Description

Technical Field

[0001] The present application relates to the technical field of cleaning tools, and in particular to a dust cup structure, a handheld device and a cleaning device. Background Art

[0002] With the development of science and technology and the improvement of living standards, living conditions are constantly improving, and people have higher requirements for the quality of their living environment. Household dust removal equipment such as cleaning equipment (such as vacuum cleaners, floor scrubbers, etc.) are increasingly appearing in people's lives.

[0003] In related technologies, the cleaning equipment may include a base station and a handheld device, which is detachably connected to the base station. The handheld device includes a handheld body and a dust cup arranged on the handheld body. The dust cup has an openable and closable end cover. When the handheld device is working, it can suck impurities on the surface to be cleaned into the dust cup. The base station can automatically collect dust, open the end cover and clean the impurities in the dust cup each time it is connected to the handheld device.

[0004] However, in some application scenarios, when the user uses the handheld device alone and needs to manually empty the dust, it is inconvenient to open the end cover of the dust cup, and manual emptying of the dust and automatic dust collection cannot be taken into account at the same time. Utility Model Content

[0005] The embodiments of the present application provide a dust cup structure, a handheld device and a cleaning device to solve the problems in the related art that when a user uses a handheld device alone and needs to manually empty the dust, the operation is inconvenient and manual dust emptying and automatic dust collection cannot be taken into account at the same time.

[0006] In a first aspect, the present application provides a dust cup structure, which includes:

[0007] A dust cup body, wherein the dust cup body has a dust collecting cavity, and the dust collecting cavity has a first dust removal port;

[0008] End cap structure, the end cap structure includes a primary end cap assembly, a secondary end cap assembly and a clamping assembly;

[0009] The first-stage end cover assembly is arranged at the first dust removal port and is rotatably connected to the dust cup body to flip open or close the first dust removal port;

[0010] The clamping assembly is connected to the dust cup body, and at least a portion of the clamping assembly is movably buckled on the first-stage end cover assembly to lock or unlock the first-stage end cover assembly;

[0011] The first-stage end cover assembly is provided with a second dust removal port, which is communicated with the dust collecting chamber. The second-stage end cover assembly is arranged at the second dust removal port and is rotatably connected to the first-stage end cover assembly to flip open or close the second dust removal port.

[0012] The secondary end cover assembly is configured to open the second dust removal port under the suction force of the base station when the handheld device is connected to the base station.

[0013] The dust cup structure provided by the present application is provided with an end cap structure, which includes a primary end cap assembly, a secondary end cap assembly and a snap-on assembly. The primary end cap assembly can be flipped to close or open the first dust removal port when the snap-on assembly is locked or unlocked. At this time, the user only needs to operate the snap-on assembly to open the first dust removal port to dump dust when the dust cup structure is used alone, which has the effect of convenient dust dumping operation; the primary end cap assembly has a second dust removal port, which is connected to the dust collecting chamber, and the secondary end cap assembly is provided at the second dust removal port and is rotatably connected to the primary end cap assembly to flip open or close the second dust removal port. The secondary end cap assembly is used to be configured to open the second dust removal port under the suction force of the base station when the handheld device is connected to the base station. The above structural setting method can facilitate the dust dumping operation of the handheld device in both cases of being used alone and in conjunction with the base station, so as to solve the problem in the background technology that when the user uses the handheld device alone and needs to manually dump dust, the operation is inconvenient, and manual dust dumping and automatic dust collection cannot be taken into account at the same time.

[0014] As an optional embodiment, the first-stage end cover assembly includes a bottom cover; the bottom cover has a first connecting portion, the dust cup body has a second connecting portion, and the first connecting portion is rotatably connected to the second connecting portion;

[0015] A second dust removal port is provided on the bottom cover, and the secondary end cover assembly is used to flip toward the side away from the dust cup body to open the second dust removal port.

[0016] With this arrangement, on the one hand, a second dust removal port is opened on the bottom cover to simplify the structure; on the other hand, the secondary end cover assembly is used to flip toward the side away from the dust cup body to open the second dust removal port, which has the effect of not interfering with the interior of the dust cup body and is conducive to the discharge of impurities in the dust cup body.

