Description

Technical Field

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

[0002] A vacuum cleaner, as a type of cleaning device, typically consists of a main body and a dust collection unit. The main body houses the motor, while the dust collection unit contains a separator within its dust collection chamber. During operation, the motor generates negative pressure, drawing in air and dust particles along with the dirt. The airflow carrying the dust particles rotates at high speed within the dust collection chamber, using centrifugal force to separate the dust particles from the air, thus achieving the cleaning purpose.

[0003] However, after prolonged use, a large amount of dust and debris accumulates in the dust collection chamber, requiring regular cleaning. Current technology uses multiple stacked dust collection chambers for multi-stage separation, but this requires the operator to remove each chamber from the vacuum cleaner body one by one for cleaning. This method involves numerous steps and is relatively cumbersome, affecting ease of use. Utility Model Content

[0004] In view of this, the present invention provides a vacuum cleaner, which aims to simplify the operation steps of cleaning the vacuum cleaner.

[0005] This utility model provides a vacuum cleaner including a motor, a first dust collection chamber, and a second dust collection chamber. The first dust collection chamber has a first discharge port, and the second dust collection chamber has a second discharge port. The second dust collection chamber is separated from and connected to the first dust collection chamber. The first dust collection chamber, the second dust collection chamber, and the motor are arranged along a first direction. The vacuum cleaner also includes a cover configured to close or open the first and second discharge ports. In the closed state, the cover covers the first and second discharge ports, and the length direction of the cover is consistent with the first direction; in the open state, the cover exposes the first and second discharge ports to allow waste to be discharged.

[0006] During vacuum cleaner operation, the cover is in the closed position, shutting off the first and second waste discharge ports. At this time, the motor operates, creating negative pressure inside the vacuum cleaner, drawing in external airflow. When the airflow carrying dust and other debris enters the first and second dust collection chambers, it is trapped within them. When the vacuum cleaner finishes operating, the cover switches from the closed to the open position, opening the first and second waste discharge ports, allowing the dust and debris from both chambers to be discharged together.

[0007] According to the vacuum cleaner provided by this utility model, the cover is positioned on one side perpendicular to the arrangement direction of the first and second dust collection chambers. Therefore, the cover can be switched from the closed state to the open state to discharge dirt without having to remove the first and second dust collection chambers from the vacuum cleaner separately. This implementation simplifies the operation steps of cleaning the vacuum cleaner, making it more convenient and effectively saving time.

[0008] In one possible implementation, the first dust collection chamber and the second dust collection chamber are separated by a first partition. The first partition has a connecting part through which fluid flows from the first dust collection chamber into the second dust collection chamber. When closed, the cover is perpendicular to the first partition.

[0009] According to the vacuum cleaner provided by this utility model, after the airflow carrying dirt is sucked in, it passes through the first dust collection chamber and the second dust collection chamber in sequence. In this way, the vacuum cleaner can achieve two-stage separation, thereby improving the separation efficiency of dirt such as dust and clean airflow.

[0010] In one possible implementation, the motor is located on the side of the second dust collection chamber away from the first dust collection chamber.

[0011] The first dust collection chamber, the second dust collection chamber, and the motor are arranged sequentially along the first direction, which reduces airflow turning and turbulence, lowers energy loss, and thus improves suction efficiency. In addition, the motor is located on the side of the second dust collection chamber away from the first dust collection chamber, which can also reduce the size of the vacuum cleaner in the second direction perpendicular to the first direction, contributing to a compact layout and a miniaturized overall design.

[0012] In one possible implementation, the vacuum cleaner further includes a first separator and a second separator, the first separator being located in a first dust collection chamber and the second separator being located in a second dust collection chamber, with the axis of at least one of the first separator and the second separator being perpendicular to a first direction.

[0013] By aligning the separator's axis perpendicular to the first direction, the size of the vacuum cleaner in that direction can be reduced. Furthermore, when the separator's axis is arranged perpendicular to the first direction, its size in the second direction can be appropriately increased, making it longer in the axial direction, thereby improving the separation efficiency of dust and other dirt from the clean airflow.

[0014] In one possible implementation, a flow channel is provided between the first dust collection chamber and the second dust collection chamber, with one end of the flow channel connected to the outlet of the first dust collection chamber and the other end of the flow channel connected to the connecting part.

