[0071] Compared with the prior art, the present invention can at least achieve one of the following beneficial effects:

[0072] (1) An unlocking mechanism is provided on the side wall of the dust cup. By sliding the sliding sleeve by hand, the dust collection cup can be controlled to be removed and installed. Compared with holding the entire dust cup, it is easier to operate by holding the unlocking mechanism. Compared with applying force to the smooth side wall of the dust cup, sliding the sliding sleeve is more convenient and quicker, and the dust cup is not easily dropped from the hand. In short, the unlocking mechanism makes the disassembly of the dust collection cup more convenient and quicker, and the use experience is better;

[0073] (2) A dust scraping ring is provided at the rear end of the dust collection cup. When the dust collection cup is moved forward and removed, the dust scraping ring moves forward with the dust collection cup and scrapes the outer side wall of the filter component. On the one hand, it can clean the dust on the surface of the filter component and avoid the dust attached to the surface of the filter component from affecting the filtering effect of the filter component. On the other hand, while cleaning the dust collection cup, the dust attached to the surface of the filter component is also cleaned, killing two birds with one stone and improving the dust cleaning effect of the dust suction device;

[0074] (3) The sliding sleeve is a long strip-shaped U-shaped sleeve. When the hand holds the outside of the sliding sleeve, it can increase the contact area between the hand and the sliding sleeve during holding, so that the driving force exerted by the hand is dispersed to multiple positions of the hand, making it easier for the user to slide the sliding sleeve and making the operation of removing the dust collection cup simpler and easier;

[0075] (4) The bottom of the dust collection cup is provided with a guiding part. When the dust collection cup is assembled to the main body part of the vacuum cleaner, through the preliminary guiding of the dust scraping ring and then further guiding through the guiding part, the dust collection cup can be quickly and accurately assembled onto the main body part of the vacuum cleaner;

[0076] (5) Each component of the unlocking mechanism is exquisitely matched and compactly arranged. At the same time, it integrates a hook component for controlling the disassembly of the dust collection cup and a buckle component for controlling the opening and closing of the end cover. The user can control both by operating the unlocking mechanism with one hand, greatly improving the user experience of the vacuum cleaner.

[0077] In the present invention, the above technical solutions can also be combined with each other to achieve more preferred combination schemes. Other features and advantages of the present invention will be described in the subsequent description. Moreover, some advantages can be made obvious from the description or understood by implementing the present invention. The objectives and other advantages of the present invention can be realized and obtained from the content specifically pointed out in the description and the drawings. Description of the Drawings

It is understood that the devices are multifunctional and independent of their orientation in space.

[0112] The general working surface of the present invention can be a flat surface or a curved surface, which can be inclined or horizontal. For the convenience of description, the embodiments of the present invention are placed on a horizontal plane and used on the horizontal plane, and "high and low" and "up and down" are defined accordingly.

[0113] Embodiment 1

[0114] This embodiment provides a dust collection cup, as Figures 1 to 19 shown, including:

[0115] A dust cup 1, which is provided with a cavity for assembling a filter component of a dust suction device and storing part or all of the dust filtered out by the filter component;

[0116] An unlocking mechanism 2, which is located on the outer side wall of the dust cup 1 for detachably connecting the dust collection cup to the main body part of the dust suction device;

[0117] Among them, the unlocking mechanism 2 includes a sliding sleeve 21, a fixing frame 22, and a hook assembly 23. The fixing frame 22 is connected to the outer side wall of the dust cup 1. The sliding sleeve 21 is slidably connected to the fixing frame 22. The hook assembly 23 is located between the fixing frame 22 and the sliding sleeve 21. The hook assembly 23 is detachably connected to the main body of the dust suction device. By sliding the sliding sleeve 21, the connection or separation of the hook assembly 23 from the main body part of the dust suction device is controlled to achieve the detachable connection of the dust collection cup to the main body part of the dust suction device.

[0118] Compared with the prior art, in the dust collection cup of the present invention, an unlocking mechanism 2 is provided on the side wall of the dust cup 1. By sliding the sliding sleeve 21 with the hand, the dust collection cup can be removed and installed. Compared with holding the entire dust cup, it is easier to operate by holding the unlocking mechanism 2. Compared with applying force to the smooth side wall of the dust cup, sliding the sliding sleeve 21 is more convenient and faster, and the dust cup is not easily dropped from the hand. In short, the unlocking mechanism 2 makes the disassembly of the dust collection cup more convenient and faster, and the user experience is better.

