Description

Technical Field

[0001] The invention relates to a shaver, in particular to a shaver which is easy to control. Background Art

[0002] At present, most of the shavers, especially those used for shaving body hair, have a cylindrical or flat elongated structure in appearance, no matter the cutter head is lateral or straight.

[0003] For example, the patent applications with announcement numbers CN207606889U, CN204094818U, and CN205415708U all have the above-mentioned shapes, which are defective when used: first, the outer shell surface of such shavers is smooth, and the shavers are prone to slipping when held by users, especially when the palms of users are sweaty, making it even more difficult to control the shavers. Secondly, when users are shaving uneven areas or areas where the field of vision is blocked, they need to rotate the shavers so that the blades can be close to the skin. However, such shavers are not easy to rotate due to their smooth surface, and the rotation range is also difficult to control, which makes it easy for the shavers to not be shaved cleanly enough or for the blades to scratch the skin. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a shaver that is easy to control, and provides users with two different control hand shapes to cope with different shaving situations, making it easier to control.

[0005] The present invention is achieved through the following technical solutions.

[0006] A shaver that is easy to control, comprising a basically slender tool and a cutter head arranged at the head end of the tool; the side of the tool has an annular groove that is inwardly concave and surrounds the tool, and the annular groove is formed with two clamping sections with a larger groove width and a control section with a smaller groove width that are connected end to end along its extension direction; the groove width of the clamping section gradually decreases from the middle to both sides; the clamping section is used for at least partially embedding the pads of the thumb and middle finger, or for at least partially embedding the sides of the index finger and middle finger; the control section is used for at least partially embedding the tip of the ring finger or the little finger.

[0007] As a further improvement of the present invention, a first groove edge of the clamping section close to the head end of the tool is arched, and a second groove edge of the clamping section close to the tail end of the tool is arc-shaped along the extending direction of the clamping section.

[0008] As a further improvement of the present invention, the first groove wall formed between the first groove edge and the groove bottom of the clamping section has an overall inclination relative to the radial surface of the device that is greater than the second groove wall formed between the second groove edge and the groove bottom.

[0009] As a further improvement of the present invention, the area of ​​the first groove wall is larger than that of the second groove wall.

[0010] As a further improvement of the present invention, the groove width of the control section gradually decreases from both ends to the middle.

[0011] As a further improvement of the present invention, the third groove edge of the control section close to the head end of the device and the fourth groove edge of the control section close to the tail end of the device are arched in opposite directions.

[0012] As a further improvement of the present invention, the third groove wall formed between the third groove edge and the groove bottom of the control section has an overall inclination relative to the radial surface of the device that is smaller than the fourth groove wall formed between the fourth groove edge and the groove bottom.

[0013] As a further improvement of the present invention, the bottom of the annular groove is in the shape of an annular belt with a certain width and is coaxial with the device.

[0014] As a further improvement of the present invention, the portion of the tool between the annular groove and the tail end of the tool is a prismatic structure.

[0015] As a further improvement of the present invention, the tool has a flange structure formed along the first groove edge and the third groove edge, and the shaver also includes a cover for snapping onto the part of the tool between the annular groove and the head end of the tool, and the edge of the bottom end of the cover abuts against the flange structure.

[0016] Beneficial effects of the present invention:

[0017] The present invention provides the user with two different control hand shapes through the annular groove, which respectively deal with the situation where the shaved area is uneven and the field of vision is blocked, and the situation where the shaved area is smooth and flat, making it easy to control the shaver to implement efficient and safe shaving operations; in addition, the structural design of the annular groove is very suitable for female users and is highly user-friendly.

[0024] The present invention is further described in detail below based on the accompanying drawings and implementation examples.

[0025] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. The words "inside" and "outside" refer to the direction toward or away from the geometric center of a specific component, respectively. They are relative concepts, and therefore may change accordingly according to different locations and different usage conditions. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0026] Reference Figure 1-Figure 5 A shaver that is easy to control, including a basically slender tool 1 and a cutter head arranged at the head end 11 of the tool. The tool 1 is specifically cylindrical in shape in this embodiment. The side of the tool 1 has an annular groove that is recessed inward and surrounds the tool 1. The annular groove is formed with two clamping sections 21 with a larger groove width and a control section 22 with a smaller groove width that are connected end to end along its extension direction.

