Abstract
Provided is an integrated rear motor cover structure of a membrane booster pump for a water purifier. The integrated rear motor cover structure comprises a rear motor cover, carbon brush fixing frames and a wire sealing plug are integrated with the rear motor cover, and the carbon brush fixing frames are circumferentially and uniformly distributed on the rear motor cover with a shaft hole of the rear motor cover as the center. The outer side of each carbon brush fixing frame is provided with a carbon brush fixing plate limiting groove correspondingly formed by L-shaped bosses. The carbon brush fixing frames are of a cuboid cavity structure of which the two sides are communicated, and the upper end face of each carbon brush fixing frame is provided with a rectangular hole. Through integration of the rear motor cover, the carbon brush fixing frames and the wire sealing plug, the three components become one component. The assembly structure is optimized, connection components are simplified, the assembly efficiency is improved, the product cost is reduced, the consistency of assembly is ensured, and broad market requirements can be satisfied.
Description
Technical field
The utility model relates to a kind of motor rear cover, the motor rear cover integral structure of diaphragm booster pump for especially a kind of water purifier.
Background technology
Diaphragm booster pump is owing to having good boost performance and lower power consumption, therefore adopting Reverse Osmosis Technology to carry out being widely used diaphragm booster pump as pressurized source in the appliance water product of purification of water quality.
Thereby diaphragm booster pump mainly by direct current permanent magnet motor drive the rotation water is carried out to the supercharging eliminating.Therefore the performance of motor has determined the quality of booster pump.
The running gear of whole motor, the namely rotor of motor.Two of rotor is separately fixed in the bearing on pump housing cage and bonnet.Rotor in pump housing cage one side is drive end, drives the capacity eccentric bearing action of pump head.Rotor afterbody in bonnet one side is equipped with commutator, and commutator is pushed down by two carbon brush, thereby makes electric current flow to enamelled wire by commutator, then, under the interaction in magnetic field, makes rotor produce the power of rotation.Carbon brush is arranged on carbon brush fixing frame, and carbon brush fixing frame by screw fastening on bonnet.Because being artificial adopts four screws that carbon brush fixing frame is fixed on bonnet, exist locking torsion uneven and turn the situation of joining skew, finally cause two carbon brush not full symmetric be fitted in commutator face.Can make thus two carbon brush break-ins inhomogeneous, gently motor produces abnormal sound, heavy can affect life-span of motor.Owing to being the manual assembly screw, so efficiency of assembling is also lower.
Be equipped with the wire seal plug of a quality of rubber materials on motor rear cover, electric wire passes from the hole in the middle of sealing plug.Due to rubber be have necessarily flexible, so the electric wire passed is had to certain extruding fixation, but but increased the operation of parts and assembling rubber seal plug, thereby increased certain cost.
Summary of the invention
The utility model provides the motor rear cover integral structure of a kind of water purifier with diaphragm booster pump, does not need carbon brush fixing frame is carried out to screw fastening, does not also need that wire seal is filled in to luggage and joins; Owing to being one-time formed, so the size of each carbon brush fixing frame is almost completely consistent, thereby improved the assembling consistency of carbon brush.Also improved efficiency of assembling and reduced cost.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the motor rear cover integral structure of diaphragm booster pump for a kind of water purifier, comprise motor rear cover, it is characterized in that: carbon brush fixing frame and wire seal plug and motor rear cover are integrated as a whole, wherein carbon brush fixing frame centered by the axis hole of motor rear cover circumference uniform distribution on motor rear cover; The outside of described carbon brush fixing frame is provided with the carbon brush fixed head stopper slot consisted of L shaped boss correspondence; Described carbon brush fixing frame is the cuboid cavity structure that both sides connect, and the upper surface of carbon brush fixing frame is provided with a slot.
To the further improvement of technique scheme, be provided with a pair of axial semicircle orifice in described wire seal plug, in axial direction successively decrease in the aperture of each semicircle orifice.
Beneficial effect: the utility model improves by the integral structure of motor rear cover, carbon brush fixing frame, wire seal plug, makes three parts become parts.Optimize assembly structure, simplified link, improved efficiency of assembling, reduced product cost, guaranteed the consistency of assembling, can meet wide market demands.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1 is motor rear cover, the 2nd, and carbon brush fixing frame, the 3rd, wire seal plug, the 4th, L shaped boss.
Embodiment
As shown in Figure 1, the motor rear cover integral structure of diaphragm booster pump for a kind of water purifier, comprise motor rear cover 1, carbon brush fixing frame 2 and wire seal plug 3 is integrated as a whole with motor rear cover 1, wherein carbon brush fixing frame 2 centered by the axis hole of motor rear cover 1 circumference uniform distribution on motor rear cover 1; The outside of described carbon brush fixing frame 2 is provided with the carbon brush fixed head stopper slot consisted of L shaped boss 4 correspondences; The cuboid cavity structure that described carbon brush fixing frame 2 connects for both sides, the upper surface of carbon brush fixing frame 2 is provided with a slot; Being provided with a pair of axial semicircle orifice in described wire seal plug 3, in axial direction successively decreases in the aperture of each semicircle orifice.The utility model is analyzed and is optimized by the structure to carbon brush fixing frame, enables to realize design and the processing of mould.
With reference to Fig. 1 assembly method of the present utility model, be: carbon brush is assembled from the outer edge side of carbon brush fixing frame 2.The outer edge side of carbon brush fixing frame 2 also is provided with carbon brush fixed head stopper slot, and this carbon brush fixed head stopper slot can play two effects with coordinating of carbon brush fixed head: the one, and the intensity of increase carbon brush fixing frame 2, prevent distortion; The 2nd, the carbon brush whip is played to slip-off preventing and spacing effect.Then connecting line on the carbon brush whip utilizes screw that it is fastened on the cylinder of motor rear cover 1 together with being crimped on by binding post with electric wire.Finally, electric wire passes motor rear cover 1 by wire seal plug 3, thereby completes the assembly work of whole motor rear cover 1.The endoporus of wire seal plug 3 has certain gradient, interior large outer little.Electric wire is easier to while passing from large mouthful, when passing from osculum, can be subject to certain extruding force, thereby realizes the fixation to electric wire.
