Detailed Implementation

[0044] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0045] This utility model discloses a side-damped adjustable cutter head mechanism for electric clippers and an electric clipper. By engaging a toothed cutter head scale block with a toothed end-mounted cutter head adjustment handle, rotating the cutter head adjustment handle forces the cutter head scale block and the cutter head adjustment handle to reciprocate relative to each other, and a crisp collision sound is generated by a spring, thereby realizing a level feedback adjustment method. This can provide users with a clearer adjustment signal, and fewer parts are used, effectively controlling production costs.

[0046] According to the side-damped adjustable cutter head mechanism for electric clippers provided by this utility model, such as Figure 1-3 As shown, it includes a moving blade assembly, a lower blade 10, a tension spring 4, a blade head sliding block 5, a blade head fixing frame 6, a blade head adjusting handle 9, a blade head pitch spring 7, and a blade head pitch block 8; the moving blade assembly is installed at the front of the blade head fixing frame 6, the blade head sliding block 5 is installed in the blade head fixing frame slot 62 in the middle of the blade head fixing frame 6, and can slide in the front and back direction, the lower blade 10 is fixedly installed at the bottom of the blade head fixing frame 6, and is located below the moving blade assembly. Specifically, the lower blade 10 is fixedly installed at the bottom of the blade head fixing frame 6 by a lower blade screw 11;

[0047] The tension spring 4 is fixedly installed in the cutter head sliding block 5. The tension spring seat hook 43 of the tension spring 4 abuts against the top of the moving blade assembly and is fixed to apply pressure toward the lower blade 10. The cutter head adjusting handle 9 is inserted into the rear of the cutter head fixing frame 6 from the side. The cutter head pitch block 8 is engaged and fixed to the rear of the cutter head fixing frame 6 and is configured to be able to move along the axial direction of the cutter head adjusting handle 9 but not rotate around the axial direction of the cutter head adjusting handle 9. One end of the cutter head pitch block 8 has a pitch block wave plate 81, which engages with the adjusting handle wave plate 92 at the end of the cutter head adjusting handle 9. The other end of the cutter head pitch block 8 abuts against the inner wall of the cutter head fixing frame 6 through the cutter head pitch spring 7. The middle of the cutter head adjusting handle 9 is provided with an adjusting handle slot 91 for engaging with the rear end of the cutter head sliding block 5 and for driving the cutter head sliding block 5 to move back and forth in the cutter head fixing frame slot 62. Specifically, the rocker arm of the cutter head adjusting handle 9 is located on the side of the cutter head fixing frame 6.

[0048] The working principle of this utility model is as follows: When the blade head adjusting handle 9 is rotated, the adjusting handle slot 91 in the middle drives the blade head sliding block 5 to move back and forth in the blade head fixing bracket slot 62, thereby realizing the adjustment of the tooth spacing between the upper blade 1 and the lower blade 10. At this time, the adjusting handle wave plate 92 at the end of the adjusting handle 9 rotates synchronously. Since the blade head pitch block 8 is configured to be non-rotatable, the adjusting handle wave plate 92 and the pitch block wave plate 81, which were originally meshed with each other, will gradually rotate to a state where the tooth tips abut against each other. After further rotation, the two mesh again, and a crisp collision sound is generated by the blade head pitch spring 7, thereby completing the gear shift.

[0049] In a preferred example, such as Figure 4 As shown, the moving blade assembly includes an upper blade 1, an oil storage felt 2, and a blade guide block 3; the upper blade 1, the oil storage felt 2, and the blade guide block 3 are fixedly connected in sequence from bottom to top, and the top of the blade guide block 3 passes through the blade fixing frame 6 and is used to connect the machine body eccentric shaft. Specifically, the upper blade 1, the oil storage felt 2, and the blade guide block 3 can be fixed together through positioning pin holes.

[0050] In a preferred example, such as Figure 4 As shown, the top of the cutter guide block 3 is provided with a cutter guide block spring hole 31, and the tension spring seat hook 43 is fixed in the cutter guide block spring hole 31, so that when the cutter slide block 5 slides back and forth, the force is transmitted to the cutter guide block 3 to realize the adjustment of the tooth pitch.

[0051] In a preferred example, such as Figures 5-9 As shown, the bottom of the cutter head sliding block 5 is provided with a sliding block spring coil fixing groove 51 and a sliding block spring support rod fixing groove 52; the tension spring coil 41 of the tension spring 4 is accommodated in the sliding block spring coil fixing groove 51, and the tension spring support rod 42 of the tension spring 4 is inserted into the sliding block spring support rod fixing groove 52 and abuts against the side wall of the sliding block spring support rod fixing groove 52. The tension spring coil 41 and the tension spring support rod 42 are both fixed in the cutter head sliding block 5, and the tension spring seat hook 43 is in a compressed state to provide pressure.

