Abstract
The utility model provides a high-pressure oxygen flow adjusting device for a respirator. The high-pressure oxygen flow adjusting device has the advantages of electricity and gas integration, smaller size and high safety and reliability in use. The whole device comprises a control panel, a micro direct current motor, a screw, a conical head, a pressure spring, a position detector, a pipeline system and the like. The work principle of the device is seen in appended drawings of an abstract; the position sensor is used for converting a position signal of the screw into an electrical signal and transmitting the electrical signal to the control panel; the control panel is used for controlling the micro direct current motor to rotate in forward and reverse directions and drives the screw to vertically move; a conical tip of the conical head is vertically arranged above a mouth of a high-pressure oxygen delivery pipeline in a flow adjusting area; when the motor drives the screw to move downwards, the screw pushes the conical head and the conical head presses a pressure spring to move downwards; the conical tip of the conical head enters the high-pressure oxygen delivery pipeline; the section area of the pipeline mouth is reduced due to the entrance of the conical tip and the high-pressure oxygen flow flowing into the pipeline is correspondingly reduced until the high-pressure oxygen delivery pipeline is completely blocked by the conical head; at the same time, no high-pressure oxygen is outputted, i.e., the output amount is zero; when the motor drives the screw to move upwards, the pressure spring pushes the conical head to a balance position due to the rebound effect, the section area of the pipeline mouth is increased due to the leaving of the conical tip and the high-pressure oxygen flow flowing into the pipeline is correspondingly increased until the conical head returns to the balance position and the conical tip completely leaves from the pipeline mouth; and at the same time, the high-pressure oxygen output amount is 100 percent and the section areas of the high-pressure delivery pipeline blocked by the conical head are different, so that the oxygen amounts of high-pressure oxygen flowing through the pipeline are different and the adjustment of the oxygen flow is realized.
