Description

Technical Field

[0001] This utility model relates to the field of luminous float technology, specifically to an LED constant current luminous float. Background Technology

[0002] Fishing floats are an essential tool for fishing. During fishing, anglers generally rely on the up-and-down movement of the float tip to determine if a fish has taken the bait. The float plays a crucial role in the fishing process. Ordinary floats have different colored sections on the float tip, and the color change of the part floating on the water indicates whether the float is sinking or rising. Luminous floats, however, have a miniature battery inside and an LED light inside the float tip; the LED light illuminates when the power is turned on. Chinese patent CN221931075U discloses an LED luminous float, relating to the field of fishing tackle technology. It includes an upper plastic component, a battery, and a lower plastic component. A plastic connecting cylinder is fixedly connected to the bottom of the upper plastic component. A PCB board is fixedly connected inside the upper plastic component, and an acceleration sensor and an MCU microcontroller are mounted on the PCB board. An FPC flexible circuit board is electrically connected to the top of the PCB board, and the LED beads are electrically connected to the FPC flexible circuit board. The FPC flexible circuit board is connected to the upper plastic component. When fishing at night or in foggy conditions, this LED luminous float will detect the change in speed when a fish takes the bait and pulls the float down. The accelerometer on the PCB board will then transmit this signal to the MCU microcontroller. The MCU microcontroller will then control the LED beads to change color via the PCB board, indicating that a fish has taken the bait and providing timely information to the angler.

[0003] The existing technology has the following shortcomings: In the existing technology, when the battery is installed inside the float, the PCB board is powered on, causing the LED beads to light up. However, when it is necessary to turn off the LED beads and de-power the PCB board, the battery needs to be removed, which is cumbersome to use. Therefore, an LED constant current luminous float is provided to solve the above problems. Utility Model Content

[0004] To solve the problems mentioned above, the technical solution adopted by this utility model is: an LED constant current luminous float, comprising: a floating base, a floating cover threadedly connected to the upper end of the floating base, a PCB board disposed inside the floating cover, a positive power socket disposed at the bottom center of the PCB board, a spring connected to the negative power terminal of the PCB board, a battery body slidably sleeved inside the bottom end of the floating cover, a movable seat slidably connected inside the floating base below the battery body, a float rod connected to the bottom end of the movable seat, and a threaded cavity disposed inside the floating base, with a threaded post threadedly connected inside the threaded cavity.

[0005] As a preferred embodiment of this utility model, the threaded post is fixedly sleeved on the outside of the float rod, a first sealing ring is provided at the top of the threaded post, and a second sealing ring is provided at the bottom of the threaded post.

[0006] As a preferred embodiment of this utility model, a waterproof ring is provided at the connection between the bottom end of the floating base and the float rod, and the float rod slides through the interior of the floating base.

[0007] As a preferred embodiment of this utility model, the battery body head is provided with a positive power terminal post, and a negative electrode ring is provided on the outside of the positive power terminal post on the battery body head, and the negative electrode ring contacts a spring, and the positive power terminal post is directly opposite the positive power socket.

[0008] As a preferred technical solution of this utility model, the float rod is fixedly connected to a rotating column at one end outside the floating base, and the outer circumference of the rotating column is provided with a striped structure.

[0009] As a preferred embodiment of this utility model, a third sealing ring is provided between the floating cover and the floating base, and a light-emitting component is connected to the top of the floating cover.

[0010] As a preferred embodiment of this invention, the battery body is electrically connected to a junction field-effect transistor, a resistor, and at least one light-emitting component.

[0011] The present invention has the following advantages: the power supply of the PCB board can be turned on or off by manually turning the rotating column, so that the light-emitting component can be lit or turned off. The structure is compact, the operation is convenient, and the circuit can be configured with one or more LED lights.

