Description

TECHNICAL FIELD

[0002] As a common display device, the projector is widely used in the fields of home entertainment, business office and education. The design of the traditional projector usually adopts the structure of horizontal projection, that is, the lens module is installed in parallel with the horizontal plane. Although this design is simple, it has certain limitations. First of all, due to the large volume of the projector, the space requirement is high, especially when used in limited space, it is often difficult to find a suitable placement position. In addition, the air inlet and air outlet of the traditional projector are usually designed at the bottom of the shell. Although this design can be hidden at the bottom of the device to avoid interfering with the user's vision, it brings another problem - the light emitted by the light source assembly is easy to leak from the air inlet or air outlet at the bottom, resulting in reduced utilization of the light source, and also affecting the shading of the projection effect.

[0003] On the other hand, the heat dissipation design of the traditional projector mainly relies on blowing air out from the inside of the device through the fan. This "blowing" heat dissipation method has the problem of low efficiency, especially in the case of a large amount of heat generated by the light source assembly and the projection assembly, the heat dissipation effect is difficult to meet the expectation, which may cause the device to overheat, affecting the service life and projection effect of the projector.

[0004] In order to solve the above problems, some improved projector designs appear in the market, such as adjusting the position of the air inlet and air outlet to optimize the heat dissipation effect, or changing the angle of the lens module to reduce the size of the device and improve the space utilization. However, these improvements still have deficiencies in the specific implementation process, especially in terms of balancing the miniaturization of the device and the heat dissipation performance, the existing technology still has certain limitations.
