[0042] The dust leakage prevention dust collection assembly and the vacuum cleaner 100 according to the embodiments of the present utility model will be described below with reference to the drawings.

[0043] As Figures 1-5 shown, the dust leakage prevention dust collection assembly according to the embodiments of the present utility model includes: a main body 10, a dust chamber cover 20, a dust collection bag, and a limiting member 40. A dust collection chamber 11 is formed inside the main body 10, and the dust collection chamber 11 has an opening 12. The dust chamber cover 20 is detachably provided at the opening 12. The dust collection bag has an installation position inside the dust collection chamber 11, and the dust collection bag is detachably provided at the installation position. The limiting member 40 is provided inside the dust collection chamber 11, and the limiting member 40 has a first state and a second state;

[0044] wherein, the limiting member 40 abuts against the dust chamber cover 20 in the first state to block the dust chamber cover 20 from covering the opening 12; when the dust collection bag is in the installation position, the limiting member 40 is in the second state to avoid the dust chamber cover 20.

[0045] Thus, when the dust bag is not installed at the installation position, the stopper 40 can block the closing of the dust chamber cover 20 at the opening 12 in the first state. When the dust bag is installed at the installation position, the stopper 40 can be in the second state, so that the dust chamber cover 20 can smoothly cover the opening 12. In other words, whether the closing of the opening 12 of the dust chamber cover 20 is blocked by the stopper 40, that is, whether the dust chamber cover 20 can completely cover the opening 12, can serve as a reminder of whether the dust bag is correctly installed at the installation position.

[0046] The anti-leaking dust collection assembly of the present application, when the dust bag is not installed to the installation position, the closing of the dust chamber cover 20 on the opening 12 can be blocked by the limit member 40, thereby reminding the user that the dust bag has not been correctly installed to the installation position, reducing or avoiding the missing or wrong installation of the dust bag in the dust chamber 11, and improving the reliability of the use of the dust bag.

[0047] In some embodiments, Figures 1-5 As shown, the limiting member 40 has a movable stop end 421, and the stop end 421 has a stop position and an avoidance position.

[0048] When the limiting member 40 is in the first state, the stop end 421 is located at the stop position, and the stop end 421 stops at the dust chamber cover 20 to prevent the dust chamber cover 20 from covering the opening 12, thereby realizing the reminder function that the dust bag is not installed at the installation position or the dust bag is missing.

[0049] When the stopper 40 is in the second state, the stopper end 421 is located at the avoidance position, and the stopper end 421 avoids the dust chamber cover 20. The dust bag is pressed on the stopper 40 in the installation position, so that the stopper 40 remains in the second state, ensuring that the dust chamber cover 20 covers the opening 12 smoothly, so that the dust chamber cover 20 can cover the opening 12 completely.

[0050] In some embodiments, Figure 3 , Figures 5-8 As shown, the limiting member 40 includes: a fixing frame 41 and a limiting rod 42. The fixing frame 41 is connected to the body 10, and the limiting rod 42 is movably connected to the fixing frame 41. One end of the limiting frame forms a stop end 421, and the other end forms a driving end 422. The dust bag is pressed on the driving end 422 when in the installation position, so that the stop end 421 is located in the avoidance position.

[0051] Thus, the limiting member 40 is connected to the main body 10 through the fixing bracket 41, so that the installation position of the limiting member 40 on the main body 10 is stable, ensuring that the dust collection bag can stably contact the driving end 422 of the limiting rod 42 at the installation position. The limiting rod 42 is a rigid structure. When the dust collection bag presses on the driving end 422 at the installation position, the driving end 422 is stressed and moves, thereby driving the whole limiting rod 42 to move or rotate. Furthermore, the position of the stopping end 421 also moves, causing the stopping end 421 to move to the avoidance position.

[0052] Meanwhile, the dust collection bag remains pressed on the driving end 422 at the installation position, enabling the stopping end 421 to stay in the avoidance position, so that the dust chamber cover 20 can be smoothly and completely closed on the opening 12.

