Abstract
A wind forming demonstrator for demonstrating the forming of wind via process that hot air flows towards cold air, with excellent effect and use convenience, comprising a case body, right side wall of the case body is opened with vent hole, bottom of left side wall of the case body is opened with wax hole, the wax hole is hinged with a was cover board, the wax cover board is opened with a air inlet; right part of upper side wall inside the case body is hanged with flexible streamer; candle is disposed on wax hole inside of the case body; fore side wall of the case body comprises a transparent observation panel, the transparent observation plate is hermetically connected with the case body. When the candle is lighted, the hot air arises and flows out from the air vent, in order to form wind flowing from the air inlet to the air vent, so that the end part of the flexible streamer waves towards the air vent, with nice demonstration effect and operation convenience.
Description
Technical field
The utility model relates to a kind of teaching aid, relates in particular to a kind of formation demonstrator of wind.
Background technology
Now, thereby the demonstration hot-air is a flat rectangular parallelepiped to the mobile experiment teaching aid that forms wind of cold air direction in the teaching, in DeGrain when the student demonstrates, inconvenient operation.
Summary of the invention
The purpose of this utility model provides the formation demonstrator of a kind of effect wind obvious, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of formation demonstrator of wind comprises casing, it is characterized in that: casing right side wall top has venthole, and casing left side wall bottom has a wax mouth, and some wax mouth place is hinged a wax cover plate, has air admission hole on the some wax cover plate; The upper side wall right part of box house hangs with flexible ribbon; The box house at some wax mouth place is provided with candle; The front side wall of casing is transparent access panel, and transparent access panel is airtight the connection with casing.
Because the utility model hangs with flexible ribbon in casing, hot-air rises behind lighted candle, flows out from venthole, thereby form the wind that flows to venthole from air admission hole, waved to the venthole place in the lower end of flexible ribbon, the demonstration effect is obvious, and easy to operate.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the accompanying drawing: 1, casing; 2, flexible ribbon; 3, venthole; 4, candle; 5, some wax mouth; 6, some wax cover plate; 7, air admission hole.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described: a kind of formation demonstrator of wind, as shown in Figure 1, comprise casing 1, casing 1 right side wall top has venthole 3, casing 1 left side wall bottom has a wax mouth 5, point wax mouth 5 places are hinged a wax cover plate 6, has air admission hole 7 on the some wax cover plate 6; The upper side wall right part of casing 1 inside hangs with flexible ribbon 2; Casing 1 inside at some wax mouth 5 places is provided with candle 4; The front side wall of casing 1 is transparent access panel, and transparent access panel is airtight the connection with casing 1.
