Description

Technical Field

[0001] This invention relates to the field of fishing equipment, and more particularly to an automatic fishing float that is easy to assemble. Background Technology

[0002] The applicant's prior patent "2025200773516" discloses an automatic fishing float. In that patent, the disclosed fishing float includes an upper shell and a lower shell, which are detachably and sealed together by a threaded structure, forming the outer shell of the float. However, in actual production, it was found that the molds for producing the threaded shell are complex, resulting in high production costs and making widespread adoption difficult. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides an easy-to-assemble automatic fishing float. By splitting the shell into a left shell and a right shell, the manufacturing difficulty of the shell is reduced, the assembly difficulty of the shell is lowered, and the purpose of reducing production costs and improving production efficiency is achieved.

[0004] The technical solution of this invention is implemented as follows:

[0005] An easy-to-assemble automatic fishing float includes a housing consisting of a left shell and a right shell fixedly connected together. The left shell and the right shell enclose a cavity. An air extraction mechanism is provided inside the cavity. The air extraction mechanism includes a shell, which is fixedly connected to the cavity and its outer peripheral surface is tightly fitted to the inner wall of the housing. The shell divides the cavity into a first receiving cavity and a second receiving cavity in a vertical direction. The air extraction mechanism is used to draw air from the external environment into the first receiving cavity. The side wall of the first receiving cavity is provided with a drainage structure for discharging its internal liquid. The housing is provided with an air extraction channel, and the first receiving cavity is connected to the external environment through the air extraction channel.

[0006] In this design, the float's outer shell consists of a sealed left shell and a right shell. The suction mechanism's outer shell divides the shell's cavity into two independent receiving cavities: a first receiving cavity and a second receiving cavity. The left and right shells have simple structures, allowing for mass production using molds, thus reducing production costs and improving efficiency. Furthermore, the suction mechanism's outer shell also functions as a cavity divider, eliminating the need for additional partitions and further reducing float production costs. When fishing, the float's main body is submerged, and the first receiving cavity is filled with water, causing the float to sink. When the suction mechanism operates, it first drains the water from the first receiving cavity through a drainage structure, and then draws in external air through the suction channel. When the water in the first chamber is discharged, the reaction force of the water flow exerts an upward thrust on the float, causing it to move upwards towards the water surface. After the water is discharged, external air is drawn into the first chamber, increasing the float's buoyancy and causing it to continue moving upwards. In other words, when the air extraction structure is running, the float will dart rapidly upwards towards the water surface. When the air extraction structure stops running, external water flows into the first chamber through the drainage structure, causing the float's overall buoyancy to decrease and the float to sink. By setting the air extraction structure to operate intermittently, the float can be made to bounce up and down in the water, causing the bait on the hook to bounce, realistically simulating the dynamics of live bait in water. The air extraction structure can complete two actions in a single operation: first, the water in the first chamber is discharged, and then external air is drawn into the first chamber. In the second step, the air extraction structure does not need to come into contact with water, reducing the operating resistance and energy consumption of the air extraction structure.

[0007] Preferably, an exhaust fan is provided on the top of the housing, and the interior of the housing, from top to bottom, consists of a motor for driving the exhaust fan, an energy storage component for supplying power to the motor, and a circuit board for controlling the operation of the motor. During operation, the exhaust fan draws air from the external environment into the first receiving cavity.

[0008] Preferably, the outer shell has an internal limiting structure for engaging the outer shell. This limiting structure includes two first locking segments disposed on the inner wall of the left shell and two second locking segments disposed on the inner wall of the right shell. The two first locking segments are spaced apart vertically, and the two second locking segments are also spaced apart vertically. After the left and right shells are connected to form a shell, the upper first and second locking segments form a first limiting ring, and the lower first and second locking segments form a second limiting ring. The limiting areas of the first and second limiting rings are adapted to the outer shell. During actual installation, the outer shell is first placed between the first and second locking segments of the left (or right) shell, then the right (or left) shell is snapped on, at which point the left and right shells are assembled into a shell. Finally, the left and right shells are fixedly connected. The entire installation process is simple and quick.