[0053] In this application, the movement mode of the limiting rod 42, that is, the mode in which the driving end 422 drives the stopping end 421 to move, is not limited. For example, in Figures 6-8 the example, the limiting rod 42 is rotatably connected to the fixing bracket 41. When the dust collection bag presses on the driving end 422, the driving end 422 rotates around the rotation axis of the limiting rod 42, causing the stopping end 421 to rotate synchronously around the rotation axis of the limiting rod 42, realizing the movement of the position of the stopping end 421. Another example is that the limiting rod 42 is movably connected to the fixing bracket 41. When the dust collection bag presses on the driving end 422, the driving end 422 moves along the pressure direction of the dust collection bag on it, and the stopping end 421 moves in the same direction as the driving end 422, thereby realizing the movement of the position of the stopping end 421.

[0054] Furthermore, the limiting rod 42 is provided with a first rotating part 425, and the fixing bracket 41 is provided with a second rotating part 426. The first rotating part 425 is rotationally matched with the second rotating part 426 to realize the rotational connection of the limiting rod 42 on the fixing bracket 41. Among them, the first rotating part 425 is located between the stopping end 421 and the driving end 422.

[0055] Thus, the limiting rod 42 forms a lever structure. The position of the first rotating part 425 forms the fulcrum of the lever. The stopping end 421 and the driving end 422 are located on both sides of the fulcrum, making the force on both sides of the fulcrum of the limiting rod 42 more uniform, which can improve the structural stability of the limiting rod 42 and the stability of the movement of the position of the stopping end 421. Thereby enabling the stopping end 421 to more stably block the dust chamber cover 20 at the stopping position and more stably avoid the dust chamber cover 20 at the avoidance position, improving the reliability and stability of the limiting rod 42.

[0056] Furthermore, as Figures 6-8 shown, the first rotating part 425 is a convex column, and the second rotating part 426 is a rotating hole. Or, the first rotating part 425 is a rotating hole, and the second rotating part 426 is a convex column. The convex column is rotatably inserted into the rotating hole.

[0057] Thus, the installation method of the convex post inserted into the rotation hole is relatively simple, and there is no need to provide additional structures such as bearings or rotating shafts between the limiting rod 42 and the fixing frame 41, which can facilitate the connection of the limiting rod 42 to the fixing frame 41, simplify the overall structure of the limiting member 40, reduce the manufacturing cost of the limiting member 40, and simplify the installation operation of the limiting rod 42 on the fixing frame 41.

[0058] Preferably, the limiting rod 42 is integrally injection-molded, and the fixing frame 41 is integrally injection-molded. Thus, the convex post is integrally injection-molded on the limiting rod 42, and the rotation hole is integrally injection-molded on the fixing frame 41, which can simplify the setting cost of the convex post and the rotation hole, and can maintain the connection reliability of the convex post on the limiting rod 42. Therefore, while reducing the manufacturing costs of the limiting rod 42 and the fixing frame 41, the stability and reliability of the connection of the limiting rod 42 to the fixing frame 41 can be improved.

[0059] In some embodiments, as Figure 3 、 Figures 5-8 shown, the limiting member 40 further includes: an elastic member 43, and the elastic member 43 is connected to the driving end 422 to drive the stopping end 421 to move towards the stopping position.

[0060] It can be understood that when the dust collection bag is in the installation position, the dust collection bag presses on the driving end 422, enabling the driving end 422 to move against the pressure of the elastic member 43, so that the stopper moves from the stopping position to the avoiding position. When the dust collection bag leaves the installation position or is not in the installation position, the driving end 422 is not pressed by the dust collection bag, causing the driving end 422 to move under the drive of the elastic member 43, moving the stopping end 421 to the stopping position and remaining in the stopping position.

[0061] Thus, when the dust collection bag is not in the installation position, the elastic member 43 can provide a stable driving force to the driving end 422, enabling the stopping end 421 to remain in the stopping position. When the dust collection bag is not installed in the installation position, the stopping end 421 can stably be in the stopping position, providing a stable block to the closing of the dust chamber cover 20 at the opening 12. Therefore, it can more reliably remind the user that the dust collection bag has not been correctly installed in the installation position, reducing or avoiding the omission or misinstallation of the dust collection bag in the dust collection chamber 11.

