Description
Technical Field
[0001] The utility model relates to the field of grounding, in particular to an electrostatic releaser. Background Art
[0002] The human body's electro-biochemical system contains countless electrical charges that constantly regulate biochemical reactions, including enzyme conversion, protein production, and pH control. As people use more and more electronic devices, the amount of electrical current they receive is also increasing.
[0003] Long-term, excessive electrical current can harm the human reproductive, nervous, and immune systems. It is a major cause of cardiovascular disease, diabetes, and cancer mutations, and a contributing factor to miscarriage and infertility in pregnant women. It also affects the development of tissues and bones in minors, causing vision and memory loss, and decreased liver function. Therefore, the human body must be effectively connected to the earth to regulate its electrical balance.
[0004] Currently, the primary method for connecting the human body to the earth is direct wire connection. This involves attaching a wire to a touchable part of the body, which then conducts current directly to the earth. This method cannot effectively maintain the body's internal electrical balance. Different people have different sensitivity to electricity. When the charge in the body accumulates to a certain level and then discharges, the current is directly discharged, causing pain and discomfort in some people. In certain situations, such as during thunderstorms when buildings are electrified, current can flow in the opposite direction through the grounding wire, affecting the body's electrical balance and even causing electric shock. Therefore, direct wire connection to the earth cannot maintain the body's internal electrical balance. Utility Model Content

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0023] An embodiment of the present application provides an electrostatic discharger comprising a guide metal connector, a grounding metal connector, and a regulation circuit.

[0024] In some embodiments, when the static electricity current generated in the environment is not very large, for example, static electricity is less generated in the summer, the resistance of the sliding rheostat can be adjusted to the maximum to prevent the current from flowing back; and when static electricity is easily generated in the environment, for example, in the winter when the weather is dry and frictional electrification is easy to occur, the resistance of the sliding rheostat can be adjusted to an adaptive position, that is, the electrical balance position of the human body, so that the static electricity can be smoothly released to the ground without causing discomfort to the human body.
[0025] Furthermore, when the static voltage is insufficient to provide an operating voltage for the smart load, the smart load stops operating and acts as a load, consuming current. The remaining current flows directly through the sliding rheostat and then to the ground via a grounded metal connector. Secondly, when the static voltage is excessive, current flows through the smart load, activating it. The sliding rheostat regulates the output current, smoothly discharging the static electricity to the ground. This makes the current imperceptible to the user, thus maintaining the body's bioelectrical balance. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the specific embodiments of the present invention.
[0036] Refer to the following Figures 1 to 3 , which is the preferred structure of an electrostatic releaser of the utility model.
[0037] like Figures 1 to 3 As shown, this embodiment provides an electrostatic discharger, including: a guide metal connector 1, a grounding metal connector 3 and a regulating circuit 2.
[0038] Specifically, the guide metal joint 1 is connected to the regulating circuit 2 through a wire to transfer current to the regulating circuit 2; the grounding metal joint 3 is connected to the regulating circuit 2 through a wire to conduct current from the regulating circuit 2 to the grounding metal joint 3; the regulating circuit 2 is provided with a sliding rheostat R5 and an intelligent load device, and the sliding rheostat R5 is provided with an A end, a B end and a P end. The intelligent load device is connected to the A end and the B end of the sliding rheostat R5, and the B end of the sliding rheostat R5 is also connected to the grounding metal joint 3, and the P end of the sliding rheostat R5 is connected to the guide metal joint 1.
[0039] The present invention provides an electrostatic discharger in an embodiment. The guide metal connector 1 is placed on the human body or an object that can be touched by the human body. The static electricity generated by the friction of electronic products or human clothing in a dry environment is transferred to the P end of the sliding rheostat R5 through the guide metal connector 1. The user can actively adjust the resistance of the sliding rheostat. When the static voltage is insufficient to provide the required operating voltage for the smart load device 21, the smart load device does not start and only consumes electricity as a load. Part of the static electricity is released to the ground through the sliding rheostat R5 and the grounded metal connector 3. Furthermore, when the static voltage absorbed by the guide metal connector 1 is too large, it can provide the operating voltage for the smart load device 21. The smart load device 21 starts working and cooperates with the sliding rheostat R5 to smoothly release the static electricity to the ground.
