Specific embodiment
With reference to the accompanying drawings and detailed description, the utility model is described further.
As shown in Figs 1-4, a kind of spin rotary-column type spray head, including spray column 1, swivel head 2 and pedestal 3.Swivel head 2 is fixed on
The lower part of spray column 1, inner ring and 1 outer wall of spray column of swivel head 2 are sealedly and fixedly connected.Cylindrical type through-hole 30 is offered inside pedestal 3,
Swivel head 2 is mounted in cylindrical type through-hole 30 and can make circumferentially to rotate freely, the outer wall of swivel head 2 and the wall of cylindrical type through-hole 30
There is certain gap, swivel head 2 is all made of PVDF material with pedestal 3 and is made between face.The top of pedestal 3 extends shape inwardly
At the snap ring 31 for carrying out axial limiting to swivel head 2, the lower part of cylindrical type through-hole 30 is equipped with internal screw thread 301.
The spray channel 10 towards bottom is offered inside spray column 1, is round hemisphere 11, round hemisphere at the top of spray column 1
Several spray orifices 111 are uniformly provided on body 11, the diameter of spray orifice 111 is 0.3mm, and spray orifice 111 is perpendicular to round hemisphere 11
Wall surface.1 side wall of spray column offers three groups of holes Dou 12 for leading to spray channel 10 along its length, and the diameter in the hole Dou 12 is 1mm,
The each group of hole Dou 12 on 1 length direction of spray column between be divided into 5mm, the quantity in each group of hole Dou 12 is 10, any two groups of phases
It is staggeredly located out between the hole Dou 12 even.The hole Dou 12 is angularly disposed, and the central axes in the hole Dou 12 and the central axes of spray channel 10 do not have
There is intersection point.Any one group of hole Dou 12 is axisymmetricly distributed around the central axes of spray channel 10, and the hole Dou 12 and spray column 1 are horizontal
The tangent line in section is in 45 ° of angles, and the hole Dou 12 is towards on the outside of tangent line.
The working principle of the utility model are as follows: it is spraying to enter through spray channel 10 and sprayed by each hole Dou 12 and spray orifice 111,
Since the tangent line of the hole Dou 12 and 1 horizontal cross-section of spray column is in 45 ° of angles, make spray column 1 inverse by generated deboost by spraying
Outgassing direction rotation, and then spraying equably spray attachment on the surface of furniture or various wood-based plates is formed into formaldehyde absorption coating.
Swivel head 2 and pedestal 3 are all made of PVDF material and are made, and PVDF material has self-lubricating capacities and frictional force very little, are conducive to revolve
Rotary head 2 rotates in the cylindrical type through-hole 30 of pedestal 3.By adjustable spraying amount or the size of air pressure, the rotation of spray column 1 can control
Rotary speed, so that the pollutant for film surface of preferably going out and the dirt in reduction spray orifice 111 and the hole Dou 12 are stifled.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
