Description

Technical Field

[0001] The invention relates to the technical field of high-pressure water jet cleaning, and in particular to a full-automatic toilet cleaning device. Background Art

[0002] At present, the traditional squat toilet cleaning is usually manual cleaning, which is done manually by flushing, mopping, and brushing the inner wall of the squat toilet to achieve the cleaning effect. However, manual cleaning has too many limitations and cannot completely clean the dirt on the inner wall of the squat toilet, so it will cause dirt to accumulate, so that the squat toilet will be difficult to remove by manpower after long-term use. Usually, cleaning workers will use chemical reagents to achieve the purpose of cleaning, but long-term use of chemical reagents will corrode the surface of the squat toilet, reducing the life of the toilet.

The pressurized water flows through the solenoid valve and is controlled by the solenoid valve outlet pipe to the automatic rotating nozzle of the rotating nozzle device of the cleaning trolley through a hose. The automatic rotating nozzle automatically rotates 360 degrees under the action of the high-pressure water jet to comprehensively clean the squat toilet.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0031] Example 1

[0032] like Figure 1 A fully automatic toilet cleaning device includes a box body 1 and a cleaning trolley 2. The box body 1 is fixed to the ground by legs 3. A switch console is provided on the box body 1. The switch console is provided with a cleaning button, a flushing button, a stop button, etc. The cleaning trolley 2 is located below the box body 1 and connected to the box body 1 through a water outlet pipe.

[0033] like Figure 2 and Figure 3 The side of the box 1 is provided with a water inlet 101, and the box 10 is provided with a water storage tank 102, a pressure pump 103 and a solenoid valve 104. A float valve 109 is provided at the water inlet 101 in the water storage tank 102. The pressure pump 103 is connected to the water storage tank 102 through a pressure pump water inlet pipe 105, and the solenoid valve 104 is connected to the pressure pump 103 through a solenoid valve water inlet pipe 106. The cleaning trolley 2 is connected to the solenoid valve 104 through a solenoid valve outlet pipe 107. The box 10 is also provided with a gas-sensitive infrared sensor 108 and a controller. The pressure pump 103, the solenoid valve 104 and the gas-sensitive infrared sensor 108 are all electrically connected to the controller. In this embodiment, the gas-sensitive infrared sensing device 108 includes a box body 1081 and a gas-sensitive module and an infrared sensing module disposed in the box body 1081. The box body 1081 is disposed on the box body 1, and the gas-sensitive module and the infrared sensing module are both electrically connected to the controller. More specifically, the gas-sensitive module is a gas-sensitive sensor for detecting gases such as ammonia or hydrogen sulfide, and the infrared sensing module is an infrared sensor for detecting whether there is someone in the squatting position.

[0034] The water storage principle of the water storage tank 102 is as follows: water flows into the water storage tank 102 through the water inlet 101. As the water in the water storage tank 102 accumulates, the float valve 109 will be lifted by the water, and the piston at the end of the float valve 109 will slowly block the water inlet. When the float valve 109 is at a certain height, the water inlet 101 will be completely blocked, thereby achieving the purpose of water storage. When the accumulated water in the water storage tank 102 flows out through the water inlet thick pipe 44 or the booster pump water inlet pipe 105, the balance in the water storage tank 102 is broken, the float valve 109 sags under the action of water flow and gravity, and the end piston no longer blocks the water inlet 101, and the water storage tank 102 stores water again. The whole process is in a cycle state.

[0035] like Figure 4The cleaning vehicle 2 includes a vehicle body 21, in which a crawler transmission device 22, a screw transmission device 23 and a rotating nozzle device 24 are arranged. There are two crawler transmission devices 22, which are respectively arranged on both sides of the screw transmission device 23, and the rotating nozzle device 24 is arranged on the middle part of the screw transmission device 23. The crawler transmission device 22 includes a double-axis motor 221, which is fixed on a fixed frame in the vehicle body 21, and first driving wheels 222 are installed at both ends of the double-axis motor 221. Two first driven wheels 223 are also arranged on the fixed frame, and the two first driven wheels 223 are connected to the two first driving wheels 222 through crawlers 224 respectively.

