Description

Technical Field

[0001] This application relates to the field of home appliance technology, and in particular to a dust collection component and a vacuum cleaner. Background Technology

[0002] Traditional vacuum cleaners mostly use single-cone separation technology, which has limited separation efficiency, especially in filtering fine dust. While some multi-cone separation technologies exist, their single airflow path results in lower separation efficiency. Utility Model Content

[0003] This application provides a dust collection component and a vacuum cleaner to solve the problem of low separation efficiency in vacuum cleaners.

[0004] On one hand, this application provides a dust collection assembly, including a dust collection structure, a suction structure, a separation structure, a drive structure, and a shielding frame. The dust collection structure is suitable for filtering and collecting dust. The suction structure is connected to the dust collection structure and is suitable for sucking up the air after the dust has been separated. The separation structure is rotatably configured and has multiple separation channels suitable for separating dust. The separation structure has an air outlet and a dust outlet for each separation channel. The air outlet is connected to the suction structure, and the dust outlet is connected to the dust collection structure. The output end of the drive structure is connected to the separation structure and is suitable for driving the separation structure to rotate. The shielding frame is located between the suction structure and the separation structure. When the drive structure drives the separation structure to rotate, a portion of the shielding frame is suitable for blocking at least part of the air outlet to control the number of air outlets of the separation structure connected to the suction structure.

[0005] In one possible implementation, the shielding frame includes a frame and a first shielding member disposed on the frame. The first shielding member is used to cover the air outlet. When the first shielding member covers the air outlet, it is located between the air outlet and the suction structure. Along the rotation axis direction of the separation structure, the projection of the first shielding member onto the air outlet completely covers the opening of the air outlet.

[0006] In one feasible approach, the air outlets of multiple separation channels are arranged at equal intervals around the rotation axis of the separation structure, and along the rotation axis of the separation structure, the projection of the first shielding member toward the air outlet is located between two adjacent air outlets.

[0007] In one feasible embodiment, the frame is a ring structure, with the central axis of the frame coinciding with the rotation axis of the separation structure. One end of the first shield is connected to the inner ring wall of the frame, and the other end of the first shield extends toward the rotation axis of the separation structure.

[0008] In one feasible method, the first shielding member is provided in multiple ways, and the multiple first shielding members are arranged at equal intervals around the rotation axis of the separation structure. Along the rotation axis of the separation structure, the air outlet is located between the projections of two adjacent first shielding members facing the air outlet.

[0009] In one feasible manner, the separation channel includes at least a plurality of first separation channels arranged circumferentially around the axis of rotation of the separation structure, with one end of a first shield connected to a shielding frame and the other end extending toward the axis of rotation of the separation structure.

[0010] In one possible implementation, the separation channel further includes multiple second separation channels, which are arranged circumferentially around the rotation axis of the separation structure. The shielding frame also includes a second shielding member connected to the first shielding member. The second shielding member covers the air outlet of the second separation channel. The second shielding member is also provided with multiple through holes, which are spaced apart around the rotation axis of the separation structure. When the separation structure rotates, the through holes can connect to the air outlet of the second separation channel.

[0011] In one feasible embodiment, the separation structure includes a first separation member and a separation end cap. The first separation member has a first receiving cavity, and a dust outlet is formed at one end of the first separation member and communicates with the first receiving cavity. A portion of the structure of the separation end cap covers the end of the first receiving cavity away from the dust outlet. The separation end cap has a first air outlet at the position corresponding to each first receiving cavity, and the first air outlets are respectively communicated with the corresponding first receiving cavities.

[0012] In one feasible embodiment, the split end cap includes an end cap body and an air outlet protruding from one end of the end cap body. The air outlet is adapted to be inserted into a first receiving cavity, and an air outlet channel is provided in the air outlet, which connects the first receiving cavity and a first air outlet.

[0013] In one feasible embodiment, the peripheral wall of the first separator is further provided with a first air inlet, which is connected to the first receiving cavity, and the opening direction of the first air inlet is tangent to the inner wall of the first receiving cavity.

[0014] In one possible implementation, the separation structure further includes a second separation member, the interior of which is provided with a second receiving cavity. One end of the second receiving cavity is opened to form a dust outlet. A portion of the separation end cap is provided on the end of the second receiving cavity away from the dust outlet. The separation end cap forms an air outlet corresponding to the position of each second receiving cavity, and the air outlet is connected to the corresponding second receiving cavity.

[0015] In one possible embodiment, the peripheral wall of the second separator is further provided with a second air inlet, which is connected to the second receiving cavity, and the opening direction of the second air inlet is tangent to the inner wall of the second receiving cavity.

[0016] In one feasible approach, a sensor is provided on the blocking component, and a sensing element is provided on the separating structure. During the rotation of the separating structure, the sensing element can be aligned with the sensing part of the sensor.

[0017] In one possible implementation, the separation structure further includes a separation bracket, and the drive structure includes a drive element and a drive shaft. The drive shaft is connected to the output end of the drive element, the drive element is connected to the shield, and the drive shaft is also connected to the separation bracket. The drive element drives the separation bracket to rotate via the drive shaft.

[0018] In one feasible embodiment, the dust collection structure includes a dust collection shell and a dust collection box. The dust collection shell is provided with a first dust collection chamber, and the dust collection box is located in the first dust collection chamber. The dust collection box is provided with a filter element. The filter element and the inner wall of the dust collection shell surround a separation space. The flow channel and the separation space are connected through the filter element, and the filter element is suitable for filtering dust from the air in the separation space.

[0019] In one possible embodiment, the dust collection box includes a dust collection cylinder, a second dust collection chamber is provided inside the dust collection cylinder, a dust outlet is connected to the second dust collection chamber, a transition channel is formed between the filter element and the dust collection cylinder, and the transition channel is connected to the flow channel.

