[0035] Further, an air guide assembly is movably arranged in the air outlet cover body 6 and directly below the branch air supply pipe 5, and the air guide assembly divides the air outlet cover body 6 into a left air outlet portion 8 and a right air outlet portion 9, and the air guide assembly includes an adjustable V-shaped air guide plate 10 and an adjusting device for adjusting the shape of the adjustable V-shaped air guide plate 10, and the adjustable V-shaped air guide plate 10 includes a middle hinge seat 11 and a left air guide plate 12 and a right air guide plate 13 hinged to the lower end of the middle hinge seat 11, and the adjusting device can adjust the adjustable V-shaped air guide plate 10 to a left-right ventilation form, a left ventilation form, and a right ventilation form;

[0040] See also Figure 7 , Fig. 9 As shown, a left abutting slope 21 is provided at the connecting corner between the branch air supply duct 5 and the left air outlet 8, and the middle hinged seat 11 can abut against the left abutting slope 21, so that the adjustable V-shaped air guide plate 10 is in a right ventilation form, and a right abutting slope 22 is provided at the connecting corner between the branch air supply duct 5 and the right air outlet 9, and the middle hinged seat 11 can abut against the right abutting slope 22, so that the adjustable V-shaped air guide plate 10 is in a left ventilation form.

[0041] See also Figure 4 , Figure 7 , Fig. 9 As shown, a left sliding seat 31 is hinged at the lower end of the left air guide plate 12, and a right sliding seat 32 is hinged at the lower end of the right air guide plate 13. A left sliding groove 33 and a right sliding groove 34 extending left and right are provided on the front and rear walls of the air outlet cover body 6. The left sliding seat 31 slides in the left sliding groove 33, and the right sliding seat 32 slides in the right sliding groove 34.

[0042] The shape of the adjustable V-shaped air guide plate 10 is adjusted by sliding the left sliding seat 31 along the left sliding groove 33, or sliding the right sliding seat 32 along the right sliding groove 34; for example, when the adjustable V-shaped air guide plate 10 needs left and right ventilation shapes, the left sliding seat 31 can slide to the leftmost side of the left sliding groove 33, and the right sliding seat 32 can slide to the rightmost side of the right sliding groove 34. At this time, the branch air supply pipe 5 is respectively connected to the left air outlet 8 and the right air outlet 9, and at the same time, the openings of the left air guide plate 12 and the right air guide plate 13 are opened larger.

[0043] In addition, the left sliding seat 31 can also slide to the middle position of the left sliding groove 33, and the right sliding seat 32 can slide to the middle position of the right sliding groove 34 (such as Fig.10 As shown), at this time, the branch air supply duct 5 is also connected to the left air outlet 8 and the right air outlet 9 respectively, but the openings of the left air guide plate 12 and the right air guide plate 13 are smaller, that is, the air outlet areas of the left air outlet 8 and the right air outlet 9 are increased.

[0044] Of course, the left and right ventilation forms are not limited to the two forms mentioned above. According to the on-site spraying requirements, the position of the left sliding seat 31 in the left slide groove 33 and the position of the right sliding seat 32 in the right slide groove 34 can be adjusted, so that the air outlet area of ​​the left air outlet 8 or the right air outlet 9 can be adjusted.

[0045] When the adjustable V-shaped air guide plate 10 needs to be in the right ventilation state, the left sliding seat 31 slides to the leftmost position of the left sliding groove 33, and the right sliding seat 32 slides to the leftmost position of the right sliding groove 34 (such as Fig. 9 As shown), at this time, the middle hinge seat 11 abuts against the left abutting inclined surface 21, so that the right air guide plate 13 closes the left air outlet 8 and guides the wind flow into the right air outlet 9 through the right air guide plate 13.

[0046] See also Figure 3-Figure 11 As shown, the adjusting device includes a motor 41, and a left transmission assembly 42 and a right transmission assembly 43 are respectively connected between the output shaft of the motor 41 and the left sliding seat 31 and the right sliding seat 32. The motor 41 can drive the left transmission assembly 42 alone to make the left sliding seat 31 slide back and forth along the left slide groove 33, or the motor 41 can drive the right transmission assembly 43 alone to make the right sliding seat 32 slide back and forth along the right slide groove 34.

