Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-6 This utility model provides a technical solution for an air suspension spray gun: an air suspension spray gun includes a base 1, an aluminum cover 5 installed on the upper end of the base 1, a connecting flange 51 provided on the inner side of the aluminum cover 5, a paint supply pipe 3 passing through the middle of the base 1 and the aluminum cover 5, an oil pipe head 31 installed at the top of the paint supply pipe 3, the base 1 and the forming cover 2 are threadedly connected, the oil pipe head 31 and the top of the paint supply pipe 3 are threadedly connected, the base 1 and the aluminum cover 5 are also provided with exhaust holes 11, and the exhaust holes 11 on the base 1 and the aluminum cover 5 are interconnected to form an exhaust channel, the paint enters through the oil inlet at the bottom of the paint supply pipe 3, that is, the paint supply pipe 3 at the base 1, and is atomized and sprayed out by the cooperation of the oil pipe head 31 and the part cup 4;

[0026] like Figure 3 and 5 As shown, a motor rotating spindle 7 is installed on the outside of the paint delivery pipe 3. A rotating disk is installed on the lower outer side of the motor rotating spindle 7, and the outer wall of the rotating disk has multiple rotating air teeth 71 arranged in a circumferential array. The rotating disk is placed inside the aluminum cover 5. A spacer ring 52 is installed on the inner side of the aluminum cover 5 corresponding to the rotating disk. The spacer ring 52 is fixed to the aluminum cover 5 through a connecting flange 51. The rotating air teeth 71 of the motor rotating spindle 7 adopt a return air design, which facilitates greater rotation force during use and allows for high-speed rotation even when the paint volume is large or the load is heavy. Compared with the disadvantages of traditional motor spindles such as low life, easy wear, poor precision and low speed, the spindle of this design is equipped with rotating air teeth 71, which not only has low wear but also high precision, high speed and temperature, and high speed, so as to better centrifuge the paint, reduce paint waste and improve the adsorption effect of the paint after atomization.

[0027] like Figure 3As shown, a copper sleeve 61 is fitted on the outer side of the motor rotating spindle 7 above the rotating disk. An aluminum sleeve 6 is fitted on the outer side of the copper sleeve 61. An atomizing cap 8 is set at the top of the aluminum sleeve 6. A part cup 4 is installed on the inner side of the atomizing cap 8 corresponding to the oil pipe head 31. A forming cover 2 is installed on the outer side of the upper end of the base 1. The forming cover 2 covers the aluminum cover 5, the aluminum sleeve 6 and the atomizing cap 8, which can play a sealing and protective role. A sealing ring 9 is also provided between the outer side of the upper end of the atomizing cap 8 and the forming cover 2. An air inlet hole 12 is opened on the base 1, the aluminum cover 5 and the aluminum sleeve 6. The air inlet holes 12 on the base 1, the aluminum cover 5 and the aluminum sleeve 6 are interconnected and form an air supply channel. An air distribution hole 13 is also provided on the aluminum sleeve 6. The air distribution hole 13 is connected to the air supply channel. The air supply channel is connected to the forming cavity of the atomizing cap 8 through the air distribution hole 13.

[0028] like Figure 6 As shown, the upper part of the copper sleeve 61 has four sets of static air float holes 611 evenly spaced from bottom to top. Each set of static air float holes 611 has twelve holes and they are arranged in a ring on the copper sleeve 61. The bottom outer side of the copper sleeve 61 has six axial air float holes 612 arranged in a circle. The copper sleeve 61 has 48 static air float holes 611 and 6 axial air float holes 612. This design ensures the stability of air float during use, thereby ensuring the stability of the high-speed rotation of the motor spindle 7, so as to ensure the paint atomization effect.

[0029] The working principle of this utility model is as follows: When in use, the paint enters the paint supply pipe 3 through the inlet of the paint supply pipe 3 on the bottom surface of the base 1. After the high-speed rotation of the motor rotating main shaft 7, the gas is formed into a high-pressure airflow. The high-pressure gas flow will cause the paint to break into fine mist particles, which are then sprayed out in an atomized form, making it convenient to coat the product.

[0030] This design uses air suspension drive, with gas delivered through the air supply channel. The gas is used to make the motor rotate the main shaft 7 at high speed. The air suspension spray gun uses high-speed airflow to generate high pressure at the nozzle part of the spray gun (i.e., at the part cup 4). The high-pressure airflow causes the paint liquid at the oil pipe head 31 to break into fine mist particles. With the help of the gas flow, the mist particles are sprayed onto the surface of the target object.

[0031] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
