Abstract
The utility model relates to a miniature water pump, comprising a miniature motor and a pump body. A seal cover is arranged at the outer side of the miniature motor, and a shaft seal device is arranged on a motor shaft. The utility model adopts the seal cover and an especial shaft seal structure, which makes the miniature motor in a seal state, and the structure of the whole pump is skillfully arranged. The utility model has the characteristics of tightness and no water leakage, being waterproof, which is suitable for all submerging, semi submerging, and other various conditions.
Description
The utility model belongs to water plug, and specifically it is a kind of micro pump.
Micro pump is mainly used in industrial art, sales exhibition model, teaching aid, toy etc., and kind is a lot.Application number is to have introduced a kind of small submersible pump in China's utility model patent prospectus of 87202696, and this pump is made up of motor and transparent water pump, and water pump is a Centrifugal water pump.This pump is not owing to consider sealing problem, and makes it to use as the semi-submersible type water pump.
The purpose of this utility model provides a kind of micro pump of favorable sealing property, uses under the various situations being suitable for.
The utility model achieves the goal by following structure.The utility model is made up of the micromachine and the pump housing, in the micromachine outside seal closure is arranged, and gland seal device is arranged on motor shaft.Can make whole motor be in sealing state like this.
Gland seal device of the present utility model can adopt following structures: the side of the micromachine axis hole on the pump housing in the pump housing is a trapezoidal hole and the silk mouth arranged, one inner baffle ring is arranged at the bottom of trapezoidal hole, filler is housed outside inner baffle ring, an outer baffle ring is arranged outside filler, a claw type compressing member that cooperates with trapezoidal hole silk mouth is arranged outside outer baffle ring.By tightening the claw type compressing member, can reach axle envelope effect preferably like this.Baffle ring can adopt the copper baffle ring, and filler can adopt malthoid filler etc.
Accompanying drawing has provided an embodiment of the present utility model.Further specify structure of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the utility model micromachine gland seal device enlarged diagram.
Among the figure, 1 is micromachine, pump case lid 4 and impeller 7 that its motor shaft 9 passes on the pump housing connect, on pump case lid 4, there is a seal closure 2 to cover micromachine 1, at the pump case lid is a pump housing shell 84 times, water intake 6 and water outlet 5 are arranged on it, and pump housing shell 8, pump case lid 4 and seal closure 2 are bound up by screw 3; Motor shaft 9 passes pump case and covered 4 o'clock, one gland seal device is arranged on it, it is to be a trapezoidal hole that has silk mouthful at the motor axis hole that pump case covers 4 inboards, an inner baffle ring 10 is arranged in the hole, filler 11 is housed outside it, an outer baffle ring 12 is arranged outside filler 11, a claw type compressing member 13 that cooperates with trapezoidal hole silk mouth is arranged outside outer baffle ring 12, can reach good axle envelope effect by tightening claw type compressing member 13.
The utility model has adopted seal closure and special shaft seal structure, make micromachine be in sealing state, and arranged dexterously whole pump structure, made to the utlity model has tight water-tight and waterproof characteristics, be suitable for entirely diving, use under half latent and other various conditions.
