[0002] The synchronous motors used in the air supply devices of electrical equipment are basically single-shaft and single-speed. Each oscillating structure requires a motor to drive it. When supplying air at multiple angles, multiple motors are required, which significantly increases the cost. Utility Model Content

[0003] In view of this, the present invention provides a motor structure, an air supply device and electrical equipment, which at least solves the problem that multi-angle air supply requires matching multiple motors and increases costs.

[0009] Beneficial effects: The driving force of the motor is transmitted to the first gear set through the rotating gear, and then to the first output shaft and the second output shaft respectively through the first output gear and the second output gear of the first gear set.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0074] The following is combined Figures 1 to 9 The following describes embodiments of the present invention.

[0075] According to embodiments of the present invention, on the one hand, such as Figures 1 to 5 As shown, a motor structure is provided, including:

[0076] Rotor gear 9;

[0077] The first gear set 3 includes at least two transmission gears, and the rotor gear 9 meshes with one of the transmission gears; the at least two transmission gears include a first output gear and a second output gear;

[0078] The first output shaft 1 is connected to the first output gear via a transmission.

[0079] The second output shaft 2 is connected to the second output gear; the second output shaft 2 forms a non-zero angle with the first output shaft 1.

[0080] The driving force of the motor 10 is transmitted to the first gear set 3 through the rotating gear, and then to the first output shaft 1 and the second output shaft 2 through the first output gear and the second output gear of the first gear set 3 respectively. Since the first output shaft 1 and the second output shaft 2 are at a non-zero angle, the driving force of the motor 10 can be transmitted to different motion planes. After the air supply device adopts the motor structure of this utility model, it can realize air supply at multiple angles and cover a larger sweeping range with only one motor 10, thereby reducing the number of motors and effectively controlling costs.

[0081] It should be noted that the included angle between the first output shaft 1 and the second output shaft 2 can be designed and selected specifically according to the size of the arrangement space, the preset sweeping range and sweeping mode, etc.

[0082] In some embodiments, the first output shaft 1 and the second output shaft 2 form a 180° angle.

[0083] The first output shaft 1 and the second output shaft 2 are positioned in opposite directions, which facilitates oscillating motion within two perpendicular working planes, maximizing the air delivery range. Furthermore, it saves space in the radial direction, effectively controlling the size of the air delivery device.

[0084] In some embodiments, the first gear set 3 further includes:

[0085] The bracket 4 has at least two mounting shafts 41 on its first side, and all the transmission gears are respectively mounted on the corresponding mounting shafts 41. Specifically, the number of mounting shafts 41 is determined according to the number of transmission gears.

[0086] All transmission gears are mounted on bracket 4 via mounting shaft 41, which facilitates the arrangement and assembly of transmission gears in the first gear set 3.

[0087] In some embodiments, the motor structure further includes:

[0088] like Figure 6 The housing 51 shown has a receiving cavity, in which the rotor gear 9 and the first gear set 3 are both disposed; the bottom surface of the housing 51 has a housing shaft hole 511 through which one of the first output shaft 1 or the second output shaft 2 passes; the coil of the motor 10 and the rotor magnet 7 are also disposed in the receiving cavity.

[0089] like Figure 7 The cover 52 shown is fastened to the opening of the housing 51 away from the bottom surface; the cover 52 has a cover shaft hole 521 through which one of the first output shaft 1 or the second output shaft 2 passes.

[0090] Shaft holes are provided on the housing 51 and the cover 52 of the motor structure, which is simple in structure and allows the first output shaft 1 and the second output shaft 2 to easily extend from the housing 5 of the motor 10 structure, thereby realizing multi-angle air supply.

[0091] In some embodiments, as shown in the figure, the first gear set 3 includes a first gear 31, a second gear 32, a third gear 33, and a fourth gear 34, and the rotor gear 9, the first gear 31, the second gear 32, the third gear 33, and the fourth gear 34 mesh with each other in sequence; the second output shaft 2 is drivenly connected to the third gear 33, and the second output shaft 2 is drivenly connected to the fourth gear 34.

[0092] The rotor gear 9 achieves a first-stage reduction with the first gear 31 of the first gear set 3; the first gear 31 achieves a second-stage reduction with the second gear 32; the second gear 32 achieves a third-stage reduction with the third gear 33; the third gear 33 achieves a fourth-stage reduction with the fourth gear 34 and the third gear 33 achieves a fourth-stage reduction with the second output shaft 2; and the fourth gear 34 achieves a fifth-stage reduction with the first output shaft 1. Through multi-stage reduction, the reduction ratio can be adaptively adjusted and matched with the setting positions of the two output shafts.

[0093] In some embodiments, the first output shaft 1 is provided with a first transmission tooth; the second output shaft 2 is provided with a second transmission tooth, and the first transmission tooth and the second transmission tooth respectively mesh with the corresponding transmission gear.

