Description

Technical Field

[0001] The utility model relates to the technical field of air duct structures, and in particular to a self-steering air duct structure and an air outlet device. Background Art

[0002] Household appliances such as humidifiers, aromatherapy machines, fans, and purifiers all have air outlet duct structure designs. In order to obtain a better experience, most of these appliances are designed with the function of changing the air outlet direction or air outlet angle when designing the air outlet duct. The existing air outlet duct change function is usually achieved by manual operation or adding an electric device. Among them, manual operation is troublesome, and the user's operating force will also affect the service life of the wind direction blade or the air outlet duct; the electric device needs to be powered by a power supply, which wastes energy and cost, and requires the air outlet duct and the main body to have a power transmission line. Under the current market demand for ultra-thin and minimalist, it is difficult to compress the structural space by adding an electric device. Therefore, self-reversing air duct structures have also appeared on the market. In this type of air duct structure, the angle of the wind direction blade is changed mainly by blocking the air inlet, blowing the wind direction blade directly through the air flow in the air inlet, and adjusting the wind speed. The rotating shaft of the wind direction blade needs to be arranged perpendicular to the air inlet direction, which cannot be used in many product structures. At the same time, this structure cannot work for structures where the air outlet part is the air outlet. Utility Model Content

[0003] The utility model discloses a self-steering air duct structure, which aims to improve the existing air duct structure, which has the problems of needing to add an electric device for self-steering, wasting energy and cost, being unable to compress the structural space, and utilizing the direct blowing method of wind flow, which limits the internal structure of the applicable air duct product, and the existing direct blowing method of the air duct is difficult to apply to the air outlet.

[0004] The utility model adopts the following scheme:

[0005] A self-steering air duct structure comprises a power wheel, a reversing member and a transmission assembly, wherein the power wheel is arranged in an air inlet channel, one end of the reversing member is used to connect with the transmission assembly, and the other end is used to connect with an air outlet or a wind direction blade, and the air duct structure is constructed to drive the power wheel to rotate through the airflow in the air inlet channel, so as to link the transmission assembly to drive the reversing member to move and / or rotate, so as to prompt the reversing member to drive the air outlet or the wind direction blade to rotate, thereby changing the air outlet direction or the air outlet angle; wherein the rotation center line of the air outlet or the wind direction blade is non-vertically arranged to the air inlet direction in the air inlet channel, so that the air duct structure can adapt to the internal space of the product.

[0006] As a further improvement, the rotation center line of the air outlet or the wind direction blade is parallel to the air inlet direction.

[0007] As a further improvement, the air outlet or the wind direction blade is configured to reciprocate within a set angle.

[0008] As a further improvement, one end of the reversing member is hinged to the transmission assembly so as to rotate with the transmission assembly, and the other end is hinged to the first rotating shaft. The other end of the first rotating shaft relative to the reversing member is used to connect with the air outlet or wind direction blade.

[0009] As a further improvement, the transmission assembly includes a first gear coaxially configured with the power wheel, and a second gear meshing with the first gear, the second gear being provided with a second rotating shaft for connecting the reversing member, wherein the diameter of the second gear is greater than the diameter of the first gear.

[0010] As a further improvement, one end of the switching member is hinged to the second rotating shaft, and the other end is hinged to the first rotating shaft. The air outlet or wind direction blade is provided with a driving part and a rotating hole is arranged along the rotation center. The rotating hole is sleeved on the fixed column of the air duct, and the mounting hole on the driving part is sleeved on the first rotating shaft. When one end of the switching member rotates with the second rotating shaft, the first rotating shaft is restricted by the switching member and the rotating hole, thereby driving the driving part to rotate with a radius of the distance from the axis of the rotating hole to the axis of the mounting hole.

[0011] As a further improvement, the driving part is configured to extend outward from the rotation center of the wind direction blade, or to extend inward from the air inlet end of the air outlet.

[0012] As a further improvement, the switching member is arranged in a "7" shape.

[0013] As a further improvement, the power wheel is a pneumatic wheel.

[0014] A wind outlet device is also provided, comprising a main body and an air duct structure arranged on the main body, wherein the air duct structure is the self-steering air duct structure as described above.

[0015] By adopting the above technical solution, the utility model can achieve the following technical effects:

[0016] The present application collects the airflow in the air inlet channel through a power wheel to form a rotational power, thereby driving the transmission member to drive the reversing member to move and / or rotate, thereby causing the air outlet or wind direction blade whose rotation center line is not arranged perpendicular to the air inlet direction to change the air outlet direction or air outlet angle. Automatic adjustment of the air outlet angle without power is achieved, saving costs and energy consumption. At the same time, the rotation center line of the air outlet and the wind direction blade can be arranged non-perpendicularly to the air inlet direction, which can adapt to the structure or appearance of more products. It solves the problem that the existing air duct structure needs to add an electric device for self-steering, which wastes energy and cost and cannot compress the structural space, and the direct blowing method of the wind flow limits the internal structure of the applied air duct product, and the direct blowing method of the air duct is difficult to apply to the air outlet.

