Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a mite removal device. Background Technology

[0002] A mite removal device is a cleaning device used to remove mites and their excrement from household items such as mattresses, sofas, and carpets.

[0003] In related technologies, mite removal devices include a base, a roller brush, an air duct, and a dust cup. The base has a suction chamber inside and a suction port at the bottom. The roller brush is rolled inside the suction chamber, with part of the roller brush exposed at the suction port. When the roller brush rotates around its own axis, it can sequentially draw mites, mite excrement, and dust particles into the dust cup through the suction chamber and air duct.

[0004] However, among the related technologies, mite removal equipment suffers from technical problems such as large overall size, heavy weight, unstable center of gravity, and laborious operation. Utility Model Content

[0005] In view of the above problems, this application provides a mite removal device, which aims to reduce the overall size and weight of the device and lower the center of gravity, thereby avoiding the technical problem of laborious operation, improving the structural compactness of the mite removal device, and improving the user experience.

[0006] To achieve the above objectives, the embodiments of this application provide the following technical solutions:

[0007] This application provides a mite removal device, including: a base, a main body, an air duct, and a dust cup, wherein the main body is disposed on the base.

[0008] Along the extension direction perpendicular to the body, the body has a downward-opening receiving groove, the air duct is disposed in the receiving groove, the body also has a mounting position located below the air duct and opening downward, the dust cup is detachably installed in the mounting position, the side of the air duct facing the dust cup has an air outlet, the air outlet is directly connected to and communicates with the air inlet of the dust cup.

[0009] In the mite removal device provided in this application embodiment, by directly mounting the dust cup on the body, the structure between the dust cup and the body becomes more compact, thereby improving the structural compactness of the mite removal device and reducing the overall size and weight of the mite removal device. In addition, by mounting the dust cup at the bottom of the body, the center of gravity of the mite removal device is lowered, which improves the stability of the mite removal device during use and reduces the weight of the handheld device, making operation more effortless and thus improving the user experience.

[0010] In some embodiments, the dust cup is disposed near one end of the base.

[0011] This design further improves the structural compactness between the dust cup, body, and base, reducing the overall size and weight of the mite removal device. It also lowers the center of gravity of the mite removal device, improving its stability during use and reducing the weight of the handle, making operation easier and thus enhancing the user experience.

[0012] In some embodiments, the mite removal device further includes a dust cup unlocking mechanism. Along the extension direction of the body, the body has an accommodating cavity located below the mounting position. The dust cup unlocking mechanism is installed in the accommodating cavity and has a latch and a button. The dust cup has a locking groove that matches the latch. The bottom wall of the mounting position has a through hole through which the latch can pass.

[0013] The button is connected to the latch, and part of the button's structure is exposed outside the body. When a force is applied to the button, the button can at least drive the latch to move along the extension direction of the through hole toward the side away from the dust cup, so that the latch can be released from the locking groove.

[0014] This design allows the dust cup to be detachably connected to the main body via an unlocking mechanism, enabling the collected mites and excrement to be emptied for reuse.

[0015] In some embodiments, the housing includes a body and a rear cover, the rear cover and the body being detachably connected such that the rear cover and a portion of the body together enclose the receiving cavity.

[0016] This design makes it easy to remove the back cover of the unit from the main body to repair, maintain, and replace the dust cup unlocking mechanism in the housing cavity.

[0017] In some embodiments, the outer contour shape of the dust cup matches the outer contour shape of the body.

[0018] This design ensures that the dust cup and the main body are in surface contact, maximizing the connection area between them and increasing the connection strength between the dust cup and the main body. This, in turn, improves the stability of the mite removal equipment during operation and enhances the user experience.

[0019] In some embodiments, along the direction from the opening of the mounting position to the bottom wall, the side wall of the mounting position near the base is an inclined surface that slopes toward the base, so that the cross-sectional dimension at the opening of the mounting position is larger than the cross-sectional dimension at the bottom of the mounting position.

[0020] This design provides space for the dust cup to move during installation, making the installation process smoother.

