Description

A wastewater recycling system Technical Field

[0001] This invention relates to the field of cleaning equipment technology, and more particularly to a wastewater recycling system. Background Technology

[0002] In daily life, we need to clean floors or carpets using cleaning equipment, such as floor cleaning machines, also called floor scrubbers. These are cleaning machines suitable for cleaning hard floors, simultaneously sucking up wastewater and removing it from the site. They have advantages such as being environmentally friendly, energy-saving, and highly efficient. Modern cleaning machines include a water system, which typically consists of a clean water tank and a wastewater tank. The clean water tank is used to add water for standby and for rinsing, while the wastewater tank is used to collect residual water after use.

[0003] Chinese Patent Authorization Announcement No.: CN 220459304 U, Authorization Announcement Date: February 9, 2024. This utility model relates to a floor cleaning machine, including a body assembly, on which a clean water tank assembly and a wastewater tank assembly are detachably mounted. A floor brush assembly is mounted at the lower end of the body assembly, and a metal support rod is mounted at the lower end of the body assembly. The floor brush assembly has a fixing groove, and the metal support rod has a locking component for controlling the metal support rod to be relatively fixed to the fixing groove. The shortcomings of this technical solution are: once the area to be cleaned exceeds the capacity of the clean water tank, it is necessary to add water to the clean water tank and empty the wastewater tank multiple times to keep the equipment running until the cleaning target is completed. This leads to the following problems: 1. Cumbersome water operation, reduced labor efficiency, and increased labor burden; 2. Waste of water resources; 3. The need to purchase large-volume (large-capacity) equipment to extend the single use time, reducing the practicality and functionality of the equipment.

[0004] In summary, the water-using structures in cleaning equipment suffer from drawbacks such as cumbersome operation, reduced labor efficiency, increased labor burden, waste of water resources, and reduced equipment practicality and functionality. Summary of the Invention

[0005] The present invention aims to overcome the shortcomings of existing water-using structures in cleaning equipment, such as cumbersome operation, reduced labor efficiency, increased labor burden, waste of water resources, and reduced equipment practicality and economy. It provides a wastewater recycling system that is convenient to use water, reduces the burden, improves labor efficiency, saves water resources, and enhances the practicality and functionality of the equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wastewater recycling system includes a main body, a clean water tank, and a recycling tank. The clean water tank has an outlet and a filling port, and the recycling tank has a wastewater inlet. The main body is connected to a water supply assembly, the clean water tank is connected to an outlet valve assembly, and the recycling tank is connected to a quick-connect valve assembly. The outlet valve assembly is detachably connected to one end of the water supply assembly, and the quick-connect valve assembly is detachably connected to the other end of the water supply assembly. A multi-stage filtration assembly and an exhaust float assembly are installed inside the recycling tank.

[0008] The clean water tank and recycling tank are flexibly placed on the machine body and connected to the water supply components, thus fixing them in place and completing the water channel connection between them. This creates a process where water is added to the clean water tank through the inlet, used at the outlet, and the wastewater absorbed by the inlet flows into the recycling tank. The recycling tank undergoes high-efficiency filtration through a multi-stage filtration system, and the filtered water is then returned to the clean water tank via a drainage component. This achieves a wastewater recycling process, reducing the number of water additions or allowing for a single water addition for complete cleaning. This saves resources while ensuring sufficient water supply, reducing the size of the mobile water supply system, and enabling more efficient water usage. Less water is used to clean more areas; multi-stage filtration components improve wastewater purification, reduce filtration efficiency and effectiveness, minimize emptying, and ensure the cleanliness of circulating water; an exhaust float assembly allows for smooth water intake into the recovery tank while preventing overflow; the clean water tank is connected to an outlet valve assembly for connecting to the outlet end of the conveying assembly, and the recovery tank has a quick-connect valve assembly for connecting to the inlet end of the conveying assembly, enabling quick connection and disconnection of the clean water tank and recovery tank. This allows for easy insertion and removal of the clean water tank and recovery tank during use and water filling / cleaning, and vice versa, providing flexible operation and stable structural connections. The outlet valve assembly ensures unidirectional water flow through its valve body structure to prevent leakage during use. This achieves the effects of convenient water use, reduced workload, increased labor efficiency, water conservation, improved equipment practicality and functionality, reduced emptying, rapid water output, smooth liquid flow while preventing leakage, and flexible insertion and removal for stable connection, installation, and maintenance.

