DETAILED DESCRIPTION

[0037] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thoroughly understood.

[0038] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0039] The present invention provides an elevator and an air purifier in the elevator car, wherein the elevator includes a car and an air purifier, and the air purifier is installed in the car. In one embodiment, the structure of the air purifier 10 is as follows: Figure 1 and Figure 2As shown, it includes a first shell 100, a bipolar ion generator 200, a bracket 300, a centrifugal fan 400 and a guide member 500, wherein the first shell 100 includes a cover 110 and a shell 120, the cover 110 is arranged on one side opening of the shell 120, a mesh first air inlet 121 is arranged on the side of the shell 120 opposite to the cover, a mesh first air outlet 111 is arranged on the cover 110, and the first air inlet 121 is connected to the first air outlet 111: the bipolar ion generator 200 is arranged in the first shell 100 near the first air outlet 111 through the bracket 300, and the bipolar ion generator 200 is used to generate ion groups with opposite charges. The centrifugal fan 400 and the guide member 500 are both arranged in the first shell 100, wherein, as shown in FIG. Figure 4 As shown, there are two centrifugal fans 400, which are located at opposite ends of the housing 120, and the guide member 500 is located between the two centrifugal fans 400. Figure 4 As shown, the centrifugal fan 400 includes a motor 410, an impeller 420, and a second air inlet 430 and a second air outlet 440 that are interconnected. The second air inlet 430 is connected to the first air inlet 121 of the first shell 100, and the second air outlet 440 is connected to the first air outlet 111 of the first shell 100. The second air inlet 430 is located between the motor 410 and the impeller 420. When the motor 410 rotates, the impeller 420 rotates along with it. The centrifugal force generated by the impeller 420 during rotation throws air out of the impeller 420. After being thrown out of the impeller 420, the air is gathered at the second air outlet 440 and discharged from the second air outlet 440. When the air in the impeller 420 is discharged, a negative pressure is formed inside the centrifugal fan 400, prompting the outside air to enter from the second air inlet 430. In this way, the ion fan can continuously drive the air to enter from the second air inlet 430 and be discharged from the second air outlet 440.

[0040] like Figure 2 and Figure 4 As shown, the guide member 500 is disposed between the second air outlets 440 of the two ion fans, and can guide the airflow from the second air outlets 440 to the bipolar ion generator 200. Figure 2 As shown, the bipolar ion generator 200 is installed in the housing 120 near the first air outlet 111 through the bracket 300. When the air purifier 10 is working, driven by the centrifugal fan 400, the airflow enters from the first air inlet 121, and the bipolar ion generator 200 releases ion groups with opposite charges. When the airflow flows through the bipolar ion generator 200, the ion group is taken out of the air purifier 10 from the first air outlet 111, thereby purifying the air in the elevator car.

[0041] It is understandable that in other embodiments, the centrifugal fan 400 may be replaced by other airflow driving components, as long as the airflow driving components can drive air to enter from the first air inlet 121 and flow out from the first air outlet 111 after passing through the bipolar ion generator 200. Figure 1 and Figure 2 In the illustrated embodiment, the cover 110 is also provided with an induction indicator light 112 for sensing the entry of passengers in the elevator car, generating an induction signal, and starting the air purifier 10 according to the sensed signal. It is understandable that in other embodiments, the induction indicator light 112 can be replaced by other induction components. By providing an induction component in the air purifier 10, the air purifier 10 can be turned on when someone is riding in the elevator, which saves energy and protects the environment, avoids unnecessary waste, and increases the service life of the ion purifier.

[0042] like Figure 2 , Figure 3 and Figure 8 As shown, the bipolar ion generator 200 includes an ion sheet 210, a plug 220 and a power converter 250. The ion sheet 210 is used to generate an ion group with opposite charges. The ion sheet 210 is set on the guide member 500 through the bracket 300. One end of the plug 220 is pluggably electrically connected to the ion sheet 210, and the other end is electrically connected to the power converter 250; the power converter 250 is used to convert electricity for the ion sheet 210. In a specific embodiment, the power converter 250 can convert 220V 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. In addition, Figure 5 It can be seen that the ion sheet 210 is installed in the first shell 100 through the bracket 300, and the power converter 250 is installed below the ion sheet 210 in the first shell 100 close to the ion sheet 210. In this way, the distance between the ion sheet 210 and the power converter 250 is shortened as much as possible to facilitate the electrical connection between the ion sheet 210 and the power converter 250 through the plug 220.