[0021] In some embodiments, along the extension direction of the body, the top wall of the mounting position has a first limiting structure, and the top wall of the dust cup has a second limiting structure that matches the first limiting structure. When the dust cup is installed in the mounting position, the first limiting structure and the second limiting structure mutually limit and cooperate with each other.

[0022] This design, combined with the locking groove on the bottom wall of the dust cup and the locking buckle in the dust cup unlocking mechanism, ensures that the dust cup is fixed to the body in both the top and bottom directions. This further improves the structural stability between the dust cup and the body, thereby increasing the connection strength between the two, enhancing the stability of the mite removal equipment during operation, and improving the user experience.

[0023] In some embodiments, the first limiting structure is one of a limiting groove and a limiting protrusion, and the second limiting structure is the other of a limiting groove and a limiting protrusion.

[0024] This design is simple, easy to install, and easy to implement.

[0025] In some embodiments, the mite removal device further includes a sealing element surrounding the outer periphery of the air outlet to seal the gap between the air outlet and the dust cup.

[0026] This design prevents mites and their excrement from leaking between the air outlet and the dust cup, thereby improving the reliability of the mite removal equipment.

[0027] In some embodiments, the outer periphery of the air outlet has a sealing groove, and the sealing element is disposed within the sealing groove.

[0028] This design facilitates the securing of the seals, preventing them from slipping off the machine body after the dust cup is removed, thereby improving the sealing reliability between the air outlet and the dust cup.

[0029] In some embodiments, the mite removal device further includes a roller brush motor and a battery pack assembly. The base has a receiving cavity extending along a first direction. The roller brush motor and the battery pack assembly are located in the receiving cavity and are arranged side by side along the first direction. The first direction is consistent with the length direction of the base.

[0030] This configuration, by arranging the roller brush motor and battery pack assembly side-by-side along the first direction within the accommodating cavity, makes the layout of the roller brush motor and battery pack assembly within the mite removal device more rational, improving the structural compactness of the mite removal device and thus reducing the overall size and weight of the device. In addition, placing the roller brush motor and battery pack assembly at the base lowers the center of gravity of the mite removal device, improving its stability during use and reducing the weight to be held, making operation more effortless and thus enhancing the user experience.

[0031] In some embodiments, the mite removal device further includes a roller brush that is rotatably disposed on the base, and the receiving cavity is located on the rear side of the roller brush.

[0032] This configuration, with the roller brush motor and battery pack assembly placed in the receiving cavity and arranged side by side along the first direction, allows the roller brush, roller brush motor, and battery pack assembly to make reasonable use of the front, back, left, and right spaces of the receiving cavity within the base. This results in a more compact and rational structural layout of the roller brush, roller brush motor, and battery pack assembly within the base, thereby reducing the size of the base and the overall volume of the machine.

[0033] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the mite removal device provided by the embodiments of this application, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific implementation.

[0068] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, other embodiments obtained by those skilled in the art without creative effort are all within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0069] This application provides a mite removal device, such as... Figure 1 , Figure 2 and Figure 3 As shown, the mite removal device 10 includes a base 100 and a body 200, with the body 200 mounted on the base 100. The base 100 has a suction port 102 at its bottom. The length direction of the base 100 is perpendicular to the length direction of the body 200, with a first direction consistent with the length direction of the base 100 and a third direction consistent with the length direction of the body 200.

[0070] Furthermore, in conjunction with 4, Figure 5 and Figure 6 As shown, the mite removal device 10 also includes a roller brush 150, a roller brush motor 110, and a battery pack assembly 120, all of which are disposed within the base 100. The roller brush 150 is rotatably mounted within the base 100, the roller brush motor 110 drives the rotation of the roller brush 150, and the battery pack assembly 120 is configured to provide power to the roller brush motor 110. The battery pack assembly 120 allows the mite removal device 10 to be freed from the constraints of a charging cable, and the mite removal area is not limited by the location of the power source.

