Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.
[0039] The present invention provides a waterproof structure and a flashlight, such as Figures 1 to 6As shown, the present invention solves the problem in the prior art that water enters the flashlight, causing the flashlight to be damaged and unusable. Specifically, the waterproof structure 10 includes a shell 100 and a waterproof component 200. A light-emitting circuit component 300 is provided in the shell 100 component. The light-emitting circuit component 300 generates light, so that the flashlight can illuminate the external environment through the light. In order to enable the flashlight to continue to emit light by charging the flashlight, the shell 100 is provided with a charging port 110. The charging port 110 is connected to the light-emitting circuit component 300. The flashlight is connected to an external power supply device through the charging port 110. The power supply device supplies power to the flashlight. The flashlight is gradually charged in the process to store electrical energy, and the electrical energy stored in the flashlight can enable the flashlight to continue to emit light. When the flashlight is charged, in order to prevent water from entering the inside of the flashlight from the charging port 110, a waterproof component 200 is provided at this time. The waterproof component 200 can be detachably installed in the charging port 110. When it is necessary to connect an external power supply device through the charging port 110, the waterproof component 200 is removed from the charging port 110 to expose the charging port 110 so that the charging port 110 can be connected to the external power supply device, allowing the power supply device to supply power to the flashlight. When the charging port 110 is used, the waterproof component 200 is installed on the charging port 110 to seal the charging port 110 to prevent water from entering the flashlight through the charging port 110, thereby ensuring that the flashlight can be used stably.
[0040] Furthermore, to seal the charging port 110 through the waterproof assembly 200, the waterproof assembly 200 includes a protective sleeve 210 and a waterproof cover 220. The protective sleeve 210 and waterproof cover 220 cooperate to seal the charging port 110, preventing water from entering the interior of the flashlight through the charging port 110. The protective sleeve 210 is installed within the charging port 110 and fits over the outer ring of the power supply port 310 of the light-emitting circuit assembly 300. This protects the power supply port 310, preventing water from flowing from the outer ring into the power supply port 310 and preventing the outer ring of the power supply port 310 from contacting other structures, which could cause the power supply port 310 to be squeezed and damaged by other structures. Only the front end of the power supply port 310 is allowed to connect to an external power supply device, while the sides of the power supply port 310 are completely covered by the protective sleeve 210. The waterproof cover 220 is inserted into the end of the protective cover 210 away from the light-emitting circuit assembly 300 to block the protective cover 210. By blocking the protective cover 210, the front end of the power supply port 310 is also blocked. In this way, the power supply port 310 is completely wrapped by the waterproof cover 220 and the protective cover 210 to prevent water from entering the power supply port 310. Only when it is necessary to supply power to the light-emitting circuit assembly 300 through the power supply port 310, the waterproof cover 220 is removed from the protective cover 210 to expose the front end of the power supply port 310, so that the power supply port 310 is convenient for connecting to an external power supply device.
[0041] When the protective cover 210 is installed in the charging port 110, to prevent the protective cover 210 from shaking inside the charging port 110 and affecting the waterproof effect, the relative movement between the protective cover 210 and the charging port 110 needs to be restricted. The protective cover 210 can only be removed from the charging port 110 by applying a certain amount of force. Therefore, the outer ring of the protective cover 210 is provided with a sealing groove 211. The waterproof assembly 200 also includes a sealing ring 230, which is mounted on the sealing groove 211. The sealing groove 211 allows the sealing ring 230 to be better mounted on the protective cover 210 and prevents the sealing ring 230 from falling off the protective cover 210. When the protective cover 210 is installed in the charging port 110, the sealing ring 230 fills the gap between the protective cover 210 and the charging port 110, increasing the friction between the protective cover 210 and the charging port 110, thereby making it more difficult for the protective cover 210 to move relative to the charging port 110. Specifically, when the protective cover 210 is installed in the sealing port 214, the sealing ring 230 is squeezed by the force during the installation process. When the protective cover 210 is installed in the appropriate position, the sealing ring 230 is no longer affected by the external force and gradually restores its shape. While restoring its shape, it begins to fill the gap between the protective cover 210 and the charging port 110, thereby limiting the relative movement between the protective cover 210 and the charging port 110.