[0017] As an optional embodiment, the secondary end cover assembly includes a rotating cover, a fixed shaft and a metal part;

[0018] The rotating cover is provided with a hinge hole, the bottom cover is provided with a fixing groove, the fixing shaft passes through the hinge hole and is movably inserted into the fixing groove;

[0019] The rotating cover is also provided with a magnetic attraction portion, a card slot is opened in the magnetic attraction portion, the metal part is arranged in the card slot, and a magnet is provided on the bottom cover, and the magnet is used to absorb the metal part.

[0020] In this way, the rotational connection method between the rotating cover and the bottom cover is simplified by providing a fixed shaft through a hinge hole and inserting it into the fixed groove. In addition, a magnetic part is provided on the rotating cover, and a metal part is provided in the magnetic part. The magnet on the bottom cover is adsorbed with the metal part to make the rotating cover adsorbed on the bottom cover, thereby achieving the effect of adsorbing and closing the second dust removal port, further simplifying the structure and facilitating operation.

[0021] As an optional embodiment, a torsion spring is further included. The torsion spring is sleeved on the fixed shaft, and part of the torsion spring is in contact with the rotating cover. The torsion spring is configured to apply a force to the rotating cover to flip it toward the bottom cover.

[0022] With this arrangement, the torsion spring applies force to the rotating cover to flip it toward the bottom cover. As can be understood, while the rotating cover and the bottom cover are closed by suction, the force of the torsion spring can also achieve a tight closure, improving the closure stability of the second dust removal port. Furthermore, after the handheld device is connected to the base station for automatic dust collection, the rotating cover can automatically flip and close under the force of the torsion spring, further simplifying the operation steps and improving reliability.

[0023] As an optional embodiment, the hinge hole and the magnetic part are respectively located on both sides of the rotating cover along the first direction, the length direction of the fixed axis is parallel to the second direction, and the first direction is perpendicular to the second direction.

[0024] This arrangement places the hinge hole and magnetic portion on either side of the rotating cover along the first direction, allowing force to be applied to both ends of the rotating cover along the first direction, further tightening the cover and improving its sealing performance. By arranging the length of the fixed shaft parallel to the second direction, and the first and second directions perpendicular, the axis of the fixed shaft can be used as the rotation center of the rotating cover, improving transmission efficiency.

[0025] As an optional embodiment, the secondary end cover assembly further includes a first sealing member, a boss is provided on the circumferential edge of the rotating cover, and the first sealing member is sleeved on the boss to seal the second dust removal port.

[0026] In this way, by setting the first sealing member to be sleeved on the boss, the sealing structure is simplified, the sealing effect between the rotating cover and the bottom cover is improved, and the impurities collected in the dust cup body are effectively prevented from leaking through the gap between the rotating cover and the bottom cover.

[0027] As an optional embodiment, the first-stage end cover assembly also includes a second seal, the bottom cover is provided with a sealing groove along the circumference, the second seal is arranged in the sealing groove, and part of the second seal is located outside the sealing groove to seal the first dust removal port.

[0028] In this way, by setting the second seal in the sealing groove and partially arranging the second seal outside the sealing groove, the sealing structure between the bottom cover and the dust cup body can be simplified, effectively preventing impurities inside the dust cup body from leaking through the gap between the dust cup body and the bottom cover when the dust cup body is working.

[0029] As an optional embodiment, the clamping assembly includes a clamping block and an elastic member;

[0030] A mounting groove is provided on the side wall of the dust cup body, and the clamping block is rotatably connected in the mounting groove. The clamping block has a clamping joint, and the clamping joint protrudes from the mounting groove;

[0031] The bottom cover is provided with a clamping groove; the elastic member is arranged between the clamping joint and the inner wall of the installation groove, and is configured to apply elastic force to the end of the clamping block away from the clamping joint, so that the clamping joint is clamped in the clamping groove.

[0032] With this arrangement, the snap block is rotatably connected in the installation slot, and the elastic member applies a force to the end of the snap block away from the snap connector, so that the snap connector always has a tendency to rotate toward the snap slot, so that the snap connector is stably clamped in the snap slot, thereby improving the connection stability. When the user needs to contact the lock of the bottom cover, he only needs to press the end of the snap block away from the snap connector to overcome the elastic force of the elastic member and disengage the snap connector from the snap slot. This structure is simple, convenient for user operation, and helps to improve the user experience.

