Description

Technical Field

[0001] The invention relates to the field of fishing equipment, in particular to an automatic fishing float. Background Art

[0002] Teasing fishing is a fishing method that simulates the dynamics of live bait to attract fish to bite the hook. The core of teasing fishing is to make the bait jump in the water. At present, vertical teasing fishing mainly relies on the angler to stir the fishing rod, and the elasticity of the fishing rod itself is used to move the bait up and down, but this type of fishing method is prone to fatigue; there is also a type of float that can drive the bait to move up and down in the water, without the angler frequently stirring the fishing rod, but this type of float has the following problems: first: the up and down movement of the float in the water is achieved by the propeller pushing the water downward. The propeller needs to be in contact with the water all the time, and the water resistance is large. This driving method has high requirements on the power and endurance of the power source. Batteries are often used to drive propellers, but batteries are relatively large, and sufficient installation space needs to be reserved inside the fishing float, which increases the overall volume of the fishing float, that is, increases the overall weight of the fishing float. In addition, the weight of the battery itself is relatively large, which further increases the overall weight of the fishing float, resulting in a sharp shortening of the battery life of the fishing float (the current battery life of the fishing float is usually less than five hours); second: some fishing floats on the market have propellers that are in direct contact with the water. The propellers will disturb the water flow when working, causing the fishing float to rotate itself, causing the fishing float to entangle with plants or debris on the water surface, affecting the use effect of the fishing float. Summary of the invention

[0003] In order to solve the above-mentioned technical problems, the present invention provides an automatic fishing float. By arranging an air suction mechanism and a liquid discharge structure, the buoyancy of the fish float itself can be changed. By changing the buoyancy of the fish float itself, the purpose of moving the fish float up and down in the water body is achieved. This driving method greatly reduces the requirements for the power source, and the use of a small battery can also provide long-term power supply to the fish float. Moreover, since the weight of the small battery itself is relatively low, the overall weight of the fish float is further reduced, thereby achieving the purpose of enhancing the endurance of the fish float. In addition, by arranging the liquid discharge structure, the water body and the air suction structure are isolated, thereby avoiding direct contact between the exhaust fan and the water body outside the fish float, and achieving the goal that the air suction structure will not drive the fish float itself to rotate when working.

[0004] The technical solution of the present invention is achieved in this way:

[0005] An automatic fishing float comprises an upper shell and a lower shell, the upper shell having a first accommodating chamber, a sealing partition being arranged in the first accommodating chamber, the sealing partition dividing the accommodating chamber into a first cavity and a second cavity arranged in the up-down direction, the upper shell having an exhaust passage, the first cavity being connected to the external environment through the exhaust passage, a drainage structure for discharging liquid in the first cavity being arranged on the side wall of the upper shell; the lower shell being detachably sealed and connected to the upper shell, the lower shell having a second accommodating chamber, the second accommodating chamber and the first accommodating chamber forming a cavity, the cavity being provided with an exhaust structure for sucking air from the external environment into the first cavity.

[0006] In this solution, the outer shell of the fishing float is composed of an upper shell and a lower shell that are sealed and connected. The sealing partition separates the first accommodating cavity of the upper shell into a first cavity and a second cavity. The first cavity and the second cavity are not connected to each other, and the second cavity is connected to the second accommodating cavity to form a cavity. When fishing, the fishing float is located under the water surface. At this time, the first cavity is filled with water, and the fishing float has a tendency to sink; when the air suction structure is running, the water in the first cavity is first discharged from the first cavity through the drainage structure, and then the external air is sucked into the first cavity through the air suction channel. When the water in the first cavity is discharged, the reaction force of the water flow generates an upward thrust on the fish float, and the fish float moves above the water surface under the action of the thrust; when the water in the first cavity is discharged, the external air is sucked into the first cavity, and the buoyancy of the fish float increases sharply at this time, and then continues to move above the water surface; that is, when the air pumping structure is in operation, the fish float will quickly move above the water surface; when the air pumping structure stops operating, the external water flows into the first cavity through the drainage structure, and the overall buoyancy of the fish float decreases at this time, and the fish float sinks into the water. The intermittent operation of the air pumping structure can realize the cyclic up and down jumping of the fish float in the water, and the fish float drives the bait on the hook to jump, which truly simulates the live bait bouncing in the water. dynamics in; wherein a single operation of the air suction structure can complete two actions forward and backward, first discharging the water in the first cavity, and then drawing external air into the first cavity. In the second step, the air suction structure does not need to contact the water. Compared with the propeller that keeps stirring the water to make the float move, the air suction structure mentioned in the present application has lower requirements on the power and endurance of the power source, and can use a small battery, while saving the installation space of the battery (reducing the volume and weight of the float). In addition, the drainage structure of the first cavity isolates the air suction structure from the water outside the float, avoiding direct contact between the exhaust fan and the water outside the float, and achieving the goal that the air suction structure will not drive the float itself to rotate when it is working.