[0020] On the other hand, this application provides a vacuum cleaner, including a vacuum body and the aforementioned dust collection component.

[0021] The dust collection component of this application, by setting up a shielding component, can selectively block part of the air outlet according to the suction power of the suction structure or the amount of dust, thereby adjusting the number of air outlets connected to the suction structure. When the suction structure is running at a lower power, blocking the air outlets by the shielding component can reduce the number of air outlets connected to the suction structure, thereby reducing the airflow space, increasing the airflow speed, and increasing the dust separation efficiency. When there is a lot of dust mixed in the air to be separated, there is no need to increase the power of the suction structure; simply blocking the air outlets by the shielding component can reduce the number of air outlets connected to the suction structure, thereby reducing the airflow space, increasing the airflow speed, and increasing the dust separation efficiency. Therefore, the dust collection component of this application drives the separation structure to rotate through the driving structure, which can be used in conjunction with the shielding component to specifically block the air outlet, making it easy to adjust the space for airflow. This not only makes the airflow path variable, but also helps to increase the airflow speed. The increased airflow speed can increase the separation efficiency of dust. Moreover, for air with a large amount of dust, there is no need to increase the power of the suction structure to ensure the separation efficiency, which helps to reduce power consumption.

[0040] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0041] Vacuum cleaners using this technology utilize the rotation and flow of air within a separation channel. Under centrifugal force, dust and air are separated, and the air, now free of dust, is released into the external environment through the vacuum cleaner's suction mechanism. The speed of the airflow within the separation channel affects the separation intensity of the dust; the faster the airflow, the higher the separation intensity, the better the separation effect, and the higher the separation efficiency. The power of the suction mechanism determines the suction force; lower power results in lower suction force, and higher power results in higher suction force. The separation channel typically has an outlet. The suction mechanism reduces the pressure at the outlet, creating negative pressure to draw air out of the separation channel. The path of the airflow from inside the separation channel to the outlet is the airflow path for the suction. In related technologies, with a fixed number of air outlets, if the suction structure has low power, the airflow velocity during suction is much lower than when the suction power is higher. This slower airflow velocity affects the effectiveness and efficiency of dust separation. Furthermore, if there is a large amount of dust in the air, with a fixed number of air outlets, the suction speed at higher power is greater than at lower power. Therefore, when separating dust from air with a high dust concentration, it is often necessary to operate the suction structure at a higher power, resulting in higher power consumption. Thus, in related technologies, with a fixed number of air outlets and a constant airflow path, when the suction structure uses lower power, the larger space for airflow results in a significantly lower airflow velocity compared to when the suction structure uses higher power. Therefore, these related technologies also suffer from the problem of not being able to flexibly adjust the airflow velocity.

[0042] To address the aforementioned issues, this application provides a dust collection component with a shielding frame inside. This frame can cover part of the air outlet according to actual conditions, thereby reducing the airflow path. Even when the suction structure is operating at low power, the airflow speed can still be guaranteed. Furthermore, when there is a large amount of dust in the air, the airflow speed can be increased without increasing the power of the suction structure, ensuring the efficiency of dust separation.

[0043] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0044] See Figure 1As shown, this application provides a dust collection component 100 and a vacuum cleaner using the dust collection component 100. The vacuum cleaner includes a vacuum body 200, which is mainly used for vacuuming. It mainly includes a handle 201 and a vacuum component 202 connected to the handle 201. The handle 201 is for holding by hand, and the vacuum component 202 is for sucking up dust from the ground. Understandably, when the vacuuming assembly 202 sucks up dust from the ground, it is often accompanied by airflow. The vacuuming assembly 202 has an airflow space inside, and one end of this space is open to be aimed at the dust on the ground so that the dust can enter the internal space of the vacuuming assembly 202 through the opening. The other end of the airflow space inside the vacuuming assembly 202 is connected to the dust collection assembly 100. At this time, the airflow mixed with dust can enter the dust collection assembly 100 from the vacuuming assembly 202. The dust collection assembly 100 can filter the airflow mixed with dust, and the filtered airflow can flow out again from the dust collection assembly 100. The filtered dust will be collected inside the dust collection assembly 100.

[0045] See Figures 2 to 8 As shown, the dust collection assembly 100 of this application specifically includes a dust collection structure 10, a suction structure 20, a separation structure 30, a drive structure 40, and a shielding frame 50. The dust collection structure 10 can be used to collect dust. In this embodiment, the dust collection structure 10 can also be used to filter larger dust particles in the air; the specific filtration structure and method will be described below. The separation structure 30 is rotatably disposed within the dust collection structure 10. The separation structure 30 is provided with multiple separation channels suitable for separating dust. Air mixed with dust, delivered by the suction assembly 202 to the dust collection structure 10, can enter the separation channels of the separation structure 30. When the air flows within the separation channels, centrifugal force can separate the dust and air. The separation structure 30 is provided with an air outlet 323 and a dust outlet 39 corresponding to each separation channel. Both the air outlet 323 and the dust outlet 39 are connected to the separation channel. Furthermore, the air outlet 323 is also connected to the suction structure 20, and the dust outlet 39 is also connected to the dust collection structure 10. The separation structure 30 can separate air and dust. The separated dust will enter the dust collection structure 10 from the dust outlet 39, and the air after the dust separation will be sucked out of the dust collection component 100 by the suction structure 20.

