Description

Technical Field

[0001] This application relates to the field of lint removal equipment technology, and in particular to a lint remover blade and lint remover. Background Technology

[0002] Lint removers, a common tool for garment care, work by using a motor to drive a high-speed rotating blade that works in conjunction with a mesh to cut lint balls. To better conform to the garment and remove lint, current lint removers typically have a curved mesh. However, during operation, the blade can only effectively trim the lint in the central area of ​​the mesh. The curvature at the edges prevents the blade from effectively adhering to the mesh, resulting in a small effective trimming area and low efficiency.

[0003] The above content is only used to assist in understanding the technical solution of the utility model and does not represent an admission that the above content is prior art. Utility Model Content

[0004] In view of the above problems, this utility model proposes a blade for a lint remover, aiming to solve the technical problems of small effective trimming area and low trimming efficiency of lint removers.

[0005] To achieve the above objectives, the lint remover proposed in this utility model includes a blade disc, multiple main blades, and at least one auxiliary blade. The blade disc has a central region and an outer edge region surrounding the central region. The multiple main blades are arranged at intervals around the central axis of the blade disc, and the auxiliary blade is disposed between two adjacent main blades.

[0006] The main blade includes a main blade body and a main cutting edge connected to the top of the main blade body. The main blade body is inserted into the cutter disc, and the main cutting edge is located on one side of the top of the cutter disc, extending from the central region to the outer edge region.

[0007] The auxiliary blade includes an auxiliary blade body and an auxiliary blade edge connected to the top of the auxiliary blade body. The auxiliary blade body is inserted into the cutter disc, and the auxiliary blade edge is located on one side of the top of the cutter disc, corresponding to the outer edge region.

[0008] In one embodiment, there are multiple auxiliary blades, with at least one auxiliary blade between each pair of adjacent main blades, and the multiple main blades and multiple auxiliary blades are arranged radially; the auxiliary cutting edges of the multiple auxiliary blades are all provided corresponding to the outer edge region.

[0009] In one embodiment, the cutter head has a central chip removal through hole at a position between each pair of adjacent main blades and on the side of the auxiliary blades near the central axis.

[0010] In one embodiment, the outer edge region of the cutter head is provided with a plurality of edge chip removal through holes, and the edge chip removal through holes are provided at least between the auxiliary blade and the main blade on the side of the auxiliary blade adjacent to the auxiliary blade.

[0011] In one embodiment, there are multiple auxiliary blades, with at least one auxiliary blade between each pair of adjacent main blades, and the multiple main blades and multiple auxiliary blades are arranged radially; the auxiliary cutting edge of some of the auxiliary blades is disposed corresponding to the outer edge region, and the auxiliary cutting edge of some of the auxiliary blades is disposed corresponding to or adjacent to the central region.

[0012] In one embodiment, the lint remover's blade head further includes a spring piece disposed at the bottom of the blade disc. The spring piece includes multiple main blade connecting parts and multiple auxiliary blade connecting parts. The multiple main blade connecting parts are connected one-to-one to the portions of the main blade bodies that protrude from the bottom surface of the blade disc, and the multiple auxiliary blade connecting parts are connected one-to-one to the portions of the auxiliary blade bodies that protrude from the bottom surface of the blade disc.

[0013] In one embodiment, the plurality of main blade connecting portions and the plurality of auxiliary blade connecting portions are integrally formed.

[0014] In one embodiment, the spring is positioned to avoid the central chip removal through-hole located between two adjacent main blades and the edge chip removal through-hole located between the main blade and the auxiliary blade.

[0015] In one embodiment, the distance from the outer edge of the auxiliary cutting edge to the central axis is greater than the distance from the outer edge of the main cutting edge to the central axis.

[0016] In one embodiment, both the main cutting edge and the auxiliary cutting edge extend into an arc-shaped strip, and the highest point of the auxiliary cutting edge is higher than the highest point of the main cutting edge in the circumferential direction corresponding to the location of the auxiliary cutting edge.

[0017] This utility model also proposes a lint remover, including a main unit, an outer blade net, and a lint remover head as described in any of the above embodiments;

[0018] The main unit includes a housing and a drive mechanism disposed within the housing, the housing having an installation opening;

[0019] The blade of the lint remover is installed at the mounting opening, and the outer blade screen covers the mounting opening. The outer blade screen has multiple lint suction holes, and the inner wall of the outer blade screen is arc-shaped. The main blade and auxiliary blade of the lint remover blade extend in an arc shape to fit the inner wall of the outer blade screen.

