Spliced multi-angle air purifier

Abstract

This invention relates to a modular multi-angle air purifier. A rotary transmission component drives a supporting horizontal plate to rotate around a central circular support base, causing the air purifier bodies on both sides to rotate synchronously, achieving 360° multi-directional airflow. Simultaneously, a lifting transmission component adjusts the height of the air outlet sleeve, forming a three-dimensional purification space and eliminating the limitations of traditional unidirectional airflow. Compared to traditional unidirectional airflow designs, this eliminates dead zones and significantly expands the effective purification range, making it particularly suitable for large spaces such as open-plan living rooms and offices. The power switching clutch component supports two operating modes depending on usage requirements: in the "rotation + lifting" synchronous mode, a single power source simultaneously drives rotation and lifting, reducing redundant energy consumption; in the independent lifting mode, energy consumption is reduced and component lifespan is extended. Furthermore, one or two air purifier bodies can be installed together, offering excellent practicality.

Description

Technical Field

[0001] This invention relates to the field of air purifier technology, and in particular to a modular multi-angle air purifier. Background Technology

[0002] With rapid urbanization, air purification equipment has become a necessity in modern homes and offices. Traditional household air purifiers mostly use a fixed structure, typically expelling air in one direction, resulting in limited purification range and low airflow circulation efficiency. Especially in large spaces or environments with many obstacles, traditional equipment struggles to achieve uniform coverage, easily creating purification dead zones. While some high-end products attempt to use rotating air outlet designs, their complex structures lack flexible multi-dimensional adjustment capabilities, failing to dynamically adjust the purification angle and height according to actual needs.

[0003] Therefore, there is an urgent need for an air purifier that can efficiently cover multiple areas, support flexible adjustment, and has a compact structure. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a splicing multi-angle air purifier.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A modular multi-angle air purifier includes a central circular support base. A support horizontal plate is rotatably mounted on the upper end of the central circular support base. A support frame is also provided on the central circular support base. A circular shell for accommodating the support frame and coaxially arranged with the central circular support base is provided on the support horizontal plate. Air purifier bodies are provided on both sides of the circular shell on the support frame. An air outlet sleeve for air outlet is movably fitted on the upper end of the air purifier body. An air outlet is provided on one side of the air outlet sleeve. A power drive device, a rotary transmission component, a lifting transmission component, and a power switching clutch component are also provided on the support frame. The rotary transmission component drives the support horizontal plate to rotate around the central circular support base. The lifting transmission component drives the air outlet sleeve to move up and down relative to the air purifier body. The power switching clutch component allows the rotary transmission component and the lifting transmission component to be connected to the power drive device simultaneously, or allows the lifting transmission component to be connected to the power drive device alone.

[0007] In some embodiments, the power drive device includes a motor disposed on the support frame, wherein the output shaft of the motor is coaxially arranged with the annular housing and a drive gear is mounted thereon.

[0008] In some embodiments, the rotary transmission assembly includes a gear ring coaxially disposed on the inner wall of the annular housing.

[0009] In some embodiments, the lifting transmission assembly includes a rotating shaft coaxially rotatably disposed on the upper end of the support frame, a cylindrical cam coaxially disposed on the upper end of the rotating shaft, a guide groove disposed on the outer wall of the cylindrical cam, a guide post disposed on one side of the air outlet sleeve, and one end of the guide post disposed in the guide groove.

[0010] In some embodiments, the power switching clutch assembly includes a sliding shaft that slides up and down on one side of the support frame and a telescopic motor. An annular sleeve is provided on the output shaft of the telescopic motor. An annular groove is provided on the outer wall of the sliding shaft, and the annular sleeve is fitted into the annular groove. An upper transmission gear is provided at the upper end of the sliding shaft, and a lower transmission gear is provided at the lower end. A secondary gear is provided on the rotating shaft. A first locking assembly is also provided on the support frame. The lower transmission gear is located between the drive gear and the gear ring. When the sliding shaft slides downwards, the drive gear, lower transmission gear, and gear ring mesh sequentially, and the upper transmission gear disengages from the secondary gear. Simultaneously, the first locking assembly locks the secondary gear. When the sliding shaft slides upwards, the lower transmission gear meshes with the drive gear, disengages from the gear ring, and the upper transmission gear unlocks the first locking assembly and simultaneously meshes with the secondary gear.

