Description

Technical Field

[0001] This utility model belongs to the field of noise-reducing curling iron technology, and specifically relates to a noise-reducing curling iron. Background Technology

[0002] As an everyday hair styling appliance, curling irons use high-speed airflow in conjunction with heating elements to create curls. Their convenience and quick drying function are highly favored by consumers. However, when the curling iron is running, the turbulent airflow at the fan inlet can easily generate harsh noise. Moreover, the complex internal air duct structure makes cleaning and maintenance difficult. After long-term use, hair tangling or dust accumulation can affect airflow efficiency, thereby exacerbating the noise problem and limiting the user experience. Although existing noise-reducing curling irons have a fan inlet structure designed to divide the airflow and reduce noise, they generally have the following drawbacks: First, the fan inlet is mostly fixed and requires tools or complicated operations to disassemble, which makes daily cleaning and maintenance difficult for users. Hair and dust easily accumulate in the mesh, gradually blocking the airflow channel and causing eddy noise to rebound. Utility Model Content

[0003] In view of this, the present invention provides a noise-reducing curling iron, which can be evenly dispersed into fine streamlines through the mesh holes of the air filter, significantly reducing the eddy noise generated by the violent collision between air molecules, thus achieving efficient noise reduction. In daily use, users can monitor the status of the air filter and disassemble and install it by hand without tools through the snap-on structure, which significantly reduces the difficulty of cleaning operations and prevents the noise reduction performance from being reduced due to hair entanglement and blockage. Maintenance can be performed quickly with just a pull and a push.

[0004] To address the aforementioned technical problems, this utility model provides a noise-reducing curling iron, comprising a housing and a plurality of bristles evenly arranged at the end of the outer arc surface. A fan is installed inside the housing, and a noise-reducing mechanism for reducing noise at the fan's air inlet is provided inside the housing. The noise-reducing mechanism includes an arc-shaped opening at the end of the outer arc surface of the housing, and an arc-shaped insert plate is movably inserted into the arc-shaped opening. An air mesh is provided on the inner arc surface of the arc-shaped insert plate. The air mesh abuts against the fan's air inlet through a sealing element. The diameter of the air mesh is larger than the diameter of the fan's air inlet, meaning that the air is evenly dispersed into fine streamlines through the mesh holes of the air mesh, significantly reducing the eddy noise generated by the violent collision between air molecules, achieving efficient noise reduction. In daily use, the user can monitor the status of the air mesh and disassemble it by hand without tools through the snap-on structure, significantly reducing the difficulty of cleaning operations and preventing the noise reduction performance from being reduced due to hair entanglement and blockage. Maintenance can be performed quickly with a simple pull and push. The noise reduction mechanism also includes mounting slots symmetrically arranged at both ends of the arc-shaped insert plate. Each mounting slot is rotatably connected to a limiting plate. Each end wall of the arc-shaped opening has a slot, and each slot has a limiting protrusion. The limiting plate is engaged with the adjacent limiting protrusion on the same side. The mounting slot is also equipped with an unlocking component for unlocking the limiting plate, thus enabling quick insertion of the wind network.

[0005] The limiting plate has an L-shaped structure, and the inner side of the short side of the limiting plate is inclined from the inside to the outside, so that the various structures can be smoothly inserted.

[0006] The unlocking mechanism includes a pressing plate that is slidably connected to the mounting groove. The inner end of each pressing plate is provided with a groove, and the ends of the limiting plates are located in adjacent grooves on the same side, so that the relevant user can operate.

[0007] The unlocking component also includes cylinders that are rotatably connected to the slots. The ends of the limiting plates are provided with rounded rectangular slots. The cylinders roll into the adjacent rounded rectangular slots on the same side, which achieves the function of rapid transmission.

[0008] The unlocking mechanism also includes springs respectively disposed between the pressing plate and its mounting slot, which provide elastic force to the pressing plate.

[0009] The sealing components include a sealing ring installed at the air inlet of the fan. The air mesh abuts against the sealing ring to prevent airflow leakage and the resulting turbulence noise.

[0010] An observation plate is provided at the end of the outer arc surface of the shell, which can monitor the status of the air network in real time to avoid blockage.

