Abstract
Description
shaver Technical Field
[0001] This utility model belongs to the field of personal care equipment technology, and specifically provides a razor. Background Technology
[0002] As a common personal care appliance, shavers are widely used in people's daily lives. Traditional shavers typically consist of a body and a shaving head. The body houses components such as the battery and motor, while the shaving head enables the shaving function. To facilitate user operation and allow them to understand the shaver's working status, some shavers have indicator lights on the body to display information such as battery level, charging status, and fault warnings.
[0003] In existing technology, indicator lights are generally installed inside the casing of the device. To allow light to pass through, the casing is usually provided with a light-transmitting window aligned with the indicator light, so that the light emitted by the indicator light can pass through the light-transmitting window.
[0004] However, in existing technologies, to avoid light attenuation from the indicator lights, they are typically mounted close to the casing, limiting their installation location. Furthermore, the indicator lights on current shavers offer a limited display effect and a poor user experience, failing to meet users' demands for a superior visual experience. Summary of the Invention
[0005] One objective of this invention is to solve the problem that the installation position of the indicator light in existing shavers is limited and the display experience is poor.
[0006] To achieve the above objectives, this utility model provides a razor, including a body and a razor head, wherein the body includes:
[0007] The casing, at least part of it, is translucent;
[0008] Indicator lights are located inside the housing;
[0009] A reflective component is disposed inside the housing to reflect the light emitted by the indicator light to the light-transmitting portion of the housing;
[0010] The light-transmitting portion of the housing and / or the reflective component are provided with a light pattern forming structure so that the light emitted by the indicator light forms a light pattern on the housing.
[0011] Optionally, the light pattern forming structure is a groove structure formed on the outer peripheral surface of the reflective member.
[0012] Optionally, the groove structure is a spiral groove or multiple annular grooves spaced apart.
[0013] Optionally, the light pattern forming structure is a concave-convex structure formed on the outer peripheral surface of the reflective member.
[0014] Optionally, at least a portion of the reflective member is configured as a cone with its smaller end facing the indicator light, so that the reflective member reflects the light emitted by the indicator light to the light-transmitting portion of the housing through the cone-shaped portion; the light pattern forming structure is formed at the cone-shaped portion of the reflective member.
[0015] Optionally, at least a portion of the reflective member is tapered.
[0016] Optionally, the light-transmitting portion of the housing is located at the top of the housing, the indicator light is disposed at the top of the housing, and the reflective component is disposed on the top side of the indicator light.
[0017] Optionally, the housing further includes a top cover and a sealing member. The top cover is disposed at the top of the housing, and the sealing member is disposed between the indicator light and the reflective member. At least a portion of the sealing member is light-transmitting to ensure that the light emitted by the indicator light illuminates the reflective member. The top cover abuts against the top end of the reflective member, and the sealing member abuts against the bottom end of the reflective member to fix the reflective member and improve the structural strength of the sealing member, the reflective member, and the top cover.
[0018] Optionally, the housing includes an outer shell and an inner shell located within the outer shell, the top end of the inner shell being located inside the outer shell, so that the housing is fixedly connected to the top cover through the outer shell, and the housing is sealed to the sealing member through the inner shell; a light-transmitting portion on the housing is formed on the portion of the outer shell located on the top side of the inner shell; the indicator light is located on the bottom side of the top end of the inner shell.
[0019] Optionally, the body further includes a fixed bracket disposed within the housing and a light panel mounted on the fixed bracket; the light panel is located on the side of the fixed bracket near the reflector, and the indicator light is mounted on the side of the light panel near the reflector; the light panel abuts against the sealing member.
[0020] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by providing a reflective component inside the housing to reflect the light emitted by the indicator light to the light-transmitting part of the housing, the indicator light no longer needs to be flush against the housing, allowing for more installation positions. By providing a light pattern forming structure on the light-transmitting part of the housing and / or the reflective component, the light emitted by the indicator light can form a light pattern on the housing, optimizing the display experience of the shaver's indicator light.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0053] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection of two components.

[0054] As shown in Figures 1 to 3, in some embodiments of this utility model, the shaver 001 includes a body 100 and a blade head 200.
