Description

Technical Field

[0001] This invention relates to the field of camera equipment technology, specifically to an adsorption-type anti-tipping camera. Background Technology

[0002] A camera is an image acquisition device that converts real-world scenes into electronic signals through an optical imaging system. Its working principle is based on an optical lens group that focuses light onto the surface of a photosensitive element. The photosensitive element converts the light signal into an electrical charge signal through the photoelectric effect, which is then converted into digital image data by an analog-to-digital converter. Finally, an image processor performs optimization processing such as noise reduction and color correction. As the core carrier of modern visual perception, cameras are widely used in real-time situational awareness in security monitoring systems, pathological image acquisition in remote medical care, dynamic traffic flow analysis in intelligent transportation, automated quality inspection in industrial production, and human-computer interaction interfaces in the consumer electronics field, becoming the basic visual neural node for building a smart digital ecosystem.

[0003] Suction cup rotatable cameras, due to their compact size and ease of installation, are widely deployed in scenarios requiring dynamic viewing angle adjustment and non-destructive installation, such as vehicle-mounted mobile monitoring, glass curtain wall inspection, temporary security deployment, and mobile smart home devices. This is because they require dynamic environmental perception; for example, vehicle-mounted systems need to adjust the shooting angle in sync with vehicle steering, security systems need to periodically scan blind spots, and smart homes need to track people's movements in real time. This necessitates frequent rotation during operation. However, the mechanical movement of the rotating mechanism continuously damages the vacuum seal between the suction cup and the contact surface. Torque transmission causes micro-deformation at the edge of the suction cup, and repeated friction causes interface slippage, resulting in the formation and gradual expansion of micro-air gaps at the adsorption interface. Ultimately, this leads to a non-linear decay of the adsorption force. This inherent contradiction between motion function and structural stability makes the device prone to tipping over during rotation due to center of gravity shift and adsorption force imbalance. Tipping can easily damage the mechanical structure of the camera body, especially the displacement or breakage of precision optical components. At the same time, visual coverage interruption leads to the formation of blind spots, which can undermine the integrity of the security system and cause missed event recordings. To address this, we propose an adsorption-type anti-tipping camera. Summary of the Invention

[0004] One of the technical problems this application aims to solve is that the formation and gradual expansion of micro-gaps at the adsorption interface eventually leads to a non-linear decay of the adsorption force. This inherent contradiction between motion function and structural stability makes the device prone to tipping over during rotation due to the shift of the center of gravity and the imbalance of the adsorption force. Tipping over can easily cause damage to the mechanical structure of the camera body, especially the displacement or breakage of precision optical components. At the same time, the interruption of visual coverage leads to the formation of blind spots in monitoring, which will damage the integrity of the security system and result in missed event recordings.

[0005] To address the aforementioned technical problems, this application provides an adsorption-type anti-tipping camera, comprising a support base and a rotating base rotatably connected to the support base, with a camera body mounted on the rotating base.

[0009] In some embodiments, the pressure compensation unit includes a negative pressure component disposed in a fixed groove, which provides negative pressure for drawing air from inside the negative pressure suction cup. A compensation component is disposed on the support plate, which drives a push block to apply downward pressure to a push rod when the air pressure sensor detects an abnormal pressure inside the negative pressure suction cup, causing the loosened negative pressure suction cup to re-adhere to the adsorption surface and simultaneously connecting the negative pressure component to the negative pressure suction cup. A power component is disposed on the support plate, which provides power for the operation of the negative pressure component. A release component is disposed on the negative pressure component to control the start and stop of the power component.

[0010] In some embodiments, the negative pressure component includes a first fixed plate disposed on a support plate, a second fixed plate slidably disposed on the support plate, an expansion airbag disposed between the first fixed plate and the second fixed plate, a push spring disposed inside the expansion airbag, a positioning plate disposed on the support plate, a switching chamber disposed on the positioning plate, a first switching plate disposed inside the switching chamber, a second switching plate rotatably disposed inside the switching chamber and fitting against the first switching plate, both the first and second switching plates have mating grooves, a synchronization chamber disposed on the support plate opposite to the circular plate, the synchronization chamber being connected to multiple connecting pipes via flexible hoses, a guide pipe first and a guide pipe second disposed on both sides of the switching chamber on the first and second switching plates respectively, the first guide pipe being connected to the expansion airbag, and the second guide pipe being connected to the synchronization chamber, both the first and second guide pipes being flexible hoses.

