Description

Technical Field

[0001] This application relates to the field of purification technology, and in particular to a purifier and a multi-split air purification unit. Background Technology

[0002] In existing technologies, the air inlet and outlet of the purifier are located adjacent to each other on the same side. This causes the clean air discharged through the outlet to be repeatedly drawn back into the adjacent air inlet, resulting in ineffective circulation purification, wasting energy, and greatly reducing purification efficiency. Summary of the Invention

[0003] The purpose of this application is to provide an air purifier and a multi-split air purifier unit, which aims to solve the problems of ineffective circulation purification and low energy efficiency of traditional air purifiers.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides a purifier, including:

[0006] The housing has an air duct and an air inlet and an air outlet connected to the air duct. The air inlet and the air outlet are at the same horizontal height, and the plane of the air inlet is perpendicular to the plane of the air outlet.

[0007] A filter element is disposed in the air duct and is used to filter the objects to be cleaned that enter through the air inlet;

[0008] A fan is installed inside the air duct and located between the filter component and the air outlet.

[0009] The air purifier provided in this application, by designing the air inlet and outlet to be perpendicular to each other and located at the same horizontal level, effectively avoids the problem of short airflow paths caused by the proximity of the air outlet and inlet in traditional designs. After passing through the filter components, air is discharged from the outlet. Because the air outlet and inlet planes are perpendicular, the discharged clean air is not directly re-inhaled, avoiding repeated filtration of clean air, thus reducing ineffective circulation, improving overall purification efficiency, and reducing unnecessary energy consumption. Furthermore, placing the air inlet and outlet at the same horizontal level and adopting a vertical layout helps to reduce the overall size of the purifier, making it more suitable for placement in various small indoor spaces, increasing the product's applicability and market competitiveness. This is an important feature for users with limited living space.

[0010] Optionally, the housing includes:

[0011] Base;

[0012] The main body is mounted on the base. The main body is provided with the air duct, the air inlet and the air outlet, and the main body can swing horizontally and / or pitch relative to the base.

[0013] The air purifier provided in this application, by swinging its main body horizontally (left and right) and tilting it up and down on the base, can deliver clean air to every corner of the room, not just the area in front of the purifier, thus ensuring a balanced improvement in the overall quality of indoor air.

[0014] Optionally, the filter component is provided with a filter channel, and the end of the filter channel is provided with an air inlet that is connected to the air inlet. The sidewall of the filter channel is connected to the air duct.

[0015] The air purifier provided in this application, by placing the air inlet at the end of the filter channel, can more effectively guide particulate matter (such as hair, dust, etc.) directly into the interior of the filter channel. Since the air first enters the filter through the end air inlet when flowing within the filter channel, and then enters the air duct from the side wall of the filter channel, this design results in a longer path and a larger contact area for the air as it passes through the filter material. This facilitates a more thorough removal of particulate matter and harmful substances from the air, improving filtration efficiency.

[0016] Optionally, the filter element includes:

[0017] The primary filter assembly is provided with the aforementioned filter channel;

[0018] HEPA filter paper is fitted over the pre-filter assembly.

[0019] The air purifier provided in this application further enhances its filtration efficiency by combining a multi-layer filtration structure of a pre-filter assembly and HEPA filter paper.

[0020] Optionally, the primary filter assembly includes:

[0021] The frame is detachably connected to the air inlet of the housing;

[0022] A pre-filter is connected to the frame and has the filter channel; the HEPA filter paper is sleeved outside the pre-filter.

[0023] The air purifier provided in this application features a detachable frame design, allowing users to easily remove the pre-filter assembly for cleaning or replacement. In particular, for large particulate pollutants accumulated on the pre-filter, such as hair and dust, they can be directly rinsed with water or cleaned with a vacuum cleaner, further improving the maintenance convenience and service life of the air purifier.

[0024] This application also provides a multi-split air purification unit, including: the above-mentioned purifier, wherein the number of the purifiers is multiple;

[0025] The air purifiers are arranged around the edge of the area to be cleaned, and the air inlets and outlets of the air purifiers are alternately and cyclically connected along the circumferential direction.

[0026] The air outlets of each of the purifiers can swing horizontally in the same direction in sequence according to the ring cloth order;

[0027] Alternatively, the air outlet of the purifier can be tilted up and down.

