Description

Technical Field

[0001] The utility model relates to the technical field of nose hair trimming, in particular to a nose hair trimmer with shock absorption and noise reduction functions. Background Art

[0002] A nose hair trimmer is a personal care appliance, mainly used to trim excessively long nose hairs to maintain the hygiene and beauty of the nasal cavity. The nose hair trimmer is compact and easy to carry, and can trim nose hairs in any direction and length without damaging the nasal cavity.

[0003] When the nose hair trimmer is working, the motor drives the blade to rotate at high speed, and the high-speed cutting of the blade trims the excessively long nose hair to the appropriate length. The design of the nose hair trimmer usually includes additional features such as a protective cover or blade spring to protect the nasal cavity from unnecessary damage.

[0004] The Chinese utility model patent with patent application number CN202322196177.0 records a nose hair trimmer, which forms a stable connection in the first, second and third directions perpendicular to each other through the interconnected trimmer body, shell and connecting piece, thereby avoiding separation under the impact of external force and preventing loosening and detachment between the trimmer body, shell and connecting piece. However, during the operation of the above-mentioned nose hair trimmer, since the blade needs to rotate at high speed driven by the motor, the motor will inevitably vibrate, which will cause the user's hand holding the shell to receive strong vibration and cause discomfort when using the nose hair trimmer, and will also generate loud noise, seriously affecting the user experience and reducing the practicality of the nose hair trimmer. Utility Model Content

[0005] The purpose of the present utility model is to provide a nose hair trimmer with shock absorption and noise reduction function, so as to solve the problem that the existing nose hair trimmer proposed in the above background technology will generate vibration and noise due to the shaking of the motor during use, which seriously affects the user experience and reduces the practicality of the nose hair trimmer.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: a nose hair trimmer with shock absorption and noise reduction functions, comprising a housing, a protective head being clamped to the top of the housing via a snap-fit ​​structure, a blade being rotatably connected to the protective head, a mounting cavity being provided in the housing, an inner side wall of the mounting cavity being covered and connected with a first shock-absorbing layer, a fixing box being fixedly connected to the bottom wall of the mounting cavity, a motor being fixedly connected to the fixing box, an output end of the motor passing through the top wall of the fixing box and connected to the blade, and a plurality of shock-absorbing units being equidistantly sleeved on the outer surface of the fixing box from top to bottom;

[0007] The shock absorbing unit includes a plurality of shock absorbing members, which are connected to the outer surface of the fixing box in a ring shape, and are tightly pressed against the inner side wall of the first shock absorbing layer.

The connecting block is connected to the side surface of the fixed box, and the end of the first rotating rod away from the connecting block is tightly against the inner side surface of the first shock-absorbing layer. The advantage of such a setting is that the vibration generated by the motor can be dispersed more evenly, further improving the effect of shock absorption and noise reduction.

[0009] Preferably, the shock-absorbing unit also includes a circular mounting box, a second shock-absorbing layer is fixedly sleeved on the outer side surface of the mounting box, the second shock-absorbing layer is fixedly connected to the inner side surface of the first shock-absorbing layer, the inner circular surface of the mounting box is through-connected, and multiple pairs of first rotating rods pass through the inner circle of the mounting box at one end away from the connecting block and extend inside the mounting box, the first rotating rods are rotatably connected to the end away from the connecting block with a roller, and the roller conflicts with the inner wall of the outer side surface of the mounting box. The advantage of such a setting is that the shock-absorbing component can perform buffering and shock-absorbing work more stably and reliably, further improving the shock-absorbing and noise reduction effect of the shock-absorbing unit.

[0010] Preferably, the multiple shock-absorbing members are divided into multiple groups, and the multiple groups of shock-absorbing members are distributed at equal angles in a ring shape, and the multiple shock-absorbing members in each group are distributed at equal angles. Two shock-absorbing columns are symmetrically fixedly connected to the two outermost first rotating rods in each group of shock-absorbing members, and the distant ends of two adjacent shock-absorbing columns on any two groups of shock-absorbing members can collide with each other. The advantage of such a setting is that by driving the adjacent shock-absorbing columns to collide when the multiple groups of first rotating rods rotate, the energy generated by the motor vibration can be effectively consumed, further improving the shock absorption and noise reduction effect of the shock-absorbing unit.

[0011] Preferably, the installation box is split into upper and lower parts, and the upper and lower parts are buckled together. The advantage of this arrangement is that it is easy to install the shock-absorbing part inside the installation box, further improving the practicality of the trimmer.

[0012] Preferably, the middle portion of the outer side surface of the shell is an inwardly concave curved surface. The advantage of such a setting is that it can enhance the comfort when holding and improve the practicality of the trimmer.

