[0033] Vacuum cleaners can be divided into upright, horizontal and portable types according to their structures. Their working principle is to use an electric motor to drive the blades to rotate at high speed, generating a negative air pressure in a sealed housing to suck up dust debris. In the prior art, when the user normally drags or twists the suction pipe assembly of the vacuum cleaner in a straight line, the suction hose is likely to fall off, which not only fails to ensure that the user can complete the cleaning in time, but also reduces the user experience.

[0034] To solve the problem of the suction hose being easily detached and improve the user experience, please refer to Figure 1 、 Figure 2 and Figure 4 According to an embodiment of the first aspect of the present utility model, a suction pipe joint structure of a vacuum cleaner is provided. The suction pipe joint structure 1 of the vacuum cleaner includes a main body portion 1a for being installed on the recovery bucket 2 of the vacuum cleaner, a first connection portion 1b for connecting with the recovery bucket 2, and a second connection portion 1c for connecting with the suction port seat cover 4 of the vacuum cleaner. Among them, the main body portion 1a is in the shape of a hollow cylinder, and a through hole for facilitating the entry of dust debris into the recovery bucket 2 is provided in the middle; the first connection portion 1b is columnar, extends along a direction parallel to the central axis of the main body portion 1a, and a connection hole 13 for facilitating fixation on the recovery bucket 2 is provided in the middle; the second connection portion 1c is in the shape of a polygonal sheet and protrudes along a direction perpendicular to the length direction of the first connection portion 1b.

[0035] For the consideration of ensuring the stable connection between the vacuum cleaner suction pipe joint structure 1, the recycling bin 2 and the suction port cover 4, in some embodiments, the number of the first connection parts 1b and the second connection parts 1c can both be multiple. In this embodiment, the number of the first connection parts 1b is three, and the number of the second connection parts 1c is four. Among them, the three first connection parts 1b are located in the middle of the main body part 1a, and the four second connection parts 1c are located at one end of the main body part 1a close to the recycling bin 2, and they are all evenly arranged on the outer circumferential surface of the main body part 1a.

[0036] As Figure 1 shown, to ensure the stable and reliable connection between the vacuum cleaner suction pipe joint structure 1 and the main suction pipe 3 of the vacuum cleaner, in this embodiment, the vacuum cleaner suction pipe joint structure 1 further includes a limiting part 1d for limiting the main suction pipe 3 of the vacuum cleaner. The main body part 1a is provided with a guiding groove 11 and a clamping groove 12. Among them, the limiting part 1d is arranged between the guiding groove 11 and the clamping groove 12, and the guiding groove 11 is used for guiding the main suction pipe 3 of the vacuum cleaner to be screwed into the clamping groove 12.

[0037] Specifically, the limiting part 1d is in the shape of a rib and extends radially along the bottom of the groove at the intersection position between the guiding groove 11 and the clamping groove 12 along the main body part 1a. The guiding groove 11 is in an L shape and includes a first groove section and a second groove section. Among them, the first groove section extends along the direction parallel to the length direction of the main body part 1a, and the second groove section extends from the end of the first groove section along the direction perpendicular to the length direction of the main body part 1a. It should be noted that in order to reduce the user's force for screwing the main suction pipe 3 inserted into the guiding groove 11 into or out of the clamping groove 12, in this embodiment, the side of the limiting part 1d close to the guiding groove 11 is a bevel surface, and the other side close to the clamping groove 12 is an arc surface, which is beneficial to reducing the friction force between the main suction pipe 3 and the limiting part 1d.

[0038] After the main suction pipe 3 is screwed into the clamping groove 12, in order to prevent the main suction pipe 3 from coming off when being normally pulled or twisted linearly, in this embodiment, one side of the end of the guiding groove 11 is flush with one side of the clamping groove 12, that is, one side of the second groove section of the guiding groove 11 is flush with one side of the clamping groove 12, and the width of the clamping groove 12 is greater than the width of the guiding groove 11. In this way, when the main suction pipe 3 is normally pulled or twisted linearly during use, the main suction pipe 3 will be jointly abutted by the front side wall of the clamping groove 12 and the side wall of the limiting part 1d close to the clamping groove 12, which is beneficial to preventing the main suction pipe 3 from coming off from the clamping groove 12.

