Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a disc brush and a floor brush structure for a cleaning machine and a cleaning machine. Background Art

[0002] As people's living standards continue to improve, cleaning machines such as floor scrubbers, vacuum cleaners, and sweepers have become widely used in daily life. As a floor cleaning device, a floor scrubber draws a mixture of dust and moisture from the floor into its storage chamber. When the floor needs to be cleaned, the user simply holds the floor scrubber and sweeps and mops the surface as it passes.

[0003] Most existing mobile cleaning devices use a roller brush as the sweeping actuator. The roller brush's rolling action brings the brush elements or bristles on its outer periphery into contact with the surface to be cleaned, thereby removing dirt adhering to the surface. While the roller brush structure covers a relatively large cleaning area, since mobile cleaning devices rely on negative pressure suction to collect dirt, the arrangement of the roller brush also has the disadvantage of blocking the airflow, which weakens the negative pressure suction to a certain extent.

[0004] In order to solve the above problems, some products use a disc brush structure instead of the traditional roller brush. Since the rotation axis of the disc brush extends vertically, there will be a rotation gap between two adjacent disc brushes. This gap is conducive to the passage of airflow, which greatly solves the problem of weakening of negative pressure suction of existing cleaning machines. For easy replacement, please refer to the applicant's previous application for patent number CN202321705720.9 in China, "A disc brush and a floor brush module and cleaning machine with the disc brush".

[0005] However, for the existing disc brush structure, the brush member at the bottom of the disc body is a rubber strip made of silicone, which has good drainage ability but weak cleaning power. Utility Model Content

[0006] The first technical problem to be solved by the present invention is to provide a disc brush for a cleaning machine that can improve the cleaning effect in view of the current status of the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a floor brush structure using the above-mentioned disc brush.

[0008] The third technical problem to be solved by the present invention is to provide a cleaning machine using the above-mentioned floor brush structure.

[0009] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a disc brush for a cleaning machine, comprising a disc body and a brush member arranged at the bottom of the disc body, characterized in that the brush member is a flexible water-absorbing member with a microporous structure.

[0010] In order to prevent the disc brush from being sucked onto the surface to be cleaned and to improve the self-cleaning effect, the number of the brush members is at least two, and they are arranged at intervals along the circumference of the disc body, and a first flow channel connected to the external air is formed between adjacent side edges of two adjacent brush members.

[0011] In order to prevent the disc brush from being sucked onto the surface to be cleaned and to improve the self-cleaning effect, the number of the brush members is at least two groups, and they are arranged at intervals along the circumference of the disc body, and a first flow channel connected to the external air is formed between adjacent side edges of two adjacent groups of brush members;

[0012] In each group of the brush members, there are at least two brush members, which are spaced apart in the radial direction of the disc body. A second flow channel connected to the adjacent first flow channels is formed between adjacent side edges of two adjacent brush members.

[0013] In order to form a through channel from the center of the disk to the periphery and improve the removal efficiency of gas, liquid and particulate waste, the center of the bottom of the disk body has a central area, each of the brushes is located on the periphery of the central area, and each of the first flow channels is connected to the central area.

[0014] In order to improve the flow guiding effect, the bottom surface of the disc body corresponding to the brush member and the first flow channel is respectively recorded as a mounting surface and a spacing surface, and a smooth transition between two adjacent mounting surfaces and spacing surfaces is formed through an arc surface.

[0015] In order to facilitate the removal of dirt, the spacing surface is an upward curved surface.

[0016] In order to facilitate the removal of dirt, the diameter of each of the first flow channels gradually increases from the inside to the outside.

[0017] In order to shield and protect the edge of the brush, protective members are provided on both sides of the brush along the circumferential direction at the bottom of the disc.

[0018] In order to achieve the shielding and protection function, the protection member is in the shape of a strip, standing upright on the side of the corresponding brush member and abutting against the side edge of the brush member.

[0019] In order to facilitate the installation of the protective member, a slot for inserting the edge of the protective member is provided on the bottom surface of the disc body.

