Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a portable local cleaning device.

[0002]

2. Description of the Related Art In recent years, with the rapid spread of a local cleaning device fixed to a toilet device, a cleaning water spouting nozzle, a cleaning water storage tank, and other cleaning devices are provided so that local cleaning can be performed even in a toilet device without such equipment. Various proposals have been made in order to put into practical use a portable local cleaning device having a built-in electric pump for pumping water from a tank to a nozzle and a power source for driving this pump.

[0003]

By the way, in this type of apparatus, since the washing water is continuously jetted from the nozzle for a certain period of time, the power consumption required for driving the pump is inevitably large. Therefore, it is relatively large. A capacity power supply is required. Therefore, when a dry battery is used as the driving power source, a large-capacity dry battery is required, and moreover, the battery needs to be replaced frequently, so that not only is it troublesome to replace the battery, but also the battery runs out. In some cases, there is a problem that the device cannot be used.

On the other hand, when a storage battery is used in place of the dry battery, the number of times of charging increases depending on the frequency of use of the device, and thus the labor required for charging is also great.

In addition, in order to build a large capacity power supply together with the pump, it is inevitable that the device becomes large and heavy.
Not only is the usability poor, but there is also the drawback that the cleaning time is short for the size of the device because the proportion of the storage tank in the entire device decreases.

[0006] Therefore, an object of the present invention is to provide a portable local cleaning device capable of pressure-feeding a cleaning liquid to a nozzle without using an electric pump.

[0007]

In order to achieve the above object, the portable local cleaning apparatus of the present invention is portable, and has a storage space for storing a cleaning liquid for local cleaning in a housing. In the local cleaning apparatus, in the storage space, a cleaning liquid outlet provided as an outlet for the cleaning liquid at one end thereof, and a piston member for pressing the entire surface of the cleaning liquid from the end facing the cleaning liquid outlet to the cleaning liquid outlet. And a spring member urging the piston member in the direction of the cleaning liquid spouting port.

[0008]

According to the portable local cleaning apparatus of the present invention, since the cleaning liquid in the storage tank is pressure-fed to the cleaning liquid discharge port by the piston member, it is not necessary to use the electric pump. .

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

The cleaning liquid discharge port 21 is closed.

The nozzle 2 has a plurality of jets 22 formed at the tip thereof so as to communicate with the cleaning liquid pressure-feeding pipe 20. The cleaning liquid pressure-fed from the opening / closing valve 4 side through the cleaning liquid pressure-feeding pipe 20 has a respective jetting port. It is injected from 22 in a predetermined direction.

While the operation button 5 is being pressed, the cleaning liquid discharge port 21 continues to be closed via the valve rod 16 and the locking spring member 13 is provided inside the piston rod 11 with respect to the controller section (not shown). It is configured to output a command signal for immersing in the valve. When the pressing is released, the valve rod 16 is returned to the position shown in the figure and the output of the command signal is stopped.

The piston mechanism 7 includes a coil spring 15 while the piston rod 11 continues to press the operation button 5.

The engagement is realized, and the space area serving as the cleaning liquid storage chamber is maximized. On the other hand, the opening / closing valve mechanism 4 is returned to the original position shown in FIGS. 1 and 2 by the release of the pressure, and as a result, the cleaning liquid discharge port 21 is opened.

In this state, the cleaning liquid replenished from the cleaning liquid replenishing port 8 by removing the cap (not shown) is stored in the cleaning liquid storage chamber area. After confirming that the inside of the cleaning liquid storage chamber area is filled with the cleaning liquid, the cleaning liquid replenishing port 8 is closed by the cap (not shown), and the ejection port 22
When the locking spring member 13 is retracted into the piston rod 11 manually or by pressing the operation button 5 after positioning the device toward the local area of the device user, the above engagement is released, and in the above-described mode. A predetermined amount of cleaning liquid will be ejected from the ejection port 22.

According to the above configuration, the coil spring 15
The cleaning liquid is pressure-fed to the nozzle 2 by the urging force of the
Since it is possible to inject the cleaning liquid, the electric pump as a means for pumping the cleaning liquid is unnecessary. Therefore, since it is not necessary to incorporate a power source (battery) for driving the electric pump as well as the electric pump, a large space area for storing the cleaning liquid in the casing 1 can be taken, so that long-time cleaning is possible. It is possible.

Further, since it is not necessary to provide a cleaning liquid pressure-feeding means such as an electric pump, the number of parts can be reduced and the cost of the apparatus can be reduced.

Further, since the locking spring member 13 is provided, the cleaning liquid can be started at any timing after the cleaning liquid is replenished.

Further, when the opening / closing valve mechanism 4 is closed by the driving means (ie, the operation button 5), the locking spring member 1
Since 3 is configured to be recessed in the piston rod 11, the operation of pulling out the piston rod 11 can be easily performed.

A window on the slit may be formed by a transparent member at an appropriate portion of the casing 1 so that the amount of the stored cleaning liquid can be visually recognized. Further, the injection pressure of the cleaning liquid ejected from the ejection port 22 can be changed to a desired injection pressure by replacing the coil spring 15 with one having a different biasing force.

FIG. 4 is a partially cutaway sectional view showing the overall construction of a portable local cleaning apparatus according to the second embodiment of the present invention.

In the apparatus according to this embodiment, the cleaning liquid pressure feed pipe 27 communicating with the nozzle 23 is biased to the left in FIG. 4 by the cylindrical first casing 21 extending inward from the left side in FIG.
