Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention provides a liquid splash prevention device,
In particular, the present invention relates to a device for preventing, attenuating or suppressing the splashing effect when a solid or liquid material collides with a liquid surface.

[0002] During the collision, the kinetic energy of the liquid or solid material colliding with the surface is released and transferred or distributed to the collided liquid, so that the liquid reaches an inherent momentum and separates from the liquid surface. The problem of splashing varies with the size of the solid relative to the area of the liquid surface being impacted, which area is related to the size of the container or tube containing the liquid. In the case of a container, if the solid or liquid material has sufficient mass or dimensions and falls a sufficient distance before impacting the liquid surface, the impact may result in water being thrown up and over the edge of the container.

0003

BACKGROUND OF THE INVENTION GB 2077791 discloses a liquid anti-splash device having a float extending over a large portion of the liquid surface and anchored or held in place. This float is positioned to collide with the solids in the container and is intended to prevent the solids from directly colliding with the liquid surface. The anti-splash device described in this patent is a one-piece, generally rigid disc-shaped float.

0004

However, with such conventional devices, there is a risk that the solid may not be easily separated from the float after a collision. There is also the disadvantage that splashing cannot be sufficiently prevented. One of the objects of the invention is therefore that after the first impact with the liquid surface the general path of the solid or liquid material is not obstructed, that it can be adjusted to suit containers of different dimensions, and that after the impact the device It is an object of the present invention to complete a liquid splash prevention device that allows solids to be easily detached from a surface in an improved manner. Another object of the invention is to provide a device that eliminates or at least reduces impact noise caused by direct impact of a liquid or solid with a liquid surface. Another object of the invention is to prevent or at least reduce odors emanating from the liquid into the surrounding air. Yet another object of the invention is to provide a device that can prevent liquids or solids from floating on the surface of the water and being exposed within the container.

[0005] The present invention particularly relates to the prevention of splashing in the container or bowl of a sanitary toilet bowl, particularly a flush toilet in which a water sealing trap is formed in a U-shaped water pipe formed integrally with the base of the container and communicating with a sewer pipe. However, it is not limited to these uses. A water seal or trap is an airtight part that keeps the container and inner walls of the pipe clean, forms an initial mass of water that dissolves and washes away the waste that has settled in the bowl, and also prevents toxic gases from rising inside the pipe and entering the bowl. It is essential for the sanitary purpose of forming. The water seal is linked to water discharge equipment that pours water from the edge of the bowl in order to dissolve the contents of the bowl and flush it into the sewer.Each time, the first flow of the water discharge operation releases water from the beginning of the U-shaped pipe. A new water seal is formed by excess water that collects in the U-tube after the contents have been flushed into the sewer pipe communicating with it and then into the sewer pipe communicating with the flush toilet insulation. Water sealing is practically indispensable as mentioned above, but for example, feces that descend or settle in the bowl,
An unfortunate side effect is splashing due to the impact of liquids or solids such as urine or other substances. The splash effect depends on the nature of the impact, as generally stated above;
This can also result in unpleasant and unhygienic contact of the user with waste water.

SUMMARY OF THE INVENTION The present invention provides a liquid splash prevention device having a plurality of elongated floats projecting from a bearing, said bearing including attachment means for attachment to an inner wall constituting a container or tube. In the apparatus, the elongated float is arranged to extend substantially over the entire surface of the liquid in the container or tube, generally parallel to a direction generally transverse to the flow path of the liquid along the tube or out of the container. , said elongated float collides with solid or liquid objects entering the container or moving along the tube, and the collision is prevented by preventing those solids or liquid objects from colliding with a major part of the liquid surface. A prevention device is provided which is characterized in that it prevents the splashing effect. Embodiments of the invention have a float that is not fixed at one end, so it does not impede the flow of liquids and solids when installed in a flush toilet.

