[0002] Currently, in the field of photographic equipment, when shooting certain scenes for extended periods, requiring the camera equipment to be mounted in specific locations such as vehicles, walls, or other non-horizontal surfaces, the common method is to use vacuum suction cups to mount the equipment. Photographic equipment can utilize the suction cup's adsorption function; by integrating a suction cup mechanism, it can be installed and secured in its position more quickly and easily.

[0003] However, in traditional suction cups, the pneumatic control components that regulate suction are often arranged in a dispersed manner, occupying a large space and hindering the improvement of suction cup stability.

Detailed Implementation

[0034] 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.

[0035] 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.

[0036] 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).

[0037] The common disassembly method for vacuum suction cups in related technologies is for the user to manually pry up the suction cup body to create a gap between the suction cup body and the external structure to release pressure. Manual disassembly is laborious and inconvenient, and may damage the surface of the external structure, such as causing paint peeling on the vehicle body, which has certain negative effects.

[0038] To solve the above-mentioned technical problems, this embodiment provides a suction cup device 100, please refer to... Figures 1-9 The suction cup device 100 includes a suction cup body 10 and a pneumatic control component 20. One side of the suction cup body 10 has an adsorption cavity 11 for adsorption onto an external structure, and the side of the suction cup body 10 facing away from the adsorption cavity 11 has a mounting cavity 31. The pneumatic control component 20 is installed in the mounting cavity 31, and is separated from the adsorption cavity 11, effectively avoiding the influence of suction operations on the pneumatic control component 20.

[0039] The pneumatic control assembly 20 includes a negative pressure generator 21 and a control valve 22. The negative pressure generator 21 is connected to the adsorption chamber 11 through a pipeline to form a suction circuit. The negative pressure generator 21 is used to draw gas from the adsorption chamber 11, so that the suction cup body 10 can be adsorbed onto the external structure through the adsorption chamber 11. The control valve 22 is connected to the adsorption chamber 11 through a pipeline to form a pressure relief circuit. The control valve 22 can switch between an open state and an closed state. When the control valve 22 is in the open state, it releases the adsorption connection between the suction cup body 10 and the external structure.

[0040] According to the suction cup device 100 of the above embodiment, when it is needed to fix the suction cup body 10 to the external structure by means of air extraction, the conduction valve 22 is in the isolation state, and the gas in the adsorption chamber 11 is drawn by operating or controlling the negative pressure generator 21. If it is necessary to remove the suction cup body 10 from the external structure, it is only necessary to switch the conduction valve 22 to the conduction state interface. At this time, the gas can enter the adsorption chamber 11 through the conduction valve 22 and the pressure relief circuit, thereby relieving the negative pressure state of the adsorption chamber 11. On the one hand, by drawing air from the adsorption chamber 11 through the negative pressure generator 21 and the air extraction circuit, the suction cup device 100 can be fixed to the external structure, thereby realizing convenient fixation of the photographic equipment and meeting the fixation needs of photographic equipment in special scenarios. On the other hand, by changing the on / off state of the conduction valve 22, the suction cup device 100 can be switched between adsorption and disassembly, which greatly reduces the difficulty of disassembly and allows for faster and more convenient release of the adsorption connection between the suction cup device 100 and the external structure, thus improving the user experience. At the same time, this method will not damage the adsorption surface of the suction cup body 10, effectively protecting the structure of the suction cup device 100 and extending its service life.

[0041] It should be noted that the control valve 22 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. In some embodiments, please refer to... Figures 1-7 To enhance the user experience, the pneumatic control assembly 20 also includes an electrical control unit 50, which is located on the suction cup body 10. The control valve 22 is a solenoid valve, and the electrical control unit 50 is used to send control signals and receive feedback signals. The electrical control unit 50 is electrically connected to the control valve 22 to control the opening and closing of the control valve 22, eliminating the need for the user to manually open and close the control valve 22 and improving pressure relief efficiency.

[0042] In order to meet the usage requirements of photography equipment, in some embodiments, the conduction valve 22 is configured as a solenoid valve that closes when power is cut off. This configuration can effectively prevent the suction cup device 100 and the entire photography equipment from falling off due to accidental power failure during shooting.

