[0026] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0027] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present application. The illustrations only show the components related to the present application rather than being drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0028] The specific implementation methods of the present application will be further described below in conjunction with the accompanying drawings. Embodiment 1

[0029] The present application embodiment discloses an induction hook light, referring to Figure 1 , Figure 2 and Figure 3 As shown, it includes a housing 1, a hook body 2, and a circuit module 3. The housing 1 is shaped like a "kangaroo", and the back of the housing 1 is attached to the wall by a colloid to fix the housing 1 on the wall.

[0030] The hook body 2 is mounted on the housing 1, and the circuit module 3 is located inside the housing 1 and connected to the hook body 2. Figure 3 and Figure 4 As shown, the circuit module 3 includes a weighing sensor 31, a microprocessor 32, a power supply module 33, a first signal light 34 and a second signal light 35. The power supply module 33 provides power to the circuit module 3. The power supply module 33 is powered by a lithium battery pack, which can provide a variety of required power voltages to meet the operation of the circuit components.

[0031] The weighing sensor 31 is used to sense the weight of the hanging object on the hook body 2 and feed back a first sensing signal. The microprocessor 32 is connected to the weighing sensor 31 to receive and process the first sensing signal. The first signal light 34 and the second signal light 35 are respectively arranged on the eyeball part of the shell 1 and are electrically connected to the microprocessor 32. When the first sensing signal is greater than the first threshold, the first signal light 34 is on; when the first sensing signal is greater than the second threshold, the second signal light 35 is on, and the second threshold is greater than the second threshold.

[0032] In this embodiment, the first threshold value and the second threshold value can be directly stored and set through the memory unit in the microprocessor 32. The microprocessor 32 can be a single chip microcomputer of various models. In this application, the weighing process is very intuitive and interesting through the first threshold value and the second threshold value. The first signal light 34 and the second signal light 35 are LED lamp beads, which have very low energy consumption and can be used for a long time.

[0033] The circuit module 3 is isolated and protected by the shell 1, so that the circuit module 3 is not exposed to the outside. At the same time, the weighing sensor 31 can detect and sense the hanging object. At this time, if the weight of the hanging object is relatively small, the first signal light 34 and the second signal light 35 will not light up. If the hanging object is between the first threshold value and the second threshold value, the first signal light 34 will light up. If the hanging object exceeds the second threshold value, the first signal light 34 and the second signal light 35 will light up at the same time. The first signal light 34 and the second signal light 35 are located in the eyeball part of the shell 1, so that the information feedback is not only timely and effective, but also interesting, so that the user can know the weight range of the hanging object in time to avoid overloading the hook. Embodiment 2

[0034] Based on the above embodiment, further optionally, refer to Figure 5 As shown, the microprocessor 32 is connected to a threshold adjustment unit 36, and the threshold adjustment unit 36 ​​includes a voltage source 361, a first potentiometer 362, a second potentiometer 363 and a current limiting resistor 364. The voltage source 361 is connected to one end of the resistor of the first potentiometer 362, the other end of the resistor of the first potentiometer 362 is connected to one end of the resistor of the second potentiometer 363, the other end of the resistor of the second potentiometer 363 is connected to one end of the current limiting resistor 364, the other end of the current limiting resistor 364 is grounded, the adjustment end of the first potentiometer 362 is connected to the microprocessor 32, and the adjustment end of the second potentiometer 363 is connected to the microprocessor 32.

[0035] In this embodiment, the voltage source 361 Vcc is 5V, and the first potentiometer 362 and the second potentiometer 363 are used to adjust the first threshold S1 and the second threshold S2 signals to the microprocessor 32. We know that the series resistor is used to divide the voltage output. Figure 5 In a specific example, the resistance range of Rp1 is (0-50 ohms), and similarly, the resistance range of Rp2 is (0-50 ohms) adjustable. The limit resistor is resistor R1, and the resistance is a fixed value of 10 ohms. At this time, the signal voltage value of S1 is U(S1)=5V×(Rp1+Rp2+10) / 110; the signal voltage value of S2 is U(S2)=5V×(Rp2+10) / 110. It can be seen that U(S1)>U(S2).