[0020] The drive shaft of the drive mechanism is connected to the blade of the lint remover to drive the blade of the lint remover to rotate relative to the outer blade mesh, so that the lint is sucked in through the lint suction hole and cut.

[0021] This utility model of a lint remover adds an auxiliary blade between adjacent main blades, with the auxiliary blade positioned to correspond to the outer edge area. Compared to existing lint removers where only a single main blade covers the entire blade mesh, this auxiliary blade, specifically for the outer edge area, allows for stable shearing with the auxiliary blade. The main and auxiliary blades complement each other, providing a complementary cutting coverage. This allows the lint remover's blade to adapt to changes in the curvature of the curved outer blade mesh, expanding the effective trimming area and improving lint removal efficiency.

[0038] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

Additionally, the meaning of "and / or" throughout the text is to include three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies both A and B.

[0042] In existing technologies, lint removers achieve their cutting function by rotating a moving blade driven by a motor. The outer blade mesh typically employs a curved design to conform to the surface of clothing. Traditional blade heads can only effectively engage with the central area of ​​the outer blade mesh. When the curvature of the outer blade mesh changes at its edges, the main blade cannot form a stable cutting gap with the outer edge, resulting in a significant decrease in edge trimming efficiency and a limited effective trimming area. Therefore, the simple main blade layout of traditional blade heads cannot adapt to the curvature variations of curved blade meshes.

[0043] Based on this, the present invention proposes a blade for a lint remover.

[0044] In this embodiment of the utility model, please refer to Figures 1 to 6 The lint remover's blade head 100 includes a blade disc 110, a plurality of main blades 120 and at least one auxiliary blade 130. The blade disc 110 has a central region 111 and an outer edge region 112 surrounding the central region 111. The plurality of main blades 120 are arranged at intervals around the central axis of the blade disc 110, and the auxiliary blade 130 is disposed between two adjacent main blades 120.

[0045] The main blade 120 includes a main blade body 121 and a main blade edge 122 connected to the top of the main blade body 121. The main blade body 121 is inserted into the cutter head 110, and the main blade edge 122 is located on one side of the top of the cutter head 110. The main blade edge 122 extends from the central region 111 to the outer edge region 112.

[0046] The auxiliary blade 130 includes an auxiliary blade body 131 and an auxiliary blade edge 132 connected to the top of the auxiliary blade body 131. The auxiliary blade body 131 is inserted into the cutter head 110, and the auxiliary blade edge 132 is located on one side of the top of the cutter head 110. The auxiliary blade edge 132 is located corresponding to the outer edge region 112.

[0047] In this embodiment, the cutter head 110 is used to support and mount multiple main blades 120 and auxiliary blades 130. The cutter head 110 is generally flat and plate-shaped. The outer contour shape of the cutter head 110 is adapted to the outer contour shape of the cutter net. Typically, the outer contour of the cutter head 110 is circular to avoid accidental collisions and interference while making the overall structure more compact. For ease of explanation, this document uses a circular cutter head 110 as an example.

[0048] The central region 111 of the cutter head 110 refers to an annular or circular region surrounding the central axis of the cutter head 110 and less than 50% of the total radius of the cutter head 110. The outer edge region 112 of the cutter head 110 refers to the region extending from the outer side of the central region 111 to the outermost edge of the cutter head 110, that is, the outer edge region 112 of the cutter head 110 is an annular region surrounding the central axis of the cutter head 110 and with a radius greater than 50% of the radius of the cutter head 110.

[0049] The number of main blades 120 can be designed and selected according to actual needs. For example, there can be 3 or 6 main blades 120. Generally, to ensure cutting effect, there are usually 6 main blades 120. Multiple main blades 120 are arranged at intervals around the central axis of the cutter head 110, specifically in a uniform distribution. Individual main blades 120 and auxiliary blades 130 can be arranged radially along the cutter head 110. Of course, in some embodiments, the extension directions of the main blades 120 and auxiliary blades 130 can also form a small angle with the radial direction of the cutter head 110, as long as the multiple main blades 120 and auxiliary blades 130 are arranged approximately radially to cooperate with the outer blade net 300 to cut fuzz. The auxiliary blades 130 are positioned between two adjacent main blades 120. To maintain balance, the auxiliary blades 130 can optionally be positioned in the center between two adjacent main blades 120, that is, the central angle between the auxiliary blade 130 and the two adjacent main blades 120 is exactly equal or substantially equal. The number of auxiliary blades 130 can be selected and designed according to actual needs. For example, an auxiliary blade 130 can be set between each pair of adjacent main blades 120, or an auxiliary blade 130 can be set between only some of the main blades 120.

