[0040] Please refer to FIGS. 1-5. This document provides a suction cup structure 10, which includes a suction cup 1, a housing assembly 2, a connection assembly 3, and a control assembly 4. The suction cup 1 has a suction cavity 11; the housing assembly 2 is detachably connected to the suction cup 1 and has an opening 21; the connection assembly 3 is disposed inside the housing assembly 2 and communicates with the suction cavity 11; the control assembly 4 is disposed inside the housing assembly 2, connected to one end of the connection assembly 3 away from the suction cavity 11, and is provided with a first discharge pipe 41. The open end 411 of the first discharge pipe 41 is received in the opening 21.

[0041] During use, there may be water stains or accumulated water at the adsorption position. If the suction cup 1 adsorbs to this adsorption position, after the suction cup 1 is activated, the control assembly 4 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, which may cause the electronic components to get wet and affect 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 moisture and other situations at the adsorption position, and the internal structure of the suction cup 1 is still affected by moisture.

[0042] Specifically, the suction cup 1 may be provided with an air extraction port 12, and the air in the suction cavity 11 flows through the air extraction port 12 to the connection assembly 3.

[0043] This document provides a suction cup structure 10. By providing a first discharge pipe 41, the open end 411 of the first discharge pipe 41 is exposed outside the housing assembly 2. When the control assembly 4 controls the suction cup 1 to adsorb to an external structure and there are water stains or accumulated water on the external structure, the control assembly 4 pumps air from the suction cavity 11 of the suction cup 1, so that the water stains or accumulated water can be sucked into the connection assembly 3 together with the air. Further, the air with humidity can be discharged outside the housing assembly 2 of the suction cup structure 10 through the first discharge pipe 41 via the opening 21, 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 circuit board 6 inside the suction cup 1 from getting wet.

[0044] Please refer to Figure 2 Specifically, the control assembly 4 includes a control pump 42 and a pump housing 43 that are connected to each other. The pump housing 43 has a first interface 431 and a second interface 432. The first interface 431 is connected to one end of the connection assembly 3 away from the suction cavity 11, and the second interface 432 is connected to the first discharge pipe 41. After the control pump 42 is activated, it starts to pump air. Under the action of pressure, the air in the cavity of the suction cup 1 quickly enters the pump housing 43, so that the suction cup 1 can adsorb quickly. On the other hand, the air in the pump housing 43 can be discharged outside the housing assembly 2 through the first discharge pipe 41 along the second interface 432.

[0045] Specifically, please refer to Figure 2, the first discharge pipe 41 includes a first pipeline 412 and a connector 413. The connector 413 is disposed in the opening 21. The first pipeline 412 is connected to the control assembly 4, and the open end 411 is connected to the connector 413. The connector 413 can be stably installed in the opening 21. Specifically, the hole wall of the opening 21 can be clamped in the clamping groove 414 on the outer wall of the connector 413, so as to achieve stable installation. On the other hand, the connector 413 includes a mounting hole 415, and the open end 411 of the first pipeline 412 can be inserted into the mounting hole 415. When the control pump 42 works, the air in the adsorption cavity 11 of the suction cup 1 reaches the inside of the pump housing 43 along the connection assembly 3, so that a safe negative pressure can be achieved inside the suction cup 1, which is convenient for the suction cup 1 to adsorb. The air in the pump housing 43 is discharged outside the housing assembly 2 along the second interface 432 and then from the open end 411 of the first pipeline 412. 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, so as to prevent moisture from the structure inside the housing assembly 2.

[0046] Specifically, the connector 413 is an elastic connector 413, which is made of elastic materials such as rubber, etc., and is squeezed into the opening 21, so that the hole wall of the opening 21 is clamped in the clamping groove 414. The first pipeline 412 is a flexible pipe, which is convenient to be press-fitted into the mounting hole 415, can increase the sealing performance, and the setting of the flexible pipe can make the first pipeline 412 adapt to the shape of the space inside the housing assembly 2 and can be bent more conveniently.

[0047] On the one hand, the control assembly 4 further includes a detection module 44 and a one-way valve 45. The connection assembly 3 includes a tee 31. The tee 31 includes a third interface 311, a fourth interface 312 and a fifth interface 313. The third interface 311 is used to communicate with the adsorption cavity 11 of the suction cup 1. The fourth interface 312 is used to communicate with the detection module 44. The one-way valve 45 is disposed between the fifth interface 313 and the first interface 431 of the pump housing 43, so that the air at the fifth interface 313 flows unidirectionally to the pump housing 43. During use, after the control pump 42 starts to work, the detection module 44 starts to detect. When the preset value is detected, the suction cup 1 reaches the safe range, so the control pump 42 stops working. When the detection module 44 detects that the suction cup 1 is lower than the threshold value, the suction cup 1 starts to work again. In this embodiment, the preset value and the threshold value can be determined through multiple tests. The range between the threshold value and the preset value is the safe negative pressure range. More specifically, a limiting member 24 is provided inside the housing assembly 2. The limiting member has a limiting space 241, and the tee 31 is accommodated in the limiting space 241. Each interface of the tee 31 can be clamped in the limiting space 241. Specifically, the detection module 44 can be a pressure sensor.

[0048] In one embodiment, please refer to Figure 4, the connecting component 3 further includes a plurality of connecting pipes 32. For the plurality of connecting pipes 32, the fourth interface 312 is connected to the detection module 44 through one of the connecting pipes 32, the fifth interface 313 is connected to one end of the check valve 45 through one of the connecting pipes 32, and the other end of the check valve 45 is connected to the first interface 431 of the pump housing 43 through one of the connecting pipes 32. With such a setting, multiple structural elements can make full use of the spatial arrangement within the housing assembly 2, and then connect the various structural elements through the connecting pipes 32. It should be noted that the plurality of connecting pipes 32 can be flexible hoses to facilitate making full use of the space within the housing assembly 2.

[0049] More specifically, the housing assembly 2 includes a housing 22 and a connecting member 23. The connecting member 23 is detachably connected to the suction cup 1 to form a receiving cavity for receiving the housing 22. The side of the connecting member 23 facing away from the suction cup 1 has at least one connection interface 231 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.

[0050] Specifically, the connecting member 23 has four support arms 232. The four support arms 232 are connected to the suction cup 1 by screws, so that a receiving cavity 233 is formed between the connecting member 23 and the side of the suction cup 1 facing away from the adsorption cavity 11. The housing 22 can be installed in the receiving cavity 233, and structures such as electronic components can be installed in the housing 22, making the entire suction cup 1 modular in design, which is convenient for production and installation.

[0051] Specifically, the connection port is opened on the surface of the connecting member 23 facing away from the suction cup 1. Among them, the connection interface 231 includes at least one of a sprocket, a threaded interface, a NATO interface, a cold shoe interface, an Arca slide, and a Manfrotto slide; users can extend and 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 a connection structure.

[0052] In some embodiments, the connection interface 231 is movably connected to the side of the connecting member 23 facing away from the suction cup 1 through a rotating shaft, and the connection interface 231 includes one of a pipe clamp, a Michel interface, and a quick release mount. The quick release mount can be any quick release mount on the market, and will not be elaborated in this article.

[0053] In some embodiments, please refer to Figure 2-4 , the suction cup structure 10 includes a power supply 5 and a circuit board 6. The control component 4 and the power supply 5 are both arranged on the circuit board 6, and the power supply 5 is used to supply power to the control component 4 and the circuit board 6.
