Many specific details are set forth in the following description to fully understand the present application. However, the present application can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present application. Therefore, the present application is not limited by the specific embodiments disclosed below.

[0061] In the description of the present application, it should be understood that if terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or positional relationship indicated by these terms is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0062] In addition, if terms such as "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0063] In this application, unless otherwise clearly specified and defined, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense.

[0065] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation manner.

[0066] Refer to Figures 1 to 3 , a cyclone separator provided in an embodiment of the present application is used to be installed in the dust cup 100 of the dust collection device to separate the dust and air flow entering the dust cup 100, so that the dust is separated and collected in the dust cup 100, and the clean air flow is filtered by the Hepa 800 to further improve the cleanliness and then flows out of the dust cup 100 and enters the motor.

[0067] Refer to Figures 2 to 4 , a cyclone separator provided in an embodiment of the present application includes a filter net 200, an upper cyclone cone mechanism 300 and a lower cyclone cone mechanism 400. An outer wall of the filter net 200 can form a primary dust collection chamber 110 between the inner wall of the dust cup 100, and a mixture inlet 711 for air flow and dust to enter is provided at the central position of the cyclone separator, and the mixture inlet 711 communicates with the primary dust collection chamber 110. At the same time, refer to Figures 6 to 8, the upper cyclone cone mechanism 300 includes a plurality of upper cyclone cones 310 disposed around the outer periphery of the mixture inlet 711, and the lower cyclone cone mechanism 400 includes a plurality of lower cyclone cones 410. The upper cyclone cones 310 are located on the side of the lower cyclone cones 410 away from the bottom wall of the dust cup 100.

[0068] The above-mentioned cyclone separator is installed in the dust cup 100 of the dust collection device. In the cyclone separator, a primary dust collection chamber 110 can be formed between the outer wall of the filter net 200 and the inner wall of the dust cup 100. The mixture inlet 711 for air flow and dust to enter the cyclone separator is communicated with the primary dust collection chamber 110. Therefore, the air flow and dust mixture entering the cyclone separator from the central position will first reach the outside of the filter net, and pass through the filter net 200 for filtration, so that large-sized dust is first separated and collected in the primary dust collection chamber 110 outside the filter net 200 to complete the primary separation. The dust with slightly smaller size passes through the filter net 200 with the air flow and reaches the inside thereof. A plurality of upper cyclone cones 310 and a plurality of lower cyclone cones 410 are both located inside the filter net 200, and the upper cyclone cones 310 are located on the side of the lower cyclone cones 410 away from the bottom wall of the dust cup 100, that is, in the use state, the upper cyclone cones 310 are located above the lower cyclone cones 410. The larger particle dust reaching the inside of the filter net 200 will be lower in position under the action of gravity. Since the upper cyclone cones 310 are located above the lower cyclone cones 410, the larger particle dust with a lower position will mainly flow into the lower cyclone cones 410 for cyclone separation, and the smaller particle dust with a higher position mainly flows into the upper cyclone cones 310 for cyclone separation. In this way, on the basis of the primary separation, the upper and lower cyclone cones can respectively perform secondary separation on the dust at different positions, making the separation more comprehensive and thorough, and achieving a better separation effect.

[0069] Refer to Figures 6 to 8 , the radial dimension of the upper cyclone cone 310 is smaller than that of the lower cyclone cone 410.

[0070] Part of the dust and air flow reaching the inside of the filter net 200 will enter the upper cyclone cones 310, and part will enter the lower cyclone cones 410 to complete the secondary separation. According to the common general knowledge in the art, the smaller the radial dimension of the cyclone cone, the smaller the dust particles that can be separated. Then, setting the radial dimension of the upper cyclone cone 310 to be smaller than that of the lower cyclone cone 410 can better match the dust of different sizes entering the upper cyclone cones 310 and the lower cyclone cones 410, so as to more specifically perform secondary separation on the dust of different sizes on the basis of the primary separation, and achieve a better separation effect.

[0071] Refer to Figure 3 、 Figure 4 、 Figure 8 And Figure 9, in some embodiments, the cyclone separator includes a wind guiding mechanism 500. The wind guiding mechanism 500 includes a plurality of wind guiding pipes 510. One end of each wind guiding pipe 510 is inserted into a corresponding lower cyclone cone 410, and the other end passes through the upper cyclone cone mechanism 300. The wind guiding pipes 510 are used to discharge the clean air flow separated by the lower cyclone cone 410.

