Description

Technical Field

[0001] This application relates to the field of razor technology, and in particular to a razor head that is easy to fix. Background Technology

[0002] An electric shaver is a cosmetic appliance that uses electricity to drive blades to shave and trim beards and sideburns. According to the movement of the blades, it can be divided into two types: rotary and reciprocating. The working principle of a reciprocating shaver is that the motor drives the eccentric wheel to rotate, causing the output shaft of the eccentric wheel to move back and forth in a certain direction, which drives the moving blade to move relative to the fixed blade screen, cutting the beard that extends into the fixed blade screen.

[0003] In reciprocating shavers, the shaver head is typically fixed inside the outer casing and then inside the mounting base. However, in actual use, the shaver head is often not securely fixed to the mounting base, resulting in poor shaving performance and potentially causing skin irritation due to head movement. To address this issue, a shaver head design that facilitates secure fixing has been proposed, aiming to improve shaving comfort and safety. Utility Model Content

[0004] To facilitate the fixing of the shaver head, a shaver head that is easy to fix is ​​provided.

[0005] The above-mentioned objective of this application is achieved through the following technical solution:

[0006] A shaver head that is easy to fix includes a shaver head assembly and a mounting base located below the shaver head assembly. Both ends of the shaver head assembly are equipped with connecting components. Each connecting component includes a snap-fit ​​member, one end of which is fixedly connected to the shaver head assembly, and the other end of which is vertically downward. Both ends of the mounting base have slots that fit into the snap-fit ​​members. At least one limiting member is installed on the inner wall of the slot. The limiting member includes an elastic protrusion, and the elastic protrusion engages with the end of the snap-fit ​​member that is inserted into the slot.

[0007] By adopting the above technical solution, the snap-fit ​​component is inserted into the slot, and the elastic protrusion limits the snap-fit ​​component, restricting it to remain in the slot and preventing it from popping out in the opposite direction of insertion. This makes the connection between the shaver head assembly and the shaver head mounting base tighter, reduces the gap between the shaver head assembly and the mounting base, and avoids shaver head shaking or wobbling caused by the gap. This improves the stability of the shaver during shaving and prevents shaking or abnormal noise caused by loose shaver head.

[0008] Optionally, the plane of the snap-fit ​​member that abuts against the elastic protrusion in the direction of insertion into the card slot is set as a guide surface, and the guide surface is inclined from the bottom of the card slot toward both sides of the card slot.

[0009] By adopting the above technical solution, a guiding role is played when installing the snap-fit ​​component. When the user inserts the snap-fit ​​component into the slot of the mounting base, it can slide into the slot more easily through the elastic protrusion, reducing the difficulty of the installation process and allowing the snap-fit ​​component to be inserted into the slot more smoothly.

[0010] Optionally, the plane in contact with the elastic protrusion and the snap-fit ​​member is set as the contact surface, and the contact surface is inclined from top to bottom towards the outside of the slot.

[0011] By adopting the above technical solution, when the user aligns the snap-fit ​​component of the cutter head assembly with the slot on the mounting base, the inclined elastic protrusion can play a guiding role, guiding the snap-fit ​​component to enter the slot more easily, reducing the probability of the snap-fit ​​component being misaligned or stuck with the slot during installation, and making the whole installation process smoother.

[0012] Optionally, the cutter head assembly has a limit hole on the side facing the mounting base, and a limit post is installed on the side of the mounting base facing the cutter head assembly, with the upper end of the limit post extending into the limit hole, and a support spring in the extended state is provided on the outer sleeve of the limit post.

[0013] By adopting the above technical solution, when the shaving head assembly is shaving, the shaving head assembly is compressed by pressure to support the spring. The support spring stores elastic potential energy and bounces the shaving head assembly upward. The support spring provides elastic support in the extended state, effectively absorbing the vibration and impact during shaving, ensuring a more thorough shave and improving the shaving effect.

[0014] Optionally, the mounting base has a movable groove communicating with the card slot. A rotating shaft perpendicular to the insertion direction of the card is installed in the movable groove. A limiting protrusion is installed in the movable groove, with one end of the limiting protrusion movably sleeved on the rotating shaft and the other end extending outside the movable groove. A torsion spring is sleeved on the rotating shaft, with one end of the torsion spring abutting against the limiting protrusion in the opposite direction of the insertion direction of the card, and the other end of the torsion spring abutting against the inner wall of the movable groove.

[0015] By adopting the above technical solution, when it is necessary to disassemble the shaver head assembly for cleaning or replacement, the user only needs to apply a force in the direction opposite to the insertion of the retaining piece into the slot to smoothly remove the shaver head assembly from the mounting base without encountering excessive resistance or obstacles. The limiting protrusion can easily disengage from the retaining piece under the action of the pivot and torsion spring, making the disassembly process simpler and faster, and facilitating the user to perform regular maintenance and upkeep of the shaver.

