Description

Technical Field

[0001] The utility model relates to the technical field of hair care equipment, in particular to a vibration reduction component applied to hair care equipment. Background Art

[0002] As the popularity of hair care equipment increases, the types of related care appliances are endless and varied, such as: hair clippers, razors and hair clippers.

[0003] However, hair care equipment generates strong omnidirectional vibrations when working, which can easily cause the following problems:

[0004] 1. When the operator is holding the hair care device, the vibration is obvious, which not only greatly affects the user experience, but also has an adverse effect on the haircut effect when the operator is a barber and needs to ensure a certain operating accuracy;

[0005] Second, vibration will produce a lot of noise. When performing haircutting operations, the user being haircut often needs to endure this harsh noise. When performing pet hair care, this noise will also make the pets restless, making it difficult to perform normal hair care on them.

[0006] Therefore, how to solve the above-mentioned deficiencies in the prior art has become a topic to be studied and solved in the present invention. Utility Model Content

[0007] The utility model aims to provide a vibration reduction component applied to hair care equipment.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A vibration reduction assembly for hair care equipment, the vibration reduction assembly includes a shaft wheel and a counterweight slider. The shaft wheel includes a shaft seat, a driving member and a lever, the shaft wheel rotates around the length direction center line; from a top view, the lever and the driving member are eccentrically arranged on two opposite sides of the center line. The lever is fixed on the top of the shaft seat and is connected to a moving cutter head; the driving member is fixed on the shaft seat and is relatively arranged below the lever. The bottom of the shaft seat passes through a positioning seat and is assembled with the output shaft of a motor. The counterweight slider has a Y-direction length hole for passing the shaft wheel. The shaft wheel is passed through the Y-direction length hole, the width of the driving member corresponds to the width of the Y-direction length hole, the outer side surface of the driving member abuts against the hole wall of the Y-direction length hole, and the rotation of the shaft wheel drives the counterweight slider and the positioning seat to slide in the X direction.

[0010] In the above scheme, the lever and the driving member are eccentrically arranged on two opposite sides of the center line. With this design, when the equipment is working, the movement direction of the counterweight slider acted by the driving member is opposite to the movement direction of the moving cutter head acted by the lever, thereby offsetting the quick return vibration generated by the cutter head part, thereby effectively reducing the vibration.

[0011] A further technical solution is that the vibration damping assembly is installed inside the machine head, and the machine head is also connected to a handle, the handle has a body shell that defines the interior, and the motor and the corresponding power supply assembly are arranged in the body shell, a tool holder is provided at the front end of the body shell, and a moving tool head and a stationary tool head that is fitted with the moving tool head are provided on the tool holder.

[0012] In a further technical solution, a knife seat is provided on the movable cutter head and a pressure piece that cooperates with the shaft wheel is provided on the knife seat. A pivot is also provided on the movable cutter head. A spring piece that can rotate with the pivot and abut against the bottom of the movable cutter head is sleeved on the pivot. The spring piece is provided on the positioning seat and is a torsion spring or an S-shaped elastic piece with a certain bending angle. Cutting teeth are provided on both the stationary cutter head and the movable cutter head, and the movable cutter head slides back and forth laterally relative to the stationary cutter head through a retaining spring to overcome the rotational force. The retaining spring is fixed to the inside of the machine head through a spring frame. The cutting teeth cooperate with each other to perform hair care operations, and the hair repair cutting is achieved through the staggered sliding movement between the cutting teeth.

[0013] According to a further technical solution, the counterweight slider includes a counterweight block and a sliding base plate, wherein the counterweight block and the sliding base plate can be an integrated structure, and a dust cover can be provided between the counterweight block and the sliding base plate, and the dust cover and the sliding base plate can be an integrated structure.

[0014] A further technical solution is that the sliding base plate is arranged below the counterweight block, and a contact hole for passing the shaft wheel member is provided at the center of the counterweight block, and the contact hole has a length in the Y direction (in this case, the contact hole is a hole with a length in the Y direction), and a sliding frame is provided at the center of the sliding base plate corresponding to the contact hole, and the sliding frame has a through hole matching the shape of the contact hole. When the sliding base plate and the counterweight block are assembled, the sliding frame is located in the contact hole, and the two are matched and combined (in this case, the through hole is the contact hole); the outer side surface of the driving member is abutted against the inner side surface of the sliding frame through the rotation of the shaft wheel member, so that the sliding base plate and the positioning seat are slidably matched in the X direction (that is, the counterweight slider and the positioning seat are slidably matched in the X direction).

