Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a floor brush device, cleaning equipment and cleaning system. Background Technology

[0002] In cleaning equipment such as floor scrubbers, sweepers, and electric mops, the roller brush is one of the important structures that ensures cleaning ability. Many cleaning devices have a self-cleaning function, which cleans the roller brush by spraying water or detergent onto it.

[0003] In existing technology, after cleaning the roller brush, the cleaning equipment blows hot air onto the roller brush to dry it. This drying method makes it difficult to dry the deeper layers of the roller brush, which can easily lead to incomplete drying, bacterial growth, or unpleasant odors. Utility Model Content

[0004] This application provides a floor brush device, cleaning equipment, and cleaning system that facilitates drying the inner layer of the roller brush, ensures the dryness of the roller brush, and prevents the growth of bacteria or the generation of odors.

[0005] In a first aspect, this application provides a floor brush device, comprising: a floor brush body having a cleaning chamber; a roller brush device rotatably disposed in the cleaning chamber for cleaning the surface to be cleaned, the roller brush device having a hollow inner cavity; and a heating device having a first end connected to the floor brush body and a second end inserted into the inner cavity of the roller brush device for heating the roller brush device.

[0006] The floor brush device of this application dries the roller brush device from the inside out by placing a heating device inside the roller brush device and heating the roller brush device. This promotes the evaporation of moisture near the inside of the roller brush device, which helps to improve drying efficiency, makes it easier to achieve complete drying of the roller brush device, and helps to prevent the roller brush device from growing bacteria or producing odors.

[0007] In one possible implementation, the roller brush device includes: a roller brush body defining an inner cavity, at least one end of the roller brush body having an opening communicating with the inner cavity along the axial direction; and an end cap disposed at the opening, through which a second end of a heating device extends into the inner cavity of the roller brush body.

[0008] In this way, the heating device passes through the end cap, which avoids the need to create a hole in the roller brush body for the heating device to pass through. When the heating device starts heating, the heat generated is concentrated in the relatively closed inner cavity, which can rapidly raise the temperature of the inner cavity and transfer the heat to the roller brush body. This helps to improve the heating efficiency of the roller brush body and save drying time. In addition, the end cap can support the heating device, and the axial mounting of the heating device helps to prevent the rotation of the roller brush from affecting the connection between the heating device and the power supply circuit.

[0009] In one possible implementation, the roller brush body has openings at both ends along the axial direction, and the end caps include a first end cap and a second end cap, which are respectively disposed over the two openings; the heating device extends into the inner cavity of the roller brush body through at least one of the first end caps and the second end cap.

[0010] Thus, the heating device and the roller brush device can be assembled in various ways, and can be assembled from either side of the roller brush device as needed.

[0011] In one possible implementation, the roller brush device further includes: a roller brush side cover for connection with the brush body, the brush body being rotatably connected to the roller brush side cover via a first end cover; and a heating device extending into the inner cavity of the brush body through a second end cover.

[0012] In this way, the roller brush body and the floor brush body can be rotated together, so that the roller brush body can rotate and contact the surface to be cleaned, and the surface to be cleaned can be cleaned by rotation.

[0013] In one possible implementation, the brush body includes: a brush housing having a mounting portion located on the side of the second end cap of the cleaning chamber, the mounting portion having a mounting cavity and a connecting port connecting the mounting cavity and the cleaning chamber; a drive device including a drive assembly and an output component, the drive assembly being disposed in the mounting cavity, the output component being drively connected to the drive assembly to rotate under the drive of the drive assembly, the output component extending into the cleaning chamber from the connecting port, the second end cap being fixedly connected to the output component, and the output component having an assembly channel extending axially along the brush body; a first end of a heating device being fixedly connected to the mounting portion, and a second end of the heating device extending into the inner side of the brush body via the assembly channel.

[0014] Thus, the drive assembly is fixed in the mounting cavity, the output component is fixedly connected to the second end cover, the second end cover is fixedly connected to the roller brush body, the drive assembly drives the output component to rotate, the output component drives the roller brush body to rotate through the second end cover, the first end cover rotates relative to the side cover of the roller brush, and at the same time, the first end of the heating device is fixedly connected to the mounting part to ensure that the position of the heating device remains stationary and does not rotate with the roller brush body.

