Description

Technical Field

[0001] This invention relates to the field of filter-type air purifier technology, and particularly to a driven rotating mechanism. Background Technology

[0002] Air pollution is currently quite severe, with the proportion of smoggy days increasing significantly. Existing simple indoor ventilation fans are no longer sufficient to meet daily needs, as they only replace air without purification or humidification functions. Air purifiers solve this problem. With the continuous development of science and technology, people are paying increasing attention to indoor air quality, making air filtration materials play an increasingly important role in environmental governance. At the same time, the continuous development and improvement of dust removal and purification technologies have placed new demands on air filtration materials in terms of quantity, variety, and quality.

[0003] Among them, filter-type air purifiers are a type of air purifier that mainly uses HEPA filters to remove particulate pollutants from the air. They are also the most common type of air purifier on the market, with advantages such as effective purification, safety, simple manufacturing process, and easy installation. However, after prolonged use, excessive dust on the filter of a filter-type air purifier can increase air resistance, requiring regular cleaning and replacement, making subsequent maintenance relatively troublesome.

[0004] Therefore, most filter-type air purifiers on the market are equipped with a self-cleaning filter function. This function involves adding a dust-collecting device inside the air purifier, which, through a rotating mechanism on the chassis, drives the filter to rotate. This allows the dust-collecting device to remove dust from the filter surface, achieving the effect of the air purifier automatically cleaning the filter, increasing its lifespan, and reducing the hassle of manual cleaning. Therefore, the reliability of the filter rotation is one of the key aspects of the self-cleaning function.

[0005] However, in actual use, there are still some shortcomings:

[0006] 1. The composite filter in traditional filter-type air purifiers rotates in a face-to-face manner. During rotation, the reliability of the filter rotation is poor, resulting in poor uniformity of dust removal by the dust collection device.

[0007] 2. Traditional filter-type air purifiers have significant frictional wear between the composite filter and the rotating tray, which accelerates material aging and generates noise.

[0008] In view of this, the present invention proposes a driven rotating mechanism, as well as an air purifier, an air conditioner and an air conditioning fan containing the structure. Summary of the Invention

[0009] This invention provides a driven rotating mechanism for rotating an air purifier filter, which solves the problems of poor reliability of filter rotation in related technologies, frictional loss between the composite filter and the rotating tray, which accelerates material aging and generates noise.

[0010] The technical solution of the present invention is as follows:

[0011] A driven rotating mechanism includes: a secondary air duct assembly, and a base assembly disposed below the secondary air duct assembly;

[0012] A support assembly for supporting the secondary air duct assembly is provided between the secondary air duct assembly and the base assembly.

[0013] A composite filter is provided between the secondary air duct assembly and the base assembly located inside the bracket assembly;

[0014] The secondary air duct assembly includes a secondary air duct bottom cover and a rotating tray installed at the bottom of the secondary air duct bottom cover;

[0015] A composite filter top cover is provided on the top of the composite filter.

[0016] The auxiliary air duct bottom cover, the rotating tray, and the composite filter top cover together constitute a driven rotating mechanism.

[0017] Preferably, the composite filter top cover has a ring-shaped structure and is flat overall;

[0018] Multiple sets of guide ribs of different shapes and sizes are symmetrically arranged on the top of the composite filter cover;

[0019] The guide rib has a trapezoidal cross-sectional shape, and the two upper corners of the trapezoid are rounded.

[0020] The multiple sets of guide ribs are in a parallel state with each other;

[0021] Multiple sets of grooves of different shapes and sizes are formed on the top of the rotating tray;

[0022] The number of grooves and guide ribs are the same and correspond one-to-one.

[0023] Preferably, a tray mounting slot is provided on the bottom cover of the secondary air duct for mounting a rotating tray;

[0024] A slide rail is provided on the bottom cover of the secondary air duct located on the outer periphery of the tray mounting slot;

[0025] Two limiting ribs are provided on the inner side of the slide rail;

[0026] The two limiting ribs are aligned.

[0027] Preferably, two slots that cooperate with the limiting ribs are formed on the outer periphery of the rotating tray;

[0028] The two card slots are aligned.

[0029] Preferably, the secondary air duct assembly further includes a secondary air duct housing installed on the top of the secondary air duct bottom cover;

[0030] Fan blades are installed inside the outer casing of the secondary air duct.

[0031] Preferably, the base assembly includes a rotating chassis, a base body, and a motor;

[0032] The rotating chassis is rotatably connected to the top of the base body and is used to mount the composite filter.

[0033] The motor is installed inside the base body and is used to rotate the rotating chassis.

[0034] Preferably, the outer circumference of the rotating tray is rotatably sleeved on the inner side of the slide.

[0035] Furthermore, the present invention provides an air purifier comprising the driven engagement rotating mechanism as described above, characterized in that the driven engagement rotating mechanism is detachably disposed within the air purifier.

[0036] Furthermore, the present invention provides an air conditioner including the driven engagement rotation mechanism as described above, characterized in that the driven engagement rotation mechanism is detachably disposed within the air conditioner.

[0037] Furthermore, the present invention provides an air conditioning fan including the driven engagement rotation mechanism as described above, characterized in that the driven engagement rotation mechanism is detachably disposed within the air conditioner.

