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 rolling brush and cleaning device. BACKGROUND

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

[0003] In order to improve the cleaning performance, there is a proposal to spray cleaning liquid such as cleaning agent, water and the like cleaning liquid before and after the rolling brush, so as to improve the cleaning performance by wetting the rolling brush or the cleaned surface. In addition, in order to further improve the cleaning performance, there is a proposal to heat the cleaning liquid, that is, to use hot cleaning liquid to improve the cleaning performance. However, at present, there are many different schemes for how to generate and supply hot cleaning liquid, which can be roughly divided into two kinds: one is to heat the cleaning liquid in the liquid tank by using electric heating or chemical energy, and the liquid 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 spraying on the upper side of the rolling brush outside, and the other is flowing from the inside of the rolling brush and then seeping out from the cleaning part of the rolling brush. Such scheme has long delivery distance, high energy consumption and slow response. In addition, there is a problem of high-pressure and high-temperature storage of the heated liquid tank, and how to ensure safety is a big problem. The other is a scheme specially proposed by the applicant, that is, to heat the rolling brush directly. After the heated rolling brush meets the cleaning liquid, the cleaning liquid is indirectly heated, so as to obtain 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, and does not need to set a battery in the both ends of the cylinder or in the cylinder of the rolling brush, but is powered by the power supply of the cleaning device. On the one hand, it increases the power supply capacity and ensures the endurance, and on the other hand, it reduces the cost of replacing the rolling brush, so that the rolling brush proposed by the applicant can be actually 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 response performance, which is of great significance to reduce the battery size, reduce the cost and improve 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 that is attached to the outer periphery of the rotating cylinder and / or gap fit, 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. The structure can further improve the energy utilization efficiency and response performance. In the foregoing scheme, since the energy utilization efficiency has been greatly improved, it is more difficult to further reduce energy waste on the basis of the foregoing. Therefore, the applicant provides a rolling brush through research, which is beneficial to further reduce energy waste. SUMMARY

DETAILED DESCRIPTION

[0051] The following description is provided to enable any person skilled in the art to practice the present application. The embodiments described in the following description are only examples of the present application and are not intended to limit the scope of the present application. The principles described 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.

[0052] The present application is further described in detail below:

[0053] The present disclosure provides a cleaning device comprising the roller brush as described above, for example as shown in Figure 1 .

[0054] 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-sized cleaning device, which is also a feature of the roller brush of the present application, requiring a relatively small overall structure size, which can be applied to a small-sized cleaning device.

[0055] The example roller brush of the present disclosure includes a rotating cylinder 3, of course, the rotating cylinder 3 can be multiple, such as two, three, etc., but no matter how many, can be adapted to the scheme of one or simply copied, 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 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, but at this time the heating part can transmit 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 is heated, and the transition water tank 6 transmits heat to the corresponding rotating cylinder 3 on both sides.

[0056] 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 demand of the cleaned surface. With the present invention, 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.

[0057] The use of cleaning liquid can have many situations, such as using other equipment to sprinkle on the cleaned surface, such as manually sprinkling water, the heated cleaning part will also achieve good cleaning effect when encountering wet cleaned surface, at this time the object of heating is the cleaning part, and for example, the cleaning device is provided with other liquid supply structure, for example, the liquid outlet piece of the present disclosure, the liquid supply structure sprays cleaning liquid on the cleaning part, and the cleaning part with cleaning liquid is heated for use, if the cleaned surface is dry, but under the action of the heated wet cleaning part, it will also achieve good cleaning effect, and for example, the scheme including the labyrinth flow channel and / or the transition water tank as described in the following embodiment, and for example, the above several situations can be arbitrarily combined for use, that is, both manual watering 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, etc. Here is not listed one by one.

[0058] The water or water-related description of the present 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, and 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.

[0059] As Figures 1 to 20As shown, the present disclosure provides a rolling brush, which comprises a rotating cylinder 3, a heat conducting member 4 and a heat insulation part. The rotating cylinder 3, the heat conducting member 4 and the heat insulation part are sequentially arranged. The heat conducting member 4 is in contact with the outer periphery of the rotating cylinder 3 or is in clearance fit with the outer periphery of the rotating cylinder 3. The heat conducting member 4 is used for heating the cleaning part and / or the cleaning liquid supplied to the cleaning part. The heat insulation part is used for conducting the heat of the heat conducting member 4 to the side of the rotating cylinder.