[0050] The main blade 120 and auxiliary blade 130 are metal sheet structures of a certain thickness. The main blade body 121 and auxiliary blade body 131 are the main body parts of the blades. The main blade body 121 and auxiliary blade body 131 can be inserted into the blade disc 110 and fixed at the bottom by a spring clip 140, so that the main blade 120 and auxiliary blade 130 have a certain floating spring in the extension direction of the central axis, which is conducive to better contact with the outer blade net 300 to cut lint when driven to rotate. The main blade 122 and auxiliary blade 132 refer to the blade parts located at the top of the main blade body 121 and auxiliary blade body 131, specifically the sharp edge parts on the blade body used for cutting. The structure and form of the main blade 120 can refer to the existing blade design of the lint remover, and will not be described in detail here. The main blade 122 and auxiliary blade 132 can be implemented using curved metal sheets.

[0051] Understandably, the auxiliary blade 130 is smaller than the main blade 120 so that the extension length of the auxiliary blade 132 is less than that of the main blade 122. The main blade 122 extends continuously from the central region 111 to the outer edge, meaning the main blade 122 is positioned corresponding to both the central and edge regions. This allows the main blade 122 to form a basic cutting surface covering the radius of the blade disc 110. The auxiliary blade 132, on the other hand, is positioned only in the edge region, providing supplementary cutting for areas with varying curvature on the outer edge of the outer blade mesh 300. Therefore, through the synergistic effect of the main blade 120 and the auxiliary blade 130, the cutting area can be expanded from the central region 111 to the edge region, allowing lint balls in both the central and peripheral areas of the outer blade mesh 300 to be effectively captured and cut, greatly increasing the effective cutting area and improving the trimming efficiency of the lint remover.

[0052] The lint remover blade 100 of this utility model adds an auxiliary blade 130 between adjacent main blades 120, so that the auxiliary blade 132 is set corresponding to the outer edge region 112. Compared with the existing lint remover blade 100 which only relies on a single main blade to cover the entire blade net, by adding a dedicated auxiliary blade to the outer edge region 112, the part of the outer blade net 300 corresponding to the outer edge region 112 can form a stable cutting cooperation with the auxiliary blade. The main blade 120 and the auxiliary blade 130 form a complementary cutting coverage, so the lint remover blade 100 can adapt to the outer edge curvature change of the arc-shaped outer blade net 300, expand the effective cutting area, and improve the lint removal efficiency.

[0053] In one embodiment, please refer to Figure 5 and Figure 11 Both the main blade 122 and the auxiliary blade 132 extend into an arc-shaped strip, and the highest point of the auxiliary blade 132 is higher than the highest point of the part of the main blade 122 in the circumferential direction corresponding to the location of the auxiliary blade 132.

[0054] In this embodiment, both the main blade 122 and the auxiliary blade 132 are arc-shaped strips to better adapt to the arc-shaped outer blade net 300. The portion of the main blade 122 corresponding to the central area is defined as the central blade, and the portion of the main blade 122 corresponding to the outer edge area 112 is defined as the outer edge blade. When the auxiliary blade 132 is positioned corresponding to the outer edge area 112, the highest point of the auxiliary blade 132 is higher than the highest point of the auxiliary blade 132 portion. This allows the auxiliary blade 132 to better cooperate with the portion corresponding to the edge area of ​​the outer blade net 300, thus forming a stable shearing gap between the auxiliary blade 130 and the outer edge of the outer blade net 300, while the main blade 120 can form a stable shearing gap with the central portion of the outer blade net 300. In this way, the auxiliary blade 130 and the main blade 120 form a complementary cutting coverage, thereby expanding the effective trimming range and enabling the lint in both the central and edge areas of the outer blade net 300 to be effectively captured and trimmed, significantly improving the cutting efficiency.

[0055] In one embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, multiple auxiliary blades 130 are provided, with at least one auxiliary blade 130 between each pair of adjacent main blades 120. The multiple main blades 120 and multiple auxiliary blades 130 are arranged radially; the auxiliary cutting edges 132 of the multiple auxiliary blades 130 are all positioned corresponding to the outer edge region 112. By providing at least one auxiliary blade 130 between each pair of adjacent main blades 120, and ensuring that the auxiliary cutting edges 132 of the multiple auxiliary blades 130 are all positioned corresponding to the outer edge region 112, the multiple auxiliary blades 130 are arranged around the central axis and evenly distributed among the multiple main blades 120. Therefore, when the cutter head rotates, the multiple auxiliary cutting edges 132 can form a shearing engagement with the inner wall surface of the outer blade net 300 corresponding to the edge region of the cutter disc 110, further improving the lint shearing efficiency. Optionally, six main blades 120 and six auxiliary blades 130 are provided, so that the multiple main blades 120 and the multiple auxiliary blades 130 are arranged alternately.