[0009] Preferably, the water supply assembly includes a water pump, a clean water tank pipe, a recovery tank pipe, and a water pump control switch. Both the water pump and the water pump control switch are connected to the machine body. One end of the clean water tank pipe is connected to the water pump, and the other end is connected to the outlet valve assembly. One end of the recovery tank pipe is connected to the water pump, and the other end is connected to the quick-connect valve assembly. The clean water tank is connected to a push-button block, and the water pump control switch is electrically connected to the water pump for opening and closing via the push-button block. In the conveying assembly, the water pump's inlet is connected to the tax bin's water pipe, and its outlet is connected to the clean water tank's water pipe. Driven by the pump, filtered circulating water enters the recovery tank's water pipe through a quick-connect valve assembly, then flows through the pump into the clean water tank's water pipe, and finally into the clean water tank, thus achieving water flow. The clean water tank is connected to the clean water tank's water pipe when placed in the machine body, and the recovery tank is connected to the recovery tank's test tube when placed in the machine body, making installation quick and convenient. After the clean water tank is placed in, a pressing block activates the water pump control switch, connecting the switch via the circuit between the pressing block and the water pump. This circuit is immediately disconnected after the clean water tank is removed from the machine body. This improves the convenience of structural connections and enhances operational safety.

[0010] Preferably, the water pipe of the clean water tank is connected to a water connector 1, which is plugged into the water outlet valve assembly. The water pipe of the recovery tank is connected to a water connector 2, which is plugged into the quick-connect valve assembly. The machine body is connected to a support frame 1, a water pump mounting base, and a support frame 2. The support frame 1 has a slot 1, and the support frame 2 has a slot 2. The water connector 1 is engaged with the slot 1, and the water connector 2 is engaged with the slot 2. The water pump is detached and connected to the water pump mounting base. One end of the water pipe in the clean water tank is connected to the outlet of the water pump, and the other end is equipped with a water connector for connecting to the outlet valve assembly. One end of the water pipe in the recovery tank is connected to the inlet of the water pump, and the other end is equipped with a second water connector for connecting to the quick-connect assembly, further improving connection strength. Simultaneously, support frames one and two are installed within the machine body to fix the water pipes in the clean water tank and recovery tank, organizing the wiring and preventing tangling. Water connector one snaps into slot one, and water connector two snaps into slot two, positioning and fixing the structure to prevent displacement during connection of the outlet valve assembly and quick-connect valve assembly, further providing a stable and quick connection foundation. The water pump is detachably connected to the machine body via a water pump mounting base, facilitating later maintenance. This achieves the effects of improved structural positioning and installation efficiency, convenient later maintenance, clear wiring, high efficiency and stability of structural connections, and facilitates quick insertion and removal of the clean water tank and recovery tank.

[0011] Preferably, the clean water tank is equipped with a circulating water inlet, and both the outlet and the circulating water inlet are connected to a water passage pipe. A water connector is inserted into the water passage pipe inside the circulating water inlet. The water passage pipe at the outlet is connected to a water pipe. Both the circulating water inlet and the outlet are equipped with an outlet valve assembly. The outlet valve assembly includes a valve stem, a stop plug, a valve seat, and a spring. The stop plug is connected to one end of the valve stem, and the other end of the valve stem is connected to the valve seat. The spring is sleeved on the valve stem. The stop plug is placed outside one end of the water passage pipe and contacts one end of the water passage. The valve seat is limited inside the water passage pipe by the spring. The clean water tank has a circulating water inlet connected to a water passage pipe, and an outlet also connected to a water passage pipe. The water passage pipe houses the outlet valve assembly. The valve body of the outlet valve assembly is placed inside the water passage pipe, with one end extending into the outlet pipe and connected to a stop plug, and the other end placed inside the water passage pipe and connected to a valve seat. The valve seat is positioned close to the end of the water passage pipe where water enters, and simultaneously, the end of water connector one is inserted into this end pipe. This allows circulating water to be drawn in by the water pump and sprayed from water connector one into the circulating water inlet of the water passage pipe. A spring is placed... The water inlet channel pipe is directly larger than the pipe opening diameter. At this point, the stop plug is compressed by the thrust spring. The cross-sectional area of ​​the valve body and valve stem is smaller than the pipe opening size. This means the water flow pushes the stop plug to open the water passage pipe, allowing water to flow into the clear water tank. Similarly, continuous water supply causes the water in the clear water tank to open the stop plug in the water passage pipe at the outlet, allowing water to flow out through the connected water pipe. After the water pump stops, the spring resets the stop plugs at both locations, restoring flow control and thus completing unidirectional water supply and rapid water shut-off. This achieves stable structural connections, ensures effective unidirectional water flow, and prevents leakage.

