DETAILED DESCRIPTION OF THE INVENTION

[0018] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting. While the invention is susceptible to various modifications and alternative constructions, it should be understood, that there is no intention to limit the invention to the specific form disclosed, but, on the contrary, the invention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention as defined in the claims.

[0019] In any embodiment described herein, the open-ended terms "comprising," "comprises," and the like (which are synonymous with "including," "having" and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0020] As used herein, the singular forms "a," "an," and "the" designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a secured electric shock prevention device for electric appliances that has the ability to avert electric shock from the electric appliances during the usage of the appliance by the user. Additionally, the proposed device is capable of warning the person regarding the usage of appliance with moist hands and accordingly cut off the power supply for deterring the electric shock.

[0022] Referring to Figure 1, an isometric view of a secured electric shock prevention device for electric appliances is illustrated, comprising a body 101 associated with the device and developed to be installed on an electric appliance, plurality of suction cups 102 is integrated on the body 101, an artificial intelligence-based imaging unit 103 installed on the body 101 and a speaker 104 to warn the person to not touch the appliance.

[0023] The device disclosed herein includes a body 101 that is connected with the device in such a manner that the body 101 is configured on an electrical appliance in a proper manner. The body 101 offers a large storage capacity for several mechanical and electrical units to be placed within the body 101. Also, the body 101 is light in weight and is cast with highly durable materials which are easy to be installed as per the requirement of the user. The outer surface of the body 101 is coated with thin paint sheets which shield the body 101 from dust and water buildup, as well as prevent the body 101 from rusting if exposed to the outer atmosphere.

[0024] The body 101 is equipped with multiple (preferably four in number) suction cups 102 in view of affixing the body 101 on the electrical appliances in a secured manner. The suction cup 102 is made of elastic, flexible material and has a curved surface. When the centre of the suction cup 102 is pressed against the surface. The volume of the space between the suction cup 102 and the flat surface is reduced, that creates a negative pressure to adhere the surface crating a partial vacuum inside the cup. The pressure difference between the atmosphere on the outside of the cup and the low-pressure cavity on the inside of the cup keeps the cup adhered to the surface of the electrical appliances. Further, an artificial intelligence-based imaging unit 103 is mounted on the body 101 in view of capturing multiple images in proximity of the body 101 for determining presence of a person in vicinity of the appliance.

[0025] The artificial intelligence (AI)-based imaging unit 103 refers to a camera that incorporates AI protocols to enhance its functionality and capabilities. AI protocols are used to process and analyses the images or videos captured by the camera, enabling it to perform various tasks beyond traditional image capturing. The AI analysis is performed locally on the camera itself and the real-time processing on the camera enables immediate responses and faster decision- making. The camera captures images or records videos by the help of specialized lenses designed to capture high-quality visuals.

[0026] The captured data is pre-processed to enhance its quality and prepare it for AI analysis. This pre-processing involves tasks such as noise reduction, images stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information from the visual data such as identification of the person present in accessibility of the appliance. Also, an inbuilt microcontroller is pre-fed with the instructions required to control the operation of various components associated with the proposed device.

[0027] Based on the detected presence, the microcontroller activates a non-contact moisture sensor embedded on the body 101 in synchronization with the imaging unit 103 for identifying the moisture level of the person's hand. The non-contact moisture sensor employed herein comprises of an infrared emitter and a receiver. Upon actuation the emitter emits infrared light on the person's hand and when the light collides with the hand, a part of beam is refracted due to moisture and rest of beam is reflected back to a receiver in form of electrical signal and based on which the microcontroller measures and processes the absorbance and reflectance of light to determine the moisture levels on the person's hand. The more the light is absorbed/refracted, the higher the moisture content on the person's hand.

[0028] Herein, in case the detected moisture level surpasses a threshold level, the microcontroller directs a speaker 104 mounted on the body 101 to warn the person to not touch the appliance with wet hands for preventing hances of electric shock for the person. The speaker 104 consists of a set of magnets. One of the magnets is permanent magnate and another one is an electromagnet which made of a conducting coil which is fixed with the diaphragm of the speaker 104. Whenever, the electric current is passed across the coil, the electromagnet either attracted towards the permanent magnets or repelled away from the electromagnet. This back-and-forth movement causes the diaphragm to vibrate and that results in generation of the sound wave which is heard by the person for not touching the appliance with wet hands.

