This application is a non-provisional application that claims priority under 35U.S.C. § 119 to China application number CN202311593627.8, filing date Nov. 24, 2023, and China application number CN202323144534.5, filing date Nov. 21, 2023, wherein the entire content of which is expressly incorporated herein by reference.
The present invention relates to nail clipper, and more particularly to an electric automatic nail clipper.
With the advancement of technology and the improvement of people's living standards, electric nail clippers have begun to enter the public's field of vision and have begun to gradually replace traditional nail clippers.
A conventional nail clipper has an open structure at the cutter head. If an infant touches the cutter head with his lips or tongue, there is a risk that it is easy for the infant to touch the blind spot of the cutter head to cause damage to the lips or tongue.
A conventional electric nail clipper usually uses a fixed rotation speed and the rotation speed is more than 300 rpm. Before this application solution, there was no research on the relationship between the rotation speed of the cutter head and the experience in the current technology. In addition, due to the different user's nails, different hardnesses and a fixed rotation speed will result in poor trimming results. Sometimes, if the hardness of the user's nails is low, too high a speed of the cutter head may lead to over-cutting of the nails. If the user's nails have a high hardness, too low a speed of the cutter head may cause the problem of slow and unable to cut, that is, too high a cutter head speed or too low a cutter head speed will greatly affect the user experience. Therefore, there is a need to develop an electric nail clipper that can automatically adjust the rotation speed of the cutter head.
When the conventional nail clipper is operating, debris build up will take place within the cutter head to cause the cutter head of the conventional nail clipper become clogged with the debris, the clogged cutter head may cause the nail clipper to vibrate excessively or operate noisily, reducing the overall user experience. Unfortunately, the design of conventional nail clippers does not allow the cutter blade to be exposed, preventing the user from easily accessing or cleaning the clogged cutter head. As a result, maintenance becomes difficult, and the tool's performance and longevity are compromised.
The invention is advantageous in that it provides an electric nail clipper comprises an electric nail clipper body. The electric nail clipper body is provided with a cutter slot. The electric nail clipper body is provided with a protruding structure corresponding to the cutter slot and the protruding structure is protruded from a plane where the cutter slot is located for achieving protection through spatial obstruction, the protruding structure is located adjacent to the cutter slot.
Preferably, the protruding structure is a columnar protruding structure or a plate-shaped protruding structure that is protruded from the plane where the cutter slot is located.
Preferably, at least one protruding structure is provided, and the protruding structure is correspondingly provided on at least one edge of the cutter slot.
Preferably, there is one protruding structure, and the plate-shaped protruding structure is a transparent or translucent structure that can be penetrated by sight.
Preferably, there are multiple protruding structures, and each of the plate-shaped protruding structure has a transparent structure through which a line of sight can pass.
Preferably, the protruding structure is arranged along a length direction of the incision groove, so that the nail surface is aligned with the protruding structure when approaching the cutter slot.
Preferably, the electric nail clipper body is an L-shaped structure as a whole, the cutter slot is located on one side of the concave side of the L-shaped structure, and the protruding structure is located on the top corresponding to the side and is protruded from the side, so that the protruding structure is aligned with another side of the L-shaped structure, and a finger entry and exit space is formed between the protruding structure and the another side.
Preferably, side blocking walls are respectively provided on the finger entry and exit spaces at both ends of the cutter slot.
Preferably, the edges of the side blocking walls are respectively connected to both sides of the concave side of the L-shaped structure and the protruding structure, and the free side of the side blocking walls forms an indention toward the direction of the blade.
The electric nail clipper of the present invention is provided with the protruding structure adjacent to the cutter slot. This protruding structure will not prevent the nails from contacting the cutter blade in the cutter slot, but can prevent the lips or tongue from easily touching the cutter blade in the cutter slot. The cutter head prevents safety hazards from occurring.
The protruding structure of the present invention will not affect the line of sight. When trimming nails, the trimming condition of the nails can be observed without affecting the trimming effect.
