In a specific embodiment, as Figure 4 As shown, the airflow driving member 300 is a fan, including a motor 310 and a fan blade 320. The motor 310 can drive the fan blade 320 to rotate, thereby driving air to enter from the air inlet 110, pass through the bipolar ion generator 200 and then flow out from the air outlet 120.

[0041] In addition, if Figures 1 to 4 As shown, the first shell 100 is flat and located at the inner top of the cabinet 10. The first shell 100 includes a detachably connected upper shell 130, a middle shell 140 and a lower shell 150. The upper shell 130 and the lower shell 150 are arranged relative to each other, and the middle shell 140 is located between the upper shell 130 and the lower shell 150. The air inlet 110 is annular and located around the upper shell 130. The air outlet 120 is annular and located in the slit between the lower shell 150 and the middle shell 140. The annular arrangement of the air inlet 110 and the air outlet 120 can increase the air intake and air outlet volume. It can be understood that in other embodiments, the air inlet 110 can also be located in the slit between the upper shell 130 and the middle shell 140 or other positions, and the air outlet 120 can also be located in other positions such as the lower shell 150. In addition, as Figure 2 As shown, a fixing plate 131 is fixedly provided on one side of the upper shell 130 away from the middle shell 140 , and screw fixing holes are provided on the fixing plate 131 for fixing the purifier 20 on the cabinet 10 .

[0042] like Figure 5 and Figure 6As shown, a bracket 400 is provided in the first shell 100, and the ion sheet 210 is provided in the first shell 100 through the bracket 400. The bracket 400 includes an upper bracket and a lower bracket. The upper bracket 400 includes a first upper bracket 410 and a second upper bracket 420, which are respectively fixed at the opposite ends of the middle shell 140 close to the lower shell 150; the lower bracket 400 includes a first lower bracket 430 and a second lower bracket 440, which are respectively fixed at the opposite ends of the lower shell 150 close to the middle shell 140; the first upper bracket 410 and the first lower bracket 430 can cooperate with each other to fix one end of the ion sheet 210, and the second upper bracket 420 and the second lower bracket 440 can cooperate with each other to fix the other end of the ion sheet 210. As shown Figure 2 and Figure 5 As shown, the middle shell 140 is arranged in a ring shape between the upper shell 130 and the lower shell 150, and the middle shell 140 and the bracket 400 both have a hollow structure. The airflow driving component 300 is located between the upper shell 130 and the middle shell 140, the power converter 260 is located in the middle shell 140, and the plug 230 is located in the bracket 400. A lead-in port is provided at one end of the bracket 400 away from the ion sheet 210, or, the end of the bracket 400 away from the ion sheet 210 is connected to the middle shell 140, one end of the plug 230 is electrically connected to the ion sheet 210 in a pluggable manner, and the other end is electrically connected to the power converter 260 through the lead-in port.

[0043] The power converter 260 is used to convert the mains electricity into the power required by the ion sheet 210. In a specific embodiment, the power converter 260 can convert the mains electricity into the AC high voltage electricity required by the ion sheet 210. The voltage range of the high voltage electricity is generally 1000V-4000V. Figure 4 It can be seen that a switching power supply 270 is provided in the middle shell 140 at a position opposite to the power converter 260. The switching power supply 270 is used to convert the mains electricity into the power required by the power converter 260. In a specific embodiment, the switching power supply 270 can convert the 220V mains electricity into the 5V operating voltage required by the power converter 260. Figure 5 As can be seen, the ion sheet 210 is suspended and installed in the first shell 100 near the air outlet 120 through the bracket 400, and the power converter 260 is arranged in the middle shell 140 near the upper shell 130. Such an arrangement can, on the one hand, make full use of the space in the first shell 100, and on the other hand, shorten the distance between the ion sheet 210 and the power converter 260 as much as possible, so as to facilitate the electrical connection between the ion sheet 210 and the power converter 260 through the plug 230.

