Description

The invention relates to the field of sanitary-hygienic supplies and can be used for caring for the oral cavity and cleaning deposits of various origin formed in the process of human life on the surface of the teeth and tongue.

A device for caring for the oral cavity, containing a scraper for cleaning the tongue, mounted on a non-metallic strip mounted with the possibility of telescoping from the cavity, made in the handle of the device (UK patent No. 2252909, class A 46 B 15/00 from 1992) .

The implementation of the device with a movable element complicates the design, and the presence of a closed cavity complicates the hygienic cleaning of the device itself, which can lead to the introduction of unwanted flora into the oral cavity of the user and lead to the opposite of the desired result.

A device for caring for the oral cavity, containing a handle and made in one piece with her head, on the front surface of which is fixed a bristle, and on the free end of the handle is made a flat blade of a rounded shape, curved relative to the vertical axis of the handle at an angle of at least 30 degrees (Utility Model of the Russian Federation No. 12771, class A 46 B 15/00 of 07/09/99).

The known device allows the cleaning of teeth and tongue. It provides the possibility of easy cleaning after carrying out the sanitary treatment of the oral cavity, but the effectiveness of using it to clean the tongue is not high enough, since there is no pointed edge on the shoulder blade.

The closest in technical essence and the achieved result to the proposed device is a device for caring for the oral cavity, containing a body formed by the head and handle with an outer surface including the front section, the back section and the transition sections connecting them, a toothbrush in the form of bristles fixed on the front surface of the head surface, and a scraper with a sharp edge for cleaning the tongue (patent of the Russian Federation No. 2113155, A 46 B 9/04 from 06/20/98).

The known device provides high-quality cleaning of teeth and tongue. The scraper in the known device is fixed on the handle of the toothbrush by means of a detachable connection, which complicates its design. In addition, the sharp edge of the scraper is located on the element, broadened relative to the handle, and directed perpendicular to the longitudinal geometric axis of the handle. This form of the scraper determines the cleaning of the tongue by applying a scraper with a sharp edge to the user's tongue and moving the scraper along the tongue in the longitudinal direction relative to the brush handle. However, the human oral cavity narrows toward the throat and the shape of the scraper, widened relative to the handle, does not allow reaching the base of the user's language. Thus, the language cleaning zone when using the known device is limited by the design and shape of the scraper.

The technical result from the use of the invention is to increase the efficiency of hygienic treatment of the oral cavity of the user by expanding the area for cleaning the tongue while simplifying the design and reducing material consumption.

The specified technical result is achieved in that in the device for caring for the oral cavity containing the body formed by the head and handle with the outer surface including the front section, the back section and the transition sections connecting them, a toothbrush in the form of bristles attached to the front surface section heads, and a scraper with a sharp edge for cleaning the tongue, the body of the device is integral with the scraper, and the sharp edge of the scraper is located on the body, formed by the intersection line of one of the transition sections with you nym portion of the outer surface of the body and is directed predominantly along the body.

In this case, a sharp edge can be placed on the head.

In addition, the device can be made with an additional sharp edge symmetrical to the sharp edge of the scraper relative to the longitudinal geometric axis of the body and formed by the line of intersection of another transition section with the rear section of the outer surface of the body.

The back of the head can be made flat.

The back portion of the head can be made with a recess.

Deepening the back of the head can be performed with a cross section of a predominantly curved shape.

Deepening the back of the head can be made in the form of a prism.

The transition section of the outer surface of the body, forming a sharp edge in the head area, can be made in the form of a longitudinal groove.

The oral care device may be provided with a second additional sharp edge located at the free end of the handle, directed along the body and formed by the line of intersection of the back and transition sections of the outer surface.

The oral care device may be provided with a third additional sharp edge located symmetrically to the second additional sharp edge relative to the longitudinal geometric axis of the body.

The oral care device may be provided with a fourth additional sharp edge located at the free end of the handle, directed along the body and formed by the line of intersection of the front and transition sections of the outer surface.

The oral care device may be provided with a fifth additional sharp edge located symmetrically to the fourth additional sharp edge relative to the longitudinal geometric axis of the body.

