An oral cleaning device 1 according to an embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1 to 9, an oral cleaning device 1 according to an embodiment of the present invention includes a housing 100, a light shielding layer 200, a light shielding member 300, and a light emitting member 400.

The housing 100 is a light-transmitting member, the housing 100 has a main body portion 110 and a display portion 120, an inner side of the display portion 120 is recessed to form a mounting groove 140, the display portion 120 is thinner than the main body portion 110, a light-shielding layer 200 is coated or adhered on an outer surface of the main body portion 110 to cover the main body portion 110, and a display area 230 is formed on the housing 100, a light-transmitting property of the light-shielding member 300 is smaller than the light-transmitting property of the housing 100, the light-shielding member 300 extends into the mounting groove 140 and is provided with a light-emitting channel 310, the light-emitting channel 310 is opposite to the display area 230, the light-emitting member 400 is arranged in the housing 100 and is located on a side of the light-emitting channel 310, which is opposite to the housing 100, and light of the light-emitting member 400 is emitted to the display portion 120 through the light-emitting channel 310 and is displayed in the display area 230.

The housing 100 may be made of light-transmitting plastic.

Wherein, the utility model discloses oral cavity cleaning device 1 can be for electric toothbrush or towards tooth ware etc. and light shield layer 200 can have a plurality of display areas 230, and every display area 230 corresponds the clean dynamics state of oral cavity cleaning device 1 or the electric quantity state of battery respectively.

According to the oral cleaning device 1 of the embodiment of the present invention, by setting the housing 100 as the light-transmitting member, and the housing 100 has the main body portion 110 and the display portion 120, the light shielding layer 200 is coated or pasted on the outer surface of the main body portion 110 to cover the main body portion 110, the light shielding layer 200 is formed with the display area 230 on the housing 100, and the positions of the display area 230 and the display portion 120 are right. It should be noted that, after the main body portion 110 is covered by the light shielding layer 200, the light passing through the main body portion 110 is shielded by the light shielding layer 200 and cannot be observed by a user, the light of the light emitting element 400 can pass through the display portion 120 to the outside of the casing 100, so that the light of the light emitting element 400 can be observed by the user, the display region 230 may be provided with no light shielding layer 200, so that the display portion 120 can transmit light, or the light shielding layer 200 has a relatively thin thickness at the display portion 120, so that the light of the light emitting element 400 can pass through the light shielding layer 200.

In addition, the inner side of the display part 120 is recessed to form the mounting groove 140, the display part 120 is thinner than the main body part 110, the light shielding member 300 extends into the mounting groove 140 and is provided with the light exit channel 310, so that the mounting groove 140 can reserve a mounting space for the light shielding member 300, and the groove wall of the mounting groove 140 can position the light shielding member 300, and fix the relative position between the light shielding member 300 and the housing 100, so that the light shielding member 300 is mounted in the mounting groove 140, so as to reduce the mounting space of the light shielding member 300 in the housing 100, thereby avoiding the light shielding member 300 from interfering with other components of the oral cavity cleaning device 1, and being beneficial to reducing the overall volume of the oral cavity cleaning device 1.

It can be understood that when light enters the display portion 120 of the housing 100, at least a portion of the light may propagate in other directions due to the scattering phenomenon of the colloid particles, and thus there may be a plurality of display regions 230, for example, the display region 230 displaying the first mode needs to be illuminated at present, but when light is emitted, the display region 230 corresponding to other modes may also be illuminated, that is, the display region 230 displaying the second mode is illuminated, and thus, the user may not accurately recognize the currently applied mode of the oral cleaning device 1. It is only described here by way of example, and of course, the rest of the cases are included, for example, when the display area 230 displaying the power is lightened, the display area 230 displaying the power mode may also be lightened, so that the user may be more confused about the current state of the oral cleaning device 1, and the use is inconvenient. It can be understood that, when the display portion 120 is thicker, the light rays propagating in other directions are more, and the crosstalk phenomenon is more obvious, that is, for example, when the display region 230 displaying the first mode is lighted, the display region 230 displaying the second mode, the display region 230 displaying the third mode, and the display region 230 displaying the fourth mode may be simultaneously lighted, and thus, the thicker the display portion 120 is, the lower the display accuracy is.

