Referring to fig. 1 and 2 together, the present application provides a cleaning apparatus including a housing and a separating assembly 100. The shell has and accepts the chamber, has seted up air intake and air outlet on the shell, and air intake and air outlet all communicate in outside and accept between the chamber. The separating assembly 100 is accommodated in the accommodating cavity, and includes a dust collecting member 20, a separating member 10, a filter member 30, an air guide member 40, and a fan (not shown). The separating member 10 has a dust discharging section and a separating section which are oppositely arranged and connected with each other, the dust collecting member 20 is sleeved outside one end of the dust discharging section far away from the separating section and is communicated with the dust discharging section, and the air guide member 40 is partially sleeved in the dust discharging section and is connected and communicated with the dust discharging section. The filter member 30 is disposed outside the separating member 10 and abuts between the dust collecting member 20 and the air guiding member 40. The fan is arranged on the side of the wind guide 40 facing away from the separating element 10.

Cleaning device during operation, the fan starts, and outside air current flows to outside through the air intake in proper order, accept the chamber, filter piece 30, separator 10, air guide 40, fan, air outlet. The filter element 30 is adapted to filter the airflow passing therethrough and separate the airflow into a primary airflow and a solid dirt separation of large particles. The solid dirt with large particles is collected in the accommodating cavity, and the primary air flow flows into the separation section of the separator 10 under the action of the fan. And then, the primary air flow is subjected to cyclone separation in the separation section and one end of the dust exhaust section connected with the separation section, and secondary air flow and small-particle solid dirt are formed. Then, the small solid dirt particles are collected in the dust collecting member 20 under the guiding of the dust discharging section, and the secondary air flows out from the air outlet under the guiding of the air guiding member 40. Therefore, the cleaning equipment can perform gas-solid separation on the external air flow and collect the separated solid dirt, so that the external environment can be improved, and the requirement of a user can be met by the external environment.

The separating part 10 comprises a base 11 and a plurality of cyclone separating bodies 13, all the cyclone separating bodies 13 are connected to the base 11 and penetrate through the base 11 along the central axis direction of the base 11, and all the cyclone separating bodies 13 are continuously distributed around the central axis of the base 11. Preferably, the base 11 is integrally formed with all of the cyclone bodies 13, so as to improve the difficulty of assembling the separator 10, and also to provide excellent sealing between each cyclone body 13 and the base 11.

Referring to fig. 3, 4 and 5, each cyclone body 13 has a hollow cylindrical separating portion 131, wherein the number a of the cyclone bodies 13 satisfies the condition: 3 pieces A and 5 pieces A, and the inner diameter D of each separation part 131₁The conditions are satisfied: d is not more than 19 mm₁Less than or equal to 25 mm. In particular, the separation portions 131 of all the cyclone bodies 13 combine to form a separation section of the separator 10. An air inlet 1312 is opened on the sidewall of each separating portion 131, and a separating channel 1314 communicated with the air inlet 1312 is formed around the inner wall of each separating portion 131. The air guide member 40 includes an end plate 43 and a plurality of air guide pipes 41 coupled to the same side of the end plate 43, and an air guide channel 45 is formed by enclosing an inner wall of each air guide pipe 41. All the air guide pipes 41 correspond to all the cyclone separators 13 one by one, and each air guide pipe 41 extends into the separation channel 1314 of the separation part 131 of the corresponding cyclone separator 13 and is arranged at an interval with the separation part 131, so that each air guide channel 45 can be communicated with the corresponding separation channel 1314.

Wherein, each cyclone body 13 further comprises a dust exhaust part 133 connected with the separating part 131, the inner wall of each dust exhaust part 133 is surrounded to form a dust exhaust channel 1334, and the dust exhaust channel 1334 is communicated with the separating channel 1314. The dust collecting member 20 has a dust collecting chamber 21, and the dust discharging parts 133 of all the cyclone bodies 13 are combined to form a dust discharging section and extend into the dust collecting chamber 21, so that the dust discharging passage 1334 in each dust discharging part 133 can communicate with the dust collecting chamber 21.

When the cleaning apparatus is operated, the primary air flow flows into the separation passage 1314 inside thereof from the air inlet 1312 of each cyclone body 13, and is separated into a secondary air flow and small particles of solid dirt in the separation passage 1314 and the end of the dust exhaust passage 1334 communicating with the separation passage 1314 (the flow direction of the primary air flow is shown by arrow a → arrow b → arrow c → arrow d → arrow e → arrow f in fig. 1). Then, the small solid dirt particles are collected in the dust collecting chamber 21 under the guidance of the dust exhaust passage 1334, and the secondary air flow is guided by the air guide passage 45 and left to the outside (the flow direction of the secondary air flow is shown by arrow g → arrow h → arrow j → arrow k → arrow m → arrow n → arrow t in fig. 1).