[0060] In some embodiments, as shown in Figure 16 , 19 , 20, the heat insulation part is provided with a recessed cavity. The heat conducting member 4 is installed in the recessed cavity, for example, the main body 17 is installed in the recessed cavity. The recessed cavity itself is made of heat insulation material. The recessed cavity is used for conducting the heat of the heat conducting member to the side of the rotating cylinder. Alternatively, the recessed cavity is provided with a heat insulation layer as a separate part. The heat insulation layer is used for conducting the heat of the heat conducting member to the side of the rotating cylinder.

[0061] In some embodiments, the heat insulation part comprises a heat insulation layer located at the back side of the main body 17, for example, the part of the recessed cavity of the bracket 18 serves as the heat insulation layer. Alternatively, the heat insulation part comprises a heat insulation layer located at the back side of the main body 17 and arranged around the periphery of the main body 17, for example, the part of the recessed cavity of the bracket 18 and the two ends of the bracket 18 both serve as the heat insulation layer. In this way, the situation of heat conduction waste from the two ends of the main body 17 can be reduced.

[0062] In some embodiments, as shown in Figure 3 , 16 , 19, 20, a scraping assembly is further included. The scraping assembly is used for discharging the sewage from the cleaning part. The heat conducting member 4 is used for heating the cleaning part after being processed by the scraping assembly and / or the cleaning liquid supplied to the cleaning part.

[0063] In some embodiments, as shown in Figure 2 , 3 , 10, 17, 18, a suction port 13 is further included. The sewage is sucked away by the suction port 13. In this way, the sewage is timely treated, which can be beneficial to avoid the sewage from re-polluting the cleaned surface. The suction port 13 is connected with a suction pipe 32. The sewage sequentially passes through the suction port 13 and the suction pipe 32 to be sucked away.

[0064] In some embodiments, as shown in Figure 2 , the scraping assembly avoids the suction port 13. In this way, the design is beneficial to avoid the adverse effect of the scraping assembly on the flow passage cross section of the suction port 13, so that the performance of the suction port 13 can be brought into play. The avoidance of the suction port 13 is not required to be absolute avoidance. Instead, it refers to taking certain measures to reduce the shielding of the suction port 13 by the scraping assembly. When the avoidance reaches a certain degree, that is, the adverse effect on the suction port 13 is very small, then this avoidance is also acceptable. Of course, complete avoidance is better.

[0065] In some embodiments, as shown in Figure 2As shown, along the rotation direction of the rotating cylinder 3, the suction port 13 is in front and the scraping assembly is in back. After this design, the cleaning part has been processed by the suction port 13 before the scraping assembly, which is beneficial 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 of the cleaning part after subsequent processing.

[0066] In some embodiments, as shown in Figure 2 , the suction port 13 is located on the back side of the rotating cylinder 3, and the scraping assembly is located on the upper side of the suction port 13. After this design, the sewage naturally flows downward after being processed by the scraping assembly, and then the suction port 13 can timely suck away the sewage, thereby improving the cleaning efficiency.

[0067] In some embodiments, as shown in Figure 2 , the scraping assembly adopts a scraping plate 12. After this design, the structure is relatively simple and reliable, and the sewage is discharged in the form of scraping by the scraping plate 12, which can comprehensively clean and discharge the sewage in the axial direction of the rotating cylinder 3, and the effect is good.

[0068] 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 to pump the cleaning liquid.

[0069] 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, a transmission assembly 30 is arranged between the motor 29 and the rotating cylinder 3, the motor 29 is used to drive the rotating cylinder 3 to rotate through the transmission assembly 30, and the transmission assembly 30 is located on the other end of the heating part. This is beneficial to make the structure more compact.

[0070] 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 of the one end of the heating part. This is beneficial to make the structure more compact.

[0071] In some embodiments, as shown in Figure 3 , 10 , 17, further comprising a rolling brush holder 1, the rolling brush holder 1 is provided with a mounting part 31 on the back side of the heating part, and the water pump 26 and the motor 29 are mounted in the mounting part 31. This is beneficial to better install the water pump 26 and the motor 29.

[0072] In some embodiments, as shown in Figure 10 , 17As shown in the figure, 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. In this way, the structure is more compact. The liquid inlet assembly is, for example, a liquid inlet joint 16.

