Description

Technical Field

[0001] This invention relates to the field of air purifier technology, and in particular to a wall-mounted air purifier with intelligent advertising projection. Background Technology

[0002] With the improvement of people's living standards and the increasing emphasis on indoor air quality, air purifiers have become widely used devices in various scenarios such as homes, offices, and commercial spaces. Traditional wall-mounted air purifiers mainly focus on air purification, drawing in indoor air through the air inlet, filtering and purifying it through the internal filter, and then expelling clean air from the air outlet, thereby improving indoor air quality.

[0003] However, in today's diversified demand environment, a single air purification function is no longer sufficient to meet users' comprehensive needs. In commercial spaces such as shopping malls, hotel lobbies, and office building corridors, in addition to air quality requirements, advertising and information dissemination activities are often necessary. Currently, these venues typically require separate installations of air purifiers and independent advertising placement equipment (such as advertising screens and poster stands). This separate setup presents several problems: firstly, it occupies more space, especially in areas with limited space, where multiple devices can make the environment appear crowded and cluttered, affecting the overall aesthetics; secondly, separately purchasing, installing, and maintaining air purifiers and advertising placement equipment increases users' procurement, installation, and subsequent maintenance costs, and is also more cumbersome to operate, hindering efficient management and use of the equipment. 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 wall-mounted air purifier with intelligent advertising projection.

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

[0006] A wall-mounted air purifier with intelligent advertising projection includes a purifier body, with an air inlet and an air outlet on the left and right sides of the purifier body, respectively. A rectangular receiving slot is provided on the front side of the purifier body, and a flat panel display is detachably placed in the rectangular receiving slot. A vertically arranged left rotation axis and a right rotation axis are provided on the left and right sides of the flat panel display, respectively. A left U-shaped ring seat is spaced vertically on the left side of the rectangular receiving slot, and a right U-shaped ring seat is spaced vertically on the right side. The left rotation axis is detachably mounted on the two left U-shaped ring seats, and the right rotation axis is detachably mounted on the two right U-shaped ring seats. A driving mechanism is also provided on the purifier body, which can drive the flat panel display to rotate around the left or right rotation axis and thus flip outward.

[0007] In some embodiments, the detachable structure includes magnets disposed on the inner walls of the left U-shaped ring seat and the right U-shaped ring seat, and metal iron rings that are magnetically attracted to the magnets are sleeved on both the left and right rotation shafts.

[0008] In some embodiments, the driving mechanism includes a slide plate that slides left and right on the lower end of the rectangular receiving groove. A first rack is provided on the front side of the slide plate. A left gear and a right gear that can mesh with the first rack are respectively provided on the left and right rotation axes. A vertical plate is provided on the rear side of the slide plate. A limiting stop bar extending in the left and right direction is provided on the upper end of the vertical plate. A sliding mechanism that can drive the slide plate to slide left and right is also provided on the purifier body. When the slide plate slides to the right, the first rack meshes with the right gear and disengages from the left gear. At the same time, the limiting stop bar moves to the front side of the right rotation axis to limit the right rotation axis. When the slide plate slides to the left, the first rack meshes with the left gear and disengages from the right gear. At the same time, the limiting stop bar moves to the front side of the left rotation axis to limit the left rotation axis.

[0009] In some embodiments, the sliding mechanism includes a motor disposed at the bottom end of the purifier body, a drive gear disposed on the output shaft of the motor, a transverse sliding groove extending in the left-right direction through the lower end of the rectangular receiving groove, and a second rack that can mesh with the drive gear sliding left and right on the sliding plate and within the transverse sliding groove.

[0010] In some embodiments, a left support disk is provided at the upper end of the left rotation shaft. When the left rotation shaft is located on the left U-shaped ring seat, the left support disk supports and abuts against the upper end of the left U-shaped ring seat. A right support disk is provided at the upper end of the right rotation shaft. When the right rotation shaft is located on the right U-shaped ring seat, the right support disk supports and abuts against the upper end of the right U-shaped ring seat.