[0055] In some embodiments of this utility model, the body 100 houses all or most of the electronic components of the shaver 001, and the shaving head 200 houses the blades. The connection between the body 100 and the shaving head 200 enables the body 100 to transmit power to the shaving head 200, driving the blades to rotate, thereby achieving the shaving function.
[0056] Those skilled in the art should understand that, depending on the type of shaver 001, the movement of the blades when driven by the power of the body 100 will also differ. For example, some shaver 001 blades move in a rotating manner to shave the user; others shaver 001 blades move in a reciprocating motion to shave the user.
[0057] The fuselage 100 of some embodiments of the present invention will now be described in detail with reference to Figures 4 to 14.
[0058] As shown in Figures 4 to 10, in some embodiments of this utility model, the body 100 includes a housing 110, a fixed bracket 120, a drive motor 131, a drive gear 132, a transmission gear 141, a transmission shaft 142, a top cover 150, a sealing component 160, an indicator light 171, a reflective component 180, a battery 191, and a controller 192.
[0059] Furthermore, in other embodiments of this utility model, those skilled in the art can omit at least one of the following components as needed: housing 110, fixing bracket 120, drive motor 131, drive gear 132, transmission gear 141, transmission shaft 142, top cover 150, sealing member 160, indicator light 171, reflector 180, battery 191, and controller 192. For example, drive gear 132, transmission gear 141, and / or battery 191 can be omitted. When drive gear 132 and transmission gear 141 are omitted, drive motor 131 can be directly and circumferentially fixedly connected to transmission shaft 142.
[0060] As shown in Figures 5 to 10, in some embodiments of the present invention, the housing 110 may include an outer shell 111 and an inner shell 112 located inside the outer shell 111, and the top of the inner shell 112 is located on the bottom side of the top of the outer shell 111, that is, the top of the inner shell 112 is located inside the outer shell 111, so as to hide the inner shell 112 through the outer shell 111.
[0061] The inner circumferential surface of the outer shell 111 and the outer circumferential surface of the inner shell 112 can directly abut or indirectly abut. When the two abut indirectly, a rib can be provided on one of the inner circumferential surfaces of the outer shell 111 and the outer circumferential surface of the inner shell 112, so that the rib abuts against the other of the inner circumferential surfaces of the outer shell 111 and the inner shell 112.
[0062] As shown in Figures 5 to 13, in some embodiments of this utility model, the fixing bracket 120 is disposed inside the housing 110 and is located entirely on the bottom side of the top of the inner housing 112. The fixing bracket 120 is used to install or fix the drive motor 131, drive gear 132, transmission gear 141, transmission shaft 142, indicator light 171, battery 191, and controller 192.
[0063] Referring again to Figures 5 to 13, in some embodiments of this utility model, the fixing bracket 120 has a top mounting cavity (not marked in the figure) and a bottom mounting cavity (not marked in the figure). The top mounting cavity is used to mount the drive motor 131, and the bottom mounting cavity is used to mount the battery 191.
[0064] Furthermore, the mounting bracket 120 has a through hole (not marked in the figure) on the top side of the top mounting cavity, allowing the shaft of the drive motor 131 to pass through, so that the exposed shaft of the drive motor 131 can be connected to the drive gear 132.
[0065] As shown in Figures 5 to 10, 12 and 13, in some embodiments of this utility model, the top of the fixing bracket 120 is further provided with a shaft hole 121 for mounting the drive shaft 142 and a recess 122 located outside the shaft hole 121. The recess 122 is used to avoid a part of the drive gear 141 and can be set to be tapered.
[0066] As shown in Figures 5 to 10 and Figure 12, in some embodiments of this utility model, the transmission gear 141 meshes with the drive gear 132.
[0067] Furthermore, in other embodiments of this utility model, those skilled in the art may, as needed, provide other gears between the transmission gear 141 and the drive gear 132, and transmit power through these other gears. For example, a gear may be provided between the transmission gear 141 and the drive gear 132, and this gear may mesh with both the transmission gear 141 and the drive gear 132 respectively.
