[0002] As living standards gradually improve, people's demands for quality of life are also increasing. More and more people are laying beautiful flooring or tiles on their homes. Flooring materials are diverse, such as wood or stone. When flooring or tiles get dirty and need cleaning, the traditional method is to use brooms, mops, or trolleys. This method is time-consuming and laborious, and it doesn't increase people's interest in cleaning, making it difficult to maintain a clean indoor environment. Therefore, the emergence of cleaning equipment has, to some extent, solved the problem of cumbersome cleaning methods. However, during operation, debris from the surface to be cleaned can easily become entangled in the front wheels of the cleaning equipment, causing it to move slowly or not at all. Therefore, a new type of cleaning brush head needs to be designed to ensure the normal movement of the cleaning equipment. Utility Model Content

Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the article or device that includes said element.

[0041] In related technologies, during the operation of cleaning equipment, the objects wrapped around the surface to be cleaned or the cleaning parts are easily entangled in the front wheels of the cleaning equipment, causing the cleaning equipment to move poorly or not at all. Therefore, it is necessary to design a new type of cleaning brush head to ensure the normal movement of the cleaning equipment.

[0042] This disclosure provides a cleaning brush head, comprising: a housing having a receiving space configured to receive a cleaning component; a roller connected to the housing and configured to contact a surface to be cleaned; a roller shaft, the roller being connected to the housing via the roller shaft, the roller being rotatable about the roller shaft; and the diameter of the roller gradually decreasing from the position where the roller shaft is connected to the housing along the extending direction of the roller shaft.

[0043] The cleaning brush head provided in this disclosure can prevent hair and other easily tangled objects from getting tangled on the top and sides of the roller during the cleaning process, thus preventing the roller from becoming clogged and not working. It can also prevent hair and other easily tangled objects from entering the gap between the roller and the housing, which could cause internal damage to the cleaning brush head or affect the normal operation of the cleaning components.

[0044] The optional embodiments of this disclosure are described in detail below with reference to the accompanying drawings.

[0045] This disclosure provides a cleaning brush head 1000, such as... Figure 1 As shown, the cleaning brush head 1000 includes: a housing 1100, a cleaning component 1200, and a roller 1300. Specifically, as... Figure 2 As shown, Figure 2 The diagram shows a bottom view of the cleaning brush head 1000. The housing 1100 has a receiving space 1001 for accommodating the cleaning component 1200. A drive motor rotates the cleaning component 1200 at high speed to clean the surface to be cleaned. The receiving space 1001 has a bottom opening through which the cleaning component 1200 contacts the surface to be cleaned. The receiving space 1001 also has a front opening 1002; "front" refers to the forward direction of the cleaning brush head 1000. The front opening 1002 is located on the side wall of the housing 1100 and communicates with the receiving space 1001. When the cleaning brush head 1000 cleans the surface, due to the high-speed rotation of the cleaning component 1200, external air is drawn into the receiving space 1001 through the front opening 1002. Furthermore, stains and impurities on the surface to be cleaned are also drawn into the receiving space 1001. In other words, while the cleaning component 1200 cleans the surface, it simultaneously draws impurities into the cleaning device through the cleaning brush head 1000.

[0046] In some embodiments, a roller brush 1300 is provided within the front opening 1002. Specifically, rollers 1300 are provided on the sidewalls of the front opening 1002. The rollers 1300 can be arranged in pairs, positioned on either side of the centerline of the cleaning member 1200, and configured to contact the surface to be cleaned, so as to feed the material wrapped around the surface to be cleaned into the front opening 1002. Figure 3As shown, the roller 1300 can be a conical roller, and the conical surface of the conical roller is in contact with the surface to be cleaned. The roller 1300 has a first end 1301 and a second end 1302. In the axial direction of the roller 1300, the radial cross-sectional area of ​​the first end 1301 is greater than the radial cross-sectional area of ​​the second end 1302.

