Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of cleaning equipment and relates to a floor brush component and a cleaning equipment. Background Art
[0002] In daily life, handheld vacuum cleaners can easily cope with various cleaning scenarios because of their small size, portability and flexible operation. The working principle is mainly to generate strong suction through the internal motor, and use the rotation of the roller brush to achieve the cleaning operation of the surface to be cleaned. When the roller brush contacts the surface to be cleaned on the ground, it rotates quickly to roll dust, debris, etc. into the vacuum cleaner, thereby achieving the purpose of cleaning.
[0003] However, in actual use, existing handheld vacuum cleaners also expose some problems. Among them, foreign matter such as hair is easily entangled in the roller brush, which is a more prominent problem. Since hair has a certain degree of flexibility and stickiness, it is easy to be drawn into and entangled in the roller brush during the rotation of the roller brush. Moreover, the foreign matter entangled in the roller brush is not evenly distributed, but is often partially concentrated in a specific part of the roller brush. This not only affects the cleaning effect of the roller brush, but also makes cleaning extremely inconvenient. Utility Model Content

[0037] In the present invention, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are usually in reference to the direction shown in the drawings, or in reference to the vertical, perpendicular or gravitational direction of the component itself; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contour of each component itself, but the above orientation words are not used to limit the present invention. Embodiment
[0038] See Figures 1-5 As shown, a floor brush assembly, the floor brush assembly includes: a base 1, a rotary brush 2 is arranged on the base 1, and the rotary brush 2 is connected to a driving mechanism, so that the rotary brush 2 is rotatably arranged on the base 1. This structure is well known in the prior art and belongs to the known prior art.
[0039] The improvements made in this embodiment on the prior art are as follows:
[0040] A wind collecting cover 3 is arranged on the base 1, the wind collecting cover 3 has a suction port 31, and the suction port 31 is directly opposite to the rotary brush 2. Such a design can ensure that when the rotary brush 2 is performing cleaning work, the generated dust and debris can be effectively sucked into the wind collecting cover 3, improving the cleaning efficiency.
[0041] The floor brush assembly includes a first scraping plate assembly 4 and a second scraping plate 5. The first scraping plate assembly 4 is located outside the suction port 31 and is distributed along the axial direction of the roller brush 2. The second scraping plate 5 is arranged on the base 1 on the side far from the suction port 31. The first scraping plate assembly 4 at least includes a first comb tooth structure 41 and a second comb tooth structure 42. Both the first comb tooth structure 41 and the second comb tooth structure 42 intersect with part of the bristles of the roller brush 2 to process foreign objects (such as hair or lint) on the roller brush 2 from one angle. The second scraping plate 5 is distributed along the axial direction of the roller brush 2 and is provided with a fourth comb tooth structure 51 thereon. The fourth comb tooth structure 51 intersects with part of the bristles of the roller brush 2 to process foreign objects on the roller brush 2 from another angle. The first scraping plate assembly 4 and the second scraping plate 5 cut off foreign objects on the roller brush 2 from both sides respectively, forming an all-round cleaning mode. This design greatly improves the ability to clean the hair and foreign objects wound on the roller brush 2.
[0042] Furthermore, the distance between the tip of the comb teeth of the second comb tooth structure 42 and the roller brush 2 is less than the distance between the tip of the comb teeth of the first comb tooth structure 41 and the roller brush 2. In this way, the depth of insertion of the second comb tooth structure 42 into the roller brush 2 is greater than the depth of insertion of the first comb tooth structure 41 into the roller brush 2, enabling the second comb tooth structure 42 to better cut off the accumulation points of foreign objects wound on the roller brush 2.
[0043] The second comb tooth structure 42 is mainly responsible for processing foreign objects in the middle area of the roller brush 2. During the actual use of the roller brush, the middle area is often one of the places where foreign objects are likely to concentrate. Since the middle part has more frequent and close contact with the surface to be cleaned during the rotation of the roller brush, foreign objects such as hair are more likely to be wound here. The relatively close distance between the tip of the comb teeth of the second comb tooth structure 42 and the roller brush enables it to penetrate into the middle area of the roller brush and effectively cut off the foreign objects wound there.
