[0057] The working surface of the present invention can be a plane or a curved surface, can be inclined, or can be horizontal. For the convenience of description, the embodiment of the present invention is placed on a horizontal surface and used on the horizontal surface, and "high and low" and "up and down" are defined in this way.

[0058] Example 1

[0059] This embodiment provides a flow guide filter assembly, such as Figures 1 to 6 Shown, including:

[0060] A fluid conduit 1 for introducing fluid into the flow guide and filter assembly, which is provided with a fluid inlet 101 and a fluid outlet 102;

[0061] The filter part 2 is used to filter the fluid entering the diversion filter assembly;

[0062] The flow guide part 3 has one end connected to the fluid outlet 102 and the other end facing the filter part 2 so as to guide the fluid in the fluid pipeline 1 to the filter part 2 .

[0063] Compared with the prior art, the guide filter assembly of the present invention quickly guides the dust-laden fluid to the filter part 2 by providing the guide part 3, thereby avoiding the formation of turbulence in the dust collecting cup, which affects the filtering effect and filtering speed of the filter part.

[0064] The filter portion 2 is located outside the fluid conduit 1 and constitutes a part of the side wall of the flow guide filter assembly.

[0065] At least a portion of the fluid conduit 1 is enclosed within the side wall of the diversion filter assembly, and a gap is reserved between the side wall of the fluid conduit 1 and the side wall of the diversion filter assembly to allow the fluid filtered by the filter unit 2 to flow through the gap.

[0066] The fluid outlet 102 is provided on the side wall of the flow guide filter assembly. In this embodiment, the fluid outlet 102 is located above the filter portion 2 .

[0067] The guide part 3 is located on the outer side surface of the side wall of the guide filter assembly (the side away from the central axis of the guide filter assembly). Specifically, the guide part 3 spirally extends from the fluid outlet 102 to the filter part 2 to guide the fluid cyclone in the fluid pipeline 1 to the filter part 2. On the one hand, the guide part 3 guides the fluid entering the guide filter assembly so that the fluid is quickly guided to the filter part 2; on the other hand, the guide part 3 causes the fluid to form a cyclone outside the guide filter assembly, so that larger dust particles in the fluid are separated under the action of centrifugation, thereby reducing the filtering pressure of the filter part 2 and enabling the filter part 2 to have a better filtering effect.

[0068] In order to ensure the filtering effect of the filter part 2, the guide part 3 is located above the filter part 2, so that the entire filter part 2 can filter the fluid as much as possible and give full play to the filtering effect of the filter part 2.

[0069] Specifically, the guide part 3 includes a transverse plate 31 and a spiral plate 32. The transverse plate 31 is located above the fluid outlet 102. The spiral plate 32 is connected to the transverse plate 31, and the spiral direction of the spiral plate 32 is toward the filter part 2 to guide the fluid spiral to the filter part 2 for filtering and dust removal.

[0070] In this embodiment, the spiral plate 32 includes a connecting end and an extending end. The connecting end is connected to the transverse plate 31 . The connecting end spirally extends downward to the extending end. The extending end is located below the fluid outlet 102 and above the filter portion 2 .

[0071] It should be noted that the transverse plate 31 and the spiral plate 32 are vertically connected to the side wall of the flow guide filter assembly to guide the fluid to the filter part 2 faster and better.

[0072] The downward projection of the transverse plate 31 can completely cover the fluid outlet 102, that is, the length of the transverse plate 31 is greater than the length of the fluid outlet 102 (the length of the fluid outlet 102 refers to the longest distance between the left and right ends of the fluid outlet 102), so as to ensure that the fluid discharged from the fluid outlet 102 can be guided through the transverse plate 31. In addition, it can also prevent the guide part 3 from blocking the fluid outlet 102 and affecting the speed of the fluid being discharged outward.

[0073] In this embodiment, the horizontal plate 31 is disposed along the upper edge of the fluid outlet 102, and the lower end surface of the horizontal plate 31 is flush with the upper end surface of the fluid outlet 102 to ensure smooth fluid discharge from the fluid outlet 102. The extended end of the spiral plate 32 is connected to the lower edge of the fluid outlet 102; specifically, the lower end surface of the extended end is flush with the lower end surface of the fluid outlet 102.

