Abstract
The utility model discloses a control circuit of an automatic flushing urinal, which comprises a main control circuit, an electromagnetic valve and a detection circuit. The electromagnetic valve and the detection circuit are electrically connected with the main control circuit. The detection circuit consists of a hall sensor arranged on the main body of the urinal, and a permanent magnet arranged at a corresponding position on a door. The detection circuit is low in cost, so that the cost of a product is reduced. The detection mode of the detection circuit is realized through the hall sensor and the permanent magnet, thus is simple and reliable to control. Meanwhile, the misoperation is avoided.
Description
Technical field
The utility model relates to a kind of sanitaryware, particularly a kind of control circuit of auto-flushing urinal.
Background technology
Existing urinal all is provided with flushometer, and this flushometer is between the flushing delivery port of inlet channel and urinal, valve to be set to realize, the control mode of this valve has automatic control and manually controls two kinds; Manually control is unhygienic; And people often forget bath, and automatic control mode is an infrared induction, and the infrared-sensing type cost is high; Interference free performance is poor, and sensitivity is low.
The inventor has designed a kind of urinal with door; The structure of this urinal is as shown in Figure 1, and this urinal is made up of with the door body B that is hinged on urinal main body one side the urinal main body A, beats opening door body in use; After finishing using, close a body; The appearance of this urinal has improved the aesthetic property of washroom, and the washroom used with of men and women especially is like family or public place.The utility model is the urinal to this kind structure, a kind of auto-flushing control circuit of design.
Summary of the invention
In order to overcome the deficiency of prior art, the utility model provides a kind of control simple, reliable auto-flushing urinal control circuit.
The utility model solves the technical scheme that its technical problem adopted:
A kind of auto-flushing urinal control circuit comprises:
Electromagnetic valve, water inlet end is communicated with inlet channel, and the water side is communicated with the flushing delivery port of urinal, receives the control of governor circuit, when bath, opens the formation water stream channel;
Testing circuit, a door body that is used to detect urinal opens or closes;
Governor circuit, its input is electrically connected with testing circuit, output is electrically connected with electromagnetic valve, the door body open with or close after send control instruction and make electromagnetic valve open bath;
Power circuit is for above-mentioned circuit provides working power;
Said testing circuit comprises the Hall element that is installed on the urinal main body and is installed in a permanent magnet of body correspondence position.
Said governor circuit is connected with the low pressure alarming circuit.
Said low pressure alarming circuit comprises low-voltage testing circuit and alarm lamp.
Said governor circuit connects electromagnetic valve through drive circuit.
The beneficial effect of the utility model is: the testing circuit of the utility model constitutes by being installed in the Hall element on the urinal main body and being installed in a permanent magnet of body correspondence position; The cost of testing circuit is low; Can reduce the cost of product; Adopt the detection mode control of Hall element and permanent magnet simple, reliable, misoperation can not take place.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the urinal described in the background technology;
Fig. 2 is the installation site structural representation of Hall element, permanent magnet;
Fig. 3 is the control circuit functional-block diagram of the utility model.
The specific embodiment
With reference to Fig. 2, Fig. 3, a kind of auto-flushing urinal control circuit is applicable to the urinal of being with the door body, and this control circuit comprises:
Electromagnetic valve 1, water inlet end is communicated with inlet channel, and the water side is communicated with the flushing delivery port of urinal, receives the control of governor circuit, when bath, opens the formation water stream channel.
Testing circuit 2, a door body that is used to detect urinal opens or closes; This testing circuit 2 comprises the Hall element 5 that is installed on the urinal main body and is installed in a permanent magnet of body correspondence position 6.
Governor circuit 3, this circuit is mainly single chip circuit, its input is electrically connected with testing circuit 2, output is electrically connected with electromagnetic valve 1, the door body open with or close after send control instruction and make electromagnetic valve 1 open bath.
Power circuit 4, for above-mentioned circuit provides working power, the power supply of this power circuit is from dry cell, and its effect is that the voltage with dry cell is converted into and adapts to the required voltage of different circuit workings.
Said governor circuit 3 is connected with low pressure alarming circuit 7; This low pressure alarming circuit 7 comprises low-voltage testing circuit 8 and alarm lamp 9, and alarm lamp 9 can directly be electrically connected with low-voltage testing circuit 8, also can be electrically connected with governor circuit; When cell voltage is not enough; Low pressure alarming circuit 7 sends the cell voltage shortage signal, lights alarm lamp 9, and perhaps low pressure alarming circuit 7 at first sends the undertension signal and gives governor circuit; Light alarm lamp 9 by governor circuit 3, inform that the user changes battery.
Since the signal of telecommunication that sends of single-chip microcomputer a little less than, generally can not directly drive electromagnetic valve 1, therefore, in the utility model, said governor circuit connects electromagnetic valves 1 through drive circuit 10.
The operating principle of above circuit is identical with traditional infrared-sensing type, and different just testing circuits adopt Hall element and permanent magnet, and the sensing mode of Hall element and permanent magnet also belongs to prior art.
The course of work of the utility model is, after a door body was opened, permanent magnet was away from Hall element, and Hall element detects permanent magnet and leaves; Send low level or high level signal and represent that to governor circuit a body opens, governor circuit sends the signal controlling electromagnetic valve and opens bath in 3 seconds, moistening urinal; The bath rear electromagnetic valve that finishes is closed automatically, finishes in urine, closes a body; Permanent magnet is near Hall element, Hall element detect permanent magnet near, send low level or high level signal and represent that to governor circuit a body closes; Governor circuit sends the signal controlling electromagnetic valve and opens bath in 6 seconds, and the bath rear electromagnetic valve that finishes is closed automatically, realizes auto-flushing; The utility model adopts the detection mode control of Hall element and permanent magnet simple, reliable, misoperation can not take place.
