【発明の詳細な説明】 産業上の利用分野 本発明は、局部の洗浄に使用する衛生洗浄装置の洗浄ノ
ズルに関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning nozzle of a sanitary cleaning device used for cleaning local areas.

に、第４図の様な構成になっていた。2. Description of the Related Art Generally, a cleaning nozzle of a sanitary cleaning device is disclosed, for example, in Japanese Patent Application No. 59-1.
As shown in Japanese Patent No. 71915 (Japanese Patent Laid-Open No. 61-49043), the structure is as shown in FIG.

る。また10は給水部である。That is, the nozzle 2 is slidably mounted in the cylinder 1,
The nozzle 2 is always biased by a spring 3 in a direction to be housed in the cylinder 1, and is normally completely housed in the cylinder 1. The nozzle 2 is provided with a flow receiving port 4 and a pressure receiving / sealing portion 5 which is perpendicular to the center line of the nozzle 2, a water passage 6 and an ejection port 7, and a packing 8. Reference numeral 9 denotes a guide portion, which restricts the rotation of the nozzle 2 by making the fitting cross-section with the nozzle 2 a hexagon as shown in FIG. 10 is a water supply section.
11はシリンダ１とガイド部９の水シール用パッキング
で、12はシリンダ１と給水部10の水シール用パッキング
である。Reference numeral 11 is a water seal packing for the cylinder 1 and the guide portion 9, and 12 is a water seal packing for the cylinder 1 and the water supply portion 10.

な噴出となる。When water is supplied from the water supply unit 10 into the cylinder 1, the pressure receiving / sealing unit 5 is pushed by the water pressure, so that the nozzle 2 resists the force of the spring 3 to move the pressure receiving / sealing unit 5 of the nozzle 2 into the cylinder 1. The cylinder 1 slides in the direction of the guide 9 side as a slide guide for the inner surface. At this time, the water that has entered from the water flow port 4 and passed through the water passage 6 is ejected from the ejection port 7,
While the nozzle 2 is sliding, some leakage occurs from the gap between the nozzle 2 and the guide portion 9, resulting in incomplete ejection. After that, when the nozzle 2 is completely projected, the gap between the nozzle 2 and the guide portion 9 is sealed by the packing 8, so that all the supplied water is ejected from the ejection port 7 to be a complete ejection used for cleaning the local area. .

局部の洗浄が出来ないという問題点があった。However, in the case of such a structure, when the pressure of the supplied water is low, when the nozzle 2 is completely projected, the reaction force of the ejection from the ejection port 7 causes the nozzle 2 to move. Is inclined with respect to the center line of the cylinder 1 by the dimension of the clearance between the pressure receiving / sealing section 5 and the cylinder 1 with a contact point with the guide section 9 as a fulcrum, and a partial clearance is provided between the packing 8 and the guide section 9. Because it occurs
There is a problem that the seal between the nozzle 2 and the guide portion 9 by the packing 8 is incomplete, water leaks out, and incomplete jetting occurs, so that sufficient local cleaning cannot be performed.
そこで本発明は、供給された水の圧力が低い場合でもノ
ズルの摺動をスムーズにするとともに、ノズルとガイド
部のシール性を向上し、供給された水が全て噴出口より
噴出して、充分に局部の洗浄を可能にするものである。Therefore, the present invention smoothes the sliding of the nozzle even when the pressure of the supplied water is low, improves the sealing property between the nozzle and the guide portion, and the supplied water is all jetted from the jet outlet, It enables local cleaning.