[0007] Preferably, the exhaust mechanism comprises an exhaust fan and a motor structure for driving the exhaust fan to rotate, the exhaust fan is located in the first cavity, and the motor structure is located in the second cavity and the second accommodating cavity. The first cavity is an independent cavity, and when working, the exhaust fan draws air from the external environment into the first cavity.

[0008] Preferably, the sealing partition is arranged horizontally, the motor structure includes a motor, a power supply for the motor, and a circuit board for controlling the motor operation, the motor structure is arranged below the partition, and the power supply is a button battery or a lithium battery. Button batteries have the advantages of stable voltage, small volume and weight, and are suitable for the power source of the fishing float mentioned in this application. In addition, button batteries are more environmentally friendly and reliable than storage batteries, and are suitable for use in water bodies; lithium batteries have the advantages of high energy density and strong environmental adaptability, and are also suitable for the power source of the fishing float mentioned in this application.

[0009] Preferably, a mounting sleeve is provided on the bottom surface of the sealing partition, the motor is located in the mounting sleeve, the output shaft of the motor passes through the sealing partition and enters the first cavity, and the part of the output shaft of the motor that passes through the sealing partition is connected to the exhaust fan. The exhaust fan is separately arranged in the first cavity. This avoids other components occupying the space of the first cavity, and ensures that the first cavity can provide sufficient buoyancy for the fishing float.

[0010] Preferably, the fishing float further comprises a tail and a foot, wherein the tail is vertically connected to the top of the upper shell, the tail is made of a hollow rod, the air extraction channel comprises a perforation, the tail passes through the perforation to enter the first cavity, the tail is interference fit with the perforation, and the foot is vertically connected to the bottom of the lower shell. The tail is made of a hollow rod, which not only has the advantage of light weight, but also can connect the first cavity and the external environment, so that the air extraction structure draws external air into the first cavity through the tail, without the need to set up an additional air intake line; in addition, since the tail needs to respond to fish signals, it is exposed to the water surface, which prevents the air extraction structure from drawing water into the first cavity when working.

[0011] Preferably, the hollow tube is a hollow optical fiber tube or a hollow plastic tube. The hollow tube made of plastic or optical fiber can ensure that the floating tail has the characteristics of high structural strength and light weight.

[0012] Preferably, the drainage structure includes a plurality of drainage channels arranged on the side wall of the upper shell, the drainage channels are arranged downwardly from the inside to the outside, the drainage channels include a liquid inlet and a liquid outlet, and the bottom surface of the liquid outlet is smoothly connected with the bottom surface of the first cavity. The drainage channel is arranged downwardly from the inside to the outside and the bottom surface of the liquid outlet is smoothly connected with the bottom surface of the first cavity. In the stage of increasing the buoyancy of the fish float, it can ensure that the water in the first cavity can be completely discharged; in the stage of reducing the buoyancy of the fish float, it can ensure that the water quickly enters the first cavity, thereby improving the moving efficiency of the fish float.

[0013] Preferably, the plurality of drainage channels are distributed on the side wall of the housing in a circular array with the axis of the upper housing as the center. The plurality of drainage channels are arranged at equal intervals, which increases the stability of the fish float during the drainage process, that is, the fish float itself will not be skewed during the upward movement of the fish float.

[0014] Preferably, the upper shell is also provided with a chamber for enhancing the buoyancy of the shell itself. The chamber provides basic buoyancy for the fish float, so that the fish float can basically float in the water, further reducing the dependence on the power source.

[0015] Preferably, the upper shell and the lower shell are connected by threads, and both the upper shell and the lower shell are made of resin material. The threaded connection has the advantages of easy disassembly, good adaptability and easy processing, and is suitable for the connection between the upper shell and the lower shell.

[0016] The principle and beneficial effects of the present invention using the above technical solution are:

[0017] 1. The air from the external environment is sucked into the first cavity through the air pumping structure, and the liquid in the first cavity is discharged from the drainage channel. At this time, the buoyancy of the fish float increases, and the fish float moves upward; the air pumping structure stops running, and the water flows into the first cavity from the drainage channel again. At this time, the buoyancy of the fish float decreases and it sinks into the water. Compared with the existing driving structure, there is no need for a propeller to directly push the water body, which greatly reduces the demand for power source power, that is, a small battery can meet the long-term endurance of the fish float.

