Detailed Description
The technical scheme of the invention is further described below by the specific embodiments with reference to the accompanying drawings.
The embodiment discloses a potentiometer linkage adjustment mechanism and hair-dryer, and the hair-dryer includes casing, handle and potentiometer linkage adjustment mechanism. As shown in fig. 1 to 5, the potentiometer linkage adjustment mechanism includes a rotary potentiometer 1, a trigger 2 for driving and adjusting the angle of the rotary potentiometer 1, and a base 3 for mounting the rotary potentiometer 1, wherein the rotary potentiometer 1 is mounted in a housing or a handle, and the trigger 2 is at least partially disposed outside the housing or the handle (for example, a small bump at the end of the trigger 2 is disposed outside the housing or the handle) so as to be convenient for a user to toggle.
The trigger 2 is in a strip structure, a trigger mounting hole 22 for penetrating through a trigger rotating shaft is arranged at the approximate middle position of the trigger 2, and a trigger gear 21 consisting of a plurality of connected gear teeth is formed at one end of the trigger 2; a potentiometer gear 11 is provided on the outer peripheral surface of the rotary potentiometer 1. The potentiometer gear 11 of the rotary potentiometer 1 is meshed with the trigger gear 21 of the trigger 2, and the rotation radius of the trigger gear 21 is larger than that of the potentiometer gear 11, namely, a distance A is formed between the trigger gear 21 and the trigger mounting hole 22, a distance B is formed between the potentiometer gear 11 and the potentiometer mounting hole 12 of the rotary potentiometer 1 for penetrating through the potentiometer rotating shaft, and the distance A is larger than the distance B. Thus, the angular velocity of the trigger gear 21 during adjustment is less than the angular velocity of the potentiometer gear 11. Preferably, the transmission ratio of the trigger gear 21 to the potentiometer gear 11 is 1:3.
The trigger gear 21 is meshed with the potentiometer gear 11, and the angular velocity of the trigger gear 21 is smaller than that of the potentiometer gear 11, so that the trigger 2 can be rotated by a small angle to drive the rotary potentiometer 1 to rotate by a large angle, and large-angle adjustment of the rotary potentiometer 1 in a small space range is realized. In the potentiometer linkage adjusting mechanism of the embodiment, the rotation angle of the trigger 3 is less than or equal to 45 degrees, the adjustment angle of the rotary potentiometer 1 is more than or equal to 60 degrees, the utilization rate of the potentiometer gear 11 is higher, and the gears can be more, so that the blower can have more working modes or functions, and the application range is wider.
The space for installing the potentiometer linkage adjusting mechanism in the blower is smaller, and if the rotary potentiometer 1, the trigger 2 and the base 3 are required to be installed and matched, the rotary potentiometer, the trigger 2 and the base 3 are integrally installed in the blower, so that the difficulty is higher; the difficulty of installation is greatly reduced if the rotary potentiometer 1 and base 3 are installed in the blower first and then the trigger 2 is installed. Specifically, after the rotary potentiometer 1 and the base 3 are mounted, the trigger shaft is mounted in place, and then the trigger mounting hole 22 is sleeved on the trigger shaft, and the trigger 2 is pressed downwards until the trigger gear 21 is meshed with the potentiometer gear 11.
In the actual installation process, the operator may cause misalignment of the trigger gear 21 and the potentiometer gear 11 due to misalignment when the trigger 2 is pressed down, that is, one or several teeth on the trigger gear 21 and the potentiometer gear 11 located at the edge cannot be used, which reduces the utilization rate of the potentiometer gear 11.
In order to solve the problem of the misalignment of the trigger gear 21 and the potentiometer gear 11 (or referred to as fool-proofing), a fool-proofing mechanism may be provided. Illustratively, the fool-proof mechanism may be that a positioning protrusion 13 is provided on the rotary potentiometer 1, a stopper 31 is provided on the base 3, and the positioning protrusion 13 abuts on the stopper 31 when the rotary potentiometer 1 is rotated to the set position.
The fool-proof mechanism may also be that a flat plate 23 is used for shielding part of the trigger gear 21 and a limiting plate 14 is used for shielding part of the potentiometer gear 11, and once the potentiometer gear 11 is misplaced during installation, the trigger gear 21 cannot be smoothly buckled with the potentiometer gear 11, so that an operator is reminded of installing errors.
Specifically, the flat plate 23 is arranged on the side surface which is firstly contacted with the rotary potentiometer 1 when being installed on the end of the trigger 2, and the connecting line of the first arc-shaped surface at the outer end of the flat plate 23 and the tooth top surface of the all shielded trigger gear 21 is positioned in the same curved surface; the limiting plate 14 is arranged on the side surface which is firstly contacted with the trigger 2 during installation, and the connecting line of the second arc-shaped surface at the outer end of the limiting plate 14 and the tooth top surface of the all shielded potentiometer gear 11 is arranged in the same curved surface. The assembly fool-proof mechanism and the stopper 31 are respectively located at both sides of the potentiometer mounting hole 12.
The fool-proof mechanism can be arranged on the base 3 and the rotary potentiometer 1, can be arranged on the rotary potentiometer 1 and the trigger 2, and can be arranged between the base 3 and the rotary potentiometer 1 at the same time, and the fool-proof mechanism is arranged between the rotary potentiometer 1 and the trigger 2.
Of course, foolproof mechanisms of other structures are also possible. For example, by providing a projection on one of the rotary potentiometer 1 and the base 3 and providing a recess on the other, the assembly position can be accurately determined, and the assembly dislocation can be avoided.
When in installation, the rotary potentiometer 1 is rotated to a position where the positioning lug 13 is abutted against the stop block 31, and the trigger 2 is pressed from top to bottom; the gears which are blocked on the rotary potentiometer 1 and the trigger 2 cannot be installed, so that the trigger 2 can be accurately installed only by operators aiming at the edges of the flush plate 23 and the limiting plate 14.
When in use, the flat plate 23 is positioned on the bottom surface of the trigger 2, the limiting plate 14 is positioned on the top surface of the rotary potentiometer 1, the two are not interfered with each other, the meshing of all gears on the trigger gear 21 and the potentiometer gear 11 is not influenced, and the utilization rate of the potentiometer gear 11 is improved.
Note that the above is only a preferred embodiment of the present invention and the technical principle applied. It will be understood by those skilled in the art that the present invention is not limited to the particular embodiments described herein, but is capable of various obvious changes, rearrangements and substitutions as will now become apparent to those skilled in the art without departing from the scope of the invention.
