A T-shaped rod 29 is fixedly connected to the third spring 28, and one end of the T-shaped rod 29 passes through the side wall of the receiving groove and is inserted on the annular plate 26. When it is not necessary to discharge the cold air or hot air of the air-conditioning body 1 from the first air outlet 5 of the exhaust pipe 4, the staff manually pushes the T-shaped rod 29 to move the T-shaped rod 29. During the movement of the T-shaped rod 29, when one end of the T-shaped rod 29 detaches from the annular plate 26, that is, there is no connection between the annular plate 26 and the arc-shaped baffle 27, that is, the cold air or hot air of the air-conditioning body 1 is blocked from being discharged from the first air outlet 5.

[0041] A first threaded hole is provided at the bottom end of the discharge pipe 4, and a first external thread is provided on the circumferential outer wall of the connecting pipe 12. The first external thread matches the first threaded hole. When the position of the support block 13 needs to be adjusted, the staff manually rotates the support block 13 to realize the rotation of the connecting pipe 12. During the rotation of the connecting pipe 12, the position of the connecting pipe 12 relative to the discharge pipe 4 is adjusted, that is, the position of the support block 13 is adjusted.

[0042] A connecting tube 30 is arranged between the pad 14 and the support block 13, and a second external thread and a third external thread are respectively provided on the circumferential outer walls at both ends of the connecting tube 30, and a second threaded hole is provided on the side wall of the cavity. A storage cavity is provided in the pad 14, and a third threaded hole is provided on the side wall of the storage cavity. The second external thread cooperates with the second threaded hole, and the third external thread cooperates with the third threaded hole. The storage cavity is communicated with the second air outlet 15. When it is necessary to connect the pad 14 to the support block 13, the staff places one end of the connecting tube 30 at the second threaded hole of the cavity and manually rotates the connecting tube 30. During the rotation of the connecting tube 30, the connecting tube 30 is connected to the support block 13. Then, the other end of the connecting tube 30 is placed at the third threaded hole of the pad 14, and the connecting tube 30 is manually rotated to realize the connection between the connecting tube 30 and the pad 14, thereby realizing the connection between the pad 14 and the support block 13 through the connecting tube 30.

[0043] A soft pad 31 is arranged above the pad 14, a soft frame 32 is fixedly connected between the soft pad 31 and the pad 14, the lower surface of the soft pad 31 is elastically connected to the pad 14, an exhaust hole 34 is opened on the soft pad 31, a filter 38 is fixedly connected to the side wall of the exhaust hole 34, a fixing rod 35 is fixedly connected to the lower surface of the filter 38, a blocking block 36 is fixedly connected to the lower end of the fixing rod 35, and the blocking block 36 cooperates with the second air outlet 15. When the user's foot steps on the soft pad 31, the soft pad 31, the soft frame 32 and the elastic column 33 are all made of rubber elastic soft material. Therefore, when the user's foot steps on the soft pad 31, the soft pad 31 moves downward. During the downward movement of the soft pad 31, the blocking block 36 moves downward through the fixing rod 35. When the blocking block 36 is separated from the second air outlet 15, it is convenient for the gas to be discharged from the second air outlet 15 and the exhaust hole 34 to the foot, thereby increasing the comfort of the foot. At the same time, due to the provision of the filter net 38, less impurities and dust enter through the exhaust hole 34.

[0044] An elastic column 33 is fixedly connected to the lower surface of the soft pad 31 , and the lower end of the elastic column 33 is fixedly connected to the pad 14 .

[0045] An airbag 37 is arranged between the soft pad 31 and the pad 14, and the air outlet hole of the airbag 37 is arranged toward the filter net 38. The airbag 37 is squeezed in the process of the soft pad 31 moving downward, and the gas in the airbag 37 is discharged in the process of squeezing the airbag 37. Since the air outlet hole of the airbag 37 is arranged toward the filter net 38, the gas in the airbag 37 is blown toward the filter net 38 to blow away the dust on the filter net 38, and less dust is attached to the upper surface of the filter net 38.

