Knapsack type air atomizing sprayer

Abstract

The invention relates to the field of sprayers, and in particular to a knapsack type air atomizing sprayer, which comprises an air-liquid tank, two shoulder straps, an air source device, a power device, and an air-liquid atomizing spray head. The double shoulder straps are arranged on the rear side surfaces of the air-liquid tank. A liquid inlet is formed in the upper part of the air-liquid tank;a sealing cap or a sealing plug is arranged at the liquid inlet. An air inlet pipe and an air outlet pipe are connected with the upper part of the air-liquid tank, are communicated with the internal part of the air-liquid tank, and are arranged above a medicine liquid, wherein a check valve is installed on the air inlet pipe, and one end of the air inlet pipe away from the air-liquid tank is connected with the air source device, the air source device is connected with the power device, the air source device and the power device are jointly installed on the air-liquid tank, one end of the air outlet pipe away from the air-liquid tank is connected with the air inlet end of the gas-liquid atomizing nozzle. The liquid inlet end of the gas-liquid atomizing nozzle is connected with the air-liquid tank through a liquid outlet pipe, and the end of the liquid outlet pipe connected with the air-liquid tank is located at the lower part of the air-liquid tank. The sprayer has the advantages that it saves the medicine and has good spraying effect.

Description

technical field [0001] The invention relates to the field of sprayers, in particular to a knapsack air atomization sprayer. Background technique [0002] Sprayer is the abbreviation of spray equipment. A sprayer is a device that uses air suction to turn liquid medicine or other liquid medicine into mist and sprays it evenly on other objects. The existing sprayer has a single structure and a narrow range of use. Different types of sprayers only It can be used for special operations, and the use efficiency is not high. In addition, some of the existing traditional sprayers are sprayers powered by manual hand crank or battery-driven diaphragm pump. The failure rate of traditional sprayers is high, which affects the efficiency of spraying. Moreover, the range of traditional sprayers is relatively short, generally about 3 meters , the coverage area of ​​medicinal liquid is little, and work efficiency is low, waste medicinal liquid, can not reach the effect of spraying medicine f...

[0002] Sprayer is the abbreviation of spray equipment. A sprayer is a device that uses air suction to turn liquid medicine or other liquid medicine into mist and sprays it evenly on other objects. The existing sprayer has a single structure and a narrow range of use. Different types of sprayers only Can be used for specialized operations, and the efficiency is not high

In addition, some of the existing traditional sprayers are powered by manual manual or battery-driven diaphragm pumps. The failure rate of traditional sprayers is high, which affects the efficiency of spraying. Moreover, the range of traditional sprayers is relatively short, generally about 3 meters. , the coverage of the liquid medicine is small, the work efficiency is low, and the liquid medicine is wasted. It cannot achieve the effect of complete spraying on tall fruit trees, and the spraying effect on hidden places is not good.

Although the vehicle-mounted sprayer can have a better spraying effect, it is bulky, heavy, inconvenient to use, not conducive to the use in hilly and mountainous areas, and the cost is high, so it is not suitable for farmers
