Description

Technical Field

[0001] This invention belongs to the field of cleaning appliance technology, and in particular relates to a shearing structure that can solve the problem of hair entanglement in cyclone filter devices. Background Technology

[0002] Environmental hygiene is an important factor affecting the quality of life. Therefore, as people’s requirements for quality of life continue to increase, their requirements for environmental hygiene are also getting higher and higher. However, modern people’s work pressure is increasing day by day, and they urgently need to be freed from heavy cleaning work. As a result, many floor cleaning devices have emerged to improve environmental hygiene, such as vacuum cleaners, automatic mops, sweepers and floor scrubbers.

[0003] Nowadays, vacuum cleaners are a very common cleaning device, whether in the industrial field or at home.

[0004] Dust cup filtration separates dust, debris, and gas through a high-speed rotating motor creating a vacuum airflow. The air is then purified using filters such as HEPA filters to prevent secondary pollution. The advantage is that the dust bag doesn't need frequent replacement; the disadvantage is that it needs to be cleaned after each use. Dust cup filtration is currently the primary filtration method in vacuum cleaners, and most vacuum cleaners now use it. It's an upgrade from dust bag filtration, and another advantage is that it requires no consumables, avoiding secondary investment.

[0005] In dust cup filtration, dust and debris are collected in the dust collection chamber under the action of airflow. In order to improve the dust collection effect, the existing technology uses a dust-scraping plate to "scrape the dust" on the outer wall of the cyclone cone to prevent dust accumulation and blockage of the filter holes. This process can simultaneously collect dust and debris at the bottom of the dust collection chamber and press them into a ring shape for easy subsequent processing.

[0006] Chinese invention patent CN 201910279181 discloses a dust cup cleaning assembly and a vacuum cleaner having the same. The dust cup cleaning assembly includes: a dust cup with a through hole; a cyclone filter disposed inside the dust cup; and a scraper movable between a first position and a second position. When the scraper is in the first position, it at least partially passes through the through hole and abuts against the peripheral wall of the cyclone filter, and the cyclone filter and the scraper are movable relative to each other. When the scraper is in the second position, it is separated from the cyclone filter.

[0007] This invention patent proposes using a scraper to clean dust and hair from a filter screen. Dust can be removed by the relative movement of the scraper and the cyclone filter screen; however, hair (especially long hair) is often tightly bound to the outer wall of the filter screen in a tangled manner, making it difficult to remove the hair tangled on the outer wall of the filter screen by the relative movement of the scraper and the cyclone filter screen.

[0008] Chinese utility model patent CN 209489959 discloses a dust cup for a vacuum cleaner, comprising: a dust cup outer shell with an annular inner circumferential wall; a dust cup inner shell fixed inside the dust cup outer shell, having an annular outer circumferential wall and densely covered with dust filter holes; and a vertically arranged annular dust collection chamber formed between the annular outer circumferential wall of the dust cup outer shell and the annular inner circumferential wall of the dust cup inner shell; a circular dust-pressing plate, sleeved on the outer side of the dust cup inner shell and capable of moving up and down, is arranged in the dust collection chamber; and a flexible bristle is fixed around the periphery of the dust-pressing plate, which flexibly abuts against the annular inner circumferential wall of the dust cup outer shell.

[0009] This utility model patent proposes to clean dust from the outer wall of the dust cup inner cylinder and the inner wall of the dust cup outer barrel by setting flexible bristles on both the inner and outer rings of the annular dust pressing plate; however, it is difficult to remove hair tightly wrapped around the outer wall of the cyclone cone by relying solely on these flexible bristles.

[0010] The problems faced:

[0011] During vacuum cleaner use, hair that falls on the floor and in corners is sucked into the dust cup. Long hair, in particular, tends to become tightly entangled on the outer wall of the cyclone cone. This tightly entangled hair cannot be effectively cleaned using current technology, leading to cleaning difficulties and clogging of the cyclone cone filter. Furthermore, most handheld rechargeable vacuum cleaners on the market currently allow hair to become entangled in the cyclone filter during operation, requiring manual disassembly of the cyclone unit, which is very difficult for users to clean and also gets their hands dirty. Summary of the Invention

[0012] This invention provides a cutting structure that solves the problem of hair entanglement in cyclone filters. By installing a cutting component on the dust cup, the dust cup and the cyclone filter are in a relative motion state when the dust cup is disassembled. The cutting component can cut off the hair entangled on the cyclone filter without disassembling the cyclone filter, which is more convenient and improves the user experience.

