Description

A hair curling rod assembly for a hair dryer Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a curling iron component of a hair dryer. Background Art

[0002] A hair dryer is a stick-shaped appliance with a blowing function. It houses a fan and a heater, which blow air out from the top of the stick. Its functionality is similar to that of a hair dryer, differing in its internal structure and the direction of the airflow. By attaching different components to the top of the stick, a hair dryer can achieve different functions. Therefore, the blowing direction differs from that of a regular hair dryer, making it more suitable for connecting a curling iron component to curl and shape hair. The curling iron assembly of the hair dryer has an overall cylindrical shape, including an air guide bracket and a cylindrical air guide cover mounted on the air guide bracket. A long air outlet hole is provided on the side of the cylindrical air guide cover. The air blown out from the top of the hair dryer enters the curling iron assembly and is blown out from the long air outlet hole. Since the long air outlet hole is located on the side of the curling iron assembly, the air blown out from the hair dryer enters the curling iron assembly and hits the top of the curling iron before gradually dispersing downwards and being blown out from the long air outlet hole. This can easily cause the air outlet at the bottom of the long air outlet to be smaller than the air outlet at the top, affecting the hair-drying and styling effect. Utility Model Content

[0003] The purpose of the utility model is to provide a curling iron assembly of a hair dryer, and in particular to provide a curling iron assembly which can realize uniform air discharge from the upper and lower ends.

[0005] Specifically, the cylindrical air guide cover is composed of a plurality of arc-shaped shells and a connecting top plate. The arc-shaped shells are staggered end to end and arranged in a cylindrical shape and connected to the connecting top plate. The long strip air outlet holes are formed between adjacent arc-shaped shells.

[0006] Specifically, the staggered displacements between the arc-shaped shells arranged end to end include a direction along the tangent of the cylindrical air guide cover and a direction toward the center of the cylindrical air guide cover.

[0007] Specifically, in the staggered displacements between the several arc-shaped shells arranged end to end, the displacement along the tangential direction of the cylindrical air guide cover body gradually decreases from the bottom end to the top end of the cylindrical air guide cover body, and the displacement toward the center of the cylindrical air guide cover body remains unchanged from the bottom end to the top end of the cylindrical air guide cover body.

[0008] Specifically, a number of supporting ribs are arranged at intervals between adjacent arc-shaped shells.

[0009] Specifically, a connecting buckle that can be connected to the air outlet of the blower rod is provided at the bottom of the air guide bracket, and a plug-in component is provided at the bottom of the cylindrical air guide cover to cooperate with the air guide bracket; a sealing top cover is provided at the top of the cylindrical air guide cover.

[0016] Example 1, referring to Figures 1-5, a curling iron assembly of a hair dryer includes an air guide bracket 1 and a cylindrical air guide cover 2, the cylindrical air guide cover 2 is provided with a plurality of elongated air outlet holes 3 in an equidistant circular array, the width of the elongated air outlet holes 3 gradually decreases from the bottom end to the top end of the cylindrical air guide cover 2, the cylindrical air guide cover 2 is mounted on the air guide bracket 1, and an air outlet channel 4 connected to the elongated air outlet holes 3 is formed between the air guide bracket 1 and the inner wall of the cylindrical air guide cover 2, and the width of the air outlet channel 4 remains unchanged from the bottom end to the top end of the cylindrical air guide cover 2.

[0017] In this embodiment, a cylindrical air guide hood 2 is mounted on an air guide bracket 1 to form a curling iron assembly and is mounted at the air outlet at the top of the hair dryer. Air blown from the hair dryer enters the curling iron assembly, strikes the top of the curling iron assembly, and then gradually flows downward through an air outlet duct 4 formed between the air guide bracket 1 and the cylindrical air guide hood 2 before being blown out through the elongated air outlet 3. The width of the elongated air outlet 3 gradually decreases from the bottom end to the top end of the cylindrical air guide hood 2, while the width of the air outlet duct 4 remains unchanged. During the blowing process, the pressure difference between the inside and outside of the cylindrical air guide hood 2 tends to be higher at the top and lower at the bottom end. Under the premise of the same pressure difference, the larger the width of the elongated air outlet 3, the greater the air volume. Therefore, the change in the width of the elongated air outlet 3 adapts to the change in pressure difference and improves the uniformity of the air volume. The size of the air outlet duct 4 determines the concentration of the air blown out of the elongated air outlet 3. The consistency of the width of the air outlet duct 4 effectively ensures the consistency of the concentration of the air blown out of the elongated air outlet 3. It should be noted that the bottom of the air guide bracket 1 is provided with a connecting buckle 11 that can be connected to the air outlet of the hair dryer, and the bottom of the cylindrical air guide cover 2 is provided with a plug-in component 21 that cooperates with the air guide bracket 1; the top of the cylindrical air guide cover 2 is provided with a sealing top cover 5.

[0018] Among them, the cylindrical air guide cover 2 is composed of a plurality of arc-shaped shells 22 and a connecting top plate 23, and the plurality of arc-shaped shells 22 are staggered end to end to form a cylindrical shape and are connected to the connecting top plate 23, and the long strip air outlet 3 is formed between adjacent arc-shaped shells 22; specifically, the staggered displacement between the plurality of arc-shaped shells 22 staggered end to end includes the staggered displacement along the tangential direction of the cylindrical air guide cover 2 and the direction toward the center of the cylindrical air guide cover 2; more specifically, in the staggered displacement between the plurality of arc-shaped shells 22 staggered end to end, the displacement along the tangential direction of the cylindrical air guide cover 2 gradually decreases from the bottom end to the top end of the cylindrical air guide cover 2, and the displacement toward the center of the cylindrical air guide cover 2 remains unchanged from the bottom end to the top end of the cylindrical air guide cover 2. In the current conventional curling iron assembly, the staggered displacement between adjacent arc-shaped shells 22 is generally in the direction toward the center of the cylindrical air guide cover 2, thereby forming a long strip air outlet hole 3. The displacement in this direction also corresponds to the width of the air outlet channel 4 formed between the air guide bracket 1 and the cylindrical air guide cover 2. Therefore, it is not suitable to adjust the width of the long strip air outlet hole 3 in this direction. On this basis, the utility model adds a displacement along the tangential direction of the cylindrical air guide cover 2, and adjusts the width of the long strip air outlet hole 3 by adjusting this displacement, thereby effectively improving the uniformity of the air outlet volume; at the same time, it can ensure the consistency of the air outlet concentration.

[0019] Preferably, a plurality of support ribs 24 are provided between adjacent arc-shaped shells 22. The support ribs 24 provided between the arc-shaped shells 22 can improve the stability of the connection between the arc-shaped shells 22 and prevent the long strip air outlet holes 3 formed between the arc-shaped shells 22 from deforming during air discharge, resulting in unstable air flow.

[0020] Of course, the above are only preferred implementation methods of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes based on the principles of the present invention should be included in the scope of protection of the present invention.
