The air compressor 2 can adopt a small size with lower power, and inhales air from the air inlet 21 for compression, and then outputs the compressed air from the air compressor pipe 22. The bottom of the air compressor 2 is connected to a base 23, and a plurality of upper shock absorbers 24 are arranged between the air compressor 2 and the base 23, and a plurality of lower shock absorbers 25 are arranged between the bottom of the base 23 and the bottom wall 11 of the chassis 1 to reduce the noise generated by vibration.

The pump 3 is arranged inside the chassis 1. The pump 3 connects the external liquid pipeline (not shown) from the liquid inlet pipeline 31 to inhale the liquid, and the liquid can be water, pesticide or insect repellent, and then controls the flow rate to output the liquid from the liquid outlet pipeline 32. The liquid outlet pipeline 32 is connected to an air inlet pipe 33, and the air inlet pipe 33 is connected to a check valve 34 to attract external air to enter the liquid outlet pipeline 32 through the air inlet pipe 33 and the check valve 34.

The two-fluid nozzle 4 is arranged in cooperation with the nozzle holder 43 inside the chassis 1. As shown in Figures 6 to 12, the general or ultrasonic two-fluid nozzle 4 includes a nozzle body 41 correspondingly connected to one end of a mixing tube 42, an air inlet 421 at the other end of the mixing tube 42 is connected to the output end of the air pressure pipeline 22, and a liquid inlet 422 around the mixing tube 42 is connected to the output end of the liquid outlet pipeline 32. The two corresponding frame plates 431 and 432 of the nozzle frame 43 are fixed to the inner surface of the side wall 12 of the chassis 1. The nozzle frame 43 is pivoted with a collar 44 in the groove 433. The two fluid nozzles 4 are radially penetrated and fixed in the radially opposite through holes 441 of the collar 44 (see Figure 9). The nozzle body 41 extends outward from the collar 44, the nozzle frame 43 and the corresponding side wall 12 of the chassis 1 to set the two fluid nozzles 44. The tilt angle of the fluid nozzle 4 is controlled by the clamping piece 434 on both sides of the corresponding sleeve ring 44 in the middle section of the two frame plates 431 and 432 of the nozzle frame 43. The chassis 1 is provided with a positioning bolt 45 that locks the corresponding screw hole 435 in the middle section of the two frame plates 431 and 432 of the nozzle frame 43 in the positioning hole 122 of the side wall 12 to control the clamping piece 434 to clamp or loosen the sleeve ring 44 to adjust the angle.

The liquid can also be controlled to be output intermittently according to demand to achieve intelligent operation control effect.

When the fluid sprayer of the invention is actually operated, the small low-power air compressor 2 is installed in the accommodation space 16 of the chassis 1. The air compressor 2 sucks air from the air inlet 21 to compress it, and then outputs the compressed air from the air pressure pipe 22. The pump 3 sucks liquid from the liquid inlet pipe 31, and then controls the flow rate to output the liquid from the liquid outlet pipe 32. The air pressure pipe 22 outputs the liquid. The compressed air is sent into the mixing tube 42 of the two-fluid nozzle 4, and the compressed air attracts the liquid from the liquid outlet pipe 32 into the mixing tube 42, so that the compressed air mixes with the liquid in the mixing tube 42 and sprays outward from the nozzle body 41, thereby being able to stably control the spray angle and reduce the power specification of the air compressor 2, making the fluid sprayer more convenient to move around.

When the fluid sprayer is performing the spraying operation, the pump 3 can be adjusted to control the delivery of low flow or trace liquid, and the small low-power air compressor 2 outputs at full capacity, allowing the compressed air to attract low flow or trace liquid into the mixing pipe 42 for full mixing, and at the same time attract external air through the air inlet pipe 33 and the check valve 34 to enter the liquid outlet pipeline 32 and the mixing pipe 42, which can prevent the liquid outlet pipeline 32 from suffocating, allowing the two-fluid nozzle 4 to maintain a stable spray angle.
