The water purification system of the water purification system usually includes a pre-filter element, a precision filter element, and a post-treatment filter element. The pre-filter element is used to remove organic matter, colloids, heavy metals and sediment particles, etc. The precision filter element is extremely accurate, such as the reverse osmosis membrane filter element (RO filter element), which is the core treatment filter element of the water purification system. The post-treatment filter element is used to remove trace elements, adjust pH and drinking taste, etc.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0074] Combine the following Figures 1 to 7 , describing an embodiment of the present invention.

[0075] like Figure 1 , Figure 2 or Figure 3 As shown, according to an embodiment of the present invention, on the one hand, a water purification system is disclosed, including a pre-filter element 1 and a microwave generator 2, wherein the pre-filter element 1 contains an activated carbon component, the pre-filter element 1 has a pre-filter element water outlet 12, the microwave generator 2 is connected to the pre-filter element 1, the microwave generator 2 has a first working frequency and a second working frequency, the first working frequency is less than the second working frequency, based on the water purification system being in a regeneration state, the water inside the pre-filter element 1 is discharged through the pre-filter element water outlet 12, the microwave generator 2 first works at the first working frequency for a first preset time, and then works at the second working frequency for a second preset time to perform microwave regeneration on the pre-filter element 1.

[0076] The water purification system of the present application is provided with a microwave generator 2 having a first working frequency and a second working frequency, wherein the first working frequency is less than the second working frequency. When the water purification system is in a regeneration state, the water inside the pre-filter element 1 is first drained, and the microwave generator 2 is started to work at the first working frequency for a first preset time to perform low-frequency microwave regeneration on the pre-filter element 1, which can make the adsorbent on the surface of the activated carbon of the pre-filter element 1 parse and desorb, and then the microwave generator 2 is controlled to work at the second working frequency for a second preset time to further perform high-frequency microwave regeneration on the pre-filter element 1, which can make the adsorbent inside the activated carbon of the pre-filter element 1 parse and desorb. The microwave regeneration technology has the advantages of not introducing secondary pollution, fast heating speed, high regeneration efficiency and low exhaust gas generation. The present application performs low-frequency and high-frequency microwave regeneration on the pre-filter element 1 through the microwave generator 2, thereby realizing the active regeneration of the surface and inside of the activated carbon of the pre-filter element 1, effectively improving the life of the pre-filter element 1 and extending the core replacement cycle, removing restrictions on the increase of the nominal value of the rated water purification volume of the whole machine and improving product competitiveness.

[0077] The microwave regeneration principle is that the microwave energy generated by the microwave generator 2 induces the substance molecules adsorbed by the activated carbon of the pre-filter 1 to produce dipole steering polarization in the microwave field, and quickly converts the microwave energy into heat energy, thereby restoring the adsorption performance of the activated carbon and improving the service life of the pre-filter 1.

[0078] Optionally, the pre-filter 1 can be set as a carbon composite filter composed of a first-level PP cotton, ultrafiltration and activated carbon in series, which can filter colloids, heavy metals and sediment particles, etc., and can remove oxidizing substances such as residual chlorine.

[0079] The microwave generating device 2 is used to emit microwaves to the interior of the pre-filter element 1 . The microwave energy is converted into heat energy to heat and regenerate the pre-filter element 1 .

[0080] In terms of specific structure, Figure 5As shown, in some embodiments, the microwave generating device 2 includes a shell 21 and a microwave generator 22, wherein the shell 21 is connected to the pre-filter element 1, the microwave generator 22 has a microwave emitting end 221, the microwave generator 22 is arranged inside the shell 21, and the microwave emitting end 221 passes through the shell 21 and extends into the interior of the pre-filter element 1.

[0081] The housing 21 protects the internal microwave generator 22 . When the microwave generator 22 is powered on, the microwave emitting end 221 emits microwaves to the interior of the pre-filter element 1 , and the microwaves regenerate the pre-filter element 1 .

[0082] like Figure 1 or Figure 4 As shown, in some embodiments, the microwave generating device 2 is disposed at the bottom of the pre-filter element 1 .

[0083] By arranging the microwave generating device 2 at the bottom of the pre-filter element 1, the interference between the microwave generating device 2 and components such as pipelines and valves on the pre-filter element 1 can be reduced, thereby ensuring the independent use of each.

[0084] Specifically, an end cover is provided at the bottom of the pre-filter element 1 , the microwave generating device 2 is embedded in the end cover, and the microwave emitting end 221 of the microwave generating device 2 extends into the interior of the pre-filter element 1 through the end cover to transmit microwaves to the interior of the pre-filter element 1 .

