Description

Technical Field

[0001] The present invention relates to fishing tackle, and more particularly to a wireless fishing monitor for monitoring the situation of fish and fishing underwater while floating on the water surface and fishing.

Background Art

[0002] Fishing is a method of using a fishing line to attract fish to a fishing hook with a fishing bait and catch the fish. The most common fishing method is rod fishing, where a fishing rod is extended above the water surface and the fishing line is lowered and manipulated, which has become a popular outdoor recreational sport.

Summary of the Invention

[0003] [Problems to be Solved by the Invention] When fishing, from the movement of the float on the fishing line jumping on the water surface or being pulled underwater, one can know the situation where the fish has bitten the fishing bait or hooked on the fishing hook. When the float is jumping violently on the water surface, it indicates that the fish underwater has bitten the fishing bait. When there is no reaction from the float for a long time, the angler judges that the fish has not bitten the fishing bait, the fishing bait has come off, or there are no fish at the depth where the fishing bait is located. These problems can be understood by experienced anglers, but not by ordinary fishermen.

[0004] Therefore, there are also anglers who purchase a monitor, connect one end of the monitor to a mobile device, and put the monitor into the water to monitor the dynamics of the fish. Such a monitoring method is difficult for the angler to visually recognize the situation where the fish has bitten the fishing bait because the lens put into the water is far away from the fishing bait, and in addition, the water is turbid and the visibility is poor.

[0005] Therefore, the problem that the present invention aims to solve is to be able to know the situation where the fish has bitten the fishing bait or the fishing bait has come off when fishing.

[0006] The present invention has been made by the intensive research of the inventor in view of the above problems, and its object is to provide a wireless fishing monitor. That is, the wireless fishing monitor is tied to a fishing line, and after the fishing line is thrown into the water, the wireless fishing monitor immediately floats on the water surface, takes a video of a fish biting the fishing bait below the wireless fishing monitor, and notifies the fisherman that the fish has bitten the fishing bait.

[0030] As shown in the figure, the wireless fishing monitor 10 according to the present invention includes a monitor module 1, a control circuit 2, a power supply unit 3, a middle cylinder 4, a front cover 5, a support frame 6, and an antenna cover 7. A ring portion 42 for passing the main line 20 and the sub-line (leader or power line) 30 is installed in the middle cylinder 4, and one figure-eight ring 40 is connected between the main line 20 and the sub-line 30. The figure-eight ring 40 prevents the main line 20 from detaching from the wireless fishing monitor 10. After hanging fishing bait (not shown) on the sub-line 30 and throwing the fishing bait underwater, the monitor module 1 monitors the underwater fishing situation, and the captured video is transmitted to the receiving device 50 at the receiving end (see FIG. 8), enabling the user to view the situation where the fish underwater bites the fishing bait.

[0031] The monitor module 1 includes an image reading lens 11, a supplementary light circuit board 12, and an adapter circuit board 13.

The closed end 52 has a transparent window 54, and the transparent window 54 is used for the image reading lens 11 to capture the video of the fish biting the fishing bait. Also, when fishing at night, the light source generated by these LEDs 121 of the auxiliary lighting circuit board 12 is irradiated from the transparent window 54, making it easier for the fisherman to see the situation of the fish underwater biting the fishing bait.

[0036] The support frame 6 includes a fixing plate 61 having a plurality of through holes 611. By passing screws 60 through these through holes 611, the fixing plate 61 is locked to the screw holes 231 of the support plate 23 and the lock holes 441 of the rib 44 to fix the control circuit 2. Also, the fixing plate 61 has a catheter 62, and the catheter 62 allows the antenna 24 electrically connected to the second circuit board 22 to pass through, preventing the situation where the antenna 24 is damaged when an external force is applied during the installation of the antenna 24.

The clamping tool 43 is pushed to open the mouth portions 432 of the two clamping tools, and the fishing line 20 is pulled to adjust the depth at which it is put under the water surface. After adjustment, the two elastic members 431 are loosened, and the fishing line 20 is clamped by the mouth portions 432 of the two clamping tools.

[0040] After hanging fishing bait on the fishing hook on the sub-line 30 and throwing it in, the wireless fishing monitor 10 floats on the water surface like a float. At this time, the monitor module 1 monitors the fishing situation under the water surface and transmits the captured video to the receiving device 50 at the receiving end (see FIG. 8), so that the user can see the situation where the fish under the water surface bites the fishing bait.

[0041] When a fish is hooked, or when the fishing hook is cut by a stone or a heavy object, the eight-shaped ring 40 prevents the fishing line 20 from detaching from the wireless fishing monitor 10, and the wireless fishing monitor 10 is pulled back by the fishing line 20, and the sub-line 30 and the fishing hook (not shown) are tied to the eight-shaped ring 40 again.
