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] Electric shavers are a common personal care appliance widely used in daily life. Traditional shavers typically consist of a body and a shaver head. The body houses a motor that drives the blades inside the shaver head via a transmission mechanism, thus achieving the shaving function. However, during use, users often find it difficult to accurately control the shaving pressure (the pressure the shaver exerts on the skin). Excessive shaving pressure can lead to problems such as nicks, redness, or pain, affecting the user experience and skin health. Summary of the Invention

[0003] One objective of this invention is to solve the problem that existing razors can easily damage the skin due to excessive shaving force during use.

[0004] To achieve the above objectives, this utility model provides a razor, including a body and a razor head, wherein the body includes:

[0005] Fixed bracket;

[0006] The drive motor is mounted on the fixed bracket;

[0007] A drive shaft is rotatably mounted on the fixed bracket and is axially floating relative to the fixed bracket; the drive shaft is driven by the drive motor and the cutter head respectively, so as to transmit the power of the drive motor to the cutter head;

[0008] The damping component is fixedly connected to the drive shaft and can contact or separate from the fixed bracket as the drive shaft floats, so as to slide into contact with the fixed bracket when the cutter head is squeezed, thereby generating frictional resistance and increasing the load on the drive motor.

[0009] Optionally, the maximum floating distance of the damping member relative to the fixed support is selected from any value between 0.1 mm and 5 mm.

[0010] Optionally, the maximum floating distance of the damping member relative to the fixed support is selected from any value between 0.2 mm and 1 mm.

[0011] Optionally, the body further includes a drive gear, which is coaxially and fixedly connected to the shaft of the drive motor; the damping member is a gear that meshes with the drive gear.

[0012] Optionally, the number of teeth of the drive gear is less than the number of teeth of the damping member.

[0013] Optionally, the fixed bracket is provided with a shaft hole, and the drive shaft is inserted into the shaft hole; the damping member is provided with a friction ring extending toward the shaft hole, so that the damping member slides in contact with the fixed bracket through the friction ring.

[0014] Optionally, the fixed bracket is provided with a groove communicating with the shaft hole, and a portion of the friction ring is embedded in the groove to reduce the distance between the side of the damping member away from the fixed bracket and the fixed bracket.

[0015] Optionally, the friction ring is interference-fitted with the drive shaft.

[0016] The fuselage also includes an elastic member for providing a force to the damping member away from the fixed support, so as to separate the damping member from the fixed support.

[0017] Optionally, the housing also includes indicator lights, the color of which and / or the flashing frequency varies with the load of the drive motor.

[0018] Based on the foregoing description, those skilled in the art will understand that in the aforementioned technical solution of this utility model, by making the drive shaft axially floatable relative to the fixed bracket and providing a damping component fixedly connected to the drive shaft, the damping component can contact or separate from the fixed bracket as the drive shaft floats, so that it slides against the fixed bracket when the shaver head is squeezed, thereby generating frictional resistance and increasing the load on the drive motor. In this way, due to the effect of the damping component, the increased load on the drive motor may reduce its rotational speed, thus reducing skin damage from the shaver. Simultaneously, the increased load on the drive motor will cause changes in the noise level of the shaver during operation, allowing the user to determine whether the shaving force is too strong based on the different noise levels.

[0019] Furthermore, by setting indicator lights whose color and / or flashing frequency change with the load of the drive motor, users can determine whether the shaver's shaving force is too strong based on the changes in the light, thus avoiding skin damage from the shaver.

[0020] Furthermore, by providing a force away from the fixed bracket through the elastic component, the damping component can be separated from the fixed bracket in time when the pressure of the shaver on the user's skin decreases, thus preventing the damping component from continuing to generate frictional force that hinders the operation of the drive motor.

[0051] Those skilled in the art should understand that the embodiments described below are merely some embodiments of the present invention, and not all embodiments of the present invention. These embodiments are intended to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of the present invention.

[0052] It should be noted that in the description of this utility model, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the corresponding device or element must have a specific orientation, or be constructed and operated in a specific orientation. 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. For example, unless otherwise specified, the terms "installation," "connection," "joining," and "fixing" can specifically refer to any feasible connection form such as bolt connection, screw connection, welding, insertion, riveting, fusion welding, or snap-fit.

