The adsorption device is provided with a trigger button, a movable trigger piece, a first fixed trigger piece and a second fixed trigger piece in a suction cup; when a sucker is fixed to a to-be-adsorbed plane, a user presses the sucker to the to-be-adsorbed plane, so that the plane presses a trigger button to drive a movable trigger piece to move and break away from an abutted second fixed trigger piece, and at the moment, an air pump starts to work to extract air between the sucker and an adsorption surface; along with continuous pressing, the movable triggering piece is finally made to abut against the first fixed triggering piece, and at the moment, the air pump is closed to complete adsorption; when the suction cup leaks air, as the air pressure difference between the inner side and the outer side of the suction cup is reduced, and the pressing force generated by the plane to be adsorbed to the trigger button is also reduced, the movable trigger piece moves and is separated from the first fixed trigger piece which is propped against the movable trigger piece, and at the moment, the control panel controls the air pump to restart to work so as to ensure that the suction cup has relatively high adsorption capacity all the time.

Description

Technical Field

[0001] This utility model relates to the field of adsorption device technology, and more specifically, to an adsorption device and a portable mobile lamp. Background Technology

[0002] In some cases, in order to facilitate user operation or to fix objects, it is often necessary to use an adsorption device to adsorb and fix the objects.

[0003] Taking portable mobile lights as an example, existing portable mobile lights typically adopt a handheld structure, requiring the user to hold them during use. This limits the user's freedom of operation in some scenarios because they cannot free their hands. In such cases, an adsorption device can be used to fix the mobile light in the working environment, thereby improving the user's ease of operation.

[0004] Existing adsorption devices generally use magnets or suction cups. However, the magnetic fixation of magnets requires a magnetic metal in the working environment, while the use of suction cups has relatively lower environmental requirements, only requiring a flat surface with a certain degree of smoothness.

[0005] The principle of suction cup adsorption is to create a pressure difference between the inside and outside of the suction cup by expelling the air between the suction cup and the surface, thus achieving adsorption and fixation. Current methods for expelling air generally fall into two categories: manual squeezing and vacuuming. Manual squeezing, due to insufficient air expulsion, can easily cause the suction cup to loosen and detach. Vacuuming, on the other hand, may lead to air leakage after prolonged use, resulting in insufficient suction force and eventual detachment. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide an adsorption device and a portable mobile lamp to solve the above problems.

[0007] The present invention adopts the following solution:

[0008] This application provides an adsorption device, including a suction cup, an air extraction drive mechanism for extracting air from the suction cup, a control board electrically connected to the air extraction drive mechanism, a trigger button provided on the adsorption surface of the suction cup, a movable trigger connected to the trigger button, and a first fixed trigger and a second fixed trigger electrically connected to the control board.

[0009] When the trigger button is not pressed, the movable trigger abuts against the second fixed trigger; when the trigger button is pressed, the trigger button causes the movable trigger to move based on the pressing force, so as to disengage from the second fixed trigger and gradually approach the first fixed trigger until it abuts against the first fixed trigger.

[0010] When the movable trigger abuts against the first fixed trigger or the second fixed trigger, the control board generates a first electrical signal to control the air extraction drive mechanism to be in a non-working state. When the movable trigger is not abutting against either the first fixed trigger or the second fixed trigger, the control board generates a second electrical signal to control the air extraction drive mechanism to be in a working state.

[0011] Furthermore, the active trigger member is provided with a first trigger part and a second trigger part along a direction perpendicular to the movement direction; the two fixed trigger members are respectively provided with fixed trigger parts corresponding to the first trigger part and the second trigger part along a direction perpendicular to the movement direction, and are arranged intersecting with the first trigger part and the second trigger part.

[0012] Furthermore, the active trigger, the first fixed trigger, and the second fixed trigger are formed by bending a stylus; and the fixed trigger is L-shaped.

[0013] Furthermore, the control board is provided with a limiting groove for the passage of the active trigger.

[0014] Furthermore, the suction cup is integrally formed and fixed to the housing; the housing has a mounting hole at its center; the trigger button is mounted on the mounting hole via a bracket fixed inside the housing, and one end protrudes into the suction cup; the housing also has an air hole communicating with the suction cup; the bracket and the housing are sealed to form an air cavity communicating with the air hole.

