Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment, and in particular to a vacuum cleaner. Background Technology

[0002] Some existing vacuum cleaners, in pursuit of a simple and compact appearance, have opted to simplify the product's structure. For example, the airflow guiding structure inside the dust cup has been replaced with an inner cylinder. One axial end of the inner cylinder is connected to the inner surface of the dust cup, and the other axial end of the inner cylinder abuts against the dust cup lid. The inner cylinder has a notch to connect the inner and outer spaces of the inner cylinder. In the process of realizing this utility model, the inventors found that the cyclone separation effect of this structure is not good, the vacuum cleaner's dust collection efficiency is low, and dust is prone to clogging the dust cup's air outlet. Utility Model Content

[0003] One objective of this invention is to provide a vacuum cleaner with better cyclone separation effect in the dust cup, higher dust collection efficiency, and less clogging of the dust cup outlet.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] In any of the above technical solutions, the dust cup further includes a cyclone structure, which is disposed at the end of the inner cylinder facing the dust outlet. The cyclone structure is in contact with or has a gap distance from the cup lid, and the inner cylinder is connected to the dust collection space along the cyclone structure.

[0008] In any of the above technical solutions, the surface of the inner cylinder, except for the air inlet, is configured as a non-notch structure; or one or more dust discharge notches are provided on the side wall of the inner cylinder, and the dust discharge notches penetrate the side wall of the inner cylinder along the wall thickness direction.

[0009] In any of the above technical solutions, the cross-section of the inner cylinder is set to be circular or elliptical; and / or the cross-section of the side wall of the cup body is set to be quadrilateral; and / or the inner cylinder is spaced apart from the side wall of the cup body at each circumferential position.

[0010] In any of the above technical solutions, a connecting structure is provided on the inner surface of the cup body at a position around the air outlet, the dust cup also includes a HEPA structure, the HEPA structure is located inside the inner cylinder and is radially spaced from the inner cylinder, one end of the HEPA structure is connected to the connecting structure, the other end of the HEPA structure is positioned towards the cup lid and has a gap between it and the cup lid; and / or a grille is integrally formed on the cup body, the grille being positioned corresponding to the air outlet.

[0011] In any of the above technical solutions, the vacuum cleaner is provided with a handle, and the handle is provided with a dust removal button; one end of the cup lid is rotatably connected to the cup body, and the other end of the cup lid is provided with a locking part that is detachably locked to the cup body; the vacuum cleaner also includes a transmission structure, which is configured to drive between the dust removal button and the locking part; the dust removal button can be pressed to drive the transmission structure, thereby releasing the locking part from the cup body.

[0012] In any of the above technical solutions, at least one side wall of the cup body is provided with a sandwich section, the sandwich section is hollowly disposed, an opening is formed at one end of the sandwich section near the cup lid, and a protrusion is provided on the inner surface of the sandwich section near the opening of the sandwich section. When the cup lid is closed with the dust discharge port, the snap-fit ​​part extends into the sandwich section along the opening of the sandwich section and snaps into the protrusion; the transmission structure includes a movable rod, one end of the movable rod passes through the sandwich section and corresponds to the snap-fit ​​part, and the other end of the movable rod extends to the dust discharge button.

The end of the main unit near the dust cup has an opening, and the end of the dust cup body near the main unit has a top wall. The top wall blocks the opening of the main unit. A mounting base protrudes from the side of the top wall facing the main unit. An airflow driving device is provided inside the main unit, and the airflow driving device is arranged corresponding to the mounting base.

[0015] When the vacuum cleaner of this application is working, a negative pressure is formed at the air inlet of the dust cup. This negative pressure drives the airflow and dust to be drawn into the inner cylinder along the air inlet channel for swirling. The dust is then thrown into the dust collection space for storage due to centrifugal force. Since there is a gap between the end of the inner cylinder facing the dust outlet and the cup lid, the swirling in the inner cylinder can be concentrated and maintained closer to the air outlet. The centrifugal force of cyclone separation is greater, which can more efficiently throw the dust in the airflow into the dust collection space. The cyclone separation effect is better. In this way, the dust will not keep rotating in the inner cylinder, the power loss of the airflow is reduced, the vacuum cleaner has higher dust collection efficiency, and because the dust is discharged more efficiently, the problem of dust clogging the air outlet of the dust cup is better avoided.

Furthermore, it should be noted that this specification describes many features.

[0040] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided to make the description of the present invention more comprehensive and complete, and to fully convey the concept of the exemplary embodiments to those skilled in the art. The drawings are merely illustrative of the present invention and are not necessarily drawn to scale.

[0041] Some embodiments of this utility model provide a vacuum cleaner.

[0042] The vacuum cleaner includes a dust cup 10, which includes a cup body 11 and a cup lid 14.

[0043] The cup body 11 has an inner cylinder 12 inside. At least a portion of the inner cylinder 12 is spaced apart from the side wall of the cup body 11 along the circumferential direction to define a dust collection space 13 between the inner cylinder 12 and the side wall of the cup body 11. The dust collection space 13 is connected to the inner cylinder 12. One end of the cup body 11 is provided with a dust discharge port 112. The end of the cup body 11 away from the dust discharge port 112 is provided with an air outlet 111 connected to the inner cylinder 12. The inner cylinder 12 is provided with an air inlet 121 for tangential air intake. The cup body 11 is provided with an air intake channel 113 connected to the air inlet 121. The cup lid 14 is closable and disposed at the dust discharge port 112. One axial end of the inner cylinder 12 is disposed towards the dust discharge port 112 and is spaced apart from the cup lid 14.

[0044] It is understandable that a vacuum cleaner is a device that uses an airflow drive device to operate, which draws air from the air outlet 111 of the dust cup 10, thereby creating a negative air pressure inside the dust cup 10, and using the negative air pressure to suck up dust and debris.

