Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly to cleaning equipment. Background Art

[0002] Vacuum cleaners are a very popular type of household appliance. With the iterative update of vacuum cleaner technology, some current vacuum cleaners use dust bags for dust filtration, and the dust is ultimately collected in the dust bag. One can simply replace the dust bag to complete the ash dumping. Although the cleaning is relatively convenient, the cost is relatively high. Therefore, it is more commonly used in scenarios with a large amount of dust such as spring cleaning. Some vacuum cleaners use a cyclone separator for dust filtration, and the dust is ultimately collected in the dust cup. This type of filtration method has a high filtration efficiency and lower cost. However, fine ash is likely to accumulate in the dust cup, and it is rather troublesome to dump the ash. Therefore, it is more commonly used in daily cleaning scenarios with a small amount of dust. Since the above two filtration methods each have their own advantages and disadvantages, in order to meet the usage requirements of different scenarios, many families need to purchase two machines, resulting in a relatively high cleaning cost. Utility Model Content

Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and 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.

[0072] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the 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 there is a term "plural", the meaning of "plural" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0073] In the present application, unless otherwise clearly specified and limited, if there are terms such as "installation", "connection", "connection", "fixation", etc., these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements or the interaction relationship between two elements, unless otherwise clearly limited.

[0075] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or there may 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", "upper", "lower", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0076] Refer to Figure 3 , Figure 13 , Figure 14 and Figure 18 , a cleaning device provided by an embodiment of the present application includes a body 12 and a dust collection device. Among them, the body 12 includes a main body for installing a motor 13 and a hand-held part 14 for the user to hold. The dust collection device includes a dust cup 100, a cyclone separator 11 and a dust bag 10. The dust cup 100 includes a rotatably connected dust cup bottom wall 130 and a cup body 140. An air inlet pipe 120 extending into the dust cup 100 is connected to the dust cup bottom wall 130. The air inlet pipe 120 is used for allowing a mixture of air flow and dust to enter. The cyclone separator 11 can be installed in the dust cup 100 and is docked with the air inlet pipe 120 to separate garbage under the suction force of the motor 13. The dust bag 10 can be installed in the dust cup 100 and is docked with the air inlet pipe 120 to collect garbage in the dust bag 10 under the suction force of the motor 13.

[0077] In the above-mentioned cleaning device, the bottom wall 130 of the dust cup 100 is rotatably connected to the cup body 140. Therefore, the two can be rotated relative to each other until the bottom wall 130 of the dust cup is opened for dumping garbage, or according to the requirements of different usage scenarios, the cyclone separator 11 or the dust bag 10 can be selected to be installed in the dust cup 100. The air inlet pipe 120 extends into the dust cup 100, and the air inlet pipe 120 is docked with the cyclone separator 11 or the dust bag 10, so that the air flow and dust garbage mixture can be sent into the corresponding separator for garbage separation in both modes. In summary, the above-mentioned cleaning device can select different separators according to different cleaning scenarios, so that there is no need to specially equip two machines, and the cleaning cost is lower.

[0078] In some embodiments, a primary dust collection chamber 110 is defined among the cyclone separator 11, the bottom wall 130 of the dust cup, and the cup body 140. The cyclone separator 11 is configured to separate at least part of the garbage into the primary dust collection chamber 110 under the suction force of the motor 13.

[0079] Specifically, when the dust bag 10 separates dust and garbage, the garbage is collected in the bag by filtration, while the cyclone separator 11 collects at least part of the garbage outside it, that is, between its outer wall and the dust cup 100. Then when switching from the cyclone separator 11 to the dust bag 10, only need to turn the bottom wall 130 of the dust cup relative to the cup body 140 to the open state, and the dust and garbage collected in the primary dust collection chamber 110 will directly fall out. After that, the dust bag 11 can be directly installed, and the operation is relatively convenient. When switching from the dust bag 10 to the cyclone separator 11, only need to turn the bottom wall 130 of the dust cup relative to the cup body 140 to the open state, take out the dust bag 10, or let it fall out under its own weight, and the garbage collected in it can be poured out together. After that, the cyclone separator 11 can be directly installed, and the operation is also relatively convenient. Compared with the conventional cleaning device with a non-openable bottom wall 130 of the dust cup, in this embodiment, the bottom wall 130 of the dust cup can be turned over and opened, which is convenient for dumping garbage and changing the type of separator.

