Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

In the related art, the structural design schemes of the light guide assembly in the electric toothbrush are mainly divided into two categories:

the first type is that the luminous element is directly arranged on a circuit board of the electric toothbrush, the irradiation light of the luminous element is guided to all positions of the annular light guide component by the annular light guide component, and then the irradiation light is uniformly transmitted to a light transmission area of a handle barrel of the electric toothbrush by the annular light guide component; it can be understood that, in the present design, the position for placing the light emitting element needs to be reserved on the circuit board, and the distance (i.e., the light guiding distance) between the circuit board and the light transmitting area of the handle barrel cannot be too long. Moreover, in order to improve the light guiding efficiency of the irradiated light, light scattering powder cannot be added in the light guiding assembly, so that the light displayed in the light transmitting area of the handle cylinder is dazzling and not soft.

The second type is that a light emitting assembly (such as an LED lamp panel) is disposed in the electric toothbrush, and a plurality of light emitting elements on the light emitting assembly irradiate toward the annular light guide assembly, and the plurality of light emitting points guide all positions of the annular light guide assembly, and then the annular light guide assembly transmits irradiation light to a light transmission area of a handle cylinder of the electric toothbrush. It can be appreciated that the present design requires a separate light emitting assembly within the electric toothbrush, and the light emitting assembly needs to be spaced from the light transmissive region of the handle barrel; however, since the space in the electric toothbrush is limited, the light intensity of the irradiation light corresponding to the region other than the light beam angle of the single light emitting element is weak, and thus the region other than the light beam angle of each light emitting element is dark, thereby causing the condition that the light intensity is not uniform in the light transmitting region of the handle barrel.

The disclosed embodiments provide a hand held component, as shown in fig. 1-4, fig. 1 is a schematic view of a structural elevation of a hand held component shown according to an exemplary embodiment; FIG. 2 is a schematic illustration of a hand held component shown in a top view in a configuration according to an exemplary embodiment; FIG. 3 is a schematic diagram illustrating an elevation of an internal structure of a hand held unit in accordance with an exemplary embodiment;

fig. 4 is a schematic top view of the internal structure of a hand held unit according to an exemplary embodiment. The hand-held component 10 includes:

a housing 11, a light-transmitting region 11a formed on the housing 11, the light-transmitting region 11a extending along a circumferential direction of the housing 11;

a light guide assembly 12, the light guide assembly 12 being disposed in the housing 11, the light guide assembly 12 having a light incident surface for guiding light received by the light incident surface to the light transmitting region 11a of the housing 11;

a light emitting element 13 disposed in the housing 11;

wherein, light emitting component 13 includes:

at least two light emitting elements 131, the overlapping illumination range of at least two light emitting elements 131 covers the light incident surface of the light guide assembly 12, and the power angles a of two adjacent light emitting elements 131 are at least partially overlapped.

In some embodiments of the present disclosure, the handheld component 10 includes: a housing 11, a light guide assembly 12 and a light emitting assembly 13. An accommodating cavity is formed inside the housing 11, and the light guide assembly 12 and the light emitting assembly 13 are both disposed in the accommodating cavity of the housing 11.

The light guide member 12 is disposed adjacent to the light emitting member 13 and guides the illumination light of the light emitting member 13 to the light transmitting region 11a of the housing 11.

It can be understood that the light guide assembly 12 may have a light incident surface and a light emitting surface; the light incident surface faces the light emitting element 13, and the light emitting surface faces the light transmitting region 11a of the housing 11.

Here, the outer wall of the housing 11 forms a light transmitting region 11a extending in a circumferential direction thereof, and it is understood that the outer wall of the housing 11 is formed with an annular light transmitting region 11a.

The shape of the light-transmitting area 11a is matched with the shape of the light-emitting surface of the light guide assembly 12; in the embodiment of the present disclosure, the light-transmitting region 11a may be a closed annular region; it will be appreciated that the closed annular light transmitting region 11a allows a user to view the light emission of the light emitting assembly at a plurality of different angles around the circumference of the housing.

In other embodiments, the light-transmitting region 11a may also be an open annular region.

