The embodiment of the application provides an air volume control assembly 10 for an air duct. As shown in fig. 1 to 3, the air volume control assembly 10 includes:
a barrel 110, the barrel 110 defining an air outlet 110a;
a first baffle 120, wherein the first baffle 120 is connected to the cylinder 110, and the first baffle 120 has a first vent 120a communicable with the air duct 110a;
a second baffle 130, wherein the second baffle 130 has a second vent hole 130a, and the second baffle 130 is tightly attached to the first baffle 120; and
a driving structure 140, wherein the driving structure 140 is connected with the cylinder 110; the driving structure 140 is connected to the second baffle 130, and is configured to drive the second baffle 130 to move; the second barrier 130 has at least a first position and a second position, and the second barrier 130 blocks a portion of the first ventilation hole 120a; when the second baffle 130 is at the first position, the cross-sectional flow area of the first vent hole 120a is a first flow area; when the second baffle 130 is at the second position, the cross-sectional flow area of the first vent hole 120a is a second flow area; wherein the first flow area is larger than the second flow area.
In the technical solution provided in the embodiment of the present application, the air volume control assembly 10 includes a cylinder 110, a first baffle 120, a second baffle 130, and a driving structure 140. The cylinder 110 defines an air outlet 110a for air flow. The first baffle 120 is connected to the cylinder 110, and the first baffle 120 has a first vent hole 120a communicable with the air duct 110a such that air can flow into the air duct 110a through the first vent hole 120a. The second baffle 130 is closely attached to the first baffle 120 and has a second ventilation hole 130a. The driving structure 140 is connected to the barrel 110, and is connected to the second barrier 130, and is used for driving the second barrier 130 to move; and the second baffle 130 has at least a first position and a second position; as shown in fig. 2, when the second baffle 130 is at the first position, the second baffle 130 blocks a portion of the first vent 120a, and air can enter the air duct 110a through the portion of the first vent 120a and a portion of the second vent 130a, where a cross-sectional area of the first vent 120a is a first flow area; as shown in fig. 3, when the second baffle 130 is at the second position, the second baffle 130 blocks a portion of the first vent 120a, and air can enter the air duct 110a through the portion of the first vent 120a and a portion of the second vent 130a, where a cross-sectional area of the first vent 120a is a second flow area; wherein the first flow area is larger than the second flow area. That is, when the second baffle 130 is located at a different position, the flow area of the first vent 120a blocked by the second baffle 130 is different, and the air volume entering the air duct 110a is different, so that the air volume control assembly 10 according to the embodiment of the present application can control the air volume entering the air duct machine.
It is easily understood that the opening area of the first ventilation hole is fixed. When the second baffle 130 moves from the first position to the second position, the area of the opening of the first ventilation hole, which is blocked by the second baffle 130, gradually increases, the range of the second ventilation hole falling into the first ventilation hole gradually decreases from the projection, and the air volume gradually decreases. In the process that second baffle 130 moves from the second position to the first position, the drill way area that second baffle 130 sheltered from first ventilation hole diminishes gradually, and from the projection, the scope that the second ventilation hole falls into first ventilation hole grow gradually, and the amount of wind increases gradually.
It should be noted that the driving structure 140 includes an output shaft 140a, the output shaft 140a is connected to the connecting shaft 130b of the second baffle 130, and the driving structure 140 outputs power to the connecting shaft 130b through the output shaft 140a to drive the second baffle 130 to move, so that the second baffle 130 can be located at the first position or the second position, and can move between the first position and the second position to change the air volume. Typically, the drive structure 140 is a motor. The housing 20 of the motor is fixed to the cylinder 110, for example, by welding, screwing, clipping, or riveting. The connecting shaft 130b of the second blocking plate 130 and the output shaft 140a may be splined or welded.
It should be noted that the cylinder 110 is generally formed to extend axially. The first baffle 120 is fixedly connected to the cylinder 110 and generally located in the air duct 110a; in some cases, the first baffle 120 may also be located outside the air duct 110a and at the air outlet, and fixed to the barrel 110 by screwing, welding, or the like.
In addition, the number of the first vent holes may be plural, for example, when the second baffle plate 130 is at the first position, the flow cross-sectional area of the first vent hole 120a is set to be
Wherein n is the number of the first vent holes, S1 i Is the cross-sectional flow area of the ith first vent when the second flap 130 is in the first position. Similarly, when the second baffle 130 is at the second position, the cross-sectional area of the first ventilation hole 120a is set as
Wherein n is the number of the first vent holes, S2 i For the ith first vent hole in the secondThe cross-sectional flow area when the baffle 130 is in the second position.
