Further, hairbrush is surrounded by positioned at the sand jet outlet in the head body, hairbrush can prevent from spraying
Sand material disperses during sand.
Further, the 3rd chamber is in hourglass shape, and sand material is by the speed of the 3rd chamber with the mouth of the 3rd chamber
Footpath changes and changed, and speed first diminishes becomes big afterwards so that sand material obtains higher jet velocity and sprayed.
Further, the aperture of first taper hole is less than the aperture of the second taper hole, and sand material after first chamber by accelerating
Into second chamber.
Further, the aperture of first straight hole is less than the aperture of the second straight hole.
Further, the sand-feeding tube is obliquely installed towards sand jet outlet direction, and angle of inclination is 120-135 degree.
Further, the central axis of the first chamber, second chamber and the 3rd chamber is on the same line.
Further, the support body is circular hollow frame.
The present invention has the advantages and positive effects of：This nozzle structure is by hybrid frame sand material in first chamber
Mixing, grinding, and by being sprayed after second chamber and the 3rd chamber rectification, sandblasting quality is ensure that, prevent sand material from luming, sand material
Changed by the speed of the 3rd chamber with the bore of the 3rd chamber and change, speed first diminishes becomes big afterwards so that sand material obtains
Higher jet velocity sprays so that sandblasting effect is more uniform, and hairbrush can prevent that sand material disperses during sandblasting, has structure letter
Single, easy to use, the advantages that sandblasting effect is good.

Embodiment
The specific embodiment of the present invention is elaborated below in conjunction with the accompanying drawings.
As illustrated in fig. 1 and 2, a kind of nozzle structure, including air inlet pipe 1, sand-feeding tube 2 and head body, in the shower nozzle sheet
The front end of body is provided with sand jet outlet 3, and air admission hole is provided with the rear end of the head body, and it is empty that sandblasting is provided with the head body
Chamber, the sandblasting cavity include first chamber, second chamber and the 3rd chamber 15, the first chamber, second chamber and the 3rd
Chamber 15 is connected, and central axis is on the same line, and the first chamber is straight by the first taper hole 4 and first being mutually communicated
Hole 5 is formed, and the second chamber is made up of the second taper hole 6 being mutually communicated and the second straight hole 7, the aperture of first taper hole 4
Less than the aperture of the second taper hole 6, the aperture of first straight hole 5 is less than the aperture of the second straight hole 7, after sand material is by first chamber
Second chamber is accelerated into, the aperture of the 3rd chamber 15 is first shunk along the direction of sand jet outlet 3 to be expanded afterwards, the 3rd chamber 15
In hourglass shape, sand material is changed by the speed of the 3rd chamber 15 with the bore change of the 3rd chamber 15, after speed first diminishes
Become big so that sand material obtains higher jet velocity and sprayed, the air admission hole and first chamber that the air inlet pipe 1 passes through head body
Connection, into first chamber, gas injection makes to produce negative pressure in sandblasting cavity, and the sand-feeding tube 2 is arranged on the side wall of head body
On, connected with first chamber, the sand-feeding tube 2 is obliquely installed towards the direction of sand jet outlet 3, and angle of inclination is 120-135 degree, in institute
State and dismountable hybrid frame is provided with first chamber, the hybrid frame includes support body 8 and the rectification bar being disposed side by side on support body
