Abstract
The utility model discloses a formation demonstrator for cloud and fog. The formation demonstrator for cloud and fog structurally comprises a test bed, a water container, a glass cover, a heat source and a cool air generation device, wherein the glass cover is hung just above the test bed via a support, and a U-shaped tray is arranged at the lower end of the glass cover; the water container and the cool air generation device are fixed at the both ends of the test bed respectively; the water container is heated via the heat source; and the water container and the cool air generation device are connected in the glass cover via lead tubes and controlled by a control valve respectively. The formation demonstrator for cloud and fog disclosed by the utility model is used for demonstrating the formation processes of cloud and fog by controlling hot air and cool air entering in the glass cover, and students can visually observe the formation processes of the state changes.
Description
Technical field
The utility model relates to a kind of teaching aid, the formation demonstration device of especially a kind of cloud, mist.
Background technology
At present, the student just recognizes corresponding principle from books when weather phenomena such as the relevant cloud of Learning in School, mist, but more abstract to its forming process, and teacher very can not be very vivid demonstrates these states of matters to students and change and how to form.
The utility model content
The purpose of this utility model is to provide the formation demonstration device of a kind of cloud, mist, the formation demonstration device of this cloud, mist overcome in the prior art can not be very vivid these states of matters of demonstration change and be the problem how to form, simple to operate, be easy to observe.
The technical scheme that its technical matters that solves the utility model adopts is: the formation demonstration device of a kind of cloud, mist, comprise testing table, water container, cloche, thermal source and cold air generation device, described cloche is suspended on directly over the testing table by support, there is a U-shaped pallet lower end, described water container and cold air generation device are individually fixed in the two ends of testing table, described water container heats by thermal source, described water container and cold air generation device insert cloche inside by conduit, are controlled by operation valve respectively.
The utlity model has following outstanding beneficial effect: the formation demonstration device of cloud of the present utility model, mist, enter the hot gas of cloche and the forming process that cold air is demonstrated cloud, mist by control, the forming process of observing these states of matters variations that students can be very vivid.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 1 description of symbols: 1 testing table, 2 water containers, 3 cloches, 4 thermals source, 5 cold air generation devices, 6 supports, 7U shape pallet, 8 conduits, 9 operation valves.
Embodiment
As shown in Figure 1, the formation demonstration device of cloud of the present utility model, mist, its structure comprises testing table 1, water container 2, cloche 3, thermal source 4 and cold air generation device 5, described cloche 3 is suspended on directly over the testing table 1 by support 6, there is a U-shaped pallet 7 lower end, described water container 2 and cold air generation device 5 are individually fixed in the two ends of testing table, and described water container logical 2 is crossed thermal source 4 heating; Described water container 2 and cold air generation device 5 insert cloche 2 inside by conduit 8, respectively by operation valve 9 controls.
Use cloud of the present utility model, the formation demonstration device of mist, earlier the cold air that produces in the cold air generation device 5 of testing table 1 right-hand member is imported in the cloche 3 by conduit 8, the water vapor that water in the water container 2 of thermal source 4 heating heating back is produced imports in the cloche 3 by conduit 8 again, by the water vapor of operation valve 9 control importings and the amount of cold air, water vapor in the cloche 2 runs into cold air and just is liquefied as the minimum globule or sublimates into minimum ice crystal above cloche 2, a large amount of droplets and little ice crystal float over cloche 2 tops, just formed cloud, the water vapor of cloche 2 belows has just formed mist.Use the method, the industry situation that can also demonstrate in the physical knowledges such as rain, snow, dew, frost and hail changes.Students can be very vivid observe the forming process that these states of matters change, increased students'interest in learning.