[0028] The multi-split air purifier unit provided in this application achieves a pet hair removal mode by having its purifiers arranged in a ring and swinging horizontally in the same direction. This mode simulates an orderly airflow guidance mechanism, systematically pushing hair from the floor to the air inlet of the next purifier, thus achieving continuous and directional hair collection and purification. This orderly airflow management avoids the pollution problem caused by turbulent airflow and flying hair, improving hair removal efficiency. While centrally processing floor hair, each purifier also continuously filters particulate matter in the air, ensuring that indoor air quality is comprehensively improved while removing hair, meeting the special air quality needs of pet-owning families.

[0029] When switched to air purification mode, the purifier's air outlet can tilt and oscillate, allowing clean air to reach the top, bottom, and center of the room, achieving a three-dimensional purification effect from floor to ceiling. Compared to a fixed air outlet, this mode can distribute clean air more quickly and evenly, accelerating the overall circulation and purification of indoor air.

[0030] Optionally, the number of the purifiers is two;

[0031] The two air purifiers are positioned diagonally across the area to be cleaned;

[0032] Alternatively, two of the purifiers may be positioned on opposite sides of the area to be cleaned.

[0033] The multi-split air purification unit provided in this application further optimizes the air purification effect by arranging two units diagonally or on opposite sides. It can provide matching solutions according to actual space conditions and purification needs, effectively improving the flexibility and efficiency of multi-split air purification unit design.

[0034] Optionally, the area to be cleaned is quadrilateral in shape, and the number of purifiers is four;

[0035] The four air purifiers are respectively placed at the four corners of the area to be cleaned;

[0036] Alternatively, the four purifiers may be respectively placed on the four sides of the area to be cleaned.

[0037] The multi-split air purification unit provided in this application, by adopting a layout strategy of four purifiers, can significantly enhance the overall performance of air purification, improve the uniformity of air quality in the space, and increase the overall purification efficiency, regardless of whether the four corners or four sides are arranged.

[0038] Optionally, when the air outlet of the purifier swings horizontally, the air outlet is set horizontally.

[0039] The multi-split air purifier unit provided in this application, when the purifier's air outlet is horizontally oscillating in hair removal mode, sets the air outlet horizontally. This avoids the problem of hair being scattered due to the airflow blowing directly downwards, and also overcomes the limitation of the air outlet being unable to effectively target hair when it is pointing upwards. The horizontal airflow can more accurately push hair along the ground, ensuring that it is successfully captured by the next purifier, thereby effectively improving the efficiency of hair collection and purification.

[0040] Optionally, when the air outlet of the purifier tilts, the tilt angle of the air outlet is between 30° and 60°.

[0041] The multi-split air purifier unit provided in this application, when operating in air purification mode with its air outlet tilting upwards at an angle of 30° to 60°, causes the purified air to rise in a spiral shape, forming a three-dimensional air circulation within the room. This circulation mode is more effective than simple horizontal or vertical airflow in covering the entire room space, including high places and corners, ensuring that every area is exposed to fresh, clean air, achieving truly three-dimensional, no-dead-angle purification.

[0063] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0064] In the description of the embodiments of this application, it should be understood that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0065] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0066] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0067] According to an embodiment of the first aspect of this application, referring to... Figures 1-7 As shown, this application provides an air purifier 100, mainly including: a housing 101, a filter element 102, and a fan 103. The housing 101 has an internal air duct, and also has an air inlet and an air outlet 1011 connected to the air duct. The air inlet and air outlet 1011 are at the same horizontal level, and the plane of the air inlet is perpendicular to the plane of the air outlet 1011. The filter element 102 is disposed within the air duct and is used to filter the substances to be cleaned entering through the air inlet. The fan 103 is disposed within the air duct and located between the filter element 102 and the air outlet 1011.

[0068] In this embodiment of the application, by designing the air inlet and outlet 1011 to be perpendicular to each other and located at the same horizontal level, this layout effectively avoids the problem of short airflow paths caused by the proximity of the air outlet and air inlet in traditional designs, meaning that the purified air will not be immediately re-inhaled. After passing through the filter element 102, the air is discharged from the outlet 1011. Since the outlet 1011 is perpendicular to the plane of the air inlet, the discharged clean air will not be directly re-inhaled, thereby reducing ineffective circulation, ensuring the purification effect, and reducing unnecessary energy consumption.

[0069] Placing the air inlet and outlet 1011 at the same horizontal level and using a vertical layout helps to reduce the overall size of the air purifier 100, making it more suitable for placement in various small indoor spaces, increasing the product's applicability and market competitiveness. This is an important feature for users with limited living space.

