The utility model has the efficiency that the exchange current and direct current are suitable to use to increase convenient use.

Description

DC or AC air pump

The utility model relates to a kind of automobile tire and inflates the inflating pump of usefulness, particularly relates to a kind of direct current that improves structure and exchanges dual-purpose inflating pump.

In the prior art, automobile tire is inflated the pump of usefulness, is one of most important driver's tool of automobile always, and it mainly is to drive a crank by a drive motor, drives the pneumatic cylinder piston to-and-fro motion by crank, and reaches the usefulness of inflation of tire.

Yet, automobile itself adopts direct current, therefore inflating pump also all is to use direct current to be driven, that is the socket of use cigarette lighter, so the tire pump of automobile driver's tool then can only be applicable on the automobile because of it uses power supply and socket to be subject to, and can't be applicable to other places and purposes.

The purpose of this utility model, be to provide a kind of direct current to exchange dual-purpose inflating pump, the rotor winding (that is armature) of its inflating pump drive motor has particular design with commutator, and constituted with the lead in collinear footpath not in the rotor winding, make big line footpath coil be the cladding shape, less line footpath coil is cladded in nexine, and connect with different commutators respectively, and by the selection of not collinear radial line circle of rotor winding and commutator, and have direct current and exchange the function that all is suitable for, promote the practicability on using.

The purpose of this utility model is achieved in that a kind of direct current exchanges dual-purpose inflating pump, comprise: have the pneumatic cylinder of a piston with the supply high-pressure air, and in order to drive a crank, crank drives the reciprocating drive motor of a pneumatic cylinder piston by this; This motor has a stator, to rotate input shaft, an and rotor that is coupled in described output shaft, it is characterized in that: described rotor has a magnetive cord, one is wound on the iron core and from first winding of direct current power supply unit supply electric energy, one be wound on the iron core and from AC power supply supply electric energy and with partly overlapping second winding of first winding, and the wire diameter of above-mentioned two windings and inequality; Described stator comprises at least one pair of continuously along the magnetic pole of described rotation input shaft; By this, drive motor can be connected in described DC power supply or AC power supply, to drive described pneumatic cylinder.

Wherein said first winding is to be wrapped in a suitable thickness on the iron core, and described second winding is wound in a suitable thickness on first winding again, and the line of second winding directly is directly also bigger than the line of first winding.

Be fixed with first commutator on the axis body of described rotor first end, be fixed with second commutator on the axis body of described rotor the second end, described first winding is to be connected on first commutator, and second winding is to be connected on second commutator, and two commutators and derive the both positive and negative polarity of direct current and AC power cord respectively by a brush, and it is linked to each other with the ac/dc power supply respectively.

The utility model also further comprises the teeth parts in order to be coupled described motor and pneumatic cylinder; Be located in the rotating shaft of rotor, in order to cooling off the fan of described motor, and a shell; Wherein said motor, teeth parts, fan all are arranged in the shell.

The utility model also further comprises and being coupled between teeth parts and the described pneumatic cylinder, in order to drive the connecting rod of pneumatic cylinder piston.

A kind of direct current of the utility model exchanges dual-purpose inflating pump, and its advantage and good effect are very tangible.Because it is to be provided with drive motor in the enclosure, drive a crank device and radiation fan by drive motor, and then the mat crank device drives a pneumatic cylinder piston to-and-fro motion again do the high pressure effect of inflating; The rotor winding of this drive motor is to become internal and external layer to coat mutually by the winding wire in collinear footpath not to form, make big line footpath lead loop be coated on less line footpath coil outer rim, and be connected in different commutators with lead respectively, and derive the use of direct currents and AC power cord applicable to both electric currents by different commutators.

Because the utility model is to be provided with a drive motor with radiation fan in the enclosure, by motor driven one gearwheel, drive the pneumatic cylinder piston to-and-fro motion by gearwheel with the eccentric manner drivening rod again, and reach the usefulness that high pressure or low pressure are inflated, and it more possesses AC and DC power supply effect all applicatory, the facility of using with increase.

The utility model is by the motor rotor winding of clad type, making the utility model can be suitable for car direct current power supply (DC electrical source of cigarette lighter socket) driving on automobile inflates, and can not be subjected to the restriction of automobile (cigarette lighter socket) DC electrical source, and drive inflating pump in other local ac power supplys of using, reached really and given the phase practical purpose.

Concrete structure of the present utility model, feature, effect are provided in detail by following embodiment and accompanying drawing thereof:

Fig. 1 is the utility model embodiment's a member action schematic representation.

Fig. 2 is the utility model embodiment's a rotor configuration schematic representation.

Fig. 3 is the utility model embodiment's a three-dimensional exploded view.

Fig. 4 is the utility model embodiment's a sectional view.

See also Fig. 1, the utility model mainly is to establish a drive motor 1 in the enclosure, and drive a gearwheel 11 with small gear 10 engagement of rotor-end, this gearwheel 11 is provided with a jack-post 12 in eccentric part, connect a connecting rod 13 by this jack-post 12 again, the take offence piston 15 of cylinder pressure 14 of connecting band, and pneumatic cylinder 14 is provided with inlet hole 19 and valve 20, air outlet 17 and valve 18, and piston 15 outer rims also are provided with oil sealing 16 and cylinder driving fit; And drive gearwheel 11 by drive motor 1, and by 13 driven plunger 15 to-and-fro motion in pneumatic cylinder 14 of eccentric jack-post 12 drivening rods, and suck low-pressure air from inlet hole 19, get pressurized gas by air outlet 17 again, and reach the usefulness that high pressure is inflated.

See also Fig. 2, Fig. 3, drive motor 1 is made of housing stator 31 and rotor 30, and rotor 30 1 ends drive gearwheel 11 with small gear 10 engagements, and the other end is established a radiation fan 320; The winding of its rotor 30 is that with the commutator 32 of lead 35 connection rotors 30 front ends, and commutator 32 is derived direct current supply line both positive and negative polarities (DC+ and DC-) with brush 33 after forming coil by less line lead 35 directly; Lead 35 outer rims in this less line footpath form the coil winding that is coated on outer rim with big line footpath lead 34 more in addition, the commutator 321 that connects rotor 30 rear ends more again with lead 34, derive AC power cord both positive and negative polarity (AC+ and AC-) by brush 331 again, and make this drive motor 1 be suitable for direct current and ac power supply.
