The hardware structure of this embodiment is basically the same as that of the first embodiment, except that the automatic water outlet control unit correspondingly controls the water outlet end of the automatic water outlet control unit to change the water outlet strategy according to the first group of sensing signals or the second group of sensing signals.

Specifically, in this embodiment, the outlet strategy is changed to increase the flow rate of the outlet end and decrease the flow rate of the outlet end (the opening and closing of the water flow can be controlled by the faucet handle and/or the infrared sensor), but not limited thereto, and of course, in other embodiments, the automatic outlet control unit can correspondingly control the outlet end thereof to change other outlet strategies different from the first embodiment and the second embodiment according to the first set of sensing signals or the second set of sensing signals.

EXAMPLE III

Most parts of the present embodiment are the same as those of the first embodiment, and the main differences are as follows: as shown in fig. 3, the number of the sensing marks 41 of this embodiment is 3, which are respectively an upper sensing mark 411, a middle sensing mark 413, and a lower sensing mark 412, where the middle sensing mark 413 is used to assist the automatic water outlet control unit to control the water outlet end thereof to change the water outlet strategy, and for example, to assist in determining whether the pull-out hose 2 is pulled out to a set length or retracted to the original position, specifically, when the hall sensor senses the upper sensing mark 411, the middle sensing mark 413, and the lower sensing mark 412 and outputs three spaced sensing mark moving signals to the control board of the water outlet control unit, the water outlet control unit determines that the pull-out hose 2 is pulled out to the set length or retracted to the original position. But is not limited to this and in some embodiments, the sense flag may be used for other control actions as well.

Of course, in other embodiments, the total number of the sensing marks 41 can be more than 4, so as to realize more complicated water outlet strategies.

Example four

In this embodiment, the upper and lower sensing marks are both circular structures, hereinafter referred to as upper and lower demagnetizing rings 511 and 512, and are fixedly sleeved on the pull hose 2, so that the fixing is easy, the fixing strength is good, and the pull hose is not easy to fall off. However, the present invention is not limited thereto, and in other embodiments, the inductive label 51 may also have other structures, such as a strip structure, a circular-arc sheet structure, and the like.

In this embodiment, the upper and lower inductive marks are respectively an N pole 611 and an S pole 612 of the magnet, but in other embodiments, the upper and lower inductive marks may also be respectively an S pole and an N pole of the magnet.

Most parts of the present embodiment are the same as those of the seventh embodiment, and the main differences are that: a drawing induction structure of the vector signal is adopted to replace a drawing induction structure of the switching value signal; that is, the sensing flag of the present embodiment is a vector sensing flag, and the sensor is a vector sensor.

Specifically, in this embodiment, go up the response sign and realize by the chromatic circle of two different colours respectively with lower response sign, two chromatic circles set up the pull hose outer peripheral face along the length direction interval of pull hose, and the setting for of the interval size of two chromatic circles can adjust the change according to the needs that the in-service use experienced, and this interval size can influence and decide the gondola water faucet and take out how long distance to switch out water control mode.

The photoelectric sensing sensor can sense the color difference of going up the response sign and responding to the sign down to distinguish and be the response sign or respond to the sign down, can judge according to the response order of last response sign and response sign down that the gondola water faucet is taken out or fall back and reset, control the switch and/or the aperture of solenoid valve better, avoid the error control, improve and use experience.

The photoelectric sensing sensor can be realized by selecting a photoelectric sensing sensor with high-sensitivity analog quantity output and then connecting the photoelectric sensing sensor with an ADC (analog-to-digital converter) module, and the automatic water outlet control unit distinguishes an upper sensing identifier and a lower sensing identifier according to the numerical value of the ADC module, but the automatic water outlet control unit is not limited to the above.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
