Description

Technical Field

[0001] The present invention relates to the technical field of hair-drying equipment, and in particular to a green, low-power-consumption, multifunctional hair-dryer. Background Art

[0002] Traditional hair dryers generally suffer from high energy consumption, single functions, and inefficient thermal management. Their airflow path design is often suboptimal, with a single air intake method, high wind resistance, and high fan load, making them unfavorable for low-power operation. At the same time, poor heat dissipation of internal components (such as batteries) can affect lifespan and safety, and hair dryers typically only have blowing / heating functions and provide no additional value when idle. Furthermore, fixed integrated structures or simple split designs lack an effective function conversion mechanism, making it difficult to meet users' combined needs for portability, versatility, and green energy saving. Therefore, there is an urgent need to develop an energy-saving hair dryer that integrates efficient airflow organization, intelligent thermal management, and multi-functional expansion. Summary of the Invention

[0003] In order to solve the problems existing in the above-mentioned prior art, the present invention provides a green, low-power consumption, multifunctional hair dryer to solve the current technical problems.

[0005] Preferably, the support plates include a plurality of support plates, and the plurality of support plates are fixed in the first conduit.

[0006] Preferably, the first conduit is a stepped conduit, the end of the stepped first conduit with a larger diameter is connected to the second conduit, and the end of the first conduit with a smaller diameter is connected to the fairing.

[0007] Preferably, a second blade is provided in the fairing, and the second blade is relatively rotatably arranged between the first duct and the fairing.

[0008] Preferably, the first conduit is fixed in the main housing via a circular baffle, a handle is connected to the main housing, the cavity behind the baffle in the main housing is the first cavity, and the air inlet hole is connected to the first cavity.

[0009] Preferably, the first cavity and the second cavity are connected to each other, the second cavity is the cavity inside the handle, a battery is arranged in the second cavity, the battery is connected to the heating tube and the fan through a wire, and a pluggable USB interface is provided on the wire. When the handle and the host are separated, a baffle can be used to block the opening at the top of the handle. At this time, power can be supplied to the outside through the USB interface, acting as a power bank.

[0010] Preferably, an air intake grille is provided below the second cavity, and the airflow at the air intake grille flows through the battery and enters the first duct.

[0011] Preferably, a charging interface is provided at the air intake grille, and a charging base is movably connected below the charging interface.

[0012] Preferably, a through hole is provided in the middle of the fairing, and a fairing grid is provided in the through hole.

[0013] Preferably, the heating tube is a single-head mold heating tube.

[0014] The beneficial effects of the present invention are: The present invention provides a green, low-power, multifunctional hair dryer. The core of the hair dryer lies in the innovative stepped duct design, which accelerates airflow, reduces heat loss, and reduces the energy consumption required to maintain the set temperature. The heating adopts a single-head mold heating tube, and its rapid heating and high thermal efficiency characteristics further improve energy efficiency and are more energy-efficient than traditional heating wires. The airflow is optimized by a two-stage blade system: the first-stage blades driven by the fan generate the basic airflow, and the second-stage blades that can rotate relative to each other in the fairing comb the airflow, reduce turbulence, and improve the flow rate, flow rate and uniformity of hot air distribution. A rectifying grille is provided in the through hole in the center of the fairing to further stabilize the airflow output, avoid local overheating, and improve comfort.

[0015] The air duct design cleverly combines heat dissipation and preheating functions: cold air enters the second cavity from the air intake grille at the bottom of the handle, flows through the surface of the battery to cool it, and at the same time the air flow itself is preheated by the battery. The preheated airflow enters the first cavity of the main housing and flows into the main air duct through the air intake holes at the edge of the first duct. Battery preheating significantly increases the initial temperature of the airflow and greatly reduces the energy and time required for the subsequent heater to heat the airflow to the set temperature, which is one of the keys to achieving low power consumption. The heating tube is fixed in the first duct by multiple modular support plates. These support plates form distributed fixing points and heat diffusion channels, which not only ensure the stability of the heating tube, but also prevent local heat accumulation. At the same time, the heating tube is isolated from the hair dryer casing, reducing the risk of high-temperature deformation.

[0016] The handle is designed for exceptional versatility: a battery in the second cavity connects to the heating tube and blower via a cable with a removable USB port. When the handle is separated from the main unit, the upper opening can be sealed with a flap, instantly transforming the blower into a portable power bank, powered by a USB port. A charging port is integrated into the air intake grille at the bottom of the handle, allowing for convenient vertical charging when paired with a removable charging dock.

[0017] The present invention significantly reduces energy consumption through stepped ducts to accelerate airflow, a dual-blade system to optimize flow, battery preheating air intake, high-efficiency single-head heating tubes, and modular thermal management. At the same time, the detachable handle that can be transformed into a power bank and the convenient vertical charging base design greatly expand the functionality and ease of use of the product, achieving a perfect combination of green, low power consumption and multi-functions.

