[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figure 1-6 The handheld microporous suction cup includes a carrier ring 1, a handle 2 fixed to the outer edge of the carrier ring 1, an adsorption ring 3 installed on the top surface of the carrier ring 1, and micropores evenly opened on the surface of the adsorption ring 3.

[0027] The carrier ring 1 has a groove 11, and the adsorption ring 3 is embedded in the groove 11;

[0028] An air channel 21 is provided on the inner side of the handle 2, and an air inlet 111 is provided at the bottom of the groove 11, and the air inlet 111 is connected to the air channel 21.

[0029] The end of the handle 2 away from the carrier ring 1 is equipped with an air pipe connector 4. The open end of the air pipe connector 4 is used to connect to an external negative pressure suction device. The end of the air guide channel 21 away from the air inlet 111 is provided with an air guide hole 24, and is connected to the inside of the air pipe connector 4 through the air guide hole 24.

[0030] By adopting the above technical solution, through the integrated design of the carrier ring 1 and the handle 2, combined with the microporous structure of the adsorption ring 3 and the connection of the air passage, the negative pressure generated by the external negative pressure suction device can be sequentially transmitted to the surface of the adsorption ring 3 through the air pipe connector 4. The uniform distribution of micropores forms a stable adsorption force, which can smoothly grasp thin or fragile workpieces, replacing traditional mechanical clamping or human hand contact, avoiding workpiece breakage and deformation caused by mechanical force, and completely eliminating the contamination caused by human hand contact, thus meeting the requirements of clean operation.

[0031] The carrier ring 1 and handle 2 are made of carbon fiber material, and the adsorption ring 3 is made of silicon carbide microporous ceramic material.

[0032] The micropores on adsorption ring 3 have an inner diameter of 5-10 μm.

[0033] Using the above technical solutions, the carrier ring 1 and handle 2 are made of carbon fiber material, which greatly reduces the overall weight while ensuring structural strength and improving the flexibility of hand operation; the adsorption ring 3 is made of silicon carbide microporous ceramic material, which is suitable for various working conditions due to its high temperature resistance and wear resistance, and the micropore inner diameter of 5-10μm can form a uniform and moderate adsorption force, which can firmly adsorb the workpiece without leaving indentations on the workpiece surface due to excessive pore size.

[0034] The bottom edge of the groove 11 is provided with an inner ring 12. The height of the inner ring 12 is lower than the height of the outer ring at the top of the groove 11, forming a downward step structure. The bottom end of the adsorption ring 3 is installed on the top surface of the inner ring 12.

[0035] By adopting the above technical solution, the inner ring 12 and the outer ring at the top of the groove 11 form a stepped structure. On the one hand, it provides a precise installation positioning reference for the adsorption ring 3, ensuring that the top surface of the adsorption ring 3 is flush with the top surface of the carrier ring 1 after assembly, thus ensuring the flatness of the adsorption surface. On the other hand, the setting of the inner ring 12 creates a gap between the bottom surface of the adsorption ring 3 and the bottom surface of the groove 11, providing space for gas flow and ensuring smooth gas path connection.

[0036] The annular space inside the groove 11 is equipped with protrusions 13 arranged in a ring array. The protrusions 13 fit the bottom surface of the adsorption ring 3, and the size of the protrusions 13 gradually decreases from the inside of the groove 11 towards the inner ring.

[0037] Using the above technical solution, the protrusions 13 arranged in a ring array on the inner side of the groove 11 are attached to the bottom surface of the adsorption ring 3, providing uniform and stable support for the adsorption ring 3. This can effectively counteract the downward pressure generated during negative pressure adsorption and prevent the adsorption ring 3 from deforming due to force, thus affecting the flatness of the adsorption surface. At the same time, the intervals between the protrusions 13 form a gas flow channel, ensuring that the negative pressure gas can flow smoothly.

[0038] The bottom end of the carrier ring 1 has multiple sets of circular weight-reducing grooves 14 arranged in a ring array, the top surface of the handle 2 has a second strip-shaped weight-reducing groove 23 in the middle, and the bottom surface of the handle 2 has a first strip-shaped weight-reducing groove 22 on both sides.

[0039] By adopting the above technical solutions, the circular weight reduction groove 14 at the bottom of the carrier ring 1 and the strip weight reduction groove of the handle 2 further reduce the overall weight without affecting the structural strength. The lightweight structure allows operators to hold the device for a long time without fatigue, thus improving work efficiency.

[0040] Working principle:

[0041] The external negative pressure suction device is connected through the air pipe connector 4. The negative pressure enters the air channel 21 of the handle 2 through the air guide hole 24, and then enters the interior of the groove 11 through the air inlet hole 111 at the bottom of the groove 11. Utilizing the microporous structure on the surface of the adsorption ring 3, the negative pressure forms a uniform adsorption force on the contact surface between the adsorption ring 3 and the workpiece, thereby achieving stable adsorption of the workpiece.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