[0011] In some embodiments, a grid assembly is provided on both the air inlet and the air outlet. The grid assembly includes a plurality of swing shafts spaced apart in the front-to-back direction. The swing shafts are vertically rotatable and have blades on them. An adjustment mechanism capable of synchronously adjusting the angle of all blades is also provided on the purifier body.

[0012] In some embodiments, a cavity is provided at the bottom of the purifier body, below the air inlet and air outlet. The adjustment mechanism includes a first adjustment plate disposed in the cavity and sliding in the front-back direction. A connecting post is provided at the lower end of each blade. A connecting plate is connected to the lower end of all the connecting posts. The connecting plate is movable back and forth. An adjustment guide post is provided at the lower end of the connecting plate. An adjustment slot is provided on the first adjustment plate. The lower end of the adjustment guide post moves through the cavity and extends into the adjustment slot. A third rack is provided on one side of the first adjustment plate. A double gear that can mesh with the third rack is rotatably installed in the cavity. A second adjustment plate also slides back and forth in the cavity. A fourth rack that can mesh with the double gear is also provided on the second adjustment plate. A toggle post is provided at the lower end of the second adjustment plate. A guide groove extending in the front-back direction passes through the lower end of the cavity. The toggle post slides back and forth in the guide groove.

[0013] In some embodiments, a transmission component is detachably connected between the actuating post and the sliding plate. When the sliding plate slides left and right, the transmission component can drive the actuating post to slide back and forth along the guide groove.

[0014] In some embodiments, the transmission assembly includes a fixed plate disposed on the slide plate, a transmission plate detachably connected to the fixed plate by a pin, a transmission groove provided on the transmission plate, and the actuating column passing through the guide groove and the transmission groove in sequence.

[0015] In some embodiments, a protective cover is installed at the bottom of the purifier body.

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

[0017] 1. This wall-mounted air purifier with intelligent advertising projection organically combines air purification and intelligent advertising projection functions, eliminating the need for separate air purifiers and independent advertising projection equipment. This effectively saves installation space and creates a cleaner, more aesthetically pleasing installation environment. Furthermore, users do not need to purchase two separate devices, reducing procurement costs. In subsequent use, only one device needs maintenance, reducing maintenance costs and operational complexity, and facilitating efficient device management for users.

[0018] 2. The flat panel display is connected to the left and right U-shaped ring seats within a rectangular receiving slot via left and right rotation axes. Driven by the drive mechanism, it can rotate around the left or right rotation axis to flip outwards. Users can flexibly adjust the display angle of the flat panel display according to actual usage scenarios and viewing needs, ensuring that users can clearly view advertising content or obtain relevant information from different positions and viewing angles. This significantly improves advertising dissemination effectiveness and information acquisition efficiency, meeting diverse usage needs.

[0019] 3. In addition to its core air purification function, this device adds intelligent advertising projection capabilities, enriching its functionality and expanding its application scenarios. It can be used not only in homes and ordinary offices but also better meet the needs of commercial venues such as shopping malls, hotels, and office buildings. Furthermore, the adjustable display angle and detachable structure further enhance the device's practicality and user experience, giving it a competitive edge in the market and facilitating its promotion and widespread adoption.

[0027] 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.

[0028] like Figures 1-7 The wall-mounted air purifier with intelligent advertising projection shown includes a purifier body 1. An air inlet 2 and an air outlet 3 are respectively provided on the left and right sides of the purifier body 1. A rectangular receiving slot 4 is provided on the front side of the purifier body 1, and a flat panel display 5 is detachably placed in the rectangular receiving slot 4. A vertically arranged left rotation shaft 6 and a right rotation shaft 7 are respectively provided on the left and right sides of the flat panel display 5. A left U-shaped ring seat 8 is spaced vertically on the left side of the rectangular receiving slot 4, and a right U-shaped ring seat 9 is spaced vertically on the right side. The left rotation shaft 6 is detachably mounted on the two left U-shaped ring seats 8, and the right rotation shaft 7 is detachably mounted on the two right U-shaped ring seats 9. A driving mechanism is also provided on the purifier body 1, which can drive the flat panel display 5 to rotate around the left rotation shaft 6 or the right rotation shaft 7, thereby flipping it outwards.

