When the rubber seal ring is arranged in place, the rubber seal ring is pressed and deformed to enable the radial pressing portion to be embedded into and pressed at the annular groove, the end face pressing portion is pressed on the end face of the top of the machine seat shell, the bidirectional seal, namely end face seal and shaft seal, between the motor shaft and the motor shaft hole is achieved, the seal effect is good so that the juice or water can not flow into the machine seat shell, parts in the machine seat shell are effectively protected, installation is convenient, and cost is low.
Description
Technical field
The utility model relates to a kind of juice extractor, relates in particular to a kind of motor axis hole hermetically-sealed construction of juice extractor.
Background technology
Juice extractor is a kind ofly fruit, vegetables can be squeezed into fast to the machine of juice, in its support shell, be provided with motor, motor shaft is piercing in support shell through the motor axis hole of support cover top portion, and then works by motor shaft band dynamic spiral propeller, realizes and squeezes out juice; When not carrying out encapsulation process between motor axis hole and motor shaft, the leakage juice occurring in the process of squeezing the juice easily, in motor axis hole flows to support shell, impacts the parts in it, when serious, even also can cause mechanical disorder, cause juice extractor normally to work; In addition, people conventionally can clean or wiping juice extractor after using juice extractor, and in this process, the water of cleaning or wiping is also easily in motor axis hole flows to support shell.In prior art, realize the method that seals between motor axis hole and motor shaft normally between oil sealing is installed, but oil sealing is not only installed trouble, and cost is higher.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of to be convenient to install, cost is low, and the motor axis hole hermetically-sealed construction of good sealing effect.
The utility model solves the technical scheme that its technical problem adopts:
A kind of motor axis hole hermetically-sealed construction of juice extractor, comprise support shell, its top is provided with motor axis hole, in support shell, be provided with motor, motor shaft is piercing in the top of described support shell through described motor axis hole, on described motor shaft, offer annular groove, described annular groove place is set with O-ring seal, O-ring seal comprises cushion rubber main body, the radial compaction portion coordinating with described annular groove and the end face compressed part coordinating with the top of described support shell, when described O-ring seal is in place, O-ring seal compressive deformation, make described radial compaction portion embed and be pressed on described annular groove place, described end face compressed part is pressed on the top end face of described support shell.
Its center of described O-ring seal, along edge towards having a down dip, forms a flowing water inclined-plane.
Described radial compaction portion is the annular wall that described cushion rubber main body extends axially out along annular groove.
The top end face of described support shell is raised with annular rib, and when described O-ring seal is in place, described rib is close to the bottom of described cushion rubber main body.
The beneficial effects of the utility model are: the utility model by said structure, is sleeved on O-ring seal on motor shaft, and crush seal cushion rubber makes, in its radial compaction portion embedded rings connected in star, to complete installation, simple and convenient, have reduced production cost; When O-ring seal is in place; radial compaction portion is pressed on annular groove place; end face compressed part is pressed on the top end face of support shell; and then the two way seal between motor shaft and motor axis hole---end face seal and sealing have been realized; good sealing effect; juice or water cannot be flow in support shell, effectively protected the parts in support shell.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is partial sectional view of the present utility model;
Fig. 2 is the A place enlarged drawing of Fig. 1.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of motor axis hole hermetically-sealed construction of juice extractor, comprise support shell 1, its top is provided with motor axis hole 11, in support shell 1, be provided with motor 2, motor shaft 21 is piercing in the top of described support shell 1 through described motor axis hole 11, on described motor shaft 21, offer annular groove 22, described annular groove 22 places are set with O-ring seal 3, O-ring seal 3 comprises cushion rubber main body 34, the radial compaction portion 31 coordinating with described annular groove 22 and the end face compressed part 32 coordinating with the top of described support shell 1, when described O-ring seal 3 is in place, O-ring seal 3 compressive deformations, make described radial compaction portion 31 embed and be pressed on described annular groove 22 places, described end face compressed part 32 is pressed on the top end face of described support shell 1.
The utility model by said structure, is sleeved on O-ring seal 3 on motor shaft 21, and crush seal cushion rubber 3 makes, in its radial compaction portion 31 embedded rings connected in stars 22, to complete installation, simple and convenient, has reduced production cost; When O-ring seal 3 is in place; O-ring seal 31 is subject to the effect of annular groove 22 and is in all the time the state of compressive deformation; guaranteed that radial compaction portion 32 is pressed on annular groove 22 places all the time; end face compressed part 32 is pressed on the top end face of support shell 1 all the time; and then the two way seal between motor shaft 21 and motor axis hole 11---end face seal and sealing have been realized; good sealing effect, cannot flow in support shell 1 juice or water, has effectively protected the parts in support shell 1.
As preferred embodiment of the present utility model, O-ring seal 3 its centers, along edge towards having a down dip, form a flowing water inclined-plane 33, and juice or water just can not accumulate on O-ring seal 3 along this flowing water inclined-plane 33 toward dirty, guarantee that sealing is reliable, clean hygiene.
In the present embodiment, the annular wall that radial compaction portion 31 extends axially out along annular groove 22 for cushion rubber main body 34, like this, the cushion rubber main body 34 of O-ring seal 3 can be made thinlyyer, makes the easier compressive deformation of O-ring seal 3.
The top end face of support shell 1 is raised with annular rib 12, when O-ring seal 3 is in place, rib 12 is close to the bottom of cushion rubber main body 34, can further prevent that juice or water from flowing in motor axis hole 11 from the top of support shell 1, has increased the reliability of sealing.
The utility model is convenient to install, cost is low, and good sealing effect, can be widely used in various juice extractors.
