Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a floor brush mechanism and cleaning equipment. Background Technology

[0002] The floor brush mechanism of a vacuum cleaner includes a housing and a rotating roller brush mounted on it. Dust easily accumulates on the roller brush, preventing the vacuum cleaner from achieving a good cleaning effect. To solve this problem, existing cleaning devices also include a comb mounted on the housing, with the ends of the comb extending into the roller brush to remove dust from the brush, thus enabling the vacuum cleaner to achieve a better cleaning effect.

[0003] However, existing combs cannot effectively clean the hair on the roller brush; they can only comb the hair. The cleaning ability of a roller brush covered in hair is greatly reduced. Furthermore, even after combing, long hair, due to its length, is sucked into the air intake at one end and gets tangled in the roller brush at the other. The high adhesion to the roller brush causes the hair to coil, resulting in missing or shortened bristles and significantly reducing the brush's cleaning ability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a floor brush mechanism and cleaning device that can effectively cut hair on the floor brush mechanism and improve the cleaning ability of the floor brush mechanism and cleaning device.

[0005] This utility model is achieved through the following technical solution:

[0006] A floor brush mechanism includes a housing, a roller brush, comb teeth, and a blade. The roller brush is pivotally connected to the housing about the axis of the roller brush. One side of the comb teeth is connected to the housing, and the other side extends at least partially into the roller brush. The housing is provided with an air intake. The roller brush and the comb teeth are both located at the front end of the air intake. In the direction of the roller brush axis, the first end of the comb teeth is closer to the axis of the roller brush than the second end of the blade. The blade is capable of cutting the hair on the roller brush.

[0007] Furthermore, the blade is integrally formed with the comb teeth.

[0008] Furthermore, the point perpendicular from the rotation center of the roller brush to the direction of the blade tip is closer to the air intake than the axis of the roller brush, so as to facilitate the intake of the cut hair.

[0009] Furthermore, the comb teeth include a main body and a plurality of combing portions protruding from the main body, with gaps formed between adjacent combing portions, and the blades are at least partially located within the gaps.

[0010] Furthermore, the combing section has a "V" shaped structure, and the tip of the combing section is positioned away from the main body.

[0011] Furthermore, the plurality of combing sections are evenly spaced and arranged in a direction parallel to the axis of the roller brush.

[0012] Furthermore, the axial direction of the blade is parallel to the arrangement direction of the plurality of combing sections.

[0013] Furthermore, the combing section is formed by extending obliquely downward from the main body and toward the roller brush, and the combing section is disposed perpendicular to the main body.

[0014] Furthermore, the side of the main body that is opposite to the combing part is integrally formed with the shell.

[0015] Furthermore, both sides of the combing section are formed with arc-shaped surfaces, and the arc-shaped surfaces include a first arc-shaped surface and a second arc-shaped surface that are symmetrically arranged about the axis of the combing section.

[0016] Furthermore, straight sections are formed on both sides of the combing section. The straight sections include a first straight section and a second straight section symmetrically arranged about the axis of the combing section, and adjacent first straight sections and second straight sections form the gap.

[0017] Furthermore, a plurality of reinforcing ribs are provided between the comb teeth and the housing, and the reinforcing ribs are provided one-to-one with the plurality of combing parts.

[0018] Furthermore, the reinforcing rib is connected to the main body, the combing part, and the shell.

[0019] Furthermore, the reinforcing rib is located on the side of the comb teeth away from the roller brush, and the reinforcing rib is perpendicular to the main body.

[0020] Furthermore, the blade includes a blade body extending perpendicular to the axis of the roller brush and a blade, with protrusions on both sides of the blade body.

[0021] A cleaning device including the aforementioned floor brush mechanism.

[0022] Compared with existing technologies, the advantages of this utility model are:

[0023] 1. By incorporating blades on the comb teeth, when the roller brush has a large amount of hair, the blades cut the hair after it is combed by the comb teeth. The shorter hair is less likely to entangle on the roller brush, ensuring its cleanliness and improving the cleaning ability of the floor brush mechanism and cleaning device. Furthermore, the shorter hair prevents it from getting tangled on the roller brush, avoiding localized missing or shortened bristles, effectively improving the brush's cleaning power. The shorter hair then smoothly enters the cyclone separator through the air intake, preventing it from tangling with the cyclone separator filter and ensuring its optimal filtration effect.