[0015] Furthermore, the air extraction drive mechanism includes an exhaust passage communicating with the exhaust port of the air pump, and an intake passage communicating with the air inlet of the air pump and the air chamber; a first one-way valve is provided on the intake passage; and a second one-way valve is provided on the exhaust passage.

[0016] Furthermore, a pressure relief valve is provided upstream of the first one-way valve; the pressure relief valve includes a pressure relief rod, an elastic element, and a sealing element disposed on the pressure relief chamber of the intake passage; a pressure relief port is provided on the pressure relief chamber; the pressure relief rod includes a pressure relief part disposed in the pressure relief chamber, and an operating part with one end connected to the pressure relief part and the other end protruding outward through the pressure relief port; the elastic element is disposed on the pressure relief part and the bottom of the pressure relief chamber, and the sealing element for sealing the pressure relief port is disposed on the operating part and positioned between the pressure relief port and the pressure relief part.

[0017] This utility model also provides a portable mobile lamp, including a lamp body and the aforementioned adsorption device; the adsorption device is disposed on the lamp body.

[0018] Furthermore, a first magnetic element is provided at one end of the lamp body; a second magnetic element adapted to the first magnetic element is provided on the adsorption device, and the adsorption device is provided on the lamp body through the cooperation of the second magnetic element and the first magnetic element.

[0019] Furthermore, one end of the lamp body has a circular protrusion protruding outward; the first magnetic member is disposed inside the protrusion; and the other end of the lamp body has a rotatable lamp head disposed in a direction perpendicular to the axis of the protrusion.

[0020] By adopting the above technical solution, the present invention can achieve the following technical effects:

[0021] This invention provides an adsorption device and a portable mobile lamp. The adsorption device, through the arrangement of a trigger button, a movable trigger, a first fixed trigger, and a second fixed trigger in the suction cup, achieves the following: When the suction cup is fixed to the surface to be adsorbed, as the user presses the suction cup against the surface, the surface exerts a reverse pressing force on the trigger button, causing the movable trigger to move away from the surface. This causes the second trigger to disengage from the second fixed trigger. Upon detecting this disengagement, the control board generates a corresponding second signal to the air pump, causing the air pump to start working and extracting air between the suction cup and the adsorption surface. As the pressing continues, the movable trigger continues to move, eventually coming into contact with the first fixed trigger. Upon detecting this contact, the control board generates a corresponding first signal to the air pump, shutting off the air pump and completing the adsorption process. When the suction cup leaks air, the pressure difference between the inside and outside of the suction cup decreases, and the pressure exerted by the surface to be adsorbed on the trigger button also decreases. This causes the movable trigger to move closer to the surface and disengage from the first fixed trigger. When the control board detects this disengagement, it generates a corresponding second signal to the air pump, causing the air pump to restart to ensure that the suction cup always has a strong adsorption capacity.

Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] Example

[0038] Combination Figures 1 to 9 As shown, this embodiment provides an adsorption device, including a suction cup 1, an air extraction drive mechanism 2 for extracting air from the suction cup 1, and a control board 18 electrically connected to the air extraction drive mechanism 2; the adsorption surface of the suction cup 1 is provided with a trigger button 3; it also includes a movable trigger 5 connected to the trigger button 3; and a first fixed trigger 6 and a second fixed trigger 7 electrically connected to the control board 18.

[0039] When the trigger button 3 is not pressed, the movable trigger 5 abuts against the second fixed trigger 7; when the trigger button 3 is pressed, the trigger button 3 drives the movable trigger 5 to move based on the pressing force, so as to disengage from the abutting second fixed trigger 7 and gradually approach the first fixed trigger 6 until it abuts against the first fixed trigger 6.

[0040] When the movable trigger 5 abuts against the first fixed trigger 6 or the second fixed trigger 7, the air extraction drive mechanism 2 is in a non-working state; when the movable trigger 5 does not abut against either the first fixed trigger 6 or the second fixed trigger 7, the air extraction drive mechanism 2 is in a working state.

