Problems solved by technology

"However, the angle of the oscillating structure is small, which is inconvenient to apply to a wider range, and if the center of gravity is unstable during the oscillating project of the electric fan, it is easy to tip over and damage the machine or injure consumers.
[0003] In addition, if the air intake chamber of the fan assembly is connected to the control board, the airflow and impurities generated during the operation of the fan assembly will affect the service life of the control board, or the installation of the fan assembly will also affect the setting of the control board, and The connection between the fan assembly and the control board in the base is inconvenient to install

Embodiment 1

[0034] like figure 1Shown, a kind of electric fan, take the electric fan is a bladeless electric fan as example, described bladeless electric fan comprises base and is arranged on the fan head 3 above the base, and described fan head 3 is used for wind, so A control panel 6 is arranged in the base, wherein the base includes a fan mounting seat 1 and a base 2 which are split parts, the fan mounting seat 1 has a hollow first cavity 9, and the first cavity The body 9 is provided with a fan assembly 4 connected to the control board 6, and the top of the first cavity is connected to the fan head 3. The fan assembly 4 is used to suck air into the fan mounting base 1, and then draw the air from the fan head 3 spray out, and finally form an uninterrupted flow of cold air, the base 2 cooperates with the bottom of the fan mounting base 1 to form a second cavity 10, and the control board 6 is located in the second cavity 10 At this time, the control board 6 and the fan assembly 4 are re...

Embodiment 2

[0050] Based on the structure of embodiment 1, such as image 3 , 4As shown, in order to facilitate connecting the connecting rod 51 with the fan mounting base 1, a driving assembly connected to the control board 6 is also provided in the second cavity 10, the driving assembly includes a motor 5 and a connecting rod 51, the One end of the connecting rod 51 is connected to the fan mounting base 1, and the other end is connected to the motor 5. The base 2 is provided with a mounting hole 27, and the mounting hole 27 is located at the movement of one end of the connecting rod 51. Below the path, the first screw passes through the installation hole 27 to connect one end of the connecting rod 51 with the stud 13 at the bottom of the fan installation base 1 . By setting the mounting hole 27 on the moving path of the connecting rod, it is only necessary to control the connecting rod 51 to move above the mounting hole 27, and then connect the connecting rod 51 to the fan mounting bas...

Abstract

The present invention relates to a household appliance, in particular to an electric fan, which includes a base and a fan head located above the base. A control panel is provided in the base, and the base includes a fan installation that is a separate piece. The fan mounting base has a hollow first cavity, a fan assembly connected to the control board is provided in the first cavity, and the top of the first cavity is connected to the fan head, and the base is connected to the fan head. The bottom of the fan mounting base cooperates to form a second cavity, and the control panel is located in the second cavity. The fan mounting base rotates relative to the base to drive the fan head to rotate. It is provided with a first installation shaft extending into the second cavity, and also includes a connecting piece that resists the base and is connected to the first installation shaft.

Description

technical field [0001] The invention relates to household appliances, in particular to an electric fan. Background technique [0002] Another patent application number is CN201610352761.2, and the invention name is "Fan". This patent application discloses a bladeless fan. The design idea of ​​the swing of section 52, "body 12 includes a generally cylindrical main body section 50 mounted on a generally cylindrical lower body section 52 . . . the lower body section 52 Including the aforementioned user interface and control circuitry, generally indicated at 62, for controlling the various functions of the fan 10 in response to operation of the user interface. The lower body section 52 also houses a A mechanism that swings on the lower body section 52. The operation of the swing mechanism is controlled by the control circuit 62 in response to the pressing of the appropriate button on the remote controller by the user. Each of the main body section 50 relative to the lower body ...
