Description

Technical Field

[0001] The present invention relates to the technical fields of electric mops with roller brushes, floor scrubbers, vacuum cleaners, sweepers, and the like, and in particular to a heating part, a roller brush, and a cleaning device. Background Art

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

[0003] In order to improve the cleaning performance, it has been proposed to spray cleaning liquid on the roller brush or before and after the roller brush. The cleaning liquid can be detergent, water or other cleaning liquids. In this way, the cleaning performance is improved by wetting the roller brush or the surface to be cleaned. In addition, in order to further improve the cleaning performance, it has been proposed to heat the cleaning liquid, that is, to use hot cleaning liquid to improve the cleaning performance. However, there are currently many different solutions for how to produce and supply hot cleaning liquid. They can be roughly divided into two types: one is to use electric heat or chemical energy to heat the cleaning liquid in the storage tank. The storage tank and the roller brush are connected by a pipeline, and the transported cleaning liquid is sprayed on the roller brush or the surface to be cleaned. There are roughly two types of spraying on the roller brush. One is to spray on the upper side of the outside of the roller brush, and the other is to divert from the inside of the roller brush and then seep out from the cleaning part of the roller brush. This solution has a long transportation distance, high energy consumption, and slow response. In addition, it involves the problem of high-pressure and high-heat storage after the liquid storage tank is heated. How to Ensuring safety is a big issue; the other is a solution specially proposed by the applicant, which is to heat the roller brush directly, and after the heated roller brush encounters the cleaning liquid, it indirectly heats the cleaning liquid, thereby obtaining a thermal cleaning effect. Compared with the original technology, this solution further shortens the heat energy transmission path, which is beneficial to energy saving and improving response performance, and the safety problem is also better solved. In addition, by setting up an electrical connection structure, the applicant does not need to set batteries at both ends of the barrel of the roller brush or in the barrel, but is powered by the power supply of the cleaning device. On the one hand, it increases the power supply capacity and ensures endurance. On the other hand, it reduces the cost of replacing the roller brush, so that the roller brush proposed by the applicant can be actually used in life, rather than theoretically. However, even though the roller brush proposed by the applicant has the above-mentioned advantages, the applicant also hopes to further improve the energy utilization efficiency and response performance, which is of great significance for reducing battery volume, reducing costs and improving practicality.

[0004] Therefore, the applicant continued to conduct in-depth research, and through the unremitting efforts of the applicant, the applicant proposed a roller brush, which is provided with a heating part, which is in contact with and / or has a gap with the outer periphery of the rotating cylinder, and the heating part is used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part. This structure can further improve the energy utilization efficiency and response performance. In the aforementioned scheme, due to the presence of a liquid outlet, when the cleaning device stops working, it is not desired that the liquid outlet continue to discharge liquid. If the liquid outlet continues to discharge liquid, on the one hand, the cleaning liquid will be wasted, and on the other hand, the user's living environment may be wet. Therefore, the applicant proposed a heating part through research to solve the aforementioned problems, and also proposed a roller brush and a cleaning device. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a heating part, the liquid discharge of the liquid outlet can be controlled; a roller brush including the heating part; and a cleaning device including the roller brush.

[0006] Compared with the prior art, the present invention proposes a heating part, including a heat conductor, a liquid outlet part, and a flow channel on-off component that can be switched between a closed state and an open state. The side of the heat conductor facing the rotating cylinder is used to be in contact with and / or gap-fit ​​with the outer periphery of the rotating cylinder. The liquid outlet part is provided with a liquid outlet hole. The flow channel on-off component is arranged on the flow channel for supplying the cleaning liquid. When it is in the closed state, the part of the flow channel located before the flow channel on-off component is not connected with the liquid outlet hole. When it is in the open state, the part of the flow channel located before the flow channel on-off component is connected with the liquid outlet hole.

[0007] Preferably, the flow channel includes a liquid outlet flow channel, the liquid outlet hole is connected to the liquid outlet flow channel, and a flow channel on-off component is provided at or before the inlet of the liquid outlet flow channel.

[0009] Preferably, the liquid outlet channel is provided with two ends along the axis of the rotating cylinder, one of which is closed and the other end is provided with a channel opening and closing assembly. With this design, the channel opening and closing assembly is provided at one of the two ends of the liquid outlet channel, which not only ensures the continuity of the liquid outlet channel, but also facilitates the installation of the channel opening and closing assembly, i.e., no additional holes are required in the liquid outlet channel.

The sealing ring is arranged in cooperation with the outlet end, and the valve core is elastically pressed against the sealing ring by one end of the elastic member, and the other end of the elastic member is supported by the protrusion. When the pressure of the clean liquid at the outlet end is higher than the elastic force of the elastic member, the valve core opens to put the flow channel on-off assembly in an open state. With this design, the flow channel on-off assembly can be conveniently installed through the transition groove, which further facilitates production and assembly. In addition, the use of the protrusion to support the elastic member further facilitates production and assembly. In addition, the aforementioned structure is simple and compact, which is conducive to reducing the volume of the heating part. In addition, the first flow channel does not need to be provided with a complex structure for installing the flow channel on-off assembly. In addition, when the main body is manufactured by the production method of the profile, the aforementioned structure is also conducive to improving production efficiency.

[0026] Preferably, the main body is sintered and provided with a heating element.

[0027] Preferably, the main body is provided with a heating element and a heat insulating layer, and the heat insulating layer is used to conduct the heat of the heating element to the main body.

[0028] Preferably, a bracket is further included, and the main body and the bracket are distributed and connected along the front-to-back direction.

[0029] Preferably, the bracket has a concave cavity that cooperates with the main body, the upper edge of the concave cavity and the upper edge of the main body are sleeved together along the axial direction of the rotating cylinder through a first sleeve structure, and the lower edge of the concave cavity and the lower edge of the main body are sleeved together along the axial direction of the rotating cylinder through a second sleeve structure.

[0030] Preferably, the bracket is made of a heat-insulating material, and the bracket serves as a heat-insulating layer for the heating element, and the heat-insulating layer is used to conduct the heat of the heating element to the main body.

[0031] Preferably, the main body adopts an arc-shaped structure with an arc-shaped cross section.

[0032] Preferably, the side of the liquid outlet facing the rotating cylinder is used to fit in contact with and / or have a clearance with the outer periphery of the rotating cylinder, and the side of the liquid outlet facing the rotating cylinder has a recessed portion that is recessed away from the rotating cylinder, and the liquid outlet hole is located in the recess.

[0033] Preferably, the liquid outlet is located on the side surface of the recessed portion facing the counter-rotating cylinder.

