[0045] In one embodiment, the present application provides an ion purification device for a water purifier, such as Figure 1-Figure 3As shown, the water purifier includes a main body, in which a filter element 200 and a water pipe 500 are arranged. The water pipe 500 has a first through hole 510, a second through hole 520 and a third through hole (not shown in the figure). The filter element 200 is connected to the water pipe 500 through the first through hole 510, and the third through hole is a water outlet. The ion purification device is arranged in the main body, including an ion injection tube 600, a fan 100, a bracket 300 and a bipolar ion generator 400, wherein the ion injection tube 600 is connected to the water pipe 500 through the second through hole 520. The structure of the fan 100, the bracket 300, the bipolar ion generator 400, the filter element 200 and the water pipe 500 is shown in FIG. Figures 1 to 3 As shown, Figure 1 The overall structure diagram of the water purifier is as follows: Figure 2 This is a schematic diagram of the structure of the water purifier after the filter element 200 is hidden. Figure 3 The diagram of the explosion structure of the water purifier is shown in FIG. Figures 1 to 3 In the illustrated embodiment, only the structure of the filter element 200 and part of the structure of the water pipe 500 are schematically shown, while the connection portion between the filter element 200 and the water pipe 500, the third through hole of the water pipe 500 and other components in the water purifier are hidden.

[0046] like Figures 1 to 3 As shown, the interior of the bracket 300 is hollow, one end of the bracket 300 is connected to the air outlet of the fan 100, and the other end is connected to the ion injection tube 600. The bipolar ion generator 400 includes an ion plate 410, a plug 440 and a power converter 450. The ion plate 410 is installed in the bracket 300 and is used to generate an ion group with opposite charges; one end of the plug 440 is pluggably electrically connected to the ion plate 410, and the other end is electrically connected to the power converter 450. The power converter 450 is used to convert electricity for the ion plate 410. The first through hole 510 of the water pipe 500 is located above the second through hole 520. The water filtered by the filter element 200 reaches the water pipe 500 through the first through hole 510. The direction of water flow in the water pipe 500 is as shown in FIG. Figure 3 As shown by the dotted arrow in the water pipe 500, the purified ion airflow in the ion injection pipe 600 is directly introduced into the water flow in the water pipe 500 through the second through hole 520. The flow direction of the purified ion airflow is as follows: Figure 3 As shown by the dotted arrow in the ion injection tube 600. Figure 3 As shown, the end of the ion injection tube 600 connected to the water pipe 500 is in an inverted U shape, thereby preventing the water in the water pipe 500 from flowing back into the ion injection tube 600.

[0047] The airflow generated by the fan 100 enters the bracket 300, carrying the purified ions produced by the ion sheet 410 into the ion injection tube 600. The ions are then injected into the water flow in the water pipe 500 through the second through-hole 520, and then reach the drinking water outlet pipe of the water purifier. The fan 100, bracket 300, bipolar ion generator 400, and ion injection tube 600 occupy a small space and are flexible and convenient to install. The addition of the bipolar ion generator 400 further purifies the drinking water at the water purifier outlet, further ensuring water quality. The negative ions generated by the bipolar ion generator 400 are carried in the drinking water at the outlet, forming negatively ionized water that is closer to the water in human cells and beneficial to health. The negative charge prevents acidification of the water, extending the shelf life of the drinking water at the outlet. Furthermore, the negative ion airflow injected into the drinking water outlet pipe breaks water molecules into many smaller clusters, making them more easily absorbed and utilized by the human body.

