Description

Technical Field

[0001] This invention relates to the technical fields of electric roller mops, floor scrubbers, vacuum cleaners, sweepers, etc., and specifically to a heating element, roller brush, and cleaning device. Background Technology

[0002] In cleaning devices such as electric roller mops, floor scrubbers, vacuum cleaners, and sweepers, roller brushes are one of the important technical means to improve cleaning performance. The basic working principle of a roller brush is that the roller brush rotates and contacts the surface to be cleaned, thus cleaning the surface through contact.

[0003] To improve cleaning performance, some solutions involve spraying cleaning fluid onto the roller brush or spraying it before and after the brush. The cleaning fluid can be a detergent, water, or other cleaning liquid. Wetting the roller brush or the surface being cleaned enhances cleaning performance. Another approach is to heat the cleaning fluid, using hot liquid to improve cleaning. However, there are currently many different solutions for generating and supplying this hot cleaning fluid, broadly categorized into two types: one uses electric or chemical energy to heat the cleaning fluid in a storage tank. The storage tank is connected to the roller brush via a pipeline, and the delivered cleaning fluid is sprayed onto the roller brush or the surface being cleaned. Spraying onto the roller brush generally involves two methods: spraying from the upper outer side of the roller brush, or diverting from the inside of the roller brush and seeping out from the cleaning section. This solution involves long-distance delivery, high energy consumption, and slow response. Furthermore, it raises the issue of high-pressure, high-temperature storage of the heated fluid in the storage tank. Ensuring safety is a major concern. Another solution proposed by the applicant is to directly heat the roller brush. The heated roller brush, upon contact with the cleaning fluid, indirectly heats the cleaning fluid, thus achieving a thermal cleaning effect. Compared to the original technology, this solution further shortens the heat energy transmission path, which is beneficial for energy saving and improving response performance. Safety issues are also better addressed. In addition, by setting up an electrical connection structure, the applicant eliminates the need for batteries at both ends or inside the roller brush cylinder. Instead, the cleaning device provides the power, increasing power supply capacity and ensuring battery life. Furthermore, it reduces the cost of replacing the roller brush, making the applicant's proposed roller brush practically applicable in daily life, rather than just theoretical. However, despite the numerous advantages of the proposed roller brush, the applicant hopes to further improve energy efficiency and response performance, which is crucial for reducing battery size, lowering costs, and enhancing practicality.

[0004] Therefore, the applicant continued its in-depth research and, through its unremitting efforts, proposed a roller brush equipped with a heating element that is in contact with and / or has a clearance fit with the outer periphery of the rotating cylinder. The heating element is used to heat the cleaning part of the rotating cylinder and / or supply the cleaning liquid to the cleaning part. This structure can further improve energy utilization efficiency and response performance. In the aforementioned solution, the heating element is the core component. When a flow channel needs to be set in the heating element, the flow channel requires a certain volume to be set, which results in the overall thickness of the heating element being still relatively large and the weight being relatively heavy. Therefore, it is difficult to design a more optimized heating element that can reduce the thickness and weight. Thus, the applicant, through research, proposed a heating element to solve the aforementioned problems, and also proposed a roller brush and cleaning device. Summary of the Invention

[0013] Preferably, the main sintering unit is equipped with a heating element.

[0014] Preferably, the main body is provided with a heating element and a heat insulation layer, which is used to conduct heat from the heating element to the main body.

[0015] Preferably, the system also includes a support frame, with the main body and the support frame distributed and connected in the front-to-back direction.

[0016] Preferably, the support has a cavity that mates with the main body. The upper edge of the cavity is sleeved with the upper edge of the main body along the axis of the rotating cylinder via a first sleeve structure, and the lower edge of the cavity is sleeved with the lower edge of the main body along the axis of the rotating cylinder via a second sleeve structure.

[0017] Preferably, the bracket is made of heat-insulating material, which serves as the heat insulation layer for the heating element, allowing the heat from the heating element to be conducted to the main body.

[0018] Preferably, the main body has multiple flow channels, and at least one of the two ends of the main body is provided with a transition groove for connecting adjacent flow channels; at least one of the two ends of the main body is provided with a liquid inlet assembly.

[0019] Preferably, a sealing element is provided at one end of the main body with a transition groove, and a transition flow channel is formed by the cooperation of the sealing element and the transition groove.

[0020] Preferably, it also includes a protrusion that can be fitted into the transition groove.

[0021] Preferably, the device also includes a support, with the main body and the support distributed and connected in the front-to-back direction. The liquid inlet assembly is provided with the protrusions on one side of the support and the other end of the support. The protrusions at the other end of the support can also be used as the other end of the main body to be fixed to the other end of the support.

[0022] Preferably, in the case of a separate liquid outlet, the outlet of the flow channel and the inlet of the liquid outlet are connected by a detachable connecting structure.

[0023] Preferably, the main body adopts an arc-shaped structure arranged circumferentially along the rotating cylinder, and a labyrinth flow channel is provided inside the main body. The labyrinth flow channel extends back and forth along the axis of the rotating cylinder starting from one end of the arc-shaped structure.

[0024] Preferably, the side of the cylinder facing the liquid outlet is provided with a recess extending along the axis of the rotating cylinder, and the liquid outlet is located in the recess.

[0025] Preferably, the liquid outlet is located on the side of the concave part that is in the opposite direction of rotation of the rotating cylinder.

[0026] Compared with the prior art, the present invention has the following advantages after adopting the above structure:

[0027] Because the surface of the heat-conducting component facing the rotating cylinder has a protrusion extending along the flow channel and protruding towards the rotating cylinder and / or protruding in the opposite direction, this design ensures the required thickness at the flow channel while reducing the thickness of other parts. This reduces the thickness, which in turn reduces the material and thus the weight of the heating element. Furthermore, the material reduction shortens the process of the heat-conducting component from cold to hot, and also reduces the amount of heat required to maintain its temperature. This helps to reduce heat waste and improve response performance.

[0028] Compared with the prior art, the present invention also proposes a roller brush, including a rotating cylinder and the heating part, wherein the heat-conducting element of the heating part is disposed in the circumference of the rotating cylinder, and the side of the heat-conducting element facing the rotating cylinder is in contact with and / or in clearance fit with the outer periphery of the rotating cylinder. The heat-conducting element is used to heat the cleaning part of the rotating cylinder and / or supply cleaning liquid to the cleaning part.

