Description

Technical Field

[0001] The utility model relates to the technical field of electric shavers, and particularly relates to an electric shaver. Background Art

[0002] An electric shaver is an electrical appliance that uses electricity to drive a blade to shave beards and sideburns. A relatively typical one is a reciprocating electric shaver. The cutter head of this electric shaver is installed on the upper part of the shaver body. The shaver body is composed of components such as a driving device, a power supply, and an operation switch. The driving device drives the cutter head to swing back and forth under the drive of electricity, and the moving blade cooperates with the fixed static blade to cut off the beards and sideburns.

[0003] Due to the limitations of the structural design, the cutter head part of traditional electric shavers often maintains a fixed angle with the main body part and is not adjustable. When a user uses the shaver to shave, in order to make the cutter head fit the beards on different parts of the face, the user can only swing the main body by hand to change the angle of the cutter head relative to the face, which reduces the shaving ability of the shaver and the user experience to a certain extent. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide an electric shaver to solve the problem that the cutter head part of traditional electric shavers often maintains a fixed angle with the main body part, and the user can only swing the main body by hand to change the angle of the cutter head relative to the face.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is as follows:

Both ends of the first slide bar are respectively connected to the first base plate and the second base plate. The first base plate is provided with a first guiding through hole, and the second base plate is provided with a second guiding through hole;

[0010] One end of the first sliding seat is provided with a first guiding shaft extending along its sliding direction, and the other end is provided with a second guiding shaft extending along its sliding direction. The first guiding shaft penetrates through the first guiding through hole, and the second guiding shaft penetrates through the second guiding through hole.

[0011] Even more preferably, the free end of the first guiding shaft and / or the second guiding shaft is a split end;

[0012] And / or, the head of the electric shaver is further provided with a second cutter holder for mounting a moving cutter. A second slide bar is further horizontally arranged on the mounting frame. Both ends of the second slide bar are respectively connected to the first base plate and the second base plate. The second slide bar is sleeved with a second sliding seat slidably connected thereto. A second connecting member for connecting the second cutter holder is arranged at the top of the second sliding seat;

[0013] The mounting frame is further provided with a third connecting member. One end of the third connecting member is hinged to the first sliding seat, and the other end is hinged to the second sliding seat. The middle part of the third connecting member is rotatably connected to the mounting frame.

[0014] Even more preferably, one end of the second sliding seat is provided with a third guiding shaft extending along its sliding direction, and the other end is provided with a fourth guiding shaft extending along its sliding direction. The third guiding shaft penetrates through the first guiding through hole, and the fourth guiding shaft penetrates through the second guiding through hole;

[0015] And / or, a first fixing seat is provided at the bottom of the mounting frame. A first fixing shaft is embedded in the first fixing seat. After the first fixing shaft extends out of the first fixing seat, it is inserted into the third connecting member and is rotatably connected to the third connecting member.

[0016] Even more preferably, the free end of the third guiding shaft and / or the fourth guiding shaft is a split end;

[0017] And / or, a first rib plate is arranged on the outer surface of the first fixing seat, and the first rib plate extends to the first guiding through hole and is connected to the first base plate.

[0018] Further preferably, the mounting bracket is further provided with a fourth connecting member. The third connecting member and the fourth connecting member are arranged at intervals along the sliding direction of the first sliding seat. One end of the fourth connecting member is hinged to the first sliding seat, the other end is hinged to the second sliding seat, and the middle part of the fourth connecting member is rotatably connected to the mounting bracket.

[0021] The beneficial effects of the electric shaver according to the present invention compared with the prior art are mainly reflected in:

[0022] The top of the first sliding seat of the electric shaver of the present invention is connected to the first cutter head frame, and the first sliding seat is connected to the output shaft. When the output shaft rotates, the first sliding seat can be driven to reciprocate horizontally relative to the main body of the electric shaver, and then drive the first cutter head frame to reciprocate horizontally to realize the shaving function;

[0023] By providing the connecting seat, and connecting one end of the connecting seat to the main body and the other end to the transverse hinge shaft of the head, the angle of the head relative to the main body can be changed in the longitudinal plane. When the user shaves, the first cutter head frame will rotate adaptively due to the rotation of the head, so as to independently adjust the angle relative to the main body part to adapt to the change of the facial curve. It can solve the problem that the cutter head part of the traditional electric shaver often maintains a fixed angle with the main body part, and the user can only change the angle of the cutter head relative to the face by manually swinging the main body. And because the hinge shaft is in the same direction as the reciprocating sliding direction of the first cutter head frame, it will not affect the horizontal reciprocating movement of the first cutter head frame;

[0024] Since the cutter head part of the shaver of the present invention can adaptively change the angle relative to the main body as the user moves it on the face, the top side of the cutter head can adaptively fit the human face, the shaving ability is stronger, and the user experience is better.