[0044] In one embodiment, the specific structure of the ion plate 210 is as follows: Figure 7 As shown, the structure after the plug 230 is connected to the ion plate 210 is as follows Figure 8As shown, the structure after the plug 230 is unplugged from the ion plate 210 is as follows Figure 9 As shown, from Figure 8 and Figure 9 As can be seen in the figure, the ion sheet 210 also includes a second shell 220 made of insulating material. The second shell 220 is arranged outside the ion sheet 210. The second shell 220 has hollow areas 500 on both sides of the ion sheet 210 to facilitate the outflow of positively and negatively charged ion groups. The plug 230 includes a first plug 240 and a second plug 250. The first plug 240 and the second plug 250 are respectively connected to the opposite ends of the ion sheet 210 in a pluggable manner. Figure 7 As can be seen in the figure, the ion sheet 210 is a layered rectangle, and the ion sheet 210 includes a first grounding plate 211, a first dielectric blocking plate 212, a first emitter plate 213, a second dielectric blocking plate 214, a second emitter plate 215, a third dielectric blocking plate 216 and a second grounding plate 217 from one side to the other. The first emitter plate 213 and the second emitter plate 215 form a first lead-out terminal 218 at one end of the ion sheet 210, and the first lead-out terminal 218 can be electrically connected to the first plug 240, and the first plug 240 is connected to AC high voltage through the power converter 260. The first grounding plate 211 and the second grounding plate 217 form a second lead-out terminal 219 at the other end of the ion sheet 210, and the second lead-out terminal 219 can be electrically connected to the second plug 250, and the second plug is grounded through the power converter 260. The first emitter plate 213 and the first grounding plate 211 form a first electric field, and the second emitter plate 215 and the second grounding plate 217 form a second electric field. The first electric field and the second electric field are in opposite directions. The double-sided ion plate 210 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 understood that in other embodiments, the ion plate 210 can also include only the first emitter plate 213, the first grounding plate 211, and the first dielectric barrier plate 212, wherein the first dielectric barrier plate 212 is located between the first emitter plate 213 and the first grounding plate 211, and a first electric field is formed between the first emitter plate 213 and the first grounding plate 211, so that electrons are drawn from one end of the first emitter plate 213 through the middle first dielectric barrier plate 212 to the first grounding plate 211.

[0045] exist Figure 7 In the embodiment shown, the first lead-out end 218 and the second lead-out end 219 of the ion sheet 210 are located at opposite ends of the ion sheet 210, respectively. Figure 8 and Figure 9 As shown, the first plug 240 and the second plug 250 are pluggably connected to the opposite ends of the ion sheet 210. It is understood that in other embodiments, the first lead-out end 218 and the second lead-out end 219 can be located at the same end of the ion sheet 210, such as Figure 10 and Figure 11 As shown, the first plug 240 and the second plug 250 are pluggably connected to the same end of the ion plate 210. With this design, it is only necessary to set the power converter 260 at a position close to the first plug 240 and the second plug 250. On the one hand, the length of the first plug 240 and the second plug 250 can be shortened. On the other hand, it is convenient to avoid tangling when the first plug 240 or the second plug 250 is connected to the power converter 260.

[0046] In one embodiment, Figure 12 and Figure 13 As shown, the ion sheet 210 further includes a first electrical connector 221 and a second electrical connector 223. The first plug 240 is pluggably electrically connected to the emitter plate of the ion sheet 210 via the first electrical connector 221, and the second plug 250 is pluggably electrically connected to the ground plate of the ion sheet 210 via the second electrical connector 223. One end of the first electrical connector 221 is electrically connected to the first lead-out terminal 218, and the other end is pluggably electrically connected to one end of the first plug 240. The other end of the first plug 240 is connected to an AC high voltage power supply via a power converter 260. One end of the second electrical connector 223 is electrically connected to the second lead-out terminal 219, and the other end is pluggably electrically connected to one end of the second plug 250. The other end of the second plug 250 is connected to a ground wire via the power converter 260. In a specific embodiment, one end of the first electrical connector 221 is welded to the first lead-out end 218 by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used for a pluggable electrical connection to the first plug 240; one end of the second electrical connector 223 is welded to the second lead-out end 219 by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used for a pluggable electrical connection to the second plug 250.

