Detailed Description
The core of the utility model is to provide a condensate water discharging equipment can realize the emission of comdenstion water effectively, and the cost is lower to having carried out the protection of malfunction, the solenoid valve that can not appear leading to because user's maloperation carries out the condition that lasts the emission of comdenstion water.
In order to make the technical field better understand the solution of the present invention, the following detailed description of the present invention is provided with reference to the accompanying drawings and the detailed description. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a condensate discharging device according to the present invention, the condensate discharging device may include:
a trigger switch S1 having a first end connected to the positive electrode of the first power VCC and a second end connected to the anode of the first diode D1 and the control end of the first switch transistor Q1, respectively;
a first diode D1 having a cathode connected to the second terminal of the first capacitor C1 and the anode of the second diode D2, respectively;
a first capacitor C1 with a first terminal grounded;
a first resistor R1 having a first terminal connected to a first terminal of the first capacitor C1 and a second terminal connected to a second terminal of the first capacitor C1;
a second diode D2 having a cathode connected to the control terminal of the second switching transistor Q2 and the first terminal of the first switching transistor Q1, respectively;
a first switch tube Q1 with a second end connected to ground;
a second switch tube Q2, a first end of which is connected to the positive electrode of the first power supply VCC, and a second end of which is connected to the first end of the second capacitor C2;
a second capacitor C2 having a second end grounded and discharging through the solenoid valve control circuit 10;
the solenoid valve control circuit 10 is connected with a first end of the second capacitor C2 and the positive electrode of the first power supply VCC, and is used for providing a loop for supplying power to the solenoid valve 20 for the first power supply VCC when the voltage of the second capacitor C2 is higher than a first threshold value;
a solenoid valve 20 connected to the solenoid valve control circuit 10, for discharging condensed water when power supplied from the first power source VCC is received;
when the control terminal of the switch tube receives a high level signal, the first switch tube Q1 and the second switch tube Q2 are both turned on between the first terminal and the second terminal of the switch tube.
Specifically, the specific device type of the trigger switch S1 can be selected according to actual needs, such as a conventional push-button single-pole double-throw switch. The first terminal of the trigger switch S1 is connected to the positive electrode of the first power source VCC, the second terminals are connected to the anode of the first diode D1 and the control terminal of the first switch Q1, respectively, and a user can control the first terminal of the trigger switch S1 and the second terminal of the trigger switch S1 to be in a conducting state or in an off state by operating the trigger switch S1.
The trigger switch S1 of the present application is operated such that when the user needs to drain the condensed water, the trigger switch S1 is turned on, and then the trigger switch S1 is turned off after a period of time, which is usually several seconds. In addition, even if the user forgets to control the trigger switch S1 to turn off after turning on the trigger switch S1, the scheme of the present application does not result in the drainage of condensed water for an excessively long time. The condensate water is continuously discharged for an excessively long time, which may cause an abnormal use. For example, when the condensed water discharge device of the present application is a condensed water discharge device in a device for treatment using drug vapor, if the condensed water is continuously discharged during use, forgetting to turn off the device may result in dilution of the drug components, and decrease the treatment effect.
As can be seen from the circuit connection relationship, after the trigger switch S1 is turned on, the first power source VCC can charge the first capacitor C1 through the trigger switch S1 and the first diode D1, and usually, the first capacitor C1 can be fully charged in a few seconds. After the user operates the trigger switch S1 to turn on for several seconds, the trigger switch S1 may be operated to turn off, the first capacitor C1 may discharge through the first resistor R1, at this time, the control terminal of the second switch Q2 is at a high level, so that the first terminal of the second switch Q2 and the second terminal of the second switch Q2 are turned on, so that the first power VCC may charge the second capacitor C2 through the second switch Q2 at this time, and the second capacitor C2 may be fully charged usually within several seconds.
