TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning tools, in particular to a desktop vacuum cleaner. BACKGROUND

[0002] The desktop vacuum cleaner is a small and convenient cleaning tool, which is usually used in offices, furniture surfaces, home work periphery, computer desktop keyboards and other occasions. With the development of the times, the desktop vacuum cleaner has become a common tool in people's daily life.

[0003] The current desktop vacuum cleaner is usually driven by a motor, and dust and debris are sucked into the dust collection bin by suction force. However, since the dust collection bin is fixed with the main part of the vacuum cleaner, most of the dust collection bin is difficult to clean during the cleaning process. CONTENT OF THE INVENTION

[0004] The purpose of the present application is to provide a desktop vacuum cleaner to improve the problem that the dust collection bin is difficult to clean.

[0007] By adopting the above technical scheme, when the desktop vacuum cleaner needs to be cleaned, the dust collection bin can be removed for cleaning. Meanwhile, the added dust collection ring layer can adsorb a certain amount of dust, so that the cleaning work of the entire dust collection bin can be more quickly and effectively realized by replacing or cleaning the dust collection ring layer.

[0008] Optionally, the outer and inner circles of the dust collection ring layer are respectively provided with a first hard ring and a second hard ring, the first hard ring is in close contact with the inner side wall of the dust collection bin, and the second hard ring is in close contact with the outer side wall of the negative pressure air pipe.

[0009] By adopting the above technical scheme, the inner and outer circles of the dust collection ring layer are respectively supported by the first and second hard rings, which effectively close the inner side wall of the dust collection bin and the outer side wall of the negative pressure air pipe, thereby further reducing the entry of dust into the bottom wall of the dust collection bin.

[0010] Optionally, the first and second hard rings are made of steel material, the inner side wall of the dust collection bin is provided with a first magnetic member which is magnetically attracted to the first hard ring, and the outer side wall of the negative pressure air pipe is provided with a second magnetic member which is magnetically attracted to the second hard ring.

[0011] By adopting the technical scheme, when the dust collecting bag is installed, the hard rings of the inner ring and the outer ring of the dust collecting bag are attracted to the magnetic members of the inner side wall of the dust collecting bin and the outer side wall of the negative pressure air pipe, and are doubly fixed, thereby improving the stability of the dust collecting ring layer.

[0012] Optionally, the surface of the first magnetic member attracted to the first hard ring and the surface of the second magnetic member attracted to the second hard ring are provided with rubber layers.

[0013] By adopting the technical scheme, the rubber layer is arranged on the surface of the magnetic member, so that the force generated when the magnetic member is attracted to the hard ring is prevented from intensifying the magnetic member and the hard ring, and the possibility of the user being pinched in the installation process is effectively reduced.

[0014] Optionally, the first hard ring is provided with a lifting handle.

[0015] By adopting the technical scheme, when the dust collecting ring layer needs to be taken, the lifting handle is pinched and lifted upward, so that the hard ring of the dust collecting ring layer is separated from the magnetic member of the dust collecting bin, thereby realizing the convenience of taking the dust collecting ring layer.

[0016] Optionally, the machine shell is provided with a motor bin at the top of the dust collecting bin, the motor bin is provided with a driving member, the top of the motor bin is provided with a filter bin, the filter bin is provided with a filter element, and the lower portion of the filter bin is provided with a first air outlet.

[0017] By adopting the technical scheme, after the dust is coarsely filtered by the dust collecting bin, the dust is finely filtered by the filter element.

[0018] Optionally, the filter element is in a hollow shape, and a sealing cover is arranged on the upper portion of the filter element.

[0019] By adopting the technical scheme, the air is discharged after passing through the filter element.

[0020] Optionally, the machine shell is provided with a detachable sealing plate above the sealing cover, the sealing plate abuts against the sealing cover, and the sealing plate is provided with a plurality of second air outlets.

[0021] By adopting the technical scheme, the sealing plate fixes the sealing cover and the filter element.

[0022] Optionally, the machine shell is provided with a battery bin cover above the sealing plate, the battery bin cover is provided with a plurality of third air outlets, the battery bin cover is provided with a supporting rod, and the supporting rod abuts against the sealing plate.

[0023] By adopting the technical scheme, the sealing plate is fixed twice.

[0024] In summary, the present application has at least one of the following beneficial technical effects:

[0025] 1. When the dust collecting ring layer needs to be taken out from the dust collecting bin, the dust collecting ring layer can be taken out, which is convenient for cleaning the dust collecting bin because the contact between the dust and the inner wall of the dust collecting bin is reduced.

[0026] 2. When the dust collecting ring layer is installed, the hard ring of the inner and outer rings of the dust collecting ring layer is attracted to the magnetic part of the negative pressure air pipe and the inner side wall of the dust collecting bin, and is double-fixed to realize the stability of the dust collecting ring layer.

[0027] 3. When the dust collecting ring layer needs to be taken out, the hard ring of the dust collecting ring layer is separated from the magnetic part of the dust collecting bin by pinching the handle and lifting it upward, so that the dust collecting ring layer is convenient to take out.
