The purpose of this arrangement is that the spray bottle structure can spray the powder out through the nozzle by air pressure through the assembly of the air pumping assembly, which is convenient to use and replaces the traditional spraying at an inclined angle, thereby improving the uniformity of powder spraying.

[0005] In the aforementioned spray bottle structure, the inflating assembly includes an air cylinder, a sealing plug, a push-pull block, a piston, and a connecting rod. One end of the air cylinder is threadedly connected to the end of the first connector, and the other end of the air cylinder is threadedly connected to the sealing plug. The piston is slidably connected to the interior of the air cylinder, and the connecting rod is fixedly installed at the center of the piston. The connecting rod passes through the sealing plug and is fixedly installed with the push-pull block. The purpose of this arrangement is to pull the connecting rod to move through the push-pull block, and the piston is pulled by the connecting rod to move through the connecting rod, so that the movement of the piston draws external air into the air cylinder.

[0006] In the above-mentioned spray bottle structure, a first one-way air valve is fixedly installed on the top of the first connector. The purpose of this arrangement is to pressurize the gas in the gas cylinder into the interior of the drug storage cartridge through the first one-way air valve, thereby changing the air pressure inside the drug storage cartridge.

[0007] In the above-mentioned spray bottle structure, a sealing ring is provided at the connection between the sealing cover and the medicine storage cartridge, so as to improve the sealing performance of the connection between the sealing cover and the medicine storage cartridge.

[0008] In the above-mentioned spray pot structure, the angle between the spray head and the conduit is between 120° and 135°. The purpose of such setting is to determine the angle of the spray head.

[0009] In the above-mentioned spray bottle structure, a transparent observation window is fixedly installed on the front of the drug storage cartridge, and the side of the transparent observation window is engraved with evenly distributed scale lines. The purpose of this arrangement is to facilitate observation of the amount of medicine inside the drug storage cartridge through the transparent observation window.

[0010] Compared with the existing technology, the advantages of the spray bottle structure of the utility model are: the spray bottle structure sprays the powder through the nozzle through the air pressure through the assembly of the air pump component, which is convenient to use and replaces the traditional spraying at an inclined angle, thereby improving the uniformity of the powder spraying. When in use, the pressurization of our spray bottle is carried out in the form of an air pump, with a large air volume, high pressure, and easy to use pressurization operation.
