The inner valve (32) is contacting the inner part of the hollow mandrel (31) and the outer part of the hollow mandrel (31) is in contact with the other end of the inner passable duct (11), wherein transfer of the cleaning medium from the inner bag (33) to the hollow mandrel (31) is secured when the inner valve (32) is depressed, and further, the cleaning medium container (3) at its other end is in contact with the button (4), wherein movement of the cleaning medium container ( 3) in the direction of the hollow mandrel (31) is controlled by the push-button (4).

Description

Title: Toothbrush with internal filling
Field of the invention
The invention relates to a toothbrush with an internal container of cleaning medium (toothpaste), which is through a pressure system transported on the head of the toothbrush with bristles and rubber outlet with a simple way of cleaning.
Background art
At present, several valid or no longer valid protections for various types of toothbrushes are known. These are mainly different types of brushes of the classic type without a container with cleaning medium consisting of a handle of different ergonomics and sizes ended with a head with a set of bristles. For these solutions, it is always necessary to apply the cleaning medium (toothpaste) from a separate tube that is not filled in the inner brush container. These solutions or toothbrushes without internal filling are a proven solution in households where it is not a problem to have the toothbrush separate from the cleaning medium (toothpaste). In the case of travel use, this solution is no longer practical.
During the research it was found that there are also invalid utility models describing brushes with internal filling. However, in the above-mentioned screw-based mechanism solutions, the solution is outlined in such a vague or technically impracticable manner that in practice it would not be possible to produce such internally-filled toothbrushes. Other solutions found disclose brushes with an inner container that is based on a container with a cleaning medium (toothpaste) pressurized with an aerosol. Such a solution is quite demanding from a technical point of view and it is also necessary to use only custom-made aerosol canisters.
The disadvantage of current solutions is, above all, insufficient sizing of the internal mechanism, whose components often last only a few applications. A further disadvantage of the known solutions is the drying of the cleaning medium (toothpaste) in the orifices on the brush head and in some cases also directly inside the entire mechanism. Disclosure of the invention
Above mentioned disadvantages are removed by an inner-filling toothbrush consisting of a cleaning part having an internal passable duct for the conducting the cleaning medium flowing at one end into the bristle surface, where the cleaning part is connected to a handle according to the present invention, wherein the handle contains at least one pressure container with at least one inner bag containing a cleaning medium. The pressure container is in contact with at least one inner valve, and the inner valve is in contact with the inner part of the hollow mandrel and the outer part of the hollow mandrel is in contact with the other end of the inner passable duct. The transfer of the cleaning medium from the inner bag to the hollow mandrel is ensured when the inner valve is compressed. The cleaning medium container at its other end is in contact with the button, when the movement of the container towards the hollow mandrel is controlled by the button.
It is expedient for the passable duct opening into the bristle surface to be terminated by at least one orifice, in a preferred embodiment the orifice is adapted to prevent air from entering the duct.
Preferably, the cleaning part and the handle are releasably connected.
It is expedient for the cleaning part to be provided with a protective cover, and it is further preferred that the cleaning part is provided with a guide rail.
The advantage of this technical solution can be seen mainly in the ease of use, low production, relatively simple construction, and corresponding costs of purchase.
Description of the drawings
Figure 1 shows the brush in longitudinal section including the outer packaging.
Example of embodiment of the invention
The toothbrush with internal filling consists of the cleaning part 1_and the handle 2. In a preferred embodiment, the cleaning part 1_and the handle 2 are releasably connected to each other, for example by means of a screw connection or a snap system. The cleaning part 1_is provided with an internal passable duct 11 for conducting the cleaning medium, which leads at one end into the bristle surface 12 and at the other end it is in contact with the outer part of the hollow mandrel 31. The cleaning part ljs connected to the handle 2, the handle 2_contains at least one cleaning medium container 3. The cleaning medium container 3js preferably presented as a cartridge containing an inner bag 33 which is filled with the cleaning medium, wherein the cleaning medium is stored in the cartridge under pressure. The cleaning medium container 3js provided with at least one internal valve 32 which is in contact with the inner part of the hollow mandrel 3JL The transfer of the cleaning medium is provided upon contact of the inner part of the hollow mandrel 31 with the inner valve 32. The outer part of the hollow mandrel 31 is fitted to the other end of the inner passable duct V\_. Cleaning medium container 3 is at its other end in contact with the button 4, wherein the movement of the container 3 of the cleaning medium in the direction of the hollow mandrel 31_is controlled by the button 4.
To ensure hygienic cleanliness of the passable duct 1_1, the passable duct U isprovided with at least one orifice 13, where the orifice 13_is configured as a hemisphere comprising at least one cut. In a preferred embodiment, the cuts are cross-shaped.
To ensure hygiene, cleaning part IJs provided with a protective cover 5, for example a transparent plastic cover, which is by sliding connected to the handle 2. It is further preferred that the cleaning part 1_is provided with a guide bar 6_to reduce the bending stress and thereby increase the strength.
The toothbrush with internal filling according to this invention is adapted for dental hygiene. By pressing the button 4, the user moves the cleaning medium container 3_towards the cleaning part 1. The cleaning medium container 3js thereby moved in the direction of the hollow mandrel 31 and by being firmly anchored in the inner channel JM , it is deflected and pushed on the inner valve 32 and the cleaning medium is transferred from the cleaning medium container 3. The cleaning medium passes through the hollow mandrel 31 through the inner duct 1 1 to the bristles 12 on the head of the cleaning part 1 The orifice 13_is opened by the pressure of the cleaning medium. By releasing the button 4, the dosing process is stopped and the orifice 13 closes again, thereby preventing air from entering the internal passable duct V\_.
Thus, the brush is provided with a cleaning medium and can be performed by the user by oral hygiene.
In case the container 3_of the cleaning medium is empty, it is possible to alternatively use a new toothbrush. Or if the cleaning part 1_and the handle 2_are releasably connected together, it is possible to replace the entire cleaning medium container 3_with a full one. industrial applicability
The toothbrush with internal filling of cleaning medium (toothpaste), which is transported through the pressure mechanism to the head of the bristle brush, is designed to provide dental hygiene especially in case of travel and business trips of the user .