[0033] In a second aspect, the present application provides a handheld device, which includes a handheld body and the above-mentioned dust cup structure, and the dust cup structure is movably connected to the handheld body.

[0034] With such arrangement, the handheld device has the beneficial technical effect of the above-mentioned dust cup structure, namely, it can facilitate the dust emptying operation of the handheld device when used alone or in conjunction with the base station.

[0035] In a third aspect, the present application provides a cleaning device, which includes a base station and the above-mentioned handheld device, and the base station is movably connected to the handheld device.

[0036] With such a configuration, the cleaning device has all the beneficial technical effects of the above-mentioned handheld device and dust cup structure, and facilitates the user's dust emptying operation in various usage scenarios, thereby enhancing the user's usage experience.

[0056] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0057] First, those skilled in the art should understand that these embodiments are merely used to explain the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art may adjust them as needed to suit specific applications.

[0058] Secondly, it should be noted that in the description of this application, terms such as "up", "down", "left", "right", "front", "back", "inside", and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on this application.

[0059] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0060] Throughout this specification, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present disclosure. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0061] With the development of science and technology and the improvement of living standards, living conditions are constantly improving, and people have higher requirements for the quality of their living environment. Household dust removal equipment such as cleaning equipment (such as vacuum cleaners, floor scrubbers, etc.) are increasingly appearing in people's lives.

[0062] Cleaning equipment such as vacuum cleaners and mops usually include a base station and a handheld device. The handheld device is detachably connected to the base station. The handheld device includes a handheld body and a dust cup arranged on the handheld body. The dust cup has an openable and closable end cover. The handheld device is separated from the base station when working. The user can operate the handheld device to suck impurities on the surface to be cleaned into the dust cup. The base station can automatically collect dust, open the end cover and clean impurities in the dust cup each time it is connected to the handheld device.

[0063] However, in some application scenarios, for example, when there are a lot of impurities on the surface to be cleaned, or when the impurities collected in the base station are full, or when it is inconvenient for the user to place the handheld device in the base station, and the user continues to clean the surface to be cleaned and needs to empty the dust, the handheld device will be used alone to empty the dust. At this time, the user needs to manually open the end cover. In the related art, since the handheld device can automatically collect dust when used in conjunction with the base station, the connection structure on its end cover for controlling the opening is complex.

[0064] For example, in related technologies, a boss is provided at the dust cup lock, which automatically opens when the dust cup is placed in the base station. However, the dust cup bottom cover cannot be reset when the dust cup is removed from the base station, requiring the user to manually close the dust cup bottom cover, which is inconvenient. Alternatively, a motion structure can be provided at the base station to reset the dust cup bottom cover, but this solution is relatively costly.

[0065] In other settings, the automatic dust collection of the base station can be met by setting a torsion spring and magnetic suction. The end cover is opened by the suction of the motor and automatically closed after being taken out. However, it is not easy to empty the dust alone, and magnetic suction is not very reliable. When there are a lot of heavy objects in the dust cup, it is easy to open by impact.

[0066] The above-mentioned related technologies make it inconvenient to manually open the end cover of the dust cup. If the operation is improper, it may even cause impurities in the dust cup to scatter, reducing the user experience.

[0067] In view of the above problems, the present application provides a dust cup structure, a handheld device and a cleaning device, the dust cup structure including: a dust cup main body, a dust collecting chamber in the dust cup main body, and a first dust removal port; an end cover structure, the end cover structure including a first-level end cover assembly, a second-level end cover assembly and a snap-on assembly; the first-level end cover assembly is arranged at the first dust removal port and is rotatably connected to the dust cup main body to flip open or close the first dust removal port; the snap-on assembly is connected to the dust cup main body, and the snap-on assembly is at least partially movably buckled on the first-level end cover assembly to lock or unlock the first-level end cover assembly; the first-level end cover assembly has a second dust removal port, the second dust removal port is connected to the dust collecting chamber, the second-level end cover assembly is arranged at the second dust removal port, and is rotatably connected to the first-level end cover assembly to flip open or close the second dust removal port; the second-level end cover assembly is configured to open the second dust removal port under the action of the suction force of the base station when the handheld device is connected to the base station.

