Abstract

A flush toilet used for post-stool cleaning and toilet seat disinfection, comprising a toilet, a toilet seat, a post-stool cleaning device, a toilet seat disinfection device, and a control circuit. The post-stool cleaning device includes a water supply valve, a cleaning valve, a pump, an anus cleaning device and a genital cleaning device. The toilet seat disinfection device includes a water supply tank, a toilet seat rotation mechanism, a water supply / drainage mechanism, an ultraviolet sterilization mechanism, and the like. The spray device for anus cleaning and genital cleaning consists of an outer tube body, an inner tube body, a nozzle, and a casing. An opening is provided on the end surface of the casing, and the narrow diameter portion of the outer tube body can be passed through. Since the inner wall forms a ring-shaped gap that connects to the opening of the casing together with the outer wall of the narrow diameter portion, self-cleaning can be realized simultaneously with anal cleaning and genital cleaning. In other words, the combination application of the spraying device is realized by cleaning the dirt that has fallen on the nozzle. At the same time, since the toilet seat disinfection device of the present invention has been improved in terms of structure, it can be combined with post-stool cleaning, toilet seat cleaning, drying, and UV sterilization to ensure hygiene of toilet seats used in public places.

Description

  The present invention relates to a type of flush toilet, and more particularly to a flush toilet used for post-stool cleaning and toilet seat disinfection.

  With the development of society and the improvement of people's standard of living, the post-stool cleaning device and toilet bowl cleaning / disinfecting device as body cleaning devices provided people with a healthy and hygienic lifestyle that can prevent diseases. More and more people are recognized and liked.

  If you use a post-stool cleaning device, you can avoid using toilet paper. In the prior art, the device comprises a valve core, a cleaning valve composed of a valve body and front and rear valve caps, a pump, a water tank, a valve control device and a nozzle device. Among them, the cleaning function of the nozzle device provides water to the spray body for anal or genital cleaning with a cleaning valve, and after the water that has entered the spray body has arrived at the nozzle at the tip, the water flow is sprayed from a minute hole in the nozzle In addition, it is possible to clean the anus and the like of the human body. In recent years, prominent sanitary manufacturers in several countries have launched new products, appealing that the injector can be injected obliquely to the anus. The reasons why these companies take such measures are well understood. Because many products have nozzles installed directly under the human anus, the stool attached to the anus is washed away at the same time as the nozzle of the sprayer sprays a stream of water on the body and cleans the anus of the human body. It falls perpendicular to the surrounding plane. In addition, many customers urge the anus when urinating the stool or wash it, resulting in a chain reaction of the large intestine, and the stool is discharged uncontrollably and falls to the nozzle, causing contamination of the nozzle or ejector. Because. Such a design in which the ejector ejects obliquely with respect to the anus cannot solve the above-mentioned contamination problem in earnest, and the water is scattered over a large area, which is inconvenient for the customer.

The cleaning valve 6 is a four-port valve, and the front and rear valve caps 63 and 64 each have one water supply port and three water outlets.When the cleaning valve is operated, the groove and the valve body are made in the valve core. By connecting a certain water supply and outlet, water is distributed and drained from one of the outlets, and used for anal cleaning, genital cleaning and toilet seat fan cleaning. This distribution is selectively performed by the valve control device. The valve control device includes a motor 66, a speed reducer 67, and a valve control unit 68. Among these, the motor 66 employs a low-pressure AC motor. For example, a 24V AC synchronous motor or the like. The reducer 67 employs a gear box, and its input shaft is connected to the output shaft of the motor 66. The valve control unit 68 includes a ring-shaped light shielding plate, a photoelectric tube plate component, and a control circuit board. Among these, the ring-shaped light shielding plate described above is four radial projecting claws partitioned at a fixed angle. The cross-section is groove-shaped and the width of the groove is the same as or slightly wider than the overhanging claw. It starts to drain from the water outlet that covers the overhanging nails. Please refer to the Chinese Invention Patent No.99113981.X awarded to a certain country for the detailed structure and use mechanism of the washing valve 6 and valve control device.

  The two injection devices 7 and 8 and / or the fan-shaped cleaning pipe 9 are provided in the rear valve cap 64 of the cleaning valve 6 and are connected to three water outlets at the upper part thereof to realize controllable water supply. Nozzle devices 7 and 8 are anal and genital cleaning nozzle devices, respectively, and the nozzle can be designed as an anal or genital cleaning nozzle with various internal / external geometric shapes or structures depending on the requirement of cleaning. The structure is almost the same. Therefore, in order to shorten the length of the sentence, in the text, the anal cleaning nozzle device 7 will be described as an example.
