Description

Technical Field

[0001] The present invention relates to the field of children's toys, in particular to a negative pressure water absorption type fishing toy and a fishing method. Background Art

[0002] In daily life, playing in the water and catching fish is an outdoor recreational activity that children like very much. In order to meet the fishing needs of children, there are mainly the following fishing methods commonly used by children in the prior art: scooping fish, fishing and trap fishing.

[0003] Fishing: Fishing is done using a handheld net. This typically consists of a round or square ring with a net bag and a long handle. The user grips the handle and controls the net bag's movement in the water. Once the target fish is caught, the net bag is quickly pulled out of the water to capture it. This method offers advantages such as ease of use, low cost, no harm to the fish, and the ability to operate in a variety of waters. The process is also highly entertaining. However, its disadvantage is a low success rate.

[0004] Fishing: Fishing is the practice of using fishing gear. Fishing gear typically consists of a rod, line, float, hook, and bait. The baited hook is cast into the water, and after a fish bites, it is dragged ashore to capture it. This method has the advantage of being widely applicable, catching a wide variety of fish, from deep to shallow water, from still to flowing water, and from large to small. However, it also has many disadvantages, making it less suitable for young children. Furthermore, children's active nature often leads to a lack of patience, resulting in a low success rate. Fishing requires a high level of skill and is difficult for children. The sharp tips of hooks are dangerous and can harm the fish caught. Furthermore, the use of bait can pollute the environment.

[0005] Trap fishing: Fish are lured into a trap and then pulled out of the water to catch fish. Trap fishing involves placing bait in the trap, throwing it into the water, and then waiting for a while for a fish to enter before pulling it out of the water. This method has the advantages of being simple and inexpensive. However, its disadvantages are the waiting involved, the lack of entertainment, and the environmental pollution caused by the bait.

[0006] After checking Chinese patent documents, no literature on fishing toys has been found. Summary of the Invention

[0057] The present invention has the advantages of being easy to use and highly entertaining due to the adoption of the above structure.

[0058] Preferably, the present invention further includes a fish positioning structure 5 , which is disposed on the toy body 1 . The positioning point of the fish positioning structure 5 is located within or near the inner plane of the outer end surface of the one-way fish suction nozzle 214 when the fish suction tube 21 is fully extended, and coincides with the approximate center of the internal space of the fish suction nozzle. The fish positioning structure 5 can be a mechanical structure or a photoelectric structure.

[0059] The photoelectric structure can be that the fish positioning structure 5 includes a first light source 51 and a second light source 52, and the first light source 51 and the second light source 52 are arranged on the front end of the toy body 1 at a second predetermined distance. The intersection point of the axis of the light emitted by the first light source 51 and the light emitted by the second light source 52 basically coincides with the center point of the outer end surface of the one-way fish suction mouth 214, generally near the inner side of the center point of the outer end surface, and basically coincides with the approximate center position of the internal space of the fish suction mouth. Specifically, a first right cylindrical groove 138 is provided on the upper side of the front end of the right shell 13, and a second right cylindrical groove 139 is provided on the lower side of the front end of the right shell 13. A first left cylindrical groove 128 and a second left cylindrical groove 129 are also provided at the corresponding position of the left shell 1. The extension line of the upper central axis of the upper cylindrical groove after the first right cylindrical groove 138 and the first left cylindrical groove 128 are closed, and the extension line of the lower central axis of the lower cylindrical groove after the second right cylindrical groove 139 and the second left cylindrical groove 129 are closed intersect at point A, and point A basically coincides with the center point of the fish suction mouth (see Figure 8 ), generally located near the inner side of the center of the fish suction nozzle, substantially coinciding with the approximate center of the interior space of the fish suction nozzle; the first light source 51 is coaxially fixedly mounted within the upper cylindrical groove, and the second light source 52 is coaxially mounted within the lower cylindrical groove. Therefore, the intersection point A of the axes of light emitted by the first light source 51 and the second light source 52 substantially coincides with the center point of the outer end surface of the one-way fish suction nozzle 214. In this embodiment, the first light source 51 and the second light source 52 can be infrared light-emitting tubes or laser light-emitting tubes.

[0060] The first light source 51 and the second light source 52 are powered by a battery (not shown). A power switch is provided between the battery and the first light source 51 and the second light source 52. In this embodiment, the power switch includes a switch contact 53 provided on the top cover 212 of the fish suction tube, and a first switch spring 54 and a second switch spring 55 installed at the rear end of the right shell 13. The first light source 51 and the second light source 52 are connected in parallel to form a parallel circuit with the battery through a wire. The first switch spring 54 and the second switch spring 55 are located in the parallel circuit. The first and second switch springs 54, 55 are configured with a centrally bent protrusion, with the protrusions facing each other and a gap between them. When the fish-suction tube cover 212 is moved back into position, the switch contact 53 is inserted between the first and second switch springs 54, 55, connecting the first and second switch springs 54, 55, thereby forming a circuit between the battery and the first and second switch springs 54, 55, and illuminating the first and second light sources 51, 52. In this embodiment, the first and second switch springs 54, 55 can be made of thin sheets of stainless steel, but are not limited to this material. Any metal sheet with a certain degree of elasticity, such as thin copper or steel sheets, can be used. Of course, the switch structure formed by the first and second switch springs 54, 55, and switch contact 53 can also be replaced by other structures that can achieve a switch function, such as a push button switch or a rocker switch.

