Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rolling brush electric mop, scrubber, vacuum cleaner, sweeper and the like, in particular to a heating part, a rolling brush and a cleaning device. BACKGROUND

[0002] In the cleaning device such as rolling brush electric mop, scrubber, vacuum cleaner and sweeper, the rolling brush is one of the important technical means to improve the cleaning performance. The working principle of the rolling brush is that the rolling brush is in rotational contact with the cleaned surface to clean the surface.

[0003] In order to improve the cleaning performance, a scheme of spraying cleaning liquid on the rolling brush or before and after the rolling brush is proposed. The cleaning liquid is a cleaning liquid such as cleaning agent, water and the like. In this way, the cleaning performance is improved by wetting the rolling brush or the cleaned surface. In order to further improve the cleaning performance, the cleaning liquid is heated, i.e. the hot cleaning liquid is used to improve the cleaning performance. However, at present, there are many different schemes for how to generate and supply the hot cleaning liquid. Generally, they can be divided into two kinds. One is to heat the cleaning liquid in the liquid storage tank by using electric heating or chemical energy. The liquid storage tank is connected with the rolling brush through a pipeline. The delivered cleaning liquid is sprayed on the rolling brush or the cleaned surface. There are generally two kinds of spraying on the rolling brush. One is to spray on the upper side of the outside of the rolling brush. The other is to flow from the inside of the rolling brush and then seep out from the cleaning part of the rolling brush. Such a scheme has a long delivery distance, high energy consumption and slow response. In addition, the problem of high-pressure and high-temperature storage of the heated liquid storage tank is a big problem. How to ensure safety is a big problem. The other scheme is a scheme specially proposed by the applicant, i.e. the rolling brush is directly heated. The heated rolling brush indirectly heats the cleaning liquid when it meets the cleaning liquid, thereby obtaining the hot cleaning effect. Compared with the original technology, this scheme further shortens the heat energy delivery path, is conducive to energy saving and improving the response performance, and the safety problem is also well solved. In addition, the applicant sets an electric connection structure. The battery does not need to be arranged at both ends of the cylinder or in the cylinder of the rolling brush. Instead, the power supply of the cleaning device is used for power supply. On the one hand, the power supply capacity is increased to ensure the endurance. On the other hand, the cost of replacing the rolling brush is reduced, so that the rolling brush proposed by the applicant can be practically applied to life, rather than being theoretical. However, even though the rolling brush proposed by the applicant has the above-mentioned advantages, the applicant still hopes to further improve the energy utilization efficiency and the response performance, which is of great significance to reducing the battery size, reducing the cost and improving the practicability.

[0004] Therefore, the applicant continues to conduct in-depth research, and through the unremitting efforts of the applicant, the applicant provides a rolling brush, which is provided with a heating part, the heating part is in contact and / or gap cooperation with the outer periphery of the rotating cylinder, and the heating part is used for heating the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part. The structure can further improve the energy utilization efficiency and response performance. In the foregoing scheme, the heating part is the core component, and a more optimized heating part is designed to facilitate the simplification of the structure. Therefore, the applicant provides a heating part through research to solve the foregoing problems, and further provides a rolling brush and a cleaning device. SUMMARY

[0019] As preferred, the main body adopts an arc-shaped structure arranged along the circumferential direction of the rotating cylinder, and a labyrinth flow channel is arranged in the main body, which extends back and forth along the axis direction of the rotating cylinder from one end of the arc-shaped structure.

[0020] After the above structure is adopted, compared with the prior art, the present application has the following advantages:

[0021] By arranging the heat-conducting member, the heating member and the support, the heat-conducting member is connected with the support, the support is used to support the heat-conducting member to expose one side of the heat-conducting member facing the rotating cylinder, and the heating member is used to heat the heat-conducting member, thereby forming the heating part, so that on one hand, the parts are less, which is conducive to simplifying the structure, and on the other hand, since the above design is convenient for the production and manufacture of each component.

[0022] Compared with the prior art, the present application further provides a rolling brush, which comprises a rotating cylinder and a rolling brush support, the rotating cylinder is connected with the rolling brush support, and further comprises the heating part, the support of the heating part is connected with the rolling brush support, one side of the heat-conducting member on the support facing the rotating cylinder is in contact and / or gap cooperation with the outer periphery of the rotating cylinder, and the heat-conducting member is used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part.

[0023] After the above structure is adopted, compared with the prior art, the present application has the following advantages:

[0024] Since the heating part is added compared with the prior art, how to simplify the structure of the mounting part to facilitate the production and assembly is conducive to improving the production efficiency and reducing the production cost, and the present application can connect the heat-conducting member, the heating member and the support to form a component through the support, and then install the component on the rolling brush support through the support, thereby facilitating the production and assembly, in addition, since the support is used to support the heat-conducting member to expose one side of the heat-conducting member facing the rotating cylinder, after the support is connected with the rolling brush support, the heat-conducting member does not need to be adjusted, thereby facilitating the production and assembly.

