[0056] The embodiments of the present application will be described in detail below with reference to the drawings, wherein the same or similar components are denoted by the same reference numerals throughout the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0057] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplification, the components and arrangements of the specific examples are described below. Of course, they are only examples and are not intended to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or arrangements discussed. In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the applicability of other processes and / or the use of other materials.

[0058] Next, with reference to the drawings, a fresh air component 100 according to the first embodiment of the present application is described.

[0059] Referring to Figure 1 and Figure 2The fresh air component 100 comprises a fresh air module 1 and a treatment module 2. The fresh air module 1 comprises a volute 11 and a centrifugal fan wheel 12 arranged in the volute 11. The upper portion of the volute 11 is formed as an air outlet section 111, which comprises a volute tongue portion 1112. The upper end of the air outlet section 111 is formed as a fan outlet 1111. The side edge of the fan outlet 1111 away from the volute tongue portion 1112 is a first edge 1111a. The side edge of the fan outlet 1111 opposite to the first edge 1111a is a second edge 1111b. The treatment module 2 is arranged on the top of the fresh air module 1. The treatment module 2 defines a treatment air duct 21a. The bottom of the treatment air duct 21a is provided with an air duct inlet 2111, which communicates the treatment air duct 21a with the fan outlet 1111. The air duct inlet 2111 comprises a main air outlet area 2111a and a bypass area 2111b arranged along the direction from the first edge 1111a to the second edge 1111b. The fan outlet 1111 is located directly below the main air outlet area 2111a and obliquely below the bypass area 2111b. The bottom of the treatment air duct 21a is provided with a downwardly protruding air guide wall 213, which extends from the side edge of the bypass area 2111b away from the main air outlet area 2111a and downwardly towards the fan outlet 1111.

[0060] The applicant has found in the research that when a centrifugal fan is used as a power source to drive air flow, if the size of the air duct inlet connected with the fan outlet is larger than the size of the fan outlet, the part exceeding the size of the fan outlet is prone to generate vortex. The vortex not only causes air power loss and reduces the overall efficiency of the fresh air system, but also causes a large noise in the air duct. If the size of the air duct inlet is designed to be consistent with the size of the fan outlet, although the noise problem caused by the vortex can be avoided, the ventilation efficiency is low.

[0061] To solve the above technical problems, in the technical scheme of the present application, the bottom of the treatment air duct 21a is provided with a downwardly protruding air guide wall 213, which extends from the side edge of the bypass area 2111b away from the main air outlet area 2111a and downwardly towards the fan outlet 1111. When the air flows through the bypass area 2111b, it is guided by the air guide wall 213 and directly enters the bypass area 2111b, without being subjected to shear force and centrifugal force due to the sudden expansion of the air duct inlet 2111, so as to form vortex. The reduction of the vortex not only reduces the air power loss, but also significantly reduces the noise, and improves the overall performance of the system and the user experience.

[0062] In addition, the arrangement of the bypass opening area 2111b increases the area of the air duct inlet 2111, improves the ventilation efficiency, and to some extent, increases the contact area of the air and the processing module 2, thereby improving the processing capacity of the processing module 2 and the user experience. Therefore, the technical scheme of the present application can reduce the working noise while ensuring a relatively high ventilation efficiency.

[0063] In the embodiments of the present application, the fact that the fan outlet 1111 is located directly below the main air outlet area 2111a means that the upward orthogonal projection of the fan outlet 1111 falls completely within the main air outlet area 2111a.

[0064] In the embodiments of the present application, the function of the processing module 2 is not limited, for example, it can include at least one of dust removal function, humidification function, dehumidification module, preheating function, precooling function, etc.

[0065] In the embodiments of the present application, the shape of the air guide wall 213 is not limited. The air guide wall 213 can be linear, extending directly to the vicinity of the fan outlet 1111 for directly guiding the airflow of the bypass opening area 2111b. The air guide wall 213 can be curved or arc-shaped to guide the airflow in a more gentle manner, thereby reducing airflow turbulence and noise. In addition, when the air guide wall 213 is linear, it can be connected by multiple straight lines to segment the air guide wall, thereby reducing the possibility of generating vortex flow.

[0066] In some embodiments, referring to Figure 1 and Figure 2 , the top end of the volute 11 is provided with a top plate 112, the top plate 112 includes an extension 1121 extending from the second edge 1111b towards a direction away from the first edge 1111a (for example, as shown in Figure 1 , the extension 1121 extends from left to right), and the air guide wall 213 is located on the side of the extension 1121 away from the fan outlet 1111.

