The present invention relates to a suction cup, and more particularly to a suction cup device that can be adsorbed to an adsorption member.

Referring to Fig. 1, a conventional suction cup device includes a suction cup member 1 for elastic deformation, a pressing member 2 connected to the suction cup member 1, and a cover member 3 provided on the outside of the suction member 1 and the pressing member 2. And a spring 4 that strikes between the outer cover member 3 and the pressing member 2. The chuck member 1 has a hollow cone shape in a natural state, and has a bottom surface 101 and a recess portion 102 formed by the bottom surface 101. When it is to be used, the chuck member 1 is attached to a suction surface, and an operator applies a pressing force to the pressing portion 2, so that the chuck member 1 is deformed into a flat shape, and the air originally present in the recess portion 102 It is extruded, that is, the bottom surface 101 and the adsorption surface are vacuumed (see Fig. 2).

The function of the spring 4 is to cause a reverse force between the cover member 3 and the pressing portion 2, and the peripheral edge of the cover member 3 can be used to generate the peripheral edge of the suction member 1 by the elastic force of the spring 4. Pressing action, but after a period of use, air may penetrate between the bottom surface 101 and the adsorption surface, and the elastic force of the spring 4 may cause the depth of the recess portion 102 to gradually increase, so that the suction cup member 1 is adsorbed. The adsorption force of the adsorption surface is deteriorated (as shown in FIG. 1), and if the operator can find it in time, the pressing portion 2 can be pressed again to deform the suction cup member 1 and then extrude the air to generate an adsorption force, if the operator does not If it can be found in time, the suction device may fall off from the adsorption surface.

A suction cup device composed of the above-described integral structure, and as shown in FIG. 8, the disk portion 11 of the chuck member 10 is flat before being used, and due to the gas storage chamber 13 and the gas storage space 35 The one-way valve 20 is in a free state with respect to the protrusion 12, and the floating member 32 is subjected to the elastic force of the elastic member 33, and is outwardly embossed relative to the positioning seat 31. The space 35 has a maximum volume and the stop portion 323 of the float member 32 is positioned relative to the baffle member 312. At this time, the airtight ring 45 is subjected to the elastic force of the elastic member 33, and is also supported by the second shoulder surface 421 toward the retaining ring member 312, and the second shoulder surface 421 and the airtight ring are Airtightness is formed between 45 (see Figure 10).

As shown in FIG. 9, when the suction cup device is to be used, the operator first abuts the abutting surface 111 of the chuck member 10 against the adsorbing member 100, and then the operator operates the housing unit 30, the manual exhausting The whole structure of the valve 40 and the like is rotated relative to the guide 50, and the guiding portions 317 can be guided by the guiding inclined surfaces 533 of the cam portions 53 so that the positioning seat 31 is opposite to the guiding axis along the axis L. The seat 50 generates a climbing effect, and the guide 50 is inserted into the convex protrusions 113 by the concave holes 511, so that the guide 50 can be positioned in a hoop direction with respect to the suction cup member 10. At this time, the protrusion 12 is pulled by the positioning plate 313, and is displaced along the axis L with respect to the disk portion 11, and because the circumference of the disk portion 11 is pressed by the guide 50, The region where the disk portion 11 is engaged with the ring wall 121 is elastically deformed, and the air pressure inside the air reservoir 13 is less than atmospheric pressure, and the disk portion 11 can be adsorbed on the adsorbing member 100. At this time, the airtight ring 45 is subjected to the elastic force of the elastic member 33, and is also supported by the second shoulder surface 421 toward the retaining ring member 312, and the second shoulder surface 421 and the airtight ring are Airtightness is formed between 45 (see Fig. 10), and the manual exhaust valve 40 is in a closed state.

Next, as shown in FIG. 11 , the imaginary line to the solid line and FIG. 12 , the operator applies a force to the end wall 322 of the floating member 32 because the friction between the airtight ring 45 and the first peripheral wall 311 is greater than a frictional force between the airtight ring 45 and the second peripheral wall 321 , so that when the floating member 32 is retracted into the first space 314 of the positioning seat 31 , the first shoulder surface of the first convex ring 41 When the 411 is kept against the airtight ring 45, a gap is generated between the second shoulder surface 421 and the airtight ring 45 (the manual exhaust valve 40 is in an open state), so that the gas is originally stored in the air. Air in the space 35 can flow along the exhaust flow path 36 and finally be released to the outside of the housing unit 30 through the through hole 315 (the air flow is as indicated by the arrow in Fig. 12). As shown by the solid line in FIG. 11 , the floating member 32 and the positioning seat 31 have a minimum volume. At this time, the elastic member 33 is in a compressed state and contains a rebound elastic force, and the airtight ring 45 is subjected to the same. The elastic force of the elastic member 33 is also supported by the second shoulder surface 421 toward the retaining ring member 312, and the air gap between the second shoulder surface 421 and the airtight ring 45 is formed (refer to FIG. 10). The manual exhaust valve 40 is again closed. During the retraction of the floating member 32 toward the first space 314 of the positioning seat 31, the valve piece 22 of the one-way valve 20 is pushed by the air of the air storage space 35, and is always affixed to the The outer side surface of the side wall 122 shields the vent holes 124, so that the space of the gas storage space 35 can be prevented from flowing toward the gas storage chamber 13.