Another purpose of the present invention is to overcome the above technical deficiencies and provide an electric nail clipper and its control method and control system to solve the problems existing in the conventional technology.

S100. After a motor of the electric nail clipper is started, control a cutter blade of the electric nail clipper to run according to a first preset speed. The first preset speed is within a preset speed range. The upper limit of the preset speed range is 210 revolutions per minute, and the lower limit of the preset speed range is 110 revolutions per minute.
Specifically, the step for obtaining the preset speed interval is: Collet the comfort scores of a preset number of users using the electric nail clipper in different cutter blade speed ranges, and calculate the average of the comfort scores in different speed ranges to obtain the speed range in which the mean comfort score is higher than a preset score. This speed range is used as the preset speed range.
Specifically, the lowest value of the comfort score is 0 points, the highest value of the comfort score is 10 points, and the preset score is 9 points.
S200: Obtain the operating status data of the motor when the user uses the electric nail clipper to trim a nail.
Specifically, the operating status data of the motor comprises an operating current of the motor, and/or an operating voltage of the motor.
Preferably, the operating current of the motor can be sampled through a sampling resistor, and/or the operating voltage of the motor can be sampled through a sampling resistor, and the sampled values of the operating current of the motor and/or the operating voltage of the motor can be measured. Subsequent judgment to determine the user's nail hardness.
What needs to be noted here is that before step S110, the method comprises a step of presetting a first preset threshold, a second preset threshold, a third preset threshold, a fourth preset threshold, a second preset rotation speed, a third preset rotation speed and a first preset rotation speed in a control module. The first preset threshold is greater than the second preset threshold, the third preset threshold is greater than the fourth preset threshold, the second preset rotation speed is greater than the first preset rotation speed, the first preset rotation speed is greater than the third preset rotation speed.
It can be understood that the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold can be specifically set according to the requirements of the actual circuit and the motor parameters. The present invention does not apply to the first preset threshold, the second preset threshold, the third preset threshold, and the fourth preset threshold have specific limits. When different users use electric nail clippers, due to the different hardness of the user's nails, the pressure applied to the cutter blade is usually different, as a result, the operating status data of the motor are different. The higher the hardness of the nail, the greater the operating resistance of the cutter blade, and the greater the current required to maintain the current operating speed of the cutter blade. Therefore, the operating current or operating voltage of the motor will change. When the nail hardness is lower, that is, when the operating current and/or operating voltage data of the motor is small, a lower blade speed is used to avoid over-trimming of soft nails; when the nail hardness is high, that is, when the operating current and/or operating voltage data of the motor is larger, a higher cutter blade speed is used to ensure the trimming effect of hard nail. Therefore, in the setting principles of the first preset threshold, the second preset threshold, the third preset threshold, the fourth preset threshold, the second preset rotation speed, the third preset rotation speed, and the first preset rotation speed, it must be satisfied that the first preset threshold is greater than the second preset threshold, the third preset threshold is greater than the fourth preset threshold, the second preset rotation speed is greater than the first preset rotation speed, and the first preset rotation speed is greater than the third preset rotation speed.
It should be noted here that the second preset rotation speed is preferably 210 rpm, the first preset rotation speed is preferably 160 rpm, and the third preset rotation speed is preferably 110 rpm. The second preset rotation speed is preferably 210 rpm, the first preset rotation speed is preferably 160 rpm, and the third preset rotation speed is preferably 110 rpm. This is obtained by those skilled in the invention through a large number of experiments, by collecting the comfort scores of a preset number of people using different cutter blade speed ranges of the electric nail clipper, the lowest score value is 0 point, the highest score value is 10 points, the preset number is preferably 10, and calculate the mean value of the comfort scores in different speed ranges, and obtain the speed range in which the mean comfort score is higher than the preset score. The preset score is 9 points. The speed in this speed range is 110 to 210 revolutions per minute, that is, the speed range is 110 revolutions per minute to 210 revolutions per minute, and the maximum value of this speed range is used as the second preset speed, that is, the second preset speed is 210 revolutions per minute, and the minimum value of this speed range is used as the third preset speed, that is, the third preset rotation speed is 110 rpm, and the middle value of the rotation speed range is used as the first preset rotation speed, that is, the first preset rotation speed is 160 rpm.