[0018] 2. From the perspective of the use of small batteries, the weight of the small batteries themselves is relatively small, which reduces the weight of the fishing float's air extraction structure; at the same time, the volume of the small batteries is also small, and the installation space requirements are low, which can further reduce the volume of the fishing float shell, that is, reduce the weight of the fishing float shell. In summary, compared with the existing fishing float, the weight of the fishing float mentioned in this application is greatly reduced, and the small battery can not only meet the power requirements of the fishing float, but also ensure the endurance of the fishing float.

[0019] 3. The multiple drainage channels of the upper shell are arranged at equal intervals, which increases the stability of the float during the drainage process, that is, the float itself will not rotate or tilt during the upward movement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0029] The up and down directions mentioned in this embodiment refer to the up and down directions of the height of the fishing float itself; the inside and outside directions refer to the directions approaching and away from the axis of the fishing float.

[0030] The specific implementation methods of the present invention are as follows:

[0031] like Figures 1 to 5As shown, the present invention provides an automatic fishing float, including an upper shell 1 and a lower shell 2, the upper shell 1 has a first accommodating chamber 10, a sealing partition 11 is arranged in the first accommodating chamber 10, and the sealing partition 11 divides the accommodating chamber into a first cavity 101 and a second cavity 102 arranged in the up and down direction, the upper shell 1 is provided with an exhaust channel 12, the first cavity 101 is connected to the external environment through the exhaust channel 12, and a drainage structure 13 for discharging the liquid in the first cavity 101 is provided on the side wall of the upper shell 1; the lower shell 2 is detachably sealed and connected to the upper shell 1, and the lower shell 2 has a second accommodating chamber 21, and the second accommodating chamber 21 is connected to the first accommodating chamber 1 0 constitutes a cavity 3, and the cavity 3 is provided with an exhaust structure 4 for sucking air from the external environment into the first cavity 101. The exhaust mechanism includes an exhaust fan 41 and a motor 42 structure for driving the exhaust fan 41 to rotate. The exhaust fan 41 is located in the first cavity 101, and the motor 42 structure is located in the second cavity 102 and the second accommodating cavity 21. The motor 42 structure includes a motor 42, a power supply for the operation of the power supply machine 42, and a circuit board 44 for controlling the operation of the motor 42. Further, the power supply is a button battery 43. The button battery 43 has the advantages of stable voltage, small volume and weight, and is suitable for the power source of the fishing float 100 mentioned in this application. In addition, the button battery 43 is more environmentally friendly and reliable than the storage battery, and is suitable for use in water bodies. In another implementation scheme of this embodiment, a small lithium battery is used as a power source. The lithium battery has the advantages of high energy density and strong environmental adaptability, and is also suitable for the power source of the fishing float mentioned in this application.

[0032] In this solution, the outer shell of the fishing float 100 is composed of an upper shell 1 and a lower shell 2 which are sealed and connected. The sealing partition 11 divides the first accommodating chamber 10 of the upper shell 1 into a first cavity 101 and a second cavity 102. The first cavity 101 and the second cavity 102 are not connected to each other, and the second cavity 102 is connected to the second accommodating chamber 21 to form a cavity 3. When fishing, the fishing float 100 is connected to the fishing line through the float seat, and the fishing float 100 is located above the fishhook. Usually, the shell of the fishing float 100 is also located under the water surface. At this time, the first cavity is filled with water, and the fishing float has a tendency to sink; when the air pumping structure 4 is in operation, the water in the first cavity 101 is first discharged from the first cavity 101 through the drainage structure 13, and then the external air is sucked into the first cavity 101 through the air pumping channel 12. When the water in the first cavity is discharged, the reaction force of the water flow generates an upward thrust on the fish float 100, and the fish float 100 moves above the water surface under the action of the thrust; when the water in the first cavity 101 is discharged, the external air is sucked into the first cavity 101, and the buoyancy of the fish float 100 increases sharply, and then continues to move above the water surface; that is, when the air pumping structure is in operation, the fish float will move quickly above the water surface; when the air pumping structure 4 stops running, the external water flows into the first cavity 101 through the drainage structure 13, and the overall buoyancy of the fish float 100 decreases, and the fish float 100 sinks into the water. The intermittent operation of the air pumping structure 4 can realize the cyclic up and down movement of the fish float 100 in the water. The fish float 100 drives the bait on the hook to move up and down, which truly simulates the dynamics of the simulated live bait in the water. In this embodiment, the operation time of the air pumping structure 4 is set to 1 second, and the operation interval is 29 seconds. Even if the fishing float is used for 8 hours at a time, the actual working time of the air pumping mechanism is 16 minutes, and the overall power consumption of the fishing float 100 can be fully met by the button battery 43. According to the test results, the fishing float 100 can be used normally for more than ten hours in static water or water with a slow flow rate.