[0045] In this vacuum cleaner, when the airflow drive device is working, it draws air from the dust cup 10 along the air outlet 111, creating a negative pressure at the air inlet 121 of the dust cup 10. This negative pressure drives the airflow and dust to be drawn into the inner cylinder 12 along the air inlet channel 113 for swirling. The dust is then thrown into the dust collection space 13 for storage due to centrifugal force. Since there is a gap between the end of the inner cylinder 12 facing the dust outlet 112 and the cup lid 14, the swirling air in the inner cylinder 12 can be concentrated and maintained closer to the air outlet 111. The centrifugal force of the cyclone separation is greater, which can more efficiently throw the dust in the airflow into the dust collection space 13. The cyclone separation effect is better. In this way, the dust will not keep rotating in the inner cylinder 12, the power loss of the airflow is reduced, the vacuum cleaner has higher suction efficiency, and because the dust is discharged more efficiently, the problem of dust clogging the air outlet 111 of the dust cup 10 is better avoided.

[0046] Optionally, the vacuum cleaner of this application can be a portable vacuum cleaner. In this way, based on the cyclone separation achieved by the inner cylinder 12, the inner cylinder 12 does not occupy too much of the volume of the dust cup 10. Under the premise of ensuring the effective volume of the dust cup 10, the miniaturization of the dust cup 10 and the entire vacuum cleaner can be fully realized, thereby further improving the portability of the vacuum cleaner.

[0047] Of course, the vacuum cleaner of this application is not limited to a portable vacuum cleaner. It is understood that the structure of the dust cup 10 including the inner cylinder 12 can also be applied to vacuum cleaners of various types such as canister vacuum cleaners, upright vacuum cleaners, robot vacuum cleaners, and floor scrubbers without conflict, so that the vacuum cleaner can also be selected as any one of canister vacuum cleaners, upright vacuum cleaners, robot vacuum cleaners, and floor scrubbers.

[0048] The following will be combined with the appendix Figures 1 to 17 The vacuum cleaner of this application will be specifically described through several embodiments.

[0049] Example 1:

[0050] Please see Figure 1 and Figure 2 , Figure 1 and Figure 2 The three-dimensional structure of the vacuum cleaner in this embodiment is shown from different perspectives.

[0051] This vacuum cleaner may include a main unit 20, a dust cup 10, and a hose 60.

[0052] The dust cup 10 includes a cup body 11 and a cup lid 14.

[0053] The cup body 11 of the dust cup 10 is connected to the main unit 20. Optionally, the cup body 11 of the dust cup 10 and the main unit 20 can be fixedly connected. For example, the cup body 11 of the dust cup 10 is fixed to the main unit 20 by screws. Alternatively, in other embodiments, the cup body 11 of the dust cup 10 and the main unit 20 can also be connected in a way that facilitates disassembly, such as by snap-fit.

[0054] The horizontal cross-sectional shape of the main unit 20 is the same as that of the dust cup 10. Thus, the cup body 11 of the dust cup 10 is approximately the same size and dimensions in all directions as the main unit 20. Without increasing the overall horizontal dimensions of the vacuum cleaner to achieve a smaller appearance, the cup body 11 of the dust cup 10 can have the largest possible volume, ensuring sufficient capacity. This reduces the need for frequent emptying of dust, and provides more space within the dust cup 10 to ensure effective separation of dust and air, allowing the vacuum cleaner to maintain greater and more stable suction power, thereby improving its cleaning efficiency.

[0055] Optionally, the host 20 can be configured as follows: Figure 1 and Figure 2The dust cup 10 is also configured in the shape of a quadrilateral or similar quadrilateral prism as shown. Figure 1 and Figure 2 As shown, the main body 20 and the dust cup 10 have essentially the same horizontal cross-sectional shape, both being quadrilaterals or similar quadrilaterals of comparable size. The lower end of the main body 20 connects with the upper end of the dust cup 10, thus forming a quadrilateral or similar quadrilateral prism-shaped vacuum cleaner body together. This results in a more regular product appearance, more stable support of the dust cup 10 for the main body 20, and a larger volume of the dust cup 10 in the horizontal direction.

[0056] Of course, in other embodiments, the main unit 20 and the dust cup 10 may also be cylindrical, elliptical, etc., and are not limited to the quadrilateral or similar quadrilateral prism shapes listed in this embodiment.

[0057] Optionally, such as Figure 1 and Figure 2 As shown, the end of the main unit 20 facing the dust cup 10 is correspondingly and smoothly transitioned to the end of the dust cup 10 facing away from the dust outlet 112. In other words, the lower end of the peripheral wall of the main unit 20 and the upper end of the peripheral wall of the cup body 11 of the dust cup 10 are correspondingly and smoothly transitioned. In this way, the outer surface of the product has better continuity, is easier to store, and the surface of the product is less likely to accumulate dirt, making it easier to clean the surface of the product.

[0058] The main unit 20 is equipped with a battery pack 40 for powering the vacuum cleaner. The battery pack 40 can be a rechargeable battery or a battery that connects directly to a power outlet. Preferably, using a rechargeable battery eliminates the need for a cord, improving portability and enhancing safety when using the vacuum cleaner by hand, reducing the risk of electric shock. Furthermore, by placing the battery pack 40 on the main unit 20, compared to the traditional structure where the battery pack 40 is located around the dust cup 10, the battery pack 40 avoids taking up space in the dust cup 10, achieving product miniaturization while better preserving the volume of the dust cup 10.

[0059] Please see Figure 3 and Figure 4 , Figure 3 and Figure 4 The structure of the vacuum cleaner in this embodiment is shown in the front view and left view.

