The housing 100 includes an opaque substrate 110 and a transparent member 120, the opaque substrate 110 has a transparent through hole 111, the transparent member 120 is filled in the transparent through hole 111 to form a transparent portion 130, and the light emitting member 200 is disposed in the housing 100 and emits light toward the transparent portion 130. The housing 100 further includes a light-transmitting opaque cover layer 140, the cover layer 140 is disposed on the outer surface of the opaque substrate 110 and shields the light-transmitting portion 130, light emitted by the light-emitting member 200 can sequentially pass through the light-transmitting portion 130 and the cover layer 140 to be transmitted, and when the light-emitting member 200 does not emit light, the cover layer 140 covers the light-transmitting portion 130 to make it invisible.

Wherein, personal care equipment 3 can be for oral cavity cleaning equipment such as electric toothbrush or tooth flushing device, the utility model discloses personal care equipment hand utensil 1 can be for the handle of oral cavity cleaning equipment such as electric toothbrush or tooth flushing device for grip.

According to the utility model discloses personal equipment nursing equipment hand utensil, through being divided into opaque base member 110 and printing opacity piece 120 with casing 100, opaque base member 110 is equipped with printing opacity through-hole 111, printing opacity through-hole 111 runs through the lateral wall of opaque base member 110, it is luminous to the direction of printing opacity portion 130 that casing 100 is located to light-emitting piece 200, light-emitting piece 200's light can pass opaque base member 110 through printing opacity through-hole 111 and transmit, printing opacity piece 120 is filled in printing opacity through-hole 111 in order to form printing opacity portion 130.

Wherein, light-tight base member 110 can be the opaque working of plastics, be used for blockking the transmission of light, light neither can see through light-tight base member 110 and transmit, also can transmit in light-tight base member 110's inside, light-transmitting member 120 can be the non-light tight working of plastics, light-transmitting member 120 allows the transmission of light, light-transmitting member 120 can not block light-emitting member 200 promptly and transmit along printing opacity through-hole 111, and light-transmitting member 120 can block impurity such as dust impurity and liquid and pass in printing opacity through-hole 111 enters into casing 100, in order to improve the leakproofness of personal care equipment hand piece 1.

Moreover, because the opaque substrate 110 has the property of non-light transmission, the plurality of light transmission through holes 111 are arranged on the opaque substrate 110, when light exists in one light transmission through hole 111, the light emission phenomenon does not occur in the rest light transmission through holes 111, that is, the problem of light conduction does not exist between any two light transmission through holes 111, the phenomenon of linkage light emission does not exist between any two light transmission through holes 111, the light transmission isolation is good, and the display independence is better.

In addition, the casing 100 further includes a light-transmitting opaque covering layer 140, the covering layer 140 is disposed on an outer surface of the opaque substrate 110 and covers the light-transmitting portion 130, and the light-transmitting opaque of the covering layer 140 means that light of the light-emitting member 200 can pass through the covering layer 140 to be emitted to the outside of the casing 100, light of the light-emitting member 200 can be observed by a user, and structures inside the casing 100 cannot be observed from the outer surface of the casing 100.

Thus, masking layer 140 can block the area of translucent portion 130 and opaque substrate 110 adjacent to translucent portion 130, when light emitting component 200 emits light, the light from light emitting component 200 can be transmitted outward through translucent portion 130 and masking layer 140, the user can still observe the brightness of translucent portion 130, when light emitting component 200 does not emit light, masking layer 140 can mask translucent portion 130, so that translucent portion 130 is hidden, the user can not observe the boundary between translucent portion 130 and opaque substrate 110, and the overall appearance of personal care device hand piece 1 is cleaner and tidier. Moreover, the covering layer 140 is arranged to cover the light-transmitting portions 130, so that light-transmitting interference between adjacent light-transmitting portions 130 is further weakened, a light-transmitting isolation effect is optimized, and display independence is stronger.

Therefore, the personal care equipment hand tool 1 according to the embodiment of the present invention can avoid the light transmission interference between the adjacent light transmission parts 130, and has excellent display independence.

In some embodiments of the present invention, as shown in fig. 5, the outer surface of light transmissive element 120 is flush with the outer surface of opaque substrate 110. Where flush means that the difference between the outer surface of light transmissive element 120 and the outer surface of opaque substrate 110 is in the range of-1 mm to 1mm, such as-1 mm, 0.5mm, 0mm, 0.5mm, or 1mm, i.e., the outer surface of light transmissive element 120 can be at most 1mm higher than the outer surface of opaque substrate 110, or the outer surface of light transmissive element 120 can be at most 1mm lower than the outer surface of opaque substrate 110.

