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 with drying structure 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 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 contact.

[0003] In order to improve the cleaning performance, a scheme of spraying cleaning liquid before and after the rolling brush is proposed, and the cleaning liquid is cleaning liquid such as cleaning agent, water and the like, so that the cleaning performance is improved by wetting the rolling brush or the cleaned surface. Although the cleaning performance is improved, the rolling brush needs to be cleaned and dried in time after the cleaning device finishes work, otherwise bacteria are easy to breed and odor is easy to produce. Therefore, the drying structure is set to dry the rolling brush, and the current drying structure is basically a blowing structure, that is, cold air or hot air is blown to the rolling brush for drying. The cold air or hot air is air flow. After this design, on the one hand, the drying is slow, and on the other hand, if hot air is used for drying, cold air flow needs to be heated to form hot air, and then the hot air is transported to the vicinity of the rolling brush through pipeline, and then the rolling brush is dried by the hot air. Energy is converted for many times and transported for a long distance, so the energy consumption is high. Because the energy consumption is high, the drying structure is mostly set on the base, and the base is generally powered by commercial power, not by the battery of the cleaning device.

[0004] Therefore, the applicant continues to conduct in-depth research, and through the unremitting efforts of the applicant, the applicant proposes a rolling brush with drying structure, which is beneficial to reduce energy consumption and improve drying speed. SUMMARY

DETAILED DESCRIPTION

[0071] The following description is presented to enable any person skilled in the art to practice the present application as claimed. The embodiments disclosed in the following description and claims are only examples of the numerous aspects of the present application which are made and given by the written description claimed. Other aspects of the present application sought by the applicants, which are made apparent from this disclosure, are intended to be encompassed by the present application.

[0072] The present application is further described in detail by the following:

[0073] The present disclosure provides a cleaning device including a roller brush having a drying structure, for example, as shown in Figure 1 .

[0074] 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.

[0075] The roll brush with the drying structure provided by the present disclosure comprises a rotating cylinder 3. Of course, the rotating cylinder 3 can be multiple, such as two, three, etc. However, no matter how many rotating cylinders 3 are provided, the scheme of one rotating cylinder 3 can be adjusted or simply copied. The present disclosure also points out that when multiple rotating cylinders 3 are provided, at least one rotating cylinder 3 is provided with the heating part of the present disclosure. When multiple rotating cylinders 3 need to be provided with the heating part, the heating part can be ingeniously arranged between two adjacent rotating cylinders 3, that is, the two adjacent rotating cylinders 3 share one heating part. At this time, the heating part can transfer heat to the corresponding rotating cylinder 3 on both sides, such as two heating members 5 arranged on both sides, or the transition water tank 6 transfers heat to the corresponding rotating cylinder 3 on both sides after being heated.

[0076] 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 scheme of the present disclosure, 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.

[0077] The water or water-related description in the present disclosure does not only refer to water, but also refers to a common name, such as a cleaning liquid tank, which is also commonly referred to as a water tank. The water here refers to a cleaning liquid. The cleaning liquid can be pure water, a mixture of water and a cleaning agent, or a mixture of water and a disinfectant.

[0078] As shown in FIG. 1, Figures 1 to 20 The present disclosure provides a roll brush with a drying structure, which comprises a rotating cylinder 3, a control unit, and a heating part. The heating part is attached to the outer periphery of the cleaning part of the rotating cylinder 3 or is in clearance fit with the outer periphery of the cleaning part of the rotating cylinder 3. The control unit is used to control the heating part to heat and dry the cleaning part.

[0079] In some embodiments, a control unit is separately provided, and a drying function program is arranged in the control unit. When the program is started, the program controls the heating part to emit heat, that is, the control unit controls the heating part to heat and dry the cleaning part.

[0080] In some embodiments, a control unit is shared with a cleaning device, and the control unit has a drying function program. When the user selects or automatically triggers the program, the program controls the heating part to emit heat, that is, the control unit controls the heating part to heat and dry the cleaning part.

[0081] In some embodiments, the control unit is electrically connected with a driving assembly of the rotating drum 3, and when the heating part is heating and drying the cleaning part, the control unit is configured to control the driving assembly to drive the rotating drum 3 to rotate relative to the heating part. The driving assembly, for example, has a motor 29 and a transmission assembly 30, and the control unit controls the motor 29 to rotate, and the motor 29 drives the rotating drum to rotate through the transmission assembly 30.

