[0025] The following detailed implementation provides a plurality of different embodiments or examples for implementing the present application. Of course, these are only examples or instances and are not intended to be limiting. In addition, repeated reference numerals may be used to indicate in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present application, and do not represent a specific relationship between the different embodiments and / or structures discussed. ​​

[0026] As Figures 1-7 The wall-mounted air purifier with intelligent advertisement projection screen includes an air purifier body 1, an air inlet 2 and an air outlet 3 are arranged on the left and right sides of the air purifier body 1 respectively, a rectangular accommodating groove 4 is arranged on the front side of the air purifier body 1, and a flat panel display machine 5 is detachably placed in the rectangular accommodating groove 4. Wherein, a left rotating shaft 6 and a right rotating shaft 7 are arranged on the left and right sides of the flat panel display machine 5 respectively, a left U-shaped ring seat 8 is arranged on the left side of the rectangular accommodating groove 4, a right U-shaped ring seat 9 is arranged on the right side of the rectangular accommodating groove 4, the left rotating shaft 6 is arranged on the two left U-shaped ring seats 8 through a detachable structure, the right rotating shaft 7 is arranged on the two right U-shaped ring seats 9 through a detachable structure, and a driving mechanism is further arranged on the air purifier body 1. The driving mechanism can drive the flat panel display machine 5 to rotate around the left rotating shaft 6 or the right rotating shaft 7 so as to be folded outward.

[0027] The wall-mounted air purifier with intelligent advertisement projection screen takes the air purifier body 1 as a core carrier when realizing the air purification function. After the equipment is started, the indoor air containing pollutants enters the inside of the air purifier under the action of the fan and other components in the air purifier body 1. The air entering the inside is filtered and purified by the filter screen (such as HEPA filter screen, activated carbon filter screen, etc., which are the standard components of conventional air purification equipment), and the particulate matters, peculiar smell, harmful gases and other pollutants in the air are effectively removed. The clean air after purification is discharged through the air outlet 3 arranged on the right side of the air purifier body 1 and returns to the indoor environment, so as to be circulated and improved continuously.

[0028] The flat panel display machine 5 is detachably placed in the rectangular accommodating groove 4 on the front side of the air purifier body 1. The flat panel display machine 5 is pre-loaded with advertisement content, information data, etc. The advertisement or information is presented through the display function of the flat panel display machine 5, so as to realize the intelligent advertisement projection screen effect and provide the surrounding personnel with the viewing.

[0029] When the display angle of the flat panel display 5 needs to be adjusted, the driving mechanism on the purifier body 1 is started. If rotation around the left rotation shaft 6 is needed, the driving mechanism will exert a driving force on the flat panel display 5, so that the flat panel display 5 is flipped outwards with the left rotation shaft 6 as the rotation center (the left rotation shaft 6 is fixed on the two left U-shaped ring seats 8 on the left side of the rectangular accommodating groove 4 through a detachable structure, and remains stable), until the target angle is adjusted, and then the driving mechanism stops working; if rotation around the right rotation shaft 7 is needed, the driving mechanism drives the flat panel display 5 to flip outwards with the right rotation shaft 7 as the rotation center (the right rotation shaft 7 is fixed on the two right U-shaped ring seats 9 on the right side of the rectangular accommodating groove 4 through a detachable structure), and the angle adjustment is completed. By rotating around different rotation shafts, multi-directional and multi-angle display angle adjustment can be realized, and the viewing requirements in different scenes can be met.

[0030] Therefore, the device has air purification and intelligent advertising projection functions at the same time, and the two functions can work independently or cooperatively. While purifying indoor air and ensuring air quality, the device can continuously conduct advertising promotion or information release without additional advertising equipment, fully utilizes the device space and function, and improves the comprehensive utilization rate of the device, which is especially suitable for commercial places (such as shopping malls and hotels) and office areas that have demands for air quality and advertising dissemination, and has high practicality and efficiency.

[0031] Referring to Figures 1-3 As shown in the figure, the detachable structure includes a magnet 21 arranged on the inner wall of the left U-shaped ring seat 8 and the right U-shaped ring seat 9, and a metal iron ring 22 that can be magnetically attracted to the magnet 21 is sleeved on the left rotation shaft 6 and the right rotation shaft 7.

