[0051] Specifically, the housing component 1 is formed with an air handling duct 11, an indoor airflow inlet 12, an indoor airflow outlet 13 and a fresh air inlet 14. The air handling duct 11 includes a wind wheel chamber 111 and an air outlet duct 112. The indoor airflow inlet 12 and the fresh air inlet 14 are both located at the air inlet side of the wind wheel chamber 111. The indoor airflow inlet 12 and the fresh air inlet 14 are both suitable for communicating with the wind wheel chamber 111. The air outlet duct 112 is located at the air outlet side of the wind wheel chamber 111, which facilitates the airflow in the air handling duct 11. The air outlet duct 112 and the wind wheel chamber 111 can be selectively connected or disconnected. The indoor airflow outlet 13 is suitable for connecting the air outlet duct 112 with the room. A fresh air valve 141 for opening and closing the fresh air inlet 14 is provided at the fresh air inlet 14.

[0052] Optionally, the air outlet duct 112 is disposed above the wind wheel cavity 111, and the indoor air flow outlet 13 is disposed above the indoor air flow inlet and the fresh air inlet 14. In this way, air flow turbulence in the air treatment device 100 can be avoided.

[0053] The first fan component 2 includes a first wind wheel 21 disposed in the wind wheel chamber 111, and the first fan component 2 also includes a first motor 22, which is connected to the first wind wheel 21 to drive the first wind wheel 21 to rotate. The fresh air duct 3 is connected to the fresh air inlet 14 and extends outward, the fresh air duct 3 is connected to the outside of the fresh air inlet 14, and the fresh air duct 3 is connected to the outside of the fresh air inlet 14. The exhaust component 4 is formed with an exhaust air duct 41, one end of the exhaust component 4 is connected to the fresh air duct 3, one end of the exhaust component 4 is located outside the fresh air inlet 14, the other end of the exhaust component 4 is connected to the shell component 1 and the other end of the exhaust component 4 is located at the wind outlet side of the wind wheel chamber 111, the exhaust air duct 41 is connected to the fresh air duct 3, and the exhaust air duct 41 and the wind wheel chamber 111 can be selectively connected or isolated.

[0054] In the description of the present invention, "first feature" or "second feature" may include one or more of the features.

[0055] Among them, the air treatment device 100 has a fresh air mode and an exhaust mode. In the fresh air mode, the air outlet duct 112 is connected to the wind wheel cavity 111, the exhaust duct 41 is separated from the wind wheel cavity 111, and the fresh air valve 141 opens the fresh air inlet 14; in the exhaust mode, the air outlet duct 112 is separated from the wind wheel cavity 111, the exhaust duct 41 is connected to the wind wheel cavity 111, and the fresh air valve 141 closes the fresh air inlet 14.

[0056] For example, Figure 5 As shown, the air treatment device 100 is in the fresh air mode, and the fresh air valve 141 is in an open state to open the fresh air inlet 14. The fresh air flows through the fresh air pipe 3 and enters the air treatment duct 11 from the fresh air inlet 14, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the air outlet duct 112 is connected with the wind wheel cavity 111, and the exhaust duct 41 is separated from the wind wheel cavity 111. Therefore, the fresh air flow then enters the air outlet duct 112 from the wind wheel cavity 111, and finally enters the room from the indoor air flow outlet 13, so that the outdoor fresh air can be introduced into the room.

[0057] For example, Figure 6As shown, when the air treatment device 100 is in the exhaust mode, the fresh air valve 141 is in a closed state to close the fresh air inlet 14, and the indoor air enters the air treatment duct 11 through the indoor air flow inlet 12, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the air outlet duct 112 is separated from the wind wheel cavity 111, and the exhaust duct 41 is connected to the wind wheel cavity 111. Therefore, the indoor airflow then enters the exhaust duct 41 from the wind wheel cavity 111, and is finally discharged to the outside through the exhaust duct 41 through the fresh air pipe 3, so that the indoor dirty air can be discharged to the outside.