[0046] The suction structure 20 of this application mainly includes a suction base 21 and a suction device 22 disposed inside the suction base 21. The suction base 21 is connected to the dust collection structure 10, and the connection between the suction base 21 and the dust collection structure 10 is sealed to ensure stable air pressure inside the suction structure 20. The suction base 21 has a hollow shell structure. The suction device 22 is located inside the suction base 21. The suction part of the suction device 22 is located near the separation structure 30, and the end of the suction base 21 near the separation structure 30 is provided with at least one communication channel for communicating with the air outlet 323. The suction device 22 has the function of generating negative pressure, so that the pressure at the external end near the air outlet 323 is less than the pressure inside the separation channel, thereby allowing the air in the separation channel to be drawn out. The drawn-out air can enter the interior of the suction base 21 through the communication channel and then be discharged. The suction device 22 of this application can be any structure in the prior art that can generate negative pressure, such as a combination of axial flow fan, motor and spiral blades, etc., which will not be described in detail here.

[0047] The output end of the drive structure 40 is connected to the separation structure 30, and the drive structure 40 is adapted to drive the separation structure 30 to rotate.

[0048] The shield 50 can be connected to the suction structure 20 or the dust collection structure 10. The shield 50 is located between the suction structure 20 and the separation structure 30. Along the rotation axis of the separation structure 30, the projection of a portion of the shield 50 in that direction lies on the rotation path of the air outlet 323 as the separation structure 30 rotates. That is, when the separation structure 30 rotates, the air outlet 323 can be directly facing this portion of the shield 50. At this time, this portion of the structure is located between the air outlet 323 and the suction structure 20, and is used to shield the air outlet 323, restricting the suction structure 20 from drawing air from the shielded air outlet 323. When the suction structure 20 draws air from the separation channel, the drawn air flows out from the air outlet 323. When the drive structure 40 drives the separation structure 30 to rotate, part of the shielding frame 50 can block at least part of the air outlet 323. Blocking at least part of the air outlet 323 means that only one air outlet 323 can be blocked, or two or more air outlets 323 can be blocked. By blocking the air outlets 323 by the shielding frame 50, the number of air outlets 323 connected to the suction structure 20 by the separation structure 30 can be controlled. The air inside the separation channel with the air outlets 323 blocked will not be drawn out by the suction structure 20.

[0049] The dust collection assembly 100 of this application has a shielding frame 50 between the suction structure 20 and the separation structure 30. The separation structure 30 is driven to rotate by the drive structure 40. Part of the structure of the shielding frame 50 can cover part of the air outlet 323 of the separation structure 30, so that the suction structure 20 cannot suck up the air in the separation channel of the covered air outlet 323. In this way, the number of air outlets 323 connected to the suction structure 20 can be controlled, thereby controlling the number of air flow paths and making the air flow path after dust separation flexible and varied.

[0050] This application, by setting up a shielding component, can selectively shield part of the air outlet 323 according to the suction power of the suction structure 20 or according to the amount of dust, thereby adjusting the number of air outlets 323 connected to the suction structure 20. When the suction structure 20 operates at a lower power, shielding the air outlets 323 reduces the number of air outlets 323 connected to the suction structure 20, thereby reducing the airflow space, increasing the airflow speed, and increasing the dust separation efficiency. When there is a lot of dust mixed in the air to be separated, there is no need to increase the power of the suction structure 20; simply shielding the air outlets 323 reduces the number of air outlets 323 connected to the suction structure 20, thereby reducing the airflow space, increasing the airflow speed, and increasing the dust separation efficiency. Therefore, the dust collection component 100 of this application drives the separation structure 30 to rotate through the drive structure 40, which can work with the shielding component to specifically block the air outlet 323, making it easy to adjust the space for airflow. This not only makes the airflow path variable, but also helps to increase the airflow speed. The increased airflow speed can increase the separation efficiency of dust. Moreover, for air with a large amount of dust, there is no need to increase the power of the suction structure 20 to ensure the separation efficiency, which helps to reduce power consumption.

[0051] See Figure 3As shown, in some feasible implementations, the shielding frame 50 includes a frame 51 and a first shielding member 52 disposed on the frame 51. The first shielding member 52 is connected to the frame 51. The first shielding member 52 can be integrally formed with the frame 51, or the first shielding member 52 can be connected to the frame 51 by means of bonding, welding, etc., or the first shielding member 52 can also be connected to the frame 51 by a snap-fit ​​structure, a fastening structure, or screws. In this application, the frame 51 is connected to the suction base 21 of the suction structure 20, specifically by a snap-fit ​​structure, a fastening structure, or screws. When the frame 51 is connected to the suction base 21 and the suction base 21 is connected to the dust collection structure 10, the first shielding member 52 is close to the air outlet 323, and one end face of the first shielding member 52 faces the separation structure 30. This end face facing the separation structure 30 is used to cover the air outlet 323. When the separation structure 30 rotates, part of the air outlet 323 can rotate to the position of the first shield 52, and the end face of the first shield 52 facing the air outlet 323 can be used to cover the corresponding air outlet 323. It should be noted that for the end face of the first shield 52 facing the air outlet 323 to cover the air outlet 323, the size of the end face of the first shield 52 facing the air outlet 323 must be greater than or equal to the diameter of the air outlet 323. That is, the area of ​​the orthographic projection of the end face of the first shield 52 facing the air outlet 323 in the direction facing the air outlet 323 must be greater than or equal to the diameter of the air outlet 323, so that the first shield 52 can completely cover the air outlet 323.

[0052] Alternatively, in some embodiments, the size of the end face of the first shield 52 used to shield the air outlet 323 is smaller than the diameter of the air outlet 323. When the air outlet 323 is rotated to face the end face of the first shield 52 used to shield, the air outlet 323 cannot be completely covered, but only a part of the opening of the air outlet 323 can be covered. This can also reduce the overall air flow space and increase the air flow speed.