[0047] like Figure 12As shown, the first plug 240 includes a third electrical connector 241, a first insulating member 242, and a first conductive wire 243. The third electrical connector 241 is located within the first insulating member 242. One end of the third electrical connector 241 protrudes from the first insulating member 242 to form a first protruding end 244. The other end of the third electrical connector 241 is electrically connected to the first conductive wire 243 within the first insulating member 242. As shown in FIG. 14 , the second plug 250 includes a fourth electrical connector 251, a second insulating member 252, and a second conductive wire 253. The fourth electrical connector 251 is located within the second insulating member 252. One end of the fourth electrical connector 251 protrudes from the second insulating member 252 to form a second protruding end 254. The other end of the fourth electrical connector 251 is electrically connected to the second conductive wire 253 within the second insulating member 252. The first protruding end 244 can be inserted into the first electrical connector 221, so that the first plug 240 can be electrically connected to the first emitter plate 213 and the second emitter plate 215; the second protruding end 254 can be inserted into the second electrical connector 223, so that the second plug 250 can be electrically connected to the first grounding plate 211 and the second grounding plate 217.

[0048] In addition, as shown in FIG14 , a first spring piece 222 is provided on the side wall of the first electrical connector 221. The first spring piece 222 is inclined or bent toward the inside of the first electrical connector 221. When the first protruding end 244 is inserted into the first electrical connector 221, the first spring piece 222 can press the first protruding end 244 so that the first protruding end 244 can be in close contact with the first electrical connector 221 to achieve a stable electrical connection. Similarly, Figure 15 As shown, a second spring piece 224 is provided on the side wall of the second electrical connector 223, and the second spring piece 224 is inclined or bent toward the inside of the second electrical connector 223. When the second protruding end 254 is inserted into the second electrical connector 223, the second spring piece 224 can press the second protruding end 254, so that the second protruding end 254 can be in close contact with the second electrical connector 223 to achieve a stable electrical connection.

[0049] In addition, for ease of processing, the first electrical connector 221 and the second electrical connector 223 are both made of a metal material with good electrical conductivity. The first spring piece 222 is integrally formed with the first electrical connector 221, and the second spring piece 224 is integrally formed with the second electrical connector 223. In addition, it is understood that in other embodiments, the end of the first electrical connector 221 connected to the first plug 240 may be provided with other elastic structures, collectively referred to as first elastic members, which can press against the first plug 240 so that the first plug 240 can closely contact the first electrical connector to achieve a stable electrical connection; the end of the second electrical connector 223 connected to the second plug 250 may be provided with other elastic structures, collectively referred to as second elastic members, which can press against the second plug so that the second plug 250 can closely contact the second electrical connector 223 to achieve a stable electrical connection.

[0050] In addition, to prevent incorrect insertion, Figure 12 and Figure 13 As shown, the first protruding end 244 is cylindrical or cylindrical, and the port where the first electrical connector 221 connects to the first plug 240 is cylindrical; the second protruding end 254 is flat, and the port where the second electrical connector 223 connects to the second plug 250 is also flat. This ensures that the first plug 240 can only be inserted into the first electrical connector 221, and the second plug 250 can only be inserted into the second electrical connector 223. To further enhance the identification of the first plug 240 and the second plug 250, the outer cross-section of the first insulating member 242 is circular, and the outer cross-section of the second insulating member 252 is nearly elliptical or square.

[0051] exist Figure 12 and Figure 13 In the illustrated embodiment, the first plug 240 is pluggably electrically connected to the first electrical connector 221 , and the second plug 250 is pluggably electrically connected to the second electrical connector 223 . This design facilitates installation, maintenance, and replacement of the ion sheet 210 . In addition, in some embodiments, one end of the first plug 240 is pluggable electrically connected to the first electrical connector 221, and the other end is also pluggable electrically connected to the power converter 260. One end of the second plug 250 is pluggable electrically connected to the second electrical connector 223, and the other end is also pluggable electrically connected to the power converter 260. Such a design makes it convenient to select or replace plugs 230 of different lengths or specifications according to the specific installation positions of the ion plate 210 and the power converter 260. When installing the ion plate 210 and the power converter 260 at the air outlet 120 of the cross flow fan, it is only necessary to consider the appropriate installation positions of the ion plate 210 and the power converter 260. After the ion plate 210 and the power converter 260 are installed, the length or specification of the first plug 240 and the second plug 250 are selected to be pluggable and connected between the ion plate 210 and the power converter 260.

