[0019] As can be seen from the above description of the present invention, compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the first technical solution, since the cleaning device includes a cleaning assembly, a sleeve and a water passing member, the cleaning assembly includes a first body, an opening and closing unit and an inner tube. The first body is provided with a first water passing cavity, a first channel and a second channel. The first channel communicates with the first water passing cavity, and the inner tube communicates with the second channel; the sleeve includes a first tube fixedly connected to the first body and communicating with the first water passing cavity and a second tube placed inside the first tube and communicating with the inner tube; the water passing member is provided with a third channel communicating with the first liquid supply device and the first tube and a fourth channel communicating with the second liquid supply device and the second tube; thus, independent first and second channels are realized, and the outlet of two different liquids is realized without mutual contamination. And because the sleeve is provided and connected to the first body, the volume of the overall device is reduced, which is convenient for taking.

[0021] 2. Second technical solution: The first body includes a foaming member and a housing, and the second liquid supply device stores a liquid for foaming; the housing is provided with a receiving groove for receiving the foaming member, and the foam outlet channel of the foaming member forms a second channel, and the cleaning device can form foam, thus facilitating cleaning.

[0022] 3. Third technical solution: The foaming member includes a foaming body, a diaphragm, a piston and a piston driving member. When the piston drives the central part of the diaphragm away from the first mixing surface, a negative pressure is formed, and the liquid and air enter the first mixing cavity between the diaphragm and the first mixing surface unidirectionally. The liquid entering is a liquid that is easy to foam. When the piston drives the central part of the diaphragm close to the first mixing surface, the foam is unidirectionally led out from the first mixing cavity. Since the piston moves reciprocally and continuously beats the liquid and air through the diaphragm, in this process, the liquid is broken and fined, making the mixing of the liquid and air more uniform and delicate, increasing the foaming effect, and during the extrusion process, the foam can also be unidirectionally led out of the first cavity for use. Through the above structure, foam can be effectively formed, and the foam is delicate and suitable for cleaning.

[0023] 4. Fourth technical solution: The foaming body further includes a filter screen and is provided with a second cavity and a second foam channel. The foam enters the second cavity from the first cavity through the first foam channel and is then led out through the second foam channel. Since the outlets of the first foam channel and the inlets of the second foam channel are both micropores, the foam is further made delicate. By setting a filter screen near the outlet of the second foam channel, the bubbles are further reduced, and multiple filter screens can be set as needed to gradually reduce the bubbles and increase the fineness of the bubbles.

[0024] 5. Fifth technical solution: The foaming member further includes a first one-way membrane and a second one-way membrane. The first one-way membrane is provided with a first blocking part, and the second one-way membrane is provided with a second blocking part; the first blocking part is driven by the piston to move away from or seal and fit to near the first mixing surface to make the liquid and air enter the first cavity unidirectionally, and the second one-way membrane is driven by the piston to move away from or seal and fit to the plane where the outlet of the first foam channel is located to make the foam unidirectionally led out from the first cavity, thereby realizing unidirectional communication. When the air inlet channel and the liquid inlet channel are configured to point to the first blocking part and the first foam channel is configured to point to the second blocking part, the high-speed water flow directly impacts the first blocking part, and the water becomes broken and fined after collision, making the mixing of the liquid and air more uniform and delicate, thus having a good foaming effect; the liquid directly impacts the second blocking part through the first foam channel, and foam is formed after collision to increase the foaming effect. Since the periphery of the diaphragm is fixed and the center is agitated, the setting of the first foam channel facing the central part of the diaphragm can more conveniently discharge the foam.

[0025] 6. Sixth technical solution: The opening and closing of the first channel is realized by the first opening and closing unit including a switching rod, a resetting member and a handle, which is simple to operate and convenient to use.

[0026] 7. The seventh technical solution is that the housing is also provided with a handle installation groove and a rotation support part; the handle includes a pressing part and a limiting part connected to each other, the limiting part is provided with a sliding groove and a rotation groove with a T-shaped cross section, and the rotation groove is used for the rotation support part to be inserted and form a rotation fit; the end of the switching rod away from the blocking part is inserted into the sliding groove and provided with a mounting part that slides with the sliding groove, and the mounting part is configured to be unable to detach from the sliding groove along the extension direction of the switching rod. This facilitates installation, and the transmission fit between the handle and the housing is convenient for force and easy to use.

[0027] 8. The eighth technical solution is to cooperate with the auxiliary pump through the liquid detection device to prevent the piston driving part of the foaming part from being difficult to complete the absorption of the liquid used for foaming due to the long sleeve, thereby ensuring normal foaming.

[0028] 9. The ninth technical solution includes a second opening and closing unit through the opening and closing unit, and the second opening and closing unit includes a foaming part switch, a control circuit board and the piston driving part. The foaming part switch is used to generate a foaming signal, and the control circuit board receives the foaming signal and starts the piston driving part to move the piston and drive the diaphragm to agitate, thereby generating bubbles.

