The following description relates to a hair trimmer including a body and a cutting head. Also, a method of using a hair trimmer is described. For example, a hair trimmer used for removing unwanted hair from difficult to reach regions is described.
Hair trimmers are typically used by consumers for a number of different applications such as trimming moustaches, nose hair, hair on the temples, hair behind the ears, and other hair. One example of a hair trimmer is a facial hair trimmer. In using a hair trimmer, the user typically purchases the trimmer that includes a removable cutting head, and then uses the trimmer on a daily, weekly, or other regular interval. Cutting heads may be sold separately and may need to be replaced once the original cutting head becomes dull.
After each use of the hair trimmer, some maintenance steps may be performed, which include cleaning the cutting head with a brush or under a stream of running water. A trimmer brush is sometimes provided for cleaning the cutting head of the trimmer. The motor in the body of the trimmer may need to cool off between consecutive applications of the trimmer. The trimmer may be corded or cordless. A cordless trimmer typically has batteries, which may need to be replaced or recharged when they drain out. A corded trimmer may need to be plugged into an electric outlet to be charged.
Typically, the body of a hair trimmer is separate from the trimmer head and used to control the trimmer head for trimming a users hair. The body of a trimmer is typically a long extension in a longitudinal direction that is grasped by the user. Because a trimmer body is relatively large and long as compared to a trimmer head, the trimmer body may prevent the trimmer head from trimming unwanted hair in difficult to reach regions.
In an aspect, a device for trimming hair includes a body including a front portion, a first cutout, and a second cutout, the first cutout and the second cutout positioned at the front portion of the body, and a cutting head attached to the front portion of the body.
In another aspect, a device for trimming hair includes a body with a front portion and a back portion on two opposite ends of a length of the body, a top portion and a bottom portion on two opposite ends of a height of a body, and a left portion and a right portion on two opposite ends of a width of the body, and a cutting head attached to the front portion including a stationary blade and a moving blade, each of the blades including teeth extending substantially perpendicular to the top portion, where the body has a first depression extending inward from a position defined by the front portion, the top portion, and the left portion, and a second depression extending inward from a position defined by the front portion, the top portion, and the right portion.
In an additional aspect, a hair trimmer includes a body including a front end, and a cutting head attached to the front end of the body and including teeth along one edge of the cutting head, where the front end is configured to allow the cutting head of the trimmer to reach regions behind a user's ear.
In yet another aspect, a method for trimming hair includes providing a hair trimmer including a body having a front portion and a back portion on two opposite ends of a length of the body, a top portion and a bottom portion on two opposite ends of a height of the body, and a left portion and a right portion on two opposite ends of a width of the body, and a cutting head attached to the front portion comprising a stationary blade and a moving blade, each of the blades comprising teeth extending substantially perpendicular to the top portion, where the body has a first depression extending inward from a position defined by the front portion, the top portion, and the left portion, and a second depression extending inward from a position defined by the front portion, the top portion, and the right portion, positioning the trimmer proximate to an area to be trimmed such that a portion of a user's body extends within the first depression or the second depression, and trimming the hair.

Referring to
Still referring to the example illustrated in
In an example, the body 101 is substantially cylindrical, such that the front portion 107 and the back portion 108 are the ends of the cylindrical shape of the body, and the left portion 109, the right portion 110, the top portion 111, and the bottom portion 112 are various portions of the curved surface of a cylindrical shape of the body. In this example, the right cutout 105 extends inward from a position at the intersection of the front, right, and top portions of the body, and the left cutout 106 extends inward from a position at the intersection of the front, left, and top portions of the body.
In some examples, cross-sections of the body 101 perpendicular to a longitudinal axis of the body are substantially rectangular, or substantially circular, or substantially oval, such that the cross-sectional shape and size may vary along the length of the body.
While the examples of the trimmer 100, 1000 described include a cuboidal shape and a cylindrical shape, the invention is not limited to such shapes. Other well known shapes for a hair trimmer 100, 1000 are also included and described to a person having ordinary skill in the art, and may be modified to include such cutouts 105, 1050, 106, 1060 at a front portion of the body 101 as described herein. In the above examples, the cutouts 105, 1050, 106, 1060 allow for cutting hair in hard to reach places, such as behind ears. The cutouts 105, 1050, 106, 1060 create a gap between the cutting head of the trimmer and the trimmer's body, such that an ear or another part may be partially positioned in these gaps while the cutting head reaches the hair that is being trimmed. Without the cutouts, trimming hair in such places would be difficult, or would only be accomplished with an inconvenience or pain of the user.
In an example, the cutouts 105, 1050, 106, 1060 create air pockets between the cutting head of the trimmer and the trimmer's body, such that the internal components of the trimmer are better cooled. Typically, the internal components of the trimmer such as a motor, an electromagnetic coil, or other internal components, become hot during normal operating duty cycle of the trimmer, and may overheat in case of a long continuous operation. This leads to degradation of trimmer's performance or premature failure. In an example, the air pockets created by the cutouts 105, 1050, 106, 1060 lead to lower operating temperatures of the internal components of the trimmer, or improvements in their performance, or extension of their useful life.
In an example, the cutouts 105, 1050, 106, 1060 allow for a reduced vibration of the cutting head of the trimmer and of the trimmer's body. Reduced vibration of the cutting head allows for more precise and more comfortable trimming action. Reduced vibration of the trimmer's body allows for more comfortable handling of the trimmer.
In an example, the trimmer is operated without a cord. In another example, the trimmer operates with a cord. In this example, the trimmer may operate with a swivel cord that is configured to swivel around its own axis while maintaining electrical contact with the trimmer's body. Such swivel action of the cord allows for the user to use the trimmer at various portions of their face without creating kinks in the cord. This leads to increased operating life of a trimmer equipped with a cord.
In an example, a method of using a hair trimmer is provided. In this example, a method of using a hair trimmer includes providing a trimmer, turning on the trimmer, positioning the trimmer in such a way that the cutting head is located in close proximity to the unwanted hair, and trimming the unwanted hair. In another example, a method of using a hair trimmer includes positioning the trimmer in such a way that the cutting head is located in close proximity to the unwanted hair, turning on the trimmer, and trimming the unwanted hair. In an example, a method of using a hair trimmer includes providing a trimmer that has a cutting head attached to a body where the body is configured with cutouts on the side of the body located next to the cutting head.
