As is well known, a shaving head in a manual shaver generally includes a head frame, one or more blades, a guard mounted on a front side of the head frame, and a lubricating strip mounted on a rear side of the head frame; one or more blades are mounted to the bit frame at a location between the guard and the lubricating strip. The guard and lubricating strip can help establish blade exposure by drawing a plane that is tangential to both the guard and lubricating strip and measuring the perpendicular distance or height of the blade edge from the plane.

Wherein in the shaving head, there may be positive, negative and zero exposure (also called neutral exposure); as a blade with some negative exposure may better protect the skin while optimally cutting hair, and a blade with some positive exposure may better release trapped hair. There is zero exposure of the blade to have the skin just rubbed across the surface.

However, since the exposure of the blades of the shaving head in the existing manual shaver is fixed and not adjustable, the existing manual shaver head cannot flexibly adjust the exposure according to actual needs to ensure better shaving effect.

Accordingly, there is a need for an exposure adjustable shaving head that allows the exposure of the blades to be adjusted to ensure a shaving effect that overcomes the aforementioned drawbacks.

Detailed Description

In order to explain technical contents and structural features of the present application in detail, the following description is further made with reference to the embodiments and the accompanying drawings.

Referring to fig. 1 to 5, the exposure adjustable razor head 100 of the present invention includes a head frame 10, a blade 20, a clip 30, an exposure adjustment member 40 spaced apart from the blade 20 in a front-rear direction of the head frame 10 (i.e., a direction indicated by an arrow a and an opposite direction), an operating member 50 linked to the exposure adjustment member 40, a guard member 60 mounted on a front side of the head frame 10, and a lubricating strip 70 mounted on a rear side of the head frame 10. The cutter head frame 10 is provided with an accommodating space 11 for accommodating the blade 20, and a plurality of spring legs 12 which are located in the accommodating space 11 and are arranged in the front-rear direction of the cutter head frame 10 are respectively extended from the left and right side walls 10a (10 b) of the cutter head frame 10, for example, the number of the spring legs 12 at the same end (i.e., the left end or the right end) shown in fig. 2 and 5 is five, and of course, according to actual needs, the number of the spring legs 12 at the same end may be three, four or six, and is not limited thereto. The blade 20 is positioned in the accommodating space 11, and the left end and the right end of the blade 20 are respectively placed on the elastic legs 12 at the same end, so that the blade 20 can be adjusted to slide up and down adaptively by virtue of the range of the elastic deformation of the elastic legs 12; preferably, the blade 20 includes a first blade 21 and a second blade 22 spaced apart from each other, although the number of blades 20 may be other according to actual needs, and is not limited thereto. The clamping pieces 30 are respectively arranged at the left and right sides of the bit frame 10 and assembled to the bit frame 10, so that the clamping pieces 30 are assembled with the bit frame 10; the clips 30 also straddle and press against the blades 20 in the fore-aft direction of the blade frame 10 to prevent the blades 20 from sliding up out of the blade frame 10. The exposure adjustment member 40 is located in the accommodating space 11 and extends along the left and right directions (i.e. the direction indicated by the arrow B and the opposite direction) of the cutter head frame 10, so that the left and right ends of the exposure adjustment member 40 are supported by the remaining one or more of the spring legs 12 at the same end, such as the three spring legs 12 shown in fig. 2 and 5, but may be supported by one, two or four spring legs 12 according to actual needs, and is not limited thereto; preferably, when the blade 20 includes the first blade 21 and the second blade 22, the exposure adjustment member 40 is located between the first blade 21 and the second blade 22 to ensure that a rinsing gap is left between the three, but not limited thereto. The clip 30 also crosses and presses the exposure adjustment member 40 in the front-rear direction of the bit frame 10, so that the exposure adjustment member 40 can reliably slide up and down on the bit frame 10 by the elastic deformation of the elastic legs 12 under the action of the clip 30, and the exposure adjustment member 40 can be prevented from accidentally sliding out of the bit frame 10. The operating element 50 is movably attached to the head frame 10, and the operating element 50 is slidably moved in the vertical direction on the head frame 10 in association with the exposure amount adjusting member 40. The protector 60 and the lubricating strip 70 each extend in the left-right direction of the head frame 10 and are located outside the accommodating space 11 in the front-rear direction of the head frame 10, with the blade 20 and the exposure amount adjusting member 40 being located between the protector 60 and the lubricating strip 70 in the front-rear direction of the head frame 10. It will be appreciated that the guard 60 and/or the lubricating strip 70 may be removed according to actual needs, i.e., the guard 60 is not mounted on the front side of the head frame 10 and/or the lubricating strip 70 is not mounted on the rear side of the head frame 10, and thus not limited thereto. More specifically, the following:

