DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions of the present utility model in combination with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] The following will, in combination with the drawings, detail the technical solutions provided by each embodiment of the present utility model.

[0023] Refer to Figures 1 to 2 As shown, an electric suction cup integrating functions of filtration, positive pressure, and negative pressure vacuum is provided in an embodiment of the present utility model, including a main body housing 1. A main body bottom cover 6 is provided at the bottom of the main body housing 1. A micro diaphragm pump 3 and two solenoid valves 4 are provided inside the main body housing 1. The two solenoid valves 4 are respectively arranged at both ends of the micro diaphragm pump 3. An air inlet is provided on the main body bottom cover 6, and a sealing ring 7 and a filter element are provided inside the air inlet. The sealing ring 7 can ensure that air will not leak out when passing through the filter cotton 8. A multi-nozzle adapter plate 9 is provided below the main body bottom cover 6. A detachable suction cup fitting 10 is provided on the multi-nozzle adapter plate 9, and a silicone suction cup 11 is provided on the suction cup fitting 10. The two solenoid valves 4 are respectively an air inlet solenoid valve and an air outlet solenoid valve.

[0024] During the use process,

[0025] Air inlet process:

[0026] The air inlet solenoid valve is opened, and the air outlet solenoid valve is closed:

[0027] When the air inlet solenoid valve is energized and opened, the channel for external gas is opened. At this time, the air outlet solenoid valve is in a closed state, and gas can only enter the quick connector from the air inlet solenoid valve.

[0028] The diaphragm inside the micro diaphragm pump 3 moves driven by a motor or other driving device. When the diaphragm moves backward, the volume of the pump chamber increases, forming a negative pressure.

[0029] Due to the opening of the air inlet solenoid valve, external gas enters the pump chamber of the micro diaphragm pump 3 under the action of the negative pressure.

[0030] The air inlet solenoid valve is closed, and the air outlet solenoid valve is closed:

[0031] When the silicone suction cup 11 does not need to intake air, the air inlet solenoid valve is de-energized and closed. At this time, external gas cannot enter the quick connector.

[0032] The air outlet solenoid valve remains closed, and the gas in the micro diaphragm pump 3 is temporarily sealed in the pump chamber. This can maintain the pressure stability in the quick connector under some specific working scenarios, or prevent gas leakage and entry of external impurities during the equipment suspension period.

[0033] Air outlet process:

[0034] The intake solenoid valve is closed and the air outlet solenoid valve is opened:

[0035] When it is necessary to discharge the gas in the micro diaphragm pump 3, the intake solenoid valve remains closed, and the air outlet solenoid valve is energized and opened.

[0036] The diaphragm of the micro diaphragm pump 3 moves forward, the volume of the pump chamber decreases, the gas is compressed, and the pressure rises.

[0037] Since the air outlet solenoid valve is opened, the compressed gas is discharged from the pump chamber through the air outlet solenoid valve to the quick connector.

[0038] During the use process, after the silica gel suction cup 11 adsorbs the required material, the micro diaphragm pump 3 works to generate negative pressure, thereby performing negative pressure adsorption work on the material.

[0039] In this embodiment, the filter element is a filter cotton 8; the filter cotton 8 is a PP filter cotton; when air passes through the filter cotton 8, most of the dust and debris can be filtered, preventing dust or debris in the air from entering the micro diaphragm pump 3 and causing damage to the micro diaphragm pump 3.

[0040] PP filter cotton can achieve high-precision filtration: The filtration accuracy of PP filter cotton is relatively high, which can effectively remove particulate impurities in water, such as large particulate matters like rust, sediment, and insect eggs, and can also filter out colloidal impurities and micro mud with a diameter greater than 5 microns in tap water. After multiple layers of filtration, the closer to the filter element layer, the smaller the pore size and the higher the filtration accuracy, and it also has a good interception effect on some tiny particles 1.

[0041] The bridging effect intercepts impurities: When particulate impurities pass through the pore channels of the PP filter cotton 8, a bridging phenomenon will occur. Even if the particles are smaller than the pore channels, they can be blocked, so that various particulate impurities in the filtered air can be deeply removed.

[0042] In this embodiment, the outer surface of the suction cup fitting 10 is provided with an external thread groove, the multi-nozzle adapter plate 9 is provided with an internal thread groove, and the suction cup fitting 10 is threadedly connected to the internal thread groove through the external thread groove.

[0043] During the use process, the suction cup fitting 10 can be screwed onto the multi-nozzle adapter plate 9, and when not in use, the suction cup fitting 10 can be disassembled from the multi-nozzle adapter plate 9, which is convenient for transportation and placement. The threaded connection is convenient, fast for disassembly and installation.

[0044] In this embodiment, two silicone gaskets 5 are provided on the micro diaphragm pump 3, and the air inlet end and the air outlet end of the micro diaphragm pump 3 are respectively connected to the main body bottom cover 6 through the silicone gaskets 5; the setting of the silicone gaskets 5 ensures that the micro diaphragm pump 3 will not leak air during use, affecting the use.

[0045] In this embodiment, the multi-nozzle adapter plate 9 is connected to the main body bottom shell by four screws. After the filter cotton 8 filters the air for a period of time, the multi-nozzle adapter plate 9 can be removed from the main body bottom shell by removing the four screws to replace and clean the filter cotton 8 or the sealing ring 7.

[0046] In this embodiment, an operation indicator light 2 is provided on the main body housing 1; the operation indicator light 2 can indicate whether the electric suction cup is working properly.

[0047] In this embodiment, a cable 12 is provided on the main body housing 1; the cable 12 supplies power to and controls the micro diaphragm pump 3 and the two solenoid valves 4, and can control the switching of the positive pressure and negative pressure of the electric suction cup with one key during use.

[0048] The above are only the embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
