Description

Technical Field

[0001] The present invention relates to the technical field of air purification and humidification, and in particular to an air purification and humidification device and an air purification and humidification method. Background Art

[0002] A humidifying air purifier, also known as a freshener, is a product that combines humidification and purification. While purifying the air, it can also humidify the air, making the ambient air fresher and more comfortable. Currently, humidifying air purifiers on the market generally achieve air humidification through a wet curtain assembly installed at the air outlet. Specifically, the bottom of the wet curtain assembly is immersed in water in a water tank to absorb moisture. The wet curtain assembly is then controlled to rotate so that the entire wet curtain is filled with water. The fan then supplies air, and the air discharged through the air outlet passes through the wet curtain, causing the moisture to evaporate and achieve the humidification effect.

[0003] Most of the existing wet curtain assemblies of humidifying air purifiers are sealed at the air outlet and fixed. When the purification mode is started alone, the wet curtain assembly is still sealed at the air outlet, which will occupy a large part of the air outlet area of ​​the air outlet, resulting in too small air volume, loud noise and unclear purification effect when the user uses the purification mode alone. In addition, the wind flowing through the wet curtain will also cause certain damage to the wet curtain, accelerate the aging of the wet curtain, and affect the service life of the wet curtain.

[0044] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0045] Example 1

[0046] like Figures 1 to 13 As shown, this embodiment provides an air purification and humidification device, which includes an air duct housing 1, a humidifying mechanism 2 and a driving mechanism 3. The air duct housing 1 has an air inlet 101, an air outlet 102 and a purification air duct arranged between the air inlet 101 and the air outlet 102. A fan is provided in the purification air duct, wherein the fan can drive the air inhaled by the air inlet 101 to be discharged from the air outlet 102 along the path of the purification air duct to the external environment. A purification structure for purifying the air is provided in the purification air duct. The humidifying mechanism 2 includes a wet curtain assembly 21 arranged at the air outlet 102, and the wet curtain assembly 21 is suitable for moving between a blocking position for blocking the air outlet 102 and a avoidance position for avoiding opening the air outlet 102. The driving mechanism 3 is connected to the wet curtain assembly 21 and is suitable for driving the wet curtain assembly 21 to switch between the blocking position and the avoidance position. When the wet curtain assembly 21 is in the blocking position, the air discharged from the air outlet 102 is humidified by the wet curtain assembly 21 and then discharged to the outside of the machine to achieve the purpose of humidification. When the wet curtain assembly 21 is in the avoidance position, the purified air is directly discharged to the outside of the machine through the air outlet 102 to achieve the purpose of separate air purification.

[0047] In the above scheme, when the humidification mode of the air purification and humidification device is turned on, the driving mechanism 3 controls the wet curtain assembly 21 to remain in the blocking position, and the air discharged from the air outlet 102 is humidified by the wet curtain assembly 21 and then discharged outside the machine, thereby achieving the purpose of humidifying the air. When the purification mode of the air purification and humidification device is turned on alone, the driving mechanism 3 controls the wet curtain assembly 21 to switch to the avoidance position. When the wet curtain assembly 21 is in the avoidance position, it can avoid the air outlet 102, thereby increasing the air outlet area of ​​the air outlet 102. The purified air can be discharged directly from the air outlet 102 to the external environment without passing through the wet curtain assembly 21, thereby avoiding the problem of large wind flow resistance caused by the wet curtain assembly 21 blocking the air outlet 102, thereby increasing the air volume in the purification mode alone, reducing noise, and improving the purification effect. At the same time, it also reduces the loss of wind on the wet curtain 212 when the purification mode is used alone, thereby extending the service life of the wet curtain 212.

[0048] It should be noted that, in this embodiment, when the wet curtain assembly 21 is in the avoidance position, it can completely avoid the air outlet 102, which can be understood as the air outlet 102 is completely exposed; or when the wet curtain assembly 21 is in the avoidance position, it can avoid part of the air outlet 102, which can be understood as exposing a portion of the air outlet 102. Preferably, in this embodiment, when the wet curtain assembly 21 is in the avoidance position, the air outlet 102 is completely exposed, thereby maximizing the air outlet area and increasing the air volume.

