Fire-Resistant Safety Cabinet for Rechargeable Electronic Devices

Abstract

This invention relates to a safety cabinet designed to prevent the risks of overheating, fire, or explosion that may occur during charging or use of electronic devices that use rechargeable batteries (such as robot vacuum cleaners, smartphones, tablets, portable power banks, electric scooter / bicycle batteries, etc.). It features a heat-resistant housing and automatic fire-activated doors.

Description

1 TARIFF FIRE RESISTANT FOR RECHARGEABLE ELECTRONIC DEVICES. SECURITY CABIN Technical Field of the Invention This invention (1) enables electronic devices (robot vacuum cleaners, smartphones, etc.) that use rechargeable batteries. charging or using tablets, portable power banks, electric scooter / bicycle batteries, etc. designed to prevent the risk of overheating, fire or explosion that may occur during operation, Safety system with heat-resistant housing (2) and automatic (4) closing covers (3) in case of fire. It is related to the cabin (1). State of the Art In current lithium-ion and similar battery technologies, overheating and thermal runaway (thermal leakage) are a concern. The risk of runaway fires can occur when devices are charging or used intensively, leading to a fire hazard. Since existing safety enclosures are generally closed in design, devices may overheat during charging. There is no natural air circulation to prevent this. In case of fire, extinguishing is mostly done externally. It depends on the systems. This increases both the cost and the maintenance requirements. Purpose of the Invention The purpose of this invention (1) is to ensure the safe storage and charging of rechargeable electronic devices. This system automatically cuts off oxygen supply in the event of a fire, preventing the fire from spreading to the surrounding area. isolation from spreading (Figure 3), and also keeping the lids open during normal use (Figure 2). Thanks to natural air circulation (Figures 5-6), the heat of the device batteries is reduced. It is to lower it. Innovative Features of the Invention - Heat-resistant housing (1): Made of 1.2 mm DKP sheet metal (2), resistant to high temperature and pressure. Durable construction. - Double cap design: Caps (3) connected to the body (2) with screws and nuts (6) at both ends, It is designed to remain open during normal use (Figure 2). - Heat-triggered (4) automatic closing: Lids (2), heat-sensitive plastic or special cord tensioner (4) It is held in place by this material. In case of fire, this material melts / breaks and the lids (3) close quickly by gravity. 2 - Isolation by oxygen cut-off method (5): When the covers are closed (Figure 3) inside the cabin (1) Oxygen flow stops completely, the fire stays inside the cabin(1) without spreading to the surroundings. - Natural air circulation (Figures 5-6): Passive cooling during charging with the covers open (Figure 2). It is provided. - Versatile use: Can be used with rechargeable devices of various sizes. - Flat entrance floor (Figure 5): Suitable for robot vacuum cleaners to enter and exit on their own, without ramps (7) design. - Explosion pressure resistance: The casing (2) will maintain its integrity in the event of a battery explosion. resistance. Application Method of the Invention The main body of the cabin (1) is made of 1.2 mm DKP sheet metal and is painted or coated to withstand high temperatures. It is protected by. There are covers (3) on both sides of the cabinet. In normal use, these covers (3), It is kept open by tension material (4) (plastic or special rope) whose melting point is at a certain temperature. Since the covers remain open during charging (Figure 2), natural airflow occurs in the interior space, and the battery heat is reduced. It falls. In case of fire, the high temperature emitted from the device melts or breaks the tension material (4); The covers (Figure 3), which are supported by a screw and nut connection (6), close quickly by gravity. This sealing completely prevents oxygen from entering, isolating the fire and preventing it from spreading to the surrounding area. The lids are leakproof (5), so the oxygen level quickly falls below the critical threshold. It descends. At the back of the cabinet, a heat-resistant and flame-retardant material is used to route the device charging cables (Figure 6). There is a leakproof cable entry point (8). The internal volume is designed to withstand the explosion pressure. It has been designed. Advantages • Both fire insulation and passive cooling functions are offered in a single product. • It does not require external fire extinguishing systems. • It offers low-cost and maintenance-free use. • Adaptable to various device sizes. • Provides automatic entry / exit convenience for robot vacuum cleaners.
