Description

Technical Field

[0001] This application relates to the field of vacuum cleaner hose technology, and in particular to a retractable and bendable vacuum cleaner hose. Background Technology

[0002] Household vacuum cleaners utilize a fan impeller driven at high speed by an electric motor. The blades in the impeller continuously perform work on the air, energizing it and expelling it from the fan at extremely high speed. Simultaneously, the air in the suction section at the front of the fan continuously replenishes the air in the impeller, creating a momentary vacuum within the suction section. This creates a significant negative pressure difference between the suction section and the external atmospheric pressure. Under this negative pressure difference, debris and dust near the nozzle are drawn into the vacuum cleaner by the airflow. Inside the vacuum cleaner, the debris and dust pass through a filter, remaining in the dust collection box, while the filtered air is expelled from the vacuum cleaner into the room, thus completing the entire vacuuming process.

[0003] However, the suction tubes of existing vacuum cleaners are usually made of rigid metal tubes. When cleaning low places such as under beds, tables, or cabinets, people usually have to bend over, squat, or lie down to insert the suction head into the bottom of the bench or cabinet, which makes the cleaning work extremely tiring and reduces the convenience of using the vacuum cleaner, which is obviously a drawback. Utility Model Content

[0004] To improve the convenience of using a vacuum cleaner, this application provides a retractable and bendable vacuum cleaner hose.

[0005] The retractable and bendable vacuum cleaner hose provided in this application adopts the following technical solution:

[0006] A retractable and bendable vacuum cleaner hose includes a first pipe and a second pipe, which are rotatably connected by a hinge assembly. The hinge assembly includes a first connecting sleeve connected to the end of the first pipe and a second connecting sleeve connected to the second pipe. The first connecting sleeve and the second connecting sleeve are hinged together. A flexible hose is provided between the first pipe and the second pipe, with one end of the flexible hose on the first pipe and the other end on the second pipe.

[0007] By adopting the above technical solution, the first pipe and the second pipe are connected to each other through a hinge assembly. At this time, the first pipe can be folded relative to the second pipe, and the first pipe and the second pipe are connected through a flexible hose to ensure the continuity of the dust suction channel. When the user uses the vacuum cleaner to clean a relatively low position, the user only needs to bend the first pipe and the second pipe relative to each other, and the first pipe or the second pipe can be inserted into the dust removal position. At this time, the user does not need to bend over, squat or lie down, allowing the user to easily complete the dust removal work and improving the convenience of the user in using the vacuum cleaner.

[0008] Optionally, the first connecting sleeve and the second connecting sleeve are provided with locking components, which are used to keep the axes of the first pipe and the second pipe in a straight line connection state.

[0009] By adopting the above technical solution, when the vacuum cleaner does not need to be folded, the user can keep the first and second pipes in a straight connection state by using the locking component. This avoids the loss of suction power caused by the bending of the hose when the vacuum cleaner does not need to be folded, thus improving the vacuuming efficiency. At the same time, it also avoids hose wear caused by uneven force at the bending part, thus extending the service life of the hose.

[0010] Optionally, the locking assembly includes a locking sleeve that is slidably fitted onto the outer surfaces of the first connecting sleeve and the second connecting sleeve. The locking sleeve is provided with a guide block. Both the first connecting sleeve and the second connecting sleeve are provided with guide grooves that slide with the guide block. The second connecting sleeve is provided with an arc groove that communicates with the guide groove. The inner sidewall of the arc groove is provided with an insertion groove that inserts into the guide block. When the guide block is inserted into the insertion groove, the locking sleeve is fitted onto the hinge portion of the first connecting sleeve and the second connecting sleeve.

[0011] By adopting the above technical solution, when the vacuum cleaner does not need to be folded, the user slides the locking sleeve to the connection between the arc groove and the guide groove through the guide groove and the guide block. Then, the user rotates the locking sleeve to slide the guide block to the connection between the arc groove and the insertion groove. Finally, the user slides the locking sleeve down to insert the guide block into the insertion groove. At this time, with the insertion groove and the guide block in cooperation, the locking sleeve stays at the connection between the first connecting sleeve and the second connecting sleeve. Under the limitation of the locking sleeve, the relative rotation between the first connecting sleeve and the second connecting sleeve is restricted, thereby keeping the first pipe and the second pipe in a straight line connection state.