In the conventional cleaning apparatus, a single cyclone body 13 is provided on the base 11. The airflow flowing from the outside is separated into cyclones in the cyclone body 13. In order to ensure that the cleaning device has a larger air inlet amount and air outlet amount, the diameter of the cyclone separating body 13 is larger. Thus, the demand for a miniaturized cleaning apparatus cannot be satisfied, and the separation effect is poor.

In the present application, the plurality of cyclone bodies 13 are continuously arranged around the central axis of the base 11, so that the arrangement of all the cyclone bodies 13 can be compact, and the size of the separator 10 can be reduced adaptively. Further, the number a of the cyclone bodies 13 satisfies the condition: a is more than or equal to 3 and less than or equal to 5, and compared with the traditional separating piece 10 with a single cyclone separating body 13, the primary airflow can be divided into the cyclone separating bodies 13 and respectively subjected to cyclone separation, so that the separating piece also has a better separating effect. Further, the inner diameter D of each separation part 131₁The conditions are satisfied: d is not more than 19 mm₁Less than or equal to 25 mm, so that the size of the separating element 10 formed after a compact arrangement of all cyclone bodies 13 meeting this condition can be further reduced. Therefore, the separating element 10, the separating assembly 100 and the cleaning device provided in the present application have a small volume, so that the requirements of a miniaturized cleaning device can be met, and a good separating effect is also provided.

It is worth mentioning that as the diameter of the separating portion 131 in each cyclone body 13 is reduced, the diameter of the base 11 is also reduced adaptively to meet the demand for miniaturization of the separator 10. Preferably, the point of each cyclone body 13 which is furthest from the central axis of the base 11 is located in the plane of the outer peripheral surface of the base 11 or substantially close to the plane of the outer peripheral surface of the base 11, then in this embodiment the diameter of the base 11 can be considered to be the maximum diameter of the separator 10 and can be considered to be the maximum outer diameter of the circle which is formed by the enclosure of all the cyclone bodies 13.

Preferably, the inner diameter D of each separation part 131₁The conditions are satisfied: d is less than or equal to 21 mm₁Less than or equal to 23 mm. Within this size range, the diameter reduction of the separating portion 131 is small, and the diameter reduction can be performedThe air output and the separation effect of the whole cleaning equipment are almost not influenced, and the volume of the separating piece 10 can be reduced. That is, the inner diameter D of each separation part 131₁The conditions are satisfied: d is less than or equal to 21 mm₁When the size is less than or equal to 23 mm, the separating piece 10 has better separating effect and separating efficiency and can realize miniaturization.

Referring to fig. 4 again, the two cyclone bodies 13 with the farthest distance are defined as a first cyclone body and a second cyclone body, respectively, the separation portion 131 of the first cyclone body 13 is a first separation portion, and the separation portion 131 of the second cyclone body is a second separation portion. Wherein, the farthest distance L between the first separation part and the second separation part satisfies the condition: l is more than or equal to 69 mm and less than or equal to 71 mm. In this condition, the maximum outer diameter of a circle formed by enclosing all the cyclone bodies 13 is small. Correspondingly, the diameter of the separating element 10 is also reduced in a flexible manner, so that a smaller volume is also possible while a better separating effect of the cleaning device is ensured. Preferably, the farthest distance L between the first separating portion and the second separating portion satisfies the condition: l is more than or equal to 69 mm and less than or equal to 70 mm.

In some embodiments, the width B of the intake 1312 in each separation portion 131 satisfies the condition: b is more than or equal to 0.29 mm and less than or equal to 0.31 mm. Specifically, the width of the intake port 1312 refers to the width of the intake port 1312 in the circumferential direction of the separation portion 131. It can be understood that, on the premise of ensuring that the separating portion 131 has a good separating effect, the width of the air inlet 1312 is reduced, the diameter of the separating portion 131 is also smaller, and correspondingly, the diameter of the separating element 10 is also smaller. Therefore, by setting the width B of the intake port 1312 in each separation portion 131 to satisfy the condition: b is more than or equal to 0.29 mm and less than or equal to 0.31 mm, and the volume of the separating piece 10 can be further reduced, thereby facilitating the miniaturization of the cleaning equipment.