[0029] 10. The tenth technical solution is that both the first tube and the second tube are hoses to make the cleaning component suitable for pulling and increasing the scope of use.

[0030] 11. The eleventh technical solution is that the inner tube includes a third hose and a first connecting piece, and one end of the first connecting piece is adapted to the third hose, and the other end thereof is adapted to the second tube, so that the second tube can use a universal tube to increase compatibility, reduce the length of the inner tube, and alleviate production and inventory pressures.

[0031] 12. The twelfth technical solution is a cleaning system, comprising a cleaning device, a first liquid supply device and a second liquid supply device; the first liquid supply device is used to provide water, and the second liquid supply device stores liquid for foaming, thereby realizing water cleaning and foaming cleaning, which is easy to use and clean.

[0032] 13. The thirteenth technical solution: When the first channel is opened, water sequentially passes through the first liquid supply device, the water passage, the third channel, the first pipe, the first water passage cavity, and exits from the first channel. When the second switch is opened, the water in the first liquid supply device enters the second water passage cavity through the water passage and enters the second mixing cavity from the fifth channel. Since the outlet of the fifth channel is a micropore, negative pressure will be generated at the outlet of the fifth channel, and the viscous cleaning agent in the second liquid supply device will be sucked into the second mixing cavity through the sixth channel, so that the water and the viscous cleaning agent are mixed in the second mixing cavity. The mixed liquid flows out of the second mixing cavity, and then sequentially enters the fourth channel of the water passing member, the second pipe, the inner pipe, and the foaming member for foaming. In this solution, the user only needs to store the viscous cleaning agent in the second liquid supply device, which is convenient to use, further avoids the problem of contamination of the viscous cleaning agent, and prolongs the service life of the viscous cleaning agent.

Refer to Figure 6 , the foaming member 2 includes a foaming body, a diaphragm 25, three first one-way membranes 26, one second one-way membrane 27, a piston 28, and a piston driving member. The foaming body includes a base 21, an intermediate body 22, a bubble outlet mechanism 23, and a piston housing 24.

[0078] Refer to Figure 7 , the base 21 includes a first main body 211, a liquid inlet pipe 212, and a first surrounding wall; the first main body 211 is provided with first grooves 2111, second grooves 2112, third grooves 2113, and fourth grooves 2114 that have openings and are adjacent to each other; the first grooves 2111, second grooves 2112, third grooves 2113, and fourth grooves 2114 are surrounded by the first surrounding wall and spaced apart to form; among them, the third groove 2113 is surrounded by the first groove 2111, the second groove 2112, and the fourth groove 2114, and is disposed at the central position of the first main body 211; the third groove 2113 and the fourth groove 2114 are connected through a first liquid passing port 2115; the end surface of the first main body 211 facing away from the first surrounding wall protrudes with a liquid inlet pipe 212.

In this embodiment, the number of the first air inlet holes 214 can be set to one. Since the density of the liquid is greater than that of the air, the more air is needed to achieve a better foaming effect. To facilitate the introduction of gas to increase bubbles, the first air inlet holes 214 can also be set in multiple numbers, but they should all communicate with the second groove 2112; the base 21 is further provided with a first mounting hole. The first mounting hole penetrates the first surrounding wall and the first main body 211 along the extending direction of the liquid inlet pipe 212. In this embodiment, the number of the first mounting holes is three and they are evenly arranged.

[0080] Refer to Figures 8 - 10, Intermediate 22 includes a second main body 221, a second surrounding wall, a mounting post 222, and a bubble outlet mechanism mounting portion 223.

At the second liquid passing port 2215, the second main body 221 protrudes towards the base 21 with a bubble outlet protrusion portion 2216 whose height is lower than that of the second surrounding wall. The bubble outlet protrusion portion 2216 is connected to the second surrounding wall, making the liquid level of the second liquid passing port 2215 smaller.