It should be noted that, the thickness of the covering layer 140 may be thinner, the covering layer 140 may be coated on the outer surface of the opaque substrate 110 and the outer surface of the light transmissive member 120, and the outer surface of the light transmissive member 120 is flush with the outer surface of the opaque substrate 110, so that the surface of the covering layer 140 coated on the outer surface of the opaque substrate 110 and the outer surface of the light transmissive member 120 is smoother, and has a better hiding effect on the light transmissive portion 130 when the light emitting member 200 does not emit light, and the outer surface of the covering layer 140 does not form a recessed structure, thereby avoiding accumulation of dust and impurities, and being beneficial to keeping the outer surface of the personal care device hand set 1 clean.

For example, keeping the outer surface of light-transmitting member 120 flush with the outer surface of opaque substrate 110, the flatness relationship between light-transmitting member 120 and opaque substrate 110 after filling light-transmitting through hole 111 can be controlled by a mold, that is, the thickness of light-transmitting member 120 is controlled to be close to the thickness of opaque substrate 110, so that the outer surface of light-transmitting member 120 and the outer surface of opaque substrate 110 can be kept flat after light-transmitting member 120 is assembled in light-transmitting through hole 111; alternatively, the outer surface of light-transmitting member 120 may be disposed to protrude from the outer surface of opaque substrate 110, and after light-transmitting member 120 is filled in light-transmitting through hole 111, the portion of light-transmitting member 120 higher than the outer surface of opaque substrate 110 is polished until the outer surfaces of light-transmitting member 120 and opaque substrate 110 are flat.

In addition, the masking layer 140 may coat the opaque substrate 110 along the circumferential direction of the housing 100, wherein the circumferential direction of the housing 100 is the direction surrounding the length of the housing 100, the masking layer 140 has a larger coating area, the covering effect is better, and unevenness between the outer surface of the housing 100 and the masking layer 140 in the circumferential direction of the housing 100 can be prevented;

alternatively, the covering layer 140 may only coat the side of the casing 100 where the light-transmitting portion 130 is disposed, so that the covering layer 140 not only can cover the light-transmitting portion 130 to make the light-transmitting portion 130 invisible when the light-emitting member 200 does not emit light, but also the covering layer 140 has a smaller coating area, higher processing efficiency and lower cost.

In some embodiments of the present invention, the opaque substrate 110 is cylindrical, and the covering layer 140 annularly covers the outer surface of the opaque substrate 110 at least at the transparent portion 130.

For example, masking layer 140 may be coated on the outer surface of opaque substrate 110 by spraying, and by disposing opaque substrate 110 in a cylindrical shape, opaque substrate 110 is rotated along the central axis of opaque substrate 110, so that masking layer 140 is uniformly coated on the outer surface of opaque substrate 110, and the phenomenon that masking layer 140 is locally thick and locally thin does not occur on the outer surface of opaque substrate 110, so that the thickness of masking layer 140 is more uniform.

In addition, after the personal care apparatus hand piece 1 is assembled, the user usually holds the portion of the opaque substrate 110 when using the personal care apparatus hand piece, and the cylindrical opaque substrate 110 is more suitable for the holding habit of the user, so that the user can hold the personal care apparatus hand piece more comfortably.

In some embodiments of the present invention, as shown in fig. 5, the light-transmitting through holes 111 are plural, the plural light-transmitting through holes 111 are arranged along at least one of the length direction and the circumferential direction of the opaque substrate 110, and the light-transmitting member 120 is filled in the plural light-transmitting through holes 111 to form the plural light-transmitting portions 130.

When the light-proof base 110 is provided with the plurality of light-transmitting through holes 111, the light-proof base 110 can have a good blocking effect on light, and light interference cannot occur between the adjacent light-transmitting through holes 111, so that the light-emitting blocking effect between the plurality of light-transmitting parts 130 of the personal care equipment hand 1 is better, when one of the plurality of light-transmitting parts 130 emits light, the adjacent light-transmitting part 130 cannot be influenced, and the user experience is better.