After the trigger switch S1 is turned off, the first capacitor C1 discharges through the first resistor R1, when the voltage of the first capacitor C1 is not enough to turn on the second switch Q2, the second switch Q2 is turned off, usually within a period of several seconds to ten and several seconds, the first capacitor C1 can be discharged, and the discharge time of the first capacitor C1 can be adjusted by setting and adjusting the resistance value of the first resistor R1. Of course, the discharging time of the first capacitor C1 is not so long as it does not affect the scheme, and the discharging time is not so long as it is too long, because when the discharging time is too long and the second switch Q2 is turned on for a long time, the solenoid valve 20 may discharge the condensed water for a long time.
When the second switch Q2 is turned on, the first power VCC may charge the second capacitor C2 through the second switch Q2. When the voltage of the second capacitor C2 is higher than the first threshold, the solenoid valve control circuit 10 may provide a circuit for the first power source VCC to supply power to the solenoid valve 20, so that the solenoid valve 20 discharges condensed water when receiving power from the first power source VCC. After the second switch Q2 is turned off, the second capacitor C2 is continuously discharged through the solenoid valve control circuit 10, and when the voltage of the second capacitor C2 is lower than the first threshold, the solenoid valve 20 is not powered by the first power source VCC, and the discharge of the condensed water is stopped. It can be seen that the solution of the present application does not drain the condensed water for a long time.
Moreover, even if the user forgets to turn off the trigger switch S1 due to misoperation, the situation that the condensed water is continuously discharged cannot occur, that is, the scheme of the application has a protection function of misoperation. Specifically, it can be known from the circuit structure that when the trigger switch S1 is turned on, the control terminal of the first switch tube Q1 is at a high level, and at this time, the first terminal of the first switch tube Q1 is turned on with the second terminal of the first switch tube Q1, so that the control terminal of the second switch tube Q2 is at a low level, that is, the second switch tube Q2 is not turned on, and therefore the second capacitor C2 is not charged, and the solenoid valve 20 cannot discharge the condensed water.
This application has limited the discharge circuit of first electric capacity C1 through first diode D1 and second diode D2, and is concrete, if do not set up first diode D1, first electric capacity C1 can discharge to two directions for first switch tube Q1 switches on, and then makes second switch tube Q2 unable switch on, and the scheme can't carry out the emission of comdenstion water. The second switch tube Q2 can avoid the dangerous situation caused by the current flowing backwards due to the damage of the second switch tube Q2.
In the scheme of the present application, the first switch Q1, the second switch Q2, and the third switch Q3 in the following text are all conducted between the first end and the second end when the control end receives a high level signal, and the specific types of the adopted devices can be set and selected according to actual needs, for example, the devices can be selected as NPN-type triodes, MOS transistors, and the like, as long as the requirements of the present application are met. In the drawings of the present application, embodiments of low-cost NPN transistors are used.
In a specific embodiment of the present invention, referring to fig. 2, it may further include:
a second resistor R2 having a first end connected to the cathode of the second diode D2 and a second end connected to the control end of the second switch Q2 and the first end of the first switch Q1, respectively;
a third resistor R3 having a first end connected to the second end of the trigger switch S1 and a second end connected to the control end of the first switch tube Q1;
a fourth resistor R4 with a first end connected with the second end of the trigger switch S1 and a second end grounded.
In consideration of the fact that the bearable current of the first switching tube Q1 and the second switching tube Q2 is low, in this embodiment, the current is limited by the second resistor R2 and the third resistor R3, which is beneficial to ensuring the safe operation of the first switching tube Q1 and the second switching tube Q2.
The fourth resistor R4 can provide a quiescent point of the first switch Q1, thereby ensuring reliable turn-off of the first switch Q1.
The specific circuit configuration of the solenoid valve control circuit 10 can be set according to actual needs, and only a discharge circuit needs to be provided for the second capacitor C2, and a loop for supplying power to the solenoid valve 20 is provided for the first power VCC when the voltage of the second capacitor C2 is higher than the first threshold, for example, in a specific embodiment of the present invention, referring to fig. 3, the solenoid valve control circuit 10 includes:
the first control end is connected with the positive pole of a first power supply VCC, the second control end is connected with the first end of a third switch tube Q3, the first controlled end is connected with the positive pole of the first power supply VCC, and the second controlled end is connected with the positive pole of a water drainer of the electromagnetic valve 20;
a third switching tube Q3, the control end of which is connected to the first end of the second capacitor C2, and the second end of which is connected to the negative electrode of the drain of the solenoid valve 20 and grounded;
when the control terminal of the third switching tube Q3 receives a high-level signal, the first terminal and the second terminal of the third switching tube Q3 are connected.
