[0002] A razor is a common personal care device in daily life. The shaving unit of a razor usually includes a supporting base, a blade net and a blade assembly, wherein the blade net and the blade assembly are fixed in the supporting base by a fixing structure, which makes it difficult for users to clean the beard inside the shaving unit, or inconvenient to replace the blade with a new one when the blade is worn. As a result, the razor makes loud noises or is not sharp when working, has a short battery life and poor shaving effect. Utility Model Content

DETAILED DESCRIPTION

[0024] Common personal care devices (such as razors and trimmers) typically include a head and a handle. The head consists of a cutter head assembly and a base. During daily cleaning, users separate the cutter head assembly from the base to clean the stubble on the cutter head assembly and the base. However, during cleaning, users discover that there are multiple shaving units inside the cutter head assembly's bracket. Each shaving unit contains a support seat, a blade net, and a blade assembly. The blade net and blade assembly are fixed to the support seat by a fixing structure, making them difficult to disassemble. This results in a large amount of stubble accumulating in the gap between the support seat, the blade net, and the blade assembly, making it difficult to clean. The blade assembly is prone to wear and tear after long-term use, resulting in blunt blades and poor shaving results.

[0025] To this end, the present application sets an easily detachable fixing frame on the supporting seat, and the fixing frame is easily deformed by squeezing, so that the fixing frame can be detachably connected to the supporting seat by utilizing the deformation characteristics of the fixing frame. Specifically, after the knife net and the blade assembly are installed on the supporting seat, the fixing frame is deformed by squeezing and installed at a preset position of the supporting seat, and when the squeezing force disappears, the fixing frame returns to its original shape and engages with the supporting seat, thereby fixing the knife net and the blade assembly on the supporting seat. At the same time, in order to facilitate squeezing the fixing frame again so that the fixing frame is deformed and detached from the supporting seat again, the present application also sets a force-applying operating part on the fixing frame, so that the user can apply force to the fixing frame through the operating part, so that the fixing frame is deformed and detached from the supporting seat, thereby facilitating disassembly and cleaning.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0027] like Figure 1 As shown, the present application provides a personal care device, which may include a base 2000 and a cutting head component 3000 detachably connected to the base 2000. The base 2000 may have a housing and a transmission element installed in the housing. The base 2000 is detachably connected to a handle, and the handle has an energy source and a driving element. The energy source is used to provide energy for the driving element to output power. The cutting head component 3000 includes a bracket 3100 and at least one shaving unit 1000. The shaving unit 1000 is installed on the bracket 3100, and the bracket 3100 is used to provide support for the shaving unit 1000. When the cutting head component 3000 is connected to the base 2000, the bracket 3100 is connected to the housing, and the driving element is connected to the shaving unit 1000 to drive the shaving unit 1000 to perform a shaving action.

[0028] In actual application, the number of shaving units 1000 can be one, two or three, etc. The personal care device can be a shaver, hair trimmer, etc. for shaving hair, or a hair ball trimmer for trimming hair balls, etc. This application does not make specific restrictions on this.

[0029] For the detailed structure of the shaving unit 1000, please refer to Figures 2 to 6In one feasible embodiment, the shaving unit 1000 may include at least a supporting base 100, a blade net 200, a blade assembly 300, and a fixing frame 400. The supporting base 100 serves as the main component of the shaving unit 1000 and is used to support and protect the other components of the shaving unit 1000. Specifically, the supporting base 100 has a receiving chamber 110, and an inlet 120 and an outlet 130 that are connected to the receiving chamber 110 and arranged opposite to each other. The receiving chamber 110 is used to accommodate the blade net 200, the blade assembly 300, and the fixing frame 400. The blade net 200 and the blade assembly 300 are sequentially arranged in the receiving chamber 110 through the inlet 120. The blade net 200 partially extends from the outlet 130, and the blade assembly 300 is at least partially located in the blade net 200.

[0030] In practical applications, the support base 100 is generally annular, and the blade net 200 can be cap-shaped. The diameter of the blade net 200 can be slightly smaller than the inner diameter of the accommodating chamber 110. During assembly, the blade net 200 can be placed into the accommodating chamber 110 through the inlet 120. Furthermore, the inner wall of the accommodating chamber 110 can be provided with a stepped portion, which protrudes inward from the inner wall of the accommodating chamber 110. When the blade net 200 is placed into the accommodating chamber 110, the stepped portion engages with the blade net 200, thereby preventing the blade net 200 from escaping from the outlet 130. After the blade net 200 and support base 100 are assembled, the blade assembly 300 can be placed into the blade net 200 through the inlet 120, with the cutting edge of the blade assembly 300 facing the blade net 200. During use, the blade net 200 provides a protective effect, while the rotating blade assembly 300 can cut hair, etc.

