Description

Technical Field

[0001] The present application relates to the technical field of LED display screens, and in particular to an LED display screen assembly. Background Art

[0002] LED display is a display technology that uses light-emitting diodes (LEDs) as light sources. It is a flat display device that is widely used in televisions, computer monitors, billboards, outdoor advertising screens, sports stadium displays, and many other applications.

[0003] Some large LED screens use fans for ventilation and heat dissipation. Although this heat dissipation method has a higher heat dissipation efficiency than heat sinks, when used in a humid environment, the fan is more likely to bring a large amount of humid air into the LED screen, thereby corroding its internal components and affecting the normal use of electronic components. Utility Model Content

[0004] In view of this, the purpose of the present invention is to solve the shortcomings of the background technology and to propose an LED display screen assembly to solve the problems existing in the prior art.

[0005] To achieve the above purpose, the utility model provides an LED display screen assembly, including a display screen body, a filter frame is provided on the outer surface of the display screen body, a two-way fan is fixedly installed inside the filter frame, a drying box is provided inside the display screen body, desiccant particles are provided inside the drying box, an anti-seepage net is provided on the inner wall of the drying box, a plurality of air exchange holes are provided on the outer surface of the drying box, a driving mechanism for stirring the desiccant particles is provided inside the display screen body, and the airflow for ventilation and heat dissipation of the two-way fan can enter the drying box through the air exchange holes.

[0006] Preferably, the driving mechanism comprises a driving box fixedly connected to the outer surface of the drying box, and a motor is fixedly installed on the top of the driving box. The driving mechanism can drive the rotating shaft to rotate, thereby allowing the stirring blades to continuously stir the desiccant particles.

[0007] Preferably, a worm is rotatably connected to the inner surface of the drive box, and the top of the worm is fixedly connected to the output end of the motor.

[0008] Preferably, the inner surface of the drive box is rotatably connected with a rotating shaft, the outer surface of the rotating shaft is fixedly sleeved with a worm gear, and the outer surface of the worm gear is meshingly connected with the outer surface of the worm.

[0009] Preferably, the outer surface of the rotating shaft is provided with a plurality of groups of stirring blades.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. In the LED display assembly, the airflow is sucked into the drying box. The driving mechanism allows the stirring blades to continuously stir the desiccant particles in the drying box. The desiccant particles will continuously change their positions, so that the moist airflow can more fully contact the surface of the desiccant, increasing the contact area between the two, making the desiccant particles more fully in contact with the moist airflow, and the moisture in the moist airflow is more easily adsorbed and removed by the desiccant, thereby effectively reducing the erosion of the electronic components inside the display body.

[0012] 2. The LED display assembly uses a two-way fan for ventilation and heat dissipation. The two-way fan can absorb airflow and release the hot airflow inside the display. In the process of ventilation and heat dissipation in a relatively humid environment, the filter frame can block external dust and other impurities to a certain extent, ensuring that the airflow entering the LED display has a high degree of cleanliness.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] See also Figure 1-4A LED display assembly comprises a display body 1, a filter frame 2 is arranged on the outer surface of the display body 1, a two-way fan 3 is fixedly installed inside the filter frame 2, a drying box 10 is arranged inside the display body 1, desiccant particles 11 are arranged inside the drying box 10, an anti-seepage net 12 is arranged on the inner wall of the drying box 10, a plurality of air exchange holes 13 are opened on the outer surface of the drying box 10, and a driving mechanism for stirring the desiccant particles 11 is arranged inside the display body 1.

[0020] Through the above technical solution, the LED display screen ventilates and dissipates heat inside the display screen body 1 through the two-way fan 3 during use, and the stirring blades 9 can continuously stir the desiccant particles 11 under the action of the driving mechanism, thereby increasing the contact area between the desiccant particles 11 and the humid airflow, reducing the moisture contained in the airflow, and reducing the erosion of electronic components.

[0021] Specifically, the driving mechanism includes a driving box 4 fixedly connected to the outer surface of the drying box 10 , and a motor 5 is fixedly installed on the top of the driving box 4 .

[0022] Through the above technical solution, the worm 6 can be driven by the motor 5 to rotate, thereby driving the worm wheel 7 meshing with it to rotate.

[0023] Specifically, the inner surface of the driving box 4 is rotatably connected with a worm 6 , and the top of the worm 6 is fixedly connected to the output end of the motor 5 .

[0024] Through the above technical solution, the tooth grooves on the surface of the worm 6 and the teeth on the surface of the worm wheel 7 are just matched, so the two can transmit during the meshing connection process.

[0025] Specifically, the inner surface of the driving box 4 is rotatably connected with a rotating shaft 8 , the outer surface of the rotating shaft 8 is fixedly sleeved with a worm gear 7 , and the outer surface of the worm gear 7 is meshingly connected with the outer surface of the worm 6 .

[0026] Through the above technical solution, one end of the rotating shaft 8 is located in the driving box 4 , and the other end is located in the drying box 10 .

[0027] Specifically, a plurality of groups of stirring blades 9 are arranged on the outer surface of the rotating shaft 8 .

[0028] Through the above technical solution, the stirring blades 9 evenly arranged on the surface of the rotating shaft 8 can effectively stir the desiccant particles 11 in the drying box 10 continuously.

[0029] Working principle: When the LED display screen is in use, the display screen body 1 is ventilated and cooled by the two-way fan 3. The two-way fan 3 can absorb airflow and release the hot airflow inside the display screen. In the process of ventilation and heat dissipation in a relatively humid environment, the filter frame 2 can block external dust and other impurities to a certain extent, ensuring that the airflow entering the LED display screen has a high degree of cleanliness. The humid airflow will contain more moisture. In the process of entering the drying box 10 through the air exchange hole 13, the motor 5 can be turned on to drive the worm 6 to rotate, and then the worm gear 7 is linked to rotate. The worm gear 7 will make the rotating shaft 8 rotate synchronously during the rotation process. The part of the rotating shaft 8 in the drying box 10 is provided with a plurality of groups of stirring blades 9 on its surface. The stirring blades 9 will continuously stir the desiccant particles 11 in the drying box 10. The desiccant is usually a porous material or a material with a large surface area, such as silica gel or molecular sieve. Through the continuous stirring of the stirring blades 9, the desiccant particles 11 will continuously change their positions, so that the humid airflow can more fully contact the surface of the desiccant. , thereby increasing the contact area between the two, and the adsorption force on the surface of the desiccant particles 11 enables it to adsorb water molecules. By increasing the contact area, the desiccant particles 11 are in more complete contact with the humid airflow, making it easier for the water molecules to be adsorbed by the desiccant, so that the moisture in the humid airflow can be removed more effectively. When the humid airflow passes through the desiccant particles 11, the water molecules therein will be adsorbed onto the surface of the desiccant. By continuously stirring the desiccant particles 11, the desiccant particles 11 that have already adsorbed moisture can be exposed to the airflow again, thereby continuing to adsorb more water molecules, further reducing the moisture content in the airflow, and finally allowing the airflow with very little water content to be discharged from the drying box 10 through the air exchange holes 13 again, thereby effectively ventilating and cooling the LED display screen, while greatly reducing the erosion of the electronic components inside the display screen body 1, extending its service life, and improving the stability and reliability of the equipment. The purpose of the anti-seepage net 12 is to prevent the desiccant particles 11 from being discharged from the air exchange holes 13 along with the airflow, thereby playing a blocking and intercepting effect.

[0030] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