Therefore, the heat of the heat conducting part can be quickly transferred to the cleaning part and / or the cleaning liquid supplied to the cleaning part, and is immediately used effectively after being transferred. The heating of the cleaning liquid supplied to the cleaning part refers to two cases. One is that the cleaning liquid in the cleaning part is heated when the cleaning part, which has been wetted (for example, wetted by the liquid outlet part), passes through the heat conducting part. The other is that the cleaning liquid is heated when the cleaning liquid falls on the cleaning part and / or before the cleaning liquid falls on the cleaning part, for example, the cleaning liquid passes through the heat conducting part and is then output to the cleaning part by the liquid outlet part. In this way, the heated cleaning liquid immediately falls on the cleaning part to participate in the subsequent cleaning work, and the heat utilization rate is high and little waste.

[0026] Since the heat conducting part is in contact with and / or gap fit with the outer periphery of the rotating cylinder, and the heat conducting part is used to heat the cleaning part of the rotating cylinder and / or the cleaning liquid supplied to the cleaning part, the required heat for heating to a certain temperature is less. Therefore, the response performance can be greatly improved.

DETAILED DESCRIPTION

[0050] The following description is provided to enable any person skilled in the art to practice the present application. The embodiments described in the following are only examples of the present application and the skilled person can think of other obvious variations. The essential principles of the present application defined in the following description can be applied to other embodiments, variations, improvements, equivalents and other technical solutions without departing from the spirit and scope of the present application.

[0051] The present application is further described in detail as follows:

[0052] The present disclosure provides a cleaning device comprising the roller brush described above, for example as shown in Figure 1

[0053] The cleaning device such as a roller brush electric mop, a suction head of a vacuum cleaner, a sweeper, a scrubber, etc. The cleaning device referred to in the present application generally refers to a household or small cleaning device, which is also a feature of the roller brush of the present application, requiring a smaller overall structure size, which can be applied to a small cleaning device.

[0054] The roller brush exemplified by the present disclosure comprises a rotating cylinder 3. Of course, the rotating cylinder 3 can be multiple, such as two, three, etc. However, regardless of the number, the scheme can be adjusted or simply copied. The present application also points out that when there are multiple rotating cylinders 3, at least one rotating cylinder 3 is provided with a heating part. When multiple rotating cylinders 3 need to be provided with a heating part, it can be ingeniously arranged as follows, that is, a heating part is arranged between two adjacent rotating cylinders 3, that is, the two adjacent rotating cylinders 3 share a heating part. At this time, the heating part can transfer heat to the corresponding rotating cylinder 3 on both sides, such as two heating pieces 5 on both sides, or the transition water tank 6 transfers heat to the corresponding rotating cylinder 3 on both sides after being heated.

[0055] ​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 requirement of the cleaned surface. According to the application scheme, the original rotating cylinder 3 structure does not need to be modified, and the existing rotating cylinder 3 can be used. The cost of replacing and using the rotating cylinder 3 of the user is almost not increased.

[0056] The matching use of the cleaning liquid can have various cases, such as spraying on the cleaned surface by using other equipment, such as manually spraying water, and the cleaned surface wetted by the heated cleaning part can also achieve good cleaning effect. At this time, the object of heating is the cleaning part. For example, the cleaning device is provided with other liquid supply structures, such as the liquid outlet member of the disclosure, which sprays cleaning liquid on the cleaning part. The cleaning part with cleaning liquid is heated and used. If the cleaned surface is dry, but under the action of the heated wet cleaning part, good cleaning effect can also be achieved. For example, the scheme including the labyrinth flow channel and / or the transition water tank as described in the following embodiments. For example, the above-mentioned several cases can be used in any combination, that is, both manual water spraying and liquid supply structure spraying cleaning liquid can be used, or both liquid supply structure spraying cleaning liquid and transition water tank can be used, and the like. Here, they are not listed one by one.

[0057] The water or water-related description in the disclosure does not only refer to water, but also refers to the commonly used term, such as the cleaning liquid tank is also commonly called the water tank. The water here refers to the cleaning liquid. The cleaning liquid can be pure water, a mixture of water and cleaning agent, or a mixture of water and disinfectant.

[0058] As shown in Figure 4 , 5 , 6, 7, 8, 9, 12, 13, 14, 19, 20, the disclosure provides a heating part, which comprises a heat conduction member 4, a heating member 5 and a support 18. The heat conduction member 4 is connected with the support 18, and the support 18 is used to support the heat conduction member 4 to expose one side of the heat conduction member 4 facing the rotating cylinder. The heating member 5 is used to heat the heat conduction member 4. One side of the heat conduction member 4 facing the rotating cylinder 3 is used to be attached to the outer periphery of the rotating cylinder 3 and / or gap fit. The side of the heat conduction member 4 facing the rotating cylinder 3 can be an arc-shaped concave surface as described below, or other structures such as a plane, an arc-shaped convex surface, etc. Considering the technical performance, the arc-shaped concave surface is preferred.

