Embodiment 1

[0033] A kind of injection-suction type medicine mixer of present embodiment, as figure 1 - As shown in -5, it includes an outlet pipe 1, a first rubber gasket 2, a mixing tube 3, a core pipe 4, a first rubber ring 5, a water inlet pipe 6, a second rubber gasket 7, and a third rubber gasket 8 , feeding tube 9 and the second rubber ring 10. In the following, a concrete description will be made by taking only one core tube in the mixing tube as an example.

[0034] In this embodiment, the mixing tube 3 is a three-way tube, and there is a through hole along the axial direction of the mixing tube 3. The two sides of the through hole are threaded. The inner diameter of the threaded hole is larger than the inner diameter of the middle light hole, and the light hole is used to install the core tube. 4. A flange is processed in the middle of the water inlet pipe 6, and the side of the flange can be used as a reference for assembling the mixing pipe, the core pipe, and the outlet pip...

Embodiment 2

[0039] Present embodiment except following feature other structures are with embodiment 1:

[0040] Such as Figure 6 As shown, the present embodiment provides a nebulizer based on the medicine mixer shown in Embodiment 1, the nebulizer includes a water tank 11, a medicine box 17, a nozzle 15, a piezoelectric pump 16, a centrifugal pump 14, and the above-mentioned medicine mixer 13, In the drug mixer 13, the water inlet pipe is connected with the water tank 11 through a pipeline. In order to facilitate flow regulation, an adjustable throttle valve 12 is provided on the pipeline between the centrifugal pump 14 and the water tank 11, and the drug inlet pipe in the drug mixer 13 Connected to the piezoelectric pump 16, the piezoelectric pump 16 is connected to the medicine box 17, the outlet pipe in the drug mixer 13 is connected to the inlet of the centrifugal pump 14, and the outlet of the centrifugal pump 14 is connected to the nozzle 15 through a soft hose, and each connection...

Abstract

The invention discloses an injection-suction type medicine mixer, a sprayer and a spraying method of the sprayer. The medicine mixer comprises a water inlet pipe, a medicine inlet pipe, a mixing pipe and a flow discharging pipe, wherein the water inlet pipe, the mixing pipe and the flow discharging pipe are sequentially connected in a sealing manner; a plurality of core tubes are arranged in the mixing pipe; a plurality of annular grooves are formed in the outer surface of each core tube; an annular cavity is jointly formed between the outer surface of each core tube and the inner wall of the mixing pipe; one of annular grooves is opposite to one of medicine inlet holes in the mixing pipe; a plurality of through holes are formed in the circumferential direction of other annular grooves and are used for allowing liquid medicine injected into the annular cavities by the medicine inlet pipe to flow into the core tubes; the liquid medicine enters the annular grooves opposite to the medicine inlet holes from the medicine inlet pipe and flows into other surrounding annular grooves through the annular cavities, and enters into the core tubes through the through holes in the bottoms of the annular grooves under the action of a suction force of an external water pump, so that uniform mixing of the liquid medicine is realized; multiple medicines can be mixed by adopting multiple core tubes; the injection-suction type medicine mixer has the advantage of simple and compact structure.

Description

technical field [0001] The invention relates to the field of plant protection machinery research, in particular to an injection-suction type drug mixer, a sprayer and a spraying method thereof. Background technique [0002] With the rapid development of industrialization, people's living environment is constantly polluted, and various viruses continue to break out all over the world, and they are getting worse day by day. In addition, due to global warming, the survival rate of pests in winter has increased, and the next year's pests and diseases will become more serious. Considering environmental and food safety factors, the requirements for pest control are also stricter. The control of pests and diseases requires a large amount of pesticide spraying, but the pesticide residues in agricultural and sideline products are required to meet the requirements of green and safe food. Therefore, it is imperative to develop new, efficient, safe, and low-pollution sprayers. The most ...
