Description

Technical Field

[0001] This invention belongs to the field of purification technology, and in particular relates to a purifier. Background Technology

[0002] As people's demands for indoor air quality continue to increase, air purifiers have become an indispensable household appliance in modern homes and offices. Traditional air purifiers typically use a single fan and single duct structure, with airflow mainly exiting from the front or top of the device in a single direction. This results in problems such as limited air delivery range, low air circulation efficiency, and the creation of purification dead zones. Especially in larger spaces, these products struggle to achieve rapid and uniform air purification, often requiring users to run the device for extended periods to achieve the desired effect.

[0003] To improve airflow and purification efficiency, some products attempt to enhance performance by increasing the size of the fan or the number of air ducts. However, this often leads to an increase in the size of the equipment, especially a significant increase in the horizontal projection area, which occupies more floor space and is particularly inconvenient in small apartments, corner placements, or compact usage scenarios. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a purifier that has a small footprint and a large air volume.

[0005] The objective of this invention can be achieved through the following technical solution: A purifier, comprising:

[0006] Multiple air outlet modules stacked vertically;

[0007] Each air outlet module includes at least one air outlet surface, wherein at least a portion of the air outlet surface forms a connected air outlet surface in the horizontal direction.

[0008] In one of the air purifiers described above, the rotation axis of the air outlet impeller in at least one of the air outlet modules is not parallel to the rotation axis of the air outlet impellers in the other air outlet modules.

[0009] The purifier described above also includes a mounting shell, which includes a mounting cavity, and multiple air outlet modules are disposed within the mounting cavity.

[0010] In one of the air purifiers described above, at least one partition is fixedly installed inside the mounting cavity to separate air outlet modules with different rotation axis directions of the air outlet impeller.

[0011] In one of the air purifiers described above, the air outlet module at the top emits air in a horizontal direction.

[0012] In the aforementioned air purifier, at least a portion of the air outlet impeller is provided with an air guide shroud. The air guide shroud includes a plurality of coaxial and spaced-apart air guide rings, and the diameter of the rings gradually changes as they are closer to the air outlet impeller, thereby guiding the air toward the air outlet impeller.

[0013] When the air guide ring is provided with a connecting part for connecting with the drive part of the air outlet impeller, the air guide ring exhibits a gradual change in diameter as it gets closer to the air outlet impeller in a straight line.

[0014] In one of the purifiers described above, there is also a mounting part. The mounting part is annular and coaxially arranged with the air guide ring. The mounting part is located outside the outermost air guide ring and there is a gap between them. The mounting part is used to connect with the purifier housing. When the air guide ring is provided with a connecting part for connecting with the drive part of the air outlet impeller, the outermost air guide ring protrudes from the mounting part along the axial direction of the air outlet impeller.

[0015] In the aforementioned purifier, a wiring section is further included. The wiring section extends from the mounting section to the innermost air guide ring. The extension direction of the wiring section is perpendicular to the axis of the air outlet impeller. The wiring section includes a wiring cavity with an opening on the windward surface. The bottom wall of the wiring cavity is provided with an air passage groove. The inner side wall of the wiring cavity is provided with wire-blocking posts at intervals.

[0016] In one of the air purifiers described above, a wire clamping cover is detachably installed on the wiring section of the mounting part.

[0017] In one of the above-mentioned air purifiers, a junction box fixed to the mounting part is also included. A junction box has a junction cavity, and a through-hole cable outlet is provided on the junction box and communicates with the junction cavity.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) The air purifier adopts a structure layout in which multiple air outlet modules are stacked vertically, which reduces the space occupied by the equipment in the horizontal direction and effectively reduces the space requirements of the product on the ground or the placement plane, making it especially suitable for compact indoor environments.

[0020] (2) Each air outlet module has at least one air outlet surface, and at least some of the air outlet modules form a continuous, surrounding horizontal air outlet area in the horizontal direction. This allows airflow to be evenly discharged from multiple sides of the purifier in the horizontal direction at the same time, achieving a wide-area air supply effect that diffuses in all directions, significantly improving air circulation efficiency, accelerating indoor air purification speed, and avoiding discomfort caused by excessively high local wind speeds.

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0034] like Figures 1-10 As shown, an air purifier includes:

[0035] Multiple air outlet modules 100 stacked vertically;

[0036] Each air outlet module 100 includes at least one air outlet surface 101, wherein at least a portion of the air outlet surface 101 forms a connected air outlet surface 101 in the horizontal direction.

[0037] The air purifier of the present invention adopts a structural layout in which multiple air outlet modules 100 are stacked vertically, reducing the space occupied by the device in the horizontal direction and effectively reducing the space requirements of the product on the ground or placement surface, making it especially suitable for compact indoor environments.