[0119] It should be noted that since the sliding sleeve 21 can slide relative to the fixing frame 22, when the following mentions the positional relationship between other components and the sliding sleeve 21, it is defaulted to the position when the dust collection cup is installed on the dust suction device and the sliding sleeve does not slide, which is the original position of the sliding sleeve 21. If the positional relationship during the sliding of the sliding sleeve 21 is involved, it will be specifically described.

[0120] Preferably, the unlocking mechanism 2 is located at the bottom of the outer wall of the dust cup 1 for easy operation by the user. Specifically, the fixing frame 22 is located below the dust cup 1 and fixedly connected to the bottom of the outer wall of the dust cup 1, that is, the sliding sleeve 21 slides relative to the fixing frame 22 and the dust cup 1.

[0121] Preferably, the sliding direction A-A of the sliding sleeve 21 is parallel to the central axis B-B of the dust cup 1, that is, the sliding sleeve 21 slides back and forth relative to the fixing frame 22 and the dust cup 1 to facilitate the user to apply force more easily. It should be noted that the parallel here is not strictly parallel in the geometric sense, as long as it is roughly parallel, that is, even if A-A and B-B intersect, the included angle is not greater than 10°.

[0122] On both sides of the fixing frame 22, there are sliding grooves 221 for the sliding sleeve 21 to slide. The sliding grooves 221 are parallel to the central axis B-B of the dust cup 1. The sliding sleeve 21 is provided with sliding ribs 211 adapted to the sliding grooves 221. The sliding ribs 211 are embedded in the sliding grooves 221 and can slide in the sliding grooves 221, so that the sliding sleeve 21 can slide relative to the fixing frame 22, that is, the sliding sleeve 21 can slide relative to the dust cup 1.

[0123] The length of the sliding rib 211 is less than the length of the sliding groove 221 to make the sliding of the sliding sleeve 21 more stable.

[0124] The shape of the sliding sleeve 21 is similar to a "U" shape, with openings at the top and both ends, so that the sliding sleeve 21 can cover the outside of the fixing frame 22, and the two sliding ribs 211 are located at the tops of the inner side walls of the sliding sleeve 21 arranged oppositely.

[0125] In this embodiment, the sliding sleeve 21 is a long strip-shaped U-shaped sleeve. When the hand holds the outside of the sliding sleeve 21, it can increase the contact area between the hand and the sliding sleeve 21 when holding, and disperse the driving force applied by the hand to multiple positions of the hand, so that the user can slide the sliding sleeve 21 more easily and make the operation of removing the dust cup simpler and easier.

[0126] To increase the friction between the sliding sleeve 21 and the hand for the user to apply force and operate the sliding sleeve 21 better, one or more of anti-slip decorations such as anti-slip grooves, anti-slip strips, anti-slip points, and anti-slip patterns are provided on the outer wall of the sliding sleeve 21.

[0127] In this embodiment, a circular anti-slip groove 212 is provided at the front part of the outer side wall of the sliding sleeve 21; a strip-shaped anti-slip groove 213 is provided in the middle of the outer side wall of the sliding sleeve 21, and the strip-shaped anti-slip groove is perpendicular to A-A. Specifically, three parallel U-shaped strip-shaped anti-slip grooves are provided in the middle of the outer side wall of the sliding sleeve 21, and the U-shaped strip-shaped anti-slip grooves extend from one side of the outer side wall of the sliding sleeve 21 across the bottom end face of the sliding sleeve 21 to the other side of the outer side wall of the sliding sleeve 21. Among them, the circular anti-slip groove 212 is convenient for placing the thumb so that the thumb can apply force, and the strip-shaped anti-slip groove 213 increases the friction between the remaining four fingers and the sliding sleeve 21, which is convenient for the four fingers to hold and apply force.

[0128] The fixing frame 22 is provided with a hook assembling part 222 for assembling the hook component 23, and the hook assembling part 222 is located at the rear end of the bottom of the fixing frame 22.

[0129] The hook component 23 includes a hook element 231 and a first elastic member 232. The hook element 231 is rotatably connected to the fixing frame 22. The rear end of the hook element 231 is detachably connected to the main body part of the dust collection device. One end of the first elastic member 232 abuts against the fixing frame 22, and the other end of the first elastic member 232 abuts against the hook element 231.

