Description

Technical Field

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

[0002] Existing portable vacuum cleaners, such as car vacuum cleaners and handheld vacuum cleaners, sacrifice some functionality to simplify the product structure and achieve miniaturization and portability in pursuit of a simple and compact appearance. A common approach is to recess one side of the dust cup to make room for the battery pack. This design, placing the battery pack on the side of the dust cup, not only reduces the volume of the dust cup, decreasing its capacity, but also makes the vacuum cleaner prone to instability. Utility Model Content

[0003] One objective of this invention is to provide a vacuum cleaner with good center of gravity stability, a larger dust cup volume, and stronger and more stable suction power.

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

[0005] One aspect of the present invention provides a vacuum cleaner, comprising: a main unit, the main unit including a housing, a battery pack disposed on the housing, and an airflow driving device disposed within the housing; a dust cup, the upper end of the dust cup being connected to the lower end of the housing, the horizontal cross-sectional shape of the dust cup being the same as the horizontal cross-sectional shape of the housing, and the airflow driving device being located at the interval between the battery pack and the dust cup.

[0006] According to some technical solutions of this application, the dust cup is provided with an inner cylinder that protrudes downward relative to the inner top surface of the dust cup. The dust cup is provided with an air outlet corresponding to the upper end of the inner cylinder. The air outlet is connected to the airflow driving device and the inner cylinder respectively. At least a portion of the inner cylinder is spaced apart from the side wall of the dust cup along the circumferential direction to define a dust collection space located between the inner cylinder and the side wall of the dust cup. The dust collection space is connected to the inner cylinder. The inner cylinder is provided with an air inlet for tangential air intake. The dust cup is provided with an air intake channel connected to the air inlet.

[0007] According to some technical solutions of this application, the lower end of the inner cylinder is suspended, and the inner cylinder and the dust collection space are connected along the suspended part of the inner cylinder; or the lower end of the inner cylinder is provided with a cyclone structure, the lower end of the cyclone structure is suspended or supported, and the inner cylinder and the dust collection space are connected along the cyclone structure.

[0008] According to some technical solutions of this application, one or more dust discharge notches are provided on the side wall of the inner cylinder, and the inner cylinder and the dust collection space are connected along the dust discharge notches; the dust discharge notches are located near the lower end of the inner cylinder.

[0009] According to some technical solutions of this application, a battery slot is formed by a recess on a portion of the upper surface of the housing, and the battery pack is detachably slidably connected to the battery slot.

[0010] According to some technical solutions of this application, a handle is provided at the upper end of the housing, and the handle is arched relative to the upper surface of the housing, so that a clearance space is formed between the handle and the housing, and the battery pack is disposed on the side of the housing close to the clearance space.

[0011] According to some technical solutions of this application, the lower end of the dust cup is provided with a dust discharge port and a cup lid. One end of the cup lid is rotatably connected to the dust cup, and the other end of the cup lid is provided with a snap-fit ​​part, which is detachably snapped into the dust cup. The handle is provided with a dust discharge button, and the vacuum cleaner also includes a transmission structure. The transmission structure is disposed between the dust discharge button and the snap-fit ​​part. The transmission structure is used to act on the snap-fit ​​part under the drive of the dust discharge button, so that the snap-fit ​​part releases the dust cup.

[0012] According to some technical solutions of this application, the transmission structure includes a movable rod, which is movably disposed on the housing and the dust cup. One end of the movable rod is connected to the dust discharge button, and the other end of the movable rod is disposed corresponding to the locking part. The dust discharge button can be pressed to drive the movable rod to move relative to the housing and the dust cup, so that the movable rod drives the locking part to release the dust cup.

[0013] According to some technical solutions of this application, the lower end of the side wall of the housing is correspondingly and smoothly transitioned to the upper end of the side wall of the dust cup. The housing has an opening at the lower end, and the upper end of the dust cup has a top wall. The top wall blocks the opening at the lower end of the housing. A mounting seat is provided on the side of the top wall facing the housing, and the airflow driving device is provided corresponding to the mounting seat.

