Description

Technical Field

[0001] This utility model relates to the field of suction cup technology, and in particular to an intelligent suction cup structure. Background Technology

[0002] Vacuum suction cups, as a commonly used adsorption tool, work by utilizing the pressure difference between the inside and outside to generate adsorption force, thereby grasping and fixing objects. However, commonly available vacuum suction cups on the market generally suffer from problems such as being prone to falling off and insufficient adsorption durability, seriously affecting work efficiency and safety.

[0003] The core reason why vacuum suction cups fall off is vacuum leakage. However, conventional vacuum suction cups usually do not have the ability to actively replenish vacuum. Once a vacuum leakage occurs, the suction force will continue to decrease until it fails.

[0004] To address the issue of insufficient adhesion persistence in vacuum suction cups, some vacuum suction cups with automatic vacuum replenishment functions have emerged. These suction cups are typically designed with a vacuum pump and a sensor. When the vacuum level is detected to be below a set threshold, the vacuum pump automatically starts to replenish the vacuum within the suction cup, thereby maintaining the adhesion. However, existing automatic vacuum replenishment devices typically use a touch switch as the sensor triggering mechanism. Specifically, this type of touch switch includes a push-button switch that is triggered by the deformation of the suction cup. When the suction cup deforms due to vacuum leakage, the deformation compresses the push-button switch, thereby triggering the vacuum pump to start.

[0005] However, the aforementioned automatic vacuum replenishment device based on touch switches has the following drawbacks: it is not a purely mechanical switch, so its reliability needs to be improved; it has a large stroke and low sensitivity; it has a high cost; and it has a slow response speed.

[0006] Therefore, it is necessary to further improve and perfect the existing technology to overcome these shortcomings, and this utility model is made based on this situation. Utility Model Content

[0033] Figure 5 This is the second exploded view of this utility model. Detailed Implementation

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] like Figures 1 to 5 The illustrated smart suction cup structure includes a base 1, a cover 6 disposed above the base 1, and a flexible suction cup body 2 disposed below the base 1. The base 1 is made of a rigid material, such as ABS plastic, polycarbonate (PC), or metal. The shape of the base 1 can be designed according to actual needs, such as circular, square, or irregular shapes. In this embodiment, the base 1 is circular, which has better structural strength and stability.

[0036] The suction cup body 2 is composed of a soft rubber material, such as silicone rubber, natural rubber, or polyurethane elastomer. The hardness of the suction cup body 2 is preferably less than 60A to ensure good adhesion and sealing, and to adapt to objects of different materials and surface roughness. The shape of the suction cup body 2 can be designed according to actual needs, such as circular, elliptical, or rectangular. In this embodiment, the suction cup body 2 is circular, matching the shape of the base 1.

[0037] The bottom edge of the suction cup body 2 forms a sealed contact with the surface of the object being adsorbed, and the middle of its bottom surface is its inner cavity, which can form a closed vacuum cavity with the surface of the object being adsorbed.

[0038] The base 1 is provided with an electric vacuum device 3 that is connected to the inner cavity of the suction cup body 2 and can evacuate the inner cavity. The top of the suction cup body 2 is provided with a mechanical switch 4 that can be triggered by the up and down extension of the suction cup body 2. The electric vacuum device 3 and the mechanical switch 4 are electrically connected to a control circuit board 5.

[0039] The suction cup body 2 adheres to the wall surface by relying on the vacuum inside its cavity. When the vacuum level drops to a certain degree, the middle part of the suction cup body 2 deforms and triggers the mechanical switch 4 to close. This, in turn, causes the control circuit board 5 to activate the electric vacuum pump 3, automatically replenishing the vacuum and maintaining it for longer adhesion. After the suction cup body 2 replenishes the vacuum to a certain degree, it will retract, triggering the mechanical switch 4 to open again. The control circuit board 5 then controls the electric vacuum pump 3 to stop pumping air.

[0040] The intelligent suction cup structure of this invention can automatically replenish the vacuum level of the suction cup, maintaining a vacuum and extending its service life. Furthermore, the intelligent suction cup structure of this invention has the advantages of simple structure, ease of manufacture and maintenance, and low cost. More importantly, the mechanical switch 4 of this invention adopts a purely mechanical switch, with a short stroke and high sensitivity.