For example, the plurality of light-transmitting portions 130 may be disposed at intervals along the length direction of the opaque substrate 110; alternatively, the plurality of light-transmitting portions 130 may be disposed at intervals in the circumferential direction of the opaque base 110; or, some of the plurality of light-transmitting portions 130 are disposed at intervals along the length direction of the opaque base 110, and another of the plurality of light-transmitting portions 130 is disposed at intervals along the circumferential direction of the opaque base 110, so that the plurality of light-transmitting portions 130 are disposed in a variety of manners.

Because the plurality of light-transmitting parts 130 are arranged, and the plurality of light-transmitting parts 130 respectively correspond to one of the different modes of the personal care equipment hand 1, when one of the light-transmitting parts 130 emits light, it indicates that the personal care equipment hand 1 is in the mode corresponding to the light-transmitting part 130 at the moment, and a user can judge the mode of the personal care equipment hand 1 by observing the light-emitting conditions of the different light-transmitting parts 130, so that the use feedback effect is good.

In some embodiments of the present invention, as shown in fig. 4 and 6, the personal care device hand piece 1 further comprises a light guide 300.

The light guide 300 is disposed in the opaque substrate 110 and has a light guide channel 310, and light emitted from the light emitting member 200 is emitted to the light-transmitting portion 130 through the light guide channel 310.

The light guide channels 310 of the light guide member 300 may be multiple, the light transmission portions 130 and the light emitting members 200 may also be multiple, the light emitting members 200, the light guide channels 310 and the light transmission portions 130 correspond to each other one by one, and light rays between the light guide channels 310 do not interfere with each other, so that each light guide channel 310 may guide light of the light emitting member 200 corresponding to the light guide channel to the light transmission portion 130 corresponding to the light guide channel, and prevent the light of the light emitting member 200 from being incident on other light transmission portions 130 in the process of being transmitted to the light transmission portion 130, thereby preventing light emission interference between the light transmission portions 130, and the light guide channels 310 may also prevent the light of the light emitting members 200 from leaking outwards, so that light leakage prevention performance is good, and light emission utilization rate is high.

Further, as shown in fig. 2-4, the personal care appliance hand piece 1 further comprises a circuit board 400.

The circuit board 400 is arranged in the opaque substrate 110, the light-emitting member 200 is arranged on one side of the circuit board 400 facing the light-guiding member 300, so that the light of the light-emitting member 200 is not blocked by the circuit board 400 when the light is transmitted to the light-guiding member 300, and the circuit board 400 can control the light-emitting member 200 to emit light and stop emitting light, thereby enabling the light of the light-emitting member 200 to irradiate towards the light-transmitting portion 130 as far as possible, so as to ensure that the brightness of the light-transmitting portion 130 is sufficient, furthermore, the circuit board 400 can also shield the light of one side of the light-emitting member 200 facing away from the light-guiding member 300, further improving the light-emitting sealing performance of the personal care equipment hand tool 1, and achieving better light leakage prevention effect.

The light guide 300 is an elastic member and is clamped between the circuit board 400 and the inner surface of the opaque substrate 110, for example, the light guide 300 may be made of foam, such as PU (polyurethane) foam, and the light guide 300 may be glued to the circuit board 400. The light guide 300 is light and elastic, and can guide the light of the light emitting element 200, and when the user presses the personal care device hand piece 1, the light guide 300 can elastically deform, so that the extrusion force of the light guide 300 to the electronic components on the circuit board 400 is reduced, and the circuit board 400 is prevented from being damaged.

Or, the light guide 300 is rigid and is connected with the circuit board 400, for example, the light guide 300 may be rigid plastic, by setting the light guide 300 to be rigid, it is beneficial to improve the structural strength of the light guide 300, avoid the light guide 300 from being damaged, thereby ensuring the light guiding effect of the light guide 300, and the circuit board 400 may fix the light guide 300 and the light emitting member 200 at the same time, avoid the light guide 300 from deviating from the light emitting member 200, and the light guide 300 has a better guiding effect on the light of the light emitting member 200.

Further, when the light guide 300 is a rigid member, the side of the light guide 300 facing the circuit board 400 is provided with an avoiding groove to avoid electronic components of the circuit board 400 facing the light guide 300, and the groove is arranged to avoid the rigid light guide 300 and the components of the circuit board 400, so as to avoid the interference between the light guide 300 and the components, thereby protecting the electronic components of the circuit board 400 from being damaged, and simultaneously enabling the light guide 300 and the circuit board 400 to be tightly attached as much as possible, and avoiding the edge light leakage of the light guide 300.

