[0036] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clear, this application is further described in detail below with reference to the accompanying drawings and embodiments.

[0041] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the quantity of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0042] In the description of the present application, “plurality” means two or more, unless otherwise clearly defined.

[0043] In order to solve the technical problem that the vacuum adsorber in the prior art has a contact method that easily affects the stability of the startup, resulting in reduced stability and reliability when starting the vacuum adsorber; for this purpose, an embodiment of the present utility model provides a vacuum adsorber.

[0044] The following describes in detail the specific structure of a vacuum adsorber provided by the embodiment of the present invention. Figure 1-6 As shown in FIG, the specific structure of the vacuum adsorber includes an outer shell 1, an integrated vacuum pump 2, a control panel 3, a starting assembly 4 and a trigger 5.

[0045] The outer shell 1 is hollow to form a receiving cavity 11 and an opening 14 communicating with the receiving cavity 11 .

[0046] Specifically, the integrated vacuum pump 2, the control panel 3 and the starting assembly 4 are all built into the accommodating chamber 11. The accommodating chamber 11 is used to accommodate core components such as the integrated vacuum pump 2, the control panel 3 and the starting assembly 4, ensuring that they can operate in a closed and well-protected environment to prevent other external objects from colliding with such components and causing damage. Moreover, when the trigger member 5 is set in the opening 14, such components are encapsulated in the same sealed accommodating chamber 11 to prevent external dust, moisture and other pollutants from entering the interior of the outer shell 1.

[0047] The integrated vacuum pump 2 is built into the accommodating chamber 11. Specifically, since the motor of the existing vacuum pump is separately provided with the vacuum pump, the vacuum pump draws vacuum by means of a piston, and an eccentric wheel is provided on the motor, and the vacuum pump is driven by the piston rod. The integrated vacuum pump 2 of the embodiment of the present invention drives the diaphragm inside the pump to perform reciprocating motion through the eccentric wheel device, thereby compressing or stretching the air in the pump chamber, thereby forming a vacuum effect; specifically, when the diaphragm moves inward, the gas in the pump chamber is compressed, the exhaust port opens, the suction port closes, and the gas in the pump chamber is discharged; when the diaphragm moves outward, negative pressure is formed, the exhaust port closes, and the suction port opens, thereby sucking the gas in the suction cup into the pump chamber; it can be seen that by providing a diaphragm, the effects of no lubrication, low leakage, and strong sealing can be achieved, and the noise generated during operation can be reduced.

[0048] The control board 3 is built into the accommodating cavity 11 , and the control board 3 is control-connected to the integrated vacuum pump 2 ; the control board 3 is control-connected to a photoelectric switch 31 .

[0049] Specifically, the control board 3 is the core control component of the entire system, which can receive and input signals, process the received signals according to a preset program or algorithm, and then output a control signal to drive the integrated vacuum pump 2; the photoelectric switch 31 is a non-contact sensor that operates using the photoelectric effect. When the photoelectric switch 31 is sensing, it can send an electrical signal, and the control board 3 receives the electrical signal sent by the photoelectric switch 31. Finally, the control board 3 outputs a high-level signal to start the operation of the integrated vacuum pump 2.

[0050] It should be noted that the circuits and processors on the control board 3 are capable of receiving, processing and analyzing received signals, and then outputting corresponding control instructions, thereby achieving control over the integrated vacuum pump 2 .

[0051] according to Figure 1-Figure 3 As shown, the starting component 4 includes a guide member 41 and a light-shielding movable part 42; the guide member 41 is built into the accommodating cavity 11, and the guide member 41 is hollow to form a movable cavity 411, and the cavity wall of the movable cavity 411 is penetrated by a light-transmitting port 423, and the light-shielding movable part 42 is movably arranged in the movable cavity 411.

[0052] Specifically, in order to start the operation of the integrated vacuum pump 2, the light irradiation state of the photoelectric switch is controlled by the light shading movable part 42. Specifically, the trigger part 5 can be used to push the light shading movable part 42 to move axially along the guide part 41 in the active cavity 411. The photoelectric switch 31 provided on the control board 3 includes an emitting sensing end 311 and a receiving sensing end 311. Under certain conditions, the light is stably irradiated in a certain direction. When the light shading movable part 42 moves to block the irradiation of light, the light irradiation state of the light shading movable part 42 changes, which then triggers a voltage change inside the photoelectric switch. Once the control board 3 detects a change in the voltage change signal, such as the type and amplitude of the voltage change signal, the signal is immediately identified and processed. The control board 3 can respond quickly and finally control the operation of the integrated vacuum pump 2.

