Description

Technical Field

[0001] This invention belongs to the field of cleaning equipment technology, and particularly relates to a cleaning machine and its floor brush. Background Technology

[0002] As people's living standards improve, cleaning machines have entered more and more households, playing an important role in floor cleaning.

[0003] Cleaning machines typically use brushes and vacuum (water) devices together. To improve the cleanliness of the floor, it is often necessary to push and pull the brush back and forth repeatedly. However, the current cleaning machine structure is a unidirectional operation structure. When it is necessary to push and pull the brush back and forth repeatedly to clean the floor, it will cause dust or water stains to be moved back and forth, which will cause trouble for the cleaning work, increase labor intensity, and reduce labor efficiency.

[0004] In short, the current structure of cleaning machines has the technical problem that dust or water stains on the ground can be easily moved back and forth during the cleaning process. Summary of the Invention

[0005] In view of this, embodiments of the present invention provide a cleaning machine and its floor brush to solve the technical problem that the current cleaning machine structure makes it easy for dust or water stains on the ground to be moved back and forth during the cleaning process.

[0006] This invention provides a floor brush, including a base (10), an intake port (20) disposed on the base (10) and facing the ground, a support assembly (30) with adjustable support height, and a brush body (40) for cleaning the floor;

[0007] The suction port (20) is connected to the main body of the cleaning machine via a pipe (210);

[0008] One end of the support component (30) is connected to the base (10), and the other end is supported on the ground;

[0009] When the base (10) moves back and forth on the ground, the support assembly (30) changes the support height, causing the suction port (20) and the brush body (40) to detach from or contact the ground.

[0010] Furthermore, the brush body (40) is disposed between the support assembly (30) and the suction port (20).

[0011] Furthermore, the brush body (40) is a roller brush (410) disposed on the base (10).

[0012] Furthermore, the support assembly (30) includes a fixing member (310) and a slider (320); the fixing member (310) is connected to the base (10) and has a receiving cavity (3101); the first end (3201) of the slider (320) is received in the receiving cavity (3101), the second end (3202) is supported on the ground, and the slider (320) slides in the receiving cavity (3101) to change the support height of the support assembly (30).

[0013] Furthermore, the fastener (310) includes a first wall (3102), a second wall (3103), and a third wall (3104);

[0014] The first wall (3102) and the second wall (3103) are arranged on both sides of the receiving cavity (3101) along the moving direction of the base (10), and the height of the first wall (3102) is less than the height of the second wall (3103).

[0015] The third wall (3104) is connected to the ends of the first wall (3102) and the second wall (3103) away from the ground.

[0016] Furthermore, the end of the slider (320) supported on the ground is provided with an anti-slip layer (3203).

[0017] Furthermore, the floor brush also includes a roller (50), which is disposed at one end of the base (10) and in contact with the ground.

[0018] Furthermore, along the moving direction of the base (10), the support assembly (30) and the roller (50) are respectively disposed at the two ends of the base (10), and the second wall (3103) is located between the first wall (3102) and the roller (50).

[0019] Furthermore, along the moving direction of the base (10), the suction port (20) and the roller (50) are respectively located at the two ends of the base (10), and the first wall (3102) is located between the second wall (3103) and the roller (50).

[0020] The cleaning machine and its floor brush provided in this embodiment of the invention, when the base (10) of the floor brush moves back and forth on the ground, by changing the support height of the support component (30) used to support the base (10), the suction port (20) and brush body (40) provided on the base are driven to leave the ground or come into contact with the ground. This avoids the suction port (20) and brush body (40) from carrying dust or water stains on the ground back and forth when the floor brush pulls back the base (10) repeatedly to clean the ground, thereby reducing the labor intensity of repeated cleaning and improving cleaning efficiency.

The scope of protection of this invention is determined by the appended claims.

[0032] It should also be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes said element. Specific Implementation

[0034] Please refer to Figure 1 This is a cross-sectional structural diagram of a floor brush provided in an embodiment of the present invention. The floor brush includes a base 10, a suction port 20, a support component 30, and a brush body 40.

[0035] The suction port 20 is located on the base 10 and faces the ground below the base 10. The suction port 20 is connected to the main body of the cleaning machine through the pipe 210 and, under the suction of the main body of the cleaning machine, adsorbs and cleans the dust and / or water stains on the ground.

