本发明涉及空气净化器领域，更具体的说是涉及一种空气净化智能控制器电路。The invention relates to the field of air purifiers, in particular to an air purifying intelligent controller circuit.
背景技术Background technique
现在医院病房的封闭环境中，往往会出现空气质量不佳的问题，这样就需要一些空气净化器和智能控制器对病房的空气进行净化。Now in the closed environment of hospital wards, the problem of poor air quality often occurs, so some air purifiers and intelligent controllers are needed to purify the air in the wards.
而市面上行的空气净化器价格和成本较高，这样医院统一购置就会需要大量的资金成本，这样通过厂家在医院免费提供空气净化器，然后通过病患或者其家属通过手机对智能控制器通信，其中智能控制器集成在空气净化器中，通过手机付款之后，即可对空气净化器进行租用，这种共享的模式在市面上越来越普遍，也逐渐流行起来，而市面上暂时没有共享模式的空气净化器，并且普及难度也较高，医院中也尚未普及，这样在医院中普及空气净化器可以减少空气中的病菌以及灰尘，可以减少对病患的健康产生影响。However, the price and cost of air purifiers on the market are relatively high, so that hospitals will need a lot of capital costs for unified purchase. In this way, manufacturers provide air purifiers for free in hospitals, and then patients or their family members communicate with the smart controller through mobile phones. , in which the smart controller is integrated in the air purifier, and the air purifier can be rented after payment through the mobile phone. This sharing mode is becoming more and more common in the market, and it is gradually becoming popular, but there is no sharing mode in the market for the time being. It is difficult to popularize air purifiers, and it has not yet been popularized in hospitals. In this way, the popularization of air purifiers in hospitals can reduce germs and dust in the air, and can reduce the impact on patients' health.

通过上述技术方案，当用户需要对电源进行开关时，可以先将外部空气净化器的接插头32插入到外部的插座内，这样来获取外部的220V交流电，220V交流电经过保护电路3后进入到开关电路2，通过保护电路3的保护作用，可以减少外部插座内电源的电源波动对空气净化器产生的影响，用户在通过手机与控制电路1进行通信，通过手机发送租用信号给主控电路，主控电路接收到租用信号后发送控制信号给开关电路2，开关电路2根据控制电路1发送的控制信号执行对应的动作，例如，控制电路1发送“1”为连通的控制信号，则开关电路2接收到该信号后打开电源输出，这样就可以将220V交流电连通，经过开关电路2后进行输出，控制电路1发送“0”为断开的控制信号，则开关电路2接收到该信号后断开电源输出，这样就可以将220V的交流电断开，这样开关电路2就不会输出电源，这样就可以实现用户通过自己的手机来远程租用空气净化器，通过远程的方式用户可以完全不触碰空气净化器的开关，通过主控芯片11的小电压的弱点控制信号对220V的交流电源进行控制，这样就大大增加了安全性，就不需要用开关按钮直接对220V的交流电进行开关，避免了用户手心有汗或者刚洗过手等手部较潮湿的情况下按压开关按钮产生电火花后对人体造成伤害的安全隐患，就具有更高的智能化操作，接插头32与开关电路2之间连接了热敏电阻31，这里热敏电阻31可以采用敏感度较高的正温系数的PTC电阻，这样当接插头32接收到的外部220V交流电源后，如果改220V交流电源产生波动，如果在短时间内一直处于过压的状态，则该热敏电阻31的温度就会增高，并且其电阻值随着温度的升高而大幅度增大，这样就可以大幅度的减小接插头32与开关电路2之间的电流，其阻值增大后相当于将接插头32与开关电路2断路，这样就可以保护后续的电路，可以避免空气净化器内的元器件损坏，这样就可以延长空气净化器的寿命，当用户需要对开关电路2进行操作时，用户就可以通过控制电路1发送控制信号给线圈21，然后线圈21接收到控制信号就可以实现通电或者断电，这样当线圈21通电后就会产生磁场，通过磁场具有的磁性就可以将吸引弹片22，将弹片22与触点23吸合，这样就可以将弹片22与触点23导通，这样就可以将外部的220V交流电源经过弹片22后经过触点23，这样就可以进入到空气净化器中，对空气净化器进行供电，这样就可以实现小电流控制大电流的开关，这样就避免了直接对220V交流电源进行控制，这样大大增加了用户操作过程的安全性，当用户需要对控制电路1进行操作时，这里的通信芯片41可以选用M6312，这样用户可以通过手机与通信芯片41进行通信连接，然后手机就可以发送租用信号给主控芯片11，主控芯片11就可以通过选择开启或者关断的控制信号进行发送，这样主控芯片11就可以发送控制信号给电阻R3，这样电阻R3就可以将该信号的电流缩小，然后在将该信号发送给三极管Q1的基极，如果该信号是开启的控制信号，则三极管Q1的集电极与发射极导通，这样线圈21的一端接电源另一端接集电极，当集电极与和发射极导通时，线圈21接集电极的一端就会接地，这样就线圈21上就可以通电，就可以产生磁场，进而完成开关，这样就用户就不需要直接触摸控制电路1来完成操作，通过手机来控制可以完全避开对电路的直接操作，这样可以大大增加安全性，当线圈21处于通电状态下时进行断开，这样线圈21上就会产生反向电动势，这样就会产生瞬间的高压，这样容易导致三极管Q1击穿和烧损，这样就会损坏元器件，缩短使用寿命，设置了二极管之后，当线圈21产生方向电动势，电流就可以经过二极管的正极之后，从二极管的负极流出，这样二极管与线圈21就形成一个回路，这样就不会产生瞬间的高压，进而对电路进行保护，延长空气净化器的使用寿命，通过这种共享模式，就方便厂家直接免费对医院进行普及，这样就可以实现医院与厂家共赢，厂家为医院免费提供空气净化器，而病人通过手机可以进行付款，然后进行租用，这样就方便了空气净化器的普及，医院不需要成本，将成本交给厂家自己来出，而租用的费用用户来支付。Through the above technical solution, when the user needs to switch the power supply, the plug 32 of the external air purifier can be inserted into the external socket first, so as to obtain the external 220V alternating current, and the 220V alternating current enters the switch after passing through the protection circuit 3 Circuit 2, through the protection function of the protection circuit 3, can reduce the impact of the power fluctuation of the power supply in the external socket on the air purifier. The user communicates with the control circuit 1 through the mobile phone, and sends a rental signal to the main control circuit through the mobile phone. The control circuit sends a control