[0031] In this embodiment, the fixing frame 400 is used to confine the blade net 200 and the blade assembly 300 within the accommodating chamber 110. Specifically, the fixing frame 400 may include a first locking section 410, a second locking section 420, and two engaging sections 430. The first locking section 410 and the second locking section 420 are arranged opposite each other, and the two ends of the first locking section 410 are connected to the two ends of the second locking section 420 via the two engaging sections 430, thereby forming a cavity 440.

[0032] When the fixing frame 400 is mounted on the supporting base 100, the second buckle section 420 can be first inserted obliquely into one of the buckle grooves on the inner wall of the supporting base 100, and then the second buckle section 420 can be inserted obliquely into one of the buckle grooves on the inner wall of the supporting base 100. Figure 6The first buckle section 410 is pressed downward (in the vertical direction). At this time, the first buckle section 410 and the second buckle section 420 are squeezed and deformed inward. The cavity 440 provides deformation space for the first buckle section 410, the second buckle section 420 and the two engaging sections 430, thereby adaptively reducing the radial size of the fixing frame 400, facilitating the first buckle section 410 to snap into the other buckle slot, thereby achieving locking of the fixing frame 400 and completing the locking operation of the fixing frame 400 on the supporting base 100. When removing the fixing frame 400 from the supporting base 100, the first buckle section 410 can also be squeezed to cause the first buckle section 410 and the second buckle section 420 to squeeze and deform inward. This adaptively reduces the size of the fixing frame 400, facilitates the removal of the first buckle section 410 from the other buckle slot, thereby achieving locking contact of the fixing frame 400 and completing the removal operation of the fixing frame 400 from the supporting base 100. That is, during the assembly and disassembly process between the fixing frame 400 and the supporting base 100, the fixing frame 400 utilizes the cavity 440 to deform, causing the size of the fixing frame 400 to adaptively change through deformation, thereby allowing the first buckle section 410 and the second buckle section 420 to extend into or disengage from the corresponding buckle grooves located on the inner wall of the accommodating chamber 110. It should be noted that the direction of the "downward pressing" force defined in this application is not specifically limited to a vertically downward direction; the force can be applied as long as it has a downward vector component.

[0033] It is worth mentioning that, precisely through the aforementioned detachable connection between the fixing frame 400 and the supporting base 100, during assembly, the fixing frame 400 can deform so that the first and second buckling sections 410, 420 snap into place within their corresponding buckling slots. The buckling slots exert a limiting force on the fixing frame 400 along the axial direction of the supporting base 100, making it difficult for the fixing frame 400 to separate from the supporting base 100, thereby ensuring that the fixing frame 400 secures the blade net 200 and blade assembly 300. Furthermore, the cavity 440 allows the fixing frame 400 to adapt its dimensions to the deformation, thereby facilitating assembly and disassembly of the fixing frame 400. Furthermore, during disassembly, the user can easily remove the blade net 200, blade assembly 300, and fixing frame 400 from the supporting base 100 for cleaning, thereby facilitating the removal of hair from the shaving unit 1000.

[0034] The joint section 430 may be constructed in any shape, such as an arc shape, a wave shape, or a Z shape.

[0035] For example, if the connecting section 430 is configured as an arc, the connecting section 430 is recessed into the cavity 440, and a predetermined distance is left between the two connecting sections 430. Thus, when the first and second buckling sections 410, 420 are squeezed and deformed inward, the squeezing force from the first and second buckling sections 410, 420 can be transmitted to the two connecting sections 430, causing the two connecting sections 430 to also deform. This makes it easier for the size of the fixing frame 400 to adapt, further facilitating the assembly and disassembly of the fixing frame 400 and the supporting base 100.

[0036] like Figure 5 and Figure 6 As shown in FIG. 3 , in one possible embodiment, the blade assembly 300 includes a blade body 310 and a drive connecting shaft 320, and the drive connecting shaft 320 is connected to the blade body 310. Figure 6 From the perspective shown, when the fixing frame 400 is installed on the supporting seat 100, the first buckle section 410 and the second buckle section 420 are at least partially located directly above the knife net 200 to prevent the knife net 200 from moving upward, thereby cooperating with the above-mentioned step portion to stop the knife net 200 from being confined in the accommodating chamber 110; the two coupling sections 430 are at least partially located directly above the knife body portion 310 or directly above the step surface of the drive connecting shaft 320 to prevent the blade assembly 300 from moving upward, thereby cooperating with the knife net 200 to stop the blade assembly 300 from being confined in the knife net 200; and, the drive connecting shaft 320 passes between the two coupling sections 430 to prevent the two coupling sections 430 from interfering with the drive connecting shaft 320, thereby avoiding the coupling sections 430 from blocking the power transmission between the drive connecting shaft 320 and the drive element. In this way, the stopping and limiting of the knife net 200 and the blade assembly 300 can be achieved simultaneously through a fixing frame 400, thereby simplifying the connection and disassembly operations of the knife net 200 and the blade assembly 300.

