Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaners, specifically to a vacuum floor brush with a lifting device. Background Technology

[0002] Ordinary floor vacuum brushes have a fixed structure, meaning the gap between the brush and the surface to be cleaned is fixed and cannot be adjusted. This results in unsatisfactory cleaning effects on different surfaces, such as carpets and floors. Specifically, if the gap between the brush and carpet is too large, it reduces suction power and affects cleaning performance. Conversely, if the gap is too small on floors, it can cause excessive friction between the brush and the floor, increasing noise and wear. To address these issues, existing technologies have proposed adjustable brush height solutions. However, these solutions suffer from inconvenience in adjustment, poor stability, or limited applicability. A similar technology can be found in Chinese Utility Model Patent CN203914783U. Therefore, improvements are needed. Utility Model Content

[0003] The purpose of this utility model is to provide a vacuum floor brush with a lifting device that can effectively solve the above-mentioned technical problems. It is suitable for use in carpet and floor environments, which not only improves the cleaning effect but also reduces friction. It also has a simple structure and is easy to adjust.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a vacuum cleaner body with a lifting device, comprising a vacuum cleaner body having an air inlet pipe body, a vacuum cup that is connected to one end of the air inlet pipe body and is hollow inside, a motor housing that is connected to the other end of the vacuum cup, is hollow inside and connected to the vacuum cleaner body, a vacuum motor disposed in the motor housing, and a battery housing that is connected to the other end of the motor housing, is hollow inside and connected to the vacuum cleaner body.

[0024] like Figures 1 to 5As shown, this utility model provides an embodiment of a vacuum floor brush with a lifting device, which includes a floor brush cover 100 with a central hole 120 in the cover plate, a floor brush base 200 disposed below the floor brush cover 100 and capable of reciprocating on a horizontal plane, a lifting device 300 disposed between the floor brush cover 100 and the floor brush base 200 and capable of reciprocating in a direction perpendicular to the horizontal plane, and a switching device disposed between the floor brush cover 100 and the lifting device 300 and capable of causing the lifting device 300 to reciprocate. 400, a rotating head 500 movably connected at one end to the brush base 200, a connector 600 movably connected at one end to the other end of the rotating head 500 and connected at the other end to the vacuum pipe, a roller fixing part 540 disposed on the brush base 200 and connected to the rotating head 500, a pair of rollers 560 disposed on both sides of the roller fixing part 540, a guide pipe 700 covered by the rotating head 500 and having one end connected to the interior of the rotating head 500, and a guide part 740 connected to the other end of the guide pipe 700.

[0025] The brush cover 100 is generally rectangular and made of injection-molded material. It extends downward around its perimeter and covers the periphery of the brush base 200. There is a bristle gap between the front end of the brush cover 100 and the brush base 200, allowing the cleaning bristles 840 to pass through. The brush cover 100 is provided with a first receiving portion 140 and a second receiving portion 160 disposed opposite to the first receiving portion 140.

[0026] The floor brush base 200 includes an air inlet 220 for collecting dust from the surface to be cleaned, a floor groove 240 for allowing the cleaning strip 820 to pass through, and a deflector 260 that is connected to the deflector 740 and at least partially shields the air inlet 220.

[0027] The lifting device 300 includes an interference recess 330 on its upper surface, a leather strip groove 340 at one end, a hair strip groove 360 ​​at the other end parallel to the leather strip groove 340, a pair of lifting springs 310 disposed on both sides of the lifting device 300, a lifting device center hole 320 communicating with the center hole 120 of the cover plate, a cleaning leather strip 820 located in the leather strip groove 340 and in contact with the horizontal surface, and a cleaning hair strip 840 located in the hair strip groove 360 ​​and in contact with the horizontal surface. The hair strip groove 360 ​​is located at the front end of the lifting device center hole 320, the leather strip groove 340 is located at the rear end of the lifting device center hole 320, and the lifting springs 310 are located on both sides of the leather strip groove 340.

[0028] The switching device 400 includes a switching button 420 located outside the brush cover 100, a first shaft portion 440 located inside the brush cover 100 and connected to the switching button 420, a first interference portion 450 located at the bottom of the switching button 420 and abutting against the lifting device 300, a U-shaped connecting arm 460 connected at one end to the first shaft portion 440 and at least partially surrounding the central hole 320 of the lifting device, a second shaft portion 470 connected to the other end of the U-shaped connecting arm 460 and located above the lifting spring 310, and a second interference portion 480 disposed at the bottom of the second shaft portion 470. The centers of the first interference portion 450 and the second interference portion 480 are on the same straight line. The first shaft portion 440 is received by the first receiving portion 140, while the second shaft portion 470 is received by the first receiving portion 160. An interference recess 330 is used to receive the first interference portion 450 and the second interference portion 480. The interference recess 330 is closer to the cleaning strip 820 relative to the cleaning strip 840. The middle part of the U-shaped connecting arm 460 and the center direction of the first shaft 440 are parallel to each other.

[0029] When working on a carpet, rotating the switch button 420 forces the first interference part 450 and the second interference part 480 downward, causing the lifting device 300 to move downward toward the carpet. Simultaneously, the lifting spring 310 deforms, and the cleaning strips 840 and 820 are pressurized against the carpet, increasing suction. Under the high-speed rotation of the vacuum motor, dirt and dust inside the carpet enter the guide part 740 through the air inlet 220, then through the guide pipe 700 into the connector 600, and finally through the suction pipe into the vacuum motor of the vacuum cleaner main unit, before being discharged to the outside. When working on a floor, rotating the switch button 420 again causes the lifting spring 310 to return to its original deformation, and the lifting device 300 moves upward away from the floor. The cleaning strips 840 and 820 maintain a gap with the floor, allowing the rollers 560 to move more smoothly, while also collecting dust from the floor through the air inlet 220.

[0030] This invention is suitable for use in both carpet and floor environments, improving cleaning performance and reducing friction. It also features a simple structure and easy adjustment.