[0043] In one embodiment, the structure after the ion sheet 210 and the bracket 300 are assembled together is as follows: Figure 6 As shown, the structure after the ion sheet 210 and the bracket 300 are separated is as follows Figure 7 As shown. Figure 6 to Figure 7 As shown, the ion sheet 210 further includes a second shell 260 made of insulating material, which is disposed outside the ion sheet 210. The second shell 260 has hollow areas 600 on both sides of the ion sheet 210 to facilitate the outflow of positively and negatively charged ions. Figure 2 and Figure 3As shown, the ion sheet 210 is installed at a position of the guide member 500 close to the first air outlet 111 through two brackets 300, as shown in FIG. Figure 6 and Figure 7 As shown, the bracket 300 includes a fixedly connected fixing portion 310 and a mounting portion 320, the fixing portion 310 is used to fix the ion sheet 210 on the guide member 500, the mounting portion 320 has an internal hollow structure, and the ends of the mounting portions 320 of the two brackets 300 close to each other are respectively provided with a first mounting position 321 and a second mounting position 322. The second shell 260 of the ion sheet 210 is relatively provided with a first connecting end 261 and a second connecting end 262, the first connecting end 261 can be inserted into the first mounting position 321, and the second connecting end 262 can be inserted into the second mounting position 322, so that one ion sheet 210 can be installed in the first shell 100 through two brackets 300.

[0044] In addition, if Figure 6 , Figure 7 and Figure 8 As shown, the first connection end 261 and the second connection end 262 are both step-shaped, and the size of the end close to the bracket 300 is smaller than the size of the end away from the bracket 300. The small end of the first connection end 261 can be inserted into the first installation position 321, and the small end of the second connection end 262 can be inserted into the second installation position 322.

[0045] exist Figure 7 and Figure 8 As can be seen in FIG. 1 , the plug 220 includes a first plug 230 and a second plug 240. One end of the first plug 230 and the second plug 240 are pluggably connected to the ion sheet 210, and the other end of the first plug 230 and the second plug 240 are electrically connected to the power converter 250. The structure of the first plug 230 and the second plug 240 after being unplugged from the ion sheet 210 is as shown in FIG. Figure 8 As shown. Fig. 9It can be seen that 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 230, and the first plug 230 is connected to AC high voltage through the power converter 250. 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 240, and the second plug 240 is grounded through the power converter 250. 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 directions of the first electric field and the second electric field are opposite. The double-sided ion sheet 210 with a symmetrical structure increases the number of escaped electrons per unit time, enhances the ion airflow, and accelerates the speed of air purification. It can be understood that in other embodiments, the ion sheet 210 can also only include the first emitter plate 213, the first grounding plate 211 and the first dielectric blocking plate 212, and the first dielectric blocking plate 212 is located between the first emitter plate 213 and the first grounding plate 211. The first electric field is formed between the first emitter plate 213 and the first grounding plate 211, and the electrons are drawn from one end of the first emitter plate 213 through the middle first dielectric blocking plate 212 to the first grounding plate 211.

[0046] exist Fig. 9 In the embodiment shown, the first lead-out terminal 218 and the second lead-out terminal 219 of the ion sheet 210 are respectively located at two opposite ends of the ion sheet 210. Figure 7 As shown, the first plug 230 and the second plug 240 are pluggably connected to the opposite ends of the ion sheet 210, and the ends of the two brackets 300 away from the ion sheet 210 are respectively provided with a first lead-in port 323 and a second lead-in port 324, the first lead-in port 323 is connected to the first mounting position 321, and the second lead-in port 324 is connected to the second mounting position 322. The first plug 230 is pluggably electrically connected to the emitter plate of the ion sheet 210 through the first lead-in port 323, and the second plug 240 is pluggably electrically connected to the grounding plate of the ion sheet 210 through the second lead-in port 324. It can be understood that in other embodiments, the first lead-out terminal 218 and the second lead-out terminal 219 can be located at the same end of the ion sheet 210 close to the first mounting position 321, such as Fig.10 and Fig.11As shown, the first plug 230 and the second plug 240 are pluggably connected to the same end of the ion sheet 210. At this time, it is only necessary to open a first lead-in port 323 at the end of the bracket 300 away from the ion sheet 210. The first lead-in port 323 is connected to the first mounting position 321. The first plug 230 can be pluggably electrically connected to the emitter plate of the ion sheet 210 through the first lead-in port 323, and the second plug 240 can be pluggably electrically connected to the grounding plate of the ion sheet 210 through the first lead-in port 323. With such a design, it is only necessary to set the power converter 250 at a position close to the first lead-in port 323 to avoid winding when the second plug 240 is connected to the power converter 250.

