It is, of course, also possible to set up annular magnet 33 in the protective cover 32, and the coil 31 is wound in the ring
On shape magnet 33, to strengthen magnetic field.
It is exemplary in order to avoid damage of the liquid to the control assembly, can be by the control assembly located at described
The outside of housing 1, and open up on the housing 1 and opened for what the electric wire 34 of the connection control assembly and the coil 31 passed through
Mouthful.
In order that the spray apparatus spray job requirements, the nozzle for different spray nozzles 23 to adapt to different variables
Component 2 can include be articulated on the housing 1 rotating disk 21, be fixed on rotation control mechanism 22 in the rotating disk 21,
And the nozzle 23 of the axially spaced-apart setting along the rotating disk 21, and the nozzle 23 can be different types of nozzle 23, such as
This, the rotation control mechanism 22 rotating disk 21 can be driven to rotate with drive a nozzle 23 in the nozzle 23 with
The liquid outlet 15 docks, so as to meet different job requirements by changing different nozzles 23.It is understood that work as
When a nozzle 23 in the nozzle 23 docks with the liquid outlet 15, the liquid flowed out by the liquid outlet 15 will be by this
23 mouthfuls of ejections of nozzle of nozzle 23, and 23 mouthfuls of the nozzle is also formed the nozzle of the spray assembly.
In order to facilitate the installation rotating disk 21 and assembly and disassembly maintenance is carried out to the sprayer, exemplary, the housing 1
Can include ring-type body 12 and removably sealing cover in first end cap 11 and second at the both ends of the body 12
End cap 13, wherein the inlet 14 can be set on first end cap 11, on second end cap 13 described in setting
Liquid outlet 15, and the rotating disk 21 can be articulated on second end cap 13 by rotary shaft 35.
The rotation control mechanism 22 can include with the motor of the drive connection of rotating disk 21 and with the motor
The signal transmitting and receiving processor of electrical connection, in this way, the signal transmitting and receiving processor can receive control by wirelessly or non-wirelessly mode
Instruction, and control the motor to drive the rotating disk 21 to rotate according to the control command received, in order to operation people
Member is adjusted to the type of nozzle 23 of the sprayer, and job requirements are sprayed with the variable for meeting different in time.
It is understood that current atomization shape nozzle mainly includes three kinds of Hydrodynamic nozzle, aspiration nozzle and swirl nozzle
Nozzle.And the nozzle 23 in the sprayer in the present embodiment can use the Hydrodynamic nozzle, the aspiration nozzle and institute
State one or more of swirl nozzle, naturally it is also possible to use other kinds of nozzle.It is described in the nozzle of these three types
Hydrodynamic nozzle is drastically diminished in nozzle exit aperture by liquid and reached and caused high pressure as most common bleed type
Atomizing effect.Such nozzle atomization effect is moderate, and spreading of spray is larger, but easily loss；The aspiration nozzle side is provided with stomata
Enter for air, air mixes in nozzle interior with liquid, finally sprays the droplet wrapped up by bubble.Such nozzle can effectively be prevented
Drift, but it is larger to produce droplet；The swirl nozzle is improved by industrial coating nozzle, by liquid in built-in eddy flow groove
Be rotated up to atomizing effect.Such nozzle spray angle is relatively small, but atomizing effect is more satisfactory.