[0011] In some embodiments, the compensation component includes a connecting shaft rotatably mounted on a support plate, the connecting shaft passing through the support plate, a synchronous pulley being provided on both the connecting shaft and the rotating shaft, a synchronous belt being sleeved on the synchronous pulley, a switching shaft being rotatably mounted on the switching chamber, and the switching shaft being connected to the second switching plate, and a switching gear meshing with each other being provided on both the switching shaft and the connecting shaft.

[0012] In some embodiments, the power component includes a mounting plate disposed on a support plate, a rotating plate rotatably disposed on the mounting plate, a connecting rod rotatably disposed on the rotating plate, a circulation chamber disposed on the side of a fixed plate away from the inflatable airbag, a piston plate slidably disposed within the circulation chamber, the piston plate rotatably connected to the connecting rod, a one-way exhaust valve disposed on the side wall of the circulation chamber, a one-way intake valve disposed on the fixed plate, and the circulation chamber communicating with the inflatable airbag through the one-way intake valve.

[0013] In some embodiments, the detachment component includes a power shaft mounted on a support base, the power shaft being connected to a rotating base, a docking rod being mounted on the rotating plate, the docking rod being a polygonal rod, a sleeve rod being slidably mounted on the power shaft, a locking groove being provided on the sleeve rod to slide with the docking rod, a lifting plate being mounted on the sleeve rod, a wedge-shaped lifting block being provided on the lifting plate, and an L-shaped plate being provided on the fixing plate to cooperate with the lifting block.

[0014] In some embodiments, the support plate is provided with an air storage chamber, the air storage chamber is provided with a compression spring, a piston plate slidably disposed in the air storage chamber and connected to the compression spring, the bottom end of the air storage chamber is connected to a one-way air outlet valve on the circulation chamber through a hose, a guide pipe is provided at the bottom of the air storage chamber, the guide pipe passes through the support plate, and an electrically controlled pressure valve is disposed in the guide pipe.

[0015] This invention has at least the following beneficial effects:

[0016] 1. Through real-time monitoring by the air pressure sensor and the linkage mechanism of the pressure compensation unit, when the suction cup becomes loose due to frequent camera rotation, downward pressure is automatically applied to make the suction cup reposition and adhere to the bearing surface, and at the same time, the internal air is sucked out to restore the negative pressure balance, thereby effectively improving the anti-interference ability of the equipment during dynamic use and avoiding adsorption failure caused by motion inertia; at the same time, the closed-loop adaptive adjustment mechanism can significantly reduce the frequency of manual intervention and enhance the long-term stability and reliability under complex working conditions.

[0017] 1. By using a circular array design of multiple small negative pressure suction cups, a redundant adsorption structure is formed, which significantly reduces the risk of overall detachment due to the failure of a single suction cup. The circumferentially distributed suction cups can work together to counteract the overturning torque generated in different directions when the camera rotates or shifts dynamically, ensuring that the device can maintain stable adsorption under complex motion conditions. The circular array layout makes the contact pressure distribution between each suction cup and the bearing surface more balanced, effectively avoiding the adsorption failure problem caused by local stress concentration of traditional single suction cups.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1: Please refer to Figures 1-10 This invention provides a technical solution: an adsorption-type anti-tipping camera, including a support base 1 and a rotating base 2 rotatably connected to the support base 1, and a camera device body 3 is provided on the rotating base 2. Multiple connecting pipes 4 are installed inside the support base 1, and each of the multiple connecting pipes 4 is equipped with a negative pressure suction cup 5. A pressure sensor 6 is installed inside each connecting pipe 4. A fixing unit 7 connected to the connecting pipes 4 is provided on the support base 1, and the fixing unit 7 fixes the multiple connecting pipes 4 and the negative pressure suction cups 5 connected to the connecting pipes 4 to the support base 1. A pressure compensation unit 10 connected to the connecting pipes 4 and the negative pressure suction cups 5 is provided inside the support base 1. When the pressure sensor 6 detects an abnormal pressure inside the negative pressure suction cup 5, the pressure compensation unit 10 is driven to apply downward pressure to the connecting pipes 4 and the negative pressure suction cup 5, causing the negative pressure suction cup 5 to re-adhere to the adsorption surface, while simultaneously sucking air from inside the negative pressure suction cup 5 to restore the negative pressure.

