Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of intelligent electrical appliances, in particular to a dust collection assembly and a robot vacuum cleaner. BACKGROUND

[0002] With the rapid development of electrical appliances, robot vacuum cleaners are increasingly selected by users. In a robot vacuum cleaner, a dust box and a fan are usually arranged, and the suction power of the fan is used to suck dust into the dust box to complete the dust collection function. Currently, the fan and the dust box of a traditional robot vacuum cleaner are usually arranged in front of or behind each other or to the left or right of each other. However, this arrangement of the fan is prone to cause a large gap between the dust box and the fan, and the gap space is difficult to be utilized, thereby causing the overall space utilization of the robot vacuum cleaner to decrease, which is not conducive to the lightweight development of the robot vacuum cleaner. SUMMARY

[0003] Therefore, it is necessary to provide a dust collection assembly and a robot vacuum cleaner to improve the overall space utilization of the robot vacuum cleaner and facilitate the lightweight development of the robot vacuum cleaner.

[0004] A dust collection assembly includes a dust box including an air outlet, the air outlet is inclined relative to a vertical direction, and the air outlet includes a first end and a second end higher than the first end along the vertical direction, and the second end is inclined relative to the first end away from one side of the inside of the dust box; a fan and a duct component, the fan is communicated with the air outlet through the duct component, and the projection of the duct component and the fan in a horizontal direction respectively at least partially overlaps the projection of the air outlet in the horizontal direction.

[0005] The dust collection assembly described above, the air outlet on one side of the dust box is arranged to be inclined relative to the vertical direction, and the second end of the air outlet protrudes more toward the outside of the dust box relative to the first end of the air outlet, so that the side surface of the air outlet is inclined downward. In this way, when the fan is matched with the air outlet through the duct component, the fan and the duct component are also arranged to be inclined downward. Since the projection of the fan and the duct component in the horizontal direction at least partially overlaps the projection of the air outlet in the horizontal direction, the fan and the duct component can be distributed as close to the dust box as possible when installed, thereby shortening the gap between the fan and the dust box, effectively improving the overall space utilization of the robot vacuum cleaner, and facilitating the lightweight development of the robot vacuum cleaner.

[0006] In some embodiments, the distance between the projection of the first end in the horizontal direction and the projection of the second end in the horizontal direction is denoted as D, where 6mm≤D≤10mm.

[0007] In some embodiments, the angle between the air outlet and the vertical direction is denoted as θ, where 20°≤θ≤30°.

[0008] In some embodiments, the length of the air duct component between the air outlet and the air fan is denoted as L, wherein 12mm≤L≤18mm.

[0009] In some embodiments, the dust box further comprises an abutting wall, which is located on the side of the second end away from the first end.

[0010] In some embodiments, the height of the abutting wall along the vertical direction is denoted as h1, and the height of the inclined installation wall along the vertical direction where the air outlet is located is denoted as h2, wherein 2.8≤h2 / h1≤3.2.

[0011] In some embodiments, the air duct component comprises a first shell and a second shell connected with the first shell, the second shell and the first shell form an air flow channel, the first shell is arranged on the air outlet, and the air fan is arranged in the second shell and communicates with the air outlet through the air flow channel.

[0012] In some embodiments, the dust collection assembly further comprises a sealing ring, which is annularly arranged on the outer periphery of the air outlet and located between the air outlet and the first shell.

[0013] In some embodiments, the air fan has an air inlet end, the air duct component has an air flow channel therein, the two ends of the air flow channel respectively communicate with the air outlet and the air inlet end, and the airflow flow direction in the air flow channel is perpendicular to the side surface of the air outlet towards the air duct component and the side surface of the air inlet end towards the air duct component, respectively.

[0014] In some embodiments, the dust collection assembly further comprises a detection assembly for obtaining the information of taking and placing the dust box in the robotic cleaner.

