[0034] The embodiment provides a shaver, in particular a shaver capable of lifting and massaging a face, which comprises a driving device 1 and a head device 2, the driving device 1 is provided with a driving shell 11 arranged outside, and the driving shell 11 is internally provided with a driving module for driving the head device 2 to work and a power module for supplying power to the driving module. The head device 2 is detachably installed on the driving device 1 and works under the driving of the driving device 1.

[0035] As shown in Figure 1 , the head device 2 is provided with a head base 21, at least one blade group 3 and a lifting roller 4, the head base 21 is detachably installed on the driving device 1, and a head cover 23 matched with the driving shell 11 is arranged outside the head base 21, the blade group 3 is movably arranged on the head base 21, and the lifting roller 4 is installed on the blade group 3. As shown in Figure 2 , the lifting roller 4 is provided with a roller body 40 and a roller mounting end 43, the roller body 40 is provided with at least two protrusions 41 distributed along the axial direction, and the adjacent two protrusions 41 are connected through a concave part 42; the roller mounting end 43 is located at both ends of the roller body 40 along the length direction, and is used for mounting the roller body 40 on the blade group 3. When the lifting roller rolls on the skin, the skin is lifted under the action of the protrusions 41 and the concave part 42.

[0036] In the embodiment, as shown in Figure 2 (a), the protrusions 41 are two, the concave part 42 is one, and the concave part 42 is located between the adjacent two protrusions 41. Each protrusion 41 is provided with a pressing section 411 located at the middle part and used for pressing the skin and lifting sections 412 located at both sides of the pressing section 411 and used for extruding the face skin, and the lifting sections 412 on the opposite sides of the connected two protrusions 41 are connected in a smooth transition to form the concave part 42. The diameters of the lifting sections 412 on both sides of the pressing section 411 decrease with the increase of the distance from the pressing section 411. When rolling in contact with the skin, the pressing section 411 pushes and presses the skin inward, and the skin on both sides is pushed to the lifting sections 412, so that the skin is pulled tight. The whole protrusion 41 is a spindle-shaped rotary body structure with the outer diameter gradually decreasing from the middle part to both sides. The protrusion 41 with such a structure has a smooth surface, and the pressing section 411 and the lifting sections 412 have no clear boundary line. When in contact with the skin, on the one hand, the skin can be more easily stretched in a smooth manner, so that the skin in contact with the protrusion 41 is recessed and stretched to both sides, and the skin in contact with the concave part 42 is extruded, thereby realizing the massage effect of lifting and tightening the skin; on the other hand, the friction can be reduced, and the shaver can be more easily matched with the blade group.

[0037] In actual situations, as shown in Figure 2As shown in (b) of FIG. 4, the protrusions 41 can also be provided in three, and the corresponding recesses 42 are provided in two. The protrusions 41 can form the recesses 42 between the two protrusions 41 only when the protrusions 41 are provided in at least two. When the two protrusions 41 are in contact with the skin, the skin on both sides of the protrusions 41 can be squeezed and pushed towards the middle, so that the skin at the position of the recesses 42 can also be pulled tight.

[0038] In another embodiment, the abutting section 411 and the pulling section 412 can have a clear boundary, and the cross-sectional outer contour shape of the abutting section 411 can be an outward convex arc or a straight line parallel to the axis or other shapes, mainly to roll on the skin surface to reduce the friction of the shaver; the cross-sectional outer contour shape of the pulling section 412 can be one or more of an inclined straight line, an outward convex arc, and an inward concave arc, mainly to pull the skin; the recess 42 can be directly formed by the pulling sections 412 on the opposite sides of the two protrusions 41, or the recess 42 can be formed by the pulling sections 412 on the opposite sides of the two protrusions 41 and the transition section between the two pulling sections 412, i.e. the transition section is located at the bottom of the recess 42, and the cross-sectional outer contour shape of the transition section can also be one or more of a horizontal straight line, an outward convex arc, an inward concave arc, and a wavy shape.

[0039] The cutter group 3 has a static cutter assembly and a dynamic cutter assembly. The static cutter assembly includes a static cutter holder 31 and a static cutter blade 32 fixedly arranged on the static cutter holder 31, and the dynamic cutter assembly includes a dynamic cutter seat 33 and a dynamic cutter blade 34 fixedly arranged on the dynamic cutter seat 33 and movably arranged inside the static cutter blade 32. The static cutter holder 31 is movably arranged on the cutter head base 21 (specifically, the static cutter holder 31 can move in the height direction relative to the cutter head base 21), and the dynamic cutter blade 34 is movably arranged inside the static cutter blade 32 and can reciprocate along the length direction of the dynamic cutter blade 34 relative to the static cutter blade 32. In use, the static cutter blade 32 is in contact with the skin and moves along the skin under the driving of the user's hand, and can also float up and down along the height direction of the cutter head base 21 together with the static cutter holder 31; the dynamic cutter blade 34 mainly serves to cut and moves up and down along the height direction inside the static cutter blade 32 together with the static cutter blade 32, and the dynamic cutter blade 34 and the static cutter blade 32 almost keep in close contact, and the dynamic cutter blade 34 can cut the beard in cooperation with the static cutter blade 32 when reciprocating along the length direction of the dynamic cutter blade 34.