[0130] A convex part 214 is provided inside the sliding sleeve 21. The convex part 214 abuts against the bottom of the hook element 231. When the sliding sleeve 21 slides forward, the convex part 214 is driven to move forward, thereby driving the hook element 231 to rotate counterclockwise, causing the rear end of the hook element 231 to rotate downward and separate from the main body part of the dust collection device, and at the same time compressing the first elastic member 232. Continuing to move the sliding sleeve 21 forward, the dust collection cup can be removed from the dust collection device.

[0131] Specifically, a tongue part 231a for detachably connecting with the main body part of the dust collection device is provided at the rear end of the hook element 231. A bayonet matching the tongue part 231a is provided on the main body part of the dust collection device. The tongue part 231a extends into the bayonet from bottom to top to realize the detachable connection between the dust collection cup and the dust collection device. When the tongue part 231a rotates downward, the tongue part 231a disengages from the bayonet.

[0132] First cylinders 231b are respectively provided at opposite positions on both sides of the hook element 231. The hook assembling part 222 is provided with first rotation holes 222a matching the first cylinders 231b. By inserting the first cylinders 231b into the first rotation holes 222a, the rotation connection between the hook element 231 and the hook assembling part 222 (i.e., the fixing frame 22) is realized.

[0133] A ribbed part 231c is provided at the front end of the hook element 231. A window 222b for the ribbed part 231c to pass through is opened at the bottom of the fixing frame 22, and the window 222b is located inside the hook assembling part 222.

[0134] The bottom end face of the hook element 231 slopes downward gradually from the rear end to the front end, so the front end of the bottom end face of the hook element 231 is lower than the rear end.

[0135] The hook element 231 is provided with an assembly groove opening upward and adapted to the shape of the hook element 231. A first fixing post 231d for fixing the first elastic member 232 is arranged in the assembly groove. The first fixing post 231d is located between the first cylinder 231b and the rib portion 231c. A second fixing post 222c corresponding to the first fixing post 231d is arranged at the bottom of the fixing frame 22 for fixing the first elastic member 232. The two ends of the first elastic member 232 are respectively abutted against the first fixing post 231d and the second fixing post 222c.

[0136] The second fixing post 222c is located between the window 222b and the first rotating hole 222a.

[0137] In this embodiment, the first elastic member 232 is a spring, and the two ends of the spring are respectively sleeved on the first fixing post 231d and the second fixing post 222c.

[0138] A convex portion 214 is arranged at the position of the sliding sleeve 21 corresponding to the hook element 231. Specifically, the convex portion 214 abuts against the bottom end face of the hook element 231 and is located directly below the two first cylinders 231b.

[0139] When the sliding sleeve 21 slides forward, it drives the convex portion 214 to move forward. The convex portion 214 drives the front end of the hook element 231 to rotate counterclockwise upward, so that the rib portion 231c penetrates into the window 222b. At the same time, the front end of the hook element 231 compresses the first elastic member 232, making the first elastic member 232 in a compressed state. The rear end of the hook element 231 rotates counterclockwise downward, so that the tongue portion 231a is separated from the bayonet. At the same time, continue to slide the sliding sleeve 21 forward to separate the entire dust collection cup from the main body of the vacuum cleaning device, realizing the removal of the dust collection cup from the vacuum cleaning device.

[0140] It should be noted that during the sliding process of the sliding sleeve 21, the convex portion 214 is always located below the hook element 231, that is, the convex portion 214 always abuts against the hook element 231 and does not disengage, so as to ensure that the dust collection cup can be smoothly reassembled into the vacuum cleaning device.

[0141] The dust collection cup further includes a limiting frame 3. The limiting frame 3 is connected to the outer side wall of the dust cup 1, abuts against the rear end of the fixing frame 22, and is located between the dust cup 1 and the sliding sleeve 21, that is, the sliding sleeve 21 covers the outside of the limiting frame 3.

[0142] Specifically, the limiting frame 3 abuts against the rear end of the sliding groove 221 to block the rear end opening of the sliding groove 221, thereby limiting the sliding range of the sliding sleeve 21.

