Referring to fig. 1-6, the present embodiment provides an electric toothbrush, which includes a brush head 100, a brush handle 200, and a camera assembly 300 for image acquisition.

The camera assembly 300 includes a camera 310, a motherboard 320, and a flat cable 330. The flat cable 330 electrically connects the camera 310 and the motherboard 320 for data transmission. The camera 310 is a miniature camera with smaller volume, and is arranged at the head of the brush holder 200 for shooting and imaging.

Image data photographed by the camera 310 is transmitted to the main board 320 through the flat cable 330, and the main board 320 stores image information and controls the camera 310. In this embodiment, the main board 320 is disposed at a middle position of the brush holder 200 (in some possible embodiments, the position of the main board 320 may be a lower or bottom position of the brush holder 200, which is not limited herein); one end of the flat cable 330 is connected with the camera 310, and the other end of the flat cable extends downwards along the length direction of the brush handle 200 to be connected with the lower main board 320.

In some possible embodiments, the camera module 300 further includes a communication module for interacting with an external communication terminal. The communication module is electrically connected to the motherboard 320. The communication module can be a WIFI chip or a Bluetooth chip, and the external communication end can be a mobile phone or a computer. The WIFI chip or the Bluetooth chip transmits the acquired image information to the mobile phone or the computer for the user to watch.

Handle 200 is removably coupled to head 100. The camera 310 is positioned in the cavity of the handle 200 such that when the brush head 100 is coupled to the handle 200, the brush head 100 seals against the camera 310.

Referring to fig. 3-4, in some embodiments, the head of handle 200 is formed of two parts, handle cover 210 and handle housing 220, with handle cover 210 and handle housing 220 enclosing to form a cavity within handle 200. The position of the camera 310 in the corresponding cavity on the surface of the handle cover 210 protrudes outwards, so that the placement space for the camera 310 is increased, and the whole structure of the electric toothbrush is more compact.

A first card slot 120 is provided along the periphery of the head of the handle housing 220. The brush head 100 has a bottom plate and an annular sidewall disposed around the back of the bottom plate, the annular sidewall has a notch, and a first protrusion 110 matching the first slot 120 is disposed along the inner sidewall of the annular sidewall. In the present embodiment, the first clamping groove 120 and the first protruding portion 110 are U-shaped, but in other embodiments, the shape is not particularly limited.

In some embodiments, a second clamping groove 230 is further provided on the bottom plate of the brush head 100, and a second protruding portion 240 is provided on the front surface of the brush holder 200 corresponding to the position of the second clamping groove 230. In the present embodiment, the second clamping groove 230 and the second protruding portion 240 are elliptical, but in other embodiments, the shape is not particularly limited.

When a user needs to clean teeth using the electric toothbrush, the head of the brush holder 200 is inserted into the brush head 100 from the notch, and at this time, the first clamping groove 120 is clamped with the first protruding part 110, and the back surface of the head of the brush holder 200 is pressed, so that the second clamping groove 230 is clamped with the second protruding part 240, thereby tightly connecting the brush holder 200 with the brush head 100. The electric toothbrush now looks like a normal electric toothbrush in that the camera 310 is in the closed space formed by the combination of the brush head 100 and the handle 200 to prevent the camera 310 from being damaged by bruising or water inflow.

When a user needs to use the electric toothbrush to photograph the inside of the oral cavity, the brush head 100 is taken off the brush holder 200, the camera 310 is exposed, and the head of the brush holder 200 is extended into the oral cavity to photograph the inside of the oral cavity. Because the brush head 100 is taken down before shooting, the problem that the brush hair on the brush head 100 shields the camera 310 is fundamentally solved, so that the image shot by the camera 310 is clearer.

The electric toothbrush protects the camera 310 by modifying the brush head 100 and utilizing the structure of the brush head 100, and reduces the material cost (without adding components for protecting the camera 310).

Referring to fig. 1 again, the handle 200 is a hollow structure, and the hollow structure forms a cavity. A body mount 400 is disposed in the cavity and a power supply (not shown) is provided for powering the camera 310 assembly, which may be a lithium ion battery.

A camera hole 250 is formed in the handle 200 at a position corresponding to the lens 311 of the camera 310, the camera 310 photographs the outside of the handle 200 through the camera hole 250, and the camera hole 250 is communicated with the cavity.

In some embodiments, the camera 310 is entirely within the cavity of the handle 200, and there is a space between the highest point of the lens 311 of the camera 310 facing the side of the brush head 100 and the outer surface of the handle 200, such that the lens 311 is lower than the outer surface of the handle 200, the space length ranges from 0.1 to 0.5 mm, for example, the space may be 0.15 mm, 0.2 mm, 0.3 mm, etc. I.e., the outer surface of the handle 200 is recessed at the place where the camera 310 is provided, as viewed from the outside, to form a through hole. The distance between the lens 311 of the camera 310 and the surface of the brush holder 200 is provided to prevent the inner wall of the brush head 100 from rubbing against the lens 311 of the camera 310 when the brush head 100 is inserted into and pulled out from the head of the brush holder 200, resulting in the lens 311 being ground.

Referring to fig. 5, in this embodiment, the camera hole 250 is a tapered through hole with a circular cross section, and is disposed concentrically with the lens 311 of the camera 310, and the tapered through hole increases from a tapered aperture near one end of the camera 310 to a tapered aperture far from one end of the camera 310. I.e. the conical surface of the camera hole 250 forms a bell-mouth like shape together with the lens 311 of the camera 310. The smallest area of the cross section of the conical surface is the position where the camera hole 250 is connected with the lens 311 of the camera 310.

An included angle is formed between the lens 311 of the camera 310 and the conical surface of the camera hole 250, and the included angle is an obtuse angle. The included angle is preferably in the range of 120 ° to 180 °, for example, the included angle may be 125 °, 130 °, 176 °, etc.

