DETAILED DESCRIPTION

[0034] 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.

[0035] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0036] In one embodiment, the air curtain has an outer structure as follows: Figure 1 As shown, the explosion structure of the air curtain machine is as follows Figure 2 As shown, from Figure 1 and Figure 2As can be seen in the figure, the air curtain includes a main body 100, a bipolar ion generator 200 and a bracket 300, wherein the main body 100 includes a cover 110 and a first shell 120, the cover 110 is covered on the first shell 120, a mesh air inlet 111 is provided on the cover 110, and a slender slit-shaped air outlet 121 is also provided on the first shell 120, and the bipolar ion generator 200 is arranged at the position of the air outlet 121 through the bracket 300. The structure of the air curtain with the upper cover hidden is as follows Figure 3 As shown, an electrically connected motor 122 and a wind wheel 123 are provided in the first housing 120. The motor 122 and the wind wheel 123 are electrically connected, and the motor 122 can drive the wind wheel 123 to operate, so that air flows in from the air inlet 111 and then flows out from the air outlet 121. When the air curtain is in operation, driven by the motor 122, the wind wheel 123 rotates, air flows in from the air inlet 111, and the bipolar ion generator 200 releases ion groups with opposite charges. When the air flows through the bipolar ion generator 200, the ion groups are carried out of the air curtain body 100 through the air outlet 121, thereby purifying the air in the inlet and outlet channel below the air curtain.

[0037] from Figure 1-3 As can be seen in the figure, since the air curtain machine's air outlet 121 is in the shape of a long and narrow slit, in order to enable the air curtain machine to purify all the covered areas in the inlet and outlet passages, according to the size of the air curtain machine's air outlet 121, Figure 1-3 In the illustrated embodiment, two groups of bipolar ion generators are provided at the air outlet 121 of the air curtain, each group of bipolar ion generators including two bipolar ion generators 200. It is understood that in other embodiments, a longer bipolar ion generator, or another number of bipolar ion generators, may be provided at the air outlet 121 of the air curtain.

[0038] like Figure 2 、 Figure 4 and Figure 5 As shown, each bipolar ion generator 200 includes an ion sheet 210, a plug 250 and a power converter 280. The ion sheet 210 is used to generate ion groups with opposite charges. The ion sheet 210 is set at the air outlet 121 of the air curtain machine through the bracket 300. One end of the plug 250 is electrically connected to the ion sheet 210 in a pluggable manner, and the other end is electrically connected to the power converter 280; the power converter 280 is used to convert electricity for the ion sheet 210. Figure 2 and Figure 3It can be seen that the air curtain machine also includes an ionizer power box 400. The ionizer power box 400 is arranged on the side panel 124 on the side of the air outlet 121 in the first shell 120. The power converters 280 of all bipolar ion generators 200 are arranged in the ionizer power box 400. The power converter 280 is used to convert the mains electricity into the power required by the ion plate 210. In a specific embodiment, the power converter 280 can convert the 220v mains electricity into the AC high voltage electricity required by the ion plate 210. The voltage range of the high voltage electricity is generally 1000v-3000v. In addition, a switching power supply 410 is also provided in the ionizer power box 400. The switching power supply 410 is used to convert the mains electricity into the power required by the power converter 280. In a specific embodiment, the switching power supply 410 can convert the 220v mains electricity into the 5V working voltage required by the power converter 280. Figure 2 and Figure 3 In the illustrated embodiment, the power converters 280 and switching power supplies 410 of all bipolar ion generators 200 are disposed within the ionizer power box 400, which can protect the electronic components within the power box from interference and damage from external factors while facilitating installation and maintenance.

[0039] In addition, Figure 3 As can be seen, the ion sheet 210 is installed below the side panel 124 on the side of the air outlet 121 in the first shell 120 through the bracket 300, and the ionizer power box 400 is arranged above the same side panel 124 on the side of the air outlet 121 in the first shell 120. This arrangement can shorten the distance between the ion sheet 210 and the power converter 280 as much as possible, so as to facilitate the electrical connection between the ion sheet 210 and the power converter 280 through the plug 250.

