Description

Technical Field

[0001] This disclosure relates to a dust collection device and a stick vacuum cleaner. Background Technology

[0002] Stick vacuum cleaners are suitable for cleaning hard floor surfaces such as tile and hardwood. After cleaning hard floor surfaces with a stick vacuum cleaner, users typically place it on a docking station to transfer the dirt inside the vacuum cleaner to the docking station.

[0003] Current stick vacuum cleaners typically employ a side-intake design. This means that air containing dust and other dirt enters the dust cup through the suction tube, with an air inlet located on the side of the dust cup. However, as suction power increases, there's a risk of particulate matter accumulating at the dust cup's air inlet after a period of use, eventually causing blockage and negatively impacting the user experience.

[0004] The current solution involves installing a baffle at the air inlet, positioned between the outer side of the separator and the inner wall of the dust cup, to guide air containing dirt particles smoothly into the dust cup for filtration. However, the baffle is a structural component, occupying space within the overall separator design and significantly increasing the radial dimension of the dust cup, resulting in a larger diameter. A larger dust cup obviously hinders the ease of handheld operation for users.

[0005] Existing technology CN119769937A discloses a cyclone separator assembly, dust collection device, cleaning equipment, and cleaning system. In this cyclone separator assembly, no separate design space is provided for the guide vane between the inner wall of the dust cup and the outer wall of the separator. Instead, the guide vane is positioned by occupying a portion of the radial space of the separator inward. This guide vane encroaches on a portion of the first separator (filter screen) and occupies the arrangement space of the second separator (cyclone cone) within the filter screen. This design of the guide vane affects the normal arrangement of the cyclone cones, forcing them to face away from the guide vane. Consequently, the second separator (cyclone cone) cannot be concentrically aligned with its cage. Therefore, in this structure, a portion of the circumferential space is also unutilized. Furthermore, the filtration efficiency of the cyclone cone assembly is somewhat affected by this structure.

[0006] Overall, in existing stick vacuum cleaners, whether the space occupied by the guide vane towards the external space of the separator assembly or the space occupied by the guide vane towards the internal space of the separator assembly, other unfavorable factors will be introduced that affect performance or user experience, such as an oversized dust cup or the need for an offset design of the cyclone cone assembly. Utility Model Content

[0007] This disclosure provides a dust collection device and a stick vacuum cleaner.

[0008] According to one aspect of this disclosure, a dust collection device is provided, comprising: The housing includes an inlet through which air enters the interior of the housing. The frame portion is disposed inside the outer shell portion; A first separator, disposed in the frame portion, is used to filter air entering through the inlet portion and to introduce the filtered air into the interior of the first separator; and The second separator, housed inside the first separator, is used to separate dust from the filtered air; The frame portion has a tangential feature formed radially inward, so that air introduced into the interior of the housing portion from the inlet portion is guided along the tangential feature to the inner wall of the housing portion, so that the air can at least flow around the first separator and avoid the tangential feature in a spiral manner; wherein the longitudinal axis of the frame portion and the longitudinal axis of the second separator are arranged to coincide.

[0009] According to the technical solution of this embodiment, by forming a tangential feature on the frame portion, gas can be introduced into the contents of the dust collection device. Furthermore, by aligning the longitudinal axis of the frame portion with the longitudinal axis of the second separator, the arrangement of the second separator is facilitated. In other words, in the dust collection device of this disclosure, by re-optimizing the tangential feature, the second separator remains centrally located without increasing the size of the dust collection device. This arrangement ensures that the cyclone cone assembly and the frame portion remain concentrically positioned and that the cyclone cone assembly does not shift eccentrically due to the placement of the guide vane, thus ensuring the normal operation of the stick vacuum cleaner.

[0010] According to at least one embodiment of the dust collection device of the present disclosure, a first space is formed inside the frame portion, the first space including a first occupied space, wherein the tangential feature is disposed in the first occupied space, and the second separator is disposed in a second occupied space; when the longitudinal axis of the frame portion and the longitudinal axis of the second separator are arranged to coincide, the first occupied space and the second occupied space do not overlap.

[0011] According to the technical solution of this embodiment, the arrangement of the tangential features of this disclosure will not affect the arrangement of the second separator, thereby optimizing the layout of the dust collection device and making the dust collection device of the stick vacuum cleaner of this disclosure have a smaller volume and higher gas-solid separation efficiency.

[0012] According to at least one embodiment of the dust collection device of the present disclosure, the tangential feature is formed on the outer surface of the frame portion and extends radially inward along the frame portion to form a first occupancy portion, the first occupancy portion being configured to be located within the first occupancy space, and not interfering with the second separator when the frame portion and the second separator are coaxially arranged.

[0013] According to the technical solution of this embodiment, since the tangential feature and the second separator are arranged without interference, it is beneficial to arrange the tangential feature and also to arrange the second separator.

[0014] According to at least one embodiment of the dust collection device of the present disclosure, when the first separator and the second separator are coaxially arranged, the first occupying portion contacts at least a portion of the second separator.

[0015] According to the technical solution of this embodiment, the volume of the dust collection device disclosed herein can be further reduced by using the tangential features of the contact and the second separator.

[0016] According to at least one embodiment of the dust collection device of the present disclosure, when the first separator and the second separator are coaxially arranged, the first occupier portion is spaced apart from the second separator.

[0017] According to the technical solution of this embodiment, the first occupant and the second separator, which are arranged at intervals, facilitate the arrangement of the tangential features and also facilitate the arrangement of the second separator.

[0018] According to at least one embodiment of the dust collection device of the present disclosure, the first separator is disposed on the frame portion and forms part of the outer surface of the frame portion.

[0019] According to the technical solution of this embodiment, by setting the first separator on the frame part, the first separator can have a large area. Correspondingly, the first separator has little impact on the gas flow rate, so that the gas can flow to the second separator at high speed.

[0020] According to at least one embodiment of the dust collection device of the present disclosure, the longitudinal axis of the first separator and the longitudinal axis of the second separator are arranged to coincide.

[0021] According to the technical solution of this embodiment, by having the longitudinal axes of the first and second separators overlap, the area between the first and second separators can be separated approximately uniformly, allowing gas to flow stably from the area between the first and second separators, thereby reducing turbulence during gas flow. Furthermore, this arrangement of the first and second separators also facilitates the arrangement of the air inlet of the second separator.

[0022] According to at least one embodiment of the dust collection device of the present disclosure, the tangential feature includes an air guiding channel that extends between the inner wall of the housing portion and the outer wall of the first separator, for guiding air into the interior of the housing portion via an inlet portion and for rotating flow around at least the outer surface of the first separator.

[0023] According to the technical solution of this embodiment, by setting the air guide channel, the gas can flow through the inlet of the outer casing and the air guide channel as quickly as possible, thereby preventing dust from accumulating at the inlet of the outer casing and the air guide channel.