[0081] On the end face of the second main body 221 facing away from the base 21, there are three one-way film mounting grooves 2217. The end face of the second main body 221 facing away from the base 21 and the plane where the bottom of the one-way film mounting groove 2217 is located together form a first mixing surface 291. The three one-way film mounting grooves 2217 are respectively a liquid inlet one-way film mounting groove 22171 and two air inlet one-way film mounting grooves 22172. The second main body 221 is further provided with a second liquid passing hole 22181, two second air passing holes 22182, three first one-way film mounting holes 22183 and three third liquid passing holes 22184. The three first one-way film mounting holes 22183 are respectively a liquid inlet one-way film mounting hole 221831 and two air inlet one-way film mounting holes 221832. Among them, both ends of the second liquid passing hole 22181 and the liquid inlet one-way film mounting hole 221831 are respectively communicated with the fifth groove 2211 and the liquid inlet one-way film mounting groove 22171. The two second air passing holes 22182 and the two air inlet one-way film mounting holes 221832 are all communicated with the sixth groove 2212. One second air passing hole 22182 and one air inlet one-way film mounting hole 221832 are correspondingly connected to one air inlet one-way film mounting groove 22172 in a group. In this embodiment, there are two second air passing holes 22182 to facilitate increasing the air intake. The third liquid passing hole 22184 is communicated with the first mixing surface 291 and the seventh groove 2213. In this embodiment, there are three third liquid passing holes 22184, so that the foam can not only obtain a good gas-liquid mixing effect but also ensure a large flow rate. On the end face of the second main body 221 facing away from the base 21, three mounting posts 222 and a bubble outlet mechanism mounting part 223 are protrudingly provided. The intermediate body 22 is provided with three second mounting holes corresponding to the first mounting holes respectively. The second mounting holes penetrate through the second surrounding wall, the second main body 221 and the corresponding mounting posts 222. The intermediate body 22 is provided with a fourth liquid passing hole 2219. The fourth liquid passing hole 2219 penetrates through the bubble outlet mechanism mounting part 223 and the second main body 221 and is communicated with the eighth groove 2214.

[0082] Reference Figure 6, The bubble generating mechanism 23 is installed on the bubble generating mechanism installation part 223 to communicate with the fourth liquid passing hole 2219 to complete bubble generation. It includes a connecting seat 231, at least one filter screen 232 and a fixing seat 233. The fixing seat 233 is provided with a bubble outlet 2331. The fixing seat 233 is provided with a filter screen installation groove with an opening facing the connecting seat 231. This filter screen installation groove is used to install the filter screen 232. One end of the connecting seat 231 is hermetically fixed to the bubble generating mechanism installation part 223. The other end of the connecting seat 231 extends into the filter screen installation groove to be fixed to the fixing seat 233, and the filter screen 232 is clamped between the connecting seat 231 and the fixing seat 233, so that the filter screen 232 is arranged close to the bubble outlet 2331. Through the filter screen 232, the bubbles are further reduced, and multiple filter screens 232 can be provided as needed. For example, two ultra-fine filter screens 232 are designed. The first layer is above 300 meshes, the second layer is above 500 meshes, and they are separated by an intermediate layer in the middle to gradually reduce the bubbles and increase the fineness of the bubbles.

[0083] Reference Figure 11 , The piston housing 24 has an opening facing the intermediate body 22. Three diaphragm mounting openings 241 are formed on the shell wall at the open end of the piston housing 24. A piston driving member (not shown in the figure) and a piston 28 are installed in the piston housing 24. In this embodiment, it is a piston motor. The piston 28 has a crank connecting rod mechanism. Driven by the piston motor, the crank connecting rod mechanism drives the piston 28 to move back and forth. The end face of the piston housing 24 facing the intermediate body 22 is provided with a threaded blind hole adapted to the second mounting hole. The end face of the piston 28 facing the intermediate body 22 is provided with three mounting guide grooves 281 adapted to the agitating groove 253. The openings of the mounting guide grooves 281 are the same as those of the agitating groove 253. When the diaphragm 25 inserts the diaphragm mounting part 2512 into the diaphragm mounting opening 241 with the state that the agitating groove 253 faces away from the piston housing 24, the agitating groove 253 extends into the mounting guide groove 281.

[0084] Reference Figures 12 - 14 , The diaphragm 25 is made of an elastic material. The diaphragm 25 includes a third main body 251 and three agitating parts 252. The agitating parts 252 protrude from the end face of the third main body 251 facing the piston 28. A notch is provided on the side of the third main body 251 opposite to the agitating parts 252, and the notch extends to the agitating parts 252 so that the third main body 251 and the agitating parts 252 form an agitating groove 253. In this embodiment, there are three agitating grooves 253, including two air intake agitating grooves 2531 and one liquid intake agitating groove 2532. The volume of each air intake agitating groove 2531 is larger than that of the liquid intake agitating groove 2532, so that the air intake amount is more than the liquid intake amount, increasing the entry of gas and thus increasing the foaming effect. The third main body 251 is recessed from the periphery towards the center to form three relief parts 2511. Between two adjacent relief parts 2511, a diaphragm mounting part 2512 protruding circumferentially relative to the relief parts 2511 is formed. The diaphragm mounting part 2512 is adapted to be inserted into the diaphragm mounting opening 241.

[0085] Reference Figure 15 , the first one-way film 26 includes a first sealing portion 261 and a first one-way film mounting portion 262 that are integrally connected to each other. The first one-way film mounting portion 262 is used for movement guiding. In this embodiment, there are three first one-way films 26, corresponding to one second liquid passing hole 22181 and two second air passing holes 22182 respectively. Among them, the three first one-way film mounting portions 262 are adapted to be correspondingly inserted into the three first one-way film mounting holes 22183, and the three first sealing portions 261 are adapted to be placed in the corresponding three one-way film mounting grooves 2217. To facilitate the introduction of gas, the outer diameter of the first sealing portion 261 of the first one-way film 26 is smaller than the groove diameter of the intake one-way film mounting groove 22172.