[0043] In some embodiments, referring to the figures, the suction cup device 100 further includes a battery 51 and a pressure relief button 60. Both the control device 50 and the battery 51 are housed within the mounting cavity 31. The pressure relief button 60 is located on the cavity wall of the mounting cavity 31 and exposed outside the cavity for user pressing. The battery 51 is electrically connected to the control device 50, and the pressure relief button 60 is electrically connected to the control device 50. When the user presses the pressure relief button 60, a passage is formed between the battery 51 and the pressure relief module of the control device 50, thereby controlling the opening of the solenoid valve 22. 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 valve 22, 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 powered on, powered off, and 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.

[0044] In some embodiments, the electrical control 50 can be a circuit board 271 with a microcontroller integrated circuit. Different pins are connected to different circuit function modules to facilitate the microcontroller receiving signals and issuing corresponding instructions. Additionally, in some embodiments, the pressure relief control circuit can be switched on and off by introducing a PMOS switch. That is, the pressure relief button 60 is electrically connected to the circuit board 271, which has a PMOS switch circuit. The battery 51, the PMOS switch, and the conduction valve 22 form the aforementioned pressure relief control circuit. The circuit control principle is as follows: pressing the pressure relief button 60 energizes the PMOS switch, creating a path between the battery 51 and the venting module on the circuit board 271. This creates a path in the pressure relief control circuit, opening the conduction valve 22. In summary, when the pressure relief button 60 is pressed, the pressure relief path is open, and the conduction valve 22 opens. Under normal circumstances, when no path is formed, the conduction valve 22 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 button 60 can also create a passage between the battery 51 end and the venting module on the circuit board 271, allowing the venting valve 22 to work.

[0045] In some embodiments, please refer to Figures 1-7 In order to monitor the air pressure in the adsorption chamber 11, the air control assembly 20 also includes a negative pressure detection sensor 27 for measuring the air pressure in the adsorption chamber 11. The negative pressure detection sensor 27 is connected to the adsorption chamber 11. The negative pressure detection sensor 27 is a sensing and measuring device. By connecting to the corresponding electronic control module, when the air pressure reaches the safe negative pressure range, the chip on the electronic control unit 50 can control the negative pressure generator 21 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 electrical control 50, 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 1-9 The adsorption chamber 11 has a through-hole 12 on its wall. The pneumatic control assembly 20 also includes a negative pressure detection sensor 27, a circuit board 271, and a first multi-port connector 23. The negative pressure detection sensor 27 and the circuit board 271 are both located in the mounting cavity 31, with the negative pressure detection sensor 27 located on the circuit board 271. Multiple ports of the first multi-port connector 23 are connected to the through-hole 12, the negative pressure detection sensor 27, and the suction port of the negative pressure generator 21. The negative pressure generator 21 and the negative pressure detection sensor 27 are both connected to the adsorption chamber 11 through the first multi-port connector 23. In other words, the negative pressure detection sensor 27 is connected to one port of the first multi-port connector 23 through a connecting pipe to form a pressure measuring circuit connected to the adsorption chamber 11.

[0048] In some embodiments, please refer to Figure 1 , Figure 2 and Figure 10 As an arrangement of the circuit board 271 and the negative pressure detection sensor 27, the mounting cavity 31 is provided with a recess for fixing the circuit board 271. The circuit board 271 is arranged in the recess, and the negative pressure detection sensor 27 is disposed on the circuit board 271. Along the direction from the mounting cavity 31 to the adsorption cavity 11, the circuit board 271 is located between the pneumatic control component 20 and the adsorption cavity 11. The negative pressure detection sensor 27 is connected to one interface of the first multi-port connector 23 through a pipeline.

[0049] The first multi-port connector 23 can be a single component or assembled from two or more components. Furthermore, the first multi-port connector 23 can have two or more interfaces. When the number of interfaces of the first multi-port connector 23 is greater than two, 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.