[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 damping component 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] The drive motor 131 is mounted on the fixed bracket 120. The drive shaft 142 is rotatably mounted on the fixed bracket 120 and is axially floating relative to the fixed bracket 120. The drive shaft 142 is connected to both the drive motor 131 and the cutter head 200 to transmit power from the drive motor 131 to the cutter head. The damping member 141 is fixedly connected to the drive shaft 142 and can contact or separate from the fixed bracket 120 as the drive shaft 142 floats, allowing it to slide against the fixed bracket 120 when the cutter head 200 is compressed, thereby generating frictional resistance and increasing the load on the drive motor 131.

[0060] Those skilled in the art will understand that, due to the damping member 141, the rotational speed of the drive motor 131 may decrease after the load increases, thereby reducing the damage to the skin caused by the shaver 001. At the same time, the increased load on the drive motor 131 will cause changes in the noise of the shaver 001 during operation, thus allowing the user to determine whether the shaving force is too strong based on the different noise levels.

[0061] In other embodiments of this utility model, those skilled in the art may omit at least one of the following components as needed: housing 110, fixing bracket 120, drive motor 131, damping member 141, transmission shaft 142, top cover 150, sealing member 160, indicator light 171, reflector 180, battery 191, and controller 192. For example, sealing member 160, indicator light 171, and / or reflector 180 may be omitted.

[0062] The fuselage 100 in some embodiments of the present invention will now be described in further detail with reference to Figures 5 to 14.

[0063] 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 inside the outer shell 111 so as to hide the inner shell 112 through the outer shell 111.

[0064] 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.

[0065] 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, damping component 141, transmission shaft 142, indicator light 171, battery 191, and controller 192.

[0066] 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.

[0067] 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 shaft of the drive motor 131 is exposed.

[0068] As can be seen from Figures 5 to 10, 12 and 13, in some embodiments of this utility model, the body 100 further includes a drive gear 132, which is coaxially and fixedly connected to the shaft of the drive motor 131. Specifically, the drive gear 132 is coaxially and fixedly connected to the exposed shaft of the drive motor 131.

[0069] As can also be seen from Figures 5 to 10, 12 and 13, in some embodiments of the present invention, the damping member 141 is a gear that meshes with the drive gear 132, so that the power of the drive motor 131 can be transmitted to the transmission shaft 142 through the meshing of the damping member 141 with the drive gear 132.

[0070] As can be seen from Figures 12 and 13, in some embodiments of this utility model, the number of teeth of the drive gear 132 is less than the number of teeth of the damping member 141, so as to amplify the torque and make the torque obtained by the transmission shaft 142 greater than the torque output by the drive motor 131.

[0071] Furthermore, in other embodiments of this invention, those skilled in the art can also use any other feasible method to transmit the power of the drive motor 131 to the transmission shaft 142 as needed. For example, the drive gear 132 can be replaced with a pulley, the damping member 141 can be replaced with a pulley, or a pulley can be fixed on the transmission shaft 142, and the two pulleys can be driven together by a transmission belt (e.g., a belt, metal belt, etc.). In this way, the power of the drive motor 131 can be transmitted to the transmission shaft 142 through the two pulleys and the transmission belt.

[0072] As shown in Figures 5 to 10, 12 and 13, in some embodiments of this utility model, the top of the fixed 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 damping member 141 and can be set to be tapered.

[0073] As shown in Figures 6, 8, and 10, in some embodiments of this invention, a friction ring 1411 may be provided on the side of the damping member 141 facing the fixed bracket 120, so that the damping member 141 can slide 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.

[0074] Furthermore, the friction ring 1411 can be tapered and adapted to 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. This not only increases the friction between the damping member 141 and the fixed bracket 120, but also improves the wear resistance between them. Simultaneously, the fact that a portion of the friction ring 1411 is embedded in the groove 122 also reduces the distance between the side of the damping member 141 away from the fixed bracket 120 and the fixed bracket 120.

[0075] Furthermore, in some embodiments of this utility model, the friction ring 1411 is interference-fitted with the drive shaft 142 to increase the connection strength between the damping member 141 and the drive shaft 142.

[0076] 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 damping member 141 and is drively connected to the cutter head 200 to transmit the power generated by the drive motor 131 to the cutter head 200.

