Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a wet razor device.

[0002]

BACKGROUND OF THE INVENTION Unlike the case of electric razors, users of wet razors must replace razor blades, which are subject to severe wear, at relatively short intervals. In this case, the user often has a problem at the right time to replace the blade. For this reason, no fixed time interval can be mentioned. This is because the wear of the razor blade is highly dependent on the frequency of shaving. However, the wear of the razor blade causes further boundary conditions, for example the thickness of the beard or the manner of shaving preparation that is to be carried out and the type of shaving aid used in the form of foam, gel or dust. receive. Time factors are also important. This is because after the first use of the amount of razor blade, this razor blade is subject to natural wear due to corrosive action.

At the same time, however, it is important to replace the razor blade in a timely manner so that the desired shaving finish is obtained with an acceptable shaving time. Moreover, the burden on the skin is reduced by proper use of the razor blade.

[0004]

The problem underlying the present invention is to provide a wet razor device which allows the user to always perform shaving in the best possible conditions.

[0005]

SUMMARY OF THE INVENTION This problem is a wet razor having a grip portion and a blade portion having at least one replaceable razor blade, a device for detecting the use of the razor, and the use of the razor. This is solved by the provision of an electronic evaluation device which is connected to the device for detecting the signal via a signal conductor and an electric display device which is connected to the electronic evaluation device.

The wet razor device thus constructed is suitable for instructing the user to keep his shaving always under the best possible conditions. For this purpose, the frequency of use of a razor with the same blade is first detected by means of a device for detecting the use of a razor. The signal generated thereby reaches via a signal line to an electronic evaluation device, which calculates the estimated wear of the razor blade from the data provided or already present and informs the user of the electrical wear. Appropriate information is given via a display device. In particular, the user can be informed when the razor blade needs to be replaced at the latest. The number of shave made with the same razor blade may also be displayed to the user.

In this way, the user can replace the razor blade in a timely manner, so that the desired perfection of the shave can always be obtained with an acceptable shaving time. The burden on the skin during shaving is thereby reduced to a minimum.

In addition to the display of the number of shavings already performed,
The electronic display can also be used, for example, to show information about inadequate preparation of the skin before shaving. The user can thus know that additional shaving aids, for example in the form of foam, gel or dust, are required for a perfect shave that does not hurt. In addition, the time of day, type of whiskers detected by a suitable sensor or recommendations for replenishment of the blade reserve can be indicated via the electronic display.

In a preferred extension of the invention, the device for detecting the use of a razor has a moisture sensor. This moisture sensor only detects the moisture that is inevitably produced during wet shaving and allows notification of the routine use of the shave.

In the arrangement of the present invention, there is provided a holding portion having a holding body for supporting the razor when not in use. Thereby, after the end of the shave and the fitting of the razor into the holding part, a positive detection of the previous use can be made. An electronic storage device is further connected to the evaluation device in order to enable the evaluation device to check the shaving already done with the same razor blade. It is preferred that the storage device has a characteristic area storage device, so that it is ready to determine the best possible time for razor blade replacement in relation to several factors.

The evaluation device also has a timed element so that time factors can also be taken into account.

The extension of the wet razor device is further characterized in that it is provided with a switching member which is operated in the razor carried by the holder. This makes it possible to detect the use of the razor, irrespective of or supplementing the function of the humidity sensor. In addition, the switching member enables detection of the length of shaving time.

The switching element is preferably designed as an induction switching device, for example with an annular magnet arranged in the razor, into which the holding part of the holding part,
Pins with reed contacts engage without contact. Thereby, a short circuit of the electrical device due to moisture is avoided.

In another configuration, the holding body has a plurality of blade holders.

If possible, it is preferable that the accommodating portion is provided with a monitoring device for the replacement blade. These monitoring devices make it possible to check whether the razor blade is in its respective housing. Furthermore, it can be checked whether it is a new or worn razor blade.

A display element can be attached to each of the receiving parts so that the receiving parts can be visually monitored immediately.

According to the invention, it is further proposed that the evaluation device comprises a counting member which switches the feed each time the razor is used. In order to be able to inform the user of the number of shaves already detected, which can be detected by the counting member, the display device preferably displays a two-digit number in order to show the respective value of the counting member. It is preferable to have a device.

Preferably, the display device is constructed as an LCD display.

The evaluation device and the display device can be arranged, for example, in the holding part. Thus, the razor itself does not require moisture sensitive electrical or electronic components.

Finally, it has been proposed that a manually operable input device be arranged on the holding part. Since the user can input items such as the thickness of the beard or the type of shaving aid to be used through this input device, these items can also be used as data by the evaluation device. This can be done, for example, in the form of a self-learning program, which consists of stored and possibly newly overwritten characteristic regions from stored or respectively realized data. The comparison confirms the recommendations that should be displayed on the display device.

Further details and advantages will be apparent from the following description of the accompanying drawings, in which an embodiment of a wet razor device is shown.

The wet razor device shown in FIG. 1 comprises a wall-mountable holding part 1 and a wet shaving razor 2 which can be fitted into this holding part. The razor blade 2 consists of a grip portion 3 and a blade portion 4, and the razor blade is
In FIG. 1, it is inside the swingable holding body 5 of the holding part 1 and is therefore not visible. The front part of the blade part 4 having a razor blade is supported by a holding body 5, while the razor 2 is supported at its end by a support piece 6 fixedly mounted on the holding part 1. Therefore, it does not fall off from the holding part 1 when not in use. A locking projection, not shown, can be provided so that the razor 2 can only be removed from the holding part 1 by folding it to some mechanical resistance.