[0059] In some embodiments, the heating member 5 can be integrally provided with the heat conduction member 4, such as sintering described below, or can be provided in a split type, such as the groove on the main body 17 described below, and the heating member 5 is installed in the groove. The heating member 5 can be arranged on one side of the heat conduction member 4, such as shown in Figure 14 . The heating member 5 can also be arranged on one side of the support 18, such as shown in Figure 5As shown, the heating member 5 is arranged in the bracket 18, and the transition water tank 6 is arranged as the bracket 18.

[0060] In some embodiments, as shown in Figures 1 to 20 As shown, the present disclosure provides a rolling brush, which comprises a rotating cylinder 3, and further comprises a scraping assembly and a heating part arranged in sequence along the rotating direction of the rotating cylinder 3, the heating part comprises a heat-conducting member 4 and a heating member 5, the heating member 5 is used for heating the heat-conducting member 4, the side of the heat-conducting member 4 facing the rotating cylinder 3 is arranged in an arc-shaped concave surface, which is used for being attached to and / or gap-fitted with the outer periphery of the rotating cylinder 3, the scraping assembly is used for discharging sewage from the cleaning part, and the heat-conducting member 4 is used for heating the cleaning part and / or cleaning liquid supplied to the cleaning part after being processed by the scraping assembly.

[0061] In some embodiments, as shown in Figure 9 , 16 , 19, 20, the heat-conducting member 4 adopts an arc-shaped structure with an arc-shaped cross section.

[0062] In some embodiments, as shown in Figure 2 , 3 , 10, 17, 18, further comprising a suction port 13, and the sewage is sucked away by the suction port 13. In this way, the sewage is treated in time, which can help to avoid the re-pollution of the cleaned surface by the sewage. The suction port 13 is connected with a suction pipe 32, and the sewage is sequentially sucked away through the suction port 13 and the suction pipe 32.

[0063] In some embodiments, as shown in Figure 2 , the scraping assembly is arranged to avoid the suction port 13. In this way, the performance of the suction port 13 can be fully played, and the adverse effect of the scraping assembly on the flow passage cross section of the suction port 13 can be avoided. The arrangement of avoiding the suction port 13 is not required to be absolutely avoided, but to take certain measures to reduce the shielding of the scraping assembly to the suction port 13, and when the avoidance reaches a certain degree, i.e. the adverse effect on the suction port 13 is very small, such avoidance is also acceptable. Of course, complete avoidance is better.

[0064] In some embodiments, as shown in Figure 2 , along the rotating direction of the rotating cylinder 3, the suction port 13 is in front of the scraping assembly. In this way, the cleaning part has been processed by the suction port 13 before passing through the scraping assembly, which can help to reduce the burden of the scraping assembly. On the contrary, since the cleaning part has been processed by the suction port 13, the scraping assembly can better achieve the cleaning effect on the cleaning part after subsequent processing.

[0065] In some embodiments, as shown in Figure 2As shown, the suction port 13 is located at the rear side of the rotating cylinder 3, and the scraping assembly is located at the upper side of the suction port 13. After being treated by the scraping assembly, the sewage naturally flows downward, and then the suction port 13 can timely suck away the sewage, thereby improving the cleaning efficiency.

[0066] In some embodiments, as shown in Figure 3 The scraping assembly adopts a scraping plate 12. This design is simple and reliable, and the sewage is discharged in the form of scraping by the scraping plate 12. In the axis direction of the rotating cylinder 3, the cleaning part can be comprehensively cleaned and the sewage can be discharged, and the effect is good.

[0067] In some embodiments, as shown in Figure 3 、 10 , 17, further comprising a water pump 26, the rotating cylinder 3, the heating part, and the water pump 26 are sequentially arranged from front to back, and the water pump 26 is used for pumping the cleaning liquid.

[0068] In some embodiments, as shown in Figure 3 、 10 , 17, further comprising a motor 29, the rotating cylinder 3, the heating part, and the motor 29 are sequentially arranged from front to back, and a transmission assembly 30 is arranged between the motor 29 and the rotating cylinder 3. The motor 29 is used for driving the rotating cylinder 3 to rotate through the transmission assembly 30, and the transmission assembly 30 is located outside the other end of the heating part. This is conducive to making the structure more compact.

[0069] In some embodiments, as shown in Figure 3 、 10 , 17, the water pump 26 and the motor 29 are arranged on the left and right sides, and the water pump 26 is arranged on the side where the one end of the heating part is located. This is conducive to making the structure more compact.