[0068] As shown in Figures 6, 8, and 10, in some embodiments of this utility model, a friction ring 1411 may be provided on the side of the transmission gear 141 facing the fixed bracket 120, so that the transmission gear 141 slides in contact with the fixed bracket 120 through the friction ring 1411. The friction ring 1411 can be made of a wear-resistant material, such as ceramics, graphene, alloys, etc.
[0069] Furthermore, the friction ring 1411 can be tapered and adapted to fit the groove 122 on the fixed bracket 120, so that the fixed bracket 120 slides in contact with the friction ring 1411 through the peripheral wall of the groove 122, thereby increasing the contact area between the friction ring 1411 and the fixed bracket 120. In this way, not only can the friction between the transmission gear 141 and the fixed bracket 120 be improved, but the wear resistance between the friction ring 1411 and the fixed bracket 120 can also be enhanced.
[0070] As shown in Figures 5 to 10, in some embodiments of this utility model, the drive shaft 142 is rotatably inserted into the shaft hole 121 so that the drive shaft 142 is rotatably mounted on the fixed bracket 120. The drive shaft 142 is fixedly connected to the drive gear 141 and is connected to the cutter head 200 to transmit the power generated by the drive motor 131 to the cutter head 200.
[0071] Referring to Figures 5 to 10, in some embodiments of this utility model, the transmission shaft 142 and the transmission gear 141 can be coaxially fixedly connected by an interference fit, or they can be coaxially fixedly connected by welding, bonding, keyway fit, or other methods.
[0072] Furthermore, the drive shaft 142 is buoyant relative to the fixed bracket 120 along its axial direction, so that the drive gear 141 can contact or separate from the fixed bracket 120 as the drive shaft 142 floats, thereby making sliding contact with the fixed bracket 120 when the cutter head 200 is squeezed, increasing the load on the drive motor 131.
[0073] As shown in Figure 6, in some embodiments of this utility model, the maximum floating distance H of the transmission gear 141 relative to the fixed bracket 120 is any value from 0.1mm to 5mm. Specifically, the maximum floating distance H can be 0.1mm, 0.2mm, 0.5mm, 1mm, 1.5mm, 2mm, 3mm, 5mm, etc.
[0074] Furthermore, the maximum floating distance H of the transmission gear 141 relative to the fixed bracket 120 is any value between 0.2 mm and 1 mm. Specifically, the maximum floating distance H can be 0.2 mm, 0.5 mm, 0.8 mm, 1 mm, etc.
[0075] Those skilled in the art will understand that by setting the maximum floating distance H of the transmission gear 141 relative to the fixed bracket 120 to any value between 0.1 mm and 5 mm, particularly any value between 0.2 mm and 1 mm, the response rate of the transmission gear 141 to changes in shaving force is ensured. This avoids situations where the action of the transmission gear 141 is not timely enough, preventing the user from being unable to promptly perceive the shaving force and thus avoiding skin damage from the razor 001.
[0076] As shown in Figures 5 to 10, in some embodiments of this utility model, the body 100 may further include an elastic member 144, which is used to provide a force to the transmission gear 141 away from the fixed bracket 120, so as to separate the transmission gear 141 from the fixed bracket 120.
[0077] As shown in Figures 6, 8, and 10, the elastic member 144 is installed in the shaft hole 121. To prevent negative pressure from being generated in the shaft hole 121 during the axial movement of the drive shaft 142, the fixed bracket 120 is also provided with a pressure equalization hole (not marked in the figure) penetrating the bottom wall of the shaft hole 121. The elastic member 144 is located between the bottom wall of the shaft hole 121 and the drive shaft 142, and is provided with an axial hole penetrating it to accommodate the pressure equalization hole.
[0078] In some embodiments of this utility model, the elastic member 144 can be a rubber ring, a compression spring, or any feasible structure.
[0079] As shown in Figures 5 to 10, in some embodiments of this utility model, the machine body 100 further includes a first insertion shaft 143 circumferentially fixedly connected to the drive shaft 142, so that the machine body 100 is drivenly connected to the cutter head 200 through the first insertion shaft 143. Further, the first insertion shaft 143 and the drive shaft 142 are circumferentially fixed together by insertion and interference fit.