[0040] The structure of the ion plate 210 of the single-group bipolar ion generator 200 connected to the bracket 300 is as follows: Figure 4 As shown, the structure of the ion plate 210 of the single-group bipolar ion generator 200 after being disassembled from the bracket 300 is as follows Figure 5 As shown, the structures of the ion sheet 210 of a single bipolar ion generator 200 before and after connection with the plug 250 are respectively as shown in FIG. Figure 6 、 Figure 7 As shown, the structure of the ion plate 210 of a single bipolar ion generator 200 is as follows Figure 8 As shown. Figures 5 and 6 As shown, the ion sheet 210 further includes a second shell 220 made of insulating material. The second shell 220 is disposed 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 ions. Figure 4 and Figure 5As shown, an ion sheet 210 is installed at the air outlet 121 of the air curtain machine through two brackets 300, as shown in FIG. Figure 5 As shown, the bracket 300 includes a fixedly connected fixing plate 310 and a mounting plate 320. The fixing plate 310 is used to be fixedly connected to the side plate 124 of the air curtain machine outlet 121 through fasteners. The mounting plate 320 has an internal hollow structure. The ends of the mounting plates 320 of the two brackets 300 that are close to each other are respectively provided with a first mounting position 321 and a second mounting position 322. The second shell 220 of the ion plate 210 is relatively provided with a first connecting end 221 and a second connecting end 222. The first connecting end 221 can be inserted into the first mounting position 321, and the second connecting end 222 can be inserted into the second mounting position 322, so that an ion plate 210 is installed at the air curtain machine outlet 121 through two brackets 300.

[0041] In addition, if Figure 6 As shown, the first connection end 221 and the second connection end 222 are both stepped, with the end closer to the bracket 300 being smaller than the end farther away from the bracket 300. The smaller end of the first connection end 221 can be inserted into the first mounting position 321, and the smaller end of the second connection end 222 can be inserted into the second mounting position 322. Figure 4 and Figure 5 As shown, the bracket 300 between two adjacent ion sheets 210 has two installation positions that are arranged opposite to each other, and are used to connect with the two adjacent ion sheets 210 respectively.

[0042] exist Figure 5-Figure 7 As can be seen in FIG, the plug 250 includes a first plug 260 and a second plug 270, and the ion sheet 210 is electrically connected to the power converter 280 via the first plug 260 and the second plug 270. Figure 8As 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 barrier plate 212, a first emitter plate 213, a second dielectric barrier plate 214, a second emitter plate 215, a third dielectric barrier 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 260, and the first plug 260 is connected to the AC high voltage through the power converter 280. The first grounding plate 211 and the second grounding plate 217 form a second lead-out terminal 219 at the same end of the ion sheet 210, and the second lead-out terminal 219 can be electrically connected to the second plug 270, and the second plug 270 is grounded through the power converter 280. 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.

[0043] exist Figure 8 In the embodiment shown, the first lead-out terminal 218 and the second lead-out terminal 219 are both located at the same end of the ion sheet 210. Therefore, the first plug 260 and the second plug 270 are pluggably disposed at the same end of the ion sheet 210. Figure 6 and Figure 7 When two ion sheets 210 are placed adjacent to each other, as shown in FIG. Figure 5 As shown, the plugs 250 of the two ion sheets 210 are both arranged at the right end of the ion sheet 210, that is, the plugs 250 of the two ion sheets 210 are not arranged adjacent to each other. This design can facilitate the electrical connection of the plugs 250 of each ion sheet 210 with the corresponding power converter 280, avoiding confusion or tangling. In addition, Figure 5As shown, two adjacent ion sheets 210 are installed and fixed by three brackets 300, and the plugs 250 of the two adjacent ion sheets 210 are both arranged at the right end of the ion sheet 210, that is, the plugs 250 of the two adjacent ion sheets 210 are both arranged at the end close to the first mounting position 321. Therefore, a lead-in opening 323 is opened at the end of the middle bracket 300 and the right bracket 300 away from the ion sheet 210, and the lead-in opening 323 is connected to the first mounting position 321. A through hole (not shown in the figure) is opened at a position corresponding to the lead-in opening 323 on the side panel 124 of the air outlet 121. One end of the first plug 260 is electrically connected to the power converter 280, and the other end is pluggable and electrically connected to the emitter plate of the ion sheet 210 through the through hole and the lead-in opening 323. One end of the second plug 270 is electrically connected to the power converter 280, and is pluggable and electrically connected to the grounding plate of the ion sheet 210 through the through hole and the lead-in opening 323.

