The heating cavity 21 is internally provided with a heating element 22, wherein the heating element 22 can be a PTC heating tube, and the heating tube can heat water in the heating cavity 21, so that the temperature of the water in the heating cavity 21 rises, water vapor is generated after the water in the heating cavity 21 is vaporized, the heating cavity 21 is provided with a vapor outlet 23, and the vapor in the heating cavity 21 is discharged from the vapor outlet 23, thereby realizing the purpose of humidification.

The temperature sensor 24 can detect the temperature in the heating chamber 21 in real time, and the humidity sensor can detect the temperature of the current environment in real time.
In addition, both the humidity sensor and the temperature sensor 24 are communicatively connected to the electromagnetic pump 4.

As shown in fig. 3, a control method of the humidifying device 10 according to an embodiment of the present invention includes:
S1: starting the humidifying device 10, starting the humidifying device 10 to operate, and starting the heating element 22 in the heating cavity 21 to work, so that the water temperature in the heating cavity 21 is slowly increased; when the heating element 22 is a PTC heating tube, the PTC heating tube may be controlled by a PTC relay, and when the humidifying device 10 starts to operate, the PTC relay is turned on, and the PTC heating tube is started to operate.
S2: acquiring the temperature of the heating cavity 21; the temperature of the heating chamber 21 may be obtained by the temperature sensor 24, and the temperature sensor 24 may obtain the temperature of the heating chamber 21 in real time.
S3: when the temperature of the heating cavity 21 reaches the set temperature, water is added into the heating cavity 21; it can be understood that the temperature of the heating cavity 21 is lower, the water entering the heating cavity 21 is not easily gasified, so that the water vapor is not easily generated in the heating cavity 21, the humidifying effect is poor, the temperature of the heating cavity 21 is higher, the water entering the heating cavity 21 is easily gasified, so that the water vapor is easily generated in the heating cavity 21, the amount of the generated water vapor is larger, and the humidifying effect is good. In the invention, the set temperature can better heat water to generate water vapor, thereby ensuring the humidifying effect, and avoiding cold water from entering the heating cavity 21 when the temperature of the heating cavity 21 does not reach the set temperature, so that the temperature of the heating cavity 21 is further reduced, and the humidifying effect is reduced.
Specifically, when the temperature in the heating chamber 21 reaches the set temperature, water in the water tank 1 is added into the heating chamber 21 by the electromagnetic pump 4, and the water entering the heating chamber 21 is heated by the heating member 22 in the heating chamber 21, so that a large amount of water vapor is generated, and the water vapor is discharged from the vapor outlet 23, thereby realizing humidification of the environment in which the humidifying device 10 is located.
S4: when the current ambient humidity satisfies the preset condition, the humidifying device 10 is turned off. The preset condition is an environmental humidity that the user feels comfortable, specifically, the preset condition may be a target humidity set by the user, that is, when the current environmental humidity reaches the target humidity, the humidifying device 10 is turned off, and of course, the preset condition may also be a comfortable environmental humidity value corresponding to the current environment, and when the current environmental humidity reaches a comfortable temperature corresponding to the current environmental temperature, the humidifying device 10 may be turned off. The humidity corresponding to the current ambient temperature may be a humidity value or a humidity interval. When the humidity corresponding to the current ambient temperature is a humidity interval, the humidifying device 10 may be turned off when the current ambient humidity is in the humidity interval.
According to the control method of the humidifying device 10 in the embodiment of the invention, the temperature of the heating cavity 21 is obtained, and when the temperature of the heating cavity 21 reaches the set temperature, water is added into the heating cavity 21, so that the temperature in the heating cavity 21 is not too low, the heating effect of water in the heating cavity 21 is ensured, the efficiency of generating water vapor is further ensured, and the humidifying effect is ensured.
As shown in fig. 4, in some embodiments of the present invention, the control method further includes:
a1: acquiring the current environmental humidity; in the present invention, a humidity sensor may be provided on the humidifying device 10, and the humidity sensor may acquire the current ambient humidity of the environment in which the humidifying device 10 is located.
A2: the operation mode of the humidifying device 10 is determined according to the target humidity and the current ambient humidity, and includes at least one of an enhanced mode, a normal mode, and an energy saving mode. It will be appreciated that the humidification mode of the humidification apparatus 10 has three modes of energy saving, enhancement and normal, and the specific humidification mode of the humidification apparatus 10 can be determined according to the difference between the target humidity that the user wants to achieve and the current ambient humidity measured by the temperature sensor 24, for example, when the difference between the target humidity and the current ambient humidity that the user wants to achieve is large, it is indicated that the current ambient humidity is low at this time, and the enhancement mode can be adopted for rapid humidification; when the difference between the target humidity which the user wants to reach and the current environment humidity is moderate, a common mode can be adopted, so that the humidification requirement can be met, and the energy-saving requirement can be met to a certain extent; when the difference between the target humidity which the user wants to reach and the current environment humidity is smaller, an energy-saving mode can be adopted, and the energy-saving requirement is met to the greatest extent on the premise of meeting the humidifying requirement.