[0085] like Figure 2 As shown, in some embodiments, the microwave generating device 2 is disposed on the top of the pre-filter element 1 .

[0086] In this solution, the microwave generating device 2 is arranged on the top of the pre-filter element 1, so that the microwave generating device 2 and other components are integrated to improve the compactness of each structure.

[0087] like Figure 3 As shown, in some embodiments, two microwave generating devices 2 are provided and the two microwave generating devices 2 are arranged oppositely at the sides of the pre-filter element 1 .

[0088] In this scheme, when the two microwave generating devices 2 are placed on the side of the pre-filter element 1 , the two microwave generating devices 2 are more conducive to creating a uniform microwave energy field inside the pre-filter element 1 , thereby enhancing the microwave regeneration effect on the pre-filter element 1 .

[0089] like Figure 1 , Figure 2 or Figure 3As shown, in some embodiments, the water purification system also includes a fine filter element 3 and a wastewater discharge pipeline 400, wherein the fine filter element 3 has a fine filter element water inlet 31, a wastewater outlet 33 and a pure water outlet 32, the fine filter element water inlet 31 and the pre-filter element water outlet 12 are connected by a first pipeline, the first pipeline is provided with a pressure-stabilizing pump 301, the wastewater discharge pipeline 400 is connected to the wastewater outlet 33, and the wastewater discharge pipeline 400 is provided with a wastewater valve 401.

[0090] When the water purification system is in the regeneration state, the water in the pre-filter element 1 is discharged to the first pipeline through the pre-filter element water outlet 12, and then discharged into the fine filter element 3 through the first pipeline and discharged through the wastewater discharge pipeline 400 and the pure water outlet 32, thereby emptying the water in the pre-filter element 1.

[0091] Of course, when the water purification system is purifying water normally, the fine filter element 3 is used to perform high-precision filtration on tap water. The tap water flows into the fine filter element 3 through the fine filter element water inlet 31. The pure water produced after filtration is discharged through the pure water outlet 32, and the waste water produced is discharged to the wastewater discharge pipeline 400 through the wastewater outlet 33.

[0092] The fine filter element 3 has higher filtering accuracy than the pre-filter element 1 and can further purify the tap water with high precision. It is the core treatment filter element of the water purification system.

[0093] The fine filter element 3 can specifically be a reverse osmosis membrane filter element (RO filter element), a ceramic filter element, etc., which is selected according to the filtering requirements and is not specifically limited in this embodiment.

[0094] In some embodiments, the water purification system also includes a post-filter element 4, which has a post-filter element water inlet 41 and a post-filter element water outlet 42. The post-filter element water inlet 41 and the pure water port 32 are connected by a second pipeline 500, and the post-filter element water outlet 42 is connected to the pure water pipeline 600.

[0095] When the water purification system is purifying water normally, the post-filter element 4 can filter the pure water flowing out of the fine filter element 3 again to improve the taste of pure water. When the water purification system is in a regeneration state and needs to be drained, the water in the pre-filter element 1 is discharged into the fine filter element 3 through the first pipeline and then discharged through the pure water port 32, the second pipeline 500, the post-filter element 4, the pure water pipeline 600, and the waste water discharge pipeline 400.

[0096] Specifically, the post-filter element 4 may be a post-activated carbon filter element containing activated carbon components.

[0097] The second pipeline 500 is provided with a check valve 501 , which can prevent the pure water in the post-filter element 4 from flowing back into the fine filter element 3 .

[0098] like Figures 1 to 4As shown in any one of the figures, in order to improve the compactness of the structure and reduce the volume of the whole machine, in some embodiments, the pre-filter element 1 and the post-filter element 4 can be integrated to form a composite filter element. For example, the pre-filter element 1 and the post-filter element 4 can be independently separated and arranged in the inner cavity of the same filter bottle, and the pre-filter element water inlet 11, the pre-filter element water outlet 12, the post-filter element water inlet 41 and the post-filter element water outlet 42 are all arranged at the top of the filter bottle, and the microwave generating device 2 can be arranged at the bottom of the filter bottle.

[0099] Preferably, the filter bottle of the composite filter element and the filter bottle of the pre-filter element 1 are made of stainless steel, which is resistant to high temperatures and can withstand the high temperature generated when the microwave generator 2 is working. Specifically, the stainless steel material can be 304 stainless steel or 316 stainless steel, etc., and this embodiment does not make specific restrictions.