[0027] The groove width of the clamping section 21 gradually decreases from the middle to both sides and naturally transitions to the control section 22. The maximum groove width of the clamping section 21 is slightly smaller than the length of the pads of the thumb and the middle finger, and the straight-line distance between the two ends of the clamping section 21 is slightly smaller than the length of the middle sections of the index finger and the middle finger. Therefore, the pads of the thumb and the middle finger can be partially embedded in the two clamping sections 21 at the same time, or the opposite side of the middle sections of the index finger and the middle finger can be partially embedded in the two clamping sections 21 at the same time.

[0028] The slot width of the manipulation section 22 is smaller than the slot width of the clamping section 21 , so that the fingertip of the ring finger or the little finger can be embedded in the manipulation section 22 .

[0029] Based on the groove width setting and groove width variation of the clamping section 21 and the control section 22, the user has two different control hand shapes.

[0030] The first control hand shape: the user partially embeds the tips of the thumb and middle finger into the two clamping sections 21 , embeds the fingertip of the ring finger or little finger into the control section 22 , and embeds the fingertip of the index finger into the intersection of the two clamping sections 21 .

[0031] The second control hand shape: the user embeds the sides of the index finger and the middle finger into the two clamping sections 21 respectively, so that the index finger and the middle finger are in a clamping posture on the instrument 1, and the thumb is pressed against the tail end 12 of the instrument. The specific embedding position of the index finger and the middle finger can be the distal phalanx or the middle phalanx.

[0032] There are two main situations that users may encounter when shaving. The first shaving situation: the shaved area is not smooth and flat, such as underarms, private parts, etc. The second shaving situation: the shaved area is smooth and flat, such as thighs, arms, etc.

[0033] The first type of control hand shape is mainly used to deal with the first type of shaving situation. In this case, it is necessary to frequently adjust the direction of the head end 11 of the device so that the blade can fit on the skin for shaving. The user partially embeds the pads of the thumb and middle finger into the two clamping sections 21, so that the device 1 forms a rotating axis between the thumb and the middle finger, and the ring finger or little finger is embedded in the control section 22. The device 1 is rotated by the ring finger or little finger, so as to control the direction of the head end of the device 1, so that the blade can fit on the skin for shaving. Compared with the existing technology, the control flexibility is higher, and the three fingers embedded in the annular groove 2 make the shaver not easy to slip. In addition, the fingertip of the index finger can be embedded in the connection between the two clamping sections 21, and the rotation of the device 1 is assisted by the index finger.

[0034] The second control hand shape is mainly used to deal with the second shaving situation. In this case, the direction adjustment requirement for the head end 11 of the tool is not high, and it is necessary to stably control the shaver for reciprocating shaving. The user embeds the side part of the distal phalanx or the middle phalanx of the index finger and the middle finger into the two clamping sections 21, and then presses the thumb against the tail end of the tool 1, thereby forming a V-shaped clamp of the index finger and the middle finger on the tool 1, and then cooperates with the thumb to form a three-point support hand shape. Under this hand shape, it will be very stable to shave the shaver back and forth on the skin, thereby improving the shaving efficiency; moreover, the strength of the head end of the tool 1 pressing on the skin can be controlled by the strength of the thumb to prevent skin damage.

[0035] The groove edge of the clamping section 21 close to the tool head end 11 is defined as the first groove edge 211, the groove edge close to the tool tail end 12 is defined as the second groove edge 212, the groove wall between the first groove edge 211 and the groove bottom 2-C is defined as the first groove wall 21-A, and the groove wall between the second groove edge 212 and the groove bottom 2-C is defined as the second groove wall 21-B. The groove edge of the control section 22 close to the tool head end 11 is defined as the third groove edge 221, the groove edge close to the tool tail end 12 is defined as the fourth groove edge 222, the groove wall between the third groove edge 221 and the groove bottom 2-C is defined as the third groove wall 22-A, and the groove wall between the fourth groove edge 222 and the groove bottom 2-C is defined as the fourth groove wall 22-B.

[0036] When the user uses the second control hand shape, the index finger, middle finger and thumb are hooked, and the index finger and middle finger are naturally bent. The clamping section 21 extends from one end connecting the adjacent clamping sections 21 to the other end connecting the control section 22, and is inclined toward the tool tail end 12, so that the overall extension direction of the clamping section 21 is consistent with the direction of the middle section of the index finger and middle finger after the natural bending.