[0049] Preferably, in this embodiment, while maximizing the air outlet area of ​​the air outlet 102 during the separate purification function, the volume of the overall structure is reduced and the space utilization rate is improved. In this embodiment, the wet curtain assembly 21 is flipped and arranged on the outside of the air outlet 102. When the humidification mode is started, the drive mechanism 3 controls the wet curtain assembly 21 to be in a blocking position relative to the air outlet 102. When the separate purification mode is started, the drive mechanism 3 controls the wet curtain assembly 21 to flip in the direction away from the air outlet 102 to open the air outlet 102. The wet curtain assembly 21 flips between the blocking position and the avoidance position to achieve blocking and opening of the air outlet 102, does not take up too much space, and improves space utilization rate.

[0050] In some embodiments, the air outlet 102 is provided on the side of the air duct housing 1, and the wet curtain assembly 21 is movably provided on the outside of the air duct housing 1 corresponding to the air outlet 102. The wet curtain assembly 21 can flip between a blocking position for blocking the air outlet 102 and a avoiding position for avoiding the air outlet 102. A rotating shaft 210 is provided at the center of the wet curtain assembly 21. When the humidification mode is activated, the wet curtain assembly 21 can rotate around the rotating shaft 210 to achieve overall uniform humidification and improve the humidification amount. The driving mechanism 3 includes a driving component 31 and a telescopic component 32. One end of the telescopic component 32 is in transmission engagement with the driving component 31, and the other end is rotatably limitedly engaged with the rotating shaft 210 of the wet curtain assembly 21. The driving component 31 is adapted to push and pull the wet curtain assembly 21 by controlling the telescopic component 32 to extend and retract, so that the wet curtain assembly 21 moves toward or away from the air outlet 102 to block or open the air outlet 102. When the separate purification mode is started, the driving component 31 controls the telescopic component 32 to extend or retract, so that the wet curtain assembly 21 flips in the direction away from the air outlet 102, so that the wet curtain assembly 21 and the air outlet 102 are opened at a set angle, and the air can be discharged directly from the air outlet 102 to the external environment.

[0051] In some implementations of this embodiment, the humidifying mechanism 2 further includes a water tank 22 and a movable support 221. The water tank 22 is disposed on a side adjacent to the air outlet 102, and the wet curtain assembly 21 is adapted to be rotatably disposed above the water tank 22 about a rotation axis 210. The movable support 221 is hinged at one end to the water tank 22, and rotatably supported and engaged with one end of the rotation axis 210 at the other end. A telescopic member 32 is rotatably engaged with the other end of the rotation axis 210. The telescopic member 32 is adapted to telescope up and down under the drive of the driving member 31, pushing and pulling the wet curtain assembly 21, causing the wet curtain assembly 21 to flip toward or away from the air outlet 102, with the hinge point between the movable support 221 and the water tank 22 serving as the pivot point, thereby blocking or opening the air outlet 102. The two ends of the rotating shaft 210 are rotatably supported and matched with the movable support member 221 and the telescopic member 32, respectively, so that in the humidification mode, the wet curtain assembly 21 can rotate around its own rotating shaft 210 under the drive of the rotary drive assembly to achieve the purpose of humidification. On the one hand, the movable support member 221 can rotatably support the wet curtain assembly 21, so that the wet curtain assembly 21 can rotate around its own rotating shaft 210 under the drive of the rotary drive assembly. On the other hand, it can also realize the movable connection between the wet curtain assembly 21 and the water tank 22, so that in the purification mode, the wet curtain assembly 21 can be flipped around the hinge connecting the movable support member 221 and the water tank 22 under the action of the drive mechanism 3 to open the avoidance air outlet 102.

[0052] In the above scheme, the air duct housing 1 includes a main body and an air outlet portion 13 fixedly arranged on the top wall of the main body. The air outlet portion 13 is formed on one side of the main body. The humidifying mechanism 2 is also installed on the top wall of the main body, and the humidifying mechanism 2 is arranged opposite to the air outlet portion 13. The air outlet 102 is opened on the side of the air outlet portion 13 facing the wet curtain assembly 21. The movable support member 221 is a rod-shaped structure. The upper end of the rod-shaped movable support member 221 is provided with a rotating support portion suitable for connecting to the rotating shaft 210. Preferably, the outer peripheral wall of one end of the rotating shaft 210 close to the movable support member 221 is concave inward along the circumferential direction to form an annular recess, and the rotating support portion is snapped into the annular recess. The annular recess can form a limit with the movable support member 221 in the axial direction to prevent the movable support member 221 from being separated from the wet curtain assembly 21 when the wet curtain assembly 21 switches between the blocking position and the avoidance position.

