Description of the Related Art Conventionally, in ordinary households and places where many people gather, it has been practiced to raise ornamental fish in an aquarium to raise them as indoor accessories or to delight the eyes of the viewer. . In the aquarium that breeds such appreciation fish, it is often found that a bubble generating device is often placed on the bottom of the water and air is sent to this bubble generating device from a small air pump to generate air bubbles. As a valve device for this type of air pump, the present inventor has already proposed a valve device in which a rubber tongue-shaped valve element is provided on a single supporting portion having one supporting leg (Japanese Utility Model Publication No. 51-76012), Also, a valve device in which continuous support pieces are provided on both sides of a rubber thin plate valve plate and support legs are provided on both support pieces (Actually published No. Sho 51-76).
No. 011) is proposed. However, when a valve with such a shape was prototyped and inspected, the former had only one support leg when inserting the support leg into the supporting small hole, so the valve plate swung left and right about the support leg and the position was Although it is not completely determined and the valve plate may rotate during use for a long time to reduce the valve operating efficiency, and the latter has the advantage of completely determining the valve plate position, the pump during use The drawbacks that the sound became very loud were recognized respectively. As an improvement plan for this, a valve device such as Japanese Utility Model Laid-Open No. 53-102108 was proposed. This valve device is provided with a cylindrical wall with a valve body insertion opening on one side and a notch on one side wall at a valve seat portion of an intake port and an exhaust port communicating with a pump chamber of a pump body of an air pump. In addition, a valve body fitting portion having a crocodile is provided at the cutout edge of the tubular wall, and the valve body is formed integrally with the thin wall tongue piece by a thin material tongue piece and a flexible material, and has a thickness of A thick-walled piece support portion tapered in the direction, the valve body is press-fitted to the valve seat portion of the pump body, and the suction port and the discharge port are covered with thin-walled tongue-shaped valve plates, respectively. It will be. Then, as the air flows through the intake port and the exhaust port, the thin tongue-shaped piece flexes and deforms to open and close the intake port and the exhaust port, thereby performing air intake and exhaust.

いという不具合もあった。However, in the air pump valve device improved in the above-mentioned conventional art, the problems that the prior art had had could be solved to some extent. , Still, the sound when the valve device opens and closes during use, i.e., a rattling sound is heard as a pumping noise and is harsh. May interfere with sleep. Furthermore, since bubbles are originally formed in the aquarium, the sound of bubbles rising in water or the clear sound of bubbles popping up to the surface of the water may be audible to the human ear. However, there was a problem that these sounds were inaudible because they were drowned out by the roaring sounds of the air pump.

閉に伴うポンプ音の発生は防止される。According to the present invention, the valve pressing member abuts on the base portion of the valve plate so as to press and fix the valve plate such that the tongue portion can be flexibly deformed by the flow of air. An edge portion from one curved edge to a straight edge to the other curved edge extends across the boundary between the tongue and the base of the valve plate. At the edge portion of the valve pressing member, the straight edge extends obliquely, so that the tongue portion of the valve plate is pressed and fixed obliquely with respect to the longitudinal direction thereof, whereby the tongue portion is fixed to the air. When the flow action of the air is weakened, it returns and descends with a twisting motion from the side to the closed position of the partition member. In this way, since the vertical movement of the tongue portion is twisted when the valve body is opened and closed, the tongue portion does not hit the valve seat portion of the partition member, and the generation of the pump noise accompanying the opening and closing of the valve is prevented.

相俟って、弁装置からの音の発生は殆ど起こらない。The operation of the valve device of the air pump having the above structure will be described. When the air pump is turned on and the air pump is operated, the magnet 11 reciprocates together with the arm 10 by the driving action of the electromagnetic drive mechanism 6, and the diaphragm 1 expands and contracts accordingly, thereby sucking air. And discharge operation. At this time, the valve plate 15 is opened and closed by the valve seat portions 13a and 13b so that the air can pass through the intake port 5a or the exhaust port 5b. In the opening / closing operation of the valve plate 15, as described above, the edges 19, 20 of the valve pressing member 16 are formed such that the linear edge 19 extends obliquely between the curved edges 20a, 20b. Base 17 and tongue 1
Since the boundary portion with 8 is pressed and fixed obliquely with respect to the longitudinal direction of the tongue portion 18, the tongue portion 18 is twisted from the portion corresponding to the side curved edge 20b by the action of air flow. When the air flow action is weakened, the portion corresponding to the side curved edge 20a is twisted to return and descend to return to the closed position of the drum member 3. In particular, since both ends of the straight edge 19 are curved edges 20, the tongue portion 18 starts to flex slowly at the start of the opening operation of the valve plate 15, and then the flexural deformation laterally proceeds at an appropriate speed. At the end of the closing operation, the return descent of the tongue portion 18 is transmitted at an appropriate speed, and at the end, the closing operation is performed slowly. Therefore, in the opening / closing motion of the valve device, the opening / closing motion with the gradual movement and the twisting or twisting motion are combined with each other, and sound is hardly generated from the valve device.

This prevents the generation of pump noise. Then, the air discharged from the pump chamber 2 once enters the air retention chamber of the frame 22,
Then it is discharged from the pump.
