Description

Technical Field

[0001] The present invention relates to the field of fishing gear, and in particular to a visual fishing float and an information feedback method for the fishing float. Background Art

[0002] Fishing is a multifaceted activity, a popular sport and leisure pursuit in modern society. With the advancement of technology, many intelligent fishing floats have become available on the market. These floats integrate cameras, gravity sensors, and other features. The cameras can monitor the feeding activity of underwater fish, while the gravity sensors convert changes in gravity when a fish bites into electrical signals, controlling the float's internal circuitry and causing the color of the tail to change. When a fish bites, the gravity sensor activates, causing the tail to change color, alerting the angler that a bite has occurred and the need to reel in the fish. However, these existing intelligent fishing floats lack stability. For example, in strong winds and waves, the wind and waves can cause the float to vibrate up and down, easily generating erroneous signals to reel in the fish.

[0003] Therefore, it is necessary to provide a visual fishing float and an information feedback method of the fishing float to solve the above technical problems. Summary of the Invention

[0007] In the present invention, the magnetic float includes a float box and a magnetic block. The magnetic block is arranged in the float box, and the volume of the magnetic block is smaller than the volume of the float box.

[0009] Furthermore, a guide bar is provided on the inner wall of the open cavity along the length direction of the visual fishing float, and first sliding grooves for sliding connection with the guide bar are provided on both sides of the box body.

[0010] Furthermore, the open cavity penetrates the shell in a radial direction of the shell to form an open opening, and a baffle is provided on the open opening. The baffle includes a plurality of baffles extending along a wave curve on different horizontal lines.

[0011] Furthermore, a limit plate is provided on the inner wall of the open cavity, and two limit plates are provided on both sides of each guide rail, and the limit plates are in sliding positioning contact with the side surfaces of the floating block box;

[0016] Furthermore, the center of gravity of the stopper is biased toward the magnetic float, so that the stopper deflects toward the end closer to the magnetic float, the buoyancy of the end of the stopper away from the magnetic float is greater than the buoyancy of the end of the stopper close to the magnetic float, and when the stopper is located at the end of the slide rail away from the Hall sensor, only the end of the stopper close to the magnetic float intersects the sliding track of the magnetic float;

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0033] Directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only used with reference to the directions of the drawings. The directional terms used are used to illustrate and understand the present invention, and are not used to limit the present invention.

[0034] The terms "first" and "second" in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be used as a limitation on the order of precedence.

[0035] In the present invention, unless otherwise expressly specified or limited, terms such as "mounted," "connected," "connect," and "fixed" should be understood broadly. For example, connection can be a detachable connection or an integral structural connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be internal communication between two components or an interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0036] The stability of the intelligent fishing float in the existing technology is not high enough. For example, when the wind and waves are strong, the wind and waves push the fishing float up and down and shake it, which easily forms an erroneous rod-lifting signal.

[0037] The following is a first embodiment of a visual fishing float provided by the present invention that can solve the above technical problems.

[0038] Please refer to Figure 1 and Figure 2 ,in Figure 1 Schematic diagram of the structure of the first embodiment of the visual fishing float of the present invention. Figure 2 It is a cross-sectional view of a first embodiment of the visual fishing float of the present invention.

[0039] In the figures, structurally similar elements are denoted by the same reference numerals.

[0040] This embodiment provides a visual fishing float, which includes a housing 11 , a magnetic float 13 , a control module 14 , and a battery 15 , a camera 16 , an acceleration sensor, and a Hall sensor 17 electrically connected to the control module 14 .

[0041] The housing 11 is provided with a closed inner cavity, and the middle of the housing 11 is provided with an open cavity 113 communicating with the external space. Figure 2 The upper end and the lower end of the open cavity 113 are both closed inner cavities, and the open cavity 113 and the closed inner cavity are sealed and isolated.

