Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a portable vacuum cleaner assembly. Background Technology

[0002] Vacuum cleaners remove dust, purify the air, clean fine dust and debris from corners, and clean more thoroughly, saving time, reducing housework stress, and shortening cleaning time. Vacuum cleaners are usually equipped with mite-removal brushes to vacuum, sterilize, and remove mites from floors. However, current vacuum cleaners use wind-driven floor brushes; ordinary floor brushes are not specifically designed for mite removal. They can become very dirty on carpets and floors, and can contaminate furniture like beds and sofas when used for cleaning. Furthermore, the strong suction of ordinary floor brushes can trap sheets and sofa covers, hindering the cleaning process. Utility Model Content

[0003] The purpose of this utility model is to provide a portable vacuum cleaner component. This portable vacuum cleaner component can remove mites and vacuum, and it is easy to rotate the sleeve within an appropriate range to adapt to various usage scenarios. It can also adjust the actual air inlet size and suction power, and can keep the lower opening and the surface to be cleaned in a horizontal fit at all times, thereby improving the cleaning and vacuuming effect.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a portable vacuum cleaner assembly, comprising: a housing with a mounting cavity at the bottom, an inner suction tube communicating with the mounting cavity through an air inlet opened at the upper part of the housing, a roller brush, a drive assembly, and an air guide tube for connecting with the vacuum cleaner body. An outer sleeve is provided on the outside of the inner suction tube. In addition, a first connecting tube is sealed and connected to the inner suction tube at the end away from the air inlet. The other end of the air guide tube, one end of which is connected to the vacuum cleaner body, is connected to a second connecting tube that is inserted into and cooperates with the first connecting tube. The end of the second connecting tube opposite to the air guide tube can be inserted into the outer sleeve.

[0005] A sleeve is installed inside the mounting cavity, whose inner wall is set as an arc surface. The roller brush is rotatably installed inside the sleeve. The upper and lower parts of the sleeve, which can rotate relative to the housing, are respectively provided with an upper opening and a lower opening that communicate with the inside of the sleeve. The inner diameter of the upper opening, which is provided corresponding to the air inlet, is greater than or equal to the inner diameter of the air inlet. The lower opening is a strip-shaped opening extending along the length direction of the roller brush. At least one long side of the lower opening has a horizontally outwardly extending flange strip. The lower surface of the flange strip, which rotates with the sleeve, is used to contact the surface to be cleaned. The middle area of ​​at least one flange strip has a bent portion extending towards the housing. A stop groove that mates with the bent portion is provided on the housing.

[0006] The following are further improvements to the above technical solution:

[0007] 1. In the above solution, the air duct further includes an inner tube and an outer tube sleeved outside the inner tube. At least one wiring terminal is provided inside the outer tube and outside the first connecting tube. At least one electrical contact post that mates with the wiring terminal is provided outside the second connecting tube. The other end of the electrical contact post, which is electrically connected to the wiring terminal at one end, is electrically connected to the dust collection body through a wire provided between the inner tube and the outer tube of the air duct.

[0008] 2. In the above scheme, the inner and outer pipes of the air guide duct are eccentrically arranged.

[0009] 3. In the above scheme, the second connecting pipe is sealed to the inner pipe of the air duct.

[0010] 4. In the above scheme, a sealing ring is provided between the inner suction tube and the first connecting tube, and between the first connecting tube and the second connecting tube.

[0011] 5. In the above scheme, the upper opening is an oblong hole, the minor diameter of which is the same as the inner diameter of the circular air inlet, and the major diameter is greater than the inner diameter of the air inlet.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0013] This utility model relates to a portable vacuum cleaner assembly. An outer sleeve is provided outside the inner suction tube. A first connecting tube is sealed and connected to the end of the inner suction tube furthest from the air inlet within the outer sleeve. A second connecting tube, which is inserted into and mates with the first connecting tube, is connected to the other end of an air guide tube connected at one end. The end of the second connecting tube opposite to the air guide tube can be inserted into the outer sleeve. A sleeve is housed within a mounting cavity with an arc-shaped inner wall. A roller brush is rotatably mounted within this sleeve. The upper and lower parts of the sleeve, which can rotate relative to the housing, have upper and lower openings respectively, each communicating with the interior of the sleeve. The inner diameter of the upper opening, corresponding to the air inlet, is greater than or equal to the inner diameter of the air inlet. The lower opening is a strip-shaped opening extending along the length of the roller brush. The lower opening has a horizontally extending outward flange at the edge of at least one long side. The lower surface of the flange, which rotates with the sleeve, is used to contact the surface to be cleaned. The middle area of ​​at least one flange has a bent portion extending towards the housing. A stop groove that mates with the bent portion is provided on the housing. In addition to achieving mite removal and dust removal, this design allows the user to easily rotate the sleeve to adapt to various usage scenarios, while also limiting the rotation of the sleeve to an appropriate range. Furthermore, the rotation of the sleeve can be used to adjust the overlapping area between the upper opening and the air inlet, thereby adjusting the actual air inlet size and suction power to meet different usage scenarios. It also ensures that the lower opening and the surface to be cleaned remain in a horizontal fit, improving the cleaning and dust removal effect. Attached Figure Description
