Sensing-Type Lavatory Seat Structure with Covering Film

Abstract

A sensing-type lavatory seat structure with covering film includes a covering film output portion and a covering film collecting portion, a rolling motor and a pivot motor accommodated in a body portion thereof, and a U-shaped seat, through two ends thereof, connected to the covering film output portion and the covering film collecting portion. When the user approaches, a sensing unit senses the situation, controls the pivot motor to lower down the seat and controls the rolling motor to replace the covering film. Then, after the user leaves, the sensing unit once again senses the variation, and controls the pivot motor to lift up the seat to wait for the next time usage.

Description

FIELD OF THE INVENTION[0001]The present invention is related to a sensing-type lavatory seat structure with covering film, and more particularly to a lavatory seat structure which can automatically replace the covering film for the seat and also can lower down and lift up the seat corresponding to a detecting result from a sensing unit.BACKGROUND OF THE INVENTION[0002]Water closet is a very important invention in modern times, even more important than the gunpowder and the compass. Without water closet, people might not get free from the foul smell of excrement. It is a general opinion that water closet was invented by Sir John Harrington, who was a courtier of Queen Elizabeth, in 1596. Until 1778, Joseph Bramah improved the design of water closet and granted the patent. Right now, not only for flushing excrement, the water closet also should be provided with other functions, such as sanitation and comfort.[0003]Generally, when using a public lavatory, some people might just sit on ...

Benefits of technology

[0011]In the present invention, the main body is mounted on the base of the water closet, so that when the user approaches, the sensing unit detects the position of the user through the optical sensing unit and sends out signal to the pivot motor, and then, the pivot motor drives the pivot. When the seat lowers down, the pivot motor stops driving the pivot and sends out signal to the rolling motor, so that the rolling motor drives the collecting roller to roll up the covering film, so as to collect the old covering film into the collecting roller and replace a new covering film for the seat. Therefore, every user can have a brand-new covering film.

Problems solved by technology

Without water closet, people might not get free from the foul smell of excrement.

Therefore, for avoiding from being contaminated by the dirt or filth, some people might directly squat on the lavatory seat, which actually will worsen the situation and also make the later user more uncomfortable.

However, this method might consume the toilet paper, and actually, the wind pressure caused from the sitting action of the user might also blow the paper away, so that this obviously is very inconvenient.

But, this conventional structure is disadvantageous that if the former user splashes the filth or sewage onto the cushions, it might become, not only the topmost cushion, but all the
