[0002] Ion generators use high-voltage transformers to boost the voltage to the required voltage, thereby generating positive and negative ions that are released into the surrounding air, purifying the air and improving people's living environment. This type of device that artificially generates positive and negative ions is called an air purification ion generator, or ion generator for short.

DETAILED DESCRIPTION

[0028] 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.

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.

[0030] In one embodiment, Figure 1 and Figure 2 As shown, the bipolar ion generator includes an ion sheet 100 and a shell 200. The ion sheet 100 is a layered rectangle and is used to generate ion groups with opposite charges. The shell 200 includes an upper shell 210 and a lower shell 220, both of which are made of insulating materials and are arranged on the outside of the ion sheet 100 to fix the ion sheet 100 and prevent the layered ion sheet 100 from moving between layers. A hollow area 240 is opened on the shell 200 to release the ion group.

[0031] The structure of the ion plate 100 is as follows Figure 3 and Figure 4 As shown, from one side surface to the other side surface, the ion sheet 100 includes a first grounding plate 110, a first dielectric barrier plate 120, a first emitter plate 130, a second dielectric barrier plate 140, a second emitter plate 150, a third dielectric barrier plate 160, and a second grounding plate 170. The width dimensions of the first grounding plate 110 and the first emitter plate 130 are smaller than or equal to the first dielectric barrier plate 120. The width dimensions of the second grounding plate 170 and the second emitter plate 150 are smaller than or equal to the third dielectric barrier plate 160. The width dimensions of the first dielectric barrier plate 120 and the third dielectric barrier plate 160 are smaller than the second dielectric barrier plate 140, so as to form a step 230 on the side of the ion sheet 100. Figure 4 and Figure 5 As shown, when the shell 200 is encapsulated outside the ion sheet 100, the upper shell 210 and the lower shell 220 are clamped at the step 230 on the second dielectric blocking plate 140, so that the surface of the ion sheet 100 is no longer severely recessed in the hollow area 240 of the shell 200, and the release of the ion group is smoother.

[0032] In addition, Figure 5 In the embodiment shown, the surface of the ion sheet 100 is flush with the surface of the housing 200. It is understood that in other embodiments, the surface of the ion sheet 100 may also protrude from the surface of the housing 200, so that the release of the ion group is smoother. Figure 5 In the embodiment shown, the surface of the ion sheet 100 is flush with the surface of the housing 200. However, at both ends of the ion sheet 100, the housing 200 is still disposed outside the ion sheet 100. Therefore, the housing 200 can still fix the ion sheet 100 and prevent the layered ion sheet 100 from moving between layers. Figure 5 As shown, a plurality of stop bars 250 are spaced apart on the hollow area 240 of the housing 200 to fix the ion sheet 100 and further prevent the layered ion sheet 100 from moving between layers.

[0033] In addition, if Figure 1 and Figure 4As shown, the bipolar ion generator further comprises a first electrical connector 300 and a second electrical connector 400, the first emitter plate 130 and the second emitter plate 150 form a first lead-out end 180 at one end of the ion sheet 100, the first ground plate 110 and the second ground plate 170 form a second lead-out end 190 at the same end of the ion sheet 100, one end of the first electrical connector 300 is electrically connected with the first lead-out end 180, and the other end is connected with alternating high voltage, one end of the second electrical connector 400 is electrically connected with the second lead-out end 190, and the other end is connected with ground wire. In an embodiment, the first emitter plate 130 and the second emitter plate 150 are respectively connected with alternating high voltage, the range of the high voltage is 1000v-3000v, and when the bipolar ion generator works, another power converter is needed to convert the commercial power into the voltage required by the ion sheet 100.

[0034] In Figure 4 In the embodiment shown, the first emitter plate 130 and the first ground plate 110 form a first electric field, and electrons are led out from one end of the first emitter plate 130 to the first ground plate 110 through the intermediate first dielectric barrier plate 120, the second emitter plate 150 and the second ground plate 170 form a second electric field, and electrons are led out from one end of the second emitter plate 150 to the second ground plate 170 through the intermediate third dielectric barrier plate 160, the direction of the first electric field is opposite to that of the second electric field, and thus the bipolar ion generator with symmetrical structure generates ions alternately on both sides, increases the number of escaped electrons per unit time, enhances the ion airflow, and accelerates the speed of air purification.