[0014] According to some technical solutions of this application, a flexible hose extends from the dust cup and communicates with the air inlet. A hose fixing member is provided on the side wall of the dust cup or the side wall of the housing. The hose is wrapped around the outer periphery of the dust cup and / or the housing and is detachably connected to the hose fixing member.

[0015] The vacuum cleaner of this application has its main unit housing and dust cup arranged vertically, with the battery pack mounted on the main unit housing. The airflow drive device inside the housing is located between the battery pack and the dust cup. This arrangement ensures that when the vacuum cleaner is placed, the dust cup, airflow drive device, and battery pack are roughly aligned vertically from bottom to top, making the vacuum cleaner less prone to tipping over and providing greater stability. Furthermore, by matching the horizontal cross-sectional shape of the dust cup to that of the housing, the stability of the dust cup's support for the main unit is guaranteed. This allows for a larger dust cup volume without increasing the overall horizontal dimensions of the vacuum cleaner, thus ensuring sufficient capacity. This reduces the need for frequent emptying and provides ample space within the dust cup for effective dust and gas separation, enabling the vacuum cleaner to maintain stronger and more stable suction, thereby improving its cleaning efficiency.

Detailed Implementation

[0039] Although the present invention can be readily embodied in various forms of implementation, only some specific embodiments are shown in the accompanying drawings and will be described in detail in this specification. It is also understood that this specification should be regarded as an exemplary description of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0040] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0041] In the embodiments shown in the accompanying drawings, directional indications (such as up, down, etc.) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the description of the positions of these elements changes, these directional indications also change accordingly.

[0042] 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. The same reference numerals in the drawings denote the same or similar parts, and therefore repeated descriptions of them will be omitted.

[0043] This utility model provides a vacuum cleaner in some embodiments. It can be understood that a vacuum cleaner is a device that uses airflow to drive a mechanism, creating negative air pressure inside the vacuum cleaner, and then uses this negative air pressure to suck up dust and debris.

[0044] Specifically, the vacuum cleaner includes a dust cup 10 and a main unit.

[0045] The main unit includes a housing 20, a battery pack 40 disposed on the housing 20, and an airflow drive device disposed inside the housing 20; the upper end of the dust cup 10 is connected to the lower end of the housing 20, the horizontal cross-sectional shape of the dust cup 10 is the same as the horizontal cross-sectional shape of the housing 20, and the airflow drive device is located at the interval between the battery pack 40 and the dust cup 10.

[0046] The vacuum cleaner described in this application, such as Figure 10 As shown, the main unit's housing 20 and dust cup 10 are arranged vertically, with the battery pack 40 mounted on the housing 20. The airflow drive device within the housing 20 is positioned between the battery pack 40 and the dust cup 10. This arrangement ensures that when the vacuum cleaner is placed horizontally, the dust cup 10, airflow drive device, and battery pack 40 are roughly aligned vertically from bottom to top, making the vacuum cleaner less prone to tipping over and improving its stability. Even when the vacuum cleaner is placed horizontally, i.e., when the dust cup 10, main unit, and battery pack 40 are arranged from left to right or right to left, tipping over is also less likely. By setting the horizontal cross-sectional shape of the dust cup 10 to be the same as that of the housing 20, the stability of the dust cup 10 in supporting the main unit is ensured. At the same time, the volume of the dust cup 10 can be maximized without increasing the overall horizontal size of the vacuum cleaner to maintain a miniaturized appearance. This ensures the capacity of the dust cup 10, so that users do not need to empty the dust frequently. The dust cup 10 also has more space to ensure the separation of dust and gas, so that the vacuum cleaner can maintain a greater and more stable suction power to improve the vacuum cleaner's dust collection efficiency.

