[0035] 1 , an embodiment of the present application provides a device for disinfecting the outer surface of a room pipeline in an automatic drinking water system, comprising a disinfectant storage portion 1 and a disinfection rod portion 2 .

[0036] The disinfectant storage unit 1 is used to store and pressurize disinfectant. Specifically, the disinfectant storage unit 1 includes a disinfectant storage tank 11, which contains 75% alcohol or a chlorine-containing disinfectant with less than 200 ppm free chlorine. Any unused disinfectant can be discharged from the bottom of the disinfectant storage tank 11. The outlet of the disinfectant storage tank 11 is connected to the disinfection rod 2 via a connecting hose 3. Wheels 12 are located on both sides of the bottom of the disinfectant storage tank 11, and a handle 13 is located on the top. This facilitates transportation of the disinfectant storage tank 11. The sides of the disinfectant storage tank 11 also feature a buckle 14 for securing the disinfection rod 2 and a reel 15 for winding the connecting hose 3.

It should be noted that the disinfectant storage unit 1 adopts the structure of existing pesticide sprayers. For details, see Chinese Patent Application "A Hand-Pull Electric Sprayer" (Publication No.: CN107755120A) and will not be described in detail here.

[0037] Referring to Figures 2 to 4 , the disinfection rod 2 includes a wiper assembly 22 and a disinfectant delivery assembly 23. The wiper assembly 22 comprises two semi-annular grippers 221 hinged at their bottom ends and a push rod 226. Specifically, the bottoms of the two semi-annular grippers 221 are hinged via hinges 222, each connected to a hinge piece. The inner diameter of the two semi-annular grippers 221 when closed is 2-3 mm larger than the outer diameter of the pipe 4 to be disinfected.

[0038] 5 to 7 , a groove 224 is provided in each of the two semi-circular grippers 221 . The groove 224 is a U-shaped groove, and the groove 224 is filled with a wiping cloth 225 . Specifically, a screw 226 is provided at the bottom of the U-shaped groove, and the wiping cloth 225 is connected to the groove 224 through the screw 226 . It should be noted that the top surface of the screw 226 is lower than the highest point of the groove wall of the groove 224 , and the upper surface of the accumulated wiping cloth 225 is higher than the highest point of the groove 224 . Therefore, the semi-circular grippers 221 and the screw 226 will not grind the pipe during the disinfection process.

[0039] Referring to Figures 2 to 4 , the bottoms of the two semi-annular grippers 221 are connected to push rods 226, which can drive the two semi-annular grippers 221 to close or open. Specifically, the push rods 226 include a vertical push rod 227 and two L-shaped push rods 228 disposed above the vertical push rod 227. The two L-shaped push rods 228 are positioned symmetrically about the axis of the vertical push rod 227. The horizontal sections of the L-shaped push rods 228 are connected to the vertical push rod 227, and the vertical sections of the L-shaped push rods 228 are connected to the bottoms of the corresponding semi-annular grippers 221. It should be noted that to prevent the L-shaped push rods 228 from stagnating when the semi-annular grippers 221 swing, the horizontal and vertical sections of the L-shaped push rods 228 can swing at a small angle, and the L-shaped push rods 228 can also be slightly deformed and bent.

[0040] Referring to Figures 1 and 2, the disinfectant transmission assembly 23 includes a disinfectant transmission rigid tube 231, two disinfectant transmission hoses 232, and an on-off valve 234 disposed on the disinfectant transmission rigid tube 231. The disinfectant transmission rigid tube 231 can be made of stainless steel. The first end of the disinfectant transmission rigid tube 231 is connected to the outlet of the disinfectant storage portion 1 via a connecting hose 3. The second end of the disinfectant transmission rigid tube 231 is connected to the first end of each of the two disinfectant transmission hoses 232. Referring to Figure 6, the second ends of the disinfectant transmission hoses 232 are blocked, and their sidewalls are provided with multiple disinfectant permeation holes 233. The two disinfectant transmission hoses 232 are respectively fixedly connected to the grooves 224 of the corresponding semi-annular grippers 221 and are located below the wiping cloth 225. Specifically, the disinfectant transmission hoses 232 are disposed on the sidewalls of the U-shaped groove and near the bottom of the U-shaped groove, with the seepage holes in the disinfectant transmission hoses 232 facing the wiping cloth 225.

