In some embodiments, for example, as shown in fig. 23, the present disclosure provides a liquid outlet portion, which includes a body extending along an axial direction of a rotating cylinder 3, the body is provided with a liquid outlet channel 14 disposed along the axial direction, a start point and an end point of the liquid outlet channel 14 along the axial direction are respectively two ends of the liquid outlet channel 14, one side of the body located on the rotating cylinder 3 is provided with a plurality of liquid outlet holes 7 sequentially disposed along the liquid outlet channel 14, each liquid outlet hole 7 is respectively communicated with the liquid outlet channel 14, one of the two ends is used as a liquid inlet 15, and a size of each liquid outlet hole 7 gradually increases along the axial direction from the liquid inlet 15 to the other end of the liquid outlet channel 14.

After adopting above-mentioned structure, this disclosure has following advantage: since the size of each liquid outlet hole 7 is gradually increased along the axial direction of the rotary cylinder 3 from the liquid inlet of the liquid outlet channel 14 to the other end of the liquid outlet channel 14, when water is discharged, the water pressure near the liquid inlet 15 is high, so the flow rate of the liquid outlet hole 7 near the liquid inlet 15 is high, when the liquid outlet hole 7 near the liquid inlet 15 is small, the flow cross section is small, so although the flow rate is high, the water yield is reduced compared with the original structure, while the flow rate of the liquid outlet hole 7 at a slightly distant point is relatively low, but the water yield is increased compared with the original structure due to the enlarged hole, based on the above scheme, the wetting degree of the cleaning part of the rotary cylinder 3 is uniform, therefore, the technical scheme of feeding liquid from one end of the two ends of the liquid outlet channel is adopted, the wetting degree of the cleaning part of the rotary cylinder 3 is also uniform, and the structure is simple, thereby providing a favorable precondition for reducing the volume of the rolling brush.

The heating portions are continuously provided in the axial direction of the rotary cylinder 3. By the design, the cleaning part can be uniformly heated, and the drying performance is facilitated.

The heating device also comprises a heat insulation structure, and the heat insulation structure is used for transferring most of heat generated by the heating part to the cleaning part. The heat insulating structure is, for example, a heat insulating layer provided at the rear and around the heating member 5, so that the heat of the heating member 5 is mainly transferred to the front side, that is, mainly to the heat conductive member 4, and the heat conductive member 4 transfers the heat to the cleaning portion. The design is favorable for reducing waste and improving the heat utilization rate.

The side of the heating part facing the rotary cylinder 3 comprises an arc structure arranged around the rotary direction of the rotary cylinder 3, in this case, the heat conducting member 4 is arranged in an arc structure, that is, the heat conducting member 4 is a concave arc plate. After designing like this, concave arc matches with clean portion outer peripheral face, is favorable to clean portion smooth and easy rotation on the one hand, and on the other hand is favorable to concave arc and the good laminating of clean portion to promote heat transfer efficiency.

In this example, the transitional water tank 6 is not provided, the above structure can be shown in fig. 1, 2, 4 and 5, and other structures in fig. 2, 4 and 5 can be configured without the transitional water tank 6.

In this embodiment, the liquid outlet portion and the heating portion share a single frame, the frame has a front panel, each liquid outlet hole 7 is provided on the front panel, each liquid outlet hole 7 is communicated with the liquid supply assembly, and the heating portion assembly is detachably connected with the frame.

Example two:

the second embodiment is different from the first embodiment 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.

After adding transition water tank 6, the structure is: the heating portion includes transition water tank 6, and the heating member 5 of heating portion is arranged in transition water tank 6, and transition water tank 6 is used for being connected with the water source, and heating member 5 is arranged in heating the cleaning liquid in transition water tank 6, and the cleaning liquid flow after the heating flows to cleaning portion, and like this, cleaning portion is also heated by the heat that cleaning liquid took.

The transition tank 6 uses a small volume that is less than the volume of the water source.

Preferably, the small volume is within six times, including six times, the volume of the cleaning liquid supply flow rate per unit time. The supply of cleaning liquid per unit time is set according to the cleaning needs, and generally, reaching or exceeding this supply is favorable for better cleaning performance, but if the capacity of the transition water tank 6 is not limited, it will cause drawbacks, so the capacity of the transition water tank 6 is also important, just like the utility model discloses a "the transition water tank 6 adopts the small capacity, and this small capacity's capacity is less than the capacity of water source. ". According to the aforesaid design after, can link up the required volume of clean use so better, balanced energy consumption simultaneously, also more be favorable to controlling program control switching heating member 5 in addition, this is because the transition water tank 6 capacity is bigger, in the dynamic use in-process, to operating temperature's stability control more difficult, when transition water tank 6 capacity is less, can maintain the supply to the supply volume again simultaneously, the balance point then this moment, then more be favorable to balanced energy consumption, temperature stability control, three key elements of cleaning performance.

