And when the detected capacitance value between the first net layer and the second net layer is out of the capacitance threshold interval, the blockage phenomenon of the dust screen is indicated.

Referring to fig. 2, a flowchart illustrating steps of a method for detecting a blockage according to an embodiment of the present invention is shown, where the method for detecting a blockage may be applied to an electronic device, a dust screen of the electronic device may include a first screen layer and a second screen layer, and the method for detecting a dust screen may specifically include the following steps: :
step 201: and under the condition that the dustproof net is normal, acquiring a normal voltage value between the first net layer and the second net layer through a detection circuit.
In an embodiment of the present invention, the electronic Device may be a mobile electronic Device, such as a mobile phone, a PAD (tablet android Device, tablet computer), and the like. The electronic device may also be other devices, and in particular, may be determined according to practical situations, and the embodiment of the present invention is not limited thereto.
The dustproof net refers to a dustproof net installed on a hole (such as a sound outlet) of a housing of a mobile terminal, and the dustproof net may be composed of fine meshes, so that dust, liquid and the like are easily accumulated, and the hole is blocked and the volume is reduced, for example, referring to fig. 1a, a schematic diagram of a sound outlet provided in an embodiment of the present invention is shown, and the sound outlet provided on the housing of the mobile terminal may be a circular sound outlet as shown in a left half portion of fig. 1a or a square sound outlet as shown in a right half portion of fig. 1 a.
When the sound outlet is blocked, the sound outlet area is reduced, and the quality is affected, for example, referring to fig. 1b, a schematic diagram of the sound outlet blocking provided by the embodiment of the invention is shown, and as shown in fig. 1b, when the sound outlet with a round shape or a square shape is blocked, the sound outlet area is obviously reduced.
In order to reduce the blocking area of the sound outlet, a dust screen is usually disposed on the sound outlet to reduce the blocking of the sound outlet by the blocking object. The dust screen is typically a double-mesh dust screen, and the structure of the dust screen can be described below with reference to fig. 1 c.
Referring to fig. 1c, a schematic view of a dust screen according to an embodiment of the present invention is shown, as shown in fig. 1c, P01 is an appearance surface, and for a mobile terminal, here, glass or other planar materials (such as metal, etc.); p02 is a metal decorative cover or an outer layer dust screen containing metal material, which is used as a first protection and simultaneously ensures the integrity of the appearance surface; p03 is the sound hole of the decorative cover or dust screen, the net structure, the air permeability is good, used for producing the sound; p04 is a front cavity sealing device, such as foam or silica gel, to prevent sound leakage; p05 is a dust screen with an inner layer containing metal material, and the second protection is carried out; p06 is the sound outlet hole of the inner layer dust screen, has a net structure and good air permeability and is used for sound production; p07 is a receiver or a speaker, a device for emitting sound; p08 is the electric connection point of the decorative cover or the outer layer dust screen, and is grounded; p09 is the electrical connection point of the inner dust screen for providing charge to the capacitor and detection.
In the dust screen structure, when P02 is used as the first screen layer of the dust screen, P05 is the second screen layer of the dust screen; when P02 is the second mesh layer of the dust screen, P05 is the first mesh layer of the dust screen.
When P08 is the first electrical connection point of the dust screen, P09 is the second electrical connection point of the dust screen; and when P08 is the second electrical connection point of the dust screen, P09 is the first electrical connection point of the dust screen.
P02 and P05 together form a plate capacitor, and P08 and P09 as electrical connection points can be connected to the detection circuit, respectively, and can be used for detecting the capacitance value between the first net layer and the second net layer.
The detection circuit provided by the present invention can be described as follows in conjunction with fig. 1 h.
Referring to fig. 1h, a schematic diagram of a detection circuit provided by an embodiment of the present invention is shown, as shown in fig. 1h, which is a basic capacitance detection circuit prototype (equivalent to the principle of a common capacitive microphone, where C ═ Q/U, capacitance change is converted into voltage change, and then amplified and output to a waveform detection device through a transistor Q1 for detection).
The two electrical connection points shown in fig. 1c, i.e. the first electrical connection point and the second electrical connection point, are each connected to a detection circuit, so that the voltage value between the two electrical connection points can be detected.
In the present invention, the detection circuit may be an ADC (analog-to-digital conversion) or a comparator, and in particular, may be determined according to the service requirement.
After the first electrical connection point and the second electrical connection point are energized, a voltage value between the first electrical connection point and the second electrical connection point may be obtained.
The normal voltage value is a voltage value between the first electrical connection point and the second electrical connection point detected when no clogging occurs between the dust screens.
For example, referring to fig. 1d, a schematic diagram of a flat capacitor provided in an embodiment of the present invention is shown, and as shown in fig. 1d, in a case where the dust screen is normal (that is, the dust screen is not blocked), a capacitance value between the first mesh layer and the second mesh layer is: c ═ e × S/d; wherein C is a capacitance value, e is a dielectric constant between the first net layer and the second net layer, S is an effective area between the first net layer and the second net layer, and d is a plate interval between the first net layer and the second net layer.
