Description

Technical Field

[0001] This application belongs to the technical field of fluid transportation, and particularly relates to a pumping system and a cleaning device. Background Art

[0002] A pumping system is used to transport fluids, such as gases, liquids, or gas-liquid mixtures, etc., to a preset position, and it is widely used in daily life and industrial production.

[0003] Currently, traditional pumping systems generally include a housing, a rotary drive, a transmission device, an extrusion member, and a fluid delivery pipe. Specifically, the fluid delivery pipe is generally an elastic hose. The rotary drive is arranged in the housing, the transmission device is arranged in the inner cavity of the housing and is in transmission connection with the rotary drive, and the extrusion member is eccentrically arranged on the transmission device and is used to extrude the fluid delivery pipe. This design enables the pumping system to only pump a single type of fluid, and the flow rate of the fluid is single. When it comes to the transportation of at least two different types of fluids, or at least two different flow rates of fluids, it is often necessary to correspondingly set at least two pumping systems, so that each pumping system transports different types of fluids or fluids with different flow rates respectively, which results in a relatively high cost for fluid transportation. Summary of the Utility Model

[0004] The purpose of the embodiments of this application is to provide a pumping system and a cleaning device, which can solve the problem of relatively high cost for fluid transportation in related technologies.

[0005] In a first aspect, the embodiments of this application provide a pumping system, including: a housing, a rotary drive, at least two transmission devices, at least two extrusion members, and at least two fluid delivery pipes;

[0006] The rotary drive is arranged in the housing, and each of the transmission devices is arranged in the inner cavity of the housing and is in transmission connection with the same rotary drive;

[0007] Each of the transmission devices is eccentrically provided with the extrusion member, the fluid delivery pipe is configured as an elastic hose, the fluid delivery pipes correspond to the transmission devices one by one, each fluid delivery pipe bypasses the extrusion member on the corresponding transmission device, and can be extruded by at least one of the extrusion members.

[0008] In a second aspect, the embodiments of this application also provide a cleaning device, which includes the pumping system described above.

[0009] In the embodiment of the present application, the pumping system includes a rotary drive and at least two transmission devices, and each transmission device is in transmission connection with the rotary drive. In other words, the various transmission devices of the pumping system provided in the embodiment of the present application share a rotary drive. During specific use, when the rotary drive rotates, each transmission device and each squeezing member rotate accordingly. During the rotation of each squeezing member, it alternately squeezes and releases the corresponding fluid delivery pipe. When the squeezing member squeezes the corresponding fluid delivery pipe, it can push the fluid in the corresponding fluid delivery pipe to move along the extension direction of the fluid delivery pipe towards one end of the extension direction of the fluid delivery pipe. When the squeezing member releases the corresponding fluid delivery pipe, the previously squeezed part of the fluid delivery pipe automatically resets, and at the same time, a negative pressure is generated in the fluid delivery pipe. Under the action of this negative pressure, the other end in the extension direction of the fluid delivery pipe can suck the external fluid into the fluid delivery pipe. Thus, as the rotary drive rotates, each fluid delivery pipe can convey fluid. On this basis, by enabling each fluid delivery pipe to suck different types of fluid respectively, the pumping system provided in the embodiment of the present application can convey at least two different types of fluid. By controlling the transmission ratio between each transmission device and the rotary drive, the pumping system provided in the embodiment of the present application can convey at least two different flow rates of fluid.

