Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a human body private parts cleaning device used in a toilet, particularly to an improvement of a cylinder nozzle device.

Generally, this type of device is configured to perform anal cleaning after defecation (hereinafter referred to as "shower cleaning") and female genital cleaning (hereinafter referred to as "bidet cleaning"). In the case of conventional devices, the piston body is reciprocated within the cylinder by sending water pressure to the front or rear surface of the piston body.

However, with this method, it was necessary to provide a pipe to contain the water, and it was also necessary to take measures to prevent water leakage. If water leakage occurs, failures such as inoperability of the piston body may occur.

In view of these conventional drawbacks, the present invention installs a coil that generates magnetic force at the rear end 1 of the fixed cylinder, and generates or extinguishes the magnetic force by turning the switch ON and OFF by the user, thereby cleaning the shower. To provide a cylinder nozzle device for cleaning human body private parts, in which the first piston body is fixed to the rear end of the fixed cylinder only when the first piston body is fixed, so that there is no need to worry about water leakage, and in addition, reliable operation can be expected. be.

Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of the present invention.
In the figure, first let's talk about the water supply route.
Reference numeral 1 denotes a water supply tank, and water from the tank 1 passes through a filter 2, is sucked and discharged by a pump 3, and is sent to a hot water tank 5 via a check valve 4. The hot water tank 5 has a heater 6, a thermostat 7, and a current plate 8.
The configuration is such that hot water heated to an appropriate temperature inside is sent from a discharge port 9 to a system line 10.

Next, the description will move on to the cylinder nozzle device S (the part shown in the cross-sectional view in FIG. 1). code 11
is the ceramic wall of the toilet bowl, and the fixed cylinder 1 is mounted on the wall 11.
The front end of 2 (on the right side in the figure; the same applies hereinafter) is the seat plate member 1
3. It is fixed with a nut 15 and a tightening member 16 via a packing 14. A tightening member 17 having threaded portions on the outer and inner peripheries is screwed and fixed to the rear end (left side in the figure; the same applies hereinafter) of the fixed cylinder 12 via a sealing member 18 . A magnet member 20 having a coil 19 inside is fixed to the outer circumferential threaded portion of the tightening member 17, and a cap member 21 having a through hole 21a is fixed to the rear portion of the magnet member 20. The cap member 21 has an extension portion 21 extending forward in a flap shape.
b is formed.

A first piston body 22 is attached to the rear end of the fixed cylinder 12 so as to be slidable in the axial direction.
A passage 22a through which water flows is formed inside the first piston body 22, and a space between the rear inclined surface 22b and the extension portion 21b is in the illustrated state (the large diameter portion of the first piston body 22 is A slight gap a (magnetic gap) exists in the state in which the tightening member 17 is in contact with the shoulder portion 17a and is in the rearmost position. When abutting against the shoulder portion 17a, a backward biasing force of the first spring 23 acts. Further, a rear end of a movable cylinder 24 is screwed and fixed to the first piston body 22 . The movable cylinder 24 is slidably attached to the inner peripheral surface of the sleeve 25, and a nut 26 is screwed and fixed to the front end. A groove 25a is formed in the sleeve 25 in the axial direction, one end of the first spring 23 is locked at the rear end, and a stopper ring 27 attached to the fixed cylinder 12 is abutted at the front end to prevent forward movement. Movement is restricted. The groove 25a communicates with a drain line 28, and the waste water that has passed through the orifice 29 flows through the line 28 in the direction of the arrow in the groove 25a.

A second piston body 31 that is slidable in the axial direction is installed in the movable cylinder, and the second piston body 31 is slidable in the axial direction.
A nozzle 32 is screwed and fixed to the front end of the holder.
A second spring 33 is provided on the outer periphery of the nozzle 32 so as to bias the second piston body 31 rearward. The front end of the second spring 33 is engaged with the nut 26 via a stopper 34.