[0034] Preferably, the recess is a V-shaped recess, a liquid outlet is provided on one side of the V-shaped recess, and the other side of the V-shaped recess is used to guide the liquid to fall on the cleaning portion of the rotating cylinder.

[0035] Preferably, the axial direction of the liquid outlet is offset from the radial direction of the rotating cylinder.

[0036] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0037] Because the flow channel shutoff assembly is located on the flow channel supplying the cleaning liquid, when in the closed state, the portion of the flow channel preceding the shutoff assembly is disconnected from the liquid outlet. When in the open state, the portion of the flow channel preceding the shutoff assembly is connected to the liquid outlet. Therefore, the liquid outflow from the liquid outlet can be controlled, that is, controlled by the shutoff assembly. This effectively avoids problems associated with continued liquid outflow after the device stops working.

[0038] Compared with the prior art, the present invention also proposes a roller brush, comprising a rotating cylinder and a heating part, wherein the heat conductive part and the liquid outlet part of the heating part are arranged in the circumference of the rotating cylinder, and the heat conductive part and the side of the liquid outlet part facing the rotating cylinder are in contact with and / or have a clearance fit with the outer periphery of the rotating cylinder.

[0039] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0040] The heat conductor and the side of the liquid outlet facing the rotating cylinder are in contact with and / or have a gap fit with the outer periphery of the rotating cylinder. The heat conductor is used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part. The liquid outlet is used to supply the cleaning liquid. Therefore, the heat can be transferred to the cleaning part and / or the cleaning liquid supplied to the cleaning part as quickly as possible, and be effectively used immediately after the transfer. The heating of the cleaning liquid supplied to the cleaning part refers to two situations. One is to heat the cleaning liquid in the cleaning part when the wetted cleaning part (for example, wetted with the liquid outlet) passes through the heat conductor. The other is to heat the cleaning liquid when it falls on the cleaning part, and / or heat the cleaning liquid before it falls on the cleaning part. For example, the cleaning liquid first passes through the heat conductor and is then output to the cleaning part by the liquid outlet. After such a design, the heated cleaning liquid immediately falls on the cleaning part to participate in the subsequent cleaning work. The heat utilization rate is very high and there is very little waste.

[0041] Since the heat-conducting member and the side of the liquid outlet facing the rotating cylinder are used to be in contact with and / or have a clearance fit with the outer periphery of the rotating cylinder, it is the outer periphery of the rotating cylinder that is heated, and the liquid outlet is optimized at the same time, so the heat utilization rate is very high and there is little waste. Therefore, the amount of heat required to reach a certain temperature during heating is less, and the response performance can be greatly improved. That is to say, after the heating part is turned on, in the present 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, so the response performance can be greatly improved.

[0042] Compared with the prior art, the present invention further provides a cleaning device, which includes the roller brush.

[0043] After adopting the above structure, compared with the prior art, the present invention has the following advantages: the cleaning device using the roller brush is conducive to further improving energy utilization efficiency and response performance, thereby being more conducive to extending battery life with the same battery and the same operating temperature.

DETAILED DESCRIPTION

[0067] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0068] The present invention will be further described in detail below:

[0069] The present disclosure provides a cleaning device, which includes the roller brush, for example, Figure 1 shown.

[0070] Cleaning devices such as roller brush electric mops, vacuum cleaner nozzles, 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 the present invention. It requires the overall structure to be small in size and can be suitable for small cleaning devices.

[0071] The roller brush exemplified in the present disclosure includes a rotating cylinder 3. Of course, there can be multiple rotating cylinders 3, such as two or three, but no matter how many there are, they can be obtained by making adaptive adjustments or simply copying them with reference to the solution of one. The present invention also points out that when there are multiple rotating cylinders 3, at least one rotating cylinder 3 is provided with the heating part of the present invention. When it is necessary to set a heating part for multiple rotating cylinders 3, it can be cleverly set as follows, that is, to set a heating part between two adjacent rotating cylinders 3, that is, to set a heating part for two adjacent rotating cylinders 3 to share a heating part, but at this time, both sides of the heating part can transfer heat to the corresponding rotating cylinder 3, such as setting a heating element 5 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 on both sides.

[0072] The cleaning part of the rotating cylinder 3 is generally the outermost layer, and the thickness is determined according to the cleaning performance or the requirements of the surface to be cleaned. By adopting the solution of the present invention, there is no need to modify the original structure of the rotating cylinder 3, that is, the existing rotating cylinder 3 can be used, and the cost of replacing and using the rotating cylinder 3 for the user is almost unchanged.

[0073] The water or water-related descriptions mentioned in the present disclosure do not only refer to water, but are common names. For example, a cleaning liquid tank is often called a clean water tank. The water here refers to cleaning liquid. The cleaning liquid can be pure water, a mixture of water and detergent, or a mixture of water and disinfectant.

[0074] The present disclosure provides a heating unit, comprising a heat conducting member 4, a liquid outlet, and a flow channel on-off assembly that switches between a closed state and an open state. The side of the heat conducting member 4 facing the rotating cylinder 3 is configured to abut and / or loosely fit against the outer periphery of the rotating cylinder 3. The liquid outlet is provided with a liquid outlet hole 7. The flow channel on-off assembly is disposed on a flow channel for supplying a cleaning liquid. When in the closed state, the portion of the flow channel located before the flow channel on-off assembly is disconnected from the liquid outlet hole 7. When in the open state, the portion of the flow channel located before the flow channel on-off assembly is connected to the liquid outlet hole 7. The flow channel on-off assembly controls the liquid outflow from the liquid outlet hole 7.

[0075] In some embodiments, as Figures 2 to 7 As shown, the present disclosure provides a heating portion, and no flow channel switching component is provided on the heat conducting member 4 .

[0076] In some embodiments, as Figure 8 、 9 As shown in Figures 19, 20, 21 and 22, the present disclosure provides a heating portion, and a flow channel opening and closing component is provided at the inlet of the liquid outlet flow channel 14 or before the inlet.

[0077] In some embodiments, as Figure 21 、 22 As shown, the present disclosure provides a heating part, and the heat conducting member 4 is provided with four first flow channels, wherein, along the flow direction of the cleaning liquid, the last first flow channel of the four first flow channels serves as the liquid outlet channel 14, and the outlet end of the second to last first flow channel is provided with a flow channel on-off component.