[0036] Furthermore, the screw transmission device 23 includes a frame 231, a motor 232 arranged on the side of the frame 231, a second driving wheel 233 arranged on the output shaft of the motor 232, a second passive wheel arranged on the frame 231 and connected to the second driving wheel 233 through a synchronous belt 234, and a first guide rod 235, a second guide rod 236, a first guide slider 237 and a second guide slider 238 arranged in the frame 231, two fixing frames provided with the dual-axis motor 221 are respectively fixed on the two outer sides of the frame 231, the first guide rod 235 and the second guide rod 236 are spaced apart in the frame 231, and both ends of the first guide rod 235 and the second guide rod 236 are fixedly connected to the frame 231. The first guide slider 237 and the second guide slider 238 are respectively inserted into the first guide rod 235 and the second guide rod 236 through the connecting ear 5. The first guide slider 237 and the second guide slider 238 are connected by two connecting rods 6. The fixing part 241 in the rotating nozzle device 24 is fixed on the connecting rod 6, and the upper part of the first guide slider 237 is also fixedly inserted into the synchronous belt 234 through a hollow block 7, so as to drive the first guide slider 237 to slide left and right along the first guide rod 235 and drive the second guide slider 238 to slide left and right along the second guide rod 236 through the synchronous belt 234, thereby driving the rotating nozzle device 24 to move left and right.

[0037] like Figure 5The rotating nozzle device 24 includes a fixing part 241, and two connecting ears at the bottom of the fixing part 241 are respectively fixedly arranged on two connecting rods 6. The solenoid valve water outlet pipe 107 is connected to the fixing part 241 through a hose 8, and a threaded interface 247 connected to the hose 8 is provided on the fixing part 241. The fixing member 241 is provided with a lock 242, and the lock 242 is provided with a nut 243, so that one end of the solenoid valve outlet pipe 107 can be fixed to the fixing member 241 through the lock 242 and the nut 243. The fixing member 241 is also provided with a spherical groove 244 connected to the threaded interface, and the spherical groove 244 includes a spherical groove interface upper end 2441 and a spherical groove lower end 2442. The spherical groove interface upper end 2441 is connected to the spherical groove lower end 2442 by bolts, and the threaded interface 247 is connected to the fixing member 241 by bolts with the spherical groove interface upper end 2441. A hollow ball-joint connecting rod 245 is connected in the space of the spherical groove 244 , and the upper end of the ball-joint connecting rod 245 and the threaded interface 247 are sealed by a first sealing ring 249 , and the lower end extends out of the fixing member 241 and is connected to an automatic rotating nozzle 246 via a hollow joint 248 .

[0038] Among them, the hollow joint 248 is provided with a hollow joint inner connector 2481 and a rotating nozzle connector 2482, the lower end of the ball joint connecting rod 245 is connected to the hollow joint inner connector 2481 by bolts, and the automatic rotating nozzle 246 is connected to the rotating nozzle connector 2482 by bolts to fix the automatic rotating nozzle 246 on the rotating nozzle connector 2482, the hollow joint inner connector 2481 is provided with a ball groove, and the outer surface of the rotating nozzle connector 2482 is also provided with a ball groove, the hollow joint inner connector 2481 and the rotating nozzle connector 2482 are connected by a ball 2484, and a second sealing ring 2483 is also provided between the rotating nozzle connector 2482 and the automatic rotating nozzle 246, and the automatic rotating nozzle 246 can drive the rotating nozzle connector 2482 to rotate in the hollow joint 248 through the ball 2484.

[0039] Movement principle of cleaning trolley 2: When the gas-sensitive infrared sensor 108 detects excessive ammonia and no one is squatting, the information is transmitted to the controller, and the controller controls the double-axis motor 221 inside the cleaning trolley 2 to start working. The double-axis motor 221 drives the entire crawler transmission device 22 to move through the rotation of the first driving wheel 222. The crawler transmission device 22 is clamped on the body 21 of the cleaning trolley by a clamp ring. When the crawler transmission device 22 moves, the entire cleaning trolley can move, so the cleaning trolley 2 will walk out from the bottom of the box 1. The moving distance of the cleaning trolley 2 can be preset in the controller.