[0060] like Figure 3 and Figure 4As shown, the battery pack 40 is located on the side of the main unit 20 facing away from the dust cup 10. That is, the battery pack 40 and the dust cup 10 are located at opposite ends of the main unit 20. This makes the vacuum cleaner's center of gravity more stable, makes it easier to use when holding the vacuum cleaner, and makes the vacuum cleaner more stable and less likely to tip over when placed.

[0061] Optionally, the dust cup 10 is located at the lower end of the main unit 20, and the battery pack 40 is located at the upper end of the main unit 20. When the vacuum cleaner is placed vertically, the dust cup 10, the main unit 20, and the battery pack 40 are arranged sequentially in the vertical direction, with their centers of gravity roughly on the same vertical line, making it less likely for the vacuum cleaner to tip over when placed vertically. Even when the vacuum cleaner is placed horizontally, that is, when the dust cup 10, the main unit 20, and the battery pack 40 are arranged sequentially from left to right or from right to left, the problem of the vacuum cleaner tipping over is not likely to occur.

[0062] More specifically, the main unit 20 is equipped with an airflow drive device, which, as the name suggests, is a component used to drive airflow. Specifically, it can be an assembly including a motor 31 and fan blades (not shown in the figure). Of course, in other embodiments, the airflow drive device can also be a fan. The airflow drive device is located at the interval between the battery pack 40 and the dust cup 10. This allows for a more accurate alignment of the centers of gravity of the battery pack 40, dust cup 10, and main unit 20 along the same longitudinal line, thereby better promoting the stability and portability of the vacuum cleaner.

[0063] Please see Figure 5 , Figure 5 The structure of the vacuum cleaner in this embodiment with the battery pack 40 separated from the main unit 20 is shown.

[0064] A battery slot 211 is recessed on the surface of the main unit 20 on the side opposite to the dust cup 10, and the battery pack 40 is detachably and slidably connected to the battery slot 211. This detachable and slidable connection makes loading and unloading the battery pack 40 easier and faster, and more convenient for the user. More specifically, slide rails 42 are provided on both opposite sides of the battery pack 40, and slide grooves 2111 are provided on both opposite side walls of the battery slot 211. The slide rails 42 are detachably accommodated within the slide grooves 2111 and can slide along the slide grooves 2111, achieving a detachable sliding connection between the battery pack 40 and the battery slot 211. This also provides assembly positioning between the battery pack 40 and the battery slot 211, preventing the battery pack 40 from shaking within the battery slot 211 and causing poor contact.

[0065] Optionally, the battery pack 40 and the circuit board inside the main unit 20 can be detachably electrically connected through structures such as conductive contacts and / or conductive springs. For example, the battery pack 40 is provided with conductive contacts and / or conductive springs, and the battery slot 211 is provided with conductive contacts and / or conductive springs that are electrically connected to the circuit board inside the main unit 20. When the battery pack 40 is assembled in the battery slot 211, the conductive contacts and / or conductive springs on the battery pack 40 are in contact with the conductive contacts and / or conductive springs in the battery slot 211. When the battery pack 40 leaves the battery slot 211, the conductive contacts and / or conductive springs on the battery pack 40 are separated from the conductive contacts and / or conductive springs in the battery slot 211.

[0066] Optionally, such as Figures 1 to 4 As shown, the main unit 20 is equipped with a handle 22, which makes it convenient for users to hold and use the vacuum cleaner by hand.

[0067] Of course, it is understood that the handle 22 is not limited to being located on the host 20. In other embodiments, the handle 22 may also be located on the dust cup 10.

[0068] Optionally, the handle 22 is positioned on the side of the main unit 20 facing away from the dust cup 10. More specifically, at least a portion of the handle 22 is located on the side of the battery pack 40 away from the dust cup 10. In this way, the dust cup 10, main unit 20, battery pack 40, and handle 22 are arranged approximately in sequence, and the center of gravity of the handle 22, the dust cup 10, the main unit 20, and the battery pack 40 are approximately on the same vertical line, making it easier for the user to hold the vacuum cleaner using the handle 22.

[0069] In detail, such as Figures 1 to 4 As shown, the end face of the handle 22, which is furthest from the dust cup 10 of the main unit 20, is arched. This arching of the handle 22 creates a clearance space 23 between the main unit 20 and the handle 22. The battery pack 40 is positioned on the surface of the main unit 20 near the clearance space 23. Firstly, the clearance space 23 allows the user's hand to pass through when holding the handle 22, making it more comfortable. Secondly, it fully utilizes part of the clearance space 23 to accommodate the battery pack 40, solving the problem of battery pack 40 inclusion while also achieving a miniaturized product design. Furthermore, the sequential arrangement of the handle 22, battery pack 40, main unit 20, and dust cup 10 ensures that the center of gravity of the handle 22, battery pack 40, main unit 20, and dust cup 10 are aligned, making it easier for the user to hold the vacuum cleaner.

[0070] More in detail, such as Figure 5As shown, a battery slot 211 is recessed on the side of the main unit 20 near the clearance space 23, and the battery pack 40 is detachably slidably connected to the battery slot 211. While assembling the battery pack 40, the recessed battery slot 211 on the side of the main unit 20 near the clearance space 23 allows the battery slot 211 to face the clearance space 23. When the battery pack 40 is located within the battery slot 211, it can dissipate heat towards the clearance space 23, thus preventing the battery pack 40 from becoming too hot to handle.

[0071] Optionally, such as Figure 5 As shown, a power cable 41 is fixedly or detachably provided on the battery pack 40, or the battery pack 40 is provided with a power interface. This facilitates repeated charging and use of the battery pack 40.

[0072] Please see Figure 6 , Figure 6 The cross-sectional structure of the vacuum cleaner in this embodiment is shown.

[0073] Please see Figure 7 , Figure 7 The exploded structure of the vacuum cleaner in this embodiment is shown.

[0074] Please see Figure 8 , Figure 8 The three-dimensional structure of the dust cup 10 body 11 in this embodiment is shown.

