[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses an air quality monitor. Figure 1An air quality monitor includes a monitor body 1 and a casing 2. The monitor body 1 is located inside the casing 2. The side wall of the casing 2 is rotatably connected with a support leg 3. A finger sleeve 7 is installed on the side wall of the support leg 3 away from the casing 2. A cavity is also provided inside the finger sleeve 7. The setting of the finger sleeve 7 makes it easier for a worker to hold the monitor body 1, so that the monitor body 1 has two monitoring modes.

[0020] Reference Figure 2 A vertical groove 4 is provided on the side wall of the supporting leg 3 close to the casing 2, and a storage groove 5 which is in the same shape as the supporting leg 3 is provided on the side wall of the casing 2. A placement groove 8 is provided in the storage groove 5. The shape of the placement groove 8 is in the same shape as the support rod 6, and the length of the placement groove 8 is also in the same length as the support rod 6. When the monitor body 1 is converted into a handheld form, the support rod 6 can be received in the placement groove 8, so that the supporting leg 3 can fit in the storage groove 5, making the handheld state more convenient;

[0021] A support rod 6 is rotatably connected in the storage groove 5, and the other end of the support rod 6 is slidably connected to the side wall of the vertical groove 4. The limiting plate 12 is designed to be arc-shaped at one end away from the support rod 6. When the support rod 6 slides from top to bottom, the arc-shaped limiting plate 12 is more convenient for the support rod 6 to pass through, while the other end is not arc-shaped, which can prevent the support rod 6 from moving;

[0022] Reference Figure 3 A cavity is provided in the supporting leg 3, and a limiting mechanism is installed in the cavity. The limiting mechanism includes a connecting rod 9, a vertical rod 10, a moving plate 11, a limiting plate 12, two springs 15 and two paddles 13. The two paddles 13 are respectively located inside the finger sleeve 7. The connecting rod 9 is installed between the two paddles 13. A moving groove 14 is provided on the side wall of the finger sleeve 7. The connecting rod 9 is located in the connecting groove, and the connecting groove is connected to the cavity. The vertical rod 10 is installed at the bottom of the connecting rod 9, and the other end of the vertical rod 10 is fixedly connected to the side wall of the moving plate 11. Two springs 15 are respectively installed on the side walls of the moving plate 11, and a fixing plate 16 is installed on the side wall of the cavity. The other ends of the springs 15 are fixedly connected to the side walls of the fixing plate 16. The limiting plate 12 is installed on the side wall of the moving plate 11 away from the vertical rod 10. One end of the limiting plate 12 extends out of the side wall of the supporting leg 3. The side wall of the limiting plate 12 is against the side wall of the support rod 6. By pushing the paddle 13 upward, the limiting plate 12 can be retracted into the air, so that the support rod 6 can move upward, and the supporting leg 3 can be retracted into the receiving groove 5.

[0023] The implementation principle of an air quality monitor in an embodiment of the present application is as follows: when the monitor body 1 is to be placed in a certain position for a long time, the support leg 3 can be pulled out of the storage slot 5, so that the support leg 3 rotates, and the support rod 6 will move downward along the vertical slot 4. Since the upper end of the limiting plate 12 is arc-shaped, the support rod 6 will squeeze the limiting plate 12, thereby passing through the position of the limiting plate 12. When the support rod 6 moves to the bottom of the vertical slot 4, the limiting plate 12 will pop up under the action of the spring 15, thereby jamming the support rod 6 and preventing the support rod 6 from moving upward again. At this time, the shell 2, the support rod 6 and the support leg 3 will form a triangle, so that they are stably placed in the specified position. When the monitor body 1 is to be retracted, the paddle 13 can be pushed, so that the connecting rod 9 drives the vertical rod 10 to move upward, and then the vertical rod 10 drives the moving rod to move upward, so that the limiting plate 12 leaves the vertical slot 4 and retracts into the cavity. At this time, the support rod 6 loses its restriction and can slide up along the vertical slot 4, so that the support leg 3 is retracted into the storage slot 5.
