[0040] The waterway system includes a power device (such as a water pump), an inlet pipe and an outlet pipe, the power device is used to realize water pumping and draining, the inlet pipe and the outlet pipe are communicated with the power device and are respectively used for water inlet and water outlet, and in order to control the opening and closing of the pipes, valves are arranged on the inlet pipe and the outlet pipe.

[0041] In the related art, when water pumping and draining is needed, the power device needs to be started first, and then the valve on the inlet pipe is opened and the valve on the outlet pipe is closed, or the valve on the inlet pipe is closed and the valve on the outlet pipe is opened, so that the steps of water pumping and draining are relatively cumbersome and the efficiency is relatively low.

[0042] Therefore, the embodiments of the present application provide a waterway system, a cleaning base station and a cleaning system, which can at least solve the technical problem of relatively cumbersome steps and low efficiency of water pumping and draining to a certain extent.

[0043] The present application will be described below in conjunction with the drawings and specific embodiments:

[0044] Figure 1 The structure schematic diagram of the cleaning base station in the embodiments of the present application is shown, Figure 2 The structure schematic diagram of the cleaning base station in the embodiments of the present application is shown, Figure 1 The structure schematic diagram of the cleaning base station in the embodiments of the present application is shown, Figure 3 The structure schematic diagram of the cleaning base station in the embodiments of the present application is shown, Figure 1 The structure schematic diagram of the waterway system in the embodiments of the present application is shown, please refer to Figures 1-3The embodiment of the present application provides a water system 10, which can realize the opening of the water inlet valve 300 and the closing of the water outlet valve 400, or the closing of the water inlet valve 300 and the opening of the water outlet valve 400, by simply controlling the movement of the driving mechanism 500, without the need to separately control the opening and closing of the water inlet valve 300 and the water outlet valve 400, thereby reducing the steps of pumping and drainage and improving the efficiency of pumping and drainage.

[0045] See also Figure 2 and Figure 3 The embodiment of the present application provides a water system 10, comprising an inlet pipe 100, an outlet pipe 200, an inlet valve 300, an outlet valve 400, and a drive mechanism 500. The inlet pipe 100 is in communication with the outlet pipe 200, the inlet valve 300 is disposed on the inlet pipe 100, and the outlet valve 400 is disposed on the outlet pipe 200. The drive mechanism 500 is in communication with the inlet pipe 100 and the outlet pipe 200. The movement of the drive mechanism 500 can cause the inlet valve 300 to open and the outlet valve 400 to close, or the inlet valve 300 to close and the outlet valve 400 to open.

[0046] The water inlet valve 300 is used to connect or disconnect the water inlet pipe 100 and the driving mechanism 500, and the water outlet valve 400 is used to connect or disconnect the water outlet pipe 200 and the driving mechanism 500. The driving mechanism 500 is used to generate power to transport external water into the water system 10 through the water inlet pipe 100 to achieve water pumping when the water inlet valve 300 is open, and to transport water in the water system 10 to the outside through the water outlet pipe 200 to achieve water drainage when the water outlet valve 400 is open.

[0047] The water inlet pipe 100 can be connected to a container containing liquid. When the driving mechanism 500 pumps water, the water inlet valve 300 needs to be opened so that the water in the container can be transported to the water system 10 through the water inlet pipe 100, and the water outlet valve 400 needs to be closed to prevent external air or impurities from being transported into the water system 10; when the driving mechanism 500 drains water, the water outlet valve 400 needs to be opened so that the water in the water system 10 can be discharged through the water outlet pipe 200, and the water inlet valve 300 needs to be closed to prevent the water in the water system 10 from flowing back into the container. Therefore, whether pumping water or draining water, the water inlet valve 300 and the water outlet valve 400 need to keep one open and the other closed. Since the movement of the driving mechanism 500 can open the water inlet valve 300 and close the water outlet valve 400; or close the water inlet valve 300 and open the water outlet valve 400, that is, the movement of the driving mechanism 500 is linked to the switching of the water inlet valve 300 and the water outlet valve 400, it is only necessary to control the movement of the driving mechanism 500 to make the water inlet valve 300 open and the water outlet valve 400 closed at the same time, or to close the water inlet valve 300 and the water outlet valve 400 open at the same time, so as to realize pumping or draining water, without the need to separately control the switching of the water inlet valve 300 and the water outlet valve 400, thereby reducing the steps of pumping and draining water and improving the efficiency of pumping and draining water.

[0048] In some embodiments, Figure 4 It is shown Figure 3 A cross-sectional view of the driving mechanism is shown in FIG. 5, and a perspective view of the driving mechanism is shown in FIG. 6. Figure 3 and Figure 4 The driving mechanism 500 includes a driving assembly 510, a housing 520, and a piston 530, the piston 530 is arranged in the housing 520, the driving assembly 510 is in driving connection with the piston 530, and the water inlet pipe 100 and the water outlet pipe 200 are in communication with the housing 520.

