The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order; the cold water mentioned in the specification and claims of this invention includes room temperature water.

[0031] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] Reference Figures 1 to 3 The first embodiment of this application proposes a dust collection cylinder 100, which is provided with a dust collection cylinder hole 110 and a plurality of dust collection mesh holes 120. The dust collection cylinder hole 110 is used to connect to the air outlet of the dust collection drive component 2000; the dust collection mesh holes 120 are connected to the dust collection cylinder hole 110; and the dust collection mesh holes 120 are strip-shaped holes.

[0034] In this embodiment, the suction cylinder 100 is located at the air outlet of the suction drive 2000 and is used to filter and collect debris from the location to be vacuumed. The suction cylinder opening 110 allows the suction force generated by the suction drive 2000 to pass through, thereby guiding dust and debris into the suction cylinder 100. It also allows the blowing force generated by the suction drive 2000 to pass through, thereby using this blowing force to blow away thin, elongated debris wrapped around the suction mesh opening 120 to the designated debris collection area. The suction mesh opening 120 guides dust and relatively short debris into the suction cylinder opening 110, where the collection device collects the debris. This also prevents larger items from being sucked into the suction cylinder opening 110, thus avoiding clogging of the suction cylinder opening 110.

[0035] The 120 mesh openings are strip-shaped, increasing the suction area and improving suction efficiency; they also expand the range of large debris that can be sucked up, reducing the risk of clogging and making the suction process smoother.

[0036] Reference Figures 1 to 3 The dust collection mesh 120 includes a first branch hole 121, a second branch hole 122, and a third branch hole 123; one axial end of the first branch hole 121, one axial end of the second branch hole 122, and one axial end of the third branch hole 123 are all connected to the dust collection cylinder hole 110. The first branch hole 121 and the third branch hole 123 are both semi-circular holes, and the second branch hole 122 is a rectangular hole. The two short ends of the second branch hole 122 are respectively connected to the straight side end of the first branch hole 121 and the straight side end of the third branch hole 123.

[0037] In this embodiment, the suction area is increased by using the first branch hole 121, the second branch hole 122, and the third branch hole 123; and since the first branch hole 121 and the third branch hole 123 are both semi-circular holes, while the second branch hole 122 is a rectangular hole, the suction screen cylinder 100 can better adapt to dust and debris of different sizes and shapes; and the first branch hole 121, the second branch hole 122, and the third branch hole 123 facilitate the dispersion of debris, thereby helping to reduce the risk of clogging.

[0038] Specifically, the dust collection mesh 120 has long, racetrack-shaped holes.

[0039] Reference Figures 1 to 3 The long side of the second branch hole 122 forms a first included angle D1 with the vertical line, and the degree range of the first included angle D1 is 0-60 degrees.

[0040] In this embodiment, by adjusting the degree of the first included angle D1, the airflow path can be optimized, allowing dust or debris to pass more smoothly through the suction mesh 120, reducing eddies and turbulence, and improving suction efficiency.

[0041] Reference Figure 3 The distance between the two long sides of the second branch hole 122 is less than 0.5 mm, and the distance between the rounded top end of the first branch hole 121 and the rounded top end of the third branch hole 123 is greater than 1 mm.

[0042] In this embodiment, the distance between the two long sides of the second branch hole 122 is L1, where L1 < 0.5 mm, which helps to reduce air leakage during the vacuuming process. The distance from the rounded top of the first branch hole 121 to the rounded top of the third branch hole 123 is L2, where L2 > 1 mm. By adjusting the size of L2, the vacuum cleaner cylinder 100 can be made more adaptable to different vacuuming needs.

[0043] Reference Figures 4 to 9 The second embodiment of this utility model provides a vacuum cleaner cup for a vacuum cleaner, the vacuum cleaner cup including the aforementioned vacuum cleaner mesh cylinder 100 and frame body 200; the frame body 200 includes a bottom frame 210 and a top frame 220; the bottom frame 210 is fixedly mounted on the bottom end of the vacuum cleaner mesh cylinder 100, the top frame 220 is fixedly mounted on the top end of the vacuum cleaner mesh cylinder 100, the top frame 220 is provided with a connecting vacuum hole 221, the bottom end of the connecting vacuum hole 221 is connected to the top end of the vacuum cleaner mesh hole 120, and the top end of the connecting vacuum hole 221 is used to connect to the air outlet of the vacuum drive component 2000.

[0044] In this embodiment, the dust collection cylinder 100 is used to filter and collect dust and debris; the bottom frame 210 and the top frame 220 not only provide support and protection for the dust collection cylinder 100, but also ensure the overall structural stability of the dust collection cup; the connecting dust collection hole 221 serves as a connecting channel between the air outlet of the dust collection drive 2000 and the dust collection cylinder 100, ensuring that the airflow can smoothly enter the dust collection cylinder 100 for dust collection operations.

