Description

Toothbrush with built-in tank and automatic dosing of toothpaste.

Introduction

The object of the present invention relates to a new type of toothbrush that incorporates a toothpaste container and has an automatic mechanism for automatic dosing of the toothpaste.

The brush itself is not a novelty because it is a brush of the usual ones in the trade that can be chosen among several that have different hardness of bristles according to the preferences of the customers depending on the sensitivity of their
gums

The novelty of the invention is focused on the incorporation of the toothpaste deposit by giving a special shape to the handle and the dosing system of said paste which, being adjustable, causes the toothpaste to flow directly to the brush and can be started without further cleaning process
teeth.

Sector of the technique to which the invention relates

The invention presented affects the Sector of Current Needs of Life, chapter of Personal Objects or Domestic with regard to objects of personal use and brushes, influencing, from an industrial point of view, the manufacture of oral hygiene articles.

Background of the invention

The toothbrush is a great item profusion in all homes to affect personal hygiene being also forced that each member of a family or group Have yours for obvious reasons. It is also very common that have more than one with different stiffness or hardness of the bristles or with characteristics suitable to be used during trips of any kind. It is meant by this that it is a item that is manufactured in the world by millions with the particularity that it has a relatively short duration so It is necessary to renew it with some frequency.

On the other hand, it is also evident that the use of the toothbrush is associated with the consumption of toothpaste so that the act of oral cleaning is effective, being without However, the pasta tube is not used up very often spare part available so that sometimes the process of Cleaning cannot be performed with desirable perfection.

Finally it must be said that the use of the same pasta tube by several members of a family can cause contagion being recommended that everyone has the yours.

The brush model object of this invention does not differs especially in what is the brush itself with the usual type of bristles and their distribution. What it is novel and characterizes the invention is, on the one hand, the existence of a toothpaste deposit forming part of the body of the brush, specifically of its handle and, on the other, the incorporation of an automatic pasta dosing system that flows directly to the brush, in the amount desired by the user at the time of starting the oral cleaning process. For this only requires turning a small wheel of striated perimeter existing at the end of the handle.

Description of the invention

The present invention, as it has remained exposed in the introduction, refers to a new type of brush dental consisting of the brush itself where the inventor does not introduce any news in terms of features and distribution of the sows, being able to consider in that sense Like a normal brush However, it does include one aspect. novel consisting in that it is designed in such a way that the paste dentifrice can reach that brush directly without the need to perform the typical operation of extending it from the classic tube of pasta Later we will return to this point of the invention.

The most important part of said invention is that about two thirds of what would be the handle of a traditional brush, is shaped like a deposit that has the shape of a revolution cylinder and which is intended to store pasta Traditional dentifrice At one end, the cylinder is closed by a kind of caster with fluted edges that, notwithstanding effect the aforementioned closure, it is capable of rotating on the axis of cylinder symmetry moving, in turn, a threaded rod in its entire length, which acting as an auger, displaces a washer fitted inside the cylinder and tension a spring which presses on a small plunger that has on its active side the toothpaste.

On the other end of the cylinder, that is, on the part closest to the brush there are holes that allow or prevent the exit of the pasta according to whether or not they are faced with exit holes that are the ones that feed the brush through of the last section of handle that is hollow.

Having made this general description, we will give some details. The screw is integral with the wheel with ribbed edges. The helical spring is conical so that, when pressed, some turns fit into others and occupy the minimum possible space. Said spring is comprised between a threaded pusher plate in the auger and the piston whose active part is in contact with the paste. If the paste has no outlet, the piston cannot move and the effect of rotating the wheel is the displacement of the pusher plate by compressing the spring. As soon as the paste is exited with a rotation (of about 60 degrees) of the brush with respect to the storage cylinder, the spring returns the deformation energy and pushes the plunger which in turn does it on the paste with which, this It flows to the brush through the last section of the handle which, as we have indicated before, is hollow. This process concludes when the spring has been fully tensioned. It is understood that the greater the energy stored by the spring, the greater the amount of paste that is supplied to the brush, which allows dosing the
product.

