Detailed implementation manners

[0031] 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 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.

[0033] It should be noted that when the water storage tank body 1 is placed into the base station of the cleaning robot, the sewage inlet pipe 3 and the clean water outlet pipe 4 at the bottom of the water storage tank body 1 will correspond to the interfaces in the base station of the cleaning robot;

[0034] The inner wall of the water storage tank body 1 is connected with a guide rod 6, the inner wall of the water storage tank body 1 is connected with a stopper 7, the top of the sewage inlet pipe 3 is threadedly connected with a threaded joint 8, one end of the threaded joint 8 is connected with a soft sewage storage water bag 9, the top of the soft sewage storage water bag 9 is connected with a sewage discharge pipe 10, and the outer wall of the sewage discharge pipe 10 is threadedly connected with a sealing cover 11;

[0035] It should be noted that a buckle is installed on the outer wall of the tank cover 2, and a corresponding clamping groove is arranged on the outer wall of the water storage tank body 1, so as to realize clamping after the tank cover 2 is closed;

[0036] It should be noted that one-way valves are installed at one ends of the sewage inlet pipe 3 and the clean water outlet pipe 4. The one-way valve installed in the clean water outlet pipe 4 can only convey the clean water in the tank outwards, while the one-way valve installed in the sewage inlet pipe 3 can only send the sewage generated by the cleaning robot into the soft sewage storage water bag 9 in the water storage tank body 1.

[0037] Preferably: The soft sewage storage water bag 9 is made of polyvinyl chloride. The outside of the partition plate 5 is sleeved on the outer wall of the guide rod 6, and the partition plate 5 can form a sliding connection structure with the water storage tank body 1 through the guide rod 6;

[0038] It should be noted that the soft sewage storage water bag 9 made of polyvinyl chloride has good flexibility and corrosion resistance, and can be made into water storage containers of various shapes and sizes. The stop block 7 is used to limit the sliding position of the partition plate 5.

[0039] In specific use, by setting the soft sewage storage water bag 9 made of polyvinyl chloride and connecting it to the sewage inlet pipe 3, at this time the soft sewage storage water bag 9 is in a deflated state. At this time, the user can pour a whole box of clean water into the water storage tank body 1. When the clean water is pumped out by the cleaning robot and becomes sewage, the sewage will be conveyed from the sewage inlet pipe 3 into the soft sewage storage water bag 9. And as the sewage is continuously conveyed, the soft sewage storage water bag 9 made of polyvinyl chloride will expand, and the expanded soft sewage storage water bag 9 will simultaneously push the partition plate 5 to move along the guide rod 6. Thus, in this way, more clean water can be accommodated without changing the volume of the water storage tank body 1, and further reduce the frequency of changing water in the water storage tank when the user uses the cleaning robot;

[0040] It should be noted that by pinching the connection end of the soft sewage storage water bag 9 and the threaded joint 8 and rotating counterclockwise, the soft sewage storage water bag 9 can be detached, and by unscrewing the sealing cover 11, both ends of the soft sewage storage water bag 9 can be made to communicate with water. When cleaning the inside of the soft sewage storage water bag 9, water is poured in from one end, and sewage will be discharged from the other end.

[0041] Preferably: Grooves 12 are provided on the outer walls on both sides of the water storage tank body 1. The inner walls of the grooves 12 are connected with transparent tubes 13.

A floating ball 15 is arranged inside the transparent tube 13. One end of the connecting tube 14 far from the transparent tube 13 is threadedly connected with a connecting cover 17. A filter screen 18 is arranged at one end of the connecting cover 17. The interiors of the water storage tank body 1, the transparent tube 13 and the connecting tube 14 are connected and communicated with each other.

[0042] During specific use, transparent tubes 13 are arranged on both sides of the water storage tank body 1. When water enters the separated sewage tank and clean water tank, a part of the water will enter the transparent tube 13 through the connecting pipe 14. At this time, the floating ball 15 inside the transparent tube 13 will float under the action of water. The user can view the position where the floating ball 15 stays through the transparent tube 13, and then cooperate with the scale 16 on the outer wall, the user can clearly check the retention amount of clean water or sewage inside, which is beneficial for the user to add clean water or treat sewage in time;

[0043] One end of the connecting pipe 14 is threadedly connected with a connecting cover 17, and then the filter screen 18 at the end of the connecting cover 17 can filter the water entering the transparent tube 13, so as to prevent impurities from adhering to the inner wall of the transparent tube 13;

[0044] It should be noted that the gap between the inner wall of the groove 12 and the transparent tube 13 is bonded with polyvinyl chloride glue. Polyurethane glue has high bonding strength, especially good adhesion to various materials such as metals and plastics. At the same time, it has excellent water resistance and wear resistance and performs well in humid and possibly friction environments. The outer wall of the transparent tube 13 is provided with air holes for discharging the excess gas in the tube when water enters the inside of the transparent tube 13.

