[0036] To facilitate understanding of the present invention, the present invention will be described more fully below with reference to the accompanying drawings. The accompanying drawings illustrate preferred embodiments of the present invention. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present disclosure.

[0038] In one embodiment, a simplified schematic diagram of a vertical elevator is shown as follows: Figure 1As shown, it includes a car 100, a ventilation device 200, a bipolar ion generator 300 and a bracket 400, wherein the car 100 has a first air inlet 110, the ventilation device 200 has an air outlet 210 and a second air inlet 220 that are interconnected, the second air inlet 220 is connected to the outside atmosphere, and the air outlet 210 is connected to the first air inlet 110 of the car 100, and the ventilation device 200 is used to ventilate the car 100; the bipolar ion generator 300 is set at the air outlet 210 position of the ventilation device 200 through the bracket 400, and the ion generator is used to generate ion groups with opposite charges. When the vertical elevator is working, the ventilation device 200 and the bipolar ion generator 300 are both working, the air flow enters from the second air inlet 220, and the bipolar ion generator 300 releases ion groups with opposite charges. When the air flow passes through the bipolar ion generator 300, the ion groups are brought from the first air inlet 110 of the car 100 to the interior of the car 100, thereby purifying the air inside the car 100. It should be noted that Figure 1 In the embodiment shown, the ventilation device 200 is used to ventilate the car 100, so that the elevator has an air duct, which includes the second air inlet 220 and the air outlet 210 of the ventilation device 200 and the first air inlet 110 of the car 100. Figure 1 In the embodiment shown, the bipolar ion generator 300 is installed at the air outlet 210 of the ventilation device 200 through the bracket 400. It is understood that in other embodiments, the bipolar ion generator 300 can also be installed at the second air inlet 220 of the car 100 through the bracket 400. Figure 1 In the illustrated embodiment, the air outlet 210 of the ventilation device 200 can be directly connected to the first air inlet 110 of the car 100, and the bipolar ion generator 300 is installed at the first air inlet 110 of the car 100 or the air outlet 210 of the ventilation device 200 via a bracket 400. In another embodiment, a connecting duct can be further provided between the air outlet 210 and the first air inlet 110 of the ventilation device 200. The air duct of the elevator includes the second air inlet 220 of the ventilation device 200, the air outlet 210, the first air inlet 110 of the car 100, and the connecting duct between the air outlet 210 and the first air inlet 110. The bipolar ion generator 300 can also be installed in the connecting duct between the air outlet 210 and the first air inlet 110 via a bracket 400.

[0039] In a specific embodiment, the ventilation device 200 is a cross-flow fan, and the structure of the cross-flow fan is as follows: Figure 2 and Figure 3As shown, it includes a first shell 230 and an electrically connected motor 240 and a wind wheel 250. The first shell 230 is provided with a meshed second air inlet 220 and an air outlet 210. The motor 240 can drive the wind wheel 250 to work, so that air can enter from the second air inlet 220 of the ventilation device 200, and enter the interior of the elevator car 100 through the air outlet 210 of the ventilation device 200 and the first air inlet 110 of the elevator. In addition, as Figure 2 and Figure 3 As shown, an isolation plate 260 is further provided on the first housing 230. The isolation plate 260 is used to isolate the second air inlet 220 from the air outlet 210. The bipolar ion generator 300 is mounted at the air outlet 210 of the cross-flow fan via a bracket 400. When the vertical elevator is in operation, the cross-flow fan and the bipolar ion generator 300 are both in operation, and air flows in from the second air inlet 220. The bipolar ion generator 300 releases ion groups with opposite charges. When the air flows through the bipolar ion generator 300, the ion groups are carried from the second air inlet 220 of the elevator car 100 to the interior of the elevator car 100, thereby purifying the air inside the elevator car 100.

[0040] It should be noted that in Figure 2 In the illustrated embodiment, the ventilation device 200 is a cross-flow fan. It is understandable that in other embodiments, the ventilation device 200 may also be an air conditioner or the like.

