Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a cleaning device. BACKGROUND

[0002] A dust collector is a very popular household appliance. With the iterative update of dust collector technology, some dust collectors use dust bags for dust filtration, and dust is finally collected in the dust bag. Only the dust bag needs to be replaced to complete the dust pouring. Although the cleaning is relatively convenient, the cost is high, and therefore it is more commonly used in large cleaning scenarios with a large amount of dust. Some dust collectors use cyclone separators for dust filtration, and dust is finally collected in the dust cup. This type of filtration has high filtration efficiency and lower cost, but fine dust is easily accumulated in the dust cup, and it is more troublesome to pour dust. Therefore, it is more commonly used in daily cleaning scenarios with a small amount of dust. Since the above two filtering methods have advantages and disadvantages, in order to meet the use requirements of different scenes, many families need to purchase two machines, resulting in a high cleaning cost.

[0073] Referring to Figure 3 , Figure 13 , Figure 14 and Figure 18 , an embodiment of the present application provides a cleaning device including a body 12 and a dust collecting device, wherein the body 12 includes a main body for mounting a motor 13, and a hand-held portion 14 for a user to hold. The dust collecting device includes a dust cup 100, a cyclone separator 11 and a dust bag 10. The dust cup 100 includes a dust cup bottom wall 130 rotatably connected and a cup body 140, and the dust cup bottom wall 130 is connected with an air inlet pipe 120 extending into the dust cup 100, the air inlet pipe 120 is used for the mixture of air flow and dust to enter. The cyclone separator 11 can be installed in the dust cup 100 and is in butt joint with the air inlet pipe 120, so as to separate the garbage under the suction force of the motor 13. The dust bag 10 can be installed in the dust cup 100 and is in butt joint with the air inlet pipe 120, so as to collect the garbage in the dust bag 10 under the suction force of the motor 13.

[0074] The dust cup 100 is rotatably connected with the dust cup bottom wall 130 and the cup body 140, so that the two can be relatively rotated to an open state of the dust cup bottom wall 130 for dumping garbage, or the cyclone separator 11 or the dust bag 10 can be installed in the dust cup 100 according to different use scenarios. The air inlet pipe 120 extends into the dust cup 100, and the air inlet pipe 120 is connected with the cyclone separator 11 or the dust bag 10, so that the mixture of air flow and dust garbage can be sent into the corresponding separator for garbage separation in both modes. In summary, the cleaning equipment can select to install different separators according to different cleaning scenarios, so that it is not necessary to specially equip two machines, and the cleaning cost is lower.

[0075] In some embodiments, the cyclone separator 11, the dust cup bottom wall 130 and the cup body 140 surround a first dust collecting chamber 110, and the cyclone separator 11 is used to separate at least part of the garbage to the first dust collecting chamber 110 under the suction force of the motor 13.

[0076] Specifically, when the dust bag 10 separates dust garbage, it collects garbage in the bag through filtration, and the cyclone separator 11 collects at least part of the garbage outside the cyclone separator 11, i.e., between the outer wall of the cyclone separator 11 and the dust cup 100. Then when switching from the cyclone separator 11 to the dust bag 10, the dust cup bottom wall 130 is only needed to be relatively rotated to the cup body 140 to an open state, and the dust garbage collected in the first dust collecting chamber 110 will directly fall out, and then the dust bag 11 can be directly installed, which is relatively convenient to operate. When switching from the dust bag 10 to the cyclone separator 11, the dust cup bottom wall 130 is only needed to be relatively rotated to the cup body 140 to an open state, and the dust bag 10 is taken out or allowed to fall out under the weight, and then the garbage collected in the dust bag 10 can be dumped, and then the cyclone separator 11 can be directly installed, which is also relatively convenient to operate. Compared with the conventional cleaning equipment with a dust cup bottom wall 130 that cannot be opened, in the embodiment, the dust cup bottom wall 130 can be flipped to an open state to facilitate garbage dumping and replacement of the separator type.

[0077] Referring to Figure 3 , Figure 13 , Figure 14 and Figure 18An embodiment of this application provides a cleaning device including a body 12 and a dust collection device. The body 12 includes a main body for mounting a motor 13 and a handheld part 14 for a user to hold. The dust collection device includes a dust cup 100 and at least two dust separation mechanisms. Any dust separation mechanism can be selectively installed in the dust cup 100, including a cyclone separator 11 or a dust bag 10. The dust cup 100 includes a bottom wall 130 and a cup body 140 rotatably connected. An air inlet pipe 120 extending into the dust cup 100 is connected to the bottom wall 130. The outlet of the air inlet pipe 120 communicates with the inlet of the dust separation mechanism. A sealing part 940 is sleeved on the outside of the air inlet pipe 120. The sealing part 940 is abutted against the bottom wall 130 by the inlet end of the dust separation mechanism to seal the inlet of the dust separation mechanism and the outlet of the air inlet pipe 120.