[0049] The driving assembly 510 is used to drive the piston 530 to reciprocate in the housing 520 along the axial direction of the housing 520, and the housing 520 can be cylindrical, cuboid, etc., and is not limited in this regard. The movement of the piston 530 in the housing 520 can make the water inlet valve 300 open and the water outlet valve 400 close, or the water inlet valve 300 close and the water outlet valve 400 open, i.e. only by controlling the driving assembly 510 to drive the piston 530 to move, the water inlet valve 300 can be opened at the same time as the water outlet valve 400 is closed, or the water inlet valve 300 can be closed at the same time as the water outlet valve 400 is opened, so as to realize water pumping or water draining, without the need to separately control the opening and closing of the water inlet valve 300 and the water outlet valve 400, thereby reducing the steps of water pumping and draining, and improving the efficiency of water pumping and draining.

[0050] Moreover, the water inlet valve 300 and the water outlet valve 400 can be opened or closed by the movement of the piston 530, without the need for electromagnetic control, thereby reducing the use of electromagnetic valves and simplifying the structure of the waterway system 10 as a whole.

[0051] In some embodiments, under the condition that the piston 530 moves in a first direction, the water inlet valve 300 is opened and the water outlet valve 400 is closed; under the condition that the piston 530 moves in a second direction, the water inlet valve 300 is closed and the water outlet valve 400 is opened.

[0052] Obviously, the first direction is opposite to the second direction. Since the water inlet valve 300 being opened and the water outlet valve 400 being closed and the water inlet valve 300 being closed and the water outlet valve 400 being opened are two completely opposite states, the two different states can be realized by the piston 530 moving in two opposite directions. That is, when water pumping is needed, the driving assembly 510 drives the piston 530 to move in the first direction, and when water draining is needed, the driving assembly 510 drives the piston 530 to move in the second direction.

[0053] In some embodiments, the housing 520 can accommodate water flowing in from the water inlet pipe 100, and the water in the housing 520 can be drained through the water outlet pipe 200.

[0054] The movement of the driving mechanism 500 causes the water inlet valve 300 to open while the water outlet valve 400 is closed, or the water inlet valve 300 is closed while the water outlet valve 400 is opened. When the water inlet valve 300 is opened, external water enters the driving mechanism 500 through the water inlet pipe 100. Since the water outlet valve 400 is closed, the water cannot be immediately discharged, and thus needs to be temporarily stored in the driving mechanism 500. Until the driving mechanism 500 moves to cause the water inlet valve 300 to close and the water outlet valve 400 to open, the water in the driving mechanism 500 can be discharged through the water outlet pipe 200. The housing 520 is a component for containing water in the driving mechanism 500. That is, when the water inlet pipe 100 is connected to the water outlet pipe 200, the water in the water inlet pipe 100 can be stored in the housing 520 until the driving mechanism 500 moves to cause the water inlet valve 300 to close and the water outlet valve 400 to open, so that the water in the housing 520 can be discharged through the water outlet pipe 200.

[0055] In some embodiments, the piston 530 divides the housing 520 into a water-containing cavity 521 and a water-free cavity 522. The water inlet pipe 100 and the water outlet pipe 200 are connected to the water-containing cavity 521, and part of the driving assembly 510 is arranged in the water-free cavity 522.

[0056] The water inlet pipe 100 and the water outlet pipe 200 are connected to the water-containing cavity 521, that is, the water-containing cavity 521 is a component for containing water when water is pumped or discharged. When water is pumped, the water in the water-containing cavity 521 enters the housing 520. When water is discharged, the water in the water-containing cavity 521 is discharged through the water outlet pipe 200. Part of the driving assembly 510 is arranged in the water-free cavity 522, which can prevent the driving assembly 510 from interfering with the water inlet pipe 100 and the water outlet pipe 200.

[0057] In addition, since the water-containing cavity 521 is used to contain water, and part of the driving assembly 510 is arranged in the water-free cavity 522, that is, the functions of driving and water tank are integrated in the housing 520, the space occupancy of the water system 10 as a whole can be small.

[0058] For the convenience of description, the opposite ends of the housing 520 are respectively named as a first end 523 and a second end 524. The water-containing cavity 521 is arranged close to the first end 523, and the water-free cavity 522 is arranged close to the second end 524. When the piston 530 moves from the first end 523 to the second end 524, the volume of the water-containing cavity 521 gradually increases, and the volume of the water-free cavity 522 gradually decreases. The air in the water-free cavity 522 is compressed to be under positive pressure, and thus the water-containing cavity 521 is under negative pressure. External water can be pumped into the water-containing cavity under the suction of the negative pressure. When the piston 530 moves from the second end 524 to the first end 523, the volume of the water-free cavity 522 gradually increases, and the volume of the water-containing cavity 521 gradually decreases. The air in the water-containing cavity 521 is compressed to be under positive pressure, and thus the water in the water-containing cavity 521 can be discharged under the extrusion of the piston 530 to realize water discharge.

[0059] That is, when water needs to be pumped, the piston 530 needs to be moved from the first end 523 to the second end 524, and when water needs to be drained, the piston 530 needs to be moved from the second end 524 to the first end 523. Since the water inlet valve 300 is opened and the water outlet valve 400 is closed when the piston 530 moves in the first direction, and the water inlet valve 300 is closed and the water outlet valve 400 is opened when the piston 530 moves in the second direction, the first direction is the direction in which the first end 523 moves towards the second end 524, and the second direction is the direction in which the second end 524 moves towards the first end 523.