[0080] As shown in Figure 3, in some embodiments of this utility model, the cutter head 200 includes a second plug-in shaft 210 adapted to the first plug-in shaft 143, so that the cutter head 200 is plugged into the first plug-in shaft 143 on the machine body 100 through the second plug-in shaft 210.
[0081] As shown in Figures 4 to 10, in some embodiments of this utility model, the top cover 150 is disposed on the top of the housing 110 and is fixedly connected to the housing 110 to shield components such as the reflective component 180.
[0082] Specifically, the top cover 150 is disposed at the top of the outer casing 111 and is fixedly connected to the outer casing 111. Furthermore, the top cover 150 is provided with a clearance hole 151 aligned with the first insertion shaft 143, so that the second insertion shaft 210 passes through the clearance hole 151 and is inserted into the first insertion shaft 143.
[0083] As shown in Figures 5 to 10, in some embodiments of this utility model, the sealing member 160 is arranged inside the housing 110 and together with the housing 110 defines an electrical cavity 101. The sealing member 160 is spaced apart from the top cover 150 and together with the housing 110 and the top cover 150 defines a protective cavity 102.
[0084] Specifically, the housing 110 is sealed to the sealing member 160 via the inner housing 112, so that the outer housing 111, the sealing member 160 and the top cover 150 together define the aforementioned protective cavity 102, and the inner housing 112 and the sealing member 160 together define the aforementioned electrical cavity 101.
[0085] Those skilled in the art will understand that by arranging the sealing member 160 within the housing 110 and spacing it from the top cover 150, thus defining a protective cavity 102 together with the housing 110 and the top cover 150, the sealing member 160 and the top cover 150 are separated by the protective cavity 102. In this way, when the shaver 001 is bumped or dropped, even if the connection between the top cover 150 and the housing 110 deforms or cracks, the sealing member 160 will not be affected, thereby ensuring the sealing effect of the sealing member 160 on the body 100. Simply put, when the shaver 001 of this invention deforms or cracks at the connection between the top cover 150 and the housing 110 due to bumps or drops, moisture can only enter the protective cavity 102 and cannot enter the electrical cavity 101, ensuring the safety of the electronic components inside the electrical cavity 101.
[0086] As shown in Figure 6, in some embodiments of this utility model, the ratio of the thickness D1 of the protective cavity 102 to the thickness D2 of the sealing member 160 is selected from any value from 2 to 10, so that the sealing member 160 is sufficiently far from the top cover 150 and the protective cavity 102 does not excessively encroach on the space of the body 100. For this purpose, the ratio of D1 to D2 can be any feasible value such as 2, 3, 5, 7, 8, 10, etc.
[0087] As can be seen from Figures 5 to 10, the drive motor 131, drive gear 132, indicator light 171 and battery 191 are all arranged in the electrical cavity 101, and the indicator light 171 is located on the bottom side of the top of the inner shell 112; the first plug shaft 143 is arranged in the protective cavity 102.
[0088] As can be seen from Figures 5 to 10, the drive shaft 142 passes through the sealing member 160 and is in sealing contact with the sealing member 160. The drive shaft 142 is connected to the drive motor 131 and the cutter head 200 respectively to transmit the power of the drive motor 131 to the cutter head 200.
[0089] In some embodiments of this utility model, the sealing member 160 may be made entirely of an elastic material, such as rubber, silicone, latex, etc. Alternatively, the sealing member 160 may be made only of an elastic material at its circumferential edges, with the interior made of a rigid material, such as metal, acrylic, plastic, etc.
[0090] Furthermore, in some embodiments of this utility model, the light color and / or flashing frequency (referred to as light information) of the indicator light 171 changes with the load of the drive motor 131, so as to more intuitively remind the user whether the shaving force is appropriate through the light information emitted by the indicator light 171.
[0091] In practical applications, the light information (light color and / or flashing frequency) of indicator light 171 can be recorded in the instruction manual of shaver 001, so that users can understand the shaving intensity corresponding to different light information by reading the instruction manual, and determine whether the shaving intensity is too low or too high when using shaver 001 based on the different light information.
