[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The purpose of the utility model is to provide a popular science interactive device for demonstrating the principle of the voltaic pile, so as to solve the problems existing in the prior art. During the design process, the inventor designs the metal component part to be rotatable on the premise of keeping the original basic model consistent with historical discoveries as much as possible, which is convenient for user interactive operation, improves the interactivity and interest of the popular science learning process to a certain extent, and ensures the integrity of the metal component part and the overall device, making the device easy to carry and maintain.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 4 As shown: This embodiment provides a popular science interactive device for demonstrating the principle of the voltaic battery stack, and the device includes: a battery stack box 1, a plurality of electrode groups 2 and a display lamp 3. Among them, the electrode group 2 is composed of two electrodes 4 that are bonded together, and the two electrodes 4 can be a round zinc sheet and a round copper sheet respectively. A rotating shaft rod 5 is provided on the battery stack box 1, and the electrode group 2 is fixed on the bracket 6. The electrode group 2 is connected to the rotating shaft rod 5 through the bracket 6 axis. In the battery stack box 1 on one side of the rotating shaft rod 5, a positive electrode 8 and a negative electrode 9 are respectively provided at both ends along the direction of the rotating shaft rod 5. A plurality of elastic material blocks 7 that can be impregnated with electrolyte are filled between the positive electrode 8 and the negative electrode 9. Every two adjacent elastic material blocks 7 are in contact with each other, and the positive electrode 8 and the negative electrode 9 are in contact with the adjacent elastic material blocks 7. The positive electrode 8 and the negative electrode 9 are respectively connected to the positive and negative poles of the display lamp 3 through the wire 15, and the display lamp 3 is preferably a light-emitting diode.

[0028] The electrode group 2 can be rotated along the rotating shaft 5 to between the corresponding two elastic material blocks 7, so that the two electrodes 4 of the electrode group 2 are respectively in contact with the two adjacent elastic material blocks 7, that is, it can also be rotated to a position away from the elastic material blocks 7. The elastic material block 7 that can be impregnated with electrolyte is preferably a sponge. Since the elastic material block 7 is elastic, the electrode group 2 can be inserted between the two elastic material blocks 7 and in close contact with the elastic material blocks 7 on both sides.

[0029] Based on the principle of the voltaic stack, the electrodes 4 located on both sides of the elastic material block 7 and in contact with it are two different metals, and the metal on one side has a stronger ability to lose electrons than the metal on the other side. Taking the zinc electrode and the copper electrode as an example, one end of the extended axis direction is defined as the left side, and the other end is defined as the right side. The electrode group 2 includes a left electrode 4 and a right electrode 4 that fit together. The right electrode 4 in the electrode group 2 located on the left side of a certain elastic material block 7 is a copper electrode, and the left electrode 4 in the electrode group 2 located on the right side of the elastic material block 7 is a zinc electrode. When the elastic material 7 block is impregnated with electrolyte, the copper electrode, the elastic material block and the zinc electrode form a voltaic cell, and electrons flow from the zinc electrode to the copper electrode. Correspondingly, a positive electrode 8 is set on the left side of the stack box 1, and a negative electrode 9 is set on the right side of the stack box 1. The left electrode 4 in each electrode group 2 in the present device can also be made of different metal materials, and the left electrode 4 can also be made of different metal materials, so as to ensure that the electron flow directions of the single voltaic cells formed on the left and right sides of the electrode group 2 are the same. Therefore, the relative positions of the positive electrode 8 and the negative electrode 9 in the figures are only examples and can be switched according to the direction of the formed voltaic current.

[0030] Through the popular science interactive device for displaying the principle of the voltaic pile provided by the above utility model, the user can realize the contact and separation of the electrode and the electrolyte by rotating the bracket during the experiment of the voltaic pile, and observe the on and off of the display light to understand the principle and phenomenon of the voltaic pile. Since multiple electrode groups are provided in this device, the user can also rotate multiple electrode groups respectively, observe the brightness difference of the display light, and then understand the qualitative relationship between the number of electrodes and the amount of electricity in the voltaic pile. The above design is convenient for user interactive operation, and improves the interactivity and fun of the popular science learning process to a certain extent. At the same time, the rotating design ensures the integrity of the metal electrode part and the overall device, making the device easy to carry and maintain.

[0031] In one embodiment of the utility model, the battery stack box 1 is divided into a first area and a second area, the rotating shaft rod 5 is arranged between the first area and the second area, and the elastic material block 7, the positive electrode 8 and the negative electrode 9 that can be impregnated with the electrolyte are arranged in the first area. The width of the first area and the second area (perpendicular to the direction of the rotating shaft rod 5) are both less than the length of the bracket 6, and the electrode group 2 can be rotated from the second area to the first area, so that a part of the electrode group 2 is placed in the first area and in contact with the elastic material block 7, or rotated from the first area to the second area, so that another part of the electrode group 2 is placed in the second area. Since the length of the bracket 6 is greater than the width of the first area and the second area, when the electrode group 2 is rotated to the first area or the second area, a part of the bracket 6 is located outside the edge of the battery stack box 1, so that the user can grab and lift the bracket 6 for rotation. The second area is used to place the electrode group 2, and the electrode group 2 located therein does not participate in the formation of the voltaic stack. When the user experiences it, the electrode group 2 placed in the second area can be rotated one by one to the first area, so that the electrode group 2 participates in the formation of the voltaic stack.

[0032] A limiting structure 11 is provided on the rotating shaft rod 5, and a convex groove 12 is provided on the inner wall of the battery stack box 1 at a position corresponding to the limiting structure 11. The limiting structure 11 and the convex groove 12 are used to respectively fasten the two ends of the elastic material block 7. There is a gap between two adjacent limiting structures 11 and between two adjacent convex grooves 12 to accommodate the bracket 6 and the electrode group 2.

After pouring the electrolyte into the battery stack box 1, part of the electrolyte is absorbed by the elastic material block 7, and the remaining electrolyte flows to the slit at one end along the inclined angle of the first bottom plate 16, and then is stored in the pull-out electrolyte box 10 located below. When the device is not in use, the pull-out electrolyte box 10 can be pulled out from the side of the battery stack box 1, and the electrolyte can be poured out, making the use and maintenance of the device more convenient. A second bottom plate 17 is provided in the second area of ​​the stack box 1 to support the electrode group 2 rotated to the second area.

[0034] In one embodiment, the popular science interactive device for displaying the principle of the voltaic pile further includes: a display panel 13, on which the pile box 1 and the display light 3 are arranged.
