  Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. The following description and the accompanying drawings are presented for a general understanding of the present invention, and the technical scope of the present invention is not limited thereto. Detailed descriptions of known configurations and functions that obscure the subject matter of the present invention will be omitted.

  FIG. 1 is a perspective view showing a general urinal, and FIG. 2 is an incision perspective view showing an internal structure of a backflow prevention urinal using an open / close ball according to a preferred embodiment of the present invention.

  As shown in the drawing, the present invention is a urinal composed of a urinal receptacle 100 and a drainage port 200. The drainage port 200 has technical features, and the drainage port 200 is largely divided into a housing 220, a main body 240, and an open / close ball. 260.

  First, as shown in FIG. 2, the housing 220 is provided at the lower portion of the urine receiver 100 and is connected to an underground sewer pipe (not shown) through which urine and washing water are discharged. The housing 220 is generally cylindrical, and the main body 240 and the open / close ball 260 are housed and mounted therein, and can be made of a material such as resin.

  A plurality of holes are formed on the upper surface of the housing 220 so that urine can pass therethrough.

  Next, the main body 240 is formed in the housing 220 to discharge urine and mechanically block back odors. The main body 240 mainly includes an inflow portion 242, a passage portion 244, an inclined portion. 246 and a discharge unit 248.

  The inflow portion 242 has a shape that is folded down on the upper surface of the housing 220, and the urine is directly introduced to guide the urine downward.

  Since the inflow portion 242 may have various shapes, it may have a cylindrical groove shape, may have a through-hole shape, and may have a conical groove shape that becomes thinner toward the lower side. It can also be. Moreover, as shown in FIG. 2, it can also have a shape like a substantially spiral flow path.

  The passage portion 244 is formed to communicate with the lower portion of the inflow portion 242, and is a circular hole that is penetrated, and has a shape that penetrates horizontally. Therefore, the urine that has flowed into the inflow portion 242 reaches the bottom of the inflow portion 242 and can flow out horizontally through the passage portion 244.

  Of course, the vertical cross section of the passage portion 244 may be formed vertically and may have a shape inclined at a certain angle.

  Further, an elastic packing (not shown) can be attached to the edge of the passage portion 244. This is to improve the sealing effect so that the opening and closing ball 260, which will be described later, is closed when closed. Usually, soft rubber or the like can be used for the packing.

  Here, the position of the passage portion 244 may be located approximately in the center of the main body 240 and communicated with an inclined portion 246 described later.

  The inclined portion 246 is a space that is inclined with a bottom having a curved surface, and an opening / closing ball 260 described later is accommodated therein.

  In other words, the inclined portion 246 can be inclined upward in a planar form from one side of the passage portion 244, but preferably has an inverted conical shape or a hemispherical shape so as to have a curved shape. It is preferable that the open / close ball 260 accommodated therein is swayed by an external force and can be restored to the center by its own weight at any position.

  Therefore, as described above, the passage portion 244 is located at the center of the housing 220, the inclined portion 246 is formed adjacent to the passage portion 244, and the lowest point of the inclined portion 246 and the passage portion 244 are By communicating, when the open / close ball 260 is restored, the passage portion 244 can be accurately blocked and closed.

  On the other hand, the discharge portion 248 is formed at the bottom of the inclined portion 246 and has a hole shape penetrating vertically, so that the urine passing through the passage portion 244 is discharged downward when reaching the inclined portion 246. So that

  The discharge part 248 may have various shapes such as a circle and a quadrangle, but has a size that allows the opening / closing ball 260 to move on the inclined part 246 without being detached.

  Next, since the open / close ball 260 has a spherical ball shape, the open / close ball 260 is accommodated in the inclined portion 246 and can be blocked while being lowered by its own weight and restored to the passage portion 244. It is. Further, it can have a weight that can be pressurized by the pressure of the backflowing gas and can be brought into close contact with the passage portion 244. As an example, a solid sphere of a light material or a hollow sphere having an empty interior. Etc. are appropriate. A hollow sphere such as a solid sphere or table tennis ball made of a material such as resin can be used.

  Of course, the open / close ball 260 is larger than the diameter of the passage portion 244 and larger than the discharge portion 248.