[0015] In one possible implementation, the output component includes a drive portion, a rotating support portion, and a connecting portion distributed along the axial direction of the roller brush device. The drive portion is located in the mounting cavity and is used to connect with the drive assembly. The connecting portion is located in the cleaning cavity and is fixed to the inner side of the second end cap. The drive device includes a bearing component that is sleeved on the rotating support portion so that the output component can rotate relative to the brush housing.

[0016] Thus, by fitting a bearing onto the rotating support and having it abut against the brush housing, the output component can be supported and prevented from breaking in the middle. This also reduces the friction between the output component and the brush housing, ensuring that the output component can rotate relative to the brush housing. Furthermore, it helps improve the rotational accuracy of the main shaft of the roller brush body.

[0017] In one possible implementation, the drive assembly includes: a power source; a mounting bracket disposed in the mounting cavity, with a bearing disposed between the rotating support and the mounting bracket; and a drive belt sleeved on the drive portion and located radially inside the mounting bracket, the drive belt being configured to drive the output component to rotate under the drive of the power source.

[0018] Thus, due to the elasticity of the drive belt, the rotation of the output component via the drive belt helps to mitigate impact and vibration, ensuring smooth rotation of the roller brush body and reducing noise during operation. Furthermore, when the resistance experienced by the roller brush body is too great, causing overload, slippage will occur between the drive unit and the drive belt, preventing damage to other components within the cleaning equipment due to overload. In addition, the mounting bracket, located within the mounting cavity, supports the output component, and the bearings can be fixed to the mounting bracket using a rubber-coating process to ensure the stability of the output component.

[0019] In one possible implementation, the drive assembly includes: a pulley cover fixed to the side of the mounting bracket facing away from the cleaning chamber, the pulley cover having a mounting hole opposite to the assembly channel, a heating device passing through the mounting hole, the heating device having a connection terminal extending from the mounting hole for connection to a power source.

[0020] In this way, the position of the heating device and the mounting bracket can be limited by the pulley cover, which helps to ensure the stable rotation of the roller brush body and maintain the stability of the heating device.

[0021] In one possible implementation, the inner wall of the assembly channel is provided with a first sealing groove, and the drive device further includes a first sealing ring disposed in the first sealing groove to seal the gap between the heating device and the output component.

[0022] In this way, the inner cavity of the roller brush body can be ensured to be a closed cavity, which is conducive to retaining the heat generated by the heating device in the inner cavity, so that the temperature of the inner cavity can rise rapidly, thereby improving the drying efficiency of the roller brush body.

[0023] In one possible implementation, the roller brush body includes: a cylinder and a cleaning body sleeved on the outside of the cylinder, wherein the cylinder is a metal part.

[0024] In this way, once the heating device starts heating, the cylinder can quickly transfer heat to the cleaning body, thereby drying the cleaning body from the inside out, which helps to save drying time and improve the drying efficiency of the cleaning body.

[0025] In one possible implementation, the cylinder is made of aluminum alloy.

[0026] In this way, the structural strength requirements of the roller brush body can be met, ensuring that the roller brush body does not deform. It can also ensure that heat is quickly transferred to the cleaning body, saving drying time. At the same time, it can also reduce the weight of the floor brush device, which can improve the user experience of the cleaning equipment.

[0027] In one possible implementation, the heating device includes at least one of a heating rod, a heating wire, and a heating tube.

[0028] This allows the heating device to heat up rapidly after being powered on, thus improving the drying efficiency of the roller brush device.

[0029] Secondly, this application provides a cleaning device, including any of the above-mentioned floor brush devices.

[0030] This allows for rapid drying of the roller brush device, ensuring its dryness, preventing bacterial growth or odors, and improving the cleaning performance and lifespan of the cleaning equipment.

