Before introducing the over-temperature prompting method provided by the embodiment of the present application, an application scenario applicable to the over-temperature prompting method is introduced, where the application scenario includes, but is not limited to: when a rechargeable device is charged by using a wireless charging technology, in order to improve charging efficiency, the charging current is increased or the charging coil is shortened, for example, to increase the charging rate. However, the temperature of the charging portion of the rechargeable device may increase in this way, and the user may touch the area due to the fact that the user is unaware of the excessive temperature of the area, thereby affecting the user experience.
Therefore, the over-temperature prompting method provided by the invention can be used for performing over-temperature prompting on the heating area of the chargeable device, so as to avoid that the user is unaware of the temperature of the over-temperature prompting area and touches the area when the temperature of the over-temperature prompting area is higher. For example, the chargeable device is a chargeable oral care device, such as a chargeable toothbrush, which is charged by wireless charging, and the charging coil is disposed at the bottom of the toothbrush handle, and during charging, the temperature of the bottom of the toothbrush handle may reach 45 degrees celsius due to the higher charging current. At the end of charging, the user may touch the area by not knowing that the bottom of the toothbrush handle has reached a high temperature of 45 degrees celsius, thereby affecting the user experience. Therefore, the over-temperature prompting method provided by the application can be adopted, when the temperature of the bottom of the toothbrush handle is too high, the user is prompted that the temperature of the area is too high, and therefore the situation that the user touches the area when the temperature of the over-temperature prompting area is higher because the user does not know the temperature of the over-temperature prompting area can be effectively avoided.
Referring to fig. 1, fig. 1 is a schematic flow chart of an over-temperature prompting method according to an embodiment of the present application; the over-temperature prompting method comprises the following steps:
step S100: and in the charging process, opening an over-temperature prompt according to a preset over-temperature condition.
In the step S100, the preset over-temperature condition includes: the temperature of the over-temperature prompting area of the chargeable device exceeds a first temperature threshold, or the charging time is longer than a preset temperature rise time. It should be noted that the value of the temperature-raising time period may be configured based on the environment where the rechargeable device is located and the ambient temperature.
Step S200: judging whether the charging of the chargeable device is finished; if the charging of the chargeable device is finished, closing the over-temperature prompt according to a preset stop condition;
in the above step S200, the preset stop condition includes: the temperature of the over-temperature prompting area is lower than a second temperature threshold, or the time length for stopping charging of the charging device is not less than the temperature reduction time length.
It can be understood that, in the implementation process, the temperature prompting method is used for prompting the user whether the over-temperature prompting area of the rechargeable device is in the over-temperature state or not, so that the problem that the user experience is influenced due to the fact that the user does not know the temperature of the over-temperature prompting area and touches the over-temperature prompting area when the temperature of the over-temperature prompting area is higher than that of other areas of the charging equipment can be effectively avoided.
It should be noted that the cooling time length is related to the temperature value of the over-temperature prompt area after the charging is finished, the second temperature threshold, and the heat attenuation coefficient, and specifically, in some optional embodiments, the calculation of the cooling time length includes the following steps:
the method comprises the following steps: acquiring a temperature value and a second temperature threshold value of the over-temperature prompt area after charging is finished;
step two: and calculating the temperature difference between the temperature value of the over-temperature prompting area and the second temperature threshold value after the charging is finished.
In the second step, the temperature difference is equal to a difference obtained by subtracting the second temperature threshold from the temperature value of the over-temperature prompting area after the charging is finished.
Step three: and obtaining the heat attenuation coefficient.
Step four: the cooling duration is obtained by dividing the temperature difference by the heat attenuation coefficient.
And in the first to fourth steps, the cooling duration can be calculated according to the temperature value of the over-temperature prompting area after the charging is finished, the second temperature threshold and the heat attenuation coefficient.
And judging whether the temperature of the prompt area exceeds a second temperature threshold value or not through the cooling time length. Specifically, when the charging ending time is longer than the cooling time, the temperature of the over-temperature prompting area is considered not to exceed the second temperature threshold. Whether the temperature of the prompt area exceeds the second temperature threshold value or not is judged through the cooling time length, and a corresponding module is not needed to be configured to monitor the temperature of the over-temperature prompt area in real time, so that the hardware cost and the power consumption of the method are saved.
