Description

Technical Field

[0001] The present invention relates to the field of handheld vacuum cleaners, and more particularly, to a split-type handheld vacuum cleaner. Background Art

[0002] A handheld vacuum cleaner is a newly emerging vacuum cleaner product. It is generally small in size, convenient to carry and use, and is a vacuum cleaner product between ordinary household vacuum cleaners and portable vacuum cleaners. Handheld vacuum cleaners are more suitable for cleaning small spaces, such as cleaning inside a car, narrow spaces in a home, or the workbench area in an office.

[0003] In current handheld vacuum cleaners, the main components include a main body and a dust cup assembly, and the dust cup assembly is integrated on the main body. In some existing handheld vacuum cleaners, the dust cup assembly is mainly assembled and disassembled by rotating it out or unlocking it (by snap connection). The main problem with the existing connection methods between the dust cup assembly and the main body is that gaps are likely to occur at the connection between the main body and the dust cup. During use, due to the driving of the motor in the main body, the dust cup is prone to shaking, which will affect the firmness of the fixation of the dust cup assembly on the main body. Summary of the Invention

[0004] In view of this, the present invention provides a split-type handheld vacuum cleaner, and the main improvement lies in improving the connection structure between the dust cup assembly and the vacuum cleaner main body. Specifically, an interlocking slide rail connection method is adopted for assembly. That is, during installation, the dust cup is pushed into the installation space of the main body through the slide rail, and during disassembly, the dust cup is pulled out of the installation space of the main body through the slide rail. Based on the interlocking structure of the slide rail, the installation of the dust cup on the main body is more stable, and the problem of dust cup shaking due to installation gaps will not occur.

[0005] To this end, the present invention provides a split-type handheld vacuum cleaner, which includes a vacuum cleaner main body and a dust cup assembly. A holding handle extends outward from the first end of the vacuum cleaner main body, and a dust cup connection portion extends outward from the opposite second end. The dust cup connection portion has a first slide rail, and the dust cup assembly is provided with a second slide rail that is inserted into the first slide rail. The dust cup assembly is detachably connected to the vacuum cleaner main body through the first slide rail and the second slide rail.

[0006] Further, the dust cup connection portion extends axially outward along the vacuum cleaner main body, and the first slide rail is arranged along the length direction of the dust cup connection portion.

[0007] Further, an L-shaped structure is formed between the dust cup connection portion and the vacuum cleaner main body. A dust cup installation space is formed between the lower part of the dust cup connection portion and the second end of the vacuum cleaner main body, and the dust cup assembly is assembled in the dust cup installation space.

[0008] Further, the second slide rail is arranged along the axial direction of the dust cup assembly.

[0009] Further, the dust cup assembly includes a dust cup and an air duct. A filtering component is arranged inside the dust cup. The air duct is integrated at the outer end of the dust cup. The air inlet of the air duct extends outward from the outer end of the dust cup, and the air outlet of the air duct extends into the dust cup.

[0010] Further, the dust cup includes a cup body and a cup cover with any plane in the height direction of the dust cup as the dividing surface. The air duct is integrated at the outer end of the cup body.

[0011] Further, the cup body covers at least three sides of the dust cup.

[0012] Further, a plate body is provided on the outer side of the cup body. A gap is formed between the plate body and the outer wall of the cup body, and a second slide rail is formed in the gap.

[0013] Further, the cup cover covers at least three sides of the dust cup.

[0014] Further, the filtering component is detachably inserted into the dust cup through an assembly hole provided at the inner end of the dust cup.

[0015] In a split-type handheld vacuum cleaner provided by the present invention, the main improvement lies in improving the connection structure between the dust cup assembly and the vacuum cleaner main body. An inter-inserted slide rail connection method is adopted for assembly. Specifically, a first slide rail is provided on the dust cup connection part, and a second slide rail inserted opposite to the first slide rail is provided on the dust cup assembly. The dust cup assembly is detachably connected to the vacuum cleaner main body through the first slide rail and the second slide rail. During installation, the dust cup is pushed into the installation space of the main body through the slide rail. During disassembly, the dust cup is pulled out of the installation space of the main body through the slide rail in the same way.

[0016] Therefore, compared with the prior art, the split-type handheld vacuum cleaner provided by the present invention does not dirty hands when cleaning or replacing the dust cup, and due to the inter-inserted structure of the slide rail, the installation of the dust cup on the main body is more stable, and the problem of the dust cup shaking due to the installation gap will not occur.

[0027] Refer to Figures 1 to 6 , specifically, the dust cup connection portion 14 extends outward along the axial direction of the vacuum cleaner main body 1, and the first slide rail 141 is arranged along the length direction of the dust cup connection portion 14.

