Description

Technical Field

[0001] This application relates to the field of combining hair dryers with aromatherapy, and in particular to a hair dryer with aromatherapy function. Background Technology

[0002] Currently, most hair dryers on the market focus on quickly drying hair, with some high-end products adding negative ion technology to reduce static electricity. As users increasingly demand hair care and experiential experiences, some products are beginning to integrate aromatherapy misting functions. By atomizing aromatherapy ingredients (such as essential oils and plant extracts) and applying them to the hair and surrounding environment via airflow, they simultaneously dry, care for, and provide a fragrance experience. This trend is driving hair dryers to evolve from simple drying tools into "multi-functional care + atmosphere creation" devices, satisfying consumers' dual needs for hair care and quality of life.

[0003] However, existing hair dryers with aromatherapy functions still have significant shortcomings in terms of technical implementation, which restrict the user experience and product reliability. Currently, hair dryers with aromatherapy functions typically employ one of two solutions: First, an aromatherapy dripping device is placed directly near the air outlet, relying on airflow to disperse the aromatherapy liquid. This solution is simple in structure, but the aromatherapy components are distributed very unevenly, resulting in low utilization. Furthermore, the direct contact of liquid aromatherapy with the high-temperature airflow can easily lead to excessively strong fragrance or component deterioration due to rapid evaporation. Second, an aromatherapy atomizer is integrated inside the hair dryer, using ultrasound or heating to atomize the aromatherapy liquid and then spray it out with the airflow. While this solution can improve the uniformity of aromatherapy dispersion, it has significant drawbacks. Regarding circuit safety, the power interface lacks separation between high and low voltage circuits. The low-voltage circuit of the aromatherapy atomizer is directly connected to the main circuit (high voltage) of the hair dryer, posing safety hazards such as leakage and short circuits. In terms of atomizer mounting, most use a snap-fit ​​structure, which is not only complex and costly to manufacture, but also has poor sealing at the connection points, easily leading to leakage of aromatherapy liquid and intrusion of dust and impurities, contaminating internal components and shortening the product's lifespan. These issues prevent existing aromatherapy hair dryers from meeting consumer expectations in terms of safety and durability, necessitating technological optimization to achieve a breakthrough. Utility Model Content

[0004] The purpose of this application is to provide a hair dryer with aromatherapy function.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution: a hair dryer with aromatherapy function, including a hair dryer body, a circuit board assembly and an aromatherapy atomizer assembly; the circuit board assembly is installed inside the hair dryer body; the aromatherapy atomizer assembly includes an atomizer and a magnetic fixing structure, the atomizer is detachably fixed inside the hair dryer body by the magnetic fixing structure, and the atomized aromatherapy can be sprayed out with the airflow inside the hair dryer body.

[0006] By adopting the above technical solution, the hair dryer body, circuit board assembly, and aromatherapy atomizer assembly are combined, and the atomizer can be detached and installed using a magnetic fixing structure. This not only simplifies the atomizer replacement process and allows users to switch between different aromatherapy types according to their needs, but also improves the sealing of the connection points through magnetic attraction, effectively reducing aromatherapy liquid leakage and dust and impurities intrusion, lowering the risk of internal component contamination, and extending the product's lifespan. At the same time, the integrated structural design allows the atomized aromatherapy to be sprayed evenly with the airflow of the hair dryer, achieving simultaneous drying, hair care, and fragrance experience, improving ease of use and comfort. The reasonable setting of the circuit board assembly provides a stable power supply for the aromatherapy atomization function, further ensuring the safety and reliability of the device's operation. The overall solution effectively solves the shortcomings of existing aromatherapy hair dryers in terms of fixing methods, sealing, and usage flexibility, meeting consumers' needs for multifunctional, high-quality hair care devices.

[0007] Optionally, the magnetic fixing structure includes a magnet and an iron sheet, wherein the magnet is disposed inside the hair dryer body and the iron sheet is disposed on the outer wall of the atomizer; or the magnet is disposed on the outer wall of the atomizer and the iron sheet is disposed inside the hair dryer body, wherein the magnet and the iron sheet are magnetically attracted to each other.

[0008] By adopting the above technical solution, the magnetic fixing structure achieves a detachable connection between the atomizer and the hair dryer body through the cooperation of magnets and iron sheets. Both setting methods can flexibly adapt to the internal structural layout of the product, ensuring the stability of the atomizer during installation and simplifying the installation and removal operation, making it convenient for users to quickly replace the atomizer. At the same time, compared with the traditional buckle structure, the magnetic connection reduces the mechanical contact gap at the connection point, significantly improving the sealing performance. It can effectively prevent the leakage of aromatherapy liquid and the intrusion of dust, protect the internal components from contamination, extend the service life of the equipment, and the manufacturing process of the magnetic structure is simpler, which helps to reduce manufacturing costs and further enhance the market competitiveness of the product.

