In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel schemes, for example, "A and / or B" includes A scheme, or B scheme, or A and B schemes. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, nor within the scope of protection required by the present application.

[0038] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 , the present application provides an air treatment device 100. The air treatment device 100 comprises a shell 10, a first fan, a second fan 20 and a driving motor 15, a rotating shaft 50. The shell 10 is provided with a containing cavity, the first fan is arranged in the containing cavity, the shell 10 is provided with a first air outlet, the first air outlet is communicated with the containing cavity, and the first fan is used for generating airflow flowing out of the first air outlet. The second fan 20 is movably installed at the first air outlet. The rotating shaft 50 connects the second fan 20 and the shell 10, the driving motor 15 comprises a driving motor 15 and a connecting rod assembly 10c, one end of the connecting rod assembly 10c is connected with the driving motor 15, and the other end of the connecting rod assembly 10c is connected with the second fan 20, so as to drive the second fan 20 to rotate around the rotating shaft 50. The end of the connecting rod assembly 10c connected with the second fan 20 is a connecting end, and the connecting end is arranged at intervals with the rotating shaft 50.

[0039] Please refer to Figures 3 to 6 , it is worth noting that the driving motor 15 is connected with the second fan 20 through the connecting rod assembly 10c, rather than directly connected with the rotating shaft 50. Specifically, when the driving motor 15 operates, the driving motor 15 provides an upward thrust to the second fan 20 through the connecting rod assembly 10c, so as to drive the second fan 20 to move around the rotating shaft 50. If the driving motor 15 is directly connected with the rotating shaft 50, although the effect of driving the second fan 20 to rotate can be achieved. However, in this way, under the condition of the same rotating torque, the required driving force is larger, and a larger size motor is required. Thus, the overall volume of the air treatment device 100 is larger, which is not conducive to the miniaturization thereof.

[0040] Specifically, the moment represents the physical quantity of the rotating effect generated by the force acting on the object. The vector product of the force and the force arm is the moment. The moment is a vector. The size of the moment of force on a point is the length of the perpendicular line from the point to the action line of the force (i.e. the force arm) multiplied by the size of the force, and the direction is determined by the right-hand screw rule of the moment perpendicular to the plane formed by the perpendicular line and the force. The size of the moment of force on an axis is equal to the projection of the moment of force on any point on the axis on the axis. The air treatment device 100 proposed in the present application can increase the force arm under the condition that the required moment of rotation of the second fan 20 rotating around the rotation axis 50 is similar, thereby reducing the required driving force and the size of the driving motor 15.

[0041] In an optional embodiment, the driving motor 15 can also be connected to the second fan 20 through a gear rack mechanism or a ball screw mechanism. However, through repeated experiments, although the gear rack mechanism or the ball screw mechanism objectively reduces the required driving force compared with the direct connection of the driving motor 15 to the rotation axis 50, it plays a labor-saving role. However, through repeated experiments, it is found that compared with the connecting rod assembly 10c, the gear rack mechanism or the ball screw mechanism has the defects of large size, not beautiful, difficult to install flexibly, etc.

[0042] Please refer to Figure 1 、 Figure 2 To achieve the effect of multifunctional air outlet, the air treatment device 100 is provided with two fans, i.e. the first fan and the second fan 20. The two can work separately or in combination. In an optional embodiment, the first fan is a centrifugal fan, and the second fan 20 is an axial flow fan. Specifically, the first fan is arranged in the containing cavity, and the first air inlet of the first fan is arranged on the side of the shell 10, and the first air outlet of the first fan is arranged above the shell 10, i.e. at the opening of the containing cavity. When the first fan works, the external airflow enters the containing cavity from the two sides of the first air inlet and flows out from the first air outlet upwards. The second fan 20 has a second air inlet and a second air outlet, and the second air inlet and the second air outlet are arranged on the upper and lower sides of the second fan 20, respectively. Optionally, the air outlet channel 16 is also provided with an air outlet grille.

[0043] The second fan 20 can be flipped relative to the first air outlet, i.e. the relative positions of the first air outlet and the second air outlet can be adjusted. In this way, when the first fan and the second fan 20 work together, the air flows of the two will not affect each other. In an optional embodiment, the second fan 20 has a first position covering the first air outlet, and a second position forming an angle with the first air outlet. When the first fan is turned on and the second fan 20 is also turned on, the second fan 20 is adjusted to the second position. In this way, the second air inlet and the first air outlet form an angle, and most of the air flowing out of the first air outlet will not directly enter the second air inlet, thereby interfering with the work of the second fan 20. In addition, the second fan 20 can also guide the flow direction of the air flowing out of the first air outlet, so that the first fan generates air flow in a diagonal upward direction. When the first fan or the second fan 20 is turned on alone, the position of the second fan 20 can also be adjusted, so as to adjust the flow direction of the air blown out by the air treatment device 100.