[0012] This solution uses a JFET (Junction Field Effect Transistor) N-type transistor as the core component, along with a resistor R and a light-emitting diode (LED), to ensure a constant current to the light-emitting float. This allows the float to emit light at a constant rate, reducing eye strain and fatigue during nighttime use. It also improves constant current efficiency and extends battery life to a greater extent. Attached Figure Description

[0020] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] Please refer to the following: Figures 1-6This utility model discloses an LED constant current luminous float, comprising: a floating base 1, a floating cover 2 threadedly connected to the upper end of the floating base 1, a PCB board 3 disposed inside the floating cover 2, a power positive terminal socket 4 disposed in the middle of the bottom end of the PCB board 3, a spring 5 connected to the negative terminal of the power supply of the PCB board 3, a battery body 6 slidably sleeved inside the bottom end of the floating cover 2, a movable seat 8 slidably connected inside the floating base 1 below the battery body 6, a float rod 9 connected to the bottom end of the movable seat 8, a threaded cavity 10 disposed inside the floating base 1, and a threaded post 11 threadedly connected inside the threaded cavity 10.

[0024] The threaded post 11 is fixedly sleeved on the outside of the float rod 9. A first sealing ring 12 is provided at the top of the threaded post 11, and a second sealing ring 13 is provided at the bottom of the threaded post 11. When the threaded post 11 moves downward in the threaded position, the second sealing ring 13 can enhance the sealing effect. Similarly, when it moves upward in the position, the sealing effect is enhanced. A waterproof ring 14 is provided at the connection between the bottom of the floating base 1 and the float rod 9. The waterproof ring 14 can ensure the sealing between the float rod 9 and the floating base 1. The float rod 9 slides through the interior of the floating base 1.

[0025] Combination Figure 3 and Figure 4 As shown, the battery body 6 has a positive power terminal 7 at its head, and a negative electrode ring is located outside the positive power terminal 7 at the head of the battery body 6, with the negative electrode ring contacting the spring 5. The positive power terminal 7 is directly opposite the positive power socket 4. A rotating column 16 is fixedly connected to one end of the float rod 9 outside the floating base 1. The outer circumference of the rotating column 16 is provided with a striped structure. A third sealing ring 15 is provided between the float cover 2 and the floating base 1 to ensure the sealing between the float cover 2 and the floating base 1. A light-emitting component 17 is connected to the top of the float cover 2. The components of the light-emitting component 17 are clearly described by Chinese Patent CN221931075U.

[0026] Combination Figure 5 , Figure 6 As shown, this solution uses a JFET (Junction Field-Effect Transistor) as the core component. The JFET is integrated on PCB board 3 and powered by battery body 6. The constant current principle is as follows:

[0027] When the junction field-effect transistor (Q) is in the saturation region, the drain current Id is controlled by Vgs;

[0028] The drain resistance Rs generates a voltage drop Vs = Id * Rs, which makes Vgs = -Vs, forming negative feedback and stabilizing the current;

[0029] When the battery voltage drops, as long as Vds is greater than |Vp-Vgs|, the junction field-effect transistor can still maintain a constant current.

[0030] The circuit is composed of a junction field-effect transistor (N-type transistor), a resistor R, and a light-emitting diode (LED); the circuit can be configured with one or more LEDs (light-emitting component 17).

[0031] Specifically, when using this utility model, simply manually turning the rotating column 16 will cause the float rod 9 to rotate, which in turn causes the float rod 9 to rotate along with the threaded column 11. The threaded column 11 then moves upward or downward in the threaded cavity 10. When it moves upward, it can push the movable seat 8, which in turn pushes the battery body 6, causing the positive terminal 7 on the battery body 6 to be inserted into the positive terminal socket 4. The spring 5 then contacts the negative terminal of the battery body 6, thereby connecting the power supply to the PCB board 3 and causing the light-emitting component 17 to light up. Conversely, when it moves downward, the movable seat 8 moves away from the battery body 6, and under the elastic force of the spring 5, it pushes the battery body 6, causing the positive terminal 7 on the battery body 6 to be pulled out of the positive terminal socket 4, thereby de-energizing the PCB board 3.

[0032] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0033] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
