Description
Technical Field
[0001] This utility model relates to the technical field of negative oxygen ion monitoring instruments, and in particular to a negative oxygen ion monitoring instrument. Background Technology
[0002] Negative ion monitors are important environmental monitoring devices, widely used in air quality assessment, forest health and wellness area monitoring, and other fields. With the increasing demand for environmental monitoring, these monitors need to operate continuously in complex environments for extended periods, making the cleaning of their data display screens an increasingly prominent issue.
[0003] Dampen a microfiber cloth with a small amount of water, wring it out, and gently wipe the screen to remove surface stains and fingerprints. Maintain even pressure and wipe in one direction only to avoid scratching.
[0004] In existing technologies, the cleaning of some negative ion monitors generally relies on manual wiping or natural rainwater rinsing. However, manual cleaning is inefficient and cannot achieve high-frequency maintenance, while rainwater rinsing is limited by weather conditions and the cleaning effect is unstable, resulting in poor cleaning efficiency. Therefore, in order to address the above shortcomings, a negative ion monitor is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a negative oxygen ion monitor, which aims to improve the problem that some negative oxygen ion monitors in the prior art require manual or rainwater cleaning for screen cleaning, which is unstable and inefficient.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A cleaning mechanism is fixedly connected to the front side of the cover plate. A spring mechanism is fixedly connected to the top front side of the housing. A disassembly mechanism is provided at the top of the cleaning mechanism. A wire harness mechanism is fixedly connected to the rear side of the housing.

[0013] A protective base is fixedly connected to the bottom of the housing of the negative oxygen ion monitor, and pressure sensors are fixedly connected to both ends of the flexible scraper.
[0014] The above technical solution provides bottom protection through a protective base, and a pressure sensor monitors the contact pressure between the flexible scraper and the display screen in real time. All components work together to ensure the safety and effectiveness of the cleaning process, while preventing excessive scraping force from damaging the display screen surface.
[0015] As a further description of the above technical solution:
[0016] The disassembly mechanism includes a sliding rod, which is slidably connected to the inside of the strip plate. A spring is sleeved on the outside of the sliding rod. A connecting plate is fixedly connected to the rear side of the sliding rod. Rotating plates are rotatably connected to both ends of the connecting plate. An opening plate is fixedly connected to the far side of the two rotating plates. A limiting plate is rotatably connected inside the opening plate.

[0017] The above technical solution achieves position adjustment by sliding the sliding rod within the strip plate, provides reset force by spring 1, connects the rotating plate to form a linkage structure, and uses the opening plate and the limiting plate to achieve locking function. The sliding connection between the limiting plate and the sliding plate ensures stability. The coordinated operation of all components enables the cleaning mechanism to be quickly disassembled and maintained.

[0019] The elastic mechanism includes multiple torsion springs, the bottom ends of which are fixedly connected to the top side of the strip plate, and the top ends of two torsion springs are fixedly connected to hinges. The rear sides of the two hinges are respectively fixedly connected to the top front side of the negative oxygen ion monitor housing.
[0020] The above technical solution provides elastic restoring force through a torsion spring, and the hinge connects the negative ion monitor housing and the strip plate to form a rotation fulcrum.

[0024] As a further description of the above technical solution:
[0025] The rear side of the electrostatic adsorption layer is slidably connected to the front side of the display screen, and the left side of the slide plate is fixedly connected to the right side of the strip plate.
[0026] The above technical solution achieves dust adsorption through contact between the electrostatic adsorption layer and the display screen, while the sliding plate connects to the strip plate to transmit driving force.

[0030] This utility model has the following beneficial effects:
[0031] 1. In this utility model, the motor is started every six hours by the timer module. The motor drives the threaded rod to rotate, which drives the slide plate to move in a straight line. Then, the strip plate slides, which causes the strip plate to drive the flexible scraper and the electrostatic adsorption layer to slide back and forth along the front side of the display screen. The flexible scraper first scrapes off large particles of dirt, and the electrostatic adsorption layer then adsorbs fine dust, thereby enabling automatic large-area cleaning and improving cleaning efficiency.
[0032] 2. In this utility model, by driving the rotating plate to rotate, the rotating plate drives the opening plate to rotate, thereby driving the limiting plate to slide, so that the limiting plate slides away from the top of the sliding plate. Then the flexible scraper can drive the two sliding plates to slide away from the inside of the strip plate, extending the service life of the equipment and reducing maintenance costs.
[0033] 3. In this utility model, by compressing the second spring, the second spring can store elastic potential energy, and then apply a force in the opposite direction to the clamping plate to reset it. Then, the two clamping plates can slide to the same side and fix the power head or other connector, thereby improving the stability of monitoring. Attached Figure Description