In some embodiments, the diameter D of the dust exhaust port 1332 of the dust exhaust portion 133₂The conditions are satisfied: 0.55D₁≤D₂≤0.57D₁. Specifically, 0.55D₁Represents D₁0.55 times of that of, 0.57D₁Represents D₁0.57 times. The dust exhaust part 133 is a hollow taper structure, and the diameter of the dust exhaust passage 1334 is along the wind guide40 to the dust collecting member 20, and has a minimum diameter at the dust discharge port 1332. As can be appreciated, the dust exhaust port 1332 is an exhaust port of the dust exhaust passage 1334. The main function of the dust exhaust channel 1334 is to guide the separated small particles of solid dirt to be collected in the dust collecting chamber 21. If the diameter of the dust exhaust port 1332 of the dust exhaust passage 1334 is small, the dust exhaust passage 1334 is easily blocked by solid dirt, and the solid dirt cannot be exhausted out of the cyclone 13. If the diameter of the dust outlet 1332 of the dust exhaust passage 1334 is larger, the cyclone generated in each separation passage 1314 is likely to flow into the dust collection chamber 21 through the dust exhaust passage 1334, and the solid dirt in the dust collection chamber 21 is collected back into the separation passage 1314, resulting in poor separation effect and low separation efficiency of the cyclone separator 13. In the present application, the diameter D of the dust exhaust port 1332 of the dust exhaust unit 133 is set₂The conditions are satisfied: 0.55D₁≤D₂≤0.57D₁Therefore, while the small particles of solid dirt can be discharged out of the cyclone body 13, the solid dirt in the dust collecting chamber 21 can be prevented from being rewound into the separating channel 1314, so that the separating effect and the separating efficiency are better.

Referring to fig. 1 again, in some embodiments, the depth H of each air guiding tube 41 extending into the corresponding separating portion 131 satisfies the condition: 0.98D₁≤H≤1.02D₁. Specifically, 0.98D₁Represents D₁0.98 times of that of 1.02D₁Represents D₁1.02 times of the total weight of the powder. As the air duct 41 extends into the corresponding separation portion 131, the primary air flow flowing into the separation channel 1314 from the air inlet 1312 spirally flows around the outer wall of the air duct 41, and the air-solid separation is performed. Specifically, the input port of air guiding pipe 41 is located below air inlet 1312 of separating portion 131, and the depth H of each air guiding pipe 41 extending into separating portion 131 corresponding to it satisfies the condition: 0.98D₁≤H≤1.02D₁In this way, the primary air flow flowing into the separation channel 1314 from the air inlet 1312 can collide with the outer wall of the air guide pipe 41, and gas-solid separation can be achieved. In addition, it can be ensured that the primary air flow flowing into the separation channel 1314 can perform multiple actions with the outer wall of the air guide pipe 41The secondary collision is performed, and the flow is guided by the air guide channel 45 to flow out after having a larger steering angle, so that the separation effect of the separation channel 1314 can be further improved.

In some embodiments, diameter D of end plate 43 of air guide 40₃The conditions are satisfied: d is not less than 94 mm₃Less than or equal to 98 mm. Specifically, in the separation module 100, the diameter of the end plate 43 of the air guide 40 is the largest. The diameter of the end plate 43 is the diameter of the separator assembly 100. Diameter D of end plate 43 of air guide 40₃The conditions are satisfied: d is not less than 94 mm₃98 mm or less, the volume of the separating assembly 100 can be further reduced, thereby enabling miniaturization of the cleaning apparatus. Preferably, the diameter D of the end plate 43 of the wind guide 40₃The conditions are satisfied: d is not less than 94 mm₃Less than or equal to 96 mm.

It should be noted that, in order to prevent the primary air flow or the secondary air flow in each separation passage 1314 from overflowing from the gap between the end plates 43 into the dust collecting chamber 21, a sealing member 50 may be further provided, and the sealing member 50 is clamped between the surface of the end surface facing the separating member 10 and the end surface of each separating portion 131 facing the end plate 43 to seal the end plate 43 and the separating member 10.

In the separating element 10, the separating assembly 100 and the cleaning device, the plurality of cyclone separating bodies 13 are coupled to the base 11 and are continuously arranged around the central axis of the base 11, so that the arrangement of the cyclone separating bodies 13 is compact, and the size of the separating element 10 can be adaptively reduced. Further, since the number a of the cyclone bodies 13 satisfies the condition: a is more than or equal to 3 and less than or equal to 5, and compared with the traditional separating piece 10 with a single cyclone separating body 13, the airflow can be distributed in each cyclone separating body 13 for gas-solid separation, so that the separation effect is better. Further, the inner diameter D of each separation part 131₁The conditions are satisfied: d is not more than 19 mm₁Less than or equal to 25 mm, the size of the separating element 10 formed after the close packing of all the cyclone bodies 13 satisfying this condition can be further reduced. It can be seen that the separating member 10, the separating assembly 100 and the cleaning device provided in the present application have a small volume and have a good separating effect.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