[0041] The mechanical switch 4 is the core component of this invention, used to detect changes in the vacuum level of the suction cup body 2 and trigger the electric vacuum pump 3 to perform a vacuum replenishment operation. Further, the mechanical switch 4 includes a pressing post 41 mounted on the base 1 and slidable vertically. The pressing post 41 is located between the cover 6 and the suction cup body 2, and a first elastic reset element 7 (such as a spring) is provided between the pressing post 41 and the cover 6 or suction cup body 2. The first elastic reset element 7 elastically presses the pressing post 41 downwards so that its lower end abuts against the suction cup body 2, while the upper end of the pressing post 41 abuts or elastically abuts against the cover 6. The sliding stroke of the pressing post 41 determines the sensitivity of the mechanical switch 4; a reasonable design of the pressing post 41's stroke can improve sensitivity. The first elastic reset element 7 is preferably an elastic element such as a spring or rubber pad. The elastic coefficient of the first elastic reset element 7 should be selected according to the material and size of the suction cup body 2 to ensure the sensitivity and reliability of the mechanical switch 4.

[0042] Furthermore, the mechanical switch 4 also includes a first contact 42 provided on the pressing column 41 and a second contact 43 provided on the base 1. The second contact 43 and the first contact 42 are positioned opposite each other and close or open as the pressing column 41 moves up and down.

[0043] It is worth noting that the first contact 42 is located on the side of the pressing post 41. That is, neither the first contact 42 nor the second contact 43 is at the top of the pressing post 41, but on the side of the pressing post 41, and is designed to be offset from the pressing post 41. The second contact 43 is not in direct contact with the pressing post 41, but is in contact with the first contact 42 on the side wall of the pressing post 41.

[0044] The stroke of the first elastic reset element 7 (such as a spring) is greater than the stroke of the first contact 42. The larger spring stroke effectively reduces the impact force on the contact, decreases wear caused by frequent operation, and thus extends the switch's service life. The spring stroke design also effectively absorbs vibrations from the suction cup, reducing the impact of noise and vibration on other internal components of the switch.

[0045] The first contact 42 and the second contact 43 are typically made of conductive material. Furthermore, both the first contact 42 and the second contact 43 are sheet-like metal contacts. When the pressing column 41 rises to a certain position, the first contact 42 and the second contact 43 come into contact, forming a closed circuit, triggering the control circuit board 5 to start the electric vacuum device 3.

[0046] The basic working principle of the intelligent suction cup structure of this utility model is as follows: When the user presses the cover 6, the air in the inner cavity of the suction cup body 2 is expelled, allowing the suction cup body 2 to initially adhere to the wall, forming a preliminary adsorption state. At this time, the electric vacuum device 3 is activated, starting to evacuate the inner cavity of the suction cup body 2. During the vacuuming process, the middle part of the suction cup body 2 gradually adheres to the wall due to the pressure of the vacuum adsorption, that is, it is concave. At this time, under the action of the elastic force of the first elastic reset member 7 (spring), the pressing column 41 also descends, and the second contact 43 on the pressing column 41 naturally moves downward as well. When the pressing column 41 descends to the point where the second contact 43 disengages from the first contact 42, the mechanical switch 4 is disconnected, transmitting a signal to the control circuit board 5.

[0047] After receiving a signal that the mechanical switch 4 has been disconnected, the control circuit board 5 will immediately control the electric vacuum device 3 to stop vacuuming, or the control circuit board 5 will control the electric vacuum device 3 to automatically stop vacuuming after a period of time. At this time, a stable vacuum state has been formed in the inner cavity of the suction cup body 2, the suction cup structure enters a standby state, and the suction force is maintained for a long time.

