Description

A hair iron having a variable diameter structure

Technical field

The present invention relates to the field of household appliances, and more particularly to a hair iron having a variable diameter structure.

Background technique

The hair iron is the main tool for shaping the hair. The commonly used hair irons are electric hair irons and steam hair irons. The heating and heating function of the electric perm is realized by a resistance wire or other heating element installed inside the hair curling device. When used, the hair bundle is wound on the hair roller, and the hair roller is heated by electric heating, and the heat is wound by the inner layer of hair. Distribute outward. Existing hair irons are commonly used to straighten or curl hair. For hair irons that curl hair, the prior art is concerned with the method of hot rolling and qualitative selection, while the existing hair iron is for the reel There are few studies with adjustable diameters. The roll of the existing hair iron is fixed in diameter, commonly used 25mm, 32mm, 38mm, which makes the curling of the hair curled by the conventional hair iron fixed, which can not meet the demand for different size and size .

In the prior art, the structure for changing the diameter of the pipe body has the following technical solutions:

In one case, as disclosed in a diameter-adjustable single-axis cloth transfer stick (patent application number: 201410350805.9), at least two trapezoidal guide limit grooves having the same interval angle are disposed on the circumferential surface of the main shaft, and the guide limit groove is provided. One end of the shaft is connected with the spindle end provided with the external thread, and the other end is closed. The roller sleeve of the same number of guide limit slots is slidably inserted into the limiting slot along the side of the external thread, and is inserted into the spindle guide limit slot. The inner sleeve can be spliced into a roller whose end surface is circular, and the diameter adjustable single-axis cloth conveying roller can realize the replacement of the diameter of the roller through a plurality of roller sleeves which can be spliced into a circle;

Another situation, such as an adjustable size pipe card (authorization bulletin number CN 203836395 U) Disclosed: By setting the upper tube card and the lower tube card, the upper tube card has a larger diameter than the lower tube card, and the upper tube card is provided with a sliding slot corresponding to the lower tube card, and the lower tube card is controlled to slide into the sliding slot. How much to change the size of the pipe card.

In the above two cases, in the first case, it is necessary to customize a plurality of sets of diameter sleeves and to set corresponding limit slots on the main shaft, which requires precision machining of the components in the structure and utilizes the structure. The principle used for a hair iron is cumbersome and extremely inconvenient to use. The second case does not apply to the iron.

What kind of adjustable diameter structure is set in the hair iron, how to set the adjustable structure? It is a new topic in the industry! It is also a strong demand of users to design different types of hot curls according to their own wishes. Regarding the diameter adjustable structure and how to set it, the following technical solutions have been proposed in the prior art:

Large reel diameter, or inward rotation to reduce the diameter of the reel;

The second type, such as a curling iron (patent number Disclosed in US Pat. No. 3,921, 648 A), the hair curler is a steam curling iron whose roll comprises a hollow porous fixed diameter cylinder. The outside of the drum is equipped with a porous, expandable, flexible Stainless steel shaft, which utilizes the elastic expansion of the elastic stainless steel shaft to increase or decrease the size of the reel;

A third type, as disclosed in the hand-held electric curling iron (Lic. No. CN1043606C), the reel of the hair curler comprises a plurality of elongate reel elements which are arranged in the same direction in the radial direction, generally forming Axisymmetric reel. The reel elements can be moved radially inwardly and outwardly together to reduce and enlarge the diameter of the reel, wherein each reel element comprises: an elongated base body, a row projecting radially outward from the base body The brush teeth, a row of holes provided in the base body, and a side protrusion extending along one side of the elongated base body to serve as a base for the base of the adjacent reel member in the collapsed or partially collapsed state.

There is also a structure of a hair iron, such as a retractable curling iron (application number CN 103355924) A) As disclosed, the large tube sleeve is used to meet the requirements of adjustable roll diameter and hot roll.

The structure used to change 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 requires rotation of the main shaft or the cylinder at the center of the reel, and the electrical connection of the heating member is affected, which affects heating and causes heating. The effect is poor, and the energy consumption is high; secondly, the adjustment of the diameter of the reel is not smooth or the curved surface of the reel is not smooth, and the hair is easy to be gripped; thirdly, the adjustment structure is unreasonable, and it is difficult to heat the curled hair. Easily adjust the diameter of the roll.
