Description

Technical Field

[0001] This utility model relates to the technical field of fishing floats, and more specifically, to a fishing float that automatically lights up in water and has easily replaceable batteries. Background Technology

[0002] In the current consumer fishing float market, many luminous fishing float devices still rely on relatively traditional and cumbersome operation methods. Most of these devices require users to manually turn on the light before use, then place them in the water and adjust them to the appropriate depth before they can be used. This process not only increases the user's preparation time but also easily leads to poor lighting effects or undesirable float positioning due to improper operation.

[0003] Because each use requires repeatedly performing the manual lighting step, this undoubtedly increases time costs and reduces efficiency. Especially at night or in low-light environments, users may need to attempt multiple times to successfully light the float and place it in the water. This inconvenient process can easily lead to user frustration and fatigue. Over time, this significantly reduces overall user satisfaction, impacting the device's market competitiveness and user loyalty. Therefore, simplifying the operation process and improving efficiency are crucial to enhancing the user experience of luminous fishing float devices. Utility Model Content

[0028] Example 1 like Figure 1-6 As shown, this utility model provides a fishing float that automatically lights up in water and has easily replaceable batteries, including: an upper body 1, a lower body 2, a PCB assembly 3, an LED 4, a button battery 5, a metal shaft 6, a battery door assembly 7, a battery box 8, a waterproof ring 9, and a negative electrode spring 10.

[0029] In a preferred embodiment, in this application, the upper body 1 and the lower body 2 are ultrasonically welded into a sealed whole, and the sealing is completed by ultrasonic mold lowering; the LED 4 and the negative electrode spring 10 are disposed on the PCB assembly 3; the PCB assembly 3 is fixed to the lower body 2; a battery box 8 is also disposed on the lower body 2; a battery door assembly 7 is also disposed on the battery box 8; a waterproof ring 9 is also disposed on the battery door assembly 7; the button battery 5 is disposed in the battery box 8; two round holes are also disposed on the lower body 2, and a metal shaft 6 is disposed in the round holes, with the metal shaft 6 slightly protruding from the lower body 2, the exposed part being connected to the PCB assembly 3. The battery door 7, with the waterproof ring 9 and the positive electrode connecting spring installed, is aligned with the markings on the lower body and covered. A locking slot is provided on the battery door assembly 7; the battery door assembly 7 is tightened through the locking slot to seal the battery door assembly 7 with the lower body 2. The waterproof ring 9 is fitted around the outer ring of the battery door assembly 7, thereby sealing the battery door assembly 7 with the battery box 8. Tighten the battery door by aligning a coin with the slot on the battery door, thus creating a seal between the battery door assembly and the lower body.

[0030] In this application, as a preferred embodiment, the battery box 8 is provided with two LR41 button batteries, which are arranged according to the positive and negative markings.

[0031] In this application, the fishing float body is made of ABS+ABS-758 (transparent ABS) and formed by injection molding.

[0032] In a preferred embodiment, the smaller diameter end of the metal shaft 6 is disposed in the circular hole of the lower body 2. The smaller diameter end of the metal shaft 6 is interference-fitted with the circular hole of the lower body 2. In a preferred embodiment of this application, a clamp is used to drive the metal shaft into the lower body, so that the exposed part of the metal shaft root effectively contacts two points on the PCB (contact spring). The smaller diameter portions of the two metal shafts driven into the lower body are tightly fitted together with the contact surfaces of the holes in the lower body to form a sealed state.

[0033] In a preferred embodiment of this application, the center of gravity of the fishing float is offset to the left, so the device will tilt when placed in the water. Figure 1As shown, the float floats in the water (while the illuminated end is always above the water surface, allowing the user to clearly see the float). The fishing float uses a built-in weight 11 to shift the float's center of gravity to the left.

[0034] Once the device is submerged in water, the two metal shafts, with one end exposed, sink to the bottom, creating a short circuit. The control chip on the PCB receives the signal and sends a command to turn on the switch, activating the LED. While submerged, the switch remains on, ensuring continued operation and providing an extended battery life of over 72 hours. A temporary water reservoir is designed on the lower part of the device. Even after the device is removed from the water, the reservoir retains water for 3-5 seconds, keeping the float illuminated. The light automatically turns off once the water dissipates.

[0035] 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.
