Embodiment 1

[0044] A breathing mask for plateau and emergency rescue, such as figure 1 and figure 2 As shown, it includes a body 1, an air exhalation assembly 2, a control unit, a power supply unit, a switch unit and a headband 6;

[0045] In this embodiment, the main body 1 is used to be in contact with the face and can be worn on the user's face; the main body 1 is mainly formed of arc-shaped synthetic resin, and is designed to fit ergonomically with the face, and the airtightness between the face and the face Well, the middle of the mask is raised and forms a breathing cavity for gas to stay between the mouth and nose.

[0046] In this embodiment, there is only one air exhalation component 2 installed on the main body 1, and the position of the air exhalation component 2 is opposite to the mouth and nose, so as to facilitate rapid exhalation of gas. The air exhalation assembly 2 includes an air outlet 201 and an air outlet valve 202 installed on the air outlet 201 , the air outlet v...

Abstract

The invention discloses a breathing mask for plateau and emergency rescue, and belongs to the field of masks. The breathing mask comprises a body, an air exhalation assembly, an air inhalation assembly and a control unit. The air exhalation assembly comprises an air outlet and an air outlet valve; the air inhalation assembly comprises an inhalation valve, an air inlet, a fan and a filter; the filter, the fan and the inhalation valve are sequentially installed at the air inlet according to the air direction; and an expansion connector connected with the filter and / or externally connected with oxygen is arranged on a shell of the fan. According to the mask, through arrangement of a micro-controller and a sensor, the pressure in the mask can be sensed in real time, and the rotating speed of the fan can be automatically adjusted, so that the mask is more suitable for breathing of the human body, especially for meeting the large demand for air in the plateau environment. The expansion connector is additionally arranged on the fan shell, can be externally connected with the filter or an oxygen connector, can filter the air and convey the oxygen at the same time, can enable the mouth andthe nose to breathe, and is applicable to the plateau dilute oxygen environment and the emergency rescue situations.

Description

technical field [0001] The invention relates to a mask, in particular to a breathing mask for plateau and emergency rescue. Background technique [0002] Wear a face mask to protect the respiratory organs or bronchi from toxic substances in the atmosphere. In special cases, such as plateau or fire and other emergency rescue situations, especially when the patient cannot breathe spontaneously, the mask needs to provide oxygen for the patient in addition to preventing harmful substances in the air from entering the respiratory tract from the mouth and nasal cavity. or fresh air to provide normal breathing. [0003] Publication No. CN106102839A discloses a mask, which mainly includes a body, an air purifier and a control unit. Wherein the air purifier includes a filter unit, an air inlet, an air outlet, a blower fan and an adjustment unit for adjusting the rotation speed of the blower fan, and the blower fan mainly regulates the air flow. Wherein the control unit mainly incl...
