Problems solved by technology

This patent can solve the technical problem that the induction coil outputs the induced current signal without being affected by the external magnetic field, thus causing unnecessary malfunction of the fire extinguisher
However, there are still two problems in this patent. 1. It is difficult to achieve shock resistance. The vibration will cause the magnet to fall off and cause false triggering. trigger coil

Embodiment 1

[0014] The upper cover 1 is provided with a coil 2, a channel is provided in the middle of the coil 2, and a magnet 3 is provided above the channel. The top of the magnet 3 is connected to the temperature sensing sheet 5 through a copper shaft 4, and a spring 7 is provided outside the copper shaft 4, and one end of the spring 7 is connected to the magnet. 3. The other section is connected to the top of the upper cover 1. There are several conductive elements 6 inside the upper cover 1. The main body of the conductive elements 6 is attached to the inner cavity of the upper cover 1. The ends of the conductive elements 6 are bent and lean against the magnet 3 to conduct electricity. The bottom of the element 6 is connected to the circuit of the coil 2 , and the upper cover 1 is provided with two conductive elements 6 arranged symmetrically.

Embodiment 2

[0016] The working principle is as follows: when the temperature rises to the critical temperature value of the temperature-sensing sheet 5, the temperature-sensing sheet 5 is triggered, and under the action of the elastic force of the spring 7, the magnet 3 falls along the direction of the spring, and the magnet 3 passes through the coil 2 to cause the coil to generate an induced current. The induced current sends an electric start signal to the outside.

[0017] There are two conductive elements 6 on both sides of the magnet 3. The conductive element 6 can be made of beryllium copper. Since the conductive element gives the magnet a lateral force, it is not easy to fall off after vibration, ensuring that the vibration will not be triggered by mistake. At the same time, the conductive element constitutes a The loop ensures that the coil will not be affected when a lightning strike occurs.

Abstract

The invention relates to the technical field of fire-fighting equipment, specifically a temperature-sensitive magnetic power generation assembly. A coil is provided in the upper cover, a channel is provided in the middle of the coil, and a magnet is provided above the channel. The top of the magnet is connected to the temperature-sensitive sheet through a copper shaft. There is a spring on the outside of the shaft, one end of the spring is connected to the magnet, and the other end is connected to the top of the upper cover. After leaning against the magnet, the bottom of the conductive element is connected to the circuit of the coil. Compared with the prior art, the present invention has the advantage that the conductive element leans against the magnet, gives the magnet a lateral force, and is not easy to fall off after vibration, ensuring Vibration will not cause false triggers.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a temperature-sensing magnetic power generation component. Background technique [0002] Russian Patent No. 2330701 discloses a signal starter used in an automatic fire protection system. The signal starter is provided with an induction coil with an axial passage and an induction coil whose lower end can move up and down in the axial passage in a casing made of insulating material. Connecting rod. The upper end of the connecting rod is fixed on the top of the shell with a positioning pin made of thermal memory material. The lead-out wire of the induction coil is connected with the electrical signal input end of the fire extinguisher through the binding post arranged on the insulating base with wires. The induction coil of the signal starter is easily affected by the external magnetic field to generate an induced current, thereby causing the connected fire exting...
