Detailed Description
In order that the above objects, features and advantages of embodiments of the present disclosure may be more clearly understood, a further description of aspects of embodiments of the present disclosure will be provided below. It should be noted that, without conflict, the embodiments of the present disclosure and features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments, but the disclosed embodiments may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, of the embodiments of the disclosure.
One embodiment of the present disclosure provides a method for detecting dirt on a filter, the filter being located inside a cleaning apparatus, the cleaning apparatus further including a fan inside, the filter being located in an intake passage of the fan. As shown in fig. 1, the method includes:
s101, acquiring fan parameters of a fan.
The cleaning device also comprises a data sensor, and different sensors can be used for acquiring fan parameters of the fan. Specifically, the parameters of the fan during operation are obtained in S101.
S102, determining whether the filter piece needs to be cleaned or not according to the fan parameters.
When the dirt degree of the filter paper is serious, the ventilation is influenced, so that the working condition of the fan is influenced, and the parameter change of the fan is reflected.
According to the embodiment of the disclosure, the dirt degree of the filter piece can be accurately judged by detecting the fan parameters, so that corresponding measures can be timely taken, and the normal operation of the cleaning equipment is ensured.
Specifically, the filter is located at the inlet of the air intake passage of the blower. When the fan carries out dust collection operation, air firstly passes through the filter element and then reaches the inside of the air inlet channel, so that dirt carried in the air is filtered outside. Part of dirt can drop to the dust box by oneself after the fan stops working, but part of dirt can adhere to the filter surface to influence the work effect of filter. Specifically, the filter element completely covers the inlet to ensure that all air passes through the filter element before reaching the intake passage.
In a specific embodiment, the air inlet channel is a volute structure. The air inlet channel with other structures can be used as the air inlet channel as long as the air circulation cavity is used for the fan to perform dust collection operation, and the filter element is correspondingly arranged, so that the air inlet channel is within the protection scope of the present disclosure.
In specific implementation, the step S101 further includes:
and obtaining initial fan parameters in a period of time, and averaging the initial fan parameters to obtain the fan parameters.
When the fan works, certain parameters can be influenced by the outside, so that the value at a certain moment is abnormal, and the working condition of the fan can be accurately reflected by taking the average value, so that more accurate dirt detection of the filter element can be made.
In some embodiments, the fan parameter includes a fan speed, and as shown in fig. 2, the step S102 includes:
and determining that the filter piece needs to be cleaned in response to the fan rotating speed being greater than a preset threshold.
When the dirt degree of the filter paper is serious, the ventilation can be influenced, negative pressure is formed in the air inlet channel, wind resistance is small, and therefore the rotating speed of the fan is increased. According to the embodiment, the dirt degree of the filter piece can be judged more accurately by detecting the rotating speed of the fan, so that corresponding measures can be taken in time, and the normal operation of the cleaning equipment is further ensured.
In specific implementation, obtaining the fan rotation speed includes:
and acquiring the rotation number of the fan in a period of time, and determining the rotation speed of the fan according to the rotation number/the period of time.
Specifically, the preset threshold is determined according to the rotation speed of the fan when the fan works normally, and the rotation speeds of the fans of different models are different when the fan works normally, so that excessive limitation is not made. In specific implementation, the fan can be pre-operated at rated working power/voltage before being arranged in the cleaning equipment, and at the moment, the rated rotating speed of the fan is tested, and a preset threshold value is determined according to the rated rotating speed. In a specific embodiment, the preset threshold is higher than the rated rotation speed, and redundancy is set to prevent unnecessary cleaning reminding.
In some embodiments, the blower employs constant power control.
When the dirt degree of the filter paper is serious, the ventilation is affected, so that negative pressure is formed in the air inlet channel, and the wind resistance is small; when the fan adopts constant power control, wind resistance becomes small, and power is unchanged, so that the rotating speed of the fan is increased. The fan adopting constant power control naturally increases the rotating speed of the fan when encountering the above conditions, and can further facilitate the detection of the dirt degree of the filter element through the rotating speed of the fan.
In a specific embodiment, the cleaning device further includes a hall sensor, and the fan rotation speed is obtained by using the hall sensor.
The hall sensor is a transducer which can convert a changing magnetic field into a change of output voltage, can be used for measuring the magnetic field, can also measure physical quantities which generate and influence the magnetic field, and can be used for collecting the rotating speed of a fan in the cleaning equipment based on the principle.
It should be noted that, the above-mentioned obtaining the fan rotation speed is not limited to directly obtaining the fan rotation speed, and those skilled in the art, without performing creative labor, calculate the fan rotation speed by using other parameters of the fan, and use the calculated fan rotation speed in the embodiments of the present disclosure, which are all within the scope of protection of the present disclosure.
In some embodiments, as shown in fig. 2, the step S102 further includes:
and responding to the fan rotating speed being less than or equal to a preset threshold value, and determining that the filter piece does not need to be cleaned.
After the filter piece is determined to be unnecessary to clean, the cleaning equipment is kept to work normally until the cleaning equipment is finished.
In some embodiments, as shown in fig. 2, the method further comprises:
in response to determining that the filter requires cleaning, the user is prompted to clean or replace the filter.
Specifically, the cleaning device can directly send out a prompt for cleaning or replacing the filter element, and the prompt for cleaning or replacing the filter element can also be sent to the user terminal (for example, mobile phone APP pushing).
In a specific embodiment, the fan speed at this time may be recorded as historical speed data even if it is determined that the filter does not need to be cleaned. The method may further include:
predicting future rotational speed data according to the historical rotational speed data, and judging the remaining time of the fan rotational speed greater than a preset threshold according to the future rotational speed data. In response to the cleaning device being powered on, the remaining time is less than the total time the cleaning device is next to complete cleaning, the user is immediately prompted to clean or replace the filter.
Along with the rise of the dirt degree of the filter element, the rotating speed of the fan also gradually rises, and the trend can be predicted according to the trend, if the dirt degree of the filter element is found to enable the rotating speed of the fan to exceed a preset threshold value in the next cleaning process, a user is prompted before the cleaning starts, and the high efficiency and the consistency of the cleaning are ensured.
In some embodiments, obtaining fan parameters of a fan includes:
and responding to the start of the operation of the fan, and acquiring fan parameters of the fan at intervals of preset time.
The fan parameters can be obtained at intervals for preset time, so that the dirt degree of the filter element can be detected on the basis of saving computing resources, and the working efficiency of the cleaning equipment is improved.
In some embodiments, the filter comprises a hepa filter paper.
The HEPA is a high-efficiency filter paper, and the effective rate of the HEPA reaches 99.7 percent for 0.1 micron and 0.3 micron. The material of the HEPA filter paper can be PP (polypropylene), PET (polyethylene terephthalate), PP and PET composite materials and glass fibers.
In a specific embodiment, the cross section of the hepa filter paper is wave-shaped, so as to increase the ventilation area. The HEPA filter paper can be provided with one or more layers, and can be laid flat or folded. It is within the scope of the present disclosure to provide other forms of hepa filter paper on the filter element to achieve the filtering effect.

The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present application, and the devices may interact with each other to complete the methods.