[0070] In addition to functional improvements, this design also contributes to a simple and aesthetically pleasing appearance. The vertically symmetrical layout makes it easy to integrate into different interior decoration styles, thereby enhancing the user experience.

[0071] The filter element 102 is located inside the air duct and directly processes the air to be cleaned entering from the air inlet. This direct and continuous filtration process reduces airflow resistance and improves purification efficiency. The filter element 102 is designed to effectively intercept particles of different sizes, from large dust and hair particles to micron-sized bacteria and viruses, achieving comprehensive purification.

[0072] The fan 103 is placed between the filter element 102 and the air outlet 1011. This arrangement ensures that the clean air passing through the filter element 102 can be effectively pushed to the air outlet 1011 and then quickly distributed into the indoor space.

[0073] Therefore, the embodiments of this application effectively solve the problems of low efficiency and energy waste in traditional air purifiers through a unique airflow guidance design, while taking into account the practicality, energy saving, miniaturization and aesthetics of the product.

[0074] According to one embodiment of this application, refer to Figure 1 and Figure 2 As shown, the housing 101 mainly includes components such as a base 1012 and a main body 1013. The main body 1013 is disposed on the base 1012, and the main body 1013 is provided with an air duct, an air inlet and an air outlet 1011, and the main body 1013 can swing horizontally and / or pitch relative to the base 1012.

[0075] In this embodiment of the application, by the horizontal swing (left-right swaying) and pitch swing (up-down swaying) of the main body 1013 on the base 1012, the purifier 100 can deliver clean air to every corner of the room, not just the area in front of the purifier 100. This design is particularly suitable for scenarios requiring comprehensive air purification, such as living rooms and bedrooms, ensuring a balanced improvement in the overall quality of indoor air.

[0076] Traditional stationary air purifiers often only effectively purify the air around or directly in front of them, with limited effectiveness against pollutants at the far ends or higher up in the room. This application, through its oscillating function, achieves whole-house purification without requiring users to frequently move the purifier, significantly improving purification efficiency and spatial coverage.

[0077] Furthermore, the flexible design, adaptable to diverse indoor environments, allows the Air Purifier 100 to accommodate varying furniture layouts in different rooms. Whether in a spacious hallway or a compact small room, users can adjust the Air Purifier 100's oscillation mode and angle to ensure optimal purification results. This personalized control enhances ease of use and user satisfaction. For example, when rapid purification of the entire room is needed, the full-angle oscillation mode can be activated, simultaneously oscillating horizontally and vertically; when focused purification is required in a specific area, the angle can be adjusted to the most suitable setting.

[0078] Therefore, by adding horizontal and vertical swing functions to the main body 1013 on the base 1012, this embodiment of the application not only greatly expands the effective working range of the purifier 100, but also improves the user experience and purification efficiency.

[0079] According to one embodiment of this application, refer to Figures 1-4 As shown, the main body 1013 is roughly T-shaped and includes: a first main body 1014 and a second main body 1015. The first main body 1014 is provided with a first air duct 1016 and an air inlet. A filter component 102 is disposed in the first air duct 1016, and the air inlet is connected to the end of the first air duct 1016. The second main body 1015 is perpendicular to the first main body 1014 and is provided with a second air duct 1017 that communicates with the first air duct 1016. An air outlet 1011 is disposed at the end of the second air duct 1017 away from the first air duct 1016, and a fan 103 is disposed in the second air duct 1017.

[0080] In this embodiment of the application, by designing the main body 1013 as a T-shaped structure, efficient separation and integration of functional areas are achieved. The first main body 1014 focuses on the introduction and preliminary treatment of air, while the second main body 1015 focuses on the final purified output of air. This layout optimizes the air duct design within a limited space, allowing the purifier 100 to be more compact and adaptable to a wider range of installation environments.

[0081] Air enters through the air inlet of the first main body 1014, undergoes preliminary purification through the filter element 102 in the first air duct 1016, and then turns to enter the second air duct 1017 of the second main body 1015. Here, driven by the fan 103, it is discharged from the air outlet 1011. This arrangement ensures a smoother airflow path, reduces airflow backflow and loss, and improves purification efficiency.

[0082] It is worth mentioning that separating the air inlet and outlet 1011 using a T-shaped structure effectively avoids the risk of purified air being re-inhaled, reduces ineffective circulation, improves purification efficiency, and reduces unnecessary energy consumption. Furthermore, the T-shaped structure also provides a clear physical separation between the filter element 102 and the outlet 1011, helping to reduce the mixing of purified and unpurified air and ensuring the purity of the output air.