[0077] Referring to Figures 5 to 10, in some embodiments of this utility model, the transmission shaft 142 and the damping member 141 can be coaxially fixedly connected by an interference fit, or they can be coaxially fixedly connected by welding, bonding, keyway fit, etc.

[0078] Furthermore, the drive shaft 142 is buoyant relative to the fixed bracket 120 along its axial direction, so that the damping member 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.

[0079] As shown in Figure 6, in some embodiments of this utility model, the maximum floating distance H of the damping member 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.

[0080] Furthermore, the maximum floating distance H of the damping member 141 relative to the fixed support 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.

[0081] Those skilled in the art will understand that by setting the maximum floating distance H of the damping member 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 damping member 141 to changes in shaving force is ensured. This avoids situations where the damping member 141's action is not timely enough, preventing the user from understanding the shaving force and thus avoiding skin damage from the razor 001.

[0082] As shown in Figures 5 to 10, in some embodiments of the present invention, the fuselage 100 may further include an elastic member 144, which is used to provide a force to the damping member 141 away from the fixed bracket 120, so as to separate the damping member 141 from the fixed bracket 120.

[0083] 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.

[0084] In some embodiments of this utility model, the elastic member 144 can be a rubber ring, a compression spring, or any feasible structure.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] 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.

[0089] 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.

[0090] 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.

[0091] 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.

[0092] 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 first plug-in shaft 143 is arranged in the protective cavity 102.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] Furthermore, in order to ensure that light can pass through the housing 110, at least a portion of the housing 110 is light-transmitting (not marked in the figure), and 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 pass through the sealing member 160 and be reflected by the reflector 180 to the light-transmitting portion of the housing 110.

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] As shown in Figures 8 to 11 and 14, in some embodiments of this utility model, a light pattern forming structure 181 may also be provided on the reflective member 180 so that the light emitted by the indicator light 171 forms a light pattern on the housing 110.

[0116] In addition, in other embodiments of this utility model, those skilled in the art may, as needed, set 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.

[0117] 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.

[0118] Furthermore, the groove structure is a spiral groove or multiple annular grooves spaced apart.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] 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.

[0123] Furthermore, in some embodiments of this invention, the controller 192 is configured to keep the output speed of the drive motor 131 constant, while increasing 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. In this way, compared to making the speed of the drive motor 131 decrease as the load increases, the speed of the drive motor 131 is kept constant, thereby ensuring the shaving effect of the shaver 001.

[0124] Furthermore, the controller 192 can control the shaver 001 to perform the following functions:

[0125] 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.

[0126] 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.

[0127] 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.

[0128] The first color can be any feasible color such as white, green, or blue.

[0129] The second color can be any feasible color such as yellow or red.

[0130] Furthermore, the controller 192 can also control the shaver 001 to perform the following functions:

[0131] When the current of the drive motor 131 is greater than or equal to the first preset value, the indicator light 171 flashes.

[0132] Furthermore, the controller 192 can also control the shaver 001 to perform the following functions:

[0133] 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.

[0134] When the current of the drive motor 131 is less than the second preset value, the indicator light 171 stays on.

[0135] 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.

[0136] Examples are given below:

[0137] 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.

[0138] 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.

[0139] 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.

[0140] 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.

[0141] After the shaver 001 is started, and before the shaver head 200 contacts the user's skin, the damping member 141 is separated from the fixed bracket 120 under the action of the elastic member 144, and no friction is generated between the damping member 141 and the fixed bracket 120.

[0142] If the shaver 001 does not have an elastic member 144, even if the damping member 141 is in contact with the fixed bracket 120, the friction between the damping member 141 and the fixed bracket 120 is small and can be ignored because it does not compress the fixed bracket 120.

[0143] 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.

[0144] 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 damping member 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 damping member 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.

[0145] When the user applies greater pressure, the damping member 141 exerts greater pressure on the fixed bracket 120, increasing the friction between them. 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 color 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.

[0146] Based on the foregoing description, those skilled in the art will understand that this invention, by allowing the drive shaft 142 and damping member 141 to float axially relative to the fixed bracket 120, achieves 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 promptly 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 remind whether the shaving intensity is appropriate, avoiding increased costs.

[0147] In other words, in this invention, the pressure change of the damping member 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 drive shaft 142 and the fixed bracket 120 is equivalent to a pressure sensor.

[0148] 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.
