Description

Technical Field

[0001] This utility model relates to the field of household cleaning technology, and in particular to a vacuum cleaning accessory device that prevents lint from getting tangled. Background Technology

[0002] Vacuum cleaners are becoming increasingly indispensable for household cleaning in China, and cleaning accessories are used in conjunction with them. However, existing cleaning accessories use a high-speed rotating roller brush with a clearance fit between the bracket and the end cap. Due to the precision limitations, it is difficult to guarantee that there will be no slight wobbling. If the clearance is too small, friction will occur, generating resistance; if the clearance is too large, long hair will pass through the gap and directly enter between the end cap and the bracket. Over time, this can cause minor noises or, in severe cases, the roller brush may become stuck, affecting the reliability of the cleaning accessory. A similar technology can be found in Chinese Invention Publication Patent CN106725101A, therefore, improvement is necessary. Utility Model Content

The roller brush fixing seat 2300 includes a bearing chamber 2320 located therein and a receiving chamber 2340 communicating with the bearing chamber 2320. The non-drive mating component 2500 includes a central portion 2520 located at the center and having a central shaft hole 2524 that can be inserted into the roller brush cavity 2020, and an annular non-drive mating outer edge 2540 located on the outer side. The drive end cover 2600 includes a drive end cover cavity 2604 surrounding the bearing chamber 2320, a drive shaft head 2620 surrounded by the drive end cover cavity 2604, and a transmission gear 2640 for transmission. The drive shaft head 2620 is provided with a plurality of shaft head holes 2624. The drive mating member 2700 includes a plurality of mating claws 2720 located at one end and received by the receiving chamber 2340 and axially engaging with the corresponding shaft head holes 2624, a drive mating outer edge surrounding the mating claws 2720 and forming an annular shape, and a mating shaft end 2740 located at the other end and inserted into the inner cavity 2020 of the roller brush. The roller brush assembly 2000 also includes a blocking member 2800 located outside the non-drive mating member 2500 or the drive mating member 2700 and between the non-drive end cover 2400 and the drive end cover 2600. The blocking member 2800 is disposed on the outer edge of the non-driving mating member 2500 or the driving mating member 2700, i.e., on the outer edge of the non-driving mating member 2540 or the outer edge of the driving mating member, and is made of a fluffy material and is annular. The roller brush assembly 2000 also includes a plurality of bearings 2900, wherein the bearing 2900 axially disposed between the non-driving end cover 2400 and the non-driving mating member 2500 is a non-driving bearing, while the bearing 2900 axially disposed between the driving end cover 2600 and the driving mating member 2700 is a driving bearing. The roller brush assembly 2000 also includes a drive shaft 2940 axially passing through the center of the driving bearing and the driving mating member 2700, and a rotation shaft 2944 axially passing through the center of the non-driving bearing and the non-driving mating member 2500. The bearing housing 2320 further accommodates the bearings 2900. One end of the drive shaft 2940 passes through the drive end cover 2600, the bearing housing 2320, and the housing 2340 and is fixedly connected to the drive shaft portion 2620.

[0031] The power unit 3000 is preferably a DC motor, more preferably a DC brushless motor, located between the brush chamber 1200 and the adapter 4000. Its center direction is parallel to the center direction of the brush body. The power unit 3000 outputs power through one end of the transmission unit 3200, while the other end of the transmission unit 3200 is connected to the transmission gear 2640, causing the brush body to rotate around an axis parallel to the horizontal plane.

[0032] The other end of the adapter 4000 is connected to the vacuum cleaner main unit or vacuum hose to supply the dirty airflow from the roller brush chamber 1200 to the vacuum cleaner main unit.

[0033] Based on the first embodiment, this utility model further includes a second embodiment, wherein the difference between the second embodiment and the first embodiment is that the power component is omitted. Specifically, it includes an accessory seat with a brush cavity and a brush assembly disposed in the brush cavity and rotating about an axis. The brush assembly includes a brush body, a pair of end caps located on both sides of the brush body, and a pair of end cap mating parts that radially clearance fit with the corresponding end caps. The brush assembly also includes an annular blocking member located outside the corresponding end cap mating parts and between the corresponding end caps, wherein the blocking member is made of soft material and prevents the axial movement of hair. Because the blocking member and the end caps are interference-fitted and the blocking member is soft, the resistance generated when the brush body rotates at high speed is small. Long hairs will be stuck on this blocking member, preventing long hairs from entering between the end caps and the end cap mating parts, and further preventing the brush body from jamming.

[0034] The advantages of this invention are: it prevents hair from entering the end cap, reduces hair tangling, and ensures the reliability of the roller brush assembly.

[0035] The above are merely preferred embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any modifications and improvements made by those skilled in the art without departing from the inventive concept of the present utility model should be covered within the protection scope of the present utility model.
