[0037] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0038] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0039] It should be noted that the terms "first," "second," "third," etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate to facilitate the embodiments of the present invention described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units that are not explicitly listed or are inherent to these processes, methods, products, or apparatuses.

[0040] In the prior art, the gas discharged by the vacuum pump of the electric suction cup cannot be discharged from the handle effectively and quickly, resulting in increased air pressure in the handle, which in turn leads to problems such as poor exhaust, low suction efficiency and loud working noise of the electric suction cup.

[0041] In view of this, the present invention provides an electric suction cup handle 1, such as Figures 1 to 3 As shown, it includes a shell 11, an air intake assembly 12, and a vacuum pump assembly 13. The air intake assembly 12 and the vacuum pump assembly 13 are installed in the shell 11; the air intake assembly 12 and the air inlet of the vacuum pump assembly 13 are connected through a pipeline; an exhaust hole 111 is opened on the shell 11, and the air outlet of the vacuum pump assembly 13 is connected to the external air through the exhaust hole 111.

[0042] The present invention provides an electric suction cup handle 1, which is provided with an exhaust hole 111, so that the gas discharged by the vacuum pump can be discharged from the handle 1 through the exhaust hole 111, thereby reducing the internal air pressure of the handle 1, thereby solving the problems of poor exhaust, low suction efficiency and high working noise.

[0043] In order to allow the gas discharged from the vacuum pump to be completely and efficiently discharged from the handle 1, Figure 3As shown, it also includes an exhaust pipe 141, one end of the exhaust pipe 141 is connected to the air outlet of the vacuum pump assembly 13, and the other end is connected to the exhaust hole 111. Specifically, the exhaust pipe can pass through the exhaust hole directly, or it can be connected to the exhaust hole to achieve exhaust. Such an arrangement allows the gas discharged by the vacuum pump to be discharged from the handle 1 directly through the exhaust assembly 14 along the exhaust pipe 141. At the same time, since the electric suction cup is in a dusty working environment, dust will gradually accumulate in the air intake assembly, and the accumulation of dust will become difficult to clean, causing wear and tear on the precision components inside the suction cup 2, and even causing the air intake assembly 12 to be blocked, affecting the normal operation of the suction cup 2, shortening the service life of the equipment, and causing serious faults such as air leakage in the suction cup 2. In order to clean the air intake assembly 12, the suction cup 2 is immersed in the cleaning liquid and started, and the vacuum pump assembly 13 runs for a certain time to clean the residue in the air intake assembly and discharge it from the handle through the exhaust pipe; then the suction cup 2 is taken out of the cleaning liquid and runs in the air for a certain time to dry the pipeline, so as to discharge the cleaning liquid in the handle from the exhaust pipe, thereby completing the cleaning of the air pipeline inside the electric suction cup.

[0044] In order to prevent external dust from entering the interior of the handle 1, according to an embodiment of the present invention, Figure 2 As shown, the housing 11 further includes an exhaust assembly 14, which is installed in the exhaust hole 111 and communicates with the end of the exhaust pipe 141 away from the vacuum pump. This arrangement prevents external dust from entering either the interior of the housing 11 or the interior of the exhaust pipe 141, thereby improving the working environment quality of the vacuum pump assembly 13 and extending the service life of the electric suction cup.

[0045] In the above description, to facilitate cleaning or replacement of the exhaust assembly 14, in one embodiment of the present invention, one end of the exhaust assembly 14 that is in contact with the outside air is detachably connected to the housing 11. To facilitate the removal, installation, and maintenance of the exhaust assembly 14, in a more preferred embodiment of the present invention, the detachable connection is a threaded connection. The exhaust assembly 14 includes an exhaust pipe 141, an axial through hole is provided in the exhaust pipe 141, and threads are machined on the outer wall of the exhaust pipe 141. The housing 11 is provided with an internal thread that cooperates therewith, or an independent nut that cooperates with the exhaust pipe 141 is provided inside. The exhaust assembly 14 is threadedly connected to the housing 11, preferably using a pipe thread with good airtightness. To better prevent external dust from entering the interior of the handle 1, the aperture of the through hole of the exhaust pipe 141 at one end near the vacuum pump is larger than the aperture at the other end. Furthermore, a one-way valve is provided on the exhaust pipe 141.

[0046] According to another embodiment of the present invention, Figure 3As shown, the housing 11 further includes an exhaust assembly 14. An exhaust cavity 112 is provided within the housing 11. The cavity of the exhaust cavity 112 forms a closed space. The exhaust hole 111 passes through the cavity of the exhaust cavity 112. The exhaust assembly 14 is mounted on the cavity of the exhaust cavity 112. Only a small portion of external dust can enter the exhaust cavity 112, and this portion of dust will be blown out of the exhaust cavity 112 when the vacuum pump is exhausted.

