[0083] With reference to the drawings and the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work are within the protection scope of the present application. In addition, the technical solutions in the various embodiments can be combined with each other, but the combination of the technical solutions should be based on the fact that a person of ordinary skill in the art can realize the combination, and when the combination of the technical solutions appears contradictory or unachievable, it should be considered that the combination of the technical solutions does not exist, and is not within the protection scope of the present application.

[0084] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0085] In addition, if the embodiments of the present application involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for description purposes, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing throughout the text is that it includes three parallel solutions. For example, "A and / or B" includes A solution, or B solution, or A and B solutions.

[0086] The present application provides five independent schemes, and the following points need to be explained in advance: first, regarding the component names, the component names of each scheme in the five schemes of the present application are independent of each other and are not mutually referenced. For example, the component names in the first scheme are only applicable to the first scheme and are not applicable to the second scheme to the fifth scheme. Even if the second scheme to the fifth scheme has the same name as the first scheme, the components referred to are different, which has no relation with the first scheme. Or, the second scheme to the fifth scheme has the same component as the first scheme, but the name is different, which also has no relation with the first scheme. As for the second scheme to the fifth scheme being the same as the first scheme, the same understanding can be made, and details are not repeated. Next, examples will be given to illustrate:

[0087] (1) The transparent panel in the first scheme and the transparent cover plate in the fourth scheme represent the same component, but the names are different in different schemes. Please understand the respective names in each scheme.(2) The light guide hole in the first scheme and the light guide through hole in the fourth scheme represent the same component, but the names are different in different schemes. Please understand the respective names in each scheme.(3) The light transmission micro hole in the first scheme and the light transmission hole in the fourth scheme represent the same component, but the names are different in different schemes. Please understand the respective names in each scheme. There are still some of the above-mentioned components that represent the same component, but the component names are different in the five schemes. Please refer to the above method for the same understanding and processing, and this embodiment will not be illustrated one by one.

[0088] (4) The same name lugs exist in the first and third schemes, but the lugs in the first scheme and the lugs in the third scheme refer to different components, that is, the same name but different components. Please understand the respective names in each scheme.(5) The same name mounting plate exists in the first and fourth schemes, but the mounting plate in the first scheme and the mounting plate in the fourth scheme refer to different components, that is, the same name but different components. Please understand the respective names in each scheme. There are still some of the above-mentioned components that have the same name but represent different components in the five schemes. Please refer to the above method for the same understanding and processing, and this embodiment will not be illustrated one by one.

[0089] Secondly, regarding the component name label, the component name label of each scheme in the five schemes of the present application is independent of each other and is not mutually quoted. For example, the component name label in the first scheme is only applicable to the first scheme and is not applicable to the second to fifth schemes. Even if the second to fifth schemes have the same label as the first scheme, but the components are different, it has nothing to do with the first scheme. Or the second to fifth schemes have the same component as the first scheme, but the labels are different, which also has nothing to do with the first scheme. As for the second to fifth schemes being the same as the first scheme, the same understanding can be made, and it will not be described in detail. Next, examples will be given to illustrate:

[0090] (1) The fourth and fifth schemes both exist transparent cover plate, but in different schemes, the transparent cover plate is different in different schemes, such as the fourth scheme, the transparent cover plate is 13, the fifth scheme, the transparent cover plate is 70. Therefore, the same components have different labels in different schemes, please use the respective label in each scheme to understand.(2) The first scheme, the fourth scheme both exist cavity, but in different schemes, the moving knife is different in different schemes, such as the first scheme, the cavity is 110, the fourth scheme, the cavity is 11. Therefore, the same components have different labels in different schemes, please use the respective label in each scheme to understand. There are still some of the above-mentioned in the five schemes represent the same part, but the label is different, can refer to the above way to understand and process the same, this embodiment does not one by one example.

[0091] (3) The first scheme and the third scheme both exist label 120, but in different schemes, represent different components. For example, in the first scheme, the label 120 represents the transparent window, and in the third scheme, the label 120 represents the knife head assembly. Therefore, the same label represents different components in different schemes, please use the respective label in each scheme to understand.(4) The second scheme, the fourth scheme and the fifth scheme all exist label 60, but in different schemes, represent different components. For example, in the fourth and fifth schemes, the label 60 represents the circuit board, and in the second scheme, the label 60 represents the sealing cap. Therefore, the same label represents different components in different schemes, please use the respective label in each scheme to understand. There are still some of the above-mentioned in the five schemes have the same label, but represent different components, can refer to the above way to understand and process the same, this embodiment does not one by one example.

[0092] Third, about the drawings, five schemes include 63 drawings, but each scheme has its respective corresponding drawings, the rest of the drawings are irrelevant to the scheme, please don't cross picture reference. For example, the first scheme only corresponds to reference 1-20, other drawings are irrelevant to the first scheme. The second scheme only corresponds to reference 21-38, other drawings are irrelevant to the second scheme. The third scheme only corresponds to reference 39-45, other drawings are irrelevant to the third scheme. The fourth scheme only corresponds to reference 46-55, other drawings are irrelevant to the fourth scheme. The fifth scheme only corresponds to reference 56-64, other drawings are irrelevant to the fifth scheme.

[0093] With the increasing improvement of living standards, more and more male users pay more attention to the quality of life goods. Electric shavers are essential for men in daily life, and the use frequency is very high. After the traditional electric shaver fails, it needs to be disassembled for repair, making it difficult to repair. And more and more users pursue the quality and beauty of electric shavers, and male users generally pursue the mechanical feeling and visual impact of the product. The current shaver cannot meet the needs of users.

[0094] The above content is only used to assist in understanding the technical solutions of the present application, and does not represent the acknowledgement of the above content as prior art.

[0095] In order to solve the above problems, please refer to FIGS. 1-20, the first scheme of the present application proposes a personal care device.

[0096] In the embodiments of the present application, please refer to FIGS. 1-6, the personal care device is an electric shaver, which includes a housing assembly 100 and a linear motor 200; the housing assembly 100 forms a cavity 110, and the housing assembly 100 has a transparent window 120 that can observe the cavity 110; the linear motor 200 is installed in the cavity 110, and the linear motor 200 includes a motor frame 210 and a motor body 220 installed in the motor frame 210, the motor body 220 includes a movable part 221 that can reciprocate relative to the motor frame 210; the movable part 221 is at least partially exposed to the motor frame 210 and corresponds to the transparent window 120.

[0097] In the embodiments, the housing assembly 100 provides installation and protection for the internal structures of the electric shaver, such as the motor, the battery, etc. The output end of the linear motor 200 is connected to the head assembly 400 through an output shaft to drive the moving blade of the head assembly 400 to reciprocate relative to the static blade to achieve hair cutting. The linear motor 200 can be a magnetic levitation linear motor 200, and in other embodiments, it can also be other types of linear motors 200, as long as it can achieve the linear translation motion of the moving blade of the head assembly 400. The use of linear motor 200 in the electric shaver has high precision, fast response, high sensitivity, reliable work, small weight and volume, which is beneficial to realize the miniaturization of the electric shaver. The electric shaver can only use one linear motor 200 to drive the moving blade to move, or can use two linear motors 200, which is not specifically limited here.

[0098] The housing assembly 100 can be made partially or wholly transparent to form the transparent window 120, through which the movement of the linear motor 200 in the cavity 110 can be observed. The transparent window 120 can have various shapes, such as rectangular, circular, strip-shaped, polygonal, irregular, etc., which can be selected and designed according to actual needs, and are not specifically limited herein. The size of the transparent window 120 is also not specifically limited herein, and the size of the transparent window 120 can be designed according to the position and area of the movable part 221 to be observed.

[0099] The linear motor 200 can have various types and forms. The motor frame 210 is used to provide support and mounting for the motor body 220, and the motor frames 210 of different linear motors 200 are different. Some motor frames 210 of the linear motor 200 are frame-shaped structures, some motor frames 210 of the linear motor 200 are suspension arm structures or only have a base, so that the movable part 221 is at least partially exposed to the motor frame 210 to correspond to the transparent window 120. That is, the motor frame 210 does not block or does not completely block the movable part 221 at the position corresponding to the transparent window 120, and the movable part 221 of the motor body 220 can be partially or wholly observed by the transparent window 120. In this way, the user can directly observe the movable part 221 of the motor body 220 through the transparent window 120, that is, the user can directly observe the reciprocating motion of the linear motor 200.

[0100] The movable part 221 of different linear motors 200 can be different. For example, some linear motors 200 only have the movable part 221 including the moving assembly 224 and the leaf spring supporting the moving assembly 224 reciprocating. While some linear motors 200 have the drive assembly 222 suspended on the motor frame 210 by the elastic suspension, so that the drive assembly 222 can also reciprocate to a certain extent. Therefore, the movable part 221 of such linear motor 200 includes the drive assembly 222 and the elastic suspension in addition to the moving assembly 224 and the leaf spring. Of course, there are other types of linear motors 200, which are not described one by one herein, and only the movable part 221 of the linear motor 200 capable of reciprocating at least partially corresponds to the transparent window 120, that is, the reciprocating motion of all or part of the movable part 221 can be observed through the transparent window 120.

[0101] The present application sets the transparent window 120 to make the electric shaver shell assembly 100 to have an observable cavity 110, the linear motor 200 is installed in the cavity 110, the linear motor 200 includes the motor frame 210 and the motor body 220 installed in the motor frame 210, the motor body 220 includes the movable part 221 which can reciprocate relative to the motor frame 210; the movable part 221 is at least partially exposed to the motor frame 210 and is arranged corresponding to the transparent window 120. In this way, the user can observe the reciprocating movement of the movable part 221 of the linear motor 200 in the cavity 110 through the transparent window 120 from the outside of the electric shaver, that is, the normal operation of the linear motor 200 can be observed from the outside, improving the convenience of maintenance; at the same time, the whole electric shaver has stronger mechanical feeling and technological feeling, giving the user a new visual impact and visual experience, thereby greatly improving the competitiveness of the product.