[0070] In some embodiments, as shown in Figure 10 、 10 , 17, further comprising a roller brush holder 1, the roller brush holder 1 is provided with a mounting portion 31 at the rear side of the heating part, and the water pump 26 and the motor 29 are mounted in the mounting portion 31. This is conducive to better mounting the water pump 26 and the motor 29.

[0071] In some embodiments, as shown in Figure 10 、 17 One end of the heating part is connected with a liquid inlet assembly, and the liquid inlet assembly is connected with the water pump 26. This is conducive to making the structure more compact. The liquid inlet assembly is, for example, a liquid inlet connector 16.

[0072] In some embodiments, as shown in Figures 1 to 18 、 17As shown, the liquid inlet assembly has a joint arranged at the rear side, which is in communication with the output end of the water pump 26. This facilitates a more compact structure. For example, the joint is in communication with the output end of the water pump 26 through a connecting pipe.

[0073] In some embodiments, as shown, Figure 4 As shown, the roller brush includes a separable heating part and a liquid outlet part. The heating part includes a heat conducting part 4 and a heating part 5. The heat conducting part 4 and the liquid outlet part are both arranged around the circumference of the outer periphery of the rotating cylinder 3. The heating part 5 is in heat conduction connection with the heat conducting part 4. The heat conducting part 4 is in close contact and / or gap fit with the outer periphery of the rotating cylinder 3. The heat conducting part 4 is used to heat the cleaning part of the rotating cylinder 3 and / or the cleaning liquid supplied to the cleaning part. In the direction of rotation of the rotating cylinder 3, the liquid outlet part is located at the front side and / or rear side of the heat conducting part 4. The liquid outlet part is used to output the cleaning liquid. After such design, when clogging occurs, only the liquid outlet part needs to be cleaned, for example Figures 8 to 18 As shown, the roller brush has a transition water tank 6. The transition water tank 6 has a separable heating part and a liquid outlet part. When clogging occurs, the transition water tank 6 can be removed, and then the liquid outlet hole 7 can be cleaned. The heating part does not need to be cleaned. When clogging causes replacement, the heating part can be reused.

[0074] As shown, Figure 8 The present disclosure provides another roller brush. Compared with the above roller brush, the difference lies 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. After such design, when clogging occurs, only the liquid outlet part needs to be cleaned, for example Figure 8 、 9 As shown, the liquid outlet part is connected to the lower side of the upper cover 2. When the upper cover 2 is removed, the upper cover 2 is removed together with the liquid outlet part. The liquid outlet part can be detachably connected with the heat conducting part 4, or can be separately arranged. When the liquid outlet part is detachably connected with the heat conducting part 4, when the upper cover 2 is removed, the upper cover 2 is removed together with the liquid outlet part. The liquid outlet part is separated from the heat conducting part 4 through the detachable connection. In this way, the heat conducting part 4 remains on the roller brush and is not removed, for example as shown in Figure 9 、 9 As shown, the front edge of the liquid outlet part is provided with a bayonet 27, which is detachably connected with the heating part. For the supply of cleaning liquid of the liquid outlet part, the liquid supply assembly can directly supply, or the liquid supply assembly can first supply the cleaning liquid to the heating part 5 and / or the heat conducting part 4, and then supply the heated cleaning liquid to the liquid outlet part, for example Figure 19 、 13As shown in FIGS. 15, the main body 17 is provided with a flow channel, and the outlet of the flow channel is communicated with the inlet of the liquid outlet through the detachable connecting pipe 28. The liquid supply assembly supplies the cleaning liquid into the flow channel through the liquid inlet 15 of the flow channel. After the liquid outlet is removed, the liquid outlet hole 7 can be cleaned, and the heating part does not need to be cleaned. When the liquid outlet hole is blocked and can only be replaced, only the liquid outlet needs to be replaced, and the heating part remains on the roller brush holder 1 without any operation and replacement. That is, the heating part can be reused.

[0075] Of course, the liquid outlet hole 7 can also be integrated, for example, as shown in FIG. Figure 10 The present disclosure provides another heating part, and the liquid outlet hole 7 of the heating part is integrated on the main body 17 of the heating part.

[0076] In some embodiments, the liquid outlet is provided with a liquid outlet flow channel 14, and each liquid outlet hole 7 is communicated with the liquid outlet flow channel 14.

[0077] In some embodiments, the liquid outlet flow channel 14 is preferably a straight flow channel, which can be parallel to the axis direction of the rotating cylinder 3 or inclined to the axis direction of the rotating cylinder 3. The main body or the transition water tank is provided with the liquid outlet flow channel 14 along the axis direction. It is not required that the liquid outlet flow channel 14 must be parallel to the axis direction, but it is required that each liquid outlet hole 7 can cover the cleaning part of the rotating cylinder 3, so that the liquid outlet flow channel 14 needs to be able to deliver liquid to each liquid outlet hole 7.