[0082] In some embodiments, as shown in Figure 2 、 4 , 16, 19, 20, the cleaning device further comprises a scraping assembly and a liquid outlet part, the liquid outlet part is provided with a liquid outlet hole 7 for outputting cleaning liquid to the cleaning part, and the scraping assembly is configured to clean the cleaning part wetted by the cleaning liquid, and the scraping assembly and the liquid outlet part are configured to clean the cleaning part before the heating part heats and dries the cleaning part.

[0083] In some embodiments, the cleaning device further comprises a suction port 13 for sucking away gas generated when the heating part heats and dries the cleaning part.

[0084] In some embodiments, the cleaning device further comprises a scraping and drying assembly, and the scraping and drying assembly is configured to simultaneously scrape and dry the cleaning part when the heating part heats and dries the cleaning part. For example, the scraping and drying assembly is a common scraping plate 12 of the cleaning device.

[0085] In some embodiments, the scraping and drying assembly and the heating part are sequentially arranged along the rotation direction of the rotating drum 3, and the heating part is configured to heat the cleaning part processed by the scraping and drying assembly. For example, the scraping and drying assembly is a common scraping plate 12 of the cleaning device.

[0086] In some embodiments, as shown in Figure 2 、 3 , 10, 17, 18, the cleaning device further comprises 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 sewage from re-polluting the cleaned surface. 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.

[0087] In some embodiments, as shown in Figure 2 、 3 , 10, 17, 18, the dry-structured rolling brush and the cleaning device share the suction port 13, and the suction port 13, the suction pipe 32, a filtering assembly of the cleaning device, and a negative pressure assembly of the cleaning device are sequentially and communicatively arranged.

[0088] In some embodiments, as shown in Figure 2As shown, the squeegee assembly is arranged to avoid the suction port 13. In this way, the squeegee assembly is arranged to avoid the suction port 13, so that the performance of the suction port 13 can be brought into play. The arrangement of avoiding the suction port 13 is not required to be absolute avoidance, but refers to taking certain measures to reduce the shielding of the squeegee assembly to the suction port 13. When the avoidance is to a certain extent, that is, the adverse effect on the suction port 13 is small, such avoidance is also acceptable. Of course, complete avoidance is better.

[0089] In some embodiments, as shown in Figure 2 , the suction port 13 is in front of the squeegee assembly in the rotation direction of the rotating cylinder 3. In this way, the cleaning part has been processed by the suction port 13 before passing through the squeegee assembly, so as to reduce the burden of the squeegee assembly. On the contrary, since the cleaning part has been processed by the suction port 13, the squeegee assembly can better achieve the cleaning effect on the cleaning part after subsequent processing.

[0090] In some embodiments, as shown in Figure 2 , the suction port 13 is located on the upper side of the squeegee assembly. In this way, after being processed by the squeegee assembly, the sewage naturally flows downward, and the suction port 13 can timely suck away the sewage, thereby improving the cleaning efficiency.

[0091] In some embodiments, as shown in Figure 2 , the squeegee assembly adopts a squeegee plate 12. In this way, the structure is relatively simple and reliable, and the sewage can be discharged in the form of scraping by the squeegee plate 12. In the axial direction of the rotating cylinder 3, the cleaning part can be fully cleaned and the sewage can be discharged, and the effect is good.

[0092] 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.

[0093] 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 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. In this way, the structure is more compact.

[0094] In some embodiments, as shown in Figure 3 , 10As shown in Figure 17, the water pump 26 and the motor 29 are arranged on the left and right sides, and the water pump 26 is biased towards the side where the heating part is located. This makes the structure more compact.

[0095] In some embodiments, such as Figure 3 , 10 As shown in Figure 17, the system also includes a roller brush holder 1. The roller brush holder 1 has a mounting part 31 on the rear side of the heating section, in which the water pump 26 and the motor 29 are both mounted. This facilitates better installation of the water pump 26 and the motor 29.

[0096] In some embodiments, such as Figure 10 , 17 As shown, one end of the heating element is connected to a liquid inlet assembly, which is connected to the water pump 26. This allows for a more compact structure. The liquid inlet assembly is, for example, the liquid inlet connector 16.

