The mist may be sprayed toward the roll brush 202 through the spray port 2012, and may also be sprayed toward the area to be cleaned.

The structural design of the liquid mixer 300 of the present embodiment can reduce the structural interference in installation in the cleaning apparatus 1, and facilitate the unified and centralized arrangement of the structures, such as the centralized arrangement of the liquid supply assembly 200, thereby improving the compactness of the structure, and can effectively and sufficiently mix the liquid, thereby improving the mixing effect. Reference may be made to the liquid mixer 300 as described below for embodiments of the liquid mixer of the present application.

Fig. 7 is a schematic view of the internal structure of an embodiment of the liquid mixer of the present application.

As shown in fig. 7, liquid mixer 300 may include an inlet pipe 302, an outlet pipe 330, and a mixing body 340. The inlet pipe 302 and the outlet pipe 330 are connected to the same side of the mixing body 340.

The liquid mixer 300 is provided with a liquid inlet 301, a liquid outlet 331 and a mixing channel 341. The mixing channel 341 is located between the liquid inlet 301 and the liquid outlet 331, and communicates the liquid inlet 301 and the liquid outlet 331. The mixing channel 341 is configured to mix the liquid flowing through the liquid inlet 301 and output the mixed liquid from the liquid outlet 331. The liquid inlet 301 and the liquid outlet 331 open on the same side of the liquid mixer 300. Specifically, the liquid inlet 301 is correspondingly arranged on the liquid inlet pipe 302. The liquid outlet 331 is opened in the liquid outlet pipe 330. The inlet pipe 302 and the outlet pipe 330 are fixedly connected to the same side of the mixing body 340. The mixing channel 341 opens into the mixing body 340.

By arranging the liquid inlet 301 and the liquid outlet 331 on the same side of the liquid mixer 300, the liquid inlet direction of the liquid inlet 301 and the liquid outlet direction of the liquid outlet 331 are both on the same side, the length of the liquid mixer 300 can be reduced, the compactness of the structure is improved, and the structural design is optimized. Moreover, due to the structural design, the occupied space of the liquid mixer 300 can be reduced during installation, the liquid mixer 300 is convenient to be matched with a liquid supply mechanism to be placed, and related mechanisms for liquid inlet and liquid outlet can be uniformly and intensively arranged, so that the structure compactness can be improved, and the liquid mixer is more flexible. The number of loading ports 301 may be at least two, and may comprise a first loading port 311 and a second loading port 321 which are arranged at intervals. Optionally, the first inlet 311 may be used for fresh water inflow. The second liquid inlet port 321 may be for inflow of a detergent. The liquid outlet 331 can be used for discharging the cleaning liquid obtained by mixing the clean water and the cleaning agent.

Specifically, the liquid inlet pipe 302 may include a first liquid inlet pipe 310 and a second liquid inlet pipe 320. The first liquid inlet 311 and the second liquid inlet 321 are correspondingly arranged at one end of the first liquid inlet pipe 310 and one end of the second liquid inlet pipe 320.

The first liquid inlet 311, the second liquid inlet 321, and the liquid outlet 331 are disposed on the same side of the liquid mixer 300, and the liquid inlet direction of the liquid from the first liquid inlet 311 and the second liquid inlet 321 is opposite to the liquid outlet direction of the liquid outlet 331. Specifically, the other ends of the first liquid inlet pipe 310, the second liquid inlet pipe 320 and the liquid outlet pipe 330 are fixedly connected to the same side of the mixing body 340. The first liquid inlet pipe 310, the second liquid inlet pipe 320 and the liquid outlet pipe 330 are arranged in parallel and at intervals. For example, clean water and detergent enter the mixing body 340 from one end of the first and second liquid inlet pipes 310 and 320, respectively, to be mixed, and the mixed liquid flows out from the liquid outlet pipe 330.