[0024] According to at least one embodiment of the dust collection device of this disclosure, the tangential feature includes an inner surface that is close to or in contact with the lower part of the second separator.

[0025] According to the technical solution of this embodiment, since the second separator is a cyclone separator, the lower part of the cyclone separator has a small size. Therefore, by setting a tangential feature near the lower part of the second separator, the size of the dust collection device can be further reduced, and the internal components of the dust collection device can be arranged more compactly.

[0026] According to at least one embodiment of the dust collection device of the present disclosure, the inner surface includes intersecting transverse and longitudinal surfaces, which are connected by a connecting portion.

[0027] According to the technical solution of this embodiment, when gas flows through the area near the longitudinal and transverse surfaces, the longitudinal and transverse surfaces can guide the gas and prevent the structure from generating large resistance to the gas.

[0028] According to at least one embodiment of the dust collection device of this disclosure, the cross-section of the connecting portion is an arc-shaped cross-section.

[0029] According to the technical solution of this embodiment, by setting the connecting part with an arc-shaped cross section, the outer shell of this disclosure can be integrally injection molded. In other words, the dust collection device of this disclosure has a simple manufacturing process and low manufacturing cost.

[0030] According to at least one embodiment of the dust collection device of the present disclosure, the first separator includes a screen configured to intercept airborne dirt particles into the housing portion as air flows spirally around the first separator.

[0031] According to the technical solution of this embodiment, by setting up a screen, larger dirt particles can be filtered out, and the first gas-solid separation of the mixture of gas and dirt can be achieved, thereby reducing the particulate matter content in the gas discharged by the dust collection device.

[0032] According to at least one embodiment of the dust collection device of the present disclosure, the second separator includes a plurality of cyclone cones arranged in parallel, the cyclone cones being uniformly distributed around the longitudinal axis of the second separator and configured to separate dirty particles in the air by cyclone separation.

[0033] According to the technical solution of this embodiment, a cyclone separator is used to further remove fine particulate matter from the air, so that the gas discharged from the dust collection device contains as little particulate matter as possible.

[0034] According to at least one embodiment of the dust collection device of this disclosure, the tangential feature is close to at least one of the cyclone cones.

[0035] According to the technical solution of this embodiment, the tangential feature can be made to be in close contact and connected with the lower end of the cyclone cone, and correspondingly, the size of the dust collection device disclosed herein can be further reduced.

[0036] According to another aspect of this disclosure, a stick vacuum cleaner is provided, which includes the dust collection device described above. Attached Figure Description

Detailed Implementation

[0056] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0057] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0058] Unless otherwise specified, the illustrated exemplary embodiments will be understood to provide exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of various embodiments can be additionally combined, separated, interchanged, and / or rearranged without departing from the technical concept of the present disclosure.

[0059] Figure 1 is a schematic structural diagram of a surface cleaning system according to an embodiment of the present disclosure. Figure 2 is a schematic structural diagram of the surface cleaning system from another angle according to an embodiment of the present disclosure.

[0060] As Figure 1 and Figure 2 shown, the surface cleaning system of the present disclosure may include a surface cleaning device and a docking station 200 that is配套 with the surface cleaning device. The surface cleaning device may be a stick vacuum cleaner 100. The surface cleaning system can provide users with an efficient and convenient cleaning solution. By combining the stick vacuum cleaner 100 with the docking station 200, not only the indoor environment can be cleaned, but also the maintenance and use experience of the stick vacuum cleaner 100 can be optimized through the auxiliary functions of the docking station 200.

[0061] The stick vacuum cleaner 100, as the execution component of the surface cleaning system, is responsible for sucking and collecting foreign matters such as dust and dirt on the surface to be cleaned, while the docking station 200, as its supporting facility, is used for the stick vacuum cleaner 100 to dock and store the stick vacuum cleaner 100. When the stick vacuum cleaner 100 docks at the docking station 200, the docking station 200 can charge the stick vacuum cleaner 100 and automatically process the dirty particles in the dust collection device 140, thereby reducing the operation burden of the user and improving the overall cleaning efficiency.

[0062] Figure 3 is a schematic structural diagram of a stick vacuum cleaner according to an embodiment of the present disclosure.

[0063] As Figure 3 It should be noted that there is an error in the original text where "配套 with" should be "matched with" or other more appropriate expressions. The above translation has been corrected as much as possible while maintaining the original text structure.As shown, the stick vacuum cleaner 100 of this disclosure may include components such as a main body 110, a suction pipe 120, a cleaning head 130, and a dust collection device 140. The main body 110 is connected to the dust collection device 140. The cleaning head 130 is detachably connected to the lower end of the suction pipe 120, and the upper end of the suction pipe 120 is detachably connected to the main body 110 and communicates with the dust collection device 140. Thus, a mixture of dirt and air on the surface to be cleaned can enter the suction pipe 120 from the cleaning head 130 and then enter the dust collection device 140 through the suction pipe 120. After gas-solid separation is completed in the dust collection device 140, the dirt is retained in the dust collection device 140, and the gas is discharged through an opening on the side of the main body 110.

[0064] Therefore, the stick vacuum cleaner 100 disclosed herein is lightweight and flexible, suitable for use in various scenarios such as home and office.

[0065] Specifically, the main body 110 may include a suction motor (not shown), which generates the suction force required to remove foreign objects from the surface to be cleaned. The suction motor is the core power source of the stick vacuum cleaner 100, and its performance directly affects the vacuuming effect. It typically uses a high-efficiency brushless motor, which features low noise, high suction power, and long lifespan.

[0066] The main body 110 may include a handle 150 for the user to grip and operate the stick vacuum cleaner 100. The user can hold the handle 150 and move the stick vacuum cleaner 100 in the back-and-forth direction. The handle 150 is ergonomically designed, typically using non-slip materials and a streamlined shape to ensure a comfortable operating experience for the user even during extended use.

[0067] The main body 110 may include a suction nozzle 160, which is used to connect to the suction tube 120 or the cleaning head 130. The suction nozzle 160 is a key component of the airflow channel, and its internal structure is optimized to ensure that foreign objects can enter the dust collection device 140 smoothly and efficiently, avoiding blockage or suction loss.

[0068] The suction tube 120 can be detachably connected to the nozzle 160, thereby extending the cleaning range. Specifically, users can choose whether to use the suction tube 120 according to their actual cleaning needs. For example, when cleaning higher locations (such as the top of curtains or the ceiling), the suction tube 120 can extend the working range of the stick vacuum cleaner 100, while when cleaning narrow spaces (such as sofa crevices), the nozzle 160 can be directly connected to the cleaning head 130, increasing operational flexibility.

