Description

Technical Field

[0001] This application relates to the field of air purification technology, and more particularly to an air purification device. Background Technology

[0002] Current air purifiers generally suffer from a fixed airflow direction design limitation. This results in a single airflow direction, making it impossible to flexibly adjust according to the specific layout of the indoor space and the distribution of people. This design flaw makes it difficult for air purifiers to achieve comprehensive and uniform purification of indoor air. Especially in large or complex indoor environments, air purifiers with a fixed airflow direction often fail to effectively deliver purified air to the required areas, leading to significant differences in air purification effects across different areas and uneven purification. Furthermore, in certain specific areas, such as densely populated areas or near pollution sources, the inability of air purifiers to adjust the airflow direction often results in low purification efficiency in localized areas, affecting the overall air purification effect and indoor air quality. Summary of the Invention

[0003] In view of the above-mentioned technical problems existing in the current technology, this application provides an air purification device.

[0004] This application provides an air purification device, which includes a fan assembly and a multi-stage series-connected air guide device. The fan assembly provides power for the circulation of purified gas. The multi-stage series-connected air guide device is located at the air outlet of the fan assembly and includes multiple air guide components connected in sequence. Each air guide component has an inclined end face connected to its adjacent air guide component. An actuating component is provided at the inclined end face, which is used to tilt and rotate at least one of the adjacent air guide components along the inclined end face, thereby rotatably switching the air outlet direction of the multi-stage series-connected air guide device between at least two of the following: a vertical air outlet direction, an inclined air outlet direction, and a horizontal air outlet direction. The above structure achieves flexible and adjustable air outlet direction for the multi-stage series-connected air guide device. By changing the air outlet direction, purified air can be effectively delivered to the required location, thereby achieving comprehensive and uniform purification of indoor air. It has a high purification efficiency and uniform effect, meeting the needs of different usage scenarios.

[0005] In some embodiments, the air purification device further includes a rotating base, on which the fan assembly and the multi-stage series air guide device are both mounted. The rotating base is used to rotatably adjust the air outlet direction of the multi-stage series air guide device in both inclined and horizontal air outlet directions to form a vector air delivery mode. Thus, by mounting the fan assembly and the multi-stage series air guide device together on a rotatable rotating base, the air outlet direction can be dynamically adjusted. Especially in inclined and horizontal air outlet directions, air can be evenly distributed to all sides of the air purification device, effectively improving the uniformity and targeting of the air outlet.

[0006] In some embodiments, the air guide assembly located at the air outlet of the fan assembly is a lower air guide assembly. The lower air guide assembly has a hollow lower airflow channel, and is used to guide the gas discharged from the fan assembly upward through the lower airflow channel. Thus, by guiding the gas discharged from the fan assembly upward within the hollow lower airflow channel, a vertical basis is provided for further vector adjustment of the subsequent multi-stage series air guide device.

[0007] In some embodiments, the air guide component furthest from the fan component among the plurality of air guide components is the upper air guide component. The upper air guide component has an internal air guide shell, which is constructed in a conical shape, with the tip of the conical structure positioned away from the fan component. Thus, the design of the internal conical air guide shell can create efficient airflow rectification and acceleration at the end of a multi-stage series air guide device, achieving directional airflow management, reducing duct resistance and airflow noise. When gas flows through the air guide shell, it can effectively reduce turbulence and vortex losses, smoothly converging and accelerating the airflow outwards.

[0008] In some embodiments, the multi-stage series air guiding device includes a lower air guiding component, a middle air guiding component, and an upper air guiding component connected in sequence. The lower air guiding component is located at the air outlet of the fan assembly. There is at least one middle air guiding component, and the included angle between the upper and lower inclined end faces of the middle air guiding component ranges from 30 degrees to 60 degrees. Thus, through the step-by-step connection and coordinated operation of the lower, middle, and upper air guiding components, precise and multi-dimensional adjustment of the airflow direction is achieved. The lower air guiding component is responsible for initially guiding the airflow upwards.

