[0031] As mentioned in the background, when teachers teach advanced mathematics, they usually only use words or simple drawings on the blackboard to explain, which is often not intuitive enough and makes it difficult for students to understand quickly.

[0032] To solve this technical problem, this utility model provides a new teaching tool that is applied to teaching aids for higher mathematics.

[0033] For details, please refer to Figure 1 - Figure 3 The new teaching aids specifically include:

[0034] The liquid storage box 1 has an internal cavity filled with liquid;

[0035] Curved box 2 is located above liquid storage box 1. There are multiple curved box 2, which are arranged horizontally in parallel.

[0036] A connecting frame 3 is positioned between the liquid storage box 1 and the curved box 2. A flow channel 7 is provided inside the connecting frame 3 and at a position corresponding to each curved box 2. The curved box 2 is connected to the cavity inside the liquid storage box 1 through the flow channel 7.

[0037] Control button 4 is located on the side of the connecting frame 3. The control button 4 corresponds to the position of the flow channel 7. The number of control buttons 4 and the number of flow channels 7 are the same.

[0038] The label 5 is vertically positioned on the outer surface of the liquid storage box 1.

[0039] The novel teaching tool provided by this utility model, through the structural design of the liquid storage box 1, the curved box 2, the connecting frame 3, and the control button 4, enables the device to conduct the teaching process of definite integrals in advanced mathematics. Compared with writing on the blackboard, this device allows students to understand and learn more intuitively, effectively improving the teaching effect.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] Example 1:

[0042] Please refer to Figure 1 - Figure 3 A new type of teaching tool, comprising:

[0043] The liquid storage box 1 has an internal cavity filled with liquid. In this embodiment, the liquid is red to facilitate observation of the liquid flow. In other embodiments, the liquid may be any other color, which should also be within the scope of protection of this application.

[0044] Curved box 2 is located above liquid storage box 1. There are multiple curved box 2, which are arranged horizontally in parallel.

[0045] The connecting frame 3 is located between the liquid storage box 1 and the curved box 2. A flow channel 7 is provided inside the connecting frame 3 and at a position corresponding to each curved box 2. The curved box 2 is connected to the cavity inside the liquid storage box 1 through the flow channel 7. It can be seen that the flow channel 7 in the connecting frame 3 allows the liquid to flow back and forth between the liquid storage box 1 and the curved box 2. In order to facilitate the liquid to pass through the interior of the flow channel 7, the flow channel 7 is two symmetrically arranged funnels, and the smaller end of the flow channel 7 is the end closer to the control button 4.

[0046] Control button 4 is located on the side of the connecting frame 3. Control button 4 corresponds to the position of the flow channel 7. The number of control buttons 4 and the number of flow channels 7 are the same. It can be seen that the opening and closing of the flow channel 7 can be controlled by control button 4, thereby achieving the effect of stopping the flow.

[0047] The label 5 is vertically positioned on the outer surface of the liquid storage box 1 and is used to check the liquid volume inside the liquid storage box 1.

[0048] Through the above structural design, the device is fully sealed. The liquid is stored in the lower liquid storage box 1. When in use, the device is inverted to allow the liquid to flow into the curved box 2, and the control buttons 4 are turned off in sequence to keep the liquid inside the curved box 2. When teaching, the control buttons 4 are turned on in sequence to allow the liquid to flow into the liquid storage box 1 in sequence, thus showing the area of ​​the curved shape.

[0049] Example 2:

[0050] The novel teaching aids provided in Example 1 have been further optimized, specifically, as follows: Figures 3-5 As shown, a sliding groove is provided in the middle of the connecting frame 3, and the control button 4 is located inside the sliding groove. The control button 4 can slide laterally through the sliding groove. One end of the control button 4 extends to the outside of the connecting frame 3. A flow hole 8 is provided inside the control button 4 and near the end of the control button 4 located on the outside of the connecting frame 3. A groove 10 is provided at the other end of the control button 4, and a reset spring 9 is provided inside the groove 10.

[0051] Specifically, limit sliders 11 are fixedly connected to both sides of the control button 4. Limit grooves 12 are provided inside the connecting frame 3 at positions corresponding to the limit sliders 11. The limit sliders 11 are located inside the corresponding limit grooves 12. The limit sliders 11 and limit grooves 12 are slidably connected. Through the structural design of the limit sliders 11 and limit grooves 12, the movement of the control button 4 can be guided and limited, thereby effectively preventing the control button 4 from accidentally coming off.

[0052] Specifically, the groove 10 is fixedly connected inside the groove 10, and the positioning protrusion 13 is fixedly connected inside the middle slide groove of the connecting frame 3. One end of the reset spring 9 is sleeved on the outside of the positioning protrusion 13, and the other end of the reset spring 9 is sleeved on the outside of the positioning protrusion 24. By limiting the two ends of the reset spring 9 through the positioning protrusion 13 and the positioning protrusion 24, the reset spring 9 can be effectively prevented from tilting, thereby ensuring that the reset spring 9 resets the control button 4.

[0053] Specifically, sealing gaskets 15 are fixedly connected to both the upper and lower ends of the control button 4. The sealing gaskets 15 can effectively ensure the closing effect of the control button 4 on the flow channel 7.

[0054] With the above structural design, during use, pressing the control button 4 causes it to move into the connecting frame 3, allowing the flow channel 7 to connect through the flow hole 8, thus enabling the liquid to flow; releasing the control button 4 allows it to be reset by the force of the return spring 9, thereby separating the flow hole 8 from the flow channel 7, and thus blocking the flow channel 7 with the control button 4, achieving the effect of stopping the flow.

[0055] Example 3:

[0056] The novel teaching aids provided in Example 1 have been further optimized, specifically, as follows: Figure 1 As shown, a stabilizing frame 6 is provided on the outside of the liquid storage box 1, the curved box 2, and the connecting frame 3. The connecting frame 3 is fixedly connected to the stabilizing frame 6, and the stabilizing frame 6 is arranged in an I-shape.

[0057] The above structural design allows the device to be placed on a flat surface, and it can also be placed when the device is upside down.

[0058] Example 4:

[0059] The novel teaching aid provided in Example 1 is further optimized. Specifically, in order to facilitate viewing the liquid inside the liquid storage box 1 or the curved box 2, both the liquid storage box 1 and the curved box 2 are made of transparent material. Furthermore, the liquid storage box 1 and the curved box 2 are made of plexiglass.
