[specific embodiment]
Embodiment 1
As shown in Figure 1, be the blowning installation decomposition texture schematic diagram of present embodiment.This blowning installation comprises the elastic sphere 100 that has nozzle bore 110 and non-return hole 120 (referring to Fig. 2), the check-valves 300 of being located at the nozzle 200 at nozzle bore 110 places and being located at 120 places, non-return hole, the non-return portion 210 of nozzle 200 enters elastic sphere 100 inside, and combine closely with nozzle bore 110 edges in that nozzle 200 is peripheral, be provided with shutoff in the non-return portion 210 or open the stop assembly 400 of nozzle bore 110.
Nozzle 200 is provided with annular groove 220, and non-return portion 210 enters elastic sphere 100 by nozzle bore 110, and makes annular groove 220 and nozzle bore 110 interference fit, thereby the junction of nozzle 200 and elastic sphere 100 is sealing.Non-return portion 210 inwalls are provided with fin 212, and fin 212 is projecting inward to the cylindrical space that non-return portion 210 surrounds.The quantity of fin 212 is preferably more than three.
Check-valves 300 comprises valve body 310 and non-return sheet 320, valve body 310 peripheries are interference fit with 120 edges, non-return hole so that its junction keeps sealing, establish stop fin 313 in the valve body 310, quantity is preferably more than three, non-return sheet 320 is positioned at stop fin 313, and can move between stop step 311 on the stop fin 313 and following stop step 312 (referring to Fig. 2).
The cylindrical space that sealing gasket 410 and magnetic rings cylindrical component 420 place above-mentioned non-return portion 210 to surround, and be positioned at the middle part of cylindrical space by fin 212.Be provided with the stop step 211 of stop sealing surface 411 on fin 212, when magnetic rings cylindrical component 420 and packing ring 430 adhesives, sealing surface 411 and stop step 211 are at a distance of a segment distance.Packing ring 430 is fixed on the opening part that nozzle 200 is communicated with elastic sphere 100 with non-return portion 210 inwall interference fit.
The working method of the blowning installation of present embodiment below is described:
When being pressed on the elastic sphere 100, because the space is extruded, it is big that the spheroid internal gas pressure becomes as ambient pressure.When spheroid continues to be extruded, pressure is increasing, when the air pressure in the spheroid increases to a certain degree, be applied to the suction-combining force that outside pressure on the sealing surface 411 surpasses magnetic rings cylindrical component 420 and packing ring 430, sealing gasket 410 is washed open together with magnetic rings cylindrical component 420, sealing surface 411 is blocked step 211 and blocks, and air-flow flows out along the space of 212 of fins, and then jetting nozzle 200.When spheroid was extruded, because the air pressure in the spheroid is greater than ambient pressure, the non-return sheet 320 of check-valves 300 was expressed to down stop step 312 by internal gas, and then seals non-return hole 120, and gas can not spilt from non-return hole 120.The blowning installation that uses present embodiment from the air-flow of nozzle 200 ejections comparable common blow up a balloon stronger, thereby reach good cleaning effect.
After the pressing force of outer bound pair elastic sphere 100 discharged, the shell of elastic sphere 100 relied on the elastic recovery original state of self, because the space increases, gas has diluted trend in the spheroid, and air pressure reduces.Extraneous air then can promote sealing gasket 410 respectively and non-return sheet 320 moves in spheroid, by the polarity between magnetic rings cylindrical component 420 and the packing ring 430, sealing gasket 410 can just can be replied the attracting state with packing ring 430 after the spheroid internal gas pressure is reduced to a certain degree, seal nozzle bore 110, and needn't wait outside pressing force to discharge spheroid.Therefore can prevent effectively that air from entering elastic sphere 100 from nozzle 200.
Embodiment 2
In the foregoing description, the form that check-valves 300 takes non-return sheet 310 to separate with valve body 320.As shown in Figure 3, the check-valves 300 of present embodiment comprises integrated valve body 340 and non-return sheet 330.Valve body 340 inside are the passage (referring to Fig. 5) of hollow, and non-return sheet 330 is that an elastomeric material and an end that covers described passage also are connected with valve body 340 elasticity by flexible connecting portion 350.
As shown in Figure 4, be the vertical view of the check-valves 300 of present embodiment.Non-return sheet 330 diameters are bigger slightly than the diameter of the inner passage of valve body 340, can live this passage from valve body 340 1 end caps, and are connected with valve body 340 by flexible connecting portion 350.
As shown in Figure 5, be the A-A profile of the check-valves among Fig. 4 300.Because non-return sheet 330 and connecting portion 350 are elastomeric material, therefore can open neatly or the inner passage of shutoff valve body 340.When elastic sphere 100 was extruded, the spheroid air pressure inside was greater than external pressure, and non-return sheet 330 is because of diameter is bigger, thereby was pushed internally and blocks passage; When elastic sphere 100 restores to the original state, when air pressure inside reduces,, non-return sheet 330 opens passage thereby being pushed from the outside, and air-flow enters from passage.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