[0009] In some embodiments, the upper end face of the lower air guide assembly is constructed as the inclined end face, and the lower end face of the lower air guide assembly is horizontally arranged. The included angle between the upper and lower end faces of the lower air guide assembly ranges from 15 degrees to 40 degrees. Thus, the lower air guide assembly achieves the initial, controllable upward flow of air from the fan assembly, laying a crucial vertical foundation. The included angle range between the upper and lower end faces of the lower air guide assembly ensures that the air outlet direction of the multi-stage series air guide device can be reasonably adjusted after the middle air guide assembly rotates relative to the lower air guide assembly.

[0010] In some embodiments, the lower end face of the upper air guide component is constructed as the inclined end face, and the upper end face of the upper air guide component is horizontally arranged, with the included angle between the upper and lower end faces of the upper air guide component ranging from 15 degrees to 40 degrees. Thus, the structural design of the upper air guide component achieves adjustment and shaping of the final airflow attitude delivered by the upper-level air guide component, playing a rectifying and accelerating role, and ensuring the stability and concentration of the airflow at the end.

[0011] In some embodiments, one of the adjacent air guide components is provided with a positioning groove, and the other is provided with a positioning post inserted into the positioning groove, thereby limiting the rotation angle of the adjacent air guide components. In this way, the rotation range of adjacent air guide components is physically limited by the cooperation of the positioning groove and the positioning post, preventing angular deviation due to vibration or airflow impact during operation, ensuring the stability of the rotation angle of each stage of the air guide components, and thus guaranteeing the accuracy and consistency of the final air outlet direction, thereby improving the precision of the air supply coverage.

[0012] In some embodiments, the actuation component includes a drive member and a transmission component connected together. The drive member is disposed on an upper-level air guide component in an adjacent air guide component, and the transmission component is connected to a lower-level air guide component in an adjacent air guide component. The drive member is used to drive the lower-level air guide component to tilt and rotate relative to the upper-level air guide component through the transmission component. In this way, multiple levels of air guides can be driven by the drive member, and the transmission method of the transmission component is simple, stable, and direct, providing precise angle adjustment.

[0013] In some embodiments, the air purification device further includes a filter assembly disposed between the fan assembly and the rotating base, for filtering the gas entering the fan assembly. Thus, by distributing the filter assembly between the fan assembly and the rotating base, the airflow entering the fan is filtered, effectively improving the cleanliness of the air entering the system. This achieves pre-interception of particulate matter, some gaseous pollutants, or large molecules before the fan assembly's inlet, significantly reducing the burden on subsequent purification tasks and achieving highly efficient filtration or purification.

[0014] Compared with the current technology, the beneficial effects of the embodiments of this application are as follows: This application sets up a multi-stage series air guide device with multiple sequentially connected air guide components, and each of the air guide components has an inclined end face connected to the adjacent air guide component. The actuation component set on the inclined end face can make the air guide component tilt and rotate along the inclined end face, thereby realizing that the air outlet direction of the multi-stage series air guide device can be switched between at least two of the vertical air outlet direction, the inclined air outlet direction and the horizontal air outlet direction. That is, the air outlet direction of the multi-stage series air guide device is flexibly adjustable. By changing the air outlet direction, the purified air can be effectively delivered to the required place, thereby achieving comprehensive and uniform purification of indoor air, with high purification efficiency and uniform effect, meeting the needs of different scenarios.

[0029] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] This application provides an air purification device. For example... Figures 1 to 8 As shown, the air purification equipment includes a fan assembly 1 and a multi-stage series air guide device 2. The fan assembly 1 provides power for the circulation of purified gas. The multi-stage series air guide device 2 is located at the air outlet of the fan assembly 1. The multi-stage series air guide device 2 includes multiple air guide components 21 connected in sequence. Each air guide component 21 has an inclined end face 22 connected to the adjacent air guide component 21. An actuating component 3 is provided at the inclined end face 22. The actuating component 3 is used to tilt and rotate at least one of the adjacent air guide components 21 along the inclined end face 22, so as to rotatably switch the air outlet direction of the multi-stage series air guide device 2 between at least two of the vertical air outlet direction, the inclined air outlet direction, and the horizontal air outlet direction.