[0015] A dust cup, one end of which is connected to the cyclone filter device, and the filter screen is located inside the dust cup;

[0016] A cutting component is attached to the dust cup and contacts the outer surface of the filter screen. When the dust cup is separated from the cyclone filter device and pulled out, the cutting component cuts the hair wrapped around the filter screen.

[0017] As a further description of the above technical solution:

[0018] The dust cup includes a cup body and a first sealing ring. One end of the cup body is inserted into the cyclone filter device, and the other end of the cup body is connected to the vacuum cleaner body through a button assembly.

[0021] As a further description of the above technical solution:

[0022] The cutting component is connected to the first sealing ring, which is inserted into the gap between the cup body and the cyclone filter device.

[0023] As a further description of the above technical solution:

[0024] The cutting component includes a circular plate and several cutting sections. The circular plate has through holes that are adapted to the size of the filter screen. The several cutting sections are arranged at intervals along the circumference of the circular plate.

[0025] As a further description of the above technical solution:

[0026] The filter screen has a groove corresponding to the position of the cutting part, and the groove is arranged along the axial direction of the filter screen. The cutting part is a blade or a plastic sheet.

[0027] As a further description of the above technical solution:

[0028] The button assembly includes a button base, a button, a first spring, a second spring, and a retainer. The button base is connected to the cup body, and the button is movably connected to the button base. One end of the first spring is connected to the button, and the other end of the first spring is connected to the button base. The retainer is vertically arranged and movably connected to the button base. One end of the second spring is connected to the bottom of the retainer, and the other end of the second spring is connected to the button base. When the button is pressed, the button causes the retainer to move downward.

[0032] The cup body is provided with a hanging part, the vacuum cleaner body is provided on the hanging part, the vacuum cleaner body is provided with sliding grooves on both sides, and the hanging part is provided with a slider at the corresponding position, the slider being slidably connected in the sliding groove.

[0033] As a further description of the above technical solution:

[0034] The vacuum cleaner body is equipped with a suction pipe, the end of which has a bend that is connected to the air inlet on the cup body.

[0035] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0036] 1. The present invention provides a cutting structure for solving the problem of hair entanglement in cyclone filters. The attachment part on the dust cup is sleeved on the vacuum cleaner body. The sliders on both sides of the attachment part are slidably connected in the slide groove, which can fix the dust cup and prevent the dust cup from rotating, making the dust cup more stable. One end of the dust cup is inserted into the cyclone filter, and the other end of the dust cup is snapped onto the vacuum cleaner body through a button assembly. Pressing the button assembly releases the dust cup from the vacuum cleaner body. Pulling the dust cup moves it to the right along the slide groove. At this time, the cutting part connected to the dust cup moves relative to the dust cup and the cyclone filter, thereby cutting off the hair on the cyclone filter and putting it into the dust cup. Then, the dust cup cover is opened to pour out the cut hair and other garbage, completing the cleaning. No manual cleaning is required, achieving the purpose of quick and hygienic cleaning.

[0037] 2. In the cutting structure provided by this invention to solve the problem of hair entanglement in a cyclone filter device, the dust cup is connected to the vacuum cleaner body via a button assembly. By pressing the button assembly, the dust cup can be quickly released. That is, pressing the button moves towards the mounting base and compresses the first spring. The second inclined surface on the button contacts the first inclined surface and presses down on the mounting base, causing the mounting base to compress the second spring and separate from the insertion hole. Releasing the button resets the first spring. During the dust cup disassembly process, when the mounting base passes another insertion hole, the mounting base is pushed upward under the action of the second spring and enters the other insertion hole, which serves to fix the dust cup. During the process of the mounting base moving from one insertion hole to another insertion hole, the cutting part just slides over the filter screen to complete the hair cutting. At this time, the dust cup is not completely separated from the cyclone filter device, which can prevent hair from popping out of the dust cup. Afterwards, press the button again until the dust cup is removed and the cut hair and other garbage are poured out. Attached Figure Description

[0057] Dust cup 3, one end of which is connected to the cyclone filter device 1, and the filter screen 2 is located inside the dust cup 3;

[0058] The cutting component 4 is in contact with the outer surface of the filter screen 2 and is connected to the dust cup 3. When the dust cup 3 is separated from the cyclone filter device 1 and pulled out, the cutting component 4 cuts off the hair wrapped around the filter screen 2.

