[0086] During use of the water outlet device of the embodiment of the present invention, when the filter screen 2 is clogged, the acid generating module 3 can generate acid and release it toward the filter screen 2 , thereby dissolving scale in the filter screen 2 through the acid.

[0087] Furthermore, since the acid can dissolve scale, it can prevent the scale from being unable to separate from the filter 2 due to large particles, thereby overcoming the defect of poor descaling effect of the water outlet device in the related art.

[0088] In addition, the acid generating module 3 can also dissolve the scale on the wall of the water pipe 1, thereby restoring the flow capacity of the water pipe 1 and avoiding local electrochemical corrosion caused by the accumulation of scale.

[0094] Through such an arrangement, when descaling is required, the salt storage chamber 302 can release salt to the acid collection chamber 303, and the positive electrode and the negative electrode can electrolyze the salt solution and generate gas. The gas enters the acid collection chamber 303 to generate an acid solution, and the acid solution enters the water pipe 1 and dissolves the scale on the filter 2.

[0103] In one embodiment, the water pipe 1 includes an inlet pipe section 101 and a filter pipe section 102, the filter screen 2 is arranged in the filter pipe section 102, and along the water flow direction in the water pipe 1, the inlet pipe section 101 is connected to the upstream of the filter pipe section 102, and the water outlet device also includes a first three-way valve 4, a first branch pipe 5 and a first water pump 6.

[0104] The first three-way valve 4 has a first port 401, a second port 402, and a third port 403. The first port 401 is connected to the water inlet pipe section 101, and the second port 402 is connected to the filter pipe section 102.

The first water pump 6 is located in the first branch pipe 5 and can drive the acid in the acid collection chamber 303 to flow to the filter 2.

[0105] With such an arrangement, when the water outlet device operates normally, the first port 401 and the second port 402 can be opened, thereby allowing water to flow through the water inlet pipe section 101 into the filter pipe section 102 .

[0106] When descaling is required, the third port 403 and the second port 402 can be opened, thereby allowing the first water pump 6 to drive the water in the acid collection chamber 303 into the filter pipe section 102 of the water pipe 1 .

[0107] In addition, the first branch pipe 5 can also allow the water in the water pipe 1 to enter the acid liquid collection chamber 303 .

At this time, the alkaline solution in the alkali solution collecting chamber 307 enters the water pipe 1, neutralizes the acidic liquid in the water pipe 1, and is discharged through the water outlet 1002 of the water pipe 1, thereby neutralizing the acid generated by the acid generating module 3, and avoiding the discharge of acid to pollute the environment.

Through this arrangement, the first separator 304 and the second separator 308 have multiple functions, which helps to reduce the number of parts in the acid generating module 3, thereby making the structure of the acid generating module 3 more compact and helping to simplify the assembly process of the acid generating module 3.

[0135] In one embodiment, the first separator layer 304 , the second separator layer 308 , and the third separator layer 311 each include a layer body 319 and a cover body.

[0136] Taking the first separation layer 304 as an example, a first guide cavity 3044 is provided on the layer body 319 , and a cover body is provided on the first guide cavity and is detachably connected to the layer body 319 .

[0139] In one embodiment, the water outlet device further includes a water flow sensor 11 , which is connected to the water pipe 1 downstream of the filter 2 and is used to detect the water flow in the water pipe 1 .

[0140] By such a setting, the water flow rate with the highest water flow rate and frequency in the water pipe 1 during the user's water use time period is defined as the normal value. When the water flow rate monitored by the water channel sensor is greatly reduced and the water outlet device operates normally without reporting a fault, the control module can determine that the pipeline is blocked, thereby switching the water outlet device to the descaling state.

[0141] Among them, the control module may include a programmable logic control component (such as a PLC or CPU), a memory, and electronic components connected to the programmable logic control component, etc., which are well known to those skilled in the art and will not be described in detail here.