[0080] Refer to Figure 3 、 Figure 13 、 Figure 14 And Figure 18, a cleaning device provided by an embodiment of the present application includes a body 12 and a dust collection device. Among them, the body 12 includes a main body for installing a motor 13 and a handheld part 14 for the user to hold. The dust collection device includes a dust cup 100 and at least two types of dust separation mechanisms. Any one of the dust separation mechanisms can be selectively installed in the dust cup 100. The dust separation mechanism includes a cyclone separator 11 or a dust bag 10. The dust cup 100 includes a rotatably connected dust cup bottom wall 130 and a cup body 140. An air inlet pipe 120 extending into the dust cup 100 is connected to the dust cup bottom wall 130. The outlet of the air inlet pipe 120 is communicated with the inlet of the dust separation mechanism. A sealing part 940 is sleeved outside the air inlet pipe 120. The sealing part 940 is abutted against the dust cup bottom wall 130 by the inlet end of the dust separation mechanism to seal between the inlet of the dust separation mechanism and the outlet of the air inlet pipe 120.

[0081] For the above cleaning device, the dust cup bottom wall 130 and the cup body 140 of the dust cup 100 are rotatably connected. Therefore, the two can be rotated relative to each other until the dust cup bottom wall 130 is opened for ash dumping, or the dust separation mechanism can be replaced according to different usage scenario requirements. In addition, the air inlet pipe 120 extends into the dust cup 100, and the outlet of the air inlet pipe 120 is communicated with the inlet of the dust separation mechanism, so that the air flow and dust mixture can be sent into the dust separation mechanism for dust separation. A sealing part 940 is sleeved outside the air inlet pipe 120, and the sealing part 940 is abutted against the dust cup bottom wall 130 by the inlet end of the dust separation mechanism, so that sealing can be carried out between the inlet of the dust separation mechanism and the outlet of the air inlet pipe 120, ensuring that air leakage is not easy between the two. The air flow and dust mixture flowing in from the air inlet pipe 120 can all enter the dust separation mechanism under the suction force of the motor to ensure a better separation effect. In summary, for the above cleaning device, different dust separation mechanisms can be selectively installed according to different cleaning scenarios, so that there is no need to specially equip two machines, and the cleaning cost is lower. And due to the setting of the sealing part 940, a better dust separation effect can be achieved during the cleaning process.

[0082] Refer to Figure 3 And Figure 18 , in some embodiments, when the cyclone separator 11 is installed in the dust cup 100, their central axes coincide; when the dust bag 10 is installed in the dust cup 100, their central axes coincide. In this way, the positions of the two dust separation mechanisms in the dust cup 100 are relatively centered, there is no need to specifically increase the radial size of the dust cup 100 for installing the two, and the disassembly and assembly of the cyclone separator 11 and the dust bag 10 can be facilitated.

[0083] Refer to Figure 3 And Figure 18, in 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. With such a setting, the fluid energy loss of the air flow and dust mixture drawn in from the air inlet pipe 120 is smaller after entering the cyclone separator 11 or the dust bag 10, so as to have higher suction efficiency and separation efficiency.

[0084] Refer to Figure 3 , Figure 13 , Figure 14 and Figure 18 , in some embodiments, both the cyclone separator 11 and the dust bag 10 are columnar, and their dimensions along the axial and radial directions of the dust cup 100 are the same.

[0085] Specifically, both the cyclone separator 11 and the dust bag 10 are cylindrical. When their axial dimensions are set to be the same and their radial dimensions are set to be the same, there is no need to enlarge the size of the dust cup 100 to accommodate the replacement installation of the two, which is beneficial to the miniaturization of the dust cup 100.

[0086] Refer 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 facing away from the bottom wall 130 of the dust cup. The material of the fixed end plate 101 is hard plastic, and the material of the bag body 102 is a breathable soft material. The dust bag 10 is fixed in the dust cup 100 through the fixed end plate 101.