[0059] This invention provides a cutting structure to solve the problem of hair entanglement in cyclone filters. It mainly consists of a cyclone filter with a filter screen; a dust cup with one end connected to the cyclone filter and the filter screen located inside the dust cup; and a cutting component that contacts the outer surface of the filter screen and is connected to the dust cup.

[0060] With the above-described structure, by installing a cutting part on the dust cup, the dust cup and the cyclone filter are in a relative motion state when the dust cup is disassembled. The cutting part can cut off the hair wrapped around the cyclone filter without disassembling the cyclone filter, which is more convenient and improves the user experience.

[0061] Example 2:

[0062] See Figures 1 to 8The figure shows a cutting structure provided by Embodiment 2 of the present invention to solve the problem of hair entanglement in a cyclone filter device. The cyclone filter device 1 is provided with a filter screen 2; a dust cup 3 is connected at one end to the cyclone filter device 1, and the filter screen 2 is located inside the dust cup 3; a cutting component 4 is in contact with the outer surface of the filter screen 2 and is connected to the dust cup 3. When the dust cup 3 is separated from the cyclone filter device 1 and pulled out, the cutting component 4 cuts the hair entangled on the filter screen 2.

[0063] Based on the above embodiments, this embodiment further improves the following technical solution: The dust cup 3 includes a cup body 31 and a first sealing ring 32. One end of the cup body 31 is inserted into the cyclone filter device 1, and the other end of the cup body 31 is connected to the vacuum cleaner body 6 through the button assembly 5. The first sealing ring 32 is located in the gap between the cup body 31 and the cyclone filter device 1.

[0064] With the above structure, one end of the cup body 31 is inserted into the cyclone filter device 1, and the other end of the cup body 31 is connected to the vacuum cleaner body 6 through the button assembly 5. This makes it easy to disassemble the cup body and reduces the difficulty of operation for users. The first sealing ring can improve the sealing effect and prevent air leakage.

[0065] To improve the sealing effect, specifically, one end of the cup body 31 has a first connecting part 311 and a second connecting part 312. The first connecting part 311 is connected to the outer surface of the cyclone filter device 1, and the second connecting part 312 is connected to the part on the cyclone filter device 1 where the filter screen is installed. The first sealing ring 32 is located between the second connecting part 312 and the cyclone filter device 1, which can improve the stability of the cup body connection.

The cyclone filter device 1 has a filter screen 2; a dust cup 3, one end of which is connected to the cyclone filter device 1, with the filter screen 2 located inside the dust cup 3; and a cutting component 4, which contacts the outer surface of the filter screen 2 and is connected to the dust cup 3. When the dust cup 3 is separated from the cyclone filter device 1 and pulled out, the cutting component 4 cuts the hair entangled on the filter screen 2. The dust cup 3 includes a cup body 31 and a first sealing ring 32. One end of the cup body 31 is inserted into the cyclone filter device 1, and the other end is connected to the vacuum cleaner body 6 via a button assembly 5. The first sealing ring 32 is located in the gap between the cup body 31 and the cyclone filter device 1.

[0068] Based on the above embodiments, this embodiment further improves upon the following technical solution: a second sealing ring 313 is provided between the second connecting part 312 and the cyclone filter device 1.

[0069] With the above structure, the second sealing ring can achieve a sealing effect again, and the first sealing ring and the second sealing ring can form a double sealing effect.

[0070] The second sealing ring 313 is fitted into the sealing ring mounting groove 314 on the cyclone filter device 1 to prevent the second sealing ring from moving. At the same time, the second sealing ring is provided with three limiting posts 315, which are inserted into the corresponding holes on the cyclone filter device 1 to further improve the stability of the second sealing ring. The second sealing ring 313 is provided with a clearance groove 316 in the middle along its circumference. When the vacuum cleaner is working, the pressure change on both sides of the protrusion on the side of the clearance groove 316 away from the dust cup is not significant. Therefore, the clearance groove can play the role of balancing the pressure and improving the sealing effect of the second sealing ring.

[0074] With the above structure, when the dust cup is removed, the cutting part 4 can be moved. The cutting part can cut off the hair wrapped around the cyclone filter without disassembling the cyclone filter, which is more convenient and improves the user experience.

[0075] The cutting component can be fixedly connected to the dust cup, which can improve the stability of the cutting part connection; in another embodiment, the cutting component can be detachably connected to the dust cup by screws, which facilitates the installation, disassembly and replacement of the cutting part.