[0102] Specifically, please refer to FIGS. 1-10, the transparent window 120 is arranged on the side wall surface of the shell assembly 100 extending along the reciprocating direction of the movable part 221. Since the movable part 221 of the linear motor 200 reciprocates along the preset direction, the transparent window 120 is arranged on the side wall surface of the shell assembly 100 extending along the reciprocating direction of the movable part 221, compared with being arranged on other side wall surfaces of the shell assembly 100, the reciprocating movement of the movable part 221 can be directly observed from the front, that is, the reciprocating movement observed by the user is along the left-right direction, rather than the front-back direction, to ensure the visual effect.

[0103] In an embodiment, as shown in FIGS. 2-8, the shell assembly 100 includes the shell 130 and the transparent panel 140, the cavity 110 is formed in the shell 130, and the visible window 136 communicating with the cavity 110 is formed on the shell 130; the transparent panel 140 is fixedly connected to the shell 130 and covers the visible window 136 to at least partially form the transparent window 120.

[0104] In the embodiment, the shell 130 can be made of a material with high hardness, such as plastic or metal. The transparent panel 140 can be made of a transparent material, such as glass, quartz or transparent plastic, as long as the movable part 221 of the linear motor 200 can be clearly observed through the transparent panel 140. The transparent panel 140 can be embedded on the outer surface of the shell 130 and fixed to the shell 130. Of course, the transparent panel 140 can be fixed to the outer surface of the shell 130 or the inner surface of the shell 130, or embedded on the periphery of the viewing window 136, as long as the transparent panel 140 can cover the viewing window 136. The transparent panel 140 can cover only the viewing window 136 or the periphery of the viewing window 136. By making the shell assembly 100 include the shell 130 and the transparent panel 140, rather than making the entire shell assembly 100 made of a transparent material, the structural strength and the drop resistance of the product can be improved, and the user's line of sight can be focused on the movable part 221 of the linear motor 200, thereby providing a stronger visual impact to the user.

[0105] In an embodiment, referring to FIGS. 2, 4-7, the top of the shell 130 is provided with an opening, and the top cover 170 is installed at the opening. The motor frame 210 is fixedly connected to the top cover 170. By fixing the linear motor 200 to the top cover 170, the assembly error of the motor 200 can be reduced. It can be understood that since the driving rod of the linear motor 200 passes through the top cover 170, by fixing the linear motor 200 directly to the top cover 170, the connection part of the driving rod and the cutter head of the linear motor 200 can be accurately corresponded, the assembly precision can be improved, and the noise can be reduced. Especially when the electric shaver has multiple cutter heads, the multiple driving rods and the multiple cutter heads can be aligned one by one.

[0106] In an embodiment, as shown in FIGS. 1-10, the shell 130 includes a shell body 131 and a mounting plate 135. The shell body 131 forms a cavity 110 therein, and the shell body 131 is provided with a mounting opening 132. The mounting plate 135 is fixedly connected to the shell body 131 and covers the mounting opening 132. The mounting plate 135 is provided with a viewing window 136. The transparent panel 140 is fixedly connected to the shell body 131 and covers the periphery of the mounting plate 135.

[0107] In the embodiment, the mounting plate 135 and the shell body 131 can be fixedly connected in a manner of bonding, embedding, or the like. Specifically, an embedding groove is formed on the outer surface of the shell body 131, a bottom wall of the embedding groove is provided with the mounting port 132, and the mounting plate 135 is adapted to be embedded in the embedding groove. The transparent panel 140 covers the periphery of the mounting plate 135, so that the area of the transparent panel 140 is greater than the area of the mounting plate 135, so that the transparent panel 140 can completely cover the mounting plate 135. In this way, the transparent panel 140 can cover the mounting plate 135, improve the connection stability of the mounting plate 135 and the shell body 131, and ensure the integrity of the outer surface of the shell 130, and can also increase the transparent area of the whole machine and improve the product texture.

[0108] It can be understood that the size of the mounting port 132 is greater than the size of the visual window 136, and by forming the mounting port 132 on the shell body 131, it is more convenient to perform wiring, installation, and the like on the motor, battery, circuit board, lamp plate, and the like in the shell body 131 from the mounting port 132. In addition, the mounting plate 135 is independent with respect to the shell body 131, and more complex mounting structures, such as buckles, mounting flanges 137 for fixing the transparent baffle 150, and the like, can be arranged on the mounting plate 135, so that the molding and manufacturing of the shell 130 are more convenient. The shape and size of the mounting port 132 can be selected and designed according to actual needs, for example, the mounting port 132 is generally rectangular as a whole, which is not specifically limited here.

[0109] In an embodiment, referring to FIGS. 2, 3, 7 to 11, the accommodating cavity 110 is provided with an indicator light 300, the mounting plate 135 is provided with a light guide hole 138 corresponding to the indicator light 300, the shell assembly 100 further includes a metal plate 160, the metal plate 160 is arranged between the mounting plate 135 and the transparent panel 140, that is, the metal plate 160 covers the side of the mounting plate 135 facing the transparent panel 140, and is arranged away from the visual window 136, and the metal plate 160 is provided with a plurality of light transmission micro-holes 161 corresponding to the light guide hole 138.

[0110] In the embodiment, the accommodating cavity 110 is also provided with an indicator light PCB, which can be fixedly installed on the mounting plate 135. It can be understood that the mounting plate 135 is usually made of plastic material to facilitate the molding of complex structures. Due to the high molecular characteristics and plasticity of plastic, deformation and shrinkage are prone to occur during processing, which makes it difficult to control the shape and size of the micro-holes. By arranging the metal plate 160 and forming a plurality of light transmission micro-holes 161 on the metal plate 160, compared with the mode of directly forming a plurality of light transmission micro-holes 161 on the mounting plate 135, the structural strength can be increased, and the micro-holes formed on the metal plate 160 have higher precision and smoother edges, so that the indication effect of the plurality of light transmission micro-holes 161 is better. The metal plate 160 is arranged away from the visual window 136 to avoid blocking the visual window 136.

[0111] Specifically, a light guide member can be arranged in the light guide hole 138, so that the light emitted by the indicator light 300 via the light guide hole 138 is more concentrated and uniform. The plurality of light transmission micro-holes 161 can form an indicator pattern of switch-on, flight mode, power, etc. By opening the light guide hole 138 on the mounting plate 135 and opening the plurality of light transmission micro-holes 161 on the metal plate 160, the light emitted by the indicator light 300 can be transmitted to the transparent panel 140 via the light guide hole 138 and the plurality of light transmission micro-holes 161, and then observed by the user. The entire machine shell makes full use of the transparent panel 140 to transmit the indicator light, without the need to punch a light transmission hole on the shell 130 and fill a light transmission glue, thereby simplifying the process. Moreover, the user observes the visual effect of the indicator light from the transparent panel 140, which is better.

[0112] In an embodiment, referring to FIGS. 2, 6-20, the shell assembly 100 further includes a transparent baffle 150 arranged inside the transparent panel 140, the transparent baffle 150 being fixedly connected to the mounting plate 135 and covering the visible window 136.

[0113] In the present embodiment, the transparent baffle 150 and the mounting plate 135 can be detachably fixedly connected or non-detachably fixedly connected. The transparent baffle 150 is fixedly connected to the mounting plate 135, so that the transparent baffle 150 can be integrally disassembled with the mounting plate 135, improving the overall assembly efficiency. The transparent baffle 150 can be made of transparent materials such as glass or transparent plastic, and the material of the transparent baffle 150 can be the same as or different from that of the transparent panel 140. It should be noted that even if the transparent baffle 150 is arranged, the user can still observe the linear motor 200 in the cavity 110 through the transparent panel 140 and the transparent baffle 150.

[0114] The transparent baffle 150 can cover the outside of the visible window 136, cover the inside of the visible window 136, or be embedded in the periphery of the visible window 136. By arranging the transparent baffle 150 to cover the visible window 136, dust, lint, etc. in the cavity 110 can be prevented from adhering to the transparent panel 140, affecting the visibility of the transparent panel 140. When the transparent baffle 150 is used to cover the visible window 136, the transparent baffle 150 and the visible window 136 can be contoured to reduce the occupied space of the transparent panel 140 while meeting the dust blocking effect. Alternatively, the transparent baffle 150 is arranged to seal and cover the visible window 136. In this way, the sealing effect of the transparent baffle 150 can be further improved, and dirt such as water vapor, dust, and lint can be prevented from adhering to the inner wall surface of the transparent panel 140.

[0115] In an embodiment, the transparent baffle 150 is spaced apart from the transparent panel 140. Specifically, the transparent baffle 150 is spaced apart from the panel surface of the transparent panel 140 by 3-5 mm. By spacing apart the transparent panel 140 and the transparent baffle 150, even if there is dust on the inner side of the transparent baffle 150, it is not easy to be perceived from the transparent panel 140 on the outside.

[0116] Further, referring again to FIGS. 6-20, the transparent baffle 150 includes a plate body 151 and a surrounding edge 152 extending around the outer periphery of the plate body 151; the mounting plate 135 is provided with a mounting flange 137 surrounding the visual window 136, and the inner peripheral wall of the surrounding edge 152 is lapped on the outer peripheral wall of the mounting flange 137.

[0117] In the present embodiment, the transparent baffle 150 is lapped on the mounting flange 137 surrounding the visual window 136 by the surrounding edge 152, which on one hand can pre-position the assembly of the transparent baffle 150 and the housing 130, increase the mounting area of the transparent baffle 150 and the housing 130, and improve the connection stability of the two, and on the other hand, the surrounding edge 152 and the mounting flange 137 can further improve the sealing of the transparent baffle 150 and the housing 130, so as to further avoid the attachment of water vapor, dust, lint and other dirt on the inner wall surface of the transparent panel 140. In addition, by lapping the transparent baffle 150 on the mounting flange 137 surrounding the visual window 136 by the surrounding edge 152, the spacing between the transparent baffle 150 and the panel surface of the transparent panel 140 can be increased, so as to further reduce the visual impact of the dust on the inner side of the transparent baffle 150 on the transparent panel 140.

