In addition, for convenience of explanation, the same portions as those of the conventional examples shown in the third figure will be denoted by the same reference numerals. The first drawing is a top view of the small pump 1 of the present invention, and the second drawing is a cross-sectional view taken along line A-A of the first drawing. In the figure, the 'small Lipu 1 series has a pump casing 3 formed as a top plate of the pump casing 2, a lower pump casing 4 integrally connected to the lower periphery of the upper casing 3, and a lower portion of the lower casing 4 and The motor casing 5 is integrally fitted to the side wall 5 a of the motor casing 5, and the diaphragm 2 and the rocker are housed in the casing κ of the small pumping body constituting the casing 5 and 13 200907174 Body 2 6 and motor 6. The space between the pump casing 3 and the diaphragm 24 is used as the pump chamber 23 to fix the suction and discharge of the air. Further, on the pump casing 3 side of the diaphragm 24, an exhaust valve body 3 is provided, and on the side of the damper body 26 of the diaphragm 24, an intake valve body 28 is provided. Then, the habitat limb Jb is operated by the driving of the motor 6, and the upper and lower movements of the hammer 26 cause the pump chamber 23 to be compressed and expanded to obtain the spring output. That is, when the oscillating body 26 vibrates toward the upper casing 3 side, the spring chamber 23 is dusted. At this time, the exhaust valve body 38 is opened to discharge the exhausted air (fluid) in the fruit chamber 23 from the exhaust hole 36. When the opposite A moving body 26 vibrates toward the motor side, the pump chamber 23 expands. At this time, the intake valve body 28 is opened, and the air is sucked into the pump chamber 23 through the air introduction hole 27a. By repeating such a series of actions, a certain output as a fruit can be obtained, for example, being applied to a fuel cell system (not shown). In addition

Ϊ ' ' ' As described above, 'shows the Α-Α line section of the pump 1 of the present invention, in the 貘 2 2 The center portion of the bottom portion of the bottom portion of the door 4 is formed in the door through hole 2, and then the suction valve 2 is formed which is opened to the center of the door and has a body 28 to constitute the intake valve portion. The 8 series is provided by cutting a portion of the diaphragm 24 from. "And the valve body 14 200907174 On the other hand, the shaft body 27 having the air introduction hole 27a communicating with the through hole 29 is protruded from the periphery of the rocking body 26. On the other hand, a cylindrical hollow-shaped mounting body 25 is protruded from the bottom surface of the diaphragm 24, and the hollow-shaped mounting body 25 is closely fitted to the aforementioned protruding body of the oscillating body 26 The outer side surface of the shaft body 27, and the suction valve portion V! formed at the bottom of the diaphragm 24 is in contact with the upper surface of the shaft body 27, and the diaphragm 24 is attached to the rocking body 26, It is constructed to perform pumping operation for small pump 1. Further, as shown in the third diagram of the conventional example, the oscillating body 26 is provided with a long-axis rotary drive shaft 3 3 from the motor 39, and then a rotary body is fixed to the upper end portion of the rotary drive shaft 33. 3, the eccentric rotating shaft 30 on the rotating body 34 is engaged with the center of the oscillating body 26, and the present invention does not have the aforementioned rotating drive shaft 3 3 and the rotating body as shown in the second figure. 3 4. That is, the lower end portion of the rotary drive shaft 33 constituting the present invention is fitted over the rotor 6a of the motor 6 and is eccentric with the motor shaft 6b to perform the rocking action of the oscillating body 26 . Further, in the present invention, since the pump portion P and the motor portion are provided in the same space portion of the casing, the rotary drive shaft 33 for connecting the pump portion and the motor portion is not required. And the rotating body 34, and thus the excess space required for the constitutions becomes unnecessary. Then, in the present invention, in order to form the same space portion, the pump casing 2 provided with the pump portion P and the motor casing 5 provided with the motor portion 合 are joined and integrated, and the same space portion 形成 is formed. Further, in the present embodiment, the pump casing 2 is integrally formed with a lower pump casing 4 for forming a side wall of the pump casing 2 under the peripheral portion of the upper pump casing 3 for forming a top plate, and the lower pump casing 4 lower end portion is extended to the bottom plate 15 of the motor casing 5 200907174 5 b upper 'at the same time the lower portion of the lower chestnut shell 4 reaches the side wall above the periphery of the bottom plate 5 b of the outer casing 5 ^ has two domains and two Integral, then, make the 哕; the lateral side of the outer side of the soil a is formed as a single p ΙΓ 'the side wall of the 2 and the side of the motor casing 5 is the same as the front side of the shell wall K - the space part In the case of A, the motor portion can be omitted, and the above-described two-part combination can be omitted, and the work axis and the pick-up rotation drive peak based on the conventional example are not required; The rotation drive linkage mechanism also contributes to the reduction of the motor portion and the pump portion of the present portion. The division of the shaft body 27 provided on the insert body 26 is flat +, U-shaped I-shaped. The recessed portion 2 7 of the diaphragm 24 is prevented from falling off. In the case of the hollow-shaped mounting body 25 provided on the diaphragm 24, the lower portion of the hollow-shaped mounting body 25 is lower, and the hollow-shaped mounting body 25 is provided with a projection 25a that can be coupled to the recess-preventing recess 27b. . In this way, it is provided that the protrusion portion 2 7 b is fitted with the protrusion portion 2 5 a = the anti-falling position, and the diaphragm 2 is made of the (four) body 2, so the system is strong. When the diaphragm 24 is moved by the rocking motion of the oscillating body 2 6 , the hollow body 25 of the diaphragm 24 is detached from the shaft body 27 . Therefore, there is no case where the air-tight performance of the suction chamber is lowered, and sufficient air is directed toward the pump chamber 2 to secure an appropriate I-pulse output. Moreover, since the upper shaft height of the hollow shaft mounting body 25 is lower than that of the shaft body 27 and the shaft body 27, the aforementioned cymbal and the motor casing are combined to each other. Miniaturized small pump. 16 200907174 Furthermore, the symbol 9 in the second figure is the stator of the motor 6, which is wound with a coil. Further, on the upper surface of the rotor 6a, the pulley 10 directly fixed to the motor shaft 7 is integrally provided with the rotor 6a, and therefore, the pulley 10 is formed as if a part of the rotor 6a is formed, and The lower end portion of the eccentric rotating shaft 30 is fitted on one side of the pulley 10, and the swinging body 26 is configured to swing according to the eccentric rotation of the eccentric rotating shaft 30 to perform the pumping operation. Further, the symbol 1 1 is a circuit board provided on the motor unit ,, and the circuit board 11 is mounted with various electronic components. Further, reference numeral 1 2 in the figure denotes a bearing.
