Fig. 1 is a schematic diagram of the structure of a vacuum cleaner according to an exemplary embodiment, and Fig. 2 is an exploded diagram of the structure of a vacuum cleaner according to an exemplary embodiment. As shown in Figs. 1 and 2, the vacuum cleaner 100 may include a vacuum cleaner housing 1, a dust separation structure 2 capable of separating air and dust, a motor 3, a post-motor filter structure 4, a dust cup 5, and a functional part 6. In which, the vacuum cleaner 100 may include a handheld vacuum cleaner, so that the functional part 6 may include a holding part 61 connected to the vacuum cleaner shell 1, and an assembly part 62 connected to the holding part 61 and the dust cup 5, and the extension direction of the holding part 61 is at a preset angle with the depth direction of the dust cup 5 to provide an operating space when the user holds the vacuum cleaner 100; the extension direction of the assembly part 62 is perpendicular to the depth direction of the dust cup 5, wherein, when the vacuum cleaner 100 may include a handheld vacuum cleaner, the handheld vacuum cleaner may include a battery module (not shown in the figure), which can be assembled in the assembly part 62, and can be electrically connected to the dust separation structure 2 and the motor 3 to provide power for the normal operation of the dust separation structure 2 and the motor 3.

Furthermore, the dust cup 5 and the vacuum cleaner housing 1 can be stacked substantially along the depth direction of the dust cup 5, and the dust cup 5 can be snapped onto the vacuum cleaner housing 1, and the dust separation structure 2 is located inside the dust cup 5 and snapped onto the end of the vacuum cleaner housing 1, so that the dust separated by the dust separation structure 2 can be stored inside the dust cup 5. The gas separated by the dust separation structure 2 can pass through the motor 3, and can be further filtered by the post-motor filter structure 4, and then discharged from the vacuum cleaner 100 to avoid secondary pollution to the indoor air.

In this embodiment, as shown in Figure 3, the dust separation structure 2 may include a clamping portion 21. When the dust separation structure 2 and the vacuum cleaner shell 1 are in a clamping state, the clamping portion 21 may contact the vacuum cleaner shell 1 to provide a clamping force acting on the vacuum cleaner shell 1, so that the vacuum cleaner shell 1 and the dust separation structure 2 are relatively fixed; when an external force acts on the vacuum cleaner shell 1 or the dust separation structure 2 and overcomes the clamping force, the dust separation structure 2 can be separated from the vacuum cleaner shell 1, which is convenient for the user to clean the dust separation structure 2, or when the separation ability of the dust separation structure 2 is poor or even no longer can play a dust separation role, it is convenient for the user to replace the dust separation structure to maintain a good dust suction effect of the vacuum cleaner 100.

Furthermore, the motor 3 may include a motor body 31 and a motor housing 32 surrounding the motor body 31, and the motor post-filter structure 4 may include a pre-filter body 41 and a mounting structure 42 for assembling the pre-filter body 41. The pre-filter body 41 may be detachably connected to the motor housing 32 via the mounting structure 42. In this way, it is not only convenient for the user to clean the motor post-filter structure 4, but also the motor body 31 may be covered by the motor post-filter structure to protect the motor body 31.

The connection between the dust separation structure 2 and the vacuum cleaner housing 1 is mainly achieved through the clamping connection between the dust separation structure 2 and the vacuum cleaner housing 1 and the clamping force of the clamping part 21 on the vacuum cleaner housing 1.

In one embodiment, as shown in Figures 4 and 5, the dust separation structure 2 may include a first groove 22 that is recessed in a direction away from the vacuum cleaner housing 1, and a snap-in groove 23 that is recessed inward by the inner wall of the first groove 22. The vacuum cleaner housing 1 may include a snap-in block 11 that can cooperate with the snap-in groove 23, thereby achieving snap-in connection between the dust separation structure 2 and the vacuum cleaner housing 1.

For example, still as shown in FIG. 5 , the clamping groove 23 may include an inserting portion 231 and a limiting portion 232 connected to the inserting portion 231, and the limiting portion 232 may include a limiting block 2321 arranged parallel to the bottom surface of the first groove 22; wherein the clamping block 11 may be inserted into the inserting portion 231 along the depth direction of the first groove 22, and may slide into the limiting portion 232 along the axial direction of the first groove 22, and the clamping block 11 is limited by the limiting block 2321 in the depth direction of the first groove 22. wherein the inserting portion 231 may include a guide surface, and the guide surface may be used to guide the clamping block 11 when it is inserted into the inserting portion 231, so as to reduce the difficulty of assembly; similarly, the limiting block 2321 may also include a guide surface to guide the clamping block 11 when it moves toward the limiting portion 232.