[0047] Optionally, the vacuum cleaner of this application can be a portable vacuum cleaner, wherein the vacuum cleaner includes a battery pack 40, which powers the vacuum cleaner. The battery pack 40 can be a rechargeable battery or a battery that is directly connected to a power outlet. Preferably, using a rechargeable battery allows the vacuum cleaner to be used without a cord, thus having better portability. It also makes the vacuum cleaner safer when used by hand, reducing the risk of electric shock. Furthermore, by placing the battery pack 40 on the housing 20 of the main unit, the battery pack 40 is not occupied by the dust cup 10, achieving product miniaturization while maximizing the volume of the dust cup 10. The dust cup 10, airflow drive device, and battery pack 40 are arranged correspondingly from bottom to top, making the vacuum cleaner more stable and less prone to tipping over when placed down, making it more suitable for scenarios where portable vacuum cleaners are used and placed down at will.

[0048] Of course, the vacuum cleaner of this application is not limited to a portable vacuum cleaner. It is understood that the structure of the aforementioned vacuum cleaner can also be applied to vacuum cleaners of various types, such as canister vacuum cleaners, upright vacuum cleaners, robotic vacuum cleaners, and floor scrubbers, without conflict. Thus, this vacuum cleaner can also be selected as any one of canister vacuum cleaners, upright vacuum cleaners, robotic vacuum cleaners, and floor scrubbers.

[0049] The following will be combined with the appendix Figures 1 to 19 The vacuum cleaner of this application will be specifically described through several embodiments.

[0050] Example 1:

[0051] 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.

[0052] This vacuum cleaner may include a dust cup 10 and a main unit.

[0053] The main unit includes a housing 20, a battery pack 40, and an airflow drive device.

[0054] The battery pack 40 is used to power the vacuum cleaner and is mounted on the housing 20.

[0055] An airflow drive device, as the name suggests, is a device or component that can drive airflow. Specifically, it can be a device 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 disposed within the housing 20.

[0056] The dust cup 10 is connected to the main unit. Specifically, the upper end of the dust cup 10 is connected to the lower end of the housing 20 of the main unit, so that the dust cup 10 and the main unit are arranged in an upper-lower position with the main unit on top and the dust cup 10 on the bottom.

[0057] The airflow drive device is located in the gap between the battery pack 40 and the dust cup 10. In this way, when the vacuum cleaner is placed, the dust cup 10, the airflow drive device, and the battery pack 40 are roughly in the same vertical direction from bottom to top. Compared with the structure in which the battery pack 40 is located on one side of the outer circumference of the dust cup 10, this structure is less prone to instability because the center of gravity of the dust cup 10, the airflow drive device, and the battery pack 40 are roughly in the same vertical direction. It is more stable when placed and more suitable for portable use scenarios where it can be picked up and put down at any time.

[0058] The horizontal cross-sectional shape of the dust cup 10 is the same as that of the housing 20. This ensures that the dust cup 10 and the housing 20 of the main unit have roughly the same dimensions in all directions on the same horizontal plane. Without increasing the overall horizontal dimensions of the vacuum cleaner to maintain a compact appearance, the dust cup 10 can have the largest possible volume, thus ensuring its capacity. This reduces the need for frequent emptying of dust, and the dust cup 10 also provides ample space 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.

[0059] Optionally, the housing 20 of the main unit can be configured as follows: Figure 1 and Figure 2 As shown in the diagram, the dust cup 10 is also designed in a similar quadrilateral prism shape. Figure 1 and Figure 2 As shown in the diagram, the horizontal cross-sectional shape of the housing 20 and the dust cup 10 are essentially the same, both being quadrilateral-like shapes of similar size. The lower end of the housing 20 connects with the upper end of the dust cup 10, thus the housing 20 and the dust cup 10 together form a vacuum cleaner body with a quadrilateral prism shape. This results in a more regular product appearance, more stable support for the main unit from the dust cup 10, and a larger volume of the dust cup 10 in the horizontal direction.

[0060] Of course, in other embodiments, the shape of the host housing 20 and the dust cup 10 can also be set as cylindrical, elliptical cylindrical, etc., and is not limited to the similar quadrilateral prism shape listed in this embodiment.