[0074] In order to better guide the fluid flowing out of the fluid outlet 102 along the guide portion 3 to the filter portion 2, the guide portion 3 further includes a baffle 33, which is located at the end where the fluid outlet 102 is connected to the extended end of the spiral plate 32. The baffle 33 is also connected to the cross plate 31, the spiral plate 32, and the side wall of the guide filter assembly. Specifically, the upper end of the baffle 33 is perpendicularly connected to the lower end surface of the cross plate 31, the lower end of the baffle 33 is perpendicularly connected to the upper end surface of the spiral plate 32, and the inner end surface of the baffle 33 is perpendicularly connected to the end of the fluid outlet 102 near the extended end of the spiral plate 32. This ensures that after the fluid is discharged from the fluid outlet 102, it can only be guided to the filter portion 2 along the cross plate 31 and the spiral plate 32, thereby accelerating the speed at which the fluid is guided to the filter portion 2, thereby improving the filtration speed of the filter portion 2, and at the same time preventing the fluid from being diverted in the opposite direction from the other end, causing turbulence in the fluid and affecting the filtration effect and filtration speed of the guide filter assembly.

[0075] To guide the fluid to the filter portion 2 as quickly as possible, the helical angle α of the flow guide portion 3 is less than 360°. To ensure that the fluid forms a cyclone in the flow guide portion 3, 180° ≤ α, and therefore 180° ≤ α < 360°. In this embodiment, α refers to the helical angle between the connecting end and the extending end of the spiral plate 32.

[0076] To ensure that the fluid is better guided at the guide part 3 and a cyclone is formed, the fluid pipeline 1 includes a direct current pipe 11 and a cyclone pipe 12. A fluid inlet 101 is provided at one end of the direct current pipe 11, and the other end of the direct current pipe 11 is sealed and connected to the cyclone pipe 12, so that all the fluid entering the direct current pipe 11 is introduced into the cyclone pipe 12.

[0077] The cyclone tube 12 includes a central portion 121 and an arcuate portion 122. The bottom of the central portion 121 is connected to the direct current tube 11. The sidewall of the central portion 121 is provided with an opening. One end of the arcuate portion 122 is connected to the central portion 121 through the opening. The other end of the arcuate portion 122 is provided with a fluid outlet 102. Specifically, one end of the arcuate portion 122 is connected to the central portion 121, and the other end is connected to the sidewall of the diversion filter assembly. The arcuate portion 122 has an opening at the connection with the central portion 121, and a fluid outlet 102 is provided at the connection with the diversion filter assembly. In this embodiment, the opening on the sidewall of the central portion 121 extends from the top end to the bottom end of the sidewall.

[0078] An arc-shaped channel is provided in the arc-shaped portion 122 to guide the fluid therethrough to form a cyclone, so that the fluid can be better guided along the guide portion 3 after being discharged to the fluid outlet 102 .

[0079] It should be noted that the arc of the arc portion 122 faces the guide portion 3, that is, the arc direction of the arc channel of the arc portion 122 is consistent with the spiral direction of the spiral plate 32, so that the fluid can be guided from the guide portion 3 to the filter portion 2 more quickly, and at the same time make it easier for the fluid to form a cyclone.

[0080] Furthermore, the side wall of the central portion 121 transitions in an arc shape to the outer side wall of the arc portion 122 (the side wall away from the central axis of the central portion 121), and the inner side wall of the arc portion 122 (the side wall close to the central axis of the central portion 121) transitions in an arc shape to the side wall of the diversion filter assembly, so that the opening of the fluid outlet 102 is as large as possible so that the fluid can be guided to the guide portion 3 more quickly. In addition, the two arc transitions make the fluid guidance smoother and easier to form a cyclone.