[0033] It can be understood that the exhaust structure can complete two actions during a single operation. First, the exhaust fan 41 stirs the water inside the first cavity 101 and quickly discharges it. At this time, the reaction force of the water flow produces an upward thrust on the fish float 100, and the fish float 100 moves above the water surface. When the water inside the first cavity 101 is discharged, the exhaust fan 41 continues to draw air from the external environment into the first cavity 101. At this time, the buoyancy of the fish float 100 increases, and the fish float 100 continues to move above the water surface. In the above process, the exhaust fan 41 only needs to be in contact with the water body for a short time, and the energy consumption is small. Subsequently, the up and down movement of the fish float 100 is achieved by increasing the buoyancy of the first cavity 101. Compared with the propeller stirring the water body all the time to make the fish float 100 move up, the power and endurance requirements of the power source are lower, and a small battery can be used as the power source. Because the installation space of the small battery is small; correspondingly, the outer shell of the fish float 100 can also be reduced, and the weight of the small fish float 100 is also relatively light, which further increases the endurance of the small battery. In addition, the arrangement of the drainage structure 13 prevents the air suction structure 4 from directly contacting the water body, thereby ensuring that the fishing float 100 does not rotate around its own axis when moving up and down in the water body.

[0034] like Figure 2As shown, in this embodiment, the sealing baffle 11 is arranged horizontally, and a mounting sleeve 14 is arranged on the bottom surface of the sealing baffle 11, and a casing 142 adapted to the motor is arranged inside the mounting sleeve 14, and the motor 42 is installed in the casing 142, and the output shaft 421 of the motor 42 passes through the sealing baffle 11 and enters the first cavity 101, and the output shaft 421 of the motor 42 passes through the sealing baffle 11 and is connected to the exhaust fan 41, in this embodiment, the motor 42 is bonded in the casing 142 by an adhesive, and a sealing gasket 111 is arranged between the output shaft 421 of the motor 42 and the sealing baffle 11, and the sealing gasket 111 is arranged to ensure that the water inside the first cavity 101 does not flow into the second cavity 102. It can be understood that the exhaust fan 41 is arranged separately in the first cavity 101, and it can also avoid other components occupying the space of the first cavity 101, and ensure that the first cavity 101 can provide sufficient buoyancy for the fish float 100. It should be noted that in this embodiment, the installation sleeve 14, the sealing partition 11 and the casing 142 are integrally formed, a card slot 103 is provided on the inner side wall of the first accommodating chamber 10, and a card platform 141 adapted to the card slot 103 is provided on the side wall of the installation sleeve 14. During actual installation, the motor 42 is first fixed in the casing 142 of the installation sleeve 14, at which time the output shaft 421 of the motor 42 passes through the sealing partition 11, and then the exhaust fan 41 is installed on the output shaft 421 of the motor 42, and finally the installation sleeve 14 is inserted into the first accommodating chamber 10 until the card platform 141 is inserted into the card slot 103, and then the card platform 141 is bonded to the card slot 103 using an adhesive. It can be understood that the integral molding of the mounting sleeve 14, the sealing partition 11 and the casing 142 is only a preferred solution of the embodiment. The function of the sealing partition 11 is to separate the first accommodating chamber 10 into the first cavity 101 and the second cavity 102 and to ensure that the first cavity 101 and the second cavity 102 are not connected to each other. The casing 142 is used to install the motor 42; the mounting sleeve 14 and the sealing partition 11 can also be separately arranged. When the mounting sleeve 14 and the sealing partition 11 are separately arranged, the sealing partition 11 is first installed on the mounting sleeve 14, and then the motor 42 is fixed in the mounting sleeve 14, and then the exhaust fan 41 is connected to the output shaft 421 of the motor 42, and finally the mounting sleeve 14 and the sealing partition 11 are installed in the first accommodating chamber 10. Whether the mounting sleeve 14, the sealing partition 11 and the casing 142 are separated is selected according to different settings according to actual conditions, and there is no restriction here.