[0061] Optionally, such as Figure 1 and Figure 2 As shown, the lower end of the side wall of the housing 20 corresponds to the upper end of the side wall of the dust cup 10 and transitions smoothly. This makes the outer surface of the product more continuous, easier to store, and the surface of the product less likely to accumulate dirt, making it easier to clean.

[0062] Optionally, the dust cup 10 and the housing 20 of the main unit can be fixedly connected. For example, the dust cup 10 can be fixed to the housing 20 of the main unit by screws. Alternatively, in other embodiments, the dust cup 10 and the housing 20 of the main unit can be connected in a way that facilitates disassembly, such as by snap-fit.

[0063] 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.

[0064] like Figure 3 and Figure 4 As shown, the battery pack 40 is located on the side of the main unit's housing 20 opposite to the dust cup 10. That is, the battery pack 40 and the dust cup 10 are located at opposite ends of the main unit's housing 20, which makes it easier for the airflow drive device inside the main unit's housing 20 to stay at the interval between the battery pack 40 and the dust cup 10. This makes the vacuum cleaner's center of gravity more stable, makes it easier to use the vacuum cleaner by hand, and makes the vacuum cleaner more stable and less likely to tip over when placed.

[0065] 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 is shown.

[0066] The upper surface of the main unit's housing 20 is recessed to form a battery slot 211, 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 two opposite sides of the battery pack 40, and slide grooves 2111 are provided on two 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.

[0067] Optionally, a circuit board is also provided inside the housing 20 of the main unit. The battery pack 40 and the circuit board 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. 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.

[0068] Optionally, such as Figures 1 to 4 As shown, a handle 22 is provided at the upper end of the housing 20 of the main unit, which makes it convenient for users to hold and use the vacuum cleaner by hand.

[0069] For example, the handle 22 is located on the side of the main unit's housing 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, the main unit, the battery pack 40, and the at least part of the handle 22 are arranged approximately in sequence, and the center of gravity of the handle 22, the dust cup 10, the main unit, 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.

[0070] In detail, such as Figures 1 to 4 As shown, the handle 22 is arched at the end face (i.e., the upper surface of the housing 20) of the main unit away from the dust cup 10. This arched design creates a clearance space 23 between the main unit and the handle 22. The battery pack 40 is located on the side of the main unit closest to this 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 storage while also achieving a miniaturized product design. Furthermore, the sequential arrangement of the handle 22, battery pack 40, main unit, and dust cup 10 ensures that the center of gravity of the handle 22, battery pack 40, main unit, and dust cup 10 are aligned vertically, making it easier for the user to hold the vacuum cleaner.

[0071] More in detail, such as Figure 5As shown, a battery slot 211 is recessed on the side of the main unit 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 battery slot 211 is formed by the recess on the side of the main unit near the clearance space 23. Thus, the battery slot 211 faces the clearance space 23. When the battery pack 40 is located in the battery slot 211, it can dissipate heat towards the clearance space 23, preventing the battery pack 40 from becoming too hot to the touch.

[0072] 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.

[0073] Please see Figure 6 , Figure 6 The cross-sectional structure of the vacuum cleaner in this embodiment is shown.

[0074] Please see Figure 7 , Figure 7 The exploded structure of the vacuum cleaner in this embodiment is shown.

[0075] Please see Figure 8 , Figure 8 The three-dimensional structure of the dust cup 10 in this embodiment is shown.

[0076] Combination Figure 6 and Figure 8 As shown, the lower end of the dust cup 10 is provided with a dust discharge port 112 and a cup lid 14. The cup lid 14 is closable and can be used to cover or open the dust discharge port 112. By setting the dust discharge port 112 at the lower end of the dust cup 10, when emptying the dust, the user can hold the handle 22 at the top of the main unit to lift the vacuum cleaner, and then open the cup lid 14 at the lower end of the dust cup 10. The dust in the dust cup 10 can then be discharged directly through the dust discharge port 112 at the lower end of the dust cup 10 under the action of gravity, without the need for the user to flip the dust cup 10 to empty the dust, making it more convenient to use.

