Detailed Implementation

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0035] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0036] The applicant discovered that there are currently two main types of vacuum suction cups: manually operated ones, which are physically demanding, and electrically operated ones. To improve the suction effect, suction cup devices in related technologies often employ an electrically operated suction system. This system uses a microcontroller to control the motor drive circuit, which in turn turns the vacuum pump motor on or off, allowing the vacuum pump to remove air from the suction cup. However, electrically operated suction cups are highly dependent on power; they stop working when the power is off. Furthermore, a malfunction in any part of the electrical control system can affect the normal operation of the suction cup, making repair and replacement inconvenient.

[0037] To address the aforementioned technical problems, this utility model provides a suction cup device and a photography kit, reducing the dependence of the suction cup device on usage conditions, improving its practicality, and providing users with multiple usage modes, allowing users to choose the appropriate usage solution according to their own needs and habits. Please refer to... Figures 1-9 The suction cup device 100 includes a suction cup body 10 and a gas control component 20. The suction cup body 10 has an adsorption cavity 11 for adsorbing onto an external structure. The gas control component 20 is disposed on the suction cup body 10 and is used to draw gas from the adsorption cavity 11. The gas control component 20 includes a manual air extraction component 21 and an electric air extraction component 22. The air extraction port of the manual air extraction component 21 is connected to the adsorption cavity 11, and the air extraction port of the electric air extraction component 22 is also connected to the adsorption cavity 11. The user can selectively draw gas from the adsorption cavity 11 using either the manual air extraction component 21 or the electric air extraction component 22, so that the suction cup body 10 can be adsorbed onto the external structure.

[0038] According to the suction cup device 100 of this embodiment, by simultaneously providing a manual suction component 21 and an electric suction component 22, a dual-purpose suction cup device 100 integrating manual and automatic operation is obtained. This provides users with two usage options. When users want to install and fix the device more quickly and effortlessly, they can use the electric suction component 22 for automatic suction. When users want to manually suction, or when the electric suction function cannot be used in the current situation, users can manually operate the manual suction component 21 to suction the gas in the suction chamber 11. This suction cup device 100 can effectively reduce the dependence of the suction cup device 100 on the usage conditions, improve the practicality of the suction cup device 100, and provide users with multiple usage modes, allowing users to choose the corresponding usage option according to their own needs and habits, thereby improving the user experience.

[0039] This utility model does not limit the specific selection of the manual suction component 21 and the electric suction component 22. As a feasible embodiment, the manual suction component 21 can be a suction cylinder and the electric suction component 22 can be a vacuum pump. The manual suction component 21 and the electric suction component 22 discharge the gas in the suction chamber 11 into the atmosphere.

[0040] To ensure the stability of the suction cup device 100, in some embodiments, a manual suction component 21 and / or an electric suction component 22 that integrates one-way air extraction and prevents gas from flowing back into the adsorption chamber 11 can be selected to effectively prevent gas from flowing back into the adsorption chamber 11 and causing adsorption failure, which can greatly improve the adsorption stability of the suction cup body 10.

[0041] To ensure the stability of the suction cup device 100 in use, please refer to the following embodiments: Figures 5-8 The pneumatic control component 20 may also include a one-way valve 23. The suction port of the manual suction component 21 is connected to the adsorption chamber 11 through the one-way valve 23, so that the gas in the adsorption chamber 11 flows to the suction port of the manual suction component 21. The suction port of the electric suction component 22 is connected to the adsorption chamber 11 through the one-way valve 23, so that the gas in the adsorption chamber 11 flows to the suction port of the electric suction component 22. Under the action of the one-way valve 23, when both the manual suction component 21 and the electric suction component 22 stop working, the one-way valve 23 can ensure that the gas pressure in the adsorption chamber 11 is still within the safe negative pressure range, thereby effectively preventing the gas from flowing back into the adsorption chamber 11 and causing adsorption failure, which can greatly improve the adsorption stability of the suction cup body 10.

[0042] This utility model does not specifically limit the number and arrangement of the one-way valves 23. For example, in some embodiments, there can be two one-way valves 23, which are respectively located between the manual suction component 21 and the adsorption chamber 11 and between the electric suction component 22 and the adsorption chamber 11.