[0016] Optionally, the end of the limiting protrusion located outside the movable groove is chamfered.

[0017] By adopting the above technical solution, when the snap-fit ​​component moves along the insertion slot direction, the guide surface of the snap-fit ​​component will contact the limiting protrusion. Therefore, a chamfer is added to the end of the limiting protrusion, which can further reduce the friction between the guide surface and the limiting protrusion, ensuring that the snap-fit ​​component can slide past the limiting protrusion and snap into the slot.

[0018] Optionally, it also includes a housing, on which a slider is installed along the direction of insertion into the slot of the snap-fit ​​component, and a groove is opened inside the housing for the slider to fit into, and the slider slides within the groove.

[0019] By adopting the above technical solution, when the housing needs to be installed on the mounting base, the sliding connection between the slide groove and the slider plays a guiding role, which facilitates the positioning of the housing and improves the installation efficiency of the housing.

[0020] Optionally, at least one limiting block is fixed on the inner wall of the housing, and at least one limiting groove is opened on the mounting base, with the limiting block engaging with the limiting groove.

[0021] By adopting the above technical solution, the limiting block on the inner wall of the outer shell and the limiting groove on the mounting base cooperate with each other to provide precise positioning for the outer shell and enhance the fixing effect of the outer shell.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. The snap-fit ​​component engages with the elastic protrusion in the slot. The elastic protrusion limits the snap-fit ​​component, making the connection between the cutter head assembly and the cutter head mounting base tighter, reducing the gap between the cutter head assembly and the mounting base, and avoiding cutter head shaking or wobbling caused by the gap.

[0024] 2. When it is necessary to disassemble the cutter head assembly for cleaning or replacement, the user only needs to apply a force in the direction opposite to the insertion of the snap-fit ​​component into the slot. The snap-fit ​​component will press against the limiting protrusion and rotate it in the circumferential direction of the rotating shaft, thereby causing the limiting protrusion to rotate into the movable groove, making it easy to remove the cutter head assembly from the mounting base.

[0032] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0033] Example 1

[0034] As attached Figure 1 As shown, a shaver head that is easy to fix includes a housing 1, a mounting base 3, and a connecting component 4.

[0035] The cutter head assembly 2 is located above the mounting base 3. The cutter head assembly 2 includes a side mounting bracket 21 and a middle mounting bracket 22. There are two side mounting brackets 21. The two side mounting brackets 21 are parallel to the middle mounting bracket 22 and are located on both sides of the middle mounting bracket 22.

[0036] As attached Figure 2 As shown, six limiting posts 32 are installed on the side of the mounting base 3 facing the blade assembly 2. Limiting holes 23 are opened at both ends of the side mounting bracket 21 and the middle mounting bracket 22 facing the mounting base 3. The upper ends of the limiting posts 32 are inserted into the limiting holes 23 respectively. The outer periphery of each limiting post 32 is fitted with a support spring 33 in the extended state. One end of the support spring 33 abuts against the mounting base 3, and the other end is located in the limiting hole 23. When shaving, the blade assembly 2 is subjected to pressure and compresses the support spring 33. The support spring 33 stores elastic potential energy and bounces the blade assembly 2 upward. The support spring 33 provides elastic support in the extended state, effectively absorbing the vibration and impact during shaving, and ensuring a more thorough shave.

[0037] As attached Figure 3As shown, three slots 31 are opened on both ends of the mounting base 3. Two slots 31 that are parallel to each other at both ends are set as a group, and the three groups of slots 31 are located on the same horizontal plane as the two side mounting brackets 21 and the middle mounting bracket 22. Limiting members 5 are fixed on the inner wall of the slots 31. The limiting members 5 include elastic protrusions 51. There are two elastic protrusions 51. The two elastic protrusions 51 are parallel to each other. Both elastic protrusions 51 are located at the upper end of the slots 31. The elastic protrusions 51 are made of elastic material. A contact surface 511 is provided on the side of the elastic protrusion 51 that faces away from the bottom of the slots 31. The contact surface 511 is inclined from top to bottom towards the outside of the slots 31.

[0038] There are six connecting components 4, which are located at both ends of the two side mounting brackets 21 and both ends of the middle mounting bracket 22. Each connecting component 4 includes a snap-fit ​​member 41, which is perpendicular to the mounting base 3. One end of the snap-fit ​​member 41 is fixedly connected to the side of the cutter head assembly 2 facing the mounting base 3, and the other end is vertically inserted into the slot 31. The snap-fit ​​member 41 has an abutment surface 412 on the side facing away from the bottom of the slot 31. The abutment surface 412 engages with two elastic protrusions 51. The two elastic protrusions 51 limit the snap-fit ​​member 41, restricting it from being located in the slot 31 and preventing it from popping out of the direction from which it was inserted into the slot 31.