Understandably, please continue to refer to
The rotation speed range for the best user experience is 110 revolutions per minute to 210 revolutions per minute, that is, the rotation speed range for the best user experience is from 110 revolutions per minute to 210 revolutions per minute.
It can be understood that this application first obtains the preset rotation speed range in which the average value of the preset user comfort score is higher than the preset score through experiments. After the electric nail clipper is turned on, the speed of the cutter blade of the electric nail clipper is controlled to be at this preset speed. Within the range, compared with conventional electric nail clippers which use a fixed speed and a speed of more than 300 rpm, the speed of the cutter blade is greatly reduced, which greatly saves energy and improves the battery life of the electric nail clipper as well as the user experience.

The housing 40 comprises a housing body 41 and a cover 42 detachably coupled to the housing body 41, the housing body 41 has an access hole 43. The cutter assembly 50 comprises a cutter blade 51, a blade housing 52 for receiving the cutter blade 51, a motor 53 and a transmission mechanism 54 coupled to the motor 53 for driving the rotation of the cutter blade 51.
The blade housing 52 has a cutter slot 521 which is aligned with the access hole 43 of the housing body 41, so as to expose the cutter blade 51 and allow the nail of the user to have contact with the cutter blade 51 in the blade housing 52 for nail trimming. In this embodiment, the alignment of the access hole 43 and the cutter slot 521 simplifies nail placement, allowing the user to trim nails precisely without requiring advanced dexterity.
The blade housing 52 acts as a protective barrier, exposing only the necessary portion of the cutter blade 51 while shielding other moving parts, reducing the risk of accidental injury. The cover 42 adds an extra layer of safety by concealing the cutter assembly when not in use.
In this embodiment, the housing body 41 can be made of a plastic material, chosen for its lightweight properties, cost-efficiency, and ease of molding into ergonomic shapes. This makes the electric automatic nail clipper comfortable to handle and portable, while maintaining structural integrity to protect internal components. The blade housing 52 is made of a rigid metal material for receiving the cutter blade 51, providing the necessary strength and durability to securely hold the cutter blade 51. The metal construction ensures that the blade housing 52 can withstand repeated use and resist deformation or damage from the high-speed motion of the cutter blade 51.
In addition, the superior thermal and mechanical stability of the metal material ensures that the blade housing 52 maintains its structural integrity under the stresses generated by the rotating blade. The robust metal construction of the blade housing 52 enhances the precision of the motion of the cutter blade 51, ensuring smooth and efficient nail trimming. The rigid structure minimizes vibrations and blade misalignment, improving the overall user experience. The secure containment of the cutter blade 51 within a metal housing adds an extra layer of protection, reducing the risk of blade exposure or accidental damage.
The motor 53 and the transmission mechanism 54 are arranged to enable high-speed, consistent rotation of the cutter blade 51, ensuring quick and smooth trimming. This reduces the effort required by the user compared to manual nail clippers.
In this embodiment, the housing body 41 of the housing 40 has an end surface 401, the access hole 43 is elongated in shape and is formed in a central area of the end surface 401 to align with the cutter slot 521. The end surface 401 is a concave surface while the access hole 43 is formed at a bottom of the concave surface in a manner that two curved surfaces 4011 are respectively formed at two sides of the cutter slot 52.
The concave end surface 401 naturally conforms to the curvature of the fingertips of the user, offering a comfortable grip and guiding the nail into the correct position for trimming. This design improves user confidence and convenience, particularly for individuals with limited dexterity.
The central alignment of the access hole 43 with the cutter slot 521 ensures accurate and consistent engagement between the nail and the cutter blade 51. This precise alignment reduces the risk of uneven cuts or accidental injury.
