Abstract
Description
- The present invention relates generally to a pump, and more particularly to an air pump having an improved structure and assembly.
- A conventional air pump has an old style of assembly and complicated structure, and more particularly, the conventional air pump is consisted of a large amount of components and it is a hard job to assemble these components. A following drawback of that is the higher cost of fabrication. There is still no a fine solution to fix aforesaid drawbacks of the conventional air pump.
- The primary objective of the present invention is to provide an air pump, which has a new type of structure to reduce the numbers of components, make the process of assembly easier and faster and reduce the cost of fabrication.
- According to the objective of the present invention, an air pump, which is driven by a spindle of a motor, comprises a mount member having a main body and a chamber. An air bag set has a substrate, an air bag provided on the substrate, in which an air chamber is formed. The air bag has a bag bladder and a linking portion. An insulating plate has a plate member. An inlet and an outlet are communicated with the air chamber of the air bag set. A ventilation part has a pad member. An inlet valve is communicated with the inlet of the insulating plate and an outlet valve is communicated with the outlet of the insulating plate. An air guide device has a main member. An inlet is communicated with the inlet valve of the ventilation part and an outlet is communicated with the outlet valve of the ventilation part. A linking assembly has rotary base driven by the spindle of the motor for rotation and a linking portion connected to the linking portion of the air bag of the air bag set.

-
- As shown in FIGS, from FIG. 1 to FIG. 5, an air pump of the preferred embodiment of the present invention, which is driven by a spindle M1 of a motor M comprises:
- A
mount member 10 is consisted of afirst mount 11 and asecond mount 21. Thefirst mount 11 has amain body 13, abase 15, achamber 17 and fourcoupling portions 19. Thesecond mount 21 has amain body 23, fourpositioning recesses 24 on themain body 23, two surroundingmembers 25, two locatingposts 27 and fourcoupling portions 29. Thecoupling portions 29 are four through holes and aligned with thecoupling portions 19 of thefirst mount 11 respectively. The motor M is mounted on themount member 10 via twobolts 93. - An
air bag set 30 has asubstrate 31, four positioning plates 32 provided on thesubstrate 31 and received in thepositioning recesses 24 of themount member 10 respectively, twoair bags 33 provided on thesubstrate 31 and formed twoair chambers 35 therein. Eachair bag 33 has abag bladder 331, abag head 333 and a linkingportion 335 in sequence. - An
insulating plate 40 has aplate member 41, twoinlets 43, twooutlets 45, two locatingholes 47 to receive the locatingposts 27 of themount member 10 respectively and fourcoupling portions 49. - A
ventilation part 50 has apad member 51, twoinlet valves 53 and twooutlet valves 55 for theinlets 43 and theoutlets 45 of theinsulating plate 40 respectively, twosealing ribs 57 formed on a top side and a bottom side of thepad member 61 for surrounding and isolating saidinlet valve 53 and saidoutlet valve 55, and fourcoupling portions 69. - An
air guide device 60 has amain member 61, twoinlets 63, anair chamber 65, anair pipe 67 having anoutlet 68 therethrough and fourcoupling portions 69. - A linking
assembly 70 has arotary base 71 and abag linking device 81. Therotary base 71 has arotary member 73 driven by the spindle M 1 of the motor M for rotation and ashaft 75 tilted toward a center axis of therotary base 71. Thebag linking device 81 has ashaft portion 87, adisk 83, two linkingportions 85 and aball 89 received in theshaft portion 87. - Four
coupling devices 91 are inserted through thecoupling portions air guide device 60, theventilation part 50, theinsulating plate 40 and thesecond mount 21 and screwed to thecoupling portions 19 of themount member 10 respectively. - First, a hose (not shown in FIGS.) is connected to the
air pipe 67 of theair guide device 60. The spindle M1 of the motor M drives therotary base 71 of the linkingassembly 70 for rotation. Theshaft 75 of therotary base 71 drives thebag linking device 81 for rotation to move the linkingportions 335 of theair bags 33 of the air bag set 30 upwards and downwards via the linkingportions 85 of thebag linking device 81 respectively. - As shown in FIG. 3, in the meantime, air in the
air chamber 35 of theair bag set 30 is compressed and flows to the hose (not shown) via theoutlet 45 of theinsulating plate 40, theoutlet valve 55 of theventilation part 50, theair chamber 65 and theoutlet 68 of theguide device 60. - On the contrary, another
air bag 33 of the air bag set 30 sucks air into theair chamber 35 of the air bag set 30 from theinlet 63 of theair guide device 60 via theinlet valve 53 of theventilation part 50 and theinlet 43 of theinsulating plate 40. The air will be exhausted to the hose as described above in the next action. - FIG. 6 shows the
rotary base 71 is rotated 90 degrees. - As shown in FIG. 7, the
rotary base 71 rotates continuously to make theair bag 33 at right sucking air into theair chamber 35 from theinlet 63 of theair guide device 60 and theair bag 33 at left exhausting the air in theair chamber 35 out as described above. - The character of the present invention is that the air pump of the present invention is different from the conventional air pump in structure to meet the requirement of various sizes of the air pumps.