[0010] Compared with the solution of setting at least two pumping systems in the background art to pump different types of fluid or different flow rates of fluid respectively, in the solution adopted in the embodiment of the present application, the various transmission devices share a rotary drive, and in the solution adopted in the embodiment of the present application, the various transmission devices are arranged in the inner cavity of the same housing. Therefore, in the solution adopted in the embodiment of the present application, the number of rotary drives and housings involved is less. Since the processing of each rotary drive and each housing requires a certain amount of material, the material cost of the solution adopted in the embodiment of the present application is lower. Moreover, the solution mentioned in the background art needs to control at least two rotary drives to work, while the solution adopted in the embodiment of the present application only needs to control one rotary drive to work. In this way, the control system required by the solution adopted in the embodiment of the present application is simpler. Thus, in the solution adopted in the embodiment of the present application, a circuit board with a smaller area can be set, and fewer control components can be arranged to achieve the overall control of the pumping system. Therefore, the control cost of the solution adopted in the embodiment of the present application is also lower, and further, the solution adopted in the embodiment of the present application makes the conveying cost of the fluid lower. In addition, each rotary drive and each housing need to occupy a certain space. In the solution adopted in the embodiment of the present application, the number of rotary drives and housings involved is less, so the pumping system adopted in the embodiment of the present application occupies less space.

[0028] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same type, and do not limit the number of objects. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0030] Next, in conjunction with the accompanying drawings, the pumping system and cleaning equipment provided in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0031] Please refer to Figures 1 to 10 As shown, in the embodiments of the present application, a pumping system is provided, including: a housing 100, a rotary drive member 200, at least two transmission devices 300, at least two extrusion members 410, and at least two fluid delivery pipes 510. The specific numbers of the transmission devices 300, the extrusion members 410, and the fluid delivery pipes 510 are all determined according to actual needs.

[0032] The rotary drive member 200 is disposed in the housing 100. Each transmission device 300 is disposed in the inner cavity of the housing 100 and is in transmission connection with the same rotary drive member 200. The rotary drive member 200 is, for example, a motor or a motor, and the rotary drive member 200 is, for example, disposed outside the housing 100.

[0033] An extrusion member 410 is eccentrically provided on each transmission device 300. For example, the axis of each extrusion member 410 is parallel to the axis of the corresponding transmission device 300, and each transmission device 300 rotates around its own axis, for example. The fluid delivery pipe 510 is configured as an elastic hose, and the fluid delivery pipe 510 is used to deliver fluid, and the fluid is, for example, gas, liquid, or a gas-liquid mixture. The fluid delivery pipes 510 correspond to the transmission devices 300 one by one. Each fluid delivery pipe 510 bypasses the extrusion member 410 on the corresponding transmission device 300 and can be extruded by at least one extrusion member 410, that is, the same fluid delivery pipe 510 can be simultaneously extruded by at least two extrusion members 410 or can be extruded by only one extrusion member 410.

[0034] In an embodiment of the present application, the pumping system includes a rotary driving member 200 and at least two transmission devices 300, and each transmission device 300 is in transmission connection with the rotary driving member 200. In other words, the various transmission devices 300 of the pumping system provided in the embodiment of the present application share a rotary driving member 200.

[0035] During the specific use process, the rotary driving member 200 rotates, and each transmission device 300 and each squeezing member 410 rotate accordingly. During the rotation of each squeezing member 410, it alternately squeezes and releases the corresponding fluid delivery pipe 510. Specifically, for example, when the squeezing member 410 rotates to the first position, the squeezing member 410 squeezes the first part of the fluid delivery pipe 510. After that, when the squeezing member 410 rotates to the second position, the squeezing member 410 squeezes the second part of the fluid delivery pipe 510 and releases the first part of the fluid delivery pipe 510. When the squeezing member 410 squeezes the corresponding fluid delivery pipe 510, it can push the fluid in the corresponding fluid delivery pipe 510 to move along the extension direction of the fluid delivery pipe 510 towards one end of the extension direction of the fluid delivery pipe 510. When the squeezing member 410 releases the corresponding fluid delivery pipe 510, the previously squeezed part of the fluid delivery pipe 510 automatically resets, and at the same time, a negative pressure is generated in the fluid delivery pipe 510. Under the action of this negative pressure, the other end in the extension direction of the fluid delivery pipe 510 can suck the external fluid into the fluid delivery pipe 510. Thus, as the rotary driving member 200 rotates, each fluid delivery pipe 510 can convey fluid. On this basis, by making each fluid delivery pipe 510 suck different types of fluid respectively, the pumping system provided in the embodiment of the present application can convey at least two different types of fluid. By controlling the transmission ratio between each transmission device 300 and the rotary driving member 200, the pumping system provided in the embodiment of the present application can convey at least two different flow rates of fluid. By making each fluid delivery pipe 510 suck different types of fluid respectively and at the same time controlling the transmission ratio between each transmission device 300 and the rotary driving member 200, the pumping system provided in the embodiment of the present application can also convey at least two types of fluid with different flow rates.

