Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, unless explicitly specified and limited otherwise, the terms "mounted," configured to, "" engaged with, "" connected to, "and the like are to be construed broadly, and may be, for example," connected to, "wall-mounted," connected to, removably connected to, or integrally connected to, mechanically connected to, electrically connected to, directly connected to, or indirectly connected to, through an intermediary, and may be in communication with each other between two elements, as will be apparent to those of ordinary skill in the art, in view of the detailed description of the terms herein.
Referring to fig. 1, the invention further provides a water outlet device, which comprises a water outlet device body and an induction device. The sensing device comprises two sensitivities, namely high sensitivity and low sensitivity, when the sensing device is switched to the high sensitivity, at least one of a trigger threshold and a scanning period of the sensing device is reduced, in the embodiment, the trigger threshold can be reduced to 1.024V, or the scanning period is reduced to 0.25ms; when the sensing device switches to low sensitivity, at least one of the trigger threshold and the scan period of the sensing device is increased, in this embodiment, the trigger threshold may be increased to 2.048V, or the scan period may be increased to 0.5ms. In order to achieve better effect, the trigger threshold and the scanning period can be adjusted at the same time, and the adjustment can be performed according to actual conditions. Or the purpose of increasing or decreasing the induction sensitivity can be achieved by modifying other parameters. The sensing device is internally provided with a self-adaptive sensing detection method, which comprises the following steps:
1) Decomposing one day into N time periods, dividing the time period into 24 time periods according to an hour unit in the embodiment, and recording the induction triggering times N in each time period; n can be set as a threshold according to actual needs, in this embodiment, a period of time n being greater than or equal to 5 is defined as a period of time for high frequency use, and a period of time n <5 is defined as a period of time for low frequency use; as a simple alternative to this embodiment, the division may be performed in units of 2 hours or in units of half an hour. The simple replacement of this embodiment is not described in detail.
2) During periods of high frequency use, the sensing device is at high sensitivity; during periods of low frequency use, the sensing device is at low sensitivity; thus, the high sensitivity is kept in a high-frequency use time period to ensure the user experience; the sensitivity is reduced in the low-frequency use time period, the probability of false triggering is reduced, and good experience is brought to users. When the sensing device is used at a high frequency, in order to facilitate the use of a user, the sensing device can be set to judge that effective sensing triggering is performed after receiving a reflected signal in 1 scanning period, so that sensing is performed only by 0.25ms, and the use of the sensing device is very convenient for the user.
In order to further reduce the false touch rate in the low frequency use period, the reflected signal is received for M consecutive scan periods in the low frequency use period to determine that the sensing trigger is valid. In this embodiment, M is 4, so that the duration is about 2ms to trigger sensing. Therefore, when the winged insects, the crawlers or the pets pass through the sensing window at night, the sensing signal can not be triggered.
In addition, if the user effectively triggers the sensing signal in the time period of the original low-frequency use, the sensing signal is troublesome if the user still keeps in a state of triggering the threshold value and the scanning period is high, and if the user needs to trigger the sensing signal for a plurality of times because the sensing sensitivity is low. Therefore, in order to solve this problem, after the effective sensing is triggered once in the low frequency use time period, the trigger threshold and the scanning period are restored to the values in the high frequency use time period, and the setting time can be continued, so that the user can be sensitive when the sensing signal needs to be triggered again in the setting time, and the original state of the low frequency use time period is restored after the setting time is exceeded. In this embodiment, the setting time is M, the setting number of times of effective induction is I, t is the interval time after the last effective triggering, when i=0, that is, when the sensing device is used for the first time, the sensing device is in a low sensitivity state at this time, and the sensing device needs to receive the reflected signals in M continuous scanning periods to judge that effective induction triggering is performed; after effective induction triggering, i=1, when a user needs to use again, the induction device receives a reaction signal, when the interval time t from the last effective triggering of the reaction signal is less than m, the induction device is switched into a high-sensitivity state, the user can trigger the reaction signal without carrying out a plurality of scanning periods, when the interval time t +.m from the last effective triggering of the reaction signal is received by the induction device, the counter of the induction device clears I, i=0, and the induction device is switched into a low-sensitivity state. The setting can meet the demands of users in the low frequency band, and can prevent the false touch in the low frequency band. In order to be more humanized, the service time of high sensitivity is prolonged, after each effective triggering, the sensing device clears t and rechems, and the sensing device can be guaranteed to be in a high-sensitivity state in m time of the last effective triggering.
The scanning period M and the setting time M can be modified according to the needs, so as to meet different needs of users, and the scanning period M and the setting time M belong to simple replacement of the embodiment and are not repeated.
Finally, since the number of times the user needs to trigger the sensing signal is different in the same period of time in different seasons, such as summer and winter, it is possible that the evening in winter is a period of low frequency use and the summer is a period of high frequency use. Thus, step 1 is performed again at intervals to update the period of high frequency use and the period of low frequency use.
In this embodiment, the water outlet device body is a faucet, which may be a kitchen faucet or a basin faucet.
The foregoing is only a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any person skilled in the art will be able to make insubstantial modifications of the present invention within the scope of the present invention disclosed herein by this concept, which falls within the actions of invading the protection scope of the present invention.