[0009] Optionally, the hair dryer body has an internal mounting bracket, a first conductive post on the mounting bracket, and a fastening component on the mounting bracket. The fastening component and the mounting bracket together form a mounting groove adapted to the shape of the atomizer. The atomizer has a second conductive post. When the atomizer is fitted into the mounting groove, the first conductive post and the second conductive post make contact to conduct current.

[0010] By adopting the above technical solution, the mounting bracket and fastening components inside the hair dryer body form a mounting groove that fits the shape of the atomizer, providing precise positioning and a stable mounting foundation for the atomizer, preventing displacement of the atomizer due to vibration during equipment operation. At the same time, the first conductive post on the mounting bracket and the second conductive post of the atomizer achieve docking and conduction through interlocking installation, eliminating the need for additional wiring operations, simplifying the circuit connection process, and ensuring the stability and reliability of current transmission. This not only improves the convenience of atomizer installation but also ensures the stable operation of the aromatherapy atomization function. The overall structural design allows the mechanical fixing of the atomizer and the circuit connection to be completed simultaneously, improving product assembly efficiency and safety of use.

[0011] Optionally, the atomizer includes an aromatherapy body, in which an atomizer contact plate is provided as a carrier for the second conductive post. The aromatherapy body has a receiving cavity, in which a ceramic heating element and absorbent cotton are integrated. The absorbent cotton is fitted around the outer periphery of the ceramic heating element and is in contact with the ceramic heating element. The ceramic heating element is electrically connected to the atomizer contact plate.

[0012] By adopting the above technical solution, the aromatherapy body's receiving cavity in the atomizer integrates a ceramic heating element and absorbent cotton. The absorbent cotton is fitted tightly around the ceramic heating element, continuously providing aromatherapy liquid to the ceramic heating element and ensuring a stable liquid supply during the atomization process. At the same time, the ceramic heating element is electrically connected to the atomizer's contact plate, which serves as the carrier of the second conductive post, efficiently converting electrical energy into heat energy to atomize the aromatherapy liquid. This structural design not only ensures the uniformity and continuity of aromatherapy atomization but also reduces liquid waste and improves aromatherapy utilization through the close cooperation between the absorbent cotton and the ceramic heating element. Furthermore, the integrated layout makes the atomizer structure more compact, adapting to the mounting slot while ensuring efficient atomization.

[0013] Optionally, an aromatherapy internal oil-proof baffle is provided above the absorbent cotton inside the receiving cavity. A soft rubber waterproof ring is provided between the aromatherapy internal oil-proof baffle and the top of the ceramic heating element. The soft rubber waterproof ring is fitted onto the top of the ceramic heating element and is in sealed contact with the aromatherapy internal oil-proof baffle. A soft rubber waterproof pad is provided between the edge of the aromatherapy internal oil-proof baffle and the cavity wall of the receiving cavity. The soft rubber waterproof pad is tightly fitted to both the aromatherapy internal oil-proof baffle and the cavity wall of the receiving cavity.

[0014] By adopting the above technical solution, an internal oil-proof baffle is installed above the absorbent cotton inside the cavity, and a soft rubber waterproof ring is used to achieve a sealed contact between the oil-proof baffle and the top of the ceramic heating element. At the same time, a soft rubber waterproof pad is placed between the edge of the oil-proof baffle and the cavity wall to form a tight fit. This double-sealing structure design can effectively prevent insufficiently atomized aromatherapy liquid from seeping upwards, avoiding leakage of aromatherapy liquid to the outside of the atomizer and contaminating the internal components of the hair dryer. This not only ensures the pure output of aromatherapy ingredients during atomization, but also improves the waterproof performance of the overall structure through the sealing properties of the physical adhesive material, reducing the impact of liquid on the circuit connection parts, and further extending the service life of the atomizer and the whole machine. At the same time, the oil-proof baffle can also play a preliminary filtering role for the atomized aromatherapy droplets, improving the uniformity of aromatherapy output.

[0015] Optionally, the aromatherapy body is provided with an aromatherapy outlet, and an aromatherapy baffle is provided between the aromatherapy outlet and the internal oil-proof baffle of the aromatherapy.