[0037] The first groove edge 211 is arched, and its shape conforms to the arc shape of the thumb and middle finger tips. When the user uses the first control hand shape, the thumb and middle finger tips are close to the first groove edge 211, so that the thumb and middle finger pads are easier to fit into the clamping section 21 of the annular groove 2. In addition, the end of the first groove edge 211 close to the control section 22 is closer to the tool tail end 12 than the other end, so that the first groove edge 211 presents an arched direction slightly inclined to the axial direction of the tool 1, so that the thumb and middle finger can be inserted obliquely to the side of the shaver.

[0038] The second groove edge 212 is in an arc shape along the extension direction of the clamping section 21. When the user uses the second control hand shape, the index finger and the middle finger are pressed against the second groove edge 212, which makes it easy for the side of the distal phalanx or the middle phalanx of both to be embedded in the clamping section 21 of the annular groove 2. In addition, the index finger and the middle finger can also be used to lift the shaver, and the thumb can be used to press the tail end 12 of the tool to press down the shaver, so that the pressure of the head end of the tool 1 on the skin can be adjusted more accurately.

[0039] The overall inclination of the first groove wall 21-A relative to the radial surface of the device 1 is greater than that of the second groove wall 21-B. When the user uses the first control hand shape, most of the pads of the thumb and middle finger are tightly attached to the first groove wall 21-A. Therefore, the relatively small inclination of the first groove wall 21-A relative to the second groove wall 21-B makes it easier for the pads of the thumb and middle finger to stick tightly to the first groove wall 21-A. In addition, the area of ​​the first groove wall 21-A is also larger than that of the second groove wall 21-B, thereby providing a larger contact area to support the pads of the thumb and middle finger, so that the thumb and middle finger can hold the device 1 more stably and are not easy to slip.

[0040] The groove width of the control section 22 gradually decreases from both ends to the middle, and the third groove edge 221 and the fourth groove edge 222 of the control section 22 are mutually reversed arches. The control section 22 presents a long and narrow shape as a whole. When the user uses the first control hand shape, the fingertip of the ring finger or the little finger can be embedded from any position of the control section 22, making the control more casual and convenient. Moreover, the change of the groove width of the control section 22 also facilitates the fingertip of the ring finger or the little finger to be embedded from one side to the middle of the control section 22. The shape design of the third groove edge 221 and the fourth groove edge 222 allows the third groove edge 221 and the fourth groove edge 222 to naturally gather toward the middle during the embedding process of the fingertip, so as to avoid pinching the fingertip. In addition, some female users have long nails, and the long and narrow control section 22 can also accommodate the nails, which is very suitable for female users.

[0041] In addition, the overall inclination of the third groove wall 22 -A of the control section 22 relative to the radial surface of the device 1 is smaller than that of the fourth groove wall 22 -B, which is more convenient for the ring finger or the little finger to move.

[0042] The groove bottom 2-C of the annular groove is in the shape of an annular band with a certain width and is coaxial with the device 1, which is particularly suitable for female users, especially female users using the first type of control hand shape. When shaving body hair on the armpits, private parts and other parts, the rotation range of the shaver is difficult to control due to the obstruction of the field of vision. When the female user inserts the ring finger or little finger into the control section 22, the nail can be against the groove bottom 2-C, and the nail can be used to slide along the width direction of the groove bottom 2-C when rotating the device 1. When the nail touches the third groove wall 22-A or the fourth groove wall 22-B, there is a very obvious change in the hand feel, so as to give the user a reminder that the ring finger or little finger can continue to turn the device 1.

[0043] The portion of the tool 1 between the annular groove 2 and the tool tail end 12 is a prismatic structure, which can play an anti-slip role and prevent the tool 1 from slipping off the hand.

[0044] The tool 1 is formed with a circle of flange structure 13 along the first groove edge 211 and the third groove edge 221. The shaver also includes a cover 3 for snapping onto the part of the tool 1 between the annular groove 2 and the tool head end 11. The edge of the bottom end of the cover 3 abuts against the flange structure 13, and the cover also appears to be a prismatic structure.

[0045] Based on the structural shape of the annular groove 2, a "canyon" structure is presented around the device 1 as a whole, which not only allows the device 1 to support two different types of control hands to deal with different situations of body hair. In addition, the device 1 (including the cover) is generally prismatic in shape, and the "canyon" design of the annular groove 2 makes the product very beautiful and artistic, thereby enhancing the commercial value of the product.

[0046] Finally, it should be noted that the above implementation cases are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned implementation cases, those skilled in the art should understand that they can still modify the technical solutions recorded in the aforementioned implementation cases, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the implementation cases of the present invention.
