Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to an angle-adjustable oscillating assembly and an electric fan using the same. Background Technology

[0002] Fans are common household appliances, and people often use them to cool down when the weather is hot.

[0003] Currently, there are two types of floor fans on the market: those that can oscillate and those that cannot. The oscillation angle of oscillating fans is around 120°, but the oscillation angle is too large and cannot be adjusted. For a single user, there is a long gap in the time when they cannot feel the wind and do not feel cool. This cannot meet the needs of using a fan to blow air in hot weather. Utility Model Content

[0004] To address the aforementioned shortcomings, the purpose of this utility model is to propose an adjustable oscillation assembly and an electric fan using it, thereby solving the problems of existing electric fans having excessively large oscillation angles that cannot be adjusted, resulting in a long gap between user periods where no airflow is available, no cooling sensation, and failure to meet the user's needs for airflow in hot weather.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An angle-adjustable oscillation assembly includes a fixed base, a left and right oscillation assembly, a connecting assembly, an angle detection assembly, and a controller;

[0007] The connecting assembly is rotatably mounted on the top of the fixed base, the left and right swaying assembly and the angle detection assembly are disposed on the connecting assembly, and the controller is electrically connected to the left and right swaying assembly and the angle detection assembly through wires;

[0008] The left and right swaying assembly is used to drive the connecting assembly to rotate left and right relative to the fixed base. The angle detection assembly is used to detect the rotation angle of the connecting assembly. The controller is used to control the left and right swaying assembly to work according to the rotation angle detected by the angle detection assembly.

[0009] Preferably, the connecting assembly includes a support and a rotating shaft, the rotating shaft being coaxially rotatably mounted on the top end of the fixed base, and the support being coaxially fixedly mounted on the top end of the rotating shaft.

[0010] Preferably, the left and right swaying assembly includes a drive motor, which is fixedly mounted on the support. The output shaft of the drive motor is coaxially connected to a gear, and one side of the gear is meshed with an arc-shaped rack, which is fixedly mounted on the fixed base.

[0011] Preferably, the arc-shaped rack is coaxially arranged with the rotating shaft.

[0012] Preferably, the angle detection component includes a magnet, and the upper surface of the support is provided with an arc-shaped sliding hole. The magnet slides through the arc-shaped sliding hole and is fixedly connected to the arc-shaped rack. A first Hall element circuit board and a second Hall element circuit board are respectively installed on both sides of the magnet and mounted on the support. The first Hall element circuit board and the second Hall element circuit board are respectively disposed at both ends of the arc-shaped sliding hole.

[0013] Preferably, the magnet is cylindrical.

[0014] Preferably, the controller is electrically connected to the first Hall element circuit board, the second Hall element circuit board, and the drive motor via wires.

[0015] Preferably, the connecting assembly further includes an outer cover, which covers the support, and the fixing base, left and right swing assembly, connecting assembly, angle detection assembly and controller are located inside the outer cover.

[0016] An electric fan includes a fan head, a support assembly, and an angle-adjustable oscillating assembly as described above. The fan head is mounted on the outer cover, and the mounting base is fixedly mounted on the top of the support assembly.

[0017] Preferably, the support assembly includes a base and a telescopic rod, the telescopic rod being mounted on the top of the base, and the fixing seat being mounted on the top of the telescopic rod.

[0018] The technical solution provided by this utility model can include the following beneficial effects:

[0019] The angle detection component can detect the rotation angle of the connecting component. The controller uses the rotation angle detected by the angle detection component to determine whether the rotation angle of the connecting component meets the preset angle. If it does not meet the preset angle, the controller controls the left and right oscillation components to adjust the rotation angle of the connecting component to the preset angle. This allows the rotation angle of the electric fan to be adjusted as needed, avoiding the phenomenon that the user does not get a breeze for a long period of time due to the oscillation angle being too large, thus improving the user experience.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The following is in conjunction with the accompanying drawings. Figures 1 to 3 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0028] like Figure 1-3 As shown, an angle-adjustable oscillation assembly includes a fixed base 1, a left and right oscillation assembly 2, a connecting assembly 3, an angle detection assembly 4, and a controller.

[0029] The connecting component 3 is rotatably mounted on the top of the fixed base 1, the left and right swaying component 2 and the angle detection component 4 are disposed on the connecting component 3, and the controller is electrically connected to the left and right swaying component 2 and the angle detection component 4 through wires;

[0030] The left and right swaying assembly 2 is used to drive the connecting assembly 3 to rotate left and right relative to the fixed base 1. The angle detection assembly 4 is used to detect the rotation angle of the connecting assembly 3. The controller is used to control the left and right swaying assembly 2 to work according to the rotation angle detected by the angle detection assembly 4.