[0078] In some embodiments, as Figure 21 、 22 As shown, the outlet end of the first flow channel located on one side of the transition groove 20 is provided with a flow channel on-off assembly, which includes a sealing ring 35, a valve core and an elastic member 34. The sealing ring 35 is arranged in conjunction with the outlet end, and the valve core is elastically pressed against the sealing ring 35 by one end of the elastic member 34. The other end of the elastic member 34 is supported by the protrusion 21. When the pressure of the cleaning liquid at the outlet end is higher than the elastic force of the elastic member 34, the valve core opens to put the flow channel on-off assembly in an open state. The valve core is, for example, a sphere 33. Since the cleaning device is started, the liquid supply assembly needs to work, such as the water pump 26 working to generate pressure. Therefore, the valve core is controlled by the pressure change of the cleaning liquid to control whether it is open, so as to achieve the purpose of controlling the flow channel on-off assembly in association with the cleaning device.

[0079] In some embodiments, the flow channel on-off component is a solenoid valve structure, which switches the two states through electromagnetic force. The generation of electromagnetic force can be set to be associated with whether the cleaning device is started.

[0080] In some embodiments, the flow channel on-off component is a duckbill valve. When the pressure of the cleaning liquid at the outlet end is higher than the pressure required to open the duckbill valve, the duckbill valve opens to put the flow channel on-off component in an open state. Since the cleaning device is started, the liquid supply component needs to work, such as the water pump 26 working to generate pressure, so the duckbill valve is controlled by the pressure change of the cleaning liquid to achieve the purpose of controlling the flow channel on-off component in association with the cleaning device.

[0081] The flow channel on-off assembly may also have other structures, any of which are applicable to the present invention.

[0082] In some embodiments, as Figures 2 to 9 As shown, the present disclosure provides a heating portion, a heat conducting member 4 and a liquid outlet portion that are not integrated. Figures 2 to 7 The liquid outlet portion is not provided with a recess, as Figure 8 、 9 The liquid outlet portion is provided with a recess.

[0083] In some embodiments, as Figure 19 、 20 As shown, the present disclosure provides a heating portion, a heat conducting member 4 and a liquid outlet portion are integrally provided, and a recess 22 is provided in the liquid outlet portion.

[0084] In order to further improve the heat utilization rate and reduce waste, the liquid outlet 7 is very close to the cleaning part of the rotating cylinder 3, or even close to it. For example, the liquid outlet 7 is very close to the cleaning part of the rotating cylinder 3, so the cleaning liquid heated by the heating part can fall on the cleaning part at the shortest possible distance. In this way, the heat waste of the cleaning liquid before falling on the cleaning part can be reduced. For another example, the liquid outlet is very close to the cleaning part of the rotating cylinder 3, so after the cleaning part is heated by the heating part, the cleaning liquid output by the liquid outlet 7 falls on the cleaning part at the fastest possible speed. In this way, the heat waste caused by the time between the heated cleaning portion and the cleaning liquid is reduced, and it is hoped that the heated cleaning portion will contact the cleaning liquid as soon as possible, so that the cleaning liquid absorbs the heat from the cleaning portion. As can be seen from the above, in either case, it is hoped that the liquid outlet is very close to the cleaning portion of the rotating cylinder, or even close to it. In this way, in the case of having a recess 22, since the liquid outlet 7 is located in the recess 22, it is not easy to be blocked, so the liquid outlet 7 can be made very close to the cleaning portion of the rotating cylinder 3, or even close to it. In addition, since the side of the liquid outlet facing the rotating cylinder is used to be close to and / or have a clearance fit with the outer periphery of the rotating cylinder 3, the recess 22 and the outer periphery of the rotating cylinder 3 will form a relatively closed space, which is conducive to reducing heat loss. In addition, if the liquid outlet 7 is located on the heat conducting member 4, such a design also helps the heat conducting member 4 to be as close to the cleaning portion as possible without worrying about clogging. In addition, even if a part of the cleaning portion enters the recess, the outlet of the liquid outlet 7 is not easy to scratch the surface of the cleaning portion and cause dirt accumulation.

[0085] In some embodiments, as Figure 11 、 20 As shown, the concave portion is a V-shaped concave portion, one side of the V-shaped concave portion is provided with a liquid outlet 7, and the other side of the V-shaped concave portion is used to guide the liquid to fall on the cleaning portion of the rotating cylinder 3, for example Figure 20 As shown, the other side of the V-shaped recess is like an eaves. When the liquid outlet 7 sprays liquid, the liquid is blocked by the eaves and falls to the side of the cleaning part of the rotating cylinder 3. With this design, on the one hand, there is no need to set the axial direction of the liquid outlet to the radial direction of the rotating cylinder 3, that is, the axial direction of the liquid outlet is offset from the radial direction of the rotating cylinder 3, which is more conducive to the arrangement of the flow channel 14. In addition, the liquid outlet will not directly impact the surface of the cleaning part in the radial direction. On the other hand, the cleaning liquid splashed by the liquid outlet 7 when discharging liquid and the cleaning liquid splashed back after being sprayed onto the cleaning part are blocked by the other side, which is conducive to the liquid being more easily dispersed, so that fewer liquid outlet holes 7 are used to cover the cleaning part of the rotating cylinder 3.

[0086] like Figures 1 to 22 As shown, the present disclosure provides a roller brush, comprising a rotating cylinder 3, and also comprising a scraping assembly and a heating part arranged in sequence along the rotation direction of the rotating cylinder 3, the heating part comprising a heat conductor 4 and a heating part 5, the heating part 5 is used to heat the heat conductor 4, the side surface of the heat conductor 4 facing the rotating cylinder 3 is arranged in an arc-shaped concave surface, and the arc-shaped concave surface is used to be in contact with and / or have a gap fit with the outer periphery of the rotating cylinder 3, the scraping assembly is used to make the cleaning part discharge sewage, and the heat conductor 4 is used to heat the cleaning part after being processed by the scraping assembly and / or the cleaning liquid supplied to the cleaning part.

[0087] In some embodiments, as Figure 9 、 16 As shown in Figures 19 and 20, the heat conducting member 4 has an arc-shaped structure with an arc-shaped cross section.

[0088] In some embodiments, as Figure 2 、 3 , 10, 17, and 18, further comprising a suction port 13, through which the wastewater is sucked away. This allows for timely wastewater treatment, thereby preventing it from re-contaminating the surface being cleaned. The suction port 13 is connected to a suction pipe 32, through which the wastewater is sucked away in sequence.