[0009] Preferably, the energy storage component includes a lithium battery and a wireless charging module for charging the lithium battery. The wireless charging module includes a charging coil, which is vertically arranged and located between the housing and the outer shell. Wireless charging eliminates the need to disassemble the fishing float to replace the power source and also eliminates the need for a charging interface, thus balancing production costs and ease of use.

[0010] Preferably, an all-polar Hall switch is provided at the edge of the circuit board, which is used to send a signal to the circuit board to cut off or turn on the circuit.

[0011] Preferably, the left and right shells are made of rigid plastic, and the contact surfaces of the left and right shells are provided with a stepped structure. The stepped structure includes a protruding ridge on the contact surface of the left shell and a groove on the contact surface of the right shell, the groove being adapted to the protruding ridge. The left and right shells are formed by ultrasonic welding or bonding. By providing the stepped structure, pre-connection before connecting the left and right shells is achieved, improving the accuracy and efficiency of the shell connection.

[0012] Preferably, the drainage structure includes multiple drainage channels spaced apart on the side wall of the shell. Each drainage channel includes an inlet and an outlet, with the bottom surface of the outlet smoothly connected to the top surface of the first limiting ring. The spaced arrangement of multiple drainage channels increases the stability of the float during drainage, ensuring that the float does not tilt as it moves upwards. Furthermore, it ensures that water in the first receiving cavity is completely drained during the phase of increasing buoyancy, and that water quickly enters the first receiving cavity during the phase of decreasing buoyancy.

[0013] Preferably, the fishing float also includes a float tip and a float stem. The float tip is vertically connected to the top of the housing and is made of a hollow rod. The air extraction channel includes a perforation, through which the float tip passes into the first receiving cavity. The float tip is interference-fitted with the perforation, and the float stem is vertically connected to the bottom of the housing. The hollow rod of the float tip not only provides a lightweight advantage but also allows connection between the first receiving cavity and the external environment. This enables the air extraction structure to draw external air into the first receiving cavity through the float tip, eliminating the need for an additional air intake pipe. Furthermore, since the float tip needs to react to fish movements, it is exposed above the water surface, preventing the air extraction structure from drawing water into the first receiving cavity during operation.

[0014] Preferably, the left and right housings are formed by ultrasonic welding.

[0015] Preferably, the left and right housings are bonded together with an adhesive to form the housing.

[0016] The principle and beneficial effects of the present invention, which adopts the above technical solution, are as follows:

[0017] 1. The outer shell is composed of a left shell and a right shell, which simplifies the connection process and improves the connection efficiency;

[0018] 2. The internal structures of the left and right shells are simple, allowing for mass production using molds and reducing production costs;

[0019] 3. Wireless charging of the battery eliminates the need to disassemble the fishing float to replace the power source or design a charging interface, thus balancing production costs and ease of use.

[0020] 4. By setting a limiting structure, the air extraction structure can be directly and accurately inserted into the left or right shell, simplifying the installation of the air extraction mechanism;

[0021] 5. The bottom surface of the liquid outlet is smoothly connected to the top surface of the first limiting ring, which improves the smoothness of water inlet / outlet. Attached Figure Description

[0030] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0032] In this embodiment, the up-down direction refers to the vertical direction of the fishing float itself; the inside-outside direction refers to the direction closer to and farther from the axis of the fishing float.

