Description

Technical Field

[0001] This disclosure relates to the field of air conditioner technology, and more particularly to a filter device and an air conditioner. Background Technology

[0002] In air conditioning systems, filters are the core component for air purification, and their performance directly affects indoor air quality, system energy consumption, and equipment lifespan. However, existing air conditioning filters have significant technical limitations in design and operation, making it difficult to adapt to dynamically changing environmental demands.

[0003] In related technologies, many air conditioner filters are designed and operated in a fixed mode, making it impossible to flexibly adjust them according to actual environmental conditions. Traditional fixed filters often fail to meet the needs of dynamic environments, easily leading to problems such as decreased filtration efficiency and filter clogging, which seriously affect the filter's lifespan and user experience. Utility Model Content

[0004] In view of this, in order to solve the technical problem in the prior art that the filter cannot be flexibly adjusted according to the actual environmental conditions due to the use of a fixed mode, this disclosure provides a filtration device and an air conditioner.

[0013] The support assembly includes a second multi-degree-of-freedom joint, and the second connecting part is rotatably connected to the filter through the second multi-degree-of-freedom joint.

[0014] In one alternative implementation,

[0015] The filtering device includes a roller shutter mechanism, wherein the roller shutter slats of the roller shutter mechanism have an unfolded state and a rolled-up state;

[0016] Specifically, when the roller shutter is in the unfolded state, it covers the upper side of the filter when it is in the second state; when the roller shutter is in the rolled-up state, it is located at the first end of the filter.

[0017] In one alternative implementation,

[0018] The filtration device includes a battery that is electrically connected to the roller shutter mechanism and is used to power the roller shutter mechanism.

[0023] In one alternative implementation,

[0024] An electromagnet is provided at the free end of the roller shutter slat, and the fixed shaft includes an electromagnetic clutch. When the roller shutter slat is in the unfolded state, the electromagnetic clutch is energized and attracts the electromagnet at the free end of the roller shutter slat, so that the free end of the roller shutter slat is connected to the fixed shaft.

[0025] In one alternative implementation,

[0026] The filter device includes a brush head and a guide rail. The brush head is used to brush the filter to clean it. The guide rail extends from a first end to a second end of the filter and is used to guide the movement of the brush head.

[0034] The technical solutions provided by the embodiments of this disclosure can include the following beneficial effects: In this disclosure, the filtration device includes a filter and an adjustment mechanism. The filter is installed in the channel to be filtered through the adjustment mechanism, which can be used to adjust the state of the filter. In a first state, the filter is perpendicular to the axis of the channel to be filtered. In this state, when the gas in the channel to be filtered flows axially, it will all pass through the filter, improving the filtration effect and removing impurities from the gas. In a second state, the filter is parallel to the axis of the channel to be filtered. In this state, when the gas in the channel to be filtered flows axially, the filter does not participate in the filtration. That is, the filter in the filtration device of this disclosure is no longer fixed in the same fixed state, but can be adjusted to allow the filter to participate in filtration or not. Based on the filtration device disclosed herein, the filter's state can be adjusted according to needs. For example, when the environmental conditions do not require filtration, the filter can be adjusted to a second state, preventing it from participating in filtration, thus avoiding ineffective dust accumulation, reducing impurity contamination of the filter screen, extending the filter screen's lifespan, and also avoiding energy consumption caused by the equipment (e.g., air conditioners) used to overcome filtration resistance. When the environmental conditions require filtration, the filter can be adjusted to a first state, thereby achieving reliable filtration of the gas and significantly improving gas cleanliness. This disclosure achieves precise matching between filtration function and environmental requirements through the "participation or non-participation" state adjustment of the filter device. While ensuring filtration effect, it significantly reduces energy consumption and maintenance costs, and better avoids problems such as decreased filtration efficiency and filter screen clogging caused by the filter being in a filtration-participation state for a long time. This extends the filter's lifespan and improves the user experience.

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The following disclosure provides numerous different embodiments or examples for implementing various aspects of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0051] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly.

Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0052] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the number, shape and size of the components in actual implementation.

[0053] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0054] To address the technical problem in the prior art where filters cannot be flexibly adjusted according to actual environmental conditions due to their fixed mode, this disclosure provides a filtration device, an air conditioner, and a control method.

