Description of the Invention: [Technical Field] The present invention relates to an auxiliary device for use in disassembling a light bulb of a projector, and more particularly to an anti-bulb eye protection device for an inverted projector. [Prior Art] When the projector's lamp is broken, it can be removed and replaced by the lamp removal port on the top, but when the projector is mounted on the ceiling, its top is facing down. When the bulb is removed, fragments of the bulb may fall and stab the human eye. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a flip-chip projector for disassembling a bulb eye protection device that can ensure personal safety. An upside down projector disassembles a bulb eye protection device having a bulb removal opening at the top of the projector. The eye protection device includes an inner ring, an outer ring and a flexible bag. The inner ring is larger than the size of the bulb detaching port, and the outer ring is matched with the inner ring, the diameter of the flexible bag is not smaller than the size of the inner ring, and the opening edge of the flexible bag is clamped to Between the inner ring and the mating surface of the outer ring. Since the eye protection device of the present invention can completely cover the bulb removal opening, when the broken bulb of the inverted projector is replaced, the fragments of the broken bulb will fall into the bag without directly dropping the stab wound from the bulb removal opening. The human eye avoids damage to the human eye and ensures personal safety. [Embodiment] Please refer to FIG. 1 , which is an inverted projector 1 having a protective cover 2 , two screws 3 , and a bulb module 4 . In the embodiment, there are two screw holes lb around the bulb removal opening 1a. The protector 2 has two fixing portions 2a' each having a screw hole 2b. The dowel 3 passes through the screw holes 2b, lb to fix the protective cover 2 to the bulb removal opening la. 2 4 ^ Please refer to FIG. 2A, the 4th embodiment of the present invention provides a 4 detachable camera removing light bulb protection device 100, which comprises an inner ring 10,

The flexible bag 30 has an opening portion 30a and a receiving portion fee #. The ring 10 and the outer ring 2 are made of an elastic material. In the present embodiment, the inner ring 10 and the outer ring 20 may be round, square or elliptical. & The inner ring 1〇 has a larger inner diameter than the bulb but 0 乂. Insufficient, the outer diameter of the inner ring 10 is tight with the inner ring of the outer ring 2〇. The inner ring 10 has a plurality of open slots 1 〇 c. In this embodiment, the inner ring 10 is open to the outer ring 2 。. The protrusion (10) of the inside of the housing 10 is adjacent to the recess 2c of the outer ring 20, and the image ring 10 can be engaged with the outer ring 2 so as not to fall off. The 铐~ material is a transparent material. In this embodiment, a transparent sun-moon plastic bag is used. 7 200921251 The opening 30a of the sexual bag 30 is not smaller than the outer diameter of the inner ring 10, and when assembled, the opening 30a is sandwiched between the outer ring 10b and the outer ring 20 Face 20a is between the mating faces. The fixing portion 40 is connected to the inner ring 10, and may be bonded by adhesive or hot melt. In this embodiment, it is an integral structure. The fixing portion 40 has two screw holes 40a corresponding to the two screw holes lb around the bulb removal opening la. The protective device 100 may not have the fixing portion 40, and in use, the outer ring 20b of the outer ring 20 may be held for the purpose of use. Please refer to FIG. 3 , which is a state diagram of the use of the eye protection device. When the projector 1 is hoisted on the ceiling and the lamp is to be replaced, the eye protection device 100 is assembled first. The assembly method is to clamp the opening 30a of the flexible bag 30. Between the inner ring 10 and the outer ring 20. Then, the protective cover 2 of the projector 1 is removed. When the bulb module 4 is withdrawn, the bulb fragments may fall out with the bulb module 4, so that the inner ring 10 of the eye protection device 100 faces the bulb removal opening la of the projection lamp 1, and the eyebrows are passed through the eyepiece with the screw 3. The screw hole 40a of the fixing portion 40 of 100 fixes it to the projector 1. The bulb module 4 in the projector 1 is taken out through the flexible bag 30. Referring to FIG. 4, the second embodiment 200 of the present invention is substantially the same as the eye protection device 100 provided in the first embodiment, and the same components are denoted by the same reference numerals as in FIG. 2 and will not be described again. The difference is that the fixing portion 40 of the eye protection device 200 is attached to the outer ring 20. Since the eye protection device of the present invention completely covers the bulb removal opening, when the broken bulb of the inverted projector is replaced, the fragments of the broken bulb will fall into the bag without directly puncturing the human eye from the bulb removal opening. , thus avoiding 8 200921251 eye damage to people, to ensure personal safety. In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law. However, the above description is only the preferred embodiment of the present invention, and the scope of the present invention is not limited to the above-described embodiments, and equivalent modifications or variations made by those skilled in the art in light of the spirit of the present invention are It should be covered by the following patent application.
