I. PRINCIPAL FUNCTIONS
This sprayer is a new generation of highly
efficient sprayer comfortable for back-
mounting, convenient to operate, uniform in
atomization in addition to its economical and
safe advantages. This Sprayer is applicable for
pest-controlling of various crops, flowers and
garden plants cleaning of public places as well
as hygiene and disease control of fowl and
livestock houses.
II. STRUCTURE, OPERATING PRINCIPLES
AND FEATURES
STRUCTURE:
This Sprayer consists of five units: a tank, a
pump, a spraying unit (tube, switch, a spray
boom, and a spray head), a rock bar unit and
a strap.
PRINCIPLES:
The leather cup moves up/down in the pump
cylinder due to the swinging of rock bar unit
to produce a pressure difference between the
inside and outside of the pump which will drive
the valve sheet to open and close so as to
pump the mixture into the chamber which will
be sprayed like fog through the spraying unit.
FEATURES:
1. The tank is ergonomically designed to
imitate the curve of human back to ensure
close contact with and comfortable carrying
on the back. The built-in chamber offers
compact and leak-free structure.
2. Come with a piston pump to ensure simple,
safe, leak-free and labour-saving operation.

3. It comes with a hold-and-release switch
to allow flexible, leak-proof and sound
operation, ideal for both spot spraying and
continual spraying.
4. A variety of nozzles are available
depending on the practical demands to
attain optimum spraying result.
5. The whole unit is made of premium
materials to ensure high resistance to
acid, base and corrosion, in addition to
proven air-tightness and durability.
