[0002] As people's living standards continue to improve and their health awareness increases, air purifiers have gradually become an indispensable household appliance. However, for families with pets, pets continuously shed a large amount of hair, dander, and dust during their daily activities. When air flows through the purifier, this hair and dust are easily captured by the filter and adhere to its surface or the gaps between the fibers.

[0003] To maintain purification effectiveness, users need to clean or replace the filter regularly. Since the filter is usually fixed inside the air purifier, users must disassemble it for cleaning or washing when necessary. However, this process can cause hair, dander, or other dirt attached to the filter to fall off, or the user's hands to become contaminated, leading to secondary pollution and inconvenience for the user, thus reducing the overall experience of filter replacement.

[0032] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0033] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0034] This utility model embodiment provides an air purification device, a filter assembly, and an unwinding unit for an air conditioning component, wherein both the air purification device and the filter assembly include an unwinding unit for the air conditioning component. Of course, the air purification device may also include a filter assembly with an unwinding unit for the air conditioning component.

[0035] The following describes in detail, with reference to the accompanying drawings, the specific structure of a filter component provided by this utility model and its corresponding technical effects.

[0036] Please refer to Figures 1-3 The present invention provides a filter assembly 1 including an air conditioning component unwinding unit 100 and an air conditioning component 200. The air conditioning component unwinding unit 100 includes a mounting housing 110, a winding portion, and an air conditioning component 200. The winding portion is rotatable, and the air conditioning component 200 is made of soft material, meaning that the air conditioning component 200 can deform under external force. At least a portion of the air conditioning component 200 is fixed to the winding portion and can be wound up or unwound from the winding portion by the rotation of the winding portion.

[0037] Specifically, in this embodiment, the air conditioning component 200 can be understood as a sheet-like structure with a certain length and width that can filter, intercept, or adsorb dirt or gases in the air. Because the air conditioning component 200 is soft, it can be easily wound onto the winding section. It should be noted that the air conditioning component 200 being soft means that it can be rolled up and straightened without damage, thus allowing it to be stored and unfolded by the winding section. Furthermore, the air conditioning component 200 itself can be a sheet with a certain thickness (usually less than 10mm) or a sheet as thin as paper. As long as it can be stored and unfolded by the winding section, it is acceptable.

[0038] In detail, the winding part is a winding column 120, which is mounted on the mounting shell 110 and can rotate relative to the mounting shell 110 around its own axis. The winding column 120 winds the air conditioning component 200, and the winding column 120 can drive the air conditioning component 200 to wind, and the air conditioning component 200 can drive the winding column 120 to rotate. It should be noted that the winding column 120 is set in a cylindrical shape, but in other embodiments, the winding part can also be formed into a prism or other shapes. Of course, it can also be provided with a box-shaped outer shell (with an opening on the outer shell for the air conditioning component 200 to extend out) to improve aesthetics and modularity.

[0039] In other words, the air conditioning component 200 can be wound a preset number of turns onto the winding post 120. After a certain period of use, the air conditioning component 200 will accumulate a significant amount of dirt, which can be understood as including hair, dander, dust, and other debris. The user can extend the air conditioning component 200 wound on the winding section by driving the winding section to achieve the air conditioning effect. At the same time, the used air conditioning component 200 can be wound up and replaced to use a new air conditioning component 200.

[0040] For details, please refer to Figures 1-2 In this embodiment, the unwinding unit 100 of the air conditioning component includes two winding posts 120, which are respectively a take-up post 122 and an unwinding post 121. Both the unwinding post 121 and the take-up post 122 are used to connect to the air conditioning component 200.

[0041] In detail, the two ends of the sheet-like air conditioning element 200 are connected to the unwinding column 121 and the take-up column 122, respectively. A portion of the air conditioning element 200 can be pre-wound onto the unwinding column 121 a certain number of turns to ensure that the unwinding column 121 has enough air conditioning elements 200 for multiple uses. The end of the air conditioning element 200 away from the unwinding column 121 can be connected to the take-up column 122. The take-up column 122 is used to drive the air conditioning element 200 during the winding process, thereby causing the air conditioning element 200 to drive the unwinding column 121 to unwind (i.e., unfold) the air conditioning element 200. It should be noted that the air conditioning component 200 is connected to the unwinding column 121 and the rewinding column 122 at both ends. This connection can be designed to be in the original state during production, or the unwinding column 121 and the rewinding column 122 can be equipped with a mechanism for connecting the air conditioning component 200, such as a fastener, Velcro, or sticker, so that the air conditioning component 200 can be detachably attached to or fixed to the unwinding column 121 and the rewinding column 122 for easy replacement.

