The aforementioned FIG. 1 shows an exemplary structure of the cleaning device 1 . Another exemplary structure of the cleaning device 1 is shown in FIG. 4 . The structure of the cleaning device 1 shown in FIG. 4 is substantially the same as that of the cleaning device 1 shown in FIG. 1 , the main difference lies in the structure of the gripping portion 1021 . As mentioned above, the grip part 1021 can be an operating handle. For example, the first liquid may be clear water, and the second liquid may be a cleaning agent. Optionally, the discharge of cleaning fluid can be controlled and can be operated by an operating handle. The grip portion 1021 shown in FIG. 4 may be an operating handle, and the operating handle includes, for example, the handle assembly 100 .

The sliding operation part 122 is movably disposed on the switch body 121 between a first position and a second position along a first direction (as shown in FIG. 5 ). The knob 130 includes a rotation operation part 131 and a connection part 132 . The rotation operation part 131 is pivotally connected to the outside of the handle housing 110 about its own rotation axis. The connection part 132 may be fixedly connected to the rotation operation part 131 . In addition, the connecting portion 132 abuts against the sliding operation portion 122 along the first direction. For example, the connecting part 132 may be in contact with the two sides of the sliding operation part 122 along the first direction at the same time; In contact with the connecting portion 132 . The contact position between the connecting portion 132 and the sliding operation portion 122 deviates from the rotation axis, and the rotation axis is perpendicular to the first direction.

Wherein, the first direction is the direction in which the sliding operation part 122 can move relative to the handle housing 110 . Since the rotation axis of the knob 130 is perpendicular to the first direction, when the knob 130 is rotated, the connecting portion 132 will provide a tangential force to the sliding operation portion 122 to push the sliding operation portion 122 to move relative to the switch body 121, thereby realizing The slide operation part 122 moves between a first position and a second position.

By setting the slide switch 120 in the handle housing 110, the slide switch 120 has a switch body 121 and a slide operation part 122 that can move between the first position and the second position relative to the switch body 121 along the first direction, and then through A knob 130 is provided on the handle housing 110. The rotating operation part 131 of the knob 130 is located outside the handle housing 110 for manual operation. The connecting part 132 of the knob 130 extends into the handle housing 110 and abuts against the sliding operation along the first direction. part 122, and the joint between the connecting part 132 and the sliding operation part 122 deviates from the rotation axis of the knob 130, so that when the rotating operation part 131 is rotated, a force along the first direction can be applied to the sliding operation part 122 to drive the sliding operation part 122 moves along the first direction, thereby adjusting the operating state of the slide switch 120 . The present invention has a simple structure, and the sliding switch 120 is used instead of the rotary encoder, which can effectively reduce the cost.

Referring to FIG. 5 , FIG. 8 , FIG. 10 , FIG. 12 and FIG. 13 , for example, the connection portion 132 may be configured as a first abutment portion 132 a and a second abutment portion 132 b axially extending from the rotation operation portion 131 . The first abutting portion 132 a and the second abutting portion 132 b are arranged at intervals along the circumferential direction of the rotation operation portion 131 . The accommodating opening 132c formed between the first abutting portion 132a and the second abutting portion 132b is used to accommodate the slide operation portion 122 . When the rotating operation part 131 is rotated, the first abutting part 132 a or the second abutting part 132 b can apply an abutting force to the sliding operation part 122 , so that the sliding operation part 122 moves along the first direction. The abutting forces applied to the sliding operation portion 122 by the first abutting portion 132 a and the second abutting portion 132 b are opposite.

Referring to FIG. 5 , FIG. 12 and FIG. 13 , the handle housing 110 is provided with an installation hole 111 a, and the installation hole 111 a is used for installing the knob 130 . The knob 130 also includes a limit installation part 133 located between the rotation operation part 131 and the connection part 132 . The limiting installation portion 133 includes a tubular portion 133a and a locking protrusion 133b. The tubular portion 133a fits into the mounting hole 111a. The locking protrusion 133b is protrudingly provided on the outer peripheral surface of the tubular portion 133a in a radial direction. An end of the engaging protrusion 133b facing away from the rotation operation portion 131 has a guiding inclined surface 133b1. The guide slope 133b1 is inclined to the rotation axis, and the angle between the guide slope 133b1 and the rotation axis points to the rotation operation portion 131 . When the knob 130 is installed, the connecting portion 132 first extends into the installation hole 111a, and then the guide inclined surface 133b1 contacts and abuts against the inner wall of the installation hole 111a, and the locking protrusion 133b is under the action of the radial abutting force of the installation hole 111a Deform and close until the locking protrusion 133b crosses the mounting hole 111a and resets in the radial direction, so that the handle housing 110 at the mounting hole 111a is limited between the locking protrusion 133b and the rotating operation part 131 to achieve axial positioning; Since the tubular portion 133a fits into the mounting hole 111a, the radial position of the knob 130 in the mounting hole 111a is limited by the tubular portion 133a.

Referring to FIG. 5 , FIG. 12 and FIG. 13 , in order to enable adaptive deformation of the locking protrusions 133 b , escape grooves may be provided on the tubular portion 133 a between adjacent locking protrusions 133 b.

Referring to Fig. 5, Fig. 11 to Fig. 13, due to the cooperation of the knob 130 and the slide switch 120, it is possible to switch between two gears. During the rotation of the adjusting knob 130 , if it is not possible to perceive whether the knob 130 is rotated properly, it may affect user experience. For this, the outer peripheral surface of the tubular portion 133a is recessed radially inwards to form a first positioning recess 133a1 and a second positioning recess 133a2. The first positioning recesses 133a1 and the second positioning recesses 133a2 are arranged at intervals along the circumferential direction of the tubular portion 133a. The tubular portion 133a between the first positioning concave portion 133a1 and the second positioning concave portion 133a2 forms a spacing protrusion 133a3. The handle housing 110 has a positioning protrusion 111b protruding toward the tubular portion 133a along the radial direction of the installation hole 111a. The positioning protrusions 111b are adapted to the first positioning recesses 133a1 and the second positioning recesses 133a2 respectively, so that the positioning protrusions 111b passing over the spacing protrusions 133a3 can move into the first positioning recesses 133a1 or the second positioning recesses 133a2. By setting the first positioning concave portion 133a1 and the second positioning concave portion 133a2 on the tubular portion 133a of the knob 130, and setting the positioning protrusion 111b on the handle housing 110, the positioning protrusion 111b is respectively connected with the first positioning concave portion 133a1 and the second positioning concave portion 133a1. The positioning recesses 133a2 are respectively fitted. The positioning protrusion 111b and the spacer protrusion 133a3 hinder each other during rotation, and the positioning protrusion 111b will enter into the first positioning recess 133a1 or the second positioning recess 133a2 after passing over the spacer protrusion 133a3. During this process, through the cooperation of the positioning protrusion 111b and the spacing protrusion 133a3, the resistance during the rotation process is increased, and the resistance to be positioned is rapidly reduced when the positioning protrusion 111b passes over the spacing protrusion 133a3, allowing the user to feel the rotation Moreover, since the positioning protrusion 111b falls into the first positioning recess 133a1 and the second positioning recess 133a2, the position of the knob 130 can be well locked to prevent misoperation.

Referring to Fig. 5 to Fig. 8, Fig. 9, and Fig. 12 and Fig. 13, an indicating protrusion 131a may be formed extending radially outward on the outer peripheral surface of the rotating operation part 131, and the indicating protrusion 131a is used to indicate that the knob 130 is along the circumference The direction is relative to the position of the handle housing 110, and the user can quickly understand the status of the knob 130 through the indicating protrusion 131a. In addition, the indicating projection 131 a can also increase the frictional force and prevent slippage when the rotation operation part 131 is operated.