[0100] In some embodiments, the pre-filter element 1 also has a pre-filter element water inlet 11, and the water purification system also includes a pre-treatment filter element 5, the pre-treatment filter element 5 has a pre-treatment filter element water inlet and a pre-treatment filter element water outlet, the pre-treatment filter element water inlet is connected to the raw water pipeline 100, the pre-treatment filter element water outlet and the pre-filter element water inlet 11 are connected through the water inlet pipeline 200, and the water inlet pipeline 200 is provided with an inlet valve 201.

[0101] When the water purification system is purifying water normally, the pre-treatment filter element 5 can pre-filter the raw water flowing into the raw water pipeline 100 to filter out large particles of impurities such as mud, rust, etc. in the raw water to ensure the service life of the rear filter element. When the water purification system is in a regeneration state, the water inlet valve 201 is closed to facilitate the drainage of water from the pre-filter element 1.

[0102] In this embodiment, the raw water pipeline 100 is connected to the tap water inlet so as to facilitate the long-distance transportation of the tap water to the water purification system.

[0103] The raw water pipeline 100 is provided with a raw water inlet switch 101, which is used to control the on-off of the raw water pipeline 100. When the raw water inlet switch 101 is turned on, the raw water pipeline 100 is turned on, and tap water can flow into the pre-treatment filter element 5 through the raw water pipeline 100. When the raw water inlet switch 101 is turned off, the raw water pipeline 100 is disconnected, and tap water cannot flow through the raw water pipeline 100 into the pre-treatment filter element 5.

[0104] In order to facilitate the understanding of the water purification system of the present application, the working process of the water purification system is now introduced as follows in conjunction with the accompanying drawings of the specification:

[0105] The water purification system is in the water purification working state: the raw water inlet opening, the water inlet valve 201, the pressure regulating pump 301 and the waste water valve 401 are opened, the microwave generator 2 is in the closed state, the raw water (tap water) flows into the pre-treatment filter element 5 through the raw water inlet opening and the raw water pipeline 100, the pre-treatment filter element 5 pre-filters the raw water to filter out large particles of impurities such as sand and rust in the raw water, the filtered raw water flows through the water inlet pipeline 200 and flows into the pre-filter element 1, the pre-filter element 1 filters the colloids, heavy metals and and sand particles, and removes oxidizing substances such as residual chlorine. The filtered raw water flows into the fine filter element 3 through the first pipeline and the fine filter element water inlet 31. The fine filter element 3 performs high-precision filtration on the raw water. The waste water generated by the filtration is discharged to the waste water discharge pipeline 400 through the waste water outlet 33. The pure water generated after filtration flows into the post-filter element 4 through the pure water outlet 32 ​​and the second pipeline 500. The pure water outlet 32 ​​is used to adjust the sense and pH value of the pure water, and then the pure water flows out through the pure water pipeline 600 for user use.

[0106] The water purification system is in the regeneration state. The operation steps for regeneration are as follows:

[0107] (1) Close the raw water inlet opening, the water inlet valve 201 and the microwave generator 2, open the pressure regulating pump 301 and the waste water valve 401, and the water in the pre-filter element 1 flows into the first pipeline through the pre-filter element outlet 12, and is discharged through the fine filter element 3, the waste water discharge pipeline 400, the second pipeline 500, the post-filter element 4, and the pure water pipeline 600. The drainage time lasts for 1 minute to 10 minutes;

[0109] (3) The microwave generator 2 is turned off, and the pressure regulating pump 301 and the waste water valve 401 are turned on. The water vapor in the pre-filter element 1 flows into the first pipeline through the pre-filter element water outlet 12, and is discharged through the fine filter element 3, the waste water discharge pipeline 400, the second pipeline 500, the post-filter element 4, and the pure water pipeline 600. The discharge time lasts for 1 minute to 10 minutes.

[0110] (4) Turn off the pressure-stabilizing pump 301 and the wastewater valve 401, and then turn on the microwave generator 2, so that the microwave generator 2 operates at a second operating frequency for a second preset time, wherein the second operating frequency is 2 MHz to 2.5 MHz, and the second preset time is 60 minutes to 120 minutes;

[0111] (5) The microwave generator 2 is turned off, and the pressure regulating pump 301 and the waste water valve 401 are turned on. The water vapor in the pre-filter element 1 flows into the first pipeline through the pre-filter element water outlet 12, and is discharged through the fine filter element 3, the waste water discharge pipeline 400, the second pipeline 500, the post-filter element 4, and the pure water pipeline 600.