[0097] In some embodiments, such as Figure 10 , 17 As shown, the liquid inlet assembly has a rearward-facing connector that communicates with the output end of the water pump 26. This facilitates a more compact structure. For example, the connector is connected to the output end of the water pump 26 via a connecting pipe.

[0098] In some embodiments, such as Figures 1 to 18 As shown, the roller brush includes a separable heating section and a liquid outlet section. The heating section includes a heat-conducting element 4 and a heat-discharging element 5. Both the heat-conducting element 4 and the liquid outlet section are circumferentially arranged around the outer periphery of the rotating cylinder 3. The heat-discharging element 5 is thermally connected to the heat-conducting element 4, and the heat-conducting element 4 is in contact with and / or has a clearance fit with the outer periphery of the rotating cylinder 3. The heat-conducting element 4 is used to heat the cleaning section of the rotating cylinder 3 and / or supply the cleaning liquid to the cleaning section. Along the rotation direction of the rotating cylinder 3, the liquid outlet section is located in front of and / or behind the heat-conducting element 4, and the liquid outlet section is used to output the cleaning liquid. With this design, once a blockage occurs, only the liquid outlet section needs to be cleaned, for example... Figure 4 As shown, the roller brush has a transition water tank 6, which has a heating part and a liquid outlet that can be separated from each other. When it is blocked, the transition water tank 6 can be removed and the liquid outlet 7 can be cleaned. There is no need to clean the heating part. When the blockage requires replacement, the heating part can be reused.

[0099] like Figures 8 to 18 As shown, this disclosure provides another type of roller brush, which differs from the roller brush described above in that it uses a different heating element and does not have a transition water tank 6. With this design, if clogging occurs, only the liquid outlet needs to be cleaned, for example... Figure 8 , 9As shown, the liquid outlet part is connected to the lower side of the upper cover 2, and 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, and the liquid outlet part is separated from the heat conducting part 4 through the detachable connection, so that the heat conducting part 4 remains on the roller brush and is not removed, for example, as shown in Figure 8 、 9 , 11, 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 to 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 heated cleaning liquid to the liquid outlet part, for example, as shown in Figure 9 、 13 , 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 part through a detachable connecting pipe 28. The liquid supply assembly supplies cleaning liquid into the flow channel through the liquid inlet 15 of the flow channel. After the liquid outlet part 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 part needs to be replaced, and the heating part remains on the roller brush frame 1 and does not need any operation and replacement. That is, the heating part can be reused.

[0100] Of course, the liquid outlet hole 7 can also be integrally arranged, for example, as shown in Figure 19 , the present disclosure provides another heating part, in which the liquid outlet hole 7 is integrally arranged on the main body 17 of the heating part.

[0101] In some embodiments, the liquid outlet part is provided with a liquid outlet flow channel 14, and each liquid outlet hole 7 is communicated with the liquid outlet flow channel 14.

[0102] 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 can be inclined to the axis direction of the rotating cylinder 3. The main body or the transition water tank is provided with a 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 is required to 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.

[0103] In some embodiments, in order to facilitate production and assembly, the following design is made, for example, as shown in Figure 10 、 12The heating part has a liquid inlet connector 16, a bracket 18, and a main body 17 extending along the axis of the rotating cylinder 3. The main body 17 and the bracket 18 are distributed and connected along the front-rear direction. The main body 17 is provided with a flow channel extending along the axis 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 in communication with the flow channel. The liquid inlet connector 16 is used to connect a 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 in communication with the flow channel, which means that the liquid outlet 23 is in communication with the inlet of the flow channel. The bracket 18 is used. After the design, the thickness of the main body 17 can be further reduced due to the support of the bracket 18, thereby further improving the energy utilization rate.