[0058] According to the air treatment device 100 of the embodiment of the present invention, an air treatment duct 11, a fresh air inlet 14, and an exhaust component 4 with an exhaust channel are arranged in the shell component 1. The air treatment duct 11 includes an air outlet duct 112 and a wind wheel cavity 111 in which a first wind wheel 21 is arranged, and one end of the exhaust component 4 is connected and communicated with the fresh air duct 3. A fresh air valve 141 is arranged at the fresh air inlet 14. The air outlet duct 112 and the exhaust duct 41 are selectively communicated with and disconnected from the wind wheel cavity 111, which can meet the requirements of switching between different working modes such as the fresh air mode and the exhaust mode of the air treatment device 100, and can introduce outdoor fresh air into the room and directly discharge indoor dirty air to the outside, so that the indoor air quality is maintained good; this also optimizes the arrangement design method between different air ducts, so that the internal structure of the air treatment device 100 is simpler.

[0059] According to some embodiments of the present invention, the air treatment device 100 also has an internal circulation mode, and an indoor circulation valve 19 for opening and closing the indoor air flow inlet 12 is provided at the indoor air flow inlet 12; wherein, in the fresh air mode, the indoor circulation valve 19 closes or opens the indoor air flow inlet 12; in the exhaust mode, the indoor circulation valve 19 opens the indoor air flow inlet 12; in the internal circulation mode, the indoor circulation valve 19 opens the indoor air flow inlet 12, the fresh air valve 141 closes the fresh air inlet 14, the air outlet duct 112 is connected to the wind wheel cavity 111, and the exhaust duct 41 is separated from the wind wheel cavity 111.

[0060] In this way, the requirement of switching between different working modes such as fresh air mode, internal circulation mode and exhaust mode of the air treatment device 100 can be met, so as to introduce outdoor fresh air into the room, or introduce indoor polluted air into the room, or process the indoor air through the internal circulation mode, for example, the indoor air can be purified and humidified through the internal circulation mode to improve the indoor air quality and keep the indoor air quality in a good state. At the same time, the arrangement design between different air ducts such as the air treatment duct 11, the exhaust duct 41 and the fresh air duct 3 of the air treatment device 100 is optimized, so that the internal structure of the air treatment device 100 is simpler.

[0061] Optionally, a purification component 9 can be provided in the air treatment duct 11 for purifying the air. The purification component 9 can be provided on the air inlet side of the wind wheel cavity 111 , and the airflow entering the air treatment duct 11 from the fresh air inlet 14 or the indoor air flow inlet 12 can be purified by the purification component 9 .

[0062] Optionally, a humidifying component 7 may be provided in the air outlet duct 112, and the humidifying component 7 is used to humidify the airflow.

[0063] For example, Figure 5 As shown, the air treatment device 100 is in the fresh air mode, the fresh air valve 141 is in the open state to open the fresh air inlet 14, and the indoor circulation valve 19 is in the closed state to close the indoor air flow inlet 12. The fresh air flows through the fresh air pipe 3 and enters the air treatment duct 11 from the fresh air inlet 14, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the air outlet duct 112 is connected with the wind wheel cavity 111, and the exhaust duct 41 is separated from the wind wheel cavity 111. Therefore, the fresh air flow then enters the air outlet duct 112 from the wind wheel cavity 111, and finally enters the room from the indoor air flow outlet 13, so that the outdoor fresh air can be introduced into the room.

[0064] For example, when the air treatment device 100 is in the fresh air mode, the fresh air valve 141 is in the open state of opening the fresh air inlet 14, the indoor circulation valve 19 is in the open state of opening the indoor air flow inlet 12, the fresh air flows through the fresh air pipe 3 and enters the air treatment duct 11 from the fresh air inlet 14, the indoor air flows through the indoor air flow inlet 12 and enters the air treatment duct 11, and the fresh air flow and the indoor air flow both flow through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the air outlet duct 112 is connected to the wind wheel cavity 111, the exhaust air duct 41 is separated from the wind wheel cavity 111, the fresh air flow and the indoor air flow both enter the air outlet duct 112 from the wind wheel cavity 111, and finally enter the room from the indoor air flow outlet 13, so that the outdoor fresh air and the treated indoor air flow can be introduced into the room.

