Description

Technical Field

[0001] This application relates to the field of shaving, and particularly to an adjustable exposure razor head. Background Art

[0002] With the continuous economic development and social progress, a rich variety of consumer goods are provided, creating good conditions for improving people's living standards and pursuing personalized lives, thus accelerating the demand for consumer goods. Manual razors are one of many consumer goods.

[0003] As is well known, a razor head in a manual razor generally includes a head frame, one or more blades, a guard installed on the front side of the head frame, and a lubricating strip installed on the rear side of the head frame; one or more blades are installed at a position of the head frame between the guard and the lubricating strip. The guard and the lubricating strip can help establish the exposure of the blade. The way to establish the exposure is to draw a plane that is tangent to both the guard and the lubricating strip, and then measure the vertical distance or height between the cutting edge of the blade and this plane.

[0004] Among them, in the razor head, there can be positive exposure, negative exposure, and zero exposure (also known as neutral exposure); because blades with some negative exposure can better protect the skin while optimally cutting hair, and blades with some positive exposure can better release trapped hair. Blades with zero exposure make the skin just graze the surface.

[0005] However, since the exposure of the blades in the existing manual razor heads is fixed and non-adjustable, the existing manual razor heads cannot flexibly adjust the exposure according to actual needs to ensure a better shaving effect.

[0006] Therefore, there is an urgent need for an adjustable exposure razor head that can adjust the exposure of the blades to ensure the shaving effect to overcome the above defects.

[0007] Application Content

[0008] The purpose of this application is to provide an adjustable exposure razor head that can adjust the exposure of the blades to ensure the shaving effect.

[0009] To achieve the above object, the present application provides an exposure-adjustable razor head, including a head frame, a blade, a clip, an exposure adjustment member spaced from the blade in the front-rear direction of the head frame, and an operating member interlocked with the exposure adjustment member. The head frame is provided with a receiving space for receiving the blade, and a plurality of elastic legs extending from the left and right side walls of the head frame and arranged at intervals in the front-rear direction of the head frame are located in the receiving space; the blade is located in the receiving space, and the left and right ends of the blade are respectively placed on the elastic legs at the same end; the clips are respectively arranged on the left and right sides of the head frame and assembled to the head frame, and the clips also span and press against the blade in the front-rear direction of the blade frame; the exposure adjustment member is located in the receiving space and extends in the left-right direction of the head frame, and the left and right ends of the exposure adjustment member are respectively supported by one or more of the remaining elastic legs at the same end, and the clips also span and press against the exposure adjustment member in the front-rear direction of the head frame, so that the exposure adjustment member slides up and down at the head frame by means of the elastic deformation of the elastic legs; the operating member is movably mounted on the head frame, and the operating member can interlock the exposure adjustment member to make a sliding adjustment in the up-down direction on the head frame.

[0010] Preferably, the operating members are respectively located on the left and right sides of the head frame; on the same side, the clip also spans and presses against the operating member, and the exposure adjustment member is interlocked to make a sliding adjustment in the up-down direction by pushing and pulling the operating member to slide left and right along the head frame.

[0011] Preferably, the operating member is exposed outside the head frame, and one of the operating member and the exposure adjustment member has a first inclined surface inclined in the up-down direction of the head frame, and the other of the operating member and the exposure adjustment member has a second inclined surface or a convex structure that is in abutting cooperation with the first inclined surface; the operating member interlocks the exposure adjustment member to make a sliding adjustment in the up-down direction by means of the abutting cooperation between the second inclined surface or the convex structure and the first inclined surface during the left-right sliding process.

[0012] Preferably, the operating member is provided with a positioning structure, and the head frame, the clip or the exposure adjustment member is provided with a mating structure that cooperates with the positioning structure; when the operating member interlocks the exposure adjustment member to slide to a preset position, the positioning structure is in positioning cooperation with the mating structure.

[0013] Preferably, one of the positioning structure and the mating structure is a positioning convex and the other is a positioning concave.

[0014] Preferably, the left and right side walls of the cutter head frame are each provided with a guiding chute and a limiting groove that communicate with each other. The guiding chute is arranged in a penetrating manner along the left-right direction of the cutter head frame and communicates with the accommodating space. The limiting groove is separated from the accommodating space and there is a limiting structure between the two. The operating member is assembled in the guiding chute and the limiting groove at the same time.

[0015] Preferably, a pair of assembly legs that are spaced apart from each other and protrude downward are provided at each of the left end and / or the right end of the exposure amount adjusting member. The assembly legs are assembled within the cutter head frame.