[0075] Combination Figure 6 , Figure 7 and Figure 8 It can be understood that the dust cup 10 specifically includes a side wall, a top wall 110 disposed at the upper end of the side wall of the dust cup 10, a dust discharge port 112 disposed at the lower end of the side wall of the dust cup 10, and a cup lid 14 is disposed at the dust discharge port 112 in an openable and closable manner.

[0076] The main unit 20 has an opening at the bottom. The lower end of the peripheral wall of the main unit 20 is opposite to and smoothly transitions to the upper end of the peripheral wall of the dust cup 10. The top wall 110 of the dust cup 10 seals the opening at the bottom of the main unit. In this way, the bottom wall of the main unit 20 is omitted. When the main unit 20 is connected to the dust cup 10, the opening at the bottom of the main unit 20 is sealed at the same time, which simplifies both the product structure and the product assembly process.

[0077] The cup body 11 has an inner cylinder 12 inside. At least a portion of the inner cylinder 12 is spaced apart from the side wall of the cup body 11 along the circumferential direction to define a dust collection space 13 between the inner cylinder 12 and the side wall of the cup body 11. The dust collection space 13 is connected to the inner cylinder 12. An air outlet 111 connected to the inner cylinder 12 is provided at the end of the cup body 11 away from the dust discharge port 112. One axial end of the inner cylinder 12 is provided corresponding to the cup lid 14 and is spaced apart from the cup lid 14. The inner cylinder 12 is provided with an air inlet 121 for tangential air intake. The cup body 11 is provided with an air intake channel 113 connected to the air inlet 121. The air outlet 111 of the dust cup 10 is connected to the main unit 20.

[0078] When the airflow drive device inside the main unit 20 is working, the dust cup 10 draws airflow and dust into the inner cylinder 12 along the air inlet channel 113, and swirls inside the inner cylinder 12. Since the inner cylinder 12 is connected to the dust collection space, during the swirling of airflow and dust inside the inner cylinder 12, the dust is thrown to the dust collection space outside the inner cylinder 12 for collection due to centrifugal force, while the airflow is drawn into the main unit 20 by the airflow drive device along the air outlet 111.

[0079] Because there is a gap between the end of the inner cylinder 12 facing the dust outlet 112 and the cup lid 14, the swirling air inside the inner cylinder 12 can be concentrated and maintained at a position closer to the air outlet 111. The centrifugal force of the cyclone separation is greater, which can more efficiently throw the dust in the airflow into the dust collection space 13. The cyclone separation effect is better. In this way, the dust will not keep rotating in the inner cylinder 12, the power loss of the airflow is reduced, the dust collection efficiency of the vacuum cleaner is higher, and because the dust is discharged more efficiently, the problem of dust clogging the dust cup air outlet 111 is also better avoided.

[0080] Specifically, such as Figure 8 As shown, the inner cylinder 12 is a cylindrical structure with one side wall encircling the perimeter. The interior of the inner cylinder 12 is hollow, serving as a space for airflow and dust to swirl. The air inlet 121 is located on the side wall of the inner cylinder 12, preferably tangentially positioned along the inner cylinder 12. This allows airflow and dust to enter the inner cylinder 12 tangentially for more efficient swirling, thereby reducing airflow power loss and improving cyclone separation efficiency. Furthermore, because the inner cylinder 12 is a hollow cylindrical structure, it also serves a containment function, thus not significantly affecting the effective volume of the dust cup 10, and allowing for a more compact design of the vacuum cleaner.

[0081] Optionally, combined Figure 3 , Figure 6 and Figure 8As shown, the air inlet channel 113 is a tube. The air inlet channel 113 is located inside the dust cup 10, and one end of the air inlet channel 113 extends to the air inlet 121 of the inner cylinder 12. An installation port 201 is provided on the side wall of the dust cup 10, and the other end of the air inlet channel 113 extends to the installation port 201.

[0082] Alternatively, the air inlet channel 113, the inner cylinder 12, and the cup body 11 can be integrally formed.

[0083] Optionally, combined Figure 1 , Figure 2 and Figure 6 It is understood that a hose fixing member 212 is provided on the outer surface of the dust cup 10. One end of the hose 60 is connected to the mounting port 201. The hose 60 is wound around the circumference of the cup body 11, and the other end of the hose 60 is detachably connected to the hose fixing member 212, so that the hose 60 is stably and reliably wound around the dust cup 10, which facilitates the storage of the product.

[0084] Of course, this application is not limited to this. In other embodiments, the hose fixing member 212 can be disposed on the outer surface of the host 20, the hose 60 can be wrapped around the dust cup 10 or the outer periphery of the host 20, and the end of the hose 60 away from the mounting port 201 can be detachably connected to the hose fixing member 212 on the surface of the host 20.

[0085] Alternatively, the hose retainer 212 can be configured as follows: Figure 6 The slot formed by the C-shaped ribs shown in the diagram secures the hose 60 within it. The slot does not occupy the internal space of the dust cup 10, thus not affecting its effective volume. Alternatively, in other embodiments, the hose fixing member 212 can be configured as a groove formed by a recess in the surface of a component (such as the dust cup 10 or the main unit 20), or a Velcro strap can be provided between the dust cup 10 or the main unit 20 and the hose 60, allowing the hose 60 to adhere to the surface of the dust cup 10 or the main unit 20.

[0086] Optionally, the inner cylinder 12 can be configured as follows: Figure 8 The cylindrical shape shown in the diagram reduces resistance during the airflow and dust swirling process within the inner cylinder 12, resulting in higher efficiency in separating dust and airflow through the cyclone.

[0087] Of course, this application is not limited to this. In other embodiments, the inner cylinder 12 may also be configured as an elliptical cylinder, a conical cylinder, etc.

