Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, specifically to a high-speed hair dryer with a wireless charging ceramic heating element. Background Technology

[0002] A hair dryer is an electrical device primarily used for quickly drying and styling hair. It works by converting electrical energy into heat through a heating wire, which is then conducted to the walls of the ceramic outer and inner tubes, generating hot air. A fan draws in the air, heats it, and blows it out, achieving rapid drying. A cordless hair dryer, on the other hand, is a portable device that does not rely on a power cord. It is typically powered by a built-in battery (such as a lithium battery) and offers advantages such as portability and flexible operation. It is not restricted by a power cord, making it easy to carry and move, reducing cord tangles and safety hazards, and providing greater convenience and comfort.

[0003] Existing hair dryer heating devices, as shown in Chinese application No. 201620640334.X: Hair Dryer Electric Heating Device, include: an outer tube, hollow in shape and made of ceramic material, having an accommodating space; an inner tube, hollow in shape and made of ceramic material, having a through hole, the inner tube being assembled within the accommodating space; and a heating wire disposed between the inner tube and the outer tube, which generates heat when a power source is applied and conducts the heat to the inner and outer peripheral walls of the inner and outer tubes to improve the thermal efficiency of the hair dryer.

[0004] The existing technology has the following drawbacks: In the hair dryer mentioned above, heating is achieved by heating the ceramic with a heating wire. Due to the high resistance of the heating wire, the efficiency of converting electrical energy into heat energy is limited, resulting in a significant increase in energy consumption, which is not conducive to energy saving and the battery life of wireless portable devices. At the same time, when the heating wire is working at high temperatures, it will radiate a large amount of heat energy, causing strong local heat radiation. In addition, the heating wire is usually fixed with materials such as mica sheets, which will emit fine asbestos fiber particles at high temperatures, which are quite harmful to the human body. Therefore, there is room for improvement. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed wireless charging ceramic heating element hair dryer to solve the technical problems of existing heating wires emitting asbestos fiber particles and emitting significant radiation during the heating process, which is harmful to the human body, and also has high energy consumption, which is not conducive to the battery life of wireless hair dryers.

[0006] To achieve this objective, the present invention adopts the following technical solution: A high-speed wireless charging ceramic heating element hair dryer includes a barrel, a fan, a ceramic body, and a battery. The barrel has an air inlet and an air outlet. The fan, ceramic body, and battery are all housed within the barrel. The fan is driven by a drive assembly to blow air into the barrel through the air inlet. The drive assembly is electrically connected to the battery. The ceramic body is made of conductive ceramic and is electrically connected to the battery. The ceramic body has through holes and is used to heat the air inside the barrel. The air inside the barrel is blown out through the air outlet.

[0007] Optionally, the surface of the ceramic body near the air outlet is configured as a first surface, and the first surface forms a convex arc surface along a first direction.

[0008] Optionally, the surface of the ceramic body near the air inlet is configured as a second surface, and the second surface forms a convex arc surface along the first direction.

[0009] Optionally, the high-speed hair dryer also includes a heat insulation ring for securing the ceramic body to the cylinder.

[0010] Optionally, two sets of the heat insulation rings are provided, and the heat insulation rings are provided on both sides of the ceramic body to clamp and fix the ceramic body.

[0011] Optionally, a limiting seat is provided inside the cylinder, and a groove is provided on the ceramic body, with the limiting seat engaging with the groove.

[0012] Optionally, the inner surface of the end of the cylinder near the air outlet is uniformly coated with a heat-insulating coating.

[0013] Optionally, the through holes are configured in a honeycomb shape.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention uses a thermally conductive ceramic body, which enables the ceramic body itself to generate heat. Compared with a heating wire, it has a higher heating efficiency and consumes less electricity for the same heating effect, thus improving the battery life of the cordless hair dryer. At the same time, compared with a heating wire, it reduces the radiation generated during use, and the ceramic material itself is heat-resistant, eliminating the need for materials such as mica sheets, reducing the release of harmful particles and improving user safety.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] The ceramic heating element high-speed hair dryer provided in this embodiment is applied to a wireless hair dryer. By improving the heating structure of the hair dryer in this embodiment, the wireless hair dryer has lower energy consumption and longer battery life, while reducing radiation and harmful particles from harming the human body during use.

[0024] Please see Figures 1-3The high-speed hair dryer with ceramic heating element provided in this embodiment includes a barrel 10, a fan, a ceramic body 30, and a battery 40. The barrel 10 is provided with an air inlet 50 and an air outlet 60. The fan, ceramic body 30, and battery 40 are all disposed inside the barrel 10. The fan is driven by a drive assembly to blow air into the barrel 10 from the air inlet 50. The drive assembly is electrically connected to the battery 40. The ceramic body 30 is a conductive ceramic and is electrically connected to the battery 40. The ceramic body 30 is provided with a through hole 80. The ceramic body 30 is used to heat the air inside the barrel 10. The air inside the barrel 10 is blown out from the air outlet 60. Specifically, the battery 40 is electrically connected to the drive assembly, which drives the fan to operate, blowing external air into the cylinder 10. The ceramic body 30 is directly electrically connected to the battery 40. Since the ceramic body 30 is a conductive ceramic structure, it has a certain resistance. When energized, the resistance on the ceramic body 30 converts electrical energy into heat energy. When cold air flows through the through-hole 80 of the ceramic body 30, the ceramic body 30 heats the airflow, forming a stable and uniform hot airflow. Compared with traditional metal heating wires, conductive ceramics have higher heat conversion efficiency and faster heating speed, resulting in a faster heating response. It can make the blown air reach the target temperature in a short time, meaning that more effective heat can be generated with the same amount of electricity, reducing total energy consumption. The ceramic material has a fast thermal response and precise temperature control, reducing unnecessary energy consumption and helping to extend the battery life of the wireless hair dryer. Furthermore, the heating of the ceramic body 30 reduces the release of harmful substances such as asbestos fiber particles, ensuring user safety.

