Description

  The present invention relates to a simulated urine ejection device.

  Conventionally, in public toilets and men's toilets in commercial facilities, a urinal specialized in standing urination and a toilet are often provided. On the other hand, Western toilets are installed in many household toilets because of the installation area. In such a Western-style toilet, when urinating in the standing position of a man, the urine does not stay in the toilet bowl but is scattered on the upper part of the rim, the toilet lid, etc., and it is difficult to clean the toilet. It has become. Moreover, the scattered urine not only gives off a bad odor but also adheres as a urine stone, which is not only unfavorable for hygiene but also impairs the appearance of the toilet.

  For the purpose of solving such problems, Western-style toilets with less urine scattering during urination while standing in men have been studied. For this purpose, evaluation of urine scattering and scattering suppression is required.

  Therefore, conventionally, in order to achieve the same or similar appearance of urination due to urination while standing in a male position, a liquid such as tap water or colored water is used as a simulated urine. In both cases, simulated urine is discharged from a syringe or pipette manually. However, such a method for discharging simulated urine has a large variation due to manual operation, and it has not always been easy to evaluate and analyze the distribution and amount of urine scattering accurately. In addition, it has been attempted to discharge and scatter simulated urine into the ball of a Western-style toilet through a hose suspended above the Western-style toilet. It is hard to say that the same situation has been successfully achieved.

  By the way, the present inventors have determined the discharge position for a Western-style toilet corresponding to changes in the amount and speed of discharge of a simulated stool and the position of a person's anus, which have been necessary for evaluating the washability of a Western-style toilet. An invention of a simulated fecal discharge device that enables adjustment is proposed (see Patent Document 1).

  The simulated stool discharge apparatus described in Patent Document 1 includes a discharge unit having a discharge port portion and a pressing portion that pushes out the simulated stool that is accommodated in communication with the discharge port portion, and the discharge port portion of the toilet port is a toilet. And a discharge unit support that supports the ball so as to be positioned above the ball. With this feature, a simple simulated stool discharge device that discharges simulated stool from above into the bowl of the toilet bowl is realized, and the evaluation reproducibility is enhanced.

  However, heretofore, no simulated urine ejection device required for evaluation of urine scattering and scattering suppression has been proposed.

  The present invention has been made in view of the circumstances as described above, and is a simulated urine capable of realizing the same or similar appearance of urine scattering when a man stands and uses a Western-style toilet. It is an object to provide a discharge device.

In order to solve the above problems, a simulated urine discharge device of the present invention is a simulated urine discharge device for discharging simulated urine imitating human urine into a Western-style toilet, and a tank for storing the simulated urine; A discharge port portion at the tip, a discharge device for discharging the simulated urine into the Western-style toilet from the discharge port portion, a communication path for communicating the tank and the discharge device, and a middle of the communication path A pressure-feeding means for sucking the simulated urine from the tank and feeding it to the discharge device, and supporting the discharge port portion of the discharge device facing the inner surface of a ball provided in the Western-style toilet A support body, and the discharge port portion includes a base portion having a circular cross section and a flat portion, and has a tapered shape in which the diameter gradually decreases from the base portion to the flat portion, and a distal end of the discharge port portion is a flat opening.

  FIG. 1 is a schematic view showing an embodiment of the simulated urine ejection device of the present invention.

  As shown in FIG. 1, the simulated urine discharge device 1 is a simulated urine discharge device 1 that discharges simulated urine 2 imitating human urine into a Western-style toilet 3, and a tank 4 that stores the simulated urine 2. A discharge port portion 5 at the tip, a discharge device 6 for discharging the simulated urine 2 into the Western-style toilet 3 from the discharge port portion 5, a communication path 7 for communicating the tank 4 and the discharge device 6, A pressure feeding means 8 that is provided in the middle of the communication path 7 and sucks the simulated urine 2 from the tank 4 and feeds it to the discharge device 6, and a discharge port portion 5 of the discharge device 6 includes a ball 9 provided in the Western-style toilet 3. And a support body 10 that is opposed to and supported by the inner surface.

  The simulated urine 2 applied in the simulated urine discharge device 1 is defined as a liquid imitating human urine. As the simulated urine 2, for example, tap water or water colored with food coloring or the like is applicable.

  The simulated urine 2 is stored in the tank 4 until it is subjected to the scattering test. The simulated urine 2 prepared outside the tank 4 can be poured into the tank 4 and stored inside the tank 4. When tap water is used as the simulated urine 2, it is also possible to supply and store the tap water continuously to the tank 4 by directly connecting the tank 4 and the water pipe.