[0015] A robotic cleaner, comprising: a machine body having a mounting slot; the robotic cleaner as claimed in any one of the above, wherein the dust collection assembly is accommodated in the mounting slot.

[0016] The robotic cleaner described above adopts the dust collection assembly described above, wherein the air outlet on one side of the dust box is arranged to be inclined relative to the vertical direction, and the second end of the air outlet protrudes more towards the outside of the dust box relative to the first end of the air outlet, so that the side surface of the air outlet is inclined downward. In this way, when the air fan is matched with the air duct component at the air outlet, the air fan and the air duct component are also arranged to be inclined downward as a whole. Since the projections of the air fan and the air duct component in the horizontal direction at least partially overlap the projection of the air outlet in the horizontal direction, the air fan and the air duct component can be distributed as close to the dust box as possible during installation, thereby shortening the gap between the air fan and the dust box and effectively improving the space utilization of the robotic cleaner as a whole, which is conducive to the development of the lightweight and thin robotic cleaner.

[0031] The dust collection function of the robot vacuum cleaner is usually realized by the dust box 10 and the fan 30. In traditional robot vacuum cleaners, the fan 30 and the dust box 10 are usually arranged horizontally in front of and behind each other or to the left and right of each other. This arrangement results in a large gap between the fan 30 and the dust box 10. With the development of robot vacuum cleaners in the direction of lightness and thinness, the internal structure of the robot vacuum cleaner is becoming more and more compact. Obviously, this structure design cannot meet the development of robot vacuum cleaners in the direction of lightness and thinness, resulting in a decrease in the space utilization rate of the robot vacuum cleaner as a whole.

[0032] Therefore, in view of the low space utilization rate of the traditional robot vacuum cleaner, the present application provides a dust collection assembly 100, which comprises a dust box 10, an air duct component 20, and a fan 30. Figure 1 According to the dust collection assembly 100, the fan 30 and the air duct component 20 are arranged in a slanting downward manner, and the projections of the fan 30 and the air duct component 20 on the horizontal direction Y at least partially overlap the projection of the air outlet 113 on the horizontal direction Y. Therefore, the fan 30 and the air duct component 20 can be distributed as close to the dust box 10 as possible during installation, thereby shortening the gap between the fan 30 and the dust box 10 and effectively improving the space utilization rate of the robot vacuum cleaner as a whole, which is conducive to the development of the robot vacuum cleaner in the direction of lightness and thinness. Figure 2 The dust collection assembly 100 comprises a dust box 10, an air duct component 20, and a fan 30. The dust box 10 comprises an air outlet 113, which is inclined relative to the vertical direction X and comprises a first end 111 and a second end 112 higher than the first end 111 along the vertical direction X. The second end 112 is inclined relative to the first end 111 and protrudes more toward the outside of the dust box 10. The fan 30 is in communication with the air outlet 113 through the air duct component 20, and the projections of the fan 30 and the air duct component 20 on the horizontal direction Y at least partially overlap the projection of the air outlet 113 on the horizontal direction Y.

[0033] The dust collection assembly 100 described above is arranged in a slanting manner relative to the vertical direction X at the air outlet 113 on one side of the dust box 10, and the second end 112 of the air outlet 113 protrudes more toward the outside of the dust box 10 relative to the first end 111 of the air outlet 113, so that the outer side of the air outlet 113 is inclined downward. When the fan 30 is fitted at the air outlet 113 through the air duct component 20, the fan 30 and the air duct component 20 are also arranged in a slanting downward manner as a whole. Since the projections of the fan 30 and the air duct component 20 on the horizontal direction Y at least partially overlap the projection of the air outlet 113 on the horizontal direction Y, the fan 30 and the air duct component 20 can be distributed as close to the dust box 10 as possible during installation, thereby shortening the gap between the fan 30 and the dust box 10 and effectively improving the space utilization rate of the robot vacuum cleaner as a whole, which is conducive to the development of the robot vacuum cleaner in the direction of lightness and thinness.

