Referring to Figures 12-15 and 8-11 at the same time, Figure 12 is a schematic structural diagram of the roller brush with half of the cylinder removed in one embodiment. Figure 13 is a partial cross-sectional view of a fluid distributor in one embodiment. Figure 14 is a schematic structural diagram showing the first channel in the flow guide element. Figure 15 is a schematic structural diagram showing the second channel in the flow guide element. The fluid distributor 4 and the heating device are described in detail according to the figure. The fluid distributor 4 includes an elongated body 42 and a flow guide element 43 disposed inside the elongated body 42. Referring to FIGS. 12 and 9 , the elongated body 42 includes a first end and a second end that are oppositely arranged along its length direction. A first fixing part 44 is provided at the first end, and the first fixing part 44 is detachably fixed to the first end cover 45 connected to the handle 6 . A second fixed part 46 is provided at the second end. Bearings are provided on the outer periphery of the first fixed part 44 and the second fixed part 46 . Both ends of the brush cylinder 7 are installed on the bearings so that the brush cylinder 7 Rotated relative to the fluid distributor 4. The second fixed part 46 is rotatably mounted to the second end cap 47 through bearings, and the second end cap 47 is used to install the brush cylinder. The first end cap 45 is fixedly connected to the fluid distributor, and the two remain relatively stationary. Referring to Figures 12-15, the slender body 42 is a long hollow cylinder, and the flow guide element 43 is provided inside the slender body 42. The flow guide element 43 is provided with a flow guide groove, and the flow guide groove cooperates with the slender body 42. A flow guide channel 48 is formed for guiding fluid to the liquid outlet 41 provided on the elongated body 42 . Furthermore, a ring of sealing strips 483 is provided around the outer periphery of the flow guide groove. The sealing strips 483 are respectively in contact with the flow guide element 43 and the elongated body 42 to prevent fluid from flowing out of the flow guide channel 48 . As shown in FIGS. 14 and 15 , the flow guide channel 48 includes a first channel 481 and a second channel 482 connected with the first channel 481 and located downstream of the first channel 481 . At least part of the first channel 481 extends along the length direction. The bending extension here can be a circuitous extension or a spiral extension. At least a portion of the second channel 482 extends along the length of the elongated body 42 . At least part of the second channel 482 corresponds to the liquid outlet 41 of the fluid distributor 4, and the fluid in the second channel 482 is discharged through the liquid outlet 41. Referring to Figure 13, the elongated body 42 is provided with at least one set of liquid outlets (Figure 13). The set of liquid outlets includes a plurality of liquid outlets 41, and the plurality of liquid outlets 41 are between the first end and the second end. interval distribution. The liquid outlet 41 is set up like this This arrangement can effectively ensure uniform liquid discharge along the length direction of the elongated body 42. In order to make the liquid output of each liquid outlet 41 relatively uniform, the inlet of the second channel 482 is generally set at an intermediate position corresponding to a group of liquid outlets.

Referring to Figures 8-12, a heating device is used to heat a fluid. In the embodiment shown in the figures, the heating device includes a heating element 51 disposed on the elongated body 42. In the embodiment shown in the figure, the heating device is used to heat the fluid before flowing out from the fluid distributor 4 , and then the heated fluid flows out from the fluid distributor 4 . Referring to FIG. 12 , the heating element 51 is disposed in a heating area defined by the elongated body 42 . As shown in the embodiment shown in the figures, the heating zone may occupy only a portion of the elongated body 42. In other embodiments, the heating area may also cover the entire elongated body 42 . The heating element 51 can be an electric heating piece, which is fixed to the heating area of the elongated body 42 by adhesion or other means. The heating element 51 can also be directly etched onto the elongated body 42, and the etching process will not be described in detail here. When the elongated body 42 includes an outer wall and an inner wall, the heating element 51 can be disposed on the outer wall or the inner wall of the elongated body 42, depending on the shape of the elongated body 42 and actual requirements. The elongated body 42 corresponding to the heating area is generally supported by a material with good thermal conductivity. Metal materials or other materials with good thermal conductivity can be used, which will not be described in detail here. The flow guide element 43 is generally made of materials with relatively good thermal insulation properties to prevent heat loss. The heating device can also be a steam generator for generating steam which is sprayed through the fluid outlet onto the wiped specimen and/or the surface to be cleaned.

In one embodiment, the heating area is arranged at the lower end of the elongated body 42 along the direction of gravity, and the flow guide element 43 is arranged above the heating area. In this way, during the operation of the heating device, the fluid in the flow guide channel 48 is caused by gravity. The effect will be close to the heating area. Even if the flow rate in the diversion channel 48 is insufficient, the liquid will fully contact the heating area to ensure the heating effect of the liquid. The elongated body 42 can be made of materials with good thermal conductivity, such as copper, aluminum, solid thermally conductive silicone, etc., which are not limited in detail here.

In other embodiments, the fluid distributor 4 can also be a separate conduit, a heating device is provided on the outer periphery or inside of the conduit, and a liquid outlet can be provided on the peripheral wall of the conduit. When the heating device is arranged on the outer periphery of the conduit to transfer heat through the conduit, the conduit can be made of materials with good thermal conductivity. When the heating device is installed inside the conduit, or when the heating device is far away from the fluid distributor 4, the conduit can be made of materials with better thermal insulation properties. material support.

