Abstract
The utility model discloses a kind of fan head swinging adjustable angle structure, it includes head-shaking motor, gear, continuous motion stem; Described head-shaking motor has a downward output shaft, and described gear is fixed on output the tip of the axis, and described gear bottom surface is provided with multiple screw; Described continuous motion stem one end arranges multiple through hole matched with screw, and the other end is connected with fan retaining bracket; One bolt lock, one group of relative screw located therein and through hole; By said structure, the utility model can regulate the panning angle of fan within the specific limits, improves the travelling comfort of user, also more meets energy-conserving and environment-protective requirement simultaneously.
Description
Technical field
The utility model relates to a kind of electric fan parts, refers in particular to a kind of fan head swinging adjustable angle structure.
Background technique
Electric fan is stressed in magnetic field by electric coil, and coil rotor drives flabellum to rotate, and brings breezy cool breeze to user.The fan kind of family expenses is various, and desk fan wherein and stand fan also have oscillating function.Current fan head-shaking device generally adopts crank room structure, and its rotation angle is limited, and maximum rotation angle and rotation amplitude are fixing, can not again adjust after dispatching from the factory,
And common oscillating fan is the interior round air-supply of angle of fixing about 90 degree.When a small amount of people dries, panning angle is excessive, and two-way time is long, and in unwanted angle, air-supply can cause the decline of Consumer's comfort level; When a large amount of people dries, panning angle is too small, and some people blows less than wind, just needs to use more fan; Consumer can deliberately remove because blow-time is too short the power adding big fan again simultaneously, virtually also result in the wasting of resources, does not also meet the energy-conserving and environment-protective requirement that Present Global is advocated.
In view of this, the design people for said fans panning angle structural design not being attained perfect caused many disappearances and inconvenience, and deeply conceives, and active research improvement has a fling at and development and Design goes out this case.
Model utility content
The purpose of this utility model is to provide a kind of fan head swinging adjustable angle structure, can regulate the panning angle of fan within the specific limits, improves the travelling comfort of user, also more meets energy-conserving and environment-protective requirement simultaneously.
In order to reach above-mentioned purpose, solution of the present utility model is:
A kind of fan head swinging adjustable angle structure, it includes head-shaking motor, gear, continuous motion stem; Described head-shaking motor has a downward output shaft, and described gear is fixed on output the tip of the axis, and described gear bottom surface is provided with multiple screw; Described continuous motion stem one end arranges multiple through hole matched with screw, and the other end is connected with fan retaining bracket; One bolt lock, one group of relative screw located therein and through hole.
Each described screw is different to the distance in the gear center of circle.
The quantity of described screw is three, and lays respectively at three with on the concentric circle that is the center of circle of the gear center of circle.
Described in adjacent two, concentrically ringed spacing is equal.
Three described screws are positioned on same tooth radius.
After adopting said structure, the utility model fan head swinging angle establishes the screw of diverse location and through hole to carry out the crank up distance of adjusting gear and continuous motion stem by bolt lock, to realize the function regulating fan head swinging angle, effectively promotes the travelling comfort of Consumer; Fan head swinging angle can be reduced, shorten air-supply stand-by period during fan head swinging, invalid is not blown, when low-angle air supply pattern work, fall one grade of air quantity and also can obtain more abundant air quantity; Fan head swinging angle can be expanded, ensure also all to blow to wind on a large scale, also more meet energy-conserving and environment-protective requirement simultaneously.

Embodiment
In order to explain the technical solution of the utility model further, below by specific embodiment, the utility model is elaborated.
A kind of fan head swinging adjustable angle structure, it includes fan electromotor 1, fan retaining bracket 2, head-shaking motor 3, gear 4, continuous motion stem 5; The coupling shaft 11 that fan electromotor 1 has fan attachment blade and the back shaft 12 be fixedly connected with fan retaining bracket 2, described head-shaking motor 3 has a downward output shaft 31, described gear 4 is fixed on the end of output shaft 31, and described gear 4 bottom surface is provided with multiple screw 41; Described continuous motion stem 5 one end arranges multiple through hole 51 matched with screw 41, and the other end is connected with fan retaining bracket 2; One bolt 6 is locked on wherein one group of relative screw 41 and through hole 51.
The utility model fan head swinging angle establishes the screw 41 of diverse location and through hole 51 to carry out the crank up distance of adjusting gear and continuous motion stem by bolt 6 lock, to realize the function regulating fan head swinging angle, effectively promotes the travelling comfort of Consumer; Fan head swinging angle can be reduced, shorten air-supply stand-by period during fan head swinging, invalid is not blown, when low-angle air supply pattern work, fall one grade of air quantity and also can obtain more abundant air quantity; Fan head swinging angle can be expanded, ensure also all to blow to wind on a large scale, also more meet energy-conserving and environment-protective requirement simultaneously.
The each described screw 41 of the utility model fan head swinging angle is different to the distance in gear 4 center of circle, and when ensureing to adjust to each screw 41, fan head swinging angle is all different, more meets user and uses.
The preferred forms (referring to Fig. 3) of the utility model fan head swinging angle, the quantity of described screw 41 is three, and lays respectively at three with on the concentric circle that is the center of circle of gear 4 center of circle; Described in adjacent two, concentrically ringed spacing is equal; Three described screws 41 are positioned on same tooth radius; Fan can be made to have three kinds of panning angles (small angle shake the head shake the head scope and wide-angle of scope, general angle to shake the head scope) with the requirement of applicable user.
Above-described embodiment and accompanying drawing non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field, to its suitable change done or modification, all should be considered as not departing from patent category of the present utility model.