[0067] In the above technical scheme, by providing the top plate 112 at the top end of the volute 11, the area of the airflow after flowing out of the fan outlet 1111 is increased, which helps to reduce the resistance of the airflow at the outlet, so that the airflow can flow out more smoothly, thereby improving the airflow efficiency and performance of the fan. The extension 1121 of the top plate 112 extends from left to right, and the air guide wall 213 is located on the side of the extension 1121 away from the fan outlet 1111, so that the air guide wall 213 can guide the airflow to a farther bypass opening area 2111b, further increasing the area of the airflow after flowing out of the fan outlet 1111, and improving the air supply capacity of the fan.

[0068] In addition, the presence of the top plate 112 enhances the structural strength of the top of the volute 11, so that the fan can better resist deformation caused by airflow impact and vibration during operation.

[0069] In some embodiments, referring to Figure 3 The processing module 2 comprises a partition rib 2114 spaced between the main air outlet area 2111a and the bypass air outlet area 2111b, the main air outlet area 2111a is provided with a protective screen 212, and the bypass air outlet area 2111b is open, and the air guide wall 213 is located on the side away from the fan outlet 1111 below the partition rib 2114 as a whole.

[0070] In the above technical solution, the partition rib 2114 effectively separates the main air outlet area 2111a and the bypass air outlet area 2111b, the main air outlet area 2111a is provided with a protective screen 212, and the partition rib 2114 serves as the edge of the main air outlet area 2111a and can support the protective screen 212. It is worth mentioning that the protective screen 212 can be assembled as a separate component in the main air outlet area 2111a or can be integrally formed with the main air outlet area 2111a.

[0071] Since the fan outlet 1111 is located directly below the main air outlet area 2111a, the main air outlet area 2111a is provided with a protective screen 212, which is beneficial to prevent the operator from mistakenly touching the fresh air impeller 12, the motor, etc. when installing or maintaining by reaching into the fan outlet 1111 through the main air outlet area 2111a; in addition, the protective screen 212 provided in the main air outlet area 2111a increases the resistance of the airflow passing through the main air outlet area 2111a, and in combination with the open setting of the bypass air outlet area 2111b, more airflow can be guided to the bypass air outlet area 2111b to increase the uniformity of airflow distribution, so that the airflow flow rate through the processing module 2 is more uniform, which is beneficial to the implementation of the processing process of the processing module 2.

[0072] The air guide wall 213 is located on the side away from the fan outlet 1111 below the partition rib 2114 as a whole, that is, the projection of the air guide wall 213 in the up-down direction does not intrude into the main air outlet area 2111a, thereby ensuring that the bypass air outlet area 2111b does not interfere with or compete with the downstream airflow below the main air outlet area 2111a to increase the disturbance of the airflow, and the air guide wall 213 can more effectively guide the airflow below the bypass air outlet area 2111b, so that the airflow below the bypass air outlet area 2111b flows downstream and upwards, thereby reducing the occurrence of vortex phenomenon and improving the overall performance of the fan.

[0073] Exemplarily, referring to Figure 1 and Figure 4, the air guide wall 213 extends from the upper right to the lower left, the air guide wall 213 is located on the side away from the fan outlet 1111 below the partition rib 2114 as a whole, the projection in the up-down direction is located on the right side below the main air outlet area 2111a as a whole, without invading the main air outlet area 2111a, so as to ensure that the bypass air outlet area 2111b does not interfere with or compete with the main air outlet area 2111a below the main air outlet area 2111a to increase the disturbance of the airflow.

[0074] In some embodiments, referring to Figure 4 , the air guide wall 213 includes an inclined segment 2131 extending from the bypass air outlet area 2111b to the direction close to the fan outlet 1111 from top to bottom and inclined to the vertical direction.

[0075] In the above technical solution, the arrangement of the inclined segment 2131 of the air guide wall 213 enables the airflow below the bypass air outlet area 2111b to be more smoothly guided to the bypass air outlet area 2111b, reducing the turbulence and vortex of the airflow below the bypass air outlet area 2111b, and improving the flow efficiency and stability of the airflow. In addition, reducing the turbulence and vortex of the airflow can reduce the noise generated by the airflow impacting the air duct wall, improving the quiet performance of the equipment.

