Since the connecting loop is elastic, the second pulling rope will drive the connecting loop and then tighten the outer edge of the isolation bag, reducing the covered range of the isolation bag, thus reducing the movable range of the bee colony and making it more convenient for the high-pressure water flow to wash the honeycomb and the bee colony.

[0018] 3. The present invention covers the spray head by setting a rotating frame. Thus, when storing and using the device, the rotating frame can protect the spray head, preventing the spray head from being damaged due to external reasons such as knocking.

[0019] 4. The present invention is provided with a collection bag which can hold the honeycomb and the bee colony to prevent them from falling out. Then, by pulling the third pulling rope, the third pulling rope pulls the first connecting rope and then pulls the second connecting rope, and the first connecting rope pulls the third connecting rope, causing the opening of the collection bag to tighten. By setting the first magic tape and the second magic tape, people can separate the collection bag from the isolation bag and clean the collection bag together with the honeycomb and the bee colony, thus shortening the time for people to clean the honeycomb fragments and the bee colony corpses and avoiding the situation that a small number of wasps resume their activities and harm people due to too long time.

The left side of the cleaning pump mechanism 1 is connected to a first fixing member 17. Several protrusions are provided on the inner side of the left part of the first fixing member 17. A connecting pipe 15 is clamped to the left part of the first fixing member 17. A guiding ring 13 is fixed to the left part of the cleaning pump mechanism 1, and a guiding ring 13 is also fixed to the middle of the connecting pipe 15. The left part of the connecting pipe 15 is fixedly connected to a second fixing member 110. Several protrusions are also provided on the inner side of the left part of the connecting pipe 15. Five support frames 19 are rotatably connected to the second fixing member 110 in the circumferential direction. A first spring 112 is fixed to the side of each support frame 19 away from the second fixing member 110. A third fixing member 113 is fixed to each first spring 112. A connecting ring 181 is fixed between the third fixing members 113. The connecting ring 181 is elastic. An isolation bag 18 is fixedly connected between the connecting ring 181 and the second fixing member 110. The side of the isolation bag 18 close to the second fixing member 110 is provided with a plurality of openings. The isolation bag 18 is elastic. A rotating assembly capable of rotating the support frames 19 is connected to the connecting pipe 15. A fixing assembly capable of fixing the isolation bag 18 is connected to the support frames 19. A water spraying assembly capable of spraying water is connected to the connecting pipe 15. A pulling assembly capable of pulling 116 is connected to the cleaning pump mechanism 1.

[0040] Please refer to Figures 3-6 , the rotating assembly includes a first sliding member 116. The first sliding member 116 is slidably connected to the connecting pipe 15. A third spring 118 is fixed between the second fixing member 110 and the first sliding member 116. A fourth fixing member 117 is fixed to the connecting pipe 15. Five connecting members 115 are rotatably connected to the first sliding member 116 in the circumferential direction. Each connecting member 115 is rotatably connected to the corresponding support frame 19.

[0041] Please refer to Figure 2 and Figure 7 , the water spraying assembly includes a connecting column 120. The connecting column 120 is clamped and communicated with the left part of the connecting pipe 15. A nozzle 111 is rotatably connected to the connecting column 120. The connecting column 120 is communicated with the nozzle 111. A plurality of obliquely arranged water spraying ports are provided on the side of the nozzle 111. A water spraying port is also provided on the left end face of the nozzle 111.

[0042] Please refer to Figure 2 , Figure 4 and Figure 6, the pulling component includes a cable pulley 14 which is rotatably connected to the upper side of the left part of the cleaning pump mechanism 1. A handle is provided on the rear upper side of the cable pulley 14. A first pulling rope 16 is wound around the cable pulley 14. A self-locking device is provided on the cable pulley 14. One end of the first pulling rope 16 is fixed to the cable pulley 14, and the other end of the first pulling rope 16 passes through two guiding rings 13, then passes through the fourth fixing member 117, and finally bypasses the second fixing member 110 and is fixed to the first sliding member 116.

