Description

Technical Field

[0001] This utility model relates to the technical field of carpet trimming equipment, specifically a vacuum-type carpet trimming and hair removal device. Background Technology

[0002] Carpets, as a common flooring material, are widely used in homes, offices, hotels, and exhibition venues. During use, factors such as foot traffic, pulling, and friction can easily cause loose threads or lint buildup, affecting not only aesthetics but also durability and safety. Therefore, regular trimming and cleaning of carpets are essential maintenance procedures.

[0003] Existing carpet trimming devices primarily employ mechanical rotating blades or roller cutting structures, using manual or semi-automatic methods to trim surface threads. However, these structures generally suffer from the following technical problems: The separation of trimming and cleaning functions makes operation cumbersome: Most trimming equipment only has the function of cutting and cannot complete dust collection and cleaning at the same time. A vacuum cleaner is required to assist in the operation, which increases the labor cost and reduces the overall work efficiency.

[0004] Low dust collection path efficiency and easy dust residue: In some devices with dust collection function, dust is often collected through simple guide pipes or closed chambers. However, due to the lack of a high-efficiency graded filtration structure, dust is often discharged back into the system or the filter is clogged, which affects suction power and equipment life.

[0005] Poor trimming stability, prone to accidental damage or blade skipping: Existing devices mostly use straight blades or toothed blades, and the contact structure with the carpet is simple, lacking flexible adjustment or stable contact mechanism, resulting in insufficient cutting accuracy and the risk of damaging the carpet fiber structure.

[0006] In summary, existing carpet trimming and hair removal equipment still has significant technical bottlenecks in terms of integration, trimming efficiency, dust collection and purification capabilities, and structural convenience. There is an urgent need for a new type of device that integrates dust collection and trimming, has a compact structure, is easy to use, has high dust collection efficiency, and is easy to clean and maintain in order to solve the above problems.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a vacuum-type carpet trimming and hair removal device.

[0030] Combination Figures 1-5 As shown, the present invention provides a vacuum-type carpet trimming and hair removal device, including a movable body 100, a vacuuming component 200, and a trimming component 300 fixed to one side of the movable body 100.

[0031] The mobile body 100 is used for the support and movement of the overall structure. A fan motor 120 is embedded in its surface. The end of the fan motor 120 is provided with a centrifugal impeller 121 for outputting airflow. The fan motor 120 is detachably installed inside the mobile body 100 and is electrically connected to the control system through electrode sliders provided on its surface.

[0032] To enable power supply and control, a power supply box 110 is provided on the surface of the mobile unit 100. The power supply box 110 has a detachable installation structure. The bottom surface of the mobile unit 100 is equipped with multiple casters for smooth movement of the device on the carpet surface. The mobile unit 100 contains a control component, including a wireless remote control module for remotely controlling the start / stop and parameter adjustment of the fan motor 120 and the trimming component 300.

[0033] The dust collection assembly 200 includes a dust box 210, a filter cartridge 220, and a fiber filter 230. The filter cartridge 220 is fixedly installed inside the dust box 210 and is sealed to the outer periphery of the fiber filter 230. A filter screen 221 is fitted onto the surface of the filter cartridge 220. The filter screen 221 has a ring structure and several evenly distributed filter holes on its surface for primary filtration. The fiber filter 230 is used for secondary fine filtration. One end of the fiber filter 230 is connected to the air inlet of the fan motor 120, and the other end is fitted to the inner side of the filter cartridge 220, thereby forming a closed airflow path.

[0034] A cover 211 is movably connected to the surface of the dust box 210, facilitating the operator to disassemble and clean the collected lint and dust. A grid hole is provided between the fan motor 120 and the fiber filter 230, located at the connection between the fan motor 120 and the movable body 100, to improve gas exhaust efficiency.

[0035] Specifically, the fan motor 120 and the mobile body 100 have grid holes on their surfaces located on the outer periphery of the centrifugal impeller 121 for ventilation and air exhaust.

