Is discharged from the space 30 between the peripheral wall 23b of the head cover 23 and the pump casing 3.

Next, a case where the multistage pump is used to suck air in the compression storage bag 2 will be described. As shown in FIG. 1, the compression bag 2 is provided with an air vent 36 having a valve body. The air vent 36 is a socket body 37 attached to the compression bag 2 and the socket 37. A cap body 38 screwed to the body 37 is provided, and by closing the air passage port formed in the socket body 37 by fastening the cap body 38, the air passage port is opened by loosening it. It has become. A fitting groove 39 into which the suction port portion 12 of the pump casing 3 is fitted is formed at the tip of the cap body 38.

First, after closing the opening 2 a of the compression storage bag 2 shown in FIG. 6, the suction port 12 of the multi-stage pump 1 is attached to the cap body 38 provided in the air vent 36 of the compression storage bag 2. While being fitted in the annular groove 39, the electric motor 7 is driven to rotate the impeller 5. Since the impellers 5 are respectively arranged on both sides of the electric motor 7, it is possible to obtain a predetermined pumping capacity sufficiently, and further, since the rotating shafts can be shortened, the free ends of the rotating shafts 7a and 7b can be obtained. Even when the bearing is not supported on the side, vibration when driving the electric motor 7 can be reduced, and noise is also prevented because the partition walls 8 and 8a are formed integrally with the casing bodies 3a and 3b. The number of parts can be reduced.

When each impeller 5 is rotated by the electric motor 7, the air in the compression storage bag 2 is sucked into the pump casing 3 from the suction port 13 and passes through one pump portion A as shown by an arrow to a space. The electric motor 7 is cooled when entering the space 11 and flowing through the space 11. When the electric motor 7 is cooled, it is preferable to provide a circulation hole in the casing of the electric motor 7 so that air is also circulated in the electric motor 7 to effectively cool the electric motor 7.

Further, by the other pump portion B, it is discharged from the discharge port 20 of the end wall 9b of the pump casing 3, is discharged from the opening hole 24 of the head cover 23 where the bolt 25 is not inserted, and is also the pump casing. The air is discharged toward the air vent 36 from the space 30 between the head cover 23 and the peripheral wall 23b of the head cover 23. By discharging the air in this way, after the articles to be stored are compressed, the cap body 38 of the storage bag 2 is fastened and the air communication port is closed to flatten the articles to be stored which are bulky. You can do it. When suctioning the storage bag 2 as in the above embodiment, the suction of the storage bag 2 is conventionally performed by a cleaner, which may damage the cleaner, but the multi-stage pump 1 is used as a dedicated tool. If you do, there is no such problem and it is very convenient.

It should be noted that the present invention is not limited to the above embodiment, and the number and shape of the impellers 5 provided on both sides of the electric motor 7 are not limited, and the impellers 5 may be rotatable. It suffices that at least one is provided on each side of the electric motor 7.

Moreover, in the above-described embodiment, the air is sucked from one side of the pump casing 3 and discharged to the other side. However, the suction ports are provided on both sides of the pump casing 3, and the discharge port is provided in the middle of the pump casing 3. A portion may be provided so that air is taken in from both sides of the pump casing 3 and discharged from the midway portion of the pump casing 3. Further, as shown in FIG. 5, an intake port 12 and an exhaust port 12a are provided on both sides of the multi-stage pump 1, and attachments 43, 43a are detachably attached to the respective ports 12, 12a to supply air. Alternatively, it may be discharged.

Next, FIG. 7 is a half-cut cross-sectional view showing another embodiment of the dedicated pump. In FIG. 7, reference numeral 45 denotes a cylindrical casing body, a part of which is projected as a rectangular case body 46, A power source (not shown) such as a plurality of batteries is built in the case body 46, and the electric motor is turned on and off by an external switch S.

Reference numeral 47 denotes a head cover externally fitted to the rear portion of the casing body 45. The head cover 47 has a surface wall 47a in which a plurality of discharge ports 49 are radially formed, and an inner wall surface of the head cover 47. Between the outer peripheral wall surface of the casing main body 45, a discharge port 53 having a gap is formed via a ridge 50 as shown in FIG.

Reference numeral 55 denotes an output shaft that extends to one end of an electric motor 56 that is internally mounted behind the casing body 45, and the boss portions 57a of five impellers 57 are externally fixed to the output shaft. The air is taken in from one side of the casing body 45 and discharged from the rear side of the other side.

Reference numeral 59 denotes a partition wall fitted between the impeller 57 and the inner peripheral wall surface of the casing main body 45, and an air passage 61 is formed between the partition wall 59 and the impeller 57.

In the case of compressing the storage bag 2 such as a squash using the dedicated pump having the above structure, the suction port portion 63 is fitted into the air bleed portion 36 of the storage bag 2 as in the above embodiment, and the suction port portion 63 is inserted. When the switch S is turned on, the electric motor 56 rotates, and the rotation of the output shaft 55 and the impeller 57 caused by the rotation of the motor 56 causes the air in the storage bag 2 to pass through the open air vent 36 and the suction port 63. Since it is discarded from the discharge ports 49 and 53 through the passage 61 in the casing body 45, the inside of the storage bag 2 is immediately compressed.

Therefore, as in the case of the above-described embodiment, the articles to be stored such as a bulky sack are simultaneously compressed as the storage bag 2 is compressed, and the entire bag 2 is flattened. It can be done without taking up any significant space.

As described above, by using the dedicated pump for the compression bag according to the present invention, the air venting operation of the conventional compression bag is very easy.

[0032]

[Effect of the device]

 As mentioned above, the present invention has been developed as a dedicated pump for compression bags, whereas the conventional compression bag was compressed using a vacuum cleaner, so the entire pump is compact and easy to carry. In addition, the compression work has become extremely simple and has achieved special effects.

Moreover, the pump itself is provided with a plurality of impellers at both ends or one end of the output shaft of a power source such as an electric motor, and an air passage is formed between the casing main body and the impeller, so that suction is performed from the suction port. The compressed air can be exhausted easily and rapid intake is possible, which significantly shortens the time required for compressing the bag, and can obtain various effects such as constant exhaust capacity.

In particular, when the impellers are provided at both ends of the output shaft, the output shaft is not extended, and as a result, the bearing of the extension shaft is not required and the inertia moment of the rotating body is reduced. It has special effects such as reduction of motor load, reduction of vibration due to improvement of rotation balance, and elimination of energy loss due to friction of bearing.
