Summary of the invention

Technical problem to be solved in the utility model is the present situation at prior art, provides a kind of structure simple more hand vacuum safety box, by the visual sealing state that can directly judge crisper.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this hand vacuum crisper, on the face of joint of box body and lid, be provided with seal ring, form inner concave on the lid, the bottom surface of inner concave is provided with exhaust hole, be hinged with on the sidewall of inner concave and renovate, it is characterized in that: an elasticity wheel rim is installed in described renovating, the mesopore of wheel rim is positioned at the top of exhaust hole, and the lower surface of wheel rim fits tightly on the bottom surface of inner concave, forms the blister thin-walled lid of capping wheel rim mesopore on the upper surface of described wheel rim.When needing sealing, push lid with hand, the air in the crisper can be via exhaust hole, is extruded from renovating in the tolerance clearance with concave surface, and be vacuum state in the crisper this moment, under the atmospheric effect in the external world, and the blister thin-walled on the wheel rim top lid indent of sinking.The variation of therefore visual blister thin-walled lid can directly judge whether be vacuum state in the crisper.Hand vacuum crisper parts provided by the utility model are few, simple in structure, easy to operate, push in crisper promptly vacuum generally speaking.

Preferred as such scheme, can described middle part of renovating offer have in the through hole of shoulder, the sidewall of described wheel rim be provided with and described in take on suitable circular groove, thereby described wheel rim is fixed in the described through hole by being embedded of interior shoulder and circular groove.This renovates the forming work that makes things convenient for product component with the fit system of wheel rim, and assembling easily.

Preferably, described interior shoulder is positioned at the middle part of through hole, and described circular groove is positioned at the middle part of wheel rim sidewall.

Compared with prior art, because the utility model has only set firmly an elasticity wheel rim on renovating, parts are few, and are simple in structure, and the variation of the blister thin-walled lid on visual wheel rim top can be judged the vacuum state in the crisper; And wheel rim and renovate between be embedded fixing mode by interior shoulder and circular groove, the shaping of parts processing is convenient, assembling is more prone to.