[0033] The specific embodiments of the present invention are as follows:

[0034] like Figures 1 to 6 As shown, the present invention provides an easy-to-assemble automatic fishing float, comprising a housing 1 consisting of a left housing 10 and a right housing 11 fixedly connected together. The left housing 10 and the right housing 11 enclose a cavity 2. An air extraction mechanism 21 is provided in the cavity 2. The air extraction mechanism 21 includes an outer shell 211, which is fixedly connected in the cavity 2 and its outer peripheral surface is tightly fitted to the inner wall of the housing 1. The outer shell 211 divides the cavity 2 into a first receiving cavity 22 and a second receiving cavity 23 in the vertical direction. The air extraction mechanism 21 is used to draw air from the external environment into the first receiving cavity 22. The side wall of the first receiving cavity 22 is provided with a drainage structure for discharging its internal liquid. The housing 1 is provided with an air extraction channel, and the first receiving cavity 22 is connected to the external environment through the air extraction channel.

[0035] In this design, the outer shell 211 of the float 5 consists of a sealed left shell 10 and a right shell 11. The outer shell 211 of the suction mechanism 21 divides the cavity 2 of the shell 1 into two independent first receiving cavity 22 and second receiving cavity 23. The left shell 10 and right shell 11 have simple structures and can be mass-produced using molds, reducing production costs and improving production efficiency. Furthermore, the outer shell 211 of the suction mechanism 21 also acts as a structure for dividing the cavity 2, eliminating the need for additional dividing components and further reducing the production cost of the float 5. When fishing, except for the float tip 3, the float 5 is located below the water surface. At this time, the first receiving cavity 22 is filled with water, and the float 5 tends to sink. When the suction structure is running, the water in the first receiving cavity 22 is first discharged from the first receiving cavity 22 through the drainage structure, and then external air is drawn into the first receiving cavity 22 through the suction channel. When the water in the first receiving cavity 22 is discharged, the reaction force of the water flow generates an upward thrust on the float 5, causing the float 5 to move upward towards the water surface. After the water in the first receiving cavity 22 is discharged, external air is drawn into the first receiving cavity 22, at which point the buoyancy of the float 5 increases dramatically, and it continues to move upward towards the water surface. That is, when the air extraction structure is running, the float 5 will dart rapidly upward towards the water surface. When the air extraction structure stops running, external water flows into the first receiving cavity 22 through the drainage structure, at which point the overall buoyancy of the float 5 decreases, and the float 5 sinks into the water. By setting the air extraction structure to operate intermittently, the float 5 can be made to bounce up and down in the water in a cycle, causing the bait on the hook to bounce, realistically simulating the dynamics of live bait in the water. The air extraction structure can complete two actions in a single operation: first, the water in the first receiving cavity 22 is discharged, and then external air is drawn into the first receiving cavity 22. In the second step, the air extraction structure does not need to come into contact with water, reducing the operating resistance of the air extraction structure and reducing the operating energy consumption of the air extraction structure.

[0036] like Figure 3 As shown, an exhaust fan 212 is provided on the top of the outer casing 211. Inside the outer casing 211, from top to bottom, are a motor 213 for driving the exhaust fan 212, an energy storage component for supplying power to the motor 213, and a circuit board 215 for controlling the operation of the motor 213. During operation, the exhaust fan 212 draws air from the external environment into the first receiving cavity 22. It can be understood that the various components of the exhaust mechanism 21 mentioned in this embodiment are integrated into the outer casing 211, meaning the exhaust mechanism 21 is approximately a single unit, further reducing the difficulty of installation.

[0037] like Figure 4 and Figure 5As shown, the interior of the outer shell 211 is provided with a limiting structure for engaging the outer shell 211. The limiting structure includes two first locking segments 101 disposed on the inner side wall of the left shell 10 and two second locking segments 111 disposed on the inner side wall of the right shell 11. The two first locking segments 101 are spaced apart in the vertical direction, and the two second locking segments 111 are spaced apart in the vertical direction. After the left shell 10 and the right shell 11 are connected to form the shell 1, the upper first locking segment 101 and the second locking segment 111 are combined to form a first limiting ring, and the lower first locking segment 101 and the second locking segment 111 are combined to form a second limiting ring. The limiting areas of the first limiting ring and the second limiting ring are adapted to the outer shell 211. During actual installation, first place the outer shell 211 between the first clip 101 and the second clip 111 of the left shell 10 (or the right shell 11), then snap the right shell 11 (or the left shell 10) together. At this time, the left shell 10 and the right shell 11 are assembled into shell 1. Finally, fix the left shell 10 and the right shell 11 together. The whole installation process is simple and quick.

