Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaners, and more specifically, to a stick vacuum cleaner. Background Technology

[0002] Modern household vacuum cleaners have shed their traditional bulky, long-cord image, with most mainstream products featuring efficient and flexible cordless handheld designs. They are generally powered by lithium batteries, providing up to tens of minutes of runtime, freeing cleaning from the constraints of power outlets. In terms of core technology, multi-cone cyclone separation technology has become standard.

[0003] Currently, vacuum cleaner filters are prone to clogging due to the accumulation of hair and dust during use. Cleaning the filters often requires disassembling the device, which is cumbersome and inefficient. If not cleaned in time, the clogging will seriously affect the suction power and cleaning efficiency of the vacuum cleaner. The dust cup cover of traditional vacuum cleaners has a relatively complex structure, including connecting parts and release components, and its overall compactness is not good.

[0004] To address the aforementioned problems, this application proposes a stick vacuum cleaner. Utility Model Content

[0005] The purpose of this invention is to provide a stick vacuum cleaner that prevents filter clogging during use with a scraper and ensures thorough cleaning when emptying the dustbin, while completely isolating the hands from dust. A flexible design with a soft rubber baffle efficiently collects and removes dust, eliminating the need for a traditional dust cover and improving integration. A floor brush adjacent to the dustbin shortens the air duct to reduce suction loss and allows for quick disassembly for easy cleaning and maintenance, thus solving problems in existing technologies.

[0006] The objective of this utility model can be achieved through the following technical solution: A stick vacuum cleaner includes a floor brush and a stick body. The floor brush includes a base, the base is provided with a suction port and an adapter, the adapter is connected to the suction port via a flexible hose, the stick body is rotatably connected to the floor brush via the adapter, the stick body is provided with a vacuum generating device and a dust collection bin communicating with the suction port, the vacuum generating device provides suction force to allow dust-laden airflow to enter the dust collection bin from the suction port, the bottom of the dust collection bin is detachably connected to the adapter and forms an airflow channel, and the dust collection bin forms at least a part of the stick body.

[0007] Preferably, the lower part of the dust collection bin forms an air inlet channel connected to the adapter, the upper part of the dust collection bin forms a dust collection chamber, a baffle that can be flipped up and down is provided between the air inlet channel and the dust collection chamber, a filter screen and a HEPA filter are formed on one side of the dust collection chamber along the axial direction of the rod-type body, a scraper for scraping the filter screen is also provided inside the dust collection chamber, a sliding sleeve for driving the scraper to slide up and down is provided outside the dust collection bin, a first adsorption element is built into the scraper, and a second adsorption element capable of adsorbing the first adsorption element is provided on the sliding sleeve.

[0008] Preferably, the top of the dust collection chamber is equipped with a third adsorbent that can adsorb the first adsorbent.

[0009] Preferably, the first adsorption element is a positive magnet, the second adsorption element is a negative magnet, and the third adsorption element is an iron block.

[0010] Preferably, a T-shaped slot is formed on one side of the dust collection bin. The baffle includes a snap-fit ​​end and a flip-up end. The snap-fit ​​end is snapped and fixed in the T-shaped slot. When there is no external force, the baffle isolates the air inlet channel from the dust collection chamber. Under the suction of the vacuum generator, the flip-up end flips upward relative to the snap-fit ​​end, allowing the dust-laden airflow to enter the dust collection chamber. When subjected to the downward driving force of the sliding sleeve, the flip-up end flips downward relative to the snap-fit ​​end, allowing the dust collected in the dust collection chamber to be discharged through the air inlet channel.

[0011] Preferably, the baffle is made of soft rubber material, and the soft rubber material is silicone.

[0012] Preferably, the outer side of the dust collection bin has two slide rails formed along the axial direction, and the inner side of the sliding sleeve is provided with an insert corresponding to the slide rails.

[0013] Preferably, the vacuum generating device is located above the dust collection bin, and an air outlet is formed on the surface of the rod-shaped body located on one side of the vacuum generating device.

[0014] Preferably, the base is rotatably connected to a first roller brush and a second roller brush, the first roller brush and the second roller brush are respectively located on the front and rear sides of the suction port, the first roller brush has a built-in drive motor, and the first roller brush drives the second roller brush to rotate synchronously through a transmission mechanism.

[0015] Preferably, the transmission mechanism includes a first gear and a second gear connected to the first roller brush and the second roller brush respectively, and the first gear and the second gear are synchronously transmitted through a transmission gear.

[0016] The beneficial effects of this utility model are:

[0017] In this utility model, the scraper removes dust adhering to the surface of the filter screen during use, effectively preventing filter screen blockage and ensuring long-lasting and stable suction. When emptying the ash, the scraper structure can also push the dust off, achieving a more thorough integrated cleaning. During this process, the hands are isolated from the dust inside and out, eliminating the risk of dust allergies and infections.

