[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Reference Figures 1-3A cleanroom body for an automotive spray painting booth includes: a painting chamber 1, with fixed plates 3 fixedly installed on both inner walls of the painting chamber 1, fixed grooves 5 on the fixed plates 3, and a lead screw slider 7 slidably connected between the inner walls of the fixed grooves 5, and a fixed scraper 8 fixedly connected between the lead screw slider 7, with the bottom end of the fixed scraper 8 abutting against the inner wall of the painting chamber 1; a motor 4 fixedly connected to the side wall of one side of the fixed plate 3, and a reciprocating lead screw 6 fixedly connected to the output end of the motor 4, the reciprocating lead screw 6 passing through the corresponding fixed plate 3 and the lead screw slider 7, and the reciprocating lead screw 6 mechanically matching the corresponding lead screw slider 7; a spraying device is installed inside the painting chamber 1, and the spraying device, motor 4 and controller are publicly available technologies, so they are not described in detail here;

[0019] Start motor 4. The output end of motor 4 drives the reciprocating lead screw 6 to rotate. Since the lead screw slider 7 cannot rotate, the rotation of the reciprocating lead screw 6 will drive the lead screw slider 7 to move back and forth, causing the fixed scraper 8 to move back and forth as well, scraping off the falling paint and pushing it to the connecting pipe 9, so that the paint baking chamber 1 is kept clean.

[0020] A drainage structure is installed on the paint baking chamber 1. The drainage structure includes a connecting pipe 9 fixedly connected to the rear end of the paint baking chamber 1. A through groove 10 is opened between the connecting pipe 9 and the paint baking chamber 1 to connect the two. A connecting shaft 11 is connected between the inner walls of the connecting pipe 9. Multiple sets of fan blades 12 are fixedly connected to the side wall of the connecting shaft 11. One end of the connecting shaft 11 passes through the inner wall of the corresponding connecting pipe 9 and is fixedly connected to a second bevel gear 16. A reciprocating screw 6 passes through the paint baking chamber 1 and is fixedly connected to a first bevel gear 15. The first bevel gear 15 meshes with the second bevel gear 16.

[0021] When the reciprocating screw 6 rotates, the first bevel gear 15, which is fixedly connected to it, moves accordingly, causing the second bevel gear 16, which meshes with the first bevel gear 15, to rotate together. This causes the connecting shaft 11, which is fixedly connected to the second bevel gear 16, to rotate, and the fan blade 12, which is fixedly mounted on the connecting shaft 11, to rotate as well, thereby allowing air to flow and drawing the air in the paint baking chamber 1 into the connecting pipe 9 for discharge.

[0022] A protective shell 14 is fixedly installed on the side wall of the paint baking chamber 1. The protective shell 14 is fixedly connected to the connecting pipe 9, and the protective shell 14 encloses the first bevel gear 15 and the second bevel gear 16 inside. An installation pipe 13 communicating with the inside of the connecting pipe 9 is fixedly installed at the top of the connecting pipe 9. The installation pipe 13 has a ventilation effect, allowing air to enter from the installation pipe 13 and causing air flow. This draws the paint in the air in the paint baking chamber 1 towards the connecting pipe 9. At the same time, the installation pipe 13 is connected to a water pump, and water is passed through the installation pipe 13 to clean the connecting pipe 9. The inner wall of the connecting groove 10 has a chamfer, which is inclined towards the connecting pipe 9. The chamfer helps to scrape the falling paint into the connecting pipe 9.

[0023] The inner wall of the paint baking chamber 1 is fixedly installed with a moving guide rail. The paint baking chamber 1 is slidably installed with a sliding door 2 via the moving guide rail. The sliding door 2 is fixedly installed with a door handle and is made of transparent material, so that the condition inside the paint baking chamber 1 can be seen through the sliding door 2, so as to facilitate the control of the paint baking device. The outer side of the paint baking chamber 1 is equipped with a controller corresponding to the motor 4 and the paint spraying device. The controller can control the motor 4 and the paint spraying device.

[0024] In use, this invention involves painting a car using a paint baking device. Simultaneously, the starter motor 4 is activated, and its output drives the reciprocating lead screw 6 to rotate. Since the lead screw slider 7 cannot rotate, the rotation of the reciprocating lead screw 6 causes the slider 7 to move back and forth, resulting in the fixed scraper 8 moving back and forth to scrape off the falling paint and push it to the connecting pipe 9. Furthermore, as the reciprocating lead screw 6 rotates, the first bevel gear 15, which is fixedly connected to it, moves accordingly, driving the second bevel gear 16, which meshes with the first bevel gear 15, to rotate. This causes the connecting shaft 11, which is fixedly connected to the second bevel gear 16, to rotate, causing the fan blades 12, which are fixedly mounted on the connecting shaft 11, to rotate as well. This creates airflow, drawing air from the paint baking chamber 1 into the connecting pipe 9 and expelling it, completely cleaning the air and the falling paint. The entire paint baking chamber 1 remains clean. Additionally, the mounting pipe 13 is connected to a water pump, allowing water to flow through it and clean the connecting pipe 9.