[0042] The air conditioning component 200, serving as a movable filter medium, is connected at both ends to a take-up column 122 and an unwind column 121, forming a continuous transmission path. When external power or user operation drives the take-up column 122 to rotate, the take-up column 122 begins to wind up the air conditioning component 200. As the winding action progresses, the air conditioning component 200 is gradually pulled out from the unwind column 121 side and wound onto the take-up column 122. During this process, because the air conditioning component 200 remains connected to the unwind column 121, the movement of the air conditioning component 200 will drive the unwind column 121 to rotate synchronously, causing it to release the wound portion, thus achieving the active unfolding of the air conditioning component 200.

[0043] In essence, this embodiment configures the two winding columns 120 as winding and unwinding units with a cooperative action relationship, enabling the air conditioning component 200 to achieve continuous and stable unwinding coordination during the winding operation. This structural design eliminates the need for an additional power source to independently control the unwinding action; instead, it utilizes the tension generated during the winding process to naturally trigger the unwinding response, thereby simplifying the overall mechanical structure and improving operational reliability.

[0044] Understandably, the portion of the air conditioning component 200 located between the unwinding column 121 and the winding column 122 can be considered as being positioned on the air inlet side of the filter element, directly contacting the external environment to achieve the filtration effect. The air conditioning component 200 wound onto the winding column 122 is the used, dirty air conditioning component 200, while the air conditioning component 200 wound onto the unwinding column 121 is the clean air conditioning component 200 ready for use.

[0045] Specifically, in this embodiment, the mounting shell 110 includes two end plates 111, which are arranged opposite to each other, and the two ends of the winding column 120 are rotatably connected to the two end plates 111 respectively. That is, the two ends of the take-up column 122 are rotatably connected to the two end plates 111 respectively, and the two ends of the unwind column 121 are also rotatably connected to the two end plates 111 respectively.

[0046] The two end plates 111 are arranged in a relatively opposite manner to form the basic structure of the support frame, providing the necessary structural stability and assembly reference for the unwinding unit 100 of the entire air conditioning component, so that the winding column 122 and the unwinding column 121 can achieve stable rotational movement with their own axes as the center and under the common support of the two end plates 111.

[0047] This embodiment can be understood as follows: by designing the mounting housing 110 to include two opposing end plates 111, and rotatably connecting the two ends of the take-up column 122 and the winding column 120 to these two end plates 111 respectively, a symmetrical and reliable rotary support structure is constructed. This structure not only ensures the coaxiality and operational stability of the winding column 120 during operation, but also effectively avoids uneven force distribution or vibration problems that may be caused by unilateral support, thereby improving the smoothness and reliability of the air conditioning component 200 during the winding process. Simultaneously, it allows for a separate modular design to adapt to use in various air purification devices.

[0048] It should be noted that "rotatable connection" here is limited to a mechanical connection that allows the winding column 120 to rotate relative to the end plate 111 about its own axis. Specific implementations can include, but are not limited to, conventional methods such as using a rotating shaft and bearing, a rotating pair formed by inserting a rotating shaft into a slot, or a snap-fit ​​rotating structure, as long as the rotation function is satisfied, and are not limited to a specific assembly structure. Furthermore, in this embodiment, the winding column 120 is detachably mounted to the mounting housing; that is, the winding column 120 is detachably mounted to the end plate, facilitating user disassembly and reassembly of the winding column 120 to replace the air conditioning component 200. It should also be emphasized that the detachable mounting of the winding column 120 to the mounting housing does not necessarily mean that the winding column 120 is directly mounted on the mounting housing; it can also be mounted on a part of the mechanism connected to the mounting housing (i.e., indirect mounting) to achieve fixation.

[0049] Please refer to Figure 1 and Figure 4 Optionally, the end plate 111 can be a circular or rectangular plate structure.

