Problems solved by technology

During use, the blockage of the filter element, the stalling of the fan, and the bending of the pipe will increase the resistance of the air flow, reduce the air flow, and make it difficult for the user to breathe a sufficient amount of air, causing the user to breathe in an oxygen-deficient environment. The carbon dioxide content in the product will increase, and the user's breathing will be affected, which is not conducive to the user's health

Abstract

The invention discloses a breath protection device and further discloses a protection wearing system with the breath protection device. The breath protection device comprises a shell, a fan device, acontrol device and an air flow sensor, the shell is provided with a mounting opening used for allowing a filter box to be mounted, the fan device is arranged in the shell, the fan device is provided with an air inlet and an air outlet, the air inlet communicates with the mounting opening, the control device is arranged in the shell, the control device is electrically connected with the fan device,the air flow sensor is arranged at the air inlet or the air outlet so as to detect the air flow, and the air flow sensor is electrically connected with the control device. By arranging the air flow sensor, the actual air flow can be detected, the control device adjusts the rotating speed of the fan device according to the change of the air flow, when the air flow is lower than a set threshold value, the control device can control the fan device to increase the rotating speed, it is guaranteed that enough air can be conveyed to a user, the air flow can be relatively constant, and normal breathof the user can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of respiratory protection equipment, in particular to a respiratory protection device and a protective wearing system. Background technique [0002] In some occasions, such as the air environment with high dust content and medical places, it is necessary to use filters to filter the air to ensure that users can inhale clean air and protect their health. Generally, this type of filter includes a shell and a filter box installed on the shell. The filter box has a built-in filter element, and the air is filtered through the filter element in the filter box. Clothes and other clothing, some filters will also be equipped with fans to deliver air. During use, clogging of the filter element, blocking of the fan, and bending of the pipe will increase the resistance of the air flow, reduce the flow of the air, and make it difficult for the user to breathe a sufficient amount of air, causing the user to breathe in an...