[0083] Furthermore, the T-shaped design of the 100 air purifier makes it suitable for placement in any corner of the home, saving space while providing highly efficient purification. In open spaces such as shopping malls and restaurants, multiple T-shaped 100 air purifiers can be flexibly arranged to form a networked multi-unit air purification system, meeting the air purification needs of large spaces.

[0084] According to one embodiment of this application, refer to Figure 2 and Figure 4 As shown, the air purifier 100 of this application also includes a pitch drive mechanism, which mainly includes components such as a connecting seat 104, a first gear 105, a second gear 106, and a motor 107. The connecting seat 104 is disposed on a base and has a support portion 1041 adapted to the first main body 1014. The first main body 1014 is rotatably connected to the support portion 1041 of the connecting seat 104. The first gear 105 is disposed at the other end of the first main body 1014 away from the air inlet. The motor 107 is mounted on the end face of the support portion 1041 of the connecting seat 104 and is disposed on the same side as the first gear 105. The shaft of the motor 107 is connected to the second gear 106, and the second gear 106 meshes with the first gear 105.

[0085] In this embodiment of the application, when pitching is required, the motor 107 drives the second gear 106 to rotate, which in turn drives the first gear 105 to rotate, thereby causing the first main body 1014 to rotate on the support portion 1041 of the connecting seat 104, achieving up-and-down oscillation, i.e., pitching. The maximum rotation angle of the oscillation can be 90° or other angles. This design allows the air purifier 100 to dynamically adjust the direction of the air outlet 1011 according to user needs or indoor layout, effectively expanding the purification range, and is especially suitable for high ceilings or occasions where purification of spaces at different heights is required.

[0086] Furthermore, the precise control capability of the motor 107 allows the first main body 1014 to rotate to the desired fixed angle position. Users can flexibly adjust the air outlet angle of the purifier 100 according to the actual structure and pollution level of the room, achieving refined purification of the indoor space and improving purification efficiency and coverage.

[0087] In addition, users can easily adjust the tilt angle of the purifier 100 through the control panel or remote control, and realize customized air purification services according to seasonal changes, different indoor activity areas, or to meet temporary purification needs, thereby improving the product's interactivity and user satisfaction.

[0088] According to one embodiment of this application, the connecting seat 104 can rotate left and right on the base 1012, thereby causing the entire main body of the purifier 100 to swing horizontally. For example, the connecting seat 104 can be rotated by a drive motor on the base 1012, and the maximum rotation angle can be 90° or other angles. The user can control the drive motor to make the main body rotate to the desired fixed angle position according to actual needs.

[0089] Specifically, combined with the tilting and oscillating function of the aforementioned embodiment, the purifier 100 can achieve omnidirectional movement, including swaying left and right as well as up and down. This design allows the purified air to be more evenly distributed to every corner of the room, effectively purifying even the edges and hard-to-reach areas, achieving true whole-house purification without dead angles.

[0090] According to one embodiment of this application, refer to Figure 4 As shown, the first gear 105 is a ring gear with the teeth of the ring gear located on the inner ring, and the second gear 106 is located on the inner side of the ring gear.

[0091] Specifically, the inner ring gear tooth design makes the entire drive mechanism more compact. In particular, the second gear 106 is located inside the ring gear. This layout effectively reduces the space occupied by the purifier 100, which helps to make the overall design of the purifier 100 more compact and miniaturized, making it easier to install and use in small spaces.

[0092] The inner ring gear design allows for tighter gear meshing, reducing backlash during transmission. This ensures that when the motor 107 drives the second gear 106, it can more smoothly and precisely drive the first gear 105. This design helps reduce noise, improves the quietness of the purifier's operation, and enhances the user experience.

[0093] By optimizing the meshing method and position of the gears, the transmission efficiency can be improved and the energy loss reduced, so that the driving force of the motor 107 can be more effectively converted into the smooth rotation of the main body 1013 of the purifier 100, thereby ensuring the purification effect while saving energy.

[0094] According to one embodiment of this application, refer to Figures 2-4 As shown, the pitch drive mechanism of this application also includes a protective cover 108. The protective cover 108 is disposed on the end face of the support portion 1041 of the connecting seat 104. The protective cover 108 can cover the motor 107, or it can cover the motor 107 and the gear structure. The specific design can be adjusted according to actual needs.