[0041] In one embodiment, the front structure of the cross flow fan is as follows Figure 2 As shown, the explosion structure is as Figure 3 As shown, the back structure is as Figure 4 As shown, the structure of the bipolar ion generator 300 and the bracket 400 after being assembled together is as shown in FIG. Figure 5 As shown, the structure of the bipolar ion generator 300 and the bracket 400 after being separated is as follows Figure 6 As shown. Figure 3 、 Figure 5 and Figure 6 As can be seen in FIG, the bipolar ion generator 300 includes an ion sheet 310, a plug 320 and a power converter 330. The ion sheet 310 is used to generate ion groups with opposite charges. The ion sheet 310 is set at the air outlet 210 of the cross flow fan through the bracket 400. The structures before and after the plug 320 is connected to the ion sheet 310 are as follows: Figure 7 and Figure 8 As shown, one end of the plug 320 is pluggably electrically connected to the ion sheet 310, and the other end is electrically connected to the power converter 330. The power converter 330 is used to convert the mains electricity into the power required by the ion sheet 310. In a specific embodiment, the power converter 330 can convert the 220v mains electricity into the AC high voltage electricity required by the ion sheet 310. The voltage range of the high voltage electricity is generally 1000v-3000v. Figure 3picture, Figure 4 and Figure 6 As can be seen, the power converter 330 is installed on the back of the first fixed plate 211 on the right side of the cross flow fan outlet 210, and the plug 320 is connected to the right end of the ion sheet 310. This arrangement can shorten the distance between the ion sheet 310 and the power converter 330 as much as possible, so as to facilitate the electrical connection between the ion sheet 310 and the power converter 330 through the plug 320.

[0042] like Figures 6 and 7 As shown, the ion sheet 310 further includes a second shell 340 made of insulating material. The second shell 340 is disposed outside the ion sheet 310. The second shell 340 has hollow areas 500 on both sides of the ion sheet 310 to facilitate the outflow of positively and negatively charged ions. Figure 2 As shown, the ion sheet 310 is mounted on the air outlet 210 of the cross flow fan through two brackets 400, as shown in FIG. Figure 2 and Figure 6 As shown, the bracket 400 includes a second fixed plate 410 and a mounting plate 420 that are fixedly connected. The second fixed plate 410 is provided with a fixing hole 411 for mounting the bracket 400 and the bipolar ion generator 300 between the upper plate 212 and the lower plate 213 of the cross flow fan outlet 210 via fasteners. The mounting plate 420 has an internal hollow structure. The mounting plates 420 of the two brackets 400 are respectively provided with a first mounting position 421 and a second mounting position 422 at one end close to each other. The second shell 340 of the ion sheet 310 is provided with a first connecting end 341 and a second connecting end 342 opposite to each other. The first connecting end 341 can be inserted into the first mounting position 421, and the second connecting end 342 can be inserted into the second mounting position 422, so that one ion sheet 310 can be mounted at the cross flow fan outlet 210 via two brackets 400.

[0043] In addition, if Figure 6 、 Figure 7 and Figure 8 As shown, the first connection end 341 and the second connection end 342 are both step-shaped, and the size of the end close to the bracket 400 is smaller than the size of the end away from the bracket 400. The end of the first connection end 341 with a smaller size can be inserted into the first installation position 421, and the end of the second connection end 342 with a smaller size can be inserted into the second installation position 422.