[0086] Reference Figure 16 , the second one-way film 27 includes a second sealing portion 271 and three second one-way film mounting portions 272 that are integrally connected to each other. Each second one-way film mounting portion 272 is used for installation and movement guiding, and is adapted to be inserted into the third liquid passing hole 22184 with a clearance fit. The second sealing portion 271 is adapted to be placed in the corresponding seventh groove 2213.

[0087] Reference Figure 17 , Figure 18 , during installation, first install the second one-way film mounting portion 272 of the second one-way film 27 in the corresponding third liquid passing hole 22184. The clearance between the two forms a first foam channel. The inlet of the first foam channel is at the first mixing surface 291, and the outlet of the first foam channel forms micropores, making the foam more delicate when flowing out of the first foam channel; place the second sealing portion 271 of the second one-way film 27 in the seventh groove 2213; then install the first one-way film mounting portion 262 of the first one-way film 26 in the first one-way film mounting hole 22183, and place the first sealing portion 261 of the first one-way film 26 in the one-way film mounting groove 2217; then fixedly connect the piston motor in the piston housing 24, fixedly connect the linear output end of the piston motor to the piston 28, and place the piston 28 in the piston housing 24; then align the agitation groove 253 of the diaphragm 25 with the installation guiding groove 281 and insert the diaphragm mounting portion 2512 into the diaphragm mounting port 241 with the agitation groove 253 facing away from the piston housing 24; then correspondingly penetrate three screws through the first mounting holes on the base 21 and the second mounting holes on the intermediate body 22 and tightly screw them into the threaded blind holes on the piston housing 24; finally, hermetically and fixedly connect the connecting seat 231 of the foam discharging mechanism 23 to the foam discharging mechanism mounting portion 223 to complete the installation of the foaming member 2.

[0088] After the installation is completed, the seals of each mechanism are fitted, and the intermediate body 22 and the piston housing 24 enclose to form a first chamber 293. The first groove 2111 and the fifth groove 2211 enclose to form a liquid chamber, the second groove 2112 and the sixth groove 2212 enclose to form a gas chamber, the third groove 2113 and the seventh groove 2213 enclose to form a second chamber 294, and the fourth groove 2114 and the eighth groove 2214 enclose to form a third chamber 2951. The second chamber 294, the gas chamber, and the liquid chamber are separately isolated and not interconnected with each other. The gas chamber and the liquid chamber can store a certain amount of gas and liquid for convenient use. The second chamber 294 is communicated with the first chamber 293 through a first foam channel. The first liquid inlet hole 213, the liquid chamber, and the second liquid passing hole 22181 are sequentially communicated to form a liquid inlet channel; the first gas inlet hole 214, the gas chamber, and the second gas passing hole 22182 are sequentially communicated to form a gas inlet channel; the third chamber 2951, the fourth liquid passing hole 2219, and the foam outlet mechanism 23 are sequentially communicated to form a second foam channel. The outlet of the second foam channel is the foam outlet 2331. The filter screen 232 is arranged close to the outlet of the second foam channel; the narrow opening 296 formed by enclosing the second liquid passing port 2215 and the first liquid passing port 2115 is the inlet of the second foam channel, and this inlet is a micropore.

[0089] The first chamber 293 is provided with a first mixing surface 291. The gas inlet channel and the liquid inlet channel open at the first mixing surface 291; the periphery of the diaphragm 25 is fixedly connected to the chamber wall of the first chamber 293, dividing the first chamber 293 into a first mixing chamber 2931 and a pulsating chamber 2932. The piston 28 is installed in the pulsating chamber 2932 and reciprocates linearly relative to the body to drive the central part of the diaphragm 25 to move away from or close to the first mixing surface 291. The first mixing chamber 2931 is located between the diaphragm 25 and the first mixing surface 291. On the surface of the diaphragm 25 relative to the first mixing surface 291, a plurality of pulsating grooves 253 are concavely provided. Specifically, the pulsating grooves 253 are arranged corresponding to the outlets of the liquid inlet channel and the gas inlet channel. Through the pulsating grooves 253 arranged corresponding to the outlets of the liquid inlet channel and the gas inlet channel, the bottom wall of the pulsating groove 253 is driven by the piston 28 to move away from or close to the first mixing surface 291. Due to the larger deformation amount of the pulsating groove 253, a large negative pressure is formed, which is convenient for sucking in a large amount of air and liquid quickly. In this embodiment, at the gas inlet channel, the groove diameter size of the gas inlet pulsating groove 2531 is larger than the outer diameter size of the first blocking portion 261 of the first one-way membrane 26. When inhaling gas, the first blocking portion 261 can extend into the gas inlet pulsating groove 2531, increasing the interval between the end surface of the first blocking portion 261 facing the one-way membrane installation groove 2217 and the plane of the bottom of the one-way membrane installation groove 2217, facilitating the gas to enter the first chamber 293.

