Description

The float resetting-mechanism of pressure cooker

Technical field

The utility model relates to a kind of pressure cooker, in particular to the float resetting-mechanism of a kind of pressure cooker.

Background technique

Most products can not reset only rough in appearance aperture for float on the market, further according to artificially pressing float Pressure resets, and the method influences appearance, and outer view hole is easy without dirty entrance.As Chinese patent literature CN202104748U in A kind of electric pressure cooking saucepan with float-controlled valve resetting device, is related to kitchen appliance technical field disclosed on January 11st, 2012, solves Irreducible problem after float-controlled valve is blocked in the prior art.The utility model embodiment has the electricity of float-controlled valve resetting device Pressure cooker, including pot and pot cover, the pot cover are equipped with float-controlled valve；Position corresponding with the float-controlled valve on the shell of the pot cover The release link installed；One end of the release link is opposite with the float-controlled valve, and the other end is exposed on pot cover shell that user can The one side touched, the release link push the float-controlled valve to moving for the float-controlled valve along axial direction；It is arranged in the release link There is spring, the elastic force of the spring drives the release link edge to be facing axially away from the float-controlled valve and moves.

Therefore it is further improved.

Utility model content

It is easy to make the purpose of the utility model is to provide a kind of simple and reasonable, use stable pressure cooker Float resetting-mechanism, to overcome shortcoming in the prior art.

By a kind of float resetting-mechanism of pressure cooker of this purpose design, inner cover and pressure-bearing including cooperating assembly up and down Plate is equipped with valve deck on the bearing plate；It covers to be equipped in described and interlocks guide rail；The bearing plate and valve deck form movable chamber Room；The float moved up and down is equipped in the active chamber；The active chamber bottom is sealing element；The float is supported on close On sealing；It is bearing plate air hole below the sealing element；The gearing guide rail offers through-hole, and float is moved up and is connected in logical In hole；The through hole is equipped with taper baffle, interlocks the mobile taper baffle of guide rail and float tip contact, moves down float multiple Position.

The valve deck, which corresponds to, is equipped with limiting section and movable through-hole above movable chamber；The float top compartment sliding In movable through-hole, and expose to valve deck；When float is raised to certain position, limiting section offsets with the annular convex platform on float Touching；The gearing guide rail is located above valve deck；The through-hole is located at the relative position that float moves up；The taper baffle is located at logical The inner side in hole.

The through-hole length is greater than the diameter of buoy upper；The taper baffle is arranged horizontal by acute angle；It is described Taper baffle, which is fixedly installed on, to be interlocked on guide rail.

The sealing element is equipped with the support platform for supporting float；There is connection air hole below the support platform Gas collection portion, the interconnecting piece that gas collection portion periphery has matter soft；When pot inner pressure is sufficiently large, air pressure is lifted float by gas collection portion, even Socket part deformation；When pot inner pressure is reduced to designated value, float sinks, and interconnecting piece restores to original state.

The interconnecting piece is the ring structure that section is in U-shape, and there is the bound edge for assembling valve deck in interconnecting piece periphery.

The utility model is mainly made of gearing guide rail, float, valve deck, sealing ring, inner cover, bearing plate；There is pressure condition When (culinary art), float limits by interlocking the through-hole of guide rail and interlocks guide rail, make pressure cooker cover can not turn safety guaranteed with this； In passive state, the gearing guide rail that pot cover drives generates displacement, causes taper baffle effect in float, contacts the two, so Float tenesmus is pushed afterwards, it is ensured that float resets completely, to realize very uncapping after culinary art.It is especially long-term in product Reset caused by the components aging such as silica gel after use is insensitive, this structure has durable reliable, easy to use, cost of manufacture The advantages that lower.
