[0018] 2. When the air enters the air outlet part along the air pipe in the present invention, it will first gather in the air outlet part. During the gathering process, the pressure continuously increases, driving the sealing plate to move and compress the second spring. When the sealing plate does not contact the inner wall of the air outlet part, the air will be evenly ejected along the air outlet, thereby improving the blowing effect on the dust and fog and further avoiding the influence of dust and fog on the display screen.

At this time, the sliding frame is pulled to make the sponge block wipe on the display screen, wiping off the small amount of dust and impurities to improve the display effect of the display screen. At the same time, the air flow blown out from the air outlet will enter the communication cavity and blow out along the inclined air holes to cooperate with the wiping block to clean the display screen, further reducing the influence of dust on the display screen. At the same time, after the air flow blown out from the inclined air holes contacts the display screen, it will change direction and further disperse the dust and fog around the display screen, facilitating the use of the display screen.

[0022] Reference will now be made to example embodiments to discuss the subject matter described herein. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example may omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0023] As Figures 1 to 4 shown, a high-definition display device for an infrared thermal imager according to an embodiment of the present invention, the high-definition display device for an external thermal imager is used to detect the temperature change of equipment in real time through the infrared thermal imager main body 14 in an industrial production environment affected by soot and dust, and monitor the real-time display of the image through the display screen 11. It includes a housing 10, the infrared thermal imager main body 14 is fixedly installed on the housing 10, and the display screen 11 is arranged in the housing 10 through a connection component; A holding component 30 is arranged on the housing 10. The holding component 30 includes an installation cavity 31 opened on the housing 10. A motor 32 is fixedly installed in the installation cavity 31. A blade 33 is fixedly installed on the output shaft of the motor 32. An air pipe 34 communicated with the installation cavity 31 is fixedly installed on the housing 10. One end of the air pipe 34 away from the installation cavity 31 is fixed with an air outlet member 35 arranged in a rectangular shape. An air outlet 36 is opened on the air outlet member 35. A synchronization component 40 is cooperatively arranged on the air outlet member 35. Under the action of the synchronization component 40, the air flow accumulates pressure in the air outlet member 35 first, and then sprays out along the air outlet 36, adapts to the outer periphery of the display screen 11 and diffuses evenly outwards; In some industrial production environments, such as petrochemical plants and steel plants, the normal operation of equipment is crucial. Infrared thermal imagers can penetrate dust and fog, detect the temperature change of equipment, and timely discover potential fault hazards to ensure the continuity and safety of production. However, the industrial production environment is usually accompanied by diffuse dust and fog, which will affect the presentation of the infrared thermal imaging results of the display screen 11. When the present invention is used in an industrial production environment, the motor 32 is started to drive the blade 33 to rotate. When the blade 33 rotates, it drives the air flow to enter the installation cavity 31 and enter the air outlet member 35 along the air pipe 34 and spray out along the air outlet 36. Due to the existence of the filter screen 37, when the air is inhaled into the installation cavity 31, the dust and fog in the air are blocked by the filter screen 37 together. The blown pure air flow blows away the dust and fog in the air near the display screen 11. On the one hand, it reduces the attachment of dust and fog on the display screen 11 and affects the display effect, and maintains the normal display effect of the display screen 11. On the other hand, it can blow away the dust and fog between the display screen 11 and the staff, which can make it more convenient for the staff to observe the display screen 11.

[0024] As Figure 5 shown, the synchronization component 40 includes a vertical plate 41 fixedly installed in the air outlet member 35. A positioning rod 42 is fixedly installed on the vertical plate 41. A sealing plate 44 that cooperates with the rectangular air outlet member 35 is slidably installed on the positioning rod 42. A second spring 43 is fixedly installed on the sealing plate 44. One end of the second spring 43 away from the sealing plate 44 is fixedly connected to the vertical plate 41; When air enters the air outlet member 35 along the air pipe 34, it will first gather in the air outlet member 35. During the gathering process, the pressure continuously increases, driving the sealing plate 44 to move and compress the second spring 43. When the sealing plate 44 does not contact the inner wall of the air outlet member 35, the air will uniformly spray out along the air outlet 36, thereby improving the blowing effect on dust and fog, and further avoiding the influence of dust and fog on the display screen 11.