[0016] By adopting the above technical solution, an aroma diffuser baffle is installed between the aroma outlet of the aroma diffuser body and the internal oil-proof baffle. This baffle further guides and homogenizes the aroma droplets after they have been filtered by the oil-proof baffle, preventing the droplets from spraying out in a concentrated manner and causing excessively high local aroma concentration. This allows the atomized aroma components to diffuse more evenly with the airflow, improving comfort when applied to hair or the surrounding environment. At the same time, the aroma diffuser baffle can also block external dust or debris from entering the cavity through the aroma outlet to a certain extent. Together with the oil-proof baffle, it forms multiple layers of protection, further protecting the internal ceramic heating element, absorbent cotton, and other components from contamination, ensuring the long-term stable operation of the atomizer and extending its service life.

[0017] Optionally, the fastening assembly includes a mounting component and a ventilation component. The outer peripheral wall of the mounting component has a plurality of slots evenly distributed circumferentially. The ventilation component is provided with a plurality of pins corresponding to the slots. The pins are inserted into the slots. The ventilation component is detachably mounted on the outer periphery of the mounting component. The ventilation component has a plurality of ventilation holes evenly distributed on it.

[0018] By adopting the above technical solution, the mounting component and the ventilation component in the fastening assembly are detachably connected through the cooperation of slots and pins. This not only facilitates the installation and replacement of the ventilation component, but also ensures the stability and alignment accuracy of the connection between the two by the evenly distributed slots and pins. The evenly distributed ventilation holes on the ventilation component allow the airflow inside the blower body to flow smoothly, providing a good ventilation environment for the atomizer and avoiding the impact of abnormal local temperature and humidity on the aromatherapy atomization effect or the aging of components. At the same time, this structural design takes into account both the fixing function of the fastening assembly and the ventilation requirements, so that the atomizer in the mounting slot can be stably fixed while maintaining effective exchange of airflow with the outside air, further ensuring the stability and reliability of the equipment operation.

[0019] Optionally, the circuit board assembly includes a high-voltage PCB main board, a low-voltage PCB main board, and a transformer. The high-voltage PCB main board is electrically connected to the AC power input terminal, and the low-voltage PCB main board is electrically connected to the high-voltage PCB main board through the transformer. The high-voltage PCB main board integrates high-voltage circuitry, and the low-voltage PCB main board integrates low-voltage circuitry. The low-voltage PCB main board is electrically connected to the first conductive post and can provide a suitable and safe operating voltage for the atomizer.

[0020] By adopting the above technical solution, the circuit board assembly uses separate high-voltage and low-voltage PCB boards, and connects them electrically through a transformer. The high-voltage PCB board is connected to the mains power and integrates high-voltage circuits, while the low-voltage PCB board integrates low-voltage circuits and is connected to the first conductive post to power the atomizer. This structural design achieves complete isolation between high and low voltage through physical separation, fundamentally eliminating safety hazards such as leakage and short circuits caused by direct connection between high and low voltage. At the same time, the transformer converts the mains power into a safe voltage suitable for the atomizer, ensuring electrical safety during atomizer operation. The independent PCB board layout also facilitates circuit integration and maintenance, improves the overall circuit stability, and provides a solid circuit foundation for the safe and reliable realization of aromatherapy atomization function.

[0021] In summary, this application has at least the following beneficial effect: 1. By combining the hair dryer body, circuit board assembly, and aromatherapy atomizer assembly, and utilizing a magnetic fixing structure to achieve detachable installation of the aromatherapy atomizer assembly, this solution not only simplifies the atomizer replacement process and allows users to switch between different aromatherapy types according to their needs, but also improves the sealing of the connection points through magnetic attachment, effectively reducing aromatherapy liquid leakage and dust and impurity intrusion, lowering the risk of internal component contamination, and extending product lifespan. Simultaneously, the integrated structural design allows the atomized aromatherapy to be evenly sprayed with the airflow of the hair dryer, achieving simultaneous drying, hair care, and fragrance experience, enhancing ease of use and comfort. The rationally designed circuit board assembly provides a stable power supply for the aromatherapy atomization function, further ensuring the safety and reliability of the device's operation. This overall solution effectively addresses the shortcomings of existing aromatherapy hair dryers in terms of fixing methods, sealing, and usage flexibility, meeting consumers' demand for multifunctional, high-quality hair care devices.

The circuit board assembly 2 is installed inside the hair dryer body 1, and the aromatherapy atomizer assembly 3 is detachably fixed inside the hair dryer body 1 by a magnetic fixing structure 32. The atomized aromatherapy can be sprayed out with the airflow inside the hair dryer body 1, which achieves the effects of improving safety, sealing and reducing costs. This is because the circuit board assembly 2 can separate strong and weak currents, reducing safety hazards, and the magnetic fixing structure 32 improves sealing and simplifies the production process.

