An ionic wind assembly 100 according to an embodiment of the present invention is described below with reference to fig. 1-25.

An ion wind assembly 100 according to an embodiment of the present invention may include: a discharge electrode 1 and a receiving electrode 2.

As shown in fig. 1 to 24, the ion wind module 100 according to the embodiment of the present invention is suitable for being applied to an air conditioner, so as to utilize charged particles to drive air to flow, thereby generating a proper amount of wind to provide indoor cooling or air circulation services.

Because the ion wind subassembly in traditional air conditioner adopts corona discharge principle to produce ion wind mostly, namely the discharge electrode adopts the structure of needle or line to make discharge electrode and receiving electrode arrange with certain structural style, under high voltage power supply's effect, form ion wind, realize the windless wheel air supply, but the line discharge electrode need exert certain pulling force at the both ends of line in order to fix a position, easily take place to stretch out in long-term high pressure use, the needle discharge electrode need be inserted the needle on fixed conductive structure, consequently the technology is complicated, the processing degree of difficulty is very big, be unfavorable for large-scale production.

For this reason, the embodiment of the present invention designs an ion wind assembly 100 having a discharge electrode 1 with a saw-tooth structure. The sawtooth structure is easier to process and can be produced in a large scale, so that the large scale production of the ion wind component 100 is realized, and the quality of the sawtooth structure is more stable and reliable, so that the reliability and the safety of the ion wind component 100 are higher.

Wherein the discharge electrode 1 includes an electrode tab 11, the electrode tab 11 is adapted to be energized to generate charged particles so that the charged particles can move to the receiving electrode 2 to generate an ion wind, further, the electrode tab 11 includes a body portion 111 and a serrated portion 112 (refer to fig. 21 and 22), wherein the body portion 111 is adapted to be connected to the receiving electrode 2 to fixedly connect the entire electrode tab 11 to the receiving electrode 2, thereby ensuring the overall stability of the ion wind module 100, and the serrated portion 112 is connected to one side of the width of the body portion 111 so that the serrated portion 112 can be disposed toward the receiving electrode 2, wherein the serrated portion 112 includes a plurality of serrations arranged along the length direction of the body portion 111, each serration including two serrated oblique sides arranged along the length direction of the body portion 111, the two serrated oblique sides being close to each other in a direction away from the body portion 111 to meet to form serrated tips of the serrations, each serrated side being a discharge point, thereby effectively increasing a discharge point, so as to improve ionization efficiency and an ion generation amount, thereby increasing an air volume.

Specifically, the whole electrode plate 11 can be manufactured by a stamping process, so that the overall strength of the electrode plate 11 can be ensured, and the electrode plate is more convenient to manufacture, namely, the saw teeth are formed by stamping the metal plate, and the body part 111 can be fixed, so that the arrangement stability of the electrode plate can be ensured without applying a pulling force to the saw teeth part 112, the risk of snapping is not easy to occur, and an independent conductive structure is not required to be connected and fixed. Therefore, the manufacturing and processing technology is simpler, the processing difficulty is lower, and the large-scale production of the ion wind component 100 can be facilitated.

Further, the receiving electrode 2 is suitable for receiving the charged particles generated by the electrode plate 11, and the receiving electrode 2 is spaced apart from the discharge electrode 1, so that the charged particles can drive air to flow in the process of moving from the electrode plate 11 to the receiving electrode 2, and wind is generated.

Still further, the receiving electrode 2 is located at a side of the serration part 112 away from the body part 111, i.e. the serration part 112 is located close to the receiving electrode 2, in order to generate the ion wind, wherein the ion wind assembly 100 is adapted to be powered on to form the ion wind by corona discharge of the tooth tip. That is, the ion wind assembly 100 is adapted to be electrically connected to generate charged particles by corona discharge at the discharge electrode 1 and to form an ion wind by migration of the charged particles toward the receiving electrode 2. That is, the electrode sheet 11 and the receiving electrode 2 are respectively electrically connected to the power source 4 so as to drive the discharge electrode 1 to generate charged particles through corona discharge, and an electric field is formed between the discharge electrode 1 and the receiving electrode 2 to cause the charged particles to migrate toward the receiving electrode 2 to form an ion wind.