[0090] In this embodiment, the diaphragm 25 inserts the diaphragm mounting portion 2512 into the diaphragm mounting port 241 with the agitation groove 253 facing away from the piston housing 24, and its periphery is fixed to the cavity wall of the first cavity 293. It should be understood that it can also be peripherally fixed on the first mixing surface 291, for example, by pasting and fixing the periphery of the diaphragm 25 to the first mixing surface 291.

[0091] The specific operation of the first one-way membrane 26 is as follows: when the piston 28 moves away from the diaphragm 25, the first sealing portion 261 of the first one-way membrane 26 moves away from the first mixing surface 291, and liquid and gas enter unidirectionally from the liquid inlet channel and the gas inlet channel respectively; when the piston 28 moves towards the diaphragm 25, the first sealing portion 261 of the first one-way membrane 26 seals and fits the first mixing surface 291, and liquid and gas cannot flow out. The specific operation of the second one-way membrane 27 is that when the piston 28 moves away from the diaphragm 25, the second sealing portion 271 of the second one-way membrane 27 seals and fits the plane where the first foam channel outlet is located, and the foam cannot be led out from the first foam channel; when the piston 28 moves towards the diaphragm 25, the second sealing portion 271 of the second one-way membrane 27 moves away from the plane where the first foam channel outlet is located, and the foam enters the second cavity 294 unidirectionally through the first foam channel. When the bottom end of the second sealing portion 271 of the second one-way membrane 27 is higher than the thin opening 296, the second cavity 294 and the third cavity 2951 communicate, making the bubbles entering the third cavity 2951 finer, and finally leading them out from the bubble outlet mechanism 23.

[0092] Since the liquid inlet channel and the gas inlet channel are configured to point to the first sealing portion 261, the inlet direction of the gas and liquid is perpendicular to or at a certain angle with the first sealing portion 261 of the first one-way membrane 26, and the first foam channel is configured to point to the second sealing portion 271, and the liquid outlet direction of the foam from the first foam channel is perpendicular to or at a certain angle with the second sealing portion 271 of the second one-way membrane 27. The high-speed liquid directly impacts the first sealing portion 261, and the liquid becomes broken and finer after the impact, making the mixing of liquid and air more uniform and finer, so that the formed bubbles will be delicate. The liquid in the first foam channel directly impacts the second sealing portion 271 to form new bubbles, so that the foaming effect of the foam is good. Since the periphery of the diaphragm 25 is fixed and the center is agitated, the setting of the first foam channel facing the central part of the diaphragm 25 can more conveniently discharge the foam. In this embodiment, a bubble outlet protrusion 2216 is provided. When the bottom surface of the second sealing portion 271 rises to a height higher than the upper end surface of the bubble outlet protrusion 2216, the second cavity 294 and the third cavity 2951 communicate, which can increase the volume of the foam stored in the second cavity 294 and ensure that the diameter of the thin opening 296 is small enough.

[0093] As the piston 28 performs reciprocating motion, the diaphragm 25 is driven to agitate back and forth, continuously beating the liquid and the air. In this process, the liquid is broken up and finely divided, so that the liquid and air are mixed more evenly and delicately, thereby increasing the foaming effect. In this process, since the first one-way membrane 26 and the second one-way membrane 27 are provided, no backflow will be formed, and the liquid and air can enter the first chamber 293 unidirectionally, and the foam can be led out of the first chamber 293 to the second chamber 294 unidirectionally for use repeatedly. In the process of drawing out the foam, since the outlet of the first foam channel is a micropore, the large bubbles in the first cavity 293 are restricted from flowing out from the first foam channel, thereby making the bubbles flowing out from the first foam channel delicate, and since the first foam channel enters the second cavity 294 through a small hole into a large cavity, the foam in the first foam channel jets out at an accelerated speed and impacts the second blocking portion 271. The liquid that has not had time to form bubbles is broken and thinned after the collision, forming new foam; similarly, the second cavity 294 and the third cavity 2951 are connected through the narrow opening 296, that is, the inlet of the second foam channel is a micropore, and the large bubbles in the second cavity 294 are restricted from flowing out from the second foam channel, and the liquid in the second foam channel jets out and hits the cavity wall of the third cavity 2951. The liquid is broken and thinned after the collision to form new foam, and then passes through the filter 232, and bubbles are continuously formed and made delicate through multiple processes, thereby improving the foaming effect. Due to the provision of the first one-way membrane 26 and the second one-way membrane 27, when the membrane 25 is not agitated, that is, the piston motor is not working, the liquid cannot enter the first mixing chamber 2931 from the liquid inlet channel, and the second channel is in a closed state.

