Description

Technical Field

[0001] This utility model relates to the field of household appliances, and in particular to a household upright vacuum cleaner. Background Technology

[0002] The technological development of household upright vacuum cleaners stems from the upgrading of household cleaning needs. Early vacuum cleaners were mainly canister-type, which were cumbersome to operate. The upright design improved convenience by integrating the nozzle and the body. With the development of technology, the use of lightweight materials has balanced the strength of the body and portability, while folding and storage technology has optimized the adaptation to small apartment spaces, gradually forming a technological system suitable for modern families.

[0003] The main components of a household upright vacuum cleaner include: motor, cleaning components, filter, and control mechanism. The motor and battery are integrated into the lower part of the body. A rigid rod connects the handle and the suction head. The suction head contains a roller brush and suction inlet, while the dustbin and filter are combined in the airflow channel. During operation, the high-speed rotation of the motor generates negative pressure, drawing dust into the suction head. The rotating roller brush beats the floor, loosening deep-seated dust, which is then carried by the airflow through the rigid rod into the dustbin. Large particles are intercepted by the primary filter, while fine dust is filtered through the secondary filter, and clean air is discharged. The suction power can be adjusted using buttons on the handle, and some models automatically adapt to different cleaning scenarios using sensors for efficient cleaning.

[0004] In existing technologies, some household upright vacuum cleaners are tall, requiring a large vertical space when stored upright, which can make small apartments feel cramped. The rigid sticks are mostly of fixed length, making them difficult to fold or extend. After cleaning, the long rigid sticks make the whole machine take up a lot of horizontal space, making it difficult to fit into narrow corners. Therefore, a household upright vacuum cleaner is proposed to solve the above problems. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Reference Figure 1 and Figure 3The present invention provides an embodiment of a household upright vacuum cleaner, including a suction plate 1 and a dust collection box 33. The opening structure of the suction plate 1 achieves the effect of initial dust collection. Two fixing blocks 2 are fixedly connected to the outer wall of the suction plate 1. The fixed connection between the fixing blocks 2 and the suction plate 1 fixes the support shaft 3. The inner wall of the fixing blocks 2 is fixedly connected to the support shaft 3. The support shaft 3 is used to connect the fixing blocks 2 with the air pump 4 and the support rod 10. The load-bearing capacity of the support shaft 3 achieves the effect of stabilizing the machine body.

[0039] An air pump 4 is fixedly connected to the outer wall of the support shaft 3. The air pump 4 is used to generate negative pressure when it operates, which drives the airflow from the suction plate 1 to the dust box 33, and then the negative pressure suction sucks in the dust. A support rod 10 is fixedly connected to the outer wall of the support shaft 3. The support rod 10 is used to drive the support rod 2 11 and the support rod 3 19 to form a telescopic structure, so that the frame of the support rod 10 can support the whole machine. A through hole 8 is opened on the inner wall of the support rod 10. The through hole 8 provides a sliding channel for the support rod 2 11. A fixing ring 9 is fixedly connected to the outer wall of the support rod 10. The fixing ring 9 is used to prevent slipping and make it easy to operate.

[0040] Reference Figures 3 to 5 Support rod 10 is slidably connected to support rod 2 11 on its inner wall. Support rod 2 11 is used to drive support rod 3 19 to extend and retract synchronously. The sliding adjustment of support rod 2 11 can achieve the effect of adapting to cleaning scenarios of different heights. Support rod 2 11 has a through hole 2 18 on its inner wall. Through hole 2 18 is used to provide sliding space for support rod 3 19. Support rod 2 11 is rotatably connected to a rotating column 13 on its inner wall. Rotating column 13 is used to drive gear 12 to rotate synchronously. Gear 12 is fixedly connected to the outer wall of rotating column 13. Through the meshing of gear 12 with rack plate 20, support rod 3 19 is driven to slide up and down to achieve the effect of smooth height adjustment.

[0041] Support rod 19 is slidably connected to the inner wall of support rod 2 11. Support rod 19 slides in through hole 2 18, which drives the height of the whole machine to be further adjusted. Through hole 22 is opened on the inner wall of support rod 19. Through hole 22 provides a channel for airflow and cables, which facilitates the smooth transmission of dust and signals. A rack plate 20 is fixedly connected to the bottom of support rod 19. The rack plate 20 is used to drive support rod 19 to move with the rotation of gear 12. Then, the stability of rack transmission achieves the effect of precise position adjustment. Multiple slots 21 are opened on the outer wall of support rod 19. The slots 21 are used to fix support rod 19 in a specific position. Then, the positioning of the slots 21 maintains the effect of height adjustment. The inside of the ash box 33 is equipped with a disassembly assembly for replacing filter 31.

[0042] Reference Figure 1 , Figure 6 and Figure 7The disassembly assembly includes a support block 5, which provides a basis for the installation of the handle 6. The bottom of the support block 5 is fixedly connected to the top of the support rod 19. The extension and retraction of the support rod 19 causes the support block 5 to move up and down, so that the fixed connection between the two can adjust the height of the support block 5. The handle 6 is fixedly connected to the outer wall of the support block 5, which is used to facilitate the operation of the vacuum cleaner. The hose 7 is fixedly connected to the outer wall of the support block 5. The hose 7 is used to transport airflow and dust from the support block 5 to the dust collection box 33. Then, the flexibility of the hose 7 achieves the effect of adapting to the extension and retraction of the machine body. The other end of the hose 7 is fixedly connected to the inner wall of the dust collection box 33. The sealing connection of the dust collection box 33 is used to prevent dust leakage.

