Description

Technical Field

[0001] The present invention relates to the technical field of displays, and in particular to a digital home intelligent terminal device with a dust-proof function. Background Art

[0002] A digital home intelligent terminal device is a display technology made of semiconductor materials, used to display images, texts, and other visual information in electronic devices. Semiconductor displays usually use solid-state semiconductor materials as the basis for light emission or electrochromism. Among them, the two most common semiconductor display technologies are liquid crystal displays and organic light-emitting diode displays.

[0003] The patent with the application number CN202121923088.6 relates to a semiconductor display with a dust-proof function, including a display body. The top of the right side of the display body is fixedly connected with a heat dissipation component, and the bottoms of the front and rear ends of the display body are both fixedly connected with dust-proof components. The bottom of the right side of the display body is fixedly connected with a bracket; the heat dissipation component includes a mounting ring fixedly connected to the right side of the display body. A heat collection cylinder is fixedly connected to the inner side of the mounting ring. A plurality of heat dissipation fins are fixedly connected to the outer surface of the heat collection cylinder. A heat dissipation fan is fixedly connected to the right end inside the heat collection cylinder. Water tanks are fixedly connected to both the upper and lower ends of the heat collection cylinder. For this digital home intelligent terminal device with a dust-proof function, by setting a heat dissipation component on the display body and adopting the methods of air cooling and external circulation of the coolant to dissipate heat, the heat dissipation effect is effectively improved, ensuring the normal operation of the display body. However, after a large amount of dust accumulates on the dust-proof component of this device, it is easy to cause the decline of the heat dissipation ventilation effect, thereby affecting the heat dissipation effect of the display. Therefore, a digital home intelligent terminal device with a dust-proof function is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a digital home intelligent terminal device with a dust-proof function for the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a digital home intelligent terminal device with a dust-proof function, including a box body and a mounting plate. A display screen is fixedly installed at the front of the box body. A fixing plate is fixedly connected to the bottom of the mounting plate. A sliding groove is formed at the top of the mounting plate. A fixing block is fixedly connected to the rear of the box body. A support plate is fixedly connected to the rear of the box body. A roller is rotatably connected to the inner wall of the rear part of the support plate. Electronic components and a blower with an air flow direction from bottom to top are installed inside the box body. Filter plates are fixedly connected to the inner walls of the top and bottom of the box body. A motor is fixedly connected to the inner wall of the box body. The output end of the motor is fixedly connected to a reciprocating lead screw. A moving plate is movably connected to the surface of the reciprocating lead screw. A pulley is rotatably connected to the inner wall of the moving plate. A cam is fixedly connected to the axis of the pulley. The two sides of the moving plate are rotatably connected to a rotating rod through a torsion spring. A swinging device for improving the heat dissipation effect inside the box body is arranged on the inner wall of the box body. A moisture-proof device for keeping the inside of the box body dry is arranged at the bottom of the box body; the swinging device includes a heat conducting plate, a fan group, an air inlet frame and a push rod. The heat conducting plate is installed on the inner wall of the box body. The fan group is movably connected to the side of the heat conducting plate away from the box body. The air inlet frame is fixedly communicated with the lower surface of the fan group. The push rod is fixedly connected to the lower surface of the air inlet frame; the moisture-proof device includes a telescopic rod and a transmission shaft. The transmission shaft is fixedly connected to the axis of the fan group. The telescopic rod is fixedly connected to the end of the transmission shaft away from the fan group; the inner wall of the sliding groove is in contact with the surface of the fixing block. The surface of the roller is in contact with the front of the fixing plate. The bottom of the moving plate is in contact with the top of the filter plate and the inner wall of the box body respectively. The surface of the pulley is in contact with the top of the filter plate. The side of the cam away from the pulley is in contact with the inner wall of the moving plate. The surface of the rotating rod is in contact with the surface of the rotated cam. Fix the mounting plate on the wall with screws, and then place the fixing block in the sliding groove at the top of the mounting plate. At this time, the support plate on the box body supports on the fixing plate through the roller. At this time, the position of the display can be adjusted left and right for convenient use. At this time, the movement of the box body drives the fixing block to move in the sliding groove, and the support plate drives the roller to roll on the fixing plate and support the box body and the display screen. Moreover, this connection method is convenient for removing the display for maintenance. At the same time, the blower sucks the outside air at the bottom of the box body into the box body and cools and dissipates heat from the display screen. However, dust will also accumulate on the filter plate at the air inlet. At this time, the motor will start intermittently and drive the reciprocating lead screw to rotate. The reciprocating lead screw drives the moving plate to move through the cross-shaped spiral groove and the block in the moving plate. The moving plate drives the pulley to move on the filter plate. At the same time, the pulley itself will rotate and drive the cam to rotate. The cam pushes the rotating rod to rotate. After the cam continues to rotate, the rotating rod will reset through the torsion spring and impact on the filter plate. At this time, the vibration of the filter plate will cause the dust accumulated at the bottom to fall off.

