Detailed Description
In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 to 3, a ceramic blade detection method, a razor detection device and a razor provided by the present application will now be described exemplarily.
The shaver includes a head, a handle, a ceramic blade, and a shaver detection device. The ceramic blade is arranged on the cutter head, the handle is connected with the cutter head, and the handle is held by hands. The razor testing device is partially mounted within the handle. The shaver monitoring device is used for detecting the use condition of the ceramic blade, and finding out the condition (abnormity) that the ceramic blade has cracks and damages and has the risk of fragmentation, thereby improving the use safety of the shaver. In this embodiment, the shaver is an electric shaver, and the ceramic blade is rotated to shave.
It has been found that when the razor is operated at a specific voltage and the ceramic blade is in a normal state, the rotational speed, rotational acceleration, amplitude in the direction of the rotational axis, and amplitude acceleration of the ceramic blade are constant (no small variations are excluded), and when there is a crack or a damage (abnormal), the rotational speed, rotational acceleration, amplitude in the direction of the rotational axis, and amplitude acceleration of the ceramic blade significantly deviate from the predetermined values, and the current of the razor also fluctuates. Based on the discovery and a plurality of experiments, the amplitude acceleration, the current and the electric quantity of the ceramic blade are used as parameters for judging whether the ceramic blade is abnormal or not, the ceramic blade is detected, and an alarm is given to a user when the ceramic blade is abnormal so as to remind the user to replace the ceramic blade in time.
Specifically, referring to fig. 1, the monitoring device for a shaver includes a measuring unit 20, a processor 10 and an alarm unit 30, wherein the measuring unit 20 is configured to measure data of amplitude, amplitude acceleration, current and/or electric quantity of the ceramic blade during actual operation, the processor 10 is electrically connected to the measuring unit 20 to obtain the data of the amplitude, amplitude acceleration, current and/or electric quantity, and compare the data with built-in model data, thereby determining whether the ceramic blade is abnormal, and the processor 10 is electrically connected to the measuring unit 20 to control the alarm unit 30 to alarm when the ceramic blade is abnormal, so as to remind a user to replace the ceramic blade in time.
It is understood that the alarm unit 30 may alarm by means of electronic information display, and may also alarm by sound and light, which is not limited herein.
The shaver monitoring device and the shaver adopting the shaver monitoring device provided by the embodiment can detect the use condition of the ceramic blade, and give an alarm to remind a user of replacing the ceramic blade in time when the ceramic blade has cracking risk due to the occurrence of cracks, damages and the like, so that the use safety of the shaver is improved.
The method for detecting a ceramic blade according to this embodiment is suitable for a ceramic blade of a shaver, and the ceramic blade has at least two operation modes, and for the sake of convenience of distinction, each operation mode is named as a first operation mode, a second operation mode, a third operation mode, and the like.
It will be understood that actual operation refers to the actual operation of the ceramic blades when the shaver is in powered operation. The sound state is relative to actual work, and the sound state refers to the operation condition of the ceramic blade when the shaver is powered on to operate under the ideal condition that the ceramic blade is sound.
The ceramic blade has various operation modes under actual working or intact conditions. The operation modes are different operation states of the shaver under different current or other conditions, mainly embodied as different rotating speeds and different pressures.
It should be noted that the designations of the first motion mode and the second motion mode only refer to different operation modes, and do not correspond to specific motion modes. For example, the movement state of the ceramic cutter during idling (when the ceramic cutter is energized but not used for shaving) is named as a first operation mode, and the movement state during shaving is classified into a second operation mode, a third operation mode, and the like according to different gear positions. It is also possible to divide the shaving operation into a first operation mode, a second operation mode, etc. according to different gear positions.
Referring to fig. 2, the ceramic blade inspection method includes a modeling step, a measuring step, and a determining step.
Modeling: establishing a model of the amplitude and/or the amplitude acceleration of the ceramic cutter in a sound state in the running mode, recording the amplitude of the ceramic blade in the first running mode as a first threshold value, recording the amplitude acceleration of the ceramic blade in the first running mode as a second threshold value, recording the amplitude of the ceramic blade in the second running mode as a third threshold value, and recording the amplitude acceleration of the ceramic blade in the second running mode as a fourth threshold value. It is understood that the data model of the ceramic blade in condition is data of the ceramic blade operating in condition (without breakage, cracks or other anomalies), which data model is determined for a particular razor ceramic blade.
