Abstract
The utility model provides an electric brush assembly of an evaporation blower, and the assembly comprises an electric brush support, electric brush boxes, electric brushes and electric brush springs, wherein the electric brush boxes are arranged on the electric brush support, the electric brushes are arranged in the electric brush boxes, and the electric brushes are connected with the electric brush springs; and the assembly is characterized in that a cross section of the electric brush support is in a shape of a cone. The electric brush assembly of the evaporation blower modifies a conventional horizontal electric brush support to the cone-shaped electric brush support, increases a contact area between the electric brushes and a commutator, and increases an effective length of the electric brush in an effective inner space of the blower; the assembly reduces current density of the electric brushes, reduces electromagnetic noises of electric brush commutation, and prolongs service life of the blower.
Description
Technical field
The utility model belongs to the evaporation fan field, is specifically related to a kind of brush assembly of electric of evaporation fan.
Background technology
Existing evaporation motor mainly is to adopt permanent magnet DC motor to drive impeller of blower to come Cooling Air-conditioning System.Permanent magnet DC motor adds that direct voltage just starts working, and whole system is simple in structure, compact, has obtained using widely in air conditioning for automobiles.Permanent magnet DC motor all comprises brush and commutator, but traditional brush carrier is horizontal arrangement, and this structure makes the effective length of brush be subjected to the restriction in motor internal space, and the contact area of brush and commutator is not ideal enough.
The utility model content
The utility model provides a kind of brush assembly of electric that can increase the evaporation fan of brush and commutator contact area at above-mentioned the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of brush assembly of electric of evaporation fan comprises brush carriage, brush box, brush and brush spring, and described brush box is arranged on the brush carriage, and brush is arranged in the brush box, and described brush connects the brush spring; It is characterized in that the cross section of described brush carriage is tapered.
Further, described brush box and brush are two.
The brush assembly of electric of evaporation fan described in the utility model makes the contact area of brush and commutator be increased by traditional horizontal brush carrier is improved to the taper brush carrier, in effective motor internal space, has increased the effective length of brush; Reduce the current density of brush, reduced brush-commutated electromagnetic noise, prolonged the useful life of motor.
Description of drawings
Fig. 1 is the front view of the brush assembly of electric of evaporation fan described in the utility model;
Fig. 2 is the left view of the brush assembly of electric of evaporation fan described in the utility model.
Embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, 2, the utility model provides a kind of brush assembly of electric of evaporation fan, comprises brush carriage 1, brush box 2, brush 3 and brush spring 4, and described brush box 2 is arranged on the brush carriage 1, and brush 3 is arranged in the brush box 2, and described brush 2 connects brush spring 4; The cross section of described brush carriage 1 is tapered.Described brush box 2 and brush 3 are two.The taper brush carrier makes the contact area of brush and commutator be increased, and in effective motor internal space, has increased the effective length of brush; Reduce the current density of brush, reduced brush-commutated electromagnetic noise, prolonged the useful life of motor.
The utility model not only is confined to above-mentioned embodiment; persons skilled in the art are according to the disclosed content of the utility model; can adopt other multiple embodiment to implement the utility model; therefore; every employing project organization of the present utility model and thinking; do some simple designs that change or change, all fall into the scope of the utility model protection.
