Abstract

A hair trimmer includes a cutting head and a body configured for easy reach of the hard to reach places, such as behind ears. This is achieved by shaping a front portion of the body to have cutouts behind the cutting head, which allow the trimmer to navigate around parts such as an ear. The cutouts also improve air flow around the front of the trimmer's body, thereby improving performance and durability of internal trimmer components through better cooling. The walls of the cutouts may have air ducts to further improve the cooling of the internal components. The cutouts also reduce the vibration of the cutting head and the body, leading to better trimming experience for the user and to improved durability of the trimmer. The method of using a trimmer with a cutting head and a body configured for easy reach of hard to reach places, such as behind ears, is also described.

Claims (54)

1. A device for trimming hair, comprising:

a body comprising 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;

a plurality of air ducts provided in at least one of the first cutout or the second cutout, wherein the plurality of air ducts include bores extending from the front portion of the body into an internal section of the body, and facilitating cooling of internal components provided in the interior section of the body; and

a cutting head attached to the front portion of the body.

2. The device of claim 1 , wherein the body further comprises, when in an upright state:

a top portion and a bottom portion on two opposite ends of a height of the body;

a left portion and a right portion on two opposite ends of a width of the body; and

a back portion, such that the front portion and the back portion are on two opposite ends of a length of the body,

wherein the first cutout extends inward from a position defined by the front portion, the top portion, and the left portion, and the second cutout extends inward from a position defined by the front portion, the top portion, and the right portion.

3. The device of claim 2 , further comprising an electric cord attached to the back portion of the body.

4. The device of claim 3 , wherein the electric cord is a swivel cord.

5. The device of claim 2 , wherein the internal section of the body is provided between the top portion and the bottom portion of the body.

6. The device of claim 1 , wherein the bores of the plurality of air ducts extend through a back surface defined in the at least one of the first cutout or the second cutout.

7. The device of claim 6 , wherein the bores of the plurality of air ducts are oriented substantially perpendicular to a bottom surface defined in the at least one of the first cutout or the second cutout.

8. The device of claim 1 , wherein the cutting head comprises a stationary blade and a moving blade.

9. The device of claim 8 , wherein each of the blades comprises teeth.

10. The device of claim 1 , wherein the body has a cylindrical shape.

11. The device of claim 1 , wherein each of the first cutout and the second cutout comprises at least one surface and wherein the bores of the plurality of air ducts are provided in the at least one surface of the at least one of the first cutout or the second cutout.

12. The device of claim 11 , wherein the cutting head comprises a stationary blade and a moving blade.

13. The device of claim 12 , wherein each of the blades comprises teeth.

14. The device of claim 1 , wherein the bores of the plurality of air ducts facilitate ventilation of the internal components in the body.

15. A device for trimming hair, comprising:

a body including, in an upright state, a front portion and a back portion provided 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, the body defining a plane between the front and back portions;

a plurality of air ducts positioned; and

a cutting head attached to the front portion comprising a stationary blade and a moving blade, each of the blades comprising teeth,

wherein 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,

wherein the plurality of the air ducts are provided in at least one of the first depression or the second depression, and

wherein the plurality of air ducts include bores extending from the front portion of the body into an internal section of the body, and facilitating cooling of internal components provided in the interior section of the body.

16. The device of claim 15 , wherein the internal section of the body is provided between the top portion and the bottom portion of the body.

17. The device of claim 15 , wherein the bores of the plurality of air ducts extend through a back surface defined in the at least one of the first depression or the second depression.

18. The device of claim 6 , wherein the bores of the plurality of air ducts are oriented substantially perpendicular to a bottom surface defined in the at least one of the first depression or the second depression.

19. The device of claim 15 , further comprising an electric cord attached to the back portion of the body.

20. The device of claim 19 , wherein the electric cord is a swivel cord.

21. The device of claim 15 , wherein at least one of the blades extends beyond the right portion and the left portion of the body at the front portion of the body.

22. The device of claim 15 , wherein the bores of the plurality of air ducts facilitate ventilation of the internal components in the body.

23. A hair trimmer, comprising:

a body comprising a front portion which has at least one cutout;

a plurality of air ducts provided in the at least one cutout; and

a cutting head attached to the front portion of the body and comprising teeth along one edge of the cutting head,

wherein the plurality of air ducts include bores extending from the front portion of the body into an internal section of the body, and facilitating cooling of internal components provided in the interior section of the body.

24. The trimmer of claim 23 , wherein the at least one cutout includes a plurality of cutouts, and wherein the front portion comprises the plurality of cutouts at two adjacent positions of the front portion of the body.

25. The trimmer of claim 23 , wherein the bores of the plurality of air ducts enable ventilation of the body.

26. The trimmer of claim 23 , further comprising an electric cord attached to, in the upright state, a back portion of the body.

27. The trimmer of claim 26 , wherein the electric cord is a swivel cord.

28. A method for trimming hair, comprising the steps of:

providing a hair trimmer comprising:

a body having, in an upright state, 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,

wherein 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,

wherein at least one of the first depression or the second depression has a plurality of air ducts provided therein, and

wherein the plurality of air ducts include bores extending from the front portion of the body into an internal section of the body, and facilitating cooling of internal components provided in the interior section of the body;

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