[0038] Compared with the prior art, the advantages of the present invention are as follows: In the present invention, the secondary air duct assembly includes a secondary air duct bottom cover and a rotating tray installed at the bottom of the secondary air duct bottom cover. A composite filter top cover is provided on the top of the composite filter. The secondary air duct bottom cover, the rotating tray, and the composite filter top cover together constitute a driven and rotating mechanism. A number of guide ribs of different shapes and sizes are symmetrically arranged on the top of the composite filter top cover. A number of grooves of different shapes and sizes are opened on the top of the rotating tray. The number of grooves is the same as that of the guide ribs and they correspond one-to-one. When the composite filter rotates, the guide ribs can drive the rotating tray to rotate through the grooves. The grooves can also fix the composite filter in the opposite direction, making the composite filter more stable and reliable when rotating.

[0039] In this invention, the driven rotating mechanism, which consists of the auxiliary air duct bottom cover, the rotating tray, and the composite filter top cover, can reduce frictional wear between the composite filter and the rotating tray, avoid material aging, and reduce noise compared to rotating in a face-to-face manner.

[0040] In this invention, two limiting ribs are aligned on the bottom cover of the secondary air duct, and two slots that cooperate with the limiting ribs are aligned on the outer periphery of the rotating tray. When the composite filter is not installed, the highest point of the guide rib on the top cover of the composite filter is higher than the lowest point of the rotating tray and higher than the top of the groove on the rotating tray. At this time, the slot of the rotating tray will be locked on the limiting ribs of the bottom cover of the secondary air duct, so that the rotating tray cannot rotate when the composite filter is not installed, thereby improving the stability during installation.

[0041] In this invention, when the composite filter is installed, the guide ribs on the top cover of the composite filter are inserted into the groove and the rotating tray is raised a certain distance, so that the slot on the rotating tray is away from the limiting ribs on the bottom cover of the secondary air duct, so that the rotating tray can rotate smoothly when the composite filter is installed, which has good practical performance.

Detailed Implementation

[0056] The invention will now be further described with reference to the accompanying drawings.

[0057] Example 1:

[0058] Please see Figure 1 A driven rotating mechanism, comprising: a secondary air duct assembly 2;

[0059] Base assembly 4 is located below secondary air duct assembly 2;

[0060] The bracket assembly 3 is disposed between the secondary air duct assembly 2 and the base assembly 4, and is used to support the secondary air duct assembly 2;

[0061] The composite filter 1 is located between the secondary air duct assembly 2 and the base assembly 4 inside the bracket assembly 3, and can be installed and removed between the secondary air duct assembly 2 and the base assembly 4.

[0062] Please see Figure 1 and Figure 2 The secondary air duct assembly 2 includes a secondary air duct bottom cover 22 and a rotating tray 24 installed at the bottom of the secondary air duct bottom cover 22;

[0063] A tray mounting slot 23 is provided on the bottom cover 22 of the secondary air duct for mounting the rotating tray 24;

[0064] In addition, the secondary air duct assembly 2 also includes a secondary air duct housing 21 installed on the top of the secondary air duct bottom cover 22, and a fan blade 25 is provided inside the secondary air duct housing 21.

[0065] A composite filter top cover 5 is provided on the top of the composite filter 1. The composite filter top cover 5 has a flat annular structure.

[0066] It is worth noting that the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5 together constitute a driven rotating mechanism.

[0067] Please see Figure 3 The base assembly 4 includes a rotating base 41, a base body 42, and a motor 43, wherein:

[0068] The rotating base 41 is rotatably connected to the top of the base body 42 and is used to mount the composite filter 1.

[0069] Motor 43 is installed inside the base body 42 and is used to rotate the rotating chassis 41;

[0070] It should be noted that when working, the power is turned on and the motor 43 is started. The motor 43 can drive the rotating chassis 41 to rotate through its output shaft. During the rotation of the rotating chassis 41, since the composite filter 1 is located between the secondary air duct assembly 2 and the base assembly 4 inside the support assembly 3, the rotating chassis 41 can drive the composite filter 1 to rotate between the secondary air duct assembly 2 and the base assembly 4 inside the support assembly 3.

[0071] It is worth noting that when the composite filter 1 rotates between the secondary air duct assembly 2 and the base assembly 4 located inside the support assembly 3, the composite filter 1 can rotate more stably through the cooperation of the driven rotating mechanism composed of the secondary air duct bottom cover 22, the rotating tray 24 and the composite filter top cover 5.

[0072] Please see Figure 6 Multiple sets of guide ribs 51 of different shapes and sizes are symmetrically arranged on the top of the composite filter cover 5;

[0073] Furthermore, the multiple sets of guide ribs 51 are in a parallel state with each other;

[0074] It is worth noting that the cross-sectional shape of the guide rib 51 is trapezoidal, and the two upper corners of the trapezoid are rounded.

[0075] Please see Figure 5 Multiple sets of grooves 241 of different shapes and sizes are provided on the top of the rotating tray 24;

[0076] Among them, the number of grooves 241 and guide ribs 51 are the same and correspond one-to-one;

[0077] Furthermore, the guide rib 51 and the groove 241 can cooperate with each other.

[0078] It should be noted that the two corners at the upper end of the trapezoidal guide rib 51 are rounded to facilitate the insertion and removal of the trapezoidal guide rib 51 into the groove 241.