[0046] Working principle: The staff places one of the air guide shells 16 at one end of the other air guide shell 16, and then places the lower connecting plate 21 below the connection between the two air guide shells 16, and places the upper connecting plate 20 above the connection between the two air guide shells 16. When the upper connecting plate 20 moves relative to the air guide shell 16, the push rod 23 is used to realize the downward movement of the cross bar 24, and the baffle 19 is moved downward in the process of the downward movement of the cross bar 24. In the process of the downward movement of the baffle 19, the port of the air guide shell 16 is opened to facilitate the air to communicate between the air guide shells 16.

[0047] The staff manually rotates the support block 13 to realize the rotation of the connecting pipe 12 . During the rotation of the connecting pipe 12 , the position of the connecting pipe 12 relative to the discharge pipe 4 is adjusted, that is, the position of the support block 13 is adjusted.

[0048] The staff places one end of the connecting tube 30 at the second threaded hole of the cavity and manually rotates the connecting tube 30. During the rotation of the connecting tube 30, the connecting tube 30 is connected to the support block 13. Then, the other end of the connecting tube 30 is placed at the third threaded hole of the pad 14, and the connecting tube 30 is manually rotated to achieve the connection between the connecting tube 30 and the pad 14, thereby achieving the connection between the pad 14 and the support block 13 through the connecting tube 30.

[0049] When the cold air or hot air in the exhaust pipe 4 is needed, the air conditioner body 1 works to realize the flow of gas from the air duct 2 and the air guide duct 3 to the exhaust pipe 4, and the staff manually pushes the T-shaped rod 29 to move the T-shaped rod 29. During the movement of the T-shaped rod 29, when one end of the T-shaped rod 29 detaches from the annular plate 26, that is, there is no connection between the annular plate 26 and the arc-shaped baffle 27, and when the arc-shaped baffle 27 is not located at the corresponding position of the first air outlet 5, the cold air or hot air is discharged from the first air outlet 5 of the exhaust pipe 4.

[0050] Since the air conditioner body 1 can easily make the indoor air dry during operation, the staff adds clean water to the storage tank 6 during use, and the clean water in the storage tank 6 flows from the water outlet to the liquid carrying plate 8 in the water storage tank 7. When the water on the liquid carrying plate 8 accumulates more and more, the liquid carrying plate 8 moves downward due to the gravity of the liquid. In the process of the liquid carrying plate 8 moving downward, the blocking block 11 moves downward through the connecting rod 9 and the connecting rod 10. When the blocking block 11 is located in the water outlet of the storage tank 6, the water in the storage tank 6 is blocked from flowing out by the blocking block 11. Since the water storage tank 7 of the first air outlet 5 stores moisture, when the cold air or the warm air is discharged from the first air outlet 5, the moisture contained in the indoor air is increased.

[0051] When the user's foot steps on the soft pad 31, since the soft pad 31, the soft frame 32 and the elastic column 33 are all made of rubber elastic soft material, when the user's foot steps on the soft pad 31, the soft pad 31 moves downward, and during the downward movement of the soft pad 31, the blocking block 36 moves downward through the fixing rod 35. When the blocking block 36 is detached from the second air outlet 15, it is convenient for the gas to be discharged from the second air outlet 15 and the exhaust hole 34 to the foot, thereby increasing the comfort of the foot. At the same time, due to the provision of the filter net 38, less impurities and dust enter through the exhaust hole 34.

[0052] In the process of the soft pad 31 moving downward, the airbag 37 is squeezed, and the gas in the airbag 37 is discharged in the process of squeezing the airbag 37. Since the air outlet of the airbag 37 is arranged toward the filter 38, the gas in the airbag 37 is blown toward the filter 38 to blow out the dust on the filter 38, and less dust is attached to the upper surface of the filter 38.
