Description

Technical Field

[0001] This invention relates to the field of cleaning machine technology, and in particular to a cleaning machine that is easy to control. Background Technology

[0002] A cleaning machine is a cleaning device that helps people complete cleaning tasks. In daily life, a cleaning machine can be used to clean dirty floors. The working principle of a cleaning machine is to use a water pump to spray clean water from a water tank to clean the dirty floor. To improve the cleaning effect, detergent needs to be added to the clean water during the cleaning process to enhance the cleaning effect on the dirty floor.

[0003] In most existing technologies, detergent is directly added to the water tank, and the dirty floor is cleaned after the detergent mixes with the water. However, after cleaning with the mixed solution, it is often necessary to rinse with clean water again to remove the detergent residue. At this time, the liquid in the water tank needs to be replaced with clean water, which makes the overall cleaning work complicated and reduces the efficiency of the cleaning work. Summary of the Invention

[0004] This application provides a cleaning machine that is easy to control, allowing workers to change the cleaning liquid as needed without replacing the liquid in the water tank, and facilitating a second rinse with clean water after a mixed liquid cleaning.

[0005] This application provides a cleaning machine that is easy to control, employing the following technical solution:

[0006] A controllable cleaning machine includes a housing; a water pump and a water tank are installed on the inner wall of the bottom end of the housing; an inlet pipe connected to the water tank is fixedly connected to the input end of the water pump, and an outlet pipe is fixedly connected to the output end of the water pump; a storage tank is installed on the inner wall of the housing; an outlet pipe is fixedly connected to the inner wall of the bottom end of the storage tank; a mixing pipe is provided inside the housing; the mixing pipe has a clean water inlet, a mixing outlet, and a connection port; the end of the clean water inlet is connected to the end of the outlet pipe away from the water pump; a drain pipe is installed on the inner wall of the mixing outlet; a washing liquid pipe connected to the inside of the mixing pipe is installed on the inner wall of the connection port; the washing liquid pipe is connected to the end of the outlet pipe away from the storage tank; a washing liquid valve core is rotatably connected to the inner wall of the washing liquid pipe; the washing liquid valve core has a connection port that connects the outlet pipe and the mixing pipe, and an adjustment mechanism is provided at the end of the washing liquid valve core extending out of the washing liquid pipe; the adjustment mechanism allows the connection port to connect the outlet pipe and the mixing pipe.

[0007] By adopting the above technical solution, in the initial state, the connection port of the washing liquid valve is closed, and the mixing pipe and the outlet pipe are not connected. When the water pump is started, the clean water in the water tank is transported to the mixing pipe through the inlet pipe and the outlet pipe. The clean water enters the drain pipe from the mixing pipe and is discharged. When it is necessary to mix the clean water and the washing liquid, the connection port is opened through the adjustment mechanism to connect the mixing pipe and the outlet pipe. This allows the washing liquid in the storage tank to enter the mixing pipe through the outlet pipe and the washing liquid pipe and mix with the clean water. As a result, the liquid discharged from the drain pipe is a mixture of clean water and washing liquid. This makes it convenient for staff to adjust the type of liquid discharged from the drain pipe according to the cleaning needs, thereby reducing the trouble of directly adding washing liquid to the water tank and enabling the washing liquid to be used for washing again with clean water after washing with washing liquid.

[0008] Preferably, the adjusting mechanism includes a pad and a connecting rod; the pad is fixedly connected to the inner wall of the housing near the washing liquid valve core, and the pad has a first through hole; a rack with both ends extending out of the first through hole is slidably connected to the inner wall of the first through hole; a push block located at the bottom of the pad is fixedly connected to the bottom end of the rack; the top surface of the push block is connected to the bottom surface of the pad through a first spring; the connecting rod is fixedly connected to the end of the washing liquid valve core extending out of the washing liquid pipe, and a gear meshing with the rack is fixedly connected to the end of the connecting rod away from the washing liquid valve core; a driving member that can push the push block upward is provided at the bottom of the push block; a fixing member that can fix the rack is provided inside the housing.