[0069] Furthermore, the nozzle 160 can be configured to connect directly to the cleaning head 130 instead of the suction tube 120, or the nozzle 160 can be connected to other components, such as an auxiliary suction unit. This versatility in connection allows the stick vacuum cleaner 100 to be compatible with a variety of cleaning attachments, such as crevice tools, soft brushes, or mite-removal tools, thereby expanding its functionality and meeting users' cleaning needs in different scenarios.

[0070] The suction tube 120 can be extended to have an extension axis extending in one direction. This extension axis is generally aligned with the overall longitudinal direction of the stick vacuum cleaner 100. Therefore, users can increase cleaning convenience by connecting various components to the nozzle 160 according to the cleaning situation. For example, when cleaning large floor areas, users can choose a longer suction tube 120 and a wide-mouth floor brush combination, while when cleaning furniture surfaces, they can switch to a shorter tube and a soft brush to improve cleaning efficiency and precision.

[0071] The cleaning head 130 can be selectively configured as a floor brush or a bed brush according to cleaning needs to adapt to the cleaning requirements of different surfaces (such as floors, carpets, and mattresses). Taking cleaning a floor surface as an example, the cleaning head 130 may include a base 131, a roller brush 132, and a follower wheel 133. The base 131 has a receiving space with a downward opening, and the roller brush 132 is rotatably disposed on the base 131 and located within the receiving space.

[0072] A gas flow path is also formed on the base 131, which is connected to the accommodating space. The connection point between the gas flow path and the accommodating space (i.e., the dust suction port) is located at the rear of the roller brush 132. Thus, the connection point forms the starting point of the gas flow path. The mixture of dirt and air will enter the gas flow path from here and be guided to the dust collection device 140.

[0073] The follower wheel 133 is rotatably mounted on the base 131. In a preferred embodiment, two follower wheels 133 are provided, located on the left and right sides of the base 131 respectively. Thus, when the user uses the stick vacuum cleaner 100 to clean the floor, the cleaning head 130 can move on the surface to be cleaned and bear most of the weight of the stick vacuum cleaner 100. In a preferred embodiment, the follower wheels 133 are typically made of wear-resistant rubber or plastic, with a diameter of 20-40 mm, and there are two of them to provide a stable support point.

[0074] The dust collection device 140 can be configured in a cylindrical shape, having an extension axis extending substantially parallel to the direction of extension of the suction pipe 120. This design ensures that the airflow path of the dust collection device 140 is consistent with that of the suction pipe 120, reducing airflow resistance and improving dust collection efficiency.

[0075] Specifically, the suction tube 120 can be connected to the nozzle 160 such that the extension axis of the suction tube 120 faces a direction substantially parallel to the extension direction of the dust collection device 140. This axial parallelism helps optimize airflow from the cleaning head 130 to the dust collection device 140, avoiding suction loss or debris accumulation due to angular deviations.

[0076] The dust collection device 140 can be arranged upstream of the suction motor (not shown) in the airflow to filter out dust or dirt from the air introduced through the cleaning head 130 and collect the filtered dust or dirt. As a dust collection component for the stick vacuum cleaner 100, the dust collection device 140 performs the functions of filtering and storing dirt particles during the vacuuming process. Its position upstream of the suction motor effectively protects the motor from dust and extends the service life of the equipment.

[0077] Figure 4 This is a schematic diagram of the structure of a dust collection device according to one embodiment of the present disclosure. Figure 5 This is a structural schematic diagram of a dust collection device according to one embodiment of the present disclosure from another angle.

[0078] like Figure 4 and Figure 5 As shown, the dust collection device 140 of this disclosure may include components such as a housing 141, a frame 142, a first separator 143, and a second separator 144.

[0079] The outer casing 141 of this disclosure is formed in a generally cylindrical structure. One end of the outer casing 141 can be connected to the main body 110, for example, the outer casing 141 can be sealed to the main body 110, thereby allowing gas to flow from the outer casing 141 to the main body 110. In a preferred embodiment, the outer casing 141 may also be integrally formed with the shell of the main body 110, and this disclosure is not limiting.

[0080] An inlet 141A is provided on the outer casing 141, through which air enters the interior of the outer casing 141. This air refers to air carrying dirt particles from the cleaning head. In a preferred embodiment, the inlet 141A is located approximately at the center of the axial direction of the outer casing 141.

[0081] like Figure 4 As shown, the outer casing 141 of this disclosure is also provided with a dust discharge port 141B, wherein the dust discharge port 141B is located at the lower end of the side wall of the outer casing 141 in the axial direction. At this time, the lower end of the outer casing 141 is in a closed state, and correspondingly, the dirt particles stored at the lower end of the outer casing 141 can enter the docking station 200 through the dust discharge port 141B and be collected by the docking station 200.

[0082] The frame portion 142 of this disclosure is disposed inside the outer shell portion 141; in one embodiment, the frame portion 142 can be fixedly connected to the outer shell portion 141, that is, it can be fixed to the inner wall of the outer shell portion 141, so that the frame portion 142 will not be displaced relative to the outer shell portion 141.

[0083] Figure 6 This is a schematic diagram of the internal structure of a dust collection device according to one embodiment of the present disclosure.

[0084] like Figure 6 As shown, a tangential feature 145 is formed on the frame portion 142 of this disclosure, which is formed in a radially inward direction on the frame portion 142. That is, viewed from the outside of the frame portion 142, the tangential feature 145 is a recessed feature formed on the frame portion 142; in other words, viewed from the inside of the frame portion 142, the tangential feature 145 is a protruding feature formed on the frame portion 142.

[0085] Due to the presence of the tangential feature 145, a space for gas flow will be provided between the frame portion 142 and the outer casing portion 141. At this time, the position of the tangential feature 145 corresponds to that of the inlet portion 141A. The gas flowing into the casing portion 141 via the inlet portion 141A will flow through the area between the tangential feature 145 and the outer casing portion 141 and reach the position of the first separator 143. In other words, by setting the tangential feature 145, the air introduced into the interior of the outer casing portion 141 from the inlet portion 141A is guided along the tangential feature 145 to the inner wall of the outer casing portion 141, so that the air can at least flow around the first separator 143 and avoid the tangential feature 145 in a spiral manner; wherein, the longitudinal axis of the frame portion 142 and the longitudinal axis of the second separator 144 are arranged to coincide.

[0086] Therefore, in the dust collection device of this disclosure, by re-optimizing the tangential feature 145, the second separator 144 is kept centrally positioned without increasing the size of the dust collection device 140. With this configuration, the cyclone cone assembly and the frame portion 142 can always remain concentrically positioned without the cyclone cone assembly shifting eccentrically due to the placement of the guide vane, thus ensuring the normal operation of the stick vacuum cleaner 100.

