Perming device with diameter variable structure

Abstract

The invention discloses a perming device with a diameter variable structure. The perming device comprises a perming assembly and a handle. The perming assembly comprises a perming cylinder, two fixing bases and two rotating pieces. The handle is connected with the perming assembly in the mode that clamping grooves are fixedly connected with the fixing bases in a clamped mode. The perming cylinder comprises a fixed perming cylinder component, a movable perming cylinder component, a middle shaft and two auxiliary perming cylinder components. The fixed perming cylinder component is arranged at the lower portion of the perming cylinder in the radial direction. The movable perming cylinder component is arranged at the upper portion of the perming cylinder in the radial direction. The two auxiliary perming cylinder components are oppositely arranged with the middle shaft as a symmetry axis. The movable perming cylinder component and the two auxiliary perming cylinder components penetrate through the fixing bases and are rotatably connected with the rotating pieces. Rotary knobs are embedded in the positions, corresponding to the clamping grooves, of the outer end of the handle. The rotary knobs are in mortise and tenon connection with the rotating piece at the outer end of the handle. The rotary knobs are twisted, the rotating pieces drive the movable perming cylinder component and the two auxiliary perming cylinder components to move, and the diameter of the perming cylinder is adjusted. The perming device is exquisite and ingenious in structure, convenient to use and capable of perming hair rollers with the different sizes ranging from 25 mm to 45 mm.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a hair iron with a variable diameter structure. Background technique [0002] Hair iron is the main tool that hair shaping is carried out, and commonly used hair iron has electric hair iron and steam hair iron. The heating and heating function of the electric hair iron is realized by the resistance wire or other heating elements installed inside it. When using it, the hair bundle is wound on the hair curler, and the hair curler is energized and heated at the same time. The heat is generated by the hair wound on the inner layer. Radiate outward. Existing hair irons are often used to straighten or curl hair. For hair irons that curl hair, what the prior art cares about is the method of its curling and qualitative selection. There are very few studies on adjustable diameter. The diameter of the reel of the existing hair iron is fixed, and the commonly used ones are 25mm, 32mm,...

Problems solved by technology

[0014] The structure of changing the diameter of the reel used in the above-mentioned hair iron has the following disadvantages: First, the change of the diameter of the reel needs to rotate the main shaft or the cylinder in the center of the reel, and the electrical connection of the heating element is affected, which affects the heating and causes heating. The effect is poor, and the energy consumption is high; second, the adjustment of the diameter of the reel is not smooth or the surface of the adjustment reel is not smooth, and it is easy to clamp the hair; third, the adjustment structure is not reasonable, and it is difficult to curl the hair. Easily adjust the diameter of the reel