The thickness of the display part 120 according to the embodiment of the present invention is set to be thin, so that when the light of the light emitting member 400 irradiates the display part 120, the light scattered to other directions or regions is less, and thus the phenomenon of light fleeing is not likely to occur, for example, when the display region 230 displaying the first mode is illuminated, since the light transmitted to other directions is reduced, the luminance of the display region 230 displaying the first mode at first is higher, and the rest of the display regions 230 may not be irradiated with light, even if there is light irradiation, because the number of light is small, the luminance of the rest of the display regions 230 is far lower than the luminance of the display region 230 displaying the first mode, so that the user may not observe that the rest of the display regions 230 are illuminated, even if the rest of the display regions 230 are also illuminated, but because the difference between the luminances is large, the user can also accurately distinguish the currently applied mode of the oral cleaning device 1, thus, the light transmission isolation between the display regions 230 is better, and the display accuracy is effectively improved.

In addition, the light-shielding member 300 has a light transmittance smaller than that of the casing 100, the light-emitting channel 310 is opposite to the display area 230, the light-emitting member 400 is disposed in the casing 100 and located on a side of the light-emitting channel 310 opposite to the casing 100, and light of the light-emitting member 400 is emitted to the display portion 120 through the light-emitting channel 310 and is displayed in the display area 230.

The light-shielding member 300 may be made of an opaque material, so that when the light in the light-emitting channel 310 is refracted or scattered on the light-shielding member 300, the light is not easily emitted from the sidewall of the light-emitting channel 310, that is, the light mainly passes through the light-emitting channel 310 and is emitted from the display portion 120 of the housing 100; or the light shielding member 300 may be made of a light-transmitting material, in which case the surface of the light shielding member 300 may be coated with a light-transmitting coating, and since the light-transmitting property of the light shielding member 300 is smaller than that of the housing 100, the amount of light emitted from the side wall of the light-emitting channel 310 to other positions can be greatly reduced.

In the case where the light blocking member 300 is not provided, the light of the light emitting member 400 is transmitted further in the circumferential direction, not only in the direction of the corresponding display region 230, but also in the case where the display region 230 requiring the display of the first mode is lighted, the remaining display region 230 is lighted by the light emitting member 400.

Through the arrangement of the light-shielding member 300, in a first aspect, light of the light-emitting member 400 directly enters the light-emitting channel 310, so that the light of the light-emitting member 400 is prevented from scattering, the light of the light-emitting member 400 mainly irradiates the corresponding display region 230, and the light can be effectively prevented from being transmitted around the inside of the housing 100, for example, when the display region 230 which needs to display the first mode is lighted, the light of the light-emitting member 400 is transmitted only to the direction which displays the display region 230 of the first mode through the light-emitting channel 310, and at this time, the light of the light-emitting member 400 hardly irradiates the rest of the display regions 230, so that not only is the display accuracy improved, but also the brightness of the corresponding display region 230 can be improved, and the utilization rate of the light is improved;

in a second aspect, the light-emitting channel 310 may be almost perpendicular to the display portion 120, so that the light in the light-emitting channel 310 also irradiates the display portion 120 approximately perpendicularly, at this time, the light passes through the display portion 120 along a direction perpendicular to the display portion 120, and a transmission path of the light in the display portion 120 is shortened, so as to further reduce the amount of scattered light, thereby more effectively alleviating the problem of stray light, and reducing the amount of refraction and reflection of the light, and both the display accuracy and the brightness can be improved.

Moreover, the light shielding member 300 separates the light emitting member 400 from the housing 100, so as to prevent the housing 100 from colliding with the light emitting member 400, thereby protecting the light emitting member 400 and prolonging the service life of the light emitting member 400.

So, according to the utility model discloses oral cavity cleaning device 1 can avoid taking place to scurry the light phenomenon, has advantages such as printing opacity isolation is good and the outward appearance is clean and tidy.

In some embodiments of the utility model, light-proof 300 and casing 100 are the rigid, light-proof 300 pastes the inner wall of locating display portion 120, through setting up light-proof 300 to the rigid, be favorable to improving the structural strength of light-proof 300, avoid light-proof 300 to damage and warp, thereby guarantee the leaded light effect of light-proof 300 to the light of illuminating part 400, and easily light-proof 300 and casing 100 between fixed connection, light-proof 300 and casing 100 between difficult relative displacement that takes place, can avoid light-proof 300 towards the marginal light leak of display portion 120.

Alternatively, the light shield 300 is injection molded as one body with the housing 100.