[0078] In the aforementioned cleaning equipment, the dust cup 100's bottom wall 130 and cup body 140 are rotatably connected. Therefore, they can be rotated relative to each other until the bottom wall 130 opens for emptying dust, or the dust separation mechanism can be replaced according to different usage scenarios. Furthermore, the air inlet pipe 120 extends into the dust cup 100, and its outlet is connected to the inlet of the dust separation mechanism, allowing airflow and dust mixtures to be delivered to the dust separation mechanism for dust separation. A sealing part 940 is fitted onto the outside of the air inlet pipe 120, and this sealing part 940 is abutted against the bottom wall 130 of the dust cup by the inlet end of the dust separation mechanism. This seals the inlet of the dust separation mechanism and the outlet of the air inlet pipe 120, preventing air leakage. The airflow and dust mixture flowing in from the air inlet pipe 120 are all drawn into the dust separation mechanism by the suction force of the motor, ensuring a good separation effect. In summary, the above-mentioned cleaning equipment can be equipped with different dust separation mechanisms according to different cleaning scenarios, thus eliminating the need for two separate machines, resulting in lower cleaning costs. Furthermore, due to the sealing part 940, it can achieve better dust separation during the cleaning process.

[0079] See Figure 3 and Figure 18 In some embodiments, when the cyclone separator 11 is installed inside the dust cup 100, their central axes coincide; when the dust bag 10 is installed inside the dust cup 100, their central axes coincide. Thus, the positions of both dust separation mechanisms within the dust cup 100 are relatively centered, eliminating the need to specifically increase the radial dimension of the dust cup 100 for their installation, and facilitating the assembly and disassembly of the cyclone separator 11 and the dust bag 10.

[0080] See Figure 3 and Figure 18In some embodiments, when the cyclone separator 11 is installed in the dust cup 100, the central axis of the cyclone separator 11 coincides with the central axis of the air inlet pipe 120; when the dust bag 10 is installed in the dust cup 100, the central axis of the dust bag 10 coincides with the central axis of the air inlet pipe 120. In this way, the air flow and dust mixture drawn from the air inlet pipe 120 can have less fluid energy loss after entering the cyclone separator 11 or the dust bag 10, thereby having higher suction efficiency and separation efficiency.

[0081] Referring to Figure 3 , Figure 13 , Figure 14 and Figure 18 In some embodiments, the cyclone separator 11 and the dust bag 10 are both cylindrical, and have the same axial and radial dimensions.

[0082] Specifically, the cyclone separator 11 and the dust bag 10 are both cylindrical, and have the same axial and radial dimensions, so that the size of the dust cup 100 does not need to be enlarged for the replacement installation of the two, which is conducive to the miniaturization of the dust cup 100.

[0083] Referring to Figure 14 , Figure 17 and Figure 18 In some embodiments, the dust bag 10 includes a fixed end plate 101 and a bag body 102 connected to the side of the fixed end plate 101 away from the bottom wall 130 of the dust cup 100, the fixed end plate 101 is made of hard plastic, and the bag body 102 is made of soft material with air permeability, and the dust bag 10 is fixed in the dust cup 100 by the fixed end plate 101.

[0084] Specifically, the bag body 102 can be made of non-woven fabric or the like. After the air flow and dust mixture enter the dust bag 10, they will pass through the bag body 102 from the inside to the outside, thereby completing the filtration and separation, leaving dust particles and the like in the dust bag 10, and the clean air flow is sucked out of the dust collection device by the motor 13. The fixed end plate 101 is arranged at one end of the bag body 102 to block the opening of the bag body 102, thereby forming a closed space in the dust bag 10. The fixed end plate 101 is made of hard plastic, which facilitates the fixed installation of the dust bag 10.

[0085] In some embodiments, the bag body 102 is connected to the fixed end plate 101 by adhesion or sewing.

[0086] Referring to Figure 14 , Figure 17 and Figure 18In some embodiments, the inner side wall of the cup 140 is provided with a pressing portion 141, the bottom wall of the dust cup 130 is provided with a supporting portion 131, the fixed end plate 101 is supported on the supporting portion 131, and the pressing portion 141 is located on the side of the fixed end plate 101 away from the supporting portion 131 and presses the fixed end plate 101 against the supporting portion 131.

