Abstract
The utility model discloses an improved structure of a carbon brush of a motor used in a household appliance, wherein the carbon brush in a cuboid structure is sleeved in a carbon brush sleeve, grooves are respectively arranged on two symmetrical lateral surfaces of the carbon brush, and an effective ventilation channel is formed by enclosing the grooves of the carbon brush and the inner surface of the carbon brush sleeve. When the motor works, air flow cools the carbon brush through an air duct, thereby reducing the work temperature of the carbon brush, being favorable for keeping the technical performances of the carbon brush, and accordingly prolonging service life of the motor.
Description
Technical field
The utility model relates to a kind of motor that is used for household electrical appliance, relates in particular to a kind of carbon brush that is used for the motor of household electrical appliance.
Background technology
The blower fan drive motors that uses in the household electrical appliance such as current domestic vacuum cleaners all includes the carbon brush that is used to change direct current and alternating current.This carbon brush is generally strip, carbon brush when work one end face connect with the commutator face of high speed rotating, be in the state that slide relative rubs.Because forming the conductor of commutator must annular space arrange, therefore there are the gap in commutator and the contacted outer surface of carbon brush, this gap can cause the vibration of carbon brush when running up, the crisp easy fracture of carbon brush matter, must be provided with the suitable carbon brush cover of carbon brush shape carbon brush is wrapped up, the contacted end of carbon brush and commutator only stays suitably little part to expose to outside carbon brush overlaps.Because the gap between carbon brush and the carbon brush cover must be enough to the circular runout of carbon brush is constrained within the scope of minimum setting, therefore the carbon brush cover has formed influence to the heat radiation of carbon brush, carbon brush with the influence of the high-speed friction of commutator and overcurrent under produce high temperature, under this condition of high temperature, work for a long time, the correlation technique characteristic of carbon brush can descend gradually, as lubrification, to degradation under the density of the inhibition of electric spark, electric current, high temperature also strengthens the damage of engine commutator simultaneously, finally causes motor performance to descend and the working life minimizing.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of carbon brush for electric machine, and the structure of this carbon brush makes carbon brush can keep lower working temperature, thereby improves motor performance and prolong its useful life.
For solving the problems of the technologies described above, carbon brush for electric machine provided by the utility model has following structure:
A kind of carbon brush for electric machine, the motor that is used for household electrical appliance, described carbon brush comprises the carbon brush body that is socketed in the carbon brush cover, this carbon brush body is a strip, an end face of carbon brush body is provided with the conduction copper pigtail that is fastenedly connected with it, another end face is the cambered surface of and butt suitable with the circular surface shape of engine commutator, electric current is delivered to commutator from the conductive copper pigtail through the carbon brush body, the side of described carbon brush body is provided with a plurality of grooves that connects two end faces, and the inner surface of described groove and carbon brush cover is enclosed the carbon brush cooling air channel.
Preferably, described carbon brush body is rectangular shape.
Further, described carbon brush body is provided with two described grooves, and is located in the same way on two relative sides with the long limit of carbon brush body respectively.
The utility model also comprises a kind of motor that is used for household electrical appliance, and this motor has the described carbon brush for electric machine of aforementioned arbitrary claim.
Compared with prior art, the utility model is reduced the working temperature of carbon brush by cooling air channel is set on carbon brush for electric machine, is of value to the technical performance that keeps carbon brush, and prolongs the useful life of motor.
Description of drawings
Fig. 1 is the front view of the carbon brush body of the utility model embodiment carbon brush for electric machine,
Fig. 2 is the vertical view of the described carbon brush body of Fig. 1,
Fig. 3 is pack into a end view behind the carbon brush cover of the described carbon brush body of Fig. 1.
Mark thereon in conjunction with the accompanying drawings:
1-carbon brush body, 2-carbon brush lead-in wire, 3-carbon brush groove, 4-carbon brush cover.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection range of the present utility model is not subjected to the restriction of embodiment.
The key that the utility model technical problem solves is the cooling of carbon brush for electric machine, the way that present embodiment provides is on the carbon brush body of carbon brush for electric machine cooling air channel to be set directly, high temperature on the carbon brush body just can be taken away by the air in the process cooling air channel like this, thereby reduces the carbon brush temperature.
As Figure 1-3, carbon brush for electric machine body 1 of the present utility model is the rectangle entity, carbon brush body 1 is socketed on the shape carbon brush cover 4 suitable with it, carbon brush cover 4 circular runout during with this body running of carbon brush is limited in the set point, an end face of carbon brush body 1 is provided with carbon brush lead-in wire 2, carbon brush lead-in wire 2 is made of the conduction copper pigtail, and electric current is delivered to commutator from the conductive copper pigtail through carbon brush; Respectively be provided with a groove that connects two end faces on two relative sides of described carbon brush body 1 respectively, this groove is identical with the long side direction of carbon brush body, and the inner surface of described groove and carbon brush cover is enclosed the carbon brush cooling air channel.Wind circulation is crossed this cooling air channel and is made the carbon brush cooling during carbon brush work.
The utility model is by being provided with the fluted body structure on carbon brush, temperature reduces when making carbon brush work, and the working stability that is of value to carbon brush is of value to the technical performance of more long-term maintenance carbon brush under better state, prolong the useful life of motor.
More than disclosed only be a specific embodiment of the present utility model, still, the utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection range of the present utility model.
