Abstract

The utility model relates to a motor which comprises a rotor shaft, a motor body and a front end cap. A top sealing ring and a bottom sealing ring are sleeved on the rotor shaft, wherein the top sealing ring is in rotary joint with the top of the rotor shaft, and the bottom sealing ring is in rotary joint with the middle portion of the rotor shaft and abuts against the front end cap; and the part of the bottom sealing ring close to the rotor shaft includes an inner ring, an outer ring is in the periphery of the inner ring, the height of the inner ring is lower than that of the outer ring, and an inverted slop is formed between the inner ring and the outer ring. The two sealing rings of the motor can effectively prevent water from penetrating into the motor; when the top sealing ring is damaged, water flows downwardly to the bottom sealing ring, the sealing rings rotate at a high speed with the rotor shaft, and the water is thrown out along the inverted slop of the bottom sealing ring and flows out of the motor from the lateral side of the motor body; and thus, water leakage of the motor can be timely discovered, and maintenance and replacement can be carried out in real time.

Description

A kind of motor

technical field:

The utility model relates to machine field, relates in particular to a kind of motor that can effectively anti-sealing penetrates into motor.

background technology:

Garbage disposer is a kind of modern novel environment friendly kitchen appliance, it provides a kind of brand-new method to process food waste, be mainly used in the pulverization process of food refuse, machine is installed under kitchen basin, and be connected with drainage pipe, its critical piece is for grinding storehouse and motor, motor shaft on motor drives the cutterhead grinding in storehouse to smash food, the water inlet that need to continue when work, motor shaft with grind storehouse due to installation relation may be in decentraction position, in rotation process at a high speed, because producing gap, vibrations leak, water penetrates in motor again whole equipment is caused to damage.

summary of the invention:

The technical problem that the utility model solves is to provide a kind of motor that can anti-sealing infiltration.

The technical scheme in the invention for solving the technical problem is: a kind of motor, comprise armature spindle, body, front end housing, on described armature spindle, be socketed with two sealing rings, described sealing ring is respectively top sealing ring and end sealing ring, described top sealing ring is screwed in the top of armature spindle, sealing ring of the described end is screwed in the middle part of armature spindle and offsets with front end housing, sealing ring of the described end is interior ring near the part of armature spindle, interior ring periphery is outer shroud, the aspect ratio outer shroud of described interior ring is low, between interior ring and outer shroud, has down slope.

Further, the described level angle on slope is 30 °.

The beneficial effects of the utility model: this motor has two sealing rings, can be effectively anti-sealing penetrates into motor, when top sealing ring damages, water down flows to end sealing ring, sealing ring is along with armature spindle High Rotation Speed, water can be thrown out along the slope of falling of end sealing ring, from the body side of motor, flows out, and people can find in time that the situation of leaking of motor is also timely and must overhaul, change like this.

accompanying drawing explanation:

Below in conjunction with accompanying drawing, the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of sealing ring at the bottom of the utility model.

In figure: 1, armature spindle 2, body 3, front end housing 4, sealing ring 41, top sealing ring 42, end sealing ring 421, interior ring 422, outer shroud 423,Dao slope.

embodiment:

A kind of motor as shown in Figure 1, comprise armature spindle 1, body 2, front end housing 3, on described armature spindle 1, be socketed with two sealing rings 4, described sealing ring 4 is respectively top sealing ring 41 and end sealing ring 42, described top sealing ring 41 is screwed in the top of armature spindle 1, sealing ring of the described end 42 is screwed in the middle part of armature spindle 1 and offsets with front end housing 3, as shown in Figure 2, sealing ring 42 of the described end is interior ring 421 near the part of armature spindle 1, interior ring 421 peripheries are outer shroud 422, the aspect ratio outer shroud 422 of described interior ring 421 is low, between interior ring 421 and outer shroud 422, has down slope 423.

Further, the described level angle on slope 423 is 30 °.

This motor has two sealing rings 4, can be effectively anti-sealing penetrates into motor, when top sealing ring 41 damages, water down flows to end sealing ring 42, sealing ring 4 is along with armature spindle High Rotation Speed, water can get rid of 423 along sealing ring 42Dao slope, the end and go out, and from body 2 sides of motor, flows out, and people can find in time the situation of leaking of motor and must overhaul, change in time like this.

It is emphasized that, it is more than preferred embodiment of the present utility model, not the utility model is done to any type of restriction in appearance, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.

Claims (2)

1. a motor, comprise armature spindle (1), body (2), front end housing (3), it is characterized in that: on described armature spindle (1), be socketed with two sealing rings (4), described sealing ring (4) is respectively top sealing ring (41) and end sealing ring (42), described top sealing ring (41) is screwed in the top of armature spindle (1), sealing ring of the described end (42) is screwed in the middle part of armature spindle (1) and offsets with front end housing (3), sealing ring of the described end (42) is interior ring (421) near the part of armature spindle (1), interior ring (421) periphery is outer shroud (422), the aspect ratio outer shroud (422) of described interior ring (421) is low, between interior ring (421) and outer shroud (422), there is down slope (423).

2. a kind of motor according to claim 1, is characterized in that: the described level angle on slope (423) is 30 °.
