Manual toothbrush having replaceable head

A replaceable head for removeable connection with a manual toothbrush handle, the replaceable head comprising:

• a first end, a second end opposite to the first end, a neck extending between the first end and the second end, and a bristle carrier disposed adjacent to the first end;
• wherein the second end comprises a second-end opening leading into a hollow portion of the neck, the hollow portion being defined by an inner wall of the neck;
• wherein the second end comprises a chamfered surface structured and configured to mate with a corresponding chamfered surface of the manual-toothbrush handle;
• wherein the inner wall comprises a recess for receiving a spring-loaded ball associated with a connector of a toothbrush handle,
• wherein the head comprises at least one rib for precisely adjusting the head on the connector of the handle, the at least one rib extending from the inner wall within the hollow portion to the recess for receiving a spring-loaded ball;
• and
• wherein a distinct haptic feedback is provided to a user upon an engagement interaction between the recess and the spring-loaded ball as the spring-loaded ball snaps into the recess, to alert a user that the head is securely connected to the toothbrush handle as the engagement interaction between the recess and the spring-loaded ball becomes invisible when the head and the handle are connected together.

• wherein the second end comprises an opening leading into a hollow portion of the neck, the hollow portion being defined by an inner wall of the neck, wherein the inner wall comprises a recess for receiving a spring-loaded ball associated with a connector of a toothbrush handle, wherein the recess is visible only through the opening;
• wherein the second end comprises a chamfered surface structured and configured to mate with a corresponding chamfered surface of the handle;
• wherein the opening and the hollow portion are structured and configured for the recess to receive a connector associated with the handle and comprising a spring-loaded ball, to displace the spring-loaded ball from a first position to a second position upon partial connection of the head with the handle, and then permit the spring-loaded ball to return to the first position upon a complete connection of the head with the handle, along with a distinct haptic feedback to alert a user that the head is securely connected to the handle, and
• wherein the head comprises at least one rib for precisely adjusting the head on the connector of the handle, the at least one rib extending from the inner wall within the hollow portion to the recess for receiving a spring-loaded ball.
