Example 4
Embodiment 4 is different from embodiment 1 in that, as shown in fig. 8, a mounting plate 181 is fixed on the first connecting member 18, and the hollow cone-shaped spray head 2 is connected with the mounting plate 181 through a swinging spring 66, that is, the hollow cone-shaped spray head 2 is elastically connected. The triangular rods 65 are fixed on the outer peripheral surface of the hollow conical spray head 2, the triangular rods 65 are made of plastic, the cross sections of the triangular rods 65 are triangular, and the triangular rods 65 are arranged along the radial direction of the hollow conical spray head 2.
The mounting plate 181 is provided with a driving component, and the driving component is mainly used for forcing the hollow conical spray head 2 to swing reciprocally, in other embodiments, the driving component can be a telescopic structure such as a cylinder, an electric push rod, etc., and the telescopic end of the telescopic structure collides with the hollow conical spray head 2 so as to force the hollow conical spray head 2 to swing reciprocally.

When a large amount of dust burst occurs in the construction area, as the water droplet quantity of the water mist area 201 is limited, the adsorption of a large amount of dust is difficult to quickly complete, so that the electromagnet 62 can be switched on and off once, the metal ball 63 is forced to move towards the triangular pole 65 by the magnetic force of the electromagnet 62, the metal ball 63 collides with the triangular pole 65, the electromagnet 62 is powered off, the metal ball 63 is quickly pulled back by the elastic force of the reset spring 64, so that the metal ball 63 collides with the triangular pole 65 in real time, and the collision force is converted into kinetic energy for forcing the hollow conical spray head 2 to swing reciprocally.
Therefore, the hollow cone spray boundary zone 202 is reciprocally offset by a large displacement along with the reciprocal oscillation of the hollow cone spray head 2, that is, the dust fall range of the hollow cone spray boundary zone 202 is greatly increased, so as to form a large water droplet area 203 with a certain area.
In addition, the forming of the large water droplet area 203 also compresses part of the area of the water mist area 201, that is, the area ratio of the large water droplet area 203 to the water mist area 201 is changed (see fig. 9), so that small water droplets with smaller area can primarily adsorb fine dust in a burst large amount of dust, and large water droplets with larger area can quickly capture a large amount of dust, so that the dust is controlled at a local position, and the diffusion of the dust is reduced.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