[0012] Preferably, the recycling bin includes a recycling bucket, a recycling cover, and a recycling cover base. The recycling bucket is connected to the machine body, the recycling cover base is snapped into the recycling bucket, and the recycling cover is snapped into the recycling cover base. The quick-connect valve assembly includes a connecting water pipe and a connecting valve seat. The connecting valve seat has a water passage. The connecting valve seat is detachably connected to the recycling cover base. A second water connector is inserted into one end of the water passage, and a quick-connect plug is connected to the other end of the water passage. The connecting water pipe is inserted into the recycling cover base, one end of the connecting water pipe is inserted into the quick-connect plug, and the other end of the connecting water pipe is connected to the multi-stage filter assembly. The recycling bin is placed on the machine body. The recycling bin has an open-end structure, with a recycling cover base snapped into the opening. The outer side of the recycling cover base has a recessed design to accommodate components including the quick-connect valve assembly. The snap-fit ​​design ensures a clean and flat surface. The connecting valve seat of the quick-connect valve assembly is fixed to the recycling cover base and then secured by the snap-fit ​​cover. The connecting valve seat connects to the water pipe connector two via a water passage, and its other end connects to one end of the connecting water pipe via a quick-connect plug two, connecting the connecting water pipe to the water pipe connector two. The other end of the connecting water pipe extends into the recycling bin and connects to the multi-stage filtration assembly, allowing filtered circulating water to enter the connecting water pipe for transportation. The detachable connection between the connecting valve seat and the recycling cover base facilitates future maintenance due to aging. This design improves the overall integrity of the equipment, promotes quick and stable assembly between structures, ensures smooth circulating water transportation, and facilitates future maintenance.

[0013] Preferably, the multi-stage filtration assembly includes a foam filter, a primary wastewater filter, and a secondary wastewater filter, which are nested together from the outside to the inside. One end of the secondary wastewater filter abuts against the bottom of the recycling bin, and the other end is sealed to the base of the recycling cover. The secondary wastewater filter is equipped with a pipe fitting connector. One end of the pipe fitting connector has a water inlet connected to a metal filter screen, and the other end of the pipe fitting connector is connected to a quick-connect plug. The connecting water pipe is placed inside the secondary wastewater filter, and the quick-connect plug is inserted into the connecting water pipe. In a multi-stage filtration system, the primary wastewater filter is fitted over the secondary wastewater filter, and the foam filter is fitted over the primary wastewater filter. This achieves high-efficiency filtration, reduces emptying, and simultaneously provides multi-stage filtration of wastewater, improving water cleanliness and reuse rates. The lower end of the secondary wastewater filter rests against the bottom of the recycling bin, while its upper end is sealed to the inner side of the recycling cover base. During connection, a water pipe enters the secondary wastewater filter and connects to a snap-fit ​​pipe fitting connector. One end of the pipe fitting connector is snapped onto the inner wall of the pipe fitting connector, and the other end's quick-connect plug connects to the water pipe. The connection is made simultaneously, thus fixing the connecting water pipe within the secondary wastewater filter via the pipe sleeve connector. This allows adjustment of the extension length of the other end of the connecting water pipe and prevents over-extension and blockage of the pipe port, ensuring continuous flow. Simultaneously, it maintains a low position for the inlet ports of the connecting water pipe and pipe sleeve connector to address potential water loss during circulating water use, which could lead to a gradual decrease in the recovered liquid level, ensuring continuous intake. A metal filter screen is installed at the inlet for further filtration of the filtered water, while also supporting the structural strength of the pipe sleeve connector's inlet section, making the pipe sleeve connector installation more stable. This achieves the effects of enhancing water cleanliness and reuse rate, reducing air evacuation, improving structural installation flexibility, and ensuring stable water delivery.

