Abstract
The invention discloses a pressure adjustment structure of a paint spray gun. The pressure adjustment structure is an adjustment ring body, and is connected with an outer spray nozzle and an inner spray nozzle of the paint spray gun in an assembly manner. The pressure adjustment structure comprises a ring groove, an oblique gas flow channel, a perforation penetrating through the adjustment ring body, a first gas flow channel, a second gas flow channel and a guide slope, wherein the first gas flow channel is communicated to the ring groove; the oblique gas flow channel is communicated to the second gas flow channel; the oblique gas flow channel is next to the guide slope; and the oblique gas flow channel declines to the perforation of the adjustment ring body. By means of a cyclone generated by the oblique gas flow channel of the adjustment ring body, the gas flow rate can be accelerated and can be uniform so as to reduce the energy consumption of an air compressor and shorten the time of waiting for inflating again.
Description
Technical field
The present invention relates to a kind of spray gun for paint parts, refer in particular to a kind of pressure adjusting structure of spray gun for paint.
Background technology
spray gun for paint is in use procedure, often can be inadequate because of the gas suction from the spray gun for paint ejection, cause paint to residue in spray gun for paint, cleaning comparatively bothers, gas flow rate is stablized and the generation sinuous flow not again, while easily making the constant aeration of air compressor machine be forced in spray gun for paint, and cause air compressor machine power consumption to reach greatly waste and inflate body always and enter time of spray gun for paint, just as TaiWan, China Patent data storehouse new patent, announce No. M400890: the rifle head flow dividing structure improvement of spray gun for paint, it is a kind of rifle head flow dividing structure improvement of spray gun for paint, espespecially a kind of flow dividing structure improvement design of spray gun for paint rifle head air-flow, it is that mainly the interior nose end for the inner nozzle air of rifle head is provided with one and revolves the shape groove, and for the nose end of outer nozzle air, be provided with groove, and by a vent diverter, press and be formed on described two air vents, the shape groove that revolves by the rifle head impels and guides the air of an air vent to enter vent diverter pivot place with helical form, make that air can complete equilibrium around spraying after inner nozzle, vent diverter is provided with a tap hole corresponding to another air vent, after guiding described gas flow hole to enter the flow-disturbing ring accumulation of vent diverter, periphery outflow along vent diverter reaches outer nozzle and sprays again, make airflow diversion and equalization stable air-flow and pressure, with the unbiased effect of the complete equalization in the cross section of spraying paint of guaranteeing that interior outer nozzle is controlled.
Above-mentioned front case has following shortcoming:
1. above-mentioned front case, because the gas via the vent diverter ejection is straight line in the air flow path of inner nozzle, easily causes gas to produce sinuous flow in inner nozzle, and the gas of inner nozzle ejection also has unstable and inhomogeneous situation.
2. above-mentioned front case is because the gas suction of inner nozzle ejection is not enough, easily cause paint can't be fully from sucking-off in the rifle body, and paint in the rifle body and can form solidifying body and clean difficult.
3. above-mentioned front case can cause air compressor machine to provide gas to unstable in the rifle body, and constantly aeration pressurization of air compressor machine, easily causes air compressor machine power consumption large, and the user need waste and waits for air compressor machine time of aeration pressurization again.
In view of this, the inventor is for not attaining perfect many disappearances and the inconvenience that causes on above-mentioned spray gun for paint structural design, and deeply design, and the active research improvement has a fling at and development and Design goes out this case.
Summary of the invention
The object of the present invention is to provide a kind of pressure adjusting structure of spray gun for paint, can reduce the power consumption of air compressor machine running load, relatively save electric power and the time of the aeration that again pressurizes, also can avoid the solidifying body that paints, in order to cleaning spray gun for paint.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of pressure adjusting structure of spray gun for paint, this pressure adjusting structure are an adjustment ring body, the outer nozzle of its assembly and connection spray gun for paint and inner nozzle;
This adjustment ring body includes a cannelure, an oblique flow channel, one, and to connect perforation, one first flow channel, one second flow channel and a water conservancy diversion of described adjustment ring body domatic, described the first flow channel is communicated to described cannelure, described oblique flow channel is communicated to described the second flow channel, and be in close proximity to a water conservancy diversion domatic on, described oblique flow channel is towards the perforation deflection of described adjustment ring body.
Described oblique flow channel is take the horizontal line that is parallel to described adjustment ring body as benchmark, and the oblique angle of described oblique flow channel is between 25 degree angles, degree angles to 55.
The oblique angle of described oblique flow channel is 40 degree angles.
After adopting said structure, the pressure adjusting structure of spray gun for paint of the present invention has following advantages:
1. the pressure adjusting structure of spray gun for paint of the present invention can form cyclone by oblique flow channel in inner nozzle, accelerate to reach gas the effect that flows, and air compressor machine is not needed as gas constantly is provided in a straight line flow channel, and the power consumption of air compressor machine running load also can be reduced, relatively can save electric power.
2. the pressure adjusting structure of spray gun for paint of the present invention, because form the cyclone that gas flow is accelerated in inner nozzle by oblique flow channel, makes air compressor machine not need aeration pressurization always, and can save the user and wait for that air compressor machine pressurizes time of aeration again.
3. the pressure adjusting structure of spray gun for paint of the present invention is by the cyclone that provides because of oblique flow channel, and the air-flow of spray gun for paint ejection is accelerated, and the generation of minimizing sinuous flow, and the cyclone suction that utilizes gas is with the paint sucking-off in spray gun for paint, paint residual quantity in spray gun for paint with reduction, and then avoid the solidifying body that paints, in order to cleaning spray gun for paint.
