Description

Technical Field

[0001] The invention relates to the field of flashlights, in particular to a waterproof floodlight capable of reducing battery aging, and also to a handheld illumination lamp. Background Art

[0002] A flashlight is a common handheld electronic lighting tool. When it is needed in scenarios with high requirements for lighting brightness, a high-power flashlight is mostly needed. However, the greater the power of the flashlight, the more heat the light source emits, thereby accelerating the aging of the rechargeable battery. Its voltage output may become unstable, affecting the brightness and lighting effect of the flashlight, causing it to flicker or suddenly go out. Although some existing high-power flashlights use built-in cooling fans to optimize the heat dissipation effect, the cooling fan wiring is complicated and the assembly is cumbersome. When the cooling fan ages or fails, it is difficult to quickly replace and repair the cooling fan.

[0003] The currently disclosed Chinese patent CN217785085U discloses a flashlight heat dissipation structure and a flashlight, including a lamp head assembly, a radiator composed of a plurality of heat sinks, and a mounting seat, one end of the mounting seat is connected to the lamp head assembly, and the other end is used to connect to the flashlight body, a heat dissipation bin is formed between the lamp head assembly and the mounting seat, the radiator is located in the heat dissipation bin, a circuit board is provided in the mounting seat, a first conductive seat electrically connected to the circuit board is provided on the side of the mounting seat, an open end of the heat dissipation bin is close to the first conductive seat, a heat dissipation bin cover is detachably connected to the open end of the heat dissipation bin, one end of the heat dissipation bin cover is connected to a fan that can be accommodated in the heat dissipation bin, and the other end is provided with a second conductive seat electrically connected to the first conductive seat, and the second conductive seat is electrically connected to the fan.

[0004] The above patent sets a fan bracket, which is detachably connected to the heat dissipation bin cover, so as to facilitate the removal of the fan from the heat dissipation bin cover, and sets a plurality of heat dissipation ports on the side wall of the heat dissipation bin, so as to facilitate air convection exchange with the external environment and improve the heat dissipation effect. Although the heat dissipation port design of the heat dissipation bin is conducive to air circulation, it also provides a channel for the entry of dust and tiny particles. When not in use or in use, air will circulate, causing dust to accumulate therein, affecting the heat dissipation efficiency during use, and often requiring cleaning and maintenance. Therefore, there is a need for a waterproof floodlight that can dissipate heat for rechargeable batteries, reduce aging of rechargeable batteries, and reduce dust accumulation.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] See also Figure 1-Figure 8 As shown, a waterproof floodlight for reducing battery aging comprises a lamp holder 1, a rechargeable battery 2, a barrel 3 and a heat dissipation structure, wherein the barrel 3 is provided with a conductive chamber 4 for placing the rechargeable battery 2, the heat dissipation structure is arranged between the conductive chamber 4 and the barrel 3, the heat dissipation structure has a heat dissipation fan 5 arranged between the conductive chamber 4 and the lamp holder 1, a heat dissipation gap 31 is left between the barrel 3 and the conductive chamber 4, an air inlet 32 ​​is provided in the area of ​​the barrel 3 surrounding the heat dissipation fan 5, an air outlet 33 is provided in the area of ​​the barrel 3 surrounding the conductive chamber 4, a dustproof structure is provided on the barrel 3, and the dustproof structure has a dust filter arranged at the air inlet 32. A filter element 321 and a shielding element 331 are arranged at the air outlet 33. When the flashlight is used, the user operates the shielding element 331 to open the air outlet 33 so that the heat generated by the rechargeable battery 2 can be dissipated from the air outlet 33. Conversely, when the flashlight is not in use, the user operates the shielding element 331 to close the air outlet 33 so that external dust cannot adhere to the conductive chamber body 4 through the air outlet 33. The front end of the barrel 3 is provided with the lamp holder 1, and the rear end of the barrel 3 is provided with a screw cap 6 to ensure that the rechargeable battery 2 is stably pressed against the conductive chamber body 4. A sealing gasket 61 that presses against the surface of the screw cap 6 is fixed between the barrel 3 and the conductive chamber body 4.

