At the same time, the dust cup end cap d7 is connected to the stop of the dust cup body d1 through the first end cap mating portion d702, which improves the connection strength of the dust cup end cap d7 and further improves the stability of the dust cup wire bracket d6.

[0061] On the basis of the above embodiment, as a further limited embodiment, Figure 2 As shown, the dust cup wire bracket d6 includes: an inner ring limiting wall d603; an outer ring limiting wall d604, disposed around the inner ring limiting wall d603, with a storage space formed between the outer ring limiting wall d604 and the inner ring limiting wall d603; and a bracket partition d605, disposed within the storage space, with the wiring groove d601 formed between the bracket partition d605 and the outer ring limiting wall d604. The wiring groove d601 is located outside the bracket partition d605, i.e., on the side close to the inner wall of the dust cup, to facilitate the extension of the dust cup wire d5 to the outside of the dust cup body d1.

[0062] On the basis of the above embodiment, as a further limited embodiment, Figure 4 、 Figure 5 As shown, a bracket assembly groove d606 is formed between the bracket partition d605 and the inner ring limiting wall d603, and the bracket assembly groove d606 opens toward the second end cover matching portion d703.

[0063] The dust and dirt separation device of this embodiment further includes: a first bracket sealing ring d608, which is arranged in the bracket assembly groove d606, and the first bracket sealing ring d608 is supported between the bracket assembly groove d606 and the second end cover matching portion d703. Since the dust cup wire bracket d6 is clamped between the second end cover matching portion d703 and the inner wall of the dust cup, the second end cover matching portion d703 is close to the inner ring limiting wall d603 of the dust cup wire bracket d6. In this solution, the first bracket sealing ring d608 is assembled between the inner ring limiting wall d603 and the second end cover matching portion d703 to eliminate the installation gap of the dust cup wire bracket d6 and further improve the installation strength and stability of the dust cup wire bracket d6.

[0064] On the basis of the above embodiment, as a further limited embodiment, Figure 2 、 Figure 5 As shown, a second bracket sealing ring d609 is provided between the dust cup wire bracket d6 and the inner wall of the dust collecting chamber. The second bracket sealing ring d609 is supported between the dust cup wire bracket d6 and the inner wall of the dust collecting chamber, further eliminating the installation gap of the dust cup wire bracket d6 and further improving the installation strength and stability of the dust cup wire bracket d6.

[0065] On the basis of the above embodiment, as a further limited embodiment, Figure 2 、 Figure 5 As shown, the dust cup wire bracket d6 is provided with an outer ring limiting groove d612 suitable for accommodating the second bracket sealing ring d609 on the side facing the inner wall of the dust collecting chamber.

[0066] On the basis of the above embodiment, as a further limited embodiment, Figure 1 、 Figure 2 、 Figure 4 As shown, it also includes: a bracket assembly screw d111, which passes through the dust cup body d1, the dust cup wire bracket d6, and the dust cup end cover d7 for fastening. The dust cup body d1 is provided with a bracket assembly hole d110 suitable for passing the bracket assembly screw d111, and the dust cup end cover d7 is provided with an end cover assembly hole d704 adapted for the bracket assembly screw d111. The bracket assembly screw d111 passes through the dust cup body d1, the wire bracket, and the dust cup end cover d7 from the outside of the dust cup body d1, further improving the structural strength and structural stability of the three-part assembly. Specifically, the wire bracket has a clearance area for the bracket assembly screw d111 to pass through.

[0067] On the basis of the above embodiment, as a further limited embodiment, Figure 2As shown, the dust cup wire bracket d6 has a first mounting buckle d602 on the surface facing the dust collection chamber, and a first mounting slot d109 is provided on the inner wall of the dust collection chamber, which is compatible with the first mounting buckle d602. During installation, the second bracket sealing ring d609 is inserted into the outer ring limiting groove d612, and then the dust cup wire bracket d6 is installed on the inner wall of the dust collection chamber near the dust cup stop d108 through the first mounting buckle d602 and the first mounting slot d109.