[0040] When the cleaning trolley 2 runs to the squat toilet position, the motor 232 controls the second driving wheel 233 to rotate, and drives the first guide slider 237 to slide left and right along the first guide rod 235 through the synchronous belt 234, and drives the second guide slider 238 to slide left and right along the second guide rod 236, thereby driving the rotating nozzle device 24 to move left and right to achieve the purpose of comprehensively cleaning the squat toilet.

[0041] Furthermore, if Figure 6 The automatic rotating sprinkler 246 includes a cylinder 2461 and a water outlet main pipe 2462 and a water outlet branch pipe 2463 fixed in the cylinder 2461. The cylinder 2461 is connected to the rotating sprinkler connector 2482. The water outlet main pipe 2462 and the water outlet branch pipe 2463 are both connected to the inside of the ball joint connecting rod 245 and the hollow joint 248. The water outlet main pipe 2462 is vertically arranged, and there are multiple water outlet branch pipes 2463. The multiple water outlet branch pipes 2463 are fixedly arranged on the outer circumference of the water outlet main pipe 2462 and fixedly connected to the inner surface of the cylinder 2461. The multiple water outlet branch pipes 2463 are curved pipes. The water outlet angle of the curved pipe is 30-35 degrees with the vertical direction, preferably 32 degrees, and the curvature of the multiple curved pipes is consistent.

[0042] The rotating working principle of the rotating nozzle device 24: the fixed threaded interface in the rotating nozzle device 24 is connected to the hose and fixed by the lock 242 and the double nut 243. The high-pressure jet is injected into the automatic rotating nozzle 246. Under the movement of the cleaning trolley 2 and the first guide slider 237 and the second guide slider 238, the automatic rotating nozzle 246 can move to cover the entire squat toilet. Under the impact of the high-pressure water flow, the automatic rotating nozzle 246 automatically rotates, and the ball-jointed connecting rod 245 swings in the spherical groove 244 under the recoil force of the water flow (because the spherical groove 244 contains a first sealing ring 249, the recoil water flow will not leak out). The swing angle is about 10 degrees with the vertical normal, which can greatly increase the cleaning range of the cleaning trolley 2.

[0043] Automatic rotating nozzle 246 rotation and design: The water outlet of the automatic rotating nozzle 246 is composed of a main water outlet of a vertical water outlet main pipe 2642 and a plurality of water outlets of a curved water outlet branch pipe 2463. The angle between the water outlet angle of the water outlet branch pipe 2463 and the vertical direction is 32 degrees, and the curvature of the water outlet branch pipe 2463 is consistent within the same circumference. Therefore, under the impact of high-pressure water flow, the inner wall of the pipe of the water outlet branch pipe 2463 will be uniformly subjected to the horizontal impact force in the clockwise direction around the circumference, so that the purpose of automatic rotation of one end of the automatic rotating nozzle 246 in the rotatable joint 248 can be achieved. When the automatic rotating nozzle 246 moves to the left limit, the water flow ejected by the curved water outlet branch pipe 2463 just sprays to the leftmost end of the squat toilet, and the same is true at the right limit. Considering the relevant factors such as the water outlet angle and the different depths of the squat toilet, it is best to set the height of the automatic rotating nozzle 246 from the bottom surface to 70mm.

[0044] Furthermore, if Figure 2 and Figure 3 The fully automatic toilet cleaning device also includes a manual pressurizing device 4, which includes a telescopic handle 41, a piston cylinder 42 and a foot pressure plate 43. The telescopic handle 41 is arranged on the top of the box body 1, and the piston cylinder 42 is arranged in the box body 1. One end of the telescopic handle 41 is connected to one end of the piston rod 421 in the piston cylinder 42. One side of the piston cylinder 42 is connected to the water storage tank 102 through a water inlet thick pipe 44. The lower part of the piston cylinder 42 is located below the piston rod 421 and is also provided with an energy storage spring 422. When high-pressure water is pressed into the piston cylinder 42, the energy storage spring 422 is compressed to maintain the water pressure. The foot pressure plate 43 is arranged on the side of the box body 1 and is connected to the piston cylinder 42 through a pressurized water pipe 45 and a water outlet thick pipe 46, wherein the pressurized water pipe 45 and the water outlet thick pipe 46 are connected and conducted, and a one-way valve is provided on the water inlet thick pipe 44 and the pressurized water pipe 45. A rod-type water valve 47 is installed on the water outlet thick pipe 45, one end of the valve stem in the rod-type water valve 47 is connected to one end of the foot pressure plate 43, and the other end of the foot pressure plate 43 passes through the side of the box body 1 and extends out of the box body 1. A spring 48 is also connected to the upper surface of the end of the valve stem in the rod-type water valve 47 connected to the foot pressure plate 43, and the other end of the spring 48 is fixed to the water outlet thick pipe 46 and is located above the rod-type water valve 47.