as shown in fig. 1 to 4, the operating parts 50 are respectively located at the left and right sides of the head frame 10, so that an operator can adjust the exposure amount adjusting member 40 by means of the operating parts 50 at the left and right sides of the head frame 10; wherein in the same side (i.e. left or right side of the bit frame 10) the clips 30 also span and press against the operating member 50 to prevent the operating member 50 from sliding up out of the bit frame 10; therefore, the operation member 50 is pulled and pushed to slide along the left and right of the head frame 10, so as to move the exposure adjustment member 40 to slide and adjust in the up and down direction (i.e., the direction indicated by the arrow C and the opposite direction); for example, in fig. 4, during the process of pulling the left operating member 50 to slide to the left and the right operating member 50 to slide to the right (the directions are indicated by arrows beside them), the exposure adjusting member 40 slides upwards to return to the initial position under the elastic action of the elastic leg 12, and the initial position is shown in fig. 10 b; and the exposure amount adjustment member 40 slid to the preset position shown in fig. 4 is shown in fig. 10 a. Specifically, in fig. 2, 4, 6, 8 and 9, the operating element 50 is exposed to the head frame 10, the exposure adjustment member 40 has a first inclined surface 41 inclined in the up-down direction of the head frame 10, and the operating element 50 has a second inclined surface 52 in pushing fit with the first inclined surface 41; therefore, in the process of sliding the operating element 50 left and right, the operating element 50 is linked with the exposure adjusting member 40 to perform sliding adjustment up and down by the pushing cooperation of the second inclined surface 52 and the first inclined surface 41, so as to simplify the linkage structure between the operating element 50 and the exposure adjusting member 40, and make the linkage assembly relationship between the operating element 50 and the exposure adjusting member 40 and the processing of the linkage structure easier; of course, according to actual requirements, the operating element 50 may also have a protrusion structure that is in pushing fit with the first inclined surface 41, such as but not limited to the convex point, and the like, and the purpose of sliding adjustment of the operating element 50 up and down by the pushing fit of the protrusion structure and the first inclined surface 41 in the process of sliding left and right can be achieved. In order to ensure the adjustment effect, the operating element 50 is provided with a positioning structure 52a, preferably, the positioning structure 52a is located on the second inclined surface 52; the exposure 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 operation member 50 is linked with the exposure adjustment member 40 and slides to the preset position shown in fig. 4, the positioning structure 52a is matched with the matching structure 42 in a positioning manner, and the operation member 50 is effectively prevented from passively returning to the initial position under the action of losing external force and the action of the elastic leg 12 driving the exposure adjustment member 40 to slide upwards and return; for example, the positioning structure 52a is a positioning protrusion, such as but not limited to the spherical convex point shown in fig. 4 and 9, and correspondingly, the matching structure 42 is a positioning recess, such as but not limited to the spherical concave. 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 matching structure 12, and when the exposure adjustment member 40 slides to the preset position shown in fig. 4, the positioning structure 52b on the operating member 50 is also in positioning fit with the matching structure 12 on the cutter head frame 10; for example, the positioning structure 52b is a square block and the positioning structure 12 is a square groove. It can be understood that, according to actual needs, the first inclined surface 41 can be provided by the operating element 50, and correspondingly, the second inclined surface 52 or the protruding structure can be provided by the exposure adjusting member 40, so it is not limited thereto; in addition, although fig. 6 shows the first inclined surface 41 formed by the top surface 41 of the left and right ends of the exposure amount adjusting member 40, its position may be other, and thus is not limited thereto; in addition, the configuration 42 may be provided by the clip 30 or the bit frame 10 according to actual needs, and is not limited thereto. It should be noted that, because the positioning structure 52a (52 b) and the operating element 50 are pressed by the clip 30, when the positioning structure 52a (52 b) is not positioned with the corresponding mating structure 42 (12), the positioning structure 52a (52 b) will push the clip 30 to lift upward to ensure the smoothness of sliding movement of the operating element 50 on the head frame 10; similarly, when the positioning structure 52a (52 b) is positioned with the corresponding mating structure 42 (12), the clip 30 is lowered.