In addition, the enhancement mode may be used in an initial stage of the opening of the humidifying device 10, the difference between the target humidity and the current ambient humidity is larger, rapid humidification may be performed, the normal mode may be used in a middle stage of the opening of the humidifying device 10, the difference between the target humidity and the current ambient humidity is moderate, stable humidification may be performed, the energy-saving mode may be used in an end stage of the opening of the humidifying device 10, the difference between the target humidity and the current ambient humidity measured by the temperature sensor 24 is smaller, and the current ambient humidity is very close to the target humidity and is mainly used for reducing the intensity of humidification.
For example, after the humidifying device 10 is turned on, the enhancement mode is adopted in the initial stage, the normal mode is adopted in the middle stage, the energy-saving mode is adopted in the final stage, or the normal mode is adopted in the early stage after the humidifying device 10 is turned on, or the energy-saving mode is adopted in the later stage after the humidifying device 10 is turned on, or the enhancement mode is adopted in the early stage and the normal mode is adopted in the later stage. In this application, multiple humidification modes can be combined, can adjust humidification intensity of humidification device 10, satisfy user's user demand, and satisfy energy-conserving requirement to the maximum extent.
In the related art, a common control method for steam humidification is to control a water pump or an electromagnetic pump by a relay, and control the humidification amount by the on/off time of the relay. This mode has a drawback, when the heating cavity is very hot under the condition, opens the relay suddenly and lets the water pump start, and when low temperature water was got into the heating cavity fast, partly incompletely vaporization liquid, received the effect of internal pressure and can be by quick blowout heating cavity, caused the risk of high temperature liquid from the drip of air conditioner wind channel. Meanwhile, the control method can not adjust the humidifying intensity and can only operate in one humidifying gear.
The humidifying device 10 of the present application can operate in three humidification modes, thereby satisfying the use requirements of users.
Further, when the temperature of the heating chamber 21 reaches the set temperature, water is added to the heating chamber 21, further comprising:
when the temperature of the heating chamber 21 reaches the set temperature, water is added to the heating chamber 21 according to the operation mode. The humidification intensity of the enhancement mode is larger than that of the normal mode, the humidification intensity of the normal mode is larger than that of the energy-saving mode, different amounts of water can be added into the heating cavity 21 according to the different humidification intensities when water is added into the heating cavity 21, or the speed of the water is different, or the set temperature when water is added into the heating cavity 21 is different, so that the water can be added into the heating cavity 21 according to the different operation modes such as the enhancement mode, the normal mode and the energy-saving mode, and the humidification requirements of the different humidification modes can be better met, and the energy-saving requirement can be met as much as possible on the premise of meeting the humidification requirements.

In other embodiments of the present invention, the control method of the humidifying device 10 further includes:
the humidifying device 10 is controlled to operate in the enhanced mode before the current ambient humidity is acquired. It will be appreciated that, regardless of the difference between the target humidity and the current ambient humidity measured with the humidity sensor, when the humidity requirement is not satisfied, that is, when the difference between the target humidity that the user wants to reach and the current ambient humidity measured with the humidity sensor is higher than the third preset value, after the humidifying device 10 is turned on, the enhancement mode is first forcibly performed, and then it is determined whether the enhancement mode or the normal mode or the humidifying mode is subsequently employed according to the difference between the target humidity that the user wants to reach and the current ambient humidity measured with the humidity sensor. Therefore, after the humidifying device 10 is started, the humidifying device 10 can be humidified rapidly, so that the current ambient humidity can meet the requirement as soon as possible, and the comfort of a user is improved.
The first operation enhancement mode of the humidifying device 10 may be manual control or automatic control of the humidifying device 10.