[0036] Compared with the solution in the background art where at least two pumping systems are provided to pump different types of fluids or fluids with different flow rates respectively, in the solution adopted in the embodiments of the present application, each transmission device 300 shares a single rotary drive member 200, and each transmission device 300 in the solution adopted in the embodiments of the present application is arranged in the inner cavity of the same housing 100. Therefore, the number of rotary drive members 200 and housings 100 involved in the solution adopted in the embodiments of the present application is less. Since the processing of each rotary drive member 200 and each housing 100 requires a certain amount of materials, the material cost of the solution adopted in the embodiments of the present application is lower. Moreover, the solution mentioned in the background art needs to control at least two rotary drive members 200 to work, while only one rotary drive member 200 needs to be controlled in the solution adopted in the embodiments of the present application. In this way, the control system required for the solution adopted in the embodiments of the present application is simpler. Thus, a circuit board with a smaller area can be set in the solution adopted in the embodiments of the present application, and fewer control components can be arranged to achieve the overall control of the pumping system. Therefore, the control cost of the solution adopted in the embodiments of the present application is also lower, and further, the solution adopted in the embodiments of the present application results in a lower fluid transportation cost. In addition, each rotary drive member 200 and each housing 100 need to occupy a certain space. Since the number of rotary drive members 200 and housings 100 involved in the solution adopted in the embodiments of the present application is less, the pumping system adopted in the embodiments of the present application occupies a smaller space.

[0037] It should be noted that in the embodiments of the present application, there are no restrictions on the area of the cross-section of each fluid delivery pipe 510 in the direction perpendicular to its own extension direction, the material of each fluid delivery pipe 510, and the type and flow rate of the fluid transported by each fluid delivery pipe 510. Each fluid delivery pipe 510 can be designed separately according to actual needs. Additionally, during the specific use process, when the flow rates required for at least two different types of fluids are the same and the fluids can be mixed and transported, the at least two different types of fluids can be transported simultaneously using the same fluid delivery pipe 510.

[0038] In another embodiment, referring to Figure 3 、 Figure 8 and Figure 9 as shown, the rotary drive member 200 is in transmission connection with each transmission device 300 in sequence. In other words, each transmission device 300 is arranged in sequence along the power transmission direction of the rotary drive member 200 and is in transmission connection in sequence. The one of each transmission device 300 closest to the rotary drive member 200 is in transmission connection with the rotary drive member 200.

[0039] In this embodiment, the transmission devices 300 are arranged in sequence along the power transmission direction of the rotary drive member 200. In this way, each transmission device 300 basically does not additionally occupy the space in other directions, so that the overall pumping system is relatively compact and occupies a small space. In addition, by sequentially drivingly connecting the rotary drive member 200 with each transmission device 300, without additionally adding other transmission structures, the transmission ratio between each transmission device 300 and the rotary drive member 200 can be increased or decreased sequentially along the power transmission direction of the rotary drive member 200, so that the overall structure of the pumping system is relatively simple and the cost is low.

[0040] As a specific implementation manner, along the power transmission direction of the rotary drive member 200, the transmission ratio between the rotary drive member 200 and each transmission device 300 decreases sequentially, for example.

[0041] In other alternative embodiments, each transmission device 300 can also be drivingly connected to the rotary drive member 200 separately through the corresponding transmission structure thereof.

