Problems solved by technology
However, there has been no further breakthrough in the cooling of the inhalation temperature of the existing positive pressure oxygen respirators on the market. The common cooling device is to assemble water ice or refrigerant materials, but this will make the inhalation temperature high when the rescuer wears it. Breathing is uncomfortable, which further affects the further application and marketing of positive pressure oxygen respirators

The invention discloses a cooling device in a positive pressure type oxygen respirator. The cooling device comprises a ventilation pipeline. A frame is arranged on the upper side of the ventilation pipeline, and heat dissipation fins are installed in the frame in an inserted mode. The two sides of the cooling fins are provided with anti-explosion cooling fans used for cooling the cooling fins. A sealing cavity filled with a refrigerant is formed in the lower side of the ventilation pipeline; the semiconductor chilling plate is used for cooling the ventilation pipeline and the refrigerant at the same time, the temperature in the ventilation pipeline can be reduced, the refrigerant material can be kept in a solidification state, and when gas at about 50 DEG C enters the ventilation pipeline from the gas inlet, through double-effect cooling of refrigerant melting heat absorption and the semiconductor chilling plate, the temperature of the refrigerant material can be reduced; when flowing out of the air outlet, the air can be rapidly cooled to below 30 DEG C and is supplied to a human body for breathing. The positive pressure type oxygen respirator effectively solves the problem that a traditional positive pressure type oxygen respirator is low in cooling efficiency, a respirator wearer can breathe more comfortably, and the application range of the respirator is widened.
Description
technical field [0001] The invention relates to a relatively large range, in particular to a cooling device in a positive pressure oxygen respirator. Background technique [0002] Positive pressure oxygen breathing apparatus is mainly used for respiratory protection of the wearer at the rescue site when an accident occurs, so as to prevent the wearer from inhaling toxic and harmful gases or suffocating in an oxygen-deficient environment. It is suitable for shipping ships, underground railways, and storage of harmful gases In warehouses, entertainment venues, large shopping malls and high-rise residential buildings and other places of rescue accidents. [0003] In order to meet the rescue requirements in special environments, many countries in the world have increased the research on various respirators. Positive pressure oxygen respirators are widely used in the field of fire rescue because of their convenient use and long protection time. However, there has been no further...