[0088] Example 8:

[0089] See Figures 1 to 8 The figure shows a cutting structure provided in Embodiment 8 of the present invention to solve the problem of hair entanglement in a cyclone filter device. The cyclone filter device 1 has a filter screen 2; a dust cup 3, one end of which is connected to the cyclone filter device 1, with the filter screen 2 located inside the dust cup 3; and a cutting component 4, which contacts the outer surface of the filter screen 2 and is connected to the dust cup 3.

The plurality of cutting parts 42 are arranged at intervals along the circumference of the circular plate 41.

[0090] Based on the above embodiments, this embodiment further improves upon the following technical solutions: The button assembly 5 includes a button base 51, a button 52, a first spring 53, a second spring 54, and a retainer 55. The button base 51 is connected to the cup body 31, the button 52 is movably connected to the button base 51, one end of the first spring 53 is connected to the button 52, and the other end of the first spring 53 is connected to the button base 51. The retainer 55 is vertically arranged and movably connected to the button base 51. The bottom of the retainer 55 is connected to one end of the second spring 54, and the other end of the second spring 54 is connected to the button base 51. When the button 52 is pressed, the button 52 causes the retainer 55 to move downward. The vacuum cleaner body 6 is provided with a plug hole 8. The top of the card holder 55 is inserted into the plug hole 8. A baffle 9 is provided on one side below the plug hole 8. The baffle 9 abuts against the side of the card holder 55. The card holder 55 has a limiting hole 10. The limiting hole 10 has a first inclined surface 11 on the side facing the button 52. The end of the button 52 has a second inclined surface 12 that matches the first inclined surface 11.

[0091] With the above-described structure, the dust cup can be quickly released by pressing the button assembly. Pressing the button moves the button toward the card holder and compresses the first spring. The second inclined surface on the button contacts the first inclined surface and presses down on the card holder, causing the card holder to compress the second spring and separate from the insertion hole. Releasing the button resets the first spring. During the dust cup disassembly process, when the card holder passes another insertion hole, the card holder is pushed upward by the second spring and enters the other insertion hole, thus fixing the dust cup. During the process of the card holder moving from one insertion hole to another, the cutting part just slides over the filter screen, completing the hair cutting.

[0092] The cup body 31 is provided with a hanging part 13, the vacuum cleaner body 6 is inserted through the hanging part 13, the vacuum cleaner body 6 is provided with sliding grooves 14 on both sides, and the hanging part 13 is provided with a slider 15 at the corresponding position, and the slider 15 is slidably connected in the sliding groove 14.

[0093] The above-described structure can improve the stability of the cup body.

[0094] The vacuum cleaner body 6 is equipped with a suction pipe 16, the end of which has a bend 17, which is connected to the air inlet 18 on the cup body 31. This prevents the suction pipe from being impacted and improves its service life.

[0095] Working principle: The attachment part on the dust cup is fitted onto the vacuum cleaner body. The sliders on both sides of the attachment part slide within the groove, which can fix the dust cup and prevent it from rotating, making the dust cup more stable. One end of the dust cup is inserted into the cyclone filter, and the other end of the dust cup is snapped onto the vacuum cleaner body via a button assembly. Pressing the button assembly releases the dust cup from the vacuum cleaner body. Pulling the dust cup moves it to the right along the groove. At this time, the cutting part connected to the dust cup moves relative to the cyclone filter, thereby cutting off the hair on the cyclone filter and collecting it in the dust cup. Then, open the dust cup cover and empty the cut hair and other debris to complete the cleaning. No manual cleaning is required, achieving the purpose of quick and hygienic cleaning. The dust cup is connected to the vacuum cleaner body via a button assembly. Pressing the button assembly allows for quick release of the dust cup. Pressing the button moves it toward the mounting bracket and compresses the first spring. The second inclined surface on the button contacts the first inclined surface and presses down on the mounting bracket, causing it to compress the second spring and separate from the insertion hole. Releasing the button returns the first spring to its original position. During dust cup disassembly, as the mounting bracket passes another insertion hole, it is pushed upward by the second spring and enters the other insertion hole, thus securing the dust cup. As the mounting bracket moves from one insertion hole to another, the cutting part slides over the filter screen, cutting the hair. At this point, the dust cup is not completely separated from the cyclone filter, preventing hair from popping out of the dust cup. Afterward, press the button again until the dust cup is removed, and the cut hair and other debris can be emptied.