[0094] By setting transmission teeth on the output shaft, the transmission teeth on the output shaft can serve as reduction teeth, reducing the number of reduction gears and making the structure more compact.

[0095] According to an embodiment of the present invention, another aspect provides an air supply device, comprising:

[0096] Motor structure;

[0097] The first oscillating mechanism 200 is connected to the power output end of the first output shaft 1 via a transmission connection.

[0098] The second oscillating mechanism 300 is connected to the power output end of the second output shaft 2 via a transmission connection.

[0099] The first oscillating mechanism 200 and the second oscillating mechanism 300 of the air supply device are respectively connected to the first output shaft 1 and the second output shaft 2. Since the first output shaft 1 and the second output shaft 2 are at a non-zero angle, the driving force of the motor 10 can be transmitted to the first oscillating mechanism 200 and the second oscillating mechanism 300 in different motion planes. This allows the air supply device to achieve air supply at different angles with only one motor 10, increasing the air supply range and improving the user experience.

[0100] In one alternative implementation, the first swaying mechanism 200 includes:

[0101] The rotating disk is connected to the power output end of the first output shaft 1; the second oscillating mechanism 300 is disposed on the rotating disk.

[0102] Beneficial effects: The rotating disc can rotate in the horizontal plane, realizing air supply in a 360-degree range around the air supply device.

[0103] In some embodiments, the second swaying mechanism 300 includes:

[0104] The second gear set 100 is connected to the second output shaft 2 for transmission.

[0105] The second gear set 100 changes the oscillation direction of the fan head, enabling 360-degree horizontal airflow while simultaneously allowing the air supply device to sweep in the pitch direction. The sweeping range can cover the user's feet and head, improving user comfort.

[0106] It should be noted that the second gear set 100 can change the transmission direction, so that the fan head can rotate with the first oscillating mechanism 200 while also rotating with the second oscillating mechanism 300, thus covering a larger sweeping range and sweeping angle.

[0107] According to an embodiment of the present invention, in another aspect, an electrical device is also provided, including the above-mentioned air supply device.

[0108] Since the electrical equipment includes the air supply device of this utility model, it has the same technical effect as the air supply device, and will not be described in detail here.

[0109] The electrical device is a fan or an electric heater.

[0110] The air supply device of this utility model is used in fans and electric heaters. It can achieve multi-angle air sweeping simultaneously with one motor 10, reducing the number of motors and effectively controlling costs. At the same time, it makes the product structure more compact and meets users' needs for multi-angle and wide-range air supply in fans and electric heaters.

[0111] As an embodiment of this utility model, Figure 8 and Figure 9A fan is provided, comprising a horizontal oscillation mechanism and a pitch oscillation mechanism. The motor structure includes a first output shaft 1 and a second output shaft 2. The first output shaft 1 is driven by the horizontal oscillation mechanism, and the second output shaft 2 is driven by the pitch oscillation mechanism. The rotor gear 9 of the motor 10 is connected to the first output shaft 1 and the second output shaft 2 respectively via a first gear set 3. The first gear set 3 is fixed on a bracket 4, which is in contact with a coil bracket 6 for fixing enameled wire. The first output shaft 1 extends from the cover shaft hole 521 at the cover 52, and the second output shaft 2 extends from the housing shaft hole 511 on the housing 51. The shaft ends are equipped with high-strength steel gears (first transmission gear 11 and second transmission gear 21), which mesh with corresponding transmission gears on the first gear set 3. The rotor gear 9 is directly connected to the rotor of the motor 10, outputting the initial speed. After one to four speed reduction stages, it is connected to the second output shaft 2; after one to five speed reduction stages, it is connected to the first output shaft 1. If the total reduction ratio of the first to fourth stage reduction gears is 1:50, and the total reduction ratio of the first to fifth stage reduction gears is 1:100, and the rotor gear 9 rotates at 300 rpm, then the output speed of the second output shaft 2 is 6 rpm, and the output speed of the first output shaft 1 is 3 rpm. The first output shaft 1 extends downwards, and when it rotates, it drives the entire machine to complete the left and right oscillation motion via a crank. The second output shaft 2 extends upwards, connected to an external coaxial transmission gear. This externally mounts the gear set of the second oscillation mechanism 300, transmitting power through the power gears A, B, and C. The power gear C is designed with multiple teeth on one shaft; besides transmitting power, it also connects to the motion track (designed as a double-track toothed chain) to change the direction of the machine head's movement, thereby achieving the pitching and oscillation of the entire machine.

[0112] Because the two output shafts (dual shaft extensions) drive two sets of oscillating structures, and with different oscillating structure designs, the machine head can pitch (up and down) and sway left and right. When the output torque is large, it is necessary to select appropriate gear materials, use high-strength materials, and increase the gear thickness to effectively avoid the risk of tooth breakage during operation.

[0113] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by this application.