[0087] In a preferred embodiment, the tangential feature 145 can extend circumferentially along the frame portion 142 to the inner wall of the outer casing portion 141. Thus, the rotating airflow of this disclosure will not flow to the tangential feature 145, that is, the gas will avoid the tangential feature 145 and flow in a spiral manner, thereby improving the air intake efficiency through the inlet portion 141A and effectively preventing dust from accumulating at the inlet portion 141A.

[0088] Specifically, a first space is formed inside the frame portion 142, including a first occupied space, wherein the tangential feature 145 is disposed in the first occupied space, and the second separator 144 is disposed in the second occupied space; when the longitudinal axis of the frame portion 142 and the longitudinal axis of the second separator 144 are arranged to coincide, the first occupied space and the second occupied space do not overlap. Therefore, the arrangement of the tangential feature 145 of this disclosure will not affect the arrangement of the second separator 144, thereby optimizing the layout of the dust collection device 140, so that the dust collection device 140 of the stick vacuum cleaner 100 of this disclosure has a smaller volume and higher gas-solid separation efficiency.

[0089] In this disclosure, a first separator 143 is disposed in the frame portion 142 for filtering air entering through the inlet portion 141A and introducing the filtered air into the interior of the first separator 143; a second separator 144 is housed inside the first separator 143 for separating dust from the filtered air. The first separator 143 includes a screen configured to intercept airborne dirt particles as the air flows spirally around the first separator 143, directing them into the outer casing portion 141. This allows for the filtering of larger dirt particles, which then collect at the lower end of the dust collection device 140 due to gravity.

[0090] In a preferred embodiment, the second separator 144 includes a plurality of cyclone cones 144A arranged in parallel, the cyclone cones 144A being evenly distributed around the longitudinal axis of the second separator 144 and configured to separate dirty particles in the air through cyclone separation. Thus, in the stick vacuum cleaner 100 of this disclosure, smaller dust particles can be separated by the cyclone separator, thereby effectively reducing the particulate matter content in the air discharged from the main body 110.

[0091] The structure of the tangential feature 145 will now be described in detail with reference to the accompanying drawings.

[0092] Figures 7 to 9 This is a schematic diagram of the internal structure of a dust collection device according to one embodiment of the present disclosure from different angles.

[0093] like Figures 6 to 9 As shown, the tangential feature 145 of this disclosure is formed on the outer surface of the frame portion 142 and extends radially inward along the frame portion 142 to form a first occupying portion. The first occupying portion is configured to be located within the first occupying space. When the frame portion 142 and the second separator 144 are coaxially arranged, it does not interfere with the second separator 144. Therefore, in the dust collection device 140 of this disclosure, the guide formed by the tangential feature 145 will not affect the arrangement of the second separator 144. Accordingly, the dust collection device 140 of this disclosure also has a smaller volume.

[0094] When the first separator 143 and the second separator 144 are coaxially arranged, the first occupier contacts at least a portion of the second separator 144. Thus, in the dust collection device 140 of this disclosure, the tangential feature 145 and the second separator 144 can be arranged closely together, thereby further reducing the size of the dust collection device 140.

[0095] When the first separator 143 and the second separator 144 are coaxially arranged, there is a gap between the first occupant and the second separator 144. Therefore, during the assembly of the dust collection device 140 of this disclosure, the second separator 144 can be conveniently installed inside the dust collection device 140 without considering interference issues, thereby improving the assembly efficiency of the dust collection device 140.

[0096] In some embodiments, the first separator 143 is disposed on the frame portion 142, forming part of the outer surface of the frame portion 142. In other words, the screen can be fitted over the outside of the frame portion 142, so that all gas entering the second separator 144 needs to be filtered through the screen, thereby making the gas entering the second separator 144 cleaner, so as to facilitate the cyclone separator to perform cyclone separation on the filtered gas.

[0097] In this disclosure, the longitudinal axis of the first separator 143 and the longitudinal axis of the second separator 144 are arranged to coincide. Therefore, the first separator 143 can have a large filtration area, and correspondingly, its resistance to gas flow can be minimized. Furthermore, the coaxial arrangement of the first separator 143 and the second separator 144 allows for a compact arrangement of the internal components of the dust collection device 140.

[0098] like Figure 6 As shown, the tangential feature 145 of this disclosure includes an air guide channel 145A that extends between the inner wall of the housing portion 141 and the outer wall of the first separator 143, for guiding air from the inlet portion 141A into the interior of the housing portion 141 and for rotating flow around at least the outer surface of the first separator 143.

[0099] In a preferred embodiment, the tangential feature 145 includes an inner surface that is close to or in contact with the lower portion of the second separator 144. Since the second separator 144 is a cyclone separator, the lower portion of which has a small size, providing the tangential feature 145 near the lower portion of the second separator 144 can further reduce the size of the dust collection device 140 and allow the internal components of the dust collection device 140 to be arranged more compactly.

[0100] Specifically, the inner surface includes intersecting transverse surface 145B and longitudinal surface 145C, which are connected by a connecting portion 145D. More preferably, the connecting portion 145D has an arc-shaped cross-section, thereby allowing the transverse surface 145B and longitudinal surface 145C to be smoothly connected, and in this case, the frame portion 142 can be easily injection molded. The longitudinal surface 145C is positioned close to or against the second separator 144.

[0101] More preferably, the tangential feature 145 is close to at least one of the cyclone cone 144A. This arrangement allows the tangential feature 145 to be in close contact with and connected to the lower end of the cyclone cone 144A. Accordingly, the size of the dust collection device 140 of this disclosure can be further reduced.

[0102] Figure 10 This is a schematic diagram of a cyclone separator according to one embodiment of the present disclosure. Figure 11 This is a structural schematic diagram of a cyclone separator according to one embodiment of the present disclosure from another angle.

[0103] like Figure 10 and Figure 11 As shown, the second separator 144 of this disclosure can be a cyclone separator, which can also be referred to as a secondary cyclone separator, thereby achieving the separation of gas and small-sized dirt through the cyclone separator.

[0104] Specifically, the cyclone separator disclosed herein includes a plurality of cyclone cones 144A, each of which is formed in a conical shape, and the diameter of the cyclone cone 144A gradually decreases along the direction from the apex to the base of the cone. In other words, the diameter (including the inner and outer diameters) of the cyclone cone 144A gradually decreases along the direction from top to bottom.

[0105] Specifically, the plurality of cyclone cones 144A are divided into at least a first group of cyclone cones 144A and a second group of cyclone cones 144A located outside the first group of cyclone cones 144A, wherein the intersection of the longitudinal axes of the first group of cyclone cones 144A is at a different height in the longitudinal direction than the intersection of the longitudinal axes of the second group of cyclone cones 144A. More preferably, the intersection of the longitudinal axes of the first group of cyclone cones 144A is further away from the plurality of cyclone cones 144A in the longitudinal direction than the intersection of the longitudinal axes of the second group of cyclone cones 144A.

[0106] In other words, these cyclone cones 144A are arranged at different tilt angles, thus allowing them to be conveniently arranged.

