Description

Pressure gauge structure for firefighting

This creation is related to the technical field of fire-fighting equipment, especially a pressure gauge structure for fire-fighting.

A fire extinguisher is one of the best self-extinguishing tools in the initial stage of a fire, and it is also one of the standard safety equipment in public places.

Also because of the importance of fire extinguishers, relevant laws and regulations also clearly stipulate the inspection time and replacement time. There are generally two types of inspection methods at present, one is to recycle and replace the fire extinguishers in the place by the fire equipment company, but the required cost of this method is too high. The other is that the user checks the status of the fire extinguishers one by one and replaces them.

Although self-inspection has the advantage of reducing costs, it is easy to generate the following defects:

1. The configuration of fire extinguishers in the place may be moved due to aesthetics or moving lines, resulting in omissions in the inspection process by users.

2. The user needs to look at the pressure gauges of the fire extinguishers one by one. The workload is heavy and repetitive, and the pressure gauges of the fire extinguishers are not necessarily located in the user's perspective. Some may need to take out the fire extinguisher to check, and the weight of the fire extinguisher It also tests the physical strength of the user.

Furthermore, whether it is self-inspection or entrusted fire equipment company, the mode of inspection is regular, such as six months or one year. In other words, it will take half a year or a year for the faulty fire extinguisher to be discovered, which will form a loophole in the fire safety of the place.

Therefore, how to monitor all the fire extinguishers in the place immediately and quickly is a problem that needs to be faced in the safety management of the place, so it is really necessary to improve the structure of the fire extinguishers.

In view of the problems and deficiencies of the above-mentioned prior art, the main purpose of this creation is to provide a pressure gauge structure for fire protection, which solves the above-mentioned deficiencies of the prior art through innovative design of the structure.

According to the above purpose of this creation, a pressure gauge structure for fire protection is proposed, which includes a watch case, a scale ring, a measuring element, a rotating needle, a magnetic element, a magnetic sensing element, an electric power unit, and a prompting unit , and a control unit. The watch case has a ring shell and is locked to a fire extinguisher. The scale ring piece and the measuring element are assembled in the ring housing. The rotating needle and the magnetic element are assembled at one end of the measuring element. The magnetic sensing element is matched with the magnetic element and arranged on the ring housing and is electrically coupled with the controller unit, and the control unit is further electrically coupled with the power unit, the reminder sheet and the notification unit. With the composition of the above components, when the pressure of the fire extinguisher is insufficient, the measuring element will cause the magnetic element assembled on it to trigger the action of the magnetic sensing element according to the variable, and let the control unit make the prompting unit output a warning sound or light.

The above-mentioned magnetic element 50 is assembled at the preset position of the measuring element 30, and moves with the deformation of the measuring element 30 to provide a preset magnetic force.

The above-mentioned magnetic sensing element 60 is matched with the movement path of the magnetic element 50, and is arranged in the ring housing 11, and is triggered by the magnetic force to selectively output a magnetic sensing signal. In practice, the magnetic sensing element 60 is selected from a Hall element, a reed sensor, and the like.

The power unit 72 is configured to provide power. In practice, the power unit 72 can be a battery or connected to a commercial power supply. Further, the power unit 72 can be optionally disposed inside the ring housing 11 or on the outer peripheral side of the fire extinguisher E.

The prompt unit 74 is configured to output a warning signal according to a prompt signal signal (such as sound or light, etc.). During implementation, the prompt unit 74 is selected from one of a light emitting element, a buzzer or a combination thereof.
