Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and all other embodiments obtained by those skilled in the art without any inventive work are within the scope of the present invention.

Furthermore, the terms "first" and "second" 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, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like, are used in a broad sense, and for example, "connected" may be a wall-mounted connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection through an intermediate medium, and a communication between two elements, and those skilled in the art will understand the specific meaning of the terms in the present invention specifically.
Referring to fig. 1, the present invention further provides a water outlet device, which includes a water outlet device body and an induction device. The sensing device comprises two sensitivities, 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 can be reduced to 0.25ms; when the sensing device is switched to low sensitivity, at least one of the trigger threshold and the scanning period of the sensing device is increased, in this embodiment, the trigger threshold may be increased to 2.048V, or the scanning 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 carried out according to actual conditions. Alternatively, other parameters may be modified to increase or decrease the sensitivity of the sensor. The induction device is internally provided with a self-adaptive induction detection method, which comprises the following steps:
1) Dividing one day into N time periods, in this embodiment, dividing the time periods into 24 time periods according to one hour as a unit, and recording the number N of times of induction triggering in each time period; n can set a threshold value according to actual needs, in the embodiment, a time period in which n is greater than or equal to 5 is defined as a time period in which high frequency is used, and a time period in which n is less than 5 is defined as a time period in which low frequency is used; as a simple alternative to this embodiment, the division may also be performed in units of 2 hours or half an hour. Which belongs to the simple replacement of this embodiment, and will not be described again.
2) During periods of high frequency use, the induction device is at high sensitivity; during periods of low frequency use, the sensing device is at low sensitivity; therefore, the high sensitivity is kept in a high-frequency use time period to ensure the user experience; sensitivity is reduced in a low-frequency use time period, the probability of false triggering is reduced, and good experience is brought to a user. When the induction device is used in a time period with high frequency, the induction device can be set to receive 1 scanning period and receive a reflection signal to judge that the reflection signal is effective induction triggering, and thus induction is triggered only by 0.25ms, and the induction device is convenient for a user to use.
In order to further reduce the false triggering rate in the low-frequency use time period, the effective induction triggering is judged only when the reflected signals are received in continuous M scanning periods. In this embodiment, M is 4, which requires a duration of about 2ms to trigger sensing. Therefore, when the winged insects, the reptiles 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 originally low-frequency use, if the user still keeps the state of high triggering threshold and scanning period, if the user needs to trigger the sensing signal for many times, because the sensing sensitivity is low, the user is troublesome. Therefore, in order to solve the problem, after the induction triggering is effectively performed once in the time period of low-frequency use, the triggering threshold and the scanning period are recovered to the values in the time period of high-frequency use, and the set time can be continued, so that the user can feel sensitive when needing to trigger the induction signal again in the set time, and the original state of the time period of low-frequency use is recovered after the set time is exceeded. In this embodiment, the time is set to M, I is set to the number of times of effective sensing, t is the interval time from the last effective triggering, when I =0, that is, when the sensor is used for the first time, the sensor is in a low-sensitivity state at this time, and the sensor needs to receive the reflected signal for M consecutive scanning cycles to determine that the sensor is effective sensing triggering; when effective induction triggering is carried out, I =1, when a user needs to use the induction device again, the induction device is switched to a high-sensitivity state when the induction device receives a reaction signal and the interval time t from the last effective triggering is less than m, the user does not need to carry out scanning cycle for many times to trigger the induction device, when the induction device receives the reaction signal and the interval time t from the last effective triggering is more than or equal to m, a counter of the induction device clears I, I =0, and the induction device is switched to a low-sensitivity state. The setting both can satisfy the demand of user when the low band uses like this, can prevent again that the mistake when the low band from touching. In order to be more humanized and prolong the service time of high sensitivity, after each effective trigger, the sensing device clears t and times again, so as to ensure that the sensing device can be ensured to be in a high sensitivity state within m time of the last effective trigger.
The scanning period M and the setting time M can be automatically modified as required to meet different requirements of users, and the method belongs to simple replacement of the embodiment and is not repeated.
Finally, since the number of times that the user needs to trigger the sensing signal in the same time period is different in different seasons, such as summer and winter, there is a possibility that the evening in winter is a time period of low frequency use, and the summer is a time period of high frequency use. Therefore, step 1 is re-executed once every certain period of time to update the periods of high frequency use and 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 above description 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 can make insubstantial changes in the technical scope of the present invention within the technical scope of the present invention, and the actions infringe the protection scope of the present invention are included in the present invention.