In the case that the dust screen is normal, after acquiring the normal voltage value between the first electrical connection point and the second electrical connection point through the detection circuit, step 202 is executed.
Step 202: and acquiring second output power of the detection circuit.
Output power (nominal power) is also called: the nominal output power refers to the maximum value of the output power which can work for a long time on the premise that the electric appliance is not distorted, and the maximum power refers to the maximum value of the instantaneous power on the premise that the electric appliance is not damaged, namely the maximum load capacity which can be borne by the electric appliance. Output power is input power-the power of the useless work.
The second output power refers to the effective power provided by the detection circuit for the first network layer and the second network layer under the condition that the dustproof network is normal.
It is understood that the second output power can be determined when the detection circuit operates, the manner of the second output power is a relatively mature technology in the field, and the embodiment of the present invention is not limited to how to obtain the first output power.
After acquiring the second output power of the detection circuit, step 203 is executed.
Step 203: and determining a normal capacitance value between the first net layer and the second net layer according to the normal voltage value and the second output power.
After obtaining the normal voltage value between the first electrical connection point and the second output power of the detection circuit, the normal capacitance value between the first network layer and the second network layer may be determined according to the normal voltage value and the second output power, and specifically, may be combined with the formula: and C is the normal capacitance value calculated by Q/U, C is the normal capacitance value, Q is the normal voltage value, and U is the second output power.
After the normal capacitance value between the first net layer and the second net layer is determined according to the normal voltage value and the second output power, step 204 is executed.
Step 204: and determining a capacitance threshold interval according to the normal capacitance value.
The reasons for the capacitance change between the first network layer and the second network layer are mainly divided into the following:
1. change of effective area of the flat plate
When the effective area between the first net layer and the second net layer changes, according to a capacitance formula: for example, referring to fig. 1e, a schematic diagram of a change in the effective area of a flat plate provided by an embodiment of the present invention is shown, as shown in fig. 1e, after a hole on a dust screen or a trim cover is blocked, since a blocking object is composed of liquid and impurities, the blocking object has a certain conductivity, and together with a metal dust screen, the effective area of the flat plate capacitor is increased, that is, the effective area between a first mesh layer and a second mesh layer is increased, so that the capacitance between the two mesh layers is increased.
2. Change of plate spacing
When the distance between the first net layer and the second net layer is changed, according to a capacitance formula: for example, referring to fig. 1f, a schematic diagram of a change in a plate spacing provided in an embodiment of the present invention is shown, as shown in fig. 1f, after a hole of the dust screen is blocked, due to unsmooth airflow, when the receiver or the speaker is in a sound producing state, the dust screen is pushed by the airflow to deform, so that a change (possibly an increase or a decrease) occurs in the plate spacing d of the parallel plate capacitor, thereby causing a change in capacitance between two mesh layers.
3. Change of medium between plates
When the dielectric constant between the first net layer and the second net layer changes, according to a capacitance formula: for example, referring to fig. 1g, a schematic diagram of the change of the medium between the flat plates provided by the embodiment of the present invention is shown, and as shown in fig. 1g, when there are many plugs between the first mesh layer and the second mesh layer, the plugs are accumulated between the two dust-proof meshes, which may cause the medium between the flat plates to change and thus change the medium constant e (which may increase or may decrease).
As can be seen from the capacitance formula, the capacitance between the first network layer and the second network layer changes when the above conditions occur.
After obtaining the normal capacitance value between the first network layer and the second network layer, a service person may give a set capacitance threshold interval (that is, including the minimum capacitance threshold value and the maximum capacitance threshold value) through a plurality of tests according to the normal capacitance value, and the process of obtaining the capacitance threshold interval may be determined according to the service requirement, which is not limited in the embodiment of the present invention.
After determining the capacitance threshold interval based on the normal capacitance value, step 205 is performed.
Step 205: acquiring a voltage value between the first electrical connection point and the second electrical connection point through a detection circuit.
After the first electrical connection point and the second electrical connection point are powered on, a voltage value between the first electrical connection point and the second electrical connection point may be acquired, and in a specific implementation, the operation of acquiring the voltage value may be performed every preset time when the screen of the mobile terminal is in a bright screen state.
The preset time may be preset by a service person, and may be 10 min, 30min, and the like, and specifically, may be determined according to actual situations.
In the invention, by setting the preset time, the voltage detection is executed once every preset time when the screen is on, so that the power consumption of the mobile terminal in standby can be saved.
After the voltage value between the first electrical connection point and the second electrical connection point is obtained by the detection circuit, step 206 is performed.
Step 206: and determining a capacitance value between the first net layer and the second net layer according to the voltage value and the first output power of the detection circuit.
The first output power refers to the effective power provided by the detection circuit for the first network layer and the second network layer.
