Description

Electromechanical toothbrush

The invention relates to the field of meeting the vital needs of a person, to brush products, specifically to electromechanical toothbrushes.

Known electromechanical toothbrushes (Braim Oral-B and 11gaLp1egS1eap Combo System, Braun Oral-B Plaque Remover Replacement Brush (www.braun.com), RowentaMH-450

(www.sebgroup.ru/products/rowenta), combining from a handle with a microelectronic drive located in it, and a cleaning head, including one or two crown brushes, performing rotational ellipsoid or circular motions, reciprocating and / or oscillatory motions with a certain frequency (vibration) with a high (up to 30 kHz) frequency.

A common drawback of these toothbrushes is that the entire cleaning head or only its villi repeats the movements of a regular manual toothbrush that are not optimal for proper brushing. In all designs, there is a movement of villi from the top of the tooth to the gum and reciprocating movements along the dentition, which is very undesirable, as it loosens the interdental gingival papillae, which causes bleeding from the gums, an increase in gingival pockets and the accumulation of blood and putrefactive bacteria in them. The second drawback of these toothbrushes is the insufficient cleaning of the interdental spaces. The above designs of electromechanical toothbrushes also do not provide the desired performance, require accurate positioning of the cleaning head on the teeth, and, accordingly, increased attention to the cleaning procedure. In other words, all toothbrushes require their user to have certain knowledge and skills, the ability to clean properly

teeth, the use of an electric drive in all of these brushes is not very justified, since it does not create fundamental advantages compared to hand brushes.

The closest in technical essence is the Braun Oral-B Plaque Remover 3D electromechanical toothbrush (www.braun.com), consisting of a handle with a micro-drive located in it, a neck with a drive axis located in it, and a working head consisting of a head housing and high-frequency crown brush (3800 VMHH.)

back and forth movements.

However, this device has the following disadvantages. The small area of the cleaning element, the crown brush, reduces the cleaning performance and requires precise positioning of it on the tooth surface being cleaned and its handling skills. The villi of the brush make oscillatory movements, loosening the interdental papillae and causing bleeding from the gums. The interdental spaces are not scrubbed enough, since the villi cannot penetrate deeply into them and reliably capture food debris.

A new technical result - improving the quality and productivity of cleaning while reducing trauma to the gums and expanding the functionality of the device is achieved by using a new design of an electromechanical toothbrush, consisting of a handle with a microelectric drive located in it and a working part with a cleaning element connected to it by a drive axle, closed by a casing, moreover, the working part is made in the form of two counter-rotating cleaning elements connected to the micro-drive by parallel drive syami, zakr1t1mi casing with vneschney qTjogOHbi, also the drive axle performed moderately flexible cleaning elements as the working part are removable, as the cleaning elements are in the form of cylindrical brushes, as the cleaning elements are designed as cylindrical rollers lumpy.

The electromechanical toothbrush shown in FIG. 1. (A-view from below in section, B-view from side in section. B- front view), consists of a handle (1) with an electrical connector (7) located in it, a microelectric motor (3) and a reduction gear (4), from which two parallel counter-rotating axes (5) extend, at the ends of which there are cleaning elements (2), covered from the outside by a protective casing (6), which is a continuation of the handle (1).

Electromechanical toothbrush operates as follows. After connecting it through the connector (7) at the end of the handle to a standard power supply unit (8) with a voltage of 3-4.5 volts, the cleaning elements (for example brushes) begin to counter-rotate at the optimal frequency so that when they touch, they are in the gap between the cleaning elements. More precisely, when the brush is brought to the dentition, the cleaning elements

crawl onto the crowns themselves. At the same time, the inside and

external lateral surfaces of teeth. In this case, there is no need to make any manipulations with the brush except for smoothly moving it along the dentition. The flexibility of the rotating axes allows the cleaning elements to diverge by 3-5 mm when crawling on premolars and molars. When the brush rotates along its longitudinal axis left-right by 15-30 degrees, the cleaning elements also clean out the chewing surfaces of the teeth. With the gradual advancement of the brush along the dentition, the entire oral cavity is cleaned. It is not necessary to press the brush to the teeth. You can simultaneously brush the external (labial and buccal) surfaces of the teeth on the upper and lower jaw by turning the brush horizontally so that one cleaning element touches the upper teeth and the other lower ones. In this case, a slight clamping of the cleaning elements to the surface of the teeth is required. During the cleaning process, the protective cover prevents the contact of the rotating cleaning elements with the mucous membrane of the oral cavity, preventing its trauma and making brush handling safe. Variants of the arrangement of the cleaning elements of the working part are shown in FIG. 2.

The proposed electromechanical toothbrush allows you to increase the productivity and effectiveness of the procedure for brushing your teeth, without causing damage to the gums and without loosening the interdental papilla. It is fundamentally important that the brush automatically provides the most correct brushing of the teeth, without requiring special skills from the user, the ability to brush teeth. Brush hair moves during brushing only from the gums to the tops of the teeth. There are no reciprocating vertical or horizontal movements that loosen the interdental papilla and cause bleeding from the gums. This is unattainable when using both manual toothbrushes, and all known electromechanical. Thanks to the proposed principle of counter-rotation of the cleaning elements, the brush perfectly cleans the interdental spaces, cleans the crown of the tooth at the same time as the outer and inner sides, pulling out the remnants of food between the teeth. The softness of the cleaning elements, combined with the ease and even pleasantness of the cleaning procedure, allows you to brush your teeth for a long time (3-4 minutes), while doing a gum massage. Even with a brief cleaning procedure (20-30 sec.), Its quality is very high, since the brush performance is several times higher, due to the simultaneous cleaning of two or three teeth on both sides, which is unattainable for all known designs of electromechanical toothbrushes.

To expand the functionality of the proposed electromechanical toothbrush CLEANERS, the elements are removable, which allows them to be replaced when worn and dirty. Cleaning elements can be replaced with massage tuberous rollers with different surface patterns. In this case, the brush is used as a gum massager, which allows you to fight gingivitis and periodontosis.

Brush tests were conducted on 10 volunteers, of which 6 people increased gum vulnerability. All of them used a toothbrush of the proposed design for one month every morning and evening for 2-3 minutes.

Tests have shown that people like the simplicity of the cleaning procedure itself and the fact that the brush does not cause the slightest bleeding from the gums. All noted the high quality of cleaning the interdental spaces and how well the brush pulls out food debris even from unsealed hollows (2 people). Two people noted that a somewhat unusually soft brush brushes the back teeth. There is no sensation of the procedure, but the cleaning quality is excellent. Everyone liked the feeling of brushing their front teeth. My family members (me, wife and son) have been brushing their teeth for about 6 months now and are very happy with it. The brush allows you to save the paste by quickly creating a voluminous foam in the oral cavity, and to exclude pastes with high abrasiveness from use, which reduces the abrasion of tooth enamel during brushing. The elemens are easy to clean while rotating. With prolonged use of the brush as a gum massager, the signs of gingivitis disappear even without the use of medications.