[0015] According to the vacuum cleaner provided by this utility model, the flow channel is used to connect two separators, thereby forming a continuous and smooth airflow channel between them, so that the airflow carrying dust and other dirt can flow through the first dust collection chamber and the second dust collection chamber in sequence, and multi-stage separation is achieved through the first separator and the second separator to improve the separation efficiency of dust and clean airflow.

[0016] In one possible implementation, at least a portion of the flow channel is helical.

[0017] Compared to straight pipes, the vacuum cleaner provided by this invention constructs at least a portion of the airflow channel as a spiral tube, which helps to distribute airflow evenly and avoids airflow impact and turbulence that are prone to occur in straight pipes, thereby ensuring that the airflow can smoothly transition from the first separator to the second separator.

[0018] In one possible implementation, the outlet of the first dust collection chamber and the first waste discharge port are located on both sides of the first dust collection chamber in a second direction, which is perpendicular to the first direction.

[0019] Since the outlet of the first dust collection chamber and the first waste discharge port are located on both sides of the first dust collection chamber in the second direction, and one end of the guide channel is connected to the outlet of the first dust collection chamber, the guide channel and the first waste discharge port are located on both sides of the first dust collection chamber in the second direction. When the dirt is separated in the first dust collection chamber, it can fall onto the cover in the second direction. This process can be less disturbed by the guide channel, thus improving the separation efficiency of dust and clean airflow.

[0020] In one possible implementation, the vacuum cleaner further includes an air inlet pipe with its axis parallel to a first direction, the air inlet pipe being located at the bottom of the first dust collection chamber and communicating with the inlet of the first dust collection chamber.

[0021] Since the axis of the air inlet pipe is parallel to the first direction, the external airflow can be drawn in along a straight line and directly introduced into the first dust collection chamber. This method can reduce airflow turning and energy loss, thereby improving suction efficiency.

[0022] In one possible implementation, the vacuum cleaner also includes a handle, which, in a first direction, is located on the side of the motor away from the second dust collection chamber.

[0023] After the vacuum cleaner finishes cleaning, the operator can use the handle to switch the cover from the closed to the open position, opening the first and second waste discharge ports to empty the dirt from the two dust collection chambers. This method makes it easier for the user to apply force, making the dirt removal process more convenient and efficient.

[0024] In one possible implementation, the cover includes a free end and a fixed end, the fixed end being located on the side of the second dust collection chamber away from the first dust collection chamber, and the free end being pivotable about the fixed end. In the closed state, the free end is prevented from pivoting to the side away from the first dust collection chamber; in the open state, the free end is allowed to pivot to the side away from the first dust collection chamber.

[0025] When the cover is closed, the free end is prevented from pivoting away from the second dust collection chamber, ensuring that dirt in both the first and second dust collection chambers does not leak accidentally. When the cover is open, the operator can pivot the free end away from the first dust collection chamber to unload dust and other dirt from the dust collection chamber. According to the vacuum cleaner provided by this invention, the operator can unload dust and debris by opening and closing the cover without disassembling the dust collection chamber, thus improving the convenience of cleaning operations and the user experience.

[0026] In one possible implementation, the projection of the cover plate surface in the first direction is at least partially curved.

[0027] On the one hand, compared with flat plate structures, curved plates have better resistance to deformation; on the other hand, the curved design of the cover plate helps to guide the airflow to rotate around the dust collection chamber, thereby improving the dust-air separation efficiency.

[0041] The embodiments of the present invention will now be described by way of example with reference to the accompanying drawings. It should be understood that there are many ways to implement the present invention, and it should not be construed as being limited to the embodiments described herein. The embodiments described herein are only for a more thorough and clear understanding of the present invention.

[0042] Figures 1 to 4 The present invention provides a vacuum cleaner 100, which includes a motor 10, a dust collection device 20, a separator 50, an air inlet pipe 60, and an exhaust port (not shown). When the motor 10 operates, it creates a negative pressure inside the vacuum cleaner 100, causing airflow located outside the vacuum cleaner 100 to be drawn into the dust collection device 20 through the air inlet pipe 60. When the airflow carrying dust and other contaminants enters the dust collection device 20 and flows through the separator 50, the airflow enters tangentially and generates a rotational motion. During this rotation, the centrifugal force on the dust particles exceeds the air resistance, causing them to separate and be thrown against the inner wall of the dust collection device 20, where they are subsequently collected. This achieves the separation of dust and other contaminants from the clean airflow, and finally, the clean airflow is discharged from the exhaust port.

