Description

Technical Field

[0001] This utility model relates to the technical field of hair dryers, and in particular to a wind guide cover and hair dryer with temperature control function. Background Technology

[0002] A hair dryer consists of a set of heating elements and a high-speed fan. When powered on, the heating elements generate heat, and the air blown by the fan passes through the heating elements, turning into hot air. If only the fan rotates but the heating elements don't heat up, then only air is blown out without heat. Current hair dryers suffer from two technical problems: turbulent airflow leading to heat damage: traditional hair dryers have disordered airflow, resulting in localized high temperatures and causing heat damage to the hair cuticles; and a bottleneck in drying efficiency: single-stage airflow leads to uneven airflow coverage. Utility Model Content

Detailed Implementation

[0017] The utility model objective of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments cannot be described one by one here, but the implementation of this utility model is not limited to the following embodiments.

[0018] like Figures 1-4 As shown, the hair dryer includes an air guide cover 1, a blower body 2, and a handle 3. The blower body 2 includes a housing 201, an air outlet cover 202, a filter cover 203, six heating air guide plates 204, a motor bracket 208, a drive motor 205, and a fan blade 206. The housing 201 and the handle 3 are rotatably connected via a bevel fitting structure. The air outlet end of the blower body 2 is connected to the air guide cover 1. The right end of the air guide cover 1 is fitted into the air outlet end of the housing 201. The air outlet cover 202 is installed at the air outlet end of the housing 201, and the filter cover 203 is installed at the air inlet end of the housing 201. The air outlet cover 202, the housing 201, and the filter cover 203 form an air-driving chamber. The drive motor 205 is installed in the air-driving chamber via the motor bracket 208. The shaft of the drive motor 205 is connected to the fan blade 206, and the fan blade 206 is located to the right of the drive motor 205. Six heating air guide plates 204 are installed inside the air drive compartment and located to the left of the drive motor 205.

[0019] The function of the air guide shroud 1 is to eliminate turbulence, stratify the airflow, and buffer the temperature of the stratified airflow. The blower body 2 converts electrical energy into wind energy and blows the air out in a directional direction. The handle 3, under external force, can be rotated parallel to the blower body 2, thus achieving a folding effect for the hair dryer, making it easy to carry. It also includes a heating switch 301 and a wind speed adjustment switch 302. The wind speed adjustment switch 302 is used to adjust the wind speed and is connected to the drive motor. The heating switch 301 is used to heat or stop the heating air guide plates 204, and is connected to the six heating air guide plates 204. The main function of the air guide shell 11 is to eliminate turbulence, stratify the airflow, and buffer the temperature of the stratified airflow. The outer shell 201 is used to install and fix various components and guide the airflow. The air outlet shroud 202 is used to prevent the user from contacting the heating guide plates 204, avoiding injury during use. The filter shroud 203 filters the air drawn into the outer shell 201, preventing hair from entering the outer shell 201 and causing danger. Heating wires are provided on the heating guide plate 204 to guide and heat the airflow generated by the fan blades 206. The motor bracket 208 is used to fix the drive motor 205 to the center of the housing 201. The drive motor 205 converts electrical energy into mechanical energy, driving the fan blades 206 to rotate. The fan blades 206 convert mechanical energy into wind energy.

[0020] like Figures 5-8 As shown, the specific structure of the inclined surface mating structure is as follows: The bottom of the outer shell 201 has a first inclined surface with an inclination angle of 45°. A rotation limiting groove 207 is located at the center of the first inclined surface, enabling automatic positioning. The top of the handle 3 has a second inclined surface with an inclination angle of 135°. A rotating boss 303 is located at the center of the second inclined surface, embedded in the rotation limiting groove 207, and rotating relative to the rotation limiting groove 207. The mating of the rotating boss 303 and the rotation limiting groove 207 enables limited-angle rotation and automatic angle positioning. The structures of the rotating boss 303 and the rotation limiting groove 207 are existing technologies and will not be described in detail. With the first and second inclined surfaces mating, in the folded state, the handle 3 and the axis of the outer shell 201 are parallel to each other; in the use state, the axis of the handle 3 and the axis of the outer shell 201 are perpendicular to each other.