[0025] As Figure 6 shown, the wiping component 50 is installed on the holding component 30 and is disposed in the air outlet 36 for wiping and cleaning the display surface of the display screen 11. The wiping component 50 includes a sliding frame 51 slidably installed in the air outlet 36. A sponge block is disposed on the side of the sliding frame 51 facing the display. The wiping component 50 further includes a communication cavity 52 opened in the sliding frame 51 and communicating with the air outlet 36. A plurality of inclined air holes 53 communicating with the communication cavity 52 are opened on the sliding frame 51; After the device has been used for a period of time, a small amount of dust and impurities will adhere to the display screen 11, affecting the display effect. At this time, the sliding frame 51 is pulled to wipe the sponge block on the display screen 11 to wipe off a small amount of dust and impurities, thereby improving the display effect of the display screen 11. At the same time, the air flow blown out from the air outlet 36 will enter the communication cavity 52 and blow out along the inclined air holes 53 to cooperate with the wiping block to clean the display screen 11, further reducing the influence of dust on the display screen 11. At the same time, after the air flow blown out from the inclined air holes 53 contacts the display screen 11, it will change direction and further blow away the dust and fog around the display screen 11, facilitating the use of the display screen 11.

[0026] As Figure 6 shown, a protection component 60 that cooperates with the inclined air holes 53 is disposed on the upper surface of the sliding frame 51. The protection component 60 includes a mounting sleeve 61 fixedly installed on the sliding frame 51. A sliding rod 62 is slidably installed in the mounting sleeve 61. A third spring 64 is fixedly installed on the sliding rod 62. One end of the third spring 64 away from the sliding rod 62 is fixedly connected to the inner wall of the mounting sleeve 61. A retaining piece 63 is fixedly installed at the end of the sliding rod 62 away from the third spring 64. The retaining piece 63 is adapted to the inclined air holes 53; To prevent dust and impurities from falling into the communication cavity 52 along the inclined air holes 53, when air flows out of the inclined air holes 53, the air flow contacts the baffle 63 and causes the sliding rod 62 to move and compress the third spring 64. At this time, the air flow blows out normally. When the inclined air holes 53 do not emit air, the third spring 64 drives the sliding rod 62 and the baffle 63 to reset and block the upper inclined air holes 53, thus preventing dust from entering the communication holes and affecting the normal flow of air.

[0027] As Figure 3 shown, a cleaning assembly 70 capable of cleaning the filter screen 37 is provided on the output shaft of the motor 32. The cleaning assembly 70 includes an extension shaft 71 fixedly installed on the output shaft of the motor 32. The extension shaft 71 penetrates the filter screen 37 and a cleaning brush 72 is fixedly installed thereon. The cleaning brush 72 contacts the outer side of the filter screen 37; When the motor 32 operates, its output shaft drives the extension shaft 71 to rotate, and the rotation of the extension shaft 71 causes the cleaning brush 72 to wipe the surface of the filter screen 37 and scrape off the blocked dust and impurities, so that the filter screen 37 maintains a good ventilation and filtering effect.

[0028] The connection assembly includes a mounting hole 12 formed in the housing 10. A mounting rod 13 is slidably installed in the mounting hole 12, and the display screen 11 is fixedly installed on the mounting rod 13.