The recessed placement of the access hole 43 at the bottom of the concave surface 401 creates a natural guide for the user to position their nail accurately. The design minimizes the likelihood of misalignment, enhancing the overall effectiveness of the nail trimming process.
The curved surfaces 4011 on both sides of the access hole 43 provide additional protection by shielding the cutter blade 51 from accidental contact. This design reduces the risk of injury during operation or when the device is not in use.
The contoured shape of the concave surface 401, with the two curved surfaces 4011, gives the nail clipper a sleek and modern look, making it visually appealing while also improving functionality.
When the user is using the electric automatic clipper to trim his or her nails, the nail of the fingertip is placed into the cutter slot 521 to have contact with the cutter blade 51, the finger tip will vibrate when the cutter blade 51 is in operation, in case when the fingertip is leaving the cutter slot 521, the two curved surfaces 4011 functions to guide the finger tip to slide back to the cutter slot 521.
In other words, during operation, the vibration caused by the rotating cutter blade 51 may lead to the fingertip unintentionally moving away from the cutter slot 521. To address this, the two curved surfaces 4011 located on either side of the access hole 43 play a critical role in guiding the fingertip back into proper alignment with the cutter slot 521. The curved surfaces 4011 naturally direct the fingertip to the central position of the cutter slot 521 without requiring force or excessive effort. This ergonomic feature is especially beneficial for users with limited dexterity or visual impairments. The vibrations experienced by the fingertip during operation are effectively mitigated by the guiding action of the curved surfaces 4011, ensuring the fingertip stays in position for consistent nail trimming. This helps enhance the overall user experience.
The blade housing 52 comprises a slot portion 522 which is a part of the blade housing 52 slightly extending out of the access hole 43, the cutter slot 521 is extended through the slot portion 522 for guiding the nail of the user to come in contact with the cutter blade 51.
Accordingly, the slot portion 522 provides a defined path for the user's nail to reach the cutter blade 51, ensuring proper alignment. This feature minimizes the risk of uneven trimming caused by misaligned nail placement. By slightly extending beyond the access hole 43, the slot portion 522 creates an intuitive and accessible entry point for the user's nail. This design simplifies the process, especially for users with limited dexterity or those unfamiliar with the operation of the electric automatic nail clipper.
The slot portion 522 has an inclined guiding inner surface 523 to define the cutter slot 521 and facilitate the guiding of the nail of the user into the chamber of the blade housing 52 to come in contact with the cutter blade 51.
The inclined guiding inner surface 523 provides a natural slope that gently guides the nail of the user into the cutter slot 521. This ensures effortless alignment of the nail with the cutter blade 51, reducing user effort and preventing accidental misplacement. By defining the edges of the cutter slot 521 with an inclined surface, the design ensures that only the nail enters the trimming chamber. This prevents the skin of the fingertip from accidentally coming into contact with the moving blade, enhancing trimming precision and user safety.
A width of the cutter slot 521 is preferred to be less than 1.5 mm, allows for precise engagement between the nail and the cutter blade 51. This ensures clean, accurate trimming without the risk of over-cutting or damaging surrounding skin. By limiting the width of the cutter slot 521 to less than 1.5 mm, the design minimizes the likelihood of the fingertip inadvertently entering the trimming area. This protects the user from potential injury and enhances confidence during use.
As shown in
The narrower central portion ensures precise trimming by securely holding the nail in the ideal cutting position. This design minimizes the risk of misalignment, ensuring a clean and smooth cut. The wider ends provide a smooth entry point for the nail, reducing the effort required to position the nail accurately in the slot. This gradual widening acts as a natural guide, funneling the nail toward the center where precision cutting occurs.
As shown in
During nail trimming, users typically proceed in small, progressive steps. Without a safeguard, there is a risk of the cutter blade engaging the nail beyond the intended length, especially if trimming continues after the nail has been fully shaped.
