When the atomizer detects dry burning or water shortage, the power-off protection can be automatically carried out, or water can be automatically added. However, the life of the atomizer is inevitably affected after the atomizer is dried. Therefore, in order to judge whether the atomizer meets the service life requirement, the atomizer needs to be subjected to a service life test, so that the product quality is ensured.
Therefore, the technical problem to be solved by the invention is to perform a life test on the atomizer in order to judge whether the atomizer meets the life requirement. Thereby providing a testing method and a testing device for the service life of the atomizer.
Example 1
As shown in fig. 1, an embodiment of the present invention provides a method for testing the lifetime of an atomizer, where the method includes:
s1, obtaining the effective dry burning times of an atomizer;
when the lifetime of the atomizer in the humidifier is to be detected, the water tank of the humidifier needs to be kept in a water-free state, and the atomizer needs to be started in the water-free state. And then detecting the oscillation voltage of the atomizer, and judging the working state of the atomizer according to the change of the oscillation voltage after the oscillation voltage of the atomizer is obtained. Specifically, when the detected oscillation voltage is within a preset range, the atomizer is considered to be in a dry-burning state; and when the detected oscillation voltage is out of the preset range, the atomizer is considered to be in a non-dry-burning state.
The dry burning detection process comprises three continuous detection steps, and if no dry burning signal exists in one detection step in the detection process, the dry burning detection process is restarted. If the three continuous detection steps have dry burning signals, the dry burning detection process is considered as effective dry burning. And controlling the counter to add 1, and then obtaining the effective dry-burning times of the atomizer through the total counting number of the counter.
And after the primary dry combustion detection process is determined as effective dry combustion, controlling the atomizer to pause for C time, and then starting the next dry combustion detection process. Until the effective dry burning times reach the preset times.
In this embodiment, the C time may be 2 minutes. Of course, a person skilled in the art may adjust the specific time length of the time C according to actual situations, and this embodiment is merely an example, and is not limited thereto, and the same technical effect may be achieved.
S2, when the effective dry burning times reach preset times, adding water into the atomizer, and controlling the atomizer to fog;
when the effective dry-burning times reach the preset times, the water inlet device of the humidifier is controlled to add water into the water tank, the atomizer is controlled to work because the atomizer is in the water tank, and the atomizer starts to emit fog after starting to work.
And S3, acquiring the current fog output of the atomizer, and determining whether the service life of the atomizer meets a preset service life requirement or not according to the current fog output.
After the atomizer generates fog, the current fog output amount of the atomizer is obtained, and whether the service life of the atomizer meets the service life requirement or not is determined according to the fog output amount. Specifically, after the current mist output amount of the atomizer is obtained, the numerical relationship between the current mist output amount and the preset mist output amount is compared, and the mist output attenuation amount is obtained according to the difference between the preset mist output amount and the current mist output amount. Then judging whether the fog attenuation is smaller than a first preset threshold value, if so, indicating that the atomizer works normally, and judging that the service life of the atomizer meets the preset service life requirement; and if not, judging that the service life of the atomizer does not meet the preset service life requirement.
So set up, after the effective dry combustion number of times of atomizer reached preset number of times, if the play fog decrement of atomizer had been less than the play fog decrement that the life-span requirement of atomizer will reach, explain that the atomizer can normally work to can prove that the life-span of this atomizer that the test was accomplished satisfies preset life-span requirement, this atomizer satisfies quality standard promptly, and then can guarantee product quality.
In some embodiments of the invention, before adding water to the atomizer, further comprising:
and S4, controlling the atomizer to stop working.
And after the effective dry-burning times reach a preset value, controlling the atomizer to stop working, preparing to add water into the humidifier, and starting to detect the service life of the atomizer in the humidifier.
In some embodiments of the present invention, before obtaining the number of effective dry burns of the atomizer, the method further comprises:
s5, detecting the working state of the atomizer according to a preset dry burning detection method, and judging whether the atomizer is effectively dry burning or not;
specifically, when the lifetime of the nebulizer in the humidifier is to be detected, it is necessary to keep the water tank of the humidifier in a water-free state and start the nebulizer in the water-free state. And then detecting the oscillation voltage of the atomizer, and judging the working state of the atomizer according to the change of the oscillation voltage after the oscillation voltage of the atomizer is obtained. Specifically, when the detected oscillation voltage is within a preset range, the atomizer is considered to be in a dry-burning state; and when the detected oscillation voltage is out of the preset range, the atomizer is considered to be in a non-dry-burning state.
And S6, when the atomizer is effectively dried, increasing the effective dry-burning times of the atomizer by a preset value. And when the atomization is invalid dry burning, continuously detecting the working state of the atomizer according to a preset dry burning detection method. In the present embodiment, the preset value may be 1.