[0060] In some embodiments, Figure 5 It is shown Figure 3 The structure of the water inlet valve and the water inlet pipe in the middle is shown in FIG. 2. Please refer to Figures 3-5 The water inlet valve 300 includes a first valve body 310 and a first valve core 320 arranged in the first valve body 310. The first valve body 310 has a first water inlet 311 and a first water outlet 312, and the first water outlet 312 is in communication with the shell 520. The first valve core 320 can communicate or block the first water inlet 311 and the first water outlet 312 under the condition that the piston 530 moves.

[0061] The first valve core 320 can be made of elastic materials such as rubber and silicone. The first water inlet 311 and the first water outlet 312 can be arranged oppositely. During the movement of the piston 530 in the shell 520, the air pressure in the shell 520 changes. Since the first water outlet 312 is in communication with the shell 520, the air pressure in the first valve body 310 also changes, causing the first valve core 320 to deform under the action of the air pressure, thereby communicating or blocking the first water inlet 311 and the first water outlet 312.

[0062] In some embodiments, the first valve core 320 has a first opening 321 and a second opening 322 in communication with the first opening 321. The first opening 321 is in communication with the first water inlet 311, and the second opening 322 can be opened or closed under the condition that the piston 530 moves.

[0063] The first opening 321 is arranged close to the first water inlet 311, and the second opening 322 is arranged close to the first water outlet 312. There may be a gap between the second opening 322 and the first water outlet 312, or they may fit together, and there is no restriction on this. Since the first water outlet 312 is connected to the shell 520, when the piston 530 moves along the first direction, the volume of the water cavity 521 increases and the pressure decreases, and the pressure in the first valve body 310 also decreases accordingly, and is lower than the pressure inside the first valve core 320, so that the pressure inside the first valve core 320 is greater than the pressure outside. Since the first valve core 320 is elastic, the first valve core 320 will be pushed outward under the action of the pressure inside, so that the second opening 322 opens, and the first valve core 320 is connected to the first water inlet 31. 1 and the first water outlet 312; when the piston 530 moves along the second direction, the volume of the water cavity 521 decreases and the pressure increases, and the pressure in the first valve body 310 also increases accordingly, and is greater than the pressure inside the first valve core 320, so that the pressure outside the first valve core 320 is greater than the pressure inside. Since the first valve core 320 is elastic, the first valve core 320 will be squeezed inwardly under the action of the pressure outside, so that the second opening 322 is closed, so that the first valve core 320 cuts off the first water inlet 311 and the first water outlet 312.

[0064] Specifically, Figure 6 Shown Figure 5 For the structural diagram of the first valve core, please refer to Figure 5 and Figure 6 The first valve core 320 has a first channel 323 that is connected to both the first opening 321 and the second opening 322, and the first channel 323 has two first side walls 324 arranged opposite to each other. The two first side walls 324 enclose the second opening 322. When the first valve core 320 is squeezed inward under the action of external pressure, the two first side walls 324 move relative to each other and press together, so that the second opening 322 is closed; when the first valve core 320 is stretched outward under the action of external pressure, the two first side walls 324 separate, so that the second opening 322 is opened.

[0065] It should be noted that the size of the first opening 321 is much larger than the size of the second opening 322. When the first valve core 320 is squeezed inward under the action of external pressure, the second opening 322 will be closed under the action of the pressure difference. At the same time, the first opening 321 will also undergo a certain deformation, but the deformation is not enough to make the first opening 321 completely closed, so it does not affect the connection between the first opening 321 and the first water inlet 311.

[0066] In some embodiments, the first valve core 320 is fixedly connected to the first valve body 310 .

[0067] Since the first water outlet 312 is in communication with the shell 520, i.e. in the direction of the water inlet pipe 100, the first water outlet 312 is closer to the shell 520 than the first water inlet 311, thus when the piston 530 moves in the first direction, the volume of the water cavity 521 increases, and the pressure decreases, the pressure of the first water outlet 312 will decrease first than the first water inlet 311, i.e. the pressure of the first water inlet 311 is greater than the pressure of the first water outlet 312, since air flows from the place with high air pressure to the place with low air pressure, thus the first valve core 320 will have a tendency to move to the first water outlet 312 under the action of pressure difference, causing the first opening 321 to separate from the first water inlet 311. Therefore, the fixed connection of the first valve core 320 and the first valve body 310 can to some extent avoid the movement of the first valve core 320 to the first water outlet 312, causing the first opening 321 to separate from the first water inlet 311.

[0068] Specifically, the first valve core 320 and the first valve body 310 can be fixedly connected by screwing, clamping or other detachable ways, which are not limited.

[0069] In some embodiments, Figure 7 It is shown Figure 3 The structure of the water outlet valve and the water outlet pipe is shown in FIG. 4, please refer to Figure 7 The water outlet valve 400 includes a second valve body 410 and a second valve core 420 arranged in the second valve body, the second valve body has a second water inlet 411 and a second water outlet 412, the second water inlet 411 is in communication with the shell 520, and the second valve core 420 can communicate or cut off the second water inlet 411 and the second water outlet 412 under the condition that the piston 530 moves.

