After adopting the above technical scheme, food processor provided by the utility model has the advantages that

1, food processor provided by the utility model improves the specific structure of existing food processor, Anti-slag cover is set in the mounting base of cup holder side, and anti-slag covers on closes air inlet under natural conditions.In this way, anti-slag cover can crush Knife effectively prevents the intracorporal material of cup or water from entering in suction pipe under the influence of centrifugal force when working, it is ensured that vacuum means Setting is not influenced by material or water, to ensure the vacuumizing function of vacuum evacuation device.When vacuumizing, anti-slag cover opens air inlet Hole does not influence the normal work of vacuum evacuation device.In addition, closing air inlet under natural conditions since anti-slag covers on, moreover it is possible to suitable When the extension dwell time.

2, anti-slag cover is made of connector sleeve and sheets, air inlet be arranged in sheets, on connector sleeve setting for be connected into The specific structure of anti-slag cover is rationally arranged, favorably in the interface channel of stomata and suction pipe under the premise of meeting requirement In the structure of optimization vacuum evacuation device.

3, the thickness of occlusion part is gradually reduced from outer circumferential centre, and air inlet is arranged at the center of occlusion part, Further, occlusion part is in the conical thin-wall shape protruded towards cup lid, so that occlusion part has certain deformability.Air inlet Occlusion part in the raw when aperture very little, be able to achieve the purpose for stopping the intracorporal material of cup or water to enter.Work as air pump When work, occlusion part stress deformation, the aperture increases of air inlet, be conducive to raising vacuum evacuation device vacuumizes efficiency.

The rationally conical centre angle α of setting occlusion part, makes it better meet use under the premise of having deformability It is required that.If α, less than 60 °, deformation of the occlusion part when air pump works is smaller, and the varying aperture of air inlet is little, it is unfavorable for effectively Raising vacuumizes efficiency.If α is greater than 90 °, the deflection after occlusion part stress is excessive, may result in occlusion part and stops in air pump The case where can not restoring to the original state after work.

4, in sheets be arranged around air inlet setting retaining ring, by the retaining ring can further stop the intracorporal material of cup or Water is entered in vacuum evacuation device by air inlet, and the retaining ring will not cover in air inlet when air pump works, to be conducive to Further ensure the vacuumizing function of vacuum evacuation device.The height of retaining ring is rationally arranged in 1mm≤H≤5mm, keeps it preferably full Sufficient requirement.If H is less than 1mm, the height of retaining ring is smaller, unobvious to the barrier effect of material or water.If H is greater than 5mm, gear Circle will not improve the barrier effect of material or water with the increase of height, be unfavorable for controlling production cost.

5, mounting hole is set on cup lid, and connector sleeve is inserted in the mounting hole, and sheets is bonded the inner wall setting of cup lid, limit Convex ribs are bonded the outer wall setting of cup lid.The bidirectionally limited of connector sleeve is realized by the cooperation of sheets and retaining convex rib, to make to prevent The installation site of slag cover keeps stablizing, and better meets requirement.

6, in another structure, air inlet is arranged on cup lid, the outer wall setting of the sheets fitting cup lid of anti-slag cover. Under natural conditions, since sheets is close to the outer wall of cup lid, air inlet is in close state, and is realized and is stopped the intracorporal material of cup or water Into the purpose of vacuum evacuation device, the vacuumizing function of vacuum evacuation device is ensured.Air pump work when, sheets stress deformation open into Stomata, enables vacuum evacuation device smoothly to extract the gas in stirring cup, and realization vacuumizes purpose.

7, the diameter of interface channel is gradually reduced from one end close to cup lid to the other end far from cup lid, i.e. interface channel Be arranged tapered, flowed into interface channel even if thering is material or water to pass through air inlet, it is also difficult to flowed into again from interface channel take out it is true In the suction pipe of empty device, to further ensure the vacuumizing function of vacuum evacuation device.

8, the size of air inlet is rationally arranged in 0.1mm≤D≤2mm, realizes it under the premise of satisfaction vacuumizes requirement The purpose for stopping material or water, better meets requirement.If D is less than 0.1mm, the aperture of air inlet is smaller, though it can be effective Blocking material or water, but be unfavorable for guarantee vacuum evacuation device working efficiency.If D is greater than 2mm, vacuumized though can effectively improve The working efficiency of device, but be unfavorable for that material or water is stopped to enter in vacuum evacuation device.

9, vacuum evacuation device further includes check valve, and the flow direction of gas can be limited by the check valve, makes stirring cup Body can be discharged by check valve under the action of air pump in interior gas, and remains in the pipeline of outside air or vacuum evacuation device Gas can not be flowed in stirring cup by check valve, so can effectively extend the pressure maintaining in stirring cup after the evacuation is completed Time, to be conducive to improve vacuumizing effect.