[0072] Specifically, the wind guiding mechanism 500 is located inside the filter net 200. The bottom end of each wind guiding pipe 510 is inserted downward into a corresponding lower cyclone cone 410, and the top end passes upward through the upper cyclone cone mechanism 300. There is a lower cyclone chamber 411 inside the lower cyclone cone 410. The lower cyclone chamber 411 has a lower air inlet 412. The dust and air flow that pass through the filter net 200 and reach the lower part inside it can flow into the lower cyclone chamber 411 tangentially from the lower air inlet 412. Since the bottom end of the wind guiding pipe 510 is inserted into the lower cyclone cone 410, the dust and air flow flowing into the lower cyclone chamber 411 will rotate around the wind guiding pipe 510, thus realizing cyclone separation. The separated clean air flow is discharged upward through the wind guiding pipe 510, and the dust is deposited downward. The HEPA 800 is located above the wind guiding pipe 510. The clean air flow discharged upward from the top end of the wind guiding pipe 510 will flow into the HEPA 800 for filtration. In the embodiment shown in the figure, there are 6 lower cyclone cones 410. Therefore, at the corresponding positions, a total of 6 wind guiding pipes 510 are provided that match them.

[0073] Refer to Figure 9 , in some embodiments, the plurality of wind guiding pipes 510 are connected together by an integrally formed manner. Specifically, the wind guiding mechanism 500 includes an intermediate plate 520, and the plurality of wind guiding pipes 510 are all connected to the intermediate plate 520.

[0074] Refer to Figure 4 、 Figure 8 and Figure 9 , in some embodiments, among the wind guiding mechanism 500 and the lower cyclone cone mechanism 400, one of them has a clamping groove 531, and the other has a clamping block 4131, and the clamping block 4131 is clamped in the clamping groove 531.

[0075] Specifically, the wind guiding mechanism 500 includes a flanging 530 that is folded downward from the outer edge of the intermediate plate 520. The flanging 530 has a clamping groove 531, and the lower cyclone cone mechanism 400 has a clamping block 4131. By clamping the clamping block 4131 into the clamping groove 531, the connection and fixation between the wind guiding mechanism 500 and the lower cyclone cone mechanism 400 can be realized.

[0076] Refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 and Figure 9, in some embodiments, the air duct 510 includes a lower air guiding portion 512 inserted into the lower cyclone cone 410 and an upper air guiding portion 511 passing through the upper cyclone cone mechanism 300. The upper air guiding portion 511 and the upper cyclone cone 310 are offset in position. The lower air guiding portion 512 and the upper air guiding portion 511 are in communication, and their central axes do not coincide.

[0077] Specifically, the lower air guiding portion 512 is connected to the bottom end of the upper air guiding portion 511, and the two are in internal communication for the air flow to pass through. The upper air guiding portion 511 extends upward from the middle plate 520. The upper cyclone cone mechanism 300 has a plurality of hollow holes 340, and the positions of the respective hollow holes 340 are offset from the position of the upper cyclone cone 310. Each of the hollow holes 340 is respectively used for the respective upper air guiding portions 511 to pass through upward. Referring also to Figure 10 , the lower air guiding portion 512 passes through the middle plate 520, that is, the bottom end portion of the lower air guiding portion 512 extends downward from the middle plate 520, and the top end portion extends upward from the middle plate 520. The top end portion of the lower air guiding portion 512 is in communication with the upper air guiding portion 511. Both the lower air guiding portion 512 and the upper air guiding portion 511 are columnar tubes, and their central axes do not coincide. Further, the central axis of the lower air guiding portion 512 is closer to the central region of the middle plate 520 than that of the upper air guiding portion 511, that is, the central axis of the lower air guiding portion 512 is located inside the central axis of the upper air guiding portion 511.

[0078] In the above embodiments, by setting the central axes of the lower air guiding portion 512 and the upper air guiding portion 511 not to coincide, the air duct 510 can just occupy the gap inside the filter net 200 outside the upper cyclone cone mechanism 300 and the lower cyclone cone mechanism 400, without increasing the inner space of the filter net 200 for setting the air duct 510, that is, without increasing the size of the filter net 200. Thus, it is beneficial to reduce the size of the cyclone separator. When it is placed in the dust cup 100, the space of the primary dust collection chamber 110 between the inner wall of the dust cup 100 and the cyclone separator will be larger, and more dust particles can be accommodated.