[0095] Specifically, the protective cover 108 can effectively shield the motor 107, gears and other structures, preventing users from accidentally coming into contact with the high-speed rotating motor 107 and gears when operating or cleaning the purifier 100, reducing the risk of electric shock and mechanical injury, and conforming to the basic principles of electrical equipment safety design.

[0096] In daily use, dust, pet hair, and other foreign objects floating in the air may enter the purifier 100, affecting the normal operation of the motor 107 and gears. The protective cover 108 can block these foreign substances, reduce the frequency of internal cleaning, and extend the service life of the device.

[0097] The protective cover 108 can also play a certain role in sound insulation, reducing the transmission of noise generated by the motor 107 during operation, improving the user experience, especially when used at night, it can create a quieter environment.

[0098] In addition, a rotating shaft can be installed inside the protective cover 108. The center of the other end of the first main body 1014 away from the air inlet is provided with a connecting hole 1018 that is rotatably connected to the rotating shaft, and the annular first gear 105 is concentrically arranged with the connecting hole 1018, thereby ensuring the stable rotation of the purifier 100.

[0099] According to one embodiment of this application, refer to Figure 1 and Figure 3 As shown, the filter component 102 is provided with a filter channel 1021, and the end of the filter channel 1021 is provided with an air inlet 1022 that is connected to the air inlet. The side wall of the filter channel 1021 is connected to the air duct, which is the first air duct 1016 of the first main body 1014.

[0100] In this embodiment of the application, by placing the air inlet 1022 at the end of the filter channel 1021, particulate matter (such as hair, dust, etc.) can be more effectively guided directly into the interior of the filter channel 1021. Since air first enters the filter through the end air inlet 1022 when flowing within the filter channel 1021, and then enters the first air duct 1016 from the side wall of the filter channel 1021, this design results in a longer path and a larger contact area for the air as it passes through the filter material. This facilitates more thorough removal of particulate matter and harmful substances from the air, improving filtration efficiency.

[0101] The design of air entering from the end of the filter channel 1021 and exiting from the side wall can distribute the airflow more evenly, reduce local high-pressure areas on the filter material, thereby reducing the resistance when air passes through the filter component 102, reducing the noise generated by the fan 103, and improving the user experience.

[0102] Therefore, by changing the way air enters the filter element 102, this embodiment of the application not only improves the ability to capture large particulate pollutants, but also optimizes the filtration efficiency and reduces operating noise.

[0103] According to one embodiment of this application, refer to Figures 5-7 As shown, the filter component 102 includes a pre-filter assembly and a HEPA filter paper 1023. The pre-filter assembly is provided with a filter channel 1021; the HEPA filter paper 1023 is sleeved on the outside of the pre-filter assembly.

[0104] In this embodiment of the application, the pre-filter assembly serves as the first line of defense, primarily responsible for intercepting large particles in the air, such as dust, hair, and pet dander. This not only reduces the burden on subsequent filter layers but also extends the service life of fine filter layers such as the HEPA filter paper 1023. Following this, the HEPA filter paper 1023 is specifically designed to capture tiny particles, such as viruses, bacteria, and pollen, achieving highly efficient particulate filtration.

[0105] The pre-filter assembly, as a pre-filtration layer, can effectively block large particulate pollutants, preventing these substances from clogging the HEPA filter paper 1023, thereby protecting the expensive HEPA filter paper 1023, reducing its replacement frequency, and lowering maintenance costs.

[0106] The multi-stage filtration design helps maintain unobstructed airflow because the pre-filter assembly removes most of the larger particles, reducing the risk of clogging the HEPA filter 1023. This allows air to pass more smoothly through the HEPA filter 1023, ensuring high-efficiency purification performance while maintaining low air resistance and reducing energy consumption.

[0107] Therefore, the embodiments of this application further enhance the filtration accuracy and efficiency of the purifier 100 by combining the multi-layer filtration structure of the pre-filter assembly and the HEPA filter paper 1023.

[0108] According to one embodiment of this application, refer to Figure 7 As shown, the filter component 102 also includes an activated carbon layer 1024, which is sleeved on the outside of the HEPA filter paper 1023.

[0109] In this embodiment of the application, air first passes through a pre-filter assembly to filter large particles, and then through a HEPA filter paper 1023 for fine filtration, effectively removing fine particles such as viruses, bacteria, and dust mites. Subsequently, the purified air flows through an outer activated carbon layer 1024, which focuses on adsorbing harmful gases, odors (such as smoke and formaldehyde), and volatile organic compounds (VOCs) in the air. This design ensures that particulate matter is removed first, followed by deep purification of chemical pollutants, resulting in a more thorough purification effect.