[0053] See Figures 3 to 8 As shown, in some embodiments, multiple separation channels are arranged at equal intervals around the axis of the separation structure 30, and the air outlets 323 of the separation channels are arranged at equal intervals around the axis of the separation structure 30. Figure 8 The dashed line H in the figure represents the axis of rotation of the separation structure 30. By arranging the air outlets 323 of multiple separation channels at equal intervals around the axis of rotation of the separation structure 30, when the first blocking member 52 blocks adjacent air outlets 323, the driving structure 40 drives the separation structure 30 to rotate at equal angles. This ensures that when an air outlet 323 needs to be blocked, the angle of rotation of the separation structure 30 is uniform and regular, which helps to reduce the difficulty of controlling the rotation of the separation structure 30.

[0054] It should be noted that the size of the end face of the first shield 52 facing the air outlet 323 is less than or equal to the distance between two adjacent air outlets 323. This ensures that when the first shield 52 is located between two adjacent air outlets 323, it will not cover the air outlet 323, thus ensuring that each air outlet 323 can be fully connected to the suction structure 20.

[0055] In some embodiments, the frame 51 of this application has a ring structure. When the frame 51 is connected to the suction base 21, the center of the ring of the frame 51 coincides with the axis of rotation of the separation structure 30. One end of the first shielding member 52 is connected to the inner ring wall of the frame 51, and the other end of the first shielding member 52 extends toward the axis of rotation of the separation structure 30. In this way, the extension direction of the first shielding member 52 can be parallel to the radial direction when the separation channel is arranged circumferentially. When the separation structure 30 is rotated, it is beneficial to cover the air outlet 323 of the separation channel.

[0056] It should be noted that when multiple separation channels are set, some of the separation channels can be grouped together, and multiple separation channels can be divided into multiple groups. Separation channels within the same group are spaced apart around the rotation axis of the separation structure 30, and multiple groups of separation channels are spaced apart around the rotation axis of the separation structure 30. It is worth mentioning that the distance between each group of separation channels and the rotation axis of the separation structure 30 can be all equal, all unequal, or partially equal and partially unequal.

[0057] In some embodiments, one or more first blocking members 52 may be provided. In this application, multiple first blocking members 52 are provided. When the separation structure 30 is driven to rotate, multiple first blocking members 52 can cooperate to cover multiple air outlets 323. Each first blocking member 52 can cover part of the air outlet 323. In this way, by increasing the number of first blocking members 52, the number of air outlets 323 that are covered at the same time can be increased, which can better reduce the flow space during air flow and facilitate faster air flow.

[0058] It should be noted that when multiple first shielding members 52 are provided, the multiple first shielding members 52 are arranged circumferentially around the rotation axis of the separation structure 30. At this time, the distance between two adjacent first shielding members 52 can be equal or unequal. This application takes the arrangement of multiple first shielding members 52 at equal intervals around the rotation axis of the separation structure 30 as an example for explanation. When the distance between two adjacent first shielding members 52 is equal, the distance between two adjacent first shielding members 52 is greater than or equal to the diameter of the air outlet 323. In this way, when the air outlet 323 is located between any two adjacent first shielding members 52, it will not be blocked by the first shielding members 52, ensuring that the air outlet 323 can be fully connected to the suction structure 20.

[0059] See Figures 3 to 8As shown, in some feasible implementations, when the separation structure 30 has multiple separation channels, the multiple separation channels can be arranged in various ways on the separation structure 30. The arrangement of the separation channels on the separation structure 30 can be intuitively reflected by the arrangement of the air outlet 323 on the separation structure 30. For example, in this application, the separation channels include at least multiple first separation channels 36 and multiple second separation channels 37. The multiple first separation channels 36 and multiple second separation channels 37 are arranged circumferentially around the rotation axis of the separation structure 30. The radial dimension of the circumferential arrangement of the first separation channels 36 is greater than the radial dimension of the circumferential arrangement of the second separation channels 37. In this way, the first separation channels 36 and the second separation channels 37 can be arranged in two layers, inner and outer, on the separation structure 30.

[0060] It should be noted that the air outlet 323 of the first separation channel 36 is designated as the first air outlet 3231, and the air outlet 323 of the second separation channel 37 is designated as the second air outlet 3232. Around the circumferential direction of the axis of rotation of the separation structure 30, the air outlet 323 of any second separation channel 37 is located between two adjacent air outlets 323 of the first separation channel 36. This facilitates the separate blocking of the air outlets 323 of the first separation channel 36 and the second separation channel 37, and helps control the number of air outlets 323 connected to the suction structure 20. By controlling the number of times the first air outlet 3231 and the second air outlet 3232 are blocked, the number of air outlets 323 connected to the suction structure 20 when the first air outlet 3231 is blocked differs from the number of air outlets 323 connected to the suction structure 20 when the second air outlet 3232 is blocked. This creates a graded adjustment function, increases the control range of the air outlets 323 connected to the suction structure 20, and improves flexibility. Furthermore, by dividing the air outlets 323 into inner and outer layers, the airflow velocity in the first separation channel 36 and the second separation channel 37 can be adjusted according to actual conditions. When the first air outlet 3231 is blocked, the airflow velocity in the first separation channel 36 increases; when the second air outlet 3232 is blocked, the airflow velocity in the second separation channel 37 increases, which is beneficial for controlling the airflow velocity within the separation channels.

[0061] In some implementations, the first shielding member 52 can be used to shield the second air outlet 3232. Since the second air outlet 3232 is located between two adjacent first air outlets 3231, when the first shielding member 52 is located between two adjacent first separation channels 36, it can cover the second air outlet 3232. It should be noted that when the first shielding member 52 shields the second air outlet, the number of outlets shielded can be set to be less than the number shielded when shielding the first air outlets. By switching between shielding the first air outlets 3231 and the second air outlet 3232, different numbers of air outlets 323 can be shielded at once, corresponding to different power adjustments of the suction structure 20. This allows for more flexible adjustment of the airflow path and speed.