[0018] This utility model utilizes the flexible design of the soft rubber baffle to efficiently collect dust in the dust collection chamber. The baffle has good deformation ability, which not only facilitates the smooth entry of dust when air is introduced, but also supports the smooth discharge of dust when dust is discharged. It simplifies the air duct structure and eliminates the traditional dust cover opening and closing structure, giving the body the advantage of being lightweight.

[0019] In this invention, the dust collection bin is located near the floor brush, which significantly shortens the air duct path, reduces suction loss, and thus improves dust collection efficiency. At the same time, the dust collection bin and the floor brush adopt a detachable connection structure, allowing users to quickly disassemble and clean up the accumulated dust, making maintenance more convenient and labor-saving.

[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and are not intended to limit this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] like Figure 1 - Figure 10As shown: A stick vacuum cleaner includes a floor brush 1 and a stick body 2. The floor brush 1 includes a base 11, a suction port 12 and an adapter 13, wherein the suction port 12 is located in the middle of the base 11, and the adapter 13 is hinged to the upper end of the base 11. The adapter 13 and the suction port 12 are connected by a flexible hose 14. The stick body 2 is rotatably connected to the floor brush 1 via the adapter 13, which facilitates flexible turning during operation. The stick body 2 is equipped with a vacuum generating device 4 and a dust collection bin 3 communicating with the suction port 12. The vacuum generating device 4 is located inside the stick body 2. It is used to provide suction force for the dust-laden airflow to enter the dust collection bin 3 through the suction port 12. The dust collection bin 3 is located below the stick body 2. The bottom of the dust collection bin 3 is detachably connected to the adapter 13. When the dust collection bin 3 is installed to the adapter 13, it is connected to the hose 14 to form airflow conduction. In order to maximize the capacity of the dust collection bin 3, in this embodiment, the dust collection bin 3 is independently integrated below the stick body 2, and the outer diameter of the two is the same, so that the dust collection bin 3 forms at least a part of the stick body 2. Since the dust collection bin 3 is close to the floor brush 1, the air duct path is shorter, so the suction loss is small and the dust collection efficiency is high.

[0039] Specifically, the vacuum generator 4 is located above the dust collection bin 3 and is connected to the dust collection bin 3. An air outlet 21 is formed on the surface of the rod-shaped body 2 on one side of the vacuum generator 4 to discharge the filtered clean airflow. The vacuum generator 4 is a motor or fan that can generate vacuum suction. A battery pack 22 for powering it is also installed at the upper part of the inside of the rod-shaped body 2. The battery pack 22 uses a rechargeable lithium battery pack. A charging port and a work panel (not shown) are also provided on the surface of the rod-shaped body 2. A control module 23 is also installed at the upper part of the inside of the rod-shaped body 2. The control module 23 has a control button on the outer surface of the body 2. The start and stop of the vacuum generator 4 are controlled by operating the button.

[0040] Furthermore, to facilitate dust cleaning in the dust collection bin 3, a slot 131 is formed on the upper side of the air inlet channel 31. A card plate 310 is connected to the bottom of one side of the dust collection bin 3 via a snap-fit ​​spring 311. The card plate 310 engages with the slot 131 via the snap-fit ​​spring 311. The side of the dust collection bin 3 has a movable space for pressing the card plate 310 inward. In use, the user presses the card plate 310 onto the dust collection bin 3 until it disengages from the slot 131, thus removing the connection between the dust collection bin 3 and the adapter 13.

[0041] Furthermore, a matching plug and socket (not shown) are provided between the upper end of the adapter 13 and the lower end of the dust collection bin 3. When the dust collection bin 3 is plugged into the adapter 13 and locked in place, the socket and plug are connected to form an electrical connection; conversely, when the dust collection bin 3 is removed from the adapter 13, the socket and plug are disconnected.

[0042] Specifically, the lower part of the dust collection bin 3 forms an air inlet channel 31 that connects to the adapter 13, and the upper part of the dust collection bin 3 forms a dust collection chamber 32. A baffle 33 that can be flipped up and down is provided between the air inlet channel 31 and the dust collection chamber 32. A filter screen 34 and a HEPA filter 35 are formed on one side of the dust collection chamber 32 along the axial direction of the rod-type body 2. The filter screen 34 forms a partition between the dust collection chamber 32 and the HEPA filter 35, so that the dust-laden airflow entering the dust collection chamber 32 first passes through the filter screen 34 to filter out large dust particles and then enters the HEPA filter 35 for high-efficiency filtration. The axial arrangement can effectively increase the filtration area and ensure smooth airflow.