[0042] Furthermore, when the protective cover 210 is installed on the charging port 110, to achieve optimal protection, the front end of the protective cover 210 extends into the housing 100 and fits over the outer ring of the power port 310. A sealing groove 211 is defined in the middle outer ring of the protective cover 210, and a sealing ring 230 fits over the sealing groove 211, restricting relative movement between the protective cover 210 and the charging port 110. The rear end of the protective cover 210 mates with the side of the charging port 110 facing away from the inner wall of the housing 100, preventing water from flowing through the gap between the protective cover 210 and the charging port 110. To further enhance the waterproofing effectiveness of the waterproof assembly 200, it is necessary to ensure that the rear end of the protective cover 210 closely mates with the side of the charging port 110 facing away from the inner wall of the housing 100. Therefore, the outer ring of the protective cover 210 is further provided with a first mate edge 212, which mates with the second mate edge 111 of the charging port 110 to enhance the waterproofing effectiveness. Therefore, in the present application, in order to achieve a tight fit between the first fitting edge 212 and the second fitting edge 111, the first fitting edge 212 and the second fitting edge 111 are connected together through an ultrasonic process to achieve a waterproof effect and prevent water from flowing into the first fitting edge 212 and the second fitting edge 111 and entering the charging port 110. The ultrasonic process is an existing technology and is therefore not described in detail here.
[0043] like Figure 2As shown, the protective cover 210 includes a connection port 213 and a sealing port 214. Because the power supply port 310 of the light-emitting circuit assembly 300 is elliptical, the connection port 213 is also elliptical. The connection port 213 is sleeved on the outer ring of the power supply port 310, and the connection port 213 and the power supply port 310 have an interference fit to prevent the protective cover 210 from falling off the power supply port 310, thereby achieving the protective cover 210 wrapping the side of the power supply port 310. The sealing port 214 is set on the side of the protective cover 210 away from the power supply port 310. At this time, the power supply port 310 is sealed by inserting the waterproof cover 220 into the sealing port 214, thereby achieving a waterproof effect. Specifically, a blocking plug 221 is provided on the side of the waterproof cover 220 facing the protective cover 210. In the present application, the sealing port 214 is also elliptical, but the sealing port 214 is smaller than the connecting port 213. At this time, the sealing port 214 only corresponds to the opening of the power supply port 310. Therefore, when the sealing port 214 is not blocked, the external power supply device can just pass through the sealing port 214 to connect with the power supply port 310. Correspondingly, the blocking plug 221 is also elliptical in shape, and its size is the same as that of the sealing opening 214. When the sealing opening 214 needs to be sealed to prevent water from entering the flashlight, the blocking plug 221 is inserted into the sealing opening 214, thereby achieving the sealing of the protective cover 210 by the waterproof cover 220. The blocking plug 221 and the sealing opening 214 have an interference fit, thereby preventing the blocking plug 221 from falling out of the sealing opening 214 after passing through the sealing opening 214. The blocking plug 221 can only be pulled out of the sealing opening by applying a certain force. In addition, a filling ring 2211 is also sleeved on the blocking plug 221, which has the same function as the sealing ring 230. The filling ring 2211 fills the gap between the blocking plug 221 and the sealing opening 214, further increasing the friction between the blocking plug 221 and the sealing opening 214, thereby preventing the blocking plug 221 from falling out of the sealing opening 214.