[0143] The bottom end face of the limit frame 3 abuts against the sliding sleeve 21, and at the same time, the front end face of the limit frame 3 abuts against the convex portion 214. When the dust collection cup is placed on the vacuum cleaning device, the sliding sleeve 21 can only slide forward and cannot slide backward, further limiting the sliding sleeve 21.

[0144] The limit frame 3 is provided with a limit opening 31 for the hook element 231 to pass through, and the tongue portion 231a passes through the limit opening 31 and is detachably connected to the main body of the vacuum cleaning device. It should be noted that the size of the limit opening 31 does not affect the rotation of the hook element 231. In addition, the limit frame 3 abuts against the rear end of the hook assembly portion 222, playing a certain stabilizing role for the hook assembly 23.

[0145] It should be noted that the hook assembly portion 222 surrounds the front end and both sides of the hook element 231. The hook assembly portion 222 not only plays a role in assembling the hook assembly 23, but also plays roles of stabilizing, protecting, and limiting the hook element 231. In addition, the hook assembly portion 222 also plays a guiding role for the rib portion 231c to penetrate into the window 222b, so that when the rib portion 231c rotates counterclockwise with the hook element 231, it can quickly and accurately enter the window 222b upward.

[0146] The dust cup 1 includes a cup body 11 and an end cap 12. The front end of the cup body 11 is an open mouth, and the end cap 12 is detachably covered on the front open mouth of the cup body 11. An air inlet 101 is provided on the end cap 12.

[0147] The rear end of the cup body 11 is also an open mouth, so that when the dust collection cup is assembled to the vacuum cleaning device, the filter assembly is assembled into the cup body 11 from the rear open mouth of the cup body 11, and the filter assembly is communicated with the air inlet 101 and abuts against the end cap 12.

[0148] A dust scraping ring 13 is provided on the inner side wall at the rear end of the cup body 11. A dust scraping opening 131 is provided in the center of the dust scraping ring 13. The filter assembly passes through the dust scraping opening 131 and is assembled into the cup body 11. The dust scraping ring 13 surrounds the outside of the filter assembly and contacts the outer side wall of the filter assembly (the outer side wall of the filter mesh cover in this embodiment). When the dust collection cup is moved forward to remove it, while the dust scraping ring 13 moves forward with the dust collection cup, it scrapes forward along the outer side wall of the filter assembly, so that the dust attached to the outer side wall of the filter assembly falls into the cup body 11 or outside the cup body 11, so as to improve the filtering effect of the filter assembly when it is used next time.

[0149] It should be noted that the size of the dust scraping opening 131 is adapted to the size of the outer side wall of the filter assembly, so as to clean the dust attached to the outer side wall of the filter assembly.

[0150] In addition to cleaning the dust on the outer side wall of the filter assembly, the above-mentioned dust scraping ring 13 also plays a guiding role in the installation of the dust collection cup, so that the dust collection cup can be quickly and conveniently assembled to the vacuum cleaning device.

[0151] The end cover 12 includes a hinge portion 121 and a snap portion 122. The end cover 12 is hinged to the cup body 11 through the hinge portion 121, and the snap portion 122 is detachably snapped onto the cup body 11. For the convenience of operation, the hinge portion 121 and the snap portion 122 are oppositely arranged at the edge of the end cover 12.

[0152] To prevent dust in the cup body 11 from contaminating the end cover 12 when pouring out the dust, the hinge portion 121 is connected to the top of the cup body 11, and the snap portion 122 is snapped onto the bottom of the cup body 11. In this way, when the end cover 12 is opened, the end cover 12 is located above the bottom of the cup body 11, and the dust in the cup body 11 is not easily contaminated on the end cover 12 when being poured out.

[0153] The unlocking mechanism 2 is located at the bottom of the outer side wall of the cup body 11. Specifically, the fixing frame 22 and the limiting frame 3 are connected to the bottom of the outer side wall of the cup body 11.

[0154] In the present invention, the opening and closing of the end cover 12 are controlled by the unlocking mechanism 2. Therefore, the snap portion 122 is snapped onto the unlocking mechanism 2. Specifically, the unlocking mechanism 2 includes a releasing component 24, and the releasing component 24 is detachably connected to the snap portion 122.

[0155] The releasing component 24 includes a fastening element 241, a second elastic member 242, an unlocking element 243, and a third elastic member 244.