[0053] In one embodiment, see 2, Figure 7 and Figure 12 As shown, the rotating support portion is a U-shaped open slot formed at the upper end of the movable support member 221. One end of the rotating shaft 210 is rotatably placed in the open slot, and the open slot at the upper end of the rotating shaft 210 is snapped into the annular recess. The U-shaped open slot design facilitates the disassembly and assembly of the wet curtain assembly 21 and the movable support member 221, making it easier to clean the water tank 22 or the wet curtain assembly 21 separately later.

[0054] Of course, in other variant embodiments, the rotating support portion is a snap ring structure fixed to the upper end of the movable support member 221. One side of the snap ring structure is provided with an opening, and the rotating shaft 210 can be inserted into the snap ring structure through the opening. The rotating shaft 210 can rotate freely within the snap ring structure. The snap ring structure is made of an elastic material. Under normal circumstances, the size of the opening is smaller than the diameter of the rotating shaft 210 to prevent the rotating shaft 210 from escaping from the snap ring structure. When the wet curtain assembly 21 and the movable support member 221 are disassembled, the opening of the snap ring structure is squeezed by the rotating shaft 210 and can expand and deform, allowing the rotating shaft 210 to be inserted into or out of the snap ring structure. This embodiment does not limit the connection method between the movable support member 221 and the wet curtain assembly 21, as long as it can form a rotatable support for the wet curtain assembly 21 and the movable support member 221 will not be separated from the wet curtain assembly 21 when the wet curtain assembly 21 switches between the blocking position and the avoidance position.

[0055] In this embodiment, the movable support member 221 and the drive mechanism 3 are disposed on either side of the wet curtain assembly 21, one on the side of the wet curtain assembly 21 closer to the air outlet 102, and the other on the side of the wet curtain assembly 21 farther from the air outlet 102, thereby providing stable and reliable support for the wet curtain assembly 21 from both sides. For example, when the drive mechanism 3 is located on the side of the wet curtain assembly 21 farther from the air outlet 102, when a separate purification mode is activated, the telescopic member 32 can be controlled to retract to pull the wet curtain assembly 21 outward, causing the wet curtain assembly 21 to move away from the air outlet 102 until it reaches a predetermined avoidance position, thereby opening the air outlet 102. When the drive mechanism 3 is located on the side of the wet curtain assembly 21 closer to the air outlet 102, when a separate purification mode is activated, the telescopic member 32 can be controlled to extend to push the wet curtain assembly 21 outward, causing the wet curtain assembly 21 to move away from the air outlet 102 until it reaches a predetermined avoidance position, thereby opening the air outlet 102.

[0056] This embodiment is described in detail by taking the drive mechanism 3 being arranged on a side close to the air inlet 101 as an example, as follows:

[0057] The rotating shaft 210 of the wet curtain assembly 21 includes a fixed sleeve 2101 and a telescopic shaft 2102. The telescopic shaft 2102 is telescopically mounted within the fixed sleeve 2101. One end of the telescopic shaft 2102 slides within the fixed sleeve 2101, while the other end is rotatably connected to the telescopic member 32. The telescopic member 32 provides support for the wet curtain assembly 21 and can pull or push the wet curtain assembly 21 toward or away from the air outlet 102, thereby closing or opening the air outlet 102. The movable support 221 and telescopic member 32 are located on either side of the wet curtain assembly 21. The telescopic member 32 is located on the side of the wet curtain assembly 21 closest to the air outlet 102, while the movable support 221 is located on the side of the wet curtain assembly 21 away from the air outlet 102. The telescopic shaft 2102 is located on the side of the fixed sleeve 2101 closest to the air outlet 102. When the telescopic member 32 extends upward, it drives the telescopic shaft 2102 to extend, thereby pushing the wet curtain assembly 21, causing the wet curtain assembly 21 to flip away from the air outlet 102 with the hinge point between the movable support 221 and the water tank 22 as the rotation fulcrum, thereby opening the air outlet 102. When the telescopic member 32 retracts downward, it drives the telescopic shaft 2102 to retract, thereby pulling back the wet curtain assembly 21, causing the wet curtain assembly 21 to flip toward the air outlet 102, thereby restoring and closing the air outlet 102.

