The first embodiment.
As shown in fig. 1 to 3, a cutting unit according to an embodiment of the present invention may be applied to a shaving apparatus or a personal care product similar to the shaving apparatus. Moreover, the cutting unit of the present embodiment is mainly mounted on a head assembly of the shaving apparatus.
Specifically, the cutting unit includes a mounting frame 10 and an outer blade 20, and an inner blade (not shown) that cooperates with the outer blade 20 is added as occasion demands during an actual mounting or assembling process of the cutting unit. The mounting frame 10 is provided with a blade cavity 11 penetrating through upper and lower ends thereof, the blade cavity 11 being provided for mounting and supporting the outer blade 20, and also providing a space for the outer blade 20 to move. The outer cutter 20 is installed in the cutter chamber 11 to be exposed to the upper end of the mounting frame 10, the outer cutter 20 is installed in the cutter chamber 11 in a generally clearance-fitting manner, and a portion of the outer cutter 20 exposed to the upper end of the mounting frame 10 is used to be in contact with the skin of the human body to perform a shaving work. Further, the cutting unit further comprises a metal heat dissipation member 30, the metal heat dissipation member 30 is disposed on the mounting frame 10, and the metal heat dissipation member 30 at least partially surrounds the peripheral side of the outer blade 20 for contacting with the skin of the human body and reducing the heat sensation of the skin of the human body, i.e., the metal heat dissipation member 30 may be disposed on the peripheral side of the outer blade 20 in a semi-surrounding or fully-surrounding manner.
In the cutting unit according to the embodiment of the invention, since the metal heat dissipation member 30 is disposed on the mounting frame 10, and the metal heat dissipation member 30 at least partially surrounds the peripheral side of the outer blade 20, so that the area of the skin contacting the mounting frame 10 is reduced, the skin can be contacted with the metal heat dissipation member 30, and the metal heat dissipation member 30 has high thermal conductivity, that is, the temperature of the metal heat dissipation member 30 is generally substantially the same as the room temperature, and the body temperature of a person is generally higher than the room temperature, so that the skin can feel cool when contacting the metal heat dissipation member 30. Simultaneously because this metal heat dissipation part 30 no longer contacts with other electric parts that produce can be thermal, for example, the cutting unit in this embodiment no longer need use the thermocouple, thoroughly avoid on thermocouple self produced heat transfer to metal heat dissipation part 30, so can ensure when the skin that produces high temperature because outer blade 20 work and can give people brings uncomfortable sensation, this metal heat dissipation part 30 can absorb the heat on the skin effectively and give off, and then make the skin can cool down, promote the comfort of use greatly.
Furthermore, the cutting unit of the present embodiment does not require much increased power consumption when applied to a shaving apparatus, thereby ensuring that the shaving apparatus can be used for a longer period of time with a limited amount of power.
Preferably, the metal heat sink 30 is made of aluminum, iron, or stainless steel. That is, the molded metal heat dissipating member 30 is made of an aluminum material, an iron material, or a stainless material, and the metal heat dissipating member 30 made of the above material can reduce the thermal sensation of the skin of the human body when contacting the skin, and can absorb and dissipate the heat in the skin to improve the comfort of use.
Of course, in other embodiments, the metal heat dissipation member 30 may be made of other metal materials, such as aluminum alloy, which are not illustrated herein.
Further, the metal heat dissipation member 30 may be manufactured and molded by die casting, forging, or the like according to actual requirements.
In this embodiment, as shown in fig. 3 and fig. 6, the mounting groove 12 is disposed on the upper end surface of the mounting bracket 10 and located on the periphery of the outer blade 20, the mounting groove 12 is located on the periphery of the opening above the blade cavity 11 opened on the mounting bracket 10, that is, a certain distance is provided between the mounting groove 12 and the opening above the blade cavity 11, the distance is set according to the production requirement, the metal heat dissipation part 30 is embedded in the mounting groove 12 and can be stably maintained, the size of the mounting groove 12 is adjusted according to the actual requirement, as long as it is ensured that the metal heat dissipation part 30 after the installation can be embedded and installed, the metal heat dissipation part is not easy to fall off during. Specifically, the lower end and the structure of the metal heat dissipation part 30 near the lower end are embedded in the mounting groove 12, so that the upper end and the structure of the metal heat dissipation part 30 near the upper end are exposed to the upper end of the mounting frame 10, and the metal heat dissipation part 30 after being mounted has a part capable of effectively forming a structure with the skin. Meanwhile, the stability of the metal heat dissipation part 30 after installation can be effectively improved by the embedding mode.
