Head shaking mechanism and device with head shaking mechanism

Abstract

The invention provides a head shaking mechanism and a device with the head shaking mechanism. The head shaking mechanism comprises a power device, a circumference motion mechanism, an engaging mechanism, a first constitutive structure and a second constitutive structure. The power device is provided with a power output end outputting rotating power, the circumference motion mechanism is connectedwith the power output end, the engaging mechanism comprises a first engaging part connected with the circumference motion mechanism and a second engaging part engaged with the first engaging part, thefirst constitutive structure is fixedly connected with the power device and the second engaging part, and the second constitutive structure is fixedly connected with the first engaging part. Due to the fact that the power device drives the circumference motion mechanism to move, reversing is achieved without needing to move to a certain position and stop and then carry out reverse motion, shakingbetween the first constitutive structure and the second constitutive structure is avoided, and in addition, due to the fact that the circumference motion mechanism is engaged with the second constitutive structure for transmission through the engaging structure, a shaking head between the first constitutive structure and the second constitutive structure can smoothly move and is not prone to shaking.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a head shaking mechanism and a device with the shaking head mechanism. Background technique [0002] The existing electric heater oscillating mechanism usually realizes the oscillating head reversing through a crank linkage mechanism or a rack and pinion mechanism. [0003] If a rack and pinion mechanism is used, the synchronous motor drives the rack and pinion to force the head to change direction. Because the rack and pinion mesh with each other, the assembly gap is small, the head is shaken smoothly, and the body shakes small. However, this rack and pinion mechanism requires Stopping the movement first, and then moving in the opposite direction, will cause the whole machine to vibrate and affect the user's use. [0004] If a crank-link mechanism is used, the crank of the crank-link mechanism is always doing circular motion in the same direction, and there is no p...

Problems solved by technology

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect that the shaking head mechanism in the prior art may shake when changing directions or the whole machine shakes when operating the function keys, thereby providing a mechanism that can avoid occurrences when changing directions. Shake at the same time prevent the shaking head mechanism of the whole machine from shaking when operating the function keys and the device with the shaking head mechanism