[0058] In the above scheme, the drive mechanism 3 is located at a set position below the rotating shaft 210, and the telescopic component 32 telescopes and moves in the vertical direction. In the humidification mode, the wet curtain assembly 21 is in the blocking position. At this time, the wet curtain assembly 21 can rotate in the vertical direction around its own rotating shaft 210 to achieve uniform immersion of the entire wet curtain 212 in water, thereby improving the humidification effect. In the purification mode, the wet curtain assembly 21 is driven by the drive mechanism 3 in the vertical direction and flips away from the air outlet 102 with the hinge point of the movable support 221 and the water tank 22 as the rotation fulcrum. The air outlet 102 and the wet curtain assembly 21 are opened at a set angle, and the air discharged from the air outlet 102 can be discharged directly into the external environment without passing through the wet curtain assembly 21. In actual use, the opening angle of the wet curtain assembly 21 can be reasonably set according to limiting factors such as the actual assembly space size to achieve a balance between limiting factors such as the air output and the assembly space size.

[0059] In some embodiments, the telescopic member 32 includes a telescopic plate 321 and a support plate 322. The telescopic plate 321 is in driving engagement with the output end of the drive member 31, allowing the telescopic plate 321 to rise or fall under the drive of the drive member 31. The lower end of the support plate 322 is connected to or in contact with the upper end of the telescopic plate 321, while the upper end of the support plate 322 is rotatably engaged with the rotating shaft 210. Specifically, the upper end of the support plate 322 is rotatably engaged with the telescopic rotating shaft 2102. The support plate 322 is adapted to rise and fall with the telescopic plate 321 as it rises or falls. The water tank 22 includes a water storage chamber with an open top. A support plate mounting portion 222 is provided near the air outlet 102 for mounting the support plate 322. The support plate mounting portion 222 includes a vertically extending guide groove extending vertically therethrough. The guide groove is independent of the water storage chamber to prevent water in the water storage chamber from entering the guide groove and damaging the drive mechanism 3. The support plate 322 is telescopically mounted within the guide slot, with the upper end of the support plate 322 extending and positioned above the guide slot. The support plate mounting portion 222 not only allows for mounting of the support plate 322 but also serves as a guide, ensuring that the support plate 322 can telescopically move vertically. The upper end of the support plate 322 is positioned above the guide slot, allowing the support plate 322 to fall back and remain positioned on the support plate mounting portion 222 when the telescopic plate 321 is retracted, preventing it from falling out of the support plate mounting portion 222.

[0060] In the above scheme, see Figure 2 、 Figure 7 and Figure 11As shown, the support plate mounting portion 222 can be a square tubular structure fixedly arranged on the water tank 22, and a guide groove is formed inside the square tubular support plate mounting portion 222. The cross-sectional shape and size of the guide groove match the cross-sectional shape and size of the support plate 322. It can be understood that the shape of the guide groove is the same as the shape of the support plate 322, and the size is slightly larger than the support plate 322.

[0061] In some embodiments, see Figure 2 、 Figure 6 、 Figure 7 and Figure 13 As shown, a pivot connection portion suitable for connecting to the rotating shaft 210 is fixedly provided at the upper end of the support plate 322, and a pivot hole is formed in the pivot connection portion. An opening is provided on one side of the pivot connection portion, and the rotating shaft 210 can be squeezed into the pivot hole through the opening. The pivot connection portion is an annular snap ring made of elastic material, and an opening is provided on the side or top thereof. Preferably, the opening is provided on the side of the annular snap ring to reduce the risk of the pivot connection portion being separated from the rotating shaft 210. The telescopic rotating shaft 2102 of the rotating shaft 210 can be squeezed into the annular snap ring through the opening. Through the design of the above-mentioned pivot connection portion, it is possible to realize the rotation support of the wet curtain assembly 21 and the reliable connection between the wet curtain assembly 21 and the telescopic component 32, while also facilitating disassembly and assembly.

[0062] In some embodiments, the outer peripheral wall of the end of the telescopic shaft 2102 is provided with an annular limiting groove, and the pivot connection portion is snapped into the limiting groove. The design of the limiting groove can limit the displacement of the pivot connection portion in the axial direction of the rotating shaft 210, preventing the pivot connection portion from being separated from the telescopic shaft 2102 or shifting when the wet curtain assembly 21 switches positions. In other preferred embodiments, the pivot connection portion can be hinged to the upper end of the support plate 322 to avoid mechanical obstruction.

