Abstract

A razor head may comprise one or more cutting members. The razor head of the first aspect further comprises a vibrating component configured to generate vibrations. The razor head of the present disclosure further comprises a structural element configured to transmit the vibrations from the vibrating component to the one or more cutting members. Furthermore, the vibrating component of the first aspect is disposed away from respective one or more cutting edges of the one or more cutting members towards an inner portion of the razor head, wherein the vibrating component is connected with the structural element. In the present disclosure, the structural element extends from the vibrating component towards the one or more cutting members.

First claim

The invention claimed is:

1. A razor head comprising:
one or more cutting members;
two or more vibrating components configured to generate vibrations;
two or more structural elements configured to transmit the vibrations from the two or more vibrating components to the one or more cutting members,
wherein the two or more vibrating components are disposed away from respective one or more cutting edges of the one or more cutting members towards an inner portion of the razor head,
wherein the two or more vibrating components are connected with the two or more structural elements,
wherein the two or more structural elements extend from the two or more vibrating components towards the one or more cutting members,
wherein each vibrating component of the two or more vibrating components is connected with respective structural element of the two or more structural elements, and
wherein a first structural element of the two or more structural elements is disposed on a first side of a longitudinal extension of the razor head and a second structural element of the two or more structural elements is disposed on a second side of the longitudinal extension of the razor head that is opposite to the first side.

2. The razor head of claim 1 , wherein the two or more vibrating components comprise one or more of a piezoelectric element, an electrostrictive element, a ferroelectric element and a magnetostrictive element.

3. The razor head of claim 1 , wherein the two or more structural elements are configured to be in contact with the one or more cutting members at least some time during the operation of the two or more vibrating components to transmit the vibrations from the two or more vibrating components to the one or more cutting members.

4. The razor head of claim 1 , wherein the two or more structural elements are mounted on a rear side of the razor head being opposite to a front side of the razor head that is in contact with a shaving surface when the razor head is in use.

5. The razor head of claim 1 , wherein the two or more structural elements comprise one or more resilient elements, wherein the resilient element of the one or more resilient elements is configured to be in contact with a respective cutting member from the one or more cutting members at least some time during the operation of the two or more vibrating components to transmit the vibrations from the two or more vibrating components to the one or more cutting members.

6. The razor head of claim 5 , wherein the resilient element of the one or more resilient elements of the two or more structural elements is one of a spring, a beam, and a slab.

7. The razor head of claim 5 , wherein the resilient element of the one or more resilient elements, in response to the vibrations produced by the two or more vibrating components during operation, exerts a force onto the respective cutting member,
wherein the force exerted onto the respective cutting member is a function of time.

8. The razor head of claim 5 , wherein the razor head extends longitudinally along a longitudinal axis and the resilient element of the one or more resilient elements of the two or more structural elements extends from the two or more vibrating components towards the respective cutting member from the one or more cutting members along a first direction, wherein the longitudinal axis forms a predetermined angle with respect to the first direction.

9. The razor head of claim 1 , wherein the cutting member of the one or more cutting members is an integrally formed cutting member comprising a radiused bend, and a cutting edge formed at a distal end of the radiused bend,
or wherein the cutting member of the one or more cutting members comprises a blade attached to the cutting member.

10. The razor head of claim 1 , further comprising:
a housing extending longitudinally along a longitudinal axis,
wherein the housing comprises a leading longitudinal side, a trailing longitudinal side, and a recess in between the leading and trailing longitudinal sides for accommodating the one or more cutting members,
wherein the one or more cutting members are disposed at least partially in the recess,
wherein each cutting member of the one or more cutting members is arranged between a leading longitudinal side and a trailing longitudinal side of the recess in a shaving direction of the razor head,
wherein the two or more structural elements are mounted on a rear side of the housing being opposite to a front side of the housing that is in contact with a shaving surface when the razor head is in use.

11. A shaving razor assembly comprising:
a razor head according to claim 1 ;
a razor handle,
wherein the razor head is either releasably attached to the razor handle, integrally formed with the razor handle via a non-pivotable connection, or integrally formed with the razor handle via a pivotable connection.

12. The shaving razor assembly of claim 11 , wherein the razor handle comprises an activating element to operate the vibrating component of the razor head,
wherein the activating element is one of a wireless activating element or an electronic circuit configured to induce vibrations in the vibrating component,
wherein the vibrating component are configured to be operated by the activating element.

13. A kit of parts comprising:
a razor head holder comprising a plurality of razor heads according to claim 1 , and a razor handle.

14. A method for cleaning a razor head comprising:
providing a razor head according to claim 1 ;
providing a razor handle;
wherein the razor handle comprises an activating element to operate the vibrating component of the razor head,
wherein the vibrating component is configured to be operated by the activating element;
activating the activating element of the razor handle to operate the vibrating component of the razor head for cleaning the one or more cutting members of the razor head.

15. A razor head comprising:
one or more cutting members;
a vibrating component configured to generate vibrations;
a structural element configured to transmit the vibrations from the vibrating component to the one or more cutting members,
a housing extending longitudinally along a longitudinal axis,
wherein the vibrating component is disposed away from respective one or more cutting edges of the one or more cutting members towards an inner portion of the razor head,
wherein the vibrating component is connected with the structural element,
wherein the structural element extends from the vibrating component towards the one or more cutting members,
wherein the housing comprises a leading longitudinal side, a trailing longitudinal side, and a recess in between the leading and trailing longitudinal sides for accommodating the one or more cutting members,
wherein the one or more cutting members are disposed at least partially in the recess,
wherein each cutting member of the one or more cutting members is arranged between a leading longitudinal side and a trailing longitudinal side of the recess in a shaving direction of the razor head, and
wherein the structural element is mounted on a rear side of the housing being opposite to a front side of the housing that is in contact with a shaving surface when the razor head is in use.

16. The razor head of claim 15 , wherein the vibrating component comprises one or more of a piezoelectric element, an electrostrictive element, a ferroelectric element and a magnetostrictive element.
