Description

Hand washing device having a lifting type nozzle {HAND WASHING DEVICE USING ELEVATOR TYPE NOZZLE}

The present invention relates to a hand washing device, and more particularly, by moving a water spray nozzle for hand washing up and down like an elevator, the weight and volume of the device can be reduced, and the water spray nozzle for hand washing can be easily washed. It is about a one hand washing device.

In 2021, the world is now experiencing economic/social difficulties due to the corona virus, and many countries are experiencing economic downturn due to the virus.

The most frightening thing about COVID-19 is the rapid transmission rate through droplets, but it is very difficult to track confirmed cases, and the number of confirmed cases increases exponentially due to the nth infection. So far, the only preventive measures are strict personal hygiene management such as physical social distancing, wearing a mask, and hand washing to reduce contact with an unspecified majority and reduce the probability of transmission to others due to unknown infection.

The easiest and most effective way to block the spread of infectious diseases is ‘hand washing’. It is known that proper hand washing is effective in reducing most infectious diseases such as influenza, cholera, bacillary dysentery, and epidemic conjunctivitis. The U.S. Centers for Disease Control and Prevention (CDC) recommends handwashing as the easiest and most effective way to prevent infectious diseases, even calling it a “do-it-youself vaccine.”

However, it was found that not only the general public in Korea, but also workers in medical institutions did not thoroughly wash their hands. Health authorities and medical institutions are conducting various campaigns to establish a 'handwashing culture' to prevent infectious diseases, but the rate of handwashing is still low.

For personal health, it is necessary to observe 'correct' hand washing in running water for at least 30 seconds, but very few people practice this.

The main cause is that most people do not know the 'correct' hand washing method itself, and very few people wash all parts of their hands (palms, backs of hands, between fingers, etc.) and nails with detergents such as soap for more than 30 seconds. Even people who frequently wash their hands are living a life no different from not washing their hands by not washing their hands 'properly'.

Despite the prevalence of infectious diseases such as COVID-19, the number of people who wash their hands with the correct handwashing method is very small, and there are cases where people are relieved to think that they have washed their hands even though they only use hand sanitizers that do not sterilize and clean properly compared to proper handwashing. many.

Korean Patent Registration No. 10-1730597 discloses a 'hand washing device' for automatically washing hands. This conventional hand washing device has technical significance in automating hand washing by simply spraying water on the hand, but the washing rate is lower than that of proper hand washing, and the device itself is contaminated due to wastewater generated after washing There was a problem with unsanitary management.

On the other hand, the conventional hand washing device also has a problem in that it is bulky and heavy. Various equipment for hand washing is required, and in particular, since a washing bucket, a water tank, and a waste water tank are essential, the size of the equipment increases and the weight increases. Here, in the case of a hand washing device in which wastewater is directly discharged without a wastewater tank, it can be installed only in a place where wastewater can be discharged, which causes problems such as inconvenience and odor.