[0031] Thirdly, this application provides a cleaning system, including: a cleaning base station; and a cleaning device, wherein the cleaning base station is configured to clean the roller brush device of the cleaning device.

[0032] In this way, dirt can be removed from the roller brush device, keeping the roller brush device clean. Attached Figure Description

[0052] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0054] As shown in the background section, in cleaning equipment such as floor scrubbers, sweepers, and electric mops, the roller brush is one of the important structures that ensures cleaning ability. Many cleaning equipment have a self-cleaning function, which cleans the roller brush by spraying water or detergent onto it.

[0055] In the prior art, after the cleaning equipment cleans the roller brush, hot air is blown onto the roller brush for a preset time to dry it.

[0056] However, blowing hot air only on the outside of the roller brush makes it difficult to dry the deeper parts of the roller brush. Since the humidity and other factors of the environment where the cleaning equipment is located are constantly changing, blowing hot air on the roller brush for a fixed period of time can easily lead to the inside of the roller brush not being completely dry, which can breed bacteria or produce odors.

[0057] To address the aforementioned technical problems, this application provides a floor brush device, cleaning equipment, and cleaning system. The floor brush device includes a floor brush body, a roller brush assembly, and a heating device. The floor brush body has a cleaning chamber, and the roller brush assembly is rotatably disposed within the cleaning chamber, cleaning the surface to be cleaned through rotational contact. The roller brush assembly has an inner cavity, and the first end of the heating device is connected to the floor brush body to at least partially fix the heating device within the inner cavity. When using the cleaning equipment, the roller brush assembly is rotated into contact with the surface to be cleaned for cleaning. After cleaning, the roller brush assembly can be rinsed with clean water or cleaning solution to remove dirt from its surface. After rinsing, the roller brush assembly is heated by the heating device until it is completely dry, preventing the roller brush assembly from remaining damp for extended periods, thus avoiding bacterial growth and odor. In this way, when drying the roller brush device, the heating device heats the inner cavity of the roller brush device, and the drying is carried out from the inside out. When the outer surface of the roller brush device is dry, it proves that the roller brush device is completely dry. In addition, even if the heating time of the heating device is short and the roller brush device is not completely dried, the wet part of the roller brush device is located on the outer surface of the roller brush device, which is easier to air dry naturally. Therefore, the roller brush device provided in this application is easier to completely dry, which helps to avoid the growth of bacteria or the generation of odors in the roller brush device.

[0058] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings:

[0059] It should be noted that the floor brush device provided in this application embodiment can be applied to cleaning equipment such as sweeping machines, floor scrubbers, and sweeping robots.

[0060] See Figure 1 and Figure 2 As shown, the floor brush device 100 of this application embodiment includes: a floor brush body 110, a roller brush device 120, and a heating device 130. The floor brush body 110 has a cleaning cavity 1111; the roller brush device 120 is rotatably disposed in the cleaning cavity 1111 and cleans the surface to be cleaned by rotating into contact with the surface to be cleaned. The roller brush device 120 has a hollow inner cavity 1211a; the first end of the heating device 130 is connected to the floor brush body 110, and the second end passes through the inner cavity 1211a of the roller brush device 120. The heating device 130 is used to heat the roller brush device 120.

[0061] In this embodiment, the roller brush device 120 is rotatably connected to the floor brush body 110, and the heating device 130 can extend along the axial direction of the roller brush device 120. The first end of the heating device 130 is fixedly connected to the floor brush device 100 to ensure that the position of the second end of the heating device 130 remains unchanged and is always located in the inner cavity 1211a of the roller brush device 120. After the cleaning equipment completes the cleaning operation through the roller brush device 120, it can spray clean water, detergent, etc. onto the roller brush device 120 to clean it and remove dirt from it. The specific cleaning method is not limited in this embodiment. After cleaning, the heating device 130 starts heating in the inner cavity 1211a, and the temperature in the inner cavity 1211a rises, thereby drying the roller brush device 120 from the inside out.