[0015] In a further technical solution, a cutting portion is provided on the cylindrical shaft seat for maintaining the mass balance between the shaft seat and the lever. The cutting portion reduces the mass of the shaft seat so that the mass of the shaft seat and the lever are the same, thereby achieving a dynamic balance between the two and improving the overall rotational stability of the shaft wheel component.

[0016] Further technical solution: The side surface of the driving member is a polygonal structure, and the polygonal structure has at least three sides. The polygonal structure includes a non-equilateral polygonal structure and an equilateral polygonal structure. Preferably, the formula for the inscribed regular n-sided polygon of a circle is: A = nr 2 sin(360° / n) / 2, where A is the area and n is the number of sides; when n approaches ∞, the regular n-sided polygon will approach a circle infinitely. By setting the polygonal structure to more than 50 sides, the outer wall is infinitely close to a circle, so the wall thickness difference in the circumferential direction is small, and the transmission force efficiency of the driving member can be improved better.

[0017] Further technical solution: The counterweight block includes a pair of clamping grooves that penetrate the counterweight block in the up and down directions. The two clamping grooves are symmetrically arranged at the left and right ends of the abutting hole. The sliding bottom plate is provided with a pair of clamping blocks corresponding to the clamping grooves. The counterweight block is assembled above the sliding bottom plate, and the counterweight block is relatively fixed to the sliding bottom plate.

[0018] The present utility model further includes a limiting member acting between the counterweight slider and the positioning seat. A downward limiting pressure is applied to the counterweight slider through the limiting member to prevent the counterweight slider from jumping up and down, and ensure that the counterweight slider fits on the positioning seat. The first end of the limiting member is positioned on the counterweight block, and the second end of the limiting member is positioned on the inner side wall of the fuselage shell.

[0019] Specifically, the limiting member includes a first torsion spring arm, an elastic bending portion, a torsion spring and a second torsion spring arm. Two torsion springs that are integrally wound and concentrically arranged, and the two torsion springs have opposite winding directions, and the second torsion spring arms extending from the same side of the two are connected. The second torsion spring arm forms a "U"-shaped bracket structure. The opposite sides of the two torsion springs are respectively connected with deformable elastic bending portions, and are connected to the second torsion spring arm for clamping through the corresponding elastic bending portions. So that the elastic pressing member is an elastic semi-surrounding structure for pressing and limiting the counterweight slider to prevent the counterweight slider from jumping up and down.

DETAILED DESCRIPTION

[0052] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0053] Embodiment: The present invention will be clearly described below with diagrams and detailed descriptions. After understanding the embodiments of the present invention, any person skilled in the art can make changes and modifications based on the techniques taught by the present invention without departing from the spirit and scope of the present invention.

[0054] The terms used herein are only for describing specific embodiments and are not intended to be limiting of the present invention. Singular forms such as "a", "this", "here", "this" and "the" as used herein also include plural forms.

[0055] Example 1

[0056] See attached Figure 1-13As shown, the vibration reduction assembly is installed inside the head A of a hair clipper, and the head A is also connected to a handle B. The handle B has a body shell C that defines the interior, and a motor 13 and a corresponding power supply assembly that are arranged in the body shell C. A tool holder 4 is arranged at the front end of the body shell C, and a moving cutter head 2 and a stationary cutter head 1 that are arranged in close contact with the moving cutter head 2 are arranged on the tool holder 4. The moving cutter head 2 is provided with a tool seat, and a pressing plate 3 that cooperates with the shaft wheel member 7 is provided on the tool seat. The moving cutter head 2 is also provided with a pivot, and a spring piece 111 that can rotate with the pivot and abut against the bottom of the moving cutter head 2 is sleeved on the pivot. The spring piece 111 is arranged on the positioning seat 11 (as shown in FIG. Figure 3 As shown, the positioning seat 11 at this time can be a spring seat), and the spring 111 is a torsion spring or an S-shaped elastic sheet with a certain bending angle. Cutting teeth are provided on both the stationary cutter head 1 and the movable cutter head 2, so that the movable cutter head 2 can slide back and forth horizontally relative to the stationary cutter head 1 through the retaining spring 5 to overcome the rotational force. The retaining spring 5 is fixed inside the machine head A through a spring frame 6, which is convenient for disassembly and replacement of the retaining spring 5.