[0048] In addition, it should be noted that the present invention does not limit the structure of the water pipe 500 and the ion injection pipe 600, and the connection method of the water pipe 500, the filter element 200, and the ion injection pipe 600. Figure 1-Figure 3 In the embodiment shown, the first through hole 510 is located above the second through hole 520, and the end of the ion injection tube 600 connected to the water pipe 500 is in an inverted U shape. It is understood that in other embodiments, the structure of the water pipe 500 and the ion injection tube 600 can also be other structures, and the connection method of the water pipe 500 to the filter element 200 and the ion injection tube 600 can also be other methods. In another embodiment, as Figure 4 As shown, the first through hole 510 of the water pipe 500 can also be located below the second through hole 520. An insertion tube is provided in the ion injection tube 600. One end of the insertion tube is connected to the ion injection tube 600, and the other end is located below the first through hole 510. Therefore, the water filtered by the filter element 200 reaches the water pipe 500 through the first through hole 510. The direction of water flow in the water pipe 500 is as shown in FIG. Figure 4 As shown by the dotted arrow in the reclaimed water pipe 500, the purified ion airflow in the ion injection tube 600 is sequentially introduced into the water flow in the water pipe 500 through the second through hole 520 and the insertion tube. The setting of the insertion tube, on the one hand, enables the purified ion airflow in the ion injection tube 600 to be introduced into the water flow in the water pipe 500, thereby increasing the solubility of negative ions in the drinking water at the outlet of the water purifier; on the other hand, it can also prevent the water in the water pipe 500 from flowing back into the ion injection tube 600.

[0049] In one embodiment, the structure of the ion plate 410 is as follows: Figure 5 As shown, the structure after the plug 440 is connected to the ion plate 410 is as follows Figure 6 As shown, the structure after the plug 440 is unplugged from the ion plate 410 is as follows Figure 7 As shown. Figure 6 and Figure 7As shown, the plug 440 includes a first plug 441 and a second plug 442, and the first plug 441 and the second plug 442 are pluggably connected to the opposite ends of the ion sheet 410. Figure 8 and Figure 9 As shown, the ion sheet 410 further includes a first electrical connection 431 and a second electrical connection 432. Figure 5 As can be seen in the figure, the ion sheet 410 is a layered rectangle. From one side to the other, the ion sheet 410 includes, in order, a first grounding plate 411, a first dielectric barrier plate 412, a first emitter plate 413, a second dielectric barrier plate 414, a second emitter plate 415, a third dielectric barrier plate 416, and a second grounding plate 417. The first emitter plate 413 and the second emitter plate 415 form a first lead-out terminal 418 at one end of the ion sheet 410. One end of the first electrical connector 431 is electrically connected to the first lead-out terminal 418, and the other end is pluggably electrically connected to the first plug 441. The other end of the first plug 441 is connected to the AC high voltage power supply via the power converter 450. The first grounding electrode 411 and the second grounding electrode 417 form a second lead-out end 419 at the other end of the ion plate 410. One end of the second electrical connector 432 is electrically connected to the second lead-out end 419, and the other end is pluggably electrically connected to the second plug 442. The other end of the second plug 442 is grounded through the power converter 450.

[0050] In a specific embodiment, one end of the first electrical connector 431 is welded to the first lead-out terminal 418 by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used to be pluggably electrically connected to the first plug 441; one end of the second electrical connector 432 is welded to the second lead-out terminal 419 by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used to be pluggably electrically connected to the second plug 442. Figure 8 and Figure 9 As shown, the first electrical connector 431 is provided with a first port 433 for pluggable connection with a first plug 441, and the second electrical connector 432 is provided with a second port 436 for pluggable connection with a second plug 442. Furthermore, to prevent incorrect insertion, the first port 433 is cylindrical and the second port 436 is flat, so that the first plug 441 can only be inserted into the first port 433, and the second plug 442 can only be inserted into the second port 436. Furthermore, a second elastic member 437 is provided on the sidewall of the second port 436. One end of the second elastic member 437 is connected to the sidewall of the second port 436, and the other end is inclined or curved toward the interior of the second port 436. When the second plug 442 is inserted into the second port 436, the second elastic member 437 can press against the second plug 442, so that the second plug 442 can tightly contact the second electrical connector 432, achieving a stable electrical connection.

