Abstract
Description
[Technical Field]
[0001] This utility model relates to fishing floats with or without signaling devices, particularly to fishing floats with signaling devices, and especially to fishing floats with luminous devices. [Background Technology]
[0002] With the improvement of people's living standards, fishing has not only become a popular leisure activity for middle-aged and elderly people, but is also increasingly favored by many young people. Anglers usually need to use floats when fishing. The main functions of the float are to test the depth of the fishing water, transmit information about fish bites, and control the position of the hook and rig in the water.
[0003] Existing luminous float structures, such as the fishing float patent filed by the inventor on June 15, 2020 (application number: 202021097373.2), disclose a fishing float comprising an upper float body, a lower float body, and a battery. The upper float body includes an upper float shell, a float tip fixed to the upper part of the upper float shell, and a light-emitting diode (LED). The upper float shell has an upper cavity that can accommodate the LED and the battery. The lower float body includes a lower float shell and a float foot fixed to the lower part of the lower float shell. The LED is disposed in the upper cavity of the upper float shell, and the battery is detachably disposed in the upper cavity of the upper float shell. The battery and the LED are detachably electrically connected together. The upper and lower float shells are detachably sealed together. This fishing float has advantages such as simple structure, convenient installation and disassembly, large buoyancy, long battery life, and low cost. However, this fishing float has the following shortcomings:
[0004] First, because the light-emitting diode is located in the upper cavity of the upper float shell, the light-emitting diode transmits light to the hollow float tail and then emits it. The brightness inside the float tail is insufficient, and the light from the float tail is not conspicuous enough.
[0005] Second, sometimes the battery has poor contact, causing the LED to light up intermittently.
[0006] Third, the internal thread is located inside the lower part of the upper floating shell, which makes the structure of the upper floating shell slightly more complicated, and it is slightly more difficult to machine the internal thread on the inner wall of the upper floating shell.
[0007] Fourth, the upper float shell is generally made of plastic, and the connection between the upper float shell and the float tip is prone to cracking. [Utility Model Content]
[0008] The technical problem to be solved by this utility model is to avoid the shortcomings of the above-mentioned prior art and provide a fishing electronic float with the advantages of simple structure, bright and eye-catching internal brightness of the float tip, convenient installation and disassembly, good battery contact, float shell not easy to crack and low cost.
[0009] The technical solution adopted by this utility model to solve the aforementioned technical problem is:
[0010] An electronic fishing float is provided, comprising a first float body, a second float body, and a battery. The first float body includes a first float shell, a float tip fixed to the tail of the first float shell, and a first circuit board. The first float shell has a first cavity inside that can accommodate the first circuit board and the battery. The tail of the first float shell has a first axial through hole communicating with the first cavity. The second float body includes a second float shell and a float foot fixed to the tail of the second float shell. The first circuit board is disposed in the first cavity of the first float shell, and the battery is detachably disposed in the first cavity of the first float shell. The battery is detachably electrically connected to the first circuit board. The first float shell and the second float shell are detachably sealed together. One end of the float tip is open and has an internal cavity. The first float body also includes a flexible circuit board located in the internal cavity of the float tip and electrically connected to the first circuit board. The flexible circuit board has at least one light-emitting diode.
[0011] The free end of the flexible circuit board is close to or in contact with the bottom of the internal cavity of the drift tail.
[0012] The cavity of the drift tail is filled with a solidified filler that fixes the flexible circuit board.
[0013] The first float body also includes a compressible elastic element disposed within a first cavity of the first float shell and located between the first circuit board and the battery.
[0014] The elastic element is a spring.
[0015] The battery is interference-fitted with the first cavity; after the battery is inserted into the first cavity and the elastic element is compressed into place, the elastic force of the elastic element cannot move the battery.
[0016] After the battery is inserted into the first cavity and the elastic element is compressed into place, a portion of the battery still protrudes outside the first floater shell.
[0017] The drift tail is a hollow tube made of glass fiber columnar material.