[0110] Therefore, by combining a multi-layer filtration structure of a pre-filter assembly, HEPA filter paper 1023, and activated carbon layer 1024, this application can achieve a layered and efficient purification effect, significantly improving air quality.

[0111] According to one embodiment of this application, refer to Figures 5-7 As shown, the pre-filter assembly includes a frame 1025 and a pre-filter 1026. The frame 1025 is detachably connected to the air inlet of the housing 101. The pre-filter 1026 is connected to the frame 1025 and has a filter channel 1021. A HEPA filter paper 1023 is fitted over the pre-filter 1026. The pre-filter 1026 can be a cylindrical filter, or other types of filters, depending on the specific design requirements.

[0112] In this embodiment of the application, the detachable design of the frame 1025 allows users to easily remove the pre-filter assembly for cleaning or replacement. This is especially convenient for large particulate contaminants such as hair and dust accumulated on the pre-filter 1026, which can be directly rinsed with water or cleaned with a vacuum cleaner. Furthermore, regular cleaning or replacement of the pre-filter 1026 effectively prevents large particles from entering the subsequent HEPA filter paper 1023, reducing clogging and contamination of the HEPA filter paper 1023, thereby extending its service life and reducing maintenance costs.

[0113] According to one embodiment of this application, refer to Figures 5-7As shown, the frame 1025 includes a bracket, a first end cap 10251, a second end cap 10252, and a handle 10253. The first end cap 10251 and the second end cap 10252 are connected by several circumferentially spaced brackets. The primary filter 1026 is wrapped around the brackets to form a filter channel 1021. The edge of the second end cap 10252 has multiple circumferentially spaced buckles 10254. The edge of the air inlet of the housing 101 has a locking seat that engages with the buckles 10254, thereby enabling quick assembly and disassembly of the primary filter assembly. The second end cap 10252 also has an air inlet 1022 corresponding to and communicating with the air inlet for easy air intake. The inner wall of the second end cap 10252 also has a stepped portion 10255, and the handle 10253 is rotatably connected to the stepped portion 10255 of the second end cap 10252.

[0114] When there is no need to disassemble or install the primary filter assembly, the handle 10253 can be hidden inside the second end cover 10252. When it is necessary to disassemble or install the primary filter assembly, simply turn the handle 10253 to pull the primary filter assembly outward from the end of the housing 101. It is convenient and quick to use.

[0115] In one example, since a large amount of visible hair, particulate matter, etc. will be concentrated on the pre-filter 1026, in order to avoid frequent disassembly of the HEPA filter paper 1023 and the activated carbon layer 1024, the second end cap 10252 can be integrally injection molded with the pre-filter 1026. The HEPA filter paper 1023 and the activated carbon layer 1024 can be installed in the first main body 1014 of the housing 101 through the frame structure 1027, so as to achieve separate installation from the pre-filter assembly.

[0116] Of course, the HEPA filter paper 1023 and activated carbon layer 1024 can also be directly wrapped around the outer wall of the pre-filter 1026. Alternatively, the frame structure 1027 can be connected to the first end cap 10251 or the second end cap 10252 to achieve integrated installation of the entire filter component 102, facilitating cleaning and maintenance of the entire filter component 102. The specific installation method of the filter component 102 can be adjusted and designed according to actual needs.

[0117] According to one embodiment of this application, the air purifier 100 further includes a plasma component, which is disposed in the second air duct 1017 of the second main body 1015. The plasma component may include a plasma generator and a plasma emitter. The plasma generated by the plasma generator is sent to the second air duct 1017 through the plasma emitter. The plasma can be quickly dispersed into the room by the fan 103 along with the clean airflow, avoiding damage to the internal components of the equipment due to the accumulation of plasma forming high pressure.

[0118] The plasma component in this embodiment combines the aforementioned left-right and up-down oscillation modes, enabling the plasma to quickly reach any location indoors, kill bacteria, viruses, and other allergens, and simultaneously purify every corner of the room quickly and thoroughly, achieving comprehensive purification.

[0119] The multi-split air purification unit provided in this application will be described below. The purifier 100 of the multi-split air purification unit described below can be compared with the purifier 100 described above.

