Description

Technical Field

[0001] The utility model relates to the technical field of components in an electric hair clipper, in particular to an elastic connecting seat and a cutter head accessory for an electric hair clipper. Background Art

[0002] As a commonly used hair care appliance, the cutter head part of an electric hair clipper generally includes a housing, a fixed cutter and a moving cutter mounted on the housing. To achieve the reciprocating cutting action of the moving cutter, a swing mechanism needs to be eccentrically connected to the moving cutter support for transmission. At the same time, in order to limit the movement path of the swing mechanism, a shaft also needs to be inserted so that it is limited to the movement direction of the moving cutter relative to the fixed cutter. Such a design inevitably makes the structure relatively bulky, there is energy consumption in the transmission between components, and the relative movement between transmission components is prone to generate heat due to friction, which is detrimental to its service life. At the same time, its assembly process is relatively complex. Especially to limit the movement trajectory of the moving cutter, during the installation process, the axis alignment of each shaft connection or socket structure needs to be corrected, and further sampling and correction are required after the assembly is completed, resulting in a relatively high production cost. Content of the Utility Model

[0003] In view of the above problems existing in the prior art, an elastic connecting seat and a cutter head accessory for an electric hair clipper are provided herein to overcome at least one of the above technical defects.

[0004] The specific technical solutions are as follows:

[0018] Preferably, the rear end of the moving knife bracket is further fixed by a fastener after being clamped with the clamping block structure through the clamping groove.

[0019] The beneficial effects of the above technical solutions are as follows:

[0029] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. And the following definitions are provided: Figure 2 The top-to-bottom direction shown on the paper is the back-to-front direction in this embodiment; the direction perpendicular to the paper and inwards is the top-to-bottom direction in this embodiment; and the left-to-right direction shown on the paper is the left-to-right direction in this embodiment.

[0030] Example 1,

[0031] See Figures 1 to 5 As shown in the illustration, the elastic connector provided in this embodiment is suitable for use in the blade attachment of electric clippers, for connecting the moving blade assembly of the blade attachment. The elastic connector includes:

[0032] Fixed base 5;

[0033] The elastic connecting frame 6 includes a crossbar 61 parallel to the fixed base 5 and located in front of the fixed base 5, and two spring sheet members 62 distributed on the left and right sides of the crossbar 61 and the fixed base 5, so as to allow the crossbar 61 to swing in the left and right direction relative to the fixed base 5 under the action of the two spring sheet members 62.

[0034] Furthermore, the crossbar 61 is used to connect the moving blade support 31 of the moving blade assembly 3, so that the moving blade support 31 can swing back and forth in the left and right directions.

[0035] Based on the above technical solution, the elastic connection seat includes a fixed seat 5 and an elastic connection frame 6. The elastic connection frame 6 includes a crossbar 61 and a spring plate member 62. The crossbar 61 is used to connect the moving knife support 31. The spring plate member 62 can swing in the left-right direction, enabling the moving knife support 31 to reciprocally swing in a preset direction. Without additional transmission and swinging mechanisms, the structure is more concise and easier to implement.

[0036] In a preferred embodiment, specifically as Figure 2 shown in, each spring plate member 62 is formed by stacking multiple long strip-shaped elastic sheets. On the one hand, it is restricted to only swing in the left-right direction, and on the other hand, it has better toughness and can meet the requirements of long-term reciprocating swinging. Further, each elastic sheet is made of stainless steel.

[0037] As a further embodiment, both the left and right sides of the crossbar 61 extend backward and are respectively connected to a spring plate member 62, resulting in an overall "冂" shape. Further, the crossbar 61 and the spring plate member 62 are of an integral structure.

[0038] As a further preferred embodiment, combined with Figure 1 shown in, the fixed seat 5 is in an overall frame-shaped structure, and the ends of the two spring plate members 62背离 the crossbar 61 are respectively connected to the left and right sides of the fixed seat 5 through fasteners, resulting in the elastic connection seat presenting an "口" shape in the top view.

[0039] In a preferred embodiment, combined with Figure 1 and Figure 5 shown in, a clamping groove 63 for clamping the moving knife support 31 is also formed on the crossbar 61. The moving knife support 31 has a clamping block structure 34 that matches the shape of the clamping groove 63. Further, the clamping groove 63 is configured with one side open, and the inner walls of the left and right sides form two relatively arranged transverse grooves 64. The left and right sides of the clamping block structure 34 respectively have a convex rib 35 that matches the shape of the transverse groove 64, so as to play a guiding and limiting role during assembly and make its installation structure more stable.

[0040] Embodiment Two,

[0041] Combined with Figure 6 It should be noted that there is an unclear expression "背离" in the original text. I translated it as "背离" for now. You may need to check and correct it according to the actual situation.As shown in the figure, the electric clipper head accessory provided in this embodiment includes a housing 1, a fixed blade assembly 2, a moving blade assembly 3, a magnetic drive assembly 4, and an elastic connecting seat as described in Embodiment 1, the elastic connecting seat is disposed inside the housing 1, the magnetic drive assembly 4 is at least partially limited and installed in the fixed seat 5, the moving blade bracket 31 of the moving blade assembly 3 is assembled and connected to the crossbar 61, and at least one magnetic element 33 is embedded at the rear end of the moving blade bracket 31, the front end of the magnetic drive assembly 4 is configured with a magnetic drive component facing the magnetic element 33, so that when the magnetic drive assembly 4 is in working state, it can cause the magnetic poles of the magnetic drive component to alternately change, and cause the moving blade assembly 3 and the elastic connecting frame to swing back and forth in the left and right direction synchronously.

[0042] This structural design allows the moving tool support 31 and the moving tool 32 to reciprocate without the need for an additional eccentric oscillating structure to transmit kinetic energy. This results in a higher energy conversion rate, a more streamlined and compact structure, and facilitates production assembly and maintenance. It also avoids the frictional heat generated by the reciprocating motion between transmission components, preventing wear and aging caused by long-term operation of components, and extending the product's service life.

[0043] Specifically, the fixed blade assembly 2 includes a fixed blade bracket hinged to the housing 1 and a fixed blade mounted on the fixed blade bracket. The moving blade assembly 3 includes a moving blade bracket 31, a moving blade 32 mounted on the moving blade bracket 31, and a magnetic element 33 embedded at the rear end of the moving blade bracket 31. The magnetic drive assembly 4 preferably consists of two electromagnets arranged side by side, with enameled copper wire wound on the two electromagnets in opposite directions. When an alternating current is input into the enameled copper wire, the front ends of the two electromagnets can form alternating magnetic poles with opposite polarities. Correspondingly, three magnetic elements 33 are selected and arranged side by side. The magnetic elements 33 are permanent magnets and are arranged with NSN poles or SNS poles. Alternatively, the magnetic drive assembly 4 can be configured as a single electromagnet and enameled copper wire wound on it, in which case there are two magnetic elements 33. It is not limited to this. The fixed blade bracket is also connected by an elastic element to keep the fixed blade adjacent to the moving blade 32.

[0044] In a preferred embodiment, the rear end of the moving blade support 31 is engaged with the locking block structure 34 via the locking groove 63 and then further secured with fasteners.

[0045] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
