Description

Technical Field

[0001] The utility model relates to the technical field of fishing gear, in particular to an underwater lighting float. Background Art

[0002] Night fishing refers to fishing activities carried out at night. Due to the dim light at night, lighting equipment is needed to help anglers observe the underwater environment. The night fishing lighting float is a very important equipment for night fishing. It can help anglers clearly see the underwater environment in insufficient light, so as to accurately judge whether there is a fish bite. Some anglers also use underwater cameras for night fishing to observe the underwater fish situation. The night fishing lighting float also needs to provide light for the camera.

[0003] For example, the Chinese patent with application number 202122540322.3, a float high light, includes a float body, a PCB board is fixedly installed on the top of the float body, a switch assembly is provided on the PCB board, the switch assembly includes a MOS tube switch and a sensing point fixedly installed on the top of the PCB board, and the MOS tube switch and the sensing point are electrically connected to the lightless lamp bead through the circuit layer printed on the PCB board; when in use, the float body is sunk into the water with the night fishing camera, the sensing point contacts the water, and the water encounter signal is transmitted to the MOS tube switch, the MOS tube switch is closed to connect the circuit, and the lightless lamp bead lights up.

[0004] Because the sensing point is a conductive column that conducts electricity through water, when immersed in water, there is a situation where electricity is conducted through water and a low-voltage current is generated. Fish are very sensitive to low-voltage current. When the fish body is stimulated by the low-voltage current, it will produce a behavioral reaction called electro-sensory reaction, and then turn around or escape from the area of ​​current stimulation. In addition, because electronic components are immersed in water for a long time, the electronic components will react chemically with water to produce acidic substances, etc., which change the pH value of the water. The fish are very sensitive to sudden changes in pH value. The acidic substance can easily make the fish feel uncomfortable and flee from the area, not taking advantage of the angler to catch fish, and at the same time, causing damage to the environment. Utility Model Content

[0005] The utility model is intended to provide an underwater lighting float to solve the technical problems in the prior art that the float placed in the water is conductive and produces a chemical reaction with the water, causing the hardware to age quickly, damaging the underwater environment, producing odor and electric current that makes fish notice and flee from the observation area, and cannot be intelligently controlled to achieve energy saving.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an underwater lighting float, including a float body, a PCB board and a battery, the float body is provided with a mounting groove for placing the PCB board and the battery, a lighting component and a key switch for controlling the lighting component are installed on the PCB board, the key switch is a sealed key, the mounting groove is filled with a curable packaging liquid, and the curable packaging liquid seals and wraps the battery, the PCB board and the electrical connection between the PCB board and the key switch.

[0007] The principles and advantages of this solution are: compared with the prior art that relies on water for electrical conduction, this solution encapsulates all conductive electronic components in the float to avoid contact with water for conduction, and sets the switch of the lighting component to a sealed button, which can be manually controlled according to the lighting of the lighting component. On the basis of meeting the requirements of ready-to-use, the entire device will not generate electricity and chemical reactions with water, thereby avoiding damage to the internally encapsulated electronic components, and will not pollute the environment or scare the fish; the solidified encapsulation liquid is a liquid with fluidity during the encapsulation process, and can flow with gravity to completely fill the installation groove. When the encapsulation is completed, the solidified encapsulation liquid is converted from liquid to solid after ultraviolet irradiation or other curing operations, and has a certain strength to protect the internal packaging; the battery and the PCB board are encapsulated as a whole and embedded in the float body, and only one encapsulation is required, simplifying the production process; after the curable encapsulation liquid is filled, the curable encapsulation liquid is cured to form a sealed lining, and the battery and the PCB board are fixedly sealed in the float body.

[0011] The beneficial effect of this improvement is: in order to make the package more firm and avoid excessive use of curable encapsulation liquid causing the overall device to be too dense and lose floating performance, the size of the mounting groove should be consistent with the size of the PCB board and the battery, and should not be too large; but this means that the air at the bottom of the mounting groove cannot be discharged in time during packaging, resulting in the curable encapsulation liquid being unable to fill the mounting groove, resulting in incomplete packaging; the groove is provided so that when pouring the curable encapsulation liquid, the curable encapsulation liquid can flow directly into the bottom of the groove along the groove, fill it from the bottom upwards, and ensure that the groove can be completely filled with the curable encapsulation liquid.

[0012] As an improvement, the groove is an arc-shaped groove.

[0013] The beneficial effect of this improvement is that the arc-shaped groove can make the flow of the curable encapsulation liquid smoother.