[0034] In addition, the air outlet 113 is inclined relative to the vertical direction X in this embodiment, so that when the dust box 10 is installed in the robot cleaner, the air outlet 113 can exert a pressure on the air duct component 20, the pressure being perpendicular to the fitting surface between the air duct component 20 and the air outlet 113, thereby serving to compress the air duct component 20. This makes the connection between the dust box 10 and the air duct component 20 more compact, improves the sealing between the dust box 10 and the air duct component 20, and is conducive to improving the dust collection effect of the robot cleaner.

[0035] It should be noted that when the dust box 10 is installed in the robot cleaner or the dust box 10 is in a normal placement state, the air outlet 113 on the dust box 10 is arranged to be inclined relative to the vertical direction X, and the second end 112 of the air outlet 113 is more outwardly inclined and protrudes relative to the first end 111, so that the outer side surface of the air outlet 113 is arranged to be inclined downward. At this time, the air duct component 20 fitted on the air outlet 113 and the air blower 30 are closer to the dust box 10, reducing the gap between the air blower 30 and the dust box 10. The normal placement state of the dust box 10 can be understood as the state of the dust box 10 when the bottom of the dust box 10 is placed on a horizontal surface. Meanwhile, it can be known that the mounting wall 11 where the air outlet 113 is located is also arranged to be inclined relative to the vertical direction X,

[0036] To facilitate the taking and placing of the dust box 10 from the robot cleaner, the fitting mode between the air duct component 20 and the air outlet 113 can be a press-fit mode, for example, one end of the air duct component 20 is press-fitted on the outer periphery of the air outlet 113 and communicates with the air outlet 113. Of course, to avoid pressure relief between the air outlet 113 and the air duct component 20, a sealing structure can also be provided between the air duct component 20 and the outer periphery of the air outlet 113.

[0037] When the air blower 30 and the air duct component 20 are fitted on the air outlet 113, the projections of the air blower 30 and the air duct component 20 on the horizontal direction Y at least partially overlap the projection of the air outlet 113 on the horizontal direction Y, indicating that when the air blower 30 and the air duct component 20 are inclined and fitted on the air outlet 113, at least a part of the air blower 30 and the air duct component 20 will be inclined and extend below the air outlet 113, so that the space below the air outlet 113 is occupied by the air blower 30 and the air duct component 20, reducing the waste of space between the air blower 30 and the dust box 10.

[0038] It should be noted that the projection of the air duct component 20 in the horizontal direction Y can partially cover the projection of the air outlet 113 in the horizontal direction Y, or can completely cover the projection of the air outlet 113 in the horizontal direction Y. At this time, the overlapping part between the projection of the air duct component 20 in the horizontal direction Y and the projection of the air outlet 113 in the horizontal direction Y is the projection of the air outlet 113 in the horizontal direction Y. Similarly, the projection of the fan 30 in the horizontal direction Y can partially cover the projection of the air outlet 113 in the horizontal direction Y, or can completely cover the projection of the air outlet 113 in the horizontal direction Y.

[0039] In addition, the connection mode between the fan 30 and the air duct component 20 can have various modes, such as but not limited to bolt connection, clamping, pin connection, welding, etc.

[0040] Further, please refer to Figure 3 The distance between the projection of the first end 111 in the horizontal direction Y and the projection of the second end 112 in the horizontal direction Y is denoted as D, wherein 6mm≤D≤10mm. It can be seen that the distance between the projection of the first end 111 and the projection of the second end 112 refers to the size of the projection of the air outlet 113 in the thickness direction in the horizontal direction. The value of the distance D should not be too large or too small. If it is too small, the overlapping part of the projection between the fan 30 and the air outlet 113 is reduced, the gap between the fan 30 and the dust box 10 is increased, and the space utilization is reduced. If it is too large, the overall size of the dust box 10 in the horizontal direction is increased, and the volume of the dust box 10 is increased.