[0076] The arrangement of the inclined segment 2131 of the air guide wall 213 optimizes the airflow path, reduces the resistance and friction of the airflow in the air duct, thereby reducing the energy consumption of the fan and improving the energy efficiency of the entire system. Moreover, the structure of the air guide wall 213 can also be simplified, which is beneficial to the processing and molding of the air guide wall 213.

[0077] In the embodiments of the present application, the inclined segment 2131 of the air guide wall 213 extends in the direction of the fan outlet 1111, and the inclination angle thereof is not limited, for example, the inclination angle of the inclined segment 2131 of the air guide wall 213 is close to the inclination angle of the outlet slope of the fan outlet 1111.

[0078] In some embodiments, referring to Figure 4 , the air guide wall 213 further includes a vertical segment 2132 extending vertically downward from the lower end of the inclined segment 2131, and the vertical height H1 of the vertical segment 2132 is less than the vertical height H2 of the inclined segment 2131.

[0079] In the above technical solution, the inclined segment 2131 has effectively guided the airflow to the direction of the fan outlet 1111, and the addition of the vertical segment 2132 further ensures that the airflow can maintain a stable flow direction when flowing out of the fan outlet 1111, reduces the turbulence of the airflow, and improves the accuracy and efficiency of airflow guidance.

[0080] In addition, the vertical section 2132 as a part of the air guide wall 213 not only plays a role of air flow guiding, but also enhances the structural stability of the entire air guide wall 213, and improves the overall strength and durability of the air duct system.

[0081] In some embodiments, in combination with Figure 3 , Figure 4 and Figure 5 , the processing air duct 21a comprises an integrally formed air duct frame 21, the air duct frame 21 defines the processing air duct 21a, and the air duct frame 21 comprises a bottom plate 211, a protective screen 212, and an air guide wall 213, the bottom plate 211 is formed with an air duct inlet 2111, the bottom plate 211 comprises a partition rib 2114 spaced between a main air port area 2111a and a bypass port area 2111b, and the protective screen 212 is arranged at the main air port area 2111a.

[0082] In the above technical solution, the air duct frame 21 adopts an integrally formed design, which reduces the number of components, reduces the assembly gap between components, improves the overall structural strength and sealing performance, and is beneficial to prevent air leakage and improve the efficiency of the air duct system. Since the air guide wall 213 does not need to be separately provided, the number of components is further reduced, and the overall structural strength and sealing performance are improved.

[0083] In the embodiments of the present application, the integrated air duct frame 21 refers to that the air duct frame 21 is an integral structural member and cannot be disassembled. For example, the air duct frame 21 can be an integrally formed member, that is, it is made of an integral material and has no detachable parts, or for another example, the air duct frame 21 can comprise a bottom plate 211, a protective screen 212, and an air guide wall 213, and the multiple parts can be processed respectively in the manufacturing process, but are tightly combined together through a fixed connection process (such as bonding, welding, etc.) to form an indivisible whole.

[0084] In some embodiments, in combination with Figure 3 , Figure 4 and Figure 5 , the bottom plate 211 comprises an edge rib 2112 arranged at the bypass port area 2111b away from the main air port area 2111a, the air guide wall 213 extends downward from the edge rib 2112, and a part of the air guide wall 213 is recessed toward the direction of the main air port area 2111a to form a reinforcing rib 2113 connected between the partition rib 2114 and the edge rib 2112, and the reinforcing rib 2113 divides the bypass port area 2111b into two sub-air ports 2111b1 located on both sides of the reinforcing rib 2113.

[0085] In the above technical solution, the edge rib 2112 is arranged on the side of the bypass opening area 2111b away from the main air opening area 2111a, and the reinforcing rib 2113 is connected between the partition rib 2114 and the edge rib 2112, thereby enhancing the structural strength of the air duct frame 21 in this area and improving the overall stability and durability. The air guide wall 213 extends downward from the edge rib 2112, which can effectively guide the airflow direction, reduce vortex and turbulence, and improve the stability and uniformity of the airflow.

[0086] In addition, part of the air guide wall 213 is recessed towards the direction of the main air opening area 2111a to form the reinforcing rib 2113 connected between the partition rib 2114 and the edge rib 2112. Compared with arranging the reinforcing rib 2113 separately, it is easier to shape and demold during production, improving production efficiency while increasing structural strength.