[0047] As the cleaning brush head 1000 moves, the roller 1300 rotates accordingly. When the roller 1300 rotates in contact with the surface to be cleaned, dirt, hair, and other debris may become entangled on its surface. Under the centrifugal force of the rotating roller 1300, as the cleaning brush head 1000 rotates, the entangled debris on the roller 1300 surface is conveyed from the first end 1301 towards the second end 1302. Through friction and rotation between the roller 1300 and the ground, the entangled debris is dislodged from the roller 1300 surface and, under the action of the two opposing rollers 1300, enters the front opening 1002. The suction of the cleaning device then draws the debris from the cleaning brush head 1000 into the dust collection box.

[0048] In some embodiments, in a plane passing through the axis of the roller 1300 and perpendicular to the surface to be cleaned, the upper or lower side of the roller 1300 is a straight line or a curve, that is, the rolling surface of the roller 1300 is a straight line or a curve. Such a roller 1300, where the rolling surface is a straight line, can be a flat roller or a straight roller, mainly used for linear motion on a plane to ensure stable transport of objects along a straight direction.

[0049] In other embodiments, the upper and lower sides of the roller 1300 are straight lines or curves in a plane passing through the axis of the roller 1300 and perpendicular to the surface to be cleaned; that is, the rolling surface of the roller 1300 is a straight line and a curve, such as an irregularly shaped curved roller.

[0050] In some embodiments, the upper or lower side of the roller 1300 is an arc in a plane passing through the axis of the roller 1300 and perpendicular to the surface to be cleaned.

[0051] In other embodiments, the upper and lower sides of the roller 1300 are curved in a plane passing through the axis of the roller 1300 and perpendicular to the surface to be cleaned.

[0052] It should be noted separately that this disclosure does not impose specific limitations on the shape and structure of the roller 1300. The roller 1300 can be a conical roller or a roller with other shapes and structures.

[0053] In some embodiments, multiple pairs of rollers 1300 may be provided, with each pair of rollers 1300 positioned on both sides of the front opening 1002 to prevent tangled material from entering the gap between the rollers 1300 and the housing 1100. The combined action of multiple sets of rollers 1300 can prevent hair and other tangled material from wrapping around the cleaning component 1200 or getting into the gap between the cleaning component 1200 and the housing 1100. Specifically, as the cleaning brush head 1000 moves relative to the surface to be cleaned, the cleaning component 1200 cleans the surface, and the rollers 1300 rotate relative to the surface. Under the centrifugal force of the rotating rollers 1300, the tangled material wrapped around the surface of the rollers 1300 is transported from the first end 1301 towards the second end 1302, and finally falls off the surface of the rollers 1300 into the front opening 1002. Under the suction of the cleaning device, the tangled material is sucked into the dust collection box by the cleaning brush head 1000.

[0054] In some embodiments, during the cleaning process of the cleaning brush head 1000, whether it moves forward or backward, the cleaning method involves the high-speed rotation of the cleaning component 1200 to remove impurities from the surface. Therefore, regardless of the direction of movement of the cleaning brush head 1000, there is a risk of debris becoming entangled in the cleaning component 1200. Based on this, the rollers 1300 of this disclosure can be positioned in front of or behind the cleaning component 1200 in its direction of movement. Alternatively, rollers 1300 can be simultaneously positioned in both the front and rear openings 1002, with multiple sets of rollers 1300 working together to block and guide entangled debris into the front openings 1002.

[0055] In some embodiments, the roller 1300 is mounted obliquely to the housing 1100, specifically, as shown in the example below. Figure 4 As shown, the angle between the length extension direction of the roller shaft 1310 of the roller 1300 and the surface to be cleaned is α. The angle α is between 15 and 45 degrees. When the roller shaft 1310 of the roller 1300 has a certain angle with the surface to be cleaned, it will be more flexible when pushing the cleaning brush head 1000 to turn. An angle of 15 to 45 degrees allows the roller 1300 to better change its direction of movement when turning. If the angle between the length extension direction of the roller shaft 1310 of the roller 1300 and the surface to be cleaned is less than 15 degrees, the cleaning brush head 1000 may not turn sensitively; if the angle between the length extension direction of the roller shaft 1310 of the roller 1300 and the surface to be cleaned is greater than 45 degrees, the conical surface of the roller 1300 will have difficulty adhering to the surface to be cleaned, and will not be able to effectively prevent entanglement.