[0042] The camera 16 is set at one end of the shell 11 to shoot toward the external space. The control module 14, battery 15, and acceleration sensor are all set in the closed inner cavity. The magnetic float 13 is set in the open cavity 113. The Hall sensor 17 is set in the closed inner cavity near the open cavity 113 to detect the magnetic field of the magnetic float 13. When the magnetic float 13 is close to the Hall sensor 17, the detected magnetic field is stronger.

[0043] When in use, the lower end of the shell 11 is immersed in water, and there will be water in the open cavity 113. The magnetic float 13 floats in the open cavity 113. When there are strong winds and waves, the shell 11 shakes up and down with the wind and waves, and the water in the open cavity 113 will also fluctuate synchronously. The magnetic float 13 and the shell 11 will shake up and down, and the relative position relationship between the magnetic float 13 and the Hall sensor 17 in the shell 11 will not change much, so it can distinguish whether it is a fish biting the hook or the wind and waves that cause the float to move. The working stability is high and it is not easy to generate erroneous rod-lifting signals.

[0044] Please refer to Figure 3 In this embodiment, the magnetic float 13 includes a float box and a magnet 133. The magnet 133 is arranged in the float box. The volume of the magnet 133 is smaller than the volume of the float box. The excess volume in the float box can make the magnetic float 13 float on the water.

[0045] Among them, the floating block box includes a box body 131 and a cover body 132. A receiving groove for installing the magnetic block 133 is provided on the inner side of the cover body 132. A fixing column 1312 is provided in the box body 131. When the box body 131 and the cover body 132 are packaged and connected, the fixing column 1312 restricts the magnetic block 133 in the receiving groove. The cover body 132 is located on the side of the box body 131 close to the Hall sensor 17.

[0046] An annular clamping groove is provided on the inner circumferential side wall of the box body 131, an annular clamping strip 1321 is provided on the outer circumferential side wall of the cover body 132, a sealing groove 1311 is provided on the inner circumferential side wall of the box body 131, and a sealing ring is provided in the sealing groove 1311. When the clamping strip 1321 is engaged with the clamping groove, the cover body 132 is in contact with the sealing ring 134 to ensure the sealing of the internal space of the floating block box.

[0047] Please refer to Figure 2 A guide bar 18 is provided on the inner wall of the open cavity 113 along the length direction of the visual fishing float, and a first sliding groove for sliding connection with the guide bar 18 is provided on both sides of the box body 131, so that the magnetic float 13 can fluctuate stably up and down in the open cavity 113, and the magnetic float 13 will not fluctuate left and right relative to the Hall sensor 17, and the magnetic field detected by the Hall sensor 17 is more regular.

[0048] In this embodiment, the open cavity 113 passes through the shell 11 in the radial direction of the shell 11 to form an open mouth, and a baffle 12 is provided on the open mouth. The baffle 12 includes a plurality of baffles 1221 extending along the wave curve on different horizontal lines, which has a certain filtering effect on wind and waves, preventing the waves from excessively driving the magnetic float 13 to move, and preventing the Hall sensor 17 from generating erroneous signals when detecting the magnetic field of the magnetic float 13. However, when the fish bites the hook and drags the float underwater, the water can smoothly pass through the gap between the baffles 1221 and enter the open cavity 113. The water pushes the magnetic float 13 close to the Hall sensor 17, so that the Hall sensor 17 detects a stronger magnetic field.

[0049] Furthermore, a limit plate 19 is provided on the inner wall of the open cavity 113, and two limit plates 19 are provided on both sides of each guide bar 18. The limit plates 19 are in sliding contact with the side of the float box, further improving the stability of the up and down shaking of the magnetic float 13.

[0050] Please refer to Figure 2 The shell 11 is divided into a first shell portion 111 and a second shell portion 112 along the axial direction. The first shell portion 111 and the second shell portion 112 are connected to form a closed inner cavity. Before the first shell portion 111 and the second shell portion are connected, the control module 14, the camera 16, the Hall sensor 17 and other components can be installed.