Referring to FIG. 5 to FIG. 8 and FIG. 9 , the exterior of the handle housing 110 has a first limiting portion 111c1 and a second limiting portion 111c2 arranged at intervals along the circumferential direction of the rotating operation portion 131 . The limiting gap formed between the first limiting portion 111c1 and the second limiting portion 111c2 is used to accommodate the indicating protrusion 131a to limit the rotation stroke of the indicating protrusion 131a, thereby helping to protect the knob 130 .

Referring to FIG. 5 to FIG. 8 and FIG. 9 , for example, the outer portion of the handle housing 110 is an arc-shaped limiting protrusion 144 extending outward along the rotation axis. The arc-shaped limiting protrusion 144 is concentric with the mounting hole 111a. Both circumferential ends of the arc-shaped limiting protrusion 144 are respectively configured as a first limiting portion 111c1 and a second limiting portion 111c2. The outer peripheral surface of the proximity indication projection 131 a of the rotation operation portion 131 is provided with a state indication portion. The status indicating portion is arranged corresponding to the arc-shaped limiting protrusion 144 . During the rotation of the knob 130 , the status indication part moves between a position covered by the arc-shaped limiting protrusion 144 and a position exposed in the limiting notch. For example, it can be agreed or set in advance that when the state indicating part is exposed in the limit gap and can be observed by the operator, it can be determined that the current state of the knob 130 is the open state.

Referring to Fig. 5 to Fig. 7, Fig. 9, and Fig. 11, during use, if the state indicating part is directly attached to the outer peripheral surface of the rotating operation part 131, the state indicating part may be affected by the arc-shaped limiting protrusion. Damaged by the friction of 144. In this regard, an accommodating groove 131b may be formed on the outer peripheral surface of the rotation operation part 131, and the state indicating part may be disposed in the accommodating groove 131b. The status indication part may be completely or partially located in the receiving groove 131b.

In some cases, the status indicator can be configured as a red label or a red paint layer, which can be more conspicuously drawn to attention. Of course, other easily recognizable colors can also be used.

The second housing portion 112 has an arcuate groove 112a adapted to receive the arcuate flange 111d. By dividing the handle housing 110 into a detachable first housing part 111 and a second housing part 112, and installing the slide switch 120 and the knob 130 on the first housing part 111, the flexibility of assembly can be increased And the operable space helps to improve assembly efficiency and facilitates later maintenance and replacement. By setting the arc-shaped flange 111d on the first housing part 111, and setting the arc-shaped groove 112a adapted to the arc-shaped flange 111d on the second housing part 112, it is convenient to align the first housing part 111 with the arc-shaped flange 111d. The relative position of the second housing part 112 is positioned, thereby improving the assembly efficiency and assembly quality.

Optionally, the spray port 2012 can also be arranged towards the outside of the opening of the accommodating space 2011, so that the cleaning liquid can be sprayed directly to the area to be cleaned.

Of course, the cleaning liquid can also be sprayed out in the form of steam, and the cleaning device 1 can also include a steam generator (not shown), which is used to evaporate the cleaning liquid output by the mixing device 300 into water vapor and then spray it out through the injection port 2012 . The water vapor can be sprayed to the roller brush 202 through the injection port 2012, and can also be sprayed to the area to be cleaned.

After long-term research by the inventors of the present application, it is found that the output flow of the cleaning device 1 may be different due to different usage scenarios and other conditions during use. For the working conditions with a small required flow rate, in addition to using a pump body with a small flow rate, you can also adjust the speed by adjusting the working frequency and voltage of the pump body to reduce the output flow of the liquid. However, the working frequency and working voltage cannot be reduced infinitely, which will cause the driving motor 203 to work outside the reasonable working range, cause extra heat, and even fail to start normally. If the required flow rate is much smaller than the rated flow rate of the smallest pump body on the market, it is difficult to solve the small flow problem. In addition, it is also possible to add a deceleration mechanism at the output end of the driver, so that the output speed is greatly reduced, so that the driver can still work in a reasonable speed range, but the driver must increase additional efficiency loss due to the newly introduced deceleration mechanism , and the deceleration mechanism needs to be equipped with a heat dissipation mechanism to offset the extra heat caused by the loss of efficiency.

For the above-mentioned problem of reducing the output flow rate of the liquid, the mixing device 300 of this embodiment can control the output flow rate of the first liquid. Regarding the content of the mixing device 300 of this embodiment, reference may be made to the following description of the mixing device embodiment of the present application.

As shown in FIG. 17 , the mixing device 300 may include a liquid flow regulating assembly 301 and a mixing tube 302 . The liquid flow adjustment assembly 301 can communicate with the mixing tube 302 . The liquid flow adjustment component 301 can input the liquid to be mixed to the mixing tube 302, and the liquid to be mixed can include the first liquid and the second liquid. The liquid flow adjustment component 301 can be used to adjust the output flow of the first liquid, and then can adjust the output ratio of the first liquid and the second liquid, so that different ratios of the first liquid and the second liquid can be input to the mixing tube 302 for mixing.

The liquid flow regulating assembly 301 may include a base 310 and a liquid separator wheel 320 . Optionally, the liquid flow regulating assembly 301 may further include a transmission mechanism 330 . Optionally, the liquid flow regulating assembly 301 may include an upper cover 340 and a lower cover 350 . The upper cover 340 can cover one side of the base 310 . The lower cover 350 can cover the opposite side of the base 310 . The upper cover 340 and the lower cover 350 can be used to protect the liquid separator wheel 320 and the transmission mechanism 330 .

As shown in FIG. 17 to FIG. 19 , the base 310 may be provided with an accommodating cavity 311 for accommodating the first liquid and a first output port 313 communicating with the accommodating cavity 311 .

Specifically, the first output port 313 is used to output the first liquid in the containing chamber 311 . The first liquid pump 210 can be connected to the accommodation chamber 311 so as to be able to inject the first liquid into the accommodation chamber 311 . Optionally, the base 310 may be provided with a first input port 312 , and the first input port 312 communicates with the accommodating cavity 311 for inputting the first liquid into the accommodating cavity 311 through the first input port 312 . Specifically, the first liquid pump 210 can be connected to the first input port 312 through a corresponding pipeline. Optionally, the accommodating cavity 311 and the first output port 313 are opened on one side of the base 310 . The first input port 312 is also disposed on one side of the base 310 . The upper cover 340 at least covers the accommodating chamber 311 to protect and position the liquid separator wheel 320 accommodated in the accommodating chamber 311 .

The liquid separation wheel 320 is rotatably accommodated in the containing cavity 311, and is used for dividing the first liquid in the containing cavity 311 into at least two liquids. Moreover, the liquid separation wheel 320 outputs at least two parts of the liquid respectively through the first output port 313 to the outside of the containing chamber 311 by the rotation.

Optionally, the outer circumference of the liquid separation wheel 320 has a plurality of liquid separation wheel teeth 321 distributed at intervals along the axial direction, and there are tooth grooves 322 between adjacent liquid separation wheel teeth 321 . Each alveolar 322 can be used to accommodate a part of liquid, so that the first liquid can be divided into multiple parts of liquid. The liquid separation wheel 320 can deliver each part of liquid to the first output port 313 in sequence by rotating. The distance between the tip of the liquid separation gear teeth 321 and the inner wall of the housing chamber 311 can be 0.03-1.5mm, optionally 0.05-1.3mm, optionally 0.08-1.2mm, optionally 0.1-1mm, optional 0.2-0.8mm, optional 0.3mm, 0.5mm or 0.6mm. By arranging the distance between the tip of the liquid separation gear 321 and the inner wall of the housing chamber 311 to be 0.05-1.5 mm, the width of the gap between the liquid separation gear 321 and the inner wall of the housing chamber 311 can be located at a reasonable position, The flow of the sub-liquid between the alveoli 322 is reduced, so that each part of the sub-liquid in the alveoli 322 is more uniform.