[0050] Please continue to refer to this. Figures 1-3 In this embodiment, the end plate 111 is annular. This means that its overall outline is closed circumferentially and has a centrally symmetrical or approximately symmetrical geometric shape. This annular structure provides a basic configuration for overall installation and rotational support, allowing the two ends of the winding column 122 and the unwinding column 121 to be rotatably connected to the two oppositely arranged end plates 111, thereby ensuring the stable rotation of the winding column 120 in the axial direction.

[0051] In this embodiment, at least one of the two end plates 111 is further provided with a guide portion 130 for guiding the air conditioning component 200 to move along the unwinding direction on the mounting housing 110.

[0052] Specifically, in practical applications, when the air conditioning component 200 unwinds from the winding post 120, its movement path needs to be effectively constrained to avoid phenomena such as deviation, wrinkling, or jamming. To this end, at least one of the two end plates 111 is provided with a guide portion 130, which acts as a structured guiding mechanism to limit the movement direction of the air conditioning component 200. During this process, one end or edge of the air conditioning component 200 can be embedded in or fitted to the guide portion 130, so that its movement along the unwinding direction is constrained by the spatial boundary of the guide portion 130, thereby maintaining a stable trajectory.

[0053] In detail, in this embodiment, the guide portion 130 includes a guide groove 131 that extends circumferentially along the end plate 111, meaning its extension path follows the arcuate contour of the outer or inner edge of the end plate 111, forming a curved channel. The guide groove 131 is configured to accommodate the end of the air conditioning component 200, meaning that during the unfolding or rewinding process from the winding post 120, the edge portion of the air conditioning component 200 can be embedded and slid within the guide groove 131.

[0054] During this process, when the air conditioning component 200 moves with the rotation of the take-up column 122 or the unwind column 121, its end is limited by the sidewall of the guide groove 131, thus constraining its movement along a predetermined trajectory and preventing deviation, wrinkling, or jamming. This circumferentially extending guide groove 131 design is particularly suitable for the annular layout formed by the circular end plate 111, and can naturally match the arc-shaped travel path of the filter screen during rotation and unfolding, making the movement of the air conditioning component 200 in the unwinding direction smoother and more controllable.

[0055] This embodiment can be understood as follows: by using the guide groove 131 extending circumferentially along the end plate 111 and placing it on the annular end plate 111, continuous guidance and position holding of the end of the air conditioning component 200 during dynamic operation are achieved. In other words, this embodiment improves the smoothness and reliability of the movement of the air conditioning component 200 by utilizing the circumferential extension characteristics of the guide groove 131 in coordination with the overall annular structure of the end plate 111.

[0056] In detail, in this embodiment, both end plates 111 are provided with guide grooves 131, and the openings of the guide grooves 131 on the two end plates 111 are arranged opposite each other. This means that the openings of the two end plates are arranged in a direction that brings them closer to each other, thereby forming a symmetrical and opposite guiding structure on both sides of the mounting housing 110. During this process, the two ends of the air conditioning component 200 are respectively embedded in the guide grooves 131 of the corresponding side end plates 111. As the winding column 120 drives the air conditioning component 200 to move, the relative opening layout of the guide grooves 131 can ensure that the filter screen is subject to cooperative constraints from both sides when it travels along the unwinding direction. This makes it difficult for the air conditioning component 200 to deviate or twist during movement. In other words, the opposite guide grooves 131 on the two end plates 111 enhance the synchronous control capability of the positions of the two ends of the air conditioning component 200, avoiding the problem of uneven force caused by unilateral guidance.

[0057] Specifically, in this embodiment, the end plate 111 includes a first mounting portion 1111 and a second mounting portion 1112. The first mounting portion 1111 is used to mount two winding posts 120, that is, both the take-up post 122 and the unwind post 121 are mounted on the first mounting portion 1111. These two winding posts 120 respectively perform the functions of winding and unwinding the air conditioning component 200; while the second mounting portion 1112 is used to mount or guide the unfolded air conditioning component 200 itself.

