Nail Grinder

Description

TECHNICAL FIELD

The present disclosure relates to the technical field of personal care appliances, particularly to a nail grinder.

BACKGROUND

Existing nail grinders typically only have basic grinding functions, but they generate a large amount of dust during use. This dust not only affects operational visibility and hygiene of the working environment but may also be inhaled by users, posing potential health risks. Moreover, most existing devices lack effective dust collection and handling mechanisms, allowing dust to easily enter the interior of the device. Long-term accumulation may cause jamming of transmission components, circuit failures, and other issues, thereby affecting the device’s performance, lifespan, and reliability.

On the other hand, existing nail grinders have relatively single functionalities and usually do not integrate additional features such as a nail lamp. Due to the lack of subsequent phototherapy curing steps, users need to prepare multiple separate devices to complete the entire nail care process. This design not only wastes users’ time and space but also reduces operational convenience and efficiency, failing to provide a smoother and more complete nail care experience.

Therefore, existing technologies have obvious shortcomings in dust control, device multifunctionality, and user operational convenience. There is an urgent need for an innovative nail grinder that can address these issues. This nail grinder should effectively collect and handle dust, prevent it from entering the device interior, and integrate multifunctional designs such as additional features like a nail lamp, enabling users to directly complete subsequent nail care steps like phototherapy curing after grinding, thereby improving the device’s overall performance and user experience.

The driving assembly 118, preferably a motor, provides power for the nail grinder 1. Through the transmission connection between the driving shaft 124 and the rotating shaft 125, the driving assembly 118 rotates the driving shaft 124, which in turn drives the rotating shaft 125 and the attached nail grinding rod 121 to spin at high speed. The rotation of the nail grinding rod 121 acts on the nail surface to achieve grinding and shaping functions. This power transmission structure ensures stable and efficient nail grinding operations for the nail grinder 1.

In other embodiments of the present disclosure (not shown), to improve the efficiency of the nail grinder and adapt to different application environments, the driving assembly 118 may be a pneumatic motor, and the driving shaft 124 is replaced with a pneumatic transmission system. Specifically, the pneumatic motor transmits power through an air pressure pump and pneumatic pipelines, with airflow driving the rotation of the nail grinding rod 121 and the fan 119, eliminating reliance on an electric motor and traditional electric driving shafts. Through this replacement, the nail grinder can reduce battery consumption or power demand, making the device suitable for prolonged continuous operation in environments with limited power supply. The pneumatic drive system can make the nail grinder more lightweight, reduce dependence on electricity, and maintain device stability during high-load operation. Additionally, the working principle of the pneumatic motor is smooth, reducing vibration of internal components and helping to extend the device’s service life.

As shown in FIGS. 3 and 6, to enhance the overall structural strength of the housing 100, multiple reinforcing ribs 122 are formed in the installation space 110 through injection molding. These reinforcing ribs 122 strengthen the housing 100, improving its load-bearing capacity and ensuring it is less prone to deformation or damage during use.

Furthermore, referring to FIGS. 5 and 6, in this embodiment, the driving shaft 124 and the rotating shaft 125 are drivingly connected, ensuring the effective transfer of power from the driving assembly 118. The rotating shaft 125 is sleeved onto the driving shaft 124, and when the driving shaft 124 rotates, the rotating shaft 125 synchronously rotates, thereby driving the nail grinding rod 121 to turn. This design allows the driving assembly 118 to efficiently transmit rotational power to the nail grinding rod 121, ensuring smooth and precise nail grinding. The overall design is simple and compact, reducing potential component interference and improving the device’s operational efficiency and service life.

Refer to FIG. 6. In the nail grinding assembly 117, a fan 119 is sleeved on the rotating shaft 125. The rotation of the rotating shaft 125 drives the fan 119 to spin, generating airflow to aid heat dissipation and cleaning. One end of the rotating shaft 125 adjacent to the mounting groove 112 is equipped with a rotating disc 126, which rotates synchronously with the rotating shaft 125. The end of the rotating disc 126 away from the rotating shaft 125 is threadedly connected with a mounting seat 127, enabling the mounting seat 127 to rotate along with the rotating disc 126. This design ensures coordinated movement between the fan 119 and the rotating disc 126, improving heat dissipation efficiency and operational stability.

Refer to FIG. 6. The rotation of the fan 119 not only aids in device cooling to prevent overheating but also propels airflow, effectively clearing dust and debris generated during operation. By integrating the fan 119 with the rotation of the rotating shaft 125, a compact structural design is achieved, reducing redundant components while enhancing overall efficiency. The cooperation between the rotating disc 126 and the mounting seat 127 ensures stable operation of the fan 119 during rotation, maintaining high performance over prolonged use. This design improves the device’s overall performance, ensuring effective heat dissipation and cleaning during extended operation, thereby extending the device’s lifespan.

In other embodiments of the present disclosure (not shown), to optimize the heat dissipation of the nail grinder, the fan 119 may no longer be directly connected through the rotating shaft 125 but instead adopt an independent electric fan design. Specifically, the fan is driven by a separate electric motor, independent of the rotation of the rotating shaft 125. The fan’s electric motor operates independently, enabling higher rotational speeds for stronger airflow and improved heat dissipation. The independently driven fan provides more efficient air circulation, effectively preventing overheating. Compared to traditional fans directly driven by the rotating shaft 125, the independent electric fan offers more flexible speed adjustment and reduces the impact of the grinding process on the fan, thereby enhancing cooling performance and operational stability.

