When the control component controls the suction cup to adsorb to an external structure, and when the detection module detects that the air pressure in the suction cup reaches a value at which stable adsorption can be achieved, the control pump can be turned off. The one-way valve only allows the gas in the adsorption cavity to flow unidirectionally towards the control pump and does not allow reverse flow. Therefore, the suction cup can maintain a stable adsorption state. When the detection module detects that the air pressure in the suction cup is lower than a preset safety value, the control pump can be made to work again to extract the air in the adsorption cavity. This process is repeated so that the suction cup can stably adsorb to the desired adsorption position. Description of the Drawings

[0037] Please refer to FIGS. 1-5. The present disclosure provides a suction cup structure 10, which includes a suction cup 1 and a pneumatic control assembly 2. The suction cup 1 has a suction cavity 11. The pneumatic control assembly includes a control pump 21, a one-way valve 22, a detection module 23, and a connection assembly 24. The connection assembly 24 includes a first interface 241, a second interface 242, and a third interface 243. The first interface 241 is in communication with the suction cavity 11 of the suction cup 1. The second interface 242 is in communication with the detection module 23. The one-way valve 22 is disposed in communication between the third interface 243 and the control pump 21 to allow air to flow unidirectionally from the third interface 243 toward the control pump 22.

[0038] In the suction cup structure 10 provided in the present disclosure, the detection module 23 is in communication with the inside of the suction cavity 11 through the connection assembly 24 to be able to detect the air pressure in the suction cavity 11. When the control assembly 2 controls the suction cup 1 to adsorb to an external structure, and when it is detected by the detection module 23 that the air pressure in the suction cup 1 reaches a value at which stable adsorption can be achieved, the control pump 21 can be turned off. The check valve 22 only allows the gas in the suction cavity 11 to flow unidirectionally toward the control pump 21 and does not allow reverse flow. Therefore, the suction cup 1 can maintain a stable adsorption state. When the detection module 23 detects that the air pressure in the suction cup 1 is lower than a preset safety value, the control pump 21 can be made to work again to extract the air in the suction cavity 11. In this way, the suction cup 1 can stably adsorb to the desired adsorption position.

[0039] Please refer to Figures 1-5 , the suction cup structure 10 further includes a housing assembly 3. The housing assembly 3 is detachably connected to the suction cup 1 and has an opening 31. The connection assembly 24 is disposed inside the housing assembly 3 and is in communication with the suction cavity 11 through the first interface 241. Specifically, the suction cup 1 may be provided with an air extraction port 12, and the air in the suction cavity 11 flows to the connection assembly 24 through the air extraction port 12. The control pump 21 is disposed inside the housing assembly 3, is connected to one end of the connection assembly 24 away from the suction cavity 11, and is provided with a discharge pipe 215. The open end 21511 of the discharge pipe 215 is received in the opening 31.

[0040] During use, there may be water stains or accumulated water at the adsorption position. If the suction cup 1 adsorbs to this adsorption position and the suction cup 1 is activated, the control pump 21 starts to pump air. Under the suction effect, there may be a situation of spraying water mist at the exhaust port inside the suction cup 1, thereby making the electronic components wet and affecting the lifespan of the suction cup 1. In some cases, the user may wipe the adsorption position to wipe off the water stains or accumulated water. However, in actual situations, after the user wipes, there will still be a wet situation at the adsorption position, and the internal structure of the suction cup 1 is still affected by moisture.

[0041] The suction cup structure 10 in this article discharges water stains or accumulated water to the outer shell assembly 3 through the discharge pipe 215. When the suction cup 1 is controlled to adsorb to an external structure by controlling the pump 21, and there are water stains or accumulated water on the external structure, the pump 21 is controlled to evacuate the adsorption cavity 11 of the suction cup 1, so that the water stains or accumulated water can be inhaled into the connection assembly 24 together with the air. Further, the air with humidity can be discharged outside the outer shell assembly 3 of the suction cup structure 10 through the discharge pipe 215 via the opening 31, so that the internal structure of the suction cup 1 is less affected by the environment and has a moisture-proof function. Specifically, it can prevent the control board 5 inside the suction cup 1 from getting wet.

[0042] Please refer to Figure 4 , the connection assembly 24 further includes a plurality of connecting pipes 244. For the plurality of connecting pipes 244, the second pipe orifice 214 is connected to the detection module 23 through one of the connecting pipes 244, and the third interface 243 is connected to one end of the one-way valve 22 through one of the connecting pipes 244. The other end of the one-way valve 22 is connected to the first pipe orifice 213 of the cylinder block 212 through one of the connecting pipes 244. With such an arrangement, multiple structural elements can make full use of the space arrangement inside the outer shell assembly 3, and then the various structural elements can be connected through the connecting pipes 244. It is worth noting that the plurality of connecting pipes 244 can be flexible hoses to facilitate making full use of the space inside the outer shell assembly 3.

[0043] Please refer to Figure 2 , specifically, the control pump 21 includes a pump body 211 and a cylinder block 212 connected to each other. The cylinder block 212 has a first pipe orifice 213 and a second pipe orifice 214. The first pipe orifice 213 is connected to one end of the connection assembly 24 away from the adsorption cavity 11, and the second pipe orifice 214 is connected to the discharge pipe 215. After the pump body 211 is started, air extraction begins. Under the action of pressure, the air in the cavity of the suction cup 1 quickly enters the cylinder block 212, so that the suction cup 1 can adsorb quickly. On the other hand, the air in the cylinder block 212 can be discharged outside the outer shell assembly 3 through the discharge pipe 215 along the second pipe orifice 214.