[0062] Further, the elastic member 43 is a spring, the driving end 422 is provided with a positioning structure 427, and one end of the spring is sleeved on the positioning structure 427. The fixing frame 41 is provided with a positioning hole 428, and the other end of the spring is located in the positioning hole 428.

[0063] Thus, the positioning structure 427 and the positioning hole 428 can define the installation positions of both ends of the spring, making the installation position of the spring limiting member 40 and the axial position of the spring more stable, thereby improving the stability of the direction and magnitude of the force exerted by the spring on the driving end 422, and making the movement of the entire limiting member 40 more stable. When the dust collection bag is not in the installation position, the stop end 421 is more stably located at the stop position.

[0064] Preferably, the positioning structure 427 is arranged as a positioning post.

[0065] In some embodiments, as Figure 3 , Figures 5-8 shown, the limiting rod 42 includes a connecting section 423, the connecting section 423 is movably connected to the fixing frame 41, and the stop end 421 and the driving end 422 are located at both ends of the connecting section 423.

[0066] Thus, the driving end 422 drives the stop end 421 to move through the connecting section 423. The stop end 421 is formed as a protrusion protruding toward the opening 12 at the end of the connecting section 423, making the stop end 421 the position of the limiting rod 42 closest to the opening 12, reducing or avoiding the limiting rod 42 contacting the dust chamber cover 20 at positions other than the stop end 421 and thus affecting the closing of the dust chamber cover 20 at the opening 12. At the same time, the stop end 421 can be adjacent to the opening 12 at the stop position, facilitating the stop end 421 to block the opening 12.

[0067] Furthermore, the stop end 421 and the connecting section 423 are connected by an arc section 424, enabling the stop end 421 to be staggered from the connecting section 423, increasing the distance between the connecting section 423 and the dust chamber cover 20, and further reducing or avoiding the limiting rod 42 contacting the dust chamber cover 20 at positions other than the stop end 421 and thus affecting the closing of the dust chamber cover 20 at the opening 12. At the same time, the pressure received at the stop end 421 can be more evenly transmitted to the connecting section 423 through the arc section 424, which is beneficial to improving the overall structural stability of the limiting rod 42.

[0068] In some embodiments, as Figures 2-5 shown, the dust chamber cover 20 includes a baffle 21. When the dust chamber cover 20 is closed on the opening 12, the baffle 21 extends into the dust collection chamber 11.

[0069] It can be understood that, as Figure 3 shown, when the stop end 421 is at the stop position, the baffle 21 abuts against the stop end 421 along the closing direction of the dust chamber cover 20, blocking the baffle 21 from being completely located within the dust collection chamber 11, so that the dust collection cover cannot be completely closed on the opening. As Figure 5 shown, when the stop end 421 is at the avoidance position, the stop end 421 avoids the baffle 21, enabling the baffle 21 to be completely located within the dust collection chamber 11, and the dust collection cover can be completely closed on the opening 12.

[0070] Thus, the dust chamber cover 20 and the limiting member 40 can cooperate within the dust collection chamber 11, reducing or avoiding the blocking of the limiting member 40 by other structures during its movement at the opening 12, increasing the movement space of the limiting member 40, and improving the reliability and stability of the cooperation between the stopping end 421 and the dust chamber cover 20.

[0071] In some embodiments, the driving end 422 is a boss formed by protruding from the end of the connecting section 423 away from the fixing frame 41. When the dust collection bag is pressed on the driving end 422, the gap between the dust collection bag and the connecting section 423 can be increased, thereby reducing or avoiding the blocking of the installation position of the dust collection bag by the connecting end, and improving the stability and reliability of the dust collection bag pressing on the driving end 422 at the installation position.

[0072] In some embodiments, as Figure 3 , Figure 5 , Figure 9 and Figure 10 shown, the main body 10 is provided with an installation groove 13, and the limiting member 40 is inserted and matched in the installation groove 13. Thus, the installation groove 13 can limit the connection position of the limiting member 40 on the main body 10 and simplify the installation operation of the limiting member 40 on the main body 10.