[0089] In some embodiments, as Figure 2As shown, the scraping assembly is positioned away from the suction port 13. This design helps prevent the scraping assembly's adverse effects on the flow cross-section of the suction port 13, allowing the suction port 13 to fully utilize its performance. This avoidance of the suction port 13 does not require absolute avoidance, but rather involves taking certain measures to reduce the scraping assembly's obstruction of the suction port 13. This avoidance is acceptable when the adverse effects on the suction port 13 are minimal, but complete avoidance is even better.

[0090] In some embodiments, as Figure 2 As shown, along the rotation direction of the rotating cylinder 3, the suction port 13 is in front and the scraping assembly is in the back. With this design, the cleaning part has already been processed by the suction port 13 before passing through the scraping assembly, which helps to reduce the burden of the scraping assembly. Conversely, since the cleaning part has already been processed by the suction port 13, the scraping assembly can better achieve the cleaning effect on the cleaning part after the subsequent processing.

[0091] In some embodiments, as Figure 2 As shown, the suction port 13 is located at the rear side of the rotating cylinder 3, and the scraping assembly is located on the upper side of the suction port 13. After being processed by the scraping assembly, the sewage naturally flows downward, and the suction port 13 can just suck away the sewage in time, thereby helping to improve cleaning efficiency.

[0092] In some embodiments, as Figure 2 As shown, the scraping assembly adopts a scraping plate 12. Such a design has a simple and reliable structure, and the sewage is discharged in the form of scraping by the scraping plate 12. In the axial direction of the rotating cylinder 3, the cleaning part can be fully cleaned and the sewage is discharged, and the effect is better.

[0093] In some embodiments, as Figure 3 、 10 , 17, further comprising a water pump 26. The rotating cylinder 3, the heating portion, and the water pump 26 are arranged in sequence from front to back, and the water pump 26 is used to pump the cleaning liquid.

[0094] In some embodiments, as Figure 3 、 10 As shown in FIG. 17 , the motor 29 is further included. The rotating cylinder 3, the heating unit, and the motor 29 are arranged in order from front to back. A transmission assembly 30 is provided between the motor 29 and the rotating cylinder 3. The motor 29 is used to drive the rotating cylinder 3 to rotate via the transmission assembly 30. The transmission assembly 30 is located outside the other end of the heating unit. This facilitates a more compact structure.

[0095] In some embodiments, as Figure 3 、 10As shown in FIG. 17 , the water pump 26 and the motor 29 are arranged in a distributed manner on the left and right sides, and the water pump 26 is arranged toward the side where one end of the heating part is located. This is conducive to a more compact structure.

[0096] In some embodiments, as Figure 3 、 10 17, further comprising a roller brush frame 1, the roller brush frame 1 is provided with a mounting portion 31 on the rear side of the heating portion, the water pump 26 and the motor 29 are both mounted in the mounting portion 31. This facilitates better installation of the water pump 26 and the motor 29.

[0097] In some embodiments, as Figure 10 、 17 As shown, one end of the heating part is connected to a liquid inlet assembly, which is connected to a water pump 26. This facilitates a more compact structure. The liquid inlet assembly is, for example, a liquid inlet connector 16.

[0098] In some embodiments, as Figure 10 、 17 As shown, the liquid inlet assembly has a connector arranged at the rear side, which is connected to the output end of the water pump 26. This is conducive to a more compact structure. For example, the connector is connected to the output end of the water pump 26 through a connecting pipe.

[0099] In some embodiments, as Figures 1 to 18 As shown, the roller brush includes a heating part and a liquid outlet that can be separated from each other. The heating part includes a heat conductor 4 and a heating element 5. The heat conductor 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 conductor 4. The heat conductor 4 is in contact with the outer periphery of the rotating cylinder 3 and / or has a clearance fit. The heat conductor 4 is used to heat the cleaning part of the rotating cylinder 3 and / or the cleaning liquid supplied to the cleaning part. Along the rotation direction of the rotating cylinder 3, the liquid outlet is located in front of and / or behind the heat conductor 4. 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 part that can be separated from each other. When blocked, the transition water tank 6 can be taken out and the liquid outlet 7 can be cleaned. There is no need to clean the heating part. When the blockage causes it to have to be replaced, the heating part can be reused.

[0100] like Figures 8 to 18 As shown, the present disclosure provides another roller brush, which is different from the above roller brush in that the transition water tank 6 is cancelled, that is, the function of the heating part is not provided by the transition water tank 6. With this design, once a blockage occurs, only the liquid outlet needs to be cleaned, for example Figure 8 、 9As shown, the liquid outlet is connected to the lower side of the upper cover 2, and can be designed so that when the upper cover 2 is removed, the upper cover 2 is removed together with the liquid outlet, and the liquid outlet can be detachably connected to the heat conductor 4, or can be separately provided. When the liquid outlet is detachably connected to the heat conductor 4, it can be designed so that when the upper cover 2 is removed, the upper cover 2 is removed together with the liquid outlet, and the liquid outlet is separated from the heat conductor 4 by the detachable connection, so that the heat conductor 4 remains on the roller brush and is not removed, for example Figure 8 、 9 As shown in FIG11 , a bayonet 27 is provided at the front edge of the liquid outlet, and the bayonet 27 is detachably connected to the heating part. The supply of cleaning liquid to the liquid outlet can be done by the liquid supply component directly, or the liquid supply component first supplies the cleaning liquid to the heating element 5 and / or the heat conducting element 4, and then supplies the cleaning liquid to the liquid outlet after being heated by the heating element 5 and / or the heat conducting element 4, for example. Figure 9 、 13 As shown in Figures 15 and 16, the main body 17 is provided with a flow channel, the outlet of which is connected to the inlet of the liquid outlet via a detachable connecting tube 28. The liquid supply assembly delivers cleaning liquid into the flow channel through the liquid inlet 15 of the flow channel. After removing the liquid outlet, the liquid outlet hole 7 can be cleaned without cleaning the heating unit. If a blockage requires replacement, only the liquid outlet needs to be replaced, while the heating unit remains on the roller brush frame 1 and does not require any operation or replacement. In other words, the heating unit can be reused.

[0101] Of course, the liquid outlet 7 can also be integrated, for example Figure 19 As shown, the present disclosure provides another heating portion, wherein the liquid outlet 7 is integrated on the main body 17 of the heating portion.

[0102] In some embodiments, the liquid outlet portion is provided with a liquid outlet channel 14 , and each liquid outlet hole 7 is connected to the liquid outlet channel 14 .

[0103] In some embodiments, the liquid outlet channel 14 is preferably a linear channel, which can be parallel to the axis of the rotating cylinder 3 or inclined to the axis of the rotating cylinder 3. The main body or transition water tank is provided with a liquid outlet channel 14 arranged along the axis. This does not require that the liquid outlet channel 14 must be arranged parallel to the axis. Instead, it requires that each liquid outlet hole 7 can cover the clean part of the rotating cylinder 3. Therefore, the liquid outlet channel 14 needs to be able to transport liquid to each liquid outlet hole 7.

