The invention provides a silencing box and a breathing machine, and relates to the field of medical equipment. The problem that the noise of ventilation equipment is too large is solved. The silencing box comprises a shell, a fan and a rib position group, wherein the shell is provided with a first cavity, a second cavity and a channel communicated the first cavity with the second cavity, and the first cavity is provided with an air inlet; the fan is provided with a fan inlet, and the fan is arranged in the second cavity; the rib position group comprises a plurality of first rib plates; and the multiple first rib plates are arranged in the first cavity and located in the flowing wind direction from the air inlet to the channel, and the multiple first rib plates are distributed in a staggered manner. In the operation process of the fan, noise collected by the second cavity flows into the first cavity through the channel and then passes through the rib position group, the longer the sound wave propagation distance is, the more energy attenuation is, the rib position group reflects and interferes sound waves, and the capacity of the sound waves bypassing obstacles is low, so that the noise reduction effect can be achieved.
Description
technical field [0001] The invention relates to the field of medical equipment, in particular to a sound-absorbing box and a ventilator. Background technique [0002] At present, the common positive pressure ventilation equipment on the market is too noisy when used, which seriously affects the sleep quality of patients and their families. Although it can relieve snoring, hypoventilation and other diseases, it greatly reduces the patient's mental outlook and affects the patient's work, study, Quality of Life. In addition, long-term exposure to high-decibel noise can damage the patient's hearing. Contents of the invention [0003] The objects of the present invention include, for example, to provide a sound-absorbing box, which can improve the problem of excessive noise of the ventilation equipment. [0004] The purpose of the present invention is also to provide a ventilator, which can solve the problem of excessive noise of the ventilator. [0005] Embodiments of the p...
