Abstract

A fire and smoke containment and extinguishing apparatus comprising a fire retardant bag 1, and an automated fire extinguisher 2 and filtration device 4 located inside said bag 1. The fire extinguisher 2 may be suitable for extinguishing electrical fires, and is automatically activated in the event that the contents of the bag 1, such as a battery powered device 8 or charger 7 catch fire or explode, and the filter 4 removes any harmful smoke. The filter 4 may be a charcoal or carbon filter, and may be fitted to the lid of the bag via brackets 3. The lid of the bag may be closed via hook and loop fasteners, a zip or button closure. The bag may have a pocket 6 for holding a charger 7. The bag may have an inlet and outlet to allow air to pass into and out of the bag.

Description

Battery Safety Device

Background o f the Invention:

In the past few years there has been an exponential increase in the use of Lithium batteries (Lithium Polymer or Li-Po and Lithium Ion or Li-Ion), they are advantageous due to their compactness, performance and high energy density. They are used in laptop computers, MP3 players, electronic cigarettes, mobile phones, self balancing scooters, hover-boards, remote control cars, planes, boats, drones and the majority of cordless power tools.

Various systems are available including lithium battery “fire bags”, “Li-Po Safe Bags” and “Li-Po Guard” bags, these have improved and developed over time by using different composites and utilizing different metals within the material to improve resistance to heat, fire and explosions.

There are also various bulky systems which use double metal layers or layers filled with heavy fire-retardant chemicals in a balloon type layer, however, these are very bulky and are only suitable for small batteries, they are not practical for large power tools or hover-boards, they would be the size of a car.

For portability my invention has to be a bag, none of the lithium battery bags solve the problem of toxic smoke, fumes and gasses given off by the explosion and burning of the batteries. They also do not actively extinguish the fire, the bags reduce the chances of the fire spreading by containing the fire and cutting off the air from the battery for the purpose of extinguishing the fire.

Statement o f Invention:

The present invention seeks to provide a solution to the problem(s) by making use of a fire retardant package which comprises of an automatic fire extinguisher, that allows for more effective and reliable extinguishing of an electrical fire in the event of battery, electrical or charging failure. The invention seeks to provide a solution to the problem(s) of smoke, toxic fumes and gasses by using a filter to remove them from the air.

In one preferred embodiment the invention provides a portable fire resistant enclosure comprising of: 1. Bag made from a PVC, cloth and fireproof glass fibre, copper, zinc and silicone layered cloth with edges sealed with adhesive bonding and multi nylon threads woven together. The lid of the bag is fastened with Velcro on all sides of the opening on the bag. 2. An automatic fire extinguisher fastened to the inside of the bag which will assist putting out the fire and 3. An activated charcoal filter at the top of the bag, the filter removes toxic smoke and fumes from the fire.

The use of this invention will offer the advantages of: 1. Better success of extinguishing the fire with the addition of an automatic fire extinguisher 2. Removing dangerous smoke and fumes with the use of a filter 3. Improved safety.

Introduction to Drawinss

The invention is further described with reference to the accompanying drawings in which Figure 1 is a front view, Figure 2 is an end view, Figure 3 is a plan view. Figure 4 is a plan view of the underside of the bag lid and Figure 5 which is not yet included is a three dimensional view.

The numbering of the different elements is consistent throughout the different drawings:

Element 1 - The bag

Element 2 - Automatic fire extinguisher

Element 3 - Brackets for the automatic fire extinguisher

Element 4 - Activated charcoal / carbon filter

Element 5 - Lid flaps with Velcro fastening

Element 6 - Pocket for holding charger

Element 7 - Charger

Element 8 - Battery powered device (in this example a self balancing scooter / hover-board)

Element 9 - Carry straps

In this example the bag is to contain the battery powered device (element 8) and in the bag (element 1) there is an automatic fire extinguisher (elements 2 and 3) which will automatically release the contents if the battery powered device or the charger explode or catch fire, there will in the event of a fire or an explosion be a potentially dangerous level of toxic fumes and smoke, which will be filtered with the use of a carbon or activated charcoal filter (element 4). The strong fastening of the Velcro (element 5) will help contain the smoke.

The charger (element 7) is kept neatly away from the battery device (element 8) and contained within a pocket (element 6) on the inside of the bag (element 1). This means that this invention will prevent a fire from both the battery powered device (element 8) and the charger (element 7) and the use of carry straps (element 9) also means this invention functions as a carry bag.