[0047] In order to keep the suction cup surface or the operator's hands clean, Figure 1 As shown, the shell 11 includes two fixing parts 113 and a connecting part 114, and the fixing parts 113 are arranged at both ends of the connecting part 114; preferably, the fixing parts 113 and the connecting part 114 are arranged integrally. The exhaust hole 111 is arranged on one of the fixing parts 113 and is arranged toward the other fixing part 113. Preferably, the exhaust hole 111 is arranged at one end of the fixing part 113 away from the connecting part 114. Such an arrangement allows the gas discharged from the exhaust hole 111 to blow from one fixing part 113 to the other fixing part 113, thereby keeping the surface of the suction cup or the operator's hands clean, thereby increasing the adsorption stability of the suction cup or improving the operator's work efficiency.

[0048] In one embodiment, the air intake assembly 12 includes an air intake pipe 122, which is connected to the vacuum pump assembly 13. Specifically, one end of the air intake pipe 122 is connected to the air inlet of the vacuum pump, and the other end is connected to the interior of the suction cup.

[0049] In order to better detect the air pressure value of the air sucked into the hollow inner cavity 123 and to better control the electric suction cup to work, in one embodiment of the present invention, Figure 3 As shown, the air intake assembly 12 includes a gas diversion structure 121, an air pressure detection module and a pressure relief solenoid valve. A hollow inner cavity 123 is formed inside the gas diversion structure 121. The gas diversion structure 121 also includes an outlet pipe 124, an air pressure detection pipe 125 and a pressure relief pipe 126 that are in communication with the hollow inner cavity 123. The air pressure detection pipe 125 is connected to the air pressure detection module pipeline; the pressure relief pipe 126 is connected to the pressure relief solenoid valve pipeline.

[0050] One end of the air outlet pipe 124 is connected to the air inlet pipe 122 through the hollow inner cavity 123, and the other end is connected to the air inlet of the vacuum pump assembly 13. As shown in the figure, in order to more accurately obtain pressure values ​​for control, in a preferred embodiment of the present invention, the air pressure detection module is provided with a pressure sensor, preferably a piezoresistive sensor, which collects air pressure signals and transmits them to the control module of the electric suction cup.

[0051] In order to filter the dust in the inhaled air and protect the devices in the air pipeline, in one embodiment of the present invention, a filter element is provided in the hollow inner cavity 123 of the gas diversion structure 121. For example, when the dust content in the inhaled air is too high, it has a strong destructive effect on the one-way valve in the air pipeline and even causes the one-way valve to fail. In a more preferred embodiment of the present invention, the filter element includes microporous filter paper or non-woven fabric, activated carbon. In order to allow the inhaled dusty air to be effectively filtered in the hollow inner cavity 123 of the gas diversion structure 121, the gas diversion structure 121 includes a gas diverter. During assembly, ensure that the filter element can be tightly and detachably installed in the hollow inner cavity 123 and will not loosen or move under normal working conditions, thereby ensuring the stability and sealing of the filter element in the gas diversion structure 121 and preventing unfiltered air from bypassing the filter element and entering the system.

[0052] To reduce backflow of inhaled air in the electric suction cup air line, in one embodiment of the present invention, a pressure-maintaining device is provided on the pipe connecting the air intake assembly 12 and the vacuum pump assembly 13, and / or on the pipe connecting the exhaust assembly 14 and the vacuum pump assembly 13. The pressure-maintaining device comprises a one-way valve or a solenoid valve. Preferably, the one-way valve comprises a duckbill valve. To more precisely control the opening and closing of the air line, a solenoid valve is preferably used.

[0053] In order to better control the start and stop of the vacuum pump assembly 13, in one embodiment of the present invention, the handle 1 further includes a control module fixedly connected to the inner wall of the housing 11, such as Figure 4 As shown, the control module is electrically connected to the vacuum pump assembly 13. The solenoid valve, the pressure relief solenoid valve, and the air pressure detection module are each electrically connected to the control module. To better secure the control module within the electric suction cup handle 1, in a more preferred embodiment of the present invention, the control module, the vacuum pump assembly 13, and the pressure maintaining device are all fixedly connected to the inner wall of the housing 11 via a snap-fit ​​connection.

[0054] In addition, the present invention also provides an electric suction cup, comprising the electric suction cup handle 1 and the suction cup 2 described in the present invention, the suction cup is fixedly connected to the electric suction cup handle 1, and the air intake assembly 12 is connected to the suction cup 2.
