As described in the background, in the conventional multi-mode water supply apparatus, two kinds of water outlet taps are generally configured to satisfy the needs of two different water outlet functions. Correspondingly, holes are reserved when the novel lamp is installed, so that the cost is increased, and the overall attractiveness is affected. If two water outlet faucets are not configured, the situation of mixing with the residual water in the previous mode can occur when the user fetches pure water in the pure water mode after fetching pure water in the domestic water mode, and the user is inconvenienced in drinking water.

Based on the water mixing problem of the multi-mode water purifying equipment, the water outlet faucet is provided with a water channel structure which is set to be a multi-channel conveying mode, so that water of different water types corresponds to the special water outlet channel, and the drinking experience of users is met.

In an exemplary embodiment, as shown in fig. 1 and 2, a water outlet faucet is provided, and includes a faucet main body 110, a controller 120, a flow collection device 130, and at least two water outlet channels disposed inside the faucet main body 110, wherein each water outlet channel includes an independent water inlet and an independent water outlet, and a switch device is connected in series to each water outlet channel; different water outlet channels are used for outputting water of different water use types; the flow acquisition device 130 is used for acquiring the water outlet flow data of each water type and feeding the water outlet flow data of each water type back to the controller 120; the controller 120 is configured to control any one of the switching devices to enter a conducting state according to the water intake command, and control the switching state of the switching device according to the water flow data of each water type, so as to quantitatively output water of different water types to a user.

Specifically, at least two water outlet channels arranged inside the tap main body 110 are water channels for independently discharging water, which can be understood that the water flows in each water outlet channel are not collected and mixed inside the tap main body 110 and comprise independent water inlets, water delivery pipelines and water outlets. The water inlets of the water outlet channels can be respectively connected with a plurality of water outlets of the multi-mode water purifying device to obtain water of different water types, and the water of different water types is output to a user for use through the water delivery pipelines and the water outlets of the corresponding water outlet channels.

It will be appreciated that the number of outlet channels provided in the outlet tap may be matched to the number of water usage types available from the multi-mode water purification apparatus to which it is connected. Meanwhile, the specific type of water which can be output by the water outlet faucet can also be determined according to the type of water which can be provided by the multi-mode water purifying device, for example, the type of water can be unfiltered tap water, preliminarily filtered pure water, completely filtered pure water, mineralized water subjected to mineralization treatment and the like. Correspondingly, in the case that the water type includes all of the above water types, the faucet body 110 may be provided therein with four water outlet passages, respectively applied to output unfiltered tap water, primarily filtered purified water, completely filtered purified water, and mineralized water subjected to mineralization treatment. Taking the faucet shown in fig. 2 and 3 as an example, it includes a purified water outlet channel 140 and a purified water outlet channel 150, the purified water outlet channel 140 includes a purified water inlet 141 and a purified water outlet 142, and the purified water outlet channel 150 includes a purified water inlet 151 and a purified water outlet 152.

Further, the switch device connected in series on each water outlet channel can receive the control signal from the controller 120, so as to control the on-off of each water outlet channel. For example, when the controller 120 determines that water of a certain water type needs to be output according to the water intake instruction, the controller outputs a control signal to the switching device connected in series on the water outlet channel corresponding to the water type, so that the switching device is in a conducting state, and the water of the water type is output to the user. Correspondingly, after the controller 120 judges that water taking is finished, a control signal is output to the switching device connected in series on the water outlet channel corresponding to the water type again, so that the switching device is in a closed state, and the output of the water type is stopped. Taking the water tap shown in fig. 2 as an example, a water purifying switch device 143 is connected in series to the purified water outlet channel 140, and a purified water switch device 153 is connected in series to the purified water outlet channel 150.

The water way is controlled to be on or off by the pilot electromagnetic valve, and the valve body can only be closed after failure, so that the water leakage problem can not occur.

Further, the flow collection device 130 is used for realizing flow monitoring, that is, for collecting the water flow data of each water type, and feeding the water flow data of each water type back to the controller 120, so that the controller 120 can realize the quantitative water outlet function. The flow collection device 130 may be disposed in the multi-mode water purification apparatus, for example, at a plurality of water outlets or in a corresponding water channel of the multi-mode water purification apparatus.

The expression form of the water flow rate data is not limited, and may be, for example, actual flow rate data in a unit time, or the number of pulse signals collected in a unit time.

In one exemplary embodiment, the flow acquisition device 130 is implemented using a hall-type flow meter. Specifically, as shown in fig. 4, the hall flowmeter includes a hall sensor 131 and a magnetic impeller 132, the magnetic impeller 132 is disposed inside a pipeline where flow is required to be collected, the hall sensor 131 is disposed at a corresponding position outside the pipeline, the magnetic impeller 132 is connected with the hall sensor, and the hall sensor 131 is connected with the controller 120. When water flows through the pipeline, the built-in impeller 132 with the magnet rotates to cut the magnetic induction line to generate a Hall effect, and the external Hall sensor 131 outputs a pulse signal to the controller 120 after sensing the Hall effect. The controller 120 can convert the number of the received pulse signals to obtain corresponding water flow data.

The controller 120 is illustratively a control center of the faucet, and may be a control chip or a control circuit board provided in the faucet body 110, or may be an external control system implemented based on wireless communication.

The controller 120 can intelligently calculate the water outlet time according to the received water outlet flow data and the water intake amount set by the user in the water intake instruction, and further control the switch device to enter the off state under the condition that the timing reaches the corresponding water outlet time, so as to quantitatively output water of different water types to the user. It can be understood that quantitative water taking is realized through accurate flow acquisition, the situation that a user cannot acquire the set water taking amount through a quantitative water taking function under the complex factors of different pressure working conditions, insufficient water supply or service life of a filter element can be avoided, and the water taking experience of the user is effectively improved.

Specifically, the number of the flow collection devices can be set to be matched with the number of the water outlet channels, and then the corresponding flow collection devices can be connected in series in each water outlet channel, so that collection of water outlet flow data of water type water flowing through the water outlet channel is realized. It will be appreciated that the water outlet flow data collected herein corresponds to the data of the water outlet channel corresponding to the single water outlet faucet device, rather than the overall water outlet flow data of the water outlet faucet included in the plurality of terminal water outlet devices. Taking the water tap shown in fig. 5 as an example, a purified water flow collection device 144 is connected in series to the purified water outlet channel 140, and a purified water flow collection device 154 is connected in series to the purified water outlet channel 150.