[0044] exist Figure 7 and Figure 8 As can be seen in FIG, the plug 320 includes a first plug 350 and a second plug 360, and the ion sheet 310 is electrically connected to the power converter 330 through the first plug 350 and the second plug 360. Figure 9As can be seen in the figure, the ion sheet 310 is a layered rectangle, and the ion sheet 310 includes a first grounding plate 311, a first dielectric blocking plate 312, a first emitter plate 313, a second dielectric blocking plate 314, a second emitter plate 315, a third dielectric blocking plate 316 and a second grounding plate 317 from one side to the other. The first emitter plate 313 and the second emitter plate 315 form a first lead-out terminal 318 at one end of the ion sheet 310, and the first lead-out terminal 318 can be electrically connected to the first plug 350. The first plug 350 is connected to the AC high voltage through the power converter 330. The first grounding plate 311 and the second grounding plate 317 form a second lead-out terminal 319 at the same end of the ion sheet 310, and the second lead-out terminal 319 can be electrically connected to the second plug 360. The second plug 360 is grounded through the power converter 330. The first emitter plate 313 and the first grounding plate 311 form a first electric field, and the second emitter plate 315 and the second grounding plate 317 form a second electric field. The first electric field and the second electric field are in opposite directions. Thus, the symmetrical double-sided ion plate 310 increases the number of electrons emitted per unit time, enhances the ion airflow, and accelerates the speed of air purification. It is understood that in other embodiments, the ion plate 310 may also include only the first emitter plate 313, the first grounding plate 311, and the first dielectric barrier 312. The first dielectric barrier 312 is located between the first emitter plate 313 and the first grounding plate 311. A first electric field is formed between the first emitter plate 313 and the first grounding plate 311, and electrons are drawn from one end of the first emitter plate 313 through the middle first dielectric barrier 312 to the first grounding plate 311.

[0045] exist Figure 9 In the embodiment shown, the first lead-out terminal 318 and the second lead-out terminal 319 are both located at the same end of the ion plate 310. Therefore, the first plug 350 and the second plug 360 are pluggably disposed at the same end of the ion plate 310 near the first mounting position 421. Figure 6 As shown, a lead-in port 423 is provided on the surface of the bracket 400 away from one end of the ion sheet 310, and the lead-in port 423 is connected to the first mounting position 421. A through hole (not shown in the figure) is provided at a position corresponding to the lead-in port 423 on the upper plate 212 of the cross-flow fan outlet 210. One end of the first plug 350 is electrically connected to the power converter 330, and the other end is pluggable electrically connected to the emitter plate of the ion sheet 310 through the through hole and the lead-in port 423. One end of the second plug 360 is electrically connected to the power converter 330, and is pluggable electrically connected to the ground plate of the ion sheet 310 through the through hole and the lead-in port 423.

[0046] In one embodiment, Figure 10As shown, the ion sheet 310 further includes a first electrical connector 370 and a second electrical connector 380. The first plug 350 is pluggably electrically connected to the emitter plate of the ion sheet 310 via the first electrical connector 370, and the second plug 360 is pluggably electrically connected to the ground plate of the ion sheet 310 via the second electrical connector 380. One end of the first electrical connector 370 is electrically connected to the first lead-out terminal 318, and the other end is pluggably electrically connected to one end of the first plug 350. The other end of the first plug 350 is connected to the AC high voltage power through the power converter 330. One end of the second electrical connector 380 is electrically connected to the second lead-out terminal 319, and the other end is pluggably electrically connected to one end of the second plug 360. The other end of the second plug 360 is connected to the ground wire through the power converter 330. In a specific embodiment, one end of the first electrical connector 370 is welded together with the first lead-out end 318 by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used for a pluggable electrical connection with the first plug 350; one end of the second electrical connector 380 is welded together with the second lead-out end 319 by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used for a pluggable electrical connection with the second plug 360.

[0047] like Figure 10 As shown, the first plug 350 includes a third electrical connector 351, a first insulating member 352, and a first conductive wire 353. The third electrical connector 351 is located within the first insulating member 352. One end of the third electrical connector 351 protrudes from the first insulating member 352 to form a first protruding end 354. The other end of the third electrical connector 351 is electrically connected to the first conductive wire 353 within the first insulating member 352. As shown in FIG9 , the second plug 360 includes a fourth electrical connector 361, a second insulating member 362, and a second conductive wire 363. The fourth electrical connector 361 is located within the second insulating member 362. One end of the fourth electrical connector 361 protrudes from the second insulating member 362 to form a second protruding end 364. The other end of the fourth electrical connector 361 is electrically connected to the second conductive wire 363 within the second insulating member 362. The first protruding end 354 can be inserted into the first electrical connector 370, so that the first plug 350 can be electrically connected to the first emitter plate 313 and the second emitter plate 315; the second protruding end 364 can be inserted into the second electrical connector 380, so that the second plug 360 can be electrically connected to the first grounding plate 311 and the second grounding plate 317.

