Benefits of technology

"The present invention is an air pump that can inflate objects quickly and easily. It has a tube, a tappet assembly, a connector, and a nozzle head. The air pump can use a gas cartridge or move the tube and tappet assembly to pump air into the object. The gas cartridge can also be used as a handle to move the tube. The technical effects of this invention are its ability to quickly and easily inflate objects, making it a convenient and efficient tool for inflating objects."

Problems solved by technology

In addition, it is a troublesome work to change the position of the gas cartridge 8 from the first end 901 to the second end 902 of the air pump in order to use the gas cartridge 8 as a grip.

first embodiment

[0024]FIGS. 1 through 8 show an air pump 1 in accordance with the present invention including a tube 10, a tappet assembly 20, a connector 30, a nozzle head 40, and a flexible and resilient conduit 50. Moreover, the air pump 1 defines a longitudinal length between first and second ends 101 and 102 thereof, and the nozzle head 40 and the connector 30 are disposed at the first and second ends 101 and 102, respectively.

[0025]The tube 10 and the tappet assembly 20 are movably connected to each other. The tappet assembly 20 includes a plunger 21, a piston 22, a joint 23, a sleeve 24, and an adapter 25. The plunger 21 defines a longitudinal length between first and second ends thereof and is hollow. The piston 22 and the adapter 25 are joined at the first and second ends of the plunger 21, respectively. The sleeve 24 is disposed outside and surrounds the outer periphery of the plunger 21 and is joined thereto via the joint 23 which is disposed at the second end of the plunger 21. Furtherm...

second embodiment

[0029]FIGS. 9 through 13 show an air pump 4 in accordance with the present invention. The air pump 4 including a tube 60, a tappet assembly 70, a connector 80, and a nozzle head 90. Moreover, the air pump 4 defines a longitudinal length between first and second ends 401 and 402 thereof, and the nozzle head 90 and the connector 80 are disposed at the first and second ends 401 and 402, respectively. The tube 60 and the tappet assembly 70 are movably connected to each other. The tappet assembly 70 includes a plunger 71, an anti-reverse flow mechanism 72, and a piston 73. The plunger 71 includes a hollow inner plunger body 711 and a hollow outer plunger body 712, and the inner plunger body 711 is movably received in the outer plunger body 712. Additionally, the connector 80 defines a receiving section 81, a receptacle 82, and a passage 83, and includes a valve stem 84, and a cap 85. The receiving section 81, the receptacle 82, and the passage 83 are communicated with one another. The va...

Abstract

An air pump defines first and second ends and includes a tube, a tappet assembly movably connected to the tube, a connector joined to the tube and disposed at the second end of the air pump, and a nozzle head to which an object to be inflated by the air pump is engaged is disposed at the first end of the air pump. Moreover, the air pump is operable in a first mode where a gas cartridge is engaged with the connector and the object is inflated by the gas cartridge rapidly. Also, the air pump is operable in a second mode where the tube and the tappet are moved relatively for pumping air into the object. Additionally, the gas cartridge is useable as a handle gripped for causing the tube to move with respect to the tappet assembly.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an air pump and, in particular, to an air pump operable in one mode that it is operably moved to pump air into an object, and in another mode that a gas cartridge is equipped therewith for inflating the object rapidly.[0003]2. Description of the Related Art[0004]FIGS. 14 to 16 show an air pump kit including a gas cartridge 8 and an air pump 9. The air pump 9 includes a pump head at a first end 901 and a pumping assembly at a second end 902 thereof, respectively. The air pump further includes a tube 903, a plunger 904, and a nozzle 905. The plunger 904 is reciprocally moved for pumping air into an object connected to the air pump. The nozzle 905 is defined in the pump head and exposes to outside at a side of the pump head. Further, first and second threaded orifices 906 and 907 are defined in the first and second ends 901 and 902 of the air pump, respectively, and a valve stem 908 is disp...
