The following description will be made in conjunction with the accompanying drawings, and an embodiment of an atomization humidification system, a control method and a device provided by the embodiments of the present invention is described below.
According to the technical scheme provided by the embodiment of the invention, whether the float valve is closed or is about to be closed is judged according to the current value of the liquid pump during working so as to control the opening or closing of the liquid pump and the electromagnetic valve and prevent the float valve from being in a working state for a long time.
An atomization humidification system provided by an embodiment of the present invention is shown in fig. 1, and includes: the device comprises an ultrasonic atomizer 1, a fan 2, a mist outlet 3, a liquid pump 4, an electromagnetic valve 5, a ball float valve 6, a controller 7 and a liquid tank 8;
the ultrasonic atomizer 1 comprises at least one atomizing head 10, the atomizing head 10 breaks up molecular bonds among liquid molecules through high-frequency resonance to generate naturally flowing water mist, the fan 2 is used for blowing air into the liquid tank 8, the water mist generated by the atomizing head 10 is blown to the mist outlet 3, the air is fed into the mist conveying pipeline 11 through the mist outlet 3 and is sprayed out from the mist outlet 12, and the baffle plate 9 is used for preventing the blown air from flowing in the liquid tank 8 in a rotating mode to cause mist quantity loss; the ultrasonic atomizer 1 can be more than one, for example, a plurality of ultrasonic atomizers with single atomizing heads can be used, so that the damaged ultrasonic atomizers can be replaced conveniently, and even if one of the ultrasonic atomizers is damaged, the fog can not be influenced, but the fog outlet amount is small; the liquid pump 4 is used for conveying liquid to the liquid tank 8, the electromagnetic valve 5 is used for switching on and off a pipeline, and the ball float valve 6 is used for automatically switching on and off the pipeline so as to control the height of the liquid level in the liquid tank 8; the liquid pump 4 is connected with the electromagnetic valve 5 through a pipeline, the electromagnetic valve 5 is connected with the float valve 6 through a pipeline, liquid conveyed by the liquid pump 4 can reach the float valve 6 only by opening the electromagnetic valve 5, the float valve 6 is installed on the liquid tank 8 and used for limiting the liquid level height to reach the optimal liquid level height of the ultrasonic atomizer 1, and when the liquid level is higher than the limited liquid level height, the float valve 6 is automatically closed under the action of buoyancy to prevent the liquid from continuously injecting into the liquid tank 8 to cause the liquid to overflow;
the controller 7 is connected with the ultrasonic atomizer 1, the fan 2, the liquid pump 4 and the electromagnetic valve 5 and is used for controlling the ultrasonic atomizer 1 to generate water mist and controlling the fan 2 to send the water mist into the mist conveying pipeline 11; the liquid pump 4 and the electromagnetic valve 5 are started at preset time intervals, for example, the liquid level height can be controlled in a reasonable interval at preset proper time intervals, such as every 1 minute, every 10 minutes, every 30 minutes and the like, according to the mist quantity generated by ultrasonic waves, the liquid pump 4 and the electromagnetic valve 5 are not required to be started and stopped frequently, a ball float valve is not required to be opened and closed frequently, the working strength is reduced, and the service life is prolonged;
the controller 7 is configured to detect a magnitude relationship between a first current value of the liquid pump 4 and a first preset threshold and a second preset threshold that are sequentially increased, where the first preset threshold may be a current value corresponding to a fully open state of the float valve, and the second preset threshold may be a current value corresponding to a partially open state of the float valve or a fully closed state of the float valve; if the first current value is smaller than the first preset threshold value, continuing to open the liquid pump 4 and the electromagnetic valve 5, and injecting liquid into the liquid tank 8; and if the first current value is greater than the second preset threshold value, closing the liquid pump 4 and the electromagnetic valve 5, and stopping injecting the liquid into the liquid tank 8 so as to keep the liquid level height.