[0058] The outer periphery of the entire end plate 111 forms a complete circle. That is, the sum of the central angle corresponding to the outer arc of the first mounting portion 1111 and the central angle corresponding to the outer arc of the second mounting portion 1112 is 360°. Therefore, the arc segments corresponding to the outer periphery of the first mounting portion 1111 and the arc segments corresponding to the outer periphery of the second mounting portion 1112 together form a circle, and the sum of their corresponding central angles is 360°, indicating that these two parts are spatially complementary and located on the same annular structure. It is worth noting that the central angle range occupied by the first mounting portion 1111 is less than one-third of the central angle corresponding to the second mounting portion 1112. In other words, the second mounting portion 1112 occupies a larger proportion of the arc length on the annular end plate 111 to maximize the contact between the air conditioning component 200 and the airflow, achieving a better air conditioning effect.

[0059] It can be understood that in this embodiment, by setting the first mounting part 1111, which carries the winding column 122 and the unwinding column 121, to a smaller angle range, and configuring the second mounting part 1112, which is mainly used for the installation and guidance of the air conditioning component 200, to a larger angle range, it is possible to ensure that the unfolded air conditioning component 200 has a larger area, thereby improving the filtration effect of the air conditioning component 200.

[0060] In detail, after part of the air conditioning component 200 is wound on the unwinding column 121, the other end of the air conditioning component 200 extends along the extension direction of the second part away from the winding column 122 and is connected to the winding column 122. Furthermore, the two ends of the air conditioning component 200 in the axial direction of the winding column 120 are respectively disposed in the guide grooves 131 of the two end plates 111, thereby ensuring the stability of the movement of the air conditioning component 200 during the unwinding process.

[0061] Of course, in other embodiments, the guide portion 130 may also include other structures. For example, the guide portion 130 may include a plurality of guide rollers, the two ends of which are respectively disposed on two end plates 111 and the plurality of guide rollers are spaced apart along the circumferential direction of the second portion.

[0062] In this embodiment, to improve the filtration effect of the filter assembly 1, the filter assembly 1 further includes a filter element 300. A mounting cavity 140 is also provided within the mounting housing 110 for mounting the filter element 300, which is located inside the air conditioning component 200. It can be understood that the filter element 300 is located downstream of the airflow in the air conditioning component 200. That is, the airflow passes through the air conditioning component 200 before flowing through the filter element 300.

[0063] In detail, the inner peripheral wall of the second mounting part 1112 is also provided with a protruding strip 1114. The protruding strip 1114 and the outer peripheral wall of the guide groove 131 are arranged at a radial distance along the end plate 111 and together define the mounting cavity 140 extending in the extension direction of the second mounting part 1112.

[0064] The outer peripheral wall of the guide groove 131 and the protrusion 1114 are radially spaced. It should be noted that the outer peripheral wall of the guide groove 131 refers to the groove wall facing the outer edge of the end plate 111, while the protrusion 1114 is located on the relatively inner side. The two are not continuous structures but are radially separate. Thus, the protrusion 1114 and the outer peripheral wall of the guide groove 131 together define a spatial region extending along the extension direction of the second mounting portion 1112, which is the mounting cavity 140. In other words, this embodiment forms a mounting cavity 140 between the protrusion 1114 and the outer peripheral wall of the guide groove 131, which can be used to accommodate and position the filter element 300, allowing the filter element 300 to be fixed within this cavity and located inside the air conditioning component 200.

[0065] The end plate 111 simultaneously guides the winding motion and supports the air conditioning component 200 and the filter component 300, enabling the integrated installation of the multi-stage filter assembly 1 without the need for additional independent components. This improves the overall compactness and ease of assembly of the air conditioning component unwinding unit 100. For example, when the air purification device is running, external air is first initially intercepted by the unfolded air conditioning component 200, and then passes through the inner filter component 300 for deep purification.

[0066] Please refer to Figures 4-6 Optionally, in some embodiments, the end plate 111 has a rectangular plate structure, that is, the filter assembly 1 as a whole is a plate-shaped filter structure.

[0067] Two winding columns 120 are spaced apart at both ends of the end plate 111 along its length. In other words, the unwinding column 121 and the winding column 122 are spaced apart at both ends of the end plate 111 along its length. This ensures that the air conditioning component 200 between the unwinding column 121 and the winding column 122 has sufficient space to expand for filtration, thus improving the filtration efficiency of the filter assembly 1.