For example, in some examples of the present invention, after the humidifying device 10 is turned on, the humidifying device 10 is first operated in the enhanced mode, and during the operation in the enhanced mode, the humidity sensor acquires the humidity of the current environment in real time, and then when the difference between the target humidity that the user wants to reach and the current environment humidity measured by the humidity sensor is greater than or equal to a first preset value, the humidifying device 10 can be controlled to continue to operate in the enhanced mode, so as to accelerate the humidifying speed, so that the current environment humidity reaches the target humidity as soon as possible, and the user requirement is met; when the difference between the target humidity which the user wants to reach and the current ambient humidity measured by the humidity sensor is larger than a second preset value and smaller than a first preset value, the first preset value is larger than the second preset value, the humidifying device 10 can be controlled to be switched from the enhancement mode to the normal mode to operate, the stable operation of the humidifying device 10 is ensured, the stable rising of the current ambient humidity is ensured, and the comfort of the user is ensured; when the difference between the target humidity which the user wants to reach and the current ambient humidity measured by the humidity sensor is smaller than or equal to a second preset value and larger than or equal to a third preset value, the second preset value is larger than the third preset value, so that the humidifying device 10 can be controlled to be switched from the normal mode to the energy-saving mode or directly switched from the enhancement mode to the energy-saving mode, the difference between the target humidity set by the user and the current ambient humidity measured by the humidity sensor is smaller, the current ambient humidity is very close to the target humidity, the current ambient humidity is mainly used for reducing the humidifying strength, and the energy-saving requirement is met to the greatest extent on the premise of meeting the humidifying requirement.
In some embodiments of the present invention, as shown in fig. 1, a humidifying device 10 includes a water tank 1, a heater 2, a solenoid pump 4, and a pipe 3 connecting the water tank 1 and the heater 2, the heater 2 is formed with a heating chamber 21, the solenoid pump 4 is provided on the pipe 3 and is used to pump water in the water tank 1 into the heater 2, and when the temperature of the heating chamber 21 reaches a set temperature, water is added to the heating chamber 21, including:
when the temperature of the heating chamber 21 reaches the set temperature, the on-off of the electromagnetic pump 4 is controlled to add water to the heating chamber 21. Thereby facilitating the control of the amount of water added and the speed of water added by the electromagnetic pump 4, and better meeting the humidification demand. For example, when the difference between the target humidity and the current ambient humidity is large, the on-time of the electromagnetic pump 4 may be controlled to be longer or the flow rate of the electromagnetic pump 4 may be controlled to be larger, and when the difference between the target humidity and the current ambient humidity is small, the on-time of the electromagnetic pump 4 may be controlled to be shorter or the flow rate of the electromagnetic pump 4 may be controlled to be smaller.
Further, as shown in fig. 8, the humidifying device 10 further includes a control circuit, and the control circuit is used for controlling on-off of the electromagnetic pump 4; when the temperature of the heating cavity 21 reaches the set temperature, the on-off of the electromagnetic pump 4 is controlled to add water to the heating cavity 21, which comprises:
When the temperature of the heating chamber 21 reaches the set temperature, a preset PWM (pulse width modulation) modulation signal is input to the control circuit to control the on-off of the electromagnetic pump 4 to add water to the heating chamber 21. Thereby being convenient for controlling the on-off of the electromagnetic pump 4, having flexible adjustment mode, being capable of adjusting the humidification intensity of the humidifying device 10 and having no noise.
In the related art, the relay is controlled to be frequently turned on/off by continuously switching the relay, so that the service life of the relay is shortened, and noise is generated.
Specifically, as shown in fig. 8, when the MCU sends a PWM modulation signal, the triode Q1 turns on and off along with the frequency of the PWM modulation signal, and the triode Q1 drives the solid state relay IC1 to output a PWM wave to the thyristor TR1 at the 6 th pin, and the high voltage thyristor TR1 drives the electromagnetic pump 4 again and performs reciprocating mechanical motion according to the frequency and the duty ratio of the PWM modulation signal.
Still further, at least one of the set temperature and the PWM modulated signal is associated with an operating mode of the humidifying device 10, which includes at least one of an enhanced mode, a normal mode, and an energy-saving mode. The set temperature is the temperature in the heating chamber 21 when water needs to be added into the heating chamber 21, the set temperature of the heating chamber 21 may be related to the operation mode, and the PWM modulation signal may also be related to the operation mode.
For example, in different modes of operation, at least one of the temperature and PWM modulation signal in the heating chamber 21 is different when water is required to be added to the heating chamber 21. Therefore, the humidification effects achieved by the enhancement mode, the common mode and the energy-saving mode are different, and different requirements of users are met.
Further, the input PWM modulation signal has a first start-up duty cycle when the humidifying device 10 is in the normal mode of operation, the input PWM modulation signal has a second start-up duty cycle when the humidifying device 10 is in the energy-saving mode of operation, and the input PWM modulation signal has a third start-up duty cycle when the humidifying device 10 is in the boost mode of operation. It will be appreciated that the first duty cycle of the input PWM modulated signal may be a first start duty cycle when the humidifying device 10 is in the normal mode of operation, the first duty cycle of the input PWM modulated signal may be a second start duty cycle when the humidifying device 10 is in the energy-saving mode of operation, and the first duty cycle of the input PWM modulated signal may be a third start duty cycle when the humidifying device 10 is in the boost mode of operation.