[0032] When the flat panel display 5 is installed into the rectangular accommodating groove 4 of the purifier body 1, the left rotation shaft 6 and the right rotation shaft 7 on the left and right sides of the flat panel display 5 need to be aligned with the left U-shaped ring seat 8 and the right U-shaped ring seat 9 in the rectangular accommodating groove 4. Since the inner wall of the left U-shaped ring seat 8 and the right U-shaped ring seat 9 is provided with the magnet 21, and the left rotation shaft 6 and the right rotation shaft 7 are sleeved with the metal iron ring 22 that can be magnetically attracted to the magnet 21, when the left rotation shaft 6 is put into the left U-shaped ring seat 8 and the right rotation shaft 7 is put into the right U-shaped ring seat 9, the magnet 21 will generate a magnetic attraction force with the metal iron ring 22. Under the adsorption of the action force, the metal iron ring 22 will tightly adhere to the magnet 21 on the inner wall of the U-shaped ring seat, and then the left rotation shaft 6 is stably fixed in the left U-shaped ring seat 8 and the right rotation shaft 7 is stably fixed in the right U-shaped ring seat 9, completing the rapid installation of the flat panel display 5, and without the need for additional tools such as screws and buckles for locking.

[0033] 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 works when the flat panel display 5 is driven to rotate around the left rotating shaft 6 or the right rotating shaft 7 by the driving mechanism. On the one hand, the magnetic attraction force can keep the stable connection between the rotating shaft and the U-shaped ring seat, avoiding the loosening and deviation of the flat panel display 5 during the rotation, and ensuring the smooth rotation. On the other hand, the magnetic attraction force has a certain adjustability. Under the driving force of the driving mechanism, the metal ring 22 can rotate around the shaft center in the U-shaped ring seat with the rotating shaft, and the magnetic attraction force will not limit the circumferential rotation of the rotating shaft, which not only ensures the smoothness of the angle adjustment, but also can assist in fixing the position of the rotating shaft after adjusting to the target angle, reducing the angle deviation of the flat panel display 5 due to slight collision of external force.

[0034] Referring to Figures 1-3 As shown in the figure, the driving mechanism includes a sliding plate 31 sliding left and right under the lower end of the rectangular accommodating groove 4, a first rack 32 is arranged on the front side of the sliding plate 31, a left gear 33 and a right gear 34 capable of engaging with the first rack 32 are respectively arranged on the left rotating shaft 6 and the right rotating shaft 7, a vertical plate 35 is arranged on the rear side of the sliding plate 31, a limiting stop rod 36 extending in the left and right directions is arranged on the upper end of the vertical plate 35, and a sliding mechanism capable of driving the sliding plate 31 to slide left and right is further arranged on the purifier body 1. When the sliding plate 31 slides to the right, the first rack 32 engages with the right gear 34 and disengages with the left gear 33, and at the same time, the limiting stop rod 36 moves to the front side of the right rotating shaft 7 to limit the right rotating shaft 7. When the sliding plate 31 slides to the left, the first rack 32 engages with the left gear 33 and disengages with the right gear 34, and at the same time, the limiting stop rod 36 moves to the front side of the left rotating shaft 6 to limit the left rotating shaft 6.

[0035] When the flat panel display 5 needs to be folded outward around the right rotating shaft 7, the sliding mechanism on the purifier body 1 is started, and the sliding mechanism drives the sliding plate 31 at the lower end of the rectangular accommodating groove 4 to slide in the right direction. During this process, two key actions occur synchronously: The first rack 32 on the front side of the slide plate 31 moves rightward synchronously with the slide plate, and the right gear 34 on the right rotating shaft 7 gradually enters the meshing state. When the first rack 32 and the right gear 34 are stably meshed, the slide mechanism continuously drives the slide plate 31 to slide rightward, the first rack 32 drives the right gear 34 to rotate through the tooth surface transmission, the right gear 34 is fixedly connected with the right rotating shaft 7, thereby driving the right rotating shaft 7 to synchronously rotate, and finally driving the flat panel display 5 to outwardly turn out around the right rotating shaft 7 as the center until the target angle is reached. Meanwhile, the vertical plate 35 fixedly connected with the slide plate 31 on the rear side moves rightward synchronously, and the limiting stopper 36 extending along the left-right direction on the upper end of the vertical plate 35 also moves rightward, and finally moves to the position in front of the right rotating shaft 7. The limiting stopper 36 limits the right rotating shaft 7 from being forwardly deviated in the rotating process through the physical blocking action, ensures that the right rotating shaft 7 always rotates around the fixed shaft center, and avoids that the flat panel display 5 is unstable in structure or the angle adjustment is deviated due to the rotating deviation.

