[0002] Biological control mainly relies on natural organisms or their metabolites to control harmful organisms. The "drug solution" used in biological control is actually biological liquid, which comes from nature and includes pathogenic microorganisms, insect pathogenic nematodes, plant-derived preparations, microbial metabolites, etc. The backpack sprayer uses a pump to extract the liquid from the medicine box and spray it out through a nozzle to achieve the purpose of spraying.

[0003] Solid wood furniture may be invaded by various pests during the production and use process, such as wood borers, termites, longhorn beetles, etc. These pests will not only destroy the wood structure, but also cause the wood to deteriorate and rot, affecting the appearance and service life of the furniture. Therefore, during the use of solid wood clamps, professional staff need to be regularly invited to carry out pest control. At present, most staff use backpack sprayers to spray pesticides regularly for pest control;

[0004] Most existing backpack sprayers are equipped with a liquid dosing mechanism to facilitate the quantitative addition and mixing of liquid medicine. However, when using such backpack sprayers to spray insecticides on solid wood furniture, there are still the following defects:

An installation groove 52 is provided on the negative pressure box 5 and located on the outer side of the opening. The sealing gasket 71 is inserted into the installation groove 52 and is snap-connected with the negative pressure box 5 to facilitate the installation or removal of the sealing gasket 71. When the sealing plate 51 blocks the opening, the sealing gasket 71 is in conflict with both the negative pressure box 5 and the sealing plate 51. During use, when the sealing plate 51 blocks the opening, the sealing gasket 71 is in conflict with both the negative pressure box 5 and the sealing plate 51, thereby increasing the fit between the negative pressure box 5 and the sealing plate 51.

[0043] In this embodiment, a collecting box 3 with an open top is inserted in the negative pressure box 5 and below the connecting pipe 152. Through the design of the collecting box 3, the filter plate 624 filters the insect bodies so that when the insect bodies remain in the negative pressure box 5, the insect bodies fall into the collecting box 3 and are collected by the collecting box 3, thereby facilitating the cleaning of the insect bodies.

[0044] In this embodiment, the quantitative dosing mechanism 2 includes a feed cylinder 21 fixedly mounted on the top of the medicine storage barrel 1, and a plurality of liquid inlet pipes 22 are installed in a circular array at the top position of the outer wall of the feed cylinder 21, and a medicine storage bottle 23 with an open top is fixedly mounted on the top of the liquid inlet pipe 22.

A scale 25 is fixedly mounted on the medicine storage bottle 23, and a valve 26 is installed on the liquid inlet pipe 22. When in use, the biological liquids to be mixed are respectively fed into the plurality of medicine storage bottles 23, and then the open ends of the medicine storage bottles 23 are blocked by the blocking covers 24. When adding biological liquid medicine to the medicine storage barrel 1 in a quantitative manner, opening valve three 26 can allow the biological liquid medicine to flow into the feed barrel 21 through the liquid inlet pipe 22, and then flow into the medicine storage barrel 1. By observing the scale 25, the amount of biological liquid medicine in the medicine storage bottle 23 can be known. Therefore, when adding biological liquid medicine to the medicine storage barrel 1 in a quantitative manner, the amount of biological liquid medicine added to the medicine storage barrel 1 can be known by observing the scale 25. Closing valve three 26 can block the liquid inlet pipe 22, thereby preventing the biological liquid medicine in the medicine storage bottle 23 from flowing into the feed barrel 21 through the liquid inlet pipe 22, thereby achieving the effect of quantitatively delivering biological liquid medicine into the medicine storage barrel 1.