[0029] Compared with the prior art, the present invention has the following advantages after adopting the above structure:

[0030] The side of the heat-conducting component facing the rotating cylinder is in contact with and / or clearance fit with the outer periphery of the rotating cylinder. This heat-conducting component is used to heat the cleaning section of the rotating cylinder and / or the cleaning liquid supplied to the cleaning section. Therefore, the heat of the heat-conducting component can be transferred to the cleaning section and / or the cleaning liquid supplied to the cleaning section as quickly as possible, and is effectively used immediately after transfer. Heating the cleaning liquid supplied to the cleaning section refers to two situations: one is that the cleaning liquid in the cleaning section is heated when the already wetted cleaning section (e.g., wetted by the liquid outlet) passes through the heat-conducting component; the other is that the cleaning liquid is heated when it falls onto the cleaning section, and / or the cleaning liquid is heated before it falls onto the cleaning section. For example, the cleaning liquid first passes through the heat-conducting component and then is output to the cleaning section by the liquid outlet. With this design, the heated cleaning liquid immediately falls onto the cleaning section to participate in the subsequent cleaning work, resulting in high heat utilization and very little waste.

[0031] Since the heat-conducting component is in close contact with and / or has a clearance fit with the outer periphery of the rotating cylinder, and this heat-conducting component is used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part, the amount of heat required to reach a certain temperature is less, which can greatly improve the response performance. That is to say, after the heating part is turned on, in this invention, the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part can quickly reach the required working temperature, thus greatly improving the response performance.

[0032] Compared with the prior art, the present invention also proposes a cleaning device, which includes the aforementioned roller brush.

[0033] Compared with the prior art, the present invention has the following advantages when adopting the above structure: the cleaning device using the roller brush is conducive to further improving energy utilization efficiency and response performance, thereby enabling the same battery and the same operating temperature to extend the battery life.

Detailed Implementation

[0056] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0057] The present invention will now be described in further detail:

[0058] This disclosure provides a cleaning apparatus including the aforementioned roller brush, the roller brush being, for example, as shown in the example... Figure 1 As shown.

[0059] Cleaning devices include roller brush electric mops, vacuum cleaner heads, sweepers, floor scrubbers, etc. The cleaning devices referred to in this application generally refer to household or small cleaning devices. This is also a feature of the roller brush of this invention, which requires a small overall structural size to be suitable for small cleaning devices.

[0060] The roller brush exemplified in this disclosure includes a rotating cylinder 3. Of course, there can be multiple rotating cylinders 3, such as two or three. Regardless of the number, the design can be adapted or simply replicated from the given scheme. This invention also indicates that when multiple rotating cylinders 3 are present, at least one rotating cylinder 3 is provided with the heating element of this invention. When multiple rotating cylinders 3 need to be provided with heating elements, they can be cleverly arranged as follows: a heating element is provided between two adjacent rotating cylinders 3, meaning that two adjacent rotating cylinders 3 share a single heating element. In this case, the heating element can transfer heat to the corresponding rotating cylinder 3 from both sides. For example, heating elements 5 are provided on each side, or after the transition water tank 6 is heated, the transition water tank 6 transfers heat to the corresponding rotating cylinder 3 from both sides.

[0061] The cleaning part of the rotating cylinder 3 is generally the outermost layer, and its thickness is determined according to the cleaning performance or the needs of the surface being cleaned. By adopting the solution of the present invention, there is no need to modify the original structure of the rotating cylinder 3, so the existing rotating cylinder 3 can be used. For users, the replacement cost of the rotating cylinder 3 is almost not increased.

[0062] The use of cleaning liquids can be varied. For example, it can be applied to the surface being cleaned using other equipment, or it can be applied manually. When the heated cleaning part comes into contact with the wet surface, a good cleaning effect can be achieved. In this case, the object being heated is the cleaning part. Alternatively, the cleaning device can have other liquid supply structures, such as the liquid outlet disclosed herein. This liquid supply structure sprays the cleaning liquid onto the cleaning part, which is then heated. Even if the surface being cleaned is dry, a good cleaning effect can still be achieved under the action of the heated, wet cleaning part. Another example is the solution including a labyrinth flow channel and / or a transition water tank, as described in the following embodiments. Furthermore, the above situations can be combined in any way. For instance, there can be both manual watering and a liquid supply structure spraying and supplying the cleaning liquid, or there can be both a liquid supply structure spraying and supplying the cleaning liquid and a transition water tank, etc. These are not all listed here.

[0063] The water or water-related descriptions used in this disclosure do not refer to water alone, but are common terms. For example, a cleaning liquid tank is often called a clean water tank. Here, water refers to cleaning liquid. Cleaning liquid can be plain water, a mixture of water and cleaning agent, or a mixture of water and disinfectant.

[0064] This disclosure provides a heating element including a heat-conducting member 4, wherein the heat-conducting member 4 has a flow channel 14. Another type of heating element does not have a flow channel 14 in the heat-conducting member 4, for example... Figures 1 to 7 As shown, see Examples 1 to 6.

[0065] In some embodiments, such as Figure 16 , 19 As shown in Figures 20 and 21, the heat-conducting component 4 is provided with a flow channel 14, which is beneficial to improve energy utilization and reduce volume, but increases the thickness of the heat-conducting component 4. Therefore, this disclosure proposes that the surface of the heat-conducting component 4 facing the rotating cylinder 3 has a protrusion extending along the flow channel 14 and protruding in the direction of the rotating cylinder 3 and / or a protrusion protruding in the opposite direction at the flow channel 14. That is, there are three cases: the first is a protrusion extending along the flow channel 14 and protruding in the direction of the rotating cylinder 3, which can be called the first protrusion 33; the second is a protrusion extending along the flow channel 14 and protruding in the opposite direction of the direction of the rotating cylinder 3, which can be called the second protrusion 34; the third is a protrusion extending along the flow channel 14 and protruding in the direction of the rotating cylinder 3 and a protrusion protruding in the opposite direction, that is, it has both the first protrusion 33 and the second protrusion 34. Regardless of the type, both reduce the thickness and weight to some extent, especially the third type, which reduces the thickness the most. However, the first type makes it easier to set the heating element 5 on the back, while the second type makes it easier to make the surface of the heat-conducting element 4 facing the rotating cylinder 3 smoother.

