[0033] The present invention is further described below through specific implementation methods.

[0034] See also Figures 1 to 8 A water treatment system includes a scale inhibitor 10, a filter 20, a pressure boosting device 30, and a control valve 40. The scale inhibitor 10 is used to physically inhibit scale in the input water. The scale inhibitor 10, the control valve 40, and the pressure boosting device 30 are connected in sequence to form a main waterway. The filter 20 is connected to the control valve 40, and the filter 20 is used to filter impurities in the water. The control valve 40 is used to control the system in different operating modes according to the water pressure or flow rate of the main waterway, including a filtering mode and a direct-through mode. In the filtering mode, the control valve 40 is connected to the filter 20 so that it is connected in series between the output end of the scale inhibitor 10 and the input end of the pressure boosting device 30, and the water flows through the scale inhibitor 10, the filter 20, and the pressure boosting device 30 in sequence before being output. In the direct-through mode, the control valve 40 closes the filter 20 so that the output end of the scale inhibitor 10 is directly connected to the input end of the pressure boosting device 30, and the water flows through the scale inhibitor 10 and the pressure boosting device 30 before being output.

[0035] The control valve 40 can be a waterway reversing valve, which can be manually or electrically controlled. In this embodiment, taking the electrically controlled waterway reversing valve as an example, the control valve 40 includes a valve core 41, a valve body 42, and a motor 43. The valve body 42 is provided with multiple water inlets and outlets for connecting to the scale inhibitor 10, the filter device 20, and the booster 30. The valve core 41 is installed in the valve body 42 and can be controlled to connect the scale inhibitor 10 and the booster 30 directly, or to connect the filter device 20 in series between the output end of the scale inhibitor 10 and the input end of the booster 30; the output shaft of the motor 43 is connected to the control valve core 40 to achieve switching.

[0036] Specifically, valve body 42 is provided with a first water inlet 44, a second water inlet 45, a first water outlet 46, and a second water outlet 47. The first water inlet 44 is connected to the output of the scale inhibitor 10, the first water outlet 46 is connected to the water inlet of the filter 20, the second water inlet 45 is connected to the water outlet of the filter 20, and the second water outlet 47 is connected to the input of the booster 30. In filtering mode, motor 43 controls the valve 40 to drive the first water inlet 44 and the second water inlet 45 to connect to the corresponding first water outlet 46 and second water outlet 47, respectively. This connects the output of the scale inhibitor 10 to the water inlet of the filter 20, and the water outlet of the filter 20 to the input of the booster 30. In the direct-through mode, the motor 43 controls the valve core 40 to drive the first water inlet 44 to connect to the second water outlet 47 and close the first water outlet 46 and the second water inlet 45. At this time, the output end of the scale inhibition device 10 is directly connected to the input end of the boosting device 30, and the water inlet and outlet ends of the filter device 20 are closed.

[0037] In this embodiment, the filter device 20 may include more than one filter unit 21, and the multiple filter units 21 are arranged in series or in parallel. The number of filter units 21 can be set according to actual needs. Figure 7 In the figure, two parallel filter units 21 are taken as an example. The water inlet and outlet ends of the two filter units 21 are connected to the control valve 40. The filter unit 21 is also provided with a sewage discharge end, and the sewage discharge ends of the two filter units 21 are connected.

[0038] In this embodiment, in order to separately control the working state of each filter unit 21, including the filtering state, sewage discharge state, etc., the filter device 20 further includes an electric control valve group for controlling the water inlet end, water outlet end and sewage discharge end of each filter unit 21. Figure 8 The filtering device 20 also includes at least two first electrically controlled valves 22, at least two second electrically controlled valves 23 and at least two third electrically controlled valves 24; the at least two first electrically controlled valves 22 are respectively used to control the opening or closing of the water inlet ends of at least two filtering units 21, the at least two second electrically controlled valves 23 are respectively used to control the opening or closing of the water outlet ends of at least two filtering units 21, and the at least two third electrically controlled valves 24 are respectively used to control the opening or closing of the sewage discharge ends of at least two filtering units 21.

[0039] Taking the two filter units 21 in the figure as an example, when the first and second electrically controlled valves 22 and 23 are controlled to be open and the third disconnect valve is closed, the filtering function of the two filter units 21 is activated. When the first and third electrically controlled valves 22 and 24 are controlled to be open and the second electrically controlled valve 23 is closed, the forward flushing function of the two filter units 21 is activated, water flows out from the sewage discharge end, and at the same time, the retained materials of the two filter units 21 are taken away. When one of the first electrically controlled valves 22, two of the second electrically controlled valves 23, and one of the third electrically controlled valves 24 are controlled to be open, and the other first electrically controlled valve 22 and the other third electrically controlled valve 24 are closed, the backwashing function of one of the filter units 21 is activated, water flows out from the sewage discharge end, and the retained materials of the filter unit 21 are taken away. The backwashing function operation of the other filter unit 21 is similarly operated.

[0040] In this embodiment, filter unit 21 utilizes a filter element comprised of PP cotton and activated carbon fiber, or alternatively, an ultrafiltration membrane and activated carbon fiber, which can be configured based on actual needs. The filter element intercepts and adsorbs impurities such as rust, silt, and colloids from the water, while the activated carbon fiber removes discoloration, odor, and residual chlorine from the tap water. The filter element in filter device 20 is replaceable and can be replaced when its lifespan reaches its limit.