[0057] The vibration reduction assembly includes a shaft wheel component 7 and a counterweight slider 8. The shaft wheel component 7 includes a shaft seat 71, a driving component 72 and a lever 74. The lever 74 is eccentrically fixed on the top of the shaft seat 71 and is drivingly connected to the movable cutter head 2. The driving component 72 is eccentrically fixed on the shaft seat 71 and relatively arranged below the lever 74. The bottom of the shaft seat 71 passes through the positioning seat 11 and is transmission-assembled with the output shaft 12 of the motor 13.

[0058] The counterweight slider 8 includes a counterweight block 81 and a sliding bottom plate 82. The counterweight block 81 is assembled on the top of the sliding bottom plate 82. The center of the counterweight block 81 is provided with an abutment hole 811 for passing the shaft wheel member 7. The center of the sliding bottom plate 82 is provided with a slide frame 821 corresponding to the abutment hole 811. In the assembled state, the slide frame 821 is located in the abutment hole 811, and the two are adapted to be combined, wherein the counterweight block 81 includes a pair of positioning grooves 812 that penetrate the counterweight block 81 in the up-down direction, and the two positioning grooves 812 are symmetrically arranged at the left and right ends of the abutment hole 811; the sliding bottom plate 82 is provided with a pair of positioning blocks 62 corresponding to the positioning grooves 812; the counterweight block 81 is assembled on the top of the sliding bottom plate 82, and the counterweight block 81 and the sliding bottom plate 82 are relatively fixed.

[0059] The limiting member 9 between the counterweight slider 8 and the positioning seat 11 includes a first torsion spring arm 91, an elastic bending portion 92, a torsion spring 93, and a second torsion spring arm 94; two torsion springs 93 that are integrally wound and concentrically arranged, with opposite winding directions, and the second torsion spring arms 94 extending from the same side of the two torsion springs 93 are connected, and the second torsion spring arms 94 form a "U"-shaped bracket structure; the opposite sides of the two torsion springs 93 are respectively connected with deformable elastic bending portions 92, and are connected to the second torsion spring arms 94 for positioning through the corresponding elastic bending portions 92; so that the elastic pressing member 9 is an elastic semi-surrounding structure, thereby realizing that the limiting member 9 presses and limits the counterweight slider 8 relative to the positioning seat 11.

[0060] The shaft wheel member 7 sequentially passes through the abutting hole 811 of the counterweight block 81, the sliding frame of the sliding bottom plate 82, and the positioning seat 11, and is传动装配 (transmissively assembled) with the output end of the motor 13 through the转接孔75 (adapter hole 75) opened at the bottom end of the shaft wheel member 7. When the hair clipper is started, the motor 13 generates mechanical rotation through the power supply assembly, thereby driving the output shaft 12 to transmit power to the shaft wheel member 7. When the shaft wheel member 7 continuously rotates, the outer side surface of the driving member 72 abuts and cooperates with the inner side surface of the abutting hole 811 through the rotation of the shaft wheel member 7, thereby driving the counterweight block 81 to drive the sliding bottom plate 82 to reciprocally slide along the X direction (such as Figure 7a 、 7b as well as shown in 7c), and its movement direction is opposite to the movement direction of the moving cutter head 2 of the hair clipper, thereby offsetting the unstable regular vibration and irregular vibration generated by the hair clipper, and further substantially offsetting all unstable vibrations.

[0061] Thus, the lever 74 drives the moving cutter head 2 to reciprocally slide horizontally relative to the stationary cutter head 1 through the pressing piece 3, and the cutting teeth between the moving cutter head 2 and the stationary cutter head 1 cooperate to perform hair removal operations, and high-efficiency hair repair is achieved through the staggered sliding movement between the cutting teeth. During this process, after comprehensive vibration reduction treatment in the vertical and horizontal directions, hair can be repaired more comprehensively and efficiently, ensuring the cleaning effect of the hair care device.