[0018] The first float body also includes a fixing sleeve made of metal material and having a second axial through hole. The tail of the first float shell is provided with a first axial through hole that communicates with the first cavity. The fixing sleeve is sealed and fixed in the first axial through hole of the first float shell, and the float tail is sealed and fixed in the second axial through hole of the fixing sleeve.
[0019] The second float body also includes an internally threaded nest with a third axial through hole, the third axial through hole having an internal thread; the second float shell has a second cavity inside, the internally threaded nest being fixed in the second cavity of the second float shell; the first float shell has a first cylindrical portion at one end facing the second float shell, the first cavity passing through the first cylindrical portion, the first cylindrical portion having an external thread adapted to the internal thread; the first float shell and the second float shell can be detachably fixed together by means of the internal thread and the external thread.
[0020] Compared with existing technologies, the beneficial effects of this utility model of electronic fishing float are as follows:
[0021] 1. This utility model has a flexible circuit board directly installed inside the internal cavity of the float, and at least one light-emitting diode is installed on the flexible circuit board. In other words, a light-emitting diode is directly installed inside the internal cavity of the float, so that the brightness inside the float is bright and eye-catching enough.
[0022] Second, the inner cavity of the float is also filled with solidified filler to fix the flexible circuit board, so that the flexible circuit board will not shake in the inner cavity of the float and the service life of the flexible circuit board is guaranteed.
[0023] Third, this utility model detachably houses the battery inside the first float shell, and the battery is also detachably electrically connected to the first circuit board. The first float shell and the second float shell are also detachably and sealed together. In this way, when the fishing electronic float of this utility model is not in use, the first float shell and the second float shell can be separated at any time, and the battery can also be separated from the first circuit board at any time. The battery can be removed from the first float shell at any time, which can better protect the battery and extend its service life. Moreover, the first float body also includes a compressible elastic element, which is set in the first cavity of the first float shell and located between the first circuit board and the battery. With the compressible elastic element, a certain length of elastic operating space can be reserved in the internal space of the first cavity, which can ensure good battery electrical contact performance.
[0024] Fourth, since the battery and the first cavity are interference fit, that is, tight fit, after the battery is inserted into the first cavity and the elastic element is compressed into place, the elastic force of the elastic element cannot move the battery, which can further ensure the reliability of the battery after good electrical contact.
[0025] 5. To facilitate processing and make installation and disassembly easier, a separate nest with internal threads is provided. That is, the second float body also includes an internally threaded nest fixed in the second cavity of the second float shell. The first float shell has a first cylindrical part at one end facing the second float shell, and the first cylindrical part has an external thread that matches the internal thread. With the help of the internal thread and the external thread, the first float shell and the second float shell can be detachably fixed together.
[0026] VI. In order to prevent the connection between the first float shell and the float tip from cracking, the float tip is sealed and fixed to the first float shell by a fixing sleeve made of metal material.
[0027] 7. The entire structure and process of the electronic fishing float are very simple, making it easy to manufacture and install, and the cost is low.
[0028] In summary, the present invention provides an electronic fishing float with advantages such as simple structure, bright and eye-catching internal brightness of the float tip, convenient installation and disassembly, good battery contact, float shell that is not easily cracked, and low cost.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings.
[0035] Special note: To avoid ambiguity, the names of the upper float body, lower float body, upper float shell, and lower float shell in the fishing float with prior art application number 202021097373.2 are respectively referred to as the first float body, second float body, first float shell, and second float shell in this utility model.
