Abstract
The present invention relates to a film-dilating mirror. A flexible reflected light film is dilated on a circular tube-shaped mirror frame, and particularly a reflected light film and a flexible film are dilated on double-film air pressure type flat, concave and convex multifunctional mirrors arranged at both surfaces of the mirror frame. The present invention is characterized in that the film-dilating mirror has an inflatable bag; when not inflated, the bag is flexible; when inflated, the bag is the mirror frame; when not used, the present invention provides a mirror which has the advantages of light weight, small volume and convenient carrying. The present invention can be made of plastic films. A large area concave mirror is easily provided so as to be used for solar energy spotlight, and is favourable for the popularity of solar energy utilization. The present invention reduces the exhaust of CO2 so as to provide conditions for solving the problem of earth greenhouse gas. The present invention is suitable for a portable solar cooker, and is convenient in use for farmers, herders and people of outdoor sports.
Description
The present invention is a kind of film-expanding lens, the flexible reflective membrane is opened on the circular pipe type picture frame, and especially a facet reflective film and a flexible film are opened, concave, convex Multi-function mirror flat in two film vapour-pressure types on picture frame two sides, and feature is inflatable bag, this bag is flexible when not inflating, and is picture frame when inflation.
Film-expanding lens is lighter than the mirror of generally making with rigid materials such as glass, and this is to help the condition of carrying, carrying, but the film-expanding lens of prior art is made picture frame with rigid material, and the glass mirror that volume is more general is big, unfavorable carrying.The purpose of this invention is to provide a kind of both light, the mirror that can be convenient for carrying volume-diminished again in time spent not.
The objective of the invention is to realize as follows: the flat picture frame of the air bag of tubular replaces the flat picture frame of rigidity circular pipe type of prior art, and making whole film-expanding lens all is the flexible material, can be folded into small size when not inflating, be convenient for carrying or preserve.
The present invention can use the plastic foil manufacturing, and the large tracts of land concave mirror is provided easily, for Salar light-gathering usefulness, helps popularizing the solar energy utilization, reduces CO2 emission, thereby provides condition for solving the global warming gas problem.It is suitable for and makes portable solar cooker, makes things convenient for peasant, herdsman, outdoorsman people to use.
Following embodiment elaborates to the present invention:
Figure one, be that top view 1. is flexible reflective membranes, the reflective plastic foil of present embodiment.
Figure two, be that side view 2. is flat picture frames of air bag of tubular, the present embodiment plastic film bag.
Figure three, being that bottom view 2. is flat picture frames of air bag of tubular, 3. is flexible film (present embodiment overlays), 4. is gas ports of the flat picture frame of air bag of tubular, 5. is gas ports of two film vapour-pressure type mirrors.
Figure four, be cross section, show that two film air pressure mirrors are subjected to partly vacuum concavity by the diameter of gas port.1. being the flexible reflective membrane, 2. is flat picture frames of air bag of tubular, 3. is flexible films, 4. is gas ports of bag, 5. is gas ports of air pressure mirror.As to 5 inflations, 1. one-tenth convex lens then, open 5 Cheng Pingjing, it is collapsible to open 4 whole mirrors.
Figure five, be the portable solar cooker that has disposed portable pillar, the 6th, portable pillar, present embodiment is with the scalable post of telescope cartridge type.
Because open film concave mirror adjustable focal length, the thing that is heated can be fixed, needn't follow the tracks of the sun with the mirror interlock.
Claims (3)
1. an one side flexible reflective membrane (1) and a flexible film (3) the concavo-convex multi-functional speculum of two film vapour-pressure types on the flat picture frame of circular pipe type air bag (2), it is characterized in that the flat picture frame of this circular pipe type air bag (2) connects gas port (4), flexible film (3) connects gas port (5), can be by the air pressure mode with the recessed speculum of this speculum furnishing, also can the furnishing convex reflector, the flat picture frame of described circular pipe type air bag is a flexible when not inflating, and is picture frame when inflation.
2. speculum as claimed in claim 1 is characterized in that when the air cavity between airbag (2), flexible reflective membrane (1) and the flexible film (3) was negative pressure, flexible reflective membrane (1) was recessed speculum, its adjustable focal length when airbag (2) inflation.
3. speculum as claimed in claim 1 is characterized in that when the air cavity between airbag (2), flexible reflective membrane (1) and the flexible film (3) was malleation, flexible reflective membrane (1) was a convex reflector when airbag (2) inflation.
