实施例1Example 1
本实施例提供一种滚刷,用于与待清洁表面接触,请参见图1,该滚刷包括滚刷体1、弹性件2及清洁件5。该弹性件2包覆于滚刷体1的外圆周面上并沿滚刷体1的轴线方向延伸,弹性件2内形成有空腔3。清洁件5至少部分包覆于弹性件2的外圆周面上。当滚刷受外力作用时,弹性件2于受力方向发生形变,以调节清洁件5与待清洁表面的接触面积。需要说明的是,该空腔3内可填充有填充物,具体如气体、液体、气体与液体的混合物或具有弹性的材料等,以提高滚刷的强度。在本实施例中,该腔体3内的填充物为标准大气压下的空气、氦气、氮气等。在其他实施例中,该腔体3内还可以填充冷却液,以对滚刷高速转动时产生的高温进行冷却。在其他实施例中,该腔体3还可以填充固体支撑物,如橡胶支柱,用来避免弹性件2的过度形变。This embodiment provides a roller brush for contacting the surface to be cleaned. Please refer to FIG. 1 . The roller brush includes a roller brush body 1 , an elastic member 2 and a cleaning member 5 . The elastic member 2 covers the outer circumferential surface of the brush roller body 1 and extends along the axial direction of the brush roller body 1. A cavity 3 is formed in the elastic member 2. The cleaning member 5 at least partially covers the outer circumferential surface of the elastic member 2 . When the roller brush is acted upon by an external force, the elastic member 2 deforms in the direction of the force to adjust the contact area between the cleaning member 5 and the surface to be cleaned. It should be noted that the cavity 3 can be filled with filler, such as gas, liquid, a mixture of gas and liquid, or elastic material, to improve the strength of the roller brush. In this embodiment, the filling material in the cavity 3 is air, helium, nitrogen, etc. under standard atmospheric pressure. In other embodiments, the cavity 3 can also be filled with cooling liquid to cool the high temperature generated when the roller brush rotates at high speed. In other embodiments, the cavity 3 can also be filled with solid supports, such as rubber pillars, to avoid excessive deformation of the elastic member 2 .
滚刷体1及清洁件5采用现有技术。为了在使用时滚动方便,滚刷体1设置为柱体。本实施例中,为节约成本并减轻重量,滚刷体1包括中空的圆柱体以及嵌设在该圆柱体两端的端部上的端盖(未标号)。在其他实施例中,滚刷体1也可以是内部为实心或者仅在左右两端开设端口的柱体,可结合设计需求进行调整。在本实施例中,清洁件5采用可以起到清洁作用的绒布,于其他实施例中,清洁件5可以是其它对待清洁表面有清洁作用的部件,如毛刷、毛条、皮条等。清洁件5可以采用胶黏或者魔术贴等方式套设在弹性件2的外侧,将清洁件5包裹在柱体上为现有技术,在此处不详细描述。The roller brush body 1 and the cleaning parts 5 adopt existing technology. In order to facilitate rolling during use, the roller brush body 1 is configured as a cylinder. In this embodiment, in order to save costs and reduce weight, the brush body 1 includes a hollow cylinder and end caps (not numbered) embedded on both ends of the cylinder. In other embodiments, the roller brush body 1 can also be a cylinder with a solid interior or only opening ports at the left and right ends, which can be adjusted according to design requirements. In this embodiment, the cleaning member 5 is a flannel cloth that can perform a cleaning function. In other embodiments, the cleaning member 5 can be other components that have a cleaning function on the surface to be cleaned, such as brushes, tops, leather strips, etc. The cleaning element 5 can be set on the outside of the elastic element 2 by means of glue or Velcro. Wrapping the cleaning element 5 on the cylinder is an existing technology and will not be described in detail here.
在使用时,当滚刷于待清洁表面进行清洁工作,由于滚刷的自重力作用,以使滚刷受到待清洁表面对其的支撑力,同时,当滚刷转动以于待清洁表面移动时,还会受到待清洁表面对其产生的摩擦力,使得滚刷上的弹性件2于待清洁表面对滚刷的支撑力以及摩擦力的作用方向发生形变,以使滚刷与待清洁表面之间的接触从线性接触转为面性接触,从而增大了滚刷与待清洁表面之间的接触面积,即增加了擦洗面积,以提升滚刷的清洁效率。When in use, when the roller brush is cleaning the surface to be cleaned, due to the gravity of the roller brush, the roller brush is supported by the surface to be cleaned. At the same time, when the roller brush rotates to move on the surface to be cleaned, , it will also be subject to the friction force generated by the surface to be cleaned, causing the elastic member 2 on the roller brush to deform in the direction of the support force of the surface to be cleaned on the roller brush and the friction force, so that the relationship between the roller brush and the surface to be cleaned is The contact between the roller brushes changes from linear contact to surface contact, thereby increasing the contact area between the roller brush and the surface to be cleaned, that is, increasing the scrubbing area to improve the cleaning efficiency of the roller brush.