[0065] For example, Figure 6 As shown, in the exhaust mode, the air treatment device 100 has the fresh air valve 141 in a closed state to close the fresh air inlet 14, and the indoor circulation valve 19 in an open state to open the indoor air flow inlet 12. The indoor airflow enters the air treatment duct 11 through the indoor air flow inlet 12, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the air outlet duct 112 is separated from the wind wheel cavity 111, and the exhaust duct 41 is connected to the wind wheel cavity 111. Therefore, the indoor airflow then enters the exhaust duct 41 from the wind wheel cavity 111, and finally is discharged from the exhaust duct 41 to the outside through the fresh air pipe 3, so that the indoor dirty air can be discharged to the outside.

[0066] For example, when the air treatment device 100 is in the internal circulation mode, the fresh air valve 141 is in a closed state to close the fresh air inlet 14, and the indoor circulation valve 19 is in an open state to open the indoor air flow inlet 12. The indoor airflow enters the air treatment duct 11 through the indoor air flow inlet 12, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the air outlet duct 112 is connected to the wind wheel cavity 111, and the exhaust duct 41 is isolated from the wind wheel cavity 111. Therefore, the indoor airflow then enters the air outlet duct 112 from the wind wheel cavity 111, and finally enters the room from the indoor air flow outlet 13, so that the treated indoor airflow can be introduced into the room again.

[0067] For example, the air treatment device 100 can select and switch between the above-mentioned fresh air mode, exhaust mode and internal circulation mode by monitoring the air quality in the indoor environment;

[0068] Of course, the above-mentioned fresh air mode, exhaust mode and internal circulation mode of the air treatment device 100 can also be controlled manually, for example, any one of the above-mentioned three modes can be selected by pressing a button; in addition, when the air treatment device 100 switches to a certain working mode, the user can also choose to exit the working mode by pressing a button, or set the operating time of the air treatment device 100 switching to a certain working mode. After the set time is reached, the air treatment device 100 automatically exits the working mode.

[0069] refer to Figure 4-Figure 12 According to some embodiments of the present invention, the housing component 1 is provided with an exhaust valve 15, and the exhaust valve 15 can move between a first position and a second position; wherein, in the first position, the exhaust valve 15 separates the outlet air duct 112 from the wind wheel cavity 111, and the exhaust air duct 41 is connected to the wind wheel cavity 111; in the second position, the exhaust valve 15 separates the exhaust air duct 41 from the wind wheel cavity 111, and the outlet air duct 112 is connected to the wind wheel cavity 111. In this way, the outlet air duct 112 and the exhaust air duct 41 can be controlled by the movement of a valve, so that the switching of different working modes such as the fresh air mode and the exhaust mode can be realized; the number of valves set can also be reduced, the space occupied by the valve setting can be reduced, and the structure of the air treatment device 100 can be simplified.

[0070] Optionally, the exhaust valve 15 can be provided as a separate component.

[0071] For example, Fig. 9 As shown, the air handling device 100 is in the fresh air mode, the exhaust valve 15 is in the second position, the air outlet duct 112 is connected to the wind wheel cavity 111, and the exhaust duct 41 is connected to the wind wheel cavity 111.

[0072] For example, Fig.10As shown, the air handling device 100 is in the exhaust mode, the exhaust valve 15 is in the first position, the air outlet duct 112 is separated from the wind wheel cavity 111, and the exhaust duct 41 is connected to the wind wheel cavity 111.

[0073] In the description of the present invention, "plurality" means two or more.

[0074] refer to Figure 2-Figure 10 According to some optional embodiments of the present invention, the exhaust valve 15 is rotatable between the first position and the second position. By rotating the exhaust valve 15, the exhaust valve 15 is switched between the first position and the second position, so that the air treatment device 100 can be conveniently switched between the fresh air mode and the exhaust mode. In this way, it is convenient to realize the control of the exhaust valve 15 on the connection and isolation between the air outlet duct 112 and the wind wheel chamber 111, and the connection and isolation between the exhaust duct 41 and the wind wheel chamber 111, and the number of valves can be reduced, the space occupied by the valve setting can be reduced, and the structure of the air treatment device 100 can be simplified.

