Abstract
Description
Technical Field
[0001] This utility model relates to hair trimming tools, and more specifically, to a nose hair trimmer head assembly. Background Technology
[0002] A nose hair trimmer is a personal care tool used to trim exposed nose hairs. It is classified as a beauty tool and mainly uses a three-dimensional arched blade and an open mesh design to achieve safe trimming, while also maintaining nasal hygiene and personal image.
[0003] Existing nose hair trimmers typically consist of a stationary blade, a moving blade, and a moving blade holder. The moving blade extends into the stationary blade and trims the nose hair as the moving blade holder rotates. However, when the motor drives the moving blade holder to rotate, there is noise generated by the shearing action between the moving blade and the stationary blade. Furthermore, if the moving blade holder scrapes against the stationary blade at high speed, it can easily cause abnormal noise.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a nose hair trimmer head assembly.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a nose hair razor head assembly, including a stationary blade seat, a moving blade and a moving blade seat, wherein a vibration damper is provided on the moving blade seat between it and the stationary blade seat, and the vibration damper is used to block or buffer the mechanical vibration transmitted from the stationary blade seat to the moving blade seat.
[0007] By adopting the above technical solution, this application provides a vibration damper between the stationary blade holder and the moving blade holder, which can isolate the stationary blade holder from the moving blade holder. This reduces the mechanical vibration transmitted from the stationary blade holder to the moving blade holder when the moving blade holder rotates and the moving blade holder rotates, and when cutting the hair. In actual use, the vibration damper can also effectively isolate the mechanical collision between the stationary blade holder and the moving blade holder, thus achieving a good noise reduction effect when the nose hair trimmer is in use.
[0008] The present invention is further configured such that: the moving blade holder includes a connecting part, a limiting part, and a moving blade mounting part; the moving blade is detachably connected to the moving blade mounting part; the planar cross-sectional area of the limiting part is larger than the projected area of the connecting part and the stationary blade holder on the limiting part; and the vibration damper is detachably mounted on the limiting part.
[0009] By adopting the above technical solution, the moving blade holder consists of a connecting part, a limiting part, and a moving blade mounting part. It can be connected to the output end of the brushless motor through the connecting part, thereby driving the moving blade mounting part and the limiting part to rotate. The setting of the limiting part can also effectively support the stationary blade holder, and the setting of the limiting part can also effectively block the hair.
[0010] The present invention is further configured such that: the vibration damper has elastic recovery performance, and a gap is formed between the vibration damper and the limiting part.
[0011] By adopting the above technical solution, the vibration damper has good buffering capacity due to its elastic recovery performance. A gap is reserved between the stationary tool holder and the moving tool holder, and between the stationary tool holder and the vibration damper. This gap allows space for the displacement of the moving and stationary tool holders during vibration, and also avoids the vibration damper from frequently contacting the stationary tool holder under normal conditions, which would hinder the movement of the moving tool holder.
[0012] The present invention is further configured such that: the limiting part has protruding ridges arranged in a ring array on the side facing the stationary knife seat, the top surface of the protruding ridges abuts against the vibration damper, and the gap is formed between adjacent protruding ridges.
[0013] By adopting the above technical solution, the limiting part is provided with a ring array of protruding ridges, which form a gap between the surface of the vibration damper and the limiting part. The structure of the protruding ridges can increase the roughness between the vibration dampers, thereby increasing the stability of the vibration damper.
[0014] The present invention is further configured such that the thickness of the protruding ridge is less than the thickness of the vibration damper.
[0015] By adopting the above technical solution, the thickness of the protruding ridge is less than the thickness of the vibration damper, thereby achieving a gap size smaller than the thickness of the vibration damper, which can accommodate the deformation of the vibration damper during extrusion deformation.
[0016] The present invention is further configured such that: the vibration damper has a ring structure, the vibration damper is sleeved at the connection section between the moving tool mounting part and the limiting part, and a buffer gap is provided between the vibration damper and the stationary tool seat.
[0017] By adopting the above technical solution, the vibration damper has a ring-shaped structure, which makes it easy to fit the vibration damper on the root of the moving tool mounting part. Furthermore, a buffer gap is set between the vibration damper and the stationary tool holder, which can reserve displacement space for the moving or stationary tool holder, further reducing the noise problem caused by collision.
[0018] The present invention is further configured such that: the maximum outer diameter of the stationary blade holder is 8mm, the inner diameter of the stationary blade holder is 6±0.02mm, the maximum distance between the two ends of the adjacent moving blades is 7mm, and the minimum distance between the two ends of the adjacent moving blades is 5mm.