を有する構成とすることである。Means for Solving the Problems Technical means of the present invention for solving the above problems comprises a cylinder having a water supply part and a guide part, and a nozzle that slides in the cylinder, and the nozzle has an ejection port at one end. And a pressure receiving / sealing portion having a shape similar to the internal cross section of the cylinder, which is slightly smaller than the internal cross section of the cylinder, in a positional relationship orthogonal to the center of the nozzle axis on the other end side of the jet outlet, The pressure receiving / sealing portion has a pressure receiving portion at the other end extending from the pressure receiving / sealing portion on the side opposite to the ejection port and having a positional relationship parallel to the pressure receiving / sealing portion.
作用 この技術的手段による作用は次の様になる。Action The action of this technical means is as follows.
即ち、ノズルに噴出口からの噴出による抗力が働いて
も、ノズルは、供給された水の水圧を、受圧兼シール部

が向上される。したがって供給された水の水圧が低くて
も、その水は全て噴出口より噴出して、充分な局部の洗
浄を可能にすることができる。That is, even if a drag force is exerted on the nozzle from the ejection port, the nozzle receives the water pressure of the supplied water in addition to the pressure receiving / sealing portion, so that the water pressure is received only by the conventional pressure receiving / sealing portion. The force with which the water pushes the nozzle is greater than when it is received, and the sealing performance between the nozzle and the cylinder at the pressure receiving / sealing portion is improved. Therefore, even if the water pressure of the supplied water is low, all of the water can be ejected from the ejection port to enable sufficient local cleaning.

A pressure receiving portion 19 and an ejection port 20 are provided, and the pressure receiving and sealing portion 17 is perpendicular to the center line of the nozzle 14, has a similar shape slightly smaller than the internal cross section of the cylinder 13, and has a packing 21.
The pressure receiving portion 19 is in a position parallel to the pressure receiving / sealing portion 17, and has a shape as shown in FIG. Reference numeral 22 is a guide portion which is integrated with the cylinder 13 and regulates the rotation of the nozzle 14 by making the fitting cross section with the nozzle 14 hexagonal as shown in FIG.

れる。When water is supplied from the water supply unit 23 into the cylinder 13, the pressure-receiving / sealing unit 17 is pushed by water pressure, so that the nozzle 14 resists the force of the spring 15 and moves the pressure-receiving / sealing unit 17 of the nozzle 14 to the inner surface of the cylinder. As a sliding guide, it slides in a direction opposite to the water supply port 23 while maintaining a positional relationship substantially parallel to the center line of the cylinder 13. At the same time, the water that has entered the water flow port 16 and passed through the water passage 18 is ejected from the ejection port 20, but while the nozzle 14 is sliding, it slightly leaks from the gap between the nozzle 14 and the guide portion 22,
It is an incomplete eruption. Then, when the nozzle 14 is completely projected, the packing 21 causes the nozzle 14 and the guide portion 22 to
The space is sealed. At this time, the nozzle 14 is pushed in the direction opposite to the jet direction of the washing water by the reaction force caused by the jetting of the washing water from the jet port 20 of the nozzle 14, but since there is the pressure receiving portion 19, the pressure receiving / sealing portion 17 is provided. In addition, since the water pressure of the water supplied by the pressure receiving portion 19 is received, the force with which the water pushes the nozzle 14 is larger than when the water pressure is received only by the conventional pressure receiving and sealing portion 17, and the water pressure of the supplied water is low. However, due to the packing 21 of the pressure receiving / sealing portion 17, the nozzle 14 and the guide portion 22 are
The sealing property between them is improved, and all the water can be ejected from the ejection port 20 to enable sufficient local cleaning. In the present embodiment, the shape of the pressure receiving portion is described as being completely different from the pressure receiving / sealing portion, but even if the pressure receiving portion has a shape similar to that of the pressure receiving / sealing portion, the same effect can be obtained. To be

して、充分に局部の洗浄を可能にすることができる。EFFECTS OF THE INVENTION As described above, according to the present invention, even if the water pressure of the water supplied to the nozzle is low, the pressure receiving section has the pressure receiving section, so that the pressure receiving section receives the water pressure of the supplied water in addition to the pressure receiving and sealing section. Therefore, compared with the conventional case where water pressure is applied only to the pressure receiving and sealing part, the force of water pushing out the nozzle becomes larger, the nozzle slides more smoothly, and the sealing property between the nozzle and cylinder by packing is improved and All can be ejected from the ejection port to enable sufficient local cleaning.
