DETAILED DESCRIPTION

[0031] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0032] The present invention relates to an air guide structure, comprising a first motor 100, a drive shaft 200, a first air guide blade group 300 and a second air guide blade group 400.

[0033] like Figure 1 As shown, the first motor 100 is connected to the drive shaft 200. The first motor 100 can be a unidirectional rotating motor or a bidirectional rotating motor. The first motor 100 and the drive shaft 200 can be directly connected, or indirectly connected through intermediate components such as couplings and reducers. The first motor 100 drives the drive shaft 200 to rotate, which can be to drive the drive shaft 200 to rotate in one direction or in two directions. The first guide blade group 300 and the second guide blade group 400 are installed on the drive shaft 200. The first guide blade group 300 and the second guide blade group 400 can be connected to the drive shaft 200 by plugging, welding, integral injection molding, etc. The first guide blade group 300 and the second guide blade group 400 are both tilted on the drive shaft 200, and the tilt directions of the first guide blade group 300 and the second guide blade group 400 are opposite. The air guide structure is mainly used in the air outlet device, which can be a bathroom heater, air conditioner, drying mechanism, etc. As Figure 5As shown, the air outlet device also includes a shell 500 and a fan 600. The fan 600 is installed on the shell 500, and the shell 500 is provided with an air supply port 510. The fan 600 delivers airflow in the direction of the air supply port 510. An independent air duct can be set between the fan 600 and the air supply port 510 to guide the air. The air guide structure is installed at the air supply port 510. The drive shaft 200 of the air guide structure is arranged horizontally relative to the air supply port 510. The airflow delivered by the fan 600 is roughly perpendicular to the drive shaft 200 and blows toward the air supply port 510. Part of the airflow flows through the first guide blade group 300, and part of the airflow flows through the second guide blade group 400. The first motor 100 is started, driving the drive shaft 200 to rotate around its own central axis. The first guide blade group 300 generates a first force component F1 on the airflow passing through it. The first force component compresses the airflow along the axial direction of the drive shaft 200, and in conjunction with the original flow direction of the airflow, causes the airflow flowing through the first guide blade group 300 to swing laterally. The second guide blade group 400 generates a second force component F2 on the airflow passing through it. The second force component compresses the airflow along the axial direction of the drive shaft 200, and in conjunction with the original flow direction of the airflow, causes the airflow flowing through the second guide blade group 400 to swing laterally. Moreover, since the first guide blade group 300 and the second guide blade group 400 are tilted in opposite directions, the first force component and the second force component generated on the airflow are in opposite directions along the drive shaft 200. Figure 1 As shown, when the first motor 100 rotates forward, the first guide blade group 300 and the second guide blade group 400 are distributed left and right on the drive shaft 200 in the direction shown in the figure. The first component force generated by the first guide blade group 300 on the airflow is axially to the right along the drive shaft 200, so that the airflow flowing through the first guide blade group 300 blows out the air supply port 510 and then swings forward to the right. The second component force generated by the second guide blade group 400 on the airflow is axially to the left along the drive shaft 200, so that the airflow flowing through the second guide blade group 400 blows out the air supply port 510 and then swings forward to the left. The two airflows converge in the center, thereby achieving a wind gathering effect, which is beneficial to increasing the wind speed and air supply distance, and reducing the temperature difference in the vertical direction. As shown Figure 2As shown, when the first motor 100 reverses, the first guide blade group 300 and the second guide blade group 400 are distributed left and right on the drive shaft 200 in the direction shown. The first guide blade group 300 generates a first component of force on the airflow that is directed to the left along the axis of the drive shaft 200, causing the airflow flowing through the first guide blade group 300 to swing forward and to the left after being blown out of the air outlet 510. The second component of force on the airflow generated by the second guide blade group 400 is directed to the right along the axis of the drive shaft 200, causing the airflow flowing through the second guide blade group 400 to swing forward and to the right after being blown out of the air outlet 510. The two airflows are relatively far apart, thereby achieving an air expansion effect, which is beneficial for expanding the air outlet area and improving the problem of uneven spatial temperature caused by a small lateral air outlet angle. In addition, as the speed of the first fan 600 increases, the first and second components of force generated will also increase accordingly. Depending on the direction of the first fan 600, the faster the speed, the more obvious the corresponding wind gathering effect or air expansion effect. The overall structure of the air guide structure is simple, and the wind gathering or expanding effect can be achieved by rotating the drive shaft 200 in coordination with the first air guide blade group 300 and the second air guide blade group 400.

[0034] Among them, in order to improve the wind gathering and expansion effects, such as Figure 3 As shown, the first guide blade group 300 and the second guide blade group 400 are mirror-symmetrical on the drive shaft 200 relative to a plane 800 perpendicular to the drive shaft 200. Alternatively, the plane may be located at the axial center of the drive shaft 200 and perpendicular to the drive shaft 200, and the first guide blade group 300 and the second guide blade group 400 are mirror-symmetrical about the plane. When the drive shaft 200 rotates, the first guide blade group 300 and the second guide blade group 400 rotate at opposite speeds, and the generated first and second force components are equal in magnitude and opposite in direction. The two airflows can converge in a relatively balanced manner to achieve maximum wind gathering, or the two airflows can separate to achieve consistent swing angles to the left and right.

