When a traditional water purifier is not in use, impurities inside the filter element will diffuse into the pipes, contaminating the pure water. The pure water between the water outlet re-suction valve and the water tank will also be contaminated due to contact with the air; when the water purifier is used again, the TDS (Total Dissolved Solids) value of the water that initially flows out is high, that is, the water quality of the so-called "first cup of water" is problematic. If you want to use cleaner water, you need to leave it empty for a while to drain the "first cup of water", which will cause waste and require waiting. For many users, the experience is not good.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0034] Please also read Figure 1 , Figure 2 , Figure 3 and Figure 4 The embodiment of the utility model provides a water purification device 100, which includes a filter element 20, a waterway plate 10, a buffer water tank 50 and a back-suction assembly 30. The waterway plate 10 includes a reflux pipe 11, a water outlet pipe 12 and a pure water pipe 13, and the filter element 20 is connected to the reflux pipe 11 and the pure water pipe 13 respectively; one end of the buffer water tank 50 is connected to the pure water pipe 13, and the other end is connected to the water outlet pipe 12; one end of the back-suction assembly 30 is connected to the water outlet pipe 12, and the other end is connected to the filter element 20.
[0035] In this embodiment, the water outlet pipe 12 is used to discharge the pure water filtered by the filter element 20, and the water outlet pipe 12 is connected to the filter element 20 through the back-suction assembly 30. When the water purification device 100 is turned off, pure water may remain on the water outlet pipe 12. At this time, the residual pure water in the water outlet pipe 12 can be sucked back into the reflux pipe 11 by controlling the back-suction assembly 30, and the residual pure water can be introduced into the filter element 20 through the reflux pipe 11. Through such a setting, it is possible to prevent the residual pure water in the water outlet pipe 12 from mixing with the pure water after the water purification device 100 is turned on next time, and the problem of low temperature of the first cup of water can be prevented.
[0036] In addition, the reflux pipe 11 is connected to the filter element 20, and the pure water in the pure water pipe 13 can enter the filter element 20 through the reflux pipe 11, thereby flushing and cleaning the filter element 20 and removing the dirt and impurities in the filter element 20. Through such a setting, the filtering effect of the filter element 20 can be improved, thereby preventing the problem of too much dirt and impurities in the filter element 20, which leads to a low TDS value of the first cup of water.
[0037] It should be noted that a wastewater pipe is also provided on the waterway plate 10, and the wastewater pipe is connected to the wastewater port of the filter element 20. The wastewater in the filter element 20 (for example, the wastewater after flushing and cleaning the filter element 20 can be introduced into the wastewater pipe through the wastewater port and discharged to the external environment through the wastewater pipe).
[0038] The pure water pipe 13, the waste water pipe and the return pipe 11 are all arranged on the waterway plate 10. By integrating the pure water pipe 13, the waste water pipe and the return pipe 11 on the waterway plate 10, it is not necessary to separately mold and splice the pipes, thereby reducing the production cost; and the pipe distribution of the waterway plate 10 can be made simpler than the spliced pipe distribution.
[0039] In some specific examples, a buffer water tank 50 is provided between the pure water pipeline 13 and the water outlet pipeline 12 , and the pure water in the pure water pipeline 13 can first pass through the buffer water tank 50 and then be discharged through the water outlet pipeline 12 .
[0040] In some embodiments, the water purification device 100 further includes a booster pump 40, and the return pipe 11 includes a first flow channel 111 and a second flow channel 112, which are interconnected through a first valve 113; the first flow channel 111 is connected to the filter element 20, and is used to introduce the water flow initially filtered by the filter element 20 into the first flow channel 111; the second flow channel 112 is interconnected with the booster pump 40. The return pipe 11 further includes a third flow channel 114, one end of the third flow channel 114 is connected to the booster pump 40, and the other end is connected to the filter element 20, and is used to introduce the water flow into the filter element 20 for secondary filtration to obtain pure water.
[0041] The water flow initially filtered in the filter element 20 can be introduced into the first flow channel 111, and introduced into the second flow channel 112 through the first valve 113, and then enter the booster pump 40 through the second flow channel 112. The booster pump 40 increases the water pressure of the water flow and introduces it into the filter element 20 through the third flow channel 114, so that the water flow has sufficient water pressure to be filtered twice in the filter element 20. Through such a setting, sufficient water pressure can be provided to the water flow to enter the filter element 20, which can ensure that the water flow passes through the filter element 20 smoothly, so that the purification process is more efficient and thorough to obtain pure water.
[0042] The booster pump 40 is a commonly available booster pump 40 on the market, and its model can be selected according to actual conditions.
[0043] It should be noted that whether the water flow in the first flow channel 111 enters the second flow channel 112 can be controlled by opening or closing the first valve 113 .
[0044] In some embodiments, the pure water pipeline 13 includes a fourth flow channel 131, which is connected to the second flow channel 112 through a second valve 132; the pure water in the fourth flow channel 131 can be introduced into the boosting pump 40 through the second flow channel 112, and introduced into the filter element 20 from the third flow channel 114 through the boosting pump 40 to flush the filter element 20.
