[0029] As shown Figures 1-10 in the figure, an air purifier with a switchable blowing mode includes a purifier body 1. A rectangular air outlet housing 2 is provided on the front side of the purifier body 1. An air outlet grid 3 is provided on the front side of the air outlet housing 2. Vertical guide plates 4 are provided on both the left and right sides inside the air outlet housing 2. A front guide post 5 and a rear guide post 6 are respectively provided at the front and rear edges of the guide plate 4. Horizontal sliding grooves 7 extending in the left-right direction are provided at intervals up and down on the front side wall inside the air outlet housing 2. Longitudinal sliding grooves 8 extending in the front-rear direction are provided at intervals up and down on both the left and right side walls inside the air outlet housing 2. The upper and lower ends of the front guide post 5 slide in the horizontal sliding grooves 7, and the upper and lower ends of the rear guide post 6 slide in the longitudinal sliding grooves 8. A connecting component capable of sliding in the left-right direction is further provided inside the air outlet housing 2, and the front guide post 5 can be detachably connected to the connecting component.

[0030] According to the above structure, through the combined guidance of the horizontal sliding grooves 7 and the longitudinal sliding grooves 8, and in cooperation with the slidable connecting component, when centralized air supply is required, the front guide posts 5 on both sides can be driven to move closer along the horizontal sliding grooves 7, and the front guide posts 5 are connected and fixed to the connecting component, so as to change the inclination angles of the two groups of guide plates 4, and realize the adjustment of the air outlet area and the air output; of course, only the front guide post 5 of the guide plate on a single side can be connected to the connecting component, so that the air can be concentrated and blown out on one side; in addition, by the left-right sliding of the connecting component, the air outlet position can be adjusted, and further the device can be switched between multiple modes such as centralized air supply, single-side air supply, and wide-angle diffusion, so as to meet the purification requirements in different scenarios.

[0031] See Figure 3 、 Figure 7 As shown in the figure, a horizontally arranged partition plate 21 is provided inside the air outlet housing 2. The upper horizontal sliding groove 7 and the longitudinal sliding groove 8 are respectively arranged on the partition plate 21. Through the arrangement of the partition plate 21, the air outlet housing 2 can be divided into two cavities up and down. The lower cavity is used for ventilation, and the upper cavity is used for accommodating components such as the connecting component, and at the same time, the overall strength of the air outlet housing 2 can be enhanced.

[0032] See Figures 6-8 、 Figure 10As shown in the figure, a slide rail 31 extending in the left - right direction is provided at the upper end of the air outlet housing 2. A sliding seat 32 slides within the slide rail 31. The connection assembly includes a connection shaft 33 provided on the sliding seat 32. A connection disk 34 is provided at the lower end of the connection shaft 33. U - shaped card slots 35 are symmetrically arranged on the outer wall of the connection disk 34 with the connection shaft 33 as the center. Limiting flanges 36 are provided on both side walls of the U - shaped card slots 35. The front guide post 5 can slide along the transverse chute 7 and be snapped into the U - shaped card slots 35, and be limited and fixed by the limiting flanges 36.

[0033] When the front guide rod 5 is connected to the connection assembly, when the front guide rod 5 slides along the transverse chute 7 and is snapped into the U - shaped card slot 35 of the connection disk 34, and the front guide rod 5 can be limited and fixed by the limiting flange 36. When the sliding seat 32 slides within the slide rail 31, it can drive the connection shaft 33, the connection disk 34, and the front guide rod 5 to slide together. At the same time, the inclination angle of the guide plate 4 is adjusted, so as to adjust the air outlet area and the air outlet position.

[0034] It should be noted that when the front guide rod 5 slides within the transverse chute 7, its rear guide rod 6 slides and adjusts adaptively within the longitudinal chute 8, and at the same time, the rear guide rod 6 always remains against the inner wall surface of the air outlet housing 2.