[0035] Example

[0036] Combination Figures 1 to 8 The present embodiment provides a self-steering air duct structure, including a power wheel 1, a reversing member 2 and a transmission assembly. The power wheel 1 (preferably a pneumatic wheel) is arranged in the air inlet channel 4. One end of the reversing member 2 is used to connect with the transmission assembly, and the other end is used to connect with the air outlet 5 or the wind direction blade 6. The air duct structure is constructed to drive the power wheel 1 to rotate through the airflow in the air inlet channel 4, so as to drive the reversing member 2 to move and / or rotate through the linkage transmission assembly, so as to prompt the reversing member 2 to drive the air outlet 5 or the wind direction blade 6 to rotate, thereby changing the air outlet direction or the air outlet angle; wherein, the rotation center line of the air outlet 5 or the wind direction blade 6 is non-vertically arranged with the air inlet direction in the air inlet channel 4, so that the air duct structure can adapt to the internal space of the product.

[0037] It should be mentioned that, in the present embodiment, the airflow in the air inlet channel 4 is collected by the power wheel 1 to form a rotational power, thereby driving the transmission member to drive the reversing member 2 to move and / or rotate, thereby causing the air outlet 5 or the wind direction blade 6 whose rotation center line is not arranged perpendicular to the air inlet direction to change the air outlet direction or the air outlet angle. The air outlet angle can be automatically adjusted without power, saving costs and energy consumption. At the same time, the rotation center line of the air outlet and the wind direction blade can be arranged non-perpendicularly to the air inlet direction, which can adapt to the structure or appearance of more products. It solves the problems that the existing air duct structure needs to add an electric device for self-steering, which wastes energy and cost, cannot compress the structural space, and uses the direct blowing method of wind flow, which limits the internal structure of the air duct product to which it is applied, and the direct blowing method of the air duct is difficult to apply to the air outlet 5.

[0038] In a preferred embodiment, the rotation centerline of the air outlet 5 or the wind direction blade 6 is arranged parallel to the air inlet direction, and can also be arranged at an angle of 30°, 60°, etc., without specific limitation. One end of the reversing member 2 is hinged to the transmission assembly to rotate with the transmission assembly, and the other end is hinged to the first rotating shaft 7. The other end of the first rotating shaft 7 relative to the reversing member 2 is used to connect with the air outlet 5 or the wind direction blade 6. The transmission assembly includes a first gear 31 coaxially arranged with the power wheel 1, and a second gear 32 meshing with the first gear 31. The second gear 32 is provided with a second rotating shaft 321 for connecting the reversing member 2, wherein the diameter of the second gear 32 is larger than the diameter of the first gear 31. The deceleration function is realized by the transmission setting of the second gear 32 and the first gear 31, so as to avoid the power wheel 1 from rotating too fast and ensure the smooth change of the air outlet 5 or the wind direction blade 6.

[0039] Exemplarily, one end of the reversing member 2 is hinged to the second rotating shaft 321, and the other end is hinged to the first rotating shaft 7. The air outlet 5 or the wind direction blade 6 is provided with a driving part 61 and a rotating hole 62 is provided along the rotation center. The rotating hole 62 is sleeved on the fixed column 41 of the air duct, and the mounting hole 611 on the driving part 61 is sleeved on the first rotating shaft 7. When one end of the reversing member 2 rotates with the second rotating shaft 321, the first rotating shaft 7 is restricted by the reversing member 2 and the rotating hole 62, and the driving part 61 is moved to rotate with the distance from the axis of the rotating hole 62 to the axis of the mounting hole 611 as the radius. By setting the length of the reversing member 2 and the distance between the mounting hole 611 and the rotating hole 62, or by setting a radial limiting structure between the rotating hole 62 and the fixed column 41, the air outlet 5 or the wind direction blade 6 is set to reciprocate within a set angle, or to rotate 360°. It can be designed according to product requirements. Preferably, the reversing member 2 is arranged in a "7" shape to save the moving space of the reversing member 2. Preferably, the first rotating shaft 7 and the second rotating shaft 321 are both sleeved with bearings 8 to ensure smooth rotation of the rotating shafts.

[0040] In one embodiment, the driving part 61 is configured to extend outward from the rotation center of the wind direction blade 6 to realize the rotation of the wind direction blade 6. In another embodiment, the air inlet end of the air outlet 5 is sleeved on the outer periphery of the air inlet channel 4, and the driving part is extended inward along the inner wall of the air inlet end of the air outlet 5. When the driving part is turned, the air outlet end of the air outlet 5 rotates around the air inlet end.

[0041] The utility model further provides an air outlet device, comprising a main body and an air duct structure arranged on the main body, wherein the air duct structure is a self-steering air duct structure as described in any of the above embodiments. For example, a blower mechanism is arranged on the main body, and the air outlet end of the blower mechanism is connected to the air inlet channel 4 of the air duct structure, so that the change of the air outlet angle or direction is achieved through the air duct structure, wherein the main body can be a humidifier, an aromatherapy machine, a fan, a purifier, an air conditioner, etc. without specific limitation.

[0042] The above are only preferred implementations of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All technical solutions under the concept of the present utility model belong to the protection scope of the present utility model.