The dimensions of the first inlet 311 and the second inlet 321 are selected in relation to the flow rate of the liquid to be fed in. For example, the flow rate of fresh water is larger, the flow rate of cleaning agent is smaller, the flow rate of fresh water is larger and needs to flow in through the first inlet 311 with larger size, and the flow rate of cleaning agent is smaller and can flow in through the second inlet 321 with smaller size. Therefore, the size of the first liquid inlet 311 is larger than that of the second liquid inlet 321, so that the inflow amount of the detergent can be effectively controlled, and the smaller second liquid inlet 321 enables the detergent in the detergent inlet to flow more uniformly and achieve a more appropriate flow rate. Alternatively, the size of the loading port 301 may be a diameter, an area, or the like.

Optionally, the fluid mixer 300 is opened with an inlet chamber 346 and an outlet chamber 348. The liquid inlet cavity 346 is correspondingly communicated with the liquid inlet 301. The liquid outlet 331 is connected to the liquid outlet chamber 348. The inlet chamber 346 and the outlet chamber 348 are respectively communicated with the mixing channel 341. For example, the fresh water and the detergent flow into the first and second inlet ports 311 and 321, respectively, and flow into the mixing channel 341 after flowing through the inlet chamber 346. The mixed cleaning liquid flows out from the mixing passage 341, flows through the liquid outlet chamber 348, and flows out from the liquid outlet 331. Optionally, the cross-sectional area of the inlet port 301 in a plane perpendicular to the direction of liquid flow therein is less than the cross-sectional area of the inlet chamber 346 in a plane perpendicular to the direction of liquid flow. Likewise, the cross-sectional area of the liquid outlet 331 in a plane perpendicular to the flow direction of the liquid therein is smaller than the cross-sectional area of the liquid outlet chamber 348 in a plane perpendicular to the flow direction of the liquid.

By providing the inlet chamber 346 between the inlet port 301 and the mixing channel 341, the fast liquid flow flowing in from the inlet port 301 can be buffered, and similarly by providing the outlet chamber 348 between the mixing channel 341 and the outlet port 331, the fast liquid flow flowing out from the mixing channel 341 can be buffered, thus effectively reducing the speed of the inflowing liquid flow and the outflow liquid flow. And then the speed of slowing down influent stream can make influent liquid can carry out abundant mixing in mixing passageway 341, promotes the effect of mixing.

Optionally, the liquid inlet chamber 346 is provided with a first buffer 347 at both the inlet communicating with the liquid inlet 301 and the outlet communicating with the mixing channel 341 for buffering liquid flowing into and out of the liquid inlet chamber 346. The first buffer 347 is provided so that the liquid may transition between flowing from the inlet port 301 to the inlet chamber 346 and flowing from the inlet chamber 346 to the mixing channel 341, smoothing the flow rate of the liquid. Similarly, the liquid outlet cavity 348 is provided with a second buffering portion 349 at the inlet of the communicating mixing channel 341 and the outlet of the communicating liquid outlet 331 for buffering the liquid flowing into and flowing out of the liquid outlet cavity 348. The arrangement of the second buffering portion 349 enables the mixed liquid to play a transition role when flowing out to the liquid outlet cavity 348 and flowing out of the liquid outlet cavity 348 to the liquid outlet 331 from the mixing channel 341, so that the mixed liquid flow is smooth, and the splashing of the liquid after flowing out is avoided, or other problems caused by overlarge hydraulic pressure are avoided.

Alternatively, the sectional area of the liquid inlet chamber 346 in the section perpendicular to the flow direction of the liquid therein is larger than the sectional area of the adjoining partial mixing channel 341 in the section perpendicular to the flow direction of the liquid therein. Specifically, the sectional area of the liquid-intake chamber 346 in the section perpendicular to the flow direction of the liquid inside the liquid-intake chamber 346 is larger than the sectional area of the part of the mixing channel 341 connected to the liquid-intake chamber 346 in the section of the liquid flowing direction inside the part of the mixing channel 341. Alternatively, the sectional area of the liquid inlet chamber 346 in the section perpendicular to the liquid flow direction at the outlet of the communication mixing channel 341 is gradually reduced with the liquid flow direction.