[0036] See Figures 1 to 3An electronic fishing float includes a first float body 10, a second float body 20, and a battery 30. The first float body 10 includes a first float shell 11, a float tip 12 fixed to the tail of the first float shell 11, and a first circuit board 13. The first float shell 11 has a first cavity 111 that can accommodate the first circuit board 13 and the battery 30. The tail of the first float shell 11 has a first axial through hole 112 that communicates with the first cavity 111. The second float body 20 includes a second float shell 21 and a float foot 22 fixed to the tail of the second float shell 21. The first circuit board 13 is disposed in the first cavity 111 of the first float shell 11, and the battery 30 is detachably disposed in the first cavity 111 of the first float shell 11. The battery 30 is detachably electrically connected to the first circuit board 13. In this way, when the electronic fishing float is not in use, the battery 30 can be separated from the first circuit board 13 at any time, which can better protect the battery 30 and extend its service life. Lifespan; The first float shell 11 and the second float shell 21 are detachably sealed together, so that when the electronic fishing float of this utility model is not in use, the first float shell 11 and the second float shell 21 can be separated at any time, and the battery 30 in the first cavity 111 of the first float shell 11 can be taken out, which can better protect the battery 30 and extend the service life of the battery 30, and the replacement of the battery 30 is also convenient; The float tip 12 is open at one end and has an internal cavity 121. The float tip 12 is generally a hollow tube made of light-transmitting material (the top is closed). For example, the float tip 12 is a hollow tube of light-transmitting glass fiber columnar material (the top is closed). The float tip 12 adopts a glass fiber columnar structure. Glass fiber has a certain hardness, which can effectively prevent the float tip from bending and deforming; The first float body 10 also includes a flexible circuit board 14. The flexible circuit board 14 is located in the internal cavity 121 of the float tip 12 and is electrically connected to the first circuit board 13. The flexible circuit board 14 is provided with at least one light-emitting diode (not shown). Generally speaking, The light-emitting diodes (LEDs) are positioned on the section of the float tail 12 that protrudes from the first float shell 11 onto the flexible circuit board 14. The number of LEDs is determined based on the length of the float tail 12 protruding from the first float shell 11 and the required brightness. The flexible circuit board 14 can be directly connected to the first circuit board 13 inside the first cavity 111 by passing through the first axial through hole 112 of the first float shell 11, or an electrical connection wire can be used to pass through the first axial through hole 112 of the first float shell 11 to electrically connect the flexible circuit board 14 and the first circuit board 13.
[0037] See Figure 3 The free end of the flexible circuit board 14 is close to or in contact with the bottom of the internal cavity 121 of the floating tail 12. For easier viewing, in Figure 3 The Chinese text specifically uses a red line to represent the flexible circuit board 14.
[0038] See Figure 3The cavity 121 of the floating tail 12 is filled with a solidified filler that fixes the flexible circuit board 14. This solidified filler is translucent. Figure 3 The solidified filler (not marked) is represented by small granular dots inside the inner cavity 121 of the middle float 12. For example, the solidified filler can be a type of silicone.
[0039] See Figure 2 and Figure 3 The first float body 10 also includes a compressible elastic element 19, which is disposed within the first cavity 111 of the first float shell 11 and located between the first circuit board 13 and the battery 30. The compressible elastic element 19 allows for a certain length of flexible operating space within the first cavity 111, ensuring good electrical contact performance of the battery 30. The battery 30 is shaped similarly to a standard AAA battery, and its electrical connection portion 31 has a certain length for easy detachable electrical connection.
[0040] See Figure 2 and Figure 3 The elastic element 19 is a spring.
[0041] See Figure 2 , Figure 4 and Figure 5 To facilitate processing, installation, and disassembly, a separate internally threaded nest is provided. Specifically, the second float body 20 also includes an internally threaded nest 29 with a third axial through hole 291, the third axial through hole 291 having an internal thread 2911 inside. The second float shell 21 has a second cavity 211 inside, and the internally threaded nest 29 is fixed within the second cavity 211 of the second float shell 21. The first float shell 11 has a first cylindrical portion 115 at one end facing the second float shell 21, the first cavity 111 penetrating the first cylindrical portion 115, and the first cylindrical portion 115 having an external thread 1151 adapted to the internal thread 2911. With the help of the internal thread 2911 and the external thread 1151, the first float shell 11 and the second float shell 21 can be detachably fixed together. The first cylindrical portion 115 on the first float shell 11 has another function: the first cavity 111 inside the first cylindrical portion 115 can be used as a cavity to accommodate the first circuit board 13, the elastic element 19 and the battery 30, etc., so that the battery compartment is not needed, saving a part.
