[0034] The utility model provides a floor fan.

[0035] In the embodiment of the present utility model, Figures 1 to 6As shown, the floor fan includes a support base 10, a rotating frame 20 and a fan device 30: the support base 10 is provided with an electric control device; the rotating frame 20 includes a first shell 21 and a second shell 22, the first shell 21 is annular, the second shell 22 is columnar, the second shell 22 is fixed on the lower side of the first shell 21, and the second shell 22 is rotatably installed on the upper end of the support base 10; the fan device 30 includes a motor housing 311, a fan motor 32 and a fan blade 33, the motor housing 311 is rotatably installed at the annular hole of the first shell 21, the rotation axis of the motor housing 311 is perpendicular to the rotation axis of the second shell 22, the motor is installed in the motor housing 311, and is connected to the electric control device, and the fan blade 33 is installed on the rotating shaft of the fan motor 32.

[0036] Specifically, when in use, the rotating shaft of the fan motor 32 rotates, driving the fan blades 33 to rotate, and the fan blades 33 drive the air flow to form a blowing, and the blowing angle of the fan blades in the horizontal direction can be adjusted by rotating the rotating frame 20. In addition, the motor housing 311 can be rotated to adjust the pitch angle of the motor housing 311 to adjust the up and down blowing angle of the fan device 30.

[0037] The utility model is provided with a rotatable rotating frame 20 at the upper end of the support, and a rotatable fan device 30 is provided in the rotating frame 20, wherein the rotating frame 20 includes a first shell 21 and a second shell 22, the first shell 21 is annular, the second shell 22 is columnar, the second shell 22 is fixed on the lower side of the first shell 21, and the second shell 22 is rotatably installed on the upper end of the support base 10, the fan device 30 includes a motor housing 311, a fan motor 32 and a fan blade 33, the motor housing 311 is rotatably installed at the annular hole of the first shell 21, the rotation axis of the motor housing 311 is perpendicular to the rotation axis of the second shell 22, the motor is installed in the motor housing 311, and the fan blade 33 is installed on the rotating shaft of the fan motor 32. In this way, when the rotating seat is rotated, the fan device 30 will rotate together, so that the blowing angle of the fan blade 33 in the horizontal direction changes. In addition, when the motor housing 311 is rotated in the first shell 21, the pitch angle of the fan blade 33 changes. In this way, the blowing angle of the fan blade 33 can be adjusted in the horizontal direction and the up and down direction at the same time. The blowing line of the fan device 30 can be adjusted by 30°. The fan device 30 has a large blowing range, and it is more convenient for users to use.

[0038] In addition, the annular first shell 21 has a stronger structure, making the structure of the rotating frame 20 more stable, while preventing external objects from hitting the fan device 30 from above, making the floor fan safer when in use.

[0039] In some embodiments, the floor fan includes a first drive motor, which is disposed in the second housing 22 and connected to the electric control device. The shaft of the first drive motor extends toward the support seat 10 and is provided with a first gear 41. A second gear 42 is fixed to the upper end of the support seat 10, and the first gear 41 is meshed with the second gear 42. Specifically, when in use, the shaft of the first drive motor rotates to drive the first gear 41 to rotate, and the second gear 42 is fixed to the upper end of the support seat 10, so that the first gear 41 will rotate around the second gear 42, so that the rotating seat fixed to the first drive motor rotates relative to the support seat 10, so that when the fan device 30 is blowing, the rotating frame 20 drives the fan device 30 to rotate at the same time, and the fan device 30 can blow air to multiple positions in the horizontal direction, thereby increasing the blowing range of the fan device 30.

[0040] In some embodiments, two bearings are provided on opposite sides of the inner side of the first housing 21, and the rotation axes of the two bearings are the same, and the motor housing 311 is rotatably mounted on the rotating frame 20 through the two bearings. Specifically, in this way, both sides of the motor housing 311 are mounted on the inner side of the first housing 21, and compared with only one bearing being provided, only one side of the motor housing 311 is mounted on the first housing 21, so that the mounting structure of the motor housing 311 is more reliable, and the motor housing 311 is more stable when rotating.

[0041] In some embodiments, the floor fan includes a second drive motor, which is disposed in the motor housing 311 and connected to the electronic control device. The bearing of the second drive motor extends to the first shell 21 and is transmission-connected to the first shell 21. The second drive motor is used to drive the motor housing 311 to rotate relative to the first shell 21.

[0042] Specifically, when in use, the fan device 30 blows air, and at the same time, the second drive motor drives the motor housing 311 to rotate relative to the rotating base, so that the fan device 30 pitches up and down while blowing air, and the fan device 30 can blow air to multiple positions.