[0156] At the front end of the bottom of the fixing frame 22, there is a key assembly cavity 223 for the unlocking element 243 and the third elastic member 244. The key assembly cavity 223 is provided with a key opening 223a, and the opening direction of the key opening 223a is set forward. It should be noted that the key assembly cavity 223 is located in front of the hook assembly portion 222.

[0157] The fastening element 241 is located between the fixing frame 22 and the outer side wall of the cup body 11. The fastening element 241 is rotatably connected to the fixing frame 22. The front end of the fastening element 241 is detachably connected to the snap portion 122. The rear end of the fastening element 241 passes through the bottom of the fixing frame 22 and is located behind the key assembly cavity 223. The unlocking element 243 is installed in the key assembly cavity 223. The rear end of the unlocking element 243 passes through the rear cavity wall of the key assembly cavity 223 and abuts against the rear end of the fastening element 241. The two ends of the second elastic member 242 respectively abut against the outer side wall of the cup body 11 and the fastening element 241. The two ends of the third elastic member 244 respectively abut against the rear cavity wall of the key assembly cavity 223 and the unlocking element 243.

[0158] The unlocking element 243 is pressed backward to compress the third elastic member 244 to put it in a compressed state. The rear end of the unlocking element 243 moves backward, driving the end of the fastening element 241 to rotate upward clockwise, compressing the second elastic member 242 to put it in a compressed state. At the same time, the front end of the fastening element 241 rotates downward clockwise to separate from the buckle portion 122, and the end cover 12 pops up (a torsion spring is provided at the hinge between the end cover 12 and the cup body 11. Once the buckle portion 122 is separated from the fastening element 241, the end cover 12 immediately pops up under the action of the torsion spring).

[0159] Specifically, the buckling element 241 includes a buckling portion 241 a , a middle portion 241 b , and an abutment plate 241 c that are sequentially connected from front to back.

[0160] The buckling portion 241a is adapted to the buckle portion 122, that is, the buckling portion 241a is detachably connected to the buckle portion 122. Specifically, the buckling portion 241a is hooked together with the buckle portion 122 from bottom to top, and when the buckling portion 241a is rotated downward, the buckling portion 241a is separated from the buckle portion 122.

[0161] The middle portion 241b is rotatably connected to the fixing frame 22. Specifically, second cylinders 241d are respectively provided on both sides of the middle portion 241b, and the fixing frame 22 is provided with second rotating holes 224 that are compatible with the second cylinders 241d. The two second cylinders 241d are inserted into the corresponding second rotating holes 224 to realize the rotatable connection between the middle portion 241b and the fixing frame 22.

[0162] The upper end of the abutment plate 241c is connected to the rear end of the middle portion 241b, and the lower end of the abutment plate 241c passes through the bottom of the fixing frame 22 and is located behind the rear wall of the key assembly cavity 223, and the abutment plate 241c is tilted backward from the upper end to the lower end. A rectangular opening 225 is provided at the bottom of the fixing frame 22 for the abutment plate 241c to pass through, and the rectangular opening 225 is located behind the rear wall of the key assembly cavity 223.

[0163] The unlocking element 243 includes a key plate 243a, an upper end plate 243b and two side clamping plates 243c. The front end of the upper end plate 243b and the front end of the two side clamping plates 243c are connected to the rear end surface of the key plate 243a, preferably, vertically connected.

[0164] The front end surface of the key plate 243 a is exposed through the key opening 223 a so that the user can press the key plate 243 a through the key opening 223 a.

[0165] The rear end of the upper end plate 243b passes through the rear cavity wall of the key assembly cavity 223 and abuts against the abutting plate 241c. Specifically, the rear end face of the upper end plate 243b is an inclined surface, and its inclination angle is adapted to that of the abutting plate 241c, that is, the rear end face of the upper end plate 243b fits against the front end face of the abutting plate 241c to better drive the abutting plate 241c to rotate.

[0166] The rear ends of the two side clamping plates 243c pass through the rear cavity wall of the key assembly cavity 223, and tongues are provided at the rear ends of the two side clamping plates 243c. The tongues are located behind the rear cavity wall of the key assembly cavity 223 to prevent the unlocking element 243 from falling out of the key assembly cavity 223.