[0031] like Figures 3 to 8 As shown, Figure 3 and Figure 4The multi-stage series air guide device 2 shown in the figure has a vertical air outlet direction. Figure 5 and Figure 6 The multi-stage series air guide device 2 shown in the figure has an inclined air outlet direction. Figure 7 and Figure 8 The multi-stage series air guide device 2 shown in the figure has a horizontal air outlet direction. After at least one of the adjacent air guide components 21 is tilted and rotated along the inclined end face 22, it can switch between at least two of the above three air outlet directions.

[0032] The aforementioned fan assembly 1 may include at least a motor and an impeller (such as a centrifugal impeller or an axial flow impeller). The function of the fan assembly 1 is to drive the impeller to rotate at high speed through the motor, thereby creating negative pressure for air intake and positive pressure for air delivery within the equipment, thus providing power for the circulation of purified gas and pushing the air to the multi-stage series air guide device 2 for directional delivery.

[0033] The upper part of the aforementioned fan assembly 1 has a guide rib 11, which is used to actively guide the airflow to achieve the purpose of increasing efficiency, reducing noise and stabilizing the flow.

[0034] The multi-stage series-connected air guiding device 2 described above can be understood as not a single air guiding component 21, but rather including two or more air guiding components 24. The series connection means that the airflow must flow sequentially through each air guiding component 21, with the inlet of the next stage air guiding component 21 being the outlet of the previous stage air guiding component 21. The aforementioned air guiding component 21 can be a baffle plate, a flow straightener, a guide vane, a diffuser / constrictor tube, a guide cone, a guide shroud, etc. Specifically, such as... Figure 4 As shown, multiple air guide components 21 can be combined to form a barrel-shaped structure. Each air guide component 21 can include an outermost air guide shroud. Each air guide shroud can be provided with an inner shell 29. The gap between the inner shell 29 and the air guide shroud forms a hollow airflow channel, such as the lower airflow channel in the following text.

[0035] Bearing assemblies 6 can be installed between adjacent air guide assemblies 21, such as between the lower air guide assembly 23 and the middle air guide assembly 26, or between the middle air guide assembly 26 and the upper air guide assembly 24, to reduce the rotational friction of adjacent air guide assemblies 21 and facilitate the smooth rotation of the air guide assemblies 21. The bearing assemblies 6 can be arranged circumferentially around the edge of the air guide assembly 21 to minimize the friction of the air guide assembly 21.

[0036] After the aforementioned fan assembly 1 and multi-stage series air guide device 2 are installed, they can form a barrel-shaped structure, and the outer surfaces of the two are smoothly connected, making the overall appearance of the equipment elegant and simple. The barrel-shaped structure can minimize the space occupied by the air purification equipment.

[0037] The multiple air guiding components 21 of the above-mentioned multi-stage series air guiding device 2 can cooperate to form a continuous streamlined air duct. The streamlined air duct has the characteristics of low wind resistance, low noise and high air outlet efficiency.

[0038] The middle parts of adjacent air guide components 21 can be connected by a connecting shaft, so that the air guide component 21 can tilt and rotate around the axis of the connecting shaft and the plane where the inclined end face 22 is located. After tilting and rotating, the air outlet direction of the air guide component 21 will change, thereby realizing the adjustment of the air outlet direction of the air guide component 21.

[0039] This application sets up a multi-stage series air guide device 2 with multiple sequentially connected air guide components 21, and each air guide component 21 has an inclined end face 22 connected to its adjacent air guide component 21. The actuation component 3 set on the inclined end face 22 can make the air guide component 21 tilt and rotate along the inclined end face 22, so that the air outlet direction of the multi-stage series air guide device 2 can be switched between at least two of the vertical air outlet direction, the inclined air outlet direction and the horizontal air outlet direction. That is, the air outlet direction of the multi-stage series air guide device 2 is flexibly adjustable. By changing the air outlet direction, the purified air can be effectively delivered to the required place, thereby achieving comprehensive and uniform purification of indoor air, with high purification efficiency and uniform effect, meeting the needs of different scenarios.

[0040] In some embodiments, such as Figures 1 to 8 As shown, the air purification equipment also includes a rotating base 4, a fan assembly 1 and a multi-stage series air guide device 2, all of which are mounted on the rotating base 4. The rotating base 4 is used to rotatably adjust the air outlet direction of the multi-stage series air guide device 2 in the inclined air outlet direction and the horizontal air outlet direction to form a vector air supply mode.