[0044] Specifically, please refer to Figure 2, the discharge pipe 215 includes a first pipe 2151 and a connector 2152. The connector 2152 is disposed at the opening 31. The first pipe 2151 is connected to the cylinder block 212, and the open end 21511 is connected to the connector 2152. The connector 2152 can be stably installed in the opening 31. Specifically, the hole wall of the opening 31 can be snapped into the snap groove 21521 on the outer wall of the connector 2152 to achieve stable installation. On the other hand, the connector 2152 includes a mounting hole 21522, and the open end 21511 of the first pipe 2151 can be inserted into the mounting hole 21522. When the pump body 211 works, the air in the adsorption cavity 11 of the suction cup 1 reaches the inside of the cylinder block 212 along the connection assembly 24, so that a safe negative pressure can be achieved inside the suction cup 1, facilitating the adsorption of the suction cup 1. The air in the cylinder block 212 is discharged outside the housing assembly 3 along the second pipe orifice 214 and then from the open end 21511 of the first pipe 2151. With such a setting, during the operation of the suction cup 1, even if the use environment is humid, it can be discharged outside the shell along with the air flow, thereby protecting the structures inside the housing assembly 3 from moisture.

[0045] Specifically, the connector 2152 is an elastic connector 2152, made of elastic materials such as rubber, etc., so that it can be squeezed into the opening 31, causing the hole wall of the opening 31 to be snapped into the snap groove 21521. The first pipe 2151 is a flexible pipe, which is convenient for being press-fitted into the mounting hole 21522, can increase the sealing performance, and the setting of the flexible pipe enables the first pipe 2151 to adapt to the shape of the space inside the housing assembly 3 and can be bent more conveniently.

[0046] A limiting member 34 is provided inside the housing assembly 3. The limiting member has a limiting space 341, and the connection assembly 24 is accommodated in the limiting space 341. Specifically, the connection assembly can be a tee, and each interface of the tee can be clamped in the limiting space 341.

[0047] More specifically, the housing assembly 3 includes a housing 32 and a connecting member 33. The connecting member 33 is detachably connected to the suction cup 1 to form a receiving cavity 333 for accommodating the housing 32. The side of the connecting member 33 facing away from the suction cup 1 has at least one connection interface 331 for connecting external accessories. With such a setting, the suction cup structure 10 in this article can be extended to the ecological chain of various photographic accessories. For example, it can be extended to a vehicle-mounted shock-absorbing arm to mount and adsorb the vehicle-mounted shock-absorbing arm to a vehicle.

[0048] Specifically, the connecting member 33 has four support arms 332. The four support arms 332 are connected to the suction cup 1 by screws, so that a receiving cavity 333 is formed between the connecting member 33 and the side of the suction cup 1 facing away from the adsorption cavity 11. The housing 32 can be installed in the receiving cavity 333, and structures such as electronic components can be installed in the housing 32, making the entire suction cup 1 in a modular design, which is convenient for production and installation.

[0049] Specifically, the connection port is opened on the surface of the connecting member 33 facing away from the suction cup 1. Among them, the connection interface 331 includes at least one of a sprocket, a threaded interface, a NATO interface, a cold shoe interface, an Arca slide groove, and a Manfrotto slide groove; users can connect the suction cup structure 10 to different photographic accessories through different interfaces, so as to install the photographic accessories to the adsorption position. For example, a sports camera accessory can be installed on the suction cup 1 through the connection structure.

[0050] In some embodiments, the connection interface 331 is movably connected to the connecting member 33 on the side facing away from the suction cup 1 through a rotating shaft, and the connection interface 331 includes one of a pipe clamp, a Mitchell interface, and a quick release base. The quick release base can be any quick release base on the market, and will not be elaborated herein.

[0051] In some embodiments, please refer to Figures 2-4 , the suction cup structure 10 includes a power source 4 and a control board 5. The control pump 21 and the power source 4 are both arranged on the control board 5, and the power source 4 is used to supply power to the control pump 21 and the control board 5. In some embodiments, a power supply interface exposed on the housing can also be arranged on the control board 5 for the suction cup to have an external power source. A display screen 52, an indicator light 53, a communication interface, etc. can also be arranged on the housing 32.

[0052] Furthermore, the detection module 23 includes a control board 5 and a pressure sensor 51. The second interface 242 is communicated with the pressure sensor 51, and the pressure sensor 51 is electrically connected to the control board 5, so that the control board 5 can control the control pump 21 to close when it reaches the first preset value, and can control the control pump 21 to open again when the suction cup is lower than the second preset value. Among them, the range between the first preset value and the second preset value is the safe range of the suction cup. With such a setting, when the air pressure value of the suction cup 1 fluctuates around the first preset value, the control pump 51 will turn on and off repeatedly. Therefore, the setting of the detection module 23 in this article can protect the control pump 51 and improve the service life of the control pump. The first preset value and the second preset value in this article can be obtained through multiple tests.

[0053] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the concept of the present application using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
