Electronic system for monitoring the amount of shaving fluid in shavers or razors with a shaving fluid reservoir

In modern shavers or razors shaving fluids are used for a better shave. Such fluids are stored in replaceable reservoirs, for instance flexible cartridges. For a user it is inconvenient when a reservoir exhausts during shaving. It is also difficult for a user to estimate if a shave can be completed with the remaining fluid in the reservoir.

A system is disclosed that informs the user how much fluid is left in the reservoir. A warning signal can be given to the user when the amount of fluid is insufficient for a complete shave.

For this purpose the shaver is provided with a fluid pump, which pumps a fixed amount of fluid per time unit. When the pump is activated for a certain time, a known amount of fluid is dispensed. When the starting fluid volume of the reservoir is known, an electronic system can calculate the total dispensed amount of fluid and the rest amount of fluid left in the reservoir. The amount of fluid in the reservoir can be communicated to the user, for instance, by means of an LCD display or one or more indication LEDs (Figure 1). When the critical amount of fluid for a new shave is reached, the system may additionally give a warning signal to the user. This signal can, for instance, be audible or visible. The system also can calculate the fluid consumption behaviour of the user, which will be different amongst users and use this inform...