[0062] To ensure that the number of second air outlets 3232 blocked by the first shielding member 52 is less than the number blocked by the first air outlet 3231, the position of the second air outlets 3232 can be set according to the arrangement of the first shielding member 52. For example, when the separation structure 30 rotates to the position where the first shielding member 52 is located between two adjacent first air outlets 3231, some of the second air outlets 3232 can be set directly opposite the second shielding member 53, and the other part of the second air outlets 3232 can be set between two adjacent second shielding members 53. At this time, the second air outlets 3232 directly opposite the second shielding member 53 are blocked, while the second air outlets 3232 located between two adjacent second shielding members 53 are not blocked. By setting the number of second air outlets 3232 directly opposite the first shielding member 52, the number of second air outlets 3232 that are blocked can be controlled.

[0063] In some implementations, this application can also cover the second air outlet 3232 by setting an additional shielding component. For example, the shielding frame 50 also includes a second shielding component 53, which is located at the center of the frame 51 and connected to the end of the first shielding component 52 away from the frame 51. The second shielding component 53 can be circular, square, or other shapes. In the embodiment of this application, the second shielding component 53 is disc-shaped, and the center of the second shielding component 53 coincides with the annular center of the frame 51. When the frame 51 is connected to the suction base 21, the second shielding component 53 can cover the end face of the air outlet 323 of the second separation channel 37, and can cover all the second air outlets 3232. The second shielding member 53 of this application is also provided with a plurality of through holes 531. The plurality of through holes 531 are spaced apart around the rotation axis of the separation structure 30. Along the rotation axis direction of the separation structure 30, the projections of the plurality of through holes 531 are all located on the rotation path of the second air outlet 3232 when the separation structure 30 rotates. Thus, when the second air outlet 3232 rotates with the separation structure 30, it can be directly opposite the plurality of through holes 531 respectively. At this time, the second air outlet 3232 can be connected to the suction structure 20 through the second through holes 531. When the separation structure 30 rotates to the point where the second air outlet 3232 and the through holes 531 are misaligned, the second shielding member 53 can cover the second air outlet 3232.

[0064] In this embodiment, the cooperation of the first shielding member 52 and the second shielding member 53 can block different numbers of air outlets 323, thereby changing the number of blocked air outlets 323 according to the amount of dust in the air and the power of the suction structure 20, so as to ensure the efficiency of dust separation. For example, see Figures 4 to 6 As shown, there are ten first air outlets 3231, four second air outlets 3232, and five first shielding components 52. Figure 4 This is the state when neither the first air outlet 3231 nor the second air outlet 3232 is blocked. When the amount of dust is large or the power of the suction structure 20 is very low, a large number of air outlets 323 need to be covered. In this case, by rotating the separation structure 30, part of the first air outlet 3231 can be rotated to the first blocking member 52, and the second air outlet 3232 can be rotated to the through hole 531 of the second blocking member 53. Figure 5 As shown, each of the five first shielding members 52 blocks one first air outlet 3231, thus blocking all five first air outlets 3231. The four second air outlets 3232 remain unblocked. This reduces the path of air intake by the suction structure 20, and increases the airflow speed from the remaining unblocked outlets 323. When the dust level is moderate and the power of the suction structure 20 is low, the separation structure 30 is rotated until the first shielding member 52 is positioned between two adjacent first air outlets 3231, and only two of the four second air outlets 3232 are directly opposite the through hole 531. Figure 6 As shown, only the two second air outlets 3232 are blocked at this time.

[0065] certainly, Figure 5 and Figure 6 The two shown are just two of the many ways of blocking. You can also block part of the first air outlet 3231 and part of the second air outlet 3232 by rotating the separation structure 30. This can increase the number of air outlets 323 that are blocked. This will not be described in detail here.

[0066] Therefore, by rotating the separation structure 30 at different angles, the first air outlet 3231 and / or the second air outlet 3232 can be blocked, thereby adjusting the number of the first air outlet 3231 and the second air outlet 3232 that are blocked, so as to adjust the airflow speed according to the amount of dust and the power of the suction structure 20, and ensure dust separation efficiency.

[0067] It should be noted that the blocking component is also equipped with a sensor 54, and the separating structure 30 is equipped with a sensor 38. The sensor 38 and the sensor 54 work together for positioning. When the separating structure 30 rotates, the sensor 38 can be directly aligned with the sensing part of the sensor 54. At this time, the sensor 54 can detect the sensor 38, and the position of the separating structure 30 at this time can be recorded as the initial position. The angle of the separating structure 30 at this position is 0°. The rotation angle of the separating structure 30 is subsequently recorded based on this angle. This makes it easier to rotate the separating structure 30 to its final position. Figure 5 and Figure 6 The location shown.

[0068] The structure of the sensing element 54 and sensing element 38 in this application is not specifically limited. The sensing element 54 can be, for example, a Hall plate, and the sensing element 38 can be, for example, a magnet.

[0069] See Figure 2 , Figures 8 to 10 As shown, in some feasible implementations, the separation structure 30 includes a first separation member 34 and a separation end cap 32. The first separation member 34 has a first receiving cavity 342. One end of the first separation member 34 is located near the suction structure 20, and the other end extends toward the dust collection structure 10. A dust outlet 39 is formed at the end of the first separation member 34 near the dust collection structure 10, and the dust outlet 39 is connected to the first receiving cavity 342. A portion of the separation end cap 32 is provided on the end of the first receiving cavity 342 away from the dust outlet 39. The separation end cap 32 has a first air outlet 3231 at the position corresponding to each first receiving cavity 342, and the first air outlet 3231 is connected to the corresponding first receiving cavity 342.