As shown in fig. 2, the left side wall 10a and the right side wall 10b of the cutter head frame 10 are respectively provided with a guide groove 14 and a stopper groove 15 which are communicated with each other. The guide chute 14 penetrates through the cutter head frame 10 in the left-right direction and is communicated with the accommodating space 11, the limiting groove 15 is separated from the accommodating space 11, a limiting structure 16 is arranged between the limiting groove 15 and the accommodating space 11, and the operating part 50 is assembled in the guide chute 14 and the limiting groove 15 at the same time, so that when the operating part 50 is linked with the exposure adjusting member 40 and slides to a preset position shown in fig. 4, the limiting structure 16 blocks the operating part 50, and the operating part 50 is prevented from sliding and transiting to the interior of the cutter head frame 10. Specifically, the limit groove 15 is located right above the guide sliding groove 14, and the guide sliding groove 14 bisects the limit groove 15; in addition, the mating structure 12 is located in the guide channel 14.

As shown in fig. 6 to 8, the left and right ends of the exposure amount adjustment member 40 are respectively provided with a pair of mounting legs 43 spaced apart from each other and protruding downward, and preferably, the mounting leg 43 of the left end of the exposure amount adjustment member 40 further protrudes leftward, the mounting leg 43 of the right end of the exposure amount adjustment member 40 further protrudes rightward, and the mounting legs 43 are mounted in the head frame 10 to ensure the reliability of the mounting between the exposure amount adjustment member 40 and the head frame 10. Specifically, the top surface 44 of the exposure adjustment member 40 is provided with a plurality of ribs 45 spaced apart from each other and extending transversely to the exposure adjustment member 40 in the front-rear direction of the head frame 10, the ribs 45 being arched with the center thereof being convex toward the opposite sides, as shown in fig. 7, so that the exposure adjustment member 40 is better fitted to the skin during shaving. More specifically, the ribs 45 have a width that is large in the middle and small in the two sides, so that the width of the guide channel 46 enclosed between two adjacent ribs 45 is small in the middle and large in the two sides, i.e., the front and rear ends of the guide channel 46 are wide and narrow in the middle, so that hairs passing over the first blade 21 are collected at the front end of the guide channel 46 and released at the rear end, thereby facilitating the second blade 22 to continue shaving hairs passing through the guide channel 46. In addition, the exposure adjustment member 40 has a through hole 47 penetrating from top to bottom at a position between two adjacent ribs 45, and the through hole 47 is communicated with the guide channel 46, so as to facilitate the removal of shaving debris and improve the rinsing capability.

