DETAILED DESCRIPTION
[0027] The following is the specific embodiment of the utility model and combining with the drawings, the technical scheme of the utility model is further described, but the utility model is not limited to these embodiments. Example one:
[0028] As Figs. 1-4 shown, an oxygen inhaler testing device, the oxygen inhaler 1 includes low pressure oxygen output port 11, the testing device includes detector 2 and connecting hose 3.
[0029] The detector 2 is provided with oxygen flow detection interface 21, preferably, the detector can adopt handheld oxygen inhaler detector OIT-3 produced by Nanjing Mingrui Detection Technology Co., Ltd.
[0030] One end of the connecting hose 3 is connected to the oxygen flow detection interface 21, preferably, one end of the connecting hose 3 is provided with a clamping nut, the outer side of the oxygen flow detection interface 21 is provided with an external thread, and the clamping nut of the connecting hose 3 is threadedly connected to the oxygen flow detection interface 21, the other end of the connecting hose 3 is provided with a joint body 4.
[0031] The first blind hole 5 is provided with a lower through hole 41 penetrating the joint body 4 at the bottom thereof, and a through hole 42 is provided in the sidewall of the first blind hole 5.
[0032] The first blind hole 5 is provided with a lower through hole 41 penetrating the joint body 4 at the bottom thereof, and a through hole 42 is provided in the sidewall of the first blind hole 5.
[0033] The first blind hole 5 is provided with a lower through hole 41 penetrating the joint body 4 at the bottom thereof, and a through hole 42 is provided in the sidewall of the first blind hole 5.
[0034] Since one end of the connecting hose 3 is always connected with the oxygen flow detection interface 21 of the detector 2, and the other end is detachably connected with the low-pressure oxygen outlet 11 of the oxygen inhaler body 1 through the joint body 4, the oxygen inhaler can be quickly replaced without repeatedly plugging and unplugging the connecting hose 3 by the operator, thereby saving time and effort.
[0035] In the initial state, the connecting hose 3 is not in communication with the lower through hole, and when detection is needed, the low-pressure oxygen outlet 11 is inserted into the lower through hole of the joint body 4, and then the communication hole 75 is brought into communication with the lower through hole 41 through the communication mechanism, at this time, the lower through hole 41 is in communication with the through hole 42, and detection can be carried out, at the same time, the low-pressure oxygen outlet 11 can be fixed in the joint body 4 and cannot move, thereby avoiding the connecting hose 3 from falling off and affecting the detection work.
[0036] In this embodiment, the bottom of the first blind hole 5 is provided with a plurality of guide columns 52, the bottom of the movable block 7 is provided with a plurality of third blind holes 73, the upper end of the guide column 52 is slidingly arranged in the corresponding third blind hole 73, and the third blind hole 73 and the guide column 52 are fixedly connected with a return spring 74.
[0037] Under the action of the return spring 74, the movable block moves away from the bottom of the first blind hole 5, at this time, the communication hole 75 is not in communication with the through hole 42.
[0038] The first blind hole 5 is provided with a lower through hole 41 penetrating the joint body 4 at the bottom thereof, and a through hole 42 is provided in the sidewall of the first blind hole 5.
[0039] In the embodiment, the communication mechanism comprises a second blind hole 71 formed on the lower side of the movable block 7, the communication hole 75 is communicated with the second blind hole 71, and the bottom of the second blind hole 71 is obliquely provided with an elastic rod 72. When the low-pressure oxygen outlet 11 is inserted into the second blind hole 71, the elastic rod 72 can be inserted into the low-pressure oxygen outlet 11.
[0040] When the low-pressure oxygen outlet 11 is inserted into the lower through hole 41 of the joint body 4, then the handle 6 is rotated, the movable block 7 is pushed to move downwards to contact the bottom of the first blind hole 5, and at the same time, the elastic rod 72 in the second blind hole 71 is inserted into the low-pressure oxygen outlet 11. Since the elastic rod 72 is obliquely arranged, the end portion inserted into the low-pressure oxygen outlet 11 plays a clamping role, avoiding the low-pressure oxygen outlet 11 from sliding out and affecting the calibration work. Embodiment two:
[0041] As shown in Figs. Figs. 1-2 The communication mechanism comprises an inclined hole 76 formed on the lower side of the movable block 7, and the communication hole 75 is communicated with the inclined hole 76.
[0042] When the low-pressure oxygen outlet 11 is inserted into the lower through hole 41 of the joint body 4, then the handle 6 is rotated, the movable block 7 is pushed to move downwards to contact the bottom of the first blind hole 5, and at the same time, the end portion of the low-pressure oxygen outlet 11 is pressed into the inclined hole 76. Since the oblique side wall of the inclined hole 76 is pressed with the low-pressure oxygen outlet 11, the low-pressure oxygen outlet 11 is fixed, avoiding the low-pressure oxygen outlet 11 from sliding out and affecting the calibration work.
[0043] In the embodiment, the side wall of the first blind hole 5 is a tapered surface with the upper part being larger and the lower part being smaller, and the movable block 7 is also a circular truncated cone with the upper part being larger and the lower part being smaller.
[0044] In the initial state, the movable block 7 is separated from the first blind hole 5. Since the outer sides of the first blind hole 5 and the movable block 7 are tapered surfaces matched with each other, when the handle 6 is rotated to push the movable block 7 to move downwards, the gap between the side of the movable block 7 and the side wall of the first blind hole 5 becomes smaller and smaller. When the movable block 7 contacts the bottom of the first blind hole 5, the movable block 7 is completely attached to the side wall of the first blind hole 5, so that the gas discharged from the communication hole 75 can completely enter the perforation 42 and then flow into the connecting hose 3, and will not flow out from the gap between the movable block 7 and the first blind hole 5, thereby improving the accuracy of the calibration.