[0104] In some embodiments, the assembly sequence of the heating part can be: the main body 17 is inserted along one end of the bracket 18, so that the main body 17 and the bracket 18 are sleeved along the axis of the rotating cylinder 3, and then the liquid inlet connector 16 is connected to one end of the bracket 18 and / or the liquid inlet connector 16 is connected to one end of the main body 17, for example as shown in Figure 14 The liquid inlet connector 16 is provided with two screw through holes 24. Correspondingly, one end of the main body 17 is also provided with two threaded holes 25. The screw passes through the screw through hole 24 and the threaded hole 25 to connect and fix the liquid inlet connector 16 to one end of the main body 17. At the same time, the side surface of the liquid inlet connector 16 located on one side of the bracket 18 closes the opening of one end of the bracket 18. The side surface of the liquid inlet connector 16 located on one side of the bracket 18 is provided with a sealing gasket. The side surface of the liquid inlet connector 16 located on one side of the bracket 18 is tightly fixed to the end surface of 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. Correspondingly, the other end of the main body 17 is also provided with a threaded hole 25. 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 12 、 13 The bracket 18 has a recessed cavity. The upper edge and the lower edge of the recessed cavity are respectively sleeved and matched with the upper edge and the lower edge of the main body 17 through the concave-convex sleeving structure. In this example, as shown in Figure 16 The recess of the concave-convex sleeving structure is arranged on the upper edge and the lower edge of the main body 17. The upper edge and the lower edge of the recessed cavity are correspondingly provided with the protrusion 19 of the concave-convex sleeving structure. Such a structure design makes assembly very convenient. In addition, the support for the main body 17 is more reliable.

[0105] In some embodiments, the flow channel in the main body 17 is not one but multiple, which is conducive to forming a labyrinth flow channel, as shown in Figure 13 、 15As shown, the flow channels in the main body 17 are four, 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 transition groove 20 is processed at both ends of the main body 17, which is used to communicate the adjacent flow channels. For the closure of the transition groove 20, for example, a sealing member can be arranged at each end of the main body 17. For example, a protruding part 21 is arranged at one side of the liquid inlet joint 16 of the support 18 and at the other end of the support 18 as a sealing member. The protruding part 21 at the other end of the support 18 can also be used as a fixing part of the other end of the main body 17 after the main body 17 is sleeved with the support 18. Thus, the production and manufacturing are greatly facilitated.

[0106] 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. The labyrinth flow channel is provided in the main body 17 and extends back and forth along the axis direction of the rotating cylinder from one end of the arc-shaped structure, for example, forming the serpentine labyrinth flow channel.

[0107] 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. This is beneficial for protecting the heating element 5 and simplifying the production and manufacturing.

[0108] In some embodiments, the back surface of the main body 17 is provided with a mounting groove in which the heating element 5 is arranged. This is beneficial for reducing the overall thickness of the assembly formed after the main body 17 is connected with the heating element 5 and wrapping the heating element 5 to make more heat conduct to the main body 17.

[0109] 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 coated on the back surface of the main body 17 and sintered. This makes the heating element 5 more firmly combined with the main body 17 and substantially integrated. This design is beneficial for reducing the loss of heat conduction and reducing the overall thickness of the assembly formed after the main body 17 is connected with the heating element 5.

[0110] 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 for saving energy, improving the utilization rate of heat energy and reducing waste.

[0111] 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.

[0112] The following examples further illustrate the technical solutions of the present disclosure:

[0113] Embodiment one:

[0114] The rotating brush of the present disclosure includes a rotating cylinder 3, and a heating portion is arranged in the circumferential direction of the outer periphery of the rotating cylinder 3. The heating portion is attached to the outer periphery of the rotating cylinder 3, and the heating portion 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 the cleaning portion and is transmitted to the cleaning portion, the distance of heat transmission is zero, the use efficiency is high, the waste of heat is reduced, and the effective utilization rate of heat is improved.

[0115] The heating portion includes a heat conduction element 4 and a heating element 5. The heat conduction element 4 is arranged in the circumferential direction of 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 transmitted 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 transmitted more comprehensively, thereby facilitating the protection of the heating area of the cleaning portion and facilitating the reduction of the installation number of the heating element 5 to avoid excessive weight.

[0116] The rotating brush further includes a rotating 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, i.e., the rotating brush can be directly used after the replacement, which greatly facilitates the use of users.

[0117] Preferably, as shown in Figure 1 , 2 , 3, the rotating 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, i.e., 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.

[0118] 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.

[0119] The heating body comprises continuous heat-conducting members 4 arranged in the axial direction and non-continuous heating members 5, the heat-conducting members 4 are arranged at the outer side, the heating members 5 are arranged at the inner side, and the heat-conducting members 4 separate the heating members 5 from the rotating cylinder 3. In this way, on the one hand, the number of the heating members 5 arranged and installed is simplified, and on the other hand, the heat-conducting members 4 separate the heating members 5 from the rotating cylinder 3, which is beneficial to protecting the heating members 5 and prolonging the service life.