[0009] By adopting the above technical solution, in the initial state, the connecting port in the washing liquid valve core is not connected to the washing liquid pipe and the mixing pipe. The liquid flowing from the mixing pipe into the drain pipe is clean water. When it is necessary to mix washing liquid into the clean water, the driving component drives the push block to move upward. During the upward movement of the push block, the rack slides along the first through hole and drives the gear to rotate. During the rotation of the gear, the connecting rod drives the washing liquid valve core to rotate, thereby connecting the connecting port to the washing liquid pipe and the mixing pipe. This allows the washing liquid to enter the mixing pipe from the washing liquid pipe and mix with the clean water. When the rack moves to the highest point, the fixing component fixes the rack, keeping the connecting port open and facilitating the mixing of washing liquid and clean water.

[0010] Preferably, the bottom surface of the push block is provided with an arc surface; the driving component includes a motor; the motor is mounted on the outer wall of the housing, and a rotating shaft extending to the bottom of the push block is fixedly connected to the output end of the motor; a cam that can contact and cooperate with the arc surface is fixedly connected to the outer wall of the rotating shaft.

[0011] By adopting the above technical solution, the starting motor drives the rotating shaft to rotate. During the rotation of the rotating shaft, the cam rotates. When the cam contacts the arc surface on the push block, the cam and the arc surface work together to push the push block upward, thereby causing the push block to drive the rack upward.

[0012] Preferably, the housing has a second through hole on the side wall near the rack; the fixing member includes a fixing block and a rod slidably connected in the second through hole; the fixing block is fixed to the side wall of the rack away from the washing liquid valve core; the end of the rod extending into the housing has an inclined surface, and the end of the rod outside the housing is fixed to a pull plate; the pull plate is connected to the side wall of the rod and connected to the outer wall of the housing by a second spring; the top surface of the fixing block near the rod has a rounded corner that contacts and engages with the inclined surface, and the side wall of the fixing block away from the rack has a slot for embedding the rod to fix the fixing block.

[0013] By adopting the above technical solution, during the rotation of the cam, the cam and the arc surface work together to make the cam press the pusher block slide upward. During the upward sliding of the pusher block, the rack and the fixed block are driven to move upward. During the upward movement of the fixed block, the rounded corner and the inclined surface work together to make the fixed block press the insert rod slide along the second through hole away from the fixed block. During the sliding of the insert rod, the second spring is stretched. When the cam presses the pusher block to the highest point, the insert rod is aligned with the slot. Under the elastic force of the second spring, the insert rod is embedded in the slot to fix the fixed block, so that the fixed block and the rack remain stable.

[0014] Preferably, a flexible hose communicating with the interior of the housing is fixedly connected to the outer wall of the housing; a cleaning head is fixedly connected to the end of the flexible hose away from the housing; a water passage chamber is provided inside the cleaning head; a spray nozzle communicating with the interior of the water passage chamber is fixedly connected to the inner wall of the bottom end of the water passage chamber; a mixing tank is fixedly connected to the inner wall of the bottom end of the housing; the end of the drain pipe away from the mixing pipe communicates with the interior of the mixing tank; a water supply pipe is fixedly connected to the side wall of the mixing tank; the end of the water supply pipe away from the mixing tank extends into the flexible hose and communicates with the interior of the water passage chamber; a first rotating shaft is rotatably connected to the inner wall of the mixing tank; a stirring plate is fixedly connected to the outer wall of the first rotating shaft; and a first transmission component is provided on the rotating shaft to drive the first rotating shaft to rotate.

[0015] By adopting the above technical solution, during the rotation of the rotating shaft, the first rotating shaft and the stirring plate are driven to rotate by the first transmission component. When the washing liquid flows out of the washing liquid pipe and enters the mixing pipe, it enters the mixing tank through the drain pipe. The stirring plate stirs the mixture of washing liquid and clean water, so as to promote the washing liquid and clean water to be fully mixed. The mixed liquid enters the water passage chamber inside the cleaning head through the water supply pipe. The mixed liquid in the water passage chamber is then sprayed out through the nozzle, which makes it easier for the cleaning head to clean the dirt.

[0016] Preferably, the end of the first rotating shaft near the motor extends out of the mixing chamber; the first transmission component includes a first pulley, a second pulley, and a belt; the first pulley is fixed to the outer wall of the rotating shaft; the second pulley is fixed to the end of the first rotating shaft extending out of the mixing chamber; the belt is sleeved on the outside of the first pulley and the second pulley, and the belt causes the first pulley and the second pulley to move together.

[0017] By adopting the above technical solution, the first rotating shaft rotates during the rotation of the rotating shaft through the transmission action of the first pulley, the second pulley and the belt, thereby realizing that the first rotating shaft rotates synchronously during the rotation of the rotating shaft.