[0068] The user only needs to operate the snap-on assembly to open the first dust removal port to empty the dust when using the handheld device alone, which has the effect of facilitating the operation of emptying the dust; by setting a second dust removal port on the first-level end cover assembly, the second dust removal port is connected to the dust collecting chamber, and the second-level end cover assembly is set at the second dust removal port and is rotatably connected to the first-level end cover assembly to flip open or close the second dust removal port. The setting method of the above structure can facilitate the dust emptying operation of the handheld device when it is used alone or in conjunction with the base station, so as to solve the problem in the background technology that when the user uses the handheld device alone and needs to empty the dust manually, the operation is inconvenient, and manual dust emptying and automatic dust collection cannot be taken into account at the same time.

[0069] like Figures 1 to 3 As shown, an embodiment of the present application provides a dust cup structure 10, which includes:

[0070] The dust cup body 100 has a dust collecting chamber 101 therein, and the dust collecting chamber 101 has a first dust removal port 102. The dust cup body 100 can be cylindrical to hold more impurities.

[0071] The end cover structure 200 includes a primary end cover assembly 210 , a secondary end cover assembly 220 and a clamping assembly 230 .

[0072] The first-stage end cap assembly 210 is disposed at the first dust removal port 102 and is rotatably connected to the dust cup body 100 to flip open or close the first dust removal port 102. Of course, in some examples, the first-stage end cap assembly 210 is horizontally rotatably connected to the dust cup body 100, and the first-stage end cap assembly 210 can be horizontally rotated to open or close the first dust removal port 102.

[0073] The snap-fit ​​assembly 230 is connected to the dust cup body 100, and the snap-fit ​​assembly 230 is at least partially movably buckled on the primary end cap assembly 210 to lock or unlock the primary end cap assembly 210. In some examples, the snap-fit ​​assembly 230 is at least partially movably buckled on the primary end cap assembly 210 so that part of the structure of the primary end cap assembly 210 is confined between the dust cup body 100 and part of the structure of the snap-fit ​​assembly 230, thereby locking the primary end cap assembly 210 and preventing the primary end cap assembly 210 from flipping over. When part of the structure of the snap-fit ​​assembly 230 is out of contact with the primary end cap assembly 210, the lock on the primary end cap assembly 210 can be released, and the primary end cap assembly 210 can flip over. It can be understood that the locking or unlocking of the primary end cap assembly 210 by the snap-fit ​​assembly 230 can achieve the closing or opening of the first dust removal port 102.

[0074] The primary end cap assembly 210 has a second dust removal port 2101, which is in communication with the dust collection chamber 101. The secondary end cap assembly 220 is disposed at the second dust removal port 2101 and is rotatably connected to the primary end cap assembly 210 to flip open or close the second dust removal port 2101. Of course, in some examples, the rotational connection between the secondary end cap assembly 220 and the primary end cap assembly 210 can be a horizontal rotational connection, and the secondary end cap assembly 220 rotates horizontally to open or close the second dust removal port 2101. The secondary end cap assembly 220 is configured to open the second dust removal port 2101 under the suction force of the base station when the handheld device is connected to the base station. It should be noted that in the relevant technical field, the base station has components such as a motor that provides suction force. The motor sucks and flips the secondary end cover assembly 220 through the corresponding pipe to open the second dust removal port 2101, and sucks out the impurities in the dust collecting chamber 101 of the dust cup body 100. The embodiment of this application does not limit the specific structure of the base station.

[0075] Through the above setting method, when the user uses the handheld device alone and needs to empty the dust, he only needs to operate the snap-on assembly 230, and the connection between the first-level end cover assembly 210 and the dust cup body 100 can be released in one operation. At this time, the first dust removal port 102 is opened, and the impurities in the dust collection chamber 101 can be poured out through the first dust removal port 102. The structure is simple and the operation is convenient. The handheld device is connected to the base station, and the base station sucks and flips the second-level end cover assembly 220 through the corresponding pipeline to open the second dust removal port 2101, and sucks out the impurities in the dust collection chamber 101 of the dust cup body 100. This process can be automatically realized, thereby achieving the effect of automatic dust collection. Compared with the related art, the opening process of the second dust removal port 2101 does not require the operation of the snap-on assembly 230 and other connecting structures. It can be opened only by the suction force provided by the base station, further simplifying the structure, improving convenience, and taking into account the functions of manual dust emptying and automatic dust collection.