[0041] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0042] Reference Figures 1 to 2 This utility model provides an embodiment of a negative ion monitor, including a negative ion monitor housing 1, which serves as the main frame of the entire instrument and provides protection and support for the internal electronic components. This is prior art and will not be described in detail here. A protective seat 2 is fixedly connected to the bottom of the negative ion monitor housing 1, providing good anti-slip properties and ensuring that the monitor can be placed stably on various surfaces. A display screen 4 is provided at the front of the negative ion monitor housing 1 through a cover plate 3. The display screen 4 is used to limit the collected data. A cleaning mechanism 5 is fixedly connected to the front side of the cover plate 3. The cleaning mechanism 5 is used to clean the display screen 4. The cleaning mechanism 5 includes two support plates 51. The rear sides of the two support plates 51 are fixedly connected to the front side of the cover plate 3 and are fixed by welding, thereby providing support for the support plates 51. A drive assembly 53 is fixedly connected to the top front side of the cover plate 3. The drive assembly 53 includes two top plates 5305. The rear sides of the two top plates 5305 are respectively fixedly connected to the top front side of the cover plate 3 and are fixed by welding, thereby providing support for the top plates 5305.
[0043] One of the top plates 5305 has a motor 5301 (model 28 BYJ-48) fixedly connected internally. A threaded rod 5302 is fixedly connected to the drive end of the motor 5301. Starting the motor 5301 drives the threaded rod 5302 to rotate. A timer module 5303 is fixedly connected to the top of the motor 5301. The timer module 5303 is designed to clean every six hours. A sliding plate 5304 is bolted to the outside of the threaded rod 5302. Rotation of the threaded rod 5302 causes the sliding plate 5304 to slide up and down. A column 54 is fixedly connected to the top side of one of the support plates 51 through welding, providing support for the column 54. A sliding plate 5304 is slidably connected to the outside of the column 54. 5. The support column 54 restricts the sliding plate 55 so that it can slide stably. The right side of the sliding plate 55 is fixedly connected to the strip plate 56, which is fixed by welding to provide support for the strip plate 56. The left side of the sliding plate 5304 is fixedly connected to the right side of the strip plate 56. The sliding plate 5304 drives the strip plate 56 to slide synchronously. There are two sliding plates 52 slidably connected inside the strip plate 56. The restriction of the strip plate 56 allows the sliding plates 52 to slide stably. The back side of the two sliding plates 52 is fixedly connected to a flexible scraper 57, which is made of polyurethane material with a thickness of 2 mm. The flexible scraper 57 forms a 15-degree angle with the screen. The back side of the flexible scraper 57 is fixedly connected to an electrostatic adsorption layer 58, which is a carbon fiber fabric composite PTFE film.
[0044] Specifically, automatic maintenance of the display screen 4 is achieved through cleaning. The cleaning mechanism 5 uses a stepper motor 5301 to drive the threaded rod 5302 to move the slide plate 5304 vertically. The linkage strip plate 56 makes the polyurethane flexible scraper 57 adhere to the screen surface at a 15-degree angle. The integrated timer module 5303 controls the cleaning cycle that starts every 6 hours. In conjunction with the carbon fiber-PTFE composite electrostatic adsorption layer 58, dust particles are removed simultaneously, forming a dual cleaning mechanism of "mechanical scraping plus electrostatic adsorption". This not only avoids scratching the screen but also effectively removes static charge dust, ensuring the long-term reliability of the monitoring data visualization.
[0045] Reference Figures 1 to 3The rear side of the electrostatic adsorption layer 58 is slidably connected to the front side of the display screen 4. The display screen 4 is thoroughly cleaned by the up-and-down sliding of the electrostatic adsorption layer 58. The top front side of the negative ion monitor housing 1 is fixedly connected to the elastic mechanism 6. The elastic mechanism 6 includes multiple torsion springs 61. The bottom ends of the multiple torsion springs 61 are fixedly connected to the top side of the strip plate 56 and fixed by welding process, thereby providing support for the strip plate 56. The top ends of the two torsion springs 61 are fixedly connected to the hinges 62. The rear sides of the two hinges 62 are respectively fixedly connected to the top front side of the negative ion monitor housing 1 and fixed by welding process, thereby providing support for the hinges 62. The top of the cleaning mechanism 5 is provided with a disassembly mechanism 7. The disassembly mechanism 7 includes a sliding rod 71. The outside of the sliding rod 71 is slidably connected to the inside of the strip plate 56. The sliding rod 71 can slide stably by the restriction of the strip plate 56. The outside of the sliding rod 71 is fitted with a spring 72. By restricting the spring 72, the spring 72 can be evenly stressed.
