Description

Technical Field

[0001] The present invention relates to the field of fans, and particularly to a bladeless fan with a purification function. Background Art

[0002] A bladeless fan, also called an air multiplier, can generate natural and continuous cool air. Compared with ordinary fans, it is safer, more fashionable, and generates more stable and high-speed airflows. The bladeless fan sucks in air through the body, then guides the air into a ring, and sprays it out from the slit of the ring, driving the surrounding air to generate wind power. The bladeless fan can suck in the surrounding air and then spray it out through a narrow slit to generate comfortable natural wind. The bladeless fan not only has higher energy efficiency but is also extremely easy to clean. Since it has no fan blades, it is safer to use. However, the existing bladeless fans have relatively single functions and need further improvement. Summary of the Invention

Detailed implementation mode

[0036] For the convenience of understanding 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, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0037] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there can also be a central 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 a central 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.

[0038] In one embodiment, as Figure 1 and Figure 2As shown in the figure, the bladeless fan of the present invention includes a fan body 100, a bipolar ion generator 200, and a bracket 300. Among them, the fan body 100 includes a first housing 110 and a blower 120 disposed inside the first housing 110. An air inlet 112 and a first air outlet 113 are provided on the first housing 110. The first air outlet 113 is an elongated slit air outlet, which is arranged in an inverted U shape around the upper half of the first housing 110. The lower half of the first housing 110 includes a panel 111. The first air outlet 113 is provided on the side of the first housing 110 opposite to the panel 111. The blower 120 includes a second air outlet 121. As Figure 3 shown, the first air outlet 113 is in communication with the second air outlet 121 of the blower.

[0039] As Figures 4 to 6 shown, the bipolar ion generator 200 includes an ion sheet 210, a first plug 220, a second plug 230, and a power converter 240. The ion sheet 210 is electrically connected to the power converter 240 through the first plug 220 and the second plug 230. As Figure 4 shown, the power converter 240 is installed near the ion sheet 210 on the top wall 122 of the blower 120. The power converter 240 is used to convert mains power into the power required by the ion sheet 210. The bracket 300 is used to install the ion sheet 210 at the second air outlet 121 of the blower 120. As Figure 2 shown, when the bladeless fan is working, under the action of the blower 120, air flows in from the air inlet 112, and the bipolar ion generator 200 releases a group of ions with opposite charges. When the air flow passes through the bipolar ion generator 200, the group of ions is carried out of the fan body 100 from the first air outlet 113, thereby purifying the indoor air.

[0040] In one embodiment, as Figure 7As shown, 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 220. The first plug 220 is connected to an AC high voltage through a power converter 240. In one embodiment, the range of the high voltage is 1000V - 3000V. 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 230. The second plug 230 is grounded through the power converter 240. 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 speed.

[0041] 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. 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.

[0042] As Figures 4 to 6 shown, the ion sheet 210 further includes a second housing 250 made of an insulating material. The second housing 250 is disposed outside the ion sheet 210. Hollow areas 400 are provided on both sides of the ion sheet 210 on the second housing 250 to facilitate the outflow of the heteroionic groups with positive and negative charges. The ion sheet 210 is installed at the second air outlet 121 of the fan 120 through two brackets 300. As Figure 5As shown, the bracket 300 includes a fixed connection of a fixed plate 310 and a mounting plate 320. The fixed plate 310 is used to be fixedly connected to the side wall 123 of the second air outlet 121 of the fan 120 through fasteners. Two brackets 300 are mounted on the opposite side walls 123 of the second air outlet 121 of the fan 120 through the fixed plates 310. At the ends of the mounting plates 320 of the two brackets 300 close to each other, a first mounting groove (not shown in the figure) and a second mounting groove 321 are respectively provided. Opposite to each other on the second housing 250 of the ion sheet 210, a first connection end 251 and a second connection end 252 are provided. The first connection end 251 can be inserted into the first mounting groove, and the second connection end 252 can be inserted into the second mounting groove 321, so that the ion generator is mounted at the second air outlet 121 of the fan 120 through the two brackets 300. In addition, as Figure 5 shown, both the first connection end 251 and the second connection end 252 are stepped. The dimension of the end close to the bracket 300 is smaller than the dimension of the end far from the bracket 300. The smaller end of the first connection end 251 can be inserted into the first mounting groove, and the smaller end of the second connection end 252 can be inserted into the second mounting groove 321.