[0120] According to an embodiment of the second aspect of this application, referring to... Figure 8 As shown, this application also provides a multi-split air purification unit, mainly including: an air purifier 100 of any of the above embodiments, wherein there are multiple air purifiers 100; wherein each air purifier 100 is arranged around the edge of the area to be cleaned 200, and the air inlet and air outlet 1011 of each air purifier 100 are sequentially and alternately connected along the circumferential direction, that is, the air outlet of the first air purifier is connected to the air inlet of the second air purifier, the air outlet of the second air purifier is connected to the air inlet of the third air purifier, and so on, so that the air inlet and outlet of all air purifiers are alternately circulated.

[0121] The air outlets 1011 of each air purifier 100 can swing horizontally in the same direction in sequence. That is, when the first air purifier swings horizontally, the other air purifiers do not swing, allowing the hair on the ground to be blown to the second air purifier for purification. After the first air purifier finishes swinging, the second air purifier swings horizontally while the other air purifiers do not swing, allowing the hair on the ground to be blown to the third air purifier for purification. After the second air purifier finishes swinging, the third air purifier swings horizontally while the other air purifiers do not swing, allowing the hair on the ground to be blown to the fourth air purifier for purification, and so on, until all air purifiers complete the hair removal mode in a clockwise or counterclockwise direction in sequence.

[0122] Alternatively, the air outlet 1011 of the purifier 100 can tilt and oscillate to achieve an air purification mode. It is understandable that air purification can also be achieved when the purifier 100 is not oscillating.

[0123] In this embodiment of the application, the collaborative operation of multiple air purifiers 100 not only solves the problem of low efficiency of a single air purifier 100 in large spaces or specific scenarios, but also provides a flexible solution for different purification needs. Specifically:

[0124] By having the air purifiers 100 arranged in a ring and swinging horizontally in the same direction, a hair removal mode can be achieved. This mode simulates an orderly airflow guidance mechanism, systematically pushing hair from the floor towards the air inlet of the next purifier 100, thus achieving continuous and directional hair collection and purification. This orderly airflow management avoids the pollution problem caused by turbulent airflow and flying hair, improving hair removal efficiency. While centrally processing floor hair, each purifier 100 also continuously filters particulate matter in the air, ensuring that indoor air quality is comprehensively improved while removing hair, meeting the special air quality needs of pet-owning families. It is particularly suitable for pet-owning families or spaces where floor clutter easily accumulates, effectively addressing the purification needs during specific periods such as seasonal pet shedding.

[0125] When switched to air purification mode, the air outlet 1011 of the purifier 100 can tilt and oscillate, allowing clean air to cover the top, bottom, and center of the room, achieving a three-dimensional purification effect from floor to ceiling. Compared to a fixed air outlet, this mode can distribute clean air more quickly and evenly, accelerating the overall circulation and purification of indoor air. This mode can respond rapidly to changes in indoor air quality, especially when rapid air purification is needed or when dealing with sudden pollution events, quickly improving indoor air quality through all-around airflow coverage.

[0126] Therefore, the multi-split air purifier unit in this application embodiment not only creatively solves the air purification problem in specific scenarios such as pet-filled households through intelligent multi-unit collaborative operation, but also demonstrates high flexibility and adaptability, and can switch freely between different purification needs, greatly improving purification efficiency and user experience.

[0127] According to one embodiment of this application, refer to Figure 8 As shown, there are two air purifiers 100; the two air purifiers 100 are arranged diagonally on the opposite side of the area to be cleaned 200; or, the two air purifiers 100 are arranged on opposite sides of the area to be cleaned 200.

[0128] Specifically, the shape of the area to be cleaned 200 can be square, or it can be oval, circular, trapezoidal or irregular polygonal.

[0129] One of the two air purifiers 100 can act as a host to control both air purifiers 100, or the user terminal can issue control commands to control both air purifiers 100.

[0130] When two air purifiers 100 are placed diagonally opposite each other in the area to be cleaned 200, the first air purifier can be controlled to swing left and right 45° while the second air purifier remains stationary, allowing the hair on the ground to be blown to the air inlet of the second air purifier for absorption and filtration. After the first air purifier finishes swinging, the second air purifier swings left and right 45° while the first air purifier remains stationary, allowing the hair on the ground to be blown to the air inlet of the first air purifier for absorption and filtration, thereby achieving continuous and directional hair purification.

