Description

Technical Field

[0001] This utility model relates to a cleaning brush, and more particularly to a multifunctional cleaning brush. Background Technology

[0002] Cleaning brushes, widely used in daily life, play a vital role in cleaning homes, offices, and various public areas due to their strong cleaning power and ease of use. Whether sweeping dust and stains from the floor or wiping the surfaces of cabinets, doors, windows, and other furniture, cleaning brushes can quickly remove dirt and grime through effective contact between their bristles and the surface being cleaned, creating a clean environment. However, with the increasing diversification and sophistication of cleaning needs, existing cleaning brushes have gradually revealed several shortcomings, failing to meet the various requirements of actual use scenarios. Firstly, their hand comfort and anti-slip performance are inadequate. Current cleaning brush designs often focus on the basic grip shape of the handle, neglecting the impact of material selection and surface treatment on anti-slip performance. During use, when hands are sweaty or come into contact with water or cleaning agents, the handle easily becomes slippery, making it difficult for users to hold the brush securely. This not only increases the difficulty of cleaning but also may cause the brush to slip and fall, resulting in damage or accidental injury to surrounding people and objects. Secondly, the bristle structure is too simple, leaving cleaning blind spots. Most cleaning brushes on the market currently have bristles arranged in a neat, flat pattern. This design is effective for cleaning large, flat surfaces. However, when encountering irregular areas such as corners, furniture crevices, and gaps, the neatly arranged bristles cannot effectively reach these narrow spaces, making it difficult to thoroughly remove dirt. This results in incomplete cleaning, leaving unsanitary areas and affecting the overall cleaning quality. In conclusion, existing cleaning brushes have significant shortcomings in terms of anti-slip performance and cleaning adaptability. There is an urgent need to develop a multi-functional cleaning brush with better anti-slip properties and adaptability to various cleaning scenarios to meet people's growing cleaning needs.

[0003] The technical problem to be solved by this utility model is to provide a multifunctional cleaning brush.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0005] A multifunctional cleaning brush includes a handle and a brush head, which are integrally formed by injection molding. The handle and brush head are set at an angle of 10-30°, and a protrusion is provided at the connection between them. The tail end of the handle is semi-olive-shaped and has a through hanging hole. The upper part of the handle has anti-slip texture. The lower end of the handle is implanted with bristles by a bristle implantation machine, and the two sides of the bristles are set outward.

[0006] The brush handle and brush head are set at a 20° angle.

[0007] The bottom of the brush handle is open.

[0008] The bristles can be made of existing materials, such as nylon or bristle.

[0009] The brush handle and brush head can be made of plastic.

[0010] The anti-slip texture is made using laser engraving.

[0011] The manufacturing process of this cleaning brush includes the following steps:

[0012] 1. The manufacturing of the multi-functional cleaning brush begins with the strict selection and pretreatment of raw materials. The brush handle and head are made of high-density polyethylene (HDPE) plastic granules, which need to be dried at 80-90℃ for 4-6 hours to ensure a moisture content ≤0.2% to avoid air bubbles during injection molding. The bristles are selected according to requirements: nylon (PA612) with a diameter of 0.18-0.22mm and a length of 15-20mm, and pig bristles with a diameter of 0.25-0.30mm and a length of 18-22mm, both requiring degreasing or bleaching treatment. The mold design adopts a two-plate mold structure, with the parting line located below the protrusion at the connection between the brush handle and brush head. It is equipped with a slanted ejector mechanism (angle 12-15°) and a conformal water channel (diameter 8mm) to ensure smooth demolding and uniform cooling. The surface roughness of the cavity needs to be controlled within Ra≤0.8μm, with a tolerance of ±0.02mm, to ensure that the finished product's angle deviation is ≤±1°. 2. In the injection molding process, an injection molding machine with a clamping force of 150-200 tons is selected. The barrel temperature is set in sections: 180-200℃ for the rear section, 210-230℃ for the middle section, and 230-250℃ for the front section. The mold temperature is 60-80℃, the injection pressure is 80-100MPa, the holding pressure is 60-70MPa, the cooling time is 15-20 seconds, and the total cycle time is 35-45 seconds per piece. After molding, an automatic deflashing machine is used to remove the flash from the parting surface with rotating blades (speed 2000-3000rpm) at a feed rate of 0.1-0.2mm / pass to ensure a smooth surface. Subsequently, a coordinate measuring machine (CMM) is used to check the angle between the brush handle and the brush head, with an allowable deviation of ±0.5°. Defective products are reworked or scrapped. 3. The anti-slip texture is engraved using a CO2 laser with a power of 30-50W and a spot diameter of 0.1-0.2mm. A galvanometer scanning system (speed 5000-8000mm / s) is used to engrave a texture 0.1-0.2mm deep and 0.3-0.5mm wide on the brush handle surface. The engraving is completed in 2-3 passes, each 0.05-0.1mm deep. After completion, ultrasonic cleaning removes any residue. The bristles are implanted using a fully automatic high-speed bristle implantation machine, with drilling holes 1.8-2.2mm in diameter and 8-10mm deep. Nylon bristles are arranged in a checkerboard pattern (hole spacing 3-4mm, 20-30 bristles per hole), while bristle bristles are arranged in a houndstooth pattern (hole spacing 2.5-3.5mm, 15-20 bristles per hole). After implantation, the bristle height deviation was measured using a laser rangefinder to ensure it was ±0.5mm, and the bristle density was verified by weighing (nylon ≥15g / 100cm², bristles ≥12g / 100cm²). 4. Post-processing includes deburring and cleaning: A 3mm diameter grinding head (10000-15000rpm) was used to remove burrs around the implantation holes. The grinding head was 2-3 seconds per hole. The finished product was then immersed in a cleaning solution with a pH of 7-8, ultrasonically cleaned for 10 minutes, and then dried with hot air at 80-90℃.Performance testing covers appearance, dimensions, and function: Appearance must be free of burrs and cracks, and the anti-slip texture must be clear; dimensions must meet the requirements of an angle of 20°±0.5° and a bristle height deviation of ±0.5mm; functional testing includes bristle pull-out force ≥5N / bristle (ASTM D5758 standard) and anti-slip texture friction coefficient ≥0.6 (ASTM D1894 standard). Defective products must be repaired or discarded. 5. Finished products are individually packaged in PE plastic bags, with 50-100 pieces per corrugated cardboard box filled with shock-absorbing foam to prevent damage during transportation. Storage environment requirements: temperature 10-30℃, relative humidity ≤60%, avoid direct sunlight to prevent material aging.