The duty ratio of the preset PWM modulation signal input to the control circuit when the electromagnetic pump 4 is controlled to be turned on and off is a ratio of the time of controlling the electromagnetic pump 4 to the total time of one period within one period of the PWM modulation signal.
In some examples of the present invention, when the user manually starts the boost mode, the normal mode, or the energy-saving mode, the corresponding boost mode, the normal mode, or the energy-saving mode starts, and accordingly, in the normal mode, the duty cycle of the first period of the input PWM modulation signal may be the first start duty cycle, the duty cycle of the first period of the input PWM modulation signal may be the second start duty cycle, and in the energy-saving mode, the duty cycle of the first period of the input PWM modulation signal may be the third start duty cycle.
Or, the humidifying device 10 is turned on to obtain the current ambient humidity, when the temperature in the heating cavity 21 reaches the set temperature, the current ambient humidity is obtained, the operation mode of the humidifying device 10 is determined according to the difference between the target humidity which the user wants to reach and the current ambient humidity measured by the humidity sensor, and when the difference between the target humidity which the user wants to reach and the current ambient humidity measured by the humidity sensor is greater than or equal to a first preset value, the humidifying device 10 is controlled to operate in an enhanced mode, so that the humidifying speed is increased, the current ambient humidity reaches the target humidity as soon as possible, and the user requirements are met. Accordingly, when the humidifying device 10 starts the boost mode, the duty ratio of the first period of the input PWM modulation signal may be the third start duty ratio.
When the difference between the target humidity which the user wants to reach and the current ambient humidity measured by the humidity sensor is larger than a second preset value and smaller than a first preset value, the first preset value is larger than the second preset value, the humidifying device 10 is controlled to operate in a common mode, stable operation of the humidifying device 10 is guaranteed, stable rising of the current ambient humidity is guaranteed, and comfort of the user is guaranteed. Accordingly, when the humidifying device 10 starts the normal mode, the duty ratio of the first period of the input PWM modulation signal may be the first start duty ratio.
When the difference between the target humidity which the user wants to reach and the current ambient humidity measured by the humidity sensor is smaller than or equal to a second preset value and larger than or equal to a third preset value, wherein the second preset value is larger than the third preset value, the humidifying device 10 is controlled to operate in an energy-saving mode, the actual difference calculated by the target humidity set by the user and the current ambient humidity measured by the humidity sensor is smaller, the current ambient humidity is very close to the target humidity, the current ambient humidity is mainly used for reducing the humidifying strength, and the energy-saving requirement is met to the greatest extent on the premise of meeting the humidifying requirement. Accordingly, when the humidifying device 10 starts the energy saving mode, the duty ratio of the first period of the input PWM modulation signal may be the second start duty ratio.
The third start duty ratio is greater than the first start duty ratio and greater than the second start duty ratio, so that the on time of the electromagnetic pump 4 in the first period of the PWM modulation signal input during start-up of the boost mode is greater than the on time of the electromagnetic pump 4 in the first period of the PWM modulation signal input during start-up of the normal mode and the energy-saving mode, so that the water quantity introduced into the heating cavity 21 by the water tank 1 is greater, the water vapor generated by heating the heating cavity 21 is greater, the humidifying effect in the boost mode is higher than that in the normal mode and the energy-saving mode, and the humidifying intensity of the humidifying device 10 can be adjusted by adjusting the operation mode of the humidifying device 10.
Meanwhile, the first start-up duty cycle is less than 100%, the second start-up duty cycle is less than 100%, and the third start-up duty cycle is less than 100%. Therefore, when the heating cavity 21 is hot, the risk that a large amount of low-temperature water is quickly introduced into the heating cavity 21 due to the fact that part of low-temperature water is not completely vaporized and is quickly sprayed out of the heating cavity 21 under the action of internal pressure to cause high-temperature liquid to drop can be avoided when the heating cavity 21 is in the energy-saving mode, the enhancement mode and the normal mode, and meanwhile, the humidifying effect of the humidifying device 10 can be guaranteed due to the combination and switching of the three modes.
In the related art, in order to avoid the above problems, the power of the heating tube is reduced so as to prevent the temperature of the cavity from being too high, or an electromagnetic pump with smaller flow is selected. However, the reduction of the power of the heating tube and the selection of the electromagnetic pump with smaller flow rate can cause serious reduction of the humidifying power, and the reduction of the flow rate of the electromagnetic pump can even cause overheat of the heating cavity, thereby generating overheat protection.
