BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet seat automatic paper feeder that can automatically cut a paper from a paper roll by sitting down.

[Prior art]

Thorough maintenance of sewers in recent years has promoted the spread of flush toilets that purify toilet excrement in septic tanks and discharge it to the sewer.The development of construction materials and the construction technology of residential houses is a new colorful material for toilets. Using, the old dirty image is renewed, and it has a feeling of cleanliness. On the other hand, based on the rapid economic growth, the restaurant industry such as restaurants and restaurants, the service industry in which an unspecified number of people enter and leave, such as hotels and wedding halls, have been disrupted. Is increasing with the improvement of. The restrooms of restaurants, hotels, etc. where an unspecified number of people come and go have changed from conventional batch type flush toilets to flush flush toilets in terms of hygiene and cleanliness. These flush toilets are overwhelmingly Western-style with a seat on a toilet seat that can withstand continuous and long-term use. An unspecified number of people who use the toilet seat of a Western-style toilet in such restaurants and hotels will also use it. Therefore, depending on the person who uses it, it may be unclean, and in particular, infection of a disease is considered. Therefore, recently, in order to sterilize and disinfect the top of the toilet seat, a toilet seat disinfecting cleaner in which a chemical solution is soaked in paper that wipes cleanly the top of the toilet seat has been developed and is generally commercially available. However, this toilet seat disinfecting cleaner uses sturdy paper because it cleans the toilet seat cleanly, and if it is thrown into the toilet after use, it may clog the toilet, etc., so it must be disposed of separately. It takes time and effort. The toilet seat of this Western-style toilet is usually made of hard plastic. Therefore, sitting directly on this hard plastic toilet seat is cold and difficult to use in the winter. In particular, after the toilet seat disinfectant cleaner has been wiped cleanly, the chemical solution contained in the toilet seat disinfectant cleaner adheres to the surface of the toilet seat, making it extra cold and difficult to use. Therefore, in order to prevent unsanitary conditions caused by direct skin contact with the toilet seat and to soften the coldness even when sitting on the toilet seat in winter, recently a toilet seat paper is laid on this toilet seat. The method of using it has come to be considered. This toilet seat cover uses a special toilet seat that has been remodeled so that the roll can be continuously supplied by winding the toilet seat cover on a roll.

[Problems to be solved by the device]

However, in the case of a toilet bowl configured to be wound around a roll and continuously supplied with such a conventional toilet seat sheet, when the toilet is newly constructed or the toilet bowl is reconstructed, the toilet seat sheet is used. It can be used by adopting a special toilet that can set paper, but for existing toilets,
It has a problem that it cannot be used at all. In addition, in the conventional toilet bowl that is configured to be wound around a roll so that it can be continuously supplied, the existing toilet bowl must be removed and replaced with a modified toilet bowl. Have Further, in the supply of such toilet seat cover sheet for a conventional toilet bowl, after the toilet bowl is used, the used toilet seat cover sheet is torn by hand from the roll and thrown into the toilet bowl. For this reason, there is a problem in that it is very troublesome to use the toilet seat paper. The present invention has been made in view of the above problems of the prior art, and its purpose is to open and close the lid of the toilet bowl without touching the cover sheet on the toilet seat. A sheet for toilet seat that can be automatically sent out as needed and placed on the toilet seat, and by automatically sitting down on the toilet seat of the toilet bowl, the sheet can be cut from the sheet roll. It is intended to provide an automatic feeder.

[Means for Solving the Problems]

In order to achieve the above object, the toilet seat automatic sheet feeder according to the present invention is rotated by opening a pawl attached to a lid of a toilet bowl and a pawl rotatably attached to the toilet bowl by engaging the pawl with the lid. The ratchet, a drive gear that rotates by receiving the rotation of the ratchet, a pair of rollers that press against each other and rotate to feed the toilet seat sheet onto the toilet seat, and are attached to one of the pair of rollers. A gear that meshes with the drive gear, a fixed blade portion that stands upright on the upper end of the main body of the toilet, and a rear portion of the toilet seat are configured to be movable up and down, and the rear portion of the toilet seat that meshes with the fixed blade portion and the rear portion of the toilet seat is vertically moved. It is configured by a moving blade portion that cuts the toilet seat cover sheet laid on the top. Then, protrusions are provided at equal intervals on both ends of one of the pair of rollers. Further, a braking member is provided on one of the pair of rollers. In addition, the lid portion of the toilet bowl is provided with a paper feed release lever that releases the engagement between the pawl and the ratchet. The paper feed release lever is for opening and closing the lid and opening and closing the toilet seat to press the pawl to release the engagement with the ratchet.

[Action]

Insert one end of the toilet seat paper wrapped around a roll between a pair of rollers that are pressed against each other, pull out the toilet seat paper a little from between the pair of rollers, and raise the blade to the upper end of the toilet body. The edge of the sheet of paper is slightly pulled out through the gap between the base and the moving blade provided on the rear of the toilet seat, and the lid of the toilet is closed. Since the toilet is used, when the lid is opened, the ratchet with which the claw attached to the lid is engaged is pushed and rotated. Then, the drive gear is rotated by the rotation of the ratchet, and the gear is rotated by the rotation of the drive gear.
The rotation of this gear causes one of the pair of rollers to rotate, and the toilet seat sheet sandwiched between the two rollers is delivered onto the toilet seat. By appropriately adjusting the number of gears of the drive gear and the number of gears of the drive gear, the toilet seat cover can be placed on the toilet seat by one opening movement of the lid portion of the toilet bowl. Then, when the person sits down on the toilet seat, the rear portion of the toilet seat, which is constantly lifted, is pushed down by a spring or the like, and the movable blade portion and the fixed blade portion sandwich the toilet seat sheet and cut out the sheet for toilet seat. When the lid of the toilet bowl is closed, there is no engagement between the claw and the ratchet, and it runs idle. For this reason, the ratchet does not rotate and is not fed in the retracted direction, which is the reverse of the delivery of the toilet seat paper sandwiched between the two rollers. Rotation of the ratchet due to movement of the pawl when the lid of the toilet is closed is prevented by a braking member provided on one of the pair of rollers. Further, when it is inconvenient that the toilet seat cover sheet is delivered onto the toilet seat by one opening operation of the lid portion of the toilet bowl, it is possible to release the engagement between the pawl and the ratchet by pressing the paper feed release lever. Even if the lid of the toilet bowl is opened and closed, it is possible to stop sending the toilet seat cover onto the toilet seat. Since this paper feed release lever is configured to operate by opening and closing the lid and opening and closing the toilet seat, when the toilet seat is opened and closed when the lid is opened and closed, the toilet seat presses the paper feed release lever, The release lever pushes the pawl to release the engagement between the pawl and the ratchet.