[0040] In the embodiment, the roller mounting end 43 of the pulling roller 4 is mounted on the static blade holder 31 and located at one side of the static blade 32, so that the pulling roller 4 can move along the height direction together with the static blade 32. Specifically, when the cutter group 3 contacts with the protruding parts on the skin such as the mandible and Adam's apple, the cutter group 3 moves along the height direction of the cutter head base 21, and the pulling roller 4 moves along the height direction of the cutter head base 21 in coordination with the movement of the cutter group 3. The pulling roller 4 is mounted on the cutter head base 21 through the static blade holder 31, and the static blade holder 31 has a pair of guide portions 310 oppositely arranged in the length direction, the pair of guide portions 310 protrude to form protruding parts towards the same side, and a roller mounting hole 311 for inserting the two roller mounting ends 43 is arranged on the opposite side of the pair of protruding parts, and the roller mounting end 43 is columnar and is inserted into the roller mounting hole 311 on both sides during installation. That is, the pulling roller 4 is directly mounted on the static blade holder 31, without the need to additionally arrange a connecting structure, which simplifies the structure, saves costs, and makes the structure more compact and simple, and is easy to install, which is beneficial to the light weight and miniaturization of the electric shaver. A protruding ring 44 protruding from the roller mounting end 43 is arranged between the roller body 40 and the roller mounting end 43, which can form positioning and limiting when the roller mounting end 43 cooperates with the roller mounting hole 311, and can also enhance the stability of the structure installation. In addition, the protruding ring 44 and the adjacent pulling section 414 are connected through a recess, which can further improve the pulling and massaging effect.

[0041] When the cutter group 3 has one, the pulling roller 4 can be installed on the front side of the cutter group 3 or on the rear side of the cutter group 3. Since the pulling roller 4 is mounted on the static blade holder 31, the pulling roller 4 can always follow the cutter group 3 to float. When the pulling roller 4 is installed on the front side or the rear side of the cutter group 3, it can be installed on the static blade holder 31 of the cutter group 3 or on the cutter head base 21 located on the front side or the rear side of the cutter group 3. In comparison, the installation on the static blade holder 31 is better, which can make the pulling roller 4 float together with the static blade holder 31.

[0042] When the cutter group 3 has two, the two cutter groups 3 are respectively a first cutter group 3a located on the front side and a second cutter group 3b located on the rear side, and the roller mounting end 43 can be mounted on the static blade holder 31 of the first cutter group 3a or the second cutter group 3b, for example, the roller mounting end 43 can be mounted on the front side of the static blade holder 31 of the first cutter group 3a; the roller mounting end 43 can be mounted on the rear side of the static blade holder 31 of the first cutter group 3a (i.e. the front side of the static blade holder 31 of the second cutter group 3b), or on the rear side of the static blade holder 31 of the second cutter group 3b. As Figure 5As shown, the roller mounting end 43 is installed on the front side of the stationary blade holder 31 of the second blade assembly 3b. The guide portion 310 of the stationary blade holder 31 of the second blade assembly 3b protrudes forward to form a roller mounting hole 311. Then, the roller mounting end 43 is inserted into the roller mounting hole 311 to achieve installation. The lifting roller 4 floats along with the stationary blade holder 31 of the blade assembly 3 to which it is mounted.

[0043] When the lifting roller 4 is positioned between the first blade assembly 3a and the second blade assembly 3b, during operation, when encountering protruding parts on the skin, the first blade assembly 3a floats along the skin first, followed by the lifting roller 4 and the second blade assembly 3b. At this time, the rotation of the lifting roller 4 is less obstructed, and a transition is formed between the first and second blade assemblies 3a and 3b, allowing for smoother movement of the blade assembly on the skin. Furthermore, when the first blade assembly 3a contacts the skin, the lifting roller 4 subsequently contacts the skin as well. The lifting roller 4 reduces friction between the blade assembly and the skin, allowing the electric shaver's head assembly 2 to move even more smoothly on the skin.

[0044] Furthermore, when the lifting roller 4 is located between the first blade group 3a and the second blade group 3b, the highest point of the protrusion 41 is higher than the highest point of the stationary blade 32 of the first blade group 3a, and the lifting roller 4 is mounted on the stationary blade holder 31 of the second blade group 3b. In use, the lifting roller 4 can form a smoother connection between the first blade group 3a and the second blade group 3b.

[0045] like Figures 6-8 As shown, the stationary tool holder 31 can be floated along the height direction on the tool head base 21. The specific installation structure between the two is as follows: the guide part 310 of the stationary tool holder 31 is located on the outer side of the tool head base 21 and forms a vertically arranged guide bar 3101. The outer side of the tool head base 21 is correspondingly provided with a guide groove 211. The bottom of the guide groove 211 is provided with a blocking edge 2111 for blocking the bottom end of the guide bar 3101. The guide bar 3101 is inserted into the guide groove 211 from top to bottom, and when the guide bar 3101 is inserted into the guide groove 211, the guide bar 3101 is suspended in the guide groove 211. When the bar 3101 moves to its lower end and abuts against the blocking edge 2111, the guide part 310 moves to its lowest position. A limit stop 3102 is formed inside the cutter head base 21 by the guide part 310. A limit stop edge 212 is provided inside the cutter head base 21 corresponding to the limit stop 3102. The limit stop 3102 is located below the limit stop edge 212, which limits the travel of the guide part 310. When the two contact, the guide part 310 moves to its highest position. A guide spring 36 is also provided between the guide part 310 and the cutter head base 21. One end of the guide spring 36 abuts against the cutter head base 21, and the other end abuts against the guide part 310, supporting and resetting the guide part 310. Under the action of the guide spring 36, the cutter assembly can float along the cutter head base 21 in the height direction as the user moves.
