The utility model relates to an interesting electrolyte conductivity experiment demonstration instrument used in chemical experiment teaching, which comprises an electrode (1), an electrolyte solution storage tank (3), a blower (6), a blowing cylinder (7), a light emitting diode (8) and a suspension ball (9). The utility model is characterized in that the blower (6) is fixed on the electrolyte solution storage tank (3), and is sealed connected with the blowing cylinder (7). The serial-connected light emitting diode and blower are connected with the circuit. The electrolyte solution is conductive, the suspension ball is upward floating and the light emitting diode is lighting after the communication of the power supply. The utility model has simple and clear circuit, vivid and interesting phenomenon of the demonstration, and safe operation.
Description
Technical field: the utility model relates to the entertaining electrolytic conductivity experimental demonstration instrument that a kind of chemical experiment teaching is used.
Background technology: in the existing chemical experiment teaching, the device that is used for the electrolytic conductivity experimental demonstration generally adopts bulb as display device, and the experimental technique phenomenon is more stiff like this, and poor stability.
Summary of the invention: the purpose of this utility model is to provide a kind of entertaining electrolytic conductivity experimental demonstration instrument of handling safety.
The purpose of this utility model is achieved in that entertaining electrolytic conductivity experimental demonstration instrument is made up of electrode (1), electrode (2), electrolyte solution storage tank (3), white binding post (4), black binding post (5), fan blower (6), air blast tube (7), light emitting diode (8), suspension ball (9) and air inlet (10); It is characterized in that: the positive pole of light emitting diode (8) is linked to each other with positive source, and the negative pole of light emitting diode (8) is connected on the black binding post (5) of fan blower (6), and black binding post (5) is also connecting the upper end of electrode (1) simultaneously; The white binding post (4) of fan blower (6) is connected with the upper end of power cathode with electrode (2); The lower end of fan blower (6) is left air inlet (10) and is fixed on the suitable for reading of electrolyte solution storage tank (3), and the upper end of fan blower (6) and air blast tube (7) are with the air-tight manner socket, and a suspension ball (9) is put in air blast tube (7) upper end.
Advantage of the present utility model is: light emitting diode (8) and suspension ball (9) as the electric conductivity display device, have been strengthened vividness, the interest of lecture experiment, and used low-tension supply, strengthened the security of experimental implementation.
Description of drawings: the drawing of accompanying drawing (1) is described as follows:
Figure (1) is the front view (FV) of the utility model entertaining electrolytic conductivity experimental demonstration instrument.
Being described as follows of each label among the figure:
Electrode-1, electrode-2, electrolyte solution storage tank-3, white binding post-4, black binding post-5, fan blower-6, air blast tube-7, light emitting diode-8, suspension ball-9, air inlet-10.
Embodiment: be described in detail embodiment of the present utility model in conjunction with the accompanying drawings:
Link to each other with positive source referring to the positive pole of accompanying drawing (1) with light emitting diode (8), the negative pole of light emitting diode (8) links to each other with the upper end of electrode (1) and the black binding post (5) of fan blower (6); The white binding post (4) of fan blower (6) is connected with the upper end of power cathode with electrode (2), thus with light emitting diode (8) and fan blower (6) with the series system place in circuit; The lower port of fan blower (6) is fixed on the suitable for reading of electrolyte solution storage tank (3), and leaves air inlet (10), and the upper end of fan blower (6) and air blast tube (7) closely connect together with air-tight manner; A suspension ball (9) is put in air blast tube (7) upper end, and the lower end of suspension ball (9) contacts in tangent mode with surrounding, air blast tube (7) upper end.Because with light emitting diode (8) and fan blower (6) series connection place in circuit, when in electrode (1) and (2) insertion electrolyte solution, ionic conduction, power connection, ball float (9) floats, light emitting diode (8) is luminous, the lively entertaining of demonstrative process, and handling safety, circuit is simple and clear.
