It collides with gas-liquid mixed chamber, and then greatly improves atomizing effect.
As a kind of preferred embodiment of the utility model, the bore of the jet hole by neighbouring gas-liquid mixed chamber one end extremely
Successively decrease successively one end far from gas-liquid mixed chamber.
As a kind of preferred embodiment of the utility model, it is axial arranged that the connecting tube favours barral of a gun, angle of inclination
It is 10 °~20 °.
As a kind of preferred embodiment of the utility model, expansion joint is provided on the barral of a gun；It can compensate for drawing because of temperature difference
The stress risen.
As a kind of preferred embodiment of the utility model, temperature sensor is provided in the chuck；Monitoring folder can be achieved
The temperature of medium in set.
The beneficial effects of the utility model are, a kind of spray gun, which passes through, is arranged heating and heat-insulating device so that material is defeated
It passes through temperature in journey and remains inconvenient, avoid material crystallisation by cooling from blocking spray gun, and the utility model has simple in structure, atomization effect
The good feature of fruit.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of spray gun of the utility model.
Specific implementation mode
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.It can manage
Solution, embodiment described herein are used only for explaining the utility model, rather than the restriction to the utility model.
It please refers to shown in Fig. 1, Fig. 1 is a kind of structural schematic diagram of spray gun of the utility model.
In this present embodiment, a kind of spray gun, including barral of a gun 1 and atomizer 2, the top of the barral of a gun 1 are provided with expansion
Section 3, barral of a gun 1 include materail tube 4 and the chuck 5 being sheathed on outside materail tube 4, are provided with temperature sensor in the chuck 5, press from both sides
Set 5 top be provided with circulatory mediator import 6, circulatory mediator outlet 7, and chuck 5 in by partition board separation be provided with first passage,
The top of second channel, the first passage is connected with circulatory mediator import 6, and its underpart is connected with the lower part of second channel
Logical, the top of the second channel is connected with circulatory mediator outlet 7, and the atomizer 2 includes gas-liquid mixed chamber, the gas
The right end of liquid mixing chamber is connected with inlet 10, and left end is connected with jet hole 9, and air inlet is provided in gas-liquid mixed chamber
Mouthful, the inlet 10 favours gas-liquid mixed chamber arrangement, and the axis of the axis of inlet 10 and jet hole 9 is not the same as always
On line, the bore of the jet hole 9 is successively decreased successively by right end to left end, and the barral of a gun 1 passes through connecting tube 8 and 2 phase of atomizer
Even, the upper end of the connecting tube 8 is connected with the discharge port of materail tube 4, and lower end is connected with the inlet 10 of atomizer 2
Logical, connecting tube 8 favours that barral of a gun 1 is axial arranged, and angle of inclination is 15 °.