[0043] Please refer to Figures 3-5 , the fixing component includes five second springs 114 which are respectively fixedly connected to the middle parts of different support frames 19. Fifth fixing members 119 are fixedly connected to the second springs 114. The isolation bag 18 and the fifth fixing members 119 are fixedly connected.

[0044] Please refer to Figure 1 , it further includes a button 101 which is arranged on the cleaning pump mechanism 1. The button 101 and the cleaning pump mechanism 1 are electrically connected through a control module.

[0045] When people need to clean the wasp nest on the eaves, this device can be used for operation. First, people estimate the distance from the nozzle 111 to the wasp nest. Since both the connecting column 120 and the first fixing member 17 are in snap-fit with the connecting pipe 15, if the distance from the nozzle 111 to the wasp nest is not enough, people can connect multiple connecting pipes 15 between the connecting column 120 and the first fixing member 17 to make the length of the device longer, so that the nozzle 111 can reach near the nest. Then people hold the cleaning pump mechanism 1 by hand and connect the water inlet 12 to an external water source, and then adjust the power of the cleaning pump mechanism 1 by turning the adjustment knob 11, so that the pumping power of the cleaning pump mechanism 1 changes, and then the water pressure of the water discharged from the nozzle 111 can be changed. When people adjust to the desired water pressure, people hold the cleaning pump mechanism 1 by the handle on the rope pulley 14 and rotate it counterclockwise. The rope pulley 14 drives the first pulling rope 16 to wind up, making the first pulling rope 16 taut. Then the first pulling rope 16 drives the first sliding member 116 to move towards the second fixing member 110. The third spring 118 is compressed. The first sliding member 116 drives the connecting members 115 to move towards the second fixing member 110. The connecting members 115 squeeze the support frames 19, making the support frames 19 rotate towards the sides away from each other. The support frames 19 drive the first spring 112 and then drive the third fixing members 113 to rotate towards the sides away from each other, making the third spring 118 move towards the second fixing member 110. The support frames 19 drive the second spring 114 and then drive the fifth fixing members 119 to rotate towards the sides away from each other. The fifth fixing members 119 can fix the isolation bag 18, making the isolation bag 18 fixed on the support frames 19, thus preventing the middle part of the isolation bag 18 from loosening. The third spring 118 and the fifth fixing members 119 both drive the isolation bag 18 to flip towards the nest, so that the isolation bag 18 covers the nest. Then people can release the handle of the rope pulley 14. Since a self-locking device is provided on the rope pulley 14, it can lock the first pulling rope 16 to prevent the first pulling rope 16 from loosening. Then people press the button 101, and the button 101 controls the cleaning pump mechanism 1 to start. The cleaning pump mechanism 1 pumps water according to the previously adjusted power. The pumped water enters the connecting pipe 15 through the cleaning pump mechanism 1 and then sprays out from the nozzle 111 through the connecting column 120. The sprayed high-pressure water flow cleans and destroys the nest. Since the isolation bag 18 covers the nest in advance, the wasp colony will not run out to harm people, thus achieving the purpose of protecting people. Through the long-term flushing of the high-pressure water flow, all the wasp colonies die. The sprayed water can flow out through the opening of the isolation bag 18 near the second fixing member 110. When all the wasp colonies are dead, people manually rotate the rope pulley 14 clockwise. The rope pulley 14 no longer winds up the first pulling rope 16, making the first pulling rope 16 no longer taut. The first pulling rope 16 loosens and no longer pulls the first sliding member 116.The third spring 118 resets and drives the first sliding member 116 to move away from the second fixing member 110. The first sliding member 116 drives the connecting member 115 to move away from the second fixing member 110 for resetting. The connecting member 115 drives the support frames 19 to rotate towards the side close to each other. The support frames 19 drive the first spring 112 and then drive the third fixing member 113 to rotate towards the side close to each other, causing the third spring 118 to move away from the second fixing member 110. The support frames 19 drive the second spring 114 and then drive the fifth fixing member 119 to rotate towards the side close to each other. Both the third spring 118 and the fifth fixing member 119 drive the isolation bag 18 to flip and reset away from the honeycomb. Then people move this device away from the honeycomb, and people clean the corpses of the bee colony and the honeycomb fragments that have fallen, thus completing the cleaning of the honeycomb under the eaves. For the above operations, people wind up the first pulling rope 16 by rotating the rope pulley 14. The first pulling rope 16 pulls the first sliding member 116 towards the second fixing member 110. The first sliding member 116 drives the connecting member 115 to move towards the second fixing member 110. The connecting member 115 drives the support frames 19 to flip, so that the isolation bag 18 flips. The isolation bag 18 can cover the honeycomb, so that when people clean the honeycomb, the bee colony will not run out to hurt people, thus achieving the purpose of protecting people.