[0042] In a further embodiment, the transmission device 300 includes a planetary transmission mechanism. The sun gear 320 of the one closest to the rotary drive member 200 in each planetary transmission mechanism is drivingly connected to the rotary drive member 200. The planet carrier 310 of the one closest to the rotary drive member 200 in any two adjacent planetary transmission mechanisms is drivingly connected to the sun gear 320 of the other. And the ring gear 340 of each planetary transmission mechanism is fixedly connected to the housing 100. Each extrusion member 410 is arranged on the planet carrier 310 of the corresponding planetary transmission mechanism. The planetary transmission mechanism has the characteristic of being structurally compact. Thus, the transmission device 300 including the planetary transmission mechanism can make the structure of the transmission device 300 relatively compact, and further make the compactness of the pumping system better.

[0043] As a specific implementation manner, referring to Figure 3 as shown, the sun gear 320 of the one closest to the rotary drive member 200 in each transmission device 300 is drivingly connected to the drive shaft 210 of the rotary drive member 200. And the number of the transmission devices 300 is two, for example. For the convenience of distinction, the one closest to the rotary drive member 200 among the two transmission devices 300 is defined as the first transmission device, and the other is defined as the second transmission device.

[0044] During the specific use process, when the rotation driving member 200 works, the driving shaft 210 rotates, driving the sun gear 320 of the first transmission device to rotate. Then, the sun gear 320 of the first transmission device drives the planet carrier 310 of the first transmission device to rotate through the planet gears 330 of the first transmission device, thereby driving the extrusion member 410 on the planet carrier 310 to rotate around the axis of the planet carrier 310. While the planet carrier 310 rotates, it drives the sun gear 320 of the second transmission device to rotate, thereby transmitting power to the second transmission device.

[0045] In other alternative embodiments, the transmission device 300 may further include at least two gears that are sequentially connected in transmission.

[0046] In a further embodiment, referring to Figure 8 As shown, each fluid delivery pipe 510 is disposed on the side of the corresponding transmission device 300 away from the rotation driving member 200, and each extrusion member 410 is disposed on the side of the corresponding transmission device 300 away from the rotation driving member 200. With such a setting, the fluid delivery pipes 510 and the extrusion members 410 are concentrated in the power transmission direction of the rotation driving member 200. In this way, the compactness of the pumping system can be further improved.

[0047] In other alternative embodiments, each fluid delivery pipe 510 can also be staggered from the corresponding transmission device 300 in the power transmission direction of the rotation driving member 200, and at the same time, each extrusion member 410 can also be staggered from the corresponding transmission device 300 in the power transmission direction of the rotation driving member 200.

[0048] In a further embodiment, referring to Figure 3 、 Figure 8 And Figure 9 As shown, the pumping system further includes at least two mounting shafts 420 and at least two stoppers 600. The mounting shafts 420 correspond to the extrusion members 410 one by one. Each extrusion member 410 is rotatably sleeved on the corresponding mounting shaft 420. Each mounting shaft 420 is connected to the corresponding transmission device 300, and a stopper 600 is connected to one end of each mounting shaft 420 away from the corresponding transmission device 300. The stopper 600 is in limiting cooperation with the corresponding extrusion member 410 in the axial direction of the mounting shaft 420, and the mounting shafts 420 connected to the same transmission device 300 are connected to the same stopper 600.

[0049] In this embodiment, each extrusion member 410 can be rotatably sleeved on the corresponding installation shaft 420, so that when the extrusion member 410 extrudes the fluid delivery tube 510, the extrusion member 410 can roll relative to the fluid delivery tube 510, so that the friction between the extrusion member 410 and the fluid delivery tube 510 can be reduced, so that the service life of the extrusion member 410 and the fluid delivery tube 510 is long. In addition, by making the stopper 600 and the corresponding extrusion member 410 in the axial direction of the installation shaft 420, the extrusion member 410 can be prevented from being separated from the installation shaft 420 from the end of the installation shaft 420 away from the transmission device 300, so that the stability of the extrusion member 410 is better. Furthermore, by making each installation shaft 420 connected to the same transmission device 300 connected to the same stopper 600, the disassembly and assembly of all the stoppers 600 corresponding to the same transmission device 300 can be completed in one disassembly and assembly, which can save working procedures and make the use of the pumping system more convenient.