The transmission mechanism 330 is disposed on the base 310 and is in transmission connection with the liquid separator wheel 320 . The transmission mechanism 330 can be used to generate corresponding motion, such as rotation, to drive the liquid separator wheel 320 to rotate. The liquid separator wheel 320 is used to output at least two parts of the liquid respectively through the first output port 313 to the outside of the containing chamber 311 by rotation. For example, the liquid separation wheel 320 outputs a portion of the liquid to the outside of the containing chamber 311 every time the liquid separation wheel 320 rotates at a predetermined angle.

The first liquid is divided by the liquid separation wheel 320, and the liquid separation wheel 320 forces the sub-liquids to flow through rotation. When the sub-liquid flows to the first output port 313 , due to the pressure difference, it will flow out of the accommodating chamber 311 through the first output port 313 . During the rotation process, the liquid separation wheel 320 can sequentially output multiple liquids out of the housing chamber 311 through the first output port 313, divide the first liquid in the housing chamber 311 into multiple parts, and output each liquid to the housing chamber 311, and then can effectively reduce the single output flow of the first liquid, and use the hydraulic pressure brought by the rotation of the separator wheel 320 to make the sub-liquid output smoothly and reduce the backflow of the sub-liquid. Utilizing the liquid separation function and rotation of the liquid separation wheel 320, the control of small flow can be realized, and by adjusting the indexing relationship of the liquid separation wheel 320, the first liquid can be divided more finely, and the second liquid can be effectively adjusted. The flow rate per molecule of liquid for a single output of a liquid.

For example, the transmission mechanism 330 can generate intermittent motion, and can drive the liquid separator wheel 320 to rotate intermittently during the motion. The liquid separator wheel 320 is used to output at least two parts of the liquid to the outside of the containing chamber 311 through the first output port 313 by intermittent rotation. That is, driven by the transmission mechanism 330, the liquid separator wheel 320 can rotate intermittently, and each rotation can drive a part of the liquid to be output to the outside of the accommodation chamber 311 through the first output port 313, and then at least two parts of the liquid can be They are respectively output to the outside of the accommodating chamber 311 in portions through the first output port 313 . Optionally, the intermittent rotation of the liquid separation wheel 320 may cause a tooth groove 322 to be rotated to be opposite to the first output port 313 , so that the sub-liquid of the tooth groove 322 can be output through the first output port 313 .

The intermittent motion generated by the transmission mechanism 330 is used to drive the liquid separation wheel 320 to rotate intermittently. The liquid separation wheel 320 and the transmission mechanism 330 can form a set of indexing mechanism, which can divide the first liquid in the accommodation chamber 311 into multiple parts. The use of intermittent movement can orderly and clearly output each part of the liquid to the outside of the housing chamber 311, thereby effectively reducing the single output flow of the first liquid, and also reducing the mutual interference between each part of the liquid, thereby better Control the output flow of each sub-liquid. Moreover, by adjusting the transmission mechanism 330 and the liquid separation wheel 320, the flow rate of each part of the liquid in a single output of the first liquid can also be effectively adjusted, thereby realizing the control of a smaller flow rate. In addition, the flow control is realized by utilizing the transmission cooperation between the transmission mechanism 330 and the liquid separator wheel 320, and the structure is stable, safe and reliable.

The transmission mechanism 330 may be one of a sheave mechanism, a ratchet mechanism, an incomplete gear mechanism, a cam one-way intermittent movement mechanism, and an escapement mechanism. The above-mentioned mechanism can generate intermittent motion through motion, and utilize the intermittent motion to drive the liquid separator wheel 320 to rotate.

As shown in FIG. 17 , taking the transmission mechanism 330 as an example of a sheave mechanism, the transmission mechanism 330 may include a dial 331 and a sheave 332 . The dial 331 and the sheave 332 are respectively rotatably disposed on the base 310 . Optionally, the dial 331 and the sheave 332 are respectively rotatably disposed on the other side of the base 310 away from the accommodating cavity 311 . Optionally, a mounting groove 317 is provided on the other side of the base 310 away from the receiving chamber 311, the sheave 332 and the dial 331 are rotatably accommodated in the mounting groove 317, and the first transmission member 335 passes through the base 310 to Connect the sheave wheel 332 and the separator wheel 320 . The lower cover 350 can be provided on the other side of the base 310 away from the receiving cavity 311 to cover the installation groove 317 and further protect the transmission mechanism 330 and the like.

Specifically, as shown in FIGS. 17 and 18 , the dial 331 may be provided with a pin 333 . The pin 333 can be disposed on the edge of the dial 331 . When the dial 331 rotates in a circle, it can drive the dial 333 to rotate in the circumferential direction. The outer periphery of the sheave 332 is provided with at least two radial grooves 334 arranged at intervals. That is, the extending direction of the radial groove 334 is consistent or substantially consistent with the radial direction of the sheave 332 . The pin 333 is movably embedded in the radial groove 334 . During the circular rotation of the dial 331, the dial 333 drives the sheave 332 to rotate in a radial groove 334, and the sheave 332 stops after rotating to a certain extent, and the dial 333 continues to rotate into the adjacent dial 331. After another radial groove 334 of the grooved wheel, the grooved wheel 332 is driven to rotate, so that the grooved wheel 332 can realize intermittent rotation. In a word, the dial 331 can drive the sheave 332 to rotate intermittently through the dial pin 333 . The sheave 332 is connected in transmission with the liquid separation wheel 320, so as to drive the liquid separation wheel 320 to rotate intermittently.

By setting the sheave mechanism as the transmission mechanism 330, since the sheave 332 has an obvious indexing relationship, there can be a good corresponding relationship between the radial groove 334 and the tooth groove 322 of the separator wheel 320, which is convenient for structural matching design, and can It is convenient to set the number of radial grooves 334 and tooth grooves 322 according to the actual flow demand, thereby facilitating the flow control of the first liquid, and the structure of the sheave mechanism is stable, and the transmission connection between the sheave 332 and the separator wheel 320 can be transferred to The liquid separator wheel 320 outputs stable intermittent rotation, thereby effectively achieving the purpose of reducing the output flow of the first liquid.

Optionally, the sheave wheel 332 and the liquid separator wheel 320 are connected by transmission through a first transmission member 335 . The first transmission member 335 runs through two opposite sides of the base 310 , and then fixedly connects the sheave 332 and the liquid separator wheel 320 on the two opposite sides of the base 310 . Specifically, the first transmission member 335 may be arranged in a shaft shape, that is, the first transmission member 335 is a transmission shaft. The sheave wheel 332 and the separator wheel 320 are coaxially fixedly connected to the first transmission member 335 so that both can rotate synchronously. In this way, when the sheave wheel 332 rotates once, the separator wheel 320 rotates once.

Optionally, the number of the radial grooves 334 is the same as the number of the tooth grooves 322 of the separator wheel 320 , and the positions of the radial grooves 334 and the tooth grooves 322 can be in one-to-one correspondence. In this way, the first liquid in the storage cavity 314 can be effectively divided by using the corresponding relationship between the quantity and position of the two, and each part of the liquid can be sequentially output through the first output port 313 by using intermittent rotation. The tooth grooves 322 can be evenly opened on the outer periphery of the liquid separator wheel 320 , so that the first solution in the containing chamber 311 can be more evenly divided, and it is convenient to realize the supply of small flow rate or ultra-low flow rate.

For example, the number of tooth grooves 322 of the separator wheel 320 is 20, and the number of radial grooves 334 is also 20. When the dial pin 333 enters a radial groove 334 and exits from the radial groove 334, and drives the sheave 332 to rotate once, then the dial pin 333 withdraws from a radial groove 334 until it enters another adjacent radial groove 334, and the groove Wheel 332 will pause. When the groove wheel 332 rotates once, the liquid separator wheel 320 rotates once, and the position of the tooth groove 322 changes accordingly. In this embodiment, the separator wheel 320 and the groove wheel 332 of the corresponding tooth groove 322 can be selected according to the actual required output flow.