[0066] In some embodiments, such as Figure 16 , 19 As shown in Figure 20, the first protrusion 33 is an arc-shaped protrusion. Of course, as... Figure 21 As shown, the second protrusion 34 can also be an arc-shaped protrusion. When the first protrusion 33 is an arc-shaped protrusion, since it is located on the side of the heat-conducting element 4 facing the rotating cylinder 3, setting it as an arc-shaped protrusion is beneficial for contact with the cleaning part of the rotating cylinder 3. On the one hand, it does not damage the cleaning part, and on the other hand, it causes less obstruction to the cleaning part.

[0067] In some embodiments, such as Figure 16 , 19 As shown in Figures 20 and 21, there is an arc-shaped recess 35 between adjacent protrusions, especially on the side of the heat-conducting component 4 facing the rotating cylinder 3. The arc-shaped recess 35 is easy to process, has little impact on the strength of the heat-conducting component 4, and is not prone to stress concentration. Furthermore, the arc-shaped recess 35 does not damage the cleaning part and has little obstruction to the cleaning part.

[0068] In some embodiments, such as Figures 1 to 20As shown, this disclosure provides a roller brush, including a rotating cylinder 3, and further including a scraping assembly and a heating part arranged sequentially along the rotation direction of the rotating cylinder 3. The heating part includes a heat-conducting element 4 and a heating element 5. The heating element 5 is used to heat the heat-conducting element 4. The side of the heat-conducting element 4 facing the rotating cylinder 3 is provided with an arc-shaped concave surface. The arc-shaped concave surface is used to fit and / or gap fit with the outer periphery of the rotating cylinder 3. The scraping assembly is used to discharge wastewater from the cleaning part. The heat-conducting element 4 is used to heat the cleaning part after being treated by the scraping assembly and / or the cleaning liquid supplied to the cleaning part.

[0069] In some embodiments, such as Figure 9 , 16 As shown in Figures 19, 20, and 21, the heat-conducting component 4 adopts an arc-shaped structure with an arc-shaped cross-section.

[0070] In some embodiments, such as Figure 2 , 3 As shown in Figures 10, 17, and 18, the system also includes a suction port 13, through which the wastewater is drawn away. This timely treatment of the wastewater helps prevent it from re-contaminating the cleaned surface. The suction port 13 is connected to a suction tube 32, through which the wastewater is drawn away in sequence.

[0071] In some embodiments, such as Figure 2 As shown, the scraping assembly is positioned to avoid the suction port 13. This design helps to prevent the scraping assembly from adversely affecting the flow cross-section of the suction port 13, allowing the suction port 13 to perform optimally. This avoidance of the suction port 13 does not require absolute avoidance, but rather refers to taking certain measures to reduce the obstruction of the suction port 13 by the scraping assembly. When the avoidance is minimal, i.e., the adverse effect on the suction port 13 is very small, then such avoidance is acceptable. Of course, complete avoidance is preferable.

[0072] In some embodiments, such as Figure 2 As shown, along the rotation direction of the rotating cylinder 3, the suction port 13 is in front and the scraping component is behind. With this design, the cleaning part has already been processed by the suction port 13 before passing through the scraping component, which helps to reduce the burden on the scraping component. Conversely, since the cleaning part has already been processed by the suction port 13, the scraping component can achieve a better cleaning effect on the cleaning part after subsequent processing.

[0073] In some embodiments, such as Figure 2 As shown, the suction port 13 is located on the rear side of the rotating cylinder 3, and the scraping component is located on the upper side of the suction port 13. With this design, after being processed by the scraping component, the sewage naturally flows downwards, and the suction port 13 can promptly suck up the sewage, thereby improving cleaning efficiency.

[0074] In some embodiments, such as Figure 2As shown, the scraping assembly uses a scraper blade 12. This design is relatively simple and reliable. The scraper blade 12 scrapes out the wastewater in a scraping motion, and in the axial direction of the rotating cylinder 3, it can thoroughly clean and discharge wastewater from the cleaning section, resulting in good performance.

[0075] In some embodiments, such as Figure 3 , 10 As shown in Figures 1 and 17, the system also includes a water pump 26. The rotating cylinder 3, the heating unit, and the water pump 26 are arranged sequentially from front to back. The water pump 26 is used to pump the cleaning liquid.

[0076] In some embodiments, such as Figure 3 , 10 As shown in Figure 17, the system also includes a motor 29, a rotating cylinder 3, a heating element, and the motor 29 arranged sequentially from front to back. A transmission assembly 30 is provided between the motor 29 and the rotating cylinder 3. The motor 29 drives the rotating cylinder 3 to rotate via the transmission assembly 30, which is located on the outer side of the other end of the heating element. This design facilitates a more compact structure.

[0077] In some embodiments, such as Figure 3 , 10 As shown in Figure 17, the water pump 26 and the motor 29 are arranged on the left and right sides, and the water pump 26 is biased towards the side where the heating part is located. This makes the structure more compact.

[0078] In some embodiments, such as Figure 3 , 10 As shown in Figure 17, the system also includes a roller brush holder 1. The roller brush holder 1 has a mounting part 31 on the rear side of the heating section, in which the water pump 26 and the motor 29 are both mounted. This facilitates better installation of the water pump 26 and the motor 29.

[0079] In some embodiments, such as Figure 10 , 17 As shown, one end of the heating element is connected to a liquid inlet assembly, which is connected to the water pump 26. This allows for a more compact structure. The liquid inlet assembly is, for example, the liquid inlet connector 16.

[0080] In some embodiments, such as Figure 10 , 17 As shown, the liquid inlet assembly has a rearward-facing connector that communicates with the output end of the water pump 26. This facilitates a more compact structure. For example, the connector is connected to the output end of the water pump 26 via a connecting pipe.

