Description
Technical field
The utility model relates to a kind of chemistry teaching instrument, specifically a kind of portable electrolyte demonstrating device.
Background technology
In high school chemistry teaching work, about the composition experiment of water is shown to student by Huffman electrolysis unit.So-called Huffman electrolysis unit is in a larger beaker, to insert two glass tubes, in the lower end of glass tube installing electrodes, and electrode pair should be connected to the two ends of battery, when injecting electrolytic solution in beaker, electrolytic solution forms loop between two electrodes, water electrolysis is become to hydrogen and oxygen, discharge by two glass tubes respectively.Because hydrogen and oxygen are all the gas of colorless and odorless, for directly perceived displaying in electrolytic process has hydrogen and oxygen to discharge, conventionally at the upper end of glass tube install combustion mouth, utilize the method for ignition to show have hydrogen and oxygen to discharge to student.But in this presentation process, need beaker and the glass tube used to be glassware, necessary extreme care in carrying and operating; Can be combustion-supporting due to hydrogen and oxygen, be still difficult to distinguish intuitively both characteristics.In addition, there is certain danger in burning hydrogen and oxygen, conventionally can only be operated by teacher, forbids that student operates, and reduced the interest of Students ' Learning.
Summary of the invention
The utility model for address the above problem provide a kind of rational in infrastructure, carry and portable electrolyte demonstrating device easy to use, safe, intuitive is strong.
The utility model for the technical scheme that technical solution problem adopts is:
Portable electrolyte demonstrating device described in the utility model comprises the packing case with handle, in the inner chamber of described packing case, be provided with electrolyte container, hydrogen tank, oxygen container, the lower end of described electrolyte container is provided with airtight battery compartment, in battery compartment, be provided with battery and magnetic switch, be embedded with permanent magnet in the position of the corresponding magnetic switch of the sidewall of packing case; Separately have the inner of two U-shaped pipes to be all inserted in electrolyte container, the outer end of two U-shaped pipes is inserted into respectively in hydrogen tank and oxygen container; The inner mouth of pipe place of two U-shaped pipes is respectively equipped with positive electrode and negative electrode, and described negative electrode is directly connected to the negative pole of battery by wire, and described positive electrode is connected to the positive pole of battery by magnetic switch.
In described electrolyte container, be installed with pilot lamp, described pilot lamp is connected on positive electrode between the positive pole of battery.
In described electrolyte container, be provided with installing plate, described installing plate is provided with the mounting hole and the leaking hole that run through installing plate plate body, and described U-shaped pipe is inserted in mounting hole.
Owing to having adopted said structure, this portable electrolyte demonstrating device is rational in infrastructure, carry with easy to use, safe, intuitive is strong.
Brief description of the drawings
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the electrical schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 1, portable electrolyte demonstrating device described in the utility model comprises the packing case 2 with handle 1, handle 1 is easy to carry and transport, the side hinged closures 13 of packing case 2, the inner side of cover plate 13 attaches the flexible materials such as sponge, the used time does not cover cover plate 13, and sponge can be fixed object wherein.
In the inner chamber of described packing case 2, be provided with electrolyte container 3, hydrogen tank 4, oxygen container 5, for ease of observing, these containers all adopt transparent glass or organic glass to make.The lower end of described electrolyte container 3 is provided with airtight battery compartment, in battery compartment, be provided with battery 6 and magnetic switch 7, position at the corresponding magnetic switch 7 of the sidewall of packing case 2 is embedded with permanent magnet 8, magnetic switch 7 adopts normally closed switch, in the time that magnetic switch 7 is positioned at permanent magnet 8 upper end magnetic switch 7 in open-circuit condition, when leaving, magnetic switch 7 is in closed circuit state, and the inner structure of magnetic switch 7 is known technology, does not do more descriptions at this.
Separately have the inner of two U-shaped pipes 11,12 to be all inserted in electrolyte container 3, the outer end of two U-shaped pipes is inserted into respectively in hydrogen tank 4 and oxygen container 5; The inner mouth of pipe place of two U-shaped pipes 11,12 is respectively equipped with positive electrode and negative electrode, and described negative electrode is directly connected to the negative pole of battery 6 by wire, and described positive electrode is connected to the positive pole of battery 6 by magnetic switch 7.
In addition, in described electrolyte container 3, be installed with pilot lamp 9, described pilot lamp 9 is connected on positive electrode between the positive pole of battery 6.
In described electrolyte container 3, be provided with installing plate 10, described installing plate 10 is provided with the mounting hole and the leaking hole that run through installing plate 10 plate bodys, and described U-shaped pipe is inserted in mounting hole.
When use, apparatus for demonstrating in packing case 2 is taken out, now magnetic switch 7 leaves the reach of permanent magnet 8, magnetic switch 7 closures, and positive electrode and negative electrode are charged, but when thering is no water in electrolyte container 3, can not form loop, and pilot lamp does not work.In electrolyte container 3, inject electrolytic solution, in hydrogen tank 4 and oxygen container 5, inject respectively the suds of different colours, as hydrogen tank 4 can be injected blue suds, in oxygen container 5, inject red suds; Now electrolytic solution is by positive electrode and negative electrode conducting, pilot lamp 9 is lighted, in indication circuit, there is electric current to pass through, oxygen and hydrogen that electrolysis produces inject respectively two U-shaped pipes 11,12, and be transported to respectively in hydrogen tank 4 and oxygen container 5 by U-shaped pipe, owing to containing suds in hydrogen tank 4 and oxygen container 5, the bubble producing forms colored soap bubble and emerges, simultaneously because the specific gravity difference of oxygen and hydrogen is larger, the soap bubble of hydrogen leaves the rear fast rise of hydrogen tank 4, and the soap bubble of oxygen can descend slowly and lightly downwards.The speed characteristic of showing two kinds of gas with various directly perceived that so just can rise by color and soap bubble, not only interesting but also ensured safety, flames of anger danger, can be by student's direct control.
After demonstration finishes, as long as apparatus for demonstrating is installed onto in packing case, magnetic switch 7 is disconnecting circuit under the effect of permanent magnet 8, and electrolytic reaction stops.