[0043] A drive motor 23 is fixedly connected to the top of the ash box 33. The drive motor 23 provides power for the rotation of the fan blades 25. A transmission column 24 is fixedly connected to the drive end of the drive motor 23. Through the connection between the transmission column 24 and the drive motor 23, the fan blades 25 are driven to rotate. Multiple fan blades 25 are fixedly connected to the outer wall of the transmission column 24. The fan blades 25 generate airflow as they rotate with the transmission column 24, which creates a negative pressure inside the ash box 33, thus achieving the effect of sucking up dust. A connecting block 26 is fixedly connected to the bottom of the transmission column 24. The connecting block 26 is used to drive the fixed block 37 and the connecting column 28 to move, so that the connecting function of the connecting block 26 achieves the effect of transmitting motion.

[0044] Multiple fixing blocks 27 are fixedly connected to the outer wall of the connecting block 26. The fixing blocks 27 are used to ensure the movement trajectory of the connecting column 28. The connecting column 28 is rotatably connected to the adjacent side of two fixing blocks 27. The transmission action of the connecting column 28 controls the opening and closing of the buckle 29. The other end of the connecting column 28 is rotatably connected to the fixing block 30. The connection between the fixing block 30 and the connecting column 28 drives the buckle 29 to move synchronously. Then, the motion is transmitted to the buckle 29 through the connection action of the fixing block 30. The buckle 29 is fixedly connected to the outer wall of the fixing block 30. The buckle 29 is used to fix or remove the filter screen 31. The filter screen 31 is fixedly connected to the bottom of the buckle 29.

[0045] Reference Figure 6 , Figure 8 and Figure 10 The inner wall of the ash box 33 is fixedly connected to a dust bin 32, which is used to collect and temporarily store dust. The bottom of the ash box 33 is rotatably connected to multiple rollers 38, which are used to drive the ash box 33 to move flexibly. The top of the ash box 33 is detachably connected to an end cap 40, which is used to seal the internal components and prevent dust from leaking out. The outer wall of the ash box 33 is fixedly connected to multiple fixing blocks 34. By fixing the fixing blocks 34 to the ash box 33, the movable block 35 is driven to rotate stably. Then, the support of the fixing blocks 34 ensures the rotation trajectory of the movable block 35.

[0046] Two fixed blocks 34 are rotatably connected to a movable block 35 on their adjacent sides. The movable block 35 rotates around the fixed blocks 34, causing the position of the slot 36 to change, thereby achieving the effect of opening or closing the end cover 40. Two fixed blocks 14 are fixedly connected to the outer wall of the support rod 11. The fixed blocks 14 are used to drive the rotating block 15 to rotate stably. The two fixed blocks 14 are rotatably connected to a rotating block 15 on their adjacent sides. The rotating block 15 is used to drive the protrusion 16 to engage or disengage from the slot 21, thereby achieving the effect of locking or unlocking the position of the support rod 19.

[0047] Reference Figures 8 to 10 The outer wall of the end cap 40 is fixedly connected to a boss 37. The protruding structure of the boss 37 is used to improve the ease of disassembly of the end cap 40. The inner wall of the movable block 35 is provided with a slot 36. The slot 36 is used to make the operation of the movable block 35 more convenient. The outer wall of the rotating block 15 is fixedly connected to a tooth 16. The engagement of the tooth 16 and the slot 21 restricts the sliding of the support rod 19. The inner wall of the rotating block 15 is fixedly connected to a damping shaft 17. The damping shaft 17 is used to prevent the rotating block 15 from rotating arbitrarily. The inner wall of the fixed block 14 is rotatably connected to the outer wall of the damping shaft 17. The outer side of the gear 12 is meshed with the outer side of the rack plate 20. The rotation of the gear 12 drives the rack plate 20 to move up and down, so that the meshing transmission between the gear 12 and the rack plate 20 achieves the effect of precisely adjusting the height of the support rod 19. The two ends of the support shaft 3 are rotatably connected to rollers 39.

[0048] Working principle: When the vacuum cleaner hose needs to be stored, the through hole 8 on the inner wall of support rod 10 provides a convenient channel for storage. Pushing support rod 21 allows it to slide smoothly into the interior of support rod 10 through through hole 8. At this time, the protruding tooth 16, which was originally stuck in the slot 21 of support rod 39, gradually loosens as the rotating block 15 is gently lifted, releasing the fixation on support rod 39. The through hole 28 inside support rod 21 plays a guiding role, and the gear 12 inside it precisely meshes with the rack plate 20 at the bottom of support rod 39. As gear 12 slowly rotates, rack plate 20 drives support rod 39 to slide smoothly downward. Finally, the three support rods are retracted inside support rod 10, saving a lot of storage space.

[0049] When the vacuum cleaner filter 31 needs cleaning or replacement, first locate the movable block 35 with the slot 36, gently turn it, and the movable block 35 will open, along with the end cover 40. Since the end cover 40 is connected to the drive motor 23, when the end cover 40 is opened, the transmission column 24 at the drive end of the drive motor 23 will be lifted. The connecting block 26 at the bottom of the transmission column 24 moves accordingly, pulling and rotating the connecting column 28 connected to the adjacent side of the two fixed blocks 27. The connecting column 28 then causes the latches 29 to loosen. After all the latches 29 are released, the filter 31 can be easily removed for cleaning or replacement.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