Alternatively, the first start duty cycle may be 10%, the second start duty cycle may be the same as or different from the first start duty cycle, in this embodiment of the present invention, the second start duty cycle may be the same as or 10% from the first start duty cycle, and the third start duty cycle may be 50%.
In addition, the PWM modulation signal input at the time of the normal mode may have a first maximum duty ratio, and the PWM modulation signal input at the time of the energy saving mode may have a second maximum duty ratio, wherein the first maximum duty ratio may be greater than the second maximum duty ratio. It can be understood that, in the normal mode operation, the duty ratio of the plurality of periods of the input PWM modulation signal has the maximum duty ratio, which is the first maximum duty ratio; when the electromagnetic pump 4 is controlled by inputting the PWM modulation signal to the control circuit, the maximum time of conduction in the normal mode in each period of the input PWM modulation signal is longer than the maximum time of conduction in the energy-saving mode. Therefore, the energy-saving purpose can be realized on the premise of meeting the humidification requirement.
In some embodiments of the present invention, as shown in fig. 5 and 10, if the operation mode of the humidifying device 10 is the normal mode, when the temperature of the heating chamber 21 reaches the set temperature, a preset PWM modulation signal is input to the control circuit to control the on-off of the electromagnetic pump 4 to add water to the heating chamber 21, which includes:
when the temperature of the heating cavity 21 reaches a first preset temperature, the electromagnetic pump 4 is started, and the duty ratio of the PWM modulation signal is controlled to be a first starting duty ratio; specifically, the heating pipe in the heating cavity 21 is always working, the temperature in the heating cavity 21 rises, in the heating process, whether the temperature of the heating cavity 21 reaches the first preset temperature can be judged in real time, or whether the temperature of the heating cavity 21 reaches the first preset temperature is judged every certain time, when the temperature of the heating cavity 21 does not reach the first preset temperature, whether the temperature of the heating cavity 21 reaches the first preset temperature is continuously judged, until the temperature of the heating cavity 21 is determined to rise to the first preset temperature. After it is determined that the temperature of the heating chamber 21 has risen to the first preset temperature, the electromagnetic pump 4 is turned on at this time, and the duty ratio of the PWM modulation signal is controlled to be the first start duty ratio.
After the preset time, the duty ratio of the PWM modulation signal is periodically increased by a first preset duty ratio; it will be appreciated that the duty cycle of the input PWM modulated signal is increased by a first preset duty cycle every preset time, and that during each period of the PWM modulated signal, the electromagnetic pump 4 is turned on for a period of time, turned off for a period of time, and the electromagnetic pump 4 is turned on and off for a reciprocating cycle. It is thereby possible to prevent the electromagnetic pump 4 from being suddenly turned on, causing a large amount of low-temperature water to rapidly enter the heating chamber 21, resulting in the liquid that is not completely vaporized being squeezed by the internal pressure, resulting in the heating chamber 21 ejecting high-temperature liquid.
When the duty ratio of the input PWM modulation signal reaches the first maximum duty ratio or the time of turning on the electromagnetic pump 4 cumulatively reaches the first preset time or the temperature of the heating chamber 21 is lower than the third preset temperature, the electromagnetic pump 4 is turned off at this time, wherein the third preset temperature is smaller than the first preset temperature. In the normal mode of operation, the duty cycle of the PWM modulation signal is gradually increased, the duty cycle of the PWM modulation signal may be increased to a first maximum duty cycle, each cycle of the electromagnetic pump 4 has an on-time, and the sum of the on-times of the multiple cycles is the accumulated on-time of the electromagnetic pump 4.
In the normal mode, when the duty ratio of the PWM modulation signal reaches the first maximum duty ratio and the temperature of the heating chamber 21 is lower than the third preset temperature and the time for which the electromagnetic pump 4 is turned on cumulatively reaches the first preset time is met, the electromagnetic pump 4 is turned off, so that the heating chamber 21 is heated continuously.
Acquiring the current ambient humidity when the accumulated closing time of the electromagnetic pump 4 reaches a second preset time or the temperature of the heating cavity 21 reaches a second preset temperature; the temperature of the heating cavity 21 is obtained in real time in the heating process of the heating cavity 21, whether the temperature of the heating cavity 21 reaches a second preset temperature or not is judged, whether the accumulated closing time of the electromagnetic pump 4 reaches the second preset time or not is judged, wherein the accumulated closing time of the electromagnetic pump 4 is counted from a normal mode, and when the temperature of the heating cavity 21 reaches the second preset temperature and the accumulated closing time of the electromagnetic pump 4 reaches any one of the two conditions of the second preset time, the current environmental humidity is obtained.