[0062] In the prior art, the roller brush device 120 is dried from the outside by hot air. If the hot air supply time is short, the roller brush device 120 may be dry on the outside but still damp inside. The inside of the roller brush device 120 remains closed and cannot be ventilated, making it difficult to air dry naturally, which leads to the growth of bacteria in the roller brush device 120. However, the floor brush device 100 provided in this application provides drying of the roller brush device 120 through the inner cavity 1211a, which can ensure that the roller brush device 120 is at least dry inside. Even if the heating time of the heating device 130 is short and the roller brush device 120 is not completely dry, the part of the roller brush device 120 that remains damp is the part near the outer surface of the roller brush device 120. This part can also be kept dry by natural air drying or other methods. Therefore, the floor brush device 100 of this application is more conducive to ensuring that the roller brush device 120 is completely dry, thereby helping to avoid the growth of bacteria and the generation of odors due to prolonged dampness in the roller brush device 120.

[0063] Furthermore, compared to the prior art where hot air dries the roller brush device 120 from the outside in, the heating device 130 of this application dries the roller brush device 120 from the inside out, which is more conducive to promoting the evaporation of moisture near the inner side of the roller brush device 120, thereby improving the drying efficiency of the roller brush device 120 and saving drying time.

[0064] Furthermore, the heating time of the heating device 130 can be preset according to the basic time required for drying the roller brush device 120. Each time the roller brush device 120 needs to be dried, the heating device 130 heats for the preset time to ensure that the roller brush device 120 is basically dry. In this way, even if the roller brush device 120 is not completely dry due to environmental humidity or other reasons, only the outer surface of the roller brush device 120 will be damp, which can be quickly and naturally dried. Alternatively, a corresponding detection device can be set in the cleaning chamber 1111 to detect the dryness and wetness of the roller brush device 120. When the humidity of the roller brush device 120 is detected to be lower than the preset value, the heating device 130 stops heating. Of course, the specific heating time and working mode of the heating device 130 are not limited in this embodiment, as long as the roller brush device 120 is basically dry.

[0065] In addition to the heating device 130, a blower can also be installed in the cleaning chamber 1111. When the roller brush device 120 needs to be dried, the heating device 130 heats the roller brush device 120 from the inside out, while the blower can be started at the same time to blow air into the roller brush device 120 from the outside in, thus drying the roller brush device 120. In this way, the heating device 130 and the blower simultaneously dry the roller brush device 120 from both inside and outside, which can further accelerate the drying speed of the roller brush device 120, improve the drying efficiency, and also help to keep the roller brush device 120 dry as a whole, thereby avoiding the roller brush device 120 from producing odors and growing bacteria, and ensuring the cleanliness of the roller brush device 120.

[0066] Therefore, the floor brush device 100 provided in this application embodiment can quickly dry the roller brush device 120 from the inside out, ensuring that the roller brush device 120 remains dry as a whole, which helps to keep the roller brush device 120 clean and avoids the growth of bacteria due to prolonged dampness.

[0067] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the roller brush device 120 of this application embodiment includes: a roller brush body 121 and an end cap 122. The roller brush body 121 defines an inner cavity 1211a. At least one end of the roller brush body 121 along the axial direction has an opening communicating with the inner cavity 1211a. The end cap 122 is disposed at the opening, and the second end of the heating device 130 passes through the end cap 122 into the inner cavity 1211a of the roller brush body 121.

[0068] Understandably, the end cap 122 is positioned open to close the inner cavity 1211a. The second end of the heating device 130 passes through the end cap 122 into the inner cavity 1211a. This avoids the need for a hole in the roller brush body 121 for the heating device 130 to pass through. When the heating device 130 starts heating, the generated heat is concentrated in the relatively closed inner cavity 1211a, allowing the temperature of the inner cavity 1211a to rise rapidly and transfer the heat to the roller brush body 121. This improves the heating efficiency of the roller brush body 121 and saves drying time. In addition, the end cap 122 provides support for the heating device 130, and the axial mounting of the heating device 130 helps prevent the rotation of the roller brush body 120 from affecting the connection between the heating device 130 and the external power supply circuit.