[0079] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 12 , in some embodiments, the cyclone separator includes an exhaust mechanism 600 for being disposed on the air inlet side of the Hepa 800 of the dust collection device. The exhaust mechanism 600 includes a plurality of upper exhaust pipes 610 and a plurality of lower exhaust pipes 620. Each upper exhaust pipe 610 is inserted into a corresponding upper cyclone cone 310 for exhausting the clean air flow separated by the upper cyclone cone 310, and each lower exhaust pipe 620 is inserted into a corresponding air duct 510.

[0080] Specifically, the exhaust mechanism 600 includes a base plate 630 and a surrounding plate 640. The surrounding plate 640 extends upward from the outer edge of the base plate 630, and the recessed area formed by the two can be used to install the HEPA 800. The top of the upper cyclone cone mechanism 300 is recessed downward. The exhaust mechanism 600 is placed in this recess and is located above the upper cyclone cone 310 and the air duct 510. Both the upper exhaust pipe 610 and the lower exhaust pipe 620 protrude downward from the base plate 630. The upper cyclone cone 310 has an upper cyclone chamber 311, and the upper cyclone chamber 311 has an upper air inlet 312. The dust and air flow that pass through the filter net 200 and reach the upper inner part thereof can flow into the upper cyclone chamber 311 along the tangential direction from the upper air inlet 312. The upper exhaust pipe 610 is inserted into the corresponding upper cyclone cone 310. Therefore, the dust and air flow flowing into the upper cyclone chamber 311 will rotate around the upper exhaust pipe 610, thereby realizing cyclone separation. The separated clean air flow is discharged upward through the upper exhaust pipe 610, and the dust is deposited downward. The lower exhaust pipe 620 is inserted into the corresponding air duct 510, so that the clean air flow separated in the corresponding lower cyclone cone 410 is discharged upward through the air duct 510 and the lower exhaust pipe 620 in sequence. Through holes are provided at the positions of the base plate 630 corresponding to the upper exhaust pipe 610 and the lower exhaust pipe 620, so that the air flow discharged from the tops of the upper exhaust pipe 610 and the lower exhaust pipe 620 can pass through the base plate 630 and enter the HEPA 800.

[0081] Refer to Figure 2 、 Figure 3 、 Figure 4 And Figure 11 , in some embodiments, the cyclone separator includes a cyclone hood 700. The cyclone hood 700 includes an inner cylinder 710 and an outer cylinder 720 spaced outside the inner cylinder 710. A secondary dust collection chamber 730 is formed between the inner cylinder 710 and the outer cylinder 720. One end of each lower cyclone cone 410 facing away from the corresponding air duct 510 is inserted into the secondary dust collection chamber 730 to discharge the separated dust into the secondary dust collection chamber 730.

[0082] Specifically, the inner cylinder 710 and the outer cylinder 720 are integrally connected, and a conical secondary dust collection chamber 730 that is larger at the top and smaller at the bottom is formed between them. The secondary dust collection chamber 730 and the aforementioned primary dust collection chamber 110 are respectively located inside and outside the outer cylinder 720. The bottom end of each lower cyclone cone 410 is inserted downward into the secondary dust collection chamber 730, and the dust separated by each lower cyclone cone 410 falls downward into the secondary dust collection chamber 730, thereby realizing dust collection.

[0083] Refer to Figure 3 、 Figure 8 And Figure 11 , in some embodiments, one end of the lower cyclone cone 410 facing away from the corresponding air duct 510 is inclined toward the side close to the central axis of the cyclone separator.

[0084] Specifically, one end of the lower cyclone cone 410 facing away from the corresponding air duct 510 is inclined towards the inner cylinder 710. That is, the bottom end of the lower cyclone cone 410 is inclined inwards, so that the outer cylinder 720 can also be inclined inwards as much as possible to increase the space of the primary dust collection chamber 110.

[0085] In some embodiments, the included angle between the central axis of the lower cyclone cone 410 and the central axis of the cyclone separator ranges from 5° to 9°. Preferably, the included angle is 7°.

[0086] Refer to Figure 3 、 Figure 8 And Figure 11 In some embodiments, multiple regions of the outer cylinder 720 protrude outwards to form protrusions 721. The inner region of each protrusion 721 is used to accommodate a lower cyclone cone 410, and their shapes and sizes are adapted to fit each other.