[0070] The second valve core 420 can be made of rubber, silica gel or other elastic materials, and the second water inlet 411 and the second water outlet 412 can be arranged oppositely. During the movement of the piston 530 in the shell 520, the air pressure in the shell 520 will change, since the second valve core 420 is movably arranged in the second valve body 410, and the second water inlet 411 is in communication with the shell 520, thus the air pressure in the second valve body 410 will also change, causing the second valve core 420 to deform, thereby communicating or cutting off the second water inlet 411 and the second water outlet 412.

[0071] In some embodiments, the second valve core 420 has a third opening 421 and a fourth opening 422 in communication with the third opening 421, the third opening 421 is in communication with the second water inlet 411, and the fourth opening 422 can be opened or closed under the condition that the piston 530 moves.

[0072] The third opening 421 is arranged close to the second water inlet 411, and the fourth opening 422 is arranged close to the second water outlet 412. The fourth opening 422 can have a gap with the second water outlet 412 or can be attached to the second water outlet 412, which is not limited. Since the second water inlet 411 is communicated with the shell 520, when the piston 530 moves in the first direction, the volume of the water cavity 521 increases, the pressure decreases, and the pressure in the second valve core 420 also decreases, which is less than the pressure in the second valve body 410. Therefore, the pressure inside the second valve core 420 is less than the pressure outside, and the second valve core 420 is pressed inward under the pressure of the outside, so that the fourth opening 422 is closed, and the second valve core 420 cuts off the second water inlet 411 and the second water outlet 412. When the piston 530 moves in the second direction, the volume of the water cavity 521 decreases, the pressure increases, and the pressure in the second valve core 420 also increases, which is greater than the pressure in the second valve body 410. Therefore, the pressure inside the second valve core 420 is greater than the pressure outside, and the second valve core 420 is expanded outward under the pressure of the inside, so that the fourth opening 422 is opened, and the second valve core 420 communicates the second water inlet 411 and the second water outlet 412.

[0073] Specifically, Figure 8 It is shown Figure 7 The structure of the second valve core in the second valve is shown in FIG. 4, please refer to Figure 7 and Figure 8 The second valve core 420 has a second channel 423 communicated with the third opening 421 and the fourth opening 422, and the second channel 423 has two second side walls 424 arranged oppositely, which enclose the fourth opening 422. When the second valve core 420 is pressed inward under the pressure of the outside, the two second side walls 424 move oppositely and abut tightly, so that the fourth opening 422 is closed. When the second valve core 420 is expanded outward under the pressure of the outside, the two second side walls 424 are separated, so that the fourth opening 422 is opened.

[0074] It should be noted that the size of the third opening 421 is much larger than the size of the fourth opening 422. When the second valve core 420 is pressed inward under the pressure of the outside, the fourth opening 422 is closed under the action of the pressure difference, and at the same time, the third opening 421 also deforms to a certain extent, but the deformation is not enough to completely close the third opening 421, so as not to affect the communication between the third opening 421 and the second water inlet 411.

[0075] In some embodiments, the second valve core 420 is fixedly connected with the second valve body 410.

[0076] Since the second water inlet 411 is in communication with the shell 520, i.e. in the direction of the water inlet pipe 100, the second water inlet 411 is closer to the shell 520 than the second water outlet 412, so when the piston 530 moves in the first direction, the volume of the water cavity 521 increases, the pressure decreases, and the pressure of the second water inlet 411 will decrease first than the second water outlet 412, i.e. the pressure of the second water outlet 412 is greater than the pressure of the second water inlet 411. Since air flows from a high air pressure place to a low air pressure place, the second valve core 420 will have a tendency to move towards the second water outlet 412 under the pressure difference, causing the third opening 421 to separate from the second water inlet 411. Therefore, fixing the second valve core 420 and the second valve body 410 can to some extent avoid the second valve core 420 moving towards the second water outlet 412, causing the third opening 421 to separate from the second water inlet 411.

[0077] Specifically, the second valve core 420 and the second valve body 410 can be fixedly connected by screwing, clamping or other detachable methods, which are not limited.

[0078] In some embodiments, referring to Figures 5-7 , the water inlet valve 300 includes a first valve body 310 and a first valve core 320 arranged in the first valve body 310, the first valve body 310 has a first water inlet 311 and a first water outlet 312, and the first water outlet 312 is in communication with the shell 520; the water outlet valve 400 includes a second valve body and a second valve core 420 arranged in the second valve body, the second valve body has a second water inlet 411 and a second water outlet 412, and the second water inlet 411 is in communication with the shell 520; wherein the movement of the piston 530 can make the first valve core 320 communicate the first water inlet 311 and the first water outlet 312, and the second valve core 420 cut off the second water inlet 411 and the second water outlet 412; or the first valve core 320 cuts off the first water inlet 311 and the first water outlet 312, and the second valve core 420 communicates the second water inlet 411 and the second water outlet 412.

