Description

Technical Field

[0001] The utility model belongs to the technical field of drum brushes, and particularly relates to a double-drum reciprocating swing brush. Background Art

[0002] Vacuum cleaners are widely used in many production and living sites. By rotating the floor brush drum and wiping it against the floor to be cleaned, the dust and various fine lint accumulated on the floor are swept or adsorbed, thus forming a clean floor. During the cleaning process, due to the fineness of dust and the easy adhesiveness of lint, a lot of dust and debris often adhere to the surface of the floor brush drum. Over time, the cleaning efficiency of the floor brush drum during the cleaning process will decrease. Therefore, users need to regularly take out the floor brush drum from the housing of the vacuum cleaner to conveniently clean its surface.

[0003] The overall floor brush structure of a double-drum vacuum cleaner disclosed in Patent CN218738704U. It consists of a first side plate, a drum, a bracket, a second side plate, left and right pressure plates, universal rollers, and an outer housing. It also includes a pressure plate opening and closing mechanism. Through the opening and closing action of the pressure plate opening and closing mechanism, the left and right pressure plates are locked on the first side plate to form the locking end of the drum, so that the drum is respectively locked in the drum accommodation chamber, or one end of the left and right pressure plates is disengaged from the restraint of the first side plate, and the locking end of the drum is released from the restraint, and the drum can be conveniently taken out from the drum accommodation chamber; the vertical transmission of gears is adopted to simplify the transmission structure between the two drums, making the overall structure of the floor brush compact and concise, with the advantages of simple structure and convenient operation.

[0004] In the above solution, the impurities adhered to the drum may not be completely sucked away when rotating to the adsorption area. Long-term use will surely cause a decrease in the cleaning efficiency of the drum, and the remaining impurities will come to the lower part of the drum with rotation and contact the surface to be cleaned, resulting in secondary pollution.

Detailed Description of the Invention

[0027] The following are specific embodiments of the utility model and in combination with the drawings, the technical solutions of the present utility model will be further described, but the present utility model is not limited to these embodiments.

[0028] As Figures 1 - 4 shown, the double-drum reciprocating swing brush includes a drum 1 and a housing 2. A temporary storage cavity is provided in the housing 2. Two drums 1 at least a part of which are exposed from the bottom of the housing 2 are rotatably arranged in the temporary storage cavity. The two drums 1 are connected by a linkage component 3. A brush cloth 11 is arranged on the outer surface of the drum 1. The two reciprocating and facing brush cloths 11 are in contact with each other in the temporary storage cavity.

[0029] That is, through the transmission of the linkage component 3, the two drums 1 rotate in the same direction and synchronously, so that the brush cloths 11 at the contact parts of the two drums 1 can move towards each other, so that the brush cloths 11 on the two drums 1 can be repeatedly screened against each other in the temporary storage cavity of the housing 2, so that the dust and debris fall into the temporary storage cavity for the vacuum cleaner to suck them away, avoiding the dust and debris remaining on the brush cloth 11 from falling again on the surface to be cleaned after the rotation of the drum 2.

[0030] In this embodiment, a cover plate 12 that fits with the arc surface is provided on the drum 1. A film 13 that is connected to the brush cloth 11 is provided on the outer side of the cover plate 12, and the film 13 reciprocates between the side away from the adjacent drum 1 and the bottom opening of the housing 2.

[0031] The film 13 is used to contact the surface to be cleaned to provide the frictional force for the rotation of the drum 1. The cover plate 12 provided with the film 13 is set to be detachable, considering that it is convenient to replace the film 13 when the frictional force decreases due to adhesion of dust and debris after long-term use.

[0032] Among them, the brush cloths 11 and the films 13 on the two drums 1 are symmetrically arranged, but their starting angles are different. Under the action of the linkage component 3, the two drums 1 rotate in the same direction and synchronously. When the film 13 of one drum 1 contacts the cleaning surface, the brush cloth 11 of the other drum 1 also contacts the cleaning surface. In this way, the rotation of the brush cloth 11 on the other side can be driven by the rolling of the film 13 on one side, so that the two drums 1 alternately drive to perform the cleaning task when pushing the drum brush back and forth.

[0033] Preferably, reinforcing ribs 14 are provided inside the hollow drum 1. A buckle is provided between the reinforcing ribs 14 and the cover plate 12 for detachable connection. A plurality of support protrusions 15 are provided on the inner side of the cover plate 12, and the support protrusions 15 abut against the edge of the cover plate groove on the drum 1.

[0034] The hollow design of the drum 1 can reduce the overall weight of the drum brush and make it easier to operate the drum brush. The reinforcing ribs 14 are provided to enhance the structural strength of the drum, and at the same time, a buckle structure can be provided on the reinforcing ribs 14 to realize the disassembly and assembly function of the cover plate 12.

[0035] The support protrusions 15 provided on the inner side of the cover plate 12 form a plurality of small support platforms to abut against and support the edge of the cover plate groove. Among them, the support protrusions 15 also have a stepped structure that fits with the edge of the cover plate groove to achieve the positioning effect of the cover plate 12 and improve the stability of the film 13 on the outer side of the cover plate 12 after being rubbed.