[0088] Optionally, such as Figure 8As shown, the inner cylinder 12 is radially spaced from the side wall of the cup body 11 at all circumferences, forming a dust collection space 13 around the outer periphery of the inner cylinder 12. This allows for more even dust collection, improving cyclone separation efficiency and achieving a larger dust volume. Furthermore, the spaced structure between the inner cylinder 12 and the side wall of the cup body 11 prevents dust from getting stuck, facilitating the complete removal of dust from the dust cup 10 during emptying and reducing cleaning operations for the user.

[0089] Alternatively, the dust cup 10 is generally a prism with a quadrilateral or similar quadrilateral cross-section on the side wall of the cup body 11, and the inner cylinder 12 is generally a cylinder with a circular cross-section on the side wall. The inner cylinder 12 and the side wall of the cup body 11 of the dust cup 10 are radially spaced apart, so that the volume of the dust collection space 13 between the inner cylinder 12 and the side wall of the cup body 11 of the dust cup 10 is larger.

[0090] Optionally, one end of the lid 14 is rotatably connected to the cup body 11, and the other end of the lid 14 is provided with a locking part 141, which is detachably locked to the cup body 11. A dust removal button 241 is provided on the handle 22. The vacuum cleaner also includes a transmission structure, which is disposed between the dust removal button 241 and the locking part 141. The transmission structure is used to act on the locking part 141 under the drive of the dust removal button 241, so that the locking part 141 releases the cup body 11. In this way, the user can perform dust removal operation with one hand. That is, when the user holds the handle 22, he / she can press the dust removal button 241 on the handle 22 to achieve one-handed one-button control to open the lid 14, making the product simpler and more convenient to use.

[0091] Optionally, the dust removal button 241 is located on the side of the handle 22 facing the user. This makes it easier for the user to press the dust removal button 241 while holding the handle.

[0092] Optionally, the dust outlet 112 is located at the end of the cup body 11 away from the main unit 20. In this way, when the cup cover 14 is opened, the bottom of the dust cup 10 can be directly drained without the user having to flip the dust cup 10 to empty it, making the product more convenient to use.

[0093] Please see Figure 9 , Figure 9 The exploded view of the dust removal button 241, handle 22, and movable lever 50 is shown.

[0094] like Figure 9As shown, the transmission structure includes a movable rod 50, which is movably mounted on the main unit 20 and the cup body 11. One end of the movable rod 50 is connected to the dust removal button 241, and the other end of the movable rod 50 is positioned corresponding to the locking part 141. The dust removal button 241 can be pressed to drive the movable rod 50 to move relative to the main unit 20 and the cup body 11, thereby driving the locking part 141 to release the locking part 141 from the cup body 11. By using a movable rod 50 to transmit power between the dust removal button 241 and the locking part 141, compared to a multi-link transmission structure, dead-point problems can be avoided, improving the success rate of opening the cup lid 14 with the dust removal button 241 on the first attempt, and the transmission efficiency is also higher. This means that the user needs to apply less force to press the dust removal button 241, making it more suitable for single-handed dust removal operations.

[0095] More in detail, such as Figure 9 As shown, the movable rod 50 includes a top beam 51 and at least one side beam 52. An extension arm 55 is fixedly connected between one end of the top beam 51 and one end of the side beam 52. Both the side beam 52 and the top beam 51 are inclined relative to the extension arm 55. The end of the top beam 51 away from the extension arm 55 is connected to the dust removal button 241. The end of the side beam 52 away from the extension arm 55 serves as a trigger end 501. The trigger end 501 is used to cooperate with the locking part 141 so that the locking part 141 contacts and engages with the cup body 11. The extension arm 55 creates a bend between the top beam 51 and the side beam 52. This facilitates coordination and consideration of the positions of the dust removal button 241 and the locking part 141. For example, the locking part 141 can be positioned closer to the edge of the lid 14, making the locking more stable and reducing dust accumulation on the locking part 141. The dust removal button 241 on the handle 22 can be positioned slightly inside the edge of the main unit 20, making it easier for the user to operate the dust removal button 241 when holding the handle 22. Therefore, the relative tilt of the extension arm 55 with the top beam 51 and the side beam 52 effectively meets the differentiated positional requirements of the dust removal button 241 and the locking part 141. On the other hand, it gives the movable rod 50 greater structural rigidity and makes it less prone to deformation, thereby enabling more precise transmission between the dust removal button 241 and the locking part 141, achieving more accurate lid opening control.

[0096] Further optional, such as Figure 9As shown, the movable rod 50 includes two side beams 52, which are spaced apart. The extension arms 55 of the two side beams 52 are angled and connected to the top beam 51. At least one reinforcing rib 53 connects the two side beams 52. The cup lid 14 has two locking parts 141 spaced apart, which are respectively locked to the cup body 11. Both side beams 52 have trigger ends 501, which are corresponding to the two locking parts 141, for releasing the locking parts 141 from the cup body 11. The two locking parts 141 spaced apart on the cup lid 14, which are respectively locked to the cup body 11, can achieve a more reliable connection between the cup lid 14 and the cup body 11, and the cup lid 14 is less likely to wobble when locked to the cup body 11. The movable lever 50 is equipped with two side beams 52 and two extension arms 55, allowing the movable lever 50 to branch out from one end of the top beam 51, extending into two extension arms 55 and connecting to the side beams 52. This allows the same movable lever 50 to control the disengagement of the two locking parts 141 from the cup body 11, achieving one-button opening control. It also saves on the size and weight of the movable lever 50, making one-button opening easier and contributing to overall product weight reduction, thus improving portability. The structure with at least one reinforcing rib 53 connecting the two side beams 52 reduces the risk of deformation of the movable lever 50, resulting in more precise and reliable transmission between the dust removal button 241 and the locking part 141.

[0097] Alternatively, the movable rod 50 may be a one-piece molded component.

