[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5A formaldehyde detection sampling device includes a sampler body 1 and a bracket 2. The sampler body 1 is connected to the bracket 2 by screws 3. Multiple groups of anti-skid pads 4 are fixedly connected to the upper end of the bracket 2. The ground of the sampler body 1 contacts the end faces of the multiple groups of anti-skid pads 4. Multiple groups of suction cups 8 are fixedly connected to the outer wall of the bracket 2. An air cavity 6 is opened in the bracket 2. The air cavity 6 is connected to the inside of the multiple groups of suction cups 8. A piston 7 is slidably connected in the air cavity 6. A driving component for driving the piston 7 to slide is installed on the outer wall of the bracket 2. Compared with the traditional installation method that requires drilling holes, the device can fix the bracket 2 by the suction cup 8, thereby avoiding physical damage to furniture, walls or ceilings. This not only protects the beauty of the interior, but also reduces destructive operations during installation.

[0023] The driving assembly includes a connecting rod 11 fixedly connected to the outer wall of the piston 7, a slide groove 5 is opened on the outer wall of the bracket 2, the slide groove 5 is communicated with the inside of the air cavity 6, a slide rod 10 is slidably connected in the slide groove 5, and the end of the connecting rod 11 is fixedly connected to the outer wall of the slide rod 10. A closed space is formed by the contact between the suction cup 8 and the wall. With the help of the sliding of the piston 7, the air in the suction cup 8 can be sucked into the air cavity 6. The external atmospheric pressure forces the suction cup 8 to be more firmly adsorbed on the wall, thereby significantly enhancing the adsorption force.

[0024] The outer wall of the bracket 2 is fixedly connected to a side plate 12, and the outer wall of the side plate 12 is slidably connected to a pin 13, one end of the pin 13 passes through the interior of the slide rod 10, and the end of the pin 13 is fixedly connected to a slider 14, and the radius of the slider 14 is larger than the radius of the pin 13. A spring 9 is sleeved on the outer wall of the pin 13, one end of the spring 9 is fixedly connected to the slider 14, and the other end of the spring 9 is fixedly connected to the side plate 12. The outer wall of the slider 14 is provided with multiple groups of anti-skid grooves, and the multiple groups of anti-skid grooves are annularly distributed on the outer wall of the slider 14; with the help of the setting of the pin 13, the position of the piston 7 can be stably limited, and the setting of the spring 9 can ensure the stability of the pin 13 inserted into the outer wall of the slide rod 10.

[0025] In the utility model, when the device is used specifically: the side of the bracket 2 with the suction cup 8 is brought close to the wall, ceiling or furniture surface to be fixed, ensuring that the suction cup 8 is in full contact with the surface to form a closed space, and the sliding rod 10 is slid to make the piston 7 slide in the air cavity 6. During the sliding process, the piston 7 draws the air in the suction cup 8 into the air cavity 6 to form a partial vacuum state. As the internal air pressure decreases, the external atmospheric pressure forces the suction cup 8 to be more firmly adsorbed on the wall or other surfaces, which significantly enhances the fixing effect of the bracket 2 and ensures that the device is firmly installed in the designated position.

[0026] When the device reaches the appropriate position, the pin 13 on the side plate 12 slides into place and inserts into the outer wall of the slide rod 10 to ensure that the position of the piston 7 does not move accidentally. The elastic force of the spring 9 ensures that the pin 13 always remains in the correct position, providing additional fixation and stability.

[0027] After the device is firmly installed, formaldehyde detection begins. The sampler body 1 will collect and analyze the formaldehyde content in the indoor air, and collect and record the air data at a specified height according to the built-in sensors and detection equipment of the device to ensure the accuracy and multi-point coverage of the data. After the detection work is completed, the piston 7 slides in the opposite direction by sliding the slide rod 10, gradually releasing the vacuum state inside the suction cup 8 and releasing the firm adsorption of the suction cup 8 to the surface.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