[0062] Embodiment 2

[0063] See Appendix Figure 1 and Appendix Figure 14-15 As shown, the vibration reduction assembly includes a homogeneous shaft wheel member 7a (the shaft wheel member 7 is a homogeneous shaft wheel member 7a) and a first counterweight slider 8a. Among them, several weight reduction holes 14 are opened on the driving member 72 of the homogeneous shaft wheel member 7a, so that the mass of the homogeneous shaft wheel member 7a is equal, which helps to improve the rotational stability.

[0064] The first counterweight slider 8a is a cube structure, and a first abutting hole 813 is opened at the central part of the first counterweight slider 8a, and the first abutting hole 813 has a length in the Y direction.

[0065] The first positioning seat 11a is a groove structure with two ends opened in the X direction. The first positioning seat 11a has a limiting function on the first counterweight slider 8a in the up and down directions. The first counterweight slider 8a is slidably assembled in the first positioning seat 11a along the X direction.

[0066] The isotropic shaft wheel 7a passes through the first abutment hole 813, the first positioning seat 11a and the output end transmission assembly of the motor 13 in sequence. When the hair clipper is started, the motor 13 generates mechanical rotation through the power supply component, thereby driving the output shaft 12 to transmit power to the isotropic shaft wheel 7a. When the isotropic shaft wheel 7a continues to rotate, the isotropic shaft wheel 7a and the inner wall of the first abutment hole 813 perform inscribed motion, thereby driving the first counterweight slider 8a on the first positioning seat 11a along the X direction (such as Fig.14 The movable blade head 2 of the hair clipper is moved back and forth on the hair clipper, and its movement direction is opposite to that of the movable blade head 2 of the hair clipper, thereby offsetting the unstable regular vibration and irregular vibration generated by the hair clipper, and then substantially offsetting all unstable vibrations. Therefore, the lever 74 is used to drive the movable blade head 2 to slide back and forth relative to the stationary blade head 1 through the pressing plate 3, and the interlaced sliding movement between the cutting teeth of the movable blade head 2 and the stationary blade head 1 realizes hair trimming.

[0067] Example 3

[0068] See attached Figure 1 and attached Figure 16-17 As shown, the vibration reduction assembly includes an isotropic shaft wheel component 7a (the shaft wheel component 7 is an isotropic shaft wheel component 7a) and a second counterweight slider 8b.

[0069] The second counterweight slider 8b is a cubic structure, and a second abutment hole 814 is opened at the center of the second counterweight slider 8b. The second abutment hole 814 has a length in the Y direction, and the second counterweight slider 8b has two symmetrical through-holes 15 opened along its length direction.

[0070] The second positioning seat 11b is a "U"-shaped structure composed of two vertical plates and a horizontal plate. The second counterweight sliding block 8b can be placed in the second positioning seat 11b.

[0071] It also includes two guide rods 16, both of which are arranged with their length direction corresponding to the X direction, and pass through the corresponding through-holes 15 to slide and assemble the second counterweight slider 8b on the two vertical plates of the second positioning seat 11b. The isotropic wheel 7a passes through the second abutment hole 814 and the second positioning seat 11b in sequence, and is assembled with the output end of the motor 13; when the hair clipper is started, the motor 13 generates mechanical rotation through the power supply component, thereby driving the output shaft 12 to transmit power to the isotropic wheel 7a. When the isotropic wheel 7a continues to rotate, the isotropic wheel 7a and the inner wall of the second abutment hole 814 perform inward movement, thereby driving the second counterweight slider 8b on the second positioning seat 11b along the X direction (such as Fig.16The movable blade head 2 of the hair clipper is moved back and forth on the hair clipper, and its movement direction is opposite to that of the movable blade head 2 of the hair clipper, thereby offsetting the unstable regular vibration and irregular vibration generated by the hair clipper, and then substantially offsetting all unstable vibrations. Therefore, the lever 74 is used to drive the movable blade head 2 to slide back and forth relative to the stationary blade head 1 through the pressing plate 3, and the interlaced sliding movement between the cutting teeth of the movable blade head 2 and the stationary blade head 1 realizes hair trimming.

[0072] Example 4

[0073] See attached Figure 1 and attached Figure 18-19 As shown, the vibration reduction assembly includes an isotropic shaft wheel member 7a (the shaft wheel member 7 is an isotropic shaft wheel member 7a) and a third counterweight slider 8c;

[0074] The third counterweight slider 8c is a cubic structure, and a third abutment hole 815 is provided at the center of the third counterweight slider 8c. The third abutment hole 815 has a length in the Y direction, and guide grooves 17 are provided on the fourth edges of the third counterweight slider 8c along its thickness direction, and the length direction of the guide grooves 17 corresponds to the X direction. Four positioning pins 18 pass through the corresponding guide grooves 17 to slide the third counterweight slider 8c onto the third positioning seat 11c of the plate-like structure.