[0079] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 6 When performing work:

[0080] First, the trapezoidal guide rib 51 is slidably inserted into the groove 241;

[0081] Next, after multiple trapezoidal guide ribs 51 are inserted into the grooves 241, when the composite filter 1 rotates, the trapezoidal guide ribs 51 can drive the rotating tray 24 to rotate through the grooves 241.

[0082] The trapezoidal guide ribs 51 and the grooves 241 are designed so that while the trapezoidal guide ribs 51 drive the rotating tray 24 to rotate through the grooves 241, the grooves 241 can also fix the composite filter 1 in the opposite direction, making the composite filter 1 more stable and reliable when rotating.

[0083] Furthermore, compared to traditional filter-type air purifiers that rotate in a face-to-face manner, the passive rotating mechanism of this invention, which consists of a secondary air duct bottom cover 22, a rotating tray 24, and a composite filter top cover 5, can reduce frictional wear between the composite filter 1 and the rotating tray 24, prevent material aging, and reduce noise.

[0084] Furthermore, since the composite filter 1 is a cylindrical hollow shape, in order to make the trapezoidal guide ribs 51 and the grooves 241 match more smoothly when the composite filter 1 is inserted and removed, this matching structure is designed in a staggered arrangement, which can play a guiding role, so that the guide ribs 51 can smoothly match the grooves 241 during the insertion and removal of the composite filter 1.

[0085] Example 2:

[0086] Please see Figure 4 and Figure 7 A slide rail 222 is provided on the bottom cover 22 of the secondary air duct located on the outer periphery of the tray mounting slot 23;

[0087] Furthermore, the outer periphery of the rotating tray 24 is rotatably fitted inside the slide rail 222;

[0088] Two limiting ribs 221 are provided inside the slide 222, and the two limiting ribs 221 are aligned.

[0089] Please see Figure 5Two slots 242 are provided on the outer periphery of the rotating tray 24, and the two slots 242 respectively cooperate with two limiting ribs 221;

[0090] It is worth noting that the two slots 242 are aligned to ensure that they can be properly engaged with the two limiting ribs 221.

[0091] Please see Figure 8 At this time, the composite filter 1 has not yet been installed inside the bracket assembly 3 between the secondary air duct assembly 2 and the base assembly 4;

[0092] Before the composite filter 1 is assembled, that is, before the composite filter 1 is installed, in order to prevent the groove 241 of the rotating tray 24 from not being parallel to the installation direction of the trapezoidal guide rib 51 on the top cover 5 of the composite filter, so that the trapezoidal guide rib 51 on the top cover 5 of the composite filter cannot be guided into the groove 241, thus preventing the composite filter 1 from being installed, two limiting ribs 221 are designed on the bottom cover 22 of the secondary air duct, and two slots 242 are designed on the rotating tray 24.

[0093] When the driven rotating mechanism is assembled in the following state Figure 8 , Figure 10 As shown (when the composite filter 1 is not installed), the highest point of the guide rib 51 on the top cover 5 of the composite filter is higher than the lowest point of the rotating tray 24;

[0094] Furthermore, the highest point of the guide rib 51 is higher than the top of the groove 241 on the rotating tray 24;

[0095] At this time, the slot 242 of the rotating tray 24 will be locked on the limiting rib 221 of the auxiliary air duct bottom cover 22, so that the rotating tray 24 cannot rotate when the composite filter 1 is not installed.

[0096] When installing composite filter 1, the driven rotating mechanism is assembled as follows: Figure 9 , Figure 11 As shown:

[0097] The trapezoidal guide ribs 51 on the top cover 5 of the composite filter screen will lift the rotating tray 24 a certain distance, so that the slot 242 of the rotating tray 24 is away from the limiting ribs 221 on the bottom cover 22 of the secondary air duct, so that the rotating tray 24 can rotate when the composite filter screen 1 is installed.

[0098] Working principle and usage process:

[0099] First, when the composite filter 1 is not installed, the highest point of the trapezoidal guide rib 51 on the top cover 5 of the composite filter is higher than the lowest point of the rotating tray 24 and higher than the top of the groove 241 on the rotating tray 24. At this time, the slot 242 of the rotating tray 24 will be stuck on the limiting rib 221 of the auxiliary air duct bottom cover 22, so that the rotating tray 24 cannot rotate when the composite filter 1 is not installed.

[0100] When the composite filter 1 is installed, the guide ribs 51 on the top cover 5 of the composite filter will be inserted into the groove 241 and lift the rotating tray 24 a certain distance, so that the slot 242 on the rotating tray 24 is away from the limiting ribs 221 on the bottom cover 22 of the secondary air duct, so that the rotating tray 24 can rotate when the composite filter 1 is installed.

[0101] Next, as the composite filter 1 rotates, the trapezoidal guide ribs 51 drive the rotating tray 24 to rotate via the grooves 241. The grooves 241 also provide a counter-fixing effect on the composite filter 1, making its rotation more stable and reliable. Furthermore, compared to rotating in a face-to-face manner, the driven-coupling rotation mechanism of this invention, composed of the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5, reduces frictional wear between the composite filter 1 and the rotating tray 24, preventing material aging and reducing noise.

[0102] In addition, since the composite filter 1 is a cylindrical hollow shape, in order to make the guide ribs 51 and the grooves 241 match more smoothly when the composite filter 1 is installed and removed, the matching structure is designed in a staggered arrangement, which can play a guiding role, so that the guide ribs 51 can match the grooves 241 smoothly during the installation and removal process.