[0011] In some embodiments, the first locking component includes a first square post disposed at the upper end of the support frame and extending downward, a first square sleeve sleeved at the lower end of the first square post, and a first spring disposed inside the first square sleeve, a first top post and a first locking piece disposed at the lower end of the first square sleeve, the lower end of the first top post having a spherical structure and abutting against the upper end face of the upper transmission gear, when the upper transmission gear disengages from the secondary gear, the first locking piece engages in the tooth groove of the secondary gear, and when the upper transmission gear slides upward and meshes with the secondary gear, the first locking piece disengages from the tooth groove of the secondary gear.

[0012] In some embodiments, a second locking component is also provided on the support frame. When the lower drive gear disengages from the gear ring, the second locking component can lock the gear ring. When the lower drive gear slides downward and engages with the gear ring, the second locking component can be unlocked by the lower drive gear.

[0013] In some embodiments, the second locking component includes a second square post located at the lower end of the support frame and extending upward, a second square sleeve fitted on the upper end of the second square post, and a second spring disposed inside the second square sleeve. A second top post and a second locking piece are disposed at the upper end of the second square sleeve. The upper end of the second top post has a spherical structure and abuts against the lower end face of the lower transmission gear. When the lower transmission gear disengages from the gear ring, the second locking piece is inserted into the tooth groove of the gear ring. When the lower transmission gear slides downward and meshes with the gear ring, the second locking piece disengages from the tooth groove of the gear ring.

[0014] In some embodiments, an anti-slip pad is provided at the bottom end of the central annular support.

[0015] In some embodiments, a movable wheel is provided at the lower end of the support cross plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The rotating transmission component drives the support plate to rotate around the central ring support base, which in turn drives the air purifier body on both sides to rotate synchronously, achieving 360° multi-directional airflow injection; at the same time, combined with the lifting transmission component to adjust the height of the air outlet sleeve, a three-dimensional purification space is formed, eliminating the limitation of the traditional equipment's unidirectional air outlet; thus, compared with the traditional unidirectional air outlet design, it can eliminate dead corners in space and significantly expand the effective purification range, which is especially suitable for large space scenarios such as open living rooms and office areas;

[0018] 2. The power switching clutch assembly supports two working modes according to usage requirements: In the "rotation + lifting" synchronous mode, the rotation and lifting actions are driven simultaneously by a single power source to reduce redundant energy consumption; in the independent lifting mode, energy consumption is reduced and the life of the components is extended.

[0019] 3. In addition, depending on usage needs, one or two air purifier units can be spliced ​​together for better practicality. Attached Figure Description

[0032] The following detailed description provides various embodiments or examples for carrying out the present invention. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of the invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0033] like Figures 1-12The illustrated multi-angle modular air purifier includes a central circular support base 1. A support cross plate 2 is rotatably mounted on the upper end of the central circular support base 1. A support frame 3 is also provided on the central circular support base 1. An annular shell 4, coaxially aligned with the central circular support base 1, is provided on the support cross plate 2 to accommodate the support frame 3. Air purifier bodies 5 are provided on both sides of the annular shell 4 on the support frame 3. An air outlet sleeve 6 is movably fitted onto the upper end of each air purifier body 5 for air outlet. An air outlet 7 is provided on one side. A power drive device, a rotary transmission assembly, a lifting transmission assembly, and a power switching clutch assembly are also provided on the support frame 3. The rotary transmission assembly is used to drive the support plate 2 to rotate around the central ring support seat 1. The lifting transmission assembly is used to drive the air outlet sleeve 6 to move up and down relative to the air purifier body 5. The power switching clutch assembly can connect the rotary transmission assembly and the lifting transmission assembly to the power drive device at the same time, or the power switching clutch assembly can connect the lifting transmission assembly to the power drive device alone.

[0034] According to the above structure, the support plate 2 is driven to rotate around the central ring support seat 1 by the rotary transmission component, which drives the air purifier 5 on both sides to rotate synchronously, realizing 360° multi-directional airflow injection; at the same time, the height of the air outlet sleeve 6 is adjusted by the lifting transmission component to form a three-dimensional purification space, eliminating the limitation of the traditional equipment's unidirectional air outlet; thus, compared with the traditional unidirectional air outlet design, it can eliminate dead corners in space and significantly expand the effective purification range, which is especially suitable for large space scenarios such as open living rooms and office areas.