[0073] In some embodiments, as shown in the figure, Figure 10 , 17 As shown in the figure, the liquid inlet assembly has a joint arranged on the rear side, and the joint is in communication with the output end of the water pump 26. In this way, the structure is more compact. For example, the joint is in communication with the output end of the water pump 26 through a connecting pipe.

[0074] In some embodiments, as shown in the figure, Figures 1 to 18 As shown in the figure, the roller brush includes a heating part and a liquid outlet part that can be separated from each other. 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-conducting connection with the heat-conducting part 4. The heat-conducting part 4 is in abutment with the outer periphery of the rotating cylinder 3 and / or in clearance 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 on the front side and / or the rear side of the heat-conducting part 4. The liquid outlet part is used to output the cleaning liquid. In this design, once a blockage occurs, only the liquid outlet part needs to be cleaned, for example, Figure 4 As shown in the figure, the roller brush has a transition water tank 6. The transition water tank 6 has a heating part and a liquid outlet part that can be separated from each other. When a blockage 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 a blockage occurs and only the heating part can be replaced, the heating part can be reused.

[0075] As shown in the figure, Figures 8 to 18 The present disclosure provides another roller brush. Compared with the above-mentioned 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. In this design, once a blockage occurs, only the liquid outlet part needs to be cleaned, for example, Figure 8 , 9 As shown in the figure, the liquid outlet part is connected to the lower side of the upper cover 2. The upper cover 2 can be designed to be taken out 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, the upper cover 2 can be designed to be taken out 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, Figure 8 , 9 As shown in the figure, a bayonet 27 is arranged on the front edge of the liquid outlet part. The bayonet 27 is detachably connected with the heating part. For the supply of the cleaning liquid of the liquid outlet part, the liquid supply assembly can directly supply the cleaning liquid, 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 cleaning liquid to the liquid outlet part for output after the cleaning liquid is heated by the heating part 5 and / or the heat-conducting part 4, for exampleFigure 9 、 13 , 15, the main body 17 is provided with a flow channel, the flow channel outlet is communicated with the liquid outlet through the detachable connecting pipe 28, and 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 blockage causes replacement, only the liquid outlet needs to be replaced, and the heating part remains on the roller brush holder 1 and does not need any operation and replacement, that is, the heating part can be reused.

[0076] Of course, the liquid outlet hole 7 can also be integrally arranged, for example, as shown in Figure 19 , the disclosure provides another heating part, and the liquid outlet hole 7 of the heating part is integrally arranged on the main body 17 of the heating part.

[0077] 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.

[0078] In some embodiments, the liquid outlet flow channel 14 is preferably a linear 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 arranged along the axis direction, which is not required to be parallel to the axis direction, but 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.

[0079] In some embodiments, in order to facilitate production and assembly, the following design is made, as shown in Figure 10 、 12 , 13, 14, 15, the heating part has a liquid inlet connector 16, a support 18, a main body 17 extending along the axis direction of the rotating cylinder 3, the main body 17 and the support 18 are distributed and connected along the front-rear direction, 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, the liquid inlet connector 16 is communicated with the flow channel, and 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 support 18 is provided with a liquid outlet 23, and the liquid inlet connector 16 is communicated with the flow channel, that is, the liquid outlet 23 is communicated with the flow channel inlet. By using the support 18, the thickness of the main body 17 can be further reduced after the design, so as to further improve the energy utilization rate.

[0080] In some embodiments, the assembly sequence of the heating part can be that the main body 17 is inserted along one end of the support 18, so that the main body 17 and the support 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 support 18 and / or the liquid inlet connector 16 is connected to one end of the main body 17, for example, as shown in Figure 14As 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 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. As shown in Figure 12 、 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 16 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 in addition, the support of the main body 17 is more reliable.

[0081] In some embodiments, as shown in Figure 16 、 19 , the upper edge and the lower edge of the bracket 18 have a certain covering to the upper edge and the lower edge of the main body 17, for example, the above-mentioned concave-convex matching structure is adopted. On the one hand, the support of the main body 17 is more reliable, and the structure is simple and compact, and on the other hand, the heat preservation effect can be enhanced, so that the heat of the main body 17 is as little as possible to be conducted and wasted from the upper edge and the lower edge of the main body 17.