[0075] refer to Figure 5-Figure 10 According to some optional embodiments of the present invention, the air handling duct 11 includes a connecting cavity 113 located between the wind wheel cavity 111 and the air outlet duct 112, the connecting cavity 113 is connected to the wind wheel cavity 111 through a first connecting port 1131, the connecting cavity 113 is connected to the air outlet duct 112 through a second connecting port 1132, and the connecting cavity 113 is connected to the exhaust duct 41 through a third connecting port 1133. The exhaust valve 15 can move relative to the connecting cavity 113, when the exhaust valve 15 is in the first position, the exhaust valve 15 closes the second connecting port 1132; when the exhaust valve 15 is in the second position, the exhaust valve 15 closes the third connecting port 1133. By providing the connecting cavity 113, the connection between the wind wheel cavity 111 and the air outlet duct 112 can be achieved, and the connection between the wind wheel cavity 111 and the exhaust duct 41 can be achieved. By allowing the exhaust valve 15 to move relative to the connecting chamber 113, the exhaust valve 15 can control the connection and isolation between the air outlet duct 112 and the wind wheel chamber 111, and the connection and isolation between the exhaust duct 41 and the wind wheel chamber 111, thereby reducing the number of valves set, reducing the space occupied by the valve settings, and simplifying the structure of the air treatment device 100.

[0076] For example, Figure 5 , Fig. 9As shown, in the fresh air mode of the air handling device 100, the fresh air valve 141 is in the open state of opening the fresh air inlet 14, and the fresh air flows through the fresh air pipe 3 and enters the air handling duct 11 from the fresh air inlet 14, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side, and then the air flow enters the connecting cavity 113. Since the exhaust valve 15 is in the second position at this time, the exhaust valve 15 closes the third connecting port 1133, and the exhaust valve 15 opens the second connecting port 1132. The wind wheel cavity 111 is connected with the air outlet duct 112 through the connecting cavity 113, and the wind wheel cavity 111 is isolated from the exhaust duct 41. Therefore, the fresh air flow enters the air outlet duct 112 from the connecting cavity 113, and finally enters the room from the indoor air outlet 13, so that the outdoor fresh air can be introduced into the room.

[0077] For example, Figure 6 , Fig.10 As shown, in the exhaust mode, the air handling device 100 has the fresh air valve 141 in a closed state closing the fresh air inlet 14, and the indoor airflow enters the air handling duct 11 through the indoor airflow inlet 12, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side, and then the airflow enters the connecting cavity 113. Since the exhaust valve 15 is in the first position at this time, the exhaust valve 15 closes the second connecting port 1132, and the exhaust valve 15 opens the third connecting port 1133, the air outlet duct 112 is separated from the wind wheel cavity 111, and the exhaust duct 41 is connected to the wind wheel cavity 111 through the connecting cavity 113, so the indoor airflow enters the exhaust duct 41 from the connecting cavity 113, and finally is discharged to the outside through the fresh air pipe 3 from the exhaust duct 41, so that the indoor dirty air can be discharged to the outside.

[0078] For example, when the air treatment device 100 is in the internal circulation mode, the fresh air valve 141 is in a closed state of closing the fresh air inlet 14, and the indoor air enters the air treatment duct 11 through the indoor air flow inlet 12, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side, and then the airflow enters the connecting cavity 113. Since the exhaust valve 15 is in the second position at this time, the exhaust valve 15 closes the third connecting port 1133, and the exhaust valve 15 opens the second connecting port 1132. The outlet duct 112 is connected to the wind wheel cavity 111 through the connecting cavity 113, and the exhaust duct 41 is separated from the wind wheel cavity 111. Therefore, the indoor airflow then enters the outlet duct 112 from the connecting cavity 113, and finally enters the room from the indoor air flow outlet 13, so that the treated indoor airflow can be introduced into the room again.

