[0002] In modern life, vacuum cleaners have become an essential tool for cleaning homes and offices. However, traditional vacuum cleaners have some shortcomings in terms of use and storage.

[0003] Traditional vacuum cleaners are typically of a fixed length, making them difficult to adapt to different spaces and cleaning scenarios. When cleaning tasks at higher or lower positions, their length limitation may prevent effective cleaning, reducing their flexibility. Furthermore, traditional vacuum cleaners are relatively large, taking up considerable space when stored, which is inconvenient for users.

[0004] Furthermore, the suction head angle of traditional vacuum cleaners is usually fixed, making it difficult to adjust to different cleaning surfaces and corners, thus limiting cleaning effectiveness. In some complex cleaning environments, such as under furniture or in narrow corners, traditional vacuum cleaners struggle to perform at their best.

[0005] To address these issues, this patent proposes a foldable vacuum cleaner. Through a unique structural design, this vacuum cleaner achieves adjustable length, foldability, and a rotatable nozzle angle, significantly improving its applicability and convenience. Utility Model Content

[0012] In one embodiment, locking rings are slidably connected between the two upper limiting rings and the two lower limiting rings, and locking springs are provided at the ends of the two locking rings near the junction of the lower folding tube and the upper folding tube.

[0013] In one embodiment, the locking ring is elastically connected between the limiting rings on both sides by a locking spring, and multiple telescopic holes are provided inside the lower side of the outer wall of the lower folding tube cylinder and the upper side of the outer wall of the upper folding tube cylinder.

[0014] In one embodiment, the plurality of telescopic holes are located inside the two locking rings, and a locking slider is engaged inside the end of the plurality of telescopic holes away from the locking rings, and the plurality of locking sliders are slidably connected inside the plurality of telescopic holes.

[0015] In one embodiment, the locking slider is attached to the outer cylindrical wall of the lower or upper telescopic tube at the end away from the locking ring, and a compression sliding hole is provided at the end of the locking slider near the locking ring. A compression head is inserted into the end of the compression sliding hole near the locking ring, and the compression head is slidably connected inside the compression sliding hole.

[0016] In one embodiment, the extrusion head is hemispherical at the end near the locking ring and is attached to the inner wall of the locking ring through a telescopic hole.

[0034] This utility model provides, for example Figures 1-5 The foldable vacuum cleaner shown includes a suction head 1, with a connecting base 2 connected to the rear end of the suction head 1 and rotatably connected via the connecting base 2. A lower telescopic tube 3 is connected to the upper end of the connecting base 2, and a lower folding tube 4 is sleeved on the outer side of the upper end of the lower telescopic tube 3. An upper folding tube 5 is connected to the upper end of the lower folding tube 4, and an upper telescopic tube 6 is inserted into the inner side of the upper end of the upper folding tube 5. A control mechanism 7 is connected to the upper end of the upper telescopic tube 6, and a control button is provided inside the front end of the control mechanism 7. A suction unit 8 is connected to the upper end of the control mechanism 7. The upper end is connected to a handle 9. The vacuum cleaner controls the switch and gear of the suction machine 8 through the control mechanism 7, and generates suction through the suction machine 8. The suction machine 8 is connected to the suction pipe composed of the lower telescopic tube 3, the lower folding tube 4, the upper folding tube 5 and the upper telescopic tube 6 through the control mechanism 7, and is connected to the connecting seat 2 through the suction pipe, and then connected to the inside of the suction head 1 through the connecting seat 2. At the same time, the suction head 1 is rotatably connected through the connecting seat 2, so that the lower opening of the suction head 1 can generate suction, and the floor is cleaned by suction.

[0035] Preferably, multiple movable rollers 10 are provided inside the lower left and right sides of the suction head 1, and the lower ends of the multiple movable rollers 10 protrude outside the lower end of the suction head 1. Since the lower telescopic tube 3 can extend and retract inside the lower end of the lower folding tube 4, and the upper telescopic tube 6 can extend and retract inside the upper end of the upper folding tube 5, the vacuum cleaner can adjust its overall length by extending and retracting the lower telescopic tube 3 and the upper telescopic tube 6, and can adjust the suction angle by rotating the suction head 1 at the lower end of the connecting seat 2. At the same time, it can move flexibly on the ground by the multiple movable rollers 10, so that the vacuum cleaner can be better used in different usage environments and improve its usage flexibility.