As shown in FIGS. 2 and 3, the holding body 5 of the holding part 1 is supported between two holding bodies 1 fixedly connected to the holding part 1 for removing the razor. ing. 2 and 3, the carrier 5 is shown in the open and swung position, in which position the razor can be fitted into or removed from the carrier 5. After the use of the razor 2, the slit-shaped opening 8
It allows the outflow of moisture from the swingable holder 5. The humidity sensor 9 is arranged in the holding body 5,
The razor blade or the razor blade holder comes into contact with this part of the razor when the razor is fitted.

The holding portion 1 has several accommodating portions 10 for replacement blades on the side as individual partition portions. On the front side of the holding part 1 a display element 11 in the form of an LED element is arranged on each housing 10. On the front side of the holding part 1 there is furthermore a display device 12 in the form of an LCD display, suitable for showing a large amount of information. In the immediate vicinity of the display device 12 there is further provided a manually operable input device 13 in the form of a key.

The holding part 1 comprises an induction switch 15 underneath the support surface 14 for the razor 2 shown in FIGS. The pin 16 of the induction switch 15 has a support surface 14
This pin 16 projects into the hole 17 of the razor 2 when the razor 2 is fitted. The hole 17 is surrounded by an annular induction magnet 18.
When the razor 2 having the blade portion 4 with the replaceable razor blade 19 is fitted into the holding body 5 of the holding portion 1 and is engaged by rocking with the support piece 6, the induction switch 1
Since the pin 16 of 5 enters the magnetic field of the induction magnet 18, an electrical signal is generated.

The function and operation of the wet razor device will be described below with reference to the electric circuit configuration diagram of FIG.

In the holding part 1 of the wet razor device is an electronic evaluation device 20 with a storage device 21 for data and characteristic areas. The evaluation device 20 further comprises a timing element 22 and a counting member 23. The evaluation device 20 is provided with a moisture sensor 9, an LCD display device 12, and an input device 13 via signal leads.
And a switching element configured as induction switch 15 is connected. A monitoring device 24 is attached to each of the accommodating portions 10 of the spare blade, and the monitoring device is connected to the evaluation device 20 via a signal conductor. These monitoring devices 2
4 detects whether or not the razor blades 19 are contained in the respective accommodating portions 10 and whether or not these razor blades are new or old razor blades 19.
A battery is incorporated inside the holding part 1 for power supply. Furthermore, an additional power supply connection is provided.

The control program of the display device 12, which is configured as a multi-row LCD display, is started by the razor device 2 being removed from the holding part 1 and the induction switch 15 being operated as a result. In this way, the display device 12 is activated and the user is informed of the number of shavings that have been performed with the same razor blade up to this point via a digital display device with a large two digits. The corresponding count value is stored in the counting member 23 of the evaluation device 20. The symbol on the display 12 informs the user if the razor blade needs to be replaced and if some shaving is still possible in anticipation until the next replacement. Furthermore, the user is informed by reading the monitoring device 24 how many unused razor blades are still in the housing 10 or if these razor blades have to be replaced. It By operating the input device 13, other information, for example, the actual time, is read out via the display device 12.

After the use of the razor, the razor is again fitted into the holding part 1 in the manner described above, which is recorded by the evaluation device 20 via the induction switch 15. At the same time, the moisture sensor 9 detects the moisture still remaining on the razor blade, which is recorded by the evaluation device 20 as a confirmation as to whether the razor has actually been used as prescribed. After this, the value stored in the counting member 23 is increased by one unit and the corresponding information is displayed on the display device 12. Furthermore, the evaluation device 20
A new evaluation of the data is made on the basis of the length of the shaving time detected by the timing element 22 and these data are stored in the storage device 21. The display device 12 is deactivated after 30 seconds.

Besides the removal of the razor, the display device 12 can also be activated by operating the keys of the input device 13.

In a variant of the embodiment shown in the drawings,
The moisture sensor can also be arranged directly on the razor blade or blade part of the razor, in which case proper signal transmission between the razor and the holding part is required. In this embodiment, the humidity sensor is activated several times during shaving, for example during rinsing of the shaving aid from the razor blade. If no further actuation of the moisture sensor takes place after a defined time in the razor, the time difference between the first actuation and the last actuation is stored in the razor. This information is important. This is because the length of shaving time is proportional to the length of time of use of each razor blade and is in a reciprocal relationship with the type of hair or beard. Furthermore,
The length of shaving time is related to the personality of the user, as long as the user is typically particularly thorough and careful or swift. The age of the user and the time of shaving are also a problem and can therefore be taken into account in the course of the program in the form of characteristic values in the characteristic region. Since the characteristic domain can be renewed, the program goes through self-learning. The initial value is input by manually operating the input device 13. During the course of the program, this self-rating of the user is compared with the detected actual value and the characteristic area and the display device 12 are matched accordingly.

Upon change of the blade detected by the monitoring device 24, the variable values are automatically set to zero and the program is started anew.