[0070] The first receiving cavity 342 is used to form the first separation channel 36. In this embodiment, the peripheral wall of the first separating member 34 is also provided with a first air inlet 341. The first air inlet 341 is located at the end of the first separating member 34 away from the dust outlet 39. The first air inlet 341 is connected to the first receiving cavity 342. The first air inlet 341 is connected to the air inlet 112 of the dust collection structure 10. The air sucked into the dust collection structure 10 by the dust suction assembly 202 can enter the first receiving cavity 342 from the first air inlet 341. After the dust is separated in the first receiving cavity 342, the air can flow out from the first air outlet 3231.

[0071] It should be noted that the inner wall of the first receiving cavity 342 in this application is curved, and the specific shape can be determined according to the shape of the first receiving cavity 342. For example, the shape of the first receiving cavity 342 in this application is conical, or the first receiving cavity 342 is a combination of cylindrical and conical shapes. When the shape of the first receiving cavity 342 is conical, the larger end of the cone is located near the suction structure 20, and the smaller end is located near the dust collection structure 10, with the dust outlet 39 connected to the smaller end of the cone. When the shape of the first receiving cavity 342 is a combination of cylindrical and conical shapes, the size of the cylinder is the same as the size of the larger end of the cone, one end of the cylinder is connected to the larger end of the cone, and one end of the cylinder is near the suction structure 20, while the smaller end of the cone is near the dust collection structure 10. The inner wall of the first receiving cavity 342 is made into a curved surface. When air enters the first receiving cavity 342 from the first air inlet 341, the air can flow along the curved wall of the first receiving cavity 342, which is conducive to the air rotating and flowing in the first receiving cavity 342. In this way, the dust in the air can be separated under the action of centrifugal force. The separated dust falls along the inner wall of the first receiving cavity 342 to the dust outlet 39 and enters the dust collection structure 10 from the dust outlet 39.

[0072] It should also be noted that the opening direction of the first air inlet 341 in this application is tangent to the inner wall of the first receiving cavity 342. In this way, when air enters the first receiving cavity 342 through the first air inlet 341, the direction of airflow is tangent to the inner wall of the first receiving cavity 342, which is conducive to the air rotating and flowing within the first receiving cavity 342 after entering it, and facilitates the separation of dust from the air by centrifugal force.

[0073] See Figure 11 and Figure 12As shown, in some possible implementations, the separating end cap 32 includes an end cap body 321 and an air outlet 322 protruding from one end of the end cap body 321. The end cap body 321 is used to overlap the first separating member 34. When the end cap body 321 overlaps the end cap body 321, the air outlet 322 can be inserted into the first receiving cavity 342. It should be noted that the first separating member 34 is also provided with an opening communicating with the first receiving cavity 342 at the end away from the dust outlet 39. The air outlet 322 extends into the first receiving cavity 342 through the opening.

[0074] The first air outlet 3231 of this application is disposed on the end cover body 321, and the position of the first air outlet 3231 corresponds to the opening position of the first receiving cavity 342 on the first separating member 34. The air outlet member 322 of this application is disposed at the position of each first air outlet 3231 and is located on the side of the end cover body 321 facing the first separating member 34. An air outlet channel 3221 is provided in the air outlet member 322, the air outlet channel 3221 passes through the air outlet member 322, one end of the air outlet channel 3221 is connected to the first receiving cavity 342, and the other end of the air outlet channel 3221 is connected to the first air outlet 3231. The air separated from the dust in the first receiving cavity 342 can flow out of the first receiving cavity 342 through the air outlet channel 3221. By setting an air outlet 322, which protrudes from the end cap body 321, the air outlet channel 3221 of the air outlet 322 can serve as an extension of the first air outlet 3231, so that the connection position between the first air outlet 3231 and the first receiving cavity 342 is located at the connection position between the air outlet channel 3221 and the first receiving cavity 342. In this way, the connection position between the first air outlet 3231 and the first receiving cavity 342 is closer to the dust outlet 39 relative to the position of the first air inlet 341. After the air enters the first receiving cavity 342 from the first air inlet 341, it first completes the rotation flow to separate the dust. The air after the dust separation is then extracted by the suction structure 20 through the air outlet channel 3221, ensuring that the dust in the extracted air can be sufficiently separated.

[0075] See Figures 8 to 12 As shown, in some feasible embodiments, the separation structure 30 further includes a second separation member 35. The second separation member 35 has a second receiving cavity 352 inside, which forms a second separation channel 37. One end of the second separation member 35 is close to the suction structure 20, and the other end extends towards the dust collection structure 10. A dust outlet 39 is provided at the end of the second separation member 35 near the dust collection structure 10, and the dust outlet 39 communicates with the second receiving cavity 352. A portion of the separation end cap 32 is provided on the end of the second separation member 35 away from the dust outlet 39. The separation end cap 32 forms a second air outlet 3232 at the position corresponding to each second receiving cavity 352, and the second air outlet 3232 communicates with the corresponding second receiving cavity 352.

[0076] The shape of the second receiving cavity 352 is similar to that of the first receiving cavity 342, and can be referred to the first receiving cavity 342 for details, which will not be repeated here. The peripheral wall of the second separating member 35 is also provided with a second air inlet 351, which connects to the second receiving cavity 352, allowing air to enter the second receiving cavity 352 through the second air inlet 351. The opening direction of the second air inlet 351 is tangent to the inner wall of the second receiving cavity 352, so that after the air enters the second receiving cavity 352 through the second air inlet 351, the air can rotate and flow along the inner wall of the second receiving cavity 352. This facilitates the separation of dust from the air under the action of centrifugal force.