[0094] The opening and closing unit includes a first opening and closing unit and a second opening and closing unit;

[0095] The first opening and closing unit includes a switching rod 301, a reset member 302 and a lever-type handle 303 for controlling the opening and closing of the first channel 10; Figure 19 The switch rod 301 includes a blocking portion 3011, a rod portion 3012 and a mounting portion 3013 which are connected to each other as a whole and arranged in sequence along the first direction; the blocking portion 3011 is used to block or open the first water hole 31, thereby blocking or opening the water outlet channel, that is, closing and opening the first channel 10; one end of the switch rod 301 away from the blocking portion 3011 extends along the circumferential direction to form the mounting portion 3013; the reset member 302 is a spring, which is sleeved on the switch rod 301, and its two ends are respectively pressed against the blocking portion 3011 and the limiting wall 101 along the first direction, and the reset member 302 is suitable for driving the blocking portion 3011 to block the first water hole 31; refer to Figure 20 , Figure 21The handle 303 cooperates with the first body 10011 to rotate around a rotation axis. The handle 303 is movably connected to an end of the switching rod 301 away from the blocking portion 3011 on one side of the rotation axis. The handle 303 is suitable for being pressed and rotating around the rotation axis on the other side of the rotation axis to drive the switching rod 301 to move along the first direction and enable the blocking portion 3011 to open the first water hole 31, wherein the rotation axis is parallel to a second direction perpendicular to the first direction.

[0096] The handle 303 includes a pressing portion 3031 and a limiting portion 3032 which are connected to each other as one body; the limiting portion 3032 is provided with a sliding groove and a rotating groove 30322 with a T-shaped cross section, one end of the switching rod 301 away from the blocking portion 3011 is inserted into the sliding groove and the mounting portion 3013 is slidably matched with the sliding groove, and the mounting portion 3013 is configured to be unable to be separated from the sliding groove along the extension direction of the switching rod 301;

[0097] Specifically, the slide groove is formed by a slide hole 30321 and a limit groove 3033. The slide hole 30321 is connected to the limit groove 3033. The slide hole 30321 has an insertion opening facing downward, and the limit groove 3033 also has an insertion opening facing downward; the rotation groove 30322 is used for the rotation support part 18 to be inserted and form a rotation fit; the notch of the rotation groove 30322 is away from the pressing part 3031, and part of the rotation groove 30322 is penetrated by the slide hole 30321.

[0098] During installation, first insert the spring from one end of the installation part 3013 so that it sleeved on the rod part 3012 and abuts against the blocking part 3011. Then insert the switching rod 301 into the first groove 11 so that the rod part 3012 penetrates through the installation hole 19 of the switching rod 301 and the blocking part 3011 is placed in the first channel 10. To facilitate installation, appropriately apply force in the direction away from the notch of the first groove 11 to compress the spring and pull out the switching rod 301. Then align the sliding hole 30321 of the handle 303 with the rod part 3012 and the limiting groove 3033 with the installation part 3013, so that the rod part 3012 enters the sliding hole 30321 from the placement opening below the sliding hole 30321, and the installation part 3013 enters from the placement opening below the limiting groove 3033 and is placed in the limiting groove 3033. Let the spring loosen, and rotate the vertical rib of the supporting part 18 to extend into the sliding hole 30321 for positioning, and the horizontal rib cooperates with the groove wall of the rotating groove 30322 so that the handle 303 is rotationally matched with the first body 10011. When a force is applied to the pressing part 3031 of the handle 303, according to the lever principle, the blocking part 3011 moves along the first direction and towards the handle 303, the blocking part 3011 releases the first water passing hole 31, and the spring is compressed. When no force is applied to the pressing part 3031, the spring resets, so that the blocking part 3011 moves along the first direction and away from the handle 303, and the blocking part 3011 blocks the first water passing hole 31. This structure is convenient for installation, and the handle 303 is rotationally matched with the first body 10011, which is convenient for receiving force and convenient to use.

The signals received and sent can be directly transmitted electrical signals or indirectly transmitted wireless signals; the foam part switch 401 is a touch switch or an infrared sensor, or both are used together to control the start of the piston driving part through the control circuit board 402. There are two modes: when the touch switch is pressed gently, it is the induction mode. When the hand is placed towards the foaming port 2331, the infrared sensor senses it, and foaming occurs. When the hand is removed, the foaming stops; specifically, when the infrared sensor senses that the hand is at the foaming port 2331, it transmits the foaming signal to the control circuit board 402. The control circuit board 402 receives the foaming signal and sends a start signal to the piston motor. The piston motor receives the start signal and starts to drive the piston 28 to move, so that the foam part 2 foams. In another mode, when the touch switch is long-pressed for 5S, a foaming signal is formed and transmitted to the control circuit board 402. The control circuit board 402 controls the piston motor to start, and the piston motor drives the piston 28 to move, so that the foam part 2 foams directly. When it is necessary to close the foaming, just press the button again.