[0167] The two ends of the second elastic member 242 respectively abut against the outer side wall of the cup body 11 and the middle portion 241b. Specifically, the middle portion 241b is provided with a third fixing post 241e for fixing the second elastic member 242, and the third fixing post 241e is located behind the second cylinder 241d. A fourth fixing post is provided at a position corresponding to the third fixing post 241e on the bottom of the outer side wall of the cup body 11. In this embodiment, the second elastic member 242 is a spring, and the two ends of the second elastic member 242 are respectively sleeved on the third fixing post 241e and the fourth fixing post.

[0168] The two ends of the third elastic member 244 respectively abut against the rear cavity wall of the key assembly cavity 223 and the key plate 243a, and the upper end plate 243b and the two side clamping plates 243c surround the outside of the third elastic member 244.

In this embodiment, the third elastic member 244 is a spring, and the two ends of the third elastic member 244 are respectively sleeved on the fifth fixing post 223b and the sixth fixing post.

[0169] In addition, a first through port 223c for the upper end plate 243b to pass through is formed on the rear cavity wall of the key assembly cavity 223, and a second through port 223d for the side clamping plate 243c to pass through is further formed on the rear cavity wall of the key assembly cavity 223. It should be noted that the size of the tongue at the rear end of the side clamping plate 243c is larger than the size of the second through port 223d to ensure that the unlocking element 243 will not fall off from the key assembly cavity 223.

[0170] To facilitate the user's pressing, the front end face of the key plate 243a is provided with one or several of anti-slip decorations such as anti-slip patterns, anti-slip grooves, anti-slip points, and anti-slip strips.

[0171] When it is necessary to open the end cover 12 of the dust collection cup, press the button plate 243a backward to compress the third elastic member 244 to make it in a compressed state. The upper end plate 243b moves backward with the button plate 243a, driving the abutting plate 241c to rotate clockwise upward, compressing the second elastic member 242 to make it in a compressed state. At the same time, the fastening portion 241a rotates clockwise downward, and the fastening portion 241a is separated from the fastening portion 122. The end cover 12 pops up upward under the action of the torsion spring, and the end cover 12 is opened.

[0172] It should be noted that the button assembly cavity 223 is located in front of the sliding groove 221, blocking and limiting the front opening of the sliding groove 221. When the unlocking assembly 24 is not provided in some embodiments, the fixing frame 22 can be provided with other types of blocks in front of the sliding groove 221 to limit the sliding of the sliding sleeve 21.

[0173] A guiding portion 14 is further provided at the bottom of the outer side wall of the cup body 11. The guiding portion 14 is located behind the fixing frame 22 so that the dust collection cup can be quickly and accurately assembled into the vacuum cleaning device.

[0174] In some embodiments, the unlocking mechanism 2 includes the hook assembly 23 but does not include the unlocking assembly 24. The unlocking mechanism 2 can only control the installation of the dust collection cup to the vacuum cleaning device and the removal of the dust collection cup from the vacuum cleaning device, and cannot control whether the end cover of the dust collection cup is opened or not.

[0175] In some embodiments, the unlocking mechanism 2 includes both the hook assembly 23 and the unlocking assembly 24. The unlocking mechanism 2 can both control the installation of the dust cup to the vacuum cleaning device and the removal of the dust cup from the vacuum cleaning device, and can also control whether the end cover of the dust collection cup is opened or not. The unlocking mechanism 2 is provided with both the hook assembly 23 and the unlocking assembly 24, and is further divided into the following two cases:

[0176] (1) As shown in Figure 5 and Figure 6 , at this time, the end cover can be opened first and then the dust collection cup can be removed, or the dust collection cup can be removed first and then the end cover can be opened, that is, there is no order requirement for removing the dust collection cup and opening the end cover, and it can be done casually.

[0177] (2) As shown in Figure 7 and Figure 8As shown, only by opening the end cap first can the dust collection cup be removed at this time. Specifically, the unlocking mechanism 2 further includes a shielding component 25 at this time. The shielding component 25 is located between the outer side wall of the cup body 11 and the fixing frame 22. When the end cap 12 is closed, the shielding component 25 shields the window 222b, preventing the hook element 231 from rotating, so that the tongue portion 231a is always located within the bayonet. The sliding sleeve 21 is blocked by the hook element 231 and cannot slide, and the dust collection cup cannot be removed. When the end cap 12 is opened, the shielding component 25 no longer shields the window 222b. By sliding the sliding sleeve 21 forward, the hook element 231 can be rotated counterclockwise, causing the tongue portion 231a to disengage from the bayonet. Continuing to move the dust collection cup forward can remove it from the vacuum cleaning device.