[0077] like Figure 6 As shown, the dust cup 10 specifically includes a side wall, a top wall 11 located at the upper end of the side wall of the dust cup 10, and a dust discharge port 112 located at the lower end of the side wall of the dust cup 10. The housing 20 of the main unit has an opening at the lower end. When the lower end of the side wall of the housing 20 of the main unit is connected to the upper end of the side wall of the dust cup 10, the top wall 11 of the dust cup 10 seals the opening at the lower end of the housing 20. In this way, the bottom wall of the housing 20 of the main unit is omitted, and when the housing 20 of the main unit is connected to the dust cup 10, the opening at the lower end of the housing 20 is sealed at the same time, which simplifies both the product structure and the product assembly process.

[0078] The dust cup 10 has an inner cylinder 12 inside, which protrudes downward relative to the lower surface of the top wall 11 of the dust cup 10. The top wall 11 of the dust cup 10 has an air outlet 111 corresponding to the upper end of the inner cylinder 12. The air outlet 111 is connected to the airflow driving device and the inner cylinder 12 respectively. At least a portion of the inner cylinder 12 is spaced apart from the side wall of the dust cup 10 along the circumferential direction to define a dust collection space 13 between the inner cylinder 12 and the side wall of the dust cup 10. The dust collection space 13 is connected to the inner cylinder 12. The inner cylinder 12 has an air inlet 121 for tangential air intake. The dust cup 10 has an air intake channel 113 connected to the air inlet 121.

[0079] When the airflow drive device inside the main unit 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 13 outside the inner cylinder 12 by centrifugal force for collection, while the airflow is drawn into the main unit by the airflow drive device along the air outlet 111.

[0080] By incorporating an inner cylinder 12 within the dust cup 10 to create swirling airflow, compared to a dust cup with only a filter, the centrifugal force during the swirling process efficiently separates the airflow from the dust. This avoids the problem of dust continuously swirling within the dust cup 10, which leads to decreasing airflow and suction power. It also reduces the risk of the dust cup 10's outlet 111 being clogged by larger dust particles. This makes the vacuum cleaner more suitable for scenarios involving larger dust particles compared to existing vacuum cleaners, broadening its applicability. Furthermore, the structure of the inner cylinder 12 within the dust cup 10 is not only simple in structure, easy to manufacture, low in cost, lightweight, and easy to clean, but most importantly, the inner cylinder 12 does not excessively occupy the effective volume of the dust cup 10. This achieves a balance between product miniaturization, vacuum cleaner suction power, and the effective volume requirements of the dust cup 10.

[0081] 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.

[0082] Optionally, the inner cylinder 12 can be configured as follows: Figure 8The inner cylinder 12 is cylindrical in shape. This design reduces resistance during the airflow and dust swirling process within the inner cylinder 12, resulting in higher efficiency in separating dust and airflow. However, this application is not limited to this; in other embodiments, the inner cylinder 12 can also be configured as an elliptical cylinder, a conical cylinder, etc.

[0083] Optionally, combined Figure 3 , Figure 6 and Figure 8 As 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.

[0084] Alternatively, the air inlet channel 113, the inner cylinder 12, and the dust cup 10 can be integrally formed.

[0085] Optionally, combined Figure 1 , Figure 2 and Figure 6 It is understood that a flexible hose 60 extends from the mounting port 201 on the side wall of the dust cup 10, and the flexible hose 60 is connected to the air inlet 121 on the inner cylinder 12. A flexible hose fixing member 212 is provided on the outer peripheral surface of the dust cup 10, and the flexible hose 60 is wrapped around the outer peripheral side of the dust cup 10 in the circumferential direction. The flexible hose 60 is detachably connected to the flexible hose fixing member 212, so that the flexible hose 60 is stably and reliably wrapped around the dust cup 10, which facilitates the storage of the product.