Specific embodiments

[0039] The technical solution of the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it. However, the embodiments cited are not intended to limit the present utility model. In this embodiment, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model, 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 limiting the present utility model.

[0040] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element and integrated with it, or there may be an intermediate element at the same time. The terms "installation", "one end", "the other end" and similar expressions used in the present utility model are only for the purpose of illustration.

[0041] This embodiment provides an electric shaver, as Figures 1 to 6 shown, including a head 100, a main body 200 and a connecting seat 400. The head 100 is provided with a first sliding seat 2 that can reciprocate horizontally and a first tool rest 26 for installing a moving blade. A driving device is provided in the main body 200. The driving device is provided with an output shaft 4. The top of the first sliding seat 2 is connected to the first tool rest 26, and the bottom of the first sliding seat 2 is connected to the output shaft 4. After the output shaft 4 rotates, it can drive the first sliding seat 2 to reciprocate horizontally. One end of the connecting seat 400 is connected to the main body 200, and the other end is hinged to the head 100 along the horizontal hinge shaft 25.

[0042] The top of the first sliding seat 2 of the electric shaver of the present utility model is connected to the first tool rest 26, and the first sliding seat 2 is connected to the output shaft 4. After the output shaft 4 rotates, it can drive the first sliding seat 2 to reciprocate horizontally relative to the main body 200, and then drive the first tool rest 26 to reciprocate horizontally to achieve the shaving function;

[0043] By providing a connecting seat 400, connecting one end of the connecting seat 400 to the main body 200 and the other end to the head 100 through a lateral hinge shaft 25, the angle of the head 100 relative to the main body 200 can be changed in the longitudinal plane. When the user shaves, the first cutter holder 26 will rotate adaptively due to the rotation of the head 100, thereby autonomously adjusting the angle relative to the main body 200 to adapt to the changes in the facial curve. This can solve the problem that the cutter head part of traditional electric shavers often maintains a fixed angle with the main body part, and the user can only change the angle of the cutter head relative to the face by manually swinging the main body part. Moreover, since the hinge shaft 25 is in the same reciprocating sliding direction as the first cutter holder 26, it will not affect the lateral reciprocating movement of the first cutter holder 26;

[0044] Since the cutter head part of the electric shaver of the present utility model can adaptively change the angle relative to the main body 200 as the user moves it on the face, the top side of the cutter head can adaptively fit the human face, resulting in stronger shaving ability and better user experience.

[0045] In a preferred embodiment, as Figure 2 and Figure 8 shown, a longitudinally extending slot 5 is provided at the bottom of the first sliding seat 2. After the output shaft 4 is inserted into the slot 5, it is rotatably connected to the first sliding seat 2. Specifically, the slot 5 is composed of two parallel and spaced-apart baffles 501. An eccentric shaft is connected to the output shaft 4 and is inserted between the two baffles 501. When the eccentric shaft rotates, it can repeatedly push the two baffles 501, thereby driving the first sliding seat 2 to reciprocate.

[0046] In another preferred embodiment, as Figure 3 and Figure 7 shown, the head 100 is provided with a mounting bracket 300. A first sliding rod 1 is horizontally arranged on the mounting bracket 300. The first sliding seat 2 is sleeved on the first sliding rod 1 and is slidably connected to the first sliding rod 1. A first connecting member 3 is provided at the top of the first sliding seat 2, and the first connecting member 3 is connected to the first cutter holder 26.

[0047] In a further preferred embodiment, as Figure 6 and Figure 7As shown in the figure, a first base plate 6 and a second base plate 7 are provided at the bottom of the mounting bracket 300. Both ends of the first slide bar 1 are respectively connected to the first base plate 6 and the second base plate 7. The first base plate 6 is provided with a first guiding through hole 8, and the second base plate 7 is provided with a second guiding through hole 9. One end of the first sliding seat 2 is provided with a first guiding shaft 10 extending along its sliding direction, and the other end is provided with a second guiding shaft 11 extending along its sliding direction. The first guiding shaft 10 penetrates through the first guiding through hole 8, and the second guiding shaft 11 penetrates through the second guiding through hole 9. During the horizontal reciprocating sliding of the first sliding seat 2, the first guiding shaft 10 will reciprocally slide in the first guiding through hole 8, and at the same time, the second guiding shaft 11 will reciprocally slide in the second guiding through hole 9. In this way, the direction stability of the horizontal sliding of the first sliding seat 2 can be improved, and the vibration can be reduced. As a preferred example, the first guiding shaft 10 and the second guiding shaft 11 are integrally formed with the first sliding seat 2.