[0063] In other alternative schemes, a waist-shaped connecting hole can be provided at one end of the rotating shaft 210 close to the air outlet 102, and a supporting rotating shaft is provided at the upper end of the support plate 322, which passes through the waist-shaped connecting hole. Through the cooperation of the supporting rotating shaft and the waist-shaped hole, both the rotation support of the wet curtain assembly 21 and the limiting connection between the telescopic component 32 and the wet curtain assembly 21 can be realized, which facilitates the switching of the wet curtain assembly 21 between the blocking position and the avoidance position.

[0064] In some embodiments, the air purification and humidification device further includes a housing having a drawer opening for withdrawing or inserting the water tank 22 and the wet curtain assembly 21. The water tank 22 and the wet curtain assembly 21 are designed to be retractable, facilitating subsequent cleaning and maintenance of the water tank 22 and the wet curtain assembly 21. When the water tank 22 and the wet curtain assembly 21 are designed to be retractable, the support plate 322 and the telescopic plate 321 utilize contact to achieve force transmission between them. Preferably, the support plate 322 and the telescopic plate 321 can be connected by magnetic attraction.

[0065] For example, the support plate 322 and the telescopic plate 321 are configured as mutually attracting magnetic members; alternatively, one of the support plate 322 and the telescopic plate 321 is configured as a metal member, and the other is configured as a magnetic member. When the water tank 22 and the wet curtain assembly 21 need to be cleaned, the magnetic attraction between the support plate 322 and the telescopic plate 321 is overcome, and the support plate 322, along with the wet curtain assembly 21 and the water tank 22, is withdrawn. After cleaning is complete, the support plate 322, along with the wet curtain assembly 21 and the water tank 22, is pushed into a preset installation position within the housing. In this preset installation position, the support plate 322 and the telescopic plate 321 face each other, and when the telescopic plate 321 is extended upward, it can contact the support plate 322. The two are attracted to each other by the magnetic attraction, achieving a secure connection between the support plate 322 and the telescopic plate 321. The telescopic plate 321 and the support plate 322 are connected by magnetic attraction, which makes it easier to separate the water tank 22 and the wet curtain assembly 21 from the driving mechanism 3 when pulling the water tank 22 and the wet curtain assembly 21 .

[0066] In some embodiments, see Figures 1 to 9 As shown, the wet curtain assembly 21 includes a water wheel disc 211 and a wet curtain 212. The water wheel disc 211 is rotatably mounted above the water tank 22. The water wheel disc 211 serves as a wet curtain bracket for mounting the wet curtain 212 and driving the wet curtain 212 to rotate. In humidification mode, the wet curtain assembly 21 is in a blocking position, blocking the air outlet 102. A rotating shaft 210 is fixedly disposed at the center of the water wheel disc 211. The wet curtain 212 is mounted on the water wheel disc 211. The bottoms of the water wheel disc 211 and the wet curtain 212 are immersed in the water in the water tank 22. The area of ​​the wet curtain 212 is larger than that of the air outlet 102, allowing the wet curtain 212 to completely block the air outlet 102 in humidification mode. The humidifying mechanism 2 also includes a rotation drive assembly for driving the wet curtain assembly 21 to rotate. The rotation drive assembly includes a power member and a first gear 213 arranged at the output end of the power member. The outer periphery of the water wheel turntable 211 is provided with meshing teeth suitable for engaging with the first gear 213. The power member is suitable for driving the water wheel turntable 211 to rotate by driving the first gear 213 to rotate, thereby driving the wet curtain 212 to rotate, so that the entire wet curtain 212 can absorb the moisture in the water tank 22.

[0067] In humidification mode, the power component of the rotary drive assembly drives the first gear 213 to rotate. The first gear 213 drives the water wheel disc 211 to rotate around the rotation axis 210 under the support of the movable support member 221 and the telescopic member 32, so that the wet curtain 212 continuously absorbs water from the water tank 22. In purification mode, the rotary drive assembly stops driving the first gear 213 to rotate, the water wheel disc 211 also stops rotating, and the drive mechanism 3 controls the wet curtain assembly 21 to switch to the avoidance position.