[0098] Alternatively, the top beam 51 and the extension arm 55 are movably disposed within the main unit 20, and the side beam 52 is movably disposed within the dust cup 11. In this way, the top beam 51 and the extension arm 55, which have a bent transition structure on the movable rod 50, are both located within the main unit 20. Only a small amount of space needs to be allocated on the dust cup 10 to accommodate the side beam 52, which can save the space occupied by the movable rod 50 in the dust cup 10, thereby better ensuring the volume of the dust cup 10.

[0099] Furthermore, optionally, combined with Figure 8 and Figure 9 It is understood that at least one side wall of the cup body 11 is provided with a sandwich section 114, which is hollowly provided, and the side beam 52 is movably inserted through the sandwich section 114.

[0100] One or more first ribs 115 are protruding on the inner surface of the interlayer 114, and one or more second ribs 521 are protruding on the surface of the side beam 52. The first ribs 115 and the second ribs 521 cooperate to a certain extent to limit the lateral movement of the side beam 52 in the interlayer 114, so that the trigger end 501 can keep corresponding to the snap-fit ​​part 141 and avoid misalignment. Furthermore, the first ribs 115 and the second ribs 521 separate the surface of the side beam 52 from the surface of the interlayer 114, which can reduce the contact area between the side beam 52 and the inner surface of the interlayer 114 to a certain extent. This can reduce the friction during the movement of the movable rod 50, thereby saving the driving force of the dust removal button 241 and making the operation of the user easier.

[0101] Optionally, such as Figure 8 and Figure 9 As shown, there are two first protruding ribs 115 arranged at intervals, and there are also two second protruding ribs 521 on the movable rod 50 arranged at intervals. The two first protruding ribs 115 are located at the interval between the two second protruding ribs 521, so that the two first protruding ribs 115 are confined between the two second protruding ribs 521. Alternatively, the two second protruding ribs 521 are located at the interval between the two first protruding ribs 115, so that the two second protruding ribs 521 are confined between the two first protruding ribs 115. In this way, the first protruding ribs 115 and the second protruding ribs 521 also serve to guide the movement of the movable rod 50.

[0102] Optionally, the interlayer portion 114 has an opening at one end near the cup lid 14. A protrusion 1141 is provided on the inner surface of the interlayer portion 114 near the opening. One end of the cup lid 14 is rotatably connected to the cup body 11 via a spindle. The other end of the cup lid 14 is provided with a snap-fit ​​portion 141. The snap-fit ​​portion 141 can be a buckle that protrudes relative to the inner surface of the cup lid 14. When the cup lid 14 is closed on the dust outlet 112, the snap-fit ​​portion 141 extends into the interlayer portion 114 through the opening and snaps onto the protrusion 1141, thereby restricting the cup lid 14 from opening.

[0103] Please see Figures 10 to 15 The diagrams show the structure of the vacuum cleaner with the dust removal button 241 in different states.

[0104] Among them, such as Figure 11 As shown, when the dust removal button 241 is not pressed, a certain distance is maintained between the trigger end 501 and the locking part 141. This design ensures better locking reliability between the locking part 141 and the protrusion 1141, avoiding interference from the movable rod 50. This design also provides a better pressing feel for the dust removal button 241, improving the comfort of one-button opening operation.

[0105] Specifically, when the dust removal button 241 is pressed to its first stroke, the movable lever 50 moves from... Figure 11 The state shown is separated from the latching part 141, becoming as follows Figure 12 The state shown is that the button 241 is in contact with the latching part 141. During this process, the tactile feel of the dust removal button 241 changes from low pressing resistance to high pressing resistance. This change in state provides the user with a gentle pressing damping feel, thereby improving the user experience of the product.

[0106] When the dust removal button 241 is pressed to its second stroke (which is greater than the first stroke), the movable lever 50 moves from the position indicated by the pressure applied to the first stroke. Figure 12 The state of contact between the shown contact portion 141 and the contact portion becomes as follows: Figure 13 The image shows the state where the latching part 141 is pushed open. Because the latching part 141 is pushed open from the protrusion 1141 by the trigger end 501, the latching state between the cup lid 14 and the cup body 11 is released, and the cup lid 14 is released from the state of closing the dust outlet 112 (as shown in the image). Figure 10 (As shown) Switch to as Figure 14 and Figure 15 The open state is shown.

[0107] Optionally, when the dust removal button 241 is not pressed, a 1mm gap is maintained between the trigger end 501 and the locking part 141. Of course, it is understood that the gap between the trigger end 501 and the locking part 141 when the dust removal button 241 is not limited to 1mm. In other embodiments, the gap between the trigger end 501 and the locking part 141 can be adjusted as needed, for example, to 0.1mm, 5mm, or any value between 0.1mm and 5mm.

[0108] Optionally, the end of the locking part 141 is provided with a guide slope. When the cup lid 14 is closed, the guide slope cooperates with the protrusion 1141 on the cup body 11, making the locking part 141 and the protrusion 1141 engage more smoothly. This can also reduce damage to the engagement between the locking part 141 and the protrusion 1141, thus extending the life of the locking part 141.

[0109] Alternatively, to improve the smoothness of the trigger end 501 opening the latching part 141, a first inclined surface 5211 is provided at the end of the second protruding rib 521 of the side beam 52 near the trigger end 501, and a second inclined surface 522 opposite to the first inclined surface 5211 is provided on the side beam 52. In this way, the trigger end 501 of the side beam 52 has a structure that gradually narrows along the direction near the end, which makes it easier for the trigger end 501 to be inserted between the guide inclined surface of the latching part 141 and the surface of the interlayer part 114, so as to smoothly open the latching part 141.