[0025] The drive component can be a brushless DC motor or a Hall effect motor. These structures have advantages such as small size, high efficiency, and fast response speed, and are well known to those skilled in the art, so they will not be described in detail in this embodiment. Furthermore, the ceramic body 30 can be made of silicon carbide, silicon nitride ceramics, metal oxide-based ceramics, composite conductive ceramic materials, etc., as the conductive ceramic. It can be manufactured into a heat-generating ceramic product through ceramic powder processing. The resistivity and shape of the product can be processed and produced according to actual needs.

[0026] Furthermore, the surface of the ceramic body 30 near the air outlet 60 is configured as a first surface 90, and the first surface 90 forms a convex arc surface along a first direction. Specifically, the first surface 90 serves as the heating surface of the ceramic body 30 facing the air outlet direction, and its shape is configured as an arc surface structure convex along the first direction. That is, the surface is a convex shape with curvature. Compared with traditional planar or concave heating surfaces, the convex arc surface can effectively expand the heating surface area, while changing the airflow trajectory in the heating zone, thus extending the heating path of the airflow entering the arc surface area and increasing the heat exchange time, thereby improving the sufficiency and uniformity of air heating.

[0027] The first direction refers to the direction along the airflow or the direction consistent with the axis of the cylinder 10. The arc-shaped structure allows the hot air to diffuse more naturally along the air outlet 60 after passing through the ceramic body 30, avoiding the formation of local high temperature concentrations and optimizing the diffusion state of the hot air structurally. At the same time, the arc-shaped surface has higher mechanical strength and thermal stability, which can effectively cope with the thermal expansion and contraction of the ceramic body 30 during rapid heating and cooling, avoid ceramic cracks caused by thermal stress concentration, and improve service life and structural reliability.

[0028] Furthermore, the surface of the ceramic body 30 near the air inlet 50 is designated as a second surface 100, and the second surface 100 forms a convex arc surface along the first direction. Specifically, the second surface 100 is designed as an arc surface, which has higher bending stiffness and can better disperse and bear stress. After being heated at high temperatures, its bending strain and stress are distributed along the arc, reducing local stress concentration, lowering the risk of deformation, reducing material warping, bending and cracking caused by high temperatures, and improving the heat resistance and structural stability of the ceramic body 30. At the same time, it increases the number of through holes 80 per unit volume, thereby increasing the heat exchange area and improving the heating rate.

[0029] Furthermore, the high-speed blower with ceramic heating element also includes a heat insulation ring 110 for fixing the ceramic body 30 inside the cylinder 10. Specifically, the ceramic heating element has a high temperature, and direct contact with the cylinder 10 or other structural components can easily lead to heat loss, affecting the overall energy efficiency and heating efficiency. The heat insulation ring 110 acts as a heat insulation barrier, reducing heat conduction from the ceramic body 30 to the external cylinder 10 or other components, maintaining the concentration of the heating zone, and improving thermal efficiency. At the same time, the heat insulation ring 110 serves as a fixed support, keeping the ceramic position stable and preventing displacement or breakage caused by vibration or thermal expansion and contraction.

[0030] Furthermore, two sets of heat insulation rings 110 are provided, located on both sides of the ceramic body 30, for clamping and fixing the ceramic body 30. Specifically, two sets of heat insulation rings 110 are provided, clamping the two sides of the ceramic body 30 to restrict the conduction and heat dissipation of the high-temperature ceramic to external structures (such as the cylinder 10 or the outer shell), further reducing the heat energy dissipated by the high temperature of the ceramic body 30, and preventing the high temperature of the ceramic body 30 from being transferred to the cylinder 10 or other components through heat conduction; at the same time, it ensures that the ceramic body 30 is stably installed inside the cylinder 10.

[0031] Ceramics expand at high temperatures, and without effective securing measures, the ceramic body 30 is prone to displacement or vibration during vibration or thermal expansion and contraction. Furthermore, a limiting seat 120 is provided inside the cylinder 10, and a groove 20 is provided on the ceramic body 30. The limiting seat 120 engages with the groove 20. This engagement effectively restricts the longitudinal and lateral movement of the ceramic body 30, ensuring it remains in the predetermined position.

[0032] Furthermore, the inner surface of the end of the cylinder 10 near the air outlet 60 is uniformly coated with a heat-insulating coating 130. Specifically, by coating the inner surface of the end of the cylinder 10 near the air outlet 60 with a heat-insulating coating 130, heat can be effectively isolated from conduction and loss to the outside of the cylinder 10 or other parts, maintaining concentrated heat output, enhancing the concentration and convergence of heat in the air outlet 60 area, and improving the drying rate.

[0033] Furthermore, the through holes 80 are configured in a honeycomb shape. Specifically, the honeycomb structure of the through holes 80 increases the surface area of ​​the ceramic body 30 in contact with the air. When heat energy is conducted to the air through the ceramic body 30, the larger the area, the higher the heat transfer efficiency, which accelerates the heating speed of the air and improves the overall drying efficiency.

[0034] In summary, the high-speed hair dryer with ceramic heating element provided in this embodiment has advantages such as reducing hair dryer energy consumption, extending hair dryer battery life, and improving hair dryer safety.

[0035] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