[0037] For the sake of convenience, the above-mentioned buckle groove is specifically divided into a first buckle groove 111 and a second buckle groove 112 arranged relatively to each other. The first buckle groove 111 is used to snap-fit ​​with the first buckle section 410, and the second buckle groove 112 is used to snap-fit ​​with the second buckle section 420.

[0038] Regarding the specific structures of the first buckle section 410 and the second buckle section 420, as shown in FIG. Figure 5 、 Figure 7 and Figure 8As shown, in one feasible embodiment, the first buckle section 410 may include a first connecting arm 411 and a first buckle 412. The two ends of the first connecting arm 411 are respectively connected to one end of the two engaging sections 430. The first buckle 412 is provided on a side of the first connecting arm 411 away from the cavity 440. The first buckle 412 is configured to snap fit within the first buckle slot 111. During use, the deformation of the first connecting arm 411 can adaptively change the size of the fixing frame 400 so that both buckles snap into their corresponding buckle slots.

[0039] The second buckle section 420 may include a second connecting arm 421 and a second buckle 422. The two ends of the second connecting arm 421 are respectively connected to the other ends of the two engaging sections 430. The second buckle 422 is disposed on a side of the second connecting arm 421 away from the cavity 440. The second buckle 422 is configured to snap into engagement with the second buckle slot 112. During use, both the first connecting arm 411 and the second connecting arm 421 deform, causing the dimensions of the fixing frame 400 to adapt, improving the ease of deformation and further facilitating the engagement of both buckles into their corresponding buckle slots.

[0040] In practical applications, the first connecting arm 411 and the second connecting arm 421 can be configured in a C-shape, with the first buckle section 410 and the second buckle section 420 arranged in mirror-image symmetry with respect to the two engaging sections 430. The first buckle section 410, the second buckle section 420, and the two engaging sections 430 can be integrally formed using a method such as injection molding to ensure the structural stability of the fixing frame 400 and increase its service life.

[0041] In order to facilitate the insertion of the two buckles into the corresponding buckle slots, Figure 7 As shown, in one feasible embodiment, the first buckle 412 and / or the second buckle 422 are provided with a first inclined surface 450. The first inclined surface 450 is used to generate an inward force during the process of assembling the fixing frame 400 to the supporting base 100. It is understood that during the process of assembling the fixing frame 400 to the supporting base 100, the force applied by the user to the fixing frame 400 is in a downward direction. Under the action of the first inclined surface 450, this force can generate an inward force component, thereby squeezing the first buckle section 410, the second buckle section 420, and the two engaging sections 430 to cause deformation.

[0042] In this embodiment, when only the first buckle 412 has the first inclined surface 450, during assembly, the second buckle 422 can be first inserted obliquely into the second buckle slot 112, and then the first buckle 412 can be flipped downward with the second buckle 422 as a fulcrum, thereby cooperating with the first inclined surface 450, making it easier to snap the first buckle 412 into the first buckle slot 111. When only the second buckle 422 has the first inclined surface 450, during assembly, the first buckle 412 can be inserted obliquely into the first buckle slot 111, and then the second buckle 422 can be flipped downward with the first buckle 412 as a fulcrum, thereby cooperating with the first inclined surface 450, making it easier to snap the second buckle 422 into the second buckle slot 112. When both the first buckle 412 and the second buckle 422 have the first inclined surface 450, it is not necessary to distinguish which buckle is inserted into the buckle slot first. Alternatively, the fixing frame 400 can be pressed downward as a whole so that the first buckle 412 and the second buckle 422 are inserted into the corresponding buckle slots at the same time or almost at the same time.

[0043] In practical applications, the first inclined surface 450 refers to a surface with a certain slope, which can be an inclined surface or an inclined curved surface. The first inclined surface 450 is inclined toward the inner side of the fixing frame 400, so as to Figure 7 Taking the first inclined surface 450 on the first buckle 412 as an example, the first inclined surface 450 can be inclined substantially from the upper left to the lower right.

[0044] Regarding the specific formation method of the above-mentioned buckle groove, this application provides three feasible embodiments for reference.

[0045] Embodiment 1: A locking groove is formed on the inner wall surface of the supporting base 100, and the locking groove forms a buckling groove.