[0019] By adopting the above technical solution, in terms of size settings, the maximum outer diameter of the stationary blade holder is 8mm, while the inner diameter is 6mm, which makes the stationary blade holder have a thinner wall thickness, reducing the amount of hair remaining in the nose hair razor. Furthermore, the maximum distance between the moving blades is 7mm, and the minimum distance is 5mm, so that in the free state, the moving blades can abut against the inner wall of the stationary blade holder to efficiently cut the hair located between them, and there is deformation space, which can efficiently cut different amounts of hair.
[0020] In summary, this utility model has the following beneficial effects: In this application, by setting a vibration damper between the stationary blade holder and the moving blade holder, the vibration damper can isolate the stationary blade holder from the moving blade holder. This reduces the mechanical vibration transmitted from the stationary blade holder to the moving blade holder when the moving blade holder rotates and the moving blade holder rotates, as well as when cutting the hair. In actual use, the vibration damper can also effectively isolate the mechanical collision between the stationary blade holder and the moving blade holder, thus achieving a good noise reduction effect when the nose hair trimmer is in use.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] like Figure 1-5As shown, the nose hair shaving head assembly includes a stationary blade seat 1, a moving blade 2, and a moving blade seat 3. A vibration damper 4 is provided on the moving blade seat 3 between it and the stationary blade seat 1. The vibration damper 4 is used to block or buffer the mechanical vibration transmitted from the stationary blade seat 1 to the moving blade seat 3.
[0025] like Figure 2 and Figure 5 As shown, in this embodiment, the two moving blades 2 are centrally symmetrically arranged and detachably mounted on the moving blade holder 3. The moving blades 2 are provided with a cutting section and a recessed section, while the peripheral wall of the stationary blade holder 1 has a curved side opening. The length of the side opening is longer than the cutting section on the moving blades 2, and the end of the side opening is located within the recessed section. This allows hair to be cut through the contact between the moving blades 2 and the stationary blade holder 1 when it enters between the stationary blade holder 1 and the moving blade holder 3 through the side opening or open inlet. After the hair is cut, it can be discharged through the side opening during the rotation of the moving blades 2. Since the opening length of the side opening is greater than the length of the cutting section, the design of the recessed section and the side opening also allows hair debris to be discharged through the side opening. In this embodiment, the maximum outer diameter of the stationary blade holder 1 is 8 mm, and the inner diameter of the stationary blade holder 1 is 6 ± 0.02 mm. The thinner stationary blade holder 1 reduces the residue of hair debris in the nose hair trimmer and makes it easier to discharge.
[0026] like Figure 2 and Figure 5 As shown, specifically, the moving blade holder 3 includes a connecting part 31, a limiting part 32, and a moving blade mounting part 33. The moving blade 2 is detachably connected to the moving blade mounting part 33. In this embodiment, a vertical groove is provided on the moving blade mounting part 33, and two moving blades 2 are placed symmetrically in the vertical groove. A limiting block is fixedly connected to the moving blade mounting part 33 on the side wall of the vertical groove. There are four limiting blocks, symmetrically arranged on both side walls. The distance between two symmetrically arranged limiting blocks is less than the sum of the thicknesses of the two moving blades 2. This ensures that after the two moving blades 2 are installed, the limiting blocks are precisely located within the movable grooves on the moving blades 2, restricting installation until the moving blade mounting part is installed. When the moving blade on part 33 is disassembled from the moving blade holder 3, it is disengaged from the moving blade mounting part 33 under the action of the spring. The planar cross-sectional area of the limiting part 32 is larger than the projected area of the connecting part 31 and the stationary blade holder 1 on the limiting part 32. The vibration damper 4 is detachably mounted on the limiting part 32 and has elastic recovery performance. In this embodiment, the vibration damper 4 has a ring structure. The vibration damper 4 is sleeved at the connection section between the moving blade mounting part 33 and the limiting part 32. The diameter of the vibration damper 4 is smaller than the diameter of the moving blade mounting part 33, but its deformation can meet the sleeve requirements. A gap is formed between the vibration damper 4 and the limiting part 32.
[0027] like Figure 1 and Figure 2As shown, the limiting part 32 has protruding ribs 34 arranged in a ring array on the side facing the stationary tool holder 1. The top surface of the protruding ribs 34 abuts against the vibration damper 4. The thickness of the protruding ribs 34 is less than the thickness of the vibration damper 4. The gap is formed between adjacent protruding ribs 34. A buffer gap 5 is provided between the vibration damper 4 and the stationary tool holder 1. In this embodiment, the thickness of the protruding ribs 34 is 0.2-0.5 mm. The maximum distance between the two ends of adjacent moving blades 2 is 7 mm, and the minimum distance between the two ends of adjacent moving blades 2 is 5 mm.
[0028] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
