The specific embodiment
Need to prove that under the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe the present invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
The present invention is directed to the not high problem of respirator ubiquity flow velocity detection trigger sensitivity in the prior art, propose method and device that a kind of respirator flow velocity triggers self check, below is specifically to introduce the embodiment that a kind of respirator flow velocity triggers self checking method and device:
Fig. 1 is the main flow chart that the described a kind of respirator flow velocity of the embodiment of the invention triggers self checking method, referring to shown in Figure 1, a kind of respirator flow velocity triggers self checking method, comprising: a: select a plurality of flow velocitys as test point according to the flow velocity trigger range of described respirator; B: control to each described test point, detects described test point to the gas flow rate of described respirator output successively; C: the flow velocity of each described test point that detection is obtained and the contrast of the detection index of corresponding preset obtain the result that described respirator flow velocity triggers self check.
Concrete, in the built-in flow velocity detection trigger of respirator module, whole module mainly is made up of flow speed controller and flow rate detection device, wherein flow speed controller is the flow velocity that is used for controlling output gas, require the flow speed controller output area greater than the flow velocity trigger range, and the flow velocity of output is continuously adjustable, and the flow rate detection device is used for detecting the flow velocity of output gas.