[0082] In some embodiments, the flow channel in the main body 17 is not one, but multiple. This is conducive to forming a labyrinth flow channel, as shown in Figure 13 、 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 element 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 element. The protruding part 21 and the transition groove 20 form a transition flow channel through cooperation. The protruding part 21 of the other end of the bracket 18 can also be used as the other end of the main body 17 after the main body 17 and the bracket 18 are matched to fix the other end of the main body 17 to the other end of the bracket 18, so that the production and manufacturing are greatly facilitated.

[0083] In some embodiments, as shown in Figure 9 , 12 , 13, 14, the main body 17 adopts an arc-shaped structure arranged along the circumference of the rotating cylinder 3, and the main body 17 is provided with a labyrinth flow channel which extends back and forth along the axis direction of the rotating cylinder from one end of the arc-shaped structure, for example, forming the above-mentioned serpentine labyrinth flow channel.

[0084] In some embodiments, as shown in Figure 14 , the main body 17 is also provided with a heating element 5 which is in heat-conducting 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 on the one hand to protect the heating element 5 and on the other hand to simplify production and manufacturing.

[0085] 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 on the one hand to reduce the overall thickness of the assembly formed after the main body 17 is connected with the heating element 5 and on the other hand to form a certain wrapping for the heating element 5 so that more heat is conducted to the main body 17.

[0086] In some embodiments, as shown in Figure 14 , the heating element 5 is sintered on the back surface of the main body 17, for example, the electric heating material is applied on the back surface of the main body 17 and sintered, which makes the heating element 5 more firmly combined with the main body 17 and substantially forms an integral whole, which is beneficial to reduce the loss of heat conduction and to make the overall thickness of the assembly formed after the main body 17 is connected with the heating element 5 smaller.

[0087] In some embodiments, the back surface of the main body 17 is provided with a heat insulation layer which is used to conduct 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.

[0088] In some embodiments, the back surface of the main body 17 can be separately provided with a heat insulation layer, or the bracket 18 can be used as the heat insulation layer of the heating element 5, and the bracket 18 can be made of heat insulation material, which can further simplify the structure. However, if a separate heat insulation layer is used, the material selection of the bracket 18 will not be limited to heat insulation material, but one more step of assembly is needed, i.e. a separate heat insulation layer needs to be arranged.

[0089] The following examples of multiple embodiments are further described to further illustrate the rolling brush of the present disclosure:

[0090] Embodiment one:

[0091] The rotating cylinder 3 is provided with a heating part in the circumferential direction of the outer periphery of the rotating cylinder 3, and the heating part is attached to the outer periphery of the rotating cylinder 3, and the heating part is used to heat the cleaning part of the rotating cylinder 3. In this way, the heat generated by the heating part is directly attached to the cleaning part and is transmitted to the cleaning part, the distance of heat transmission is zero, and the cleaning part is heated immediately for cleaning, the use efficiency is high, the waste of heat is reduced, and the effective utilization rate of heat is improved.

[0092] The heating part comprises a heat-conducting member 4 and a heating member 5, the heat-conducting member 4 is arranged in the circumferential direction of the outer periphery of the rotating cylinder 3, and the heating member 5 is connected with the heat-conducting member 4. In this way, the heat can be conveniently transmitted through the heat-conducting member 4, on the one hand, the heating member 5 involves power supply problems, and the structure of the heating member 5 can be conveniently arranged according to the foregoing design, on the other hand, through the heat-conducting member 4, the heat can be simply and efficiently transmitted more comprehensively, thereby being beneficial to guarantee the heating area of the cleaning part, and being beneficial to reduce the installation number of the heating member 5 and avoid increasing excessive weight.

[0093] Further comprising a rolling brush frame 1, the rolling brush frame 1 is provided with a first opening 9 for detachably mounting the rotating cylinder 3, and the heating part 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 part and the rotating cylinder 3 does not need to be adjusted, that is, the rolling brush frame 1 can be directly used after the replacement, which greatly facilitates the use of users.

[0094] Preferably, as shown in Figure 1 、 2 , the rolling brush frame 1 is detachably connected with an upper cover 2, the heating part is located at the lower side of the upper cover 2, after the upper cover 2 is taken off, the heating part can be seen, in addition, after the upper cover 2 is taken off, the rotating cylinder 3 can be removed along the up-down direction for cleaning or replacement, that is, the upper cover 2 simultaneously serves as a limiting mounting piece of the rotating cylinder 3. In this way, the production and manufacture of the rolling brush frame 1 can be greatly facilitated, and the daily use of users is also facilitated.