For example, the light shielding member 300 is integrally formed, and then the light shielding member 300 is placed in the mold of the injection molding housing 100, so that the light shielding member 300 and the housing 100 are injection molded in the mold, thereby achieving the connection between the light shielding member 300 and the housing 100, not only increasing the connection strength between the light shielding member 300 and the housing 100, making the light shielding member 300 not easy to loosen and fall off from the housing 100, in the using process, the position of the light emitting channel 310 will not deviate relative to the display part 120, ensuring the alignment accuracy between the light emitting channel 310 and the display part 120, omitting the arrangement of the connection structure between the light shielding member 300 and the housing 100, reducing the installation steps of the light shielding member 300, simplifying the installation process, being beneficial to improving the production efficiency, and saving the processing cost.

In some embodiments of the present invention, the light-shielding member 300 is made of a light-tight material, or the light-shielding member 300 is provided with a light-tight coating layer surrounding the light-emitting channel 310, so that the light-shielding property of the light-shielding member 300 is high, the light of the light-emitting member 400 can not be transmitted from the side wall of the light-emitting channel 310, the interference between the adjacent light-emitting channels 310 is avoided, the isolation of the light is better, and the light-emitting utilization rate is improved.

In some embodiments of the present invention, as shown in fig. 3, the light shielding layer 200 is provided with the avoiding hole 210, the avoiding hole 210 surrounds the display portion 120 to form the display area 230, that is, the avoiding hole 210 of the light shielding layer 200 corresponds to the display portion 120 of the housing 100, the light shielding layer 200 covers the main body portion 110, the light of the light emitting member 400 transmitted to the main body portion 110 can be shielded by the light shielding layer 200, the light of the light emitting member 400 transmitted to the direction of the display portion 120 can be directly emitted to the outside of the housing 100 through the display portion 120 not only through the light shielding layer 200, so that the display area 230 can emit light, thereby displaying the working state of the oral cleaning device 1.

Alternatively, as shown in fig. 4, the light shielding layer 200 includes the thinning portion 220, the thickness of the thinning portion 220 is smaller than the thickness of the rest of the light shielding layer 200, the thinning portion 220 faces the display portion 120 to form the display region 230, when the thickness of the thinning portion 220 is small, the light of the light emitting member 400 can pass through the thinning portion 220, so that the display region 230 can emit light, and when the light emitting member 400 does not emit light, the thinning portion 220 can shield the display portion 120, so that the display portion 120 is in a hidden state, the boundary between the display portion 120 and the main body portion 110 is not easily observed by the user, and the appearance of the oral cavity cleaning device 1 is more beautiful.

In some embodiments of the present invention, as shown in fig. 5, the display area 230 includes a plurality of light-transmitting sub-areas, the light-emitting channel 310 is a plurality of light-transmitting sub-areas arranged at intervals, the light-emitting member 400 is a plurality of light-emitting members arranged at intervals, a plurality of light-emitting members 400, a plurality of light-emitting channels 310 and a plurality of light-transmitting sub-areas are in one-to-one correspondence, and the light of each light-emitting member 400 passes through the light-emitting channel 310 corresponding to the light-emitting member 400 to emit light to the light-transmitting sub-area corresponding to the light-emitting member 400.

Thus, the light of the plurality of light emitting members 400 can irradiate different light transmitting sub-regions through different light emitting channels 310, each light emitting channel 310 only transmits light to the direction of the light transmitting sub-region corresponding to the light emitting channel, the interference of the light among the plurality of light transmitting sub-regions is avoided, and the working state display of the oral cleaning device 1 is more reliable.

In some embodiments of the present invention, as shown in fig. 5 and 7, the outer sidewall of the light shielding member 300 is configured as a curved surface which is attached to the bottom wall of the mounting groove 140 in the circumferential direction of the housing 100, and the light emitting channel 310 may be configured at a position of the light shielding member 300 which is arched toward the housing 100.

Like this, the one side of the casing 100 that faces of light-shielding piece 300 and the inner wall laminating of casing 100 are inseparabler, and the one end of every light-emitting channel 310 towards casing 100 can end in the inner wall of casing 100, does not have clearance or clearance minimum between the inner wall of light-emitting channel 310 and casing 100, and the light permeability of preventing between light-emitting channel 310 and the casing 100 is better, is difficult for taking place the light leak between light-emitting channel 310 and the casing 100.