[0087] Specifically, the pressing portion 141 is arranged on the lower region of the inner side wall of the cup 140 and protrudes inwardly along the radial direction of the cup 140. The supporting portion 131 is arranged on the region close to the outer ring of the bottom wall of the dust cup 130 and protrudes upwardly from the bottom wall of the dust cup 130. The part of the fixed end plate 101 located outside the bag 102 extends into the space between the pressing portion 141 and the supporting portion 131 and is pressed against the supporting portion 131 by the pressing portion 141, thereby achieving the fixed installation of the dust bag 10. After the installation, the dust bag 10 will not be separated from the air inlet pipe 120 during the suction of the motor 13, thereby always maintaining the separation and filtration of dust.

[0088] In some embodiments, the pressing portion 141 is arranged on part of the inner side wall of the cup 140. In other embodiments, the entire annular region of the inner side wall of the cup 140 is entirely distributed with the pressing portion 141.

[0089] Similarly, in some embodiments, the supporting portion 131 is arranged on part of the bottom wall of the dust cup 130. In other embodiments, the entire annular region of the bottom wall of the dust cup 130 is entirely distributed with the supporting portion 131.

[0090] Referring to Figure 14 , Figure 17 and Figure 18 In some embodiments, the dust bag 10 comprises an air inlet end plate 103 connected to the inner side of the fixed end plate 101, the air inlet end plate 103 has an aperture 1031 communicating with the outlet of the air inlet pipe 120, the air inlet end plate 103 is supported on the sealing portion 940, and the pressing portion 141 presses the fixed end plate 101 against the supporting portion 131 so that the air inlet end plate 103 is pressed against the sealing portion 940.

[0091] Specifically, the fixed end plate 101 and the air inlet end plate 103 are connected by a curved plate, and the air inlet end plate 103 is provided with a hole in the center to form the aperture 1031. The airflow and dust mixture entering from the outlet of the air inlet pipe 120 will flow into the dust bag 10 through the aperture 1031 to complete the filtration and separation. The pressing portion 141 presses the fixed end plate 101 against the supporting portion 131, and at the same time, presses the air inlet end plate 103 against the aforementioned sealing portion 940, so that the sealing portion 940 abuts against the bottom wall of the dust cup 130, seals the space between the outlet of the air inlet pipe 120 and the aperture 1031 of the dust bag 10, and ensures that the airflow and dust mixture flow into the dust bag 10 through the aperture 1031 and are not easily leaked out of the dust bag 10.

[0092] Referring to Figure 17 and Figure 18 In some embodiments, the air inlet end plate 103 is provided with a protruding rib 1032, which abuts against the sealing portion 940. By providing the protruding rib 1032, the friction between the air inlet end plate 103 and the sealing portion 940 can be increased, so that the air inlet end plate 103 and the sealing portion 940 are less likely to move relative to each other.

[0093] Referring to Figure 17 and Figure 18 In some embodiments, a fifth sealing member 950 is provided between the dust cup bottom wall 130, the cup body 140 and the fixed end plate 101, so as to improve the sealing between the three. In this way, even if the sealing portion 940 is not effective, some of the airflow and dust mixture flowing from the air inlet pipe 120 can leak to the outside of the air inlet end plate 103. Since the fifth sealing member 950 is provided between the dust cup bottom wall 130, the cup body 140 and the fixed end plate 101, the airflow and dust mixture can be inhibited from flowing to the space between the dust bag 10 and the inner wall of the dust cup 100.

[0094] Referring to Figure 17 and Figure 18 In some embodiments, the region of the fifth sealing member 950 for abutting against the cup body 140 is located outside the pressing portion 141 and the supporting portion 131.

[0095] Specifically, the region of the fifth sealing member 950 for abutting against the cup body 140 is the top region of the fifth sealing member 950, which is located outside the pressing portion 141 and the supporting portion 131. The inner side wall of the fifth sealing member 950 abuts against the outer side wall of the supporting portion 131, the top wall of the fifth sealing member 950 abuts against the cup body 140, and the transition region between the top wall and the inner side wall of the fifth sealing member 950 abuts against the fixed end plate 101.

[0096] Referring to Figure 3 and Figure 16 In some embodiments, the dust collecting device is rotationally connected to the machine body 12.

[0097] Generally, the upper part of the cyclone separator 11 can have a large radial dimension, for example, the region of the cyclone separator 11 where the sixth sealing member 960 is provided can have a large radial dimension, which makes it inconvenient to disassemble the cyclone separator 11 from the bottom end of the dust cup 100. In the present embodiment, the top end of the dust cup 100 is open, and when the dust cup 100 is rotated relative to the machine body 12 to expose the opening at the top end of the dust cup 100, the cyclone separator 11 inside the dust cup 100 can be removed through the opening at the top end.