[0044] In the above floor brush assembly, in addition to the existing first comb tooth structure 41 and second comb tooth structure 42, the first scraping plate assembly 4 is also provided with a third comb tooth structure 43. The third comb tooth structure 43 is used to process foreign objects on the left and right sides of the roller brush.
[0045] During the long-term use of the roller brush, people will find that foreign objects are not only concentrated in the middle area, but foreign objects are also often integrated and wound on the left and right sides of the roller brush. It may be that when cleaning corners or edge areas, foreign objects such as hair will be brought to both sides of the roller brush. The existence of the third comb tooth structure 43 can just solve this problem. It can accurately clean foreign objects on the left and right sides of the roller brush to ensure the overall cleaning effect of the roller brush.
[0046] Specifically, the distance between the comb tooth tip of the third comb tooth structure 43 and the roller brush 2 is smaller than the distance between the comb tooth tip of the first comb tooth structure 41 and the roller brush 2. This means that the third comb tooth structure 43 can get closer to the roller brush 2, thereby playing a more active role in handling foreign matter wrapped around the roller brush.
[0047] Further, the volume of a single comb tooth (third comb tooth 431) in the third comb tooth structure 43 is larger than the volume of a single comb tooth (first comb tooth 411) in the first comb tooth structure 41. This design is of great significance. The third comb tooth 431 with a larger volume can provide a larger contact area and a stronger combing ability. When the roller brush 2 is in operation, some stubborn foreign matter entangled on both sides of the roller brush 2 can be processed by the third comb tooth 431 with a larger volume, so as to improve the cleaning effect of the foreign matter on the roller brush.
[0048] In this embodiment, the distribution position of the third comb tooth structure 43 corresponds to the right side of the roller brush 2. Of course, the third comb tooth structure can also be arranged on the left side to correspond to the left side of the roller brush; or the third comb tooth structure can be arranged on both sides to correspond to the left and right sides of the roller brush.
[0049] In the floor brush assembly of this embodiment, the various structures are ingeniously designed and cooperate with each other, providing a strong guarantee for efficient cleaning.
[0050] Among them, the second comb tooth structure 42 is distributed on the upper edge of the suction port, and is composed of a number of second comb teeth 421 distributed side by side. These second comb teeth 421 are distributed along the axial direction of the roller brush 2, and each second comb tooth 421 extends outward to form a comb tooth tip. There is a gap between two adjacent second comb teeth. This design ensures that each second comb tooth can function independently and form an effective cleaning barrier as a whole. When the roller brush rotates, the second comb tooth structure located on the upper edge of the suction port 31 can quickly deal with foreign matter in the middle area of the roller brush. Due to the particularity of its position, it can intercept and cut off foreign matter before it is sucked into the suction port, thereby improving cleaning efficiency.
[0051] The first comb tooth structure 41 also plays an important role. It is composed of a number of first comb teeth 411 distributed side by side. These first comb teeth 411 are distributed along the axial direction of the roller brush 2, and are distributed on the wind collecting hood 3 and the base 1 on both sides of the suction port 31. When the wind collecting hood 3 is installed on the base 1, the gaps between two adjacent first comb teeth are distributed and the whole is distributed side by side. The outer side surface of each first comb tooth 411 is distributed vertically, and a comb tooth tip is formed at its lower end. This design enables the first comb tooth structure to preliminarily comb out foreign matter on the roller brush, especially for those foreign matter that may enter the areas on both sides of the suction port, which can effectively block and clean them.