[0103] Example 3:

[0104] Furthermore, the present invention provides an air purifier comprising the driven engagement rotating mechanism as described above, characterized in that the driven engagement rotating mechanism is detachably disposed within the air purifier.

[0105] The driven rotating mechanism within the air purifier can be found in [reference]. Figure 1 Includes: secondary air duct component 2;

[0106] Base assembly 4 is located below secondary air duct assembly 2;

[0107] The bracket assembly 3 is disposed between the secondary air duct assembly 2 and the base assembly 4, and is used to support the secondary air duct assembly 2;

[0108] The composite filter 1 is located between the secondary air duct assembly 2 and the base assembly 4 inside the bracket assembly 3, and can be installed and removed between the secondary air duct assembly 2 and the base assembly 4.

[0109] Please see Figure 1 and Figure 2 The secondary air duct assembly 2 includes a secondary air duct bottom cover 22 and a rotating tray 24 installed at the bottom of the secondary air duct bottom cover 22;

[0110] A tray mounting slot 23 is provided on the bottom cover 22 of the secondary air duct for mounting the rotating tray 24;

[0111] In addition, the secondary air duct assembly 2 also includes a secondary air duct housing 21 installed on the top of the secondary air duct bottom cover 22, and a fan blade 25 is provided inside the secondary air duct housing 21.

[0112] A composite filter top cover 5 is provided on the top of the composite filter 1. The composite filter top cover 5 has a flat annular structure.

[0113] It is worth noting that the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5 together constitute a driven rotating mechanism.

[0114] Please see Figure 3 The base assembly 4 includes a rotating base 41, a base body 42, and a motor 43, wherein:

[0115] The rotating base 41 is rotatably connected to the top of the base body 42 and is used to mount the composite filter 1.

[0116] Motor 43 is installed inside the base body 42 and is used to rotate the rotating chassis 41;

[0117] It should be noted that when working, the power is turned on and the motor 43 is started. The motor 43 can drive the rotating chassis 41 to rotate through its output shaft. During the rotation of the rotating chassis 41, since the composite filter 1 is located between the secondary air duct assembly 2 and the base assembly 4 inside the support assembly 3, the rotating chassis 41 can drive the composite filter 1 to rotate between the secondary air duct assembly 2 and the base assembly 4 inside the support assembly 3.

[0118] It is worth noting that when the composite filter 1 rotates between the secondary air duct assembly 2 and the base assembly 4 located inside the support assembly 3, the composite filter 1 can rotate more stably through the cooperation of the driven rotating mechanism composed of the secondary air duct bottom cover 22, the rotating tray 24 and the composite filter top cover 5.

[0119] Please see Figure 6 Multiple sets of guide ribs 51 of different shapes and sizes are symmetrically arranged on the top of the composite filter cover 5;

[0120] Furthermore, the multiple sets of guide ribs 51 are in a parallel state with each other;

[0121] It is worth noting that the cross-sectional shape of the guide rib 51 is trapezoidal, and the two upper corners of the trapezoid are rounded.

[0122] Please see Figure 5 Multiple sets of grooves 241 of different shapes and sizes are provided on the top of the rotating tray 24;

[0123] Among them, the number of grooves 241 and guide ribs 51 are the same and correspond one-to-one;

[0124] Furthermore, the guide rib 51 and the groove 241 can cooperate with each other.

[0125] It should be noted that the two corners at the upper end of the trapezoidal guide rib 51 are rounded to facilitate the insertion and removal of the trapezoidal guide rib 51 into the groove 241.

[0126] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 6 When performing work:

[0127] First, the trapezoidal guide rib 51 is slidably inserted into the groove 241;

[0128] Next, after multiple trapezoidal guide ribs 51 are inserted into the grooves 241, when the composite filter 1 rotates, the trapezoidal guide ribs 51 can drive the rotating tray 24 to rotate through the grooves 241.

[0129] The trapezoidal guide ribs 51 and the grooves 241 are designed so that while the trapezoidal guide ribs 51 drive the rotating tray 24 to rotate through the grooves 241, the grooves 241 can also fix the composite filter 1 in the opposite direction, making the composite filter 1 more stable and reliable when rotating.

[0130] Furthermore, compared to traditional air conditioners that rotate in a face-to-face manner, the passive rotating mechanism of this invention, which consists of the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5, can reduce frictional wear between the composite filter 1 and the rotating tray 24, prevent material aging, and reduce noise.

[0131] Furthermore, since the composite filter 1 is a cylindrical hollow shape, in order to make the trapezoidal guide ribs 51 and the grooves 241 match more smoothly when the composite filter 1 is inserted and removed, this matching structure is designed in a staggered arrangement, which can play a guiding role, so that the guide ribs 51 can smoothly match the grooves 241 during the insertion and removal of the composite filter 1.

[0132] Further, please refer to Figure 4 and Figure 7 In the driven rotating mechanism inside the air purifier, a slide 222 is provided on the bottom cover 22 of the secondary air duct located on the outer periphery of the tray mounting slot 23;

[0133] Furthermore, the outer periphery of the rotating tray 24 is rotatably fitted inside the slide rail 222;

[0134] Two limiting ribs 221 are provided inside the slide 222, and the two limiting ribs 221 are aligned.