[0055] In this disclosure, the filtration device includes a filter and an adjustment mechanism. The filter is installed in the channel to be filtered via the adjustment mechanism, which can be used to adjust the state of the filter. In a first state, the filter is perpendicular to the axis of the channel to be filtered. In this state, when the gas in the channel flows axially, it passes entirely through the filter, improving the filtration effect and removing impurities. In a second state, the filter is parallel to the axis of the channel to be filtered. In this state, when the gas in the channel flows axially, the filter does not participate in filtration. In other words, the filter in the filtration device of this disclosure is no longer fixed in a single, fixed state, but can be adjusted to allow it to participate in or not participate in filtration. Based on the filtration device disclosed herein, the filter's state can be adjusted according to needs. For example, when the environmental conditions do not require filtration, the filter can be adjusted to a second state, preventing it from participating in filtration, thus avoiding ineffective dust accumulation, reducing impurity contamination of the filter screen, extending the filter screen's lifespan, and also avoiding energy consumption caused by the equipment (e.g., air conditioners) used to overcome filtration resistance. When the environmental conditions require filtration, the filter can be adjusted to a first state, thereby achieving reliable filtration of the gas and significantly improving gas cleanliness. This disclosure achieves precise matching between filtration function and environmental requirements through the "participation or non-participation" state adjustment of the filter device. While ensuring filtration effect, it significantly reduces energy consumption and maintenance costs, and better avoids problems such as decreased filtration efficiency and filter screen clogging caused by the filter being in a filtration-participation state for a long time. This extends the filter's lifespan and improves the user experience.

[0056] In one exemplary embodiment, reference Figures 1 to 3 as well as Figure 6As shown, a filtering device, an air conditioner equipped with the filtering device, and a control method applied to the filtering device and the air conditioner are provided. It should be noted that the air conditioner may include one or more of the aforementioned filtering devices; this is not limited. In this embodiment, the filtering device may include a filter 1 and an adjustment mechanism 2. The filter 1 is installed in the filter channel 300 via the adjustment mechanism 2, and the adjustment mechanism 2 is used to adjust the state of the filter 1.

[0057] In this invention, the regulating mechanism 2 adjusts the filter 1 to a first state, where the filter 1 is perpendicular to the axis of the channel 300 to be filtered. In this state, when the gas in the channel 300 flows axially, it will all pass through the filter 1, improving the filtration effect and removing impurities from the gas. In a second state, the regulating mechanism 2 adjusts the filter 1 to a second state, where the filter 1 is parallel to the axis of the channel 300 to be filtered. In this state, when the gas in the channel 300 flows axially, the filter 1 does not participate in the filtration. In other words, the filter 1 in this filtration device is no longer fixed in a single state, but can be adjusted to participate in or not participate in filtration, thereby improving the adaptability of the filtration device to the environment.

[0058] The adjustment mechanism 2 may include two corresponding support assemblies 21. It should be noted that the axial direction of the filter channel 300 is referred to as the first direction. When the filter 1 is in the first state, and the filter 1 is perpendicular to the axial direction of the filter channel 300, the aforementioned perpendicular direction is referred to as the second direction. In this embodiment, a third direction is also present, and the third direction, the second direction, and the first direction are all mutually perpendicular.

[0059] In the third direction, the two support assemblies 21 can be located on both sides of the filter 1. The filter 1 is installed in the filter channel 300 by the two support assemblies 21 to ensure that the filter 1 is reliably and stably installed in the filter channel 300.

[0060] Each support assembly 21 can be connected to the channel wall of the filter channel 300 via a first multi-degree-of-freedom joint 6. The first multi-degree-of-freedom joint 6 is rotatably connected to the channel wall, and the first multi-degree-of-freedom joint 6 is also rotatably connected to the support assembly 21. Based on this, the support assembly 21 can rotate relative to the channel wall, thereby driving the filter 1 to rotate relative to the channel wall, so that the filter 1 switches between a first state and a second state.

[0061] Each support assembly 21 may include a first support portion 211, a second support portion 212, a first connecting portion 213, and a second connecting portion 214. The first support portion 211 is rotatably connected to a first multi-degree-of-freedom joint 6, meaning the support assembly 21 is fixedly connected to the first multi-degree-of-freedom joint 6 via the first support portion 211. The first multi-degree-of-freedom joint 6 is fixedly connected to the filter 1. The first support portion 211 is fixedly connected to the first connecting portion 213, the first connecting portion 213 is rotatably connected to the second support portion 212, the second support portion 212 is fixedly connected to the second connecting portion 214, and the second connecting portion 214 is rotatably connected to the filter. Based on this, the filter 1 can switch between a first state and a second state through the mutual cooperation between the first support portion 211, the second support portion 212, the first connecting portion 213, the second connecting portion 214, and the first multi-degree-of-freedom joint 6, so that the filter 1 can participate in filtration or not participate in filtration according to actual needs.