[0041] Therefore, the distance D is controlled between 6mm and 10mm in the embodiment, such as but not limited to 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc. In this way, the distance D is reasonably set, the overall size of the dust box 10 is reasonably controlled, the overlapping parts of the projection between the air outlet 113 and the fan 30 and the air duct component 20 are increased respectively, the distribution of the fan 30 and the air duct component 20 can fully utilize the space between the dust box 10 and the fan 30, the space utilization is improved, and it is beneficial to the light and thin development of the sweeping robot.

[0042] In some embodiments, the angle between the air outlet 113 and the vertical direction X is denoted as θ, wherein 20°≤θ≤30°. It can be seen that the larger the angle between the air outlet 113 and the vertical direction X, the more the air outlet 113 tends to be horizontal. If the angle between the air outlet 113 and the vertical direction X is too large, the installation of the fan 30 and the air duct component 20 tends to be more horizontal, and at this time the fan 30 and the air duct component 20 are more likely to interfere with the structure of the dust box 10 in the horizontal direction. If interference is to be avoided, the length of the air outlet 113 needs to be lengthened, which will also increase the overall size of the dust box 10.

[0043] To this end, the included angle between the air outlet 113 and the vertical direction X is controlled to be 20°-30°, such as: the included angle can be, but is not limited to, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, etc. In this way, while meeting the effective inclined installation of the air duct component 20 and the fan 30, the overall size of the dust box 10 in the horizontal direction is reasonably controlled.

[0044] It should be noted that when the included angle between the air outlet 113 and the vertical direction X is controlled to be 20°-30°, the spacing between the projection of the second end 112 of the air outlet 113 on the horizontal direction Y and the projection of the first end 111 of the air outlet 113 on the horizontal direction Y can be controlled to be 6mm-10mm. In this way, the space utilization of the robot and the overall size design of the dust box 10 are more effectively balanced.

[0045] In some embodiments, please refer to Figure 3 , the length of the air duct component 20 between the air outlet 113 and the fan 30 is denoted as L, wherein 12mm≤L≤18mm. Wherein, the length of the air duct component 20 between the air outlet 113 and the fan 30 can be understood as the length of the air duct component 20 along the airflow direction. If the length of the air duct component 20 is designed too long, it will increase the gap between the fan 30 and the dust box 10, resulting in reduced space utilization; if the length of the air duct component 20 is designed too short, it will make the installation of the fan 30 difficult, and as the air outlet 113 is inclined, it will also cause the installation of the fan 30 to easily interfere with the dust box 10. Therefore, the length of the air duct component 20 is controlled to be 12mm-18mm in this embodiment, such as: can be, but is not limited to, 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, etc.

[0046] In this way, the length L of the air duct component 20 is controlled to be 12mm-18mm, so that the fan 30 can be effectively installed on the air outlet 113, while also reducing the waste of space between the fan 30 and the dust box 10, and improving the space utilization of the robot.

[0047] In some embodiments, please refer to Figure 2 , Figure 6 and Figure 7 , the dust box 10 further comprises an abutting wall 12 located on the side of the second end 112 away from the first end 111. As can be seen, when the dust box 10 is installed in the robot, the abutting wall 12 will abut against the upper shell 210 of the robot, ensuring that the fixing of the dust box 10 in the robot is more stable.

[0048] The abutting wall 12 refers to a structure on the dust box 10 at the side of the second end 112 of the air outlet 113, which can be connected with the second end 112. In order to improve the combination between the abutting wall 12 and the upper shell 210 of the robot, the abutting wall 12 can be designed as a structure matching the upper shell 210 of the robot, for example, the abutting wall 12 can be designed as a structure parallel to the vertical direction X, i.e., a vertical surface.

