Problems solved by technology

However, the coil spring structure of the vacuum cleaner cord reel in the prior art has the following disadvantages. When the user pulls out the power cord, the pulling force of the number of turns of the cord reel is proportional to the pulling force. Fast; while the winding wheel is in the process of returning the thread, the initial spring force of the return line is the largest, and the output force of the winding spring gradually decreases as the return line continues, and the vacuum cleaner cannot return the line at a uniform speed and stability in the return line, so that The power cord does not rotate smoothly

Embodiment 1

[0028] image 3 It is a three-dimensional exploded schematic diagram of an auxiliary driving mechanism in the present invention; Figure 4 It is a three-dimensional combined schematic view of the present invention provided with an auxiliary driving mechanism; Figure 5 It is a plan combination schematic view of the present invention provided with an auxiliary driving mechanism. Embodiment 1: Now take a main driving mechanism and an auxiliary driving mechanism arranged horizontally as an example for illustration, and the auxiliary driving mechanism includes a coaxial and horizontally arranged main driving mechanism 10 and a first auxiliary driving mechanism 20, two of which The coil springs in the drive mechanism are connected in series and arranged concentrically. The diameter of the coil spring of the main drive is greater than the diameter of the coil spring in the auxiliary drive mechanism. The outside of the coil spring 12 of the main drive mechanism 10 is clamped on the ...

Embodiment 2

[0029] Image 6 It is a three-dimensional exploded schematic view of the present invention with two auxiliary drive mechanisms; Figure 7 It is a schematic plan view of the present invention with two auxiliary drive mechanisms. Embodiment 2: Now take two auxiliary drive mechanisms arranged horizontally as an example for illustration. The reel includes a main drive mechanism 10, a first auxiliary drive mechanism 20 and a second auxiliary drive mechanism 30 arranged coaxially and horizontally. The coil springs in the mechanism are connected in series and arranged concentrically, the diameter of the coil spring in the main driving mechanism is the largest, the diameter of the coil spring in the second auxiliary driving mechanism is next, and the diameter of the coil spring in the first auxiliary driving mechanism is the smallest, so The reel box includes a main drive mechanism 10, a first auxiliary drive mechanism 20, and a second auxiliary drive mechanism 30 arranged coaxially ...

Abstract

The invention discloses a dust collector reel, which comprises a center shaft, a reeling wheel, a main reeling wheel driving mechanism consisting of a coil spring and a coil spring shell, and an auxiliary driving mechanism coaxial with the driving mechanism, wherein the auxiliary driving mechanism comprises a coil spring, a coil spring shell and a clamping groove, the coil spring of the auxiliary driving mechanism is connected in series with the coil spring of the driving mechanism, and the rotating directions of all the coil springs are consistent. The dust collector reel has the advantages that: two or more coil springs are adopted, and the coil springs rotate when a power wire is pulled out, so the extreme value of the pull-out force is reduced, the pull-out force is uniform and the constant output force is realized.

Description

technical field [0001] The invention relates to a vacuum cleaner; in particular, it relates to a coil spring structure of a cord reel for a vacuum cleaner with uniform tension. Background technique [0002] Generally, a vacuum cleaner is a device that uses a vacuum to generate suction to inhale air, make the air flow through various filters, filter foreign objects in the air, and clean the room. [0003] Generally speaking, a vacuum cleaner mainly includes a suction device and a suction pipeline. The suction device mainly formed by a motor and a fan is arranged in the body. The suction pipeline includes a suction head and a suction pipe. The suction head has a downward opening. The suction port communicates with the air inlet of the fan inside the body through the telescopic pipe and the flexible pipe of the suction pipe. When the vacuum cleaner is running, the motor drives the impeller of the fan to rotate at a high speed, exhausting the air in the vacuum cleaner, forming ...