[0032] The fixing unit 7 includes a mounting component 8 disposed on the support base 1. Multiple connecting pipes 4 and negative pressure suction cups 5 are fixed to the support base 1 by the mounting component 8. The mounting component 8 is provided with a pressing component 9, which is used to press the negative pressure suction cups 5 to form negative pressure to fix the camera device body 3 when the support base 1 is placed.

[0033] Mounting component 8 includes a fixing groove 81 formed in the bearing seat 1. A circular plate 82 is provided in the fixing groove 81. The circular plate 82 is slidably connected to a plurality of connecting pipes 4, and the plurality of connecting pipes 4 are arranged in a circumferential array on the circular plate 82. A limiting plate 83 is provided at the end of the connecting pipe 4 away from the negative pressure suction cup 5.

[0034] The circular array design of multiple small negative pressure suction cups 5 forms a redundant adsorption structure, which significantly reduces the risk of overall detachment due to the failure of a single suction cup. At the same time, the circumferentially distributed negative pressure suction cups 5 can work together to counteract the overturning torque generated in different directions when the camera rotates or shifts dynamically, thereby ensuring that the device can maintain stable adsorption under complex motion conditions and maintain the stability of the camera during the recording process. In addition, the circular array layout makes the contact pressure distribution between each suction cup and the bearing surface more balanced, effectively avoiding the adsorption failure problem caused by local stress concentration of traditional single suction cups.

[0035] The pressing component 9 includes a support plate 91 disposed in a fixed groove 81, a push motor 92 disposed on the support plate 91, a rotating shaft 93 rotatably disposed on the circular plate 82, one end of the rotating shaft 93 being connected to the power output shaft of the push motor 92, and a rotating plate 94 disposed on the other end of the rotating shaft 93, and a plurality of push blocks 95 disposed on the rotating plate 94, wherein the plurality of push blocks 95 are wedge-shaped blocks, and a push rod 96 cooperating with the push blocks 95 is disposed on the plurality of connecting pipes 4.

[0036] When placing the camera equipment, first, the negative pressure suction cup 5 is placed against the contact surface. Then, the drive motor 92 is started, which drives the rotating shaft 93 to rotate synchronously. The rotation of the rotating shaft 93 drives the rotating plate 94 to rotate simultaneously, which in turn drives multiple push blocks 95 set on the rotating plate 94 to rotate around the rotating shaft 93. Because the push blocks 95 are wedge-shaped, when the push blocks 95 rotate, they will press down the push rod 96 and the connecting pipe 4 connected to the push rod 96. The connecting pipe 4 descends and then presses down on the negative pressure suction cup 5, thus fixing the camera equipment. Through the mechanical linkage between the drive motor 92 driving the rotating shaft 93 and the rotating plate 94, the wedge-shaped push blocks 95 convert the circumferential motion into the linear downward pressure of the push rod 96 during the rotation, realizing the synchronous pressing and fixing of multiple negative pressure suction cups 5, effectively improving installation efficiency and ensuring that each suction cup is subjected to uniform force. The integrated mechanical transmission design avoids the complexity of manual point-by-point pressing, and at the same time, the rigid linkage structure enhances the stability of pressure application, so that the suction cup and the bearing surface quickly form a uniform and reliable negative pressure adsorption state, significantly optimizing the convenience of equipment deployment and fixing strength.

[0037] The pressure compensation unit 10 includes a negative pressure component 11 disposed in a fixed groove 81. The negative pressure component 11 provides negative pressure for sucking air from inside the negative pressure suction cup 5. A compensation component 12 is disposed on the support plate 91. When the air pressure sensor 6 detects an abnormal pressure inside the negative pressure suction cup 5, the compensation component 12 drives the push block 95 to apply downward pressure to the push rod 96, causing the loosened negative pressure suction cup 5 to re-adhere to the adsorption surface, and simultaneously connecting the negative pressure component 11 to the negative pressure suction cup 5. A power component 13 is disposed on the support plate 91, which provides power for the operation of the negative pressure component 11. A release component 14 is disposed on the negative pressure component 11 to control the start and stop of the power component 13.

