Description

Flush toilet for lower body washing and seat disinfection

The invention relates to an ice toilet, in particular to a toilet for post-cleaning and seat disinfection. Background technique

With the development of society and the continuous improvement of people's living standards, the cleaning device and the toilet seat cleaning and disinfecting device as the body cleaner are increasingly accepted and loved by the general public. They are loved because they provide people with a healthy, hygienic and disease-preventing lifestyle.

The post-cleaning device allows people to wipe the body without using paper afterwards. The existing 3⁄4 device includes a rotary valve composed of a valve core, a valve body and a front and rear valve cover, a pump, a water tank, a valve control device and a nozzle device, wherein the cleaning function of the nozzle device is to rush the anus or rush through the rotary valve The spray body supplies water, the water entering the spray body reaches the nozzle at the front end, and then a set of water flows through a set of fine holes of the spray head for cleaning the anus of the human body. In recent years, some famous brands of sanitary ware manufacturers in some countries have introduced some products, claiming that their sprays can be inclined relative to the anus. We fully understand why these companies are taking such measures. This is because the nozzles of many products are often designed to be directly below the anus of the human body. When the nozzle of the jet body sprays the water up to flush the human anus, the stool adhered to the anus is washed down, and falls vertically on the plane around the nozzle orifice, and many users may suddenly or urgently The stimulation of the anus during rinsing causes a chain reaction of the large intestine, and the stool can not be immediately removed from the body and fall on the nozzle, so that the nozzle or the spray body is contaminated. The design of the oblique jet of the spray body relative to the anus does not really solve the pollution problem described above, and causes a large area of water to be sputtered, which causes inconvenience to the user.

The toilet seat cleaning and disinfecting device is mainly used to ensure the use of public toilets in public places, such as town streets, public toilets in hutongs, public toilets used by government agencies and institutions, especially the toilets of railways, aviation or long-distance passenger hubs with relatively concentrated people. Circle of hygiene. The device mainly comprises a water supply tank installed at the rear of the toilet, a water washing mechanism, a drainage mechanism, a seat rotating mechanism, a hot air drying mechanism, an ultraviolet light sterilization mechanism and an automatic control mechanism. After the user is in the toilet, the seat can be rotated into the disinfection chamber of the water supply tank under the control of the automatic control mechanism, and the water liquid washing mechanism, the hot air drying mechanism and the ultraviolet light sterilization mechanism are sequentially driven to perform the seat ring. Wash, dry, and sterilize to ensure the seat is safe and safe to use. In the prior art device, the drain mechanism is a water tank from which the liquid flushing mechanism is inserted, and is connected to the flushing water supply port of the toilet, which not only affects the water storage amount of the water tank but is also very troublesome in manufacturing. For details of the above related technologies, including the invention patent of the applicant's application number 99113981.X titled "post-cleaning device" and the application number submitted on February 22, 2005, which was filed on August 16, 1998.

For the detailed structure and usage principle of the rotary valve 6 and the valve control device, please refer to the Chinese invention patent granted to Pan Dingguo N0.99113981.X.

The two injection devices 7, 8 and or the fan-shaped irrigation tube 9 are mounted on the rear valve cover 64 of the rotary valve 6 and are respectively in communication with the three water outlets thereon to form a controllable water supply. The nozzle devices 7, 8 are respectively an irrigated and fluted nozzle device, and the structures of other parts are basically the same except that the nozzles can be designed into different internal and external geometric shapes or structures according to the rinsing requirements. . Therefore, in order to reduce the space, the sinus nozzle device 7 will be described as an example herein. The utility model comprises an outer tube body 71, an inner tube body 72, a spring 73, a sleeve 74, a nozzle 75 and a sealing member 76. The outer tube body 71 is a tube body having a constricted neck portion 711 at the front and is external. The tubular body has an annular convex wall 712 projecting radially inwardly at one end and a mounting seat 713 projecting radially outward at the other end.

The collar 3033 is fastened on a shaft portion of the shaft pin 3031 adjacent to the position of the driven pulley 3042. The spring 3032 is fitted on the shaft portion of the shaft and the two ends thereof are located on the collar 3033 and the inner wall of the seat support. The gap is between the inner shoulder 2046 and the cover. In the case where the side plate portion 205 and the side wall 23 of the seat boss portion are relatively close, in order to better accommodate the spring 3032, an enlarged bore 3048 can be provided on one side of the driven pulley 3042, and the inner shoulder 2046 of the cover spring 3032 can be extended into the enlarged bore 3048 of the pulley for ease of handling and maintenance.

Before introducing the hydrophobic water rinsing mechanism 50, as an additional part of the seat sterilizing device, a plurality of mouths may be placed in the inner cavity near the ring hole in the lower portion of the seat 2, A ware nozzle 25 of a corresponding hole of the bottom or bottom plate facing the inner wall of the toilet.

Referring to Figures 1, 2 and 18 to 19, the hydrophobic flushing mechanism 50 includes a plurality of water jets 501, at least one clean water pump 502, and a fresh water dispenser 503 and a distributor drive mechanism 504. The water sprinklers 501 are disposed on the front surface of the clean water tank and face the sterilization chamber. Preferably, they are arranged in the shape of the race 2 so that the water spray head 501 can be directly sprayed against the upper ring of the race; the clean water pump 502 is conventional. The pump, its inlet is connected to the clean water tank 202 through a pipe and placed in the pump chamber 203; the clean water distributor 503 is a three-way rotary valve having an inlet and two outlets, which are also connected to the water-clearing dish through the tube 502, the two outlets are respectively connected with the water spray head 501 and the sanitary nozzle 25; the distributor transmission mechanism 504 is capable of opening and closing the driving water distributor 503 and selectively distributing water to the outlet.

Referring again to Figures 17 through 18, the clean water distributor 503 is structurally comprised primarily of a three-way valve seat 5031, a spool, and a rotating shaft 5033 for rotating the core. It is mounted at another position above the motor reduction box 302 and is opposed to the top and bottom.
