[0056] In industrial production, scientific research, and civilian applications, pumps serve as crucial equipment for liquid transport, playing a vital role in moving liquids from one location to another. Whether it's the transfer of chemical raw materials, the addition of laboratory reagents, or the supply of water and cleaning solutions in cleaning equipment, the stable operation of pumps is indispensable.

[0057] Traditional pumps have difficulty controlling the delivery of various liquids, which limits their application.

[0058] Specifically, existing pump systems often have significant limitations when faced with the need to simultaneously deliver different volumes of liquid. Traditional pump systems have a single delivery pipeline, and the pump can only output one type of liquid. For example, in chemical mixing processes, it is necessary to simultaneously deliver and mix multiple liquids in different proportions, and conventional pumps cannot achieve precise volume ratios through a single extrusion. In cleaning scenarios, different cleaning solutions and clean water need to be output simultaneously for different levels of dirt and cleaning areas, and existing pumps also struggle to meet this requirement.

[0059] Therefore, providing a new type of pump body that can output different liquids in a single extrusion and adapt to complex liquid transportation needs has become an urgent problem to be solved in the industry.

[0060] Therefore, this application provides a pump body, which provides at least two delivery pipes 1110 inside the pump body to deliver different liquids, and drives the squeezing component to work so as to squeeze at least one of the multiple delivery pipes 1110. Thus, when the squeezing component is working, at least one liquid can be output in one squeezing action, thereby achieving the purpose of differentiated delivery control of different liquids.

[0061] For ease of explanation, the following embodiments use a pump body 1100 from one embodiment of this application applied to a cleaning system 1000. This cleaning system 1000 may include cleaning robots, such as sweeping robots, sweeping and mopping robots, floor scrubbers, etc., and may also include a cleaning robot base station 1300, or may include both a cleaning robot and a cleaning robot base station 1300. The cleaning robot base station 1300 is used for charging, water replenishment, cleaning fluid replenishment, cloth washing, dust collection, etc., of the cleaning robot.

[0062] Example 1

[0063] According to some embodiments of this application, refer to Figure 2-5 As shown, this application embodiment provides a pump body 1100, which includes at least two delivery pipes 1110, a squeezing assembly 1120, and a drive assembly 1130; wherein, each delivery pipe 1110 includes a liquid inlet 1111 and a liquid outlet 1112; at least two delivery pipes 1110 are at least partially sleeved on the squeezing assembly 1120; the drive assembly 1130 is connected to the squeezing assembly 1120 and drives the squeezing assembly 1120 to move, and the moving squeezing assembly 1120 squeezes at least one of the at least two delivery pipes 1110 to push the liquid in the delivery pipes 1110 toward the liquid outlet 1112.

[0064] For the delivery pipeline 1110, the delivery pipeline 1110 can extend along a preset path for a preset length. The two extended ends of the delivery pipeline 1110 can respectively form a liquid inlet 1111 and a liquid outlet 1112. A cavity can be formed inside the delivery pipeline 1110, and the liquid inlet 1111 and the liquid outlet 1112 are connected to the cavity. Liquid (or fluid) can flow inside the cavity. Different delivery pipelines 1110 can flow with different liquids. For example, the liquid may include water, cleaning fluid, etc.

[0065] There are at least two delivery pipelines 1110. These at least two delivery pipelines 1110 can be arranged vertically or side by side. In the following example, for the sake of convenience, we will take the example of two delivery pipelines 1110 installed in the pump body.

[0066] The extrusion assembly 1120 extrudes the delivery pipe 1110, causing the liquid in the delivery pipe 1110 to move from the liquid inlet 1111 to the liquid outlet 1112, and then be discharged from the liquid outlet 1112. In one possible implementation, the delivery pipe 1110 is made of an elastic material, such as rubber or silicone. This material gives the delivery pipe 1110 the ability to elastically deform in the radial direction, allowing it to undergo elastic deformation under the extrusion force of the extrusion assembly 1120, changing the internal flow area, and thus extruding the liquid from the liquid outlet 1112.

[0067] The elastic deformation of the conveying pipe 1110 in the radial direction can be understood as the pipe diameter of the conveying pipe 1110 undergoing elastic contraction and expansion deformation in the radial direction when subjected to radial extrusion force. It should be noted that a portion of the conveying pipe 1110 may also be capable of elastic deformation, for example, the portion of the conveying pipe 1110 that abuts against the extrusion assembly 1120 may be capable of elastic deformation.

[0068] In one interpretation, at least two delivery pipes 1110 are connected in parallel. Parallel connection can be understood as multiple delivery pipes 1110 being independent of each other and not connected. Each delivery pipe 1110 can independently deliver liquid. For example, each delivery pipe 1110 extends around a preset axis and forms a liquid inlet 1111 and a liquid outlet 1112 at two extension ends, respectively. The multiple delivery pipes 1110 are arranged at intervals along the preset axis, thereby forming two parallel delivery pipes 1110 inside the pump body 1100.