[0035] like Figure 1 and Figure 2As shown, the fishing float 100 also includes a floating tail 5 and a floating foot 6. The floating tail 5 is vertically connected to the top of the upper shell 1. The floating tail 5 is made of a hollow rod body. The air extraction channel 12 includes a perforation 16. The floating tail 5 passes through the perforation 16 to enter the first cavity 101. The floating tail 5 and the perforation 16 are interference fit. The floating foot 6 is vertically connected to the bottom end of the lower shell 2. The floating tail 5 is made of a hollow rod, which not only has the advantage of light weight, but also can connect the first cavity 101 and the external environment, so that the air extraction structure 4 sucks the external air into the first cavity 101 through the floating tail 5, without the need to set up an additional air intake pipeline. In addition, since the floating tail 5 needs to respond to the fish flood, it itself is exposed to the water surface, which avoids the air extraction structure 4 from sucking water into the first cavity 101 when working. In this embodiment. The hollow tube is a hollow optical fiber tube or a hollow plastic tube. The hollow tube made of plastic or optical fiber can ensure that the floating tail 5 has the characteristics of high structural strength and light weight.

[0036] like Figure 1 , Figure 2 as well as Figure 4As shown, the drainage structure 13 includes a plurality of drainage channels 131 arranged on the side wall of the upper shell 1, and the drainage channels 131 are arranged downwardly from the inside to the outside, and the drainage channels 131 include a liquid inlet 1311 and a liquid outlet 1312, and the bottom surface of the liquid outlet 1312 is smoothly connected with the bottom surface of the first cavity 101. The drainage channel 131 is arranged downwardly from the inside to the outside, and the bottom surface of the liquid outlet 1312 is smoothly connected with the bottom surface of the first cavity 101. In the stage of increasing the buoyancy of the fishing float 100, it can ensure that the water in the first cavity 101 is quickly and completely discharged; in the stage of reducing the buoyancy of the fishing float 100, it can ensure that the water quickly enters the first cavity 101, thereby improving the movement efficiency of the fishing float. At the same time, the bottom surface of the liquid outlet 1312 is smoothly connected with the bottom surface of the first cavity 101 to reduce the resistance caused by water and reduce the power consumption of the air pumping structure 4. Specifically, when the air from the external environment enters the first cavity 101, the water in the first cavity 101 is discharged along the liquid outlet 1312 of the drainage channel 131, and the fish float 100 moves upward. In the process of the fish float 100 moving upward, the residual water in the first cavity 101 is further discharged from the liquid outlet 1312 of the drainage channel 131; when the air pumping structure 4 stops running, the fish float 100 falls back into the water body. At this time, when the water in the water body enters the first cavity 101, the water enters the first cavity 101 along the liquid inlet 1311 of the drainage channel 131. At this time, the buoyancy of the fish float 100 is sharply reduced, further accelerating the falling speed of the fish float 100; and also increasing the amplitude of the up and down movement of the fish float 100. In this embodiment, a plurality of drainage channels 131 are distributed on the side wall of the housing in a circular array with the axis of the upper housing 1 as the center. The plurality of drainage channels 131 are arranged at equal intervals. When the first cavity 101 is draining water, the upper shell 1 is subjected to uniform force as a whole, thereby increasing the stability of the fishing float 100 during drainage, that is, the fishing float 100 itself will not be skewed during the upward movement.

[0037] like Figure 2 As shown, the upper shell 1 is also provided with a chamber 15 for enhancing the buoyancy of the shell itself. The chamber 15 provides basic buoyancy for the fishing float 100, so that the fishing float 100 can basically float in the water, further reducing the dependence on the power source. It should be noted that the role of the chamber 15 is to provide basic buoyancy for the fishing float 100. One or more chambers 15 can be provided, and there is no limitation here. The appropriate number and arrangement of chambers are selected according to actual needs.

[0038] The upper shell 1 and the lower shell 2 are connected by threads, and both the upper shell 1 and the lower shell 2 are made of resin material. The threaded connection has the advantages of easy disassembly, good adaptability and easy processing, and is suitable for the connection between the upper shell 1 and the lower shell 2. After the upper shell 1 and the lower shell 2 are connected, they have good sealing performance, so that the second cavity 102 and the second accommodating cavity 21 form a whole sealed cavity, which ensures that the motor structure will not come into contact with water and prolongs the service life of the motor structure. It should be noted that the internal structure of the upper shell 1 provided with the chamber 15 is complex and is not suitable for mold production; in this embodiment, the upper shell 1 and the lower shell 2 are both produced by three-dimensional printing of low-density photocurable resin; the low-density photocurable resin can ensure that the weight of the upper shell 1 and the lower shell 2 is small.

[0039] The present invention and its embodiments are described schematically above, and the description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. Therefore, if a person skilled in the art is inspired by it and designs a structural method and an embodiment similar to the technical solution without creativity without departing from the purpose of the invention, they shall all fall within the protection scope of the present invention.