[0018] Preferably, a second rotating shaft is rotatably connected to the inner wall of the mixing tube; the top end of the second rotating shaft extends into the connection port, the bottom end of the second rotating shaft extends to the bottom of the mixing tube, a spiral blade is fixed to the outer wall of the second rotating shaft extending into the connection port, and a second transmission component is provided at the bottom end of the second rotating shaft to drive the rotating shaft to rotate.

[0019] By adopting the above technical solution, the rotating shaft is driven to rotate by the transmission action of the second transmission component during the rotation of the rotating shaft. During the rotation of the second rotating shaft, the spiral blades are driven to rotate, which causes the washing liquid to flow from the washing liquid pipe into the mixing pipe and mix with the clean water. This makes it difficult for the washing liquid to adhere to the inner wall of the washing liquid pipe. At the same time, the spiral blades also stir the washing liquid and clean water during the rotation, which promotes the mixing of the washing liquid and clean water.

[0020] Preferably, the second transmission component includes a first bevel gear fixedly connected to the bottom end of the second rotating shaft; the end of the rotating shaft away from the motor is fixedly connected to a second bevel gear that meshes with the first bevel gear.

[0021] By adopting the above technical solution, the rotating shaft drives the second bevel gear to rotate during the rotation process. Under the meshing cooperation of the first bevel gear and the second bevel gear, the rotating shaft drives the second bevel gear to rotate, so that the rotating shaft drives the second rotating shaft to rotate synchronously.

[0022] Preferably, a one-way valve is provided on the inner wall of the communication port.

[0023] By adopting the above technical solution, the one-way valve prevents the clean water in the mixing pipe from flowing back into the storage tank through the connection port, thus preventing the washing liquid in the storage tank from being diluted.

[0024] Preferably, the outer wall of the washing liquid valve core that contacts the inner wall of the washing liquid pipe is provided with a first sealing groove; a first sealing ring is provided in the first sealing groove; the outer wall of the washing liquid pipe that contacts the inner wall of the connection port is provided with a second sealing groove; a second sealing ring is provided in the second sealing groove; the outer wall of the drain pipe that contacts the inner wall of the mixing port is provided with a third sealing groove; a third sealing ring is provided in the third sealing groove.

[0025] By adopting the above technical solution, the first sealing ring, the second sealing ring, and the third sealing ring ensure that the washing liquid valve core, washing liquid pipe, mixing pipe, and drain pipe have a good sealing and leak-proof effect after connection and installation, reducing the possibility of liquid leakage.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. When detergent cleaning is required, the motor is started, driving the rotating shaft to rotate, causing the cam to press the pusher block upwards. During the upward movement of the pusher block, the rack and fixed block are also moved upwards. The rack drives the gear to rotate, opening the outlet pipe and mixing pipe of the detergent valve core, allowing the detergent to enter the mixing pipe and mix with clean water. At this time, the liquid discharged from the drain pipe is the mixed liquid. During the upward movement of the fixed block, the pusher rod slides and stretches the second spring. When the cam presses the pusher block to its highest point, the pusher rod is inserted into the slot to fix the fixed block, keeping the rack stable. The connecting port remains open, allowing the washing liquid to continuously mix with clean water. After the mixed liquid cleaning is completed, the motor is turned off, causing the cam to stop rotating. Then, the pull plate is pulled to remove the insert rod from the slot. Under the elastic force of the first spring, the push block drives the rack and the fixing block to move down. The gear reverses, causing the connecting port to no longer connect the outlet pipe and the mixing pipe. At this time, the washing liquid is no longer added to the mixing pipe, and the liquid discharged from the drain pipe is clean water. This facilitates a second clean water cleaning after the washing liquid cleaning, reducing the hassle of directly adding the washing liquid to the water tank.

[0028] 2. During the rotation of the rotating shaft, the second bevel gear is driven to rotate. The cooperation between the first and second bevel gears causes the second rotating shaft to rotate. During the rotation of the second rotating shaft, the spiral blades are driven to rotate. The rotation of the spiral blades causes the washing liquid to flow into the mixing pipe and mix with the clean water, making it less likely for the washing liquid to adhere to the inner wall of the washing liquid pipe. In addition, the spiral blades also play a role in stirring the washing liquid and clean water during the rotation, promoting the mixing of the washing liquid and clean water.