[0033] The end of the conductive chamber 4 for the rechargeable battery 2 to extend into has a positive contact 21, and the screw cover 6 has a negative contact 22. The screw cover 6 has a charging port, which is not shown in the figure. When the rechargeable battery 2 is placed in the conductive chamber 4 and the screw cover 6 is tightened on the barrel 3, the two ends of the rechargeable battery 2 are respectively in contact with the positive contact 21 and the negative contact 22, so that the opening and closing of the lamp holder 1 can be controlled. The sealing gasket 61 between the barrel 3 and the conductive chamber 4 has a waterproof effect to prevent water from entering the conductive chamber 4 and causing the rechargeable battery 2 to fail. Since the rechargeable battery 2 is placed in the conductive chamber 4, even if water enters between the barrel 3 and the conductive chamber 4 through the air inlet 32 ​​or the air outlet 33, it cannot interfere with the rechargeable battery 2, thereby achieving the waterproof effect of the flashlight.

[0034] Before use, first ensure that the rechargeable battery 2 of the flashlight is fully charged, unscrew the screw cap 6 at the tail end of the barrel 3, check whether the rechargeable battery 2 is correctly placed in the conductive compartment 4, and ensure that the positive electrode of the rechargeable battery 2 is in contact with the positive contact 21 in the conductive compartment 4, and the negative electrode is in contact with the negative contact 22 on the screw cap 6, tighten the screw cap 6, and ensure that the sealing gasket 61 on the screw cap 6 is in close contact with the barrel 3 to ensure the waterproof performance of the flashlight. When turning on the flashlight, operate the power switch on the flashlight, and the lamp head 1 starts to emit light. At this time, the brightness and light distribution of the lamp head 1 will be optimized through design to ensure uniform lighting effects and suitable for lighting needs in various occasions. During long-term use of the flashlight, the rechargeable battery 2 will gradually heat up, and the cooling fan 5 in the heat dissipation structure will turn on with the lamp head 1 After operation, the heat emitted by the rechargeable battery 2 can be discharged from the conductive chamber 4, and the air inlet 32 ​​around the barrel 3 introduces external cold air to cool the conductive chamber 4 and the surface of the rechargeable battery 2. Since a filter 321 is provided at the air inlet 32 ​​of the barrel 3, dust is blocked outside, and clean cold air can be sucked into it through the filter 321, and hot air is discharged through the air outlet 33, thereby effectively reducing the temperature of the rechargeable battery 2 and preventing overheating. In order to prevent dust from entering the conductive chamber 4, the user can manually close the shielding member 331 located at the air outlet 33 of the barrel 3 when the flashlight is not in use. This operation ensures that external dust will not enter the inside of the barrel 3 when the flashlight is stored or carried, thereby keeping the conductive chamber 4 and the rechargeable battery 2 clean.

[0035] See also Figure 2-Figure 9As shown, the heat dissipation structure also has a heat-conducting layer 7 arranged around the conductive chamber body 4, the heat-conducting layer 7 is sleeved on the conductive chamber body 4, both ends of the heat-conducting layer 7 have rubber rings 71 in contact with the heat-conducting layer 7, a plurality of heat-dissipating holes 41 are opened on the surface of the conductive chamber body 4, and a conduction gap 42 is reserved between the conductive chamber body 4 and the heat-conducting layer 7 for the heat generated by the rechargeable battery 2 to be fully dispersed on the heat-conducting layer 7 through the heat-dissipating holes 41, and the heat-dissipating gap 31 is formed between the heat-conducting layer 7 and the barrel 3.

