[0045] By applying the technical solution provided in the embodiment of the present invention, the discharge control of condensed water is realized by triggering a switch, a first diode, a first capacitor, a first resistor, a second diode, a first switch tube, a second switch tube, a second capacitor, a solenoid valve control circuit and a solenoid valve. All basic components are selected, and the circuit structure is simple and easy to implement. There is no need to use a single-chip microcomputer or a clock chip to realize control as in the traditional solution, so the solution cost of the present application is low. In addition, the condensed water discharge device of the present application also has a protection function of malfunction, and there will be no abnormal situation caused by draining condensed water for too long. Specifically, the user needs to operate the trigger switch to close, and then disconnect the trigger switch, and the condensed water discharge device of the present application can discharge condensed water. When the trigger switch is closed, the first capacitor is charged, and after the trigger switch is disconnected, the first capacitor is discharged through the first resistor, and the control end of the second switch tube is high, so that the first end of the second switch tube and the second end of the second switch tube are connected, and the second capacitor can be charged by the first power supply, so that the voltage of the second capacitor is higher than the first threshold, and the solenoid valve control circuit can provide a circuit for the first power supply to supply power to the solenoid valve, and the solenoid valve can discharge condensed water when receiving power from the first power supply. After the first capacitor is discharged, the control end of the second switch tube is at a low level, so that the second switch tube is turned off. The second capacitor is discharged through the solenoid valve control circuit, and when the voltage is lower than the first threshold, the solenoid valve no longer discharges condensed water. It can be seen that in normal use, the scheme of the present application realizes the discharge of condensed water, and there will be no continuous discharge. Further, in the scheme of the present application, even if the user forgets to disconnect the trigger switch after the trigger switch is closed, the solenoid valve will not cause the continuous discharge of condensed water. This is because after the user operates the trigger switch to close, even if he forgets to turn it off, since the first switch tube is turned on at this time, and when the first switch tube is turned on, the control end of the second switch tube is grounded, so the second capacitor cannot be charged by the first power supply, that is, it plays a role in avoiding misoperation. In summary, the scheme of the present application can effectively realize the discharge of condensed water, with low cost, and protection against misoperation is performed, and there will be no continuous discharge of condensed water by the solenoid valve due to user misoperation.

[0051] The core of the present invention is to provide a condensate discharge device, which can effectively discharge condensate, has low cost, and has protection against malfunction, so that the solenoid valve will not continuously discharge condensate due to user's misoperation.
[0052] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0053] Please refer to Figure 1 , Figure 1 The structure diagram of a condensate discharge device in the present invention is shown in FIG. 1 , and the condensate discharge device may include:
[0054] A trigger switch S1 having a first end connected to the positive electrode of a first power source VCC and a second end connected to the anode of a first diode D1 and the control end of a first switch tube Q1;
[0055] A first diode D1 having a cathode connected to the second end of the first capacitor C1 and the anode of the second diode D2 respectively;
[0056] A first capacitor C1 with a first terminal grounded;
[0057] A first resistor R1 having a first end connected to a first end of a first capacitor C1 and a second end connected to a second end of the first capacitor C1;
[0058] A second diode D2 having a cathode connected to the control end of the second switch tube Q2 and the first end of the first switch tube Q1 respectively;
[0059] A first switch tube Q1 with a second terminal grounded;
[0060] A second switch tube Q2 having a first end connected to the positive electrode of the first power supply VCC and a second end connected to the first end of the second capacitor C2;
[0061] A second capacitor C2 whose second end is grounded and discharged through the solenoid valve control circuit 10;
[0062] A solenoid valve control circuit 10 connected to a first end of a second capacitor C2 and a positive electrode of a first power source VCC, and configured to provide a circuit for the first power source VCC to supply power to the solenoid valve 20 when a voltage of the second capacitor C2 is higher than a first threshold value;
[0063] A solenoid valve 20 connected to the solenoid valve control circuit 10 and configured to discharge condensed water when receiving power from a first power source VCC;
[0064] Wherein, the first switch tube Q1 and the second switch tube Q2 are both switched between the first end and the second end when the control end of the switch tube receives a high level signal.
[0065] Specifically, the specific device type of the trigger switch S1 can be selected according to actual needs, such as a common push-button single-pole double-throw switch. The first end of the trigger switch S1 is connected to the positive electrode of the first power supply VCC, and the second end is respectively connected to the anode of the first diode D1 and the control end of the first switch tube Q1. By operating the trigger switch S1, the user can control the first end of the trigger switch S1 and the second end of the trigger switch S1 to be in an on state or an off state.