[0062] The first support portion 211 and the second support portion 212 can be rod-shaped structures, while the first connecting portion 213 and the second connecting portion 214 can be plate-shaped structures. The first support portion 211 and the first connecting portion 213 can be fixedly connected by fasteners such as screws or bolts, or by snap-fitting, bonding, or welding; there is no limitation on this. The connection method between the second support portion 212 and the second connecting portion 214 can refer to the connection method between the first support portion 211 and the first connecting portion 213, and will not be elaborated further.

[0063] The support assembly 21 may include a linkage pivot 216. The first connecting part 213 is rotatably connected to the second support part 212 via the linkage pivot 216 to ensure the reliability of the rotatable connection and mutual rotation between the two. The support assembly 21 may also include a second multi-degree-of-freedom joint 215, which may have the same structure as the first multi-degree-of-freedom joint 6 or may be different, and is not limited thereto. The second connecting part 214 is rotatably connected to the filter 1 via the second multi-degree-of-freedom joint 215. The second multi-degree-of-freedom joint 215 is rotatably connected to the channel wall and fixedly connected to the filter 1. Based on this, the adjustment mechanism 2 can switch between the first state and the second state of the filter 1 through the two multi-degree-of-freedom joints (i.e., the first multi-degree-of-freedom joint 6 and the second multi-degree-of-freedom joint 215) and the first support part 211, the second support part 212, the first connecting part 213 and the second connecting part 214, and can make the filter 1 stably in the first state or the second state. That is, when filter 1 switches to the first state, it can remain stably in the first state; when filter 1 switches to the second state, it can remain stably in the second state.

[0064] In some implementations...

[0065] When filter 1 is perpendicular to the axial direction of the channel 300 to be filtered (i.e. filter 1 is in the first state), the direction is defined as follows: the first direction is the thickness direction of filter 1 (perpendicular to the surface of filter 1, consistent with the axial direction of the channel 300 to be filtered, i.e. the main airflow direction); the second direction is the length direction of filter 1 (extending along the surface of filter 1, perpendicular to the first direction); the third direction is the width direction of filter 1 (extending along the surface of filter 1, perpendicular to both the first and second directions).

[0066] In this embodiment, the filtration device may include a filter 1 and an adjustment mechanism 2. The adjustment mechanism 2 drives the filter 1 to switch between a "first state (perpendicular to the channel axis, filtration state)" and a "second state (parallel to the channel axis, non-filtration state)" through two symmetrically distributed support assemblies 21 (distributed on both sides of the filter 1 along the third direction).

[0067] The channel wall of the filter channel 300 can be a double-layered wall, and the support assembly 21 can be located within the cavity 310 formed by the channel wall of the filter channel 300. Each support assembly 21 includes a first multi-degree-of-freedom joint 6, a first support portion 211, a second support portion 212, a first connecting portion 213, a second connecting portion 214, a linkage pivot 216, and a second multi-degree-of-freedom joint 215. The first multi-degree-of-freedom joint 6 is rotatably connected to the inner wall of the filter channel 300, and the rotation axis is parallel to a third direction, which can drive the support assembly 21 to swing (the swing angle is, for example, 0°-90°) or rotate (for example, 360° rotation) around the third direction, and is fixedly connected to the first support portion 211. The first support portion 211 has a rod-like structure, one end of which is fixed to the first multi-degree-of-freedom joint 6 (e.g., bolted connection), and the other end is connected to the first connecting portion 213. The first connecting part 213 has a plate-like structure and is rotatably connected to the second support part 212 via a linkage pivot 216 (the rotation axis is parallel to a third direction). It can rotate around the third direction to realize the folding and unfolding of the support. The second support part 212 has a rod-like structure, with one end rotating to the first connecting part 213 via the linkage pivot 216, and the other end connected to the second connecting part 214. The second connecting part 214 has a plate-like structure and is rotatably connected to the edge of the filter 1 via a second multi-degree-of-freedom joint 215 (the rotation axis is parallel to a third direction). It rotates synchronously with the filter 1 around the third direction.

[0068] In this embodiment, the two support assemblies 21 can symmetrically clamp the filter 1 on both sides of the width direction along the third direction, and the rotation axes of all rotating parts are parallel to the third direction, forming a stable adjustment mechanism 2 of "single-sided drive + symmetrical linkage", thereby reliably and stably adjusting the state of the filter 1 and realizing its switching between the first state and the second state.

