Detailed implementation mode

[0034] To facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. The preferred embodiments of the present invention are shown 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, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.

[0035] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "inner", "outer", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only embodiments.

[0036] In one embodiment, the structure of the fan is as shown in Figure 1 and Figure 2As shown, it includes a main body 100, a bipolar ion generator 200 and a bracket 300. Among them, an air inlet hood 110 and an air outlet hood 120 are connected to each other on the main body 100. An air inlet 111 is provided on the air inlet hood 110, and an air outlet 121 is provided on the air outlet hood 120. A middle housing 130 is provided on the side of the air inlet hood 110 facing the air outlet hood 120. A motor 131 is provided inside the middle housing 130. A fan blade 132 is provided at the end of the middle housing 130 close to the air outlet hood 120. The motor 131 can drive the fan blade 132 to work, so that air flow enters from the air inlet 111 and flows out from the air outlet 121. As Figure 2 shown, one end of the middle housing 130 where the fan blade 132 is installed is also connected to a column 140, the other end of the column 140 is connected to a base 150, and a control panel 151 is provided on the base 150 for controlling the operation of the fan. The bipolar ion generator 200 is installed inside the main body 100 between the air inlet 111 and the air outlet 121 through the bracket 300. When the fan works, under the driving action of the motor 131, air flow enters from the air inlet 111, and the bipolar ion generator 200 can release a group of ions with opposite charges. When the air flow passes through the bipolar ion generator 200, the group of ions is taken out of the fan from the air outlet 121, thereby purifying the indoor air.

[0037] Figure 2 The exploded structure of the fan shown after hiding the air outlet hood and the fan blade is as Figure 3 shown. From Figure 3 and Figure 5 it can be seen that the bipolar ion generator 200 includes ion plates 210, plugs 250 and power converters 280. The ion plates 210 are used to generate a group of ions with opposite charges. The ion plates 210 are arranged on the middle housing 130 through the bracket 300. One end of the plug 250 is electrically connected to the ion plates 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 power for the ion plates 210. From Figure 3 it can be seen that the power converter 280 is arranged inside the middle housing 130. The power converter 280 is used to convert commercial power into the power required by the ion plates 210. In a specific embodiment, the power converter 280 can convert 220v commercial power into the AC high voltage required by the ion plates 210, and the voltage range of the high voltage is generally 1000v - 3000v.

[0038] In one embodiment, the structure of the ion plates 210 and the bracket 300 assembled together is as Figure 4 shown, and the structure of the ion plates 210 and the bracket 300 after being disassembled is as Figure 5 shown. As Figure 4 and Figure 5As shown, the ion sheet 210 further includes a housing 220 made of an insulating material. The housing 220 is disposed outside the ion sheet 210. Hollow areas 400 are provided on both sides of the ion sheet 210 on the housing 220 to facilitate the outflow of positive and negative ion groups with opposite charges. As Figure 2 shown, the ion sheet 210 is mounted on the middle housing 130 near the fan blade 132 through two brackets 300. As Figure 4 and Figure 5 shown, the bracket 300 includes a fixed part 310 and a mounting part 320 that are fixedly connected. The fixed part 310 is used to fix the ion sheet 210 on the middle housing 130. A fixing hole 311 is provided at the position where the fixed part 310 is connected to the middle housing 130. Fasteners such as screws can pass through the fixing hole 311 to fixedly mount the bracket 300 on the middle housing 130. The mounting part 320 has a hollow internal structure. First mounting positions 321 and second mounting positions 322 are respectively provided at one ends of the mounting parts 320 of the two brackets 300 that are close to each other. The housing 220 of the ion sheet 210 is provided with a first connection end 221 and a second connection end 222 that are oppositely arranged. The first connection end 221 can be inserted into the first mounting position 321, and the second connection end 222 can be inserted into the second mounting position 322, so that an ion sheet 210 can be mounted on the middle housing 130 through two brackets 300.

[0039] In addition, as Figure 4 、 Figure 5 and Figure 6 shown, both the first connection end 221 and the second connection end 222 are stepped. The dimension of the end close to the bracket 300 is smaller than that of the end far 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.