与现有技术相比,由于现有技术中的滚刷衬底为硬性材质,当滚刷于待清洁表面进行清洁工作时,仅依靠清洁件自身的形变以贴合待清洁表面,
在使用时,当滚刷在不同材质或高度的待清洁表面之间过渡时,如从硬质地面过渡到地毯表面,或者经过台阶,因滚刷的形变量不足,容易造成滚刷跳起,从而使滚刷堵转。而本实施例中的滚刷上设置有具有空腔3的弹性件2,提高了滚刷的形变量,使得本实施例中的滚刷在不同的高度或材质的待清洁表面之间过渡时,不会于受力方向弹起,从而避免滚刷堵转,使得滚刷在不同高度或材质的待清洁表面之间的过渡过程更加顺滑。Compared with the prior art, since the roller brush substrate in the prior art is made of hard material, when the roller brush is cleaning the surface to be cleaned, it only relies on the deformation of the cleaning piece itself to fit the surface to be cleaned. When in use, when the roller brush transitions between surfaces to be cleaned of different materials or heights, such as transitioning from a hard floor to a carpet surface, or passing through steps, the roller brush may easily jump due to insufficient deformation. This causes the roller brush to block. The roller brush in this embodiment is provided with an elastic member 2 with a cavity 3, which increases the deformation amount of the roller brush, so that the roller brush in this embodiment transitions between surfaces to be cleaned of different heights or materials. , will not bounce up in the direction of force, thereby preventing the roller brush from blocking, making the transition process between the roller brush and the surfaces to be cleaned of different heights or materials smoother.
在本实施例中,该弹性件2的端面略突伸出于清洁件的端面,且弹性件2的两端的端部上沿其径向方向形成有凸起(未标号),该凸起紧贴在清洁件5的端面上,以将该清洁件5固定在弹性件2两端的凸起内,以限制该清洁件5相对于弹性件2沿弹性件2的轴线方向移动,使得弹性件2、滚刷体1以及清洁件5在装配完成后的结构更加稳固,以避免清洁件5在受外力作用下于弹性件2上脱离,影响滚刷的使用。在其他实施例中,也可将弹性件2、滚刷体1以及清洁件5的端面设置在同一面上,以避免滚刷在使用时,毛发、灰尘等进入弹性件2、滚刷体1以及清洁件5端面的夹缝处,对待清洁面产生二次污染,提高清洁效率。弹性件2、滚刷体1及清洁件5的具体布置结构可结合设计需求进行选择和调整,在此不一一举例。In this embodiment, the end surface of the elastic member 2 slightly protrudes from the end surface of the cleaning member, and protrusions (not numbered) are formed on both ends of the elastic member 2 along its radial direction. The protrusions are tightly Attached to the end surface of the cleaning member 5 to fix the cleaning member 5 in the protrusions at both ends of the elastic member 2 to limit the movement of the cleaning member 5 relative to the elastic member 2 along the axis direction of the elastic member 2, so that the elastic member 2 , the structure of the roller brush body 1 and the cleaning part 5 is more stable after the assembly is completed, so as to prevent the cleaning part 5 from detaching from the elastic member 2 under the action of external force, affecting the use of the roller brush. In other embodiments, the end surfaces of the elastic member 2 , the roller brush body 1 and the cleaning member 5 can also be arranged on the same surface to prevent hair, dust, etc. from entering the elastic member 2 and the roller brush body 1 when the roller brush is in use. And the gap between the end faces of the cleaning parts 5 produces secondary pollution on the surface to be cleaned, thereby improving cleaning efficiency. The specific arrangement structure of the elastic member 2, the roller brush body 1 and the cleaning member 5 can be selected and adjusted according to the design requirements, and no examples are given here.
实施例2Example 2
本实施例提供一种滚刷,请参见图3,该滚刷为安装在洗地机上用于清洗地面或者地毯的滚刷,当然,在其他实施例中,该滚刷也可以安装在其他设备上或者用于清洁其他待清洁面。下面以安装在洗地机上用于清洗地面或者地毯的滚刷为例进行说明。This embodiment provides a roller brush. Please refer to Figure 3. The roller brush is a roller brush installed on a floor washing machine for cleaning floors or carpets. Of course, in other embodiments, the roller brush can also be installed on other equipment. or used to clean other surfaces to be cleaned. The following is an example of a roller brush installed on a floor washing machine for cleaning floors or carpets.
