【Example】

An embodiment of the present invention will be described below with reference to the drawings.

[0008] In Figures 1 to 3 showing the configuration, 1 is the main body of a Western-style toilet, with a water tank on the back. A hot water tank 2 and a hot water tank 3 are attached, and between these two tanks 2 and 3, respective two tanks 2 and 3 are installed. A water supply hose 4 is provided that communicates with the water supply hose 3. 8 is a cylinder, and there is a nozzle inside which will be described later. The nozzle cap has an approximately oval-shaped opening 8b at its tip. It is equipped with a water inlet 8c and a water inlet 8d at multiple locations on the side. The vicinity of the tip is fixed above the section.

[0009] 7 is a hollow sealed nozzle body made of, for example, a metal pipe, with a nozzle at the tip. The screw cap 7d is press-fitted, and the front end has a spout 7a and the rear opening has a piston 7b. Moreover, there is a nozzle body 7 between the piston 7b and the inner tip of the cylinder 8. A spring 9 is interposed therebetween to bias it in the direction of retracting. Also, this nozzle body 7 is The shape is oval, and an appropriate number of rotation regulating guides 7e are provided, and the tip of the cylinder 8 is A digging part 11 having a minute clearance is provided between the rotation regulating guide 7e and the rotation regulating guide 7e. There is.

0010 By doing this, the nozzle body 7 moves back and forth into the cylinder 8 via the spring 9. freely held. 7c is the water inlet, which passes through the piston 7b and enters the nozzle body 7. This water inlet 7c is connected to the empty space, and this water inlet 7c supplies hot water from the hot water tank 3 to the inside during cleaning. This is the part that sends it into the empty space. 6 is a branch pipe and a water supply member (for example, an electromagnetic pump) 5 It is installed between the hot water tank 3 and the cylinder 8 via the branch water supply port 6a and the branch water supply port 6a. The water supply port 6b is connected to the water supply port 8c and the water supply port 8d, respectively. 10 is the lid, cylinder 8 It is attached so that the rear end is sealed.

[0011] Next, the operation of the above configuration will be explained.

0012 When you operate the operation part (not shown) to wash any private part after using the toilet, the water supply part The hot water is passed through the branch pipe 6 by the material 5 to the branch water inlet 6a and the branch water inlet 6b, respectively. Water is supplied to the hollow part of the cylinder 8 from the water supply port 8c and the water supply port 8d connected to the water supply port 8c and the water supply port 8d. this The hot water from the water supply port 8c becomes pressure water and flows into the cylinder 8 between the piston 7b and the lid 10. Water is pumped inside.

[0013] On the other hand, the pressure water from the water supply port 8d flows into the space between the piston 7b and the tip inside the cylinder 8. Water is sent to the hollow part, but there is a small clearance between the tips of cylinder 8 and digging. Water leaks from the gap in the section 11 and the nozzle body 7 is cleaned. Therefore, the pressure from water supply port 8c The power water flows from the minute clearance between the tips of the cylinders 8 and the gap in the digging part 11. Helped by the water leakage, the piston 7b is pushed and the spring 9 is compressed, causing the nozzle to open as shown in Figure 3. The main body 7 is projected forward from the opening 8b.

[0014] Moreover, when the nozzle body 7 has finished protruding completely, the nozzle passes through the piston 7b. The water inlet 7c that communicates with the hollow part of the drain body 7 coincides with the water supply port 8d, and the hot water tap The hot water from the tank 3 passes through the hollow part of the nozzle body 7 and is directed to any local area from the spout 7a. and squirt water out. Also, since the water inlet 7c is in close contact with the inside of the cylinder 8, During the ejection operation of the nozzle body 7, almost no pressure water enters from the water inlets 8c and 8d. It does not enter the hollow part of the nozzle body 7 through the water port 7c.

[0015] When water is gushing out, the rotation regulating guide 7e is aligned with the digging part 11, so the nozzle main Due to the gap between the body 7 and the opening 8b, the axial rotation of the spout 7a of the nozzle body 7 becomes slightly It is sprayed towards the area without wavering from side to side.

[0016] In addition, in Fig. 4, there is one rotation regulating guide 7e and one digging part 11, but the same effect can be achieved even if there are two or more. has the effect of

[0017]

[Effect of the idea]

As described above, according to the present invention, an appropriate number of rotation regulating guides are provided in the nozzle body, and Furthermore, a recessed part with a minute clearance between the opening and the rotation regulation guide is provided. , align the rotation regulation guide with the digging part to prevent shaft rotation due to the gap between the nozzle body and the opening. Since the amount of water is minimized, a guiding effect of the jet water can be obtained, improving straightness and ejecting water. The water is sprayed towards the private parts without shaking from side to side, preventing the user from feeling discomfort. It has the advantage of being able to supply nozzles for sanitary cleaners.
