Abstract

The invention relates to the field of devices for drying and styling hair. A diffuser cap is intended for use with a hairdryer and provides for even distribution of airflow over the surface of the head. The claimed device comprises two layers of fabric, between which a closed air pocket is formed for a supply of air. The inner layer is provided with hollow plastic fingers having holes and being secured by eyelets, and with ventilation holes. Air from the hairdryer enters the pocket between the layers of fabric, passes through the hollow fingers and exits via the holes, evenly distributing the airflow over the hair. The outer layer of fabric contains a hole for a hairdryer and ventilation holes for the circulation of air. The ventilation holes in the inner and outer layers help to prevent overheating and improve the circulation of air, gently and efficiently drying the hair. The diffuser cap is made of heat-resistant materials, allowing it to be used with hot air from a hairdryer.

[0003] Diffuser cap

[0004] Description

[0005] The invention relates to hair drying and styling devices and is intended for use in conjunction with a hair dryer. The diffuser cap ensures even airflow distribution across the scalp, allowing for more comfortable and effective hair drying. The diffuser cap dries the entire hair at once, a feature that distinguishes it from standard diffusers, which direct the airflow to individual strands. The device comprises two layers of fabric of different diameters, creating a closed air space between them. The inner layer, which contacts the scalp, is equipped with hollow plastic fingers with holes through which air from the hair dryer passes and exits onto the hair, as well as additional holes for ventilation. The outer layer has holes for the hair dryer and ventilation, ensuring optimal airflow for drying hair.

[0006] IPC class

[0007] A45D20 / 12 - Hair drying apparatus.

[0008] Field of technology

[0009] The invention relates to hair drying and styling products, such as hair dryer diffusers. These devices are designed to evenly distribute airflow and improve hair drying, particularly for creating volume or maintaining the natural texture of curls.

[0010] State of the art

[0011] Modern technology offers a variety of diffusers that attach to the hair dryer nozzle and distribute airflow through the holes. However, most of these devices are made of hard plastic and require manual control throughout the drying process. This limits the user's freedom of movement and can cause discomfort during extended hair styling sessions. Existing solutions also aren't always... PCW20 2 4 / 0 0 0 0 1 2

[0012] 4 provide even drying of the hair, which can lead to overheating in certain areas. This device dries the entire hair mass simultaneously, while standard diffusers direct the air flow to individual strands.

[0013] Disclosure of the essence of the invention

[0014] The objective of the present invention is to create a convenient hair drying device that allows for uniform distribution of air flow and frees the user's hands.

[0015] The diffuser cap includes:

[0016] • two layers of fabric between which an air cavity is formed;

[0017] • the inner layer of fabric contains hollow plastic fingers with holes at the ends through which air passes, and ventilation holes to improve air circulation;

[0018] • the specified fingers are secured in the fabric using eyelets;

[0019] • the outer layer of fabric contains holes (two) for inserting a hair dryer and ventilation holes to improve air circulation.

[0020] Air from the hair dryer enters the cavity between two layers of fabric, passes through hollow fingers, and exits through holes, ensuring even drying. Ventilation holes in the outer layer of fabric improve air circulation and prevent overheating, ensuring gentler hair care.

[0027] Implementation of the invention

[0028] To use the diffuser cap, the user places the device on their head, inserts the hair dryer nozzle into the opening in the outer fabric layer, and turns on the hair dryer. Airflow from the hair dryer passes through the cavity between the two layers of fabric, then is directed through the hollow plastic fingers and out through the openings onto the scalp. This ensures even air distribution across the entire hair surface, speeding up the drying process and preventing overheating in certain areas. Vents in the outer and inner fabric layers regulate temperature and remove excess air, ensuring a comfortable drying experience.

Claims

RST / U202 4 / 0 00 0 1 2 6 Invention formula:

1. A hair drying diffuser cap consisting of two layers of fabric, characterized in that: • a closed air cavity is formed between the inner and outer layers of the fabric for air supply; • hollow plastic fingers with holes at the ends for distributing air flow are built into the inner layer; • fingers are secured to the inner layer using eyelets; • the outer layer contains a hole for inserting a hair dryer nozzle and ventilation holes for air circulation, preventing overheating; • Air supplied through the hair dryer is directed between the layers of fabric, enters the hollow fingers and exits through the holes at their ends, ensuring even drying of the hair.

2. A diffuser cap according to paragraph 1, characterized in that the ventilation holes in the outer layer of fabric help improve air circulation and prevent overheating of the scalp and hair.
