Description

Pop-Up Open-Type SMA Water Saving Valve using One-Touch Forced Shape Memory Alloy

The present invention relates to a water-saving urinal valve using a shape memory alloy capable of forcibly opening one-touch.

In the existing method of washing urine with water, the U-shaped tube was used to prevent the backflow of the smell, but the smell of urine and urine accumulated in the U-shaped tube was bad. In particular, the sedimentary stones were precipitated in the drainage pipe over a long time, which prevented the smooth flow of water and caused the backflow phenomenon.

Below is a description of a waterless urinal developed by the US Falcon Company.

The upper part of the urinal may not be washed with water and may smell bad, but vice versa. A humid environment is good for germs to grow. Conventional urinals not only continue to use water, but because they do not have enough water pressure to wash the scales and bacteria, the bacteria continue to thrive in the scale.

Falcon Waterfree urinals do not use water, which keeps them dry, so bacteria do not grow well. According to an experimental report in Germany, the number of bacteria in the Falcon Waterfree urinals is only about one fifth of that of conventional urinal bacteria.

Dr. Gerba's report, Department of Environmental Microbiology, University of Arizona, also found that urine-washing urine can't remove bacteria. In addition to the large number of bacteria in the urinal itself, as soon as the water was washed, the bacteria spread around the toilet, there was a problem of a breeding ground for bacterial contamination.

SUMMARY OF THE INVENTION The present invention provides a urinal valve that is easy to manage while maintaining clean conditions without using water.

According to an aspect of the invention, the upper stopper is formed through holes to inject urine; External structures that collect urine; A valve stopper separated from the outer structure to discharge urine; A bias spring providing an elastic force to the valve cap to prevent backflow of odor or urine odor; A shape memory alloy spring that provides an elastic force to the valve cap so that the valve cap is opened by the temperature of the urine; And a water-saving urinal valve using a one-touch forcible openable shape memory alloy including a holding portion interposed between the outer structure and the valve cap so that the valve cap is opened by the user is provided.

Here, the holding portion is a push rod formed with a guide protrusion on the outer peripheral surface; A housing in which a guide groove is formed on an inner circumferential surface to guide the movement of the guide protrusion; Interposed between the pressing rod and the valve cap, the engaging piece is formed on the outer circumferential surface; And a locking groove formed adjacent to the guide groove on the inner circumferential surface of the housing so that the locking projection is caught in the lowering state of the locking piece.

At this time, the inclined surface is inclined toward the locking groove is formed between the guide groove and the locking groove, the inclined portion is formed in connection with the inclined surface so that the locking projection is moved to the locking groove at the end of the pressing rod.