[0011] The beneficial effects of the above-mentioned technical solution of this utility model are as follows: 1. The edge of the air mesh is tightly pressed against the air inlet of the fan by a sealing component, forming a sealed airflow channel. The high-speed airflow is evenly dispersed into fine streamlines through the mesh holes of the air mesh, which significantly reduces the eddy noise generated by the violent collision between air molecules, achieving efficient noise reduction. In daily use, users can monitor the status of the air mesh. When a blockage is found, the air mesh can be quickly removed by simply pulling out the arc-shaped insert. After cleaning, the operation is reversed to achieve proper insertion, preventing the noise reduction performance from being reduced due to hair entanglement and blockage. Maintenance can be performed quickly with just a pull and a push.

[0012] 2. Quick installation is achieved by engaging the limiting plates at both ends of the arc-shaped insert with the limiting protrusions in the slots on the inner wall of the arc-shaped opening of the housing. When blockage is detected, simply press the pressing plate inward in the installation slot. The linkage between the cylinder and the rounded rectangular slot causes the limiting plate to rotate and disengage from the limiting protrusion. At this point, gently pull the arc-shaped insert outward to quickly remove the air filter. After cleaning, reverse the operation to achieve proper insertion. During insertion, the limiting protrusion will contact the inclined surface of the limiting plate, and the two will slide relative to each other. At this time, the limiting plate will tilt up to avoid the contact until the arc-shaped insert is fully engaged with the arc-shaped opening. At this point, the limiting plate will simultaneously engage with the corresponding limiting protrusion, thus achieving the fixed installation of the air filter. The snap-fit ​​structure allows for manual installation and removal without tools, significantly reducing the difficulty of cleaning operations.

[0013] 3. The interference fit of the sealing ring ensures airtightness after reset, preventing airflow leakage and turbulence noise. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0017] This embodiment provides a noise-reducing curling iron, such as Figure 1-4 As shown: The device includes a housing 100 and a plurality of bristles 101 evenly arranged at the end of the outer arc surface. A fan 102 is installed inside the housing 100. The housing 100, bristles 101, and fan 102 are all common structures in this technical field and are not innovative here. The housing 100 is provided with a noise reduction mechanism for reducing noise at the air inlet of the fan 102. The noise reduction mechanism includes an arc-shaped opening 200 located at the end of the outer arc surface of the housing 100. The arc-shaped opening 200 is semi-circular. An arc-shaped insert plate 201 is movably inserted into the arc-shaped opening 200. An air mesh 202 is provided on the inner arc surface of the arc-shaped insert plate 201. The air mesh 202 abuts against the air inlet of the fan 102 through a sealing element. The diameter of the air mesh 202 is larger than the diameter of the air inlet of the fan 102. The air mesh 202 can completely block the air inlet of the fan 102 to ensure thorough dispersion of airflow and improve the noise reduction effect.

[0018] The edge of the air mesh 202 is tightly pressed against the air inlet of the fan 102 by a sealing element, forming a sealed airflow channel. The high-speed airflow is evenly dispersed into fine streamlines through the mesh holes of the air mesh 202, which significantly reduces the eddy noise generated by the violent collision between air molecules and achieves efficient noise reduction. In daily use, users can monitor the status of the air mesh. When a blockage is found, the air mesh 202 can be quickly removed by simply pulling out the arc-shaped insert plate 201. After cleaning, the operation is reversed to achieve proper insertion, preventing the noise reduction performance from being reduced due to hair entanglement and blockage. Maintenance can be performed quickly with just a pull and a push.

[0019] like Figure 1-4 As shown, the noise reduction mechanism also includes mounting grooves 203 symmetrically arranged at both ends of the arc-shaped insert 201. Each mounting groove 203 has a limiting plate 204 rotatably connected to it. Slots 205 are provided on both ends of the arc-shaped opening 200, and each slot 205 contains a limiting protrusion 206. The limiting plate 204 engages with the adjacent limiting protrusion 206 on the same side. The mounting groove 203 also contains an unlocking component for unlocking the limiting plate 204. The limiting plate 204 has an L-shaped structure, and the inner side of its short side is inclined from the inside out. The device includes a pressing plate 300 that is slidably connected to the mounting groove 203. Each pressing plate 300 has a groove 301 on its inner end. The ends of the limiting plate 204 are located in adjacent grooves 301 on the same side. The unlocking device also includes a cylinder 302 that is rotatably connected to the groove 301. Each end of the limiting plate 204 has a rounded rectangular groove 303. The cylinder 302 rolls with the adjacent rounded rectangular groove 303 on the same side. The unlocking device also includes a spring 304 that is disposed between the pressing plate 300 and the mounting groove 203.