[0087] Specifically, the bag body 102 can be made of materials such as non-woven fabric. After the air flow and dust mixture enter the dust bag 10, it will pass through the bag body 102 from the inside to the outside, so as to complete 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. By setting a fixed end plate 101 at one end of the bag body 102, the opening of the bag body 102 can be blocked, so as to form a closed space in the dust bag 10. And the fixed end plate 101 is made of hard plastic, which is convenient for the fixed installation of the dust bag 10.

[0088] In some embodiments, the bag body 102 is connected to the fixed end plate 101 by bonding or sewing.

[0089] Refer to Figure 14 , Figure 17 and Figure 18In some embodiments, a clamping portion 141 is convexly provided on the inner wall of the cup body 140, a supporting portion 131 is convexly provided on the bottom wall 130 of the dust cup, the fixed end plate 101 is supported on the supporting portion 131, the clamping 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.

[0090] Specifically, the pressing portion 141 is disposed in the lower area on the inner wall of the cup body 140, and protrudes radially inward from the inner wall of the cup body 140. The supporting portion 131 is disposed in the area close to the outer ring on the bottom wall 130 of the dust cup, and protrudes upward from the bottom wall 130 of the dust cup. The portion of the fixed end plate 101 located outside the bag body 102 extends 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 fixed installation of the dust bag 10. After installation in this way, when the motor 13 is suctioning, the dust bag 10 will not be separated from the connection with the air inlet pipe 120 due to the suction force of the motor 13, thereby always maintaining separation and filtration of dust.

[0091] In some embodiments, the pressing portion 141 is disposed in a partial area of ​​the inner side wall of the cup body 140. In other embodiments, the pressing portion 141 is distributed in the entire annular area of ​​the inner side wall of the cup body 140.

[0092] Similarly, in some embodiments, the support portion 131 is disposed in a partial area of ​​the dust cup bottom wall 130. In other embodiments, the entire annular area of ​​the dust cup bottom wall 130 is distributed with the support portion 131.

[0093] See also Figure 14 , Figure 17 and Figure 18 In some embodiments, the dust bag 10 includes an air inlet end plate 103 connected to the inner side of the fixed end plate 101, and the air inlet end plate 103 has an orifice 1031 connected to 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.

[0094] Specifically, the fixed end plate 101 and the air inlet end plate 103 are connected by a curved plate, and a hole is opened at the center of the air inlet end plate 103 to form an orifice 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 orifice 1031 to complete filtering and separation. The pressing part 141 presses the fixed end plate 101 against the support part 131, and also presses the air inlet end plate 103 against the aforementioned sealing part 940, so that the sealing part 940 abuts against the bottom wall 130 of the dust cup, and seals between the outlet of the air inlet pipe 120 and the orifice 1031 of the dust bag 10, ensuring that the airflow and dust mixture all flow into the dust bag 10 through the orifice 1031, and is not easily leaked out of the dust bag 10.

[0095] Refer to Figure 17 and Figure 18 , in some embodiments, the air inlet end plate 103 is provided with a rib 1032, and the rib 1032 abuts against the sealing portion 940. By providing the raised rib 1032, the frictional force between the air inlet end plate 103 and the sealing portion 940 can be increased, so that the relative displacement between the two is not likely to occur.

[0096] Refer to Figure 17 and Figure 18 , in some embodiments, a fifth seal 950 is provided between the bottom wall 130 of the dust cup, the cup body 140 and the fixed end plate 101 to improve the sealing performance among the three. In this way, even if the sealing effect of the sealing portion 940 is not good and part of the air flow-dust mixture flowing in from the air inlet pipe 120 leaks to the outside of the air inlet end plate 103, due to the fifth seal 950 provided between the bottom wall 130 of the dust cup, the cup body 140 and the fixed end plate 101, the flow of the air flow-dust mixture to the space between the dust bag 10 and the inner wall of the dust cup 100 can be inhibited.

[0097] Refer to Figure 17 and Figure 18 , in some embodiments, the area of the fifth seal 950 for abutting against the cup body 140 is located outside the pressing portion 141 and the supporting portion 131.

[0098] Specifically, the area of the fifth seal 950 for abutting against the cup body 140 is the top area of the fifth seal 950, and this area is located outside the pressing portion 141 and the supporting portion 131. The inner side wall of the fifth seal 950 abuts against the outer side wall of the supporting portion 131, the top wall of the fifth seal 950 abuts against the cup body 140, and the transition area between the top wall and the inner side wall of the fifth seal 950 abuts against the fixed end plate 101.

