Display with dustproof structure

Abstract

This invention relates to a display with a dustproof structure. The invention includes a display body, which is fixed to a protective shroud by a first screw. The interior of the protective shroud is hollow, forming an air duct. A first air outlet is formed on the beveled end face of its front edge, and a second air outlet is formed on the top. A fan and a mounting bracket are fixed to the rear of the protective shroud. The fan inlet is connected to a filter box, in which a first filter, a second filter, and a third filter are sequentially installed via a filter mounting bracket. This invention uses a fan to deliver clean air filtered through three layers into the air duct, which is then ejected from the first and second air outlets, forming dustproof air curtains on the front and back of the display, respectively. This solves the problems of incomplete dust protection and difficult maintenance of filter components in existing displays, and has the advantages of compact structure, double air curtain protection, and quick filter replacement, making it suitable for high-dust industrial environments.

Description

Technical Field

[0001] This invention relates to the field of display device technology, specifically to a display with a dustproof structure. Background Technology

[0002] As information output terminals, monitors are widely used in various fields such as industrial control, outdoor advertising, traffic guidance, and daily office work. In high-dust environments such as industrial workshops, construction sites, mining areas, and outdoor transportation hubs, monitors are exposed to a large amount of suspended particulate matter for extended periods. Dust can easily enter the monitor through its heat dissipation vents, bezel gaps, and interface openings.

[0003] To dissipate heat, current monitors have numerous ventilation holes in their casings and rely on internal fans for forced airflow. However, these ventilation holes directly become channels for dust to enter the interior, causing dust to accumulate on the circuit boards, backlight modules, and panel surfaces, affecting heat dissipation efficiency and even causing short circuits or display malfunctions. A few monitors add dust filters to the ventilation holes, but these filters are mostly built-in or fixed structures, making them difficult for users to remove and clean. Over time, the dust filters become clogged, leading to a sharp decrease in heat dissipation capacity and an increased equipment failure rate.

[0004] Therefore, there is an urgent need for a dustproof structure for monitors that can effectively prevent dust intrusion, ensure good heat dissipation, and facilitate maintenance. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention discloses a display with a dustproof structure. The technical solution adopted is that the main body of the display is fixedly connected to the protective shroud by a first screw. The front edge of the protective shroud has a beveled end face, and a first air outlet is formed on the beveled end face. A second air outlet is formed on the top of the protective shroud. The interior of the protective shroud is hollow and forms an air duct. The first and second air outlets are connected to the air duct. A mounting bracket and a fan are fixedly connected to the rear of the protective shroud. The air outlet of the fan is connected to the air duct, and the air inlet is connected to a filter box. A filter element mounting bracket is installed in the filter box. A first filter element, a second filter element, and a third filter element are installed sequentially from the outside to the inside at both ends of the filter element mounting bracket. The first filter element is a coarse filtration layer used to intercept large dust particles and is made of polyester synthetic fiber filter cotton. The second filter element is an electrostatic adsorption layer used to adsorb fine dust particles and is made of electrostatic adsorption filter element. The third filter element is an activated carbon layer used to adsorb corrosive gases and is made of activated carbon fiber felt. Outside air is filtered through three layers before entering the fan, then sent into the air duct, and finally ejected from the first and second air outlets, forming air curtain barriers in front of and behind the main body of the display, effectively protecting the fan and the internal components of the display.

[0006] In a preferred embodiment of the present invention, an internally threaded tube is fixedly connected to the back of the display body, and the first screw is threaded onto the internally threaded tube. The end of the internally threaded tube presses against the protective shroud, creating a gap between the back of the display body and the protective shroud. This gap serves as a channel for airflow at the back, facilitating the exhaust of hot air and forming a back air curtain in conjunction with the second air outlet.

[0007] In a preferred embodiment of the present invention, the first air outlet is located on the front left and right sides and the top of the display body, and the second air outlet is located at the rear upper part of the display body, corresponding to the gap between the back of the display body and the protective air cover. This layout achieves wraparound air curtain protection for the front screen area of ​​the display, as well as directional air curtain protection for the rear heat dissipation area.

[0008] In a preferred embodiment of the present invention, the filter box has air inlets on both its left and right sides, and an opening on its lower surface, with a connecting plate fixedly connected to the edge of the opening. The filter element mounting bracket is fixedly connected to the connecting plate. This lateral air inlet design effectively prevents large particles from falling directly into the filter box.

