[0023] The following will be describedFigure 1 The water treatment device provided by the embodiment of the present application comprises a water purification pipeline, the water purification pipeline comprises a first filter core 1, a second filter core 2 and a hot water tank 3 which are sequentially connected, a vacuum pump 4 and an exhaust electromagnetic valve 5 are arranged between the first filter core 1 and the second filter core 2, and the exhaust electromagnetic valve 5 is used for controlling the vacuum pump 4 to pump the water purification pipeline to be vacuumized.

[0024] The first filter core 1 of the water treatment device is used for simply filtering water and filtering out macromolecules, the second filter core 2 is used for finely filtering water and filtering out small-molecule harmful substances, and the hot water tank 3 is used for heating the purified normal-temperature water to provide hot water. The vacuum pump 4 and the exhaust electromagnetic valve 5 are arranged in the water purification pipeline, and the air in the water purification pipeline is pumped out to form a negative pressure to achieve a micro-vacuum state after the water treatment device stops being used, so that the oxygen content in the water purification pipeline can be effectively reduced, and the survival of bacteria and other microorganisms is not conducive, so that the effect of inhibiting bacteria in the whole pipeline is achieved, and the water quality safety is improved.

[0025] The vacuum pump 4 is arranged between the first filter core 1 and the second filter core 2, and is mainly used for inhibiting bacteria in the normal-temperature water pipeline. After the water treatment device stops being used, all the water in the water purification pipeline is pumped out, the vacuum pump 4 pumps the water purification pipeline to be vacuumized, so that when the user prepares the first cup of water, there is no water in the pipeline, the first cup of water is newly prepared, and the bacterial content is greatly reduced. Because the internal pipeline forms a negative pressure environment under the action of the vacuum pump, the negative pressure state has a significant acceleration effect on the water flow. When the external water source flows into the pipeline in the negative pressure state, the water flow speed will be accelerated due to the driving of the pressure difference, which is conducive to improving the water preparation efficiency to obtain the required first cup of water faster.

[0026] Further, a diaphragm pump 6 is arranged on the water inlet pipeline between the first filter core 1 and the second filter core 2, which is used for pumping external water to provide pressure for water inlet, so as to ensure that the water flow can stably and efficiently pass through the filter core, and the filtering efficiency is improved.

[0027] Further, a water inlet electromagnetic valve 7 is further arranged on the water inlet pipeline, and the water inlet electromagnetic valve 7 is in communication with the water outlet end of the first filter core 1 and the water inlet end of the diaphragm pump 6. Through accurate control of the water inlet electromagnetic valve 7, the stability and controllability of the water inlet amount of the water purification pipeline can be ensured, and the efficiency and safety of water treatment are improved.

[0028] Further, the wastewater outlet of the second filter core 2 is in communication with a wastewater pipeline of the water purification pipeline, and a wastewater electromagnetic valve 8 is arranged on the wastewater pipeline and is used for controlling the opening and closing of the wastewater pipeline. Through accurate control of the wastewater electromagnetic valve 8, the wastewater can be discharged in time and effectively, and the influence of the wastewater on the water quality is avoided. The water in the water purification pipeline can be pumped out through the wastewater electromagnetic valve 8 after the water treatment device stops.

[0029] Further, the water purification outlet of the secondary filter element 2 is in communication with the normal-temperature water pipeline of the water purification pipeline, and a normal-temperature water electromagnetic valve 9 is arranged on the normal-temperature water pipeline to control the opening and closing of the normal-temperature water pipeline. Through accurate control of the normal-temperature water electromagnetic valve 9, it can be ensured that the normal-temperature water can be stably and safely supplied to the user, and the user experience is improved.

[0030] Further, the water inlet end of the hot water tank 3 is provided with a water supplementing electromagnetic valve 10 to control the water inlet of the hot water tank 3. The water outlet end of the hot water tank 3 is provided with a hot water electromagnetic valve 11 to control the opening and closing of the hot water outlet.

[0031] Further, a pressure gauge is arranged, which is arranged on the water purification pipeline and is in communication with the vacuum pump 4. Specifically, the pressure gauge is arranged on the water purification pipeline and is in communication with the vacuum pump 4 to ensure that the air pressure value in the pipeline can be monitored in real time. The real-time monitoring of the pressure gauge can provide a reliable basis for the operation of the vacuum pump 4, and ensure the stability and controllability of the air pressure in the water purification pipeline.

[0032] Further, a main control board is arranged, which is in communication connection with the exhaust electromagnetic valve 5, the water inlet electromagnetic valve 7, the waste water electromagnetic valve 8, the water supplementing electromagnetic valve 10 and the pressure gauge. The main control board is used to control the opening and closing and operating state of each component according to the control instruction, to realize the automation and intelligentization of water treatment, and to improve the efficiency and safety of water treatment.