[0135] Please see Figure 5 Two slots 242 are provided on the outer periphery of the rotating tray 24, and the two slots 242 respectively cooperate with two limiting ribs 221;

[0136] It is worth noting that the two slots 242 are aligned to ensure that they can be properly engaged with the two limiting ribs 221.

[0137] Please see Figure 8 At this time, the composite filter 1 has not yet been installed inside the bracket assembly 3 between the secondary air duct assembly 2 and the base assembly 4;

[0138] Before the composite filter 1 is assembled, that is, before the composite filter 1 is installed, in order to prevent the groove 241 of the rotating tray 24 from not being parallel to the installation direction of the trapezoidal guide rib 51 on the top cover 5 of the composite filter, so that the trapezoidal guide rib 51 on the top cover 5 of the composite filter cannot be guided into the groove 241, thus preventing the composite filter 1 from being installed, two limiting ribs 221 are designed on the bottom cover 22 of the secondary air duct, and two slots 242 are designed on the rotating tray 24.

[0139] When the driven rotating mechanism is assembled in the following state Figure 8 , Figure 10 As shown (when the composite filter 1 is not installed), the highest point of the guide rib 51 on the top cover 5 of the composite filter is higher than the lowest point of the rotating tray 24;

[0140] Furthermore, the highest point of the guide rib 51 is higher than the top of the groove 241 on the rotating tray 24;

[0141] At this time, the slot 242 of the rotating tray 24 will be locked on the limiting rib 221 of the auxiliary air duct bottom cover 22, so that the rotating tray 24 cannot rotate when the composite filter 1 is not installed.

[0142] When installing composite filter 1, the driven rotating mechanism is assembled as follows: Figure 9 , Figure 11 As shown:

[0143] The trapezoidal guide ribs 51 on the top cover 5 of the composite filter screen will lift the rotating tray 24 a certain distance, so that the slot 242 of the rotating tray 24 is away from the limiting ribs 221 on the bottom cover 22 of the secondary air duct, so that the rotating tray 24 can rotate when the composite filter screen 1 is installed.

[0144] Working principle and usage process:

[0145] First, when the composite filter 1 is not installed, the highest point of the trapezoidal guide rib 51 on the top cover 5 of the composite filter is higher than the lowest point of the rotating tray 24 and higher than the top of the groove 241 on the rotating tray 24. At this time, the slot 242 of the rotating tray 24 will be stuck on the limiting rib 221 of the auxiliary air duct bottom cover 22, so that the rotating tray 24 cannot rotate when the composite filter 1 is not installed.

[0146] When the composite filter 1 is installed, the guide ribs 51 on the top cover 5 of the composite filter will be inserted into the groove 241 and lift the rotating tray 24 a certain distance, so that the slot 242 on the rotating tray 24 is away from the limiting ribs 221 on the bottom cover 22 of the secondary air duct, so that the rotating tray 24 can rotate when the composite filter 1 is installed.

[0147] Next, as the composite filter 1 rotates, the trapezoidal guide ribs 51 drive the rotating tray 24 to rotate via the grooves 241. The grooves 241 also provide a counter-fixing effect on the composite filter 1, making its rotation more stable and reliable. Furthermore, compared to rotating in a face-to-face manner, the driven-coupling rotation mechanism of this invention, composed of the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5, reduces frictional wear between the composite filter 1 and the rotating tray 24, preventing material aging and reducing noise.

[0148] In addition, since the composite filter 1 is a cylindrical hollow shape, in order to make the guide ribs 51 and the grooves 241 match more smoothly when the composite filter 1 is installed and removed, the matching structure is designed in a staggered arrangement, which can play a guiding role, so that the guide ribs 51 can match the grooves 241 smoothly during the installation and removal process.

[0149] Example 4: Further, the present invention provides an air conditioner including the driven engagement rotation mechanism as described above, characterized in that the driven engagement rotation mechanism is detachably provided inside the air conditioner.

[0150] The driven rotating mechanism inside the air conditioner can be referred to. Figure 1 Includes: secondary air duct component 2;

[0151] Base assembly 4 is located below secondary air duct assembly 2;

[0152] The bracket assembly 3 is disposed between the secondary air duct assembly 2 and the base assembly 4, and is used to support the secondary air duct assembly 2;

[0153] The composite filter 1 is located between the secondary air duct assembly 2 and the base assembly 4 inside the bracket assembly 3, and can be installed and removed between the secondary air duct assembly 2 and the base assembly 4.

[0154] Please see Figure 1 and Figure 2 The secondary air duct assembly 2 includes a secondary air duct bottom cover 22 and a rotating tray 24 installed at the bottom of the secondary air duct bottom cover 22;

[0155] A tray mounting slot 23 is provided on the bottom cover 22 of the secondary air duct for mounting the rotating tray 24;

[0156] In addition, the secondary air duct assembly 2 also includes a secondary air duct housing 21 installed on the top of the secondary air duct bottom cover 22, and a fan blade 25 is provided inside the secondary air duct housing 21.

[0157] A composite filter top cover 5 is provided on the top of the composite filter 1. The composite filter top cover 5 has a flat annular structure.

[0158] It is worth noting that the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5 together constitute a driven rotating mechanism.

