[0022] Reference Figures 1 to 4 As shown, this utility model provides a hand-push type small sprayer.

[0023] The hand-push type small sprayer includes a storage tank 100, a moving frame 200, a sprayer 300, and a reel 400.

[0024] The pesticide storage box 100 is cylindrical, and the inside of the pesticide storage box 100 is provided with a storage cavity for storing pesticides. The bottom of the pesticide storage box 100 is provided with multiple support wheels 110, which are spaced apart from each other. The support wheels 110 are universal wheels to facilitate the movement of the pesticide storage box 100 in any horizontal direction.

[0025] A connecting pipe 120 is provided on the top of the medicine storage box 100. The connecting pipe 120 extends downward into the medicine storage cavity, and the bottom end of the connecting pipe 120 extends to the bottom of the medicine storage cavity, while the top end of the connecting pipe 120 extends above the medicine storage box 100.

[0026] The side wall of the medicine storage box 100 is provided with three grooves 140. The three grooves 140 are arranged in a circular array with the axis of the medicine storage box 100 as the center, and the included angle between any two adjacent grooves 140 is 120°.

[0027] Each groove 140 is provided with a first connector 130, and the first connector 130 is provided with a buckle 131. The buckle 131 is located in the groove 140. The three buckles 131 are arranged in a circular array with the axis of the medicine storage box 100 as the center, and the included angle between any two adjacent buckles 131 is 120°.

[0028] The top of the pesticide storage tank 100 is provided with an opening, and a removable top cover 150 is provided on the opening. By removing the top cover 150, pesticides can be injected into the storage chamber through the opening, so that the pesticide storage tank 100 can be quickly replenished with pesticides.

[0029] The bottom of the mobile frame 200 is provided with multiple casters 210, which are spaced apart. The casters 210 are omnidirectional wheels to facilitate the movement of the mobile frame 200 in any horizontal direction.

[0030] The rear side of the top of the movable frame 200 is provided with a rearward extending U-shaped frame. The rear side of the U-shaped frame forms a receiving groove 220 that runs from top to bottom. The shape of the receiving groove 220 matches the shape of the medicine storage box 100. Three second connectors 230 are provided on the inner side wall of the receiving groove 220. The three second connectors 230 are arranged in a circular array with the axis of the receiving groove 220 as the center. The included angle between any two adjacent second connectors 230 is 120°.

[0031] Each second connector 230 is provided with a connecting rope 231, which is an elastic rope, and one end of the connecting rope 231 is connected to the inner wall of the receiving groove 220.

[0032] Each second connector 230 is also provided with a spring buckle 232, which is connected to the other end of the connecting rope. The spring buckle 232 includes a hook, a swing rod, a spring, and a rivet. The hook is connected to the connecting rope 231 and has a ring structure cut off on one side. The swing rod is an arc rod and is hinged to the hook by the rivet. The swing rod and the hook form a circle. The spring is located inside the swing rod. The side wall of the swing rod facing outward has a groove. The hook has a hook. The elastic force of the spring drives the swing rod to rotate so that the groove engages with the hook.

[0033] The medicine storage box 100 is pushed from back to front into the receiving groove 220 of the movable frame 200, so that the three grooves 140 and the three second connectors 230 are arranged opposite each other. The outer diameter of the medicine storage box 100 is smaller than the width of the receiving groove 220, so that a clearance space 221 is formed between the outer side wall of the medicine storage box 100 and the inner side wall of the receiving groove 220.

[0034] Taking the cooperation of one of the first connectors 130 and the second connector 230 as an example, the connecting rope 231 is pulled to bring the spring buckle 232 close to the buckle ring 131. Then, the swing rod is pushed to resist the spring force to separate the slot from the hook, so that the buckle ring 131 is engaged in the hook ring. Then, the swing rod is released to allow the spring force to drive the swing rod to rotate so that the slot is engaged in the hook, thereby connecting the buckle ring 131 with the spring buckle 232.

[0035] The three buckles 131 are connected to the three spring buckles 232 in a one-to-one correspondence.

[0036] The sprayer 300 is mounted on the movable frame 200. The sprayer 300 utilizes Bernoulli's principle of airflow shear atomization, high-pressure water flow collision atomization, charge repulsion dispersion atomization, or ultrasonic high-frequency vibration atomization.

[0037] The sprayer 300 is equipped with an inlet pipe 310 and a spray pipe 320. The inlet pipe 310 is provided with an interface to connect to the top of the connecting pipe 120 of the pesticide storage tank 100. The spray pipe 320 is connected to the outside and sprays atomized pesticide to the outside.

[0038] In this embodiment, the sprayer 300 is electric or motorized. It drives the fan impeller to rotate at high speed. The high-pressure airflow generated by the fan uses Bernoulli's principle to shear and atomize the pesticide before spraying it out from the spray pipe 320.

[0039] The take-up reel 400 is located on top of the mobile frame 200. The take-up reel 400 winds up the spray pipe 320. The spray pipe 320 is relatively long so that the user can pull the spray pipe 320 to move without moving the hand-push small sprayer.

[0040] The unused pesticide storage tank 100 is pre-filled with pesticide. After the pesticide in the storage tank 100 of the hand-push small sprayer is exhausted, the hand-push small sprayer is moved next to the pesticide-filled storage tank 100. The first connecting piece 130 of the storage tank 100 of the hand-push small sprayer is detached from the second connecting piece 230 of the moving frame 200. The inlet pipe 310 of the sprayer 300 is detached from the connecting pipe 120 of the storage tank 100, so that the exhausted storage tank 100 is removed from the moving frame 200 and pushed backward into the receiving slot 220. Then, the fully filled storage tank 100 is... The pesticide storage tank 100 is pushed from back to front into the mobile frame receiving slot 220. The first connector 130 is connected by the second connector 230, and the liquid inlet pipe 310 of the sprayer 300 is connected to the connecting pipe 120 of the full pesticide storage tank 100. Then, the hand-push small sprayer can be pushed back to the field for spraying operations. The empty pesticide storage tank 100 can be refilled with pesticide, saving the time of waiting for the pesticide storage tank 100 to be refilled. Moreover, there is no need to move the full pesticide storage tank 100, making the use of the hand-push small sprayer more convenient.

[0041] In some embodiments, the medicine storage box 100 can be prism or any shape, and a second connector 230 needs to be provided to connect the first connector 130 so that the movable frame 200 can pull the medicine storage box 100 to move.

[0042] In some embodiments, the first connector 130 and the second connector 230 can be connected in various ways, such as by screw connection or pin connection, or by direct rope binding connection.

[0043] A clearance space 221 is formed between the medicine storage box 100 and the inner wall of the receiving tank 220, which helps the multiple connecting ropes 231 to pull the medicine storage box 100 from multiple directions. The medicine storage box 100 has a movement margin in the clearance space 221, which prevents the medicine storage box 100 from hitting the receiving tank 220.

[0044] The three first connectors 130 and three second connectors 230 are configured to cooperate one-to-one. With a small number of first connectors 130 and second connectors 230, the medicine storage box 100 is securely placed in the receiving slot 220, reducing the number of times the first connectors 130 and second connectors 230 are disassembled or connected.

[0045] The first connector 130 is placed in the groove 140 on the outer wall of the medicine storage box 100 to prevent the user from being injured by the protruding first connector 130.

[0046] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