[0081] In some embodiments, such as Figures 1 to 18As shown, the roller brush includes a separable heating section and a liquid outlet. The heating section includes a heat-conducting element 4 and a heating element 5. Both the heat-conducting element 4 and the liquid outlet are circumferentially arranged around the outer periphery of the rotating cylinder 3. The heating element 5 is thermally connected to the heat-conducting element 4. The heat-conducting element 4 is in contact with and / or has a clearance fit with the outer periphery of the rotating cylinder 3. The heat-conducting element 4 is used to heat the cleaning section of the rotating cylinder 3 and / or supply the cleaning liquid to the cleaning section. Along the rotation direction of the rotating cylinder 3, the liquid outlet is located in front of and / or behind the heat-conducting element 4, and the liquid outlet is used to output the cleaning liquid. With this design, once a blockage occurs, only the liquid outlet needs to be cleaned, for example... Figure 4 As shown, the roller brush has a transition water tank 6, which has a heating part and a liquid outlet that can be separated from each other. When it is blocked, the transition water tank 6 can be removed and the liquid outlet 7 can be cleaned. There is no need to clean the heating part. When the blockage requires replacement, the heating part can be reused.

[0082] like Figures 8 to 18 As shown, this disclosure provides another type of roller brush, which differs from the roller brush described above in that the transition water tank 6 is eliminated; that is, the function of the heating section is not provided by the transition water tank 6. With this design, if clogging occurs, only the liquid outlet needs to be cleaned, for example... Figure 8 , 9 As shown, the liquid outlet is connected to the lower side of the upper cover 2. It can be designed so that when the upper cover 2 is removed, the upper cover 2 and the liquid outlet are removed together. The liquid outlet can be detachably connected to the heat-conducting component 4, or they can be separate. When the liquid outlet and the heat-conducting component 4 are detachably connected, it can be designed so that when the upper cover 2 is removed, the upper cover 2 and the liquid outlet are removed together, while the liquid outlet is separated from the heat-conducting component 4 through the detachable connection. In this way, the heat-conducting component 4 remains on the roller brush and is not removed. For example, as shown... Figure 8 , 9 As shown in Figure 11, a latch 27 is provided on the front edge of the liquid outlet, which is detachably engaged with the heating element. The supply of cleaning liquid to the liquid outlet can be either direct supply from the supply assembly, or the supply assembly can first supply the cleaning liquid to the heating element 5 and / or the heat-conducting element 4, where it is heated before being supplied to the liquid outlet for output. Figure 9 , 13 As shown in Figure 15, the main body 17 is provided with a flow channel. The outlet of the flow channel is connected to the inlet of the liquid outlet through a detachable connecting pipe 28. The liquid supply component delivers cleaning liquid into the flow channel through the liquid inlet 15. After removing the liquid outlet, the liquid outlet 7 can be cleaned without cleaning the heating element. When blockage necessitates replacement, only the liquid outlet needs to be replaced, while the heating element remains on the roller brush holder 1 without any operation or replacement. In other words, the heating element can be reused.

[0083] Of course, the liquid outlet 7 can also be integrated, for example, as shown in the example. Figure 19As shown, this disclosure provides another heating element, wherein the liquid outlet 7 is integrated into the main body 17 of the heating element.

[0084] In some embodiments, the liquid outlet component is provided with a liquid outlet channel 14, and each liquid outlet hole 7 is connected to the liquid outlet channel 14.

[0085] In some embodiments, the liquid outlet channel 14 is preferably a straight channel, which can be parallel to or inclined to the axial direction of the rotating cylinder 3. The fact that the main body or transition tank has a liquid outlet channel 14 arranged along the axial direction does not require that the liquid outlet channel 14 be parallel to the axial direction. Rather, it requires that each liquid outlet hole 7 can cover the cleaning part of the rotating cylinder 3, thus requiring the liquid outlet channel 14 to be able to deliver liquid to each liquid outlet hole 7.

[0086] In some embodiments, to facilitate production and assembly, the following design is made, such as... Figure 10 , 12 As shown in Figures 13, 14, and 15, the heating unit includes a liquid inlet connector 16, a support 18, and a main body 17 extending along the axis of the rotating cylinder 3. The main body 17 and the support 18 are distributed and connected in the front-rear direction. A flow channel extending along the axis of the rotating cylinder 3 is provided inside the main body 17. The liquid inlet connector 16 is connected to one end of the main body 17 and communicates with the flow channel. The liquid inlet connector 16 is used to connect to the liquid supply assembly. A liquid outlet 23 is provided on the side of the liquid inlet connector 16 located on one side of the support 18. The liquid outlet 23 communicating with the flow channel means that the liquid outlet 23 communicates with the inlet of the flow channel. Using the support 18, this design allows for a further reduction in the thickness of the main body 17, thereby improving energy utilization.

[0087] In some embodiments, the assembly sequence of the heating element may be as follows: the main body 17 is inserted along one end of the bracket 18, thus the main body 17 and the bracket 18 are sleeved along the axial direction of the rotating cylinder 3; then the liquid inlet connector 16 is connected to one end of the bracket 18 and / or the liquid inlet connector 16 is connected to one end of the main body 17, for example... Figure 14As shown, the liquid inlet connector 16 has two screw through holes 24, and correspondingly, one end of the main body 17 also has two threaded holes 25. Screws connect and fix the liquid inlet connector 16 to one end of the main body 17 through the screw through holes 24 and threaded holes 25. Simultaneously, the side of the liquid inlet connector 16 located on one side of the bracket 18 closes the opening at one end of the bracket 18. A sealing gasket is provided on the side of the liquid inlet connector 16 located on one side of the bracket 18, and the side of the liquid inlet connector 16 located on one side of the bracket 18 is tightly pressed and fixed together with the end face of one end of the bracket 18 through the sealing gasket. The other end of the bracket 18 can also be provided with screw through holes 24, and correspondingly, the other end of the main body 17 also has threaded holes 25. Screws connect and fix the other end of the main body 17 to the other end of the bracket 18 more effectively through the screw through holes 24 and threaded holes 25. Figure 12 , 13 As shown, the bracket 18 has a cavity, and the upper and lower edges of the cavity are respectively fitted with the upper and lower edges of the main body 17 via a tongue-and-groove joint structure. In this example, for instance... Figure 16 As shown, the groove of the concave-convex sleeve structure is provided on the upper and lower edges of the main body 17, and the upper and lower edges of the cavity are respectively provided with the protrusions 19 of the concave-convex sleeve structure. This structural design makes assembly very convenient, and in addition, it provides more reliable support for the main body 17.