[0041] Referring to Figures 2 to 4 , a hand-held sleeve 24 is sheathed around the push rod 226 and the disinfectant delivery tube 231. The hand-held sleeve 24 is connected to both the hinge axis of the hinge 222 and the disinfectant delivery tube 231. The hand-held sleeve 24 and the hinge axis of the hinge 222 are connected via a connecting plate 27. The push rod 226 can slide up and down within the hand-held sleeve 24. Specifically, the hand-held sleeve 24 is approximately 1 meter long, sufficient to ensure that a person standing on the ground can grasp the pipe 4 to be disinfected.

[0042] 8 and 9 , the hand-held sleeve 24 is provided with a vertically extending slot 241. The bottom of the vertical push rod 227 is fixedly connected to a limit slider 229. The limit slider 229 is provided with a handle 2210, which passes through the slot 241 and extends out of the hand-held sleeve 24. The limit slider 229 is also provided with a limit slot 2211. The hand-held sleeve 24 is provided with an upper limit hole 242 and a lower limit hole 243. A latch 26 is connected to the outer wall of the hand-held sleeve 24 via a spring plate 25. The latch 26 can pass through either the upper limit hole 242 or the lower limit hole 243 and then be inserted into the limit slot 2211. Therefore, when the handle 2210 is pushed upward to the upper limit position, the push rod 226 can push the two semi-circular claws 221 to close and lock. When the handle 2210 is pulled downward to the lower limit position, the push rod 226 can pull the two semi-circular claws 221 to open and lock.

[0043] The switch valve 234 on the disinfectant transmission hard tube 231 is located below the handheld sleeve 24. When disinfection needs to be started, the switch valve 234 is opened, and when disinfection needs to be stopped, the switch valve 234 is closed.

[0044] The working principle of the external surface disinfection device of the automatic drinking water system room pipe in the embodiment of the present application is as follows:

[0045] Before starting disinfection, first pull the disinfection device filled with disinfectant to the position where disinfection is required, then start the pressurizing device in the disinfectant storage box 11 to start pressurizing, remove the disinfection rod part 2 from the bayonet of the disinfectant storage box 11, and open the switch valve 234 on the disinfectant transmission hard pipe 231.

[0046] Hold the handheld sleeve 24, push the handle 2210 downward to the lower limit position and lock it through the latch 26. At this time, the push rod 226 pulls the two semi-annular claws 221 to open, lift the handheld sleeve 24, and after the lowest point inside the semi-annular claw 221 contacts the lowest point of the pipe 4 to be disinfected, pull out the latch 26 and push the handle 2210 upward to the upper limit position and lock it again through the latch 26. At this time, the push rod 226 pushes the two semi-annular claws 221 to close and lock, and the wiping cloth 225 in the semi-annular claw 221 wraps the outer surface of the pipe 4 to be wiped. Since the disinfectant is continuously transported to the semi-annular claw 221 through the disinfectant transmission component 23 to soak the wiping cloth 225, there is no need to frequently remove the wiping cloth 225 to soak the disinfectant.

[0047] After the pipeline 4 is completely disinfected, close the switch valve 234 on the disinfectant transmission hard pipe 231, and then push the handle 2210 downward to the lower limit position and lock it through the pin 26. At this time, the push rod 226 pulls the two semi-annular claws 221 to open, pulls down the handheld sleeve 24 to keep it away from the pipeline 4, and then closes the pressurizing device on the disinfectant storage box 11.

[0048] The above are only specific embodiments of the present application, but the scope of protection of the present application is not limited thereto. Any changes or replacements within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
