Description

Technical Field

[0001] The utility model relates to the technical field of air samplers, in particular to an air sampler for indoor environment detection. Background Art

[0002] Indoor environmental testing refers to the process of monitoring and evaluating indoor air quality, temperature, humidity, light and other parameters. This test is designed to ensure that the indoor environment meets health, comfort and safety standards to protect the health and comfort of residents, staff or other people who are active indoors. Air quality testing is one of the core contents of indoor environmental testing. Air quality testing includes monitoring and evaluating the concentration of various pollutants in the air (such as formaldehyde, volatile organic compounds, nitrogen oxides, particulate matter, etc.), as well as evaluating the ventilation conditions of indoor air. This test requires the use of an air sampler for indoor environmental testing.

[0003] In the structure of a traditional air sampler for indoor environmental monitoring, the sampling head is the component that contacts the indoor environment and collects air samples. It typically includes an air inlet and a filter to prevent large particles from entering and contaminating the sample. The sampler is usually equipped with multiple gas sampling channels, each dedicated to collecting different types of pollutants. These channels can be operated independently to ensure accurate monitoring of different pollutant levels. The device is also equipped with a fixed bracket and a connecting base to ensure stable detection indoors.

[0004] However, the bracket structure of the traditional air sampler used for indoor environment detection is often a fixed structure, with its shell made of plastic or metal. The sampling head bracket is located on the top of the sampler and is used to fix and support the sampling head. The sampling head is often unable to move and samples at a fixed position. This structure may result in the sampling content being relatively single, and it is impossible to detect and evaluate a large range of indoor air, which reduces the detection accuracy. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an air sampler for indoor environment detection, which aims to improve the support structure of traditional air samplers for indoor environment detection, which is often a fixed structure, and the sampling head is often unable to move, making it impossible to detect and evaluate the air in a large area indoors, thereby reducing the detection accuracy.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an air sampler for indoor environment detection, comprising a fixed platform, the side wall of the fixed platform is fixedly connected to a hydraulic rod, the output end of the hydraulic rod is fixedly connected to a slide platform one, the side wall of the fixed platform is fixedly connected to a slide rail, the slide platform one is slidably connected to the side wall of the slide rail, the side wall of the fixed platform is fixedly connected to an inclined plate, one side wall of the slide platform is fixedly connected to a support platform, a connecting column is rotatably connected to the inside of the support platform, the bottom of the connecting column is fixedly connected to a connecting plate, the connecting plate is rotatably connected to the inside of the connecting plate, the top of the connecting column is fixedly connected to a sampling head, and a fixed component is provided at the bottom of the fixed platform.

[0007] Furthermore, the fixing assembly includes a base, and the base is arranged at the bottom of the fixing platform.

[0008] Furthermore, a tray is fixedly connected to the top of the base, and a motor is provided at the bottom of the tray.

[0009] Furthermore, the output end of the motor is fixedly connected to a turntable, and the side wall of the turntable is rotatably connected to a plurality of connecting rods.

[0010] Furthermore, a plurality of slide grooves are provided inside the tray, and a plurality of slide platforms 2 are provided inside the tray.

[0011] Furthermore, the second slide is slidably connected to the inside of the slide groove, and one end of the connecting rod is rotatably connected to the bottom of the second slide.

[0012] Furthermore, the top of each of the second slides is fixedly connected to a turntable, and the inside of the turntable is rotatably connected to a second connecting rod.

[0013] Furthermore, a fixed column is fixedly connected to the top of the tray, a sliding column is slidably connected inside the fixed column, and one end of the connecting rod is slidably connected to the side wall of the sliding column.

[0014] The utility model has the following beneficial effects:

[0015] 1. In the present invention, the hydraulic rod is used to push the slide to slide on the side wall of the slide rail, and then the pulley touches the inclined plate and drives the connecting column to rotate inside the support. In this way, the movement and rotation of the sampling head can be realized, so that the sampling range of the sampling head is expanded, the sampling structure has diversity, and the indoor air quality detection and evaluation is more accurate.

[0016] 2. In the present invention, the turntable is driven to rotate by a motor so that the connecting rod 1 pulls the slide 2 to slide inside the tray, and then the connecting rod 2 drives the slide column to slide inside the fixed column. Due to this structure, the height of the air sampler can be freely adjusted to adapt to indoor environments of different heights, thereby improving the applicability of the device.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an air sampler for indoor environment detection, including a fixed platform 1, a hydraulic rod 2 is fixedly connected to the side wall of the fixed platform 1, a slide 4 is fixedly connected to the output end of the hydraulic rod 2, a slide rail 3 is fixedly connected to the side wall of the fixed platform 1, the slide 4 is slidably connected to the side wall of the slide rail 3, the side wall of the fixed platform 1 is fixedly connected to an inclined plate 9, the side wall of the slide 4 is fixedly connected to a support platform 5, the support platform 5 is internally rotatably connected to a connecting column 6, the bottom of the connecting column 6 is fixedly connected to a connecting plate 7, the connecting plate 7 is internally rotatably connected to a pulley 8, the top of the connecting column 6 is fixedly connected to a sampling head 10, and a fixed component is provided at the bottom of the fixed platform 1.