[0098] Referring to Figure 16In some embodiments, after the dust cup 100 is rotated to be aligned with the main body 12, the two can be fixed by a clamping structure. Any clamping structure in the prior art can be selected. For example, one of the dust cup 100 and the main body 12 is provided with a clamping 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 main body 12.

[0099] Referring to Figures 1 to 3 , and Figure 15 , the outlet of the dust collecting device is located at the top end thereof, the bottom end of the motor 13 is communicated with the top end of the dust collecting device to provide suction force, so that the air flow and the dust mixture are sucked into the dust collecting device through the air inlet pipe 120. The clean air flow filtered by the HEPA 800 flows into the motor 13 and is discharged from the air outlet of the motor 13 to the outside.

[0100] Referring to Figures 1 to 3 , an embodiment of the present application provides a cyclone separator for being installed in the dust cup 100 of the dust collecting device to separate the dust and the air flow entering the dust cup 100, so that the dust is separated out and collected in the dust cup 100, and the clean air flow flows out of the dust cup 100 after being filtered by the HEPA 800 to further improve the cleanliness and enters the motor 13.

[0101] Referring to Figures 2 to 4 , an embodiment of the present application provides a cyclone separator including a filter screen 200, an upper cyclone cone mechanism 300 and a lower cyclone cone mechanism 400. The outer wall of the filter screen 200 can form a first dust collecting chamber 110 between the inner wall of the dust cup 100, the cyclone separator has a mixture inlet 711 communicated with the air inlet pipe 120 for the air flow and the dust to enter, and the mixture inlet 711 is communicated with the first dust collecting chamber 110. Referring to Figures 6 to 8 , the upper cyclone cone mechanism 300 includes a plurality of upper cyclone cones 310 located inside the filter screen 200, and the lower cyclone cone mechanism 400 includes a plurality of lower cyclone cones 410 located inside the filter screen 200. The upper cyclone cone 310 is located on the side of the lower cyclone cone 410 away from the bottom wall 130 of the dust cup, and the radial dimension of the upper cyclone cone 310 is smaller than the radial dimension of the lower cyclone cone 410.

[0102] The cyclone separator is installed in the dust cup 100 of the dust collecting device. In the cyclone separator, the outer wall of the filter screen 200 can form a first dust collecting chamber 110 with the inner wall of the dust cup 100. The mixture inlet 711 for the mixture of air flow and dust entering the cyclone separator is communicated with the first dust collecting chamber 110. Therefore, the mixture of air flow and dust entering the cyclone separator will be filtered by the filter screen 200. The dust with large size is first separated and collected in the first dust collecting chamber 110 outside the filter screen 200, and the dust with slightly smaller size passes through the filter screen 200 to the inside of the filter screen 200 with the air flow. A plurality of upper cyclone cones 310 and a plurality of lower cyclone cones 410 are arranged in the inside of the filter screen 200. The upper cyclone cones 310 are located on the side of the lower cyclone cones 410 away from the bottom wall 130 of the dust cup, that is, in the use state, the upper cyclone cones 310 are located above the lower cyclone cones 410. The dust and air flow reaching the inside of the filter screen 200 will enter the upper cyclone cones 310 and the lower cyclone cones 410 to complete the second separation. The dust with large particles reaching the inside of the filter screen 200 will be located lower due to the gravity. Since the upper cyclone cones 310 are located above the lower cyclone cones 410, the dust with large particles will mainly flow into the lower cyclone cones 410 for cyclone separation, and the dust with small particles will mainly flow into the upper cyclone cones 310 for cyclone separation. According to the common knowledge in the art, the smaller the radial size of the cyclone cone is, the smaller the dust particles that can be separated are. Therefore, the radial size of the upper cyclone cone 310 is set to be smaller than the radial size of the lower cyclone cone 410, so that the dust with different sizes entering the upper cyclone cone 310 and the lower cyclone cone 410 can be better matched. Thus, the dust with different sizes can be separately subjected to the second separation on the basis of the first separation, so that a better separation effect can be achieved.

[0103] Referring to Figure 3 , Figure 4 , Figure 8 and Figure 9 In some embodiments, the cyclone separator comprises a wind guide mechanism 500 comprising a plurality of wind guide pipes 510. One end of each wind guide pipe 510 is inserted into a corresponding lower cyclone cone 410, and the other end of each wind guide pipe 510 passes through the upper cyclone mechanism 300. The wind guide pipes 510 are used to discharge the clean air flow separated by the lower cyclone cones 410.

