AI Technical Summary
The lack of effective failure warning mechanisms for existing filter canisters makes it difficult for wearers to assess their protective performance in a timely manner, posing a safety hazard.
Design a small, lightweight filter canister failure early warning device, including a sensor, a data processing module and an alarm device, to monitor the gas concentration of the filter canister in real time and provide an early warning before failure, reminding the wearer to evacuate or replace the filter canister through a buzzer or indicator light.
It enables timely reminders to wearers to evacuate or replace the filter canister before it fails, ensuring the safety of operators, adapting to various gas detection scenarios, and extending the device's operating time.

Abstract
Claims
1. A canister failure warning device, characterized by, This includes failure warning devices and alarm devices installed inside the filter canister; The failure warning device is placed in the filter canister chamber and includes a sensor and a data processing module. The sensor is integrated with the data processing module through pins. The data processing module includes a main control chip, a Bluetooth module, a temperature detection module, a pressure detection module, and a battery management module. The alarm device includes a buzzer, which is connected to the data processing module via pins; The internal chamber of the filter canister consists of, from top to bottom, a smoke filter layer, a mesh plate, an adsorption layer, a device protective cover, a failure warning device, an adsorption layer, and a lower mesh plate. The failure warning device is isolated from the adsorption material of the surrounding adsorption layer by the device protective cover, and the failure warning device is placed at a height of 2-8 cm from the lower mesh plate. The top of the protective cover is a filter screen plate, which must be able to completely cover the failure warning device; the bottom of the protective cover is a circular perforated plate with small holes evenly distributed, and the diameter of the circular perforated plate is the same as the inner diameter of the filter canister. The failure warning device is fixed to the device protective cover by the installation structure, which isolates the failure warning device from the adsorption material of the adsorption layer.
2. The device according to claim 1, wherein The failure warning device includes several sensors, and the sensors for different gases have different shapes.
3. The device according to claim 1, wherein The data processing module is equipped with a battery and is self-powered.
4. The device according to claim 1, wherein Both the upper and lower mesh plates have filter sheets on their outer sides to prevent activated carbon from entering the chamber.
5. The device according to claim 1, wherein The filter canister is equipped with a switch on its exterior, which is connected to a failure warning device. The switch is positioned at the same height as the failure warning device, and the failure warning device can be activated and deactivated via the switch.
