[0013] In the electric air pump described in claim 3, the air pipe is configured to be detachable, so that it can be separated from the main body and has a compact design. This improves portability and ease of handling when packed and transported as a product.

[0014] In the electric air pump described in claim 4, the nozzle at the end of the air pipe is replaceable depending on the object to which compressed air is to be supplied, so that air can be filled into any object.

[0015] In the electric air pump described in claim 5, a switch is provided on one surface of the case, and the switch is operated by pressing and holding the switch from the surface of the case toward the back for a predetermined period of time, so there is no risk of malfunction. [Brief description of the drawings]

[0016] [Figure 1] FIG. [Diagram 2] FIG. [Diagram 3] FIG. [Figure 4] FIG. [Diagram 5] FIG. [Figure 6] FIG. [Figure 7] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] As shown in Figures 1 to 7, the electric air pump of the present invention comprises a rechargeable battery, an air compression mechanism powered by battery power, and a case 1 which houses the battery and the air compression mechanism. A switch 2 for starting and stopping the air compression mechanism is provided on the outside of the case 1. The case is provided with an air passage 3 for supplying air to the air compression mechanism, and an air outlet 4 for sending out compressed air is provided on the outside of the case 1. An air pipe 5 is detachably attached to the air outlet 4, and compressed air is supplied via the air pipe 5 connected to the air outlet 4.

[0018] The case 1 is a resin housing having a thickness of about several mm, and houses a battery and an air compression mechanism inside the box shape. In this embodiment, the size of the case 1 is 35 mm in width, 75 mm in height, and 68 mm in depth. The size of the case 1 can be set within a range that ensures compactness. An air outlet 4 is formed at the top front of the case 1. This air outlet 4 protrudes forward from the main body by about 5 mm. A female thread is formed on the inside of the circular protrusion, and an air pipe 5 is connected to this female thread. The front, flat, bottom and side surfaces of the case are provided with air passages 3. These air passages have a large number of small holes 6 extending radially in three directions, and air is supplied to the air compression mechanism through the collection of these small holes 6. A terminal 7 for charging the battery is provided on the bottom of the case, and a strap insertion hole 8 is provided on the top of the case.

[0019] The battery is rechargeable and uses various types of secondary batteries with charging and discharging functions, such as lithium-ion batteries, nickel-metal hydride batteries, nickel-cadmium storage batteries, and nickel-zinc batteries.

[0020] The air compression mechanism (air pump) is a device that receives power from the battery, compresses the air, and expels the sucked air from an air outlet. Diaphragm, electromagnetic, piston, etc. types are used.

[0021] The air pipe 5 is a flexible pipe having a diameter of several mm, with a male thread 9 formed at its base for connection to the air outlet, and a nozzle connection part 10 formed at its tip. Various types of nozzles are provided and can be replaced depending on the object to be supplied, such as tires, balls, air cushions, rubber boats, etc.

[0022] A switch 2 is provided in the center of the back of the case. This switch 2 is flush with the rear surface of the case. When the switch 2 is pressed with a fingertip for a predetermined period of time (approximately 1 second), the air compression mechanism is activated and compressed air is discharged from the air outlet 4 through the air pipe 5 and nozzle. The switch 2 is made of a translucent resin, and when the switch is operated, a light inside the switch comes on and can be seen through the switch, indicating that the switch is operated.

[0023] Next, a method of using the electric air pump of the present invention will be described. The electric air pump of the present invention has a compact design and is therefore highly portable. When pumping air into vehicle tires or the like, an air pipe 5 is connected to the air outlet 4 of the main body. Here, the air outlet is formed with a female thread and the air pipe is formed with a male thread, so that they can be easily connected by mating these threaded portions and rotating them. The nozzle at the tip of the air pipe 5 is pressed against (or connected to) the air filling port of the tire, and the switch is operated with a fingertip. By pressing switch 2 for about 1 second, the electric air pump is activated and compressed air is discharged, passing through the air pipe and nozzle to fill the tire with air. After the specified amount of air has been filled, the nozzle is released and switch 2 is pressed again to stop the electric air pump. When inflating a ball, air cushion, rubber boat, etc. other than a tire, attach a corresponding nozzle and perform the above operation.

[0024] Although an embodiment of the present invention has been described above, the specific configuration of the present invention is not limited to this embodiment, and any changes in settings that do not deviate from the gist of the invention are also included in the present invention. For example, the shape, performance, type, etc. of the battery and air compression mechanism described in the above embodiment can be changed while still ensuring the compactness of the main body.
