Description

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

  The curling iron is the primary tool for shaping the hair. There are electric curling irons and steam curling irons as regular curling irons. The heating and heating function of the electric curl iron is realized by a resistance wire or other heating element installed inside. The hair bundle is wound around the rod when in use, and the rod is energized and heated at the same time. It diverges outward from the wrapping hair. Conventional curling irons are often used to straighten or curl hair, and curling irons that curl hair are interested in the prior art in curling and styling selection methods. There is very little research on the adjustment of the rod diameter in a curling iron. The rod diameter of the conventional curling iron is fixed, usually 25mm, 32mm, 38mm, and the size of the bowl-shaped wave that is usually curled with the curling iron is fixed, meeting the needs of waves of different sizes I couldn't do it.

  In the prior art, there are the following several technical methods as a structure for changing the pipe diameter.

  In one situation, for example, a diameter-adjustable uniaxial dough transmission roller (Patent Document 1) discloses that at least two trapezoidal limit guide grooves having the same interval angle are provided on the circumferential surface of the main shaft, One end of the limit guide groove communicates with the end of the main shaft provided with an external screw, the other end is closed, slides into the limit guide groove along one side of the external screw, and the quantity is the same as the quantity of the limit guide groove The sleeve is inserted, and the roller sleeve inserted into the limit guide groove of the main shaft can be assembled as a roller cylinder having a circular end surface. This type of adjustable diameter uniaxial dough transmission roller achieves a change in the diameter of the roller cylinder through a plurality of roller sleeves that can be assembled as a circle.

  In another situation, for example, an adjustable pipe clamp (Patent Document 2) discloses an upper pipe clamp and a lower pipe clamp so that the diameter of the upper pipe clamp is smaller than that of the lower pipe clamp. Largely, a sliding groove corresponding to the lower pipe clamp is provided on the upper pipe clamp, and the size of the pipe clamp is changed by controlling how much it slides into the sliding groove of the lower pipe clamp.

  In the above two situations, in the first situation, a roller sleeve having a plurality of diameters is required in use, and at the same time, it is necessary to provide a corresponding limit groove on the main shaft. It is necessary to perform precision processing on each member, and at the same time, if the structural principle is used for a curling iron, it is very inconvenient in terms of complexity and use. The second situation does not apply to curl irons.

  It has become a new challenge in the industry how to provide a diameter adjustable structure in a curling iron and how to provide an adjustable structure. Designing different curly hairstyles according to your will has already become a strong need for many users. Regarding the structure capable of adjusting the diameter and how to provide it, the following several technical solutions have already been submitted in the prior art.

  First type: For example, a curler (Patent Document 3) discloses a hollow porous cylinder whose diameter is fixed, and a semi-cylindrical piece with a plurality of holes attached to the outside of the rod around the axis, and the cylindrical piece. Can rotate together around the axis to increase the rod diameter or rotate inward to decrease the rod diameter.

  Second type: For example, the curler is a steam type color iron disclosed in the curler (Patent Document 4). The rod is a hollow porous cylinder having a fixed diameter. A single porous, expandable and elastic stainless steel shaft is attached to the outside of the rod, and the size of the rod is increased or decreased using the elastic expansion of the elastic stainless steel shaft.

  The third type: a hand-held electric curler (Patent Document 5) discloses that a rod of the curler includes a plurality of elongated rod members, and these members are arranged in a radial direction in the same direction as each other. Axisymmetric rods are formed on the surface. These rod members can move radially inward and outward together to reduce or enlarge the diameter of the rod. Each rod member includes an elongated base material, a row of brush-like comb teeth protruding outward from the radial direction of the base material, a row of holes provided on the base material, and folding or part of the rod members. In order to provide a rug for the base material of the adjacent rod members in the folded state, a side protrusion that extends along one side of the elongated base material is included.

  In the prior art, there is a curl iron of one type of structure, and for example, disclosed in a telescopic curler (Patent Document 6), the rod diameter can be adjusted by fitting a large pipe to a small pipe Satisfy the demand for different waves.

  The structure for changing the diameter of the rod used in the curl iron has the following disadvantages: First, to change the diameter of the rod, it is necessary to rotate the main shaft or the cylinder at the center of the rod. Therefore, the electrical connection of the heater is affected, and the heating effect is deteriorated by affecting the heating, and the energy consumption is high. Second, the diameter of the rod cannot be adjusted smoothly or the curved surface for adjusting the rod is not smooth, so the hair is easily pinched. Third, the installation of the adjustment structure is unreasonable, and it is difficult to easily adjust the rod diameter when perming the hair.

  Therefore, the design of a curling iron having a structure that is excellent in durability and capable of adjusting the size of the diameter is in great demand in the market.