[0048] However, the inner cavity of the suction cup body 2 may leak air due to various reasons (such as insufficient airtightness or changes in the external environment). As the vacuum gradually decreases, the middle part of the suction cup body 2 gradually rebounds, that is, it gradually arches. This deformation gradually increases the upward thrust acting on the pressing post 41, the first elastic reset member 7 is gradually compressed, and the pressing post 41 gradually moves upward. When the upward movement of the pressing post 41 causes the second contact 43 to contact the first contact 42, the mechanical switch 4 closes, transmitting a closing signal to the control circuit board 5. After receiving the closing signal from the mechanical switch 4, the control circuit board 5 immediately activates the electric vacuum pump 3 to re-evacuate air from the inner cavity of the suction cup body 2 to replenish the vacuum, thereby restoring the adsorption performance.

[0049] Through the aforementioned automated air extraction and replenishment cycle, the intelligent suction cup structure of this invention can automatically monitor and maintain the vacuum level of the suction cup body 2, ensuring that the adsorption force is always at its optimal state. This intelligent working principle significantly improves the ease of use and adsorption stability of the suction cup structure.

[0050] Preferably, the first contact 42 is fixed to the pressing column 41 by means of screws or integral injection molding, and the second contact 43 is fixed to the base 1 by means of screws or integral injection molding. Both the first contact 42 and the second contact 43 are preferably made of strong metals such as stainless steel or copper (iron or aluminum will rust or wear and deform, and are not recommended). The thickness is preferably 0.3-2mm; too thin and it is easy to deform, too thick and the cost will be high.

[0051] Furthermore, the second contact 43 and the first contact 42 are arranged opposite each other in the vertical direction. Compared with left-right or front-back contact methods, vertical contact is more outstanding in terms of sensitivity and stability. This is because in actual use, the suction cup structure may be affected by external environmental interference, such as vibration and tilt. Vertical contact can reduce the impact of these interferences on contact closure, thereby ensuring that the switch triggering is more stable and reliable.

[0052] Furthermore, the vertical contact layout allows for more precise contact between contacts, reducing distance errors and improving contact closure accuracy. When the pressing post 41 moves vertically, the absolute path of contact is shorter, and contact fluctuation is reduced. This improves the switch's response speed and trigger sensitivity.

[0053] At the same time, this layout can effectively reduce the spherical effect between contact points, thereby ensuring that the control circuit board 5 can quickly and accurately receive the signals of contact closure and opening, and further optimize the automatic adjustment function of the suction cup structure.

[0054] It is worth mentioning that the vertical arrangement of the second contact 43 and the first contact 42 can better adapt to the deformation changes of the suction cup body 2 during use. When the suction cup body 2 undergoes slight deformation due to changes in vacuum, the vertical contact method can more sensitively capture this deformation and promptly trigger the switching action of the mechanical switch 4, thereby ensuring that the electric vacuum device 3 can start or stop working when most needed, effectively maintaining the suction effect of the suction cup.

[0055] In summary, the second contact 43 and the first contact 42 are arranged in a vertically opposite manner, which not only improves the sensitivity and stability of the mechanical switch, but also optimizes the overall performance of the suction cup structure, making the suction cup more efficient and reliable in the process of automatically adjusting the vacuum.

[0056] Furthermore, the electric vacuum device 3 includes an air pump 31. Preferably, the electric vacuum device 3 also includes a power supply component, which is preferably a rechargeable battery, to power the air pump 31 and the control circuit board 5.

[0057] The air pump 31 has an air extraction pipe 32 leading to the bottom surface of the suction cup body 2. The end of the air extraction pipe 32 is provided with a one-way air inlet valve 33. The bottom surface of the suction cup body 2 is provided with an air extraction hole 21 for accommodating the one-way air inlet valve 33.

[0058] The one-way air intake valve 33 is preferably a flexible one-way valve with a V-shaped nozzle. Its simple structure allows air to enter the air pump 31 in one direction. The V-shaped nozzle of the one-way air intake valve 33 optimizes the airflow path, reduces airflow resistance, and makes the pumping process more efficient. Simultaneously, the one-way valve design prevents backflow of gas during vacuum release, ensuring that the vacuum level of the suction cup body 2 can be quickly restored, thus improving the overall system's sealing and stability.