[0014] Preferably, the exhaust float assembly includes a float component and an air duct filter. The recovery cover base is connected to a flow guide pipe and a float mounting seat. An exhaust pipe is connected inside the recovery tank. One end of the exhaust pipe is connected to the outside of the recovery tank. The air duct filter has several air holes on its side and one end. The other end of the air duct filter is connected to a baffle plate. The air duct filter is inserted into one end of the flow guide pipe, and the other end of the exhaust pipe is inserted into the other end of the flow guide pipe. The float component is rotatably connected to the float mounting seat. The inner side of the recovery cover base is connected to a flow guide pipe, which is an integral part of the recovery cover base. One end of the flow guide pipe is connected to the air filter in the exhaust float assembly. The perforated part of the air filter is inserted into the flow guide pipe, allowing the incoming water airflow to enter through the perforation and exit through the other end of the flow guide pipe, which is connected to the exhaust pipe. The exhaust pipe is connected to the bottom of the recovery tank and is a hollow structure that connects to the outside. That is, when the recovery cover base is snapped on, the end of the flow guide pipe is inserted into the exhaust pipe port to achieve communication between the recovery tank and the outside. The perforations on the end face and side ensure exhaust and recovery efficiency. The float mounting base is used to connect the float component and serve as the fulcrum for the rotation of the float component. This achieves the effects of stable connection between structures, prevention of overflow, and smooth recovery.

[0015] Preferably, the base of the recovery cover is connected to a water-guiding curved panel, which is placed inside the recovery tank and positioned opposite the wastewater inlet. This arrangement of the water-guiding curved panel within the base of the cover, opposite the wastewater inlet, allows the wastewater entering the recovery tank to be guided and buffered by the water-guiding curved panel, while simultaneously falling vertically to the bottom of the recovery tank for collection by raising the liquid level. This prevents the wastewater from directly hitting the multi-stage filtration components or causing turbulent water flow, which could affect the stability of the float components. This achieves the effect of protecting the multi-stage filtration components and improving the structural operational stability.

[0016] Preferably, the water inlet is connected to a retaining ring with a limiting groove. A water inlet cap is inserted into the water inlet, with a handle connected to one end and a locking block connected to the other end. The size of the locking block matches the limiting groove. Water can be quickly added to the clean water tank through the water inlet. The retaining ring is connected to the wall of the water inlet, and the water inlet cap is used to close the water inlet to prevent water from splashing out during movement. After the water inlet cap is inserted into the water inlet, the locking block passes through the limiting groove and rotates, causing the retaining ring to limit the locking block and prevent the water inlet cap from easily falling out. Furthermore, when removing the water inlet cap, simply grasp the handle and rotate it. This improves the stability of the clean water tank and enhances the ease of operation.

[0017] Preferably, both the clean water tank and the recycling cover are equipped with limiting grooves. A handle is rotatably connected to these grooves, and the handle engages with the groove. The limiting grooves also have a clearance groove located near the center of the handle. The water inlet on the end face of the clean water tank is connected to the inside of the tank, and a water cap is inserted into the inlet, allowing the inlet to be opened and closed. The water cap is also quickly secured in the limiting groove via a locking block to prevent it from falling off. Both the clean water tank and the recycling cover have limiting grooves, and the end of the handle rotatably connects to and can be placed within these grooves for storage. The limiting grooves have recessed clearance grooves, allowing fingers to easily grip the handle when operating it, facilitating quick lifting of the clean water tank for adding water or removing the recycling cover for filter maintenance. This improves operational convenience, ease of use, and efficiency of the clean water tank and recycling bin.

