Buoyancy ball for cleaning poplar wadding on water surface of open-air fishing fishpond
Technical Field
The invention relates to the technical field of fishing, in particular to a buoyancy ball for cleaning poplar flocs on the water surface of an open-air fishing pond.
Background
Fishing is a leisure entertainment's mode, receives liking of many people, and the facility construction about fishing is more and more perfect at present, has indoor fishing center and outdoor fishing place, and people's door can like the different modes of fishing of selecting according to the difference, but in spring, along with the production of poplar wadding, outdoor fishing receives very big influence, and is outdoor, and people can avoid the poplar wadding through gauze mask and umbrella, but the poplar wadding floats can influence the experience of fishing on the surface of water.
In the outdoor fishing process, if the poplar wadding floats on the water surface, the fishing line can be driven by a group of poplar wadding, the fishing person observes the dynamic state of the unclear fishing line, the fishing line is frequently mistakenly hooked, in addition, the water surface poplar wadding can be gathered together due to the action of water, the blocking of the fishing line can be enclosed on the fishing line, the fishing person can wind the fishing line together carelessly, the water surface poplar wadding brings the extremely bad experience for the fishing, and the applicant is deeply experienced, so the idea of the invention is created through germination.
The applicant searches relevant patents when creating the invention, but does not find closely related patent applications, but finds some water surface cleaning devices in patent websites, such as CN201310122918.9 and CN201320176728.0, both patents contain structures for cleaning water surface, but both patents are in the shape of a small boat with a large body, however, the poplar wadding is blown up with the wind and can continuously fall on the water surface, if a boat or other large cleaning device works on the water surface during fishing, the fishing is extremely influenced, in a fishpond with limited space, a fishing boat can assist in fishing, but a boat which continuously salvages poplar catkins cannot assist in fishing, but a user can fall one fish, and a common cleaning device is inconvenient to clean the water surface poplar catkins unless blind cats touch dead bugs, floating poplar catkins easily influence the fishing experience, so that the buoyancy ball for cleaning the water surface poplar catkins in the fishpond for outdoor fishing is needed.
