Detailed ways

The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

1 to 5 show an embodiment of a dust cup provided by the present invention.

The dust cup includes an upper dust cup 2 and a lower dust cup 3 connected as one. The upper dust cup 2 and the lower dust cup 3 are coaxial cylindrical structures. A cyclone separator 5 is arranged inside the dust cup 2 at the upper end, and an air inlet 10 communicating with the air inlet pipe 1 is provided on its side wall.

The dust cup adopts the design of small top and big bottom, that is, the volume of the upper dust cup 2 is smaller than that of the lower dust cup 3, and the diameter of the upper dust cup 2 is smaller than the lower dust cup 3. A radially extending connecting plate 11 is provided on the outer periphery of the upper dust cup 2 near the end of the upper dust cup 2 . The side of the connection plate 11 facing the lower dust cup 3 is provided with a hook 12 facing the lower dust cup 3 . The outer peripheral surface of the dust cup 3 at the lower end is provided with a slot 13 which snap fits with the hook 12 . The lower dust cup 3 and the upper dust cup 2 are detachably connected through the buckle structure 4 formed by the hook 12 and the groove 13 .

The dust cup 3 at the lower end forms a storage chamber for accommodating the dirt separated by the cyclone separator 5 . An isolation structure 6 is provided in the storage chamber, and the isolation structure 6 divides the storage chamber into a first chamber 7 on the same side as the cyclone separator 5 and a second chamber 8 isolated from the cyclone separator 5 . The isolation structure 6 is a hemispherical bowl-shaped structure with an opening 9 facing the cyclone separator 5 , and an opening 9 is provided at the bottom to allow fine dirt to pass through. The upper end of the inner wall of the lower end dust cup 3 is provided with a certain height concave spherical restriction card platform 14, which cooperates with the spherical contour of the isolation structure 6 to realize the function of restricting and fixing the bowl-shaped structure.

The bottom of the bowl-shaped structure has a hole and the size of the hole is appropriate. Smaller-diameter dust and dirt enter the second chamber 8 through the opening 9, and larger-diameter dirt stays on the isolation structure 6 and falls into the second chamber 8. Because the isolation structure 6 is isolated from the cyclone separator 5, the dust is avoided, and the quality and volume of the dirt received by the isolation structure 6 are relatively large, so it will not be affected by the cyclone to generate dust. Such a design can prevent the collected dirt from generating dust under the drive of the cyclone separator 5, which is beneficial to improve the cleaning effect such as dust removal rate, and also avoids the damage of dust to the dust cup, separator, filter screen and other parts of the vacuum cleaner. The above-mentioned vacuum cleaner The service life of the components is significantly increased.

From the above description, it can be seen that the dirt with a larger diameter is stored in the first chamber 7, and the dirt with a smaller diameter such as fine dust is stored in the second chamber 8. The setting of the isolation structure 6 can also classify garbage with different diameters. , easy to collect.

The dust cup provided by the present invention adopts a design with a small top and a large bottom, which has the following advantages: first, the dust cup 3 at the lower end is larger, which increases the space for the dust cup to accommodate dirt; secondly, the dust cup 3 at the lower end is larger, and the collected dirt It can avoid to a greater extent from being affected by the cyclone air and dust from the upper cyclone separator 5 to generate dust; again, the upper part is small and the lower part is large, the center of gravity is better, and the hand is more stable.

As another implementation manner, the detachable connection of the upper dust cup 2 and the lower dust cup 3 is realized through other detachable connection structures. For example, the end of the upper dust cup 2 is provided with a connecting sleeve sleeved on the top of the lower dust cup 3, the inner wall of the connecting sleeve is provided with a threaded structure, and the lower dust cup 3 is correspondingly provided with a threaded structure, the upper dust cup 2 and the lower dust cup 3 The detachable connection is realized by thread structure.

As another embodiment, when the isolation structure 6 is used to prevent dust, other structures can also be used, which can isolate the cyclone separator 5 and open an opening 9 to allow dirt to pass through. For example, referring to Fig. 6 and Fig. 7, the lower dust cup 3 is embedded with a conical guide plate 15 with an opening 9 facing the second chamber 8; Gaps16. The conical guide plate 15 guides the dirt down into the second chamber 8 by means of the conical surface. When the vacuum cleaner continues to work, the conical guide mechanism blocks the contact of the cyclone dirt and the dirt already received to prevent dust.

As another embodiment, a plurality of isolation structures 6 can be arranged in the dust cup 3 at the lower end, and the upper opening 9 of the isolation structures 6 becomes smaller along the direction away from the cyclone separator 5, so as to realize the purpose of finer garbage classification.

As another embodiment, multiple detachable dust cups can be set, that is, the bottom end of the lower dust cup 3 can also be detachably connected with auxiliary dust cups, and several are arranged in sequence to facilitate the classification of dirt and increase the capacity of the dust cups.

The dust cup provided by the present application is also effective for the air intake pipe 1 from the bottom of the dust cup. Specifically, as shown in FIG. 8 and FIG. 9 , the dust cup includes an upper dust cup 2 and a lower dust cup 3 connected as one. The upper dust cup 2 and the lower dust cup 3 are coaxial cylindrical structures. The dust cup 2 at the upper end is provided with a cyclone separator 5 . The axis of the air inlet pipe 1 coincides with the axis of the dust cup and the cyclone separator 5, and one end of the air inlet pipe 1 enters from the bottom of the dust cup 3 at the lower end, extends to the inside of the cyclone separator 5, and connects to the top baffle 17 of the cyclone separator 5, The other end is located outside the dust cup. Correspondingly, the isolation structure 6 is provided with a through hole structure allowing the air inlet pipe 1 to pass through. One end of the air inlet pipe 1 corresponding to the cyclone separator 5 is provided with an air outlet, and communicates with the inside of the dust cup 2 at the upper end through the channel structure 18 provided on the cyclone separator 5 . Air dust enters from the air inlet pipe 1, reaches the interior of the upper dust cup 2 through the air outlet and the channel structure 18, and is separated by a cyclone. The space between the walls of the cyclone separator 5 is discharged.

The present invention also provides a dust collection device using the above dust cup.

Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or changes derived therefrom are still within the scope of protection of the present invention.
