[0022] 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.

[0023] Please see Figure 1 , 2 As shown in Figures 3, 4, and 5, this utility model provides a technical solution: an indoor environment detection device, comprising: a storage box 1; a support mechanism located at the bottom of the storage box 1, the support mechanism including a support slide rod 2 vertically slidably connected to the bottom of the storage box 1, a support base plate 3 fixedly connected to the bottom of the support slide rod 2, and a limiting part for fixing the position of the support slide rod 2 installed on the outside of the storage box 1; and a lifting mechanism located inside the storage box 1, the lifting mechanism including a scissor lift 11 installed inside the storage box 1 and a drive scissor lift. The electric push rod 14 is raised and lowered. One end of the electric push rod 14 is rotatably installed inside the storage box 1. The storage box 1 contains a battery that is electrically connected to the electric push rod 14. A corresponding control switch is installed on the outside of the storage box 1. A lifting plate 9 is installed on the top of the scissor lift 11. The detection and collection unit is located on the top of the lifting plate 9. The detection and collection unit includes an air sampler 10 and a formaldehyde detector 7. The air sampler 10 is a QC-1S model, and the formaldehyde detector 7 is a Silezhi MEF-550 model.

[0024] It should be noted that in this embodiment, the storage box 1 is placed in the room where measurement and sampling are required. By stepping on both sides of the supporting base plate 3, the storage box 1 is lifted upwards, thereby pulling the crossbar 4 upwards along the supporting slide bar 2. Under the action of the limiting part, the supporting slide bar 2 is restricted to a designated position. Then, the electric push rod 14 is controlled by the corresponding control switch to drive the scissor lift 11 to rise, thereby pushing the air sampler 10 and the formaldehyde detector 7 out of the storage box 1. The air sampler 10 samples the indoor air, which is convenient for analyzing and testing the indoor air in the laboratory. The formaldehyde detector 7 detects formaldehyde and other substances in the indoor air.

[0025] In one embodiment, the storage box 1 has an elastic slot 8 fixedly connected to its side, a support rod 20 installed inside the elastic slot 8, a box cover 6 hinged to the top of the storage box 1, a hook installed on one side of the storage box 1, a protrusion for the hook to engage, and a connecting tube for engaging with the support rod 20 on the top of the box cover 6.

[0026] It should be noted that in this embodiment, the elastic groove 8 is a plastic ring with a notch. The support rod 20 is inserted into the elastic groove 8. The top of the support rod 20 is provided with a threaded post and the bottom is provided with a threaded hole that mates with the threaded post. After the support rod 20 is spliced, it is inserted into the connecting tube of the box cover 6. The box cover 6 is flipped over, and the bottom of the support rod 20 contacts the ground. At this time, the box cover 6 is in a horizontal state, which can increase the stability of the storage box 1. The sampled reagent bottle is placed in the supported box cover 6.

[0027] In one embodiment, a crossbar 4 is fixedly connected to the top of the support slide bar 2, and a spring 5 is sleeved on the outside of the support slide bar 2 and at the bottom of the crossbar 4. The limiting part includes a fixing box 15 fixed to the outside of the storage box 1. A limiting pin 16 for limiting the crossbar 4 is slidably connected inside the fixing box 15. A baffle 17 is fixedly connected to the outside of the limiting pin 16. The baffle 17 is slidably connected to the fixing box 15. A spring 18 is sleeved on the outside of the limiting pin 16 and between the fixing box 15 and the baffle 17.

[0028] It should be noted that in this embodiment, by stepping on both sides of the support base plate 3, the storage box 1 is lifted upwards. The crossbar 4 compresses the spring 5 on the outside of the support slide bar 2. The support base plate 3 drives the crossbar 4 to press the limiting pin 16 downwards through the support slide bar 2. Because the end of the limiting pin 16 is a beveled structure, under the compression of the crossbar 4, the limiting pin 16 is pushed into the fixed box 15, thereby causing the crossbar 4 and the limiting pin 16 to be misaligned. Under the push of the spring 18, the baffle 17 drives the limiting pin 16 to reset, thereby limiting the crossbar 4 at the bottom of the limiting pin 16, thus limiting the position of the crossbar 4. This allows the support base plate 3 to support the storage box 1 through the support slide bar 2. When unlocking, the limiting pin 16 is pulled, causing the end of the limiting pin 16 to retract into the fixed box 15. Under the reset action of the spring 5, the crossbar 4 drives the support base plate 3 to reset at the bottom of the storage box 1 through the support slide bar 2.

[0029] In one embodiment, one end of the bottom of the scissor lift 11 is rotatably connected to the storage box 1, and the other end of the bottom of the storage box 1 is rotatably connected to a moving wheel 13. A limiting groove 12 is fixed inside the storage box 1, and the moving wheel 13 slides inside the limiting groove 12. A metal rod is rotatably connected to the lowermost intersection of the scissor lift 11, and the output end of the electric push rod 14 is rotatably connected to the metal rod. The limiting groove 12 has a U-shaped structure, and a groove is opened in the middle of the limiting groove 12. A support shaft is installed in the middle of the moving wheel 13, and the support shaft is slidably connected to the groove. One end of the top of the scissor lift 11 is rotatably connected to the bottom of the lifting plate 9, and the other end of the top of the scissor lift 11 is slidably connected to the lifting plate 9.

[0030] It should be noted that, in this embodiment, when the lifting plate 9 is raised, the electric push rod 14 pushes the metal rod at the lowest intersection of the scissor lift 11, thereby pushing one end of the bottom of the scissor lift 11 to drive the moving wheel 13 to slide inside the limiting slide groove 12, and the top end of the scissor lift 11 slides at the bottom of the lifting plate 9. In this way, the lifting plate 9 is lifted upward by the scissor lift 11, so that the air sampler 10 and the formaldehyde detector 7 are raised to the specified height. Therefore, there is no need to disassemble and install the tripod each time. When the scissor lift 11 is lowered, the equipment on the top of the lifting plate 9 is directly stored in the storage box 1. The equipment can be carried and transported through the storage box 1 without the need to carry additional auxiliary support tools such as tripods.
