Description

Technical Field

[0001] The present invention relates to the technical field of household floor washing machines, and specifically to a household floor washing machine capable of recycling and reusing wastewater. Background Art

[0002] With the rapid development of technology and the improvement of people's living standards, people's requirements for the quality of life are also constantly increasing. Correspondingly, the requirements for environmental hygiene are getting higher and higher. However, the work pressure of modern people is increasing day by day, and there is an urgent need to be liberated from the heavy cleaning work. Therefore, many floor cleaning devices have emerged to improve environmental hygiene. Commonly used ones include vacuum cleaners, automatic mop machines, sweepers, and automatic floor washing machines. When using a vacuum cleaner and an automatic mop machine to clean the floor, it is necessary to manually vacuum first and then mop. The automatic mop machine is very effective in cleaning dirt on the floor. However, if the floor is too dirty, the mop needs to be continuously rinsed to ensure that the floor is mopped clean. In this way, the efficiency is relatively low, the labor intensity is large, and the work is cumbersome. The functions of these cleaning tools are relatively single, so the status of the automatic floor washing machine in the category of floor cleaners has been rapidly improved.

[0003] A large amount of wastewater will be generated during the use of a floor washing machine. If directly discharged, it will not only cause waste of water resources, but also may have a certain impact on the environment. Therefore, traditional household floor washing machines mainly supply water through a clean water tank for floor cleaning and collect the used sewage in a sewage tank. This method has problems such as insufficient battery life, large body weight, and large volumes of the clean water tank and the sewage tank. For example, the household floor washing machine disclosed in the authorized publication number CN213993458U includes a floor washing machine main body and a floor brush; a rolling brush is provided inside the floor brush; a water tank and a sewage tank are provided on the floor washing machine main body; a controller, a liquid spraying device, a rolling brush motor for controlling the rolling brush, a suction device, and a main machine motor for controlling the suction device are also provided; the liquid spraying device, the rolling brush motor, and the main machine motor are respectively electrically connected to the controller; in this technical solution, the operation of the water tank is to supply water to the liquid spraying device; the sewage tank is used to collect sewage. During operation, the liquid spraying device is in an open state to spray liquid on the rolling brush; the rolling brush motor is in an open state to rotate the rolling brush; the main machine motor is in an open state to suck the sewage flowing through the rolling brush into the liquid suction pipeline and finally flow into the sewage tank. However, the applicant found that the wastewater in the existing sewage tank cannot be recycled, resulting in the need to equip a large-capacity sewage tank and cleaning water to improve the battery life of the existing household floor washing machine. This not only increases the weight of the floor washing machine, but also limits its portability and use flexibility. Summary of the Invention

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Referring to Figures 1-6 , the present invention provides the following two technical solutions:

[0029] The first implementation method: A household floor washer capable of recycling wastewater, including a cleaning component 1. The cleaning component 1 includes a detachable cleaning brush, a spraying device, and a water suction rake. The cleaning brush can efficiently remove stains on the ground and at the same time spray an appropriate amount of cleaning water to improve the cleaning effect. The water suction rake is externally connected to a hose 10 to suck the sewage after brushing into the sewage tank 8. The spraying device is externally connected to two hoses 42 for spraying cleaning water;

[0030] The cleaning component 1 is connected to two mounting rods 2 through a pin shaft. Both of the two mounting rods 2 are connected to the control system 3. A control panel 4 electrically connected to the control system 3 is provided at the top of the control system 3, and the control panel 4 is convenient for users to operate;

[0031] Both of the two mounting rods 2 are connected to the sewage tank 8. A slant pipe 9 is communicated with the left bottom of the sewage tank 8. The slant pipe 9 prevents impurities in the sewage tank 8 from flowing back. A hose 10 connected to the cleaning component 1 is connected to the slant pipe 9. A sewage pump 11 is communicated with the top of the sewage tank 8. A water delivery pipe 12 communicated with the clean water tank assembly is provided on the sewage pump 11, and the clean water tank assembly is communicated with the cleaning component 1;

[0032] A purification component is provided in the sewage tank 8.

[0033] A turbidity sensor 13 is provided in the sewage tank 8, and the turbidity sensor 13 is electrically connected to the control system 3. The control system 3 is electrically connected to the sewage pump 11. By setting the turbidity sensor 13, the turbidity of the sewage in the sewage tank 8 can be detected, so as to control the opening frequency of the sewage pump 11 through the control system 3. When the sewage turbidity is high, the opening frequency of the sewage pump 11 is increased to facilitate the rapid treatment of sewage.

[0034] The purification component includes a coarse filtration component, a fine filtration component, an activated carbon layer 30, and an electrolyzed water sterilization device 31 which are sequentially arranged from bottom to top in the sewage tank 8. The sewage pump 11 is communicated with the water outlet of the electrolyzed water sterilization device 31. The activated carbon layer 30 removes impurities such as organic matters, odors, and pigments in the wastewater. In the final stage of the sewage purification process, the electrolyzed water sterilization technology is adopted. Through bactericidal substances such as hypochlorous acid generated by electrolyzed water, bacteria, viruses and other microorganisms in the wastewater are effectively killed to ensure that the purified water quality meets the reuse standard.