[0043] Furthermore, the filter screen 34 and the HEPA filter 35 extend in the axial direction in a rectangular shape and are installed in the dust collection bin 3 by a snap-fit ​​method. The snap-fit ​​method of the filter screen 34 and the HEPA filter 35 in the dust collection bin 3 is a well-known technology in the art and will not be described in detail here. The surface of the filter screen 34 that contacts the dust-laden airflow is a plane.

[0044] Furthermore, to facilitate cleaning of the filter screen 34 surface, the dust collection chamber 32 is also equipped with a scraper 36 for scraping the filter screen 34. The dust collection bucket 3 is equipped with a sliding sleeve 37 for driving the scraper 36 to slide up and down. The scraper 36 has a first adsorption element 361 inside, and the sliding sleeve 37 is equipped with a second adsorption element 371 that can adsorb the first adsorption element 361. In use, the axial sliding of the sliding sleeve 37 outside the dust collection bucket 3, and then the mutual attraction between the second adsorption element 371 and the first adsorption element 361, drives the scraper 36 to scrape off the dust accumulated on the surface of the filter screen 34, preventing the filter screen from clogging and affecting the dust collection effect.

[0045] Furthermore, in order to keep the scraper blade 36 and the sliding sleeve 37 at the top of the dust collection bin 3 when not in use, a third adsorption element 321 that can adsorb the first adsorption element 361 is built into the top of the dust collection chamber 32.

[0046] In a preferred embodiment, the first adsorption element 361 is a positive magnet, the second adsorption element is a negative magnet, and the third adsorption element is an iron block. The positive and negative magnets attract each other, ensuring that the power is stably transmitted to the scraper plate 36 when the sliding sleeve 37 slides. Moreover, the positive and negative magnets can also attract the third adsorption element 321 at the same time, further ensuring the stability of the sliding sleeve 37 and the scraper plate 36 when not in use. To reduce costs, the first adsorption element 361 in this embodiment can also be an iron block. It should be noted that the attraction force of the first adsorption element 361 and the second adsorption element 371 is greater than the attraction force of the first adsorption element 361 and the third adsorption element 321. When the sliding sleeve 37 slides, the attraction force of the second adsorption element 371 and the first adsorption element 361 first overcomes the attraction force of the first adsorption element 361 and the third adsorption element 321, and then the sliding sleeve 37 drives the scraper plate 36 to move synchronously to perform the scraping action.

[0047] Furthermore, a T-shaped slot 38 is formed on one side of the dust collection bin 3. The baffle 33 includes a snap-fit ​​end 331 and a flip-up end 332. The snap-fit ​​end 331 is snapped and fixed in the T-shaped slot 38. When there is no external force, the baffle isolates the air inlet channel 31 from the dust collection chamber 32. Figure 2 As shown in the diagram; under the suction of the vacuum generator 4, the flipping end 332 flips upward relative to the snap-fit ​​end 331, allowing the dust-laden airflow to enter the dust collection chamber 32, which is... Figure 4 As shown in the diagram; when subjected to the downward driving force of the sliding sleeve 37, the flipping end 332 flips downward relative to the snap-fit ​​end 331, and the dust collected in the dust chamber 32 is discharged through the air inlet channel 31, which is... Figure 6 The state shown;

[0048] Furthermore, in order to ensure the overall performance of the baffle 33, the downward force driving the flipping end 332 is greater than the upward force. Under the suction of the vacuum generator 4, the flipping end 332 can be easily opened upward, which facilitates dust collection. Since the downward force is greater, even if a large amount of dust is collected on the baffle 33, it will not automatically open under the gravity of the dust without the downward pushing force of the scraper 36, ensuring that the dust is stably collected in the dust collection chamber 32. It should be noted that the suction force of the first adsorption member 361 and the second adsorption member 371 is greater than the pushing force of the scraper 36 driving the flipping end 332 downward.

[0049] Furthermore, the baffle 33 is made of soft rubber. The snap-fit ​​end 331 and the T-shaped slot 38 are squeezed together to ensure the stable installation of the baffle 33 in the dust collection bin 3. A crease is formed between the snap-fit ​​end 331 and the flip end 332 to facilitate flipping, thereby enabling the flip end 332 to flip up and down. Preferably, the soft rubber material is silicone, which has the characteristics of stable performance, not easy to deform, and good durability.

[0050] Furthermore, in order to ensure the stable sliding of the sliding sleeve 37 outside the dust collection bin 3, two slide rails 39 are formed on the outer side of the dust collection bin 3 along the axial direction. The inner side of the sliding sleeve 37 is provided with a corresponding insert 372 of the slide rail 39. The insert 372 and the slide rail 39 prevent the sliding sleeve 37 from rotating, ensuring that the second adsorption member 371 and the first adsorption member 361 always correspond.