[0076] Please continue to refer to Figures 1 to 3 The first-level end cover assembly 210 includes a bottom cover 211 .

[0077] The bottom cover 211 has a first connecting portion 212 , and the dust cup body 100 has a second connecting portion 103 . The first connecting portion 212 is rotatably connected to the second connecting portion 103 .

[0078] A second dust removal port 2101 is provided on the bottom cover 211 , and the secondary end cover assembly 220 is used to flip toward the side away from the dust cup body 100 to open the second dust removal port 2101 .

[0079] The bottom cover 211 is provided with a second dust removal port 2101, simplifying the structure. The opening and closing of the second dust removal port 2101 does not affect the opening and closing of the bottom cover 211, thus achieving a non-interference effect. The secondary end cap assembly 220 is used to flip toward the side away from the dust cup body 100 to open the second dust removal port 2101, without causing interference with the interior of the dust cup body 100, thereby facilitating the discharge of impurities within the dust cup body 100.

[0080] It should be noted that one of the first connecting portion 212 and the second connecting portion 103 is a hinge shaft, and the other is a hinge support. The hinge shaft is rotatably connected to the hinge support to rotatably connect the dust cup body 100 and the bottom cover 211. Its structure is simple, easy to manufacture, and helps to reduce costs.

[0081] Reference Figures 4 to 9 As shown, combined with Figures 1 to 3 The secondary end cover assembly 220 includes a rotating cover 221, a fixed shaft 222, and a metal member 223. The rotating cover 221 has a hinge hole 2211, and the bottom cover 211 has a fixed slot 2111. The fixed shaft 222 passes through the hinge hole 2211 and is movably inserted into the fixed slot 2111, so that the rotating cover 221 is rotatably connected to the bottom cover 211.

[0082] The rotating cover 221 is also provided with a magnetic attraction portion 224, which defines a slot within which the metal member 223 is positioned. The bottom cover 211 is provided with a magnet 2112 for attracting the metal member 223. In a specific implementation, at least one positioning pin can be provided within the slot, and a corresponding positioning pin hole can be provided on the metal member 223. When installing the metal member 223 into the slot, the positioning pin hole and the positioning pin can cooperate to quickly locate and install the metal member 223.

[0083] By providing a fixed shaft 222 that passes through a hinge hole 2211 and is inserted into the fixed groove 2111, the rotational connection between the rotating cover 221 and the bottom cover 211 is simplified. In addition, by providing a magnetic portion 224 on the rotating cover 221 and arranging a metal member 223 within the magnetic portion 224, the magnet 2112 on the bottom cover 211 is attracted to the metal member 223, so that the rotating cover 221 is attracted to the bottom cover 211, thereby achieving the effect of attracting and closing the second dust removal port 2101, further simplifying the structure and facilitating operation. Here, the metal member 223 can be an iron metal sheet, and the magnet 2112 is attracted to the iron metal sheet.

[0084] In a specific implementation, a magnet slot 2113 is provided on the side of the bottom cover 211 facing away from the rotating cover 221, and the magnet 2112 is clamped in the magnet slot 2113. This facilitates replacement of the magnet 2112 and facilitates subsequent maintenance.

[0085] To further enhance the stability of the rotating cover 221 when closing the second dust removal port 2101, a torsion spring 225 is further included. The torsion spring 225 is sleeved on the fixed shaft 222, and a portion of the torsion spring 225 abuts the rotating cover 221. The torsion spring 225 is configured to apply a force to the rotating cover 221 to tilt toward the bottom cover 211. The torsion spring 225 abuts the rotating cover 221. The specific use of the torsion spring 225 is not limited in this embodiment of the present application. The torsion spring 225 constantly applies a force to tilt the rotating cover 221 toward the bottom cover 211, ensuring that the rotating cover 221 tightly covers the second dust removal port 2101. With this configuration, the torsion spring 225 applies a force to tilt the rotating cover 221 toward the bottom cover 211. It is understood that, under the premise that the rotating cover 221 and the bottom cover 211 are closed by suction, the force of the torsion spring 225 achieves a tight closure, thereby enhancing the closure stability of the second dust removal port 2101. In addition, after the handheld device is connected to the base station and the automatic dust collection is completed, the rotating cover 221 can automatically drive the rotating cover 221 to flip and close under the force of the torsion spring 225, further simplifying the operation steps and improving reliability.