[0118] Further, as shown in FIGS. 6-16, opposite sides of the plate body 151 are provided with lugs 153, one of the inner walls of the mounting plate 135 is provided with a clamping hole 154, and the other is provided with a clamping hook 139 matched with the clamping hole 154.

[0119] In the present embodiment, the transparent baffle 150 is clamped and fixed with the mounting plate 135, and the installation is more convenient and stable. By providing the lugs 153 on the two sides of the plate body 151, and providing the clamping hole 154 / clamping hook 139 on the lugs 153, and clamping and matching the clamping hook 139 / clamping hole 154 on the inner wall surface of the mounting plate 135, the surrounding edge 152 does not need to be clamped with the mounting flange 137, the extension height of the mounting flange 137 and the surrounding edge 152 can be reduced, and thus the occupied space of the transparent baffle 150 in the thickness direction can be reduced, so that the whole machine structure can be more compact and small, which is beneficial to the miniaturization of the electric shaver.

[0120] In another embodiment, referring to Figs. 17-20, the surrounding edge 152 is snap-fitted with the mounting flange 137. Snap buckles 154 can be provided on opposite sides of the surrounding edge 152, and snap holes 154 corresponding to the snap buckles are provided on the mounting flange 137, so that the surrounding edge 152 is snap-fitted with the mounting flange 137. The snap-fitting of the surrounding edge 152 with the mounting flange 137 makes full use of the surrounding edge 152 and the mounting flange 137, and eliminates the need for additional lugs 153, thus simplifying the structure of the transparent baffle 150. It will be appreciated that, in order to snap-fit the surrounding edge 152 with the mounting flange 137, the height of the protrusion of the surrounding edge 152 and the mounting flange 137 needs to be set relatively large.

[0121] In an embodiment, referring again to Figs. 1-10, the cross section of the shell body 131 is elongated in the reciprocating direction of the motor body 220, and the shell body 131 has two first side walls 133 opposite in the width direction of the shell body 131, and at least one first side wall 133 is provided with the mounting opening 132.

[0122] In the present embodiment, since the linear motor 200 has a dimension in the reciprocating direction of the output end larger than a dimension in the width direction, the cross section of the shell body 131 is elongated in the reciprocating direction of the motor body 220, so that the motor is mounted while the whole machine is more compact. The mounting opening 132 is provided on the first side wall 133 opposite in the width direction of the shell body 131, i.e., on the side wall with the largest area of the shell body 131, so that the dimension of the mounting opening 132 can be designed larger, and the installation of the internal structure of the shell body 131 is more convenient.

[0123] In an embodiment, the ratio of the area of the transparent panel 140 to the area of the first side wall 133 is greater than or equal to 0.5 and less than or equal to 1. Specifically, the ratio of the area of the transparent panel 140 to the area of the first side wall 133 can be 0.5, 0.6, 0.65, 0.7, 0.8, 0.9, 1, etc. When the ratio of the area of the transparent panel 140 to the area of the first side wall 133 is less than 0.5, the area of the transparent panel 140 is too small, in other words, the area of the mounting opening 132 is too small, which is not conducive to the wiring and installation of the internal structure of the shell 130, and the transparent area of the whole machine is too small, and the product has poor quality. By making the ratio of the area of the transparent panel 140 to the area of the first side wall 133 greater than or equal to 0.5 and less than or equal to 1, the area of the mounting opening 132 can be increased, the wiring and installation of the internal structure of the shell 130 are more convenient, and the transparent area of the whole machine is larger, the visual impact is stronger, and the product has better quality.

[0124] In an embodiment, as shown in FIG. 1, FIG. 2, FIG. 4, FIG. 6, the outer surface of the transparent panel 140 comprises a flat surface 141 and an outer curved surface 142 arranged around the outer periphery of the flat surface 141; the shell body 131 is provided with a mounting groove 134, the bottom wall of the mounting groove 134 is provided with a mounting opening 132, the transparent panel 140 is adapted to be embedded in the mounting groove 134, the flat surface 141 is arranged corresponding to the mounting opening 132, and the outer curved surface 142 is smoothly transitioned with the outer periphery of the shell body 131.

[0125] In the embodiment, the flat surface 141 of the transparent panel 140 corresponds to the mounting opening 132, and the outer curved surface 142 corresponds to the bottom wall of the mounting groove 134, so that the visual effect can be concentrated at the mounting opening 132 rather than the bottom wall of the mounting groove 134, thereby improving the product quality. At the same time, the outer curved surface 142 of the transparent panel 140 is smoothly transitioned with the outer periphery of the shell body 131, which can ensure the overall consistency of the appearance of the whole machine and avoid the situation of being rough.

[0126] In an embodiment, the electric shaver further comprises a light-emitting assembly (not shown) mounted in the cavity 110, and the irradiation area of the light-emitting assembly (not shown) covers the side of the movable part 221 facing the transparent window 120. The light-emitting assembly (not shown) can specifically comprise a stroboscopic lamp. Of course, the light-emitting assembly (not shown) can also comprise an atmosphere lamp, a colored lamp, etc., and the specific type of the light-emitting assembly can be selected and designed according to actual needs, which is not specifically limited here. By providing the light-emitting assembly (not shown) in the electric shaver, the light-emitting assembly (not shown) can irradiate the side of the movable part 221 of the linear motor 200 facing the transparent window 120, so that the side of the movable part 221 of the linear motor 200 directly observed by the user is illuminated, and the user can more clearly observe the reciprocating motion of the linear motor 200 from the outside, so that the visual effect of the electric shaver is more intense.

[0127] Further, the light-emitting assembly (not shown) comprises a stroboscopic lamp, and the ratio of the absolute value of the difference between the movement frequency of the movable part 221 and the flashing frequency of the stroboscopic lamp to the movement frequency of the movable part is greater than 0 and less than or equal to 35%. Specifically, the ratio of the absolute value of the difference between the movement frequency of the movable part 221 and the flashing frequency of the stroboscopic lamp to the movement frequency of the movable part can be 5%, 10%, 15%, 18%, 20%, 25%, 30%, 35%, etc.

[0128] In the embodiment, when the strobe frequency of the strobe light and the motion frequency of the movable part 221 are close, the movable part 221 appears to move slowly although it moves at high speed. By making the ratio of the absolute value of the difference between the motion frequency of the movable part 221 and the strobe frequency of the strobe light to the motion frequency of the movable part greater than 0 and less than or equal to 35%, the user observes the high-speed moving movable part 221 as moving slowly, which is more comfortable and improves the user's visual experience.

[0129] Further, a light-emitting assembly (not shown) is fixed to the wall surface of the cavity 110 adjacent to the transparent window 120. Specifically, the light-emitting assembly (not shown) can be fixed on the housing assembly 100, for example, on the inner wall surface of the mounting plate 135 facing the cavity 110, on the bottom wall, side wall, etc. of the housing body 131, on the motor frame 210 or the mounting plate 135, or on other mounting supports in the cavity, as long as the illumination area of the light-emitting assembly (not shown) covers the side of the movable part 221 facing the transparent window 120.

[0130] In an embodiment, as shown in FIGS. 3-6, the motor body 220 includes a driving assembly 222, a motion assembly 224, an elastic support unit 225, and an elastic suspension unit 226. The two ends of the motion assembly 224 are connected to the driving assembly 222 through the elastic support unit 225, so that the motion assembly 224 can be driven by the driving assembly 222 to move back and forth along a preset direction under electromagnetic action. The two ends of the driving assembly 222 are connected to the motor frame 210 through the elastic suspension unit 226, so that the driving assembly 222, the motion assembly 224, the elastic support unit 225, and the elastic suspension unit 226 form the movable part 221.

[0131] In the embodiment, the motion assembly 224 includes a permanent magnet and a magnet support seat. The permanent magnet is fixed to the magnet support seat. The two ends of the magnet support seat are connected to the driving assembly 222 through an elastic support unit 225. The driving assembly 222 specifically includes an iron core, a bobbin, and a coil 223. The coil 223 is wound on the bobbin and is mounted on the iron core through the bobbin. The iron core can be a U-shaped iron core, an E-shaped iron core, or the like, and different types of iron cores can be selected according to actual needs, which are not specifically limited here. After the coil 223 is passed through alternating currents, the motion assembly 224 forms an electromagnet. Through the magnetic induction action of the electromagnet and the permanent magnet of the driving assembly 222, the driving assembly 222 is driven to move back and forth along a preset direction. In actual use, by connecting the tool head assembly 400 to the connecting seat of the motion assembly 224, the linear motor 200 can drive the blade to move back and forth quickly. The elastic support unit 225 specifically can include a leaf spring or the like, and the elastic suspension unit 226 specifically can include a spring piece, a flexible plate, or the like.

[0132] By connecting two ends of the motion assembly 224 to the driving assembly 222 through one elastic support respectively, and connecting two ends of the driving assembly 222 to the motor frame 210 through the elastic suspension, the driving assembly 222 and the motion assembly 224 are suspended on the motor frame 210 as a whole. Since the weight of the driving assembly 222 is much greater than the weight of the motion assembly 224, the swing of the elastic suspension relative to the frame is smaller, and the damping effect is better. By using this type of linear motor 200, the driving assembly 222 and the elastic suspension unit 226 also form the movable part 221. Since the motion amplitude of the driving assembly 222 and the elastic suspension unit 226 is smaller and the frequency is lower than that of the motion assembly 224 and the elastic support unit 225, a different visual experience can be provided to the user.

[0133] In an embodiment, referring to FIGS. 3, 4 and 6 again, the motor frame 210 is provided with an exposure window 211 corresponding to the elastic support unit 225 and / or the driving assembly 222 on the side wall facing the transparent window 120.

