A contact panel 76 is disposed below the terminals 72. The contact panel 76 is made of a variety of conductive materials. The contact panel 76 is preferably in the form of a hollow dish 130697.doc 200918411. Contacts 77a and 77b are formed in the contact panel 76 to elastically support the terminals 72 and respectively contact them. These contacts 77a and 77b are a leaf spring. The contact panel 76 is secured to an upper portion of a body 82 of a slider 70 by a screw to a contact panel fastening portion. The slider 70 includes a cylindrical body 82 and a slide bar 80 that is coupled to the center of the upper side of the body 82. Engagement projections 83a and 83b are provided at the bottom of the main body 82. At the same time, a first annular engagement groove 8 1 3 and a second annular engagement groove 8 1 b are respectively disposed on the side surfaces of the slider 8 and the main body 82, a first ring 78a and a first Two rings 78b are correspondingly fitted into the engaging grooves. The outer cover 86 is disposed below the slider 70. A central perforated cylindrical spring mounting portion 90 is disposed at the center of the spring cover 86, and engaging projection slots 92a and 92b are formed on the sides of the spring mounting portion 9''. In addition, the outer cover 86 has an outer cover mounting projection 88 that is formed to extend laterally. The outer cover mounting projection 88 is fitted into the outer cover fastening hole 89 formed in the main body 42 of the pressure switch unit such that the outer cover 86 is fixedly mounted to the pressure switch unit main body 42. The engaging projections 83a and 83b of the slider 70 are respectively engaged into the engaging projection slots 92a and 92b of the outer cover 86. • A spring 94 is mounted between the slider 70 and the outer cover 86. Referring to Figure 7, in a normal mode, the slider 7 is resiliently supported by the spring, and the contact panel 76 forms a contact with the terminals 72. Therefore, if the start switch 62 is operated, electric power is supplied to the motor 52 of the vacuum pump 5. If the air in the vacuum vessel 52 is discharged to the outside according to the activation of the vacuum pump 5, the pressure in the cap 16 is gradually lowered. If the pressure 130697.doc • 12-200918411 is lowered below a predetermined pressure, the slider 7 can be lowered against an elastic force of the spring 94. Referring to Figure 8, if the slider 7 is lowered, the contact panel 76 also descends and separates from the terminals 72. Accordingly, the electric power supplied to the motor 52 of the vacuum fruit 50 is cut off, and the motor 52 is stopped. Next, this configuration of the vacuum pump 50 will be described in detail. Figure 9 is an exploded perspective view of a vacuum pump in the vacuum suction device according to this embodiment of the present invention. Fig. 1(a) is a perspective view showing a state in which an air enthalpy and a guide ring are coupled to each other in the vacuum pump of the vacuum suction device according to the embodiment of the present invention. Figure 1 〇 (b) is a bottom view of the air enthalpy. Figure 10 (c) is a perspective view of the guide ring. Figure 5 is a diagram showing one of the air intake operation (a) and the exhaust operation (b) of the vacuum pump of the vacuum suction device according to this embodiment of the present invention. The vacuum pump 50 includes the motor 52 and the pump casing 54. The pump casing 54 is formed by successively assembling a first outer casing 54a, a second outer casing 5, an air cymbal 150, and a second outer peripheral 54c. A joint bolt 164 is attached to the third outer casing 54c. The joint bolts 164 are successively passed through the air dam 15 and the second outer casing 54b and are coupled to the first outer casing 54a. A fixing member 100 and a rolling disk 11 are disposed in the first housing 54a. The fixture 100 is coupled to the drive shaft of the motor 52. A skew pin 1 〇 2 is disposed at an upper end of the fixing member 100 so as to be placed apart from a center of rotation by a predetermined distance and obliquely toward the center of rotation. The rolling disk 110 has an insertion hole U2 formed at a lower center thereof and a laterally extending actuating blade 114. The actuating wings U4 are provided to coincide with the number of diaphragms 122 as described below. The oblique pin 1〇2 of the fixing member is fitted into the insertion hole 112 by the fitting 130697.doc -13·200918411, so that the rolling disk 110 is eccentrically vibrated in a vertical direction according to the rotation of the fixing member 100, that is, If an actuating wing is at a suitable angle based on the center of rotation of the scroll disk 110, the remaining actuating wings will be tilted based on the center of rotation, thereby compressing or expanding the actuating wings that are coupled to the beta-roller disk 110. The diaphragms 122 of 114. Through holes i 丨 8 into which the diaphragms 122 are inserted are formed in the second outer casing 54b. The actuating projections 124 of the individual diaphragms 122 pass through the ρ through holes 118 ′ and are correspondingly fitted to the actuating projections formed in the separate actuating wings 114 of the rolling disk 110 In the slot 116. The diaphragm unit 120 includes a plurality of diaphragms 122, preferably three diaphragms 122, as shown in FIG. Each of the actuation projections 124 is coupled to a respective diaphragm 122' such that a chamber 126 is formed in the diaphragm bore 22. An exhaust valve 128 is provided at the center of the upper side of the diaphragm unit 120, that is, at the center of the diaphragm 122. A guide ring 130 is disposed above the chamber 126 and is fitted into a guide ring slot 134. The guide ring slot 134 is formed at the bottom of the air cymbal 150. An intake valve 140 is disposed in the chamber 126 of the diaphragm 122. The diaphragms 122, the exhaust valves 128, and the intake valves 140 are made of a flexible material so that they can be easily deformed by an external force. The guide ring 130 has an exhaust path 132' as shown in FIG. 10(c). Therefore, if the diaphragm 122 is reduced, the air inside passes through the exhaust path 132 along the exhaust path 132. The gas valve 128 is also discharged to an exhaust port 152. Meanwhile, if the diaphragm 122 is enlarged, air is sucked along one of the inlet ports 160 formed in the third casing 54c and is passed along the intake valve 140 along a groove formed in the upper portion of the air cymbal 150. 154 flows into the chamber 126. The inlet port 160 130697.doc • 14- 200918411 is connected to the suction conduit 46 of the pressure switch unit 40. The exhaust port 152 of the air enthalpy 150 extends to the outside via an exhaust vent exposed hole 162 formed in the third outer casing 54c. An exhaust ring 1 5 8 is mounted to the circumference of the exhaust port 152. Referring to Fig. 11, when the rolling disk 11 is rotated, an intake operation (a) and an exhaust operation (b) are successively generated. At the same time, preferably, a hub 17 formed at the bottom of the second casing 54b is in contact with the center of the rolling disk 11 (i.e., supporting the central portion of the rolling disk 110).
