Problems solved by technology

The first airflow 54' passing through the light-emitting element 12' is actually a hot airflow. At this time, the first fan 41' is in a stopped state, and there is no obstruction between the light-emitting element 12', and the hot airflow passing through the light-emitting element 12' Blowing the first fan 41' can easily cause the first fan 41' to be deformed by heat, and even other electronic components in the first cooling part 40' may have functional failures, which will affect the life of the projector and even pose a safety hazard

Embodiment Construction

[0023] Please refer to figure 2 , image 3 , figure 2 is a schematic diagram of the projection device of the present invention, image 3 It is a schematic diagram of the first use state of the combination of the light source module and the first and second cooling parts in the projection device of the present invention. combine figure 2 and image 3 It can be seen that the projection device 1 has a light source module 10 , a first cooling unit 40 and a second cooling unit 50 . The first cooling part 40 and the second cooling part 50 are used for cooling the light source module 10 . The light source module 10 has opposite first side 15 and second side 16, the first cooling part 40 is arranged on the first side 15 of the light source module 10, and the second cooling part 50 is arranged on the second side 16 of the light source module 10 .

[0024] like image 3 As shown, the first cooling unit 40 includes a first fan 41 and a first air outlet 42 . The first fan 41 c...

Abstract

The invention relates to a projector device. The projector device comprises a light source module, a first cooling part and a second cooling part. The light source module is provided with a first side and a second side which are opposite. The first cooling part is arranged on the first side and comprises a first air fan and a first air outlet. The second cooling part is arranged on the second side and comprises a second air fan and a second air outlet. The second air outlet and the first air outlet are correspondingly arranged. When the first cooling part operates and the second cooling part stalls, the first air fan is turned on and the second air fan is turned off, a first air current enables a first valve to open and blows towards a second valve after passing the first air outlet, and therefore the second valve turns off the second air outlet. Due to the fact that valves are arranged on the cooling part between the air fan and the light source module, hot air current can be prevented from blowing the air fan or other elements close to the air fan. The projector device has the advantages that deformation of the air fan due to being heated can be avoided, damages to other components can be avoided, the service life of the projector device is prolonged, and a reliability problem can be solved.

Description

technical field [0001] The invention relates to a projection device, in particular to a projection device using a valve to protect a fan. Background technique [0002] Projectors have the advantages of large screen and small size, and the brightness and resolution of projectors have been greatly improved in recent years, making projectors more and more popular in office presentations and home theaters. With the generation of interactive projectors, in addition to the original two states of use (that is, one is placed on a platform or table, and the other is suspended from the ceiling), the projector can even rotate 360°. According to the different usage modes of the projector, the one used to cool the light source module is also changed from the original one to two. [0003] Please refer to figure 1 , figure 1 It is a schematic diagram of a use state of the combination of the light source module and the first and second cooling parts in the prior art. like figure 1 As s...