[0046] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 8-11 There is also a tightening mechanism for reducing the gap between the isolation bag 18 and the wasp honeycomb, reducing the activity range of wasps, and facilitating people to spray water to clean the honeycomb. The tightening mechanism includes a second sliding member 21. The second sliding member 21 is slidably connected to the connecting pipe 15. Five guide rods 22 are circumferentially fixed between the fourth fixing member 117 and the second fixing member 110. The second sliding member 21 and the guide rods 22 are slidably connected. Five fourth springs 23 are fixedly connected between the second sliding member 21 and the second fixing member 110. The fourth springs 23 are wound around the corresponding guide rods 22 respectively.

[0047] Please refer to Figures 8-11 There are also five second pulling ropes 2. One ends of the second pulling ropes 2 are circumferentially fixed on the fourth fixing member 117. The other ends of the second pulling ropes 2 bypass the second sliding member 21 and are circumferentially fixed on the connecting ring 181.

[0048] Since the area that can be covered by the part where the isolation bag 18 is fixed to the connecting ring 181 is relatively large, larger than the area scoured by the high-pressure water flow, a tightening mechanism is provided to tighten the isolation bag 18, thereby reducing the activity range of the wasp colony and facilitating the scouring of the honeycomb by people. The following is its working principle: When people want to clean the honeycomb, they wind the first pulling rope 16 by rotating the rope wheel 14 counterclockwise. The first pulling rope 16 pulls the first sliding member 116 towards the second fixing member 110. The first sliding member 116 drives the connecting member 115 to move towards the second fixing member 110. The third spring 118 is compressed. The connecting member 115 drives the support frame 19 to turn over, so that the isolation bag 18 turns over and covers the honeycomb. During the process of the first sliding member 116 moving towards the second fixing member 110, the first sliding member 116 will contact and squeeze the second sliding member 21. The first sliding member 116 drives the second sliding member 21 to move towards the second fixing member 110. The fourth springs 23 are all compressed. The second sliding member 21 moves towards the second fixing member 110, causing the second pulling ropes 2 to be pulled by the second sliding member 21. The other ends of the second pulling ropes 2 are fixed to the connecting ring 181. Due to the supporting effect of the support frame 19 on the isolation bag 18, when the second pulling ropes 2 pull the connecting ring 181, the connecting ring 181 will not drive the isolation bag 18 to retract. Thus, the ends of the second pulling ropes 2 connected to the connecting ring 181 move towards each other. Since the connecting ring 181 is elastic, the second pulling ropes 2 will drive the connecting ring 181 and then drive the outer edge of the isolation bag 18 to tighten. The covered area of the isolation bag 18 becomes smaller, so that the movement range of the wasp colony becomes smaller, making it more convenient for the high-pressure water flow to scour the honeycomb and the wasp colony. After the wasp honeycomb is cleaned, people rotate the rope wheel 14 clockwise. The rope wheel 14 releases the first pulling rope 16. The first pulling rope 16 no longer pulls the first sliding member 116. The third spring 118 resets and drives the first sliding member 116 to move away from the second fixing member 110. The first sliding member 116 drives the connecting member 115 to move away from the second fixing member 110. The connecting member 115 drives the support frame 19 to turn over and reset in the opposite direction, so that the isolation bag 18 turns over and resets. The first sliding member 116 disengages from the second sliding member 21. The fourth springs 23 are all reset and drive the second sliding member 21 to move away from the second fixing member 110. The second pulling ropes 2 all move and reset. The above operation drives the second sliding member 21 to move towards the second fixing member 110 through the first sliding member 116. The second sliding member 21 pulls the second pulling ropes 2, so that the second pulling ropes 2 pull the connecting ring 181, so that the ends of the second pulling ropes 2 connected to the connecting ring 181 move towards each other. Since the connecting ring 181 is elastic, the second pulling ropes 2 will drive the connecting ring 181 and then drive the outer edge of the isolation bag 18 to tighten. The covered area of the isolation bag 18 becomes smaller, so that the movement range of the wasp colony becomes smaller.Make it more convenient for high-pressure water flow to wash the honeycombs and bee colonies.