[0038] The energy storage component includes a lithium battery 214 and a wireless charging module for charging the lithium battery 214. The wireless charging module includes a charging coil 6, which is vertically arranged and located between the housing 1 and the outer shell 211. The charging coil 6 is positioned between the housing 1 and the outer shell 211, close to the transmitting coil of the external wireless charger, which enables efficient charging of the lithium battery 214. The use of wireless charging eliminates the need to disassemble the float 5 to replace the power supply and also eliminates the need to design a charging interface, thus balancing production costs and ease of use.

[0039] A full-pole Hall switch (not shown) is provided at the edge of the circuit board 215. The full-pole Hall switch is used to send a signal to the circuit board 215 to cut off or turn on the circuit. In actual use, a magnet is used to activate the full-pole Hall switch. The full-pole Hall switch can respond to any magnetic pole, without distinguishing between the S pole or N pole of the magnet, and is suitable for the switches mentioned in this application.

[0040] The left housing 10 and the right housing 11 are made of rigid plastic, such as Figure 6 As shown, a stepped structure is provided on the contact end faces of the left shell 10 and the right shell 11. The stepped structure includes a protruding ridge 102 on the contact end face of the left shell 10 and a groove 112 on the contact end face of the right shell 11. The groove 112 is adapted to the protruding ridge 102. The left shell 10 and the right shell 11 are ultrasonically welded into shell 1. By setting the stepped structure, a pre-connection is achieved before connecting the left shell 10 and the right shell 11, improving the connection accuracy and efficiency of the shell 211. In actual welding, the left shell 10 and the right shell 11 are first pre-installed using the stepped structure, then the shell 1 is fixed using the mold of the ultrasonic welding equipment, and finally the welding is completed.

[0041] The drainage structure includes multiple drainage channels 222 spaced apart on the side wall of the housing 1. Each drainage channel 222 includes an inlet and an outlet, with the bottom surface of the outlet smoothly connected to the top surface of the first limiting ring. The spaced arrangement of multiple drainage channels 222 increases the stability of the float 5 during drainage, ensuring that the float 5 will not tilt as it moves upwards. Furthermore, it ensures that the water in the first receiving cavity can be completely drained during the phase of increasing the buoyancy of the float 5, and that water can quickly enter the first receiving cavity during the phase of decreasing the buoyancy of the float 5.

[0042] like Figure 1 As shown, the fishing float 5 also includes a float tip 3 and a float foot 4. The float tip 3 is vertically connected to the top of the shell 1. The float tip 3 is made of a hollow rod. The air intake channel includes a perforation. The float tip 3 passes through the perforation and enters the first receiving cavity 22. The float tip 3 and the perforation are interference-fitted. The float foot 4 is vertically connected to the bottom of the shell 1. The float tip 3 is made of a hollow rod, which not only has the advantage of being lightweight, but also connects the first receiving cavity 22 to the external environment. This allows the air intake structure to draw external air into the first receiving cavity 22 through the float tip 3, eliminating the need for an additional air intake pipe. In addition, since the float tip 3 needs to react to fish movements, it is exposed above the water surface, preventing the air intake structure from drawing water into the first receiving cavity 22 during operation. Example

[0043] The difference between this implementation method and Example 1 is that:

[0044] The left shell 10 and the right shell 11 are glued together to form the shell 1. Before actual assembly, glue is applied to the groove 112 or the protrusion 102, and then the left shell 10 and the right shell 11 are aligned and assembled.

[0045] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the present invention, such designs should fall within the protection scope of the present invention.
