Abstract

The utility model discloses an air pump, which comprises a pump body and a motor, wherein the pump body is provided with an air inlet valve, an air outlet valve and a packing cup. The air pump is characterized in that an output shaft of the motor is opposite to the center of the packing cup, the output shaft of the motor and the packing cup are provided with a first permanent magnet and a second permanent magnet respectively, and inner field directions of the first permanent magnet and the second permanent magnet are both perpendicular to the output shaft of the motor. Due to a fact that the motor drives the first permanent magnet to rotate, a periodic attraction and repulsion is caused between the first permanent magnet and the second permanent magnet to drive the packing cup to compress and relax, thereby reducing mechanical vibration, improving efficiency, and being applicable to alternating current motors and direct current motors.

Description

A kind of aeration pump

Technical field

The utility model relates to the aeration pump technology, is the aeration pump technology that is used for aquarium specifically.

Background technique

The aeration pump that is used for aquarium of prior art generally is directly to use the alternating magnetic field of 50 hertz civil power DM generation directly to promote compressor pump work, and its shortcoming is that mechanical vibration produce bigger noise; It then is to utilize direct current generator to come work through the compression cylinder that crank drives the band piston that part is utilized the direct current aeration pump, and its deficiency is that the to-and-fro motion of piston in cylinder produces friction and wasted energy, and efficient is lower.

Summary of the invention

The purpose of this utility model is: a kind of use interchange is proposed, direct current generator all can drive, and the high aeration pump structure of efficient, overcome the deficiencies in the prior art.

For realizing the purpose of this utility model, realize by the following technical solutions: comprise the pump housing that has suction valve, gas outlet valve and leather cup, also has motor, it is characterized in that: the output shaft of described motor is relative with the center of leather cup, be respectively arranged with first permanent magnet and second permanent magnet on the output shaft of motor and the leather cup, and the magnetic direction of first permanent magnet and the second permanent magnet inside is all vertical with the output shaft of motor.

Compared with prior art, the beneficial effects of the utility model are: owing to adopt driven by motor first permanent magnet to rotate, make win permanent magnet and the periodic attraction of second permanent magnet generation and repulsion drive leather cup compression and diastole, mechanical vibration have been reduced, improved efficient, and interchange, direct current generator are suitable for all.

Description of drawings

A kind of configuration state when Fig. 1 has illustrated pump body compression of the present utility model.

A kind of configuration state when Fig. 2 has illustrated pump housing diastole of the present utility model.

1: the pump housing; 11: gas outlet valve; 12: suction valve; 2: leather cup; 3: the second permanent magnets; 4: the first permanent magnets; 5: motor.

Embodiment

With reference to the accompanying drawings embodiment of the present utility model is made a detailed explanation below.

With reference to the accompanying drawings 1 and accompanying drawing 2 shown in, key of the present utility model is: comprise the pump housing 1 that has suction valve 12, gas outlet valve 11 and leather cup 2, also has motor 5, it is characterized in that: the output shaft of described motor 5 is relative with the center of leather cup 2, be respectively arranged with first permanent magnet 4 and second permanent magnet 3 on the output shaft of motor 5 and the leather cup 2, and first permanent magnet 4 is all vertical with the output shaft of motor 5 with the magnetic direction of second permanent magnet, 3 inside.

In the using process, as shown in Figure 1, when motor 5 turns to the magnetic direction of second permanent magnet 3 and first permanent magnet 4 when identical, first permanent magnet 4 and second permanent magnet 3 are mutually exclusive, second permanent magnet, 3 compression leather cups 2 deviate from the direction motion of motor 5, this moment, the pump housing 1 interior air pressure raise, and suction valve 12 closes, and gas outlet valve 11 leaves; As shown in Figure 2, the magnetic direction that turns to second permanent magnet 3 and first permanent magnet 4 when motor 5 is not simultaneously, first permanent magnet 4 and second permanent magnet 3 are attracted each other, second permanent magnet, 3 traction leather cups 2 are towards the direction motion of motor 5, this moment, the pump housing 1 interior air pressure reduced, suction valve 12 leaves, and gas outlet valve 11 closes.Above-mentioned two processes constantly circulate.

Claims

1. aeration pump, comprise the pump housing (1) that has suction valve (12), gas outlet valve (11) and leather cup (2), also has motor (5), it is characterized in that: the output shaft of described motor (5) is relative with the center of leather cup (2), be respectively arranged with first permanent magnet (4) and second permanent magnet (3) on the output shaft of motor (5) and the leather cup (2), and first permanent magnet (4) is all vertical with the output shaft of motor (5) with the magnetic direction of second permanent magnet (3) inside.