[0068] In some embodiments, see Figure 2 、 Figure 7 and Figure 11 As shown, the water tank 22 includes a main body and a wet curtain mounting portion 224 located on the side of the main body near the air outlet 102. The wet curtain mounting portion 224 is a protruding, extruded structure formed on the side of the main body near the air outlet 102. The wet curtain mounting portion 224 contains a cavity that matches the shape of the wet curtain assembly 21. When in the blocking position, the wet curtain assembly 21 stands upright within the wet curtain mounting portion 224. Specifically, the wet curtain mounting portion 224 includes two opposing curved walls and a vertical blocking wall connected to one side of the two curved walls. The vertical blocking wall is located near the air inlet 101. The width of the curved wall is no less than the width of the wet curtain assembly 21 to accommodate the wet curtain assembly 21, and the curvature of the curved wall matches the outer curvature of the wet curtain assembly 21. The provision of the wet curtain mounting portion 224 further improves the stability of the wet curtain assembly 21 within the water tank 22. The support plate mounting portion 222 is fixedly positioned in the middle of the vertical blocking wall.

[0069] Further, see Figure 2 、 Figure 7 and Figure 11 As shown, a hinge seat 223 is fixedly provided on the bottom wall of the water tank 22, and the hinge seat 223 includes two hinge plates arranged opposite to each other, and both hinge plates are provided with hinge holes. The lower end of the movable support member 221 is respectively provided with hinge shafts suitable for rotationally connecting with the hinge holes on the hinge seat 223.

[0070] In some embodiments, see Figures 1 to 4 、 Figures 6 to 9As shown, the humidifying mechanism 2 further includes a water tank 23, which is mounted above the water tank 22. The water tank 23 and the wet curtain assembly 21 are spaced apart from each other above the water tank 22. The water tank 23 is concavely arranged near the air outlet 102 to form a relief recess 231. The relief recess 231 is adapted to avoid and limit the wet curtain assembly 21 when the wet curtain assembly 21 is flipped to the relief position. The water tank 23 adopts a concave design on one side. When in the humidification mode, the concave relief recess 231 can play a role in guiding the air, guiding the humidified air to flow upward and be discharged. When in the purification mode, the relief recess 231 can serve as a storage and relief water wheel disc 211 to prevent the wet curtain assembly 21 from interfering with the water tank 23 when flipped outward. In this way, the opening angle of the wet curtain assembly 21 can be adaptively increased without increasing the total volume.

[0071] In one implementation of the above embodiment, a water outlet is provided at the bottom of the water tank 23 , and a water outlet valve is provided at the water outlet, and whether water is added to the water tank 22 can be controlled by controlling the opening and closing of the water outlet valve.

[0072] Optionally, the water tank 23 can be pulled out from the side of the casing together with the water tank 22 and the wet curtain assembly 21.

[0073] In some embodiments, see Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, the air duct housing 1 includes an air inlet 11, an air guide 12, and an air outlet 13, which are arranged in sequence from bottom to top, wherein the air inlet 11 and the air guide 12 serve as the main structure of the air duct housing 1, and the air outlet 13 is arranged above the main structure. An air inlet 101 is provided on the side wall of the air inlet 11, and a fan is arranged inside the air inlet 11. The air guide 12 is fixedly arranged above the air inlet 11, the air inlet end of the air guide 12 is connected to the air outlet end of the air inlet 11, and the air outlet end of the air guide 12 is connected to the air inlet end of the air outlet 13. A purification structure for purifying air is provided inside the air guide 12. The air outlet 13 and the water tank 22 are arranged above the air guide 12, and the two are arranged opposite to each other. The air outlet 102 is formed on the side of the air outlet 13 facing the water tank 22.

[0074] In the above solution, the air inlet 11, the air guide 12, and the air outlet 13 can be integrally formed. Alternatively, the air inlet 11, the air guide 12, and the air outlet 13 can be separate and connected and fixed in a detachable manner for easy processing and manufacturing.

[0075] Optionally, the first gear 213 for driving the wet curtain assembly 21 to rotate is set at the top position of the air outlet portion 13 of the air duct housing 1.

[0076] Alternatively, see Figure 2 and Figure 7As shown, the purification structure includes a filter element 121 and a deodorizing element 122, which are sequentially arranged in the air guide portion 12 along the flow direction of the wind. For example, the filter element 121 can be a filter net, and the deodorizing element 122 can be a deodorizing net. The filter element 121 and the deodorizing element 122 can be used to adsorb particulate matter or odor in the air, thereby achieving the purpose of purifying and refreshing the air. After the outside air is sucked into the air inlet portion 11, it passes through the filter element 121 and the deodorizing element 122 in sequence along the purification air duct, intercepting fine substances such as PM2.5, VOC, bacteria and viruses, and removing odors. After purification, the air continues to move upward and is directly discharged through the air outlet 102 of the air outlet portion 13, or is humidified by the wet curtain 212 and then discharged into the external environment.