[0086] 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, the hose 60 can be wrapped around the dust cup 10 or the outer periphery of the host, and the end of the hose 60 away from the installation port 201 can be detachably connected to the hose fixing member 212 on the surface of the host.

[0087] 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), or a Velcro strap can be provided between the dust cup 10 or the main unit and the hose 60, allowing the hose 60 to adhere to the surface of the dust cup 10 or the main unit.

[0088] Optionally, such as Figure 8As shown, the inner cylinder 12 is radially spaced from the side wall of the dust cup 10 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 dust cup 10 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, since the dust cup 10 is a quadrilateral prism and the inner cylinder 12 is cylindrical, and the inner cylinder 12 and the side wall of the dust cup 10 are radially spaced apart, the volume of the dust collection space 13 between the inner cylinder 12 and the side wall of the dust cup 10 is larger.

[0090] Optionally, one end of the cup lid 14 is rotatably connected to the dust cup 10, and the other end of the cup lid 14 is provided with a locking part 141, which is detachably locked to the dust cup 10. 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 dust cup 10. 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 cup 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, and on the side of the handle away from the center line. This allows the user to press the dust removal button with their thumb while holding the handle with one hand, making it more convenient for the user to press the dust removal button 241 while holding the handle, thus achieving one-handed one-button operation.

[0092] Please see Figure 9 , Figure 9 The exploded view of the dust removal button 241, handle 22, and movable lever 50 is shown.

[0093] like Figure 9As shown, the transmission structure includes a movable rod 50, which is movably mounted on the housing 20 of the main unit and the dust cup 10. 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 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 and the dust cup 10, thereby driving the locking part 141 to release the locking part 141 from the dust cup 10. 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 one-handed dust removal operations.

[0094] 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 tractively 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 dust cup 10. 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, 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.

[0095] 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 respectively lock into the dust cup 10. 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 dust cup 10. The two locking parts 141 spaced apart on the cup lid 14, which lock into the dust cup 10, enable a more reliable connection between the cup lid 14 and the dust cup 10, and the cup lid 14 is less prone to shaking when locked into the dust cup 10. 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 dust cup 10, enabling one-button opening control. This also saves on the size and weight of the movable lever 50, making the one-button opening operation more effortless 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.

[0096] Alternatively, the movable rod 50 may be a one-piece molded component.

[0097] Alternatively, the top beam 51 and the extension arm 55 are movably disposed within the housing 20 of the main unit, and the side beam 52 is movably disposed within the dust cup 10. 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, and only a small amount of space needs to be allocated in the dust cup 10 to accommodate the side beam 52. This 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.

[0098] Furthermore, optionally, combined with Figure 8 and Figure 9 It is understood that at least one side wall of the dust cup 10 is constructed with a sandwich section 114, which is hollowly disposed in the sandwich section 114, and the side beam 52 is movably inserted in the sandwich section 114.

[0099] 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.

[0100] 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.

[0101] 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 dust cup 10 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 to the dust discharge port 112, the snap-fit ​​portion 141 extends into the interlayer portion 114 through the opening of the interlayer portion 114 and snaps onto the protrusion 1141, thereby restricting the cup lid 14 from opening.

[0102] Please see Figures 10 to 15 The diagrams show the structure of the vacuum cleaner with the dust removal button 241 in different states.

[0103] 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.

[0104] 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.

[0105] 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 dust cup 10 is released, and the cup lid 14 is removed 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.

[0106] 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.

[0107] Optionally, the end of the snap-fit ​​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 dust cup 10, making the snap-fit ​​part 141 and the protrusion 1141 engage more smoothly. This can also reduce damage to the engagement between the snap-fit ​​part 141 and the protrusion 1141, thus extending the service life of the snap-fit ​​part 141.

[0108] 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.

[0109] Optionally, such as Figure 6 As shown, a first elastic element 2411 is provided between the dust removal button 241 and the main unit. 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 by the first elastic element 2411. 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.

[0110] Optionally, such as Figure 9 As shown, a second elastic element 54 is provided between the movable rod 50 and the main unit or dust cup 10. Specifically, the second elastic element 54 can 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 or 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.