[0006] Preferably, the swinging device further includes a clamping plate, an arc-shaped groove, a magnet I, and a magnet II. The clamping plate is rotatably connected to the inner wall of the heat-conducting plate. The arc-shaped groove is formed on the side of the fan group away from the heat-conducting plate. The magnet I is fixedly connected to the inner wall of the air inlet frame, and the magnet II is fixedly connected to the inner wall of the heat-conducting plate, and the magnet II and the magnet I attract each other magnetically. The side of the clamping plate away from the heat-conducting plate is in contact with the inner wall of the arc-shaped groove. The front part of the air inlet frame is in contact with the rear part of the heat-conducting plate. The surface of the bottom of the push rod is in contact with the surface of the moving rear moving plate. When the backlight generates heat during the use of the display, the heat will be conducted into the heat-conducting plate, and under the action of the fan group, the heat absorbed by the heat-conducting plate will be blown upward and out of the display, which can further improve the heat dissipation effect of the display. When the moving plate moves, it pushes the push rod to move. The push rod drives the fan group to rotate on the heat-conducting plate through the air inlet frame. The magnet II in the air inlet frame moves together, so that one side of the magnet II contacts the other magnet I on the heat-conducting plate and the two attract each other, which can prevent the fan group from automatically rotating and resetting. At this time, the arc-shaped groove on the fan group will move together, and the clamping plate will displace in the arc-shaped groove, so that the clamping plate can fix the fan group on the heat-conducting plate without affecting the rotation of the fan group. The swinging of the fan group can increase the air inlet area of the box body and ensure that the dust is relatively evenly distributed at the bottom of the filter plate.

[0007] Preferably, the moisture-proof device further includes a filter box, a sliding plate, a mounting block, a transmission roller, a brush roller, a transmission plate, and a scraping rod. The filter box is installed at the bottom of the box body. The sliding plate is slidably connected to the inner wall of the filter box. The mounting block is fixedly connected to the bottom of the sliding plate. The transmission roller is rotatably connected to the surface of the mounting block. The brush roller is fixedly connected to the axis of the transmission roller. The transmission plate is fixedly connected to the bottom of the sliding plate. The scraping rod is fixedly connected to the top and bottom of the transmission plate. The surface of the transmission roller is in contact with the inner wall of the filter box. The surface of the transmission shaft is rotatably connected to the inner wall of the box body. The front part of the telescopic rod is in contact with the rear part of the box body. The inner wall of the end of the telescopic rod away from the transmission shaft is rotatably connected to the rear part of the sliding plate through a connecting rod. The air entering the box body will first enter the filter box, and the desiccant in the filter box will absorb the moisture in the air to prevent the display from being affected in service life when working in some humid environments. When the fan group swings, it drives the telescopic rod to swing. The telescopic rod drives the sliding plate to reciprocate in the filter box through the connecting rod. The sliding plate drives the mounting block to move. The mounting block drives the transmission roller to move in the filter box and rotate itself. The transmission roller drives the brush roller to rotate. The brush roller will turn the desiccant in the filter box while the sliding plate moves, increasing the contact area between the desiccant and the air and improving the drying effect and efficiency. When the sliding plate moves, it will also drive the transmission plate to move. The transmission plate drives the scraping rod to move, and the scraping rod further turns the desiccant.

