Description

Technical Field

[0001] This utility model belongs to the field of lighting technology, specifically relating to an adsorption-type portable lamp. Background Technology

[0002] Portable lights, such as camping lights, maintenance lights, and emergency lights, mostly have hooks or handles that allow users to hang them on external objects such as tree branches, tent poles, and brackets. However, in other application scenarios, such as flat vertical surfaces or ceilings where there is nowhere to hang them, like glass, tiles, metal cabinets, or smooth plastic surfaces, the above-mentioned hanging lights cannot be used.

[0003] Common adsorption-type lamps usually integrate magnets, allowing the lamps to adhere to ferrous metal surfaces. However, after continuous use, the LED light source and driver circuit inside the lamp will generate heat. This heat will be directly conducted to the magnet components in contact with the housing. Once the magnet temperature rises to its operating critical point, the adsorption force will decrease significantly, eventually causing the lamp to slip off the adsorption surface and break.

[0004] Therefore, a portable lamp was designed that can adapt to various smooth surfaces and maintain a stable and reliable adsorption force over a long period of time while the lamp is in continuous operation. Utility Model Content

[0005] The purpose of this invention is to provide an adsorption-type portable lamp to solve the problems mentioned in the background art.

[0027] Example 1

[0028] like Figures 1 to 6 The portable suction lamp shown includes a housing 1, a mounting groove 2 on the rear side of the housing 1, a fixing cylinder 3 in the middle of the mounting groove 2, mounting holes 4 on the mounting groove 2 located outside the fixing cylinder 3, a suction cup 5 sliding between the mounting holes 4, a fixing plate 6 installed between the front sides of the mounting holes 4, an outer cover 601 inserted into the outside of the fixing plate 6, a working groove 8 recessed at the bottom of the housing 1, an LED light bead board 9 inside the working groove 8, and an indicator light 10, a charging port 11, a human infrared sensor 12, and a start button 13 arranged from left to right on the front side of the housing 1; a vacuum pump 18 is located at the bottom inside the housing 1, the output end of the vacuum pump 18 is connected to a first air pipe 19, the first air pipe 19 is connected to the suction cup 5 via the fixing cylinder 3; the front side of the housing 1 is provided with... The housing 1 has a guide rim 14 located above the indicator light 10, charging port 11, human infrared sensor 12, and start button 13. A PCB circuit board 15 is installed inside the housing 1, connected to the rear of the indicator light 10, charging port 11, human infrared sensor 12, and start button 13. A pneumatic control valve 20 is provided on the PCB circuit board 15, connected to a second air pipe 22, which communicates with the suction cup 5 via a mounting groove 2. A mounting plate 16 is provided on the rear inner wall of the housing 1, on which a battery 17 is installed. A solar panel 7 is rotatably mounted on the rear top of the housing 1. A guide sticker 23 extends from the edge of the suction cup 5, and a recycling groove 24 is recessed at the rear of the housing 1 on one side of the guide sticker 23.

[0029] This invention utilizes a vacuum suction cup structure to firmly adhere to non-hooked, non-magnetic surfaces such as glass, ceramic tiles, metal, and plastic, making it suitable for various smooth surfaces and offering greater adaptability. The invention employs a vacuum pump 18, a pressure control valve 20, and a vacuum sensor working in tandem to monitor and automatically replenish the vacuum in real time, preventing the lamp from falling off due to minor leaks and ensuring continuous and stable operation. This invention supports dual-mode lighting control: manual control or automatic lighting upon approach and delayed shutdown upon leaving, achieved via a human infrared sensor 12, resulting in intelligent energy saving. This invention features a dual power supply system: a lithium battery 17 provides the main power and supports USB charging, while a solar panel 7 assists with trickle charging, ensuring long-lasting power supply.

[0030] Example 2

[0031] like Figures 1 to 2 The illustrated portable suction lamp includes a housing 1 with a mounting groove 2 recessed into the rear of the housing 1. When a suction cup 5 is installed in the mounting groove 2, the deflatable suction cup 5 can be embedded and stored within the mounting groove 2 for easy storage and transportation. A fixing cylinder 3 is located in the middle of the mounting groove 2. The fixing cylinder 3 is hollow and connects the vacuum pump 18 inside the housing 1 to the suction cup 5, enabling inflation and deflation of the suction cup 5. Four mounting holes 4 are located on the outside of the fixing cylinder 3 in the mounting groove 2. The suction cup 5 is slidably installed between the mounting holes 4. After the suction cup 5 is installed between the mounting holes 4, a fixing plate 6 can be placed to limit the suction cup 5. The fixing plate 6 also has corresponding holes. By inserting a nut between the nut and the mounting holes 4, the fixing plate 6 can indirectly limit the suction cup 5, facilitating later disassembly and replacement, and avoiding direct fixing of the suction cup 5, which could damage the suction cup 5 and cause it to lose its suction function.

