Abstract
The utility model relates to a waterproof structure for a motor with an outer rotor, which is capable of not only effectively preventing water from entering the motor with an outer rotor, but also realizing dustproof effect. The waterproof structure comprises the motor with an outer rotor, the height of an annular outer groove wall of an annular groove at the end of the outer rotor in the motor with an outer rotor is larger than that of an annular inner groove wall of the annular groove, the height of an annular outer groove wall of an annular groove at the end of a middle cover of the motor with an outer rotor is smaller than that of an annular inner groove wall of the annular groove, and the annular groove at the end of the middle cover matches with the annular groove at the end of the outer rotor in a convex-concave splicing manner. The waterproof structure has the advantages that 1, the waterproof structure is fine in waterproof performance and can effectively prevent the water from entering the motor, and 2, the waterproof structure is fine in dustproof effect and realizes the purpose of zero dust entering the motor from a wire outlet hole of the motor.
Description
Technical field
The utility model relates to a kind of water that can either stop effectively and enters in the external rotor electric machine, and a kind of external rotor electric machine waterproof construction of dustproof effect can be arranged again, belongs to the required parts of outer rotor waterproof motor and makes the field.
Background technology
All patent applications formerly of the applicant, CN201215105Y, title " dynamic seal water proof outer rotor blower fan ", it comprises outer rotor blower fan, and the external rotor end in the described outer rotor blower fan is boss and is convex-concave grafting movable sealing with the groove of middle cover end and cooperates.
The utility model content
Purpose of design: design a kind of water that can either stop effectively and enter in the motor, again dustproof external rotor electric machine waterproof construction effectively.
Design: the utility model be the applicant all formerly on the basis of patent, realize by further improvement concavo-convex hermetically-sealed construction.The purpose of doing like this is: because the height of the annular external groove sidevall of the cannelure of this external rotor end is greater than the height of the annular internal groove side wall of annular groove, the height of the annular external groove sidevall of external rotor electric machine middle cover end loops connected in star is lower than the height of the annular internal groove side wall of cannelure, air in the gap between the concavo-convex wall in its concaveconvex structure is under the rotation of external rotor, air in the gap forms the malleation air-flow, this malleation air-flow can stop entering of water effectively, thereby reaches the purpose of waterproof and dustproof.
Technical scheme: a kind of external rotor electric machine waterproof construction, it comprises external rotor electric machine, the height of the annular external groove sidevall of the cannelure of described external rotor electric machine China and foreign countries rotor tip is greater than the height of the annular internal groove side wall of annular groove, the height of the annular external groove sidevall of external rotor electric machine middle cover end loops connected in star is lower than the height of the annular internal groove side wall of cannelure, and the annular groove of middle cover end cooperates with the annular groove formation convex-concave grafting of external rotor end.
The utility model is compared with background technology, and the one, water resistance is good, can stop water to enter in the motor effectively; The 2nd, good dustproof effect has realized the dustless purpose that enters motor from the motor wire hole.
Description of drawings
Fig. 1 is the schematic diagram of external rotor electric machine waterproof construction.
Embodiment
Embodiment 1: with reference to accompanying drawing 1.A kind of external rotor electric machine waterproof construction, it comprises external rotor electric machine 1, the height of the annular external groove sidevall 2 of the cannelure of described external rotor electric machine 1 China and foreign countries' rotor tip is greater than the height of the annular internal groove side wall 4 of annular groove, the height of the annular external groove sidevall 3 of external rotor electric machine middle cover end loops connected in star is lower than the height of the annular internal groove side wall 5 of cannelure, and the annular groove of middle cover end cooperates with the annular groove formation convex-concave grafting of external rotor end.
The annular groove of described middle cover end and the annular groove of external rotor end form convex-concave grafting matched in clearance.
What need understand is: though the foregoing description is to the mentality of designing of the present utility model detailed text description of contrasting; but these text descriptions; just the simple text of the utility model mentality of designing is described; rather than to the restriction of the utility model mentality of designing; any combination, increase or modification that does not exceed the utility model mentality of designing all falls in the protection range of the present utility model.