[0134] Since the elastic suspension space needs to be provided for the driving assembly 222, the motor frame 210 is designed as a frame structure. By providing the exposure window 211 on the side wall of the motor frame 210 facing the visual window 136, the elastic support unit 225 and / or the driving assembly 222 can be exposed to the transparent window 120 through the exposure window 211. The user can observe the reciprocating motion of the elastic support unit 225 and the driving assembly 222 through the transparent window 120 and the exposure window 211 of the motor frame 210. In addition, the other parts of the motor frame 210 except the exposure window 211 can block the motor body, so that the motor frame 210 only exposes the part that the user wants to observe, which can further improve the visual experience of the product.

[0135] Further, as shown in FIGS. 2 to 6, the driving assembly 222 includes a mounting seat 227 and a coil 223, the motion assembly 224 is fixedly connected to the mounting seat 227, the upper end of the elastic support unit 225 is fixedly connected to the motion assembly 224, and the lower end is fixedly connected to the mounting seat 227; the lower end of the elastic suspension unit 226 is fixedly connected to the mounting seat 227, and the upper end is fixedly connected to the motor frame 210; the elastic support unit 225 includes a leaf spring, and the exposure window 211 is provided corresponding to the leaf spring and the coil 223.

[0136] In the embodiment, the motion assembly 224 is fixedly connected to the mounting seat 227, and the driving assembly 222 is suspended in the motor frame 210 through the mounting seat 227 and the elastic suspension unit 226. The fixing modes of the elastic support unit 225, the motion assembly 224 and the mounting seat 227, and the fixing mode of the elastic suspension unit 226 and the mounting seat 227 can be screwing, riveting, welding and the like, which are not specifically limited herein. By making the display window 211 correspond to the leaf spring supporting the motion assembly 224 and the coil 223 of the driving assembly 222, different visual experiences can be provided for users due to the different reciprocating forms of the coil 223 and the leaf spring, and thus the product competitiveness can be greatly improved.

[0137] With the increasing demand of consumers for multifunctional and high-performance personal care products, personal care devices such as electric shavers and electric toothbrushes not only need to provide excellent and comfortable care effects, but also need to be safe and reliable when used in water or operated in a wet environment.

[0138] The waterproof performance is crucial for the long-term use and durability of personal care devices. However, in the related art, the charging port design of personal care devices such as electric shavers and electric toothbrushes fails to effectively prevent moisture and humid air from entering, which may cause the risk of circuit short circuit or component corrosion.

[0139] The above content is only used to assist in understanding the technical solutions of the present application and does not represent the acknowledgement of the above content as prior art.

[0140] To solve the above problems, please refer to FIGS. 21 to 38, the second scheme of the present application proposes a personal care device. Personal care devices generally refer to tools or instruments used for daily personal hygiene and beauty care, including but not limited to electric shavers, electric toothbrushes, hair clippers, facial cleaning instruments, etc.

[0141] In the embodiment of the present application, please refer to FIGS. 21 to 23, 29 to 31 and 36 to 38, the personal care device 100 includes a main body shell 10 and a charging assembly 20. The main body shell 10 is provided with a charging jack 11, and the charging assembly 20 is arranged in the main body shell 10 and corresponds to the charging jack 11. The charging assembly 20 includes a sealing bracket 21, a charging interface 22 and a sealing member 23. The charging interface 22 is sealingly fixed to the sealing bracket 21 and exposed to the main body shell 10 through the charging jack 11; the sealing member 23 is arranged around the charging jack 11, and the sealing member 23 is clamped between the main body shell 10 and the sealing bracket 21.

[0142] The main body shell 10 is the outer shell and support structure of the entire personal care device 100, providing a cavity to accommodate the charging assembly 20 and other electronic components, and providing an electrical power interface through the charging jack 11. The charging assembly 20 provides electrical power support for the operation of the personal care device 100. The charging assembly 20 includes a sealing support 21, a charging interface 22, and a sealing member 23. The sealing support 21 cooperates with the main body shell 10 to support or secure the charging interface 22 and the sealing member 23. The charging interface 22 is connected to an external power adapter for charging. The charging interface 22 is exposed to the main body shell 10 through the charging jack 11 for easy user identification and operation. The exposure of the charging interface 22 allows the user to easily identify and connect the charging position without the need to disassemble or open other parts of the personal care device 100, simplifying the operation steps.

[0143] The charging interface 22 is directly or indirectly sealed and fixed to the sealing support 21 to prevent external water or dust from entering the interior of the personal care device 100 through the gap between the charging interface 22 and the sealing. The sealing member 23 is arranged around the charging jack 11 and is clamped between the main body shell 10 and the sealing support 21. This can prevent water and dust from entering the interior of the device through the gap between the charging jack 11, the main body shell 10, and the sealing support 21, thereby improving the water and dust resistance level of the device.

[0144] The double waterproofing is achieved by directly or indirectly sealing and fixing the charging interface 22 to the sealing support 21 and clamping the sealing member 23 between the main body shell 10 and the sealing support 21, thereby significantly improving the water resistance level of the personal care device 100 and reducing the risk of damage to the device due to water ingress. Compared to the sealing structure formed by the multiplex shell or the core support, the independent sealing support 21 can use more precise sealing materials and structures without being limited by the design of the shell or the core support, thereby forming a more flexible or adaptive sealing structure. At the same time, the independent sealing support 21 is convenient for replacement and maintenance. In this way, the user can extend the service life of the personal care device 100 at a lower cost. In addition, the independent sealing support 21 allows the charging assembly 20 in the personal care device 100 to be independently developed and optimized, which helps to simplify the assembly process and improve production efficiency.

[0145] Further, referring to FIGS. 23, 25, 31, 33, and 38, the sealing support 21 is provided with a glue accommodating groove 211, and the glue accommodating groove 211 is provided with an assembly opening 2112 corresponding to the charging jack 11; the charging interface 22 is mounted in the assembly opening 2112; the inner wall surface of the glue accommodating groove 211 and the outer peripheral surface of the charging interface 22 form a glue accommodating space 2111, and the glue accommodating space 2111 is filled with sealing glue.

[0146] In this embodiment, the sealant space 2111 can be filled with sealant. The seal 23 can provide a preliminary waterproof and dustproof effect, and the sealant in the sealant space 2111 can further fill the small gaps that cannot be completely covered by the seal 23, providing a more comprehensive sealing effect. At the same time, the sealant can bond the charging interface 22 and the sealing support 21 after curing, so that the relative positional relationship between the two is maintained, thereby improving the overall structural stability.

[0147] Further, the seal 23 includes a first sealing ring 231a / 231b / 231c extending along the center line direction of the charging jack 11; the inner side of the main shell 10 is provided with a surrounding wall 12 arranged around the charging jack 11; the sealing support 21 is arranged in the surrounding wall 12 near one end of the charging jack 11; and the first sealing ring 231a / 231b / 231c is clamped between the surrounding wall 12 and the sealing support 21.

[0148] In this embodiment, when the sealing support 21 is installed, the surrounding wall 12 can play a positioning role, thereby improving the assembly efficiency. The first sealing ring 231a / 231b / 231c clamped between the surrounding wall 12 and the sealing support 21 prevents external moisture from entering the interior of the personal care device 100 from the gap between the surrounding wall 12 and the sealing support 21.

[0149] Further, referring to FIGS. 36-38, the seal 23 further includes a transverse sealing ring 232c connected to one end of the first sealing ring 231c away from the charging jack 11; the sealing support 21 includes a main body portion 213 and a baffle 215 surrounding the side wall of the main body portion 213; and the transverse sealing ring 232c is clamped between the side of the baffle 215 facing the charging jack 11 and the end surface of the surrounding wall 12 away from the charging jack 11 to seal the gap between the sealing support 21 and the main shell 10.

[0150] In this embodiment, the transverse sealing ring 232c becomes the second barrier against water, and even if the waterproof performance of the first sealing ring 231c decreases or fails, the transverse sealing ring 232c can prevent external water from penetrating into the interior of the personal care device 100 through the gap between the main shell 10 and the sealing support 21.

[0151] Further, the sealing support 21 has a bottom end wall, and the assembly opening 2112 is formed in the bottom end wall; the bottom end wall is further provided with a connecting opening 216, and the inner wall surface of the bottom end wall is further provided with a surrounding plate 217 around the connecting opening 216; the personal care device 100 further includes a sealing cap 60 and a sealing plug 70, the sealing cap 60 includes a cover 61 and a connecting column 62 connected to the inner wall surface of the cover 61, the connecting column 62 is movably arranged in the surrounding plate 217 through the connecting opening 216, so that the cover 61 can open or block the charging jack 11; and the sealing plug 70 blocks one end of the surrounding plate 217 away from the connecting opening 216.

[0152] In the present embodiment, the connecting post 62 of the sealing cap 60 can freely move within the space formed by the ring 217 around the connecting port 216, so that the cover 61 of the sealing cap 60 is conveniently opened or sealed to the charging jack 11. Meanwhile, the sealing plug 70 seals the end of the ring 217 away from the connecting port 216, preventing the sealing glue from flowing into the space in the ring when the sealing glue is filled in the glue filling space 2111, thereby affecting the movement of the connecting post 62.

[0153] In an embodiment, referring to FIGS. 21-33, the charging assembly 20 further comprises a decorative piece 24 mounted on the periphery of the charging jack 11, which is limitedly fitted with the main body shell 10 in the opening direction of the charging jack 11; the decorative piece 24 is sleeved on the outside of the charging interface 22.

[0154] In the present embodiment, the decorative piece 24 is usually made of metal. The decorative piece 24 provides the necessary mechanical support to ensure the stability and durability when the data line interface is inserted. Meanwhile, the inner wall of the decorative piece 24 also provides a guide for the data line interface, facilitating the docking of the data line interface and the charging interface 22.

[0155] Further, referring to FIGS. 21-25, the sealing member 23 further comprises a transverse sealing ring 232a connected to the first sealing ring 231a at the end close to the charging jack 11; the transverse sealing ring 232a comprises a first side and a second side arranged along the direction of the center line of the charging jack 11; the first side abuts against the side of the sealing support 21 facing the charging jack 11; the second side abuts against the main body shell 10 and the decorative piece 24 to seal the gap between the sealing support 21 and the main body shell 10 and the decorative piece 24.

