Description

Technical Field

[0001] This application relates to the technical field, and more particularly to a lint remover with a floating blade. Background Technology

[0002] A lint remover is a small electrical appliance used to remove lint balls from the surface of clothing, improving the surface condition and extending the life of the garment. When the lint remover is activated, the blades rotate at high speed and contact the blade guard, creating rigid contact that generates noise and wear. Traditional blade guard covers typically use metal or hard plastic fasteners to rigidly connect the blade guard to the blade head. While this ensures structural stability, at high speeds, the blade head and blade guard are prone to direct scraping due to minor vibrations or assembly tolerances, generating high-frequency noise and causing wear on the blade guard surface, thus reducing its lifespan. Existing improvements include adding rubber pads or using spring structures to adjust the gap, achieving a floating blade guard effect. However, rubber pads are prone to tilting due to uneven pad placement or inconsistent elasticity after prolonged use, affecting cutting performance and generating more noise. Spring-based mechanical structures are complex, significantly increasing the number of parts, assembly processes, and manufacturing costs. Therefore, there is an urgent need for a simple, compact technical solution that allows for adjustment of the gap between the blade guard and the blade head. Utility Model Content

[0003] The purpose of this utility model is to solve the above-mentioned technical problems and provide a lint remover with a floating blade. The blade structure of the lint remover of this application is an integrated design, which is simple and compact, and is easy to manufacture while allowing for dynamic adjustment of the gap.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A lint remover with a floating blade includes a housing, a connector, a blade, a blade cover, and an elastic support, wherein the elastic support is made of silicone. The blade is rotatably mounted in the inner cavity of the housing. One end of the connector is detachably connected to the housing, and the other end is fixedly connected to one end of the elastic support through a secondary molding process. The blade cover includes a cutting end face and a mating wall extending perpendicularly towards the connector. The other end of the elastic support is fixedly connected to the mating wall through a secondary molding process. In its natural state, the elastic support supports the cutting end face to maintain an initial gap with the blade. Under pressure, it undergoes elastic deformation in the vertical direction, causing the blade cover to reduce the initial gap to dynamically adjust the working gap.

[0006] In this application, the elastic support component made of silicone material can undergo elastic deformation under force. It is fixed to the connecting component and the joint wall of the blade cover through a secondary molding process, so that the blade cover has floating support. When no external force is applied, it maintains the initial gap, effectively avoiding friction noise when the blade is spinning idly. When the blade cover is compressed, the elastic support component deforms, causing the blade cover to move towards the blade direction to form an adaptive cutting gap, ensuring the lint removal effect. It effectively reduces noise and wear. The whole is achieved through an integrated structure, which is simple and compact, effectively reducing processing and assembly processes and manufacturing costs.

[0007] In one embodiment, the connection between the elastic support member, the connector, and the joint wall is an interlocking structure with the upper and lower parts aligned with each other.

[0008] In one embodiment, the engagement structure is a trapezoidal convex-concave engagement or a square convex-concave engagement.

[0009] In one embodiment, the inner edge of the end face where the connector connects to the elastic support extends upward to form a limiting wall, and a limiting groove is formed at the position of the connecting wall corresponding to the limiting wall. A gap exists between the side wall of the limiting wall and the limiting groove to form a limiting cavity.

[0010] In one embodiment, the connector has a first connecting groove, the joint wall has a second connecting groove, and both ends of the elastic support protrude to form connecting ribs during the molding process. The connecting ribs are respectively fitted into the first connecting groove and the second connecting groove.

[0011] In one embodiment, the connecting rib has a trapezoidal structure.

[0012] In one embodiment, the edges of the connecting ribs have a wavy or serrated structure.

[0013] In one embodiment, the initial gap is 0.1-0.5 mm in size, and the working gap is adjustable within the range of 0-0.5 mm.

[0014] In one embodiment, the blade cover includes a fixed cover and a metal mesh cover, the fixed cover being fixedly connected to the elastic support member; the metal mesh cover is fixedly disposed in the middle of the fixed cover, and the end face of the fixed cover connected to the metal mesh cover is inclined towards the middle; the gap between the metal mesh cover and the blade constitutes the working gap.

[0015] In one embodiment, the elastic support is made of silicone material with a Shore hardness of 30A-60A. Attached Figure Description

[0023] This application provides a lint remover with a floating blade net to solve the technical problem in existing improved solutions where some technologies adjust the gap by adding rubber pads or using spring structures, which, although able to adjust the gap, significantly increase the number of parts and manufacturing costs.

[0024] To make the inventive objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figures 1 to 7This application provides a lint remover with a floating blade mesh, including a housing 100, a connector 200, a blade 300, a blade mesh cover 400, and an elastic support 500. The elastic support 500 is made of silicone. The blade 300 is rotatably mounted in the inner cavity of the housing 100. One end of the connector 200 is detachably connected to the housing 100, and the other end is fixedly connected to one end of the elastic support 500 through a secondary molding process. The blade mesh cover 400 includes a cutting end face 410 and a connecting wall 420 extending perpendicularly towards the connector 200. The other end of the elastic support 500 is fixedly connected to the connecting wall 420 through a secondary molding process. In its natural state, the elastic support 500 supports the cutting end face 410 to maintain an initial gap with the blade 300. Under pressure, it undergoes elastic deformation in the vertical direction, causing the blade mesh cover to reduce the initial gap to dynamically adjust the working gap.