[0033] Further, a timing unit is arranged, which is arranged in the main control board or is in communication connection with the main control board, and is used to obtain the time length information of different operating states of the water treatment device. The time length information of different operating states of the water treatment device is obtained by the timing unit, such as the running time and the shutdown time of the water treatment device. According to the time length information of different operating states of the water treatment device, the main control board can make corresponding judgment and control operation. The introduction of the timing unit provides a reliable time basis for the operating state of the water treatment device, which is helpful to realize more accurate control and judgment.

[0034] Further, the main control board is provided with a timing unit, which is used to judge whether the user has used the water treatment device within the first preset time according to the time length information of different operating states; if not, it is judged whether it is within the preset bacteriostatic time; if it is within the preset bacteriostatic time, the waste water electromagnetic valve 8 is controlled to open for pipeline drainage, and then the waste water electromagnetic valve 8 is controlled to close, and the exhaust electromagnetic valve 5 and the vacuum pump 4 are controlled to open; according to the pressure gauge, it is judged whether the pressure in the water purification pipeline reaches the first set value; after reaching, the exhaust electromagnetic valve 5 and the vacuum pump 4 are controlled to close, forming a micro-vacuum state.

[0035] The bacteriostatic control process of the water treatment device in this embodiment is as follows:

[0036] According to the time length information of different operating states of the water treatment device, it is judged whether the user has used the water treatment device within 10 minutes;

[0037] If used, continue monitoring;

[0038] If not used, determine whether it is in the preset antibacterial time (such as early morning, etc. User less time period);

[0039] If it is in the preset antibacterial time, control the waste water electromagnetic valve 8 to open for pipeline drainage;

[0040] After the drainage is completed, the waste water electromagnetic valve 8 is closed, and the exhaust electromagnetic valve 5 and the vacuum pump 4 are opened;

[0041] According to the barometer, determine whether the pressure in the clean water pipeline reaches the first set value;

[0042] After reaching, control the exhaust electromagnetic valve 5 and the vacuum pump 4 to be closed, and form a micro vacuum state.

[0043] The first preset time can be set according to the user's daily water usage habits, for example, the first preset time is 10 minutes. Within 10 minutes, the water treatment device is not used, which usually means that the user is not in the water peak period or may have left the water area. The length of time can effectively capture the pause of the user's water activity, and can also avoid too frequent false judgments.

[0044] The embodiment also increases the barometer on the basis of the vacuum pump 4, and realizes the effect of active water leakage detection by judging the air pressure value in the exhaust process and the recovery of the air pressure value after exhaust.

[0045] The air pressure value judgment step in the clean water pipeline exhaust process of the embodiment:

[0046] Start the process, open the exhaust electromagnetic valve 5 and the vacuum pump 4;

[0047] Monitor the air pressure decay value within the second preset time, and determine whether the value is greater than the second set value;

[0048] If the air pressure decay value is greater than the second set value, the air pressure decay value is repeatedly monitored;

[0049] If the air pressure decay value is less than or equal to the second set value, it is determined that there is a water leakage in the clean water pipeline, the device alarm is triggered, and the process is ended.

[0050] The second preset time in the embodiment can be set to 3 minutes. The decay value of the air pressure is monitored within the second preset time. It is necessary to ensure that there are sufficient data points to evaluate the trend of the change of the air pressure, and it is also necessary to ensure that the subsequent water leakage detection or processing steps are not delayed due to too long time. The second set value can be set according to the air pressure change rate and range during the exhaust process. The second set value is used to determine whether the decay value of the air pressure during the exhaust process is normal. If the air pressure decay value is greater than the second set value, it indicates that there may be a pipeline air leakage or exhaust obstruction condition; if it is less than or equal to the second set value, it may indicate that there is a water leakage in the pipeline.

[0051] The air pressure value judgment step in the locked micro-vacuum state after the exhaust in the embodiment is as follows:

[0052] The starting process is started, and the system enters a locked vacuum state.

[0053] The air pressure decay value is monitored within a third preset time, and it is determined whether the value is greater than a third set value.

[0054] If the air pressure decay value is greater than the third set value, the air pressure decay value is repeatedly monitored.

[0055] If the air pressure decay value is less than or equal to the third set value, it is determined that there is a water leakage in the clean water pipeline, an equipment alarm is triggered, and the process is ended.

[0056] The third preset time in the embodiment can be set to 10 minutes. In the locked micro-vacuum state after the exhaust, a longer time is needed to stabilize the air pressure and monitor the decay value thereof. The time length of 10 minutes can ensure that the air pressure has been sufficiently stabilized, and can also provide sufficient data to accurately evaluate whether there is a water leakage in the pipeline. The third set value needs to be set according to the air pressure stability requirement in the locked micro-vacuum state. The third set value is used to determine whether the decay value of the air pressure in the locked micro-vacuum state is beyond the normal range, so as to ensure that the potential water leakage problem can be detected in time while maintaining the micro-vacuum state.