[0071] And such as Figure 4 and Figure 6 As shown, the base 100 has a receiving cavity 101 extending along a first direction. The receiving cavity 101 is located behind the roller brush 150. The roller brush motor 110 and the battery pack assembly 120 are located in the receiving cavity 101 and are arranged side by side along the first direction. In this way, the width dimension of the base 100 is reduced, the compactness of the structure in the base 100 is improved, thereby improving the overall structural compactness of the mite removal device 10, reducing the overall volume of the device, and making the center of gravity of the mite removal device 10 concentrated at the base 100. The center of gravity is lowered, which improves the stability of the mite removal device 10 during use and reduces the weight of the handheld device.

[0072] In addition, such as Figure 6 As shown, the base 100 also has a suction chamber 103 inside. The roller brush 150 is located inside the suction chamber 103 and is rolled against the wall of the suction chamber 103. Part of the roller brush 150 is exposed on the outside of the base 100 to directly contact the household items that need to be cleaned of mites and dust. Through rolling friction relative to the household items, the roller brush 150 removes mites and their excrement deeply embedded in the household items, assisting the mite removal device 10 in collecting mites and their excrement, and improving the reliability of the mite removal device 10. For example, both ends of the roller brush 150 are rotatably connected to the base 100. The rotatable connection methods include, but are not limited to, hole-shaft connection, pin connection, rolling bearing connection, etc.

[0073] Furthermore, such as Figure 6As shown, the receiving cavity 101 is located behind the roller brush 150, that is, the roller brush motor 110 and the battery pack assembly 120 are located behind the roller brush 150, and the suction port 102 on the base 100 is located between the roller brush 150 and the receiving cavity 101. This allows the roller brush 150, roller brush motor 110, and battery pack assembly 120 to make reasonable use of the front-to-back and left-to-right space of the receiving cavity 101 within the base 100, resulting in a more compact and rational structural layout of the roller brush 150, roller brush motor 110, and battery pack assembly 120 within the base 100. This, in turn, reduces the dimensions of the base 100 in the front-to-back, left-to-right, and up-down directions, thereby reducing the volume occupied by the mite removal device 10 in the space.

[0074] Combined Figure 7 and Figure 8 As shown, the mite removal device 10 also includes an air duct 300 and a dust cup 400. The air duct 300 is disposed in at least one of the base 100 and the main body 200, and its two ends are respectively connected to the suction port 102 and the dust cup 400. The dust cup 400 is disposed on the main body 200. In this way, when the user needs to remove mites and their excrement from mattresses, sofas, carpets and other home furnishings, the user can hold the main body 200 so that the base 100 is in direct contact with the mattresses, sofas, carpets and other home furnishings, so that the negative pressure at the suction port 102 can adsorb the mites and their excrement into the dust cup 400.

[0075] Furthermore, in combination Figure 8 , Figure 9 and Figure 10 As shown, along the extension direction of the vertical body 200, i.e., along the second direction, the body 200 has a downward-opening receiving groove 210, and the air duct 300 is disposed within the receiving groove 210. The body 200 also has a mounting position 220 located below the air duct 300 and opening downwards. The dust cup 400 is detachably mounted on the mounting position 220. The side of the air duct 300 facing the dust cup 400 has an air outlet 310 (e.g., ...). Figure 8 and Figure 10 As shown), the air outlet 310 and the air inlet 410 of the dust cup 400 (as shown) Figure 8 and Figure 9 As shown, directly connect and link. It should be noted that, as... Figure 7 and Figure 8 As shown, the direction perpendicular to the fuselage is defined as the second direction.

[0076] Furthermore, one end of the air outlet of the air duct 300 is connected to the suction chamber 103 that houses the roller brush 150. When the mite removal device 10 is needed to perform mite removal and dust removal operations, the mites and their excrement in household items such as mattresses, sofas, and carpets are stripped off under the rolling force of the roller brush 150, and under the negative pressure of the suction port 102, they enter the suction chamber 103 of the base 100, and then enter the dust cup 400 through the air duct 300 for centralized collection.