[0069] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 3 and Figure 7As shown, in this embodiment of the application, the roller brush body 121 has openings at both ends along the axial direction. The end caps 122 include a first end cap 1221 and a second end cap 1221, which respectively cover the two openings. The heating device 130 extends into the inner cavity 1211a of the roller brush body 121 through at least one of the first end cap 1221 and the second end cap 1221. Thus, the heating device 130 and the roller brush device 120 can be assembled in various ways, and can be assembled from any side of the roller brush device 120 along the axial direction as needed.

[0070] In some embodiments, the inner cavity 1211a extends axially through the roller brush body 121. The second end of the heating device 130 can pass through one of the first end cover 1221 and the second end cover 1221 and be fixed in the inner cavity 1211a. For example, when the second end of the heating device 130 passes through the second end cover 1221 and enters the inner cavity 1211a, the first end cover 1221 is detachably connected to the roller brush body 121. Opening the first end cover 1221 allows other components to be arranged in the inner cavity 1211a without affecting the heating device 130, or allows for maintenance of the heating device 130. Meanwhile, since the roller brush body 121 has a limited lifespan, it needs to be replaced at regular intervals to ensure the cleaning power of the cleaning equipment. Thus, with the second end cover 1221 and the heating device 130 remaining stationary, only the first end cover 1221 needs to be opened to replace the roller brush body 121, making the operation convenient and the replacement efficiency high.

[0071] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the roller brush device 120 of this application embodiment also includes a roller brush side cover 123, which is used to connect with the floor brush body 110. The roller brush body 121 is rotatably connected to the roller brush side cover 123 through a first end cover 1221. The heating device 130 extends into the inner cavity 1211a of the roller brush body 121 through the second end cover 1221.

[0072] In a specific implementation, the roller brush side cover 123 is fixedly connected to the floor brush body 110, the first end cover 1221 is rotatably connected to the roller brush side cover 123, and the first end cover 1221 is fixedly connected to the roller brush body 121, thereby achieving a rotatable connection between the roller brush body 121 and the floor brush body, so that the roller brush body 121 rotates to contact the surface to be cleaned, and the surface to be cleaned is cleaned by rotation. The second end cover 1221 can be set to rotate with the roller brush body 121. In this case, the second end cover 1221 and the heating device 130 are rotatably connected to ensure that the heating device 130 is fixed and to avoid affecting the operation of the heating device 130. Alternatively, the second end cover 1221 can also be set to be fixedly connected to the heating device 130. In this case, the second end cover 1221 and the roller brush body 121 are rotatably connected. This application embodiment does not limit the connection method between the second end cover 1221 and the roller brush body 121, as long as it ensures that the heating device 130 always remains stationary.

[0073] See also some of the possible implementation methods. Figures 1 to 7 As shown, the floor brush body 110 of this embodiment includes: a floor brush housing 111 and a drive device 112. The floor brush housing 111 has a mounting portion 1112, which is located on the side where the second end cap 1221 of the cleaning chamber 1111 is located. The mounting portion 1112 has a mounting cavity 1112a and a communication port connecting the mounting cavity 1112a and the cleaning chamber 1111. The drive device 112 includes a drive assembly 1121 and an output component 1122. The drive assembly 1121 is disposed in the mounting cavity 1112a. The output component 1122 is connected to the drive assembly 1121 for rotation under the drive of the drive assembly 1121. The output component 1122 extends into the cleaning chamber 1111 from the communication port. The second end cap 1221 is fixedly connected to the output component 1122. The output component 1122 has an assembly channel 1122d extending axially along the roller brush body 121. The first end of the heating device 130 is fixedly connected to the mounting portion 1112. The second end of the heating device 130 extends into the inner side of the roller brush body 121 via the assembly channel 1122d.