[0029] 3. During the rotation of the rotating shaft, the first rotating shaft rotates under the transmission action of the first pulley, the second pulley and the belt. The first rotating shaft drives the stirring plate to rotate. The stirring action of the stirring plate stirs the mixture of washing liquid and clean water flowing into the mixing tank, so as to promote the washing liquid and clean water to be fully mixed.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0040] This invention discloses a cleaning machine that is easy to control, such as... Figure 1 and Figure 2As shown, the system includes a housing 1, a water tank 3, a storage tank 4, a mixing pipe 5, a washing liquid pipe 55, and a washing liquid valve core 56. The water tank 3 is fixed to the inner wall of the bottom end of the housing 1, and a water inlet 31 communicating with the inside of the water tank 3 is fixed to the top surface of the water tank 3. The storage tank 4 is fixed to the inner wall of the housing 1, and an inlet 42 communicating with the inside of the storage tank 4 is fixed to the top surface of the storage tank 4. An outlet pipe 41 communicating with the inside of the storage tank 4 is fixed to the inner wall of the bottom end of the storage tank 4. The mixing pipe 5 is located at the bottom of the storage tank 4, and the mixing pipe 5 is provided with a mixing port 52, a connection port 53, and a clean water port 51. A drain pipe 54 communicating with the inside of the mixing pipe 5 is installed on the inner wall of the mixing port 52. The washing liquid pipe... 55 is installed on the inner wall of the connection port 53. The washing liquid pipe 55 is connected to the inside of the mixing pipe 5. The end of the outlet pipe 41 away from the storage tank 4 is fixed to the side wall of the washing liquid pipe 55 and is connected to the inside of the washing liquid pipe 55. The washing liquid valve core 56 is rotatably connected to the inner wall of the washing liquid pipe 55. The washing liquid valve core 56 can conduct the outlet pipe 41 and the mixing pipe 5. A water pump 2 is fixed to the inner wall of the bottom end of the housing 1. The water inlet pipe 21 is fixed to the input end of the water pump 2. The water outlet pipe 22 is fixed to the output end of the water pump 2. The end of the water inlet pipe 21 away from the water pump 2 extends into the water tank 3 and is connected to the water tank 3. The end of the water outlet pipe 22 away from the water pump 2 is fixed to the end of the clean water outlet 51 and is connected to the inside of the mixing pipe 5.

[0041] The washing liquid and clean water are injected into the storage tank 4 and water tank 3 respectively through the inlet 42 and the water inlet 31. The water pump 2 is started to transport the clean water in the water tank 3 to the mixing pipe 5 through the inlet pipe 21 and the outlet pipe 22. When the washing liquid valve core 56 is not connected to the outlet pipe 41 and the mixing pipe 5, the liquid discharged from the drain pipe 54 is clean water. When the washing liquid valve core 56 connects the outlet pipe 41 and the mixing pipe 5, the washing liquid enters the mixing pipe 5 through the outlet pipe 41 and mixes with the clean water. This allows the washing liquid and clean water to mix in the mixing pipe 5, so that the liquid discharged from the drain pipe 54 is a mixture of washing liquid and clean water. This reduces the trouble of directly adding washing liquid to the water tank 3 and makes it convenient to rinse with clean water again after washing with washing liquid.

[0042] like Figure 2 and Figure 3As shown, a flexible hose 12 communicating with the interior of the housing 1 is fixedly connected to the outer wall of the housing 1. A cleaning head 13 is fixedly connected to the end of the flexible hose 12 away from the housing 1. A cleaning brush 132 is provided on the bottom surface of the cleaning head 13. A water passage chamber 131 is provided inside the cleaning head 13. Multiple nozzles 14 extending into the cleaning brush 132 are fixedly connected to the inner wall of the bottom end of the water passage chamber 131. The nozzles 14 are communicating with the interior of the water passage chamber 131. A mixing tank 7 is fixedly connected to the inner wall of the bottom end of the housing 1. A water supply pipe 71 communicating with the interior of the mixing tank 7 is fixedly connected to the outer wall of the mixing tank 7. The end of the water supply pipe 71 away from the mixing tank 7 extends into the flexible hose 12 and is fixedly connected to the side wall of the cleaning head 13. The water supply pipe 71 is communicating with the interior of the water passage chamber 131. The end of the drain pipe 54 away from the mixing pipe 5 is fixedly connected to the side wall of the mixing tank 7 and communicates with the interior of the mixing tank 7.