[0113] It should be noted that the regeneration triggering condition of the water purification system can be controlled by setting the total amount of purified water. For example, when the total amount of purified water in the water purification system reaches 1000L or 1500L, the water purification system is triggered to enter the regeneration state, and the pre-filter element 1 is actively regenerated, but it is not limited to this. In other embodiments, the regeneration triggering condition of the water purification system can also be controlled by setting the water purification time.

The regeneration method of the water purification system includes:

[0115] Control the pre-filter element 1 to drain the water inside;

[0116] Controlling the microwave generating device 2 to operate at a first operating frequency for a first preset time;

[0117] The microwave generating device 2 is controlled to operate at a second operating frequency for a second preset time, and the second operating frequency is greater than the first operating frequency.

[0118] Since the regeneration method of the water purification system of the present invention is used to regenerate the water purification system of the present invention, the regeneration method of the water purification system of the present invention has the same technical effect as the water purification system, and this embodiment will not be repeated here.

[0119] In some embodiments, before controlling the microwave generating device 2 to operate at the second operating frequency for the second preset time, the method further includes:

[0120] The pre-filter element 1 is controlled to exhaust the water vapor inside.

[0121] After the microwave generating device 2 operates at the first operating frequency for the first preset time, a large amount of water vapor will be generated inside the pre-filter element 1 due to the high temperature. The water vapor inside the pre-filter element 1 is first discharged, and then the microwave generating device 2 is started to operate at the second operating frequency to reduce the impact of moisture on the microwave generating device 2 and ensure the working environment of the microwave generating device 2.

[0122] In some embodiments, after controlling the microwave generating device 2 to operate at the second operating frequency for a second preset time, the method further includes:

[0123] The pre-filter element 1 is controlled to exhaust the water vapor inside.

[0124] After the microwave generating device 2 operates at the second operating frequency for the second preset time, a large amount of water vapor will be generated inside the pre-filter element 1 due to the high temperature. The water vapor will be discharged before the pre-filter element 1 is normally used to achieve rapid cooling of the pre-filter element 1.

[0125] In some embodiments, after the step of controlling the pre-filter element 1 to evacuate the internal water vapor, the method further includes:

[0126] The water purification system is controlled to flush the pre-filter element 1 for a third preset time.

[0131] In some embodiments, in the step of controlling the microwave generating device 2 to operate at a first operating frequency for a first preset time, the first operating frequency is 1 MHz to 1.5 MHz.

[0132] By setting the first operating frequency of the microwave generating device 2 within a reasonable range, it is possible to save energy consumption while ensuring the low-frequency microwave regeneration effect on the pre-filter element 1.

[0134] In some embodiments, in the step of controlling the microwave generating device 2 to operate at the first operating frequency for a first preset time, the first preset time is 30 minutes to 60 minutes.

[0135] By setting the first preset working time of the microwave generating device 2 within a reasonable range, the low-frequency microwave regeneration effect on the pre-filter element 1 can be ensured while reducing the time occupation.

[0136] Exemplarily, the first preset time may be 30 minutes, 35 minutes, 40 minutes, 45 minutes, 50 minutes, 55 minutes, 60 minutes, etc., and may be set according to specific needs, and this embodiment does not impose any specific limitation.

[0137] In some embodiments, in the step of controlling the microwave generating device 2 to operate at a second operating frequency for a second preset time, the second operating frequency is 2 MHz to 2.5 MHz.

[0138] By setting the second operating frequency of the microwave generating device 2 within a reasonable range, it is possible to save energy consumption while ensuring the high-frequency microwave regeneration effect on the pre-filter element 1.

[0139] Exemplarily, the second operating frequency may be 2 MHz, 2.1 MHz, 2.2 MHz, 2.3 MHz, 2.4 MHz, 2.5 MHz, etc., and may be set according to specific needs, and this embodiment does not impose any specific limitation.

[0140] In some embodiments, in the step of controlling the microwave generating device 2 to operate at the second operating frequency for a second preset time, the second preset time is 60 minutes to 120 minutes.

[0141] By setting the second preset working time of the microwave generating device 2 within a reasonable range, the high-frequency microwave regeneration effect on the pre-filter element 1 can be ensured while reducing the time occupation.

[0142] Exemplarily, the second preset time may be 60 minutes, 70 minutes, 80 minutes, 90 minutes, 100 minutes, 110 minutes, 120 minutes, etc., and may be set according to specific needs, and this embodiment does not impose any specific limitation.

[0145] The control module is used to control the microwave generating device 2 to work at a first working frequency for a first preset time, and to control the microwave generating device 2 to work at a second working frequency for a second preset time.