[0018] Preferably, the upper part of the machine body is equipped with a connecting rod and a handle. One end of the connecting rod is connected to the machine body, and the other end is connected to the handle. The angle between the handle and the connecting rod is less than 180 degrees. Rollers are rotatably connected to both the left and right sides of the lower part of the machine body. The upper part of the machine body is connected to the handle via the connecting rod, and the lower part is connected to the rollers, allowing the equipment to be easily pushed. At the same time, the handle is non-coaxially connected to the connecting rod at an angle of less than 180 degrees, which facilitates hand grip and force application. The rollers are located on the side of the lower part of the machine body near the upper connecting rod, so that the machine body can be fixed in place when moving and parked, preventing it from rolling away on its own. This improves the convenience and comfort of using the equipment.

[0019] The beneficial effects of this invention are: the use of water through a circulation system facilitates the reduction of burden and improves labor efficiency; saves water resources; improves the practicality and functionality of the equipment; reduces emptying and allows for rapid water output; ensures smooth liquid flow while preventing leakage; provides flexible plug-and-play structure for stable connection and installation and maintenance; improves safety in use; enhances the overall integrity of the equipment; and improves the stability, comfort, and ease of operation of the structure.

One end of the connecting rod 46 is connected to the body 1, and the other end of the connecting rod 46 is connected to the handle 47. The angle between the handle 47 and the connecting rod 46 is less than 180 degrees. Rollers 48 are rotatably connected to the left and right sides of the lower end of the body 1.

[0044] As shown in Figure 1-10: The water passage pipe 18 at the water outlet is connected to the water outlet pipe 50, and the water outlet pipe 50 is connected to the quick-connect connector 3 51. The quick-connect connector 3 51 is inserted into the water pipe 19 so that when water is used, the water stop plug 21 is pushed and water can enter the water outlet pipe 50 and flow from the quick-connect connector 3 51 into the water pipe 19 and then be discharged for use.

[0045] The water pump 5 is screwed onto the water pump mounting base 13 using screws for easy installation and maintenance. The water pump 5 is an electromagnetic pump and can also be a diaphragm pump as the pumping drive. The water pump control switch 8 is electrically connected in series with the water pump 5 and is turned on by placing the clean water tank 2 on the machine body 1. The water pump control switch 8 is started by an external button (not shown in the figure).

[0046] The machine body 1 is connected to a support platform (not shown in the figure) and a suction motor device (not shown in the figure). Because the pipe lengths of the conveying assembly 4 (clean water tank pipe 6 and recovery tank pipe 7) are easily adjustable, the placement of the support platform and suction motor device is more flexible. The support platform is vertically connected to the machine body 1 to support the horizontal placement of the clean water tank 2 and the recovery tank 3 (including horizontal insertion connections with water connector 10 and water connector 11). The suction motor drives the suction of wastewater from the bottom surface. The specific position of the suction motor device is selected according to the suction position of the machine body 1. The opening of the wastewater inlet 17 is the suction port and is connected to the suction motor for use. A positioning post 56 is connected to the lower end face of the clean water tank 2. The support platform is connected to the positioning post 56 through a positioning slot (not shown in the figure) of a suitable size to prevent the clean water tank 2 from slipping off the support platform, thereby improving stability. The entire wastewater recycling system can be used as a separate water supply system or integrated into the overall cleaning equipment as a water-using recycling system.

[0047] In use: After water is used in the clean water tank 2, sewage is sucked from the ground through the suction motor and enters the recycling tank 3 through the sewage inlet 17. The recycling tank 3 collects sewage (air in the recycling tank 3 is discharged through the exhaust pipe 40). The multi-stage filtration assembly filters the sewage. The water pump 5 is started, and the sewage in the recycling tank 3 continuously passes through the foam filter 30, the primary sewage filter 31 and the secondary sewage filter 32 and enters the connecting water pipe 27 at the other end of the pipe connector 33 through the metal filter screen 41. The filtered water enters the clean water tank 2 through the connecting water pipe 27, the recycling tank water pipe 7 and the clean water tank water pipe 6 and is finally discharged from the water pipe 19 for use. During this period, the water valve assembly 49 ensures one-way transportation of circulating water by opening and closing. The above method completes the cycle of water use, recycling, filtration and water use.