[0040] In another embodiment, when the grounding metal connector 3 comes into contact with abnormal current, the user adjusts the resistance of the sliding rheostat R5 to prevent excessive current from flowing back to the guide metal connector 1, thereby reducing damage to objects contacted by the guide metal connector 1 and maintaining the bioelectrical balance of the human body.
[0041] In some embodiments of the present invention, Figures 1 to 3 As shown, a fuse is installed between the B end of the sliding rheostat R5 of the regulating circuit 2 and the grounding metal connector 3, and the fuse F1 is a self-resetting fuse.
[0042] In the above embodiment, fuse F1 is a resettable fuse that automatically disconnects the circuit when an abnormal current flows through it, preventing current backflow. A resettable fuse is an overcurrent protection device that automatically disconnects the circuit when the current abnormally rises to a specific threshold and reconnects the circuit after the fuse's temperature returns to room temperature.
[0043] Among them, when current backflow occurs, that is, the current flows in the reverse direction, flowing back from the grounding metal connector 3 to the electrostatic induction metal connector, if the current is greater than the melting current of the fuse F1, the self-resetting fuse F1 will automatically disconnect, forming a circuit breaker, thereby preventing current backflow and maintaining the electrical balance of the human body.
[0044] It is understandable that the resettable fuse in the present technical solution is a preferred component. Among them, although the one-time fuse needs to be replaced after only one use, it also plays a role in preventing current backflow, so the above is also within the protection scope of the present utility model.
[0045] Alternatively, as Figures 2 to 3 As shown, the regulating circuit 2 is provided with a plurality of resistors.
[0046] In the above embodiment, the adjustment circuit 2 is provided with multiple resistors, including a first resistor R1, a second resistor R2, a third resistor R3 and a fourth resistor R4. The first resistor R1 is a 10KΩ resistor, the second resistor R2 is a 1KΩ resistor, the third resistor R3 is a 51Ω resistor, and the fourth resistor R4 is a 51KΩ resistor.
[0047] Among them, the first resistor is connected in series between the B end of the sliding rheostat and the fifth pin of the third single-chip microcomputer, the second resistor is connected in series between the third pin and the fourth pin of the third single-chip microcomputer, the third resistor is installed between the A end of the sliding rheostat and the eighth pin of the first single-chip microcomputer, and the fourth resistor is installed between the A end of the sliding rheostat and the sixth pin of the first single-chip microcomputer.
[0048] In the above embodiment, the first resistor R1 plays a current limiting role, ensuring that the current passing through the fuse F1 does not exceed its maximum fusing current, thereby protecting the circuit from overload damage.
[0049] The second resistor R2, third resistor R3, and fourth resistor R4 each perform different circuit functions. They are used for voltage division, current shunting, or providing a stable reference voltage for the microcontroller. The values of these resistors are selected based on the microcontroller's input / output characteristics and the required voltage / current levels to ensure stable circuit operation and signal accuracy.
[0050] In addition, these resistors can also be used in conjunction with certain specific pins of the microcontroller to implement specific circuit functions such as current detection, voltage division, etc.
[0051] It should be understood that this embodiment is not limited to the four resistors described above; this resistor group is merely a preferred design to limit the current in this design. Similarly, the number of resistor groups can be one, two, three, or more. As long as they can ensure stable current flow through fuse F1, these technical solutions do not deviate from the design concept and purpose of this utility model and are therefore within the scope of protection of this utility model.
[0052] Alternatively, as Figures 1 to 3 As shown, a plurality of single-chip microcomputers are provided in the intelligent load device 21 , and the single-chip microcomputers in the intelligent load device 21 are connected in a pin-to-point manner.