[0031] This solution uses the angle detection component 4 to detect the rotation angle of the connecting component 3. The controller uses the rotation angle detected by the angle detection component 4 to determine whether the rotation angle of the connecting component 3 meets the preset angle. If it does not meet the preset angle, the controller controls the left and right oscillation components 2 to adjust the rotation angle of the connecting component 3 to the preset angle. This allows the rotation angle of the electric fan to be adjusted as needed, avoiding the phenomenon that the user will not be able to blow air for a long period of time due to the oscillation angle being too large, thus improving the user experience.

[0032] like Figure 1 As shown, the connecting component 3 includes a support 31 and a rotating shaft. The rotating shaft is coaxially and rotatably mounted on the top end of the fixed base 1, and the support 31 is coaxially and fixedly mounted on the top end of the rotating shaft.

[0033] Specifically, the support 31 can drive the rotating shaft to rotate at the top of the fixed seat 1, thereby causing the support 31 to rotate left and right relative to the fixed seat 1.

[0034] like Figure 1-2 As shown, the left and right swaying assembly 2 includes a drive motor 21, which is fixedly installed on the support 31. The output shaft of the drive motor 21 is coaxially connected to a gear 22, and one side of the gear 22 is meshed with an arc-shaped rack 23, which is fixedly installed on the fixed base 1.

[0035] like Figure 1 As shown, the arc-shaped rack 23 is coaxially arranged with the rotating shaft.

[0036] Specifically, the drive motor 21 drives the gear 22 to rotate. Since the arc-shaped rack 23 is fixed on the fixed base 1 and coaxial with the rotating shaft, and the support 31 can rotate left and right relative to the fixed base 1, the gear 22 rotates around the axis of the arc-shaped rack 23 under the drive of the drive motor 21, and the gear 22 is always meshed with the arc-shaped rack 23, thereby driving the support 31 to rotate left and right relative to the fixed base 1.

[0037] like Figure 2As shown, the angle detection component 4 includes a magnet 43. An arc-shaped sliding hole 311 is provided on the upper surface of the support 31. The magnet 43 is slidably inserted through the arc-shaped sliding hole 311 and fixedly connected to the arc-shaped rack 23. A first Hall element circuit board 41 and a second Hall element circuit board 42 are respectively installed on both sides of the magnet 43 and mounted on the support 31. The first Hall element circuit board 41 and the second Hall element circuit board 42 are respectively disposed at both ends of the arc-shaped sliding hole 311.

[0038] Specifically, the distance the magnet 43 moves is detected by the Hall elements on the first Hall element circuit board 41 and the second Hall element circuit board 42. The controller adjusts the moving distance of the magnet 43 to a preset value based on the detected moving distance, thereby adjusting the rotation angle of the magnet 43 to achieve the adjustment of the angle of the fan head 5.

[0039] like Figure 2 As shown, the magnet 43 is cylindrical in shape.

[0040] Specifically, the cylindrical shape of magnet 43 allows it to slide more smoothly within the arc-shaped sliding hole 311.

[0041] like Figure 1-2 As shown, the controller is electrically connected to the first Hall element circuit board 41, the second Hall element circuit board 42, and the drive motor 21 via wires.

[0042] like Figure 1-3 As shown, the connecting component 3 also includes an outer cover 32, which covers the support 31. The fixed base 1, the left and right swaying component 2, the connecting component 3, the angle detection component 4 and the controller are located inside the outer cover 32.

[0043] Specifically, the outer cover 32 can protect the fixed base 1, the left and right sway assembly 2, the connecting assembly 3, the angle detection assembly 4 and the controller, and can also improve the aesthetics of the device.

[0044] like Figure 1-3 As shown, an electric fan includes a fan head 5, a support assembly 6, and an adjustable oscillating assembly as described above. The fan head 5 is mounted on the outer cover 32, and the fixing base 1 is fixedly mounted on the top of the support assembly 6.

[0045] Specifically, the fan head 5 is supported by the support component 6. The fan head 5 is mounted on the outer cover 32. The left and right oscillation component 2 drives the outer cover 32 of the connecting component 3 to rotate left and right, thereby causing the fan head 5 to rotate left and right to blow air.

[0046] like Figure 3As shown, the support assembly 6 includes a base 61 and a telescopic rod 62. The telescopic rod 62 is installed on the top of the base 61, and the fixed seat 1 is installed on the top of the telescopic rod 62.

[0047] Specifically, the height of the fan head 5 can be adjusted by the telescopic rod 62 to suit the usage needs of people of different heights.

[0048] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without any inventive effort, and these embodiments will all fall within the scope of protection of this utility model.