[0056] Further, please refer to Figures 1 to 4 , Figure 6The cutter head 110 has a central chip removal hole 113 located between each pair of adjacent main blades 120 and on the side of the auxiliary blade 130 near the central axis. This central chip removal hole 113 can be located in the central region 111 of the cutter head 110, or at the junction of the central region 111 and the edge region. The central chip removal hole 113 is a hole penetrating the cutter head 110 in the thickness direction. The shape of the central chip removal hole 113 can be various, such as circular, rectangular, elliptical, fan-shaped, polygonal, etc., and is not specifically limited here. By opening the central chip removal hole 113 penetrating the cutter head 110 on the inner side of adjacent main blades 120 and auxiliary blades, lint and debris generated during the cutting process can be discharged. When the main blade 120 and the auxiliary blade 130 work together to cut, the chips move towards the central region 111 along the gap between two adjacent main blade sections 121 or between the main blade section 121 and the auxiliary blade section 131, and are discharged from the bottom of the cutter head 110 through the central chip removal hole 113, preventing chips from accumulating in the central region 111 of the cutter head 110 and increasing cutting resistance. Furthermore, the position of the central chip removal hole 113 avoids the cutting trajectory of the main blade section 122 and the auxiliary blade section 132, ensuring that the chip removal process does not affect cutting efficiency.

[0057] Furthermore, the outer edge region 112 of the cutter head 110 is provided with a plurality of edge chip removal through holes 114, at least between the auxiliary blade 130 and the main blade 120 on the side of the auxiliary cutting edge portion 132 adjacent to the auxiliary blade 130. The edge chip removal through hole 114 refers to a hole that penetrates the cutter head 110 in the thickness direction. The shape of the edge chip removal through hole 114 can be various, such as circular, rectangular, elliptical, fan-shaped, polygonal, etc., and is not specifically limited here.

[0058] In practice, the auxiliary blade portion 132 is bent to one side relative to the auxiliary blade body portion 131, and the main blade portion 122 bends in the same direction as the auxiliary blade portion 132, for example, both bend clockwise or both bend counterclockwise. The motor drives the cutter head to rotate towards the side where the auxiliary blade portion 132 is bent. Therefore, the lint balls cut by the auxiliary blade 130 will fall between the auxiliary blade 130 and the main blade 120 adjacent to (i.e., facing) the auxiliary blade portion 132. Therefore, at least one edge chip removal hole 114 is provided between the auxiliary blade and the main blade 120 adjacent to the auxiliary blade portion 132 of the auxiliary blade 130, so that the chips cut by the auxiliary blade 130 can be discharged from the cutter head 110 through the edge chip removal hole 114, avoiding the accumulation of chips in the edge area during the cutting process. It is understood that the debris between the auxiliary blade 130 and another main blade 120 (i.e., the main blade 120 with the auxiliary cutting edge 132 facing away from the auxiliary blade 130) can be discharged through the central chip discharge hole 113 by gradually moving to the central region 111. Of course, in some embodiments, one of these edge chip discharge holes 114 can be provided between the auxiliary blade 130 and each of the two adjacent main blades 120 to improve chip removal efficiency.

[0059] In another embodiment, multiple auxiliary blades 130 are provided, with at least one auxiliary blade 130 between every two adjacent main blades 120. The multiple main blades 120 and multiple auxiliary blades 130 are arranged radially. The auxiliary cutting edge portion 132 of some auxiliary blades 130 is provided corresponding to the outer edge region 112, and the auxiliary cutting edge portion 132 of some auxiliary blades 130 is provided corresponding to or adjacent to the central region 111. That is, some auxiliary blades 130 are provided in the central region 111, and some auxiliary blades 130 are provided in the edge region. In this way, the auxiliary blades 130 provided in the edge region can supplement the cutting of the outer edge curvature change area of ​​the outer blade net 300, while the auxiliary blades 130 provided in the central region 111 increase the cutting surface of the central region 111. This allows the portion of the outer blade net 300 corresponding to the outer edge region 112 to form a stable shearing cooperation with the auxiliary blade. The main blades 120 and auxiliary blades 130 cooperate to cut the central region 111, forming a complementary cutting coverage, further expanding the effective trimming area and improving the efficiency of lint removal. To ensure uniform cutting, the auxiliary blades 130 corresponding to the outer edge region 112 and the auxiliary blades 130 corresponding to the central region 111 may be arranged alternately in the circumferential direction.

