DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiments. As shown in FIG. 1, a small air pump a is an air pump composed of a diaphragm type pump chamber driven by a battery-powered motor. The portion 1 and the suction inlet portion 2 are provided with a hose joint portion 3 capable of connecting either one of them to the operating side, and the other one is connected to a switching valve 4 which is in communication with the outside air.

As shown in FIG. 2 as an example, the switching valve 4 has discharge holes 5 and suction holes 6 which are fitted in the discharge port 1 and the suction port 2, respectively, in order to ensure airtightness. In addition, a seal tube 7 is fitted into both of them, and a support shaft 8 is integrally attached to the center of the center of both of them, and an adapter 9 is rotatably fitted to the support shaft 8. The communication holes 10 and 11 are opened in the same phase as the hole 5 and the suction hole 6, respectively, one communication hole 11 is guided to the hose joint opening portion 3, and the other communication hole 10 is communicated from the peripheral surface to the outside air. The rotary plate 14 is formed by joining both the communication holes 10 and 11 and a sealing material 13 having a through hole 12 of the same diameter in the same phase.

According to the switching valve 4 constructed as described above, if the communication hole 11 guided to the hose connection port 3 is communicated with the one discharge port part 1 by turning the turntable 14 with a finger, the other is provided. Of the suction port 2 is communicated with the communication hole 10 communicating with the outside air, and the discharge air is supplied to the operating side.
If the communication hole 11 guided to the hose joint port 3 is communicated with, the other discharge port 1 communicates with the communication hole 10 communicating with the outside air, and air suction is performed on the working side, and the sucked air is It is discharged from the discharge port portion 1 through the communication hole 10 to the outside air.

Therefore, it is also provided as a small air pump b as shown in FIG. 3, which is an air pump formed by driving a diaphragm type pump chamber with a motor driven by a battery power source. 1 and the suction port 2 are joined to the switching valve 4 of the above two alternatives, one end of the hose 15 is joined to the hose joining port 3 of the valve 4, and the gripping body 16 is joined to the other end. As shown in FIG. 4, a fitting head 18 having a communication hole 17 communicating with the hose 15 is joined to the grip body 16, and the suction head 19 as an operating element indicated by an imaginary line is attached to the fitting head 18. The cleaning tool 20 shown in FIG. 5 or the like is fitted and used.

That is, when the suction cup 19 is used, the switching valve 4 is turned to the suction port 2 side by turning the rotary disc 14, and when the cleaning tool 20 is used, the suction head 19 is moved from the fitting head 18. Removed, fitting portion 22 of cup-shaped storage body 21
Is externally fitted to the fitting head 18, the sponge 23 housed in the housing 21 is soaked with detergent, the rotary plate 14 of the switching valve 4 is turned to the discharge port 1 side, and the switch 24 is turned on to drive the pump. Then, the communication hole 1 communicating with the outside air of the turntable 14
The outside air sucked into the pump chamber from 0 through the suction hole 6 of the adapter 9 through the suction port 2 is guided to the hose joint 3 of the turntable 14 through the discharge port 1 through the discharge hole 5 of the adapter 9. It is guided by the hose 15 through the communication hole 11 and discharged from the sponge 23 so that it can be used with further improved bubbling.

By providing the switching valve 4 in this way, it is possible to switch to both discharge and suction with one touch, and the air pump used exclusively for supplying air to the aquarium is used for washing and washing the face when bathing. It can be diverted to later uses such as beauty. It should be noted that when the filter 25 is provided inside the fitting head 18, it is hygienic when it is used for suction such as beauty treatment.