[0044] On the basis of the above embodiment, the angle between the second fan 20 and the first air outlet can be set according to needs. In addition, a plurality of different angles can also be preset to realize air supply in different directions by the first fan and the second fan 20.

[0045] Please refer to Figure 7 In an optional embodiment, the shell 10 includes a shell body 10a and an air outlet assembly 10b, the accommodating cavity is arranged in the shell body 10a, the air outlet assembly 10b includes an air outlet channel 16, the first air outlet is formed in the air outlet assembly 10b, the air outlet channel 16 communicates the accommodating cavity and the first air outlet, the driving motor 15 is installed outside the air outlet channel 16, and the driving motor 15 is arranged below the first air outlet.

[0046] The air outlet assembly 10b is provided to facilitate the installation of the driving motor 15 and the second fan 20. Specifically, the shell body 10a is formed with an installation opening in communication with the accommodating cavity, one end of the air outlet channel 16 extends into the installation opening, and the other end forms the first air outlet. The first air outlet is outwardly extended to form an installation plate. The installation plate is connected to the edge of the installation opening. The driving motor 15 is arranged on the lower side of the first air outlet, i.e. the side of the installation plate facing the accommodating cavity, and the installation plate on the upper side of the first air outlet is provided with a hole for mounting the rotating shaft 50, and the second fan 20 is connected to the installation plate through the rotating shaft 50. Since there is a certain distance between the position connected by the connecting rod assembly 10c and the mounting position of the rotating shaft 50, the required driving force is effectively reduced, thereby effectively reducing the volume of the driving motor 15. At the same time, the driving motor 15 is hidden below the second fan 20, making the air treatment device 100 more beautiful.

[0047] Please refer to Figures 8 to 9 In an optional embodiment, the connecting rod assembly 10c includes a first connecting rod 12, the first connecting rod 12 has oppositely arranged first and second ends 121 and 122, the first end 121 is connected to the second fan 20, the second end 122 is connected to the driving motor 15, the shell 10 is provided with a rotating shaft hole 112 and a limiting guide rail 111, the first end 121 is rotatably arranged in the rotating shaft hole 112, the second end 122 is provided with a limiting protrusion 122a corresponding to the limiting guide rail 111, and the driving motor 15 drives the limiting protrusion 122a to move along the limiting guide rail 111, thereby driving the second fan 20 to rotate around the rotating shaft 50, so that the second fan 20 is flipped relative to the first air outlet.

[0048] In this way, relative to the shell 10, the driving motor 15 drives the second end 122 of the first connecting rod 12 to rotate around the first end 121, and a connecting portion 123 is arranged between the first end 121 and the second end 122. To make the rotation more stable, the connecting portion 123 is arranged in an arc shape. And the first end 121 is fixedly connected to the second fan 20, i.e. in the process of rotating the first connecting rod 12, the second fan 20 is lifted up to realize the flipping of the second fan 20 relative to the first air outlet. In an optional embodiment, in addition to being fixedly connected to the second end 122, the second fan 20 also includes a rotating connecting portion 123, and the rotating connecting portion 123 is rotatably connected to the shell 10. When the driving motor 15 moves, the position of the second fan 20 connected to the second end 122 and the rotating connecting portion 123 relatively move to realize the flipping of the second fan 20.

[0049] On the basis of the previous optional embodiment, if the driving motor 15 is directly connected to the second fan 20 through the first connecting rod 12. The movement track of the first connecting rod 12 depends on the driving of the driving motor 15 and the preset position of the connecting rod assembly 10c. Thus, in the movement process, it is easy to appear rotation jamming or the situation of the connecting rod assembly 10c tilting. That is, it is not conducive to realize the stability of the rotation of the second fan 20. Therefore, the setting of the limiting guide rail 111 and the limiting protrusion 122a is necessary. Thus, the setting limits the movement track of the first connecting rod 12, reduces the situation of rotation tilting and jamming.