本实施例中,该滚刷与实施例1的滚刷结构相似,区别在于:空腔3的数量为若干个,于圆周方向上设置的相邻两个空腔3之间设置有辐条筋4。通过在滚刷的空腔3内设置若干辐条筋4以将弹性件2内具有若干个空腔3,以加强滚刷的结构强度。当弹性件2的任意一个或者多个空腔3在外力作用下损坏时,弹性件2依旧可以支撑滚刷于受力方向发生形变,增加了滚刷的使用寿命,降低成本。In this embodiment, the structure of the roller brush is similar to that of the roller brush in Embodiment 1. The difference is that the number of cavities 3 is several, and spoke ribs 4 are provided between two adjacent cavities 3 in the circumferential direction. . By arranging several spoke ribs 4 in the cavity 3 of the roller brush, the elastic member 2 has several cavities 3 to enhance the structural strength of the roller brush. When any one or more cavities 3 of the elastic member 2 are damaged under the action of external force, the elastic member 2 can still support the roller brush to deform in the direction of force, which increases the service life of the roller brush and reduces the cost.
在本实施例中,辐条筋4自靠近滚刷体1的一端朝远离滚刷体1的一端沿第一方向延伸,第一方向的延伸线与滚刷体1形成至少为10°的锐角的夹
角,第一方向与滚刷的转动方向相反。当滚刷于地面进行清洁工作时,滚刷具有向下的自重力,相应的会受到地面对其向上的支撑力,同时滚刷相对地面转动,与地面之间会产生方向相反的摩擦力。由于辐条筋4的延伸方向的延伸线与滚刷体1形成的夹角为至少为10°的锐角,即若干辐条筋4于弹性件2内均为斜向设置,以使弹性件2内的若干空腔3于圆周方向上沿与滚刷的运动方向相反的方向延伸,以使空腔3与辐条筋4具有朝向滚刷运动方向形变的趋势,当滚刷转动时,滚刷与地面接触部位对应的空腔3与辐条筋4受力更容易发生形变,从而增大弹性件2的形变程度,提高滚刷的形变量。同时,当滚刷于地面进行清洁工作时,由于辐条筋4的延伸方向与滚刷的转动方向相反,使得滚刷出现逆转倾向时,会受到辐条筋4对其的阻力,以避免其逆转,从而提高滚刷的使用安全性。In this embodiment, the spoke ribs 4 extend in a first direction from an end close to the brush roller body 1 to an end far away from the brush roller body 1 , and the extension line in the first direction forms an acute angle of at least 10° with the brush roller body 1 . folder Angle, the first direction is opposite to the rotation direction of the roller brush. When the roller brush is cleaning the ground, the roller brush has downward self-gravity, and accordingly it will be supported upward by the ground. At the same time, the roller brush rotates relative to the ground, and there will be friction in the opposite direction with the ground. . Since the angle formed by the extension line of the extending direction of the spoke ribs 4 and the roller brush body 1 is an acute angle of at least 10°, that is, several spoke ribs 4 are arranged obliquely in the elastic member 2, so that the elastic members 2 A number of cavities 3 extend in the circumferential direction opposite to the direction of movement of the roller brush, so that the cavities 3 and the spoke ribs 4 have a tendency to deform in the direction of movement of the roller brush. When the roller brush rotates, the roller brush contacts the ground. The corresponding cavity 3 and spoke rib 4 are more likely to deform under stress, thereby increasing the deformation degree of the elastic member 2 and increasing the deformation amount of the roller brush. At the same time, when the roller brush is cleaning the ground, since the extension direction of the spoke ribs 4 is opposite to the rotation direction of the roller brush, when the roller brush tends to reverse, it will be resisted by the spoke ribs 4 to avoid its reversal. Thereby improving the safety of using the roller brush.
在另一可选的实施方案中,请参见图4,辐条筋4自靠近滚刷体1的一端朝远离滚刷体1的一端沿第一方向延伸并相切于滚刷体1,第一方向与滚刷的转动方向相反。将辐条筋4设置为与滚刷体1相切,以提高地面对滚刷的支撑力与摩擦力可作用于辐条筋4及空腔3并使辐条筋4与空腔3形变的力的大小及,增加弹性件2的形变程度,从而提高滚刷的形变量。同时,辐条筋4的延伸方向与滚刷的转动方向相反,可避免滚刷逆转。In another optional embodiment, please refer to Figure 4, the spoke ribs 4 extend in the first direction from the end close to the roller brush body 1 to the end far away from the roller brush body 1 and are tangent to the roller brush body 1. The first The direction is opposite to the rotation direction of the roller brush. The spoke ribs 4 are set to be tangent to the roller brush body 1, so as to increase the support force and friction force of the ground against the roller brush, which can act on the spoke ribs 4 and the cavity 3 and deform the spoke ribs 4 and the cavity 3. The size increases the deformation degree of the elastic member 2, thereby increasing the deformation amount of the roller brush. At the same time, the extension direction of the spoke ribs 4 is opposite to the rotation direction of the roller brush, which can prevent the roller brush from reversing.