[0079] Optionally, the first communication port 1131 is disposed at a lower side of the communication cavity 113 , and the second communication port 1132 and the third communication port 1133 are disposed at an upper side of the communication cavity 113 .

[0080] Optionally, the second communication opening 1132 is close to the wind outlet side of the wind wheel cavity 111 , and the third communication opening 1133 is close to the wind outlet side of the wind wheel cavity 111 .

[0081] refer to Figure 3-Figure 7 According to some optional embodiments of the present invention, the shell component 1 includes an air duct volute 16, an air outlet frame 17 and a valve bracket 18 which are independently formed. The air duct volute 16, the air outlet frame 17 and the valve bracket 18 can be independently formed and then assembled, so that the molding mold design of the shell component 1 is simple and the cost is reduced. The air duct volute 16 is formed with a wind wheel cavity 111, an indoor air flow inlet 12 and a fresh air inlet 14, and the air outlet frame 17 is formed with an air outlet duct 112 and an indoor air flow outlet 13. The indoor air flow inlet 12 and the fresh air inlet 14 are located on the air inlet side of the wind wheel cavity 111, and the air outlet frame 17 is located on the air outlet side of the wind wheel cavity 111. This facilitates the smooth flow of air in the air treatment duct 11 to avoid air flow turbulence. The valve bracket 18 is formed with a connecting cavity 113, a first connecting port 1131, a second connecting port 1132 and a third connecting port 1133, and the exhaust valve 15 is rotatably arranged on the valve bracket 18. The exhaust damper 15 can move between a first position and a second position by rotating relative to the valve bracket 18 .

[0082] In this way, by setting the exhaust valve 15 and the valve bracket 18, it is convenient for the air treatment device 100 to switch between different working modes such as fresh air mode and exhaust mode, and the structural design of the air treatment device 100 can be simplified to reduce the occupied space.

[0083] Optionally, the valve bracket 18 is disposed above the air duct volute 16 , and the air outlet frame 17 is at least partially disposed above the valve bracket 18 , and the air outlet frame 17 is at least partially located above the air duct volute 16 .

In this way, the installation relationship between the exhaust valve 15 and the driving mechanism 5 is simple, which facilitates the control of the motion state of the exhaust valve 15 relative to the valve bracket 18, so that the exhaust valve 15 can rotate around the first end. At the same time, the driving mechanism 5 provides a rotational torque for the exhaust valve 15, so that when the exhaust valve 15 is located at the first position or the second position, the second end of the exhaust valve 15 abuts against the inner wall of the valve bracket 18, which can improve the airtightness of the air outlet duct 112 and the exhaust duct 41 when the exhaust valve 15 is located at the first position and the second position, and avoid air leakage at the second end of the exhaust valve 15.

[0086] refer to Figure 8-Figure 11 According to some optional embodiments of the present invention, the driving mechanism 5 includes a driving motor 51, which is arranged outside the connecting cavity 113 and fixed to the valve bracket 18. In this way, the exhaust valve 15 can be controlled to move between the first position and the second position by the driving motor 51. The control method is simple in principle and convenient to control; thus, it is convenient to control the switching between different working modes of the air treatment device 100. In addition, by arranging the driving motor 51 of the driving mechanism 5 outside the connecting cavity 113, the influence of the driving motor 51 on the airflow can be avoided, and the airflow in the connecting cavity 113 can reduce the generation of condensed water on the driving motor 51 and the influence on the use performance of the driving motor 51.

Therefore, in the fresh air mode of the air treatment device 100, the fresh air flow entering the air treatment duct 11 from the fresh air inlet 14 can be humidified by the humidification module and then enter the room through the air outlet duct 112, so that the indoor ambient humidity can be adjusted.

[0091] For example, the water tank part 8 is connected to the lower end of the valve bracket 18 .