The column transition surface 524 acts as a protective buffer, increasing the distance between the cutter blade 51 and the fingertip. This design minimizes the risk of cutting into the nail bed or excessively shortening the nail.
In scenarios where external forces, such as accidental strikes on the arm or hand, could cause unintended movement, the column transition surface 524 ensures that the nail clipper does not inadvertently over-trim the nail. The width range of 0.1 mm to 0.8 mm is optimized to focus the cutting action on the excessively long portion of the nail while preventing trimming beyond the safe threshold.
The combination of the inclined guiding inner surface 523 and the column transition surface 524 guides the nail seamlessly into the cutter slot 521, reducing user effort and improving the overall clipping experience.
In this embodiment, as shown in
The first transmission gear 542 comprises a first gear portion 5421 which is engaged with the first driving gear 541, and a second gear portion 5422, the second transmission gear 543 comprises a first gear portion 5431 which is engaged with the second gear portion 5422 of the first transmission gear 542 and a second gear portion 5432 which is engaged with the second driving gear 544.
Accordingly, when the motor 53 is in operation, the first driving gear 541 will be driven to rotate by the motor 53, so that the first transmission gear 542 and the second transmission gear 543 will be driven to rotate, so as to drive the second driving gear 544 to rotate, and finally, the cutter blade 51 is driven by the second driving gear 544 to rotate.
In this embodiment, the multi-step gear train ensures that rotational motion is transmitted smoothly from the motor 53 to the cutter blade 51. This design minimizes power loss and enhances efficiency. The inclusion of multiple gears enables speed reduction or amplification as needed, ensuring the cutter blade 51 rotates at the optimal speed for precise and safe nail trimming. In addition, the gear train configuration effectively amplifies torque, allowing the cutter blade 51 to handle varying nail thicknesses without stalling or losing efficiency. By distributing mechanical load across multiple gears, the mechanism minimizes wear and tear on individual components, enhancing the product's lifespan.
The staggered gear engagement of the first transmission gear 542 and the second transmission gear 543 ensures stable operation, reducing noise and vibration during use. This significantly improves the user experience.
The coaxial alignment of the gears allows for a compact housing, ensuring the nail clipper remains lightweight and ergonomic without compromising functionality. The direct coaxial connection between the second driving gear 544 and the cutter blade 51 ensures consistent and reliable rotation, delivering precise and smooth cuts every time
According to this embodiment, the cutter blade 51 of the electric automatic nail clipper is controlled by the control assembly 60 to run according to a preset speed and the first preset speed is within a preset speed range of 210 revolutions per minute to 110 revolutions per minute.
In this embodiment, as shown in
The blade housing 42 is disposed in the receiving cavity 414 of the housing body 41 and connected to the housing body 41, the cutter blade 41 is rotatably disposed in the blade housing 42.
As shown in
The movable lid 46 is a pusher element which is rotatably mounted at the debris discharging port 44, a pusher end 461 of the movable lid 46 is adjacent to the cutter blade 41 that can be pushed to enter the debris guiding passage 45 while the other end 462 is located at an outer side of the debris discharging port 44, so that the movable lid 46 is in an inclined state, and the debris discharging port 44 is in an open state for allowing the debris in the chamber 420 of the blade housing 52.
In this embodiment, a bottom 511 of the cutter blade 51 is exposed to the debris guiding passage 45 in a manner that a tool can be inserted into the debris guiding passage 45 to have a contact with the bottom 511 of the cutter blade 51.
Accordingly, when the electric automatic nail clipper is operating, debris build up will take place within the blade housing 52 to cause the blade housing 52 become clogged with the debris, the clogged cutter blade 51 may cause the electric automatic nail clipper to vibrate excessively or operate noisily, reducing the overall user experience. However, the design of the debris guiding passage 45 allow the bottom 511 of the cutter blade 51 to be exposed, so that the user is able to easily access or clean the clogged cutter blade 51 by penetrating a tool into the debris guiding passage 45 through the debris discharging port 44. As a result, maintenance becomes easy, and the performance and longevity of the electric automatic nail clipper are compromised.