[0020] In order to protect the easily damaged side of the brush without affecting the cleaning performance of the brush, the height of the protective member is lower than the height of the brush.

[0021] In order to help drain water from the disc area, a scraper is provided on the periphery of the disc body, and the scraper can be in contact with the surface to be cleaned when the brush is sweeping the surface to be cleaned.

[0022] In order to reduce the occupied space while ensuring a certain scraping range, the scraping member is strip-shaped and extends along the radial direction of the disc body.

[0023] In order to facilitate the installation of the scraper, a groove extending radially and penetrating to the outer peripheral wall of the disk body is provided on the bottom surface of the disk body corresponding to one of the first flow channels, and the tail end of the scraper is clamped in the groove.

[0024] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: a floor brush structure, including a shell, the interior of the shell has a dust suction chamber with an opening facing downward, and is characterized in that it includes the above-mentioned disc brush, the disc body can be rotatably installed in the dust suction chamber and its rotation axis extends vertically.

[0025] The technical solution adopted by the present invention to solve the third technical problem is: a cleaning machine, characterized in that it includes the above-mentioned floor brush structure.

[0026] Preferably, the cleaning machine is a floor scrubber.

[0027] Compared with the existing technology, the advantage of the present invention is that by setting the brush part as a flexible water-absorbing part with a microporous structure, compared with the existing rubber strips made of silicone, the microporous structure of the brush part can absorb moisture, making the brush part more efficient in cleaning the surface to be cleaned.

[0032] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0033] In the specification and claims of the present invention, directional terms such as "front," "back," "up," "down," "left," "right," "side," "top," and "bottom" are used to describe various exemplary structural parts and components of the present invention. However, these terms are used herein for convenience of description only and are based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present invention can be arranged in different orientations, these directional terms are intended for illustrative purposes only and should not be construed as limiting. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0034] Example 1:

[0035] like Figures 1 to 2 The figure shows the first preferred embodiment of the cleaning machine of the present invention. The cleaning machine can be a floor scrubber, vacuum cleaner, or sweeper, etc. This embodiment uses a floor scrubber as an example. The floor brush structure of the floor scrubber includes a housing and a disc brush.

[0036] The housing has multiple downward-facing suction chambers spaced horizontally and spaced apart. The number of disc brushes corresponds to the number of these chambers, and each disc brush is installed in its corresponding chamber. This is a conventional structure for floor scrubbers, and details can be found in the background patent, so I will not elaborate on it here.

[0037] In this embodiment, the disc brush includes a disc body 1 , a brush member 2 , a protective member 3 and a scraping member 4 .

[0038] Specifically, the disc body 1 can be rotatably installed in the corresponding dust collection chamber and its rotation axis extends vertically; the center of the bottom of the disc body 1 has a central area 10, and the bottom of the disc body 1 located at the periphery of the central area 10 has a mounting surface 11 and a spacing surface 12 arranged alternately along the circumferential direction, and the number of the mounting surfaces 11 and the spacing surfaces 12 are three; each mounting surface 11 is provided with a strip-shaped slot 111 on both sides along the circumference; one of the spacing surfaces 12 is provided with a card groove 121 extending radially and penetrating to the outer peripheral wall of the disc body 1.

[0039] There are three brush members 2, one corresponding to each of the mounting surfaces 11, with each brush member 2 bonded to the corresponding mounting surface 11. In this embodiment, the brush members 2 are flexible, water-absorbing members with microporous structures. They are made of a flexible, water-absorbing microporous material with abundant three-dimensional openings. Compared to existing rubber strips made of silicone, the microporous structure of the brush members 2 can absorb moisture, making them more efficient in cleaning the surface to be cleaned.