[0050] In some embodiments, please refer to Figures 1-10One of the interfaces of the first multi-port connector 23 is connected to the control valve 22, so that the air intake ports of the control valve 22, the negative pressure detection sensor 27, and the negative pressure generator 21 are all connected to the air passage 12 through the first multi-port connector 23. Since only one air passage 12 is provided on the suction cup body 10, the adsorption chamber 11 is connected to the negative pressure generator 21 and the control valve 22 through the first multi-port connector 23. This not only reduces the difficulty of assembly, but also effectively improves the airtightness, thereby reducing the risk of air leakage. This effectively improves the adsorption stability of the suction cup device 100, which is beneficial to improving the user experience.

[0051] In addition, the pneumatic control component 20 is located in the mounting cavity 31. The pneumatic control component 20 and the adsorption cavity 11 are connected only through a single air passage 12. The negative pressure generator 21 and the conduction valve 22 are both connected to the air passage 12 and the adsorption cavity 11 through the first multi-port connector 23. This simplifies the arrangement and connection scheme of the pneumatic control component 20 and makes the arrangement of the pneumatic control component 20 more compact to a certain extent. This not only reduces the difficulty of assembly but also effectively improves airtightness to reduce the risk of air leakage, thereby effectively improving the adsorption stability of the suction cup device 100 and enhancing the user experience.

[0052] In some embodiments, please refer to Figures 1-7 The pneumatic control assembly 20 also includes a filter element 26, which is connected in series to the pressure relief circuit via a pipeline. Along the pressure relief circuit, the filter element 26 is positioned between the control valve 22 and the first multi-way connector 23, or the control valve 22 is positioned between the first multi-way connector 23 and the functional hole 32 of the filter element 26. The filter element 26 is used to filter impurities to prevent them from entering the first multi-way connector 23. The purpose of the filter element 26 is primarily to filter impurities such as sand and gravel from the external air entering the adsorption chamber 11 during the pressure relief process, preventing these impurities from reaching and remaining at the first multi-way connector 23. This reduces the impact of sand and gravel on the negative pressure generator 21, ensuring the normal operation of the suction cup device 100, reducing the failure rate, and effectively extending its service life.

[0053] It should be noted that in some embodiments, the mounting cavity 31 may not be a sealed chamber; it may be open to the atmosphere. The gas drawn in by the negative pressure generator 21 may be directly discharged into the mounting cavity 31 and then into the atmosphere. In some embodiments, a desiccant capable of absorbing moisture may be placed in the mounting cavity 31, and the impact of moisture in the gas on the pneumatic control component 20 may be reduced by periodically replacing the desiccant. Similarly, in some embodiments, the suction port of the pressure relief circuit may be located inside the mounting cavity 31; in other embodiments, the suction port may be located outside the mounting cavity 31, for example, extending outside the mounting cavity 31 via a pipeline. The approximate flow direction of the gas in the pressure relief circuit is: atmosphere – pressure relief circuit suction port – conduction valve 22 – adsorption cavity 11.

[0054] In some embodiments, the exhaust port of the negative pressure generator 21 and the intake port of the pressure relief circuit may not extend out of the mounting cavity 31 through a pipe. Alternatively, in some embodiments, one of the exhaust port of the negative pressure generator 21 and the intake port of the pressure relief circuit extends out of the mounting cavity 31 through a pipe, while the other is located directly inside the mounting cavity 31.

[0055] In some embodiments, please refer to Figures 1-7 The pneumatic control component 20 is installed in the mounting cavity 31. The cavity wall of the mounting cavity 31 has a functional hole 32 that communicates with the external space. The functional hole 32 connects the mounting cavity 31 and the external space. At least one of the exhaust port of the negative pressure generator 21 and the conduction valve 22 is connected to the atmosphere through a pipe installed in the functional hole 32 or through a pipe that passes through the functional hole 32 and extends out of the mounting cavity 31.

