Abstract
A matching structure of a motor housing, a rear cover and a pump body cover base used for a water purifier comprises the motor housing, the rear cover and the pump body cover base. The rear cover and the pump body cover base are arranged at the two ends of the motor housing. The rear cover and the pump body cover base are both provided with bumps which are matched with grooves in the two end faces of the motor housing; the two end faces of the motor housing extend outwards to form a plurality of buckling-pressing claws, and the rear cover and the pump body cover base are both provided with buckling-pressing grooves which are matched with the buckling-pressing claws. Through the improvement of the fastening and matching structure of the motor housing, the rear cover and the pump body cover base, the tightness of the connection among the three components is improved. In addition, the assembly structure is optimized, the connecting components are simplified, assembly efficiency is improved, product cost is reduced, assembly consistency is guaranteed, and broad market requirements can be satisfied.
Description
Technical field
The utility model relates to a kind of motor housing, the cooperating structure of motor housing and bonnet and pump housing cage for especially a kind of water purifier.
Background technique
Mainly being formed by parts such as motor, supercharging hydroecium and valves of diaphragm booster pump.And motor is the critical component of diaphragm booster pump as the motive force of suction booster.The quality of motor directly affects supercharging pump performance and life-span.
Traditional supercharging electric motor for pump comprises motor housing, magnetic shoe, pump housing cage and bonnet.It is fastening that the installation of motor needs two long spiro nails to carry out, and the bonnet screw outer end of screw from bonnet stretched into, and through the gap between two magnetic shoes, arrives the screw on pump housing cage, finally with nut, in the nut fixed groove inside of pump housing cage, carries out fastening.In this assembly process, because screw is longer, along with stretching into of long spiro nail, affected by the magnetic force of magnetic shoe, make screw stressed, the conducting direction of screw before and after making it to depart from.Manually be difficult in the outer end of bonnet, long spiro nail be stretched into, finally be difficult to make long spiro nail to be fitted into the screw inside on pump housing cage.Therefore serious impact efficiency of assembling.And long spiro nail passes from the gap between two magnetic shoes, also can affect the magnetic circuit trend in magnetic field, thereby affect the correlation properties of motor, cause the correlation properties of motor to reduce.
Summary of the invention
The utility model provides the cooperating structure of a kind of water purifier with motor housing and bonnet and pump housing cage, solved the Placement that conventional motors shell and bonnet and pump housing cage are used long spiro nail, thereby improved efficiency of assembling, and the stability while having guaranteed the motor operation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: the cooperating structure of motor housing and bonnet and pump housing cage for a kind of water purifier, comprise motor housing and be arranged on bonnet and the pump housing cage at motor housing two ends, on bonnet and pump housing cage, be equipped with the motor housing both ends of the surface on the projection that is complementary of groove; It is characterized in that: also be outward extended with a plurality of pawls of withholding on the both ends of the surface of described motor housing, be equipped with on described bonnet and pump housing cage and withhold the groove of withholding that pawl is complementary.
Beneficial effect: the utility model, by the improvement of the secure fit structure of motor housing and pump housing cage and bonnet, has improved three tightnesses that parts connect.And optimized assembly structure, simplified connected element, improved efficiency of assembling, reduced product cost, guaranteed the conformity of assembling, can meet wide market demands.
The accompanying drawing explanation
Fig. 1 is exploded perspective view of the present utility model.
In figure, 1 is motor housing, the 2nd, and bonnet, the 3rd, pump housing cage, the 4th, groove, the 5th, projection, the 6th, withhold pawl, the 7th, withhold groove, the 8th, magnetic shoe.
Embodiment
As shown in Figure 1, the cooperating structure of motor housing and bonnet and pump housing cage for a kind of water purifier, comprise motor housing 1 and be arranged on bonnet 2 and the pump housing cage 3 at motor housing 1 two ends, on bonnet 2 and pump housing cage 3, be equipped with motor housing 1 both ends of the surface on the projection 5 that is complementary of groove 4; Also be outward extended with a plurality of pawls 6 of withholding on the both ends of the surface of described motor housing 1, on described bonnet 2 and pump housing cage 3, be equipped with withhold that pawl 6 is complementary withhold groove 7.
