Definitions
- the invention relates to an electric shaving apparatus with a shaving foil and a shaving head which interacts with the shaving foil and which is driven by a possibly electronically clocked motor.
- the wear to which the shaving foil is subjected depends on the friction between the shaving foil and the blade block which is moved in a form-fitting manner relative to the shaving foil.
- the foil adapts to the contour of the face to be shaved and the contour of the shaving head, which means that the wear also depends significantly on the load or from the respective user guidance.
- the shaving apparatus of the type mentioned at the outset essentially consists in that a display device is provided which is connected to an operating time counter and / or a device for detecting the load on the shaving foil and an evaluation circuit.
- a display device when it displays a corresponding signal, advises the user to change the foil and thus ensures that excessively worn shaving blades are no longer used. It is not readily possible for the user of a shaving apparatus to recognize the correct point in time at which a shaving foil is to be changed, since a defective shaving foil is primarily recognized by the injuries already occurring. With such a display device
- such a display device can interact with an operating time counter and after a predetermined operating time
- Counting can be used on the basis of an autonomous oscillator, for example as a commercially available driver module, such a determination of the operating time depending on the on / off switch of the shaving apparatus naturally only allowing a relatively rough estimate of the actual wear of the shaving foil. In many cases, however, such a rough estimate is already sufficient. An improved estimate of the actual wear of the shaving foil is obtained if the actuation of the display device also includes an evaluation of other operating parameters, for example the power consumption or the like.
- the design according to the invention is such that the operating time counter is triggered by the timing of the motor, a combination of the timing of the timing and the timing of the motor making a combined statement about the load on the shaving foil possible .
- the design according to the invention is such that the device for detecting the load on the shaving foil is formed by a power consumption measuring device, the measured values of which are connected to the display device via an evaluation circuit, in particular an integrator.
- the integrated power consumption gives the possibility of issuing a shaving foil recommendation independently of the time that has actually elapsed, the power consumption naturally being integrated via the power consumption in the unit of time.
- the design according to the invention can be such that the device for detecting the load on the shaving foil comprises pressure sensors which cooperate with the shaving foil, such a recording of measured pressure values additionally taking into account the most frequent operator errors when using the electric shaving apparatus .
- Such a display device with which reference is made to the necessary film change, can in turn be deleted in various ways. It is an advantage.
- the design for this purpose is such that the display device can be erased via a switch contact which resets the counter, the switch contact preferably being mechanically coupled to the shaving foil and being automatically operable when the shaving foil is changed. In particular with mechanical coupling of the switching contact with the shaving foil, after the
- the training can be carried out in a particularly simple manner in such a way that the counting or evaluation circuit connected to the display device has a flip-flop that can be set and reset, which can be set and set by the counting or evaluation circuit a switch contact can be reset, so that even with the least amount of electronic effort, it will be sufficient.
- FIG. 1 shows a first embodiment of the circuit arrangement with a simple counting device
- FIG. 2 shows a schematic representation of the combination of the evaluation 0 of engine timing and oscillator signals.
- Fig. 1 schematically indicates the engine timing.
- the engine cycle or. a clock signal is fed to a time counter 2, the output signals being fed to the display device 4 via a resettable 5 flip-flop 3.
- An external switch contact, schematically indicated by 5, is connected to the resettable flip-flop 3, which set the flip-flop and thus the indicator or. the display device 4 causes.
- the display device 4 can be formed by an LED or a corresponding symbol of an LCD.
- l can be such that, for example, the corresponding indicator 4 is displayed after 30 or 35 hours of operation.
- the engine timing is indicated schematically in FIG.
- the pulse shape of the oscillator signals is shown schematically at 7.
- the signals existing in parallel in this way are fed to an AND module 8 and subsequently evaluated in a counter 9.
- the connection of the engine timing with the oscillator also shows the load state in this way and only the signals linked in this way are the counter 9 and subsequently the flip-flop 3 or the indicator 4, as they were shown in Fig.l. , fed.
- the oscillator frequency is selected to be significantly higher than the clock frequency of the motor.