[0077] In this embodiment, by directly mounting the dust cup 400 onto the body 200, the structure between the dust cup 400 and the body 200 becomes more compact, thereby improving the structural compactness of the mite removal device 10 and reducing the overall size and weight of the mite removal device 10. In addition, by placing the dust cup 400 at the bottom of the body 200, the center of gravity of the mite removal device 10 is lowered, improving the stability of the mite removal device 10 during use and reducing the weight to be held, making operation more effortless and thus enhancing the user experience.

[0078] Specifically, Figure 7 and Figure 11 As shown, the dust cup 400 is positioned near the base 100, thereby further improving the structural compactness between the dust cup 400, the body 200, and the base 100, reducing the overall size and weight of the mite removal device 10; and further lowering the center of gravity of the mite removal device 10, improving the stability of the mite removal device 10 during use, and reducing the weight of the handheld device, making operation more effortless, thereby further enhancing the user experience.

[0079] Furthermore, such as Figure 8 and Figure 11 As shown, the outer contour shape of the dust cup 400 matches the outer contour shape of the body 200, so that the dust cup 400 and the body 200 are in surface contact, thereby maximizing the connection area between the two, improving the connection strength between the dust cup 400 and the body 200, and thus improving the stability of the mite removal device 10 during operation and enhancing the user experience.

[0080] In addition, such as Figure 8 and Figure 11 As shown, along the direction from the opening of the mounting position 220 to the bottom wall, the side wall of the mounting position 220 near the base 100 is an inclined surface that slopes towards the base 100, so that the cross-sectional dimension at the opening of the mounting position 220 is larger than the cross-sectional dimension at the bottom of the mounting position 220, so that the dust cup 400 can be installed at the mounting position 220 more quickly.

[0081] And such as Figure 8As shown, along the extension direction of the body 200, the top wall of the mounting position 220 has a first limiting structure 241, and the top wall of the dust cup 400 has a second limiting structure 430 that matches the first limiting structure 241. When the dust cup 400 is installed in the mounting position 220, the first limiting structure 241 and the second limiting structure 430 mutually limit and cooperate. Combined with the snap-fit ​​method between the locking groove 420 on the bottom wall of the dust cup 400 and the latch 510 in the dust cup unlocking mechanism 500, the dust cup 400 is fixed to the body 200 in both the upper and lower directions, thereby further improving the structural stability between the dust cup 400 and the body 200, and further improving the connection strength between the two, improving the stability of the mite removal device 10 during operation, and enhancing the user experience.

[0082] It should be noted that when the disassembled dust cup 400 needs to be installed onto the mounting position 220, the second limiting structure 430 on the top wall of the dust cup 400 needs to be connected with the first limiting structure 241 on the top wall of the mounting position 220, i.e., as follows: Figure 8 The connection between the middle body 200 and the dust cup 400 is then established. Then, with the connection point of the first limiting structure 241 and the second limiting structure 430 as the center of rotation, the bottom wall of the dust cup 400 rotates towards the mounting position 220, thereby mounting the dust cup 400 onto the mounting position 220. Its state is as follows: Figure 5 As shown.

[0083] For example, the first limiting structure 241 is one of a limiting groove and a limiting protrusion, and the second limiting structure 430 is the other of a limiting groove and a limiting protrusion, with the limiting groove and the limiting protrusion matching each other. The setting of the limiting protrusion and the limiting groove is simple in structure, convenient in installation, and easy to implement.

[0084] In this process, the side wall of the mounting position 220 near the base 100 is set as an inclined surface that slopes towards the base 100, so that the cross-sectional dimension of the opening of the mounting position 220 is larger than the cross-sectional dimension of the bottom of the mounting position 220, thereby providing room for the dust cup 400 to rotate during the installation process, making the installation process of the dust cup 400 onto the mounting position 220 smoother.

[0085] In addition, such as Figure 11 , Figure 12 , Figure 13 and Figure 14 As shown in any of the figures, the mite removal device 10 also includes a sealing element 600, which surrounds the outer periphery of the air outlet 310 to seal the gap between the air outlet 310 and the dust cup 400, thereby preventing mites and their excrement from leaking between the air outlet 310 and the dust cup 400, thus improving the mite removal reliability of the mite removal device 10.