[0061] See Figure 5 The one-way fish suction nozzle 214 is preferably made of silicone, but is not limited to this material; other materials are also acceptable. A mounting surface 2141 is provided on the one-way fish suction nozzle 214, and the nozzle is mounted to the free end of the fish suction tube 21 via the mounting surface 2141. For ease of assembly and disassembly, the one-way fish suction nozzle 214 and the fish suction tube 21 can be connected using a quick-release and quick-install structure, such as a threaded connection. In this embodiment, a plurality of oblique strips forming tapered barbs 2142 are provided within the one-way fish suction nozzle 214. The tapered barbs allow the target fish to smoothly enter the fish suction tube 21 through the tapered barbs, but prevent the target fish from exiting the tube 21. When the fish needs to be retrieved, the one-way fish suction nozzle 214 can be removed to eject the target fish. Of course, the tapered barbs 2142 of the present invention can also be replaced with other structures, as long as they allow the target fish to enter without migrating back out.

Figure 10 and Figure 11 The embodiment shown and Figure 1 The illustrated embodiments have generally the same structure, except that the structure of the elastic energy storage device 3 is different. In this embodiment, the elastic energy storage device 3 includes a first tension spring 33 and a second tension spring 34, which are symmetrically arranged, and one end of the first tension spring 33 and the second tension spring 34 is connected to the toy body 1, and the other end of the first tension spring 33 and the second tension spring 34 is connected to the top cover 212 of the fish suction tube. When the fish suction tube 21 is completely moved backward, the first tension spring 33 and the second tension spring 34 are stretched to store energy.

[0064] See Figures 12 to 14 , Figures 12 to 14 Disclosed is a fourth embodiment of the present invention, Figures 12 to 14 The embodiment shown and Figure 1 The illustrated embodiments are generally structurally the same, except that the structures of the elastic energy storage device 3 and the control structure 15 are different. In this embodiment, the elastic energy storage device 3 is a compression spring 35, which is disposed at the rear of the toy body 1. One end of the compression spring 35 is sleeved on the connecting rod 222 and rests on the top cover 212 of the fish suction tube. One end of the compression spring 35 rests on the rear end of the toy body 1. When the fish suction tube 21 is completely moved rearward, the compression spring 35 is compressed and stores energy.

[0065] In this embodiment, the control structure 15 includes a flexible pull cord 151. One end of the flexible pull cord 151 is connected to the connecting pull post 2221, and the other end of the flexible pull cord 151 is connected to the hanging post 152 at the rear end of the toy body 1. The function of the flexible pull cord 151 is to stop the connecting rod 222 from moving forward a predetermined distance when it is pulled by the flexible pull cord 151. In this embodiment, the flexible pull cord 151 is preferably an elastic belt.

[0066] See Figure 14 The present invention also provides a fishing method using the negative pressure water absorption fishing toy, comprising the following steps:

[0067] S1. Forcefully move the negative pressure generator 2 backward along the axial direction of the guide structure 11 of the toy body 1;

[0068] S2. After moving a third predetermined distance, the piston connecting rod structure 22 of the negative pressure generator 2 is blocked by the first predetermined position of the toy body 1 and stops moving backward; the fish suction cylinder 21 of the negative pressure generator 2 continues to move backward until it is locked by the trigger 4; at this time, the elastic energy storage device 3 stores energy, and the piston 221 moves to the vicinity of the one-way fish suction nozzle 214;

[0069] S3, placing the one-way fish suction mouth 214 of the fishing toy into the water, and adjusting the position of the fishing toy so that the positioning point of the fish positioning structure 5 is near the target fish;

[0070] S4, always keep the positioning point of the fish positioning structure 5 on the target fish, pull the trigger 4, and the negative pressure generator 2 is ejected forward as a whole along the axial direction of the guide structure 11 under the action of the release force of the elastic energy storage device 3;

[0071] S5: After the negative pressure generator 2 is ejected forward by the third predetermined distance, the piston connecting rod structure 22 of the negative pressure generator 2 is blocked by the second predetermined position of the toy body 1 and stops moving forward; the fish suction cylinder 21 of the negative pressure generator 2 continues to move forward, and the one-way fish suction nozzle 214 continues to approach the target fish;

[0072] S6. As the fish suction cylinder 21 of the negative pressure generator 2 continues to eject, the movement of the piston 221 of the piston-connecting rod structure 22 relative to the fish suction cylinder 21 generates negative pressure in the fish suction cylinder 21. The negative pressure draws the target fish and the surrounding water into the fish suction cylinder 21.

[0073] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
