Description

Technical Field

[0001] This utility model relates to an improvement of a high-speed hair dryer, particularly a modification of the air duct structure. Background Technology

[0002] Although there are many types of hair dryers on the market, each with its own unique appearance and functions, their basic structure is largely the same. The main components include the housing, handle, motor, fan blades, heating element, air deflector, switch, and power cord. These components work together to complete the various functions of the hair dryer. Modern high-speed hair dryers have the air inlet located on the handle, and the heating element located in the head. Air enters from the handle, is heated, and then blown out as hot air.

[0003] Existing electric heating elements generally include several heating wire supports and heating wires set on the heating wire supports. When hot air passes through the electric heating element, it is heated by the heating wires and finally blown out from the air outlet.

[0004] Our casing is usually made of resin-based material, which has limited heat resistance. It is easy to melt and deform when overheated. The temperature at the heating element can easily exceed the melting point of these resins, creating a huge safety hazard. Utility Model Content

[0005] In order to overcome the shortcomings of current high-speed hair dryers, such as poor heat dissipation of the heating element which easily damages the resin shell, this utility model provides a handheld high-volume high-speed hair dryer.

[0006] The technical solution of this utility model to solve its technical problem is: a handheld high-volume high-speed hair dryer, including a handle and a head, an air inlet at the lower part of the handle, a high-speed fan inside the handle, an air outlet at the front of the head, a detachable air nozzle at the air outlet, a mounting frame inside the head, the mounting frame including a core cylinder and a guide frame in front of the core cylinder, a plurality of heating wire support plates on the core cylinder, and heating wires outside the heating wire support plates; an air outlet grid on the guide frame, and a heat insulation plate mounting part extending from the outer end of the guide frame to the outside of the heating wire, a ceramic heat insulation cylinder mounted on the heat insulation plate mounting part, the ceramic heat insulation cylinder being located outside the heating wire, the ceramic heat insulation cylinder and the core cylinder forming a heating cavity, and a metal reflective layer being provided on the inner side of the ceramic heat insulation cylinder.

[0007] A preferred structure of a heat insulation plate mounting part includes a front end plate and an outer edge plate located outside the front end plate, wherein the front end of the ceramic heat insulation cylinder is attached to the front end plate and the outer side is attached to the inner side of the outer edge plate.

[0008] To facilitate air intake and reduce wind resistance on the fan handle, a semi-circular air inlet is provided on the air inlet end of the ceramic heat insulation cylinder.

[0009] In a preferred embodiment, the metal reflective layer is a silver film.

[0010] A preferred ceramic material is a cordierite ceramic heat insulation cylinder.

[0011] Furthermore, there is also a magnetic ring groove on the outside of the air guide frame, and a permanent magnet ring is provided on the magnetic ring groove. The machine head is provided with a front opening, and a pressure shoulder is provided towards the center of the front opening. When the mounting bracket is installed in the front opening, one side of the permanent magnet ring is pressed by the pressure shoulder; the rear side of the blow nozzle is magnetically attracted to the permanent magnet ring.

[0012] For easy fixation, the permanent magnet ring is provided with an outer ring, and the pressure shoulder presses on the outer ring.

[0013] The thickness of the ceramic heat insulation cylinder is optimized, with the thickness ranging from 1 mm to 4 mm, and the optimal thickness being 2 mm.

[0014] The thickness of the insulation space is limited, and there is an insulation space of more than 5 mm between the outer end of the ceramic insulation cylinder and the inner wall of the machine head housing.

[0015] To enhance sealing, a top ring is provided at the contact point between the outer side of the air guide frame and the housing, and the top ring seals the housing.

[0016] In use, this invention forms a heating chamber between the ceramic insulation cylinder and the core cylinder, with the heating wire inside. Air enters the handle through the air inlet at the bottom of the handle, is transported to the head by a high-speed fan, and then enters the heating chamber. It is heated by the heating wire and flows out through the air outlet grid of the air guide frame. All the air outlet grids form a complete annular air outlet, and the hot air finally enters the air nozzle and flows out.

[0017] The beneficial effects of this invention are as follows: 1. The ceramic heat insulation cylinder has excellent heat insulation performance, effectively preventing the heat generated by the heating wire from diffusing outwards. During the use of the hair dryer, it avoids excessively high temperatures on the outer casing, reducing the risk of burns to the user from contact with the hair dryer casing. This heat insulation protection is particularly effective for prolonged use, ensuring user safety. The ceramic material itself has fire-retardant properties. Even if the heating wire becomes abnormally hot for some reason, the ceramic heat insulation cylinder can still act as an isolation layer, preventing the spread of flames and reducing the possibility of fire, providing users with more reliable safety protection and excellent heat insulation and fire-retardant performance. 2. The metal reflective layer inside the ceramic heat insulation cylinder can reflect the heat generated by the heating wire in a specific direction. In the hair dryer, this reflection allows the heat to be more concentrated towards the air outlet, reducing heat loss. This means more heat can be used to heat the air, improving energy efficiency, allowing the hair dryer to dry hair faster, and also saving electricity. 3. The cordierite ceramic heat insulation cylinder, combined with a silver film, has a dual-mode heat insulation mechanism, reflecting more than 95% of infrared radiation. The ceramic heat insulation cylinder has excellent heat insulation and high temperature resistance, thereby greatly enhancing heating efficiency and safety performance. Attached Figure Description