[0086] Furthermore, such as Figure 10As shown, the outer periphery of the air outlet 310 has a sealing groove 320, and the sealing element 600 is disposed in the sealing groove 320 to facilitate the fixing of the sealing element 600 and prevent the sealing element 600 from slipping off the body 200 after the dust cup 400 is removed from the body 200, thereby improving the sealing reliability between the air outlet 310 and the dust cup 400.

[0087] In addition, such as Figure 7 , Figure 8 and Figure 9 As shown, the mite removal device 10 also includes a dust cup unlocking mechanism 500. Along the extension direction of the body 200, the body 200 has a receiving cavity 230 located below the mounting position 220. The dust cup 400 is installed in the mounting position 220, and the dust cup unlocking mechanism 500 is installed in the receiving cavity 230. This allows the mounting position 220 and the receiving cavity 101 to be arranged side by side along the length of the body 200, thereby reducing the radial dimension of the mite removal device 10 and thus reducing the overall size of the device.

[0088] In some specific embodiments, such as Figure 10 , Figure 11 and Figure 12 As shown, the housing 200 includes a main body 240 and a rear cover 250. The rear cover 250 and the main body 240 are detachably connected so that the rear cover 250 and part of the main body 240 together form a receiving cavity 230, facilitating the maintenance, repair, and replacement of the dust cup unlocking mechanism 500 within the receiving cavity 230. For example, Figure 12 and Figure 14 As shown, there is a positioning post 260 between the rear cover 250 and the body 240, and the dust cup unlocking mechanism 500 has a positioning hole (not shown in the figure) that matches the positioning post 260. The dust cup unlocking mechanism 500 is installed in the accommodating cavity 230 through the positioning post 260 and the positioning hole.

[0089] And such as Figure 15 and Figure 16 As shown, the dust cup unlocking mechanism 500 includes a latch 510 and a button 520. (As...) Figure 8 As shown, the dust cup 400 has a locking groove 420 that matches the latch 510, and the bottom wall of the mounting position 220 has a through hole 221 through which the latch 510 can pass, so that the latch 510 in the unlocking mechanism can extend or retract into the through hole 221 to engage or disengage with the locking groove 420 at the bottom of the dust cup 400. This design allows the dust cup 400 to be detachably connected to the body 200 via the dust cup unlocking mechanism 500, enabling the collected mites and excrement to be emptied for reuse. Furthermore, the engagement method between the latch 510 and the locking groove 420 is simple in structure and easy to implement.

[0090] The button 520 is connected to the latch 510, and part of the structure of the button 520 is exposed outside the body. When a force is applied to the button 520, the button 520 can at least drive the latch 510 to move away from the dust cup along the extension direction of the through hole 221, so that the latch 510 and the locking groove 420 are unlocked, thereby releasing the dust cup 400 from the body 200, making it easier to empty the dust mites and their excrement in the dust cup 400.

[0091] The mite removal device 10 provided in this application embodiment improves the structural compactness of the mite removal device 10 by arranging the dust cup 400 and the dust cup unlocking mechanism 500 side by side along the length of the body 200, thereby reducing the overall size and weight of the mite removal device 10. Furthermore, by placing the dust cup unlocking mechanism 500 below the dust cup 400, the dust cup unlocking mechanism 500 is positioned in the gap between the mounting position 220 and the base 100, further improving the structural compactness of the dust cup 400, the dust cup unlocking mechanism 500, and the base 100. At the same time, this lowers the center of gravity of the mite removal device 10, thereby improving the stability of the mite removal device 10 during use, reducing the weight of the handheld device, making operation more effortless, and enhancing the user experience.

