[0012] Figure 1 It is a schematic cross-sectional structural diagram of Example 1.

[0013] Figure 2 It is a schematic cross-sectional view of the structure of Example 2. DETAILED DESCRIPTION

[0014] In order to make the technical solution of the utility model clearer, the following Figures 1 to 2 It should be understood that the specific implementation methods described in this specification are only for explaining the utility model, and are not intended to limit the protection scope of the utility model. Example 1

[0015] like Figure 1 As shown, a push-type suction cup anti-falling cup includes a cup body 1, and a suction cup 2 is arranged at the bottom of the cup body 1. The suction cup 2 is made of soft material with elastic deformation, such as silicone, rubber and other materials. It is a prior art and will not be repeated here.

[0016] A hollow accommodating chamber 11 is provided at the bottom of the cup body 1; the accommodating chamber 11 can be formed in the following two ways: one is to disassemble a hollow base at the bottom of the cup body 1 (by means of threaded connection or snap-on connection, etc.), and the base and the bottom of the cup body 1 form the accommodating chamber 11; the other is that the side wall of the cup body 1 continues to extend to form a bottom wall below the bottom, and a bottom cover is disassembled at the bottom end of the bottom wall, and the bottom cover, the bottom wall and the bottom of the cup body 1 form the accommodating chamber 11.

[0017] The suction cup 2 is in the shape of a trumpet with a small top and a large bottom, and has a suction cup inner cavity 21 . The suction cup inner cavity 21 is detachably disposed below the outer portion of the accommodating cavity 11 , and the suction cup inner cavity 21 is communicated with the accommodating cavity 11 .

[0018] In order to facilitate the control of the air pressure in the suction cup inner cavity 21 , a valve assembly is provided in the accommodating cavity 11 for opening or blocking the communication channel between the suction cup inner cavity 21 and the accommodating cavity 11 .

[0019] A first installation cavity 12 is disposed in the accommodating cavity 11 , the valve assembly is installed in the first installation cavity 12 , and the suction cup inner cavity 21 is communicated with the first installation cavity 12 .

[0020] A plug mounting hole and a first connecting hole 122 are respectively provided on the corresponding two side walls of the first mounting cavity 12; a button hole is provided on the side wall of the accommodating cavity 11, and the plug mounting hole, the first connecting hole 122 and the button hole are coaxially arranged; the valve assembly controls the opening or blocking of the connecting channel between the suction cup inner cavity 21 and the accommodating cavity 11 by opening and closing the first connecting hole 122.

[0021] A plug 7 is detachably provided in the plug installation hole, and the detachable manner may be threaded connection, or may be snap-connected or plug-in connected.

[0022] The valve assembly includes a connecting rod 4, a first spring 5 and a sealing member 6; a limiting portion 41 is provided on the connecting rod 4, the first spring 5 is sleeved on one end of the connecting rod 4 and clamped between the limiting portion 41 and the end of the plug 7; the sealing member 6 is sleeved on the connecting rod 4 and placed between the limiting portion 41 and the first connecting hole 122, for closing the first connecting hole 122.

[0023] An avoidance hole 71 is provided at the end of the plug 7 opposite to the connecting rod 4. The inner diameter of the avoidance hole 71 matches the outer diameter of the connecting rod 4. Specifically, the inner diameter of the avoidance hole 71 is larger than the outer diameter of the connecting rod 4, so that the connecting rod 4 can extend into the avoidance hole 71 during movement.

[0024] In this embodiment, one end of the connecting rod 4 away from the first spring 5 extends toward the key hole and is connected to the key 3, so that the key 3 can move inward and outward in the key hole.

[0025] When using:

[0026] 1. The cup is placed on the table, and the weight of the cup and the water squeezes the suction cup 2. The air in the suction cup cavity 21 is squeezed out through the gap between the suction cup 2 and the table. The suction cup 2 is close to the table. At this time, the air pressure in the suction cup cavity 21 is much lower than the external air pressure. The air pressure difference between the inside and outside of the suction cup cavity 21 makes the suction cup firmly attached to the table. Alternatively, the cup is placed on the table, and the button 3 can be pressed at the same time. At this time, the air in the suction cup cavity 21 can also be accelerated to be discharged through the first installation cavity 12, the first connecting hole 122 and the button hole in sequence.

[0027] 2. When the cup needs to be picked up, the button 3 is pressed, the connecting rod 4 overcomes the elastic force of the first spring 5 and moves inward, and one end of the connecting rod 4 extends into the avoidance hole 71, the sealing member 6 disengages and opens the first connecting hole 122, so that the suction cup cavity 21 is connected with the outside through the first mounting cavity 12, the first connecting hole 122 and the button hole in sequence, and the pressure difference between the inside and outside of the suction cup cavity 21 is eliminated, and the cup can be picked up smoothly at this time. Example 2

[0028] like Figure 2 As shown, on the basis of Example 1, a second installation cavity 14 is further provided in the accommodating cavity 11, the second installation cavity 14 is placed between the first installation cavity 12 and the button hole and is connected with the button hole, and a second connecting hole 141 coaxially arranged with the button hole is provided at one end of the second installation cavity 14 away from the button hole.

[0029] The key 3 of this embodiment includes a key end 31 and a key connecting rod 32. The key end 31 passes through the key hole, and the key connecting rod 32 passes through the second installation cavity 14 and passes through the second connecting hole 141 to abut against the end of the connecting rod 4; and a second spring 8 is sleeved on the key connecting rod 32 and clamped between the key end 31 and the second connecting hole 141 to provide a restoring force for the key 3; the end of the key connecting rod 32 passing through the second connecting hole 141 is also removably provided with a stopper 9, and the stopper 9 is used to limit the key 3 from being separated from the second installation cavity 14.

[0030] By pressing the button end 31 of the button 3 and compressing and overcoming the elastic force of the second spring 8, the button connecting rod 32 of the button 3 forces the connecting rod 4 to move inward, compressing it and overcoming the elastic force of the first spring 5. The sealing member 6 can then detach and open the first connecting hole 122. The suction cup inner cavity 21 can then be connected to the outside through the first mounting cavity 12, the first connecting hole 122, the second connecting hole 141, the second connecting hole 14 and the button hole in sequence, thereby eliminating the air pressure difference.