[0110] Optionally, such as Figure 6 As shown, a first elastic element 2411 is provided between the dust removal button 241 and the main unit 20. Specifically, the first elastic element 2411 can be... Figure 7 The spring shown is elastically supported between the dust removal button 241 and the main unit 20. The elastic force of the first elastic element 2411 can drive the dust removal button 241 to reset after it is released, making it convenient to press the dust removal button 241 again.

[0111] Optionally, such as Figure 9 As shown, a second elastic element 54 is provided between the movable rod 50 and the main unit 20 or the cup body 11. The second elastic element 54 can specifically be... Figure 9 The spring is shown in the diagram. The second elastic element 54 is elastically supported between the movable rod 50 and the main unit 20 or the dust cup 10. The elastic force of the second elastic element 54 can drive the movable rod 50 to reset after the dust removal button 241 is released, making it convenient to close the cup lid 14 next time.

[0112] Optionally, combined Figure 7 and Figure 10 It can be understood that the main unit 20 is a housing, which is closed at the top and has an opening at the bottom, wherein, for example... Figure 1 As shown, a ventilation structure 213 is provided on the side wall of the housing. The ventilation structure 213 can be a grille or a porous structure on the side wall of the housing. The ventilation structure 213 is used to allow airflow to be discharged from the main unit 20. The handle 22 can be a structure formed by the mating of an upper cover 221 and a lower cover 222. The lower cover 222 is located at the upper end of the housing and can be integrally formed with the housing. The upper cover 221 covers the lower cover 222. The handle 22 spans above the battery compartment 211, and the two ends of the handle 22 serve as two connecting parts 2202 to connect to the two sides of the upper end of the housing. The middle part of the handle 22 serves as a gripping part 2201 for holding. The gripping part 2201 is provided corresponding to the battery compartment 211 and is suspended relative to the battery compartment 211. The upper ends of the housing are also covered by a first upper cover 1181 and a second upper cover 1182. A dust removal button 241 is provided on one of the connecting parts 2202 of the handle 22. The vacuum cleaner also includes a switch button 242 for controlling the vacuum cleaner to turn on and off, which is also located on the handle 22. Of course, this application is not limited to this. In other embodiments, the switch button 242 can be replaced with a gear button, or in other embodiments, the handle can be provided with both the switch button 242 and the gear button.

[0113] The lower end of the housing is connected to the dust cup 10, and the opening at the lower end of the housing is covered by the top wall 110 of the dust cup 10. A mounting base 35 protrudes from the top wall 110 of the dust cup 10 towards the main unit, and the airflow drive device is positioned corresponding to the mounting base 35. Specifically, the airflow drive device includes, for example, a motor 31 and fan blades (not shown in the figure) that can be driven by the motor 31. The main unit also includes an internal cover 32, a fixing base 33, and a sealing ring 34. The cover 32 and the mounting base 35 are mated to enclose an installation chamber. The fixing base 33, the motor 31, and the sealing ring 34 are all located within the installation chamber. The fixing base 33 is positioned between the motor 31 and the cover 32, and the sealing ring 34 is positioned between the motor 31 and the mounting base 35. Using the mounting base 35 on the top wall 110, the airflow drive device can be quickly positioned and installed, while also ensuring that the airflow drive device is positioned between the battery pack and the dust cup.

[0114] The air outlet 111 of the dust cup 10 is set corresponding to the mounting base 35. Preferably, a grille 1111 is provided at the air outlet 111 to play a role in protection and filtration.

[0115] The top beam 51 and extension arm 55 of the movable rod 50 are both located inside the housing and to the side of the cover 32 and the mounting base 35. One end of the top beam 51 extends out of the housing and passes through the handle 22, corresponding to the dust removal button 241. The other end of the top beam 51 is provided with a fixing post 531. The second elastic member 54 is fitted onto the fixing post 531. One end of the second elastic member 54 abuts against the top beam 51, and the other end abuts against the dust cup 10. One side wall of the dust cup 10 cup body 11 is provided with an internally hollow interlayer portion 114. Both the upper and lower ends of the interlayer portion 114 are open. The side beam 52 passes through the interlayer portion 114 of the dust cup 10. One end of the side beam 52 extends out of the interlayer portion 114 and connects to the extension arm 55. The other end of the side beam 52 serves as the trigger end 501 for opening the latching portion 141.

[0116] The extension arm 55 transitions between the top beam 51 and the side beam 52, and is inclined relative to both the top beam 51 and the side beam 52, so that the side beam 52 can be set as close as possible to the side wall of the dust cup 10, thereby saving the space of the interlayer 114, and realizing that the top beam 51 is correspondingly set with the dust discharge button 241 located on the inner edge of the main unit 20.

[0117] Optionally, combined Figure 8 as well as Figure 10It can be understood that the inner cylinder 12 is located inside the dust cup 10. One axial end of the inner cylinder 12 is positioned corresponding to the air outlet 111 and connected to the inner surface of the cup body 11. The other axial end of the inner cylinder 12 faces the dust discharge port 112. There is a gap distance H1 between this other axial end of the inner cylinder 12 and the cup lid 14, and this other axial end of the inner cylinder 12 is suspended relative to the cup lid 14. The inner cylinder 12 and the dust collection space 13 are connected along the part of the inner cylinder 12 that is suspended relative to the cup lid 14. Here, "suspended" can be understood as meaning that there is no support between this other axial end of the inner cylinder 12 and the cup lid 14. By connecting the inner cylinder 12 and the dust collection space 13 along the suspended portion of the inner cylinder 12 relative to the cup lid 14, the swirling air within the inner cylinder 12 can evenly throw dust circumferentially into the dust collection space 13 outside the inner cylinder 12. This results in higher cyclone separation efficiency and allows dust to accumulate more evenly circumferentially within the integrated space, making fuller use of the dust cup 10's volume and achieving a larger dust holding capacity. Furthermore, the spaced structure between the inner cylinder 12 and the cup lid 14 prevents interference between them, making it easier and less strenuous for the cup lid 14 to close onto the dust discharge port 112.

