Abstract

FIELD: individual sanitary and hygienic articles. SUBSTANCE: toothbrush has handle, head part with bristles, DC source and current-conductive members. First current-conductive member is electrically connected to current source positive pole and is located on handle. Second current-conductive member is connected to current source negative pole and is positioned in zone adjacent to bristles. Toothbrush is further equipped with current limiter, relay and light-emitting diode indicator, which are connected in series with current source negative pole. Current- conductive member is made in the form of metal plate. Toothbrush of such construction allows daily deposit to be removed and difficult-for-access zones of mouth cavity to be effectively cleaned. It also provides for reduction of teeth sensitivity, gum strengthening and paradontosis prophylaxis. EFFECT: simplified construction, wider operational capabilities and convenient use. 3 cl, 4 dwg

Description

 The invention relates to sanitary-hygienic accessories and can be used for the prevention and treatment of diseases of the oral cavity.

 It is known that the natural polarity of the teeth is negative. Positively charged particles and microbes adhere to the surface of the teeth, forming a plaque, and the beginning of the digestion process in the oral cavity leads to the formation of tartar. Over the years, a person changes metabolism and the condition of teeth and gums.

 When using a conventional toothbrush, it is partially possible to remove plaque from the surfaces accessible to the bristles of the brush. But the interdental space retains plaque and tartar. Which leads to caries, bleeding gums, tooth mobility, inflammatory processes in the oral cavity and causes a general deterioration of the body.

 Known toothbrush containing a handle, a head with bristles, a constant current source (RF patent 2129826, A 46 V 9/04, 1999). The power source is installed in the handle of the brush and is connected to the element that conducts current when wet.

 The use of the well-known brush does not allow to ensure sufficient effectiveness of its preventive and therapeutic effects.

 The technical effect of using the proposed solution is the higher effectiveness of the preventive and therapeutic actions, expressed in the possibility of protecting the teeth from caries, the prevention and treatment of periodontal disease, the removal of inflammatory processes in the oral cavity.

 The specified technical effect is achieved as follows.

 Toothbrush contains a handle, a head with bristles and a constant current source. The brush is equipped with two conductive elements. The first conductive element is electrically connected to the positive pole of the current source and placed on the handle. The second element is electrically connected to the negative pole of the current source and is located in the area of the bristles.

 In addition, the brush can be equipped with a current limiter, a relay, and an LED indicator connected in series with the negative pole of the current source.

 However, the conductive element can be made in the form of a metal plate.

 Due to the fact that the brush is equipped with two conductive elements, one of which is electrically connected to the positive pole of the current source and placed on the handle, and the second is electrically connected to the negative pole of the current source and located in the area of the bristles, when water enters the bristles, the circuit is closed. In the process of using the brush, the user's hand is in contact with the conductive element located on the brush handle and connected to the positive pole of the power source. At the same time, a negative charge forms on the bristles of the brush. Positively charged particles of plaque on the teeth and tartar are attracted to the bristles of the brush, cleaning the surface of the teeth and oral cavity.

 Due to the fact that the brush is equipped with a current limiter, a relay and an LED indicator connected in series to the negative pole of the current source, it is possible to select the optimal electric current strength, as well as the ability to control the state of the power source.

 The implementation of the conductive element in the form of a metal plate allows you to provide the necessary electrical contact while observing the ergonomic qualities of the product.

 Figure 1 shows a toothbrush, an electrical diagram; figure 2 shows a toothbrush in a disassembled form, figure 3 is the same, in assembled form; figure 4 - a toothbrush with a metal plate.

 The toothbrush contains a handle 1, a head 2 with a bristle 3 and a direct current source 4. The brush is equipped with two conductive elements. The first conductive element 5 is electrically connected to the positive pole of the current source 4 and placed on the handle 1. The second element 6 is electrically connected to the negative pole of the current source 4 and located in the area of the bristles 3. In addition, the brush can be equipped with a current limiter 7, relay 8 and an LED indicator 9 connected in series with the negative pole of the current source 4. However, the conductive element can be made in the form of a metal plate 10.

 As a power source 4 of the electronic circuit is used, for example, a micro-battery "Nickel / cadmium 3 V" or "Lithium 3 V".

 Toothbrush is used as follows.

 Before operation, the indicator of the power supply 4 (batteries) is checked using the LED indicator 9. To do this, close the circuit, for example, attaching a metal object with one end to the conductive element 5 (metal plate) on the brush handle 1 and the other to the contact of the conductive element 6 located in the bristle zone 3. If the LED indicator lights up, the device is ready for operation. The bristles of the 3 brushes are wetted with water. After that, the brush is used in the traditional way.

 The process that occurs in the oral cavity is based on a galvanic effect that ensures the movement of positively charged particles located on the teeth and gums towards negatively charged bristles of the brush. Thus, the removal of pathogenic particles from the oral cavity occurs.

 Using the proposed solution allows you to clean the daily plaque and hard-to-reach areas in the oral cavity, for example the interdental space, and provides a reduction in tooth hypersensitivity, strengthen gums, teeth whitening, prevention and termination of the carious process and periodontosis.