Optionally, the controller 7 is further configured to detect a third current value of the ultrasonic atomizer, and when the third current value is smaller than a third preset threshold, open the liquid pump and the electromagnetic valve; at present, most of ultrasonic atomizers have a liquid shortage protection function, when the liquid level is lower than the protection height of the ultrasonic atomizer 1, the ultrasonic atomizer stops working, and then the current value of the ultrasonic atomizer obtained by a controller is much smaller than that of the ultrasonic atomizer in normal working; in addition, when the liquid is reduced to make part of the atomizing head 10 have no liquid, the current of the whole ultrasonic atomizer is reduced; wherein, the third threshold value of predetermineeing does current value when ultrasonic nebulizer 1 normally works, detects the third current value is less than when the third threshold value of predetermineeing, explains that ultrasonic nebulizer 1 does not normally work, and probably the liquid level highly is less than ultrasonic nebulizer 1's minimum liquid level height, because of lacking liquid and stop work, or highly different that place at a plurality of ultrasonic nebulizer, the ultrasonic nebulizer who is in the high position because of lacking liquid stop work earlier, controller 7 just can judge that lack liquid in the liquid case 8 has, so can control to open liquid pump 4 with solenoid valve 5 adds the liquid to liquid case 8 in, and the operating current of using ultrasonic nebulizer is as low liquid level sensing signal, has simplified the system, has protected the atomising head, has increased system reliability.
Optionally, when the ultrasonic atomizer 4 has a fault, for example, one of the atomizing heads is broken, the detected third current value will be always smaller than the third preset threshold, so that, when the system cannot judge whether the third current value caused by liquid shortage or ultrasonic atomizer fault is smaller than the third preset threshold, the controller 7 may judge that the ultrasonic atomizer has a fault by the current value of the liquid pump, that is, when the detected first current value is greater than the second preset threshold, the liquid level reaches the set height, and at this time, if the detected third current value is still smaller than the third preset threshold, the controller 7 may judge that the ultrasonic atomizer has a fault and generate an ultrasonic atomizer fault alarm instruction, where the ultrasonic atomizer alarm instruction is used to trigger an alarm device, such as but not limited to a speaker, a display, a signal lamp, and the like, but not limited to a speaker, a display, and a signal lamp, and may also send an alarm signal to the mobile terminal by the wireless module, so as to remind the user of repairing the ultrasonic atomizer in time.
Optionally, in practical application, a user needs to adjust the mist output, for example, the voltage input to the ultrasonic atomizer is adjusted by PWM chopping to adjust the power, that is, the height of the ultrasonic atomizer and the liquid level is normal, but the detected third current value is smaller than the third preset threshold, so that the third current value detected after the power is adjusted cannot be used as a basis for judging the fault of the liquid level and the ultrasonic atomizer; then, the controller 7 is configured to control the ultrasonic atomizer 1 to operate at the rated power for a predetermined time and obtain the third current value of the ultrasonic atomizer 1 when the third current value of the ultrasonic atomizer 1 needs to be obtained, for example, when the controller needs to detect the third current value, the controller controls the ultrasonic atomizer to operate at the rated power for 30ms (of course, other predetermined times are also possible), and the detection of the third current value is completed within 30ms, because the operation time of the ultrasonic atomizer at the rated power is very short, and there is no influence on the fog output.