[0036] The brush body 40 is mounted on the base 10. The brush body 40 includes, but is not limited to, a cylindrical structure or a cuboid structure. The cleaning surface of the brush body 40 faces the ground, and the cleaning surface of the brush body 40 has bristles or a cleaning cloth or cleaning floss that can replace the bristles. The brush body 40 can move on the ground under the drive of the base 10 to clean the ground. It should be noted that when the brush body 40 is a cylindrical structure, the brush body 40 rolls and rubs on the ground to clean the ground; when the brush body 40 is a cuboid structure, the brush body 40 moves back and forth on the ground to rub and clean the ground.

[0037] One end of the support component 30 is connected to the base 10, and the other end is supported on the ground. The support component 30 supports the base 10, and its support height is adjustable. When the base 10 moves back and forth on the ground, the support component 30 changes its support height, causing the suction port 20 and the brush body 40 to either detach from or contact the ground. Specifically, for example, when the base 10 moves forward on the ground, the support height of the support component 30 decreases, the distance between the base 10 and the ground decreases, and the suction port 20 and the brush body 40 will contact the ground. At this time, water stains, dirt, or dust on the ground can be cleaned through the friction cleaning of the brush body 40 and the suction force of the suction port 20. If the base 10 fails to clean the floor to the desired cleanliness after one forward movement, it needs to be pulled back to the original cleaning position for a second cleaning. This involves moving the base 10 backward on the floor, which is the opposite of the previous movement. As the base 10 moves backward, the support height of the support assembly 30 increases, raising the base 10. The suction port 20 and the brush body 40 then detach from the floor, preventing them from contacting the floor and thus avoiding the repeated movement of dust or water stains. This reduces the labor intensity of repeated cleaning and improves cleaning efficiency.

[0038] It should be noted that the present invention does not impose excessive limitations on the placement of the support component 30 on the base 10. Its main function is to support the base 10, ensuring that the suction port 20 and the brush body 40 on the base 10 are in contact with or detached from the ground when the support height changes. In a preferred embodiment, the support component 30 is positioned in the middle of the base 10, so that the base 10 can separate from or contact the ground when the support height of the support component 30 changes.

[0039] Furthermore, in order to quickly and promptly absorb and clean water stains, dirt, or dust after the brush body 40 has brushed, the brush body 40 and the suction port 20 are generally arranged adjacent to each other. In a preferred embodiment, the brush body 40 is arranged between the support component 30 and the suction port 20 to ensure that the brush body 40 and the suction port 20 are arranged adjacent to each other.

[0040] Additionally, please combine Figure 3 In a preferred embodiment of the present invention, the brush body 40 is a roller brush 410 disposed on the base 10. The roller brush 410 has a cylindrical structure, and the surface of the cylinder is provided with bristles, a cleaning cloth, or cleaning floss for cleaning. The roller brush 410 rolls and rubs on the ground to clean the ground. The brush body 40 with this structure works together with the suction port 20 to improve the cleaning quality of the floor brush on the ground.

[0041] Further integration Figure 2 The support assembly 30 includes a fixing member 310 and a slider 320; the fixing member 310 is connected to the base 10 and has a receiving cavity 3101; one end of the slider 320 is received in the receiving cavity 3101 and the other end is supported on the ground, and the slider 320 slides in the receiving cavity 3101 to change the support height of the support assembly 30.

[0042] Specifically, the fixing member 310 is connected to the base 10 on the side opposite to the receiving cavity 3101. The first end 3201 of the slider 320 is housed in the receiving cavity 3101, and the second end 3202 of the slider 320 is supported on the ground. The first end 3201 of the slider 320 can slide vertically and horizontally within the receiving cavity 3101. The second end 3202 of the slider 320 contacts the ground, generating friction between them. Under the action of this friction, the slider 320 will move in the direction of movement relative to the base. The slider 320 moves in the opposite direction, meaning it moves horizontally due to friction. Since the top surface of the accommodating cavity 3101 is not at a uniform height, the length of the slider 320 extending out of the accommodating cavity 3101 changes as its total length remains fixed. This changes the support height of the support assembly 30, thereby increasing or decreasing the distance between the base 10 and the ground, which in turn causes the suction port 20 and the brush body 40 to either detach from or contact the ground.

[0043] It should be noted that the shape of the accommodating cavity 3101 can be as follows: Figure 2The triangle shown can be slidable by the slider 320 in both the horizontal and vertical directions; or the shape of the accommodating cavity 3101 can be a cavity in the horizontal direction along the moving direction of the base 10. This cavity is not parallel to the ground, but forms a certain angle with the ground to ensure that the vertical height of the slider 320 changes when it slides in this cavity.