[0051] Specifically, the base 11 is rotatably connected to a first roller brush 15 and a second roller brush 16. The first roller brush 15 and the second roller brush 16 are located on the front and rear sides of the suction port 12, respectively. The first roller brush 15 has a built-in drive motor 151. The first roller brush 15 drives the second roller brush 16 to rotate synchronously through the transmission mechanism 17. The bottom of the base 11 is equipped with a guide plate 18 and casters 19. The guide plate 18 is located on both sides of the suction port 12 and is cone-shaped, so as to guide the airflow on both sides to the suction port 12 for concentrated suction. The casters 19 provide support for the bottom of the vacuum cleaner and facilitate pushing and pulling during use.

[0052] More specifically, a fixed first side cover 111 and a detachable second side cover 112 are respectively installed on the side end of the base 11. The first roller brush 15 and the second roller brush 16 are rotatably connected to the base 11 through the first side cover 111 and the second side cover 112. The drive motor 151 is fixedly installed on the first side cover 111 and its output end is connected to the first roller brush 15, thereby driving the first roller brush 15 to rotate. The second side cover 112 is connected to the base 11 through a snap-fit ​​mechanism. When the snap-fit ​​mechanism is released, the second side cover 112 is detached from the base 11. After removing the second side cover 112, the first roller brush 15 and the second roller brush 16 can be taken out for maintenance or replacement. This is a well-known technology in the art and will not be described in detail here.

[0053] Furthermore, a first wire hole 1111 is provided on the first side cover 111, and a second wire hole 121 is provided on the dust suction port 12. The wires are connected to the drive motor 151 and the plug on the adapter 13 through the first wire hole 1111 and the second wire hole 121, and then connected to the battery pack 22 and the control module 23 through the plug. The battery pack 22 supplies power to the drive motor 151, and the control module 23 controls the start and stop of the drive motor 151. When the wires of the drive motor 151 are arranged, they are close to the inner wall of the dust suction port 12 and the hose 14 to avoid blocking dust collection.

[0054] Furthermore, the transmission mechanism 17 is installed in the second side cover 112. The transmission mechanism 17 includes a first gear 171 and a second gear 172 that are respectively connected to the first roller brush 15 and the second roller brush 16. The first gear 171 and the second gear 172 are synchronously transmitted through the transmission gear 173. The front ends of the first gear 171 and the second gear 172 are provided with non-circular inserts that respectively cooperate with non-circular slots on the first roller brush 15 and the second roller brush 16. The inserts and slots are axially connected to achieve modular disassembly and assembly and stable power transmission.

[0055] One specific application of this embodiment is:

[0056] Vacuuming: During use, the first roller brush 15 and the second roller brush 16 work in tandem to achieve dual cleaning. The drive motor 151 and vacuum generator 4 are simultaneously activated via the button on the control module 23. When the drive motor 151 is working, it rotates the first roller brush 15, which, under the action of the transmission mechanism 17, drives the second roller brush 16 to rotate synchronously. The first and second roller brushes 15 and 16 sweep dust to below the suction port 12. When the vacuum generator 4 is working, it draws in dust-laden airflow from the bottom of the suction port 12 upwards. At this time, the flip end 332 opens upwards under negative pressure. When the airflow is turned on, the dust-laden airflow enters the dust collection chamber 32 through the hose 14, adapter 13, and air inlet channel 31. Under the action of filter screen 34 and HEPA filter 35, the dust particles in the airflow are filtered and the dust is collected in the dust collection chamber 32. After the airflow passes through the HEPA filter 35, it flows to the vacuum generator 4 and finally exits from the air outlet 21. After the dust is collected, the vacuum generator 4 and drive motor 151 are turned off. At this time, the negative pressure disappears, and the flip end 332 is reset under the action of gravity, which isolates the air inlet channel 31 and the dust collection chamber 32, and the dust is collected in the dust collection chamber 32.

[0057] Dust removal: By pressing inward to disengage the card plate 310 from the card slot 131, the locking spring 311 is compressed, and the dust collection bin 3 is pulled out from the adapter 13. At this time, the rod-type body 2 and the dust collection bin 3 are simultaneously removed from the floor brush 1, thus completing the dust removal process. Figure 7 As shown in the diagram; at this time, hold the sliding sleeve 37 and push it down. Under the action of the second adsorption member 371 and the first adsorption member 361, drive the scraper 36 to move down in the dust collection chamber 32. The scraper 36 scrapes the surface of the filter screen 34 and pushes the dust collected in the dust collection chamber 32 toward the baffle 33. The scraper 36 continues to move down, pushing the flip end 332 to flip down, and the dust is discharged downward through the air inlet channel 31.

[0059] 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.