[0079] During the movement of the piston 530 in the shell 520, the air pressure in the shell 520 changes, and since the first water outlet 312 and the second water inlet 411 are in communication with the shell 520, the air pressure in the first valve body 310 and the second valve body 410 also changes, so that the first valve core 320 and the second valve core 420 are deformed under the action of the air pressure, and the deformation directions of the first valve core 320 and the second valve core 420 are opposite, that is, when the first valve core 320 communicates the first water inlet 311 and the first water outlet 312, the second valve core 420 cuts off the second water inlet 411 and the second water outlet 412; or when the first valve core 320 cuts off the first water inlet 311 and the first water outlet 312, the second valve core 420 communicates the second water inlet 411 and the second water outlet 412. Therefore, only the movement of the piston 530 needs to be controlled to simultaneously realize the opening and closing of the water inlet valve 300 and the water outlet valve 400, without the need to separately control the opening and closing of the water inlet valve 300 and the water outlet valve 400, thereby reducing the steps of water pumping and draining and improving the water pumping and draining efficiency.

[0080] In some embodiments, Figure 9 It is shown Figure 4 A sectional view of another perspective of the driving mechanism in the middle, Figure 10 It is shown Figure 9 An assembly schematic diagram of the driving assembly and the piston in the middle, please refer to Figure 9 and Figure 10 The driving assembly 510 includes a driver 511 and a transmission assembly 512, the driver 511 is in transmission connection with the transmission assembly 512, the transmission assembly 512 is in transmission connection with the piston 530, and the driver 511 can drive the transmission assembly 512 to rotate to drive the piston 530 to move.

[0081] The transmission assembly 512 can drive the piston 530 to move in the shell 520 along a first direction by rotating, when the transmission assembly 512 rotates by half a circle, the transmission assembly 512 continues to rotate to drive the piston 530 to move in the shell 520 along a second direction, when the transmission assembly 512 rotates by half a circle, the transmission assembly 512 continues to rotate to drive the piston 530 to move in the shell 520 along the first direction, and so on, that is, when the transmission assembly 512 rotates by a whole circle, the piston 530 completes a straight reciprocating motion in the shell 520. Therefore, the transmission assembly 512 rotates by half a circle, and the movement direction of the piston 530 can be switched between the first direction and the second direction, so that the driving mechanism 500 can be switched between water pumping and water draining. The transmission assembly 512 can rotate clockwise or counterclockwise, which is not limited.

[0082] The transmission assembly 512 comprises a transmission member 512a, a rotating member 512b and a connecting rod member 512c. The transmission member 512a is in transmission connection with the driver 511. The transmission member 512a is in transmission connection with the rotating member 512b. The connecting rod member 512c is in transmission connection with the rotating member 512b. Part of the connecting rod member 512c is arranged in the rodless cavity and is in transmission connection with the piston 530. The driver 511 can drive the transmission member 512a to rotate, so that the rotating member 512b can rotate relative to the transmission member 512a, thereby driving the piston 530 to move.

[0083] Specifically, the driver 511 can be a motor. The transmission member 512a is a worm gear. The rotating member 512b is a planetary gear train. The worm gear is coaxially connected with the planetary gear train. That is, the motor drives the worm gear to rotate, so that the worm gear rotates, and the planetary gear train rotates and drives the connecting rod member 512c to make a linear reciprocating motion, thereby driving the piston 530 to make a linear reciprocating motion in the housing 520.

[0084] In some embodiments, Figure 11 It is shown Figure 9 that the piston cooperates with the housing, Figure 12 It is shown Figure 11 that the piston cooperates with the sealing structure. Please refer to Figure 11 and Figure 12 The waterway system 10 further comprises a first sealing member 600 and a second sealing member 700. The first sealing member 600 and the second sealing member 700 are arranged between the piston 530 and the housing 520 and are arranged in sequence along the movement direction of the piston 530.

[0085] The first sealing member 600 and the second sealing member 700 move with the piston 530 to form dynamic sealing. The first sealing member 600 and the second sealing member 700 can be made of flexible materials such as rubber and silicone, and have elasticity and can adaptively deform to achieve better sealing effect. The first sealing member 600 and the second sealing member 700 can be annular structures and are sleeved on the piston 530. The first sealing member 600 and the second sealing member 700 form two-stage sealing between the piston 530 and the housing 520. Under the double sealing of the first sealing member 600 and the second sealing member 700, the water entering the rodless cavity can be greatly reduced, thereby ensuring the smoothness of the movement of the piston and the water pumping and draining effect.

[0086] In some embodiments, the first sealing member 600 is arranged close to the water cavity 521, and the second sealing member 700 is arranged close to the rodless cavity 522.

[0087] That is, the first seal 600 implements a primary sealing function, and the second seal 700 implements a final sealing function. During the movement of the piston 530 for water pumping and draining, the first seal 600 forms a first sealing for water and impurities, and can block most of the water and impurities in the water cavity 521. A small amount of water and impurities can enter the first seal 600, and the second seal 700 forms a second sealing for the water and impurities, thereby reducing the impurities entering the water-free cavity 522 to the greatest extent, and ensuring the smooth movement of the piston 530 and the water pumping and draining effect.

[0088] Of course, in other embodiments, the second seal 700 can be arranged close to the water cavity 521, and the first seal 600 can be arranged close to the water-free cavity 522, which is not limited.