[0043] In some embodiments, please refer to Figures 5-8To simplify the structure of the suction cup device 100, the pneumatic control assembly 20 also includes a first multi-port connector 241 and multiple connecting pipes. The one-way valve 23 is connected to the suction chamber 11 via one of the connecting pipes. One port of the first multi-port connector 241 is connected to the outlet of the one-way valve 23 via one of the connecting pipes. The suction port of the manual suction component 21 is connected to one port of the first multi-port connector 241, and the suction port of the electric suction component 22 is connected to the other port of the first multi-port connector 241. In other words, the three ports of the first multi-port connector 241 are respectively connected to the outlet of the one-way valve 23, the suction port of the manual suction component 21, and the suction port of the electric suction component 22. Connecting the manual suction component 21 and the electric suction component 22 in parallel to the outlet of the one-way valve 23 via the first multi-port connector 241 effectively reduces the number of connecting pipes and the wiring difficulty, thus helping to control the overall space occupied by the suction cup device 100.

[0044] It should be noted that the first multi-port connector 241 can be a single component or an assembly of two or more components. Furthermore, the first multi-port connector 241 can have three or more interfaces. When the number of interfaces of the first multi-port connector 241 is greater than three, the other interfaces can be connected to other components as needed to achieve other functions, or a blocking scheme can be adopted to ensure the flow of gas.

[0045] In some embodiments, please refer to Figures 5-9 In order to monitor the air pressure in the adsorption chamber 11, the air control assembly 20 also includes a detection element 28 for measuring the air pressure in the adsorption chamber 11. The detection element 28 is set in the electrical control unit 50 and is connected to the adsorption chamber 11. The detection element 28 is a sensing and measuring device. It is connected to the corresponding electrical control module of the electrical control unit 50 so that when the air pressure reaches the safe negative pressure range, the chip on the electrical control module can control the electric air extraction component 22 to stop working.

[0046] In some embodiments, in order to make it easier for users to know the negative pressure value in the suction chamber 11, the suction cup device 100 may also include a display screen, which is electrically connected to the circuit module, and the air pressure of the suction cup body 10 can be displayed in real time through the display screen.

[0047] To further simplify the structure of the suction cup device 100 and improve its operational stability, please refer to... Figures 1-10The adsorption chamber 11 has a through-hole 12 on its wall. The pneumatic control assembly 20 also includes a second multi-port connector 242, multiple connecting pipes, and a sensor 28 for measuring the air pressure inside the adsorption chamber 11. The second multi-port connector 242 is located on the suction cup body 10. The sensor 28 is connected to one port of the second multi-port connector 242 through a connecting pipe to form a pressure measurement circuit. The multiple ports of the second multi-port connector 242 are connected to the through-hole 12, the sensor 28, and the air inlet of the one-way valve 23, so that the air inlet of the sensor 28, the manual air extraction device 21, and the electric air extraction device 22 are all connected to the through-hole 12. Since the suction cup body 10 is connected to the pneumatic control assembly 20 through only one through-hole 12, the assembly difficulty is reduced, and the airtightness is effectively improved to reduce the risk of air leakage.

[0048] In order to facilitate the separation of the suction cup device 100 from the external structure, in some embodiments, a pressure relief component may be provided on the suction cup body 10. For example, a protrusion for easy disassembly of the suction cup body 10 may be fixedly provided on the outer surface of the suction cup body 10. By controlling the protrusion, one side of the suction cup body 10 can be lifted up to facilitate the disassembly of the suction cup body 10.

[0049] To facilitate the separation of the suction cup device 100 from the external structure, in some embodiments, please refer to... Figure 5 , Figure 6 ,and Figure 9 The pneumatic control assembly 20 may further include a pressure relief valve 25. The pressure relief valve 25 is located on the suction cup body 10 and communicates with the adsorption chamber 11. The pressure relief valve 25 can switch between an open state and an closed state. In the open state, the pressure relief valve 25 connects the adsorption chamber 11 and the external space, so that the suction cup body 10 can be released from adsorption with the external structure. It should be noted that the pressure relief valve 25 can be a manually operated ordinary valve or a solenoid valve. Those skilled in the art can select and arrange it according to their needs, and this application does not impose any limitations.

