Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, specifically providing a human body static electricity discharge device and chip. Background Technology

[0002] Currently, in building and home settings, static electricity easily accumulates when clothing rubs against the body during movement. When a user touches a metal object, this static electricity is released instantly, causing significant pain and discomfort. If the user touches electronic devices, the high voltage generated by the instantaneous release of static electricity may even damage the devices.

[0003] In existing technology, electronic devices are equipped with independent electrostatic discharge balls, which are typically bare metal conductors directly grounded via wires.

[0053] Some embodiments of this application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of this application and are not intended to limit the scope of protection of this application.

The singular terms "a" or "this" can also include plural forms.

[0055] In existing technologies, when users use electrostatic discharge balls to release static electricity from their bodies, the discharge speed is extremely fast and the current peak is very high. Users can clearly feel the impact of the discharge moment, which can cause discomfort to the human body during the release of static electricity.

[0056] Based on this, in order to solve the above-mentioned technical problems, the technical concept of this application is to provide a new human body static electricity release device to achieve the imperceptible release of human body static electricity.

[0057] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0058] Figure 1 This is a schematic diagram of the structure of a human body static electricity release device according to an embodiment of this application. Figure 1 As shown, specifically, the human body static electricity release device includes: a housing 11, a touch unit 12, a touch detection module 13, a static electricity release module 14, a touch indicator module 15, and a control module 16.

[0059] In this embodiment, the housing 11 of the human body electrostatic discharge device is an electrostatic subconductor with a thickness of 2 mm and a resistivity between 10 and 10. 4 Ω·cm and 10 9 Between Ω·cm.

[0060] In this embodiment, the touch portion 12 is disposed on the side of the housing 11 for human touch to release static electricity.

[0061] The touch portion 12 includes an insulated inner ring 121 and an outer ring 122 made of an electrostatic subconductor, and the outer ring 122 is disposed around the inner ring 121 and is electrically connected to the electrostatic discharge module 14.

[0062] The inner ring 121 and the outer ring 122 are on the same plane, and the outer ring 122 can be the shell 11.

[0063] The touch detection module 13 is located below the touch part 12 and is connected to the control module 16. It is used to detect whether a human body touches the touch part 12.

[0064] The electrostatic discharge module 14 is connected to the outer ring 122 of the touch part 12 and is used to guide the static electricity of the human body to the ground.

[0065] In this embodiment, the touch indication module 15 is connected to the control module 16 and is used to provide an indication signal when the touch detection module 13 detects a human touch. After the user sees the indication signal, it is determined that the human body has come into contact with the human body static electricity discharge device, which indicates that the human body has begun to release static electricity.

[0066] In this embodiment, for example, the control module 16 can be a microcontroller. When the control module 16 receives the touch detection signal sent by the touch detection module 13, the control module 16 controls the touch indication module 15 to generate an indication signal.

[0067] In this embodiment, the indication signal can be sound, light, or vibration.

[0068] In this embodiment, when a user touches the touch portion 12 of the human body static electricity release device with their finger, the static electricity from the user's body is released to the ground through the electrostatic subconductor outer ring 122 of the touch portion 12 and the static electricity release module 14. Furthermore, since the resistivity of this electrostatic subconductor is between that of a conductor and an insulator, its controllable conductivity ensures that electrons can flow slowly and in a controlled manner within it, making the static electricity release process smooth and avoiding the generation of instantaneous large currents, thereby ensuring that the human body releases static electricity imperceptibly.

[0069] Figure 2 This is a schematic diagram of a second embodiment of a human body static electricity release device provided in this application. Based on the above embodiments, as follows... Figure 2As shown, specifically, the touch detection module 13 includes: touch pad 131 and touch signal generation module 132.

[0070] In this embodiment, the touch pad 131 is disposed on the back of the inner ring 121, and the touch pad 131 is electrically connected to the touch signal generation module 132.

[0071] In this embodiment, the touch signal generation module 132 includes a touch chip 133, a first resistor 134, a second resistor 135, a capacitor 136, and a first power supply 138.

[0072] The touch chip 133 can be a touch chip of model RH6030. The resistance of the first resistor 134 and the second resistor 135 is 1000Ω. The first power supply 138 is 3V.

[0073] In the touch signal generation module 132, the touch pad 131 is connected in series with the first resistor 134 and then connected to the touch input terminal of the touch chip 133; one end of the first capacitor 136 is connected to the touch input terminal of the touch chip 133; the other end of the first capacitor 136 is grounded; the ground terminal of the touch chip 133 is grounded; the output terminal of the touch chip 133 is connected in series with the second resistor 135 and then connected to the control module 16; the mode selection terminal of the touch chip 133 is left floating; the output level selection terminal of the touch chip 133 is left floating; the power supply terminal of the touch chip 133 is connected to the first power supply 138; and the second capacitor 148 is connected in parallel between the power supply terminal of the touch chip 133 and ground.

[0074] In this embodiment, the first capacitor 136 is a capacitor for adjusting touch sensitivity, and its adjustable range is 0pF to 50pF. Furthermore, the larger the capacitance value of the first capacitor 136, the lower the touch sensitivity. The first resistor 134 is used to improve the anti-interference capability of the touch pad 131. The second capacitor 148 can eliminate noise. Before the touch signal generation module 132 is powered on, a cover needs to be placed on the touch pad 131. When the touch chip 133 is powered on, it detects the environment and performs initialization. If the cover is placed after the touch chip 133 has initialized, the touch chip 133 will detect a sudden change in capacitance and cannot use it as the environment, thus causing misjudgment.