[0100] Reference Figure 5, The inner tube 10012 passes through the first water passage chamber 20 and communicates with the second passage to isolate the second passage from the first water passage chamber 20, and the liquids in the two do not affect each other; it includes a third flexible hose 100121 and a first connecting member 100122. The third flexible hose 100121 communicates with the second passage. Specifically, the third flexible hose 100121 is fixedly connected and communicated with the liquid inlet pipe 212 of the foaming member 2; the first connecting member 100122 includes a first plugging portion and a second plugging portion that communicate with each other. The first plugging portion is in sealing plugging fit with the third flexible hose 100121, and the second plugging portion is in sealing plugging fit with the second tube 10022; by one end of the first connecting member 100122 being adapted to the third flexible hose 100121 and the other end being adapted to the second tube 10022, the second tube 10022 can use a universal tube, so as to increase the compatibility, reduce the length of the inner tube 10012, and relieve the production and inventory pressure. Since it is convenient for installation, the third flexible hose 100121 will be slightly longer. After the installation is completed, it is bent and placed in the first water passage chamber 20. At the initial stage of pulling the first body 10011, the first tube 10021 deforms first, while the third flexible hose 100121 will straighten first and the second tube 10022 does not deform. Due to the setting of the first connecting member 100122, to prevent the first connecting member 100122 from abutting against the first tube 10021 and causing inability to stretch, the outer diameter of the first connecting member 100122 should be smaller than the minimum inner diameter of the outer flexible hose to be suitable for extending into the first tube 10021. However, the first connecting member 100122 extending into the first tube 10021 will hinder its water output. Therefore, the first connecting member 100122 is adapted not to abut against the first tube 10021 after the third flexible hose 100121 is stretched and straightened, so as to drive the second tube 10022 to stretch after the third flexible hose 100121 is stretched and straightened.

[0101] Reference Figure 5 , The sleeve 1002 includes a first tube 10021 fixedly connected and communicating with the first water passage chamber 20 of the first body 10011 and a second tube 10022 placed inside the first tube 10021 and communicating with the inner tube 10012. Specifically, one end of the first tube 10021 is threadedly connected and fixed to the external thread of the joint 8, and the third flexible hose 100121 and the second tube 10022 are communicated through the first connecting member 100122. In this embodiment, both the first tube 10021 and the second tube 10022 are flexible hoses so that the cleaning assembly 1001 is suitable for pulling, increasing the scope of use.

[0102] Reference Figures 22 - 24, the water passage member 1003 is provided with a third passage 10031 communicating with the first liquid supply device 200 and the first pipe 10021, and a fourth passage 10032 communicating with the second liquid supply device 300 and the second pipe 10022; the outlet of the fourth passage 10032 is disposed inside the outlet of the third passage 10031. The outer wall of the water passage member 1003 is provided with an external thread along the circumferential direction for screwing connection with the other end of the first pipe 10021, and the second pipe 10022 is adapted to be hermetically inserted into the fourth passage 10032.

[0103] The battery is electrically connected to the piston driving member, the alarm 1006, and the control circuit board 402 to provide energy; the liquid detection device 1004, which is electrically connected to the auxiliary pump 1005 and the control circuit board 402, is installed on the inner wall of the first connecting member 100122 and is used to detect whether there is liquid passing through;

[0104] The auxiliary pump 1005 and the controller, the inlet of the auxiliary pump 1005 communicates with the second liquid supply device 300, and the outlet of the auxiliary pump 1005 communicates with the fourth passage 10032; due to the relatively long sleeve 1002 or the too long pulling distance, it is difficult to complete the suction only by the piston driving member of the foaming member 2, and the auxiliary pump 1005 can help the foaming action to be normal. During use, when the liquid detection device 1004 detects that there is no liquid passing through, it emits a first signal, and the controller receives the first signal and starts the auxiliary pump 1005 to assist in the extraction of the liquid, so that the foaming member 2 can receive the liquid for foaming. The time detected by the liquid detection device 1004 can be after the foaming member switch 401 is turned on, or at any other time. The controller can exist independently or can be served by the control circuit board 402.

[0105] The alarm 1006, when the liquid detection device 1004 still fails to detect the liquid passing through after the auxiliary pump 1005 has been started for a period of time, emits a second signal, and after receiving the second signal, the control circuit board 402 controls the alarm 1006 to give an alarm to remind to supplement the liquid. The wireless charging module 400 is installed on the base body and is adapted to charge the battery when the first body 10011 is located on the wireless charging module 400.