[0048] In addition, as shown in FIG11 , a first spring piece 371 is provided on the side wall of the first electrical connector 370. The first spring piece 371 is inclined or bent toward the interior of the first electrical connector 370. When the first protruding end 354 is inserted into the first electrical connector 370, the first spring piece 371 can press the first protruding end 354 so that the first protruding end 354 can be in close contact with the first electrical connector 370 to achieve a stable electrical connection. Similarly, Figure 12 As shown, a second spring piece 381 is provided on the side wall of the second electrical connector 380, and the second spring piece 381 is inclined or bent toward the inside of the second electrical connector 380. When the second protruding end 364 is inserted into the second electrical connector 380, the second spring piece 381 can press the second protruding end 364, so that the second protruding end 364 can be in close contact with the second electrical connector 380 to achieve a stable electrical connection.

[0049] In addition, for ease of processing, the first electrical connector 370 and the second electrical connector 380 are both made of a metal material with good electrical conductivity. The first spring piece 371 is integrally formed with the first electrical connector 370, and the second spring piece 381 is integrally formed with the second electrical connector 380. In addition, it is understandable that in other embodiments, the end of the first electrical connector 370 connected to the first plug 350 may be provided with another elastic structure, collectively referred to as a first elastic member, which can press against the first plug 350 so that the first plug 350 can closely contact the first electrical connector to achieve a stable electrical connection; the end of the second electrical connector 380 connected to the second plug 360 may be provided with another elastic structure, collectively referred to as a second elastic member, which can press against the second plug so that the second plug 360 can closely contact the second electrical connector 380 to achieve a stable electrical connection.

[0050] In addition, to prevent incorrect insertion, Figure 10 As shown, the first protruding end 354 is cylindrical or cylindrical, and the port where the first electrical connector 370 connects to the first plug 350 is cylindrical; the second protruding end 364 is flat, and the port where the second electrical connector 380 connects to the second plug 360 is also flat. This ensures that the first plug 350 can only be inserted into the first electrical connector 370, and the second plug 360 can only be inserted into the second electrical connector 380. To further enhance the identification of the first plug 350 and the second plug 360, the outer cross-section of the first insulating member 352 is circular, and the outer cross-section of the second insulating member 362 is nearly elliptical or square.

[0051] exist Figure 10In the illustrated embodiment, the first plug 350 is pluggably electrically connected to the first electrical connector 370 , and the second plug 360 is pluggably electrically connected to the second electrical connector 380 . This design facilitates installation, maintenance, and replacement of the ion sheet 310 . In addition, in some embodiments, one end of the first plug 350 is pluggable electrically connected to the first electrical connector 370, and the other end is also pluggable electrically connected to the power converter 330. One end of the second plug 360 is pluggable electrically connected to the second electrical connector 380, and the other end is also pluggable electrically connected to the power converter 330. Such a design makes it convenient to select or replace plugs 320 of different lengths or specifications according to the specific installation positions of the ion plate 310 and the power converter 330. When installing the ion plate 310 and the power converter 330 at the air outlet 210 of the cross flow fan, it is only necessary to consider the appropriate installation positions of the ion plate 310 and the power converter 330. After the ion plate 310 and the power converter 330 are installed, the length or specification of the first plug 350 and the second plug 360 are selected to be pluggable and connected between the ion plate 310 and the power converter 330.