[0107] Specifically, such as Figure 10As shown, the cyclone separator of this disclosure may include 12 cyclone cones 144A, wherein the first group of cyclone cones 144A is the inner ring of cyclone cones 144A, which includes three cyclone cones 144A. The second group of cyclone cones 144A is the outer ring of cyclone cones 144A, which includes nine cyclone cones 144A. Thus, the first group of cyclone cones 144A of this disclosure can be located inside the second group of cyclone cones 144A.

[0108] At this time, the first set of cyclone cones 144A has a smaller tilt angle than the second set of cyclone cones 144A. As a result, the second set of cyclone cones 144A of this disclosure is arranged closer to the axial direction of the cyclone separator (i.e., the axis of the frame portion 142), thereby making the cyclone separator occupy a smaller volume to facilitate the arrangement of the tangential feature 145.

[0109] The longitudinal axis of each cyclone cone 144A in the second group of cyclone cones 144A is offset at an angle relative to the longitudinal axis of each cyclone cone 144A in the first group of cyclone cones 144A. That is, the axis of each cyclone cone 144A in the first group of cyclone cones 144A of this disclosure has a small angle with the axis of the cyclone separator, while the axis of each cyclone cone 144A in the second group of cyclone cones 144A has a larger angle with the axis of the cyclone separator. At this time, there will be a certain angle between the axis of the cyclone cones in the first group of cyclone cones and the axis of the cyclone cones in the second group of cyclone cones. Therefore, compared with the first group of cyclone cones 144A, the second group of cyclone separators 144A gradually moves closer to the axis of the cyclone separator in the direction from top to bottom.

[0110] like Figure 10 As shown, the portion near the top of the cone includes at least one inlet, and the portion near the bottom of the cone includes an outlet. The inlet is connected to an air intake passage, which includes a first blade 144B. The first blade 144B is formed to be tangent to the inner surface of the inlet of the cyclone cone 144A and is configured in an arc shape so that the air intake passage has a wider passage relative to the inlet.

[0111] In other words, unlike the planar first blades in the prior art, the first blade 144B of this disclosure is designed as an arc shape. Therefore, the cyclone separator of this disclosure has an increased lateral air intake width. Correspondingly, the cyclone separator of this disclosure can increase the air intake area of ​​the cyclone cone without increasing the inlet height, thereby improving the separation effect of the cyclone separator. Moreover, this design also facilitates the arrangement of the cyclone cones in the cyclone separator.

[0112] In a preferred embodiment, the arc angle is greater than 15°. Preferably, the arc angle is between 15° and 20°. Thus, the intake channel of this disclosure has a relatively long dimension, and correspondingly, the turbulence of the gas within the intake channel can be effectively reduced, resulting in a higher flow velocity of the gas within the cyclone cone 144A, thereby improving the gas-solid separation effect of the cyclone separator.

[0113] The air intake channel includes a second blade 144C at a first angle relative to the first blade 144B. The first blade 144B and the second blade 144C form the sidewall of the air intake channel, and the first angle is greater than or equal to 0°. Therefore, the gas entering the cyclone cone 144A is guided by the constricted air intake channel, resulting in stronger directionality after entering the cyclone cone 144A. This means the gas can move along the sidewall of the cyclone separator as much as possible, thereby improving the gas-solid separation effect of the cyclone separator.

[0114] In one specific embodiment, the first blade 144B has a height between 10 mm and 20 mm, and the air intake channel has a width between 4 and 10 mm. Thus, the air intake channel of this disclosure has low motion resistance and can easily arrange these cyclone cones together to form a cyclone separator.

[0115] In this disclosure, the air intake passage can extend along a preset rotation direction. Figure 10 and Figure 11 As shown, the preset rotation direction can be clockwise or counterclockwise. Those skilled in the art can select a suitable arrangement direction based on the arrangement position of the cyclone cone 144A, which will not be elaborated further in this disclosure.

[0116] In a preferred embodiment, the arc-shaped first blade 144B has approximately the same curvature as the interior of the cyclone cone 144A, thereby providing better guidance.

[0117] Therefore, the cyclone separator disclosed herein, through the design of the arc-shaped first blade, significantly increases the side air intake area of ​​the cyclone cone without increasing the inlet height, thereby reducing wind resistance and improving overall separation efficiency. According to the Darcy-Weisbach principle, this design reduces the impact of the circumference of the inner wall of the air duct on flow resistance, which is beneficial for optimizing the overall performance of the machine. At the same time, the arc curvature is close to the circular curvature inside the cone, improving the airflow guidance effect, reducing airflow collision and energy loss, and facilitating arrangement in limited spaces. This solution enhances the dust removal capacity and energy utilization efficiency of vacuum cleaners, possessing higher practicality and market competitiveness.

[0118] Figure 12 This is a schematic diagram of the structure of a docking station according to one embodiment of the present disclosure. Figure 13yes Figure 12 Enlarged schematic diagram of part A.

[0119] like Figure 12 and Figure 13 As shown, the docking station 200 of this disclosure includes structures such as a base 210, a dust-collecting component 201 (not shown in the figure), a recess 220, and a roller 230.

[0120] In addition, the docking station 200 of this disclosure also includes a base 240. The base 240 of this disclosure is formed as a support component of the entire docking station 200, and the base 240 is connected to the lower end of the base portion 210 to support the base portion 210.

[0121] The base portion 210 of this disclosure has an internal space, and a dust collection component 201 is disposed inside the base portion 210 and configured to remove dirt collected in the dust collection device 140 of the stick vacuum cleaner 100 when the stick vacuum cleaner 100 is docked at the docking station 200.

[0122] Specifically, the negative pressure provided by the suction component 201 can transfer dirt from the dust collection device 140 of the stick vacuum cleaner 100 to the docking station 200. Those skilled in the art will understand that the interior of the base portion 210 of the docking station 200 may also include a dirt particle collection section 202, which may be located upstream of the suction component 201. The dirt transferred from the dust collection device 140 to the docking station 200 can be stored in this dirt particle collection section 202.

[0123] The recess 220 of this disclosure is formed by recessing inward from the outer surface of the base portion 210; when the stick vacuum cleaner 100 is docked at the docking station 200, the recess 220 is used to receive at least a portion of the stick vacuum cleaner 100 and to at least partially support the stick vacuum cleaner 100. In other words, the recess 220 of this disclosure can also be referred to as a support portion.

[0124] The recess 220 includes a sidewall and a bottom wall; in other words, the recess 220 of this disclosure can be limited by the sidewall and the bottom wall. In a preferred embodiment, the bottom wall is formed in a generally circular shape, the sidewall is formed in a generally cylindrical shape, and has a circumferential opening through which the stick vacuum cleaner 100 can enter and exit the recess 220.