As shown in FIG. 13, when the suction cup device is used for a period of time, external air may infiltrate between the disk portion 11 and the adsorbing member 100, causing the air pressure inside the gas storage chamber 13 to become larger due to the gas storage space. 35, the air storage chamber 13 has a vacuum function. When the air pressure inside the air storage chamber 13 is greater than the air pressure inside the air storage space 35, the air inside the air storage chamber 13 is immediately worn based on the pressure flattening action. The venting holes 124 are caused to flow toward the gas storage space 35. At the moment when the air passes through the venting holes 124 and flows to the gas storage space 35, the valve sheet 22 is pushed by the airflow relative to the side wall 122. A lift is generated to create a gap of air flow between the venting holes 124 and the valve plate 22. And when the air stored in the gas storage chamber 13 is absorbed in the gas storage space 35, the floating member 32 gradually becomes embossed toward the outside of the positioning seat 31, and the elastic force of the elastic member 33 acts, the second The second shoulder surface 421 of the collar 42 is held against the airtight ring 45 and the manual exhaust valve 40 is maintained in a closed state (shown in Figure 10).

When the operator sees the warning unit 60 from the outside of the housing unit 30 (refer to FIG. 9), it means that the degree of vacuum in the air storage space 35 is deteriorated, and only the floating member 32 has to be opposite to the positioning seat. 31 generates a press, which can be restored to the state of the solid line of Fig. 11, and the suction device can be prevented from falling off.

Therefore, the present suction cup device can produce the following effects:

1. The present invention utilizes the combination of the gas storage chamber 13, the check valve 20, the gas storage space 35 and the manual exhaust valve 40 to form two spaces for storing air, and is used for controlling the gas. The valve can ensure the stability of the suction cup device when it is sucked, and can solve the problem that the existing suction cup is easy to fall off. And by the pressure leveling action, the one-way valve 20 allows the air in the gas storage chamber 13 to be discharged only unidirectionally toward the gas storage space 35, and the manual exhaust valve 40 can be pressed by the floating member 32. The action is simultaneously operated from the closed state to the open state, and the air is smoothly discharged along the exhaust flow path 36 toward the outside of the housing unit 30, and the operation is relatively simple.

2. In the state of use, by the arrangement of the check valve 20, the air accumulated in the gas storage chamber 13 can be automatically released into the gas storage space 35, and the gas storage space 35 is used to have a variable volume. Characteristic, the air can be continuously stored, and with the setting of the manual exhaust valve 40, the user can extrude the air existing in the air storage space 35 at any time, and can ensure the suction member 10 and the adsorbing member 100. The airtightness is maintained therebetween, and it is not necessary to pick up the suction cup member 10 to re-operate away from the adsorbing member 100.

3. The elastic force of the elastic member 33 is not only capable of providing the floating member 32 to be pressed and approaching the suction cup member 10, but also has the ability to be opposite to the suction cup member 10 and to emboss relative to the positioning member 31. The tendency of the airtight ring 45 to remain against the second shoulder surface 421 can be provided to ensure that the manual exhaust valve 40 is often maintained in a closed state.

As shown in FIG. 14 and FIG. 15, the second embodiment of the present suction cup device also includes a suction cup member 70, a check valve 20, a cover unit 80, a manual exhaust valve 40 and a warning unit 90.

Each of the warning members 91 has a blocking portion 823 that is adjacent to the floating member 82 and is connected to the connecting end portion 911 of the floating member 82 and A movable end portion 912 opposite to the connecting end portion 911 and in a free state with respect to the floating member 82. As shown in FIG. 15, when the floating member 82 is embossed relative to the positioning seat 81, the movable end portions 912 are away from the floating member 82 and are in an unfolded state. As shown by the imaginary line of FIG. 15, when the floating member 82 is pressed and approaches the chuck member 70, the movable end portions 912 abut against the floating member 82. The warning unit 90 can be used to remind the user that the vacuum degree of the suction cup device is deteriorated.

As shown in FIG. 16, the third embodiment of the present invention is different from the second embodiment in that the warning unit 90' has a battery pack 91' disposed on the floating member 82, and is disposed on the floating device. The member 82 is electrically connected to the warning member 92' of the battery pack 91', a first conductor 93' disposed on the floating member 82 and electrically connected to the battery pack 91', and a first portion disposed on the positioning seat 81 and adjacent thereto In the second conductor 94' of a gas storage space 85, the warning member 92' is exposed outside the positioning seat 81, and the floating member 82 is pressed and retracted relative to the positioning seat 81, the first conductor 93 'The second conductor 94' is non-conducting (as shown by the phantom line in Fig. 16). When the floating member 82 is embossed relative to the positioning seat 81, the first conductor 93' and the second conductor 94' are electrically connected to each other, and the warning member 92' can emit an audible or bright light to generate an alarm. The warning unit 90' can also be used to remind the user that the vacuum degree of the suction cup device is deteriorated.

Further, as shown in Fig. 17, the fourth embodiment of the present type of suction cup device comprises a suction cup member 10', a check valve 20', a cover unit 30' and a manual exhaust valve 40'. The difference between the first embodiment and the first embodiment is that the housing unit 30' has a positioning base 31', a floating member 32' and an elastic member 33'. The elastic member 33' is disposed on the positioning seat 31'. Between the floating member 32', the positioning member 31', the floating member 32' and the elastic member 33' together form a gas storage space 35'. The elastic member 33' has a bellows shape, and the floating member 32' has An upper valve hole 325' having a valve member 41' mounted to the upper valve hole 325' and a spring 42 biased between the valve member 41' and the floating member 32' '. The fourth embodiment of the present invention can also achieve the same objects and effects as the first embodiment.