[0159] Please see Figure 3 The base assembly 4 includes a rotating base 41, a base body 42, and a motor 43, wherein:

[0160] The rotating base 41 is rotatably connected to the top of the base body 42 and is used to mount the composite filter 1.

[0161] Motor 43 is installed inside the base body 42 and is used to rotate the rotating chassis 41;

[0162] It should be noted that when working, the power is turned on and the motor 43 is started. The motor 43 can drive the rotating chassis 41 to rotate through its output shaft. During the rotation of the rotating chassis 41, since the composite filter 1 is located between the secondary air duct assembly 2 and the base assembly 4 inside the support assembly 3, the rotating chassis 41 can drive the composite filter 1 to rotate between the secondary air duct assembly 2 and the base assembly 4 inside the support assembly 3.

[0163] It is worth noting that when the composite filter 1 rotates between the secondary air duct assembly 2 and the base assembly 4 located inside the support assembly 3, the composite filter 1 can rotate more stably through the cooperation of the driven rotating mechanism composed of the secondary air duct bottom cover 22, the rotating tray 24 and the composite filter top cover 5.

[0164] Please see Figure 6 Multiple sets of guide ribs 51 of different shapes and sizes are symmetrically arranged on the top of the composite filter cover 5;

[0165] Furthermore, the multiple sets of guide ribs 51 are in a parallel state with each other;

[0166] It is worth noting that the cross-sectional shape of the guide rib 51 is trapezoidal, and the two upper corners of the trapezoid are rounded.

[0167] Please see Figure 5 Multiple sets of grooves 241 of different shapes and sizes are provided on the top of the rotating tray 24;

[0168] Among them, the number of grooves 241 and guide ribs 51 are the same and correspond one-to-one;

[0169] Furthermore, the guide rib 51 and the groove 241 can cooperate with each other.

[0170] It should be noted that the two corners at the upper end of the trapezoidal guide rib 51 are rounded to facilitate the insertion and removal of the trapezoidal guide rib 51 into the groove 241.

[0171] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 6 When performing work:

[0172] First, the trapezoidal guide rib 51 is slidably inserted into the groove 241;

[0173] Next, after multiple trapezoidal guide ribs 51 are inserted into the grooves 241, when the composite filter 1 rotates, the trapezoidal guide ribs 51 can drive the rotating tray 24 to rotate through the grooves 241.

[0174] The trapezoidal guide ribs 51 and the grooves 241 are designed so that while the trapezoidal guide ribs 51 drive the rotating tray 24 to rotate through the grooves 241, the grooves 241 can also fix the composite filter 1 in the opposite direction, making the composite filter 1 more stable and reliable when rotating.

[0175] Furthermore, compared to traditional filter-type air purifiers that rotate in a face-to-face manner, the passive rotating mechanism of this invention, which consists of a secondary air duct bottom cover 22, a rotating tray 24, and a composite filter top cover 5, can reduce frictional wear between the composite filter 1 and the rotating tray 24, prevent material aging, and reduce noise.

[0176] Furthermore, since the composite filter 1 is a cylindrical hollow shape, in order to make the trapezoidal guide ribs 51 and the grooves 241 match more smoothly when the composite filter 1 is inserted and removed, this matching structure is designed in a staggered arrangement, which can play a guiding role, so that the guide ribs 51 can smoothly match the grooves 241 during the insertion and removal of the composite filter 1.

[0177] Further, please refer to Figure 4 and Figure 7 In the driven rotating mechanism inside the air conditioner, a slide rail 222 is provided on the bottom cover 22 of the secondary air duct located on the outer periphery of the tray mounting slot 23;

[0178] Furthermore, the outer periphery of the rotating tray 24 is rotatably fitted inside the slide rail 222;

[0179] Two limiting ribs 221 are provided inside the slide 222, and the two limiting ribs 221 are aligned.

[0180] Please see Figure 5 Two slots 242 are provided on the outer periphery of the rotating tray 24, and the two slots 242 respectively cooperate with two limiting ribs 221;

[0181] It is worth noting that the two slots 242 are aligned to ensure that they can be properly engaged with the two limiting ribs 221.

[0182] Please see Figure 8 At this time, the composite filter 1 has not yet been installed inside the bracket assembly 3 between the secondary air duct assembly 2 and the base assembly 4;

[0183] Before the composite filter 1 is assembled, that is, before the composite filter 1 is installed, in order to prevent the groove 241 of the rotating tray 24 from not being parallel to the installation direction of the trapezoidal guide rib 51 on the top cover 5 of the composite filter, so that the trapezoidal guide rib 51 on the top cover 5 of the composite filter cannot be guided into the groove 241, thus preventing the composite filter 1 from being installed, two limiting ribs 221 are designed on the bottom cover 22 of the secondary air duct, and two slots 242 are designed on the rotating tray 24.

[0184] When the driven rotating mechanism is assembled in the following state Figure 8 , Figure 10 As shown (when the composite filter 1 is not installed), the highest point of the guide rib 51 on the top cover 5 of the composite filter is higher than the lowest point of the rotating tray 24;

[0185] Furthermore, the highest point of the guide rib 51 is higher than the top of the groove 241 on the rotating tray 24;

[0186] At this time, the slot 242 of the rotating tray 24 will be locked on the limiting rib 221 of the auxiliary air duct bottom cover 22, so that the rotating tray 24 cannot rotate when the composite filter 1 is not installed.