[0106] When installing the cleaning system, install the wireless charging module 400 on the base; place the foaming member 2 in the receiving groove 13, and let its liquid inlet pipe 212 pass through the second hole 17 and extend into the second groove 12. Place the battery, the control circuit board 402, the foaming member switch 401, and the alarm 1006 in the panel groove 14. Since the panel groove 14 communicates with the receiving groove 13, the motor wire of the foaming member 2 located in the receiving groove 13 can pass through the communicating part to be electrically connected to the control circuit board 402 in the panel groove 14; the inner pipe 10012 extends into the second groove 12 from the first opening and is fixedly connected to the liquid inlet pipe 212, and the inner pipe 10012 is placed in the second groove 12; place the switching rod 301 and the spring in the first groove 11 and let the switching rod 301 pass through the switching rod mounting hole 19, screw the sealing seat 3 to the first groove 11, and make the blocking part 3011 of the switching rod 301 block the first water passing hole 31; finally, fixedly connect the front cover 4, the rear cover 5, the foaming cover 6, the water outlet cover 7, and the joint 8 to the housing 1 to complete the assembly of the cleaning assembly 1001. The fixing seat 233 of the foaming member 2 extends into the third hole 61 of the foaming cover 6. After installing the liquid detection device 1004 on the inner wall of the first connecting member 100122, connect and fix the second pipe 10022 to the first connecting member 100122, screw the first pipe 10021 to the joint 8, and then connect and fix the other ends of the first pipe 10021 and the second pipe 10022 to the water passing member 1003. Then connect the third channel 10031 of the water passing member 1003 to the first liquid supply device 200, and connect the fourth channel 10032 to the auxiliary pump 1005. Connect the auxiliary pump 1005 to the second liquid supply device 300 to complete the installation of the cleaning system. When in use, the user can pull the first body 10011 to extend the using distance, and use the foaming and water outlet functions to make the cleaning of items cleaner. This solution realizes the independent first channel 10 and second channel, realizes the water outlet of two different liquids without mutual contamination, and because the sleeve 1002 is provided and the sleeve 1002 is connected to the first body 10011, the volume of the overall device is reduced, which is convenient for taking, and the overall structure is simple and convenient for installation. Before use, the user can mix the foamable cleaning agent or viscous cleaning agent with water evenly and then put it into the second liquid supply device 300 for use.

[0107] Embodiment 2:

[0108] Reference Figure 25 , different from Embodiment 1, the cleaning system further includes a second connecting member 500 and a second switch 600; the second liquid supply device 300 stores a viscous cleaning agent, and the viscous cleaning agent needs to be mixed with water to achieve foaming; Reference Figure 26 、 Figure 27, the second connecting member 500 is provided with a second water passing cavity 5001, a fifth channel 5002, a second mixing cavity 5003, a sixth channel 5004 and a water passing channel 5005; the second water passing cavity 5001, the fifth channel 5002 and the second mixing cavity 5003 are connected in sequence, the outlet of the fifth channel 5002 is a micropore, the outlet of the second mixing cavity 5003 is connected to the fourth channel 10032 of the water passing member 1003, the sixth channel 5004 connects the second mixing cavity 5003 and the second liquid supply device 300, and the outlet of the sixth channel 5004 is a micropore; the water passing channel 5005 connects the third channel 10031 of the water passing member 1003 and the first liquid supply device 200, and the second switch 600 is installed on the second connecting member 500 and is used to control the connection between the second water passing cavity 5001 and the water passing channel 5005, so that water enters the second water passing cavity 5001, the fifth channel 5002 and the second mixing cavity 5003 in sequence from the water passing channel 5005, and the viscous cleaning agent enters the second mixing cavity 5003 through the sixth channel 5004 and mixes with water to form a liquid for foaming.

[0109] When the handle 303 of the first opening and closing unit is pressed, the first channel 10 is opened, and water flows out through the first liquid supply device 200, the water passing channel 5005, the third channel 10031, the first pipe 10021, the first water passing cavity 20, and the first channel 10 in sequence; the second switch 600 can be started simultaneously with the foaming member switch 401, and there is wireless communication between the two. When the foaming member switch 401 is opened, the second switch 600 is also opened. The water in the first liquid supply device 200 enters the second water passing cavity 5001 through the water passing channel 5005 and enters the second mixing cavity 5003 from the fifth channel 5002. Since the outlet of the fifth channel 5002 is a micropore, negative pressure will be generated at the outlet of the fifth channel 5002, and the viscous cleaning agent in the second liquid supply device 300 will be sucked into the second mixing cavity 5003 through the sixth channel 5004, so that water and the viscous cleaning agent are mixed in the second mixing cavity 5003. The mixed liquid flows out of the second mixing cavity 5003, enters from the inlet of the auxiliary pump 1005, and then enters the water passing member 1003, the second pipe 10022, the inner pipe 10012 and the foaming member 2 in sequence for foaming. A plurality of fifth channels 5002 can be provided to increase the water inflow, and the outlet of the sixth channel 5004 is a micropore to facilitate the adjustment of the ratio of the inflowing water and the inflowing viscous cleaning agent, ensuring that the mixed liquid is convenient for foaming. In this solution, the user only needs to store the viscous cleaning agent in the second liquid supply device 300, which is convenient to use, and further avoids the problem of viscous cleaning agent pollution and prolongs the service life of the viscous cleaning agent.