[0013] The beneficial effects of this utility model are:

[0014] This multi-functional cleaning brush features a scientifically designed structure. The handle and brush head are angled at 20° with a raised connection point, and the bristles flare outwards on both sides. This unique shape allows for better contact with the cleaning surface, effectively expanding the cleaning area and improving cleaning efficiency while reducing the user's hand strain and labor intensity. Furthermore, the semi-olive-shaped end of the handle with a hanging hole facilitates convenient storage and saves space. In terms of manufacturing, strict raw material selection and pretreatment, along with precise control over injection molding, laser engraving, and bristle implantation processes, ensure high-precision molding and high-quality assembly of all components. The anti-slip texture, laser-engraved, not only enhances anti-slip performance but also improves the product's appearance. The meticulous processing and rigorous testing of the bristles guarantee cleaning effectiveness and lifespan, comprehensively improving the product's quality and market competitiveness.

Storage environment requirements: temperature 10-30℃, relative humidity ≤60%, avoid direct sunlight to prevent material aging.

[0028] The implementation principle of this utility model is based on the comprehensive application of its structural design and material properties. Firstly, the brush handle 1 and brush head 2 are set at a 20° angle and integrally molded using a mold. This angle design conforms to ergonomics, allowing users to operate flexibly in different scenarios. Simultaneously, the protrusion 3 at the connection point enhances structural strength and prevents breakage during use. The end of the brush handle 1 is semi-olive-shaped and has a hanging hole 4 for convenient hanging and storage. The lower opening 7 design reduces weight and saves material. The upper anti-slip texture 5 is laser-engraved to a depth of 0.1-0.2mm, effectively increasing friction and preventing slippage. The bristles 6 are made of nylon or bristle material, with both sides opening outwards to expand the cleaning area and improve cleaning efficiency. Their diameter and length are optimized according to material properties to ensure a balance between durability and cleaning power. In terms of manufacturing process, high-density polyethylene (HDPE) plastic granules are selected as raw materials. After drying at 80-90℃, the moisture content is ≤0.2% to avoid air bubbles in the injection molding. The bristles 6 are degreased or bleached to ensure the bonding strength with the brush handle 1. The mold design adopts a two-plate mold structure, with the parting line located below the protrusion 3. The inclined ejector mechanism (angle 12-15°) and conformal water channel (diameter 8mm) ensure smooth demolding and uniform cooling. The surface roughness of the cavity Ra is ≤0.8μm with a tolerance of ±0.02mm, ensuring that the angle deviation of the finished product is ≤±1°. In the injection molding process, segmented temperature control (rear section 180-200℃, middle section 210-230℃, front section 230-250℃) and pressure control (injection pressure 80-100MPa, holding pressure 60-70MPa), combined with a 15-20 second cooling time, ensures the stable molding quality of the brush handle 1 and brush head 2. An automatic deburring machine removes burrs from the parting surface at a speed of 2000-3000 rpm. A coordinate measuring machine detects angular deviations of ±0.5°. Defective products are reworked or scrapped to ensure product consistency. Post-processing and inspection further enhance performance. The anti-slip texture 5 is engraved in 2-3 passes using a CO2 laser, each pass being 0.05-0.1mm deep to avoid material ablation. The bristle 6 is implanted using a fully automatic high-speed bristle implantation machine. Nylon bristles are arranged in a checkerboard pattern (hole spacing 3-4mm, 20-30 bristles per hole), while bristle bristles are arranged in a houndstooth pattern (hole spacing 2.5-3.5mm, 15-20 bristles per hole). A laser rangefinder detects height deviations of ±0.5mm, and density is verified by weighing (nylon ≥15g / 100cm², bristle ≥12g / 100cm²). Electric grinders remove burrs from the bristle pores, and ultrasonic cleaning combined with hot air drying ensures cleanliness. Performance tests include bristle pull-out force ≥5N / bristle (ASTM D5758 standard) and anti-slip texture friction coefficient ≥0.6 (ASTM D1894 standard). The final product is individually packaged in PE plastic bags and transported in corrugated cardboard boxes for shock protection. It is stored in an environment with a temperature of 10-30℃ and humidity ≤60% to extend its service life.