[0068] In detail, in this embodiment, a guide portion 130 is also provided between the two end plates 111. The two ends of the guide portion 130 are respectively connected to the two end plates 111 and located between the two winding posts 120. That is, the guide portion 130 is located between the winding post 122 and the unwinding post 121. The outer wall of the guide portion 130 is used to guide the air conditioning component 200 to move along the unwinding direction on the mounting housing 110. The guide portion 130 has a mounting cavity 140 for mounting the filter component 300. The mounting cavity 140 has two opposing openings. The orientation of the openings, the circumferential direction of the winding post 120, and the arrangement direction of the two winding posts 120 are perpendicular to each other.

[0069] With this configuration, the guide section 130 can not only guide the air conditioning component 200, but also has its own mounting cavity 140 to install the filter component 300 without occupying additional external space.

[0070] Optionally, in some embodiments, the unwinding unit of the air conditioning component further includes a mating mesh (not shown in the figure). The mating mesh is installed on the mounting housing 110 and located between the air conditioning component 200 and the filter 300. The mating mesh can also guide the air conditioning component 200 to facilitate its sliding and prevent excessive friction between the air conditioning component 200 and the filter 300, which could lead to poor sliding of the air conditioning component 200 or it getting stuck in the filter 300 and unable to slide.

[0071] Optionally, in some embodiments, at least one end of the winding post 120 is provided with a mating part 123, which can drive the winding post 120 to rotate under the action of external force. Specifically, the end plate 111 is provided with an opening 1113, and one end of the winding post 120 is provided with a mating part 123, which is exposed in the opening 1113. The mating part 123 can drive the winding post 120 to rotate under the action of external force.

[0072] One end of the winding post 120 extends to the location of the opening 1113, and a mating part 123 is provided at that end. The mating part 123 may be a convex ring, polygonal boss, keyway, spline, threaded structure, or other shape that can engage with an external operating tool (such as a wrench, drive rod, or motor output shaft) connected to the end of the winding post 120. Since the mating part 123 is exposed to the opening 1113, that is, at least partially extended or exposed to the outside of the end plate 111, it can be directly contacted and acted upon by externally applied operating forces without disassembling the overall structure.

[0073] During this process, when an external force is applied to the mating part 123 through a suitable tool, the external force is converted into a rotational torque and transmitted to the winding column 120 fixedly connected to it, thereby driving the winding column 120 to rotate relative to the mounting shell 110 around its own axis. As the winding column 120 rotates, the air conditioning element 200 wound on its surface can be gradually wound up or released, thereby achieving effective unfolding or recycling of the filter screen.

[0074] It can be understood that, by providing an opening 1113 on the end plate 111 and exposing the mating part 123 of the winding column 120 to the opening 1113, this embodiment allows users or automated equipment to directly intervene and control the rotation behavior of the winding column 120 from the outside, without having to perform complex disassembly of the unwinding unit 100 of the entire air conditioning component or rely on an additional transmission mechanism.

[0075] Alternatively, in some embodiments, such as Figures 1-4 As shown, the mating part 123 can be a protruding ring, which can rotate relative to the end of the winding post 120. When the mating part 123 is pulled upward, it acts like a handle, allowing the user to manually rotate the protruding ring to make the winding post 120 rotate around its own axis. After rotation, the user can rotate and retract the mating part 123 into the opening 1113. In this way, the mating part 123 of the protruding ring will not occupy too much volume, improving ease of use and adaptability.

[0076] Optionally, the air conditioning component 200 can be made of non-woven fabric or air conditioning mesh. Non-woven fabric, as a non-woven material, is formed by oriented or random fiber arrangement and reinforcement through mechanical, thermal bonding, or chemical methods. It has advantages such as controllable pore structure, low production cost, and ease of processing into rolls, making it suitable as the base material for the rollable air conditioning component 200. When the air conditioning component 200 is made of non-woven fabric, it can achieve continuous operation for a relatively long time while ensuring a certain filtration accuracy, and works in conjunction with the winding column 120 in the unwinding unit 100 of the air conditioning component to complete the unwinding and rewinding actions.