[0044] In the present application, the waterproof cover 220 is detachably mounted on the charging port 110 to prevent water from entering the flashlight through the charging port 110, thereby achieving a waterproof effect. When the flashlight needs to be charged to replenish the power to maintain the operation of the flashlight, the waterproof cover 220 needs to be removed from the charging port 110 so that the power supply port 310 can be exposed and connected to the external power supply device. If the removed waterproof cover 220 is placed at random in other locations without being specially stored, there is a risk of the waterproof cover 220 being lost when the flashlight is used for charging for a long time due to the random placement of the waterproof cover 220. Without the waterproof cover 220, the flashlight no longer has a waterproof effect, which greatly reduces the scope of use of the flashlight. Therefore, in order to prevent the waterproof cover 220 from being lost, and to better detachably mount the waterproof cover 220 on the charging port 110, the waterproof cover 220 also includes a stopper 222, which is arranged next to the blocking plug 221. The shell 100 is also provided with a fixing port 120, which is arranged next to the charging port 110. The limit plug 222 is inserted into the fixing port 120 to limit the movement range of the waterproof cover 220, and then the waterproof cover 220 is kept on the shell 100 through the cooperation of the limit plug 222 and the fixing port 120. Even if the power supply port 310 is needed to charge the flashlight and the waterproof cover 220 is removed from the protective cover 210, the waterproof cover 220 can still be kept on the shell 100, avoiding the waterproof cover 220 from being lost due to being placed in other positions, and the movement range of the waterproof cover 220 can also be limited by the limit plug 222 and the fixing port 120. When the flashlight has finished charging and the charging port 110 needs to be sealed to prevent water from entering the flashlight through the charging port 110, the waterproof cover 220 needs to be installed in the protective cover 210. Pull the waterproof cover 220 in the direction gradually approaching the protective cover 210. There is no need to align the waterproof cover 220 with the protective cover 210. Just let the waterproof cover 220 gradually approach the protective cover 210, so that the blocking plug 221 gradually extends into the sealing port 214 until the blocking plug 221 completely penetrates the sealing port 214. In this way, the waterproof cover 220 is installed in the protective cover 210 and begins to block the charging port 110.
[0045] Therefore, in order to prevent the waterproof cover 220 from falling off the housing 100, it is necessary to prevent the stopper 222 from falling out of the fixing opening 120 after the stopper 222 is inserted into the fixing opening 120. Therefore, the stopper 222 is in a prism shape, and the width of the top of the stopper 222 is smaller than the width of the bottom of the stopper 222. The width of the fixing opening 120 is between the width of the top of the stopper 222 and the width of the bottom of the stopper 222. After the stopper 222 is inserted into the fixing opening 120, the width of the bottom of the stopper 222 is wider than the width of the fixing opening 120, thereby preventing the stopper 222 from falling out of the fixing opening 120. Specifically, first insert the top of the limit plug 222 into the fixed port 120, and then gradually push the limit plug 222 into the fixed port 120 until the blocking plug 221 is completely inserted into the fixed port 120 to the inside of the shell 100. At the same time, a snap-in groove 223 is provided below the bottom of the limit plug 222. When the limit plug 222 completely enters the inside of the shell 100, the inner wall of the fixed port 120 is snapped on the snap-in groove 223. Through the cooperation of the snap-in groove 223 and the bottom of the limit plug 222, the limit plug 222 is blocked in the shell 100 to prevent the blocking plug 221 from falling out of the fixed port 120, thereby keeping the waterproof cover 220 on the shell 100.
[0046] To facilitate removal of the waterproof cover 220 from the protective case 210, the waterproof cover 220 also includes a lifting member 224, located on a side facing away from the blocking plug 221. Pulling the lifting member 224 allows the blocking plug 221 to be withdrawn from the sealing opening 214. Therefore, when removing the waterproof cover 220 to expose the power port 310 for connection to an external power supply, the lifting member 224 is pulled to gradually withdraw the blocking plug 221 from the sealing opening 214 until the waterproof cover 220 is completely separated from the protective case 210, completing the removal of the waterproof cover 220. To complete charging through the power port 310 and reinstall the waterproof cover 220 within the protective case 210, the lifting member 224 is pushed to gradually move the waterproof cover 220 closer to the protective case 210 until the blocking plug 221 contacts and extends into the sealing opening 214, completing the installation of the waterproof cover 220. A pulling port 2241 is provided on the pulling member 224 for easy operation, which provides a position for pulling the pulling member 224, making the process of pulling the pulling member 224 more convenient, and is conducive to quickly removing the waterproof cover 220 from the protective cover 210, thereby improving the charging efficiency of the flashlight.
