Description

Technical Field

[0001] This utility model belongs to the technical field of hair dryer straighteners, and in particular relates to an air duct structure for hair dryer straighteners. Background Technology

[0002] The hair straightener has two interconnected clamp arms that can open or close relative to each other. Each clamp arm has a heating plate and a blower tube on its opposite side. When the hair is placed between the two clamp arms, the clamp arms are closed so that the heating plate contacts the hair. Hot air is blown out through the blower tube to straighten the hair while drying it, thus reducing damage to the hair.

[0003] Existing hair dryer ducts cannot directly blow air onto the heating element; an angled surface or structural bend is required. However, the airflow received by the heating element is significantly reduced, hindering the increase of the hair dryer's power. The air blown from the outlet has low heat and low velocity, resulting in poor hair straightening effect. Therefore, a new air duct structure for hair dryer straighteners is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide an air duct structure for a hair dryer straightener to solve existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an air duct structure for a hair dryer / straightener, comprising an air duct body, an air inlet on one side of the air duct body, a first layer of air ducts inside the air duct body, a heater inside the first layer of air ducts, a second layer of air ducts on the bottom surface of the air duct body, a base plate on the bottom surface of the air duct body, a plurality of air guide channels on the upper surface of the second layer of air ducts, an air outlet on one side of the inner wall of the second layer of air ducts, first mounting holes symmetrically formed on the left side of the upper surface of the air duct body, first connecting holes symmetrically formed on the left side of the upper surface of the base plate, second mounting holes symmetrically formed on the right side of the upper surface of the air duct body, and second connecting holes symmetrically formed on the right side of the upper surface of the base plate.

[0007] Furthermore, a slot is provided on the bottom surface of the air duct body, and an insert is provided on the upper surface of the bottom plate. The shape and size of the slot are adapted to the insert, and the slot and the insert are engaged. The air guide is provided in three sets, which divide the second air duct into four sets of air guide channels. The four sets of air guide channels are connected to the air outlet.

[0008] Furthermore, the shape and size of the first mounting hole are adapted to the first connecting hole, and the shape and size of the second mounting hole are adapted to the second connecting hole. The first mounting hole and the second mounting hole are connected to the first connecting hole and the second connecting hole by bolt threads.

[0009] Furthermore, the first layer of air duct is connected to the second layer of air duct, the air inlet is connected to the first layer of air duct, the heater is horizontally arranged in the first layer of air duct, and the second layer of air duct has a flat structure.

[0010] This utility model has the following beneficial effects:

[0011] This invention features a heater horizontally positioned within the first-layer air duct. The maximum airflow and pressure from the motor directly contact the left-side surface of the heater, facilitating greater power output for the stylist. Simultaneously, the air flows from the left to the right of the heater, thoroughly heating it as it passes over its surface. Entering the second-layer air duct, the flat structure of the second duct, combined with the larger airflow capacity of the first duct, compresses the hot air, increasing its speed and resulting in a higher heat output and faster airflow for easier hair straightening. The heater itself, a conventional design, primarily consists of a heating wire and an insulating board. The heating wire is typically made of nickel-chromium alloy and wound around an insulating mica board. This design utilizes the high electrical resistance of nickel-chromium alloy to generate heat when energized, while the mica board provides excellent insulation and high-temperature resistance.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figure 1 - Figure 5As shown, this utility model is an air duct structure for a hair dryer straightener, including an air duct body 1, an air inlet 102 on one side of the air duct body 1, a first layer air duct 11 inside the air duct body 1, a heater 3 inside the first layer air duct 11, a second layer air duct 12 on the bottom surface of the air duct body 1, a base plate 2 on the bottom surface of the air duct body 1, a plurality of air guides 121 on the upper surface of the second layer air duct 12, an air outlet 122 on one side of the inner wall of the second layer air duct 12, and three sets of air guides 121 dividing the second layer air duct 12 into four sets of air guide channels, which are connected to the air outlet 122.

[0024] Furthermore, the upper surface of the duct body 1 is symmetrically provided with a first mounting hole 101 on the left side, the upper surface of the base plate 2 is symmetrically provided with a first connecting hole 201 on the left side, the upper surface of the duct body 1 is symmetrically provided with a second mounting hole 103 on the right side, the upper surface of the base plate 2 is symmetrically provided with a second connecting hole 202 on the right side, the bottom surface of the duct body 1 is provided with a slot 13, and the upper surface of the base plate 2 is provided with an insert block 21.

[0025] Furthermore, the shape and size of the first mounting hole 101 are adapted to the first connecting hole 201, and the shape and size of the second mounting hole 103 are adapted to the second connecting hole 202.