[0092] Furthermore, although not explicitly shown in the figures, in some embodiments of this utility model, there are multiple indicator lights 171, which are evenly arranged along the circumference of the housing 110 on the inner side of the inner shell 112.
[0093] Referring again to Figures 5 through 10, in some embodiments of this invention, the housing 100 may further include a light panel 172 mounted on a fixed bracket 120. The light panel 172 is located on the side of the fixed bracket 120 near the reflector 180, and an indicator light 171 is mounted on the side of the light panel 172 near the reflector 180. The light panel 172 may also abut against a sealing member 160 to limit the distance the sealing member 160 is inserted into the inner housing 112.
[0094] Furthermore, although not explicitly shown in the figures, in some embodiments of this utility model, the lamp panel 172 and the fixing bracket 120 can be fixed together by means of clips, screws, etc.
[0095] Of course, in other embodiments of this utility model, those skilled in the art will understand that the lamp board 172 is omitted and the indicator light 171 is directly installed on the fixed bracket 120.
[0096] As shown in Figures 5 to 11, in some embodiments of this utility model, the reflective component 180 is disposed inside the housing 110 to reflect the light emitted by the indicator light 171 onto the housing 110.
[0097] As can be seen from Figures 5 to 10, the sealing member 160 is disposed between the indicator light 171 and the reflector 180. Therefore, in order to ensure that the light emitted by the indicator light 171 can illuminate the reflector 180, at least a portion of the sealing member 160 is light-transmitting (not marked in the figure) so that the light emitted by the indicator light 171 can illuminate the reflector 180 through the light-transmitting portion on the sealing member 160.
[0098] Furthermore, in order to ensure that light can pass through the housing 110, at least a portion of the housing 110 is also light-transmitting (not marked in the figure) so that the light reflected by the reflector 180 passes through the light-transmitting portion of the housing 110 and is seen by the user.
[0099] As shown in Figures 5 to 10, in some embodiments of this utility model, the light-transmitting portion of the housing 110 is located at the top of the housing 110, the indicator light 171 is disposed at the top of the housing 110, and the reflective component 180 is disposed on the top side of the indicator light 171.
[0100] Specifically, the light-transmitting portion on the housing 110 is formed on the portion of the outer shell 111 located on the top side of the inner shell 112, that is, at least a portion of the outer shell 111 located on the top side of the inner shell 112 is light-transmitting, so that light passes through the light-transmitting portion of the outer shell 111 located on the top side of the inner shell 112.
[0101] Furthermore, the outer shell 111 is partially translucent on the top side of the inner shell 112, so as to hide the structure inside the outer shell 111 through the translucent structure and optimize the aesthetics of the body 100.
[0102] In addition, in other embodiments of this utility model, those skilled in the art may, as needed, make at least a portion of the top cover 150 transparent so that the light emitted by the indicator light 171 can pass through the housing 111 and the top cover 150.
[0103] As shown in Figures 5 to 10, in some embodiments of this utility model, the sealing member 160 abuts against the bottom end of the reflective member 180, and the top cover 150 abuts against the top end of the reflective member 180 to fix the reflective member 180 and improve the structural strength of the sealing member 160, the reflective member 180 and the top cover 150.
[0104] As can be seen from Figures 5 to 10, in some embodiments of this utility model, the reflective member 180 can be fixedly connected to the sealing member 160 by screws, and the reflective member 180 can also be inserted into the top cover 150 to connect the sealing member 160, the reflective member 180 and the top cover 150 into a whole.
[0105] The connection between the reflective component 180 and the top cover 150 is such that the reflective component 180 has an annular baffle on the side facing the top cover 150, and the top cover 150 has an annular protrusion extending toward the reflective component 180, so that the reflective component 180 and the top cover 150 are connected together through the annular baffle and the annular protrusion.
[0106] As shown in Figures 5 to 11, in some embodiments of the present invention, at least a portion of the reflective member 180 is configured as a cone with its small end facing the indicator light 171, so that the reflective member 180 reflects the light emitted by the indicator light 171 to the light-transmitting portion of the housing 110 through the cone-shaped portion.
[0107] As can be seen from Figures 5 and 6, at least a portion of the reflective component 180 is tapered to accommodate the ergonomic design of the fuselage 100.