Optionally, the controller 7 is further configured to generate a liquid shortage alarm instruction when it is detected that the first current value is smaller than the first preset threshold value and reaches a preset time, where the liquid shortage alarm instruction is used to trigger an alarm device and close the liquid pump and the electromagnetic valve; for example, the liquid pump 4 and the electromagnetic valve 5 are started for 2 minutes, the detected first current value is smaller than a first preset threshold value, the controller 7 may determine that the amount of inlet water is insufficient, close the liquid pump 4 and the electromagnetic valve 5, and generate a liquid shortage alarm instruction to trigger an alarm device to remind a user of checking;
in addition, when the first current value is detected to be larger than the first preset threshold value and smaller than the second preset threshold value and reach preset time, a ball float valve fault alarm instruction is generated, and the ball float valve fault alarm instruction is used for triggering an alarm device and closing the liquid pump and the electromagnetic valve; for example, when the liquid pump and the electromagnetic valve are started for 2 minutes, and the detected first current value is greater than the first preset threshold value and less than the second preset threshold value, generally because the float valve leaks, if the flow area inside the float valve is less than the flow area when the float valve is fully opened but greater than the flow area when the float valve is partially opened or fully closed, liquid still can pass through the float valve, even if the liquid level is higher than the turn-off height of the float valve, if liquid is continuously added, the liquid level may overflow, so the liquid pump and the electromagnetic valve need to be closed, liquid adding is stopped, and a float valve fault alarm instruction is generated to trigger an alarm device to remind a user of maintenance.
Optionally, as shown in fig. 2, in practical applications, a suitable liquid level interval may be set by a liquid level sensor, and therefore the system further includes a first liquid level sensor 13, where the first liquid level sensor 13 is configured to detect a liquid level height, where the detected liquid level height is a lowest liquid level of an optimal operating liquid level interval of the ultrasonic nebulizer 1, and therefore, the controller 7 is configured to obtain the liquid level height detected by the first liquid level sensor 13;
when the liquid level is detected to be lower than the liquid level height detected by the first liquid level sensor 13, the liquid pump and the electromagnetic valve are started, and liquid is injected into the liquid tank; and when the first current value of the hydraulic pump is detected to be larger than the second preset threshold value, closing the hydraulic pump and the electromagnetic valve to complete liquid adding, so that the ultrasonic atomizer works in an optimal liquid interval.
In summary, the liquid level height of the liquid tank is maintained by using the combined control of the liquid pump, the electromagnetic valve and the ball float valve, the volume of the atomization humidification system is greatly reduced, a user can select a proper liquid storage container (such as a bucket with various volumes) according to actual needs, a non-pressure water source (such as barreled water) and a pressure water source (such as tap water and full-house purified water) can be used, and the opening or closing of the liquid pump and the electromagnetic valve is controlled by the corresponding relation between the current value of the liquid pump and the state of the ball float valve, so that the automatic liquid supplement is realized; liquid pump and solenoid valve are closed back ball-cock assembly and the pipeline disconnection, need not to bear liquid source pressure, increase the ball-cock assembly life-span, block the pipeline through solenoid valve and ball-cock assembly and prevent that the liquid pump from overflowing the liquid that causes out of control, stop the liquid and spill over the condition, judge whether the liquid source lacks the liquid through detecting the liquid pump current value, judge whether the liquid case lacks liquid or the ultrasonic atomization ware trouble through the operating current that detects the ultrasonic atomization ware, carry out real time monitoring to whole atomizing humidification system state, ensure that the system is stable and high-efficient.
As shown in fig. 3, a control method of an atomization humidification system according to an embodiment of the present invention includes:
s101, opening a liquid pump and an electromagnetic valve at preset time intervals to obtain a current value of the liquid pump;
specifically, the ultrasonic atomizer has an optimal working liquid level interval, and the flow consumption is slow, so that the liquid pump and the electromagnetic valve can be intermittently started to feed liquid to the liquid tank, and the current value of the liquid pump can be obtained.
S102, detecting the magnitude relation between a first current value of the liquid pump and a first preset threshold and a second preset threshold which are increased in sequence;
specifically, since the float of the float valve changes the internal flow area along with the rise of the liquid level, when the flow area changes, the pressure of the liquid also changes, so that the current value of the liquid pump also changes, therefore, the first preset threshold may be a current value corresponding to a fully open state of the float valve, and the second preset threshold may be a current value corresponding to a partially open state of the float valve or a current value corresponding to a fully closed state.
S103, if the first current value is smaller than the first preset threshold value, continuing to start the liquid pump and the electromagnetic valve; and if the first current value is larger than the second preset threshold value, closing the liquid pump and the electromagnetic valve.