[0087] Specifically, the number, position of the protrusions 721 match those of the lower cyclone cones 410. After the protrusions 721 are formed, both the inner wall and the outer wall of the protrusions 721 protrude outwards, and the inner wall will be inclined, which can match the inclined outer surface shape of the lower cyclone cone 410, better accommodating the lower cyclone cone 410. Moreover, this inclined setting method is beneficial to reducing the length of the entire dust cup 100. In addition, the outer wall of the protrusion 721 is convex, which can reduce the rotational movement of large particle garbage and hair deposited in the primary dust collection chamber 110, making it stably stay at the bottom of the primary dust collection chamber 110. And a concave region will be formed between the outer walls of adjacent protrusions 721, which can facilitate the removal of hair wound around the outer wall of the protrusion 721 through the concave region.

[0088] Refer to Figure 6 、 Figures 8 to 10 In some embodiments, the lower cyclone cone mechanism 400 has a plurality of dust discharge holes 420 communicating with the secondary dust collection chamber 730. The dust discharge holes 420 are staggered with the lower cyclone cones 410. One end of each upper cyclone cone 310 close to the lower cyclone cone mechanism 400 is communicated with a corresponding dust discharge hole 420 to discharge the separated dust into the secondary dust collection chamber 730 through the dust discharge holes 420.

[0089] Specifically, the dust discharge holes 420 penetrate the lower cyclone cone mechanism 400 up and down, so as to communicate with the secondary dust collection chamber 730. A plurality of through holes 521 are provided on the middle plate 520 of the air guiding mechanism 500. The bottom end of each upper cyclone cone 310 is inserted into a corresponding through hole 521. Each through hole 521 corresponds to and communicates with a dust discharge hole 420 below it. That is, the bottom end of each upper cyclone cone 310 is communicated with the corresponding dust discharge hole 420 through the through hole 521. The dust separated by each upper cyclone cone 310 sequentially passes through the through hole 521 and the dust discharge hole 420 downwards and falls into the secondary dust collection chamber 730, thereby realizing dust collection.

[0090] Refer to Figure 3 and Figure 7 In some embodiments, one end of the upper cyclone cone 310 close to the lower cyclone cone mechanism 400 is inclined toward the side close to the central axis of the cyclone separator.

[0091] Specifically, one end of the upper cyclone cone 310 close to the lower cyclone cone mechanism 400 is inclined toward the side close to the inner cylinder 710. That is, the bottom end of the upper cyclone cone 310 is inclined inward, so that the bottom end of the upper cyclone cone 310 can be aligned with the dust discharge hole 420 at the gap between the lower cyclone cones 410, thereby making more effective use of space and making the structure more compact.

[0092] In some embodiments, the included angle between the central axis of the upper cyclone cone 310 and the central axis of the cyclone separator ranges from 3° to 6°. Preferably, the included angle is 4.5°.

[0093] Refer to Figure 3 and Figure 4 and Figure 6 and Figure 7 In some embodiments, a mixture inlet 711 is formed on the inner side of the inner cylinder 710. The upper cyclone cone mechanism 300 includes a central column 320 communicated with the inner cylinder 710 and a wind guiding channel 330 communicated with the central column 320. A plurality of upper cyclone cones 310 are all distributed outside the central column 320. The wind guiding channel 330 is spiral and extends from the center of the upper cyclone cone mechanism 300 toward the edge. The airflow and dust flowing in from the mixture inlet 711 can enter the primary dust collection chamber 110 through the central column 320 and the wind guiding channel 330 in sequence.

[0094] Specifically, the inner cylinder 710 is located at the central position of the whole cyclone separator. The airflow and dust mixture flows upward into the cyclone separator from the bottom end of the inner cylinder 710 through the mixture inlet 711. At the same time, refer to Figure 9 and Figure 10 A central hole 522 is provided at the central position of the middle plate 520 of the air guiding mechanism 500, and the foregoing through holes 521 are arranged around the outside of the central hole 522. At the same time, refer to Figure 8, a through hole 430 is provided at the central position of the lower cyclone cone mechanism 400, and the foregoing dust discharge holes 420 are arranged around the outside of the through hole 430. After the central column 320 of the upper cyclone cone mechanism 300 passes downward through the central hole 522 and the through hole 430, it communicates with the top end of the inner cylinder 710. The side of the central column 320 is open to communicate with the inside of the air guiding channel 330, and the substrate 630 of the exhaust mechanism 600 seals the top end of the air guiding channel 330. The airflow and dust mixture flowing in from the mixture inlet 711 flow upward through the central column 320, enter the air guiding channel 330, and flow from the center to the edge in the air guiding channel 330. The air guiding channel 330 is spiral, and its outside extends tangentially along the central column 320, so that the airflow and dust mixture flowing into the primary dust collection chamber 110 from the air guiding channel 330 forms a cyclone flowing around the entire cyclone separator. Refer to Figure 2 and Figure 5 , the filter net 200 is sleeved outside a part of the structure of the upper cyclone cone mechanism 300, a notch 210 is provided on the filter net 200, and the shape near the air guiding channel 330 in the upper cyclone cone mechanism 300 matches the notch 210 to close the notch 210, so that the inside and outside of the filter net 200 are separated, ensuring that the airflow and dust mixture flowing into the primary dust collection chamber 110 through the air guiding channel 330 can only reach its inside after passing through the filter net 200, so as to optimize the filtering effect.

