TECHNICAL FIELD OF THE INVENTION

 The present invention relates to a pump for injecting air by rotating a fan, and in particular, in an air pump for injecting outside air used in an air injecting tent, a rubber boat, and an air mat, the power source is a combination of charging and dry batteries. In addition, the present invention relates to an air pump and its connecting tool that enable injection and discharge of air in a short time.

[0002]

[Prior art]

 Conventionally, when inflating a rubber boat, beach mat, etc., the mouth of the human body was put on the inlet and air was infused by utilizing the vital capacity of the human being. In addition, a bellows-type foot-operated air pump was used to inject outside air while moving the bellows up and down with the force of the foot.

[0003]

[Problems to be solved by the device]

 However, when injecting air using human vital capacity, there is a limit to the amount of air injected at one time, and it takes a lot of labor and time to inflate a large rubber boat or beach mat. Needed. Moreover, since the mouth of the human body must be brought into contact with the inlet, there was a problem in hygiene.

Even when a bellows-type foot-operated air pump is used, the amount of air injected at one time is relatively small. Therefore, it was necessary to move the bellows part up and down with the foot many times, which required more labor and time than necessary.

Further, since the conventional air injection type rubber boat, the beach mat, and the like have a small injection port and a valve that suppresses the reverse flow of air, it is also very difficult to discharge the existing air. Met.

In view of the above points, the present invention relates to an inflatable type rubber boat and beach mat, particularly to an air tent that forms a triangular shape by injecting air, an air pump used for the rubber boat and the air mat, It is possible to inject and discharge air in a short time, facilitate the switching of switches, and provide an air pump and its connecting tool that use both rechargeable and dry battery power sources. .

[0007]

[Means for Solving the Problems]

 According to the present invention, in order to achieve the above object, a pump main body including a cylindrical upper lid portion and a bottom portion is internally provided with a fan and a rechargeable and dry battery type power unit for rotating the fan at a high speed. In addition, a lid portion having a movable valve, a locking convex portion and an engaging portion, and a holding portion, which is installed in the sheet body and has a perforated wide air inlet, are openably and closably connected by a hinge.

BEST MODE FOR CARRYING OUT THE INVENTION

 The construction and operation of the air pump of the present invention and its connecting tool will be described with reference to FIGS. The pump main body 1 is composed of a cylindrical upper lid portion 10 and a bottom portion 20, a fan 30 mounted inside the main body 1, and a power unit 40 for rotating the fan 30 at a high speed.

A suction port 11 for sucking outside air is installed on the upper part of the upper lid part 10, and a battery housing part 12 for housing the dry battery 44 is installed on the side surface. Further, on the side surface of the upper lid portion 10, a cover 13 attached to the suction port 11 and a cover 14 attached to the opening portion 21 of the bottom portion 20 are attached.

The bottom portion 20 has a central portion formed with an opening portion 21 that is fitted into a pump connecting tool 50 described later. Engaging portions 22 that engage with the engaging protrusions 53 of the pump connecting tool 50 are provided at two opposing locations on the inner edge of the opening 21.

A convex portion 32 fixed to the rotation shaft of the motor 41 is provided at the center of the base portion 31 of the fan 30, and a plurality of curved fins 33 are spirally formed on the upper surface of the base portion 31. is set up.

A motor 41 is arranged by a holder 42 at a substantially central portion of the power unit 40, and a storage battery 43 that can be repeatedly charged and used and a replaceable dry battery 44 are provided around the motor 41. is set up. A line (not shown) for operating the motor 41 is wired so that the power of the storage battery 43 and the power of the dry battery 44 can be used together.

Next, the configuration of the pump connector main body 50 will be described. The pump connector 50 is installed on the seat body 70 such as an air tent. The pump connecting tool 50 is composed of a lid portion 51 and a holding portion 61, both of which are connected by a hinge 56 so as to be openable and closable.

At the central portion of the lid portion 51, there are a locking convex portion 52 fitted to the opening portion 21 of the bottom portion 20 of the pump body 1 and a substantially central portion that engages with the engaging portion 22 of the opening portion 21. The engagement protrusion 53 having a tapered shape is installed.

A movable valve 54 formed of an elastic member is arranged inside the locking projection 52. The movable valve 54 is composed of a hollow cylindrical portion 55, a disk-shaped portion 56, a central convex portion 57, and a reinforcing plate 58. Further, the tubular portion 55 is slidably fitted to the shaft portion 60, and a spring 59 is inserted between the tubular portion 55 and the shaft portion 60. The normally movable valve 54 is in contact with the inner surface of the lid 51 by the bias of the spring 59. In addition, a flexible member 60 is installed around the movable valve 54 to reduce contact with the holding portion 61.

The holding portion 61 is fixed to a frame body 62 installed on the sheet body 70, and a wide-mouthed air injection port 63 is perforated. An engagement holder 64 that fits with the lid 51 is installed at one end of the injection port 63.

Next, a method of using the air pump of the present invention and its connecting tool will be described with reference to FIGS. 4 (a) and 4 (b).

FIG. 4A shows a state in which the pump body 1 and the pump connector 50 are fitted together. When the opening 21 of the bottom 20 of the pump body 1 and the locking projection 52 of the lid 51 of the pump connector 50 are fitted together, the engagement of the pump connector 50 between the engaging portions 22 of the opening 21. The compound convex portion 53 is arranged. In this case, the switch 80 in the power unit 40 is in the released state.

After the fitting, when the pump body 1 is rotated, the engaging projection 53 provided on the locking projection 52 moves and pushes up the switch 80 to bring it into contact. When the switch 80 is connected, the motor 41 operates, the fan 30 rotates at high speed, and the outside air 81 is sucked into the pump body 1. The sucked outside air 81 pushes down the movable valve 54 and flows out into the seat body 70.

When the injection of the outside air 81 is completed, the pump main body 1 is further rotated to release the contact between the engaging convex portion 53 and the switch 80. When the contact of the switch 80 is released and the fan 30 is stopped, the movable valve 54 is pushed up by the urging of the internal air and the spring 59. Then, the movable valve 54 comes into contact with the inner surface of the lid portion 51 again, and stops the discharge of air.

The discharge of the internal outside air 81 can be easily performed by pushing the movable valve 54 with a finger or the like, or by opening the lid 51 of the connector 50.

[0022]

[Effect of device]

 As described above, the air pump and its connecting device of the present invention have the following effects by having the above-mentioned configuration.

Since the switch can be switched simply by rotating the pump body, it is easy to inject and release air. In addition, the power source for operating the motor is a rechargeable battery and a dry battery battery, so the range of applications and applications can be expanded, and cost can be reduced. Furthermore, since the air injection port is wide, the outside air can be injected and discharged in a short time.

The air pump and its connecting device of the present invention exert a more excellent effect when used in an air injecting tent, a rubber boat, and an air mat, which have a relatively large amount of air stored therein.
