Of course, it is intended to reduce the cost of reducing the number of parts by simplifying the internal components, and to further improve the productivity by shortening the assembly process.

Such a prior application design (Application No. 2000-33167), the milking hole 100 is formed by fastening the suction tube 102 and the feeding bottle 107 to be covered on the mother's breast feeding part 110, and the internal space of the milking hole Connected to the intake and exhaust hole 106 on one side as a tube 109 is separated by a certain length, and the air filled in the internal space of the milking hole vacuum pump or release the vacuum pump as a repeat cycle of a constant cycle It consists of a vacuum pumping means 200 for milking periodically and a piston drive means 300 for performing the pumping operation of the vacuum pumping means.

The vacuum pumping means 200 of the illustrated embodiment is provided with a base plate 201 fastening and mounting the power supply unit 204 configured as a replacement battery 203 and 220V home AC voltage using the adapter 202 and The base plate includes a cylinder 208 supported and fixed by first and second fixing rings 206 and 207.

And it is provided in the cylinder and slides to provide a piston 209 for vacuum pumping the air in the cylinder, one end is fixed to the annular groove 211 provided on the outer peripheral surface of the piston and the other end is the cylinder and the first fixing ring Fit to the coupling portion of the to form a flexible sealing plate 212 to seal the space inside the cylinder.

However, in the above-described prior art design, the piston generating air pressure in the cylinder is driven as the mutual eccentric rotation distance between the rotating motor rotating as the driving motor and the reduction gear and the piston rod, thereby obtaining a strong driving force necessary for driving the piston. It was difficult to reduce the vacuum pumping efficiency slightly, and the structural weaknesses of the rigidity of the fastening fixed part of the piston driving means were exposed.

Therefore, the present invention was devised to improve the structural weaknesses of the prior application design, and its purpose is to use a worm gear and a rack gear for converting the rotational motion of the forward and reverse drive motors into linear reciprocating motions as piston driving means. The piston slides strongly inside the cylinder to generate the powerful air pressure required for milking, and transfers the power of the drive motor to the piston precisely and powerfully to increase the vacuum pumping efficiency and further improve the rigidity of the coupling part of the piston drive means. It is in Sikkim.
