[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3 This utility model provides a technical solution: In this technical solution, a garden plant protection machinery control device to prevent misoperation includes a sprayer 1, one end of a spray pipe 2 is inserted into the side wall of the sprayer 1, a spray rod 3 is installed at the other end of the spray pipe 2, and a closing mechanism 4 is slidably installed on the spray rod 3. The sealing mechanism 4 includes a mounting groove 41, a spring 42, a sealing rod 43, a through hole 44, a handle 45, and a pressure ring 46. The upper end of the spray rod 3 is provided with a mounting groove 41, which is connected to the inner cavity of the spray rod 3. The sealing rod 43 is slidably installed in the mounting groove 41. The side wall of the sealing rod 43 is provided with a through hole 44. One end of the spring 42 is installed on the lower wall of the sealing rod 43, and the other end of the spring 42 is installed on the inner wall of the mounting groove 41. The outer side of the spray rod 3 is sleeved with a handle 45, and the side wall of the handle 45 is screwed into a pressure ring 46, which can press the sealing rod 43. In this technical solution, the spring 42 is always in an extended state under normal conditions, pushing the sealing rod 43 upward to seal the inner cavity of the spray rod 3, preventing the flow of pesticide and thus avoiding accidental spraying. When spraying is required, the pressure ring 46 is rotated outward to apply downward pressure to the sealing rod 43, compressing the spring 42 and causing the sealing rod 43 to slide down, so that the through hole 44 is connected to the inner cavity of the spray rod 3, and the pesticide can be sprayed out smoothly, realizing the function of pressing to open and releasing to close to prevent accidental operation.

[0015] In some technical solutions, the side wall of the sleeve 45 is provided with an annular groove 5, the inner side wall of the annular groove 5 is provided with internal thread, the pressure ring 46 includes a ring body 461 and a threaded cylinder 462, the threaded cylinder 462 is screwed into the annular groove 5 by the thread, and the ring body 461 is installed at one end of the threaded cylinder 462 located outside the annular groove 5.

[0016] In this technical solution, the internal thread of the annular groove 5 engages with the external thread of the threaded cylinder 462 to achieve an adjustable connection between the pressure ring 46 and the handle 45. By rotating the ring body 461, the threaded cylinder 462 can be driven to move axially along the annular groove 5, thereby controlling the pressure ring 46 to press the sealing rod 43.

[0017] In some technical solutions, a rubber sealing sleeve 6 is fitted onto the outer wall of the sealing rod 43. The rubber sealing sleeve 6 can fit against the inner wall of the mounting groove 41, and the through hole 44 penetrates the side wall of the rubber sealing sleeve 6.

[0018] In this technical solution, the rubber sealing sleeve 6 fits tightly against the inner wall of the mounting groove 41 and the side wall of the sealing rod 43, filling the gap between them and preventing the liquid from leaking from the mating point of the mounting groove 41 and the sealing rod 43, thus avoiding waste of the liquid and the risk of operators coming into contact with the liquid.

[0019] In some technical solutions, the inner cross section of the ring body 461 near the end of the sealing rod 43 is tapered, and the upper side wall of the sealing rod 43 is provided with an inclined surface 7, which can fit against the inner wall of the ring body 461.

[0020] In this technical solution, the conical inner wall of the ring 461 can fit well with the inclined surface 7 of the sealing rod 43, which can cause it to jam when pressing the sealing rod 43. At the same time, the contact area between the conical surface and the inclined surface 7 is larger and more stable.

[0021] In some technical solutions, the outer wall at the end of the ring 461 is provided with anti-slip texture 8.

[0022] In some technical solutions, shoulder straps 9 are installed on both the left and right sides of the side wall of the sprayer 1, and a handle 10 is installed on the upper end of the sprayer 1.

[0023] In this technical solution, the shoulder strap 9 adopts a double-shoulder force-bearing design, which can carry the sprayer 1 on the back and carry out garden plant protection operations for a long time. The handle 10 is convenient for short-distance transportation, moving up and down slopes, or grabbing when temporarily placing the sprayer 1.

[0024] Working principle: When the sprayer 1 is not in use, the spring 42 is in a naturally extended state. Its elasticity pushes the sealing rod 43 to slide upward along the mounting groove 41. The side wall of the sealing rod 43 fits tightly with the inner cavity of the spray rod 3, completely blocking the flow channel of the pesticide. No matter whether pressure is applied, the pesticide cannot be sprayed out, thus preventing misoperation. When it is necessary to carry out plant protection spraying, the operator holds the handle 45 and rotates the ring 461 outward, which drives the threaded cylinder 462 to move along the inner thread of the annular groove 5 towards the sealing rod 43. The conical inner side of the ring 461 gradually fits with the inclined surface 7 of the sealing rod 43. Continuous rotation causes the sealing rod 43 to slide downward along the mounting groove 41. When the through hole 44 on the sealing rod 43 is connected to the inner cavity of the spray rod 3, the pesticide in the sprayer 1 can form a guiding path through the spray pipe 2, the inner cavity of the spray rod 3, and the through hole 44 in sequence, and finally spray out through the nozzle at the end of the spray rod 3 to carry out the spraying operation.
