[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0028] A preferred embodiment of the present invention provides a self-adhesive suction cup for use on a mobile phone screen, such as... Figures 1-7 As shown, it includes a plate-shaped suction cup body 11 and a first suction assembly 12; in this embodiment, the first suction assembly 12 is a gas manifold as in the prior art; the suction cup body 11 has an inwardly recessed groove 111 in the middle; a guide plate 13 is provided in the groove 111; an adsorption groove 14 is formed between the outer edge of the guide plate 13 and the inner sidewall of the groove 111; a plurality of protrusions 131 protruding from the upper surface of the suction cup body 11 are provided on the upper surface of the guide plate 13 along its length direction; the upper surfaces of all protrusions 131 are located on the same plane; a gap is formed between two adjacent protrusions 131. A first air passage 132 is connected to the adsorption groove 14; the suction cup body 11 is also provided with at least two second air passages 112, both of which are connected to the groove 111; optionally, the two second air passages are located on both sides of the groove 111; the second air passages 112 are connected to the first suction assembly 12 through the first air pipe 15; when the first suction assembly 12 sucks air into the groove 111, the adsorption groove 14 generates a negative pressure and the first air passage 132 generates a positive pressure. The positive pressure on the guide plate 13 is less than the negative pressure on the adsorption groove 14 to avoid deformation of the middle part of the product due to being tightly attached to the suction cup body 11. In this embodiment, the product can be a mobile phone screen, especially suitable for ultra-thin mobile phone screens.

[0029] The self-suction chuck applied to the mobile phone screen is designed ingeniously, the flow guide plate is arranged in the groove of the chuck body, the airflow in the groove can be guided to flow in the preset direction, uniform airflow distribution is formed in the suction groove of the chuck, according to Bernoulli's principle, when the first air suction assembly sucks air, negative pressure is generated in the suction groove and positive pressure is generated in the first air channel, the positive pressure on the flow guide plate is smaller than the negative pressure in the suction groove to avoid deformation of the middle part of the product due to close contact with the chuck body; the upper surface of the convex plate is higher than the upper surface of the chuck body, and the negative pressure in the suction groove can make the chuck body suction the product in the air, which can effectively prevent the product from being dirty and wrinkled.

[0030] Further, the second air suction assembly 16 is further included; in the embodiment, the second air suction assembly can adopt the vacuum generator in the prior art, or other structures capable of realizing air suction in the prior art. The third air channel 113 is arranged on both sides of the groove 111 in the chuck body 11; the upper surface of the chuck body 11 is provided with a plurality of vacuum suction holes 114 connected with the two third air channels 113; the third air channel 113 is connected with the second air suction assembly 16 through the second air pipe 17. After the chuck contacts the product, the two side vacuum suction holes are also generated by the second air suction assembly 16, that is, the vacuum generator generates vacuum to further suction the edge of the product, at this time, the flow guide plate is disconnected to supply air, which can make the product suction more closely and prevent the product from falling due to high-speed movement in the moving process.

[0031] Further, the cross section of the suction groove 14 is reduced from top to bottom. Since the width of the suction groove 14 gradually decreases, the airflow speed will increase. According to Bernoulli's principle, in the area where the flow rate increases, the static pressure of the airflow will decrease to generate negative pressure; the generation of negative pressure makes the chuck body more closely suction the product.

[0032] Further, the diameter of the middle part of the first air channel 132 is larger than the diameter of both ends; similarly, according to Bernoulli's principle, the width of the middle part of the first air channel 132 increases, the airflow speed decreases, the airflow speed slows down, the static pressure in this area is relatively high, thereby generating positive pressure in the middle of the chuck, which slows down the suction force of the middle part of the chuck body on the middle part of the product, avoiding deformation of the middle part of the product due to close contact with the chuck body.

[0033] Further, the suction cup body 11 is provided with a clamping groove 115 at the bottom of the groove 111, which is matched with and clamped with the guide plate 13; the guide plate 13 can be detachably connected with the suction cup body 11, which is convenient to disassemble and assemble, or convenient to replace the new guide plate; the design of the clamping groove 115 can also ensure that the guide plate 13 is stably fixed at the correct position of the suction cup body, preventing it from shifting during use; in another embodiment, the guide plate can also be integrally connected with the suction cup body 11, all of which are within the protection scope of the present application. The bottom of the suction cup body 11 is provided with a plurality of first through holes 116 which are communicated with the clamping groove 115 along the length direction of the groove 111; which helps to form a more uniform pressure distribution at the bottom of the suction cup, improving the adhesion of the suction cup body to the surface of the adsorbed product.

[0034] Alternatively, the two second air channels 112 are located on the lower side of the groove 111; the guide plate 13 is provided with a second through hole 133 which is communicated with any second air channel 112. During use of the suction cup, the second through hole 133 can help to remove the gas that may accumulate in the adsorption groove 14 and the first air channel 132, maintain the negative pressure state, and ensure the continuous and effective adsorption of the suction cup.

[0035] Further, the second through hole 133 is located below the first air channel 132; the first air channel 132 is communicated with the second air channel 112 through the second through hole 133. It can more effectively guide the airflow, and can help to guide the positive pressure gas in the first air channel 132 into the second air channel 112, which can enhance the negative pressure effect of the adsorption groove 14, so that the suction cup can more firmly adsorb the mobile phone screen.

[0036] Further, the gas outlet end of the second air channel 112 is connected with the first air pipe 15 through the first connecting head 18; the gas outlet end of the third air channel 113 is connected with the second air pipe 17 through the second connecting head 19; which helps to improve the sealing performance of the connection part, reduces gas leakage, and thus maintains the adsorption force of the suction cup; the first connecting head 18 and the second connecting head 19 are located at the same end of the suction cup body 11; which can facilitate the user to operate and control, and the structure is more compact and the space is used reasonably.

[0037] Further, the third air channel 113 is located above the second air channel 112; the second connecting head 19 and the first connecting head 18 are arranged in an upper and lower staggered manner; the suction cup body 11 is provided with a step 117 for placing the second connecting head 19; which makes it more convenient for the user to connect or disconnect the second connecting head, because the step can play a positioning role, and the step 117 can play a role in protecting the second connecting head 19 from being damaged during placement or use. The first connecting head and the second connecting head do not interfere with each other during assembly, avoiding collision or friction between the connecting heads during operation or use.

[0038] Further, the suction cup body 11 is provided with a plurality of third through holes 118 in the outer periphery of the groove 111; the upper surface of the suction cup body 11 is also provided with a transition groove 119 communicating the third through hole 118 and the groove. It helps to improve the smoothness of air flow, so that the suction cup is more smooth in the process of adsorption and release; the bottom of the suction cup body 11 is also provided with a positioning groove 1110 in the outer periphery of the groove 111, so as to facilitate the cooperation and connection with the external components; the plurality of third through holes 118 are located in the positioning groove 1110. The third through hole 118 is located in the outer periphery of the groove 111, which can help the air flow in and out more evenly, so as to form more stable adsorption force around the suction cup body; the circumferential arrangement of the plurality of third through holes 118 can ensure that the pressure is evenly distributed when the suction cup is adsorbed, reduce the local overpressure or underpressure, and protect the mobile phone screen or other adsorption surface.
