Description

Oral care equipment with dental plaque detects

Technical Field

The present invention relates to personal care devices, and more particularly to oral care devices.

Background

Teeth are important parts of human body, and have the following functions of 1 chewing food, 2 beautifying face and 3 assisting pronunciation. The dental diseases not only weaken and even lose the functions of teeth, but also cause gastrointestinal digestive system diseases such as chronic enteritis, intestinal tuberculosis and the like, and systemic diseases such as diabetes, headache, arthritis, rheumatic heart disease, myocarditis, bronchitis, sphagitis and the like. The health of the teeth can greatly affect the quality of human life associated with health.

Dental plaque is a soft, unmineralized bacterial population that is either matrix-wrapped, adheres to each other, or to the surface of the tooth, interdental, or restorative surfaces, and is a bacterial biofilm that cannot be washed away or rinsed away with water. Dental plaque constitutes a major hazard to the teeth and gums, two of the most common diseases of the oral cavity: caries and periodontal disease. Caries is commonly known as "caries" where the "worm" refers to bacteria in the plaque. Plaque adheres firmly to the tooth surface, and the bacteria ingest the sugars in the saliva, breaking down the sugars and producing acids, which can damage the teeth and eventually create cavities. When plaque is near the gums, toxins and other harmful substances produced by the bacteria can irritate the gums (commonly referred to as "gums") and cause inflammation, i.e., gingivitis. Without treatment by a professional dentist, gingivitis may develop into irreversible periodontitis, causing destruction of the alveolar bone, eventually resulting in loosening and loss of teeth.

The prior art detection of dental plaque is to first illuminate with an illuminating device, detect the surface state of teeth by naked eyes, and then clean the found dental plaque with a dental cleaning device. The prior art has the following problems in practice:

1. the detection means is separated from the cleaning means, and after dental plaque of the tooth is detected by naked eyes using the illumination means, the dental plaque is then cleaned using the cleaning means. When cleaning device is used to clean dental plaque, cleaning device has blockked the light that lighting device sent for cleaning device can not pinpoint the dental plaque, does not reach the purpose of complete clearance dental plaque.

2. The light emitted from the illumination device of the detection device is white light, and when the amount of dental plaque is small, it is difficult to observe the dental plaque by the naked eye by the illumination of the white light.

Therefore, it is desirable to have a household plaque detecting and cleaning device that combines an illumination device and a cleaning device, and that can emit violet light, indicate and locate plaque, clean plaque at the same time, and achieve the goal of early detection and treatment.

Referring to fig. 1-5, the present invention provides an oral care device with plaque detection, comprising: the dental plaque cleaning device comprises a body 1, an oral cavity cleaning component 3 and a dental plaque detection component 2, wherein the oral cavity cleaning component 3 and the dental plaque detection component 2 are arranged on the body 1;

the dental plaque detection assembly 2 comprises an LED chip 21, a filter 22, a camera assembly 23 and a main control chip 24; the LED chip 21 is used for emitting purple light to teeth; the filter 22 is arranged at the front end of the light inlet surface of the camera component 23, and the filter 22 is used for receiving autofluorescence generated after the teeth are irradiated by purple light and filtering light with the wavelength of 420nm-500 nm; the signal input end of the main control chip 24 is connected with the camera, and the signal output end is connected to the intelligent terminal device.

In the oral care equipment with dental plaque detection, the LED emits 405NM wave band light to be projected on the tooth surface; the dental plaque on the tooth surface is excited by wave bands to generate autofluorescence (containing light of various wave bands), and the autofluorescence enters the camera assembly 23 after the light with the wavelength of 420-500nm is filtered by the filter 22, so that the dental plaque part is red and the healthy teeth are green. Thereby realize that oral care equipment has the plaque and detect the function, the user just can regularly check the tooth condition of oneself, need not to purchase new equipment or go to oral hospital, has practiced thrift user's time and money. And because this oral care equipment can show the position of dental plaque in real time, also make things convenient for the user to carry out focus when carrying out oral care to there is dental plaque to clean.

In this embodiment, LEDs with three wavelengths are selected for the comparison experiment, the wavelength of the first group of LED chips 21 is 405nm, and the brightness is 450 lumens. The second group of LED chips 21 has a wavelength of 435nm and a brightness of 450 lumens. The third group of LED chips 21 has a wavelength of 435nm and a brightness of 400 lumens. The wavelength of the violet light is 405nm.

Respectively shooting dental plaque display effect videos in the same environment by using the dental plaque detection assemblies 2 with the three specifications; it can be seen from the captured video that the second group of plaque is vivid but confusing, and the first group of plaque is inferior in color to the second group but is sharp in contrast. Thus, the plaque detection assembly 2 is selected for this embodiment to have a wavelength of 405nm and a brightness of 450-800 lumens.

In this embodiment, the oral cleaning component 3 is a water dental floss, and therefore, the body 1 is internally provided with a water tank 11 and a pulse system 12; the pulse system 12 is connected between the oral cleaning assembly 3 and the water reservoir 11. The water in the water tank 11 can be pumped out by the pulse system 12 and pumped into the water outlet nozzle of the water dental floss to be sprayed. This achieves the flossing effect. The pulse system 12 can be realized by a motor driving a piston to move, which belongs to the prior art, and the embodiment does not perform too much expansion.

In the present embodiment, in order to achieve the water dental floss effect and to photograph dental plaque, the water outlet nozzle and dental plaque detection assembly 2 is provided at an upper end surface of the body 1 in the height direction. And, the dental plaque detecting assembly 2 is provided at a side of the spout close to the user in a width direction of the body 1. This avoids the nozzle obstructing the plaque detecting assembly 2.

The body 1 is provided with a power key 13 and a mode selection key 14; the mode selection button 14 is used for adjusting the water outlet strength of the oral cleaning component 3. Specifically, when the power key 13 is pressed for a short time in the power-off state, the power is turned on, and after the power is turned on, the mode of the short-mode selection key 14 is adjusted (in this embodiment, the three modes are adjustable, and are strong, medium, and soft according to the water outlet strength), after the power is turned on, the power key 13 is pressed for a short time, the pulse system 12 is started to form pulse water, and when the pulse system 12 is started, the power key 13 is pressed for a short time, the motor is turned off, and the mode of the long-mode selection key 14 is pressed for a long time, the mode is adjusted again.

The above, only be the preferred embodiment of the present invention, but the design concept of the present invention is not limited to this, and any skilled person familiar with the technical field is in the technical scope disclosed in the present invention, and it is right to utilize this concept to perform insubstantial changes to the present invention, all belong to the act of infringing the protection scope of the present invention.