[0074] Specifically, the drive assembly 1121 is fixed in the mounting cavity 1112a, the output component 1122 is fixedly connected to the second end cover 1221, the second end cover 1221 is fixedly connected to the roller brush body 121, the drive assembly 1121 drives the output component 1122 to rotate, and the output component 1122 drives the roller brush body 121 to rotate through the second end cover 1221, and the first end cover 1221 rotates relative to the roller brush side cover 123. The output component 1122 and the second end cover 1221 can be fixed together by welding or bolting, or by serrated engagement. For example, the second end cover 1221 has a connecting channel 1222a that runs through the axial direction of the brush body 121. The inner wall of the connecting channel 1222a and the outer surface of the output component 1122 are both provided with serrations. The output component 1122 extends into the connecting channel 1222a, so that the serrations on the inner wall of the connecting channel 1222a engage with the serrations on the outer surface of the output component 1122. When the output component 1122 rotates, it will drive the second end cover 1221 to rotate at the same time. Of course, the specific connection method between the output component 1122 and the second end cover 1221 is not limited in this embodiment, as long as the output component 1122 can drive the second end cover 1221 to rotate.

[0075] Furthermore, the first end of the heating device 130 is fixedly connected to the mounting part 1112 to ensure that the position of the heating device 130 remains unchanged and does not rotate with the brush body 121. The second end of the heating device 130 passes through the assembly channel 1122d of the output part 1122 and enters the inner cavity 1211a. The heating device 130 and the assembly channel 1122d are rotatably connected or the contact surfaces of the heating device 130 and the assembly channel 1122d are made smooth to avoid friction between the heating device 130 and the assembly channel 1122d when the output part 1122 rotates, which could damage the heating device 130.

[0076] See also some of the possible implementation methods. Figures 1 to 7 As shown, the output component 1122 of this application embodiment includes a driving part 1122a, a rotating support part 1122b, and a connecting part 1122c arranged sequentially along the axial direction of the roller brush device 120. The driving part 1122a is located in the mounting cavity 1112a and is used to connect with the driving assembly 1121. The connecting part 1122c is located in the cleaning cavity 1111 and is fixed to the inner side of the second end cover 1221. The driving device 112 includes a bearing 1123, which is sleeved on the rotating support part 1122b so that the output component 1122 can rotate relative to the brush housing 111.

[0077] It is understandable that the output component 1122 should be coaxially arranged with the roller brush body 121. When the drive part 1122a is connected to the drive assembly 1121 and the connecting part 1122c is connected to the connecting channel 1222a of the second end cover 1221, the rotating support part 1122b located in the middle of the output component 1122 will be in a suspended state, leaving a certain gap with the floor brush housing 111. Therefore, a bearing part 1123 is sleeved on the rotating support part 1122b so that the bearing part 1123 abuts against the floor brush housing 111. This can not only support the output component 1122 and prevent the output component 1122 from breaking in the middle, but also reduce the friction between the output component 1122 and the floor brush housing 111, ensuring that the output component 1122 can rotate relative to the floor brush housing 111. At the same time, it is beneficial to improve the rotation accuracy of the main shaft of the roller brush body 121.

[0078] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the drive assembly 1121 of this application embodiment includes: a power source, a mounting bracket 1121a, and a drive belt 1121b; the mounting bracket 1121a is disposed in the mounting cavity 1112a, and the bearing 1123 is disposed between the rotating support portion 1122b and the mounting bracket 1121a; the drive belt 1121b is sleeved on the drive portion 1122a and is located radially inside the mounting bracket 1121a, and the drive belt 1121b is configured to drive the output portion 1122 to rotate under the drive of the power source.

[0079] In some embodiments, the outer surface of the drive unit 1122a may be provided with serrations, and the inner side of the drive belt 1121b is provided with serrations that match those of the drive unit 1122a. The drive belt 1121b is connected to a power source and is sleeved on the drive unit 1122a, so that the drive unit 1122a and the drive belt 1121b mesh. The power source drives the drive belt 1121b to rotate, and the drive belt 1121b drives the output component 1122 to rotate through the drive unit 1122a. Since the drive belt 1121b has a certain elasticity, driving the output component 1122 to rotate through the drive belt 1121b helps to mitigate impact and vibration, ensuring the smooth rotation of the roller brush body 121, and reducing the noise during the operation of the cleaning equipment. At the same time, when the resistance experienced by the roller brush body 121 is too great, causing overload, slippage will occur between the drive unit 1122a and the drive belt 1121b, thereby preventing damage to other components in the cleaning equipment due to overload. In addition, the mounting bracket 1121a is set in the mounting cavity 1112a to support the output component 1122. The bearing component 1123 can be fixed on the mounting bracket 1121a by the rubber coating process to ensure the stability of the output component 1122.