[0125] A dust collection port 221 is also provided on the side wall of the recess 220. This dust collection port 221 can communicate with the aforementioned dirt particle collection section 202 (gas in the dust collection port 221 can enter the dirt particle collection section 202, and the gas can pass through the dirt particle collection section 202 into the suction component 201, so that the dirt particles are stored inside the dirt particle collection section 202). That is, the dust collection port 221 is indirectly connected to the suction component 201. When the stick vacuum cleaner 100 is docked at the docking station 200, the dust discharge port 141B communicates with the dust collection port 221, so that the dust discharged from the dust discharge port 141B of the dust collection device 140 can enter the dirt particle collection section 202 through the dust collection port 221 and be stored inside the dirt particle collection section 202. In a specific embodiment, the dirt particle collection section 202 can be a dust bag, and the dust bag is permeable to gas, so that the dirt particles are retained inside the dust bag. When the amount of dirt particles inside the dust bag reaches a certain level, the user can open the cover of docking station 200 and remove the entire dust bag from docking station 200, replacing it with a new dust bag. In other words, at this point, the dust bag is a disposable item. Of course, in another embodiment, the dust bag can also be reused, and this disclosure does not limit this.

[0126] The roller 230 is rotatably disposed on the side wall of the recess 220. When the stick vacuum cleaner 100 is docked to or detached from the docking station 200, the roller 230 is driven to rotate by at least a portion of the dust collection device 140 of the stick vacuum cleaner 100.

[0127] Therefore, the docking station 200 of this disclosure, through the setting of the rollers 230, can guide the stick vacuum cleaner 100 when docking with or detaching from the docking station 200, thereby effectively reducing the friction between the stick vacuum cleaner 100 and the docking station 200 and preventing damage to the outer surface of the stick vacuum cleaner 100. In other words, the setting of the rollers 230 not only facilitates the user in docking or detaching the stick vacuum cleaner 100 from the docking station 200, but also prevents damage to the stick vacuum cleaner.

[0128] In a preferred embodiment, the rotation axis of the roller 230 is a horizontal axis. In other words, the roller 230 of this disclosure can guide the vertical movement of the stick vacuum cleaner 100. This vertical movement does not refer to the stick vacuum cleaner 100 moving in a vertical direction, but rather to a change in position of the stick vacuum cleaner 100 at a certain point in the height direction.

[0129] The roller 230 of this disclosure is located above the dust collection port 221. In other words, when the dust collection device 140 is supported on the support platform, the roller 230 is located above the dust discharge port 141B of the dust collection device 140. Therefore, the roller 230 of this disclosure, in this position, can more easily guide the movement of the stick vacuum cleaner 100. In other words, when the stick vacuum cleaner 100 is docked to or detached from the docking station, the upper end of the dust collection device 140 needs to be guided more than the lower end.

[0130] Therefore, when the stick vacuum cleaner 100 docks to or detaches from the docking station 200, the roller 230 rolls along the upper part of the dust discharge port 141B of the dust collection device 140.

[0131] In other words, when the stick vacuum cleaner 100 is docked to or detached from the docking station 200, the roller 230 can be driven and rolled by the upper part of the dust discharge port 141B of the dust collection device 140.

[0132] In this disclosure, the bottom wall of the recess 220 is formed as a support platform for the stick vacuum cleaner 100. A guide terminal 250 is provided on the support platform. The guide terminal 250 is configured such that when the stick vacuum cleaner 100 is docked to the docking station 200, the bottom of the dust collection device 140 receives a preload from the guide terminal 250 and is configured to hook the side of the dust collection device 140 when the dust collection device 140 is supported on the support platform. Thus, by providing the guide terminal 250, the stick vacuum cleaner 100 can be stably held on the docking station 200.

[0133] The docking station 200 also includes a plurality of fixed terminals 260 disposed on the support platform. When the dust collection device 140 is supported on the support platform, the fixed terminals 260 hook the bottom of the dust collection device 140. Thus, by setting the fixed terminals 260, the stick vacuum cleaner 100 can be stably held on the docking station 200.

[0134] The docking station 200 also includes a charging terminal 270 and / or a communication terminal mounted on the side wall of the base portion 210, for charging the stick vacuum cleaner 100 via the charging terminal 270, or for communication between the docking station 200 and the stick vacuum cleaner 100 via the communication terminal. In a preferred embodiment, the charging terminal 270 and the communication terminal can be formed as a shared terminal, that is, both charging and communication functions can be realized through the shared terminal.

[0135] Figure 14 yes Figure 12 Enlarged schematic diagram of part B.

[0136] like Figure 14 As shown, when the stick vacuum cleaner 100 is docked to or detached from the docking station 200, the cleaning head 130 of the stick vacuum cleaner 100 is supported on the base 240.

[0137] Preferably, the base 240 includes a tray with a receiving space configured to receive the cleaning head 130 of the stick vacuum cleaner 100 when the stick vacuum cleaner 100 is docked to the docking station 200.

[0138] Therefore, the cleaning head 130 of the stick vacuum cleaner 100 of this disclosure can be placed in the receiving space of the docking station 200, thereby supporting the weight of the stick vacuum cleaner 100. Accordingly, the user can dock the stick vacuum cleaner 100 to the docking station 200 without overcoming the weight of the stick vacuum cleaner.

[0139] Specifically, the accommodating space includes a first accommodating space 241, which is formed in the form of a groove and is consistent with the shape of the cleaning head 130 of the stick vacuum cleaner 100, thereby allowing the cleaning head 130 to be held inside the first accommodating space 241.

[0140] In a preferred embodiment, the first receiving space 241 includes an inclined surface that slopes upward toward the rear of the docking station 200 at a first angle, the first angle being greater than 0° and less than or equal to 15°. This allows the user to easily push the cleaning head 130 of the stick vacuum cleaner 100 onto the inclined surface of the base 240 without lifting the stick vacuum cleaner 100, thus facilitating the user's docking of the stick vacuum cleaner 100 to the docking station 200.

[0141] The receiving space also includes a second receiving space 242, which is formed by a downward recess from the bottom wall of the first receiving space 241. The shape of the second receiving space 242 is consistent with that of the roller brush 132 of the cleaning head 130. Thus, the roller brush 132 of the stick vacuum cleaner 100 of this disclosure can be supported by the base 240, while also preventing the cleaning head 130 from sliding out of the docking station.

[0142] The receiving space also includes a third receiving space 243, which is formed by a downward recess from the bottom wall of the first receiving space 241. The shape of the third receiving space 243 is consistent with that of the follower wheel 133 of the cleaning head 130. The follower wheel 133 of the stick vacuum cleaner 100 of this disclosure can be supported by the base 240, and at the same time, it can prevent the cleaning head 130 from sliding out of the docking station 200.