[0120] The heating part is continuously arranged in the axial direction of the rotating cylinder 3. This design can make the cleaning part uniformly heated, which is beneficial to the drying performance.

[0121] The heat insulation structure is further arranged, which is used for transmitting most of the heat generated by the heating part to the cleaning part. The heat insulation structure is, for example, a heat insulation layer arranged at the rear and around the heating members 5. In this way, the heat of the heating members 5 is mainly transmitted to the front side, that is, mainly transmitted to the heat-conducting members 4, and then transmitted to the cleaning part by the heat-conducting members 4. This design is beneficial to reducing waste and improving heat utilization rate.

[0122] The side of the heating part facing the rotating cylinder 3 comprises an arc-shaped structure arranged around the rotating direction of the rotating cylinder 3. In this example, the heat-conducting members 4 are arranged in an arc-shaped structure, that is, the heat-conducting members 4 are concave arc-shaped plates. After this design, the concave arc-shaped plates match the outer circumferential surface of the cleaning part, which is beneficial to the smooth rotation of the cleaning part and the good adhesion between the concave arc-shaped plates and the cleaning part, thereby improving the heat transfer efficiency.

[0123] In this example, the transition water tank 6 is not arranged, and other structures in which the transition water tank 6 is omitted in the above structure can be constructed in this example, which can be referred to the drawings of the heat-conducting members 4, the heating members 5 and the frame 2. Figure 1 、 2 、4、5, Figure 2 、 4 、5.

[0124] In this example, the liquid outlet part and the heating part share one frame, the frame has a front panel, each liquid outlet hole 7 is arranged on the front panel and communicates with the liquid supply assembly, and the heating part assembly is detachably connected with the frame.

[0125] Embodiment two:

[0126] Compared with embodiment one, the difference of embodiment two is that the heating part is matched with the gap between the outer circumferences of the rotating cylinder 3. The technical effect of this design is that on the one hand, the rotating resistance of the rotating cylinder 3 is reduced, and on the other hand, the abrasion is reduced.

[0127] Embodiment three:

[0128] Compared with embodiment one, the difference of embodiment three is that the heating part is matched with both the abutment and the gap between the outer circumferences of the rotating cylinder 3. The advantage of this design is that great flexibility is provided, and the abutment and the gap are flexibly arranged according to the characteristics of the cleaning part, thereby optimizing the structure.

[0129] Example four:

[0130] Example four is different from example one, two and three in that a transition water tank 6 is added, and a heating part is used to heat the cleaning liquid supplied to the cleaning part.

[0131] When the transition water tank 6 is added, the structure is that 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 to be connected with the water source, the heating element 5 is used to heat the cleaning liquid in the transition water tank 6, and the heated cleaning liquid flows to the cleaning part, so that the cleaning part is also heated by the heat brought by the cleaning liquid.

[0132] 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.

[0133] 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 needs. In general, reaching or exceeding the supply amount is conducive 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 invention says "the transition water tank 6 adopts a small capacity, and the capacity of the small capacity is less than the capacity of the water source." After the foregoing design, it can better connect the amount required for cleaning use, balance the energy consumption, and also be more conducive to controlling the program control of the opening and closing of the heating element 5. 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, and the supply amount is maintained, the balance point at this time is more conducive to balancing the energy consumption, temperature stability control, and cleaning performance of the three elements.

[0134] The transition water tank 6 is provided with a labyrinth heating flow channel, which is used to make the heating element 5 quickly heat the cleaning liquid flowing therethrough in a short time. Figure 7 As shown in the figure, the labyrinth heating flow channel of the transition water tank 6 is arranged as a V-shaped labyrinth heating flow channel, and in order to better match the rotating cylinder 3, the overall shape of the transition water tank 6 is also roughly V-shaped.

[0135] In this example, as shown in the figure, the labyrinth heating flow channel of the transition water tank 6 is arranged as a V-shaped labyrinth heating flow channel, and in order to better match the rotating cylinder 3, the overall shape of the transition water tank 6 is also roughly V-shaped. 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 direction 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, and on the other hand, the upward flow on the outlet side makes it easier for the heat to flow upward, so that the cleaning liquid can better carry away the heat generated by the heating element 5. In addition, due to the V-shaped structure, the left and right flow channels are relatively close, so that when the heating element 5 generates heat, the cleaning liquid in the upward flow channel on the right side is preheated, and then when it flows upward on the outlet side, the cleaning liquid can be heated to a higher temperature more quickly, 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, heating elements 5 can also be arranged in the upward flow channel on the right side.