[0043] The liquid flowing out of the drain pipe 54 first enters the mixing tank 7, then enters the water passage chamber 131 in the cleaning head 13 through the water supply pipe 71, and finally is sprayed out through the nozzle 14 to achieve the cleaning work. The hose 12 protects the water supply pipe 71, making the water supply pipe 71 less likely to be damaged. The cleaning brush 132 on the bottom surface of the cleaning head 13 facilitates the cleaning head 13 to clean the dirt.

[0044] like Figure 2 and Figure 4 As shown, the washing liquid valve core 56 is provided with a connecting port 561 that connects the liquid outlet pipe 41 and the mixing pipe 5. A one-way valve 562 is provided on the inner wall of the connecting port 561. An annular first sealing groove 563 is provided on the outer wall of the washing liquid valve core 56 that contacts the inner wall of the washing liquid pipe 55. A first sealing ring 564 is fixedly connected in the first sealing groove 563. An annular second sealing groove 551 is provided on the outer wall of the washing liquid pipe 55 that contacts the inner wall of the connecting port 53. A second sealing ring 552 is fixedly connected on the inner wall of the second sealing groove 551. An annular third sealing groove 541 is provided on the outer wall of the drain pipe 54 that contacts the inner wall of the mixing port 52. A third sealing ring 542 is fixedly connected in the third sealing groove 541.

[0045] When the connecting port 561 connects the liquid outlet pipe 41 and the mixing pipe 5, the washing liquid enters the mixing pipe 5 and mixes with the clean water. The one-way valve 562 installed in the connecting port 561 makes the connecting port 561 unidirectional, making it difficult for clean water to enter the liquid outlet pipe 41 and dilute the washing liquid. The first sealing ring 564, the second sealing ring 552 and the third sealing ring 542 make it difficult for the liquid to leak during the flow process.

[0046] like Figure 2 , Figure 4 and Figure 5As shown, the end of the washing liquid valve core 56 extending out of the washing liquid pipe 55 is provided with an adjusting mechanism 6 that allows the connecting port 561 to connect the liquid outlet pipe 41 and the mixing pipe 5. The adjusting mechanism 6 includes a pad 61, a push block 64, a rack 63, a gear 66, a connecting rod 62, a driving member 67 that can push the push block 64 upward, and a fixing member 68 that can fix the rack 63. The connecting rod 62 is fixedly connected to the end of the washing liquid valve core 56 extending out of the washing liquid pipe 55, the gear 66 is fixedly connected to the end of the connecting rod 62 away from the washing liquid valve core 56, and the pad 61 is fixedly connected to the housing. On the inner wall near the gear 66, the top surface of the pad 61 is provided with a first through hole 611. The rack 63 is slidably connected in the first through hole 611. The top end of the rack 63 extends to the top of the pad 61, and the bottom end of the rack 63 extends to the bottom end of the pad 61. The rack 63 meshes with the gear 66. The push block 64 is fixedly connected to the bottom end of the rack 63. The top surface of the push block 64 is fixedly connected with a first spring 65. The end of the first spring 65 away from the push block 64 is fixedly connected to the bottom surface of the pad 61. The driving member 67 is provided at the bottom of the push block 64, and the fixing member 68 is provided on the side of the rack 63 away from the washing liquid valve core 56.

[0047] When the connecting port 561 is not connected to the outlet pipe 41, the liquid discharged from the drain pipe 54 is clean water. When it is necessary to add washing liquid to the clean water, the drive component 67 pushes the push block 64 to move upward. During the upward movement of the push block 64, the first spring 65 is compressed and the rack 63 is driven to move upward. During the movement of the rack 63, the gear 66 and the connecting rod 62 are driven to rotate, so that the connecting port 561 connects the outlet pipe 41 and the mixing pipe 5, so that the washing liquid can enter the mixing pipe 5 and mix with the clean water. When the connecting port 561 connects the outlet pipe 41 and the mixing pipe 5, the rack 63 is fixed by the fixing component 68 so that the washing liquid can flow out continuously.

[0048] like Figure 4 and Figure 5 As shown, the drive unit 67 includes a motor 671 and a cam 673 that can contact the push block 64; the motor 671 is mounted on the outer wall of the housing 1, and the output end of the motor 671 is fixedly connected to a rotating shaft 672 that extends to the bottom of the push block 64; the cam 673 is fixedly connected to the side wall of the rotating shaft, and the bottom surface of the push block 64 is provided with an arc surface 641 that can cooperate with the cam 673.

