Description

Technical Field

[0001] This utility model relates to the field of air detection devices, specifically to a multi-directional air detection device. Background Technology

[0002] With social development and technological progress, the field of air testing technology has also seen significant development and progress. Air testing refers to the detection of the composition of air. It mainly focuses on indoor air testing from an application perspective. It is used to detect whether indoor decoration materials, furniture, etc. contain substances that are harmful to the human body and are released into the home and office environment, causing decoration pollution, and to detect air quality.

[0003] Chinese patent discloses a multi-directional air detection device (authorization announcement number CN 220416658 U). This patented technology can solve the problem that "most existing air detection devices do not have the function of automatic up-and-down rotation detection. When detecting indoor air, they can only detect the air in one direction. Since air moves in all directions, existing air detection devices cannot detect multiple directions, thus reducing the detection effect." However, when the above patent performs multi-directional detection, it usually directly drives the detection device to rotate without allowing sufficient detection time, resulting in unsatisfactory detection results. Furthermore, when performing up-and-down detection, there is a lack of positioning structure for the connecting frame, making it difficult to detect slight tilting of the connecting frame. This increases the risk of breakage of the connecting frame, and the detection device is prone to loosening and flying off when rotating, lacking further limiting structure for the detection device. Utility Model Content

A main shaft is installed on the upper surface of the base, and a circular disk is installed on the end face of the main shaft. The detector body is installed on the upper surface of the circular disk by welding. A driven gear is installed on the outer wall of the main shaft, and a driving gear is meshed and rotated on the outer wall of the driven gear. An adjustment motor is installed at the bottom of the driving gear. Side frames are symmetrically installed on the left and right side walls of the base. Lower platforms are symmetrically installed on the left and right sides below the base. An electric slider is installed on the outer end of the lower platform.

The other end of the connecting rod is installed at the bottom of the side frames. A base plate is installed at the bottom of the lower platform, and casters are installed at the bottom of the base plate.

[0005] Preferably, the upper surface of the lower platform is provided with a sliding groove, and an inner platform is installed in the sliding groove by means of sliding fit, and a base is installed on the upper surface of the inner platform.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0018] Please see Figures 1-5 This embodiment provides a multi-directional air detection device, including a base 1 and a detector body 2. A main shaft 11 is mounted on the upper surface of the base 1, and a circular disk 12 is mounted on the end face of the main shaft 11. The detector body 2 is mounted on the upper surface of the circular disk 12 by welding. A driven gear 13 is mounted on the outer wall of the main shaft 11, and a driving gear 14 is meshed and rotated on the outer wall of the driven gear 13. An adjusting motor 15 is mounted at the bottom of the driving gear 14. Side frames 16 are symmetrically mounted on the left and right side walls of the base 1, and lower platforms 17 are symmetrically mounted on the left and right sides below the base 1. An electric slider 18 is mounted on the outer end of the lower platform 17, and a connecting seat 19 is mounted on the electric slider 18 by sliding engagement. A connecting rod 21 is mounted on the outer end of the connecting seat 19, and the other end of the connecting rod 21 is mounted on the side frame 1. At the bottom of the lower platform 17, a base plate is installed, and casters 22 are installed on the bottom of the base plate. The electric slider 18 is a linear guide slider structure. The operation of the device is controlled by the motor driving the lead screw to rotate. During operation, the air quality is detected by the detector body 2. The regulating motor 15 is started, driving the drive gear 14 to rotate. The drive gear 14 is an incomplete gear structure, which can drive the drive gear 14 to rotate intermittently. The detector body 2 rotates intermittently. Compared with the continuous rotation of the detector body 2, it can provide sufficient detection time for the detector body 2, which further improves the detection effect of air quality. The electric slider 18 is started, which can drive the detector body 2 to move up and down, which is convenient for detecting the air quality at different heights.

[0019] The upper surface of the lower platform 17 is provided with a sliding groove, and an inner positioning plate 23 is installed in the sliding groove by means of sliding fit. A base platform 1 is installed on the upper surface of the inner positioning plate 23. During operation, the inner positioning plate 23 plays a positioning role for the base platform 1. The sliding fit ensures the stability of the inner positioning plate 23 when moving up and down.

[0020] The connecting seat 19 is symmetrically equipped with a positioning plate 24 at its front and rear ends. A positioning post 25 is installed on the upper surface of the positioning plate 24. A positioning plate 26 is symmetrically installed at the outer end of the lower platform 17. A through hole is opened on the upper surface of the positioning plate 26. An annular groove is opened on the outer wall of the positioning post 25. A cotton pad 27 is installed on the outer end of the annular groove by means of a sleeve. When the electric slider 18 is started during operation, the connecting seat 19 moves up and down, and the positioning plate 24 moves up, so that the positioning post 25 passes through the through hole, thereby positioning the connecting frame. This avoids the connection frame from being slightly misaligned after long-term operation, which is difficult to detect and may easily break after continued use. When the connecting frame is misaligned, the positioning post 25 hits the positioning plate 26, and the cotton pad 27 provides shock absorption and protection, preventing the device from being damaged further.

[0021] A pin 28 is rotatably mounted on the upper surface of the circular disk 12 via a pin shaft. A limit bracket 29 is mounted on the upper surface of the pin 28. A screw hole is opened on the inner end of the limit bracket 29, and a first screw 291 is screwed to the inner end of the screw hole. A positioning groove is opened on the outer wall of the first screw 291, and a positioning plug 292 is installed in the positioning groove by snap-fit. A connecting plate 293 is mounted on the upper surface of the positioning plug 292. During operation, the first screw 291 connects to the limit bracket 29, and the connecting bracket limits the detection instrument body 2, thereby preventing slippage when the detection instrument body 2 rotates, further ensuring the stability of the installation of the detection instrument body 2. The positioning plug 292 limits the first screw 291 to prevent relative rotation of the first screw 291.

[0022] In actual operation, the air quality is detected and processed by the detector body 2. The regulating motor 15 is started, driving the drive gear 14 to rotate. The drive gear 14 has an incomplete gear structure, which allows it to rotate intermittently. The detector body 2 rotates intermittently, which provides sufficient detection time compared to continuous rotation of the detector body 2, further improving the detection effect of air quality. The electric slider 18 is started, which drives the detector body 2 to move up and down, making it convenient to detect and process air quality at different heights.
