[0043] Two first chutes 4, the two first chutes 4 are symmetrically opened on one side of the waterproof mask 2, a sliding rod 5 is slidably connected between the two first chutes 4, the sliding rod 5 is internally threadedly connected to two threaded rods 6, and the two threaded rods 6 are respectively located in the two first chutes 4 and are rotatably connected to the two first chutes 4;

[0044] A driving assembly is located inside the waterproof mask 2 and is used to drive the two threaded rods 6 to rotate;

[0045] The slot 7 is provided on the inner wall of the slide bar 5 and is connected to the outside. The wiper 8 is inserted into the slot 7, and one side of the wiper 8 is in contact with the surface of the transparent glass 3.

[0046] The fixing component is located inside the slide bar 5 and is used to fix the wiper 8.

[0047] Example 2:

[0048] This embodiment provides a face mask for an LED display screen. In addition to the technical solutions of the above embodiments, it also has the following technical features. The driving component includes:

[0049] Two first rotating grooves 9 are symmetrically arranged in the waterproof mask 2 and communicate with the two first chutes 4. Two worm gears 10 are rotatably connected in the two first rotating grooves 9, and one end of the two worm gears 10 extends into the two first chutes 4 and is fixed to one end of the two threaded rods 6 respectively.

[0050] A second rotating groove 11 is provided in the waterproof mask 2 and communicates with the two first rotating grooves 9. A worm group 12 meshing with the two worm wheels 10 is rotatably connected in the second rotating groove 11;

[0051] The waterproof shell 13 is fixedly connected to the top surface of the waterproof mask 2. A mounting groove 14 is provided in the waterproof shell 13. A motor 15 is fixedly connected in the mounting groove 14. The output shaft of the motor 15 passes through the inner wall of the mounting groove 14 and the top surface of the waterproof mask 2, and extends to the second rotating groove 11 and is fixed to one end of the worm gear group 12.

[0052] Among them, when in use, rainwater from the outside will be blocked by the waterproof mask 2 and the transparent glass 3 to prevent rainwater from directly contacting the LED display screen body 1. When rainwater attached to the surface of the transparent glass 3 affects the clarity of information on the LED display screen body 1, the user starts the motor 15, and allows the output shaft of the motor 15 to drive the worm group 12 to rotate in the second rotating groove 11, so that the worm group 12 drives the two worm wheels 10 to rotate in the two first rotating grooves 9 respectively, and allows one end of the two worm wheels 10 to drive the two threaded rods 6 to rotate in the two first sliding grooves 4 respectively. When the two threaded rods 6 rotate, the sliding rod 5 will be affected by the threads of the two threaded rods 6 to move along the two first sliding grooves 4, ensuring that the sliding rod 5 can drive the wiper 8 to scrape off the rainwater attached to the transparent glass 3, thereby preventing rainwater from affecting the clarity of information on the LED display screen body 1.

[0053] Example 3:

[0054] This embodiment provides a face mask for an LED display screen. In addition to the technical solutions of the above embodiments, it also has the following technical features: one end of the worm gear 10 is rotatably connected to the first slide groove 4.

[0061] Here, it is ensured that the output shaft of the motor 15 can rotate normally in the waterproof mask 2.

[0062] Example 6:

[0063] This embodiment provides a face mask for an LED display screen. In addition to the technical solutions of the above embodiments, it also has the following technical features. The fixing component includes:

[0064] The second slide groove 16 is opened on the inner wall of the slot 7 and is connected to the outside world. A baffle 17 is slidably connected in the second slide groove 16, and the top surface of the baffle 17 is in contact with the bottom surface of the wiper 8. A spring 18 fixed to the inner wall of the second slide groove 16 is fixedly connected to the baffle 17. A pull rod 19 is fixedly connected to one side of the baffle 17, and one end of the pull rod 19 passes through the second slide groove 16 and extends to the outside world and is slidably connected to the second slide groove 16.

[0065] Among them, when the surface of the wiper 8 is covered with dust, the user pulls the pull rod 19 by hand, allowing the pull rod 19 to drive the baffle 17 to slide in the second slide groove 16 and compress the spring 18. When the baffle 17 moves to the appropriate position, the baffle 17 will release the fixation of the wiper 8. The user then pulls the wiper 8 out of the slot 7 by hand and cleans the wiper 8 to prevent the dust on the surface of the wiper 8 from dirtying the transparent glass 3. The user then reinserts the cleaned wiper 8 into the slot 7 by hand and releases the hand pulling the pull rod 19, allowing the baffle 17 to slide in the opposite direction along the second slide groove 16 under the action of the rebound force of the spring 18. When the baffle 17 moves in the opposite direction to the appropriate position, the baffle 17 will fix the wiper 8 in the slot 7 and cannot move, ensuring that the user can quickly remove the wiper 8 from the slot 7 for cleaning.

[0066] During use, rainwater from the outside will be blocked by the waterproof mask 2 and the transparent glass 3 to prevent the rainwater from directly contacting the LED display screen body 1. When the rainwater attached to the surface of the transparent glass 3 affects the clarity of the information on the display screen of the LED display screen body 1, the user starts the motor 15, and the output shaft of the motor 15 drives the worm group 12 to rotate in the second rotation groove 11, so that the worm group 12 drives the two worm wheels 10 to rotate in the two first rotation grooves 9 respectively, and one end of the two worm wheels 10 drives the two threaded rods 6 to rotate in the two first sliding grooves 4 respectively. When the two threaded rods 6 rotate, the sliding rod 5 will be affected by the threads of the two threaded rods 6 to move along the two first sliding grooves 4, ensuring that the sliding rod 5 can drive the wiper 8 to scrape off the rainwater attached to the transparent glass 3, thereby preventing the rainwater from affecting the clarity of the information on the display screen of the LED display screen body 1.

[0067] When the surface of the wiper 8 is covered with dust, the user pulls the pull rod 19 by hand, allowing the pull rod 19 to drive the baffle 17 to slide in the second slide groove 16 and compress the spring 18. When the baffle 17 moves to the appropriate position, the baffle 17 will release the fixation of the wiper 8. The user then pulls the wiper 8 out of the slot 7 by hand and cleans the wiper 8 to prevent the dust on the surface of the wiper 8 from dirtying the transparent glass 3. The user then reinserts the cleaned wiper 8 into the slot 7 by hand and releases the hand pulling the pull rod 19, allowing the baffle 17 to slide in the opposite direction along the second slide groove 16 under the action of the rebound force of the spring 18. When the baffle 17 moves in the opposite direction to the appropriate position, the baffle 17 will fix the wiper 8 in the slot 7 and cannot move, ensuring that the user can quickly remove the wiper 8 from the slot 7 for cleaning.

[0068] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of this application, ordinary technicians in this field can also make many forms without departing from the purpose of this application and the scope of protection of the claims, all of which are within the protection of this application.
