Abstract

The invention provides a respiratory protection device. The device comprises an outer shell part, a sound amplifying element, a filter part, a main body, a base and a mask. A ventilation opening is formed in the end of the main body, the filter part and the outer shell part are arranged on the end of the main body, a preset spacing distance is arranged between the outer shell part and the main body, the filter part is arranged between the outer shell part and the main body, a ventilation gap is spaced between the filter part and the outer shell part, the main body is arranged on one side of the base, a cavity with an air outlet is formed between the main body and the base, the mask is arranged on the other side of the base, and the sound amplifying element is arranged in the respiratory protection device and used for amplifying the received sound. According to the respiratory protection device, the ventilation gap is formed between the outer shell part and the filter part, the filter part can be protected, the air inlet efficiency is improved, the condition of expiratory dyspnea or depressing is avoided to a certain degree, the sound amplifying element can amplify the sound sent out by a user, and the user can communicate with other persons normally when wearing the respiratory protection device.

Description

technical field [0001] The invention relates to the technical field of respiratory protection, in particular to a respiratory protection device. Background technique [0002] A mask generally refers to a device worn on the mouth and nose, which is used to filter the air entering the mouth and nose, so as to block harmful gases, odors, and droplets from entering and exiting the wearer's mouth and nose. Masks have a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, wearing a mask has a very good effect when working in a polluted environment such as dust. [0003] At present, traditional masks are generally made of gauze or paper, and the periphery of the mask is sealed as much as possible to reduce the exchange speed with the outside air, and long-term wearing will cause breathing difficulties. And a mask with better sealing will block the sound from the user and affect the normal communication between the user and oth...