If the current ambient humidity reaches the preset humidity, ending the normal mode; otherwise, a step of acquiring the temperature of the heating chamber 21 is performed, wherein the second preset temperature is greater than the first preset temperature.
If the current ambient humidity reaches the preset humidity, the normal mode may be ended when the difference between the target humidity and the current ambient humidity is less than or equal to the second preset value and greater than or equal to the third preset value, and the humidifying device 10 is switched to the energy-saving mode, or the humidifying device 10 is directly turned off when the difference between the target humidity and the current ambient humidity is less than the third preset value.
In some embodiments of the present invention, the second preset temperature is 150 degrees, the third preset temperature is 100 degrees, the first start duty cycle is 10%, the first maximum duty cycle is 100%, the first preset duty cycle is 10%, the first preset temperature is 120 degrees, the first preset time is 3s, the second preset time is 6s, when the humidifying device 10 is controlled to operate in the normal mode, when the temperature of the heating chamber 21 reaches the set temperature, a preset PWM modulation signal is input to the control circuit to control the on/off of the electromagnetic pump 4 to add water to the heating chamber 21, including:
Judging whether the temperature of the heating cavity 21 reaches 120 degrees, and continuously judging whether the temperature of the heating cavity 21 reaches 120 degrees when the temperature of the heating cavity 21 does not reach 120 degrees until the temperature of the heating cavity 21 is determined to reach 120 degrees. When the temperature of the heating cavity 21 reaches 120 ℃, the electromagnetic pump 4 is started, and the duty ratio of the PWM modulation signal is controlled to be 10%;
after 200ms, the duty ratio of the PWM modulation signal is periodically increased by 10%, and the reciprocating cycle is conducted and closed;
acquiring the temperature of the heating cavity 21 through the temperature sensor 24, detecting the duty ratio of PWM and the accumulated opening time of the electromagnetic pump 4, and closing the electromagnetic pump 4 when the duty ratio of the PWM modulation signal reaches 100% or the accumulated opening time of the electromagnetic pump 4 reaches 3s or the temperature of the heating cavity 21 is lower than 100 ℃;
when the accumulated closing time of the electromagnetic pump 4 reaches 6s or the temperature of the heating cavity 21 reaches 150 ℃, acquiring the current ambient humidity;
if the difference between the target humidity and the current ambient humidity is less than or equal to 10%, the normal mode is ended, and the energy-saving mode can be switched to or the humidifying device 10 can be turned off when the difference between the target humidity and the current ambient humidity is less than or equal to 5%;
otherwise, a step of acquiring the temperature of the heating chamber 21 is performed.
In some embodiments of the present invention, as shown in fig. 6 and 9, if the operation mode of the humidifying device 10 is the enhancement mode, when the temperature of the heating chamber 21 reaches the set temperature, a preset PWM modulation signal is input to the control circuit to control the on-off of the electromagnetic pump 4 to add water to the heating chamber 21, which includes:
when the temperature of the heating cavity 21 reaches a second preset temperature, the electromagnetic pump 4 is started, and the duty ratio of the PWM modulation signal is controlled to be a third starting duty ratio; specifically, the heating pipe in the heating cavity 21 is always working, the temperature in the heating cavity 21 rises, in the heating process, whether the temperature of the heating cavity 21 reaches the second preset temperature can be judged in real time, or whether the temperature of the heating cavity 21 reaches the second preset temperature is judged every certain time, when the temperature of the heating cavity 21 does not reach the second preset temperature, whether the temperature of the heating cavity 21 reaches the second preset temperature is continuously judged, until the temperature of the heating cavity 21 is determined to rise to the second preset temperature.
After the temperature of the heating cavity 21 is determined to be increased to the second preset temperature, the electromagnetic pump 4 is started at this time, the duty ratio of the PWM modulation signal is controlled to be the third start duty ratio, the duty ratio of the PWM modulation signal is kept unchanged, and the on-state and off-state actions are reciprocally circulated. It can be understood that the PWM modulation signal has a plurality of periods, when the boost mode is started, that is, when the PWM modulation signal controls the electromagnetic pump 4 to start to be turned on, the duty cycle of the first period of the input PWM modulation signal may be the third start duty cycle, and the duty cycle of each period of the subsequent PWM modulation signal may be the third start duty cycle, and in each period of the PWM modulation signal, the electromagnetic pump 4 is turned on for a period of time, turned off for a period of time, and the electromagnetic pump 4 is turned on and off for a reciprocating cycle in a plurality of periods, so as to avoid overflow caused by excessive flow.