[0029] This wall-mounted air purifier with intelligent advertising projection uses the purifier body 1 as its core component to achieve air purification. After the device is turned on, indoor air containing pollutants enters the purifier body 1 through the air inlet 2 located on the left side, driven by components such as the fan. The incoming air is then filtered and purified by filters (such as HEPA filters and activated carbon filters, standard components in conventional air purifiers), effectively removing particulate matter, odors, and harmful gases. The purified air is then exhausted through the air outlet 3 located on the right side of the purifier body 1, returning to the indoor environment. This cycle continues, continuously improving indoor air quality.

[0030] The flat panel display 5 can be detached and placed in the rectangular receiving slot 4 on the front side of the purifier body 1. The flat panel display 5 is preloaded with advertising content, information data, etc., and displays the advertisements or information through its own display function to achieve the effect of intelligent advertising projection for people around to watch.

[0031] When the display angle of the flat panel display 5 needs to be adjusted, the drive mechanism on the purifier body 1 is activated. If rotation around the left rotation axis 6 is required, the drive mechanism applies a driving force to the flat panel display 5, causing it to flip outwards around the left rotation axis 6 (which is detachably fixed to the two left U-shaped ring seats 8 on the left side of the rectangular receiving groove 4 for stability) until the target angle is reached, at which point the drive mechanism stops working. If rotation around the right rotation axis 7 is required, the drive mechanism drives the flat panel display 5 to flip outwards around the right rotation axis 7 (which is detachably fixed to the two right U-shaped ring seats 9 on the right side of the rectangular receiving groove 4) to complete the angle adjustment. By rotating around different rotation axes, multi-directional and multi-angle display angle adjustments can be achieved to meet viewing needs in different scenarios.

[0032] Therefore, this device simultaneously possesses air purification and intelligent advertising projection functions, which can work independently or in conjunction. While purifying indoor air and ensuring air quality, it can continuously conduct advertising or information dissemination without the need for additional advertising equipment. It makes full use of the device's space and functions, improving the overall utilization rate of the device. It is especially suitable for commercial venues (such as shopping malls and hotels) and office areas that have both air quality and advertising dissemination requirements, demonstrating significant practicality and efficiency.

[0033] See Figures 1-3 As shown, the detachable structure includes magnets 21 disposed on the inner walls of the left U-shaped ring seat 8 and the right U-shaped ring seat 9, and metal iron rings 22 that are magnetically attracted to the magnets 21 are sleeved on the left rotating shaft 6 and the right rotating shaft 7.

[0034] When installing the flat panel display 5 into the rectangular receiving slot 4 of the purifier body 1, the left rotating shaft 6 and right rotating shaft 7 on the left and right sides of the flat panel display 5 should be aligned with the left U-shaped ring seat 8 and right U-shaped ring seat 9 inside the rectangular receiving slot 4. Since magnets 21 are provided on the inner walls of the left U-shaped ring seat 8 and right U-shaped ring seat 9, and metal rings 22 that can be magnetically attracted to the magnets 21 are fitted on the left rotating shaft 6 and right rotating shaft 7, when the left rotating shaft 6 is placed into the left U-shaped ring seat 8 and the right rotating shaft 7 into the right U-shaped ring seat 9, the magnets 21 will generate a magnetic attraction force with the metal rings 22. Under the attraction of this force, the metal rings 22 will tightly adhere to the magnets 21 on the inner wall of the U-shaped ring seat, thereby stably fixing the left rotating shaft 6 in the left U-shaped ring seat 8 and the right rotating shaft 7 in the right U-shaped ring seat 9, completing the quick installation of the flat panel display 5 without the need for additional screws, clips, or other tools for locking.