[0089] In some embodiments, Figure 13 It is shown Figure 11 that the first seal is arranged in the water cavity 521, please refer to Figure 12 and Figure 13 The first seal 600 includes a first seal body 610 and a protruding portion 620 protruding from the first seal body 610. The first seal body 610 is sleeved on the piston 530, and the protruding portion 620 can be in contact with the shell 520.

[0090] After the waterway system 10 is used for a long time, impurities in the water can also accumulate on the side wall of the shell 520, affecting the movement of the piston 530. Since the protruding portion 620 can be in contact with the shell 520, the protruding portion 620 and the shell 520 can be rubbed against each other during the movement of the piston 530, so that the protruding portion 620 can scrape off a large amount of dirt on the side wall of the shell 520, so that the side wall of the shell 520 can be kept clean, the impurities entering the second seal 700 can be reduced, the damage of the second seal 700 caused by particulate matter in the impurities can be effectively improved, and the sealing effect of the second seal 700 can be ensured.

[0091] In some embodiments, the protruding portion 620 has a plurality of protruding portions 620, and the plurality of protruding portions 620 are arranged at intervals along the movement direction of the piston 530.

[0092] Since the protrusions 620 are protruded from the first sealing body 610, the protrusions 620 can be in contact with the shell 520, and then a gap is formed between the part of the first sealing body 610 and the shell 520. Since the protrusions 620 are elastic, when the liquid pressure is large, the protrusions 620 can be separated from the shell 520 under the impact of the water flow, so that the water enters the gap between the first sealing member 600 and the second sealing member 700, thereby forming a pressure difference at both ends of the first sealing member 600. The larger the pressure difference is, the greater the deformation of the first sealing member 600 is, which leads to more water entering the second sealing member 700, thereby affecting the sealing effect.

[0093] Since the protrusions 620 are arranged at intervals, that is, there is a gap between the two adjacent protrusions 620, and a plurality of chambers 630 are formed between the protrusions 620 and the shell 520. When the piston 530 moves in the direction from the water chamber 521 to the waterless chamber 522, the first protrusion 620 is directly in contact with the water in the water chamber 521, and the fluid impact on the first protrusion 620 is the largest, so that the pressure difference formed on both sides of the first protrusion 620 is the largest, and the deformation of the first protrusion 620 is also the largest, that is, the gap between the first protrusion 620 and the shell 520 is the largest, so that the amount of water entering the first chamber 630 through the gap is the largest. However, since the amount of water entering the chamber 630 is much smaller than the amount of water in the water chamber 521, the fluid impact on the second protrusion 620 is smaller, and the pressure difference formed on both sides of the second protrusion 620 is much smaller than the pressure difference formed on both sides of the first protrusion 620, and the deformation of the second protrusion 620 is also smaller than the deformation of the first protrusion 620, so that the amount of water entering the second chamber 630 is smaller, and the deformation of the third protrusion 620 is smaller than the deformation of the second protrusion 620, and so on. It can be clearly known that the pressure difference on both sides of the last protrusion 620, that is, the protrusion 620 closest to the second sealing member 700, is the smallest, the deformation of the last protrusion 620 is the smallest, and the sealing effect of the last protrusion 620 is the best, so that the amount of water entering the second sealing member 700 is smaller, the fluid impact on the second sealing member 700 is reduced, and the sealing effect of the second sealing member 700 is ensured.

[0094] In addition, the contact area between the piston 530 and the shell 520 can be reduced by the plurality of protrusions 620 arranged at intervals and in contact with the shell 520, so that the frictional resistance between the piston 530 and the shell 520 during the movement of the piston 530 is reduced, and the movement of the piston 530 is smoother.

[0095] In some embodiments, Figure 14 The structure of the first sealing member is shown Figure 13 The structure of the first sealing member is shown Figure 15 The structure of the first sealing member is shown Figure 14 The structure of the first sealing member is shown Figures 13-15The first sealing body 610 comprises a first sealing part 611 and a second sealing part 612. The first sealing part 611 is annularly arranged on the circumferential side of the piston 530. The second sealing part 612 is arranged on the end of the piston 530. The protruding part 620 is arranged on the first sealing part 611.

[0096] Since the first sealing part 611 is annularly arranged on the circumferential side of the piston 530 and the second sealing part 612 is arranged on the end of the piston 530, that is, the first sealing body 610 wraps the circumferential side and the end of the piston 530, the part of the piston 530 exposed to the water is reduced, so that the situation that impurities in the water accumulate on the piston 530 and increase the movement resistance of the piston 530 can be improved, and to some extent, the damage of particulate matters in the impurities to the piston 530 is avoided, and the service life of the piston 530 is affected.

[0097] In some embodiments, the first sealing part 611 and the second sealing part 612 can be integrally arranged to enhance the structural strength of the first sealing body 610. Of course, in other embodiments, the first sealing part 611 and the second sealing part 612 can be separately arranged, which is not specifically limited.

[0098] In some embodiments, the second sealing part 612 is provided with a guide surface 612a which is arranged obliquely away from the piston 530.

