Abstract
The utility model relates to a portable inflation pump comprising a shell, a motor installed in the shell and a speed shifting mechanism in transmission connection with one end of an output shaft of the motor. The speed shifting mechanism is connected with an air compression device through a transmission mechanism, the other end of the output shaft of the motor is provided with a centrifugal fan, of which an air outlet is communicated with the outside, and a plurality of air inlets are arranged on the shell beside the air compression device, away from the centrifugal fan. With the portable inflation pump adopted, not only high pressure inflation of vehicle tires and large air quantity inflation of air cushion beds and other similar articles can be simultaneously implemented, but also separate inflation can be conducted. The portable inflation pump has the characteristics of simple structure, convenience in use, long service life and the like.
Description
Technical field
The utility model relates to a kind of electric aeration device, the especially a kind of portable aerating pump that can inflate article such as vehicle tyre, air beds.
Background technique
Existing portable aerating pump mainly is made of motor, gear, driving mechanism, gas compressing apparatus, its working principle is: motor is reciprocating in its cylinder by the piston that gear, driving mechanism drive in the gas compressing apparatus, the gas that enters cylinder is compressed, gas after the compression is discharged by outlet through one-way valve, and Chinese utility application specification (application number is 912047984) has been done disclosure to above-mentioned this class portable aerating pump structure.The inner gas pressure of this class gas-filled pump is higher, is fit to the inflation to vehicle tyre, yet the flow of inflation is less, and is oversize to the inflationtime of some article such as air bed, skin raft ship, is difficult to satisfy practical requirement.
Summary of the invention
At above-mentioned existing in prior technology problem, the purpose of this utility model provide a kind of both can be high-pressure aerated, flow inflation, simple in structure, long service life greatly again portable aerating pump.
Technical solution of the present utility model is: a kind of portable aerating pump, it comprises: a shell, a motor in the cased chamber, a gear that is in transmission connection with motor output shaft one end, this gear is connected with a gas compressing apparatus by a driving mechanism, the other end of described motor output shaft has a centrifugal blower, the exhaust outlet of centrifugal blower can communicate with the external world, has a plurality of inlet holes on the other casing wall away from centrifugal blower of gas compressing apparatus.When motor drives centrifugal blower and gas compressing apparatus running, gas compressing apparatus compresses the gas that enters in it on the one hand, acquisition can be filled the pressurized gas of tire, on the other hand under the centrifugal blower effect, air is inhaled into from the inlet hole of shell, and formation to the air-flow between the centrifugal blower intake grill, is brushed gas compressing apparatus and motor outer surface from inlet hole, thereby when obtaining the big air quantity gas of low pressure, gas compressing apparatus and motor are cooled off.
After adopting said structure, because the motor output shaft two ends drag centrifugal blower and gas compressing apparatus respectively, thereby this gas-filled pump has two kinds of functions high-pressure aerated and the big air quantity inflation of low pressure can outwards be provided simultaneously, to satisfy user's different needs; A plurality of inlet holes of opening on set centrifugal blower and the shell help the cooling to gas compressing apparatus and motor, thereby are prolonged the working life of gas-filled pump.In addition, the impeller of centrifugal blower can directly be fixed on the output shaft of motor, and is simple in structure, high working efficiency.
Description of drawings
Fig. 1 is the utility model portable aerating pump structure schematic representation.
Embodiment
As shown in Figure 1, the portable aerating pump has a shell 1, include a motor 2 in the inner chamber of shell 1, with the gear 4 that motor output shaft 3 one ends are in transmission connection, this gear is connected with a gas compressing apparatus 8 by a driving mechanism 7.Wherein gear 4 adopts train of reduction gears; Driving mechanism 7 is made of cammingly axis body 5 and connecting rod 6; Second one-way valve 14, air outlet 13 and pressure-display device (not shown) on gas compressing apparatus 8 main first one-way valves 12 by cylinder 9, cylinder head, piston 10, piston ring 11, the piston constitute, wherein pressure-display device can be a pressure gauge, also can above digital display device.
The other end at motor 2 output shafts 3 is equipped with a centrifugal blower 15, this centrifugal blower is made of spiral case 16, impeller 17, exhaust outlet 18, wherein impeller 17 directly gland on output shaft 3 ends of motor 2, exhaust outlet 18 communicates with the external world by the perforate on the shell 1, has the intake grill 18 of this blower fan at the axial location place of spiral case 16.
For reducing the temperature rise of motor 2 and 8 long periods of gas compressing apparatus operation, on gas compressing apparatus 8 sides and shell 1, have a plurality of inlet holes 20 away from centrifugal blower 15.During work, under centrifugal blower 15 pumping actions, ambient air is inhaled into from these inlet holes 20 on the shell 1, forms the air-flow that brushes gas compressing apparatus 8 and motor 2 outer surfaces, thereby take away its distribute heat, discharge by centrifugal blower 15 exhaust outlets 18 at last.
Convenience for use night can also be provided with the light source (not shown) on gas-filled pump.
The utility model portable aerating pump has and can implement high-pressure aerated and low pressure and mass flow simultaneously and inflate multiple function, thereby is the standby a kind of instruments of motor vehicle.