[0075] The isotropic shaft wheel 7a passes through the third abutment hole 815, the third positioning seat 11c and the output end transmission assembly of the motor 13 in sequence. When the hair clipper is started, the motor 13 generates mechanical rotation through the power supply component, thereby driving the output shaft 12 to transmit power to the isotropic shaft wheel 7a. When the isotropic shaft wheel 7a continues to rotate, the isotropic shaft wheel 7a and the inner wall of the third abutment hole 815 perform inscribed motion, thereby driving the third counterweight slider 8c on the third positioning seat 11c along the X direction (such as Fig.18 The movable blade head 2 of the hair clipper is moved back and forth on the hair clipper, and its movement direction is opposite to that of the movable blade head 2 of the hair clipper, thereby offsetting the unstable regular vibration and irregular vibration generated by the hair clipper, and then substantially offsetting all unstable vibrations. Therefore, the lever 74 is used to drive the movable blade head 2 to slide back and forth relative to the stationary blade head 1 through the pressing plate 3, and the interlaced sliding movement between the cutting teeth of the movable blade head 2 and the stationary blade head 1 realizes hair trimming.

[0076] Example 5

[0077] See attached Figure 1 and attached Figure 20-21 As shown, the vibration reduction assembly includes an isotropic shaft wheel member 7a (the shaft wheel member 7 is an isotropic shaft wheel member 7a) and a fourth counterweight slider 8d;

[0078] The fourth counterweight slider 8d is a square structure, and a fourth abutment hole 816 is opened in the central part of the fourth counterweight slider 8d. The fourth abutment hole 816 has a length in the Y direction. Based on the vertical center line of the fourth abutment hole 816, two countersunk holes are symmetrically opened on the fourth counterweight slider 8d, that is, the connecting line of the two countersunk holes is the X direction.

[0079] The fourth positioning seat 11d is composed of two offset parallel horizontal plates connected to a vertical vertical plate. A connecting groove 112 is provided at the center of the upper horizontal plate, and a protrusion 113 is provided on the outer side of the vertical plate.

[0080] After the fourth counterweight slider 8d is slidably assembled on the fourth positioning seat 11d, the two bayonet openings of the torsion spring member 19 are correspondingly located in the two countersunk holes, and the two torsion spring coils are placed on the horizontal plate above the fourth positioning seat 11d. The adjacent axial direction between the two torsion spring coils extends to form a curved hook portion, which passes through the connecting groove 112 and is hooked on the protrusion 113. The fourth counterweight slider 8d is reciprocated along the X direction by the action of the torsion spring member 19.

[0081] The isotropic wheel 7a passes through the fourth abutment hole 816, the fourth positioning seat 11d and the output end transmission assembly of the motor 13 in sequence, wherein the rotational power of the isotropic wheel 7a can overcome the elastic force of the torsion spring 19, thereby effectively limiting the vertical jumping of the fourth counterweight slider 8d. When the hair clipper is started, the motor 13 generates mechanical rotation through the power supply component, thereby driving the output shaft 12 to transmit power to the isotropic wheel 7a. When the isotropic wheel 7a continues to rotate, the isotropic wheel 7a and the inner wall of the fourth abutment hole 816 perform inscribed motion, thereby driving the fourth counterweight slider 8d on the fourth positioning seat 11d along the X direction (such as Fig. 20 The movable blade head 2 of the hair clipper is moved back and forth on the hair clipper, and its movement direction is opposite to that of the movable blade head 2 of the hair clipper, thereby offsetting the unstable regular vibration and irregular vibration generated by the hair clipper, and then substantially offsetting all unstable vibrations. Therefore, the lever 74 is used to drive the movable blade head 2 to slide back and forth relative to the stationary blade head 1 through the pressing plate 3, and the interlaced sliding movement between the cutting teeth of the movable blade head 2 and the stationary blade head 1 realizes hair trimming.

[0082] It can be seen that the vibration reduction component is suitable for any hair care device that needs vibration reduction.