[0075] In this embodiment, since the mode selection terminal of the touch chip 133 is floating, the output terminal of the touch chip 133 outputs a high-level signal when touched, and outputs a low-level signal when the touch disappears. Because the output level selection terminal of the touch chip 133 is floating, the output terminal of the touch chip 133 only outputs a response when a touch is detected, and returns to its initial state when the touch disappears.

[0076] In this embodiment, the touch signal generation module 132 can generate accurate touch signals, thereby accurately indicating whether the user has touched the human body electrostatic discharge device.

[0077] Figure 3 This is a schematic diagram of a third embodiment of a human body static electricity release device provided in this application. Based on the above embodiments, as follows... Figure 3 As shown, specifically, the touch indicator module 15 includes: a third resistor 139, a fourth resistor 140, a light-emitting diode 141, a transistor 142, and a second power supply 143.

[0078] In this embodiment, the third resistor 139 has a resistance of 1000Ω. The fourth resistor 140 has a resistance of 400Ω. The second power supply 143 has a voltage of 3.3V. The transistor 142 can be an NPN transistor.

[0079] In this embodiment, one end of the third resistor 139 is connected to the control module 16; the other end of the third resistor 139 is connected to the base of the transistor 142; the emitter of the transistor 142 is grounded; the collector of the transistor 142 is connected to the negative terminal of the light-emitting diode 141; the positive terminal of the light-emitting diode 141 is connected to one end of the fourth resistor 140; and the other end of the fourth resistor 140 is connected to the second power supply 143.

[0080] In this embodiment, the second power supply 143 provides power to the entire circuit. The third resistor 139 is used to adjust the base current of the transistor 142, and by changing the resistance value of the third resistor 139, the conduction of the transistor 142 can be controlled. When the control module 16 outputs a high level to the touch indicator module 15, the transistor 142 conducts, thereby causing the light-emitting diode 141 to light up. When the control module 16 outputs a low level to the touch indicator module 15, the transistor 142 is cut off, the circuit containing the light-emitting diode 141 is disconnected, and the light-emitting diode 141 is turned off.

[0081] In this embodiment, the control module receives the user's touch signal, and after determining that the user has touched the human body static electricity release device, controls the light-emitting diode of the touch indicator module to light up, thereby reminding the user that they have successfully touched the human body static electricity release device and are releasing the static electricity of their body to the ground.

[0082] Figure 4 This is a schematic diagram of a fourth embodiment of a human body static electricity release device provided in this application. Based on the above embodiments, as follows... Figure 4 As shown, specifically, the electrostatic discharge module 14 includes: a grounded copper layer 144, a conductive connector 145, and a grounding wire 146 disposed on the circuit board.

[0083] In this embodiment, the outer ring 122 is connected to one end of the grounded copper layer 144 via a conductive connector 145; the other end of the grounded copper layer 144 is grounded via a grounding wire 146.

[0084] In this embodiment, the conductive connector 145 can be conductive foam. The outer ring 122 and the grounded copper layer 144 are connected by conductive foam. This conductive foam has low impedance and can quickly conduct static electricity into the grounding wire 146.

[0085] In this embodiment, the electrostatic discharge module 14 connects the outer ring 122 to the grounded copper layer 144 using low-impedance conductive foam to achieve rapid release of static electricity from the human body, thereby improving the efficiency of static electricity release.

[0086] Figure 5 This is a schematic diagram of the structure of a fifth embodiment of a human body static electricity release device provided in this application. Figure 5 As shown.

[0087] In this embodiment, the outer ring 122 and the conductive connector 145 are connected via a grounding terminal block 147. This grounding terminal block 147 ensures a secure connection between the outer ring 122 and the conductive connector 145, thereby guaranteeing the continuous effectiveness of the electrostatic discharge path.

[0088] When a human body touches the outer ring 122 of the touch part 12 of the human body static electricity discharge device, the static electricity of the human body passes through the outer ring 122 of the touch part 12, the grounding terminal block 147, the conductive connector 145, the grounding copper layer 144 and the grounding wire 146 in sequence, and conducts the static electricity of the human body to the ground.

[0089] When a person touches the outer ring 122 of the touch portion 12 of the electrostatic discharge device, and simultaneously touches the inner ring 121 of the touch portion 12, the output terminal of the touch signal generation module 132 outputs a high-level signal and transmits this high-level signal to the control module 16. Upon receiving this high-level signal, the control module 16 generates a high-level signal and sends it to the touch indicator module 15. Upon receiving the high-level signal, the transistor 142 of the touch indicator module 15 conducts, causing the light-emitting diode 141 in the touch indicator module 15 to illuminate, thus indicating that the user has touched the electrostatic discharge device and that electrostatic discharge has begun. If the user stops touching the touch portion 12 of the electrostatic discharge device, the output terminal of the touch signal generation module 132 outputs a low-level signal and transmits this low-level signal to the control module 16. After receiving the low-level signal, the control module 16 generates a low-level signal and sends it to the touch indicator module 15. After receiving the low-level signal, the transistor 142 of the touch indicator module 15 is turned off, and the circuit of the light-emitting diode 141 in the touch indicator module 15 is disconnected and stops emitting light. This indicates that the user has stopped touching the human body static electricity release device, that is, stopped releasing static electricity.

[0090] In this embodiment, when a user touches the human body static electricity release device, the static electricity of the human body can be quickly and imperceptibly released to the ground within a few seconds.

[0091] Accordingly, this embodiment also provides a human body electrostatic discharge chip, including the aforementioned human body electrostatic discharge device.
