DETAILED DESCRIPTION

[0048] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0049] The core of the present application is to provide a decompressible rotary shaver, which has entertainment and reduces the space occupation in the shell.

[0050] In the specific embodiment one of the decompressible rotary shaver provided by the present application, please refer to Figures 1 to 6 , which comprises a rotating body and at least one support 9 arranged outside the rotating body.

[0051] The rotating body comprises a shell 2 and a protective cover 1 which are detachably connected along a first direction X. The shell 2 is provided with a head assembly 4 at the opening facing the protective cover 1, and the protective cover 1 covers the opening. When shaving, the protective cover 1 is removed, and after shaving, the head assembly 4 can be covered by the protective cover 1.

[0052] The outer surface of the casing 2 is rotatably connected to the support 9. Specifically, the support comprises a rotating bearing 91 connected to the outer surface of the casing 2 and a support body 913 connected to the rotating bearing 91, that is, the rotating bearing 91 is connected between the outer surface of the casing 2 and the support body 913 to enable the rotation of the rotating body relative to the support body 913, so that the rotating body can specifically rotate 360° relative to the support body 913.

[0053] As shown in Figure 3 and Figure 5 , the casing 2 is rotatably connected to the support 9 on two opposite outer surfaces in the second direction Y, and the casing 2 can be independently rotatable relative to each support 9. For example, in the present embodiment, the support 9 is a first support 95, and in the first support 95, the support body 913 is a support disc 94, which can specifically be a disc.

[0054] In addition, the number of supports 9 can be one, two, three or more, and the user can hold two supports 9 at the same time to push the rotating body to rotate with the two supports 9 as fulcrums. When there is only one support 9, refer to Figure 13 the embodiment, the support 9 is a circular ring, which can provide multiple fulcrums to push the rotating body to rotate, or when the support 9 is a disc structure, refer to Figure 7 the embodiment, the shape of the support 9 can also push the rotating body to rotate horizontally by pushing up or pushing down the support 9, which does not affect the realization of the rotating function.

[0055] The above-described decompression rotary shaver (referred to as shaver) combines the use function and the rotating function. The protective cover 1 is opened, the basic shaving function is realized by means of the head assembly 4, and since each support disc 94 in each support 9 is rotatably connected to the outer side of the casing 2 through the rotating bearing 91, and each support disc 94 can independently rotate clockwise or counterclockwise, when the user holds the support disc 94 to shave, the shaver can rotate and tilt according to the angle of different parts of the face, chin and neck, etc., so that the shaver can be rotated according to the face shape, and the use is more convenient. Moreover, such external design and separate connection of the support disc 94 can ensure the integrity of the casing 2, improve the structural strength of the casing 2, reduce or avoid the design of the joint, increase the impact resistance of the casing 2, improve the sealing, waterproof and dustproof performance, in addition, the rotatable connection of the support 9 to the outer surface of the casing 2 can also reduce the occupation of the internal space of the casing 2, and improve the flexibility of the arrangement of components in the internal space of the casing 2. When the shaving function is not used, the rotating body of the shaver can be rotated by hand or by supporting the support with a support frame, to ensure the entertainment and decompression function of the shaver.

[0056] Further, the shaver further comprises a head motor 6, which is built in the inner cavity of the casing 2 and is drivingly connected to the head assembly 4, so as to electrically drive the head assembly 4 and form the electric shaver.

[0057] In order to save cost, as shown in Figure 2 and Figure 3 , only one head motor 6 is arranged. Compared with the embodiment in which multiple head motors 6 are arranged, the material cost is lower, the production process is simpler, and the process personnel required is less, so that the shaver is more cost-effective in the market. Of course, in other embodiments, two or other numbers of head motors 6 can also be arranged.

[0058] In terms of mounting the head motor 6, as shown in Figure 2 , the head motor 6 is centrally arranged in the inner cavity of the housing 21 in the third direction Z. Since the weight of the head motor 6 accounts for a large proportion of the entire shaver in the shaver, at this time, the head motor 6 is centrally arranged, so that the center of gravity of the shaver is centralized, the balance and stability of the shaver are greatly improved, and the user is more labor-saving when holding the support disc 94 to shave, and the shaving operation is more convenient. Of course, in other embodiments, the head motor 6 can also be arranged at the edge in the third direction Z, or can also be centrally arranged in the first direction X and the second direction Y.

[0059] In the inner cavity of the casing 2, the remaining space on both sides of the head motor 6 in the third direction Z is applied, and devices with the same weight or a small weight difference can be placed on both sides, so as to further ensure that the center of gravity of the shaver is centralized. For example, an energy module, specifically a battery, is arranged on the first side of the head motor 6, and a battery or a bracket or other device is arranged on the second side, and the weight of the battery on the first side is the same as that on the second side. The energy module supplies power to drive the movement of the moving blade relative to the static blade of one or more head assemblies to shave the beard.