[0039] An embodiment of the second aspect of the present utility model provides a suction pipe assembly. Please refer to Figure 2, including the main suction pipe 3 of the vacuum cleaner, the suction port cover 4, and the vacuum cleaner suction pipe joint structure 1 as described in the above embodiments. The vacuum cleaner suction pipe joint structure 1 is detachably connected between the main suction pipe 3 and the suction port cover 4, so that the above suction pipe assembly has the characteristics of good connection firmness and not easy to disconnect.

[0040] Specifically, as Figure 3 shown, the main suction pipe 3 is in a hollow tubular shape, and one end has a protrusion 31 that is adapted to both the guiding groove 11 and the clamping groove 12 of the vacuum cleaner suction pipe joint structure 1. The protrusion 31 is provided on the outer circumferential surface of the main suction pipe 3. In some embodiments, the number of protrusions 31 can be multiple. In this embodiment, the number of protrusions 31 is two.

[0041] The suction port cover 4 is in a hemispherical shape, and a notch 41 for communicating with the recovery bucket 2 is provided on the side wall.

[0042] In this embodiment, the suction pipe assembly further includes a suction hose of the vacuum cleaner (not marked in the figure). The suction hose is connected and integrally formed with the main suction pipe 3, and is sequentially connected to the recovery bucket 2 through the main suction pipe 3, the vacuum cleaner suction pipe joint structure 1, and the suction port cover 4, which is beneficial to reducing the production cost of the vacuum cleaner and improving the production efficiency.

[0043] An embodiment of the third aspect of the present invention provides a vacuum cleaner. Please refer to Figure 4 , including a motor (not marked in the figure), a blade (not marked in the figure) drivingly connected to the motor, a recovery bucket 2, a top cover 5, and the suction pipe assembly as described in the above embodiments. Among them, the motor and the blade are housed between the top cover 5 and the recovery bucket 2. A through hole corresponding to the connection hole 13 of the vacuum cleaner suction pipe joint structure 1 is provided in the recovery bucket 2, so as to fix the vacuum cleaner suction pipe joint structure 1 on the recovery bucket 2 through a fixing member passing through the connection hole 13. When the vacuum cleaner performs the suction function, the blade rotates at a high speed under the drive of the motor to discharge the air in the vacuum cleaner, and a negative air pressure is generated in the recovery bucket 2, so that external dirt enters the recovery bucket 2 through the suction pipe assembly, making the above vacuum cleaner have the characteristic of better user experience.

[0045] The utility model discloses a suction pipe joint structure of a vacuum cleaner, which comprises a main body part for being installed on a recovery bucket of the vacuum cleaner, a first connecting part for connecting with the recovery bucket, a second connecting part for connecting with a suction port seat cover of the vacuum cleaner, and a limiting part for limiting the main suction pipe of the vacuum cleaner. Among them, the first connecting part extends along a direction parallel to the central axis of the main body part, and the second connecting part protrudes along a direction perpendicular to the length direction of the first connecting part; a guiding groove and a clamping groove communicated with the guiding groove are formed in the main body part. The guiding groove is used for guiding the main suction pipe to be screwed into the clamping groove, and the limiting part is arranged between the guiding groove and the clamping groove. Compared with the prior art, the structure of the utility model is simple and the assembly process is less. Through the design concept of forming a guiding groove and a clamping groove on the main body part and arranging a limiting part between the two, not only the problem that the suction pipe assembly of the vacuum cleaner is easy to disconnect during normal straight dragging or twisting is solved, but also the cost reduction and efficiency improvement are beneficial.

[0046] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto.
