[0026] In addition, the meaning of the term "plurality" should be two or more.

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] As Figures 1 to 3 shown, a vacuum cleaner with a function of preventing forgetting to install a filter screen includes a main body assembly 1, a filter screen assembly 2, and a dust cup 3. The main body assembly 1 is fixedly connected to the dust cup 3 through the filter screen assembly 2. The filter screen assembly 2 includes a filter screen body 201 and a docking ring 202. The filter screen body 201 is fixedly arranged on the inner wall of the docking ring 202. The dust cup 3 has a first bayonet 4 fixedly connected to one end of the docking ring 202. The main body assembly 1 has a second bayonet 5 fixedly connected to the other end of the docking ring 202. Both ends of the docking ring 202 are respectively inserted into the inner cavities of the first bayonet 4 and the second bayonet 5. A first limiting assembly is provided between the docking ring 202 and the inner wall of the first bayonet 4. A second limiting assembly is provided between the docking ring 202 and the second bayonet 5.

[0029] Specifically, during use, the main body assembly 1 cannot be directly docked and installed with the dust cup 3. Instead, the filter screen assembly 2 is used as a connecting member between the main body assembly 1 and the dust cup 3. During installation, one end of the filter screen assembly 2 is docked with the first bayonet 4, and the other end is docked with the second bayonet 5, and it is fixed by the first limiting assembly and the second limiting assembly to prevent the filter screen or the dust cup 3 from falling off during use. In this embodiment, by using the filter screen as the connecting member between the main body assembly 1 and the dust cup 3, and the main body assembly 1 cannot be docked with the dust cup 3, this vacuum cleaner cannot be used when forgetting to install the filter screen, thereby effectively reminding the user and avoiding the situation that dust enters the main body and causes damage to the main body due to forgetting to install the filter screen.

[0030] The docking ring 202 includes a first docking portion 2021, a second docking portion 2022, and a hand-held portion 2023. The hand-held portion 2023 is fixedly arranged between the first docking portion 2021 and the second docking portion 2022. The outer diameter of the hand-held portion 2023 is greater than the outer diameters of the first docking portion 2021 and the second docking portion 2022. The outer diameter of the first docking portion 2021 is equal to the inner diameter of the first bayonet 4. The outer diameter of the second docking portion 2022 is equal to the inner diameter of the second bayonet 5.

[0031] Specifically, the outer diameter of the handheld part 2023 is larger than that of the first docking part 2021 and the second docking part 2022, which is convenient for the user to hold the filter screen for disassembly and assembly. Here, the outer diameter of the handheld part 2023 can be set to be equal to the outer diameter of the dust cup 3, so as to make the appearance of the vacuum cleaner regular and beautiful. It should be noted that the materials of the docking ring 202, the first docking port, and the second docking port can be plastic or rubber, so that their connection parts have a damping feeling and prevent the parts from falling off after assembly.

[0032] The first limiting component includes a first limiting protrusion 6 and a first limiting groove 7 that cooperate with each other. The first limiting protrusion 6 is fixedly arranged on the outer wall of the first docking part 2021, and the first limiting groove 7 is opened on the inner wall of the first bayonet 4.

[0033] Specifically, when connecting the filter screen assembly 2 and the dust cup 3, after the first limiting groove 7 and the first limiting protrusion 6 are aligned, the filter screen assembly 2 and the dust cup 3 are inserted. Here, the first limiting groove 7 can be an L-shaped groove, and the first limiting protrusion 6 can be an L-shaped protrusion. After installation, the cooperation of the L-shaped groove and the L-shaped protrusion can limit the circumferential direction of the two to a certain extent and can also perform axial limitation, making their connection more stable. When installing, after inserting the L-shaped protrusion into the L-shaped groove, rotating the filter screen can realize the axial limitation of the two.

[0034] The second limiting component includes a second limiting protrusion 8 and a second limiting groove 9 that cooperate with each other. The second limiting protrusion 8 is fixedly arranged on the inner wall of the second bayonet 5, and the second limiting groove 9 is opened on the outer wall of the second docking part 2022.

[0035] Specifically, the second limiting component can adopt a cooperation method similar to that of the first limiting component. Here, only the second limiting groove 9 is opened on the second docking part 2022, so that the first docking part 2021 has a limiting protrusion and the second docking part 2022 has a limiting protrusion, which is convenient for the user to distinguish the orientation of the filter screen during installation and improves the installation efficiency.

[0036] The outer diameter of the first docking part 2021 is not equal to the outer diameter of the second docking part 2022. Specifically, the unequal outer diameters make it impossible to install the filter screen if the orientation is incorrect, preventing the user from installing the filter screen backwards.

[0037] The inner wall of the dust cup 3 is also provided with an abutting part 301. The end of the abutting part 301 abuts against the end of the first docking part 2021, and the inner diameter of the abutting part 301 is equal to the inner diameter of the first docking part 2021. Specifically, the equal inner diameter of the abutting part 301 and the first docking part 2021 makes the inside of the connection between the dust cup 3 and the filter screen assembly 2 smooth and reduces the jamming of dust.

[0038] An ornamental seal 10 is fixedly arranged on the outside of the second bayonet 5, and the end of the ornamental seal 10 abuts against the end of the handheld part 2023. The cross-section of the ornamental seal 10 is frustum-shaped, and the diameter of the ornamental seal 10 near one end of the dust cup 3 is smaller than that of the other end. Specifically, since components such as motors and fans need to be installed inside the main body assembly 1, the diameter of its housing is usually large. The ornamental seal 10 is used for the transition between the main body assembly 1 and the dust cup 3 to make the vacuum cleaner more beautiful. At the same time, the ornamental seal 10 can be made of rubber material and has elasticity, so that there is pressure between the ornamental seal 10 and the end of the handheld part 2023, thereby making the connection at the second limiting assembly more stable.

[0039] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
