Ionic brush and method of use

Abstract

The present application relates to ionic brushes and methods of use. Non-electric hair brushes produce negative ions. The hair brush has more than one component that is coated, infused, or made of a composite material that includes a heat-emitting radioactive mineral that produces negative ions, such as tourmaline crystals / minerals and / or sodium salts. Optionally, the hair brush has multiple openings that facilitate efficient release and distribution of the negative ions to the user's hair during use.

Description

[0001] This application claims the benefit of provisional patent application number 63 / 748,035, filed January 22, 2025, and non-provisional patent application number 19 / 448,764, filed January 14, 2026, which are incorporated herein by reference. Technical Field

[0002] This invention relates to non-electric hair brushes. Specifically, the hair brush generates negative ions to reduce static electricity during brushing, and methods for using such hair brushes. Background Technology

[0003] Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative) attract each other. Due to weak negative bonding, hair naturally loses negative ions through contact and transfers them to objects / materials. This results in hair strands having an excess of positive charge, causing them to repel each other and attract clothing, objects, or particles in the air. This produces the feel and appearance of "curly" or "staticky" hair.

[0004] Tourmaline is a mineral that, when heated, generates an electrical charge that interacts with moisture in the air or on hair, producing negative ions. Tourmaline has been used to coat power hair styling tools, which generate negative ions when electrically heated. Fans can be provided in power hair styling tools to push and distribute negative ions from the tool towards the hair.

[0005] Sodium salts (secondary alkyl sulfonates / esters) are another type of mineral that releases negative ions, similar to tourmaline. Summary of the Invention

[0006] This invention relates to an improved hair brush that generates negative ions. The hair brush is non-electric and generates negative ions when heated by an external source or when interacting with hair (i.e., rubbing). To effectively generate negative ions, the hair brush of this invention has more than one component coated or infused with a thermoradioactive mineral (e.g., tourmaline crystal) or made of a thermoradioactive mineral composite containing tourmaline crystal.

[0007] As a substitute for or supplement to tourmaline crystals, the hair brush of the present invention has more than one component, which is coated or infused with sodium salt or made of a composite material containing sodium salt.

[0008] The hair brush of the present invention may include the following components: a body, a handle, a pad / liner, bristles, and bristle tips. Furthermore, the body of the hair brush may include openings to improve airflow, thereby effectively releasing negative ions from the hair brush components into the hair.

[0009] The hair brush of the present invention advantageously achieves the generation of negative ions, which do not require electricity for effective distribution, thereby reducing static electricity in the hair. Attached Figure Description

[0010] Preferred embodiments of the invention have been selected for illustrative and descriptive purposes and are illustrated in the accompanying drawings (which are not necessarily to scale), forming part of the specification, wherein: Figure 1 This is a perspective view of the hair brush of the present invention.

[0011] Figure 2 This is a rear view of the hair brush of the present invention, showing an opening on the body of the hair brush.

[0012] Figure 3 This is a front view of the paddle-shaped hair brush of the present invention.

[0013] Figure 4 It is along Figure 1 A simplified cross-sectional view of a hair brush (without bristles) in line 4-4. Detailed Implementation

[0014] See the accompanying drawings, in which the same reference numerals in all the drawings indicate the same elements, such as... Figure 1 , 2 Figures 4 and 5 show the hair brush 100 of the present invention. The hair brush 100 includes: a body 1 forming a brush head; a handle 2 attached to the body, which helps a user hold the hair brush 100; a pad / cushion 3 attached to the body 1, which makes the brush head intact; a plurality of bristles 4 mounted or attached to the pad / cushion 3 for brushing and / or distributing hair; and a bristle tip 5 at the distal end of each bristle 4, which contacts the user's hair / scalp.

[0015] One or more of the hairbrush components listed above (i.e., body 1, handle 2, pad / liner 3, bristles 4, and bristle tips 5) are ( wholly or partially) coated with, infused with, or made of a composite material containing a thermally radioactive mineral that generates negative ions, such as tourmaline crystals or tourmaline minerals. Alternatively, one or more of these hairbrush components are coated with, infused with, or made of a composite material containing sodium salts. Furthermore, one or more of these hairbrush components are coated with, infused with, or made of a composite material containing both tourmaline crystals / minerals and sodium salts (in various proportions).

[0016] The hair brush 100 is not electric and does not have independent heating. Negative ions are generated when the hair brush 100 is used with a hair-hairing tool that has heated hair or the hair brush 100 itself, such as a hair dryer or hair iron. Negative ions are also generated when the hair brush 100 is used without an external heat source, due to the friction between the hair brush 100 and the hair during brushing. When using the hair brush 100, the brushing motion generates negative ions, which neutralize the positive charges in the hair, resulting in reduced curl or static electricity.

[0017] The brush body 1 includes multiple openings 6 that allow airflow into and out of a cavity 7 formed between the body 1 and the pad / liner 3. When the brush 100 is used to brush a user's hair, the flexible pad / liner 3 folds / compresses and expels air from the cavity 7 through the openings 6. The airflow exiting the cavity 7 and through the openings 6 carries and distributes negative ions generated by the brush 100 toward the user's hair, resulting in more efficient and effective release and distribution of negative ions. The number (e.g., 2-90+), shape (e.g., geometric shape, random, uniform, or non-uniform), and size (e.g., <1 mm, close to the size of the brush head) of the openings 6 can vary.

[0018] Figure 3 The image shows a hair brush 200 of the present invention, which has a combination with... Figure 1 , 2 It has all the same components and features as the hair brush 100 described in 4, except that the shape of the main body is roughly rectangular rather than elliptical, thus forming a paddle-shaped brush.

[0019] As an alternative or combination, other thermally radioactive minerals besides tourmaline crystals, tourmaline minerals, sodium salts, secondary alkyl sulfonates / esters, etc., can be used.

[0020] The percentages of tourmaline crystals, tourmaline minerals, sodium salts and / or secondary alkyl sulfonates / esters incorporated into the material can vary, and preferably are two percent (2%) for bristle 4, two percent (2%) for bristle tips 5, and 0.5 percent (0.5%) for pads / cushions 3, all with a deviation of + / - 10%.

[0021] Although the invention has been specifically shown and described with reference to exemplary embodiments, those skilled in the art will understand that various changes in form and detail may be made without departing from the spirit and scope of the invention as defined by the appended claims.