Further, the mounting bracket 10 may be made of a plastic material, and the metal heat dissipation member 30 may be formed on the mounting bracket 10 by injection molding when the mounting bracket 10 is injection molded, so as to be embedded in the mounting groove 12 formed in the mounting bracket 10. The mounting bracket 10 having the mounting groove 12 may be formed by injection molding, and the metal heat dissipation member 30 may be inserted into the mounting groove 12 by interference fit at a later stage.
In this embodiment, as shown in fig. 2, the mounting groove 12 is a blind groove structure, a distance H is formed between the bottom wall of the mounting groove 12 and the lower end of the mounting bracket 10, and the depth of the mounting groove 12 is smaller than the height from the upper end to the lower end of the mounting bracket 10. Specifically, the mounting groove 12 of the blind groove structure can prevent the mounting groove 12 from penetrating through the upper and lower ends of the mounting frame 10, and the mounting groove 12 structure plugged at the bottom can prevent the metal heat dissipation part 30 from contacting with other electric parts (such as a thermocouple) which can generate heat to cause the heat on the non-skin to be transferred to the metal heat dissipation part 30, so that the metal heat dissipation part 30 is overheated and cannot absorb the heat on the skin, and further the cooling effect of the metal heat dissipation part 30 for the skin is influenced.
Further, as shown in fig. 2 and 5 to 6, the shape of the mounting groove 12 is adapted to the shape of the metal heat radiating member 30. Moreover, the width of the mounting groove 12 (i.e. the distance between two opposite inner side walls in the mounting groove 12) is slightly larger than the width of the metal heat dissipation part 30 (i.e. the distance between two opposite outer side walls outside the metal heat dissipation part 30), so that the metal heat dissipation part 30 is embedded in the mounting groove 12 and forms an interference fit with the mounting groove 12, i.e. the metal heat dissipation part 30 forms a tight fit with the mounting groove 12, and the stability and reliability of the metal heat dissipation part 30 embedded in the mounting groove 12 are greatly improved. The width of the mounting groove 12 is slightly larger than the width of the metal heat dissipation member 30, and is slightly larger than the width of the metal heat dissipation member 30, on the premise that the metal heat dissipation member 30 can be embedded into the mounting groove 12 and the structure of the mounting groove 12 is not damaged, the specific size of the larger size is set according to requirements, for example, the width of the mounting groove 12 is larger than the width of the metal heat dissipation member 30 by more than 0.1mm or less.
In addition, the shape of the mounting groove 12 is adapted to the shape of the metal heat dissipation part 30, that is, when the overall shape of the metal heat dissipation part 30 is regular, then the overall shape of the mounting groove 12 is also regular; when the metal heat dissipation part 30 is formed irregularly, the overall shape of the mounting groove 12 is also irregular, so that the mounting groove 12 can be matched with the metal heat dissipation part 30 in shape, and the metal heat dissipation part 30 can be conveniently embedded and mounted in the mounting groove 12.
Of course, the width of the mounting groove 12 may be equal to the width of the metal heat dissipation member 30, that is, the difference between the width of the mounting groove 12 and the width of the metal heat dissipation member 30 is zero or negligible. Such a design also enables the metal heat-radiating member 30 to be stably and reliably fitted in the mounting groove 12. For example, when the mounting block 10 is injection molded, the metal heat dissipation member 30 is integrally molded with the mounting block 10 in a mold, the metal heat dissipation member 30 is embedded in the mounting groove 12 formed on the mounting block 10, and the width of the mounting groove 12 is the same as or almost equal to the width of the metal heat dissipation member 30.