[0077] It should be noted that the second receiving cavity 352 is opened at one end near the second air inlet 351. The end cover body 321 is provided with an air outlet 322 protruding from the end of the second receiving cavity 352 at the position corresponding to the second air inlet 351. The air outlet 322 is inserted into the second receiving cavity 352. An air outlet channel 3221 is provided in the air outlet 322. One end of the air outlet channel 3221 away from the end cover body 321 is connected to the second receiving cavity 352, and the other end of the air outlet channel 3221 is connected to the second air inlet 351.

[0078] In some implementations, multiple first separation channels 36 and second separation channels 37 are provided to realize the separation structure 30. Multiple first separation members 34 and multiple second separation members 35 are provided in this application. The multiple first separation members 34 are arranged circumferentially around the axis of rotation of the separation structure 30, and the multiple second separation members 35 are also arranged circumferentially around the axis of rotation of the separation structure 30. Furthermore, the radial arrangement dimension of the multiple first separation members 34 is larger than the radial arrangement dimension of the multiple second separation members 35. At this time, multiple air outlet members 322 are also provided on the end cap body 321, and one air outlet member 322 is inserted into each first receiving cavity 342 and each second receiving cavity 352.

[0079] In some feasible implementations, the separation structure 30 further includes a separation bracket 33, to which the first separation member 34, the second separation member 35, and the separation end cap 32 are all connected. Specifically, the separation bracket 33 includes a separation top plate 331 and a separation base 332, which are spaced apart and can be connected together by a connecting structure.

[0080] The separation top plate 331 and separation base 332 in this application are generally circular in shape, and the centers of the two circles coincide in the interval direction between them. The centers of the two separation top plates 331 and the center of the separation base 332 are connected by a connecting structure such as a connecting rod or a connecting column. The driving component 42 is located on the side of the shield 50 facing away from the separation structure 30. The driving shaft 41, which is connected to the output end of the driving component 42, passes through the shield 50 and is connected to the center position of the separation top plate 331. Alternatively, the driving shaft 41 can extend towards the separation base 332 after being connected to the separation top plate 331 and be connected to the separation base 332 at the same time.

[0081] In this application, a plurality of first separating members 34 and a plurality of second separating members 35 are arranged at intervals around the drive shaft 41 between the separating top plate 331 and the separating base 332. One end of the first separating member 34 with a first air inlet 341 and one end of the second separating member 35 with a second air inlet 351 are both connected to the separating top plate 331. One end of the first separating member 34 and the second separating member 35 with a dust outlet 39 are both connected to the separating base 332.

[0082] It is worth mentioning that the end cap body 321 is connected to the end of the separation top plate 331 facing away from the separation base 332. Specifically, the end cap body 321 can be detachably connected to the separation top plate 331 through a snap-fit ​​structure, a fastening structure or screws. When the end cap body 321 is connected to the separation top plate 331, the end face of the end cap body 321 facing the separation base 332 is attached to the openings of the first separation member 34 and the second separation member 35.

[0083] In addition, the end cap body 321 of this application can also be fixed to the separation top plate 331 with the assistance of other structures. For example, a separation fixing member 31 can be provided at the end of the end cap body 321 facing away from the separation base 332. The separation fixing member 31 can overlap the end cap body 321. A positioning member can be protruded on the separation fixing member 31. A positioning hole can be opened at the position of the positioning member on the end cap body 321. The positioning member can be inserted into the positioning hole. The positioning member can be fixedly connected to the separation top plate 331 by screws to fix the separation fixing member 31 to the separation top plate 331. At this time, the end cap body 321 is sandwiched in the middle by the separation fixing plate and the separation top plate 331. The end cap body 321 is tightened and fixed to the separation top plate 331 by the separation fixing plate.

[0084] It is worth mentioning that when the separation fixing member 31 is provided, the separation fixing member 31 is provided with through holes 531 at the positions corresponding to the first air outlet 3231 and the second air outlet 3232.

[0085] See Figure 8As shown, in some embodiments, the separation base 332 and separation top plate 331 of the separation bracket 33 can be movably connected to the dust collection structure 10. A first separation member 34 and a second separation member 35 are provided between the separation top plate 331 and the separation base 332. Adjacent first separation members 34 are spaced apart, and adjacent second separation members 35 are spaced apart. This allows the gap between the first separation members and the gap between the second separation members 35 to form a flow channel 334. The flow channel 334 is connected to the first air inlet 341 and the second air inlet 351, and the flow channel 334 is also connected to the dust collection structure 10. Air in the dust collection structure 10 can enter the flow channel 334, and the air in the flow channel 334 can enter the first receiving cavity 342 through the first air inlet 341 and enter the second receiving cavity 352 through the second air inlet 351.

[0086] See Figure 2 , Figure 13 and Figure 14 As shown, in some feasible implementations, the dust collection structure 10 includes a dust collection shell 11 and a dust collection box 12. The dust collection shell 11 is provided with a first dust collection chamber 111, and the dust collection box 12 is located in the first dust collection chamber 111. The outer wall of the dust collection box 12 is provided with a filter element 121. The filter element 121 and the inner wall of the dust collection shell 11 surround a separation space 13. The separation space 13 is connected to the flow channel 334. The filter element 121 is located between the separation space 13 and the flow channel 334. That is, the filter space separates the separation space 13 and the flow channel 334. The air in the separation space 13 can pass through the filter element 121 into the flow channel 334. At this time, the filter element 121 can filter the air in the separation space 13 and filter out some dust.