In an exemplary scenario, the first liquid pump 210 may work intermittently to cooperate with the work of the liquid separator wheel 320 and the transmission mechanism 330 capable of producing intermittent motion. For example, when the first liquid pump 210 is working, the first liquid is filled into the chamber 311 through the first input port 312, and the first liquid in the chamber 311 is divided into multiple parts by the separator wheel 320 and the transmission mechanism 330, and the Each part is transported out of the housing chamber 311 through the first output port 313, until all the first liquid in the housing chamber 311 is transported out of the housing chamber 311, the first liquid pump 210 starts working again to fill the housing chamber with the first liquid 311, that is, it can form a "empty-fill-empty" cycle, which can further facilitate the liquid separator wheel 320 to output each part of the liquid in a small flow mode, and reduce the excessive hydraulic pressure caused by the pump body to the housing chamber 311. lead to problems such as output failure.

In this embodiment, there are many ways to drive the dial 331 to rotate. For example, the dial 331 can be driven to rotate manually, a motor (not shown) can be provided to drive the dial 331 to rotate, or it can be driven by other methods. One of them is exemplified below.

As shown in FIG. 17 and FIG. 19 , the base 310 may define a receiving cavity 314 and a second input port 315 and a second output port 316 communicating with the receiving cavity 314 . The receiving chamber 314 and the receiving chamber 311 are arranged at intervals. Liquid flow adjustment assembly 301 may include drive wheel 360 . The driving wheel 360 is rotatably accommodated in the receiving chamber 314 . The driving wheel 360 is configured to be able to rotate under the push of the second liquid passing through the second input port 315 , the receiving cavity 314 and the second output port 316 . The driving wheel 360 is in transmission connection with the transmission mechanism 330 for driving the transmission mechanism 330 to move.

The receiving chamber 311 and the receiving chamber 314 may be disposed on one side of the base 310 at intervals. The driving wheel 360 is rotatably accommodated in the receiving cavity 314 . The second liquid pump 220 can be connected to the second input port 315 through a corresponding pipeline, and can pump the second liquid into the storage cavity 314 through the second input port 315 . The second liquid enters into the receiving cavity 314 through the second input port 315 and can generate thrust to the driving wheel 360 to drive the driving wheel 360 to rotate. After the driving wheel 360 rotates, the second liquid flows and then flows out from the second output port 316 . The driving wheel 360 can drive the transmission mechanism 330 to move. For example, the transmission mechanism 330 can generate intermittent motion during the movement, and the intermittent motion can drive the liquid separator wheel 320 to rotate intermittently. Certainly, the driving wheel 360 may also be driven by other means, such as by a motor.

By utilizing the push of the second liquid input into the receiving chamber 311 to drive the driving wheel 360 to rotate, and then to drive the transmission mechanism 330 to move, there is no need to introduce a new power source for driving, so that there is no need to introduce an additional noise source, which can not only effectively It saves energy and can effectively reduce noise.

Optionally, the second input port 315 communicates with the storage cavity 314 along the tangential direction of the storage cavity 314 , so as to input the second liquid through the inner wall of the storage cavity 314 along the tangential direction of the storage cavity 314 , and then push the driving gear teeth 362 . Furthermore, the second liquid pump 220 can continuously input the second liquid into the receiving cavity 314 through the second input port 315 , so that the driving wheel 360 can rotate uninterruptedly, thereby driving the transmission mechanism 330 to move continuously. For example, the transmission mechanism 330 can stably generate intermittent motion through continuous motion.

By arranging the second input port 315 to communicate with the storage cavity 314 along the tangential direction of the storage cavity 314, the second liquid can be input into the storage cavity 314 through the inner wall of the storage cavity 314 along the tangential direction of the storage cavity 314, so that the second liquid can preferentially hit To the outer end of the drive gear 362 away from the circular base 361, the thrust of the drive gear 362 is maximized, the power conversion efficiency is further improved, and the drive gear 362 can be driven to rotate more effectively, so that the drive wheel 360 can achieve stable turn.

Specifically, as shown in FIG. 17 , the driving wheel 360 and the dial 331 are connected in transmission. For example, the driving wheel 360 is connected to the dial 331 through the second transmission member 336 . The second transmission member 336 runs through two opposite sides of the base 310 , and then fixedly connects the dial 331 and the driving wheel 360 on the two opposite sides of the base 310 . Specifically, the second transmission member 336 may be arranged in a shaft shape, that is, the second transmission member 336 is also a transmission shaft. The dial 331 and the driving wheel 360 are coaxially fixedly connected to the second transmission member 336 so that the two can rotate synchronously. In this way, the driving wheel 360 synchronously drives the dial 331 to rotate during the rotation process, and the dial 331 drives the sheave 332 to rotate intermittently through the dial pin 333 , and then drives the separator wheel 320 to rotate intermittently.

Optionally, as shown in FIG. 20 , the drive wheel 360 may include a circular base 361 and drive gear teeth 362 connected to the edge of the circular base 361 at intervals. The extension direction of the drive gear 362 extending outward from the circular base 361 is the second The flow direction of the two liquids around the circular base 361 deviates from the radial direction of the circular base 361, for example, deviates from the radial direction of the circular base 361 passing through the root of the driving gear teeth 362, so that the second liquid can push the driving gear teeth 362 to make the driving gear 360 rotation.

The extension direction of the driving gear teeth 362 is deflected by a corresponding angle θ relative to the radial direction passing through its root, for example, 5-10°, 3-30°, 8-15° and so on. The direction of deflection is the flow direction of the second liquid around the circular base 361. For example, if the second liquid flows around the circular base 361 in a counterclockwise direction, the extension direction of the driving gear teeth 362 deviates from the corresponding counterclockwise direction. radial. The number of driving gear teeth 362 can be multiple, and the specific number can be designed according to the actual situation, which is not limited here.

By setting the extension direction of the gear to deviate from the corresponding radial direction in the flow direction of the second liquid, the second liquid can effectively generate thrust to the driving gear 362 after being injected into the receiving chamber 314, thereby smoothly pushing the driving gear 362 rotates to improve the effectiveness of the second liquid to push the driving gear teeth 362 and improve the power conversion efficiency.

The mixing device 300 can also achieve mixing of the first liquid and the second liquid. The above and mentioned first liquid is output with a small flow rate, while the second liquid is relatively output with a relatively large flow rate. In this way, the first liquid can be mixed in a larger proportion with a smaller proportion of the second liquid. For example, the first liquid is clear water, and the second liquid is a cleaning agent. Of course, the first liquid and the second liquid can also be other liquids.

As shown in FIG. 17 , the mixing tube 302 is disposed on the base 310 and can communicate with the first output port 313 and the second output port 316 to receive the first liquid and the second liquid. The mixing tube 302 can be used for mixing the first liquid output through the first output port 313 and the second liquid output through the second output port 316 . Specifically, the base 310 may be provided with a placement slot 318 and a liquid discharge port 319 , and the liquid discharge port 319 , the first output port 313 and the second output port 316 communicate with the placement slot 318 . The mixing tube 302 can be disposed in the placement tank 318 and can communicate with the first output port 313 , the second output port 316 and the liquid discharge port 319 , and the liquid discharge port 319 is used to discharge the liquid mixed by the mixing tube 302 .

It is worth mentioning that, in the cleaning device 1 , the liquid flow regulating assembly 301 is not necessary. That is to say, in one embodiment, the mixing device 300 may not include the liquid flow adjustment assembly 301, and the flow adjustment of the first liquid and the second liquid may not be performed, or the flow adjustment may be performed in other ways, for example, respectively setting and The regulating valves connected in series between the first liquid pump 210 and the second liquid pump 220 regulate the flows of the first liquid and the second liquid by controlling the regulating valves. In the cleaning device 1 , the mixing device 300 may also only need to realize the mixing function of the liquid, that is, realize the mixing of the liquid through the mixing tube 302 , for example, realize the mixing of the first liquid and the second liquid.