[0118] Optionally, the surface of the inner cylinder 12, except for the air inlet, is designed without any notches. This simplifies the structure of the inner cylinder 12, reduces costs, and allows for better control over the molding quality of the inner cylinder 12, thereby ensuring the swirling dynamics within the inner cylinder 12. Of course, this application is not limited to this. In other embodiments, one or more notches may be provided on the side wall of the inner cylinder 12. Specifically, the notches penetrate the side wall of the inner cylinder 12 along the wall thickness direction, and the notches are used to allow dust inside the inner cylinder to be discharged into the dust collection space.

[0119] Optionally, such as Figure 7 As shown, the vacuum cleaner also includes a HEPA filter structure 70, which is detachably disposed in the inner cylinder 12 for filtering dust. Further optionally, the diameter of the HEPA filter structure 70 is smaller than the inner diameter of the inner cylinder 12, and the HEPA filter structure 70 is located within the inner cylinder 12 and radially spaced from it, thus forming an annular gap between the HEPA filter structure 70 and the inner cylinder 12 to allow airflow to undergo cyclonic separation along this gap.

[0120] Optionally, such as Figure 8 As shown, a connecting structure is provided on the inner surface of the dust cup 10 around the air outlet 111. One end of the HEPA structure 70 is connected to this connecting structure, so that the HEPA structure will not fall off when the cup lid is opened with one click, making it more convenient to use. The other end of the HEPA structure 70 is positioned towards the cup lid 14 and is spaced apart from the cup lid 14. This way, when the cup lid 14 is closed, the HEPA structure 70 will not abut against the cup lid 14, achieving a better sealing effect.

[0121] Optionally, the connection structure may include a rotating slot 117, and the HEPA structure 70 may also be provided with a protruding tongue 71, which is rotatably connected to a rotating buckle, thereby allowing the HEPA structure 70 to be detachably installed on the inner top surface of the dust cup 10. This facilitates repeated disassembly and assembly of the HEPA structure 70 by the user, making it convenient for daily cleaning or replacement of the HEPA structure 70. Of course, this application is not limited to this; in other embodiments, the HEPA structure 70 may also be connected to the inner top surface of the dust cup 10 via an elastic snap-fit ​​structure.

[0122] Optionally, such as Figure 14 As shown, one end of the side wall of the cup body 11 forms a dust discharge port 112. In this way, when the cup lid is opened, the dust inside the cup body 11 can be discharged along the side wall of the dust cup 10 to the dust discharge port, avoiding leaving any dead corners and making daily cleaning of the product more convenient.

[0123] In the vacuum cleaner of the embodiment, when the airflow drive device is working, the dust cup 10 draws airflow and dust into the inner cylinder 12 of the dust cup 10 along the hose 60 for swirling. During the swirling process, the dust separated by centrifugal force enters the dust collection space 13 on the outer periphery of the inner cylinder 12 along the gap between the inner cylinder 12 and the cup cover 14 for storage. The airflow is filtered by the HEPA structure 70 and then enters the main unit 20 along the air outlet 111, and is finally discharged along the ventilation structure 213 of the main unit 20. In this embodiment of the vacuum cleaner, because there is a gap between the end of the inner cylinder 12 facing the dust outlet 112 and the cup lid 14, the swirling air inside the inner cylinder 12 can be concentrated and maintained at a position closer to the air outlet 111. The centrifugal force of the cyclone separation is greater, which can more efficiently throw the dust in the airflow into the dust collection space 13. The cyclone separation effect is better. In this way, the dust will not keep rotating in the inner cylinder 12, the power loss of the airflow is reduced, the vacuum cleaner has higher dust collection efficiency, and because the dust is discharged more efficiently, the problem of dust clogging the dust cup air outlet 111 is also better avoided.

[0124] Example 2:

[0125] like Figure 16 and Figure 17 As shown, this embodiment provides a vacuum cleaner, including a main unit 20, a dust cup 10, and a hose 60.

[0126] The difference between this embodiment and the first embodiment described above includes: this vacuum cleaner also includes a cyclone structure 80.

[0127] The cyclone structure 80 is located inside the dust cup 10 and at the end of the inner cylinder 12 facing the cup cover 14. When the cup cover 14 is closed on the dust discharge port 112, the cyclone structure 80 is in contact with or has a gap between it and the cup cover 14. The inner cylinder 12 and the dust collection space 13 are connected along the cyclone structure 80.

[0128] In more detail, combined Figure 16 and Figure 17 It is understood that the top of the cyclone structure 80 has an opening, and the top opening of the cyclone structure 80 is connected to the bottom of the inner cylinder 12. The bottom of the cyclone structure 80 is provided with a spirally extending air guide surface, which is arranged around a central cylinder. The top of the central cylinder is set in a conical shape. The outer periphery of the air guide surface is provided with a peripheral side surface, which is partially open to form a side opening 81. The inner cylinder 12 communicates with the dust collection space 13 through the side opening 81.

[0129] By setting up the cyclone structure 80, the airflow entering the inner cylinder 12 is guided by the air guide surface of the cyclone structure 80, thereby forming a vortex more efficiently and with lower resistance. This results in higher cyclone separation efficiency within the inner cylinder 12. During cyclone separation within the inner cylinder 12, the dust separated by centrifugal force enters the dust collection space 13 on the outer periphery of the inner cylinder 12 through the side opening 81 of the cyclone structure 80 for storage, while the airflow enters the main unit 20 through the air outlet 111 and is finally discharged along the ventilation structure 213 of the main unit 20. In this embodiment, the vacuum cleaner, by setting up the cyclone structure 80, improves the cyclone separation effect within the inner cylinder 12, thereby enabling the vacuum cleaner to have good suction power.
