Abstract

PROBLEM TO BE SOLVED: To prevent water from being unnecessarily spouted out of a washing liquid spout-out hole in the state of storing water in a tank by providing packing for opening/closing the duct of washing liquid corresponding to the turn of a nozzle by forming a duct on a turning shaft part. SOLUTION: When storing washing water in a tank part 4, washing liquid is prevented from being leaked from near a water supply port by an O ring installed around a water supply lid 9. Since packing 12 held on one side of a turning shaft 6 closes the duct of a bearing part 11, water is not spouted out of the spout-out hole at the top end of a nozzle 5 even when a switch is pushed. Next, a switch 7 and the nozzle 5 are pulled out so as to be arranged on a straight line parallelly with a main body 4 while being swung with the base end of the turning shaft 6 as a supporting point. At such a time, the packing 12 held on one side of the turning shaft 6 does not close the duct of the bearing part. Besides, when housing the main body 4, since a shaft seal is provided on the driving shaft of a pump, water is not infiltrated through a gap to the side of a motor 2.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable washer used for washing the vicinity of the anus and the like and generally called a portable washlet or the like.

[0002]

2. Description of the Related Art In recent years, washing machines for washing human body parts have become widespread in order to raise awareness of health and to keep cleanliness. The washer is usually installed on the toilet seat, and a nozzle protruding from the body of the washer swings back and forth, left and right while ejecting washing water toward the user to wash the local area.

Recently, various portable cleaners have been proposed because of the desire to use the cleaner even on the go.
Hereinafter, an example of the portable cleaner will be described.

FIG. 4A is an external view of a conventional portable cleaner, and FIG. 4B is a sectional view of the same. Reference numeral 1 is a battery that serves as a power source for a portable cleaner, 2 is a motor that uses this battery as a power source, and 3 is a gear pump that is driven by the motor, and pressurizes cleaning water. Reference numeral 4 is a main body that incorporates these batteries, a motor, a gear pump, and the like. Reference numeral 5 is a nozzle having an ejection hole for ejecting the cleaning liquid, and 6 is a rotary shaft connecting the nozzle 5 and the main body 4. Reference numeral 7 is a switch provided on the surface of the main body, and a voltage is applied to the motor 2 only while the switch is being pressed to operate the gear pump 3. Reference numeral 8 denotes a resin tank portion that stores a cleaning liquid when used, and the main body 4 is fitted inside when being carried and also functions as a storage case for the main body 4. Reference numeral 9 denotes a detachable water supply lid fitted to a water supply port for supplying the wash water into the tank portion 8, and 10 denotes a water suction port for sending the wash water in the tank portion 8 to the gear pump 3.

The operation of the portable cleaner having the above structure will be described below. First, the main body 4 is pulled out from the tank portion 8 to form a space for storing cleaning water inside the tank portion 8. Next, the nozzle 5 held in the nozzle accommodating portion provided near the side surface of the main body is rotated about the rotation axis 6 as a fulcrum and pulled out to a position parallel to the major axis direction of the main body. More washing water is supplied and the water absorption lid 9 is closed.

When the switch 7 is pressed in this state, the motor 2 is rotated and the cleaning water sucked up by the gear pump 3 is ejected from the ejection hole 5a at the tip of the nozzle 5 through the rotary shaft 6, and the cleaning water locally irradiates the human body. To wash.
After the use, all the cleaning liquid stored in the tank portion 8 is ejected, the nozzle 5 is housed in the side surface of the main body, and the main body 4 is slid in the tank portion 8 to house the main body 4.

[0007]

However, the above-mentioned conventional configuration has the following problems.

That is, when the tank is left with water in it, there is a problem that water leaks from the tip of the nozzle due to a capillary phenomenon, and if the switch is accidentally pressed, water projects. It was

Further, when the main body is housed in the tank portion even if there is residual water in the tank portion, pressure is applied to the pump by the main body portion to be fitted. Residual water will infiltrate from the drive shaft to the motor side, and problems such as rust will occur in the parts that make up the pump. Further, since the tank portion is pressed against each joint portion up to the suction port of the pump, it is necessary to secure the pressure resistance of each joint portion.

Further, since the direction of the central axis of the rotating shaft of the nozzle and the direction of the nozzle ejection hole are the same, when the nozzle is rotated from the side of the main body, the direction of ejection of the washing water is always upward and the angle of the ejection hole is adjusted. Can not be done, and when aligning the cleaning liquid ejection holes,
It was necessary to change the angle of the hand holding the body. Furthermore, when a third party uses this portable washer for an elderly person or an infant, it is difficult to position the local washes. this is,
When the washing water is sprayed to the user who has the upper body facing upward, the spouting direction of the portable cleaning device is upward even though the cleaning water needs to be spouted forward from the user. This is because

On the other hand, since a plurality of nozzles having different ejection hole diameters were used to adjust the amount of the cleaning liquid ejected, the replacement nozzle had to be always carried.

