The specific embodiment
About feature of the present utility model and technology contents, please referring to following about detailed description of the present utility model and accompanying drawing, and accompanying drawing only for reference with the explanation, be not to be used for limiting this utility model.
Fig. 1, Fig. 2 and Fig. 3 are respectively the 3-3 cutaway view of three-dimensional exploded view, combination longitudinal sectional view and Fig. 2 of first embodiment of the present utility model, this utility model provides a kind of exhaust pressure relief device of sphygomanometer, it mainly includes housing 1, movable part 2, magnetic assembly 3 and coil 4, wherein:
Fig. 4 and Fig. 5 are respectively user mode figure of the present utility model () and (two), during use when absence of electric current coil 4, because of the magnetic attraction effect between magnetic assembly 3 and the magnetic 23, move toward magnetic assembly 3 places and make magnetic 23 drive movable part 2, valve member 22 is drawn close to the side away from valve nozzle 14, this valve nozzle 14 can keep unimpeded state with valve member 22, and this helps fluid and drains (as shown in Figure 4) from each air discharge duct 122 of cap 12; Otherwise, after coil 4 is fed electric current, to between coil 4 and magnetic assembly 3, produce mutual magnetic thrust, when this active force is done the time spent greater than the magnetic attraction between fluid input pressure and magnet assembly 3 and the magnetic 23, coil 4 will promote movable part 2 towards a side of magnetic assembly 3 dorsad away from, so that valve member 22 applying valve nozzles 14 and block its valve nozzle 14 are realized the airtight effect (as shown in Figure 5) of involution.