[0069] It should be noted that the adjustment mechanism 2 can be any combination of structures other than those described above, as long as it can enable the filter 1 to switch between the first and second states. The specific combination of its structures is not limited.

[0070] In this embodiment, the state of filter 1 can be adjusted based on environmental conditions and user needs. For example, when the environmental conditions of filter 1 do not require filtration, the filter device can be controlled to be in a non-filtration mode. In this mode, the filter can be adjusted to a second state by adjusting the structure, so that filter 1 is parallel to the airflow direction, so that filter 1 does not participate in filtration, avoiding ineffective dust accumulation, reducing impurities from contaminating the filter screen, extending the service life of the filter screen, and also avoiding energy consumption generated by the device to which filter 1 is applied (e.g., an air conditioner) to overcome filtration resistance. When the environmental conditions of filter 1 require filtration, the filter device can be controlled to be in a filtration mode. In this mode, the filter 1 can be adjusted to a first state by adjusting mechanism 2, so that filter 1 is perpendicular to the airflow direction, thereby achieving reliable filtration of the gas and significantly improving gas cleanliness.

[0071] This embodiment achieves precise matching between filtration function and environmental requirements by adjusting the state of the filter device to "participate in or not participate in filtration". While ensuring filtration effect, it significantly reduces energy consumption and maintenance costs, and can better avoid problems such as decreased filtration efficiency and filter clogging caused by the filter 1 being in the filtration participation state for a long time. This can extend the service life of the filter 1 and improve the user experience.

[0072] In one exemplary embodiment, reference Figures 1 to 6 As shown, a filtration device is provided, as well as an air conditioner equipped with the filtration device, and a control method applied to the filtration device and the air conditioner. In this embodiment, the filtration device may include a roller shutter mechanism 3, wherein the roller shutter slats 31 of the roller shutter mechanism 3 have an unfolded state and a rolled-up state.

[0073] In the unfolded state, the roller shutter 31 covers the upper side of the filter 1 when it is in the second state, thus protecting the filter 1. Impurities falling onto the filter 1 prevent contamination and clogging, better ensuring the filtration effect and extending its service life. In the rolled-up state, the roller shutter 31 is located at the first end of the filter 1. This first end can be one end along the length of the filter 1. In the first state, the first end can be the upper end of the filter 1. In this case, when the roller shutter 31 needs to be unfolded, it is easier to unfold under gravity. It should be noted that when the roller shutter 31 is in the rolled-up state, it no longer obstructs or protects the filter 1, allowing the filter 1 to effectively participate in filtration and purify the gas.

[0074] The filter device may also include a battery (not shown in the figure), which may be a rechargeable battery. The battery is electrically connected to the roller shutter mechanism 3 to supply power to the roller shutter mechanism 3. When the filter device does not need to participate in filtration, it can be turned off, that is, the electrical connection between the filter device and the power source can be disconnected. In this case, the battery can supply power to the roller shutter mechanism 3, thereby adjusting the state of the roller shutter slats 31 as needed to meet the switching between the unfolded state and the rolled-up state of the roller shutter slats 31.

[0075] The roller shutter mechanism 3 may include a drive wheel 32. The drive wheel 32 is located at the first end of the filter 1 and is used to drive the roller shutter slats 31 to switch between an unfolded state and a rolled-up state. The drive wheel 32 may include a drive motor and a wheel body, and the drive motor may be electrically connected to a battery. For example, when the roller shutter slats 31 need to switch from a rolled-up state to an unfolded state, the drive motor can drive the wheel 32 to rotate clockwise. In this case, the roller shutter slats 31 unfold under the action of the drive wheel 32. When the roller shutter slats 31 need to switch from an unfolded state to a rolled-up state, the drive motor can drive the wheel 32 to rotate counterclockwise. In this case, the roller shutter slats 31 can roll up under the action of the drive wheel 32 to house the roller shutter slats 31 at the first end of the filter 1.

[0076] The roller shutter mechanism 3 includes a fixed shaft 33 located at the second end of the filter 1. The first and second ends of the filter 1 are opposite ends of the filter 1. That is, when the filter 1 is in its first state, the first end is the upper end of the filter 1, and the second end is the lower end of the filter 1. When the roller shutter 31 is in its unfolded state, the free end of the roller shutter 31 is connected to the fixed shaft 33, so that the roller shutter 31 completely covers the filter 1, better protecting the filter 1 from contamination and clogging.