In this embodiment, the solenoid valve control circuit 10 is constituted by only one relay K1 and the third switching tube Q3, and has a simple circuit structure and high reliability.
Specifically, as can be seen from the circuit structure, when the voltage of the second capacitor C2 is higher than the first threshold, the third switch tube Q3 is turned on, that is, the first end and the second end of the third switch tube Q3 are turned on, the relay K1 is attracted, so that the first controlled end and the second controlled end of the relay K1 are turned on, the first power VCC can supply power to the electromagnetic valve 20 through the relay K1, specifically, the power is supplied to the drain of the electromagnetic valve 20, and therefore the drain of the electromagnetic valve 20 discharges the condensed water.
After the second switch tube Q2 is turned off, as the second capacitor C2 discharges, when the second capacitor C2 discharges until its voltage is lower than the first threshold, the third switch tube Q3 turns off, so that the relay K1 turns off, and the solenoid valve 20 stops draining the condensed water. The first threshold depends on the turn-on voltage of the third switching tube Q3.
The discharging time of the second capacitor C2 affects the discharging time of the condensed water, and therefore, in order to more conveniently control the discharging time of the second capacitor C2, i.e. the discharging time of the condensed water, in an embodiment of the present invention, referring to fig. 4, the method may further include:
and a variable resistor RX having a first terminal connected to the first terminal of the second capacitor C2 and a second terminal connected to the control terminal of the third switching tube Q3.
The resistance value of the variable resistor RX can be conveniently adjusted, and the discharge time of the second capacitor C2 can be adjusted by adjusting the resistance value of the variable resistor RX, so that the discharge time of condensed water is changed, and the flexibility of the scheme is greatly improved.
In a specific embodiment of the present invention, referring to fig. 4, it may further include:
a fifth resistor R5 having a first end connected to the positive electrode of the first power VCC and a second end connected to the first end of the sixth resistor R6 and the first end of the third capacitor C3, respectively;
a third capacitor C3 with a second terminal grounded;
a sixth resistor R6 with a second end connected with the control end of the fourth switching tube Q4;
a fourth switch tube Q4, a first end of which is connected to the positive electrode of the first power supply VCC, and a second end of which is connected to the first end of the second capacitor C2;
when the control terminal of the fourth switch transistor Q4 receives the low level signal, the first terminal and the second terminal of the fourth switch transistor Q4 are conducted.
In this embodiment, it is considered that in the actual use process, when the device is powered on, one time of discharging the condensed water is usually required, that is, the condensed water remained in the last use process is discharged. However, the user does not necessarily think of doing this every time he uses it, so in this embodiment, the drainage of condensed water can be triggered automatically every time he powers on.
Specifically, as can be seen from the circuit structure, after power is turned on, since the voltage across the third capacitor C3 cannot change suddenly, the control terminal of the fourth switch Q4 is a low-level signal, and at this time, the first terminal and the second terminal of the fourth switch Q4 are turned on, so that the first power VCC can charge the second capacitor C2 through the fourth switch Q4, thereby achieving the discharge of the condensed water. As the third capacitor C3 is charged, the voltage of the third capacitor C3 rises, and the fourth switch Q4 is turned off. The fourth switch tube Q4 can adopt devices such as PNP type triode, MOS pipe, can realize the purpose of this application can.
Further, in a specific embodiment of the present invention, the present invention may further include:
and a third diode D3 having a cathode connected to the first control terminal of the relay K1 and an anode connected to the second control terminal of the relay K1.
In this embodiment, a third diode D3 is added to form a discharge loop of the induced electromotive force, which is advantageous for protecting circuit devices, in view of the fact that the relay K1 belongs to a magnetic component and generates the induced electromotive force after power failure.
