Description

Technical Field

[0001] The present invention relates to the technical field of shaving devices, and particularly to a shaving razor head and a shaving device. Background Art

[0002] Currently, in order to make a manual shaving razor more convenient to use, the detachable connection structure between the shaving razor head and the blade has always been the focus of technical improvement in this field. Currently, a rotary or pressing connection structure is usually adopted between the shaving razor head and the blade. Among them, when a user disassembles and installs the rotary connection structure, the user first rotates the old blade to remove the old blade from the base of the razor head, then rotates the base of the razor head to align the new blade with the installation slot, then inserts the new blade into the installation slot, and then rotates the new blade to fix it; when the user disassembles and installs the pressing connection structure, the user simultaneously presses the release buttons on both sides of the razor head to remove the old blade from the razor head, then aligns the new blade with the guiding card slot of the razor head, and then applies a vertical pressure to make them engage; in summary, the user needs to perform many and relatively complex steps and takes a long time (tens of seconds) to replace the blade in the above structure, making the operation of replacing the blade too troublesome and not convenient enough. This will cause the user to be more inclined to first use the old and less effective blade already installed on the razor head to shave when in urgent need of shaving, and then replace the blade afterwards, resulting in problems such as poor shaving effect and skin sensitivity. Summary of the Invention

Specific embodiments

[0028] The following will further describe in detail the specific embodiments of the present invention in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0029] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by terms such as "top", "bottom", "inner", "outer", "circumferential", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0030] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0031] Such as Figures 1 to 8As shown in the figure, the front side is defined as the direction in which the razor blade 1 faces the user, and the opposite side is the rear side. The upper and lower sides are distinguished by the upper and lower sides when the razor blade 1 is working normally in general. The left and right sides are distinguished by the left and right sides when the razor blade 1 faces the user. A razor blade 1 of this embodiment includes a knife holder 11, a knife box 12 and a separation component 13. The side of the knife holder 11 relative to the left-right direction is provided with a communicating mounting hole 111 and a protruding hole 112. The protruding hole 112 is located in front of the mounting hole 111 and penetrates forward to the front side of the knife holder 11. A connecting hole 113 penetrating to the mounting hole 111 is provided on the rear side or the top surface of the knife holder 11. The knife box 12 is installed in the mounting hole 111 and can move in the left-right direction. The knife box 12 passes through the protruding hole 112 and extends outside the knife holder 11. A clamping portion 121 is provided on the side of the knife box 12 relative to the connecting hole 113. The clamping portion 121 is clamped in the connecting hole 113. The separation component 13 is arranged in the connecting hole 113. The separation component 13 can move axially along the connecting hole 113 to push the clamping portion 121 away from the connecting hole 113.

[0032] In the above technical solution, the tool rest 11 is provided with a mounting hole 111 and an extending hole 112, both of which are provided on the left or right side of the tool rest 11. Among them, the extending hole 112 is located in front of the mounting hole 111 and penetrates through to the front side of the tool rest 11, so that the tool cartridge 12 can be inserted into the mounting hole 111 in the left-right direction and extend out of the outside of the tool rest 11 through the extending hole 112. Further, a connecting hole 113 penetrating through to the mounting hole 111 is also provided on the rear side or the top surface of the tool rest 11. A clamping portion 121 is provided on the side surface of the tool cartridge 12 corresponding to the connecting hole 113. The clamping portion 121 is clamped in the connecting hole 113, so that after the tool cartridge 12 is inserted into the mounting hole 111, it can be detachably fixed in the mounting hole 111 through the connecting hole 113. Further, the separating assembly 13 is arranged in the connecting hole 113 and can move axially along the connecting hole 113. When the user needs to remove the tool cartridge 12, the user can operate the separating assembly 13 to move towards the mounting hole 111 to abut against the clamping portion 121. The separating assembly 13 further moves towards the mounting hole 111 to push the clamping portion 121 away from the connecting hole 113, thereby separating the clamping portion 121 and the connecting hole 113. At this time, the user can push the tool cartridge 12 out of the mounting hole 111 in the left-right direction to remove the tool cartridge 12; specifically, the specific operation for the user to replace the tool cartridge 12 is as follows: operate the separating assembly 13 to release the connection between the old tool cartridge 12 and the connecting hole 113, push the old tool cartridge 12 out of the mounting hole 111, push the new tool cartridge 12 into the mounting hole 111 until the clamping portion 121 corresponds to the connecting hole 113, and connect the tool cartridge 12 to the connecting hole 113; In summary, when the user uses the razor blade 1 and the shaving device of this embodiment, the tool cartridge 12 can be replaced through simple steps and with less time consumption. The operation of replacing the blade is very simple, convenient and fast.