In some optional embodiments, the values of the first temperature threshold, the second temperature threshold, and the thermal decay coefficient are configured based on the environment in which the chargeable device is located and the ambient temperature. The first temperature threshold and the second temperature threshold are determined according to the normal temperature of the environment where the chargeable device is located, and the first temperature threshold and the second temperature threshold may be the same or different. In a preferred embodiment, the values of the normal temperature and the thermal attenuation coefficient of the environment where the chargeable device is located change with the change of four seasons, and the values are specifically shown in table 1:
TABLE 1
| Month of the year | [3,5] | [6,8] | [9,11] | [12,2] |
| At normal temperature | 18 | 25 | 18 | 8 |
| k | 0.3 | 0.2 | 0.3 | 0.4 |
For example, in a specific embodiment, the chargeable device is charged in 6 months, and the charging device is charged, if the specific temperature value in the over-temperature prompting area after the charging is finished is measured to be 60 degrees celsius, the cooling time period is t, and may be determined to be 175 seconds, that is, the charging device controls to turn off the over-temperature prompting in the over-temperature prompting area after about 3 minutes after the charging is finished.
It should be noted that, the settings of the values of the first temperature threshold, the second temperature threshold and the thermal attenuation coefficient in the table are only exemplary, and in the actual value setting process, the settings may be adjusted according to the actual situation, and the settings of the values of the first temperature threshold, the second temperature threshold and the thermal attenuation coefficient in the table should not be construed as limiting the present invention.
Referring to fig. 2, fig. 2 is a schematic flow chart of an over-temperature prompting method in a preferred embodiment according to the present disclosure; in a preferred embodiment, the on or off of the over-temperature prompt is controlled by detecting the temperature of the over-temperature prompt area in real time, and the specific process is as follows:
step S1: and acquiring the temperature of the over-temperature prompt area.
In the step S1, the temperature of the over-temperature prompting area may be obtained in real time by using a temperature detection module.
Step S2: and judging whether the temperature of the over-temperature prompting area exceeds a first temperature threshold value.
If yes, go to step S3: and turning on an over-temperature prompt.
In the above steps S2-S3, specifically, the first temperature threshold is 1.4-1.6 times of the preset normal temperature, and the over-temperature prompt is turned on if the temperature of the over-temperature prompt area exceeds 1.4-1.6 times of the preset normal temperature. The preset normal temperature is specifically as described above, and this embodiment is not described again.
Step S4: and acquiring the temperature of the over-temperature prompting area.
Step S4 is similar to step S1, and the same temperature detection module can be used to obtain the temperature of the over-temperature prompt area in real time. It should be noted that the step S4 of acquiring the temperature of the over-temperature prompting area occurs after the charging of the chargeable device is finished. As shown in fig. 2, the dotted line box represents the steps performed after the charging of the chargeable device is completed.
Step S5: and judging whether the temperature of the over-temperature prompting area is lower than a second temperature threshold value.
If so, go to step S6: and closing the over-temperature prompt.
In the above-mentioned realization process, through opening and closing of the temperature control excess temperature suggestion that acquires excess temperature suggestion region, consequently, when excess temperature suggestion region temperature is too high, through opening excess temperature suggestion user, and then close excess temperature suggestion when excess temperature suggestion region temperature is low second temperature threshold value, through opening and closing of excess temperature suggestion, the suggestion user is in order to avoid the user to touch this region because of not knowing the circumstances.
Referring to fig. 3, fig. 3 is a schematic flow chart of an over-temperature prompting method in another preferred embodiment provided in the present application; in another preferred embodiment, the over-temperature prompting area is controlled to turn on the over-temperature prompting by the charging time of the chargeable device, and the specific process is as follows:
step S10: and acquiring the charging time length.
In the above step S10, in an alternative embodiment, the preset charging time period is generally 10% of the total time period of the conventional full charge. Specifically, for example, if the total time period for charging a certain chargeable device is 5 hours, the preset charging time period is 0.5 hours.
Step S20: and judging whether the charging time is longer than a preset temperature rise time.
If yes, go to step S30: and turning on an over-temperature prompt.
Step S40: the time period for which the chargeable device stops charging is obtained.
As shown in fig. 3, the dotted line box represents the steps performed after the charging of the chargeable device is stopped.
Step S50: and judging whether the charging stop time of the chargeable device is not less than the cooling time.
If not, go to step S60: and closing the over-temperature prompt.
In the implementation process, the opening and closing of the over-temperature prompt are controlled by time, so that the temperature of the over-temperature prompt area does not need to be detected by the temperature detection module, and the configuration cost of the device is saved. In addition, the temperature detection module is used for detecting and acquiring the temperature, the temperature detection module can influence the detection of the temperature of the over-temperature prompt area due to self heating, and the mode of controlling the on and off of the over-temperature prompt by time is adopted, so that the influence of self heating of the temperature detection module is avoided, and the prompt accuracy is improved.
In a preferred embodiment, the obtaining of the temperature value in the over-temperature prompting area after the charging is finished includes, but is not limited to, the following two ways:
in the first mode, the temperature of the over-temperature prompting area is acquired in real time through a temperature detection module arranged in the over-temperature prompting area;
in the second mode, the temperature values of the corresponding over-temperature prompt areas under different cooling time lengths are calculated in advance and configured in a data table of a database.