Regarding the content of the mixing tube 302 of this embodiment, reference may be made to the following description of an embodiment of the mixing tube of this application.

As shown in FIG. 21 , the mixing tube 302 may be provided with a mixing channel 371 . The mixing channel 371 can communicate with the first output port 313 and the second output port 316 for receiving the first liquid and the second liquid. The first liquid and the second liquid are input into the mixing channel 371 as liquids to be mixed for mixing. Optionally, the mixing tube 302 may also be provided with a liquid inlet chamber 372 and a liquid outlet chamber 373 . The mixing channel 371 can communicate between the liquid inlet chamber 372 and the liquid outlet chamber 373 . The liquid inlet chamber 372 is used to communicate with the first output port 313 and the second output port 316 . The liquid outlet cavity 373 is used to communicate with the liquid discharge port 319 .

Optionally, the mixing tube 302 may be provided with a liquid inlet 3701 and a liquid outlet 3702 . The number of liquid inlets 3701 can be multiple, for receiving the liquid to be mixed, and inputting the liquid to be mixed into the mixing channel 371. For example, the number of liquid inlets 3701 can be two, which are respectively used to receive the first liquid and the second liquid. The number of liquid outlets 3702 can be one or more, for outputting the liquid mixed through the mixing channel 371 . The liquid inlet 3701 and the liquid outlet 3702 are respectively connected to two ends of the mixing channel 371 , that is, the mixing channel 371 can be connected between the liquid inlet 3701 and the liquid outlet 3702 . Of course, the liquid inlet 3701 and the liquid outlet 3702 can be located at the same end of the mixing tube 302 , or can be located at both ends of the mixing tube 302 respectively. What is shown in FIG. 21 is the situation that the liquid inlet 3701 and the liquid outlet 3702 are respectively located at both ends of the mixing tube 302 , and the mixing channel 371 is opened between the two ends of the mixing tube 302 . Specifically, the liquid inlet 3701 is connected to the liquid inlet chamber 372 , and the liquid outlet 3702 is connected to the liquid outlet chamber 373 . Optionally, the mixing tube 302 can be provided with a liquid inlet pipe 303 and a liquid outlet pipe 304, the liquid inlet pipe 303 and the liquid outlet pipe 304 can be located at both ends of the mixing pipe 302, the liquid inlet pipe 303 is provided with a liquid inlet hole 3701, and the liquid outlet pipe 303 The liquid pipe 304 may be provided with a liquid outlet hole 3702 .

As shown in FIG. 22 , the liquid inlet chamber 372 can be arranged in a triangular shape, and the cross-sectional area of the liquid inlet chamber 372 gradually decreases along the path from the liquid inlet 3701 to the mixing channel 371 . The liquid outlet chamber 373 is arranged in a triangular shape, and on the path from the mixing channel 371 to the liquid outlet 3702 , the cross-sectional area of the liquid outlet chamber 373 gradually increases. By setting the liquid inlet chamber 372 with a larger space, more liquid to be mixed can be stored, so that the liquid to be mixed is initially mixed before entering the mixing channel 371, and the flow rate of the liquid to be mixed can be obtained in the liquid inlet chamber 372. A certain amount of buffering ensures that the liquid to be mixed can be mixed more fully when it enters the mixing channel 371 . At the same time, by arranging the liquid outlet chamber 373 with a larger space, the mixed liquid can be further mixed in the liquid outlet chamber 373 to further improve the mixing effect, and the liquid outlet chamber 373 can also play a temporary storage role, so that after mixing The liquid is temporarily stored in the liquid outlet chamber 373, and then flows to the cleaning assembly 20 as required.

In other examples, the mixing tube 302 may only be provided with one of the liquid inlet chamber 372 and the liquid outlet chamber 373 .

The mixing channel 371 in this embodiment can be set to strengthen the collision of the liquids to be mixed therein to achieve the effect of mixing and mixing.

In order to enable the mixing channel 371 to strengthen the collision between the liquids to be mixed, this implementation shows an exemplary structure of the mixing channel 371, as follows:

As shown in FIG. 22 , the mixing channel 371 may include a main channel 374 and at least one side channel 375 , and two ends of each side channel 375 communicate with the main channel 374 respectively.

That is, at least one bypass channel 375 is provided on the extension path of the main channel 374 , and the inlet and outlet of the bypass channel 375 communicate with the main channel 374 respectively. The liquid to be mixed enters the main channel 374, and part of the liquid can enter the bypass channel 375 during the flow process. The liquid in the main channel 374 can become a "main flow", and the liquid in the bypass channel 375 can become a "branch flow". Both ends of the 375 are connected to the main channel 374, so the main flow and the branch flow are bifurcated-converged to strengthen the collision of the liquid. The collision of the liquid can strengthen the mutual fusion of the first liquid and the second liquid, and then achieve the purpose of mixing, so that passive static mixing can be realized without active stirring, which is convenient and fast, and the mixing effect is remarkable.

Optionally, the number of side channels 375 may be 1-15, may be 3-10, may be 5-8, may be 7, or 9. Side channels 375 can be alternately arranged on both sides of the main channel 374 in a shifted position, thereby achieving a better mixing effect.

In order to further improve the mixing effect of the liquid to be mixed, the mixing channel 371 can be configured so that the liquid to be mixed can generate a vortex or a vortex-like effect therein. Specifically, a splitter portion 376 is correspondingly enclosed between the main channel 374 and each side channel 375 . The diversion part 376 can be arranged so that the liquid to be mixed flows from the diversion part 376 through the bypass channel 375 and the main channel 374 to generate a boundary layer effect. The splitter 376 is, for example, an island structure. Specifically, the mixed liquid flows through the bypass channel 375 and the main channel 374 from the splitter 376 respectively and can converge in the main channel 374 .

Boundary layer effect roughly refers to: the two-dimensional flow of viscous fluid around the airfoil at a large Reynolds number, the velocity of the fluid in the extremely narrow boundary layer increases sharply from zero on the wall to the same amount as the incoming flow velocity Therefore, the velocity gradient in the normal direction of the wall is very large, even if the dynamic viscosity coefficient of the fluid is small, the viscous force can still reach a large value, so the viscous force and inertial force in the boundary layer have the same Magnitude. Due to the large velocity gradient, there is considerable vortex strength in the fluid, so there is a swirl flow in the boundary layer. When the swirling flow in the boundary layer separates from the wall, a wake area with a significant velocity gradient is formed behind the object. Due to the influence of viscosity, the vortex in the wake gradually spreads, and the kinetic energy of the vortex gradually becomes heat energy and dissipates.

In short, due to the boundary layer effect, after entering the main channel 374, the liquid separated from the side channel 375 along the surface of the diversion part 376 will have a strong vortex collision with the liquid in the main channel 374, which is exactly the reason why the liquid is violently Where they collide and mix with each other. Since the diffusion phenomenon caused by eddy current hedging can occur in a small space, the space occupied by the mixing channel 371 can be greatly reduced, and the mixing effect can be well improved.

In order to further strengthen the mutual collision and collision of the liquids, the main channel 374 can be configured as a broken line, and the liquid in the main channel 374 can further collide due to the presence of the bends during the flow process, thereby further improving the mixing effect.

Specifically, as shown in FIG. 22 , the main channel 374 may be arranged in a zigzag shape, for example, including a plurality of sub-channels 3741 arranged in a straight line. Multiple segments of sub-channels 3741 are connected in sequence, and adjacent sub-channels 3741 are connected in a zigzag manner, so that the shape of the main channel 374 can be presented as a broken line. Optionally, the number of sub-channels 3741 may be 2-20, 5-15, 6-10, 7-9, or 8. Of course, the main channel 374 can also be arranged in a straight line. The zigzag connection between adjacent sub-channels 3741 means that the extension directions of adjacent sub-channels 3741 are set at an included angle, and the included angle can be set according to actual needs.