[0024] 2. By integrating the blade and comb teeth into one piece, the assembly process of the floor brush mechanism can be simplified. On the other hand, when the blade and comb teeth are designed separately, hair or dust on the roller brush can easily enter and accumulate in the gap between the blade and comb teeth. Users need to disassemble the blade regularly to clean the dust or hair in the gap, which increases the user's burden. However, by integrating the blade and comb teeth into one piece, there is no gap between the blade and comb teeth, which fundamentally solves the problem of hair or dust accumulation and reduces the user's burden.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0036] like Figures 1-5 As shown, a cleaning device according to an embodiment of the present invention will now be described using a vacuum cleaner as an example. The vacuum cleaner provided in this embodiment includes a floor brush mechanism and a body mechanism. The floor brush mechanism is located below the body mechanism. The body mechanism includes a connecting rod and a dust collection device. The connecting rod is connected to the floor brush mechanism. The operator can move the position of the floor brush mechanism by pushing the connecting rod. The dust collection device is located on the connecting rod and is connected to the floor brush mechanism through the connecting rod. The dust collection device achieves the filtering effect of dust and debris.

[0037] like Figure 1 As shown, the floor brush mechanism includes a housing 1 and a roller brush 2. The roller brush 2 is pivotally connected to the housing 1 around the axis of the roller brush 2. The housing 1 is provided with an air intake 10. The roller brush 2 is located at the front end of the air intake 10. The roller brush 2 rotates relative to the housing 1 to roll up the dust on the ground. A negative pressure is formed at the air intake 10 to suck in the dust, thereby realizing the cleaning function of the vacuum cleaner on the ground.

[0038] like Figure 3 and Figure 9As shown, the floor brush mechanism also includes comb teeth 3 and blades 4. The comb teeth 3 are located at the front end of the air intake 10, and one side of the comb teeth 3 is connected to the housing 1, while the other side extends at least partially into the roller brush 2. The comb teeth 3 can comb the hair on the roller brush 2. The blades 4 are integrally formed with the comb teeth 3 and can cut the hair. By designing the blades 4 and comb teeth 3 as an integral unit, the assembly process of the floor brush mechanism is simplified. On the other hand, when the blades 4 and comb teeth 3 are separate, hair or dust on the roller brush 2 can easily enter and accumulate in the gap between the blades 4 and comb teeth 3. Users need to regularly disassemble the blades 4 to clean the dust or hair in the gap, thus increasing the user's burden. However, by designing the blades 4 and comb teeth 3 as an integral unit, there is no gap between the blades 4 and comb teeth 3, fundamentally solving the problem of hair or dust accumulation and reducing the user's burden. Reference Figure 6 It is worth noting that, in the axial direction of the roller brush 2, the first end 33 of the comb tooth 3 is closer to the axis of the roller brush 2 than the second end 40 of the blade 4, ensuring that the bristles contact the comb tooth 3 first, and the comb tooth 3 deforms it to prevent the bristles from being cut by the blade 4.

[0039] like Figure 7 As shown, the point 6 perpendicular from the rotation center of the roller brush 2 to the blade 4 in the direction of the blade head is closer to the air inlet 10 than the axis of the roller brush 2, so that the cut hair can be sucked in.

[0040] like Figure 3 As shown, specifically, the comb 3 includes a main body 30 and a plurality of combing parts 31 protruding from the main body 30. A gap 32 is formed between adjacent combing parts 31, and the blade 4 is at least partially located within the gap 32. When there is a lot of hair on the roller brush 2, the hair is slowly pushed from the free end of the combing part 31 to the gap 32 between adjacent combing parts 31. When the hair is pushed to the blade 4, the blade 4 can cut the hair. The shortened hair is less likely to get tangled on the roller brush 2, ensuring the cleanliness of the roller brush 2 and improving the cleaning ability of the floor brush mechanism.

[0041] The combing section 31 has a "V" shaped structure, and the tip 310 of the combing section 31 is located away from the main body 30. The tip 310 here is also the first end 33 of the comb teeth 3. By designing the combing section 31 into a V-shaped structure, the hair can be better gathered onto the blade 4 for cutting. The design of the tip 310 of the combing section 31 makes it easier for the free end of the combing section 31 to extend into the roller brush 2 and more easily separate the tangled hair. Furthermore, the separated hair is pushed along both sides of the combing section 31 to the gap 32 between adjacent combing sections 31.