[0095] Refer to Figure 4 and Figure 6 , further, the upper cyclone cone mechanism 300 has a wind guiding plate 331, and the outer end of the wind guiding plate 331 extends tangentially along the upper cyclone cone mechanism 300, thereby guiding the airflow and dust mixture flowing out of the air guiding channel 330 to form a cyclone flowing around the entire cyclone separator. Further, the outer edge of the wind guiding plate 331 extends to the outside of the filter net 200. In this way, the airflow and dust mixture can be better guided, and the backflow of dirt can be prevented.

[0096] Refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 , in some embodiments, the upper cyclone cone 310 has an upper cyclone chamber 311 and an upper air inlet 312 communicating with the upper cyclone chamber 311. The upper air inlet 312 is used for the airflow and dust reaching the inside of the filter net 200 to enter the upper cyclone chamber 311 tangentially. Refer to Figure 8, the lower cyclone cone 410 has a lower cyclone chamber 411 and a lower air inlet 412 communicating with the lower cyclone chamber 411. The lower air inlet 412 is used for the airflow and dust reaching the inner side of the filter net 200 to enter the lower cyclone chamber 411 tangentially. The upper air inlet 312, the lower air inlet 412, and the air guiding channel 330 are configured such that the swirling directions of the airflow in the upper cyclone chamber 311 and the lower cyclone chamber 411 are both opposite to the swirling direction in the primary dust collection chamber 110.

[0097] Specifically, in the upper cyclone cone 310, an upper inlet plate 313 extending tangentially along the upper cyclone chamber 311 is provided at the upper air inlet 312, so as to guide the airflow and dust flowing in at the upper air inlet 312 to form a cyclone around the upper exhaust pipe 610. Similarly, in the lower cyclone cone 410, a lower inlet plate 413 extending tangentially along the lower cyclone chamber 411 is provided at the lower air inlet 412, so as to guide the airflow and dust flowing in at the lower air inlet 412 to form a cyclone around the upper and lower air guiding parts 512. The aforementioned clamping block 4131 protrudes from the outer wall of one of the lower inlet plates 413. By designing the extending directions of the upper inlet plate 313, the lower inlet plate 413, and the air guiding plate 331, the swirling directions of the airflow in the upper cyclone chamber 311 and the lower cyclone chamber 411 are both opposite to the swirling direction in the primary dust collection chamber 110. Therefore, the large-particle dust in the primary dust collection chamber 110 is not easily reversed and rotated into the upper cyclone chamber 311 and the lower cyclone chamber 411 under the action of inertia, and can be better separated outside the filter net 200, thereby optimizing the separation effect.

[0098] Refer to Figure 3 , in some embodiments, the inner wall of the filter net 200 is tangent to the outer wall of the air guiding pipe 510. Such a setting can reduce the size of the filter net 200, thereby reducing the size of the entire cyclone separator.

[0099] Refer to Figures 7 to 8 , in some embodiments, a plurality of upper cyclone cones 310 are evenly distributed along the circumferential direction of the cyclone separator, and a plurality of lower cyclone cones 410 are evenly distributed along the circumferential direction of the cyclone separator.

[0100] Specifically, a plurality of upper cyclone cones 310 are evenly distributed along the circumferential direction of the cyclone separator outside the central column 320, and a plurality of lower cyclone cones 410 are evenly distributed along the circumferential direction of the cyclone separator outside the through hole 430. Making the upper cyclone cones 310 and the lower cyclone cones 410 both evenly distributed can enable the dust at each position to be evenly separated, thereby optimizing the separation effect.

