Description

Summary electronic impulse flow control apparatus for water

The utility model relates to a kind of electronic impulse flow control apparatus for water, is used for the control of family or public bathing place bathing current.

Existing shower device is that opening water valve is continuous effluent by common water valve manual control mostly.The shower wall that occurs on the market is established a plurality of dashing and is bathed head, and each dashes the bath head and only goes out three strands of water columns, and using water flow velocity increases, and sprays to human body continuously, produces certain massage effect.Another kind of massaging shower (shower nozzle) is that mechanical type aquapulse device is installed on shower nozzle, and by the pressure and the impact generation pulse current of water, its water outlet pulse frequency is too high, pulse current DeGrain, and pulse frequency is non-adjustable.When people always washed health by rubbing with the hands when bathing in addition, total continuous effluent in fact some water-white whitecap had been taken.

The purpose of this utility model is to provide a kind of electronic impulse flow control apparatus for water, the pulse signal of the frequency adjustable that produces by the pulse generating circuit in the controller drives the opening and closing of solenoid valve through the control circuit drive circuit, make the effect of the water generates pulse current that flow through solenoid valve, can be used for the control of household water heater or other shower device and public bathing place bathing current.

The technical solution of the utility model is: the electronic impulse flow control apparatus for water, it is characterized in that: form by supply convertor (1), controller (2) and solenoid valve (3), its middle controller (2) comprises shell (4), be installed in the circuit board (5) in the shell (4), be installed in the keyboard (6) on shell (4) surface, supply convertor (1) is connected with controller (2) with lead, controller (2) is connected with solenoid valve (3) with lead, and circuit board (5) comprises pulse generating circuit I, control circuit II and drive circuit III.

The utility model compared with prior art has the following advantages:

1, pulse current frequency adjustable can be set different pulse frequencies according to different needs, and is effective when making the massage spray;

Owing to be intermittently water outlet, can save the hot water about half when 2, adopting pulse current spray, the while has also been saved and has been used to add the energy that hot water consumes;

3, volume is little, cost is low, easy to operate, be fit to the control of family expenses bath utensil and public bathing place bathing current.

The utility model is described in further detail below in conjunction with drawings and Examples.

Figure one is the utility model schematic appearance;

Figure two is the utility model controller sectional drawings;

Figure three is the utility model control circuit skeleton diagrams;

Figure four is the utility model control circuit schematic diagram first portions;

Figure five is the utility model control circuit schematic diagram second portions.

With reference to figure one and figure two, controller (2) comprises shell (4), circuit board (5) is installed in the shell (4), keyboard (6) is installed in shell (4) surface, be connected with lead between supply convertor (1) and the controller (2), be connected with lead between controller (2) and the solenoid valve (3).With reference to figure three, circuit board (5) comprises pulse generating circuit I, control circuit II and drive circuit III.With reference to figure four and figure five, the pulse generating circuit I is made up of with capacitor C 7, C8, resistance R 11～R16 IC7 time base circuit 555.Pulse frequency control circuit in the control circuit II is made up of IC8 and IC4-4 bidirectional analog switch 4066, IC9 decade unit 4017 and resistance R 17, capacitor C 9 and key switch S4.Switch S 4 is connected with the 14 pin CK input ends of IC9, is used for producing the pulse of control impuls frequency.The Q of IC9 ₀～Q ₄Control end with IC8 and IC4-4 is connected respectively, successively controlling resistance R16～R12 and V _DDEnd connects, and makes the pulse signal of the 3 pin generation different frequency of IC7.Luminous diode LED7～LED11 is the pulse frequency tutorial light.3 pin of IC7 are connected with 14 pin of IC3, send above-mentioned pulse signal to IC3.Water outlet proportion control circuit in the control circuit II is by IC5 decade unit 4017, resistance R 3, capacitor C 4 and key switch S3, and IC4-1～IC4-3, IC2-4 bidirectional analog switch, IC3 decade unit 4017, resistance R 2, capacitor C 3 are formed.Control IC5 successively at Q by Push switch S3 ₂～Q ₀15 pin that the control end of end output positive pulse control IC4 makes IC3 respectively with the Q of IC3 ₂, Q ₃And Q ₄Connect, control IC3 when 14 pin input pulse signals respectively at 3 pin Q ₀End produces the pulse signal of 1/2,1/3 and 1/4 dutycycle, has promptly reached the purpose of control water outlet proportion.Luminous utmost point pipe LED1～3 are the water outlet proportion tutorial light.Function in control circuit II conversion and starting stops control circuit by four phase inverters in IC6 six inverter buffers 4049 and key switch S1, resistance R 6, R7, capacitor C 5, two flip and flop generators compositions that key switch S2, resistance R 8, R9, capacitor C 6 are formed respectively.Push switch S1 makes the flip and flop generator upset, and control IC2-3 and IC2-2 make 3 pin and the V of C point and IC3 respectively _DDTermination is logical, to reach the purpose that control impuls water outlet and continuous effluent are the function conversion.Luminous second tube sheet LED4, LED5 are function conversion tutorial light.The connecting and disconnecting of IC2-1 among the Push switch S2 may command IC2 between C point and the resistance R 1 are the startup of controllable flow and stop.Resistance R 10 and LED 6 stop tutorial light for starting.Triode VT1 and resistance R 1, diode D1 form driving road III.Solenoid valve (3) by with the collector electrode D point of triode VT1 and diode D1 and power supply input anode V ⁺Contact E connect.IC1 is 78 serial three terminal regulators, its power supply input anode V ⁺Be connected with supply convertor (1) with lead with ground end GND.The available common transformer of supply convertor (1) and commutation diode are formed, and also can adopt switch power, no matter but with that quasi-converter, must make output voltage is safety voltage.