A labyrinth heating flow passage is arranged in the transition water tank 6 and is used for enabling the heating element 5 to rapidly heat the flowing cleaning liquid in a short time. In this example, as shown in fig. 7, the labyrinth heating flow path of the transition water tank 6 is provided as a V-shaped labyrinth heating flow path, and the entire outer shape of the transition water tank 6 is also substantially V-shaped in order to match the rotary cylinder 3 more favorably.

In this example, as shown in fig. 7, the cleaning liquid in the V-shaped labyrinth heating flow channel flows in from the upper right end of the V-shaped labyrinth heating flow channel and then flows out to the upper left end of the V-shaped labyrinth heating flow channel along the V-shape, so that the flow distance is lengthened to allow the cleaning liquid to absorb more time the heat generated by the heating element 5, and the cleaning liquid flows from bottom to top on the outlet side to allow the cleaning liquid to better take away the heat generated by the heating element 5 because the heat flows more easily upward. In addition, because the V-shaped flow channels on the left side and the right side are relatively close, when the heating element 5 generates heat, the cleaning liquid in the flow channel from top to bottom on the right side is preheated, and when the cleaning liquid flows from bottom to top on the outlet side, the cleaning liquid can be heated to a higher temperature more quickly, so that the heating time is shortened. In addition, the V-shaped labyrinth heating flow channel is adopted, so that the whole structure is very compact. If the heating time needs to be further shortened, the heating elements 5 can be arranged in the right-side flow passage from top to bottom at the same time.

After the design, the cleaning liquid in the transition water tank 6 is used for the cleaning part after being heated, long-distance conveying is not needed, waste is greatly reduced, and in addition, potential safety hazards caused by long-distance conveying are avoided.

As shown in fig. 2, 3, 4, 5, 6 and 7, an arrow in fig. 7 indicates a flow direction of the cleaning liquid, and the cleaning portion of the rotary cylinder 3 is heated by the heating portion, in this example, specifically, the heating member 5 is provided around the circumferential direction of the outer periphery of the rotary cylinder 3, the heating member 5 heats the cleaning liquid and also includes the heat-conductive member 4, the heat-conductive member 4 is provided around the circumferential direction of the outer periphery of the rotary cylinder 3, and the heating member 5 heats the cleaning portion of the rotary cylinder 3 by the heat-conductive member 4 while heating the cleaning liquid.

The technical effect that design has like this is: firstly, the heat generated in the front-back direction of the heating member 5 can be applied to the cleaning part more quickly, that is, the front side of the heating member 5 is the cleaning part, and the back side of the heating member 5 is the cleaning liquid, so the heat generated in the front-back direction of the heating member 5 can be more efficiently utilized, because the front side of the heating member 5 directly heats the cleaning part, the cleaning part is not required to be heated by the heat carried by the cleaning liquid in the transition water tank 6, that is, one-time heat conversion is reduced, and the front side of the heating member 5 directly heats the cleaning part, the advantage of being beneficial to improving the structure compactness is also achieved, and the back side of the heating member 5 can not directly heat the cleaning part, so the heat carried by the cleaning liquid in the transition water tank 6 is superposed on the cleaning part preheated by the front side of the heating member 5, so the heat generated by the heating member 5 is more efficiently utilized, the advantage of being very beneficial to shortening the heating time, and the working temperature can be reached in a short time; secondly, the purpose that heat is utilized more efficiently is achieved, and meanwhile, the structure compactness is further improved, so that the thickness size of the transition water tank 6 is further reduced; thirdly, when designing the V-maze heating channel, the purpose of faster heating can be realized only by arranging the heating member 5 in the channel from bottom to top on the left side of the V-maze heating channel, and the heating member 5 does not need to be arranged in the channels on the left and right sides of the V-maze heating channel, so that the whole structure is optimized, and meanwhile, the heat waste caused by arranging the heating member 5 in the channels on the left and right sides of the V-maze heating channel is avoided.

In some embodiments, as shown in fig. 5 and 6, a second opening 10 is provided on a side of the transition water tank 6 facing the rotary drum 3, and the second opening 10 is used for exposing the heating element 5, so as to reduce the obstruction with the heat conducting element 4, and further facilitate the heat transfer from the heating element 5 to the heat conducting element 4. Design like this can make heating member 5 be close to the cleaning part more, also make transition water tank 6 be close to the cleaning part more simultaneously, thereby make the cleaning liquid after the heating can be carried the cleaning part by shorter distance, also make the cleaning part after the heating meet with the cleaning liquid after the heating more fast, thereby reduce thermal loss to the utmost, make the less heating power of input, just can maintain the temperature of cleaning part better, that is to say further improve energy utilization, further promote response performance simultaneously.

