Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and more specifically, to an anti-tangling vacuum cleaner floor brush. Background Technology

[0002] The floor brush of a vacuum cleaner is an important component. It is mainly responsible for contacting the ground and using rotating rollers to roll up dust and debris into the vacuum cleaner.

[0003] Patent document CN217744261U discloses an anti-tangling cleaning device, including a floor brush and a roller brush disposed on the floor brush. The roller brush includes a roller brush shaft and a mop cloth wrapped around the roller brush shaft. The floor brush has a receiving cavity for accommodating the roller brush. The cleaning device also includes a scraping structure disposed on the floor brush. The scraping structure is disposed in the receiving cavity. The scraping structure has a plurality of intercepting teeth arranged at intervals along the axial direction of the roller brush. One end of the intercepting teeth abuts against the roller brush. The projection of the plurality of intercepting teeth on the rotation axis of the roller brush covers the entire length of the mop cloth.

[0004] The above solution uses intercepting teeth to completely sweep the roller brush, intercepting and collecting hair across the entire surface of the roller brush, preventing hair from getting tangled on the roller brush. At the same time, the structural design solves the problem of hair escaping from the gap between two adjacent intercepting teeth. However, the hair intercepted from the roller brush will get tangled and collected on the intercepting teeth, thus clogging the gap between the intercepting teeth and affecting the interception effect. Furthermore, the hair tangled and collected on the intercepting teeth is difficult to remove, requiring the intercepting teeth inside the floor brush to be removed periodically for cleaning, which is quite inconvenient.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-tangling vacuum cleaner floor brush.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an anti-tangling vacuum cleaner floor brush, comprising a housing and a roller brush rotatably connected inside therein, one end of the roller brush having a plurality of teeth, a support shaft and a rotating shaft rotatably connected inside the housing, one end of the support shaft being fixedly connected to a gear one, the gear one meshing with the plurality of teeth, a gear two and a peeling roller being fixedly connected to the peripheral wall of the rotating shaft, the gear two meshing with the gear one, and the peeling roller abutting against the roller brush and rotating in the same direction.

[0008] The present invention is further configured such that: a plurality of the teeth in a circumferential array are arranged on the peripheral wall of the roller brush, and the plurality of teeth, gear one, and gear two have the same thickness and are located on the same plane.

[0009] The present invention is further configured such that: the housing has a dust suction port, and the peeling roller is located above the dust suction port.

[0010] The present invention is further configured such that: the rotational speed of the peeling roller is greater than the rotational speed of the roller brush, and the peeling roller is used to peel off the debris from the surface of the roller brush and apply a force to the debris in the direction close to the dust suction port.

[0011] The present invention is further configured such that the peeling roller is made of nylon.

[0012] The present invention is further configured such that a gap of 0.1mm-0.3mm is left between one end of the peeling roller and the second gear.

[0013] In summary, this utility model has the following beneficial effects: when the roller brush rotates, it can drive the stripping roller to rotate through the gear. Since the stripping roller abuts against the roller brush, the stripping roller can form friction on the surface of the roller brush, thereby stripping hair, dust and other debris from the roller brush. At the same time, it can apply a force to the stripped debris in the direction of the suction port, making it easier for the debris to enter the suction port and improving the cleaning effect of the vacuum cleaner. The hydrophobic treatment of the stripping roller reduces the surface energy of the material, making it less likely for debris to adhere to the surface of the stripping roller, and giving it good self-cleaning ability.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example: Anti-tangling vacuum cleaner floor brush, such as Figures 1-3As shown, the device includes a housing 1 and a roller brush 2 rotatably connected inside it. The roller brush 2 has several teeth 3 arranged in a circumferential array on the peripheral wall of one end of the roller brush 2. A support shaft 4 and a rotating shaft 5 are rotatably connected to the inner wall of the housing 1 near the teeth 3. A gear 6 is fixedly connected to the end of the support shaft 4 away from its rotatable connection with the housing 1. The gear 6 meshes with several teeth 3 on the roller brush 2. A motor is provided inside the housing 1 to drive the roller brush 2 to rotate, so that when the roller brush 2 rotates, it can drive the gear 6 and the support shaft 4 to rotate simultaneously. At this time, the rotation direction of the gear 6 is opposite to that of the roller brush 2.

[0020] like Figures 1-3 As shown, both ends of the rotating shaft 5 are rotatably connected to the inner wall of the housing 1. A gear 2 7 and a stripping roller 8 are fixedly connected to the peripheral wall of the rotating shaft 5. Several teeth 3, gear 1 6, and gear 2 7 have the same thickness and are located on the same plane. Gear 2 7 meshes with gear 1 6, so that when gear 1 6 rotates, it can drive gear 2 7, rotating shaft 5, and stripping roller 8 to rotate simultaneously. At this time, the rotation directions of gear 1 6 and gear 2 7 are opposite, so that the rotation direction of the stripping roller 8 is the same as the rotation direction of the roller brush 2. A gap of 0.1mm-0.3mm is left between one end of the stripping roller 8 and the gear 7 to avoid contact and friction between the stripping roller 8 and the gear 6 and several teeth 3, which would affect the rotation effect. The diameter of the stripping roller 8 is smaller than the diameter of the roller brush 2, so that the rotation speed of the stripping roller 8 is greater than that of the roller brush 2. The surface of the stripping roller 8 abuts against the surface of the roller brush 2. Therefore, while the roller brush 2 is rotating, the stripping roller 8 can rotate and rub quickly on the surface of the roller brush 2, thereby stripping hair and dust and other debris from the roller brush 2 and preventing hair and dust from getting tangled on the roller brush 2.

[0021] like Figure 1 and Figure 2 As shown, the housing 1 has a suction port 9. The roller brush 2 rotates counterclockwise to pick up hair, dust, and other debris from the ground and transport them into the suction port 9. The peeling roller 8 is located diagonally above the roller brush 2 and the suction port 9. Since the rotation direction of the roller brush 2 and the peeling roller 8 is the same, when the peeling roller 8 rotates counterclockwise, the bristles on the surface of the peeling roller 8 can embed into the bristles on the surface of the roller brush 2 and rotate in the opposite direction, thereby peeling off the debris from the roller brush 2 and applying a force close to the suction port 9. This facilitates the entry of the debris peeled off from the roller brush 2 into the suction port 9, improving the cleaning effect of the vacuum cleaner. The peeling roller 8 is made of nylon bristles, which has good wear resistance, making the peeling roller 8 less prone to wear. The densely packed nylon bristles on the surface of the peeling roller 8 are hydrophobic, thereby reducing the surface energy of the peeling roller 8 and achieving good waterproof, oil-proof, and stain-proof effects. This makes it difficult for debris and liquid peeled off from the roller brush 2 to adhere to the peeling roller 8, achieving good self-cleaning ability.

[0022] Working principle: When the vacuum cleaner is working, the motor inside the housing 1 drives the roller brush 2 to rotate counterclockwise. At this time, the meshing of several teeth 3 on the roller brush 2 with gear 6 drives gear 6 and support shaft 4 to rotate clockwise. The meshing of gear 6 with gear 7 drives gear 7, rotating shaft 5 and stripping roller 8 to rotate counterclockwise. Since the bristles on the surface of the stripping roller 8 are embedded in the bristles on the surface of the roller brush 2, the stripping roller 8 can rotate and rub rapidly on the surface of the roller brush 2 while the roller brush 2 is rotating, thereby stripping hair, dust and other debris from the roller brush 2. The stripped debris is then subjected to a force close to the suction port 9, thereby driving the stripped debris into the suction port 9.

[0023] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
