Abstract
The utility model relates to a direct current vacuum air pump. The direct current vacuum air pump is provided with a direct current motor, a transmission mechanism, and a cylinder. The direct current motor (1) and the cylinder (7) are mutually and vertically installed on the same shell body (4). A piston (8) of the cylinder is driven by the direct current motor (1) through a transmission gear (2), a connecting shaft (3), and a cam (5) to do reciprocating movement to carry out air suction and exhaust. An exhaust port (9) is provided with two air outlet joints. One air outlet joint is used for inflating, and the other joint (15) is used for being connected with a pressure gauge to display the inflating pressure. The direct current vacuum air pump has simple and compact structure, and small form. Even if the direct current vacuum air pump is arranged in a special box whose size like a portable cipher box, and the occupy volume of the direct current vacuum air pump is less than one third. The direct current vacuum air pump is very convenient for being carried by vehicles of an automobile, a motorcycle, etc. The direct current vacuum air pump solves the problem that tires of vehicles are inflated at any time and at any places.
Description
A kind of DC vacuum air pump belongs to the electric air pump to tyre inflation, is specially adapted to automobile, motorcycle and carries with car and can directly use DC electrical source on the car to give the DC vacuum air pump of tyre inflation.
The tire of vehicle needs often to go inflation to the special gas-filling station that is provided with.When vehicle driving at the deserted mountain wilderness, when finding under-pressure tyre, seek gas-filling station and but become a difficult matter.The present domestic portable electric charger of providing for oneself on the car that still finds no.
The utility model task provides in the special-purpose case that very little can the putting into of a kind of build resemble size the portable combination lock, and the DC vacuum air pump that can carry and use with car.
The utility model is that following technological scheme is finished: the Portable DC vacuum air pump, comprise housing, direct current generator, driving mechanism and cylinder, direct current generator and cylinder are vertically mounted on the same described housing mutually, described driving mechanism comprises: establish the driving gear engagement on gear and the connecting shaft on the motor, establish cam on the connecting shaft and cylinder column is hinged, pad one seal ring between the cylinder cap of described cylinder and the cylinder sleeve, directly be fixed on the housing with screw then, the cylinder cap of cylinder is provided with suction port, relief opening and radiating fin, be provided with the metal spring leaf of the unidirectional air inlet of control in the suction port, be provided with the rubber stopper and the spring of the unidirectional exhaust of control in the relief opening.
Establish two air outlet adapters on relief opening, a joint is used for inflation, and another joint is used to connect barometer to show inflation pressure.
The utility model has the advantages that simple and compact for structure, build is very little, even be placed in the special-purpose case that resembles size the portable combination lock, shared volume is less than 1/3rd, direct current generator can directly use the DC electrical source on the car, carry and use very conveniently with car, so just can solve the inflation problem of vehicle tyre whenever and wherever possible.
The utility model has following accompanying drawing:
Fig. 1 is the structural drawing of the DC vacuum air pump that provides of the utility model
Fig. 2 is the worm's eye view of cylinder head
Fig. 3 is the sectional view of cylinder head
Fig. 4 is the plan view of cylinder head
Fig. 5 is the cam front view
Further describe embodiment below in conjunction with accompanying drawing
DC vacuum air pump is made up of direct current generator, cylinder, driving mechanism and housing, cylinder 7 is installed in housing 4 tops, direct current generator 1 is installed in the sidepiece of housing 4, they vertically mutually vertical, the centre constitutes driving mechanism by driving gear 2, connecting shaft 3, cam 5, and the two ends of piston rod 6 become the circle shape, connects piston 8 and cam 5 with pin respectively, when motor rotation, drive reciprocating motion of the pistons by driving mechanism.Pad one seal ring 14 passes three screws on the cylinder cap with three pieces of screws then between the cylinder cap 11 of cylinder and the cylinder sleeve 7, directly cylinder 11,7 is fixed on the housing 4.Cylinder cap 11 is provided with suction port 10, relief opening 9 and radiating fin 19.Oval-shaped metal spring leaf 13 1 ends are fixed on the cylinder cap 11 with rivet, cover suction port 10, are used to control unidirectional air inlet.Relief opening 9, with a rubber stopper 18 and the unidirectional exhaust of spring 17 controls, relief opening 9 is provided with two air outlet adapters 15,16, and joint 16 is used for inflation, and joint 15 is used to connect barometer, to show inflation pressure.
Claims (2)
1, a kind of Portable DC vacuum air pump, comprise housing, direct current generator, driving mechanism and cylinder, it is characterized in that, direct current generator (1) and cylinder (7) are vertically mounted on the same described housing (4) mutually, described driving mechanism comprises: establish driving gear (2) engagement on a gear and the connecting shaft (3) on the motor (1), it is hinged with the piston rod (6) of cylinder to establish cam (5) on the connecting shaft (3), pad one seal ring (14) between cylinder cap of described cylinder (11) and the cylinder sleeve (7), use screw (12) directly to be fixed on the housing (4) then, the cylinder cap of cylinder (11) is provided with suction port (10), relief opening (9) and radiating fin (19), be provided with the metal spring leaf (13) of the unidirectional air inlet of control in the suction port (10), be provided with the rubber stopper (18) and the spring (17) of the unidirectional exhaust of control in the relief opening (9).
2, DC vacuum air pump as claimed in claim 1 is characterized in that, the relief opening of cylinder (9) is provided with two air outlet adapters.