When the liquid flows into the liquid inlet cavity 346, the pressure is stabilized in the liquid inlet cavity 346, and then the liquid enters the mixing channel 341 from the adjacent part of the mixing channel 341, because the cross-sectional area of the communication part between the liquid inlet cavity 346 and the mixing channel 341 (namely the outlet of the liquid inlet cavity 346 communicated with the mixing channel 341 described above) is gradually reduced towards the mixing channel 341, the liquid flow entering the mixing channel 341 from the liquid inlet cavity 346 can effectively adapt to the change of the communicated cross-sectional area, and further, the liquid flow is more stable and ordered, so that the sufficient mixing can be performed in the mixing channel 341.

Similarly, the cross-sectional area of the liquid outlet cavity 348 at the inlet of the communicating mixing channel 341 on the cross section perpendicular to the liquid flowing direction gradually increases along with the liquid flowing direction, so that the mixed liquid is buffered and decelerated, and enters the liquid outlet cavity 348 more smoothly.

In particular, the inlet chamber 346 may include a first inlet chamber 3461 and a second inlet chamber 3462.

As shown in fig. 7, the mixing channel 341 may include a first inlet channel section 342, a second inlet channel section 343, and a mixing channel section 344. The first inlet channel section 342 is communicated with the first inlet 311, the second inlet channel section 343 is communicated with the second inlet 321, the first inlet channel section 342 and the second inlet channel section 343 meet and are communicated with the mixing channel section 344, and the mixing channel section 344 is communicated with the outlet 331.

Specifically, the first inlet passage section 342 communicates with the first inlet cavity 3461. The second inlet passage section 343 communicates with the second inlet chamber 3462.

Optionally, the second inlet passage section 343 has a greater extension than the first inlet passage section 342. The second inlet channel section 343 is provided with a longer extension length, so that the flow rate of liquid can be controlled on the one hand, and the backflushing backflow caused by the mixing of the liquid flowing out of the first inlet channel section 342 and the liquid flowing out of the second inlet channel section 343 at the intersection of the first inlet channel section 342, the second inlet channel section 343 and the mixing channel section 344 can be slowed down on the other hand. For example, the first liquid inlet 311 is used for feeding clean water, the second liquid inlet 321 is used for feeding detergent, and the second liquid inlet 343 has a longer extension length, so that on one hand, the flow rate of the detergent can be controlled, and on the other hand, the backflushing backflow caused by mixing of the clean water flowing out of the first liquid inlet 342 and the detergent flowing out of the second liquid inlet 343 at the junction of the first liquid inlet 342, the second liquid inlet 343 and the mixing channel 344 can be reduced, thereby reducing the influence on the detergent subsequently entering the second liquid inlet 343.

Optionally, in order to prolong the second inlet channel section 343 and save the space occupied by the second inlet channel section 343, the second inlet channel section 343 may be bent. The second inlet channel section 343 is bent at least once. Fig. 7 shows a second inlet channel section 343 which is provided with at least three bends, in particular with a meandering shape. The second liquid inlet channel section 343 is bent at least once, so that the backflushing backflow caused when the liquid is mixed can be effectively reduced. For example, the first liquid inlet 311 is filled with clean water, the second liquid inlet 321 is filled with a cleaning agent, and the second liquid inlet channel section 343 is arranged to be bent at least once, so that the backflushing backflow caused when the clean water and the cleaning agent are mixed at the intersection of the first liquid inlet channel section 342, the second liquid inlet channel section 343 and the mixing channel section 344 can be further effectively reduced, the influence of the backflow of the liquid to the second liquid inlet 321 and the like on the subsequent flowing-in cleaning agent can be effectively reduced, and the influence on the mixing effect can be reduced as much as possible.