[0053] It should also be noted that the photoelectric switch is composed of a photoresistor (such as a photodiode), and its working principle is that when light shines through the light-transmitting port 423 of the active cavity 411 and shines on the photoresistor, it causes its resistance value to change; conversely, when the light-shielding baffle moves in the active cavity 411 to block the light path of the photoelectric switch, the photoelectric switch 31 will not be able to receive light, causing its resistance value to change, thereby generating a voltage change, and finally, according to the instructions of the control board 3, the integrated vacuum pump 2 is controlled to start operation.

[0054] according to Figure 1 As shown, the trigger member 5 is covered in the opening 14 of the outer shell 1 and is used to push the light shielding movable portion 42 to move.

[0055] Specifically, when the user presses the trigger 5 directly with his finger or through other components that assist in pressing, the trigger 5 pushes the entire light-shielding movable portion 42 to move in the active cavity 411 to block the light path of the photoelectric switch.

[0056] according to Figure 4 As shown, in some specific embodiments, at least a portion of the sensing end 311 of the photoelectric switch 31 is disposed outside the control board 3 and can face the light-transmitting port 423 .

[0057] Specifically, in order to improve the internal space utilization of the accommodating cavity 11, a plurality of avoidance holes are passed through the control board 3. The sensing end 311 of the photoelectric switch 31 arranged on the side of the control board 3 passes through the avoidance hole from the front side of the control board 3 to its back side, and at least part of the sensing end 311 passes through the back side of the control board 3, so that the sensing direction of the sensing end 311 of the photoelectric switch 31 can be toward the light-transmitting port 423. With this arrangement, it can normally receive and transmit light signals from the light-transmitting port 423 to achieve accurate sensing operation, and it can also avoid the additional space occupied by the sensing end 311 on the control board 3, thereby improving the internal space utilization of the accommodating cavity 11.

[0058] according to Figure 3 As shown, in some specific embodiments, a stepped end 412 is provided on the cavity wall of the active cavity 411, and a protrusion 421 for abutting against the stepped end 412 is provided on the outer wall of the light-shielding movable portion 42 to limit the moving distance of the light-shielding movable portion 42.

[0059] Specifically, a limiting effect is formed when the stepped end 412 and the raised portion 421 are in contact with each other. Specifically, in order to prevent the photoelectric switch 31 from receiving light, causing its resistance value to change, when the light-shielding movable portion 42 moves to the sensing end 311 of the photoelectric switch 31 to receive light, the raised portion 421 of the light-shielding movable portion 42 is in contact with the stepped end 412, thereby preventing the light-shielding movable portion 42 from continuing to move. The limiting effect achieved by physical contact ensures that the light-shielding movable portion 42 can only move within a predetermined range, thereby preventing the light-shielding movable portion 42 from excessive displacement or falling off.

[0060] It is understandable that the aforementioned protrusions 421 are provided in plurality, for example, two protrusions 421 are provided, and the side surfaces of each protrusion 421 slide against the cavity wall of the active cavity 411, further improving the stability of the entire light-shielding movable portion 42 when it moves in the active cavity 411.

[0061] according to Figure 2 and Figure 3 As shown, in some specific embodiments, an elastic member is provided in the movable cavity 411 for pushing the light shielding movable portion 42 to reset and move.

[0062] Specifically, when the elastic member is a spring and the trigger member 5 is not pressed, the spring will push the light-shielding movable portion 42 to move along the direction of the trigger member 5 in the process of restoring its original shape until the light-shielding movable portion 42 is reset to a position where it no longer blocks light.

[0063] according to Figure 5As shown, in some specific embodiments, the cavity wall of the movable cavity 411 is formed with a first straight surface 413 , and the outer side wall of the light shielding movable portion 42 is formed with a second straight surface 422 for contacting with the straight surface.

[0064] Specifically, if the active cavity 411 is set as a cylindrical cavity and the light-shielding movable part 42 is cylindrical, it is easy for the light-shielding movable part 42 to shake in the circumferential direction when moving; therefore, the first straight surface 413 of the active cavity 411 and the second straight surface 422 of the light-shielding movable part 42 are both straight planes formed by precise processing to ensure the accuracy of the fit between the two. When the light-shielding movable part 42 moves in the active cavity 411, the second straight surface 422 fits tightly with the first straight surface 413, which effectively prevents the light-shielding movable part 42 from shaking in the circumferential direction, thereby preventing the light-shielding movable part 42 from moving radially and circumferentially in the cavity. Moreover, the cooperation between the first straight surface 413 and the second straight surface 422 helps to enhance the overall structural strength of the active cavity 411. When the light-shielding movable part 42 moves in the active cavity 411, the first straight surface 413 and the second straight surface 422 jointly bear a certain load.