And, the receiving electrode 2 can also be used as a dust collecting electrode to adsorb particulate matters in the air, so as to realize the function of purifying the air.

According to the ion wind component 100 of the embodiment of the invention, the saw-tooth structure is adopted as the discharge electrode 1 in the ion wind component 100, so that the ion wind component 100 is easier to process and can be produced in a large scale, and the mass production of the ion wind component 100 is realized, and the whole structure of the saw-tooth structure is more stable and reliable, so that the reliability and the safety of the ion wind component 100 are higher.

With reference to the embodiments shown in figures 2, 9 and 16, each tooth tip of the electrode sheet 11 is disposed at equal spacing from the receiver electrode 2. In other words, the distance between each discharge point and the receiving electrode 2 is equal, so that the particle movement distances between the discharge electrode 1 and the receiving electrode 2 are equal, uniform discharge is ensured, and the stability of airflow flow is ensured to avoid the phenomenon of turbulent flow.

As shown in fig. 3, 10 and 16, the distance L between each tooth tip of the electrode sheet 11 and the receiving electrode 2 ranges from 5mm to 30mm, or from 5mm to 20mm, or from 10mm to 15mm. Namely, the distance between the electrode sheet 11 and the receiving electrode 2 is controlled to be between 5mm and 30mm, or between 5mm and 20mm, or between 10mm and 15mm. That is, L ranges from 5mm to 30mm, preferably from 5mm to 20mm, and more preferably from 10mm to 15mm. Therefore, the air quantity of the whole system can be adjusted more conveniently while ensuring the generation quantity of the ion wind.

Referring to fig. 25, the ignition voltage in the figure is a voltage when the ion wind module 100 starts to generate current, the ignition voltage is a voltage when the voltage between two electrodes of the ion wind module 100 is too high, an ignition phenomenon occurs, which affects normal operation of the ion wind module 100, the voltage when the ignition phenomenon occurs is the ignition voltage, and the voltage window = the ignition voltage-the ignition voltage, which is a normal operating voltage of the ion wind module 100 and is also an adjustable voltage range of the ion wind module 100, wherein L is a factor determining the voltage window, and the value of L is adjusted, so that the thickness and the voltage window of the ion wind module 100 can be changed, and the total air output of the ion wind can also be affected.

Moreover, when the ion wind module 100 is optimized, the above parameters need to be adjusted simultaneously to obtain the best wind outlet effect. That is, after the parameters (curvature, material, etc.) of the electrode itself are determined, the parameter adjustment of the ion wind module 100 is mainly to adjust the above parameters.

The voltage section to be selected as the operating voltage of the ion wind module 100 is determined according to actual needs, for example, a scene requiring a smaller ion wind volume may be selected as the ion wind module 100 operating at a low voltage (less than 6 kV), which has the advantages of higher safety, better electromagnetic compatibility, fewer byproducts, but a narrow operating window and needs to be matched with a finely adjustable circuit. When strong air supply is needed, the high-voltage (greater than 20 kV) ion wind assembly 100 is selected, the wind speed and the wind volume of the generated ion wind are higher than those of the ion wind in the low-voltage state, but the problems of safety regulations, electromagnetic compatibility, byproducts and the like need to be considered, and a safe feedback signal acquisition circuit needs to be equipped.

In conjunction with the embodiments shown in fig. 5-7, 12-14, and 18-20, the discharge electrode 1 includes a plurality of electrode pieces 11, and the electrode pieces 11 can discharge simultaneously to increase the air volume, wherein the electrode pieces 11 are spaced apart and arranged in parallel along the thickness direction of the electrode pieces 11. Therefore, the ion wind module 100 can ensure the maximum ion wind amount and avoid the mutual interference between the electrodes at the same time, so that the ion wind module 100 can operate more stably.