[0045] Manual pressurization principle: the telescopic handle 41 is connected to the piston rod of the manual pressurization device 4, and the piston in the piston cylinder 42 can be driven to move downward by pressing the telescopic handle 41. The pressure change caused by the piston causes the water in the water storage tank 102 to be sucked into the piston cylinder 42 through the water inlet thick pipe 44. The telescopic handle 41 is pressed down continuously, and the water flow in the piston cylinder 42 is pressed into the pressurized water pipe 45 and then into the water outlet thick pipe 46. The water outlet thick pipe 46 is controlled by the foot pressure plate 43, and the internal water flow cannot be discharged. Therefore, after pressing down the telescopic handle 41 and sucking a certain amount of water, continuing to press down the telescopic handle 41 will pressurize the internal water to a certain extent. When it is difficult to press down the telescopic handle 41, the water inside the piston cylinder 42 has been pressurized to a certain extent. Pressing the foot pressure plate 43, the rod-type water valve 47 opens, and a water flow with a certain pressure can be released, which is conducive to the removal of dirt in the toilet. After the foot pressure plate 43 is released, the rod-type water valve 47 is closed under the action of the spring 48, and the water flow stops flowing out. (Manually pressurizing the water flow will not cause the water flow pressure to be too high, causing the excrement to splash.)

[0046] Furthermore, a water gun 9 is provided on the side of the box body 1 through a buckle, and the water gun 9 is connected to the electromagnetic valve through a water gun connecting pipe 91. For dirt that is very difficult to clean, the water gun 9 can be used for cleaning, and the water flow can be controlled by the electromagnetic valve 2 to be sent to the water gun 9 through the water gun connecting pipe 91, and the high-pressure water flow is ejected by pressing the water gun handle.

[0047] Furthermore, an ultraviolet sterilization device 25 is also provided on the body 21 of the cleaning vehicle 2 .

[0048] When the present invention is used, first, when the gas-sensitive infrared sensor 108 detects excessive ammonia and there is no one in the squatting position, the controller controls the cleaning trolley 2 to run to the squatting position through the crawler transmission device 22. Then, the booster pump 103 starts to work, and the ordinary water flow in the water storage tank 102 is drawn out through the booster pump water inlet pipe 105 and pressurized into a high-pressure water flow, and the high-pressure water flow is sent to the solenoid valve 104 through the solenoid valve water inlet pipe 106. The pressurized water flows through the solenoid valve 104 and is controlled by the solenoid valve outlet pipe 107 through a hose to the automatic rotating nozzle 246 of the rotating nozzle device 24 of the cleaning trolley 2. The hose 8 is locked and fixed to the rotating nozzle device 24 by the lock 242 and the double nut 243. The automatic rotating nozzle 246 automatically rotates 360 degrees under the action of the high-pressure water jet to fully clean the squat toilet. If there is a person going to the toilet at this time, just press the stop button in the switch console on the box body 1 to immediately stop the cleaning trolley 2 from working and immediately reset the cleaning trolley 2 to the bottom of the box body 1 by controlling the crawler conveyor 22.

[0049] When a power outage occurs, the cleaning trolley 2 will not be able to perform high-pressure cleaning work. At this time, the manual pressurizing device 4 can be used to increase the water flow intensity to better flush away the excrement. At this time, the manual pressurizing device 4 does not play a high-pressure cleaning role, but only plays a role in flushing away the excrement.