[0092] Furthermore, such as Figure 15 and Figure 16 As shown, there is an angle between the movement direction of button 520 and the movement direction of latch 510; for example, the angle between them is 90°. Figure 17 and Figure 18 As shown, the button 520 has a driving part 521, and the latch 510 has a force-receiving part 511 that matches the driving part 521. When force is applied to the button 520, the driving part 521 applies a pushing force to the force-receiving part 511, causing the latch 510 to move away from the dust cup 400. This releases the latch 510 from the locking groove 420 at the bottom of the dust cup 400, allowing the dust cup 400 to be removed from the mounting position 220. The collected mites and excrement can then be emptied, facilitating the reuse of the dust cup 400. This arrangement ensures that the movement direction of the latch 510 and the button 520 are different, allowing them to move in a more convenient direction: the latch 510 moves along a third direction, while the button 520 moves along a first direction or radially along the body 200.

[0093] In some specific embodiments, such as Figure 17 and Figure 18As shown, the driving part 521 is a driving slope, forming an angle with the movement direction of the button 520. The force-receiving part 511 is a force-receiving slope that matches the driving slope, forming an angle with the movement direction of the latch 510. This allows the driving slope to directly contact the force-receiving slope and move along it when force is applied to the button 520, pushing the latch 510 away from the dust cup 400. This releases the latch 510 from the locking groove 420 at the bottom of the dust cup 400, facilitating the removal of the dust cup 400 from the mounting position 220 and the disposal of collected mites and excrement, enabling the dust cup 400 to be reused. The design of the driving slope and the force-receiving slope allows the button 520 and the latch 510 to move in different directions, and the structure is simple, reliable, and easy to implement.

[0094] like Figure 17 , Figure 18 and Figure 19 As shown, the dust cup unlocking mechanism 500 also includes a first housing 540 and a second housing 550. The first housing 540 and the second housing 550 are arranged opposite to each other and detachably connected to form a receiving space 541. Parts of the structure of the latch 510 and the button 520 are movably disposed in the receiving space 541 to protect and fix the connection structure between the latch 510 and the button 520, thereby improving the service life of the dust cup unlocking mechanism 500.

[0095] Furthermore, at least one of the first housing 540 and the second housing 550 has a first clearance notch 542 through which the latch 510 passes, so as to provide clearance space for the movement path of the latch 510. For example, the first housing 540 and the second housing 550 together form the first clearance notch 542.

[0096] Furthermore, such as Figure 17 and Figure 18 As shown, the button 520 includes a button body 522 and a keycap 523 connected in sequence. The keycap 523 is exposed outside the body 200 to facilitate the application of force to the keycap 523 to control the disassembly of the dust cup 400. Furthermore, at least one of the first housing 540 and the second housing 550 has a second clearance notch 543 through which the button body 522 can pass, providing clearance space for the movement path of the button 520. For example, the first housing 540 and the second housing 550 together form the second clearance notch 543.

[0097] For example, return Figure 11 , Figure 12 and Figure 13As shown, along the length of the base 100, i.e. along the first direction, the keycap 523 is located on the side of the body 200. On the one hand, this simplifies the front design and creates a clean appearance. On the other hand, the keycap 523 is located on the side, which makes it easier to press the button 520 while reducing the probability of accidental touch during the back-and-forth movement of the mite removal device 10.

[0098] Continue as Figure 16 , Figure 17 and Figure 18 As shown, the latch 510 also has a first limiting rib 514. When the latch 510 is locked with the lock groove 420, the first limiting rib 514 abuts against the inner wall surface of the side wall where the first clearance notch 542 is located, so as to limit the movement distance of the latch 510 toward the direction close to the dust cup 400, thereby controlling the movement of the latch 510 and preventing the latch 510 from over-extending.

[0099] The connection between the keycap 523 and the key body 522 has a second limiting rib 525. When the keycap 523 is in a free state, the second limiting rib 525 abuts against the inner wall surface of the side wall where the second clearance notch 543 is located, so as to limit the movement distance of the key 520 in the direction away from the latch 510, thereby controlling the movement of the key 520, avoiding the excessive extension of the key 520, and thus improving the aesthetics of the mite removal device 10.