[0111] In more detail, combined Figure 7 and Figure 10 It is understandable that the upper part of the main unit's casing 20 is closed, while the lower part has an opening, such as... Figure 1 As shown, a ventilation structure 213 is provided on the side wall of the housing 20. The ventilation structure 213 can be a grille or a porous structure on the side wall of the housing 20. The ventilation structure 213 is used to allow airflow to be discharged from the housing 20 of the main unit.

[0112] 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 20 and can be integrally formed with the housing 20. The upper cover 221 is fitted onto the lower cover 222. The handle 22 spans across the battery compartment 211, and the two ends of the handle 22 serve as two connecting parts 2202 to be connected to the two sides of the upper end of the housing 20. 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 20 are also covered by a first upper cover 1181 and a second upper cover 1182.

[0113] A dust extraction button 241 is located on one of the connecting portions 2202 of the handle 22. The vacuum cleaner also includes a switch button 242 for controlling the vacuum cleaner's on / off operation, which is also located on the handle 22. Of course, this application is not limited to this; in other embodiments, the switch button 242 may be replaced with a gear selector button, or in other embodiments, the handle may be provided with both a switch button 242 and a gear selector button.

[0114] The lower end of the housing 20 is connected to the dust cup 10, and the opening at the lower end of the housing 20 is covered by the top wall 11 of the dust cup 10. A mounting seat protrudes from the top wall 11 of the dust cup 10 towards the housing 20, and the airflow drive device is positioned corresponding to the mounting seat. 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 a cover 32, a fixing seat 33, and a sealing ring 34 housed within the housing 20. The cover 32 and the mounting seat 35 are mated to enclose an installation chamber. The fixing seat 33, the motor 31, and the sealing ring 34 are all located within the installation chamber. The fixing seat 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 seat 35. Using the mounting seat on the top wall 11, 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.

[0115] 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.

[0116] The top beam 51 and extension arm 55 of the movable rod 50 are both located inside the housing 20 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 20 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 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. When the dust removal button 241 is pressed, the dust removal button 241 abuts against the top beam 51 to drive the movable rod 50 to move downward together until the trigger end 501 of the movable rod 50 pushes open the locking part 141, so that the locking part 141 releases the dust cup 10, thereby realizing one-button opening control.

[0117] Meanwhile, 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. In this way, the entire movable rod 50 is roughly concentrated on the side of the dust cup 10 and the main unit, so as not to affect the volume of the dust cup 10 or the arrangement of components inside the main unit.

[0118] 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 provided corresponding to the air outlet 111 and connected to the inner surface of the dust cup 10. The other axial end of the inner cylinder 12 is provided towards the cup cover 14, and at least a portion of the edge of the other axial end of the inner cylinder 12 has a gap distance H1 between it and the cup cover 14.

[0119] More in detail, such as Figure 8 and Figure 10 As shown, one axial end of the inner cylinder 12 is positioned corresponding to the air outlet 111 and connected to the inner surface of the dust cup 10. The other axial end of the inner cylinder 12 faces the cup lid 14, and at least a portion of the edge of this other axial end of the inner cylinder 12 is spaced apart from the cup lid 14 by a distance H1. This other axial end of the inner cylinder 12 is suspended, and the inner cylinder 12 communicates with the dust collection space 13 along the suspended portion of the inner cylinder 12. Thus, the inner cylinder 12 and the dust collection space 13 on its outer periphery are connected through the gap between the inner cylinder 12 and the cup lid 14, facilitating the throwing of dust into the dust collection space 13 around the inner cylinder 12 during the swirling process. Furthermore, the structure of the inner cylinder 12 and the cup lid 14 being spaced apart and suspended relative to the cup lid 14 prevents interference between them, making it easier and less strenuous for the cup lid 14 to close onto the dust outlet 112.

[0120] 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 cyclone separation along this gap.