[0035] When the angle of the flat panel display 5 needs to be adjusted, the magnetic attraction between the magnet 21 and the metal ring 22 still functions when the flat panel display 5 is driven to rotate around the left rotation axis 6 or the right rotation axis 7 by the drive mechanism. On the one hand, the magnetic attraction force can maintain a stable connection between the rotating axis and the U-shaped ring seat, preventing the flat panel display 5 from becoming loose or shifting during rotation, and ensuring a smooth rotation process. On the other hand, since the magnetic attraction force has a certain degree of adjustability, under the driving force of the drive mechanism, the metal ring 22 can rotate around the axis within the U-shaped ring seat with the rotating axis. The magnetic attraction force does not restrict the circumferential rotation of the rotating axis, which not only ensures the smoothness of angle adjustment, but also helps to fix the position of the rotating axis after adjustment to the target angle, reducing the possibility of angle shift of the flat panel display 5 due to slight external impacts.

[0036] See Figures 1-3 As shown, the driving mechanism includes a sliding plate 31 that slides left and right at the lower end of the rectangular receiving groove 4. A first rack 32 is provided on the front side of the sliding plate 31. A left gear 33 and a right gear 34 that can mesh with the first rack 32 are respectively provided on the left rotation shaft 6 and the right rotation shaft 7. A vertical plate 35 is provided on the rear side of the sliding plate 31. A limiting stop bar 36 extending in the left and right direction is provided on the upper end of the vertical plate 35. A sliding mechanism that can drive the sliding plate 31 to slide left and right is also provided on the purifier body 1. When the sliding plate 31 slides to the right, the first rack 32 meshes with the right gear 34 and disengages from the left gear 33. At the same time, the limiting stop bar 36 moves to the front side of the right rotation shaft 7 to limit the right rotation shaft 7. When the sliding plate 31 slides to the left, the first rack 32 meshes with the left gear 33 and disengages from the right gear 34. At the same time, the limiting stop bar 36 moves to the front side of the left rotation shaft 6 to limit the left rotation shaft 6.

[0037] When the flat panel display 5 needs to be flipped outward around the right rotation axis 7, the sliding mechanism on the purifier body 1 is activated. The sliding mechanism drives the slide plate 31 at the lower end of the rectangular receiving slot 4 to slide to the right. During this process, two key actions occur simultaneously:

[0038] The first rack 32 on the front side of the slide plate 31 moves synchronously to the right with the slide plate, and the right gear 34 on the right rotating shaft 7 gradually engages. After the first rack 32 and the right gear 34 are stably engaged, the sliding mechanism continues to drive the slide plate 31 to slide to the right. The first rack 32 drives the right gear 34 to rotate through tooth surface transmission. The right gear 34 is fixedly connected to the right rotating shaft 7, thereby driving the right rotating shaft 7 to rotate synchronously. Finally, the flat panel display 5 is driven to flip outward around the right rotating shaft 7 until the target angle is reached. At the same time, the upright plate 35, which is fixedly connected to the rear side of the slide plate 31, moves synchronously to the right with the slide plate. The limiting stop 36, which extends from the upper end of the upright plate 35 in the left-right direction, also moves to the right and eventually moves to the front side of the right rotating shaft 7. The limiting stop 36, through physical blocking, restricts the right rotating shaft 7 from shifting forward during rotation, ensuring that the right rotating shaft 7 always rotates around a fixed axis, and preventing the flat panel display 5 from becoming unstable or having an angle adjustment deviation due to rotational deviation.

[0039] When the flat panel display 5 needs to be flipped outward around the left rotation axis 6, the working principle is the same as that around the right rotation axis 7, and the sliding plate 31 can be driven to slide in the left direction.

[0040] See Figure 4 As shown, the sliding mechanism includes a motor 41 located at the bottom of the purifier body 1, a drive gear 42 on the output shaft of the motor 41, a transverse sliding groove 43 extending in the left and right direction through the lower end of the rectangular receiving groove 4, and a second rack 44 that can mesh with the drive gear 42 sliding left and right on the slide plate 31 and located in the transverse sliding groove 43.

[0041] When it is necessary to drive the flat panel display 5 to rotate around the right rotation axis 7 or the left rotation axis 6, the motor 41 at the bottom of the purifier body 1 is started. The output shaft of the motor 41 drives the drive gear 42 fixed on it to rotate synchronously. Since the drive gear 42 meshes with the second rack 44 on the slide plate 31, the rotational motion of the drive gear 42 is converted into the linear motion of the second rack 44 through tooth surface transmission.