In some embodiments, as shown in fig. 4, 5 and 6, in order to output the heated cleaning liquid more uniformly, a plurality of liquid outlet holes 7 are sequentially formed along the axial direction of the rotary cylinder 3, and 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, so that the plurality of liquid outlet holes 7 are located at the upper side of the heat conducting member 4. The liquid inlet end 11 of the V-shaped labyrinth heating flow channel is communicated with a water source, namely a cleaning liquid tank, through a pipeline. A water pump may be provided to increase the delivery pressure of the cleaning liquid. It is also possible to turn off the heating member 5 in time by detecting the water level of the cleaning liquid tank and/or whether the cleaning liquid is present in the pipe, thereby achieving higher safety performance, such as dry burning prevention performance.

Other solutions are possible for the simultaneous heating, for example, the heating element 5 heats the cleaning part of the rotary drum 3 directly by the heating element 5 while heating the cleaning liquid, and for example, the heating element 5 heats the cleaning part of the rotary drum 3 by the heated transition water tank 6 since the transition water tank 6 is also heated after heating the cleaning liquid while heating the cleaning liquid.

When the cleaning of the surface to be cleaned is completed or the cleaning of the cleaning part itself is completed, the heating member 5 is continuously maintained to be turned on, thereby completing the drying of the cleaning part using the heat of the heating member 5.

Example three:

in the third embodiment, the third embodiment further comprises a dirt scraping plate 12, and the dirt scraping plate 12 scrapes dirt on the cleaning part, that is, the dirt is scraped off together with the dirt on the cleaning part, and then the dirt is sucked by the suction opening 13 near the dirt scraping plate 12. In the third embodiment, the transition water tank 6 is located at the rear side of the dirt scraping plate 12 along the rotation circumferential direction of the rotary cylinder 3, i.e. the cleaning part scrapes dirt first and then heats the cleaning part again, so that heat can be used more effectively, because if the dirt is not removed through the dirt scraping plate 12 in time, the part of the cleaning part where the dirt is located (the part of the polluted cleaning part) will absorb heat again and is wasted. And the contaminated part of the cleaning portion is not conducive to hygiene, so through the above design, the heat is used more effectively, thereby improving hygiene, in addition, when the cleaning portion drying procedure is performed, it is beneficial to improve drying speed, further reducing waste.

Example four:

compared with the above embodiments, the difference of the fourth embodiment is that a plurality of heating portions are provided, each heating portion is provided along the axial direction of the rotary cylinder 3, the axial length of each heating portion is substantially equal to that of the cleaning portion, and each heating portion is further provided in sequence along the circumferential direction of the rotary cylinder 3, that is, compared with the structure of one heating portion shown in fig. 2, at least one heating portion is further added in sequence along the circumferential direction of the rotary cylinder 3 to form a structure of two heating portions.

Example five:

fifth embodiment is different from the above-described embodiments in that a temperature sensor for detecting a temperature of the heating part and/or a temperature of the cleaning liquid supplied to the cleaning part and/or a temperature of the surface to be cleaned is further included.

Through setting up temperature sensor, the technical effect that can obtain is: on the one hand, a structural basis is provided for more intelligently controlling heating, and the control program is combined to help further fine control of energy consumption, on the other hand, the safety can be further improved, and one guarantee is added for safety.

Example six:

as shown in fig. 8 to 15, the transitional water tank 6 is eliminated in this example, and there is no concept of a water tank, the heating part has a main body 17 or a main body 17 provided with a flow passage, the main body 17 is also used as a heat conducting member 4, the cleaning liquid flows into the flow passage from one end of the main body 17, namely, an inlet connector 16 is connected with one end of the main body 17, the inlet connector 16 is communicated with the flow passage, the inlet connector 16 is used for connecting a liquid supply assembly, so that the whole volume of the heating part is obviously reduced, and the liquid is supplied from one end, and the liquid is not required to be supplied from an inlet end 11 at the upper middle position as shown in fig. 3, so that the height direction size is also favorably reduced, the measures are favorable for reducing the volume of the roller brush or making more space for installing other structures, for example, as shown in fig. 10, a water pump 26 can be integrated in the roller brush because more installation space is made, in this example, the water pump 26 is positioned at the side where the inlet connector 16 is positioned.

In this example, the main body 17 heats not only the cleaning liquid, but also the main body 17 itself conducts heat, so that the main body 17 can be used to directly heat the cleaning portion, that is, the main body 17 is also used as the heat conductive member 4, and the temperature rise of the cleaning portion is accelerated. With this arrangement, not only the response is fast, but also since heat is mainly used for the cleaning portion by heating the cleaning liquid and directly heating the cleaning portion through the main body 17, the energy efficiency is high.
