Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically to an industrial vacuum cleaner nozzle. Background Technology

[0002] In modern industrial production systems, bulk materials are widely packaged using ton bags as containers during warehousing, transportation, and processing. Ton bags are typically woven from high-strength polypropylene (PP) or polyethylene (PE), and their surfaces have numerous tiny gaps and pores, making them highly susceptible to dust particle accumulation. In industries such as chemicals, food, pharmaceuticals, and building materials, dust pollution not only affects product quality but can also lead to safety and hygiene problems such as explosions, allergies, or environmental pollution. Therefore, thorough and efficient cleaning of ton bag surfaces is an indispensable and crucial step in the production process.

[0003] Existing vacuum cleaner nozzles exhibit significant limitations when handling such tasks. Their round or rectangular nozzles cannot tightly conform to the flexible curved surface of the ton bag, leading to air leakage at the edges and reducing effective suction power. Under high negative pressure operating conditions, fine dust easily accumulates rapidly on the inner wall of the nozzle, causing channel blockage and affecting continuous operation efficiency. The problem of secondary dust caused by air disturbance during vacuuming is serious, with some dust spreading into the surrounding environment without being sucked in, forming new sources of pollution. Due to the coarse texture of the ton bag surface, dust often embeds deep in the woven gaps, and ordinary nozzles, lacking sufficient local negative pressure concentration capacity, cannot effectively remove deep-seated deposits. Furthermore, they generally suffer from complex structures, high costs, and inconvenient maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide an industrial vacuum cleaner nozzle to solve the problems of low fit, poor cleaning efficiency, easy clogging, serious dust generation and high maintenance cost in the existing technology for dust removal of flexible packaging materials such as ton bags, so as to achieve efficient, reliable and low-cost industrial dust cleaning.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An industrial vacuum cleaner nozzle includes a nozzle body and a connecting part that connects to the vacuum cleaner's suction pipe. One end of the connecting part is a cylindrical interface section, and the other end is a conical transition section. The nozzle body is generally flat and triangular, with a wide suction port at the front end and a tapered transition section at the rear end connected to the conical transition section of the connecting part via a gradually narrowing transition surface, forming a streamlined structure. This facilitates airflow convergence and pressure distribution optimization, guides airflow smoothly into the suction channel, reduces eddies and energy loss, and improves suction transmission efficiency.

[0006] Furthermore, multiple vent holes are provided on one flat surface of the nozzle body. These vent holes are symmetrically and evenly arranged along the width of the suction port and penetrate the side wall of the nozzle body. They are used to introduce compensating airflow to balance the negative pressure inside the suction port, prevent the nozzle from adhering to soft surfaces or causing local blockages, and simultaneously form a surrounding air curtain to suppress dust during operation.

[0007] The vents introduce a small amount of external air to create a "compensating airflow," balancing the negative pressure inside the nozzle and preventing it from becoming stuck on soft surfaces or causing localized blockages due to excessive vacuum. Simultaneously, the compensating airflow creates a slight positive pressure zone around the nozzle, inhibiting dust from spreading outwards and thus suppressing dust.

[0008] Furthermore, the vent can be configured as a conical vent with a large inlet and a small outlet to optimize the airflow direction and reduce turbulence.

[0009] Furthermore, the suction port is generally flat and rectangular or trapezoidal, wide at the front end and gradually narrowing towards the rear, connecting with a conical transition section. The flat shape can increase the contact area with the surface of the ton bag, improve the fit, and concentrate the airflow in the narrow gap area to enhance the local adsorption force.

[0010] Furthermore, the cylindrical interface section is equipped with a standard threaded interface or a quick-connect snap-fit ​​structure to achieve a detachable connection with the industrial vacuum cleaner's exhaust pipe, and is compatible with mainstream equipment interfaces.

[0011] Furthermore, a detachable cleaning strip is provided at the front edge of the suction port, which is fixed by adhesive or magnetic attraction. The cleaning strip is made of a flexible and wear-resistant material (such as polyurethane elastomer, silicone rubber or Teflon-coated fabric), and its length is slightly less than the width of the suction port. It is used to scrape off stubborn dust on the surface and loosen the attachments embedded deep in the weave gaps during the movement of the suction nozzle.

[0012] Furthermore, the surface of the nozzle body is matte-finished or coated with an antistatic coating to reduce dust adhesion.