[0008] The present invention adopts the above technical solutions and can bring the following beneficial effects: 1. The digital home intelligent terminal device with dust-proof function can adjust the left and right position of the display through the cooperation of the box body, display screen, mounting plate, fixing plate, sliding groove, fixing block, support plate, roller, electronic components, fan, filter plate, motor, reciprocating lead screw, moving plate, pulley, cam, and rotating rod, which is convenient for use. At this time, the movement of the box body drives the fixing block to move in the sliding groove, and the support plate drives the roller to roll on the fixing plate to support the box body and the display screen. This connection method is convenient for removing the display for maintenance. At the same time, the rotating rod will hit the filter plate, and the vibration of the filter plate will cause the dust accumulated at the bottom to fall, preventing dust accumulation from blocking the ventilation effect during heat dissipation.

[0009] 2. The digital home intelligent terminal device with dust-proof function can further improve the heat dissipation effect of the display through the cooperation of the heat conduction plate, fan group, card plate, arc groove, air inlet frame, push rod, magnet one, and magnet two. The fan group will also swing together during the movement of the moving plate, increasing the air inlet area of the box body during the swinging process of the fan group, ensuring that the dust is relatively evenly distributed at the bottom of the filter plate, facilitating vibration and falling, and preventing excessive dust accumulation in the middle of the filter plate, making it difficult to shake off.

[0010] 3. The digital home intelligent terminal device with dust-proof function can absorb the moisture in the air through the cooperation of the filter box, sliding plate, mounting block, transmission roller, brush roller, telescopic rod, transmission shaft, transmission plate, and scraping rod. The desiccant in the filter box can prevent the display from being affected by its service life when working in some humid environments. The brush roller will turn the desiccant in the filter box while the sliding plate moves, increasing the contact area between the desiccant and the air and improving the drying effect and efficiency. At the same time, the transmission plate drives the scraping rod to move, and the scraping rod further turns the desiccant, thereby ensuring the repeated absorption of moisture in the air, preventing the contact between humid air and dust, and thus preventing the dust from adhering more firmly to the filter box.

Detailed implementation manners

[0013] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0014] Please refer to Figures 1-8, an embodiment of the present invention is: a digital home intelligent terminal device with a dust-proof function, including a box body 1 and a mounting plate 3. A display screen 2 is fixedly installed at the front of the box body 1. A fixing plate 4 is fixedly connected to the bottom of the mounting plate 3. A sliding groove 7 is formed at the top of the mounting plate 3. A fixing block 8 is fixedly connected to the rear of the box body 1. A support plate 9 is fixedly connected to the rear of the box body 1. A roller 10 is rotatably connected to the inner wall at the rear of the support plate 9. Electronic components 11 and a blower 12 with an air flow direction from bottom to top are installed inside the box body 1. Filter plates 13 are fixedly connected to the inner walls at the top and bottom of the box body 1. A motor 14 is fixedly connected to the inner wall of the box body 1. The output end of the motor 14 is fixedly connected to a reciprocating lead screw 15. A moving plate 16 is movably connected to the surface of the reciprocating lead screw 15. A pulley 17 is rotatably connected to the inner wall of the moving plate 16. A cam 18 is fixedly connected to the axis of the pulley 17. Rotating rods 19 are rotatably connected to both sides of the moving plate 16 through torsion springs. A swinging device 5 for improving the heat dissipation effect inside the box body 1 is provided on the inner wall of the box body 1. A moisture-proof device 6 for keeping the inside of the box body 1 dry is provided at the bottom of the box body 1. The display can be moved and adjusted left and right, which is convenient for use. At this time, the movement of the box body 1 drives the fixing block 8 to move in the sliding groove 7, and the support plate 9 drives the roller 10 to roll on the fixing plate 4 to support the box body 1 and the display screen 2. And this connection method is convenient for removing the display for easy maintenance. At the same time, the blower 12 sucks the outside air at the bottom of the box body 1 into the box body 1 to cool and dissipate heat from the display. The swinging device 5 includes a heat conduction plate 51, a fan group 52, an air inlet frame 55 and a push rod 551. The heat conduction plate 51 is installed on the inner wall of the box body 1. The fan group 52 is movably connected to the side of the heat conduction plate 51 away from the box body 1. The air inlet frame 55 is fixedly communicated with the lower surface of the fan group 52. The push rod 551 is fixedly connected to the lower surface of the air inlet frame 55. The moisture-proof device 6 includes a telescopic rod 651 and a transmission shaft 652. The transmission shaft 652 is fixedly connected to the axis of the fan group 52. The telescopic rod 651 is fixedly connected to the end of the transmission shaft 652 away from the fan group 52. The inner wall of the sliding groove 7 is in contact with the surface of the fixing block 8. The surface of the roller 10 is in contact with the front of the fixing plate 4. The bottom of the moving plate 16 is in contact with the top of the filter plate 13 and the inner wall of the box body 1 respectively. The surface of the pulley 17 is in contact with the top of the filter plate 13. The side of the cam 18 away from the pulley 17 is in contact with the inner wall of the moving plate 16. The surface of the rotating rod 19 is in contact with the surface of the rotated cam 18. The rotating rod 19 will reset through the torsion spring and hit the filter plate 13 after the cam 18 continues to rotate. At this time, the vibration of the filter plate 13 will cause the dust accumulated at the bottom to fall off, preventing dust accumulation from blocking the ventilation effect during heat dissipation.