[0056] Therefore, this angled design allows the roller 1300 to maintain good stability and maneuverability on uneven surfaces to be cleaned. For example, on surfaces with a certain slope or undulation, the roller 1300 can use its angle to automatically adjust its contact with the ground, preventing the cleaning brush head 1000 from being obstructed. In addition, the angle between the roller shaft 1310 and the surface to be cleaned can decompose the weight of the cleaning brush head 1000 itself and the forces generated during its movement. For example, on an inclined plane, this angle can decompose the weight of the device into two components: one perpendicular to the roller 1300 and the other along the direction of the roller 1300, making the device easier to control on inclined planes.

[0057] In some embodiments, the cone angle of the roller 1300 is 15 to 60 degrees. For example... Figure 5 As shown, the angle between the conical surface of the roller 1300 and the extension line of the roller shaft 1310 is β, which is between 15 and 60 degrees, facilitating steering. During steering, different conical surface angles can change the frictional force distribution of the roller 1300 in contact with the ground, allowing the cleaning brush head 1000 to achieve steering operation with less force, compensating for the effects of installation errors or uneven ground, and making the movement of the cleaning brush head 1000 more stable. In addition, the conical surface angle also affects the force decomposition; a suitable conical surface angle allows the roller 1300 to reasonably distribute the force when subjected to external forces, reducing excessive local pressure.

[0058] In some embodiments, the roller 1300 is made of metal and plastic.

[0059] In some embodiments, the roller 1300 is made of metal or plastic. The roller 1300 can be a metal wheel or a plastic wheel. Metal wheels can be made of metals such as aluminum alloy and stainless steel, which have high strength and hardness, can withstand greater weight and pressure, are not easily deformed, and wear relatively slowly. However, metal wheels have poor shock absorption performance and may generate significant noise during rolling. Plastic wheels, on the other hand, are mainly made of plastics such as polyurethane and nylon, which are relatively soft, have some elasticity, and are lightweight. Plastic wheels have good shock absorption performance, can buffer vibrations, can assist the cleaning brush head 1000 in moving smoothly, and have low rolling noise, providing a relatively quiet working environment.

[0060] In some embodiments, to prevent tangled debris from entering the cleaning brush head 1000 and preventing the cleaning component 1200 from rotating freely relative to the housing 1100, the cleaning brush head 1000 further includes a blocking component 1400. The blocking component 1400 is disposed between the roller 1300 and the housing 1100. Specifically, the blocking component 1400 is sleeved on the roller shaft 1310 and disposed between the roller 1300 and the side wall of the front opening 1002, configured to prevent tangled debris from entering and to prevent dirt from entering the gap between the roller 1300 and the housing 1100. Roller shaft 1310

[0061] Specifically, the blocking member 1400 fills the gap between the roller 1300 and the housing 1100. For example... Figure 3 As shown, the blocking member 1400 is disposed at the first end 1301 of the roller 1300 and extends axially toward the roller 1300, configured to block external impurities from entering the receiving space 1001 through the gap between the roller 1300 and the housing 1100.

[0062] In some embodiments, the blocking member 1400 is a flexible member, and the blocking member 1400 is interference-fitted with the housing 1100 and the roller 1300.

[0063] In some embodiments, the blocking member 1400 is a flexible member, and the blocking member 1400 is interference-fitted with the housing 1100 or the roller 1300.

[0064] The blocking member 1400 is disposed at the first end 1301 and extends radially annularly toward the roller 1300. In the radial cross section of the roller 1300, the diameter of the blocking member 1400 is larger than the diameter of the first end 1301. It is configured to isolate the roller 1300 from the housing 1100 to prevent entanglement on the roller 1300 from entering the receiving space 1001.