[0009] In a preferred embodiment of the present invention, the filter element mounting bracket includes a cover plate. Multiple spacer plates are fixedly connected to both ends of the upper surface of the cover plate. Ventilation ports are evenly distributed on the spacer plates. The first, second, and third filter elements are respectively snapped between the spacer plates and inserted into the filter box. The cover plate is fixedly connected to the connecting plate by a second screw. A sealing gasket is provided between the cover plate and the connecting plate to improve the sealing of the connection. This structure achieves a modular, quick-release design for the filter elements, allowing them to be pulled out from the bottom for replacement without disassembling the entire unit. A handle is fixedly connected to the center of the lower surface of the cover plate for easy gripping when disassembling the filter element mounting bracket.

[0010] The beneficial effects of this invention are as follows: By opening a first air outlet at the front edge of the protective shroud and a second air outlet at the top, combined with the gap design on the back of the display, this invention achieves all-round air curtain coverage for the heat dissipation areas of the front and back of the display screen, effectively preventing external dust from contacting the display surface and intruding into internal gaps. The drawer-type filter mounting bracket design allows for quick filter replacement by inserting the filter from the bottom and using the cover and handle, without disassembling the display body or the protective shroud, greatly reducing on-site maintenance difficulty and time costs. The combination of polyester fiber coarse filtration, electrostatic adsorption, and activated carbon fiber felt effectively copes with heavily polluted environments where high concentrations of dust, fine particles, and corrosive gases coexist, extending the lifespan of the display in industrial settings. The connection method of the internally threaded tube and the first screw ensures a predetermined gap between the display body and the protective shroud while guaranteeing the rigidity of the overall structure.

An internally threaded tube 101 is fixedly connected to the back of the display body 1. The first screw 6 is threaded onto the internally threaded tube 101. The end of the internally threaded tube 101 presses against the protective shroud 2, creating a gap between the back of the display body 1 and the protective shroud 2. This gap serves as a channel for airflow from the back, facilitating the exhaust of hot air. The front edge of the protective shroud 2 has a beveled end face 201, and a first air outlet 202 is formed on the beveled end face 201. A second air outlet 203 is formed on the top of the protective shroud 2. The interior of the protective shroud 2 is hollow, forming an air duct 204. The first air outlet 202 and the second air outlet 203 communicate with the air duct 204. The first air outlet 202 is located on the front left and right sides and the top of the display body 1, achieving a wraparound air curtain protection for the front screen area of ​​the display. The second air outlet 203 is located at the upper rear of the display body 1 and corresponds to the gap between the back of the display body 1 and the protective wind shield 2. The second air outlet 203 and the gap form a back air curtain to provide directional air curtain protection for the heat dissipation area on the back of the display body 1.

[0021] The protective hood 2 is fixedly connected to the rear of the mounting bracket 3 and the fan 4. The air outlet of the fan 4 is connected to the air duct 204, and the air inlet is connected to the filter box 5. The filter box 5 has air inlets 501 on the left and right sides, and the lower surface of the filter box 5 is open. A connecting plate 502 is fixedly connected to the edge of the opening. The side air inlet design of the filter box 5 can effectively prevent large particles of debris from falling directly into the filter box 5. The filter box 5 is equipped with a filter element mounting bracket 7. From the outside in, a first filter element 8, a second filter element 9, and a third filter element 10 are sequentially mounted on both ends of the filter element mounting bracket 7. The filter element mounting bracket 7 includes a cover plate 701. Multiple spacer plates 702 are fixedly connected to both ends of the upper surface of the cover plate 701. Vents 7021 are evenly distributed on the spacer plates 702. The first filter element 8, the second filter element 9, and the third filter element 10 are respectively snapped between the spacer plates 702 and inserted into the filter box 5. The cover plate 701 is fixedly connected to the connecting plate 502 by second screws 703. A sealing gasket is provided between the cover plate 701 and the connecting plate 502 to improve the sealing of the connection. This structure achieves a modular quick-release design for the filter elements, allowing them to be pulled out from the bottom for replacement without disassembling the entire machine. A handle 704 is fixedly connected to the center of the lower surface of the cover plate 701 for easy gripping when removing the filter element mounting bracket 7.

[0022] The first filter element 8 is a coarse filtration layer used to intercept large dust particles, and is made of polyester synthetic fiber filter cotton; the second filter element 9 is an electrostatic adsorption layer used to adsorb fine dust particles, and is made of electrostatic adsorption filter element; the third filter element 10 is an activated carbon layer used to adsorb corrosive gases, and is made of activated carbon fiber felt. Outside air enters the filter box 5 through the air inlet 501, and after passing through the three layers of filtration, it enters the fan 4, is then sent into the air duct 204, and is finally ejected from the first air outlet 202 and the second air outlet 203, forming an air curtain barrier in front of and behind the display body 1, respectively, effectively protecting the fan 4 and the internal components of the display from the influence of dust particles and corrosive gases in the air.