[0048] Furthermore, when processing the above-mentioned first guiding shaft 10 and second guiding shaft 11 by processes such as injection molding, it is inevitable that there will be machining tolerances. If the processed size is too small, there will be a gap between the above-mentioned guiding shaft and the corresponding guiding through hole, and the guiding effect will be reduced. If the processed size is too large, there will be a large frictional force between the above-mentioned guiding shaft and the corresponding guiding through hole, and even impacts and squeezes will occur between the guiding shaft and the corresponding guiding through hole, which is not conducive to vibration reduction and noise reduction, and will also shorten the service life of the parts. Therefore, in a preferred embodiment, as Figure 8 shown in the figure, the free ends of the first guiding shaft 10 and the second guiding shaft 11 are set in the form of a split opening. In this embodiment, the end of the first guiding shaft 10 facing the first guiding through hole 8 forms two parts on the left and right, and there is a concave hollow groove 12 between the two parts on the left and right. This concave hollow groove 12 is the deformation space for the two parts on the left and right of the first guiding shaft 10. When the first guiding shaft 10 slides in the first guiding through hole 8, its two parts on the left and right can deform through this concave hollow groove 12 when being squeezed by the hole wall, so as to be able to cope with the problem when the above-mentioned processed size is too large, and play the role of vibration reduction and noise reduction and extending the service life. The principle that the end of the second guiding shaft 11 facing the second guiding through hole 9 forms two parts on the left and right is the same as above, and will not be elaborated. Of course, in other embodiments, the free end of the first guiding shaft 10 or the second guiding shaft 11 can also be circumferentially set to more than three parts, and there is a gap for deformation after being squeezed between every two adjacent parts.

[0049] Furthermore, as Figure 3 、 7 、9 and Figure 10As shown, the head 100 of the electric shaver is further provided with a second cutter holder 27 for installing the moving cutter. A second sliding rod 13 is also horizontally arranged on the mounting frame 300. The two ends of the second sliding rod 13 are respectively connected to the first seat plate 6 and the second seat plate 7. A second sliding seat 14 which is slidably connected to the second sliding rod 13 is sleeved on the second sliding rod 13. A second connecting member 15 for connecting the second cutter holder 27 is arranged at the top of the second sliding seat 14. The mounting frame 300 is further provided with a third connecting member 16. One end of the third connecting member 16 is hinged to the first sliding seat 2, and the other end is hinged to the second sliding seat 14. The middle part of the third connecting member 16 is rotatably connected to the mounting frame 300. In this embodiment, the second sliding seat 14 can slide in the opposite direction synchronously with the first sliding seat 2 under the drive of the third connecting member 16, so as to drive the second cutter holder 27 to reciprocate. The shaver in this embodiment can support the simultaneous setting of two cutter holders, and the synchronism of the two cutter holders is good, and the structural design is compact. Specifically, a first fixed seat 18 is arranged at the bottom of the mounting frame 300. A first fixed shaft (not shown in the figure) is embedded in the first fixed seat 18. After the first fixed shaft extends out of the first fixed seat 18, it is inserted into the third connecting member 16 and is rotatably connected to the third connecting member 16. Further, the first fixed seat 18 is tubular, and first rib plates 20 extending radially along both sides of the first fixed shaft are respectively arranged on the outer surface of the first fixed seat 18. And one of the first rib plates 20 on one side extends to the first guiding through hole 8 and is connected to the first seat plate 6, which can not only improve the stability of the first fixed seat 18, but also reinforce the first seat plate 6.

