Abstract
The invention discloses a toilet water-saving device, which comprises an electromagnetic valve, a human body infrared inductive switch, a microcomputer time control switch for controlling the on-off time of the whole device, and a time relay for matching the human body infrared inductive switch to delay the water supplying to a water tank. Coils of the time relay are connected in series with the human body infrared inductive switch to form an inductive branch, a normally-open contact of the time relay is connected in series with the electromagnetic valve to form a water supply branch, and the inductive branch is connected in parallel with the water supply branch and is connected in series with the microcomputer time control switch. The toilet water-saving device has the advantages of simple structure, low production cost, easy installation and maintenance and obvious water-saving effect.
Description
Technical field
The present invention relates to a kind of water saving fixtures, especially a kind of centralized bath public lavatory water saving fixtures.
Background technology
There is huge water resource waste problem in present concentrated flushing public toilet, concentrated flushing public toilet mostly is uninterrupted bath in a day 24 hours, can not control water supply volume according to peak period and the low peak period that use in the public lavatory, more can not wash by water according to use amount, do not accomplish the people dashes for a long time, the people is Shaochong after a little while, does not dash during the no one.And the public lavatory is used and to be had especially significantly peak period and low peak period, and especially between 22 of nights to next day 5:00 AM, the public lavatory utilization rate is zero substantially, but this time period be the maximum stage of hydraulic pressure in one day, water resource waste is bigger.
Summary of the invention
The technical problem to be solved in the present invention is for overcoming above-mentioned deficiency, and a kind of water saving device for latrine simple in structure, easy to use is provided, its can according to concrete public lavatory use period and have nobody to go into the lavatory and at regular time and quantity pouring wash away, save a large amount of waters.
The present invention takes following technical measures: a kind of water saving device for latrine, comprise electromagnetic valve, and the human body infrared sensing switch also comprises: the micro computer time control switch is used to control power on/off time of whole device; The time relay is used for cooperating with time-delay to cistern water supply with the human body infrared sensing switch; After being in series, time relay coil and human body infrared sensing switch constitute the induction branch road, constitute the water supply branch road after time relay normally open contact and described electromagnetic valve are in series, be in series together with the micro computer time control switch after induction branch road and water supply branch road are in parallel.
On described induction branch road, be provided with an above human body infrared sensing switch, and link together in parallel.
On described water supply branch road, also be provided with standby gate valve, be connected in parallel on the two ends of described electromagnetic valve.
The invention has the beneficial effects as follows: simple in structure, cost of production is low, is easy to installation and maintenance, and water-saving result is very remarkable.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present invention
Fig. 2 is a circuit structure schematic diagram of the present invention
The specific embodiment
As shown in the figure, a kind of water saving device for latrine comprises electromagnetic valve 1, and human body infrared sensing switch 2 also comprises: micro computer time control switch 3 is used to control power on/off time of whole device; The time relay 5 is used for cooperating with time-delay to water tank 8 water supply with human body infrared sensing switch 2; After being in series with human body infrared sensing switch 2, time relay coil 4 constitutes the induction branch road, time relay normally open contact 6 constitutes the water supply branch road after being in series with described electromagnetic valve 1, is in series together with micro computer time control switch 1 after induction branch road and water supply branch road are in parallel.
On described induction branch road, be provided with an above human body infrared sensing switch 2, and link together in parallel.
On described water supply branch road, also be provided with standby gate valve 7, be connected in parallel on the two ends of described electromagnetic valve 1.
The dynamic duty process of this water saving device is: micro computer time control switch 1 uses peak period and the different periods of low ebb phase to have a power failure, send electricity according to the public lavatory, carries out the rough water supply control of the first step.When micro computer time control switch 2 sent electricity, other element entered armed state.When the people goes into the lavatory, closed from 2 actions of his nearest human body infrared sensing switch, this moment time relay coil 4 electric, 6 timing closings of time relay normally open contact, electromagnetic valve 1 electronic work begins to supply water to water tank 8.When the peak period toileting person for a long time, always have in a plurality of human body infrared sensing switchs 2 closed, electromagnetic valve 1 all the time electric water supply, water yield abundance has satisfied the water demand on peak.At low peak period, the time relay 5 continues to play a role, and delays time and supplies water to water tank 8, and the water in the water tank 8 is added up with the number of users that enters, and reaches the further effect of water saving.Human body infrared sensing switch 2 can be adorned one every a urinal, always has one for a long time the people and is in closed condition, in people's then further science water saving after a little while.
Be parallel with standby gate valve 7 at the two ends of electromagnetic valve 1, standby gate valve 7 is in normal off status, when the system failure or power failure, can open standby gate valve 7 and supply water to water tank 8.Before water tank 8, water supply gate valve 9 can also be installed, be used for regulating the water velocity of water supply.
Claims (3)
1, a kind of water saving device for latrine comprises electromagnetic valve, and the human body infrared sensing switch is characterized in that also comprising: the micro computer time control switch is used to control power on/off time of whole device; The time relay is used for cooperating with time-delay to cistern water supply with the human body infrared sensing switch; After being in series, time relay coil and human body infrared sensing switch constitute the induction branch road, constitute the water supply branch road after time relay normally open contact and described electromagnetic valve are in series, be in series together with the micro computer time control switch after induction branch road and water supply branch road are in parallel.
2, water saving device for latrine according to claim 1 is characterized in that described induction branch road is provided with an above human body infrared sensing switch, and links together in parallel.
3, water saving device for latrine according to claim 1 and 2 is characterized in that also being provided with standby gate valve on the described water supply branch road, is connected in parallel on the two ends of described electromagnetic valve.