[0078] In some embodiments, in order to facilitate production and assembly, the following design is made, as shown in FIG. Figure 14 、 12 , 13, 14, 15, the heating part has a liquid inlet connector 16, a bracket 18, a main body 17 extending along the axis direction of the rotating cylinder 3, and the main body 17 and the bracket 18 are distributed and connected along the front and back directions. The main body 17 is provided with a flow channel extending along the axis direction of the rotating cylinder 3. The liquid inlet connector 16 is connected to one end of the main body 17, and the liquid inlet connector 16 is communicated with the flow channel. The liquid inlet connector 16 is used to connect the liquid supply assembly. The side surface of the liquid inlet connector 16 located on one side of the bracket 18 is provided with a liquid outlet 23. The liquid inlet connector 16 is communicated with the flow channel, which means that the liquid outlet 23 is communicated with the flow channel inlet. By using the bracket 18, the thickness of the main body 17 can be further reduced after this design, thereby further improving the energy utilization rate.

[0079] In some embodiments, the assembly sequence of the heating part can be that the main body 17 is inserted along one end of the bracket 18, so that the main body 17 and the bracket 18 are sleeved along the axis direction 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, as shown in FIG. Figure 12As shown, the liquid inlet connector 16 is provided with two screw through holes 24, and the one end of the main body 17 is also provided with two threaded holes 25, and the screw passes through the screw through hole 24 and the threaded hole 25 to connect and fix the liquid inlet connector 16 to the one end of the main body 17, and at the same time, the side surface of the liquid inlet connector 16 located at one side of the bracket 18 closes the opening of the one end of the bracket 18. The side surface of the liquid inlet connector 16 located at one side of the bracket 18 is provided with a sealing gasket, and the side surface of the liquid inlet connector 16 located at one side of the bracket 18 is tightly fixed together with the end surface of the one end of the bracket 18 through the sealing gasket. The other end of the bracket 18 can also be provided with a screw through hole 24, and the other end of the main body 17 is also provided with a threaded hole 25, and the screw passes through the screw through hole 24 and the threaded hole 25 to better connect and fix the other end of the main body 17 and the other end of the bracket 18 together. As shown in Figure 16 、 13 As shown, the bracket 18 has a concave cavity, and the upper edge and the lower edge of the concave cavity are respectively matched with the upper edge and the lower edge of the main body 17 through the concave-convex matching structure. In this example, as shown in Figure 13 The groove of the concave-convex matching structure is arranged on the upper edge and the lower edge of the main body 17, and the upper edge and the lower edge of the concave cavity are correspondingly provided with the convex 19 of the concave-convex matching structure. Such a structure design makes the assembly very convenient, and the support of the main body 17 is more reliable.

[0080] In some embodiments, the flow channel in the main body 17 is not one, but multiple, which is beneficial to form a labyrinth flow channel, as shown in Figure 19 、 15 The flow channel in the main body 17 is four, which are arranged in parallel to form a serpentine labyrinth flow channel, and the outlet of the last flow channel is communicated with the liquid outlet through the connecting pipe 28. In order to simplify the manufacturing, the two ends of the main body 17 are processed with transition grooves 20, which are used to communicate adjacent flow channels. For the closure of the transition groove 20, for example, a sealing member can be arranged on each end of the main body 17, for example, a protruding part 21 is arranged on each end of the main body 17 as a sealing member. The protruding part 21 and the transition groove 20 form a transition flow channel through cooperation, and the protruding part 21 of the other end of the bracket 18 can also be used as the fixation of the other end of the main body 17 to the other end of the bracket 18 after the main body 17 is matched with the bracket 18, so that the production and manufacturing are greatly facilitated.

[0081] In some embodiments, as shown in Figure 9 、 20 The main body 17 adopts an arc structure arranged along the circumference of the rotating cylinder 3, and the main body 17 is provided with a labyrinth flow channel, which reciprocally extends along the axis direction of the rotating cylinder from one end of the arc structure, for example, to form the serpentine labyrinth flow channel.

[0082] In some embodiments, as shown in Figure 14 、 16, 19, 20, the main body 17 can be made of a profile, which can be a metal material or a non-metal 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 extrusion die is used to first manufacture an aluminum alloy profile, the die is provided with a structure, which can be molded along the length direction of the aluminum alloy profile during the extrusion process, and when the aluminum alloy profile is obtained, the aluminum alloy profile is cut into a certain length to obtain a single main body 17, so that a long aluminum alloy profile can obtain multiple main bodies 17 by cutting, and then, the two end faces of each main body 17 are machined to obtain the transition groove 20, so that the main body 17 for assembly is completed, and then the main body 17 for assembly is assembled to obtain the complete heating part. The above-mentioned scheme greatly simplifies the production and manufacturing, and is beneficial to greatly improve the production efficiency and reduce the production cost. Due to the characteristics of the cleaning device field of the present disclosure, that is, the structure size is preferably small, and the cost cannot be too high, so the above-mentioned scheme provides important technical support for the application of the related scheme of the present disclosure in the cleaning device field.