[0104] Specifically, the air guide mechanism 500 is located inside the filter screen 200, and the bottom end of each air guide pipe 510 is inserted into a corresponding lower cyclone cone 410, and the top end is inserted into the upper cyclone mechanism 300. The lower cyclone cone 410 has a lower cyclone cavity 411, and the lower cyclone cavity 411 has a lower air inlet 412. The dust and airflow passing through the filter screen 200 to the lower part of the inside of the filter screen 200 can flow into the lower cyclone cavity 411 from the lower air inlet 412 in a tangential direction. The bottom end of the air guide pipe 510 is inserted into the lower cyclone cone 410, so that the dust and airflow flowing into the lower cyclone cavity 411 will rotate around the air guide pipe 510, thereby realizing cyclone separation. The separated clean airflow is discharged upwards through the air guide pipe 510, and the dust is deposited downwards. The hepa 800 is located above the air guide pipe 510, and the clean airflow discharged upwards from the top end of the air guide pipe 510 will flow into the hepa 800 for filtration. In the embodiment shown in the drawings, six lower cyclone cones 410 are provided, so that six air guide pipes 510 matched therewith are provided at corresponding positions.

[0105] Referring to Figure 9 In some embodiments, the plurality of air guide pipes 510 are integrally connected by an integral molding method. Specifically, the air guide mechanism 500 includes a middle plate 520, and the plurality of air guide pipes 510 are connected to the middle plate 520.

[0106] Referring to Figure 4 , Figure 8 and Figure 9 In some embodiments, one of the air guide mechanism 500 and the lower cyclone mechanism 400 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.

[0107] Specifically, the air guide mechanism 500 includes a flange 530 folded downward from the outer edge of the middle plate 520, and the flange 530 has a clamping groove 531, and the lower cyclone mechanism 400 has a clamping block 4131. By clamping the clamping block 4131 into the clamping groove 531, the connection and fixation between the air guide mechanism 500 and the lower cyclone mechanism 400 can be achieved.

[0108] Referring to Figure 3 , Figure 4 , Figure 6 , Figure 8 and Figure 9 In some embodiments, the air guide pipe 510 includes a lower air guide part 512 inserted into the lower cyclone cone 410, and an upper air guide part 511 passing through the upper cyclone mechanism 300. The upper air guide part 511 and the upper cyclone 310 are positionally staggered, the lower air guide part 512 and the upper air guide part 511 are in communication, and the central axes of the two do not coincide.

[0109] Specifically, the lower air guide part 512 is connected to the bottom end of the upper air guide part 511, and the interiors of the two are communicated for the airflow to pass through. The upper air guide part 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 hollow holes 340 are staggered with the positions of the upper cyclone cones 310. Each of the hollow holes 340 is used for the corresponding upper air guide part 511 to pass through. Meanwhile, referring to Figure 10 The lower air guide part 512 passes through the middle plate 520, that is, the bottom end part of the lower air guide part 512 extends downward from the middle plate 520, and the top end part of the lower air guide part 512 extends upward from the middle plate 520. The top end part of the lower air guide part 512 is communicated with the upper air guide part 511. The lower air guide part 512 and the upper air guide part 511 are both columnar tubes, and the central axes of the two do not coincide. Further, the central axis of the lower air guide part 512 is closer to the central region of the middle plate 520 than the central axis of the upper air guide part 511, that is, the central axis of the lower air guide part 512 is located inside the central axis of the upper air guide part 511.

[0110] In the above embodiment, the central axes of the lower air guide part 512 and the upper air guide part 511 are arranged not to coincide, so that the air guide tube 510 can be arranged just in the gap inside the filter screen 200 other than the upper cyclone cone mechanism 300 and the lower cyclone cone mechanism 400. Therefore, the space inside the filter screen 200 does not need to be increased for arranging the air guide tube 510, that is, the size of the filter screen 200 does not need to be increased, which is beneficial to the size reduction of the cyclone separator. When the cyclone separator is arranged 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.

[0111] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 12 In some embodiments, the cyclone separator comprises an exhaust mechanism 600 arranged at the air inlet side of the dust collection device. The exhaust mechanism 600 comprises a plurality of upper exhaust tubes 610 and a plurality of lower exhaust tubes 620. Each of the upper exhaust tubes 610 is inserted into the corresponding upper cyclone cone 310 for exhausting the clean airflow separated by the upper cyclone cone 310. Each of the lower exhaust tubes 620 is inserted into the corresponding air guide tube 510.

