[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0021] Please refer to the following: Figures 1-4 This utility model provides a technical solution: a dust filter device for an electric window opener, including a window opener body 1. A chain 2 is installed inside the window opener body, and the chain 2 is connected to a drive mechanism inside the window opener body. A protective frame 3 is fixedly connected to the front outer surface of the window opener body 1. A first brush 4 is fixedly connected to the top inner surface of the protective frame 3 and the front outer surface of the window opener. Springs 5 ​​are fixedly connected to the left and right inner walls of the protective frame 3. A second brush 6 is fixedly connected to the other end of each spring 5. Specifically, when the drive mechanism inside the window opener body 1 drives the chain 2 to move, the chain 2 contacts the first brush 4 and the second brush 6. The first brush 4 and the second brush 6 remove dust from the surface of the chain 2. Under the elastic force of the spring 5, the second brush 6 adheres tightly to the surface of the chain 2, removing dust from the surface of the chain 2. The filter 13 reduces the possibility of dust entering the interior of the window opener body 1, thereby preventing dust from affecting the internal power mechanism and extending the service life of the window opener body 1.

[0022] In this embodiment, a support shaft 8 is rotatably connected to the inner surface of the protective frame 3, and a gear 9 is fixedly sleeved on the outer surface of the support shaft 8. Multiple sets of teeth 7 are provided at the bottom of the chain 2. The gear 9 and the outer surface of the teeth 7 are movably meshed. A guide rod 10 is fixedly sleeved on the outer surface of the support shaft 8. Specifically, when the chain 2 moves, it drives the teeth 7 on it to move. When the teeth 7 mesh with the gear 9, it drives the gear 9 to rotate. The gear 9 drives the support shaft 8 to rotate. The support shaft 8 drives the guide rod 10 to rotate. When the guide rod 10 rotates, it contacts the second brush 6 and shakes off the dust on the second brush 6.

[0023] In this embodiment, a bending rod 11 is fixedly connected to the other end of the chain 2, and a mounting block 12 is fixedly connected to the other end of the bending rod 11. Specifically, the mounting block 12 is connected to the window, and the chain 2 moves to push the bending rod 11, so that the mounting block 12 drives the window and opens the window.

[0024] In this embodiment, a receiving box 14 is movably connected to the inner surface of the protective frame 3. The receiving box 14 is located below the second brush 6. Specifically, dust falls into the receiving box 14 for collection, and the receiving box 14 is removed to clean the dust.

[0025] In this embodiment, a filter screen 13 is provided at the connection between the outer surface of the window opener body 1 and the chain 2. Specifically, the filter screen 13 reduces the possibility of dust entering the interior of the window opener body 1.

[0026] In this embodiment, a coil spring 15 is fixedly wound around the outer surface of the support shaft 8, and a connecting plate is fixedly connected to the inner surface of the protective frame 3. The other end of the coil spring 15 is fixedly connected to the connecting plate. Specifically, when the support shaft 8 rotates, it causes the coil spring 15 on it to deform. When the rack and gear 9 disengage, the coil spring 15 is reset, thereby resetting the support shaft 8.

[0027] In this embodiment, there is a gap between each set of teeth 7, and they are arranged in a linear array. Specifically, when the chain 2 moves to the point where the gap between the teeth 7 contacts the gear 9, the coil spring 15 drives the support shaft 8 to reset the support shaft 8.

[0028] Working principle: When in use, the drive mechanism inside the window opener body 1 drives the chain 2 to move. The chain 2 pushes the mounting block 12, which opens the window. When the drive mechanism inside the window opener body 1 drives the chain 2 to move, the chain 2 comes into contact with the first brush 4 and the second brush 6. The first brush 4 and the second brush 6 remove dust from the surface of the chain 2. Under the elastic force of the spring 5, the second brush 6 is pressed tightly against the surface of the chain 2 to remove dust. The filter screen 13 reduces the possibility of dust entering the interior of the window opener body 1, thereby preventing dust from affecting the internal power mechanism and extending the service life of the window opener body 1.

[0029] When chain 2 moves, it drives the teeth 7 on it to move. When teeth 7 mesh with gear 9, it drives gear 9 to rotate. Gear 9 drives support shaft 8 to rotate. Support shaft 8 drives guide rod 10 to rotate. When guide rod 10 rotates, it contacts the second brush 6, shaking off the dust on the second brush 6 to prevent excessive dust accumulation on the second brush 6. The dust falls into the receiving box 14 for collection. The receiving box 14 is then removed and the dust is cleaned.

[0030] It is worth noting that the drive mechanism inside the main body 1 of the window opener is the core component of the entire device to realize the functions of opening and closing windows. It is usually composed of a motor, a reduction gear, a transmission component and a chain 2, etc. The various parts work together to realize power transmission and motion conversion.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