在又一可选的实施方案中,请参见图5,辐条筋4自靠近滚刷体1的一端朝远离滚刷体1的一端沿第一方向弯曲并呈弧形,第一方向与滚刷的转动方向相反。将辐条筋4设置为弧形结构,弧形结构受力后更容易发生形变,以使滚刷作用于硬度较低的待清洁面时,如地毯等,也可以提高弹性件2的形变程度,从而提高滚刷的形变量。同时,辐条筋4的弯曲方向与滚刷的转动方向相反,可避免滚刷逆转。In yet another optional embodiment, please refer to Figure 5. The spoke ribs 4 are bent in a first direction and in an arc shape from the end close to the roller brush body 1 to the end far away from the roller brush body 1. The first direction is in line with the roller brush body 1. The direction of rotation is opposite. The spoke ribs 4 are arranged in an arc-shaped structure. The arc-shaped structure is more likely to deform after being stressed, so that when the roller brush acts on the surface to be cleaned with low hardness, such as carpets, the degree of deformation of the elastic member 2 can also be increased. Thereby increasing the deformation amount of the roller brush. At the same time, the bending direction of the spoke ribs 4 is opposite to the rotation direction of the roller brush, which can prevent the roller brush from reversing.
需要说明的是,上述三个实施方案的辐条筋4的结构可以单独设置或者任意两两组合或者三个组合在一起,具体可根据设计需求进行选择,在此不做具体限定。It should be noted that the structures of the spoke ribs 4 in the above three embodiments can be set individually or combined in any two or three combinations. The specific selection can be made according to the design requirements and is not specifically limited here.
在本实施例中,弹性件2和若干辐条筋4一体集成。且若干辐条筋4等间距设置。通过一体集成设置使得弹性件2和若干辐条筋4的结构更加稳固,可以通过生产线统一加工,以提高生产效率。若干辐条筋4等间距设置以使
得若干辐条筋4将弹性件2内的空腔3分隔成大小相同的若干个,使得弹性件2在各个位置的受力均匀,从而使滚刷作用于地面时更加平稳,清洁效果更好。在其他实施例中,弹性件2和若干辐条筋4也可分开设置,通过固定件或者胶水粘黏固定在一起。若干辐条筋4间的间距也可设置为任意距离,具体结合实际需求进行调整,在此不做详细赘述。In this embodiment, the elastic member 2 and several spoke ribs 4 are integrally integrated. And several spoke ribs 4 are arranged at equal intervals. The integrated arrangement makes the structure of the elastic member 2 and several spoke ribs 4 more stable, and can be processed uniformly through the production line to improve production efficiency. A number of spoke ribs 4 are arranged at equal intervals so that A plurality of spoke ribs 4 are obtained to divide the cavity 3 in the elastic member 2 into several ones of the same size, so that the elastic member 2 is evenly stressed at various positions, thereby making the roller brush more stable when acting on the ground, and the cleaning effect is better. In other embodiments, the elastic member 2 and the plurality of spoke ribs 4 can also be arranged separately and fixed together through fasteners or glue. The spacing between several spoke ribs 4 can also be set to any distance, which can be adjusted based on actual needs and will not be described in detail here.