[0095] The side of the heating part for being attached to the outer periphery of the rotating cylinder 3 is provided with a heating body of the heating part.

[0096] The heating body comprises a continuous heat-conducting member 4 arranged in the axial direction and a non-continuous heating member 5, the heat-conducting member 4 is on the outer side, the heating member 5 is on the inner side, and the heat-conducting member 4 separates the heating member 5 from the rotating cylinder 3. In this way, on the one hand, the setting and installation number of the heating member 5 are simplified, on the other hand, the heat-conducting member 4 separates the heating member 5 from the rotating cylinder 3, which is beneficial to protect the heating member 5 and prolong the service life.

[0097] The heating part is continuously arranged along the axial direction of the rotating cylinder 3. In this way, the cleaning part can be uniformly heated, which is beneficial to the cleaning performance.

[0098] The heat insulation structure is, for example, a heat insulation layer arranged at the rear and around the heating element 5, so that the heat of the heating element 5 is mainly transferred to the front side, i.e. mainly to the heat conducting element 4, which in turn transfers the heat to the cleaning part. This design is conducive to reducing waste and improving heat utilization.

[0099] The heating part towards the side of the rotating cylinder 3 comprises an arc structure arranged around the rotating direction of the rotating cylinder 3. In this example, the heat conducting element 4 is arranged in an arc structure, i.e. the heat conducting element 4 is a concave arc plate. After this design, the concave arc plate matches the outer peripheral surface of the cleaning part, which is conducive to the smooth rotation of the cleaning part and the good fit between the concave arc plate and the cleaning part, thereby improving the heat transfer efficiency.

[0100] In this example, no transition water tank 6 is arranged, and other structures in which the transition water tank 6 is omitted in the above structure can be constructed as this example, as shown in Figs. 4, 5, Figure 1 、 2 、4、5, Figure 2 、 4 、5, and other structures in which the transition water tank 6 is omitted in the above structure can be constructed as this example.

[0101] In this example, the liquid outlet element and the heating part share a frame, and the frame has a front panel, on which the liquid outlet holes 7 are arranged, and the liquid outlet holes 7 are in communication with the liquid supply assembly, while the heating part assembly is detachably connected with the frame.

[0102] Embodiment two:

[0103] Compared with embodiment one, the difference between embodiment two and embodiment one is that the heating part is arranged in gap cooperation with the outer periphery of the rotating cylinder 3. The technical effect of this arrangement is that, on the one hand, the rotating resistance of the rotating cylinder 3 is reduced, on the other hand, the abrasion is reduced, and on the other hand, the extrusion on the cleaning part is reduced, which is conducive to avoiding the loss of cleaning liquid caused by the extrusion of the cleaning liquid in the cleaning part.

[0104] Embodiment three:

[0105] Compared with embodiment one, the difference between embodiment three and embodiment one is that the heating part is arranged in both abutting and gap cooperation with the outer periphery of the rotating cylinder 3. The advantage of this arrangement is that it provides great flexibility, and the abutting and gap cooperation can be flexibly arranged according to the characteristics of the cleaning part, thereby optimizing the structure.

[0106] Embodiment four:

[0107] Compared with embodiments one, two and three, the difference between embodiment four and embodiments one, two and three is that the transition water tank 6 is added, and the heating part is used to heat the cleaning liquid supplied to the cleaning part, and at this time, the heating part is preferably arranged in gap cooperation with the outer periphery of the rotating cylinder 3.

[0108] When the transition water tank 6 is added, the structure is: a heating part is arranged in the circumferential direction of the outer periphery of the rotating cylinder 3, the heating part is matched with the gap of the outer periphery of the rotating cylinder 3, 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 for connecting with a water source, the heating element 5 is used for heating the cleaning liquid in the transition water tank 6, and the cleaned liquid after being heated flows to the cleaning part, so that the cleaning part is also heated by the heat brought by the cleaning liquid.

[0109] 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.

[0110] Preferably, the small capacity is within six times of the volume of the supply flow of the cleaning liquid per unit time, including six times. The supply amount of the cleaning liquid per unit time is set according to the cleaning requirement. Generally, reaching or exceeding the supply amount is beneficial to better cleaning performance, but 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 important, as the application 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 foregoing design, the required amount for cleaning use can be better connected, the energy consumption can be balanced, and the program control of opening and closing the heating element 5 can be more controlled. Because the larger the capacity of the transition water tank 6 is, the more difficult it is to control the stability of the working temperature in the dynamic use process. When the capacity of the transition water tank 6 is small and the supply amount is maintained, the balance point is more beneficial to balancing the energy consumption, temperature stability control and cleaning performance.