[0080] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, the drive assembly 1121 of this application embodiment includes a pulley cover 1121c. The pulley cover 1121c is fixed to the side of the mounting bracket 1121a facing away from the cleaning chamber 1111. The pulley cover 1121c is provided with a mounting hole opposite to the assembly channel 1122d. The heating device 130 passes through the mounting hole and has a connection terminal. The connection terminal passes through the mounting hole to connect to the power supply.

[0081] In a specific implementation, the pulley cover 1121c is fixedly connected to the brush housing 111, and the mounting bracket 1121a is fixedly connected to the pulley cover 1121c. The first end of the heating device 130 has a connection terminal, which passes through the mounting hole and connects to the power supply. Simultaneously, the heating device 130 is fixedly connected to the pulley cover 1121c. The heating device 130 can be fixed to the pulley cover 1121c using an adhesive coating process. This embodiment does not limit the specific connection method between the heating device 130 and the pulley cover 1121c. Therefore, limiting the position of the heating device 130 and the mounting bracket 1121a by the pulley cover 1121c helps ensure the stable rotation of the roller brush body 121 and maintains the stability of the heating device 130.

[0082] See also some of the possible implementation methods. Figures 1 to 5 and Figure 7 As shown, the inner wall of the assembly channel 1122d in this embodiment of the application is provided with a first sealing groove 1122e, and the drive device 112 also includes a first sealing ring 1124. The first sealing ring 1124 is disposed in the first sealing groove 1122e to seal the gap between the heating device 130 and the output component 1122.

[0083] Understandably, the first sealing ring 1124 is fitted onto the heating device 130 and abuts against the inner wall of the first sealing groove 1122e to seal the gap between the heating device 130 and the assembly channel 1122d, ensuring that the inner cavity 1211a of the roller brush body 121 is a closed cavity. This helps to retain the heat generated by the heating device 130 in the inner cavity 1211a, allowing the temperature of the inner cavity 1211a to rise rapidly, thereby improving the drying efficiency of the roller brush body 121.

[0084] In addition, a second sealing ring 113 can be provided, and a second sealing groove is provided on the outer wall of the mounting bracket 1121a. The second sealing ring 113 is sleeved on the mounting bracket 1121a and located in the second sealing groove to seal the gap between the mounting bracket 1121a and the communication port, ensuring that the mounting cavity 1112a is a closed cavity. Of course, this embodiment of the application does not limit this, and the second sealing ring 113 and the second sealing groove can be selected and set according to the specific situation of the connection surface between the mounting bracket 1121a and the floor brush housing 111.

[0085] See also some of the possible implementation methods. Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the roller brush body 121 of this application embodiment includes a cylindrical body 1211 and a cleaning body 1212 sleeved on the outside of the cylindrical body 1211, wherein the cylindrical body 1211 is a metal part.

[0086] In this way, the metal parts have good thermal conductivity. By setting the cylinder 1211 as a metal part, when the heating device 130 starts heating, the cylinder 1211 can quickly transfer heat to the cleaning body 1212, thereby drying the cleaning body 1212 from the inside out. This helps to save the drying time of the cleaning body 1212 and improve the drying efficiency of the cleaning body 1212.

[0087] In addition, to ensure the stable and safe operation of other parts within the floor brush device 100, components such as the first end cover 1221, the second end cover 1221, the output component 1122, the pulley cover 1121c, and the drive belt 1121b, which are close to the heating device 130, can all be made of high-temperature resistant materials. This is to prevent damage to these components caused by the high-temperature environment inside the cleaning chamber 1111 when the heating device 130 is working, which would affect the service life of the cleaning equipment.