[0156] In the present embodiment, the transverse sealing ring 232a extends in the transverse direction. The transverse direction is perpendicular or intersects with the direction of the center line of the charging jack 11. The transverse sealing ring 232a cooperates with the first sealing ring 231a to enable the sealing support 21 to achieve waterproofing in two directions at the same time.

[0157] In an embodiment, the sealing member 23 comprises a transverse sealing ring 232b connected to the first sealing ring 231b at the end close to the charging jack 11, which is clamped between the sealing support 21 and the main body shell 10.

[0158] In the present embodiment, since the transverse sealing ring 232b is connected to the first sealing ring 231b at the end close to the charging jack 11, it means that additional sealing protection is provided at a key interface (charging jack 11) of the shaver. This helps to prevent moisture or dust from penetrating into the shaver through the charging jack 11 and via the gap between the sealing support 21 and the main body shell 10 during charging, thereby improving the overall waterproof and dustproof performance of the shaver.

[0159] Further, referring to FIGS. 29-33, the seal 23 further comprises a second seal ring 233 extending in the same direction as the first seal ring 231b, the second seal ring 233 being connected to one end of the transverse seal ring 232b away from the first seal ring 231b; the decoration 24 comprises a first positioning section 241 and a seal section 242 connected in the center line direction of the charging jack 11; the first positioning section 241 is limitedly fitted with the main body shell 10 in the opening direction of the charging jack 11; the seal section 242 extends in the center line direction of the charging jack 11, and the second seal ring 233 is clamped between the seal section 242 and the seal support 21.

[0160] In the present embodiment, the second seal ring 233 serves to seal the gap between the seal support 21 and the outer side surface of the decoration 24. On the one hand, it prevents water outside the personal care device 100 from entering the glue containing space 2111 through the gap between the seal support 21 and the outer side surface of the decoration 24. On the other hand, it prevents the sealant from flowing out of the glue containing space 2111 through the gap when the glue containing space 2111 is filled with sealant.

[0161] Since the first positioning section 241 of the decoration 24 is limitedly fitted with the main body shell 10 in the center line direction of the charging jack 11, this precise positioning mechanism helps to reduce assembly errors and improve assembly accuracy. At the same time, the clamping relationship between the seal section 242 and the second seal ring 233 also makes the entire assembly process more simple and fast, thereby improving production efficiency.

[0162] The transverse seal ring 232b, the first seal ring 231b and the second seal ring 233 cooperate to achieve multiple sealing protection, significantly enhancing the sealing performance of the shaver in the charging jack 11 area, effectively preventing external impurities such as moisture and dust from penetrating into the shaver through the gap, thereby improving the waterproof and dustproof level of the product.

[0163] Further, referring to FIGS. 29-33, the decoration 24 further comprises a second positioning section 243 placed in the glue containing groove 211; the second positioning section 243 is limitedly fitted with the inner wall surface of the glue containing groove 211 in the opening direction of the charging jack 11; the second positioning section 243 extends towards the surrounding wall 12 and covers the joint seam between the second seal ring 233 and the seal support 21.

[0164] In the present embodiment, a second positioning segment 243 is added in the trim 24 and is positioned in the glue accommodating groove 211, and is limited and matched with the inner wall surface of the glue accommodating groove 211 in the center line direction of the charging jack 11. This design effectively combines the trim 24 with the main body structure (the main body shell 10, the sealing support 21, etc.) of the shaver more closely. The addition of the second positioning segment 243 not only enhances the positioning accuracy of the trim 24 itself, but also effectively blocks the potential penetration path by covering the joint between the second sealing ring 233 and the sealing support 21, thereby improving the waterproof and dustproof performance of the shaver in the area of the charging jack 11.

[0165] In an embodiment, referring to FIGS. 23, 26-28, 31, 34, 35, and 38, the glue accommodating groove 211 is provided with a mounting opening 2113 corresponding to the assembly opening 2112; the charging assembly 20 further includes a circuit board 30, the circuit board 30 is electrically connected with the charging interface 22, and the circuit board 30 covers the mounting opening 2113; and the circuit board 30 is provided with a glue pouring hole 31.

[0166] The circuit board 30 not only realizes electrical connection with the charging interface 22, the main control board, etc., but also, by covering the mounting opening 2113, forms a glue accommodating space 2111 together with the sealing support 21 and the charging interface 22. The provision of the glue pouring hole 31 allows waterproof glue to be injected between the circuit board 30 and the sealing support 21, further enhancing the waterproof performance of the personal care device 100. In some embodiments, two glue pouring holes 31 are provided on the circuit board 30 and are distributed along the diagonal line of the circuit board 30. In this way, glue injection is facilitated, and the arrangement of multiple electronic elements on the circuit board 30 is also facilitated.

[0167] Further, the side wall of the glue accommodating groove 211 is provided with a boss 2114; the boss 2114 is spaced apart from the end surface of the glue accommodating groove 211 away from the charging jack 11; and the circuit board 30 is fixedly connected to the boss 2114 and is embedded in the glue accommodating groove 211.

[0168] In the present embodiment, the circuit board 30 is fixed with the glue accommodating groove 211 through the boss 2114. The boss 2114 serves as a support structure for the circuit board 30 and can effectively prevent the circuit board 30 from being displaced or loosened under the action of vibration or external force, thereby improving the structural stability and reliability of the entire product. Embedding the circuit board 30 in the glue accommodating groove 211 and fixing it with the aid of the boss 2114 makes full use of the limited space inside the personal care device 100. In this way, not only is the volume of the product reduced, but also the overall aesthetics are improved. At the same time, the boss 2114 is spaced apart from the end surface of the glue accommodating groove 211 away from the charging jack 11, providing sufficient space for the installation and fixation of the circuit board 30 and avoiding interference with other components.

[0169] In some embodiments, the boss 2114 is provided with a fixing hole 2115, and the circuit board 30 is provided with a through hole 32 corresponding to the position of the fixing hole 2115. The fastener 50 is sequentially inserted through the through hole 32 and the fixing hole 2115, so that the circuit board 30 is fixedly connected to the boss 2114. The boss 2114 is spaced apart from the end face of the glue accommodating groove 211 away from the charging jack 11 to form a relief space 212 for accommodating the outer end of the fastener 50. In this way, the stable connection of the circuit board 30 and the glue accommodating groove 211 can be achieved, and the space in the glue accommodating groove 211 can be reasonably optimized. The boss 2114 also plays a role in improving the structural strength in this embodiment.

[0170] In an embodiment, the charging assembly 20 further comprises a sealing ring 25a / 25b, the sealing ring 25a / 25b is sleeved on the charging interface 22, and the outer wall of the sealing ring 25a / 25b abuts against the sealing support 21 or the decorative piece 24.

[0171] The sealing ring 25a / 25b is usually made of elastic material, such as rubber or silicone.

[0172] In some embodiments, the sealing ring 25a forms a seal between the charging interface 22 and the sealing support 21. On the one hand, the sealing ring 25a can prevent moisture or dust from entering the glue accommodating space 2111 from the gap between the charging interface 22 and the sealing support 21. On the other hand, the sealing ring 25a can prevent the waterproof glue from flowing out of the glue accommodating space 2111 from the gap between the charging interface 22 and the sealing support 21.

[0173] In some embodiments, the sealing segment 242 is located outside the sealing ring 25b; the sealing ring 25b is clamped between the sealing segment 242 and the charging interface 22; and the outer peripheral surface of the charging interface 22, the inner wall surface of the sealing support 21, and the side surface of the decorative piece 24 facing away from the charging jack 11 together enclose the glue accommodating space 2111. At this time, the sealing ring 25b seals the gap between the inner side surface of the decorative piece 24 and the outer side surface of the charging interface 22. On the one hand, it prevents external from entering the personal care device 100 from the gap. On the other hand, it prevents the sealant in the glue accommodating space 2111 from flowing out of the gap. In addition, the glue accommodating space 2111 in this embodiment makes full use of the various components. For example, the adhesive effect of the cured sealant keeps the relative positions of the components stable. At the same time, the sealant can fill the small gaps that cannot be blocked by the sealing ring 25b and the sealing member 23.

[0174] In an embodiment, referring to FIG. 22 and FIG. 30, the personal care device 100 further comprises a battery and a mounting bracket 40 arranged in the main body shell 10, the battery is arranged in the mounting bracket 40; and the sealing support 21 is detachably connected to the mounting bracket 40 or the main body shell.

The detachable connection between the sealing bracket 21 and the mounting bracket 40 allows the user or the maintenance personnel to easily remove the sealing bracket 21 from the mounting bracket 40 or the main housing, thereby facilitating the cleaning, maintenance or replacement of the inside of the shaver. This improves the maintainability of the product and prolongs the service life of the product.

[0176] Further, referring to FIG. 31, the side of the mounting bracket 40 facing the charging jack 11 is provided with a clearance groove 41, and the sealing bracket 21 is placed in the clearance groove 41.

[0177] In this embodiment, the clearance groove 41 is designed to allow the sealing bracket 21 to be neatly embedded inside the mounting bracket 40, thereby optimizing the internal layout of the shaver. This layout not only saves space, but also makes the overall structure more compact, which helps to reduce the volume and weight of the shaver. The sealing bracket 21 is placed in the clearance groove 41, which helps to enhance the sealing performance of the shaver in the area of the charging jack 11. The sealing bracket 21 acts as a barrier to effectively block external impurities such as moisture and dust from entering the inside of the shaver, protecting the battery and other electronic components from damage. At the same time, the clearance groove 41 allows the mounting bracket 40 and the charging assembly 20 to be arranged in close proximity, thereby simplifying the wiring and reducing the complexity of the wiring.

[0178] Further, referring to FIGS. 23 and 31, the sealing bracket 21 includes a main body portion 213 and two connecting plates 214 arranged on both sides of the main body portion 213; the main body portion 213 is arranged corresponding to the position of the charging jack 11; and the connecting plates 214 are fixedly connected to the mounting bracket 40 or the main housing.