[0036] The trimming assembly 300 mainly includes a roller housing 310, a rotating roller 320, an anvil strips 330, and a drive structure. Several rotating rollers 320 are provided on the bottom surface of the roller housing 310, with the bottom surface of each roller 320 slightly protruding from the bottom surface of the roller housing 310 to maintain contact with the carpet surface. Inside each rotating roller 320 is a roller frame 321, which is a cylindrical skeleton structure. Multiple spirally distributed cutting strips 322 are evenly distributed on the outside of the roller frame 321. These cutting strips 322 and the anvil strips 330 fixed to the bottom surface of the roller housing 310 form a shearing engagement structure.

[0037] Specifically, the bottom surface of the roller shell 310 is provided with a plurality of rotating rollers 320, and the bottom surface of the rotating rollers 320 protrudes outward from the bottom surface of the roller shell 310.

[0038] The two ends of the rotating roller 320 are driven by the shaft motor 311, which is fixedly installed at both ends of the roller housing 310 and is used to drive the rotating roller 320 to rotate at a set angular velocity to realize high-frequency hair cutting action.

[0039] In addition, in order to collect the trimmed shavings in a timely manner, the surface of the roller shell 310 is provided with a dust collection pipe 312. One end of the dust collection pipe 312 is connected to the dust box 210, and the other end is arranged close to the cutter bar 322, so that the debris generated during the cutting process can be directly sucked into the dust box 210.

[0040] In practical implementation, when the operator starts the control system via remote control, the fan motor 120 begins to rotate, driving the centrifugal impeller 121 to generate negative pressure and form an airflow channel. Air flows through the filter screen 221 and the fiber filter screen 230 to form a two-stage filtration, blocking dust and lint, while clean air is discharged from the grid holes outside the fan motor 120. At the same time, the shaft motor 311 drives the rotating roller 320 to rotate, causing the cutting strip 322 to cut the loose threads on the carpet surface. The resulting debris is promptly sucked into the dust box 210 through the dust collection pipe 312, realizing the linkage function of trimming and vacuuming.

[0041] To further improve structural maintainability, the fiber filter 230 is provided with fasteners at both ends for connection to the filter cartridge 220 and the fan motor 120, respectively. The fasteners enable detachable connection between the fiber filter 230, the filter cartridge 220 and the fan motor 120, facilitating daily maintenance and replacement. Working principle and usage process of this utility model: This utility model provides a vacuum-type carpet trimming and hair removal device, which mainly consists of a mobile body, a vacuuming component and a trimming component. It combines a cutting and adsorption linkage structure to achieve simultaneous trimming and cleaning of carpet surface stray hairs.

[0042] Before use, the operator can power on the power box via the wireless remote control module, activating the control system inside the mobile unit 100. This starts the fan motor 120, causing the centrifugal impeller 121 to rotate and generate negative pressure suction, forming a suction airflow channel from the end of the dust box 210 to the inside of the mobile unit 100. This channel undergoes two stages of filtration: first through the filter screen 221, then through the fiber filter screen 230, effectively blocking lint and dust particles to ensure the cleanliness of the exhaust gas.

[0043] At the same time, the trimming component 300 starts to operate under the drive of the shaft motor 311, which drives the internal roller frame 321 to rotate, and drives several spirally arranged cutting strips 322 to cooperate with the fixed anvil strips 330 below to form a shearing structure, which precisely cuts off the messy fibers such as lint and thread produced on the carpet surface.

[0044] To improve dust collection efficiency, the dust collection pipe 312 on the roller shell 310 is connected to the dust box 210. The debris and dust generated during the trimming process will be directly sucked into the dust box, filtered by the filter cartridge 220 and the fiber filter screen 230, and then discharged through the fan motor 120.

[0045] After trimming, the operator can open the dust box 210 through the cover 211 to empty the collected lint and impurities for easy daily maintenance and cleaning. Meanwhile, since the filter cartridge, fiber filter, and fan motor are all detachable, they can be easily replaced or washed for cleaning.

[0046] In summary, this utility model, through its combined cutting and adsorption structure, not only achieves efficient trimming of stray hairs on the carpet surface but also effectively improves cleaning efficiency and ease of use, making it suitable for the maintenance of various carpets in homes, hotels, exhibition halls, and other settings.