[0052] In addition, in one embodiment, the bipolar ionizer 200 can share a power supply with the airflow driver 300, or can be connected to the mains electricity separately. The electronic control system that controls the operation of the bipolar ionizer 200 can be independent of or interconnected with the electronic control system of the airflow driver 300. In another embodiment, a pneumatic relay for detecting wind force can be installed in the air duct of the purifier 20. When air flow is detected, the pneumatic relay controls the ionizing plate 210 to produce ions, thereby achieving automatic control, preventing the bipolar ionizer 200 from operating ineffectively and saving energy. It is understood that when the electronic control system of the bipolar ionizer 200 is interconnected with the electronic control system of the airflow driver 300, the pneumatic relay does not need to be loaded.

[0053] Additionally, in one embodiment, Figures 16 to 18 As shown, the ion sheet 210 includes a second shell 220 made of an insulating material, and the second shell 220 includes an upper shell 225 and a lower shell 226. The second shell 220 is arranged on the outside of the ion sheet 210. The upper shell 225 and the lower shell 226 are provided with hollow areas 500 on the upper and lower sides of the ion sheet 210 to facilitate the outflow of oppositely charged ion groups with positive and negative charges. The ion sheet 210 includes, from one side to the other, a first grounding electrode plate 211, a first dielectric blocking plate 212, a first emitter plate 213, a second dielectric blocking plate 214, a second emitter plate 215, a third dielectric blocking plate 216 and a second grounding electrode plate 217. The first dielectric blocking plate 212 and the third dielectric blocking plate 216 are smaller in width than the second dielectric blocking plate 214. Steps are formed between the first dielectric blocking plate 212 and the second dielectric blocking plate 214 and between the third dielectric blocking plate 216 and the second dielectric blocking plate 214. The upper shell 253 and the lower shell 254 are clamped on the steps on the upper and lower sides of the third dielectric blocking plate 214, so that the surface of the second shell 220 is flush with the surface of the ion sheet 210, which makes it easier for the positively and negatively charged ion groups to flow out from the hollow area 500.

[0054] The bipolar ion generator in the cabinet of the present invention forms an electric field with precise dimensions after the emitter plate and the grounding 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 kill bacteria in the cabinet and purify the air inside the cabinet. 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 generated here is less than 1mA, which is safe for the human body. In addition, the bipolar ion generator in the cabinet of the present invention can stimulate oxygen molecules to be in an ionic state when the escaped electrons reach a certain rate, and the ionized gas can charge the particulate matter. If the charged particulate matter encounters a grounding electrode or a reverse polarity object, it is easy to reduce the particulate matter in the indoor air, convert the floating dust in the air into settled dust, and reduce the floating particulate matter. At the same time, the non-equilibrium oxygen ions generated also have a high-kinetic energy physical impact effect, which is beneficial to the decomposition of harmful volatile gas molecules under the dual action of physical and chemical effects, and can also disinfect pathogenic microorganisms, thereby achieving the purpose of air purification and disinfection.

[0055] The cabinet with a purification function of the present invention, by rationally setting the structure of the purifier, makes the purifier occupy a small space and is flexible and convenient to install. After the purifier is installed, it can effectively and continuously and actively disinfect and sterilize the interior of the cabinet, eliminate odors, and prevent bacterial growth, making the cabinet cleaner and healthier, and can be used with confidence even when stored for a long time. In addition, the bipolar ion generator in the cabinet of the present invention facilitates the installation, maintenance and replacement of the ion plate by plugging and removably connecting the plug to the ion plate. When the ion plate fails, it is only necessary to unplug the plug and replace the ion plate, without the need to replace the power converter and other circuit structures or electronic components in the purifier.