[0104] In some embodiments, in order to facilitate production and assembly, the following design is made: Figure 10 、 12As shown in Figures 13, 14, and 15, the heating part has a liquid inlet connector 16, a bracket 18, and a main body 17 extending along the axial direction of the rotating cylinder 3. The main body 17 and the bracket 18 are distributed and connected along the front-to-back direction. A flow channel extending along the axial direction of the rotating cylinder 3 is provided in the main body 17. The liquid inlet connector 16 is connected to one end of the main body 17. The liquid inlet connector 16 is connected to the flow channel. The liquid inlet connector 16 is used to connect the liquid supply component. The liquid inlet connector 16 is located on the side of one side of the bracket 18. The liquid inlet connector 16 is connected to the flow channel, which means that the liquid outlet 23 is connected to the flow channel inlet. With the bracket 18, after such a design, due to the support of the bracket 18, it is beneficial to further reduce the thickness of the main body 17, thereby further improving the energy utilization rate.

[0105] In some embodiments, the assembly order of the heating unit can be: the main body 17 is inserted along one end of the bracket 18, so that the main body 17 and the bracket 18 are connected along the axis of the rotating cylinder 3, and 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 14 As shown, the liquid inlet connector 16 is provided with two screw through holes 24, and correspondingly, one end of the main body 17 is also provided with two threaded holes 25. The screws connect and fix the liquid inlet connector 16 to one end of the main body 17 through the screw through holes 24 and the threaded holes 25. At the same time, the side of the liquid inlet connector 16 on one side of the bracket 18 closes the opening of one end of the bracket 18. A sealing gasket is provided on the side of the liquid inlet connector 16 on one side of the bracket 18. The side of the liquid inlet connector 16 on one side of the bracket 18 is tightly pressed and fixed to the end face of one end of the bracket 18 through the sealing gasket. A screw through hole 24 can also be provided at the other end of the bracket 18. Correspondingly, a threaded hole 25 is also provided at the other end of the main body 17. The screws connect and fix the other end of the main body 17 to the other end of the bracket 18 better through the screw through holes 24 and the threaded holes 25. As shown Figure 12 、 13 As shown, the bracket 18 has a concave cavity, and the upper edge and lower edge of the concave cavity are respectively engaged with the upper edge and lower edge of the main body 17 through a concave-convex socket structure. In this example, for example Figure 16 As shown, the grooves of the concave-convex socket structure are provided on the upper and lower edges of the main body 17, and the upper and lower edges of the cavity are correspondingly provided with protrusions 19 of the concave-convex socket structure. Such a structural design makes assembly very convenient and, in addition, provides more reliable support for the main body 17.

[0106] In some embodiments, the flow channel in the main body 17 is not one, but multiple, which is conducive to forming a maze flow channel, such as Figure 13 、 15As shown, there are four flow channels in the main body 17, which are arranged in parallel to each other to form a serpentine labyrinth flow channel, and the outlet of the last flow channel is connected to the liquid outlet through a connecting pipe 28. In order to simplify manufacturing, transition grooves 20 are processed at both ends of the main body 17. The transition grooves 20 are used to connect adjacent flow channels. For the closure of the transition grooves 20, for example, a sealing member can be provided at each end of the main body 17. For example, a protrusion 21 serving as a seal is provided on one side of the bracket 18 at the liquid inlet joint 16 and the other end of the bracket 18. A 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 bracket 18 can also be used as the other end of the main body 17 fixed to the other end of the bracket 18 after the main body 17 and the bracket 18 are sleeved, thereby greatly facilitating production and manufacturing.

[0107] In some embodiments, as Figure 19 、 20 As shown, the main body 17 adopts an arc structure arranged along the circumference of the rotating cylinder 3. A labyrinth flow channel is provided in the main body 17. The labyrinth flow channel starts from one end of the arc structure and extends back and forth along the axis direction of the rotating cylinder, for example, forming the serpentine labyrinth flow channel.

[0108] In some embodiments, as Figure 9 、 16 As shown in Figures 19 and 20, the main body 17 can be made of a profile, which can be a metal material or a non-metallic material, preferably a metal material, such as an aluminum alloy profile, a stainless steel profile, etc. Taking the aluminum alloy profile as an example, the aluminum alloy profile can be obtained by the existing extrusion process, that is, an elongated aluminum alloy profile is first made using an extrusion die. The die is provided with a structure, and the structure can be formed in one step along the length direction of the elongated aluminum alloy profile during the extrusion process. After the elongated aluminum alloy profile is obtained, the elongated aluminum alloy profile is cut into a certain length to obtain a single main body 17. In this way, a long aluminum alloy profile can be cut into multiple main bodies 17 by cutting. Then, the two end faces of each main body 17 are machined, and the machining is used to obtain the transition groove 20. In this way, the main body 17 used as an assembly component is completed. Next, the main body 17 used for the assembly component is assembled to obtain the above-mentioned complete heating part. The above-mentioned scheme greatly simplifies production and manufacturing, which is conducive to significantly improving production efficiency and reducing production costs. Due to the characteristics of the cleaning device field to which the present disclosure relates, namely, the structural size is preferably small and the cost cannot be too high, the aforementioned solution provides extremely important technical support for the application of the relevant solutions of the present disclosure in the cleaning device field.

[0109] In some embodiments, as Figure 14As shown, the main body 17 is further 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 protecting the heating element 5 on the one hand and simplifying production on the other hand.

[0110] In some embodiments, an installation groove is provided on the back of the main body 17, and the heating element 5 is provided in the installation groove. This is beneficial to reducing the overall thickness of the assembly formed after the main body 17 and the heating element 5 are connected, and on the other hand, a certain wrapping is formed on the heating element 5, so that more heat is conducted to the main body 17.

[0111] In some embodiments, 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 combined with the main body 17 and roughly forms an integral body. This design is conducive to smaller heat conduction losses and smaller overall thickness of the assembly formed after the main body 17 and the heating element 5 are connected.

[0112] In some embodiments, a heat insulating layer is provided on the back of the main body 17, and the heat insulating layer is used to conduct the heat of the heating element 5 to the main body 17. This is conducive to energy saving, improving the utilization rate of heat energy, and reducing waste.