[0087] Combined Figure 15In some implementations, the dust collection structure 10 further includes a connecting shell 14 to which the dust collection shell 11 can be connected. The connecting shell 14 includes a first connecting portion 141, a second connecting portion 142, and an intermediate connecting portion 143. The first connecting portion 141 and the second connecting portion 142 are connected through the intermediate connecting portion 143. The end of the first connecting portion 141 away from the second connecting portion 142 can be used to connect to the suction base 21. One end of the dust collection shell 11 is open, and this opening communicates with the first dust collection chamber 111. The second connecting portion 142 and part of the intermediate connecting portion 143 of the connecting shell 14 can be inserted into the first dust collection chamber 111 through the opening of the dust collection shell 11. The open end of the dust collection shell 11 can be connected to the corresponding position of the intermediate connecting portion 143. The two can be connected by a snap-fit ​​structure, a fastening structure, or screws, so that the dust collection shell 11 and the intermediate connecting portion 143 are detachably connected. The inner wall shape and dimensions of the opening end of the dust collection shell 11 are consistent with the corresponding shape and dimensions of the intermediate connecting part 143, so that the inner wall of the opening end of the dust collection shell 11 can fit against the outer wall of the corresponding position of the intermediate connecting part 143, ensuring the sealing performance between the connection position of the dust collection shell 11 and the intermediate connecting part 143. Alternatively, a sealing ring can be provided between the opening end of the dust collection shell 11 and the fitting position of the intermediate connecting part 143 to increase the sealing performance of the connection between the two.

[0088] The first connecting portion 141, the second connecting portion 142, and the intermediate connecting portion 143 of this application are all provided with receiving spaces. The separation structure 30 and the shielding frame 50 can both be located within the receiving spaces. The shielding frame 50 is located within the first connecting portion 141, and the frame 51 of the shielding frame 50 is arranged in a ring. The outer surface of the frame 51 can fit against the inner wall of the first connecting portion 141. The separation structure 30 is located on the side of the frame 51 facing away from the suction structure 20, so that the separation structure 30 is sealed into the connecting shell 14 by the frame 51. The driving member 42 can drive the separation structure 30 to rotate within the space between the frame 51 and the first connecting portion 141 through the driving shaft 41.

[0089] In some implementations, the dust collection box 12 is connected to the separation structure 30 and can rotate with the separation structure 30. Specifically, the separation bracket 33 also includes a separation enclosure 333, which is connected to the separation base 332 and extends in a direction away from the separation top plate 331. The separation enclosure 333 is arranged around the drive shaft 41. The outer wall of the end of the separation enclosure 333 away from the separation base 332 can be attached to the inner wall of the end of the second connecting part 142 away from the first connecting part 141. When the drive member 42 drives the separation structure 30 to rotate as a whole, the outer wall of the separation enclosure 333 rotates along the inner wall of the second connecting part 142. To ensure the airtightness between the separation enclosure 333 and the second connecting part 142, an edge (not shown in the figure) can also be provided at the end of the second connecting part 142 away from the first connecting part 141. The edge can be made of flexible material and is tightly attached to the outer wall of the separation enclosure 333, which helps to increase the airtightness.

[0090] The dust collection box 12 includes a dust collection cylinder 122, which includes a cylinder body 1221, a connecting edge 1222, and an extending edge 1223. A second dust collection chamber 124 is provided inside the cylinder body 1221. One end of the cylinder body 1221 is open and connected to the separating base 332. Specifically, an annular protrusion can be provided on the separating base 332, and a connecting groove can be provided around the end face of the annular protrusion facing the cylinder body 1221. The open end of the cylinder body 1221 can be inserted into the connecting groove by a tight fit. This can both connect the cylinder body 1221 and the separating base 332 and ensure the airtightness of the second dust collection chamber 124, so that the second dust collection chamber 124 is connected to the dust outlet 39.

[0091] A connecting edge 1222 is connected to one end of the cylinder 1221 facing away from the opening. The connecting edge 1222 is circumferentially arranged on the outer wall of the cylinder 1221, and an angle is formed between the connecting edge 1222 and the outer wall of the cylinder 1221. An extension edge 1223 is connected to the end of the connecting edge 1222 away from the cylinder 1221. The filter element 121 has an annular structure. One end of the filter element 121 is connected to the end of the connecting edge 1222 away from the cylinder 1221, and the other end of the filter element 121 is connected to the end of the separation plate 333 away from the separation base 332. The outer wall of the filter element 121 and the inner wall of the separation plate 333 are in contact.

[0092] This allows the dust collection box 12 to be connected to the separation structure 30, so that the dust collection box 12 can rotate together with the separation structure 30.

[0093] It is understood that there is a gap between the filter element 121 and the cylinder 1221, which forms a transition channel 123. Air that has had some dust separated in the separation space 13 can penetrate from the filter element 121 into the transition channel 123. A space is also formed between the separation baffle 333 and the outer wall of the cylinder 1221. This space is connected to both the flow channel 334 and the transition channel 123, so that air in the flow channel 334 can flow into the flow channel 334 through the space between the separation baffle 333 and the cylinder 1221.

[0094] It should be noted that in some implementations, the air inlet 112 is located at the end of the dust collection shell 11 near its opening. The air sucked in by the dust collection assembly 202 can enter the first dust collection chamber 111 through the air inlet 112. In the first dust collection chamber 111, the dust is first separated by centrifugation and then enters the transition channel 123 through the filter element 121. The air filtered by the filter element 121 can then enter the flow channel 334 through the gap between the separation plate 333 and the cylinder 1221, and then flow into the first separator 34 and the second separator 35 through the first air inlet 341 and the second air inlet 351, respectively.

[0095] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