[0043] refer to Figure 3 and Figure 4The dust collection device 20 includes a first dust collection chamber 21 and a second dust collection chamber 22. The first dust collection chamber 21 has a first discharge port 211, and the second dust collection chamber 22 has a second discharge port 221. The second dust collection chamber 22 is separated from and connected to the first dust collection chamber 21. The first dust collection chamber 21, the second dust collection chamber 22, and the motor 10 are arranged along a first direction. The vacuum cleaner 100 also includes a cover 30, which is configured to close or open the first discharge port 211 and the second discharge port 221. In the closed state, the cover 30 covers the first discharge port 211 and the second discharge port 221, and the length direction of the cover 30 is consistent with the first direction; in the open state, the cover 30 exposes the first discharge port 211 and the second discharge port 221 to allow waste to be discharged.

[0044] When the vacuum cleaner 100 is performing a cleaning operation, the cover 30 is in the closed state, thus closing the first discharge port 211 and the second discharge port 221. At this time, the motor 10 operates and creates a negative pressure inside the vacuum cleaner 100, thereby drawing in external airflow. When the airflow carrying dust and other dirt enters the first dust collection chamber 21 and the second dust collection chamber 22, it is trapped in the first dust collection chamber 21 and the second dust collection chamber 22. After the vacuum cleaner 100 completes the cleaning operation, the cover 30 switches from the closed state to the open state, thereby opening the first discharge port 211 and the second discharge port 221, so that the dust and other dirt in the two dust collection chambers can be discharged together. According to the vacuum cleaner 100 provided by this utility model, the cover 30 is disposed on one side perpendicular to the arrangement direction of the first dust collection chamber 21 and the second dust collection chamber 22. When cleaning the vacuum cleaner 100, the cover 30 can be switched from the closed state to the open state to discharge the dirt, without having to remove the first dust collection chamber 21 and the second dust collection chamber 22 from the main body of the vacuum cleaner 100. This implementation simplifies the operation steps of cleaning the vacuum cleaner 100, makes the operation more convenient, and effectively saves time.

[0045] It should be noted that in the accompanying drawings of this utility model, arrows X+ and X- can be used to indicate the opposite sides of the first direction; arrows Y+ and Y- can be used to indicate the opposite sides of the second direction, and the first direction is perpendicular to the second direction.

[0046] refer to Figures 3 to 6 The first dust collection chamber 21 and the second dust collection chamber 22 are separated by a first partition 40, combined with Figure 5 The first partition 40 is provided with a connecting part 41, through which fluid flows from the first dust collection chamber 21 into the second dust collection chamber 22. In the closed state, the cover 30 is perpendicular to the first partition 40. According to the vacuum cleaner 100 provided by this utility model, after the airflow carrying dust and other dirt is sucked in, it sequentially passes through the first dust collection chamber 21 and the second dust collection chamber 22 (the fluid path is...). Figure 5(As shown by the arrow in the image), in this way, the vacuum cleaner 100 can achieve two-stage separation, thereby improving the separation efficiency of dirt such as dust and cleaning airflow.

[0047] refer to Figure 3 The motor 10 is located on the side of the second dust collection chamber 22 away from the first dust collection chamber 21. The first dust collection chamber 21, the second dust collection chamber 22, and the motor 10 are arranged sequentially along the first direction, which can reduce airflow turning and turbulence, reduce energy loss, and thus improve suction efficiency. In addition, the fact that the motor 10 is located on the side of the second dust collection chamber 22 away from the first dust collection chamber 21 can also reduce the size of the vacuum cleaner 100 in the second direction perpendicular to the first direction, which helps to form a compact layout and a miniaturized design.

[0048] refer to Figure 3 and Figure 4 The separator 50 includes a first separator 51 and a second separator 52. The first separator 51 is located in the first dust collection chamber 21, and the second separator 52 is located in the second dust collection chamber 22. Specifically, the first separator 51 can be used to intercept larger dust particles and collect them in the first dust collection chamber 21, and the second separator 52 can be used to intercept larger dust particles and collect them in the second dust collection chamber 22. In this way, when the airflow carrying dust and other contaminants flows through the first separator 51, most of the larger dust particles are intercepted and collected in the first dust collection chamber 21. Subsequently, the airflow continues to flow to the second separator 52, where finer dust particles are further separated, thereby achieving a graded filtration effect from coarse to fine and improving the cleanliness of the final discharged airflow.