[0046] Example 2: Figure 4 As shown, the inner wall surface of the support base 100 can be provided with two sets of limit groups, which are arranged at intervals along the circumferential direction of the inner wall surface of the support base 100. Each set of limit groups includes a first limit block 140 and a second limit block 150, which are arranged at intervals along the axial direction of the support base 100, so that a locking groove can be formed between the first limit block 140 and the second limit block 150.

[0047] In practical applications, the first limiting block 140 and the second limiting block 150 can be integrally formed with the supporting base 100 to simplify the production process.

[0048] Embodiment 3: The buckling groove can be formed by the clamping groove opened on the inner wall surface of the above-mentioned supporting base 100 and the area between the first limiting block 140 and the second limiting block 150.

[0049] Taking the buckle groove formed in the manner described in the second and third embodiments as an example, the first limit block 140 can be provided adjacent to the inlet 120. A second inclined surface 141 is provided on a side of the first limit block 140 adjacent to the inlet 120. The second inclined surface 141 is inclined toward the inner side of the support seat 100. In this way, when assembling the fixing frame 400, the first inclined surface 450 of the fixing frame 400 can be in contact with the second inclined surface 141. Under the combined action of the first inclined surface 450 and the second inclined surface 141, the buckle can be more easily passed over the corresponding first limit block 140, thereby facilitating the assembly operation. The second inclined surface 141 also refers to a surface with a certain slope, which can be a bevel or an inclined curved surface. This is not specifically limited in this application.

[0050] In a feasible embodiment, a limiting groove may be provided on the knife net 200, and the knife net 200 may be assembled into the accommodating chamber 110 by cooperating with the limiting groove and the second limiting block 150, thereby preventing the knife net 200 from rotating under the action of the limiting groove and the second limiting block 150.

[0051] like Figure 7 and Figure 8 As shown, in one feasible embodiment, the fixing frame 400 may further include an operating portion 460, which is connected to the first buckle section 410 or the second buckle section 420, and at least a portion of the operating portion 460 extends from the area surrounded by the inner wall surface of the support base 100. In other words, when the fixing frame 400 is assembled on the support base 100, a portion of the fixing frame 400 still protrudes from the support base 100. In this way, when the fixing frame 400 is disassembled, the operating portion 460 can be used to squeeze the fixing frame 400, causing the fixing frame 400 to deform and thus detach from the support base 100.

[0052] In a feasible embodiment, a notch 160 is provided at one end of the support seat 100 adjacent to the entrance 120, and the operating portion 460 has a vertical rod section 461, one end of the vertical rod section 461 is connected to the first buckle section 410, and the other end of the vertical rod section 461 extends toward the entrance 120 and exceeds the bottom of the notch 160. In this way, the user squeezes the fixing frame 400 through the part of the vertical rod section 461 that exceeds the bottom of the notch 160 to facilitate the disassembly and assembly operations of the fixing frame 400.

[0053] In another alternative embodiment, a notch 160 is provided at one end of the support base 100 adjacent to the entrance 120. The operating portion 460 includes a vertical rod section 461 and a horizontal rod section 462. One end of the vertical rod section 461 is connected to the first buckle section 410, while the other end of the vertical rod section 461 extends toward the entrance 120 and connects to the horizontal rod section 462. The horizontal rod section 462 extends into the notch 160. In this way, the user can squeeze the fixing frame 400 through the horizontal rod section 462 to facilitate the installation and removal of the fixing frame 400.

[0054] In actual use, the crossbar section 462 may not extend beyond the side of the notch 160. Furthermore, the crossbar section 462 may not extend beyond the end surface of the support base 100 adjacent to the inlet 120, to prevent interference between the crossbar section 462 and the bracket 3100 and thereby affect the proper installation of the support base 100. The first buckle section 410, the second buckle section 420, the two engagement sections 430, and the operating portion 460 may be integrally formed to simplify the production process and reduce production costs.

[0055] For ease of understanding, Figure 9 As shown, the present application also provides a disassembly process of the fixing bracket 400 as follows:

[0056] First, the operating portion 460 is pushed in the direction indicated by the arrow on the operating portion 460. This transmits a force through the operating portion 460 to the first connecting arm 411, the second connecting arm 421, and the two engaging segments 430, causing the first connecting arm 411, the second connecting arm 421, and the two engaging segments 430 to deform. As the first connecting arm 411, the second connecting arm 421, and the two engaging segments 430 deform, the distance between the first buckle 412 and the second buckle 422 decreases, causing the first buckle 412 to disengage from the first buckle slot 111.

[0057] Then, the fixing frame 400 is turned upward with the second buckle 422 as a fulcrum through the operating portion 460 , so that the first buckling section 410 and the two engaging sections 430 are separated from the accommodating chamber 110 .

[0058] Finally, the fixing frame 400 is taken out along an inclined direction, and the disassembly operation of the fixing frame 400 is completed.