[0035] After starting the power drive unit, the power switching clutch component selects the drive mode:

[0036] Mode 1 (rotation + lifting): Power is simultaneously transmitted to the rotation transmission component (driving the support plate 2 to rotate) and the lifting transmission component (adjusting the height of the air outlet sleeve 6).

[0037] Mode 2 (Lifting Only): The power only drives the lifting transmission component, and the rotation function is suspended.

[0038] Thus, the power switching clutch component can support two working modes according to usage requirements: in the "rotation + lifting" synchronous mode, the rotation and lifting actions are driven simultaneously by a single power source to reduce redundant energy consumption; in the lifting mode alone, energy consumption is reduced and component life is extended.

[0039] In addition, the air purifier bodies 5 on both sides are detachable and can be spliced ​​together, so one or two air purifier bodies 5 can be spliced ​​together according to usage needs, which is more practical.

[0040] In this invention, the power drive device includes a motor 21 mounted on the support frame 3, and the output shaft of the motor 21 is coaxially arranged with the annular housing 4 and a drive gear 22 is mounted thereon.

[0041] In this invention, the rotary transmission assembly includes a gear ring 31 coaxially disposed on the inner wall of the annular housing 4.

[0042] See Figure 1 , Figure 10 As shown, the lifting transmission assembly includes a rotating shaft 41 coaxially rotatably mounted on the upper end of the support frame 3. A cylindrical cam 42 is coaxially mounted on the upper end of the rotating shaft 41. The rotating shaft 41 is mounted on the upper end of the support frame 3 via bearings. The cylindrical cam 42 is interference-fitted with the rotating shaft 41. A guide groove 43 is provided on the outer wall of the cylindrical cam 42. A guide post 44 is provided on one side of the air outlet sleeve 6. One end of the guide post 44 is located in the guide groove 43. The guide groove 43 of the cylindrical cam 42 cooperates with the guide post 44 to convert the rotational motion into the linear lifting of the air outlet sleeve 6, avoiding jamming.

[0043] See Figures 4-9 As shown, the power switching clutch assembly includes a sliding shaft 51 that slides vertically along one side of the support frame 3 and a telescopic motor 52. An annular sleeve 53 is provided on the output shaft of the telescopic motor 52. An annular groove 54 is provided on the outer wall of the sliding shaft 51, and the annular sleeve 53 is fitted into the annular groove 54. An upper transmission gear 55 is provided at the upper end of the sliding shaft 51, and a lower transmission gear 56 is provided at the lower end. A secondary gear 57 is provided on the rotating shaft 41. A first locking assembly is also provided on the support frame 3. The transmission gear 56 is located between the drive gear 22 and the gear ring 31. When the sliding shaft 51 slides downward, the drive gear 22, the lower transmission gear 56, and the gear ring 31 mesh in sequence, and the upper transmission gear 55 disengages from the secondary gear 57. At the same time, the first locking component locks the secondary gear 57. When the sliding shaft 51 slides upward, the lower transmission gear 56 meshes with the drive gear 22, disengages from the gear ring 31, the upper transmission gear 55 unlocks the first locking component, and simultaneously meshes with the secondary gear 57.

[0044] The telescopic motor 52 drives the sliding shaft 51 to move up and down, thereby switching between mode one (rotation + lifting) and mode two (lifting only).

[0045] Specifically, in mode one (rotation + lifting), the telescopic motor 52 drives the sliding shaft 51 to move downward. At this time, the drive gear 22, the lower transmission gear 56, and the gear ring 31 mesh in sequence, and the upper transmission gear 55 disengages from the secondary gear 57. At the same time, the first locking component locks the secondary gear 57. Then, the motor 21 works to drive the drive gear 22 to rotate. Under the transmission of the lower transmission gear 56, the gear ring 31 is driven to rotate, and the annular housing 4 and the support frame 3 rotate synchronously around the central annular support seat 1. While the air purifier body 5 and the air outlet sleeve 6 rotate, the guide post 44 on the air outlet sleeve 6 moves in the guide groove 43 on the outer wall of the cylindrical cam 42. Since the cylindrical cam 42 is locked by the first locking component at this time, the guide post 44 can move up and down following the trajectory of the guide groove 43, thereby moving the air outlet sleeve 6 up and down to emit air, achieving the air outlet effect of rotation and lifting.

