China Utility Model No. CN2559699Y Specification

The conventional technology has a drawback in that the quality of the oil blocking bad odor from the urine water of the urinal body deteriorates and the bad odor blocking effect disappears. In addition, the use of oil that should not be discharged to the outside is not inherently preferable.
The present invention is a non-water-washing structure that can be easily replaced or cleaned by deodorizing without using (blocking) oil that prevents the odor of urination water from being released so as to solve such problems of the prior art. It aims at providing a type urinal deodorizing device.
The present invention suppresses the generation of ammonia that does not freeze urine water even in cold regions or during cold weather, does not generate urinary stones, and propagates germs that live inside urine stones and generates odors. It is an object of the present invention to provide a non-water-washing urinal deodorization device that does not generate a bad odor of ammonia.

Specific means for solving the problems in the non-washing urinal deodorization apparatus of the present invention are as follows.
That is, a funnel-like urinary duct fitted into the urine outlet at the bottom of the urinal body, and a urinary duct valve attached to the lower urine outlet of the funnel-like urinary duct. It is formed in a flat tube shape with an elastic material, the inside of this flat tube shape is a urine passage, and the opposing wall surface forming this urine passage is always closed elastically, The urination water passage is opened by being expanded and deformed against the elasticity.

Thereby, when urinating without urination water, bad odor such as urination water does not drift out from the urine outlet at the bottom of the urinal body, and during urination, a urination water passage is formed in the urinary duct valve.
Moreover, it is preferable that the lower urination port of the funnel-shaped urinary duct is an opening having an oval cross section with acute angles at both ends.
Thereby, at the time of urination, the urination water is easily discharged from the lower urination port of the funnel-shaped ureter to the urine passage of the ureter valve.
The funnel-like urinary duct is provided with a guide member that pushes the urinary duct valve from the side to hold the urine passage in a closed state.

The guide member reliably prevents a bad odor from drifting out from the urination opening at the bottom of the urinal body when not urinating.
The guide member is preferably provided with a heater. As a result, the urination water passage opens and the urine water is discharged without freezing even in cold districts or in cold weather.
The funnel-like urinary tract fitted with the ureter valve is housed in an inner cylinder having an opening at the bottom, and the inner cylinder is housed in an outer cylinder having an opening at the bottom. It is fitted to the urination port at the bottom of the toilet body.

Thereby, the non-water-washing urinal deodorization apparatus itself of this invention can be replaced or cleaned easily.
Further, the inner cylinder has an overflow pipe erected at the center of the bottom, and a filling chamber of a microorganism implantation base material is formed between the overflow pipe and the inner cylinder, and is discharged from the urination pipe valve. It is preferable that the discharged urine water is stored in the filling chamber of the microorganism-implanted base material and then overflows from the top of the overflow pipe and is discharged from the opening at the bottom of the outer cylinder.
As a result, urine is not generated in the urine passage and the urine is discharged smoothly, and the odor of ammonia caused by bacteria that settle inside the urine is not generated.

  According to the present invention, by providing a funnel-like urinary duct and a urinary duct valve attached to the lower urinary outlet of the funnel-like urinary duct, the urine water is discharged from the urine outlet at the bottom of the urinal body when not urinating. The urine water passage can be formed at the time of urination, and the water saving effect is increased because it is not a flush type. Furthermore, the heater of the guide member can withstand use in a cold region, urine stones are not generated in the passage of urine water, etc., and the discharge of urine water is smooth, and there is no odor of ammonia.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The urinal deodorizing apparatus 1 according to the present embodiment includes a funnel-like urinary tube 2 and a urine valve 3 attached to a lower urine outlet 21 of the funnel-like urine tube 2, and urinates at the bottom of the urinal body 20. It is fitted to the mouth 20a. This funnel-shaped urinary canal 2 is provided with a guide member 4 which is further accommodated in an inner cylinder 5 which is accommodated in an outer cylinder 6 (FIG. 1).
As shown in the front view of FIG. 2 and the partial cross-sectional side view of FIG. 3, the funnel-shaped urinary duct 2 has an upper portion 22 formed with a ring having a diameter larger than that of the lower portion 23. It has a shaped connecting portion 24 (funnel shape). And the lower part 23 of the annular | circular shape of the funnel-shaped urination tube 2 is similarly connected to the lower urine outlet 21 by the morning glory-shaped connection part. As shown in the bottom view (FIG. 4), the lower urination port 21 is an opening 21 c in which both ends 21 a and 21 b have an elliptical cross section with an acute angle.

The urinary duct valve 3 is made of an elastic material such as rubber. It is not limited to rubber such as a flexible elastic elastomer, but may be plastic. As shown in FIGS. 2 and 3, the urinary duct valve 3 has a flat tube shape. As shown in FIG. 2, the urinary duct valve 3 is rectangular, but is not limited to a rectangular shape and may be trapezoidal or square.
The urinary tube valve 3 has a tube shape having openings 32a of the urine water passage 32 at both ends 33a and 33b. That is, the inside of the flat tube-like urine drainage valve 3 becomes the urine water passage 32, and the opposing wall surfaces 31a and 31b forming the urine water passage 32 are always elastically closed as shown in FIGS. It is as follows.

At one end 33 a of the urinary tract valve 3, the opening 32 a that is the urine drainage passage 32 is opened wide and attached to the lower urination port 21 of the funnel-shaped urinary tract 2. This wearing situation is shown in FIG. A projection 21d is provided slightly above the lower end 21e of the lower urination port 21 so as to wrap around the outer periphery of the lower urination port 21, and one end 33a of the urinary tube valve 3 is connected to the lower urination port 21 above the projection 21d. If attached to the urine valve, it is possible to prevent the urinary duct valve 3 from falling out of the lower urination port 21.
A guide member 4 is provided on the funnel-shaped urinary canal 2 (FIG. 6). The guide member 4 is made of rubber or the like, but is not limited to rubber. The guide member 4 has a front part 44 and a back part 45. As shown in FIG. 2 (FIG. 3), the front portion 44 of the guide member 4 is provided with two reinforcing bars 41 a and 41 b in the vertical direction on the surface (on the side opposite to the back portion 45), and below the front portion 44. As shown in FIG. 3, the inclination is slightly inclined toward the back face 45. Further, a fitting groove 42 is provided in the horizontal direction on the back surface 45 side above the front surface 44.

As shown in the side view of FIG. 3, the back surface portion 45 of the guide member 4 lacks a portion corresponding to the lower slope of the front surface portion 44, and a notch groove 43 is provided in the horizontal direction at the upper center of the back surface portion 45. It has been.
