Modern society, along with popularizing of university multimedia teaching instrument, more teacher replaces the process of blackboard traditional instruction by projector interactive teaching.After work for a long time, can produce the highest heat inside machine, the power supply of projector also can produce the highest heat；And the heat produced all converges in the internal narrow space of machine, the normal use of projector is not only brought impact by its high temperature produced, and can be greatly shortened the service life of inner member.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, this utility model provides the projector of a kind of good heat dissipation effect, and it uses many group radiator fan combinations, the heater element in projector housing can be carried out specific aim heat radiation, improve radiating effect further, extend its service life.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of projector imparted knowledge to students, including projector housing 1, it is arranged on the main lens 4 on front side of described projector housing 1 and secondary mirror head 5, described main lens 4 and secondary mirror head 5 are separated by baffle plate 6, upper and lower sides, left and right sides and the rear side of described projector housing 1 is provided with fan 7 and is positioned at the Air Filter inside fan 7；Being provided with hollow type support 8 bottom described projector housing 1, both sides are provided with fan 7 around；It is positioned at described projector housing 1 left and right sides and is positioned at the fan 7 of described support 8 left and right sides and is turbofan.
Preferably, described projector housing 1 is made up of high heat-conducting.
Preferably, being provided with chute 9 on front side of described projector housing 1, described secondary mirror head 5 slides through the most described chute of drive mechanism 9 in described chute 9.
Preferably, described drive mechanism is motor.
Preferably, also include being arranged on the temperature sensor in described projector housing 1 and alarm.
Preferably, also including the external control panel 2 being arranged on described projector housing 1 epipleural, it is connected with described main lens 4 and secondary mirror head 5.
Preferably, it is provided with cushion below described support 8.
It is highly preferred that described cushion is polyurethane shock pad.
This utility model has the advantages that this projector can effectively dispel the heat, and avoids dust to enter, and affects its work, and simple in construction is easy to use, with low cost, improves radiating effect, extends its service life；When temperature is too high can and alarm exist side by side circuit of cutting off the electricity supply, can effectively regulate its position.Project different pictures respectively by main lens and secondary mirror head, when needs project multiple picture when, can synchronize to realize the interaction of many image projection, the beneficially content of courses.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model projector.
Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, this utility model is a kind of projector for teaching, it includes projector housing 1, is arranged on the control panel 2 on the upside of described projector housing 1, for receiving the infrared receiver antenna 3 of remote controller signal, baffle plate 6 and main lens 4, secondary mirror head 5 for operate projector, wherein, described main lens 4 and secondary mirror head 5 are arranged on the front side of projector housing 1, and separated by described baffle plate 6, described baffle plate 6 tilts towards described secondary mirror head 5, and angle is preferably 20 °.Described projector also includes being separately positioned on the fan 7 of both sides up and down, the left and right sides and the rear side of described projector housing 1 and being positioned at the Air Filter of fan 7；Also including being positioned at the hollow type support 8 bottom described projector housing 1, its front height is higher than posterior height so that described projector has certain angle of inclination, it is simple to projection；The left and right sides of described hollow type support 8 is provided with fan 7；The fan 7 of the left and right sides of described projector housing 1 left and right sides and described hollow type support 8 is turbofan, the turbofan effect being positioned at described projector housing 1 left and right sides is air-out on rear side of housing 1 side air inlet, or the side air-out of rear side air intake, to realize the quick radiating effect of heat in described projector housing 1；The turbofan effect of the left and right sides being positioned at described support 8 is with minor bottom air intake or air-out, make bottom air inlet amount strengthen or air-out strengthens, wind direction track is that bottom described projector housing 1, bilaterally the internal air intake of housing 1 or housing 1 are internal to bottom bilateral air-out, improves radiating effect further.
A side region on front side of described projector is provided with chute 9, described secondary mirror head 5 is inlayed and is arranged in chute 9, drive described secondary mirror head 5 to slide in described chute 9 through drive mechanism, facilitate described secondary mirror head 5 to move left and right in described chute 9 for adapting to screen width and screen position.Described drive mechanism preferably but is not limited to motor.
Further, described infrared receiver antenna 3 uses concealed antenna 3, embeds and is arranged on control panel 2.Button in control panel 2 uses soft silica gel to make, and is embedded on control panel 2.
As preferably, described projector also includes being arranged on the temperature sensor in described projector housing 1 and alarm, when projector temperature is too high, can and alarm cut off the electricity supply, it is ensured that projector safety.
As preferably, in order to reduce the vibrations produced when fan 7 runs, cushion can be installed below described support 8, use the cushion that polyurethane material is made, good damping effect in an embodiment.
As preferably, described support 8 and described projector housing 1, for removably connecting, can increase or remove described support 8 as required.