It should be noted that the exposure adjustment member 40 does not have a cutting function, and its function is to provide a control point for the skin and establish a shaving plane together with the guard 60 and the lubricating strip 70, respectively; for example, in fig. 10a, since the exposure adjustment member 40 is moved by the operation element 50 to the preset position shown in fig. 4, the exposure adjustment member 40 and the protection element 60 establish a shaving plane P1 and the lubrication strip 70 establish a shaving plane P2, and accordingly, the exposure of the first blade 21 to the shaving plane P1 is D1 and the exposure of the second blade 22 to the shaving plane P2 is D2; for example, in fig. 10b, since the exposure adjustment member 40 returns to the initial position, the exposure adjustment member 40 and the guard 60 establish a shaving plane P1 'and a shaving plane P2' with the lubricating strip 70, respectively, the exposure of the first blade 21 with respect to the shaving plane P1 'is D1', and the exposure of the second blade 22 with respect to the shaving plane P2 'is D2'; as is apparent from a comparison of fig. 10a and 10b, the exposure amounts of the first and second blades 21 and 21 when the exposure amount adjustment member 40 slides down to the preset position are smaller than the exposure amount when the exposure amount adjustment member 40 slides up to the initial position. The exposure adjustment component 40 may be a metal component or a non-metal component, and is not limited thereto.

The adjustment process of the exposure adjustable razor head 100 of the present application will be described with reference to the accompanying drawings: as shown in fig. 4, when the exposure amount adjustment member 40 in the preset position is to be adjusted to the initial position shown in fig. 10b, at this time, the operator pulls out the operation piece 50 on the left side in fig. 4 to the left side, and pulls out the operation piece 50 on the right side in fig. 4 to the right side, and by the cooperation of the second inclined surface 52 and the first inclined surface 41, and the elastic leg 12 is reset upward, the operation piece 50 moves the exposure amount adjustment member 40 upward to the initial position shown in fig. 10 b; when the exposure adjustment member 40 in the initial position shown in fig. 10b is to be slidably adjusted to the preset position shown in fig. 10a, the operator pushes the left operating element 50 into the head frame 10 and pushes the right operating element 50 into the head frame 10, and the operating element 40 and the exposure adjustment member 40 are slidably moved downward against the elastic force of the elastic leg 12 by the cooperation of the second inclined surface 52 and the first inclined surface 41 until the positioning structure 52a is positioned with the positioning structure 42 and the positioning structure 52b is positioned with the positioning structure 12, as shown in fig. 10 a.

Compared with the prior art, because the exposure adjustable shaver head 100 of the present application further includes the exposure adjusting member 40 spaced apart from the blade 20 along the front-rear direction of the head frame 10 and the operating member 50 linked with the exposure adjusting member 40, the exposure adjusting member 40 is located in the accommodating space 11 and extends along the left-right direction of the head frame 10, the left and right ends of the exposure adjusting member 40 are respectively supported by the remaining one or more of the spring legs 12 at the same end, the clip 30 also crosses and presses the exposure adjusting member 40 along the front-rear direction of the head frame 10, so that the exposure adjusting member 40 slides up and down at the head frame 10 by virtue of the elastic deformation of the spring legs 12; the operating element 50 is movably mounted on the head frame 10, and the operating element 50 can be linked with the exposure amount adjusting member 40 to perform sliding adjustment in the vertical direction on the head frame 10; therefore, when the exposure of the blade 20 is to be adjusted, the operator operates the operating element 50, and the operated operating element 50 is used to link the exposure adjusting member 40 to perform vertical sliding adjustment on the head frame 10, so that the blade 20 can be flexibly positioned at different exposure positions, and a better shaving effect is obtained; for example, for naturally curly hair, it is desirable to expose the blade 20 negatively to prevent inflammation caused by the hair being cut too deeply and penetrating the follicle during regrowth of the hair root by curling.

It should be noted that the clamping pieces 30 may be metal pieces or non-metal pieces, although the clamping pieces 30 on the left and right sides of the head frame 10 shown in fig. 1 to 3 are independent from each other, of course, the clamping pieces 30 on the left and right sides of the head frame 10 may be connected into a whole according to actual needs, and therefore, the invention is not limited thereto. In addition, the direction indicated by the arrow a in the 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 top-to-bottom direction of the cutter head frame 10.

The above disclosure is only a preferred embodiment of the present application, and certainly does not limit the scope of the present application, which is therefore intended to cover all modifications, equivalents and alternatives falling within the scope of the present application as defined by the appended claims.