[0040] In Figure 5 and Figure 6 it can be seen that the plug 250 includes a first plug 260 and a second plug 270. One ends of the first plug 260 and the second plug 270 are detachably connected to the ion sheet 210, and the other ends of the first plug 260 and the second plug 270 are electrically connected to the power converter 280. The structure after the first plug 260 and the second plug 270 are unplugged from the ion sheet 210 is as Figure 6 shown. In Figure 7As can be seen, the ion sheet 210 is in a layered rectangular shape. The ion sheet 210 sequentially includes a first grounding electrode plate 211, a first dielectric barrier plate 212, a first emission electrode plate 213, a second dielectric barrier plate 214, a second emission electrode plate 215, a third dielectric barrier plate 216, and a second grounding electrode plate 217 from one side to the other side. The first emission electrode plate 213 and the second emission electrode plate 215 form a first lead-out end 218 at one end of the ion sheet 210. The first lead-out end 218 can be electrically connected to the first plug 260. The other end of the first plug 260 is connected to an AC high voltage through a power converter 280. The first grounding electrode plate 211 and the second grounding electrode plate 217 form a second lead-out end 219 at the other end of the ion sheet 210. The second lead-out end 219 can be electrically connected to the second plug 270. The other end of the second plug 270 is grounded through a power converter 280. The first emission electrode plate 213 and the first grounding electrode plate 211 form a first electric field, and the second emission electrode plate 215 and the second grounding electrode plate 217 form a second electric field. The directions of the first electric field and the second electric field are opposite. Such a double-sided ion sheet 210 with a symmetric structure increases the number of electrons escaping per unit time, enhances the ion airflow, and speeds up the air purification rate. It can be understood that in other embodiments, the ion sheet 210 may also only include the first emission electrode plate 213, the first grounding electrode plate 211, and the first dielectric barrier plate 212. The first dielectric barrier plate 212 is located between the first emission electrode plate 213 and the first grounding electrode plate 211. A first electric field is formed between the first emission electrode plate 213 and the first grounding electrode plate 211, and electrons are led out from one end of the first emission electrode plate 213 through the middle first dielectric barrier plate 212 to the first grounding electrode plate 211.

[0041] In Figure 7 the illustrated embodiment, the first lead-out end 218 and the second lead-out end 219 of the ion sheet 210 are respectively located at opposite ends of the ion sheet 210. As Figure 5 and Figure 6 shown, the first plug 260 and the second plug 270 are respectively pluggably connected to opposite ends of the ion sheet 210. One ends of the two brackets 300 away from the ion sheet 210 are respectively provided with a first wire lead-out port 323 and a second wire lead-out port (not shown in the figure). The first wire lead-out port 323 is communicated with the first installation position 321, and the second wire lead-out port is communicated with the second installation position 322. As Figure 3As shown, a first through hole (not shown in the figure) is provided at a position on the middle shell 130 corresponding to the first lead port 323 of the bracket 300, and a second through hole 133 is provided at a position on the middle shell 130 corresponding to the second lead port of the bracket 300. The power converter 280 is disposed within the middle shell 130. One end of the first plug 260 is electrically connected to the power converter 280, and the other end is electrically connected to the emission electrode plate of the ion sheet 210 in a pluggable manner through the first through hole and the first lead port 323; one end of the second plug 270 is electrically connected to the power converter 280, and the other end is electrically connected to the grounding electrode plate of the ion sheet 210 in a pluggable manner through the second through hole 133 and the second lead port. It can be understood that in other embodiments, the first lead-out end 218 and the second lead-out end 219 may be located at the same end of the ion sheet 210 close to the first mounting position 321, such as Figure 8 and Figure 9 As shown, the first plug 260 and the second plug 270 are pluggably connected to the same end of the ion sheet 210. At this time, only the first lead port 323 needs to be opened at one end of the bracket 300 away from the ion sheet 210. Correspondingly, only the first through hole needs to be provided at a position on the middle shell 130 corresponding to the first lead port 323. The first lead port 323 is in communication with both the first through hole and the first mounting position 321. One end of the first plug 260 is electrically connected to the power converter 280, and the other end is electrically connected to the emission electrode plate of the ion sheet 210 in a pluggable manner through the first through hole and the first lead port 323; one end of the second plug 270 is electrically connected to the power converter 280, and the other end is electrically connected to the grounding electrode plate of the ion sheet 210 in a pluggable manner through the first through hole and the first lead port 323. With such a design, only the power converter 280 needs to be disposed at a position close to the first through hole, avoiding wire winding when the second plug 270 is connected to the power converter 280.