[0088] In some embodiments, the flow channels in the main body 17 are not a single channel, but multiple channels, which facilitates the formation of a maze-like flow channel, such as... Figure 13 , 15 As shown, the main body 17 has four flow channels arranged in parallel to form a serpentine labyrinth flow channel, and the outlet of the last flow channel is connected to the liquid outlet through the connecting pipe 28. To simplify manufacturing, transition grooves 20 are machined at both ends of the main body 17. These transition grooves 20 are used to connect adjacent flow channels. For the closure of the transition grooves 20, for example, a sealing element can be provided at each end of the main body 17. For example, a protrusion 21 as a sealing element can be provided at one side of the liquid inlet connector 16 located on the other end of the support 18. The transition flow channel is formed by the cooperation of the protrusion 21 and the transition groove 20. The protrusion 21 at the other end of the support 18 can also be used to fix the other end of the main body 17 to the other end of the support 18 after the main body 17 and the support 18 are sleeved together, which greatly facilitates the manufacturing process.

[0089] In some embodiments, such as Figure 19 , 20 As shown, the main body 17 adopts an arc-shaped structure arranged circumferentially along the rotating cylinder 3. The main body 17 is provided with a labyrinth flow channel, which extends back and forth along the axis of the rotating cylinder from one end of the arc-shaped structure, for example, forming the serpentine labyrinth flow channel.

[0090] In some embodiments, such as Figure 9 , 16As shown in Figures 19 and 20, the main body 17 can be made of profiles, which can be metallic or non-metallic materials, preferably metallic materials, such as aluminum alloy profiles or stainless steel profiles. Taking aluminum alloy profiles as an example, these profiles can be obtained through existing extrusion processes. Specifically, an elongated aluminum alloy profile is first formed using an extrusion die. This die has a structure that allows for the formation of a flow channel along the length of the elongated aluminum alloy profile during the extrusion process. After obtaining the elongated aluminum alloy profile, it is then cut to a certain length to obtain a single main body 17. Multiple main bodies 17 can be obtained from one elongated aluminum alloy profile through cutting. Next, the two end faces of each main body 17 are machined to obtain the transition groove 20. Thus, the main body 17 used as an assembly component is completed. The assembly component's main body 17 is then assembled to obtain the complete heating section. The aforementioned solution greatly simplifies manufacturing and significantly improves production efficiency while reducing production costs. Due to the characteristics of the field of cleaning devices in which this disclosure pertains, namely the requirement that the structural size should be as small as possible and the cost should not be too high, the aforementioned solution provides extremely important technical support for the application of the relevant solutions of this disclosure in the field of cleaning devices.

[0091] In some embodiments, such as Figure 14 As shown, the main body 17 is also provided with a heating element 5, which is thermally connected to the main body 17. For example, the heating element 5 is provided on the back of the main body 17. This is beneficial to protect the heating element 5 and simplifies the manufacturing process.

[0092] In some embodiments, the back of the main body 17 is provided with a mounting groove, and the heating element 5 is provided in the mounting groove. This is beneficial to reducing the overall thickness of the component formed after the main body 17 and the heating element 5 are connected, and also to forming a certain wrapping around the heating element 5, so that more heat is conducted to the main body 17.

[0093] In some embodiments, such as Figure 14 As shown, the heating element 5 is sintered on the back of the main body 17. For example, an electric heating material is coated on the back of the main body 17 and sintered. In this way, the heating element 5 is more firmly bonded to the main body 17 and forms a whole. This design helps to reduce the loss of heat conduction and also helps to make the overall thickness of the component formed after the main body 17 and the heating element 5 are connected smaller.

[0094] In some embodiments, a heat insulation layer is provided on the back side of the main body 17, which is used to conduct heat from the heating element 5 to the main body 17. This is beneficial for energy saving, improving the utilization rate of thermal energy, and reducing waste.

[0095] In some embodiments, a heat insulation layer can be separately provided on the back of the main body 17, or the bracket 18 can be used as the heat insulation layer of the heating element 5. The bracket 18 can be made of heat insulation material, which can further simplify the structure. However, if a separate heat insulation layer is used, it is convenient to select materials for the bracket 18 without being limited to using heat insulation material. However, the assembly will be one step more, that is, a separate heat insulation layer needs to be provided.

[0096] The following examples illustrate the roller brush of this disclosure:

[0097] Example 1:

[0098] This disclosure discloses a roller brush comprising a rotating cylinder 3, with a heating element circumferentially arranged on the outer periphery of the rotating cylinder 3. The heating element is in contact with the outer periphery of the rotating cylinder 3 and is used to heat the cleaning part of the rotating cylinder 3. In this way, the heat generated by the heating element is directly in contact with and transferred to the cleaning part, with zero heat transfer distance. Moreover, the cleaning part is immediately used for cleaning after being heated, resulting in high efficiency, reduced heat waste, and improved effective heat utilization.

[0099] The heating section includes a heat-conducting element 4 and a heating element 5. The heat-conducting element 4 is arranged circumferentially around the outer periphery of the rotating cylinder 3, and the heating element 5 is connected to the heat-conducting element 4. This design facilitates heat transfer through the heat-conducting element 4. On the one hand, the heating element 5 involves power supply issues, and the aforementioned design allows for easy arrangement of its structure. On the other hand, the heat-conducting element 4 enables simple and efficient heat transfer to be more comprehensive, thus ensuring the heated area of ​​the cleaning section. It also helps reduce the number of heating elements 5 required, avoiding excessive weight increase.

[0100] It also includes a roller brush holder 1, which has a first opening 9 for detachably mounting the rotating cylinder 3, and a heating element is installed inside the first opening 9. This design does not affect the replacement of the rotating cylinder 3, and after replacing the rotating cylinder 3, it is no longer necessary to adjust the distance between the heating element and the rotating cylinder 3, that is, it can be used directly after replacement, which greatly facilitates the user.