[0042] In addition, when the flat panel display 5 needs to be reset, simply control the motor 41 to rotate in the opposite direction, drive the gear 42 to drive the slide plate 31 to slide in the opposite direction through the second rack 44, and the slide plate 31 drives the first rack 32 to drive the corresponding gear in the opposite direction, so that the rotating shaft rotates in the opposite direction, and the flat panel display 5 is returned to the rectangular receiving slot 4 to complete the reset operation.

[0043] See Figure 1-3As shown, a left support disk 51 is provided at the upper end of the left rotating shaft 6. When the left rotating shaft 6 is located on the left U-shaped ring seat 8, the left support disk 51 supports and abuts against the upper end of the left U-shaped ring seat 8. A right support disk 52 is provided at the upper end of the right rotating shaft 7. When the right rotating shaft 7 is located on the right U-shaped ring seat 9, the right support disk 52 supports and abuts against the upper end of the right U-shaped ring seat 9.

[0044] Once the left rotating shaft 6 reaches its installation position, its upper left support disc 51 will naturally abut against the upper surface of the left U-shaped ring seat 8. Since the diameter of the left support disc 51 is larger than the diameter of the left rotating shaft 6 and the width of the opening of the left U-shaped ring seat 8, the left support disc 51, by abutting against the upper surface of the left U-shaped ring seat 8, restricts the left rotating shaft 6 from sliding further downwards, quickly completing the axial positioning of the left rotating shaft 6. This avoids collisions between the rotating shaft and the bottom of the rectangular receiving groove 4 due to excessive installation depth, or structural instability due to insufficient installation depth. Similarly, when installing the right rotating shaft 7, after the right rotating shaft 7 is placed into the right U-shaped ring seat 9, its upper right support disc 52 will abut against the upper surface of the right U-shaped ring seat 9. This physical abutment achieves axial positioning of the right rotating shaft 7, ensuring that the right rotating shaft 7 is installed at a preset height and horizontally aligned with the left rotating shaft 6, laying the foundation for the stable installation of the flat panel display 5.

[0045] Therefore, when the flat panel display 5 is in normal use or rotating around the rotation axis to adjust its angle, the weight of the flat panel display 5 itself will be transmitted to the left U-shaped ring seat 8 and the right U-shaped ring seat 9 through the left rotation axis 6 and the right rotation axis 7. At this time, the left support disk 51 continuously abuts against the upper surface of the left U-shaped ring seat 8, distributing the axial load (the weight of the flat panel display) borne by the left rotation axis 6 to the upper surface of the left U-shaped ring seat 8. Similarly, the right support disk 52 distributes the axial load of the right rotation axis 7 to the upper surface of the right U-shaped ring seat 9, achieving bidirectional load distribution support.

[0046] In this invention, a grid assembly is provided on both the air inlet 2 and the air outlet 3. The grid assembly includes a plurality of swing shafts 61 spaced apart along the front-back direction. The swing shafts 61 are vertically rotatable and blades 62 are provided on the swing shafts 61. An adjustment mechanism that can synchronously adjust the angle of all blades 62 is also provided on the purifier body 1.

[0047] When the air purifier is running normally, the air inlet 2 draws in indoor air and the air outlet 3 discharges clean air to complete the air circulation. At this time, the angle of the blades 62 of the grid assembly can be flexibly adjusted by the adjustment mechanism.

[0048] Specifically, the swing shaft 61 is driven to rotate around the vertical axis, thereby changing the tilt angle of the blade 62. By adjusting the tilt direction of the blade 62, the airflow direction can be guided.