[0016] Preferably, a plurality of ribs that are spaced apart from each other and transverse to the exposure amount adjusting member in the front-rear direction of the cutter head frame are provided on the top surface of the exposure amount adjusting member. The ribs are arched with the middle protruding relative to the two sides.

[0017] Preferably, the width of the rib is large in the middle and small at both sides, so that the width of the guiding channel enclosed between two adjacent ribs is small in the middle and large at both sides. A through hole is vertically penetrated through the part of the exposure amount adjusting member located between two adjacent ribs, and the through hole communicates with the guiding channel.

[0018] Preferably, the blade includes a first blade and a second blade that are spaced apart from each other. The exposure amount adjusting member is located between the first blade and the second blade.

[0019] Compared with the prior art, since the exposure amount adjustable cutter head of the present application further includes an exposure amount adjusting member that is separated from the blade in the front-rear direction of the cutter head frame and an operating member that is linked to the exposure amount adjusting member, the exposure amount adjusting member is located in the accommodating space and extends in the left-right direction of the cutter head frame. Each of the left and right ends of the exposure amount adjusting member is supported by one or more of the remaining spring legs at the same end. The clip also spans and presses against the exposure amount adjusting member in the front-rear direction of the cutter head frame, so that the exposure amount adjusting member slides up and down at the cutter head frame by means of the elastic deformation of the spring legs. The operating member is movably installed on the cutter head frame, and the operating member can link the exposure amount adjusting member to make a sliding adjustment in the up-down direction on the cutter head frame. Therefore, when adjusting the exposure amount of the blade, at this time, the operator operates the operating member, and the operated operating member links the exposure amount adjusting member to make a sliding adjustment in the up-down direction on the cutter head frame, so that the blade can be flexibly in different exposure amount positions, thereby obtaining a better shaving effect. For example, for naturally curly hair, in order to prevent inflammation caused by the root position of the cut hair being too deep and the curly hair piercing into the hair follicle during the regrowth process of the hair root, at this time, it is necessary to make the blade in a negative exposure amount.

[0031] In order to elaborate on the technical content and structural features of the present application in detail, the following further explanations are made in combination with the implementation manners and with reference to the drawings.

[0032] Please refer to Figures 1 to 5, the exposure-adjustable razor head 100 of the present application includes a head frame 10, a blade 20, a clip 30, an exposure adjustment member 40 spaced from the blade 20 in the front-rear direction of the head frame 10 (i.e., the direction indicated by arrow A and the opposite direction), an operating member 50 interlocked with the exposure adjustment member 40, a protective member 60 installed on the front side of the head frame 10, and a lubricating strip 70 installed on the rear side of the head frame 10. The head frame 10 is provided with a receiving space 11 for receiving the blade 20. On the left and right side walls 10a (10b) of the head frame 10, a plurality of resilient legs 12 are respectively extended and arranged at intervals in the front-rear direction of the head frame 10 within the receiving space 11. For example Figure 2 and Figure 5 as shown, the number of resilient legs 12 at the same end (i.e., the left end or the right end) is five. Of course, according to actual needs, the number of resilient legs 12 at the same end can also be three, four or six, etc., and thus it is not limited thereto. The blade 20 is located within the receiving space 11, and the left and right ends of the blade 20 are respectively placed on the resilient legs 12 at the same end, so that the blade 20 can make an adaptive up-and-down sliding adjustment by means of the up-and-down elastic deformation range of the resilient legs 12; preferably, the blade 20 includes a first blade 21 and a second blade 22 spaced from each other. Of course, according to actual needs, the number of blades 20 can also be other numbers, and thus it is not limited thereto. The clips 30 are respectively arranged on the left and right sides of the head frame 10 and assembled to the head frame 10, so that the clips 30 are assembled with the head frame 10; the clips 30 also straddle and press against the blade 20 in the front-rear direction of the blade frame 10 to prevent the blade 20 from sliding out of the blade frame 10 upward. The exposure adjustment member 40 is located within the receiving space 11 and extends in the left-right direction of the head frame 10 (i.e., the direction indicated by arrow B and the opposite direction), so that the left and right ends of the exposure adjustment member 40 are respectively supported by one or more of the remaining resilient legs 12 at the same end. For example, by Figure 2 and Figure 5Supported by the three kicking legs 12 shown. Of course, it can be supported by one, two or four kicking legs 12 according to actual needs, so this is not limited thereto. Preferably, when the blade 20 includes a first blade 21 and a second blade 22, the exposure adjustment member 40 is located between the first blade 21 and the second blade 22 at this time to ensure that there is a flushing gap between the three, but this is not limited thereto. The clip 30 also straddles and presses against the exposure adjustment member 40 in the front-back direction of the cutter head frame 10, so that the exposure adjustment member 40 can make reliable up-and-down sliding at the cutter head frame 10 by the elastic deformation of the kicking legs 12 under the action of the clip 30, preventing the exposure adjustment member 40 from accidentally slipping out of the cutter head frame 10. The operating member 50 is movably installed on the cutter head frame 10, and the operating member 50 can drive the exposure adjustment member 40 to make a sliding adjustment in the up-and-down direction on the cutter head frame 10. The protective member 60 and the lubricating strip 70 each extend along the left-right direction of the cutter head frame 10 and are located outside the accommodation space 11 in the front-back direction of the cutter head frame 10, so that the blade 20 and the exposure adjustment member 40 are located between the protective member 60 and the lubricating strip 70 in the front-back direction of the cutter head frame 10. It can be understood that, according to actual needs, the protective member 60 and / or the lubricating strip 70 can be removed, that is, the protective member 60 is not installed on the front side of the cutter head frame 10 and / or the lubricating strip 70 is not installed on the rear side of the cutter head frame 10, so this is not limited thereto. More specifically, as follows:

