Detailed Implementation

[0032] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figures 1 to 3 One embodiment of this utility model provides an electric suction cup, including: a housing 10, an annular light guide structure 20, an indicator light assembly 30, an electric vacuum assembly 40, and a vacuum suction cup 50.

[0033] The housing 10 is provided with a connecting part 11, and an inner cavity 12 is formed inside the housing 10. The inner cavity 12 has an annular light outlet 121, which is arranged around the connecting part 11. The connecting part 11 is used to connect with the bracket structure of the photographic equipment or other suitable structure. In this embodiment, the connecting part 11 is a threaded hole.

[0034] The annular light guide structure 20 is located at the annular light outlet 121.

[0035] The indicator light assembly 30 is disposed in the inner cavity 12 and emits light toward the annular light guide structure 20.

[0036] The vacuum suction cup 50 is located on the side of the housing 10 away from the connecting part 11, and the vacuum suction cup 50 is provided with an air inlet 51.

[0037] The electric vacuum assembly 40 is disposed in the inner cavity 12 and connected to the air inlet 51. The electric vacuum assembly 40 is electrically connected to the indicator light assembly 30.

[0038] The working principle of the electric suction cup according to one embodiment of the present invention is explained below:

[0039] The vacuum suction cup 50 is attached to the fixed position to be adsorbed, and a negative pressure cavity is formed between the vacuum suction cup 50 and the fixed position. The electric vacuum assembly 40 extracts the gas in the negative pressure cavity through the air inlet 51, thereby creating a negative pressure in the negative pressure cavity, and thus enabling the vacuum suction cup 50 to be adsorbed at the fixed position.

[0040] The indicator light emitted by the indicator light assembly 30 can be emitted from the annular light outlet 121 under the guidance of the annular light guide structure 20. The indicator light emitted by the indicator light assembly 30 can indicate different operating states of the electric vacuum assembly 40 through different colors, brightnesses, or flicker frequencies. In this embodiment, the indicator light assembly 30 indicates different operating states of the electric vacuum assembly 40 by emitting indicator light of different colors.

[0041] Please see Figure 4 The specific structure of the annular light guide structure 20 can be designed according to actual needs. For example, in some optional embodiments, the annular light guide structure 20 includes a lampshade 21 and a light guide ring 22. The lampshade 21 is disposed on the outside of the housing 10 and blocks the annular light outlet 121. The light guide ring 22 is disposed inside the annular light outlet 121. The indicator light emitted by the indicator light assembly 30 can pass through the light guide ring 22 and the lampshade 21 in sequence before being emitted outside the housing 10. The lampshade 21 can be a diffuser plate, which is beneficial to improving the uniformity of light emission.

[0042] In some optional embodiments, the housing 10 includes an outer shell 13 and a supporting frame 14. The outer shell 13 is arranged around the supporting frame 14, and the outer shell 13 and the supporting frame 14 form an inner cavity 12. A connecting portion 11 is disposed on the supporting frame 14. An annular light guide structure 20 is arranged around the supporting frame 14, and a sealing ring 15 is provided between the annular light guide structure 20 and the supporting frame 14, and between the annular light guide structure 20 and the outer shell 13. A vacuum suction cup 50 is connected to the supporting frame 14. The outer shell 13 and the supporting frame 14 cooperate to clamp the annular light guide structure 20, and the sealing ring 15 between the annular light guide structure 20 and the supporting frame 14 is pressed onto the annular light guide structure 20 by the supporting frame 14. The sealing ring 15 between the annular light guide structure 20 and the outer shell 13 is pressed onto the annular light guide structure 20 by the outer shell 13, which effectively improves the waterproofness, preventing liquid from entering the inner cavity 12 from the gaps between the supporting frame 14 and the annular light guide structure 20 and between the annular light guide structure 20 and the outer shell 13. The structural design of the supporting frame 14 and the outer shell 13 effectively improves the structural strength of the shell 10.

[0043] In some alternative embodiments, both the support frame 14 and the outer shell 13 are provided with limiting step portions 16, and the sealing ring 15 is correspondingly disposed on the limiting step portion 16. The position of the sealing ring 15 is restricted by the limiting step portion 16, thereby improving the positional stability of the sealing ring 15.

[0044] In some alternative embodiments, the support frame 14 is provided with a plurality of support legs 141, which are arranged around the vacuum suction cup 50 and connected to the vacuum suction cup 50, thereby facilitating the connection between the vacuum suction cup 50 and the support legs 141.