[0056] This application does not limit the number of functional holes 32. In some embodiments, there may be two or more functional holes 32. In some embodiments, the exhaust port of the negative pressure generator 21 and the intake port of the pressure relief circuit are both connected to the atmosphere through a pipe installed in the functional hole 32 or a pipe passing through the functional hole 32 and extending out of the mounting cavity 31, and the exhaust port of the negative pressure generator 21 and the intake port of the pressure relief circuit utilize different functional holes 32. In other embodiments, the exhaust port of the negative pressure generator 21 and the intake port of the pressure relief circuit may also share a single functional hole 32, so that the exhaust of the suction and the external connection of the pressure relief share a single hole to simplify the structure.

[0057] In some embodiments, please refer to Figures 1-7The negative pressure generator 21 has an exhaust port located within the mounting cavity 31. The pneumatic control assembly 20 also includes a second multi-port connector 24, a first pipe 251, a second pipe 252, and a third pipe 253. Multiple ports of the second multi-port connector 24 are respectively connected to one end of the first pipe 251, one end of the second pipe 252, and one end of the third pipe 253. The other end of the first pipe 251 is connected to the exhaust port of the negative pressure generator 21. The other end of the second pipe 252 is connected to the control valve 22. The other end of the third pipe 253 is installed in the functional hole 32 or passes through the functional hole 32 and extends out of the mounting cavity 31. The first pipe 251, the second pipe 252, and the third pipe 253 are connecting pipes. The gas drawn by the negative pressure generator 21 is discharged from the mounting cavity 31 into the atmosphere through the third pipe 253, effectively preventing moisture in the gas drawn by the negative pressure generator 21 from remaining in the mounting cavity 31. Simultaneously, during the pressure relief operation, the control valve 22 opens, allowing external air to enter the mounting cavity 31 through the third pipe 253, the second multi-way connector 24, the control valve 22, and the first multi-way connector 23, thus enabling the suction cup body 10 to detach from the external structure. Furthermore, the external connection for air extraction and pressure relief shares a single functional hole 32, effectively simplifying the structure of the suction cup device 100 and improving assembly efficiency. In some embodiments, the third pipe 253 and the pressure relief hole 32 can also be sealed together.

[0058] To ensure the stability of the suction cup device 100, in some embodiments, a negative pressure generator 21 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.

[0059] To ensure the stability of the suction cup device 100 in use, please refer to the following embodiments: Figures 1-9 The pneumatic control component 20 may also include a one-way valve 29. The suction port of the negative pressure generator 21 is connected to the interface of the first multi-port connector 23 through the one-way valve 29, and then connected to the air passage 12 and the adsorption chamber 11. Under the action of the one-way valve 29, the gas in the adsorption chamber 11 can only flow unidirectionally to the suction port of the negative pressure generator 21. When the negative pressure generator 21 stops working, the one-way valve 29 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.

[0060] In some embodiments, please refer to Figures 1-9 The first multi-port connector 23 is a four-way connector. The negative pressure detection sensor 27 is located in the mounting cavity 31. The negative pressure detection sensor 27, the air inlet of the one-way valve 29, the conduction valve 22, and the air passage hole 12 of the suction cup body 10 are respectively connected to the four interfaces of the first multi-port connector 23.

[0061] This invention does not limit the structure and selection of the negative pressure generating element 21, and those skilled in the art can adopt any feasible solution. For example, in some embodiments, in order to improve the adsorption effect of the suction cup device 100, the negative pressure generating element 21 can be an electronically controlled device. The suction cup device 100 is also equipped with an air extraction switch 52 electrically connected to the negative pressure generating element 21. When the user needs the suction cup device 100 to automatically adsorb and fix, the air extraction switch 52 is pressed, and the motor drive circuit is controlled by the microcontroller, thereby turning the motor of the negative pressure generating element 21 on or off to extract the air in the adsorption chamber 11.

