However, this filter is difficult to self-clean and easily becomes clogged after long-term use, affecting the projector's ventilation and reducing its heat dissipation efficiency. It requires regular disassembly and cleaning or replacement, which is troublesome, complicated, and impractical.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a dustproof structure and a projector.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0029] like Figures 1 to 6 As shown, in one embodiment of the present invention, the dustproof structure includes a dustproof structure guide chamber 1 and a rotating self-cleaning mechanism 2. The rotating self-cleaning mechanism 2 is installed inside the dustproof structure guide chamber 1. The rotating self-cleaning mechanism 2 includes a rotating filter assembly 21, a rotating power assembly 22, and a pair of rotating cleaning assemblies 23. The rotating filter assembly 21 is installed inside the dustproof structure guide chamber 1, the rotating power assembly 22 is fixedly installed on the dustproof structure guide chamber 1, and the pair of rotating cleaning assemblies 23 are fixedly installed inside the dustproof structure guide chamber 1.

[0030] The dustproof structure and the method of using the projector are as follows: When the projector is running, it will draw in air from the outside through its own heat dissipation system. The air can enter the dustproof structure guide chamber 1 through the rotating power component 22. At the same time, the rotating power component 22 can guide the air and drive the rotating filter component 21 to rotate. After filtering the air, the rotating filter component 21 can rub against the rotating cleaning component 23 while rotating. Through friction, the dust on the surface of the rotating filter component 21 is cleaned and falls into the dustproof structure guide chamber 1. Through the guidance of the dustproof structure guide chamber 1, it can be collected and made easy for the user to clean at any time.

[0031] like Figures 1 to 5 As shown, the rotating filter assembly 21 includes: a rotating support filter 211, a rotating support ring 212, and a rotating support connecting pipe 213. The rotating support filter 211 is disposed within the dustproof structure guide chamber 1. The rotating support filter 211 filters the passing air, reducing the amount of dust entering the projector body and improving the cleanliness of the projector body. Simultaneously, its rotation reduces the likelihood of clogging, and its rotation changes the airflow surface. The rotating support ring 212 is fixedly installed within the dustproof structure guide chamber 1. The rotating support ring 212 supports the rotating support filter 211, improving its stability and reducing the likelihood of it detaching. It also improves the balance of the rotating support filter 211, reducing the likelihood of dust leakage from both sides of the rotating support filter 211. The rotating support connecting pipe 213 is fixedly installed on the dustproof structure guide chamber 1. The rotating support connecting pipe 213 can connect the dustproof structure guide chamber 1 and the projector body, so that the projector body can be supplied with air for heat dissipation through the dustproof structure guide chamber 1.

[0032] like Figures 1 to 4As shown, rotating support bearings 214 are installed between the rotating support filter 211, the dustproof structure guide chamber 1, and the rotating support ring 212. The rotating support bearings 214 can reduce the friction between the rotating support filter 211, the dustproof structure guide chamber 1, and the rotating support ring 212, improve the stability of the rotation of the rotating support filter 211, reduce the difficulty of the rotating support filter 211 being driven by airflow, improve the smoothness of the rotation of the rotating support filter 211, and at the same time, reduce the probability of damage to the rotating support filter 211, the dustproof structure guide chamber 1, and the rotating support ring 212.

[0033] like Figures 1 to 4 As shown, both the dustproof structure guide chamber 1 and the rotating support ring 212 have positioning grooves that match the rotating support bearing 214. The positioning grooves help with the installation of the rotating support bearing 214, provide corresponding space for the installation of the rotating support bearing 214, and reduce the probability of the rotating support bearing 214 falling off. The rotating support connecting pipe 213 is set through the dustproof structure guide chamber 1, which facilitates the connection between the dustproof structure guide chamber 1 and the projector body.

[0034] like Figures 1 to 3 As shown, the rotating power assembly 22 includes: a rotating power connecting pipe 221, rotating power fan blades 222, and a rotating power collection chamber 223. The rotating power connecting pipe 221 is fixedly installed on one side of the dustproof structure guide chamber 1. The rotating power connecting pipe 221 connects the dustproof structure guide chamber 1 with the outside air, guiding the air to better contact the rotating power fan blades 222, causing the rotating power fan blades 222 to drive the rotating support filter 211 to rotate. The rotating power fan blades 222 are fixedly installed on the outside of the rotating support filter 211. Guided by airflow, the rotating power fan blades 222 can drive the rotating support filter 211 to rotate, allowing the windward surface of the rotating support filter 211 to change. The rotating power collection chamber 223 is slidably installed inside the dustproof structure guide chamber 1. The rotating power collection chamber 223 collects dust, facilitating cleaning and improving ease of use.

[0035] like Figures 1 to 3 As shown, both the rotating power connecting pipe 221 and the rotating power collection chamber 223 are installed through the dustproof structure guide chamber 1. The installation of the rotating power connecting pipe 221 through the dustproof structure guide chamber 1 connects the dustproof structure guide chamber 1 with the outside air, allowing outside air to enter the dustproof structure guide chamber 1. The installation of the rotating power collection chamber 223 through the dustproof structure guide chamber 1 facilitates the extraction of the rotating power collection chamber 223, making it convenient for users to clean.

[0036] like Figures 1 to 2As shown, multiple rotating power fan blades 222 are provided and are evenly distributed. The arrangement of multiple rotating power fan blades 222 can drive different rotating power fan blades 222 to the air outlet of the rotating power connecting pipe 221 when the rotating support filter 211 rotates. This allows different rotating power fan blades 222 to be subjected to the thrust of the air, thereby improving the rotational power of the rotating support filter 211.

[0037] like Figures 1 to 5 As shown, the rotating cleaning assembly 23 includes a support shaft 231, a mounting plate 232, and a rotary spring 233. The support shaft 231 is fixedly installed inside the dustproof structure guide chamber 1. The support shaft 231 improves the ease of rotation of the mounting plate 232, enhances its stability, reduces the likelihood of detachment, and improves its balance. The mounting plate 232 is rotatably mounted on the outside of the support shaft 231. The mounting plate 232 allows for the displacement of the rotating cleaning brush 234, enabling it to better contact the rotating support filter 211 and clean it more effectively. The rotary spring 233 is installed between the support shaft 231 and the mounting plate 232. The rotary spring 233 allows the mounting plate 232 to rotate, ensuring better contact between it and the rotating support filter 211, thus allowing the rotating cleaning brush 234 to clean the filter more effectively.

[0038] like Figures 1 to 4 As shown, a rotating cleaning brush 234 is fixedly installed at the end of the mounting plate 232 away from the support shaft 231, which can clean the rotating support filter 211 by friction with the rotating support filter 211.

[0039] like Figures 1 to 6 As shown, a projector includes a projector body and a dustproof structure body, the dustproof structure body being mounted on the projector body.