[0041] The scale inhibition device 10 is provided with scale inhibition materials to achieve physical scale inhibition. It adopts a central water softener. The scale inhibition materials inside are composed of metal elements with different electronegativity, and are formed into a columnar crystal structure with consistent orientation and neat arrangement through a special process. This structure enables the catalyst material to release free electrons to the fluid medium, thereby causing the fluid medium to produce a polarization effect. This polarization effect can effectively prevent and remove scale formed by calcium and magnesium ions in the water, thereby achieving a purely physical scale inhibition and descaling effect. A fourth electrically controlled valve 11 is provided at the input end of the scale inhibition device 10. The fourth electrically controlled valve 11 adopts an electric ball valve, which is used to control the opening or closing of the water inlet at the input end of the scale inhibition device 10.

[0042] The booster device 30 utilizes a variable frequency booster pump, serving as the system's pressure-stabilizing water supply unit. Its function is to deliver filtered, purified water at a constant pressure to each water point. The booster device 30 also activates boosting when the input water pressure falls below a set value. Internally, the booster device 30 is equipped with a water flow switch, a pressure transmitter, and a variable frequency membrane assembly. It incorporates features such as water shortage protection, pressure limiting protection, and variable frequency water supply. It automatically adjusts the output pressure (motor power) based on the number of taps open at each water point and the water pressure, ensuring stable water supply pressure.

[0043] This embodiment also includes a flow sensor 50 or a pressure sensor, which is a water volume detection unit in the main water channel. It is installed at the output end of the boosting device 30 to detect the flow rate or water pressure of the main water channel. It can also be installed at the input end of the boosting device 30 or other suitable locations. In the figure, taking the flow sensor 50 as an example, its impeller is attached with a Hall element, which will output a signal when it rotates. The output signal can be converted by a circuit and used to count the water flux in the pipeline. Based on the detected signal, it can be determined whether the filter element has reached its life limit or whether there is a water leak. For example, when the flow sensor 50 counts that the water flow has reached the set value and the flow rate is significantly smaller, the system will issue a filter element replacement reminder and notify the user at the same time.

[0044] This embodiment also proposes a whole-house water treatment product, see Figure 9-10 The water treatment system includes a housing 60 and the above-mentioned water treatment system. The housing 60 is provided with a water inlet 61, a sewage outlet 62, and a water outlet 63. A storage space is provided within the housing 60. The scale inhibitor 10, the filter 20, the booster 30, and the control valve 40 are installed in the storage space within the housing 60. The input end of the scale inhibitor 10 is connected to the water inlet 61, the sewage outlet of the filter 20 is connected to the sewage outlet 62, and the output end of the booster 30 is connected to the water outlet 63. The sewage outlet 62 is also provided with a solenoid valve 67 to open or close the sewage outlet 62.

[0045] For actual installation, see Figure 10 , also includes a water inlet pipe 64, a clean water pipe 65, and a drain pipe 66. One end of the water inlet pipe 64 can be connected to tap water, and the other end is connected to the water inlet 61. One end of the clean water pipe 65 is connected to the water outlet 63, and the other end can be connected to different water points. The drain pipe 66 is connected to the sewage outlet 62.

[0046] The working principle of the water treatment system and whole-house water treatment product of this utility model is as follows:

[0047] When the filtration mode is turned on, the control valve 40 controls the connection to the filter device 20, and the scale inhibition device 10, the filter device 20 and the boosting device 30 are connected in series in sequence. The tap water is scale-inhibited by the scale inhibition device 10, and then enters the filter element of the filter device 20 for filtration and purification to obtain clean water. If the clean water pressure is insufficient, it will be pressurized by the boosting device 30 and then flow out from the water outlet 63 to the water use point.

[0048] When the direct-through mode is turned on, the control valve 40 closes the filter device 20, and the output end of the scale inhibition device 10 is directly connected to the input end of the boosting device 30. The tap water is scale-inhibited by the scale inhibition device 10 and directly enters the boosting device 30, and then flows out from the water outlet 63 to the water use point.

[0049] In practice, when a filter reaches its lifespan, it no longer purifies the water. Instead, trapped harmful substances slowly precipitate out, contaminating the water source. Because water flow decreases at the end of a filter's lifespan, it can affect water pressure at points throughout the house and may cause frequent starts and stops of the variable frequency booster pump in the system's pipelines.

[0050] Therefore, when the purified water volume reaches the rated total purified water volume of the filter device 20 and the flow rate or pressure of the main water channel is less than or equal to the set value, the control valve 40 automatically switches the water channel, closing the connection between the filter device 20 and the main water channel. The tap water then bypasses the filter element and directly enters the pressurized component, thereby removing the expired filter device 20 from the system and protecting the water quality of the entire house. In addition, when a water leak is detected by the flow sensor or pressure sensor, the system activates the water leak protection function, controlling the electric ball valve to close and cut off the water supply.

[0051] The terms "first" and "second" appearing in the present invention are only for the convenience of description to distinguish different components with the same name, and do not indicate a sequence or primary and secondary relationship.