[0027] Specifically, circuit board assembly 2 includes a high-voltage PCB main board, a low-voltage PCB main board, and a transformer. The high-voltage PCB main board is a printed circuit board made of common circuit board materials. It is electrically connected to the AC power input terminal for connection to AC power and integrates high-voltage circuitry, capable of handling higher voltage currents. This high-voltage PCB main board can be replaced by other types of circuit boards with equivalent functionality. The low-voltage PCB main board is also a printed circuit board, made of similar materials to the high-voltage PCB main board. It is electrically connected to the high-voltage PCB main board via the transformer and integrates low-voltage circuitry, providing a suitable and safe operating voltage for the aromatherapy atomizer assembly 3. This low-voltage PCB main board can also be replaced by other circuit boards that perform the same function. The transformer is a 42.4V step-down transformer, which converts high-voltage to low-voltage power to ensure the safe operation of the aromatherapy atomizer assembly 3. Other similar products capable of step-down voltage conversion can also be selected. The high-voltage PCB main board, low-voltage PCB main board, and transformer are connected together by wires to form a complete circuit system, achieving separation of high and low voltage currents and reducing safety hazards.

If the magnet 321 is placed inside the hair dryer body 1, the iron sheet 322 is placed on the outer wall of the atomizer 31, and vice versa. Through the magnetic attraction between the magnet 321 and the iron sheet 322, the aromatherapy atomizer assembly 3 can be detachably fixed inside the hair dryer body 1.

The absorbent cotton 314 is made of highly absorbent cotton material, fitted around and in close contact with the ceramic heating element 313. It absorbs the aromatherapy liquid and transfers it to the ceramic heating element 313 for atomization. Other absorbent materials can also be used for the absorbent cotton 314. The aromatherapy body 311 also has an atomizer contact plate 312 as a carrier for the second conductive post 8. The ceramic heating element 313 is electrically connected to the atomizer contact plate 312. When the aromatherapy atomizer assembly 3 is installed, it connects to the first conductive post 5 in the hair dryer body 1 to conduct current and provide power to the ceramic heating element 313.

[0030] An internal oil-proof baffle 315 is located above the absorbent cotton 314 within the receiving cavity 9.

A soft rubber waterproof ring 316 is positioned between the internal oil-proof baffle 315 and the top of the ceramic heating element 313. Made of soft materials such as rubber, the ring fits onto the top of the ceramic heating element 313 and seals against the internal oil-proof baffle 315, providing waterproofing and sealing to prevent aromatherapy liquid leakage. The soft rubber waterproof ring 316 can also be replaced by other materials with sealing properties. A soft rubber waterproof pad 317 is provided between the edge of the oil-proof baffle 315 inside the aroma diffuser and the cavity wall of the receiving cavity 9. The soft rubber waterproof pad 317 is also made of soft materials such as rubber, and it fits tightly with the oil-proof baffle 315 inside the aroma diffuser and the cavity wall of the receiving cavity 9 respectively, further enhancing the sealing performance and preventing dust and impurities from entering. The soft rubber waterproof pad 317 can also be replaced by other sealing materials.

[0031] The aroma diffuser body 311 is provided with an aroma diffuser outlet 10. An aroma diffuser baffle 318 is provided between the aroma diffuser outlet 10 and the aroma diffuser internal oil-proof baffle 315.

It can adjust the spray direction and speed of the aroma diffuser so that the aroma diffuser is sprayed more evenly with the airflow. The aroma diffuser baffle 318 can also be replaced by other components that can achieve the same function.

[0032] The hair dryer body 1 has a mounting bracket 4 inside, which is usually made of plastic or metal, and is used to support and fix the aromatherapy atomizer assembly 3. The mounting bracket 4 has a first conductive post 5, which is made of metal and is columnar in shape. It is electrically connected to the low-voltage PCB motherboard and can provide a suitable and safe operating voltage for the atomizer 31.

The mounting bracket 4 also has a fastening component 6, which together with the mounting bracket 4 forms a mounting groove 7 that fits the shape of the atomizer 31, and is used to fix the atomizer 31.

[0033] The fastening assembly 6 includes a mounting component 61 and a ventilation component 62. The outer peripheral wall of the mounting component 61 has a plurality of slots 11 evenly distributed circumferentially. Each slot 11 is a rectangular groove for inserting pins 12 of the ventilation component 62. The ventilation component 62 has a plurality of pins 12 corresponding to the slots 11.
