Description

Technical Field

[0001] This application relates to the field of lint remover technology, 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 starts working, the blades begin to rotate at high speed and come into contact with the blade guard, creating rigid contact between the blade guard and the blade head, which generates noise and wear. Traditional blade guard components typically use metal or hard plastic fasteners to rigidly connect the blade guard and 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, reducing its lifespan. Existing improvements include adding rubber pads or using spring structures to adjust the gap, achieving a floating blade guard effect. However, using rubber pads can lead to blade guard 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 and significantly increase 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 realized through an integrated structure, which is simple and compact and easy to manufacture.

[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 connecting cover, blades, a blade assembly, and an elastic connector, the elastic connector being made of silicone. The blades are rotatably mounted in the inner cavity of the housing. The connecting cover includes an annular wall, one end of which is detachably connected to the housing, and the other end extends laterally towards the blade to form a connecting flange. One end of the elastic connector is fixedly connected to the connecting flange through a secondary molding process, and the other end is fixedly connected to the edge of the blade assembly through a secondary molding process. In its natural state, the elastic connector supports the blade assembly, maintaining an initial gap between it and the blade. Under pressure, it causes the blade assembly to elastically deform in the vertical direction, reducing the initial gap to dynamically adjust the working gap.

[0006] In this application, the connecting flange formed by the elastic connector and the connecting cover, and the edge of the blade mesh are fixedly connected by secondary molding. Under the elastic action of the elastic connector, the blade mesh has floating support and maintains the initial gap when not subjected to external force, effectively avoiding friction noise when the blade is spinning idly. When the blade mesh is compressed, the elastic connector deforms, causing the blade mesh to move towards the blade direction to form an adaptive cutting gap, ensuring the lint removal effect. While effectively reducing 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, one end of the elastic connector is fitted to the side end face of the connecting flange through a secondary forming connection, and the other end is fitted to the circumferential edge of the blade mesh through a secondary forming connection.

[0008] In one embodiment, the bottom of the elastic connector is fitted to the outer side of the connecting flange through a secondary molding connection, and the top is fitted to the bottom edge of the blade mesh through a secondary molding connection.

[0009] In one embodiment, the connecting flange has a first connecting groove, the blade mesh has a second connecting groove, and the inner and outer edges of the elastic connector both protrude to form connecting ribs during the forming process. The connecting ribs are respectively fitted into the first connecting groove and the second connecting groove.

[0010] In one embodiment, the connecting rib has a trapezoidal structure.

[0011] In one embodiment, the edges of the connecting ribs have a wavy or serrated structure.

[0012] In one embodiment, the connecting cover is installed to the housing via a threaded connection.

[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 mesh component includes a blade mesh frame and a metal mesh cover, the blade mesh frame being fixedly connected to the elastic connector; the metal mesh cover being fixedly disposed on the inner side of the blade mesh frame; the gap between the metal mesh cover and the blade constitutes the working gap.

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

[0021] This application provides a lint remover with a floating blade net to solve the technical problem in existing improved solutions where some technologies, by adding rubber pads or using spring structures to adjust the gap, can alleviate instantaneous impact, but also significantly increase the number of parts and manufacturing costs.

[0022] 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.

[0023] Please see Figures 1 to 5 This application provides a lint remover with a floating blade mesh, including a housing 100, a connecting cover 110, a blade 200, a blade mesh 300, and an elastic connector 400. The elastic connector 400 is made of silicone. The blade 200 is rotatably mounted in the inner cavity of the housing 100. The connecting cover 110 includes an annular wall. One end of the annular wall 110 is detachably connected to the housing 100, and the other end extends laterally towards the blade 200 to form a connecting flange 112. One end of the elastic connector 400 is fixedly connected to the connecting flange 112 by secondary molding, and the other end is fixedly connected to the edge of the blade mesh 300 by secondary molding. In its natural state, the elastic connector 400 supports the blade mesh 300 to maintain an initial gap with the blade 200. In a compressed state, it causes the blade mesh 300 to undergo elastic deformation in the vertical direction to reduce the initial gap and dynamically adjust the working gap.