[0033] Among them, the tool cartridge 12 is installed with a blade, and the blade protrudes from the front side of the tool cartridge 12 to enable it to have a shaving function. Other auxiliary components such as a lubricating strip can also be provided on the tool cartridge 12.

[0034] Further, the mounting hole 111 and the extending hole 112 can penetrate through the tool rest 11, so that the user can insert and push out the tool cartridge 12 from both sides in the left-right direction.

[0035] In addition, the mounting hole 111 and the tool hole can be rectangular holes, and the width of the mounting hole 111 in the up-down direction is greater than the width of the tool hole in the up-down direction.

[0036] Further, the separation component 13 further includes an abutting member 131, an elastic element 132 and a limiting member 133. The abutting member 131 is disposed in the connection hole 113 and can move along the axial direction of the connection hole 113. The limiting member 133 is disposed on the abutting member 131 and protrudes from the outer sidewall of the abutting member 131. The tool holder 11 is provided with a limiting boss 114. Two sides of the limiting member 133 are respectively connected to the abutting member 131 and the limiting boss 114. Two ends of the elastic element 132 are respectively connected to the tool holder 11 and the abutting member 131. The elastic element 132 is used to apply a thrust force to the abutting member 131 away from the connection hole 113. When the abutting member 131 moves towards the mounting hole 111, the abutting member 131 can abut against the clamping portion 121 and push the clamping portion 121 away from the connection hole 113.

[0037] Among them, the abutting member 131 is used to directly contact the clamping portion 121 and push it away from the clamping portion 121. Specifically, the user only needs to apply an external force towards the mounting hole 111 to the abutting member 131. The abutting member 131 moves against the elastic force and abuts against the clamping portion 121, and then the clamping portion 121 can be pushed away from the connection hole 113. At this time, the tool magazine 12 loses its restraint and can be directly pushed out in the left - right direction. The elastic element 132 is used to keep the abutting member 131 in its initial position when no external force is applied, and is also used to make the abutting member 131 return to its initial position after moving towards the mounting hole 111. The limiting member 133 and the limiting boss 114 are used to limit the moving range of the abutting member 131, thereby preventing the abutting member 131 from detaching from the connection hole 113 and causing the structure to fail. In addition, the limiting member 133 abuts against one of the abutting member 131 and the limiting boss 114 and is fixedly connected to the other one, or the limiting member 133 abuts against the abutting member 131 and the limiting boss 114. In addition, the limiting boss 114 can be disposed on the hole wall of the connection hole 113. In addition, the elastic element 132 can be a spring.

[0038] Further, the abutting member 131 includes an abutting post 1311 and a pressing cover 1312. The abutting post 1311 is inserted into the connection hole 113. One end of the abutting post 1311 is located inside the connection hole 113, and the other end is located outside the connection hole 113. The pressing cover 1312 is provided at one end of the abutting post 1311 away from the connection hole 113. There is a limiting groove 13111 on the outer side wall of the limiting post. The limiting member 133 is provided in the limiting groove 13111 and protrudes from the outer side wall of the abutting post 1311. Both sides of the limiting member 133 are respectively abutted against the groove wall of the limiting groove 13111 and the side surface of the limiting boss 114 relative to the knife box 12. The elastic element 132 is sleeved on the outer side of the abutting post 1311. Both ends of the elastic element 132 are respectively connected to the knife holder 11 and the side surface of the pressing cover 1312 relative to the connection hole 113.