[0081] It should be noted that the bottom wall of the arcuate portion 122 is sealedly connected to the side walls of the central portion 121, and the inner and outer side walls of the arcuate portion 122 are respectively sealedly connected to the side walls of the central portion 121, to ensure that the fluid in the central portion 121 can fully enter the arcuate channel of the arcuate portion 122. In this embodiment, the lower end surface of the bottom wall of the arcuate portion 122 is flush with the bottom end surface of the side walls of the central portion 121, and the opening extends from the top to the bottom of the side walls of the central portion 121, to ensure that the fluid in the central portion 121 can quickly and smoothly enter the arcuate portion 122.

[0082] After the dust-laden fluid enters the diversion and filtering assembly from the fluid inlet 101, it is guided by the direct current pipe 11, the central portion 121 and the arc-shaped portion 122 of the cyclone pipe 12, and then cyclones out of the fluid outlet 102 to the guide portion 3. After being guided by the horizontal plate 31 and the spiral plate 32 of the guide portion 3, it is cycloned into the filter portion 2 for filtration.

[0083] In this embodiment, the direct current pipe 11 is a cylindrical pipe with its upper end located inside the side wall of the diversion and filtration assembly and its lower end located below the side wall of the diversion and filtration assembly. A fluid inlet 101 is provided at the lower end of the direct current pipe 11. The upper end of the direct current pipe 11 is sealedly connected to the central portion 121 of the cyclone pipe 12. The central axis of the direct current pipe 11 is collinear with the central axis of the diversion and filtration assembly.

[0084] In this embodiment, the cyclone tube 12 is enclosed within the sidewalls of the diversion and filtration assembly. The central portion 121 of the cyclone tube 12 is cylindrical, with the same diameter as the direct current tube 11. The sidewalls of the two are flush, and the central axis of the central portion 121 is collinear with the central axis of the diversion and filtration assembly. The outer wall of the curved portion 122 transitions in an arcuate pattern with the sidewall of the central portion 121, while the inner wall of the curved portion 122 transitions in an arcuate pattern with the sidewall of the diversion and filtration assembly.

[0085] The bottom plate 4 of the diversion and filtering assembly is covered at the bottom end of the side wall of the diversion and filtering assembly, and a through hole for the fluid pipe 1 to pass through is opened in the center of the bottom plate 4. Specifically, the bottom plate 4 is detachably and sealedly connected to the side wall of the diversion and filtering assembly, and the bottom plate 4 is sealedly connected to the side wall of the fluid conduit 1.

[0086] In this embodiment, the direct current tube 11 passes through the through hole of the bottom plate 4 and is connected to the cyclone tube 12. The side wall of the direct current tube 11 is sealed with the bottom plate 4. A portion of the direct current tube 11 is located above the bottom plate 4, and a portion is located below the bottom plate 4. The fluid inlet 101 is located below the bottom plate 4.

[0087] In this embodiment, the bottom end of the filter part 2 is detachably sealed to the bottom plate 4, and the filter part 2 constitutes the lower side wall of the diversion filter assembly. The fluid filtered by the filter part 2 enters the gap between the side wall of the diversion filter assembly and the fluid pipeline 1.

[0088] The cover plate 5 of the diversion filter assembly is positioned over the top of the fluid conduit 1, ensuring that all fluid entering the fluid conduit 1 is discharged through the fluid outlet 102 on the side wall of the diversion filter assembly. The shape of the cover plate 5 matches the top of the fluid conduit 1 to ensure that the top of the fluid conduit 1 is sealed. A gap is reserved between the cover plate 5 and the side wall of the diversion filter assembly. This gap communicates with the gap between the side wall of the diversion filter assembly and the fluid conduit 1, allowing filtered fluid to exit the diversion filter assembly through the gap between the cover plate 5 and the side wall of the diversion filter assembly.

[0089] In this embodiment, the shape of the cover plate 5 is adapted to the top shape of the cyclone tube 12 , and a sealing cover is provided on the top of the central portion 121 and the arc portion 122 to ensure that all fluid entering the fluid pipeline 1 is guided to the filter portion 2 through the fluid outlet 102 .

[0090] In order to ensure that the filtered dust is no longer directed to the filter part 2, a dust shield 21 is provided at the bottom end of the filter part 2. The dust shield 21 is arranged around the bottom end of the filter part 2, and the shape of the dust shield 21 is trumpet-shaped, extending outward and downward from the top end of the dust shield 21 to the bottom end to prevent the filtered dust from being directed to the filter part 2 again.