[0111] The transition water tank 6 is provided with a labyrinth heating flow channel, and the labyrinth heating flow channel is used for rapidly heating the cleaning liquid flowing through the heating element 5 in a short time. In this example, as shown in Figure 7 , the labyrinth heating flow channel of the transition water tank 6 is arranged 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.

[0112] In this example, as shown in Figure 7As 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.

[0113] 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.

[0114] Example Five:

[0115] As shown in Figure 2 , 3 , 4, 5, 6, 7, Figure 7The 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.

[0116] 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.

[0117] In this example, as shown in FIG. 4, 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 5 、 6As shown, the transition water tank 6 has a second opening 10 on the side facing the rotating cylinder 3, allowing the heating element 5 to be exposed. This reduces the obstruction between the heating element 5 and the heat-conducting element 4, making it easier for the heating element 5 to transfer heat through the heat-conducting element 4. This design allows the heating element 5 to be closer to the cleaning section, and also allows the transition water tank 6 to be closer to the cleaning section. This enables the heated cleaning liquid to be transported to the cleaning section over a shorter distance, and also allows the heated cleaning section and the heated cleaning liquid to meet more quickly, thereby minimizing heat loss. This allows for better maintenance of the temperature of the cleaning section with a smaller input heating power, which further improves energy utilization and response performance.

[0118] In this example, as Figure 4 , 5 As shown in Figure 6, to ensure a more uniform output of the heated cleaning liquid, multiple outlet holes 7 are sequentially arranged along the axial direction of the rotating cylinder 3. These outlet holes 7 are connected to the outlet end of the V-shaped labyrinth heating channel via multiple connecting holes 8. Therefore, the multiple outlet holes 7 are located on the upper side of the heat-conducting component 4. The inlet end 11 of the V-shaped labyrinth heating channel is connected to a water source via a pipeline, i.e., connected to the cleaning liquid tank. A water pump can be installed to increase the delivery pressure of the cleaning liquid. Alternatively, the heating component 5 can be shut off promptly by detecting the water level in the cleaning liquid tank and / or the presence of cleaning liquid in the pipeline, thereby achieving higher safety performance, such as anti-dry-burning performance.

[0119] 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.

[0120] Example 6:

[0121] 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.

[0122] Embodiment seven:

[0123] 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. Figure 2 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.

[0124] Embodiment eight:

[0125] 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.

[0126] 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.

[0127] Embodiment nine:

[0128] 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. Figures 8 to 15As shown, in this example, the transition water tank 6 is omitted, and there is no concept of a water tank. The heating unit has a main body 17 or a main body 17 with a flow channel. This main body 17 also serves as a heat conductor 4. The cleaning liquid flows into the flow channel from one end of the main body 17, that is, the liquid inlet connector 16 is connected to one end of the main body 17. The liquid inlet connector 16 communicates with the flow channel and is used to connect the liquid supply assembly. This significantly reduces the overall volume of the heating unit, and since the liquid enters from one end, it eliminates the need for... Figure 3 As shown, liquid enters from the inlet end 11 located at the top center, which also helps to reduce the dimension in the height direction. The aforementioned measures help to reduce the volume of the roller brush or free up more space to install other structures, such as... Figure 10 As shown, because more installation space is freed up, the water pump 26 can also be integrated into the roller brush. In this example, the water pump 26 is located on the side where the liquid inlet connector 16 is located.

[0129] 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.

[0130] Example 10:

[0131] 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.

[0132] In some embodiments, such as Figure 11 As shown, the rotating arrow indicates the rotation direction of the rotating cylinder 3, and the liquid outlet 7 is located on the side of the recess 22 opposite to the rotation direction of the rotating cylinder 3. With this design, the anti-clogging performance is better. In addition, with the aforementioned design, the cleaning part will not be tightly squeezed at the liquid outlet 7, thus facilitating smoother liquid discharge.

[0133] Example 11:

[0134] 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.

[0135] In some embodiments, as shown in Figure 19 、 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.

[0136] 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.

[0137] In understanding the present application, if necessary, the above structure can refer to other embodiments / attached Figure 1 It is understood that the above is not repeated here.

[0138] 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.
