[0016] Compared with the prior art, the present invention provides an automatic drug adding and disinfection device for a secondary water supply pump room, which has the following beneficial effects:

[0017] 1. The automatic dosing and disinfection device for a secondary water supply pump room is provided with a premixing tank, a hanging ring, a C-type tube and a spoiler ring. Tap water is introduced into the interior of the mixing tank through a water inlet pipe, and disinfectant solution is introduced into the mixing tank through a first dosing pipe. The tap water and the disinfectant solution first flow into the premixing tank and are fully mixed in the premixing tank until the storage capacity of the premixing tank is saturated. At this time, the tap water and the disinfectant solution continue to flow into the premixing tank, so the mixed water inside the premixing tank overflows from the tank mouth, flows from the middle of the hanging ring to the edge, and then flows into the C-type tube, and falls from the tube mouth of the C-type tube to the spoiler ring on the outer wall of the premixing tank. The complexity of the water flow path is increased by the spoiler ring. Without using external driving force and transmission machinery, the mixing of tap water and disinfectant water is promoted by changing the water flow path, thereby optimizing the mixing effect, avoiding the pollution of water source by debris generated by the wear of mechanical parts due to long-term continuous operation, and having low water pressure requirements for water supply, and no water flow is required to provide driving force for parts, thereby realizing low-energy disinfection.

[0018] 2. This automatic dosing and disinfection device for a secondary water supply pump room is provided with a conducting pipe, a closing plug, a sealing ring, an expanding ring and a spring. After the water supply of the water inlet pipe and the first dosing pipe is disconnected, the lifting pipe can be pulled upward, and the closing plug is driven upward to separate from the conducting pipe through the sleeve, connecting rod, push rod, bottom plate and extension rod, and the remaining water in the premixing tank is actively discharged through the conducting pipe. The sleeve and the second bellows form an isolation on the outside of the lifting pipe to prevent the movement of the lifting pipe from polluting the premixing tank. The second bellows can be retracted and extended to adapt to the adjustment of the lifting pipe. When the lifting pipe is pulled, the pressure ring and the bottom plate jointly compress the spring. After the active drainage is completed, the lifting pipe is released, and the compressed spring pushes the lifting pipe and the closing plug to automatically reset. The sealing ring optimizes the closing effect of the closing plug on the conducting pipe. The expanding ring cannot enter the conducting pipe, which limits the insertion depth of the closing plug in the conducting pipe for easy positioning.

[0019] 3. This automatic dosing and disinfection device for a secondary water supply pump room is equipped with a handle, a guide rail and a slot. When the premix tank is actively drained, the handle needs to be pulled up. At this time, the spring is in a compressed state, and the handle can be rotated to deflect into the guide rail, slide along the slide groove in the guide rail, and fall into the slot. In this way, the height of the handle is positioned, and there is no need for the staff to manually resist the spring to maintain the height of the handle. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In the present invention, two symmetrically distributed pull rings 17 are fixedly connected to the top of the tank cover 4, and two symmetrically distributed lock buckles 5 are fixedly connected between the outer wall of the tank cover 4 and the outer wall of the medicine mixing tank 1. The tank cover 4 is locked above the medicine mixing tank 1 by the lock buckles 5. After unlocking, the tank cover 4 and the premixing tank 18 below can be pulled out of the medicine mixing tank 1 by the pull ring 17.

[0031] In the present invention, the pipe opening at the bottom of the first dosing pipe 7 is located above the top opening of the premixing tank 18, and the pipe opening at the bottom of the lifting pipe 31 is located below the premixing tank 18, ensuring that the disinfectant water added through the first dosing pipe 7 enters the premixing tank 18, and the disinfectant water added through the second dosing pipe 11 and the lifting pipe 31 directly reaches the bottom space of the mixing tank 1.

[0032] In the present invention, the inner wall circumference of the top of the medicine mixing tank 1 is fixedly connected with evenly distributed support blocks 19, the tops of the support blocks 19 are all in contact with the bottom of the hanging ring 21, the middle of the support blocks 19 are provided with pin holes, and the bottom of the hanging ring 21 is fixedly connected with evenly distributed positioning pins 20, the positioning pins 20 correspond one-to-one to the pin holes of the support blocks 19, the hanging ring 21 and the premixing tank 18 are supported inside the medicine mixing tank 1 by the support blocks 19, and the positioning pins 20 are inserted into the pin holes of the support blocks 19, so as to further enhance the stability of the hanging ring 21 and the premixing tank 18.

[0033] In the present invention, a sealing ring 35 is sleeved in the middle of the closing plug 34, and an expanding ring 36 is fixedly connected to the middle outer wall of the sealing ring 35. The outer diameter of the expanding ring 36 is larger than the inner diameter of the conducting tube 24, and the bottom of the expanding ring 36 fits against the top of the conducting tube 24. The sealing ring 35 optimizes the closing effect of the closing plug 34 on the conducting tube 24. The expanding ring 36 cannot enter the conducting tube 24, which limits the insertion depth of the closing plug 34 in the conducting tube 24 and facilitates positioning.

