For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0027] With reference to Figure 1 and Figure 2 , an adsorption device of an embodiment of the present application comprises: an adsorption body 100, a soft rubber adsorption accessory 200 is arranged on the adsorption body 100, the soft rubber adsorption accessory 200 has an adsorption surface 210 protruding from the adsorption body 100; the adsorption surface 210 comprises an annular plane 211 extending inward along the outer periphery of the soft rubber adsorption accessory 200 and a horn-shaped curved surface 212 arranged circumferentially around the geometric center of the soft rubber adsorption accessory 200 and connected with the inner periphery of the annular plane 211, the horn-shaped curved surface 212 can gradually approach the adsorption body 100 in the direction of the geometric center of the soft rubber adsorption accessory 200 from the inner periphery of the annular plane 211; an exhaust structure arranged on the adsorption surface 210 and / or the adsorption body 100, for exhausting the gas between the adsorption surface 210 and the surface to be mounted outward.

[0028] When the adsorption device with the above structure is mounted on the surface to be mounted, as the adsorption body 100 is pressed, the annular plane 211 first contacts the surface to be mounted, then the horn-shaped curved surface 212 gradually contacts the surface to be mounted from the inner periphery of the annular plane 211 to the geometric center of the soft rubber adsorption accessory 200, the gas between the adsorption surface 210 and the surface to be mounted is gradually exhausted outward through the exhaust structure, reducing the bubbles between the adsorption surface 210 and the surface to be mounted, thereby achieving the characteristics of stable adsorption and strong load bearing.

[0029] With reference to Figure 2In some embodiments of the present application, the adsorption body 100 is provided with a rectangular mounting groove 110, and the soft rubber adsorption member 200 is injection molded in the rectangular mounting groove 110. The exhaust structure includes an exhaust hole 310 penetrating the middle of the soft rubber adsorption member 200 and the rectangular mounting groove 110, and a first exhaust groove 320 provided on the horn-shaped curved surface 212. The first exhaust groove 320 extends along the length direction of the soft rubber adsorption member 200 to communicate with the exhaust hole 310. It can be understood that the rectangular mounting groove 110 provides an injection molding mounting space for the soft rubber adsorption member 200, which is beneficial to define the shape of the soft rubber adsorption member 200 and prevent displacement of the soft rubber adsorption member 200 relative to the adsorption body 100. The adsorption surface 210 as a whole protrudes from the rectangular mounting groove 110. When a user presses the soft rubber adsorption member 200 to fit the surface to be installed, the soft rubber adsorption member 200 can be elastically deformed to avoid direct collision between the adsorption body 100 and the surface to be installed. It should be noted that when the adsorption device is installed on the surface to be installed, as the adsorption body 100 is pressed, the annular flat surface 211 first contacts the surface to be installed, and then the horn-shaped curved surface 212 gradually contacts the surface to be installed along its outer edge towards the center position. The gas located between the adsorption surface 210 and the surface to be installed moves along the end of the first exhaust groove 320 towards the exhaust hole 310, thereby guiding other gases to the exhaust hole 310 for exhaust, thereby improving the bubble condition between the adsorption surface 210 and the surface to be installed. Moreover, the soft rubber adsorption member 200 is rectangular, and the long side dimension of the soft rubber adsorption member 200 is greater than the short side dimension, which is suitable for the case where the adsorption body 100 is long, thereby avoiding the use of multiple conventional circular adsorption members and making it more convenient to use.

[0030] Of course, in other embodiments, the contour shape of the soft rubber adsorption member 200 can also be hexagonal, octagonal or other polygonal shapes, or the contour shape of the soft rubber adsorption member 200 can be oval or the like. According to specific use needs, the contour shape of the soft rubber adsorption member 200 can be correspondingly configured.

[0031] Referring to Figure 2In some embodiments of the present application, the bottom wall of the rectangular mounting groove 110 is shaped with a sleeve 120 passing through the geometric center of the soft rubber suction accessory 200, the internal passage of the sleeve 120 constitutes the exhaust hole 310, the first exhaust groove 320 is located on the center line of the short side of the soft rubber suction accessory 200, and the first exhaust groove 320 extends from both ends of the length direction of the horn-shaped curved surface 212 to the inlet of the communication exhaust hole 310. In this embodiment, the suction body 100, the rectangular mounting groove 110 and the sleeve 120 are processed by one-piece injection molding, which is beneficial to simplify the production and processing flow of the suction device. Generally speaking, the suction body 100 is made of PP, PE or other materials with fixed shape after molding, and compared with the soft rubber suction accessory 200, the suction body 100 has no elasticity. When the soft rubber suction accessory 200 is injection molded in the rectangular mounting groove 110, the annular plane 211 is a rectangular ring, the projection of the horn-shaped curved surface 212 in the direction perpendicular to the bottom wall of the rectangular mounting groove 110 is also a rectangular ring, and the inner periphery of the horn-shaped curved surface 212 gradually approaches the bottom wall of the rectangular mounting groove 110 in the direction pointing to the exhaust hole 310.