[0036] Preferably, a folding hinge 11 is fixedly connected to the rear end of the lower folding tube 4 and the upper folding tube 5. The lower folding tube 4 and the upper folding tube 5 are rotatably connected through the folding hinge 11. A fixed rotating seat 12 is fixedly connected to the lower front end of the upper folding tube 5. A fixed stud 13 is rotatably connected to the front end of the fixed rotating seat 12. A fixed buckle 14 is fixedly connected to the upper front end of the lower folding tube 4. The fixed stud 13 is snapped into the fixed buckle 14 and fixedly connected by bolts. Since the lower folding tube 4 and the upper folding tube 5 can rotate through the folding hinge 11, they can be connected and folded through rotation. When connected, they can be fixed by the fixed rotating seat 12, the fixed stud 13 and the fixed buckle 14, making the vacuum cleaner more stable when in use and foldable when not in use, saving storage space.

[0037] Preferably, a limiting groove 15 is provided at the upper end of the lower folding tube 4, and a sealing ring 16 is snapped into the limiting groove 15. A sealing groove 17 is provided at the upper end of the sealing ring 16. A sealing head 18 is fixedly connected to the lower end of the upper folding tube 5, and the sealing head 18 is snapped into the sealing groove 17. During the communication between the lower folding tube 4 and the upper folding tube 5, the sealing head 18 can be snapped into the sealing groove 17 by rotation, so that the lower folding tube 4 and the upper folding tube 5 can be sealed through the sealing ring 16 and the sealing head 18, ensuring that the suction power of the vacuum cleaner remains stable.

[0038] Preferably, two limiting rings 19 are fixedly connected to the lower end of the lower folding tube 4 and the upper end of the upper folding tube 5. Locking rings 20 are slidably connected between the two upper limiting rings 19 and the two lower limiting rings 19. A locking spring 21 is provided at one end of each locking ring 20 near the junction of the lower folding tube 4 and the upper folding tube 5. The locking rings 20 are elastically connected between the limiting rings 19 on both sides through the locking springs 21. Multiple telescopic holes 22 are provided inside the lower cylindrical outer wall of the lower folding tube 4 and the upper cylindrical outer wall of the upper folding tube 5. The multiple telescopic holes 22 respectively... Located inside the two locking rings 20, multiple telescopic holes 22 have locking sliders 23 engaged at the ends away from the locking rings 20. These sliders 23 are slidably connected inside the telescopic holes 22. The ends of the sliders 23 away from the locking rings 20 are attached to the cylindrical outer wall of the lower telescopic tube 3 or the upper telescopic tube 6. A compression hole 24 is engaged at the end of the slider 23 closest to the locking rings 20. A compression head 25 is engaged inside the end of the compression hole 24 closest to the locking rings 20, and the compression head 25 is slidably connected inside the compression hole 24. The compression head 25 is close to the locking rings 20. One end of the retaining ring 20 is hemispherical and fits against the inner wall of the locking retaining ring 20 through the telescopic hole 22. The end of the squeezing head 25 away from the locking retaining ring 20 fits against the inner wall of the squeezing slide hole 24 away from the locking retaining ring 20. A pop-out spring 26 is provided inside the end of the squeezing head 25 away from the locking retaining ring 20, and is elastically connected to the inside of the squeezing slide hole 24 through the pop-out spring 26. During the adjustment of the overall length of the vacuum cleaner, the locking retaining ring 20 is slid towards the side near the junction of the lower folding tube 4 and the upper folding tube 5, thus sliding the locking retaining ring 20 from the outside of the multiple squeezing heads 25. The multiple extrusion heads 25 are unobstructed externally. Under the action of the pop-out spring 26, the multiple extrusion heads 25 separate from the inner wall of the end of the extrusion sliding hole 24 away from the locking ring 20, and pop out from the opening of the telescopic hole 22 near the locking ring 20. At this time, the multiple locking sliders 23 can extend and retract inside the telescopic hole 22, releasing the lock between the multiple locking sliders 23 and the outer wall of the cylinder of the lower telescopic tube 3 and the upper telescopic tube 6, so that the lower telescopic tube 3 and the upper telescopic tube 6 can extend and retract smoothly inside the lower folding tube 4 and the upper folding tube 5, allowing the vacuum cleaner to be adjusted smoothly in terms of overall length.

[0039] Preferably, after the overall length of the vacuum cleaner is adjusted, the locking ring 20 is released. Under the action of the locking spring 21, the locking ring 20 slides again to the outside of the multiple extrusion heads 25. Since the outer wall of the locking ring 20 at the end away from the junction of the lower folding tube 4 and the upper folding tube 5 is arc-shaped, and the extrusion head 25 is hemispherical at the end near the locking ring 20, the multiple extrusion heads 25 can be extruded into the telescopic hole 22 again through the hemispherical outer wall and the arc surface of the locking ring 20. At the same time, the multiple locking sliders 23 are extruded, so that the multiple locking sliders 23 are tightly attached to the outer wall of the lower telescopic tube 3 and the upper telescopic tube 6, thereby locking the position of the lower telescopic tube 3 and the upper telescopic tube 6, and thus locking the overall length of the vacuum cleaner, ensuring the structural stability of the vacuum cleaner.

[0040] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