Measurement: the amplitude and/or amplitude acceleration of the ceramic blade in the operation mode during actual operation are obtained, the amplitude of the ceramic blade in the first operation mode is recorded as a first amplitude, the amplitude acceleration of the ceramic blade in the first operation mode is recorded as a first acceleration, the amplitude of the ceramic blade in the second operation mode is recorded as a second amplitude, and the amplitude acceleration of the ceramic blade in the second operation mode is recorded as a second acceleration. The measurement of the actual working data of the ceramic blade can be realized by a sensor, the sensor consists of a mass block, a damper, an elastic element, a sensitive element, an adjusting circuit and the like, and the sensitive element can adopt a capacitance type, an inductance type, a strain type, a piezoresistive type, a piezoelectric type and the like. The sensor type can be selected by those skilled in the art according to actual conditions, as long as the data of the amplitude and the amplitude acceleration required to be measured by the actual operation of the ceramic blade can be sensed.
And (3) judging: and if the ceramic blade meets a first condition, judging that the ceramic blade has a fragmentation risk, otherwise, judging that the ceramic blade is in a safe use state, wherein the first condition is that the first amplitude is larger than a first threshold value, and/or the first acceleration is larger than a second threshold value.
When the motion state of the ceramic blade deviates from the normal state, the abnormality of the ceramic blade is indicated. The first mode of operation is preferably the operating state of the ceramic cutter when the shaver is switched on. When the ceramic cutter is started, the condition of the ceramic cutter is detected firstly, and the detection time is advanced as much as possible, so that the safety risk brought to a user due to sudden breakage in the operation process of the ceramic cutter blade is reduced.
In the method for detecting the ceramic blade provided by the embodiment, the operation data of the ceramic blade is obtained, and the operation data is compared with the model data to judge whether the ceramic blade has the risk of cracking. The detection method is simple and effective. The ceramic blade detection method provided by the embodiment is applied to detection of the shaver, and safety guarantee can be provided for use of the shaver.
Preferably, in the determining step, the first condition is: the first amplitude is greater than a first threshold and the second amplitude is greater than a third threshold, and/or the first acceleration is greater than a second threshold and the second acceleration is greater than a fourth threshold.
It is understood that when the motion state of the ceramic blade deviates from the normal state, it indicates that there is an abnormality in the ceramic blade. The abnormity can be caused by the conditions that cracks exist in the ceramic cutter and the like, and can also be caused by current mutation or other factors, and data of two different operation modes are selected to be used as a basis for judgment, so that the accuracy of evaluation is improved.
Preferably, data of the shaver during idling when the shaver is turned on is used as data of the first operation mode, and data of the initial moment when the ceramic blade contacts the skin of the human body is used as data of the second operation mode. The razor enters the detection of the ceramic blade immediately after the razor is started by combining the use condition, and the detection time is advanced as much as possible, so that the safety risk brought to a user by sudden breakage in the operation process of the ceramic blade is reduced.
In another embodiment of the present application, referring to fig. 2, the method for detecting a ceramic blade further includes a correction step: measuring the current of the shaver in a first operation mode and a second operation mode, if the ceramic blade meets a first condition and a second condition, judging that the ceramic blade has a fragmentation risk, otherwise, judging that the ceramic blade is in a safe use state, wherein the second condition is as follows: the current fluctuates in synchronism with the amplitude/amplitude acceleration of the ceramic blade.
When the amplitude and/or the amplitude acceleration of the ceramic blade are detected to be abnormal, the abnormal amplitude and/or the amplitude acceleration may be caused by vibration of the shaver at the moment of starting or contacting with the skin of a human body, so that the current is detected, and the detection result is corrected by including the current parameter, so that the detection accuracy is improved. And under the condition that the current and the amplitude/amplitude acceleration synchronously fluctuate, judging that the ceramic blade has a fragmentation risk, and if not, judging that the ceramic blade is in a safe use state.
Preferably, under the condition that the ceramic blade meets the first condition, whether the second condition is met is judged, if yes, the ceramic blade is judged to have a fracture risk, and if not, the ceramic blade is judged to be in a safe use state. In other words, the first condition is determined first, and the second condition is determined when the first condition is satisfied. Under the setting, if the first condition is not met, the ceramic blade is judged to be in a safe use state, and the second condition is not required to be judged, so that the operation efficiency is improved.
In another embodiment of the present application, the ceramic blade inspection method further includes a correction step of: measuring current data of the shaver, recording the current of the shaver in a first operation mode as a first current, and recording the current of the shaver in operation as a second current;
under the condition that the ceramic blade satisfies the first condition, judge whether satisfy the third condition, if satisfy, then judge that the ceramic blade has cracked risk, if not, then judge that the ceramic blade is in safe handling state, the third condition is: the difference value between the first current and the second current is larger than a fifth threshold value.