[0036] In this embodiment, a temporary storage plane 16 is provided on the arc surface of the drum 1. The temporary storage plane 16 is located in the temporary storage cavity and its plane corresponds to the connection part of the brush cloth 11 and the film 13 of the adjacent drum 1.

[0037] The drum 1 rotates reciprocally in a non-full stroke. The arc surface of the drum 1 is axially divided into three parts: a cloth-brushing part 11, a film part 13, and a temporary storage plane 16. Among them, the cloth-brushing part 11 and the film part 13 will contact the surface, while the temporary storage plane 16 is always in the temporary storage cavity inside the housing 2 and does not participate in the contact with the surface.

[0038] When the drum 1 rolls to the end point of the stroke, the temporary storage plane 16 just corresponds to the connection point between the cloth-brushing part 11 and the film part 13 on the adjacent drum 1. At this time, the cloth-brushing part 11 has not yet carried the dust and debris upward into the temporary storage cavity. A gap is left between the temporary storage plane 16 and the adjacent drum 1, enabling the temporary storage cavity connected to the vacuum cleaner to pass through the gap and suck the dust and debris between the two drums 1 without being blocked by the cloth-brushing part 11.

[0039] Preferably, bristles are provided on the cloth-brushing part 11, and the bristles are inclined towards the side of the temporary storage cavity.

[0040] As Figures 5 - 6 shown, the main function of the cloth-brushing part 11 is to carry the dust and debris into the temporary storage cavity. Therefore, the bristles are inclined towards the side of the temporary storage cavity to hold more dust and debris. At the same time, there will still be residual dust and debris on the cloth-brushing part 11 after being sucked by the vacuum cleaner in the temporary storage cavity at the end point of the stroke. Then, the cloth-brushing part 11 starts to move towards the other end point of the stroke, that is, towards the opening at the lower end of the housing 2. At this time, the adjacent cloth-brushing part 11 enters from the opening at the lower end of the housing 2, and the bristles of the two cloth-brushing parts 11 come into contact with each other up and down during the relative movement. Due to the inclined orientation of the bristles, when the upward-moving bristles carry the dust and debris captured on the surface into the temporary storage cavity, they can also sieve the residual dust and debris in the downward-moving bristles onto their own bristles and into the temporary storage cavity. By repeating this cycle, the possibility of residual dust and debris falling out of the temporary storage cavity can be greatly reduced.

[0041] In this embodiment, two roller brush supports 21 are provided inside the housing 2. The drum 1 is mounted between the two roller brush supports 21, and the linkage assembly 3 is arranged on the other side of the roller brush support 21 relative to the drum 1.

[0042] Preferably, roller shaft holes are provided on the roller brush support 21, and roller shafts are provided at the end faces of the drum 1. The roller shafts are rotatably inserted into the roller shaft holes, and the linkage assembly 3 connects the roller shafts of the two drums 1 on the other side of the roller brush support 21.

[0043] The drum 1 is of a hollow structure. Therefore, roller shafts are installed at both axial ends of the drum 1, and two insertion feet are provided on the roller shafts and are inserted into the insertion holes at the end faces of the drum 1.

[0044] Preferably, one pair of roller shaft holes is provided with a margin for horizontal movement towards the other roller shaft hole, and an adjusting spring buckle 22 is provided beside the roller shaft hole. The adjusting spring buckle 22 abuts against the roller shaft.

[0045] As the service life increases, the plastic structure will undergo certain deformation under long-term stress, which will cause the distance between the two rollers 1 to increase. The two brush hairs cannot make full contact, resulting in dust leakage. Therefore, an adjusting spring buckle 22 is provided at the roller hole to continuously apply a thrust to the roller, so that the two rollers 1 can approach each other to improve the effect of the brush hairs alternately carrying dust.

[0046] Preferably, the linkage assembly 3 includes a transmission gear 31 and a roller brush gear 32. The two roller brush gears 32 are arranged on the end faces of the rollers. The transmission gear 31 is rotatably arranged on the roller brush bracket 21 and meshes with the two roller brush gears 32.

[0047] Through the power conduction of the transmission gear 31, the two rollers 1 can rotate synchronously and in the same direction, maintaining the relative starting set angle of the two rollers 1, and can alternately drive and collect dust.

[0048] Preferably, a limiting protrusion 33 is provided on the tooth surface of the roller brush gear 32, and the limiting protrusion 33 abuts against the tooth surface of the transmission gear 31.

[0049] The full-circle rotation of the roller 1 may bring out the residual dust that has not been sucked by the vacuum cleaner from the other side into the temporary storage cavity, allowing the dust to return to the surface to be cleaned again. Therefore, a limiting protrusion 33 is provided on the tooth surface of the roller brush gear 32, and the abutment of the limiting protrusion 33 against the transmission gear 31 is used as the end point of the rotation of the roller 1 to define the reciprocating rotation stroke of the roller 1.

[0050] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