Similarly, the electromagnetic valve 20 also belongs to a magnetic component, and therefore, may further include:
the fourth diode D4, which has a cathode connected to the positive electrode of the drain of the solenoid valve 20 and an anode connected to the negative electrode of the drain of the solenoid valve 20, forms a discharge circuit with the fourth diode D4, thereby protecting the circuit. In addition, in the drawings of the present application, the specific structure of the water drainer of the electromagnetic valve 20 is not shown, and can be set according to actual needs, which does not affect the implementation of the present invention.
Furthermore, in a specific embodiment of the present invention, the present invention may further include:
and the display circuit is connected with the anode of the first power supply VCC and is used for displaying after receiving the power supply of the first power supply VCC.
Because the display circuit is connected with the positive electrode of the first power supply VCC, whether the first power supply VCC is electrified or not can be displayed through the display circuit. The voltage level of the first power source VCC may be set and adjusted according to actual needs, and may be 12V, for example.
In the embodiment of fig. 4, the display circuit specifically includes:
a seventh resistor R7, the first end of which is connected with the anode of the first power supply VCC, and the second end of which is connected with the anode of the light emitting diode D5;
and a light emitting diode D5 with its cathode grounded.
The display circuit in this embodiment is composed of the seventh resistor R7 and the light emitting diode D5, the circuit structure is simple, the reliability is high, and the user can determine whether the first power VCC is charged by observing whether the light emitting diode D5 is lit.
In the scheme of this application, through trigger switch S1, first diode D1, first electric capacity C1, first resistance R1, second diode D2, first switch tube Q1, second switch tube Q2, second electric capacity C2, solenoid valve control circuit 10 and solenoid valve 20 realize the emission control to the comdenstion water, what chooseed for use all is basic components and parts, circuit structure is simple easily to implement, need not to use singlechip or clock chip to realize control as in the traditional scheme, consequently, the scheme cost of this application is lower. In addition, the condensed water discharging device also has a protection function of misoperation, and abnormal conditions caused by discharging the condensed water for too long time can not occur. Specifically, when the user operates the trigger switch S1 to close and then opens the trigger switch S1, the condensate water drain device of the present application can drain the condensate water. When the trigger switch S1 is turned on, the first capacitor C1 is charged, and when the trigger switch S1 is turned off, the first capacitor C1 is discharged through the first resistor R1, the control terminal of the second switch tube Q2 is at a high level, so that the first terminal of the second switch tube Q2 and the second terminal of the second switch tube Q2 are connected, the second capacitor C2 may be charged with the first power VCC, so that the voltage of the second capacitor C2 is higher than a first threshold, the solenoid valve control circuit 10 may provide a loop for the first power VCC to supply power to the solenoid valve 20, and the solenoid valve 20 may discharge condensed water when receiving the power of the first power VCC. After the first capacitor C1 is discharged, the control terminal of the second switch Q2 is at a low level, so that the second switch Q2 is turned off. The second capacitor C2 is discharged by the solenoid valve control circuit 10, and when the voltage is lower than the first threshold, the solenoid valve 20 does not discharge any more condensed water. It can be seen that in normal use, the scheme of this application has realized the emission of comdenstion water, and the condition of continuous emission can not appear. Further, in the solution of the present application, even if the user forgets to turn off the trigger switch S1 after operating the trigger switch S1 to close, the solenoid valve 20 does not cause continuous discharge of condensed water. This is because even if the user forgets to turn off the trigger switch S1 after operating it, the first switch Q1 is turned on, and when the first switch Q1 is turned on, the control terminal of the second switch Q2 is grounded, so that the second capacitor C2 cannot be charged by the first power source VCC, i.e., the malfunction is avoided. To sum up, the scheme of this application can realize the emission of comdenstion water effectively, and the cost is lower to the protection of malfunction has been carried out, the condition that the solenoid valve 20 that leads to because the user maloperation carries out the continuous emission of comdenstion water can not appear.
