Description

  The present invention relates to a portable local washer for washing a local part after stool, and more particularly, to a portable local washer that can wash the local part using a PET bottle.

  Washlet-type toilets that can be washed locally after use are often used in general households, but the washlet-type toilets are often not installed in travel destinations and public toilets, and earthquakes, etc. In the event of a disaster, even a washlet-type toilet may not be used due to a power outage or stoppage of water supply.

  Therefore, in recent years, a portable local washer has been developed as a device that can wash the local area after the toilet even without a washlet-type toilet in the toilet.

  As such a portable local washer, for example, a portable storage tank in which cleaning water is stored, a fountain pipe that guides the stored water in the storage tank to the outside, and a tip of the fountain pipe are provided. And a nozzle part capable of fountain spraying toward the local part, and driving the pump with electric power from a dry battery or the like, causing the cleaning water in the storage tank to fountain from the nozzle part and cleaning the local part. There was a portable local washer (see, for example, Patent Document 1).

  In addition, a manual portable local washer is also proposed in which the internal reservoir water is sprayed from the nozzle portion by manually pressing the storage tank from the outside to perform local cleaning (for example, Patent Document 2). reference.).

  However, in these portable local washer, if a dedicated storage tank, and an integrated fountain pipe and nozzle portion are not carried and prepared in advance, use them. It is inconvenient.

  On the other hand, most of PET bottles are disposed of when their contents disappear. However, since the amount of discarded PET bottles is large, it is one of the garbage problems.

Therefore, the present applicant does not need to carry a dedicated storage tank in order to solve such a problem, and uses a discarded plastic bottle as a storage tank and can be connected to this plastic bottle. Has already been filed (for example, see Patent Document 3).

  According to this portable local washer, it has been well received that it can recycle discarded plastic bottles and reduce the garbage problem. However, this portable local washer has the following problems. It was.

  In other words, the diameter, height, etc. of the mouth part of the plastic bottle used in beverages sold by each manufacturer are not the same, and the size differs slightly for each manufacturer. However, the portable local washer developed by the company has a problem in that PET bottles having different mouth sizes cannot be successfully connected to the nozzle device.

  An object of the present invention is to provide a portable local washer that can easily and reliably connect a nozzle device even for PET bottles having different mouth sizes.

  In order to achieve the above object, a portable local washer according to the present invention is provided with a nozzle device that fountains the stored water stored in the PET bottle through the water pipe at the mouth of the PET bottle. In the portable local washer, a cylindrical elastic body that can be inserted into the mouth and can be expanded and reduced, and penetrates the lower end surface from the inside of the nozzle device. A shaft portion protruding downward and a seat plate portion fixed to the lower end of the shaft portion are provided, and the shaft portion is passed through the elastic body and between the lower end surface of the nozzle device and the seat plate portion. In a sandwiched state, the elastic body is connected by a connecting shaft in the vicinity of the upper end of the shaft portion of the diameter expanding means, and a diameter expanding means for compressing and expanding the elastic body in the vertical direction of the shaft portion. And an operating portion that allows the elastic body to be compressed by moving the shaft portion in the vertical direction. Characterized in that it was.

  According to the present invention, since the elastic body inserted into the mouth portion of the plastic bottle is enlarged in diameter only by operating the operation portion, the mouth portion is sealed. Even if the PET bottles are different, each PET bottle can be easily and reliably connected to the nozzle device.

  Hereinafter, a portable local washer according to the present invention will be described with reference to the drawings.

  FIG. 1 is an overall perspective view showing an embodiment of a portable local washer A according to the present invention, and FIG. 2 is an exploded cross-sectional view of a main part in which a dotted line part in FIG. 1 is enlarged.

  This portable local washer A is provided with a nozzle device Q for spraying the stored water W stored in the PET bottle P through the water pipe Q1 at the mouth portion P1 of the PET bottle P. An elastic body 1 that can be inserted into the mouth portion P1 and that can expand and reduce the diameter of the mouth portion P1, and a diameter expanding means 2 that compresses and expands the diameter of the elastic body 1. The operation part 3 which moves the axial part 21 of this diameter expansion means 2 to an up-down direction is comprised.

  Hereinafter, each member will be described in detail.

  The elastic body 1 is made of a material such as rubber, cork, and silicon in a cylindrical shape so that the diameter can be increased and reduced, and the cylindrical outer diameter can be inserted into the mouth portion P1 of the plastic bottle P. Thus, the inserted elastic body 1 is compressed by the diameter expanding means 2 to seal the mouth portion P1.

  Specifically, a hollow shaft portion 21 inserted in the nozzle device Q is passed through the elastic body 1, and a seat plate portion 22 having substantially the same diameter as the elastic body 1 is formed at the lower end of the shaft portion 21. The elastic body 1 is sandwiched between the seat plate portion 22 and the lower end surface Q2 of the nozzle device Q.

  Further, a connecting shaft 23 penetrating the base end of the operation unit 3 is provided near the upper end of the shaft unit 21, and is connected to the operation unit 3.

  The seat plate portion 22 is provided with a water reverse pipe 31 through which the stored water W passes through the shaft portion 21, and a reverse support valve 31 that can be ventilated only in the plastic bottle P along with the water flow pipe Q 1. The stored water W in the plastic bottle P can be drained.

  As long as the stored water W in the plastic bottle P can be fountained through the water pipe Q1, a simple vent hole may be provided instead of the reverse support valve 31.

  In addition to the so-called lever method as shown in the present embodiment, the diameter expanding means 2 is a well-known mechanism such as a screw tightening method in which a screw is tightened with the shaft portion 21 as a screw shaft. Can be adopted.