[0035] Further, the connection disk 34 has a disk - shaped structure. A plurality of groups of U - shaped card slots 35 are arranged along the circumference, and the recessed depths of each group of U - shaped card slots 35 are different. The connection shaft 33 is rotatably arranged on the sliding seat 32, and a knob 41 is provided at the upper end of the connection shaft 33.

[0036] By rotating the connection disk 34, it can select U - shaped card slots 35 with different recessed depths to align with the front guide rod 5 and cooperate with the front guide rod 5. That is to say, when the front guide rods 5 on both sides are respectively snapped into U - shaped card slots 35 with different recessed depths, the distance between the two front guide rods 5 on the left and right (i.e., the distance D in the figure) can be adjusted, thereby adjusting the air outlet area to meet the usage requirements of different scenarios. Figure 6

[0037] Further, a support seat 51 is provided at the lower end of the sliding seat 32. Positioning grooves 52 corresponding to the number of U - shaped card slots 35 are evenly distributed along the circumference on the outer wall of the connection shaft 33. An elastic piece 53 is provided on the support seat 51. One end of the elastic piece 53 is fixedly provided on the support seat 51, and the other end is provided with a V - shaped positioning portion 54, and the V - shaped positioning portion 54 abuts against the positioning groove 52.

[0038]

[0038] After the connection plate 34 is rotationally adjusted, the V-shaped positioning portion 54 on the elastic piece 53 can cooperate with the positioning groove 52, having a positioning feedback function, and at the same time preventing the accidental rotation of the connecting shaft 33, ensuring the stability of the air deflector 4 after the angle adjustment.

[0039] See Figure 1 , Figure 2 , Figure 4 As shown in, baffles 60 are provided on both the left and right sides of the upper end of the sliding seat 32. The baffles 60 are arranged above the slide rail 31 and are used to block the slide rail 31. Thus, the baffles 60 cover the upper part of the slide rail 31, effectively preventing dust from entering the inside of the slide rail, avoiding the movement failure of the sliding seat 32 caused by foreign object jamming, and extending the service life of the slide rail.

[0040] To facilitate driving the front guide post 5 to slide in the transverse chute 7, a dial plate 61 is provided on the front guide post 5, and a first chute opening 62 extending in the left-right direction is provided on the front side of the air outlet housing 2. The dial plate 61 is slidably arranged on the first chute opening 62.

[0041] In the present invention, a transverse sliding device capable of driving the sliding seat 32 to automatically slide along the slide rail 31 is further provided in the air outlet housing 2.

[0042] Further, the transverse sliding device includes a motor 91 arranged on the air outlet housing 2. The output shaft of the motor 91 is arranged vertically downward and is connected with a transverse plate 92. A guide post 93 is arranged at the lower end of the transverse plate 92. Guide cross bars 94 extending in the left-right direction are spaced front and rear in the air outlet housing 2. A sliding cross beam 95 sliding in the left-right direction is connected between the two guide cross bars 94. The sliding cross beam 95 is fixedly connected with the support seat 51. A second chute opening 96 extending in the front-rear direction is provided on the sliding cross beam 95. The guide post 93 is arranged in the second chute opening 96.

[0043] To facilitate the protection of the motor 91 and improve the overall appearance of the device, the motor 91 is arranged at the upper end of the air outlet housing 2, and a protective housing 97 for protecting the motor 91 is arranged at the upper end of the air outlet housing 2.

[0044] The specific working principle of the transverse sliding device is as follows: When the motor 91 works, it drives the transverse plate 92 to rotate. Since the guide post 93 at the outer end of the transverse plate 92 is arranged in the second chute opening 96 on the sliding cross beam 95, it can thus move the sliding cross beam 95 to move in the left-right direction along the guide cross bar 95. The sliding cross beam 95 is fixedly connected with the support seat 51, and further drives the connecting shaft 33, the connection plate 34 and the sliding seat 32 to slide left and right, realizing the automatic adjustment of the air outlet position.
