Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3The utility model provides an embodiment: an automatic pressure regulating water tank-free secondary water supply device, including a delivery pipe 11, a worm 15 is rotatably connected inside the delivery pipe 11, a handle 16 is fixedly connected to the outer wall of the worm 15, a filter 14 is fixedly connected inside the delivery pipe 11, a rotating shaft 17 is rotatably connected inside the filter 14, a brush 19 is fixedly connected to the outer wall of the rotating shaft 17, the outer wall of the brush 19 is fitted with the outer wall of the filter 14, a worm wheel 18 is rotatably connected to the outer wall of the rotating shaft 17, the worm wheel 18 is meshed with the worm 15, and a delivery assembly is provided on the outer wall of the delivery pipe 11;

[0031] Specifically, start the water pump 17 to extract the water inside the water inlet pipe 3 through the suction pipe 9, and transport it to the inside of the delivery pipe 2 11 through the delivery pipe 10. During this process, the tap water will be initially filtered through the filter 14 inside the delivery pipe 2 11 to effectively remove large particles of impurities in the water. When the filter 14 accumulates too many impurities, the staff can turn the handle 16 to drive the worm 15 to rotate. The rotation of the worm 15 further drives the worm wheel 18 and the rotating shaft 17 to rotate, and finally the brush 19 continuously brushes the outer wall of the filter 14 to clean up the accumulated impurities, thereby ensuring the continuous and efficient operation of the filter 14.

[0032] Reference Figure 1-Figure 3 The conveying assembly includes a bilaterally symmetrical conveying pipe 10, the outer wall of which is fixedly connected to the inside of a conveying pipe 2 11, the outer wall of which is fixedly connected to a water pump 7, the input end of which is fixedly connected to a water pumping pipe 9, the outer wall of which is fixedly connected to a water inlet pipe 3, the outer wall of which is fixedly connected to the input end of a water pump 2 8, the output end of which is fixedly connected to the conveying pipe 10, the top end of the water inlet pipe 3 is fixedly connected to a pressure regulating valve 2, the top end of the pressure regulating valve 2 is fixedly connected to a connecting pipe 1, the outer wall of the connecting pipe 1 is fixedly connected to a tap water pipe 12, and both ends of the tap water pipe 12 are fixedly connected to flange plates 13;

[0033] Specifically, when the device needs to be used, the staff first tightly connects the flange plate 13 of the tap water pipe 12 with another tap water pipe 12 to ensure the continuity of the water flow. Then, by starting the controller inside the pressure regulating valve 2, the system realizes the automatic pressure regulation function, thereby preventing the influence of the internal pressure of the tap water pipe 12 after starting the water pump, ensuring that other users can use tap water normally. After the tap water enters the device, start the water pump 17 to pump out the water inside the water inlet pipe 3 through the pumping pipe 9, and transport it to the inside of the delivery pipe 2 11 through the delivery pipe 10.

[0034] Reference Figure 4The outer wall of the delivery pipe 11 is fixedly connected with a fixing plate 4, the lower surface of the fixing plate 4 is fixedly connected with a base 5, the inside of the base 5 is penetrated with a screw hole 6, the outer wall of the delivery pipe 11 is fixedly connected with a filter box 20, the inside of the filter box 20 is slidably connected with an activated carbon plate 21, one side of the activated carbon plate 21 is provided with an RO membrane 22, the outer wall of the RO membrane 22 is slidably connected to the inside of the filter box 20, the upper surfaces of the RO membrane 22 and the activated carbon plate 21 are fixedly connected with a sealing plate 23, the outer wall of the sealing plate 23 is fixedly connected with a connecting plate 24, the upper surface of the connecting plate 24 is fixedly connected with a handle 25, the inside of the filter box 20 is fixedly connected with a water outlet pipe 26, and the inside of the water outlet pipe 26 is provided with a valve 27;

[0035] Specifically, the tap water that has undergone preliminary filtration then enters the interior of the filter box 20, and is filtered again through the activated carbon plate 21 and the RO membrane 22 therein. The activated carbon plate 21 can effectively absorb harmful substances and odors in the water, while the RO membrane 22 can further remove bacteria, viruses and other tiny impurities in the water, thereby significantly improving the quality of the tap water. Finally, the tap water that has undergone secondary filtration is discharged into the outlet pipe 26 by turning the valve 27 for user use. When the activated carbon plate 21 and the RO membrane 22 need to be replaced, the staff can pull the handle 25 to drive the connecting plate 24 and the sealing plate 23 to move. As the sealing plate 23 moves upward, the activated carbon plate 21 and the RO membrane 22 are easily moved out of the interior of the filter box 20, making it convenient for the staff to replace them, thereby ensuring the continuous and stable operation of the entire system.

[0036] Working principle: when the device needs to be used, first connect the flange plate 13 of the tap water pipe 12 to another tap water pipe 12, and then start the controller inside the pressure regulating valve 2 to realize automatic pressure regulation to prevent the pressure inside the tap water pipe 12 from being affected after the water pump is started, which will affect other users' use of tap water. Start the water pump 17 to extract the water inside the water inlet pipe 3 through the pumping pipe 9, and transport it to the inside of the delivery pipe 2 11 through the delivery pipe 10. The tap water is initially filtered through the filter 14 inside the delivery pipe 2 11. When the filter 14 needs to be cleaned, turn the handle 16 to rotate the worm 15, and the rotation of the worm 15 drives the worm wheel 18 and the rotating shaft 17 to rotate. The rotating shaft 17 The rotation of the brush 19 continuously brushes the outer wall of the filter 14 to prevent impurities in the water from clogging the filter 14. The filtered tap water is then discharged into the interior of the filter box 20 through the delivery pipe 11, and is filtered again through the activated carbon plate 21 and the RO membrane 22 inside the filter box 20 to improve the quality of the tap water. Finally, the valve 27 is turned to discharge the tap water through the outlet pipe 26. When it is necessary to replace the activated carbon plate 21 and the RO membrane 22, the handle 25 is pulled to move the connecting plate 24 and the sealing plate 23, and the sealing plate 23 is moved upward to move the activated carbon plate 21 and the RO membrane 22 out of the filter box 20, thereby replacing the activated carbon plate 21 and the RO membrane 22.