[0083] In some embodiments, as shown in Figure 14 The main body 17 is also provided with a heating element 5, which is in thermal connection with the main body 17, for example, the back surface of the main body 17 is provided with the heating element 5, which is beneficial to protect the heating element 5 and simplify the production and manufacturing.

[0084] In some embodiments, the back surface of the main body 17 is provided with a mounting groove, and the heating element 5 is arranged in the mounting groove, which is beneficial to reduce the overall thickness of the assembly formed by connecting the main body 17 and the heating element 5, and to wrap the heating element 5 to make the heat more conductive to the main body 17.

[0085] In some embodiments, as shown in Figure 1 The back surface of the main body 17 is sintered with the heating element 5, for example, the electric heating material is coated on the back surface of the main body 17 and sintered, which makes the heating element 5 and the main body 17 more firmly combined and substantially integrated, which is beneficial to reduce the loss of heat conduction and to make the overall thickness of the assembly formed by connecting the main body 17 and the heating element 5 smaller.

[0086] In some embodiments, the back surface of the main body 17 is provided with a heat insulation layer for conducting the heat of the heating element 5 to the main body 17. This is beneficial to save energy, improve the utilization rate of heat energy, and reduce waste.

[0087] In some embodiments, the back of the main body 17 can be provided with a separate heat insulation layer, or the support 18 can be used as the heat insulation layer of the heating element 5. The support 18 can be made of a heat insulation material, which can further simplify the structure. However, if a separate heat insulation layer is used, the material of the support 18 is not limited to a heat insulation material, but an additional step of assembling the separate heat insulation layer is required.

[0088] The following examples further illustrate the rolling brush of the present disclosure:

[0089] Embodiment one:

[0090] The rolling brush of the present disclosure includes a rotating cylinder 3, and a heating portion is arranged around the outer periphery of the rotating cylinder 3. The heating portion is attached to 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 attached to and transferred to the cleaning portion, and the distance of heat transfer is zero. The cleaning portion is immediately used for cleaning after being heated, which is high in use efficiency, reduces waste of heat, and improves the effective utilization rate of heat.

[0091] The heating portion includes a heat conduction element 4 and a heating element 5. The heat conduction element 4 is arranged around the outer periphery of the rotating cylinder 3, and the heating element 5 is connected to the heat conduction element 4. In this way, heat can be conveniently transferred through the heat conduction element 4. On the one hand, the heating element 5 involves power supply issues, and the structure of the heating element 5 can be conveniently arranged according to the foregoing design. On the other hand, through the heat conduction element 4, heat can be simply and efficiently transferred more comprehensively, which is conducive to ensuring the heating area of the cleaning portion, and is also conducive to reducing the installation number of the heating element 5 and avoiding excessive weight.

[0092] The rolling brush further includes a rolling brush holder 1, which is provided with a first opening 9 for detachably mounting the rotating cylinder 3. The heating portion is arranged in the first opening 9. In this way, the replacement of the rotating cylinder 3 is not affected, and after the replacement of the rotating cylinder 3, the distance between the heating portion and the rotating cylinder 3 no longer needs to be adjusted. That is, after replacement, the rolling brush can be directly used, which greatly facilitates the use of users.

[0093] Preferably, as shown in Figure 1 、 2 , the rolling brush holder 1 is detachably connected with an upper cover 2, and the heating portion is located at the lower side of the upper cover 2. After the upper cover 2 is removed, the heating portion can be seen, and in addition, after the upper cover 2 is removed, the rotating cylinder 3 can be removed in the up-down direction for cleaning or replacement. That is, the upper cover 2 simultaneously serves as a limiting mounting element of the rotating cylinder 3. In this way, the production and manufacture of the present disclosure can be greatly facilitated, and the daily use of users can be facilitated.

[0094] The side of the heating portion for attaching to the outer periphery of the rotating cylinder 3 is provided with a heating body of the heating portion.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] In this example, the transition water tank 6 is not included. The above structure can be referenced in the appendix. Figure 2 , 2 As shown in Figures 4 and 5, Figure 7 , 4 This example can be constructed by omitting the other structures of the transition water tank 6 in section 5.

[0100] 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.

[0101] Example 2:

[0102] 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.

[0103] Example 3:

[0104] 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.

[0105] Example 4:

[0106] 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.

[0107] 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.

[0108] The transition water tank 6 has a small capacity, which is smaller than the capacity of the water source.

[0109] 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.

[0110] 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.