[0187] When installing composite filter 1, the driven rotating mechanism is assembled as follows: Figure 9 , Figure 11 As shown:

[0188] The trapezoidal guide ribs 51 on the top cover 5 of the composite filter screen will lift the rotating tray 24 a certain distance, so that the slot 242 of the rotating tray 24 is away from the limiting ribs 221 on the bottom cover 22 of the secondary air duct, so that the rotating tray 24 can rotate when the composite filter screen 1 is installed.

[0189] Working principle and usage process:

[0190] First, when the composite filter 1 is not installed, the highest point of the trapezoidal guide rib 51 on the top cover 5 of the composite filter is higher than the lowest point of the rotating tray 24 and higher than the top of the groove 241 on the rotating tray 24. At this time, the slot 242 of the rotating tray 24 will be stuck on the limiting rib 221 of the auxiliary air duct bottom cover 22, so that the rotating tray 24 cannot rotate when the composite filter 1 is not installed.

[0191] When the composite filter 1 is installed, the guide ribs 51 on the top cover 5 of the composite filter will be inserted into the groove 241 and lift the rotating tray 24 a certain distance, so that the slot 242 on the rotating tray 24 is away from the limiting ribs 221 on the bottom cover 22 of the secondary air duct, so that the rotating tray 24 can rotate when the composite filter 1 is installed.

[0192] Next, as the composite filter 1 rotates, the trapezoidal guide ribs 51 drive the rotating tray 24 to rotate via the grooves 241. The grooves 241 also provide a counter-fixing effect on the composite filter 1, making its rotation more stable and reliable. Furthermore, compared to rotating in a face-to-face manner, the driven-coupling rotation mechanism of this invention, composed of the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5, reduces frictional wear between the composite filter 1 and the rotating tray 24, preventing material aging and reducing noise.

[0193] In addition, since the composite filter 1 is a cylindrical hollow shape, in order to make the guide ribs 51 and the grooves 241 match more smoothly when the composite filter 1 is installed and removed, the matching structure is designed in a staggered arrangement, which can play a guiding role, so that the guide ribs 51 can match the grooves 241 smoothly during the installation and removal process.

[0194] Example 5:

[0195] Furthermore, the present invention provides an air conditioning fan including the driven engagement rotation mechanism as described above, characterized in that the driven engagement rotation mechanism is detachably disposed within the air conditioning fan.

[0196] The driven rotating mechanism inside the air conditioning fan can be found in [reference]. Figure 1 Includes: secondary air duct component 2;

[0197] Base assembly 4 is located below secondary air duct assembly 2;

[0198] The bracket assembly 3 is disposed between the secondary air duct assembly 2 and the base assembly 4, and is used to support the secondary air duct assembly 2;

[0199] The composite filter 1 is located between the secondary air duct assembly 2 and the base assembly 4 inside the bracket assembly 3, and can be installed and removed between the secondary air duct assembly 2 and the base assembly 4.

[0200] Please see Figure 1 and Figure 2 The secondary air duct assembly 2 includes a secondary air duct bottom cover 22 and a rotating tray 24 installed at the bottom of the secondary air duct bottom cover 22;

[0201] A tray mounting slot 23 is provided on the bottom cover 22 of the secondary air duct for mounting the rotating tray 24;

[0202] In addition, the secondary air duct assembly 2 also includes a secondary air duct housing 21 installed on the top of the secondary air duct bottom cover 22, and a fan blade 25 is provided inside the secondary air duct housing 21.

[0203] A composite filter top cover 5 is provided on the top of the composite filter 1. The composite filter top cover 5 has a flat annular structure.

[0204] It is worth noting that the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5 together constitute a driven rotating mechanism.

[0205] Please see Figure 3 The base assembly 4 includes a rotating base 41, a base body 42, and a motor 43, wherein:

[0206] The rotating base 41 is rotatably connected to the top of the base body 42 and is used to mount the composite filter 1.

[0207] Motor 43 is installed inside the base body 42 and is used to rotate the rotating chassis 41;

[0208] It should be noted that when working, the power is turned on and the motor 43 is started. The motor 43 can drive the rotating chassis 41 to rotate through its output shaft. During the rotation of the rotating chassis 41, since the composite filter 1 is located between the secondary air duct assembly 2 and the base assembly 4 inside the support assembly 3, the rotating chassis 41 can drive the composite filter 1 to rotate between the secondary air duct assembly 2 and the base assembly 4 inside the support assembly 3.

[0209] It is worth noting that when the composite filter 1 rotates between the secondary air duct assembly 2 and the base assembly 4 located inside the support assembly 3, the composite filter 1 can rotate more stably through the cooperation of the driven rotating mechanism composed of the secondary air duct bottom cover 22, the rotating tray 24 and the composite filter top cover 5.

[0210] Please see Figure 6 Multiple sets of guide ribs 51 of different shapes and sizes are symmetrically arranged on the top of the composite filter cover 5;

[0211] Furthermore, the multiple sets of guide ribs 51 are in a parallel state with each other;

[0212] It is worth noting that the cross-sectional shape of the guide rib 51 is trapezoidal, and the two upper corners of the trapezoid are rounded.

[0213] Please see Figure 5 Multiple sets of grooves 241 of different shapes and sizes are provided on the top of the rotating tray 24;

[0214] Among them, the number of grooves 241 and guide ribs 51 are the same and correspond one-to-one;

[0215] Furthermore, the guide rib 51 and the groove 241 can cooperate with each other.