And after the atomizer is in a dry-burning state, controlling the atomizer to stop working for A seconds, after A seconds, controlling the atomizer to start working for B seconds, and judging whether a dry-burning signal is acquired within the time of B seconds, namely judging whether the oscillation voltage is within a preset range within the time of B seconds. And if the oscillation voltage is always within the preset range within the time of B seconds, the atomizer is considered to be in a dry-burning state. And then, a circulation detection step of controlling the atomizer to stop working for A seconds and controlling the atomizer to start working for B seconds is carried out.
The dry-fire detection process includes the three consecutive detection steps, as shown in fig. 2, specifically as follows:
1) and after the atomizer is in a dry-burning state, controlling the atomizer to stop working for A seconds, and after A seconds, starting a PWM signal to enable the atomizer to start working. When the atomizer starts to work, a voltage signal needs to be acquired by delaying for B seconds through the water shortage detection port. Therefore, whether the voltage signal is a water shortage signal (dry burning signal) is judged according to the voltage signal sampled by the water shortage detection port, namely whether the oscillation voltage is within a preset range is judged within B seconds. If the oscillation voltage is always within the preset range within the time of B seconds, the atomizer is considered to be in a dry-burning state, and the water shortage signal (dry-burning signal) is effective. Then stopping the counter to be 0, controlling the atomizer to be switched to the lowest gear to work, and entering the step 2);
2) the water shortage detection port collects the voltage signal again, whether the voltage signal is a water shortage signal (dry burning signal) is judged according to the voltage signal sampled by the water shortage detection port, namely whether the oscillation voltage is within a preset range is judged within B seconds. If the oscillation voltage is always within the preset range within the time of B seconds, the atomizer is considered to be in a dry-burning state, and the water shortage signal (dry-burning signal) is effective. When the water shortage signal is detected again, the atomizer stops working, the counter is stopped to add 1, the atomizer works again at the lowest gear after C seconds, and the step 3) is carried out;
3) the water shortage detection port collects the voltage signal again, whether the voltage signal is a water shortage signal (dry burning signal) is judged according to the voltage signal sampled by the water shortage detection port, namely whether the oscillation voltage is within a preset range is judged within B seconds. If the oscillation voltage is always within the preset range within the time of B seconds, the atomizer is considered to be in a dry-burning state, and the water shortage signal (dry-burning signal) is effective. When the water shortage signal is detected again, the atomizer stops working. When the counter is stopped and added to 2, the whole machine enters a water shortage protection state. After entering the water shortage protection, the atomizer and other loads are stopped, the whole machine enters a protection state, and the display prompts a user that the whole machine is in water shortage and needs to be added with water in time so as to avoid influencing the use. After a user adds water, a switch key is pressed down or a rotary positioner switch detects voltage change, and then the water shortage protection is quitted and the working state is directly entered. And (4) delaying the time of A seconds again to start the PWM driving atomizer to work, and detecting whether water is short or not in real time.
In the detection process, if no water shortage signal is detected within the continuous time D seconds, the counter is stopped to clear 0, the actual gear humidification is resumed, namely if no dry-burning signal exists in the detection step, the dry-burning detection process is restarted. If the three continuous detection steps have dry burning signals, the dry burning detection process is considered as effective dry burning. And controlling the counter to add 1, and then obtaining the effective dry-burning times of the atomizer through the total counting number of the counter. And after the effective dry burning is determined in the one-time dry burning detection process, the atomizer is controlled to pause for the time E, and then the next dry burning detection process is started. Until the effective dry burning times reach the preset times.
In this embodiment, a second may be 1 second, B second may be 500 milliseconds, C may be 1 second, D may be 3 seconds, and E time may be 2 minutes. Of course, those skilled in the art can adjust the specific time length of A, B, C, D, E according to actual situations, and this embodiment is merely an example and is not limited, and the same technical effects can be achieved.
In the embodiment of the present invention, before the operating state of the atomizer is continuously detected according to a preset dry-fire detection method, the method further includes:
and S7, controlling the atomizer to stop working for a preset time so that the temperature of the atomizer meets the preset temperature requirement.
Similarly, after one dry burning detection process is determined as invalid dry burning, the atomizer is controlled to pause for a preset time, wherein the preset time can be C time, and then the next dry burning detection process is started. Until the effective dry burning times reach the preset times. In addition, the water temperature is applicable to the range of 1-70 ℃ in the process.
In some embodiments of the present invention, after increasing the number of effective dry-fire times of the atomizer by a preset value when the atomization is effective dry-fire, the method further includes:
s8, obtaining the total times of all the effective dry burning times, and judging whether the total times of all the effective dry burning times reach a second preset threshold value or not;
and S9, if so, forming a prompt signal according to the total times of all the effective dry burning times.
And acquiring all effective dry-burning times of the atomizer, and then judging whether the total times of all effective dry-burning times reach a second preset threshold value. For example, the second preset threshold may be one thousand times. If yes, indicating that the end condition of the detection process is reached, forming a prompt signal according to the total times of all effective dry-burning times. The prompt signal may be, for example, a prompt tone or a prompt voice, and is not limited herein.