[0040] Specifically, a first flow channel 21 connected to the external air is formed between adjacent side edges of two adjacent brush members 2, and each first flow channel 21 is connected to the above-mentioned central area 10, thereby forming a through channel from the center of the disk to the periphery for the removal of gas, liquid and particulate garbage. The microporous structure of the brush member 2 is connected to the above-mentioned channel to form a connection between the internal and external air. In this way, on the one hand, in the process of the brush member 2 rotating with the disk body 1 to sweep the surface to be cleaned, the brush member 2 is squeezed by the surface to be cleaned, and the water and air in its microporous structure are squeezed out and centrifugally rotated out along the above-mentioned channel, thereby generating a certain negative pressure. However, due to the existence of the channel, air outside the disk area can also enter the disk area, preventing the disk brush from being sucked onto the surface to be cleaned and falling. On the other hand, during self-cleaning, the side edges of the brush member 2 can be replaced as the interface for the inflow and outflow of dirty water. Compared with the whole disk, the self-cleaning efficiency is greatly increased, and the dirty water remaining inside the brush member 2 can be reduced. In this embodiment, the brush member 2 is fan-shaped, and the diameter of each first flow channel 21 gradually increases from the inside to the outside, thereby facilitating the removal of dirt.

[0041] There are six protective members 3, two for each brush member 2. These members are located on either side of the corresponding brush member 2 along the circumferential direction. Specifically, each protective member 3 is strip-shaped, with its edge inserted into the corresponding slot 111 so that it stands upright on the side of the corresponding brush member 2 and abuts against the side edge of the brush member 2. These protective members 3 shield and protect the edges of the brush member 2, reducing the impact of solid matter and dirt on the lifespan of the microporous material. Furthermore, the protective members 3 can be made of either a hard material or a flexible silicone material, and their height is lower than that of the brush member 2. This protects the easily damaged sides of the brush member 2 without affecting its cleaning performance.

[0042] The scraper 4 is disposed around the periphery of the disc body 1 and conforms to the surface being cleaned while the brush 2 is sweeping across it, thereby helping to remove water from the disc area and reducing residual water stains on the surface during downtime. Specifically, the scraper 4 is strip-shaped and extends radially along the disc body 1. The tail end of the scraper 4 is retained within the aforementioned retaining groove 121, while the head of the scraper 4 is exposed on the outer peripheral wall of the disc body 1.

[0043] Example 2:

[0044] like Figure 3 The second preferred embodiment of the cleaning machine of the present invention is shown in FIG. The difference from the first embodiment is that:

[0045] In this embodiment, the brush member 2 is in the shape of a teardrop; the spacing surface 12 is an upward curved surface, and the two adjacent mounting surfaces 11 and the spacing surface 12 are smoothly transitioned through the curved surface. The design of the upward curved surface can make the channel between the disc brush and the surface to be cleaned wider, which is conducive to the removal of dirt.

[0046] Example 3:

[0047] like Figure 4 The third preferred embodiment of the cleaning machine of the present invention is shown in FIG. The difference from the first embodiment is that:

[0048] In this embodiment, the number of brush members 2 is three groups, and they are arranged at intervals along the circumference of the disc body 1. A first flow channel 21 connected to the external air is formed between the adjacent side edges of two adjacent groups of brush members 2. In each group of brush members 2, the number of brush members 2 is two, and they are arranged at intervals along the radial direction of the disc body 1. A second flow channel 22 connected to the adjacent first flow channel 21 is formed between the adjacent side edges of two adjacent brush members 2, thereby forming a mesh-like channel at the bottom of the disc body 1, further improving the removal efficiency of gas, liquid and particulate waste.

[0049] Taking Example 1 as an example, the working principle of this embodiment is as follows:

[0050] (1) During cleaning, the brush 2 rotates with the disc 1 to sweep the surface to be cleaned. Since the microporous structure of the brush 2 can absorb water, the brush 2 can clean the surface to be cleaned more efficiently. In addition, the brush 2 is squeezed by the surface to be cleaned, and the water and air in its microporous structure are squeezed out and centrifugally rotated out along the channel, thereby generating a certain negative pressure. However, due to the existence of the channel, air outside the disc area can also enter the disc area, preventing the disc brush from being sucked onto the surface to be cleaned and falling off;

[0051] (2) During self-cleaning, the side edges of the brush element 2 can be replaced as the interface for the inflow and outflow of dirty water. Compared with the whole plate, the self-cleaning efficiency is greatly increased and the amount of dirty water remaining inside the brush element 2 can be reduced.