[0042] like Figure 5As shown, both sides of the combing section 31 have arc-shaped surfaces 311, which include a first arc surface 312 and a second arc surface 313 symmetrically arranged about the axis of the combing section 31. By designing the two sides of the combing section 31 with an arc-shaped structure, the resistance of the combing section 31 to the hair is further reduced, and the separated hair can move more smoothly from the free end of the combing section 31 to the gap 32 between adjacent combing sections 31.

[0043] like Figure 9 As shown, straight sections 314 are formed on both sides of the combing section 31. The straight sections 314 include a first straight section 315 and a second straight section 316 symmetrically arranged about the axis of the combing section 31. The adjacent first straight section 315 and second straight section 316 form a gap 32, which allows the blade 4 located in the gap 32 to be exposed over a larger area, and at the same time improves the stability of the blade 4.

[0044] In addition, since the comb teeth 3 and the blades 4 are both located at the front end of the air inlet 10, the cut hair is sucked into the dust storage device of the cleaning device by the negative pressure at the air inlet 10, which can effectively prevent the cut hair from being rolled back into the roller brush 2 and effectively improve the cleanliness of the roller brush 2.

[0045] Furthermore, the shorter hairs will not get tangled on the roller brush 2, preventing localized loss or shortening of the bristles and effectively improving the cleaning power of the roller brush 2. In addition, the shorter hairs smoothly enter the cyclone separator through the air intake 2, preventing them from tangling with the cyclone separator filter and ensuring a better filtration effect.

[0046] In this embodiment, multiple combing sections 31 are evenly spaced and arranged in a direction parallel to the axis of the roller brush 2. In other embodiments, due to space limitations, such as to avoid the air intake 10, the multiple combing sections 31 cannot be arranged in a straight line to make full use of the local space. In these embodiments, the multiple combing sections 31 are arranged along curves, along broken lines, or staggered in a direction parallel to the axis of the roller brush 2.

[0047] In this embodiment, the axial direction of the blade 4 is parallel to the arrangement direction of the multiple combing sections 31. The hair is slowly pushed from the free end of the combing section 31 to the gap 32 between adjacent combing sections 31. When the hair is pushed to the blade 4, the blade 4 can cut the hair immediately.

[0048] The combing section 31 is formed by extending obliquely downward from the main body 30 toward the roller brush 2, and the combing section 31 is set perpendicular to the main body 30.

[0049] The main body 30 is integrally formed with the housing 1 on the side opposite to the combing part 31. During assembly, it is sufficient to ensure that the housing 1 is installed in place, without the need to install the comb teeth 3 separately, which simplifies the installation steps.

[0050] like Figure 8 As shown, the housing 1 includes a viewing window with comb teeth 3 on it. The blade 4 includes a blade body 42 extending perpendicular to the axis of the roller brush 2 and a blade 4. Protrusions 41 are provided on both sides of the blade body 42. The protrusions 41 can position the blade 4 as an insert, preventing the blade 4 from being placed backwards. Specifically, the viewing window is made of thermoplastic material, such as PP or ABS. In the process of molding the comb teeth 3, the blade 4 is first placed inside the mold as an insert. Then, the hot-melted plastic material is injected into the molding cavity of the mold. When the plastic material cools, the blade 4 will be connected to the cooled plastic, that is, the blade 4 and the viewing window (comb teeth 3) are integrally formed.

[0051] like Figure 5 As shown, in this embodiment, multiple reinforcing ribs 5 are provided between the comb teeth 3 and the housing 1, and the reinforcing ribs 5 are correspondingly provided with multiple combing parts 31. By designing the reinforcing ribs 5, the structure of the comb teeth 3 is further stabilized, and the comb teeth 3 are prevented from being deformed by the hair that is tangled, thereby affecting the cleaning effect on the hair on the roller brush 2.

[0052] Furthermore, the reinforcing rib 5 is connected to the main body 30, the combing part 31 and the shell 1 at the same time, in order to ensure the structural stability of the entire comb tooth 3.

[0053] The reinforcing rib 5 is located on the side of the comb tooth 3 away from the roller brush 2, and the reinforcing rib 5 is perpendicular to the main body 30. The purpose of this design is that the reinforcing rib 5 can not only play a fixing role, but also play a pre-separation role for the tangled hair.

[0054] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
