Abstract

The invention discloses a breathing machine host, which comprises a shell, a first partition plate, a second partition plate, a fan assembly and a variable flow pipe. The shell is provided with an inner cavity, a first air inlet communicated with the inner cavity and a first air outlet communicated with the inner cavity. The first partition plate is arranged in the inner cavity to divide the inner cavity into an upper cavity and a lower cavity, the first air inlet is communicated with the upper cavity, and the first air outlet is communicated with the lower cavity; the second partition plate is arranged in the upper cavity to divide the upper cavity into a first cavity and a second cavity, and the second partition plate is provided with a first mounting hole communicating the first cavity with the second cavity; the fan assembly is arranged in the inner cavity and comprises a second air inlet communicating with the second cavity and a second air outlet communicating with the lower cavity. The variable flow pipe is arranged in the first mounting hole in a penetrating mode and provided with a third air inlet communicating with the first cavity and a third air outlet communicating with the second cavity. The first cavity, the second cavity and the variable flow pipe form the air inlet flow channel, air can be subjected to variable flow treatment, and air noise is reduced.

Description

technical field [0001] The invention relates to the technical field of ventilator structure, in particular to a ventilator host. Background technique [0002] Ventilator is a device that can replace, control or change people's normal physiological breathing. It is often used to increase the patient's pulmonary ventilation, improve the patient's respiratory function, reduce the consumption of respiratory power, and save the patient's heart reserve capacity. [0003] A ventilator needs an air source to ventilate a patient. The air source is generated by a fan installed inside the ventilator. However, the fan in the existing ventilator will generate a lot of noise during operation, which affects the use of the ventilator. Contents of the invention [0004] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a ventilator main unit, which can effectively reduce the noise generated by the fan in the existing ventilator durin...