[0050] Preferably, in order to improve the synchronism of the sliding of the second sliding seat 14 and the first sliding seat 2, the mounting frame 300 is further provided with a fourth connecting member 17. The third connecting member 16 and the fourth connecting member 17 are arranged at intervals along the sliding direction of the first sliding seat 2. One end of the fourth connecting member 17 is hinged to the first sliding seat 2, and the other end is hinged to the second sliding seat 14. The middle part of the fourth connecting member 17 is rotatably connected to the mounting frame 300. By adding the fourth connecting member 17, the pushing and pulling force received by the second sliding seat 14 can be increased, and the synchronism of the sliding of the second sliding seat 14 and the first sliding seat 2 can be further ensured. Specifically, as Figure 11 shown, the third connecting member 16 and the fourth connecting member 17 are arranged in parallel and symmetrically, and are respectively located at both ends of the second sliding seat 14, so that the hinge points of the third connecting member 16 with the first sliding seat 2 and the second sliding seat 14, and the hinge points of the fourth connecting member 17 with the first sliding seat 2 and the second sliding seat 14 form a parallelogram that can deform smoothly in reciprocation. At the same time, enough space can also be reserved between the third connecting member 16 and the fourth connecting member 17 to facilitate the arrangement of the connection structure between the output shaft 4 of the driving device and the first sliding seat 2.

[0051] As Figure 8As shown, in this embodiment, a fifth connecting member 22 is further provided at the top of the first sliding seat 2 and arranged at intervals with the first connecting member 3. The fifth connecting member 22 can be used to connect and install the third tool rest 28 of the moving knife, and thus can support the design of a razor with three tool rests. It should be noted that at this time, the first connecting member 3 and the fifth connecting member 22 slide synchronously and in the same direction.

[0052] As Figure 7 shown, a second fixed seat 19 is provided at the bottom of the mounting frame 300. A second fixed shaft (not shown in the figure) is embedded in the second fixed seat 19. After the second fixed shaft extends out of the second fixed seat 19, it is inserted into the fourth connecting member 17 and is rotatably connected to the fourth connecting member 17. The second fixed seat 19 is tubular, and second rib plates 21 extending radially along its two sides of the second fixed shaft are respectively provided on its outer surface, and one side of the second rib plates 21 extends to the second guiding through hole 9 and is connected to the second seat plate 7, which can improve the stability of the second fixed seat 19 and also play a reinforcing role for the second seat plate 7.

[0053] The above-mentioned first sliding rod 1 and second sliding rod 13 can be made of stainless steel cylinders, which are corrosion-resistant, not easily deformed, and it is easy to obtain a small friction coefficient on their surfaces, so as to facilitate the smooth sliding of the first sliding seat 2 and the second sliding seat 14.

[0054] In a preferred embodiment, as Figure 6 and Figure 9 shown, one end of the second sliding seat 14 is provided with a third guiding shaft 23 extending along its sliding direction, and the other end is provided with a fourth guiding shaft 24 extending along its sliding direction. The third guiding shaft 23 penetrates through the first guiding through hole 8, and the fourth guiding shaft 24 penetrates through the second guiding through hole 9. As previously stated, similarly, during the lateral reciprocating sliding of the second sliding seat 14, the third guiding shaft 23 will reciprocate in the first guiding through hole 8, and at the same time, the fourth guiding shaft 24 will reciprocate in the second guiding through hole 9. This can improve the direction stability of the lateral sliding of the second sliding seat 14 and reduce vibration. It can be understood that the third guiding shaft 23 and the fourth guiding shaft 24 can also be integrally formed with the second sliding seat 14, and the free ends of the first guiding shaft 10 and the second guiding shaft 11 are set in a forked form, so as to reduce the vibration generated when the first guiding shaft 10 and the second guiding shaft 11 reciprocally slide in the first guiding through hole 8 and the second guiding through hole 9 during the high-frequency reciprocating movement of the second sliding seat 14, reduce noise, and extend the service life of the second sliding seat 14.

[0055] It should be noted that the terms indicating directions such as "top", "bottom", "upper", etc. in the above description are based on the normal usage state when the shaving head is above the main body. It can be understood that when the actual usage state of the shaving razor changes, the above direction descriptions change accordingly, but this does not mean that these changes will exceed the scope of the solution of the present utility model.

[0056] In this specification, unless otherwise clearly defined and limited, a first feature being "on" or "under" a second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, a first feature being "above", "over" and "on top of" a second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the first feature has a higher horizontal height than the second feature. A first feature being "under", "below" and "beneath" a second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the first feature has a lower horizontal height than the second feature.

[0057] In the description of this specification, the description with reference to terms such as "preferred embodiment", "another embodiment", "other embodiments" or "specific examples", etc. means that the specific features, structures, materials or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples.