[0021] The present invention provides an environmentally friendly, low-power, multifunctional hair dryer, comprising: a heating tube, the heating tube being fixed to a support plate 2, which is fixed to a first conduit 1; the first conduit 1 being disposed on a second conduit 3; a blower being disposed within the second conduit 3, the blower being connected to a first blade; and a plurality of air intake holes 12 being provided along the edge of the first conduit 1 for air intake.

[0022] The supporting plates 2 include a plurality of supporting plates 2 , which are fixed in the first conduit 1 .

[0023] The first conduit 1 is a stepped conduit, the larger end of the stepped first conduit 1 is connected to the second conduit 3, and the smaller end of the first conduit 1 is connected to the fairing 5, which is a metal cover or a PPS plastic cover.

[0024] A second blade is provided in the fairing 5 , and the second blade is relatively rotatably provided between the first duct 1 and the fairing 5 .

[0025] The first conduit 1 is fixed in the main housing 6 through a circular baffle 8. A handle is connected to the main housing 6. The cavity behind the baffle 8 in the main housing 6 is the first cavity. The air inlet hole 12 is connected to the first cavity. The main housing 6 and the handle housing 9 are both plastic shells.

[0026] The first cavity and the second cavity are connected to each other. The second cavity is the cavity inside the handle. A battery 10 is arranged in the second cavity. The battery 10 is connected to the heating tube and the fan through a wire. A pluggable USB interface is provided on the wire. When the handle and the host 7 are separated, a baffle can be used to block the opening at the top of the handle. At this time, power can be supplied to the outside through the USB interface, acting as a power bank.

[0027] An air intake grille 11 is provided below the second cavity. Airflow at the air intake grille 11 flows through the battery 10 and enters the first duct 1. The air intake grille 11 is a plastic plate with many through holes provided thereon.

[0028] A charging port is provided at the air intake grille 11 , and a charging base is movably connected below the charging port.

[0029] A through hole is provided in the middle of the fairing 5, and a rectifying grid 4 is provided in the through hole. The rectifying grid 4 is an arc-shaped PPS plastic strip, and a plurality of rectifying grids 4 are evenly distributed in the device.

[0030] The heating tube is a single-head mold heating tube.

[0031] The present invention provides an environmentally friendly, low-power, and multifunctional hair dryer. Its core lies in an innovative stepped duct design (the large end is connected to the first duct 1 with a built-in fan and second blades, and the small end is connected to the fairing 5). This structure accelerates airflow, reduces heat loss, and lowers the energy consumption required to maintain the set temperature. Heating is achieved using a single-end mold heating tube, whose rapid heating and high thermal efficiency further improve energy efficiency, making it more energy-efficient than traditional heating wires. The airflow is optimized by a two-stage blade system: the fan-driven first-stage blades generate the base airflow, while the relatively rotatable second-stage blades within the fairing 5 comb the airflow, reducing turbulence and improving the uniformity of flow rate, flow velocity, and hot air distribution. A rectifying grille 4 is provided in the through-hole in the center of the fairing 5 to further stabilize the airflow output, avoid local overheating, and enhance comfort.

[0032] The air duct design cleverly combines heat dissipation and preheating functions: cold air enters the second cavity (with built-in battery 10) from the air intake grille 11 at the bottom of the handle, flows through the surface of the battery 10 to cool it, and at the same time the air flow itself is preheated by the battery 10. The preheated airflow enters the first cavity of the main housing 6 and flows into the main air duct through the air intake holes 12 at the edge of the first duct 1. The preheating of the battery 10 significantly increases the initial temperature of the airflow, greatly reducing the energy and time required for the subsequent heater to heat the airflow to the set temperature, which is one of the keys to achieving low power consumption. The heating tube is fixed in the first duct 1 by a plurality of modular support plates 2. These support plates 2 form distributed fixing points and heat diffusion channels, which not only ensure the stability of the heating tube, but also prevent local heat accumulation. At the same time, the heating tube is isolated from the hair dryer casing, reducing the risk of high-temperature deformation.

[0033] The handle design is highly versatile: the battery 10 in the second cavity connects to the heating tube and blower via a wire with a removable USB port. When the handle is separated from the main unit 7, the upper opening can be sealed with a flap, instantly transforming the blower into a mobile power source, providing power via the USB port. A charging port is integrated into the air intake grille 11 at the bottom of the handle, allowing for convenient vertical charging when paired with a removable charging dock.

[0034] The present invention significantly reduces energy consumption by accelerating airflow through a stepped duct, optimizing flow through a dual-blade system, preheating the air intake through the battery 10, employing a high-efficiency single-head heating tube, and implementing modular thermal management. At the same time, the detachable handle that can be transformed into a power bank and the convenient vertical charging base design greatly expand the functionality and ease of use of the product, achieving a perfect combination of green, low-power consumption, and multi-functions.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
