Abstract
The utility model provides an unpressurized dirt-proof fully automatic flushing device for a toilet. When a person squats or sits on a lever panel (13) to relieve nature, the water in an (A) chamber of a water tank flows into a (B) chamber via an automatic control valve. When the person leaves, the water in the (B) chamber flows into a squatting toilet or a sitting toilet via a valve port. An anti-fouling valve is arranged on a standpipe (19) connected with an indoor water supply. The refluxing pollution can be avoided. The water tank and the control component of the flushing device for a toilet do not bear the water pressure. The utility model has the advantages of easy production, easy control, working without the electricity and simple structure, and can normally work under the condition of inadequate water pressure and a small water supply pipe.
Description
The utility model belongs to a kind of water supply and drainage equipment.
Existing lavatory toilet flushing device tool is flushing valve and wc flushing cistern.These two kinds of products leak because of being easy to damage, and because of the unclean communicate illness of hand switch, flushing is dirty smellyly be can't bear because of people are reluctant to discharge water with hand after an action of the bowels.In addition, owing to produce negative pressure when cutting off the water in the water service pipe, foul smell between the lavatory or the ponding in the urinal can flow back to the water service pipe from the delivery port of above-mentioned wc flushing cistern and flushing valve, cause backflow pollution, and wherein the consequence of sewage backflow is hardly imaginable.
The purpose of this utility model is that a kind of full-automatic toilet flusher that huge numbers of families use that is suitable for that prevents the backflow pollution performance that has will be provided, and the worry of going into the lavatory for using water wisely, the cross infection that wards off disease, elimination people creates conditions.
The utility model is achieved in that installs the antifouling valve (being vacuum brake) that can eliminate negative pressure in the pipe on away from the indoor Pipeline in lavatory, antifouling valve is higher than all water appliances.Described water service pipe is communicated with a water tank that is separated into two Room by float valve.There are two connecting legs the water tank bottom surface, and its upper end communicates with two Room of water tank respectively, and the lower end communicates with two interfaces of an automatic control valve respectively.The valve rod lower end of automatic control valve links to each other with the lever plate of a band hinge.When the drawdown in the water service pipe, antifouling valve allows the air of outside enter water service pipe, is unlikely the generation negative pressure, and the ponding at the stink between the lavatory, the sewage in the urinal and place, water service pipe crack also just can't reflux.As the people go into the lavatory squat or when being sitting on the lever plate, under the control of automatic control valve, the water in the water tank does not enter urinal, the people relieves oneself and finishes when leaving, the automatic control valve time-delay flushing that discharges water, the current in the water tank wash by intact promptly stopping.
Control assembly of the present utility model is pressure-bearing not all, so be easy to make and control; Because it has disposed an antifouling valve, so can prevent backflow pollution effectively.In addition, owing to its not electricity consumption, do not choose and do any operation, simple in structure, the restriction that is not subjected to hydraulic pressure and water service pipe size, so applied range.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.Fig. 1 is the sectional view of the toilet flusher that proposes of the utility model, and wherein pan or water closet do not draw.Describe the details and the working condition of this toilet flusher in detail below in conjunction with Fig. 1.
Antifouling valve is made up of valve seating (1), sealing ring (2), inverted cup-shaped float (3), antifouling valve body (4), and it is installed in the threeway (5) on the water supply riser (19).
Water tank (7) is separated into (A), (B) two Room, forms the water tank assembly with the float valve (6) of its inside.
Automatic control valve is made up of valve gap (9), valve plug (10), valve body (11), gland (12), valve rod (14), filler (15) and compression spring (16), and the valve rod lower end links to each other with the lever plate (13) of a band hinge.
Above-mentioned antifouling valve, water tank assembly, automatic control valve, lever plate are formed by connecting by threeway (5), tubule (8), bassoon (18) and 90 ° of elbows (17) does not have the antifouling full-automatic toilet flusher of pressure.
When the drawdown in the water supply riser (19), float (3) falls, and allows the hole of outside air from valve seating (1) enter the water supply riser (19), destroys vacuum state, thereby prevents the backflow pollution that causes because of negative pressure.When water level rose, the air in the water supply riser (19) was discharged from the hole on the valve seating (1), and final water holds up float (3), and the hole on the valve seating (1) is sealed, and does not allow water excessive.
When toilet flusher left unused, the water in the water supply riser (19) flow to the A chamber of water tank (7) by float valve (6), and the following mouth of a river of A chamber is sealed by the last conical surface of valve plug (10).When A chamber water level reached setting height, float valve (6) stopped into water.
Someone go into the lavatory squat or when being sitting in lever plate (13) and going up, valve rod (14) drives that valve plug (10) is descending, the last conical surface of valve plug (10) is opened, the following conical surface is blocked the hole under it.Water in water tank (7) the A chamber flows in the B chamber with regard to the inner chamber by tubule (8), valve gap (9), valve body (11), 90 ° of elbows (17) and bassoon (18) like this, float valve (6) is to A chamber supplementing water simultaneously, when the water level of A, B two Room reached setting height, float valve (6) stopped feedwater.
When the people left lever plate (13), valve rod (14) promotion valve plug (10) was up, and the following conical surface of valve plug (10) is opened, and the last conical surface is blocked the hole on the valve gap (9).Like this, A chamber water level is constant, and the water in the B chamber is through the inner chamber of bassoon (18), 90 ° of elbows (17) and valve body (11), and the delivery port K from valve body (11) rushes in urinal at last, has flowed promptly and has stopped.