[0046] In Mode 2 (rotation only): the telescopic motor 52 drives the sliding shaft 51 to move upward, the upper transmission gear 55 unlocks the first locking component and simultaneously meshes with the secondary gear 57, while the lower transmission gear 56 meshes with the drive gear 22 and disengages from the gear ring 31; then the motor 21 works to drive the drive gear 22 to rotate and mesh with the lower transmission gear 56, and drive the sliding shaft 51 and the upper transmission gear 55 to rotate, while the lower transmission gear 56 disengages from the gear ring 31, so the gear ring 31, the annular housing 4 and the support frame 3 remain stationary, that is, the support frame 3 does not rotate, while the upper transmission gear 55 meshes with the secondary gear 57, driving the rotating shaft 41 and the cylindrical cam 42 to rotate. Since the air purifier body 5 and the air outlet sleeve 6 are fixed, with the cooperation of the guide column 44 and the guide groove 43, the air outlet sleeve 6 is driven to move up and down to output air, achieving an air output effect of only lifting and lowering.

[0047] See Figure 4 , Figure 5 , Figure 7 , Figure 8 As shown, the first locking assembly includes a first square post 61 located on the upper end of the support frame 3 and extending downward. A first square sleeve 62 is fitted on the lower end of the first square post 61, and a first spring 63 is provided inside the first square sleeve 62. A first top post 64 and a first locking piece 65 are provided at the lower end of the first square sleeve 62. The lower end of the first top post 64 has a spherical structure and abuts against the upper end face of the upper transmission gear 55. When the upper transmission gear 55 disengages from the secondary gear 57, the first locking piece 65 is engaged in the tooth groove of the secondary gear 57. When the upper transmission gear 55 slides upward and meshes with the secondary gear 57, the first locking piece 65 disengages from the tooth groove of the secondary gear 57.

[0048] The specific working principle of the first locking component is as follows: the telescopic motor 52 drives the sliding shaft 51 to move downward, the upper transmission gear 55 disengages from the secondary gear 57, the first spring 63 pushes the first square sleeve 62 to move downward, and the first locking piece 65 is embedded in the tooth groove of the secondary gear 57 to achieve locking; when unlocking, the telescopic motor 52 drives the sliding shaft 51 to move upward, the upper transmission gear 55 rises and meshes with the secondary gear 57, its end face pushes up the first top post 64, and drives the first locking piece 65 to disengage from the tooth groove to achieve unlocking.

[0049] To further improve the stability of the power switching clutch assembly after switching modes, a second locking assembly is also provided on the support frame 3. When the lower transmission gear 56 disengages from the gear ring 31, the second locking assembly can lock the gear ring 31. When the lower transmission gear 56 slides down and meshes with the gear ring 31, the second locking assembly can be unlocked through the lower transmission gear 56.

[0050] The second locking component locks the toothed ring 31 in the lifting-only mode to prevent the support plate 2 from rotating accidentally, thus improving safety.

[0051] See Figure 4 , Figure 6 , Figure 7 , Figure 9 As shown, the second locking assembly includes a second square post 81 located at the lower end of the support frame 3 and extending upward. A second square sleeve 82 is fitted on the upper end of the second square post 81, and a second spring 83 is provided inside the second square sleeve 82. A second top post 84 and a second locking piece 85 are provided on the upper end of the second square sleeve 82. The upper end of the second top post 84 is a spherical structure and abuts against the lower end face of the lower transmission gear 56. When the lower transmission gear 56 disengages from the gear ring 31, the second locking piece 85 is inserted into the tooth groove of the gear ring 31. When the lower transmission gear 56 slides downward and meshes with the gear ring 31, the second locking piece 85 disengages from the tooth groove of the gear ring 31.

[0052] The specific working principle of the second locking component is as follows: the telescopic motor 52 drives the sliding shaft 51 to move upward, the lower transmission gear 56 disengages from the gear ring 31, and the second locking piece 85 is inserted into the tooth groove of the gear ring 31 under the action of the second spring 83, thereby locking the gear ring 31; when unlocking is required, the telescopic motor 52 drives the sliding shaft 51 to move downward, the lower transmission gear 56 presses the second top post 84, and drives the second locking piece 85 to disengage from the gear ring 31, thereby unlocking.

[0053] In this invention, an anti-slip pad is provided at the bottom of the central ring support 1. The anti-slip pad is made of rubber or silicone and is fixed to the bottom of the central ring support 1 by adhesive or screws to increase the friction between the equipment and the ground and prevent displacement during operation.

[0054] In this invention, a movable wheel 10 is provided at the lower end of the supporting horizontal plate 2; this facilitates smoother rotation in rotation mode.