[0024] Specifically, the blade 200 is installed inside the cavity of the housing 100 and can rotate for cutting. The bottom connecting surface of the connecting cover 110 is connected to the housing 100 by a thread to form a detachable connection, which is convenient for installation. The top edge extends laterally towards the center to form an annular connecting flange 112 on the upper side of the corresponding blade 200. The two ends of the elastic connector 400 made of silicone material are respectively connected to the connecting flange and the blade mesh through secondary molding. The connecting cover, the blade mesh and the elastic connector of silicone material are efficiently combined through staged molding, which effectively reduces the production assembly process and reduces manufacturing costs. In this embodiment, the elastic connector is preferably made of silicone material with a Shore hardness of 30A-60A to ensure that it has sufficient strength and can produce elastic deformation under force. In its natural state, the blade mesh Supported by the elastic connector 400, the component 300 has an initial gap with the blade 200. At this time, when the blade 200 rotates, it will not rub against the blade mesh, thus effectively preventing no-load noise and wear. When in use, the elastic connector 400 can undergo elastic deformation after being subjected to force, and the blade mesh component 300 moves closer to the blade 200, thus effectively cutting lint at high speed. In this embodiment, the size of the initial gap is 0.1-0.5mm, and the adjustable range of the working gap is 0-0.5mm. By dynamically adjusting the working gap, the blade mesh can float. Through the integrated structural design, the structural stability of the elastic connector is ensured when the gap is dynamically adjusted, and the structure is simple and compact, effectively reducing the processing steps and manufacturing costs.

[0025] Furthermore, one end of the elastic connector 400 is fitted with the side face of the connecting flange 112 through a secondary molding process, and the other end is fitted with the circumferential edge of the blade mesh 300 through a secondary molding process. The inner and outer circumferences of the elastic connector 400 are fitted with the connecting flange 112 and the blade mesh 300 respectively, and the secondary molding process quickly fixes the connection, so that the blade mesh 300 is fixed on the connecting cover 110 and the working gap between it and the blade 200 can be dynamically adjusted. The structure is simple and easy to manufacture.

[0026] See Figures 4 to 5 In another embodiment, the bottom of the elastic connector 400 is fitted to the outer side of the connecting flange 112 through a secondary molding process, and the top is fitted to the bottom edge of the blade mesh 300 through a secondary molding process. In this embodiment, the upper and lower end faces of the elastic connector 400 are fitted to the outer side of the connecting flange 112 and the bottom edge of the blade mesh 300 through a secondary molding process. While fixing the blade mesh 300, the elastic connector 400 can also adjust the working gap of the blade mesh when subjected to force, ensuring that the blade 200 can efficiently cut fuzz balls.

[0027] Furthermore, the connecting flange 112 has a first connecting groove 1121, and the blade mesh 300 has a second connecting groove 310. During the molding process, the inner and outer edges of the elastic connector 400 both protrude to form connecting ribs 410, which are respectively fitted into the first connecting groove 1121 and the second connecting groove 310. In this embodiment, the cross-section of the connecting rib 410 is trapezoidal, and the formation of the first connecting groove 1121 and the second connecting groove 310 corresponds to the connecting rib 410, ensuring connection stability while facilitating molding. In another embodiment, the outer periphery of the connecting rib 410 can be wavy or serrated (not shown in the figure) to increase the connection area. During the secondary molding process, the elastic connector 400 made of silicone material, through the interlocking of the connecting ribs 410 with the first connecting groove 1121 and the second connecting groove 310, ensures the connection stability of the connection part and prevents breakage during elastic deformation, thus improving the product's lifespan.

[0028] Furthermore, the connecting cover 110 is installed on the housing 110 by a threaded connection; the inner side of the connecting cover 110 is provided with a threaded post and is fixed to the housing by a threaded connection, which facilitates installation and disassembly.

[0029] Furthermore, the blade mesh component 300 includes a blade mesh frame 320 and a metal mesh cover 330. The blade mesh frame 320 is fixedly connected to the elastic connector 400. The metal mesh cover 330 is fixedly disposed on the inner side of the blade mesh frame 320. The gap between the metal mesh cover 330 and the blade 200 constitutes the working gap. The metal mesh cover 330 is fixed to the middle of the blade mesh frame 320, and the outer periphery of the blade mesh frame 320 and the elastic connector 400 are formed in a secondary manner to ensure that the elastic connector 400 and the blade mesh component 300 are easy to manufacture.