[0136] After the above design, the cleaning liquid in the transition water tank 6 is used for cleaning after heating, without the need for long-distance transportation, greatly reducing waste, and avoiding the safety hazards caused by long-distance transportation.

[0137] Example Five:

[0138] As shown in Figure 2 , 3 , 4, 5, 6, 7, Figure 7 The arrow in the middle indicates the flow direction of the cleaning liquid. Compared with Example Four, Example Five not only increases the transition water tank 6, but also uses the heating part to heat the cleaning part of the rotating cylinder 3. In this example, specifically, the heating element 5 is arranged in the circumferential direction around the outer periphery of the rotating cylinder 3. The heating element 5 not only heats the cleaning liquid, but also includes a heat-conducting element 4 arranged in the circumferential direction around the outer periphery of the rotating cylinder 3. The heating element 5 not only heats the cleaning liquid, but also heats the cleaning part of the rotating cylinder 3 through the heat-conducting element 4.

[0139] The technical effects of the design are as follows: first, the heat generated in the front-rear direction of the heating element 5 can be more quickly applied to the cleaning part, that is, the front side of the heating element 5 is the cleaning part, and the rear side of the heating element 5 is the cleaning liquid. The heat generated in the front-rear direction of the heating element 5 is more efficiently utilized. This is because the front side of the heating element 5 directly heats the cleaning part, without the need for the cleaning liquid in the transition water tank 6 to carry heat to heat the cleaning part again, that is, one heat conversion is reduced. In addition, the front side of the heating element 5 directly heats the cleaning part, which is also beneficial to improve the compactness of the structure. Since the rear side of the heating element 5 cannot directly heat the cleaning part, the cleaning liquid in the transition water tank 6 carries heat to superimpose the cleaning part preheated by the front side of the heating element 5, so that the heat generated by the heating element 5 is more efficiently utilized. Because the heat is more efficiently utilized, it is very beneficial to shorten the heating time, so that the working temperature can be reached in a short period of time. Second, while achieving the purpose of more efficient utilization of heat, it is also beneficial to further improve the compactness of the structure, thereby further reducing the thickness of the transition water tank 6. Third, when designing the V-shaped labyrinth heating flow channel, only the heating element 5 arranged in the left-to-top flow channel of the V-shaped labyrinth heating flow channel can achieve the purpose of faster heating, without the need to arrange the heating element 5 in the left and right flow channels of the V-shaped labyrinth heating flow channel, so that the overall structure is more optimized. At the same time, this design also avoids the waste of heat caused by arranging the heating element 5 in the left and right flow channels of the V-shaped labyrinth heating flow channel. The reason is that if the heating element 5 is arranged in the top-to-bottom flow channel on the right side of the V-shaped labyrinth heating flow channel, the heat transfer of the heating element 5 to the right side will be increased, and because of the speed of heat absorption by the cleaning liquid, the heat cannot be absorbed and removed in time, resulting in heat loss. The above-mentioned scheme avoids this situation.

[0140] In this example, as shown in Figure 5 、 6 , the transition water tank 6 is provided with a second opening 10 on the side facing the rotating cylinder 3. The second opening 10 is used to expose the heating element 5, thereby reducing the obstruction between the heating element 5 and the heat-conducting element 4, and more beneficially allowing the heating element 5 to transfer heat through the heat-conducting element 4. This design allows the heating element 5 to be closer to the cleaning part, and also allows the transition water tank 6 to be closer to the cleaning part, so that the heated cleaning liquid can be transported to the cleaning part in a shorter distance, and the heated cleaning part and the heated cleaning liquid meet faster, thereby minimizing heat loss, allowing smaller heating power to be input to better maintain the temperature of the cleaning part, that is, further improving energy utilization and further improving response performance.

[0141] In this example, as shown in Figure 4 、 5As shown in Fig. 6, in order to more evenly output the heated cleaning liquid, a plurality of liquid outlet holes 7 are sequentially arranged along the axial direction of the rotating cylinder 3, the liquid outlet holes 7 are communicated with the outlet end of the V-shaped labyrinth heating flow channel through a plurality of communication holes 8, and therefore the plurality of liquid outlet holes 7 are located on the upper side of the heat conduction member 4. The liquid inlet end 11 of the V-shaped labyrinth heating flow channel is communicated with the water source through a pipeline, that is, communicated with the cleaning liquid tank. A water pump can be arranged to increase the delivery pressure of the cleaning liquid. The heating member 5 can also be closed in time by detecting the water level of the cleaning liquid tank and / or whether the pipeline has cleaning liquid, thereby achieving higher safety performance, such as dry burning prevention performance.