[0044] In one embodiment, Figure 9 As shown, the ion sheet 210 further includes a first electrical connector 230 and a second electrical connector 240. The first plug 260 is pluggably electrically connected to the emitter plate of the ion sheet 210 through the first electrical connector 230, and the second plug 270 is pluggably electrically connected to the ground plate of the ion sheet 210 through the second electrical connector 240. One end of the first electrical connector 230 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 260. The other end of the first plug 260 is connected to the AC high voltage power through the power converter 280. One end of the second electrical connector 240 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 270. The other end of the second plug 270 is connected to the ground wire through the power converter 280. In a specific embodiment, one end of the first electrical connector 230 is welded together with 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 with the first plug 260; one end of the second electrical connector 240 is welded together with 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 with the second plug 270.

[0045] like Figure 9As shown, the first plug 260 includes a third electrical connector 261, a first insulating member 262, and a first conductive wire 263. The third electrical connector 261 is located within the first insulating member 262. One end of the third electrical connector 261 protrudes from the first insulating member 262 to form a first protruding end 264. The other end of the third electrical connector 261 is electrically connected to the first conductive wire 263 within the first insulating member 262. As shown in FIG9 , the second plug 270 includes a fourth electrical connector 271, a second insulating member 272, and a second conductive wire 273. The fourth electrical connector 271 is located within the second insulating member 272. One end of the fourth electrical connector 271 protrudes from the second insulating member 272 to form a second protruding end 274. The other end of the fourth electrical connector 271 is electrically connected to the second conductive wire 273 within the second insulating member 272. The first protruding end 264 can be inserted into the first electrical connector 230, so that the first plug 260 can be electrically connected to the first emitter plate 213 and the second emitter plate 215; the second protruding end 274 can be inserted into the second electrical connector 240, so that the second plug 270 can be electrically connected to the first grounding plate 211 and the second grounding plate 217.

[0046] In addition, if Figure 10 As shown, a first spring piece 231 is provided on the side wall of the first electrical connector 230. The first spring piece 231 is inclined or bent toward the interior of the first electrical connector 230. When the first protruding end 264 is inserted into the first electrical connector 230, the first spring piece 231 can press the first protruding end 264, so that the first protruding end 264 can be in close contact with the first electrical connector 230 to achieve a stable electrical connection. Similarly, Figure 11 As shown, a second spring piece 241 is provided on the side wall of the second electrical connector 240, and the second spring piece 241 is inclined or bent toward the inside of the second electrical connector 240. When the second protruding end 274 is inserted into the second electrical connector 240, the second spring piece 241 can press the second protruding end 274, so that the second protruding end 274 can be in close contact with the second electrical connector 240 to achieve a stable electrical connection.

[0047] In addition, for ease of processing, the first electrical connector 230 and the second electrical connector 240 are both made of a metal material with good electrical conductivity. The first spring piece 231 is integrally formed with the first electrical connector 230, and the second spring piece 241 is integrally formed with the second electrical connector 240. In addition, it is understandable that in other embodiments, the end of the first electrical connector 230 connected to the first plug 260 may be provided with other elastic structures, collectively referred to as first elastic members, which can press against the first plug 260 so that the first plug 260 can closely contact the first electrical connector to achieve a stable electrical connection; the end of the second electrical connector 240 connected to the second plug 270 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 270 can closely contact the second electrical connector 240 to achieve a stable electrical connection.