As an alternative to the above embodiment, as shown in fig. 4 and 5, the second baffle 130 further has a start position and an end position; the first position and the second position are both between the starting position and the ending position. Namely: the driving structure 140 drives the second shutter 130 to move from the start position to the end position, or from the end position to the start position. During the movement of the driving structure 140 driving the second barrier 130, the second barrier 130 passes through the first position and the second position. When the second shutter 130 is at the end position, the first vent hole 120a is not shielded by the second shutter 130; as shown in fig. 4, when the second blocking plate 130 is at the initial position, the second blocking plate 130 completely blocks the first vent hole 120a. As shown in fig. 5, when the second baffle 130 is located at the end position, the first vent hole 120a is disposed opposite to the second vent hole 130a, and at this time, the cross-sectional area of the first vent hole 120a is the opening area of the first vent hole 120a, so that the air volume can reach the maximum value. When the second baffle 130 is located at the initial position, the first vent hole 120a is completely blocked by the second baffle 130, and the flow path between the second vent hole 130a and the air duct 110a is blocked by the second baffle 130, and the flow cross-sectional area of the first vent hole 120a is 0.
As an alternative to the above embodiment, the second blocking plate 130 has a connecting shaft 130b, and the driving structure 140 is configured to drive the second blocking plate 130 to rotate around the connecting shaft 130 b. When the second shutter 130 rotates, the rotation of the second vent holes 130a forms a trajectory, i.e., a rotation path. The first ventilation holes 120a of the first baffle 120 are disposed corresponding to the rotation path. For example, the distance of the first ventilation hole 120a from the axis of the connection shaft 130b is equal to the distance of the second ventilation hole 130a from the axis of the connection shaft 130 b. During the rotation of the second baffle 130, the second vent hole 130a rotates to pass through the position corresponding to the first vent hole 120a, so as to change the cross-sectional area of the first vent hole 120a, and further change the air volume.
As an alternative to the above-described embodiment, in order to widen the range of adjustment of the air volume, the present embodiment sets the maximum value of the air volume by increasing the total opening area of the first vent hole 120a by providing a plurality of first vent holes 120a and second vent holes 130a. Specifically, the second baffle 130 has a plurality of second ventilation holes 130a located on the same circumference and arranged at intervals. Namely: a plurality of second vent holes 130a are arranged at intervals on a circumference of the second baffle 130, and the first baffle 120 is correspondingly provided with first vent holes 120a on the rotation path of the second vent holes 130a, and the rotation path defined by the second vent holes 130a on the same circumference is positioned on the circumference. Each of the circumferentially spaced second vent holes 130a corresponds to the first vent hole 120a. And/or the second baffle 130 has a plurality of second ventilation holes 130a arranged at radial intervals; that is, the radially spaced second vent holes 130a define different rotational paths, but the rotational paths are circular arcs and are concentric; the first baffle 120 is provided with corresponding first ventilation holes 120a on the rotation paths of different circumferences, and the first ventilation holes 120a are communicated with the second ventilation holes 130a on the corresponding rotation paths.
It is easily understood that the structure of the first array of baffles 120 provided with the first ventilation holes 120a is identical to the structure of the second array of baffles 130 provided with the second ventilation holes 130a.
As an alternative to the above embodiment, as shown in fig. 7, each of the second vent holes 130a has a first hole wall 130a-1 and a second hole wall 130a-2 spaced apart in the radial direction, the first hole wall 130a-1 and the second hole wall 130a-2 have the same curvature, and the curvature centers of the first hole wall 130a-1 and the second hole wall 130a-2 are located at the centroid of the second baffle 130. Namely: first bore wall 130a-1 and second bore wall 130a-2 are located on different circumferences when viewed in plan. When the second baffle 130 rotates, the first hole wall 130a-1 is a part of the motion track of the first hole wall 130a-1, and the second hole wall 130a-2 is a part of the motion track of the second hole wall. In a specific implementation, each second ventilation hole 130a is identical to the first ventilation hole 120a on the corresponding rotation path in shape and size. According to the arrangement, the second vent hole 130a is always positioned in the area limited by the movement thereof, so that the corresponding relation between the air volume and the rotation angle is provided, and the control of the air volume is facilitated.