[0038] Each air outlet module 100 is provided with at least one air outlet surface 101, and at least some of the air outlet modules 100 have air outlet surfaces 101 forming a continuous, circumferential horizontal air outlet area in the horizontal direction. This allows airflow to be evenly discharged horizontally from multiple sides of the purifier simultaneously, achieving a wide-area air delivery effect that diffuses in all directions, significantly improving air circulation efficiency, accelerating indoor air purification, and avoiding discomfort caused by excessively high local wind speeds.

[0039] By increasing the number of air outlet modules 100, the overall air outlet area 101 and air volume can be flexibly expanded. This enhances the airflow output capacity of the purifier without increasing the bottom projection area, meeting the purification needs of spaces of different sizes and achieving modular performance expansion. Simultaneously, the multi-module stacked structure facilitates layered airflow design, enabling coordinated air delivery with a multi-fan system, further optimizing airflow organization and improving energy efficiency and quiet operation.

[0040] Furthermore, the rotation axis of the outlet impeller 107 in at least one outlet module 100 is not parallel to the rotation axis of the outlet impellers 107 in the other outlet modules 100. This forms a multi-directional airflow drive layout. This allows different outlet modules 100 to generate airflow movement in different directions, significantly enhancing the airflow disturbance capability and spatial coverage.

[0041] like Figure 2As shown, in one specific implementation, two air outlet modules 100 are provided. Both the upper and lower modules are axial air intake and radial air outlet, but the axial directions of the air outlet impellers in the two modules are perpendicular, thereby achieving multi-dimensional and three-dimensional airflow organization within a limited floor area.

[0042] In addition, by adjusting the air volume and operating status of different air outlet modules 100, dynamic control of airflow direction can be achieved to meet the personalized air supply needs of different usage scenarios and improve user comfort.

[0043] The air purifier of the present invention also includes a mounting shell 102, which has a mounting cavity inside, and multiple air outlet modules 100 stacked vertically are integrated into the mounting cavity. The mounting shell 102 provides a unified and enclosed mounting space for each air outlet module 100, and serves as structural support and external protection.

[0044] At least one partition 103 is fixedly installed inside the mounting cavity to separate the air outlet modules 100 with different rotation axes of the air outlet impeller 107. This forms independent airflow channels, avoiding mutual interference or uneven mixing of airflows from multiple directions within the mounting cavity. The partition 103 not only serves as an airflow isolation mechanism but also enhances the overall structural rigidity of the mounting cavity, preventing relative displacement or deformation between modules due to vibrations generated during fan operation. Especially under high wind speed and high power conditions, the additional support provided by the partition 103 effectively improves the overall vibration resistance and operational stability of the unit.

[0045] Furthermore, the air outlet module 100 located at the top disperses the air in a horizontal direction.

[0046] This design allows purified air to be horizontally distributed from the top of the equipment, significantly increasing the air outlet height and bringing it closer to the normal breathing zone of the human body. When placed vertically, this air outlet position avoids the indirect air supply path of traditional bottom-level or bottom-supply systems, which causes airflow to first blow towards the ground and then bounce upwards, effectively reducing energy loss and path detours during airflow delivery.

[0047] It should be noted that the mounting housing 102 is detachably equipped with an inspection cover 104, and the mounting cavity has an independent filter element installation area 105. Each air outlet module 100 is equipped with a filter element 106. Each filter element installation area 105 is connected to a plug-in port, supporting the direct insertion or removal of the filter element 106 in the horizontal direction. The filter element 106 can be replaced without disassembling the entire unit or moving the equipment, greatly improving the convenience of user maintenance and user experience. Furthermore, when the inspection cover 104 is fixed to the mounting housing 102, it can completely cover the plug-in port, effectively preventing dust and foreign objects from entering the internal air duct, ensuring airflow cleanliness and electrical safety. When it is necessary to replace the filter element 106 or perform internal inspection, the plug-in port can be exposed simply by removing the inspection cover 104, enabling quick maintenance and filter element 106 replacement.

[0048] In particular, the filter element 106 in the top air outlet module 100 is positioned below the air outlet impeller 107. This not only achieves the purification function but also raises the air outlet impeller 107, making the air outlet area of ​​the first air outlet module 100 closer to the height of the human body's normal breathing zone. Secondly, the filter element 106 is located between different air outlet modules 100, effectively isolating the airflow field of the air outlet impeller 107 in different air outlet modules 100, avoiding negative effects such as airflow backflow and vortex interference caused by the high-speed rotation of adjacent impellers.

