[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Reference Figures 1-6A positive-pressure environmentally friendly spray painting booth includes a booth body 1 and a door 2. The door 2 is hinged to the front of the booth body 1. The booth body 1 provides fixing points for the door 2, electric heating tube 5, air inlet shell 6, connecting hole 10, output shell 11, and electric telescopic rod 15, which are fixedly connected to its outer surface. The door 2 is hinged to the front of the booth body 1, providing space for the user to open the booth body 1 by external force, and also providing a force point for the viewing window 3 and pull handle 4, which are fixedly connected to its outer surface. The viewing window 3 is embedded in the front of the door 2, providing space for the user to view the interior of the booth body 1. The pull handle 4 is fixedly connected to the front of the door 2. The front of the door 2 provides a point of leverage for the user to open the door 2 with external force, and also provides a point of leverage for the user to close the chamber 1. The handle 4 is located inside the viewing window 3. An electric heating tube 5 is fixedly connected inside the chamber 1. When it is necessary to dry the paint, electrical energy can be transmitted to the inside of the electric heating tube 5 through an external control component. At this time, the resistance wire inside the electric heating tube 5 continuously transmits heat to the outer surface of the metal parts through the electrothermal effect to bake the paint. There are two electric heating tubes 5. An air inlet shell 6 is connected through the top of the chamber 1. The air inlet shell 6 is connected through the top of the chamber 1 and is fixedly connected to the first filter layer 7, the second filter layer 8, and the drum on its outer and inner surfaces. A fan 9 provides a fixed point. A first filter layer 7 is fixedly connected to the inner side of the air intake shell 6. When air is delivered into the air intake shell 6, the first filter layer 7 intercepts fine and large dust particles in the air. A second filter layer 8 is fixedly connected to the inner side of the air intake shell 6. The second filter layer 8 is fixedly connected below the first filter layer 7 and is made of multiple layers of filter cloth. It performs secondary filtration on the air after the initial filtration, thereby improving the user experience of the chamber 1. The second filter layer 8 is located below the first filter layer 7. A blower 9 is fixedly connected to the top of the air intake shell 6. When it is necessary to raise the chamber 1... When the airflow velocity of body 1 is such that an external control component can transmit electrical energy to the interior of blower 9, blower 9 generates suction force on the air in the external environment and delivers the air to the interior of air intake shell 6. A connecting hole 10 is provided through the top of body 1, providing space for external pipes to extend into the interior of body 1 and spray paint onto the outer surface of external metal products. Output shells 11 are connected through both sides of body 1, providing fixing points for the first intercepting layer 12, the second intercepting layer 13 and the third intercepting layer 14 fixedly connected inside them. The connecting hole 10 is located in front of air intake shell 6.

[0022] Reference Figure 1 and Figure 7The inner side of the output housing 11 is fixedly connected to a first interception layer 12, which is made of metal woven mesh and intercepts large particulate pollutants inside the chamber 1. The inner side of the output housing 11 is fixedly connected to a second interception layer 13, which is made of multiple layers of filter cloth. When exhaust gas enters the interior of the second interception layer 13, the second interception layer 13 intercepts fine pollutants in the air. The second interception layer 13 is located outside the first interception layer 12. The inner side of the output housing 11 is fixedly connected to a third interception layer 14, which is made of filter cloth wrapped with activated carbon. When exhaust gas inside the chamber 1 is transported to the interior of the third interception layer 14, the third interception layer 14 adsorbs fine pollutants in the air, thereby completing the exhaust gas treatment. The third interception layer 14 is located outside the second interception layer 13.

[0023] Reference Figures 4-5 An electric telescopic rod 15 is fixedly connected inside the chamber 1. When the painting height of the metal product needs to be adjusted, electrical energy can be transmitted to the electric telescopic rod 15 via an external control component. At this time, the electric telescopic rod 15 extends or retracts to adjust the height of the metal product, thereby improving the painting effect. Four electric telescopic rods 15 are provided, and a support frame 16 is fixedly connected to the tail end of each rod. The support frame 16 is fixedly connected to the tail end of the electric telescopic rod 15, providing a fixing point for the shielding shell 17 fixedly connected to its top. The shielding shell 17 is fixedly connected to the top of the support frame 16. The shield 17 is fixedly connected to the top of the support frame 16, providing a fixing point for the geared motor 18 fixedly connected inside. The geared motor 18 is fixedly connected inside the shield 17. When it is necessary to drive the metal product to rotate, electrical energy can be transmitted to the inside of the geared motor 18 through an external control component. At this time, the geared motor 18 transmits rotational power to the inside of the geared motor 18 through electromagnetic effect, and the output end of the geared motor 18 extends to the outside of the shield 17. The output end of the geared motor 18 is fixedly connected to the support plate 19, which provides support for the metal product. Under the drive of the geared motor 18, the metal product rotates, which facilitates the subsequent painting work.

[0024] In use, the metal product is moved to the top of the support plate 19, and then the paint spray head is inserted into the connecting hole 10 by external force. After that, the box door 2 is closed and the external fixing plate is inserted into the pull handle 4 to fix the box door 2. Then, the paint is sprayed onto the outer surface of the metal product by the external control component, and the electrical energy is transmitted to the inside of the electric telescopic rod 15. At this time, the electric telescopic rod 15 extends, driving the metal product at its output end to move upward. The reduction motor 18 transmits the rotational power to the inside of the support plate 19 through electromagnetic effect to further adjust the position of the metal product. After the metal product is painted, the electrical energy is transmitted to the inside of the blower 9 and the electric heating tube 5 by the external control component to increase the temperature inside the chamber 1 and increase the air flow rate inside the chamber 1, thereby completing the paint drying inside the chamber 1. After that, the painted metal product is taken out.
