Stovetop fire suppressor initiator device and method
View Patent ↗An initiator with fuse device for an automatic self-contained fire suppressor and method are provided herein. Stovetop fires are a well-known residential and commercial hazard. An initiator with fuse device provides a reliable activation of an automatic stovetop fire suppressor. A device and method which provides a secure and robust attachment of an initiator to a fire suppressor, while reducing required component parts, manufacturing time, and labor, is provided herein. An initiator cup with integral cylindrical extension affords a thermoform attachment of the cup to the fire suppressor container while providing a secure mechanical attachment of the fuse to the initiator cup.
1. An initiator device for a stovetop fire suppressor, the device comprising:
a cup, the cup comprising: a side wall; and
a base wall, wherein the side wall is integral to the base wall; and a cylindrical extension integrated with the base wall and centered in the base wall, wherein, the side wall, the base wall and the cylindrical extension are a single unitary piece:
the cylindrical extension comprising: a center opening;
an outwardly directed extension; and a fuse extending from an outside of the cylindrical extension into the cup, wherein the cylindrical extension is configured to matingly fit in a hole of a fire suppression container lid.
2. The device according to claim 1 , wherein:
the outwardly directed extension has a length between 0.1 and 0.2 inches when extended.
3. The device according to claim 1 , further comprising:
right angles joining the cylindrical extension to the base wall.
4. The device according to claim 1 , further comprising:
an inner diameter of the cylindrical extension of between 0.10 and 0.12 inches.
5. The device according to claim 1 , further comprising:
an outer diameter of the cylindrical extension of between 0.16 and 0.24 inches.
6. The device according to claim 1 , further comprising:
a wall thickness of the cylindrical extension of between 0.03 and 0.06 inches.
7. The device according to claim 1 , further comprising:
a wall length of the cylindrical extension of between 0.1 and 0.2 inches.
8. An initiator device for a stovetop fire suppressor, the device comprising:
a cup, the cup comprising:
a side wall; and
a base wall; and
a cylindrical extension centered in the base wall, wherein, the side wall, the base wall and the cylindrical extension are a single unitary piece;
the cylinder extension comprising:
a center opening;
an outwardly directed extension;
a wall thickness of the cylindrical extension of between 0.03 and 0.06 inches;
a wall length of the cylindrical extension of between 0.1 and 0.2 inches;
an inner diameter of the cylindrical extension of between 0.10 and 0.12 inches;
an outer diameter of the cylindrical extension of between 0.16 and 0.24 inches; and
right angles joining the cylindrical extension to the base wall; and
a fuse extending from an outside of the cylindrical extension into the cup.
9. The device according to claim 8 , wherein:
the cup is an injection molded plastic cup.
10. The device according to claim 9 , further comprising:
an ultra sonic weld joint at an interface of the cup and a fire suppressor container lid.
11. The device according to claim 10 , further comprising:
a fuse extending from within the cup through the cylindrical extension to an outside of the fire suppressor container lid.
12. The device according to claim 11 , further comprising:
a fuse outer diameter of 0.12 inches.
13. The device according to claim 11 , further comprising:
a fuse without a metallic member.