[0028] Refer to Figures 1 to 6, specifically, an L-shaped structure is formed between the dust cup connecting portion 14 and the vacuum cleaner main body 1, and a dust cup installation space is formed between the lower part of the dust cup connecting portion 14 and the second end 13 of the vacuum cleaner main body 1. The dust cup assembly 2 is assembled in the dust cup installation space.

[0029] See Figures 1 to 6 , specifically, the second slide rail 21 is arranged along the axial direction of the dust cup assembly 2.

[0030] In a split-type handheld vacuum cleaner provided in this embodiment, its main improvement lies in improving the connection structure between the dust cup assembly and the vacuum cleaner main body, and adopting an interlocking slide rail connection method for assembly. Specifically, the dust cup connecting portion is provided with a first slide rail, and the dust cup assembly is provided with a second slide rail that is inserted into the first slide rail. The dust cup assembly is detachably connected to the vacuum cleaner main body through the first slide rail and the second slide rail; during installation, the dust cup is pushed into the installation space of the main body through the slide rail; during disassembly, the dust cup is pulled out of the installation space of the main body through the slide rail as well.

[0031] Therefore, compared with the prior art, the split-type handheld vacuum cleaner provided in this embodiment does not dirty hands when cleaning or replacing the dust cup, and due to the interlocking structure of the slide rails, the dust cup is more firmly installed on the main body and will not shake due to installation gap problems. Embodiment Two:

[0032] See Figures 1 to 6 , the figure shows a split-type handheld vacuum cleaner provided in Embodiment Two of the present invention. On the basis of the above embodiment, the following further improved technical solutions are made: The dust cup assembly 2 includes a dust cup 22 and an air duct 23. A filtering component 24 is arranged in the dust cup 22. The air duct 23 is integrated at the outer end of the dust cup 22, and the air inlet 231 of the air duct 23 extends outward from the outer end of the dust cup 22, and the air outlet 232 of the air duct 23 extends into the dust cup 22. Through the setting of the above structure, the air duct is directly integrated on the dust cup, and the air flow no longer needs to pass through the main body and then enter the dust cup, which can effectively increase the speed of the air flow entering the dust cup and help improve the cleaning efficiency. Embodiment Three:

[0033] See Figures 1 to 6 , the figure shows a split-type handheld vacuum cleaner provided in Embodiment Three of the present invention. On the basis of the above embodiment, the following further improved technical solutions are made: The dust cup 22 includes a cup body 221 and a cup cover 222 with any plane in the height direction of the dust cup 22 as the dividing surface. The air duct 23 is integrated at the outer end of the cup body 221.

The cup body 221 occupies three side surfaces of the dust cup 22, and the cup cover 222 occupies three side surfaces of the dust cup 22; more preferably, the cup body 221 and the cup cover 222 can respectively occupy half of the area of the dust cup 22; while ensuring the expansion of the cleaning area, the sealing performance is also guaranteed.

[0035] In some other embodiments, the dust cup 22 can also be circular, polygonal cylinder, etc. In order to enhance the sealing performance, the cup body 221 can occupy two side surfaces of the dust cup 22, and the cup cover 222 can occupy four side surfaces of the dust cup 22; and so on, the cup body 221 and the cup cover 222 can respectively occupy several side surfaces of the dust cup 22.

[0036] Taking any plane along the height direction of the dust cup as the dividing surface to divide out the cup body and the cup cover, and the cup cover is detachably connected to the cup body. A sealing component is arranged on the edge of the cup body. The first end of the cup body is connected to the vacuum cleaner main body, and an assembly hole is provided on the first end. A filtering component is detachably installed in the assembly hole; that is to say, the cup cover is located on the side surface of the dust cup, so the opening area of the cup cover can be greatly enlarged, making the originally narrow gap area open; therefore, it is more convenient for users to clean the inside of the dust cup, and dust is not easily left in the dust cup. Embodiment 4:

[0037] See Figures 1 to 6 , which shows a split handheld vacuum cleaner provided by the fourth embodiment of the present invention. On the basis of the above embodiments, the following technical solutions are further improved: The outer side of the cup body 221 has a plate body 223, and a gap is formed between the plate body 223 and the outer wall of the cup body 221, and a second slide rail 21 is formed in the gap. Through the improvement of the above structure, a more stable connection between the first slide rail and the second slide rail can be ensured, and further, the installation of the dust cup on the main body is more stable, and the problem of the dust cup shaking due to the installation gap will not occur.

[0038] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