Optionally, every two adjacent sub-channels 3741 communicate with a bypass channel 375, and in the liquid flow direction of the main channel 374, the upstream sub-channel 3741 of each adjacent two sub-channels 3741 communicates with the corresponding bypass channel 375 , wherein the downstream sub-channel 3741 communicates with the outlet of the corresponding bypass channel 375 .

In other words, one bypass channel 375 can be connected to two adjacent sub-channels 3741 . In the liquid flow direction of the main channel 374 , one of the two adjacent sub-channels 3741 is located upstream and the other is located downstream. The upstream sub-channel 3741 communicates with the inlet of the corresponding bypass channel 375 , and the downstream sub-channel 3741 communicates with the corresponding outlet of the bypass channel 375 . The liquid to be mixed is branched at the upstream sub-channel 3741 , part of it enters the bypass channel 375 , and part of it flows into the downstream sub-channel 3741 . The liquid in the bypass channel 375 further flows into the downstream sub-channel 3741 to be mixed with the liquid in the downstream sub-channel 3741 . On the basis of the zigzag connection of the adjacent sub-channels 3741, the bypass channel 375 connects the adjacent sub-channels 3741 in a bridging manner, which can form a more complex channel structure, thereby strengthening the collision and hedging of the liquid during the flow process, and further Improves blending performance.

Furthermore, since two adjacent sub-channels 3741 are connected in a zigzag manner, the connection of two sub-channels 3741 arranged in a straight line will have a reciprocal angle and a minor angle. A corresponding bypass channel 375 may be provided at the reflex angle of every two adjacent sub-channels 3741 .

Optionally, at the position where the inlet of the bypass channel 375 communicates with the main channel 374, the included angle between the flow direction of the liquid at the inlet of the bypass channel 375 and the flow direction of the liquid in the main channel 374 is set at an acute angle, as shown in FIG. 23 out of the included angle α. Optionally, at the communication position between the outlet of the bypass channel 375 and the main channel 374, the flow direction of the liquid at the outlet of the bypass channel 375 and the flow direction of the liquid in the main channel 374 are set at an obtuse angle, such as the angle β shown in FIG. 23 .

As shown in FIG. 23 , the bypass channel 375 may be arranged in an arc shape. For example, the bypass channel may include a straight inlet section 3751 , a straight outlet section 3752 and an arc section 3753 . The arc section 3753 communicates with the inlet section 3751 and the outlet section 3752. In this embodiment, setting in a straight line may refer to setting in a substantially straight line, and a certain error is allowed, as long as the error does not affect the flow and mixing of the liquid. .

The inlet section 3751 communicates with the upstream sub-channel 3741 in a straight line. Specifically, the inlet section 3751 is in direct communication with the end of the upstream sub-channel 3741, so that the liquid in the upstream sub-channel 3741 can smoothly pass through the splitter 376 and enter the bypass channel 375, so as to better generate Boundary layer effect.

The outlet section 3752 communicates with the middle of the downstream sub-channel 3741 therein. That is, the liquid flowing out through the outlet section 3752 merges into the sub-channel 3741 in the middle of the downstream sub-channel 3741 . Here, the middle part is different from the end part, and any position between the two ends can be regarded as the middle part, and it is not limited to the most middle position.

Optionally, the component of the liquid flow direction of the outlet section 3752 in the extension direction of the downstream sub-channel 3741 is zero, that is, the liquid flow direction of the outlet section 3752 is perpendicular or substantially perpendicular to the extension direction of the sub-channel 3741, so that through the outlet Part of the liquid in the section 3752 collides with the liquid in the sub-channel 3741 in a vertically flowing direction, thereby maximizing the effect of mixing between the two. In addition, part of the liquid flowing out of the outlet section 3752 along the surface of the flow divider 376 due to the boundary layer effect can collide with the liquid in the sub-channel 3741 to generate a vortex effect. In this way, all the liquid flowing out through the outlet section 3752 can have a strong collision and hedging effect with the liquid in the sub-channel 3741, thereby improving the mixing effect.

Optionally, the component of the liquid flow direction of the outlet section 3752 in the extension direction of the downstream sub-channel 3741 is opposite to the liquid flow direction of the downstream sub-channel 3741 . That is, the liquid flow direction of the outlet section 3752 merges with the liquid of the corresponding sub-channel 3741 in an oblique inward manner. The component of the liquid flow direction in the outlet section 3752 in the extending direction of the corresponding sub-channel 3741 may become a horizontal component. The liquid flow direction of outlet section 3752 also has a vertical component perpendicular to the horizontal component. The horizontal component is opposite to the liquid flow direction of the corresponding sub-channel 3741 . By setting the component of the liquid flow direction of the outlet section 3752 in the extension direction of the subchannel 3741 located downstream and the liquid flow direction of the subchannel 3741 located downstream therein, the liquid flowing out of the outlet section 3752 and the liquid of the corresponding subchannel 3741 can be made The collision hedging is more direct and stronger, which can further enhance the vortex effect and make the mixing of the first liquid and the second liquid more uniform.

Optionally, the size of the outlet of bypass channel 375 is larger than the size of the inlet of bypass channel 375 . Such an arrangement enables the liquid in the bypass channel 375 to collide with the liquid in the opposing sub-channel 3741 in a wider range, thereby improving the mixing effect.

Optionally, outlet section 3752 gradually increases in size in the direction of liquid flow through outlet section 3752 . Such setting makes the liquid confluence area of the outlet section 3752 and the sub-channel 3741 larger, which is conducive to the formation of a vortex at the outlet of the outlet section 3752, and the liquid in the bypass channel 375 and the liquid in the sub-channel 3741 can be fully mixed in this area. Here, the size of the outlet and inlet of the bypass channel 375 and the size of the outlet section 3752 may be a cross-sectional area, for example, it refers to a cross-sectional area on a plane perpendicular to the flow direction of the liquid to be mixed.

In the mixing tube 302, by setting the mixing channel 371 to include a main channel 374 and at least one side channel 375, the two ends of each channel are respectively connected to the main channel 374, so that the main flow and the branch flow can be bifurcated and merged to strengthen the liquid collision. , thereby improving the mixing effect.

The mixing tube 302 described in the above embodiment of the mixing tube of the present application and another embodiment described below can be applied not only in the cleaning equipment 1 but also in other equipment requiring liquid mixing. The mixing tube 302 may also be called a liquid mixer in terms of naming.

The structural design of another embodiment of the mixing tube of the present application can reduce the structural interference installed in the cleaning device 1, facilitate the unified and centralized arrangement of the structure, such as the centralized arrangement of the liquid supply assembly 200, thereby improving the compactness of the structure, and can Effectively mixes the liquid thoroughly and improves the mixing effect. For the content of another embodiment of the mixing tube of the present application, please refer to the content of the above-mentioned one embodiment of the mixing tube of the present application, and the content of another embodiment of the mixing tube of the present application described below includes this embodiment and the above-mentioned one embodiment of the mixing tube of the present application For details, please refer to the following description.

As shown in FIG. 24 , the mixing pipe 302 may include a liquid inlet pipe 303 , a liquid outlet pipe 304 and a mixing body 305 . The liquid inlet pipe 303 and the liquid outlet pipe 304 are connected to the same side of the mixing body 305 .

As shown in FIG. 24 and FIG. 25 , the mixing tube 302 is provided with a liquid inlet 3701 , a liquid outlet 3702 and a mixing channel 371 . Wherein, the mixing channel 371 is located between the liquid inlet 3701 and the liquid outlet 3702 and communicates with the liquid inlet 3701 and the liquid outlet 3702 . The mixing channel 371 is used to mix the liquid flowing in through the liquid inlet 3701 , and output the mixed liquid through the liquid outlet 3702 . The liquid inlet 3701 and the liquid outlet 3702 are opened on the same side of the mixing tube 302 . Specifically, the liquid inlet 3701 is correspondingly opened in the liquid inlet pipe 303 . The liquid outlet 3702 is opened in the liquid outlet pipe 304 . The liquid inlet pipe 303 and the liquid outlet pipe 304 are fixedly connected to the same side of the mixing body 305 . The mixing channel 371 is opened in the mixing body 305 .