[0036] For the second embodiment of the threshold value adjustment unit 36, reference may be made to Figure 6As shown, the microprocessor 32 is connected to a threshold adjustment unit 36, and two adjustment units are provided. Each adjustment unit includes a voltage source 361, a first potentiometer 362 and a current limiting resistor 364. The voltage source 361 is connected to one end of the resistor of the first potentiometer 362, and the other end of the resistor of the first potentiometer 362 is connected to one end of the limiting resistor. The other end of the current limiting resistor 364 is grounded, and the adjustment end of the first potentiometer 362 outputs a voltage adjustment signal to the microprocessor 32. As can be seen from the circuit, the two adjustment units are independent of each other, so that the size of the threshold can be adjusted separately. This adjustment may make U (S1) smaller than U (S2), so this attention needs to be used when adjusting. In order to be able to adjust the size of the first threshold and the second threshold, so as to be suitable for different application environments, it can be adjusted through the first potentiometer 362 or the second potentiometer 363.

[0037] At the same time, the distance sensor 37 can also be used to sense and detect the approach of a human body, so that when a human body approaches, the weighing sensor 31 and the microprocessor 32 work, and the status of the first signal light 34 and the second signal light 35 inform the user; when the human body moves away, the energy consumption of the weighing sensor 31 and the microprocessor 32 can be reduced by disconnecting the circuit, so that the power supply module 33 can be used more durable. Embodiment 3

[0038] refer to Figure 7 As shown, the circuit module 3 also includes a distance sensor 37, and the distance sensor 37 is connected to a comparison circuit 38. The comparison circuit 38 outputs a start signal after determining that a human body is approaching. The output end of the comparison circuit 38 is also connected to a switch circuit 39. After receiving the start signal, the switch circuit 39 controls the power supply module to disconnect the power supply to the weighing sensor 31 and the microprocessor 32.

[0039] Specifically, the switch circuit 39 includes a transistor circuit 391 and a relay 392. The transistor circuit 391 controls the on and off of the coil of the relay 392. The normally open switch of the relay 392 is connected to the circuit of the power supply module 33. When the start signal is input into the transistor circuit 391, the normally open switch of the relay 392 is closed, and the weighing sensor 31 and the microprocessor 32 work; when a person moves away, the normally open switch of the relay 392 is reset, and the weighing sensor 31 and the microprocessor 32 stop working.

[0040] The comparison circuit 38 is mainly composed of a comparator LM1 and a peripheral circuit. The peripheral circuit is a number of resistors. When the distance sensor senses that a human body is approaching, the comparator LM1 outputs a high level signal. Then it is transmitted to the switch circuit 39. The transistor circuit 391 is mainly composed of a transistor Q1, resistors R11 and R12. When the high level is transmitted to the base of the transistor Q1 through the resistor R11, the transistor Q1 works in a conducting state, so that the coil part K1 of the relay 392 is energized, so that the relay 392 is actuated, and the normally open switch of the relay 392 is closed, so that the power supply module 33 provides power to the load. The load here refers to the microprocessor 32 and the weighing sensor 31. The weighing sensor 31 also requires a working voltage to work normally. The switch part of the relay can be a multi-way switch, so that the power supply lines of the microprocessor and the weighing sensor can be controlled separately.

[0041] Other technical improvements are that, further, on the basis of the above embodiments, it can be further refined, and there are other implementations. For example, optionally, the shell 1 is provided with ear protrusions 4, the ear protrusions 4 are provided with air holes 5, a clamping plate 6 is provided inside the shell 1, and a scented sheet 7 is placed on the clamping plate 6, and the scented sheet 7 emits fragrance through the air holes 5. The scented sheet 7 can be purchased on the market with any fragrance.

[0042] The temperature generated by the operation of the circuit module 3 can also be used to increase the volatilization of the aroma of the scent sheet 7, so that the aroma can increase the environmental comfort of the user.

[0043] The above embodiments are only illustrative of the principles and effects of the present application, and are not intended to limit the present application. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be included in the protection scope of the present application.