[0112] Specifically, the exhaust mechanism 600 comprises 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 end of the upper cyclone cone mechanism 300 is recessed downward, the exhaust mechanism 600 is placed in the recess, and is located above the upper cyclone cone 310 and the air duct 510, the upper exhaust pipe 610 and the lower exhaust pipe 620 both protrude downward from the base plate 630. The upper cyclone cone 310 has an upper cyclone cavity 311, the upper cyclone cavity 311 has an upper air inlet 312, and the dust and airflow reaching the upper inside of the upper air inlet 312 through the filter screen 200 can flow into the upper cyclone cavity 311 along the tangential direction. The upper exhaust pipe 610 is inserted into the corresponding upper cyclone cone 310, so that the dust and airflow flowing into the upper cyclone cavity 311 will rotate around the upper exhaust pipe 610, thereby realizing cyclone separation. The separated clean airflow 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 separated clean airflow in the corresponding lower cyclone cone 410 is sequentially discharged upward through the air duct 510 and the lower exhaust pipe 620. The positions corresponding to the upper exhaust pipe 610 and the lower exhaust pipe 620 on the base plate 630 are provided with through holes, so that the airflow discharged from the top end of the upper exhaust pipe 610 and the lower exhaust pipe 620 can pass through the base plate 630 into the hepa 800.

[0113] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 11 In some embodiments, the cyclone separator comprises a cyclone cover 700, the cyclone cover 700 comprises an inner cylinder 710 and an outer cylinder 720 arranged on the outside of the inner cylinder 710, a two-stage dust collecting chamber 730 is formed between the inner cylinder 710 and the outer cylinder 720, and the bottom end of each lower cyclone cone 410 is inserted into the two-stage dust collecting chamber 730 to discharge the separated dust into the two-stage dust collecting chamber 730.

[0114] Specifically, the inner cylinder 710 and the outer cylinder 720 are integrated, a conical two-stage dust collecting chamber 730 is formed between the two, the two-stage dust collecting chamber 730 and the aforementioned first-stage dust collecting chamber 110 are respectively located on the inner and outer sides of the outer cylinder 720. The bottom end of each lower cyclone cone 410 is inserted into the two-stage dust collecting chamber 730 downward, and the dust separated by each lower cyclone cone 410 falls into the two-stage dust collecting chamber 730 downward, thereby realizing dust collection.

[0115] Referring to Figure 3 , Figure 8 and Figure 11 In some embodiments, the end of the lower cyclone cone 410 away from the corresponding air duct 510 is inclined to the side close to the central axis of the cyclone separator.

[0116] Specifically, the lower cyclone cone 410 is inclined towards the side close to the inner cylinder 710 from the end of the corresponding air duct 510. That is, the bottom end of the lower cyclone cone 410 is inclined towards the inner side, so that the outer cylinder 720 can also be inclined towards the inner side as much as possible to increase the space of the primary dust collecting chamber 110.

[0117] 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°.

[0118] Referring to Figure 3 , Figure 8 and Figure 11 In some embodiments, the outer cylinder 720 has multiple regions protruding towards the outer side to form protrusions 721, and the inner side of each protrusion 721 is used to accommodate one lower cyclone cone 410, and the shapes and sizes of the two are adapted to fit each other.

[0119] Specifically, the number of protrusions 721 matches the number and positions of the lower cyclone cones 410. After the protrusions 721 are formed, the inner wall and the outer wall of the protrusions 721 both protrude outward, the inner wall is inclined, can match the shape of the inclined outer surface of the lower cyclone cone 410, better accommodate the lower cyclone cone 410, and this inclined arrangement is conducive to reducing the length of the entire dust cup 100. In addition, the outer wall of the protrusion 721 is outwardly convex, which can reduce the rotational motion of large-particle garbage and hair deposited in the primary dust collecting chamber 110, so that they are stably kept at the bottom of the primary dust collecting chamber 110, and the outer walls of adjacent protrusions 721 form a recessed area therebetween, which can be used to remove hair wound around the outer wall of the protrusion 721 through the recessed area.

[0120] Referring to Figure 6 , Figures 8 to 10 In some embodiments, the lower cyclone cone mechanism 400 has multiple dust discharge holes 420 communicating with the secondary dust collecting chamber 730, the dust discharge holes 420 and the lower cyclone cones 410 are staggered in position, and each upper cyclone cone 310 close to one end of the lower cyclone cone mechanism 400 communicates with a corresponding dust discharge hole 420 to discharge the separated dust into the secondary dust collecting chamber 730 through the dust discharge hole 420.