[0044] Further, the fixing member 310 includes a first wall 3102, a second wall 3103, and a third wall 3104; wherein, the first wall 3102 and the second wall 3103 are disposed on both sides of the receiving cavity 3101 along the moving direction of the base 10, and the height of the first wall 3102 is less than the height of the second wall 3103; the third wall 3104 is connected to the ends of the first wall 3102 and the second wall 3103 away from the ground.

[0045] Specifically, in order to limit the movement of the slider 320 within the accommodating cavity 3101, prevent the base 10 from lifting too high off the ground, and control the contact area between the air intake 20 and the brush body 40 and the ground, a first wall 3102 and a second wall 3103 are provided on both sides of the accommodating cavity 3101. The ends of the first wall 3102 and the second wall 3103 away from the ground are connected to form a third wall 3104. When the slider 320 slides, the first wall 3104... End 3201 abuts against the lower edge of the third wall 3104. Here, the height of the first wall 3102 is less than the height of the second wall 3103, that is, there is a height difference between the first wall 3102 and the second wall 3103, so that the third wall 3104 has an inclined angle relative to the ground to ensure that the slider 320 can slide in the vertical direction. As a result, when the slider 320 moves in the receiving cavity 3101, the length extending out of the receiving cavity 3101 will change, that is, the support height of the support assembly 30 will change.

[0046] In other preferred embodiments of the present invention, an anti-slip layer 3203 is provided at the end of the slider 320 that is supported on the ground. Here, since the slider 320 moves within the receiving cavity 3101 by relying on the friction between itself and the ground when the base 10 moves on the ground, providing the anti-slip layer 3203 on the second end 3202 of the slider 320 that is supported on the ground can effectively increase the friction between the slider 320 and the ground, making the movement of the slider 320 within the receiving cavity 3101 smoother.

[0047] Meanwhile, to facilitate smoother movement of the base 10 on the ground and improve its stability during movement, a roller 50 is provided at one end of the base 10. The roller 50 is connected to the base 10 via a connecting shaft, and its outer diameter contacts the ground. Here, the roller 50 is located at one end of the base 10, while the suction port 20, the support assembly 30, and the brush body 40 are located at the other end. When the base 10 moves on the ground, the end with the roller remains in contact with the ground. Only by changing the support height of the support assembly 30 can the ends with the suction port 20, support assembly 30, and brush body 40 be raised or lowered, thereby causing the suction port 20 and brush body 40 to either detach from or contact the ground.

[0048] Please refer to Figure 1 In a preferred embodiment of the present invention, along the moving direction of the base 10, the support assembly 30 and the roller 50 are respectively disposed at two ends of the base 10, and the second wall 3103 is located between the first wall 3102 and the roller 50. Specifically, along the moving direction of the base 10, the support assembly 30 and the roller 50 are located at the two ends of the base 10, while the second wall 3103 is located between the first wall 3102 and the roller 50. The brush body 40 and the suction port 20 are located between the support assembly 30 and the roller 50. This invention does not impose too many restrictions on the specific positions of the brush body 40 and the suction port 20; both can be closer to the support assembly 30. This embodiment is described with the brush body 40 located between the suction port 20 and the support assembly 30 as an example. As shown in the figure, the brush body 40 is closer to the support assembly 30 than the suction port 20. However, it should be noted that the brush body 40 and the suction port 20 are generally located at the end of the base 10 near the support assembly 30. In this way, when the support height of the support assembly 30 changes, the brush body 40 and the suction port 20 can be quickly lifted off the ground or come into contact with the ground, improving the responsiveness of the floor brush and enhancing the user experience of the floor brush.

[0049] Please refer to the following when using it. Figure 4When the base 10 moves forward (as indicated by the arrow in the figure), the slider 320 moves backward under the action of ground friction (as indicated by the arrow in the figure), thus contacting the second wall 3103 and limiting its movement. Simultaneously, the slider 320 moves upward within the receiving cavity 3101, reducing the length extending beyond the cavity and consequently reducing the support height of the support assembly 30. This reduces the distance between the base 10 and the ground, causing the brush body 40 and the suction port 20 to contact the ground. Through the friction cleaning of the brush body 40 and the suction force of the suction port 20, water stains, dust, and dirt on the ground are cleaned. When a second cleaning of the cleaned surface is required, or when the brush is pulled back for other reasons, please refer to... Figure 5 When the base 10 moves backward (as indicated by the arrow in the figure), the slider 320 moves forward under the action of ground friction (as indicated by the arrow in the figure), and then contacts the second wall 3102, which acts as a limit. At the same time, the slider 320 moves downward in the receiving cavity 3101, increasing the length extending out of the receiving cavity 3101, thereby increasing the support height of the support assembly 30, that is, increasing the distance between the base 10 and the ground. This causes the brush body 40 and the suction port 20 to detach from the ground. Since the brush body 40 and the suction port 20 are detached from the ground and do not contact the ground, it can prevent water stains, dust, and dirt under the base 10 from being transported to other places or contaminating the cleaned ground when dragging the floor brush due to the brush body 40 and the suction port 20 contacting the ground.

