Water closet, with the advantage of its comfort and health, replaces pan gradually in public lavatory.Then the closet seat cushion causing because of certain user's improper use pollutes, and makes user and cleaning worker quite feel headache, and this has become the long-term urgent problem that solves expected of people.
Existing technical scheme mainly contains two kinds:
One, adopt toilet seat packing paper, have following shortcoming: 1. paper waste is seriously difficult to management and not environmental protection, 2. very thin cushion paper is difficult to deal with degree of depth pollution (such as there being urine on cushion);
Two, automatically clean the water closet of cushion, the patent that for example application number is CN201220657560, it is designed with electric installation, utilizes microwave to clean cushion; Also having some inventions is to use current or gases at high pressure etc. to rinse.These invent total shortcoming is complex structure, and cost is high.
The technology prejudice that prior art exists:
These technology prejudice circles have been lived people's innovative thinking, mainly contain two kinds:
Prejudice one: when cushion is cleaned, be all that cushion is fixed, and burnisher motion (brush for example moving back and forth is scrubbed cushion), or cleansing medium (for example fierce current or gases at high pressure) directly washes away cushion;
Prejudice two: public lavatory cushion be still designed so that with after can take in (modal is upwards to start).Cushion is taken in, and is originally in order to use in private residence, avoid man's urine pollute cushion and design, and in public lavatory, all have independently urinal for male, so this design is inessential.Moreover people not gladly touch the cushion of public lavatory water closet with hand.
Summary of the invention
The present invention is intended to overcome conventional art prejudice, looks for another way and does things creatively, and takes brand-new solution, when automated cleaning closet seat cushion, not by electric power also not by high pressure, do not need control chip, create a kind of durable, public lavatory water closet that effect is excellent simple in structure.
One, innovation thinking:
The rat-fuck thinking of the present invention is: make burnisher (for example brush) fix and cushion motion.For this reason, we select the ring-type flexible pipe of sealing to replace traditional hard cushion, can gassy or liquid in this flexible pipe, and this cushion can produce deformation laminating buttocks under human buttock's pressure, makes us feeling comfortable.
Use this hose loop of drive wheel to rotate around toilet.The kinetic energy transmission that the driving force system of this driving wheel started or depressed toilet lid by user.
Technical scheme based on this design is as accompanying drawing 1, should from clear cushion water closet mainly by: in be plugged with irony particle closed circular flexible pipe cushion (1), be pressed in the pinch roller (2), the Dirt-cleaning brush (4) that is used for removing spot on flexible pipe that drive hose loop to rotate around toilet on flexible pipe cushion, be used for drying blade water stain on flexible pipe (3), be arranged in toilet seat, be used for adsorbing flexible pipe build the magnet (5) of magnetic orbit, connect water-closet tank with jet water course by Dirt-cleaning brush (4) above spot pour the nozzle (6) in toilet; Form with toilet lid, toilet seat, water tank.
As accompanying drawing 3, gear is housed in toilet lid, the gear drive pinch roller that this of gear engagement is arranged in toilet seat rotates, thereby flexible pipe cushion is rotated around toilet.
Certainly, flexible pipe cushion also can adopt other modes to carry out transmission:
1. such as the mechanical energy by spring savings toilet lid, then discharge to pinch roller.2. use the mechanical energy of battery and generator savings toilet lid to re-use Motor Drive pinch roller.3. directly with electric power (motor), drive pinch roller.4. directly provide crank handle to allow user directly rotate pinch roller.Etc. include but not limited to above-mentioned various existing transmission scheme.
The emphasis must be appreciated that: between flexible pipe cushion and toilet seat, need track with rule its around rotation.If using and one design the nested flexible pipe of groove in toilet seat as track, its shortcoming is clearly: not firm and groove easily deposits the spots such as urine.For this reason, we propose a scheme and solve this difficult problem: utilize magnet to build magnetic orbit.
Two, magnetic orbit:
In the pipe of flexible pipe cushion, fill in irony particle, and magnet is installed in toilet seat, magnet is adsorbed on flexible pipe cushion in toilet seat.
From accompanying drawing 2, clearly find out, the toilet seat end face (being toilet seat and cushion contact surface) of carrying flexible pipe cushion is tilted to toilet, the similar sports palace of its shape grandstand.
This kind is designed with two kinds of objects:
1. flexible pipe, under human buttock's weight, not only bears downward pressure and deformation, and because the extruding of buttocks, flexible pipe can be to extending out.This interior inclined design is to prevent that for bearing this extruding force flexible pipe from extending out;
2. end face is interior oblique, dirt (for example urine) can be drained in toilet.
Three, flexible pipe cushion automated cleaning process:
Accompanying drawing 1 is flexible pipe cushion automated cleaning Principle of Process figure of the present invention.In figure:
The 1st, be inside plugged with the closed circular flexible pipe cushion of irony particle; The 2nd, be pressed in the pinch roller that drives hose loop to rotate around toilet on flexible pipe cushion; The 3rd, be used for drying blade water stain on flexible pipe; The 4th, be used for removing the Dirt-cleaning brush of spot on flexible pipe; 5 are mounted in magnet in toilet seat, are used for adsorbing flexible pipe and build magnetic orbit; The 6th, cleaning nozzle, this nozzle alignment Dirt-cleaning brush jet water course, to clean the spot on Dirt-cleaning brush, pours spot in 7.This nozzle connects water-closet tank, by closestool flushing valve, controlled, and also in the time of people's flushing toilet, this nozzle rinse Dirt-cleaning brush; The 7th, lead dirty pond and be communicated with in toilet, by 6, wash away the spot of getting off and come together in this and be imported in toilet.
It should be noted in the discussion above that gear or pinch roller will put unilateral bearing, for example, when toilet lid presses down, drive flexible pipe to rotate,, under the effect of unilateral bearing, in toilet lid, turn over the rotation that can not cause flexible pipe.That is to say, utilize unilateral bearing to limit flexible pipe cushion one-directional rotation, forbid its Double-directional rotary.
Limit flexible pipe one-directional rotation: clearly, aforesaidly with unilateral bearing, limit flexible pipe cushion one-directional rotation, its object is also the clean order for regular flexible pipe, first by scrubbing, scraped water and dry afterwards, can not transpose.
Further, on blade side, a sterilizing unit can also be set, for example ultraviolet germicidal lamp carries out irradiation-sterilize to flexible pipe.Further, before Dirt-cleaning brush, a liquid soap device can also be set flexible pipe is sprayed to soap lye, be beneficial to scrubbing.
Further, on cleaning nozzle side, a liquid soap device can be set, in current, mix soap lye in order to scrubbing.Further, in flexible pipe, can be full of liquid, a heater is set, for example electromagnetic heater is heated to comfortable temperature to flexible pipe, even like this in cold season, and also can warm buttocks.
The present invention has not only solved a difficult problem of mentioning in aforementioned background art, also has following beyond thought advantage: 1. flexible pipe cushion is because can deformation under buttocks pressure, thereby the buttocks of more fitting is more comfortable; 2. flexible pipe cushion inside is full of liquid, therefore can heat very easily, thereby warm buttocks makes us feeling more comfortable.