[0049] When detergent needs to be added, the motor 671 is started to drive the rotating shaft 672 and the cam 673 to rotate. When the cam 673 contacts the arc surface 641, the cam 673 pushes the push block 64 to move upward, which causes the push block 64 to drive the rack 63 to move upward, so that the rack 63 can drive the gear 66 to rotate, thereby allowing the connecting port 561 to connect the liquid outlet pipe 41 and the mixing pipe 5.

[0050] like Figure 2 , Figure 5 and Figure 6As shown, the housing 1 has a second through hole 11 on the side wall near the rack 63; the fixing member 68 includes a fixing block 681 fixed to the side wall of the rack 63 away from the washing liquid valve core 56 and a plug rod 682 slidably connected in the second through hole 11; one end of the plug rod 682 is located outside the housing 1, and the other end extends into the housing 1 to contact the fixing block 681. The end of the plug rod 682 that contacts the fixing block 681 has a bevel 683. The end of the plug rod 682 that extends outside the housing 1 is fixed to a pull plate 684. A second spring 685 is fixed to the side wall of the pull plate 684 near the housing 1. The end of the second spring 685 that is away from the pull plate 684 is fixed to the outer side wall of the housing 1; the top surface of the fixing block 681 has a rounded corner 686 on the side wall near the plug rod 682 that contacts and cooperates with the bevel 683. The side wall of the fixing block 681 away from the rack 63 has a slot 687 for inserting the plug rod 682 to fix the fixing block 681.

[0051] Through the cooperation of the rounded corner 686 and the inclined surface 683, the fixing block 681 squeezes the insertion rod 682 along the second through hole 11 away from the fixing block 681 during the upward movement and stretches the second spring 685. When the rack 63 moves to the highest point, the insertion rod 682 aligns with the slot 687. Under the elastic force of the second spring 685, the insertion rod 682 is embedded in the slot 687 to fix the fixing block 681, so that the rack 63 remains stable, which facilitates the flow of washing liquid and mixing with the cleaning liquid.

[0052] like Figure 7 and Figure 8 As shown, a second rotating shaft 57 is rotatably connected to the inner wall of the mixing pipe 5; the top end of the second rotating shaft 57 extends into the connection port 53, and a spiral blade 571 is fixed to the outer wall of the second rotating shaft 57 extending into the connection port 53; the bottom end of the second rotating shaft 57 extends to the bottom of the mixing pipe 5; a second transmission component 58 is provided at the bottom end of the second rotating shaft 57, which can drive the rotating shaft 672 to rotate the second rotating shaft 57; the second transmission component 58 includes a first bevel gear 581 and a second bevel gear 582 meshing with the first bevel gear 581; the first bevel gear 581 is fixed to the end of the rotating shaft 672 away from the motor 671; and the second bevel gear 582 is fixed to the bottom end of the second rotating shaft 57.

[0053] During the rotation of the rotating shaft 672, the meshing of the first bevel gear 581 and the second bevel gear 582 causes the second rotating shaft 57 and the spiral blade 571 to rotate. The rotation of the spiral blade 571 not only makes it difficult for the washing liquid to adhere to the inner wall of the washing liquid pipe 55, but also plays a stirring role for the washing liquid that has been initially mixed with clean water, so as to promote better mixing of the washing liquid with clean water to form a cleaning liquid.

[0054] like Figure 7 and Figure 8As shown, a first rotating shaft 72 is rotatably connected to the inner wall of the mixing tank 7; a pair of stirring plates 721 are fixed to the outer wall of the first rotating shaft 72; the end of the rotating shaft 672 near the motor 671 extends out of the mixing tank 7, and the end of the rotating shaft 672 extending out of the mixing tank 7 is provided with a first transmission member 8 that can drive the first rotating shaft 72 to rotate. The first transmission member 8 includes a first pulley 81, a second pulley 82 and a belt 83; the first pulley 81 is fixed to the outer wall of the rotating shaft 672; the second pulley 82 is fixed to the end of the first rotating shaft 72 extending out of the mixing tank 7; the belt 83 is sleeved on the outside of the first pulley 81 and the second pulley 82, and the belt 83 makes the first pulley 81 and the second pulley 82 move together.