[0045] Reference Figures 4 to 9 The bottom frame 210 is provided with a first groove 211, and the bottom end of the dust collection net cylinder 100 is embedded in the first groove 211.

[0046] In this embodiment, the first groove 211 is used to achieve a stable connection between the dust collection cylinder 100 and the bottom frame 210, preventing the dust collection cylinder 100 from loosening or shifting during use, thereby ensuring the overall structural stability of the dust collection cup.

[0047] Reference Figures 4 to 7The frame body 200 further includes a first connecting frame 230 and a second connecting frame 240. The two ends of the first connecting frame 230 are respectively fixed to the bottom frame 210 and the top frame 220; the bottom end of the second connecting frame 240 is fixed to the bottom frame 210. The first connecting frame 230 and the second connecting frame 240 are spaced apart. The top end of the second connecting frame 240 is spaced apart from the wall of the connecting dust suction hole 221. The tube plate of the dust suction net cylinder 100 is located between the first connecting frame 230 and the second connecting frame 240.

[0048] In this embodiment, the first connecting frame 230 provides additional stable support for the vacuum cup. Furthermore, the spacing between the first connecting frame 230 and the second connecting frame 240 ensures a stable installation between the frame body 200 and the vacuum filter cylinder 100, further preventing the vacuum filter cylinder 100 from loosening or shifting during use. Then, the spacing between the top of the second connecting frame 240 and the wall of the connecting vacuum hole 221 facilitates a detachable installation between the vacuum filter cylinder 100 and the frame body 200.

[0049] Specifically, the first connecting frame 230 and the second connecting frame 240 are spaced apart to form a mesh cylinder installation area 250.

[0050] Reference Figures 4 to 6 The top frame 220 includes an inner top frame 222 and an outer top frame 223; the outer top frame 223 is provided with a mounting hole 2231, the bottom end of the inner top frame 222 is inserted into the mounting hole 2231, the top end of the inner top frame 222 is sealed and embedded in the top end of the outer top frame 223, the dust collection hole 221 is provided in the inner top frame 222, and the bottom end of the inner top frame 222 is used to press the tube plate of the dust collection net cylinder 100 against the hole wall of the mounting hole 2231.

[0051] In this embodiment, the inner top frame 222 and the outer top frame 223 ensure the sealing of the inside of the top frame 220, preventing air leakage during the vacuuming process. They also further ensure the stable installation of the vacuum cleaner cylinder 100. Furthermore, the tightening effect at the bottom of the inner top frame 222 reduces the vibration and displacement of the vacuum cleaner cylinder 100 during the vacuuming process.

[0052] Reference Figures 4 to 6 The mounting hole 2231 has a limiting protrusion 2232 on its hole wall. The limiting protrusion 2232 is used to press against the outer wall of the dust collection net cylinder 100 or to pass through the dust collection net hole 120.

[0053] In this embodiment, the limiting protrusion 2232 is used to ensure the stability of the dust collection cylinder 100 within the mounting hole 2231, preventing it from loosening or shifting during the dust collection process.

[0054] Reference Figures 4 to 6 The vacuum cleaner cup also includes a filter assembly 300; the filter assembly 300 includes a filter bracket 310, a first filter connecting bracket 320, a second filter connecting bracket 330, and a HEPA filter element 340; the filter bracket 310 is provided with a main suction hole 311 and a plurality of filter perforations 312, the first end of the filter perforation 312 is connected to the main suction hole 311, and the main suction hole 311 is used to connect to the air outlet of the vacuum drive unit 2000; the first filter connecting bracket 320 is fixed to the top of the filter bracket 310, the second filter connecting bracket 330 is fixed to the bottom of the filter bracket 310, and the two ends of the HEPA filter element 340 are respectively fixed to the first filter connecting bracket 320 and the second filter connecting bracket 330; the HEPA filter element 340 is located between the connecting suction hole 221 and the second end of the filter perforation 312.

[0055] In this embodiment, the HEPA filter 340, as the core component of the filter assembly 300, is capable of capturing tiny particulate matter in the air, such as dust, pollen, and bacteria. Through the filtration function of the HEPA filter 340, the airflow discharged from the exhaust port of the vacuum drive unit 2000 is ensured to be clean, thereby avoiding secondary pollution to the environment. The filter bracket 310, the first filter connecting bracket 320, and the second filter connecting bracket 330 all serve as supporting structures, providing stable support for the HEPA filter 340 and preventing it from shifting or deforming during vacuuming.