  In the simulated urine discharge device 1, the tank 4 and the discharger 6 are communicated with each other through the communication path 7. Further, a pressure feeding means 8 is provided in the middle of the communication path 7. The simulated urine 2 stored in the tank 4 as described above is sucked from the tank 4 by the pressure feeding means 8, is fed toward the discharge device 6 through the communication path 7, and is detachably provided at the tip of the discharge device 6. The simulated urine 2 is discharged from the discharge port 5 into the western toilet 3.

  The pressure feeding means 8 is not particularly limited as long as it is normally used for sucking and feeding liquid, and examples thereof include a low flow rate pump.

  Further, the simulated urine discharge device 1 supports the discharge port portion 5 of the discharge device 6 by the support 10 so as to face the inner surface of the ball 9 provided in the western style toilet 3. The support 10 can freely adjust the height and angle of the discharge port portion 5 of the discharger 6 and can fix the discharger 6 at a position optimal for the scattering test.

  The support 10 includes a stand-type column 10a and one or a plurality of horizontal bars 10b connected to the stand-type column 10a.

  The horizontal bar 10b can fix the discharger 6 at one end. Examples of the horizontal bar 10b include one in which one end is a fixture such as a clamp shape or a muff shape. As the horizontal bar 10b, a commercially available fixture such as a clamp or a muff is applicable.

  In addition, the horizontal bar 10b can be slid back and forth or up and down with respect to the stand-type support 10a, and the discharger 6 can be fixed at an arbitrary position. Further, the horizontal bar 10b can freely rotate and rotate in the left-right direction. Since such slide and rotation are possible, the height position and angle of the discharge port portion 5 of the discharger 6 can be adjusted.

  In addition, about the height position of the discharge port part 5, it is preferable that it is the height equivalent to the position of the urethral opening when a man stands and uses the western style toilet 3 for small use.

  Further, the position adjustment of the discharger 6 on the support 10 may be manual or automated. The simulated urine discharge device 1 is equipped with an imaging device such as a monitor camera or a sensor device for recording the amount of simulated urine 2 scattered or the simulated urine scattering portion of the Western-style toilet 3 as an image or video. Good.

  In the simulated urine discharge device 1, the flow rate adjusting means 12 that adjusts the discharge amount of the simulated urine 2 from the discharge port portion 5 in the middle of the communication path 7, and the simulated urine 2 from the discharge port portion 5 after a predetermined time has elapsed. It is preferable that a stop means 13 for stopping the discharge is also provided.

  The flow rate adjusting means 12 can adjust the discharge amount of the simulated urine 2 within the range of the amount of urination per man. As the discharge amount, for example, an amount of about 250 ml is exemplified.

  The flow rate adjusting means 12 is not particularly limited as long as it is normally used for liquid flow rate adjustment, and examples thereof include a valve. As the flow rate adjustment by the flow rate adjusting means 12, either manual adjustment or automatic adjustment can be applied. However, in consideration of the reproducibility of the scattering test of the simulated urine 2, the automatic adjustment is preferable.

  The stop means 13 can adjust the discharge time of the simulated urine 2 within the range of the male urination time per one time, and can stop the discharge of the simulated urine 2 from the discharge port 5 after a predetermined time has elapsed. Examples of the predetermined time include a time of about 12 seconds.

  The stopping means 13 is not particularly limited as long as it is normally used for liquid flow rate adjustment, and examples thereof include an electromagnetic valve. When an electromagnetic valve is used as the stopping means 13, it is possible to automatically stop the discharge of the simulated urine 2 immediately after a predetermined time has elapsed by timer control.

  FIG. 2 is a perspective view of the discharge port portion of the simulated urine discharge device of the present invention. FIG. 3A is a schematic cross-sectional view of the discharge port portion of FIG. FIG. 3B is a schematic front view of the opening of the discharge port portion of FIG.

  As shown in FIGS. 2 and 3A, the discharge port portion 5 includes a base portion 14 and a flat portion 15 having a circular cross section, and has a tapered shape whose diameter gradually decreases from the base portion 14 to the flat portion 15. Moreover, as shown in FIG.3 (b), the front-end | tip of the discharge outlet part 5 is the flat opening 11, and the ratio of the width | variety of the short side of the opening 11 and the width | variety of the long side is 1: 3-1. : Within the range of 10. If the ratio of the width on the short side to the width on the long side is within the above range, as shown in FIG. 4, the water flow of the simulated urine 2 discharged from the opening 11 is twisted, and the male stands up to the Western style. A state similar to or similar to the state when the toilet 3 is used for small items can be realized.