[0059] Furthermore, the base 1 is provided with a venting device 8 for releasing air from the inner cavity of the suction cup body 2. The venting device 8 is designed to allow the user to safely and quickly release the vacuum pressure inside the suction cup body 2 when the suction cup needs to be removed, thereby avoiding the problem of the suction cup being difficult to remove due to excessive suction force.

[0060] More specifically, the venting device 8 includes a valve seat 81 mounted on the base 1. The valve seat 81 contains a venting chamber 811, which serves as the airflow connection path between the inner cavity of the suction cup body 2 and the outside environment. One end of the venting chamber 811 is connected to the bottom surface of the suction cup body 2 via a venting hole 82, while the other end is connected to the external environment via an exhaust hole 83. To control the opening and closing of the exhaust hole 83, a valve core 84 is provided in the venting chamber 811 for opening and closing the exhaust hole 83. A manual venting button 85 is located at the top of the valve core 84. The user can easily drive the valve core 84 to move by pressing the manual venting button 85, thereby opening or closing the exhaust hole 83.

[0061] Furthermore, the valve core 84 is slidably connected within the venting chamber 811 (it can only move up and down, not rotate circumferentially). To further improve the sealing performance, a first sealing ring 86 is provided between the valve core 84 and the vent hole 83 to close the vent hole 83. This sealing ring, by engaging with the periphery of the vent hole 83 and the corresponding contact surface of the valve core 84, ensures that internal gas cannot flow back when the valve core 84 closes the vent hole 83, thereby maintaining the vacuum state inside the suction cup body 2. At the same time, to ensure that the valve core 84 can automatically return to the closed position, a second elastic reset member 87 is also provided in the venting chamber 811 to press the valve core 84 towards the vent hole 83. The second elastic reset member 87 is preferably a spring.

[0062] Preferably, the valve seat 81 is detachably connected to the seat body 1, preferably with a snap-fit ​​design. This connection method not only facilitates installation and maintenance but also allows for quick disassembly of the valve seat 81 for cleaning or replacement when needed. Furthermore, a second sealing ring 88 is provided between the valve seat 81 and the seat body 1 to ensure good airtightness at the connection point, preventing leakage at the connection from affecting the performance of the venting device 8.

[0063] In summary, the venting device 8 enables rapid and controllable release of the vacuum state within the suction cup body 2. Its advantages include ease of operation, reliable sealing, and compact structure. It can quickly release vacuum pressure when needed, thereby significantly reducing the difficulty of removing and unloading the suction cup.

[0064] The suction cup body 2 has an adsorption surface 22 that gradually rises from the outside to the inside around its bottom surface. During evacuation, the air inside the suction cup needs to flow from the periphery to the center. The gradual rise of the adsorption surface 22 effectively guides the air to move smoothly from the periphery to the center, thereby accelerating the formation of a vacuum and reducing evacuation time. Furthermore, the varying height of the adsorption surface 22 enhances the contact density between the suction cup and the wall, ensuring optimal contact and preventing a decrease in adsorption force due to uneven contact.

[0065] A raised suction cavity 23 is provided in the middle area of ​​the bottom surface of the suction cup body 2. The suction cavity 23 allows for centralized handling of the air extraction and venting functions, thereby simplifying the internal structure of the suction cup body 2. The aforementioned air extraction hole 21 and venting hole 82 are both located in the suction cavity 23.

[0066] Preferably, the center of the adsorption chamber 23 is provided with a downwardly protruding wall-abutting portion 24. The wall-abutting portion 24 can contact the wall surface, providing support for the pressing column 41, and can also prevent the aforementioned air extraction hole 21 and air vent 82 from being blocked during air extraction.

[0067] Preferably, the cover 6 is provided with a hook 9. Furthermore, the hook 9 is detachably connected to the cover 6. This design not only facilitates the installation and removal of the hook 9, but also allows users to flexibly choose whether to use the hook 9 according to their actual needs. The detachable connection method here is preferably a snap-fit, screw connection, or plug-in connection.

[0068] Furthermore, the control circuit board 5 is electrically connected to a buzzer 51 and an indicator light, which can intuitively display the working status of the suction cup structure or issue prompt signals. This design not only improves the intelligence level of the suction cup structure but also further enhances the user experience.