[0012] Optionally, a fixing groove is formed on the inner sidewall of the arc groove away from the insertion groove. A clamping block is slidably connected in the fixing groove. The clamping block has an inclined surface that slides with the guide block. A clamping spring is provided in the fixing groove. One end of the clamping spring is provided on the inner sidewall of the fixing groove, and the other end is provided on the clamping block. When the clamping spring pushes the clamping block to abut against the guide block, the guide block is inserted into the insertion groove.

[0013] By adopting the above technical solution, when the guide block moves towards the insertion slot inside the arc groove, the guide block pushes the clamping block into the fixed slot through the inclined surface. At this time, the clamping spring is in a compressed state. When the guide block moves to the connection between the arc groove and the insertion slot, the pressure on the clamping spring disappears, and the clamping spring releases energy to push the clamping block towards the arc groove. The clamping block abuts against the guide block and pushes the guide block into the insertion slot, thereby improving the stability of the guide block inserted into the insertion slot and thus improving the locking effect of the locking assembly.

[0014] Optionally, both ends of the hose are fitted with connecting rings, and the ends of the first pipe and the second pipe near the hose are provided with connecting grooves. The connecting rings are fixedly connected to the connecting grooves by multiple connecting bolts.

[0015] By adopting the above technical solution, the connection ring and connection bolt enable detachable connection between the hose, the first pipe, and the second pipe, making it convenient for users to replace damaged hoses in a timely manner, thereby ensuring the smooth use of the vacuum cleaner.

[0016] Optionally, the first pipe is threaded to the end of the first connecting sleeve, and the second pipe is threaded to the end of the second connecting sleeve.

[0017] By adopting the above technical solution, the threaded connection enables a detachable connection between the first pipe, the second pipe, and the hinge assembly, making it convenient for users to disassemble and replace damaged parts. At the same time, when the first pipe, the second pipe, and the rotating assembly are separated, the overall length of the vacuum hose is effectively reduced, making it easier to package and transport.

[0018] Optionally, the second pipe includes an outer pipe and an inner pipe, the inner pipe is slidably sleeved inside the outer pipe, a plurality of pin holes are evenly spaced on the outer surface of the inner pipe, a fixing component is provided on the outer pipe, and the outer pipe is connected to the inner pipe through the fixing component.

[0019] By adopting the above technical solution, when it is necessary to adjust the length of the second pipe, the user can cancel the fixing effect of the fixing component and then pull the outer pipe outward. At this time, the length of the second pipe is extended, thereby realizing the adjustment of the overall vacuum pipe length. Compared with directly replacing vacuum pipes of different lengths, the process of adjusting the length of the vacuum pipe is more convenient, thereby further improving the convenience of the user in using the vacuum cleaner.

[0020] Optionally, the fixing component includes an intermediate sleeve disposed on the outer surface of the outer tube, an adjusting screw is threadedly connected inside the intermediate sleeve, the end of the adjusting screw is provided with a pin rod that engages with the pin hole, and the end of the adjusting screw away from the pin rod is provided with an adjusting knob.

[0021] By adopting the above technical solution, when it is necessary to adjust the length of the second pipe, the user rotates the adjustment knob in the opposite direction. The adjustment knob drives the adjustment screw to rotate in the opposite direction, and the adjustment screw drives the pin to disengage from the pin hole. At this time, the fixed connection between the inner and outer pipes disappears, and the user pulls the outer pipe outward, thereby realizing the adjustment of the length of the vacuum pipe. After the adjustment is completed, the user rotates the adjustment knob in the forward direction. The adjustment knob drives the pin to insert into the new pin hole through the adjustment screw, thereby realizing the fixation of the inner and outer pipes after adjustment.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application provides a first pipe, a second pipe, a hose, and a hinge assembly, which allows the first pipe to be folded relative to the second pipe. When a user uses a vacuum cleaner to clean a low-lying area, the user only needs to bend the first pipe and the second pipe relative to each other, and the first pipe or the second pipe can be inserted into the dust removal position. At this time, the user does not need to bend over, squat, or lie down, allowing the user to easily complete the dust removal work and improving the convenience of using the vacuum cleaner.

[0024] 2. By setting a locking component, when the vacuum cleaner does not need to be folded, the user can keep the first pipe and the second pipe in a straight connection state by using the locking component, thereby avoiding the loss of suction power caused by the bending of the hose when the vacuum cleaner does not need to be folded, and improving the vacuuming efficiency; at the same time, it also avoids the wear of the hose caused by uneven force at the bending part, and extends the service life of the hose.