[0143] In a preferred embodiment, the second receiving space 242 includes an opening 244 communicating with the interior of the base portion 210. When the stick vacuum cleaner 100 is docked at the docking station 200, the opening 244 communicates with the interior of the dust collection device 140 of the stick vacuum cleaner 100, so as to provide exhaust airflow to the interior of the dust collector through the opening 244. Thus, the surface cleaning system of this disclosure can form a circulating airflow when in operation. That is, when the suction component 201 of the docking station 200 is in operation, it exhausts gas, which can be further provided to the stick vacuum cleaner 100 through the opening 244, thereby avoiding the situation where the exhaust gas contains particulate matter that pollutes the indoor air.

[0144] In a preferred embodiment, the cleaning head 130 includes a suction port. When the stick vacuum cleaner 100 is docked at the docking station 200, the opening 244 and the suction port of the cleaning head 130 are connected via a second receiving space 242, whereby gas can flow through the opening 244 to the suction port and further to the stick vacuum cleaner 100.

[0145] In this disclosure, the opening 244 is located on the side of the second receiving space 242, so that dirt on the roller brush 132 will not fall into the base 240 through the opening 244, and correspondingly, the docking station 200 of this disclosure can be easily cleaned.

[0146] The cleaning head 130 includes a front edge formed as the front edge of the base 131. The front edge is configured to abut against the edge of the receiving space when the stick vacuum cleaner 100 is docked on the docking station 200, thereby enabling the docking station 200 of this disclosure to position the stick vacuum cleaner 100. Accordingly, the positioned stick vacuum cleaner 100 can be more easily placed on the docking station 200.

[0147] Figure 15 This is a schematic diagram of the structure of a docking station 200 according to one embodiment of the present disclosure. Figure 16 This is a schematic diagram of the structure of a cleaner module 280 according to one embodiment of the present disclosure.

[0148] like Figure 15 and Figure 16 As shown, the docking station 200 of this disclosure also includes a cleaner module 280, wherein the cleaner module 280 is detachably disposed on the base portion 210 and is configured to receive the gas discharged by the vacuuming component 201 and remove foreign objects from the gas discharged by the vacuuming component 201.

[0149] Therefore, in the docking station 200 disclosed herein, the cleaning module 280 enables the gas discharged by the vacuuming component 201 to be cleaner, thereby ensuring that the gas discharged by the docking station 200 does not pollute indoor air or minimizes the degree of indoor air pollution.

[0150] Furthermore, since the cleaner module 280 of this disclosure is detachably connected to the base portion 210, the cleaner module 280 can be easily replaced, cleaned, and maintained. In other words, when the cleaner module 280 of this disclosure accumulates a large amount of dirt, it can be detached from the base portion 210 to clean the dirt, and then the cleaned cleaner module 280 can be installed back onto the base portion 210. Additionally, when the cleaner module 280 is damaged, a new cleaner module 280 can be easily installed.

[0151] In a preferred embodiment, when the cleaner module 280 is mounted on the base portion 210, at least a portion of the surface of the cleaner module 280 is formed as a portion of the outer surface of the docking station 200. In this case, the user can directly detach the cleaner module 280 from the docking station 200, or directly mount the cleaner module 280 onto the docking station 200.

[0152] like Figure 16 As shown, the cleaner module 280 of this disclosure includes a module body 281 and a filter 282; wherein the module body 281 is configured to be detachably disposed on the base portion 210, and at least a portion of the surface of the module body 281 is formed as a portion of the outer surface of the docking station 200.

[0153] Specifically, the module body 281 can be formed in a roughly drawer shape, so as to... Figure 16 The square shown has its right-end surface used to form part of the outer surface of the docking station 200. At this time, an operation hole can be provided on the right-end surface of the module body 281, and the user can insert his / her finger into the operation hole to pull the cleaner module 280 out of the base part 210 or install it onto the base part 210.

[0154] The module body 281 disclosed herein may include two sides, on which guide rails 283 may be provided, and a buckle 284 may be provided at the end of the guide rails 283 away from the operating hole.

[0155] The filter 282 disclosed herein is disposed on the module body 281 and is used to filter foreign objects in the gas discharged by the dust collection component 201. In a preferred embodiment, the filter 282 may be a component with filtration performance, such as a filter screen, filter cotton, or HEPA module.

[0156] The filter 282 has a force-bearing surface. When the cleaner module 280 is used in conjunction with the base part 210, the force-bearing surface receives the exhaust force exerted by the airflow discharged by the suction component 201. As a result, the gas discharged by the suction component 201 can pass through the cleaner module 280 at a faster speed. As a result, the docking station 200 of this disclosure can smoothly exhaust gas to the outside and allow the gas to flow through the dust collection device 140 at a higher flow rate. At this time, the dirt in the dust collection device 140 can be removed as cleanly as possible.

[0157] Therefore, the cleaner module 280 of this disclosure can be directly or indirectly fixed to the base portion 210 as a whole. In one implementation, the docking station 200 may further include a support frame 290, which can be fixed inside the base portion 210. The vacuuming component 201 is placed on the upper part of the support frame 290, and an exhaust flow path is formed inside the support frame 290. The exhaust port 213 communicates with the exhaust flow path and is located on the bottom surface of the base portion 210 and is oriented towards the tray to guide the airflow in the support frame 290 toward the tray.

[0158] At this time, a through hole 211 is provided on the front surface of the base portion 210, and at least a portion of the cleaner module 280 is inserted into the interior of the base portion 210 through the through hole 211. At this time, a mounting hole 291 is provided on the support frame 290, and a guide groove that mates with the guide rail 283 is formed on the side wall of the mounting hole 291, and a snap-fit ​​groove that mates with the buckle 284 is provided at the end of the guide groove. Thus, the cleaner module 280 of this disclosure can be stably held in the mounting hole 291 of the support frame 290.

[0159] The base portion 210 of this disclosure includes an exhaust section 212, and the vacuuming component 201 is also connected to the exhaust section 212, such that the exhaust section 212 forms an exhaust flow path downstream of the vacuuming component 201, and the cleaner module 280 is located in the exhaust flow path. In other words, the support frame 290 of this disclosure can also be disposed in the exhaust flow path, in which case the exhaust flow path of the support frame 290 and the exhaust flow path of the exhaust section 212 can be partially overlapped.

[0160] The base portion 210 has an exhaust port 213, which is connected to the exhaust flow path and is used to discharge the airflow in the exhaust flow path to the exhaust section 212 in a direction that is approximately the same as the extension direction of the base portion 210. When the cleaner module 280 is combined with the base portion 210 for use, the cleaner module 280 is located upstream of the exhaust port 213.

[0161] Therefore, the gas discharged by the cleaner module 280 of this disclosure is the treated gas, and correspondingly, the gas discharged through the exhaust port 213 contains fewer particulate matter and will not cause pollution to the indoor environment.

