[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] A dustproof formaldehyde detection device for building coatings includes a cabinet 1, a cabinet door 2 hinged to the front of the cabinet 1, an electric push rod 3 installed on the top of the cabinet 1, a heating tank 4 slidably connected inside the cabinet 1, a lid 5 on the top of the heating tank 4, and a formaldehyde detector 14 on the top of the lid 5.

[0025] The side wall of the cabinet 1 is provided with a ventilation component for accelerating airflow. The ventilation component includes two fans 10 fixedly connected to the side wall of the cabinet 1. Several air inlets 6 are opened through the left side of the cabinet 1, and a filter plate 9 is slidably connected inside the air inlet 6. The filter plate 9 is located to the left of the fan 10. Several air outlets 7 are opened through the right side of the cabinet 1, and a filter screen 11 is fixedly connected inside the air outlet 7. The side wall of the cabinet 1 is provided with a locking device for fixing the filter plate 9.

[0026] The bottom of the bucket lid 5 is provided with a stirring assembly for mixing architectural coatings. The stirring assembly includes a motor 8 fixedly connected to the top of the bucket lid 5, and the top of the motor 8 is fixedly connected to the telescopic end of the electric push rod 3. The driving end of the motor 8 is fixedly connected to a stirring shaft 16, and a plurality of evenly distributed stirring blades 17 are fixedly connected to the outer wall of the stirring shaft 16. Two symmetrical connecting rods 18 are fixedly connected to the outer wall of the stirring shaft 16, and scrapers 19 are fixedly connected to the side walls of the connecting rods 18.

[0027] The locking component includes a sliding rod 20 that is slidably connected to the side wall of the cabinet 1, and a pull ring 21 is rotatably connected to one end of the sliding rod 20 that passes through the cabinet 1. A limit plate 23 is fixedly connected to the outer wall of the sliding rod 20, and a spring 22 is sleeved on the outer wall of the sliding rod 20. One end of the spring 22 is fixedly connected to the side wall of the limit plate 23.

[0028] The side wall of the cabinet 1 is provided with a sliding groove 24, and the side wall of the filter plate 9 is provided with a through hole 25 that communicates with the sliding groove 24.

[0029] The end of the spring 22 away from the limiting plate 23 is fixedly connected to the inner wall of the slide groove 24. When the filter plate 9 is in the locked state, one end of the sliding rod 20 is slidably inserted into the inside of the through hole 25.

[0030] Two symmetrical handles 12 are fixedly connected to the outer wall of the heating tank 4. Multiple evenly distributed guide blocks 13 are fixedly connected to the outer wall of the heating tank 4. Multiple guide grooves are opened on the inner bottom wall of the cabinet 1, and the outer wall of the guide block 13 is slidably inserted into the guide groove. A sealing ring 15 is fixedly connected to the inner wall of the tank cover 5.

[0031] Working Principle: In operation, the electric push rod 3 is first activated, causing the lid 5 to rise, releasing the volatile gases. Simultaneously, two fans 10 are activated, blowing outside air into the cabinet 1. The filter plate 9 purifies the outside air, preventing dust or dirt from entering the cabinet 1. Finally, the air is exhausted through several air outlets 7, carrying away the volatile gases and accelerating the dissipation process, thus facilitating the testing of the next type of architectural coating. Meanwhile, the filter screen 11 prevents external air from entering the cabinet when the two fans 10 are not activated. Dust and dirt enter the cabinet 1. After prolonged use, dust and dirt will accumulate on the surface of the filter plate 9, affecting the purification efficiency. By pulling the pull ring 21, the sliding rod 20 will slide outward, and the spring 22 will be released and restored through the limit plate 23, thereby releasing the fixation of the filter plate 9 for cleaning, ensuring the purification efficiency of the filter plate 9. Finally, the cleaned filter plate 9 is slid back, and the pull ring 21 is released, causing the spring 22 to be released and restored, driving the sliding rod 20 to be inserted into the through hole 25, thereby fixing the filter plate 9.

[0032] Secondly, when it is necessary to test the building coating, the electric push rod 3 is activated to move the bucket lid 5 down and form a seal with the heating bucket 4 through the sealing ring 15. At this time, the motor 8 is activated to drive the stirring shaft 16 and multiple stirring blades 17 to rotate, which can stir the coating in the heating bucket 4 and prevent the coating from curing. At the same time, the rotation of the stirring shaft 16, under the action of the two connecting rods 18, can drive the scraper 19 to rotate back and forth around the center point of the stirring shaft 16 and scrape off the coating adhering to the inner wall of the heating bucket 4, thereby achieving uniform stirring. Finally, the formaldehyde detector 14 is used to detect the volatile gas.

[0033] Finally, by activating the electric push rod 3, the lid 5 is moved upward, and the heating barrel 4 is moved out of the cabinet 1 by the two handles 12 on the outer wall of the heating barrel 4. The inside of the heating barrel 4 can be cleaned for reuse. At the same time, the two fans 10 are activated to accelerate the airflow in the cabinet 1, thereby speeding up the testing process. Finally, the heating barrel 4 is positioned by multiple guide blocks 13 and guide grooves.