[0049] See Figure 5 , Figure 7 As shown, a cavity 71 is provided at the bottom of the purifier body 1, below the air inlet 2 and the air outlet 3. The adjustment mechanism includes a first adjustment plate 72 disposed within the cavity 71 and sliding in the front-back direction. A connecting post 73 is provided at the lower end of each blade 62. A connecting plate 74 is connected to the lower end of all the connecting posts 73. The connecting plate 74 can move back and forth, and an adjustment guide post 75 is provided at the lower end of the connecting plate 74. An adjustment slot 76 is provided on the first adjustment plate 72. The lower end of the adjustment guide post 75 moves through the cavity 71 and extends... A third rack 77 is provided on one side of the first adjusting plate 72 within the adjusting slot 76. A double gear 78 that can mesh with the third rack 77 is rotatably installed in the cavity 71. A second adjusting plate 79 is also slidably positioned back and forth within the cavity 71. A fourth rack 710 that can mesh with the double gear 78 is also provided on the second adjusting plate 79. An actuating post 711 is provided at the lower end of the second adjusting plate 79. A guide groove 712 extending in the front-back direction passes through the lower end of the cavity 71. The actuating post 711 is slidably positioned back and forth within the guide groove 712.

[0050] When it is necessary to adjust the blade angle 62 of the air inlet 2 grid assembly, the operator manually moves the actuating column 711 back and forth along the guide groove 712 at the lower end of the cavity 71. Since the actuating column 711 is fixedly connected to the lower end of the second adjusting plate 79, and the guide groove 712 directionally restricts the sliding direction of the actuating column 711, the actuating column 711 will drive the second adjusting plate 79 to slide stably in the back-and-forth direction within the cavity 71. The second adjusting plate 79 is provided with a fourth rack 710, and the fourth rack 710 meshes with a double gear 78 rotatably mounted inside the cavity 71. When the second adjusting plate 79 slides back and forth, the fourth rack 710 drives the double gear 78 to rotate around its own rotation axis through tooth surface transmission. At the same time, the double gear 78 also meshes with the third rack 77 on one side of the first adjusting plate 72. Since the rotation direction of the double gear 78 is fixed, it will drive the third rack 77 and the first adjusting plate 72 to slide in the back and forth direction through tooth surface transmission. The sliding direction of the first adjusting plate is opposite to that of the second adjusting plate 79, forming a power transmission link of "second adjusting plate sliding → double gear rotating → first adjusting plate sliding in the opposite direction".

[0051] The first adjusting plate 72 is provided with an adjusting slot 76. The adjusting guide post 75 at the lower end of the connecting plate 74 extends through the cavity 71 into the adjusting slot 76. When the first adjusting plate 72 slides back and forth, the adjusting slot 76 will generate a lateral thrust on the adjusting guide post 75, causing the adjusting guide post 75 and the connecting plate 74 to move in the front and back direction. Since the connecting plate 74 is connected to the connecting post 73 at the lower end of all blades 62, the front and back movement of the connecting plate 74 will synchronously drive all connecting posts 73 to move back and forth, thereby pushing the blades 62 to rotate around the vertically set swing axis 61, realizing the synchronous adjustment of the blade angle.

[0052] Therefore, operators do not need to use tools; they can simply move the guide groove back and forth by hand to trigger the adjustment. The operation is simple and intuitive, and can be easily used by the elderly, children, and ordinary workers, greatly reducing the operating threshold of the equipment. It is especially suitable for non-professionals to operate in scenarios such as homes and shopping malls.

[0053] In this invention, a transmission assembly is detachably connected between the actuating post 711 and the sliding plate 31. When the sliding plate 31 slides left and right, the actuating post 711 can be driven to slide back and forth along the guide groove 712 through the transmission assembly.

[0054] When the drive mechanism controls the flat panel display 5 to reciprocate and rotate, it will drive the slide plate 31 to slide back and forth along the lower end of the rectangular receiving groove 4. When the flat panel display 5 flips outward from the initial position around the right rotation axis 7, the sliding mechanism drives the slide plate 31 to slide to the right. When the flat panel display 5 returns to the right position and flips outward around the left rotation axis 6, the sliding mechanism drives the slide plate 31 to slide to the left. If it is necessary to achieve reciprocating rotation and swing (such as cycling between the maximum right flip angle and the maximum left flip angle), the sliding mechanism will drive the slide plate 31 to continuously slide back and forth in the left and right directions, forming a cyclical motion of "right slide → left slide → right slide".