When the temperature of the heating chamber 21 is lower than a third preset temperature, which is lower than the second preset temperature, the electromagnetic pump 4 is turned off. After the enhancement mode is started, low-temperature liquid in the water tank 1 enters the heating cavity 21, so that the temperature of the heating cavity 21 is reduced, the effect of generating steam is reduced after the temperature of the heating cavity 21 is reduced to a certain extent, in the invention, whether the temperature of the heating cavity 21 is lower than a third preset temperature is judged, after the fact that the temperature of the heating cavity 21 is lower than the third preset temperature is determined, the electromagnetic pump 4 is turned off, the electromagnetic pump 4 is prevented from continuously driving low-temperature water in the water tank 1 to continuously flow into the heating cavity 21, and therefore the temperature of the heating cavity 21 is continuously increased, and the heating effect of the heating cavity 21 is ensured.
Acquiring the current environmental humidity; if the current ambient humidity reaches the preset humidity, ending the enhancement mode; otherwise, a step of acquiring the temperature of the heating chamber 21 is performed.
It should be noted that, if the current ambient humidity reaches the preset humidity, the enhancement mode may be ended, when the difference between the target humidity and the current ambient humidity is smaller than the first preset value, the enhancement mode may be ended, or when the humidifying device 10 is switched to the normal mode or the energy-saving mode, or when the difference between the target humidity and the current ambient humidity is smaller than the third preset value, the humidifying device 10 is directly turned off.
It should be noted that the second preset temperature in the normal mode and the second preset temperature in the enhanced mode may be the same, may be different, and the third preset temperature in the normal mode and the third preset temperature in the enhanced mode may be the same or different. In the specific description of the present invention, the second preset temperature in the normal mode is the same as the second preset temperature in the enhanced mode, and the third preset temperature in the normal mode is the same as the third preset temperature in the enhanced mode.
In some examples of the present invention, the second preset temperature is 150 degrees, the period of the PWM modulation signal is 400ms, the third preset temperature is 100 degrees, the third start duty ratio is 50%, when the humidifying device 10 is controlled to operate in the enhanced mode, when the temperature of the heating chamber 21 reaches the set temperature, the preset PWM modulation signal is input to the control circuit to control the on-off of the electromagnetic pump 4 to add water to the heating chamber 21, which includes:
judging whether the temperature of the heating cavity 21 reaches 150 degrees, and continuously judging whether the temperature of the heating cavity 21 reaches 150 degrees when the temperature of the heating cavity 21 does not reach 150 degrees until the temperature of the heating cavity 21 is determined to reach 150 degrees. When the temperature of the heating cavity 21 reaches 150 ℃, the electromagnetic pump 4 is started, and the duty ratio of the PWM modulation signal is controlled to be 50%;
The duty ratio of the PWM modulation signal is kept unchanged, the PWM modulation signal is conducted for 200ms, the PWM modulation signal is closed for 200ms, and the PWM modulation signal is conducted and closed in a reciprocating cycle mode;
detecting the temperature of the heating cavity 21 in real time through the temperature sensor 24, judging whether the temperature of the heating cavity 21 is lower than 100 ℃, continuously judging whether the temperature of the heating cavity 21 is lower than 100 ℃ when the temperature of the heating cavity 21 is not lower than 100 ℃ until the temperature of the heating cavity 21 is determined to be lower than 100 ℃, and turning off the electromagnetic pump 4 when the temperature of the heating cavity 21 is lower than a third preset temperature;
acquiring current environment humidity, if the difference between the target humidity and the current environment humidity is less than 40%, ending the enhancement mode, switching to a common mode when the difference between the target humidity and the current environment humidity is greater than or equal to 10%, switching to an energy-saving mode when the difference between the target humidity and the current environment humidity is less than 10%, or directly closing the humidifying device 10 when the difference between the target humidity and the current environment humidity is less than 5%;
otherwise, a step of acquiring the temperature of the heating chamber 21 is performed.
In some embodiments of the present invention, as shown in fig. 7 and 11, if the operation mode of the humidifying device 10 is the energy-saving mode, when the temperature of the heating chamber 21 reaches the set temperature, a preset PWM modulation signal is input to the control circuit to control the on-off of the electromagnetic pump 4 to add water to the heating chamber 21, which includes:
When the temperature of the heating cavity 21 reaches a first preset temperature, the electromagnetic pump 4 is started, and the duty ratio of the PWM modulation signal is controlled to be a second starting duty ratio; specifically, the heating pipe in the heating cavity 21 is always working, the temperature in the heating cavity 21 rises, in the heating process, whether the temperature of the heating cavity 21 reaches the first preset temperature can be judged in real time, or whether the temperature of the heating cavity 21 reaches the first preset temperature is judged every certain time, when the temperature of the heating cavity 21 does not reach the first preset temperature, whether the temperature of the heating cavity 21 reaches the first preset temperature is continuously judged, until the temperature of the heating cavity 21 is determined to rise to the first preset temperature. After it is determined that the temperature of the heating chamber 21 has risen to the first preset temperature, the electromagnetic pump 4 is turned on at this time, and the duty ratio of the PWM modulation signal is controlled to be the second start duty ratio.
