[0002] In current agricultural, horticultural, and household cleaning settings, small fungicide sprayers, as an important tool, are widely used in various disinfection operations.
[0003] Traditional sprayers often have a relatively large volume to meet the large-capacity storage of fungicides. However, large-volume sprayers are particularly cumbersome in terms of carrying and transportation, significantly increasing the labor intensity of users. Moreover, in places with limited space, such as household kitchens, small greenhouses, or urban green belts, it is often difficult to find a suitable storage space for large-volume sprayers.
[0004] During the use of fungicides, mixing uniformity is a crucial factor. Existing large-volume sprayers are too heavy to mix fungicides by shaking the sprayer body and can only be manually operated through a stirring mechanism, which is not only time-consuming and laborious, but also may cause skin contact with fungicides during operation, posing a safety hazard.
[0005] In view of this, we propose a small fungicide sprayer to solve the existing problems. Summary of the Utility Model

One end thereof has a spray port penetrating through the nozzle 1 for spraying the fungicide outward, and the other end is communicated with the mixing chamber 13. A pressurizing component 4 is further provided on the kettle body 3. The pressurizing component 4 is hermetically connected with the chamber of the housing for pressurizing the chamber. A third pipe 16 communicating with the mixing chamber 13 is provided on the nozzle 1, and a pressure relief component 6 is provided at the other end of the third pipe 16.
[0026] In an embodiment, a raised mounting seat 11 is provided at one end of the nozzle 1 close to the nozzle of the first pipe 12. A lever 7 is hinged through the mounting seat 11. One end of the lever 7 is connected to a nozzle 2. The nozzle 2 is movably inserted into the front end of the first pipe 12. The nozzle 2 has a groove for controlling the opening and closing of the first pipe 12.
[0027] In an embodiment, the lever 7 has a long handle 73 and a short handle 71. The opposite ends of the long handle 73 and the short handle 71 are integrally formed and connected to the mounting seat 11 to rotate around the mounting seat 11. The other end of the short handle 71 is disposed outside the first pipe 12 and connected to the nozzle 2 for driving the nozzle 2 to move. A second elastic member 72 is provided between the bottom wall of the other end of the long handle 73 and the nozzle 1.
[0028] In an embodiment, the pressurizing assembly 4 includes a cylinder 43 that is hermetically connected to the kettle body 3 and the front end of which is inserted into the inner chamber of the kettle body 3. An end cover 41 is installed at the front end of the cylinder 43. The end cover 41 has an air outlet communicating with the chamber of the kettle body 3. The rear end of the cylinder 43 has a rear cover 65 that seals the cylinder 43. A piston 42 is disposed inside the cylinder 43. The piston 42 is connected to a first push rod 45 that pushes the piston 42 to slide along the inner wall of the cylinder 43. The other end of the first push rod 45 passes through a first sealing sleeve 44 and is connected to a first handle 46.
[0029] In an embodiment, the pressure relief assembly 6 includes a rear cover 65 connected to one end of the third pipe 16 away from the mixing chamber 13. A movable second push rod 62 passes through the center of the rear cover 65. A sealing pin 64 that is movably inserted into the third pipe 16 to close the third pipe 16 is installed at the front end of the second push rod 62. The rear end of the second push rod 62 passes through the rear cover 65 and is connected to a second handle 61.
[0030] In an embodiment, a first elastic member 63 is sleeved on the outer wall of one end of the second push rod 62 located inside the nozzle 1. A ring-shaped protrusion for clamping one end of the first elastic member 63 is provided on the second push rod 62. The other end of the first elastic member 63 is clamped to the inner wall of the rear cover 65. When relieving pressure, by pulling the second push rod 62, the second push rod 62 drives the sealing pin 64 to disengage from the third pipe 16, so that the pressure in the chamber of the kettle body 3 enters the mixing chamber 13 through the hose 15 and the second pipe 14 and overflows through the third pipe 16. The first elastic member 63 on the second push rod 62 provides the force for the sealing pin 64 to reset, ensuring that when pressure relief is not required, the sealing pin 64 is inserted into the third pipe 16 to keep the third pipe 16 in a sealed state.
[0031] In an embodiment, a handle 31 is installed on the side wall of the kettle body 3.
[0032] In an embodiment, one end of the bottom of the second pipe 14 is connected to a hose 15, and the other end of the hose 15 contacts the bottom wall of the chamber of the kettle body 3.
[0033] In an embodiment, a liquid adding port adjacent to the opening is provided on the top wall of the kettle body 3. The liquid adding port is communicated with the chamber of the kettle body 3, and a bottle valve 5 is hermetically connected to the top end of the liquid adding port.
[0034] The working principle of the small fungicide sprayer based on the first embodiment is as follows: When in use, various reagents are added into the hollow chamber of the kettle body 3 through the liquid adding port on the top wall of the kettle body 3, and the pressurizing assembly 4 is used to pressurize the chamber of the kettle body 3. The pressurizing assembly 4 specifically includes a cylinder body 43 hermetically connected to the kettle body 3. A piston 42 and a first push rod 45 are arranged in the cylinder body 43. By pushing the first handle 46, the first push rod 45 drives the piston 42 to slide in the cylinder body 43, thereby compressing the air between the cylinder body 43 and the chamber of the kettle body 3 and injecting the air into the chamber, so that the pressure in the chamber increases.
[0035] Under the action of pressure, various reagents in the kettle body 3 enter the spherical mixing chamber 13 of the spray head 1 through the hose 15 and the second pipeline 14 and collide with each other, so as to fully mix various reagents without stirring and form a fungicide.
[0036] When spraying the fungicide, by pressing the long handle 73 end of the lever 7, the long handle 73 drives the short handle 71 to move with the mounting seat 11 as a hinge point of the lever, so that the short handle 71 pushes the nozzle 2 to gradually disengage from the first pipeline 12, and the groove on the nozzle 2 is communicated with the first pipeline 12. Thus, the fungicide fully mixed in the mixing chamber 13 can be sprayed out from the groove of the nozzle 2 through the first pipeline 12 under the action of pressure. The second elastic member 72 between the long handle 73 and the spray head 1 provides the power for the lever 7 to reset, so as to control the insertion depth of the nozzle 2 into the first pipeline 12. When the long handle 73 is in the reset state, the nozzle 2 is completely inserted into the first pipeline 12, and the first pipeline 12 is closed to prevent the fungicide from spraying out.
[0037] A handle 31 is installed on the side wall of the kettle body 3, which is convenient for the user to hold the sprayer for operation.
[0038] The above specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