[0077] The free end of the blind slat is equipped with an electromagnet, and the fixed shaft 33 may include an electromagnetic clutch. The electromagnetic clutch can be electrically connected to a battery. When the blind slat 31 is in the unfolded state, the electromagnetic clutch is energized, attracting the electromagnet at the free end of the blind slat 31, thereby connecting the free end of the blind slat 31 to the fixed shaft 33 and ensuring the blind slat 31 is stably in the unfolded state. After the free end of the blind slat 31 is attracted and connected to the fixed shaft 33, the blind slat 31 can completely cover the filter 1 and enclose the filter 1 on one side of the blind slat 31, thus achieving the purpose of shielding and protecting the filter 1.

[0078] In this embodiment, when the filter device is in filtration mode, the roller shutter 31 can be controlled to be in a rolled-up state to avoid obstructing the filter 1, thus ensuring that the filter 1 participates in the filtration process and guaranteeing the filtration effect. When the filter device is in non-filtration mode, the roller shutter 31 can be controlled to be in an unfolded state to shield and protect the filter 1, preventing impurities from falling into the filter 1 and affecting its filtration effect, thereby extending the service life of the filter 1.

[0079] This embodiment solves the problems of dust accumulation and short lifespan of traditional filters 1 in non-filtration mode by setting up a roller shutter mechanism 3, while ensuring high efficiency and response speed in filtration mode. In other words, this embodiment extends the lifespan of filters 1 and reduces maintenance costs by dynamically adapting to filtration / non-filtration modes. It is also flexible in installation and highly reliable, making it particularly suitable for air conditioners in dusty and complex environments (such as shopping malls, factories, and subway stations). This significantly improves the service life of filters 1 and reduces costs.

[0080] In one exemplary embodiment, reference Figures 1 to 6 As shown, a filtration device, an air conditioner equipped with the filtration device, and a control method applied to the filtration device and the air conditioner are provided. In this embodiment, the filtration device may include a brush head 4 and a guide rail 5. The brush head 4 is used to brush the filter 1 to clean it. The guide rail 5 extends from a first end to a second end of the filter 1 and guides the movement of the brush head 4 to ensure that the brush head 4 moves in a set direction, thereby better ensuring the cleaning effect on the filter 1.

[0081] The filter device can have a cleaning mode and a non-cleaning mode. When the filter device is in the cleaning mode, the filter 1 can be controlled to be in the first state. After the filter 1 is in the first state, the roller shutter slats 31 of the roller shutter mechanism 3 can be controlled to be in the unfolded state. Then, the brush head 4 is controlled to reciprocate along the guide rail 5 to clean the filter 1.

[0082] It should be noted that the brush head 4 can be located on the side of the roller shutter 31 facing the filter 1, that is, the brush head 4 can be located between the roller shutter 31 and the filter 1. When the roller shutter 31 is in the unfolded state, the brush head 4 can prevent dust and other impurities generated during cleaning of the filter 1 from flying around. In addition, when the filter 1 is in the first state, the roller shutter 31 can be located on the downstream side of the filter 1, that is, the roller shutter 31 is located on the side of the filter 1 facing the user. Based on this, when the brush head 4 cleans the filter 1, it can prevent dust and other impurities from being transmitted to the user, thus improving the user experience.

[0083] The filtration device may include an airflow generator (not shown in the figure), which is located at the first end of the filter 1 and has its outlet facing the second end of the filter 1. The airflow generator is used to generate airflow from the first end of the filter 1 toward the second end.

[0084] When the filter is in cleaning mode, after the control shutter 31 is in the unfolded state, the airflow generator can be controlled to operate, that is, the airflow generator generates airflow from the first end of the filter 1 to the second end to clean the filter 1. When the filter includes a brush head 4 and a guide rail 5, the airflow generator and the brush head 4 work together to improve the cleaning efficiency and effect of the filter 1, better clean the filter 1, better ensure the filtration effect of the filter 1, better avoid clogging of the filter 1, and better extend the service life of the filter 1.

[0085] In addition, in this embodiment, the filter device may also include a dust collector 7 for collecting dust and other impurities. When the filter 1 is in its first state, the dust collector 7 may be located below the filter 1. That is, the dust collector 7 may be located at the first end of the filter 1. When the filter device is in cleaning mode, the filter 1 is cleaned by the cooperation of the brush head 4 and the airflow generator. The roller shutter 31 prevents dust and other impurities generated during cleaning from flying around. Simultaneously, the cooperation of the airflow generator and the dust collector 7 drives the dust and other impurities generated during cleaning to the dust collector 7, thereby achieving the collection of dust and other impurities.