  In addition, a separate cap 300 may be further provided at the lower portion of the housing 220 in the present invention in order to double block the bad odor that flows back and improve the backflow prevention effect.

  The cap 300 may have a plug-like shape, and may be connected to a lower end of the discharge unit 248 to open and close the discharge unit 248.

  The cap 300 may have a shape corresponding to the cross-sectional shape of the discharge part 248 and is hinged to one side of the discharge part 248. Therefore, it can be opened and closed by an external force.

  A weight 320 having a constant weight as shown is attached to one side of the cap 300. The weight 320 is relatively heavier than the cap 300.

  Therefore, the cap 300 rises around the hinge connection due to the weight of the weight 320 and closes the discharge portion 248. If the urine reaches the cap 300, the cap 300 is opened by the weight of the urine.

  FIG. 3 is an incision perspective view showing the internal structure of a backflow prevention urinal using an open / close ball according to another embodiment of the present invention.

  Referring to FIG. 3 as another embodiment of the present invention, the discharge portion 248 may further include a through bag-like trap 400 instead of the cap 300.

  The trap 400 may be in the form of a bag that is coupled to the lower end of the discharge part 248 and penetrated, and the material may be thin vinyl or preferably latex.

  Latex is used as raw material for raw rubber and is used in various applications. In the invention, it has a bag shape with a thickness of about 0.1 mm, and is opened by the pressure of urine falling from above, allowing urine to pass through. After all the urine has passed, it will adhere to each other due to the water remaining on the surface. Therefore, the backflowing gas cannot pass through the trap 400.

  Hereinafter, the operating state of the present invention will be briefly described with reference to FIGS.

  FIG. 4 is a cross-sectional view showing a state in which the open / close ball of the present invention is operated to block a bad odor backflow.

  Referring to FIG. 2, when the user urinates, the urine flows into the inflow portion 242 and reaches the lower portion, and the opening / closing ball 260 that has blocked the passage portion 244 by the weight and pressure of the urine is removed. By pushing, the passage portion 244 is opened to pass through.

  The urine that has passed through the passage portion 244 flows to the inclined portion 246 and is discharged downward through the discharge portion 248. At this time, the open / close ball 260 can be lifted by urine partially remaining in the inclined portion 246.

  The urine discharged by the discharge unit 248 is accumulated in the cap 300 that has closed the discharge unit 248. When the weight of the urine exceeds the weight of the weight 320 at a certain moment, the cap 300 is moved to the seesaw. Open downward as shown. Therefore, urine is continuously discharged into the sewer pipe.

  Referring to FIG. 4, the open / close ball 260 is normally positioned at the lowest point of the inclined portion 246 by its own weight and blocks the passage portion 244. If the backflowing gas flows into the inclined portion 246 through the discharge portion 248, the open / close ball 260 is pressurized by the pressure of the gas, and the open / close ball 260 is further brought into close contact with the passage portion 244 to form a gas. Close the inflow of water.

  Also in the case of the cap 300, since the closed state is normally maintained by the weight 320, the backflowing gas is primarily blocked so that it does not flow into the inclined portion 246 through the discharge portion 248. However, since the gas partially leaked and backflowed to the inclined portion 246 is secondarily blocked by the open / close ball 260, it is possible to prevent the backflow of a certain foul odor. The case of the trap 400 is as described above.

  Further, as a preferred embodiment of the present invention, a control unit is further included.

  When the sensor device senses the user and recognizes the number of urine, the control unit controls the cleaning ball to be washed with water according to the number of urine.

  On the other hand, as another embodiment, the control unit can control the cleaning ball to be cleaned with water at regular intervals.

  With the configuration of the control unit as described above, the cleaning ball is always maintained in a clean state, and the operation state of the cleaning ball is maintained uniformly.

  The control unit cumulatively senses the number of times the user uses the urinal and notifies the user of the cartridge replacement time. Through this, the control unit notifies the user even if the user does not check the cartridge replacement time at regular intervals, so that the cartridge replacement time is not missed.

  Although the present invention has been described with reference to the preferred embodiments of the present invention, those having ordinary knowledge in the pertinent technical field should not depart from the spirit and scope of the present invention as defined in the following claims. It should be understood that the present invention can be modified and changed in various ways.