[0039] The plane of the snap-fit ​​41 that abuts against the elastic protrusion 51 in the direction of insertion into the slot 31 is set as a guide surface 411, and the guide surface 411 is inclined from the bottom of the slot 31 toward both sides of the slot 31. It plays a guiding role when installing the snap-fit ​​41. When the user inserts the snap-fit ​​41 into the slot 31 of the mounting base 3, it can slide into the slot 31 more easily through the elastic protrusion 51, reducing the difficulty of the installation process and allowing the snap-fit ​​41 to be inserted into the slot 31 more smoothly.

[0040] As attached Figure 1 As shown, the sidewalls at both ends of the outer shell 1 have an arc-shaped cross-section. The outer shell 1 is located on the outer periphery of the mounting base 3. Two limiting blocks 12 are installed on the inner walls on both sides of the outer shell 1. Two limiting grooves 34 are opened on the outer walls on both sides of the mounting base 3. The limiting blocks 12 and the limiting grooves 34 are matched and engaged one-to-one. When the outer shell 1 needs to be installed on the mounting base 3, the limiting blocks 12 on the inner wall of the outer shell 1 and the limiting grooves 34 on the mounting base 3 cooperate with each other to provide precise positioning for the outer shell 1, which facilitates the limiting of the position of the outer shell 1 and improves the installation efficiency of the outer shell 1.

[0041] The connecting component 4 also includes sliders 42, the number of which is equal to the number of snap-fit ​​pieces 41. The sliders 42 are fixedly connected to the snap-fit ​​pieces 41, and the sliders 42 are perpendicular to the mounting base 3. Three sliding grooves 11 are installed on the inner walls of both ends of the housing 1. The sliders 42 at both ends of the cutter head assembly 2 are slidably connected to the sliding grooves 11 at both ends of the housing 1. The sliding connection between the sliding grooves 11 and the sliders 42 serves as a guide, facilitating the installation of the housing 1 on the mounting base 3.

[0042] The advantage of this embodiment is that:

[0043] The snap-fit ​​component 41 engages with the elastic protrusion 51 in the slot 31. The elastic protrusion 51 limits the snap-fit ​​component 41, making the connection between the cutter head assembly 2 and the cutter head mounting base 3 tighter, reducing the gap between the cutter head assembly 2 and the mounting base 3, and preventing the cutter head assembly 2 from shaking or swaying due to the gap.

[0044] Example 2

[0045] As attached Figure 4 and attached Figure 5 As shown, this second embodiment is an improvement on the first embodiment, and the other structures are the same as those in the first embodiment, so they will not be described in detail here.

[0046] The mounting base 3 has a movable groove 35 that communicates with the slot 31. A rotating shaft 36 perpendicular to the insertion direction of the snap-fit ​​member 41 is installed in the movable groove 35. The limiting member 5 also includes a limiting protrusion 52, which is located in the movable groove 35. One end of the limiting protrusion 52 is movably sleeved on the rotating shaft 36, and the other end extends out of the movable groove 35. The end is chamfered. When the snap-fit ​​member 41 moves along the insertion direction of the slot 31, the guide surface 411 of the snap-fit ​​member 41 will contact the limiting protrusion 52. Therefore, the end of the limiting protrusion 52 is chamfered to further reduce the friction between the guide surface 411 and the limiting protrusion 52, ensuring that the snap-fit ​​member 41 can slide past the limiting protrusion 52 and snap into the slot 31.

[0047] A torsion spring 37 is sleeved on the rotating shaft 36. One end of the torsion spring 37 abuts against the limiting protrusion 52 in the opposite direction of the insertion of the locking member 41, and the other end of the torsion spring 37 abuts against the inner wall of the movable groove 35. The elastic force of the torsion spring 37 is greater than the elastic force of the supporting spring 33. When it is necessary to disassemble the cutter head assembly 2 for cleaning or replacement, the user only needs to apply a force in the opposite direction of the insertion of the locking member 41 into the slot 31 to easily remove the cutter head assembly 2 from the mounting base 3, which facilitates the disassembly of the cutter head assembly 2.

[0048] The advantage of this embodiment is that:

[0049] When it is necessary to disassemble the cutter head assembly 2 for cleaning or replacement, the user only needs to apply a force in the direction opposite to the insertion of the snap fastener 41 into the slot 31. The snap fastener 41 will press against the limiting protrusion 52 and rotate it in the circumferential direction of the rotating shaft 36, thereby causing the limiting protrusion 52 to rotate into the movable slot 35, making it easy to disassemble the cutter head assembly 2 from the mounting base 3.

[0050] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of protection claimed in this application.
