[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] This invention provides a sweeping device, such as Figures 1-8 As shown, it includes: an air guide plate 1; a plurality of parallel and swinging sweeping blades 2, the sweeping blades 2 being movably connected to the air guide plate 1 and swinging relative to the surface of the air guide plate 1; a driving device that drives the sweeping blades 2 to swing relative to the surface of the air guide plate 1; and a wind baffle 3 provided between two adjacent sweeping blades 2, the wind baffle 3 including at least one air pressure plate 31, the air pressure plate 31 being disposed on one of the sweeping blades 2 and having a first gap in a first direction with the other sweeping blade 2, the first gap being used to ensure that the adjacent sweeping blades 2 do not interfere with each other when rotating.

[0037] When the sweeping blade 2 swings, the wind deflector 3, the air guide plate 1, and the two sweeping blades 2 adjacent to the wind deflector 3 always cooperate to form a flow channel.

[0038] The air guide plate 1 is existing technology and can swing up and down. The present invention focuses on the swingable air sweeping blades 2 arranged in parallel on the air guide plate 1, which achieve left and right air sweeping by swinging multiple air sweeping blades 2 left and right.

[0039] The driving device drives the oscillation of the air-sweeping blades 2 relative to the air guide plate 1. The driving device can be individually arranged corresponding to the plurality of air-sweeping blades 2, that is, there are N driving devices for N air-sweeping blades 2, so that each air-sweeping blade 2 is independent of each other. Of course, it is preferred that one driving device can simultaneously drive a plurality of air-sweeping blades 2 to sweep in one direction (left or right) to achieve the above-mentioned simultaneous left and right oscillation of a plurality of air-sweeping blades.

[0040] In order to reduce the gap between the air-sweeping blades 2 and the adjacent air-sweeping blades 2 and thus reduce the amount of transverse air leakage, a wind-blocking piece 3 is arranged on the side wall of the air-sweeping blade 2. The wind-blocking piece 3 can be a wind-blocking piece 31 or a plurality of wind-blocking pieces 31. The end of the wind-blocking piece 31 away from the air-sweeping blade 2 has a first gap with the adjacent air-sweeping blade 2. The first gap should meet the condition that the adjacent air-sweeping blade 2 does not interfere with the rotation, and the smaller the first gap, the better, so as to achieve the purpose of reducing the amount of transverse air leakage.

[0041] The first direction is parallel to the horizontal plane of the wind-blocking piece 3, which can be referred to as shown in Figure 8 .

[0042] As Figure 5 described, assuming that the rotation point of the air-sweeping blade 2 is arranged at O (the midpoint of the side wall of the air-sweeping blade 2), half the length of the air-sweeping blade 2 is d, the distance from the O point to the front side wall or the rear side wall of the air-sweeping blade 2 is A, and the length of the wind-blocking piece 31 is L, that is, the maximum rotation radius of the air-sweeping blade 2 and the wind-blocking piece 31 together is R1, wherein R1={(L+d) 2 +(A) 2} 1 / 2 , the maximum rotation radius of the corresponding air-sweeping blade 2 (without wind-blocking piece) is R2, wherein R2={(L) 2 +(A) 2} 1 / 2 , that is, when the wind-blocking piece 31 is arranged on one side wall of the air-sweeping blade 2 and the other side wall is not arranged with the wind-blocking piece 31, the gap is R1+R2={(L+d) 2 +(A) 2} 1 / 2 +{(L) 2 +(A) 2} 1 / 2 , that is, when the air-sweeping blade 2 is determined, the width b between the front side wall and the rear side wall of the air-sweeping blade 2 is arranged, and the value range of A is 1 / 2b~b. Thus, the adjacent air-sweeping blades 2 are not interfered with when they oscillate relative to the air guide plate 1.

[0043] The air guide channel is always formed by the cooperation between the wind-blocking piece 3, the air guide plate 1, and the two air-sweeping blades 2 adjacent to the wind-blocking piece 3.

[0044] Further optimization, the pressure wind piece 31 is arranged on two opposite side walls of the sweeping wind piece 2, and the two pressure wind pieces 31 between the adjacent two sweeping wind pieces 2 cooperate to form the wind blocking piece 3, and the two pressure wind pieces 31 constituting the wind blocking piece 3 have a second gap in the second direction, which ensures that the adjacent sweeping wind piece 2 does not interfere when rotating.

[0045] Correspondingly, as Figure 6 The pressure wind piece 31 is arranged on the two side walls (left side wall and right side wall) of the sweeping wind piece 2, that is, the second gap is R1+R1=2{(L+d) 2 +(A) 2} 1 / 2 The second direction is the direction perpendicular to the horizontal plane of the wind blocking piece 3. For reference Figure 8 .

[0046] Further optimization, the pressure wind piece 31 has a height difference with the pressure wind piece 31 on the adjacent sweeping wind piece 2.

[0047] The above-mentioned second gap exists in two-dimensional space, that is, the setting height between the pressure wind piece 31 and the pressure wind piece 31 on the adjacent sweeping wind piece 2 is consistent; when the wind blocking piece 3 and the pressure wind piece 31 on the adjacent sweeping wind piece 2 have a height difference, the second gap can exist in three-dimensional space.

[0048] Further optimization, the projection of the pressure wind piece 31 and the pressure wind piece 31 on the adjacent sweeping wind piece 2 in the second direction on the plane perpendicular to the second direction has a partial overlap.

