[0027] The fourth gear 306 rotates through the gear teeth 106 to drive the gear ring 101 to rotate, the gear ring 101 is meshed with the first gear 102 and the second gear 104, the gear ring 101 drives the first gear 102 to rotate, the first gear 102 drives the first baffle 103 to rotate, the gear ring 101 drives the second gear 104 to rotate, and the second gear 104 drives the second baffle 105 to rotate. Since the first baffle 103 and the second baffle 105 are staggered with each other, they will rotate outward or outward at the same time to make the middle opening larger or smaller. Under the condition of constant water pressure, the water flow size can be adjusted individually, or it can be closed to save water resources, and the water flow always keeps flowing out from the center to impact the fan blades 201.

[0028] In this embodiment, Figure 8 , Fig. 9 As shown, the locking mechanism 300 includes a second round rod 305, a second limiting hole 310 is opened on the side of the second round rod 305 away from the housing 1, and a fourth gear 306 is installed on the side of the second round rod 305 that passes through the housing 1 toward the housing 1. A second spring 304 is sleeved on the outside of the second round rod 305, and one side of the second spring 304 is installed on the inner wall of the housing 1. A third gear 303 is installed on the side of the second spring 304 away from the housing 1. The third gear 303 is slidably connected to the second round rod 305, and the third gear 303 is sleeved on the outside A ring 301, a plurality of stop blocks 302 evenly distributed along the circumference of the first ring 301 are installed on the inner wall thereof, a second slider 308 is slidably installed inside the second stop hole 310, a disk 307 is fixedly installed on the side of the second slider 308 away from the housing 1, a second ring 309 is installed on the side of the disk 307 facing the housing 1, the second ring 309 is outside the second slider 308 and the other side is fixedly connected to the third gear 303; the opening of the first ring 301 on the side facing the disk 307 is the same size as the second ring 309;

[0029] Press the disc 307 by hand, and the disc 307 pushes the third gear 303 to slide inward on the surface of the second rod 305 through the second ring 309 and squeezes the second spring 304. At this time, the third gear 303 is staggered with the limit block 302, and the second slider 308 extends into the second rod 305 through the second limit hole 310. Then rotate the disc 307 clockwise, and the second rod 305 will drive the fourth gear 306 to rotate.

[0030] When the disc 307 is released, the second spring 304 extends outward, pushing the third gear 303 to slide on the surface of the second round rod 305 toward the inside of the first ring 301. The third gear 303 engages with the limit block 302 to prevent the second round rod 305 from driving the fourth gear 306 to rotate, thereby preventing the internal opening from becoming larger or smaller after a long period of working time, affecting the spray effect and causing a waste of water resources.

[0031] In this embodiment, Figure 6 , Figure 7 As shown, the cleaning mechanism 200 includes a bottom plate 214, and a plurality of fixing frames 209 are evenly installed on the upper end surface of the bottom plate 214 along its circumference. A cylinder 204 is installed on the upper end of the plurality of fixing frames 209. A water outlet 205 is provided on the side of the cylinder 204 away from the housing 1. The other side of the cylinder 204 is fixedly installed on the housing 1 through a through hole 207 provided on the housing 1. A valve 208 is installed on the upper end surface of the cylinder 204. A first round rod 203 is rotatably installed at the center position of the upper end surface of the bottom plate 214. The upper end surface of the first round rod 203 is A fan blade 201 is installed, a spiral blade 202 is sleeved on the outside of the first round rod 203, a filter screen 206 is sleeved on the outside of the spiral blade 202, and the filter screen 206 is installed on the inner wall of the shell 1. A first spring 212 is installed on the upper end surface of the bottom plate 214, and a sealing cover 211 is installed on the upper end surface of the first spring 212. A plurality of first sliders 210 are evenly distributed and installed on the upper end surface of the sealing cover 211 along its circumference, and the plurality of first sliders 210 are slidably installed on the shell 1 through first limiting holes 213 opened on the lower end surface of the shell 1;