In a preferred embodiment of the invention, the spacing between each elongated float and adjacent floats is approximately 1 to 5 meters.
It is m. The elongated floats can each be hinged to a bearing so that upon impact with a solid or liquid object, they bend downward and sink into the liquid. Alternatively or in addition to this hinged attachment, the elongated float can be formed of a material that is sufficiently flexible to bend downward under the weight of liquid or solid matter. This bend helps to reduce or eliminate the collision noise that occurs between the solid or liquid and the liquid surface. Biasing means may be provided between the elongated float and the bearing to assist in restoring the bent float to its pre-bent condition. Preferably, the elongated float has a smooth surface to aid in the removal of liquids and solids. The elongated float itself may be hollow in shape or may have a D-shaped cross-section and be provided with a flat upper part and a rounded lower part. The attachment means has a surface that can be adhered to the inner wall and can be firmly connected to the inner wall. It is also possible for the attachment means to have hooks formed on the surface of the bearing and to be connected to a corresponding coupling part fixed to the inner wall of the container or tube. The elongated float and bearing can be integrally molded from a plastic material such as polypropylene.

[0008]

Effect: The elongated float collides with solid or liquid objects entering the container or moving along the tube, by preventing those solids or liquid objects from colliding with a major part of the liquid surface. Prevents splashing effect.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to a case where it is installed in a sanitary flush toilet bowl, which is a general embodiment shown in FIGS. 1 and 2. The illustrated device has eight or nine hollow floats 1 separated from adjacent floats by gaps 2 of 1 to 5 mm. Said elongated floats 1 are each hingedly attached to a bearing 3 via a hinge 4. The elongated float 1 and the bearing 3 can also be molded in one piece from a plastic material such as polypropylene. In this embodiment, the hinge 4 can also be formed by a thin strip of plastic material that can provide a hinge movement between the elongated float 1 and the bearing 3 without breaking. A plastic hinge 4 formed in this manner can maintain the integrity of the device over long periods of time.

The bearing 3 can be attached to the inner wall 5 of the flush toilet by gluing or other suitable attachment methods. It is also conceivable for the attachment means to be formed with hooks (not shown) for coupling with corresponding coupling parts of the inner wall 5 of the flush toilet. The device is attached to the inner wall of the lower part of the vertical branch 6 of the U-trap or to the inner wall 5 of the flush toilet at the neck 8 of the bowl 7 of the flush toilet. A column of water 9 (standing water) with an exposed top surface 10 is located inside the U-trap to form a water seal and the bowl is closed until conventional drainage equipment discharges the waste through the U-trap and into the connecting sewer. 7. Retains the waste that flows into the tank.

The elongated float 1 is dimensioned to extend over substantially the entire upper exposed surface of the water column 9. It is ideal if there is no exposed part on the upper exposed surface 10 other than the gap formed between the elongated floats 1 described above.

The liquid or solid matter falling into the ball 7 falls onto the elongated float 1 as shown in FIGS. 3 and 4. In FIG. 3, the elongated float is made of a material that inherently floats on water and is formed into a hollow shape. FIG. 4 shows another shape of an elongated float, with a D-shaped cross section,
The flat upper part allows the float to be impinged by solids or liquids, while the lower part of the elongated float is bent downwards and has a rounded shape to minimize water resistance when submerged in standing water 9. The flat surface of the float 1 provides a better quality and wider landing surface for liquids and solids.

The elongated float 1 is sufficiently flexible to be bent as shown in FIG. The impact of a collision is absorbed by the elongated float without splashing water outside the flush toilet. The elongated float is made of a light and soft material (polyethylene, natural rubber, silicone rubber, polyurethane, etc.) and collisions are relatively quiet.

After the elongated float 1 is bent as shown in FIG. 5 by the weight of the liquid or solid material, the material naturally slides off the surface of the float 1 and falls into the water 9. The surface of the float 1 can also be made very slippery to help the material slide off the float 1. To obtain a slippery surface, the surface can be coated with a thick layer of polyethylene, PVC or similar coating. Thereafter, the float naturally returns to its original position, as shown in FIGS. 6 and 7. Float 1 for flushing water from the flush toilet
aids in the removal of substances from surfaces.

FIG. 8 shows the biasing means provided between the support 4 and the bracket 11 to which the elongated float 1 is mounted. This biasing means may be in the form of a resilient or elastic rubber material and assists in returning the float to its original, unbent condition.

As shown in FIG. 9, an embodiment of the present invention allows the elongated float 1 to be made relatively long in advance so that it can be cut to fit the flush toilet in which the device is installed.

Embodiments of the invention can be constructed in such a way that the elongated float 1 can be removed from the bearing if necessary, so that the float can be replaced.

[0018]

[Effects] As described above, the present invention effectively prevents liquid from splashing in the flush toilet bowl, making it possible to use the flush toilet bowl in a sanitary manner.