[0049] Please refer to Figures 12-14 It also includes a protection mechanism that can protect the nozzle 111 and prevent the nozzle 111 from being knocked during storage and use. The protection mechanism includes four telescopic rods 31. The telescopic rods 31 are all circumferentially fixed on the second fixing member 110. The other ends of the telescopic rods 31 are jointly rotatably connected to a rotating frame 3. A water outlet is provided on the side of the rotating frame 3 away from the telescopic rods 31. The side surface of the rotating frame 3 is set in a hollowed-out shape. A fifth spring 32 is fixedly connected between each telescopic rod 31 and its telescopic end.

[0050] The connecting column 120 is in snap-fit connection with the connecting pipe 15, so that the nozzle 111 can be replaced after being damaged. However, in order to save resources, a protection mechanism is provided to protect the nozzle 111 and prevent the nozzle 111 from being knocked during storage and use. The following is its working principle: Usually when storing, the rotating frame 3 covers the nozzle 111 to protect the nozzle 111. When people use this device, the spray nozzles on the side of the nozzle 111 are all inclined, and the rotating frame 3 and the telescopic rods 31 are all rotatably connected. Therefore, the high-pressure water flow sprayed by the nozzle 111 will drive the rotating frame 3 to rotate, and the side surface of the rotating frame 3 is hollowed out. The left side of the rotating frame 3 is open, so it will not block the high-pressure water flow from spraying. Thus, during the operation of the device, the nozzle 111 can be protected without hindering the work of the nozzle 111. When people need to replace the nozzle 111, people manually drive the rotating frame 3 to move towards the telescopic rods 31. The telescopic ends of the telescopic rods 31 all retract, and the fifth springs 32 are all compressed. The movement of the rotating frame 3 towards the telescopic rods 31 exposes the nozzle 111. Then people can disassemble the connecting column 120 to replace the nozzle 111. After replacement, people release the rotating frame 3, and the fifth springs 32 all reset to drive the telescopic ends of the telescopic rods 31 to extend and reset. The telescopic rods 31 drive the rotating frame 3 to move away from the telescopic rods 31 and reset. The above operations cover the nozzle 111 with the rotating frame 3, so that the rotating frame 3 can protect the nozzle 111 when storing and using this device, thus preventing the nozzle 111 from being damaged due to external reasons such as being knocked.

[0051] Please refer to Figures 15-17, it further includes a collection mechanism that can quickly collect the residue of the wasp nest and wasps, preventing the wasps from regaining their ability to move and sting people. The collection mechanism includes five first magic tapes 42, which are respectively arranged on different third fixing parts 113. Five sixth fixing parts 44 are circumferentially fixed on the second fixing part 110. Second magic tapes 43 are arranged on the sixth fixing parts 44. A second connecting rope 412 is fixedly connected between the second magic tapes 43. One ends of two first connecting ropes 411 are circumferentially fixed on the second connecting rope 412. A third pulling rope 41 is fixedly connected between the other ends of the first connecting ropes 411. A third connecting rope 413 is fixedly connected between the first connecting ropes 411. A collection bag 4 is slidably connected between the first connecting ropes 411. The collection bag 4 is elastic. The collection bag 4 is slidably connected to the third connecting rope 413 and the second connecting rope 412.