[0087] In some embodiments, in combination with Figure 4 , Figure 5 and Figure 6 , the left and right sides of the lower end of the treatment module 2 respectively have downwardly extending side flaps 23, the length direction of the side flaps 23 extends in the front-rear direction, and the two side flaps 23 are respectively clamped on both sides of the upper end of the fresh air module 1 to enable the treatment module 2 to be installed by being pushed from front to back relative to the fresh air module 1.

[0088] In the above technical solution, by arranging downwardly extending side flaps 23 on the left and right sides of the lower end of the treatment module 2 and clamping them on both sides of the upper end of the fresh air module 1, the side flaps 23 not only have the function of stabilizing the installation, but also have the function of guiding. During installation, the side flaps 23 can guide the treatment module 2 to be correctly inserted into the upper end of the fresh air module 1, avoiding misalignment or damage during installation, achieving stable installation of the treatment module 2 relative to the fresh air module 1, and ensuring that the air duct inlet 2111 and the fan outlet 1111 of the treatment module 2 and the fresh air module 1 are aligned during installation, thereby ensuring smooth airflow.

[0089] In addition, the design of the side flaps 23 enables the treatment module 2 to be installed by being pushed from front to back relative to the fresh air module 1. This installation method can effectively prevent the treatment module 2 from shaking or falling in the front-rear direction, improving the stability and reliability of the entire system. At the same time, this installation method also simplifies the installation steps, improves the installation efficiency, and is convenient for subsequent maintenance and disassembly work, reducing maintenance costs.

[0090] This installation method enables the treatment module 2 and the fresh air module 1 to have a certain adaptability. Even if there is a slight difference in the size of the fresh air module 1 or the treatment module 2, stable installation can be achieved by adjusting the clamping force of the side flaps 23, improving the compatibility and flexibility of the system.

[0091] In some embodiments, referring to Figure 4 , the two side overturning edges 23 respectively extend in a direction away from each other from top to bottom to flare open downward. For example, the left side overturning edge 23 extends leftward from top to bottom, and the right side overturning edge 23 extends rightward from top to bottom.

[0092] In the above technical solution, the two side overturning edges 23 extend in a direction away from each other from top to bottom to form a flared open structure downward, so that the processing module 2 is easier to butt joint with the upper end of the fresh air module 1 during installation. Specifically, the inclined side overturning edge 23 can serve as a guide structure to help the operator more accurately position the installation of the module. Since the two side overturning edges 23 respectively extend in a direction away from each other from top to bottom to flare open downward, during installation, the operator does not need to carefully butt joint, and even if there is a deviation in butt joint, stable butt joint can be achieved due to the remaining fitting allowance. From the perspective of production, the processing module 2 has certain adaptability to the size and shape of the fresh air module 1. Even if there is a certain size difference or shape change at the upper end of the fresh air module 1, the inclined side overturning edge 23 can still achieve stable installation, improving the compatibility and flexibility of the system.

[0093] In the embodiments of the present application, the specific angle of the inclined extension of the side overturning edge 23 should be determined according to actual needs and system design. For example, excessive flaring open may reduce the contact area between the side overturning edge 23 and the fresh air module 1, thereby affecting the structural stability; and too small flaring open may not be able to fully play its role in guiding installation.

[0094] In some embodiments, in combination with Figure 4 , Figure 5 and Figure 6 , the front side of the lower end of the processing module 2 has a front overturning edge 24 extending downward, the length direction of the front overturning edge 24 extends along the left-right direction, and the left and right ends are respectively connected with the front ends of the left and right side overturning edges 23, and the front overturning edge 24 blocks the front side of the upper end of the fresh air module 1.

[0095] In the above technical solution, the front overturning edge 24 extends along the left-right direction and is connected with the front ends of the left and right side overturning edges 23, forming a relatively complete side-front surrounding structure, so that the processing module 2 is more firmly fixed at the upper end of the fresh air module 1, not only improving the overall stability of the system, but also helping to prevent the processing module 2 from being displaced or falling off due to external force during use.

[0096] In addition, the provision of the front flange 24 provides a more explicit positioning reference for the installation of the treatment module 2. During the installation process, the user can judge whether the installation position of the treatment module 2 is correct by observing whether the front flange 24 abuts and blocks the front side of the upper end of the fresh air module 1. This helps to improve the installation accuracy and ensure the alignment of the interface between the treatment module 2 and the fresh air module 1, thereby reducing the problem of airflow obstruction or leakage caused by improper installation.