[0101] Refer to Figure 3, in some embodiments, the cyclone separator further includes a first seal 910, a second seal 920, and a third seal 930. The first seal 910 is disposed between the intermediate plate 520 of the air guiding mechanism 500 and the lower cyclone cone mechanism 400 to improve the sealing performance therebetween. The second seal 920 is disposed between the bottom end of the through hole 430 of the lower cyclone cone mechanism 400 and the top end of the inner cylinder 710 of the cyclone hood 700 to improve the sealing performance therebetween. The third seal 930 is disposed between the top end of the upper cyclone cone mechanism 300 and the substrate 630 of the exhaust mechanism 600 to improve the sealing performance therebetween. It should be noted that in the foregoing embodiments, the components in the cyclone separator are fixedly connected, and the specific fixing method may be conventional methods such as snap connection, threaded fastener connection, welding, or bonding, which will not be elaborated herein.

[0102] Referring to Figures 1 to 3 , a dust collection device provided in an embodiment of the present application includes the cyclone separator in any one of the foregoing embodiments, and further includes a dust cup 100.

[0103] Specifically, the cyclone separator is disposed below the Hepa 800. An air inlet pipe 120 is provided at the bottom end of the dust cup 100. The air flow and dust mixture flows into the mixture inlet 711 from the air inlet pipe 120, and sequentially enters the primary dust collection chamber 110 outside the cyclone separator through the central column 320 and the air guiding channel 330. The air flow and dust rotating around the cyclone separator in the primary dust collection chamber 110 are filtered through the filter screen 200. Large-sized dust is deposited in the primary dust collection chamber 110, and small-sized dust and air flow pass through the filter screen 200 to reach the inside thereof, and are secondarily filtered by the upper cyclone cone mechanism 300 and the lower cyclone cone mechanism 400. After filtering, the dust is deposited in the secondary dust collection chamber 730, and the clean air flow flows upward through the Hepa 800 for filtering.

[0104] Referring to Figure 3 , in some embodiments, the dust collection device includes a fourth seal 940, a fifth seal 950, and a sixth seal 960. The fourth seal 940 is disposed between the bottom end outlet of the secondary dust collection chamber 730 of the cyclone hood 700 and the bottom wall of the dust cup 100, and the fourth seal 940 is sleeved outside the air inlet pipe 120 to improve the sealing performance here. The fifth seal 950 is disposed around between the bottom wall and the side wall of the dust cup 100 to improve the sealing performance here. The sixth seal 960 is disposed between the outside of the shroud 640 of the cyclone separator and the inner wall of the dust cup 100 to improve the sealing performance therebetween.

[0105] Referring to Figure 1 and Figure 13, in some embodiments, the dust cup 100 includes a dust cup bottom wall 130 and a cup body 140 that are rotatably connected. An air inlet pipe 120 for air flow and dust to enter is connected to the dust cup bottom wall 130. The dust cup bottom wall 130 forms the bottom surfaces of the aforementioned primary dust collection chamber 110 and secondary dust collection chamber 730.

[0106] The bottom end of the cup body 140 is open. The dust cup bottom wall 130 can rotate relative to the cup body 140 to pour out the garbage stored in the dust cup 100. When the cyclone separator 11 is exposed through the opening of the cup body 140, the cyclone separator 11 can be removed through this opening for cleaning.

[0107] Refer to Figure 13 and Figure 14 , in some embodiments, the dust collection device further includes a dust bag 10. The dust bag 10 and the cyclone separator 11 are selectively installed in the dust cup 100. The user can choose to install the dust bag 10 or the cyclone separator 11 into the dust cup 100 according to the usage requirements.

The motor 13 is communicated with the outlet of the dust collection device.

[0109] Specifically, the outlet of the dust collection device is located at its top end. The bottom end of the motor 13 is communicated with the top end of the dust collection device to provide a suction force to draw the air flow and dust mixture into the dust collection device through the air inlet pipe 120. The clean air flow filtered by the Hepa 800 flows into the motor 13 and is discharged to the outside from the air outlet of the motor 13.

[0110] Refer to Figure 16 , in some embodiments, the cleaning device includes a body 12 for installing the motor 13. The dust collection device is rotatably connected to the body 12.

[0111] Specifically, the motor 13 is fixedly installed inside the body 12. The dust cup 100 of the dust collection device is rotatably connected to the body 12. The top end of the dust cup 100 is also open. When the dust cup 100 rotates relative to the body 12 to expose the opening at the top end of the dust cup 100, the cyclone separator 11 inside it can be removed from the top opening.

[0112] After the dust cup 100 rotates to align with the body 12, the two can be fixed through a clamping structure. Any clamping structure in the prior art can be selected. For example, in the dust cup 100 and the body 12, one of them is provided with a hook and the other is provided with a groove, and the two are clamped with each other to connect and fix the dust cup 100 and the body 12.

[0113] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