Optionally, the mixing channel section 344 includes a main channel 3441 and at least one bypass channel 3442, each bypass channel 3442 having two ends spaced apart from the main channel 3441. Wherein, the liquid is branched from a position where one end of the bypass 3442 communicates with the main channel 3441 to flow into the bypass 3442 and the main channel 3441, respectively, and the liquid of the bypass 3442 can be re-merged into the main channel 3441 from the other end of the bypass 3442.

As shown in fig. 7, a dividing portion 345 is provided between the main passage 3441 and the bypass passage 3442, and the main passage 3441 and the bypass passage 3442 surround the outer circumference of the dividing portion 345. The diversion portion 345 may be considered as an "island" surrounded by the main passageway 3441 and the bypass passageway 3442. The diverging portion 345 may include a sharp corner 3451 and an arc-shaped portion 3452, the arc-shaped portion 3452 is connected to the sharp corner 3451 on the side away from the sharp opening, and the arc-shaped portion 3452 is rounded from the sharp corner 3451. Among them, the bypass 3442 includes a linear sub-passage 3443 and an arc sub-passage 3444. The linear sub-passageway 3443 is located on one side of the sharp corner portion 3451, the main passageway 3441 is located on the other side of the sharp corner portion 3451, and the curved sub-passageway 3444 communicates the linear sub-passageway 3443 and the main passageway 3441 around the curved portion 3452.

The working principle of the mixing channel 341 is: the liquid, such as fresh water, flowing in through the first inlet channel section 342 and the liquid, such as detergent, flowing in through the second inlet channel section 343 are mixed for the first time at the intersection of the first inlet channel section 342, the second inlet channel section 343 and the mixing channel section 344. The liquid after the first mixing is divided for the first time, the mixed liquid flows from the dividing portion 345 into the bypass 3442 and the main channel 3441 respectively by using the sharp corner portion 3451 as a dividing point, the mixed liquid flowing into the bypass 3442 flows through the linear sub-channel 3443 first and then flows out from the arc sub-channel 3444, and a turbulent flow is formed due to reverse blockage at the intersection of the arc sub-channel 3444 and the main channel 3441, so that the mixed liquid flowing out of the bypass 3442 can be merged into the main channel 3441 again and mixed for the second time.

Optionally, at least two bypass channels 3442 are included in the mixing channel section 344, the at least two bypass channels being arranged at intervals in sequence along the extension direction of the main channel 3441 along 3442. Correspondingly, at least two flow dividing portions 345 are correspondingly enclosed between the at least two bypass passages 3442 and the main passage 3441.

By providing at least two bypass passages 3442, the mixed liquid obtained after the second mixing can continue to flow through the main passage 3441 and be branched again from the second branch portion 345 using the second sharp corner portion 3451 as a branch point. Similarly, there is also a reverse blockage at the intersection of the second arc-shaped sub-passageway 3444 and the main passageway 3441 to create turbulence, so that the mixed liquid flowing out of the second bypass passageway 3442 can join the main passageway 3441 again and be mixed again.

As shown in fig. 8, the liquid mixer 300 may include a detection sensor 350, and the detection sensor 350 may be a photoelectric sensor, an infrared sensor, or the like. The detection sensor 350 is used to detect whether there is liquid in a passage between one of the inlet ports 301 and the mixing channel 341. For example, the detection sensor 350 may be disposed at an outer side of the mixing body 340. The detection sensor 350 is used for detecting whether liquid exists in a passage between the first liquid inlet 311 and the mixing channel 341 or a passage between the second liquid inlet 321 and the mixing channel 341. Optionally, the number of the detection sensors 350 is at least two, and each detection sensor 350 is used for detecting whether there is liquid in the passage between each liquid inlet 301 and the mixing channel 341. For example, one detection sensor 350 is used to detect whether there is liquid in the passage between the first loading port 311 and the mixing channel 341, and the other detection sensor 350 is used to detect whether there is liquid in the passage between the second loading port 321 and the mixing channel 341.