[0050] As a specific embodiment, when the transmission device 300 includes the planetary transmission mechanism described above, the mounting shaft 420 is, for example, arranged on the planetary carrier 310 of the planetary transmission mechanism and is parallel to the axis of the planetary carrier 310, so that the extrusion member 410 is eccentrically arranged on the transmission device 300, and the blocking member 600 is, for example, a plastic plate.

[0051] In other optional embodiments, the extrusion member 410 may also be fixed on the mounting shaft 420 , and in this case, the stopper 600 mentioned above may not be provided on the mounting shaft 420 .

[0052] In a further embodiment, any two adjacent transmission devices 300 may be transmission-connected via the stopper 600. In this way, the transmission connection between the two adjacent transmission devices 300 can be achieved without setting other additional structures, thereby making the overall structure of the pumping system simpler and making the cost of the pumping system lower.

[0053] As a specific implementation method, refer to Figure 9 As shown, in the case where the transmission device 300 includes the planetary transmission mechanism described above, the planet carrier 310 of one of the two adjacent transmission devices 300 close to the rotating drive member 200 is, for example, transmission connected to the sun gear 320 of the other one through a block 600, thereby realizing the transmission connection of the two adjacent transmission devices 300 through the block 600.

[0054] In other optional embodiments, any two adjacent transmission devices 300 may also be transmission-connected via a connecting structure, and the connecting structure and the stopper 600 mentioned above are two independent structures.

[0055] In a further embodiment, reference Figure 8As shown, the fluid delivery pipe 510 is in limit fit with the corresponding stopper 600 and the corresponding transmission device 300 in the axial direction of the mounting shaft 420. With such an arrangement, the fluid delivery pipe 510 is disposed between the stopper 600 and the transmission device 300, and both the stopper 600 and the transmission device 300 can limit the movement of the fluid delivery pipe 510 in the axial direction of the mounting shaft 420, thereby ensuring better stability of the fluid delivery pipe 510.

[0056] In other alternative embodiments, the fluid delivery pipe 510 may have no limit fit relationship with the corresponding stopper 600 and the corresponding transmission device 300 in the axial direction of the mounting shaft 420.

[0057] In a further embodiment, an extrusion member 410 may be eccentrically provided on each transmission device 300.

[0058] In other alternative embodiments, at least two extrusion members 410 may be eccentrically provided on each transmission device 300, and the extrusion members 410 are arranged at intervals along the circumferential direction of the transmission device 300. Compared with the solution of extruding the fluid delivery pipe 510 by one extrusion member 410 in the previous embodiment, in this embodiment, the number of extrusion members 410 for extruding the fluid delivery pipe 510 is larger, and each extrusion member 410 can drive the fluid to move along the extension direction of the fluid delivery pipe 510, thereby enabling a higher fluid delivery speed and thus a higher pumping efficiency of the pumping system.

[0059] During the specific use process, as the transmission device 300 rotates, each extrusion member 410 can extrude the corresponding fluid delivery pipe 510.

[0060] As a specific implementation manner, when the transmission device 300 includes the planetary transmission mechanism described above, the corresponding extrusion members 410 of the transmission device 300 are arranged at intervals along the circumferential direction of the planet carrier 310, for example.

[0061] In a further embodiment, referring to Figure 3 and Figure 8 As shown, the transmission devices 300 and the fluid delivery pipes 510 are arranged in sequence along the axial direction of the housing 100, and the transmission devices 300 and the fluid delivery pipes 510 are arranged alternately in the axial direction of the housing 100. The housing 100 includes at least two housings 110, and the housings 110 are arranged in sequence along the axial direction of the housing 100, and any two adjacent housings 110 can be detachably connected.

[0062] In this embodiment, both the arrangement of the transmission device 300 and the arrangement of the fluid delivery pipe 510 match the arrangement of the housing 110. In this way, when it is necessary to replace the transmission device 300 or the fluid delivery pipe 510, it is not necessary to remove the entire outer shell 100. Only the housing 110 corresponding to the part of the transmission device 300 or the fluid delivery pipe 510 needs to be removed, and then the replacement of the corresponding transmission device 300 or fluid delivery pipe 510 can be completed, thus making the replacement of both the transmission device 300 and the fluid delivery pipe 510 relatively convenient.