[0052] Furthermore, in one embodiment, the bipolar ion generator 300 can share a power supply with the vertical elevator or crossflow blower, or can be connected to the mains electricity supply independently. The electrical control system controlling the operation of the bipolar ion generator 300 can be independent of or interconnected with the electrical control system of the vertical elevator or crossflow blower. In another embodiment, a pneumatic relay for detecting wind force can be installed in the air duct of the vertical elevator. When air flow is detected, the pneumatic relay controls the ionizing plate 310 to produce ions, thereby achieving automatic control, preventing the bipolar ion generator 300 from operating ineffectively and saving energy. It is understood that when the electrical control system of the bipolar ion generator 300 is interconnected with the electrical control system of the vertical elevator, the pneumatic relay does not need to be loaded.

[0053] Additionally, in one embodiment, Figures 13 to 15As shown, the ion sheet 310 includes a second shell 340 made of insulating material, and the second shell 340 includes an upper shell 343 and a lower shell 344. The second shell 340 is arranged on the outside of the ion sheet 310. The upper shell 343 and the lower shell 344 are provided with hollow areas 500 on the upper and lower sides of the ion sheet 310 to facilitate the outflow of oppositely charged ion groups with positive and negative charges. The ion sheet 310 includes, from one side to the other, a first grounding electrode plate 311, a first dielectric blocking plate 312, a first emitter plate 313, a second dielectric blocking plate 314, a second emitter plate 315, a third dielectric blocking plate 316 and a second grounding electrode plate 317. The first dielectric blocking plate 312 and the third dielectric blocking plate 316 are smaller in width than the second dielectric blocking plate 314. Steps are formed between the first dielectric blocking plate 312 and the second dielectric blocking plate 314 and between the third dielectric blocking plate 316 and the second dielectric blocking plate 314. The upper shell 343 and the lower shell 344 are clamped on the steps on the upper and lower sides of the second dielectric blocking plate 314, so that the surface of the second shell 340 is flush with the surface of the ion sheet 310, 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 vertical elevator of the present invention forms a precisely dimensioned electric field when current is connected to the emitter plate and the grounding plate. Using alternating current, electrons emitted by the emitter plate are drawn out of the dielectric barrier plate on the grounded side of the electric field, generating opposite-sign gas ions. Due to the compact nature of dielectric discharge, some electrons encounter the grounding plate and flow into it, forming a current, while others escape from the dielectric surface and encounter indoor air molecules. When the escaping electrons reach a certain rate, they stimulate oxygen molecules to ionize, ionizing the gas and charging particulate matter. If the charged particulate matter encounters the grounding plate or an object of opposite polarity, it can easily reduce the particulate matter in the cabin air, converting airborne dust into settled dust and reducing floating particulate matter. The generated non-equilibrium oxygen ions simultaneously possess high kinetic energy, exerting a physical impact that, through both physical and chemical effects, facilitates the decomposition of harmful volatile gas molecules and also kills pathogenic microorganisms, achieving the purpose of air purification and disinfection.

[0055] The vertical elevator of the present invention is provided with a bipolar ion generator in its air duct. When the vertical elevator is working, the airflow can carry and diffuse the positive and negative purification ions generated by the ion sheet to the entire space in the car, achieving a comprehensive and continuous purification effect. The vertical elevator and the air purifier are integrated into one, which can effectively kill the floating bacteria in the air entering and leaving the car, reduce the inhalable particulate matter in the air in the car, decompose the TVOC in the air, eliminate odors, and ensure the safety of the air supply of the elevator. In addition, the bipolar ion generator in the vertical elevator of the present invention facilitates the installation, maintenance and replacement of the ion sheet by plugging and removably connecting the plug to the ion sheet. When the ion sheet fails, it only needs to unplug the plug and replace the ion sheet. There is no need to replace the power converter and other circuit structures or electronic components in the vertical elevator. In addition, the vertical elevator of the present invention has a bipolar ion generator installed in the air duct of the elevator, which makes the elevator have an active purification function. Through the air intake airflow, the air inside the car is continuously purified, the air quality in the car is improved, and the user is more comfortable and healthy when riding the elevator. In addition, the bipolar ion generator in the vertical elevator of the present invention is small in size, highly safe, has low installation and use requirements, will not "block" the elevator's air duct, and can also achieve a certain diversion effect by adjusting the installation position and angle of the bipolar ion generator.
