[0035] Example
[0036] Due to the coverage problem and liquid penetration problem of a single spray head, the traditional spray device generally needs to be equipped with multiple spray heads, generally about 11, and because of the need to ensure permeability, a large amount of antifreeze and dust suppressant spraying is generally required. Therefore, it also has certain problems.

[0042] Furthermore, the nozzle 30 includes a water inlet 31, a suction chamber 32, a diffuser 33 and a nozzle 34. The suction chamber 32 is connected to the water inlet 31 and the diffuser 33. The nozzle 34 is connected to the diffuser 33 and is located on a side away from the suction chamber 32. A channel 35 is extended to form a side of the diffuser 33. The channel 35 is connected to the air inlet 36. The water inlet 31 is connected to the water pipe 51, and the air inlet 36 is connected to the air pipe 52. The water inlet 31 gradually narrows in diameter near the suction chamber 32 along the water outlet direction.

Therefore, there is no need to equip the same number of nozzles 30 as the traditional spraying device. Instead, the number of nozzles 30 can be reduced by nearly one third, and the effect is equivalent or even better.
[0046] Specifically, sealing end covers 41 are provided at both ends of the storage barrel;