[0055] The transmission assembly, detachably connected to the slide plate 31 and the actuating post 711, responds synchronously to the reciprocating sliding of the slide plate 31. When the slide plate 31 slides, the transmission assembly drives the actuating post 711 to slide along the guide groove 712 via mechanical linkage. As the slide plate 31 continues to slide left and right, the actuating post 711 forms a "forward → backward → forward" reciprocating movement within the guide groove 712, and the movement frequency is consistent with the reciprocating sliding frequency of the slide plate 31, ensuring that the two movements are synchronized.

[0056] Therefore, the reciprocating rotation of the flat panel display 5 expands the advertising visibility range, attracting viewers from more directions; while the synchronous reciprocating oscillation of the blades 62 expands the coverage of clean air. Through the reciprocating oscillation of the blades, clean air can circulate and diffuse in the left and right directions, avoiding airflow concentration in a single area and improving the overall uniformity of indoor air purification. The simultaneous operation of both achieves a dual improvement in expanding the advertising coverage and air purification range, maximizing the practical value of the equipment in commercial scenarios.

[0057] Further, see Figure 6 , Figure 7 As shown, the transmission assembly includes a fixed plate 91 disposed on the slide plate 31, a transmission plate 93 detachably connected to the fixed plate 91 by a pin 92, a transmission groove 94 disposed on the transmission plate 93, and the actuating column 711 passing through the guide straight groove 712 and the transmission groove 94 in sequence.

[0058] When achieving functional linkage, the transmission plate 93 is first detachably connected to the fixing plate 91 on the slide plate 31 via the pin 92. The connecting end of the transmission plate 93 is aligned with the fixing plate 91, ensuring their pin holes overlap. The pin 92 is then inserted into the pin hole to fix the transmission plate 93 to the fixing plate 91, thus connecting the transmission assembly to the slide plate 31. At this time, the actuating column 711 needs to pass sequentially through the guide straight groove 712 at the lower end of the cavity 71 and the transmission inclined groove 94 on the transmission plate 93, allowing the actuating column 711 to slide freely within both grooves. The guide straight groove 712 restricts the actuating column 711 to move only in the forward and backward direction, while the transmission inclined groove 94, through its tilt angle design, converts the left and right movement of the slide plate 31 into a pushing or pulling force on the actuating column 711. When the drive mechanism drives the slide plate 31 to slide, the slide plate 31 drives the transmission plate 93 to move synchronously via the fixing plate 91. Because the transmission sloping groove 94 is inclined, and the actuating column 711 is restricted by the guide straight groove 712 and cannot move left or right with the transmission plate 93, the groove wall of the transmission sloping groove 94 will generate a thrust on the actuating column 711 along the inclination direction of the groove. This thrust can be decomposed into an effective component in the front-back direction, pushing the actuating column 711 to slide along the guide straight groove 712 in the preset direction. Subsequently, the actuating column 711 drives the second adjusting plate 79 to move forward, triggering the adjustment mechanism to act, and finally causing the blade 62 to swing, thereby adjusting the airflow direction.

[0059] When no functional linkage is required, the pin 92 can be pulled out to remove the transmission plate 93 from the fixed plate 91, disconnecting the transmission assembly from the slide plate 31. At this time, the left and right sliding of the slide plate 31 no longer affects the actuation column 711, and the operator can directly manually move the actuation column 711 along the guide groove 712 to independently adjust the blade angle and flexibly switch the working mode of the equipment.

[0060] In this invention, a protective cover (not shown in the attached drawings) is installed at the bottom of the purifier body 1. After the protective cover is installed, it can prevent foreign objects such as dust, hair, debris, and liquids (such as water or beverage spills) from entering the bottom of the purifier. This prevents foreign objects from falling into the cavity 71 and blocking the transmission gap of the adjustment mechanism, and prevents foreign objects from getting entangled in the actuating column 711 or jamming the sliding plate 31. This ensures that the drive mechanism, transmission components, adjustment mechanism, and other components are always in a clean operating environment, and avoids mechanical failures caused by foreign objects.
