Description

Technical Field

[0001] This utility model belongs to the field of demonstration teaching aids technology, and relates to a device that can be used to demonstrate various types of inductive switches. Background Technology

[0002] Currently, elementary school students begin introductory teaching of electricity. Circuit teaching aids, physical objects intended for disseminating technology and educating people, are indispensable equipment in students' science and technology education. To facilitate students' intuitive understanding of switch control circuits, and with the advancement of technology, many types of sensor switches have emerged, such as light-sensitive switches, touch-sensitive switches, hand-scanning switches, human body-sensing switches, wireless remote control switches, touch-dimmer switches, and voice-activated switches. An existing circuit teaching aid with good demonstration effects (application number: 201920308156.4) mainly includes a battery, a light bulb, and a single-pole switch. Students understand how a single-pole switch controls the light bulb's on and off by observing the closing and opening of the switch. However, this teaching aid only allows students to experience the control method of a simple switch; students cannot experience various sensor switches, making it difficult to overcome the teaching difficulties. Therefore, improving existing demonstration teaching aids and designing a new multi-functional control switch demonstrator to overcome the above-mentioned technical shortcomings and improve the overall practicality of switch demonstration teaching aids is particularly important. Utility Model Content

[0003] This invention provides a sensor switch demonstrator to solve the problem that existing teaching aids offer a limited teaching experience with switches.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: It includes a main box and a secondary box. The main box is equipped with a battery, an LED light, a first neodymium magnet, a second neodymium magnet, and a third neodymium magnet. The positive terminal of the LED light is connected to the positive terminal of the battery via a wire, and the negative terminal of the LED light is connected to the third neodymium magnet via a wire. The first neodymium magnet is connected to the positive terminal of the battery via a wire, and the second neodymium magnet is connected to the negative terminal of the battery via a wire. The secondary box is equipped with a sensor. The system comprises a first neodymium magnet, a second neodymium magnet, and a third neodymium magnet in a secondary box. The positive input terminal of the sensor is connected to the first neodymium magnet in the secondary box via a wire, the negative input terminal of the sensor is connected to the second neodymium magnet in the secondary box via a wire, and the negative output terminal of the sensor is connected to the third neodymium magnet in the secondary box via a wire. The first neodymium magnet in the secondary box can be attracted to the first neodymium magnet in the main box, the second neodymium magnet in the secondary box can be attracted to the second neodymium magnet in the main box, and the third neodymium magnet in the secondary box can be attracted to the third neodymium magnet in the main box.

[0005] In the above technical solution, a more specific technical solution may be: the distance between the first neodymium magnet in the main box and the second neodymium magnet in the main box is greater than the distance between the second neodymium magnet in the main box and the third neodymium magnet in the main box, and the distance between the first neodymium magnet in the secondary box and the second neodymium magnet in the secondary box is greater than the distance between the second neodymium magnet in the secondary box and the third neodymium magnet in the secondary box.

[0006] Furthermore: the N pole of the first neodymium magnet in the main box faces outward, the S pole of the second neodymium magnet in the main box faces outward, the S pole of the third neodymium magnet in the main box faces outward, the S pole of the first neodymium magnet in the auxiliary box faces outward, the N pole of the second neodymium magnet in the auxiliary box faces outward, and the N pole of the third neodymium magnet in the auxiliary box faces outward, ensuring that the auxiliary box cannot be attracted to the main box when placed upside down.

[0007] Furthermore, a power switch is provided between the first neodymium magnet in the main box and the battery, and the power switch is used to connect and disconnect the power supply to the battery.

[0008] Furthermore, the sensor is one of the following: a light sensor switch, a touch sensor switch, a hand-scan sensor switch, a human body sensor switch, a wireless remote control switch, a touch dimming switch, or a voice-activated sensor switch.

[0009] Furthermore: the main box body is also provided with a main box cover, the main box cover is provided with multiple main cover tenons, the main box body is provided with a main box mortise that matches the main cover tenons, and the main box cover and the main box body are connected by a mortise and tenon structure, which is convenient for disassembly and assembly.

[0010] Furthermore, the secondary box body is also provided with a secondary box cover, the secondary box cover has multiple secondary box cover tenons, and the secondary box body has secondary box mortises that are adapted to the secondary box cover tenons. The secondary box cover and the secondary box body are connected by a mortise and tenon structure for easy assembly and disassembly. The secondary box cover has three through holes, and the first neodymium magnet, the second neodymium magnet, and the third neodymium magnet of the secondary box are respectively fixed in the three through holes by hot melt adhesive to prevent the first neodymium magnet, the second neodymium magnet, and the third neodymium magnet of the secondary box from being attracted out and detached by the first neodymium magnet, the second neodymium magnet, and the third neodymium magnet of the main box.

