Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner equipment technology, and in particular to a bendable vacuum cleaner tube. Background Technology

[0002] Vacuum cleaners typically use airflow to remove dust. A vacuum cleaner usually consists of a fan and a hose. Dust is sucked in by the fan through the air inlet at the front of the hose, filtered, and then expelled from the vacuum cleaner. To adapt to different working environments and vacuuming requirements, existing vacuum cleaner hoses often employ telescopic or flexible hose structures. A typical flexible hose consists of a first section, a second section, and a flexible section joined between the first and second sections. The lower ends of the first and second sections are hinged together, and their upper ends are connected by a snap-fit, allowing the hose to switch between a straight and flexible state. However, this structure is relatively complex and difficult to manufacture. Furthermore, the snap-fit ​​connection is prone to automatically opening under pressure during use in a straight state, resulting in poor stability and room for improvement. Utility Model Content

[0003] The present invention aims to overcome the defects in the prior art by providing a bendable vacuum cleaner hose with a simple and reasonable structure and convenient control operation. The hose assembly can be switched between a straight state and a bendable state simply by adjusting the position of the sliding constraint sleeve to meet the needs of different vacuuming locations.

[0004] To achieve the above objectives, this utility model provides a bendable vacuum cleaner hose, which includes a bendable hose assembly, the hose assembly including a first hose segment, a second hose segment, and a bendable segment disposed between the first hose segment and the second hose segment; The tube assembly is characterized in that it further includes a slidable constraint sleeve, which allows the tube assembly to switch between a straight state and a flexible state by sliding the constraint sleeve to or out of the flexible section.

[0005] A further setting is made so that, in the straight state, the length of the constraint sleeve is greater than the length of the bendable section.

[0006] The first pipe segment is further configured such that the rear end of the first pipe segment facing the second pipe segment is provided with a first connector that is detachably connected to the front port of the constraint sleeve to lock the pipe assembly in a straight state.

[0007] The second pipe segment is further configured such that a second connector is provided at the front end of the second pipe segment facing the first pipe segment, which is detachably connected to the front port of the constraint sleeve to lock the pipe assembly in a flexible state.

[0008] The constraint sleeve is further configured such that it is connected to the first connector and the second connector by threads or by rotational snap-fit.

[0009] A further feature is provided: the rear end of the constraint sleeve is provided with a constriction structure.

[0010] Compared with the prior art, the present invention has a simple and reasonable structure and is easy to control and operate. The tube assembly can be locked in a straight or flexible state simply by connecting the sliding constraint sleeve to the first connector or the second connector, so as to meet the needs of different vacuuming places.

[0013] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0014] This utility model discloses a flexible vacuum cleaner hose, such as... Figure 1 and Figure 2 As shown, the tube assembly 100 is switchable between a straight state and a flexible state. The tube assembly 100 includes a first tube segment 10, a second tube segment 20, and a flexible section 30 disposed between the first tube segment 10 and the second tube segment 20. The flexible section 30 is a flexible hose or a corrugated pipe, so that the first tube segment 10 and the second tube segment 20 can be bent through the flexible section 30 to meet the needs of different vacuuming scenarios.

[0015] In this embodiment, as Figure 1 and Figure 2The pipe assembly 100 also includes a constraint sleeve 40 that can slide along the pipe assembly 100. By sliding the constraint sleeve 40 to or out of the bendable section 30, the pipe assembly 100 can switch between a straight state and a bendable state. Specifically: when the constraint sleeve 40 moves to the bendable section 30 to enclose the bendable section 30, the constraint sleeve 40 restricts the bending deformation of the bendable section 30 within it, and the pipe assembly 100 is in a straight state at this time; when the constraint sleeve 40 slides out of the bendable section 30, the restrictive effect of the constraint sleeve 40 is small, and the bendable section 30 can be bent and deformed freely, and the pipe assembly 100 is in a bendable state at this time.

[0016] In this embodiment, as Figure 1 and 2 As shown, the first pipe segment 10 is provided with a first connector 11 that is detachably connected to the front port of the constraint sleeve 40 at the rear end facing the second pipe segment 20. When the constraint sleeve 40 is slid to the front port of the bendable segment 30 and connected to the first connector 11, the pipe assembly 100 is reliably in a straight state. Preferably, the length of the constraint sleeve 40 is greater than the length of the bendable segment 30. Thus, the rear end of the constraint sleeve 40 extends to the second pipe segment 20 to completely cover the bendable segment 30, which can effectively limit the bending deformation of the bendable segment 30 and ensure that the pipe assembly 100 is stably in a straight state.

[0017] In this embodiment, as Figure 2 As shown, the second pipe section 20 is provided with a second connector 21 that is detachably connected to the front port of the constraint sleeve at the front end of the first pipe section 10. Thus, the constraint sleeve 40 is slid out of the bendable section 30 and connected to the second connector 21. At this time, the pipe assembly 100 is reliably in a bendable state, and the bendable section 30 can be bent freely. Preferably, the rear end of the constraint sleeve 40 is provided with a constriction structure 41 with a diameter smaller than that of the second connector 21, so as to restrict the movement of the constraint sleeve 40.

[0018] In the above scheme, the constraint sleeve 40 is connected to the first connector 11 and the second connector 21 by thread or rotational snap-fit, which facilitates the engagement or separation of the constraint sleeve 40 from the first and second connectors 21.

[0019] Compared with the prior art, the present invention has a simple and reasonable structure and is easy to control and operate. The tube assembly can be locked in a straight or flexible state simply by connecting the sliding constraint sleeve to the first connector or the second connector, so as to meet the needs of different vacuuming places.

[0020] The above-disclosed embodiments are merely examples of the present utility model. However, the present utility model is not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