It should be noted that, since the light-transmitting region 11a is formed on the outer wall of the housing 11, when the light-emitting element 13 in the housing 11 irradiates towards the light-incident surface of the light-guiding element 12, the light-guiding element 12 uniformly emits the light received by the light-incident surface by using the light-emitting surface to transmit the light to the light-transmitting region 11a of the housing 11, so that a user can directly observe the light-emitting condition of the light-emitting element 13 in the light-transmitting region 11a of the housing 11.

Moreover, in the embodiment of the present disclosure, since the light-transmitting area 11a extends along the circumferential direction of the outer wall of the housing 11, even if the relative position between the front surface of the housing 11 (i.e., the surface of the housing on which the operation buttons are arranged) and the user changes, the user can observe the light-emitting condition of the light-emitting component 13 through the light-transmitting area 11a arranged on the circumferential direction of the housing 11; that is, based on the light-transmitting region 11a circumferentially disposed on the housing 11, the user can observe the light-emitting condition of the light-emitting assembly 13 from a plurality of different angles.

In the embodiment of the present disclosure, the light guide element 12 may be an annular structure, and an inner wall surface of the light guide element 12 facing the light emitting element 13 is a light incident surface of the light guide element 12; utilize the light guide component 12 of annular structure for the light that shines that light emitting component 13 sent forms the effect of annular light after light guide component 12 refracts or diffuse reflection, thereby conducts to the annular light-transmitting zone 11a of casing 11 and shows, so that the user can observe light emitting component 13's luminous condition from a plurality of different angles.

The light assembly 13 is operable in different light emitting modes according to different states of the handheld device 10, so that a user can observe the different light emitting modes of the light assembly 13 through the light-transmitting region 11a of the housing 11 to determine the current state of the handheld device 10.

Here, the light emitting pattern of the light emitting assembly 13 may include: color pattern, blinking frequency pattern, etc. The embodiments of the present disclosure are not limited thereto.

For example, the light emitting element 13 can operate in different color modes according to different power states of the handheld component 10. When the handheld component 10 is sufficiently charged, the light-emitting assembly 13 is in a green light mode, and the user can determine that the handheld component 10 is sufficiently charged by observing green light through the light-transmitting area 11a of the housing 11; when the handheld device 10 is low in power, the light emitting assembly 13 is in the red light mode, and the user can observe the red light through the light-transmitting area 11a of the housing 11, so that it can be determined that the handheld device 10 is currently low in power and the handheld device 10 needs to be charged.

The light emitting assembly 13 may include: at least two light emitting elements 131. The at least two light emitting elements 131 irradiate towards the light incident surface of the light guide assembly 12, and the overlapped irradiation range of the at least two light emitting elements 131 covers the light incident surface of the light guide assembly 12.

Here, the light emitting element 131 may be an LED light source.

It should be noted that, because the light emitting element 131 is a point light source, the irradiation range of the light emitting element 131 is limited, if only a partial region of the light incident surface of the light guide assembly 12 receives light, only a partial region of the annular light transmitting region 11a of the housing 11 can receive light transmitted from the light guide assembly 12, so that light is emitted only through a partial region of the annular light transmitting region 11a of the housing 11, that is, the annular light transmitting region 11a of the housing 11 has a condition of uneven light distribution, so that a user can only observe the light emitting condition of the light emitting assembly 13 at the position region of the annular light transmitting region 11a of the housing 11, which affects the user experience.

This disclosed embodiment is through setting up two at least light emitting component 131 in light emitting component 13, and through the range position of adjusting two at least light emitting component 131 in light emitting component 13, make the range of illumination of the stack of two at least light emitting component 13 cover the income plain noodles of leaded light subassembly 12, thereby make the different positions of the annular light transmission region 11a of casing 11 all can receive the light that is transmitted by leaded light subassembly 12, make light can launch through arbitrary region in the annular light transmission region 11a of casing 11, so that the user can all observe the luminous condition of light emitting component 13 from a plurality of different angles, promote user's use experience.

In addition, in the disclosed embodiment, the power angles a of adjacent two of the at least two light emitting elements 131 at least partially overlap.

Here, the power angle a of the light emitting element 131 is a scattering angle of the irradiation light of the light emitting element 131.

It is understood that the smaller the scattering angle of the irradiation light of the light emitting element 131 is, the greater the light intensity of the irradiation light within the scattering angle is; conversely, the larger the scattering angle of the irradiation light of the light emitting element 131, the smaller the light intensity of the irradiation light within the scattering angle.