[0086] Continue to refer to Figure 2 and Figure 3 As shown, combined with Figure 8 and Figure 9 The hinge hole 2211 and the magnetic part 224 are respectively located on both sides of the rotating cover 221 along the first direction. The length direction of the fixed axis 222 is parallel to the second direction, and the first direction is perpendicular to the second direction. Figure 2 As shown by the X arrow in the middle, the second reverse direction is as follows Figure 2 As indicated by the Y arrow in the middle. The hinge hole 2211 and the magnetic portion 224 are located on either side of the rotating cover 221 along the first direction, respectively. This allows force to be applied to both ends of the rotating cover 221 along the first direction, further tightening the rotating cover 221 and improving its sealing performance. By arranging the length of the fixed shaft 222 parallel to the second direction and the first and second directions perpendicular, the axis of the fixed shaft 222 can be used as the rotation center of the rotating cover 221, improving transmission efficiency.

[0087] In some embodiments, to improve sealing, the secondary end cap assembly 220 further includes a first seal 226. A boss 2212 is provided along the circumferential edge of the rotating cover 221. Specifically, the boss 2212 is provided on the side of the rotating cover 221 facing the bottom cover 211. The first seal 226 is sleeved onto the boss 2212 to seal the second dust removal port 2101. The first seal 226 may be a rubber ring. By sleeved onto the boss 2212, the sealing structure is simplified, the sealing between the rotating cover 221 and the bottom cover 211 is improved, and impurities collected in the dust cup body 100 are effectively prevented from leaking through the gap between the rotating cover 221 and the bottom cover 211. Furthermore, after the rotating cover 221 closes the second dust removal port 2101, the first seal 226 can also provide an interference fit with the rotating cover 221 at the second dust removal port 2101, further improving the stability of the rotating cover 221.

[0088] In some embodiments, the primary end cap assembly 210 further includes a second seal 213. The bottom cap 211 is provided with a sealing groove 2114 along its circumference. The second seal 213 is disposed within the sealing groove 2114, and a portion of the second seal 213 is located outside the sealing groove 2114 to seal the first dust removal port 102. By disposing the second seal 213 within the sealing groove 2114 and a portion of the second seal 213 outside the sealing groove 2114, the sealing structure between the bottom cap 211 and the dust cup body 100 can be simplified, effectively preventing impurities inside the dust cup body 100 from leaking through the gap between the dust cup body 100 and the bottom cap 211 when the dust cup body 100 is in operation.

[0089] It is understandable that the second sealing member 213 may also be a rubber ring, and the contour of the second sealing member 213 corresponds to the contour of the sealing groove 2114 to improve the sealing performance.

[0090] In some embodiments, reference Figure 2 and Figure 3 As shown, combined with Figure 7 The clamping assembly 230 includes a clamping block 231 and an elastic member 232 .

[0091] A mounting groove 104 is provided on the side wall of the dust cup body 100 , and the clamping block 231 is rotatably connected in the mounting groove 104 . The clamping block 231 has a clamping joint 233 , and the clamping joint 233 protrudes from the mounting groove 104 .

[0092] A snap-fitting groove 2115 is defined on the bottom cover 211 ; the elastic member 232 is disposed between the snap-fitting joint 233 and the inner wall of the mounting groove 104 , and is configured to apply elastic force to the end of the snap-fitting block 231 away from the snap-fitting joint 233 , so that the snap-fitting joint 233 is snap-fitted into the snap-fitting groove 2115 .

[0093] The snap-fitting block 231 is rotatably connected in the mounting slot 104, and the elastic member 232 exerts a force on one end of the snap-fitting block 231 away from the snap-fitting joint 233, so that the snap-fitting joint 233 always has a tendency to rotate toward the snap-fitting slot 2115, so that the snap-fitting joint 233 is stably clamped in the snap-fitting slot 2115, thereby improving the connection stability. When the user needs to contact the lock of the bottom cover 211, he only needs to press the end of the snap-fitting block 231 away from the snap-fitting joint 233 to overcome the elastic force of the elastic member 232 and disengage the snap-fitting joint 233 from the snap-fitting slot 2115. This structure is simple, convenient for user operation, and helps to improve the user experience.