In some possible embodiments, a transparent protective lens is further disposed on the side of the image capturing aperture 250 that is adjacent to the external environment. The protective lens is used to protect the camera 310 when the camera 310 is taking a picture (when the brush head 100 is removed). The protective lens is formed of non-hydrophilic glass or transparent plastic, and is preferably designed in a spherical shape so as to facilitate water to slide along the outer surface of the protective lens, thereby maintaining the stable operation of the camera 310.

Referring to fig. 6, in the present embodiment, a light emitting component 600 is disposed in the brush holder 200, and the light emitting component 600 is used for providing illumination for the camera 310 when the camera 310 performs image capturing, so that the brightness of the captured image is higher.

Specifically, the light emitting assembly 600 includes two parts, one is a light emitting element 610 for providing illumination, and one is a lens 620 for scattering light and increasing a light emitting area of the light emitting element 610. The light emitting element 610 may be an LED lamp and the lens 620 may be a fresnel lens.

The light emitting element 610 is disposed in the cavity of the handle 200, and the lens 620 is disposed on the surface of the handle 200 and is correspondingly disposed directly above the light emitting element 610 to enclose the light emitting element 610. Wherein the edge of lens 620 is flush with the surface of handle 200 to form a continuous plane on the surface of handle 200; thereby making the surface of the handle 200 look fault-free, compact, and also preventing water from entering the cavity.

In this embodiment, the brush head 100 includes a groove-shaped member 130 and bristles planted outside the groove-shaped member 130. The channel member 130 in some embodiments half wraps the head of the handle 200. The first protruding portion 110 and the second clamping groove 230 are both arranged on the groove-shaped member 130, and the groove-shaped member 130 is clamped with the head of the brush holder 200 and covers the camera 310; the channel member 130 forms a closed space with the head of the handle 200 to accommodate the camera 310. Accordingly, the groove-shaped member 130 can shield the camera to protect the camera 310.

In summary, the electric toothbrush has the following beneficial effects: the electric toothbrush has the advantages that the electric toothbrush has the functions of image acquisition and tooth brushing by arranging the camera 310; when the electric toothbrush is used for brushing teeth, the brush head 100 and the brush handle 200 are combined, so that the electric toothbrush is a common electric toothbrush from the external view; when the electric toothbrush is used for shooting an image in the oral cavity, the brush head 100 is taken off the head of the brush handle 200, the camera 310 is exposed, and the head of the brush handle 200 is extended into the oral cavity to shoot the interior of the oral cavity; the electric toothbrush reforms the brush head 100, protects the camera 310 by utilizing the structure of the brush head 100, reduces the material cost (without adding a component for protecting the camera 310), and prevents the camera 310 from damaging or damaging due to water inflow. Before shooting, the brush head 100 is removed, so that the problem that bristles on the brush head 100 shield the camera 310 is fundamentally solved, and the image shot by the camera 310 is clearer. Moreover, by arranging the detachable brush head 100, the brush head 100 can be conveniently replaced by a user, and the service life of the electric toothbrush is prolonged.

Example two

In some embodiments, an electric toothbrush is provided for image acquisition and tooth cleaning, this embodiment being an equivalent replacement made on the basis of embodiment one, this embodiment differs from embodiment one in that:

in some embodiments, the edge of the lens 311 of the camera 310 is flush with the surface of the handle 200 to form a continuous plane; thereby making the surface of the handle 200 look fault-free and compact.

In some possible embodiments, the edge of the lens 311 of the camera 310 is flush with the surface of the handle 200 to form a continuous arc.

In some possible embodiments, the edge of the lens 311 of the camera 310 is flush with the surface of the handle 200 to form a continuous concave surface.

Example III

The present embodiment provides an electric toothbrush for image acquisition and tooth cleaning, which is a further improvement based on the first embodiment, and the difference between the first embodiment and the second embodiment is that:

the light emitting assembly 600 in the present embodiment includes only the light emitting element 610 as a light source, without the lens 620. The handle 200 may be a non-transparent structure, but the non-transparent structure is thinned at a position corresponding to the light emitting element 610, so that the position corresponding to the light emitting element 610 has light transmittance, and the thinned portion of the light emitted by the light emitting element 610 provides illumination for the camera 310. Thus, not only the brightness of the camera 310 can be improved, but also the water can be effectively prevented from entering the cavity of the brush holder 200 because the brush holder 200 is of a closed structure.

In some possible embodiments, handle 200 is a light transmissive structure, such as handle 200 being a transparent or translucent structure. Thus, even if the handle 200 is not thinned at a position corresponding to the light emitting element 610, the light of the light emitting element 610 can be transmitted through the handle 200 to provide illumination. In this case, however, the elements within the cavity of handle 200 are visible.

Example IV

referring to fig. 7, in this embodiment, the brush head 100 includes a cover member 140 and bristles planted on an outer side surface of the cover member 140. The cover member 140 in some embodiments fully encloses the head of the handle 200. Wherein the head 100 and the head of the handle 200 are made of an elastically deformable plastic material, which may be a polypropylene material. The diameter of the blind bore within the cap member 140 is smaller than the diameter of the cross-section of the head of the handle 200. Thus, when the head of the brush handle 200 is inserted into the blind hole in the interior of the cap member 140, the brush head 100 and the head of the brush handle 200 can be fixedly coupled by the restoring force of the cap member 140. Therefore, the cover member 140 can shield the camera 310, and a user can prevent teeth from being scratched when touching the camera 310 during normal brushing with the electric toothbrush. On the other hand, the cover member 140 can also prevent external objects from scraping the camera 310 when the electric toothbrush is not in use, so as to protect the camera 310.