[0013] Furthermore, the industrial vacuum cleaner nozzle is integrally molded from engineering plastic using 3D printing technology.

[0014] Furthermore, the engineering plastic is ABS, PC, or nylon.

[0015] Furthermore, the industrial vacuum cleaner nozzle can be used for dust removal of flexible packaging materials such as ton bags and canvas.

[0016] Beneficial effects: The flat triangular structure combined with the tapered bevel design allows the nozzle to better adapt to the slight undulations of soft surfaces such as ton bags, reducing air leakage and ensuring effective negative pressure applied to the target area; the flat suction port concentrates airflow in the crevices, and combined with the mechanical scraping action of the front cleaning strip, it can effectively remove deeply attached dust; the balanced airflow introduced by the vent holes can prevent the nozzle from "sucking up" or becoming clogged, and can also form a surrounding air curtain to suppress dust rising and improve the working environment; the replaceable cleaning strip design allows users to replace consumables individually according to wear, without having to replace the entire nozzle, reducing operating costs; 3D printing manufacturing supports rapid iteration and personalized customization.

[0017] This utility model solves the technical bottleneck in industrial vacuuming operations for flexible packaging materials such as ton bags through structural innovation and functional integration, and provides an efficient, reliable and intelligent cleaning tool with significant practical value and promising prospects for promotion.

Figure 3 This is a side view of the nozzle body, showing the location of the cleaning strip; The flat nozzle of this industrial vacuum cleaner mainly includes a nozzle body 1, a connecting part 2, a cleaning strip 3, a suction port 11, a vent hole 12, a cylindrical interface section 21, and a conical transition section 22. Detailed Implementation

[0019] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the embodiments described herein are only for explaining this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0020] like Figures 1 to 3 As shown, the industrial vacuum cleaner nozzle of this utility model includes a nozzle body 1 and a connecting part 2 connected to the vacuum cleaner's suction pipe. One end of the connecting part 2 is a cylindrical interface section 21, and the other end is a conical transition section 22. The nozzle body 1 is generally flat and triangular in shape, with a wide suction port at the front end and a tapered transition section 22 at the rear end connected to the conical transition section 22 of the connecting part 2 by a gradually narrowing slope, forming a streamlined structure that is conducive to airflow convergence and pressure distribution optimization.

[0021] The nozzle body 1 is integrally molded from engineering plastic using 3D printing technology, and has a flat triangular shape. The suction port 2 has a lateral width of 100mm and a height of 12mm, forming a wide and thin rectangular opening, which is convenient for covering the typical woven unit of a ton bag. From the suction port backward, the body gradually narrows at a 15° angle, and the diameter of the tapered transition section 22 is reduced to Φ35mm. This tapering structure helps to accelerate airflow and reduce backflow. The cylindrical interface section 21 is equipped with a quick-connect buckle structure to match standard industrial vacuum cleaner hoses.

[0022] On one flat surface of the suction nozzle body 1, vent holes 12 are symmetrically arranged. The vent holes 12 penetrate the side wall, have a diameter of 2 mm, a spacing of 10 mm, are linearly arranged, and are located approximately 15 mm from the edge of the suction port. During dust collection, the vent holes 12 introduce a small amount of ambient air to create a compensating airflow, preventing the suction nozzle from sticking tightly to the surface of the ton bag due to excessive negative pressure. At the same time, they can also form a slight positive pressure barrier around the suction nozzle to suppress dust overflow.

[0023] A cleaning strip 3 is installed at the front end of the suction port 2. The cleaning strip 4 is made of polyurethane material and is glued to the front end of the suction port, and can be removed and replaced at any time.

[0024] In use, connect the nozzle of this industrial vacuum cleaner to the exhaust pipe of the industrial vacuum cleaner. After turning on the equipment, hold the nozzle and make the suction port fit against the surface of the ton bag, and move it slowly. The flat suction port concentrates the airflow to remove dust from crevices, the cleaning strip simultaneously scrapes away stubborn stains, and the vent continuously introduces compensating airflow to maintain operational stability.

[0025] The above description is a further detailed explanation of the present utility model in conjunction with specific embodiments. It should not be considered that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, any simple substitutions made without departing from the concept of the present utility model should be considered to fall within the protection scope of the present utility model.
