[0045] See also Figure 1 The utility model provides a teaching aid of TCM Five Elements Theory, comprising at least two sockets 1 and a plurality of plug-in objects 2, each socket 1 having at least one plug-in interface 11, each plug-in object 2 having an identification unit, and the plug-in object 2 can be inserted into the plug-in interface 11, each socket 1 having a vertical classification character mark of TCM Five Elements Theory, and each plug-in object 2 having a horizontal classification character mark of TCM Five Elements Theory, so that in the process of in-class demonstration and teaching, the teacher can plug the plug-in object 2 into the matching socket 1 in a way of building blocks, so as to explain the relationship between the various elements in TCM Five Elements Theory in a more vivid and concrete way, thereby facilitating students' memory.

[0046] The recognition unit is configured to determine whether the horizontal classification character identification on the connector 2 matches the vertical classification character identification on the socket 1 after the connector 2 is inserted into the socket 11, so that when testing the students' knowledge mastery, timely feedback can be given on whether the connector 2 is plugged into the correct socket 1, thereby testing the students' knowledge mastery and promptly reminding students of memory errors.

[0047] Specifically, the vertical classification character identifier includes any one of the five tones, five flavors, five colors, five transformations, five qi, five directions, five seasons, five elements, five internal organs, six bowels, five sense organs, body shape, emotions, five sounds and changes, as shown in Table 1, where the five tones include: Jiao, Zheng, Gong, Shang and Yu; the five flavors include: sour, bitter, sweet, pungent and salty; the five colors include: green, red, yellow, white and black; the five transformations include: birth, growth, transformation, collection and storage; the five qi include: wind, heat, humidity, dryness and cold; the five directions include: The five directions are: east, south, center, west and north; the five seasons are: spring, summer, long summer, autumn and winter; the five elements are: wood, fire, earth, metal and water; the five internal organs are: liver, heart, spleen, lungs and kidneys; the six internal organs are: gallbladder, small intestine, stomach, large intestine and bladder; the five sense organs are: eyes, tongue, mouth, nose and ears; the body is: tendons, veins, flesh, skin and bones; emotions are: anger, joy, thought, sadness and fear; the five sounds are: call, laugh, sing, cry and groan; changes are: grip, worry, hiccup, cough and chestnut.

[0049]

[0050] Table 1

[0051] Specifically, taking the five internal organs as an example of the vertical classification character identification on the socket 1, five sockets 1 need to be set up, and the vertical classification character identifications on the five sockets 1 are liver, heart, spleen, lung and kidney respectively. Based on this, each plug-in object 2 needs to be set with a character identification other than liver, heart, spleen, lung and kidney. During the in-class demonstration and explanation, the teacher needs to plug the plug-in object 2 into the correct socket 1. For example, plug the plug-in object 2 with the vertical classification character identification of gallbladder, horn, sour, green, life, wind, east, spring, wood, gallbladder, eyes, tendons, anger, call and grasp into the socket 1, so as to visualize the abstract text, thereby facilitating students' memory and improving the efficiency and accuracy of memory.

[0052] Furthermore, the socket 1 includes a socket shell 12 and a socket electrode 13. The socket shell 12 is provided with a longitudinal classification character mark and coated with an identification coating matching the longitudinal classification character mark. It can be understood that the identification coating should be coated on the socket shell 12 first and then the longitudinal classification character mark should be set on the identification coating, and the color of the longitudinal classification character mark should be inconsistent with the color of the identification coating to facilitate reading of the longitudinal classification character mark. For example, the colors of the identification coatings corresponding to the five sockets 1 with longitudinal classification character marks of liver, heart, spleen, lung and kidney can be set to cyan, red, yellow, white and black respectively. The color of the longitudinal classification character mark set on the socket 1 with cyan, red, yellow and white colors can be black, and the color of the longitudinal classification character mark set on the socket 1 with black color can be white, and a plurality of sockets 11 (for example, 14) are formed on the socket shell 12, and each socket 11 is provided with a socket electrode 13.

[0053] The plug-in object 2 is correspondingly configured to include a plug-in shell 21, an identification lamp 22 and a connecting electrode 23. A housing cavity suitable for accommodating the identification lamp 22 is formed in the plug-in shell 21, and a plug-in rod structure matching the plug-in interface 11 is formed on the plug-in shell 21. The connecting electrode 23 is arranged on the plug-in rod structure and can contact the socket electrode 13. The socket electrode 13 is connected to a power source, and the connecting electrode 23 is also electrically connected to the identification lamp 22. When the connecting electrode 23 contacts the socket electrode 13, the identification lamp 22 is powered on and emits light, and the color of the light emitted by the identification lamp 22 in the plug-in object 2 matching the socket 1 matches the color of the identification coating of the socket 1. For example, the identification light 22 in the connector 2 whose vertical classification character logo matches the liver can emit cyan light, the identification light 22 in the connector 2 whose vertical classification character logo matches the heart can emit red light, the identification light 22 in the connector 2 whose vertical classification character logo matches the spleen can emit yellow light, the identification light 22 in the connector 2 whose vertical classification character logo matches the lungs can emit white light, and the identification light 22 in the connector 2 whose vertical classification character logo matches the kidneys can emit purple light (it can be understood that since there is no black light, darker purple light can be used as a color that matches black).