After the preset time, the duty ratio of the PWM modulation signal is periodically increased by a second preset duty ratio; it will be appreciated that the duty cycle of the input PWM modulated signal is increased by a second preset duty cycle every preset time, and that during each period of the PWM modulated signal, the electromagnetic pump 4 is turned on for a period of time, turned off for a period of time, and the electromagnetic pump 4 is turned on and off for a reciprocating cycle. It is thereby possible to prevent the electromagnetic pump 4 from being suddenly turned on, causing a large amount of low-temperature water to rapidly enter the heating chamber 21, resulting in the liquid that is not completely vaporized being squeezed by the internal pressure, resulting in the heating chamber 21 ejecting high-temperature liquid.
Closing the electromagnetic pump 4 when the duty ratio of the PWM modulation signal reaches a second maximum duty ratio or the accumulated time of opening the electromagnetic pump 4 reaches a first preset time or the temperature of the heating chamber 21 is lower than a third preset temperature, wherein the third preset temperature is lower than the first preset temperature; in the energy-saving mode, the duty ratio of the input PWM modulation signal is gradually increased, the duty ratio of the PWM modulation signal may be increased to a second maximum duty ratio, each cycle of the electromagnetic pump 4 has an on-time, and the sum of the on-times of the multiple cycles is the accumulated on-time of the electromagnetic pump 4.
In the energy-saving mode, when the duty ratio of the PWM modulation signal reaches the second maximum duty ratio and the temperature of the heating cavity 21 is lower than the third preset temperature and the accumulated time for turning on the electromagnetic pump 4 reaches the first preset time, the electromagnetic pump 4 is turned off, so that the heating cavity 21 continues to heat.
When the accumulated closing time of the electromagnetic pump 4 reaches a second preset time or the temperature of the heating cavity 21 reaches a second preset temperature, the current ambient humidity is obtained, wherein the second preset temperature is larger than the first preset temperature. The temperature of the heating cavity 21 is obtained in real time in the heating process of the heating cavity 21, whether the temperature of the heating cavity 21 reaches a second preset temperature or not is judged, whether the accumulated closing time of the electromagnetic pump 4 reaches the second preset time or not is judged, wherein the accumulated closing time of the electromagnetic pump 4 is counted from a normal mode, and when the temperature of the heating cavity 21 reaches the second preset temperature and the accumulated closing time of the electromagnetic pump 4 reaches any one of the two conditions of the second preset time, the current environmental humidity is obtained.
If the current ambient humidity reaches the preset humidity, the humidifying device 10 is turned off; otherwise, a step of acquiring the temperature of the heating chamber 21 is performed.
It should be noted that the first preset temperature in the energy-saving mode may be the same as the first preset temperature in the normal mode, may be different, the second preset temperature in the energy-saving mode may be the same as the second preset temperature in the normal mode, may be different, and the third preset temperature in the energy-saving mode may be the same as the third preset temperature in the normal mode, or may be different. The first preset time in the energy-saving mode and the first preset time in the normal mode may be the same, may be different, the second preset time in the energy-saving mode and the second preset time in the normal mode may be the same, may be different, and the first preset duty ratio in the energy-saving mode and the second preset duty ratio in the normal mode may be the same, may be different.

For example, when the second preset temperature is 150 degrees, the period of PWM is 400ms, the third preset temperature is 100 degrees, the first start duty cycle is 10%, the first maximum duty cycle is 30%, the first preset duty cycle is 10%, the first preset temperature is 120 degrees, the first preset time is 3s, the second preset time is 6s, when the humidifying device 10 is controlled to operate in the energy-saving mode, when the temperature of the heating chamber 21 reaches the set temperature, a preset PWM modulation signal is input to the control circuit to control the on/off of the electromagnetic pump 4 to add water to the heating chamber 21, which includes:
judging whether the temperature of the heating cavity 21 reaches 120 degrees, and continuously judging whether the temperature of the heating cavity 21 reaches 120 degrees when the temperature of the heating cavity 21 does not reach 120 degrees until the temperature of the heating cavity 21 is determined to reach 120 degrees. When the temperature of the heating cavity 21 reaches 120 ℃, the electromagnetic pump 4 is started, and the duty ratio of the PWM modulation signal is controlled to be 10%;