[0029] After warning the person, the distance of the person from the body 101 is being evaluated with the help of a proximity sensor installed on the body 101. The proximity sensor comprises of a transducer, wherein the proximity sensor work by sending out a sound wave at a frequency above the range of human hearing. The transducer of the sensor acts both as a sound receiver and a sound emitter to receive and send the ultrasonic sound wave respectively. As the transducer sends the sound wave, the wave hits the person that is in proximity to the body 101 attached to the electrical appliance and reflects back to the transducer. Then the proximity sensor analyses the distance of the person from the body 101 by measuring time lapses between the sending and receiving of the sound wave. As the proximity sensor analyses the distance, it converts the measured distance into an electrical signal and transmits that signal to the microcontroller.

[0030] In case the monitored distance recedes a threshold distance, the microcontroller actuates a circuit breaker configured in the body 101 and attached with circuit of the appliance for breaking the appliance's circuit in order to prevent chances of electric shock for the person due to contact with the appliance. The circuit breaker works by automatically interrupting the flow of electricity when it detects an overload or short circuit in an electrical circuit. When the current exceeds a certain threshold, the trip mechanism trigger which causes the switch to open and break the circuit, thus preventing the chances of electric shocks to the person due to coming in contact with the appliance.

[0031] Synchronously, a sound detection sensor is embedded on the body 101 for monitoring presence of unusual sound from the appliance. The sound detection sensor used herein is preferably an acoustic sensor that by converting sound waves into electrical signals. The acoustic sensor is designed to detect variations in air pressure caused by sound in the surrounding and transform those pressure fluctuations into electrical signals that is further processed, stored, or transmitted to the microcontroller.

[0032] The acoustic sensor typically consists of a diaphragm, a magnet, and a coil. The diaphragm is a thin, flexible membrane that vibrates in response to the changes in air pressure caused by sound waves in the appliance. When the diaphragm vibrates, it moves the coil relative to the magnet, inducing an electric current in the coil due to electromagnetic induction. As the coil moves within the magnetic field of the sensor, it generates a varying electrical voltage proportional to the diaphragm's motion. This voltage represents the electrical analog of the sound waves and is often referred to as the audio signal. The electrical signal generated by the acoustic sensor is amplified and converted into an analog electrical signal which is processed by the microcontroller. After processing, the microcontroller directs actuation of the circuit breaker to cut off the appliances circuit in order to prevent any chances of electric shock for the person.

[0033] Furthermore, a tester is integrated on the body 101 in view of detecting any flow of current on outer portion of the appliance. The tester uses tools such as voltage tester or multimeters. These tools measure the presence of the voltage or current on the outer casing of the appliance that indicate if there is potential safety hazard such as electrical leakage, improper grounding or improper wring that led to current flow in outer portion of the appliance. Herein, in case the presence of current is detected, the microcontroller directs the circuit breaker to cut off power of the appliance to prevent any chances of electric shock.

[0034] The device is associated with a battery integrated with the device for supplying a continuous DC (direct current) voltage to the components such as motors, microcontrollers and various other components that are associated with it. The battery used in the invention is preferably Lithium-ion battery that is rechargeable once again after getting drained out for proper functioning of the components.

[0035] The present invention works best in the following manner, where the body 101 to be affixed with electrical appliance as disclosed in the proposed invention is fabricated with multiple suction cups 102 for adhering the body 101 securely with the appliance. Now, the artificial intelligence-based imaging unit 103 captures multiple images in vicinity of the body 101 for detecting presence of the person in adjacency of the appliances. Then, the non-contact moisture sensor detects level of moisture of the person's hand and accordingly warns the person via speaker 104 to not touch the appliance with wet hands as a precautionary measure to avoid chances of electric shock to the person. Further, the proximity sensor determines the distance of the person from the body 101 and in case the monitored distance recedes a threshold distance, the circuit breaker integrated in the body 101 and connected with circuit of the appliance to break the appliance's circuit in view of preventing chances of electric shock for the person due to contact with the appliance. Also, the sound detection sensor monitors the presence of the unusual sound from the appliance in order to cut off the appliance for preventing chances of electric shock to the person.