[0051] A first cylinder 1211 is provided in the first shell 111, and a second cylinder 1221 is provided in the second shell 112. The first cylinder 1211 and the second cylinder 1221 are connected to form an open cavity 113. Figure 1 From the viewing direction, there is space on the left and right sides of the first cylinder 1211 and the second cylinder 1221, which can connect the closed inner cavities of the upper and lower ends of the shell 11.

[0052] Here, the baffles 12 on both sides are respectively a first baffle 121 and a second baffle 122. Optionally, the first baffle 121 and the adjacent guide rail 18 and limit plate 19 are integrally formed with the first shell 111, and the second baffle 122 and the adjacent limit plate 19 are integrally formed. The second baffle 122 and the second shell 112 are detachably connected, and the limit plate 19 adjacent to the second baffle 122 are integrally formed with the second baffle 122, and the guide rail 18 adjacent to the second baffle 122 are integrally formed with the second shell 112. After the fishing float has been used for a long time, some dirt and debris may accumulate in the open cavity 113, which may affect the movement of the magnetic float 13. In this case, the second baffle 122 can be removed to clean the open cavity 113.

[0053] Of course, it is conceivable that if the influence of dirt and debris is not considered, the second baffle 122 and the guide bar 18 and the limit plate 19 close to it can be an integrally formed structure with the second shell 112, so that the first shell 111 and the second shell 112 are symmetrical structures with low manufacturing costs.

[0054] Please refer to Figure 4 The detachable structure of the second baffle 122 and the second shell 112 is specifically as follows. A connecting groove is provided on the inner wall of the second cylinder 1221. The second baffle 122 is sleeved in the second cylinder 1221. An elastic plate 191 is provided at one end of the limiting plate 19 near the second baffle 122 for engaging with the connecting groove. The end of the elastic plate 191 away from the second baffle 122 is connected to the limiting plate 19. The end of the elastic plate 191 near the second baffle 122 is provided with a connecting block 192 for engaging with the connecting groove. An extension bar 193 is provided on one side of the elastic plate 191. The gap between the extension bar 193 and the baffle 1221 is opposite. By squeezing the extension bar 193, the elastic plate 191 can be moved away from the connecting groove, thereby disconnecting the connecting block 192 from the connecting groove. The extension bar 193 is well concealed, not easily touched by mistake, and is easy to assemble and disassemble.

[0055] Please refer to Figure 8 The present invention also includes a method for feeding back information of a fishing float, which uses the above-mentioned visual fishing float. It should also be noted that the control module 14 is provided with a wireless module for communicating with the user terminal. The method for feeding back information of a fishing float includes the following steps:

[0056] S11: Start, the control module 14 establishes a communication connection with the user terminal through the wireless module. The control module 14 is preset with a magnetic field signal trigger value and an acceleration signal trigger value. The control module 14 obtains the magnetic field signal value of the Hall sensor 17 and the acceleration signal value of the acceleration sensor.

[0057] S12: Control module 14 compares the magnetic field signal value with the magnetic field signal trigger value. If the magnetic field signal value is less than the magnetic field signal trigger value, it indicates that the magnetic float 13 is far from the Hall sensor 17, there is still a lot of water in the open cavity 113, and the fishing float has not been pulled underwater. In this case, the process jumps to step S11. If the magnetic field signal value is greater than or equal to the magnetic field signal trigger value, it indicates that the magnetic field detected by the Hall sensor 17 is strong, the magnetic float 13 is close to the Hall sensor 17, the fishing float has been pulled underwater, and the water has submerged the open cavity 113. In this case, the process jumps to step S13.