[0094] The elastic member 232 here can be an elastic rubber pad or a spring. In the embodiment of the present application, there is no restriction on the specific structure and usage of the elastic member 232. It is only necessary for the elastic member 232 to be able to exert a force on one end of the clamping block 231 away from the clamping joint 233, so that the clamping joint 233 always has a tendency to rotate toward the clamping groove 2115, so that the clamping joint 233 can be stably clamped in the clamping groove 2115.

[0095] Of course, the clamping block 231 is rotatably connected in the installation slot 104 , the rotation axis of the clamping block 231 is set in the middle position of the clamping block 231 , and the elastic member 232 and the clamping joint 233 are respectively set on both sides of the axial direction of the rotation axis of the clamping block 231 .

[0096] In some embodiments, the present application also provides a handheld device, referring to Figures 6 to 9 As shown, the handheld device includes a handheld body 20 and the aforementioned dust cup structure 10, which is movably connected to the handheld body 20. The specific structure of the dust cup structure 10 has been described above and will not be repeated here. The handheld device has all the beneficial technical effects of the aforementioned dust cup structure 10 and can facilitate dust emptying operations when the handheld device is used alone or in conjunction with a base station.

[0097] The handheld body 20 includes a drive member 30 for providing suction to draw impurities from the surface to be cleaned into the dust cup body. To enhance the safety of the drive member 30 and prevent impurities from accidentally entering the drive member 30, the dust cup structure 10 further includes a top cover assembly 300 and a filter 400. The top cover assembly 300 is positioned over the upper end of the dust cup body and is movably connected to the handheld body 20. The filter 400 is disposed within the top cover assembly 300 to prevent impurities within the dust cup body from entering the drive member 30. Specifically, the filter 400 includes at least one of a sponge 410 and a HEPA filter 420, although this embodiment of the present application does not impose any specific limitations on this aspect.

[0098] The present application also provides a cleaning device comprising a base station and the aforementioned handheld device, wherein the base station is movably connected to the handheld device. The cleaning device has all the beneficial technical effects of the aforementioned handheld device and dust cup structure 10, facilitating dust removal operations in a variety of user scenarios, thereby enhancing the user experience. The cleaning device may be a vacuum cleaner, a floor scrubber, a sweeper, a vacuum cleaner, or other similar device.

[0099] The embodiment of the present application provides a dust cup structure 10, a handheld device and a cleaning device, wherein the dust cup structure 10 includes: a dust cup body 100, a dust collecting chamber 101 in the dust cup body 100, and the dust collecting chamber 101 has a first dust removal port 102; an end cover structure 200, the end cover structure 200 includes a primary end cover assembly 210, a secondary end cover assembly 220 and a snap assembly 230; the primary end cover assembly 210 is arranged at the first dust removal port 102 and is rotatably connected to the dust cup body 100 to flip open or close the first dust removal port 102; the snap assembly 230 is connected to the dust cup body 100 The first-level end cover assembly 210 is connected, and the snap-on assembly 230 is at least partially movably buckled on the first-level end cover assembly 210 to lock or unlock the first-level end cover assembly 210; the first-level end cover assembly 210 has a second dust removal port 2101, and the second dust removal port 2101 is connected to the dust collecting chamber 101. The second-level end cover assembly 220 is arranged at the second dust removal port 2101 and is rotatably connected to the first-level end cover assembly 210 to flip open or close the second dust removal port 2101; the second-level end cover assembly 220 is configured to open the second dust removal port 2101 under the suction force of the base station when the handheld device is connected to the base station. The user only needs to operate the snap-on assembly 230 to open the first dust removal port 102 for dumping dust when the dust cup structure 10 is used alone, which has the effect of facilitating the dust dumping operation; by setting the second dust removal port 2101 on the first-level end cover assembly 210, the second dust removal port 2101 is connected to the dust collecting chamber 101, and the second-level end cover assembly 220 is set at the second dust removal port 2101, and is rotatably connected to the first-level end cover assembly 210 to flip open or close the second dust removal port 2101. The setting method of the above structure can facilitate the dust dumping operation of the handheld device when it is used alone or in conjunction with the base station, so as to solve the problem that when the user uses the handheld device alone and needs to manually dump the dust, the operation is inconvenient, and manual dust dumping and automatic dust collection cannot be taken into account at the same time.
