[0032] Example 1

[0033] The compressed air sprayer disclosed in this embodiment is shown in FIG. Figure 1-2 ,include:

[0034] A tank body 1, wherein the tank body 1 is provided with a feed inlet 2 and a discharge port 3, wherein the feed inlet 2 is used to input liquid medicine into the tank body 1;

[0035] The tank body 1 is used as a container, and a feed port 2 and a discharge port 3 are arranged on the tank body 1. The feed port 2 is used to input the drug liquid so that the drug liquid is stored in the tank body 1, and the discharge port 3 is used to output the drug liquid in the tank body 1.

[0036] A gas pipeline 4, wherein the gas pipeline 4 is laid on the inner bottom of the tank body 1;

[0037] The gas pipeline 4 is used to transport gas to the tank body 1. The gas pipeline 4 is laid at the bottom of the tank body 1 to facilitate the gas in the gas pipeline 4 to be output from the bottom of the tank body 1 to the top of the tank body 1, so that the entire inner cavity of the tank body 1 is evenly filled with gas.

[0038] A compressed gas storage tank 5 is connected to the gas pipeline 4, and the gas pipeline 4 is provided with a plurality of exhaust holes 6.

[0039] The compressed gas storage device 5 stores compressed gas, and the compressed gas is output through the gas transmission pipeline 4, wherein the gas transmission pipeline 4 is provided with a plurality of exhaust holes 6.

[0040] By opening the exhaust hole 6 on the gas pipeline 4, the exhaust hole 6 can evenly disperse the gas on the gas pipeline 4, so that the liquid medicine in the tank body 1 can be evenly dispersed.

[0041] The compressed gas storage device 5 transmits compressed gas to the inner cavity of the tank body 1 through the exhaust hole 6 on the gas transmission pipeline 4 , and the compressed gas mixes the liquid medicine in the tank body 1 and drives the mixed liquid medicine to be output from the discharge port 3 .

[0042] When in use, the compressed gas storage device 5 transmits the compressed gas therein to the inner cavity of the tank body 1, and the compressed gas granulates and vaporizes the liquid medicine in the tank body 1. Driven by the compressed gas force, the liquid medicine in the tank body 1 is sprayed outside the tank body 1 in the form of particles, thereby achieving the effect of spraying medicine by the sprayer.

[0043] In this embodiment, the gas delivery pipeline 4 includes a tube body, one end of which is a sealed end, and the other end is connected to the compressed gas storage tank 5. The tube body is provided with a plurality of exhaust holes 6 arranged along its length direction, and each exhaust hole 6 is arranged upward. A check valve 13 is provided on the tube body, and the check valve 13 is arranged on the outside of the tank body.

[0044] Since one end of the tube body is a sealed end and a plurality of exhaust holes 6 are provided on the tube body, the compressed gas can only be discharged from the exhaust holes 6 on the tube body, so that the gas can be evenly dispersed upward from the bottom of the tank body 1. The check valve 13 is used to prevent the liquid medicine in the tank body from flowing back to the compressed gas storage device.

[0045] Furthermore, a plurality of gas pipelines 4 may be laid at the bottom of the tank body 1 so that the inner bottom surface of the tank body 1 is provided with exhaust holes 6, thereby improving the uniformity and effect of compressed gas output.

[0046] In this embodiment, the discharge port 3 is arranged at the top of the tank body 1 .

[0047] The purpose of arranging the discharge port 3 at the top of the tank body 1 is that since the exhaust holes 6 are all arranged on the inner bottom surface of the tank body 1, arranging the discharge port 3 at the top of the tank body 1 makes it easier for the vaporized liquid medicine to be quickly sprayed out along the spraying direction of the liquid medicine, and also allows the liquid medicine to have sufficient time to mix in the tank body 1.

[0048] In this embodiment, the discharge port 3 is connected to a spraying pipe 12 , and the discharge port 3 sprays the medicine to the target crop through the spraying pipe 12 .

[0049] The liquid medicine is directed to the target crops through the medicine spraying pipe 12 .

[0050] In this embodiment, the feed port 2 is provided with a pressure cover 7 .

[0051] When the feeding is completed, the pressure cover 7 is closed so that the gasified liquid medicine is only discharged from the discharge port 3.

[0052] In this embodiment, the compressed gas storage device 5 includes a gas storage tank 51, and the gas storage tank 51 is connected to an air pump 52 and a pressure regulating valve 53.

[0053] The air pump 52 is also connected to a 12V battery, and the 12V battery drives the air pump 52 to input gas into the gas tank 51 . The output pipeline is connected to the gas tank 51 through the pressure regulating valve 53 .

[0054] When in use, the air pump 52 can be driven by the 12V storage battery, so that the air pump 52 inputs gas to the gas storage tank 51 to achieve the function of storing compressed gas. At the same time, the pressure of the compressed gas output is controlled by the pressure regulating valve 53 to ensure the driving force of the compressed gas. This embodiment can drive the compressed gas storage using a 12V storage battery, avoiding the problem of the prior art requiring high voltage driving.

[0055] In this embodiment, the pressure provided by the pressure stabilizing valve 53 is 4 to 6 atmospheres. The pressure of 4 to 6 atmospheres is relatively low, so the pressure of the compressed gas can be adjusted with relatively low energy consumption, which has an energy-saving effect.

[0056] In this embodiment, the tank body 1 is disposed on a frame 8 , one end of the frame 8 is connected to the compressed gas storage container 5 , and the other end of the frame is provided with a storage shaft 9 , and the medicine tube 12 is wound around the storage shaft 9 .

[0057] The tank body 1 is arranged on the vehicle frame 8, so that the components are arranged more compactly, which is convenient for realizing vehicle-mounted performance and convenient for rapid spraying.

[0058] In this embodiment, the tank body 1 is provided with a pressure relief valve 10 .

[0059] When the gasified liquid medicine is not needed, the pressure relief valve 10 can be opened.

[0060] In this embodiment, a closable and openable sewage outlet 11 is provided at the bottom of the tank body 1 .

[0061] The sewage outlet 11 is convenient for quickly discharging the sludge in the tank body 1 .

[0062] In this embodiment, the pressure provided by the pressure stabilizing valve 53 is 4 to 6 atmospheres, and the tank body 1 withstands a pressure of 6 to 9 atmospheres. The pressure stabilizing valve and the pressure-resistant function of the tank body can better realize the spraying of medicine, and can also save energy consumption.