[0077] Filter mesh typically possesses high air permeability and a certain degree of dust resistance. It is mostly woven or welded from polyester, nylon, or other synthetic fibers, exhibiting good structural stability and durability. When used as an air conditioning component, air conditioning mesh offers advantages in applications requiring high airflow but with relatively relaxed requirements for fine particulate matter filtration.

[0078] In other words, whether the air conditioning component 200 is made of non-woven fabric or a filter mesh, it can be connected to the winding post 120 in the unwinding unit 100 of the air conditioning component, and under its drive, it can unfold or retract along the mounting shell 110, thereby realizing the function of dynamically replacing the filter area. Both materials have a balance of flexibility and strength suitable for the winding structure, and can maintain structural integrity during repeated bending.

[0079] Of course, in some embodiments, the air conditioning component 200 may also be made of PET filter, filter cotton, activated carbon cloth or moisture-absorbing paper, as long as it can adsorb dirt in the air. The material of the air conditioning component 200 is limited here.

[0080] In detail, to further improve the air conditioning component 200's ability to adsorb dirt, in some embodiments, the air conditioning component 200 can also be made of electrostatically charged cotton. Of course, in some other embodiments, the aforementioned air conditioning mesh or non-woven fabric can be charged with static electricity through an externally applied electrostatic structure, thereby improving the air conditioning component 200's ability to adsorb dirt.

[0081] Optionally, the filter element 300 is a pleated filter screen with a certain thickness. The filter element 300 serves as an independent filter medium housed within the mounting housing 110. The "pleated" structure refers to the periodic undulating pleated shape of the filter element 300 along its length when unfolded, resembling alternating peaks and valleys. This structure significantly increases the effective filtration area of ​​the filter element 300 compared to a planar filter screen, thereby achieving higher particulate matter capture efficiency within the same space. Simultaneously, the corrugated structure provides the filter screen with structural rigidity, allowing it to maintain a stable three-dimensional shape without additional support, reducing the risk of collapse during airflow and ensuring smooth ventilation.

[0082] This embodiment can be understood as follows: by setting the filter element 300 as a pleated filter screen, the filtration area and structural strength per unit space are increased without increasing the overall volume of the filter assembly 1. In other words, by improving the shape of the filter element 300 itself, both filtration capacity and mechanical stability can be enhanced.

[0083] Therefore, during the operation of the air purification device, the external dust-laden airflow passes through the air conditioning component 200 and the filter component 300 located inside it in sequence. The corrugated filter component 300, due to its large contact surface area, can more efficiently intercept fine particles and extend its overall service life.

[0084] In summary, this utility model embodiment provides an unwinding unit 100 for an air conditioning component, a filter assembly 1, and an air purification device. The air purification device includes the unwinding unit 100 for the air conditioning component, and the filter assembly 1 includes the unwinding unit 100 for the air conditioning component. The unwinding unit 100 for the air conditioning component includes a mounting shell 110 and a winding column 120. The winding column 120 is mounted on the mounting shell 110 and can rotate relative to the mounting shell 110 around its own axis. The winding column 120 winds the air conditioning component 200, and the air conditioning component 200 can drive the winding column 120 to rotate. The user can drive the mating part 123 and the unwinding column 121 to pull the air conditioning component 200 so that the clean air conditioning component 200 wound on the unwinding column 121 can be extended. The extended air conditioning component 200 will perform air conditioning functions such as adsorption of hair, dander, and dust. After a certain period of use, the user can drive the mating part 123 and the winding column 122 to wind up the air conditioning component 200 covered with the above-mentioned stains (i.e., the used air conditioning component 200). At this time, the unused air conditioning component 200 will be released from the unwinding column 121 and unfolded. This process is repeated so that the unused air conditioning component 200 can be unfolded and the air conditioning component 200 covered with the above-mentioned stains can be wound up. After all unused air conditioning components 200 have been used up, the user can remove them for replacement or disassemble the entire unwinding unit for replacement and maintenance. This allows for the replacement of both the clean air conditioning component 200 and the used filter, improving the efficiency of replacing the clean air conditioning component 200. This also facilitates filter replacement, avoids secondary contamination during filter replacement, and improves both the efficiency and user experience. The above description is merely a specific embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this utility model should be included within the scope of protection of this utility model.