[0038] The negative pressure component 11 includes a first fixing plate 111 disposed on a support plate 91, a second fixing plate 113 slidably disposed on the support plate 91, an expansion airbag 112 disposed between the first fixing plate 111 and the second fixing plate 113, a push spring 114 disposed inside the expansion airbag 112, a positioning plate 115 disposed on the support plate 91, a switching chamber 116 disposed on the positioning plate 115, a first switching plate 117 disposed inside the switching chamber 116, and a second switching plate 118 rotatably disposed inside the switching chamber 116 and in contact with the first switching plate 117. Both the first plate 117 and the second switching plate 118 are provided with docking grooves 119. The bearing plate 91 is provided with a synchronization chamber 1110 on the side opposite to the circular plate 82. The synchronization chamber 1110 is connected to multiple connecting pipes 4 through flexible hoses. The switching chamber 116 is located on both sides of the first switching plate 117 and the second switching plate 118, and is provided with a first guide pipe 1111 and a second guide pipe 1112 respectively. The first guide pipe 1111 is connected to the inflatable airbag 112, and the second guide pipe 1112 is connected to the synchronization chamber 1110. Both the first guide pipe 1111 and the second guide pipe 1112 are flexible hoses.

[0039] When the camera rotates normally, the gas inside the inflatable airbag 112 is extracted, keeping the inflatable airbag 112 in a compressed state. Under the action of air pressure, the second fixing plate 113 moves towards the first fixing plate 111, and simultaneously squeezes the push spring 114 inside the inflatable airbag 112, causing the inflatable airbag 112 to compress. When the air pressure sensor 6 detects a pressure change inside the negative pressure suction cup 5, the rotating shaft 93 will work synchronously. When the rotating shaft 93 works, it drives the connecting shaft 121 to rotate synchronously through the synchronous pulley 122 and the synchronous belt 123. When the connecting shaft 121 rotates, it drives the switching gear 125 mounted on it to rotate. At the same time, the rotation of the switching gear 125 drives the rotation of the switching shaft 124, and the rotation of the switching shaft 124 drives the switching plate. When the second plate 118 rotates, the docking groove 119 on the second plate 118 coincides with the docking groove 119 on the first plate 117. At this time, the expansion airbag 112 is connected to the connecting pipe 4 and the negative pressure suction cup 5 through the guide pipe 1112 and the synchronization chamber 1110. At the same time as the connection is established, the negative pressure inside the expansion airbag 112 draws the gas in the negative pressure suction cup 5, so that the negative pressure suction cup 5 is fixed again on the adsorption surface. While the rotating shaft 93 rotates, it drives the rotating plate 94 and the pushing block 95 to rotate again, squeezing the loosened negative pressure suction cup 5 and making it re-adhere to the contact surface. This ensures that the negative pressure suction cup 5 is isolated from the external environment when the gas in the negative pressure suction cup 5 is drawn, thereby improving the stability during reinforcement.

[0040] When the inflatable airbag 112 is compressed, the push spring 114 is compressed synchronously and stores elastic potential energy, generating an outward restoring force that pushes the inflatable airbag 112 to expand. When the inflatable airbag 112 is connected to the loosened negative pressure suction cup 5, the two form a closed system. The push spring 114 releases energy, thereby increasing the volume of the inflatable airbag 112. According to the gas law (PV = nRT), if the temperature (T) is approximately constant and the total gas volume (n) remains unchanged, the increase in volume (V) will lead to a decrease in pressure (P). At this time, the pressure inside the inflatable airbag 112 is lower than that inside the negative pressure suction cup 5, and the gas passively flows from the negative pressure suction cup 5 to the inflatable airbag 112, creating a negative pressure inside the negative pressure suction cup 5. At the same time, the rotating plate 94 and the push block 95 squeeze the loosened negative pressure suction cup 5, causing it to re-adhere to the contact surface and restore the sealing state.