[0025] 3. This application, by setting an outer tube, an inner tube, and a fixing component, allows the user to release the fixing component when the length of the second tube needs to be adjusted. Then, the user pulls the outer tube outward, which extends the length of the second tube, thereby achieving the adjustment of the overall vacuum tube length. Compared with directly replacing vacuum tubes of different lengths, this makes the vacuum tube length adjustment process more convenient, thereby further improving the user's convenience in using the vacuum cleaner.

Detailed Implementation

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a retractable and bendable vacuum cleaner hose.

[0034] Reference Figure 1 A retractable and bendable vacuum cleaner hose includes a first pipe 1 and a second pipe 2. One end of the first pipe 1 and one end of the second pipe 2 are disposed opposite each other. In this embodiment, both the first pipe 1 and the second pipe 2 are made of metal. The first pipe 1 and the second pipe 2 are rotatably connected by a hinge assembly 3. The hinge assembly 3 includes a first connecting sleeve 31 and a second connecting sleeve 32. The first connecting sleeve 31 and the second connecting sleeve 32 are hinged together. The end of the first connecting sleeve 31 away from the hinge is disposed on the first pipe 1, and the end of the second connecting sleeve 32 away from the hinge is disposed on the second pipe 2. A flexible hose 33 is disposed between the first pipe 1 and the second pipe 2. One end of the flexible hose 33 is disposed on the first pipe 1, and the other end is disposed on the second pipe 2. In this embodiment, the flexible hose 33 is a corrugated pipe.

[0035] The first pipe 1 and the second pipe 2 are connected to each other by a hinge assembly 3. At this time, the first pipe 1 can be folded relative to the second pipe 2, and the first pipe 1 and the second pipe 2 are connected by a hose 33 to ensure the continuity of the dust collection channel. When the user uses the vacuum cleaner to clean a relatively low position, the user only needs to bend the first pipe 1 and the second pipe 2 relative to each other, and the first pipe 1 or the second pipe 2 can be inserted into the dust removal position. At this time, the user does not need to bend over, squat or lie down, which makes it easy for the user to complete the dust removal work and improves the convenience of the user in using the vacuum cleaner.

[0036] Reference Figure 1 and Figure 2The first pipe 1 is threadedly engaged with the end of the first connecting sleeve 31 away from the hinge, and the second pipe 2 is threadedly engaged with the end of the second connecting sleeve 32 away from the hinge. This facilitates the disassembly of the first pipe 1, the second pipe 2, and the hinge assembly, making packaging and transportation easier.

[0037] Reference Figure 1 and Figure 2 Both ends of the hose 33 are fixedly fitted with connecting rings 331. The ends of the first pipe 1 and the second pipe 2 near the hose 33 are both provided with connecting grooves 4. The connecting rings 331 are fixedly connected to the connecting grooves 4 by multiple connecting bolts 332. This arrangement enables the hose 33 to be detachably connected to the first pipe 1 and the second pipe 2, making it convenient for users to replace the damaged hose 33 in a timely manner, thereby ensuring the smooth use of the vacuum cleaner.

[0038] Reference Figure 1 , Figure 3 and Figure 4 The first connecting sleeve 31 and the second connecting sleeve 32 are provided with locking components 5. When the vacuum cleaner does not need to be folded, the locking components 5 make the axes of the first pipe 1 and the second pipe 2 in a straight line connection state, thereby avoiding the loss of suction power caused by the bending of the hose 33 when the vacuum cleaner does not need to be folded, and improving the vacuuming efficiency; at the same time, it also avoids the wear of the hose 33 caused by uneven force at the bending part, and extends the service life of the hose 33.

[0039] Reference Figure 1 , Figure 3 and Figure 4 The locking assembly 5 includes a locking sleeve 51 that is slidably fitted on the outer surfaces of the first connecting sleeve 31 and the second connecting sleeve 32. A guide block 52 is fixedly connected to the inner surface of the locking sleeve 51. The first connecting sleeve 31 and the second connecting sleeve 32 are each provided with a guide groove 6 that slides with the guide block 52. The second connecting sleeve 32 is provided with an arc groove 61 that communicates with the guide groove 6. The center of the arc groove 61 is located on the axis of the first connecting sleeve 31 and the second connecting sleeve 32, and the radius of the arc groove 61 is perpendicular to the axis of the first connecting sleeve 31 and the second connecting sleeve 32. An insertion groove 62 is provided on the inner side wall of the arc groove 61 that is inserted into the guide block 52. When the guide block 52 is inserted into the insertion groove 62, the locking sleeve 51 is fitted on the hinge part of the first connecting sleeve 31 and the second connecting sleeve 32.