[0035] The coarse filtration component includes a coarse filtration plate 14 located above the inclined tube 9 and attached to the inner wall of the sewage tank 8. It uses a grid plate and a filter cloth bag to remove large particulate impurities and suspended solids in the wastewater. Guide rods 18 are evenly arranged circumferentially at the top of the coarse filtration plate 14. The tops of the guide rods 18 are slidably connected within guide cylinders 16. The tops of the guide cylinders 16 are all connected to a mounting ring 15 provided on the inner wall of the sewage tank 8. And a first spring 17 connected to the guide rod 18 is provided at the bottom of the mounting ring 15. The bottom inner wall of the sewage tank 8 is attached and connected to a collecting hopper 19. And the bottom end of the collecting hopper 19 penetrates through the sewage tank 8 and is connected to a sealing cover 20. A vertical rod 21 penetrating through the sewage tank 8 is provided on the collecting hopper 19. And a bottom block 22 is provided at the bottom of the vertical rod 21. A second spring 23 connecting the bottom block 22 to the bottom of the sewage tank 8 is provided at the top of the bottom block 22. By reciprocally moving the collecting hopper 19 up and down, the second spring 23 can be telescoped to strike the coarse filtration plate 14, enabling the coarse filtration plate 14 to reciprocally lift and lower through the first spring 17, so as to shake off the impurities at the bottom of the coarse filtration plate 14 and discharge them into the collecting hopper 19, thereby enabling the cleaning of the impurities on the coarse filtration plate 14 from the outside. When the wastewater after purification and treatment is recycled multiple times and its water quality fails to meet the cleaning requirements, it can be discharged by opening the sealing cover 20.

[0036] The fine filtration component includes a fixed ring 24 provided on the inner wall of the sewage tank 8. A fine filtration core 25 is provided on the fixed ring 24. It uses a ceramic water treatment membrane as the fine filtration material to further remove fine particles and impurities in the wastewater and ensure that the purified water quality meets the reuse standard. Two annular pipes 26 with different heights are provided on the inner wall of the sewage tank 8. And nozzles 27 opposite to the fine filtration core 25 are provided on the inner walls of the annular pipes 26. Connecting pipes 28 successively penetrating through the sewage tank 8 and the mounting rod 2 are provided on both annular pipes 26. A first valve 29 electrically connected to the control system 3 is provided on the connecting pipe 28.

[0037] An installation cover 32 is provided at the top of the sewage tank 8. A second turbidity sensor 33 extending into the water supply pipe 12 is provided on the installation cover 32. And the second turbidity sensor 33 is electrically connected to the control system 3. A recovery pipe 34 communicating with the sewage tank 8 is connected to the water supply pipe 12. And a second valve 35 is provided on the water supply pipe 12. A third valve 36 is provided on the recovery pipe 34. Both the second valve 35 and the third valve 36 are electrically connected to the control system 3. The second turbidity sensor 33 can detect the water quality after purification. When it is found that the water quality is poor, the second valve 35 is closed through the control system 3 to prevent the poor water quality from entering the water tank 37. The third valve 36 is opened to enable the water body with poor water quality to return to the sewage tank 8 through the recovery pipe 34 and be purified again through the purification component. When it is found that the water quality after purification has been poor all the time, the purification component can be inspected to check whether there is any damage.

[0038] The fresh water tank assembly includes a fresh water tank 37 that is connected to the water supply pipe 12 and is disposed on the control system 3. A water level sensor 38, a water filling port 39, and a fresh water pump 40 are provided on the fresh water tank 37, which can monitor the water level of the fresh water tank 37 in real time. When the water level is too low, the user is prompted to replenish fresh water to ensure that the floor washer can continue to perform the cleaning work. Two drain pipes 41 are provided on the fresh water pump 40, and a second hose 42 connected to the cleaning assembly 1 is provided on the drain pipe 41. The drain pipe 41 is connected to the connecting pipe 28, and a fourth valve 43 electrically connected to the control system 3 is provided on the drain pipe 41. When the water filtration efficiency becomes small, that is, when the fine filter element 25 is blocked, the cleaning process can be executed to prevent the decline of the membrane filtration flux. Close the fourth valve 43 and open the first valve 29, so that the fresh water pump 40 pumps out fresh water, so that the connecting pipe 28 sends water into the annular pipe 26, and then the fine filter element 25 is flushed through the nozzle 27 to remove the impurities on the outside of the fine filter element 25. When water needs to be supplied to the spraying device, close the first valve 29 and open the fourth valve 43.

[0039] The second implementation mode is mainly different from the first implementation mode in that: a telescopic rod 5 is provided on the fresh water tank 37, a handle 6 is provided on the telescopic rod 5, and a main power switch 7 is provided on the handle 6, which is convenient for users to use.

[0040] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0041] During use, the sewage enters the sewage tank 8 through the first hose 10 and the inclined pipe 9, and then is filtered and purified through the coarse filter plate 14, the fine filter element 25, the activated carbon layer 30, and the electrolyzed water sterilization device 31, and then is detected by the second turbidity sensor 33. After the water quality meets the requirements for reuse, it is sent into the fresh water tank 37 for recycling.
