[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the following will be described clearly and completely in combination with the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are partial embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0028] A self-priming suction cup for a mobile phone screen according to a preferred embodiment of the present invention is as follows: Figure 1-7 As shown, it includes a plate-shaped suction cup body 11 and a first suction component 12; in this embodiment, the first suction component 12 is a gas bus in the prior art; a groove 111 is provided in the middle of the suction cup body 11; 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 side wall of the groove 111; a plurality of bosses 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 the bosses 131 are located in the same plane; and a groove 14 is formed between two adjacent bosses 131. The first air channel 132 is connected to the adsorption groove 14; at least two second air channels 112 are also provided in the suction cup body 11, both of which are connected to the groove 111; optionally, the two second air channels are respectively located on both sides of the groove 111; the second air channel 112 is connected to the first air suction component 12 through the first air pipe 15; when the first air suction component 12 sucks air from the groove 111, the adsorption groove 14 generates negative pressure and the first air channel 132 generates positive pressure, and the positive pressure on the guide plate 13 is less than the negative pressure of the adsorption groove 14 to avoid deformation of the middle part of the product due to close contact with 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-priming suction cup applied to the mobile phone screen is cleverly designed. By arranging a guide plate in the groove of the suction cup body, the airflow in the groove can be guided to flow in a preset direction, ensuring uniform airflow distribution in the adsorption groove of the suction cup. Through the multiple bosses in the middle of the suction cup and the first air channel between two adjacent bosses, according to the Bernoulli principle, when the first suction component sucks air into the groove, the adsorption groove generates negative pressure and positive pressure is generated in the first air channel. The positive pressure on the guide plate is less than the negative pressure of the adsorption groove to avoid deformation of the middle part of the product due to close contact with the suction cup body; the upper surface of the boss is higher than the upper surface of the suction cup body, and the negative pressure generated in the adsorption groove can enable the suction cup body to adsorb the product in the air, which can effectively prevent the product from being dirty and wrinkled.

[0030] Furthermore, it also includes a second suction component 16; in this embodiment, the second suction component can adopt a vacuum generator in the prior art, or can adopt other structures in the prior art that can achieve suction. The suction cup body 11 is provided with third air channels 113 on both sides of the groove 111; the upper surface of the suction cup body 11 is provided with a plurality of vacuum adsorption holes 114 respectively connected to the two third air channels 113; the third air channel 113 is connected to the second suction component 16 through the second air pipe 17. After the suction cup contacts the product, the vacuum adsorption holes on both sides are vacuumed by the second suction component 16, that is, the vacuum generator, and then adsorb the edge of the product. At this time, disconnecting the air supply of the guide plate can make the product adsorbed more tightly and prevent the product from falling due to high-speed movement during movement.

[0031] Furthermore, the cross section of the adsorption groove 14 is tapered from top to bottom. As the width of the adsorption groove 14 gradually decreases, the airflow velocity increases. According to the Bernoulli principle, in the area where the flow velocity increases, the static pressure of the airflow decreases and thus generates negative pressure; the generation of negative pressure enables the suction cup body to more tightly adsorb the product.

[0032] Furthermore, the diameter of the middle part of the first air channel 132 is larger than the diameter of both ends thereof; similarly, according to Bernoulli's principle, the width of the middle part of the first air channel 132 increases, and the air flow velocity decreases here, which slows down the static pressure in this area, thereby generating a positive pressure in the middle of the suction cup, reducing the adsorption force of the middle part of the suction cup body on the middle part of the product, and avoiding deformation of the middle part of the product due to close contact with the suction cup body.

[0033] Furthermore, the suction cup body 11 is provided with a card slot 115 adapted to and engaged with the guide plate 13 at the bottom of the groove 111; the guide plate 13 can be detachably connected to the suction cup body 11, which is convenient for disassembly and assembly, or for replacing a new guide plate; the design of the card slot 115 can also ensure that the guide plate 13 is firmly fixed in the correct position of the suction cup body to prevent it from shifting during use; in another embodiment, the guide plate can also be integrally connected to the suction cup body 11, all of which are within the scope of protection of the present invention. The bottom of the suction cup body 11 is provided with a plurality of first through holes 116 connected to the card slot 115 in sequence along the length direction of the groove 111; this helps to form a more uniform pressure distribution at the bottom of the suction cup and improve the fit between the suction cup body and the surface of the adsorbed product.

[0034] Optionally, both second air passages 112 are located at the lower side of the groove 111; the guide plate 13 is provided with a second through hole 133 connected to any second air passage 112. When the suction cup is in use, the second through hole 133 can help remove the gas that may accumulate in the adsorption groove 14 and the first air passage 132, maintain a negative pressure state, and ensure that the suction cup continues to effectively adsorb.

[0035] Furthermore, the second through hole 133 is located below the first air channel 132; the first air channel 132 is connected to the second air channel 112 through the second through hole 133. The airflow can be guided more effectively, and the positive pressure gas in the first air channel 132 can be introduced into the second air channel 112, so that the negative pressure effect of the adsorption groove 14 can be enhanced, so that the suction cup can more firmly adsorb the mobile phone screen.

[0036] Furthermore, the air outlet end of the second air channel 112 is connected to the first air pipe 15 through the first connecting head 18; the air outlet end of the third air channel 113 is connected to the second air pipe 17 through the second connecting head 19; this helps to improve the sealing of the connection part and reduce gas leakage, thereby maintaining the adsorption force of the suction cup; the first connecting head 18 and the second connecting head 19 are both located at the same end of the suction cup body 11; it can be convenient for users to operate and control, and the structure is more compact and the space utilization is reasonable.

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

[0038] Furthermore, the suction cup body 11 is provided with a plurality of third through holes 118 on the periphery of the groove 111; the upper surface of the suction cup body 11 is also provided with a transition groove 119 connecting the third through holes 118 and the groove. This helps to improve the smoothness of the airflow, so that the suction cup is smoother during the adsorption and release process; the bottom of the suction cup body 11 is also provided with a positioning groove 1110 on the periphery of the groove 111, so as to facilitate the connection with external components; the plurality of third through holes 118 are all located in the positioning groove 1110. Placing the third through holes 118 on the periphery of the groove 111 can help the air flow in and out more evenly, thereby forming a 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 of the suction cup is evenly distributed during adsorption, reduce the situation of local overpressure or underpressure, and protect the mobile phone screen or other adsorption surfaces.