[0045] Preferably: a rectangular frame 19 is arranged at the top of the clean water outlet pipe 4, a filter plate 20 is arranged inside the rectangular frame 19, two fixing blocks 21 are respectively connected to both sides of the filter plate 20, four positioning grooves 23 are opened at the top of the rectangular frame 19, and one end of the fixing block 21 is located inside the positioning groove 23.

[0046] During specific use, the movable block 26 is driven by the dialing block to drive the expansion pin 27 to contract, and then the filter plate 20 is placed inside the rectangular frame 19, and the fixing blocks 21 on both sides are located in the positioning grooves 23. At this time, the dialing block is released, and the expansion pin 27 will pop out under the action of the spring 25 and insert into the card slot 22 at the end of the fixing block 21, so that the water sent out by the clean water outlet pipe 4 can be filtered by the filter plate 20.

[0047] Preferably: card slots 22 are opened on the outer walls of the two fixing blocks 21, two mounting seats 24 are symmetrically distributed on both sides of the rectangular frame 19, springs 25 are arranged inside the two mounting seats 24, the ends of the springs 25 are connected with a movable block 26, one end of the movable block 26 is connected with an expansion pin 27, and the filter plate 20 can form an elastic clamping structure with the rectangular frame 19 through the fixing blocks 21, card slots 22, positioning grooves 23, mounting seats 24, springs 25, movable blocks 26, and expansion pins 27.

[0048] During specific use, the movable block 26 is driven by the dialing block to drive the pin 27 to contract. At this time, one end of the pin 27 will disengage from the positioning groove 23, and then the filter plate 20 can be removed by lifting it upward, facilitating subsequent cleaning of the filter plate 20 and preventing it from being blocked.

[0049] Working principle of implementation: First, by setting up the soft sewage storage water bag 9 made of polyvinyl chloride and connecting it to the sewage inlet pipe 3. At this time, the soft sewage storage water bag 9 is in a deflated state. The user can introduce a whole box of clean water into the water storage tank body 1. When the clean water is pumped out by the cleaning robot and becomes sewage, the sewage will be transported from the sewage inlet pipe 3 into the soft sewage storage water bag 9. And as the sewage is continuously transported, the soft sewage storage water bag 9 made of polyvinyl chloride will expand. And the expanded soft sewage storage water bag 9 will simultaneously push the partition plate 5 to move along the guide rod 6. Thus, in this way, more clean water can be accommodated without changing the volume of the water storage tank body 1, thereby reducing the frequency of changing water in the water storage tank when the user uses the cleaning robot. By setting transparent tubes 13 on both sides of the water storage tank body 1, when water enters the separated sewage tank and clean water tank, a part of the water will enter the transparent tube 13 through the connecting pipe 14. At this time, the floating ball 15 inside the transparent tube 13 will float under the action of the water. The user can view the position where the floating ball 15 stays through the transparent tube 13, and then cooperate with the scale 16 on the outer wall, the user can clearly check the remaining amount of clean water or sewage inside, which is beneficial for the user to add clean water or treat sewage in time. And by threadedly connecting a connection cover 17 at one end of the connecting pipe 14, and using the filter screen 18 at the end of the connection cover 17, the water entering the transparent tube 13 can be filtered, thus preventing impurities from adhering to the inner wall of the transparent tube 13. The movable block 26 is driven by the dialing block to drive the pin 27 to contract, and then the filter plate 20 is placed inside the rectangular frame 19, and the fixing blocks 21 on both sides are located in the positioning grooves 23. At this time, when the dialing block is released, the pin 27 will pop out under the action of the spring 25 and insert into the card slot 22 at the end of the fixing block 21. Thus, the water sent out by the clean water outlet pipe 4 can be filtered by the filter plate 20.

[0050] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