[0101] Preferred, such as Figure 1 , 2 As shown in Figure 3, the roller brush holder 1 is detachably connected to the upper cover 2. The heating element is located below the upper cover 2. After removing the upper cover 2, the heating element can be seen. In addition, after removing the upper cover 2, the rotating cylinder 3 can also be removed in the vertical direction for cleaning or replacement. That is, the upper cover 2 also serves as a limiting mounting component for the rotating cylinder 3. This design greatly facilitates the manufacturing of this invention and also makes it convenient for everyday users.

[0102] The heating element of the heating section is provided on the side of the heating section that is in contact with the outer periphery of the rotating cylinder 3.

[0103] The heating element includes a continuous heat-conducting element 4 arranged along the axial direction and a discontinuous heating element 5. The heat-conducting element 4 is on the outer side, and the heating element 5 is on the inner side. The heat-conducting element 4 separates the heating element 5 from the rotating cylinder 3. In this way, on the one hand, the arrangement and number of heating elements 5 are simplified, and on the other hand, the heat-conducting element 4 separates the heating element 5 from the rotating cylinder 3, which helps to protect the heating element 5 and extend its service life.

[0104] The heating element is continuously arranged along the axial direction of the rotating cylinder 3. This design ensures that the cleaning section is heated evenly, which is beneficial to cleaning performance.

[0105] It also includes a heat insulation structure, which is used to transfer most of the heat generated by the heating element to the cleaning element. For example, the heat insulation structure is installed in the heat insulation layer at the rear and around the heating element 5. In this way, the heat from the heating element 5 is mainly transferred to the front, that is, mainly to the heat conduction element 4, which then transfers the heat to the cleaning element. This design helps reduce waste and improve heat utilization.

[0106] The heating section facing the rotating cylinder 3 includes an arc-shaped structure arranged around the rotation direction of the rotating cylinder 3. In this example, the heat-conducting element 4 is an arc-shaped structure, that is, the heat-conducting element 4 is a concave arc-shaped plate. With this design, the concave arc-shaped plate matches the outer peripheral surface of the cleaning section, which on the one hand facilitates the smooth rotation of the cleaning section, and on the other hand facilitates the good fit between the concave arc-shaped plate and the cleaning section, thereby improving the heat transfer efficiency.

[0107] In this example, the transition water tank 6 is not included. The above structure can be referenced in the appendix. Figure 1 , 2 As shown in Figures 4 and 5, Figure 2 , 4 This example can be constructed by omitting the other structures of the transition water tank 6 in section 5.

[0108] In this example, the liquid outlet and the heating unit share a frame. The frame has a front panel with liquid outlet holes 7. Each liquid outlet hole 7 is connected to the liquid supply assembly, while the heating unit assembly is detachably connected to the frame.

[0109] Example 2:

[0110] Compared with Example 1, Example 2 differs in that the heating part and the outer circumference of the rotating cylinder 3 are fitted with a clearance. The technical effect of this setting is that, on the one hand, the rotational resistance of the rotating cylinder 3 is reduced, on the other hand, wear is reduced, and on the other hand, the squeezing of the cleaning part is reduced, which helps to avoid the loss of cleaning liquid caused by the squeezing out of the cleaning part.

[0111] Example 3:

[0112] Compared with Example 1, Example 3 differs in that the heating part and the outer periphery of the rotating cylinder 3 are both in contact and with a gap. The advantage of this arrangement is that it provides great flexibility, and the contact and gap fit can be flexibly set according to the characteristics of the cleaning part, thereby further optimizing the structure.

[0113] Example 4:

[0114] Compared with Examples 1, 2, and 3, Example 4 differs in that a transition water tank 6 is added, and the heating unit is used to heat the cleaning liquid supplied to the cleaning unit. In this case, the heating unit and the outer periphery of the rotating cylinder 3 are preferably fitted with a clearance.

[0115] When the transition water tank 6 is added, the structure is as follows: a heating part is provided on the circumference of the outer periphery of the rotating cylinder 3. The heating part is fitted with the outer periphery of the rotating cylinder 3 with a clearance. The heating part includes the transition water tank 6. The heating element 5 of the heating part is located in the transition water tank 6. The transition water tank 6 is used to connect to a water source. The heating element 5 is used to heat the cleaning liquid in the transition water tank 6. The heated cleaning liquid flows to the cleaning part. In this way, the cleaning part is also heated by the heat brought by the cleaning liquid.

[0116] The transition water tank 6 has a small capacity, which is smaller than the capacity of the water source.

[0117] Preferably, the small capacity is within six times, including six times, the volume of the cleaning liquid supply flow rate per unit time. The supply amount of cleaning liquid per unit time is set according to the cleaning needs. Generally speaking, reaching or exceeding this supply amount is beneficial to better cleaning performance. However, if the capacity of the transition water tank 6 is not limited, it will bring disadvantages. Therefore, the capacity of the transition water tank 6 is also important. As stated in this invention, "the transition water tank 6 adopts a small capacity, which is smaller than the capacity of the water source." With the aforementioned design, the required amount for cleaning can be better matched, while balancing energy consumption. In addition, it is also more conducive to controlling the opening and closing of the heating element 5 by the control program. This is because the larger the capacity of the transition water tank 6, the more difficult it is to control the stability of the working temperature during dynamic use. When the capacity of the transition water tank 6 is small, but the supply amount can still be maintained, then the balance point at this time is more conducive to balancing the three factors of energy consumption, temperature stability control, and cleaning performance.

[0118] The transition water tank 6 is equipped with a labyrinth heating channel, which is used to rapidly heat the cleaning liquid flowing through it by the heating element 5 within a short time. In this example, as... Figure 7 As shown, the labyrinth heating channel of the transition water tank 6 is set as a V-shaped labyrinth heating channel. In addition, in order to better match the rotating cylinder 3, the overall shape of the transition water tank 6 is also roughly V-shaped.

[0119] In this example, as Figure 7As shown, the cleaning liquid in the V-shaped labyrinth heating channel flows in from the upper right end and then flows out along the V-shape to the upper left end. This design lengthens the flow distance, allowing the cleaning liquid more time to absorb the heat generated by the heating element 5. Furthermore, the upward flow at the outlet side facilitates heat removal from the heating element 5, as heat tends to rise more easily. Additionally, the V-shape brings the left and right channels closer together, preheating the cleaning liquid in the right-side downward flow channel when the heating element 5 is heating. This allows the liquid to reach a higher temperature more quickly when flowing upwards at the outlet side, shortening the heating time. Moreover, the V-shaped labyrinth heating channel makes the overall structure very compact. If further shortening of the heating time is required, the heating element 5 can also be installed in the right-side downward flow channel.