[0073] Furthermore, two opposite installation ribs 14 are provided on the inner wall of the dust collection chamber 11, and the installation groove 13 is formed between the two installation ribs 14. As Figure 10 shown, the fixing frame 41 is provided with a buckle 44, and the installation rib 14 is provided with a card hole 141 that cooperates with the buckle 44. Alternatively, the fixing frame 41 is provided with a card hole 141, and the installation rib 14 is provided with a buckle 44 that cooperates with the card hole 141.

[0074] Thus, the setting position of the limiting member 40 in the installation groove 13 can be limited, and the stability of the setting position of the limiting member 40 can be improved. At the same time, the cooperation between the card hole 141 and the buckle 44 can achieve a detachable connection, that is, the detachable connection of the limiting member 40 on the main body 10.

[0075] In some embodiments, as Figure 9 , Figure 10 shown, the main body 10 is provided with a guiding rib 15 and a supporting rib 16 in the dust collection chamber 11. The guiding rib 15 extends along the first direction, and the supporting rib 16 is located at one end of the guiding rib 15 away from the opening 12. The dust collection bag is fitted on the guiding rib 15 along the first direction, and when the dust collection bag is in the installation position, the dust collection bag abuts against the supporting rib 16.

[0076] Thus, the guiding ribs 15 and the supporting ribs 16 can guide the installation position of the dust collection bag in the dust collection chamber 11, improve the installation accuracy of the dust collection bag in the main body 10, and reduce the misinstallation of the dust collection bag. At the same time, when the dust collection bag is in the installation position, the supporting ribs 16 and the guiding ribs 15 can limit the position of the dust collection bag, so that the dust collection bag can be more stably and reliably connected to the installation position, further improving the reliability of the dust collection bag.

[0077] Preferably, when there are two opposite mounting ribs 14 on the inner wall of the dust collection chamber 11 and an installation groove 13 is formed between the two mounting ribs 14, the mounting rib 14 can be simultaneously formed as the guiding rib 15.

[0078] Furthermore, the dust collection bag includes a dust bag frame 31. When the dust collection bag is in the installation position, the dust bag frame 31 presses against the limiting member 40, and the dust bag frame 31 abuts against the guiding rib 15 and the supporting rib 16. It should be noted that the dust bag frame 31 is made of a rigid material.

[0079] Thus, the guiding rib 15 and the supporting rib 16 can provide a more stable supporting force for the dust bag frame 31, so that the dust collection bag can be more stably arranged at the installation position through the dust bag frame 31. And when the dust collection bag is in the installation position, the dust bag frame 31 can more stably press against the limiting member 40, so that the stopping end 421 is more stably located in the avoiding position, further improving the reliability and stability of the dust collection bag during use.

[0080] Preferably, as Figure 4 shown, the dust bag frame 31 is connected to the inner wall of the dust collection chamber 11.

[0081] In some embodiments, as Figure 9 shown, an air inlet 17 is provided on the inner wall of the dust collection chamber 11, and the dust collection bag is provided with a dust collection port. When the dust collection bag is in the installation position, the dust collection port is docked with the air inlet 17. The leak-proof dust collection assembly further includes: a sealing member, which is arranged between the main body 10 and the dust collection bag and simultaneously surrounds the air inlet 17 and the dust collection port. Thereby reducing or avoiding dust leakage at the dust collection port, reducing or avoiding dust flowing outside the dust collection bag, so as to ensure the dust collection effect of the dust collection bag.

[0082] As Figure 1 shown, the vacuum cleaner 100 according to the embodiment of the present invention includes the leak-proof dust collection assembly of the above embodiment.

[0083] The vacuum cleaner 100 of the present application, by adopting the vacuum cleaner 100 of the above embodiment, can remind whether the dust collection bag is correctly installed at the installation position by checking whether the closing of the opening 12 of the dust chamber cover 20 is blocked by the stop end 421, that is, whether the dust chamber cover 20 can completely cover the opening 12.