[0046] The front side of spring 72 is fixedly connected to the front side of the inner wall of strip plate 56. By fixing spring 72, the force distribution of spring 72 is made uniform. The rear side of sliding rod 71 is fixedly connected to connecting plate 73. During the sliding process, sliding rod 71 drives connecting plate 73 to slide synchronously. The rear end of spring 72 is fixedly connected to the front side of connecting plate 73. During the sliding process, connecting plate 73 will compress spring 72, allowing spring 72 to store elastic potential energy, and then give connecting plate 73 a force in the opposite direction to reset it. Both ends of connecting plate 73 are rotatably connected. There is a rotating plate 74, which is driven to rotate by the connecting plate 73 during the sliding process. An open plate 75 is fixedly connected to the far side of the two rotating plates 74. The rotating plate 74 transmits the rotational force to the open plate 75, so that the open plate 75 can slide horizontally. The inside of the open plate 75 is rotatably connected to a limiting plate 76. The opening plate 75 transmits the rotational force to the limiting plate 76, so that the limiting plate 76 slides horizontally. The bottom side of the limiting plate 76 is slidably connected to the sliding plate 52. The limiting plate 76 slides to the top of the sliding plate 52 to restrict the sliding plate 52.
[0047] Specifically, the elastic mechanism 6 uses a combination of torsion spring 61 and hinge 62 to provide dynamic pressure compensation for the strip plate 56, ensuring that the flexible scraper 57 always adheres to the display screen 4 with constant pressure. The disassembly mechanism 7 uses a sliding rod 71 pushed by spring 72 to drive the rotating plate 74, which in turn drives the opening plate 75 and the limiting plate 76 to form a "press-to-unlock" quick-release structure, enabling one-handed installation and removal of the sliding plate 52. The whole system forms a maintenance mechanism of "elastic clamping plus one-button disassembly", which not only ensures the operational stability of the cleaning components, but also facilitates the replacement of consumable parts.
[0048] Reference Figure 1 , Figure 4 and Figure 5 A wiring mechanism 8 is fixedly connected to the rear side of the negative ion monitor housing 1. The wiring mechanism 8 includes two fixing plates 81. The front sides of the two fixing plates 81 are fixedly connected to the rear side of the negative ion monitor housing 1 by welding, thereby providing support for the fixing plates 81. Two fixing blocks 82 are fixedly connected to adjacent sides of the two fixing plates 81 by welding, thereby providing support for the fixing blocks 82. Connecting rods 83 are fixedly connected inside the two fixing blocks 82 by welding, thereby providing support for the connecting rods 83. Provide support, with springs 84 sleeved at both the upper and lower ends of the connecting rod 83. By restricting the springs 84, the springs 84 can be evenly stressed. Two clamping plates 85 are slidably connected to the outside of the two connecting rods 83. By restricting the connecting rods 83, the clamping plates 85 can slide stably. A gripping plate 86 is fixedly connected to the rear side of the clamping plate 85. By pushing the gripping plate 86, the clamping plate 85 can be rotated. Pressure sensors 9 are fixedly connected to both the left and right ends of the flexible scraper 57 to detect the contact pressure between the flexible scraper 57 and the display screen 4.
[0049] Specifically, cable management and cleaning pressure monitoring are achieved through a modular structure. The cable management mechanism 8 uses a fixed plate 81 and a connecting rod 83 to form a frame base. It works with a clamping plate 85 pre-tightened by a spring 84 to form an elastic clamping space. The cable can be quickly fixed or released by one hand through the grip plate 86. The pressure sensor 9 is integrated at both ends of the flexible scraper 57 to monitor the contact pressure between the cleaning mechanism 5 and the display screen 4 in real time, forming a composite of "elastic cable management plus pressure feedback". This ensures the neat management of the equipment cables and adjusts the adhesion of the cleaning components to ensure the screen cleaning effect and prevent excessive wear.
[0050] Working principle: The timing module 5303 starts the 28BYJ-48 type motor 5301 every six hours. The motor 5301 drives the threaded rod 5302 to rotate, which drives the slide plate 1 5304 to move linearly along the axis, thereby causing the strip plate 56 connected to it to move synchronously. The slide plate 2 55 connected to the strip plate 56 slides stably under the restriction of the column 54. At this time, the sliding plate 52 in the strip plate 56 drives the flexible scraper 57 with a 15-degree angle to the screen and the electrostatic adsorption layer 58 made of carbon fiber fabric composite PTFE film on the back side to slide up and down along the front side of the display screen 4. The flexible scraper 57 first scrapes away large particles of dirt, and the electrostatic adsorption layer 58 then adsorbs tiny dust particles.
[0051] When the flexible scraper 57 needs to be disassembled for maintenance, pull the sliding bar 71 forward, and then drive the connecting plate 73 to slide and compress the spring 72, so that the spring 72 can store elastic potential energy, and then give the connecting plate 73 a force in the opposite direction to reset it, and then drive the rotating plate 74 to rotate, and then drive the opening plate 75 to rotate, thereby driving the limiting plate 76 to slide, so that the limiting plate 76 slides away from the top of the sliding plate 52, and then the flexible scraper 57 can drive the two sliding plates 52 to slide away from the inside of the strip plate 56;
[0052] In daily use, when connecting power cords and other cables, the clamping plate 85 is slid by holding the gripping plate 86, which will then compress the second spring 84, allowing the second spring 84 to store elastic potential energy. This will then give the clamping plate 85 a force in the opposite direction to reset it. The two clamping plates 85 can then slide to the same side to fix the power head or other connectors.
[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