[0065] according to Figure 3 As shown, in some specific embodiments, a positioning plate 12 is provided in the accommodating cavity 11 , and the guide member 41 is detachably provided on a side surface of the positioning plate 12 .

[0066] Specifically, in order to improve the convenience of the guide member 41 during the disassembly and assembly process and simplify the maintenance and disassembly process, when the guide member 41 needs to be replaced or repaired, it is only necessary to remove the guide member 41 from the positioning plate 12.

[0067] according to Figure 3 As shown, specifically, a positioning column 121 is provided on the side of the positioning plate 12, and the positioning column 121 is provided with a fixing hole; the guide member 41 is penetrated by a locking hole for corresponding communication with the fixing hole; the vacuum adsorber also includes a locking member, when the locking member is simultaneously passed through the locking hole and the fixing hole, the guide member 41 is fixed.

[0068] Specifically, in order to improve the convenience of the guide member 41 during the disassembly and assembly process, when assembling the guide member 41, it is only necessary to connect the locking hole on the guide member 41 with the locking hole of the positioning column 121, and then insert the locking member into the locking hole and the fixing hole at the same time so that the guide member 41 can be fixed on the positioning plate 12. This arrangement improves the convenience of the guide member 41 during assembly; conversely, when disassembling the guide member 41, it is only necessary to detach the locking member from the fixing hole and the locking hole, and then the guide member 41 can be directly taken out.

[0069] It can be understood that the locking member of the embodiment of the present invention is a bolt, and the fixing hole and the locking hole are both threaded holes. By connecting the thread of the bolt with the thread of the two threaded holes, it is difficult for the bolt to loosen or fall off, so that the guide member 41 is fixedly assembled on the positioning plate 12, thereby improving the firmness of both.

[0070] according to Figure 3 As shown, in some specific embodiments, the trigger member 5 includes a cover plate 51 covering the opening 14 and a button cap 52 arranged on the side of the cover plate 51 away from the accommodating cavity 11; the button cap 52 is close to the inner side of the accommodating cavity 11 and abuts against the light-shielding movable portion 42.

[0071] Specifically, the cover 51 is used to cover part of the opening 14 to protect the internal components from interference from external factors such as dust and moisture. The raised portion 421 of the key cap 52 sets the cover 51 away from the side of the accommodating cavity 11. Therefore, when the key cap 52 is pressed, the key cap 52 is squeezed toward the light-shielding movable portion 42. During this process, the inner side of the key cap 52 comes into contact with the light-shielding movable portion 42. Since the light-shielding movable portion 42 is movably arranged in the active cavity 411, the position of the light-shielding movable portion 42 changes with the operation of the key cap 52. Therefore, when the key cap 52 comes into contact with the light-shielding movable portion 42, it pushes the entire light-shielding movable portion 42 to move in the active cavity 411.

[0072] In order to achieve close contact between the key cap 52 and the light shielding movable part 42, a concave-convex structure is provided on the key cap 52 and the light shielding movable part 42, thereby ensuring that the key cap 52 can be closely fitted with the light shielding movable part 42 when pressure is applied.

[0073] In a further embodiment, the cover plate 51 and the key cap 52 are both softly configured; specifically, when the key cap 52 is pushed, the cover plate 51 and the key cap 52 made of soft material may both deform to a certain extent, thereby generating a driving force that can push the light-shielding movable portion 42 to move, so that the light-shielding movable portion 42 can move in the active cavity 411, and the cover plate 51 and the key cap 52 made of soft material have good elasticity and recovery. When the pressure pushing the key cap 52 disappears, the key cap 52 and the cover plate 51 can both return to their original state, thereby achieving reset.

[0074] It should be noted that the cover plate 51 and key cap 52, made of a soft material, have strong shock absorption and cushioning properties, effectively absorbing external vibrations and shocks, reducing the impact on internal components. When the key cap 52 is pushed, the soft rubber material of the cover plate 51 and key cap 52 helps to alleviate the impact of the key being pressed, reducing damage to internal components.

[0075] It is understandable that the cover plate 51 and the button cap 52 of the embodiment of the present invention are made of materials such as thermoplastic elastomer, thermoplastic polyurethane elastomer, methyl vinyl silicone rubber or polyvinyl chloride, and the specific type is not limited here.

[0076] according to Figure 6 As shown, in some specific embodiments, the integrated vacuum pump 2 is provided with an air inlet pipe 21; the cavity wall of the accommodating cavity 11 is penetrated by a through hole 13 connected to the air inlet pipe 21. Thus, the air inlet pipe 21 of the integrated vacuum pump 2 is directly connected to the external device through the through hole 13, avoiding too many holes between the two and causing more leakage points, thereby further improving the overall sealing.

[0077] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
