-connect plug 1, and the other end of the connecting water pipe is connected to the multi-stage filter assembly.

The outer side of the recycling cover base has a structure with a sunken space to facilitate the placement of a structure including a quick-connect valve assembly. The recycling cover is then clamped to ensure the integrity of the surface is neat and flat. The connecting valve seat in the quick-connect valve assembly is connected to the recycling cover base and fixed, and then fixed again by the clamped recycling cover. The connecting valve seat is plugged into the water channel connector 2 through the water passage, and the other end is connected to one end of the connecting water pipe through the quick-connect plug 2, so that the connecting water pipe and the water channel connector 2 are connected. The other end of the connecting water pipe extends into the recycling bin and is connected to the multi-stage filter assembly, so that the filtered circulating water enters the connecting water pipe for transportation. The connection between the connecting valve seat and the recycling cover base is disassembled to facilitate the later aging maintenance of the connecting valve seat. This improves the integrity of the equipment, facilitates the quick and stable assembly between structures, and facilitates the smooth transportation of circulating water and later maintenance.

[0013] Preferably, the multi-stage filtration assembly includes a foam filter, a primary sewage filter and a secondary sewage filter, which are sequentially connected from the outside to the inside, one end of the secondary sewage filter is against the bottom of the recovery barrel, and the other end of the secondary sewage filter is sealed with the base of the recovery cover. A pipe sleeve connector is clamped in the secondary sewage filter, one end of the pipe sleeve connector is provided with a water inlet, the water inlet is connected to a metal filter, and the other end of the pipe sleeve connector is connected to a quick-connect plug 2. The connecting water pipe is placed in the secondary sewage filter, and the quick-connect plug 2 is plugged into the connecting water pipe. In the multi-stage filtration component, the first-level sewage filter is sleeved on the outside of the second-level sewage filter, and the foam filter is sleeved on the outside of the first-level sewage filter, so as to achieve efficient filtration effect and reduce emptying phenomenon, and at the same time achieve multi-stage filtration effect on sewage, improve water cleanliness and reuse rate, the lower end of the second-level sewage filter is against the bottom of the recycling barrel, and the upper end is sealed with the inner side of the recycling cover base, and when connected, the connecting water pipe enters the second-level sewage filter, and the connecting water pipe is connected to the clamping pipe sleeve connector, one end of the pipe sleeve connector is clamped on the inner wall of the pipe sleeve connector and the quick-connect plug at the other end is connected to the connecting water pipe The connections are simultaneously connected, allowing the connecting water pipe to be fixed in the secondary sewage filter through the pipe sleeve connector. The extension length of the other end of the connecting water pipe can be adjusted to prevent the connecting water pipe from being blocked due to excessive extension. At the same time, the water inlet port of the connecting water pipe and the pipe sleeve connector is kept at a low position to cope with the situation where the recovered liquid level gradually decreases due to possible water loss during the use of circulating water, ensuring continuous suction. A metal filter is installed at the water inlet to re-filter the filtered water while supporting the structural strength of the water inlet of the pipe sleeve connector, making the installation of the pipe sleeve connector more stable. The results are to enhance the cleanliness and reuse rate of water, reduce emptying, improve the flexibility of structural installation, and ensure the stability of water inlet transmission.

One end of the guide channel tube is connected to the air filter in the exhaust float assembly. The portion of the air filter with air holes is plugged into the channel tube with a hole, allowing water to enter through the air holes and exit through the other end of the guide channel tube, which is connected to the exhaust pipe. The exhaust pipe is connected to the bottom of the recovery barrel and has a hollow structure that is connected to the outside world. That is, when the recovery cover base is engaged, the guide channel tube port is plugged into the exhaust pipe port to connect the recovery barrel with the outside world. The air holes on the end and side surfaces ensure exhaust and recovery efficiency. The float mounting seat is used to connect the float member and serve as the rotation fulcrum of the float member. The float member pushes the stop plate as the liquid level rises. Before the recovery volume exceeds the set value, the stop plate is pushed by the float member to close the guide channel tube. The cooperation between the float member and the air filter prevents recovery overflow. This achieves the effect of stable connection between the structures, overflow prevention, and smooth recovery.

[0015] Preferably, the base of the recovery cover is connected to a curved water guide panel, which is positioned within the recovery tank and opposite the sewage inlet. This curved water guide panel is connected to the base of the cover and opposite the sewage inlet. This allows sewage entering the recovery tank to be diverted by the curved water guide panel, buffering its flow while vertically falling to the bottom of the recovery tank, where the liquid level is raised and collected.

The water inlet cap is used to close the water inlet to prevent water from spilling out during movement. After the water inlet cap is inserted into the water inlet, the clamping block passes through the limiting groove and rotates, causing the fixed ring to limit the clamping block and prevent the water inlet cap from easily falling out. At the same time, when removing the water inlet cap, the user can simply grasp the gripping block and rotate it. This improves the stability of the clean water tank and the ease of structural operation.

[0017] Preferably, the clean water tank and the recycling cover are both provided with a limiting groove, the limiting groove is rotatably connected to a handle, the handle is engaged with the limiting groove, and the limiting groove is provided with a clearance groove, the clearance groove is close to the middle of the handle. The water inlet on the end face of the clean water tank is connected to the inside of the tank, and the water inlet is plugged into the water filling cover, so that the water filling cover can be opened and closed. At the same time, the water filling cover is quickly fixed by a block into the limiting groove to prevent the water filling cover from falling; the clean water tank and the recycling cover are both provided with a limiting groove, the end of the handle is rotatably connected to the limiting groove and can be placed in the limiting groove for storage, and the limiting groove is provided with a recessed clearance groove, so that when operating the handle, a finger can be easily inserted from the clearance groove for grasping, thereby facilitating the rapid lifting of the clean water tank for water addition or the removal of the recycling cover for filter element maintenance. This achieves the effect of improving the convenience of operation, the convenience and efficiency of using the clean water tank and the recycling tank.

[0018] Preferably, a connecting rod and a handle are provided at the upper end of the body. One end of the connecting rod is connected to the body, and the other end of the connecting rod is connected to the handle. The angle between the handle and the connecting rod is less than 180 degrees. The side of the lower end of the body is rotatably connected to a roller. The upper end of the body is connected to the handle via a connecting rod, and the lower end is connected to a roller, which can easily push the device. At the same time, the handle is connected to the connecting rod at a non-coaxial angle of less than 180 degrees, which is convenient for hand grasping and applying force. The roller is placed on the side of the lower end of the body close to the upper connecting rod, so that it can be fixed in a parked state while being easy to move and prevent the body from rolling away. This improves the convenience and comfort of using the device.

[0019] The beneficial effects of the present invention are: the use of water through the circulation system is convenient, the burden is reduced, and labor efficiency is improved; water resources are saved; the practicality and functionality of the equipment are improved; emptying is reduced and water is discharged quickly; liquid circulation is smooth while preventing water leakage; the structure is flexible to plug and unplug, which is convenient for stable connection and installation and maintenance; safety of use is improved; the integrity of the equipment is improved; and the stability, comfort and convenience of structural operation are improved.