[0097] In some embodiments, in combination with Figure 6 and Figure 7 , the front flange 24 has a connecting hole 241 extending in the front-rear direction, and the front flange 24 is fixedly connected to the front end of the fresh air module 1 through the connecting hole 241 by a fastener.

[0098] In the above technical solution, the front flange 24 is fixedly connected to the front end of the fresh air module 1 by a fastener extending in the front-rear direction, which can significantly enhance the structural stability between the treatment module 2 and the fresh air module 1. In addition, through the locking action of the fastener, the shaking or displacement of the treatment module 2 in the front-rear direction is also limited, thereby improving the reliability and durability of the entire system. Moreover, such connection makes the front flange 24 easily form a close fit with the front side of the upper end of the fresh air module 1, thereby forming an effective airflow barrier. This helps to prevent airflow from leaking at the interface between the treatment module 2 and the fresh air module 1, improving the sealing performance and energy efficiency of the system.

[0099] In the embodiments of the present application, the type of fastener is not limited, which can be a bolt, a screw, a rivet, etc. At the same time, the specifications (such as length, diameter, etc.) of the fastener should also be matched with the size of the connecting component to ensure the stability and reliability of the connection.

[0100] In addition, the installation position and number of fasteners should be determined according to the size, shape and connection requirements of the fresh air module 1 and the front flange 24. Generally, the fasteners should be installed at the stress points or key positions of the connecting components to ensure the strength and stability of the connection. At the same time, the number of fasteners should also be moderate to ensure the stability of the connection while avoiding excessive increase in connection cost and weight.

[0101] Exemplarily, as shown in Figure 7 , the fastener is a screw, the front side of the lower end of the treatment module 2 has a front flange 24 extending downward, the length direction of the front flange 24 extends in the left-right direction, the front flange 24 is provided with a boss protruding forward at positions close to the left and right ends, the boss defines a recess open rearward, the left and right side surfaces of the boss are respectively provided with a plurality of reinforcing rib plates, the center of the boss is provided with a connecting hole 241, the front part of the upper end of the fresh air module 1 is provided with a threaded seat at a position corresponding to the recess, the center of the threaded seat is provided with a threaded hole, and the screw as the fastener passes through the connecting hole 241 from front to back and is threadedly connected with the threaded hole on the threaded seat.

[0102] In some embodiments, in combination Figure 8 and Figure 9 The lower end of the treatment module 2 has a first insertion part 22, and the upper end of the fresh air module 1 has a second insertion part 13. The first insertion part 22 is inserted into the second insertion part 13 in the horizontal direction to limit the upward movement of the treatment module 2 relative to the fresh air module 1.

[0103] In the above technical solution, by designing the first insertion part 22 and the second insertion part 13, the first insertion part 22 is inserted into the second insertion part 13 in the horizontal direction, which can simplify the installation process of the treatment module 2 and the fresh air module 1. Specifically, this insertion method does not require complex fixing devices or tools, and only needs to align and gently push them in, which greatly improves the installation efficiency.

[0104] In addition, the insertion structure not only facilitates installation, but also effectively limits the upward movement of the treatment module 2 relative to the fresh air module 1, thereby enhancing the structural stability of the entire fresh air component 100. This stability is crucial to prevent module loosening caused by airflow fluctuations or fan vibration, and helps to prolong the service life of the equipment.

[0105] In the embodiments of the present application, the shape and size of the insertion part are not limited. For example, the shape of the insertion part can be rectangular, circular, trapezoidal, etc. It can be understood that the shape and size of the first insertion part 22 and the second insertion part 13 are matched to achieve smooth insertion and stable connection.

[0106] In some embodiments, the treatment module 2 is installed by pushing from front to back relative to the fresh air module 1, the first insertion part 22 is located at the rear of the lower end of the treatment module 2, and the second insertion part 13 is located at the rear of the upper end of the fresh air module 1. The first insertion part 22 is inserted into the second insertion part 13 in the front-rear direction.