[0060] In one embodiment, such as Figures 3 to 6 , Figure 8As shown, the lint remover's blade head 100 also includes a spring piece 140 located at the bottom of the blade disc 110. The spring piece 140 includes multiple main blade connecting parts 141 and multiple auxiliary blade connecting parts 142. The multiple main blade connecting parts 141 are connected one-to-one to the portions of multiple main blade body parts 121 that protrude from the bottom surface of the blade disc 110, and the multiple auxiliary blade connecting parts 142 are connected one-to-one to the portions of multiple auxiliary blade body parts 131 that protrude from the bottom surface of the blade disc 110.

[0061] In this embodiment, the spring sheet 140 refers to an elastic sheet-like support structure, which can be made by stamping spring steel sheets, and is used to elastically support the main blade 120 and the auxiliary blade 130. The spring sheet 140 covers the bottom area of ​​the cutter head 110, and can be fixedly connected to the bottom of the cutter head 110 by means of plugging, riveting, etc. By connecting multiple main blades 120 and multiple auxiliary blades 130 through the spring sheet 140, the multiple main blades 120 and multiple auxiliary blades 130 can bounce slightly in the extension direction of the central axis under the elastic force of the spring sheet 140, so as to facilitate better contact between the main blades 120 and auxiliary blades 130 and the outer blade net 300 when the cutter head is driven to rotate, so as to cut fuzz balls. That is, during the rotation of the cutter head, the spring 140 can absorb the vibration of multiple main blades 120 and multiple auxiliary blades 130 through elastic deformation, while maintaining the relative position of each blade stable, thus achieving dynamic stability of the blade. Under high-speed rotation conditions, it can automatically compensate for assembly gaps and avoid blade misalignment due to vibration.

[0062] For ease of explanation, the portion of the main blade body 121 extending through the bottom surface of the cutter head 110 is defined as the main blade mounting portion, and the portion of the auxiliary blade body 131 extending through the bottom surface of the cutter head 110 is defined as the auxiliary blade mounting portion. The main blade connecting portion 141 is used to connect with the main blade body 121, and the auxiliary blade connecting portion 142 is used to connect with the auxiliary blade body 131. The main blade connecting portion 141 and the main blade mounting portion can be flexible cantilever structures, and are fixed to the blade by elastic clamping, snap-fitting, or plugging methods. The auxiliary blade connecting portion 142 and the auxiliary blade mounting portion can be fixed by elastic clamping, snap-fitting, or plugging methods. Optionally, the main blade connecting part 141 includes a first insert strip and a first snap-fit ​​part that are circumferentially opposite each other. The first insert strip is inserted into the insertion hole of the main blade mounting part, and the first snap-fit ​​part engages radially with a protrusion of the main blade mounting part. The auxiliary blade connecting part 142 includes a second insert strip and a second snap-fit ​​part that are circumferentially opposite each other. The second insert strip is inserted into the insertion hole of the auxiliary blade mounting part, and the second snap-fit ​​part engages radially with a protrusion of the auxiliary blade mounting part. The first snap-fit ​​part and the second snap-fit ​​part can specifically adopt a U-shaped buckle. In this way, the installation of the main blade connecting part 141 and the main blade 120 of the spring 140, as well as the auxiliary blade connecting part 142 and the auxiliary blade 130 of the spring 140, is more reliable and convenient.

[0063] Furthermore, multiple main blade connecting parts 141 and multiple auxiliary blade connecting parts 142 are integrally formed. By forming a continuous spring sheet 140 body from the main blade connecting parts 141 and the auxiliary blade connecting parts 142 through an integral forming process, the overall structural strength of the spring sheet 140 is improved. At the same time, when the blade head rotates at high speed, the spring sheet 140 can synchronously transmit driving force to the auxiliary blade 130 and the main blade 120. Meanwhile, the elastic deformation of the spring sheet 140 as a whole absorbs the impact energy generated when the blade comes into contact with the lint ball.

