Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaners, and more specifically to a vacuum cleaner accessory with support wheels. Background Technology

[0002] Vacuum cleaner accessories are used in conjunction with vacuum cleaners and include floor brushes and various nozzles. Since floor brushes need to move back and forth on the surface to be cleaned, their mobility and vacuuming ability are particularly crucial. Generally, floor brushes that are easy to move tend to have weaker vacuuming capabilities, while those with stronger vacuuming capabilities tend to have weaker mobility. Similar technology can be found in Chinese utility model CN203506607U, therefore, improvements are necessary. Utility Model Content

[0003] The purpose of this invention is to provide a vacuum cleaner accessory with support wheels that can effectively solve the above-mentioned technical problems, satisfying both vacuum cleaning capability and mobility, and reducing excessive pressure deformation of the rubber strap.

[0004] To achieve the purpose of this utility model, the following technical solution is adopted: a vacuum cleaner accessory with support wheels, comprising a floor brush seat having a suction chamber and capable of reciprocating on a horizontal plane, a floor brush cover plate connected to the floor brush seat and used to cover the top of the floor brush seat, a pair of rollers disposed on the rear side of the floor brush seat, a pair of casters disposed at the bottom of the floor brush seat and located at the front end of the suction chamber, and a support wheel disposed at the bottom of the floor brush seat and located between the suction chamber and the rollers.

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

[0006] The diameter of the support wheel is larger than that of the caster but smaller than that of the roller.

[0007] The axial length of the roller is greater than that of the caster, but less than that of the support wheel.

[0008] It also includes a movable plate disposed between the brush holder and the brush cover and capable of reciprocating vertically and horizontally, wherein the movable plate includes a bristle strip located at the front end and a leather strip located at the rear end and parallel to the bristle strip.

[0009] The support wheel is located between the leather strap and the roller.

[0010] The caster is located between the brush strip and the dust collection chamber.

[0011] It also includes an adapter that is movably connected to the floor brush holder, wherein the floor brush holder is provided with a connection channel at one end connected to the dust collection chamber, and the other end of the connection channel is connected to the interior of the adapter.

[0012] The axial length of the support wheel is greater than 1 / 6 of the front end length of the floor brush holder and less than 1 / 3 of the front end length of the floor brush holder.

[0013] The diameter of the casters ranges from 6 to 12 mm, the diameter of the support wheels ranges from 10 to 16 mm, and the diameter of the rollers ranges from 40 to 60 mm.

[0014] The axial length of the roller is 10-20 mm, the axial length of the support wheel is 40-60 mm, and the axial length of the caster is 6-12 mm.

[0015] Compared with the prior art, the present invention has the following advantages: it can satisfy both vacuum dust collection capability and movement flexibility, reduce excessive pressure deformation of the leather strip, ensure the working reliability of the leather strip, and ensure vacuum sealing, thereby improving vacuum dust removal capability.

The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 4 As shown, this utility model provides an embodiment of a vacuum cleaner accessory with support wheels, which includes a floor brush seat 100 having a suction chamber 120 and capable of reciprocating on a horizontal plane, a floor brush cover plate 200 connected to the floor brush seat 100 and used to cover the top of the floor brush seat 100, a movable plate 300 disposed between the floor brush seat 100 and the floor brush cover plate 200 and capable of reciprocating vertically to the horizontal plane, a pair of rollers 420 disposed on the rear side of the floor brush seat 100, a pair of casters 440 disposed at the bottom of the floor brush seat 100 and located at the front end of the suction chamber 120, a support wheel 400 disposed at the bottom of the floor brush seat 100 and located between the suction chamber 120 and the rollers 420, and an adapter 500 movably connected to the floor brush seat 100.

[0024] The floor brush holder 100 is generally rectangular and is an injection-molded part. The suction chamber 120 is located at the front end of the floor brush holder 100, and includes a connecting channel 140 with one end connected to the suction chamber 120, and the other end of the connecting channel 140 connected to the interior of the adapter 500. The connecting channel 140 extends in a front-to-back direction, that is, from the front end of the floor brush holder 100 to the rear end. In this embodiment, the connecting channel 140 is preferably a flexible hose to deliver dust-laden airflow.

[0025] The floor brush cover 200 is used to cover the top of the suction chamber 120 and to prevent the connecting channel 140 from being exposed.

[0026] The movable plate 300 includes a brush strip 320 at the front end and a leather strip 340 at the rear end, parallel to the brush strip 320. The leather strip 340 is located on the rear side of the suction chamber 120 and is disposed adjacent to the support wheel 400. The movable plate 300 may have at least two positions in the vertical direction, in one position where the brush strip 320 and leather strip 340 are in contact with the surface to be cleaned, and in another position where the brush strip 320 and leather strip 340 maintain a vertical gap with the surface to be cleaned.

[0027] The support wheel 400 is located between the bristle strip 340 and the roller 420. The diameter of the support wheel 400 is larger than the diameter of the caster 440 but smaller than the diameter of the roller 420. The axial length of the roller 420 is larger than the axial length of the caster 440 but smaller than the axial length of the support wheel 400. The caster 440 is located between the bristle strip 320 and the suction chamber 120. The axial length of the support wheel 400 is greater than 1 / 6 of the front end length of the floor brush holder 100 and less than 1 / 3 of the front end length of the floor brush holder 100. The diameter of the caster 440 ranges from 6 to 12 mm, the diameter of the support wheel 400 ranges from 10 to 16 mm, and the diameter of the roller 420 ranges from 40 to 60 mm. The axial length of the roller 420 is 10 to 20 mm, the axial length of the support wheel 400 is 40 to 60 mm, and the axial length of the caster 440 is 6 to 12 mm. Since the support wheel 400 is arranged adjacent to the belt 340, excessive pressure deformation of the belt 340 is reduced, ensuring the working reliability of the belt 340 and ensuring vacuum sealing, thereby improving vacuum dust removal capability.

[0028] This utility model enhances the movement flexibility of this embodiment by using casters at the front end, rollers at the rear end, and support wheels between the casters and rollers. Furthermore, by switching the position of the movable plate, the vacuum dust removal capability of this embodiment can be increased, excessive pressure deformation of the leather strip can be reduced, the working reliability of the leather strip can be guaranteed, and the vacuum sealing performance can be ensured, thereby improving the vacuum dust removal capability.

[0029] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0030] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