[0179] In this embodiment, the main body portion 213 and the connecting plates 214 in the sealing bracket 21 have clear functional division. Among them, the main body portion 213 is mainly used for charging and waterproofing, and the connecting plates 214 are used for connection with the mounting bracket 40. This modular design can be adjusted according to different mounting brackets 40 and main housings, improving the efficiency and functionality of the overall design. At the same time, by arranging the connecting plates 214 on both sides of the main body portion 213, the overall weight can be more evenly distributed. When subjected to external force, it can reduce the risk of the personal care device 100 tilting or turning over. And balanced weight distribution can provide a more comfortable grip, reducing user fatigue when using handheld devices.

Secondly, the outer surface of the protrusion 123 is smoothly connected with the outer surface of the limiting stop portion 119, eliminating possible edges and protrusions, making the appearance of the hair trimmer 100 more neat and beautiful. This arrangement not only improves the visual effect of the product, but also improves the user's experience.

[0196] Further, referring to FIGS. 42 and 44, in an embodiment, the annular body portion 122 has a cooperating portion 1221 cooperating with the first limiting portion 111, the cooperating portion 1221 has a top limiting surface 1222 and a side limiting surface 1223 connected to the top limiting surface 1222, the top limiting surface 1222 is convex outward in the first direction relative to the side limiting surface 1223, the top limiting surface 1222 cooperates with the first limiting portion 111 in the longitudinal direction, and the side limiting surface 1223 cooperates with the first limiting portion 111 in the first direction.

[0197] In the present embodiment, the arrangement of the fitting portion 1221 makes the cooperation between the annular body portion 122 and the first limiting portion 111 more compact. The outward protruding arrangement of the top limiting surface 1222 and the side limiting surface 1223 effectively saves space, making the hair trimmer 100 more stable and robust when in use. Secondly, the cooperation between the top limiting surface 1222 and the side limiting surface 1223 of the fitting portion 1221 and the limiting cooperation of the first limiting portion 111 effectively improves the assembly precision between the cutter head assembly 120 and the main machine 110. The outward protruding arrangement of the top limiting surface 1222 ensures the limiting of the main machine shell 113 in the longitudinal direction by the housing 121, so that the cutter head assembly 120 can be accurately positioned during installation, reducing the adjustment and errors during assembly.

[0198] Further, the top limiting surface 1222 and the side limiting surface 1223 are connected to form an arc-shaped guide surface 1224, and the inner side wall of the first limiting portion 111 is adapted to abut against the arc-shaped guide surface 1224; and / or, the thickness of the first limiting portion 111 gradually decreases in the direction of the housing 121.

[0199] In the present embodiment, the arc-shaped guide surface 1224 can effectively guide the position of the cutter head assembly 120 during installation, improving the precision and stability of assembly. It ensures that the cutter head assembly 120 can smoothly enter the correct position during installation, making the installation process of the cutter head assembly 120 more smooth and efficient, reducing the errors and adjustments that may occur during assembly, saving operation time and improving overall efficiency. Secondly, the arc-shaped guide surface 1224 not only guides the position of the cutter head assembly 120, but also enhances the stability of the limiting. It ensures that the inner side wall of the first limiting portion 111 can closely fit the top limiting surface 1222 and the side limiting surface 1223, avoiding possible loosening and displacement, improving the reliability and safety of the hair trimmer 100.

[0200] In addition, by gradually reducing the thickness of the first limiting portion 111 in the direction of the housing 121, the overall size and volume of the hair trimmer 100 can be effectively reduced. Secondly, the part of the first limiting portion 111 away from the housing 121 is arranged to be thicker, and smoothly transitions with the main machine shell 113, which can significantly enhance the structural rigidity of the main machine shell 113, which is beneficial to protect the internal parts of the main machine 110 such as the motor, circuit board, etc. from external impact or vibration, improving the durability and reliability of the hair trimmer 100.

[0201] Further, the arc-shaped guiding surface 1224 and the circumferential surface 1231 of the convex portion are smoothly transitioned in the circumferential direction of the housing 121. This arrangement ensures the accurate guiding of the head assembly 120 during installation, reduces possible friction and resistance, and enables the head assembly 120 to smoothly enter the correct position. If there is a non-smooth surface, it will cause difficulties in aligning the head assembly 120 during installation, increasing the difficulty of the user installing the head assembly 120. In addition, the smooth transition of the arc-shaped guiding surface 1224 and the circumferential surface 1231 of the convex portion makes the installation of the head assembly 120 and the main machine 110 more fitted, reduces the gap between the head assembly 120 and the main machine 110, and makes the appearance of the hair trimmer 100 more beautiful and modern.

[0202] Specifically, the circumferential surface 1231 of the convex portion has a first bottom surface 1232 extending in the first direction and two second arc surfaces 1233 respectively connecting the first bottom surface 1232 and the arc-shaped guiding surface 1224; the second limiting portion 112 is adapted to the circumferential surface 1231 of the convex portion.

[0203] The first bottom surface 1232 is the part of the bottom surface of the convex portion 123 extending in the first direction, which helps to ensure that the convex portion 123 can be adapted to the second limiting portion 112 during installation and maintain a stable installation position. The second arc surface 1233 connects the first bottom surface 1232 and the arc-shaped guiding surface 1224, and the shape of the second arc surface 1233 is adapted to the inner wall surface of the limiting stop portion 119. The second arc surface 1233 is arranged to make the transition between the first bottom surface 1232 and the arc-shaped guiding surface 1224 smooth, and at the same time, the second arc surface 1233 not only ensures the smooth guiding of the head assembly 120 during installation, but also helps to reduce the possible assembly resistance and friction.

[0204] Further, in an embodiment, the outer surface of the annular body portion 122 and the outer surface of the main machine housing 113 are smoothly joined to form the outer surface of the hair trimmer 100.

[0205] In this embodiment, the first limiting portion 111 is a part of the top of the main machine housing 113, which is used to position and limit the installation position of the head assembly 120, and the outer surface of the first limiting portion 111 is smoothly transitioned with the outer surface of the main machine housing 113. The outer surface of the annular body portion 122 forms part of the outer surface of the hair trimmer 100, and the smooth joining of the outer surface of the annular body portion 122 and the outer surface of the main machine housing 113 ensures the unity and integrity of the appearance of the entire hair trimmer 100. The smooth transition and smooth joining arrangement ensures the unity of the appearance of the overall device, making the hair trimmer 100 appear more delicate and modern in appearance.

[0206] In an embodiment, the tool head assembly 120 further comprises a base 124 magnetically connected with the main machine 110, and the housing 121 is annularly arranged on the base 124. The base 124 is provided with a lug 1241 extending towards the top cover 114 at both ends in the second direction, and the second limiting portion 112 is provided with a groove 1123 limiting the lug 1241.

[0207] In the present embodiment, the base 124 is a part of the tool head assembly 120, and its function is to support and fix the position of the tool head assembly 120 on the main machine 110. The base 124 is usually a flat structure for fixedly connecting the tool head and the housing 121. The base 124 is provided with a lug 1241 extending longitudinally towards the top cover 114 at both ends in the second direction. The longitudinal extension of the lug 1241 can make the tool head assembly 120 more compact in the transverse dimension. In contrast, the transverse extension of the lug 1241 may

[0208] Specifically, referring to FIGS. 43 and 44, the second limiting portion 112 has a first limiting surface 1121, the first limiting surface 1121 is arc transitioned with the top wall of the top cover 114 to form a matching surface 1122, the bottom wall of the annular body portion 122 is arc connected with the inner side wall of the convex portion 123 to adapt to the matching surface 1122, and the matching surface 1122 forms the groove 1123.

[0209] In the embodiment, the arc-shaped connection between the bottom wall of the annular body portion 122 and the inner side wall of the convex portion 123 helps to reduce the edges and sharp parts, and reduce the friction and wear that may occur during assembly and use. The first limiting surface 1121 is used to limit the movement of the head assembly 120 in the second direction, and the connection between the bottom wall of the annular body portion 122 and the inner side wall of the convex portion 123 can be matched with the arc-shaped matching surface 1122, which reduces the gap between the shell 121 and the second limiting portion 112, so that the assembly of the head assembly 120 and the main machine 110 is more compact. The groove 1123 is arranged on the matching surface 1122, which further limits the relative position of the head assembly 120 and the main machine 110, and ensures that the head assembly 120 cannot be easily moved or loosened after installation, thereby effectively limiting the movement of the head assembly 120 in the second direction.

[0210] Specifically, referring to FIG. 41, in an embodiment, the base 124 is provided with magnetic pieces 1242 at both ends in the second direction, and the top cover 114 is provided with magnetic pieces 116 that magnetically match the magnetic pieces 1242.

[0211] In the embodiment, the magnetic pieces 1242 can be magnets, metals with magnetism, or other materials with magnetism, and the magnetic pieces 116 can be magnets or other magnetic elements that can be magnetically attracted to the magnetic pieces 1242. The base 124 and the top cover 114 are connected by magnetic attraction to achieve detachable connection of the head assembly 120 and the main machine 110. The magnetic connection provides good fixing force, which can ensure that the head assembly 120 is securely fixed on the main machine 110, avoiding affecting the use effect due to movement or loosening. When disassembled, the magnetic connection allows the head assembly 120 to be easily installed and disassembled without the need for tools, making the operation more convenient for the user.

[0212] The existing electric shaver usually has multiple working modes, and the main body of the electric shaver is usually provided with an indicator light. The indicator light has different lighting modes corresponding to different working modes, so that the user can distinguish the working mode of the electric shaver by checking the lighting mode of the indicator light.

[0213] The existing electric shaver usually sets the indicator light in the shell of the electric shaver, and the shell of the electric shaver is provided with a light transmission hole opposite to the indicator light, and the light transmission hole on the main body is sealed and filled by light transmission glue. However, this scheme brings great inconvenience to the manufacture and use of the electric shaver. Specifically, the light transmission hole needs more complex mold design and manufacturing process, which increases the production complexity and cost. At the same time, it is also necessary to ensure the precision and consistency of the light transmission hole to avoid quality problems. In addition, the sealing glue in the light transmission hole is prone to aging over time, affecting the sealing performance and appearance aesthetics.