[0060] In addition, as shown in Figure 3 , in the second direction Y, the head motor 6 is in abutment with the inner wall of the inner cavity of the casing 2, so as to position the head motor 6 in the second direction Y by means of the casing 2.

[0061] It should be noted that in the description of the embodiments of the present application, the first direction X, the second direction Y and the third direction Z are three different directions, for example, two are perpendicular. For example, Figure 2 and Figure 3 , the shaver in the embodiment is convenient for the user to pinch the two support discs 94 from both sides of the shaver, and the second direction Y corresponds to the thickness direction, and the size thereof is smaller than the size of the shaver in the first direction X and the third direction Z. As shown in Figure 1As shown, to facilitate the rotation of the razor for shaving or as a fidget spinner, the cross-sectional shape of the razor perpendicular to the second direction Y can be circular. The diameter corresponding to both the first direction X and the second direction Y is the same. Furthermore, the rotation center line of the support disk 94 passes through the center of this circular cross-section and is parallel to the second direction Y. Of course, in other embodiments, the cross-sectional shape can also be rectangular, triangular, etc.

[0062] Furthermore, a battery 7 is also provided inside the housing 2 to power the electrical components of the shaver. One battery 7 can be selected as needed, or at least two batteries 7, such as two or three. Additionally, the shaver head motor 6 and other electrical components can be electrically connected to some or all of the batteries 7 as needed.

[0063] like Figure 2 As shown, in this embodiment, there are two batteries 7, namely a first battery 71 and a second battery 72 located on both sides of the blade motor 6 in the third direction Z. The first battery 71 and / or the second battery 72 are electrically connected to the blade motor 6. At this time, the first battery 71 and the second battery 72 can provide sufficient power to the blade motor 6 to ensure the battery life. The two batteries 7 distributed on both sides of the blade motor 6 can ensure the centrality of the shaver's center of gravity. Of course, in other embodiments, such as... Figure 8 As shown, battery 7 can also be set to only one.

[0064] To enable charging of battery 7, the housing 2 is provided with a charging connector 8 that is electrically connected to battery 7, which is exposed on the housing 2 for connection to a charger.

[0065] like Figure 2 As shown, on the third direction Z, a charging connector 8 is provided on the side of the housing 2 near the second battery 72. The first battery 71 and the second battery 72 are electrically connected to the charging connector 8 for charging the first battery 71 and the second battery 72. Specifically, the charging connector 8 includes a charging tail plug 82 and a tail plug waterproof ring 81 provided in the charging hole on the housing 2, with the tail plug waterproof ring 81 covering the outside of the charging tail plug 82.

[0066] To achieve on / off control of the shaver, such as Figure 2 As shown, on the third direction Z, a switch button 5 is provided on the side of the housing 2 near the first battery 71. The switch button 5 is electrically connected to the first battery 71 and the second battery 72. At this time, the switch button 5 and the support plate 94 are mounted on the surfaces of the housing 2 in different directions, which can improve the utilization rate of the surface of the housing 2 and prevent accidental activation of the switch button 5 when the support plate 94 rotates relative to the housing 2.

[0067] Specifically, such as Figure 2As shown, the key hole is formed on the shell 2, and the switch key 5 is connected to the key hole and sealed to the key hole through the switch waterproof ring 52 and the waterproof pressing plate 53.

[0068] Specifically, as shown in Figure 2 the first battery 71 and the switch key 5 in the third direction Z, and the switch key 5 is electrically connected to the first battery 71 and the second battery 72 through the circuit board 51, realizing switch control.

[0069] Of course, in other embodiments, the switch key 5 and the charging connector 8 can also be arranged in other positions. For example Figure 8 As shown, the switch key 5 is arranged on one side of the shell 2 in the third direction Z, and the charging connector 8 is arranged at the end of the shell 2 away from the protective cover 1 in the first direction X; or, the switch key 5 can also be arranged on one side of the shell 2 in the second direction Y.

[0070] Further, the cutter head motor 6 is connected to the cutter head assembly 4 through the reciprocating transmission assembly to form a reciprocating shaver. As shown in Figure 2 and Figure 3 The reciprocating transmission assembly includes an eccentric wheel 62, a first driving sub 63, a transmission sub 64, a second driving sub 65 and a third driving sub 66. The first driving sub 63 is connected to the output shaft of the cutter head motor 6 through the eccentric wheel 62, the second driving sub 65 is connected to the first driving sub 63 through the transmission sub 64, and the third driving sub 66 is fixedly connected to the first driving sub 63. Such transmission assembly structure is compact, and the reciprocating movement of the cutter head is realized through the transmission cooperation between the single cutter head motor 6 and the driving sub.

