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 external view of a projector 1 according to an embodiment of the present invention, figure 2 for figure 1 The bottom view of projector 1. Such as figure 1 As shown, the projector 1 includes a housing 10 and a lens 12. The lens 12 is arranged in the housing 10 and is exposed outside 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 and an optical module. The light source device is used to emit a light beam, and the light beam is processed by the optical module and then projected and imaged through the lens 12. In practical applications, the optical module can be a so-called optical engi...

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 openingand 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 invention relates to a projector, in particular to a projector with an airflow guiding device, which can automatically remove dust on a filter screen. Background technique [0002] Recently, the application of projectors has become more and more extensive. In addition to meeting reports in general offices, projectors are often used in various seminars or academic courses due to their audio-visual playback functions. Generally speaking, a projector has a cooling system, which uses a fan to blow an external airflow into the housing of the projector to cool the heat generated by a heat source (such as a light source lamp, an optical engine, etc.). [0003] In order to prevent dust entrained in the air from entering the projector, a filter 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 also increases, making the airflow introduced by the fan smaller, thereby...