[0042] In addition, in Figure 3 As shown in the embodiment, the ion sheet 210 is disposed on the middle shell 130, the power converter 280 is disposed within the middle shell 130, the first lead port 323 and the second lead port are provided at one end of the bracket 300 away from the ion sheet 210, and the first through hole and the second through hole 133 are respectively provided at positions on the middle shell 130 corresponding to the first lead port 323 and the second lead port. With such a setting, the distance between the ion sheet 210 and the power converter 280 is minimized, facilitating the electrical connection between the ion sheet 210 and the power converter 280 through the plug 250.

[0043] In one embodiment, such as Figure 10 and Figure 11As shown, the ion sheet 210 further includes a first electrical connector 230 and a second electrical connector 240. The first plug 260 is electrically connected to the emission electrode plate of the ion sheet 210 through the first electrical connector 230 in a pluggable manner, and the second plug 270 is electrically connected to the grounding electrode plate of the ion sheet 210 through the second electrical connector 240 in a pluggable manner. One end of the first electrical connector 230 is electrically connected to the first lead-out end 218, and the other end is electrically connected to one end of the first plug 260 in a pluggable manner. The other end of the first plug 260 is connected to an AC high voltage through a power converter 280; one end of the second electrical connector 240 is electrically connected to the second lead-out end 219, and the other end is electrically connected to one end of the second plug 270 in a pluggable manner. The other end of the second plug 270 is connected to a ground wire through a power converter 280. In a specific embodiment, one end of the first electrical connector 230 and the first lead-out end 218 are welded together by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used for pluggable electrical connection with the first plug 260; one end of the second electrical connector 240 and the second lead-out end 219 are welded together by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used for pluggable electrical connection with the second plug 270.

[0044] As Figure 10 shown, the first plug 260 includes a third electrical connector 261, a first insulating member 262, and a first 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, and the other end of the third electrical connector 261 is electrically connected to the first wire 263 within the first insulating member 262. As Figure 11 shown, the second plug 270 includes a fourth electrical connector 271, a second insulating member 272, and a second wire 273. The fourth electrical connector 271 is located within the second insulating member 272, and 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 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 emission electrode plate 213 and the second emission electrode 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 electrode plate 211 and the second grounding electrode plate 217.

[0045] In addition, as Figure 10As shown, a first elastic piece 231 is provided on the side wall of the first electrical connector 230. The first elastic piece 231 inclines or bends towards the inside of the first electrical connector 230. After the first protruding end 264 is inserted into the first electrical connector 230, the first elastic piece 231 can press against 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 stable electrical connection. Similarly, as Figure 11 shown, a second elastic piece 241 is provided on the side wall of the second electrical connector 240. The second elastic piece 241 inclines or bends towards the inside of the second electrical connector 240. After the second protruding end 274 is inserted into the second electrical connector 240, the second elastic piece 241 can press against 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 stable electrical connection.

[0046] In addition, for the convenience of processing, both the first electrical connector 230 and the second electrical connector 240 are made of metal materials with good conductivity. The first elastic piece 231 is integrally formed with the first electrical connector 230, and the second elastic piece 241 is integrally formed with the second electrical connector 240. In addition, it can be understood that in other embodiments, other elastic structures can also be provided at the end of the first electrical connector 230 connected to the first plug 260, collectively referred to as the first elastic member. The first elastic member can press against the first plug 260, so that the first plug 260 can be in close contact with the first electrical connection to achieve stable electrical connection; other elastic structures can also be provided at the end of the second electrical connector 240 connected to the second plug 270, collectively referred to as the second elastic member. The second elastic member can press against the second plug, so that the second plug 270 can be in close contact with the second electrical connector 240 to achieve stable electrical connection.

[0047] In addition, to prevent misinsertion, as Figure 10 and Figure 11 shown, the first protruding end 264 is cylindrical or tubular, and the port of the first electrical connector 230 connected to the first plug 260 is tubular; the second protruding end 274 is flat, and the port of the second electrical connector 240 connected 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. And to further increase the distinguishability 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 272242 is nearly elliptical or square.

[0048] In Figure 6 and Figure 8In the illustrated embodiment, the first plug 260, the second plug 270 and the ion sheet 210 are electrically connected in a pluggable manner. Such a design facilitates the installation, maintenance and replacement of the ion sheet 210. Additionally, in some embodiments, the other ends of the first plug 260 and the second plug 270 are also electrically connected to the power converter 280 in a pluggable manner. Such a design enables the selection or replacement of 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 in the fan body 100, only the suitable installation positions of the ion sheet 210 and the power converter 280 need to be considered. After the ion sheet 210 and the power converter 280 are installed, the first plug 260 and the second plug 270 of the appropriate length or specification are then pluggably connected between the ion sheet 210 and the power converter 280.