[0113] In some embodiments, a separate insulation layer can be provided on the back of the main body 17, or the bracket 18 can serve as the insulation layer for the heating element 5. The bracket 18 can be made of an insulating material, which can further simplify the structure. However, if a separate insulation layer is used, the material selection of the bracket 18 is simplified, and the bracket 18 is not restricted to using insulating materials. However, the assembly step is relatively extra, namely, the need to provide a separate insulation layer.

[0114] The following examples further illustrate the roller brush of the present disclosure:

[0115] Example 1:

[0116] The present invention discloses a roller brush comprising a rotating cylinder 3, with a heating portion provided circumferentially around the outer periphery of the rotating cylinder 3. The heating portion is in contact with the outer periphery of the rotating cylinder 3 and is used to heat the cleaning portion of the rotating cylinder 3. In this way, the heat generated by the heating portion is directly in contact with and transferred to the cleaning portion, with the heat transfer distance being zero. Furthermore, once the cleaning portion is heated, it is immediately used for cleaning, resulting in high efficiency, reduced heat waste, and improved heat utilization.

[0117] The heating unit includes a heat conductor 4 and a heating element 5. The heat conductor 4 is circumferentially arranged around the outer circumference of the rotating cylinder 3, and the heating element 5 is connected to the heat conductor 4. This design facilitates heat transfer through the heat conductor 4. On the one hand, the heating element 5 involves power supply issues, and the aforementioned design facilitates the arrangement of the heating element 5. On the other hand, the heat conductor 4 can be used to simply and efficiently transfer heat more comprehensively, thereby ensuring the heated area of ​​the cleaning unit. At the same time, it helps to reduce the number of installed heating elements 5 and avoid adding excessive weight.

[0118] The brush holder 1 is provided with a first opening 9 for detachably mounting the rotating cylinder 3, and a heating unit is provided in the first opening 9. This design does not affect the replacement of the rotating cylinder 3, and after replacing the rotating cylinder 3, there is no need to adjust the distance between the heating unit and the rotating cylinder 3. That is, the brush holder can be used directly after replacement, which greatly facilitates user use.

[0119] Preferably, Figure 1 、 2 As shown in Figures 3 and 4, the roller brush frame 1 is detachably connected to the upper cover 2. The heating unit is located on the lower side of the upper cover 2. After removing the upper cover 2, the heating unit 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 limit mounting member for the rotating cylinder 3. This design can greatly facilitate the production of the present invention and is also convenient for daily use.

[0120] A heating body of the heating part is provided on the side of the heating part that is in contact with the outer periphery of the rotating cylinder 3 .

[0121] The heating element comprises a continuous heat-conducting member 4 and a discontinuous heating member 5 arranged axially. The heat-conducting member 4 is located on the outside, while the heating member 5 is located on the inside. The heat-conducting member 4 isolates the heating member 5 from the rotating cylinder 3. This simplifies the arrangement and number of installed heating members 5. Furthermore, the heat-conducting member 4 isolates the heating member 5 from the rotating cylinder 3, protecting the heating member 5 and extending its service life.

[0122] The heating part is continuously arranged along the axial direction of the rotating cylinder 3. Such a design can make the cleaning part evenly heated, which is beneficial to the cleaning performance.

[0123] The device also includes a heat-insulating structure that ensures that most of the heat generated by the heating unit is transferred to the cleaning unit. For example, the heat-insulating structure can be provided as an insulating layer behind and around the heating element 5. This allows the heat from the heating element 5 to be primarily transferred to the front side, specifically to the heat conductor 4, which then transfers the heat to the cleaning unit. This design helps reduce waste and improve heat utilization.

[0124] The side of the heating unit facing the rotating cylinder 3 includes an arc-shaped structure arranged around the rotating cylinder 3. In this example, the heat conductor 4 is configured as an arc-shaped structure, that is, the heat conductor 4 is a concave arc-shaped plate. This design aligns the concave arc-shaped plate with the outer surface of the cleaning unit, facilitating smooth rotation of the cleaning unit and ensuring a good fit between the concave arc-shaped plate and the cleaning unit, thereby improving heat transfer efficiency.

[0125] In this example, no transition water tank 6 is provided. The above structure can be referred to in the attached Figure 1 、 2 , 4, and 5, Figure 2 、 4 , 5 and omitting the transition water tank 6 to constitute the other structures of this example.

[0126] In this example, the liquid outlet and the heating part share a frame, which has a front panel with liquid outlet holes 7 provided on the front panel. Each liquid outlet hole 7 is connected to the liquid supply assembly, and the heating part assembly is detachably connected to the frame.

[0127] Example 2:

[0128] The difference between Example 2 and Example 1 is that the heating part is clearance-matched with the outer periphery of the rotating cylinder 3. The technical effect of this arrangement is that, on the one hand, the rotational resistance of the rotating cylinder 3 is reduced, and on the other hand, wear is reduced. On the other hand, the squeezing of the cleaning part is reduced, which is beneficial to avoid the loss of cleaning liquid caused by the cleaning liquid in the cleaning part being squeezed out.

[0129] Example 3:

[0130] The difference between the third embodiment and the first embodiment is that the heating part and the outer periphery of the rotating cylinder 3 are both in contact and have a clearance fit. The advantage of this arrangement is that it provides great flexibility and can flexibly set the contact and clearance fit according to the characteristics of the cleaning part, thereby further optimizing the structure.

[0131] Example 4:

[0132] Compared with embodiments 1, 2 and 3, embodiment 4 differs in that a transition water tank 6 is added, and the heating part is used to heat the cleaning liquid supplied to the cleaning part. At this time, the heating part and the outer periphery of the rotating cylinder 3 are preferably clearance-matched.

[0133] When the transition water tank 6 is added, the structure is as follows: a heating part is provided in the circumferential direction of the outer periphery of the rotating cylinder 3, and the heating part is gap-matched with the outer periphery of the rotating cylinder 3. The heating part includes the transition water tank 6, and the heating element 5 of the heating part is located in the transition water tank 6. The transition water tank 6 is used to be connected 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, so that the cleaning part is also heated by the heat brought by the cleaning liquid.

[0134] The transition water tank 6 adopts a small capacity, and the capacity of the small capacity is smaller than the capacity of the water source.

[0135] 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 volume of the cleaning liquid per unit time is set according to the cleaning needs. Generally speaking, reaching or exceeding the supply volume is conducive to better exerting the cleaning performance. However, if the capacity of the transition water tank 6 is not limited, it will bring disadvantages, so the capacity of the transition water tank 6 is also very important, just as the present invention says "the transition water tank 6 adopts a small capacity, and the capacity of the small capacity is less than the capacity of the water source." After the above design, it can better connect the amount required for cleaning use and balance energy consumption. In addition, it is also more conducive to controlling the program to control the opening and closing of the heating element 5. 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, while being able to maintain the supply volume, then the balance point at this time is more conducive to balancing the three elements of energy consumption, temperature stability control, and cleaning performance.