[0047] In one embodiment, Fig.12 and Fig.13 As shown, the ion sheet 210 further includes a first electrical connector 270 and a second electrical connector 280. The first plug 230 is pluggably electrically connected to the emitter plate of the ion sheet 210 through the first electrical connector 270, and the second plug 240 is pluggably electrically connected to the grounding plate of the ion sheet 210 through the second electrical connector 280.

In a specific embodiment, one end of the first electrical connector 270 is welded together with the first lead-out terminal 218 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 230; one end of the second electrical connector 280 is welded together with the second lead-out terminal 219 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 240.

[0048] like Fig.12 As shown, the first plug 230 includes a third electrical connector 231, a first insulating member 232 and a first wire 233. The third electrical connector 231 is located in the first insulating member 232. One end of the third electrical connector 231 protrudes from the first insulating member 232 to form a first protruding end 234. The other end of the third electrical connector 231 is electrically connected to the first wire 233 in the first insulating member 232. Fig.13As shown, the second plug 240 includes a fourth electrical connector 241, a second insulating member 242, and a second wire 243. The fourth electrical connector 241 is located in the second insulating member 242, and one end of the fourth electrical connector 241 protrudes from the second insulating member 242 to form a second protruding end 244. The other end of the fourth electrical connector 241 is electrically connected to the second wire 243 in the second insulating member 242. The first protruding end 234 can be inserted into the first electrical connector 270, so that the first plug 230 can be electrically connected to the first emitter plate 213 and the second emitter plate 215; the second protruding end 244 can be inserted into the second electrical connector 280, so that the second plug 240 can be electrically connected to the first grounding plate 211 and the second grounding plate 217.

[0049] In addition, if Fig.12 As shown, a first elastic sheet 271 is disposed on the side wall of the first electrical connector 270, and the first elastic sheet 271 is inclined or bent toward the inside of the first electrical connector 270. When the first protruding end 234 is inserted into the first electrical connector 270, the first elastic sheet 271 can press the first protruding end 234, so that the first protruding end 234 can be tightly in contact with the first electrical connector 270 to achieve a stable electrical connection. Fig.13 As shown, a second spring piece 281 is provided on the side wall of the second electrical connector 280, and the second spring piece 281 is inclined or bent toward the inside of the second electrical connector 280. When the second protruding end 244 is inserted into the second electrical connector 280, the second spring piece 281 can press the second protruding end 244, so that the second protruding end 244 can be tightly in contact with the second electrical connector 280 to achieve a stable electrical connection.

[0050] In addition, for the convenience of processing, the first electrical connector 270 and the second electrical connector 280 are both made of a metal material with good conductivity, the first spring piece 271 is integrally formed with the first electrical connector 270, and the second spring piece 281 is integrally formed with the second electrical connector 280. In addition, it can be understood that in other embodiments, the end of the first electrical connector 270 connected to the first plug 230 can also be provided with other elastic structures, collectively referred to as the first elastic member, which can press the first plug 230 so that the first plug 230 can be closely contacted with the first electrical connector to achieve a stable electrical connection; the end of the second electrical connector 280 connected to the second plug 240 can also be provided with other elastic structures, collectively referred to as the second elastic member, which can press the second plug so that the second plug 240 can be closely contacted with the second electrical connector 280 to achieve a stable electrical connection.

[0051] In addition, to prevent wrong insertion, Fig.12 and Fig.13As shown, the first protruding end 234 is cylindrical or cylindrical, and the port where the first electrical connector 270 is connected to the first plug 230 is cylindrical; the second protruding end 244 is flat, and the port where the second electrical connector 280 is connected to the second plug 240 is also flat, so that the first plug 230 can only be inserted into the first electrical connector 270, and the second plug 240 can only be inserted into the second electrical connector 280. In order to further increase the recognition of the first plug 230 and the second plug 240, the outer cross-section of the first insulating member 232 is circular, and the outer cross-section of the second insulating member 242 is nearly elliptical or square.