[0121] Specifically, the dust discharge holes 420 pass through the lower cyclone cone mechanism 400 from top to bottom to communicate with the secondary dust collecting chamber 730. The middle plate 520 of the air guide mechanism 500 is provided with multiple through holes 521, the bottom end of each upper cyclone cone 310 is inserted into a corresponding through hole 521, and 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 communicates with the corresponding dust discharge hole 420 through the through hole 521. The dust separated by each upper cyclone cone 310 falls into the secondary dust collecting chamber 730 in turn through the hole 521 and the dust discharge hole 420, thereby realizing dust collection.

[0122] Referring to Figure 3 with Figure 7 In some embodiments, the upper cyclone cone 310 is inclined towards the side close to the central axis of the cyclone separator at the end close to the lower cyclone cone mechanism 400.

[0123] Specifically, the upper cyclone cone 310 is inclined towards the side close to the inner cylinder 710 at the end close to the lower cyclone cone mechanism 400. That is, the bottom end of the upper cyclone cone 310 is inclined inwards, so that the bottom end of the upper cyclone cone 310 can be aligned with the dust outlet holes 420 located at the gaps between the lower cyclone cones 410, thereby making more efficient use of space and making the structure more compact.

[0124] 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°.

[0125] Referring to Figure 3 , Figure 4 , Figure 6 with Figure 7 In some embodiments, the inner side of the inner cylinder 710 forms a mixture inlet 711, the upper cyclone cone mechanism 300 includes a central column 320 connected to the inner cylinder 710, and an air guide channel 330 connected to the central column 320, and a plurality of upper cyclone cones 310 are distributed on the outer side of the central column 320, the air guide channel 330 is spiral and extends from the center to the edge of the upper cyclone cone mechanism 300, and the airflow and dust flowing into the mixture inlet 711 can enter the primary dust collecting chamber 110 through the central column 320 and the air guide channel 330 in sequence.

[0126] Specifically, the inner cylinder 710 is located at the center of the entire cyclone separator, and the airflow and dust mixture flows into the cyclone separator from the bottom end of the inner cylinder 710 through the mixture inlet 711. Referring to Figure 9 and Figure 10 , the central hole 522 is provided at the center of the middle plate 520 of the air guide mechanism 500, and each through hole 521 is arranged around the outside of the central hole 522. Referring to Figure 8The center of the lower cyclone cone mechanism 400 is provided with a through hole 430, and the various dust discharge holes 420 are arranged around the outside of the through hole 430. The center column 320 of the upper cyclone cone mechanism 300 passes through the center hole 522 and the through hole 430 downward, and is in communication with the top end of the inner cylinder 710. The side of the center column 320 is open to communicate with the inner side of the air guide channel 330, and the base plate 630 of the exhaust mechanism 600 blocks the top end of the air guide channel 330. The airflow and dust mixture flowing from the mixture inlet 711 flow upward through the center column 320, enter the air guide channel 330, and flow from the center to the edge in the air guide channel 330. The air guide channel 330 is spiral-shaped, and the outer side extends along the tangential direction of the center column 320, so that the airflow and dust mixture flowing from the air guide channel 330 into the primary dust collecting chamber 110 forms a cyclone that flows around the entire cyclone separator. See also Figure 2 and Figure 5 The filter screen 200 is sleeved on part of the structure of the upper cyclone cone mechanism 300, and the filter screen 200 is provided with a notch 210. The shape of the air guide channel 330 in the upper cyclone cone mechanism 300 matches the notch 210, so as to close the notch 210, so that the inner and outer sides of the filter screen 200 are separated, so as to ensure that the airflow and dust mixture flowing through the air guide channel 330 into the primary dust collecting chamber 110 can only reach the inner side of the filter screen 200 after being filtered by the filter screen 200, so as to optimize the filtering effect.

[0127] See Figure 4 and Figure 6 Further, the upper cyclone cone mechanism 300 has an air guide plate 331, and the outer end of the air guide plate 331 extends along the tangential direction of the upper cyclone cone mechanism 300, so as to guide the airflow and dust mixture flowing out of the air guide channel 330, so that it forms a cyclone that flows around the entire cyclone separator. Further, the outer edge of the air guide plate 331 extends to the outside of the filter screen 200. In this way, the airflow and dust mixture can be better guided, and backflow of dirt can be prevented.