[0071] Specifically, in the transmission process, as shown in Figure 2 and Figure 3 The eccentric wheel 62 is fixed to the output shaft of the cutter head motor 6, the eccentric end of the eccentric wheel 62 is inserted into the sliding groove of the first driving sub 63, the sliding groove extends along the second direction Y, and under the driving of the cutter head motor 6, the eccentric wheel 62 moves along a circular track, pushes the sliding groove to drive the first driving sub 63 to move linearly along the third direction Z. The first driving sub 63 drives the second driving sub 65 to move reciprocally along the third direction Z through the transmission sub 64, and drives the third driving sub 66 to move reciprocally along the third direction Z. The first driving sub 63, the second driving sub 65 and the third driving sub 66 respectively drive the cutter heads to move reciprocally along the third direction Z.

[0072] Specifically, in the arrangement of the driving sub, as shown in Figure 3As shown, in the second direction Y, the third drive unit 66 is located between the first drive unit 63 and the second drive unit 65; the cutter head includes a blade cutter head 42 connected to the third drive unit 66 and two mesh cutter heads 43 respectively connected to each of the first drive unit 63 and the second drive unit 65.

[0073] Furthermore, in the structural design of the cutter head assembly 4, a reciprocating transmission assembly is incorporated, such as... Figure 2 and Figure 3 As shown, the cutter head assembly 4 specifically includes an outer blade holder 45, a cutter head seat 41, a mesh cutter head 43, and a blade cutter head 42.

[0074] Among them, such as Figure 2 , Figure 3 and Figure 5 As shown, the outer blade holder 45 is fixed to the opening of the housing 2 facing the protective cover 1, and is specifically detachably connected to the housing 2, for example, by snap-fit ​​connection or magnetic connection. The outer blade holder 45 has a cutting edge that extends through the first direction X, and the blade head seat 41 is fixed to the outer blade holder 45. The mesh blade head 43 and the slice blade head 42 are both provided on the blade head seat 41, and the mesh blade head 43 and the slice blade head 42 extend through the cutting edge of the outer blade holder 45. At this time, part of the blade head assembly 4 can be installed and removed from the housing 2 together with the outer blade holder 45.

[0075] Furthermore, in the structure of casing 2, such as Figure 2 As shown, it includes an outer shell 21, an inner shell 22, and an internal support 23.

[0076] The inner shell 22 and the internal support 23 are fixed within the outer shell 21. In the first direction X, the internal support 23 is fastened to the end of the inner shell 22 near the protective cover 1, specifically through a snap-fit ​​mechanism. The interior of the inner shell 22 forms the inner cavity of the housing 2; more specifically, the inner cavity is located between the internal support 23 and the inner shell 22. During assembly, the inner shell 22 and the internal support 23 can be sequentially assembled onto the outer shell 21. The fit between the inner shell 22 and the outer shell 21 ensures the structural strength of the housing 2.

[0077] Specifically, to improve the waterproof performance of the inner cavity of casing 2, such as Figure 2 and Figure 3 As shown, a waterproof ring 24 is also provided at the joint of the internal support 23 and the inner shell 22.

[0078] Specifically, to achieve the installation of the support plate 94 outside the casing 2, such as Figure 3As shown, the two side plates of the outer shell 21 in the second direction Y are respectively provided with mounting holes 211, and the two outer sides of the inner shell 22 in the second direction Y are respectively provided with bottom grooves 221, that is, the bottom grooves 221 are blind hole structures. Each bottom groove 221 corresponds to one end of each mounting hole 211 in the second direction Y to form a mounting groove 212. Each mounting groove 212 is respectively provided with a rotating bearing 91, and a support disc 94 is connected to the corresponding rotating bearing 91. Specifically, the outer ring of the rotating bearing 91 is fixed to the mounting groove 212, and the inner ring is fixedly connected to the support disc 94.

[0079] At this time, through the provision of the mounting hole 211, sufficient space is provided for the installation of the rotating bearing 91, and the rotating bearing 91 connects the chassis 2 and the support disc 94, ensuring the smoothness of the relative rotation of the support disc 94 and the chassis 2. Of course, in other embodiments, only blind hole type bearing mounting holes can be provided on the outer shell 2.

[0080] In addition, the chassis 2 also includes a decorative ring 25. As shown in Figure 3 , Figure 5 and Figure 6 , the outer shell 21 is further provided with a side groove communicating with the mounting hole 211 on the outer surface in the second direction Y to provide processing space and facilitate the installation of the rotating bearing 91, and two decorative rings 25 are respectively covered on the two sides of the outer shell 21 in the second direction Y and correspondingly cover the side groove. As shown in Figure 3 , part of the rotating bearing 91 can extend into the center through hole of the decorative ring 25 to connect the support disc 94, and the support disc 94 includes a disc body 92 and a center column 93, the disc body 92 covers the center through hole of the decorative ring 25, and the center column 93 is connected to the rotating bearing 91.

[0081] Specifically, to realize the assembly of the chassis 2 and the components in the inner cavity, as shown in Figure 2 , the inner support 23 is integrally provided with a positioning rack, and the positioning rack extends into the inner shell 22 to install and position the tool bit motor 6 and the battery 7.