[0058] S13: The control module 14 compares the acceleration signal value and the acceleration signal trigger value. If the acceleration signal value is less than the acceleration signal trigger value, the control module 14 sends a warning signal to the user terminal. At this time, the hook may be hooked on a foreign object, and as the water flow fluctuates, the distance between the float and the foreign object gradually increases, causing the open cavity 113 to be immersed in water. Or it may be that the fish has bitten the hook and is moving slowly. The warning signal is used to prompt the customer to confirm the situation by themselves and perform corresponding operations. If the acceleration signal value is greater than or equal to the acceleration signal trigger value, it is highly likely that the fish has bitten the hook and quickly pulled the float. In this case, the control module 14 sends a rod-lifting signal to the user terminal.

[0059] The above information feedback method of the fishing float describes the working principle of the visual fishing float of this embodiment.

[0060] Please refer to Figure 5-Figure 7 The following is a second embodiment of a visual fishing float provided by the present invention that can solve the above technical problems. The main difference between this embodiment and the first embodiment is the provision of a stopper that can float on the water surface. The other structures are the same, and the same parts are not described in detail in this embodiment.

[0061] This embodiment provides a visual fishing float, which includes a housing 11 , a magnetic float 13 , a control module 14 , and a battery 15 , a camera 16 , an acceleration sensor, and a Hall sensor 17 electrically connected to the control module 14 .

[0062] The housing 11 is provided with a closed inner cavity, and the middle of the housing 11 is provided with an open cavity 113 communicating with the external space. Figure 2 The upper end and the lower end of the open cavity 113 are both closed inner cavities, and the open cavity 113 and the closed inner cavity are sealed and isolated.

[0063] The camera 16 is set at one end of the shell 11 to shoot toward the external space. The control module 14, battery 15, and acceleration sensor are all set in the closed inner cavity. The magnetic float 13 is set in the open cavity 113. The Hall sensor 17 is set in the closed inner cavity near the open cavity 113 to detect the magnetic field of the magnetic float 13. When the magnetic float 13 is close to the Hall sensor 17, the detected magnetic field is stronger.

[0064] When in use, the lower end of the shell 11 is immersed in water, and there will be water in the open cavity 113. The magnetic float 13 floats in the open cavity 113. When there are strong winds and waves, the shell 11 shakes up and down with the wind and waves, and the water in the open cavity 113 will also fluctuate synchronously. The magnetic float 13 and the shell 11 will shake up and down, and the relative position relationship between the magnetic float 13 and the Hall sensor 17 in the shell 11 will not change much, so it can distinguish whether it is a fish biting the hook or the wind and waves that cause the float to move. The working stability is high and it is not easy to generate erroneous rod-lifting signals.

[0065] In this embodiment, a groove 22 is formed on the inner wall of the open cavity 113 near the Hall sensor 17. A slide rail 23 is provided on the inner bottom surface of the groove 22. A stopper 21, capable of floating on the water surface, is slidably connected to the slide rail 23. The stopper 21 may be made of foam or a hollow structure. Since the magnetic float 13 in this embodiment is circular in shape and the inner wall of the open cavity 113 is also circular, the groove 22 is necessary to allow the stopper 21 to slide along the slide rail 23 into the groove 22, allowing the stopper 21 to move away from the magnetic float 13 and avoid the magnetic float 13.

[0066] The slide rail 23 is tilted relative to the length of the visual fishing float. When the stopper 21 is located at the end of the slide rail 23 away from the Hall sensor 17, the stopper 21 intersects the sliding path of the magnetic float 13. When the stopper 21 is located at the end of the slide rail 23 closer to the Hall sensor 17, the stopper 21 and the sliding path of the magnetic float 13 are separated by a set distance. When there is insufficient water in the open cavity 113, the stopper 21 slides under its own weight to the end of the slide rail 23 away from the Hall sensor 17. As the magnetic float 13 floats upward with the waves, it can collide with the stopper 21. The direction of the collision is inconsistent with the sliding direction of the stopper 21. This provides a certain degree of resistance to the magnetic float 13, preventing the magnetic float 13 from being pushed too close to the Hall sensor 17 by the waves when the open cavity 113 is not fully submerged, thereby generating an erroneous magnetic field signal.