[0047] When the front end of the protective sleeve 210 extends into the charging port 110 and enters the housing 100, it is necessary to prevent the front end of the protective sleeve 210 from shaking on the inner wall of the housing 100. Since the front end of the protective sleeve 210 is mounted on the outer ring of the power supply port 310, if the front end of the protective sleeve 210 shakes, it will cause the power supply port 310 to shake as well, affecting the use of the power supply port 310 and even causing the power supply port 310 to fall off the light-emitting circuit assembly 300. Therefore, to prevent the front end of the protective sleeve 210 from shaking within the housing 100, the protective sleeve 210 is further provided with a stopper 215. Specifically, it is arranged on the outer ring of the front end of the protective sleeve 210 and is mounted on the inner wall of the housing 100 to prevent the protective sleeve 210 from shaking and affecting the power supply port 310. The additional stopper 215 also prevents the protective sleeve 210 from falling out of the housing 100 through the charging port 110, thereby enhancing the stability of the overall structure of the flashlight and making the flashlight suitable for a wider range of usage scenarios.
[0048] A flashlight, in addition to the waterproof structure 10 of the present application, also includes a lens 20 and a power supply 30. The lens 20 is mounted on the housing 100, specifically at the open end of the housing 100. When the lens 20 is installed, the light emitted by the light-emitting circuit assembly 300 is further diffused by the lens 20, thereby improving the lighting effect of the flashlight. The power supply 30 is mounted in the housing 100, specifically on the side of the light-emitting circuit assembly 300 away from the lens 20. The power supply 30 is electrically connected to the light-emitting circuit assembly 300, thereby supplying power to the light-emitting circuit assembly 300 through the power supply 30, so that the light-emitting circuit assembly 300 can operate and emit light, ensuring that the flashlight can operate continuously. In addition, a first bracket 40 is further provided between the power supply 30 and the light-emitting circuit assembly 300, and the first bracket 40 separates the power supply 30 from the light-emitting circuit assembly 300 to avoid direct contact between the light-emitting circuit assembly 300 and the power supply 30, thereby preventing the light-emitting circuit assembly 300 from affecting the use of the power supply 30 when it is heated during operation.
[0049] In addition, the flashlight also includes a second bracket 50, which is installed on the side of the inner wall of the shell 100 close to the lens 20 for installation of the light-emitting circuit assembly 300. The second bracket 50 can fix the position of the light-emitting circuit assembly 300 to prevent the light-emitting circuit assembly 300 from shaking due to movement during use, thereby preventing the light-emitting circuit assembly 300 from being damaged and affecting the use of the flashlight.
[0050] Even if the flashlight is rechargeable, the battery inside the flashlight still has a service life. After multiple charge and discharge cycles, the battery life will gradually decrease. At this time, even if the battery is fully charged, the flashlight cannot be used continuously. Therefore, it is necessary to replace the power supply 30 in the flashlight when the battery life does not meet the requirements. Therefore, a mounting plate 130 is provided at the end of the housing 100 away from the lens 20. The mounting plate 130 is detachably mounted on the housing 100. When the power supply 30 needs to be replaced, the mounting plate 130 is removed, the power supply 30 is taken out of the housing 100, and then a new power supply 30 is replaced. Finally, the mounting plate 130 is reinstalled on the housing 100 to complete the replacement of the power supply 30.
[0051] Therefore, when using the waterproof component 200 in the flashlight in this application to block the charging port 110 of the shell 100 to prevent water from entering, first install the protective cover 210 in the charging port 110 so that the connecting port 213 is sleeved on the outer ring of the power supply port 310, and at the same time install the blocking block 215 on the inner wall of the shell 100. After the installation is completed, the limit plug 222 in the waterproof cover 220 is inserted into the fixing port 120 to keep the waterproof cover 220 on the shell 100, and finally push the pulling piece 224 so that the blocking plug 221 gradually extends into the sealing port 214, thereby installing the waterproof cover 220 on the protective cover 210 to complete the blocking of the charging port 110.
[0052] When the waterproof cover 220 needs to be removed from the protective cover 210 to expose the power supply port 310 for connection to an external power supply device, the lifting member 224 is pulled to move the lifting member 224 away from the protective cover 210, driving the blocking plug 221 to be gradually pulled out from the sealing port 214 until the blocking plug 221 is completely separated from the sealing port 214. In this way, the waterproof cover 220 is removed from the protective cover 210, and an external power supply device can be connected to the power supply port 310 to supply power to the flashlight.