[0036] The heat-conducting layer 7 is specifically a heat-conducting sleeve, which is tightly wrapped around the outside of the conductive chamber 4. The two ends are sealed with the conductive chamber 4 by rubber rings 71, which not only ensures the tight combination with the conductive chamber 4, but also prevents the penetration of moisture and particles. In addition, a plurality of heat dissipation holes 41 on the surface of the conductive chamber 4 constitute a channel for heat transfer to the heat-conducting layer 7, so that the heat energy generated by the rechargeable battery 2 during operation can quickly penetrate the conductive chamber 4 and enter the heat-conducting layer 7. The conduction gap 42 between the conductive chamber 4 and the heat-conducting layer 7 not only reserves sufficient space for heat circulation, but also promotes the uniform distribution of heat on the surface of the heat-conducting layer 7. The heat is evenly distributed rather than locally accumulated, thereby accelerating the transfer process of heat from the rechargeable battery 2 to the external environment. The heat dissipation gap 31 formed by the thermal conductive layer 7 and the barrel 3 further optimizes the heat exchange efficiency, just like a miniature air duct. Together with the built-in cooling fan 5 of the flashlight, it promotes the continuous influx of external cold air and exchanges heat energy with the surface of the thermal conductive layer 7. Subsequently, the hot air is discharged through the air outlet 33 of the barrel 3, forming an efficient natural convection cycle, which not only greatly improves the heat dissipation efficiency, but also ensures that the rechargeable battery 2 is maintained within a suitable operating temperature range, reducing the risk of performance degradation and life reduction due to high temperature.

[0037] See also Figure 2-Figure 9 As shown, the end of the barrel 3 has a ring sleeve 611 for fixing the sealing gasket 61, and a guide groove for allowing the heat-conducting layer 7 to be drawn out from the barrel 3 is reserved between the ring sleeve 611 and the sealing gasket 61 and the conductive chamber 4. The end of the conductive chamber 4 extending into the barrel 3 has a step 43 for the end of the heat-conducting layer 7 to abut against. When the screw cap 6 is tightened on the barrel 3, the heat-conducting layer 7 is confined between the screw cap 6 and the step 43, so that the heat-conducting layer 7 remains in a stable state in the barrel 3.

[0038] The preset guide groove between the sealing gasket 61 on the ring sleeve 611 and the conductive chamber body 4 not only ensures a close fit between the sealing gasket 61 and the heat-conducting layer 7 to prevent moisture penetration, but also provides a smooth path for the disassembly and assembly of the heat-conducting layer 7, which means that when the heat-conducting layer 7 needs to be cleaned or replaced, the user can easily pull the heat-conducting layer 7 out of the barrel 3 through the guide groove, which greatly simplifies the maintenance process and improves the user experience. The conductive chamber body 4 extends into the step 43 at one end of the barrel 3 that precisely matches the end of the heat-conducting layer 7, so that when the screw cap 6 is firmly tightened on the barrel 3, the heat-conducting layer 7 is firmly clamped between the screw cap 6 and the step 43 of the conductive chamber body 4, ensuring the fixity of the heat-conducting layer 7. Even if the flashlight is subjected to impact or vibration, the heat-conducting layer 7 can maintain its proper position and continue to effectively conduct heat.

[0039] See also Figure 3 and Figure 5 As shown, a fixed magnet 431 is provided at the step 43 of the conductive chamber body 4, and a movable magnet 432 capable of fitting with the fixed magnet 431 is provided at the end of the heat-conducting layer 7 extending into the cylinder body 3. When the fixed magnet 431 and the movable magnet 432 are adsorbed together, the heat-conducting layer 7 is fixed. Conversely, when the heat-conducting layer 7 is pulled out of the cylinder body 3, the user only needs to apply force to the heat-conducting layer 7 to separate the movable magnet 432 from the fixed magnet 431.

[0040] When assembling the flashlight, the heat-conducting layer 7 is inserted into the barrel 3, and the movable magnet 432 automatically fits with the fixed magnet 431 without the need for additional fasteners or complicated operations. The two are tightly combined by magnetic force, thereby achieving a stable positioning of the heat-conducting layer 7. Considering that the heat-conducting layer 7 may need to be inspected or replaced regularly to ensure the best heat dissipation effect, the user only needs to gently pull the heat-conducting layer 7 outward to overcome the attraction between the fixed magnet 431 and the movable magnet 432, and the movable magnet 432 will slowly break away from the adsorption of the fixed magnet 431, so that the heat-conducting layer 7 can be smoothly pulled out of the barrel 3. This process is simple and fast, and the maintenance difficulty is greatly reduced. The magnetic attraction fixing method ensures easy disassembly and assembly without sacrificing the sealing performance between the conductive chamber 4. The tight fit between the movable magnet 432 and the fixed magnet 431, combined with the design of the original rubber ring 71, together constitutes multiple protections, effectively blocking the invasion of external moisture and impurities, and ensuring the safety of the rechargeable battery 2 inside the flashlight.

