Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical product technology, and in particular to a novel adjustable limiting comb structure applied to a shaver. Background Technology
[0002] The common structure of hair removal combs on the market is that the combs are made with fixed-spaced teeth and are fixed to the hair removal comb with clips. Because the spacing of the combs is fixed, different combs need to be disassembled and replaced to meet different needs when the spacing needs to be changed. The above method requires several combs with different spacing to meet the different needs of consumers. Adjusting the height of the hair removal comb is also relatively troublesome, and the disassembled combs are not easy to store and are easy to lose, causing inconvenience to consumers.
[0003] The existing fixed-gap limit comb structure of shavers has the following shortcomings: the fixed limit gap means that when adjusting the limit gap, it is necessary to replace the limit comb with one of different gaps. Often, multiple sets of limit combs with different gaps need to be equipped for use, which is inconvenient. In addition, multiple sets of limit combs also require more space for packaging and storage, which is inconvenient to store and easy to lose, causing trouble for consumers. Utility Model Content

[0030] The bracket pressure plate 8 covers the top of the adjusting bracket 7 and restricts its vertical movement relative to the screw 6;
[0031] The limiting comb 9 and the cutter head assembly 10 are provided, and the cutter head assembly 10 is located inside the limiting comb 9. The limiting comb 9 is provided with a deformable arm, and the deformable arm is provided with protrusions facing left and right. The front end of the adjusting bracket 7 is provided with symmetrical grooves on both sides.
[0032] Hair baffle 11, upper shell 12 and switch button 13, the hair baffle 11 and the lower shell 1 are connected in parallel to the top of the lower shell 1, and the switch button 13 is located on the upper shell 12;
[0033] The cutter head motor assembly 14 and the fan motor assembly 15 are both located inside the lower shell 1 and the upper shell 12.
[0034] In this utility model, the front end of the lower shell 1 is provided with a limiting comb guide groove, the bottom of the lower shell 1 is provided with a raised truncated cone, the center of the truncated cone is provided with a countersunk hole, and the outer side of the inner hole of the truncated cone is provided with several evenly distributed concave circular groove structures.
[0035] In this invention, the gear adjustment spring block 4 is pushed outward along the guide groove by the elastic force of the spring 5.
[0036] In this utility model, the knob 2 is fitted onto the round platform at the bottom of the lower shell 1, the convex circle of the gear adjustment spring block 4 abuts against the concave circle on the lower shell 1, the knob pressure plate 3 is provided on the countersunk groove of the lower shell and is fixedly connected to the knob 2, and the knob 2 can be rotatably fixed on the lower shell 1.
[0037] In this invention, the adjusting bracket 7 is placed on the limiting comb guide groove inside the lower shell 1.
[0038] More specifically, by setting an adjustment bracket 7 on the limiting comb guide groove inside the lower shell 1, it can slide back and forth as the screw rotates.
[0039] In this utility model, the limiting comb 9 is subjected to a certain external force through the upper limiting comb guide groove of the lower shell 1, and the protrusion of the positioning comb deformation arm can be snapped into the adjustment bracket 7 under the force.
[0040] More specifically, by setting the positioning comb deformation arm so that the protrusion can be engaged with the adjustment bracket 7 under force, it can move back and forth following the movement of the adjustment bracket 7.
[0041] Working Principle: This device utilizes the meshing of the ring teeth on the knob and the gears on the screw. When the knob rotates, the screw rotates accordingly, and the threads on the screw drive the adjusting bracket to move back and forth. The limiting comb connected to the adjusting bracket also moves back and forth accordingly. When the knob rotates, the internal gear adjustment springs jump one by one over the concave circular slots set on the outer side of the inner hole of the lower shell's truncated cone. Jumping from one concave circular slot to an adjacent slot constitutes one gear position. Since the concave circular slots are evenly distributed, the distance the limiting comb moves is the same for each gear position. This allows for accurate setting of the limiting height for each gear position. When the desired limiting distance is adjusted, the screw drive has a self-locking function, and the threaded engagement between the screw and the adjusting bracket achieves self-locking, preventing the limiting comb from loosening under external force and ensuring the stability of the limiting distance adjustment.