[0039] Among them, the above structure makes the abutting post 1311, the pressing cover 1312, the elastic element 132 and the limiting ring coaxially arranged, so that when performing the pressing action and the reset action, the axial force is evenly distributed, reducing the probability of the abutting post 1311 tilting and jamming during the movement, and thus ensuring the user experience; in addition, the abutting post 1311 can be slidably connected to the connection hole 113.

[0040] Further, an accommodating groove 115 is annularly provided on the outer surface of the knife holder 11 around the connection hole 113. An inner ring boss 116 is provided on the bottom of the accommodating groove 115 around the connection hole 113. The elastic element 132 is sleeved on the outer side of the inner ring boss 116. Both ends of the elastic element 132 are respectively connected to the bottom of the accommodating groove 115 and the side surface of the pressing cover 1312 relative to the connection hole 113. The abutting member 131 further includes a cover wall 1313. The cover wall 1313 is provided on the side surface of the pressing cover 1312 relative to the connection hole 113 and is sleeved on the outer side of the elastic element 132. The cover wall 1313 is inserted into the accommodating groove 115, and the cover wall 1313 and the pressing cover 1312 protrude outside the accommodating groove 115.

[0041] Among them, the cover wall 1313 is inserted into the accommodating groove 115, the cover wall 1313 is sleeved on the outer side of the elastic element 132, and the elastic element 132 is sleeved on the outer side of the inner ring boss 116, forming a multi-layer nested structure to limit the radial deformation of the elastic element 132, avoiding skew or offset during its compression and extension, ensuring the stable transmission of the elastic force along the axial direction of the connection hole 113, and improving the linearity and reliability of the movement of the separation assembly 13; in addition, the cover wall 1313 can be slidably connected to the accommodating groove 115.

[0042] Further, an outer ring boss 117 is provided around the outer surface of the tool rest 11 around the accommodation groove 115. There is a first transition arc surface 1171 at the junction between the tool rest 11 and the outer ring boss 117. The edge of the outer ring boss 117 away from the tool rest 11 and away from the pressing cover 1312 is provided with a second transition arc surface 1172. There is a third transition arc surface 1314 at the junction between the outer side surface of the pressing cover 1312 and the outer side surface of the cover wall 1313, so that the outer side of the separation assembly 13 and the part of the tool rest 11 near the flow splitting assembly have a relatively smooth surface, to improve the user's feeling of pushing the separation assembly 13, and also can improve the visual effect of the cutter head.

[0043] Further, the knife box 12 includes a box body 122 and a connecting member 123. The box body 122 is arranged through the protruding hole 112. The connecting member 123 is arranged on the side surface of the box body 122 relative to the connecting hole 113. The connecting member 123 abuts against the hole wall of the mounting hole 111. The clamping portion 121 is arranged on the side surface of the connecting member 123 relative to the connecting hole 113 and is inserted into the connecting hole 113; when the separation assembly 13 moves towards the mounting hole 111 and pushes the clamping portion 121, the connecting member 123 elastically deforms, so that the clamping portion 121 moves towards the box body 122.

[0044] Wherein, the clamping portion 121 is inserted into the connecting hole 113 to limit the left - right movement of the knife box 12. The connecting member 123 generates a radial pre - tightening force through elastic deformation to tightly abut against the hole wall of the mounting hole 111, to limit the movement of the knife box 12 in directions other than the left - right direction, and reduce the shaking or loosening during shaving. The two cooperate to fixedly arrange the knife box 12 on the tool rest 11.

[0045] Further, the box body 122 includes a protruding part and a mounting part. The protruding part is arranged on the side surface of the mounting part. The mounting part is located in the mounting hole 111. The protruding part passes through the protruding hole 112 and extends outside the protruding hole 112. The mounting part is connected to the hole wall of the mounting hole 111. Wherein, the blade can be mounted on the protruding part.

[0046] Further, a connecting portion 1221 protrudes from the side surface of the box body 122 relative to the connecting hole 113. The connecting member 123 is connected to the side surface of the connecting portion 1221 relative to the left - right direction. There is a deformation gap 124 between the connecting member 123 and the box body 122; wherein, two connecting portions 1221 can be provided on the side surface of the box body 122 relative to the connecting hole 113.