[0064] In conjunction with the above embodiment having a central chip removal through-hole 113 and an edge chip removal through-hole 114, please further refer to... Figure 3 , Figure 4 , Figure 6 and Figure 8 The spring 140 is positioned to avoid the central chip removal hole 113 located between two adjacent main blades 120 and the edge chip removal hole 114 located between the main blade 120 and the auxiliary blade 130. This ensures that chip removal from the central chip removal hole 113 and the edge chip removal hole 114 is normal, preventing lint and debris discharged from these holes from clogging or becoming entangled in the spring 140. This, in turn, prevents excessive friction on the cutting head from causing uneven rotation and resulting in abnormal noise.

[0065] In one embodiment, such as Figure 2 As shown, the distance from the outer edge of the auxiliary blade portion 132 to the central axis is greater than the distance from the outer edge of the main blade portion 122 to the central axis. That is, in the circumferential direction around the central axis, the outer edge of the auxiliary blade portion 132 extends beyond the outer edge of the main blade portion 122. Specifically, the outer edge of the auxiliary blade portion 132 can be set to extend 1-5 mm beyond the outer edge of the main blade portion 122. By extending the extension range of the auxiliary blade portion 132, the effective cutting area of ​​the blade edge region can be expanded, further increasing the overall trimming area of ​​the lint remover and improving trimming efficiency.

[0066] This utility model also proposes a lint remover, such as Figures 9 to 11 As shown, the lint remover includes a main unit 200, an outer blade net 300, and a lint remover head 100. The specific structure of the lint remover head 100 is as described in the above embodiment. The main unit 200 includes a housing 210 and a drive mechanism 220 disposed within the housing 210. The housing 210 has an installation opening 211.

[0067] The blade 100 of the lint remover is installed at the mounting opening 211, and the outer blade screen 300 covers the mounting opening 211. The outer blade screen 300 is provided with multiple lint suction holes 310, and the inner wall surface of the outer blade screen 300 is arc-shaped. The main blade 122 and the auxiliary blade 132 of the blade 100 of the lint remover extend in an arc shape to adapt to the inner wall surface of the outer blade screen 300.

[0068] The drive shaft of the drive mechanism 220 is connected to the cutter head 100 of the lint remover to drive the cutter head 100 of the lint remover to rotate relative to the outer blade screen 300, so that the lint is sucked in through the lint suction hole 310 and cut.

[0069] Since this lint remover adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.

[0070] The outer blade mesh 300 has an arc-shaped inner wall, allowing it to be slightly curved and better conform to the surface of clothing. The arc-shaped extension of the main blade 122 and auxiliary blade 132 means that the top surface of the cutting portion of the blade is arc-shaped. The drive mechanism 220 can be a drive motor. The drive shaft and the blade disc 110 of the blade head can be fixedly connected by plugging, threading, or keyway to ensure stable rotation of the blade head by the drive mechanism 220. The outer blade mesh 300 has multiple lint suction holes 310. The shape and arrangement of the lint suction holes 310 can vary and are not specifically limited here. The outer blade mesh 300 can be detachably connected to the housing 210 via a cover to facilitate cleaning of the blade head and lint debris at the installation opening 211. The detachable connection method is not specifically limited here; for example, snap-fit ​​or threaded connections can be used. It should be noted that the cutting efficiency can be improved by equipping the main blade 120 with an impeller function or by additionally setting an impeller, so that the blade head can attract lint balls when rotating and blow the cut lint balls into the chip discharge hole. The relevant structure of the adsorption function can adopt existing designs, and no specific limitation is made on the relevant structure of the adsorption function here.

[0071] Specifically, the arc-shaped extension trajectories of the main and auxiliary cutting edges of the blade head form a matching gap with the arc-shaped inner wall surface of the outer blade net 300. When the drive mechanism 220 drives the blade head to rotate, the main and auxiliary cutting edges maintain a uniform cutting distance in both the central region 111 and the edge region near the outer blade net 300. Wool balls enter the shearing area between the blade head and the outer blade net 300 through the suction hole of the outer blade net 300. During rotation, the main and auxiliary cutting edges cut the wool balls along the arc-shaped path, covering the complete trimming area from the center to the edge.

[0072] This solution, through the matching design of the arc-shaped blades of the main blade 120 and the auxiliary blade 130 with the arc-shaped blade net, enables the blade to maintain an effective cutting distance in the edge area of ​​the blade net. It achieves full fit between the blade head and the outer blade net 300 in the central area 111 and the edge area, expands the effective trimming area, and enables the lint remover to evenly process lint in areas with different curvatures on the surface of clothing, significantly improving trimming efficiency.

[0073] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