[0216] It should be noted that the two corners at the upper end of the trapezoidal guide rib 51 are rounded to facilitate the insertion and removal of the trapezoidal guide rib 51 into the groove 241.

[0217] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 as well as Figure 6 When performing work:

[0218] First, the trapezoidal guide rib 51 is slidably inserted into the groove 241;

[0219] Next, after multiple trapezoidal guide ribs 51 are inserted into the grooves 241, when the composite filter 1 rotates, the trapezoidal guide ribs 51 can drive the rotating tray 24 to rotate through the grooves 241.

[0220] The trapezoidal guide ribs 51 and the grooves 241 are designed so that while the trapezoidal guide ribs 51 drive the rotating tray 24 to rotate through the grooves 241, the grooves 241 can also fix the composite filter 1 in the opposite direction, making the composite filter 1 more stable and reliable when rotating.

[0221] Furthermore, compared to the traditional air conditioning fan where the filter rotates in a face-to-face manner, the passive rotating mechanism of this invention, which consists of the secondary air duct bottom cover 22, the rotating tray 24, and the composite filter top cover 5, can reduce frictional wear between the composite filter 1 and the rotating tray 24, prevent material aging, and reduce noise.

[0222] Furthermore, since the composite filter 1 is a cylindrical hollow shape, in order to make the trapezoidal guide ribs 51 and the grooves 241 match more smoothly when the composite filter 1 is inserted and removed, this matching structure is designed in a staggered arrangement, which can play a guiding role, so that the guide ribs 51 can smoothly match the grooves 241 during the insertion and removal of the composite filter 1.

[0223] Further, please refer to Figure 4 and Figure 7 In the driven rotating mechanism inside the air conditioner, a slide rail 222 is provided on the bottom cover 22 of the secondary air duct located on the outer periphery of the tray mounting slot 23;

[0224] Furthermore, the outer periphery of the rotating tray 24 is rotatably fitted inside the slide rail 222;

[0225] Two limiting ribs 221 are provided inside the slide 222, and the two limiting ribs 221 are aligned.

[0226] Please see Figure 5 Two slots 242 are provided on the outer periphery of the rotating tray 24, and the two slots 242 respectively cooperate with two limiting ribs 221;

[0227] It is worth noting that the two slots 242 are aligned to ensure that they can be properly engaged with the two limiting ribs 221.

[0228] Please see Figure 8 At this time, the composite filter 1 has not yet been installed inside the bracket assembly 3 between the secondary air duct assembly 2 and the base assembly 4;

[0229] Before the composite filter 1 is assembled, that is, before the composite filter 1 is installed, in order to prevent the groove 241 of the rotating tray 24 from not being parallel to the installation direction of the trapezoidal guide rib 51 on the top cover 5 of the composite filter, so that the trapezoidal guide rib 51 on the top cover 5 of the composite filter cannot be guided into the groove 241, thus preventing the composite filter 1 from being installed, two limiting ribs 221 are designed on the bottom cover 22 of the secondary air duct, and two slots 242 are designed on the rotating tray 24.

[0230] When the driven rotating mechanism is assembled in the following state Figure 8 , Figure 10 As shown (when the composite filter 1 is not installed), the highest point of the guide rib 51 on the top cover 5 of the composite filter is higher than the lowest point of the rotating tray 24;

[0231] Furthermore, the highest point of the guide rib 51 is higher than the top of the groove 241 on the rotating tray 24;

[0232] At this time, the slot 242 of the rotating tray 24 will be locked on the limiting rib 221 of the auxiliary air duct bottom cover 22, so that the rotating tray 24 cannot rotate when the composite filter 1 is not installed.

[0233] When installing composite filter 1, the driven rotating mechanism is assembled as follows: Figure 9 , Figure 11 As shown:

[0234] The trapezoidal guide ribs 51 on the top cover 5 of the composite filter screen will lift the rotating tray 24 a certain distance, so that the slot 242 of the rotating tray 24 is away from the limiting ribs 221 on the bottom cover 22 of the secondary air duct, so that the rotating tray 24 can rotate when the composite filter screen 1 is installed.

[0235] Working principle and usage process:

[0236] First, when the composite filter 1 is not installed, the highest point of the trapezoidal guide rib 51 on the top cover 5 of the composite filter is higher than the lowest point of the rotating tray 24 and higher than the top of the groove 241 on the rotating tray 24. At this time, the slot 242 of the rotating tray 24 will be stuck on the limiting rib 221 of the auxiliary air duct bottom cover 22, so that the rotating tray 24 cannot rotate when the composite filter 1 is not installed.

[0237] When the composite filter 1 is installed, the guide ribs 51 on the top cover 5 of the composite filter will be inserted into the groove 241 and lift the rotating tray 24 a certain distance, so that the slot 242 on the rotating tray 24 is away from the limiting ribs 221 on the bottom cover 22 of the secondary air duct, so that the rotating tray 24 can rotate when the composite filter 1 is installed.

[0238] Next, as the composite filter 1 rotates, the trapezoidal guide ribs 51 drive the rotating tray 24 to rotate via the grooves 241. The grooves 241 also provide a counter-fixing effect on the composite filter 1, making its rotation more stable and reliable.
