Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a filtration device using a transparent container in which a metal pipe is connected to a glass pipe.

PRIOR ART In general, the container of a filter device connected to a water faucet or the like is made of an opaque material such as synthetic resin.

Problems that the invention aims to solve: Therefore, with this conventional filtration device, it is not possible to see how dirty the filter inside is.
Currently, the water coming out of the water outlet is placed in a transparent glass container and viewed through it, and the level of dirt on the filter device is observed by checking the irritation of the tongue.

Means for Solving the Problems In order to solve the above problems, the present invention has two metal rings with screws on the outside and tapered from inside to outside that are loosely attached to a transparent glass pipe. Then, both ends of the glass pipe are heated and the softened parts are embossed with the ring, the metal ring is separated, and after both ends of the glass pipe have cooled, a sealant or adhesive is applied to the inner surface of the metal ring at both ends. A glass pipe fixed by applying an agent, a lid body having threaded parts each screwed into metal rings at both ends of the glass pipe and connected to a source water or a water outlet, and one of the lid bodies. and a filter having a threaded portion that is screwed into the inside of the filter.

Effects According to the present invention, it was possible to fix a metal ring to a transparent glass pipe, and by attaching a filter to a container made of this glass pipe, it was possible to ensure that the dirt inside the filter was kept in check. Therefore, even though it is past the time to replace the filter, there is no need to use it to drink clean water, and it is possible to use a diatomaceous earth filter as a filter. By doing so, you can use cleaner water.

Embodiment FIG. 1 is an explanatory diagram for making a container in which a metal ring is fixed to a glass pipe used in a filtration device according to an embodiment of the present invention. First, as shown in FIG. , two metal rings each having a taper on the inner surface 2a, 3a, the outer diameter of which is large and the inner diameter is approximately the same as the outer diameter of the glass pipe 1, and threaded portions 2b, 3b on the outer surface. Attach 2 and 3 loosely. Then, the ends 1a and 1b of the glass pipe 1 are heated with a heater such as a gas burner, and the ends 1a and 1b of the glass pipe 1 are heated.
When the metal rings 1b become red hot and soft, the metal rings 2 and 3 are moved to the heated ends 1a and 1b of the glass pipe 1, respectively, and the glass is pressed by a stamping part (not shown) having a tapered outer shape. The heated end 1a of the pipe 1 is pushed and expanded from the inside to the outside. Then, when the metal rings 2 and 3 are removed inward from the heated end 1a of the glass pipe 1, the glass pipe 1
Since the end portion 1a of is expanded outward, this end portion 1a is cooled as it is. Next, Figure 1b
As shown in FIG.
Apply adhesive or sealant to 3a,
When the metal rings 2 and 3 are pressed against the cooled end 1a while being twisted, the metal ring 2 is firmly fixed to the end 1a of the glass pipe 1.

The threaded portion 2 of the metal ring 2 of the container made of the glass pipe 1 (see Fig. 2a) constructed in this way
The threaded portion 4a of the lid 4 shown in FIG. Further, the threaded part 6a of the filter 6 is fitted into the threaded part 4b inside the lid body 4, and the third
The filtration device is configured as shown in the figure. Further, the threaded portion 4c of the lid 4 is connected to an external water outlet, and the threaded portion 5b of the lid 5 is connected to a water source.

In the filtration device of this embodiment configured in this way,
When clean water is poured from the screw part 5b side of the lid 5,
It is pressurized in a transparent glass pipe 1 and passed through a filter 6.
The water enters the filter device 6, passes through the threaded portion 4c of the lid 4, and is discharged from the water outlet.

The filter 6 is configured by press-molding a mixed mixture of diatomaceous earth and an appropriate amount of plastic dissolved in a volatile solvent into a cylindrical shape in an as-pulverized state, and converting this cylindrical molded product into a volatile solvent. Frames 6c and 6d made of synthetic resin are adhered to both ends of a molded product 6b that has been dipped in a solvent and then dried and solidified, and a diatomaceous earth filter is used in which the frame 6c is provided with a threaded portion 6a. Alternatively, a filter using general activated carbon or the like may be used.

By configuring the filtration device of this embodiment in this way, the transparent glass pipe 1 is used, so that
As shown in FIG. 3, dirt on the filter 6 can be monitored through the glass pipe 1, and therefore, it is possible to know with certainty when it is time to replace or clean the filter 6. The glass pipe 1 may be transparent, but even if it is not transparent, it can be used satisfactorily, and it is desirable to use tempered glass as the material for the glass pipe.

Effects of the invention As is clear from the above explanation, the present invention allows the filter to be monitored for dirt by attaching the filter to a container made of a transparent glass pipe.
Therefore, there is an advantage that it is possible to know with certainty when it is time to replace the filter.
