Definitions

  • the present invention relates to a toothbrush according to the preamble of claims 1 and 2.
  • Periodontitis is the gradual destruction of the tooth structure. Both diseases are caused in particular by bacteria that nest between the teeth, which form acids and toxins in the long chain of their decomposition. Therefore prophylaxis, which is accessible to everyone and easy to use, is given in and of itself.
  • a tooth-specific healthy diet is certainly the first prophylactic measure: By reducing the sugar supply, the bacterial growth and consequently the formation of acids and toxins can be minimized. Now it is hardly possible to completely dispense with sugar intake in everyday life. If you wear them Taking this fact into account, oral hygiene is the most important factor in combating caries and periodontitis. The regular removal of food residues prevents the proliferation of bacteria and thus on the one hand the formation of acids and on the other hand the gum irritation due to dead bacteria, which is dangerous for periodontitis. A tooth brushing of at least two minutes after each main meal is to be considered optimal.
  • the invention seeks to remedy this.
  • the invention is based on the object of proposing a toothbrush, the use of which makes it considerably easier for the toothbrushing to comply with the minimum period of time recommended prophylactically against caries and periodontitis. On the one hand through a time objectification, on the other hand through the fact that this period of time is made sensitive and pleasant.
  • the main advantages of the invention can be seen in the fact that the desired goal can be achieved without the aid of external aids.
  • actuating a capacitive or inductive switch placed in the handle part of the toothbrush which according to a preferred embodiment of the invention lies at the thumb level of a conventional toothbrush handle, the means housed there and preferably combined into a single module are activated, that a melody and / or linguistic texts of any kind Be emitted.
  • the emission duration corresponds to the period of time that is considered by dental science as the optimal period for brushing teeth after each main meal, namely two minutes each.
  • visual signals can be generated, which could be particularly advantageous for the hearing impaired.
  • a further advantage of the invention can be seen in the fact that the time of the change of the toothbrush, which is necessary for hygienic reasons, and which is not so much to be seen with the consumption of the bristles, but primarily with the risk of transmission of bacteria growing on the bristle part, is unmistakably through Failure to signal the emission is signaled.
  • the battery has three months of autonomy when used twice for two minutes each day, i.e. the lifespan that dental science expects to replace the toothbrush.
  • the agents are commercially available elements, so that from an economic point of view, the toothbrush is easily disposable.
  • toothbrushes can be programmed with various melodies and / or linguistic texts, such as instructions, messages, entertainment, etc.
  • the purchase of a new toothbrush offers the opportunity to choose a new melody or type of emission.
  • the toothbrush can easily be designed so that the bristle part can be replaced.
  • the clip-on and disposable bristle part contains the battery.
  • the bristle part can also be driven electrically, which facilitates and intensifies tooth brushing.
  • toothbrush which consists essentially of bristle part 1 and handle part 2, is supplemented with means which emit acoustic signals in the listening area of the human ear.
  • the issue can be a melody or linguistic texts, such as accompanying instructions about brushing your teeth, mini language courses, etc.
  • the emitting means of the example shown here are chip 3, battery 4, sound generator 5, sound amplifier 6 and switch 7.
  • the chip 3 By actuating the capacitive or inductive switch 7, the chip 3 is supplied by the battery 4.
  • the chip 3 programmed for a specific emission feeds its signals to the sound generator 5. If it is a piezo sounder, it consumes a current of 1.5 V 0.1 mmA.
  • the pulses from the chip 3 are in the - converted sound generator 5 into signals which produce a melody or language texts in their sequence.
  • the sound generator 5 is connected to a sound amplifier 6.
  • the handle part 2 of the toothbrush can also serve as a sound amplifier.
  • He NATURALLY l i ch is easy to expand to an adjustable element, in particular so-appears when the bristle part 1 is electrically driven. In such a case, the setting could be carried out, for example, via a now rotatable switch 7.
  • a "timer" is installed in chip 3, which is preferably set to a pulse duration of two minutes. Of course, an individually adjustable pulse duration can also be provided here.
  • the battery 4 has an autonomy of three months when the toothbrush is used twice for two minutes each day. This lifespan corresponds to the use of a toothbrush recommended by dental science. This clearly signals when the time has come to replace the toothbrush.
  • the means 3,4,5,6,7 are commercially available elements. It is possible to assemble them into a single modular building block in the form of a rondelle, the overall dimension of which according to the current state of the art is approximately 15 mm in diameter and approximately 2-4 mm in thickness. Such a rondelle can thus be easily accommodated or attached to the handle part 2, be it with the manufacture of the toothbrush or afterwards.
  • the switch 7 is placed at the thumb level of a conventional toothbrush handle; a practical switch-on can already be achieved by gripping the toothbrush.
  • the bristle part 1 can be designed interchangeably. This will always be indicated if it is part of an electrically powered toothbrush. Then it's obvious enough that the bristle part 1 is supplemented with the battery 4 when the toothbrush is not electrically driven, thus optimizing the disposability of the two consumable parts.
  • Fig. 2 shows a toothbrush similar to that of Fig. 1. The difference is that this toothbrush is designed for visual signals.
  • the means here are a battery 4, a timer 3a, a switch 7 and a light source 8 integrated in the switch 7.
  • the mode of operation and the advantages are the same as those described in FIG. 1.
  • the switch 7 When the switch 7 is actuated, the light source 9 lights up and emits light as long as the set or adjustable time period lasts.
