Accurately-controlled air distribution tank device

Abstract

The invention discloses an accurately-controlled air distribution tank device which comprises an air distribution tank, an air inlet part and an air outlet part. The air inlet part comprises an air inlet motor, an air inlet distribution disk, an air inlet bottom cap and an air inlet tank. The front end of the air distribution tank is positioned inside the air inlet tank. The air inlet bottom cap is fixed at the front end of the air distribution tank and is contacted with the air inlet distribution disk. The air inlet motor is connected with the air inlet distribution disk. The air outlet part comprises an air outlet motor, an air outlet distribution disk and an air outlet bottom cap, wherein the air outlet bottom cap is fixed at the rear end of the air distribution tank and is contacted with the air outlet distribution plate; and the air outlet motor is connected with the air outlet distribution disk. According to the invention, the air inlet motor / the air outlet motor drives the air inlet distribution disk / the air outlet distribution disk to rotate a fixed angle according to the set direction so as to change the relative position of the air inlet distribution disk and the air inlet bottom cap as well as the relative position of the air outlet distribution disk and the air outlet bottom cap. Thus, air inlet and air outlet are accurately controlled.

Description

technical field [0001] The invention relates to a device for controlling air intake and discharge, in particular to a precisely controllable gas distribution tank device, which belongs to the field of medical equipment. Background technique [0002] Traditional physical therapy and rehabilitation equipment (air wave therapy series) mostly use electromagnetic valves to control the inflatable airbags to inflate, expand, squeeze, and deflate in an orderly and rhythmic manner, forming a circulatory pressure on the limbs and tissues, so as to promote the circulation of blood and lymph. flow and improve microcirculation. [0003] The solenoid valve control has the following shortcomings: 1) The adjustment accuracy is limited: the solenoid valve usually only has two states of switch, the valve core can only be in two extreme positions, and cannot be adjusted continuously; 2) The cleanliness of the regulating medium is not up to the standard. When required, there is a risk of corro...

Problems solved by technology

[0003] The solenoid valve control has the following shortcomings: 1) The adjustment accuracy is limited: the solenoid valve usually only has two states of switch, the valve core can only be in two extreme positions, and cannot be adjusted continuously; 2) The cleanliness of the regulating medium is not up to the standard. When required, there is a risk of corroding the solenoid valve, thereby reducing the stability of product performance and shortening its service life; 3) When multiple solenoid valves are used at the same time, the volume is large, which affects the external structure of the product; at the same time, the cost of the product is increased