[0066] The operation method of the trigger switch S1 of the present application is that when the user currently needs to discharge condensed water, the trigger switch S1 is turned on, and the trigger switch S1 is controlled to be turned off after a period of time. The period of time described here is usually a few seconds. In addition, even if the user forgets to control the trigger switch S1 to be turned off after turning on the trigger switch S1, the scheme of the present application will not cause the discharge of condensed water for too long. Continuous discharge of condensed water for too long may cause abnormal use. For example, when the condensed water discharge device of the present application is a condensed water discharge device in a device that uses drug vapor for treatment, if the condensed water is continuously discharged during use and is forgotten to be turned off, it will cause dilution of the drug components and reduce the treatment effect.
[0067] It can be seen from the circuit connection relationship that when the trigger switch S1 is turned on, the first power supply VCC can charge the first capacitor C1 through the trigger switch S1 and the first diode D1. 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 a few seconds, the trigger switch S1 can be turned off, and the first capacitor C1 can be discharged through the first resistor R1. At this time, the control end of the second switch tube Q2 is at a high level, so the first end of the second switch tube Q2 and the second end of the second switch tube Q2 are connected, so that the first power supply VCC can charge the second capacitor C2 through the second switch tube Q2 at this time, and the second capacitor C2 can be fully charged in a few seconds.
[0068] After the trigger switch S1 is turned off, the first capacitor C1 is discharged through the first resistor R1. When the voltage of the first capacitor C1 is not enough to turn on the second switch tube Q2, the second switch tube Q2 will be turned off. Usually, the first capacitor C1 can be discharged in a few seconds to more than ten seconds. 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 length of the discharge time of the first capacitor C1 will not have a significant impact on the solution, as long as the discharge time is not too long, because when the discharge time is too long and the second switch tube Q2 is turned on for a long time, it will cause the solenoid valve 20 to discharge condensed water for a long time.
[0069] When the second switch tube Q2 is turned on, the first power supply VCC can charge the second capacitor C2 through the second switch tube Q2. When the voltage of the second capacitor C2 is higher than the first threshold, the solenoid valve control circuit 10 can provide a circuit for the first power supply 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 supply VCC. After the second switch tube Q2 is turned off, the second capacitor C2 is continuously discharged through the solenoid valve control circuit 10. When the voltage of the second capacitor C2 is lower than the first threshold, the solenoid valve 20 cannot obtain power from the first power supply VCC, and the discharge of condensed water is stopped. It can be seen that the solution of the present application will not discharge condensed water for a long time.
[0070] Furthermore, even if the user makes an error operation and forgets to turn off the trigger switch S1, it will not cause the condensed water to be continuously discharged, that is, the solution of the present application has a protection function against malfunction. Specifically, it can be seen from the circuit structure that when the trigger switch S1 is turned on, the control end of the first switch tube Q1 is at a high level, and at this time, the first end of the first switch tube Q1 and the second end of the first switch tube Q1 are connected, so that the control end of the second switch tube Q2 is at a low level, that is, the second switch tube Q2 cannot be turned on, so the second capacitor C2 will not be charged, and the solenoid valve 20 will not be able to discharge the condensed water.
[0071] The present application defines the discharge loop of the first capacitor C1 by the first diode D1 and the second diode D2. Specifically, if the first diode D1 is not provided, the first capacitor C1 will discharge in two directions, so that the first switch tube Q1 is turned on, and then the second switch tube Q2 cannot be turned on, and the scheme cannot discharge condensed water. The second switch tube Q2 can avoid the current backflow caused by the damage of the second switch tube Q2 and other reasons, which may cause dangerous situations.
[0072] In the solution of the present application, the first switch tube Q1, the second switch tube Q2 and the third switch tube Q3 described later are all connected between the first end and the second end when the control end receives a high-level signal. The specific device type used can be set and selected according to actual needs. For example, NPN-type transistors, MOS transistors and other devices can be selected as long as they meet the requirements of the present application. In each of the drawings of the present application, low-cost NPN-type transistors are used.
[0073] In a specific embodiment of the present invention, please refer to Figure 2 , and may also include:
[0074] A second resistor R2 having a first end connected to the cathode of the second diode D2 and a second end respectively connected to the control end of the second switch tube Q2 and the first end of the first switch tube Q1;
[0075] A third resistor R3 whose first end is connected to the second end of the trigger switch S1 and whose second end is connected to the control end of the first switch tube Q1;
[0076] A fourth resistor R4 has a first end connected to the second end of the trigger switch S1 and a second end connected to the ground.