[0032] Referring to Figure 1 Or Figure 3 In some embodiments of the present application, the horn-shaped curved surface 212 is provided with a plurality of second exhaust grooves 330 intersecting with the first exhaust groove 320, one end of the second exhaust groove 330 communicates with the first exhaust groove 320, and the other end of the second exhaust groove 330 extends to the outer peripheral edge of the horn-shaped curved surface 212. It should be noted that the main function of the first exhaust groove 320 is to guide the gas near the center line of the short side of the soft rubber suction accessory 200 to the exhaust hole 310, that is, the first exhaust groove 320 guides the gas to be discharged along the length direction of the soft rubber suction accessory 200, but it does not have a corresponding exhaust structure in the width direction of the soft rubber suction accessory 200, while the second exhaust groove 330 can guide the gas at the edge position of the long side of the soft rubber suction accessory 200 to the first exhaust groove 320 for convergence, so that the gas between each position of the horn-shaped curved surface 212 and the surface to be mounted can be easily guided to the exhaust hole 310 and then discharged.

[0033] Referring to Figure 1In some embodiments of the present application, a plurality of second exhaust grooves 330 are arranged at intervals along the extension direction of the first exhaust groove 320, and a bonding unit region is defined between two adjacent second exhaust grooves 330 and the first exhaust groove 320, and adjacent bonding unit regions are connected by the outer peripheral edge of the horn-shaped curved surface 212. It can be understood that the plurality of bonding unit regions formed at intervals by the above structure can help to improve the cooling and solidification rate of the soft rubber suction accessory 200, and can help to improve the stability of the shape of the suction surface 210 of the soft rubber suction accessory 200 after shrinkage. When the length of the rectangular soft rubber suction accessory 200 is much larger than the width of the soft rubber suction accessory 200, the middle position of the horn-shaped curved surface 212 is also not prone to a large degree of depression. Moreover, since adjacent bonding unit regions are connected by the outer peripheral edge of the horn-shaped curved surface 212, the entire soft rubber suction accessory 200 can be formed by one-time molding of the thermoplastic elastomer.

[0034] Referring to Figure 1 In some embodiments of the present application, a plurality of second exhaust grooves 330 are arranged at intervals along the extension direction of the first exhaust groove 320, and a bonding unit region is defined between two adjacent second exhaust grooves 330 and the first exhaust groove 320, and adjacent bonding unit regions are connected by the outer peripheral edge of the horn-shaped curved surface 212. It can be understood that the plurality of bonding unit regions formed at intervals by the above structure can help to improve the cooling and solidification rate of the soft rubber suction accessory 200, and can help to improve the stability of the shape of the suction surface 210 of the soft rubber suction accessory 200 after shrinkage. When the length of the rectangular soft rubber suction accessory 200 is much larger than the width of the soft rubber suction accessory 200, the middle position of the horn-shaped curved surface 212 is also not prone to a large degree of depression. Moreover, since adjacent bonding unit regions are connected by the outer peripheral edge of the horn-shaped curved surface 212, the entire soft rubber suction accessory 200 can be formed by one-time molding of the thermoplastic elastomer.

[0035] Referring to Figure 3 In some embodiments of the present application, the second exhaust groove 330 is inclined away from the exhaust hole 310 at the end away from the first exhaust groove 320, that is, the end of the second exhaust groove 330 away from the first exhaust groove 320 can extend to the corner of the rectangular soft rubber suction accessory 200, so as to ensure that the gas between the outer peripheral edge of the suction surface 210 and the surface to be mounted can be smoothly discharged after being discharged from the first exhaust groove 320.

[0036] Referring to Figure 4 In some embodiments of the present application, the exhaust structure includes a plurality of third exhaust grooves 340, one end of the third exhaust groove 340 is located on the horn-shaped curved surface 212, and the other end of the third exhaust groove 340 extends beyond the outer peripheral edge of the annular plane 211 to communicate with the external environment. It should be noted that in this embodiment, the exhaust hole 310 is not required. During the process of bonding the suction surface 210 to the surface to be mounted, the gas between the suction surface 210 and the surface to be mounted is discharged outward along the third exhaust groove 340 from the outer peripheral edge of the soft rubber suction accessory 200.

[0037] Referring to Figure 5 In some embodiments of the present application, the exhaust structure comprises an exhaust hole 310 penetrating through the soft rubber adsorption accessory 200 and the middle portion of the adsorption body 100, and a plurality of fourth exhaust grooves 350 radially distributed on the horn-shaped curved surface 212, one end of the fourth exhaust grooves 350 being communicated with the exhaust hole 310, and the other end of the fourth exhaust grooves 350 extending to the outer peripheral edge of the horn-shaped curved surface 212. The above exhaust structure utilizes the plurality of fourth exhaust grooves 350 radially distributed to quickly transport the gas at different positions between the horn-shaped curved surface 212 and the surface to be installed to the exhaust hole 310, reduces the air bubbles between the adsorption surface 210 and the surface to be installed, and improves the adsorption capacity of the adsorption device.

[0038] In addition, the conventional support or hanging basket and the like are connected in a split structure with the adsorption device, the distance between the support or hanging basket and the like and the surface to be installed is large, and the gravity moment of the articles acting on the adsorption device is large, thereby resulting in a weak load capacity of the adsorption device. Therefore, in some embodiments of the present application, the adsorption body 100 is provided with an embedded slot parallel to the length direction of the soft rubber adsorption accessory 200 on the back surface of the rectangular mounting groove 110, and correspondingly, the support device is provided with a plug block matched with the embedded slot. When the plug block is inserted into the embedded slot, the distance between the support device and the adsorption surface 210 of the soft rubber adsorption accessory 200 is short, that is, the gravity moment of the articles acting on the adsorption device is small, which is beneficial to enhancing the load capacity of the adsorption device.

[0039] The technical features of the above embodiments can be combined in any manner. In order to make the description concise, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not exist contradictions, they should be considered as the scope of the present application.

[0040] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the claims and their equivalents.