[0041] See also Figure 3 and Figure 5As shown, a holder 62 is provided on the end of the conductive housing 4 extending into the barrel 3 and the screw cap 6, respectively. Each of the holders 62 is provided with a slot for the corresponding end of the rechargeable battery 2 to be inserted therein and ensure that the rechargeable battery 2 is coaxial with the conductive housing 4. The inner diameter of the conductive housing 4 is larger than the diameter of the rechargeable battery 2, and the area between the rechargeable battery 2 and the heat-conducting layer 7 through all the heat dissipation holes 41 together form the conductive gap 42.

[0042] When the rechargeable battery 2 is placed in the conductive housing 4 and the screw cap 6 is tightened, the two ends of the rechargeable battery 2 will fit into the corresponding slots of the socket 62, thereby achieving accurate positioning and firm fixation of the rechargeable battery 2 in the conductive housing 4, ensuring the coaxial alignment of the rechargeable battery 2 and the conductive housing 4, improving the stability of the connection of the rechargeable battery 2, and reducing the poor contact problem caused by the loosening of the rechargeable battery 2. The inner diameter of the conductive housing 4 is designed to be slightly larger than the diameter of the rechargeable battery 2, creating an annular space around the rechargeable battery 2. This space works together with all the heat dissipation holes 41 to form a wide conductive gap 42. When the rechargeable battery 2 generates heat during use, the heat can be quickly transferred to the heat conductive layer 7 through the conductive gap 42. The layout of the heat dissipation holes 41 ensures that the heat can be evenly distributed on the entire surface of the heat conductive layer 7, not just the part close to the rechargeable battery 2, thereby significantly enhancing the efficiency of heat exchange.

[0043] See also Figure 3 , Figure 5 and Figure 6 As shown, a plurality of guide bars 44 are evenly distributed around the conductive housing 4, and a guide channel for guiding the placement of the rechargeable battery 2 is formed between the plurality of guide bars 44.

[0044] When the user needs to install the rechargeable battery 2, he only needs to align one end of the rechargeable battery 2 with the entrance of the conductive compartment 4 and gently push it in along the guide channel. The rechargeable battery 2 can automatically align with the central axis under the guidance of all the guide bars 44 and slide smoothly into the predetermined position. The user does not need to perform additional alignment operations, which greatly simplifies the installation process, reduces the possibility of incorrect insertion, and effectively avoids lateral squeezing or scratching that the rechargeable battery 2 may suffer during the insertion process.

[0045] See also Figure 2-Figure 4 As shown, the filter element 321 is specifically a filter screen arranged around the area of ​​all air inlets 32 on the barrel body 3, and the blowing direction of the cooling fan 5 is from the air inlet 32 ​​to the air outlet 33.

[0046] When the cooling fan 5 is started and begins to work, firstly, with the help of the driving force of the cooling fan 5, air is actively sucked into the air inlet 32. At the moment when the air passes through the filter 321, the filter 321 plays its filtering role, and larger particles are blocked outside, allowing only clean air to continue to flow inside. This process ensures the quality of air entering the barrel 3, and avoids dust adhering to the surface of the thermal conductive layer 7 and affecting the heat dissipation effect. The blowing direction of the cooling fan 5 is a straight path from the air inlet 32 ​​to the air outlet 33, which means that after the airflow is filtered by the filter 321, it will flow quickly and directionally along the preset air duct to the area where heat dissipation is required, which is conducive to forming an efficient airflow circulation and quickly taking away heat.

[0047] See also Figure 4 , Figure 8 and Fig. 9 As shown, the air outlet 33 on the barrel body 3 is specifically a strip-shaped opening opened along the axial direction of the barrel body 3, and the barrel body 3 is provided with a plurality of the air outlets 33 around its circumferential direction, and each air outlet 33 is provided with a shielding member 331, and one end of the shielding member 331 close to the air outlet 33 is fixedly connected to the barrel body 3, and the other end of the shielding member 331 extends along the axial direction of the barrel body 3 toward the direction of the screw cap 6, and the screw cap 6 is provided with a driving member 332 which can simultaneously drive all the shielding members 331 to tilt in the direction away from the barrel body 3.