[0052] Specifically, the assembly steps between the tension spring 4, the cutter head sliding block 5, and the cutter head fixing frame 6 are as follows: fix the tension spring coil 41 of the tension spring 4 in the sliding block spring coil fixing groove 51 of the cutter head sliding block 5, and at the same time fix the tension spring support rod 42 of the tension spring 4 in the sliding block spring support rod fixing groove 52 of the cutter head sliding block 5, and install the assembly of the tension spring 4 and the cutter head sliding block 5 into the cutter head fixing frame slot 62 of the cutter head fixing frame 6.

[0053] In a preferred embodiment, the adjusting handle slot 91 is a circular slot, and its axis is parallel to the axis of the adjusting handle 9. The rear end of the cutter head sliding block 5 is provided with a sliding block connecting cylinder 53 corresponding to the adjusting handle slot 91. The sliding block connecting cylinder 53 is engaged in the adjusting handle slot 91 and is rotatably fitted with it. When adjusting the tooth pitch, the adjusting handle 9 rotates, and simultaneously, the adjusting handle slot 91 drives the sliding block connecting cylinder 53 to rotate synchronously around the axis of the adjusting handle 9, thereby adjusting the front and rear position of the cutter head sliding block 5.

[0054] In a preferred example, such as Figure 13 , Figure 14 As shown, the rear part of the cutter head fixing bracket 6 is provided with a pitch block fixing groove 61, and the cutter head pitch spring 7 is disposed in the pitch block fixing groove 61; the first side wall of the pitch block fixing groove 61 abuts against the end of the cutter head pitch spring 7, and the second side wall of the pitch block fixing groove 61 is provided with a fixing slot for engaging and fixing the cutter head pitch block 8. The fixing slot can restrict the cutter head pitch block 8 from rotating synchronously with the adjusting handle 9, and allows the cutter head pitch block 8 to move axially along the adjusting handle 9;

[0055] In more preferred embodiments, the cutter head scale block 8 includes a scale block disc 81 and a scale block positioning hole block 82 disposed on one side of the scale block disc 81; the scale block positioning hole block 82 is sleeved on the outside of the adjustment handle fixing cylinder 93 at the end of the cutter head adjustment handle 9, and the outer wall of the scale block positioning hole block 82 is engaged and fixed in the fixing slot of the second side wall of the scale block fixing groove 61; the cutter head scale spring 7 is always in a compressed state to press the cutter head scale block 8 against the adjustment handle disc 92;

[0056] In this invention, since the adjusting handle slot 91 of the blade adjusting handle 9 is fixed to the sliding block connecting cylinder 53 of the blade sliding block 5, rotating the blade adjusting handle 9 forces the assembly of the upper blade 1, oil storage felt 2, blade guide block 3, tension spring 4, and blade sliding block 5 to move back and forth, thus achieving the tooth pitch adjustment function. Simultaneously, since the adjusting handle wave plate 92 on the blade adjusting handle 9 engages with the pitch block wave plate 81, and the blade pitch block 8 is fixed to the pitch block fixing slot 61 of the blade fixing bracket 6 and cannot rotate, rotating the blade adjusting handle 9, the combined action of the adjusting handle wave plate 92 and the blade pitch spring 7 forces the blade pitch block 8 to reciprocate on the adjusting handle fixing cylinder 93, producing a crisp collision sound. The interlocking pitch block wave plate 81 and adjusting handle wave plate 92 allow the upper blade 1 to stop at a set position, achieving consistent cutting length. The multiple teeth of the wave plate enable switching between multiple gears.

[0057] In this invention, since the tension spring 4 is fixed to the blade sliding block 5, and the blade sliding block 5 moves parallel within the blade fixing bracket slot 62 of the blade fixing bracket 6, and the deformation of the spring does not change during the movement, the pressure generated between the upper blade 1 and the lower blade 10 remains consistent at any position, thereby ensuring that the shearing performance and temperature rise of the blade are consistent at each setting, thus improving the performance of the blade.

[0058] According to the electric hair clipper provided by this utility model, the side-damped adjustable cutter head mechanism for electric hair clippers is adopted, wherein the cutter head guide block 3 is connected to the eccentric shaft of the machine body, and is used to realize left and right reciprocating swing under the drive of the eccentric shaft.

[0059] This invention provides an adjustment method with gear feedback, which can give users a clearer adjustment signal. The gear feedback is obvious when adjusting the blade head, and it has a self-locking function. The number of gears can be changed by adjusting the angle of the gear teeth of the handle. This adjustment method has the advantages of low cost, better reliability and feedback. The spring pressure between the upper and lower blades of each gear is consistent, so that the cutting performance and temperature rise of the blade head are consistent in each gear, thereby improving the performance of the blade head.
