In an electromagnetic vibration type diaphragm air pump that is operated by circularly shaped diaphragms (107) and (107a) attached to both ends of a), as shown in FIG. Pump chamber casings (105), (105a), (105) having a discharge valve (126)

から吐出される。When a commercial frequency power supply current is applied to the electromagnet, a magnetic field is generated in the space between the magnetic poles, and the magnetic field drives and vibrates the permanent magnet mounted in the middle of the drive lever. Along with this, diaphragms attached to both ends of the drive lever vibrate to compress and expand the air in the pump chamber. As the diaphragm vibrates, the suction valve and the discharge valve operate, and air flows into the pump chamber through the suction hole and is discharged through the discharge hole.

して作動する。A real example of such an electromagnetic vibration type air pump with a low discharge rate and a small discharge rate is obtained from an air pump that obtains a discharge rate of 3 liters per minute under a water pressure of 50 cm water depth.
2), (102a) dimension weight is 18mm × 13mm × 5mm volume,
It weighs about 5.5 gr, the outer diameter of diaphragms (107) and (107a) is 36 mmφ, and the natural frequency f 0 of the vibration system is 50 to 60 Hz, which works as a pump with good vibration efficiency in synchronization with the power supply frequency. To do.

も増大する。<Problems to be Solved by the Invention> When an attempt is made to increase the air pressure of the electromagnetic vibration type diaphragm air pump of the real value as described above, the diaphragm (107), (107
Since the diameter of the vibrating surface in a) must be increased to increase the vibration amplitude, the core thickness of the electromagnets (141), (142) must be increased to increase the driving force. Not only that, but the corresponding permanent magnet (10
2) and (102a) also have to have a large volume to increase the magnetic force, and therefore the weight of the permanent magnets (102) and (102a) also increases.

ム(107),(107a)の直径は従来の2.15倍即ち36mmφ
×2.15=77.5mm必要になる。Assuming that the output of the conventional electromagnetic vibration type diaphragm air pump is to be enlarged to discharge 30 / min of air under a water depth of 1.5 m as described above, the diaphragm (107), (107a) Has a diameter of 2.15 times that of the previous model, namely 36 mmφ
× 2.15 = 77.5mm is required.
一方において、ポンプの出力は吐出圧力と吐出風量の

このような振動系の固有振動数は、 となり、電源周波数から、低く外れてしまうので、共振
勢力を利用できず、効率が著しく低下し、ポンプ出力は
各部寸法を大きくとった割合には大きくならない。On the other hand, since the output of the pump is proportional to the product of the discharge pressure and the discharge air volume, it is necessary to increase the amount of the permanent magnet that is the drive source by a factor of 15, which is significantly large when attached to both ends of the vibration lever (103a). It becomes a vibration moment. That is,
The natural frequency of such a vibration system is Since the frequency deviates from the power supply frequency to a low level, the resonance force cannot be used, the efficiency is remarkably reduced, and the pump output does not increase to the proportion of the large size of each part.
このように、吐出能力を増大しようとして、各部の寸
法だけ大きくしても、種々の面で障害があって、目的を
達し得なかった。Thus, even if the size of each part is increased in an attempt to increase the ejection capacity, there are obstacles in various aspects and the purpose cannot be achieved.

Assuming that it is expanded as a long diameter (4r) oval shape, if you try to increase the discharge rate, the area of the diaphragm will increase by about 2.27 times and the weight will increase in proportion to it.
Since the permanent magnet must be large in order to increase the driving force, the natural frequency of the vibration system decreases, but the electromagnetic vibration type diaphragm air pump of the present invention has the natural frequency of the vibration system due to the above structure.

る。Next, in the present invention, the diaphragms (7), (7a)
The rigid piston plates (9) and (9a) sandwiching the diaphragm limit the movable range (vibration range) of the diaphragms (7) and (7a) to a small value, so that the diaphragms (7) and (7a) are kept while maintaining a large vibration area. The force acts in the direction of contraction to increase the natural frequency of the diaphragms (7) and (7a). Further, as shown in FIG. 2, the diaphragms (7), (7a) are attached to the edges of the pump casings (5), (5a) having an outer diameter slightly larger than the inner diameters of the oval diaphragms (7), (7a) of the present invention. ), The diaphragm (7),

坐屈を防止する。Further, in the present invention, the oval diaphragm (7),
Inside the annular projections (19) and (20) outside the vibrating section of (7a), which project from both sides of the peripheral edge of the vibrating section, a rigid diaphragm expansion ring (11) made of hard plastic or the like is provided inside the annular projection (19) outside of (20). ) Is attached, the casings (5) and (5a) and the expansion ring (11) are connected to the diaphragms (7) and (7a).
Will be worn while maintaining a high degree of tension, and will prevent the natural frequency from decreasing without relaxing over the long term during use. Since the expansion ring (11) is always strongly pressed by the contracting force of the diaphragms (7) and (7a) directed inward, in the portion having a large radius of curvature,
Since buckling deformation occurs and the original function is not fulfilled, a rib (12) for averaging the expansion force of the entire circumference is formed inside the ring (11) only in that part as shown in FIG. Prevent buckling.

In an electromagnetic vibration type diaphragm air pump which is operated by diaphragms (7) and (7a) attached to both ends of a lever (3a), a pump chamber casing (5) having a suction valve and a discharge valve constituting a pump chamber, The outer shape of (5a) and the diaphragms (7), (7a) are formed into an oval shape, and the annular protrusions (19) are formed on the outer outer edges of the diaphragms (7), (7a), and the inner circumference thereof is formed. A diaphragm expansion ring (11) with buckling prevention reinforcement ribs (12) along its long sides is attached to the inside, and it is approximately the same shape as the outer circumference of the diaphragms (7) and (7a), and has a small shape. Both sides are made by the piston plates (9) and (9a) that are formed into an oval shape. An air pressing portion is formed by the diaphragms (7) and (7a) between the diaphragm expansion ring (11) and the diaphragm expansion ring (11), which is attached to the center of the oval diaphragms (7) and (7a). The drive lever (3) is attached to the drive part of the diaphragm (7), (7a).
Electromagnetic vibration diaphragm air pump with a) fixed.