[0049] like Figures 5-9 As shown, based on the above embodiment, at least part of the end of the air outlet impeller 107 is provided with an air guide shroud 200. The air guide shroud 200 includes a plurality of coaxial and spaced air guide rings 202, and the diameter of the rings 202 gradually changes as they are closer to the air outlet impeller 107, so as to guide the air toward the air outlet impeller 107.

[0050] When the air guide ring 202 is provided with a connecting part 202 for connecting with the drive part of the air outlet impeller 107, the air guide ring 202 exhibits a gradual change in diameter as it gets closer to the air outlet impeller 107 in a straight line.

[0051] The air guide shroud 200 in this application is used in an air purifier. By setting multiple coaxial and axially arranged air guide rings 202, a gradual flow channel structure is formed between the multiple air guide rings 202, which can effectively guide the airflow smoothly into the outlet impeller 107, significantly improving the uniformity and continuity of the intake airflow, and enhancing the overall air volume and energy efficiency. Moreover, it also achieves the organic integration of air guiding function and mechanical connection function. In particular, the connecting part 202 provided on the air guide shroud 200 makes the air guide shroud 200 itself also serve as a mounting support for the drive component. This eliminates the need for a separate bracket or additional fastening components for connecting the motor in traditional structures, improving the integration of the drive system and the air duct structure.

[0052] As the diameter of the air guide ring 202 gradually decreases as it gets closer to the air outlet impeller 107, the shrinkable structure provides the necessary space and structural adaptation conditions for setting the connecting part 202 for connecting the drive unit of the air outlet impeller 107 in the central area, thereby realizing the integration of the air guide shroud 200 and the drive component.

[0053] Conversely, as the diameter of the air guide ring 202 gradually increases as it approaches the outlet impeller 107, it forms an expanding air guide channel, which can effectively increase the air intake area, enhance the ability to capture the surrounding airflow, and improve the air guide range and air intake efficiency.

[0054] Each air guide ring 202 is fixed together by reinforcing sections spaced in an annular pattern. The ends of some of these reinforcing sections not only extend towards the innermost air guide ring 202 but also connect and are fixed to adjacent reinforcing sections. This transforms the multiple reinforcing sections from being independent entities into a continuous, collaboratively stressed support frame, significantly improving the overall integrity and rigidity of the internal structure of the air guide shroud 200. This enhances the air guide shroud 200's ability to bear central loads (such as mechanical stress during drive unit connection) and improves the structure's torsional, compressive, and vibration resistance.

[0055] Furthermore, the air guide cover 200 also includes a coaxially arranged annular mounting portion 203. This mounting portion 203 is located outside the outermost air guide ring 202 and maintains a certain gap with it, used to stably connect the air guide cover 200 to the purifier housing, achieving reliable fixation of the overall structure. The separate design avoids interference of the mounting portion 203 with the airflow channel of the air guide ring 202, which helps maintain the smoothness and guidance of the airflow.

[0056] Specifically, when the guide ring 202 is provided with a connecting portion 202 for connecting the drive unit of the outlet impeller 107, the outermost guide ring 202 protrudes from the mounting portion 203 along the axial direction of the outlet impeller 107. This protruding structure extends the axial length of the guide area, allowing the airflow to be guided and converged earlier when entering the guide shroud 200, effectively expanding the effective air intake range and enhancing the ability to capture surrounding air, thereby significantly improving the air guiding effect and the overall air intake volume.

[0057] An annular connecting ring 204 is provided inside the innermost air guide ring 202, and the outer ring wall of the connecting ring 204 is fixedly connected to the innermost air guide ring 202 by multiple connecting plates 205 evenly spaced along its circumference, forming a stable internal support structure. This enhances the structural rigidity and integrity of the central area of ​​the air guide shroud 200, effectively avoiding deformation or breakage caused by localized stress concentration, and maintaining structural stability, especially under high-speed airflow impact or long-term operation conditions.

[0058] Multiple connecting parts 202 are distributed in a ring at intervals between the connecting ring 204 and the air guide ring 202 (or directly integrated into the connecting ring 204), and the connecting parts 202 extend inward from the innermost air guide ring 202 or the connecting ring 204 along the axial direction of the outlet impeller 107, forming a connection structure that actively extends towards the interior of the purifier. This extended connecting part 202 can surround and cover the drive unit, realizing a coaxial and tight connection between the air guide shroud 200 and the drive system of the outlet impeller 107.

[0059] like Figure 5 , Figure 10 As shown, based on the above embodiment, it also includes a wiring section 300. The wiring section 300 extends from the mounting section to the innermost air guide ring 202. The extension direction of the wiring section 300 is perpendicular to the axis of the air outlet impeller 107, forming a radial wiring channel from the outside to the inside. This structure provides a dedicated guiding path for the wires or signal lines connected to the drive unit (such as a motor), realizing the orderly arrangement of cables inside the air guide cover 200, and avoiding the cables from being messy and tangled or vibrating, wearing or even breaking due to airflow impact.