[0041] Specifically, such as Figures 1 to 4As shown, in this embodiment, the suction cup 1 is integrally formed and fixed to the housing 4, and has a recessed cavity into the housing 4 to form an adsorption surface, which is used to contact the plane to be adsorbed. The trigger button 3 includes a housing 8 that can elastically deform, and a trigger rod 9 disposed in the housing 8. The housing 4 has a mounting hole 10 at its center; the housing 8 is disposed on the mounting hole 10 by a bracket fixed in the housing 4, and one end protrudes into the suction cup 1. The housing 4 is also provided with an air hole 11 communicating with the suction cup 1; an air cavity 12 communicating with the air hole 11 is sealed between the bracket and the housing 4; the suction drive mechanism 2 includes an exhaust passage communicating with the exhaust port of the air pump, and an intake passage communicating with the air inlet of the air pump and the air cavity 12. In this embodiment, a sealing ring 13 is provided between the bracket and the housing 4; the housing 8 is made of silicone or rubber, and its bottom is provided with a full-circle protruding sealing part 14, the sealing ring 13 and the sealing part 14 sealing the air chamber 12. The bracket is provided with a through hole for the trigger rod 9 to move axially.

[0042] In this embodiment, the active trigger 5, the first fixed trigger 6, and the second fixed trigger 7 are formed by bending a stylus; as shown Figures 5 to 7 As shown, the upper side of the active trigger part has a first bent portion 15 connected to the lower end of the trigger rod 9, the middle has a second bent portion 16 protruding to the left, and the bottom has a third bent portion 17. The first fixed trigger member 6 and the second fixed trigger member 7 are both L-shaped; the first fixed trigger member 6 is electrically connected to the upper side of the control plate 18, and the second fixed trigger member 7 is electrically connected to the lower side of the control plate 18.

[0043] Specifically, in this embodiment, the lower side of the second bent portion 16 is the first trigger portion, and the upper side of the third bent portion 17 is the second trigger portion. The first trigger portion is used to abut against the fixed trigger portion of the first fixed trigger member 6, and the second trigger portion is used to abut against the fixed trigger portion of the second fixed trigger member 7. The control plate 18 is provided with a limiting groove 19 for the third bent portion 17 to pass through, so as to ensure that the movable trigger member 5 moves in the vertical direction. In this embodiment, the second trigger portion abuts against the second fixed trigger member 7 in the initial state. Preferably, the first trigger portion, the second trigger portion, and the fixed trigger portion are arranged perpendicularly to each other, so that when the trigger rod 9 drives the movable trigger member 5 to move, the first trigger portion and the second trigger portion can better abut against the fixed trigger portion.

[0044] The specific working principle of this embodiment is described in detail below:

[0045] In this embodiment, when the suction cup 1 is placed on the plane to be adsorbed, the adsorption surface first comes into contact with the plane to be adsorbed and deforms. As the user presses the suction cup 1 against the plane to be adsorbed, the plane to be adsorbed exerts a reverse pressing force on the trigger button 3, causing the movable trigger 5 to move away from the plane. This causes the second trigger part to disengage from the second fixed trigger 7. At this time, after detecting this disengagement action, the control board 18 generates a corresponding second signal to the air pump, causing the air pump to start working and extract the air between the suction cup 1 and the adsorption surface. As the pressing continues, the movable trigger 5 continues to move and eventually causes the first trigger part to come into contact with the first fixed trigger 6. At this time, after detecting this contact action, the control board 18 generates a corresponding first signal to the air pump, and the air pump shuts down. At this time, the air in the suction cup 1 is completely extracted, and adsorption is completed.

[0046] When the suction cup 1 leaks air, the pressure difference between the inside and outside of the suction cup 1 decreases, thus reducing the pressure exerted by the surface to be adsorbed on the trigger button 3. The movable trigger 5 moves closer to the surface, causing its first trigger part to disengage from the first fixed trigger 6. Upon detecting this disengagement, the control board 18 generates a second signal to the air pump, restarting it to ensure the suction cup 1 maintains strong adsorption capacity. The electrical signal generated by the contact between the movable trigger 5 and the fixed trigger controls the air pump's operation, improving the trigger response speed.