In the irradiation range of the light emitting element 131, the scattering angle of the irradiation light may be different for different positions, and the light intensity may also be different. For example, the scattering angle of the irradiation light corresponding to the central region within the irradiation range of the light emitting element 131 is small, and the light intensity of the irradiation light at the position is large; the light-emitting element 131 has a large scattering angle of the irradiation light corresponding to the edge region of the irradiation range, and the light intensity of the irradiation light at that position is small.

It can be understood that the scattering angle of the illuminating light corresponding to the overlapping region of the power angles a of the two light emitting elements 131 is larger than the scattering angle of the illuminating light corresponding to the non-overlapping region of the power angles a of the two light emitting elements 131, so that the light intensity of the illuminating light of the light emitting element 131 corresponding to the overlapping region is smaller than the light intensity of the illuminating light of the light emitting element 131 corresponding to the non-overlapping region.

Because the power angles a of two adjacent light-emitting elements 131 in the at least two light-emitting elements 131 are at least partially overlapped, the light incident region corresponding to the overlapping region of the power angles a in the light incident surface of the light guide assembly 12 can receive the irradiation light of the two light-emitting elements 131, so as to improve the light intensity of the irradiation light received by the light incident region, reduce the condition of non-uniform light intensity in different regions in the light incident surface of the light guide assembly 12, and reduce the condition of non-uniform light intensity distribution in the annular light-transmitting region 11a of the housing 11.

In the embodiment of the present disclosure, at least two light emitting elements 131 are disposed in the light emitting assembly 13, and the arrangement positions of the at least two light emitting elements 131 in the light emitting assembly 13 are adjusted, so that the overlapping illumination ranges of the at least two light emitting elements 131 cover the light incident surface of the light guide assembly 12; moreover, the power angles a of two adjacent light-emitting elements 131 in at least two light-emitting elements 131 are at least partially overlapped, so that the irradiation light of the light-emitting elements 131 can be received at different positions of the light incident surface of the light guide assembly 12, and the intensity of the received irradiation light is relatively uniform, so that the light guide assembly 12 can uniformly transmit the irradiation light to the light-transmitting region 11a of the housing 11. The light-transmitting region 11a is reduced in the case where the light intensity distribution is not uniform.

In addition, the light-transmitting area 11a extending in the circumferential direction is arranged on the shell 11 of the handheld component 10, so that a user can observe the light-emitting condition of the light-emitting assembly 13 in the handheld component 10 from a plurality of different angles, and the use experience of the user is improved.

Alternatively, as shown in FIGS. 1-2 and 5-6, FIG. 5 is a schematic perspective view of a hand held unit according to an exemplary embodiment; fig. 6 is a schematic top view of a hand held component according to an exemplary embodiment. A housing 11, comprising:

a cylinder 111, wherein a first opening is arranged at one end of the cylinder 111 along the length direction;

the cylinder cover 112, the cylinder cover 112 locates on cylinder 111, and close the first opening of the cylinder 111; the cylinder 111 and the cylinder cover 112 together form a light shielding area 11b of the housing 11;

the light-transmitting component 113, the light-transmitting component 113 is located between the cylinder 111 and the cylinder cover 112, and forms a light-transmitting area 11a of the housing 11.

In the disclosed embodiment, the housing 11 may include: barrel 111, barrel lid 112 and light transmission component 113.

The barrel 111 may be a hollow structure, and an accommodating cavity is formed inside the barrel 111 so as to place the light guide assembly 12 and the light emitting assembly 13 in the barrel 111. It will be appreciated that power components, mounting brackets, circuit boards, etc. may also be disposed within the barrel 111.

Here, the cylindrical body 111 may be a cylindrical body 111, or may be a cylindrical body 111 having a rectangular or oval cross section. The barrel 111 may be made of a light-shielding material, and it can be understood that since elements such as a power supply assembly, a fixing bracket, and a circuit board are disposed inside the barrel 111, the barrel 111 made of the light-shielding material shields the internal structure of the barrel 111, thereby improving the aesthetic appearance of the hand-held component 10.

The cylinder 111 may include a first opening disposed at one end of the cylinder 111 in the length direction.

The barrel 111 has opposite first and

second ends

1111 and 1112 in a length direction, and the first opening may be provided at the first end 1111 of the barrel 111.

