Description

Technical Field

[0001] This invention relates to the field of ion generating devices, and more specifically, to a wind-driven cleaning device for cleaning carbon fiber brushes of ion generating devices and an air conditioning system having the same. Background Technology

[0002] An ion generator typically includes a positive plate and a negative plate, on which carbon fiber brushes are mounted. When energized, these brushes produce negatively charged ions, which adsorb dust and other particles in the air, causing them to accumulate and fall off, thus purifying the air. However, due to electrostatic effects, dust often accumulates on the carbon fiber brushes, which affects their operation and reduces their efficiency.

[0003] The ion generator can be installed in the fan coil unit of an air conditioning system, in which case it will be difficult to clean the carbon fiber brushes inside. Summary of the Invention

[0004] The purpose of this invention is to solve or alleviate the problems existing in the prior art.

[0005] On one hand, a wind-driven cleaning device for an ion generator apparatus is provided, comprising: Blades that can pivot along a pivot axis; The transmission mechanism connected to the pivot shaft; and The cleaning component is connected to the transmission mechanism. The blades are positioned in the airflow path, so that in the absence of wind, the blades are in a free state, and in the presence of wind, the blades pivot under the drive of the wind and drive the cleaning component to move through the transmission mechanism to scrape the carbon fiber brush on the electrode plate of the ion generator device.

[0006] Optionally, in the wind-driven cleaning device, the transmission mechanism converts the pivoting motion of the blades into the linear motion of the cleaning element.

[0007] Optionally, in the wind-driven cleaning device, the cleaning component includes a support shaft and cleaning arms extending axially from both sides of the support shaft.

[0008] Optionally, in the wind-driven cleaning device, the transmission mechanism drives the axis of the support shaft of the cleaning component to move linearly, so that the end of the cleaning arm scrapes the carbon fiber brush when it passes the carbon fiber brush.

[0009] Optionally, in the wind-driven cleaning device, the transmission mechanism is configured such that the movement distance of the cleaning element on the shaft corresponds to the pivot angle of the blade.

[0010] Optionally, in the wind-driven cleaning device, the transmission mechanism includes a first gear connected to the pivot shaft, a second gear meshing with the first gear, and a lead screw connected to the second gear, with a nut sleeved on the lead screw at one end of the cleaning component.

[0011] Optionally, in the wind-driven cleaning device, the axis of the support shaft is parallel to the pivot axis of the blade.

[0012] On the other hand, an ion generating apparatus is provided, comprising: Electrode plate, wherein a carbon fiber brush is disposed on the electrode plate; and According to various embodiments, the wind-driven cleaning device has blades that pivot under wind power and drive the cleaning component to move via the transmission mechanism to scrape the carbon fiber brush on the electrode plate of the ion generator device.

[0013] On the other hand, an air conditioning system is provided in which an ion generating device according to various embodiments is provided in the fan coil unit of the air conditioning system.

[0014] Optionally, when the fan of the fan coil unit starts or stops, the cleaning component scrapes the carbon fiber brush on the electrode plate of the ion generator device once.

[0015] The device according to an embodiment of the present invention can prevent dust accumulation on the carbon fiber brush of the ion generator. Attached Figure Description

[0016] The disclosure of this invention will become more readily understood with reference to the accompanying drawings. It will be readily understood by those skilled in the art that these drawings are for illustrative purposes only and are not intended to limit the scope of protection of this invention. Furthermore, similar numbers in the drawings are used to denote similar components, wherein: Figure 1 A schematic diagram of an ion generator according to an embodiment of the present invention in a windless state is shown; Figure 2 A schematic diagram of an ion generating device according to an embodiment of the present invention in a windy condition is shown; and Figure 3 A perspective view of an exemplary embodiment of the transmission mechanism is shown. Detailed Implementation

[0017] Several embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the directional terms such as up, down, left, right, front, back, inner, outer, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0018] refer to Figure 1 and Figure 2 An ion generating device according to an embodiment of the present invention will be described. The ion generating device may include a single substrate 4 or a pair of opposing electrode plates 4 (only one electrode plate 4 is shown in the figure). Each electrode plate 4 may include an electrode plate body 40 and carbon fiber brushes 41 disposed at corresponding positions on the substrate body 40. During operation, high voltage is applied to the carbon fiber brushes 41 of the electrode plate 4, thereby generating ions. In the illustrated embodiment, the electrode plate body 40 includes a first crossbeam 401 and a second crossbeam 402 arranged in parallel, and a plurality of longitudinal beams connecting the first crossbeam 401 and the second crossbeam 402. The carbon fiber brushes 41 are arranged at intervals on the first crossbeam 401 and the second crossbeam 402, and their positions correspond. The ion generating device according to this embodiment can be arranged in a fan coil unit of a central air conditioning system, thereby introducing, for example, negative ions into the indoor air. It should be understood that the electrode plates of the ion generating device shown in the figure are merely exemplary, and other suitable electrode plate structures may be selected.

[0019] During operation, dust in the air easily accumulates on the electrostatically charged carbon fiber brush 41, which affects the normal operation of the carbon fiber brush 41 and the ion generator. An air-driven cleaning device is also provided in the ion generator according to an embodiment of the present invention. The air-driven cleaning device includes: a blade 11 pivotable along a pivot shaft 10; a transmission mechanism 2 tractively connected to the pivot shaft 10; and a cleaning component 3 tractively connected to the transmission mechanism 2; the blade 11 is disposed in the air duct, for example, in a fan coil unit of a central air conditioning system, such that in the absence of airflow, the blade 11 is in a... Figure 1 In the free state shown, and in a windy condition, the blade 11 pivots under wind power and drives the cleaning element 3 to move via the transmission mechanism 2, thereby scraping the carbon fiber brush 41 on the electrode plate of the ion generator device. With this arrangement, each start-up or stop of the fan in the fan coil unit causes the cleaning element 3 to move, thus scraping the carbon fiber brush 41 once and removing the dust accumulated on it. The concept of the wind-driven cleaning device according to an embodiment of the invention utilizes the wind power from the air conditioning system as a power source to clean the dust accumulated on the carbon fiber brush, thereby ensuring the normal operation of the carbon fiber brush. This cleaning device has a simple structure, is easy to use, and requires no additional maintenance.