[0049] As one possible implementation, the volume of the first dust collection chamber 21 can be larger than the volume of the second dust collection chamber 22. Since the first dust collection chamber 21 is mainly used to collect larger dust particles, increasing its volume not only provides more ample dust collection space but also significantly extends continuous operation time, reducing the frequency of user cleaning. This implementation helps maintain the stable operation of the vacuum cleaner 100, reduces interruptions caused by mid-operational emptying, and thus effectively improves the equipment's working efficiency and user experience.

[0050] Continue to refer to Figure 3 and Figure 4At least one of the first separator 51 and the second separator 52 has its axis perpendicular to the first direction. This arrangement of perpendicularizing the separator's axis to the first direction reduces the size of the vacuum cleaner 100 in that direction. Furthermore, when the axes of the first separator 51 and the second separator 52 are arranged perpendicular to the first direction, their size in the second direction can be appropriately increased, making them longer in the axial direction, thereby improving the separation efficiency of dust and other dirt from the clean airflow. In another possible implementation, the axes of the first separator 51 and the second separator 52 may be approximately parallel to the first direction.

[0051] It is understood that the shapes of the first separator 51 and the second separator 52 can be implemented in various ways, and this utility model does not impose any particular limitation on them. As an optional embodiment, either the first separator 51 or the second separator 52 can be a conical structure. As another example, either the first separator 51 or the second separator 52 can also be a cylindrical structure.

[0052] refer to Figures 3 to 6 A guide channel 42 is provided between the first dust collection chamber 21 and the second dust collection chamber 22. One end of the guide channel 42 is connected to the outlet 212 of the first dust collection chamber 21, and the other end of the guide channel 42 is connected to the connecting part 41. According to the vacuum cleaner 100 provided by this utility model, the guide channel 42 is used to connect the first separator 51 and the second separator 52, thereby forming a continuous and smooth airflow channel between them. This allows the airflow carrying dust and other dirt to flow sequentially through the first dust collection chamber 21 and the second dust collection chamber 22, and to achieve multi-stage separation through the first separator 51 and the second separator 52, thereby significantly improving the separation efficiency of dust and clean airflow.

[0053] As one possible implementation, refer to Figure 5 and Figure 6 At least a portion of the flow channel 42 is spiral-shaped. Compared to a straight pipe, the vacuum cleaner 100 provided by this utility model constructs at least a portion of the flow channel 42 as a spiral-shaped pipe, which helps to distribute the airflow evenly and avoids the airflow impact and turbulence that are prone to occur in a straight pipe, thereby ensuring that the airflow can smoothly transition from the first separator 51 to the second separator 52.

[0054] refer to Figure 3 and Figure 4The outlet 212 and the first waste discharge port 211 of the first dust collection chamber 21 are located on both sides of the first dust collection chamber 21 in the second direction. Since the outlet 212 and the first waste discharge port 211 of the first dust collection chamber 21 are located on both sides of the first dust collection chamber 21 in the second direction, and one end of the guide channel 42 is connected to the outlet 212 of the first dust collection chamber 21, the guide channel 42 and the first waste discharge port 211 are also located on both sides of the first dust collection chamber 21 in the second direction. In this way, during the dust separation process, the separated contaminants can fall naturally along the second direction and collect on the cover 30, minimizing the interference of the guide channel 42 on the contaminant settling path. This implementation helps maintain smooth airflow and contaminant settling efficiency, thereby improving the separation effect of dust and clean airflow and enhancing the overall system's operational stability.

[0055] Continue to refer to Figure 3 and Figure 4 The axis of the air intake pipe 60 is parallel to the first direction. The air intake pipe 60 is located at the bottom of the first dust collection chamber 21 and is connected to the inlet 213 of the first dust collection chamber 21. Since the axis of the air intake pipe 60 is parallel to the first direction, external airflow can be drawn in in a straight line and directly introduced into the first dust collection chamber 21. This method can reduce airflow turning and energy loss, thereby improving the suction efficiency of the vacuum cleaner 100.

[0056] It should be noted that when the air inlet pipe 60 is located at the bottom of the first dust collection chamber 21, it means that the air inlet pipe 60 is located on the side of the first dust collection chamber 21 that is away from the bottom second dust collection chamber 22 in the first direction.