[0077] Considering that the tolerable current of the first switch tube Q1 and the second switch tube Q2 is relatively low, in this implementation, current limiting is performed by the second resistor R2 and the third resistor R3, which is beneficial to ensure the safe operation of the first switch tube Q1 and the second switch tube Q2.
[0078] The fourth resistor R4 can provide a static operating point for the first switch tube Q1 to ensure reliable shutdown of the first switch tube Q1.
[0079] The specific circuit structure of the solenoid valve control circuit 10 can be set according to actual needs. It only needs to provide a discharge circuit for the second capacitor C2, and provide a circuit for the first power supply VCC to supply power to the solenoid valve 20 when the voltage of the second capacitor C2 is higher than the first threshold. For example, in a specific embodiment of the present invention, please refer to Figure 3 , the solenoid valve control circuit 10 comprises:
[0080] The first control end is connected to the positive electrode of the first power supply VCC, the second control end is connected to the first end of the third switch tube Q3, the first controlled end is connected to the positive electrode of the first power supply VCC, and the second controlled end is connected to the positive electrode of the drain of the solenoid valve 20 of the relay K1;
[0081] A third switch tube Q3 having a control end connected to a first end of the second capacitor C2 and a second end connected to a negative electrode of the drain of the electromagnetic valve 20 and grounded;
[0082] When the control end of the third switch tube Q3 receives a high level signal, the first end and the second end of the third switch tube Q3 are conductively connected.
[0083] In this implementation, the solenoid valve control circuit 10 is composed of only one relay K1 and the third switch tube Q3, and the circuit structure is simple and the reliability is high.
[0084] Specifically, it can be seen from the circuit structure that when the voltage of the second capacitor C2 is higher than the first threshold value, the third switch tube Q3 will be turned on, that is, the first end and the second end of the third switch tube Q3 are turned on, and the relay K1 will be attracted, so that the first controlled end and the second controlled end of the relay K1 are turned on, and the first power supply VCC can supply power to the solenoid valve 20 through the relay K1, specifically, to the drainer of the solenoid valve 20, so that the drainer of the solenoid valve 20 discharges condensed water.
[0085] After the second switch tube Q2 is turned off, as the second capacitor C2 discharges, when the second capacitor C2 discharges to a voltage lower than the first threshold, the third switch tube Q3 is turned off, so that the relay K1 is turned off, and the solenoid valve 20 stops discharging condensed water. The first threshold depends on the conduction voltage of the third switch tube Q3.
[0086] The discharge time of the second capacitor C2 will affect the discharge time of the condensed water. Therefore, in order to more conveniently control the discharge time of the second capacitor C2, that is, to control the discharge time of the condensed water, in a specific embodiment of the present invention, reference may be made to Figure 4 , and may also include:
[0087] A variable resistor RX having a first end connected to a first end of the second capacitor C2 and a second end connected to a control end of the third switch tube Q3.
[0088] The resistance value of the variable resistor RX can be easily adjusted. By adjusting the resistance value of the variable resistor RX, the discharge time of the second capacitor C2 can be adjusted, thereby changing the discharge time of the condensed water, thereby greatly improving the flexibility of the solution.
[0089] In a specific embodiment of the present invention, please refer to Figure 4 , and may also include:
[0090] A fifth resistor R5 whose first end is connected to the positive electrode of the first power source VCC and whose second end is respectively connected to the first end of the sixth resistor R6 and the first end of the third capacitor C3;
[0091] A third capacitor C3 having a second terminal grounded;
[0092] A sixth resistor R6 having a second end connected to the control end of the fourth switch tube Q4;
[0093] A fourth switch tube Q4 having a first end connected to the positive electrode of the first power source VCC and a second end connected to the first end of the second capacitor C2;
[0094] When the control end of the fourth switch tube Q4 receives a low level signal, the first end and the second end of the fourth switch tube Q4 are conductively connected.
[0095] In this implementation, it is considered that in actual use, it is usually necessary to discharge condensed water once when the device is powered on, that is, to discharge the condensed water remaining during the previous use. However, the user may not remember to do this every time when using it. Therefore, in this implementation, the discharge of condensed water can be automatically triggered every time the device is powered on.
[0096] Specifically, it can be seen from the circuit structure that after power-on, since the voltage across the third capacitor C3 cannot change suddenly, the control end of the fourth switch tube Q4 is a low-level signal. At this time, the first end and the second end of the fourth switch tube Q4 are connected, and the first power supply VCC can charge the second capacitor C2 through the fourth switch tube Q4, thereby realizing the discharge of condensed water. As the third capacitor C3 is charged, the voltage of the third capacitor C3 rises, and the fourth switch tube Q4 will be turned off. The fourth switch tube Q4 can use PNP-type transistors, MOS tubes and other devices, as long as they can achieve the purpose of this application.