In this embodiment, when the clamping block 11 is slid into the limiting portion 232, the clamping block 11 can still slide toward the plug-in portion 231 along the axial direction of the first groove 22. Therefore, contact between the clamping portion 21 and the vacuum cleaner housing 1 is required to prevent the clamping block 11 from moving toward the insertion portion 231.

Specifically, still as shown in Figure 4, the dust separation structure 2 can also include a second groove 24 formed by the inner wall of the first groove 22 being recessed inwardly, and the clamping portion 21 can be rotatably connected to the second groove via a rotating shaft; when the vacuum cleaner housing 1 or the dust separation structure 2 rotates along the axial direction of the first groove 22, a force can be applied to the clamping portion 21 to cause it to rotate along the rotating shaft and be pressed into the second groove 24. The clamping portion 21 pressed into the second groove 24 can maintain contact with the vacuum cleaner housing 1 to provide a clamping force that keeps the dust separation structure 2 and the vacuum cleaner housing 1 relatively fixed.

In one embodiment, the clamping portion 21 may include a clamping body 211 and an elastic member 212. The clamping body 211 can be rotatably connected to the second groove 24 via a rotating shaft. The elastic member 212 can be passed through the rotating shaft, and one end of the elastic member 212 abuts against the inner wall of the second groove 24, and the other end abuts against the surface of the clamping body 211 facing the second groove 24. Therefore, in the process of the clamping body 21 being pressed into the second groove 24, the elastic member 212 is deformed, thereby being able to provide a clamping force to the vacuum cleaner housing 1 while maintaining the tendency of the clamping body 211 to separate from the second groove 24.

In another embodiment, the clamping portion 21 can be made of an elastic material, and when the vacuum cleaner shell 1 and the dust separation structure 2 are in a separated state, the clamping portion 211 is located in the second groove 24, and there is a portion protruding from the inner wall of the first groove 22, so that when the first groove 22 moves circumferentially between the vacuum cleaner shell 1 or the dust separation structure 2, the portion protruding from the inner wall of the first groove 22 is pressed into the second groove 24, and the clamping portion 21 is deformed, thereby providing a clamping force.

For each of the above embodiments, as shown in FIG6 , the dust separation structure 2 may further include a dust separation body 25 and a pre-filter body 26. The airflow separated by the dust separation body 25 may be filtered by the pre-filter body 25 before entering the motor 3, thereby preventing particles and powder from entering the motor 3 and causing damage to the motor 3. The first groove 22 is located on the dust separation body 25, and the pre-filter body 26 may be snapped into the first groove 22. The pre-filter body 26 may include a filter 261 and a mounting portion 262 for mounting the filter 261. The mounting portion 262 may cooperate with the dust separation body 25 to limit the pre-filter body 25.

The dust separation body 25 may include a cyclone separator to separate dust from airflow by utilizing the centrifugal force generated by the cyclone separator, and the separated dust may be stored in the dust cup 5, and the airflow may be sucked into the motor 3 after being filtered by the pre-filter body 26, and further filtered by the post-motor filter structure 4. In particular, the cyclone separator may include a secondary cyclone separator to improve the separation effect between dust and airflow.

In one embodiment, the shape of the mounting portion 262 may match the shape of the first groove 22 , and the mounting portion 262 and the first groove 22 may be tightly matched to achieve position limiting of the pre-filter body 25 .

In another embodiment, still as shown in Figure 6, the dust separation body 25 may include a third groove 251 formed by the inward depression of the vertical wall surrounding the first groove 22, and the mounting portion 262 may include a mounting protrusion 2621 that cooperates with the third groove 251, so that the pre-filter body 26 is limited by the cooperation between the mounting protrusion 2621 and the third groove 251.

In another embodiment, when there is a contact portion between the surface of the pre-filter body 26 and the pressing portion 21 , the pre-filter body 26 can also be restricted inside the first groove 22 by the force provided by the pressing portion 21 .

It should be noted that: when a part of the pre-filter body 26 and the vacuum cleaner housing 1 are in contact with the pressing part 21, the pressing part 21 is pressed into the second groove 24 by the first-assembled part, and the later-assembled part can be assembled to the dust separation body 25 after overcoming the pressing force provided by the pressing part 21. For example, when the vacuum cleaner housing 1 is assembled first, the vacuum cleaner housing 1 can press the pressing part 21 into the second groove 24; when the pre-filter body 26 is assembled first, the pre-filter body 26 can press the pressing part 21 into the second groove 24. Although the pressing part 21 will no longer rotate relative to the second groove 24 when the vacuum cleaner housing 1 is assembled later, it should be understood that the vacuum cleaner housing 1 still has the ability to make the pressing part 21 rotate relative to the second groove 24.

Other embodiments of the present disclosure will be readily apparent to those skilled in the art after considering the specification and practicing the disclosure disclosed herein. This application is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art that are not disclosed in the present disclosure.

It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