[0020] In some embodiments, the transmission mechanism 2 converts the pivoting motion of the blade 11 into linear motion of the cleaning element 3. For example, in the illustrated embodiment, the blade 11 is a single blade, and its two ends of the pivot axis 10 are pivotally connected to the first support 201 and the second support 202, respectively. Furthermore, the transmission mechanism 2 is located at the first support 201, and the left end of the pivot axis 10 of the blade 11 is also driveably connected to the transmission mechanism 2. The transmission mechanism 2 converts the pivoting motion of the pivot axis 10 of the blade 11 into linear motion of the cleaning element 3 along the D direction. In some embodiments, the transmission mechanism 2 may also be configured to convert the pivoting motion of the pivot axis 10 of the blade 11 into rotational motion of the cleaning element 3. In this case, the cleaning element 3 scrapes the individual carbon fiber brushes on the electrode plate during rotation.

[0021] In some embodiments, the cleaning component 3 includes a support shaft 31 and cleaning arms 32, 33 extending to both sides from the support shaft 31. The support shaft 31 is substantially parallel to and located between the first crossbeam 401 and the second crossbeam 402 of the electrode plate. The cleaning arms 32, 33 extend substantially perpendicularly to the support shaft 31 from the same position on the support shaft 31 to the positions of the first crossbeam 401 and the second crossbeam 402, respectively, ensuring that during the stroke of the cleaning component 3, the cleaning arms 32, 33 pass over and scrape the carbon fiber brushes 41 on the first crossbeam 401 and the second crossbeam 402. In some embodiments, the linear movement direction D of the cleaning component 3 is the axis of the support shaft 31. In some embodiments, the pivot shaft 10 of the blade 11 and the support shaft 31 of the cleaning component 3 are parallel and both are horizontal. During the linear movement of the cleaning component 3 along the D direction, the ends of the cleaning arms 32, 33 of the support shaft 31 scrape the carbon fiber brushes 41 as they pass over the corresponding carbon fiber brushes 41. The two ends of the cleaning component 3 are slidably connected to the first bracket 201 and the second bracket 202, respectively. For example, the right end of the cleaning component 3 is sleeved on the guide post 23 of the second bracket 202, while the left end of the cleaning component 3 is sleeved on the guide post 22 and the drive post 21 of the first bracket 201. It should be understood that, in alternative embodiments, cleaning components with different structures can be designed according to the specific arrangement of the electrode plates and carbon fiber brushes.

[0022] like Figure 3 As shown, in some embodiments, the transmission mechanism is configured such that the axial movement distance of the cleaning element corresponds to the pivot angle of the blade. In this case, the cleaning element 3 moves from... Figure 1 The windless state shown Figure 2 When there is wind, the cleaning component 3 moves to the left to scrape the carbon fiber brush 41, while from... Figure 2 The windy condition shown has changed to Figure 1In the windless state shown, the cleaning component 3 will move to the right to scrape the carbon fiber brush 41 again. With this arrangement, the carbon fiber brush 41 may be scraped once every time the fan of the fan coil unit starts or stops or the wind force changes, so as to keep the carbon fiber brush 41 free of dust.

[0023] In some embodiments, the transmission mechanism 2 may be configured as a combination of a gear set and a lead screw and nut. For example, the pivot shaft 10 of the blade 11 may be connected to a first gear 24, and a second gear 25 meshing with the first gear 24 may be connected to a transmission rod 21 formed as a lead screw. The transmission rod 21 is then connected to a nut at one end of the cleaning member 3. Rotation of the blade 11 will cause rotation of the first gear 24, rotation of the second gear 25, and movement of the cleaning member 3 along the D direction. In alternative embodiments, the transmission mechanism 2 may be any suitable transmission device, such as various gears, racks, chains, cams, crankshafts, lead screws, nuts, and other mechanical parts, to achieve the transmission and change of motion direction.

[0024] In some embodiments, blade 11 is a single-blade structure configured to pivot through a pivot angle greater than 70 degrees, for example, to pivot from a vertical position to a horizontal position. Although an exemplary single-blade structure is shown in the illustrated embodiment, in alternative embodiments, the blade may be selected in other forms, such as multiple blades evenly distributed along the circumference, cross-flow blades, or axial flow blades. In this case, the blade may also remain rotating in the presence of wind. In addition, the orientation of the blade's pivot axis may change, and correspondingly, the structures of the transmission mechanism 2 and the cleaning element 3 will also be adapted accordingly.

[0025] On the other hand, the present invention also provides an ion generating device and an air conditioning system, wherein the ion generating device includes a wind-driven cleaning device according to various embodiments, and the fan coil unit of the air conditioning system is provided with the ion generating device according to various embodiments. The wind-driven cleaning device shall be installed in the air duct of the air conditioning system, wherein the airflow ensures that the cleaning component scrapes the carbon fiber brush on the electrode plate of the ion generating device once each time the fan starts or stops.

[0026] The specific embodiments described above are merely for the purpose of more clearly illustrating the principles of the present invention, wherein the various components are clearly shown or described to make the principles of the present invention easier to understand. Various modifications or variations can be readily made to the present invention by those skilled in the art without departing from the scope of the invention. Therefore, it should be understood that all such modifications or variations should be included within the patent protection scope of the present invention.