[0055] During the rotation of the rotating shaft 672, the first rotating shaft 72 drives the stirring plate 721 to rotate under the transmission action of the first pulley 81, the second pulley 82 and the belt 83. The stirring plate 721 stirs the mixture of washing liquid and clean water flowing into the mixing tank 7, so as to promote the washing liquid and clean water to be fully mixed and improve the cleaning effect.

[0056] Working principle: Washing liquid and clean water are injected into the storage tank 4 and water tank 3 respectively through the liquid inlet 42 and water replenishment port 31. In the initial state, the connection port 561 of the washing liquid valve core 56 is closed. The washing liquid in the storage tank 4 enters the washing liquid pipe 55 through the liquid outlet pipe 41 and does not flow into the mixing pipe 5. The water pump 2 is started to transport the clean water in the water tank 3 to the mixing pipe 5 through the water inlet pipe 21 and the water outlet pipe 22. The clean water enters the mixing box 7 from the mixing pipe 5 through the liquid outlet pipe 54. The clean water in the mixing box 7 enters the water passage chamber 131 of the cleaning head 13 through the water supply pipe 71, so that the liquid sprayed from the nozzle 14 is clean water.

[0057] When detergent needs to be added, the motor 671 is started, driving the rotating shaft 672 to rotate. During this rotation, the rotating shaft 672 drives the cam 673 to rotate. Through the interaction between the cam 673 and the arc surface 641, the cam 673 presses the push block 64 upwards. As the push block 64 moves upwards, it drives the rack 63 and the fixing block 681 upwards. The rack 63's upward movement drives the gear 66 to rotate, which in turn drives the connecting rod 62 and the detergent valve core 56 to rotate. This causes the connecting port 561 of the detergent valve core 56 to open the outlet pipe 41 and the mixing pipe 5, allowing the detergent to enter the mixing pipe 5 and mix with clean water. Mixing; During the upward movement of the fixed block 681, the cooperation between the rounded corner 686 and the inclined surface 683 causes the fixed block 681 to press the insertion rod 682 to slide along the second through hole 11 away from the fixed block 681 and stretch the second spring 685. When the cam 673 presses the push block 64 to move to the highest point, the insertion rod 682 aligns with the slot 687. Under the elastic force of the second spring 685, the insertion rod 682 is embedded in the slot 687 to fix the fixed block 681, so that the rack 63 remains stable and the connecting port 561 remains open, thereby allowing the washing liquid to continuously mix with the clean water;

[0058] A one-way valve 562 is installed inside the connecting port 561 to make the connecting port 561 unidirectional, so that clean water is not easily backflowed into the liquid storage tank 4 and diluted with washing liquid.

[0059] During the rotation of the rotating shaft 672, the second bevel gear 582 is driven to rotate. Under the meshing of the first bevel gear 581 and the second bevel gear 582, the rotating shaft 672 drives the second rotating shaft 57 and the spiral blade 571 to rotate. The rotation of the spiral blade 571 causes the washing liquid to flow into the mixing pipe 5 and mix with the clean water, so that the washing liquid is not easy to adhere to the inner wall of the washing liquid pipe 55. In addition, the spiral blade 571 also plays a role in stirring the washing liquid and clean water during the rotation, promoting the mixing of the washing liquid and clean water.

[0060] During the rotation of the rotating shaft 672, the first rotating shaft 72 rotates under the transmission action of the first pulley 81, the second pulley 82 and the belt 83, thereby causing the stirring plate 721 to rotate. The stirring plate 721 stirs the mixture of washing liquid and clean water flowing into the mixing tank 7, so as to promote the washing liquid and clean water to be fully mixed.

[0061] After the detergent cleaning is completed, the motor 671 is turned off, causing the cam 673 to stop rotating. Then, the pull plate 684 is pulled to remove the insert rod 682 from the slot 687. Under the elastic force of the first spring 65, the push block 64 drives the rack 63 and the fixing block 681 to move down. During the downward movement of the rack 63, the connecting rod 62 drives the detergent valve core 56 to rotate in the opposite direction to the initial position, so that the connecting port 561 no longer connects the liquid outlet pipe 41 and the mixing pipe 5, and the detergent is no longer added to the mixing pipe 5. Thus, the liquid discharged from the drain pipe 54 is clean water, which makes it easy to perform a clean water cleaning after the detergent cleaning.

[0062] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
