Problems solved by technology

[0002]The existing traditional fan generally adopts the structure of oscillating head, and the air inlet is open when it is in use and in the shutdown state. Since the air inlet is open in the shutdown state, some miscellaneous Objects and dust will enter the inside of the fan through the open air inlet in the shutdown state, which will affect the performance of the mechanical components and electronic components inside the fan, and even cause the fan to not work normally and shorten the service life of the fan

Embodiment 1

[0023] The structural representation of the embodiment of the present invention is as image 3 , 4 , 5, and 6, the fan structure of the present invention includes a base 2 and a housing 1 mounted on the base 2, wherein the base 2 and the housing 1 are provided with an air inlet that can open the fan and close the air inlet of the fan lifting mechanism.

[0024] Above-mentioned elevating mechanism comprises drive motor 3 and its transmission mechanism that converts rotary motion into linear motion, wherein drive motor 3 is installed on the base 2, and the active part 4 of transmission mechanism is connected with the output shaft of drive motor 3, and the transmission mechanism The follower 6 is connected to the housing 1 . In this embodiment, the above-mentioned transmission mechanism for converting rotational motion into linear motion is a worm and rack transmission mechanism. The driving part 4 of the transmission mechanism is a worm, and the driven part 6 is a rack. The mo...

Embodiment 2

[0032] The structure of the embodiment of the present invention is the same as that of Embodiment 1, except that the above-mentioned transmission mechanism that converts rotary motion into linear motion is a rack and pinion transmission mechanism, the driving part 4 of the transmission mechanism is a gear, and the driven part 6 is a rack , the modulus of the gear and the rack is the same.

Abstract

The invention discloses a fan structure which comprises a base (2) and a housing (1) arranged on the base (2), wherein an air inlet capable of opening a fan and a lifting mechanism for closing the air inlet of the fan are arranged between the base and the housing. In the invention, the structure that the air inlet capable of opening the fan and the lifting mechanism for closing the air inlet of the fan are arranged between the base and the housing is adopted, when the fan is switched on, the housing is lifted, and the air inlet is exposed; and when the fan is switched off, the housing falls off and the air inlet is closed. The invention can avoid impurities and dust from entering inside the fan through the opening air inlet in the stopped state of the fan, can effectively protect use properties of mechanical members and electronic elements inside the fan and prolong the service life of the fan. The fan structure has a reasonable design and is convenient and practical.

Description

technical field [0001] The invention relates to a fan structure, especially a fan structure provided with a lifting mechanism. The lifting mechanism enables the fan casing to be raised and lowered. When the fan casing rises, its air inlet is opened, and when the fan casing is lowered, the air inlet is closed, which belongs to the fan structure. innovative technology. Background technique [0002] The existing traditional fan generally adopts the structure of shaking head, and the air inlet is open in use and shutdown state. Since the air inlet is open in the shutdown state, some sundries and dust will enter the fan through the open air inlet in the shutdown state. , so that it will affect the performance of the mechanical components and electronic components inside the fan, and even cause the fan to not work normally and shorten the service life of the fan. Contents of the invention [0003] The object of the present invention is to provide a fan structure that can effec...