[0041] Thus, by mounting the fan assembly 1 and the multi-stage series air guide device 2 together on the rotatable rotating base 4, the airflow direction can be dynamically adjusted. Especially in the inclined airflow direction and the horizontal airflow direction, the air can be evenly distributed to all sides of the air purification equipment, which effectively improves the uniformity and targeting of the airflow of the air purification equipment and helps to optimize energy utilization efficiency.

[0042] The aforementioned rotating seat 4 may include at least a seat body and a rotating motor, the rotating motor being used to drive the seat body to rotate the fan assembly 1 and the multi-stage series air guide device 2.

[0043] The aforementioned vector air supply mode can be understood as a mode in which the air outlet direction changes. Under the tilted air outlet direction and the horizontal air outlet direction, as the rotating seat 4 rotates, the air outlet direction of the multi-stage series air guide device 2 will blow evenly to all sides of the device, covering a comprehensive range. This allows the air outlet direction to change, rather than always blowing air in one direction, which is beneficial to improving air purification efficiency and user experience, and meeting the needs of different usage scenarios.

[0044] In some embodiments, the rotating base 4 may remain stationary when the air outlet direction of the multi-stage series air guide device 2 is perpendicular to the air outlet direction. In this case, the air purification equipment maintains a vertically upward blowing mode, i.e., a vertical air supply mode. In the vertical air supply mode, multiple air guide components 21 are coaxially vertical, the air duct is straight, and the airflow is delivered vertically upward, suitable for rapid purification with a high-volume airflow. It is understood that under the same operating parameters of the fan assembly 1, the air volume in the vertical air supply mode is greater than that in the vector air supply mode. This is because the air outlet angle is different, resulting in different flow resistance; the air volume will decrease in the vector air supply mode.

[0045] In some embodiments, such as Figures 1 to 8 and Figure 11 As shown, the air guide component 21 located at the air outlet of the fan assembly 1 is a lower air guide component 23. The lower air guide component 23 has a hollow lower airflow channel, and the lower air guide component 23 is used to guide the gas discharged from the fan assembly 1 upward through the lower airflow channel.

[0046] Thus, by guiding the gas discharged from the fan assembly 1 upward through the hollow lower airflow channel, a vertical basis is provided for further vector adjustment of the subsequent multi-stage series air guide device 2.

[0047] The aforementioned lower air guide component 23 can be used to guide the gas discharged from the fan component 1 to blow vertically upward, reducing airflow impact and facilitating smooth airflow transition.

[0048] In some embodiments, such as Figures 1 to 9 As shown, among the multiple air guide components 21, the air guide component 21 that is furthest from the fan component 1 is the upper air guide component 24. The upper air guide component 24 has an air guide shell 25 inside. The air guide shell 25 is constructed as a conical structure, and the tip of the conical structure is set away from the fan component 1.

[0049] Thus, the design of the internal conical air guide shell 25 can form efficient airflow rectification and acceleration at the end of the multi-stage series air guide device 2, realize the directional sorting of airflow, reduce airflow resistance and airflow noise. When the gas flows through the air guide shell 25, it can effectively reduce turbulence and vortex loss, smoothly gather the airflow and accelerate its exit, thereby ensuring that the gas is discharged in a more concentrated and stable form.

[0050] The aforementioned air guide shell 25 covers at least part of the actuator 3 on the side near its upper-level air guide assembly 21, making the airflow more reasonable and preventing the airflow from blowing towards the actuator 3 and affecting the operation of the actuator 3.

[0051] In some embodiments, such as Figures 1 to 12 As shown, the multi-stage series air guiding device 2 includes a lower air guiding component 23, a middle air guiding component 26, and an upper air guiding component 24 connected in sequence. The lower air guiding component 23 is located at the air outlet of the fan component 1. There is at least one middle air guiding component 26, and the included angle between the upper and lower inclined end faces 22 of the middle air guiding component 26 is between 30 degrees and 60 degrees. Figure 3 As shown, Figure 3 Angle A shown in the figure is the included angle between the upper and lower inclined end faces 22 of the middle air guide assembly 26.