[0052] Because after flushing the wasp nest with high-pressure water flow, people directly move the device away and then clean up the fragments of the fallen wasp nest and the corpses of the wasp colony. Since the fallen fragments and corpses will be scattered all over the place, it takes people a certain amount of time to clean them up. During this cleaning process, there may be wasps that haven't died yet and regain their mobility, which may harm people. Therefore, a collection mechanism is provided that can quickly clean up the nest fragments and the corpses of the colony. The following is what happens after people finish flushing the nest. People do not rotate the rope wheel 14 clockwise first, so that the isolation bag 18 can drive the collection bag 4 to hold the nest and the colony, preventing the nest and the colony from falling scattered. Then people drive the device downward. Because the collection bag 4 has a large capacity and is elastic, the isolation bag 18 can hold the nest and the colony. At the same time, because the isolation bag 18 is tightened under the pulling action of the second pull rope 2, the opening of the collection bag 4 driven by the isolation bag 18 becomes smaller. During the process of the isolation bag 18 driving the collection bag 4 and then driving the nest and the colony down, a large amount of the nest and the colony can be prevented from falling. After the isolation bag 18 drives the collection bag 4 to drive the nest and the colony down, people pull the third pull rope 41. The third pull rope 41 pulls the first connecting rope 411 and then pulls the second connecting rope 412. The second connecting rope 412 drives the second magic tapes 43 to be torn off. At the same time, because the second connecting rope 412 is slidably connected to the collection bag 4, pulling the second connecting rope 412 can tighten the side of the collection bag 4 close to the second connecting rope 412, thus preventing the nest and the colony from falling out. The first connecting rope 411 pulls the third connecting rope 413, which can tighten the side of the collection bag 4 close to the third connecting rope 413. The collection bag 4 drives the first magic tapes 42 to move, causing the first magic tapes 42 to be torn off, so that the collection bag 4 is separated from the isolation bag 18. Then manually contract the side of the collection bag 4 close to the first magic tape 42, and then clean up the collection bag 4 containing the nest and the colony. Finally, people rotate the rope wheel 14 clockwise. The rope wheel 14 no longer winds up the first pull rope 16, so that the first pull rope 16 is no longer taut. The first pull rope 16 becomes loose and no longer pulls the first sliding member 116. The third spring 118 resets and drives the first sliding member 116 to move away from the second fixing member 110. The first sliding member 116 drives the connecting members 115 to move away from the second fixing member 110 and reset. The connecting members 115 drive the support frames 19 to rotate towards each other. The support frames 19 drive the first spring 112 and then drive the third fixing members 113 to rotate towards each other, causing the third spring 118 to move away from the second fixing member 110. The support frames 19 drive the second spring 114 and then drive the fifth fixing members 119 to rotate towards each other. The third spring 118 and the fifth fixing members 119 both drive the isolation bag 18 to flip and reset away from the nest. The above operations are achieved by setting the collection bag 4. The collection bag 4 can hold the nest and the colony to prevent them from falling out. Then by pulling the third pull rope 41,The third pull rope 41 pulls the first connecting rope 411, and then pulls the second connecting rope 412. The first connecting rope 411 pulls the third connecting rope 413, so that the opening of the collection bag 4 is tightened. By setting the first Velcro 42 and the second Velcro 43, people can separate the collection bag 4 from the isolation bag 18, and clean up the collection bag 4 together with the honeycomb and the bee colony, thus shortening the time for people to clean up the honeycomb fragments and the bee colony corpses, and avoiding the situation that a few wasps resume their actions and hurt people due to too long time.