[0057] refer to Figure 3 The vacuum cleaner 100 also includes a handle 70, which is located on the side of the motor 10 away from the second dust collection chamber 22 in the first direction. After the vacuum cleaner 100 completes the cleaning operation, the operator can hold the handle 70 to switch the cover 30 from the closed state to the open state, thereby opening the first discharge port 211 and the second discharge port 221 to discharge the dirt from the two dust collection chambers. This implementation method makes it easier for the user to apply force, making the dirt cleaning process more convenient and efficient.

[0058] refer to Figure 3 and Figure 4 The cover 30 includes a free end 32 and a fixed end 33. The fixed end 33 is located on the side of the second dust collection chamber 22 away from the first dust collection chamber 21, and the free end 32 is pivotable about the fixed end 33. In the closed state, the free end 32 is prevented from pivoting away from the first dust collection chamber 21; in the open state, the free end 32 is allowed to pivot away from the first dust collection chamber 21.

[0059] refer to Figure 3When the cover 30 is in the closed state, the free end 32 is prevented from pivoting away from the second dust collection chamber 22, which ensures that dirt in the first dust collection chamber 21 and the second dust collection chamber 22 will not leak accidentally. (Reference) Figure 4 When the cover 30 is open, the operator can pivot the free end 32 away from the first dust collection chamber 21, thereby unloading dust and other dirt from the first dust collection chamber 21 and the second dust collection chamber 22. According to the vacuum cleaner 100 provided by this utility model, the operator can unload dust by opening and closing the cover 30 without disassembling the dust collection chamber, thus improving the convenience of cleaning operations and the user experience.

[0060] As one possible implementation, the dust collection device 20 has a mating part 23 at one end away from the motor 10. One end of the mating part 23 is pivotally connected to the dust collection device 20, and the other end has a protrusion 231. The free end 32 has a receiving part 321. When the cover 30 is in the closed state, the protrusion 231 extends into the receiving part 321, and at least a portion of the free end 32 is prevented from pivoting away from the second dust collection chamber 22 by the protrusion 231, ensuring that the cover 30 remains in the closed state.

[0061] It is understood that the connection between the mating part 23 and the free end 32 is not limited to the above-described mechanical interlocking form, and this utility model does not impose any particular limitation on its specific implementation. For example, in some embodiments, the mating part 23 and the free end 32 may each be a magnet with opposite magnetic poles, and the closing and releasing of the cover can be achieved through magnetic attraction.

[0062] refer to Figure 7 and Figure 8 The projection of the plate surface 31 of the cover 30 in the first direction is at least partially arc-shaped.

[0063] On the one hand, compared with a flat plate structure, an arc-shaped plate has better resistance to deformation; on the other hand, the plate surface 31 of the cover 30 is designed to be arc-shaped, which helps to guide the airflow to rotate around the first dust collection chamber 21 and the second dust collection chamber 22, thereby improving the dust-air separation efficiency.

[0064] It should be understood that there are multiple ways to implement the vacuum cleaner 100 of this utility model, and it should not be construed as being limited to the embodiments described above. The following, in conjunction with... Figure 9 The following are illustrative examples of variations of this utility model. It should be noted that the foregoing embodiments and the following variations share some common elements. In the following variations, these elements will use the same reference numerals as in the foregoing embodiments to omit repeated descriptions.

[0065] refer to Figure 9The motor 10a of the vacuum cleaner 100a is located on the side of the first dust collection chamber 21 away from the second dust collection chamber 22. Thus, the motor 10a is connected to the first dust collection chamber 21 via a pipe extending in a second direction. To remove dirt from the dust collection device 20, the dust collection device 20 is first removed from the body of the vacuum cleaner 100a to eliminate interference between the pipe between the motor 10a and the first dust collection chamber 21 and the cover 30. When the cover 30 is switched from the closed state to the open state, the first discharge port 211 and the second discharge port 221 can be opened, thereby discharging dust and other dirt.

[0066] It should be understood that the term "comprising" and its variations used in this utility model are open-ended, meaning "including but not limited to". The term "according to" means "at least in part according to". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least another embodiment".

[0067] It should be understood that although terms such as "first" or "second" may be used in this invention to describe various elements (such as the first dust collection chamber and the second dust collection chamber), these elements are not defined by these terms, which are only used to distinguish one element from another.