[0136] The transition water tank 6 is provided with a labyrinth heating channel, which is used to allow the heating element 5 to quickly heat the clean liquid flowing through it in a short time. Figure 7 As shown, the labyrinth heating flow channel of the transition water tank 6 is configured as a V-shaped labyrinth heating flow 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.

[0137] In this example, if Figure 7 As shown, the flow direction of the clean liquid in the V-shaped labyrinth heating channel is to flow in from the upper right end of the V-shaped labyrinth heating channel, and then flow out along the V-shape to the upper left end of the V-shaped labyrinth heating channel. After such a design, on the one hand, the flow distance is lengthened, so that the clean liquid has more time to absorb the heat generated by the heating element 5. On the other hand, the flow from bottom to top on the outlet side allows the heat to flow upward more easily, so the clean liquid can better carry away the heat generated by the heating element 5. In addition, because the V-shape causes the left and right channels to be closer, when the heating element 5 generates heat, the clean liquid in the top-down channel on the right side is preheated. Then, when it flows from bottom to top on the outlet side, the clean liquid can be heated to a higher temperature more quickly, shortening the heating time. In addition, the use of the V-shaped labyrinth heating channel makes the overall structure very compact. If it is necessary to further shorten the heating time, the heating element 5 can also be set simultaneously in the top-down channel on the right side.

[0138] The above design has the following technical effects: first, the cleaning liquid in the transition water tank 6 is used for the cleaning part after being heated, and there is no need for long-distance transportation, which greatly reduces waste. In addition, it also avoids the safety hazards caused by long-distance transportation. Second, according to the purpose of the invention, the amount of cleaning liquid in the transition water tank 6 is not set very much, so the heat generated by the heating element 5 is enough to heat the cleaning liquid in the transition water tank 6 in a short time, so that it can quickly enter the normal working state, and the working response is very fast. Third, when the work stops, there is not much cleaning liquid left in the transition water tank 6, so the wasted heat is very small. In addition, when When stopping work, it can be turned off in advance. For example, if the working time is set to 10 minutes, then when the 10-minute work stop time is reached, the heating element 5 is actively turned off in advance, so that the last heated cleaning liquid is also used to clean the cleaned surface, and the heated cleaning liquid will not be used up. 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 to rotate, and the hot cleaning liquid remaining in the transition water tank 6 continues to be supplied, so that the rotating cylinder 3 can clean itself, thereby utilizing the heat of this part of the cleaning liquid remaining in the transition water tank 6. Therefore, taking this measure can also further reduce waste.

[0139] Embodiment 5:

[0140] like Figure 2 、 3 , 4, 5, 6, 7, Figure 7 The middle arrow indicates the flow direction of the cleaning liquid. The difference between Example 5 and Example 4 is that not only a transition water tank 6 is added, but also a heating part is used to heat the cleaning part of the rotating cylinder 3. Specifically, in this example, the heating element 5 is circumferentially arranged 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. The heat conducting element 4 is circumferentially arranged around the outer periphery of the rotating cylinder 3. While heating the cleaning liquid, the heating element 5 also heats the cleaning part of the rotating cylinder 3 through the heat conducting element 4.

[0141] The technical effects of such a design are as follows: first, the heat generated in the front-to-back directions of the heating element 5 can be applied to the cleaning part more quickly, that is, the front side of the heating element 5 is the cleaning part, and the rear side of the heating element 5 is the cleaning liquid, so the heat generated in the front-to-back directions of the heating element 5 is more efficiently utilized. This is because the front side of the heating element 5 directly heats the cleaning part, and there is no need for the cleaning liquid in the transition water tank 6 to carry heat to heat the cleaning part, that is, one heat conversion is reduced, and the advantage of the front side of the heating element 5 directly heating the cleaning part is that it is also conducive to improving the compactness of the structure, and since the rear side of the heating element 5 cannot directly heat the cleaning part, the heat is carried by the cleaning liquid in the transition water tank 6 to superimpose the cleaning part that has been preheated by the front side of the heating element 5, so that the heat generated by the heating element 5 is more efficiently utilized. Since the heat is more efficiently utilized, it is very conducive to shortening the heating time, so that the working effect can be achieved in a short time. operating temperature; secondly, while achieving the goal of more efficient use of heat, it is conducive to further improving the compactness of the structure, thereby further reducing the thickness of the transition water tank 6; thirdly, when designing the V-shaped maze heating flow channel, the purpose of faster heating can be achieved by only setting a heating element 5 in the flow channel from bottom to top on the left side of the V-shaped maze heating flow channel, without setting heating elements 5 in the flow channels on both sides of the V-shaped maze heating flow channel, so that the overall structure is more optimized. At the same time, this also avoids the heat waste caused by setting heating elements 5 in the flow on both sides of the V-shaped maze heating flow channel. The reason is that if a heating element 5 is set in the flow channel from top to bottom on the right side of the V-shaped maze heating flow channel, the heat transfer of the heating element 5 to the right side will inevitably increase. Because it is restricted by the speed at which the clean liquid absorbs heat, it cannot be absorbed and taken away in time, resulting in heat loss. The above scheme avoids this situation.

[0142] In this example, if Figure 5 、 6 As shown, a second opening 10 is provided on the side of the transition water tank 6 facing the rotating cylinder 3. The second opening 10 allows the heating element 5 to be exposed, thereby reducing the barrier between the heating element 5 and the heat-conducting element 4 and facilitating 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 part, and also allows the transition water tank 6 to be closer to the cleaning part, so that the heated cleaning liquid can be transported to the cleaning part over a shorter distance, and the heated cleaning part and the heated cleaning liquid can meet more quickly, thereby minimizing heat loss and allowing the temperature of the cleaning part to be better maintained with a smaller heating power input, which further improves energy utilization and response performance.

[0143] In this example, if Figure 4 、 5As shown in Figure 6, in order to output the heated cleaning liquid more evenly, a plurality of liquid outlet holes 7 are sequentially provided along the axial direction of the rotating cylinder 3. The liquid outlet holes 7 are connected to the outlet end of the V-shaped labyrinth heating channel through a plurality of connecting holes 8. Therefore, the plurality of liquid outlet holes 7 are located on the upper side of the heat conductor 4. The liquid inlet end 11 of the V-shaped labyrinth heating channel is connected to the water source through a pipeline, that is, it is connected to the cleaning liquid tank. A water pump can be provided to increase the delivery pressure of the cleaning liquid. It is also possible to timely shut down the heating element 5 by detecting the water level of the cleaning liquid tank and / or whether there is cleaning liquid in the pipeline, thereby achieving higher safety performance, such as anti-dry burning performance.