[0099] The guide surface 612a is arranged obliquely towards the second sealing part 612, and the guide surface 612a is annularly arranged on the second sealing part 612. During the movement of the piston 530, the guide surface 612a can guide the water to some extent, so that the movement resistance of the piston 530 can be reduced, the smoothness of the movement of the piston 530 can be improved, and the water pumping and draining effect can be ensured.

[0100] Specifically, the guide surface 612a can be a conical surface, that is, the circumferential surface of the second sealing part 612 away from the piston 530 is an inclined surface, so that the movement resistance of the piston 530 can be further reduced, the smoothness of the movement of the piston 530 can be improved, and the water pumping and draining effect can be ensured.

[0101] In some embodiments, please refer to Figure 12 , the first sealing body 610 and the piston 530, one of which has a clamping part 613, and the other has a clamping groove 531, and the clamping part 613 is clamped in the clamping groove 531.

[0102] The first sealing body 610 may have the engaging portion 613 and the piston 530 may have the engaging groove 531, or the first sealing body 610 may have the engaging groove 531 and the piston 530 may have the engaging portion 613, without limitation. The provision of the engaging portion 613 and the engaging groove 531 can position the first sealing member 600, enhance the installation stability of the first sealing member 600 on the piston 530, reduce the possibility of the first sealing member 600 falling off the piston 530, and ensure a good sealing effect.

[0103] The clamping portion 613 can be made of elastic material and has an interference fit with the clamping groove 531, which can improve the fixing effect between the clamping portion 613 and the clamping groove 531, thereby further improving the installation stability of the first seal 600 on the piston 530 and ensuring the sealing effect.

[0104] The above describes the specific structure of the first sealing member 600 , and the following will describe the specific structure of the second sealing member 700 in detail.

[0105] In some embodiments, Figure 16 Shown Figure 11 The structural diagram of the second seal, Figure 17 Shown Figure 16 A schematic diagram of the structure of the second seal from another perspective, Figure 18 Shown Figure 17 For a cross-sectional view of the second seal, see Figures 16-18 The second seal 700 has a first sealing surface 711 and a first guide surface 721. Part of the first sealing surface 711 abuts against the piston 530. The first guide surface 721 is arranged on the side of the second seal 700 close to the first seal 600. In the direction from the second seal 700 toward the first seal 600, the first guide surface 721 is inclined toward the first sealing surface 711.

[0106] When no water flows in, part of the first sealing surface 711 abuts against the piston 530, that is, there is a gap between part of the first sealing surface 711 and the piston 530. Since the first guide surface 721 is inclined toward the first sealing surface 711, when water flows into the second sealing member 700, the first guide surface 721 will be subjected to pressure. Since the second sealing member 700 is elastic, under the action of pressure, the remaining part of the first sealing surface 711 will also deform to abut against the piston 530, thereby increasing the sealing area between the first sealing surface 711 and the piston 530. Moreover, the greater the impact of the water flow, the greater the pressure on the first guide surface 721, the tighter the abutment between the first sealing surface 711 and the piston 530, the better the sealing effect between the second sealing member 700 and the piston 530, and the less water and impurities enter the waterless chamber 522, thereby ensuring the smooth movement of the piston 530 and the pumping and drainage effects.

[0107] In some embodiments, the first sealing surface 711 is arc-shaped, and the inner arc of the first sealing surface 711 faces the piston 530.

[0108] That is, in the absence of water flow, the two ends of the first sealing surface 711 abut against the piston 530, and the middle arch portion has a gap with the piston 530. When the first flow guide surface 721 is subjected to water flow pressure, the first sealing surface 711 elastically deforms under the pressure, so that the middle portion also abuts against the piston 530, increasing the sealing area of the first sealing surface 711 and the piston 530.

[0109] In some embodiments, the second sealing member 700 also has a second sealing surface 731 and a second flow guide surface 722. The second sealing surface 731 is partially in abutment with the shell 520, and the second flow guide surface 722 is arranged on the side of the second sealing member 700 close to the first sealing member 600, and is arranged to be inclined toward the second sealing surface 731 in the direction of the second sealing member 700 toward the first sealing member 600.

[0110] In the absence of water flow, the second sealing surface 731 is partially in abutment with the shell 520, that is, the second sealing surface 731 has a gap with the shell 520. Since the second flow guide surface 722 is arranged to be inclined toward the second sealing surface 731, when water flow enters the second sealing member 700, the second flow guide surface 722 will be subjected to pressure. Since the second sealing member 700 is elastic, the rest of the second sealing surface 731 will also deform to abut against the shell 520 under the pressure, increasing the sealing area of the second sealing surface 731 and the shell 520. The greater the water flow impact, the greater the pressure on the second flow guide surface 722, the tighter the abutment of the second sealing surface 731 and the shell 520, the better the sealing effect between the second sealing member 700 and the shell 520, and the less water and impurities entering the water-free cavity 522, ensuring smooth movement of the piston 530 and the water pumping and draining effect.

[0111] In some embodiments, the second sealing surface 731 is arc-shaped, and the inner arc of the second sealing surface 731 faces the shell 520.