[0054] In addition, it should be noted that the plug-in housing 21 of each plug-in object 2 can be made of light-transmissive white plastic to ensure that each plug-in object 2 has no other differences except the vertical classification character identification, so as to prevent students from cheating when testing them.

[0055] Furthermore, the plug-in object 2 also includes a storage medium 24 and an audio playback device 25, both of which are arranged in the plug-in shell 21, and the storage medium 24 is preset with explanation content matching the horizontal classification character logo of the plug-in object 2, and the storage medium 24 is electrically connected to the connecting electrode 23 and the audio playback device 25, and the audio playback device 25 is suitable for playing the explanation content.

[0056] Taking the insert 2 with the horizontal classification character logo of gallbladder as an example, its storage medium 24 stores words explaining the physiological function characteristics of the gallbladder, for example: the gallbladder can store and excrete bile, bile is an important substance for digesting fat, the gallbladder can store bile and release it when needed to promote the digestion and absorption of fat; the gallbladder can regulate emotions and thinking activities, the gallbladder meridian is related to emotions, the gallbladder is responsible for decision-making, courage and self-confidence, and is also related to emotions such as anger and irritability. The gallbladder meridian maintains the mental health of the human body by regulating the balance of emotions and thinking activities.

[0057] Furthermore, a pair of stop plates 111 may be provided on the inner wall of the plug interface 11, and a through-hole suitable for the plug rod structure to pass through is formed between the relatively arranged stop plates 111. An elastic member 14 (such as a coil spring) is also provided between the bottom wall of the plug interface 11 and the stop plate 111. A pair of axial limit protrusions 26 are provided on the plug rod structure. The axial limit protrusions 26 can pass through the through-hole and abut against the elastic member 14. The plug rod structure can rotate in the plug interface 11. The axial limit protrusion 26 can rotate between the stop plate 111 and the elastic member 14. The elastic member 14 can apply a force toward the stop plate 111 to the axial limit protrusion 26. At least one rotation limit protrusion 15 is also provided on the inner wall of the plug interface 11. The rotation limit protrusion 15 is arranged between the stop plate 111 and the elastic member 14, and the axial limit protrusion 26 can abut against the rotation limit protrusion 15.

[0058] When plugging and installing the plug-in object 2, the plug-in rod structure is now inserted into the plug-in port 11, so that the axial limit protrusion 26 passes through the penetration opening and abuts against the elastic member 14, and then the insertion is continued until the plug-in rod structure can rotate in the plug-in port 11, and then the plug-in object 2 is rotated until the axial limit protrusion 26 is stopped by the rotation limit protrusion 15, indicating that the plug-in object 2 is rotated into place, and finally the axial limit protrusion 26 is released so that the axial limit protrusion 26 abuts between the elastic member 14 and the stop sheet 111 under the action of the elastic member 14, thereby ensuring that the plug-in object 2 is not easy to fall out of the plug-in port 11, and this installation method is simpler and more time-saving.

[0059] In addition, it can be understood that the socket electrode 13 can be arranged on the side of the stop plate 111 that abuts the axial limit protrusion 26, and the connecting electrode 23 can be arranged on the side of the axial limit protrusion 26 that abuts the stop plate 111 to ensure stable contact between the electrodes and prevent poor contact. An on-off switch 27 can be arranged on the plug-in object 2, and the storage medium 24 and the audio playback device 25 are connected in series to form a playback unit, and the playback unit and the identification light 22 are connected in parallel to form a functional unit, and the functional unit is connected in series with the on-off switch 27, so that when the on-off switch 27 is disconnected, the audio playback device 25 and the identification light 22 are not powered on, which can ensure the safety of the plug-in process, and when the on-off switch is disconnected, the audio playback device 25 and the identification light 22 are powered on to achieve the above-mentioned related functions.

[0060] Furthermore, the socket 1 can be set to a spherical shape, and the plug-in ports 11 are evenly distributed on the surface of the socket 1, so that the socket 1 can be smaller in size and can be plugged with more plug-in objects 2. The utility model provides a teaching aid for the theory of the five elements of traditional Chinese medicine that can also include a base 3 and a rotating frame 4. Specifically, the base 3 includes a support seat 31 and a telescopic column 32. One end of the telescopic column 32 is connected to the support seat 31, and the other end is connected to the rotating frame 4, so as to drive the rotating frame 4 to rise and fall when the telescopic column 32 is extended and retracted. The socket 1 is arranged on the rotating frame 4, and the rope of the telescopic column 32 can drive the socket 1 to rise and fall to a suitable position for display, and the rotating frame 4 can be rotated to rotate the socket 1 to be displayed to the side facing the students for display, or to facilitate the insertion of the plug-in object 2 on the corresponding socket 1. In addition, it can be understood that a universal wheel (not shown in the figure) can be set at the bottom of the support seat 31 to drive the entire teaching aid of the theory of the five elements of traditional Chinese medicine to move.

[0061] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments.