[0026] Specifically, the inner cavity of the housing 100 forms an installation cavity. The connector 200 is connected to the housing 100 by threads for detachable installation. The blade 300 is installed in the inner cavity of the housing 100 and rotates under the drive of the drive motor to cut fuzz balls. The end face of the blade 300 that cuts fuzz balls is the cutting end face 410. The edge of the cutting end face 410 extends towards one side of the connector 200 to form a joint wall 420. The elastic support 500 is connected and formed with the connector 200 and the joint wall 420 through a secondary molding process. The elastic support 500 forms an elastic layer with elastic deformation. Through staged molding, the connector cover, the blade cover, and the silicone elastic support 500 are efficiently combined, effectively reducing production and assembly processes. At the same time, the blade cover 400 has a floating effect, reducing manufacturing costs. Under the support of the elastic support 500, the blade cover 400 has an initial gap with the cutting surface of the blade 300 in its natural state. When the drive motor is turned on... The rear blade 300 rotates without friction with the blade cover 400, thus avoiding noise and wear. When subjected to force and undergoing elastic deformation, the resulting working gap narrows, allowing the blade 300 to contact the cutting surface for efficient lint removal. In this embodiment, the elastic support 500 is made of silicone material with a Shore hardness of 30A-60A, ensuring sufficient strength while allowing for elastic deformation under force. The initial gap is 0.1-0.5mm, and the adjustable working gap is 0-0.5mm, ensuring sufficient elastic deformation of the elastic support 500. Furthermore, the elastic connector 200 in this embodiment is annular, with flat surfaces at both ends connecting to the connector 200 and the blade cover 400, resulting in a simple structure that is easy to mold. Through integrated structural design, the structural stability of the elastic connector 200 is ensured during dynamic gap adjustment, and the simple and compact structure effectively reduces processing steps and manufacturing costs.

[0027] See Figures 5-6 As one embodiment, the connection between the elastic support 500, the connector 200, and the joint wall 420 is an interlocking structure with the upper and lower parts aligned with each other. The interlocking structure is either a trapezoidal or square interlocking structure. The top of the connector 200 forms a protrusion, and the joint wall 420 forms a groove at the corresponding position. The space formed between the connector 200 and the joint wall 420 is the forming part of the elastic support 500, so that the connector 200 and the joint wall 420 form an engagement structure. In this embodiment, the engagement structure is a square with concave and convex engagement. In other embodiments, the engagement position can also be a trapezoidal concave and convex engagement (not shown in the figure). This effectively increases the contact area between the elastic support 500 and the connector 200 and the joint wall 420, improving the connection stability. At the same time, the elastic support 500 is not prone to displacement when it drives the blade cover 400 to move during the elastic deformation process, forming an axial constraint. This ensures that the blade 300 is not easily deflected when cutting with the blade cover 400, which would affect normal use and improve the user experience of the product.

[0028] participate Figure 7 In another embodiment, the inner edge of the end face where the connector 200 connects to the elastic support 500 extends upward to form a limiting wall 210. The connecting wall 420 has a limiting groove 421 at the position corresponding to the limiting wall 210. A gap exists between the side wall of the limiting wall 210 and the limiting groove 421, forming a limiting cavity 4211. The limiting cavity 4211 formed between the limiting wall 210 and the limiting groove 421 ensures that during deformation of the elastic support 500, when the blade cover 400 shifts to one side due to uneven force, the inner side of the limiting wall 210 shifts into the limiting cavity 4211 and abuts against the side wall of the limiting groove 421, thus being limited. This ensures that the horizontal displacement distance of the blade cover 400 is restricted, allowing the blade cover 400 to maintain normal cutting operation and improving the user experience.

[0029] Furthermore, the connector 200 has a first connecting groove 210, the joint wall 420 has a second connecting groove 422, and both ends of the elastic support 500 protrude during the molding process to form connecting ribs 510, which are respectively fitted into the first connecting groove 220 and the second connecting groove 422. The connecting ribs 510 have a trapezoidal structure. The cross-section of the connecting ribs 510 is trapezoidal, and the formation of the first connecting groove 220 and the second connecting groove 422 corresponds to the connecting ribs 510, ensuring the connection stability of the elastic support 500 and facilitating molding. In other embodiments, the edges of the connecting ribs 510 have a wavy or sawtooth structure (not shown in the figure) to increase the connection area and improve the connection stability of the elastic support 500, making the joint less prone to breakage.

[0030] Furthermore, the blade cover 400 includes a fixed cover 430 and a metal mesh cover 440. The fixed cover 430 is fixedly connected to the elastic support member 500. The metal mesh cover 440 is fixedly disposed in the middle of the fixed cover 430, and the end face of the fixed cover 430 connected to the metal mesh cover 440 is inclined towards the middle. The gap between the metal mesh cover 440 and the blade 300 constitutes the working gap. The middle part of the fixed cover 430 is a cutting end face 410, and the metal mesh cover 440 is fitted into the middle part of the cutting end face 410. The cutting end face 410 is inclined towards the metal mesh cover 440. The side wall of the blade cover 400 is a joining wall 420. Through secondary forming with the elastic support member 500, it is ensured that the elastic support member 500 and the blade cover 400 are easy to manufacture.