[0108] As shown in Figure 6, in some embodiments of the present invention, the taper α of at least a portion of the reflective member 180 is selected from any value between 30° and 80°, such as 30°, 33°, 45°, 50°, 65°, 75°, 80°, etc.
[0109] Furthermore, the taper α of at least a portion of the reflective member 180 is selected from any value between 45° and 65°, such as 45°, 48°, 55°, 61°, 65°, etc.
[0110] Those skilled in the art will understand that by selecting the taper α of at least a portion of the reflector 180 from any value between 30° and 80°, and particularly from any value between 45° and 65°, it is possible to ensure that the reflector 180 reflects the light emitted by the indicator light 171 to the light-transmitting portion at the top of the housing 110.
[0111] As shown in Figures 8 to 11 and 14, in some embodiments of this utility model, the reflective member 180 is further provided with a light pattern forming structure 181 so that the light emitted by the indicator light 171 forms a light pattern on the housing 110.
[0112] Furthermore, in other embodiments of this utility model, those skilled in the art can also, as needed, provide the light pattern forming structure 181 on the housing 110, specifically in the area of the outer shell 111 located at the top of the inner shell 112. The light pattern forming structure 181 can also be provided on both the housing 110 and the reflective member 180 simultaneously.
[0113] As can be seen from Figures 8 to 11 and Figure 14, in some embodiments of this utility model, the light pattern forming structure 181 is a groove structure formed on the outer peripheral surface of the reflective member 180.
[0114] Furthermore, the groove structure is a spiral groove or multiple annular grooves spaced apart.
[0115] Furthermore, in other embodiments of this invention, the light pattern forming structure 181 may also be a concave-convex structure formed on the outer peripheral surface of the reflective member 180. For example, a plurality of evenly distributed protrusions or grooves may be provided on the outer peripheral surface of the reflective member 180.
[0116] As shown in Figures 5 to 11, in some embodiments of this utility model, the battery 191 is mounted on the fixed bracket 120 and located below the drive motor 131. The battery 191 is used to supply power to components such as the drive motor 131 and the indicator light 171.
[0117] As shown in Figure 5, in some embodiments of this utility model, the controller 192 is mounted on the fixed bracket 120, and the controller 192 can be a circuit board, an integrated circuit chip, a combination of multiple electronic components, or any other feasible electronic component or combination of electronic components.
[0118] In some embodiments of this utility model, the controller 192 is used to detect the load of the drive motor 131 and to make the light color and / or flashing frequency (light information) of the indicator light 171 change with the load of the drive motor 131.
[0119] Furthermore, in some embodiments of the present invention, the controller 192 is configured to keep the output speed of the drive motor 131 constant and increase the current of the drive motor 131 as the load increases, so as to determine the load of the drive motor 131 by detecting the current of the drive motor 131.
[0120] Furthermore, the controller 192 can control the shaver 001 to perform the following functions:
[0121] When the current of the drive motor 131 is less than the first preset value, the indicator light 171 outputs light of the first color.
[0122] When the current of the drive motor 131 is greater than or equal to the first preset value, the indicator light 171 outputs a second color light.
[0123] The first preset value can be in the range of 0.3A to 0.8A, and a further range can be 0.4A to 0.7A, specifically 0.3A, 0.4A, 0.45A, 0.7A, 0.8A, etc.
[0124] The first color can be any feasible color such as white, green, or blue.
[0125] The second color can be any feasible color such as yellow or red.
[0126] Furthermore, the controller 192 can also control the shaver 001 to perform the following functions:
[0127] When the current of the drive motor 131 is greater than or equal to the first preset value, the indicator light 171 flashes.
[0128] Furthermore, the controller 192 can also control the shaver 001 to perform the following functions:
[0129] When the current of the drive motor 131 is less than the first preset value but greater than the second preset value, the indicator light 171 flashes.
[0130] When the current of the drive motor 131 is less than the second preset value, the indicator light 171 stays on.
[0131] The second preset value is less than the first preset value. The range of the second preset value can be from 0.1A to 0.4A, and a further range can be from 0.15A to 0.3A, specifically 0.1A, 0.15A, 0.3A, 0.4A, etc.