[0045] The fourth flow channel 131 is provided with a second valve 132. When the second valve 132 is opened, the pure water in the fourth flow channel 131 can enter the second flow channel 112 through the second valve 132. At this time, the pure water in the second flow channel 112 can enter the third flow channel 114 through the booster pump 40, and enter the filter element 20 through the third flow channel 114 to rinse and clean the filter element 20, thereby cleaning the dirt and impurities in the filter element 20. With such a setting, the filtering effect of the filter element 20 can be improved.
[0046] It should be noted that when the second valve 132 is opened, the first valve 113 is closed. At this time, the water in the first flow channel 111 cannot enter the second flow channel 112, and the second flow channel 112 is only connected to the fourth flow channel 131. Through such a setting, the water in the first flow channel 111 can be prevented from mixing with the pure water in the fourth flow channel 131.
[0047] In some embodiments, the pure water pipeline 13 further includes a fifth flow channel 133, which is connected to the buffer water tank 50 and introduced into the water outlet pipeline 12 through the buffer water tank 50. The pure water in the fifth flow channel 133 can enter the buffer water tank 50, and enter the water outlet pipeline 12 through the buffer water tank 50, thereby realizing the discharge of pure water for use by users.
[0048] More specifically, a flow meter may be provided between the fifth flow channel 133 and the buffer water tank 50 to monitor the flow rate of water entering the buffer water tank 50 .
[0049] In some embodiments, the back-suction assembly 30 includes a back-suction valve 31 and a back-suction pipe 32 , and one end of the back-suction pipe 32 is connected to the buffer water tank 50 through the back-suction valve 31 .
[0050] When the water purification device 100 stops working, some pure water may remain in the water outlet pipe 12. At this time, the re-sucking valve 31 is opened, and the pure water remaining in the water outlet pipe 12 can be sucked back into the buffer water tank 50, and then sucked back into the re-sucking pipe 32 through the buffer water tank 50. Through such a setting, the pure water in the water outlet pipe 12 can be sucked back, thereby preventing the temperature of the first cup of water from being too low after the pure water and the residual pure water in the water outlet pipe 12 are mixed after the water purification device 100 is subsequently opened.
[0051] In some embodiments, the other end of the back-suction pipe 32 is connected to the filter element 20. After the back-suction pipe 32 back-suctions the residual pure water in the water outlet pipe 12 through the back-suction valve 31, the back-suction pipe 32 can introduce the portion of pure water into the reflux pipe 11, and then introduce it into the filter element 20 through the reflux pipe 11. With such a setting, the residual pure water in the water outlet pipe 12 can be introduced into the filter element 20, and then discharged from the waste water pipe through the filter element 20.
[0052] In some embodiments, a heating tank 60 is provided between the water outlet pipe 12 and the buffer water tank 50 , and the heating tank 60 is used to heat the water flow introduced into the buffer water tank 50 toward the water outlet pipe 12 .
[0053] Specifically, by setting a heating tank 60 between the water outlet pipe 12 and the buffer water tank 50, pure water can be heated, and then the heated pure water is discharged through the heating tank 60, so that pure water with a higher temperature can be obtained for use, so as to provide users with a better use experience.
[0054] More specifically, when back-sucking is performed, the remaining pure water flows back to the buffer water tank 50 through the hot water tank, enters the back-sucking pipe 32 through the buffer water tank 50, then enters the reflux pipe 11 through the back-sucking pipe 32, and finally enters the filter element 20 through the reflux pipe 11. After the remaining pure water enters the hot water tank, the hot water in the hot water tank is pushed out to the buffer water tank 50, and then the buffer water tank 50 pushes the water stored therein into the back-sucking pipe 32. With such a configuration, the hot water in the heating tank 60 can be prevented from being back-sucked into the filter element 20.
[0055] In some embodiments, the buffer water tank 50 is provided with a water inlet valve 51, which is used to control the water flow from the buffer water tank 50 into the heating tank 60. The heating tank 60 includes a three-way pipe 61, and the water inlet valve 51 includes a first flow port 511 and a second flow port 512; the first flow port 511 is connected to the water outlet pipe 12 through the three-way pipe 61; the second flow port 512 is connected to the heating tank 60, and the heating tank 60 is connected to the three-way pipe 61.
[0056] In this embodiment, the first flow port 511 and the second flow port 512 of the water inlet valve 51 are connected to the heating tank 60 and the three-way pipe 61, respectively. When the first flow port 511 is closed and the second flow port 512 is opened, the hot water in the heating tank 60 is pushed out and enters the water outlet pipe 12 through the three-way pipe 61, thereby obtaining pure water at a relatively high temperature; when the second flow port 512 is closed and the first flow port 511 is opened, the water flow in the buffer water tank 50 directly enters the water outlet pipe 12 through the three-way pipe 61, thereby obtaining pure water at normal temperature; when the first flow port 511 and the second flow port 512 are both opened, the normal temperature water and the hot water in the heating tank 60 are mixed in the three-way pipe 61 and then introduced into the water outlet pipe 12, thereby obtaining pure water at a moderate temperature.