[0050] In some embodiments, please refer to Figure 10The suction cup device 100 also includes a battery 51 and a pressure relief switch 60. The pneumatic control assembly 20 also includes an electrical control 50. The solenoid valve 25 is a solenoid valve. The pressure relief switch 60 is electrically connected to the solenoid valve. Both the electrical control 50 and the battery 51 are placed inside the mounting cavity 31. The pressure relief switch 60 is exposed for the user to press. The battery 51 is electrically connected to the electrical control 50, and the pressure relief switch 60 is electrically connected to the electrical control 50. When the user presses the pressure relief switch 60, a passage is formed between the battery 51 and the pressure relief module of the electrical control 50, thereby controlling the opening of the solenoid valve 25. The suction cup device 100 has a built-in battery 51, and by forming a pressure relief control circuit between the battery 51 and the solenoid valve 25, the pressure relief function of the suction cup device 100 can be performed in various operating conditions, including when the suction cup device 100 is on, off, or in standby mode. Meanwhile, the depressurization and suction cup evacuation operations do not interfere with each other, and after the evacuation is completed, the suction cup device 100 does not need to be kept powered on to remain stably attached to the external structure. Users can adjust the suction cup device 100 to a suitable working mode according to their needs.

[0051] Specifically, in some embodiments, the electrical control 50 can be a circuit board with a microcontroller integrated circuit. Different pins are connected to different circuit function modules to facilitate the microcontroller receiving signals and issuing corresponding instructions. In other embodiments, the pressure relief control circuit can be switched on and off by introducing a PMOS switch. That is, the pressure relief switch 60 is electrically connected to the circuit board, which has a PMOS switch circuit. The battery 51, the PMOS switch, and the conduction valve 25 form the aforementioned pressure relief control circuit. The circuit control principle in this case is as follows: pressing the pressure relief switch 60 energizes the PMOS switch, creating a path between the battery 51 and the venting module on the circuit board. This creates a path in the pressure relief control circuit, and the conduction valve 25 opens. In summary, in this paper, after pressing the pressure relief switch 60, the pressure relief path is opened, and the conduction valve 25 opens. Under normal circumstances where no path is formed, the conduction valve 25 is closed. With the built-in battery 51, when the suction cup device 100 is in standby mode or after pressing the power off button to enter standby mode, pressing the pressure relief switch 60 can also create a passage between the battery 51 and the venting module on the circuit board, allowing the venting valve 25 to work.

[0052] In some embodiments, please refer to Figures 3-9To further simplify the structure of the suction cup device 100 and improve its operational stability, one interface of the second multi-port connector 242 is connected to the control valve 25, so that the control valve 25, the detection element 28, the air intake of the manual air extraction element 21, and the air intake of the electric air extraction element 22 are all connected to the air passage 12 through the second multi-port connector 242. In other words, multiple interfaces of the second multi-port connector 242 are connected to the air intake of the detection element 28, the air passage 12, the control valve 25, and the one-way valve 23. Since the suction cup body 10 is connected to the pneumatic control component 20 through only one air passage 12, the assembly difficulty is reduced, and the airtightness is effectively improved to reduce the risk of air leakage.

[0053] In some embodiments, please refer to Figures 5-9 The second multi-port connector 242 is a four-way connector. The detection element 28 is located inside the housing 30. The detection element 28, the air inlet of the one-way valve 23, the conduction valve 25, and the air passage 12 of the suction cup body 10 are respectively connected to the four interfaces of the second multi-port connector 242.

[0054] In some embodiments, please refer to Figure 9 The pneumatic control assembly 20 may also include a filter element 27, which is connected to the control valve 25 and is located between the control valve 25 and the adsorption chamber 11 or between the control valve 25 and the external space. In other words, the filter element 27 is used to filter impurities to effectively prevent impurities from entering the second multi-port connector 242 and the adsorption chamber 11. The purpose of the filter element 27 is mainly to filter impurities such as sand and gravel from the external air that enter the adsorption chamber 11 during the depressurization process, so that the impurities cannot reach and remain at the second multi-port connector 242, thereby reducing the impact of sand and gravel on the electric suction device 22, ensuring the normal operation of the suction device 100, reducing the failure rate, and effectively extending the service life.

[0055] In some embodiments, please refer to Figures 1-9 The suction cup device 100 may also include a housing 30, with the pneumatic control component 20 disposed inside the housing 30. The housing 30 is provided with a pressure relief hole 32 that communicates with the outside. The control valve 25 is connected to the pressure relief hole 32 through a connecting pipe, or the control valve 25 is connected to the atmosphere through a connecting pipe extending out of the pressure relief hole 32, thereby connecting the control valve 25 with the atmospheric environment.

