Detailed Description

The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

The fire extinguishing ball of the utility model can be made into a ball body as a whole, and can also be in other shapes such as a vase, an animal, an artwork and the like, and the ball body is described below. It can be pre-placed on a simple support, which can be placed on a wall, a table, a counter or other places, and can automatically act to extinguish a fire once contacting a fire source when a fire occurs; or manually thrown to a required place by a user to extinguish a fire when a fire occurs.

As shown in fig. 1, is a front view of the preferred embodiment of the present invention. The utility model discloses a ball of putting out a fire mainly includes: the container comprises a hollow container body 3, a fire extinguishing agent 8 filled in the inner space of the container body 3, and an explosion device 5 arranged inside the container body 3, wherein the explosion device 5 is ignited by a lead end. Wherein,

the hollow container body 3 is a low density, frangible shell, such as a plastic foam, paper or other frangible material, and in the preferred embodiment is spherical, since the sphere has the highest volume to surface area ratio and the most uniform omni-directional distribution when in use. The fire extinguishing agent 8 may be, for example, dry powder abc, or other forms of fire extinguishing agents that may be used to effectively extinguish a fire; the explosive device 5 is a low explosive device that can be detonated by a lead wire, and is not sufficient to generate significant shock to a person relatively close to the device during the explosion, and is safe to use. The hollow container body 3 may be assembled by a plurality of parts (for example, two hemispherical shells are assembled). Half of the edge of each ball can have a tongue-like protrusion feature that mates with the groove 4 of the other half of the edge, or other connection means. A small area of the container body 3 is provided with filling means 9 (including filling holes and filling plugs) for filling the fire extinguishing agent 8.

In addition, the leads are staggered on the surface of the container body 3, and at least one end of the leads is connected with the explosion device 5 through a lead hole 62 on the container body 3. Specifically, the leads include a main lead 60 connected to the explosive device 5 and a plurality of sub-leads 61 arranged on the surface of the container body 3 so as to intersect with the main lead 60. The main lead 60 may be one or more (one is shown in the figure), and is connected to one or both ends (or more than two ends) of the explosive device 5. The main lead 60 and the sub lead 61 are at least partially clamped in a groove (not shown) on the surface of the hollow container body 3. The outer surface of the hollow container body 3 is covered with a layer of packaging film 2 or 7.

The utility model discloses when using, for predetermineeing, or manually throw out to the region of firing, consequently any some lead wire (main lead wire or vice lead wire) is lighted the back, then activates explosive device 5, and the explosive force of explosive device 5 can destroy hollow container body to disperse out fire extinguishing agent 8. The dispersed fire extinguishing agent 8 is used for extinguishing fire.

The assembly process of the present invention is as follows, first one of the main leads 60 of the explosive device 5 is passed through the hole 62 in the container body 3 and the other part is embedded in a groove pre-molded in the surface of the container body 3. The other main lead 60 at the other end of the explosive device 5 is also provided. The two housing halves are pressed together and held together by a "tongue/groove" connection 4 or other connection feature. The secondary leads 61 are then placed in other grooves in the surface of the housing, interleaved with (connected to or in contact with) the primary leads 60. A dry chemical fire suppressant 8 is then poured through the filling hole into the container body 3 until it is tightly filled, and the hole is then closed with a filling plug. A plastic shrink wrap film 2 or 7 of a predetermined size is then secured to the container body 3. In the spherical embodiment, a shrink wrap film 2 is held vertically, with the centerline of the annular shrink band spanning and covering the primary and partial

secondary leads

60, 61 in the cavity of the top and base of the assembly, and spanning the centerline of the filler plug, which in this preferred profile is located in the seam between the hemispheres 10. A single shrink band 2 effectively constrains the entire ball assembly into a sealed unit. This completes the basic assembly of the device. In order to ensure the sealing performance of the ball, in the installation process, a proper amount of adhesive or other sealing substances with adhesive performance are needed to be filled in the seam of the container body, between the filling plug and the hole and in the lead hole, so that the container body, the filling plug and the hole, and between the lead hole and the lead are sealed in an adhesive mode, and the effects of protection and moisture prevention are achieved.

Because the utility model discloses in, main lead wire 60 and vice lead wire 61 are crisscross setting on vessel body 3 surface, can guarantee when arbitrary position of fire extinguishing ball contacts the fire source, all can ignite the lead wire fast to explode device 5. Thereby dispersing the fire extinguishing agent 8 to the predetermined range and achieving the best fire extinguishing effect. If the number of the lead wires on the surface of the container body 3 is too small, there is a possibility that the explosion device 5 is not yet ignited when the container body 3 is burned through by the fire source, and in this case, when the device 5 to be exploded is ignited by the fire source, the explosion effect is not expected at this time, and the dispersion of the fire extinguishing agent 8 is large and may not occur within the expected range, so that the fire extinguishing effect is not optimal.

Because the utility model discloses a small, can very conveniently place in advance in the place of easily firing a fire, like the place or the equipment of easily electric wire fire-out in the mill, motor and boiler or easily fire by chemical, by kitchen stove fire, the gas holder top, everywhere of building (including corridor, toilet), each public business office, restaurant, dining room, filling station, school, office, even in the car in order to provide reliable and present basis on further fire protection. The device is fixedly arranged and placed on a simple bracket, and when a fire disaster occurs, the device can automatically generate a fire extinguishing effect once contacting a fire source. In addition, when explosion happens, the explosion sound can be heard, and the alarm effect of reminding nearby people is achieved. When the fire extinguishing agent is used manually, the fire extinguishing agent is very simple and effective, and only needs to be thrown to a fire scene. In addition, it is portable and can be used to help clear a path for escape from a building engulfed by a fire. The use is more rapid and simple.