[0086] In this embodiment, the mechanical cleaning of the brush head 4 combined with the blowing of the airflow generator improves the cleaning efficiency and effectiveness of the filter 1. Furthermore, the obstruction by the roller shutter 31 prevents dust and other impurities from flying around, further enhancing the user experience. Moreover, the coordination between the roller shutter 31 and the dust collector 7, along with the direction of the airflow generator's blowing, allows for better collection of dust and other impurities from the filter 1 into the dust collector 7, achieving a better cleaning effect. In other words, this embodiment, through the integrated design of the roller shutter 31 obstruction, the mechanical cleaning of the brush head 4, the airflow blowing of the airflow generator, and the centralized dust collection of the dust collector 7, effectively solves the problems of low cleaning efficiency, secondary pollution, and high maintenance costs associated with traditional filters 1. It achieves more efficient cleaning, extends the service life of the filter device and the air conditioner equipped with it, and significantly improves the user experience. It is particularly suitable for scenarios with stringent air quality requirements and high maintenance costs, such as hospitals and electronics factories.

[0087] In one exemplary embodiment, reference Figures 1 to 6 As shown, a filtration device, an air conditioner equipped with the filtration device, and a control method applied to the filtration device and the air conditioner are provided. In this embodiment, the filtration device may include a filter 1, an adjustment mechanism 2, a first multi-functional integrated device 10, and a second multi-functional integrated device 20. The first multi-functional integrated device 10 is located at the first end of the filter 1, and the second multi-functional integrated device 20 is located at the second end of the filter 1.

[0088] The first multi-functional integrated device 10 may include a drive wheel 32 and a roller shutter 31, with the roller shutter 31 rolled up and retracted onto the drive wheel 32 in the rolled-up state. The second multi-functional integrated device 20 may include a fixed shaft 33, with the free end of the roller shutter 31 in the unfolded state, which can be magnetically connected to the fixed shaft 33. The aforementioned drive wheel 32, roller shutter 31, and fixed shaft 33 constitute the roller shutter mechanism 3 of the filter device. It should be noted that the roller shutter mechanism 3 may include other structures besides the aforementioned structure, and this is not limited. In addition, when the filter 1 is in the first state, a dust collector 7 is provided below the second multi-functional integrated device 20, and the bottom of the second multi-functional integrated device 20 may be provided with a perforated structure to allow dust and other impurities to fall into the dust collector 7 through the perforated structure.

[0089] In this embodiment, the air conditioner may include at least one of the above-described filtering devices. For example, the air conditioner may include two filtering devices, referred to as a primary filter 100 and a secondary filter 200, respectively.

[0090] When the air conditioner includes two filtration devices, the secondary filtration device 200 is located downstream of the primary filtration device 100, and the filter 1 of the primary filtration device 100 includes a coarse filter 1, while the secondary filtration device 200 includes a medium-high efficiency filter 1. That is, the filtration effect of the downstream secondary filtration device 200 is better than that of the upstream primary filtration device 100.

[0091] In this embodiment, both the primary filter 100 and the secondary filter 200 can be located within the filtration channel 300 formed by the air conditioner's unit casing. After the air conditioner is turned on, the primary filter 100 can be controlled to be in a first state to filter the gas passing through the filtration channel 300. Furthermore, the air intake operating condition coefficient of the secondary filter 200 can be calculated and determined, and then the state of the secondary filter 200 can be controlled based on this coefficient.

[0092] When the inlet air condition coefficient is less than or equal to the set threshold, it indicates that the gas after passing through the primary filter 100 meets the requirements and does not require secondary filtration. In this case, the secondary filter 200 can be controlled in the second state, so that the secondary filter 200 does not participate in filtration. When the inlet air condition coefficient is greater than the set threshold, it indicates that the gas after passing through the primary filter 100 still needs secondary filtration. In this case, the secondary filter 200 can be controlled in the first state, so that the secondary filter 200 participates in filtration to ensure the filtration effect of the gas.

[0093] In other words, after the air conditioner unit is turned on, natural air enters the filter channel 300 formed by the unit through the air inlet 600. The filter 1 of the primary filter device 100 within the unit is typically kept in its first state (i.e., open state, also known as folded state). The first multi-functional integrated device 10 and / or the second multi-functional integrated device 20 may be equipped with differential pressure sensors and air identification sensors to collect real-time differential pressure data and dust concentration information of the filter screen 1. Specific parameters may include inlet airflow Q, particulate matter concentration C, and volatile organic compound (VOC) concentration, and the data can be transmitted to the secondary filter device 200. It should be noted that the inlet airflow Q can be determined based on pressure drop or other methods, without limitation. For example, a heat exchange mass flow sensor can be used to measure the heat carried away by the gas as it flows through the heating element to determine the flow rate.

