Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a faucet attachment that is attached to the end of a water pipe in a home kitchen, washroom, or the like.

<Prior Art> Conventionally, a faucet attachment that also serves as a strainer has been used to prevent water discharged from the faucet from splashing around. Up until now, this type of faucet attachment was considered to be sufficient as long as it simply performed its function, but recently people have started to appreciate things that can add a sense of warmth and enjoyment by attaching it. It's here. On the other hand, the market is flooded with a variety of character products, driving people's desire to purchase them.

<Problem to be solved by the invention> This invention is easy to produce when commercializing a character for a faucet attachment, is simple to use, and requires no effort, and if you get tired of the character, you can use a different character. The purpose of this invention is to provide a faucet attachment that can be replaced with other faucet attachments.

<Means for Solving the Problems> The faucet attachment of the present invention includes an inner cylinder made of soft synthetic resin having an inverted conical tongue piece formed at the inner edge of the upper end for tightly fitting the end of a water pipe, and the inner cylinder. a hemispherical filter having a flange that can be fitted into an engagement groove formed at the inner edge of the lower end; and an outer cylinder that is shaped into various character shapes and that can be fitted onto the outside of the inner cylinder. It consists of a combination of, and the inner cylinder and outer cylinder have
An engagement structure that fits into each other and acts as a stopper in the rotational direction and an engagement structure that acts as a stopper in the vertical direction are formed, and the free end of the lower edge of the outer cylinder is located below the flange. The end face can be supported.

<Function> The engagement structure that acts as a stopper in the vertical direction allows the inner cylinder and outer cylinder to be separated separately when this faucet attachment is tightly fitted into or removed from the end of a water pipe. In addition, during use, the filter cooperates with the free end of the lower edge of the outer cylinder to ensure that the filter does not fall out even if water pressure is applied to the filter.
The engagement structure, which acts as a stopper in the direction of rotation, ensures that once the outer cylinder is correctly installed facing the front, the direction will not change even if some external force is applied, and the character's face will always face forward. do.

<Example> An example of the faucet attachment of this invention will be explained using Figs. 1 to 4. This includes an inner cylinder 1 made of soft synthetic resin, a hemispherical filter 4, and various characters. The inner cylinder 1 consists of an outer cylinder 6 formed into a mold, and the inner cylinder 1 has an inverted conical tongue piece 2 formed on the inner edge of the upper end for tight fitting to the end of the water pipe, and an inverted conical tongue piece 2 on the inner edge of the lower end. A matching groove 3 is formed, and
On the outer surface, in cooperation with the outer cylinder 6 described below,
They form a protrusion 7a that fits into each other and serves as a stopper in the rotational direction, and an annular strip 8a that serves as a stopper in the vertical direction. . The hemispherical filter 4 has a flange 5 that can be fitted into the engagement groove 3 of the inner cylinder 1. Inside the outer cylinder 6, there are a fitting part 7b, which is the other part of the engagement structure that acts as a stopper in the rotational direction, and an annular fitting part 8b, which is the other part of the engagement structure, which acts as a stopper in the vertical direction. is formed. 9 is the outer cylinder 6
This is the free end of the lower edge of.

To assemble, first put the filter 4 inside the outer cylinder 6, receive the flange 5 of the filter 4 at the lower free end 9 of the outer cylinder 6, and then insert the inner cylinder 1 inside the outer cylinder 6. , the protruding portion 7a and the fitting portion 7b, and the annular strip portion 8a and the annular fitting portion 8b are engaged and locked, respectively. As a result, the flange 5 of the filter 4 is connected to the inner cylinder 1.
It will fit into the engagement groove 3 of.

To use the faucet attachment assembled in this way by attaching it to the end of a water pipe, hold the outer cylinder 6 and firmly fit the tongue piece 2 of the inner cylinder 1 into the end of the water pipe, and then Attach the character 6 so that its face faces forward.

<Effects of the invention> As is clear from the above explanation, the faucet attachment according to the invention has an assembly structure in which the inner cylinder, outer cylinder, and filter are fitted together, so it is difficult to apply some force to the inner cylinder made of soft synthetic resin. In addition, after removing it from the outer cylinder, it is possible to fit an outer cylinder of a different character, that is, to reuse the inner cylinder 1 and replace the outer cylinder 6 with one of a desired character. In addition, since we have provided an engagement structure that acts as a stopper in the vertical direction, it is difficult to separate the inner cylinder and outer cylinder from each other, making it easy to attach and remove them from the end of the water pipe, and when in use, the outer cylinder It works together with the free end of the lower edge of the filter to prevent it from falling out even when water pressure is applied to the filter. Furthermore, since we have provided an engagement structure that acts as a stopper in the direction of rotation, once the outer cylinder is correctly attached facing the front, there is no need to change the direction of the character's face.