[0042] See Figure 3The battery 30 and the first cavity 111 are in an interference fit, i.e., a tight fit. Multiple ribs (not shown), such as four ribs, can be provided on the inner wall of the first cavity 111 to act like claws and elastically hold the battery 30 in place. The multiple ribs also prevent the battery 30 from loosening after repeated insertion and removal, ensuring a good interference fit even after multiple insertions and removals. After the battery 30 is inserted into the first cavity 111 and compresses the elastic element 19 into place, the elastic force of the elastic element 19 cannot move the battery 30, thus further ensuring the reliability of the battery 30 after good electrical contact.
[0043] See Figure 3 To facilitate the subsequent removal and installation of the battery 30, after the battery 30 is inserted into the first cavity 111 and the elastic element 19 is compressed into place, a portion of the battery 30 still protrudes outside the first cylindrical portion 115 of the first float shell 11.
[0044] See Figure 1 To make the float tip brighter and more eye-catching and easier for anglers to see, the float tip 12 is coated with two different colors of alternating float tips.
[0045] See Figure 1 To make the float tip brighter and more visible to anglers, the float tip 12 is coated with three different colored segments: orange, black, and yellow. The black segments are positioned between the orange and yellow segments, and are shorter than both the orange and yellow segments. For easier viewing... Figure 1 Different colors are used to represent the three types of bleaching.
[0046] See Figure 2 and Figure 3 To prevent the connection between the first float shell and the float tip from cracking, the first float body 10 also includes a fixing sleeve 18 made of metal and having a second axial through hole 181. The tail of the first float shell 11 has a first axial through hole 112 that communicates with the first cavity 111. The fixing sleeve 18 is sealed and fixed in the first axial through hole 112 of the first float shell 11, and the float tip 12 is sealed and fixed in the second axial through hole 181 of the fixing sleeve 18. The fixing sleeve 18 is generally made of stainless steel. The first axial through hole 112 has two functions: first, to seal and fix the fixing sleeve 18; and second, to provide a channel for electrical connection between the flexible circuit board 14 and the first circuit board 13.
[0047] See Figure 1The first float shell 11 of the first float body 10 and the second float shell 21 of the second float body 20 are assembled into a hammer-shaped structure that is small at both ends and large in the middle. This makes it easier for the entire fishing electronic float to enter the water and maintain balance.
[0048] See Figure 2 The second cavity 211 of the second float shell 21 also has another function. After the first float shell 11 of the first float body 10 and the second float shell 21 of the second float body 20 are assembled into one piece, the float body formed by the first float body 10 and the second float body 20 together has a hollow space inside. The hollow space is sealed with air, which helps to increase the buoyancy of the entire float body.
[0049] Referring to 2, in order to seal and fix the float foot 22, a first axial hole 212 is provided at the tail of the second float shell 21, and the float foot 22 is fixed in the first axial hole 212 of the second float shell 21. The first axial hole 212 can be made into a blind hole or a through hole. If it is a blind hole, the float foot 22 can be fixed directly. If it is a through hole, the float foot 22 needs to be sealed and fixed.
[0050] See Figure 2 For better sealing, the first float body 10 also includes at least one sealing ring 17; the first cylindrical portion 115 of the first float shell 11 is provided with a groove 1159 that mates with the inner ring of the sealing ring 17; the sealing ring 17 is fitted onto the groove 1159 of the first cylindrical portion 115 of the first float shell 11, and after the external thread 1151 of the first cylindrical portion 115 of the first float shell 11 mates with the internal thread 2911 of the internal thread nest 29 on the second float shell 21, the outer surface of the sealing ring 17 on the groove 1159 of the first cylindrical portion 115 of the first float shell 11 mates with the inner wall of the third axial through hole 291 of the internal thread nest 29 on the second float shell 21, so that the first float shell 11 and the second float shell 21 are sealed together.

It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present utility model, and these all fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