[0092] According to some optional embodiments of the present invention, the water tank component 8 and the valve bracket 18 are integrally formed. In this way, the water tank component 8 and the valve bracket 18 can be integrally connected to other components of the air treatment device 100, such as the air duct volute 16 and the humidification module, etc., which can reduce the installation and disassembly steps of the air treatment device 100.

[0093] For example, the water tank component 8 is integrally formed at the lower end of the valve bracket 18 .

A supporting rib 181 extending along the circumference of the second connecting port 1132 is formed on the side of the valve bracket 18 facing the air outlet duct 112. The wet cotton 71 bracket is supported on the supporting rib 181. By cooperating with the bottom wall of the groove 811 and the supporting rib 181, they can jointly support the humidifying component 7, so that the humidifying component 7 is more stably installed on the water tank component 8. In addition, the humidifying component 7 is closely connected to the valve bracket 18, which can avoid air leakage when the airflow enters the air outlet duct 112 from the connecting cavity 113.

In this way, the structural strength of the exhaust valve 15 can be improved, and when the airflow enters the air treatment duct 11 and contacts the exhaust valve 15, the stress deformation degree of the exhaust valve 15 can be reduced. Moreover, the exhaust valve 15 formed as a curved surface can also guide the airflow, so that the airflow can smoothly pass through the exhaust duct 41, thereby enhancing the working effect of the air treatment device 100 in the exhaust mode.

The exhaust valve 15 is bent toward the first side to form an arc, and the reinforcement structure 153 is arranged on the second side of the exhaust valve 15.

The side wall of the second accommodating chamber 202 is formed with a second air inlet 2021 and a second air outlet 2022.

[0101] Among them, the heat exchange and air supply component and the air treatment device 100 can be controlled independently, and the heat exchange and air supply component can be controlled to work alone, the air treatment device 100 can be controlled to work alone, or the heat exchange and air supply component and the air treatment device 100 can be controlled to work simultaneously.

[0111] An internal circulation valve 19 is also provided at the air flow inlet, and the internal circulation valve 19 is used to open and close the indoor air flow inlet 12 to control whether the indoor air flow can enter the air treatment duct 11.

[0112] like Fig. 9 As shown, the shell component 1 is also provided with an exhaust valve 15. Specifically, the exhaust valve 15 is rotatably arranged on the valve bracket 18. The exhaust valve 15 is used to cooperate with the second connecting port 1132 and the third connecting port 1133 to control the connection and isolation between the wind wheel cavity 111 and the air outlet duct 112 and the wind wheel cavity 111 and the exhaust duct 41.

[0113] like Figure 11-Figure 12 As shown, the exhaust valve 15 is formed into an arc-shaped plate-like structure, having a first side and a second side arranged in the thickness direction, a first end and a second end arranged in the width direction, and a third end and a fourth end arranged in the length direction.

[0114] When the exhaust valve 15 is rotatably connected to the valve bracket 18, the first side of the exhaust valve 15 faces the second opening of the valve bracket 18, and the second side of the exhaust valve 15 faces the third opening of the valve bracket 18.

[0115] like Figure 5-Figure 6 , Figure 9-10 As shown, the exhaust valve 15 has a first position and a second position. When the exhaust valve 15 is in the first position, the exhaust valve 15 is located at the second opening, and the exhaust valve 15 makes the exhaust duct 41 connected with the connecting chamber 113 and the wind wheel chamber 111 through the third opening, and the air outlet duct 112 is separated from the connecting chamber 113 and the wind wheel chamber 111; when the exhaust valve 15 is in the second position, the exhaust valve 15 is located at the third opening, and the exhaust valve 15 makes the air outlet duct 112 connected with the connecting chamber 113 and the wind wheel chamber 111 through the second opening, and the exhaust duct 41 is separated from the connecting chamber 113 and the wind wheel chamber 111.

[0116] like Figure 4-Figure 7As shown, further, the air treatment device 100 also includes a humidification module, and the humidification module includes a water tank 6, a humidification component 7 and a water tank component 8. The water tank 6 is connected to the upper part of the water tank component 8, and the water tank component 8 is connected to the lower part of the humidification component 7.

