Referring to fig. 1, fig. 2, fig. 4, and fig. 6, an air treatment apparatus 100 is provided. The air processing device 100 includes a housing 10, a first fan, a second fan 20, a driving motor 15, and a rotating shaft 50. The air conditioner is characterized in that a containing cavity is formed in the shell 10, a first fan is arranged in the containing cavity, a first air outlet is formed in the shell 10 and communicated with the containing cavity, and the first fan is used for generating air flow flowing out of the first air outlet. The second fan 20 is movably installed at the first air outlet. The rotating shaft 50 is connected with the second fan 20 and the housing 10, the driving motor 15 includes 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 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 to the second fan 20 is a connecting end, and the connecting end is spaced from the rotating shaft 50.

Referring to fig. 3 to 6, it should be noted that the driving motor 15 is connected to the second fan 20 through the link assembly 10c, rather than being directly connected to the rotating shaft 50. Specifically, when the driving motor 15 is operated, the driving motor 15 provides an upward thrust to the second fan 20 through the connecting rod assembly 10c to push the second fan 20 to move around the rotating shaft 50. If the driving motor 15 is directly connected to the rotating shaft 50, although the effect of driving the second fan 20 to rotate can also be achieved. However, in this arrangement, the required driving force is large and a large-sized motor is required when the rotational torque is the same. This results in a large overall size of the air treatment device 100, which is disadvantageous for miniaturization thereof.

Specifically, the moment represents a physical quantity of a rotational effect generated when a force acts on an object. The vector product of the force and the moment arm is the moment. The moment is a vector (vector). The magnitude of the moment of force at a point is the length of the perpendicular drawn from the point to the line of action of the force (i.e., the moment arm) multiplied by the magnitude of the force, and the direction is determined by the right-handed helix rule of the moment, perpendicular to the plane formed by the perpendicular and the force. The force to a certain axis moment is equal to the projection of the force to the moment of any point on the axis. The air treatment device 100 of the present invention increases the force arm under the condition that the rotation torque required for rotating the second fan 20 around the rotation shaft 50 is similar, so as to reduce the required driving force and correspondingly reduce the required size of the driving motor 15.

In an alternative embodiment, the driving motor 15 may also be connected to the second fan 20 through a rack and pinion mechanism or a ball screw mechanism. However, through many experiments, although the rack and pinion mechanism or the ball screw mechanism objectively reduces the required driving force and plays a labor saving role in comparison with the case where the driving motor 15 is directly connected to the rotating shaft 50. However, through multiple experiments, it is found that compared with the connecting rod assembly 10c, the rack-and-pinion mechanism or the ball screw mechanism has the defects of large volume, poor attractiveness, difficulty in flexible installation and the like.

Referring to fig. 1 and fig. 2, in order to achieve the multi-functional air outlet effect, the air processing apparatus 100 is provided with 2 fans, that is, a first fan and a second fan 20. The two can work independently or in combination. In an alternative embodiment, the first fan is a centrifugal fan, and the second fan 20 is an axial fan. Specifically, the first fan is disposed in the accommodating cavity, a first air inlet of the first fan is disposed on the side of the casing 10, and a first air outlet of the first fan is disposed above the casing 10, i.e., at the opening of the accommodating cavity. When the first fan works, outside air flows upwards flow out of the first air outlet after entering the accommodating cavity from the first air inlets on the two sides. 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 respectively disposed at the upper and lower sides of the second fan 20. Optionally, an air outlet grille is further disposed in the air outlet channel 16.

The second fan 20 can be turned over relative to the first air outlet, and the relative position of the first air outlet and the second air outlet can be adjusted. In order to avoid the mutual influence of the air flows of the first fan and the second fan 20 when the two fans work together. In an alternative embodiment, the second fan 20 has a first position covering the first outlet and a second position forming an angle with the first outlet. When the first fan is turned on and the second fan 20 is turned on at the same time, the second fan 20 is adjusted to a second position. Like this, the second air intake with be formed with certain contained angle between the first air outlet, by during the wind majority that first air outlet flowed can not directly get into the second air intake, the interference the work of second fan 20. In addition, the second fan 20 can also guide the flow direction of the airflow blown out from the first air outlet, so that the first fan generates an airflow in an obliquely upward direction. When the first fan or the second fan 20 is turned on alone, the position of the second fan 20 can be adjusted, so as to adjust the flow direction of the air flow blown by the air processing device 100.

In an alternative embodiment, the second fan 20 further comprises a rotation connection 123 in addition to the second end 122, and the rotation connection 123 is rotatably connected to the housing 10. When the driving motor 15 moves, the position where the second fan 20 is connected to the second end 122 and the rotation connection portion 123 move relatively, so as to turn over the second fan 20.

On the basis of the above alternative embodiment, if the driving motor 15 is directly connected to the second fan 20 through the first connecting rod 12. The motion 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 10 c.