[0088] See also some of the possible implementation methods. Figure 2 , Figure 3 and Figure 7 As shown, the cylinder 1211 in this embodiment is an aluminum alloy part.

[0089] It should be noted that aluminum alloy has the characteristics of high strength, low density and good thermal conductivity. It can not only meet the structural strength requirements of the roller brush body 121 and ensure that the roller brush body 121 does not deform, but also ensure that heat is quickly transferred to the cleaning body 1212, saving drying time. At the same time, it can also help reduce the weight of the floor brush device 100 and improve the user experience of the cleaning equipment.

[0090] See also some of the possible implementation methods. Figures 1 to 7 As shown, the heating device 130 of this application embodiment includes at least one of a heating rod, a heating wire, and a heating tube.

[0091] In some embodiments, the heating device 130 can be any one of a heating rod, heating wire, or heating tube, as long as it can rapidly increase in temperature when powered on.

[0092] In practice, the first end cap 1221 and the second end cap 1221 can be fixed on the roller brush body 121 first, the drive belt 1121b can be pressed into the bearing on the mounting bracket 1121a, the first sealing ring 1124 can be fitted on the heating device 130, the output component 1122 can be fitted on the heating device 130, and finally the heating device 130 and the output component 1122 can be inserted together into the second end cap 1221 fixed on the roller brush body 121, thereby completing the assembly of the heating device 130.

[0093] See Figure 1 As shown in the illustration, this application embodiment also provides a cleaning device, which can be a sweeping machine, a floor scrubber, a robotic vacuum cleaner, or other cleaning equipment. The cleaning device may include any of the above-mentioned floor brush devices 100.

[0094] The structure and working principle of the floor brush device 100 have been described in detail in the above embodiments, and will not be repeated here.

[0095] In this embodiment of the application, by setting the above-mentioned floor brush device 100, after the user completes cleaning with the cleaning equipment, the floor brush device 100 can quickly dry the roller brush device 120, ensuring the dryness of the roller brush device 120, avoiding the growth of bacteria or the generation of odors, which is conducive to improving the cleaning performance of the cleaning equipment and extending the service life of the cleaning equipment.

[0096] See Figure 1 and Figure 2 As shown in the figure, this application embodiment also provides a cleaning system, including: a cleaning base station and the above-mentioned cleaning equipment, wherein the cleaning base station is at least configured to clean the roller brush device 120 of the cleaning equipment.

[0097] In this embodiment, the cleaning base station can clean the roller brush device 120 by spraying clean water or cleaning agent onto it to remove dirt and keep it clean. Simultaneously, a blower can be installed inside the cleaning base station. After cleaning, the heating device 130 starts heating while the blower simultaneously blows hot air onto the roller brush device 120. This way, the heating device 130 heats the roller brush device 120 from the inside out, and the blower heats it from the outside in, which further improves drying efficiency, saves drying time, and ensures the roller brush device 120 is completely dry, preventing localized dampness that could lead to bacterial growth or odor.

[0098] In summary, this application provides a floor brush device 100, a cleaning device, and a cleaning system. The floor brush device 100 includes a floor brush body 110, a roller brush device 120, and a heating device 130. The roller brush device 120 is rotatably disposed within the cleaning chamber 1111 of the floor brush body 110. The heating device 130 is disposed within the inner cavity 1211a of the roller brush device 120 and is used to heat the roller brush device 120 from the inside out. The cleaning system has a cleaning base station that can clean the roller brush device 120. After cleaning, the heating device 130 starts heating, thereby drying the roller brush device 120 from the inside out. In this way, even if the heating time of the heating device 130 is short, the part of the roller brush device 120 that remains damp is the part of the roller brush device 120 near the outer surface, and the moisture on it can evaporate and dry quickly. This helps to avoid the problem of deep dampness in the roller brush device 120 due to insufficient heating time, thereby ensuring that the roller brush device 120 can dry quickly and avoid the growth of bacteria or the generation of odors.