[0067] Furthermore, the center of gravity of the stopper 21 is biased toward the magnetic float 13, so that the stopper 21 deflects toward the end close to the magnetic float 13. The buoyancy of the end of the stopper 21 away from the magnetic float 13 is greater than the buoyancy of the end of the stopper 21 close to the magnetic float. When the stopper 21 is located at the end of the slide rail 23 away from the Hall sensor 17, only the end of the stopper 21 close to the magnetic float 13 intersects with the sliding track of the magnetic float 13, that is, the magnetic float 13 will only collide with the end of the magnetic float 13. Figure 6 The right end of the middle block 21, and the center of gravity of the block 21 is biased towards the magnetic float 13, so that after the collision, the impact force causes the block 21 to tend to rotate more, and it is difficult for the block 21 to slide along the slide rail 23, thereby increasing the blocking force formed by the block 21 on the floating of the magnetic float 13.

[0068] Furthermore, a slider 24 is provided on one side of the stopper 21. A second slide groove for connecting to the slide rail 23 is provided on the slide groove 24. The second slide groove is inclined relative to the slide rail 23. The width of the second slide groove is greater than the width of the slide rail 23. The slider 24 is larger than but does not separate from the slide rail 23. Elastic rubber blocks 241 are embedded in the highest and lowest ends of the second slide groove. Figure 7Point A is the highest end, and the position indicated by 241 is the lowest end. When the magnetic float 13 hits and squeezes the stopper 21, the elastic rubber block contacts the slide rail 23, and the friction is large, making it difficult for the stopper 21 to slide along the slide rail 23, thereby increasing the blocking force formed by the stopper 21 on the floating of the magnetic float 13.

[0069] When the stopper 21 is not subjected to external forces, its center of gravity is biased toward the magnetic float 13. The ends of the second chute without the elastic rubber block are more in contact with the rail 23. The slider 24 is made of plastic or metal, resulting in low friction, allowing the stopper 21 to slide easily along the rail 23. Furthermore, when the open cavity 113 is almost completely submerged in water, the buoyancy of the end of the stopper 21 away from the magnetic float 13 is greater than the buoyancy of the end of the stopper 21 closer to the magnetic float. This causes the stopper 21 to deflect toward the magnetic float 13, making it less likely that the elastic rubber block will contact the rail 23. Simultaneously, the water within the open cavity 113 pushes the stopper 21 upward, causing it to slide along the rail 23 and avoid the magnetic float 13. This allows the magnetic float 13 to successfully reach a position very close to the Hall effect sensor 17, allowing the magnetic field signal sensed by the Hall effect sensor 17 to provide feedback indicating the float's descent.

[0070] The main operating principles of this embodiment are consistent with those of the first embodiment and will not be elaborated upon here. The main difference lies in the inclusion of a stopper 21. When the open cavity 113 is not fully submerged, the stopper 21 prevents the magnetic float 13 from being pushed too close to the Hall sensor 17 by waves, potentially generating an erroneous magnetic field signal. When the open cavity 113 is nearly completely submerged, the buoyancy of the end of the stopper 21 away from the magnetic float 13 is greater than the buoyancy of the end of the stopper 21 closer to the magnetic float 17, as well as the buoyancy of the stopper 21 itself. This allows the stopper 21 to easily slide along the guide rail 23, avoiding the magnetic float 13 and eliminating its obstruction. This allows the magnetic float 13 to successfully reach a position very close to the Hall sensor 17, allowing the magnetic field signal sensed by the Hall sensor 17 to provide feedback on the float's descent.

[0071] The visual fishing float of the present invention sets a magnetic float in an open cavity. When there are strong winds and waves, the magnetic float and the shell will shake up and down, and the relative position relationship between the magnetic float and the Hall sensor will not change much. Therefore, the magnetic field signal of the Hall sensor can be used to distinguish whether it is a fish biting the hook or wind and waves that cause the fishing float to move. The working stability is high and it is not easy to generate erroneous rod-lifting signals.

[0072] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