[0091] To create an independent dust storage space after the diversion filter assembly is installed in the dust cup, a partition 6 is provided at the top of the diversion filter assembly's sidewall. The partition 6 surrounds the outside of the diversion filter assembly's sidewall and is located above the diversion portion 3. When the diversion filter assembly is installed in the dust cup, the fluid inlet 101 of the fluid conduit is sealed and connected to the dust suction port of the integrated cup. The partition 6 is in sealing contact with the sidewall of the dust cup, forming an independent dust storage space between the dust cup bottom, the dust cup sidewall, the sidewall of the diversion filter assembly, the sidewall of the fluid conduit 1, and the partition 6. Dust filtered by the filter portion 2 is located within this dust storage space.

[0092] In this embodiment, the partition 6 is shaped like a trumpet, extending outward and upward from the bottom end of the partition 6 to the top end, guiding the filtered fluid when it is discharged from the diversion filter assembly, so that the fluid can be discharged from the top gap of the diversion filter assembly as soon as possible.

[0093] In order to make the fluid conduit 1 more stable in the side wall of the diversion filter assembly, a plurality of ribs 7 are provided between the side wall of the fluid conduit 1 and the side wall of the diversion filter assembly. In this embodiment, the ribs 7 are located between the side wall of the center portion 121 of the cyclone tube 12 and the side wall of the diversion filter assembly.

[0094] In this embodiment, the side wall of the diversion filter assembly except the filter portion 2 is called the upper side wall portion, the diversion portion 3 is located in the upper side wall portion, the fluid outlet 102 is opened in the upper side wall portion, the rib plate 7 is located between the upper side wall portion and the side wall of the center portion 121 of the cyclone tube 12, and the length of the center portion 12 is the same as the length of the upper side wall portion. In order to facilitate processing and assembly and the stability of the diversion filter assembly, the upper side wall portion, the diversion portion 3, the cyclone tube 12, the rib plate 7, the cover plate 5, and the partition plate 6 are integrally formed.

[0095] In this embodiment, the top of the filter portion 2 is sealed to the bottom of the upper side wall, and the bottom of the filter portion 2 is detachably sealed to the bottom plate 4. Specifically, the filter portion 2 is a filter screen, the top of the filter screen is sealed to the bottom of the upper side wall, and the bottom of the filter screen is detachably sealed to the bottom plate.

[0096] Example 2

[0097] This embodiment provides a dust collection device, such as Figures 7 to 12 As shown, it includes the diversion filter assembly provided in Example 1.

[0098] Compared with the prior art, the dust collection device provided in this embodiment has the beneficial effects of the diversion filter assembly provided in the first embodiment, which will not be described in detail here.

[0099] The above-mentioned dust collection equipment also includes a cone filter assembly 8, which is located downstream of the diversion filter assembly, that is, the fluid filtered by the diversion filter assembly is directed to the cone filter assembly 8 for further filtration, and the cone filter assembly 8 is located above the diversion filter assembly.

[0100] At this time, the diversion filter assembly also includes a dust collecting ring wall 9, which is located between the fluid pipeline 1 and the side wall of the diversion filter assembly, that is, the dust collecting ring wall 9 is arranged on the outside of the direct current tube 11 and the center part 121, and the side wall of the diversion filter assembly is arranged on the outside of the dust collecting ring wall 9, and there is a gap between the dust collecting ring wall 9 and the fluid pipeline 1 and the side wall of the diversion filter assembly.

[0101] The bottom end of the dust collecting ring wall 9 is detachably sealed to the bottom plate 4 , and the top end of the dust collecting ring wall 9 is flush with the cover plate 5 .

[0102] In this embodiment, some ribs 7 are located between the dust collecting ring wall 9 and the side wall of the cyclone tube 12, and some ribs 7 pass through the dust collecting ring wall 9 and are located between the cyclone tube 12 and the upper side wall. The ribs 7 passing through the dust collecting ring wall 9 are sealed and connected to the dust collecting ring wall 9.

