Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaners, and in particular to a silent vacuuming floor brush. Background Technology

[0002] With vacuum cleaners becoming increasingly popular, their refined design is becoming more crucial to improving the user experience. The floor brush, which constantly moves back and forth on the floor, has casters that rotate at high speed during use. This constant friction between the plastic and metal creates noise, significantly impacting the user experience. To address this, some manufacturers place felt on both sides of the casters to prevent axial wobble. However, felt easily attracts hair, which can become entangled in the casters after prolonged use, causing them to jam and hindering usability. A similar technology can be found in Chinese utility model patent CN204192513U. Utility Model Content

[0003] To address the aforementioned shortcomings, this invention provides a silent dust-collecting floor brush that reduces noise during operation, prevents casters from getting stuck with hair, and is convenient for users.

[0004] To achieve the purpose of this utility model, the present utility model proposes the following technical solution: a silent dust-collecting floor brush, comprising a floor brush seat having a brush chamber and capable of reciprocating on a horizontal plane, a brush body located in the brush chamber and capable of rotation, a roller located on the rear side of the brush body, and a caster located on the front side of the brush body, wherein the caster comprises a wheel body made of hard plastic material and a rubber coating body located on the outside of the wheel body and made of soft plastic material.

[0005] Based on the above technical solution, the following supplementary technical solutions are further included:

[0006] The floor brush holder also includes a mounting groove located on the front side of the roller brush body, wherein the cross section of the mounting groove is cross-shaped.

[0007] The mounting groove includes a caster groove for receiving casters and an axle groove that intersects and communicates with the caster groove.

[0008] It also includes the axle, which passes through the center of the wheel body, is contained in the axle slot, and is made of rigid material.

[0009] The axle groove is closer to the horizontal plane than the inner side of the caster wheel groove.

[0010] The diameter of the roller is larger than the diameter of the brush body, and the diameter of the brush body is larger than the diameter of the caster.

[0011] It also includes multiple air inlets located on the front side of the roller brush chamber and interconnected with each other, as well as multiple dividing ribs for separating adjacent air inlets, wherein the caster is arranged adjacent to an air inlet.

[0012] The cross-section of the dividing rib is triangular.

[0013] The air inlet is funnel-shaped, and the caster is adjacent to the upstream side of the air inlet.

[0014] It also includes a base end located at the rear end of the floor brush holder, wherein the rollers are fixedly connected to both sides of the base end and located at the rear end of the floor brush holder, while the casters are located at the front end of the floor brush holder; wherein the width of the casters ranges from 1 to 6 mm, and the diameter ranges from 10 to 20 mm.

[0015] The beneficial effects of this utility model are: reducing abnormal noise during operation, preventing casters from being jammed by hair, and making it easier for users to use. Attached Figure Description

[0022] Example: Figure 1-2 As shown, this utility model discloses an embodiment of a silent vacuum floor brush, which includes a floor brush base 1000 having a roller brush chamber 1200 and capable of reciprocating on a horizontal plane, a rotatable roller brush body 2000 located in the roller brush chamber 1200, a roller 1800 located at the rear of the roller brush body 2000, a caster 3000 located at the front of the roller brush body 2000, and a connector 4000 rotatably connected to the rear end of the floor brush base 1000. The other end of the connector 4000 is connected to a connecting pipe or the main unit of a vacuum cleaner. The connector 4000 can rotate relative to the floor brush base 1000 in the front-back or left-right direction, and one end of its interior is connected to the roller brush chamber 1200.

[0023] The floor brush holder 1000 is generally T-shaped and includes a brush chamber 1200 at the front, a plurality of air inlets 1400 located at the front of the brush chamber 1200 and interconnected therewith, a plurality of dividing ribs 1500 for separating adjacent air inlets, a base end 1600 at the rear of the floor brush holder 1000, a pair of mounting grooves 1700 located at the front of the brush body 2000, and a pair of rollers 1800 fixedly connected to both sides of the base end 1600. Each mounting groove 1700 has a cross-shaped cross section. The mounting groove 1700 includes a caster sub-groove 1720 for accommodating casters 3000 and an axle sub-groove 1740 that intersects and communicates with the caster groove 1720. The axle groove 1740 is closer to the horizontal plane than the inner side of the caster groove 1720. The diameter of roller 1800 is larger than the diameter of brush body 2000, and the diameter of brush body 2000 is larger than the diameter of caster 3000. Each caster 3000 is adjacent to a corresponding air inlet 1400. The cross-section of the dividing rib 1500 is triangular. The air inlet 1400 is flared, with the caster 3000 adjacent to the upstream side of the air inlet 1400. The rearward extension direction of the base end 1600 intersects perpendicularly with the central direction of the brush chamber 120. Rollers 1800 are fixedly connected to both sides of the base end 1600 and located at the rear end of the brush base 1000, while casters 3000 are located at the front end of the brush base 1000.

[0024] The caster 3000 includes a central hole 3020, a wheel body 3100 made of rigid plastic, an axle 3200 made of rigid material that passes through the central hole 3020 and is received by an axle groove 1740, and a rubber-coated body 3300 made of soft plastic located outside the wheel body 3100. The wheel body 3100 has an axial flange 3120 around the central hole 3020 to support the axle 3200. The wheel body 3100 is preferably made of POM (polyoxymethylene), as POM has self-lubricating properties that effectively reduce friction. The axle 3200 is preferably a metal axle. The caster 3000 has a width ranging from 1 to 6 mm, reducing the contact area between the caster and the ground and achieving point contact, which effectively reduces noise caused by the caster spinning freely on uneven ground. The diameter of the 3000 casters ranges from 10-20 mm, reducing the wheel's rotation speed. Smaller diameter wheels rotate many more times than larger diameter wheels. Therefore, larger diameter wheels effectively reduce friction caused by high-speed rotation during floor brush use, and friction is the root cause of wheel noise.

[0025] The advantages of this utility model are: by changing the physical characteristics of the casters, the noise generated during use is improved, without the need for additional actions such as adding wool felt or applying oil to the small wheel axles with a floor brush, which can effectively reduce costs and noise; furthermore, it improves the user experience, with refined design enhancing product quality, preventing casters from being jammed by hair, and making it easier for users to use.

[0026] 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.
