During epidemics, health codes of people entering and leaving must be verified and their temperatures taken to prevent the spread of the epidemic.

[0003] In the current security work, identity recognition, temperature measurement, and health code verification require the installation of many devices in different locations. The security inspection process is complicated and cumbersome, and it is easy to cause congestion at the security inspection entrance when there is a large flow of people. The existing security equipment is fixed in a certain position and cannot be adjusted according to the height of the person being measured or the detection position.

[0038] like Figure 6 and Figure 7 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the dust collecting assembly includes a dust box 10, the top ends of both sides of the dust box 10 are symmetrically fixedly connected with sliders 11, the bottom of the air intake frame 4 is symmetrically fixedly connected with slide rails 9, the sliders 11 are slidably connected to the inner walls of the slide rails 9, a dust exhaust groove is provided at the bottom of the air intake frame 4, a guide plate 12 is fixedly connected between the inner walls of the dust exhaust groove, and a leakage hole 13 is provided on the guide plate 12.

[0039] In this embodiment, the dust box 10 can be quickly assembled and disassembled by sliding the slider 11 along the slide rail 9 .

[0040] Example 3

[0041] like Figure 5 and Figure 7 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, the positioning assembly includes a connecting plate 14, the connecting plate 14 is fixedly connected between the filter screen 8 and the dust box 10, the inner side of the air intake frame 4 is fixedly connected with a fixing plate 15, one side of the fixing plate 15 is slidably connected with a slide rod 16, one end of the slide rod 16 is fixedly connected with a rivet bolt 19, the end of the slide rod 16 away from the rivet bolt 19 is fixedly connected with a pad 17, the outer side of the slide rod 16 and located between the pad 17 and the fixing plate 15 is provided with a spring 18, one side of the connecting plate 14 is provided with a cross-shaped horizontal groove 21 and a vertical groove 20, and the vertical groove 20 is configured as a through groove.

[0042] In this embodiment, when the dust box 10 and the filter 8 need to be disassembled, the rivet bolt 19 is pulled and rotated until the rivet bolt 19 is opposite to and fits into the vertical groove 20. At this time, the connecting plate 14 can be taken out, and then the filter 8 and the dust box 10 are both taken out and can be cleaned; when installing, the filter 8 is slid in along the slide groove 7. During this process, the slider 11 slides to the bottom along the slide rail 9. At this time, the connecting plate 14 contacts the fixed plate 15, and the rivet bolt 19 passes through the vertical groove 20. The rivet bolt 19 can be pulled and rotated to fit with the transverse groove 21. The rivet bolt 19 is released and inserted into the transverse groove 21 to complete the fixation of the connecting plate 14.

[0045] Preferably, the leakage hole 13 is configured as an inverted truncated cone structure.

[0046] In this embodiment, the leakage hole 13 is set to an inverted truncated cone structure, and dust is relatively easier to move from top to bottom, but more difficult to move from bottom to top. Its working principle is similar to that of a funnel, so that dust can more easily enter the dust box 10 and is more difficult to be lifted from the dust box 10.

[0047] like Figure 5 and Figure 7 As shown, preferably, notches are symmetrically provided on both sides of the riveting bolt 19 .

[0048] In this embodiment, a large groove is provided at the connection between the transverse groove 21 and the vertical groove 20 so that the operator can operate the riveting bolt 19 with the thumb.

[0050] In this embodiment, the connection between the dust box 10 and the air intake frame 4 has a certain degree of sealing to prevent air from passing through the gap between the two from the outside and forming an air flow channel with the inside of the charging cabinet body 1, thereby preventing dust from being raised again.

[0051] The working principle of the circuit component inflatable cabinet with protective function is described in detail below.

[0052] like Figure 1-7As shown, when the inside of the inflatable cabinet body 1 needs to dissipate heat, the cooling fan 5 is controlled to work and blow air outward, so that the heat in the inflatable cabinet body 1 is discharged along with the exhaust fan. On the other side of the inflatable cabinet body 1, air enters from the air inlet 3 and is blocked by the partition 6. It will first flow downward and pass through the filter screen 8 after a large turn to enter the inside of the inflatable cabinet body 1. In this process, the air will move downward and carry dust downward. Since the position below the air inlet 3 in the air inlet frame 4 is not connected to the outside, an air flow path cannot be formed, and the dust that moves to this area is not easily The dust is sucked into the gas cabinet body 1. Even if some dust has a tendency to enter the gas cabinet body 1 due to the influence of the airflow, it cannot enter the gas cabinet body 1 due to the obstruction of the filter 8, so as to achieve dust protection; the dust that is not sucked in falls on the partition 6 under the action of gravity, and passes through the leakage hole 13 with gravity and enters the dust box 10, wherein the leakage hole 13 is set to an inverted frustum-shaped structure, and the dust is relatively easier to move from top to bottom, and more difficult to move from bottom to top. Its working principle is similar to that of a funnel, so that the dust can enter the dust box 10 more easily and is more difficult to be lifted from the dust box 10. When it is necessary to clean the dust, the rivet bolt 19 is pulled and rotated until the rivet bolt 19 is opposite to and fits into the vertical groove 20. At this time, the connecting plate 14 can be taken out, so that the filter screen 8 and the dust box 10 are both taken out and can be cleaned; during installation, the filter screen 8 is slid in along the slide groove 7. During this process, the slider 11 slides to the bottom along the slide rail 9. At this time, the connecting plate 14 contacts the fixing plate 15 and the rivet bolt 19 passes through the vertical groove 20. The rivet bolt 19 can be pulled and rotated to fit with the transverse groove 21. The rivet bolt 19 is released and inserted into the transverse groove 21 to complete the fixation of the connecting plate 14, thereby realizing the rapid installation of the dust box 10 and the filter screen 8, which greatly facilitates practical applications.

[0053] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