[0142] For the case of simultaneous heating, other schemes can also be used, such as the heating member 5 directly heating the cleaning part of the rotating cylinder 3 while heating the cleaning liquid, and again, the heating member 5 can heat the cleaning part of the rotating cylinder 3 through the heated transition water tank 6 while heating the cleaning liquid, because the transition water tank 6 also becomes hot after the cleaning liquid is heated.

[0143] When the cleaning of the cleaning part is completed, the heating member 5 is continuously maintained in an open state, so that the heat of the heating member 5 is used to complete the drying of the cleaning part.

[0144] Embodiment six:

[0145] Embodiment six differs from embodiment five in that it further comprises a dirt scraping plate 12, which scrapes dirt from the cleaning part. The dirt scraping plate 12 scrapes the sewage and dirt on the cleaning part together, and then the sewage is sucked away by the suction port 13 near the dirt scraping plate 12. In embodiment six, along the rotating circumferential direction of the rotating cylinder 3, the transition water tank 6 is located on the rear side of the dirt scraping plate 12, that is, the cleaning part is scraped first, and then heated and dried. In this way, the heat can be more effectively used, because if the sewage is not removed in time by the dirt scraping plate 12, the part of the cleaning part where the sewage is located (the part of the cleaning part that is contaminated) will reabsorb heat, and the part of the cleaning part that is contaminated is not conducive to hygiene. Therefore, through the above design, the heat is more effectively used, thereby improving hygiene and drying speed, and further reducing waste.

[0146] Embodiment seven:

[0147] Embodiment seven differs from the above-mentioned embodiments in 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 that 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 above-mentioned embodiments, the heating part is arranged along the axial direction of the rotating cylinder 3 and along the circumferential direction of the rotating cylinder 3. Figure 2The structure shown in Embodiment 7 is a heating element. In Embodiment 7, at least one heating element is added sequentially along the circumference of the rotating cylinder 3, forming a structure with two heating elements. This structure in Embodiment 7 is advantageous for reaching the required temperature more quickly, and if necessary, it can also reach a higher temperature. However, the structure is relatively large and the energy consumption is high. Embodiment 7 is more suitable for certain applications that require higher temperatures.

[0148] Example 8:

[0149] The difference between Embodiment 8 and the above embodiments is that it also includes a temperature sensor, which is used to detect the temperature of the heating part and / or the temperature of the cleaning part and / or the temperature of the cleaning liquid supplied to the cleaning part and / or the temperature of the surface being cleaned.

[0150] By setting up a temperature sensor, the technical benefits are twofold: firstly, it provides a structural foundation for more intelligent heating control, and combined with the control program, it helps to further refine energy consumption control; secondly, it can further improve safety, adding an extra layer of protection.

[0151] Example 9:

[0152] like Figures 8 to 15 As 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.

[0153] 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.

[0154] Example 10:

[0155] Compared to Example 9, for example Figure 11As shown, the liquid outlet part located at one side of the rotating cylinder 3 is provided with a recess 22 extending along the axis direction of the rotating cylinder 3, and the liquid outlet hole 7 is arranged in the recess 22. In this way, the liquid outlet hole 7 is not easy to be contaminated, and the liquid outlet is smooth.

[0156] In some embodiments, as shown in Figure 11 The rotating arrow represents the rotating direction of the rotating cylinder 3, and the liquid outlet hole 7 is located on the side surface of the recess 22 opposite to the rotating direction of the rotating cylinder 3. In this way, the anti-blocking performance is more excellent, and in addition, according to the foregoing design, the cleaning part is not tightly pressed at the liquid outlet hole 7, so that the liquid outlet is more smooth.