[0049] By the height difference between the pressure wind piece 31 and the pressure wind piece 31 on the adjacent sweeping wind piece 2, the projection of the pressure wind piece 31 and the pressure wind piece 31 on the adjacent sweeping wind piece 2 in the second direction on the plane perpendicular to the second direction has a partial overlap, which can make the airflow to the wind blocking piece 3 flow in a winding manner (multiple pressure wind pieces 31 and multiple pressure wind pieces 31 are arranged in an interlaced manner), so that only less airflow flows out from the gap in unit time, which can further reduce the transverse air leakage.

[0050] Further optimization, the driving device comprises: a rotating shaft 4, the sweeping wind piece 2 is rotatably installed on the air deflector 1 through the rotating shaft 4; a driving member (not shown in the figure), driving the rotating shaft 4 to rotate; a power part (not shown in the figure), driving the driving member to move.

[0051] The plurality of sweeping blades 2 are arranged to rotate left and right through the respective rotating shafts 4 to achieve the purpose of left and right sweeping, the driving member can drive the rotating shafts 4 to rotate, preferably a gear can be used, and the power part can be driven by the meshing of the rack and pinion, and the corresponding driving source drives the rack. There are many ways to drive the reciprocating movement of the rack, and the output shaft of the common forward and reverse motor is provided with an output gear, the output gear meshes with the above-mentioned rack, and the forward and reverse rotation of the output gear can realize the forward and reverse rotation of the rotating shaft 4, thereby realizing the left and right sweeping of the sweeping blades 2, and in addition, reference can be made to Chinese patents with publication numbers CN114935170A and CN115978775A, and the like. The sweeping blades 2 are driven to swing left and right by the driving source, which is the prior art, and will not be described here.

[0052] Further optimization, the sweeping blade 2 comprises an upper plate 5 and a lower plate 6, and a plurality of vertical plates 7 are arranged between the upper plate 5 and the lower plate 6, and a pressure wind space is formed between the vertical plates 7.

[0053] The sweeping blade 2 is arranged to have a plurality of vertical plates 7 longitudinally arranged between the upper plate 5 and the lower plate 6, and a pressure wind space is formed between the plurality of vertical plates 7 to realize the pressure wind function of the sweeping blade 2. The plurality of vertical plates 7 can be evenly spaced to realize the pressure wind function of the sweeping blade 2. Compared with the prior art sweeping blade 2, the left and right sweeping of the air cylinder is avoided, which is used to solve the problems of air leakage between the sweeping blades 2 and the interference of the sweeping blades 2, and realizes synchronous pressure wind.

[0054] Further optimization, the rotating shaft 4 is arranged on the lower plate 6.

[0055] The rotating shaft 4 can be arranged on the lower plate 6 and the upper plate 5, and preferably, the lower plate 6 and the air deflector 1 are mutually attached, and the rotating shaft 4 is arranged on the lower plate 6.

[0056] Further optimization, the arrangement position of the rotating shaft 4 is close to the center position of the lower plate 6.

[0057] The arrangement position of the rotating shaft 4 determines the maximum rotating radius of the sweeping blade 2 and the maximum rotating radius of the corresponding pressure fin 31, and preferably the arrangement position of the rotating shaft 4 is close to the center position of the lower plate 6.

[0058] Further optimization, the closer the arrangement position of the rotating shaft 4 is to the center position of the lower plate 6, the greater the overlapping area of the projection of the pressure fin 31 and the adjacent pressure fin 31 on the vertical second direction along the second direction on the plane in the vertical second direction.

[0059] In order to further increase the overlapping area and thereby further reduce the amount of transverse air leakage, when the position of the rotating shaft 4 is arranged at the center position of the lower plate 6, the effect of reducing the transverse air leakage is most obvious.

[0060] To further verify the size of the overlapping area and the related parameters, such as Figure 7 As described above, assuming that the rotation point of the air-sweeping blade 2 is set at O (a point on the line connecting the center lines of the front and rear side walls of the air-sweeping blade 2), wherein the distance from the point O to the front or rear side wall of the air-sweeping blade 2 is A, and A is greater, since the air-pressing blades 31 are arranged in a staggered manner, it is only required that the air-pressing blades 31 do not interfere with the side walls of the adjacent air-sweeping blade 2 when the air-sweeping blade 2 rotates, i.e., the leftmost point of the maximum rotation range of the dashed line in the figure is the side wall of the air-sweeping blade 2. The area of the corresponding overlapping part is S=(L-(R-(L+d))*b=S=b*(2L+d-((L+d) 2 +(A) 2 ) 1 / 2 )) Therefore, when A=1 / 2b, the rotation point O is at the midpoint of the line connecting the center lines of the front and rear side walls, the area S is maximum, to ensure that the effect of reducing the amount of transverse air leakage is most obvious, and almost no transverse air leakage can be achieved. Furthermore, a plurality of air-pressing blades 31 and a plurality of air-pressing blades 31 can be alternately arranged in a staggered manner, so that the airflow can only flow in a meandering manner between the plurality of air-pressing blades 31, and only a smaller amount of airflow can flow out from the gap in a unit of time, which can further reduce the amount of transverse air leakage.

[0061] The application also provides an air conditioner, comprising: a shell 8; the air-sweeping device, wherein the air guide plate 1 in the air-sweeping device is rotationally connected to the air outlet of the shell 8, and the air guide plate 1 is flush with the surface of the shell 8 when closed.

[0062] Although the application is disclosed as above, the application is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the application, and the protection scope of the application should be subject to the scope defined by the claims.
