Abstract

The invention discloses a portable nose mask. The nose mask comprises a mask casing, a separating plate, a fan and a battery for providing electric energy for the fan; the mask casing adopts the casing structure with an open back end surface; an exhaust channel is formed in the mask casing; the separating plate is arranged in the mask casing and divides space, except the exhaust channel, of the mask casing into a front air inlet cavity and a back air changing cavity in the front-and-back direction; a gap for communicating the front air inlet cavity and the back air changing cavity is formed inthe separating plate; one end of the exhaust channel communicates with the back air changing cavity, and the other end forms an exhaust hole in the mask casing; multiple air inlets communicating withthe front air inlet cavity are formed in the front end surface of the mask casing; the fan and the battery are arranged in the front air inlet cavity; and air is driven by the fan to be sucked into the mask casing along the air inlets and then be exhausted outwards along the exhaust hole. The battery and the fan are directly mounted in the mask casing, and the air is directly sucked into the maskcasing by the aid of the fan, so that the nose mask is simple in structure and is not required to be additionally equipped with a connecting air pipe, the resistance produced by the connecting air pipe is reduced, and the nose mask is convenient to use.

Description

technical field [0001] The invention relates to a portable nasal mask, in particular to a portable continuous positive pressure nasal mask. Background technique [0002] The existing nasal mask structure usually consists of three parts: a compressor, a breathing circuit, and a nasal mask. The breathing circuit is connected to the compressor and the nasal mask. cheek side. Due to the exposure of the breathing tube and the need to wear a compressor, the user's head movement is severely restricted, and the nasal mask often tilts and the breathing tube falls. Therefore, there is the technical defect of inconvenient use in the existing nasal mask structure. Contents of the invention [0003] The invention provides a convenient and portable nasal mask. The technical solution adopted by the present invention to solve its technical problems is: [0004] A portable nasal mask, comprising a mask shell, the mask shell is a shell structure with an open rear end, and also includes ...