[0021] like Figures 9-11As shown, the temperature-controlled air guide shroud includes an air guide shell 11 and a back shell 12. The right end of the air guide shell 11 is connected to the left end of the back shell 12, and the right end of the back shell 12 is engaged with the air outlet end of the outer shell 201. The air guide shell 11 includes a housing 117, ten first outer periphery-facing inward air guide pipes 111, ten second outer periphery-facing inward air guide pipes 112, five center-facing inward air guide pipes 115, and five center-facing outward air guide pipes 116. The housing 117 is circular, and a first air outlet ring 113 and a second air outlet ring 114 are provided on the left side of the housing 117. The first air outlet ring 113 is located on the outer periphery of the second air outlet ring 114, and both the first air outlet ring 113 and the second air outlet ring 114 are composed of multiple air outlet holes. The ten first outer periphery-facing inward air guide pipes 111 are arranged circumferentially to form the first air guide ring. The ten second outer periphery-facing inward air guide pipes 112 are arranged circumferentially to form the second air guide ring. Ten first outer perimeter inward-facing air guide ducts 111 and ten second outer perimeter inward-facing air guide ducts 112 are each provided with obliquely cut air outlets facing the center of the housing 117. The first air guide ring is located on the outer periphery of the second air guide ring. The circumferential position of each second outer perimeter inward-facing air guide duct 112 is aligned with the gap between two adjacent second outer perimeter inward-facing air guide ducts 112, and the radial projection of each second outer perimeter inward-facing air guide duct 112 is projected onto the gap. Both the first air guide ring and the second air guide ring are located within the first air outlet ring 113. Five center-facing inward-facing air guide ducts 115 are each provided with obliquely cut air outlets facing the center of the housing 117; five center-facing outward-facing air guide ducts 116 are each provided with obliquely cut air outlets facing the outer periphery of the housing 117. The five center-facing inward-facing air guide ducts 115 and the five center-facing outward-facing air guide ducts 116 are arranged alternately in a circumferential direction to form a third air guide ring. The center-facing inward-facing air guide ducts 115 face the center of the housing 117, and the center-facing outward-facing air guide ducts 116 are arranged facing the first outer perimeter inward-facing air guide ducts 111. The third air guide ring is located on the second air outlet ring 114.

[0022] The air guide shell 11 diverts and disperses the airflow. The back shell 12 is used to mount and fix the air guide shell 11 and guide the airflow onto it. The shell 117 is used to set the positions of the first air guide ring, the second air guide ring, the third air guide ring, the first air outlet ring 113, and the second air outlet ring 114. The first air outlet ring 113 acts as an outer directional jet curtain, covering the output areas of the first and second air guide rings. The second air outlet ring 114 is used for inner layer precise temperature control jetting, with high-temperature airflow (80℃) precisely acting on the hair roots. The first air guide ring, composed of the first outer inward air guide duct 111, is used to construct the basic flow guide layer, reduce the tangential component, and enhance centripetal flow. The second air guide ring, composed of the second outer inward air guide duct 112, is used for staggered flow replenishment and turbulence suppression. The third air guide ring is used to buffer the thermal gradient at the junction of the first and second air outlet rings. The center inward air guide duct 115 is used to focus the high-temperature core airflow. The central outward-facing air duct 116 is used for the diffusion of high-temperature airflow at the center, realizing the exchange of cold and heat.

[0023] The working process of the temperature-controlled air guide cover and hair dryer: Holding the handle 3 and rotating it outwards by 90° causes the rotating boss 303 to slide within the limiting groove, allowing the first and second inclined surfaces to rotate relative to each other, thus switching the outer shell 201 and handle 3 from an axially parallel state to an axially perpendicular state. The hair dryer is turned on via the heating switch 301, and the wind speed and temperature are adjusted via the wind speed adjustment switch 302. External air is filtered by the filter cover 203 and enters the outer shell 201. The drive motor 205 drives the fan blades 206 to rotate, and the fan blades 206 create a high-speed airflow. This high-speed airflow is divided and heated by the guide plate, forming multiple streams of hot air. The hot airflow located at the center of the outer shell 201 (approximately 80°C) is hotter than the surrounding hot airflow (approximately 50°C) and enters the air guide shell 11 under the guidance of the back shell 12. The first guide ring provides basic airflow guidance, and the second guide ring supplements the hot airflow, enhancing the airflow of the outer directional spray curtain of the first air outlet ring 113 and protecting the hair from overheating. The third guide ring forms a game-like mixed hot airflow, while the second air outlet ring 114 provides high-speed laminar flow, breaking through the wet hair's water film. The third guide ring, forming a game-like mixed hot airflow at the junction of the first and second air outlet rings 113 and 114, acts as a thermal gradient buffer. After drying the hair, the handle 3 is rotated inwards by 90°, causing the rotating boss 303 to slide within the limiting groove, allowing the first and second inclined surfaces to rotate relative to each other. This switches the outer casing 201 and handle 3 from an axially perpendicular state to an axially parallel state, completing the folding state of the hair dryer.

[0024] Advantages of air guide covers and hair dryers with temperature control: 1. Precise temperature control: The water film is broken through at the center at 80℃ + the outer layer is protected against scalding at 50℃ + the 60-65℃ gradient buffer achieves heat protection for the hair roots and protection for the hair ends.

[0025] 2. Airflow stability: Three-ring flow guide + staggered flow replenishment design, turbulence suppression rate >90%.

[0026] 3. Foldable portability: The inclined hinge automatically positions itself at 90°, reducing the folded volume by 50%.

[0027] The above-described specific embodiments are preferred embodiments of this utility model and are not intended to limit this utility model. Any other changes or equivalent substitutions made without departing from the technical solution of this utility model are included within the protection scope of this utility model.