[0032] Through the valve 208 installed on the cylinder 204, one of the cylinders 204 can be closed separately to achieve the desired effect with the least amount of water; the water flow impacts the fan blade 201, causing it to rotate counterclockwise, and the fan blade 201 drives the first round rod 203 to rotate counterclockwise, and the first round rod 203 drives the spiral blade 202 set on the outside to rotate, and the spiral blade 202 will clean the filter screen 206 on the outside to prevent clogging, and the spiral blade 202 will pressurize the water flow while rotating, and the water flow passes through the cylinder 204 and sprays out from the water outlet 205 to form a spray, and impurities will accumulate on the sealing cover 211; when there are more and more impurities, the spiral blade 202 will rotate slower and slower, the water outlet speed of the water outlet 205 will slow down, and the internal pressure will increase, and the water flow will increase the pressure on the sealing cover 211 When the limit is reached, the sealing cover 211 will squeeze the first spring 212, and the sealing cover 211 will slide downward in the first limiting hole 213 on the housing 1 through the first slider 210, and impurities will be ejected. At the same time, the spiral blade 202 is driven by the fan blade 201 to rotate at a high speed to clean the filter 206, which can be cleared in time to prevent blockage from causing uneven spraying and wasting water resources. In addition, there is no need to conduct separate inspections or manually disassemble the filter 206 to clean it, which is more efficient. When the cleaning is completed, the water flow can spray normally from the water outlet 205 of the cylinder 204, and the pressure of the sealing cover 211 becomes smaller, and the first spring 212 extends, pushing the first slider 210 on the sealing cover 211 to slide upward in the first limiting hole 213 on the housing 1 to complete the sealing;

[0033] In this embodiment, Figure 6As shown, the first round rod 203, the fan blade 201, the spiral blade 202, and the filter screen 206 are made of stainless steel to prevent rust and extend the service life.

[0034] Working principle: After being connected to the water pipe through the thread 2, the water pump is turned on to allow water to pass through the housing 1, and then the disc 307 is pressed by hand. The disc 307 pushes the third gear 303 to slide inward on the surface of the second round rod 305 through the second ring 309 and squeezes the second spring 304. At this time, the third gear 303 is staggered with the limit block 302, and the second slider 308 extends into the second round rod 305 through the second limit hole 310. Then the disc 307 is rotated clockwise, and the second round rod 305 will drive the fourth gear 306 to rotate. Since the fourth gear 306 is meshed with the gear teeth 106, the gear teeth 106 drive the gear ring 101 to rotate. Since the gear ring 101 is meshed with the first gear 102 and the second gear 1 04 mesh with each other, the gear ring 101 drives the first gear 102 to rotate clockwise, the first gear 102 drives the first baffle 103 to rotate, the gear ring 101 drives the second gear 104 to rotate clockwise, and the second gear 104 drives the second baffle 105 to rotate. Since the first baffle 103 and the second baffle 105 are staggered with each other, they will rotate outward at the same time to make the middle opening larger, and water will flow through. After the required spray size is adjusted, the disc 307 is released, and the second spring 304 extends outward to push the third gear 303 to slide on the surface of the second round rod 305 toward the inside of the first ring 301. The third gear 303 meshes with the limit block 302 to prevent the second round rod 305 from driving the fourth gear 306 to rotate;

[0035] When the water flows down from the opening between the first baffle 103 and the second baffle 105, it will impact the fan blade 201, causing it to rotate counterclockwise. The fan blade 201 drives the first round rod 203 to rotate counterclockwise, and the first round rod 203 drives the spiral blade 202 set on the outside to rotate. The spiral blade 202 will clean the outer filter 206 to prevent clogging, and the spiral blade 202 will pressurize the water flow while rotating. The water flow passes through the cylinder 204 and sprays out from the water outlet 205 to form a spray, and impurities will accumulate on the sealing cover 211.

[0036] When one side of the fence does not need to be sprayed, the valve 208 above the cylinder 204 can be operated to prevent passers-by from being sprayed and effectively save water resources;

[0037] When there are more and more impurities, the spiral blade 202 will rotate slower and slower, the water outlet speed of the water outlet 205 will slow down, the internal pressure will increase, and the water flow will increase the pressure on the sealing cover 211. When the limit is reached, the sealing cover 211 will squeeze the first spring 212, and the sealing cover 211 will slide downward in the first limiting hole 213 on the outer shell 1 through the first slider 210, and the impurities will be sprayed out. At the same time, the spiral blade 202 rotates at a high speed driven by the fan blade 201 to clean the filter screen 206. When the cleaning is completed, the water flow can spray normally from the water outlet 205 of the cylinder 204, the pressure of the sealing cover 211 becomes smaller, and the first spring 212 extends, pushing the first slider 210 on the sealing cover 211 to slide upward in the first limiting hole 213 on the outer shell 1 to complete the sealing, and no manual cleaning is required.