[0103] It should be noted that the dust collecting ring wall 9 is provided with a slot for the arcuate portion 122 of the cyclone tube 12 and the cover plate 5 to pass through, and the integrated ring wall 9 is sealedly connected to the side wall and bottom wall of the arcuate portion 122.

[0104] Thus, a central dust-collecting space is formed between the bottom plate 4, the dust-collecting annular wall 9, and the sidewalls of the fluid conduit 1. Dust filtered by the cone filter assembly 8 is collected in this central dust-collecting space. Furthermore, a space for the fluid filtered by the filter unit 2 to circulate (this space is referred to as the circulation space) is formed between the bottom plate 4, the dust-collecting annular wall 9, and the sidewalls of the diversion filter assembly. That is, the fluid that has passed through the first stage of filtration by the filter unit 2 enters the circulation space and is then discharged from the top of the diversion filter assembly.

[0105] The conical filter assembly 8 includes a motor assembly chamber 81 and multiple cyclone cones 82. The cyclone cones 82 are positioned outside the motor assembly chamber 81. By locating the motor assembly chamber 81 within the conical filter assembly 8, the length of the vacuum cleaner can be effectively reduced, improving the user experience. Furthermore, the cyclone cones 82 positioned outside the motor assembly chamber 81 effectively reduce the noise and vibration generated by the high-speed rotation of the motor assembly, achieving excellent noise and vibration reduction effects.

[0106] The dust-laden fluid entering the cyclone cone 82 may form a cyclone therein, and impurities such as dust in the dust-laden fluid may be separated and filtered out under the action of centrifugal force and gravity.

[0107] The cyclone cone 82 is provided with an air inlet 801, an air outlet 802 and a dust guide port 803. The dust-laden fluid after the first-stage filtration enters the cyclone cone 82 through the air inlet 801. After the cyclone filtration of the cyclone cone 82, the filtered fluid is discharged out of the cyclone cone 82 through the air outlet 802, and the filtered dust is discharged out of the cyclone cone 828 through the dust guide port 803.

[0108] The air inlet 801 is opened on the side wall of the cyclone cone 82, the air outlet 802 is opened at the top of the cyclone cone 82, and the dust guide port 803 is located at the lowest point of the cyclone cone 82 to ensure that the filtered dust and other impurities can all be guided out of the cyclone cone 82 through the dust guide port 803.

[0109] In order to quickly guide the cyclone cone 82 to the central dust collecting space, the cone filter assembly 8 also includes a dust guide 83. The top end of the dust guide 83 is connected to the bottom end of the cyclone cone 82, and the bottom end of the dust guide 83 is connected to the top of the dust collecting ring wall 9, and the dust guide 83 is arranged around the outside of all dust guide ports 803.

[0110] Specifically, the dust guide member 83 is trumpet-shaped, extending downward and inward from the top end to the bottom end, that is, the opening of the dust guide member 83 faces the position where the motor assembly cavity 81 is located.

[0111] Because the air inlet 801 is opened on the side wall of the cyclone cone 82, a certain distance is maintained between adjacent cyclone cones 82, that is, the cyclone cones 82 are arranged alternately, that is, the cyclone cones 82 do not contact each other, so as to ensure smooth air intake through the air inlet 801.

[0112] A connecting plate 84 is provided between two adjacent cyclone cones 82 , and the connecting plate 84 extends from the top of the side wall of the cyclone cone 82 to the bottom of the side wall of the cyclone cone 82 , and all the air inlets 801 are located on the outside of the connecting plate 821 to prevent the setting of the connecting plate 84 from affecting the air intake of the air inlet 201 .

[0113] In this embodiment, the top end face of the connecting plate 84 is flush with the top end face of the cyclone cone 82, the bottom end face of the connecting plate 84 is flush with the bottom end face of the cyclone cone 82, the two side end faces of the connecting plate 84 are respectively connected to the side walls of adjacent different cyclone cones 82, and the outer wall surface of the connecting plate 84 is flush with the inner end face of the air inlet 801.