A sharp edge in the oral care device can be made along the entire length of the body from the back of the outer surface.

The invention is illustrated by drawings.

Figure 1 presents a General front view of the device (from the front side of the outer surface of the body).

Figure 2 shows a side view of the device.

Figure 3 shows a rear view of the device (from the back of the outer surface of the body).

On Fig shows a cross section of the handle, showing one of the possible options for the implementation of the scraper.

The oral care device comprises a body 3 formed by the head 1 and handle 2. The outer surface of the body includes a front section 4, a rear section 5 and transitional sections 6, 7 connecting them. The device contains a toothbrush 8 in the form of bristles attached to the front a portion of the surface of the head, and a scraper with a sharp edge 9 of the scraper for cleaning the user's tongue. The body 3 of the device and the scraper are a single unit. The sharp edge 9 of the scraper is located on the head 1, is formed by the line of intersection of the transition section 6 with the rear section 5 of the outer surface of the body 3 and is directed mainly along the body 3. The device for caring for the oral cavity can be made with an additional sharp edge 10 symmetrical to the sharp edge 9 of the scraper relative to the longitudinal geometric axis of the body 3 and formed by the line of intersection of another transition section 7 with the rear section 5 of the outer surface of the body 3.

Obtaining the above technical result can be realized by giving different forms to the front, back and transitional sections of the outer surface of the body.

For example, embodiments of the shape of the outer surface of the body are given, which cannot be considered an exhaustive list. So, figure 4 shows a cross section aa of figure 1, in which the rear portion 5 of the head 1 and the transition sections 6, 7 are made flat. In Fig. 5, the cross-section AA in Fig. 1 is represented by the execution of the back portion 5 with a curved indentation and flat transition sections 6, 7. Fig. 6 shows the cross-section AA in Fig. 1, on which the back portion 5 of the outer surface body 3 is made with a deepening of a trapezoidal shape. In Fig.7, the cross section aa in Fig.1 is shown in the execution of the back portion 5 of the outer surface of the body 3 with a curved indentation and transition sections 6, 7 with longitudinal grooves curved in the cross section. Greater cleaning of the user's language can be realized if additional sharp edges 11, 12, 13, 14 are placed on the free end of the handle 2 of the device. All of the above surface shapes, providing sharp edges on the head 1 of the device, can be implemented for the same purpose and with respect to the free end of the handle 2 (section BB in FIGS. 1 and 8).

Thus, the device can be provided with a second and / or third additional sharp edges 11, 12 located at the free end of the handle 2, directed along the body 3 and formed by the intersection lines of the back section 5 and the transition sections 6, 7 of the outer surface of the body 3. The second and the third additional sharp edges 11, 12 are located symmetrically relative to the longitudinal axis of the body 3 of the device.

The device can be made with the fourth and / or fifth additional sharp edges 13, 14 formed by the intersection lines of the front section 4 and the transition sections 6, 7 of the outer surface of the body 3, respectively.

To brush teeth, the user, holding the handle 2, inserts the device into the oral cavity, puts the bristles of the toothbrush 8 on the cleaned surface of the teeth and moves the brush along or across the geometric axis of the handle 2.

To clean the tongue, the user expands the device introduced into the oral cavity in such a way that the body 3 of the device located along the tongue is in contact with the surface of the tongue being cleaned with one or two sharp edges 9, 10, 11, 12, 13, 14 located on the head or free end of the handle. Scraping of deposits from the cleaned surface of the tongue is carried out by moving the sharp edges 9, 10, 11, 12, 13, 14 in the direction perpendicular to the longitudinal geometric axis of the device body.

Toothbrush 8 and all sharp edges 9, 10, 11, 12, 13, 14 are located on the outer surface of the body 3 of the device and are available for cleaning after use without the use of special tools and devices.

In addition, the proposed cross-sectional shapes of the head 1 provide an economical use of the material spent on the manufacture of the body 3 of the device, since the same array is used to seal the bases of the brush bristles of the toothbrush and fasten the sharp edges of the scraper.