[0214] The above merely serves to assist in understanding the technical solutions of the application and does not represent an acknowledgement that the above is prior art.

[0215] To solve the above problems, please refer to FIGS. 46-55, the fourth aspect of the present application provides a personal care device. The personal care device of the present application is an electric shaver. An electric shaver is a power tool specially designed for shaving, usually driven by an electric motor. Its main function is to remove facial hair by vibrating or rotating the head, which has higher efficiency and convenience than traditional razors.

[0216] In the embodiments of the present application, please refer to FIGS. 46-51, the personal care device is an electric shaver 100 / 200, which includes a housing 10, a light source 20, and a light-transmitting indicator plate 30a / 30b. The housing 10 is the external protective structure of the entire electric shaver 100 / 200, which is used to wrap the internal electronic components and mechanical assemblies. The housing 10 can be made of plastic, metal or other materials. The housing 10 has a cavity 11. The cavity 11 is used to accommodate the internal components of the electric shaver 100 / 200, such as the battery, the motor 50, and the circuit board 60. The light source 20 is also placed in the cavity 11. The light source 20 is usually an LED lamp or other types of light-emitting devices, which is used to provide lighting or display functions.

[0217] The light-transmitting indicator plate 30a / 30b is designed to display various states or information, such as battery level, charging status, working mode, etc. A plurality of light-transmitting holes 31 are provided on the light-transmitting indicator plate 30a / 30b to achieve light transmission. These light-transmitting holes 31 can form specific patterns or characters, so that the user can intuitively understand the current state of the electric shaver 100 / 200. The light-transmitting indicator plate 30a / 30b is fixedly connected to the housing 10, and is located between the light source 20 and the transparent window 14.

[0218] The side wall surface of the housing 10 has a transparent window 14. The transparent window 14 refers to a transparent and visible area on the side wall surface of the housing 10. The above-mentioned transparency can be full transparency or semi-transparency. The transparent window 14 can be a part of the housing 10 itself, or it can be another transparent component other than the housing 10, and the component is fixedly connected with the housing 10. The transparent window 14 allows the light emitted by the light source 20 to pass through the light-transmitting holes 31, so that the user can see the patterns or characters displayed on the light-transmitting indicator plate 30a / 30b through the transparent window 14, which is convenient for real-time monitoring of the state of the electric shaver 100 / 200. The transparent window 14 expands the user's observation range, ensuring that the information of the light-transmitting indicator plate 30a / 30b can be clearly visible, while maintaining the aesthetic appearance of the product.

[0219] The application discloses an electric shaver 100 / 200, which comprises a housing 10, a light source 20 and a light-transmitting indication plate 30a / 30b. The housing 10 has a containing cavity 11, and the light source 20 is arranged in the containing cavity 11. The housing 10 is provided with a transparent window 14 on a side wall surface. The light-transmitting indication plate 30a / 30b is provided with a plurality of light-transmitting holes 31, is fixedly connected to the housing 10 and is located between the light source 20 and the transparent window 14, so that the emitted light of the light source 20 can pass through the light-transmitting holes 31 and the transparent window 14 in sequence. The application makes the information conveyed by the light-transmitting indication plate 30a / 30b clear through the transparent window, and omits the complex manufacturing process of ensuring the precision and consistency of the light-transmitting holes 31 and accurately dropping sealing glue in the light-transmitting holes 31, thereby avoiding the adverse consequences of poor sealing effect and appearance caused by aging of the sealing glue.

[0220] Further, referring to FIGS. 47-51, the housing 10 comprises an outer shell 12a / 12b and a transparent cover plate 13. The transparent cover plate 13 can be a fully transparent cover plate or a semi-transparent cover plate. The transparent cover plate 13 can be made of transparent plastic, glass or the like. The outer shell 12a / 12b is provided with a light-transmitting window 121a / 121b. The light-transmitting window 121a / 121b is used to allow light to pass through and plays a positioning role when the transparent cover plate 13 is installed. The transparent cover plate is formed with a transparent window 14, and the light-transmitting indication plate 30a / 30b is located between the light source 20 and the transparent cover plate 13. The transparent cover plate 13 covers the light-transmitting window 121a / 121b and is sealingly connected with the outer shell 12a / 12b, so as to ensure that the internal components of the electric shaver 100 / 200 are not affected by the external environment, such as moisture and dust.

[0221] In some embodiments, the transparent cover plate 13 is a semi-transparent black glass. Compared with the fully transparent outer shell 12a / 12b, the semi-transparent black glass can reduce the direct penetration intensity of light, so that the light of the indicator lamp is softer and the eyes of the user are less stimulated.

[0222] Further, the light-transmitting indication plate 30a / 30b is a metal piece, and a plurality of light-transmitting holes 31 form an indication area. In order to further obtain an appearance aesthetic and an identification pattern with rich information, the light-transmitting holes 31 are designed to be light-transmitting micropores. However, due to the high molecular characteristics and plasticity of plastic, deformation and shrinkage are prone to occur during the processing, so that the shape and size of the micropores are not easy to control. In the embodiment, the light-transmitting indication plate 30a / 30b is a metal piece, and the metal has high hardness and toughness, so that more accurate and stable holes can be obtained when the micropores are opened on the metal. The edges of the micropores of the metal are usually smoother, reducing burrs and unevenness, and being more conducive to light propagation.

[0223] In an embodiment, referring to FIG. 47 and FIG. 51, a first mounting groove 122 is formed on the outer side wall of the housing 12a / 12b, a light-transmitting window 121a / 121b is formed on the bottom wall of the first mounting groove 122, and the transparent cover plate 13 is embedded in the first mounting groove 122. The groove wall of the first mounting groove 122 increases the effective contact area between the transparent cover plate 13 and the housing 12a / 12b, facilitating the formation of an effective seal (such as applying glue) between the first mounting groove 122 and the transparent cover plate 13, and improving the waterproof and dustproof performance of the electric shaver 100 / 200.

[0224] Further, the thickness of the transparent cover plate 13 is greater than the depth of the first mounting groove 122. Moreover, the outer surface of the transparent cover plate 13 is smoothly connected with the outer surface of the housing 12a / 12b. This means that part of the transparent cover plate 13 will protrude out of the first mounting groove 122 after installation. On the one hand, it can increase the stability of the overall structure, preventing the transparent cover plate 13 from loosening or falling off due to uneven stress or external impact after installation. On the other hand, it can prevent the edges of the transparent cover plate 13 from being scratched or worn when falling.

[0225] Further, referring to FIG. 47 and FIG. 48, the housing 12a includes a shell main body 124a and a mounting plate 125a. The shell main body 124a has a light-transmitting window 121a, and the light-transmitting indicator plate 30a covers the light-transmitting window 121a and is fixedly connected with the shell main body 124a. The mounting plate 125a is arranged on the side of the light-transmitting indicator plate 30a away from the transparent cover plate 13, and the mounting plate 125a is provided with a light guide through hole 1251 corresponding to the position of the light source 20.

[0226] In this embodiment, the shell main body 124a provides a frame to fix and protect the light-transmitting window 121a, protecting the internal components from external environment while ensuring the stability and position accuracy of the light-transmitting window 121a. As a passage for light, the light-transmitting window 121a allows light to pass from the light source 20 to the outside or other areas that need illumination, ensuring smooth passage of light through the window and achieving the expected lighting effect. The light-transmitting indicator plate 30a is used to indicate information such as boot status, current gear, Bluetooth connection, etc. The mounting plate 125a is arranged on the side of the light-transmitting indicator plate 30a away from the transparent cover plate 13, ensuring the alignment of the light source 20 with the light-transmitting hole 31 on the light-transmitting indicator plate 30a for optimal light transmission effect. The light guide through hole 1251 optimizes the light guidance of the light source 20, allowing light to pass through the light-transmitting hole 31 uniformly, improving the lighting effect and the use efficiency of the light source 20.

[0227] Further, the side of the light-transmitting indicator plate 30a away from the transparent cover plate 13 is formed with a second mounting groove 311, and the mounting plate 125a is arranged in the second mounting groove 311.

[0228] In this embodiment, the second mounting groove 311 provides a stable support position for the mounting plate 125a. The mounting plate 125a can be more firmly fixed on the light-transmitting indicator plate 30a, reducing the displacement or shaking that may occur during use, thereby improving the stability and durability of the overall structure. The precise positioning of the mounting plate 125a ensures the alignment of the light source 20 with the light-transmitting hole 31 on the light-transmitting indicator plate 30a. This can effectively guide the light through the light-transmitting hole 31, improving the transmission efficiency and lighting effect of the light, and avoiding the deviation of the light source 20 affecting the lighting quality. At the same time, by setting the second mounting groove 311, the mounting plate 125a can be easily slid into or fixed to the predetermined position, simplifying the installation process.

[0229] Further, the electric shaver 100 also has a light guide piece 40a, which includes a light guide part 42 arranged in the light guide through hole 1251.

[0230] In this embodiment, the light is accurately guided to the area of the light-transmitting hole 31 on the light-transmitting indicator plate 30a by the light guide part 42 in the light guide through hole 1251, optimizing the distribution of light and improving the utilization and uniformity of light.

[0231] Further, the mounting plate 125a is provided with a plurality of light guide through holes 1251, and the side of the mounting plate 125a away from the light-transmitting indicator plate 30a is provided with a fixing groove 1252. The light guide piece 40a includes a plurality of light guide parts 42 and a fixing frame 41 connected to the plurality of light guide parts 42, and the fixing frame 41 is embedded in the fixing groove 1252. Each light guide part 42 is arranged in each light guide through hole 1251. Specifically, the fixing frame 41 is generally rectangular, and the plurality of light guide parts 42 are connected to the inner side edges of the fixing frame 41. For example, there are two light guide parts 42, and the two light guide parts 42 are respectively connected to the two opposite inner side edges of the fixing frame 41.