According to some embodiments of the present invention, the discharge electrode 1 includes n electrode sheets 11, the plurality of tooth tips of two adjacent electrode sheets 11 are staggered along the length direction of the main body 111, any tooth tip on any electrode sheet 11 is adjacent to a tooth tip on an adjacent electrode sheet 11, a distance m1 in the length direction of the main body 111 satisfies m1= m2/n, and a value of m2 is in a range of 1mm to 10mm, or 1mm to 5mm, or 1mm to 3mm. For example, the discharge electrode 1 includes two electrode sheets 11, a first electrode sheet and a second electrode sheet. The plurality of tooth tips on the first electrode plate and the plurality of tooth tips on the second electrode plate are staggered along the length direction of the first electrode plate, namely, the area between two adjacent tooth tips on the first electrode plate is opposite to one tooth tip on the second electrode plate along the thickness direction of the first electrode plate. One tooth tip on the first electrode plate is a first tooth tip, one tooth tip on the second electrode plate is a second tooth tip, the second tooth tip is closest to the first tooth tip along the length direction of the first electrode plate, and the distance between the first tooth tip and the second tooth tip along the length direction of the first electrode plate is m1. That is, m2 ranges from 1mm to 10mm, preferably from 1mm to 5mm, and more preferably from 1mm to 3mm. Therefore, the discharge efficiency can be further ensured, the sawtooth pitch of the discharge electrode 1 can be ensured to be in the best processing condition according to the parameters, and the electrode plates 11 can be formed by overlapping and combining, namely, the electrode plates can be fixed by screws, rivets or welding, so that the electrode plates are easy to process.

As a preferred embodiment, the electrode plates 11 are connected by an adjusting mechanism (not shown in the drawings) so that the distance between two adjacent electrode plates 11 can be adjusted, and thus the air output can be changed by adjusting the distance between two adjacent electrode plates 11, so as to facilitate the adjustment of the air output.

Referring to fig. 18, the number of the electrode sheets 11 is at least three, and the distance between every two adjacent electrode sheets 11 is equal, so that the air flow formed between each electrode sheet 11 and the receiving electrode 2 can flow stably in parallel, and the phenomenon of turbulent flow is avoided; and/or the distance A between two adjacent electrode plates 11 ranges from 5mm to 100mm, or from 10mm to 80mm, or from 20mm to 50mm. Namely, the distance between two adjacent electrode plates 11 is controlled between 5mm and 100mm, or between 10mm and 80mm, or between 20mm and 50mm. That is, A is in the range of 5mm to 100mm, preferably in the range of 10mm to 80mm, and more preferably in the range of 20mm to 50mm. Therefore, the ion wind module 100 can ensure the maximum ion wind amount and avoid the mutual interference between the electrodes at the same time, so that the ion wind module 100 can operate more stably.

As shown in fig. 1-3, the ion wind assembly 100 further includes: the mounting bracket 3, a plurality of electrode pads 11 are all installed to the mounting bracket 3, and the mounting bracket 3 includes the conducting part that is connected with each electrode pad 11 electricity, and the conducting part is suitable for the electricity to connect so that a plurality of electrode pads 11 electricity.

The ion wind module 100 further includes a mounting bracket 3, and two ends of the length of the main body 111 are respectively mounted on the mounting bracket 3. That is to say, the both ends of electrode slice 11 are connected with installing support 3 respectively to guarantee electrode slice 11's stability of setting, thereby guarantee the air-out that ion wind subassembly 100 can be stable.

Further, the receiver electrode 2 is also mounted to the mounting bracket 3. That is, the electrode plates 11 are connected to the receiving electrode 2 through the same mounting bracket 3 to ensure a stable conductive connection therebetween, and the electrode plates 11 are adapted to be electrically connected to the power source 4 through the conductive portion, so that the power source 4 can simultaneously supply power to the electrode plates 11, so that the electrode plates 11 can simultaneously generate charged particles to increase the air volume of the ion wind module 100.