[0056] In some embodiments, please refer to Figures 1-9The pneumatic control assembly 20 also includes a third multi-port connector 243, a first pipe 261, a second pipe 262, and a third pipe 263. Multiple ports of the third multi-port connector 243 are respectively connected to one end of the first pipe 261, one end of the second pipe 262, and one end of the third pipe 263. The other end of the first pipe 261 is connected to the exhaust port of the electric suction device 22. The other end of the second pipe 262 is connected to the control valve 25. The other end of the third pipe 263 is installed in or extends out of the pressure relief hole 32. The first pipe 261, the second pipe 262, and the third pipe 263 are connecting pipes. The third pipe 263 is sealed to the pressure relief hole 32. Gas drawn by the electric suction device 22 is discharged outside the housing 30 through the third pipe 263 to effectively prevent moisture in the gas from entering the housing 30. When the pressure relief action is performed, the control valve 25 opens, allowing external air to enter the receiving cavity through the third pipe 263, the third multi-way connector 243, the control valve 25, and the second multi-way connector 242, thus enabling the suction cup body 10 to detach from the external structure. On one hand, the exhaust port of the electric suction component 22 is discharged outside the housing 30 through the first pipe 261, the third multi-way connector 243, and the third pipe 263, effectively preventing moisture and protecting the internal pneumatic control components 20 of the housing 30. On the other hand, this design allows the housing 30 to simultaneously perform both suction and pressure relief functions with only one pressure relief hole 32, simplifying the structure of the housing 30.

[0057] To further ensure the normal operation of the pneumatic control component 20 and reduce the risk of damage to the electrical components inside the housing 30 caused by moisture in the external air, appropriate sealing measures can be adopted. For example, in some embodiments, the housing 30 may include an upper shell 34 and a lower shell 35, which are detachably connected and enclose a cavity. The pneumatic control component 20 and other required components are placed in the cavity. A sealing ring 33 is provided between the upper shell 34 and the lower shell 35. If some components of the pneumatic control component 20 need to extend out of the housing 30, a sealing ring 33 is also provided in the corresponding part to achieve the sealing of the cavity and reduce the impact of external humid air on the components inside the cavity.

[0058] It should be noted that, in some other embodiments, the gas drawn in by the electric suction unit 22 can also be discharged into the housing 30 and then released into the atmosphere through the pressure relief hole 32. In some embodiments, it is also possible to provide some desiccant that can absorb moisture in the housing 30, and reduce the impact of moisture in the gas on the gas control component 20 by replacing the desiccant periodically.

[0059] In some embodiments, please refer to Figures 1-9The suction cup device 100 also includes a housing 30, in which the pneumatic control component 20 is encapsulated. The housing 30 has a functional hole communicating with the outside. The exhaust port of the electric suction component 22 is connected to the functional hole via a connecting pipe, or the exhaust port of the electric suction component 22 is connected to the atmosphere via a connecting pipe extending out of the functional hole, so that the gas sucked by the electric suction component 22 in the adsorption chamber 11 is directly discharged outside the housing 30. This effectively prevents moisture or other impurities in the gas from entering the housing 30, achieving the functions of moisture protection and protection of the pneumatic control component 20. In some embodiments, the functional hole and the pressure relief valve 25 can coexist. To balance the moisture protection of the suction cup device 100 and the pressure relief of the pressure relief valve 25, in one feasible implementation, the housing 30 can simultaneously have a functional hole and a pressure relief hole 32, which are independent of each other, so that the exhaust action of the electric suction component 22 and the pressure relief action of the pressure relief valve 25 are performed independently. In another feasible implementation, such as... Figures 1-9 As shown, the pressure relief hole 32 can also be directly configured as a functional hole, so that the exhaust and external communication of the pressure relief are connected by the same hole, thus simplifying the structure of the housing 30.

[0060] In some embodiments, please refer to Figures 1-9 The manual suction device 21 includes an exhaust section 212 located outside the housing 30 and a piston section 211 for manual suction by the user. The housing 30 is also equipped with a suction switch 52 electrically connected to the electric suction device 22. Both the piston section 211 and the exhaust section 212 of the manual suction device 21 extend outside the housing 30. Manually operating the piston section 211 to reciprocate can suck in the air in the adsorption chamber 11 and finally discharge it from the suction cup device 100 through the exhaust section 212. When the user needs the suction cup device 100 to automatically adsorb and fix, the user presses the suction switch 52. Under control, the electric suction device 22 automatically operates to suck out the air in the adsorption chamber 11 and finally discharge it through the pressure relief hole 32 of the housing 30.