[0131] When two air purifiers 100 are placed on opposite sides of the area to be cleaned 200, the first air purifier can be controlled to swing left and right 90° while the second air purifier remains stationary, allowing the hair on the ground to be blown to the air inlet of the second air purifier for absorption and filtration. After the first air purifier finishes swinging, the second air purifier swings left and right 90° while the first air purifier remains stationary, allowing the hair on the ground to be blown to the air inlet of the first air purifier for absorption and filtration, thereby achieving continuous and directional hair purification.

[0132] This application embodiment utilizes a dual-unit diagonal arrangement or a layout strategy on opposite sides to further optimize the air purification effect through the collaborative operation of the two units. It can provide a matching solution according to actual space conditions and purification needs, effectively improving the flexibility and efficiency of multi-unit air purification unit design.

[0133] According to another embodiment of this application, the area to be cleaned 200 is quadrilateral in shape, and the number of air purifiers 100 is four; the four air purifiers 100 are respectively disposed at the four corners of the area to be cleaned 200; or, the four air purifiers 100 are respectively disposed on the four sides of the area to be cleaned 200.

[0134] Specifically, the shape of the area to be cleaned 200 can be square, rhomboid, or an irregular quadrilateral. The working process of four machines set at the four corners or four sides of the area to be cleaned 200 is similar to the working process of two machines set at opposite corners or two sides of the area to be cleaned 200, and will not be described in detail here.

[0135] This application embodiment adopts a layout strategy of four air purifiers 100. Whether the four corners or the four sides are arranged, the overall performance of air purification can be significantly enhanced, and the uniformity of air quality in the space and the overall purification efficiency can be improved.

[0136] According to one embodiment of this application, when the air outlet 1011 of the purifier 100 swings horizontally, the air outlet 1011 is set horizontally.

[0137] In this embodiment of the application, when the air outlet 1011 of the purifier 100 is horizontally oscillating in the hair removal mode, setting the air outlet 1011 horizontally avoids the problem of hair scattering caused by the airflow blowing directly downwards onto the ground. It also overcomes the limitation that the air outlet 1011 cannot effectively target hair when it is upwards. The horizontal airflow can more precisely push hair along the ground, ensuring it is successfully captured by the next purifier 100, thereby effectively improving the efficiency of hair collection and purification.

[0138] Furthermore, the horizontal airflow design is more in line with the principles of fluid mechanics, and can generate a stable airflow band. This airflow pattern is more efficient in moving hair in a designated direction and is less likely to cause air turbulence, reducing the resuspension of indoor dust and particles that may occur during the purification process, and maintaining the cleanliness of indoor air.

[0139] When multiple air purifiers 100 work together, the horizontally positioned air outlets 1011 of each air purifier 100 form a continuous and orderly airflow chain, ensuring that hair and other ground pollutants can be systematically guided to the next purification point. This synergistic effect greatly improves the overall purification efficiency, making it especially suitable for large-area or complex indoor environments.

[0140] According to one embodiment of this application, when the air outlet 1011 of the purifier 100 tilts, the tilt angle of the air outlet 1011 is between 30° and 60°. Preferably, the tilt angle of the air outlet 1011 can be 45°.

[0141] Specifically, when the air outlet 1011 of the purifier 100 is in air purification mode, all air outlets 1011 of the purifier 100 can be controlled to rotate upward at a 45° angle. Multiple units can simultaneously blow air clockwise or counterclockwise, which promotes the purified air to rise in a spiral shape, forming a three-dimensional air circulation in the room. This circulation mode can cover the entire room space more quickly and effectively than simple horizontal or vertical airflow, including high places and corners, ensuring that every area is exposed to fresh, clean air, achieving truly three-dimensional purification without dead angles.

[0142] By accelerating the airflow in the room, old air containing pollutants can be diluted and replaced more quickly. Especially in rooms with high ceilings or in enclosed spaces, this design can significantly improve air exchange efficiency, reduce the residence time of pollutants, and rapidly improve indoor air quality.

[0143] The elevation angle design of this application embodiment aims to maximize the air purification effect without increasing additional energy consumption. By optimizing the airflow path, the purified air can achieve the maximum coverage and purification efficiency with minimal energy consumption, making it both environmentally friendly and highly efficient.

[0144] According to one embodiment of this application, each air purifier 100 is equipped with a Bluetooth device, which can communicate with the air purifier 100 through user terminals such as remote control, mobile phone, and computer. The user can issue control commands to the air purifier 100 through the user terminal, thereby realizing coordinated operation of multiple devices.

[0145] The above are merely preferred embodiments of this application and are not intended to limit the embodiments of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
