Air storage barrels are not arranged, so that the whole volume is reduced; and exhaust passages are directly connected with a spray gun by rubber and plastic pipe, so that the portable diaphragm air pump is more suitably carried by hands.
Description
Technical field
The utility model relates to pressure air producing equipment field, specifically refers to a kind of and air brushing rifle, the matching used portable portable barrier film air pump of air nail gun.
Background technique
The Portable small air compressor is that air pump has more widely application in the operations such as finishing, decoration, ad production.It mainly is to provide source of the gas to air brushing rifle, air nail gun etc.Because volume is little, lightweight, so conveniently moving is the engineer operation personnel's that deeply fitted up, decorate welcome.But because in the past mini air compressor majority all adopts piston type, noise is larger when therefore using, and weight still seems heavier comparatively speaking, so that the certain operations personnel wish noise is little, the portable air compressor that weight is lighter comes out.
Summary of the invention
The purpose of this utility model is: usefulness low noise, the portable diaphragm type air pump that volume is little, weight is lighter replace piston type air compressor, to use in the mobile operating that adapts to the engineerings such as outdoor finishing, decoration, ad production.
The technological scheme of the utility model technical solution problem is: portable barrier film air pump, comprise interconnected cylinder body and bonnet, be provided with motor and cylinder in described cylinder body and the bonnet, the rotor shaft end of described motor is designed to eccentric shaft, described eccentric shaft is provided with axle sleeve outward, described axle sleeve side is arranged with two connecting rods, and described cylinder body both sides are provided with cylinder cap, are provided with the air-storage chamber of sealing in the described cylinder cap.The exterior edge face of described two connecting rods is fixedly connected with has flexible diaphragm, and described diaphragm edge is clamped and formed by inboard wall of cylinder block bead and cylinder cap and is tightly connected.
Described diaphragm is provided with inlet hole, and described inlet hole is provided with one-way sucting valve.
Described air-storage chamber is connected with cylinder and is provided with one-way exhaust valve, and described air-storage chamber communicates with air outlet flue, and two air-storage chambers interconnect with UNICOM's tracheae.
Be provided with motor in the described bonnet, bonnet namely is the housing of motor in fact, and be connected with cylinder body, described motor is by stator, rotor forms, rotor shaft two ends at described rotor are equipped with bearing, and described bearing is placed in the bearing support that is located at cylinder body end face and bonnet centre, also is provided with the fan blade that cools on the described rotor shaft.
What the utility model was useful is: owing to replacing piston with diaphragm, not only make the weight saving of complete machine, and air pump noise when operation reduces greatly also; Besides motor is connected with main body, makes the volume-diminished of this product, and because not establishing gas storage barrel, air outlet flue directly is connected with the air brushing rifle with rubber plastic pipe, so be more suitable for portable carrying.

Embodiment
As depicted in figs. 1 and 2, the utility model is the small and exquisite portable barrier film air pump of a kind of volume, and it is that motor and cylinder are set in cylinder body and bonnet.Establish cylinder cap 21/22 in cylinder 15 both sides, establish the air-storage chamber 31/32 of sealing in the cylinder cap 21/22.Rotor shaft 11 ends of motor are designed to eccentric shaft 14, and at eccentric shaft 14 outer sheathed axle sleeves 13, these axle sleeve 13 bi-side are provided with two connecting rods 71/72 symmetrically.And the exterior edge face of two connecting rods 71/72 is fixedly connected with and has flexible diaphragm 61/62, and diaphragm 61/62 edge is clamped and formed by inboard wall of cylinder block bead and cylinder cap 21/22 and is tightly connected.Air-storage chamber 31/32 in cylinder cap 21/22 is connected with cylinder 15 and is provided with one-way exhaust valve 51/52, and air-storage chamber 31/32 is connected with air outlet flue 1.Be provided with suction port at diaphragm 61/62, suction port is provided with one-way sucting valve 41/42.Be provided with motor in bonnet 10, bonnet namely becomes electric machine casing, and is connected with cylinder body.Motor is comprised of stator 8, rotor 9, is provided with bearing at rotor shaft 11 two ends of rotor 9, and bearing is placed in the bearing support that is located at cylinder body end face and bonnet 10 centres, also is provided with the fan blade 12 that cools on the rotor shaft 11.
The machine is in when work, starting electrical machinery, rotor shaft 11 rotations of motor.Because rotor shaft 11 ends are eccentric shafts 14, thus peripheral axle sleeve 13 can and swing along with eccentric shaft 14 rotations, thereby promote 71/72 to-and-fro motion of two connecting rods.Because connecting rod 71/72 is connected in one with diaphragm 61/62, have flexible diaphragm 61/62 and therefore also make corresponding vibration, the air in the cylinder 15 is pushed to air-storage chamber 31/32.When connecting rod 71/72 was pushed diaphragm 61/62 to air-storage chamber 31/32 side, Aspirating valves 41/42 cut out, and outlet valve 51/52 is opened, and the air that is pushed enters air-storage chamber 31/32; When diaphragm 61/62 is pulled to cylinder 15 1 side by connecting rod 71/72, Aspirating valves 41/42 is opened, outlet valve 51/52 is closed, and cylinder 15 interior air enter between diaphragm 61/62 and the cylinder cap 21/22, and compressed air can not flow backwards because intercepted by outlet valve 51/52 in the air-storage chamber 31/32.When diaphragm 61/62 was pushed to air-storage chamber 31/32 side by connecting rod 71/72 again, air outlet valve 51/52 compressed and that process is opened entered air-storage chamber 31/32.Certainly, two connecting rods and diaphragm are alternate runs, and the temporary pressurized air in two air-storage chambers 31/32 communicates by UNICOM's tracheae 16.When using source of the gas, compressed air flows out from the air outlet flue 1 of air-storage chamber 31/32 side.Because this acc power is little, diaphragm 61/62 vibration frequency is relatively very fast, and for easy to carry, so the machine does not arrange gas storage barrel, the air-flow with certain pressure directly sprays from nozzle through the control hand valve of air brushing rifle or air nail gun.