[0162] In addition, the gas discharged by the vacuuming component 201 through the exhaust port 213 is discharged towards the tray so that during the operation of the vacuuming component 201, a portion of the discharged airflow is sucked into the stick vacuum cleaner 100 through the cleaning head 130 to form a circulating flow path, and another portion of the airflow discharged through the exhaust port 213 is discharged into the atmosphere near the cleaning head 130.

[0163] Therefore, when the surface cleaning system of this disclosure is in use, and when transferring dirt from the dust collection device 140 to the docking station 200, the gas used to transfer the dirt can be at least partially circulated, thereby reducing the amount of gas emitted by the docking station 200 into the environment. Considering that the gas emitted by the docking station 200 into the environment may contain some particles, the solution of this disclosure can reduce the total amount of particulate matter emitted by the docking station 200 into the environment, thus improving the user experience.

[0164] The circulating flow path disclosed herein includes at least the gas flow path in the base 210, the base 240, and the stick vacuum cleaner 100. In other words, starting from the cleaning head 130 of the stick vacuum cleaner, the gas flows through the suction pipe 120, the nozzle 160, the dust collection device 140, the dust collection port 221, the dirt particle collection section 202, the suction component 201, and the cleaner module 280, and then exits from the exhaust port 213. At least a portion of the gas exiting from the exhaust port 213 can enter the cleaning head 130, thereby realizing internal gas circulation.

[0165] The front end of the cleaner module 280 is configured to adapt to the front surface of the base portion 210. Thus, when the cleaner module 280 is installed on the base portion 210, the front surface of the docking station 200 can be formed as a smooth surface, thereby making the docking station 200 of this disclosure look very aesthetically pleasing.

[0166] In this disclosure, when the stick vacuum cleaner 100 is docked on the docking station 200, the stick vacuum cleaner 100 is located in front of the docking station 200. At this time, the user cannot remove the cleaner module 280 from the base 210. This avoids the problem of the cleaner module 280 being improperly removed during the process of transferring dirt, thus preventing untreated air pollution of the indoor environment.

[0167] The base 240 includes a tray; during the docking of the stick vacuum cleaner 100 to the docking station 200, the tray is used to position the cleaning head 130 of the stick vacuum cleaner 100, so that the main body of the stick vacuum cleaner 100 moves toward the docking station 200 with the cleaning head 130 as a fulcrum. Thus, the user can easily dock the stick vacuum cleaner 100 to the docking station 200 by pushing the stick vacuum cleaner 100 and rotating the main body 110 relative to the cleaning head 130.

[0168] Figure 17 This is a schematic diagram of the internal structure of a docking station according to one embodiment of the present disclosure.

[0169] like Figure 17 As shown, the docking station 200 of this disclosure further includes a circuit board box 300, which includes a main heat dissipation surface located in the exhaust flow path. Therefore, when in use, the docking station of this disclosure can cool the circuit board box 300 through the airflow in the exhaust flow path, enabling the electronic components inside the circuit board box 300 to operate normally. Furthermore, because these electronic components are in a suitable temperature environment, their lifespan can be extended accordingly.

[0170] Specifically, the circuit board box 300 has an overall box structure, and the circuit boards can be placed inside the circuit board box 300. Moreover, the circuit board box 300 can form an airtight structure, so gas will not enter the interior of the circuit board box 300, and correspondingly, dust will not accumulate on the circuit boards, thus improving the service life of the circuit boards.

[0171] The circuit board may include some electronic components that generate heat. These electronic components may be directly or indirectly connected to the circuit board housing 300 through heat-conducting elements. Thus, the heat generated by these electronic components can be transferred to the circuit board housing 300 and carried away by the gas flowing around the circuit board housing 300.

[0172] In this disclosure, the upper end of the circuit board box 300 can be fixed to the support frame 290. In other words, the circuit board box 300 of this disclosure is located below the support frame 290 and also below the cleaner module 280.

[0173] In a preferred embodiment, the main heat dissipation surface is arranged along the airflow direction in the exhaust flow path. Therefore, while the airflow exchanges heat with the main heat dissipation surface, the main heat dissipation surface does not generate significant resistance to the gas in the exhaust flow path. In other words, in the docking station 200 of this disclosure, heat dissipation of the main heat dissipation surface can be achieved with minimal impact on airflow.

[0174] When the stick vacuum cleaner 100 is docked to the docking station 200, a gap is formed between the receiving space and the cleaning head 130. As a result, the gas discharged from the exhaust port 213 and the ambient air can flow through this gap to the cleaning head 130, and further, this air can enter the stick vacuum cleaner 100 to remove dirt from the dust collection device 140.

[0175] Specifically, during the operation of the vacuuming component 201, a portion of the airflow discharged by the vacuuming component 201 flows along the gap, thereby enabling the airflow to reach the cleaning head 130 and enter the stick vacuum cleaner 100 through the cleaning head 130, so as to realize the circulation of gas between the stick vacuum cleaner 100 and the docking station 200.

[0176] In one implementation of this disclosure, the first receiving space 241 includes a sidewall and a bottom wall. A gap is formed between the sidewall of the first receiving space 241 and the side surface of the base of the cleaning head 130, and / or between the bottom wall of the first receiving space 241 and the bottom surface of the base 131 of the cleaning head 130. That is, the size of the first receiving space 241 is larger than the size of the cleaning head 130, thereby creating a gap between the cleaning head 130 and the sidewall of the first receiving space 241, allowing gas to flow in the gap and enter the suction port, thus forming a circulating airflow.

[0177] In this disclosure, the second and third accommodating spaces 242 and 243 are relatively shallow, allowing the bottom surface of the base 131 of the cleaning head 130 to be suspended in the air. In this case, the bottom surface of the base 131 of the cleaning head 130 does not contact the bottom wall of the first accommodating space 241; that is, a gap is formed between the bottom surface of the base 131 of the cleaning head 130 and the bottom wall of the first accommodating space 241, allowing gas to flow within this gap and enter the suction port of the cleaning head 130 with minimal resistance. Of course, the depth of the second and third accommodating spaces 242 and 243 must at least be sufficient to ensure that the cleaning head 130 can be stably held by the base.

[0178] Figure 18 This is a structural schematic diagram of the base of a docking station according to one embodiment of the present disclosure.

[0179] In another implementation of this disclosure, a groove 245 is provided on the bottom wall of the first receiving space 241, which is connected to the second receiving space 242. Thus, gas flowing through the gap can enter the cleaning head 130 through the groove 245, thereby reducing the resistance of the gas when entering the cleaning head 130.

[0180] Specifically, the groove 245 can be configured as four, with two of the four grooves 245 located at one end of the length direction of the second receiving space 242 and the other two located at the other end of the length direction of the second receiving space 242. Thus, gas can enter the cleaning head 130 through both sides, thereby further reducing the flow resistance of gas entering the cleaning head.