[0015] The swing device 5 further includes a clamping plate 53, an arc-shaped groove 54, a first magnet 552 and a second magnet 553. The clamping plate 53 is rotatably connected to the inner wall of the heat conduction plate 51. The arc-shaped groove 54 is opened on the side of the fan group 52 away from the heat conduction plate 51. The first magnet 552 is fixedly connected to the inner wall of the air inlet frame 55, and the second magnet 553 is fixedly connected to the inner wall of the heat conduction plate 51. The second magnet 553 and the first magnet 552 attract each other magnetically. Under the action of the fan group 52, the heat absorbed by the heat conduction plate 51 is blown upward and out of the display, which can further improve the heat dissipation effect of the display. The side of the clamping plate 53 away from the heat conduction plate 51 is in contact with the inner wall of the arc-shaped groove 54. The front part of the air inlet frame 55 is in contact with the rear part of the heat conduction plate 51. The surface of the bottom of the push rod 551 is in contact with the surface of the moving plate 16 after moving. The swing of the fan group 52 can increase the air inlet area of the box body 1, ensure that the dust is relatively evenly distributed at the bottom of the filter plate 13, facilitate vibration and dropping, and prevent excessive dust accumulation in the middle of the filter plate 13, making it difficult to shake off.

[0016] Working principle: Fix the mounting plate 3 on the wall with screws. Then place the fixing block 8 in the sliding groove 7 at the top of the mounting plate 3. At this time, the support plate 9 on the box body 1 is supported on the fixing plate 4 by the rollers 10. At this time, the left and right position adjustment of the display can be carried out, which is convenient for use. At this time, the movement of the box body 1 drives the fixing block 8 to move in the sliding groove 7, and the support plate 9 drives the rollers 10 to roll on the fixing plate 4 to support the box body 1 and the display screen 2. And this connection method is convenient for removing the display for maintenance. At the same time, the fan 12 sucks the outside air at the bottom of the box body 1 into the box body 1 to cool and dissipate heat from the display, but dust will also accumulate on the filter plate 13 at the air inlet. At this time, the motor 14 will start intermittently and drive the reciprocating lead screw 15 to rotate. The reciprocating lead screw 15 drives the moving plate 16 to move through the cross-shaped spiral groove and the block in the moving plate 16. The moving plate 16 drives the pulley 17 to move on the filter plate 13. At the same time, the pulley 17 itself will rotate and drive the cam 18 to rotate. The cam 18 pushes the rotating rod 19 to rotate. After the cam 18 continues to rotate, the rotating rod 19 will reset through the torsion spring and hit the filter plate 13. At this time, the vibration of the filter plate 13 will cause the dust accumulated at the bottom to fall off, preventing dust accumulation from blocking the ventilation effect during heat dissipation.