[0144] For the case of simultaneous heating, other solutions are also possible. For example, while the heating element 5 is heating the cleaning liquid, the cleaning part of the rotating cylinder 3 is directly heated by the heating element 5. For another example, while the heating element 5 is heating the cleaning liquid, the transition water tank 6 also becomes hot after the cleaning liquid is heated, so the cleaning part of the rotating cylinder 3 can be heated by the heated transition water tank 6.

[0145] Example 6:

[0146] The difference between the sixth embodiment and the fifth embodiment is that the sixth embodiment further comprises a scraper 12 for scraping the cleaning part, that is, scraping off the sewage and dirt on the cleaning part together, which are then sucked away by the suction port 13 near the scraper 12. This is also a working feature of the floor scrubber. Then in Example 6, along the rotation circumference of the rotating cylinder 3, the transition water tank 6 is located on the rear side of the scraper 12, that is, the cleaning part scrapes the dirt first, and then the transition water tank 6 supplies heat. The heat includes the heat for heating the cleaning part passing through the transition water tank 6 and the heat brought by the heated cleaning liquid when it falls from the liquid outlet 7 onto the cleaning part. In this way, the heat can be utilized more effectively without wasting heat on the contaminated part of the cleaning part (the contaminated part of the cleaning part). This is because the heat will be consumed after the cleaning part cleans the cleaned surface. Then, if the sewage is not removed in time, the part of the cleaning part where the sewage is located (the contaminated part of the cleaning part) will reabsorb the heat, and the contaminated part of the cleaning part is not conducive to cleaning. Therefore, through the above design, the heat is used more effectively, thereby further reducing waste.

[0147] Embodiment seven:

[0148] Compared with the above embodiments, the difference of the embodiment 7 is that there can be multiple heating parts, each heating part is arranged along the axial direction of the rotating cylinder 3, the axial length of each heating part is roughly equal to that of the cleaning part, and each heating part is also arranged in sequence along the circumference of the rotating cylinder 3. That is to say, compared with Figure 2The structure of one heating part is shown in the figure. In embodiment 7, at least one heating part is added in sequence along the circumference of the rotating cylinder 3 to form a structure with two heating parts. Such a structure of embodiment 7 is conducive to reaching the required temperature more quickly, and if necessary, a higher temperature can be reached. However, the relatively large structure and high energy consumption have exceeded the requirements of ordinary cleaning. In some occasions where a higher temperature is required, embodiment 7 is more suitable.

[0149] Embodiment 8:

[0150] The difference between the eighth embodiment and the above embodiments is that it further includes a temperature sensor for detecting 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 to be cleaned.

[0151] By setting up temperature sensors, the following technical effects can be achieved: on the one hand, it provides a structural basis for more intelligent control of heating, and combined with the control program, it helps to further fine-tune the control of energy consumption; on the other hand, it can further improve safety and provide an additional guarantee for safety.

[0152] Embodiment 9:

[0153] like Figures 8 to 15 As shown, in this example, the transition water tank 6 is cancelled, and there is no concept of a water tank. The heating part has a main body 17 or a main body 17 with a flow channel. The 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 joint 16 is connected to one end of the main body 17, and the liquid inlet joint 16 is communicated with the flow channel. The liquid inlet joint 16 is used to connect the liquid supply component, so that the overall volume of the heating part is significantly reduced, and the liquid is fed from one end, without the need for Figure 3 As shown, the liquid is fed from the liquid inlet end 11 at the upper middle position, which is also beneficial to reducing the size in the height direction. The above-mentioned measures are beneficial to reducing the volume of the roller brush, or freeing up more space to install other structures, such as Figure 10 As shown, since 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.

[0154] In this example, the main body 17 not only heats the cleaning liquid, but also, due to its inherent heat conduction, can be used to directly heat the cleaning portion. In other words, the main body 17 also serves as the heat conductor 4, thereby accelerating the heating of the cleaning portion. This design not only provides a fast response, but also, because the heat is used to heat the cleaning liquid and directly heat the cleaning portion through the main body 17, the heat is primarily used in the cleaning portion, resulting in high energy efficiency.

[0155] Embodiment 10:

[0156] Compared with Example 9, for example Figure 11 As shown, a recess 22 extending along the axis of the rotating cylinder 3 is provided on one side of the liquid outlet portion of the rotating cylinder 3, and a liquid outlet hole 7 is provided in the recess 22. After such design, the liquid outlet hole 7 is not easy to enter dirt, and the liquid outlet is kept smooth.

[0157] In some embodiments, 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 on the side opposite to the rotation direction of the rotating cylinder 3. This design has a better anti-clogging performance. In addition, according to the above design, the cleaning part will not be tightly pressed against the liquid outlet 7, thereby facilitating smoother liquid discharge.

[0158] Example 11:

[0159] Compared with the tenth embodiment, the eleventh embodiment, for example Figure 19 、 20 As shown, the difference is that it also includes a scraper 12, which serves as the scraping component, and the liquid outlet 7 and the scraper 12 are both integrated with the heat conductor 4, in this case, integrated with 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 the cleaning part, that is, scrapes off the dirty water and dirt on the cleaning part, and then sucks them away by the suction port 13 near the scraper 12. Due to the integrated arrangement, the scraper 12 can also transfer some heat, that is, the hot scraper 12 has a better cleaning effect when processing the cleaning part than the cold scraper 12.

[0160] In some embodiments, as Figure 19 、 20 As shown, the scraper plate 12 and the heat conductor 4 are integrally provided, so that heat can be more easily transferred to the scraper plate 12 , thereby reducing heat waste. In addition, it is beneficial to simplify the structure and facilitate production.

[0161] In each embodiment, the heating element 5 adopts an electric heating structure, such as PTC heating, film heating, printed heating body, etc. Any heating element 5 suitable for the present invention can be applied to the present invention.

[0162] When understanding the present invention, if necessary, the above structure can refer to other embodiments / appendices. Figure 1 And understand, no further elaboration here.

[0163] The above description is merely an illustrative embodiment of the present invention, and therefore any equivalent changes or modifications made according to the structure, features and principles described in the patent protection scope of the present invention are included in the patent protection scope of the present invention.