[0047] Further, a motor mounting seat 51 is provided on the outer side of the air outlet cover 6, the motor 41 is provided on the motor mounting seat 51, a gear 52 is provided on the output shaft of the motor 41, the left transmission assembly 42 and the right transmission assembly 43 have the same structure, wherein both include a disc 53 rotatably provided on the outer side of the air outlet cover 6, a unidirectional elastic tooth assembly meshing with the gear 52 is uniformly distributed on the circumferential outer wall of the disc 53, the unidirectional elastic tooth assembly includes a groove 54 provided on the circumferential outer wall of the disc 53, A first spring 55 and a one-way tooth 56 are arranged in the groove 54. The one-way tooth 56 is meshed with the gear 52, and one side of the one-way tooth 56 is a slope structure 57, and the other side is a straight structure 58. An eccentric column 59 is arranged on the outer side of the disc 53. An extension seat 510 is extended outward on one side of the left sliding seat 31 and the right sliding seat 32. A vertical plate 511 extends upward on the extension seat 510. A vertical groove 512 is arranged on the vertical plate 511, and the eccentric column 59 is arranged in the vertical groove 512.

[0048] When the adjustable V-shaped air guide plate 10 is switched from the left and right ventilation mode to the right ventilation mode, the working principle is as follows (i.e., from Figure 7 Switch to Fig. 9 form):

[0049] The motor 41 drives the gear 52 to rotate counterclockwise. At this time, the teeth of the gear 52 move the straight-face structure 58 of the one-way tooth 56 on the right transmission assembly 43, thereby driving the corresponding disc 53 to rotate. The eccentric column 59 on the disc 53 cooperates with the vertical groove 512 on the vertical plate 511, and then drives the right sliding seat 32 to slide to the left along the right slide groove 34 through the vertical plate 511 and the extension seat 510. When the eccentric column 59 on the disc 53 rotates to the far left, the right sliding seat 32 slides to the far left of the right slide groove 34, and the middle hinged seat 11 abuts against the left abutting inclined surface 21, so that the right air guide plate 13 closes the left air outlet 8, and guides the wind flow into the right air outlet 9 through the right air guide plate 13.

[0050] It should be noted that when the gear 52 cooperates with the one-way tooth 56 on the right transmission component 43, the teeth of the gear 52 also cooperate with the one-way tooth 56 on the left transmission component 42, and the teeth of the gear 52 rest against the inclined surface structure 57 of the one-way tooth 56 on the left transmission component 42, so that the corresponding one-way tooth 56 retracts into the groove 54, the disc 53 on the left transmission component 42 remains stationary, and the left sliding seat 31 does not move.

[0051] Similarly, when the motor 41 drives the gear 52 to rotate clockwise, the right sliding seat 32 will not move, but the left sliding seat 31 can move, so that the single motor 41 and clever mechanical coordination can be used to achieve rapid adjustment of the shape of the adjustable V-shaped air guide plate 10, while further achieving the effect of energy saving and consumption reduction.

[0052] Furthermore, a first elastic positioning component for positioning the disc 53 is also provided on the air outlet cover body 6, and the first elastic positioning component includes a circular groove 61 provided on the outer wall of the air outlet cover body 6, and a second spring 62 and a positioning steel ball 63 are provided in the circular groove 61. A plurality of positioning grooves 64 are evenly distributed along the circumference of the inner wall of the disc 53, and the positioning steel ball 63 is pressed against the positioning groove 64 by the action of the second spring 62, and the positioning groove 64 is corresponding to the one-way elastic tooth component, and the number of the positioning grooves 64 is the same.

[0053] A second elastic positioning component for positioning the left sliding seat 31 and the right sliding seat 32 is also provided on the air outlet cover body 6, and the second elastic positioning component includes a wave groove 71 arranged on the edge of the lower wall of the air outlet cover body 6, and an arc-shaped spring piece 72 is arranged on the extension seat 510, and the arc-shaped spring piece 72 abuts against the wave groove 71.

[0054] That is to say, the stability of the disc 53 , the left sliding seat 31 and the right sliding seat 32 is improved by disposing the first elastic positioning assembly and the second elastic positioning assembly.

[0055] See also Figure 3 As shown, distance sensors 81 are provided at both ends of the air outlet cover 6, and the distance sensors 81 are used to measure the distance between the left sliding seat 31 / right sliding seat 32 and the two ends of the air outlet cover 6, so that the positions of the left sliding seat 31 and the right sliding seat 32 can be clearly understood in real time, and the air outlet areas of the air outlet part 8 and the right air outlet part 9 can be clearly understood.

[0056] See also Figure 2 As shown, a filter screen cover 91 is provided at the lower end of the air outlet cover body 6 .

[0057] In conjunction with the drawings and the above, the basic principles and main features of the present invention and the advantages of the present invention are shown and described. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
