Abstract
The utility model relates to a kind of outer rotor blower fan water-tight device, and it comprises the rotor with iron core, and end cap; End cap is provided with two annular muscle that coordinate with rotor end ring, extends forward in the annular muscle of inner side, and its end protrudes from the annular muscle end in outside.End cap inner annular muscle lengthens, and the cooperate degree of annular muscle and rotor end ring is strengthened, and makes the two gap smaller, and rainwater is difficult to enter.
Description
Technical field
The utility model relates to a kind of outer rotor blower fan, especially relates to a kind of outer rotor blower fan water-tight device.
Background technology
The new road that era development information-based, technicalization impels the producers of blower fan industry to start constantly to inquire into enterprise development, what this was wherein unanimously subject to enterprises pay attention is exactly the cultivation of core technology during blower fan is produced.Higher level for major technologies and equipment production domesticization is pushed to, produce more most advanced and sophisticated product, secondary development and omnibearing autonomous innovation are the mains goal of attack of numerous blower fan enterprise.Outer rotor blower fan manufacture and design multiple ambits such as relating to aerodynamics, thermodynamics, thermal conduction study, materialogy, mechanical theory.
Along with the continuous variation of outer rotor blower fan environment for use, indoor and the outdoor requirement of versatility with market, indoor often environment for use is good, but when outdoor application, often environment is more rainy, conventional outer rotor blower fan can not adapt to use in this changeable environment, outdoorly tend to make motor internal water inlet when rainy, make its short circuit, the risk that causes motor and integrated equipment thereof to burn.
Summary of the invention
The utility model main purpose is to provide the good outer rotor blower fan water-tight device of a kind of water resistance.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: outer rotor blower fan water-tight device, comprise the rotor with iron core, and end cap; End cap is provided with two annular muscle that coordinate with rotor end ring, it is characterized in that: the annular muscle in inner side extends forward, and its end protrudes from the annular muscle end in outside.End cap inner annular muscle lengthens, and the cooperate degree of annular muscle and rotor end ring is strengthened, and makes the two gap smaller, and rainwater is difficult to enter.
As preferably, described end cap outer setting waterproof protecting cover; Waterproof protecting cover is annular solid, be set on end cap, and envelope hides the joint portion of annular muscle and rotor end ring.The outside waterproof protecting cover that increases of end cap, structurally waterproof protecting cover covers end cap and with the fit clearance of rotor, effectively reduces the possibility that rainwater enters.
As preferably, the main body of iron core is seamless solid.Rotor surface atresia, has broken off the possibility that water enters from rotor core surface.
Therefore, the utlity model has good performance.
Brief description of the drawings
Accompanying drawing 1 is a kind of structural representation of rotor.
Accompanying drawing 2 is a kind of structural representations of end cap.
Accompanying drawing 3 is a kind of structural representations of waterproof protecting cover.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the utility model outer rotor blower fan water-tight device, as shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, it comprises the rotor 1 with iron core 11, and end cap 2; End cap 2 is provided with two annular muscle 21,22 that coordinate with rotor end ring 12, it is characterized in that: the annular muscle 22 in inner side extends forward, and its end protrudes from annular muscle 21 ends in outside.End cap 2 outer setting waterproof protecting covers 3; Waterproof protecting cover 3 is annular solid, is set on end cap 2, and envelope hides the joint portion of annular muscle 21,22 and rotor 1 end ring.The main body of iron core 11 is seamless solid.
Traditional motor be stator outside, rotor produce power.Outer rotor blower fan is structure in contrast, and stator is in the centre of motor, and rotor outside.Outer rotor blower fan is to have adopted outer rotor blower fan directly to drive the advanced configuration of fan blade and rational pneumatic design, and have that efficiency is high, noise is low, the feature such as lightweight, compact conformation, installation and maintenance are convenient.
Under the ordering about of social development in science and technology, the requirement that people use centrifugal fan is also more and more higher, more efficient and adaptability is stronger, the life-span higher outer rotor blower fan demand increasing, the outer rotor blower fan that has waterproof structure can be applied to more bad working environments.
The utility model adopts novel rotor core structure, by the transfer of internal heat dissipating system, makes rotor surface atresia, has broken off the possibility that water enters from rotor core surface.Meanwhile, reduced the processing to louvre, saved electric energy, cost of labor, has improved production efficiency.The aluminium pollution of bits to environment and the injury to operating personnel's health are reduced.
End cap inner annular muscle lengthens, and the cooperate degree of annular muscle and rotor end ring is strengthened, and makes the two gap smaller, and rainwater separates acting in conjunction by its surface tension and rotor dehydration, is difficult to enter.
The outside waterproof protecting cover that increases of end cap, structurally waterproof protecting cover covers end cap and with the fit clearance of rotor, makes waterproof protecting cover, annular muscle, rotor end ring three form W structure, effectively reduces the possibility that rainwater enters.The lengthening of end cap end ring length and the increase of waterproof protecting cover, initiated W type structure, improved motor classification of waterproof.