[0049] Further, referring to Figure 3 , the height of the abutting wall 12 along the vertical direction X is h1, and the height of the inclined mounting wall 11 where the air outlet 113 is located along the vertical direction X is h2, wherein 2.8≤h2 / h1≤3.2. The ratio of the height h2 of the mounting wall 11 and the height h1 of the abutting wall 12 in the embodiment can affect the installation of the fan 30 and the installation of the dust box 10 in the robot. If the ratio of the height of the mounting wall 11 and the height of the abutting wall 12 is too small, the fan 30 cannot be stably fixed on the mounting wall 11; if the ratio of the height of the mounting wall 11 and the height of the abutting wall 12 is too large, the area of the abutting wall 12 is small, so that the abutting wall 12 cannot stably abut with the upper shell 210 of the robot.

[0050] Therefore, in the embodiment, the ratio h2 / h1 is controlled between 2.8 and 3.2, for example, but not limited to 2.8, 2.85, 2.9, 2.95, 3, 3.05, 3.1, 3.15, 3.2, etc. By designing the ratio of the height of the mounting wall 11 and the height of the abutting wall 12 between 2.8 and 3.2, not only the stable installation of the fan 30 on the air outlet 113 is satisfied, but also the stable abutment of the dust box 10 and the upper shell 210 of the robot is ensured, and the stability of the installation of the dust box 10 is improved.

[0051] In some embodiments, referring to Figure 4 , the air duct component 20 includes a first shell 21 and a second shell 22 connected with the first shell 21, the second shell 22 and the first shell 21 form an air flow channel 23, the first shell 21 is arranged on the air outlet 113, the fan 30 is arranged on the second shell 22 and communicates with the air outlet 113 through the air flow channel 23. It can be seen that the air duct component 20 is designed as the first shell 21 and the second shell 22, which facilitates the stable installation of the air duct component 20 and the fan 30.

[0052] It should be noted that the first shell 21 and the second shell 22 define the air flow channel 23, so that when the fan 30 works, the fan 30 can draw air into the dust box 10 through the air flow channel 23, so that a negative pressure is formed in the dust box 10, and dust can be effectively sucked into the dust box 10. The first shell 21 and the second shell 22 can be connected in a non-detachable manner, such as welding, riveting, and one-piece molding, etc., wherein the one-piece molding can be, but is not limited to, injection molding, die casting, 3D printing, etc. At the same time, the first shell 21 and the second shell 22 can also be connected in a detachable manner, such as bolt connection, clamping, etc.

[0053] Specifically, please refer to Figure 4 , the first shell 21 is provided with a buckle protrusion 212, and the second shell 22 is provided with a clasp 221, and the buckle protrusion 212 is inserted into the clasp 221. At the same time, the number of the buckle protrusion 212 and the clasp 221 can be one or more. When the buckle protrusion 212 and the clasp 221 are both multiple, all the buckle protrusions 212 are arranged along the circumference of the first shell 21, and all the clasps 221 are arranged along the circumference of the second shell 22. Of course, in other embodiments, the first shell 21 can be provided with a clasp 221, and the second shell 22 can be provided with a buckle protrusion 212 matched with the clasp 221.

[0054] In addition, the fixing manner of the fan 30 on the second shell 22 also has many kinds, such as bolt connection, clamping, riveting, bonding, welding, etc.

[0055] Further, please refer to Figure 2 , Figure 4 and Figure 5 , the dust collecting assembly 100 further comprises a sealing ring 50, which is annularly arranged on the outer periphery of the air outlet 113 and located between the air outlet 113 and the first shell 21. In this way, the sealing ring 50 is arranged between the air outlet 113 and the first shell 21, so that the air duct component 20 is tightly matched at the air outlet 113, effectively improving the sealing between the dust box 10 and the air duct component 20, and being beneficial to improving the dust collecting effect of the sweeping robot.