[0100] In addition, such as Figure 16 , Figure 17 and Figure 18 As shown, the dust cup unlocking mechanism 500 also includes an elastic reset member 560. Along the movement direction of the latch 510, the first end of the elastic reset member 560 is connected to the end of the latch 510 away from the dust cup 400, and the second end of the elastic reset member 560 is connected to the cavity wall of the receiving space 541. The elastic reset member 560 is configured to drive the latch 510 towards the side closer to the dust cup 400 through its own elastic force. The elastic reset member 560 allows the latch 510 to extend out of the through hole 221 on the bottom wall of the mounting position 220 and engage with the locking groove 420 at the bottom of the dust cup 400, even without applying force to the button 520. Furthermore, under the elastic force of the elastic reset member 560, the latch 510 will not retract back into the receiving space without external force, thereby improving the reliability of the fixed connection between the dust cup 400 unlocking structure and the dust cup 400.

[0101] Furthermore, such as Figure 17 , Figure 18 and Figure 19As shown, the latch 510 has a first limiting portion 512 at one end facing the elastic reset member 560. The first end of the elastic reset member 560 cooperates with the first limiting portion 512 to limit and fix the first end of the elastic reset member 560. The cavity wall of the receiving space 541 corresponding to the elastic reset member 560 has a second limiting portion 544. The second limiting portion 544 cooperates with the second end of the elastic reset member 560 to limit and fix the second end of the elastic reset member 560. This arrangement fixes both ends of the elastic reset member 560 to the latch 510 and the cavity wall of the receiving space, respectively. This guides the elastic reset direction of the elastic reset member 560 while preventing it from sliding, thereby improving the reliability of the movement of the latch 510 relative to the locking groove 420 on the dust cup 400.

[0102] For example, the elastic reset member 560 is a reset spring.

[0103] In another example, the first limiting portion 512 is one of a first limiting groove and a first limiting protrusion; the second limiting portion 544 is one of a second limiting groove and a second limiting protrusion. Specifically, as shown... Figure 19 As shown, the first limiting part 512 is a first limiting protrusion, and the second limiting part 544 is a second limiting groove. The first end of the return spring is engaged with the first limiting protrusion, and the second end of the return spring is disposed in the second limiting groove and engaged with the second limiting groove. The limiting cooperation between the limiting groove and the limiting protrusion has a simple, reliable structure that is easy to implement.

[0104] In addition, combined Figure 17 , Figure 18 and Figure 19 As shown, the latch 510 has a first guide structure 513 extending along its direction of movement. At a position corresponding to the first guide structure 513 on the cavity wall of the accommodating space 541, a second guide structure 545 matching the first guide structure 513 is provided. The first guide structure 513 is configured to cooperate with the second guide structure 545. The arrangement of the first guide structure 513 and the second guide structure 545 limits the movement path of the latch 510, thereby improving the movement guidance of the latch 510 and thus improving the reliability of the engagement between the dust cup unlocking mechanism 500 and the dust cup 400.

[0105] like Figure 17 , Figure 18 and Figure 20As shown, the button body 522 has a third guide structure 524, and a fourth guide structure 546, matching the third guide structure 524, is located at a position on the cavity wall of the accommodating space 541 corresponding to the third guide structure 524. The third guide structure 524 is configured to cooperate with the fourth guide structure 546. The arrangement of the third guide structure 524 and the fourth guide structure 546 limits the movement path of the button 520, thereby improving the movement guidance of the button 520 and thus improving the reliability of the engagement between the dust cup unlocking mechanism 500 and the dust cup 400.

[0106] Furthermore, whether it is the setting of the first guide structure and the second guide structure 545, or the setting of the third guide structure 524 and the fourth guide structure 546, in conjunction with the setting of the driving slope and the force-bearing slope, when the force on the button 520 is transmitted to the latch 510, the movement direction of the latch 510 can be controlled, that is, it moves in a direction away from the dust cup 400.

[0107] For example, the first guide structure 513 is one of the first guide protrusion and the first guide groove, the second guide structure 545 is the other of the first guide protrusion and the first guide groove; the third guide structure 524 is one of the second guide protrusion and the second guide groove, and the fourth guide structure 546 is the other of the second guide protrusion and the second guide groove.
