Problems solved by technology

However, as the use time increases, the amount of dust deposited on the filter will also increase, making the airflow introduced by the fan smaller, thereby reducing the heat dissipation efficiency of the fan
At this time, the user must disassemble the filter screen to clean or replace a new filter screen, which is inconvenient for the user

Embodiment Construction

[0025] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.

[0026] see figure 1 as well as figure 2 , figure 1 is an appearance diagram of a projector 1 according to an embodiment of the present invention, figure 2 for figure 1 Bottom view of Projector 1. like figure 1 As shown, the projector 1 includes a casing 10 and a lens 12 . The lens 12 is disposed in the housing 10 and exposed from the housing 10 . In addition to the lens 12 , the housing 10 is also provided with optical components (not shown in the figure) required for imaging, such as a light source device, an optical module, and the like. The light source device is used for emitting light beams, and the light beams are processed by the optical module and then projected into images through the lens 12 . In actual application, the optical module may be a so-c...

Abstract

The invention relates to a projector and an airflow guidance device thereof. The airflow guidance device comprises a guidance passageway, an isolator, a first fan and a second fan. The guidance passageway comprises a first passageway and a second passageway, wherein the first passageway is provided with a first opening, the second passageway is provided with a second opening, and the first opening and the second opening are respectively located at the two ends of the guidance passageway. The isolator is arranged between the first passageway and the second passageway, and can be operated to isolate or communicate the first passageway and the second passageway selectively. The first fan is arranged at the first opening, and the second fan is arranged at the second opening. By the invention,a user can clear away dust on a filter screen without needing demounting the filter screen.

Description

technical field [0001] The present invention relates to a projector, in particular to a projector with an airflow guiding device, and the airflow guiding device can automatically remove filter dust. Background technique [0002] Recently, projectors have been widely used. In addition to being used for conference reports in general offices, projectors are also often used in various seminars or academic courses due to their audio-visual playback capabilities. Generally speaking, a projector has a cooling system, which uses a fan to blow external air into the casing of the projector to cool the heat generated by heat sources (such as light source lamps, optical engines, etc.). [0003] In order to prevent the dust entrained in the air from entering the projector, a filter screen is usually installed near the air inlet and outlet of the projector. However, as the use time increases, the amount of dust deposited on the filter will also increase, making the airflow introduced by...