[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: the secondary box is attracted to the main box's first, second, and third neodymium magnets via the secondary box's first, second, and third neodymium magnets. The battery powers the sensor, and when the sensor is triggered, the LED light and battery are connected, and the LED light starts to work. By replacing various sensors, it is convenient for teachers to conduct teaching, and students can personally experience the control methods of various switches, improving the quality of teaching and ensuring that students can better learn about various types of sensor switches.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and examples:

[0022] like Figures 1 to 8The illustrated inductive switch demonstrator includes a main housing 1 and a secondary housing 2. The main housing 1 houses a battery 11, an LED light 12, a first neodymium magnet 14, a second neodymium magnet 15, and a third neodymium magnet 16. The positive terminal of the LED light 12 is connected to the positive terminal of the battery 11 via a wire, and the negative terminal of the LED light 12 is connected to the third neodymium magnet 16 via a wire. The first neodymium magnet 14 is connected to the positive terminal of the battery 11 via a wire, and the second neodymium magnet 15 is connected to the negative terminal of the battery 11 via a wire. The secondary housing 2 houses a sensor 21, a secondary... The main box has a first neodymium magnet 22, a second neodymium magnet 23, and a third neodymium magnet 24. The positive input terminal of the sensor 21 is connected to the first neodymium magnet 22 of the secondary box via a wire, the negative input terminal of the sensor 21 is connected to the second neodymium magnet 23 of the secondary box via a wire, and the negative output terminal of the sensor 21 is connected to the third neodymium magnet 24 of the secondary box via a wire. The first neodymium magnet 22 of the secondary box can be attracted to the first neodymium magnet 14 of the main box, the second neodymium magnet 23 of the secondary box can be attracted to the second neodymium magnet 15 of the main box, and the third neodymium magnet 24 of the secondary box can be attracted to the third neodymium magnet 16 of the main box. The distance between the first neodymium magnet 14 and the second neodymium magnet 15 in the main box is greater than the distance between the second neodymium magnet 15 and the third neodymium magnet 16 in the main box. The distance between the first neodymium magnet 22 and the second neodymium magnet 23 in the secondary box is greater than the distance between the second neodymium magnet 22 and the third neodymium magnet 33 in the secondary box. This results in the first neodymium magnet 14, the second neodymium magnet 15, and the third neodymium magnet 16 in the main box being unequally spaced, and the first neodymium magnet 22, the second neodymium magnet 23, and the third neodymium magnet 24 in the secondary box being unequally spaced. The N-pole of the first neodymium magnet 14 in the main box faces outwards, as do the S-pole of the second neodymium magnet 15 and the third neodymium magnet 16 in the main box. Similarly, the S-pole of the first neodymium magnet 22 in the auxiliary box faces outwards, as do the N-pole of the second neodymium magnet 23 and the third neodymium magnet 24 in the auxiliary box. If the auxiliary box 2 is inverted and attempts to attach to the main box 1, according to the principle of magnetism (like poles repel, unlike poles attract), the third neodymium magnet 24 cannot attract the first neodymium magnet 14, and the first neodymium magnet 22 cannot attract the third neodymium magnet 16. This ensures that the auxiliary box 2, when inverted, cannot attach to the main box 1. A power switch 13 is provided between the first neodymium magnet 14 in the main box and the battery 11. The power switch 13 is used to connect and disconnect the power supply to the battery 11. Sensor 21 is one of the following: light sensor switch, touch sensor switch, hand-scan sensor switch, human body sensor switch, wireless remote control switch, touch dimming switch, or voice-activated sensor switch. In this example, sensor 21 is a human body sensor switch. The main box body 1 is also provided with a main box cover 17. The main box cover 17 has multiple main cover tenons 19. The main box body 1 has a main box mortise 18 that matches the main cover tenons 19. The main box cover 17 and the main box body 1 are connected by a mortise and tenon structure for easy assembly and disassembly.The secondary box body 2 is also provided with a secondary box cover 25. The secondary box cover 25 has multiple secondary cover tenons 28. The secondary box body 2 has secondary box mortises 27 that are adapted to the secondary cover tenons 28. The secondary box cover 25 and the secondary box body 2 are connected by a mortise and tenon structure for easy disassembly and assembly. The secondary box cover 25 has three through holes 26. The distance between the three through holes 26 is the same as the distance between the first neodymium magnet 14, the second neodymium magnet 15, and the third neodymium magnet 16 of the main box. The first neodymium magnet 22, the second neodymium magnet 23, and the third neodymium magnet 24 of the secondary box are fixed in the three through holes 26 by hot melt adhesive to prevent the first neodymium magnet 22, the second neodymium magnet 23, and the third neodymium magnet 24 of the secondary box from being attracted out by the first neodymium magnet 14, the second neodymium magnet 15, and the third neodymium magnet 16 of the main box.

[0023] When in use, attach the auxiliary box 2 equipped with the human body sensor switch to the main box 1, turn on the power switch 13, and when a student walks by, the human body sensor switch will detect the human body and the LED light 12 will light up, allowing the student to personally experience the control method of the human body sensor switch.

[0024] It should be noted that the sensor 21 provided by this utility model is a common device in the prior art. Light sensor switches, touch sensor switches, hand sweep sensor switches, human body sensor switches, wireless sensor switches and voice-controlled sensor switches can all be purchased directly. The technical solution of this utility model can be obtained simply by connecting the sensor 21 and the LED light 12 through the connection relationship given in the embodiment of this utility model.
