AI Technical Summary
Existing portable indoor environmental monitoring devices are prone to being dropped when manually handled, resulting in damage to the internal control board, and lack of a buffer structure for protection.
The device incorporates protective plates, damping springs, and buffer pads. The elastic deformation of the damping springs and the expansion and contraction of the dampers absorb impact energy, and the buffer columns further cushion the impact, protecting the internal components.
This effectively reduces the impact of drops on the internal control board and sensors, improving the durability and reliability of the equipment.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of indoor environmental testing technology, specifically a portable indoor environmental testing device. Background Technology
[0002] Portable indoor environmental monitoring devices can detect the components in the air through internal sensors that use resistive elements and photoelectric effects. By quantifying environmental data, they can help users scientifically improve indoor air quality.
[0003] During the design process of this utility model, the following problems were discovered in the existing technology:
[0004] When using existing equipment manually, it is inevitable that the equipment will slip from your hand and fall to the ground. Since most of the equipment does not have a cushioning structure, the internal control board will be damaged by the impact. Utility Model Content
[0005] The purpose of this invention is to provide a portable indoor environment detection device to solve the problem mentioned in the background art of the lack of a buffer structure inside the device.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a portable indoor environment detection device, comprising a housing, a protective plate installed at the bottom of the housing, a collection port provided on one side of the protective plate, a display panel installed at the top of the housing, a protective film installed at the top of the display panel, a damping spring installed at the bottom of the display panel, a buffer pad installed at the bottom of the damping spring, and a buffer column installed inside the buffer pad.
[0007] More preferably, an anti-slip pad is installed at one end of the outer shell of the machine body, and the anti-slip pads are symmetrically installed about the transverse center line of the outer shell of the machine body.
[0008] More preferably, the bottom of the buffer pad is provided with a control board, the upper end of the control board is equipped with a processor, and a sensor is provided on one side of the processor.
[0009] More preferably, one side of the sensor is provided with a wire, and the control board is connected to the display panel via the wire.
[0010] More preferably, a protective pad is installed on one side of the outer casing, and the protective pads are symmetrically installed about the transverse centerline of the outer casing.
[0011] More preferably, the buffer columns are evenly arranged along the inner wall of the buffer pad.
[0012] More preferably, the damping springs are evenly arranged along the inner wall of the protective plate, and the protective plate forms a telescopic structure through the damping springs.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] By adding a protective plate and damping springs, when the equipment is dropped and the protective plate is impacted, the damping spring at the bottom of the protective plate expands and contracts. The spring first undergoes elastic deformation, absorbing most of the impact energy. At the same time, the internal damper expands and contracts, converting the impact energy into heat energy. The spring and damper work together to reduce the impact on the control board inside the equipment. Meanwhile, the buffer column in the buffer pad at the bottom of the damping spring expands and contracts to buffer the remaining impact. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a portable indoor environment detection device, including a housing 1, a protective plate 13 installed at the bottom of the housing 1, a collection port 14 provided on one side of the protective pad 12, a display panel 3 installed at the top of the housing 1, a protective film 4 installed at the top of the display panel 3, a damping spring 5 installed at the bottom of the display panel 3, a buffer pad 6 installed at the bottom of the damping spring 5, and a buffer column 7 installed inside the buffer pad 6.
[0022] In this embodiment, as Figure 1 As shown, an anti-slip pad 2 is installed at one end of the outer shell 1, and the anti-slip pads 2 are symmetrically installed about the transverse center line of the outer shell 1.
[0023] In this embodiment, as Figure 2 and Figure 3 As shown, a control board 8 is provided at the bottom of the buffer pad 6, a processor 9 is installed at the top of the control board 8, and a sensor 10 is provided on one side of the processor 9.
[0024] In this embodiment, as Figure 2 and Figure 3 As shown, a wire 11 is provided on one side of the sensor 10, and the control board 8 is connected to the display panel 3 through the wire 11.
[0025] In this embodiment, as Figure 1 and Figure 4 As shown, a protective pad 12 is installed on one side of the outer shell 1, and the protective pads 12 are symmetrically installed about the transverse center line of the outer shell 1.
[0026] In this embodiment, as Figure 2 and Figure 3 As shown, the buffer pillars 7 are evenly arranged along the inner wall of the buffer pad 6.
[0027] In this embodiment, as Figure 2 and Figure 3 As shown, the damping springs 5 are evenly arranged along the inner wall of the protective plate 13, and the protective plate 13 forms a telescopic structure through the damping springs 5.
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the portable indoor environment monitoring device operates as follows during use:
[0029] First, when using the device, the user holds the outer casing 1. The anti-slip pads 2 on both sides of the casing 1 prevent the device from slipping off. Then, the collection port 14 collects indoor air. The sensor 10 detects the air through electrical signals and resistive elements. The detected air data is then processed by the Cortex-M processor 9 and transmitted to the display panel 3 via the wire 11 for display. If the device is accidentally dropped during use, the damping spring 5 at the bottom of the protective plate 13 will extend and retract upon impact. The spring will first undergo elastic deformation to absorb most of the impact energy. At the same time, the internal damper will extend and retract, converting the impact energy into heat energy. The spring and damper work together to reduce the impact on the control board 8 inside the device. Simultaneously, the buffer column 7 in the buffer pad 6 at the bottom of the damping spring 5 will extend and retract to buffer the remaining impact, thus protecting the control board 8, processor 9, and sensor 10 inside the device.
