For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] The present invention is further described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0045] See also Figure 1 and Figure 2 The present embodiment provides a water purification device, which includes a water volume adjustment knob 10, a metering device, a water circuit control valve and a controller. The water volume adjustment knob 10, the water circuit control valve and the metering device are all electrically connected to the controller. The water volume adjustment knob 10 can be rotated and stopped at several quantitative water outlet positions, and the quantitative water outlet positions correspond to the quantitative water outlet volumes one by one.

[0046] The controller is used to control the water circuit control valve to open when the water volume adjustment knob 10 stops at the quantitative water outlet position (a water volume pointer 11 can be set on the water volume adjustment knob 10 to determine the current quantitative water outlet position by using the indication direction of the water volume pointer 11; in addition, an identification can be set on the panel of the water purification device for installing the water volume adjustment knob, so that the identification can be used as a basis for judging what kind of quantitative water outlet volume the current indication direction of the water volume pointer 11 represents); the controller is used to convert the parameters measured by the metering device into the actual water outlet volume after the water circuit control valve is opened, and is used to control the water circuit control valve to close when the actual water outlet volume reaches the quantitative water outlet volume corresponding to the quantitative water outlet position where the water volume adjustment knob 10 is located.

[0047] It should be noted that the water circuit control valve in this embodiment may include a water inlet control valve 40 and a water outlet control valve, both of which comply with the opening and closing conditions of the above-mentioned water circuit control valve.

[0048] See also Figure 1 and Figure 2 Based on the above structure of the water purification device provided in this embodiment, this embodiment also provides a control method, which includes the following steps:

[0049] The control method comprises:

[0050] Step a, when the water volume adjustment knob 10 is rotated to stop at the quantitative water outlet position, the controller controls the water circuit control valve to open;

[0051] Step b, when the water circuit control valve is opened, the controller controls the metering device to start metering, and converts the parameter measured by the metering device into the actual water output volume after the water circuit control valve is opened;

[0052] Step c: when the actual water output volume reaches the quantitative water output volume corresponding to the current quantitative water output position of the water volume adjustment knob 10, the controller controls the water circuit control valve to close, completing the quantitative water intake.

[0053] When quantitative water intake is required, the water volume adjustment knob 10 can be rotated so that the water volume adjustment knob 10 stops at the quantitative water outlet position corresponding to the required quantitative water outlet volume; if the quantitative water outlet position of the water volume adjustment knob 10 is already the quantitative water outlet position corresponding to the required quantitative water outlet volume, the water volume adjustment knob 10 can be rotated to other positions first, and then the water volume adjustment knob 10 can be stopped at the quantitative water outlet position corresponding to the required quantitative water outlet volume. After stopping rotating the water volume adjustment knob 10, the water purifier can automatically start to discharge water, and automatically stop discharging water when the water outlet volume reaches the quantitative water outlet volume corresponding to the quantitative water outlet position of the water volume adjustment knob 10, thereby achieving the purpose of quantitative water intake. In addition, the water volume adjustment knob 10 is more reliable than the touch button and is not easy to fail.

[0054] Therefore, the water purification equipment provided in this embodiment can not only achieve the purpose of quantitative water intake, but also improve the water output reliability of the water purification equipment.

[0055] Preferably, the water volume adjustment knob 10 has a quantitative water outlet interval, and each quantitative water outlet position belongs to a continuous position within the quantitative water outlet interval, and the quantitative water outlet positions correspond to gradually increasing quantitative water outlet volumes in a clockwise or counterclockwise direction. Therefore, by rotating the water volume adjustment knob 10 within the quantitative water outlet interval, the maximum quantitative water outlet volume, the minimum quantitative water outlet volume, and any quantitative water outlet volume between the maximum quantitative water outlet volume and the minimum quantitative water outlet volume can be selected. Therefore, the types of quantitative water outlet volumes that can be selected in this embodiment are far more than the types of quantitative water outlet volumes that can be selected by using touch buttons as operating elements, and the applicability is stronger, which is convenient for improving user experience.

[0056] Specifically, the minimum quantitative water output volume that can be selected by the water volume adjustment knob 10 can be set to any value between 0.2 and 2 L, and the maximum quantitative water output volume that can be selected by the water volume adjustment knob 10 can be set to any value between 3 and 5 L.

[0057] In the specific structure of the water purification device provided in this embodiment, a mode adjustment knob 50 can be added (a mode pointer 51 can be set on the mode adjustment knob 50, so as to determine the current water outlet mode by using the indication direction of the mode pointer 51; in addition, an identification can be set on the panel of the water purification device for installing the mode adjustment knob, so as to use the identification as a basis for judging which water outlet mode the current indication direction of the mode pointer 51 represents), and the mode adjustment knob 50 is electrically connected to the controller, and the mode adjustment knob 50 can be rotated and stopped at the open mode position and the closed mode position. When the mode adjustment knob 50 stays in the closed mode position, the controller controls the water circuit control valve to close. At this time, no matter which position the water volume adjustment knob 10 stops, water will not be discharged; when the mode adjustment knob stays in the open mode position, the water volume adjustment knob 10 can function normally, and the controller can control whether the water circuit control valve is opened according to the state of the water volume adjustment knob 10.