[0033] As Figures 1 to 4 shown, the operating members 50 are respectively located on the left and right sides of the cutter head frame 10 to facilitate the operator to adjust the exposure adjustment member 40 by means of the operating members 50 on the left and right sides of the cutter head frame 10. Among them, in the same side (that is, the left or right side of the cutter head frame 10), the clip 30 also straddles and presses against the operating member 50 to prevent the operating member 50 from sliding out of the cutter head frame 10 upward. Therefore, by pulling and pushing the operating member 50 to slide left and right along the cutter head frame 10, the exposure adjustment member 40 is driven to make a sliding adjustment in the up-and-down direction (that is, the direction indicated by the arrow C and the opposite direction). For example, in Figure 4 when pulling the left operating member 50 to slide left and the right operating member 50 to slide right (the direction is shown by the arrows beside them), and under the elastic action of the kicking legs 12, the exposure adjustment member 40 slides upward and returns to the initial position, and the state of the initial position is shown in Figure 10b shown; and the state of the exposure adjustment member 40 that slides to the preset position shown in Figure 4 is shown in Figure 10a shown. Specifically, in Figure 2 , Figure 4 , Figure 6 , Figure 8 and Figure 9In the figure, the operating member 50 is exposed from the cutter head frame 10, the exposure amount adjusting member 40 has a first inclined surface 41 inclined in the up and down directions of the cutter head frame 10, and the operating member 50 has a second inclined surface 52 which is pushed and matched with the first inclined surface 41; therefore, during the left and right sliding process of the operating member 50, the operating member 50 drives the exposure amount adjusting member 40 to make an up and down sliding adjustment with the help of the second inclined surface 52 and the push and match of the first inclined surface 41, so as to simplify the linkage structure between the operating member 50 and the exposure amount adjusting member 40, and make the linkage assembly relationship between the two and the processing of the linkage structure easier; of course, according to actual needs, the operating member 50 may also have a protruding structure which is pushed and matched with the first inclined surface 41, such as but not limited to a convex point, etc., which can also achieve the purpose of driving the exposure amount adjusting member 40 to make an up and down sliding adjustment with the help of the protruding structure and the push and match of the first inclined surface 41 during the left and right sliding process of the operating member 50. To ensure the adjustment effect, the operating member 50 is provided with a positioning structure 52a, preferably, the positioning structure 52a is located on the second inclined surface 52; the exposure amount adjustment member 40 is provided with a matching structure 42 matched with the positioning structure 52a, preferably, the matching structure 42 is located on the first inclined surface 41, so that when the operating member 50 links the exposure amount adjustment member 40 to slide to Figure 4 When the preset position is shown, the positioning structure 52a is positioned and matched with the matching structure 42, effectively preventing the operating member 50 from passively returning to the initial position under the action of the external force being lost and the elastic leg 12 driving the exposure adjustment member 40 to slide upward and reset; for example, the positioning structure 52a is a positioning protrusion, such as but not limited to Figure 4 and Figure 9 The spherical protrusions shown are corresponding to the positioning structures 42 being positioning recesses, such as but not limited to spherical recesses. In addition, to further ensure the adjustment effect, the operating member 50 is also provided with a positioning structure 52b at a position away from the second inclined surface 52. Correspondingly, the cutter head frame 10 is also provided with a positioning structure 12. When the exposure amount adjustment member 40 slides to Figure 4 When the preset position is shown, the positioning structure 52b on the operating member 50 is also positioned and matched with the matching structure 12 on the cutter head frame 10; for example, the positioning structure 52b is a square block and the matching structure 12 is a square groove. It is understandable that according to actual needs, the first inclined surface 41 can be provided by the operating member 50, and correspondingly, the second inclined surface 52 or the protruding structure can be provided by the exposure amount adjustment member 40, so it is not limited to this; in addition, although Figure 6The first inclined surface 41 shown is formed by the top surfaces 41 at the left and right ends of the exposure amount adjusting member 40, and its position can also be other, so it is not limited to this; in addition, according to actual needs, the mating structure 42 can also be provided by the clip 30 or the cutter head frame 10, so it is not limited to this. It should be noted that due to the positioning structure 52a (52b), and the operating member 50 is pressed by the clip 30, when the positioning structure 52a (52b) is not positioned with the corresponding mating structure 42 (12), the positioning structure 52a (52b) at this time will push the clip 30 to lift upward to ensure the smooth sliding of the operating member 50 on the cutter head frame 10; similarly, when the positioning structure 52a (52b) is positioned with the corresponding mating structure 42 (12), the clip 30 descends at this time.