[0094] In this system, the filter 1 of the secondary filter 200 is typically kept in a second state (i.e., closed state, also known as the deployed state). The first multi-functional integrated device 10 and / or the second multi-functional integrated device 20 of the secondary filter not only perform secondary identification of the gas passing through the primary filter 100, but also receive and analyze signals from the multi-functional integrated device of the primary filter 100, and perform dual verification by combining the data collected by its own sensors. The intelligent module of the secondary filter 200 can comprehensively analyze the air intake operating parameters transmitted by the primary filter 100 and the secondary air intake data monitored by itself, and perform data verification through a preset algorithm. When the calculation results of the two signals are consistent or the deviation is within the allowable range (e.g., the deviation is less than or equal to 10%), the intelligent module can determine that the signal is accurate and will proceed to the next step.

[0095] Specifically, when the air intake operating coefficient S of the secondary filter 200 is less than or equal to the set threshold T (S=αQ+βC+γVOCs, where α, β, and γ are weighting coefficients, for example α=0.4, β=0.3, γ=0.3), the filter 1 of the secondary filter 200 will remain in the second state; when the air intake operating coefficient S of the secondary filter 200 is greater than the set threshold T, the filter 1 of the secondary filter 200 will start working, that is, control the filter 1 of the secondary filter 200 to switch to the first state.

[0096] Among them, the filter 1 of the secondary filtration device 200 differs significantly in filtration efficiency from the filter 1 of the primary filtration device 100. The filter 1 of the primary filtration device 100 typically uses a coarse filter 1, such as a G4 coarse-fine filter 1, which has a low initial pressure drop (≤30Pa) and a high dust holding capacity (≥600g / ㎡), effectively filtering most particulate matter and impurities. The filter 1 of the secondary filtration device 200, however, can use more efficient filter materials, such as a chemical filter 1 or H13 grade glass fiber filter paper, specifically designed to purify specific chemical substances (such as industrial pollutants, harmful gases, etc.). These chemical substances are usually not continuous but appear periodically; therefore, the status of the filter 1 of the secondary filtration device 200 can be intelligently adjusted according to actual operating conditions to ensure efficient operation.

[0097] In this embodiment, the natural air, after passing through the primary filter 100 and the secondary filter 200, will enter other functional sections 400 of the unit for further processing. These other functional sections 400 may include, for example, a humidity control section 400, a temperature control section 400, or other special processing sections 400, and are not limited thereto. Finally, the gas processed by the other functional sections 400 can be output to the air conditioning duct through the air outlet section 500 for use by subsequent users.

[0098] When the air conditioner unit is turned off, all functional sections 400 except for the primary filter 100 and secondary filter 200 can be shut down. The batteries inside the filters can still operate for a period of time to ensure the normal start of the filter's cleaning mode. During this stage, the differential pressure sensor and optical dust sensor in the multi-functional integrated device of the primary filter 100 and secondary filter 200 can work together to monitor the amount of impurities attached to the filter 1 and the degree of clogging in real time, and calculate the A value (airflow-resistance characteristic parameter) (A=K1×ΔP+K2×C+K3×VOCs, for example, K1=0.5, K2=0.3, K3=0.2, ΔP is the differential pressure value, C is the particulate matter concentration, and VOCs is the volatile organic compound concentration). It should be noted that since different types of filters 1 have different adsorption characteristics for impurities, the specific definition and calculation method of the A value may also differ, but this is not limited.

[0099] Specifically, when the value of A is less than or equal to a preset specific value (e.g., A≤50), filter 1 will automatically shut off. That is, the adjustment mechanism 2 of the filter device can adjust filter 1 to a second state, and the filter device enters a standby state, subsequently cutting off battery power to save energy. When the value of A is greater than the preset specific value (e.g., A>50), filter 1 will remain in the first state and activate the cleaning mode of the filter device.

