Abstract
The utility model discloses an anti-leakage structure for a juice extractor. The anti-leakage structure comprises a machine base, a juice extraction cup fixed to the machine base and a spiral propeller arranged in the juice extraction cup. A platform is arranged at the bottom of the juice extraction cup. A center shaft hole is formed in the platform. A center shaft of the spiral propeller penetrates through the center shaft hole and penetrates out of the bottom of the juice extraction cup. A sealing rubber ring is arranged between the center shaft and the center shaft hole. An annular groove is formed in the upper surface of the platform. The upper portion of the sealing rubber ring is embedded in the annular groove and tightly attached to the inner wall of the annular groove. The lower portion of the sealing rubber ring is tightly attached to the lower surface of the platform. According to the anti-leakage structure for the juice extractor, the structure of the attaching portion between the upper portion of the sealing rubber ring and the platform is changed so that extruded pomace can not enter the attaching portion between the sealing rubber ring and the platform, the pomace leakage and juice leakage phenomena are effectively avoided, and reliability of the anti-leakage structure is enhanced; the lower portion of the sealing rubber ring is tightly attached to the lower surface of the platform, so that the sealing fixing function of the sealing rubber ring is achieved.
Description
Technical field
The utility model relates to a kind of juice extractor, relates in particular to a kind of leakage-proof structure of juice extractor.
Background technology
With reference to Fig. 1, Fig. 2, at present, juice extractor on market includes support 1 ' and is arranged on the squeezing cup 2 ' on support 1 ', on the platform 21 ' of squeezing cup 2 ' bottom, be provided with central shaft hole 22 ', the central shaft 31 ' of squeezing cup 2 ' inside spin propeller 3 ' is piercing in squeezing cup 2 ' bottom through central shaft hole 22 ', between central shaft 31 ' and central shaft hole 22 ', O-ring seal 4 ' is installed, the upper and lower surface that top 41 ' by O-ring seal 4 ' and bottom 42 ' are close to respectively platform 21 ', realizes the sealing of O-ring seal 4 ' and fixes; But pomace, under the effect of extruding force, easily enters into the joint place of O-ring seal top 41 ' and platform 21 ' upper surface along the upper surface of platform 21 ', thereby cause the Lou phenomenon of slag, leakage juice.
In order to solve the problems of the technologies described above, by platform 21 ' being raised in to squeezing cup 2 ' bottom, correspondingly spiral propeller 3 ' bottom is provided with the depression 32 ' coordinating with platform 21 ', enters into the joint place of O-ring seal top 41 ' and platform 21 ' upper surface to hinder pomace; But above-mentioned structure, in expressing process, particularly squeezing for a long time, always has a certain amount of pomace and 32 ' enters into the joint place of O-ring seal top 41 ' and platform 21 ' upper surface with the cooperation place of platform 21 ' through caving in, the phenomenon of cause easy leakage slag, leaking juice, reliability is poor.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides the leakage-proof structure of the juice extractor that a kind of reliability is strong.
The utility model solves the technical scheme that its technical problem adopts:
A kind of leakage-proof structure of juice extractor, comprise support, be fixed on the squeezing cup on support and be arranged on the spiral propeller in squeezing cup, described squeezing cup bottom is provided with platform, on platform, offer central shaft hole, the central shaft of described spiral propeller is piercing in described squeezing cup bottom through described central shaft hole, between described central shaft and described central shaft hole, be provided with O-ring seal, the upper surface of described platform offers annular groove, the top of described O-ring seal embeds in described annular groove, and be close to the inwall of annular groove, the lower surface of described platform is close in the bottom of described O-ring seal.
Described platform does not protrude from the bottom surface of described squeezing cup; The end face on described O-ring seal top is concordant with the upper surface of described platform.
The beneficial effects of the utility model are: the utility model offers annular groove at the platform of squeezing cup bottom, when O-ring seal is in place, the top of O-ring seal is embedded in annular groove, and be close to the inwall of annular groove, by changing the structure of O-ring seal top and platform joint place, make the pomace being squeezed be difficult to enter in the joint place of O-ring seal and platform, and then effectively avoided the phenomenon of leaking slag, leaking juice, strengthened reliability of the present utility model; And the lower surface of being close to again platform by the bottom of O-ring seal, realizes the sealing of O-ring seal and fixes.

The specific embodiment
With reference to Fig. 3, Fig. 4, Fig. 5, a kind of leakage-proof structure of juice extractor, comprise support 1, be fixed on the squeezing cup 2 on support 1 and be arranged on the spiral propeller 3 in squeezing cup 2, described squeezing cup 2 bottoms are provided with platform 21, on platform 21, offer central shaft hole 22, the central shaft 31 of described spiral propeller 3 is piercing in described squeezing cup 2 bottoms through described central shaft hole 22, between described central shaft 31 and described central shaft hole 22, be provided with O-ring seal 4, the upper surface 23 of described platform 21 offers annular groove 24, the top 41 of described O-ring seal 4 embeds in described annular groove 24, and be close to the inwall of annular groove 24, the lower surface 25 of described platform 21 is close in the bottom 42 of described O-ring seal 4.
As preferred embodiment of the present utility model, described platform 21 does not protrude from the bottom surface 26 of described squeezing cup 2; In assurance, do not leak slag, do not leak under the prerequisite of juice, platform 21 is without the bottom that is raised in squeezing cup 2, and correspondingly the structure of juice extractor, also without being provided with depression, has been simplified in spiral propeller 3 bottoms; Meanwhile, also reduced widely the central shaft 31 of spiral propeller 3 through the length of O-ring seal 4, convenient installation.
In the present embodiment, the end face on described O-ring seal top 41 is concordant with the upper surface 23 of described platform 21, can further prevent that pomace from entering into the joint place of O-ring seal 4 and annular groove 24, strengthens reliability of the present utility model.
The utility model offers annular groove 24 at the platform 21 of squeezing cup 2 bottoms, when O-ring seal 4 is in place, the top 41 of O-ring seal 4 is embedded in annular groove 24, and be close to the inwall of annular groove 24, by changing the structure of O-ring seal top 41 and platform 21 joint places, make the pomace being squeezed be difficult to enter in the joint place of O-ring seal 4 and platform 21, and then effectively avoided the phenomenon of leaking slag, leaking juice, strengthened reliability of the present utility model; And the lower surface 25 of being close to again platform 21 by the bottom 42 of O-ring seal 4, realizes the sealing of O-ring seal 4 and fixes.