[0132] Examples are given below:
[0133] After the shaver 001 is started, and when the shaver head 200 is not in contact with the user's skin, the load on the drive motor 131 is at its minimum. At this time, the current of the drive motor 131 is less than the second preset value, and the indicator light 171 remains lit in white light.
[0134] When the blade 200 contacts the user's skin and the user applies moderate pressure, the load on the drive motor 131 increases, causing the current of the drive motor 131 to be greater than the second preset value and less than the first preset value, and the indicator light 171 flashes in white light.
[0135] When the user applies greater force, the load on the drive motor 131 increases further, causing the current of the drive motor 131 to exceed the first preset value, and the indicator light 171 flashes red light.
[0136] The working principle of the shaver 001 in some embodiments of this utility model will be briefly explained below with reference to Figures 5 to 10.
[0137] After the shaver 001 is started, and before the shaver head 200 contacts the user's skin, the transmission gear 141 is separated from the fixed bracket 120 under the action of the elastic member 144, and no friction is generated between the transmission gear 141 and the fixed bracket 120.
[0138] If the shaver 001 does not have an elastic member 144, even if the transmission gear 141 is in contact with the fixed bracket 120, the friction between the transmission gear 141 and the fixed bracket 120 is small and can be ignored because it does not compress the fixed bracket 120.
[0139] At this time, the current of the drive motor 131 is less than the second preset value, and the indicator light 171 outputs light of the first color and remains constantly lit.
[0140] When the blade 200 contacts the user's skin and the user applies moderate pressure, the blade 200 compresses the drive shaft 142, causing the drive gear 141 to float with the drive shaft 142 until it contacts the fixed bracket 120, applying a certain pressure to the fixed bracket 120. This generates friction between the drive gear 141 and the fixed bracket 120. Consequently, the load on the drive motor 131 increases, causing the current of the drive motor 131 to exceed the second preset value but be less than the first preset value. The indicator light 171 continues to output the first color light and begins to flash.
[0141] When the user applies greater pressure, the transmission gear 141 exerts greater pressure on the fixed bracket 120, increasing the friction between the transmission gear 141 and the fixed bracket 120. This leads to a further increase in the load on the drive motor 131, causing the current in the drive motor 131 to exceed the first preset value. The indicator light 171 then changes its output light from the first color to the second color and may flash simultaneously. Upon seeing the second color light, the user understands that the shaving pressure is too high and poses a risk of skin damage, requiring them to reduce the pressure.
[0142] Based on the foregoing description, those skilled in the art will understand that this invention, by providing a reflective member 180 inside the housing 110 to reflect the light emitted by the indicator light 171 to the light-transmitting portion of the housing 110, allows the indicator light 171 to be positioned less tightly against the housing 110, providing more installation options. Furthermore, by providing a light pattern forming structure on the light-transmitting portion of the housing 110 and / or the reflective member 180, the light emitted by the indicator light 171 can form a light pattern on the housing 110, optimizing the display experience of the indicator light 171 of the shaver 001.
[0143] Furthermore, this invention also enables the drive shaft 142 and drive gear 141 to float axially relative to the fixed bracket 120, achieving contact and separation with the fixed bracket 120. This allows for sliding contact with the fixed bracket 120 when the shaver head 200 is compressed, increasing the load on the drive motor 131. The controller 192 detects the load on the drive motor 131, and the indicator light 171 changes accordingly, allowing the user to understand the shaving intensity of the shaver 001 based on the different light information, thus avoiding excessive shaving force and skin damage. In this way, the shaver 001 of this invention does not require additional sensors to detect and indicate whether the shaving intensity is appropriate, avoiding increased costs.
[0144] In other words, in this invention, the pressure change of the transmission gear 141 relative to the fixed bracket 120 can convert the shaving pressure when the user uses the shaver 001 into the current change of the drive motor 131, so that the combination of the transmission shaft 142 and the fixed bracket 120 is equivalent to a pressure sensor.
[0145] Finally, it should be noted that in the description of this utility model, "a certain part is translucent" means that the material of that certain part is a translucent material, which can be plastic, glass, etc.
