Problems solved by technology

[0002] In the teaching of the lesson "Fast and Slow Dissolution" in the dissolution unit of the first volume of the fourth grade science textbook of the textbook version, when exploring the influence of temperature on the speed of dissolution and the influence of particle size on the speed of dissolution, if there is no If you don’t stir, it will take too long, and you won’t be able to complete the teaching task within the specified time. If you stir all the time, it will be difficult to ensure that the mixing speed and time of the two glasses of water are exactly the same, and the experimental results are not ideal.

Embodiment Construction

[0011] The structure diagram of the present invention is as figure 1 As shown, the agitator is mainly composed of a handle (1), a switch (2), a governor 2 (3), a motor 2 (4), a rotating shaft of the motor 2 (5), a stirring rod 2 (6), a power supply (7 ), a governor 1 (8), a connecting rod (9), a motor 1 (10), a rotating shaft (11) of the motor 1 and a stirring rod 1 (12). Wherein the switch (2) is mounted on the handle (1), the connecting rod (9) is a fixed rod with a slot in the middle, and the rotating shaft of the motor passes through the slot of the connecting rod, and the motor 1 (10) and the motor 2 ( 4) Both are fixed on the connecting rod (9) by adjustable screws. When adjusting the screws, the two motors can move left and right along the connecting rod (9), and the power supply (7), governor 1 (8) and speed regulator The governor 2 (3) is fixedly installed on the connecting rod and cannot be moved. The governor 1 (8) is connected with the motor 1 (10) to control and ...

Abstract

In order to demonstrate a dissolving experiment conveniently and quickly, the invention provides a stirrer and relates to a teaching and experimental instrument. The stirrer primarily comprises a handle, a power supply, a switch, a speed regulator, a motor, a stirring rod, a connecting rod and the like. The stirrer is low in cost, convenient to use and simple to operate. A user can adjust the position of the motor on the connecting rod according to the actual demand and select to close corresponding switching position, so that the motor drives one stirring rod to rotate to stir independently or two stirring rods to rotate to stir synchronously.

Description

technical field [0001] The invention relates to a teaching and experimental instrument, in particular to a stirrer in the teaching of dissolution experiments. Background technique [0002] In the teaching of the lesson "Fast and Slow Dissolution" in the dissolution unit of the first volume of the fourth grade science textbook of the textbook version, when exploring the influence of temperature on the speed of dissolution and the influence of particle size on the speed of dissolution, if there is no If it is not stirred, it will take too long and the teaching task cannot be completed within the specified time. If both are stirred, it is difficult to ensure that the mixing speed and time of the two glasses of water are exactly the same, and the experimental effect is not ideal. Contents of the invention [0003] In order to demonstrate the dissolution experiment conveniently and quickly, and overcome the above shortcomings, the present invention provides a stirrer, which rel...
