Description

Improvement of air flow path of paint gun body

This creation is the first of its kind to improve the air flow path of the gun body of a paint spray gun, especially a structural improvement design of the air flow channel of the paint gun. Its main reason is that the main air channel of the gun body is divided into A flow channel for the inner nozzle and a flow channel for the outer nozzle, and an air flow adjustment group is provided on the outer nozzle flow channel, which is located near the side of the gun head, so as to adjust the air flow rate of the outer nozzle, providing a good operation for the user to operate the air flow adjustment group Space, and reduce the difficulty of gun body processing, and improve airflow efficiency and stability, thereby improving the better spraying performance of the gun.

The conventional paint spray gun, as shown in the Republic of China Patent Certificate No. 299601, has a considerable distance between the airflow adjustment group and the gun head, which is widely used in the currently available paint spray guns, but still has the following shortcomings and is not practical :

1. Affected by the structure of the gun body, the cross-sectional area of the flow channel is quite limited, and the flow rate is also limited accordingly.

2. The forming tool for processing is slender, which is easy to shake and break during processing, which affects the processing accuracy and yield, and causes unnecessary waste.

3. When adjusting the airflow, the user can hold the gun with one hand and directly adjust the required air flow with the thumb of the hand, but there is no expected effect in use. The adjustment will be made with the other hand, so the working space is often insufficient.

After collecting various opinions from the market, the creators have accumulated many years of experience in the industry to solve the above-mentioned habits that are not practical. The creators have created the original creation after many sample trials and experiments.

That is to say, this creation provides an improvement of the air flow path of the spray gun gun body, especially a structural improvement design of the air distribution flow path of the spray gun. Its main purpose is that the main air channel of the gun body passes through the paint of the gun body. At the entrance, the flow is divided into an inner nozzle flow channel and an outer nozzle flow channel, and an air flow adjustment group is provided on the outer nozzle flow channel, located near the side of the gun head, so as to adjust the air flow rate of the outer nozzle to provide the user to operate the air flow Adjust the good operating space of the group, and reduce the difficulty of the gun body processing, and improve the airflow efficiency and stability, thereby improving the spraying performance of the spray gun.

The second picture is a schematic cross-sectional view of this creative combination.

The third figure is the first schematic diagram of the gun body flow channel section of this creation.

The fourth figure is the second schematic diagram of the gun body flow channel section of this creation.

As shown in the first to fourth figures, this creative department includes: a gun body group 10, a gun body inside the gun head end 11, sleeved with a splitter 12, and pivot An inner nozzle 13 is provided, and an outer nozzle group 14 is screwed on the outer side; a main channel 15 is provided at the upper end of the gun body, one end of which communicates with the handle air intake 16 and the other end extends to the paint inlet 17 and passes through the paint inlet At point 17, there are two flow paths to the nozzle head, one is the inner nozzle flow channel 18, the other is near the gun head side is the outer nozzle flow channel 19, the outer nozzle flow channel is provided with a 20, and screw There is an air-conditioning group 21; the paint inlet partition 30 is a hollow body, which is placed in the paint inlet 17 of the gun body of the gun body group 10, and one end thereof is pressed against the main air passage of the gun body of the gun body group 10. 15. Connect the paint flow channel and separate the paint inlet 17 of the gun body 10 and the main air passage 15 of the gun body, so that the air passage 15 of the gun body of the gun body 10 can pass through the paint inlet 17; The fixing element 40 of the paint inlet partition sleeve is provided with a hole at its pivot, and is screwed to the paint inlet 17 of the gun body of the gun body group, and fixes the paint inlet partition sleeve 30 tightly.

By the above components, as shown in the fourth figure, the depth of the inner nozzle shunt 18 and the outer nozzle shunt 19 are greatly reduced, which is easy to produce and process; the air conditioning group 20 is on the side of the gun head, and there is a larger Operating space.

To sum up, compared with conventional articles, this writing is superior to conventional articles in the following points:

1. The cross-sectional area of the air channel in the gun body can be better than that of conventional products, and a larger air flow can be obtained.

2. The runner is easy to process and improve the stability of production quality.

3. The operation space of the adjusting knob is enough, and it conforms to the ergonomic operation position.
