Description

Technical Field

[0001] This utility model relates to the field of electrostatic monitoring and protection technology, and in particular to an antistatic chair that can monitor static electricity and provide audible and visual alarms. Background Technology

[0002] As people's demands for comfort and safety in their work and living environments continue to increase, the functions of chairs are also constantly expanding and improving. In certain work scenarios, such as electronic equipment manufacturing workshops and laboratories, static electricity has become a significant factor affecting production quality and personnel safety. The accumulation of static electricity can damage precision electronic equipment and cause safety accidents; therefore, the anti-static performance of chairs is receiving increasing attention. Related technological advancements are dedicated to improving the anti-static capabilities of chairs to ensure a safe and stable production environment and reduce losses caused by static electricity.

[0003] In existing technologies, several common methods exist for addressing the anti-static issue in chairs. One method involves using anti-static materials to manufacture the chairs. These materials possess inherent conductivity, allowing static electricity to dissipate through their natural properties. Another method is installing a grounding wire at the bottom of the chair, conducting static electricity to the ground to eliminate it. Additionally, external devices such as ionizers are used to eliminate static electricity. Ionizers generate positive and negative ions to neutralize static charges in the air. These methods effectively address the anti-static problem in chairs to some extent and are widely used in various scenarios.

[0004] However, existing technologies have significant drawbacks. These common anti-static methods cannot monitor static electricity in real time, and their anti-static effect is passive and unstable. For example, anti-static materials may fail after long-term use and cannot continuously and effectively release static electricity; the installation of grounding wires is relatively complex and restricts the mobility of the chair, greatly limiting the applicable scenarios; ion fans are bulky and energy-intensive, not only taking up space but also increasing operating costs.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] This utility model discloses an anti-static chair that can monitor static electricity and provide audible and visual alarms, such as... Figures 1 to 3 As shown, the device includes a chair body 1 and a static electricity elimination and detection device 2. The static electricity elimination and detection device 2 is installed on the chair body 1, and its specific location can be set in various parts such as the backrest and armrests. The two are fixed by a double-layer buckle, which enables the chair to have static electricity monitoring, elimination and alarm functions, and the device is stably fixed in a vibration environment. This is because the double-layer buckle can effectively resist vibration and ensure that the device is firmly connected to the chair body 1. The integrated device can realize static electricity related functions.

[0026] Specifically, the static electricity removal and detection device 2 includes a touch surface 21, a thin metal sheet sensor at the end 22, a microcontroller 24, an alarm module 23, and a power supply system 25.

[0027] The touch surface 21 is the part that the operator's fingers contact. It is usually made of a material with good conductivity, such as conductive rubber, which not only ensures the smooth conduction of static charge but also provides a comfortable feel. Of course, other materials such as conductive plastic can also be used instead of conductive rubber. The touch surface 21 is generally flat to facilitate operator touch, and its smooth surface reduces friction between the touch surface and the fingers.

[0028] The metal sheet in the end-effector metal sheet sensor 22 is made of a specific alloy material, and its surface is treated with a special coating to reduce charge loss. This specific alloy material can be a copper alloy, etc., which has good conductivity and stability. The special coating can be a silver plating, etc., which can effectively reduce charge loss during conduction. The metal sheet is usually thin and sheet-like to improve sensitivity to electrostatic signals. In addition to copper alloys, other alloy materials such as aluminum alloys can also be used; in addition to silver plating, other plating materials with low charge loss characteristics can also be used. This metal sheet is installed at the end of the sensing module and connected to the touch surface 21 via a wire to conduct the captured electrostatic signal.

[0029] The microcontroller 24 is the control core of the entire device. It typically uses a high-performance, low-power chip, such as the common 51 microcontroller 24 series. The microcontroller 24 has multiple input / output interfaces to receive signals from the electrostatic sensor and output control commands. It is mounted on a circuit board and connected to other components on the board via soldering. Of course, other models of microcontroller 24 can be selected according to actual needs.

[0030] The warning module 23 includes a light unit 231 and a sound unit 232. The light unit 231 includes LEDs housed within the static electricity removal and detection device 2. The sound unit 232 includes a speaker and a buzzer. The LEDs are typically high-brightness light-emitting diodes (LEDs), usually red, for clear warning. The LEDs are installed inside the device near the light-transmitting cover 3 and connected to the circuit board via wires. Besides red LEDs, other colors or combinations of different colors can also be used. The speaker emits an audible warning; it is typically a small, high-quality speaker installed inside the device near the sound-transmitting hole 5 and connected to the circuit board. The buzzer emits a sharp alarm sound and is also connected to the circuit board, installed in a suitable location to ensure effective sound propagation.

[0031] The power system 25 typically uses button batteries to provide power to the device. Button batteries have advantages such as small size, light weight, and stable power supply. They are installed in the battery compartment inside the device and connected to the circuit board via wires to provide power to various components.

[0032] The combined logic of these components is as follows: when an operator's finger touches the touch surface 21, static electricity from the human body is conducted through the touch surface 21 to the end metal sheet sensor 22. The sensor converts the static electricity signal into a voltage analog signal and transmits it to the microcontroller 24. The microcontroller 24 processes and analyzes the signal. When the voltage value exceeds a preset threshold, the alarm module 23 is triggered. The power system 25 supplies power to the alarm module 23, enabling light and sound warnings. This combined effect can promptly detect and warn of static electricity situations because each component has a clear division of labor and works together to form a complete static electricity monitoring and alarm system.

[0033] Specifically, the chair body 1 is equipped with a fixing screw 6, and the static elimination and static detection device 2 has a screw hole in the middle. The fixing screw 6 is threadedly connected to the screw hole for fixation. The fixing screw 6 is generally made of metal, such as stainless steel, which has high strength and corrosion resistance. The inner diameter of the screw hole matches the outer diameter of the fixing screw 6 to ensure a tight threaded connection. In this way, the connection stability between the static elimination and static detection device 2 and the chair body 1 is further enhanced, preventing the device from loosening or falling off.

[0034] In addition, a light-transmitting cover 3 and a yellow light-shielding cover 4 are installed on the outside of the static electricity removal and detection device 2. The light-transmitting cover 3 is made of transparent plastic or other materials, which has good light transmittance and allows the light emitted by the LED beads to pass through smoothly, serving as a warning. The yellow light-shielding cover 4 is made of yellow plastic or other light-shielding materials, which can adjust the brightness and color of the light to make the warning light more conspicuous.

[0035] A sound-permeable hole 5 is provided on one side of the static electricity elimination and detection device 2. The sound-permeable hole 5 is located inside the static electricity elimination and detection device 2, on the side close to the speaker and buzzer. The function of the sound-permeable hole 5 is to allow the sound emitted by the speaker and buzzer to propagate smoothly.

[0036] Both the sound unit 232 and the lighting unit 231 are connected to the circuit board. A component protective cover 7 is provided on the outside of the sound unit 232. The component protective cover 7 is made of plastic or other materials, and its function is to protect the components in the sound unit 232 from external impacts, dust, etc., and extend the service life of the components.

[0037] The implementation principle of this embodiment is as follows: The antistatic chair of this embodiment integrates a static elimination and static detection device 2, realizing real-time monitoring and timely elimination of static electricity, overcoming the shortcomings of existing technologies that cannot monitor static electricity in real time and whose antistatic effect is passive and unstable. The fixing method of double-layer buckles and fixing screws 6 ensures the stability of the device in various environments, while the warning module 23 can effectively remind the operator to pay attention to the static electricity situation. The entire solution improves the antistatic performance and practicality of the chair, expands the applicable scenarios of the chair, and represents a significant improvement compared to existing technologies.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