The radian of the first hole wall 130a-1 and the second hole wall 130a-2 is 120 degrees and the opening area of the second vent hole 130a is a, which are analyzed by a single second vent hole 130a. As shown in fig. 2 to 5, for example, at the initial position, the rotation angle is 0, and the conductive area of the first vent hole 120a is 0; in the second position, the rotation angle β is 40 °, then the accessible area of the first ventilation hole 120a is 1/3A; in the first position, the rotation angle β is 80 °, so the accessible area of the first ventilation hole 120a is 2/3A at this time; in the terminal position, the rotation angle β is 80 °, and the accessible area of the first ventilation hole 120a is a at this time. It can be seen that, if the radian of the first hole wall 130a-1 and the second hole wall 130a-2 is α and the rotation angle is β (β ≦ α), then: the conductive cross-sectional area of the first vent hole 120a is β/α · S1 i 。
Further, as an alternative to the above embodiment, the first hole walls 130a-1 located on the same circumference have the same arc length, and the second hole walls 130a-2 located on the same circumference have the same arc length. That is, the sizes of the first ventilation holes 120a located on the same circumferential direction are uniform; further, the conductive sectional areas of the first vent holes 120a on the same circumference may be linearly overlapped. For example, if the radians of the first hole wall 130a-1 and the second hole wall 130a-2 are α, the rotation angle is β (β ≦ α), and the number of the second vent holes 130a located on the same circumference is n, then: the conductive cross-sectional area of the first vent hole 120a is n β/α · a.
Further, it is to be noted that if it is necessary to set the minimum value of the air volume to 0, the second baffle 130 has a start position to completely shield the first ventilation holes 120a, and at this time, the second ventilation holes 130a located on the same circumference need to satisfy: the radian of the interval between two circumferentially adjacent second vent holes 130a is greater than or equal to a, that is, 2n a is less than or equal to 360 °.
As an alternative to the above embodiment, referring to fig. 2 to 5, the first hole wall 130a-1 of each of the second ventilation holes 130a has the same curvature, and the second hole wall 130a-2 of each of the second ventilation holes 130a has the same curvature. Namely: in the same radial direction, the radians of the second vent holes 130a are the same and equal to the radians of the first hole wall 130a-1 and the second hole wall 130 a-2. Analysis of forming the second group of the vent holes 130a with the second vent holes 130a in the same radial direction, assuming that the opening area of the second group of the vent holes 130a is B (equal to the sum of a spacing of the second vent holes 130a in the same radial direction), then: for example, at the initial position, the rotation angle is 0, and the conductive area of the corresponding first ventilation hole 120a group is 0; in the second position, the rotation angle is 40 °, and then the accessible area of the corresponding first ventilation hole 120a group is 1/3B; in the first position, the rotation angle is 80 °, and then the accessible area of the corresponding first ventilation hole 120a group is 2/3B; in the end position, the rotation angle is 80 °, and at this time, the achievable area of the corresponding group of the first ventilation holes 120a is B. It can be seen that if the radian of each second vent hole 130a is α and the rotation angle is β (β ≦ α), then: the conductive cross-sectional area of the first vent hole 120a group is β/α · B. According to the arrangement, the air volume and the rotation angle have one-to-one correspondence, and the control of the air volume is facilitated.
As an optional implementation manner of the above embodiment, the cylinder 110 is provided with an air inlet, and the air inlet is communicated with the air duct 110a; the first baffle 120 is fixed in the air duct 110a, and covers the air inlet; the second baffle 130 is tightly attached to a side of the first baffle 120 away from the air inlet. The first baffle 120 can be engaged, welded, screwed into the air duct 110a, and covers the air inlet. After at least a portion of the second ventilation holes 130a is communicated with the first ventilation holes 120a, air may enter the air duct 110a through the air inlet, the first ventilation holes 120a, and the second ventilation holes 130a. The second baffle 130 is closely attached to a side of the first baffle 120 away from the air inlet, so that only after at least a portion of the second vent holes 130a is communicated with the first vent holes 120a, the air can enter the air duct 110 a.
As an optional implementation manner of the above embodiment, as shown in fig. 1 and fig. 6, the cylinder 110 is provided with an air outlet, the air outlet is communicated with the air duct 110a, and the air outlet and the air inlet are located at two opposite ends of the cylinder 110.

The air volume control assembly 10 further includes a fixing frame, which is connected to one end of the cylinder 110, where the air outlet is disposed, and is used for supporting the driving structure 140. The fixing frame is arranged at one end of the air outlet and used for supporting the driving structure 140, and installation of the driving structure 140 is facilitated. For example, the fixing structure 150 includes a first branch and a second branch, the first branch and the second branch are disposed in a crossing manner and connected to each other, and form a limiting portion, and the limiting portion is used for connecting the driving structure 140.