Accordingly, the debris guiding passage 45 and the movable lid 46 enable quick and easy clearing of debris that may clog the blade housing 52. The user can access the passage and discharging port without disassembling the clipper, simplifying the cleaning process. The exposed bottom 511 of the cutter blade 51 provides a direct point of access for tools to dislodge accumulated debris.
Particularly, the user may use a tool such as a screwdriver tool to drive the cutter blade 51 to rotate clockwise or counterclockwise, so as to remove the debris clogged between the cutter blade 41 and the blade housing 52. In other words, the cutter blade 51 is designed to facilitate manual rotation in both directions, enabling comprehensive cleaning of debris from all angles. This feature eliminates the need for disassembly, simplifying the maintenance process. The bottom of the cutter blade 51 is positioned in such a way that tools like screwdrivers can easily make contact. This user-friendly access point ensures that even individuals with minimal technical knowledge can perform cleaning tasks.
As shown in
In this embodiment, the protruding structure 47 comprises a protruding cover 471 and a transparent layer 472 which is mounted to the protruding cover 471 at a side facing towards the cutter slot 521 to define a cavity 473 within the protruding cover 471 and the transparent layer 472.
The control assembly 60 comprises a controller 61, a power module 62 for supplying power to the controller 61, a power switch 63 electrically connected to the controller 61 and the power module 62, an operation switch 64 electrically connected to the controller 61, a lighting element 65 electrically connected to the controller 61. The power module 62 may comprises a rechargeable battery with is provided with an electrical charging interface 621 installed on the housing body 41.
The lighting element 65 is disposed into the cavity 473 of the protruding structure 47 in a manner that light beams of the lighting element 62 is reflected towards the transparent layer 472 by an inner surface of the protruding cover 471, so as to project to the fingertip of the user and illuminate the area of the cutter slot 521.
The lighting feature is particularly beneficial for the user trimming nails in dimly lit environments, ensuring accuracy without needing additional lighting sources. The reflected and directed beams concentrate light only where it is needed, preventing unnecessary light dispersion. The lighting element 65 and the protruding structure 47 are aesthetically pleasing and do not disrupt the compact design of the electrical automatic nail clipper.
The power switch 63 is mounted to a side of the housing body 41, the operation switch 64 is mounted on a side surface 402 of the housing body 41 on the first housing portion 412 which is adjacent to the protruding structure 47. The movable lid 46 and the debris discharging port 44 are formed at the second housing portion 413.
In this embodiment, when the power switch 63 can be embodied as a button which is pressed to power on the electrical automatic nail clipper, the lighting element 65 is turned on. When a fingertip of one hand of the user is placed into the cutter slot 521 while a finger of the other hand of the user is pressed on the operation switch 64, the cutter blade 51 will be activated to rotate to start to trim the nail of the fingertip of the one hand of the user. Accordingly, the arrangement of the power switch 63 and the operation switch 64 prevent the unintentional activation of the cutter blade 51 by a child.
In other words, while one hand positions the fingertip within the cutter slot 521, the other hand is required to press the operation switch 64. This deliberate dual-hand engagement ensures that the cutter blade 51 operates only when intended.
The operation switch 64 can be a button. Alternatively, the operation switch 64 is a capacitive sensing element which is electrically connected to the control circuit board of the controller 61 that is integrated with a capacitive touch controller chip, when a finger of the user approaches the surface of the operation switch 64, the finger disrupts the electromagnetic field around the capacitive sensing element and cause a change in capacitance, and this change is detected by the capacitive touch controller chip, triggering a response of activating the operation of the motor 53.
The operation switch 64 can be embodied as a fingerprint recognition element, and the control circuit board of the controller 61 is provided with fingerprint recognition module. The user can enter fingerprint enrollment mode b specific steps in the software program of the electric automatic nail clipper. In this mode, valid user fingerprints are recorded and stored in the control module.