[0060] Specifically, the wiring section 300 is constructed as a semi-enclosed wiring cavity 303, forming a protected internal channel for accommodating and guiding the connecting wires of the drive unit. The bottom wall of the wiring cavity 303 is provided with an air passage 302, which extends through the bottom of the wiring cavity 303 and communicates with the air inlet channel. When the air guide shroud 200 is in operation, external airflow can enter not only from the main flow channel between the air guide rings 202, but also flow into the interior through the air passage 302, effectively increasing the air inlet area and improving the overall airflow. Multiple wire-blocking posts 301 are spaced apart on the inner wall of the wiring cavity 303 to prevent the wire harness from slipping out during operation due to vibration, airflow impact, or assembly disturbance, ensuring the stability and safety of the electrical connection. Furthermore, the wire-blocking posts 301 are staggered along the extension direction of the cable routing cavity 303, that is, adjacent wire-blocking posts 301 are alternately arranged on the inner walls of both sides of the cable routing cavity 303, and only one end is fixed to the cavity wall, forming a cantilever structure.

[0061] A cable management section 305 is fixedly installed inside the cable routing cavity 303. The cable management section 305 is provided with a cable management groove 306 with an opening at one end. The connecting wire can be inserted from the opening end and locked into the cable management groove 306 to achieve the positioning and organization of the connecting wire. Furthermore, a cable clamping cover 304 is detachably provided on the cable routing section 300. When the cable clamping cover 304 is assembled to the cable routing section 300, it covers the opening of the cable routing cavity 303 and clamps and fixes the connecting wire located in the cable management groove 306, preventing the connecting wire from being displaced, rubbed, or detached due to vibration or external force during equipment operation.

[0062] Furthermore, the cable clamp cover 304 employs a detachable connection method (such as a snap-fit, screw, or magnetic structure), ensuring functionality while maintaining maintainability of the internal wiring of the cable routing cavity 303. Users or maintenance personnel can easily remove the cable clamp cover 304 when needed to inspect, replace, or re-lay out the cables, balancing pneumatic performance and engineering practicality.

[0063] It also includes a junction box 400 fixed to the mounting unit. The junction box 400 has a cable management cavity 401 inside, used to accommodate and organize redundant cable segments reserved during assembly of the connecting wires to the drive unit. During the assembly and subsequent maintenance of the air purifier, a certain length of slack is usually reserved at the cable end for easy installation, disassembly, or adjustment of the air guide shroud 200. The cable management cavity 401 provides dedicated storage space for these reserved cable segments, effectively preventing insulation damage, signal interruption, or short circuit risks caused by cable pressure, twisting, or friction. The junction box 400 has a through-hole cable outlet 405 connected to the cable management cavity 401, used to guide the connecting wire smoothly out of the cable management cavity 401 and into the purifier's main circuit system, or to connect the connecting wire to the drive unit.

[0064] The junction box 400 includes a box body 402 and a cover 403 detachably connected to the box body 402. A connecting post 404 is fixedly installed inside the box body 402. The connecting post 404 is used to cooperate with the cover 403 to achieve detachable fixation (such as through snap-fit, thread, or interference fit). On the other hand, it also has a structural reuse function, serving as a winding post in the cable collection cavity 401, allowing the connecting wires to be wound around it. It not only undertakes the mechanical connection function of the cover 403, ensuring the sealing and structural stability of the junction box 400, but also serves as a winding structure for cable storage, used to neatly wind and fix the reserved connecting wires, preventing the cables from loosely shaking, tangling, or being pulled by external forces in the cable collection cavity 401.

[0065] Once the cover 403 and the body 402 are assembled, they cover the cable outlet 405 and form a seal on the cable outlet 405, thereby effectively preventing external airflow from entering the equipment housing through the cable outlet 405.

[0066] Furthermore, it also includes an air duct plate 406, which serves as a common mounting base for the air guide shroud assembly and is used for fixed connection with the purifier housing. The mounting part of the air guide shroud and the junction box 400 are pre-fixed to the air duct plate 406, forming a modular unit that can be assembled as a whole. This simplifies the installation process of the air guide shroud, wiring system, and related components during the overall assembly of the purifier, improving assembly efficiency and positioning accuracy.

[0067] Specifically, when the air purifier is equipped with multiple air outlet impellers 107 (such as a dual-duct or multi-fan system), multiple air guide covers 200 can be installed, each with a corresponding mounting part, and all mounting parts are fixed to the same air duct plate 406. The overall positioning and fixing are completed by a single air duct plate 406, which greatly simplifies the assembly complexity of the multi-fan structure.