[0047] Among them, the connecting part 1221 on the side of the box body 122 serves as the fixed fulcrum of the connecting piece 123. When the connecting piece 123 is subjected to the thrust of the separating component 13, it elastically bends towards the box body 122 with the connecting part 1221 as the axis. The deformation gap 124 provides enough bending space for the connecting piece 123 to ensure that the clamping part 121 can be smoothly separated. Further, a force arm is formed between the connecting part 1221 and the clamping part 121, enabling the user to push the clamping part 121 out of the connecting hole 113 with a relatively small thrust.

[0048] Further, two of the connecting parts 1221 are provided at intervals in the left - right direction on the side of the box body 122 relative to the connecting hole 113. The connecting piece 123 is located between the two connecting parts 1221. The two ends of the connecting piece 123 are respectively connected to the sides of the two connecting parts 1221. The connecting piece 123 is further provided with two upturned parts 1231, which are respectively located between the clamping part 121 and one of the connecting parts 1221, and between the clamping part 121 and the other connecting part 1221. The upturned parts 1231 arc - upturn towards the direction away from the box body 122.

[0049] Among them, the two ends of the connecting piece 123 are respectively fixedly connected to the two connecting parts 1221, forming an elastic beam structure with both ends fixed - supported, which can prevent the tool box 12 from tilting. Further, the two upturned parts 1231 are respectively located between the clamping part 121 and the left - right connecting parts 1221, forming symmetric elastic deformation units, and the upturned parts 1231 both arc - upturn towards the direction away from the box body 122 to define the deformation direction of the connecting piece 123. When the separating component 13 pushes the clamping part 121, the two upturned parts 1231 on both sides continue to undergo arc - shaped deformation towards the direction away from the box body 122 to ensure that the clamping part 121 disengages from the connecting hole 113 in a straight line, avoiding jamming caused by uneven force and further improving the reliability of the disassembly process.

[0050] Further, the width of the deformation gap 124 gradually increases from the connecting part 1221 to the clamping part 121, so that the deformation gap 124 near the connecting part 1221 is smaller and the deformation gap 124 near the clamping part 121 is larger, to reduce the local stiffness of the connecting part 1221 at the position near the clamping part 121, enabling the thrust applied by the user to the separating component 13 to be more efficiently converted into the displacement of the clamping part 121, thereby effectively reducing the operating force required by the user to push the clamping part 121 away, reducing the user's operation difficulty and improving the user's handling feel.

[0051] Further, a first guiding portion 1111 is provided at the orifice of the mounting hole 111, and a second guiding portion 125 is provided on one side of the tool magazine 12 in the left - right direction. The first guiding portion 1111 and the second guiding portion 125 are used to guide the tool magazine 12 into the mounting hole 111.

[0052] Among them, when the tool magazine 12 is inserted into the mounting hole 111, the guiding portion abuts against the orifice of the mounting hole 111, the guiding portion abuts against the edge of the end of one side of the tool magazine 12, or the two guiding portions abut against each other. By moving along the guiding portion, the tool magazine 12 is guided into the mounting hole 111, thereby reducing the precision required for the operation of inserting the tool magazine 12 into the mounting hole 111. This enables the user not to carefully align the tool magazine 12 with the mounting hole 111 when installing the tool magazine 12, reducing the number of times the user needs to install repeatedly, and further making the operation of replacing the blade simpler, more convenient, and faster. Among them, the first guiding portion 1111 and the second guiding portion 125 can be composed of inclined surfaces, can also be composed of arc surfaces, or can be jointly composed of inclined surfaces and arc surfaces.

[0053] In other embodiments, only the first guiding portion 1111 is provided at the orifice of the mounting hole 111, or only the second guiding portion 125 is provided on one side of the tool magazine 12 in the left - right direction.

[0054] This embodiment also relates to a shaving device, which includes a grip 2 and the aforementioned razor blade 1, and the razor blade 1 is installed on the grip 2.