[0068] Further, such as Figure 2 、 Figure 4 As shown, the second end cover fitting portion d703 is provided with a second mounting buckle d701 on the side facing the dust cup wire bracket d6, and the dust cup wire bracket d6 is provided with a second mounting slot d607 adapted to the second mounting buckle d701. Before installing the dust cup end cover d7, the first bracket sealing ring d608 is installed in the bracket assembly slot d606, and then the end cover is assembled on the dust cup wire bracket d6 through the second mounting buckle d701 and the second mounting slot d607. Specifically, in this embodiment, the dust cup end cover d7 is first assembled with the dust cup wire bracket d6, and then the assembled dust cup wire bracket d6 is uniformly assembled to the dust cup stop d108. As an alternative embodiment, the dust cup wire bracket d6 can also be assembled on the dust cup stop d108 first, and then the dust cup end cover d7 is uniformly assembled.

[0069] On the basis of the above embodiment, as a further limited embodiment, Figure 2 As shown, outer ring reinforcement ribs d6041 are provided on the side of the outer ring limiting wall d604 facing the bracket partition d605, and / or on the side of the bracket partition d605 facing the outer ring limiting wall d604. The outer ring reinforcement ribs d6041 not only enhance the strength of the outer ring limiting wall d604 and the outer bracket partition d605, but also are formed within the wiring trough d601 to further limit the dust cup wire d5 disposed therein, thereby improving the assembly efficiency of the dust cup wire d5.

[0070] On the basis of the above embodiment, as a further limited embodiment, Figure 2 、 Figure 5As shown, the dust cup wire bracket d6 includes: a stop limit portion d611, which extends to above the open end of the dust cup body d1, and the stop limit portion d611 is set to abut against the open end of the dust cup body d1. The stop limit portion d611 extends to above the open end of the dust cup body d1. Specifically, the stop limit portion d611 extends above the dust cup stop d108. When the dust cup wire bracket d6 is assembled on the dust cup stop d108, the dust cup wire bracket d6 can be assembled to the preset position through the limiting effect of the stop limit portion d611, thereby improving the assembly efficiency. Specifically, as Figure 2 、 Figure 5 As shown, the stop limit portion d611 is located above the clearance area, and the left and right sides of the clearance area are third wiring notch portions d113 suitable for installing the dust cup wiring plug d503.

[0071] Furthermore, when the dust separation device of this embodiment is applied to a vacuum cleaner, Figure 7 - Figure 8 As shown, compared to the vacuum cleaner as a whole, the dust separation device is equivalent to the dust cup component d. Figure 1 、 Figure 7 The opening at the top of the dust cup body d1 is assembled with the main body shell of the vacuum cleaner, and in this embodiment, the dust cup body d1 is assembled below the main body shell of the vacuum cleaner.

[0072] On the basis of the above embodiment, as a further limited embodiment, combined with Figure 7 、 Figure 11 、 Figure 12 The main body shell includes a main body bottom shell a105, which has an annular portion. The opening of the dust cup body d1 is correspondingly assembled on the annular portion of the main body bottom shell a105. The main body bottom shell a105 also has a bottom shell extension portion a106 extending into the dust collecting chamber d4. Figure 9 、 Figure 10 As shown, the bottom shell extension a106 is bent relative to the main body bottom shell a105 into the annular space surrounded by the main body bottom shell a105. Figure 10 From the perspective, the cross-sectional area of ​​the main body bottom shell a105 gradually decreases from top to bottom, and the bottom shell extension a106 continues to extend into the dust collecting chamber d4, so that an assembly space is formed between the bottom shell extension a106 and the inner wall of the dust cup body d1. As an alternative embodiment, Figure 10 From the perspective, the bottom shell extension a106 extends into the dust collecting chamber d4 in the vertical direction and extends downwards to the bottom of the dust collecting chamber d4. At this time, the bottom shell extension a106 can be set in contact with the inner wall of the dust collecting chamber d4, and the end cover lip d705 and the sealing extension d6081 are both sandwiched between the bottom shell extension a106 and the inner wall of the dust collecting chamber d4 to form a seal. The dust cup body d1 moves relative to the main body bottom shell a105 during assembly, and the dust cup body d1 moves relative to the main body bottom shell a105 during assembly. Figure 8、 Figure 10 , taking the dust cup body d1 as a reference, the main unit bottom shell a105 undergoes an assembly movement from top to bottom relative to the dust cup body d1 to be inserted into the dust cup body d1.

[0073] On the basis of the above embodiment, as a further limited embodiment, Figure 7 、 Figure 9 As shown, a dust cup end cover d7 is provided on the opening at the top of the dust cup body d1. Figure 8 、 Figure 10 The dust cup end cover d7 has an annular groove adapted to the top open end of the dust cup body d1, so that the dust cup end cover d7 fits the inner and outer sides of the open end of the dust cup body d1.

