Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. In the embodiments of the present utility model, the different types of cross-sectional lines are not labeled according to national standards, nor do they specify material requirements for the components; they are used to distinguish the cross-sectional views of the components in the drawings.

[0019] Please see Figure 1-3 A projector filter device capable of filtering fine dust is disclosed. This filter device is used to dissipate heat from the internal air of the projector. The filter device consists of a turbine fan 2, a large-diameter filter screen 4, and a support frame 5. The turbine fan 2 is located on the right side inside the projector body 1, and the turbine fan outlet 3 is located on the far right side of the turbine fan 2. The right end of the projector body 1 has a large-area air inlet 6, and the projector body 1 has a projector accessory mounting bracket 7 inside. The upper right side of the projector accessory mounting bracket 7 has projector accessory mounting holes 10, and the top left side of the projector accessory mounting bracket 7 has a gasket 9. The projector body 1 is fixed to the projector cover by screws 8.

[0020] Among them, the turbo fan 2 is an adjustable speed fan.

[0021] Among them, the large-diameter filter screen 4 uses 120g of material, which can filter fine dust, has an air permeability of more than 2500L / M2.S, a tensile strength of more than 230N, and a bursting strength of more than 100KPa.

[0022] Among them, the large-diameter filter screen 4 is a 160*79mm large-diameter waler structure filter surface.

[0023] Among them, the support frame 5 is made of rigid non-woven fabric, which can support the entire structure without deformation and ensures structural stability.

[0024] The air blown from the turbine fan outlet 3 is directed at the filter surface of the large-diameter filter screen 4.

[0025] The working principle and usage process of this utility model: The projector filter device that can filter fine dust consists of three main parts: turbine fan 2, large-diameter filter screen 4, and support frame 5.

[0026] Turbine fan 2 uses an adjustable speed fan and features low noise, good speed range, high reliability in high temperature operation, adaptability to high temperature and humidity, and adaptability to fine dust. In short, it has strong applicability and reliability.

[0027] Large-diameter filter screens 4 are generally available in these specifications: 60g / 80g / 100g / 120g / 130g, etc. This design uses 120g material, which can filter fine dust. The disadvantage is poor air permeability, which is greater than 2500L / M2.S. The tensile strength is greater than 230N, and the bursting strength is greater than 100KPa. Based on the material characteristics, due to its poor air permeability but good tensile and bursting strength, a large-diameter 160*79 (mm) waler structure filter surface is designed, and it is combined with a vortex fan 2 to actively draw in cold air for internal circulation, remove the internal high temperature, and maintain internal temperature balance to ensure product reliability.