[0051] Additionally, in one embodiment, Figure 8 As shown, in order to further increase the tight abutment between the first plug 441 and the first electrical connector 431, a third spring clip 435 is further provided on the side wall of the first port 433. One end of the third spring clip 435 is connected to the side wall of the first port 433, and the other end is inclined or bent toward the interior of the first port 433. The first spring clip 434 is provided on the third spring clip 435. When the first plug 441 is inserted into the first port 433, the first spring clip 434 and the third spring clip 435 work together to press the first plug 441, so that the first plug 441 can more tightly contact the first electrical connector 431 to achieve a more stable electrical connection. Similarly, in order to further increase the tight abutment between the second plug 442 and the second port 436, as shown Figure 9 As shown, a fourth spring clip 438 is further provided on the side wall of the second port 436, one end of the fourth spring clip 438 is connected to the side wall of the second port 436, and the other end is inclined or bent toward the interior of the second port 436, and the second spring clip 437 is provided on the fourth spring clip 438. When the second plug 442 is inserted into the second port 436, the second spring clip 437 and the fourth spring clip 438 work together and can both press the second plug 442, so that the second plug 442 can be more tightly in contact with the second electrical connector 432 to achieve a more stable electrical connection.

[0052] from Figure 3 、 Figure 4 、 Figure 6 and Figure 7 As can be seen, the bipolar ion generator 400 also includes a shell 420 made of insulating material. The shell 420 is arranged on the outside of the ion plate 410 and is used to fix the ion plate 410. Hollow areas 423 are opened on both sides of the ion plate 410 on the shell 420 to facilitate the outflow of positively and negatively charged ion groups with opposite signs.

[0053] like Figure 5 As shown, the first emitter plate 413 and the first grounding plate 411 form a first electric field, and the second emitter plate 415 and the second grounding plate 417 form a second electric field. The directions of the first electric field and the second electric field are opposite. The double-sided ion plate 410 with such a symmetrical structure increases the number of escaping electrons per unit time, enhances the ion airflow, and accelerates the speed of air purification. It is understandable that in other embodiments, the ion plate 410 can also include only the first emitter plate 413, the first grounding plate 411 and the first dielectric barrier plate 412, and the first dielectric barrier plate 412 is located between the first emitter plate 413 and the first grounding plate 411. The first electric field is formed between the first emitter plate 413 and the first grounding plate 411, and electrons are drawn from one end of the first emitter plate 413 through the middle first dielectric barrier plate 412 to the first grounding plate 411.

[0054] like Figure 3 and Figure 4 As shown, the bracket 300 includes an upper cover 310 and a lower cover 320, which are used to clamp and fix the ion sheet 410 in the bracket 300; the bracket 300 includes two clamping ends 330, which are used to clamp and fix the opposite ends of the ion sheet 410. Both clamping ends 330 are provided with openings 331, and the inner walls of the two clamping ends 330 are sealed to the external shells 420 at both ends of the ion sheet 410 to prevent the purified ions generated by the ion sheet 410 from flowing out of the openings 331 of the clamping ends 330; a plug 440 is connected to the power converter 450 through the opening 331 of one clamping end 330, and the other plug 440 is connected to the power converter 450 through the opening 331 of the other clamping end 330.

[0055] In another embodiment, the structure of the ion sheet 410 is as follows: Figure 10 As shown, the structure after the plug 440 is connected to the ion plate 410 is as follows Figure 11 As shown, the structure after the plug 440 is unplugged from the ion plate 410 is as follows Figure 12 As shown, the first lead-out terminal 418 and the second lead-out terminal 419 are formed at the same end of the ion sheet 410, one end of the first electrical connector 431 is electrically connected to the first lead-out terminal 418, and the other end is pluggably electrically connected to the first plug 441, and one end of the second electrical connector 432 is electrically connected to the second lead-out terminal 419, and the other end is pluggably electrically connected to the second plug 442, so that the first plug 441 and the second plug 442 are pluggably connected to the same end of the ion sheet 410. It can be understood that when the structure of the bipolar ion generator 400 is as shown in FIG. Figure 10-12 As shown, an opening 331 can be opened only at one clamping end 330 of the bracket 300, and the inner wall of the clamping end 330 with the opening 331 is sealedly connected to the outer wall of the end of the ion sheet 410; both plugs 440 are connected to the power converter 450 through the opening 331 of the clamping end 330.