[0097] Furthermore, in a specific embodiment of the present invention, it may also include:
[0098] A third diode D3 has a cathode connected to the first control end of the relay K1 and an anode connected to the second control end of the relay K1.
[0099] This is because the relay K1 is a magnetic component and will generate an induced electromotive force after power failure. Therefore, a third diode D3 is added in this embodiment to form a discharge circuit for the induced electromotive force, which is beneficial to the protection of circuit components.
[0100] Similarly, the solenoid valve 20 is also a magnetic component, and therefore may also include:
[0101] A fourth diode D4 whose cathode is connected to the positive electrode of the drain of the solenoid valve 20 and whose anode is connected to the negative electrode of the drain of the solenoid valve 20 forms a discharge loop through the fourth diode D4 to protect the circuit. In addition, the specific structure of the drain of the solenoid valve 20 is not shown in the drawings of the present application, and can be set according to actual needs without affecting the implementation of the present invention.
[0102] In addition, in a specific embodiment of the present invention, it may also include:
[0103] A display circuit connected to the positive electrode of the first power source VCC and configured to display after receiving power from the first power source VCC.
[0104] Since the display circuit is connected to the positive electrode of the first power supply VCC, the display circuit can display whether the power is normally on, that is, whether the first power supply VCC has power. The voltage level of the first power supply VCC can also be set and adjusted according to actual needs, for example, it can be 12V.
[0105] exist Figure 4 In the implementation manner, the display circuit specifically includes:
[0106] A seventh resistor R7 having a first end connected to the positive electrode of the first power supply VCC and a second end connected to the anode of the light emitting diode D5;
[0107] The cathode of the light emitting diode D5 is grounded.
[0108] The display circuit in this embodiment is composed of a seventh resistor R7 and a light emitting diode D5, and has a simple circuit structure and high reliability. The user can determine whether the first power supply VCC has power by observing whether the light emitting diode D5 is on.
[0109] In the scheme of the present application, the discharge control of condensed water is realized by triggering switch S1, first diode D1, first capacitor C1, first resistor R1, second diode D2, first switch tube Q1, second switch tube Q2, second capacitor C2, solenoid valve control circuit 10 and solenoid valve 20. Basic components are selected, and the circuit structure is simple and easy to implement. There is no need to use a single-chip microcomputer or clock chip to realize control as in the traditional scheme. Therefore, the scheme of the present application is relatively low in cost. In addition, the condensed water discharge device of the present application also has a protection function against malfunction, and abnormal situations caused by discharging condensed water for too long will not occur. Specifically, the user needs to operate the trigger switch S1 to close, and then disconnect the trigger switch S1, and the condensed water discharge device of the present application can discharge condensed water. When the trigger switch S1 is closed, the first capacitor C1 is charged. After the trigger switch S1 is disconnected, the first capacitor C1 is discharged through the first resistor R1. The control end of the second switch tube Q2 is at a high level, so that the first end of the second switch tube Q2 and the second end of the second switch tube Q2 are connected. The second capacitor C2 can be charged by the first power supply VCC, so that the voltage of the second capacitor C2 is higher than the first threshold value, and the solenoid valve control circuit 10 can provide a circuit for the first power supply VCC to supply power to the solenoid valve 20. When the solenoid valve 20 receives the power supply of the first power supply VCC, it can discharge condensed water. After the first capacitor C1 is discharged, the control end of the second switch tube Q2 is at a low level, so that the second switch tube Q2 is turned off. The second capacitor C2 is discharged through the solenoid valve control circuit 10. When the voltage is lower than the first threshold value, the solenoid valve 20 no longer discharges condensed water. It can be seen that in normal use, the solution of the present application realizes the discharge of condensed water, and there will be no continuous discharge. Furthermore, in the solution of the present application, even if the user forgets to disconnect the trigger switch S1 after the user operates the trigger switch S1 to close, the solenoid valve 20 will not cause the continuous discharge of condensed water. This is because after the user operates the trigger switch S1 to close, even if the user forgets to turn it off, since the first switch tube Q1 is turned on at this time, and when the first switch tube Q1 is turned on, the control end of the second switch tube Q2 is grounded, so the second capacitor C2 cannot be charged by the first power supply VCC, which plays a role in avoiding misoperation. In summary, the solution of the present application can effectively realize the discharge of condensed water, with low cost, and has protection against misoperation, and the solenoid valve 20 will not cause continuous discharge of condensed water due to user misoperation.