[0063] As a specific implementation manner, the housing 110 is, for example, a plastic housing.

[0064] In other alternative embodiments, the outer shell 100 can also be an integral structure.

[0065] In a further embodiment, refer to Figure 2 As shown, one of any two adjacent housings 110 is provided with a clamping portion 111, and the other is provided with a bayonet, and the clamping portion 111 is in clamping fit with the bayonet.

[0066] In this embodiment, by making the clamping portion 111 in clamping fit with the bayonet, the positions between two adjacent housings 110 can be pre-positioned, so that the connection between two adjacent housings 110 can be completed more conveniently and quickly.

[0067] In other alternative embodiments, the clamping portion 111 and the bayonet described above may not be provided.

[0068] In a further embodiment, refer to Figures 4 to 6 As shown, one side wall of one of any two adjacent housings 110 is provided with a first connection portion 112, and the other side wall is provided with a second connection portion 113. The first connection portion 112 is detachably connected to the second connection portion 113, and the fluid delivery pipes 510 correspond to the first connection portion 112 and the second connection portion 113 one by one. The inlet end and the outlet end of each fluid delivery pipe 510 are clamped between the corresponding first connection portion 112 and second connection portion 113. With such an arrangement, in addition to connecting two adjacent housings 110, the first connection portion 112 and the second connection portion 113 can also participate in fixing the fluid delivery pipes 510, so that there is no need to specifically provide other structures to fix the fluid delivery pipes 510, and thus the overall structure of the pumping system is relatively simple.

[0069] As a specific implementation manner, refer to Figure 10As shown, on one side of the first connecting portion 112 facing the second connecting portion 113, for example, a first card slot 1121 and a second card slot 1122 are provided. On one side of the second connecting portion 113 facing the first connecting portion 112, for example, a third card slot 1131 and a fourth card slot 1132 are provided. The inlet end of the fluid delivery pipe 510 is clamped in the first card slot 1121 and the third card slot 1131, and the outlet end of the fluid delivery pipe 510 is clamped in the second card slot 1122 and the fourth card slot 1132. Thus, both the inlet end and the outlet end of the fluid delivery pipe 510 are clamped between the corresponding first connecting portion 112 and the second connecting portion 113 of the fluid delivery pipe 510, and the first connecting portion 112 and the second connecting portion 113 are, for example, detachably connected by screws.

[0070] In other alternative embodiments, there may also be no corresponding relationship between the fluid delivery pipe 510 and the first connecting portion 112 and the second connecting portion 113.

[0071] In a further embodiment, the first connecting portions 112 may also be staggered from each other. With such an arrangement, it is possible to prevent the first connecting portions 112 from interfering with each other, thereby making the connection between each first connecting portion 112 and its corresponding second connecting portion 113 more convenient and rapid.

[0072] In other alternative embodiments, the first connecting portions 112 may also be arranged opposite to each other in a direction parallel to the axis of the housing 100.

[0073] In an alternative embodiment, referring to Figure 1 and Figure 2 as shown, a pipe joint 520 is provided at both the inlet end and the outlet end of each fluid delivery pipe 510. Due to the presence of the pipe joint 520, both the inlet end and the outlet end of the fluid delivery pipe 510 can be more conveniently and rapidly connected to other structures, thereby making the use of the pumping system more convenient.

[0074] In a further embodiment, referring to Figure 10 as shown, the ring gear 340 of each planetary transmission mechanism is an integral structure with the housing 100. With such an arrangement, the connection reliability between the ring gear 340 and the housing 100 is better, so that the ring gear 340 has a stronger ability to resist external force impacts.

[0075] In other alternative embodiments, the ring gear 340 and the housing 100 may also be two independent structures. In this case, the ring gear 340 and the housing 100 are, for example, connected by non-detachable means such as welding and gluing, or by detachable means such as screws and magnetic attraction.