[0058] On the basis that the water purification equipment is additionally provided with the above-mentioned mode adjustment knob 50, step a in the control method of the water purification equipment provided in this embodiment may specifically include: if the mode adjustment knob 50 is in the closed mode position, the controller controls the water circuit control valve to close; if the mode adjustment knob 50 is maintained in the open mode position, then when the water volume adjustment knob 10 is rotated and stopped at the quantitative water outlet position, the controller controls the water circuit control valve to open; if the water volume adjustment knob 10 is maintained in the quantitative water outlet position, then when the mode adjustment knob 50 is rotated from the closed mode position to the open mode position, the controller controls the water circuit control valve to open.

[0059] That is to say, when quantitative water extraction is required, if the quantitative water outlet position of the water quantity adjusting knob 10 is already the quantitative water outlet position corresponding to the required quantitative water outlet volume, in addition to the method of rotating the water quantity adjusting knob 10 to other positions first and then stopping the water quantity adjusting knob 10 at the quantitative water outlet position corresponding to the required quantitative water outlet volume to achieve quantitative water extraction, the following method can also be used to achieve quantitative water extraction: keep the position of the water quantity adjusting knob 10 unchanged, stop the mode adjusting knob 50 that was originally in the closed mode position at the open mode position, or rotate the mode adjusting knob 50 that was originally in the open mode position to the closed mode position and then stop it at the open mode position.

[0060] Furthermore, the water volume adjustment knob 10 can be arranged to be able to rotate and stop at a manual water outlet position.

[0061] When it is necessary to take water in an uncontrolled manner, the mode adjustment knob 50 can be rotated to the open mode position (if the mode adjustment knob 50 is originally in the open mode position, there is no need to rotate the mode adjustment knob 50), and the water volume adjustment knob 10 can be rotated to the manual water outlet position (if the water volume adjustment knob 10 is originally in the manual water outlet position, there is no need to rotate the water volume adjustment knob 10). At this time, the controller can control the water circuit control valve to open and start discharging water; when there is no need to continue to take water, the mode adjustment knob 50 can be rotated to the closed mode position. At this time, the controller can control the water circuit control valve to close and stop discharging water. In this way, manual uncontrolled water extraction is realized, the function is more complete, and the user experience is better.

[0062] It should be noted that the water purification equipment provided in this embodiment is suitable for a variety of water purification equipment with different numbers of water outlet modes, such as single-outlet water purification equipment, dual-outlet water purification equipment, triple-outlet water purification equipment, etc. The following takes a dual-outlet water purification equipment with two water outlet modes, purified water and pure water, as an example for detailed description.

[0063] The water channel control valve includes a clean water outlet control valve 20 and a pure water outlet control valve 30 , and the mode adjustment knob 50 can hover in two open mode positions, namely a clean water mode position and a pure water mode position.

[0064] When the mode adjustment knob 50 is rotated to the clean water mode position, the controller can control the opening and closing of the clean water outlet control valve 20 (the opening and closing conditions of the clean water outlet control valve 20 follow the opening and closing conditions of the above-mentioned water circuit control valve); when the mode adjustment knob 50 is rotated to the pure water mode position, the controller can control the opening and closing of the pure water outlet control valve 30 (the opening and closing conditions of the pure water outlet control valve 30 follow the opening and closing conditions of the above-mentioned water circuit control valve), thereby, different water outlet modes can be adjusted by rotating the mode adjustment knob 50.

[0065] In particular, the water channel control valve may be configured as a solenoid valve.

[0066] Specifically, the mode adjustment knob 50 can be set to a ring shape, the water volume adjustment knob 10 can be set to a circle, and the mode adjustment knob 50 can be ringed around the outer periphery of the water volume adjustment knob 10, thereby reducing the occupied area of ​​the mode adjustment knob 50 and the water volume adjustment knob 10 and achieving a better visual effect.

[0067] Preferably, a display can be added to the water purification device provided in the present embodiment, and the display can be electrically connected to the controller so that the display can display the quantitative water output volume corresponding to the quantitative water output position of the water quantity adjustment knob 10. Thus, the user can observe the current quantitative water output volume more intuitively through the display, which is convenient for the user to better judge whether the water quantity adjustment knob 10 is currently in a suitable quantitative water output position, so as to determine whether the water quantity adjustment knob 10 still needs to be rotated. As a result, the user's final water intake will be closer to or even equal to the ideal water intake.

[0068] In addition, the controller can also be provided with a function of obtaining the cumulative water output volume according to the parameters measured by the metering device, and converting the cumulative water output volume into the service life of each filter element 80 of the water purification equipment. On this basis, the display can be used to display the service life of each filter element 80 converted by the controller, so that the user can more intuitively obtain the usage status of the filter element 80 and replace the filter element 80 in time when it is necessary.

[0069] In particular, the above-mentioned display can be provided as an LED display.

[0070] Specifically, the above-mentioned metering device can be either the flow meter 60 or the booster pump 70. If it is the flow meter 60, the controller accumulates the flow measured by the flow meter 60 from zero (or calculates the increment of the water output) each time the water circuit control valve is opened, and uses the accumulated value as the actual water output volume after the water circuit control valve is opened; if it is the booster pump 70, the controller counts the running time of the booster pump 70 from zero (or calculates the time increment) each time the water circuit control valve is opened, converts the counted time into the accumulated water output, and uses the accumulated water output as the actual water output volume after the water circuit control valve is opened.

[0071] In summary, the present invention discloses a water purification device and a control method thereof, which overcomes many technical defects of traditional water purification devices. The water purification device and the control method thereof provided in this embodiment can not only achieve the purpose of quantitative water intake, but also improve the water output reliability of the water purification device.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