[0100] It should be noted that, in order to prevent dust generated during the cleaning process from spreading to other functional sections 400, in cleaning mode, the filter 1 is first ensured to be in the first state so that the roller shutter mechanism 3 can unfold under the combined action of the drive wheel 32 and the gravity of the roller shutter slat 31 until it is in complete contact with the fixed shaft 33 in the second multi-functional integrated device 20 below, forming a sealed barrier. The electromagnetic clutch of the second multi-functional integrated device 20 is energized after the roller shutter mechanism 3 is opened, and the fixed shaft 33 attracts the electromagnet at the free end of the roller shutter slat 31, ensuring that the roller shutter slat 31 is completely closed. Then, the brush head 4 can start multiple reciprocating movements from top to bottom, that is, the brush head 4 can reciprocate along the guide rail 5 to thoroughly clean the filter screen of the filter 1. At the same time, the small airflow generator in the first multi-functional integrated device 10 can be turned on to generate directional high-pressure airflow, which, in conjunction with the cleaning action of the brush head 4, blows away the separated dust and other impurities through the combined action of wind and gravity. The hollow structure below the second multi-functional integrated device 20 allows blown-off dust and other impurities to fall directly into the dust collector 7 in the base of the filter device. When the dust sensor built into the dust collector 7 detects that the amount of dust and other impurities in the dust collector 7 reaches the preset capacity (e.g., ≥500g), it can trigger the flashing of an indicator light to notify the staff to promptly remove the dust collector 7 from the side of the unit for replacement or cleaning.

[0101] After the cleaning of the filter device is completed, the integrated sensor inside the filter device will transmit a signal to cause the adjustment mechanism 2 to fold the bracket, thereby adjusting the filter 1 to the second state. That is, the filter device can adjust the filter 1 to the second state through the coordinated work of the first bracket part 211, the second bracket part 212, the first connecting part 213, the second connecting part 214, the first multi-degree-of-freedom joint 6, the second multi-degree-of-freedom joint 215 and the linkage pivot 216, so as to complete the unfolding and resetting of the filter 1.

[0102] When filter 1 is in its second state, the filter's battery will continue to supply power for a period of time to ensure that the shutter slats 31 remain closed, preventing dust and other impurities in the outside air from entering the filter 1. When the unit is powered back on, the electromagnetic clutch will be de-energized, and the shutter mechanism 3 will retract the shutter slats 31, causing them to switch to the rolled-up state. The primary filter 100, through the coordinated operation of the first support part 211, the second support part 212, the first connecting part 213, the second connecting part 214, the first multi-degree-of-freedom joint 6, the second multi-degree-of-freedom joint 215, and the linkage pivot 216, will fold filter 1 to its working position, placing filter 1 in its first state. At this time, the secondary filter 200 will comprehensively evaluate its current air intake condition coefficient S and then control the state of filter 1 in the secondary filter 200 to adapt to the new operating requirements.

[0103] In this embodiment, filter 1 adopts a foldable design, and the switching between the first and second states is achieved through the cooperation of a motor and an adjustment mechanism 2. This design not only allows for flexible adjustment of the filtration area according to actual needs, but also allows the filter screen to be closed during cleaning, forming an independent cleaning space and avoiding secondary contamination from impurities during the cleaning process. Moreover, the foldable and unfoldable filter 1 facilitates cleaning and replacement. This design overcomes the limitations of traditional fixed filters 1, allowing filter 1 to maintain its filtration performance without frequent screen replacements during long-term use, requiring only simple cleaning to restore filtration efficiency, thereby reducing maintenance costs and improving system operating efficiency. For example, when air quality is poor, filter 1 can automatically fold to increase the filtration area and improve filtration efficiency; while when air quality is good, filter 1 can automatically unfold to reduce resistance and lower energy consumption.

[0104] The filter unit incorporates an automatic cleaning system (such as a brush head 4 and an airflow generator) that monitors the filter screen status in real time. When excessive dust accumulation is detected, the system automatically initiates a cleaning process, integrating dust detection, cleaning, and discharge. This functionality reduces the frequency and cost of manual maintenance and ensures the continuous and efficient operation of the filter. Furthermore, regular filter cleaning effectively prevents equipment overload caused by dust blockage, extending the lifespan of the air conditioning system and reducing equipment replacement and maintenance costs. In this embodiment, differential pressure feedback optimizes the cleaning frequency, allowing the filter unit to minimize energy consumption while maintaining filtration efficiency, achieving highly efficient and energy-saving operation.

[0105] This embodiment provides an intelligent, efficient, and long-life openable and foldable filter device, as well as an air conditioner equipped with the above-mentioned filter device, which can significantly improve the operating performance and environmental friendliness of the filter device and the air conditioner, and has broad application prospects and market value.