[0016] As an improvement, a lighting control chip and a transistor for controlling the brightness of the lighting component are installed on the PCB board. The lighting control chip and the transistor are connected in series to the circuit where the lighting component and the battery are located, and the positive pole of the push switch is electrically connected to the lighting control chip.

[0017] The beneficial effect of this improvement is that the transistor voltage is controlled by the lighting control chip, and then the current flowing to the lighting component is controlled, so that the number of times the button switch is pressed can determine the number of brightness levels of the current lighting component to adapt to the lighting needs of different fishing environments, and the simple structure meets the requirements of a small and light fishing float.

[0018] As an improvement, the lighting assembly includes a plurality of LED light emitting diodes, and the plurality of LED light emitting diodes are connected in parallel.

[0019] The beneficial effect of this improvement is that the LED light emitting diode is an LED infrared lamp, and the specific number of the LED infrared lamps can be designed according to demand. By increasing the number of LED light emitting diodes to increase the strongest lighting brightness of the device, high brightness requirements can be met.

[0035] A mounting groove 6 is provided in the float body 1, and the PCB board 2 and the battery 3 are both placed in the mounting groove 6. The shape of the mounting groove 6 matches the shape of the PCB board 2 and the battery 3. In this embodiment, the PCB board 2 and the battery 3 are both rectangular, and the mounting groove 6 is rectangular. The battery 3 is placed at the bottom of the mounting groove 6, the PCB board 2 is located above the battery 3, and the upper surface of the PCB board 2 is lower than the notch of the mounting groove 6.

[0036] An arc-shaped groove 7 is provided on one side wall of the mounting groove 6, and two ends of the arc-shaped groove 7 are connected to the groove opening and the groove bottom of the mounting groove 6. The float body 1 is also embedded with a lifting ring 8, the ring body of the lifting ring 8 is located outside the float body 1, and the lifting handle of the lifting ring 8 is located inside the float body 1. A groove 9 is provided on the groove bottom of the mounting groove 6, one end of the groove 9 is connected to the arc-shaped groove 7, and the other end of the groove 9 is a through hole that penetrates one end of the float body 1 and is connected to the outside world, and the end of the float body 1 that is penetrated is the end away from the arc-shaped groove 7; the lifting handle of the lifting ring 8 is placed in the groove 9 through the through hole from the outside world.

[0037] The installation groove 6 is filled with a curable encapsulation liquid, and the PCB board 2 and the battery 3 are sealed in the float body 1. The welding points between the type-c charging interface 4 and the key switch 5 and the PCB board 2 are immersed in the curable encapsulation liquid, and the plug part of the type-c charging interface 4 and the part of the key switch 5 with the soft rubber waterproof keycap are located outside the curable encapsulation liquid. The curable encapsulation liquid is poured into the bottom of the installation groove 6 through the arc groove 7, wrapping the PCB board 2 and the battery 3, and part of the curable encapsulation liquid flows into the groove 9 to fix the handle of the hanging ring 8 in the groove 9, and fills the gap between the through hole and the handle, so that the hanging ring 8 is fixed to the float body 1.

[0038] As attached Figure 3 As shown, a lighting assembly 10 and a lighting control chip 11 are also installed on the PCB board 2, the positive pole of the key switch 5 is electrically connected to the lighting control chip 11, the negative pole of the key switch 5 is grounded, and the positive poles of the lighting control chip 11 and the lighting assembly 10 are electrically connected to the battery 3 to obtain electrical energy; the lighting control chip 11 is connected in series with the lighting assembly 10 through a transistor 12 to control the luminous brightness of the lighting assembly 10; the transistor 12 is an NPN transistor 12, the base of the transistor 12 is electrically connected to the pin of the lighting control chip 11, the emitter of the transistor 12 is grounded, and the collector of the transistor 12 is electrically connected to the negative pole of the lighting assembly 10, and the lighting assembly 10 is four LED light emitting diodes connected in parallel, wherein, in this embodiment, the LED light emitting diode adopts an LED infrared lamp.

[0039] The lighting control chip 11 can adopt a control chip with high efficiency and stability such as LM2596, XL4015, MP2307 and LM2678, which can reduce the input voltage to a lower output voltage and has a wide input voltage range and high output current capability.

[0040] When the push button switch 5 is pressed, an electrical signal is sent to the lighting control chip 11, and the lighting control chip 11 controls the circuit connecting the lighting component 10 and the battery 3 to be closed, so that the four LED light-emitting diodes in the lighting component 10 emit light to provide light for night fishing; when the brightness needs to be adjusted, a program is programmed into the lighting control chip 11, and the number of times the push button switch 5 sends an electrical signal to the lighting control chip 11 is used to control the voltage of the transistor 12, thereby controlling the current size of the transistor 12 and the circuit, and then controlling the brightness.