[0074] Specifically, such as Figure 8 、 Figure 10 As shown, the thickness of the dust cup end cover d7 located on the inner side of the dust cup body d1 is greater.

[0075] Furthermore, the portion of the dust cup end cover d7 located inside the dust collecting chamber d4 has an end cover extension portion d707 extending toward the dust collecting chamber d4. Figure 8 As shown, the end cover extension d707 is arranged obliquely. As an alternative embodiment, the end cover extension d707 is arranged in a vertical direction.

[0076] On the basis of the above embodiment, as a further limited embodiment, the dust cup wire bracket d6 is provided on the dust cup body d1, as shown in FIG. Figure 10 As shown, the left top end of the dust cup wire bracket d6 extends to the open end surface of the dust cup body d1, and is clamped between the dust cup end cover d7 and the open end surface of the dust cup body d1 to achieve fixation.

[0077] Specifically, such as Figure 10 As shown, a first bracket seal ring d608 is sandwiched between the right side of the dust cup wire bracket d6 and the end cover extension d707 of the dust cup end cover d7. The first bracket seal ring d608 extends toward the bottom shell extension a106. A sealing extension d6081 is provided on the side of the first bracket seal ring d608 near the bottom shell extension a106. The sealing extension d6081 bends toward the bottom shell extension a106.

[0078] Further, such as Figure 10 As shown, the bottom of the bottom shell extension a106 is provided with a bottom shell bent portion a1061, which bends toward the inner wall of the dust cup body d1, so that the bottom shell bent portion a1061 and the sealing extension d6081, on the basis of the original contact, further contact is formed to form a seal. The inner wall of the dust cup body d1, that is, the inner wall of the dust collecting chamber d4 surrounded by the dust cup body d1.

[0079] Specifically, such as Figure 10 、 Figure 11 As shown, when the dust cup body d1 is assembled on the main unit bottom shell a105, the main unit bottom shell a105 moves from top to bottom relative to the dust cup body d1, the bottom shell bent portion a1061 is inserted into the dust collecting chamber d4, and the sealing extension portion d6081 extends to the assembly path where the bottom shell bent portion a1061 moves downward, causing the bottom shell bent portion a1061 to contact the sealing extension portion d6081 during the assembly process and push the sealing extension portion d6081 to further undergo elastic deformation.

[0080] Furthermore, the sealing extension d6081 and the first bracket sealing ring d608 form an obtuse angle on the side facing the bottom shell extension a106. When the sealing extension d6081 is pushed and deformed by the bottom shell bent portion a1061, the angle formed by the sealing extension d6081 and the first bracket sealing ring d608 on the side facing the bottom shell extension a106 increases. The first bracket sealing ring d608 is made of an elastic material, in this embodiment, hard rubber. This angled shape provides a certain degree of elasticity, further improving the sealing performance between the sealing extension d6081 and the bottom shell bent portion a1061.

[0081] On the basis of the above embodiment, as a further limited embodiment, Figure 8 、 Figure 10 As shown, the dust cup end cover d7 extends a step surface into the dust collecting chamber d4, and an end cover lip d705 is provided on the step surface. The end cover lip d705 is clamped between the bottom shell extension a106 and the dust cup end cover d7. The end cover lip d705 forms a further seal above the first bracket sealing ring d608. The first bracket sealing ring d608 and the end cover lip d705 form a double-layer sealing structure in the height direction.

[0082] Furthermore, the end cover lip d705 is made of soft rubber material, and the end cover lip d705 is injection molded on the dust cup end cover d7. Figure 8 、 Figure 10 As shown, a mating engagement portion d7051 is provided between the end cap lip d705 and the dust cup end cap d7. In this embodiment, the mating portion d7051 comprises a mating groove and a protrusion. This increases the contact area between the end cap lip d705 and the dust cup end cap d7, enhancing the bonding strength. As an alternative, the mating portion d7051 can also be a zigzag interlocking joint.

[0083] The sealing principle of the end cover lip d705 is as follows: Figure 10As shown, when the dust cup body d1 is assembled on the main unit bottom shell a105, the main unit bottom shell a105 is pressed downward and contacts the end cover lip d705 to form a seal. Furthermore, the main unit bottom shell a105 has an inclined bottom shell extension a106, which causes the end cover lip d705 to tilt toward the inside of the dust cup end cover d7 during the compression deformation process and further fit the inclined bottom shell extension a106, further improving the sealing performance of the end cover lip d705.

[0084] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