[0017] When the display is in use, the backlight will generate heat. At this time, the heat will be conducted to the heat conduction plate 51, and under the action of the fan group 52, the heat absorbed by the heat conduction plate 51 will be blown upward and out of the display, which can further improve the heat dissipation effect of the display. When the moving plate 16 moves, it pushes the push rod 551 to move. The push rod 551 drives the fan group 52 to rotate on the heat conduction plate 51 through the air inlet frame 55. The magnet two 553 in the air inlet frame 55 moves together, so that one side of the magnet two 553 contacts the other magnet one 552 on the heat conduction plate 51 and the two attract each other, which can prevent the fan group 52 from automatically rotating and resetting. At this time, the arc-shaped groove 54 on the fan group 52 will move together, and the clamping plate 53 will displace in the arc-shaped groove 54, so that the clamping plate 53 can fix the fan group 52 on the heat conduction plate 51 without affecting the rotation of the fan group 52. The swing of the fan group 52 can increase the air inlet area of the box body 1, ensure that the dust is relatively evenly distributed at the bottom of the filter plate 13, facilitate vibration and falling, and prevent too much dust from accumulating in the middle of the filter plate 13 and being difficult to shake off.

[0018] Please refer to Figures 9-11 , on the basis of the above embodiments, in another embodiment of the present invention, the moisture-proof device 6 further includes a filter box 61, a sliding plate 62, a mounting block 63, a transmission roller 64, a brush roller 65, a transmission plate 653 and a scraping rod 654. The filter box 61 is installed at the bottom of the box body 1. The sliding plate 62 is slidably connected to the inner wall of the filter box 61, and the mounting block 63 is fixedly connected to the bottom of the sliding plate 62; the transmission roller 64 is rotatably connected to the surface of the mounting block 63, the brush roller 65 is fixedly connected to the axis of the transmission roller 64, the transmission plate 653 is fixedly connected to the bottom of the sliding plate 62, and the scraping rod 654 is fixedly connected to the top and bottom of the transmission plate 653. The brush roller 65 will turn the desiccant in the filter box 61 while the sliding plate 62 moves, increasing the contact area between the desiccant and the air and improving the drying effect and efficiency; the surface of the transmission roller 64 is in contact with the inner wall of the filter box 61, the surface of the transmission shaft 652 is rotatably connected to the inner wall of the box body 1, the front part of the telescopic rod 651 is in contact with the rear part of the box body 1, and the inner wall of the end of the telescopic rod 651 away from the transmission shaft 652 is rotatably connected to the rear part of the sliding plate 62 through a connecting rod, so as to ensure the repeated absorption of moisture in the air, prevent the contact between the moist air and the dust, and further prevent the dust from adhering more firmly to the filter box 61.

[0019] Working principle: The air entering the box body 1 will first enter the filter box 61, and the desiccant in the filter box 61 will absorb the moisture in the air to prevent the display from working in some humid environments and affecting its service life. When the fan group 52 swings, it drives the telescopic rod 651 to swing. The telescopic rod 651 drives the slide plate 62 to reciprocate in the filter box 61 through a connecting rod. The slide plate 62 drives the mounting block 63 to move, and the mounting block 63 drives the transmission roller 64 to move in the filter box 61 and rotate itself. The transmission roller 64 drives the brush roller 65 to rotate. The brush roller 65 will turn the desiccant in the filter box 61 while the slide plate 62 moves, improving the contact area between the desiccant and the air and enhancing the drying effect and efficiency. When the slide plate 62 moves, it will also drive the transmission plate 653 to move, and the transmission plate 653 drives the scraping rod 654 to move. The scraping rod 654 further turns the desiccant, so as to ensure the repeated absorption of moisture in the air, prevent the humid air from contacting the dust, and thus prevent the dust from adhering more firmly to the filter box 61.
