[0048] Embodiment 1:

[0049] See also Figure 1-Figure 2 The utility model provides a vacuum cleaner, comprising:

[0050] Main body 10; A suction motor is installed on the main body.

[0051] A dust cup 20 with an air inlet; the connection relationship between the dust cup and the main body is not limited, but the connection needs to be sealed to ensure the dust collection effect.

[0052] And a suction head 40 detachably coupled to the air inlet; the suction head is preferably a flat-mouthed suction head, which can clean narrow spaces such as gaps.

[0053] The dust cup 20 is detachably combined with a mounting bar 30, and the mounting bar 30 is formed with an embedding groove 301 for receiving the suction head 40, so as to be suitable for at least partially receiving the suction head 40 separated from the air inlet;

[0054] Among them, an escape space 201 is provided on the dust cup 20 to escape the embedding groove 301, so that the embedding groove 301 is recessed toward one side of the dust cup 20.

[0055] In the present invention, the flat nozzle 40 is mounted on the main body through a mounting strip 30, which does not affect the use of the dust cup 20; the use and replacement of the flat nozzle 40 is also more convenient. Compared with other storage methods in the prior art, it does not affect the modeling difficulty of the dust cup 20, is simple and easy to manufacture, reduces the production cost, and can meet the diversity and flexibility of user needs.

[0056] In some embodiments, the suction head 40 is at least partially incorporated into the mounting strip 30, so that the suction head 40 and the mounting strip 30 can be integrated, making the overall shape smoother; the overall structure is more regular and beautiful. The embedding groove 301 does not limit the fixing method of the suction head 40, or a clamping device is set in the embedding groove 301; or the shape of the embedding groove 301 is set to be roughly the same as the suction head 40, so that the suction head 40 is embedded therein through a friction fit.

[0057] In some embodiments, the lower portion of the mounting strip 30 extends axially and radially from the lower portion of the dust cup 20. This arrangement allows the mounting strip 30 to be arranged in the shape of the dust cup 20, with smooth overall lines, thereby preventing the vacuum cleaner from colliding with external objects during operation.

[0058] In some embodiments, a sliding fit structure is provided between the mounting strip 30 and the dust cup 20 to achieve assembly and separation of the two by sliding, and the sliding fit structure includes: a slide groove 302 extending along the axial direction of the dust cup 20; and a slider slidingly fitted with the slide groove 302; the slider 202 is arranged on the dust cup 20, and the slide groove 302 is arranged on the mounting strip 30.

[0059] In some embodiments, the connection between the mounting strip 30 and the dust cup 20 is achieved through sliding fit, so that the mounting strip 30 and the dust cup 20 can be quickly assembled or disassembled.

[0060] In some embodiments, a limiting structure is provided between the mounting strip 30 and the dust cup 20, which can limit the separation of the slider and the slide groove when the slider and the slide groove are in the assembly position; wherein the limiting structure includes a limiting groove 303 and a limiting block 203 that are adapted to each other, the limiting groove 303 is arranged on the mounting strip 30, and the limiting block 203 is arranged on the dust cup 20.

[0061] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, when the slider and the slide groove slide to the assembly position of the dust cup 20 and the mounting strip 30, the limit block 203 enters the limit groove 303; then the continued sliding of the slider is restricted, and the reverse sliding of the slider is also prevented.

[0062] In some embodiments, the lower end of the mounting strip 30 is connected to the dust cup 20 via a lower snap-fit ​​structure, and the lower snap-fit ​​structure includes a lower snap-fitting groove 307 and a lower snap-fitting block 204 that snap-fit ​​with each other, and one of the lower snap-fitting groove 307 and the lower snap-fitting block 204 is configured on the dust cup 20 and the other is configured on the mounting strip 30.

[0063] Here, a lower clamping structure is used to make the connection between the mounting strip 30 and the dust cup 20 more stable and safe, and effectively prevent the mounting strip 30 and the dust cup 20 from separating and falling during the use of the vacuum cleaner.

[0064] In some embodiments, the suction head 40 is at least partially inserted into the embedding groove 301 through the elastic clamping part. The mounting bar 30 is provided with an embedding groove 301, and the suction head 40 is at least partially inserted into the embedding groove 301 through the elastic clamping part. Here, the suction head 40 is installed in the embedding groove 301 and is stored by elastic clamping; this can make the structure simple and the elastic clamping stable and reliable.

