Compared with correlation technique, the eccentric shaft of the utility model air pump tilts, connected moving coil is provided with side by side four cylinders, no matter which position eccentric mass forwards to, always has cylinder in compression and air-breathing, makes motor be in the working state of compression all the time, there is no the zero load of backhaul, the efficiency of motor is high, therefore energy-conservation and ensure that the continuity of air feed, makes air-flow more stable.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of the utility model air pump;
Fig. 2 is the enlarged view of the circled portion of air pump shown in Fig. 1; And
Fig. 3 is the sectional view of the air pump A-A along the line shown in Fig. 1.
[embodiment]
Refer to shown in Fig. 1 to Fig. 3, the utility model air pump comprises motor 1 and the cylinder that is connected with motor 1 combines 2.Cylinder combination 2 comprises cylinder block 3, the eccentric mass 4 be housed in cylinder block 3, moving coil 5, link assembly 6, cylinder 7 and piston 8 and the cylinder head 9 that is assembled on cylinder block 3.The utility model air pump is provided with four cylinders 7 and is symmetrical arranged side by side.Cylinder 7 is provided with the host cavity 70 of collecting piston 8.The first vent 91 and the second vent 92 that cylinder head 9 is provided with air outlet hole 93 and is communicated with host cavity 70.First vent 91 is in communication with the outside.Second vent 92 is communicated with air outlet hole 93.
Eccentric mass 4 retaining screw 41 is fixed on motor 1, eccentric mass 4 is provided with the eccentric shaft 42 be connected with moving coil 5, eccentric shaft 42 is obliquely installed, it is connected with moving coil 5 by bearing 43, therefore when eccentric mass 4 rotates, moving coil 5 does not rotate, but about the angle of eccentric mass 4 can be followed, teetertotter.Moving coil 5 is rounded, and it is connected with four link assemblies 6.Each link assembly 6 connects moving coil 5 and piston 8 respectively.Link assembly 6 connects moving coil 5 and piston 8, and along with moving up and down of moving coil 5, piston 8 just can horizontal reciprocating movement.Piston 8 is provided with piston ring 81.
The utility model air pump also comprises the air valve diaphragm 71 be assemblied between cylinder 7 and cylinder head 9.Air valve diaphragm 71 is provided with first end 72 and second end 73 relative with first end 72.First end 72 is for sealing the first vent 91, second end 73 for sealing the second vent 92.When air valve diaphragm 71 is in vertical state, first end 72 is adjacent to cylinder head 9 also and between cylinder 7 has the first gap 93; Second end 73 is adjacent to cylinder 7 and and has the second gap 94 between cylinder head 9.When link assembly 6 pulls piston 8 to move to the direction away from cylinder head 9, also and between cylinder 7 the first gap 93 is had because first end 72 is adjacent to cylinder head 9, the first end 72 of air valve diaphragm 71 just can move to the first gap 93, and ambient atmos enters cylinder 7 by the first vent 91; When link assembly 6 promotes piston 8 to during near the motion of the direction of cylinder head 9, also and between cylinder head 9 the second gap 94 is had because the second end 73 is adjacent to cylinder 7, second end 73 of air valve diaphragm 71 just can move to the second gap 94, gas enters air outlet hole 93 by the second vent 92, completes whole pressure of inspiration(Pi) compression process.
When the utility model air pump uses, motor 1 drives eccentric mass 4 to rotate, because the eccentric shaft 42 on eccentric mass 4 tilts, moving coil 5 is made to have an angle tilted, along with the continuous rotation of eccentric mass 4, due to the connection of link assembly 6, moving coil 5 also and then moves up and down, drive piston 8 to do horizontal compression motion, complete the process of air-breathing and compression.The eccentric shaft 42 of the utility model air pump tilts, connected moving coil 5 is provided with side by side four cylinders 7, no matter which position eccentric mass 4 forwards to, always there is cylinder 7 in compression and air-breathing, make motor 1 be in the working state of compression all the time, do not have the zero load of backhaul, the efficiency of motor is high, therefore energy-conservation and ensure that the continuity of air feed, make air-flow more stable; In addition, four cylinders 7 are symmetrical arranged side by side, make the continuous operation of air pump energy, decrease the vibrations of work, reduce noise simultaneously.
These are only preferred embodiment of the present utility model, other any improvement conversion done on the present embodiment basis also should not depart from the technical solution of the utility model.