[0077] In some embodiments, see Figure 2 、 Figure 7 and Figure 10 As shown, the driving component 31 is embedded in the air guide 12 to prevent the driving component 31 from interfering with the water trough 22 when the water trough 22 is pulled out. The top wall of the air guide 12 is relatively thick and is provided with a mounting groove for accommodating the driving component 31. The driving component 31 includes a fixed seat and a driving motor 311 fixed in the fixed seat. The output end of the driving motor 311 is provided with a second gear 312. The telescopic component 32 is provided with a tooth groove 3211 suitable for meshing with the second gear 312. The meshing transmission between the second gear 312 and the tooth groove 3211 drives the telescopic component 32 to rise or fall. There are multiple tooth grooves 3211, and the multiple tooth grooves 3211 are arranged at intervals along the vertical direction on the telescopic plate 321 so that the telescopic plate 321 forms a structure similar to a rack. After receiving the command, the driving mechanism 3 drives the second gear 312 to rotate forward or reverse, causing the telescopic plate 321 to rise or fall.

[0078] In the above solution, the driving mechanism 3 is fixedly arranged on the air guide portion 12 at a position close to the air outlet 102 , and the driving mechanism 3 corresponds to the support plate mounting portion 222 in upper and lower positions.

[0079] In this embodiment, the control mechanism of the wet curtain assembly 21 is as follows:

[0080] The regulation of the wet curtain assembly 21 is achieved through the cooperation of the driving component 31, the telescopic plate 321, the support plate 322, the rotating shaft 210, and the movable support 221. The driving component 31 is installed in the air guide part 12 of the air duct housing 1, the movable support 221 is installed in the water tank 22, the rotating shaft 210 is installed in the water wheel turntable 211, and the support plate 322 is installed in the water tank 22 in a telescopic and movably manner. When the purification mode is turned on, the telescopic plate 321 of the telescopic component 32 rises and lifts the support plate 322. The support plate 322 will drive the telescopic rotating shaft 2102 of the rotating shaft 210 to extend. At the same time, the water wheel turntable 211 will flip in the direction away from the air outlet 102 at the hinge point where the movable support 221 is connected to the water tank 22, so that the entire wet curtain assembly 21 is stored in the avoidance recess of the water tank 23. At this time, the space of the air outlet 102 becomes larger, which reduces the flow resistance of the air outlet 102, increases the air volume, reduces noise, improves the purification effect, and reduces the loss of wind to the wet curtain 212, thereby extending the service life of the wet curtain 212. When switched to the humidification mode, the telescopic plate 321 of the telescopic component 32 descends, and the support plate 322 descends accordingly, driving the telescopic shaft 2102 to shorten, and the water wheel turntable 211 flips toward the air outlet 102 at the hinge point where the movable support 221 is connected to the water tank 22, and rotates to a blocking position blocking the air outlet 102. The water wheel turntable 211 will rotate after cooperating with the first gear 213, so that the wet curtain 212 absorbs and replenishes moisture to complete humidification.

[0081] In this embodiment, the air purification and humidification device is an air purification humidifier or a freshener.

[0082] Example 2

[0083] like Figures 1 to 14 As shown, this embodiment provides an air purification and humidification method for an air purification and humidification device applied to any embodiment of the above-mentioned embodiment one. The air purification and humidification device has a purification mode and a humidification mode. The air flow direction of the purification mode is similar to that of the humidification mode. The difference is that after the air passes through the purification air duct, it will directly go to the outside through the air outlet 102 and no longer pass through the wet curtain 212.

[0084] The air purification and humidification method provided in this embodiment includes: receiving a signal, and controlling the action of the driving mechanism to switch between the humidification mode and the purification mode according to the received signal; wherein, when switching to the humidification mode, the driving mechanism 3 is actuated to switch the wet curtain assembly 21 from the avoidance position to the blocking position, and then the fan and the humidification mechanism 2 are controlled to start and enter the humidification mode; when switching to the purification mode, the driving mechanism 3 is actuated to switch the wet curtain assembly 21 from the blocking position to the avoidance position, and then the fan is controlled to start and enter the purification mode. In the above scheme, when a signal to start the humidification mode is received, it is first necessary to determine whether the wet curtain assembly 21 is in the blocking position: if so, the fan and the humidification mechanism 2 are directly controlled to start and enter the humidification mode; if not, the driving mechanism 3 is controlled to first switch the wet curtain assembly 21 to the blocking position, and then the fan and the humidification mechanism 2 are controlled to start.