[0157] Embodiment eleven:

[0158] Compared with embodiment ten, for example Figure 19 、 20 As shown, the difference lies in that it further comprises a scraping plate 12, the scraping plate 12 is the scraping assembly, and the liquid outlet hole 7 and the scraping plate 12 are integrally arranged on the heat conduction piece 4, that is, integrally arranged on the main body 17 in this example. Specifically, the liquid outlet hole 7 is located near the upper edge of the main body 17, and the scraping plate 12 is located near the lower edge of the main body 17. The scraping plate 12 scrapes the cleaning part, that is, scrapes the sewage and dirt on the cleaning part, and then the sewage and dirt are sucked away by the suction port 13 near the scraping plate 12. Due to the integrated arrangement, the scraping plate 12 can also transfer part of the heat, that is, the hot scraping plate 12. The hot scraping plate 12 has better cleaning effect when processing the cleaning part than the cold scraping plate 12.

[0159] In some embodiments, as shown in Figure 19 、 20 The scraping plate 12 is integrally arranged with the heat conduction piece 4, so that it is easier to conduct heat to the scraping plate 12, reduce heat waste, and facilitate the simplification of the structure and the production and manufacturing.

[0160] When the cleaning of the cleaning part is completed, the heating piece 5 is continuously maintained to be turned on, so that the heat of the heating piece 5 is used to dry the cleaning part.

[0161] Embodiment twelve:

[0162] When the cleaning of the cleaning part is completed, it is desired that the liquid outlet hole 7 no longer discharges liquid. In order to simply control the liquid outlet state of the liquid outlet hole 7, a flow passage on-off assembly having two states of closed state and open state is further included. The flow passage on-off assembly is arranged on the flow passage for supplying cleaning liquid. When the flow passage on-off assembly is in the closed state, the part of the flow passage before the flow passage on-off assembly is not communicated with the liquid outlet hole 7. When the flow passage on-off assembly is in the open state, the part of the flow passage before the flow passage on-off assembly is communicated with the liquid outlet hole 7. The liquid outlet of the liquid outlet hole 7 is controlled by the flow passage on-off assembly.

[0163] In some embodiments, as shown in Figs. 19, 20 and 21, the present disclosure provides a heating part, and the outlet flow channel 14 is provided with a flow channel on-off assembly. Figure 8 、 9 In some embodiments, as shown in Figs. 19, 20 and 21, the present disclosure provides a heating part, and the outlet flow channel 14 is provided with a flow channel on-off assembly.

[0164] In some embodiments, as shown in Figs. 19, 20 and 21, the present disclosure provides a heating part, and the outlet flow channel 14 is provided with a flow channel on-off assembly. Figure 21 、 22 In some embodiments, as shown in Figs. 19, 20 and 21, the present disclosure provides a heating part, and the outlet flow channel 14 is provided with a flow channel on-off assembly.

[0165] In some embodiments, as shown in Figs. 19, 20 and 21, the present disclosure provides a heating part, and the outlet flow channel 14 is provided with a flow channel on-off assembly. Figure 21 、 22 In some embodiments, as shown in Figs. 19, 20 and 21, the present disclosure provides a heating part, and the outlet flow channel 14 is provided with a flow channel on-off assembly.

[0166] In some embodiments, as shown in Figs. 19, 20 and 21, the present disclosure provides a heating part, and the outlet flow channel 14 is provided with a flow channel on-off assembly. Figure 21 、 22 In some embodiments, as shown in Figs. 19, 20 and 21, the present disclosure provides a heating part, and the outlet flow channel 14 is provided with a flow channel on-off assembly.

[0167] In some embodiments, the flow channel on-off assembly is a solenoid valve structure, and the two states are switched by electromagnetic force.

[0168] In some embodiments, the flow channel on-off assembly is a duckbill valve, and when the pressure of the cleaning liquid at the outlet end is higher than the opening pressure required by the duckbill valve, the duckbill valve is opened to make the flow channel on-off assembly in an open state. The foregoing structure is relatively simple and reliable for controlling the outlet hole 7, for example, the water pump 26 generates pressure, and the opening of the duckbill valve is controlled by the change of the pressure of the cleaning liquid.

[0169] The flow channel on-off assembly can also be other structures, as long as it is applicable to the present disclosure.

[0170] In some embodiments, the scheme for accelerating drying is to blow air to the cleaning part, that is, a blowing structure is provided, and the blowing structure blows air to the cleaning part. After such design, the gas generated by the heating part is quickly blown away, thereby facilitating the acceleration of drying.

[0171] In some embodiments, the negative pressure component of the cleaning device serves as the blowing structure. Generally, the negative pressure component is used as suction.