The present invention solves the above-mentioned problems of the prior art by preventing unnecessary spouting of water from the cleaning liquid spouting hole in a state where water is contained in the tank portion, and when there is residual water in the tank portion. An object of the present invention is to provide a portable cleaning device that realizes downsizing when being carried, because the angle of the nozzle or the amount of sprayed cleaning liquid can be easily adjusted without causing problems with the motor or each joint even if the tank part slides. And

[0013]

In order to achieve this object, a portable cleaner of the present invention comprises a nozzle having an ejection hole for ejecting a cleaning liquid, a main body provided with a pump, a motor and a battery, and a main body. And a nozzle for opening and closing the flow path of the cleaning liquid according to the rotation of the rotating shaft, and a multi-stage expandable and retractable tank for storing the cleaning liquid.

The pump is directly attached to the suction port formed in the main body, or the main body and the pump case are integrally formed. The nozzle has a structure in which the angle of the ejection hole can be adjusted in multiple stages, and the packing has a configuration in which the cleaning liquid outflow area can be adjusted by the rotation angle of the nozzle.

With this structure, the packing that opens and closes in accordance with the rotation of the rotation shaft portion causes the flow path to be in the "closed" state when the nozzle is housed, so that even if the capillary phenomenon or the switch is erroneously operated, it is unnecessary from the ejection hole at the tip of the nozzle. It is possible to prevent spouting of a clean cleaning liquid.

Further, by providing the drive shaft with a shaft seal, even when abnormal water pressure is applied to the pump,
The circumference of the drive shaft is waterproof by a shaft seal, and water can be prevented from entering the motor side. Furthermore, when the pump is attached to the cleaning liquid suction port, it is possible to reduce the number of parts and improve the reliability of the joint by directly mounting it without passing through a tube or the like, and by forming the pump case with a part of the main body, the joint Reliability will be even higher.

Further, the nozzle has a rotating shaft, and is constructed so as to be orthogonal to the direction of the rotating center axis and the direction of the nozzle ejection hole, and by giving a click feeling in a multi-step manner, the hand holding the main body It can be used with the desired nozzle angle without changing the angle.

Further, the packing can change the contact area with the flow path according to the rotation angle of the rotating shaft, and adjust the flow rate depending on the open / closed state of the flow path.

The operation of the portable cleaner having the above structure will be described in detail. First, the main body 4 is pulled out from the tank portion 8. Next, the water supply lid 9 is opened, and the cleaning liquid is added from the rear of the tank. Then, the water supply lid 9 is closed and the cleaning water is stored in the tank unit 4. At this time, the O-ring installed around the water supply lid 9 prevents the cleaning liquid from leaking from the vicinity of the water supply port.

Since the packing 12 held on one side surface of the rotating shaft 6 blocks the flow path of the bearing portion 11 as shown in FIG. 3D, even if the switch 7 is pressed, the tip of the nozzle 5 is There is no water spouting from the spout. Next, the base end of the rotary shaft 6 is oscillated as a fulcrum, and the switch 7 and the nozzle 5
Pull out until they line up in a straight line.

At this time, FIGS. 3 (a), 3 (b) and 3 (c)
As shown in, the packing 12 held on one side surface of the rotating shaft 6 does not block the flow path of the bearing portion. When the switch 7 is pressed in this state, when voltage is applied to the motor 2,
The cleaning liquid is sucked up by the gear pump from the water suction port 10. Rinse the cleaning water pressurized by the pump to the bearing 11.
Enters from the direction and is delivered to the ascending / descending where the rotating shaft 6 is located
It is ejected from the tip ejection hole 5a of the nozzle 5.

After all the cleaning liquid in the tank portion 8 has been ejected,
The main body 4 is housed in the tank portion 8 by rotating the rotary shaft 6 to rotate the nozzle 5 on the main body in the P direction in FIG. 2 and sliding the main body in the Q direction. At this time, the drive shaft 1 of the pump
Since 6 is provided with the shaft seal 17, water does not enter the motor 2 side through the gap. In addition, pump 3
Is directly inserted into the main body water intake port 10 via an O-ring, and there is little risk of water leakage even when water pressure is applied.

The risk of water leakage can be reduced by directly attaching to. Further, as shown in FIG. 5, the angle of the hand holding the main body is the same, the ejection direction can be freely set, and as shown in FIG. 7, the other person's local area can be easily washed.

Although the pump case 13 of the gear pump 3 is directly attached to the main body 4 in the embodiment, it goes without saying that the pump case 13 may be formed of the main body 4.

Further, although the rotary shaft 6 is simply rotated, click feeling may be provided in multiple stages so that the nozzle 5 can be fixed at each stage. Alternatively, the packing 12 is set to be closed only when the nozzle 5 is stored.
2 may have a structure in which the flow path is gradually narrowed as the rotary shaft 6 rotates.

Further, in the embodiment, the tank portion 8 is 1
Although it has been stored in multiple tiers, the tank section 8 has an expandable structure of two or more tiers so that even when the tank section has a large capacity,
It can be made smaller according to the downsizing of the body, which is more effective for carrying.