It should be noted that the first end 1111 of the cylinder 111 along the length direction may be the top end of the cylinder 111, and the second end 1112 of the cylinder 111 along the length direction may be the bottom end of the cylinder 111; it will be appreciated that the top end of the barrel 111 is the end that is connected to the external working member.

The cap 112 is disposed on the cylinder 111 to close the first opening of the cylinder 111.

It should be noted that the cover 112 may be made of a light-shielding material. It can be understood that the barrel 111 and the barrel cover 112 together form the light shielding region 11b of the housing 11 in the embodiment of the present disclosure.

Because the cylinder cover 112 is used for closing the first opening of the cylinder 111, the cylinder cover 112 made of the shading material prevents a user from directly observing the internal structure of the cylinder 111 from the cylinder cover 112, thereby shielding the internal structure of the cylinder 111 and improving the aesthetic degree of the handheld component 10.

The light transmission component 113 is located between the cylinder 111 and the cylinder cover 112, so that the illumination light emitted by the light emitting component 13 in the cylinder 111 is conducted to the light transmission component 113 through the light guide component 12, and the illumination light is output by the light transmission component 113.

Here, the light-transmitting member 113 may be a transparent material or a translucent material.

In some embodiments, in order to make the light transmission component 113 uniformly and softly guide out the received irradiation light, the light transmission component 113 may be injection molded by a light-homogenizing material formed by mixing a transparent material and light scattering powder.

It is understood that the light transmissive member 113 may be an annular structure; utilize annular structure's printing opacity subassembly 113 to constitute the printing opacity regional 11a of circumference extension on the casing 11, can effectively increase the printing opacity regional 11a on casing 11 surface on the one hand for visual effect is more obvious, and on the other hand utilizes annular structure's printing opacity subassembly 113 for the user can follow a plurality of different angles and observe the luminous condition of the light emitting component 13 in the handheld part 10, promotes user's use and experiences.

In the embodiment of the present disclosure, the barrel 111, the light-transmitting component 113, and the barrel cover 112 may be separate components, and the barrel 111, the light-transmitting component 113, and the barrel cover 112 are assembled to form the housing 11 of the handheld component 10 by bonding, clamping, and the like.

Optionally, the housing 11 is: the barrel 111, the light transmission member 113, and the barrel cover 112 are formed as an integrated structure based on a multi-injection molding process.

In the embodiment of the present disclosure, the barrel 111, the light transmission member 113 and the barrel cover 112 may be sequentially formed into the housing 11 of an integrated structure through a multi-injection molding process.

It can be understood that, by means of multiple injection molding, on one hand, the light-transmitting area 11a and the light-shielding area 11b of the housing 11 are effectively isolated; on the other hand, the housing 11 can be provided with waterproof performance.

Alternatively, as shown in FIG. 7, FIG. 7 is a cross-sectional schematic view of a hand held component shown in accordance with an exemplary embodiment. The projection of the light emitting element 131 toward the housing 11 is located on the cylindrical body 111 of the housing 11.

In the disclosed embodiment, the projection of the light emitting element 131 toward the housing 11 may be located on the cylinder 111 of the housing 11. It can be understood that since the tube 111 and the tube cover 112 together form the light shielding region 11b of the housing 11, the tube 111 can shield the irradiation light emitted from the light emitting element 131.

If the projection of the light emitting element 131 toward the housing 11 is located in the light transmitting area 11a of the housing 11, the illumination light emitted by the light emitting element 131 may directly irradiate the light transmitting area 11a of the housing 11, which may cause the light transmitting area 11a of the housing 11 to be dazzling and not soft, and reduce the user experience.

The present disclosure adjusts the position of the light emitting element 131 in the housing 11, so that the projection of the light emitting element 131 toward the housing 11 is located in the cylinder 111 (i.e., the light shielding region 11 b) of the housing 11. Since the light-shielding region 11b of the housing 11 is opaque, even if the light emitted from the light-emitting device 131 directly irradiates the light-shielding region 11b of the housing 11, the light-shielding region 11b can shield the irradiated light; the light emitted from the light-transmitting area 11a of the housing 11 is the light which is irradiated by the light guide assembly 12 in the housing 11 to the light-emitting element 131 through secondary refraction and diffuse reflection, and the light is softer, so that the use experience of the user is improved.

Alternatively, as shown in fig. 7-8, fig. 8 is a partially enlarged schematic view according to fig. 7.