[0112] That is, in the absence of water flow, the two ends of the second sealing surface 731 abut against the shell 520, and the middle arch portion has a gap with the shell 520. When the second flow guide surface 722 is subjected to water flow pressure, the second sealing surface 731 elastically deforms under the pressure, so that the middle portion also abuts against the shell 520, increasing the sealing area of the second sealing surface 731 and the shell 520.

[0113] It should be noted that the side of the second sealing member 700 away from the first sealing member 600 can also be provided with the first flow guide surface 721 and the second flow guide surface 722, so that the second sealing member 700 is a symmetrical structure, so that when the second sealing member 700 is installed, it does not matter which side faces the first sealing member 600, thereby improving the installation convenience of the second sealing member 700.

[0114] In some embodiments, the second sealing member 700 has a flow guide groove 740 with a first flow guide surface 721 and a second flow guide surface 722, and in the direction in which the second sealing member 700 faces the first sealing member 600, the first flow guide surface 721 is inclined away from the second flow guide surface 722, and the second flow guide surface 722 is inclined away from the first flow guide surface 721.

[0115] Since the first flow guide surface 721 is inclined away from the second flow guide surface 722, and the second flow guide surface 722 is inclined away from the first flow guide surface 721, when the water flow enters the flow guide groove 740, both the first flow guide surface 721 and the second flow guide surface 722 will be subjected to pressure, and since the second sealing member 700 is elastic, the second sealing member 700 will be pressed against the piston 530 and the housing 520, respectively, under the action of the pressure, thereby improving the sealing effect.

[0116] In some embodiments, referring to Figures 9-11 , the second sealing member 700 includes a third sealing portion 710, a fourth sealing portion 720, and a fifth sealing portion 730, the fourth sealing portion 720 is connected between the third sealing portion 710 and the fifth sealing portion 730, the third sealing portion 710 abuts against the piston 530, and the fifth sealing portion 730 abuts against the housing 520 to form a seal between the piston 530 and the housing 520.

[0117] The third sealing portion 710, the fourth sealing portion 720, and the fifth sealing portion 730 can all be annular structures, the third sealing portion 710 is annularly arranged on the periphery of the piston 530, the fifth sealing portion 730 is annularly arranged on the periphery of the housing 520, and the fourth sealing portion 720 is connected between the third sealing portion 710 and the fifth sealing portion 730. The third sealing portion 710 and the fifth sealing portion 730 need to abut against the piston 530 and the housing 520, respectively, to form a sealing surface, and need to ensure a certain sealing area, so the cross-sectional size of the third sealing portion 710 and the fifth sealing portion 730 can be larger than the cross-sectional size of the fourth sealing portion 720.

[0118] Specifically, the first sealing surface 711 and the first flow guide surface 721 are arranged on the third sealing part 710, and the second sealing surface 731 and the second flow guide surface 722 are arranged on the fifth sealing part 730. The third sealing part 710, the fourth sealing part 720 and the fifth sealing part 730 enclose the flow guide groove 740. Since the first flow guide surface 721 is inclined away from the second flow guide surface 722, and the second flow guide surface 722 is inclined away from the first flow guide surface 721, when the water flow enters the flow guide groove 740, the first flow guide surface 721 and the second flow guide surface 722 will be subjected to pressure. Since the second sealing part 700 is elastic, the part of the third sealing part 710 and the second sealing part 612 close to the first sealing part 600 will move away from each other under the action of pressure, so that the first sealing part 600 and the second sealing surface 731 abut against the piston 530 and the shell 520 more tightly, thereby improving the sealing effect.

[0119] In some embodiments, referring to Figure 12 , the peripheral side of the piston 530 is provided with a mounting groove 532, and the second sealing part 700 is arranged in the mounting groove 532, so that the second sealing part 700 is more stable on the piston 530.

[0120] In some embodiments, Figure 19 The structure of the piston is shown in Figure 11 , referring to Figure 19 , the peripheral side of the piston 530 is sequentially and spacedly provided with a top plate 533, a partition plate 534 and a bottom plate 535. The mounting groove 532 is formed between the top plate 533 and the partition plate 534 for mounting the sealing part. The partition plate 534 and the bottom plate 535 form a clamping groove 531 for clamping with the clamping part 613 on the first sealing body 610. Of course, in order not to affect the movement of the piston 530, the top plate 533, the partition plate 534 and the bottom plate 535 have a certain gap with the shell 520, and the cross-sectional length of the bottom plate 535 is shorter than that of the partition plate 534, so that a sufficient gap can be formed between the bottom plate 535 and the shell 520 to mount the first sealing body 610.

[0121] In some embodiments, the piston 530 includes a first piston segment 536 and a second piston segment 537, and the first piston segment 536 and the second piston segment 537 are detachably connected. The first sealing part 600 is arranged on the first piston segment 536, and the second sealing part 700 is arranged on the second piston segment 537.

[0122] In assembling the piston 530, the first seal 600 can be installed on the first piston segment 536, the second seal 700 can be installed on the second piston segment 537, and then the first piston segment 536 and the second piston segment 537 can be connected together, so that the installation of the first seal 600 and the second seal 700 is facilitated. The first piston segment 536 and the second piston segment 537 can be connected by screwing, clamping or the like, and are not limited in this regard.