[0052] In this way, through the step-by-step connection and coordinated operation of the lower air guide component 23, the middle air guide component 26 and the upper air guide component 24, the airflow direction can be finely and multidimensionally adjusted. The lower air guide component 23 is responsible for the initial upward airflow guidance, at least one middle air guide component 26 can adjust the airflow deflection multiple times as needed, so as to gradually adjust and optimize the airflow direction, and the upper air guide component 24 can further adjust the direction of the air outlet, which effectively improves the adaptability of the air purification equipment to complex indoor environments and can significantly improve the uniformity of air quality.

[0053] The lower air guide assembly 23 and the upper air guide assembly 24 can each have one end face that is an inclined slope, that is, the end face used to connect with the middle air guide assembly 26 is an inclined end face 22. The middle air guide assembly 26 can have both its upper and lower end faces as inclined end faces 22.

[0054] Preferably, the included angle between the upper and lower inclined end faces 22 of the central air guide assembly 26 can be 35°, 40°, 45°, 50° or 55°.

[0055] At least one of the aforementioned lower air guide assembly 23, middle air guide assembly 26, and upper air guide assembly 24 can be rotated to change the air outlet direction of the multi-stage series air guide device 2. Specifically, the middle air guide assembly 26 can drive the upper air guide assembly 24 to rotate relative to the lower air guide assembly 23, thereby achieving an inclined air outlet direction; the upper air guide assembly 24 can rotate relative to the middle air guide assembly 26 and the lower air guide assembly 23, thereby achieving a horizontal air outlet direction.

[0056] For example, such as Figure 4 and Figure 5 As shown, the middle air guide assembly 26 can drive the upper air guide assembly 24 to rotate 180° relative to the lower air guide assembly 23, so as to switch the air outlet direction of the multi-stage series air guide device 2 from the vertical air outlet direction to the inclined air outlet direction. Figure 5 and Figure 7As shown, the upper air guide assembly 24 can rotate 180° relative to the middle air guide assembly 26 and the lower air guide assembly 23 to switch the air outlet direction of the multi-stage series air guide device 2 from the inclined air outlet direction to the horizontal air outlet direction.

[0057] In some embodiments, such as Figure 3 and Figure 4 As shown, the upper end face of the lower air guide assembly 23 is constructed as an inclined end face 22, and the lower end face of the lower air guide assembly 23 is horizontally arranged. The included angle between the upper and lower end faces of the lower air guide assembly 23 ranges from 15 degrees to 40 degrees. Figure 3 As shown, Figure 3 Angle B shown in the figure is the included angle between the upper and lower end faces of the lower air guide assembly 23.

[0058] Thus, the lower air guide assembly 23 achieves the first controllable upward flow of the air outlet direction of the fan assembly 1, laying a key vertical foundation. The included angle range between the upper and lower end faces of the lower air guide assembly 23 can ensure that the middle air guide assembly 26 can reasonably adjust the air outlet direction of the multi-stage series air guide device 2 after rotating relative to the lower air guide assembly 23.

[0059] Preferably, the included angle between the upper and lower end faces of the lower air guide assembly 23 can be 17°, 20°, 23°, 26°, 29°, 32°, 35° or 38°.

[0060] In some embodiments, such as Figure 3 and Figure 4 As shown, the lower end face of the upper air guide assembly 24 is constructed as an inclined end face 22, and the upper end face of the upper air guide assembly 24 is horizontally set. The included angle between the upper and lower end faces of the upper air guide assembly 24 ranges from 15 degrees to 40 degrees. Figure 3 As shown, Figure 3 Angle C shown in the figure is the included angle between the upper and lower end faces of the upper air guide assembly 24.

[0061] Thus, the structural design of the upper air guide component 24 enables the adjustment and shaping of the final airflow from the upper air guide component, thereby playing a role in rectification and acceleration, and ensuring the stability and concentration of the airflow at the end.

[0062] Preferably, the included angle between the upper and lower end faces of the lower air guide assembly 23 can be 17°, 20°, 23°, 26°, 29°, 32°, 35° or 38°.

[0063] In some embodiments, such as Figures 9 to 11 As shown, one of the adjacent air guide components 21 is provided with a positioning groove 27, and the other is provided with a positioning post 28 inserted into the positioning groove 27, so as to limit the rotation angle of the adjacent air guide components 21.