[0047] In this embodiment, if Figure 8 and Figure 9 As shown, the bracket has a first suction port (not shown in the attached figure) protruding outward and communicating with the air chamber 12. The air pump is a piston-type air pump, which achieves air intake and exhaust through the reciprocating motion of the piston in the air pump chamber 24. Specifically, the air pump has a second suction port 20 protruding outward and communicating with the air pump chamber 24, and an exhaust port 21 protruding outward; the first suction port and the second suction port 20 are connected by an air inlet pipe to form an air intake passage; the exhaust port 21 is connected to an exhaust pipe communicating with the external environment to form an exhaust passage. A first one-way valve 22 is provided in the air intake passage, and a second one-way valve 23 is provided in the exhaust passage, so that the gas can only flow unidirectionally from the suction cup 1 through the air inlet pipe to the air pump, and then flow out through the air outlet pipe. By using two one-way valves, the piston in the air pump moves forward to squeeze the gas in the air pump chamber 24, allowing the gas to be smoothly discharged into the external environment through the one-way valves, thus forming a sealed cavity inside the suction cup 1 and achieving a better adsorption effect.

[0048] Furthermore, a pressure relief chamber 25 is provided on the air pump upstream of the first one-way valve 22, which is connected to the air intake passage. A pressure relief valve is provided on the pressure relief chamber 25; the pressure relief valve includes a pressure relief rod, an elastic element 26, and a sealing element 27; a pressure relief port is provided on the pressure relief chamber 25, connecting to the external environment; the pressure relief rod includes a pressure relief part 28 placed inside the pressure relief chamber 25, and an operating part 29 with one end connected to the pressure relief part 28 and the other end protruding outward through the pressure relief port; the elastic element 26 is disposed at the bottom of the pressure relief part 28 and the pressure relief chamber 25, and the sealing element 27 is disposed on the operating part 29, positioned between the pressure relief port and the pressure relief part 28, for sealing the pressure relief port. Under normal conditions, the pressure relief part 28, under the elastic force of the elastic element 26, drives the sealing element 27 to abut against the inner end face of the pressure relief chamber 25 at the pressure relief port, thereby sealing the pressure relief port. The diameter of the pressure relief port is larger than the diameter of the operating part 29. The outer end of the operating part 29 is connected to a button. After the operating part 29 is pressed, the pressure relief part 28 moves the sealing member 27 away from the pressure relief port, so that the pressure relief chamber 25 is connected to the external environment through the pressure relief port, thereby allowing air to enter the suction cup 1, making the air pressure inside the suction cup 1 the same as the external environment, so that the adsorption device 31 can be removed more quickly.

[0049] This utility model also provides a portable mobile lamp, such as Figures 10 to 12 As shown, the device includes a lamp body 30 and the aforementioned adsorption device 31. A first magnetic element is provided at one end of the lamp body 30. A second magnetic element 32, adapted to the first magnetic element, is provided on the adsorption device 31. In this embodiment, the first magnetic element is a magnet, and the second magnetic element 32 is an iron sheet. Of course, in other embodiments, both the first magnetic element and the second magnetic element 32 can be magnets, or one can be a magnet and the other a magnetically attracted metal component.

[0050] In this embodiment, one end of the lamp body 30 has a circular protrusion; the first magnetic member is disposed inside the protrusion; the adsorption device 31 has a circular groove adapted to the protrusion; and the second magnetic member 32 is disposed inside the groove. The circular protrusion and groove allow the lamp body 30 to rotate 360 ​​degrees when the adsorption device 31 is magnetically connected to the lamp body 30.

[0051] In this embodiment, a lamp head 33 is rotatably mounted at the other end of the lamp body 30 along a direction perpendicular to the axis of the boss; the lamp head 33 can rotate 0-270 degrees along its axis. Specifically, as... Figure 11As shown, a notch 34 is provided on the other end of the lamp body 30; a first rotating protrusion 35 is provided on opposite sides of the notch 34, and a second rotating groove 36 adapted to the first rotating protrusion 35 is provided on the lamp head 33, with the rotating protrusion and the rotating groove being dampedly hinged; of course, in other embodiments, a rotating groove may also be provided on opposite sides of the notch 34, and a rotating protrusion adapted to the rotating groove may be provided on the lamp body 30. The adaptation of the rotating protrusion and the rotating groove allows the lamp body 30 to rotate at a certain angle along the rotation axis.

[0052] With the first magnetic component on the lamp body 30, it can be attached to a magnetic object. With the adsorption device 31 and the second magnetic component 32, the lamp body 30 can be attached to a smooth surface of a non-magnetic object, making the lamp suitable for more scenarios.