实施例3Example 3
本实施例提供一种清洁设备,该清洁设备包括机体和滚刷,滚刷安装在机体上。其中,滚刷是前述两个实施例中的任意一种,具体可参见前述实施例。该清洁设备可以是吸尘器或者扫地机器人等,具体的连接方式及结构特征本领域的技术人员可以根据实际情况做调整,在此不一一举例。在实际应用中,滚刷的尺寸及安装位置可以结合清洁设备的尺寸及类型进行调整。当滚刷作用于待清洁面时,会受到待清洁面对其的支撑力与摩擦力,以使该滚刷于受力方向发生形变,从而使滚刷于待清洁面从线性接触变为面性接触,增大了滚刷与待清洁表面之间的接触面积,即增加了擦洗面积,以提升清洁设备的清洁效率。This embodiment provides a cleaning device. The cleaning device includes a machine body and a roller brush. The roller brush is installed on the machine body. Wherein, the roller brush is any one of the two aforementioned embodiments. For details, please refer to the aforementioned embodiments. The cleaning equipment may be a vacuum cleaner or a sweeping robot, etc. The specific connection method and structural features can be adjusted by those skilled in the art according to the actual situation, and examples are not given here. In practical applications, the size and installation position of the roller brush can be adjusted based on the size and type of cleaning equipment. When the roller brush acts on the surface to be cleaned, it will receive the support and friction force of the surface to be cleaned, so that the roller brush deforms in the direction of the force, so that the roller brush changes from linear contact to surface contact with the surface to be cleaned. Sexual contact increases the contact area between the roller brush and the surface to be cleaned, that is, the scrubbing area is increased to improve the cleaning efficiency of the cleaning equipment.
在本实施例中,该清洁设备还包括抵压在滚刷上的刮水条。具体的于清洁设备的前进方向上,刮水条的投影在滚刷体的最低端与中心轴之间。将刮水条的位置设置在滚刷体的最低端与中心轴之间,以使得刮水条的刮水效果最好,避免因设置的过高,导致刮水不充分,或者设置的过低,以使弹性件损坏时,刮水条会直接剐蹭地面,从而破坏刮水条或损坏清洁设备。以此可以提高清洁设备的使用安全性和使用寿命。另外,由于带有空腔的弹性件的形变程度大,当刮水条在刮水时,滚刷受到刮水条的挤刮力作用,并沿该挤刮力的作用方向发生形变,避免刮水条对滚刷上的清洁件进行硬性挤刮,从而破坏清洁件,以提高滚刷的使用寿命,并提高清洁设备的清洁效率。In this embodiment, the cleaning device further includes a wiper strip pressed against the roller brush. Specifically, in the forward direction of the cleaning equipment, the projection of the wiper strip is between the lowest end of the brush body and the central axis. Set the position of the wiper strip between the lowest end of the roller brush body and the central axis so that the wiper strip has the best wiping effect and avoids insufficient wiping caused by setting it too high or setting it too low. , so that when the elastic part is damaged, the wiper strip will scratch the ground directly, thereby damaging the wiper strip or damaging the cleaning equipment. This can improve the safety and service life of cleaning equipment. In addition, due to the large degree of deformation of the elastic member with the cavity, when the wiper strip is wiping, the roller brush is affected by the squeezing and scraping force of the wiper strip, and deforms along the direction of the squeezing and scraping force to avoid scraping. The water strips squeeze and scrape the cleaning parts on the roller brush hard, thereby destroying the cleaning parts, thereby increasing the service life of the roller brush and improving the cleaning efficiency of the cleaning equipment.
综上所述,本申请通过在滚刷上设置带有空腔3的弹性件2,当滚刷在自重力作用,受到待清洁表面对其向上的支撑力,弹性件2受该支撑力作用并沿该支撑力的作用方向发生形变,以使滚刷与待清洁表面之间的接触从线性接触转为面性接触,从而增大了滚刷与待清洁表面的接触面积,即增
加了擦洗面积。带有空腔3的弹性件2的滚刷在不同的高度或材质的待清洁表面之间过渡时,不会于受力方向弹起,从而发生堵转,使得滚刷在不同高度或材质的待清洁表面之间的过渡过程更加顺滑。另外,将具有该种结构的滚刷应用于清洁设备上,可以提高清洁设备的清洁效率以及使用安全性。To sum up, this application provides an elastic member 2 with a cavity 3 on the roller brush. When the roller brush acts under its own gravity, it receives an upward support force from the surface to be cleaned, and the elastic member 2 is acted upon by this support force. And deformation occurs along the direction of the supporting force, so that the contact between the roller brush and the surface to be cleaned changes from linear contact to surface contact, thereby increasing the contact area between the roller brush and the surface to be cleaned, that is, increasing the contact area between the roller brush and the surface to be cleaned. Added scrubbing area. When the roller brush of the elastic member 2 with the cavity 3 transitions between surfaces to be cleaned of different heights or materials, it will not bounce up in the direction of force, thus blocking the rotor, causing the roller brush to move between surfaces of different heights or materials. Transitions between surfaces to be cleaned are smoother. In addition, applying the roller brush with this structure to cleaning equipment can improve the cleaning efficiency and safety of use of the cleaning equipment.
显然,上述所描述的实施例仅仅是本申请一部分的实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有做出创造性劳动前提下,可以做出其它不同形式的变化或变动,都应当属于本申请保护的范围。