[0050] Additionally, please refer to Figure 3In another preferred embodiment of the present invention, along the moving direction of the base 10, the suction port 20 and the roller 50 are respectively disposed at two ends of the base 10, and the first wall 3102 is located between the second wall 3103 and the roller (50). Specifically, along the moving direction of the base 10, the suction port 20 and the roller 50 are located at the front and rear ends of the base 10, respectively, while the second wall 3103 is disposed close to the suction port 20, and the first wall 3102 is disposed close to the roller 50, such that the first wall 3102 and the second wall 3103 are located between the suction port 20 and the roller 50, and the first wall 3102 is located between the second wall 3103 and the roller (50). The brush body 40 and the support assembly 30 are located between the suction port 20 and the roller 50. This invention does not impose excessive limitations on the specific positions of the brush body 40 and the support assembly 30; both can be closer to the suction port 20. This embodiment describes the brush body 40 as being located between the support assembly 30 and the suction port 20, as shown in the figure. The brush body 40 is closer to the suction port 20 than the support assembly 30. However, it should be noted that the brush body 40 and the support assembly 30 are generally located at the end of the base 10 near the suction port 20. This allows the brush body 40 and the suction port 20 to quickly detach from or contact the ground when the support height of the support assembly 30 changes, improving the responsiveness of the floor brush and enhancing the user experience.

[0051] Please refer to the following when using it. Figure 6 When the base 10 is pulled back completely, i.e., when it moves in the direction of the arrow in the figure, the slider 320 moves forward under the action of ground friction, as shown by the arrow in the figure, and then contacts the second wall 3103, which acts as a limit to it. At the same time, the slider 320 moves upward in the receiving cavity 3101, so that the length extending out of the receiving cavity 3101 is reduced, thereby reducing the support height of the support assembly 30, i.e., reducing the distance between the base 10 and the ground. This causes the brush body 40 and the suction port 20 to contact the ground. Through the friction cleaning of the brush body 40 and the suction force of the suction port 20, water stains, dust and dirt on the ground are cleaned. When a second cleaning of the cleaned bottom surface is required, or when the floor brush is pushed forward for other reasons, please refer to Figure 7When the base 10 is pushed forward (as indicated by the arrow in the figure), the slider 320 moves backward under the action of ground friction (as indicated by the arrow in the figure), and then contacts the second wall 3102, which acts as a limit. At the same time, the slider 320 moves downward in the receiving cavity 3101, increasing the length extending out of the receiving cavity 3101, thereby increasing the support height of the support assembly 30, that is, increasing the distance between the base 10 and the ground. This causes the brush body 40 and the suction port 20 to detach from the ground. Since the brush body 40 and the suction port 20 are detached from the ground and do not contact the ground, it can prevent water stains, dust, and dirt below and in front of the base 10 from being transported to other places or contaminating the cleaned ground when dragging the floor brush due to the brush body 40 and the suction port 20 contacting the ground.

[0052] In addition, this invention also provides a cleaning machine, which includes a main body and the floor brush described in the above embodiments. The main body is connected to the suction port 20 through the pipe 210. The main body provides adsorption force to the suction port 20 through the pipe 210 to adsorb water stains, dust, etc., so as to adsorb and clean water stains, dust, etc. on the ground. It is conceivable that a dust collection chamber is also provided inside the main body or the floor brush structure for collecting water stains, dust, etc. on the ground. For the detailed structure of the floor brush, please refer to the description of the above embodiments, which will not be repeated here. The cleaning machine provided by this invention can avoid transporting water stains, dust, etc. on the ground to other places during the cleaning process, which would cause unnecessary trouble for the cleaning work or cause secondary pollution to the cleaned ground, reduce the labor intensity of repeated cleaning, and improve cleaning efficiency.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