When turning on the electric automatic nail clipper, a mechanism similar to a child lock is employed: the user holds the power switch 63 for a few seconds to enter standby mode. At this point, placing a registered finger on the fingerprint recognition area of the operation switch 64 triggers the fingerprint recognition module to identify the user's fingerprint and send the information to the controller 61. The controller 61 compares the scanned fingerprint against the pre-stored fingerprints. If the comparison is successful, the controller 61 activates the cutter blade 51. If the comparison fails, the cutter blade 61 will not start, and the lighting element 65 will flash to inform the user to input a valid fingerprint.
The control assembly 60 further comprises one or more object detection sensors 66 provided adjacent to the cutter slot 521. In this embodiment, the control assembly 60 comprises two object detection sensors 66 which are respectively provided at two sides of the protruding structure 47 and are mounted to the end surface 401 of the housing body 41.
A distance between the two object detection sensors 66 is generally designed to be no less than 23 mm. This ensures that, during thumb trimming, an adult's thumb cannot simultaneously block both sensors. Typically, the width of most adult thumbs is less than 23 mm.
Each of the object detection sensors 66 can be but mot limited to an infrared sensor, an ultrasonic sensor, a radar distance sensor, and a laser distance sensor. As an example, each object detection sensor can be an infrared sensor.
Accordingly, in this embodiment, the electric automatic nail clipper incorporates an object detection safety mechanism utilizing infrared sensors to prevent accidental injury. This system is designed to discern normal nail-trimming conditions from abnormal interactions with unintended objects or body parts.
When trimming nails, a single finger is inserted into the cutting slot 521. The rest fingers are retracted, leaving the object detection sensors 66 unobstructed. In this case, the infrared light emitted by an emitting diode of the infrared sensor does not encounter a reflecting surface, resulting in no signal being sent to a receiving diode of the infrared sensor. The controller 61 interprets the absence of a reflected signal as normal trimming conditions, allowing the motor 53 to drive the cutter blade 51 for nail trimming.
If a larger object, such as a face, or other body part, obstructs the cutting slot 521 and covers one or more object detection sensors 66, the emitted infrared light from emitting diode of the infrared sensor is reflected back to the receiving diode of the infrared sensor. The receiving diode transmits the reflected signal to the controller 61. The controller 61 processes this signal and determines that an abnormal obstruction is present. The controller 61 then sends a command to halt motor operation, so as to immediately stop the rotation of the cutter blade 51.
The object detection mechanism is a proactive safety feature that halts the motor 53 when unintended objects obstruct the cutting slot. This minimizes the risk of injury to other body parts, such as the face. The use of infrared sensors ensures rapid detection of obstructions, allowing the controller to respond instantly to potential hazards. The system intelligently distinguishes between normal nail trimming (one finger in the cutter slot 521) and abnormal conditions (e.g., multiple obstructions or larger objects). This ensures uninterrupted operation during proper use while maintaining safety. The controller 61 processes signals accurately to avoid false alarms, ensuring that the motor 53 halts only when truly necessary.
The control assembly 60 further comprises an angle detection sensor 67 which is an angle sensor, a tilt sensors, or a MEMS accelerometer. The angle detection sensor 67 monitors the orientation of the nail cutter during use. If the device is tilted beyond an optimal angle, it can alert the user to prevent uneven trimming or accidental injuries.
This feature is particularly beneficial for the user who may lack experience or dexterity, such as children or individuals with limited hand mobility. By detecting improper angles, the controller 61 can dynamically adjust the operation, such as reducing the speed of the cutter blade 51, to enhance precision and ensure safe nail trimming.
The lighting element 65 provides additional illumination during nail trimming, If the user's grip is incorrect or suboptimal, the controller 61 triggers the lighting element 65 to flash. This serves as an intuitive, real-time reminder for the user to adjust their grip posture. This feature is particularly beneficial for beginners or users who may be unaware of the ideal grip for safe and effective nail trimming.
