[0034] Reference Figure 1 The embodiments of this application provide a disinfection device for the outer surface of room pipes in an automatic drinking water system, including a disinfectant storage part 1 and a disinfection rod part 2.

[0035] The disinfectant storage section 1 is used to store and pressurize the disinfectant. Specifically, the disinfectant storage section 1 includes a disinfectant storage tank 11, which contains 75% alcohol or chlorine-containing disinfectant with free chlorine of less than 200 ppm. 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 section 2 via a connecting hose 3. Wheels 12 are provided on both sides of the bottom of the disinfectant storage tank 11, and a handle 13 is provided on the top of the disinfectant storage tank 11. This facilitates the transportation of the disinfectant storage tank 11. The sides of the disinfectant storage tank 11 are also provided with buckles 14 for securing the disinfection rod section 2 and winding wheels 15 for winding the connecting hose 3. This facilitates the securing of the disinfection rod section 2 and the winding of the connecting hose 3 during transportation. It should be noted that the disinfectant storage section 1 adopts the structure of an existing pesticide sprayer. For the specific structure, please refer to Chinese Patent "A Hand-Pulled Electric Sprayer" (Publication No.: CN107755120A), which will not be described in detail here.

[0036] Reference Figures 2 to 4 The disinfection rod part 2 includes a wiping assembly 22 and a disinfectant delivery assembly 23. The wiping assembly 22 includes 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 by hinges 222, and each of the two semi-annular grippers 221 is connected to a hinge plate. The inner diameter of the two semi-annular grippers 221 after closing is 2-3 mm larger than the outer diameter of the pipe 4 to be disinfected.

[0037] Reference Figures 5 to 7Both semi-circular grippers 221 have grooves 224, which are U-shaped grooves. Wiping cloths 225 are filled in the grooves 224. Specifically, screws 2212 are provided at the bottom of the U-shaped grooves. The wiping cloths 225 are connected to the grooves 224 by the screws 2212. It should be noted that the top surface of the screws 2212 is lower than the highest point of the groove wall of the groove 224, and the upper surface of the accumulated wiping cloths 225 is higher than the highest point of the groove 224. Therefore, neither the semi-circular grippers 221 nor the screws 2212 will abrade the pipes during the disinfection process.

[0038] Reference Figures 2 to 4 The bottom of the two semi-circular grippers 221 is connected to push rods 226, which can drive the two semi-circular grippers 221 to close or separate. Specifically, the push rods 226 include a vertical push rod 227 and two "L"-shaped push rods 228 disposed on the upper part of the vertical push rod 227. The two "L"-shaped push rods 228 are symmetrically arranged with respect to the axis of the vertical push rod 227. The horizontal section of the "L"-shaped push rod 228 is connected to the vertical push rod 227, and the vertical section of the "L"-shaped push rod 228 is connected to the bottom of the corresponding semi-circular gripper 221. It should be noted that, in order to prevent the "L"-shaped push rods 228 from constricting when the semi-circular 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.

[0039] Reference Figure 1 and Figure 2 The disinfectant delivery assembly 23 includes a disinfectant delivery rigid tube 231, two disinfectant delivery hoses 232, and a switch valve 234 disposed on the disinfectant delivery rigid tube 231. The disinfectant delivery rigid tube 231 may be made of stainless steel. The first end of the disinfectant delivery rigid tube 231 is connected to the outlet of the disinfectant storage section 1 via a connecting hose 3. The second end of the disinfectant delivery rigid tube 231 is connected to the first ends of the two disinfectant delivery hoses 232 respectively, as shown in the figure. Figure 6 The second end of the disinfectant delivery hose 232 is sealed, and multiple disinfectant penetration holes 233 are provided on its side wall. Two disinfectant delivery hoses 232 are respectively fixed in the grooves 224 of the corresponding semi-annular grippers 221 and located below the wiping cloth 225. Specifically, the disinfectant delivery hoses 232 are set on the side wall of the "U"-shaped groove and close to the bottom of the "U"-shaped groove, and the penetration holes on the disinfectant delivery hoses 232 face the wiping cloth 225.

[0040] Reference Figures 2 to 4A handheld sleeve 24 is fitted over the push rod 226 and the disinfectant delivery tube 231. The handheld sleeve 24 is connected to both the hinge pin of the hinge 222 and the disinfectant delivery tube 231, and the handheld sleeve 24 is connected to the hinge pin of the hinge 222 via a connecting plate 27. The push rod 226 can slide up and down within the handheld sleeve 24. Specifically, the length of the handheld sleeve 24 is approximately 1m, ensuring that the gripper can grasp the tube 4 to be disinfected when a person is standing on the ground.

[0041] Reference Figure 8 and Figure 9 The handheld sleeve 24 has vertically extending grooves 241. A limiting slider 229 is fixedly connected to the bottom of the vertical push rod 227. A handle 2210 is provided on the limiting slider 229, extending out of the handheld sleeve 24 after passing through the grooves 241. The limiting slider 229 also has a limiting groove 2211. The handheld sleeve 24 has an upper limiting hole 242 and a lower limiting hole 243. A spring plate 25 connects a pin 26 to the outer wall of the handheld sleeve 24. The pin 26 can pass through the upper limiting hole 242 or the lower limiting hole 243 and insert into the limiting groove 2211. Therefore, when the handle 2210 is pushed upwards 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 downwards to the lower limit position, the push rod 226 can pull the two semi-circular claws 221 to open and lock.

[0042] The switch valve 234 on the disinfectant delivery tube 231 is located below the handheld sleeve 24. To start disinfection, open the switch valve 234; to stop disinfection, close the switch valve 234.

[0043] The working principle of the automatic drinking water system room pipe external surface disinfection device in this application is as follows:

[0044] Before starting disinfection, pull the disinfection device, which is already filled with disinfectant, to the position where disinfection is required. Then, start the pressurization device in the disinfectant storage box 11 to pressurize. Take the disinfection rod part 2 out of the bayonet in the disinfectant storage box 11 and open the switch valve 234 on the disinfectant transmission hard tube 231.

[0045] Holding the hand sleeve 24, push the handle 2210 downward to the lower limit position and lock it with the pin 26. At this time, the push rod 226 pulls the two semi-circular claws 221 open. Raise the hand sleeve 24. After the lowest point inside the semi-circular claw 221 contacts the lowest point of the pipe 4 to be disinfected, pull out the pin 26 and push the handle 2210 upward to the upper limit position and lock it again with the pin 26. At this time, the push rod 226 pushes the two semi-circular claws 221 to close and lock. The wiping cloth 225 inside the semi-circular claw 221 wraps the outer surface of the pipe 4 to be wiped. Since the disinfectant is continuously delivered to the semi-circular claw 221 to wet the wiping cloth 225 through the disinfectant delivery component 23, it is not necessary to frequently remove the wiping cloth 225 to soak it in disinfectant.

[0046] After the disinfection of pipe 4 is completed, close the switch valve 234 on the disinfectant transmission rigid pipe 231, then push the handle 2210 down to the lower limit position and lock it with the pin 26. At this time, the push rod 226 pulls the two semi-circular claws 221 to open, pull down the hand sleeve 24 to keep it away from pipe 4, and then close the pressurization device on the disinfectant storage box 11.

[0047] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
