Removable razor cartridge with magnetic attachment
A shaving system has a razor cartridge with a blade unit and handle connection structure having a first magnetic element, and a handle having a magnet mounted to the handle and an ejector button having a second magnetic element, movable between a first position and a second position. When the razor cartridge is attached to the handle and the ejector button is in its first position, the second magnetic element of the ejector button is positioned between the magnet of the handle and the first magnetic element of the razor cartridge. When the ejector button is moved to its second position, magnetic attraction between the magnet and the first magnetic element is reduced and the razor cartridge is unattached from the handle. When a user releases the ejector button, magnetic attraction between the magnet and the second magnetic element returns the ejector button to its first position.
1. A shaving system comprising:
a razor cartridge including a blade unit, and a handle connection structure having a first magnetic element, and
a handle having a cartridge connection end having a magnet mounted to the handle, and an ejector button having a second magnetic element, the ejector button being movable by a user between a first position, and a second position, and wherein,
when the razor cartridge is attached to the handle and the ejector button is in its first position, the second magnetic element of the ejector button is positioned between the magnet of the handle and the first magnetic element of the razor cartridge;
when the user moves the ejector button to its second position, magnetic attraction between the magnet and the first magnetic element is reduced such that the razor cartridge is unattached from the handle; and
when the user releases the ejector button at its second position, magnetic attraction between the magnet and the second magnetic element moves the ejector button to its first position.
2. The shaving system of claim 1 , wherein when the razor cartridge is attached to the handle and the ejector button is in its first position, the second magnetic element of the ejector button is positioned one of directly and indirectly between the magnet of the handle and the first magnetic element of the razor cartridge.
3. The shaving system of claim 1 , wherein the blade unit is pivotally connected to the handle connection structure.
4. The shaving system of claim 1 , wherein the ejector button is slidable on the handle between the first position and the second position.
5. The shaving system of claim 1 , wherein the second magnetic element has an aperture.
6. The shaving system of claim 1 , wherein, the magnet is received in a recess of the handle.
7. The shaving system of claim 1 , wherein the first magnetic element is selected from the group consisting essentially of steel, mild steel, and nickel plated mild steel.
8. The shaving system of claim 1 , wherein the second magnetic element comprises soft ferrite.
9. The shaving system of claim 8 , wherein the soft ferrite is one of manganese-zinc ferrite and nickel-zinc ferrite.
10. The shaving system of claim 1 , wherein movement of the ejector button from the first position to the second position is in a direction towards the attached razor cartridge.
11. The shaving system of claim 1 , wherein, when the user releases the ejector button at its second position, movement of the ejector button to its first position is achieved by the magnetic attraction between the magnet and the second magnetic element.