[0035] It can be understood that in other embodiments, such as Figure 6As shown, the ion sheet 100 can further include only the first emitter plate 130, the first ground plate 110 and the first dielectric barrier plate 120 in sequence from one side surface to the other side surface, the first dielectric barrier plate 120 being located between the first emitter plate 130 and the first ground plate 110, the first emitter plate 130 and the first ground plate 110 forming a first electric field, and the electrons being led out from the first emitter plate 130 to the first ground plate 110 through the first dielectric barrier plate 120 in the middle. The first dielectric barrier plate 120 includes a first portion 121 and a second portion 122, the first portion 121 being close to the first ground plate 110, and the second portion 122 being close to the first emitter plate 130, the first ground plate 110 having a size in the width direction smaller than or equal to the first portion 121, the first emitter plate 130 having a size in the width direction smaller than or equal to the second portion 122, and the first portion 121 having a size in the width direction smaller than the second portion 122, so as to form a step 230 at the side edge of the ion sheet 100, so that the upper shell 210 and the lower shell 220 can be clamped at the step 230 of the first dielectric barrier plate 120, and further so that the ion leading-out surface of the ion sheet 100 is no longer severely recessed in the hollowed-out area 240 of the shell 200, and the release of the ion group is more smooth.

[0036] In addition, as shown in Figure 1 The one end of the first electric connector 300 is electrically connected with the emitter plate, and the other end is electrically connected with the first plug 500 in a plug-removable manner. The one end of the second electric connector 400 is electrically connected with the ground plate, and the other end is used for electrically connected with the second plug 600 in a plug-removable manner. The structure of the first electric connector 300, the first plug 500, the second electric connector 400 and the second plug 600 is shown in Figure 7 The first plug 500 is connected with the alternating high voltage through the first lead wire 530, and the second plug 600 is connected with the ground through the second lead wire 630. In a specific embodiment, the one end of the first electric connector 300 is welded with the first leading-out end 180 through high-frequency welding, so as to realize stable and firm electrical connection, and the other end is used for electrically connected with the first plug 500 in a plug-removable manner. The one end of the second electric connector 400 is welded with the second leading-out end 190 through high-frequency welding, so as to realize stable and firm electrical connection, and the other end is used for electrically connected with the second plug 600 in a plug-removable manner.

[0037] As shown in Figure 7 The first plug 500 includes a third electric connector 510, a first insulating member 520 and a first lead wire 530. The third electric connector 510 is located in the first insulating member 520. The one end of the third electric connector 510 protrudes from the first insulating member 520 to form a first protruding end 540. The other end of the third electric connector 510 is electrically connected with the first lead wire 530 in the first insulating member 520. Figure 7As shown, the second plug 600 includes a fourth electrical connector 610, a second insulating member 620, and a second conductive wire 630. The fourth electrical connector 610 is located within the second insulating member 620, and one end of the fourth electrical connector 610 protrudes from the second insulating member 620 to form a second protruding end 640. The other end of the fourth electrical connector 610 is electrically connected to the second conductive wire 630 within the second insulating member 620. In a specific embodiment, the first insulating member 520 and the second insulating member 620 are made of an insulating material such as rubber or silicone.

[0038] like Figure 7 As shown, the first electrical connector 300 has a first port 310 at one end connected to the first plug 500. When the first plug 500 is inserted into the first socket 230 of the housing 200, the first protruding end 540 can be inserted into the first port 310, thereby electrically connecting the first plug 500 to the first emitter plate 130 and the second emitter plate 150. The second electrical connector 400 has a second port 410 at one end connected to the second plug 600. When the second plug 600 is inserted into the second socket 240 of the housing 200, the second protruding end 640 can be inserted into the second port 410, thereby electrically connecting the second plug 600 to the first grounding plate 110 and the second grounding plate 170. The contact areas between the first protruding end 540 and the first port 310, and between the second protruding end 640 and the second port 410, are both large, ensuring safe and reliable electrical conductivity between the first and second plugs 500, 600, and the ion generator.

