DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention. Example

[0024] A pest control spray device, such as Figure 1-Figure 4 As shown, it includes a medicine box 1, a cover 11, a hard water pipe 12, a soft water pipe 1201, a nozzle 13, a connecting frame 14, a water pump 15 and a pressurizing mechanism. The cover 11 is slidably connected to the top of the medicine box 1, the water pump 15 is fixedly connected to the lower left side of the medicine box 1, the left side of the water pump 15 is connected and fixedly connected to the soft water pipe 1201, the other end of the soft water pipe 1201 is connected and fixedly connected to the hard water pipe 12, the other end of the hard water pipe 12 is connected and rotatably connected to the nozzle 13, the connecting frame 14 is fixedly connected to the outer side of the middle part of the hard water pipe 12, the left and right parts of the front side of the medicine box 1 are fixedly connected to shoulder straps, and the connecting frame 14 is provided with a pressurizing mechanism.

[0025] like Figure 3 and Figure 4As shown, the pressurizing mechanism includes an air pump 2, a push rod 21, a push block 22, a spring 23, an air pipe 24, a connecting pipe 25, a baffle 26 and a top spring 27. The air pump 2 is fixedly connected to the rear side of the connecting frame 14, and a spring 23 is fixedly connected between the piston rod of the air pump 2 and the connecting frame 14. The connecting frame 14 is rotatably connected with the push rod 21, and the bottom end of the push rod 21 is fixedly connected to the push block 22. One side of the push block 22 is arc-shaped, and the push block 22 is in contact with the piston rod of the air pump 2. One end of the air pipe 24 is connected to the air pump 2, and the other end of the air pipe 24 is connected to the soft water pipe 1201. The end of the air pipe 24 close to the water pump 15 is connected and fixedly connected to the connecting pipe 25. The connecting pipe 25 is slidably connected with a baffle 26, and a top spring 27 is fixedly connected between the baffle 26 and the connecting pipe 25.

[0026] like Figure 5 As shown, it also includes a circular ring 3, a stirring plate 31, a pull rope 32, a tension spring 33 and a placement rack 34. The placement rack 34 is fixedly connected to the left and right sides of the bottom of the medicine box 1, and the lower part of the placement rack 34 is slidably connected to the circular ring 3. The stirring plates 31 are slidably connected to the left and right sides of the inner wall of the medicine box 1. The tension spring 33 is fixedly connected between the stirring plate 31 and the medicine box 1. The pull rope 32 is slidably connected to the left and right sides of the inside of the medicine box 1, wherein the pull rope 32 is Y-shaped, one end of the pull rope 32 is fixedly connected to the circular ring 3 on the same side, and the other two ends of the pull rope 32 are fixedly connected to the stirring plates 31 on the same side.

[0027] like Figure 6 and Figure 7 As shown, it also includes a casing 4 and a rotating ball 41. The casing 4 is fixedly connected to the outer side of the nozzle 13, and a plurality of rotating balls 41 are movably connected between the nozzle 13 and the casing 4.

[0028] like Figure 7 As shown, the opening of the nozzle 13 is an oblique opening, which is used to drive the nozzle 13 to rotate while spraying the liquid medicine.

[0029] like Figure 5 As shown, the ring 3 is made of elastic rubber material and is used for being sleeved and fixed on the human leg.

[0030] When people need to spray insecticides or pesticides on plants in a large area outdoors, they can first open the lid 11, add an appropriate amount of water and medicine into the medicine box 1, and then cover the lid 11 to prevent the liquid medicine from leaking. Then, the paired rings 3 are taken off the placement rack 34 and fixed at the ankles of the legs respectively. Then, the medicine box 1 is carried on the back with the strap and the nozzle 13 is aimed at the plants. Then, the water pump 15 is turned on, and the liquid medicine is ejected from the medicine box 1 through the soft water pipe 1201 and the hard water pipe 12 in turn, and finally from the nozzle 13. Since the water outlet of the nozzle 13 is an oblique mouth, the nozzle 13 13 will continue to rotate with the shell 4, and the small balls placed between the nozzle 13 and the shell 4 will start to roll randomly and collide with each other. At this time, the nozzle 13 will vibrate to make the medicine pass through the nozzle 13 faster, which can also prevent the nozzle 13 from being blocked to a certain extent, and make the spray particles smaller and the spraying more uniform. After that, people will move while spraying the medicine, so as to spray the medicine everywhere in the farm. During this period, when people alternately lift their legs forward, they will pull the pull rope 32, driving the stirring plates 31 on both sides of the medicine box 1 to move up and down, and the tension spring 33 will also shrink back and forth to reset, so as to spray the medicine. Stirring can make the medicine dissolve better in the water, enhance the effect of the medicine solution, and prevent the medicine from settling and clogging the nozzle 13. When the nozzle 13 is blocked by medicine particles or impurities in the water, people can rotate the push rod 21 to drive the push block 22 to move towards the direction close to the hard water pipe 12. The movement of the push block 22 will squeeze the piston rod and make the gas in the pump 2 enter the connecting pipe 25 through the air pipe 24. The spring 23 is then compressed, and then the gas squeezes the baffle 26, so that the baffle 26 moves towards the direction close to the hard water pipe 12 until it no longer blocks the connecting pipe 25. , the top spring 27 is immediately compressed, and the gas enters the hard water pipe 12 through the connecting pipe 25, thereby increasing the water pressure in disguise and ejecting the blocked impurities. After releasing the push rod 21, the push block 22, the piston rod and the push rod 21 move in the opposite direction and reset under the action of the spring 23. The baffle 26 also moves in the opposite direction and resets under the action of the top spring 27 to prevent the liquid medicine from flowing back into the air pipe 24. During the spraying of the liquid medicine, people can also increase the water pressure by rotating the push rod 21 at intervals, so that the nozzle 13 can spray the liquid medicine farther, increase the spraying distance, and speed up the spraying efficiency.

In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to this application.