The current is detected, and the detection result is corrected by incorporating the current parameter, so that the detection accuracy is improved. The ceramic blade is judged to have the fracture risk only in the case that the amplitude/amplitude acceleration of the ceramic blade and the current are abnormal. The current abnormality is represented by a current instability (a difference value exists between the first current and the second current, the difference value is larger than a fifth threshold value, the fifth threshold value is a fixed value related to the current, and a specific numerical value of the fifth threshold value can be set according to actual conditions and is not limited here). In the case of a smooth current, it is considered that the occurrence of an abnormality in the amplitude/amplitude acceleration of the ceramic blade is not caused by a defect of the ceramic blade itself, thereby eliminating the risk of chipping of the ceramic blade.
Referring to fig. 2, the method for detecting a ceramic blade further includes a correction step: acquiring the electric quantity of the shaver; if the electric quantity is smaller than the sixth threshold value, an alarm is given out, and the power supply is turned off; and if the electric quantity is not less than the sixth threshold value, judging that the ceramic blade has the fracture risk. It is understood that the abnormal amplitude and/or amplitude acceleration of the ceramic blade may be caused by insufficient electric quantity, and the electric quantity is measured and a correction step is included to eliminate the misjudgment that the electric quantity is insufficient and the ceramic blade is at risk of cracking. The sixth threshold is a fixed value related to the electric quantity, and a specific numerical value of the sixth threshold may be set according to an actual situation, and is not limited herein.
Preferably, in the case that the ceramic blade satisfies the first condition, if the power is less than the fifth threshold, an alarm of insufficient power is issued, and the power is turned off. The first condition is judged first, and the electric quantity is judged under the condition that the first condition is met. Under the setting, if the first condition is not met, the ceramic blade is judged to be in a safe use state, and the second condition is not required to be judged, so that the operation efficiency is improved.
In another embodiment of the present application, referring to fig. 2, the method for inspecting a ceramic blade further includes a verifying step: establishing a model of the amplitude and/or amplitude acceleration of the ceramic blade under the intact state relative to the rotating speed; and measuring the amplitude and/or amplitude acceleration of the ceramic blade at different rotating speeds, and if the amplitude and/or amplitude acceleration of the ceramic blade corresponding to the different rotating speeds are matched with the model, confirming that the ceramic blade is in a safe use state.
The setting of the checking step further eliminates the risk of cracking of the ceramic blade, thereby improving the use safety of the shaver.
Preferably, the verifying step is performed when the ceramic blade is in a safe use state as a result of the determination in the correcting step. It is understood that in the determination step, the ceramic tool satisfies the first condition, i.e., is determined to have a chipping risk. Then, in a correction step, correction is performed to eliminate the deviation of the determination result from the actual value due to the influence of other factors on the amplitude/amplitude acceleration. At this time, the ceramic cutter may not be determined to be at risk of chipping although the first condition is satisfied, and the determination accuracy is further verified to ensure the use safety of the shaver.
Referring to fig. 3, an operation mode of the ceramic blade when the ceramic blade is turned on is taken as a first operation mode, and an operation mode of the ceramic blade when the ceramic blade is pressed against the skin of a human body is taken as a second operation mode, so as to exemplify a detection flow of the ceramic blade.
When the ceramic blade is started, the sensor (the measuring unit 20) measures the amplitude and/or the amplitude acceleration of the ceramic blade when the ceramic blade is started, and the current is recorded as a first amplitude, a first acceleration and a first current. And then, judging for the first time, if the first amplitude is larger than a first threshold value and/or the first acceleration is larger than a second threshold value, preliminarily considering that the ceramic blade is abnormal, and entering the next measurement: and measuring the amplitude and/or amplitude acceleration of the ceramic blade when the ceramic blade is abutted against the skin of the human body (shaving), and recording the current as a second amplitude, a second acceleration and a second current. Entering a second judgment: and if the second amplitude is larger than the third threshold value and/or the second acceleration is larger than the fourth threshold value, preliminarily judging that the ceramic blade is at risk of cracking.
And entering a correction step.
Firstly, the electric quantity condition is detected, and if the electric quantity is insufficient, a user is reminded to charge and shut down the electric vehicle. And after the user charges and restarts the machine, the ceramic blade is checked to eliminate the detection deviation caused by insufficient electric quantity.
And after the condition of insufficient electric quantity is eliminated, analyzing and judging the current condition, and if the current is stable (the difference value between the first current and the second current is not larger than a fifth threshold value) when the current is started and shaved, judging that the abnormity of the amplitude/amplitude acceleration is not caused by the self defect of the ceramic blade, thereby judging that the ceramic blade is in a safe use state. To ensure safety, a check is performed: and (4) determining whether the amplitude/amplitude acceleration is normal or not at different rotating speeds, and if so, determining that the ceramic blade is in a safe use state. And if the current measurement result shows that the current is not stable (the difference value between the first current and the second current is larger than a fifth threshold value) and the current and the amplitude/amplitude acceleration fluctuate synchronously, judging that the ceramic blade has the fracture risk. Reminding the user to replace the ceramic blade in time.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