[0064] In this way, the rotation range of adjacent air guide components 21 can be physically limited by the cooperation of the positioning groove 27 and the positioning column 28, preventing the angle deviation caused by vibration or airflow impact during operation, ensuring the stability of the rotation angle of each level of air guide components 21, thereby ensuring the accuracy and consistency of the final air outlet direction, and thus improving the precision of air supply coverage.

[0065] Specifically, the lower-level air guide component in the adjacent air guide component 21 can be provided with a positioning column 28, and the upper-level air guide component in the adjacent air guide component 21 can be provided with a positioning slot 27. The upper-level air guide component and the lower-level air guide component are defined according to the gas flow direction. The lower air guide component 23 is the upper-level air guide component of the middle air guide component 26, the middle air guide component 26 is the upper-level air guide component of the upper air guide component 24, the middle air guide component 26 is the lower-level air guide component of the lower air guide component 23, and the upper air guide component 24 is the lower-level air guide component of the middle air guide component 26.

[0066] For example, such as Figures 9 to 12 As shown, a positioning post 28 can be provided on the side of the upper air guide assembly 24 facing the middle air guide assembly 26, and a positioning groove 27 adapted to the positioning post 28 can be provided on the side of the middle air guide assembly 26 facing the upper air guide assembly 24; a positioning post 28 can be provided on the side of the middle air guide assembly 26 facing the lower air guide assembly 23, and a positioning groove 27 adapted to the positioning post 28 can be provided on the side of the lower air guide assembly 23 facing the middle air guide assembly 26.

[0067] The aforementioned positioning groove 27 can be specifically arc-shaped, U-shaped, etc. This application does not make specific limitations on it, as long as it can limit the rotation of the air guide component 21 to rotate within a certain range, and prevent it from rotating 360° circumferentially.

[0068] In some embodiments, such as Figure 4 and Figures 9 to 12 As shown, the actuation component 3 includes a drive component 31 and a transmission component 32 connected to each other. The drive component 31 is disposed on the upper-level air guide component in the adjacent air guide component 21, and the transmission component 32 is connected to the lower-level air guide component in the adjacent air guide component 21. The drive component 31 is used to drive the lower-level air guide component to tilt and rotate relative to the upper-level air guide component through the transmission component 32.

[0069] In this way, the multi-stage air guide can be driven by the drive component 31, and the transmission method of the transmission component 32 is simple, stable and direct, with precise angle adjustment.

[0070] It is understandable that an actuation component 3 is provided between adjacent air guide components 21. When there is only one lower air guide component 23, one middle air guide component 26 and one upper air guide component 24, there can be two actuation components 3, which are respectively provided between the lower air guide component 23 and the middle air guide component 26, and between the middle air guide component 26 and the upper air guide component 24.

[0071] The aforementioned transmission assembly 32 can be one or a combination of the following structures: a lead screw and nut structure, a worm gear structure, a gear transmission structure, and a belt transmission structure. For example, the transmission assembly 32 includes a meshing driving gear and a driven gear. The driving gear is connected to the driving member 31, and the driven gear is connected to the lower-level air guide assembly in the adjacent air guide assembly 21, so as to achieve stable rotation of the air guide assembly 21 through gear transmission.

[0072] In some embodiments, such as Figures 1 to 3 As shown, the air purification equipment also includes a filter assembly 5, which is located between the fan assembly 1 and the rotating base 4, and is used to filter the gas entering the fan assembly 1.

[0073] Thus, the filter component 5 is located between the fan component 1 and the rotating seat 4 to filter the airflow entering the fan, effectively improving the cleanliness of the air entering the system. This allows for the early interception of particulate matter, some gaseous pollutants, or large molecules at the inlet of the fan component 1, significantly reducing the burden of subsequent purification tasks and achieving the purpose of efficient filtration or purification.

[0074] The aforementioned filter component 5 can use a filter screen structure to achieve basic impurity interception and filtration. At the same time, it can be adapted to various structural forms such as multi-layer composite filter media, porous filter cartridges, and grid filters according to actual operating conditions. It can perform graded filtration of particles and impurities of different sizes, effectively improving filtration accuracy and overall purification effect, and adapting to different purification needs.

[0075] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its scope and spirit, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
