Description
Technical field
The present invention relates to the vacuum food crisper, belong to the plastics daily necessities field.
Background technology
The vacuum food crisper makes air exhaustion by finger by lower casing compression hemisphere.Existing crisper has only a valve, during use on lid, after pressing hemisphere, the air exhaustion in the container, but valve block can not reset, so exhaust is for once, exhaust repeatedly, air-out is limited in the crisper, degree of vacuum is not high, sealing effectiveness is bad thereby fresh keeping time short, because the user will preserve food and frequent the use long period, so the shortcoming that prior art exists has: the one, poor sealing causes gas leakage, the 2nd, degree of vacuum is not high, and the 3rd, fresh-keeping effect is poor.
Summary of the invention
The objective of the invention is provides a kind of blow off valve repeatedly to work in order to overcome the shortcoming of prior art, and exhaust makes the degree of vacuum height in the container repeatedly, and valve block is good with valve base sealing, the vacuum food preserving box that fresh keeping time is grown.
The technical scheme of vacuum food preserving box of the present invention is: a fresh-keeping box body is arranged, connect lid on the box body, between box body and lid, seal ring is installed, vacuum gas discharge valve and aie escape valve are installed in the lid, it is characterized in that described vacuum gas discharge valve has the screw thread valve seat that connects lid, the elasticity hemisphere is installed on the screw thread valve seat, hemispheroidal inwall mounting spring packing ring, the top of elasticity hemisphere and spring washer is shaped on valve opening, last valve block is arranged on the valve opening, the hemispheroidal outer wall of elasticity is installed the valve block fixed cap, be shaped on deflation hole in the valve block fixed cap, the outer lid greatly of installing of valve block fixed cap, the oral area under the big lid is shaped on bulge loop, and the top and lid bayonet socket of bulge loop contacts, mounting spring under spring washer, lower disc fixed cap and lower disc are installed in the screw thread valve seat, and the other end of spring withstands on the lower disc fixed cap, is shaped on pore in the lower disc fixed cap.
Vacuum food preserving box of the present invention, two valve blocks of the upper and lower installation of its elasticity hemisphere, lower disc is closed after pressing big lid, makes valve block fixed cap compression hemisphere, and the air jack-up in the hemisphere is gone up valve block and is made air exhaustion; After unclamping hand, spring resets hemisphere to go up valve block closes sealing, and lower disc is opened simultaneously, and fresh-keeping box body hollow gas discharge section is to hemisphere, the fresh-keeping several times box body hollow pneumatolytic vacuum negative pressure condition of this action that circulates, thus fresh-keeping lid and fresh-keeping box body are sealed.Two valve blocks of the upper and lower installation of hemisphere are worked in coordination good seal performance during work; Since two valve blocks are arranged, but the repeated multiple times operation makes the degree of vacuum height in the box body, good refreshing effect, and fresh keeping time is long.
Vacuum food preserving box of the present invention, its described elasticity hemisphere can be that silica gel material etc. is made, and the soft intensity of silica gel material is good, long service life.Between screw thread valve seat outer wall and lid, supporting cover can be arranged, have supporting cover to improve valve seat intensity, be specially adapted to big box body.It covers the installation tegillum greatly, is shaped on exhausr port in the tegillum, and this is to select another kind of technical scheme for use, and air can be discharged from tegillum.Its described lower disc can be the umbrella shape lower disc, and the structure of umbrella shape lower disc helps work, improves reliability.Its described aie escape valve has the venting bar, and the venting bar is installed in the fixed cover, and the venting bar has the little spring of resetting and mounting ring, and the venting valve sheet is installed on the venting bar, and the venting valve sheet matches with valve body in the lid, and this valve body is to make one with lid.Put into air during its work in box body, vacuum failure can open the lid.