[0111] In this example, as Figure 2As shown, the flow direction of the cleaning liquid in the V-shaped labyrinth heating flow channel is from the upper right end of the V-shaped labyrinth heating flow channel, and then flows along the V-shaped to the upper left end of the V-shaped labyrinth heating flow channel. After this design, on the one hand, the flow distance is lengthened, so that the cleaning liquid has more time to absorb the heat generated by the heating element 5. On the other hand, the flow from the bottom to the top at the outlet side makes the cleaning liquid better carry away the heat generated by the heating element 5, because the heat is more likely to flow upwards. In addition, due to the V-shaped structure, the left and right flow channels are relatively close, so that the cleaning liquid in the right upward flow channel is preheated when the heating element 5 generates heat, and then flows from the bottom to the top at the outlet side, which can heat the cleaning liquid to a higher temperature more quickly, thereby shortening the heating time. In addition, the use of the V-shaped labyrinth heating flow channel makes the overall structure very compact. If it is necessary to further shorten the heating time, the heating element 5 can also be arranged in the right upward flow channel.

[0112] After the above design, the following technical effects are achieved: First, the cleaning liquid in the transition water tank 6 is used for cleaning after being heated, without the need for long-distance transportation, greatly reducing waste, and avoiding safety hazards caused by long-distance transportation. Second, as can be known from the purpose of the application, the amount of cleaning liquid in the transition water tank 6 will not be set too much, 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, thereby quickly entering the normal working state, with very fast working response. Third, when the work is stopped, the cleaning liquid remaining in the transition water tank 6 is not much, so the wasted heat is very little. In addition, when the work is stopped, the heating element 5 can be closed in advance, for example, if the working time is set to 10 minutes, the heating element 5 is actively closed in advance when the 10-minute working stop time is reached, so that the last heated cleaning liquid is also used for cleaning the surface being cleaned, rather than the heated cleaning liquid not being used up. Of course, other measures can also be taken, such as closing the heating element 5 in advance, but the rotating cylinder 3 continues 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 be cleaned in this way, thereby utilizing the heat of the cleaning liquid remaining in the transition water tank 6. Therefore, this measure can also further reduce waste.

[0113] Example Five:

[0114] As shown in Figure 7 , 3 , 4, 5, 6, 7, Figure 5The middle arrow indicates the flow direction of the cleaning liquid. Compared with example four, example five is different in that not only the transition water tank 6 is increased, but also the heating part is used to heat the cleaning part of the rotating cylinder 3. In this example, specifically, the heating part 5 is arranged in the circumferential direction around the outer periphery of the rotating cylinder 3. The heating part 5 not only heats the cleaning liquid, but also includes the heat conduction part 4 arranged in the circumferential direction around the outer periphery of the rotating cylinder 3. The heating part 5 not only heats the cleaning liquid, but also heats the cleaning part of the rotating cylinder 3 through the heat conduction part 4.

[0115] The design has the following technical effects. First, the heat generated by the heating part 5 in the front-rear direction can be more quickly applied to the cleaning part. That is, the front side of the heating part 5 is the cleaning part, and the rear side of the heating part 5 is the cleaning liquid. The heat generated by the heating part 5 in the front-rear direction is more efficiently utilized. This is because the front side of the heating part 5 directly heats the cleaning part, without the 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. The front side of the heating part 5 directly heats the cleaning part, which is also beneficial to improve the compactness of the structure. The rear side of the heating part 5 cannot directly heat the cleaning part, so the cleaning liquid in the transition water tank 6 carries heat to superimpose the cleaning part that has been preheated by the front side of the heating part 5. Thus, the heat generated by the heating part 5 is more efficiently utilized. The heat is more efficiently utilized, which is very beneficial to shorten the heating time and enable the working temperature to be reached in a short period of time. Second, while achieving the purpose of more efficient utilization of heat, the compactness of the structure is further improved, thereby further reducing the thickness of the transition water tank 6. Third, when designing the V-shaped labyrinth heating flow channel, the heating part 5 arranged in the lower-to-upper flow channel on the left side of the V-shaped labyrinth heating flow channel can achieve the purpose of faster heating, without the need for the heating part 5 arranged in the upper-to-lower flow channel on the right side of the V-shaped labyrinth heating flow channel. This makes the overall structure more optimized. In addition, this avoids the heat waste caused by the heating part 5 arranged in the upper-to-lower flow channel on the right side of the V-shaped labyrinth heating flow channel. The reason is that if the heating part 5 is arranged in the upper-to-lower flow channel on the right side of the V-shaped labyrinth heating flow channel, the heat transfer of the heating part 5 to the right side will be increased. However, due to the speed of the cleaning liquid absorbing heat, the heat cannot be timely absorbed and removed, thereby causing heat loss. The above solution avoids this situation.