By opening the liquid inlet 3701 and the liquid outlet 3702 on the same side of the mixing tube 302, the liquid inlet direction of the liquid inlet 3701 and the liquid outlet direction of the liquid outlet 3702 are all on the same side, and the length of the mixing tube 302 can be reduced. Improve the compactness of the structure and optimize the structure design. Moreover, this kind of structural design can reduce the space occupation of the mixing tube 302 during installation, and facilitates the placement of the liquid supply mechanism in conjunction with the mixing tube 302, so that the relevant mechanisms for liquid inlet and liquid outlet can be uniformly and centrally arranged, and then The compactness of the structure can be improved, and the structure can be more flexible. The number of liquid inlets 3701 may be at least two, which may include a first liquid inlet 3703 and a second liquid inlet 3704 arranged at intervals. Optionally, the first liquid inlet 3703 can be used for clean water to flow in. The second liquid inlet 3704 can be used for the inflow of cleaning agent. The liquid outlet 3702 can be used for the cleaning liquid obtained after mixing the clean water and the cleaning agent to flow out.

Specifically, the liquid inlet pipe 303 may include a first liquid inlet pipe 306 and a second liquid inlet pipe 307 . The first liquid inlet 3703 and the second liquid inlet 3704 are respectively opened at one end of the first liquid inlet 306 and the second liquid inlet 307 .

Wherein, the first liquid inlet 3703, the second liquid inlet 3704, and the liquid outlet 3702 are opened on the same side of the mixing tube 302, and the liquid is fed from the first liquid inlet 3703, the second liquid inlet 3704 and the The liquid outlet direction of the liquid outlet 3702 is opposite. Specifically, the other ends of the first liquid inlet pipe 306 , the second liquid inlet pipe 307 and the liquid outlet pipe 304 are fixedly connected to the same side of the mixing body 305 . The first liquid inlet pipe 306 , the second liquid inlet pipe 307 and the liquid outlet pipe 304 are arranged in parallel and at intervals. For example, clean water and cleaning agent enter the mixing body 305 from one end of the first liquid inlet pipe 306 and one end of the second liquid inlet pipe 307 for mixing, and the mixed liquid flows out from the liquid outlet pipe 304 .

The size selection of the first liquid inlet 3703 and the second liquid inlet 3704 is related to the flow rate of the liquid to be inflowed. For example, the flow rate of clean water is relatively large, while the flow rate of cleaning agent is small. The clean water with large flow rate needs to flow in through the first liquid inlet 3703 with a large size, while the cleanser with a small flow rate can pass through the second liquid inlet port with a small size. 3704 inflow. Therefore, the size of the first liquid inlet 3703 is greater than the size of the second liquid inlet 3704, so that the inflow of cleaning agent can be effectively controlled, and the smaller second liquid inlet 3704 also makes the cleaning agent flow in it relatively Uniform and able to achieve a more suitable flow rate. Optionally, the size of the liquid inlet 3701 may be diameter, area, etc.

Optionally, the mixing tube 302 is provided with a liquid inlet chamber 372 and a liquid outlet chamber 373 . The liquid inlet chamber 372 communicates with the liquid inlet 3701 correspondingly. The liquid outlet 3702 communicates with the liquid outlet cavity 373 . The liquid inlet chamber 372 and the liquid outlet chamber 373 communicate with the mixing channel 371 respectively. For example, clean water and cleaning agent flow in from the first liquid inlet 3703 and the second liquid inlet 3704 respectively, flow through the liquid inlet chamber 372 and then flow into the mixing channel 371 . The cleaning liquid obtained by mixing flows out from the mixing channel 371 , flows through the liquid outlet cavity 373 and then flows out from the liquid outlet 3702 . Optionally, the cross-sectional area of the liquid inlet 3701 on a plane perpendicular to the flow direction of the liquid therein is smaller than the cross-sectional area of the liquid inlet chamber 372 on a plane perpendicular to the flow direction of the liquid. Likewise, the cross-sectional area of the liquid outlet 3702 on a plane perpendicular to the flow direction of the liquid therein is smaller than the cross-sectional area of the liquid outlet chamber 373 on a plane perpendicular to the flow direction of the liquid.

By setting the liquid inlet chamber 372 between the liquid inlet 3701 and the mixing channel 371, the fast liquid flow flowing in from the liquid inlet 3701 can be buffered. The cavity 373 can buffer the fast liquid flow flowing out from the mixing channel 371, so that the velocity of the incoming liquid flow and the outgoing liquid flow can be effectively reduced. Furthermore, slowing down the speed of the inflowing liquid flow can enable the inflowing liquid to be fully mixed in the mixing channel 371 and improve the mixing effect.

Optionally, the liquid inlet chamber 372 is provided with a first buffer portion 3711 at the inlet connected to the liquid inlet 3701 and the outlet connected to the mixing channel 371 for buffering the liquid flowing into and out of the liquid inlet chamber 372 . The setting of the first buffer portion 3711 enables the liquid to play a transitional role when the liquid flows into the liquid inlet chamber 372 from the liquid inlet 3701 and flows out from the liquid inlet chamber 372 to the mixing channel 371 , so that the flow rate of the liquid is smooth. Similarly, the liquid outlet chamber 373 is provided with a second buffer portion 3712 at the inlet of the mixing channel 371 and the outlet of the liquid outlet 3702 for buffering the liquid flowing into and out of the liquid outlet chamber 373 . The setting of the second buffer part 3712 makes the mixed liquid flow out from the mixing channel 371 to the liquid outlet chamber 373 and from the liquid outlet chamber 373 to the liquid outlet 3702, and plays a transitional role, so that the mixed liquid flow is gentle and avoids the liquid after the liquid is discharged. Splashing occurs, or excessive hydraulic pressure causes other problems.

Optionally, the sectional area of the liquid inlet chamber 372 on a section perpendicular to the flow direction of the liquid therein is greater than the sectional area of the adjacent part of the mixing channel 371 on a section perpendicular to the flow direction of the liquid therein. Specifically, the cross-sectional area of the liquid inlet chamber 372 on a section perpendicular to the liquid flow direction in the liquid inlet chamber 372 is greater than the cross section of the part of the mixing channel 371 connected to the liquid inlet chamber 372 in the liquid flow direction in the part of the mixing channel 371 the cross-sectional area above. Optionally, the cross-sectional area of the liquid inlet chamber 372 on the cross section perpendicular to the liquid flow direction at the outlet of the communication mixing channel 371 gradually becomes smaller along the liquid flow direction.

When the liquid flows into the liquid inlet chamber 372, it will first stabilize the pressure in the liquid inlet chamber 372, and then enter the mixing passage 371 from the adjacent part of the mixing passage 371, because the communication between the liquid inlet chamber 372 and the mixing passage 371 (also That is, the cross-sectional area of the above-described liquid inlet chamber 372 connected to the outlet of the mixing channel 371) gradually decreases toward the mixing channel 371, so that the liquid flow entering the mixing channel 371 from the liquid inlet chamber 372 can effectively adapt to the cross-sectional area of the flow. The change of the liquid flow makes the liquid flow more stable and orderly, which facilitates sufficient mixing in the mixing channel 371.

Similarly, the cross-sectional area of the liquid outlet cavity 373 at the entrance of the communication mixing channel 371 on the cross section perpendicular to the liquid flow direction gradually increases with the liquid flow direction, so that the mixed liquid is buffered and decelerated to make it more stable. into the outlet chamber 373.