[0085] Optionally, the receiving signal includes: receiving a humidity signal and controlling the switching between the humidification mode and the purification mode according to the received humidity signal; or receiving a user instruction and controlling the switching between the humidification mode and the purification mode according to the received user instruction.

[0086] Specifically, in one implementation of this embodiment, during the operation of the air purification and humidification device, the humidity information of the indoor air is detected in real time, and the air purification and humidification device is controlled to switch between the humidification mode and the purification mode based on the humidity information. The air purification and humidification device is provided with a humidity detection mechanism for detecting the indoor air. When the humidity detection mechanism detects that the indoor air is relatively dry and meets the preset humidification conditions, a signal to start the humidification mode is sent to the air purification and humidification device, and the air purification and humidification device enters the humidification mode. After it is determined that the indoor air meets the preset humidity requirement, the air purification and humidification device is controlled to shut down or switch to the purification mode.

[0087] In another implementation of this embodiment, during the operation of the air purification and humidification device, the air purification and humidification device is controlled to switch between the humidification mode and the purification mode according to a received user instruction.

[0088] In the above scheme, the air purification and humidification device can switch between the purification mode or the humidification mode according to the control instructions issued by the user, or the air purification and humidification device can also automatically switch between the purification mode and the humidification mode according to the environmental parameters and other information detected by the detection module. For example, the air purification and humidification device has an automatic gear. When the automatic gear is started, the air purification and humidification device can automatically switch between the purification mode and the humidification mode according to the humidity information of the air detected by the humidity detection mechanism. The air purification and humidification device also has a humidification gear and a purification gear, and the customer can choose freely. For example, the humidification mode or the purification mode can be started directly, or the purification mode can be started after the humidification mode has been running for a period of time, or the humidification mode can be started after the purification mode has been running for a period of time. In the automatic gear, the humidification or purification time is controlled according to the detection result of the humidity detection mechanism, and the running time of the humidification gear and the purification gear is determined by the customer.

[0089] In some embodiments of this embodiment, the air purification and humidification method further includes the following steps: receiving a shutdown signal, detecting the state of the telescopic component 32 of the drive mechanism 3, and if it is determined that the telescopic component 32 is in the extended state, controlling the telescopic plate 321 of the telescopic component 32 to retract into the drive mechanism 3 and then shutting down the device; if it is determined that the telescopic component 32 is in the retracted state, directly shutting down the device. This configuration ensures that the wet curtain assembly 21 is in the blocked position when not in use, and prevents the telescopic plate 321 of the telescopic component 32 from extending, causing interference between the telescopic plate 321 and the water tank 22 when the user draws or pulls the wet curtain assembly 21, the water tank 22, and the water tank 23, thereby causing mechanical damage to the structure.

[0090] See also Figure 14 In some implementations of this embodiment, the air purification and humidification device enters the humidification mode by default when it is turned on, and automatically switches between the purification mode and the humidification mode according to the user's instructions or according to the detection of the detection mechanism. The telescopic component 32 may experience the following four situations during operation:

[0091] ① Always run the humidification mode: After the machine is turned on, the humidification mode is kept running until the machine is turned off. In this case, the telescopic component 32 does not move, and the telescopic plate 321 remains inside the driving mechanism 3.

[0092] ② Always run the purification mode: After the power is turned on, the purification mode is selected and kept running until the power is turned off. In this case, the telescopic plate 321 rises when the purification mode is started and falls when the power is turned off.

[0093] ③ Run humidification first and then purification: After starting up, keep the humidification mode, and the telescopic component 32 does not move; after running for a period of time, turn on the purification mode, and the telescopic plate 321 rises; when shutting down, the telescopic plate 321 falls;

[0094] ④ Run purification first and then run humidification: After turning on the machine, select the purification mode and the telescopic plate 321 rises; after running for a period of time, turn on the humidification mode and the telescopic plate 321 falls; when shutting down the machine, the telescopic plate 321 does not move.

[0095] In the above four situations, when shutting down the device, the system will detect the position of the telescopic plate 321 of the telescopic component 32. If the telescopic plate 321 is extended, it will be retracted into the mechanism first; if it is already inside the mechanism, the device will be shut down directly. Therefore, the telescopic plate 321 will be inside the mechanism in the final state to ensure safety.

[0096] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
