Abstract
The utility model discloses a hand battery demonstration device which includes a skeleton (5). The skeleton (5) is provided with a copper plate (6) and a zinc plate (7). One end of an ammeter (3) is connected with the copper plate (6), and the other end is connected with the zinc plate (7). In use, two hands contact with the copper plate (6) and the zinc plate (7), and the ammeter (3) deflects. The operation is convenient, vivid and interesting, the visitor interest can be attracted, and the excellent scientific knowledge popularization effect is realized.
Description
Technical field
The utility model belongs to science popularization experimental demonstration device field, relates in particular to a kind of torch pond apparatus for demonstrating.
Background technology
The tradition volt reaches battery demonstration device (as shown in Figure 3) and adopts two flask splendid attire electrolytic solution, and connect electrolytic solution in two flasks with salt bridge, and in two flasks, insert respectively copper rod and zinc bar, between copper rod and zinc bar, connect reometer, adopt such device to demonstrate the principle of work that volt reaches battery, such structure operation inconvenience, do not have globality, be difficult for carrying and preserve, there are not simultaneously enough interests, be difficult to reach raising visitor interest, the effect of popularizing science better.
The utility model content
For the defective that the tradition volt reaches battery demonstration device operation inconvenience, is difficult for carrying and preserves, technical problem to be solved in the utility model provides a kind of easy to operate, and the torch pond apparatus for demonstrating of battery principle is showed on vivid and interesting ground.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of torch pond apparatus for demonstrating, comprise skeleton, described skeleton is provided with the reometer bracing frame, and be provided with reometer and pack in the described reometer bracing frame, also be provided with copper coin and zine plate on the described skeleton, described reometer one end is connected with described copper coin, and the other end is connected with described zine plate.
Described copper coin and the zine plate back side are provided with cooling piece, and are provided be used to the cooling piece bracing frame that supports described cooling piece.
Described skeleton is black acrylic skeleton.
The utility model has the advantage of, whole volt is reached the battery demonstration device to be integrated, do as a whole, convenient carrying with preserve, during use, people's both hands contact respectively copper coin and zine plate, reometer deflects, and is easy to operate, vivid and interesting, help to attract visitor's interest, reach the effect of better popularizing science.
Description of drawings
Fig. 1 is the structural representation of a kind of torch of the utility model pond apparatus for demonstrating;
Fig. 2 is the structural representation of Fig. 1 torch pond apparatus for demonstrating;
Fig. 3 is the prior art structural representation;
Mark among the above-mentioned figure is: 1, cooling piece, 2, the cooling piece bracing frame, 3, reometer, 4, the reometer bracing frame, 5, skeleton, 6, copper coin, 7, zine plate.
Embodiment
Fig. 1 and Fig. 2 are the structural representation of a kind of torch of the utility model pond apparatus for demonstrating, comprise skeleton 5, skeleton 5 is provided with reometer bracing frame 4, and be provided with reometer 3 and pack in the reometer bracing frame 4, also be provided with copper coin 6 and zine plate 7 on the skeleton 5, reometer 3 is connected with copper coin 6 by wire one end, and the other end is connected with zine plate 7.Copper coin 6 and zine plate 7 back sides are provided with cooling piece 1, and are provided with for the cooling piece bracing frame 2 that supports cooling piece 1.Skeleton 5 is black acrylic skeleton.
During use, people's both hands contact respectively copper coin 6 and zine plate 7, and reometer 3 deflects, and with sweat, and sweat is a kind of dielectric on the staff, and a certain amount of negative ions is contained in the inside.Zine plate 7 is more active than copper coin 6, the negative ion generation chemical reaction on the zine plate 7 in the sweat, and outer-shell electron is stayed on the zine plate 7, make zine plate 7 gather a large amount of negative charges, gather a large amount of positive charges on the copper coin 6.When with wire copper coin 6 and zine plate 7 being coupled together, the electronics on the zine plate 7 will move to copper coin 6 by reometer 3, have electric current to pass through in wire, thereby produce electric current.So reometer 3 needle deflection.This has in fact just consisted of a simple primary element.
After adopting such structure, whole volt is reached the battery demonstration device to be integrated, do as a whole, convenient carrying with preserve, during use, people's both hands contact respectively copper coin 6 and zine plate 7, reometer 3 deflects, and is easy to operate, vivid and interesting, help to attract visitor's interest, reach the effect of better popularizing science.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