[0043] In Figures 5 to 7 the shown 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, at the ends of the two brackets 300 far from the ion sheet 210, a first lead wire opening 330 and a second lead wire opening (not shown in the figure) are respectively provided. The first lead wire opening 330 is communicated with the first mounting groove, and the second lead wire opening is communicated with the second mounting groove 321. As Figure 8As shown, a first through hole 124 and a second through hole (not shown in the figure) are correspondingly formed on the opposite side walls 123 of the second air outlet 121; the first plug 220 is detachably electrically connected to the emission electrode plate of the ion sheet 210 through the first through hole 124 and the first lead port 330, and the second plug 230 is detachably electrically connected to the grounding electrode plate of the ion sheet 210 through the second through hole and the second lead port. It can be understood that in other embodiments, the first lead end 218 and the second lead end 219 can be located at the same end of the ion sheet 210 close to the first installation groove. At this time, only a first lead port 330 needs to be formed at one end of the bracket 300 away from the ion sheet 210, and a first through hole 124 is formed at a position on the side wall 123 of the second air outlet 121 corresponding to the first lead port 330. The first lead port 330 is communicated with the first installation groove. The first plug 220 can be detachably electrically connected to the emission electrode plate of the ion sheet 210 through the first through hole 124 and the first lead port 330, and the second plug 230 can be detachably electrically connected to the grounding electrode plate of the ion sheet 210 through the first through hole 124 and the first lead port 330. When the first lead end 218 and the second lead end 219 are located at the same end of the ion sheet 210, the structure after the first plug 220 and the second plug 230 are connected to the ion sheet 210 is as Figure 9 shown. With such a design, the power converter 240 only needs to be arranged at a position close to the first lead port 330, avoiding wire winding when the second plug 230 is connected to the power converter 240.

[0044] In one embodiment, as Figure 10 and Figure 11 shown, the ion sheet 210 further includes a first electrical connector 260 and a second electrical connector 270. The first plug 220 is detachably electrically connected to the emission electrode plate of the ion sheet 210 through the first electrical connector 260, and the second plug 230 is detachably electrically connected to the grounding electrode plate of the ion sheet 210 through the second electrical connector 270. One end of the first electrical connector 260 is electrically connected to the first lead end 218, and the other end is detachably electrically connected to one end of the first plug 220. The other end of the first plug 220 is connected to an AC high voltage through the power converter 240; one end of the second electrical connector 270 is electrically connected to the second lead end 219, and the other end is detachably electrically connected to one end of the second plug 230. The other end of the second plug 230 is connected to the ground wire through the power converter 240. In a specific embodiment, one end of the first electrical connector 260 is welded to the first lead end 218 by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used for detachably electrical connection with the first plug 220; one end of the second electrical connector 270 is welded to the second lead end 219 by high-frequency welding to achieve a stable and firm electrical connection, and the other end is used for detachably electrical connection with the second plug 230.

[0045] AsFigure 10 As shown, the first plug 220 includes a third electrical connector 221, a first insulating member 222, and a first wire 223. The third electrical connector 221 is located within the first insulating member 222. One end of the third electrical connector 221 protrudes from the first insulating member 222 to form a first protruding end 224. The other end of the third electrical connector 221 is electrically connected to the first wire 223 within the first insulating member 222. As shown in Figure 11, the second plug 230 includes a fourth electrical connector 231, a second insulating member 232, and a second wire 233. The fourth electrical connector 231 is located within the second insulating member 232. One end of the fourth electrical connector 231 protrudes from the second insulating member 232 to form a second protruding end 234. The other end of the fourth electrical connector 231 is electrically connected to the second wire 233 within the second insulating member 232. The first protruding end 224 can be inserted into the first electrical connector 260, such that the first plug 220 can be electrically connected to the first emitting electrode plate 213 and the second emitting electrode plate 215; the second protruding end 234 can be inserted into the second electrical connector 270, such that the second plug 230 can be electrically connected to the first grounding electrode plate 211 and the second grounding electrode plate 217.

[0046] In addition, as shown in the figure, a first elastic piece 261 is provided on the side wall 123 of the first electrical connector 260. The first elastic piece 261 is inclined or bent towards the interior of the first electrical connector 260. After the first protruding end 224 is inserted into the first electrical connector 260, the first elastic piece 261 can press against the first protruding end 224, such that the first protruding end 224 can be in close contact with the first electrical connector 260 to achieve a stable electrical connection. Similarly, as shown in the figure, a second elastic piece 271 is provided on the side wall 123 of the second electrical connector 270. The second elastic piece 271 is inclined or bent towards the interior of the second electrical connector 270. After the second protruding end 234 is inserted into the second electrical connector 270, the second elastic piece 271 can press against the second protruding end 234, such that the second protruding end 234 can be in close contact with the second electrical connector 270 to achieve a stable electrical connection.