[0048] In addition, to prevent incorrect insertion, Figure 9 As shown, the first protruding end 264 is cylindrical or cylindrical, and the port where the first electrical connector 230 connects to the first plug 260 is cylindrical; the second protruding end 274 is flat, and the port where the second electrical connector 240 connects to the second plug 270 is also flat, so that the first plug 260 can only be inserted into the first electrical connector 230, and the second plug 270 can only be inserted into the second electrical connector 240. In order to further enhance the identification of the first plug 260 and the second plug 270, the outer cross-section of the first insulating member 262 is circular, and the outer cross-section of the second insulating member 272 is nearly elliptical or square.

[0049] exist Figure 9 In the illustrated embodiment, the first plug 260 is pluggably electrically connected to the first electrical connector 230 , and the second plug 270 is pluggably electrically connected to the second electrical connector 240 . This design facilitates installation, maintenance, and replacement of the ion sheet 210 . In addition, in some embodiments, one end of the first plug 260 is pluggable electrically connected to the first electrical connector 230, and the other end is also pluggable electrically connected to the power converter 280. One end of the second plug 270 is pluggable electrically connected to the second electrical connector 240, and the other end is also pluggable electrically connected to the power converter 280. This design makes it convenient to select or replace plugs 250 of different lengths or specifications according to the specific installation positions of the ion sheet 210 and the power converter 280. When installing the ion sheet 210 and the power converter 280 at the air outlet 121 of the air curtain machine, it is only necessary to consider the appropriate installation position of the ion sheet 210 and the power converter 280. After the ion sheet 210 and the power converter 280 are installed, the length or specification of the first plug 260 and the second plug 270 are selected to be pluggable and connected between the ion sheet 210 and the power converter 280.

[0050] In addition, in one embodiment, the bipolar ion generator 200 can share a power supply with the air curtain main body 100, or can be connected to the mains electricity separately. The electronic control system that controls the operation of the bipolar ion generator 200 can be independent of or interconnected with the electronic control system of the air curtain. In another embodiment, a pneumatic relay for detecting wind force can be installed at the air curtain outlet 121. When air flow is detected, the pneumatic relay controls the ion plate 210 to produce ions, thereby achieving automatic control, avoiding ineffective operation of the bipolar ion generator 200, and saving energy. It is understood that when the electronic control system of the bipolar ion generator 200 is connected to the electronic control system of the air curtain, there is no need to load the pneumatic relay.

[0051] Additionally, in one embodiment, Figures 12 to 14 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 223 and a lower shell 224. The second shell 220 is arranged on the outside of the ion sheet 210. The upper shell 223 and the lower shell 224 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 223 and the lower shell 224 are clamped on the steps on the upper and lower sides of the second 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.

[0052] The bipolar ion generator in the air curtain machine 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, generating gas ions of opposite signs. Due to the dense characteristics of dielectric discharge, some electrons flow into the grounding plate after encountering it to form a current, while some electrons escape from the surface of the dielectric and encounter indoor air molecules. When the escaping electrons reach a certain rate, they can stimulate oxygen molecules to ionize, ionize the gas and charge the particles. If the charged particles encounter the grounding electrode or an object of opposite polarity, they can easily reduce the particles in the air, converting the floating dust in the air into dust, reducing the floating particles. At the same time, the non-equilibrium oxygen ions generated have a high kinetic energy physical impact effect. Under the dual action of physical and chemical action, they are conducive to the decomposition of harmful volatile gas molecules and can also disinfect pathogenic microorganisms, achieving the purpose of air purification and disinfection.

[0053] The air curtain machine of the present invention sets a bipolar ion generator at the air outlet position. When the air curtain machine is working, the airflow can carry and diffuse the positive and negative purification ions generated by the ion sheet to the entire inlet and outlet channel below the air curtain machine, thereby achieving a comprehensive and continuous purification effect on the entire inlet and outlet channel. The air curtain machine and the air purifier are integrated into one, which can effectively kill the floating bacteria in the air of the inlet and outlet channel, reduce the inhalable particulate matter in the air, decompose the TVOC in the air, eliminate odors, and ensure the air supply safety of the air curtain machine. In addition, the bipolar ion generator in the air curtain machine of the present invention facilitates the installation, maintenance and replacement of the ion sheet by plugging and electrically connecting the plug to the ion sheet. When the ion sheet fails, it is only necessary 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 air curtain machine.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0055] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