[0041] For example, when the button switch 5 is pressed for the first time, the lighting control chip 11 controls the lighting component 10 to be 100% lit; when the button switch 5 is pressed for the second time, the lighting control chip 11 controls the lighting component 10 to be 70% lit; when the button switch 5 is pressed for the third time, the lighting control chip 11 controls the lighting component 10 to be 50% lit; when the button switch 5 is pressed for the fourth time, the lighting control chip 11 controls the lighting component 10 to be disconnected from the circuit where the battery 3 is located, and the lighting component 10 is turned off, and one round ends. When the button is pressed next time, the next round of control will start.

[0042] The lighting control chip makes the lighting components intelligently adjustable, and anglers can control the lighting components to turn on and off as needed. Because some night fishing environments are darker, weaker brightness can meet lighting needs. The brightness of the lighting components is adjustable, which can meet the needs of high brightness while also meeting the needs of low brightness and energy saving, thereby extending the battery power supply time.

[0043] As attached Figure 4 As shown, since the socket of the type-c charging interface 4 is exposed to the outside world and will come into contact with water when in use, a protection circuit is provided for the battery 3 to prevent the type-c charging interface 4 from discharging or overcharging when the battery 3 is charged. The PCB board 2 also includes: a prompt component 13 and a charging control chip 14. The type-c charging interface 4 is electrically connected to the charging control chip 14 through the prompt component 13, and the positive electrode of the battery 3 is electrically connected to the pin of the charging control chip 14, so that the type-c charging interface 4, the charging control chip 14 and the battery 3 are connected in series in sequence. The prompt component 13 includes two LED light-emitting diodes of different colors, the two LED light-emitting diodes of different colors are connected in parallel, and the negative electrodes of the two LED light-emitting diodes of different colors are electrically connected to different pins of the charging control chip 14 respectively.

[0044] The charging control chip 14 may be an AVR ATtiny85 control chip, which has a small size and a package size of only 4mm×4mm, and is very suitable for use in small spaces or portable devices. Its low power consumption makes it particularly suitable for battery-powered devices or other energy-saving applications.

[0045] The charging control chip 14 detects the voltage of the battery 3 to obtain the power status of the battery 3 at this time. When the charging control chip 14 does not receive the charging signal from the type-c charging interface 4, the circuit between the type-c charging interface 4 and the battery 3 is always disconnected, so that the type-c charging interface 4 can only charge but not discharge, avoiding disturbing the fish school and polluting the environment due to low voltage discharge. At the same time, it avoids the type-c charging interface 4 consuming battery power to achieve green energy saving; when the user connects the type-c charging interface 4 to the power supply for charging, the charging control chip 14 receives the charging signal, and when the charging control chip 14 detects that the battery 3 is not saturated with electricity, the circuit between the type-c charging interface 4 and the battery 3 is connected, and one of the LED light-emitting diodes of the control prompt component 13 is lit. In this embodiment, the color of the diode is red to indicate that it is in a charging state; when the charging control chip 14 detects that the power of the battery 3 is saturated at this time, the circuit between the type-c charging interface 4 and the battery 3 is disconnected, and another LED light-emitting diode of the control prompt component 13 is lit. In this embodiment, the color of the diode is green to indicate that the battery 3 is fully charged. Please disconnect the power supply in time to realize intelligent monitoring of the battery power, avoid battery overcharge, and thus extend the battery life.

[0046] Except for the key switch 5 and the type-c charging port 4, all electronic components and circuits are encapsulated in a curable encapsulation liquid. The curable encapsulation liquid needs to be transparent. In order to ensure the floating performance of the float, a transparent resin material is used as the curable encapsulation liquid so that the LED light will not be blocked.

[0047] When fishing at night, the float body 1 is fixed to other fishing gears through the hanging ring 8, and the angler controls the brightness of the lighting assembly 10 by pressing the key switch 5 multiple times to meet different fishing environment requirements.

[0048] Moreover, the float structure can play different roles in various scenarios such as on the shore, on the water surface and underwater. When the float is on the shore, the brightness of the lighting component can be adjusted to the maximum to serve as a night light. When the float floats on the water surface, it acts as a luminous fish float, making it easier for anglers to find the sinking of the fish float when the fish bites the bait and reel in the line in time at night. The brightness of the lighting component can be adjusted to keep the lighting component at a dim light so that it can be observed by the angler. At the same time, the faint blue light emitted by the lighting component can also attract fish. When the float sinks underwater, the float is bound to the night fishing camera and sinks into the water together with the night fishing camera, providing a light source for the night fishing camera to shoot.

[0049] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