[0047] In addition, for the convenience of processing, both the first electrical connector 260 and the second electrical connector 270 are made of a metal material with good electrical conductivity. The first elastic piece 261 is integrally formed with the first electrical connector 260, and the second elastic piece 271 is integrally formed with the second electrical connector 270. Additionally, it can be understood that in other embodiments, other elastic structures may be provided at the end of the first electrical connector 260 connected to the first plug 220, collectively referred to as the first elastic member. The first elastic member can press against the first plug 220, enabling the first plug 220 to be in close contact with the first electrical connector 260 to achieve a stable electrical connection; other elastic structures may be provided at the end of the second electrical connector 270 connected to the second plug 230, collectively referred to as the second elastic member. The second elastic member can press against the second plug 230, enabling the second plug 230 to be in close contact with the second electrical connector 270 to achieve a stable electrical connection.

[0048] In Figures 10 to 13 In the illustrated embodiment, the first plug 220 is electrically connected to the first electrical connector 260 in a pluggable manner, and the second plug 230 is electrically connected to the second electrical connector 270 in a pluggable manner. Such a design facilitates the installation, maintenance, and replacement of the ion sheet 210. Additionally, in some embodiments, one end of the first plug 220 is electrically connected to the first electrical connector 260 in a pluggable manner, and the other end is also electrically connected to the power converter 240 in a pluggable manner. One end of the second plug 230 is electrically connected to the second electrical connector 270 in a pluggable manner, and the other end is also electrically connected to the power converter 240 in a pluggable manner. Such a design facilitates the selection or replacement of plug wires of different lengths or specifications according to the specific installation positions of the ion sheet 210 and the power converter 240. When installing the ion sheet 210 and the power converter 240 at the second air outlet 121 of the fan 120, only the appropriate installation positions of the ion sheet 210 and the power converter 240 need to be considered. After the ion sheet 210 and the power converter 240 are installed, the first plug 220 and the second plug 230 of the appropriate length or specification are then pluggably connected between the ion sheet 210 and the power converter 240.

[0049] In addition, 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 bladeless fan. In another embodiment, a pneumatic relay for detecting wind force can be installed in the air passage of the bladeless fan or the air flow passage of the fan 120. When air flow is detected, the pneumatic relay controls the ion sheet 210 to generate ions, thereby achieving automatic control and avoiding the ineffective operation of the bipolar ion generator 200 to save 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 bladeless fan, there is no need to install a pneumatic relay.

[0050] In addition, in one embodiment, as Figures 14 to 16 shown, the ion sheet includes a second housing 250 made of an insulating material. The second housing 250 includes an upper housing 253 and a lower housing 254. The second housing 250 is disposed outside the ion sheet 210. Hollow areas 400 are provided on both the upper and lower sides of the ion sheet 210 on the upper housing 253 and the lower housing 254 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 housing 253 and the lower housing 254 are clamped on the steps on both the upper and lower sides of the third dielectric barrier plate, so that the surface of the second housing 250 is flush with the surface of the ion sheet 210, which is more convenient for the positive and negative ion groups with opposite charges to flow out from the hollow areas.

[0051] In the bipolar ion generator of the bladeless 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. An alternating current is used. On the grounded side of the electric field, electrons emitted from the emission electrode plate are led out of the dielectric barrier plate to generate ionized gas ions with opposite charges. A part of the electrons flow into the grounding electrode plate to form an electric current after meeting the grounding electrode plate, and another part of the 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 to 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. At the same time, the generated non-equilibrium oxygen ions also have a physical impact effect with high kinetic energy. Under the dual action of the 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] The bladeless fan of the present invention is provided with a bipolar ion generator at the position of the second air outlet of the fan. When the bladeless fan is operating, the airflow can carry and diffuse the positive and negative purification ions generated by the ion sheet to the entire indoor space, achieving a comprehensive and continuous purification effect in the entire area. By integrating the bladeless fan and the air purifier, it can effectively kill floating bacteria in the air, reduce inhalable particulate matter in the air, decompose TVOC in the air, eliminate odors, and ensure the safety of the air supply of the bladeless fan. In addition, for the bipolar ion generator in the bladeless fan of the present invention, the plug is electrically connected to the ion sheet in a pluggable manner, which facilitates the installation, maintenance, and replacement of the ion sheet. When the ion sheet fails, only the plug needs to be unplugged and the ion sheet needs to be replaced, without the need to replace the power converter and other circuit structures or electronic components in the bladeless fan.