As shown in FIGS. 7 and 8, the mounting seat 127 is provided with a replacement socket 128. Through this socket 128, users can easily remove and replace different types of nail grinding rods 121. Specifically, part of the mounting seat 127 is exposed outside the housing 100, allowing users to conveniently remove and replace nail grinding rods 121 of various specifications to meet different grinding needs. The design of the replacement socket 128 makes the process of changing nail grinding rods 121 simple and quick, enabling users to flexibly select the appropriate rod 121 based on specific usage requirements, thereby achieving precise nail grinding and trimming. This design allows users to effortlessly switch between different nail grinding rods 121 according to personal needs, enhancing the device’s versatility and adaptability. Coarse grinding heads are suitable for large-scale grinding tasks, quickly removing excess nail material, while fine grinding heads can be used for detailed trimming and polishing, ensuring a smooth and glossy nail surface. Through this modular design, the nail grinder 1 not only meets the needs of different users but also significantly improves flexibility and convenience, allowing the device to adapt to various operating scenarios, further enhancing its practicality and efficiency.

Specifically, referring to FIGS. 5 and 6, the rotating shaft 125 is also sleeved with an adsorption sponge 120, located between the fan 119 and the rotating disc 126. The primary function of the adsorption sponge 120 is to effectively capture dust and debris generated during the nail grinding process, maintaining a clean work area. The fan 119 generates airflow through rotation, directing air and debris toward the adsorption sponge 120, which, thanks to its special material and structure, adsorbs and traps these particles, preventing them from dispersing into the air or contaminating the operating environment. The adsorption sponge 120 not only improves the device’s cleaning efficiency but also reduces the impact of dust on user health during operation, particularly in maintaining a tidy work area during prolonged use. By coordinating the adsorption sponge 120 with the fan 119 and rotating disc 126, dust and debris are efficiently captured and managed, ensuring stable device operation and long-term comfort. Additionally, this design enhances the user experience of the nail grinder 1, allowing users to enjoy nail grinding services while avoiding the dust pollution issues common in traditional grinding processes.

In other embodiments of the present disclosure (not shown), to improve dust collection efficiency and facilitate cleaning, the adsorption sponge 120 can be replaced with a washable metal or plastic filter screen. This screen sieves and collects dust and debris through airflow, no longer relying on the adsorption properties of sponge material. The aperture size of the filter screen can be optimized according to the size of the dust, enabling higher collection efficiency. The filter screen not only allows easier cleaning and reuse, reducing the risk of declining adsorption performance after prolonged use, but also provides higher airflow permeability. This ensures unobstructed airflow inside the device, efficient sieving and collection of dust, reduced internal contamination, and more stable, efficient operation of the device.

Referring to FIG. 9, the housing 100 is provided with a stepped groove 130 at one end of the mounting groove 112, and the wind cover 131 is detachably installed through the stepped groove 130. Specifically, the wind cover 131 is equipped with a stepped buckle 132, which can snap into the stepped groove 130 to achieve secure installation of the wind cover 131. This matching design of the stepped buckle and stepped groove allows easy installation and removal of the wind cover 131, facilitating user cleaning, maintenance, or part replacement. Through the snap-fit connection of the stepped buckle 132 and stepped groove 130, the wind cover 131 is firmly fixed to the housing 100, preventing loosening or detachment of the wind cover due to vibration or improper operation during use. At the same time, users can easily remove the wind cover 131 for maintenance or part replacement, simplifying the device upkeep process. This design not only enhances the stability and safety of the device but also improves usability and maintenance convenience, ensuring long-term reliability.

As shown in FIGS. 1 and 6, the housing 100 is equipped with ventilation windows 133 at positions corresponding to the fan 119. The airflow generated by the fan 119 during operation forms an air circulation through the wind cover 131 and ventilation windows 133. This airflow not only aids in cooling the area around the fan 119, preventing device overheating, but also effectively guides the dust and debris generated during nail grinding. Through this air circulation, debris is directed to the adsorption sponge 120, which captures the debris, maintaining a clean operating area and preventing airborne particles that could affect user experience. The coordination between the fan 119 and ventilation windows 133 ensures efficient device heat dissipation, guaranteeing stability and safety during prolonged operation. The synergy between airflow guidance and the adsorption sponge 120 enhances cleaning effectiveness, reduces potential health impacts from dust, and improves device comfort and efficiency. This design makes the nail grinder more efficient and eco-friendly during use while extending its lifespan.

In other embodiments of the present disclosure (not shown), to optimize device heat dissipation and airflow, the wind cover 131 can be replaced with an adjustable airflow fan cover. Specifically, a fan cover with an adjustable switch allows users to modify airflow intensity based on actual needs, thereby optimizing cooling performance and operational stability. This not only improves heat dissipation but also adjusts airflow according to ambient temperature and device load, enhancing efficiency and durability. The adjustable fan cover design offers greater flexibility, ensuring optimal performance across different usage scenarios while preventing overheating and performance degradation.
