In order to solve the technical problem of above-mentioned existence, this utility model employing following technical proposals:
A kind of anti-reusable aerosol valve, include valve body, valve rod, valve rod back-moving spring, fixing lid, inner washer and outer washer, being provided with check valve in the aerosol passage of described valve body, described check valve can only supply the aerosol flow in aerosol container through the aerosol passage of valve body.
In the improvement project to above-mentioned anti-reusable aerosol valve, described check valve includes the hollow one-way valve seat being contained in valve body aerosol passage, valve ball in the bellmouth that is contained in one-way valve seat.
In the improvement project to above-mentioned anti-reusable aerosol valve, described check valve is the soft plug of Y-shaped.
In the improvement project to above-mentioned anti-reusable aerosol valve, the aerosol passage upper end of described valve body is tapered channel, and described check valve is the ball plug that can be blocked in this tapered channel.
In the improvement project to above-mentioned anti-reusable aerosol valve, described check valve is " convex " the shaped sliding plug being located on the aerosol channel inlet end of valve body, and the stub end of described sliding plug can keep off on this aerosol channel inlet end.
Compared with prior art, the beneficial effects of the utility model are: owing to being provided with check valve in described valve body, and check valve can only be for the aerosol flow in aerosol container through the aerosol passage of valve body, the most once it is finished aerosol, if want that pressing valve body carries out fill filling again, aerosol inversely cannot be filled in aerosol container due to the effect by check valve, the most just cannot reclaim inhalator jar to reuse, thus prevent illegal retailer by inhalator jar reclaim re-use, more reasonable structure the most of the present utility model, really meet aerosol container use requirement.
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings:
[accompanying drawing explanation]
Fig. 1 is the structural representation that this utility model implements；
Fig. 2 is the structural representation that this utility model implements two；
Fig. 3 is the structural representation that this utility model implements three；
Fig. 4 is the structural representation that this utility model implements four.
[detailed description of the invention]
A kind of anti-reusable aerosol valve, as shown in Figures 1 to 4, include valve body 1, valve rod 2, valve rod back-moving spring 3, fixing lid 4, inner washer 5 and outer washer 6, these are consistent with the structure of current aerosol valve, except that: being provided with check valve 7 in the aerosol passage 11 of described valve body 1, described check valve 7 can only supply the aerosol flow in aerosol container through the aerosol passage 11 of valve body 1.
When this utility model is applied in aerosol container want fill aerosol, fill filling is carried out by lid retrofilling mode, next when using aerosol container, gush out just can flow through the aerosol passage 11 of valve body 1 by the aerosol in container after lower valve rod 2 after use, once it is finished aerosol, if want again to carry out fill filling by lower valve rod 2, aerosol inversely cannot be filled in aerosol container due to the effect by check valve 7, the most just cannot reclaim inhalator jar to reuse, thus prevent illegal retailer from being reclaimed by inhalator jar and re-use, more reasonable structure the most of the present utility model, really meet aerosol container and use requirement.
In embodiment one as shown in Figure 1, valve ball 72 in the bellmouth 711 that described check valve 7 includes the hollow one-way valve seat 71 being contained in valve body aerosol passage 11, be contained in one-way valve seat 71, so when spraying aerosol, valve ball 72 is released the bellmouth 711 of one-way valve seat 71 by the pressure in container, so that aerosol enters into the aerosol passage 11 of valve body 1, use of gushing out from valve rod the most again；And when fill aerosol container again, valve ball 72 can be blocked in the bellmouth 711 of one-way valve seat 71, aerosol is made to cannot be introduced in container, the most just cannot reverse filling aerosol.
In embodiment two as shown in Figure 2, described check valve 7 is the soft plug of Y-shaped, and so when spraying aerosol, the bifurcated of soft plug is up postponed and closes up by the pressure in container, so that aerosol enters into the aerosol passage 11 of valve body 1, use of gushing out from valve rod the most again；And when will fill aerosol container again time, the bifurcated of soft plug is strutted by the aerosol come in from valve rod toward aerosol passage 11 inwall direction, thus makes aerosol cannot be introduced in container by clogging for aerosol passage 11, the most just cannot reverse filling aerosol.