[0039] In addition, to prevent incorrect insertion, Figure 7 As shown, the first protruding end 540 is cylindrical or cylindrical, and the first port 310 is cylindrical; the second protruding end 640 and the second port 410 are both flat, so that the first plug 500 can only be inserted into the first socket 230, and the second plug 600 can only be inserted into the second socket 240. In order to further enhance the recognition of the first plug 500 and the second plug 600, the outer cross-section of the first insulating member 520 is circular, and the outer cross-section of the second insulating member 620 is nearly elliptical or square. In addition, as shown in FIG. Figure 8 As shown, a first spring piece 320 is provided on the side wall of the first port 310. One end of the first spring piece 320 is connected to the side wall of the first port 310, and the other end is inclined or bent toward the inside of the first port 310. When the first protruding end 540 is inserted into the first port 310, the first spring piece 320 can press the first protruding end 540, so that the first protruding end 540 can be tightly contacted with the first electrical connector 300 to achieve a stable electrical connection. Similarly, as Figure 9As shown, a second spring clip 420 is provided on the side wall of the second port 410, one end of the second spring clip 420 is connected to the side wall of the second port 410, and the other end is inclined or bent toward the interior of the second port 410. When the second protruding end 640 is inserted into the second port 410, the second spring clip 420 can press the second protruding end 640, so that the second protruding end 640 can be in close contact with the second electrical connector 400 to achieve a stable electrical connection.

[0040] In addition, to facilitate processing, the first electrical connector 300 and the second electrical connector 400 are both made of a metal material with good conductivity. The first spring piece 320 is integrally formed with the first electrical connector 300, and the second spring piece 420 is integrally formed with the second electrical connector 400. Furthermore, it is understood that in other embodiments, the end of the first electrical connector 300 connected to the first plug 500 may be provided with another elastic structure, collectively referred to as a first elastic member, which can press against the first plug 500 so that the first plug 500 can tightly contact the first electrical connector 300 to achieve a stable electrical connection; and the end of the second electrical connector 400 connected to the second plug 600 may be provided with another elastic structure, collectively referred to as a second elastic member, which can press against the second plug 600 so that the second plug 600 can tightly contact the second electrical connector 400 to achieve a stable electrical connection.

[0041] Additionally, in one embodiment, Figure 7 As shown, the end of the first electrical connector 300 electrically connected to the first lead-out terminal 180 of the emitter plate is a square hollow structure, and a first support member 340 is built in. The first support member 340 is used to make the first electrical connector 300 tightly contact the first lead-out terminal 180 to achieve a stable electrical connection; the end of the second electrical connector 400 electrically connected to the second lead-out terminal 190 of the grounding plate is also a square hollow structure, and a second support member 440 is built in. The second support member 440 is used to make the second electrical connector 400 tightly contact the second lead-out terminal 190 to achieve a stable electrical connection. In one embodiment, the first electrical connector 300 is fixedly connected to the first lead-out terminal 180 of the emitter plate by welding, and the second electrical connector 400 is fixedly connected to the second lead-out terminal 190 of the emitter plate by welding. The first support member 340 and the second support member 440 both play a supporting role to prevent the first electrical connector 300, the first lead-out terminal 180, the second electrical connector 400 or the second lead-out terminal 190 from structural deformation, thereby preventing poor electrical connection.

[0042] In one embodiment, the present invention further provides an air purification device, comprising the bipolar ion generator of any one of the above embodiments.

[0043] The bipolar ion generator 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 to generate gas ions of opposite signs. A part of the electrons meet the grounding plate and flow into the grounding plate to form current, 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 rate, they can stimulate oxygen molecules to be ionic, ionize the gas and charge the particles. If the charged particles encounter the grounding electrode or the object of opposite polarity, 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-balanced positive and negative oxygen ions generated have a physical impact with high kinetic energy, which is beneficial to the decomposition of harmful volatile gas molecules under the dual action of physical and chemical effects, and can also disinfect pathogenic microorganisms, thereby achieving the purpose of air purification and disinfection.

[0044] The bipolar ion generator and air purification device of the present invention reasonably arrange the internal structure of the ion plate so that the size of the ion plate near the surface in the width direction is smaller than the size near the middle of the interior, so that a step is formed on the side of the ion plate. The shell can be clamped at the step, so that the surface of the ion plate is no longer seriously recessed in the hollow area of ​​the shell, and the release of the ion group is smoother.

[0045] 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.

[0046] 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.