[0050] In an optional embodiment, one side of the second end 122 forms the limiting protrusion 122a, and the other side forms the hinged hole 122b. The connecting rod assembly 10c further comprises a second connecting rod 13 and a third connecting rod 14. The first connecting rod 12 is connected to the driving motor 15 through the second connecting rod 13 and the third connecting rod 14 in turn. The first connecting rod 12 is hinged through the hinged hole 122b and the second connecting rod 13, and the second connecting rod 13 and the third connecting rod 14 are hinged. The driving motor 15 and the third connecting rod 14 are detachably connected. Hinge is a relatively stable rotary connection mode. It is helpful for the relative movement of two objects under certain conditions. In an optional embodiment, one end of the third connecting rod 14 is connected to the driving motor 15, and the other end is hinged with the second connecting rod 13. So that the motor drives the third connecting rod 14 (also called driving rod) to rotate, and the third connecting rod 14 drives the second connecting rod 13 to rotate, so that the first connecting rod 12 moves, and also drives the limiting protrusion 122a to move along the limiting track. Specifically, the driving motor 15 drives the second fan 20 to rotate relative to the first air outlet through a plurality of hinged connecting rods. Thus, under the premise of ensuring the stability of the movement, the distance between the driving motor 15 and the second fan 20 is increased, so as to further reduce the driving force required for rotation, so as to achieve the effect of reducing the size of the driving motor 15.

[0051] Please refer to Figures 10 to 11In an alternative embodiment, one side of the first end 121 is formed with a rotating shaft column 121a, and the other side is formed with a pin joint hole 121b. The rotating shaft column 121a is rotatably arranged in the rotating shaft hole 112, and the second fan 20 is pin-jointed with the first end 121 through the pin joint hole 121b. The pin joint hole 121b is polygonal. The second fan 20 is provided with a corresponding pin column. The pin column 21 extends into the pin joint hole 121b to realize the pin joint of the second fan 20 and the first transmission shaft. Pin joint is a commonly used fixed connection mode. It has the characteristics of easy maintenance and replacement. The rotating shaft column 121a and the inner wall of the rotating shaft hole 112 are gap-fitted, and when the driving motor 15 operates, the rotating shaft column 121a can rotate in the rotating shaft hole 112, thereby driving the second fan 20 to rotate.

[0052] Please refer to Figures 12 to 13 In an alternative embodiment, the rotating shaft column 121a is formed with a limiting ring 121c in the middle, and the rotating shaft hole 112 is formed with a limiting groove corresponding to the limiting ring 121c. The limiting ring 121c and the limiting groove are gap-fitted. Specifically, the rotating shaft hole 112 has a first hole section and a second hole section. The second hole section is arranged in the middle of the first hole section, and the diameter of the first hole section is smaller than that of the second hole section. The limiting ring 121c is located in the second hole section. In this way, the axial displacement between the rotating shaft column 121a and the rotating shaft hole 112 during rotation can be prevented, thereby preventing the second fan 20 from moving left and right during rotation.

[0053] Please refer to Figure 7 The air outlet assembly 10b further includes a mounting box 11. The mounting box 11 is arranged outside the air outlet channel 16, the driving motor 15 is accommodated in the mounting box 11, and the rotating shaft hole 112 and the limiting guide rail 111 are arranged on the mounting box 11. The mounting box 11 can be directly formed on the shell body 10a or on the air outlet channel 16. The mounting box 11 is arranged on the air outlet assembly 10b, and the air outlet assembly 10b is detachably arranged at the opening of the shell body 10a. In this way, the driving motor 15 is easy to maintain and replace.

On the basis of the above-mentioned alternative embodiment, the air treatment device 100 comprises two mounting boxes 11, and the two mounting boxes 11 are arranged on the two opposite sides of the air outlet channel 16, respectively. Further, the two mounting boxes 11 are arranged symmetrically, and the two mounting boxes 11 are connected to the two opposite ends of one side of the second fan 20 or are connected to the two opposite sides of the second fan 20. In this way, the rotation of the second fan 20 is facilitated. It is worth noting that the rotation shaft can be arranged on the air outlet channel 16 or can be arranged on the shell body 10a. In order to make the rotation of the second fan 20 more stable, the air treatment device 100 comprises at least two mounting boxes 11, and the two mounting boxes 11 are arranged at the two ends of the rotation shaft 50.

[0055] Please refer to Figure 7 In an alternative embodiment, the mounting box 11 comprises a first mounting cavity 11a and a second mounting cavity 11b, the first mounting cavity 11a and the second mounting cavity 11b are arranged on the upper side and the lower side of the first air outlet, respectively, the first connecting rod 12 is arranged in the first mounting cavity 11a, and the driving motor 15 is arranged in the second mounting cavity 11b.

The mounting box 11 further comprises a wire passing portion, and the wire passing portion is provided with a wire passing groove 113. The wire passing groove 113 is used for the wire routing of the motor, the display screen, the voice and other devices. In an alternative embodiment, in order to facilitate the wire routing, the wire passing groove 113 and the rotation shaft hole 112 are coaxially arranged.