signal to the switch circuit 2 after receiving the rental signal, and the switch circuit 2 performs corresponding actions according to the control signal sent by the control circuit 1. After receiving the signal, turn on the power output, so that the 220V AC can be connected and output after passing through the switch circuit 2. The control circuit 1 sends "0" as a control signal for disconnection, and the switch circuit 2 disconnects after receiving the signal. Power output, so that the 220V AC power can be disconnected, so that the switch circuit 2 will not output power, so that the user can rent the air purifier remotely through his mobile phone, and the user can not touch the air at all through the remote method The switch of the purifier controls the 220V AC power supply through the weak point control signal of the main control chip 11, which greatly increases the safety, and does not need to use the switch button to directly switch the 220V AC power, avoiding the user When the palms are sweaty or the hands are wet after washing or just washing hands, pressing the switch button will cause potential safety hazards to the human body after electric sparks are generated, so it has a higher intelligent operation. Thermistor 31, where the thermistor 31 can adopt a PTC resistor with a higher positive temperature coefficient of sensitivity, so that after the external 220V AC power supply is received by the plug 32, if the 220V AC power supply fluctuates, if in a short time If the inside is always in an overvoltage state, the temperature of the thermistor 31 will increase, and its resistance value will increase significantly with the increase of temperature, so that the connection between the plug 32 and the switch circuit can be greatly reduced. 2, the resistance value increases, which is equivalent to disconnecting the plug 32 from the switch circuit 2, so that the subsequent circuit can be protected, and the components in the air purifier can be avoided from being damaged, so that the air purifier can be extended. When the user needs to operate the switch circuit 2, the user can send a control signal to the coil 21 through the control circuit 1, and then the coil 21 can be powered on or off after receiving the control signal, so that when the coil 21 is powered on A magnetic field will be generated, and the magnetism of the magnetic field can attract the shrapnel 22 and attract the shrapnel 22 to the contact 23, so that the shrapnel 22 and the contact 23 can be conducted, so that the external 220V AC power supply can be passed through the shrapnel After 22, it passes through the contact 23, so that it can enter the air purifier and supply power to the air purifier, so that a small current can control a large current switch, so that It avoids directly controlling the 220V AC power supply, which greatly increases the safety of the user's operation process. When the user needs to operate the control circuit 1, the communication chip 41 here can be M6312, so that the user can communicate with the communication chip 41 through the mobile phone. Carry out a communication connection, and then the mobile phone can send a rental signal to the main control chip 11, and the main control chip 11 can send the control signal by selecting on or off, so that the main control chip 11 can send the control signal to the resistor R3, so that The resistor R3 can reduce the current of the signal, and then send the signal to the base of the transistor Q1. If the signal is a control signal for turning on, the collector and the emitter of the transistor Q1 are turned on, so that one end of the coil 21 The other end of the power supply is connected to the collector. When the collector is connected to the emitter, the end of the coil 21 connected to the collector will be grounded, so that the coil 21 can be energized to generate a magnetic field, and then complete the switch.