If the cylindrical tank is transparent it is possible to control the amount of existing toothpaste and know the time of exhaustion for replacement purposes. To do this open the tank by its base after pressure on the triggers of retention that support the cylinder-tank with Another outer protection cylinder.

The hollow part next to the brush ends branching into several ducts to properly distribute the Pasta in the bristles.

Description of a preferred embodiment

Toothbrush with built-in tank and automatic dosing of toothpaste (Figs. 1 and 2), which consists in a regular toothbrush, associated with a deposit of toothpaste storage with an associated mechanism that it allows to dose directly on the brush the amount of desired paste

In an embodiment preferred by the inventor, the toothbrush depicted in figure 2, consists of three sets shown in figure 1.

First of all the regulatory deposit is included (1) which has the shape of a straight revolution cylinder whose base bottom has a caster (2) that acts as a closure for that end of the cylinder but with the possibility of turning with respect to the same. The wheel (2) is integral with a screw (3) that  covers the entire length of the regulating tank (1) pivoting on the cover (9) that closes the other end of the cylinder. About him worm screw (3) a thrust plate (4) is mounted with a thread which, before turning the auger (3) forces the plate thrust (4) to move longitudinally inside the regulator tank (1) because said plate (4) cannot turn when conditioned by the guide (8). That is, under these conditions, a rotation of the wheel (2) and the auger (3) in solidarity with it, it transforms into a longitudinal movement of the thrust plate (4) along the axis of the cylinder. It is evident that at turns according to Wheel clock hands (2) correspond to displacements of the thrust plate (4) in one direction and counterclockwise turns of the wheel corresponds to movements in the opposite direction of the push plate.

On said push plate (4) is mounted a conical helical spring (5) whose opposite end rests on the plunger (6). Well, toothpaste (7) is stored in the space between the active face of the plunger (6) and the cover (9) which is provided with holes (10) where it can leave the pasta if nothing prevents it.

If these exit holes (10) are clogged, turning the wheel (2) causes displacement of the thrust plate (4) which, in turn, compresses the spring (5) because the piston (6) cannot move. (Pasta is supposed to be incompressible). If, under these conditions, the passage through the holes (10) a paste outlet (7) occurs during the time in which the spring (6) recovers its relaxed position. Is understood which at greater turn of the wheel (2) with holes (10) sealed corresponds more tension in the spring (6) and, consequently, greater subsequent output of paste (7), that is, that the user can dose at will the amount of toothpaste that, in your moment is released through the exit holes (10).

The second set is a protective cover (12) which, also being cylindrical, fits over the tank regulator (1) being immobilized on it thanks to the existence of two retention triggers (13) that are introduced into the traces of position (11). The protective cover (12) has other through holes (15) that are perfectly coincident with the outlet holes (10) and also has a threaded surface (14) on which the third set of this invention is coupled whose reception cone (17) is adjusted by rotating on the surface threaded (14) until it stops. The receiving cone (17) is attached to the brush (16) proper with its bristles (19), having inside, which is hollow, ducts (18) that distribute toothpaste on the basis of the bristles (19) that they are impregnated and ready for the cleaning operation dental.

This third set is designed in such a way that, in the stop position, the through holes (15) and, in consequently, the output ones (10) are sealed. To release the step of paste (7) it is necessary to turn around 60 degrees brush assembly (16) whereby the coincidence of the through holes (15) with the distribution tubes (18).

It is not considered necessary to make the content of this description for a subject matter expert can understand the scope and advantages derived from the invention, as well as develop and implement the object of the same. However, it should be understood that the invention has been described according to a preferred embodiment thereof, whereby It may be subject to change without affecting or suppose any alteration of the basis of said invention. Is say, the terms in which this description has been exposed preferred of the invention, should always be taken with character Broad and not limiting.
