A mobile respirator has a respiratory device, a pipe, a breathing component, and a power bank. The pipe has two opposite ends respectively connected to the respiratory device and the breathing component, and the power bank is electrically connected to the respiratory device. A user can place the power bank and the respiratory device inside a backpack, and the pipe can be outstretched from the backpack. Thereby, the user can carry the backpack and wear the breathing component, so the user may breathe with assistance of the mobile respirator. By the power bank supplying electricity for the respiratory device, the mobile respirator is mobile outdoors and solves the trouble of dyspnea while exercising or staying outdoors.

Abrégé

A continuous positive airway pressure device has a shell, a diversion sound-absorbing foam pad, a blower, and a partition. The shell has an inlet and an outlet. The diversion sound-absorbing foam pad is disposed inside the shell and forms an airflow passage extending tortuously inside the shell. The blower is disposed on the diversion sound-absorbing foam pad and fluidly communicates with the airflow passage and the outlet of the shell. The partition covers the blower and the diversion sound-absorbing foam pad and has a leading hole fluidly communicating with the airflow passage and the inlet of the shell. After air flows into an interior space of the shell, the air flows through the airflow passage being tortuous and then flows out from the shell, which lengthens flow path of the air, reduces noises generated during the air flowing, and helps the air to flow more fluently.

A blower includes an upper housing and a lower housing. An air flow space and an air outlet passage are formed inside and communicate with each other. A fan is mounted in the upper housing and the lower housing. A driving shaft of a motor passes through the lower housing and is connected to the fan. The upper housing has a first annular rib with an arc-shaped surface at an edge of the air inlet opening. The upper housing has a second annular rib protruding on an inner bottom surface of the upper housing and adjacent to the air inlet opening. When an external fluid flows in the air inlet opening, the fluid can smoothly pass through the arc-shaped surface of the first annular rib. A part of the fluid is blocked by the second annular rib, and thus forms a vertical downward airflow curtain.

A negative pressure protection system has a cover enclosing an inner space, a ventilation duct fluidly communicating with an air outlet port of the cover, a filter having an inlet end communicating with the ventilation duct, and an air exhausting device connected to an outlet end of the filter. The air exhausting device draws air out from the inner space of the cover via the ventilation duct. The air is filtered and purified by the filter and then is exhausted away by the exhausting device.