[0053] In the above embodiment, multiple single-chip microcomputers are provided in the intelligent load device 21. The connection between the single-chip microcomputers in the intelligent load device 21 is a pin-to-point connection. This design simplifies the wiring of the circuit, thereby reducing the risk of poor contact and improving the reliability of signal transmission. Figure 3 As shown, in this embodiment, only three single-chip microcomputers are provided, and the wiring of the three single-chip microcomputers can meet the logic set by the original program, that is, monitoring the circuit size and adjusting the size of the sliding resistor R5.
[0054] Among them, the second pin of the first single-chip microcomputer U1 is connected to the first pin of the second single-chip microcomputer U2, the sixth pin of the first single-chip microcomputer U1 is connected to the A end of the sliding potentiometer R5, the seventh pin of the first single-chip microcomputer U1 is connected in parallel with the seventh pin of the second single-chip microcomputer U2, the seventh pin of the third single-chip microcomputer U3 and the B end of the sliding resistor R5, the eighth pin of the first single-chip microcomputer U1 is connected to the A end of the sliding potentiometer R5, and the fifth pin of the first single-chip microcomputer U1 is connected to the eighth pin of the second single-chip microcomputer U2;
[0055] The second pin of the second single-chip microcomputer U2 is connected to the first pin of the third single-chip microcomputer U3, the fourth pin of the second single-chip microcomputer U2 is connected to the second pin of the third single-chip microcomputer U3, the fifth pin of the second single-chip microcomputer U2 is connected to the eighth pin of the third single-chip microcomputer U3, and the seventh pin of the second single-chip microcomputer U2 is connected to the seventh pin of the third single-chip microcomputer U3;
[0056] The third pin of the third single-chip microcomputer U3 is connected to the fourth pin of the third single-chip microcomputer U3 , and the fifth pin of the third single-chip microcomputer U3 is connected to the B end of the sliding resistor R5 .
[0057] It can be understood that the number of single-chip microcomputers can be one, two, three or more, and is not limited to the number mentioned; similarly, the pins between the single-chip microcomputers are not limited to the connection method described above. As long as the technical solution can monitor abnormal current and adjust the sliding resistor, it does not deviate from the design concept and purpose of the present invention, and is therefore within the scope of protection of the present invention.
[0058] Optionally, the sliding rheostat R5 is a manual sliding rheostat.
[0059] In the above embodiment, the sliding rheostat R5 is a manual sliding rheostat. During use, when the user does not need to discharge static electricity temporarily and also hopes to protect the control circuit or prevent the current from flowing back to the object contacted by the guide metal connector 1, the resistance value of the sliding rheostat R5 can be manually adjusted to further realize the function of the utility model.
[0060] Alternatively, as Figures 1 to 2 As shown, a fixing device is provided next to the grounding metal connector 3, and the fixing device includes a live wire pin 31 and a neutral wire pin 32. The metal connector and the fixing device form a three-prong plug.
[0061] In the above embodiment, a fixture is provided adjacent to the grounded metal connector 3. The fixture includes a live pin 31 and a neutral pin 32, and the metal connector and the fixture form a three-prong plug. The fixture provided adjacent to the grounded metal connector 3 not only provides additional stability and safety, but also, through its design, enhances the structural integrity of the plug. The fixture includes connectors specifically designed for the live and neutral wires, which, combined with the metal connector, form a three-prong plug. This design ensures a reliable and secure electrical connection.
[0062] Alternatively, as Figure 1 As shown, the fixing device provided above is made of insulating material.
[0063] In the above embodiment, the fixing device is made of an insulating material. This choice is primarily for electrical safety. When plugged into a three-hole socket, it only serves to fix the device, protecting the user from the risk of electric shock and ensuring the normal operation of the device without external interference.
[0064] It is understandable that the fixing device is also made of insulating materials such as ceramics and silicone, which can also achieve the purpose of the utility model itself, and is therefore also within the scope of protection of the present utility model.
[0065] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Therefore, any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