[0065] In some embodiments, the elastic clamping portion includes an elastic sheet 304 ; at least one of the elastic sheets 304 is disposed on the side wall of the embedding groove 301 to elastically clamp and fix the suction head 40 entering the embedding groove 301 .

[0066] The specific structure of the elastic sheet 304 is not limited and can be selected according to actual conditions. The installation position and installation method of the elastic sheet 304 are not limited.

[0067] In some embodiments, the elastic sheet 304 is a substrate separated from the side wall, with the tail end not separated from the side wall; the front end of the substrate is inside the embedding groove and is elastically deformed with the tail end as the axis to form an elastic clamp.

[0068] In this embodiment, the elastic sheet 304 is cut directly from the side wall of the embedding groove 301, so that the assembly of the elastic sheet 304 can be directly avoided.

[0069] See also Figure 3 , Figure 5 , Figure 6 As shown, there are two elastic sheets 304, which are symmetrically arranged on the side walls of the embedding groove 301 in the length direction, and clamp the two side surfaces of the suction head 40, with a stable clamping effect and reliable carrying.

[0070] In other embodiments, the elastic sheet 304 may be asymmetrically arranged on the side wall of the embedding groove 301 in the length direction, which is not specifically limited.

[0071] See also Figure 5 , Figure 6 In some embodiments, a protrusion structure is provided between the elastic sheet and the suction head to stabilize the suction head clamping; the protrusion structure includes a first protrusion and a second protrusion whose sides abut against each other when the suction head is in a state of being elastically clamped and fixed. One of the first protrusion and the second protrusion is configured on the elastic sheet, and the other is configured on the suction head.

[0072] In this embodiment, the first protrusion is arranged on the suction head 40, and the second protrusion is arranged on the elastic sheet 304. When the suction head 40 is in the elastic clamping and fixing state, the two protrusions are butted against each other. The protrusions butting against each other on the sides make the clamping more secure. In addition, the two protrusions can be replaced by protrusions and grooves matching each other, so that the connection is more secure.

[0073] See also Figure 3 , Figure 4 , Figure 5In some embodiments, the upper end of the mounting bar 30 is connected to the dust cup 20 detachably to the main body 10 through an upper clamping structure; the upper clamping structure includes an upper clamping groove 306 and an upper clamping block 101 that are clamped together, one of which is configured on the main body 10 and the other is configured on the mounting bar 30. In this embodiment, the mounting bar 30 is provided with two mounting bars in the circumference of the dust cup 20, one of which is located at Figure 4 The first mounting bar is on the right side, and the second mounting bar is on the left side. The first mounting bar is provided with an embedding groove 301 for holding the flat suction cup. The connection method between the second mounting bar and the dust cup 20 is the same as that of the first mounting bar in this embodiment. In other embodiments, the second mounting bar and the dust cup may be installed in a different manner, such as a non-detachable connection method.

[0074] In this embodiment, the dust cup 20 and the main body 10 are detachably connected by means of the mounting strip 30 , which is equivalent to the reinforcing ribs of the dust cup 20 , which not only improves the use strength of the dust cup 20 , but also increases the connection strength between the dust cup 20 and the main body 10 .

[0075] In some embodiments, a columnar interface is configured on the suction head 40 to dock with the air inlet of the dust cup 20. Through the docking of the columnar interface, the columnar interface 401 is equivalent to the air inlet of the dust cup 20, and the docking sealing effect is good. The other end of the suction head 40 is configured with a flat suction port 402. The flat suction port is mainly used to clean narrow spaces such as narrow gaps.

[0076] In some embodiments, the vacuum cleaner is a cordless upright vacuum cleaner.

[0077] In some embodiments, the embedding groove 301 is opened to match the shape of the suction head 40. The embedding groove 301 can be opened according to the curved surface of the suction head 40, so that the suction head 40 can form a whole when entering the embedding groove 3011, further making the suction head 40 more regular when carried or stored; such a setting can reduce the suction head 40 from falling.

[0078] In the utility model, a mounting strip 30 detachably connected to the vacuum cleaner is added, and a suction head 40 detachably connected to the mounting strip 30 is used, so that the shape of the dust cup 20 is simplified and the cost is reduced. At the same time, flexible selection of usage modes is achieved, and the storage of the flat suction cup is more convenient. The loss of the flat suction cup is effectively prevented, and the use is convenient.