[0099] Refer to Figure 3 and Figure 16 , in some embodiments, the dust collecting device is rotatably connected to the machine body 12.

[0100] Generally, the radial dimension of the upper part of the cyclone separator 11 may be larger. For example, the radial dimension of the area where the sixth seal 960 is provided in the cyclone separator 11 is larger, which makes it inconvenient to disassemble and assemble the cyclone separator 11 from the bottom end of the dust cup 100. In this embodiment, the top end of the dust cup 100 is open. When the dust cup 100 rotates relative to the machine 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.

[0101] Refer to Figure 16, in some embodiments, after the dust cup 100 rotates to align with the body 12, the two can be fixed through a snap-fit structure. Any snap-fit structure in the prior art can be selected. For example, in the dust cup 100 and the body 12, a snap hook is provided on one of them, and a groove is provided on the other. The two are snap-fitted with each other to connect and fix the dust cup 100 and the body 12.

[0102] Refer to Figures 1 to 3 , and Figure 15 , the outlet of the dust collection device is located at its top end. The bottom end of the motor 13 communicates with the top end of the dust collection device to provide suction force, and the air flow and dust mixture are drawn into the dust collection device through the air inlet pipe 120. The clean air flow after being filtered by the HEPA 800 flows into the motor 13 and is discharged to the outside from the air outlet of the motor 13.

[0103] 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 flows out of the dust cup 100 after being filtered by the HEPA 800 to further improve the cleanliness and then enters the motor 13.

[0104] 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. 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 cyclone separator has a mixture inlet 711 communicating with the air inlet pipe 120 for the air flow and dust to enter, 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 located inside the filter net 200, and the lower cyclone cone mechanism 400 includes a plurality of lower cyclone cones 410 located inside the filter net 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, and the radial dimension of the upper cyclone cones 310 is smaller than the radial dimension of the lower cyclone cones 410.

[0105] The above-mentioned cyclone separator is installed inside 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 will 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, completing the primary separation. The dust with slightly smaller size passes through the filter net 200 with the air flow and reaches the inner side thereof. A plurality of upper cyclone cones 310 and a plurality of lower cyclone cones 410 are arranged inside the filter net 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. Part of the dust and air flow reaching the inner side 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. The larger particle dust reaching the inner side of the filter net 200 will be located lower under the action of gravity. Since the upper cyclone cones 310 are located above the lower cyclone cones 410, the larger particle dust located lower will mainly flow into the lower cyclone cones 410 for cyclone separation, and the smaller particle dust located higher will mainly flow into the upper cyclone cones 310 for cyclone 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, by setting the radial dimension of the upper cyclone cones 310 to be smaller than that of the lower cyclone cones 410, it is possible to 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 dust of different sizes on the basis of the primary separation, achieving a better separation effect.

[0106] 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 cones 410.

[0107] Specifically, the air guiding mechanism 500 is located inside the filter net 200. The bottom end of each air 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. The lower cyclone cone 410 has a lower cyclone chamber 411, and 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 air 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 air guiding pipe 510, thereby realizing cyclone separation. The separated clean air flow is discharged upward through the air guiding pipe 510, and the dust is deposited downward. The HEPA 800 is located above the air guiding pipe 510, and the clean air flow discharged upward from the top end of the air guiding pipe 510 will flow into the HEPA 800 for filtration. In the embodiment shown in the attached drawings, there are 6 lower cyclone cones 410. Therefore, at the corresponding positions, a total of 6 air guiding pipes 510 are provided that match them.

[0108] Refer to Figure 9 , in some embodiments, a plurality of air guiding pipes 510 are connected together by an integrally formed manner. Specifically, the air guiding mechanism 500 includes an intermediate plate 520, and a plurality of air guiding pipes 510 are all connected to the intermediate plate 520.

[0109] Refer to Figure 4 、 Figure 8 and Figure 9 , in some embodiments, among the air 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.

[0110] Specifically, the air 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 inserting the clamping block 4131 into the clamping groove 531, the connection and fixation between the air guiding mechanism 500 and the lower cyclone cone mechanism 400 can be realized.