Specifically, the liquid inlet chamber 372 may include a first liquid inlet chamber 3721 and a second liquid inlet chamber 3722 .

As shown in FIG. 25 , the mixing channel 371 may include a first liquid inlet channel segment 3713 , a second liquid inlet channel segment 3714 and a mixing channel segment 3715 . The first liquid inlet channel section 3713 is connected to the first liquid inlet port 3703, the second liquid inlet channel section 3714 is connected to the second liquid inlet port 3704, and the first liquid inlet channel section 3713 and the second liquid inlet channel section 3714 meet and communicate A mixing channel section 3715 , the mixing channel section 3715 communicates with the liquid outlet 3702 .

Specifically, the first liquid inlet channel section 3713 communicates with the first liquid inlet chamber 3721 . The second liquid inlet channel section 3714 communicates with the second liquid inlet chamber 3722 .

Optionally, the extension length of the second liquid inlet channel section 3714 is greater than the extension length of the first liquid inlet channel section 3713 . Setting the second liquid inlet channel section 3714 to have a longer extension length can control the flow of liquid on the one hand, and on the other hand can slow down the flow caused by the liquid flowing out of the first liquid inlet channel section 3713 and the liquid flowing out of the second liquid inlet channel section 3714. The recoil flow caused by the liquid mixing at the junction of the first liquid inlet channel section 3713 , the second liquid inlet channel section 3714 and the mixing channel section 3715 . For example, the first liquid inlet 3703 is used for the inflow of clean water, the second liquid inlet 3704 is used for the inflow of detergent, and the second liquid inlet channel section 3714 is set to have a longer extension length, on the one hand, the flow of detergent can be controlled , on the other hand can slow down by the clear water flowing out of the first liquid inlet channel section 3713 and the cleaning agent flowing out of the second liquid inlet channel section 3714 in the first liquid inlet channel section 3713, the second liquid inlet channel section 3714 and the mixing channel section The backflush and backflow caused by the mixing at the junction of 3715 can reduce the impact on the cleaning agent that subsequently enters the second liquid inlet channel section 3714 .

Optionally, in order to extend the second liquid inlet channel section 3714 and save the space occupied by the second liquid inlet channel section 3714, the second liquid inlet channel section 3714 may be bent. The second liquid inlet channel segment 3714 is bent at least once. The second liquid inlet channel section 3714 shown in FIG. 25 is bent at least three times, specifically in a meandering shape. By arranging the second liquid inlet channel section 3714 to be bent at least once, the recoil backflow caused by the mixing of liquids can be further effectively slowed down. For example, what the first liquid inlet 3703 flows into is clean water, and what the second liquid inlet 3704 flows into is cleaning agent. By setting the second liquid inlet channel section 3714 to be bent at least once, the flow of clean water and cleaning agent can be further effectively slowed down. The recoil backflow caused by the mixing at the intersection of the first liquid inlet channel section 3713, the second liquid inlet channel section 3714 and the mixing channel section 3715 can effectively reduce the liquid from flowing back to the second liquid inlet port 3704, etc. The impact of the inflowing cleaning agent is also minimized to minimize the impact on the mixing effect.

Optionally, the mixing channel section 3715 includes a main channel 374 and at least one side channel 375 , and two ends of each side channel 375 communicate with the main channel 374 at intervals. Wherein, the liquid diverges from the position where one end of the bypass channel 375 communicates with the main channel 374 to flow into the bypass channel 375 and the main channel 374 respectively, and the liquid in the bypass channel 375 can re-merge into the main channel 374 from the other end of the bypass channel 375 .

As shown in FIG. 25 , a splitter 376 is provided between the main channel 374 and the bypass channel 375 , and the main channel 374 and the bypass channel 375 surround the outer circumference of the splitter 376 . The splitter 376 can be regarded as an "island" surrounded by the main channel 374 and the side channel 375 . The splitter portion 376 may include a sharp corner portion 3761 and an arc portion 3762 , the arc portion 3762 is connected to the opening side of the sharp corner portion 3761 away from the sharp corner, and the arc portion 3762 and the sharp corner portion 3761 make a smooth transition. Wherein, the bypass channel 375 includes a straight sub-channel 3754 and an arc-shaped sub-channel 3755 . The straight sub-channel 3754 is located on one side of the sharp corner portion 3761 , the main channel 374 is located on the other side of the sharp corner portion 3761 , and the arc-shaped sub-channel 3755 connects the straight sub-channel 3754 and the main channel 374 around the arc-shaped portion 3762 .

The working principle of the mixing channel 371 is: the liquid flowing in through the first liquid inlet channel section 3713, such as clear water, and the liquid flowing in through the second liquid inlet channel section 3714, such as cleaning agent, are in the first liquid inlet channel section 3713, the second liquid inlet channel The first mixing occurs at the intersection of segment 3714 and mixing channel segment 3715. The liquid after the first mixing will be divided for the first time. The mixed liquid flows into the bypass channel 375 and the main channel 374 respectively from the diverging part 376 with the sharp corner part 3761 as the diverging point. The mixed liquid flowing into the bypass channel 375 first flows through the straight line. The sub-channel 3754 flows out after the arc-shaped sub-channel 3755, because there is a reverse blockage at the junction of the arc-shaped sub-channel 3755 and the main channel 374 to form turbulent flow, so that the mixed liquid flowing out of the bypass channel 375 can re-merge into the main channel 374 And a second mixing takes place.

Optionally, the mixing channel section 3715 includes at least two side channels 375 , and the at least two side channels 375 are sequentially arranged at intervals along the extending direction of the main channel 374 . Correspondingly, at least two flow splitters 376 are correspondingly surrounded by at least two bypass channels 375 and the main channel 374 .

By setting at least two bypass channels 375, the mixed liquid obtained after the second mixing will continue to flow through the main channel 374, and will be divided again from the second branch part 376 with the second sharp corner part 3761 as the branch point. . Similarly, at the junction of the second arc-shaped sub-channel 3755 and the main channel 374, there is also a reverse blockage to form turbulent flow, so that the mixed liquid flowing out of the second bypass channel 375 can re-merge into the main channel 374 and occur again. mix.

As shown in FIG. 24 , the mixing tube 302 may include a detection sensor 380, which may be a photoelectric sensor, an infrared sensor, or the like. Detection sensor 380 is used for detecting whether there is liquid in the path between a liquid inlet 3701 and the mixing channel 371. For example, the detection sensor 380 may be disposed outside the mixing body 305 . The detection sensor 380 is used to detect whether there is liquid in the passage between the first liquid inlet 3703 and the mixing channel 371 or the passage between the second liquid inlet 3704 and the mixing channel 371 . Optionally, there are at least two detection sensors 380 , and each detection sensor 380 is correspondingly used to detect whether there is liquid in the passage between each liquid inlet 3701 and the mixing channel 371 . For example, a detection sensor 380 is used to detect whether there is liquid in the passage between the first liquid inlet 3703 and the mixing channel 371, and another detection sensor 380 is used to detect whether there is liquid in the passage between the second liquid inlet 3704 and the mixing channel 371. Is there any liquid.

In the above embodiment, by opening the liquid inlet 3701 and the liquid outlet 3702 on the same side of the mixing tube 302, the length of the mixing tube 302 can be reduced, the compactness of the structure can be improved, and the structural design can be optimized. When installed in the cleaning equipment 1, the space occupied by the mixing tube 302 can be reduced, and it is convenient to match the mixing tube 302 with the position of the liquid supply mechanism, so that the relevant mechanisms for liquid inlet and outlet can be set and arranged in a unified and centralized manner, and then The compactness of the structure can be improved, and the structure can be more flexible.

The above is only an embodiment of the application, and does not limit the patent scope of the application. Any equivalent structure or equivalent process conversion made by using the specification and drawings of the application, or directly or indirectly used in other related technologies fields, are all included in the scope of patent protection of this application in the same way.