[0114] In this way, the connecting plate 84, the two adjacent cyclone cones 82 and the outer wall of the motor assembly cavity 81 enclose a cavity, which is called a partition cavity. The outer side of the motor assembly cavity 81 is completely wrapped by the partition cavity and the cyclone cone 82, which can effectively reduce the vibration and noise generated when the motor in the motor assembly cavity 81 is working, and produce good vibration reduction and noise reduction effects.

[0115] It should be noted that the bottom end of the connecting plate 84 is connected to the top end of the dust guide 83 to prevent dust from leaking out.

[0116] The cone filter assembly 8 further comprises a cover 85 , which is provided on the top of the side wall of the cone filter assembly, that is, the cover 85 is provided on the top of the cyclone cone, the motor assembly cavity and the connecting plate.

[0117] Specifically, the cover body 85 is provided with an air guide area, an air inlet area and an air outlet area. The air outlet area is surrounded on the outside of the air inlet area, and the air guide area is surrounded on the outside of the air outlet area. The air guide area corresponds to the cyclone cone and the connecting plate, and the air inlet area and the air outlet area correspond to the motor assembly cavity 81. The air guide area is used to guide the fluid filtered by the cyclone cone, and the air inlet area and the air outlet area are used to pass the fluid in and out of the motor assembly cavity 81.

[0118] The air guide area is provided with air guide ports 804 to guide the fluid filtered by the cyclone cones 82 out of the conical filter assembly. In this embodiment, the number of air guide ports 804 matches the number of cyclone cones 82, and there is a one-to-one correspondence between each air guide port 804 and the cyclone cones 82. The air guide ports 804 are connected to the air outlet 802, allowing the filtered fluid to be guided out of the conical filter assembly through the air guide ports 804.

[0119] The air inlet area is provided with an air inlet 805 communicating with the motor assembly cavity 81 , and the fluid enters the motor assembly cavity 81 through the air inlet 805 .

[0120] The air outlet area is provided with an air outlet 806 communicating with the motor assembly cavity 81 , and the fluid in the motor assembly cavity 81 is discharged out of the motor assembly cavity 81 through the air outlet 806 . A plurality of air outlets 806 are provided, and these air outlets 806 are arranged outside the air inlet 805 .

[0121] In this embodiment, the air inlet area is located at the center of the cover body 85 , and the air inlet 805 is located at the center of the cover body 85 .

[0122] In order to make the cyclone cone 82 have a better filtering effect and speed up the discharge of the filtered fluid, the cover body 85 is provided with an air guide tube 851. One end of the air guide tube 851 is connected to the air guide port 804, and the other end extends from the air guide port 804 into the cyclone cone 82. The port inside the cyclone cone 82 is located below the air inlet 801 to prevent the fluid from being directly discharged from the cyclone cone 82 without being filtered by the cyclone.

[0123] To better guide the fluid into a cyclone within cyclone cone 82, a guide portion 821 is provided at air inlet 801. Guided by guide portion 821, the fluid enters cyclone cone 82 tangentially to the sidewalls of the cyclone cone. Specifically, guide portion 821 includes an air inlet passage that extends through air inlet 801. This air inlet passage is tangential to the sidewalls of the cyclone cone, guiding the fluid and allowing it to more quickly and easily form a cyclone within the cyclone chamber, thereby enhancing the filtration efficiency of cyclone cone 82.

[0124] The dust collection device further comprises a dust collecting cup, and the guide filter assembly and the cone filter assembly are detachably installed in the dust collecting cup.

[0125] A dust suction port is provided at the bottom of the dust collecting cup, the bottom end of the fluid pipe 1 is in sealing contact with the bottom of the dust collecting cup, and the fluid inlet 101 is connected to the dust suction port, so that the dust-containing fluid entering the dust collecting cup from the dust suction port is all introduced into the diversion filter assembly through the fluid inlet 101.

[0126] The partition 6 is in sealing contact with the side wall of the dust cup, and the cover 85 is in sealing contact with the side wall of the dust cup, so that the guide filter assembly and the cone filter assembly divide the dust removal space into a closed space without interfering with each other, so that the dust collection equipment has a better dust removal effect.