[0232] In this embodiment, by embedding the fixing frame 41 in the fixing groove 1252, each light guide part 42 is arranged in each light guide through hole 1251. In this way, the light guide piece 40a will not be displaced due to vibration or other external forces, thereby maintaining the stability and consistency of the light guide effect.

[0233] In one embodiment, the electric shaver 100 also has a resilient member 70 and a circuit board 60, and the light source 20 is arranged on the circuit board 60. The resilient member 70 is clamped between the mounting plate 125a and the circuit board 60, and the resilient member 70 has a light transmission hole 71 corresponding to the light source 20.

[0234] In this embodiment, the resilient member 70 is plate-shaped, including but not limited to foam, rubber pad, and silicone pad. The resilient member 70 is stably installed in the second mounting groove 311 by elastically pressing the mounting plate 125a, thereby maintaining the position of the light source 20 stable and ensuring that the light of the light source 20 can be effectively transmitted through the light transmission hole 71.

[0235] In an embodiment, referring to FIGS. 49-52, the outer shell 12b comprises a shell body 124b and a mounting plate 125b; the shell body 124b has 121b, the mounting plate 125b covers 121b, and is fixedly connected with the shell body 124b; the light-transmitting indication plate 30b is arranged on the side of the mounting plate 125b facing the transparent cover plate 13, and the light-transmitting indication plate 30b is arranged corresponding to the position of the light source 20; the mounting plate 125b is provided with a light guide through hole 1251 corresponding to the position of the light source 20.

[0236] In the embodiment, the shell body 124b and the mounting plate 125b are separately arranged to facilitate the pre-installation of the transparent cover plate 13, the light-transmitting indication plate 30b, and the mounting plate 125b by the installation personnel, and then the pre-installed product is installed to the shell body 124b. In this way, through the pre-installation of the modularization, potential problems in the installation can be solved in advance, and the risk in the subsequent assembly process can be reduced. In addition, the separate arrangement of the shell body 124b and the mounting plate 125b makes it easier to replace or adjust the mounting plate 125b. If it is necessary to replace, repair, or upgrade the transparent cover plate 13 or the light-transmitting indication plate 30b, the mounting plate 125b can be directly disassembled without affecting the structure of the entire shell body 124b.

[0237] By providing the light guide through hole 1251 on the mounting plate 125b, the light of the light source 20 can be more effectively guided to the target area that needs to be illuminated or irradiated, thereby reducing the scattering and loss of light, and thereby improving the utilization rate of the light source 20.

[0238] Further, referring to FIG. 52, the side of the mounting plate 125b facing the transparent cover plate 13 is recessed to form a third mounting groove 123; the light-transmitting indication plate 30b is embedded in the third mounting groove 123, and the outer surface of the light-transmitting indication plate 30b is lower than or flush with the outer surface of the mounting plate 125b.

[0239] The light-transmitting indication plate 30b is arranged adjacent to the transparent cover plate 13. If the light-transmitting indication plate 30b is installed out of position, it will cause visual distortion, and thus the user cannot accurately obtain the accurate information of the light-transmitting indication plate 30b. If the outer surface of the light-transmitting indication plate 30b is higher than the outer surface of the outer shell 12b, it will cause the installation space of the transparent cover plate 13 to be compressed, and thus cause the transparent cover plate 13 to be installed out of position, not firmly, and have poor sealing effect, and other adverse consequences.

[0240] In the embodiment, the third mounting groove 123 provides accurate installation positioning for the transparent cover plate 13; at the same time, the outer surface of the light-transmitting indication plate 30b being lower than or flush with the outer surface of the mounting plate 125b can ensure that the transparent cover plate 13 can be more easily aligned with the first mounting groove 122 when installed, and will not be installed not tightly or have gaps due to unevenness.

[0241] Further, referring to FIG. 51, the first mounting groove 122 is provided with a fourth mounting groove 1241, and the light-transmitting window 121b is provided on the bottom of the fourth mounting groove 1241; the mounting plate 125b is embedded in the fourth mounting groove 1241. In this way, the structure of the electric shaver 200 is more compact, which is conducive to the miniaturization of the electric shaver 200.

[0242] Further, in some embodiments, referring to FIGS. 52 to 55, the electric shaver 200 further comprises a light guide 40b arranged in the light guide through hole 1251. The light guide 40b can adjust the angle and direction of the light beam, effectively guide the light from the light source 20 to the area of the light-transmitting hole 31 of the light-transmitting indicator plate 30a, and improve the utilization rate and uniformity of the light.

[0243] In some embodiments, referring to FIG. 52, the mounting plate 125b is provided with a plurality of light guide through holes 1251, and the light guide through holes 1251 are arranged at intervals, and the inner diameter of the light guide through hole 1251 gradually decreases from the direction of the cavity 11 to the transparent cover plate 13. Each light guide through hole 1251 can be designed at different positions to reflect different identification patterns or information. In this way, multiple information or functions can be displayed on the same device or surface, enhancing the multifunctionality and application flexibility of the product. At the same time, as the aperture of the light guide through hole 1251 decreases, the diffusion of the light in the transmission process will decrease, making the light more concentrated. In this way, the over-scattering of the light can be avoided, the utilization efficiency of the light can be improved, and the light intensity can be effectively maintained.

[0244] In an embodiment, the electric shaver 100 / 200 further comprises a motor 50 arranged in the cavity 11, and the transparent window 14 corresponds to part or all of the motor 50, so that the motor 50 can be observed through the transparent window 14.

[0245] In this embodiment, the transparent window 14 can not only transmit the information of the light-transmitting indicator plate 30a / 30b inside the electric shaver 100 / 200 to the outside of the electric shaver 100 / 200, but also help the user to obtain the movement information of the motor 50 inside the electric shaver 100 / 200. In this way, the operation and interaction of the electric shaver 100 / 200 become more simple and natural.

[0246] The care device is usually provided with multiple indicators to indicate that the care device is in the state of starting, charging, Bluetooth opening, etc. Each indicator needs to be provided with a separate light guide component to ensure uniform distribution of light and improve the visibility and clarity of the indicator. In the related art, multiple light guides are independent of each other and are installed separately. The small volume of the light guide and the small volume of the care device result in limited assembly space and limited freedom and flexibility of operation. The separate installation of multiple light guides further increases the assembly difficulty and reduces the assembly efficiency.

[0247] The above merely serves to assist in understanding the technical solutions of the application and does not represent an acknowledgement that the above is prior art.

[0248] To solve the above problems, please refer to FIGS. 56-64, the fifth aspect of the present application proposes a personal care device. The personal care device is a handheld care device. The handheld care device refers to a personal care portable device that can be held and operated by a user, which is usually used for daily personal hygiene and beauty care, including but not limited to an electric toothbrush, an electric shaver, a hair clipper, a facial cleanser, etc.

[0249] In the embodiments of the present application, please refer to FIGS. 56-64, the personal care device is a handheld care device, which includes a housing 10 and a light source 20, a light guide 30, and a light isolation piece 40 arranged in the housing 10. The housing 10 provides overall structural support and protection for the internal components such as the light source 20 and the light guide 30. The light source 20 is used to emit light to illuminate the light-transmitting indication mark 11. The light guide 30 is responsible for effectively guiding the light emitted by the light source 20 onto the light-transmitting indication mark 11. The light isolation piece 40 is used to avoid interference and mixing of light.

[0250] The housing 10 is provided with a plurality of light-transmitting indication marks 11 arranged at intervals. The light-transmitting indication mark 11 is used to convey information such as booting, charging, and Bluetooth connection. The light-transmitting indication mark 11 is usually composed of a plurality of light-transmitting micropores, which not only indicate information but also obtain aesthetic appearance. The light source 20 includes a plurality of light-emitting elements 21 corresponding to the light-transmitting indication marks 11; the light guide 30 and the light isolation piece 40 are located between the light-transmitting indication marks 11 and the light source 20.

[0251] The light guide 30 includes a fixing frame 31 and a plurality of light guide portions 32 integrally connected to the fixing frame 31. The fixing frame 31 is connected to the light isolation piece 40; the light isolation piece 40 has a plurality of light transmission holes 41, each light-emitting element 21 corresponds to a light transmission hole 41, each light guide portion 32 corresponds to a light transmission hole 41, and the light guide portion 32 is arranged in the light transmission hole 41.

[0252] The integral connection includes not only the case where the fixing frame 31 and the light guide portion 32 are integrally formed, but also the case where the fixing frame 31 and the light guide portion 32 are integrally connected by bonding, clamping, etc. Compared with the case where a plurality of independent light guides are respectively mounted into each light transmission hole 41, the light guide 30 in the present embodiment has a relatively large volume, which is easy to be grabbed and positioned by a human hand or assembly tool, reducing the errors and required accuracy that may occur in the assembly process. At the same time, the light guide 30 is more easily compatible with automated assembly, and the larger volume is easy to be recognized and operated by automated equipment such as a robot arm.

[0253] The application comprises a shell 10, a light source 20, a light guide 30 and a light isolation piece 40 arranged in the shell 10. The shell 10 is provided with a plurality of light-transmitting indication marks 11 arranged at intervals. The light source 20 comprises a plurality of light-emitting elements 21 corresponding to the light-transmitting indication marks 11. The light guide 30 and the light isolation piece 40 are located between the light-transmitting indication marks 11 and the light source 20. The light guide 30 comprises a fixing frame 31 and a plurality of light guide portions 32 integrally connected to the fixing frame 31. The fixing frame 31 is connected to the light isolation piece 40. The light isolation piece 40 has a plurality of light transmission holes 41. Each light-emitting element 21 corresponds to one light transmission hole 41. Each light guide portion 32 corresponds to one light transmission hole 41, and the light guide portion 32 is arranged in the light transmission hole 41. The fixing frame 31 and the plurality of light guide portions 32 integrally connected to the fixing frame 31 increase the volume of the light guide 30, which makes the light guide 30 easy to be grabbed or positioned, thereby reducing the assembly difficulty of the light guide 30 and improving the assembly efficiency of the light guide 30.