Such a design can facilitate the installation, maintenance and replacement of the ion sheet 210. In addition, in some embodiments, the other ends of the first plug 230 and the second plug 240 are also pluggable and electrically connected to the power converter 250. Such a design makes it convenient to select or replace plugs 220 of different lengths or specifications according to the specific installation positions of the ion sheet 210 and the power converter 250. When the ion sheet 210 and the power converter 250 are installed in the first housing 100, it is only necessary to consider the appropriate installation positions of the ion sheet 210 and the power converter 250. After the ion sheet 210 and the power converter 250 are installed, the length or specification of the first plug 230 and the second plug 240 are selected to be pluggable and connected between the ion sheet 210 and the power converter 250.

[0053] In addition, in one embodiment, Fig.14 As described, an advertising machine 20 is also provided in the elevator car, and the air purifier 10 can be provided in the elevator car near the advertising machine 20, or above the advertising machine 20. It is understandable that in other embodiments, the air purifier 10 can also be provided on the ceiling or in any corner of the elevator car. The bipolar ion generator 200 can share a power supply with the elevator or the advertising machine 20, or can be connected to the mains separately, and the electric control system controlling the operation of the bipolar ion generator 200 can be independent of the electric control system of the elevator or the advertising machine 20, or can be interrelated.

[0054] In addition, in one embodiment, Figures 15 to 17As shown, the ion sheet 210 includes a second shell 260 made of insulating material, and the second shell 260 includes an upper shell 263 and a lower shell 264. The second shell 260 is arranged outside the ion sheet 210, and hollow areas 600 are opened on the upper and lower sides of the ion sheet 210 on the upper and lower shells 263 and 264 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 263 and the lower shell 264 are clamped on the steps on the upper and lower sides of the third dielectric blocking plate 216, so that the surface of the second shell 260 is flush with the surface of the ion sheet 210, which makes it easier for positively and negatively charged ions with opposite signs to flow out from the hollow area 600.

[0055] The bipolar ion generator in the air purifier of the present invention forms an electric field with precise dimensions after the emitter plate and the grounding plate are connected to the current. The alternating current is used to lead the electrons emitted by the emitter plate out of the dielectric barrier plate on the grounding side of the electric field to generate gas ions of opposite signs. Due to the compact characteristics of dielectric discharge, a part of the electrons flow into the grounding plate after meeting the grounding plate to form a current, and another part of the electrons escape from the surface of the medium and meet the indoor air molecules. When the escaped electrons reach a certain rate, the oxygen molecules can be stimulated to be in an ion state, and the ionized gas can charge the particles. When the charged particles encounter the grounding electrode or the reverse polarity object, it is easy to reduce the particles in the air, convert the floating dust in the air into dust, and reduce the floating particles. At the same time, the non-equilibrium oxygen ions generated have a high kinetic energy physical impact effect, which is conducive to the decomposition of harmful volatile gas molecules under the dual effects of physical and chemical effects, and can also disinfect pathogenic microorganisms, so as to achieve the purpose of air purification and disinfection.

[0056] The elevator of the present invention and the air purifier in the car thereof, by arranging an airflow driving member and a bipolar ion generator in the first shell, when the air purifier is working, under the driving action of the airflow driving member, the airflow can carry and diffuse the positive and negative purification ions generated by the ion sheet to the entire space in the elevator car, thereby achieving a comprehensive and continuous purification effect of the entire car space, and can effectively kill the floating bacteria in the air entering and leaving the car, reduce the inhalable particulate matter in the air, decompose the TVOC in the air, eliminate odors, effectively improve the air quality in the car, and make the user more comfortable and healthy when riding the elevator. In addition, the bipolar ion generator in the air purifier of the present invention facilitates the installation, maintenance and replacement of the ion sheet by plugging and unplugging the plug to electrically connect the ion sheet. When the ion sheet fails, it is only necessary to unplug the plug and replace the ion sheet, without replacing the power converter and other circuit structures or electronic components in the air purifier.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0058] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