[0117] A support rib 181 extending along the circumference of the second communication port 1132 is formed on one side of the valve bracket 18 facing the air outlet duct 112, and the wet cotton 71 is supported on the support rib 181. The air outlet frame 17, the humidifying component 7, and the valve bracket 18 are connected in sequence.

[0118] In this embodiment, the air treatment device 100 has multiple working modes, such as a fresh air mode, an exhaust air mode, and an internal circulation mode. Figure 4-Figure 12 Describe the different operating modes.

[0119] like Figure 5 , Fig. 9 As shown, when the air treatment device 100 is in the fresh air mode, the fresh air valve 141 is in an open state to open the fresh air inlet 14, and the indoor circulation valve 19 is in a closed state to close the indoor air flow inlet 12. The fresh air flows through the fresh air pipe 3 and enters the air treatment duct 11 from the fresh air inlet 14, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the exhaust valve 15 is in the second position, the outlet duct 112 is connected with the wind wheel cavity 111, and the exhaust duct 41 is separated from the wind wheel cavity 111. Therefore, the fresh air flow then enters the connecting cavity 113 from the wind wheel cavity 111, and then from the connecting cavity 113 through the second opening, and passes through the humidification module into the outlet duct 112, and finally enters the room from the indoor air flow outlet 13, so that outdoor fresh air can be introduced into the room.

[0120] For example, when the air treatment device 100 is in the fresh air mode, the fresh air valve 141 is in the open state of opening the fresh air inlet 14, and the indoor circulation valve 19 is also in the open state of opening the indoor air flow inlet 12. The fresh air flows through the fresh air pipe 3 and enters the air treatment duct 11 from the fresh air inlet 14, and the indoor air flows through the indoor air flow inlet 12. The fresh air flow and the indoor air flow both flow through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the exhaust valve 15 is in the second position, the air outlet duct 112 is connected with the wind wheel cavity 111, and the exhaust duct 41 is separated from the wind wheel cavity 111. The fresh air flow and the indoor air flow both enter the connecting cavity 113 from the wind wheel cavity 111, and then enter the air outlet duct 112 from the connecting cavity 113 through the second opening and through the humidification module, and finally enter the room from the indoor air flow outlet 13, so that the outdoor fresh air and the treated indoor air flow can be introduced into the room.

[0121] For example, Figure 6 , Fig.10 As shown, in the exhaust mode, the air treatment device 100 has the fresh air valve 141 in a closed state closing the fresh air inlet 14, and the indoor circulation valve 19 in an open state of the indoor air flow inlet 12. The indoor airflow enters the air treatment duct 11 through the indoor air flow inlet 12, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the exhaust valve 15 is in the first position, the air outlet duct 112 is separated from the wind wheel cavity 111, and the exhaust duct 41 is connected to the wind wheel cavity 111. Therefore, the indoor airflow then enters the connecting cavity 113 from the wind wheel cavity 111, and then enters the exhaust duct 41 from the connecting cavity 113 through the third opening, and finally is discharged from the exhaust duct 41 to the outside through the fresh air pipe 3, so that the indoor dirty air can be discharged to the outside.

[0122] For example, when the air treatment device 100 is in the internal circulation mode, the fresh air valve 141 is in a closed state to close the fresh air inlet 14, and the indoor circulation valve 19 is in an open state to open the indoor air flow inlet 12. The indoor airflow enters the air treatment duct 11 through the indoor air flow inlet 12, and then flows through the wind wheel cavity 111 from the air inlet side to the air outlet side. At this time, the exhaust valve 15 is in the first position, the air outlet duct 112 is connected to the wind wheel cavity 111, and the exhaust duct 41 is isolated from the wind wheel cavity 111. Therefore, the indoor airflow then enters the connecting cavity 113 from the wind wheel cavity 111, passes through the humidification module air outlet duct 112, and finally enters the room from the indoor air flow outlet 13, so that the indoor airflow treated with humidification can be introduced into the room again.