[0034] As Figure 2 shown, the left side wall 10a and the right side wall 10b of the cutter head frame 10 are each provided with a guide chute 14 and a limiting groove 15 that communicate with each other. The guide chute 14 is arranged through in the left-right direction of the cutter head frame 10 and communicates with the accommodation space 11, and the limiting groove 15 is separated from the accommodation space 11 and there is a limiting structure 16 between the two. The operating member 50 is assembled in the guide chute 14 and the limiting groove 15 at the same time, so as to block the operating member 50 when the operating member 50 drives the exposure amount adjusting member 40 to slide to Figure 4 the preset position shown to prevent the operating member 50 from sliding excessively into the cutter head frame 10. Specifically, the limiting groove 15 is located directly above the guide chute 14, and the guide chute 14 bisects the limiting groove 15; in addition, the mating structure 12 is located in the guide chute 14.

[0035] As Figures 6 to 8 shown, a pair of assembly legs 43 that are spaced apart from each other and protrude downward are provided at the left and right ends of the exposure amount adjusting member 40. Preferably, the assembly legs 43 at the left end of the exposure amount adjusting member 40 also protrude leftward, and the assembly legs 43 at the right end of the exposure amount adjusting member 40 also protrude rightward. The assembly legs 43 are assembled in the cutter head frame 10 to ensure the reliability of the assembly between the exposure amount adjusting member 40 and the cutter head frame 10. Specifically, a plurality of ribs 45 that are spaced apart from each other and are transverse to the exposure amount adjusting member 40 in the front-rear direction of the cutter head frame 10 are provided on the top surface 44 of the exposure amount adjusting member 40. The ribs 45 are arched with the middle protruding relative to the two sides. The state is shown in Figure 7As shown, the exposure adjustment member 40 is better fitted to the skin during shaving. More specifically, the width of the rib 45 is larger in the middle and smaller at both sides, so that the width of the guiding channel 46 enclosed between two adjacent ribs 45 is smaller in the middle and larger at both sides, that is, the front and rear ends of the guiding channel 46 are wide and the middle is narrow, so as to facilitate the collection of the hair passing over the first blade 21 at the front end of the guiding channel 46 and the release at the rear end, thus facilitating the second blade 22 to continue shaving the hair passing through the guiding channel 46. In addition, a through hole 47 is vertically provided through the part of the exposure adjustment member 40 located between two adjacent ribs 45, and the through hole 47 is communicated with the guiding channel 46, so as to facilitate the discharge of shaving debris and improve the rinsing ability.