[0024] Specifically, once the hydraulic rod 2 applies a push-pull force, it drives the slide 4 to move on the side wall of the slide rail 3. The movement of the slide 4 drives the synchronous displacement of the support 5 and causes the connecting column 6 to displace inside the support 5. The connecting plate 7 at the bottom of the connecting column 6 rotates with the movement of the support 5. This rotation process is affected by the pulley 8 on the side wall of the inclined plate 9. As the connecting plate 7 rotates and the tilt angle changes, the connecting column 6 will also rotate accordingly inside the support 5. This rotation ultimately affects the angle of the sampling head 10, so that the sampling head 10 can move and rotate in the horizontal and vertical directions. This design makes the sampling range of the sampling head 10 wider, and the diversity of the sampling structure also increases the accuracy of the detection and evaluation of indoor air quality.

[0025] Reference Figure 1 and Figure 3 The fixed component includes a base 11, which is arranged at the bottom of the fixed platform 1, and a tray 12 is fixedly connected to the top of the base 11. A motor 13 is arranged at the bottom of the tray 12, and a turntable 14 is fixedly connected to the output end of the motor 13. The side wall of the turntable 14 is rotatably connected to a plurality of connecting rods 15. A plurality of slide grooves 17 are opened inside the tray 12, and a plurality of slides 16 are arranged inside the tray 12. The slides 16 are slidably connected inside the slide grooves 17. One end of the connecting rod 15 is rotatably connected to the bottom of the slides 16. Each slide 16 is fixedly connected to a turntable 18 at the top, and a connecting rod 2 19 is rotatably connected inside the turntable 18. A fixed column 20 is fixedly connected to the top of the tray 12, and a sliding column 21 is slidably connected inside the fixed column 20. One end of the connecting rod 2 19 is slidably connected to the side wall of the sliding column 21.

[0026] Specifically, the motor 13 starts to generate a rotational force, causing the turntable 14 to start rotating. As the turntable 14 rotates, the multiple connecting rods 15 on the top will also rotate and change their inclination angles. The movement of these connecting rods 15 pulls the slide 16 to slide in the slide groove 17 in the tray 12. Through the movement of the slide 16, the connecting rod 19 in the turntable 18 will also rotate accordingly and change its inclination angle. The connecting rod 19 applies a push-pull force to the sliding column 21, causing the sliding column 21 to move inside the fixed column 20, thereby changing the sampling height of the device. Due to this structure, the height of this air sampler can be freely adjusted to adapt to indoor environments of different heights, thereby improving the applicability of this device.

[0027] Working principle: When this air sampler is needed to sample indoor air, first start the hydraulic rod 2. The hydraulic rod 2 outputs a push-pull force to the slide 4, driving the slide 4 to slide on the side wall of the slide rail 3. While the slide 4 slides, it drives the support 5 on its side wall to move synchronously. The support 5 can drive the connecting column 6 inside it to move. In the process of following the movement, the connecting plate 7 at the bottom of the connecting column 6 slides on the side wall of the inclined plate 9, thereby driving the connecting plate 7 to rotate and change the inclination angle. At this time, the connecting column 6 rotates inside the support 5. The rotation of the connecting column 6 can change the angle of the sampling head 10, thereby realizing the movement and rotation of the sampling head 10, expanding the sampling range of the sampling head 10, and making the sampling structure diverse, which is beneficial for the detection and evaluation of indoor air quality. More accurately, when the air sampling height of this device needs to be changed, start the motor 13, and the motor 13 outputs a rotating force to the turntable 14 to drive the turntable 14 to rotate. While the turntable 14 rotates, it drives the multiple connecting rods 15 on its top to rotate and change its own inclination angle. At this time, the connecting rod 15 pulls the slide 2 16 and drives the slide 2 16 to slide in the slide groove 17 inside the tray 12. The sliding of the slide 2 16 makes the connecting rod 2 19 inside the turntable 18 rotate and change its own inclination angle. The connecting rod 2 19 can push and pull the sliding column 21 so that the sliding column 21 slides inside the fixed column 20. At this time, the sampling height of the device can be changed. Due to this structure, the height of this air sampler can be freely adjusted to adapt to indoor environments of different heights, thereby improving the applicability of this device.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
