Description

Sanitary Toilet Cover {Method and Apparatus of Providing Sanitary Toilet Cover}

The present invention relates to the structure and operation method of a toilet lid and toilet seat to prevent the spread of aerosols generated when flushing a toilet and to facilitate opening and closing of the toilet lid and toilet seat.

The toilet that modern people use every day wherever they live is made up of pottery, a lid, and a seat. Figure 1 shows the structure of a commonly used toilet. After using the toilet, the lid 103 is closed and the flushing handle 101 is pressed, so that the water contained in the water tank 102 remains in the pottery 105. It works by washing away the water.

In the Channel A “Doctor Zhivago” program broadcast on November 27, 2017, it was broadcast that when flushing the toilet, aerosols containing urine are spread and contaminate toothbrushes and towels provided in the bathroom, Korea Safety Newspaper 2009 The July 15 article, “Public Toilets Are a Kingdom of Germs,” cited UN World Health Data and stated that 2 million people die annually worldwide due to poorly hygienic toilets, and that most of the deaths are children under the age of 5 with weak immune systems. In particular, it is pointed out that 80% of female uterine cancer is caused by secondary infection through toilets, etc., indicating the seriousness of the problem. In addition, a paper (Virus transmission from urinals, Ji-Xiang Wang) published in the journal Physics of Fluid on June 16, 2020 showed that, through computer simulation, COVID-19 aerosols spread more than 1 meter when flushing the toilet, causing the virus to spread. It has been shown that transmission is promoted.

The toilet lid 103 of restrooms, especially public restrooms, is not only in an unsanitary state due to neglect of management, but also the act of opening and closing the toilet lid 103 by hand causes discomfort, so most users do not use the toilet lid 103. Water is being flushed without being closed, and aerosol diffusion is being neglected due to this. Therefore, in order to prevent the spread of aerosols generated in the toilet and prevent indirect infections that may occur when touching the toilet lid 103 or seat 104 with hands, a more hygienic toilet lid 103 and seat 104 ) needs to be provided.

It is recommended to close the lid 103 and drain the water, but since the existing lid 103 is structured to simply cover the sheet 104, an empty space exists between the lid 103 and the sheet 104. Therefore, when the lid 103 is closed and the water is flushed, aerosols may be adsorbed on the seat 104, resulting in contaminants on the thighs of the next user when seated. Additionally, in order to close the lid 103 and drain the water, the user must touch the contaminated lid 103 with their hands, which increases the possibility of indirectly being infected with bacteria or viruses. In particular, in the case of a toilet shared by men and women, the possibility of indirect infection may increase during the process of opening and closing the lid 103 and the seat 104 individually. Therefore, it is desirable to provide a method of opening and closing the lid 103 and the sheet 104 in a hygienic and convenient manner.
