In the drawings, identical components are indicated by identical reference number. 
         [0027]    As shown in  FIG. 1 , the wall hanging air conditioner of the present invention includes a panel  1 . An air outlet  10  is provided, in the panel  1 , and a swing blade mechanism  3  is provided at a lower portion  102  of the air outlet. 
         [0028]    In the prior art, the swing device for is generally mounted at the upper portion  101  of the air outlet  10 . However, since the air outlet has a larger air output at the lower portion  102  than at the upper portion, it is difficult for the swing device located at the upper portion of the air outlet  10  to perform an effective sweep for the air outgoing from the lower portion  102  of the air outlet, and the air discharging angle of the air conditioner is also limited. In the present invention, the swing blade mechanism  3  is provided at the lower portion  102  of the air outlet, which can efficiently change the air discharging direction, and can improve the air discharging angle under a relatively large air force, thereby increasing the flowing range of the air discharged from the air conditioner indoors and increase the comfortable feeling of people. 
         [0029]    As shown in  FIGS. 2 and 3 , in order to make the swing blade mechanism  3  achieve a better swing angle and be detached or mounted flexibly, preferably, the swing blade mechanism  3  may include a base  31 , a transmission mechanism  33 , and a plurality of swing blades  35  connected in a transmission manner to the transmission mechanism  33 . One end of the transmission mechanism  33  is connected in a transmission manner to a driving output end of a swine motor of the wall hanging air conditioner. The swing blades  35  are driven to swing left or right under the driving of the swing motor. The plurality of swing blades  35  may be provided on the base  31  in sequence and at an equal interval. 
         [0030]    In order that the swing blades  35  can be detached or mounted more flexibly, each swing blade  35  may include a blade body  351 , a blade seat  353 , and an elastic connecting part  355  connecting the blade body  351  and the blade seat  353 . The blade seat  353  fixedly connected to an air outlet seat of the lower portion  102  of the air outlet  10 . 
         [0031]    In order that the swing blade  35  can be easily deformed to better change the air guide angle, the blade body  351  can swing at a larger angle and the swing resistance can be reduced, the elastic connecting part  355  may be of an elongated shape, and an upper end of the elastic connecting part  355  may be connected to an inner edge of the blade body  351 . 
         [0032]    Preferably, in the present embodiment, the upper end of the elastic connecting part  355  may be connected to an upper end of the inner edge of the blade body  351 , to efficiently reduce the connection portion between the elastic connecting part  355  and the blade body  351  and increase the swing flexibility of the blade body  351 . 
         [0033]    The blade body  351  may be fixedly connected to the base  31  via the elastic connecting part  355  and the blade seat  353 . The elastic connecting part  355  and the blade body  351  may be made integrally, or be formed separately. The elastic connecting part  355  and the blade seat  353  may be made integrally, or be formed separately. The blade seat  353  may be fixedly connected to the base  31  in an inserted coupling manner, and accordingly, the base  31  may be provided with the corresponding number of grooves. Generally, the blade body  351  may be made of an elastic material that can be bent, and the blade body  351  can be driven by the transmission mechanism  33  to swing left of right under the elastic force. 
         [0034]    In order that the swing blade mechanism  3  can be detached for cleaning or maintaining, each blade body  351  may be connected to the transmission mechanism  33  in a snap-fit coupling manner. The transmission mechanism  33  may be a connecting rod, and each swing blade  35  may be connected to the connecting rod in a snap-fit coupling manner. The connecting rod may be provided with a plurality of grooves, and each blade body  351  may be correspondingly provided at a side thereof with a blade notch  352 , and the blade notch  352  of each blade body  351  is fitted with corresponding groove of the connecting rod. 
         [0035]    The connecting rod may also be provided with a plurality of ring-shaped friction parts, and the blade notch  352  of each blade body  351  may be closely engaged with the corresponding friction part of the connecting rod. So that the blade body  351  may be driven by the connecting rod to swing left or right under the friction force. 
         [0036]    The blade notch  352  may be provided at a middle portion of an outer edge of each blade body  351  and is located at the opposite side of the elastic connecting part  355 . 
         [0037]    When the swing blade mechanism  3  is operated, the connecting rod is rotated under the drive of the driving output end of the swing motor, and thus drives the blade body  351  of each swing blade  35  to swing left or right to perform the air sweep, thereby achieving the adjustment of a relatively large air discharging angle. 
         [0038]    As shown in  FIG. 4 , in order to further facilitate the adjustment of the swing angle of the swing blades  35 , and also to avoid the circumstance in which the direction of the air can not be adjusted due to the breakdown of the swing motor, the swing blade mechanism  3  may further includes a manual adjusting device. The manual adjusting device includes a rotatable shaft  32  and a rack portion. The rotatable shaft  32  which includes a manual force exerting portion  321  and a pinion portion  322 , is rotatablely provided on the base  31  The rack portion is provided on the connecting rod and engages with the pinion portion  322 . 
         [0039]    In order to facilitate applying a force to the manual adjusting device, the manual force exerting portion  321  may be a polyhedral prism portion provided at a middle portion of the rotatable shaft  32 , and the pinion portion  322  may be provided at an upper end of the rotatable shaft  32 . 
         [0040]    When it needs to adjust the swing angle of the swing blade  35  manually, the polyhedral prism portion may be rotated manually such that the pinion portion  322  is rotated accordingly, so as to drive the connecting rod to move left or right through the engagement between the pinion of an upper end of the pinion portion and the rack of the connecting rod, thereby achieving the leftward or rightward swing of the swing, blade  35 . 
         [0041]    The manual force, exerting portion  321  may also be configured as a handle mounted on the rotatable shaft  32 . The rotatable shaft  32  may he rotated at an angle by operating the handle, such that the connecting rod moves by a distance in a longitudinal direction, thereby achieving the adjustment of the air direction via the swing blades  35  connected to the connecting rod. 
         [0042]    In order that the swing blade mechanism  3  can be stably mounted on the air outlet seat of the lower portion  102  of the air outlet  10  and can be easily detached, preferably, the swing blade mechanism  3  may further include a sinking step portion  37  which is at least provided at a longitudinal edge portion of the base  3 . 1 . A lower side of the sinking step portion  37  may be detachably fixed on the air outlet seat of the lower portion of the air outlet  10 .