[0036] When it is needed to outwardly turn out the flat panel display 5 around the left rotating shaft 6, the slide plate 31 can be driven to slide leftward.

[0037] Referring to Figure 4 The slide mechanism comprises the motor 41 arranged at the bottom end of the purifier body 1, the driving gear 42 arranged on the output shaft of the motor 41, the transverse sliding groove 43 extending along the left-right direction and arranged at the lower end of the rectangular accommodating groove 4, and the second rack 44 arranged on the slide plate 31 and capable of meshing with the driving gear 42 and sliding leftward and rightward in the transverse sliding groove 43.

[0038] When it is needed to drive the flat panel display 5 to rotate around the right rotating shaft 7 or the left rotating shaft 6, the motor 41 at the bottom end of the purifier body 1 is started, the output shaft of the motor 41 drives the driving gear 42 fixedly arranged thereon to synchronously rotate, the driving gear 42 and the second rack 44 on the slide plate 31 are meshed with each other, and the rotating movement of the driving gear 42 is converted into the linear movement of the second rack 44 through the tooth surface transmission.

[0039] In addition, when it is needed to reset the flat panel display 5, the motor 41 is controlled to rotate in the opposite direction, the slide plate 31 is reversely slid through the second rack 44 and the driving gear 42, the slide plate 31 reversely drives the corresponding gear through the first rack 32, the rotating shaft is reversely rotated, the flat panel display 5 is retracted into the rectangular accommodating groove 4, and the reset operation is completed.

[0040] Referring to Figures 1-3As shown, a left support disc 51 is arranged at the upper end of the left rotating shaft 6, and when the left rotating shaft 6 is arranged on the left U-shaped ring seat 8, the left support disc 51 is supported against the upper end of the left U-shaped ring seat 8; a right support disc 52 is arranged at the upper end of the right rotating shaft 7, and when the right rotating shaft 7 is arranged on the right U-shaped ring seat 9, the right support disc 52 is supported against the upper end of the right U-shaped ring seat 9.

[0041] When the left rotating shaft 6 reaches the mounting position, the left support disc 51 at the upper end of the left rotating shaft 6 naturally abuts against and supports the upper end surface of the left U-shaped ring seat 8. Since the diameter of the left support disc 51 is greater than the diameter of the left rotating shaft 6 and greater than the width of the opening of the left U-shaped ring seat 8, the left support disc 51 limits the left rotating shaft 6 from continuing to slide downward by abutting against the upper end surface of the left U-shaped ring seat 8, thereby quickly completing the axial positioning of the left rotating shaft 6 and avoiding the collision of the rotating shaft with the bottom of the rectangular accommodating groove 4 due to the excessive deep installation or the instability of the structure due to the excessive shallow installation. Similarly, when the right rotating shaft 7 is installed, after the right rotating shaft 7 is arranged in the right U-shaped ring seat 9, the right support disc 52 at the upper end of the right rotating shaft 7 supports the upper end surface of the right U-shaped ring seat 9, thereby achieving the axial positioning of the right rotating shaft 7 by physical abutment and ensuring that the right rotating shaft 7 is installed at the preset height and horizontally aligned with the left rotating shaft 6, thereby laying a foundation for the stable installation of the flat panel display 5.

[0042] Therefore, when the flat panel display 5 is normally used or rotated around the rotating shaft to adjust the angle, the weight of the flat panel display 5 is transmitted to the left U-shaped ring seat 8 and the right U-shaped ring seat 9 through the left rotating shaft 6 and the right rotating shaft 7. At this time, the left support disc 51 continuously abuts against the upper end surface of the left U-shaped ring seat 8, thereby dispersing the axial load (the weight of the flat panel display) borne by the left rotating shaft 6 to the upper end surface of the left U-shaped ring seat 8. Similarly, the right support disc 52 disperses the axial load of the right rotating shaft 7 to the upper end surface of the right U-shaped ring seat 9, thereby achieving the bidirectional load dispersion support.