The nozzle 32 can extend forward while being guided by the nut 26, and has a plurality of spout ports 32a opened upward at the front end thereof, and the openings are closed by plugs 32b. One small hole 32c for draining water is bored on the opposite side (lower side) of the spout 32a. A poppet valve 35 is disposed at the rear end of the nozzle 32 so as to be biased rearward by a small spring 36. In the state shown in FIG. 1, the poppet valve 35 is in contact with the second piston body and closed, and this sealing action creates a gap between the rear space A inside the first piston body 22 and the front space B inside the nozzle 32. Separated, water does not flow from space A to B. It flows only when the water pressure increases and the small spring 36 is deflected.

The coil 19 is connected to a switch 38 via a cable 37, and when the switch 38 is turned ON, a current flows through the coil 19, generating magnetic force, and the first piston body 22 is attracted toward the extension portion 21b. It will be done. Therefore, the first piston body 22 does not move forward even if it receives water pressure from the through hole 21a.
It is stopped in the state shown in the first diagram. On the other hand, when the switch 38 is OFF, the magnetic force is not generated,
The first piston body 22 is in a state where it can move forward.

Next, we will discuss the effect.

First, when cleaning the shower, the user turns on the switch 38 and operates a control lever or switch (not shown), which opens the check valve 4 and heats the water from the tank 1 to an appropriate temperature in the hot water tank 5. It is sent from the system 10 to the through hole 21a. coil 1
9 maintains the first piston body 22 in the rearmost position shown in the first diagram, the through hole 21a
The water pressure from the second piston body 31 acts on the rear end surface of the second piston body 31 to move the piston body 31 and the nozzle 32 forward (in this case, the poppet valve 35 does not open at all). This continues until the stopper 32d comes into contact with the stopper 34, and the poppet valve 35 opens almost simultaneously with this contact. As a result, cleaning water flows from space A to space B, and water is ejected upward from the spout 32a at the tip of the nozzle 32.
The user can perform the desired shower cleaning.

Here, the position of the shoulder portion 32d is set to match an average user's shower cleaning device.

Next, when washing the bidet, the water from the tank 1 is guided to the through hole 21a through the hot water tank 5 in the same way as in the case of shower washing, but the switch 38 is
Turn it off. The magnetic force disappears due to the OFF operation, and the first piston body 22 moves forward by the water pressure from the through hole 21a. In this case, the first and second springs 2
Due to the strength of the pistons 3 and 33, the first piston body 22 begins to move after the shoulder portion 32d contacts the stopper 34, and thereafter both piston bodies 22 and 31 move forward as one. For this reason, the second piston body 31 and the nozzle 32 are moved by the length that the first piston body moves (actually about 100 degrees
mm).

In this way, when the nozzle 32 reaches the forwardmost position, the poppet valve 35 opens and the washing water is ejected from the spout 32a at the tip, so that the desired bidet washing can be achieved.

In this case, the water pressure is lower than that during shower cleaning, and various methods of adjusting it can be considered, but in this embodiment, the rotation speed of the pump 3 is changed.

When the user finishes shower cleaning or bidet cleaning and turns off the switches, the urging force of the three springs 23, 33, and 34 acts to close the first piston body 22, the second piston body 31, and the poppet valve 3.
5 returns to the position shown. In this case, the water in the space A is discharged through the through hole 21a, the orifice 29, and the drain line 28, but in this embodiment, the water is further guided to the groove 25a and is made to fall into the nozzle 32. Therefore, the nozzle 32 can be cleaned.

On the other hand, the water in space B flows through the small hole 3 at the bottom of the nozzle tip.
It is discharged to the outside from 2c.

As described above, the present invention has a structure in which an electromagnetic coil is provided at the rear end of the fixed cylinder, and the electromagnetic coil is excited during shower cleaning to magnetically attract the first piston body and fix it to the rear end of the fixed cylinder. Therefore, there is no need to provide water supply pipes to send water pressure to the front and rear of the first piston body, as in the past, and the first piston body can be moved or stopped simply by electrical ON/OFF operation. Further, since the electrical ON/OFF operation is performed, there is no need to worry about leakage from the sealing portion, and therefore, reliable operation can be achieved.