[0013] Preferably, the number of shock-absorbing components in each group is not less than three, and the number of shock-absorbing component groups in the installation box is not less than three. The advantage of such an arrangement is that the vibration generated by the motor can be further evenly distributed, thereby further improving the effect of shock absorption and noise reduction.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example 1

[0027] Please refer to Figure 1-Figure 5 The nose hair trimmer with shock absorption and noise reduction functions shown in the figure includes a housing 1, a protective head 2 is clamped to the top of the housing 1 via a snap structure, a blade is rotatably connected to the protective head 2, a mounting cavity 3 is provided in the housing 1, the inner side wall of the mounting cavity 3 is covered and connected with a first shock absorption layer 4, a fixing box 5 is fixedly connected to the bottom wall of the mounting cavity 3, a motor 6 is fixedly connected to the fixing box 5, the output end of the motor 6 passes through the top wall of the fixing box 5 and is connected to the blade, and a plurality of shock absorption units 7 are equidistantly sleeved on the outer surface of the fixing box 5 from top to bottom;

[0028] The shock absorbing unit 7 includes a plurality of shock absorbing members 71 . The plurality of shock absorbing members 71 are connected to the outer surface of the fixing box 5 in a ring shape. The plurality of shock absorbing members 71 are tightly against the inner wall of the first shock absorbing layer 4 .

[0029] refer to Figure 3-Figure 5 The shock absorber 71 includes a fixed column 711, a connecting block 712 is fixedly sleeved in the middle position of the fixed column 711, and a first rotating rod 713 is rotatably sleeved on the top and bottom ends of the fixed column 711. The two first rotating rods 713 are distributed in an eight-shaped shape, and two first torsion springs 714 are symmetrically fixedly connected between the top and bottom of the connecting block 712 and the side surfaces close to the two first rotating rods 713. The connecting block 712 is connected to the side surface of the fixed box 5, and the end of the first rotating rod 713 away from the connecting block 712 is tightly pressed against the inner side surface of the first shock-absorbing layer 4.

[0030] Specifically, when the motor 6 vibrates and drives the fixed box 5 to vibrate, the fixed box 5 will squeeze the connecting block 712, so that the two first rotating rods 713 rotate in directions away from each other. In this way, under the elastic buffering of the first torsion spring 714, the vibration can be effectively reduced. At the same time, each shock absorbing unit 7 includes a plurality of shock absorbing parts 71 connected in a ring shape to the outer surface of the fixed box 5, which can make the vibration generated by the motor 6 be more evenly dispersed, further improving the effect of shock absorption and noise reduction.

[0031] refer to Figure 2-Figure 4 The shock-absorbing unit 7 also includes a circular mounting box 72, on the outer surface of which a second shock-absorbing layer 73 is fixedly sleeved. The second shock-absorbing layer 73 is fixedly connected to the inner surface of the first shock-absorbing layer 4. The inner circular surface of the mounting box 72 is through-circular, and one end of multiple pairs of first rotating rods 713 away from the connecting block 712 passes through the inner circle of the mounting box 72 and extends into the interior of the mounting box 72. The one end of the first rotating rod 713 away from the connecting block 712 is rotatably connected to a roller 74, and the roller 74 conflicts with the inner wall of the outer surface of the mounting box 72.

[0032] Specifically, the first rotating rod 713 can be limited by the mounting box 72, and the roller 74 can make the shock absorbing member 71 more stable and reliable in performing the buffering and shock absorbing work, further improving the shock absorbing and noise reduction effect of the shock absorbing unit 7;

[0033] The mounting box 72 is split into upper and lower parts, and the upper and lower parts are buckled together, which makes it easy to install the shock-absorbing member 71 inside the mounting box 72, further improving the practicality of the trimmer.

[0034] refer to Figure 3-Figure 5 The multiple shock absorbers 71 are divided into multiple groups, and the multiple groups of shock absorbers 71 are distributed at equal angles in a ring shape.

The ends of two adjacent shock absorber columns 75 on any two groups of shock absorbers 71 that are away from each other can collide with each other.

[0035] Specifically, by driving the adjacent shock-absorbing columns 75 to collide when the multiple groups of first rotating rods 713 rotate, the energy generated by the vibration of the motor 6 can be effectively consumed, further improving the shock-absorbing and noise-reducing effect of the shock-absorbing unit 7.

[0036] refer to Figure 2 and Figure 4 The installation box 72 is a split type with upper and lower parts, and the upper and lower parts are buckled together.

[0037] Specifically, it is convenient to install the shock absorbing member 71 inside the installation box 72, thereby further improving the practicality of the trimmer.

[0039] Specifically, the gripping area of ​​the housing 1 is made to better conform to the physiological curve of the human hand, thereby improving the comfort when gripping and enhancing the practicality of the trimmer.

[0040] refer to Figure 3 and Figure 4 The number of shock-absorbing members 71 in each group is not less than three, and the number of shock-absorbing members 71 in the installation box 72 is not less than three.

[0041] Specifically, the vibration generated by the motor 6 can be evenly distributed, thereby further improving the effect of vibration reduction and noise reduction.

[0042] refer to Figure 1 and Figure 2 The gap between the fixing box 5 and the shell 1 is filled with sound insulation material, and the outer side of the shell 1 is fixedly sleeved with a third shock-absorbing layer 8.

[0043] Specifically, the sound insulation material and the third shock-absorbing layer 8 can maximize the quietness of the trimmer, greatly improving the practicality and user experience of the trimmer.