[0062] Considering the high dependence of electric suction cups on power, they will stop working in the event of a power outage, and a failure in any part of the electronic control system will affect the normal operation of the suction cup, making repair and replacement inconvenient. For other embodiments, please refer to... Figure 8 and Figure 9 The negative pressure generating component 21 may include a manual vacuum pump 211 and a vacuum pump 212. The gas control component 20 also includes a third multi-port connector 28. The suction port of the manual vacuum pump 211 is connected to the first interface of the third multi-port connector 28, the suction port of the vacuum pump 212 is connected to the second interface of the third multi-port connector 28, and the one-way valve 29 is connected to the third interface of the third multi-port connector 28. The user can choose to manually operate the manual vacuum pump 211 or the electrically controlled vacuum pump 212 to evacuate the gas in the adsorption chamber 11, thus obtaining a manual and automatic dual-purpose suction cup device 100, which can provide the user with two usage options. When the user wants to install and fix the device more quickly and effortlessly, the vacuum pump 212 can be used for automatic suction.

The connecting seat 40 is detachably connected to the suction cup body 10, and the housing 30 is located between the connecting seat 40 and the suction cup body 10. On the one hand, the existence of the clearance space ensures that the assembly of the connecting seat 40, the housing 30 and the suction cup body 10 will not interfere with each other. On the other hand, it can effectively reduce the overall volume occupied by the suction cup device 100, making the overall layout of the suction cup device 100 more compact.

[0069] In some embodiments, please refer to Figures 1-4 The connecting seat 40 includes two side plates 42 and a base plate 43.

The housing 30 is positioned and engaged with the suction cup body 10. The connecting seat 40 and the suction cup body 10 are detachably connected and fixed. The housing 30 is positioned and fixed between the connecting seat 40 and the suction cup body 10.

[0070] In some embodiments, please refer to Figures 1-4 The side panel 42 may be provided with a window for exposing part of the structure of the housing 30 or part of the structure of the electrical control 50, so as not to interfere with the installation and use of the housing 30 and the electrical control 50.

[0071] In some embodiments, in order to enable the suction cup device 100 to be applied to the field of photography and realize the function of adsorbing and fixing the photographic equipment to the installation position, the expansion interface can be a commonly used interface in the field of photography, including but not limited to threaded interface, toothed plate interface, tube clamp, cold shoe interface and NATO interface.

[0072] In some embodiments, please refer to Figures 1-9 The suction cup device 100 also includes a battery 51, a vacuum switch 52, and an electronic control module.

Furthermore, other structures of the suction cup device 100 not described herein can be found in the prior art and will not be described in detail here.

[0073] Based on the same inventive concept, this embodiment also provides a photography kit, including a photography device and the suction cup device 100 in the above embodiment. The photography device is detachably connected to the suction cup device 100. The photography device can be fixed to an external structure by the suction cup device 100, so that the photography device can integrate the function of adsorption and fixation. The photography device can be quickly installed and adsorbed on external installation positions such as vehicles or walls, thereby meeting the installation requirements of the photography device and ensuring the installation stability of the photography device.

[0074] In summary, the suction cup device 100 and the photography kit provided by this utility model have at least the following beneficial effects:

[0075] According to the suction cup device 100 described above, by using the negative pressure generator 21 and the air extraction circuit to draw air from the suction chamber 11, the suction cup device 100 can be fixed to the external structure, thereby achieving convenient fixation of the photographic equipment and meeting the fixation needs of photographic equipment in special scenarios. At the same time, by changing the on / off state of the control valve 22, the suction and disassembly of the suction cup device 100 can be switched, greatly reducing the difficulty of disassembly and enabling faster and more convenient release of the suction connection between the suction cup device 100 and the external structure.

[0076] According to the suction cup device 100 described above, since only one air passage hole 12 is provided on the suction cup body 10, the adsorption chamber 11 is connected to the negative pressure generating element 21 and the conduction valve 22 through the first multi-port connector 23. This not only reduces the difficulty of assembly, but also effectively improves the airtightness to reduce the risk of air leakage, thereby effectively improving the adsorption stability of the suction cup device 100 and improving the user experience.

[0077] According to the above-mentioned photography kit, since the photography kit has the suction cup device 100, the photography equipment can be fixed to the external structure through the suction cup device 100, so that the photography equipment can integrate the function of suction fixation. The photography equipment can be quickly installed and attached to external installation positions such as vehicles or walls, thereby meeting the installation requirements of the photography equipment and ensuring the installation stability of the photography equipment.