[0128] See Figure 3 , Figure 4 , Figure 6 and Figure 7 In some embodiments, the upper cyclone cone 310 has an upper cyclone cavity 311, and an upper air inlet 312 in communication with the upper cyclone cavity 311. The upper air inlet 312 is used for the airflow and dust reaching the inner side of the filter screen 200 to enter the upper cyclone cavity 311 along the tangential direction. See Figure 8The lower cyclone cone 410 has a lower cyclone chamber 411, and a lower air inlet 412 which is communicated with the lower cyclone chamber 411, and is used for tangentially introducing the airflow and dust arriving at the inside of the filter screen 200 into the lower cyclone chamber 411. The upper air inlet 312, the lower air inlet 412 and the air guide passage 330 are configured such that the rotation directions of the airflow in the upper cyclone chamber 311 and the lower cyclone chamber 411 are opposite to the rotation direction in the primary dust collecting chamber 110.

[0129] Specifically, in the upper cyclone cone 310, an upper inlet plate 313 extending tangentially along the upper cyclone chamber 311 is arranged at the upper air inlet 312, so as to guide the airflow and dust flowing into the upper air inlet 312 to form a cyclone around the upper air outlet pipe 610. Similarly, in the lower cyclone cone 410, a lower inlet plate 413 extending tangentially along the lower cyclone chamber 411 is arranged at the lower air inlet 412, so as to guide the airflow and dust flowing into the lower air inlet 412 to form a cyclone around the upper-lower air guide part 512. The aforementioned clamping block 4131 is protruded from the outer wall of one of the lower inlet plates 413. The extension directions of the upper inlet plate 313, the lower inlet plate 413 and the air guide plate 331 are designed such that the rotation directions of the airflow in the upper cyclone chamber 311 and the lower cyclone chamber 411 are opposite to the rotation direction in the primary dust collecting chamber 110. Therefore, the large-particle dust in the primary dust collecting chamber 110 is less likely to rotate reversely and enter the upper cyclone chamber 311 and the lower cyclone chamber 411 under the action of inertia, and can be better separated outside the filter screen 200, so as to optimize the separation effect.

[0130] Referring to Figure 3 In some embodiments, the inner wall of the filter screen 200 is tangent to the outer wall of the air guide pipe 510. In this way, the size of the filter screen 200 can be reduced, so as to reduce the size of the entire cyclone separator.

[0131] Referring to Figures 7 to 8 In some embodiments, the plurality of upper cyclone cones 310 are uniformly distributed along the circumference of the cyclone separator, and the plurality of lower cyclone cones 410 are uniformly distributed along the circumference of the cyclone separator.

[0132] Specifically, the plurality of upper cyclone cones 310 are uniformly distributed outside the central column 320 along the circumference of the cyclone separator, and the plurality of lower cyclone cones 410 are uniformly distributed outside the through hole 430 along the circumference of the cyclone separator. The uniform distribution of the upper cyclone cones 310 and the lower cyclone cones 410 can make the dust at each position be uniformly separated, so as to optimize the separation effect.

[0133] Referring to Figure 3In some embodiments, the cyclone separator further comprises a first seal 910, a second seal 920 and a third seal 930. The first seal 910 is arranged between the intermediate plate 520 of the air guide mechanism 500 and the lower cyclone cone mechanism 400 to improve the sealing therebetween. The second seal 920 is arranged 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 cover 700 to improve the sealing therebetween. The third seal 930 is arranged between the top end of the upper cyclone cone mechanism 300 and the base plate 630 of the exhaust mechanism 600 to improve the sealing therebetween. It should be noted that in the foregoing embodiments, the various components in the cyclone separator are fixedly connected, and the specific fixing manner can be a conventional manner such as clamping, threaded fastener connection, welding or bonding, which will not be described here.

[0134] Referring to Figures 1 to 3 The cyclone separator is arranged below the HEPA 800, and the airflow and dust mixture flows into the mixture inlet 711 from the air inlet pipe 120, sequentially passes through the center column 320 and the air guide channel 330, and then enters the first-stage dust collection chamber 110 outside the cyclone separator. The airflow and dust rotating around the cyclone separator in the first-stage dust collection chamber 110 are filtered by the filter screen 200, and the large-size dust is deposited in the first-stage dust collection chamber 110. The small-size dust and the airflow pass through the filter screen 200 to the inside of the first-stage dust collection chamber 110, are subjected to secondary filtration by the upper cyclone cone mechanism 300 and the lower cyclone cone mechanism 400, and after filtration, the dust is deposited in the second-stage dust collection chamber 730, and the clean airflow flows upwards through the HEPA 800 for filtration.

[0135] Referring to Figure 3 In some embodiments, the dust collection device comprises a sixth seal 960. The sixth seal 960 is arranged between the outer wall of the cyclone separator and the inner wall of the dust cup 100 to improve the sealing therebetween.

[0136] Any combination of the technical features in the above-described embodiments can be made, and to make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, however, as long as the combination of the technical features does not exist, it should be considered that it is within the scope of the description.