In the present embodiment, as shown in fig. 2 and 5, the metal heat-dissipating member 30 includes a cooling surface 31 at an upper end thereof, the cooling surface 31 is for contact with the skin of the human body, and the cooling surface 31 has an arc shape. The arc-shaped cooling surface 31 is arranged to increase the contact area between the metal heat dissipation part 30 and the skin and reduce the contact area between the upper end surface of the mounting frame 10 and the skin, so that the heat absorption effect of the metal heat dissipation part 30 on the skin is improved, the heat dissipation effect on the skin is improved, and the heat dissipation efficiency on the skin can be further improved; on the other hand, the cooling surface 31 in the arc shape can improve the comfort of contacting with the skin, namely, the cooling surface 31 in the arc shape is smoother, the unsmooth feeling of the skin when contacting with the contact surface can be effectively reduced during shaving, and the comfort of use is further improved.
Preferably, as shown in fig. 2 and 5, the cooling surface 31 at the upper end of the metal heat sink 30 is formed by rounding at the corner between the two opposite outer side walls of the metal heat sink and the upper end surface. Further, there is a smooth, corner-free transition between the rounded corners and the upper end surface of the metal heat sink 30.
Further, the metal heat dissipation member 30 may have a solid structure or a hollow structure, and for example, the cross section of the entire structure may have an "n" shape.
The cooling surface 31 at the upper end of the metal heat-dissipating member 30 may be treated by polishing or the like to form a smooth surface.
As shown in fig. 2, the peak a of the cooling surface 31 is lower than the peak b of the outer blade 20, and the peak a of the cooling surface 31 is spaced from the upper end surface of the mounting bracket 10 by a distance h. So designed, make the cooling surface 31 higher relative to the position of the mounting bracket 10, this can guarantee that the cooling surface 31 of the metal heat dissipating part 30 can be prior to the upper end face contact skin of the mounting bracket 10, and, the cooling surface 31 of the metal heat dissipating part 30 is lower than the surface of the outer blade 20 again, so because there is certain float when using specifically outer blade 20, then it will keep as flush as possible with this cooling surface 31 when floating, so make the cooling surface 31 of the metal heat dissipating part 30 and outer blade 20 contact with skin more snugly.
Further, the metal heat-radiating member 30 is closed around the peripheral side of the outer blade 20. The outer blade 20 has a regular circular or rectangular structure, and the metal heat sink 30 is closely wound around the outer circumference of the outer blade 20 having the circular or rectangular structure, so that the cooling surface 31 of the metal heat sink 30 can be designed to have the largest area. That is, preferably, the metal heat-radiating member 30 is a closed ring-shaped structure having a shape similar to the peripheral shape of the outer blade 20.
Of course, the metal heat sink 30 may also be a non-closed loop structure. The metal heat dissipation members 30 having a non-closed loop structure may be formed in a strip structure, an arc structure or a dot structure with a spacing design.
In addition, the metal heat sink 30 includes an arc segment at least partially having an arc shape. The metal heat sink 30 may be formed by connecting a partial arc-shaped segment with a partial linear segment. The metal heat dissipation member 30 may be formed in a closed structure or a non-closed structure.
Of course, the metal heat sink 30 further includes a straight line segment at least partially linear.
Further, as shown in fig. 7, the upper end of the mounting bracket 10 is provided with a skin contact surface on the periphery of the outer blade 20, and the skin contact surface is a metal surface 13. Through the skin contact surface that sets up metallic structure at mounting bracket 10 upper end, can realize equally and skin contact and then the heat in the transmission skin, and then give off this heat, realize reducing the hotness degree on the skin. Which is combined with the metal heat radiating member 30 to achieve a better cooling effect.
The metal surface 13 may be the upper end surface of the entire mounting bracket 10, or may be a local position of the upper end surface of the mounting bracket 10.
Specifically, the mounting bracket 10 is made of a plastic material, a metal sheet is injection molded at the upper end of the mounting bracket 10, and the metal surface 13 is the upper end surface of the metal sheet. The metal sheet may be placed in a mold during injection molding of the mounting bracket 10 so as to be integrally fixed to the mounting bracket 10, and the metal sheet is exposed out of the mounting bracket 10, thereby forming the metal surface 13.
Of course, the entire mounting bracket 10 may be made of a metal material. In this way, the upper end surface of the mounting frame 10 is the metal surface 13, which can absorb and dissipate heat on the skin through contact with the skin, so as to effectively reduce the heat sensation on the skin.
In this embodiment, the mounting frame 10 and the metal sheet can be made of aluminum, iron or stainless steel.