[0041] The inflatable airbag 112 is pre-compressed by the rotation of the camera during normal operation. When the camera rotation causes the negative pressure suction cup 5 to loosen, the air pressure sensor 6 triggers a signal, driving the motor 92 to rotate the rotating shaft 93. This rotation, via the synchronous pulley 122 and gear set, drives the switching shaft 124 to rotate, ensuring the alignment accuracy of the guide channel and the synchronicity of the sealing surface closure. This prevents pressure leakage due to timing deviations. Simultaneously, the inflatable airbag 112 forms a negative pressure reserve in the pre-compressed state. When the suction cup loosens, the internal negative pressure quickly draws out the residual pressure in the suction cup through the guide channel. At the same time, the mechanical pressure forces the edge of the suction cup to form a temporary sealing zone with the bearing surface, blocking the infiltration of external air and maximizing the efficiency of negative pressure reconstruction. During the suction cup resetting and bonding stage, the mechanical pressure is executed before the negative pressure suction action to ensure that the suction cup and the bearing surface form a preliminary physical seal, providing a sealed cavity condition for subsequent air pressure adjustment. The timing coupling of mechanical resetting and air pressure adjustment ensures that the suction cup is always in a sealed state during the reinforcement process, significantly improving the self-repair efficiency and system anti-interference ability under dynamic disturbances, and taking into account both response speed and reinforcement reliability.

[0042] The compensation component 12 includes a connecting shaft 121 rotatably mounted on the support plate 91, the connecting shaft 121 passing through the support plate 91, and a synchronous pulley 122 mounted on both the connecting shaft 121 and the rotating shaft 93, with a synchronous belt 123 sleeved on the synchronous pulley 122. A switching shaft 124 is rotatably mounted on the switching chamber 116 and is connected to the switching plate 118. Both the switching shaft 124 and the connecting shaft 121 are provided with meshing switching gears 125.

[0043] As the rotating shaft 93 rotates, it drives the rotating plate 94 and the pushing block 95 to rotate, squeezing the loosened and popped negative pressure suction cup 5, causing it to re-adhere to the contact surface. The downward pressing action forces the edge of the suction cup to adhere tightly to the bearing surface, forming a temporary physical sealing area, blocking the path of external air infiltration, creating a sealed environment for subsequent suction, and avoiding adsorption failure due to air leakage during the negative pressure establishment process.

[0044] The power component 13 includes a mounting plate 131 mounted on a support plate 91, a rotating plate 132 rotatably mounted on the mounting plate 131, a connecting rod 133 rotatably mounted on the rotating plate 132, a circulation chamber 134 disposed on the side of the fixed plate 111 away from the inflatable airbag 112, a piston plate 135 slidably disposed in the circulation chamber 134, the piston plate 135 rotatably connected to the connecting rod 133, a one-way exhaust valve 137 disposed on the side wall of the circulation chamber 134, and a one-way intake valve 136 disposed on the fixed plate 111, the circulation chamber 134 communicating with the inflatable airbag 112 through the one-way intake valve 136.

[0045] The detachment component 14 includes a power shaft 141 mounted on the support 1, the power shaft 141 being connected to the rotating seat 2, a docking rod 143 being mounted on the rotating plate 132, the docking rod 143 being a polygonal rod, a sleeve rod 142 being slidably mounted on the power shaft 141, the sleeve rod 142 having a locking groove 144 that slidably engages with the docking rod 143, a lifting plate 145 being mounted on the sleeve rod 142, a wedge-shaped lifting block 146 being mounted on the lifting plate 145, and an L-shaped plate 147 being mounted on the fixing plate that engages with the lifting block 146.

[0046] When the rotating base 2 drives the camera to rotate during operation, it drives the power shaft 141 connected to the rotating base 2 to rotate synchronously. Simultaneously, the rotation of the power shaft 141 drives the sleeve rod 142 to rotate, which in turn drives the rotating plate 132 to rotate synchronously through the locking groove 144 and the docking rod 143. The rotation of the rotating plate 132 also drives the connecting rod 133 to rotate, thereby pushing the piston plate 135 to slide within the circulation chamber 134, thus drawing gas from the inflatable airbag 112. During the continuous compression of the inflatable airbag 112, the fixing plate 113 gradually moves closer to... The L-shaped plate 147, which is connected to the fixed plate 113, is brought into contact with the lifting block 146 on the lifting plate 145. At this time, the lifting block 146 is pushed by the L-shaped plate 147 to disengage the locking groove 144 on the sleeve rod 142 from the docking rod 143, so that the piston plate 135 stops working, thereby avoiding excessive compression of the inflation airbag 112. When the fixed plate 113 is reset, the L-shaped plate 147 disengages from the lifting block 146. At this time, the sleeve rod 142 falls under the action of gravity and re-connects with the docking rod 143.