[0056] In another embodiment, the structure of the ion sheet 410 is as follows: Figure 13-15 As shown, Figure 13 is a schematic structural diagram of the ion sheet 410, Figure 14 Schematic diagram of the exploded structure of the ion sheet 410, the housing 420, the first plug 441 and the second plug 442. Figure 15FIG4 is a transverse cross-sectional view of the ion sheet 410. From one side to the other, the ion sheet 410 includes, in sequence, a first grounding plate 411, a first dielectric barrier plate 412, a first emitter plate 413, a second dielectric barrier plate 414, a second emitter plate 415, a third dielectric barrier plate 416, and a second grounding plate 417. The first dielectric barrier plate 412 and the third dielectric barrier plate 416 are smaller in width than the second dielectric barrier plate 414, thereby forming steps 460 between the first dielectric barrier plate 412 and the second dielectric barrier plate 414 and between the third dielectric barrier plate 416 and the second dielectric barrier plate 414. The housing 420 includes an upper housing 421 and a lower housing 422. Hollow regions 423 are provided on the upper and lower housings 421 and 422 on the upper and lower sides of the ion sheet 410 to facilitate the outflow of positively and negatively charged ion groups. The upper shell 421 and the lower shell 422 are clamped on the steps 460 on the upper and lower sides of the third dielectric blocking plate 416, so that the surface of the shell 420 is flush with the surface of the ion sheet 410, or the surface of the shell 420 is recessed in the surface of the ion sheet 410, thereby making it easier for positively and negatively charged ion groups with opposite signs to flow out from the hollow area 423.

[0057] In another embodiment, the structure of the ion plate 410 is as follows: Figures 16 to 20 As shown, Figure 16 is a schematic structural diagram of the ion sheet 410, Figure 17 Schematic diagram of the explosion structure of the ion sheet 410 and the shell 420. Figure 18 Schematic diagram of the structure after the plug 440 is connected to the ion sheet 410, Figure 19 This is a schematic diagram of the structure after the plug 440 is unplugged from the ion plate 410. Figure 20 The figure is a transverse cross-sectional view of the ion plate 410. The ion plate 410 includes, from one side to the other, a first grounding plate 411, a first dielectric barrier plate 412, a first emitter plate 413, a second dielectric barrier plate 414, and a second grounding plate 417. The first emitter plate 413 forms a first lead-out terminal 418 at one end of the ion plate 410. One end of a first electrical connector 431 is electrically connected to the first lead-out terminal 418, and the other end is pluggably electrically connected to a first plug 441. The other end of the first plug 441 is connected to an AC high voltage power source via a power converter 450. The first grounding plate 411 and the second grounding plate 417 form a second lead-out terminal 419 at the same end of the ion plate 410. One end of a second electrical connector 432 is electrically connected to the second lead-out terminal 419, and the other end is pluggably electrically connected to a second plug 442. The other end of the second plug 442 is grounded via a power converter 450.

[0058] like Figure 16As shown, one side of the first emitter plate 413 forms a first electric field with the first grounding plate 411, and the other side forms a second electric field with the second grounding plate 417. Thus, the double-sided ion plate 410 with a symmetrical structure increases the number of electrons emitted per unit time, strengthens the ion flow, and speeds up the air purification. In addition, as Figure 17-Figure 10 As shown, the opposite ends of the housing 420 are respectively clamped to the opposite ends of the ion sheet 410, and there is a gap 470 between the two sides of the ion sheet 410 and the two sides of the housing 420. This design can free the sides of the ion sheet 410 from the constraints of the housing 420, making it easier for positive and negative charged ions to flow out from the hollow area 423, thereby increasing the efficiency of the ion group outflow.