[0043] It is worth mentioning that when in use, the second drive motor and the second drive motor cooperate to rotate, and while the fan motor 32 blows air, the blowing angle is adjusted left and right and in pitch at the same time, so that the blowing angle of the fan device 30 is larger, and the user's practical experience is better.

[0044] In some embodiments, an operation panel is provided on the top of the first housing 21, and the operation panel is connected to the electric control device. Specifically, the operation panel is provided with a touch button, an adjustment knob or a key switch to control the fan device 30 to turn on or off, or to control the first drive motor and the second drive motor to drive the fan device 30 to rotate, and to control the blowing direction of the fan device 30. When the remote control is out of power or the ambient sound is noisy and cannot be voice-controlled, it can be controlled by adjusting the knob and the key switch, and the mechanical control of the adjustment knob and the key switch is more reliable.

[0045] In some embodiments, the electric control device has a voice control module, and the rotating frame 20 is provided with a microphone 23, which is connected to the electric control device. Specifically, the user can control the fan device 30 to turn on or off by voice, or control the first drive motor and the second drive motor to drive the fan device 30 to rotate by voice, and control the blowing direction of the fan device 30, which is more convenient to use.

[0046] In some embodiments, the electric control device has a wireless module, and the floor fan also includes a remote controller, which is wirelessly connected to the wireless module. Specifically, the remote controller can wirelessly control the fan device 30 to turn on or off, or control the first drive motor and the second drive motor to drive the fan device 30 to rotate, and control the blowing direction of the fan device 30, which is convenient to use. Furthermore, the user can also use a mobile phone to connect to the wireless module, and wirelessly control the fan device 30 and the mosquito-repellent liquid heating device to turn on, off or rotate through the mobile phone.

[0047] In some embodiments, the support base 10 includes a support rod 11 and a base 12, the support rod 11 is mounted on the base 12, and the second housing 22 is mounted on the support rod 11. Specifically, the support rod 11 has a certain length, so that the rotating frame 20 and the fan device 30 are located at a higher position when in use. Compared with a table fan without a support rod 11 that needs to be placed on a table for use, a floor fan is more convenient when in use. Further, the support rod 11 can be set as a telescopic rod. In addition, in other embodiments, the support rod may not be set.

[0048] In some embodiments, the motor housing 311 includes a first mesh cover 312 and a housing 311. The housing 311 is cylindrical and has a radial dimension that is smaller than the inner diameter of the first shell 21. The first mesh cover 312 is disposed at the rear end of the housing 311. The first mesh cover 312 is provided with a mounting shell 3121. The fan motor 32 is mounted on the mounting shell 3121. The radial dimension of the housing 311 is larger than the radial dimension of the fan blades 33. The fan blades 33 are located inside the housing 311.

[0049] Specifically, the cylindrical housing 311 is located outside the fan blades 33 to surround the fan blades 33, so that the wind blown by the fan blades 33 is more concentrated, and the user can feel a stronger wind when using. In addition, the first net cover 312 is located at the rear side of the housing 311, which can prevent objects from entering the housing 311 from the rear side of the housing 311 and hitting the high-speed rotating fan blades 33, and will not affect the airflow entering from the rear side of the housing 311. Further, the first net cover 312 and the mounting shell 3121 can be an integrated structure.

[0050] In some embodiments, a second mesh cover 313 is provided at the front end of the housing 311, and the fan blades 33 are located between the first mesh cover 312 and the second mesh cover 313. Specifically, the first mesh cover 312 is located at the front side of the fan blades 33, which prevents the user from accidentally touching the high-speed rotating fan blades 33 from the front side of the fan device 30 and getting injured, and also prevents the high-speed rotating fan blades 33 from hitting objects and getting damaged.

[0051] In some embodiments, the mounting shell 3121 is provided with a heat dissipation through hole 3122, and the heat dissipation through hole 3122 is arranged toward the fan motor 32. Specifically, when the fan motor 32 is in operation, the temperature will be relatively high, and the provision of the first heat dissipation hole allows the external room temperature air to enter the mounting shell 3121, cool down the fan motor 32 with a relatively high temperature, and make the fan motor 32 operate more stably.

[0052] In some embodiments, the second housing 22 is provided with a power interface, and wiring channels are provided inside the rotating frame 20, on the rear side of the motor housing 311, and at the connection between the rotating frame 20 and the motor housing 311, and the wiring channels are connected to the mounting shell 3121. Specifically, the electrical connection line is connected to the first drive motor through the second housing 22, and then connected to the second drive motor and the fan motor 32 through the interior of the rotating frame 20 and the rear side of the housing 311, so that the electrical connection line will not be exposed to the outside, which is more convenient when used.