[0032] Additionally, a guide sticker 23 extends from the edge of the suction cup 5. When the suction cup 5 stops adsorbing and cannot detach from the platform for a short time, the staff can use the guide sticker 23 to pry the suction cup 5 and the entire lamp to detach them, thus achieving quick disassembly. A recycling groove 24 is recessed at the rear of the outer shell 1 on one side of the guide sticker 23. When the suction cup 5 is embedded in the mounting groove 2, the guide sticker 23 is placed so that the surface of the outer cover 601 is flush with the rear side of the outer shell 1.

[0033] An outer cover 601 is inserted into the outside of the fixing plate 6 to cover the above-mentioned components, prevent dust and moisture from entering the internal structure, and make the overall appearance of the lamp more concise and beautiful.

[0034] Example 3

[0035] like Figures 1 to 6The portable lamp shown has an indicator light 10, a charging port 11, a human infrared sensor 12 and a start button 13 arranged from left to right on the front side of the outer shell 1. Inside the outer shell 1, on the rear side of the above-mentioned components, there is a PCB circuit board 15, which is used to receive and control the operation commands of the above components.

[0036] First, a vacuum pump 18 is installed at the bottom of the outer casing 1. The output end of the vacuum pump 18 is connected to a first air pipe 19. The first air pipe 19 is connected to the suction cup 5 through the fixed cylinder 3, forming a vacuum generation path. A pressure control valve 20 is integrated on the PCB circuit board 15. The pressure control valve 20 is connected to the internal cavity of the suction cup 5 through the second air pipe 22 and the mounting groove 2, forming a vacuum control and monitoring path. Then, when the vacuum pump 18 starts synchronously and draws out the air in the suction cup 5 through the first air pipe 19, the internal pressure drops rapidly. During this process, the vacuum sensor (integrated on the PCB board together with the pressure control valve 20) monitors the pressure change in the suction cup 5 in real time. Once the pressure reaches the preset "adsorption success" threshold, the vacuum sensor sends a signal, and the main controller immediately instructs the vacuum pump 18 to stop working and immediately closes the pressure control valve 20, directly cutting off the connection between the suction cup 5 and the external environment, "locking" the vacuum state in the suction cup 5, and finally achieving a firm adsorption between the suction cup 5 and the mounting surface.

[0037] During continuous adsorption, the vacuum sensor continuously monitors the system. If a slight leak occurs in the suction cup 5, causing the pressure to exceed the minimum set value for "maintaining adsorption", the system will automatically restart the vacuum pump 18 and open the pressure control valve 20 to perform supplementary pumping until the pressure is restored, ensuring that the lamp is stable and reliable throughout its use.

[0038] When it is necessary to disassemble the lamp, the user can issue a command by pressing and holding the start button 13. The air pressure control valve 20 switches to the air release state, allowing external air to quickly enter the suction cup 5, balancing the internal and external pressures. The suction force disappears instantly, making it easy to remove the lamp.

[0039] Secondly, the bottom of the outer casing 1 is recessed with a working groove 8, and the working groove 8 contains an LED lamp board 9. The LED lamp board 9 has a dual trigger mode of manual and automatic. In manual mode, the start button 13 is pressed to control the LED lamp in a cycle. The first press turns on the LED lamp at full power, providing maximum lighting brightness; the second press turns on the LED lamp at half power, switching to energy-saving mode, reducing energy consumption while ensuring basic lighting; the third press turns off all parts of the lamp, including lighting, vacuum adsorption and sensor monitoring functions, and enters standby mode.

[0040] In automatic mode, when the lamp is on, the human infrared sensor 12 installed on the front of the housing 1 monitors the lamp. When someone passes by, the sensor detects human movement in the preset area below and immediately drives the LED lamp board 9 through the controller to automatically light up according to the currently set power level (full power or half power). After the preset delay is reached when no one passes through the target area, the controller automatically cuts off the power to the LED lamp board 9, and the lamp enters the standby power-saving state. However, the vacuum adsorption system and the sensor itself continue to work, waiting for the next trigger.

[0041] Next, a mounting plate 16 is provided on the rear side of the inner wall of the outer casing 1. A 3.7V, 2000mAh 18650 lithium battery 17 is installed on the mounting plate 16. The battery 17 is used to supply power to the above-mentioned electrical components. During normal use, the battery 17 is charged through the charging port 11 on the front side of the outer casing 1. During the operation of the lamp, when the battery 17 has not reached the minimum set power value, the indicator light 10 flashes red. When charging, the indicator light 10 is always red, and the light turns off when fully charged. In addition, a 70mm x 39.5mm, 5.5V 60mA solar panel 7 is rotatably installed on the rear top of the outer casing 1. During the day, the solar panel 7 can convert light energy into electrical energy to trickle charge the internal battery 17. In actual use, the user can manually rotate the solar panel 7 to the optimal light angle to maximize energy collection efficiency.

[0042] Furthermore, a guide ridge 14 is provided on the front side of the housing 1 at the top of the indicator light 10, charging port 11, human infrared sensor 12 and start button 13; it is used to block dust, water droplets or slight liquid splashes falling vertically, protect the key interfaces and sensors below from contamination or corrosion, ensure good contact of the charging interface, prevent scratches on the human infrared sensor 12, and extend the lifespan of the button; at the same time, the protruding guide ridge 14 can also reduce the probability of the start button 13 being accidentally triggered by an impact.

[0043] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
