Description

Technical Field

[0001] This utility model relates to the field of display screen technology, and in particular to a dust removal and drying device for LCD liquid crystal display screen production. Background Technology

[0002] Liquid crystal displays, also known as LCDs, are flat, ultra-thin display devices. They consist of a number of color or monochrome pixels placed in front of a light source or reflector. LCDs have low power consumption and are suitable for battery-powered electronic devices. The main principle of an LCD is to use an electric current to stimulate liquid crystal molecules to produce dots, lines, and surfaces, which, together with a backlight, form an image. After a period of use, dust tends to accumulate on the LCD screen, requiring regular cleaning to avoid affecting the viewing experience.

[0003] As disclosed in the utility model with authorization announcement number CN221573414U, an LCD screen with dust removal and drying function is provided. The motor drives the threaded rod to rotate, which can move the brush in front of the display screen to sweep the dust in front of the display screen into the storage box. By setting multiple springs to push the brush to stick to the display screen, the cleaning effect can be improved. By setting a fan to blow air into the inside of the casing, the water vapor accumulated inside the casing can be dried. The filter plate can prevent dust from entering the inside of the casing, thereby achieving the effect of dust removal and drying.

[0004] The existing technology still has the following problems when used:

[0005] The motor-driven brush of this device requires the connecting parts and moving blocks on the outside of the threaded rod and guide rod to move up and down. The connecting parts pass through the outer shell, so the surface of the outer shell is provided with vertical grooves to facilitate the up and down movement of the connecting parts. The vertical grooves are easily blocked by dust accumulation when exposed to the external environment for a long time, which affects the up and down movement of the connecting parts. A storage box is slidably connected to the bottom of the outer shell of this device. The storage box is prone to wobbling back and forth when not in use. Utility Model Content

[0024] Example

[0025] Please refer to Figures 1-3As shown, this utility model provides a dust removal and drying device for LCD screen production, including an LCD screen housing 1, a display screen 2, and a storage box 3. The display screen 2 is installed on the front of the LCD screen housing 1. The storage box 3 and the slide groove 12 are provided at the bottom of the LCD screen housing 1. The storage box 3 is adapted to the slide groove 12 and is slidably connected to the LCD screen housing 1 through the slide groove 12. The storage box 3 can collect and catch the dust falling from above by moving outward. An electric fan 4 and a filter plate 5 are respectively installed on the left and right sides of the LCD screen housing 1. The filter plate 5 can prevent external dust from entering the interior of the LCD screen housing 1. Controlling the electric fan 4 to blow air outward can drive the airflow inside the LCD screen housing 1. The airflow accelerates the evaporation of water vapor inside the LCD screen housing 1 and prevents water vapor from accumulating inside the LCD screen housing 1 and causing wear on the circuit.

[0026] like Figures 1-4 As shown, a cleaning assembly is provided on the outer surface of the LCD display housing 1. The cleaning assembly consists of a mounting plate 6, a brush 7, rollers 9, a fixing plate 10, and a fixing shaft 15. The mounting plate 6 is located on the bottom surface of the LCD display housing 1. The brush 7 and symmetrical fixing shafts 15 are fixedly mounted on the bottom surface of the mounting plate 6. The brush 7 is relatively soft and can rotate. The fixing plate 10 is fixedly mounted on the bottom surface of the fixing shaft 15. Rollers 9 are rotatably connected between the mounting plate 6 and the fixing plate 10. The fixing shaft 15 passes through the rollers 9 and is rotatably connected to them. Symmetrical support plates 8 are fixedly connected to the left and right sides of the mounting plate 6. The support plates 8, together with the fixing plates 10, can support the LCD display housing 1, improving its stability. When cleaning the front surface of the display screen 2 is required, the mounting plate 6 is removed and moved to the LCD display housing. Above the housing 1, the roller 9 is aligned with the left and right sides of the LCD housing 1 and the mounting plate 6 is moved downwards. This allows the roller 9 to contact the left and right sides of the LCD housing 1 and roll downwards along them. At the same time, the brush 7 moves downwards close to the display screen 2. The up-and-down movement of the mounting plate 6 can drive the brush 7 to move up and down, thereby cleaning the surface of the display screen 2. There is a certain friction between the left and right sides of the LCD housing 1 and the outer side of the roller 9, which prevents the roller 9 from slipping or moving back and forth during its up-and-down movement. The cleaning component can improve the integrity of the surface of the LCD housing 1 and prevent dust from accumulating on the surface of the LCD housing 1. When the display screen 2 is not being cleaned, the cleaning component can lift and support the LCD housing 1.