[0059] In addition, if Figures 17 to 19 As shown, the first electrical connector 431 and the second electrical connector 432 are both arranged inside the shell 420. The end of the shell 420 is provided with a first connection hole 424 and a second connection hole 425. The first plug 441 is pluggable and electrically connected to the ion sheet 410 through the first connection hole 424; the second plug 442 is pluggable and electrically connected to the ion sheet 410 through the second connection hole 425. Figure 6 、 Figure 7 as well as Figure 11 、 Figure 12 Compared to the embodiment shown in Figure 18 and Figure 19 In the embodiment shown, the outer walls of the first connection hole 424 and the second connection hole 425 do not protrude from the end of the shell 420, thereby reducing the length of the shell 420 and further reducing the length of the ion plate 410, making it easier to install the ion plate 410 in a small space.

[0060] In addition, if Figure 6 、 Figure 7 、 Figure 11 、 Figure 12 As shown, the cross section of the first connection hole 424 is circular, and accordingly the insertion end of the first plug 441 is also circular. The cross section of the second connection hole 425 is elliptical, and accordingly the insertion end of the second plug 442 is also elliptical, so that the first plug 441 can only be inserted into the first connection hole 424, and the second plug 442 can only be inserted into the second connection hole 425, to avoid wrong insertion. Figure 18 and Figure 19 In the illustrated embodiment, the cross-section of the first connecting hole 424 is elliptical, and accordingly, the insertion end of the first plug 441 is also elliptical. The cross-section of the second connecting hole 425 is circular, and accordingly, the insertion end of the second plug 442 is also circular, so that the first plug 441 can only be inserted into the first connecting hole 424, and the second plug 442 can only be inserted into the second connecting hole 425, thereby avoiding incorrect insertion.

[0061] In addition, the bipolar ion generator 400 used in the ion purification device of the water purifier of the present invention forms an electric field with precise dimensions after the emitter plate and the ground plate are connected to the current. Using alternating current, the electrons emitted by the emitter plate are led out of the dielectric barrier plate on the grounded side of the electric field to generate opposite-sign gas ions, which can effectively sterilize and disinfect the drinking water at the outlet of the water purifier. Under the airflow conditions of traditional single-stage ions, it can have a charging effect on particulate matter, and the bacteria attached to it will also be electrified. However, simply changing the potential of the bacteria itself will not kill the bacteria, just like a bird that falls on a high-voltage line will not be electrocuted to death because no current is formed on the bird. The opposite-sign gas ions generated by the bipolar ionizer of the present invention form a tiny current that can penetrate the cell wall of the bacteria, thereby killing the bacteria. It should be noted that the tiny current formed here is less than 1mA, which is safe for the human body.

[0062] The ion purification device for a water purifier of the present invention installs an ion sheet 410 within a bracket 300 between a fan 100 and an ion injection tube 600. The airflow generated by the fan 100 enters the bracket 300, carrying the purified ion clusters produced by the ion sheet 410 into the ion injection tube 600. These ions are then injected into the water flow within the water pipe 500 through a second through-hole 520, and then reach the drinking water outlet pipe of the water purifier. The fan 100, bracket 300, bipolar ion generator 400, and ion injection tube 600 occupy a small space and are flexible and convenient to install. The addition of the bipolar ion generator 400 further purifies the drinking water at the water purifier outlet, further ensuring water quality safety. The negative ions produced by the bipolar ion generator 400 are carried in the drinking water at the outlet, forming negative ion water that is closer to human cellular water and beneficial to health. The negative charge prevents acidification of the water, extending the shelf life of the drinking water at the outlet. In addition, the negative ion airflow injected into the drinking water outlet pipe can also cut water molecules into many small molecular clusters, making them easier for the human body to absorb and utilize. In addition, the bipolar ion generator 400 in the water purifier of the present invention facilitates the installation, maintenance, and replacement of the ion plate 410 by plugging and removably connecting the plug 440 to the ion plate 410. When the ion plate 410 fails, it is only necessary to unplug the plug 440 and replace the ion plate 410, without having to replace the power converter 450 or other circuit structures or electronic components in the water purifier.