  When the simulated urine 2 is discharged from the tip of the discharge port portion 5 which is such a tapered and flat opening 11, a large spiral twist is generated in the simulated urine 2, as shown in FIG. Then, when the simulated urine 2 with a large twist lands on the water surface on the inner surface of the ball 9 of the Western-style toilet 3, the disturbance of the water surface and the scattering of the simulated urine 2 increase.

  As a width | variety of the short side of the opening 11, the range of 0.5-2.0 mm is illustrated, for example. Examples of the width on the long side of the opening 11 include a range of 4 to 8 mm. As long as the width on the short side and the width on the long side are within the above ranges, it is possible to realize the same state as or similar to the state when the western toilet 3 is used for standing.

  In addition, the opening 11 may be arranged in a front view vertically long or in a front view horizontally long when used, but it is preferably arranged in a front view vertically like a male urethral opening. .

  The diameter of the base portion 14 of the discharge port portion 5 is preferably larger than the cross-sectional area of the opening 11 and is, for example, in the range of 4 to 12 mm. Moreover, as the length of the flat part 15 in the front-end | tip of the discharge outlet part 5, the range of 5-10 mm is illustrated, for example.

  The material of the discharge port portion 5 is not particularly limited as long as it can be processed into a desired shape, and examples thereof include resin and glass. As the resin, for example, use of a highly transparent resin such as an acrylic resin is considered.

  The simulated urine ejection device of the present invention is not limited to the above embodiment. Various details of the configuration such as the pressure feeding means, the support, the flow rate adjusting means, and the stopping means are possible.

  Examples are shown below, but the simulated urine ejection device is not limited to the examples.

(Example)
The opening at the front end is a flat opening having a width of 1.0 mm on the short side and a width of 6.0 mm on the long side, and the opening is a front surface with a cross-sectional area of the opening of 6.0 mm ^2. It was attached to the tip of the dispenser so as to be vertically long. The discharger was fixed to the support so that the height from the floor was 75 cm. 1 L of tap water was stored in the tank as a simulated urine. The flow rate adjustment valve was adjusted so that the discharge amount of the simulated urine was 250 mL in 12 seconds, and a timer was set so that the solenoid valve was closed 12 seconds after the discharge of the simulated urine. Raise the toilet lid of the Western-style toilet (Arauno S, manufactured by Panasonic Corporation) to expose the upper surface of the rim, and attach a wetness detection sheet that discolors the water-attached part to the toilet lid and the upper surface of the rim. Simulated urine was discharged with the discharge port portion of the discharger facing the inner surface of the toilet bowl.
(Comparative example)
Simulated urine was discharged in the same manner as in the example except that the opening at the tip of the discharge port was circular in cross section.

About the simulated urine discharge device of the Example and the comparative example, the scattering test of the simulated urine was performed and the following items were evaluated. In addition, the results were compared with the results when a male monitor stood on a Western-style toilet.
<Dispersion ratio of simulated urine to each part of Western toilet>
The positions of the discharge device and the discharge port were adjusted, and the simulated urine was discharged so that the simulated urine landed on the center of the water surface of the ball inner surface of the Western-style toilet. The proportion of the simulated urine splashed to each part of the Western-style toilet bowl was measured based on the amount of discoloration of the water wetting detection sheet.

  The evaluation results are shown in FIG.

  As shown in FIG. 5 (a), when a male monitor stood and used a Western-style toilet, 57% of urine scattering was on the rim upper surface and 43% was a toilet lid. In the simulated urine discharge device of the embodiment in which the tip of the discharge port portion is a flat opening, as shown in FIG. 5B, 55% of the scattering of the simulated urine is the upper surface of the rim and 45% is the toilet lid portion. Met. On the other hand, in the simulated urine discharge device of the comparative example in which the tip of the discharge port portion is an opening having a circular cross section, as shown in FIG. 5C, 73% of the scattering of the simulated urine is the upper surface of the rim, and 27% It was the toilet lid surface. Therefore, when the tip of the discharge port is a flat opening, it is more similar to the appearance of urine scattering when a man stands and uses a Western-style toilet. It was confirmed that can be realized.