[0034] In the present invention, a pressure ring 33 is fixedly connected to the circumference of the inner wall of the conducting tube 24, a through hole is opened in the middle of the pressure ring 33, the extension rod 32 passes through the through hole in the middle of the pressure ring 33, the top of the pressure ring 33 contacts the bottom of the closing plug 34, and a spring 37 is fixedly connected between the pressure ring 33 and the bottom plate 25. When the lifting tube 31 is pulled, the pressure ring 33 and the bottom plate 25 jointly compress the spring 37. After the active drainage is completed, the lifting tube 31 is released, and the compressed spring 37 pushes the lifting tube 31 and the closing plug 34 to automatically reset.

[0035] In the present invention, the outer diameter of the bottom plate 25 is smaller than the inner diameter of the conducting tube 24, and the outer diameter of the extension rod 32 is smaller than the inner diameter of the middle through hole of the pressure ring 33. After the closing plug 34 leaves the conducting tube 24, the bottom plate 25 will not block the conducting tube 24, and the extension rod 32 will not block the pressure ring 33, thereby ensuring smooth drainage.

[0036] In the present invention, the same first corrugated tube 10 is fixedly connected between the lifting tube 31 and the second dosing tube 11, and a connecting piece 38 is fixedly connected to the circumference of the bottom outer wall of the second dosing tube 11. A vertically arranged support rod 12 is fixedly connected to the side of the connecting piece 38 away from the second dosing tube 11. The support rod 12 is fixedly connected to the top of the tank cover 4. The second dosing tube 11 above the first corrugated tube 10 is fixedly supported by the support rod 12 and the connecting piece 38. The first corrugated tube 10 can be extended and retracted to ensure that the lifting tube 31 can achieve longitudinal displacement while being connected to the second dosing tube 11.

[0037] In the present invention, the rod body of the support rod 12 is slidably connected with a slider 13, the limiting ring 9 is fixedly connected to the slider 13, and the side of the slider 13 away from the limiting ring 9 is fixedly connected with a handle 14. By pulling the slider 13 along the rod body of the support rod 12 through the handle 14, the limiting ring 9 and the lifting tube 31 can be driven to move.

[0038] In the present invention, the top of the handle 14 is rotatably connected to the turning handle 15, and the top of the support rod 12 is fixedly connected to the guide rail 16. A slide groove is provided inside the guide rail 16, one end of the slide groove is set as an opening, and the middle position of the bottom of the slide groove is set as a card slot 39. When the premix tank 18 is actively drained, the handle 14 needs to be pulled up. At this time, the spring 37 is in a compressed state, and the turning handle 15 can be rotated to deflect the turning handle 15 into the guide rail 16, slide along the slide groove in the guide rail 16, and fall into the card slot 39, so that the height of the handle 14 is positioned, and there is no need for the staff to manually resist the spring 37 to maintain the height of the handle 14.

[0039] When in use, the tank cover 4 is closed on the top of the medicine mixing tank 1, tap water is introduced into the medicine mixing tank 1 through the water inlet pipe 6, and disinfectant is introduced into the medicine mixing tank 1 through the first dosing pipe 7. The tap water and the disinfectant first flow into the premixing tank 18 and are fully mixed in the premixing tank 18 until the storage of the premixing tank 18 is saturated. At this time, the tap water and the disinfectant continue to flow into the premixing tank 18, so the mixed water inside it overflows from the tank mouth, flows from the middle of the hanging ring 21 to the edge, and then flows into the C-type tube 23, and falls from the pipe mouth of the C-type tube 23 to the spoiler ring 22 on the outer wall of the premixing tank 18. The spoiler ring 22 increases the complexity of the water flow path and optimizes the mixing effect. The tap water mixed with the disinfectant continues to flow downward after passing through the spoiler ring 22 and enters the bottom of the medicine mixing tank 1. When it is necessary to disinfect tap water multiple times and add disinfectant water in sequence, subsequent disinfectant water can be introduced into the bottom of the mixing tank 1 through the second dosing pipe 11, and the water after the initial disinfection can be disinfected again and enter the subsequent process through the outlet pipe 3. After the water supply of the water inlet pipe 6 and the first dosing pipe 7 is disconnected, the lifting pipe 31 can be pulled upward, and the closing plug 34 can be driven upward to separate from the conducting pipe 24 through the ring 28, the connecting rod 27, the push rod 26, the bottom plate 25, and the extension rod 32. The remaining water in the premixing tank 18 is actively discharged through the conducting pipe 24. The sleeve 8 and the second bellows 29 form an isolation on the outside of the lifting pipe 31 to prevent the movement of the lifting pipe 31 from causing pollution to the premixing tank 18. The second bellows 29 can be extended and retracted to adapt to the adjustment of the lifting pipe 31.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