[0029] As Figures 7 to 8 shown, heat is generated during the use of the display screen 11. If the device is used for a long time, the rising temperature will affect the normal display effect of the display screen 11. A protection mechanism 20 for protecting the display screen 11 is provided in the housing 10. The protection mechanism 20 includes a storage cavity 21 formed in the housing 10 for storing coolant. An outflow hose 22 is fixedly installed on the housing 10. A micro water pump for pumping coolant is provided in the storage cavity 21. One end of the outflow hose 22 away from the housing 10 is fixedly installed with a hollow heat conducting tube 23. A first spring 25 is fixedly installed on the hollow heat conducting tube 23. One end of the first spring 25 away from the hollow heat conducting tube 23 is fixedly connected to the inner wall of the housing 10. The hollow heat conducting tube 23 abuts against the display screen 11. An inflow hose 24 is fixedly installed on the hollow heat conducting tube 23. One end of the inflow hose 24 away from the hollow heat conducting tube 23 communicates with the storage cavity 21. A heat conducting plate 26 is fixedly installed in the storage cavity 21, and a part of the heat conducting plate 26 is arranged in the installation cavity 31; When the display screen 11 is in use, the hollow heat-conducting tube 23 will absorb the heat emitted by the display screen 11. The micro water pump will cause the coolant to enter the hollow heat-conducting tube 23 along the outflow hose 22. When the coolant passes through the hollow heat-conducting tube 23, it will absorb the heat on the hollow heat-conducting tube 23 and return to the storage cavity 21 along the inflow hose 24 for heat dissipation. The heat is transferred to the heat-conducting plate 26. When the air flow passes through the installation cavity 31, it will cool the heat-conducting plate 26, thereby achieving the effect of cooling the entire display screen 11.

[0030] Working principle: When the present invention is used in an industrial production environment, the motor 32 is started to drive the blade 33 to rotate. When the blade 33 rotates, it drives the air flow into the installation cavity 31 and enters the air outlet member 35 along the air pipe 34 and is ejected along the air outlet 36. Due to the presence of the filter screen 37, when the air is inhaled into the installation cavity 31, the dust and fog in the air are blocked by the filter screen 37 together. The blown pure air flow blows away the dust and fog in the air near the display screen 11. On the one hand, it reduces the attachment of dust and fog to the display screen 11 and affects the display effect, and maintains the normal display effect of the display screen 11. On the other hand, it can blow away the dust and fog between the display screen 11 and the staff. When the air enters the air outlet member 35 along the air pipe 34, it will first gather in the air outlet member 35. During the gathering process, the pressure continuously increases to drive the sealing plate 44 to move and squeeze the second spring 43. When the sealing plate 44 does not contact the inner wall of the air outlet member 35, the air will be ejected evenly along the air outlet 36, thereby improving the blowing effect on the dust and fog. Pull the sliding frame 51 to wipe the sponge block on the display screen 11 to wipe off a small amount of dust and impurities, so as to improve the display effect of the display screen 11. At the same time, the air flow blown out from the air outlet 36 will enter the communication cavity 52 and blow out along the inclined air holes 53 to cooperate with the wiping block to clean the display screen 11, further reducing the influence of dust on the display screen 11. At the same time, when the air flow blown out from the inclined air holes 53 contacts the display screen 11, it will change direction and further blow away the dust and fog around the display screen 11. When the air flow blows out from the inclined air holes 53, the air flow contacts the baffle 63 and makes the sliding rod 62 move to squeeze the third spring 64. At this time, the air flow blows out normally. When the inclined air holes 53 do not emit air, the third spring 64 drives the sliding rod 62 and the baffle 63 to reset to block the upper inclined air holes 53, thereby preventing dust from entering the communication holes and affecting the normal flow of the air flow. When the motor 32 operates, its output shaft drives the extension shaft 71 to rotate, and the rotation of the extension shaft 71 will cause the cleaning brush 72 to wipe the surface of the filter screen 37 to scrape off the blocked dust and impurities, so that the filter screen 37 maintains a good ventilation and filtering effect. When the display screen 11 is in use, the hollow heat-conducting tube 23 will absorb the heat emitted by the display screen 11. The micro water pump will make the coolant enter the hollow heat-conducting tube 23 along the outflow hose 22. When the coolant passes through the hollow heat-conducting tube 23, it absorbs the heat on the hollow heat-conducting tube 23 and returns to the storage cavity 21 along the inflow hose 24 for heat dissipation. The heat is transferred to the heat-conducting plate 26. When the air flow passes through the installation cavity 31, it will cool the heat-conducting plate 26, thereby achieving the effect of cooling the entire display screen 11.

[0031] The embodiments of the present invention have been described above, but the embodiments are not limited to the above specific implementation manners. The above specific implementation manners are only illustrative and not restrictive. Under the inspiration of the present embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of the present embodiment.