[0178] The above-mentioned shielding component 25 includes a fourth elastic member 251 and a blocking element 252.

[0179] The blocking element 252 includes an abutting portion 252a, a moving plate 252b, and a baffle portion 252c that are connected in sequence from front to back.

[0180] The abutting portion 252a is located between the outer side wall of the cup body 11 and the fastening element 241. The abutting portion 252a is provided with a long slot 252d for the second elastic member 242 to pass through. The upper end surface of the abutting portion 252a contacts the outer side wall of the cup body 11, and there is a gap between the lower end surface of the abutting portion 252a and the fastening element 241. On the one hand, it prevents the abutting portion 252a from affecting the rotation of the fastening element 241 and the expansion and contraction of the second elastic member 242. On the other hand, it prevents the second elastic member 242 from affecting the forward and backward movement of the blocking element 252.

[0181] The fixing frame 22 is provided with a moving slot 226 for the moving plate 252b to move. The moving slot 226 is located between the window 222b and the rectangular opening 225. The front and rear slot walls of the moving slot 226 are used to limit the moving length S of the moving plate 252b. S is the distance from the front slot wall to the rear slot wall of the moving slot 226. In this embodiment, the front slot wall of the moving slot 226 is perpendicular to the bottom of the moving slot 226.

[0182] It should be noted that the length of the long slot 252d is not less than S to ensure smooth movement of the blocking element 252.

[0183] The upper and lower ends of the moving plate 252b are respectively in contact with the bottom of the outer side wall of the cup body 11 and the bottom of the moving slot 226. The rear end surface of the moving plate 252b is provided with a seventh fixing post 252e for fixing the fourth elastic member 251.

[0184] The bottom of the outer side wall of the cup body 11 is provided with a protruding abutting groove 15. The mouth of the abutting groove 15 faces forward, and an eighth fixing post corresponding to the seventh fixing post 252e is provided in the abutting groove 15.

[0185] The two ends of the fourth elastic member 251 are respectively in contact with the moving plate 252b and the abutting groove 15. In this embodiment, the fourth elastic member 251 is a spring, and the two ends of the fourth elastic member 251 are respectively sleeved on the seventh fixing post 252e and the eighth fixing post.

[0186] The bottom end face of the baffle portion 252c is in contact with the fixing frame 22, and the length of the baffle portion 252c is greater than the distance from the rear groove wall of the moving groove 226 to the rear opening wall of the window 222b, and the length of the baffle portion 252c is less than the distance from the front groove wall of the moving groove 226 to the front opening wall of the window 222b.

[0187] The top end face of the baffle portion 252c is in contact with the outer side wall of the cup body 11, so as to ensure that when the baffle portion 252c covers the window 222b, the rib portion 231c cannot lift the baffle portion 252c.

[0188] When the end cover 12 is in the closed state, the front end of the abutting portion 252a is in contact with the buckle portion 122, the rear end face of the moving plate 252b is in contact with the rear groove wall of the moving groove 226, the fourth elastic member 251 is in a compressed state, the baffle portion 252c covers the window 222b, and the rib portion 231c is in contact with the baffle portion 252c. At this time, the rib portion 231c cannot pass through the window 222b and rotate upward, resulting in that the entire hook element 231 cannot rotate, and the sliding sleeve 21 cannot slide, so the dust collection cup cannot be removed from the vacuum cleaning device.

[0189] When the end cover 12 is opened, the blocking element 252 moves forward as a whole under the elastic force of the fourth elastic member 251. At this time, the moving plate 252b is in contact with the front groove wall of the moving groove 226, the baffle portion 252c moves forward to expose the entire window 222b. If the sliding sleeve 21 is slid forward at this time, driving the protruding portion 214 to move forward, the protruding portion 214 drives the front end of the hook element 231 to rotate counterclockwise upward, the rib portion 231c passes through the window 222b, and the tongue portion 231a rotates counterclockwise downward and disengages from the bayonet. Continuing to slide the sliding sleeve 21 forward, the dust collection cup moves forward as a whole, and the dust collection cup is removed from the vacuum cleaning device.