[0121] Optionally, such as Figure 8 As shown, a rotating slot 117 is provided on the inner surface of the dust cup 10 around the air outlet 111. The HEPA structure 70 also has 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. Of course, this application is not limited to this; in other embodiments, the HEPA structure 70 can also be connected to the inner top surface of the dust cup 10 via an elastic snap-fit ​​structure.

[0122] In the vacuum cleaner of this 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, where they swirl. 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 through the gap between the inner cylinder 12 and the cup lid 14 for storage. The airflow, after being filtered by the HEPA structure 70, enters the main unit through the air outlet 111 and is finally discharged through the ventilation structure 213 of the main unit. The vacuum cleaner of this embodiment can achieve miniaturization. At the same time, through the positional design of the battery pack, dust cup, and airflow drive device, the vacuum cleaner has good center of gravity stability, as well as a larger dust cup volume and suction power. Furthermore, the inner cylinder of the dust cup further enhances the cyclone separation function of the airflow and dust in the dust cup, thereby further improving the suction power of the vacuum cleaner.

[0123] Example 2:

[0124] This embodiment provides a vacuum cleaner, including a main unit, a dust cup 10, and a hose 60.

[0125] like Figure 16 As shown, the difference between this embodiment and the first embodiment above includes: in this embodiment, one or more dust discharge notches 122 are provided on the side wall of the inner cylinder 12 of the dust cup 10, and the inner cylinder 12 and the dust collection space 13 are connected along the dust discharge notches 122.

[0126] In this way, when cyclone separation occurs inside 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 dust discharge opening 122 for storage, while the airflow enters the main unit through the air outlet 111 and is finally discharged along the ventilation structure 213 of the main unit. The vacuum cleaner of this embodiment can achieve miniaturization while taking into account the volume of the dust cup 10 and the cyclone separation function of the airflow and dust in the dust cup 10, so that the vacuum cleaner can have good suction power.

[0127] Optionally, the dust discharge notch 122 is located at one end of the inner cylinder 12 near the cup lid 14. This ensures high cyclone separation efficiency while simultaneously maintaining the structural strength of the inner cylinder 12.

[0128] Of course, this application is not limited to this. In other embodiments, a dust discharge notch 122 may be provided at the middle position between the two axial ends of the inner cylinder 12, and / or a dust discharge notch 122 may be provided at the end of the inner cylinder 12 away from the cup lid 14.

[0129] Optionally, such as Figure 17 As shown, when the cup lid 14 is closed on the dust discharge port 112, one axial end of the inner cylinder 12 corresponds to the cup lid 14 of the dust cup 10 and is in contact with the cup lid 14.

[0130] Of course, this application is not limited to this. In other embodiments, when the cup lid 14 is closed on the dust discharge port 112, one axial end of the inner cylinder 12 corresponds to the cup lid 14 of the dust cup 10 and has a distance between them.

[0131] The main unit, hose 60, dust cup 10 lid 14, and movable rod 50 between lid 14 and dust discharge button 241 in this embodiment can be understood by referring to the content of the above embodiment without conflict, and will not be repeated here.

[0132] Example 3:

[0133] like Figure 18 and Figure 19 As shown, this embodiment provides a vacuum cleaner, including a main unit, a dust cup 10, and a hose 60.

[0134] The difference between this embodiment and the first embodiment described above is that this vacuum cleaner also includes a cyclone structure 80.

[0135] 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.

[0136] In more detail, combined Figure 18 and Figure 19 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.

[0137] 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 low 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 through the air outlet 111 and is finally discharged along the ventilation structure 213 of the main unit. The vacuum cleaner of this embodiment can achieve miniaturization while taking into account the volume of the dust cup 10 and the cyclone separation function of the airflow and dust within the dust cup 10, thus enabling the vacuum cleaner to have good suction power.

[0138] The main unit, hose 60, dust cup 10 lid 14, and movable rod 50 between lid 14 and dust discharge button 241 in this embodiment can be understood by referring to the content of the above embodiment without conflict, and will not be repeated here.

[0139] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