[0065] When the cleaning component 1200 is rotating at high speed in the working state, the entangled material on the surface to be cleaned will come into contact with the roller 1300 before entering the front opening 1002. Since the roller 1300 is a roller, under the action of centrifugal force, the dirt entangled on the surface of the roller 1300 will be transported from the first end 1301 toward the second end 1302. The setting of the blocking component 1400 can effectively prevent dirt from entering the receiving space 1001.

[0066] In some embodiments, the blocking member 1400 may be an annular structure made of materials such as felt, nylon, wool, acrylic, or polyester, and the maximum diameter of the blocking member 1400 is larger than the maximum diameter of the roller 1300. This prevents entanglement on the surface of the roller 1300 from moving around the blocking member 1400 toward the portion where the cleaning member 1200 connects to the housing 1100.

[0067] In some embodiments, at least a portion of the blocking member 1400 interferes with the roller 1300 to prevent entanglement from wrapping around the roller shaft 1310 and affecting the normal rotation of the roller 1300. The interference between the blocking member 1400 and the roller 1300 can be 1 / 6 to 2 / 6 of the thickness of the blocking member 1400, that is, the interference fit between the blocking member 1400 and the housing 1100 or the roller 1300 is 1 / 6 to 2 / 3 of the thickness of the blocking member. Specifically, for example... Figure 5 As shown, the interference between the blocking member 1400 and the roller 1300 is the thickness H of the overlapping portion of the blocking member 1400 and the roller 1300, and the thickness H is 1 / 6 to 2 / 6 of the thickness of the blocking member 1400.

[0068] If the interference between the blocking member 1400 and the roller 1300 is less than 1 / 6, it may not be possible to prevent the tangled material from entering the gap between the cleaning member 1200 and the housing 1100 along the first end 1301 of the roller 1300. If the interference between the blocking member 1400 and the roller 1300 is greater than 2 / 6, the roller 1300 may not be able to rotate freely or may have difficulty rotating during the movement of the cleaning brush head 1000, which is not conducive to the tangled material detaching from the roller 1300. Preferably, the interference between the blocking member 1400 and the roller 1300 is 1 / 3. At this time, the roller 1300 rotates normally during the movement of the cleaning brush head 1000 and can effectively prevent the tangled material from entering the drive end of the cleaning member 1200.

[0069] In some embodiments, when the cleaning brush head 1000 is placed flat on the surface to be cleaned, there is a gap between the blocking member 1400 and the surface to be cleaned. That is, the blocking member 1400 is eccentrically disposed on the roller shaft 1310 of the roller 1300 to avoid the roller 1300 being obstructed from rotating due to interference between the blocking member 1400 and the surface to be cleaned, thus ensuring the normal movement and deflection of the cleaning brush head 1000.

[0070] A second aspect of this disclosure provides a cleaning device, including the cleaning brush head 1000 provided in the first aspect of this disclosure. During the cleaning process, the roller 1300 of the cleaning brush head 1000 can prevent tangled material from the cleaning component 1200 from wrapping around it, thus preventing hair and other tangled material from entering the receiving space 1001 through the gap between the cleaning component 1200 and the housing 1100, causing internal damage to the cleaning brush head or affecting the normal operation of the cleaning component 1200, thereby improving the user experience.

[0071] A third aspect of this disclosure provides a cleaning system, including a base station and the cleaning equipment provided in the second aspect of this disclosure.

[0072] The specific structure, working principle, and beneficial effects of the cleaning brush head, cleaning equipment, and cleaning system provided in this disclosure can be found in any of the above embodiments of the cleaning brush head, cleaning equipment, and cleaning system, and will not be repeated here.

[0073] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the systems or apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the descriptions are relatively simple, and relevant parts can be referred to the method section.

[0074] The above embodiments are only used to illustrate the technical solutions of this disclosure, and are not intended to limit it. Although this disclosure 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.