[0111] Refer to Figure 3 、 Figure 4 、 Figure 6 、 Figure 8 And Figure 9 , in some embodiments, the air guiding pipe 510 includes a lower air guiding part 512 inserted into the lower cyclone cone 410 and an upper air guiding part 511 passing through the upper cyclone cone mechanism 300. The upper air guiding part 511 and the upper cyclone cone 310 are staggered in position. The lower air guiding part 512 and the upper air guiding part 511 are communicated, and the central axes of the two do not coincide.

[0112] Specifically, the lower air guide part 512 is connected to the bottom end of the upper air guide part 511, and the two are internally connected to allow air flow 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 respective hollow holes 340 are staggered from the positions of the upper cyclone cones 310. Each of the hollow holes 340 is respectively used for the respective upper air guide parts 511 to pass upward through. Referring also to Figure 10 , the lower air guide part 512 passes through the middle plate 520, that is, the bottom end part in the lower air guide part 512 extends downward from the middle plate 520, and the top end part extends upward from the middle plate 520. The top end part in the lower air guide part 512 is connected to the upper air guide part 511. Both the lower air guide part 512 and the upper air guide part 511 are columnar tubes, and the central axes thereof 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 that 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.

[0113] In the above embodiment, by setting the central axes of the lower air guide part 512 and the upper air guide part 511 to not coincide, the gap inside the filter net 200 other than the upper cyclone cone mechanism 300 and the lower cyclone cone mechanism 400 can be just occupied to set the air guide pipe 510, without increasing the space inside the filter net 200 for setting the air guide pipe 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.

[0114] Referring to Figure 2 , Figure 3 , Figure 4 and Figure 12 , in some embodiments, the cyclone separator includes an exhaust mechanism 600 for being arranged 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 to discharge the clean air flow separated by the upper cyclone cone 310, and each lower exhaust pipe 620 is inserted into a corresponding air guide pipe 510.

[0115] 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 end 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 tangentially 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 top ends of the upper exhaust pipe 610 and the lower exhaust pipe 620 can pass through the base plate 630 and enter the HEPA 800.

[0116] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 11 , in some embodiments, the cyclone separator includes a cyclone cover 700. The cyclone cover 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.

[0117] 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 the two. 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.

[0118] 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.

[0119] Specifically, one end of the lower cyclone cone 410 facing away from the corresponding air duct 510 is inclined towards the side close to 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.

[0120] 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°.

[0121] 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.

[0122] 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. The inner wall will be inclined and can match the inclined outer surface shape of the lower cyclone cone 410 to better accommodate 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 and keep them stably 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 be used to remove the hair wound around the outer wall of the protrusion 721 through the concave region.

[0123] 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 positions of 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.

[0124] Specifically, the dust discharge holes 420 penetrate the lower cyclone cone mechanism 400 up and down 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, so as to realize dust collection.

[0125] 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 towards the side close to the central axis of the cyclone separator.

[0126] Specifically, one end of the upper cyclone cone 310 close to the lower cyclone cone mechanism 400 is inclined towards the side close to the inner cylinder 710. 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 discharge holes 420 at the gaps between the lower cyclone cones 410, thereby making more effective use of space and making the structure more compact.

[0127] 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°.

[0128] 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 communicating with the inner cylinder 710 and a wind guiding channel 330 communicating 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 towards 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.

[0129] Specifically, the inner cylinder 710 is located at the center of the entire cyclone separator. The airflow and dust mixture flows upwards 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 on the intermediate 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 outer side 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, and a notch 210 is provided on the filter net 200. 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.

[0130] 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, so as to guide 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.

[0131] Refer to Figure 3 , Figure 4 , Figure 6 and Figure 7 , in some embodiments, the upper cyclone 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.

[0132] 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.

[0133] 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.

[0134] 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.

[0135] 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.

[0136] 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 cover 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 base plate 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.

[0137] Refer to Figures 1 to 3 , the cyclone separator is disposed below the Hepa 800. The air flow and dust mixture flow into the mixture inlet 711 from the air inlet pipe 120, and successively enter 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 by the filter screen 200. The large-sized dust is deposited in the primary dust collection chamber 110, and the 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.