[0049] In one embodiment, the bipolar ion generator 200 can share a power supply with the fan body 100 or can be separately connected to the mains power. The electronic control system for controlling the operation of the bipolar ion generator 200 can be independent of or related to the electronic control system of the fan body 100. In another embodiment, a pneumatic relay for detecting wind force can be installed between the air inlet 111 and the air outlet 121 of the fan. When air flow is detected, the pneumatic relay controls the ion sheet 210 to generate ions, thereby achieving automatic control, avoiding the ineffective operation of the bipolar ion generator 200, and saving electrical energy. It can be understood that when the electronic control system of the bipolar ion generator 200 is related to the electronic control system of the fan body 100, there is no need to load a pneumatic relay.

[0050] Additionally, in one embodiment, as Figures 12 to 14 shown, the ion sheet 210 includes a housing 220 made of an insulating material. The housing 220 includes an upper shell 253 and a lower shell 254. The housing 220 is disposed outside the ion sheet 210. The upper shell 253 and the lower shell 254 are each provided with a hollowed-out area 400 on both the upper and lower sides of the ion sheet 210 to facilitate the outflow of positive and negative ion groups with opposite charges. The ion sheet 210 sequentially includes a first grounding electrode plate 211, a first dielectric barrier plate 212, a first emission electrode plate 213, a second dielectric barrier plate 214, a second emission electrode plate 215, a third dielectric barrier plate 216 and a second grounding electrode plate 217 from one side to the other side. The dimensions of the first dielectric barrier plate 212 and the third dielectric barrier plate 216 in the width direction are smaller than those of the second dielectric barrier plate 214. Steps are formed between the first dielectric barrier plate and the second dielectric barrier plate, and between the third dielectric barrier plate and the second dielectric barrier plate. The upper shell 253 and the lower shell 254 are clamped on the steps on both the upper and lower sides of the third dielectric barrier plate, such that the surface of the housing 220 is flush with the surface of the ion sheet 210, making it more convenient for positive and negative ion groups with opposite charges to flow out from the hollowed-out area 400.

[0051] In the bipolar ion generator of the fan of the present invention, after the emission electrode plate and the grounding electrode plate are connected to an electric current, an electric field with precise dimensions is formed. Using alternating current, electrons emitted from the emission electrode plate are led out of the dielectric barrier plate on the grounded side of the electric field to generate gas ions of opposite signs. Due to the dense characteristics of dielectric discharge, some electrons flow into the grounding electrode plate to form an electric current after meeting the grounding electrode plate, and some electrons escape from the surface of the dielectric and meet indoor air molecules. When the escaping electrons reach a certain speed, oxygen molecules can be excited into an ionic state, ionizing the gas to charge the particulate matter. When the charged particulate matter encounters the grounding electrode or an object with the opposite polarity, it is very easy to reduce the particulate matter in the air, convert the floating dust in the air into settled dust, reduce the floating particulate matter, and at the same time, the generated non-equilibrium oxygen ions also have a physical impact with high kinetic energy. Under the dual action of physical and chemical effects, it is beneficial to the decomposition of harmful volatile gas molecules and can also play a role in killing germs and microorganisms, achieving the purpose of air purification and disinfection.

[0052] In the fan of the present invention, by arranging a bipolar ion generator in the main body, when the fan works, under the driving action of the motor, the airflow can carry and diffuse the positive and negative purification ions generated by the ion sheet to the entire indoor space, realizing a comprehensive and continuous purification effect in the entire indoor space, being able to effectively kill the floating bacteria in the indoor air, reduce the inhalable particulate matter in the air, decompose the TVOC in the air, eliminate odors, effectively improve the indoor air quality, and ensure the air supply quality of the fan. In addition, in the bipolar ion generator of the fan of the present invention, by electrically connecting the plug to the ion sheet in a pluggable manner, it is convenient for the installation, maintenance and replacement of the ion sheet. When the ion sheet fails, only need to unplug the plug and replace the ion sheet, without the need to replace the power converter and other circuit structures or electronic components in the fan.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered to be within the scope described in this specification.

[0054] The above-described embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but should not be construed as limiting the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
