Description

Technical Field

[0001] This application relates to the field of vacuum cleaner hose technology, and more specifically, to an anti-whistling extrusion tube. Background Technology

[0002] Corrugated hoses are an important component of vacuum cleaners. Current vacuum cleaner products have the following main requirements for corrugated hoses: 1. Good elasticity, achieving a certain stretch ratio; 2. A certain degree of flexibility, while maintaining internal space during bending, preventing the hose from collapsing or deforming. To meet these requirements, the hose manufacturing industry has made numerous improvements to the hose structure.

[0003] Among them, corrugated extrusion hoses have a huge market prospect. The extensibility of corrugated extrusion hoses is the key to their competitive advantage in the market. In order to increase the extensibility of extrusion hoses, the extensibility units that make up the extrusion hoses are usually designed to be pleated. When multiple pleated extensibility units are combined to form an extrusion hose, stretching the extrusion hose stretches the pleats of the extensibility units, and compressing the extrusion hose compresses the pleats of the extensibility units. In this way, the extrusion hose's extensibility is guaranteed. However, the inner wall of the extrusion hose will form a lot of grooves due to the extensibility units. When the extrusion hose needs airflow, such as when a vacuum cleaner sucks in air, the airflow will enter the grooves and produce a whistling sound. Utility Model Content

The anti-whistling structure is configured as a protruding structure, extending from the inner wall of the tube body away from the anti-whistling structure extrusion tube towards the tube body axis. The anti-whistling structure is closer to the tube body axis than the first tube segment.

[0025] It should also be noted that, for ease of description, only the parts relevant to this application are shown in the accompanying drawings. Unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other.

[0026] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0027] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 3 As shown, the anti-whistling structure extrusion tube 100 of this application includes a first tube section 10, a second tube section 20, a third tube section 30, a connecting part 40, and an anti-whistling structure 50; the first tube section 10 is arranged in an inverted "U" shape, one end of the second tube section 20 is connected to one end of the first tube section 10, and the second tube section 20 is a horizontal section; the third tube section 30 is connected to the other end of the second tube section 20.

[0029] Specifically, the first pipe section 10 includes a first section body 101, a second section body 102, a third section body 103, and a connecting groove 104. The second section body 102 is arranged in an arc shape. One end of the second section body 102 is connected to the first section body 101, and the other end is connected to the third section body 103. The first section body 101, the second section body 102, and the third section body 103 together form a "U" shape. The connecting groove 104 is formed within the first section body 101, the second section body 102, and the third section body 103.

[0030] When the anti-whistling extruded tube 100 of this application is formed, the tube segment unit composed of the first tube segment 10, the second tube segment 20, the third tube segment 30 and the anti-whistling structure 50 is interconnected with the adjacent tube segment unit composed of the first tube segment 10, the second tube segment 20, the third tube segment 30 and the anti-whistling structure 50 to form the tube wall of the anti-whistling extruded tube 100; specifically, the first segment body 101 on the first tube segment 10 in the later tube segment unit crosses the third tube segment 30 in the previous tube segment unit (at this time, the third tube segment 30 in the previous tube segment unit is placed in the connecting groove 104 in the later tube segment unit), and the first segment body 101 in the later tube segment unit and the third tube segment 30 in the previous tube segment unit are connected by the connecting part 40; in this embodiment, the connecting part 40 is an adhesive layer, specifically glue; in other embodiments, it can also be other adhesive materials, or it can be formed by melting the surface of the tube segment unit, bonding them together and then solidifying.

[0031] In some embodiments, the side of the anti-whistling structure 50 away from the outer wall of the anti-whistling structure extrusion tube 100 is closer to the axis of the anti-whistling structure extrusion tube 100 than the side of the first tube segment 10 away from the outer wall of the anti-whistling structure extrusion tube 100. That is, the anti-whistling structure 50 is closer to the axis of the anti-whistling structure extrusion tube 100 than the first tube segment 10, making it less likely for airflow to enter the connecting groove 104. Alternatively, the anti-whistling structure 50 is configured as a protruding structure, extending from the inner wall of the tube away from the anti-whistling structure extrusion tube 100 towards the axis of the tube body; the anti-whistling structure 50 is closer to the axis of the tube body than the first tube segment 10.

[0032] In some embodiments, the anti-whistling structure 50 is a protrusion provided at the connection between the first pipe section 10 and the second pipe section 20, which is formed by extending outward from at least a portion of the surface to reduce the airflow entering the connection groove 104 and reduce whistling.

[0033] Preferably, an arc-shaped portion 301 is provided at the connection between the second pipe section 20 and the third pipe section 30, which makes the transition smoother and reduces whistling.

[0034] In some embodiments, the anti-whistling structure 50 is a protrusion provided at the connection between the second pipe section 20 and the third pipe section 30, which is formed by extending outward from at least a portion of the surface to reduce the airflow entering the connection groove 104 and reduce whistling.

[0035] Preferably, an arc-shaped portion 301 is provided at the connection between the first pipe section 10 and the second pipe section 20, so that the transition is smoother and the whistling is reduced.

[0036] In some embodiments, the anti-whistling structure 50 is a protrusion respectively provided at the connection between the first pipe section 10 and the second pipe section 20 and the connection between the second pipe section 20 and the third pipe section 30, which is formed by extending outward from at least a portion of the surface to reduce the airflow entering the connection groove 104 and reduce whistling.