[0036] It should be noted that the exposure adjustment member 40 does not have a cutting function. Its function is to provide control points for the skin and establish a shaving plane together with the protective member 60 and the lubricating strip 70 respectively; for example, in Figure 10a , since the exposure adjustment member 40 is linked by the operating member 50 and slides to the Figure 4 predetermined position as shown, at this time, the exposure adjustment member 40 and the protective member 60 establish a shaving plane P1, and the exposure adjustment member 40 and the lubricating strip 70 establish a shaving plane P2. Correspondingly, the exposure of the first blade 21 relative to the shaving plane P1 is D1, and the exposure of the second blade 22 relative to the shaving plane P2 is D2; for example, in Figure 10b , since the exposure adjustment member 40 returns upward to the initial position, at this time, the exposure adjustment member 40 and the protective member 60 establish a shaving plane P1`, and the exposure adjustment member 40 and the lubricating strip 70 establish a shaving plane P2`. Correspondingly, the exposure of the first blade 21 relative to the shaving plane P1` is D1`, and the exposure of the second blade 22 relative to the shaving plane P2` is D2`; from Figure 10a and Figure 10b it can be obtained by comparison that the exposure of the first blade 21 and the second blade 21 when the exposure adjustment member 40 slides downward to the preset position is less than the exposure when the exposure adjustment member 40 slides upward to the initial position. In addition, the exposure adjustment member 40 can be a metal part or a non-metal part, so it is not limited thereto.

[0037] Combined with the attached drawings, the adjustment process of the exposure adjustable razor head 100 of the present application will be described: as Figure 4 shown, when the exposure adjustment member 40 in the preset position is to be adjusted to the initial position as Figure 10b shown, at this time, the operator pulls out the left operating member 50 in Figure 4 , and pulls out the right operating member 50 in Figure 4 to the right. With the cooperation of the second inclined surface 52 and the first inclined surface 41, and under the action of the resilient leg 12 resetting upward, the operating member 50 links the exposure adjustment member 40 to slide upward to as Figure 10bThe initial position shown; when it is necessary to Figure 10b slip and adjust the exposure adjustment member 40 in the initial position shown to Figure 10a the preset position shown, at this time the operator pushes the operating member 50 on the left into the cutter head frame 10, and pushes the operating member 50 on the right into the cutter head frame 10. With the cooperation of the second inclined surface 52 and the first inclined surface 41, the operating member 40 drives the exposure adjustment member 40 to slip downward against the elastic force of the spring leg 12 until the positioning structure 52a is positioned with the matching structure 42, and the positioning structure 52b is positioned with the matching structure 12. The state is shown in Figure 10a shown.

[0038] Compared with the prior art, since the exposure-adjustable cutter head 100 of the present application further includes an exposure adjustment member 40 spaced from the blade 20 in the front-rear direction of the cutter head frame 10 and an operating member 50 linked to the exposure adjustment member 40, the exposure adjustment member 40 is located in the accommodation space 11 and extends in the left-right direction of the cutter head frame 10. The left and right ends of the exposure adjustment member 40 are each supported by one or more of the remaining spring legs 12 at the same end. The clip 30 also spans and presses against the exposure adjustment member 40 in the front-rear direction of the cutter head frame 10, so that the exposure adjustment member 40 slides up and down at the cutter head frame 10 by means of the elastic deformation of the spring legs 12; the operating member 50 is movably mounted on the cutter head frame 10, and the operating member 50 can drive the exposure adjustment member 40 to make a sliding adjustment in the up-down direction on the cutter head frame 10; therefore, when it is necessary to adjust the exposure of the blade 20, at this time the operator operates the operating member 50, and the operated operating member 50 drives the exposure adjustment member 40 to make a sliding adjustment in the up-down direction on the cutter head frame 10, so that the blade 20 can be flexibly positioned at different exposure positions, thereby obtaining a better shaving effect; for example, for naturally curly hair, in order to prevent the root of the hair from being cut too deeply and causing inflammation due to curling and piercing into the hair follicle during the regrowth process of the hair root, at this time it is necessary to make the blade 20 in a negative exposure.

[0039] It should be noted that the clip 30 can be a metal sheet or a non-metal sheet. Although Figures 1 to 3 the clips 30 on the left and right sides of the cutter head frame 10 shown are independent of each other, of course, the clips 30 on the left and right sides of the head frame 10 can be integrated according to actual needs, so this is not limited thereto. In addition, the direction indicated by the arrow A in the attached drawing is the front-to-back direction of the cutter head frame 10, the direction indicated by the arrow B is the left-to-right direction of the cutter head frame 10, and the direction indicated by the arrow C is the up-to-down direction of the cutter head frame 10.

[0040] The above-disclosed are only the preferred examples of the present application. Of course, the scope of rights of the present application cannot be limited thereby. Therefore, equivalent changes made in accordance with the claims of the present application still fall within the scope covered by the present application.