  There are various shapes and capacities of the plastic bottle P. However, the shape and capacity are not limited, and as described above, the elastic body 1 and the lower member 3 are disposed in the mouth portion P1 of the plastic bottle P. What is necessary is just to be formed so that insertion is possible.

  The portable local washer A of the present invention configured as described above can be carried compactly if it is stored in a bag or the like, and is used in the following manner.

  First, when using the portable local washer A of the present invention, obtain an empty plastic bottle P to be discarded and store the stored water W such as tap water or cleaning liquid in the plastic bottle P, Alternatively, after purchasing a commercially available plastic bottle P stored with drinkable stored water W and removing the bottle cap, an elastic body having a reduced diameter in the mouth portion P1 of the plastic bottle P 1 is inserted together with the seat plate portion 22 and inserted, and the upper end P1a of the mouth portion P1 is joined to the lower end surface Q2 of the nozzle device Q.

  Next, when the operation unit 3 is pushed down and operated as indicated by an arrow in the figure, the shaft portion 21 is lifted by the cam mechanism 24 of the operation portion 3, and the seat plate portion 22 is moved upward via the shaft portion 21. Be raised.

  Therefore, the elastic body 1 sandwiched between the lower end surface Q2 of the nozzle device Q and the seat plate portion 22 is compressed from the up and down direction, so that it tends to expand in the diameter increasing direction. Since it is regulated by the inner wall surface of the mouth portion P1, the elastic body 1 presses and adheres to the inner wall surface of the mouth portion P1, completely seals the mouth portion P1, and the stored water W in the plastic bottle P is opened. It is possible to completely prevent water leakage from the part P1.

  And if a user starts the nozzle apparatus Q after a stool, the stored water W in the PET bottle P will be sprayed from the front-end | tip of the nozzle apparatus Q through the water pipe Q1, and a local part can be wash | cleaned.

  Thus, according to the present invention, the elastic body 1 inserted into the mouth part P1 of the plastic bottle P is compressed and expanded in diameter only by operating the operation part 3, and the mouth part P1 is sealed. Since it has a structure, even if it is a PET bottle P having a different size of the mouth portion P1, each PET bottle P can be easily and reliably connected to the nozzle device Q, and the discarded PET bottle P can be reused. As a result, the problem of garbage caused by the plastic bottle P can be reduced.

  FIG. 3 is an exploded cross-sectional view of the main part showing another embodiment of the diameter expanding means 2.

  Here, the same reference numerals are given to members common to FIGS. 1 to 3, and redundant description is omitted, and only the features of the present embodiment will be described below.

  That is, in the diameter expanding means 2, a hollow shaft portion 21 inserted in the nozzle device Q is a screw shaft having a screw thread 23 on the outer periphery, and the shaft portion 21 penetrates the elastic body 1. The seat plate 22 having substantially the same diameter as the elastic body 1 is fixed to the lower end of the shaft portion 21, and the elastic body 1 is sandwiched between the seat plate 22 and the lower end surface Q 2 of the nozzle device Q.

  On the other hand, a disk-like operation portion 3 having a thread groove 31a screwed into the shaft portion 21 is screwed into the shaft portion 21 in the nozzle device Q from above the shaft portion 21. The shaft portion 21 is moved up and down by rotating the portion 3.

  Further, Q3 in the figure indicates an opening for rotating a part of the disk-shaped operation unit 3 from the outside of the nozzle device Q, and the operation unit 3 can be rotated by a finger from the outside of the opening Q3. I am doing so.

  Note that the outer peripheral side surface of the operation unit 3 is preferably knurled so as not to slip with a finger.

  Also in the portable local washer A equipped with such a diameter expanding means 2, the elastic body 1 in a reduced diameter state is inserted into the mouth portion P1 of the plastic bottle P together with the seat plate portion 22 as described above, and the mouth portion The upper end P1a of P1 is joined to the lower end surface Q2 of the nozzle device Q.

  Next, when the disk-shaped operation part 3 is rotated in the left or right direction in the circumferential direction, the thread groove 31a of the operation part 3 is screwed into the screw thread 23 of the shaft part 21. Therefore, the seat plate portion 22 is pulled upward.

  Therefore, the elastic body 1 sandwiched between the lower end surface Q2 of the nozzle device Q and the seat plate portion 22 is compressed from the up and down direction, so that it tends to expand in the diameter increasing direction. Since it is regulated by the inner wall surface of the mouth portion P1, the elastic body 1 presses and adheres to the inner wall surface of the mouth portion P1, completely seals the mouth portion P1, and the stored water W in the plastic bottle P is opened. It is possible to completely prevent water leakage from the part P1.

  And if a user starts the nozzle apparatus Q after a stool, the stored water W in the PET bottle P will be sprayed from the front-end | tip of the nozzle apparatus Q through the water pipe Q1, and a local part can be wash | cleaned.

  Thus, according to the present invention, the elastic body 1 inserted into the mouth part P1 of the plastic bottle P is compressed and expanded in diameter only by operating the operation part 3, and the mouth part P1 is sealed. Since it has a structure, each plastic bottle P can be easily and reliably connected to the nozzle device Q even if the size of the mouth portion P1 is different, and the discarded plastic bottle P is reused. As a result, the problem of garbage caused by the plastic bottle P can be reduced.

It is the whole perspective view showing one example of portable local washing machine A concerning the present invention. FIG. 2 is an exploded cross-sectional view of a main part in which a dotted line part in FIG. 1 is enlarged.