[0048] The shielding member 331 is specifically an elastic strip that can shield the air outlet 33, and the driving member 332 is specifically a ring threadedly connected to the rotary cover 6. The rotary cover 6 has an outer ring 63 on which the ring sleeve 611 is arranged, and the inner side of the outer ring 63 has an internal thread that can be threadedly connected to the ring sleeve 611, and the outer side of the outer ring 63 has an external thread that can be threadedly connected to the ring sleeve, and the ring sleeve 611 and the ring have threaded portions that are threadedly connected to the outer ring 63 respectively. The end of the ring facing the shielding member 331 has a slope 3321 that is close to the outer surface of the barrel 3, and all the ends of the shielding members 331 facing the slope 3321 are bent outwards. When the user manually rotates When the ring is rotated, the ring moves toward the shielding piece 331 until the landslide 3321 on the ring enters between the barrel 3 and all the shielding pieces 331. As the ring continues to move, all the shielding pieces 331 are tilted outward with their ends fixed to the barrel 3 as fulcrums. At this time, the shielding piece 331 is away from the surface of the barrel 3, and the air outlet 33 on the barrel 3 is opened. When the flashlight is subsequently started, the heat emitted by the rechargeable battery 2 can be dissipated from the air outlet 33, thereby achieving the effect of heat dissipation of the rechargeable battery 2. When the flashlight is not suitable, the ring only needs to be rotated back to its original position so that all the shielding pieces 331 are re-fitted with the barrel 3, thereby closing the air outlet 33 to prevent dust from entering.

[0049] See also Figure 2 and Figure 3 As shown, a sealing baffle 11 is fixedly provided in the barrel body 3 and between the lamp holder 1 and the conductive chamber body 4. The sealing baffle 11 is used to prevent water from entering the barrel body 3 and causing damage to the internal circuit of the lamp holder 1. The end of the conductive chamber body 4 extending deep into the barrel body 3 has a detachable extension shaft 111 connected to the sealing baffle 11. The cooling fan 5 has a sleeve 51 rotatably mounted on the extension shaft 111, and a bearing 52 is connected between the sleeve 51 and the extension shaft 111.

[0050] The extension shaft 111 is threadedly connected to the sealing baffle 11. When the lamp holder 1 is started, the cooling fan 5 rotates automatically. Conversely, when the lamp holder 1 is turned off, the cooling fan 5 stops rotating. When the cooling fan 5 needs to be cleaned, it is only necessary to rotate the conductive chamber body 4 so that the extension shaft 111 falls off the sealing baffle 11, thereby taking the cooling fan 5 out of the barrel body 3 together, which facilitates cleaning.

[0051] See also Fig.10 As shown, a handheld illumination lamp includes a handheld handle 8 fixedly mounted on a barrel 3, wherein the handheld handle 8 is provided with an opening to avoid all shielding members 331, and also includes a waterproof floodlight that reduces battery aging.

[0052] The hand-held handle 8 is convenient for hand-holding and does not affect the operation of the shielding member 331 , thereby improving the comfort of use.

[0053] The present invention combines heat dissipation and dust prevention functions, and effectively solves the problems of overheating and dust intrusion of the rechargeable battery 2 that are common in high-intensity use of the flashlight. By providing a heat dissipation fan 5 and a heat dissipation gap 31, the temperature of the rechargeable battery 2 can be effectively controlled, and the situation in which overheating causes aging of the rechargeable battery 2 is reduced. In addition, the filter 321 at the air inlet 32 ​​on the barrel 3 and the shielding member 331 at the air outlet 33 on the barrel 3 can prevent external dust from entering the barrel 3 regardless of whether the user uses the flashlight, further protecting the rechargeable battery 2, improving the heat dissipation effect of the rechargeable battery 2, providing the user with a stable and reliable lighting experience, and effectively extending the service life of the rechargeable battery 2, reducing failures caused by environmental factors.

[0054] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