[0107] In the above technical solution, the treatment module 2 is installed by pushing from front to back relative to the fresh air module 1, which simplifies the installation steps and improves the installation efficiency. This installation method allows the operator to more intuitively judge the insertion position during the installation process, reducing the possibility of misoperation. In combination with the side turning edge 23 in the above embodiment, the length direction of the side turning edge 23 extends in the front-rear direction, and the two side turning edges 23 are clamped on both sides of the upper end of the fresh air module 1, providing a guiding effect for the treatment module 2 to be installed by pushing from front to back relative to the fresh air module 1, so that the treatment module 2 is installed by pushing from front to back relative to the fresh air module 1.

[0108] The first plug-in part 22 is located at the lower end of the processing module 2, and the second plug-in part 13 is located at the upper end of the fresh air module 1. This design makes the connection after plugging more stable. Since the plug-in part is located at the rear, combined with the front turning edge 24 in the above-mentioned embodiment shielding the upper end of the fresh air module 1, the connection between the processing module 2 and the fresh air module 1 is more stable, which can more effectively resist the force in the front-rear direction, and helps to prevent the processing module 2 from being displaced or falling off due to external force during use, thereby improving the structural stability of the entire system.

[0109] In some embodiments, in combination with Figure 8 and Figure 9 , the first plug-in part 22 is formed as a plug-in pin extending backward, and the second plug-in part 13 is formed with a plug-in hole penetrating in the front-rear direction or a plug-in slot recessed backward. Thus, during installation, the two side turning edges 23 are clamped on both sides of the upper end of the fresh air module 1, and only the plug-in pin needs to be aligned with the plug-in hole or the plug-in slot, and pushed in the front-rear direction until the front turning edge 24 of the processing module 2 abuts against the front end of the fresh air module 1 to complete the plugging, which simplifies the installation steps and improves the installation efficiency. Moreover, the first plug-in part 22 of this design can occupy the space outside the processing module 2, so that the structure of the processing module 2 can be designed flexibly.

[0110] In some embodiments, in combination with Figure 9 and Figure 10 , the processing module 2 is configured as a purification module 2a, which includes an air duct frame 21 defining a processing air duct 21a, and a purification unit 2a1 which is pullably coupled with the air duct frame 21 and is detachably arranged in the processing air duct 21a.

[0111] In the above technical solution, the pullable coupling design between the purification unit 2a1 and the air duct frame 21 allows the operator to easily pull out the purification unit 2a1 from the processing air duct 21a for cleaning or replacing the purification unit 2a1, etc. This simplifies the maintenance process, reduces maintenance costs, and also helps to improve the operating efficiency and purification effect of the equipment.

[0112] In addition, the pullable coupling purification unit 2a1 allows users to replace different models or functional purification units 2a1 according to actual needs, thereby achieving effective purification of different pollutants. This design improves the flexibility and adaptability of the equipment, meeting the needs of different users and use scenarios.

[0113] In some embodiments, referring to Figure 10, the purification unit 2a1 is two and includes the charge net unit 2a11 and the dust collection net unit 2a12 arranged in sequence from bottom to top. Thus, the purification of particulate matters in the air can be realized. The charge net unit 2a11 can charge the fine particulate matters in the air, and the dust collection net unit 2a12 can effectively collect the charged particulate matters by using the electrostatic adsorption principle, thereby improving the purification efficiency. In addition, the independent charge net unit 2a11 and the dust collection net unit 2a12 are designed so that the user can clean or replace them respectively without replacing the entire purification unit 2a1 together. This reduces the maintenance cost and prolongs the service life of the overall equipment.

[0114] In some embodiments, referring to Figure 11 , the upper side of the treatment module 2 is further provided with a humidification module 3, and the humidification module 3 defines a humidification air duct 31 in communication with the treatment air duct 21a.

[0115] In the above technical solution, by arranging the humidification module 3 above the treatment module 2 and defining the humidification air duct 31 in communication with the treatment air duct 21a, the humidification treatment of the air can be realized. In a dry environment, the humidification treatment can significantly improve the comfort of indoor air and reduce skin discomfort caused by dry air.

[0116] In addition, the communication between the humidification air duct 31 and the treatment air duct 21a enables the air after the purification treatment to directly enter the humidification module 3 for humidification treatment without additional air flow ducts. This reduces air flow resistance, improves air flow efficiency, and ensures the simultaneous realization of purification and humidification effects. Of course, the air flow introduced by the fresh air module 1 can first flow through the purification module 2a and then flow through the humidification module 3, and at least one of the humidification and purification can be realized according to the type selection and opening control of the purification module 2a and the humidification module 3.
