TECHNICAL FIELD
[0001] The utility model relates to the fishing tackle technical field, especially to a water-leaving luminous pointer. BACKGROUND
[0002] Currently, in the night fishing activities, the fisher usually needs to rely on external light source or luminous device to locate the position of fishing line and fishhook. The common luminous devices on the market mainly include luminous lead sinker and LED light luminous lead sinker. The luminous lead sinker emits weak light in the dark through the light storage material, but its brightness is limited and the duration is short, which is difficult to meet the actual demand. While the LED light luminous lead sinker has high brightness, but its luminous state is continuous, and it keeps constant brightness whether on the water surface or underwater. This continuous luminous characteristic has obvious defects: when the lead sinker is thrown into the water, the light of LED is easy to disturb the fish school, affect the normal foraging behavior of fish, and thus reduce the success rate of fishing. In addition, the existing luminous lead sinker has single function, only provides lighting or counterweight effect, cannot automatically switch the luminous state according to the environment such as underwater or water surface, leading to poor use experience. Therefore, it is necessary to provide a water-leaving luminous pointing device which can automatically control the luminous state according to the environment, provide lighting assistance when leaving water, and automatically extinguish after entering water to avoid disturbing the fish school, and at the same time improve the convenience and efficiency of night fishing. In the prior application of the applicant with publication number "CN119302276A", the water entering state and water leaving state are judged by using the capacitive sensing mode, which may cause capacitive sensing error due to air humidity, so the applicant improves it, and the scheme provided by the utility model can more accurately judge the water entering state and water leaving state. CONTENT OF THE UTILITY MODEL
[0003] The utility model aims to solve at least one of the above technical problems.
[0004] To solve the above problems, the first purpose of the utility model is to provide a water-leaving luminous pointer, which comprises a power supply and further comprises: a shell; a photoelectric circuit board, the luminous circuit board is placed in the shell, the luminous circuit board is provided with a contact, a level sensing device and a luminous device, wherein the level sensing device is connected with the luminous device; wherein the contact is in the on-state when entering water, the level sensing device is in the off-state, and the luminous device is extinguished; when leaving water, the contact is in the off-state, the level sensing device is in the on-state, and the luminous device emits light.
[0005] The pointer can automatically detect whether it is in water through the contact and the level sensing device. When entering the water, the contact is in the on state, the level sensing device becomes off, the circuit is automatically disconnected, and the light emitting device is turned off to avoid disturbing the fish. When leaving the water, the contact is in the off state, the level sensing device becomes on, the circuit resumes conduction, and the light emitting device lights up, which helps the fisherman quickly locate the position of the fishing line and the hook. Compared with the traditional lead sinkers or luminous floats that emit light continuously, this device only emits light when it is out of the water, which does not affect the activities of fish and provides clear visual guidance for the fisherman, improving the convenience and success rate of night fishing. Since the light emitting device only works above the water surface, unnecessary power consumption is reduced, the service life of the battery is prolonged, and it is suitable for long-term night fishing needs. The shell packaging design has good waterproof performance, ensuring stable operation of the circuit underwater, and is easy to install and fix on the fishing line without affecting normal casting and line winding operations. It can replace part of the weight function of lead sinkers and provide intelligent light guidance, suitable for various fishing scenes such as sea fishing and freshwater fishing, improving practicality.
[0006] In any of the above technical solutions, the light emitting circuit board is provided with a safety resistor connected to the light emitting device.
[0007] The safety resistor acts as a current limiting resistor, which can effectively limit the current in the circuit, avoid the light emitting device from being burned out due to excessive current caused by voltage fluctuations or short circuit, and improve the reliability and service life of the device. In a humid or water-conductive environment, the on state of the contact may not be stable, and the safety resistor can reduce the impact of current surges on the level sensing device or other control elements, ensuring more accurate switching action and avoiding false triggering, such as still dim or flickering after entering the water. If the circuit is accidentally short-circuited, such as abnormal conduction of the contact, the safety resistor can limit the short-circuit current, reduce the abnormal power consumption of the battery, and avoid the battery from being quickly depleted or damaged. Due to the large difference in conductivity of different water areas such as freshwater and seawater, the safety resistor can adjust the working current of the circuit, so that the device can operate stably in different water qualities, avoiding abnormal light emitting device or component damage caused by excessive conductivity.
[0008] In any of the above technical solutions, the light emitting circuit board is provided with a bias resistor connected to the power supply.
[0009] The bias resistor is usually connected to the gate of the level sensing device, which can ensure that the level sensing device is in a stable off or on state when not triggered, avoiding false action caused by sensing interference such as leakage current in a humid environment, and improving the anti-interference ability of the circuit.