[0120] The above design achieves the following technical effects: First, the cleaning liquid in the transition water tank 6 is used in the cleaning unit immediately after heating, eliminating the need for long-distance transport and greatly reducing waste. Furthermore, it avoids the safety hazards associated with long-distance transport. Second, as the purpose of this invention is clear, the amount of cleaning liquid in the transition water tank 6 is not large, so the heat generated by the heating element 5 is sufficient to heat the cleaning liquid in the transition water tank 6 in a short time, allowing for rapid entry into normal working condition with a very fast response. Third, when work stops, the amount of cleaning liquid remaining in the transition water tank 6 is small, resulting in minimal heat waste. Additionally, when… When stopping work, it can be turned off in advance. For example, if the working time is set to 10 minutes, the heating element 5 can be turned off in advance when the 10-minute working time is reached. This allows the last heated cleaning liquid to be used for cleaning the surface being cleaned, so that the heated cleaning liquid is not left unused. Of course, other measures can also be adopted, such as turning off the heating element 5 in advance, but allowing the rotating cylinder 3 to continue rotating, while the hot cleaning liquid remaining in the transition water tank 6 continues to be supplied. In this way, the rotating cylinder 3 can clean itself, thereby utilizing the heat of the cleaning liquid remaining in the transition water tank 6. Therefore, taking this measure can further reduce waste.

[0121] Example 5:

[0122] like Figure 2 , 3 As shown in 4, 5, 6, and 7, Figure 7The middle arrow indicates the flow direction of the cleaning liquid. The difference between Example 5 and Example 4 is that not only is a transition water tank 6 added, but a heating element is also used to heat the cleaning part of the rotating cylinder 3. Specifically, in this example, the heating element 5 is arranged circumferentially around the outer periphery of the rotating cylinder 3. While heating the cleaning liquid, the heating element 5 also includes a heat-conducting element 4, which is arranged circumferentially around the outer periphery of the rotating cylinder 3. The heating element 5 heats the cleaning liquid and also heats the cleaning part of the rotating cylinder 3 through the heat-conducting element 4.

[0123] The technical advantages of this design are as follows: First, the heat generated by the heating element 5 in the front-to-back direction can be applied to the cleaning section more quickly. That is, the front side of the heating element 5 is the cleaning section, and the rear side is the cleaning liquid. Therefore, the heat emitted by the heating element 5 in the front-to-back direction is utilized more efficiently. This is because the front side of the heating element 5 directly heats the cleaning section, eliminating the need for the cleaning liquid in the transition water tank 6 to carry heat before heating the cleaning section. This reduces one heat conversion step. Furthermore, the direct heating of the cleaning section by the front side of the heating element 5 also improves structural compactness. Since the rear side of the heating element 5 cannot directly heat the cleaning section, the heat is carried by the cleaning liquid in the transition water tank 6 before being superimposed on the preheated cleaning section by the front side of the heating element 5. Thus, the heat emitted by the heating element 5 is utilized more efficiently. Because the heat is utilized more efficiently, it greatly helps to shorten the heating time, allowing the working condition to be achieved in a shorter time. First, it improves the temperature; second, while achieving more efficient heat utilization, it also helps to further improve the structural compactness, thereby further reducing the thickness of the transition tank 6; third, when designing the V-shaped labyrinth heating channel, it is possible to achieve faster heating by only setting the heating element 5 in the bottom-up flow channel on the left side of the V-shaped labyrinth heating channel, without setting the heating element 5 in both the left and right sides of the V-shaped labyrinth heating channel, making the overall structure more optimized. At the same time, this also avoids the heat waste caused by setting the heating element 5 in both the left and right sides of the V-shaped labyrinth heating channel. The reason is that if the heating element 5 is set in the bottom-up flow channel on the right side of the V-shaped labyrinth heating channel, it will inevitably increase the heat transfer of the heating element 5 to the right side. However, due to the limited heat absorption rate of the cleaning liquid, it cannot be absorbed and carried away in time, resulting in heat loss. The above solution avoids this situation.

[0124] In this example, as Figure 5 , 6As shown, the transition water tank 6 has a second opening 10 on the side facing the rotating cylinder 3, allowing the heating element 5 to be exposed. This reduces the obstruction between the heating element 5 and the heat-conducting element 4, making it easier for the heating element 5 to transfer heat through the heat-conducting element 4. This design allows the heating element 5 to be closer to the cleaning section, and also allows the transition water tank 6 to be closer to the cleaning section. This enables the heated cleaning liquid to be transported to the cleaning section over a shorter distance, and also allows the heated cleaning section and the heated cleaning liquid to meet more quickly, thereby minimizing heat loss. This allows for better maintenance of the temperature of the cleaning section with a smaller input heating power, which further improves energy utilization and response performance.

[0125] In this example, as Figure 4 , 5 As shown in Figure 6, to ensure a more uniform output of the heated cleaning liquid, multiple outlet holes 7 are sequentially arranged along the axial direction of the rotating cylinder 3. These outlet holes 7 are connected to the outlet end of the V-shaped labyrinth heating channel via multiple connecting holes 8. Therefore, the multiple outlet holes 7 are located on the upper side of the heat-conducting component 4. The inlet end 11 of the V-shaped labyrinth heating channel is connected to a water source via a pipeline, i.e., connected to the cleaning liquid tank. A water pump can be installed to increase the delivery pressure of the cleaning liquid. Alternatively, the heating component 5 can be shut off promptly by detecting the water level in the cleaning liquid tank and / or the presence of cleaning liquid in the pipeline, thereby achieving higher safety performance, such as anti-dry-burning performance.

[0126] Other solutions are also possible for simultaneous heating. For example, while heating the cleaning liquid, the heating element 5 can directly heat the cleaning part of the rotating cylinder 3. Or, while heating the cleaning liquid, the transition water tank 6 can also be heated after the cleaning liquid is heated, so the cleaning part of the rotating cylinder 3 can be heated through the heated transition water tank 6.