[0056] It should be noted that since the dust box 10 needs to be taken out from the sweeping robot alone, the sealing ring 50 is either fixed on the air outlet 113 or fixed on the first shell 21. The arrangement manner of the sealing ring 50 on the air outlet 113 or the first shell 21 has many kinds, such as clamping, bonding, etc.

[0057] Specifically, please refer to Figure 4The first shell 21 is provided with a fixing groove 211, and the sealing ring 50 is clamped into the fixing groove 211. In this way, the fixing groove 211 is arranged on the first shell 21, so that the sealing ring 50 is stably mounted on the first shell 21, and the sealing performance between the air duct component 20 and the air outlet 113 is improved.

[0058] In some embodiments, referring to Figure 3 The fan 30 has an air inlet end 31, and the air duct component 20 has an air flow channel 23, two ends of the air flow channel 23 are respectively communicated with the air outlet 113 and the air inlet end 31, and the airflow flow direction in the air flow channel 23 is perpendicular to the side of the air outlet 113 towards the air duct component 20 and the side of the air inlet end 31 towards the air duct component 20. Therefore, the air outlet 113, the air duct component 20 and the fan are distributed in a similar I-shaped manner, and the air flow channel 23 formed in this way is short and smooth between the air outlet 113 and the air inlet end 31, which reduces the loss of airflow, and thus is conducive to improving the dust collection performance of the robot.

[0059] It should be noted that the airflow flow direction in the air flow channel 23 refers to the flow direction of the airflow in the air flow channel 23 under the action of suction. Of course, it can also be understood as the extension direction of the air flow channel 23 or the direction of the central axis thereof.

[0060] In some embodiments, referring to Figure 2 The dust collection assembly 100 further comprises a detection assembly 40, which is used to obtain the taking and placing information of the dust box 10 in the robot. In this way, whether the dust box 10 is taken out of the robot is determined by the detection assembly 40.

[0061] It should be noted that when the dust box 10 is taken out of the robot, the detection assembly 40 cannot detect the dust box 10, and sends a taking-out signal to the robot. At this time, the robot can control the fan 30 to stop starting, so as to avoid that the fan 30 is started by mistake when the dust box 10 is not installed in the robot, which causes equipment failure. The detection method of the detection assembly 40 is various, such as: judging whether the dust box 10 exists in the robot by contact sensing, for example, the detection assembly 40 can be but is not limited to a sensing wire; or judging whether the dust box 10 exists in the robot by magnetic induction or photoelectric induction, for example, the detection assembly 40 can be but is not limited to a Hall sensor assembly or an infrared light sensor assembly.

[0062] Specifically, the detection assembly 40 comprises a Hall sensor and a magnet. The Hall sensor is arranged on the air duct component 20, and the magnet is arranged on the dust box 10. When the dust box 10 is taken out of the robot, the Hall sensor does not sense the magnet, and feeds back a corresponding taking-out signal to the robot. When the dust box 10 is placed back in the robot, the Hall sensor senses the magnet, and feeds back a corresponding placing signal to the robot. In this way, the user can be effectively reminded to avoid misuse.

[0063] In addition, to avoid dust entering the fan 30 along with the airflow, the dust collection assembly 100 can further comprise a filter screen 60. The filter screen 60 can be arranged in the dust box 10 to filter dust in the airflow, avoid dust entering the fan 30, damage the fan 30, and reduce the service life of the fan 30.

[0064] In some embodiments, referring to Figure 6 With Figure 7 The application provides a robot, which comprises a robot body 200 and the robot of any one of the above. The robot body 200 has a mounting groove 230, and the dust collection assembly 100 is accommodated in the mounting groove 230.