[0010] In any of the above technical solutions, the level sensing device uses a MOS tube.
[0011] The MOS tube has a high-speed switching characteristic, can quickly cut off the circuit to extinguish the light at the moment of water contact, and immediately turns on the circuit to light up when leaving the water, realizes millisecond-level state switching, ensures the sensitive reaction of the pointer, and improves the use experience. The MOS tube has extremely low internal resistance of only milliohm level when conducting, hardly consumes additional electric energy; when cut off, the leakage current is extremely small, significantly reduces the static power consumption, greatly prolongs the battery endurance time, and is suitable for long-time night fishing demand. The MOS tube is controlled by a voltage signal to turn on and off, has no mechanical parts, avoids the wear problem of the traditional physical switch, does not attenuate in long-term use, and has extremely high reliability. The MOS tube can work efficiently under low voltage of 3V or below, is suitable for small power sources such as button batteries, and is beneficial to the miniaturization and lightweight design of the device.
[0012] In any of the technical solutions, the contact point includes a first contact point and a second contact point, and the first contact point is connected with the power supply.
[0013] The first contact point is directly connected with the power supply, and the second contact point is connected with the gate of the MOS tube. When the two contact points contact the water body at the same time, a current loop is formed to trigger the MOS tube to turn off, so that the light is extinguished only when the device is really in the water, and misjudgment caused by slight contact such as moisture and splashing water is avoided. The first contact point is directly connected with the power supply without the need of additional series elements, which reduces the complexity of the circuit, reduces the failure rate, improves the signal transmission efficiency, and makes the MOS tube control more rapid and accurate. The double contact points need to contact the water body at the same time to trigger the action, which can prevent accidental short circuit of a single contact point, such as abnormal circuit caused by collision with metal objects, and improves the safety.
[0014] In any of the technical solutions, an elastic element is arranged between the power supply and the light-emitting circuit board.
[0015] The elastic element can absorb the mechanical impact force generated by casting, vibration or collision, avoid the hard contact between the battery and the circuit board, and prevent loosening, displacement or poor contact, thereby improving the durability and reliability of the device. The elastic element continuously applies pressure to ensure that the battery and the circuit board are tightly attached, prevents the power supply from being temporarily disconnected due to vibration or water flow impact, and avoids flickering or abnormal extinguishing of the light. When the elastic element presses the battery, the internal gap is reduced, the risk of water entering the circuit is reduced, and the waterproof performance is further improved by the sealing design of the shell. The elastic structure allows the user to easily disassemble and replace the battery without tools. The old battery can be easily pressed out, and the new battery can be automatically reset and fixed after insertion, which is convenient to maintain.
[0016] In any of the technical solutions, the shell includes a protective shell, and the light-emitting circuit board is arranged in the protective shell.
[0017] The protective shell completely wraps the light-emitting circuit board, effectively isolates water vapor, rain or spray erosion, avoids circuit short circuit or component oxidation, and ensures that the device works stably in water or humid environment for a long time. The shell provides rigid support for the circuit board to prevent deformation, fracture or solder shedding of the circuit board caused by throwing, collision or fishing line pulling, especially suitable for complex outdoor use scenarios. The protective shell can be made of heat-conducting materials such as engineering plastics or designed to have a heat dissipation structure to avoid overheating of the light-emitting device or MOS tube during long-time work, thereby prolonging the service life of electronic components. The circuit board is pre-packaged in the shell to form a modular structure, facilitating batch production and assembly, and reducing the difficulty of subsequent maintenance, such as replacing the battery without directly contacting the circuit board.
[0018] In any of the above technical solutions, the shell further comprises a flexible shell, and the flexible shell is sleeved with the protective shell.
[0019] The flexible shell is made of elastic materials such as silica gel or TPU to wrap the protective shell and form a rigid-flexible composite structure to absorb the instantaneous impact force when the fishing rod is thrown, avoid the rigid shell from being broken, disperse stress through deformation when the fishing rod hits hard objects such as rocks or ship bodies, protect the internal circuit board, and reduce the damage of high-frequency vibration caused by water flow impact when the fishing line is reeled in. The double-layer shell cooperates to realize multi-level protection, the flexible shell elastically wraps the joint of the protective shell to prevent large particles from entering, and the structure of the protective shell itself forms a main waterproof layer.
[0020] In any of the above technical solutions, the shell is provided with a through hole, and the through hole is located on the outer side of the shell.
[0021] The through hole design allows the fisherman to directly pass the fishing line through without the need for additional connectors or binding line assistance, realizes quick installation, and the axis of the through hole is consistent with the stress direction of the fishing line to avoid lateral tension from causing the shell to rotate or displace.