[0127] Example 6:

[0128] The difference between Example 6 and Example 5 is that Example 6 also includes a scraper 12. The scraper 12 scrapes the cleaning part, which scrapes off the sewage and dirt on the cleaning part together, and then sucks it away by the suction port 13 near the scraper 12. This is also a working characteristic of the floor scrubber. In Embodiment Six, along the circumferential rotation of the rotating cylinder 3, the transition water tank 6 is located behind the scraper 12. That is, the cleaning section scrapes the dirt first, and then the transition water tank 6 supplies heat. The heat includes the heat that heats the cleaning section passing through the transition water tank 6 and the heat carried by the heated cleaning liquid when it falls onto the cleaning section from the outlet 7. This allows for more efficient use of heat and avoids wasting heat on the contaminated part of the cleaning section (the contaminated part of the cleaning section). This is because the cleaning section consumes heat after cleaning the surface. If the wastewater is not removed in time, the part of the cleaning section where the wastewater is located (the contaminated part of the cleaning section) will reabsorb heat, and the contaminated part of the cleaning section is not conducive to cleaning. Therefore, through the above design, the heat is used more effectively, thereby further reducing waste.

[0129] Example 7:

[0130] Example 7 differs from the above examples in that there can be multiple heating units, each arranged along the axial direction of the rotating cylinder 3, with the axial length of each heating unit approximately equal to that of the cleaning unit. Furthermore, the heating units are arranged sequentially along the circumference of the rotating cylinder 3. In other words, compared to... Figure 2 The structure shown in Embodiment 7 is a heating element. In Embodiment 7, at least one heating element is added sequentially along the circumference of the rotating cylinder 3, forming a structure with two heating elements. This structure in Embodiment 7 is advantageous for reaching the required temperature more quickly, and if necessary, it can reach even higher temperatures. However, the structure is relatively large and the energy consumption is high, which exceeds the requirements of ordinary cleaning. Embodiment 7 is more suitable for some occasions that require higher temperatures.

[0131] Example 8:

[0132] The difference between Embodiment 8 and the above embodiments is that it also includes a temperature sensor, which is used to detect the temperature of the heating part and / or the temperature of the cleaning part and / or the temperature of the cleaning liquid supplied to the cleaning part and / or the temperature of the surface being cleaned.

[0133] By setting up a temperature sensor, the technical benefits are twofold: firstly, it provides a structural foundation for more intelligent heating control, and combined with the control program, it helps to further refine energy consumption control; secondly, it can further improve safety, adding an extra layer of protection.

[0134] Example 9:

[0135] like Figures 8 to 15As shown, in this example, the transition water tank 6 is omitted, and there is no concept of a water tank. The heating unit has a main body 17 or a main body 17 with a flow channel. This main body 17 also serves as a heat conductor 4. The cleaning liquid flows into the flow channel from one end of the main body 17, that is, the liquid inlet connector 16 is connected to one end of the main body 17. The liquid inlet connector 16 communicates with the flow channel and is used to connect the liquid supply assembly. This significantly reduces the overall volume of the heating unit, and since the liquid enters from one end, it eliminates the need for... Figure 3 As shown, liquid enters from the inlet end 11 located at the top center, which also helps to reduce the dimension in the height direction. The aforementioned measures help to reduce the volume of the roller brush or free up more space to install other structures, such as... Figure 10 As shown, because more installation space is freed up, the water pump 26 can also be integrated into the roller brush. In this example, the water pump 26 is located on the side where the liquid inlet connector 16 is located.

[0136] In this example, the main body 17 not only heats the cleaning liquid, but also, due to its own thermal conductivity, can be used to directly heat the cleaning section. That is, the main body 17 also functions as a heat conductor 4, thus accelerating the heating of the cleaning section. This design not only provides a fast response, but also ensures high energy efficiency because the heat is primarily used for the cleaning section, as it is generated through both heating the cleaning liquid and directly heating the cleaning section via the main body 17.

[0137] Example 10:

[0138] Compared to Example 9, for example Figure 11 As shown, the liquid outlet has a recess 22 extending along the axis of the rotating cylinder 3 on one side, and a liquid outlet hole 7 is provided in the recess 22. With this design, dirt is not easily allowed to enter the liquid outlet hole 7, and the liquid outlet is kept smooth.

[0139] In some embodiments, such as Figure 11 As shown, the rotating arrow indicates the rotation direction of the rotating cylinder 3, and the liquid outlet 7 is located on the side of the recess 22 opposite to the rotation direction of the rotating cylinder 3. With this design, the anti-clogging performance is better. In addition, with the aforementioned design, the cleaning part will not be tightly squeezed at the liquid outlet 7, thus facilitating smoother liquid discharge.

[0140] Example 11:

[0141] Compared to Example 10, Example 11 is, for example... Figure 19 , 20As shown, the difference lies in the inclusion of a scraper 12. The scraper 12 serves as the scraping component, and both the liquid outlet 7 and the scraper 12 are integrated into the heat-conducting component 4. In this example, they are integrated into the main body 17. Specifically, the liquid outlet 7 is located near the upper edge of the main body 17, and the scraper 12 is located near the lower edge of the main body 17. The scraper 12 scrapes away the wastewater and dirt from the cleaning area, which is then sucked away by the suction port 13 near the scraper 12. Due to its integrated design, the scraper 12 can also transfer some heat, resulting in a hot scraper 12. A hot scraper 12 provides a better cleaning effect when cleaning the area compared to a cold scraper 12.

[0142] In some embodiments, such as Figure 19 , 20 As shown, the scraper 12 and the heat-conducting component 4 are integrated, which makes it easier to conduct heat to the scraper 12, reducing heat waste. In addition, it helps to simplify the structure and facilitates production and manufacturing.

[0143] In each embodiment, the heating element 5 adopts an electric heating structure, such as PTC heating, film heating, printed heating element, etc. Any heating element 5 that is suitable for the present invention can be applied to the present invention.

[0144] When understanding this invention, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that's understood, so I won't go into details here.

[0145] The above description is merely an illustrative embodiment of the present invention. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of the present invention are included within the scope of protection of the present invention.