Referring to Figures 8-11, since the fluid distributor 4 does not rotate with the roller brush, the fluid discharged by the fluid distributor 4 will enter the annular cavity and be discharged. In order to ensure that the liquid can be quickly discharged from the fluid outlet 71, a plurality of liquid collection chambers 74 corresponding to the liquid outlet 41 are provided in the accommodation space of the roller brush cylinder 7, and the plurality of liquid collection chambers 74 are arranged along the roller brush. arranged at intervals in the axial direction. The brush cylinder 7 is provided with at least one set of fluid outlets 71 . The liquid flowing out from the liquid outlet 41 is collected by the liquid collection chamber 74 and then discharged through the fluid outlet 71 . The liquid outlets 41 are arranged at intervals along the axial direction of the roller brush. The liquid ejected from each liquid outlet 41 is collected by the corresponding liquid collecting chamber 74 and then discharged through the fluid outlet 71, which can ensure that the cleaning liquid is along the axial direction of the roller brush. Discharge evenly, and at the same time, distributing the liquid collecting chambers 74 at intervals can effectively ensure that the fluid sprayed from the liquid outlet 41 is collected into the liquid collecting chamber 74 for the first time and then discharged, thereby preventing a large amount of cleaning liquid from accumulating in the internal volume of the roller brush. placed in the space. The liquid collecting chamber 74 may be defined by a flow blocking structure 75 protruding outward from the inner wall of the roller brush cylinder 7 . The flow blocking structure 75 may define an independent space that is sealed around it. The flow blocking structure 75 may also have a fluid inlet. The baffle structure prevents the fluid here from rotating relative to the brush cylinder 7 .

Referring to Figures 16-17, and also referring to Figure 11, in another embodiment, since the liquid collecting chamber 74 rotates together with the brush cylinder 7, the liquid sprayed from the liquid outlet 41 is likely to not be collected. Liquid chamber 74 collects. Therefore, the liquid collection chamber 74 is an annular groove extending along the circumferential direction of the roller brush. During the rotation of the roller brush, the annular groove corresponds to the liquid outlet 41 , that is, the fluid ejected from the liquid outlet 41 is extremely large. Part or even all of it is collected by the annular groove. Referring to FIG. 16 , at least one flow blocking structure 75 is provided in the annular groove. The flow blocking structure 75 is used to block at least part of the fluid from moving relative to the brush cylinder 7 so that at least part of the fluid collects near the fluid outlet 71 . Along the rotation direction of the roller brush, the flow blocking structure 75 is generally provided downstream of the fluid outlet 71. In this way, the flow blocking structure 75 can block at least part of the fluid so that the fluid rotates with the roller brush. This part of the fluid will be separated from the fluid due to the action of centrifugal force. Outlet 71 flows out. The flow blocking structure 75 may be a baffle extending along the axial direction of the roller brush. The baffle directly closes the annular groove so that the fluid cannot circulate freely along the annular groove. The flow blocking structure 75 can also be a block provided around the fluid outlet 71, and the block does not completely close the annular groove, but only blocks part of the fluid to remain near the fluid outlet 71, and the remaining fluid Can flow around the block. The advantage of this arrangement is that most of the fluid is prevented from gathering in the fluid outlet 71, and the fluid outlet 71 cannot completely remove it. The excess fluid will overflow into the accommodation space, causing energy loss. In other embodiments, along the rotation direction of the roller brush, a plurality of fluid outlets 71 may be respectively disposed on both sides of the flow blocking structure 75 .

Further, in order to ensure that most of the liquid discharged from the liquid outlet 41 is collected into the liquid collecting chamber 74 . The liquid collecting chamber 74 corresponds to the liquid outlet 41 of the fluid distributor 4 , so that the fluid sprayed from the liquid outlet 41 of the fluid distributor 4 directly falls into the liquid collecting chamber 74 . Specifically, the liquid outlet 41 of the fluid distributor 4 can also extend into the annular groove. Furthermore, in order to prevent the fluid outside the liquid collecting chamber 74 from being discharged smoothly, at least one fluid outlet 71 may be provided outside the liquid collecting chamber 74 .

Referring to Figure 9, in one embodiment, the brush cylinder 7 includes a first cylinder 72 and a second cylinder 73. Each part includes at least one semicircular groove. After manufacturing, it is fixed by bolts or other means. When fastened together they form a complete annular groove. In this embodiment, the annular groove is defined by two annular plates that protrude relative to the inner wall of the brush cylinder 7 . In other embodiments, the annular groove may also be formed by an inward depression of the inner wall of the brush cylinder 7 . Of course, other mature processes can also be used to form spaced grooves in a hollow brush cylinder 7 .

Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and embodiments. They can be applied to various fields suitable for the present invention. For those familiar with the art, they can easily Additional modifications may be made and the invention is therefore not limited to the specific details and illustrations shown and described herein without departing from the general concept defined by the claims and their equivalent scope.