Optionally, as shown in fig. 3, the light emitting element 200 extends into the light guiding channel 310, so that the light emitted by the light emitting element 200 can be completely irradiated into the light guiding channel 310, and the light guiding channel 310 has a better light gathering effect on the light emitting element 200, so that the light emitted by the light emitting element 200 can be irradiated onto the light transmitting portion 130 along the light guiding channel 310, thereby improving the light emitting brightness of the light transmitting portion 130, avoiding the loss of the light emitted by the light emitting element 200 in the process of transmitting the light into the light guiding channel 310, and improving the utilization efficiency of the light emission.

In addition, one end of the light guide channel 310 abuts against the inner surface of the casing 100 and is covered by the inner surface of the casing 100, and the other end of the light guide channel 310 abuts against the circuit board 400 and is covered by the circuit board 400, so that no light leakage occurs between the light guide channel 310 and the inner wall of the casing 100, and no light leakage occurs between the light guide channel 310 and the circuit board 400, that is, both ends of the light guide channel 310 are covered, the light leakage prevention performance of the personal care equipment hand 1 is better, the light emitting interference between adjacent light transmitting portions 130 is further avoided, and the light of the light emitting member 200 is mainly used for illuminating the light transmitting portions 130, which is beneficial to further improving the light emitting brightness of the light transmitting portions 130, and further improving the utilization efficiency of light emission.

In some embodiments of the present invention, as shown in fig. 2 and 4, the personal care device hand piece 1 further comprises a vibrating member 500. The vibrating member 500 may be a driving member of the hand tool 1 of the personal care apparatus, such as a motor, which generates vibration during operation.

Opaque substrate 110 includes a handle portion 112 adapted to be held by a human hand, and vibrating element 500 and light emitting element 200 are mounted within handle portion 112 with a distance between light emitting element 200 and an inner surface of handle portion 112 of 0.3mm to 3mm, such as 0.3mm, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, or 3 mm. Wherein, the light emitting member 200 does not extend beyond a side of the light guide channel 310 facing away from the light emitting member 200, so that the light guide 300 can block the light emitting member 200 from colliding with the housing 100.

Therefore, on one hand, by limiting the distance between the light emitting element 200 and the inner surface of the handle part 112 to be not less than 0.3mm, the distance between the light emitting element 200 and the inner surface of the housing 100 can be prevented from being too small, so that when the technical vibration element 500 vibrates, the collision between the light emitting element 200 and the handle part 112 can be avoided, and the light emitting element 200 can be prevented from being damaged; on the other hand, limiting the distance between luminous member 200 and the inner surface of handle portion 112 to be not more than 3mm can avoid the problem that the distance between luminous member 200 and the inner surface of handle portion 112 is too large, which causes the light transmission performance of light transmission portion 130 to be poor, ensure the brightness of light transmission portion 130, and is advantageous for reducing the volume of personal care apparatus hand piece 1.

In some embodiments of the present invention, the hardness of the transparent member 120 and the hardness of the opaque substrate 110 are both sufficient to produce a deformation invisible to the naked eye when subjected to a non-destructive force.

Wherein, light-tight base member 110 can be light-tight plastics, and printing opacity piece 120 can be light-transmitting plastics, heats printing opacity piece 120 earlier, makes the shape of printing opacity piece 120 can change, fills printing opacity piece 120 into printing opacity through-hole 111 again, and makes the shape of printing opacity piece 120 and the shape adaptation of printing opacity through-hole 111, and at last for printing opacity piece 120 cooling, make printing opacity piece 120 solidify, guarantee that the structural strength of printing opacity piece 120 is enough high.

Thus, the hardness of light-transmitting member 120 and the hardness of opaque substrate 110 are both high, and the hardness of light-transmitting member 120 after curing is substantially equal to the hardness of opaque substrate 110, so that the outer surface of light-transmitting member 120 after being polished and the outer surface of opaque substrate 110 do not have obvious boundary feeling, the hiding effect of light-transmitting portion 130 is further increased, and light-transmitting portion 130 is less likely to be observed when not emitting light.

Moreover, when the masking layer 140 covers the outer surface of the light-transmitting member 120 and the outer surface of the opaque substrate 110, since the hardness of the cured light-transmitting member 120 is substantially equal to that of the opaque substrate 110, the interface between the light-transmitting member 120 and the opaque substrate 110 is not deformed or deformed uniformly, and the masking layer 140 does not crack or split at the interface between the light-transmitting member 120 and the opaque substrate 110 due to the difference in hardness between the light-transmitting member 120 and the opaque substrate 110.
