本発明は、フッ素樹脂製および／またはオレフィン系樹
脂製のフィルターに関する。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a filter made of fluororesin and/or olefin resin.

るハウジング上部（３）とで形成されている。Prior art filters typically include a filter element (1) consisting of a filter cloth or membrane for removing contaminants in a liquid or gas, a housing lower part (2) in which the filter element is mounted;
The lower part of the housing is attached to the upper part of the housing (3), which together serve as a housing.
解決すべき問題点
通常、ハウジング上部はハウジング下部の溝（４）に挿
入された後融着し固着されている。Problems to be Solved Usually, the upper part of the housing is inserted into the groove (4) in the lower part of the housing and then fused and fixed.

があり、かつ摩擦抵抗が小さいので、融着が不十分であ
ると融着部より気液が噴出し、最悪のばあいはハウジン
グ上部とハウジング下部とが完全に外れることとなる。The filter element (1) is inserted into the protrusion (5) at the bottom of the housing and then fused and fixed. Gaseous liquid to be filtered enters through the opening (6) at the top of the housing and exits from the filter element (1). It is fine if the gaseous liquid that is filtered and exits through the opening (7) at the bottom of the housing can pass through the element without much resistance, but if the filtration resistance is large or high pressure filtration is used, the housing will be pushed outward. Since a force is applied in the direction, a force is applied so that the connection between the upper part of the housing and the lower part of the housing comes off.If this is the case, if the filter is made of fluororesin and/or olefin resin, it will have some degree of shape deformation. In addition, since the frictional resistance is small, if the welding is insufficient, gas and liquid will gush out from the welded portion, and in the worst case, the upper housing part and the lower housing part will come off completely.
ハウジング上部とハウジング下部とをネジ込みにより固
定する方法もあるがネジ切りのための特別な治具が必要
となり製造工程が繁雑となる。Although there is a method of fixing the upper part of the housing and the lower part of the housing by screwing, this requires a special jig for cutting the screws, which complicates the manufacturing process.

The resin to be used may be determined depending on the properties of the gaseous liquid to be filtered, and a combination with a different olefin resin, a combination with a different fluororesin, or a combination of an olefin resin and a fluororesin may be used.
以下、図面に従い詳しく説明する。A detailed explanation will be given below according to the drawings.

The figure shows details of the connection between the upper part of the housing and the lower part of the housing, and FIG. 3 shows the details of the connection part of the lower part of the housing with the upper part of the housing.
ハウジング下部（２）はほぼ円盤状で中央に排出口（７

), on the outside there is a protrusion (5) for connecting the fill element, and on the outside there is a groove (4) that connects the upper part of the housing.

。The groove (4) in the lower part of the housing extends around the entire circumference of the lower part of the housing and is provided with several recesses (8) on the outside. The depression (8) is not rounded. The depression may be provided on the inside.

なり、その後傾斜部分（１０）を設は若干の平行部（１
４）の後、はぼ直角に内方に段落（１５）している。The upper part of the housing (3) is approximately bell-shaped, and has an inlet (6) and an air bend (13) at its sealed end (12), and a head (4) to be inserted into the groove (4) in the lower part of the housing at the other end. 9
). The head (9) has a protrusion (11) protruding from the outside of the ring. In other words, the tips of several heads have rounded corners, followed by an inclined part (10) and some parallel parts (10).
After 4), there is a step (15) inward at right angles.

ウジング上部の頭部（９）を挿入すると、先端が丸みを
持っているので容易に挿入し、ハウジング上部端傾斜部
分（１０）で溝の先端を押し広げ突起（１１）が溝に嵌
まり込み該突起が溝の縁にで止まり離れることはない。The groove at the bottom of the housing and the edge at the top of the housing are as shown above, so when you insert the head (9) at the top of the housing into the groove (4) at the bottom of the housing, it will be easy to insert because the tip is rounded. However, the tip of the groove is pushed out by the inclined portion (10) at the upper end of the housing, and the protrusion (11) is fitted into the groove, so that the protrusion stops at the edge of the groove and does not separate.

記突起と溝とが嵌合しているので引離す力が融着部分に
かかることなく該融着部が離れることはない。If the lower part of the housing and the upper part of the housing are melted and bonded together in such a state, the seal will be perfect, and even if a force is applied in the direction of separating the lower part of the housing and the upper part of the housing, the protrusion and groove will fit together. Therefore, the fused portion does not separate without any force acting on the fused portion.

本実施例ではチューブラ一方式で説明する。In this embodiment, a tubular type will be explained.
チューブラ一方式のフィルターエレメントは円筒状本体
コアの外周に濾過月を設置する。A tubular one-type filter element has a filtration ring installed around the outer periphery of a cylindrical main body core.

。円筒状膜を本体コアに挿入してその解放上下端を本体
コアに熱接着する。The membrane and the net are overlapped, and both ends are melt-bonded with the molten film sandwiched between them to form a cylindrical shape, with the net facing the main body core side. A cylindrical membrane is inserted into the main body core and its free upper and lower ends are thermally bonded to the main body core.
このフィルターエレメントをハウジング下部のエレメン

If the above-mentioned method of connecting the upper part of the housing and the lower part of the housing is used, even if gas and liquid enter from the lower part of the housing and a force is applied in the direction of separating the filter element from the lower part of the housing, the filter element will not move. Never leave the bottom of the housing.

てもその製造工程は繁雑とならない。Effects The filter according to the present invention connects the upper and lower parts of the housing by fitting using the recesses and protrusions, and then fuses them together, so even if a force is applied in the direction of separating the upper and lower parts of the housing, the fitting will not prevent the above-mentioned fitting. In response to this force, the upper and lower parts of the housing will separate and no gaseous liquid will be ejected. The manufacturing process is less complicated than that in which the upper and lower parts of the housing are joined using screws.
