Multi-diameter drainage cover

The present invention relates to a multi-caliber drainage cover, and more particularly to a multi-caliber drainage cover for different bottle mouths.

In daily life, in order to effectively carry out cleaning operations such as car washing or glass washing, the sprinkler pipe is usually installed in a container in which cleaning liquid is stored, and then the cleaning liquid is pumped out by means of a motor or a pump or the like. Or glass for scouring. Wherein, the pipeline of the sprinkler is mainly fixed to the container through the cap of the container, and since the conventional cleaning liquid is prepared by the user, it is easy to prepare a large amount of cleaning liquid, and the container is The capacity is also relatively large, which is very inconvenient for the user to carry or move.

As stated above, in order to solve the problem that the cleaning liquid prepared by the user is easily produced due to excessive production, it is necessary to use a larger container to be filled and not to be carried or moved. Therefore, the manufacturer has introduced a prepared vial of cleaning liquid for the user to carry.

However, due to the limited storage of the cleaning solution of the vial cleaning solution, the user may use the large container and the small container according to different needs. At this time, the user must prepare two sets of sprinklers, or prepare two groups. The caps are used interchangeably, and even if two sets of caps are prepared, the sprinkler pipelines have to be reinstalled, which is very time consuming and complicated. petty.

Therefore, the creators of this case believe that it is necessary to develop a new multi-caliber drainage cover that can be installed according to containers of different capacity.

In view of the above, in the prior art, since the user may interact between the large container and the small container, the user often needs to prepare two sets of sprinklers or two sets of caps, which is very inconvenient and takes time. .