[0020] The limiting plates 204 at both ends of the arc-shaped insert 201 engage with the limiting protrusions 206 in the slots 205 on the inner wall of the arc-shaped opening 200 of the housing 100, enabling quick installation. When blockage is detected, the user simply presses the pressing plate 300 inward within the installation slot 203. The pressing plate 300, through the linkage between the cylinder 302 and the rounded rectangular slot 303, causes the limiting plate 204 to rotate and disengage from the limiting protrusions 206. At this point, the user can easily remove the air filter 202 by gently pulling the arc-shaped insert 201 outward. This allows for quick disassembly of the air filter 202. After cleaning... After completion, the reverse operation is performed to achieve the alignment and insertion of the air net 202. During the insertion of the air net 202, the limiting protrusion 206 will contact the inclined surface of the limiting plate 204, and the two will slide relative to each other. At this time, the limiting plate 204 will tilt up to avoid it until the arc-shaped insert 201 and the arc-shaped opening 200 are fully engaged. At this time, the limiting plate 204 will simultaneously engage with the corresponding limiting protrusion 206 to achieve the fixed installation of the air net 202. The snap-fit ​​structure allows for manual disassembly and assembly without tools, significantly reducing the difficulty of cleaning operations and ensuring that the air net 202 can be cleaned quickly.

[0021] like Figure 2-4 As shown, the sealing element includes a sealing ring 400 disposed at the air inlet of the fan 102, and the air mesh 202 abuts against the sealing ring 400.

[0022] The interference fit of the 400 sealing ring ensures airtightness after reset, preventing airflow leakage and turbulence noise.

[0023] like Figure 1 As shown, an observation plate 500 is provided at the end of the outer arc surface of the housing 100.

[0024] The observation board 500 can monitor the status of the air network 202 in real time to avoid blockage and facilitate timely cleaning of the air network 202 by the user.

[0025] The working principle of the noise-reducing hair curler provided by this utility model is as follows: When the hair curler is started, the limiting plates 204 at both ends of the arc-shaped insert plate 201 are pre-engaged with the limiting protrusions 206 of the inner wall slot 205 of the arc-shaped opening 200 of the housing 100, completing the quick installation. At this time, the edge of the air mesh 202 is tightly pressed against the sealing ring 400 of the air inlet of the fan 102, forming a sealed airflow channel. The high-speed airflow is evenly dispersed into fine streamlines through the mesh holes of the air mesh 202, significantly reducing the eddy noise generated by the violent collision between air molecules, achieving efficient noise reduction. In daily use, the user can intuitively monitor the status of the air mesh through the observation plate 500. When a blockage is found, simply press the pressing plate 300 in the mounting slot 203 inward. Through the linkage between the cylinder 302 and the rounded rectangular slot 303, the limiting plate 204 is rotated. After disengaging from the limiting protrusion 206, gently pull outwards the arc-shaped insert plate 201 to quickly remove the air mesh 202. After cleaning, reverse the operation to achieve proper insertion. During insertion, the limiting protrusion 206 will contact the inclined surface of the limiting plate 204, and the two will slide relative to each other. At this time, the limiting plate 204 will tilt up to avoid it until the arc-shaped insert plate 201 and the arc-shaped opening 200 are fully engaged. At this time, the limiting plate 204 will simultaneously engage with the corresponding limiting protrusion 206 to achieve fixed installation of the air mesh 202. The interference fit of the sealing ring 400 ensures the airtightness after reset. The observation plate 500 can monitor the status of the air mesh 202 in real time to avoid blockage. The snap-fit ​​structure allows for manual disassembly and assembly without tools, significantly reducing the difficulty of cleaning operations and preventing noise reduction performance degradation caused by hair entanglement and blockage. Maintenance can be performed quickly with just a pull and a push.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