[0043] In the air purifier, a grid assembly is arranged on the air inlet 2 and the air outlet 3, wherein the grid assembly comprises a plurality of swing shafts 61 arranged at intervals in the front-rear direction, the swing shafts 61 are vertically rotatably arranged, and a blade 62 is arranged on each swing shaft 61; and a regulating mechanism for synchronously regulating the angle of all the blades 62 is further arranged on the purifier body 1.

[0044] When the air purifier is normally operated, the air inlet 2 completes the air circulation by inhaling indoor air, and the air outlet 3 discharges clean air, and at this time, the angle of the blade 62 of the grid assembly can be flexibly adjusted by the regulating mechanism.

[0045] 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.

[0046] 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.

[0047] 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".

[0048] The first adjusting plate 72 is provided with an adjusting notch 76, and the adjusting guide column 75 at the lower end of the connecting plate 74 extends through the cavity 71 and into the adjusting notch 76, when the first adjusting plate 72 slides forward and backward, the adjusting notch 76 will generate a transverse thrust on the adjusting guide column 75, driving the adjusting guide column 75 and the connecting plate 74 to move in the forward and backward directions; since the connecting plate 74 is connected with the connecting columns 73 at the lower ends of all the blades 62, the forward and backward movement of the connecting plate 74 will synchronously drive all the connecting columns 73 to move forward and backward, thereby pushing the blades 62 to rotate around the vertically arranged swing shaft 61, realizing the synchronous adjustment of the blade angle.

[0049] Therefore, the operator does not need to use tools, and only needs to move forward and backward along the guide straight groove with hands to trigger the adjustment, the operation mode is simple and intuitive, whether it is an old person, a child or an ordinary worker, it can be easily operated, the operation threshold of the equipment is greatly reduced, and it is especially suitable for scenes of non-professional operation of families and shopping malls.

[0050] In the present application, a transmission assembly is detachably connected between the poking column 711 and the sliding plate 31, when the sliding plate 31 slides left and right, the transmission assembly can drive the poking column 711 to slide forward and backward along the guide straight groove 712.

[0051] When the driving mechanism controls the flat panel display machine 5 to reciprocatingly rotate and swing, the sliding plate 31 is driven to reciprocatingly slide left and right along the lower end of the rectangular accommodating groove 4; when the flat panel display machine 5 is unfolded outward from the initial position around the right rotating shaft 7, the sliding mechanism drives the sliding plate 31 to slide right; when the flat panel display machine 5 is reset from the right unfolded position and unfolded outward around the left rotating shaft 6, the sliding mechanism drives the sliding plate 31 to slide left; if the reciprocating rotation and swing need to be realized (such as being circulated between the maximum angle of right unfolding and the maximum angle of left unfolding), the sliding mechanism drives the sliding plate 31 to continuously reciprocatingly slide in the left and right directions, forming a circulating movement of “right slide→left slide→right slide”.

[0052] The transmission assembly detachably connected with the sliding plate 31 and the poking column 711 will synchronously respond to the reciprocating sliding of the sliding plate 31. When the sliding plate 31 slides, the transmission assembly drives the poking column 711 to slide along the guide straight groove 712 through mechanical linkage. With the continuous left and right reciprocating sliding of the sliding plate 31, the poking column 711 forms a reciprocating movement of “forward→backward→forward” in the guide straight groove 712, and the movement frequency is consistent with the reciprocating sliding frequency of the sliding plate 31, ensuring that the two movements are synchronous.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] In the present application, the protective cover (not shown in the drawings) is installed at the bottom end of the purifier body 1. After covering the protective cover, foreign matters such as dust, hair, debris, liquid (such as water, beverage spatter) and the like from the outside can be blocked from entering the inside of the bottom end of the purifier, so as to avoid the foreign matters from falling into the cavity 71 to block the transmission gap of the adjusting mechanism, prevent the foreign matters from winding and stirring the column 711 or the sliding of the slide plate 31, ensure that the driving mechanism, transmission assembly, adjusting mechanism and the like are always in a clean running environment, and avoid mechanical failure caused by foreign matters.

[0058] Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments and the description in the specification, which only illustrate the principles of the present application, and that various changes and improvements can be made to the present application without departing from the spirit and scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
