[0029] The following will be described in detail with reference to the accompanying drawings. Figures 1-6 The present application will be described in further detail.

[0030] The present application discloses a dust collecting device. Figure 1 and Figure 2The dust collection device includes a cyclone body 1, which is installed in the dust cup of the vacuum cleaner for separating air and dust. The cyclone body 1 has a cyclone channel 2, with a suction pipe 3 at one end. One end of the suction pipe 3 is connected to one end of the cyclone channel 2, and the other end is connected to the vacuum cleaner's suction port. The cyclone channel 2 changes the direction of airflow, making the airflow spiral. This spiral airflow improves the efficiency of dust-air separation through centrifugal force and inertia. A guide plate 4 is snapped onto the other end of the cyclone body 1 at the cyclone channel 2. The guide plate 4, together with the cyclone body 1, forms the cyclone channel 2. The guide plate 4 and the cyclone body 1 are detachably connected for separate injection molding.

[0031] Reference Figure 3 The guide plate 4 has an inner mounting protrusion 41, and the cyclone body 1 has a mounting groove 11 located at the outlet of the cyclone channel 2 on the cyclone body 1. The mounting protrusion 41 is inserted into the mounting groove 11 to fix the guide plate 4 and the cyclone body 1. After the guide plate 4 is inserted along the mounting groove 11, the inner wall of the guide plate 4 connects with the inner wall of the cyclone body 1 to form the cyclone channel 2. Specifically, the mounting groove 11 is set along the movement trajectory of the airflow in the cyclone channel 2, and the mounting groove 11 is arc-shaped and opened on the circumferential side wall of the cyclone body 1.

[0032] Reference Figure 3 and Figure 4 One end of the guide plate 4 is provided with a buckle 42, and the cyclone body 1 is provided with a slot 12. The buckle 42 is engaged with the slot 12 to further fix the guide plate 4 and the cyclone body 1. Specifically, multiple buckles 42 are provided, with one end of the multiple buckles 42 linearly arranged on the guide plate 4. The slot 12 is formed along the direction of the linear arrangement of the buckles 42, and multiple buckles 42 are engaged with one slot 12. Further, the buckle 42 has a snap-fit ​​protrusion 421, and the snap-fit ​​protrusions 421 of adjacent buckles 42 are located on different sides of the buckle 42. (See attached diagram) Figure 2 When the buckle 42 is engaged in the slot 12, the buckle 42 deforms under the pressure of the slot wall. When the buckle 42 passes through the slot 12, the elastic force of the buckle 42 to return to its original shape causes the engaging protrusions 421 to abut against the slot walls on both sides of the slot 12. The engaging protrusions 421 are restricted and difficult to dislodge from the slot 12. The engaging protrusions 421 on both sides of the buckle 42 can prevent the buckle 42 from sliding off the slot wall on one side of the slot 12. The engaging protrusions 421 have guide surfaces 422, which are inclined in the insertion direction of the buckle 42 to guide the buckle 42 through the slot 12.

[0033] Reference Figure 3 and Figure 5The guide plate 4 includes a base plate 43 and a side plate 44, which are integrally formed. A mounting protrusion 41 is located on one side of the base plate 43. The base plate 43 is connected to the bottom surface of the cyclone body 1 at the outlet of the cyclone channel 2. The side plate 44 is connected to the inner wall of the cyclone body 1 at the outlet of the cyclone channel 2. A buckle 42 is located on the side plate 44. The side plate 44 includes an inner arc plate 441, an outer arc plate 442, and a side bottom plate 443. An inclined plate 444 is connected between the inner arc plate 441 and the outer arc plate 442. The inclined plate 444, the inner arc plate 441, the outer arc plate 442, and the side bottom plate 443 form a cavity. When installing the guide plate 4, insert the mounting protrusion 41 along one end of the mounting groove 11. When the mounting protrusion 41 slides to the other end of the mounting groove 11, the buckle 42 passes through the slot 12 so that the locking protrusion 421 abuts against the groove walls on both sides of the slot 12. At this time, the inner arc plate 441 is connected to the side wall of the cyclone channel 2, and the outer arc plate 442 is connected to the outer side wall of the cyclone body 1, so that the guide plate 4 and the cyclone body 1 are relatively fixed to form the cyclone channel 2.

[0034] Reference Figure 1 The cyclone body 1 has a guide slope 13 on the opposite side of the guide plate 4. The guide slope 13 is located on the side wall at the outlet of the cyclone channel 2. The guide slope 13 is inclined towards the central axis of the rotating body to expand the flow radius of the airflow and guide the airflow from the cyclone channel 2 to flow towards the side wall of the dust cup of the vacuum cleaner, so that the airflow spirals along the side wall of the dust cup of the vacuum cleaner.

[0035] Reference Figure 2 and Figure 6 The suction pipe 3 and the cyclone body 1 are connected as one unit. The cyclone channel 2 includes a straight section and a spiral section. The straight section of the cyclone channel 2 is connected to the suction pipe 3. The spiral section of the cyclone channel 2 is used to change the direction of the airflow, so that the airflow flows in a spiral shape.

[0036] The cyclone body 1 has an air outlet 14 at the end furthest from the suction duct 3. The air outlet 14 is isolated from the cyclone channel 2 and is used to discharge the air after dust separation. The cyclone body 1 is also provided with filter holes 15, which can filter large dust particles and also serve as ventilation holes. After dust-air separation, the remaining air enters the air outlet 14 through the filter holes 15 and is discharged from the air outlet 14.

[0037] The implementation principle of a dust collection device according to an embodiment of this application is as follows: the mounting protrusion 41 is inserted into the mounting groove 11, the buckle 42 passes through the groove 12, and the engaging protrusion 421 abuts against the groove walls on both sides of the groove 12, so that the guide plate 4 is relatively fixed on the cyclone body 1. The inner arc plate 441 and the cyclone body 1 form a cyclone channel 2. When the gas drawn in from the suction pipe 3 changes direction after passing through the cyclone channel 2, it flows out from the air duct between the guide plate 4 and the guide slope 13. The guide slope 13 guides the airflow of the cyclone channel 2 to flow towards the side wall of the dust cup of the vacuum cleaner. Under the action of centrifugal force and inertia, dust adheres to the dust cup, and the gas is discharged from the air outlet 14.

[0038] This application also discloses a vacuum cleaner, which includes a dust cup and a cyclone body 1. The cyclone body 1 is installed in the dust cup of the vacuum cleaner for separating air and dust. A guide plate 4 is snapped onto the cyclone body 1. The guide plate 4 is used to form a cyclone channel 2 together with the cyclone body 1. The guide plate 4 and the cyclone body 1 are detachably connected to each other for separate injection molding.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
