[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] Some embodiments of the present invention are described below in conjunction with the accompanying drawings. Embodiment 1

[0024] Combination Figure 1-5 As shown, this embodiment provides an LED display screen with a dustproof structure, including: a main body module 100.

[0025] Among them, the main module 100 includes a display screen body 110, a connecting tube 120 fixed on the top of the display screen body 110, an air supply pipe 130 symmetrically fixed on one side of the connecting tube 120 and connected to the connecting tube 120, a blowing member 140 symmetrically fixed on one side of the display screen body 110 and connected to the air supply pipe 130, a spray member 150 arranged on one side of the connecting tube 120 and slidably engaged on the display screen body 110 at both ends, and a sponge pad 160 fixed on the side of the spray member 150 close to the display screen body 110 and closely attached to the display screen body 110.

[0026] The display screen body 110 is used to display images, videos and other contents for the convenience of users to understand. The blowing member 140 is fixed on one side of the display screen body 110, including a tube body 141 fixed on the display screen body 110, a silent fan 142 installed on the inner wall of the tube body 141, and a filter 143 fixed on the inner wall of the tube body 141. The tube body 141 is connected with the air supply pipe 130, and the inner bottom wall of the tube body 141 is arranged in an inclined surface, which is convenient for introducing high-speed flow into the air supply pipe 130. The air supply pipe 130 connects the tube body 141 with the connecting pipe 120, which is convenient for high-speed airflow to enter the connecting pipe 120. The silent fan 142 is used to accelerate the air out, and the filter 143 is used to prevent dust from entering.

[0027] The ejection member 150 is connected to the connecting tube 120 and is used to eject high-speed airflow, including a nozzle 151 arranged on one side of the display screen body 110 and with the top end extending into the connecting tube, sliders 152 symmetrically fixed at both ends of the nozzle 151 and slidably engaged on both sides of the display screen body 110, and a pull plate 153 fixed on one side of the slider 152. The nozzle 151 has a trapezoidal cross-section, with the top movably extending into the connecting tube 120 and the bottom parallel to the display screen body 110, and is used to eject high-speed airflow, generating a top-down airflow wall on the screen surface of the display screen body 110, so that dust will fly away under the action of the airflow when it approaches the screen of the display screen body 110, thereby preventing dust from adhering to the screen of the display screen body 110.

[0028] Slide bars 111 are fixed on both sides of the display screen body 110, and a slide groove 1521 is opened on the inner side of the slider 152. The slide bar 111 is engaged with the slide groove 1521 to limit the movement of the slider 152, that is, to limit the movement of the nozzle 151. The sponge pad 160 is fixed on the inner side of the nozzle 151 and is closely attached to the surface of the display screen body 110. When the user moves the pull plate 153, the nozzle 151 is moved by the slide bar 152, and the movement of the nozzle 151 drives the sponge pad 160 to move on the surface of the display screen body 110, so that the dust and impurities attached to the surface of the display screen body 110 are scraped off, thereby cleaning the surface of the display screen body 110.

[0029] In addition, magnetic sub-buckles 121 are provided at the bottom ends of both sides of the connecting tube 120, and a magnetic female buckle 1522 is fixed at the top of the slider 152, and the magnetic sub-buckle 121 and the magnetic female buckle 1522 are attracted to each other, so that the nozzle 151 is conveniently fixed to one side of the connecting tube 120.

[0030] The working principle and use process of the utility model are as follows: when in use, the silent fan 142 is started to accelerate the air to the air supply pipe 130, and the high-speed air flow enters the connecting pipe 120 through the air supply pipe 130, and enters the nozzle 151 through the connecting pipe 120 to be ejected, and a top-down air flow wall is generated on the screen surface of the display screen body 110, so that when dust approaches the screen of the display screen body 110, it will fly away under the action of the air flow, and dust is prevented from adhering to the screen of the display screen body 110. When the screen of the display screen body 110 needs to be cleaned, the pull plates 153 on both sides are pinched with both hands and pulled downward, and the movement of the pull plates 153 drives the slider 152 to move downward, and the downward movement of the slider 152 drives the nozzle 151 to move downward, and the downward movement of the nozzle 151 drives the sponge pad 160 to move downward, so that the dust and impurities attached to the surface of the display screen body 110 are scraped off, and the surface of the display screen body 110 is cleaned.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
