Description

Technical Field

[0001] The utility model relates to the technical field of powder spraying, and particularly relates to a powder spraying device. Background Art

[0002] In recent years, garden trees, forest trees, grasslands and garden buildings have been increasingly damaged by termites. As social insects, termites are recognized as pests that are difficult to control in the world at present and have the living habit of nesting and living in groups.

[0003] At present, the main methods for controlling termites are contact killing and trapping with pesticides. Usually, powder is manually sprinkled at the places where termites appear or in the termite nests on trees and fruit trees, which has problems such as inaccurate use of pesticides, waste of pesticides, and poor control effect.

[0004] Currently, some manufacturers have also developed some termite powder sprayers. For example, the Chinese patent "Termite Control Powder Sprayer" with the publication number CN201308069Y discloses a termite control powder sprayer, which includes a medicine bottle. The upper end of the medicine bottle is provided with a bottle cap, and the bottle cap is provided with a medicine spraying pipe and an air inlet pipe. One end of the medicine spraying pipe is outside the bottle cap, and the other end is inside the medicine bottle. The height of the port at the end inside the medicine bottle is greater than half of the height of the medicine bottle. One end of the air inlet pipe is outside the bottle cap, and the other end is inside the medicine bottle. An air bag is connected to the port at the end outside the bottle cap. The medicine powder is put into the medicine bottle, and the air bag is squeezed by hand. The air inside the air bag enters the medicine bottle through the air inlet pipe to form pressure, and the medicine powder is sprayed out through the medicine spraying pipe under the action of the pressure.

[0005] The existing termite powder sprayers have the following deficiencies:

[0006] 1) The length of the existing medicine spraying pipe is fixed, and the length of the powder spraying pipe cannot be adjusted, resulting in that some termite nests at relatively far distances cannot be reached and the powder cannot be sprayed, and the use range is relatively limited.

[0007] 2) When the termite powder sprayer is used, the medicine powder needs to be filled into the inside of the medicine bottle, but not all the medicine powder inside the medicine bottle can be used each time. The medicine powder staying in the medicine bottle for a long time is easy to get damp and caked, resulting in problems such as the medicine spraying pipe being blocked by the caked medicine powder during the spraying process and the medicine not being able to be sprayed out.