[0065] The robot described above adopts the dust collection assembly 100 described above. The air outlet 113 on one side of the dust box 10 is arranged obliquely relative to the vertical direction X, and the second end 112 of the air outlet 113 protrudes more outward than the first end 111. Therefore, the air outlet 113 is inclined downward. When the fan 30 is fitted in the air outlet 113 through the air duct component 20, the fan 30 and the air duct component 20 are also arranged obliquely downward. Since the projections of the fan 30 and the air duct component 20 on the horizontal direction Y at least partially overlap the projection of the air outlet 113 on the horizontal direction Y, the fan 30 and the air duct component 20 can be distributed as close to the dust box 10 as possible when installed, thereby shortening the gap between the fan 30 and the dust box 10, effectively improving the space utilization of the robot, and facilitating the development of the robot in the direction of lightness and thinness.

[0066] It should be noted that when the dust box 10 is accommodated in the mounting groove 230, the fan 30 and the air duct component 20 are fixed in the robot body 200. In addition, to further improve the stability of the dust collection assembly 100 in the robot, the air duct component 20 can be fixed in the robot body 200 by means of bolt connection, clamping, riveting, etc. In addition, when the dust box 10 is accommodated in the mounting groove 230, the fan 30 and the air duct component 20 can also be accommodated in the mounting groove 230, so as to ensure that the overall structure of the robot is more compact.

[0067] Further, referring to Figure 7The machine body 200 comprises a base 220 and an upper shell 210 arranged on the base 220, the base 220 is provided with a mounting groove 230, and the dust box 10 is accommodated in the mounting groove 230. In this way, the machine body 200 is designed as the upper shell 210 and the base 220, so as to facilitate stable fixation of the dust collection assembly 100 in the robot cleaner. The connection mode between the upper shell 210 and the base 220 can be various, such as but not limited to bolt connection, clamping, riveting, welding, bonding and the like.

[0068] Further, please refer to Figure 1 and Figure 7 In order to further provide the stability of the fixation of the dust box 10 in the mounting groove 230, an elastic buckle 13 can be arranged on the dust box 10, and when the dust box 10 is loaded into the mounting groove 230, the elastic buckle 13 is clamped on the groove wall of the mounting groove 230. At the same time, since the elastic buckle 13 is arranged on the dust box 10, when the dust box 10 is taken out, the elastic buckle 13 can be pressed to release the connection of the dust box 10 in the mounting groove 230, so that the dust box 10 is more convenient to take out.

[0069] In addition, when the dust box 10 is fixed in the mounting groove 230 by the elastic buckle 13, the dust box 10 will apply a downward oblique pressure to the air duct component 20, so that the dust box 10 is tightly combined with the air duct component 20, and the sealing property between the dust box 10 and the air duct component 20 is improved.

[0070] In some embodiments, please refer to Figure 2 and Figure 7 The dust box 10 further comprises an abutting wall 12, the air outlet 113 comprises a first end 111 and a second end 112 which are spaced apart along the vertical direction X, and the abutting wall 12 is located on the side of the second end 112 away from the first end 111. When the dust box 10 is loaded into the mounting groove 230, the abutting wall 12 will abut against the groove wall of the mounting groove 230, so that the dust box 10 is more stably fixed in the machine body 200.

[0071] In some embodiments, please refer to Figure 4 and Figure 7 The air duct component 20 comprises a first shell 21 and a second shell 22 matched with the first shell 21, and a wind flow channel 23 is defined between the first shell 21 and the second shell 22, and the fan 30 is in communication with the air outlet 113 through the wind flow channel 23. At the same time, when the dust collection assembly 100 is loaded into the mounting groove 230, the air duct component 20 can be fixed on the base 220. In some embodiments, the second shell 22 is provided with a threaded hole 222, and when the dust collection assembly 100 is loaded into the mounting groove 230, the second shell 22 can be fixed on the base 220 by penetrating a bolt or a screw into the threaded hole 222.

[0072] Any combination of the technical features in the above-described embodiments can be made, and for the sake of brevity, not all possible combinations are described, however, it is to be understood that the application embraces all such possible combinations.

[0073] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the patent protection scope of the present application should be subject to the appended claims.