[0040] Reference Figure 1 , Figure 3 and Figure 4A fixing groove 63 is provided on the inner side wall of the arc groove 61 away from the insertion groove 62. A pressing block 631 is slidably connected in the fixing groove 63. The pressing block 631 has an inclined surface (not shown in the figure) that slides with the guide block 52. A pressing spring 632 is provided in the fixing groove 63. One end of the pressing spring 632 is fixedly connected to the inner side wall of the fixing groove 63, and the other end is fixedly connected to the pressing block 631. When the pressing spring 632 pushes the pressing block 631 to abut against the guide block 52, the guide block 52 is inserted into the insertion groove 62.

[0041] When the vacuum cleaner does not need to be folded, the user slides the locking sleeve 51 to the connection between the arc groove 61 and the guide groove 6 through the guide groove 6 and the guide block 52. The guide block 52 pushes the pressing block 631 into the fixed groove 63 through the inclined surface. At this time, the pressing spring 632 is in a compressed state. When the guide block 52 moves to the connection between the arc groove 61 and the insertion groove 62, the pressure on the pressing spring 632 disappears. The pressing spring 632 releases energy and pushes the pressing block 631 toward the arc groove 61. The pressing block 631 abuts against the guide block 52 and pushes the guide block 52 into the insertion groove 62. At this time, with the insertion groove 62 and the guide block 52 in the insertion cooperation, the locking sleeve 51 stays at the connection between the first connecting sleeve 31 and the second connecting sleeve 32. Under the limitation of the locking sleeve 51, the relative rotation between the first connecting sleeve 31 and the second connecting sleeve 32 is restricted, so that the first pipe 1 and the second pipe 2 are kept in a straight line connection state.

[0042] Reference Figure 2 and Figure 5 The second pipe 2 includes an outer pipe 21 and an inner pipe 22. The inner pipe 22 is slidably sleeved inside the outer pipe 21. The end of the inner pipe 22 is threadedly connected to the second connecting sleeve 32. The outer surface of the inner pipe 22 is provided with a plurality of pin holes 221 evenly spaced along the axial direction. The outer pipe 21 is provided with a fixing component 7. The fixing component 7 includes an intermediate sleeve 71 fixedly connected to the outer surface of the outer pipe 21. An adjusting screw 72 is threadedly connected inside the intermediate sleeve 71. The end of the adjusting screw 72 is coaxially fixedly connected to a pin rod 73 that is inserted into the pin hole 221. In this embodiment, the pin rod 73 and the adjusting screw 72 are integrally formed. The outer surface of the outer pipe 21 is provided with a clearance groove (not shown in the figure) that is slidably engaged with the pin rod 73. The end of the adjusting screw 72 away from the pin rod 73 is coaxially fixedly connected to an adjusting knob 74. The adjusting knob is rotatably disposed on the outer surface of the intermediate sleeve 71.

[0043] When the length of the second pipe 2 needs to be adjusted, the user rotates the adjustment knob 74 in the opposite direction. The adjustment knob 74 drives the adjustment screw 72 to rotate in the opposite direction, and the adjustment screw 72 drives the pin 73 to disengage from the pin hole 221. At this time, the fixed connection between the inner tube 22 and the outer tube 21 is lost. The user pulls the outer tube 21 outward, thereby adjusting the length of the vacuum cleaner pipe. After the adjustment is completed, the user rotates the adjustment knob 74 in the forward direction. The adjustment knob 74 drives the pin 73 to insert into the new pin hole 221 through the adjustment screw 72, thereby fixing the inner tube 22 and the outer tube 21 after adjustment. Compared with directly replacing vacuum cleaner pipes of different lengths, the process of adjusting the length of the vacuum cleaner pipe is more convenient, thereby further improving the convenience of using the vacuum cleaner.

[0044] The implementation principle of a retractable and bendable vacuum cleaner hose according to an embodiment of this application is as follows: the first pipe 1 and the second pipe 2 are connected to each other through a hinge assembly 3. At this time, the first pipe 1 can be folded relative to the second pipe 2, and the first pipe 1 and the second pipe 2 are connected through a flexible hose 33 to ensure the continuity of the vacuuming channel. When the user uses the vacuum cleaner to clean a relatively low position, the user only needs to bend the first pipe 1 and the second pipe 2 relative to each other, and the first pipe 1 or the second pipe 2 can extend to the dust removal position. At this time, the user does not need to bend over, squat or lie down, so that the user can easily complete the dust removal work and improve the convenience of the user using the vacuum cleaner.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