[0027] like Figures 1-4As shown, a limiting component is provided inside the LCD display housing 1. The limiting component consists of a handle 11, a return spring 13, and a U-shaped fixing frame 14. The handle 11 is fixedly installed on the top surface of the mounting plate 6. A through groove adapted to the handle 11 is provided on the bottom surface of the LCD display housing 1. The handle 11 passes through the through groove into the sliding groove 12 and is slidably connected to the LCD display housing 1. A U-shaped fixing frame 14 and symmetrical return springs 13 are fixedly installed on the back of the storage box 3. The other end of the return spring 13 is fixedly connected to the inner wall of the sliding groove 12. A limiting groove is provided on the inner side of the U-shaped fixing frame 14. The handle 11 passes through the limiting groove into the U-shaped fixing frame 14 and moves inward. Press the storage box 3 so that it is fully inserted into the slide groove 12. The return spring 13 is compressed. When the storage box 3 is just fully inserted into the slide groove 12, the compression of the return spring 13 reaches its maximum. At this time, the through groove is aligned with the limiting groove. Install the cleaning component to the bottom of the LCD display housing 1. Move the handle 11 upwards along the through groove so that the handle 11 passes through the LCD display housing 1 and the U-shaped fixing frame 14, thereby limiting and fixing the position of the storage box 3 and preventing the storage box 3 from shaking back and forth. When the cleaning component is removed to clean the display screen 2, the return spring 13 pushes the storage box 3 outwards so that the storage box 3 can catch and collect the dust swept up by the cleaning component.

[0028] Specific working principle:

[0029] When the device needs to clean the front surface of the display screen 2, remove the mounting plate 6 and move it above the LCD housing 1. Align the rollers 9 with the left and right sides of the LCD housing 1 and move the mounting plate 6 downwards. This allows the rollers 9 to contact the left and right sides of the LCD housing 1 and roll downwards along the left and right sides of the LCD housing 1. At the same time, the brush 7 moves downwards close to the display screen 2. Moving the mounting plate 6 up and down can drive the brush 7 to move up and down, thereby cleaning the surface of the display screen 2. The cleaning components can improve the integration of the surface of the LCD housing 1 and prevent dust from accumulating on the surface of the LCD housing 1. The return spring 13 pushes the storage box 3 outwards, which can collect and pick up the dust swept by the cleaning components. Controlling the electric fan 4 to blow air outwards can drive the airflow inside the LCD housing 1. The airflow accelerates the evaporation of water vapor inside the LCD housing 1 and prevents water vapor from accumulating inside the LCD housing 1 and causing wear on the circuit.

[0030] When the device finishes cleaning the display screen 2, it removes the dust from inside the storage box 3 and cleans the storage box 3. It presses the storage box 3 inward so that the storage box 3 is fully inserted into the slide groove 12. The return spring 13 is compressed. When the storage box 3 is just fully inserted into the slide groove 12, the compression of the return spring 13 reaches its maximum. At this time, the through groove is aligned with the limiting groove. The cleaning component is installed at the bottom of the LCD display housing 1. The handle 11 is aligned with the through groove and moved upward so that the handle 11 can pass through the LCD display housing 1 and the U-shaped fixing frame 14, thereby limiting and fixing the position of the storage box 3 and preventing the storage box 3 from shaking back and forth. The cleaning component can lift and support the LCD display housing 1. The support plate 8 and the fixing plate 10 can support the LCD display housing 1 and improve the stability of the LCD display housing 1.