[0047] Through the mechanical linkage between the rotating seat 2 and the power shaft 141, the piston plate 135 is driven to draw gas from the inflatable airbag 112, thereby achieving continuous compression of the airbag and resetting of the fixing plate. When the compression is close to the limit, the contact between the L-shaped plate 147 and the lifting block 146 forces the locking groove 144 to disengage from the docking rod 143, automatically cutting off the power transmission of the piston plate 135. The compression stroke of the inflatable airbag 112 is limited by a purely mechanical means, effectively avoiding structural damage or sealing failure caused by over-compression. This design achieves autonomous start-stop control of pressure regulation with zero additional energy consumption, significantly improving the reliability and service life of the system in long-term dynamic working conditions.

[0048] Example 2: Please refer to Figure 11 The present invention provides a technical solution: an air storage chamber 15 is provided on a support plate 91, a compression spring 16 is provided inside the air storage chamber 15, a piston plate 17 is slidably provided inside the air storage chamber 15 and the piston plate 17 is connected to the compression spring 16, the bottom end of the air storage chamber 15 is connected to a one-way air outlet valve 137 on a circulation chamber 134 through a hose, a guide pipe 18 is provided at the bottom of the air storage chamber 15, the guide pipe 18 penetrates the support plate 91, and an electrically controlled pressure valve 19 is provided inside the guide pipe 18.

[0049] The gas extracted from the circulation chamber 134 is discharged into the gas storage chamber 15 through the one-way exhaust valve 137 and the hose. After the gas is discharged into the gas storage chamber 15, it squeezes the piston plate 17 and simultaneously compresses the compression spring 16. When the gas pressure in the gas storage chamber 15 reaches the preset threshold, the electronically controlled pressure valve 19 detects that the pressure has reached the standard and opens, so that the gas in the gas storage chamber 15 is sprayed into the fixed groove 81 through the guide pipe 18, thereby discharging the dust at the bottom of the support seat 1 and avoiding affecting the stability of the negative pressure suction cup 5.

[0050] The gas discharged from the circulation chamber 134 is introduced into the storage chamber 15 through the one-way exhaust valve 137. The air pressure pushes the piston plate 17 to compress the spring 16 to temporarily store energy. When the pressure in the storage chamber 15 reaches the preset threshold, the electronically controlled pressure valve 19 automatically opens, so that the high-pressure gas is sprayed out in a direction through the guide pipe 18, effectively removing the dust accumulated at the bottom of the support seat 1. This design forms a self-sustaining closed-loop cleaning system, which can maintain the cleanliness of the adsorption interface of the negative pressure suction cup 5 to ensure adsorption stability.

[0051] Example 2: Please refer to Figure 11The present invention provides a technical solution: an air storage chamber 15 is provided on a support plate 91, a compression spring 16 is provided inside the air storage chamber 15, a piston plate 17 is slidably provided inside the air storage chamber 15 and the piston plate 17 is connected to the compression spring 16, the bottom end of the air storage chamber 15 is connected to a one-way air outlet valve 137 on a circulation chamber 134 through a hose, a guide pipe 18 is provided at the bottom of the air storage chamber 15, the guide pipe 18 penetrates the support plate 91, and an electrically controlled pressure valve 19 is provided inside the guide pipe 18.

[0052] The gas extracted from the circulation chamber 134 is discharged into the gas storage chamber 15 through the one-way exhaust valve 137 and the hose. After the gas is discharged into the gas storage chamber 15, it squeezes the piston plate 17 and simultaneously compresses the compression spring 16. When the gas pressure in the gas storage chamber 15 reaches the preset threshold, the electronically controlled pressure valve 19 detects that the pressure has reached the standard and opens, so that the gas in the gas storage chamber 15 is sprayed into the fixed groove 81 through the guide pipe 18, thereby discharging the dust at the bottom of the support seat 1 and avoiding affecting the stability of the negative pressure suction cup 5.

[0053] The gas discharged from the circulation chamber 134 is introduced into the storage chamber 15 through the one-way exhaust valve 137. The air pressure pushes the piston plate 17 to compress the spring 16 to temporarily store energy. When the pressure in the storage chamber 15 reaches the preset threshold, the electronically controlled pressure valve 19 automatically opens, so that the high-pressure gas is sprayed out in a direction through the guide pipe 18, effectively removing the dust accumulated at the bottom of the support seat 1. This design maintains the cleanliness of the adsorption interface of the negative pressure suction cup 5 to ensure adsorption stability, and improves the sustainability of the system through energy recycling.