[0052] The comb teeth 431 of the third comb tooth structure 43 are arranged side by side with the comb teeth 411 of the first comb tooth structure. This layout further enhances the cleaning ability of the floor brush assembly for foreign objects on the rotating brush. The three comb tooth structures cooperate with each other and perform their respective functions. The first comb tooth structure conducts preliminary combing, the second comb tooth structure focuses on dealing with foreign objects in the middle area, and the third comb tooth structure is responsible for dealing with foreign objects on the left and right sides of the rotating brush. Their combined action ensures that the rotating brush always maintains a good working state during the cleaning process, bringing a more convenient and efficient cleaning experience to users.
[0053] In this embodiment, the third comb tooth structure 43 and part of the first comb tooth structure are integrally formed with the base 1, which can improve the overall stability and durability. When using the floor brush for cleaning, the integrally formed structure can better withstand the acting force brought by the rotation of the rotating brush, ensuring that the third comb tooth structure and the corresponding first comb tooth structure can always remain in the correct position and effectively deal with foreign objects on the left and right sides of the rotating brush. At the same time, the second comb tooth structure 42 and another part of the first comb tooth structure are integrally formed with the air collecting cover 3, which also provides a strong guarantee for the cleaning function of the floor brush. When the air collecting cover is working, the integrally formed comb tooth structure can more accurately deal with foreign objects in the middle area of the rotating brush, improve the cleaning efficiency, and bring a more convenient and efficient cleaning experience to users.
[0054] In this embodiment, the air collecting cover 3 of the floor brush assembly adopts a horn-shaped structure design, which can effectively guide the airflow and enhance the suction force. The air collecting cover 3 is centrally arranged on the base 1, making the entire floor brush assembly more coordinated in appearance and ensuring that the suction force can act evenly on the rotating brush 2 during the cleaning process. The main body of the air collecting cover 3 is locked to the base 1 by bolts. This connection method is firm and reliable, can withstand a large external force, and ensures that the air collecting cover will not loosen easily during use. In addition, both sides of the front end of the air collecting cover 3 are fixed to the base 1 by snap connection, further enhancing the stability of the air collecting cover. Such a design can not only stabilize the position of the first comb tooth structure on the air collecting cover 3, enabling it to better play the role of combing and cutting foreign objects, but also improve the durability of the entire floor brush assembly, bringing a more efficient and stable cleaning experience to users.
[0055] In this embodiment, the fourth comb structure provided on the second squeegee of the floor brush assembly has a unique design. There are three groups of combs on the fourth comb structure, namely combs 511, 512, and 513. The distribution of these three groups of combs is very ingenious and corresponds to the left, middle, and right positions of the roller brush respectively. When the roller brush is working, no matter which position the foreign object is wound around the roller brush, there will be a corresponding comb for targeted treatment. For the position on the left side of the roller brush, comb 511 can clean the foreign object wound here in time; the foreign object in the middle position is handled by comb 512; and the foreign object on the right side of the roller brush will be effectively cut and cleaned by comb 513. This design greatly improves the cleaning ability of the floor brush assembly for foreign objects in different positions on the roller brush, ensures that the roller brush always maintains a good working state during the cleaning process, and brings a more efficient and comprehensive cleaning experience to the user.
[0056] Furthermore, the structures of combs 511, 512, and 513 are the same. The combs 511, 512, and 513 may have multiple comb teeth; the arrangement direction of the multiple comb teeth is parallel to the axis direction of the roller brush 2.
[0057] The present utility model also proposes a cleaning device, and the cleaning device includes the above floor brush assembly.
[0058] According to the cleaning device of the present utility model, when cleaning the surface to be cleaned, the roller brush 2 of the floor brush assembly rotates, so as to use the roller brush 2 to remove the dirt on the surface to be cleaned. During the rotation of the roller brush 2, the first squeegee assembly 4 and the second squeegee 5 respectively clean the foreign objects on the roller brush 2 from two different directions in an all-round way. At the same time, for the middle and both sides of the roller brush 2 where foreign objects are likely to accumulate, specific comb teeth are provided on the first squeegee assembly 4 and the second squeegee 5 for targeted cutting and cleaning, so as to improve the overall cleaning effect.
