Description
Technical field
The utility model relates to a kind of water saving fixtures that are installed in the washroom, particularly washroom automatic water saving cistern.
Background technology
At present, the water tank of flushing toilet bowl also is installed in much the crowd is dense washroom, public arena such as hospital, hotel, school, be installed with on the wash tub pipe of water tank and have spring from resetting the Water-saving valve of valve, this Water-saving valve can automatically reset in the regular hour and close water pipe to realize the water saving purpose.Its weak point is that this spring is after the Water-saving valve of the valve that resets has used of a specified duration, to such an extent as to reason such as aging and corrosion makes this valve closing time prolong some valve greatly can not to close automatically more at all owing to spring, cause the water whole day trickling in some washroom, thereby cause a large amount of freshwater resources to be wasted.
The utility model content
The purpose of this utility model is to provide a kind of washroom automatic water saving cistern, only just urinal is washed when having the people to use the washroom, can close current automatically after the people walks, thereby can control fresh water dosage effectively, saves freshwater resources.
The purpose of this utility model is achieved in that a kind of washroom automatic water saving cistern, comprise casing, the water injection pipe of water filling in casing, the electric control box that control relay circuit is housed and human body induction control switch, the automatic jettison gear of siphon is housed in the casing, electromagnetic valve is installed on water injection pipe, on a side inwall of casing, buoyancy switch is being set, the human body induction control switch links to each other with electric control box by lead, and electric control box is connecting electromagnetic valve and buoyancy switch by lead respectively.
When the utility model uses, the human body induction control switch is installed in the urinal corresponding site, when the people enters washroom use urinal, the human body induction control switch conduction, control relay circuit control electromagnetic valve in the electric control box is opened water filling in water tank, after the water in the water tank reaches certain water level, buoyancy switch is subjected to its circuit of buoyancy and connects, guarantee that electromagnetic valve can continue water filling in water tank, cut off the human body induction control Switching Power Supply simultaneously, after water in the water tank is full, the automatic jettison gear of siphon just begins to wash by water in urinal, drawdown in the water tank, and the buoyancy switch circuit disconnects, the electromagnetic valve cut-out water injecting pipeline that also cuts off the power supply stops water filling in water tank.When the someone entered the washroom again, the conducting again of human body induction control switch repeated above-mentioned steps.Therefore, the utility model only just washes urinal when having the people to use the washroom, can stop automatically discharging water after the people walks, thereby can control fresh water dosage effectively, save freshwater resources, be particularly useful for being installed in hospital, hotel, school etc. the crowd is dense in the washroom of public arena.The utility model is simple in structure, and its work operation need not the toilet user be started to intervene the reliability height.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a syndeton schematic diagram of the present utility model;
Fig. 2 is the control relay circuit figure in the utility model electric control box;
Fig. 3 is the another kind of control relay circuit figure in the utility model electric control box.
The specific embodiment
A kind of washroom automatic water saving cistern as shown in Figure 1, comprises the water injection pipe 3 of casing 4, water filling in casing 4, the electric control box 9 that control relay circuit is housed and human body induction control switch 11, and water injection pipe 3 is connected on the upper hose 1.The automatic jettison gear 10 of siphon is housed in the casing 4, electromagnetic valve 2 is installed on water injection pipe 3, on a side inwall of casing 4, buoyancy switch 5 is being set, human body induction control switch 11 links to each other with electric control box 9 by lead, and electric control box 9 is connecting electromagnetic valve 2 and buoyancy switch 5 by lead respectively.
As shown in Figure 1, buoyancy switch 5 is the column casing shape, its open bottom end and end face is being provided with the capping with air vent, suit the support bar that its lower end has a floating drum 8 in this buoyancy switch 5, support bar stretches out from the air vent of buoyancy switch 5 cappings, be positioned on the support bar top body of rod of buoyancy switch 5 conductive plate 6 is being set, conductive contact 7 is being set on the bottom surface of buoyancy switch 5 cappings, conductive plate 6 matches with conductive contact 7.
The effect of buoyancy switch 5 is after the water in the casing 4 reaches certain water level, floating drum 8 drives support bar and rises, the conductive plate 6 connection circuit that contacts with conductive contact 7, and after the water level in the casing 4 reduces, floating drum 8 drives support bar and descends, and conductive plate 6 disengages the cut-out circuit again with conductive contact 7 and cuts out electromagnetic valve.Therefore, the effect of this buoyancy switch 5 can also adopt existing water-level control apparatus to realize.
Human body induction control switch 11 is photosensitive switch, infra-red sensor switch or near switch, and whether the someone enters uses urinal in the washroom in order to perception.
Control relay circuit as shown in Figure 2, when using urinal in the people enters the washroom, human body induction control switch A connects, relay K 1 energising, the closed engage relay K2 of its constant open contact K1 makes electromagnetic valve C energising water filling in water tank then; When relay K 2 energisings, this relay constant close contact K2 that is cascaded with human body induction control switch A disconnects, and cuts off the power supply of human body induction control switch A.When the water in the water tank reaches certain water level, buoyancy switch B connects, relay K 3 energisings with this buoyancy switch B is cascaded continue as electromagnetic valve C power supply, continue water filling in water tank, after the water in the water tank is full, water is washed by water in urinal from the automatic jettison gear 10 of siphon, drawdown in the water tank, and buoyancy switch B disconnects, cut off the power supply of electromagnetic valve C, stop water filling in water tank.When someone again enters when using urinal in the washroom, human body induction control switch A conducting again repeats above-mentioned steps.
As shown in Figure 3, this control circuit has been done some simplification on control circuit basis shown in Figure 2, also can realize the control function that circuit is identical as shown in Figure 2.Control circuit of the present utility model is not limited to so, and those skilled in the art can also adopt other forms of control circuit.