[0116] In this example, as shown in FIG. 5, the heating part 5 is arranged in the circumferential direction around the outer periphery of the rotating cylinder 3. The heating part 5 not only heats the cleaning liquid, but also includes the heat conduction part 4 arranged in the circumferential direction around the outer periphery of the rotating cylinder 3. The heating part 5 not only heats the cleaning liquid, but also heats the cleaning part of the rotating cylinder 3 through the heat conduction part 4. Figure 4 、 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.

[0117] In this example, as Figure 2 , 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.

[0118] 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.

[0119] Example 6:

[0120] The difference between the embodiment six and the embodiment five is that the embodiment six further comprises a squeegee 12 which squeegethe cleaning part, that is, squeegethe dirt and the sewage on the cleaning part, and then the sewage is sucked by the suction port 13 near the squeegee 12, which is also the working feature of the scrubber. In the embodiment six, along the circumferential direction of the rotating cylinder 3, the transition water tank 6 is located at the rear side of the squeegee 12, that is, the cleaning part is squeeget first, and then the heat is supplied by the transition water tank 6, the heat includes the heat of the cleaning part passing through the transition water tank 6 and the heat taken away by the cleaning liquid falling on the cleaning part from the liquid outlet hole 7, so that the heat can be more effectively utilized without wasting the heat on the contaminated part of the cleaning part (the contaminated part of the cleaning part), because the heat is consumed after the cleaning part cleans the surface to be cleaned, and 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, so the above design makes the heat more effectively used, thereby further reducing the waste.

[0121] Embodiment seven:

[0122] The difference between the embodiment seven and the above-mentioned embodiments is that the heating part can be multiple, each heating part is arranged along the axial direction of the rotating cylinder 3, the axial length of each heating part is substantially equal to the length of the cleaning part, and each heating part is sequentially arranged along the circumferential direction of the rotating cylinder 3, that is, compared with the structure of one heating part shown in the above-mentioned embodiments, the embodiment seven sequentially increases at least one heating part along the circumferential direction of the rotating cylinder 3, and forms a structure of two heating parts. Figures 8 to 15 The structure of the embodiment seven is beneficial to more quickly reach the required temperature, and if necessary, a higher temperature can also be reached, but the relative structure is larger and the energy consumption is higher, which has exceeded the requirement of ordinary cleaning, and the embodiment seven is more suitable for some occasions which require a higher temperature.

[0123] Embodiment eight:

[0124] The difference between the embodiment eight and the above-mentioned embodiments is that the embodiment eight further comprises a temperature sensor, the temperature sensor 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 to be cleaned.

[0125] By arranging the temperature sensor, the technical effect that can be achieved is that on the one hand, it provides a structural basis for more intelligent control of heating, and helps to further finely control the energy consumption in combination with the control program, and on the other hand, it can further improve the safety and provide an additional guarantee for safety.

[0126] Embodiment nine:

[0127] As shown in the above-mentioned embodiments, the cleaning part is arranged along the circumferential direction of the rotating cylinder 3, and the heating part is arranged along the axial direction of the rotating cylinder 3, so that the heat of the heating part can be effectively transferred to the cleaning part, and the heat of the cleaning part can be effectively transferred to the surface to be cleaned. Figure 3As 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 10 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 11 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.

[0128] 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.

[0129] Example 10:

[0130] 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.

[0131] In some embodiments, such as Figure 19 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.

[0132] Example 11:

[0133] Compared to Example 10, Example 11 is, for example... Figure 19 , 20As shown, the difference lies in that the squeegee plate 12 is further included as the squeegee assembly, and the liquid outlet hole 7 and the squeegee plate 12 are both integrally arranged on the heat-conducting member 4, in this case, on the main body 17. Specifically, the liquid outlet hole 7 is located near the upper edge of the main body 17, and the squeegee plate 12 is located near the lower edge of the main body 17. The squeegee plate 12 squeegees the cleaning part, i.e., squeegees the sewage and dirt on the cleaning part, and then the sewage and dirt are sucked away by the suction port 13 near the squeegee plate 12. Due to the integrated arrangement, the squeegee plate 12 can also transfer part of the heat, i.e., the hot squeegee plate 12, which has a better cleaning effect on the cleaning part than the cold squeegee plate 12.

[0134] In some embodiments, as shown in Figure 1 、 20 The squeegee plate 12 is integrally arranged with the heat-conducting member 4, so that it is easier to conduct heat to the squeegee plate 12 and reduce heat waste, and in addition, it is beneficial to simplify the structure and facilitate production and manufacturing.

[0135] For each embodiment, the heating member 5 adopts an electric heating structure, such as PTC heating, film heating, printed heating body, etc. Any heating member 5 suitable for the present application can be applied to the present application.

[0136] In understanding the present application, if necessary, the above structure can refer to other embodiments / attached ​ It is understood that the above is not repeated here.

[0137] The above description is only an embodiment of the present application for illustration, so any equivalent changes or modifications made to the structure, features and principles described in the scope of the present application are included in the scope of the present application.