[0045] Please see Figure 5 and Figure 6 Since the vacuum suction cup 50 is typically made of an elastic material, the connection between the vacuum suction cup 50 and the support leg 141 is relatively unstable. Therefore, in some alternative embodiments, an inner frame 52 is provided inside the vacuum suction cup 50, with a portion of the inner frame 52 extending to the outside of the vacuum suction cup 50. The support leg 141 and the portion of the inner frame 52 extending to the outside of the vacuum suction cup 50 are also included. The inner frame 52 helps to improve the strength of the vacuum suction cup 50 and facilitates a fixed connection with the support leg 141, effectively improving structural strength.

[0046] Please see Figure 7The specific structure of the electric vacuum assembly 40 can be designed according to actual needs. For example, in some optional embodiments, the electric vacuum assembly 40 includes a vacuum pump 41, a battery 42, a pressure sensor 43, and a control board 44. The vacuum pump 41 and the pressure sensor 43 are both connected to the air inlet 51, and the indicator light assembly 30, the vacuum pump 41, the pressure sensor 43, and the battery 42 are all electrically connected to the control board 44. When the vacuum suction cup 50 needs to be fixed in position, the vacuum pump 41 evacuates air from the negative pressure chamber through the air inlet 51. The battery 42 supplies power to the indicator light assembly 30, the vacuum pump 41, the pressure sensor 43, and other structures. The pressure sensor 43 detects the air pressure in the negative pressure chamber. After the air pressure in the negative pressure chamber reaches a predetermined pressure, the control board 44 sends a control signal to the vacuum pump 41, and the vacuum pump 41 stops running.

[0047] When the vacuum suction cup 50 needs to be released from its fixed position, the negative pressure chamber needs to be refilled with gas. This can be achieved by opening the vacuum suction cup 50 or by other means. In this embodiment, the housing 10 is provided with an air outlet 17 and a sealing ring 18. The sealing ring 18 and the air outlet 17 are detachably connected. When the vacuum suction cup 50 needs to be released from its fixed position, the sealing ring 18 is removed from the air outlet 17, so that the gas passes through the air outlet 17 and enters the negative pressure chamber, thereby restoring the air pressure in the negative pressure chamber to atmospheric pressure. This makes the operation more convenient for the user.

[0048] In some optional embodiments, the electric vacuum assembly 40 further includes a three-way valve 45, a first two-way valve 46, and a second two-way valve 47. The three-way valve 45, the first two-way valve 46, and the second two-way valve 47 are all electrically connected to the control board 44. The air inlet 51 is connected to the three-way valve 45. The three-way valve 45 is connected to the first two-way valve 46, the second two-way valve 47, and the air pressure sensor 43, respectively. The first two-way valve 46 is connected to the vacuum pump 41. An air outlet 17 is provided on the housing 10, and the second two-way valve 47 is connected to the air outlet 17.

[0049] When the vacuum suction cup 50 needs to be adsorbed into a fixed position, the first double-way valve 46 opens and the second double-way valve 47 closes. The vacuum pump 41 starts and evacuates the negative pressure chamber. The gas in the negative pressure chamber passes through the three-way valve 45 and the first double-way valve 46 in sequence and then reaches the vacuum pump 41. The indicator light assembly 30 emits light of the first color.

[0050] After the vacuum suction cup 50 completes adsorption, the first double-way valve 46 closes, the second double-way valve 47 closes, the vacuum pump 41 shuts down, and the indicator light assembly 30 emits a second color light.

[0051] When vacuum adsorption requires release from a fixed position, the first double-way valve 46 closes, the vacuum pump 41 shuts off, and the second double-way valve 47 opens. This allows gas outside the housing 10 to sequentially pass through the vent 17, the second double-way valve 47, the three-way valve 45, and the vent 17 before entering the negative pressure chamber. At this time, the indicator light assembly 30 emits a third-color light. In this embodiment, the second double-way valve 47 is connected to the vent 17 through the inner cavity 12, allowing gas outside the housing 10 to enter the inner cavity 12 and then pass through the second double-way valve 47, the three-way valve 45, and the vent 17.

[0052] The first, second, and third colors are different colors, for example, green, red, and yellow respectively.

[0053] In some alternative embodiments, a charging interface 48 is also provided on one side of the housing 10. The charging interface 48 is electrically connected to the battery 42, and the sealing ring 18 can also be detached to seal the charging interface 48.

[0054] In some alternative implementations, a power button is provided on the control panel 44, and a portion of the sealing ring 18 extends from the vent 17 into the inner cavity 12 and then abuts against the power button. The user can press the power button by pressing the sealing ring 18.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