[0035] In one embodiment, Figure 1 and Figure 2 As shown, the first guide blade group 300 and the second guide blade group 400 are both in a spiral sheet structure. The first guide blade group 300 and the second guide blade group 400 are both arranged around the drive shaft 200 along the axial direction of the drive shaft 200. The first guide blade group 300 and the second guide blade group 400 can be composed of multiple spiral sheets, or can be composed of a continuous spiral extending spiral sheet. The rotation directions of the first guide blade group 300 and the second guide blade group 400 are opposite. When the first guide blade group 300 and the second guide blade group 400 rotate one circle with the drive shaft 200, the airflow flowing through the first guide blade group 300 and the second guide blade group 400 swings horizontally for one cycle. The first motor 100 rotates forward through one of the spiral surfaces of the spiral sheet to generate thrust on the airflow, and the first motor 100 rotates counterclockwise through the other spiral surface of the spiral sheet to generate thrust in the opposite direction on the airflow.

[0036] In one embodiment, Figure 3 As shown, the first guide blade group 300 includes a plurality of first blades 310, and the second guide blade group 400 includes a plurality of second blades 410. The first blades 310 and the second blades 410 are both flat-plate-shaped. Each first blade 310 is sequentially distributed along the axial direction of the drive shaft 200, and the first blades 310 are arranged obliquely to the drive shaft 200. When the first blades 310 rotate with the drive shaft 200, the first blades 310 form the above-mentioned first component force on the airflow passing through. Each second blade 410 is sequentially distributed along the axial direction of the drive shaft 200, and the second blades 410 are arranged obliquely to the drive shaft 200. When the second blades 410 rotate with the drive shaft 200, they form the above-mentioned second component force on the airflow passing through. Specifically, the space where the air guide structure is located has a spatial rectangular coordinate system O-xyz. The axial direction of the drive shaft 200 is parallel to the y-axis. When the drive shaft 200 rotates to one of the positions, the first blade 310 and the second blade 410 are both perpendicular to the xOy plane, and the first blade 310 is inclined to the yOz plane and the xOz plane, while the second blade 410 is inclined to the yOz plane and the xOz plane. This determines the installation orientation of the first blade 310 and the second blade 410 on the drive shaft 200.

[0037] In one embodiment, Figure 1 As shown, the drive shaft 200 includes a first shaft section 210 and a second shaft section 220. The first shaft section 210 and the second shaft section 220 are coaxially connected. Figure 3 As shown, the first shaft section 210 and the second shaft section 220 can be integrally formed, or can be connected by clamping the ends together or by couplings. The first guide vane group 300 is provided on the first shaft section 210, and the second guide vane group 400 is provided on the second shaft section 220. Figure 1 、 Figure 2 and Figure 3 As shown, the first shaft segment 210 and the second shaft segment 220 are both solid or hollow rod structures. Figure 4 As shown, the first shaft segment 210 and the second shaft segment 220 are both hollow frame structures.

[0038] Based on the above embodiments, Figure 5 As shown, the air outlet device also includes a second motor and a fan blade 700. The fan blade 700 is swingably mounted at the air outlet 510. The fan blade 700 swings longitudinally relative to the air outlet 510. The axial direction of the drive shaft 200 is arranged horizontally relative to the air outlet 510. It is explained here that the above-mentioned horizontal and longitudinal directions are perpendicular to each other, the horizontal direction is the horizontal direction, and the longitudinal direction is the vertical direction. In the direction shown in the figure, the airflow swings horizontally left and right under the wind-guiding action of the wind-guiding structure, and the airflow swings longitudinally up and down under the wind-guiding action of the fan blade 700, thereby increasing the air supply range of the airflow in the longitudinal direction.

[0039] Based on the above embodiment, the air outlet device further includes a control mechanism. The air outlet device also includes a human body sensor and / or a temperature sensor. The human body sensor can be an infrared sensor, microwave radar, or the like. The human body sensor is mounted on the housing 500 and is used to detect the user's position in the environment. The temperature sensor can be mounted on the housing 500, or multiple temperature sensors can be arranged at different spatial locations in the environment to detect the temperature at different locations in the environment. The human body sensor, the temperature sensor, the first motor 100, and the second motor are electrically connected to the control mechanism. When a human body sensor is provided, the human body sensor detects the position of a human body in the environment to generate a first signal, which is fed back to the control mechanism. The control mechanism, using a pre-set control program within it, controls the speed and / or direction of the first motor 100 and the second motor, thereby controlling the lateral and longitudinal swing speeds and / or angles, focusing the airflow to maximize its impact on the human body, or diversifying the airflow to minimize its impact on the human body. When a temperature sensor is provided, the temperature sensor detects the temperature at multiple locations in the environment to generate a second signal, which is fed back to the control mechanism. The control mechanism controls the rotation speed and / or direction of the first motor 100 and the second motor, thereby delivering air to locations with lower or higher spatial temperatures, thereby achieving an all-round constant temperature effect in the environment.
