Description

Technical Field

[0001] This application relates to the field of ambient air detector technology, and in particular to an ambient air detector that is easy to install. Background Technology

[0002] This air quality detector uses all imported sensors and can simultaneously detect formaldehyde, PM2.5, TVOC, and temperature and humidity. It is a five-in-one air quality detector. Through its internal original imported sensors, it can accurately measure pollutant concentrations and calculate the Air Quality Index (AQI). It will alarm when the concentration exceeds the standard. The principle of the air quality detector is to detect the signals from the front-end formaldehyde sensor, PM2.5 sensor, TVOC sensor, and temperature and humidity sensor. The weak signals from the sensors are amplified by an operational amplifier and noise interference is removed by a filtering circuit. Then, the data is collected by an AD converter and processed by a 32-bit high-precision CPU. Finally, the data is converted into pollutant concentration values ​​and displayed on the LCD screen.

[0003] For example, Chinese utility model patent CN222105438U discloses an ambient air detector that is easy to install. In use, the ambient air detector body is installed on the top of the mounting plate. Pulling the pull plate outward will cause the second rack plate to slide outward, thereby deforming the spring on the outside of the connecting rod. Then, the buckle plate is fastened to both sides of the ambient air detector body. The fixing plate at the bottom of the ambient air detector body will penetrate the mounting plate. Releasing the pull plate will cause the second rack plate to engage with the first rack plate, thereby limiting and fixing the ambient air detector body, making it easy to assemble and disassemble.

[0004] Regarding the aforementioned technologies, the inventors believe that the ambient air detectors in these technologies are difficult to adjust the installation angle of the detector according to requirements during use, thereby reducing the practicality of the device.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0021] This application discloses an easy-to-install ambient air detector, referring to... Figure 1-3 The device includes a base 1 and a detector 8. A lifting sleeve 2 is fixedly installed on the top of the base 1. A lifting rod 4 is slidably arranged inside the lifting sleeve 2. A rotating sleeve 6 is rotatably arranged on the top of the lifting rod 4. Two support rods 7 are symmetrically installed on the outer wall of the rotating sleeve 6. The detector 8 is fixedly installed on the top of the two support rods 7. A rotating assembly 5 for driving the rotating sleeve 6 to rotate is provided on the lifting rod 4. The rotating assembly 5 includes a rotating shaft 51 rotatably arranged inside the lifting rod 4. A first bevel gear 52 is fixedly installed on the outer side of the rotating shaft 51. A second bevel gear 53 is meshed with the top of the first bevel gear 52. The second bevel gear 53 is fixedly installed on the bottom wall of the rotating sleeve 6.

[0022] Here, by rotating the shaft 51, the shaft 51 can drive the first bevel gear 52 to rotate. The first bevel gear 52 meshes with the second bevel gear 53, which can drive the rotating sleeve 6 to rotate. The rotating sleeve 6 can drive the detector 8 to rotate through the support rod 7, thereby realizing the adjustment of the angle of the detector 8 and improving the practicality of the device.

[0023] Reference Figure 3 The rotating shaft 51 is located on both sides of the lifting rod 4 and is threadedly connected to the locking nut 55. The end of the rotating shaft 51 is fixedly installed with a turntable 54, and the turntable 54 has multiple anti-slip grooves in the circumferential direction.

[0024] By tightening the locking nut 55, the rotating shaft 51 can be limited, which improves the stability of the rotating sleeve 6.

[0025] Reference Figure 1 The top of each of the two support rods 7 is fixedly connected to a mounting base 71, and the mounting base 71 has a mounting hole. The detector 8 is fixedly installed by connecting bolts passing through the mounting hole.

[0026] Here, a mounting base 71 is connected to the top of the support rod 7, and the mounting base 71 has a mounting hole, which makes it easy to assemble and disassemble the detector 8.

[0027] Reference Figure 1 and Figure 2 The inner wall of the lifting sleeve 2 is symmetrically provided with limit grooves, and two limit strips 41 are symmetrically installed on the outer wall of the lifting rod 4. The limit strips 41 slide inside the limit grooves.

[0028] Here, by installing a limit strip 41 on the outer wall of the lifting rod 4, and providing a limit groove inside the lifting sleeve 2 that matches the limit strip 41, the up and down movement of the lifting rod 4 can be limited.

[0029] Reference Figure 1 The lifting sleeve 2 is threaded with a positioning bolt 3 to limit the sliding of the lifting rod 4.

[0030] The positioning bolt 3 is provided here so that the extension height of the lifting rod 4 can be adjusted and locked.

[0031] The implementation principle of an easy-to-install ambient air detector according to an embodiment of this application is as follows: In use, the device is fixedly installed in a designated position by the base 1. When the device needs to adjust the angle, the turntable 54 can be rotated, which can drive the rotating shaft 51 to rotate. The rotating shaft 51 can drive the rotating sleeve 6 to rotate through the first bevel gear 52 meshing with the second bevel gear 53. The rotating sleeve 6 drives the detector 8 to rotate through the support rod 7 and the mounting base 71, thereby adjusting the angle of the detector 8. Then, by tightening the locking nut 55, the rotating shaft 51 is limited to ensure the stability of the detector 8. Next, by loosening the positioning bolt 3, the lifting rod 4 can be moved up and down to adjust the height of the detector 8. Then, the positioning bolt 3 is tightened.