[0069] The extrusion assembly 1120 should be understood as a component capable of acting on the delivery pipe 1110, thereby extruding at least one of the at least two delivery pipes 1110. Through the extrusion force and the extrusion action, the cross-sectional area of ​​the delivery pipe 1110 changes, thus extruding the liquid inside the delivery pipe 1110 from the liquid outlet 1112. Based on the negative pressure inside the extruded delivery pipe 1110, the delivery pipe 1110 continues to draw liquid from the liquid inlet 1111. It can be understood that the extrusion assembly 1120 rotates under the drive of the drive assembly 1130, and during rotation, it extrudes the delivery pipe 1110 fitted thereon, causing the liquid in the delivery pipe 1110 to be extruded from the liquid inlet 1111 to the liquid outlet 1112.

[0070] When the extrusion assembly 1120 (such as the extrusion roller 1124 described below) extrudes the conveying pipe 1110, the internal space of the conveying pipe 1110 decreases due to elastic deformation, squeezing out the liquid inside; when the extrusion assembly 1120 (such as the extrusion roller 1124 described below) leaves, the conveying pipe 1110 returns to its original state, the internal pressure decreases, and the external liquid enters the conveying pipe 1110 under the action of the pressure difference.

[0071] Since the delivery pipes 1110 have a preset length, each delivery pipe 1110 can be at least partially fitted onto the extrusion assembly 1120. The delivery pipes 1110 are fixed or snapped onto the outer shell 1150 of the pump body 1100. The extrusion assembly 1120 can rotate or move linearly relative to the outer shell 1150, that is, the extrusion assembly 1120 can move relative to the delivery pipes 1110. For example, the entire or part of the extrusion assembly 1120 can move linearly or curvilinearly relative to the delivery pipes 1110 (e.g., the extrusion assembly 1120 rotates), thereby causing the extrusion assembly 1120 to extrude an extrusion action on the delivery pipes 1110. For example, the moving part of the extrusion assembly 1120 for extrusion intermittently abuts against the delivery pipes 1110. When abutting or connecting, the moving part generates extrusion force on the delivery pipes 1110.

[0072] It should be noted that when the extrusion assembly 1120 moves, a single extrusion action of the extrusion assembly 1120 can extrude at least one of the at least two delivery pipes 1110. Specifically, taking two delivery pipes 1110 as an example, in one case, the extrusion assembly 1120 can extrude each delivery pipe 1110 simultaneously in a single extrusion action; in another case, the extrusion assembly 1120 can extrude only one delivery pipe 1110 in a single extrusion action. This allows the extrusion assembly 1120 to selectively extrude different delivery pipes 1110, improving the flexibility of the pump's operation.

[0073] The drive assembly 1130 is a power-providing component that powers the movement of the extrusion assembly 1120, causing the extrusion assembly 1120 to move relative to the conveying pipeline 1110, thereby generating extrusion force on the conveying pipeline 1110. The power provided by the drive assembly 1130 can be continuous or intermittent, enabling the extrusion assembly 1120 to continuously or intermittently extrude force into the conveying pipeline 1110.

[0074] In this example, the pump body 1100 operates as follows: when the pump body 1100 is started, the drive source of the drive assembly 1130 starts working, thereby driving the extrusion assembly 1120 to work. The extrusion assembly 1120 moves relative to the delivery pipeline 1110 and generates extrusion force on at least one of the at least two delivery pipelines 1110, thereby extruding the liquid in the delivery pipeline 1110. Since at least two delivery pipelines 1110 are provided, the extrusion assembly 1120 enables at least two delivery pipelines 1110 to output at least two kinds of liquids during continuous operation, thereby achieving output control of multiple liquids.

[0075] In this embodiment, by providing at least two delivery pipes 1110 and enabling the extrusion assembly 1120 to extrude at least one of the two delivery pipes 1110, the extrusion assembly 1120 can achieve the purpose of delivering at least two liquids during continuous operation, thereby improving the application range of the pump body 1100 and enhancing the operational flexibility of the pump body 1100.

[0076] In some embodiments, refer to Figure 2 As shown, the cross-sectional area of ​​the lumens of the at least two delivery pipes 1110 is the same.

[0077] Specifically, the statement that at least two conveying pipes 1110 have the same cross-sectional area should be understood as meaning that the cross-sectional area of ​​the lumen of each of the multiple conveying pipes 1110 is equal. For example, if there are three conveying pipes 1110, the diameters of the lumens of the three conveying pipes 1110 are all equal.

[0078] In this embodiment, the cross-sectional area of ​​each delivery pipe 1110 is made equal, which makes it easy to achieve equal output of different liquids and facilitates precise control.

[0079] In some embodiments, refer to Figure 2 As shown, there are at least two delivery pipes 1110 with different cross-sectional areas.

[0080] Specifically, the situation where at least two conveying pipes 1110 have different cross-sectional areas includes two cases: one is that there are two conveying pipes 1110, and the cross-sectional areas of the two conveying pipes 1110 are not equal. Another case is that there are more than two conveying pipes 1110, for example, there are three conveying pipes 1110, and at least two of the three conveying pipes 1110 have unequal cross-sectional areas. This can also be understood as the three conveying pipes 1110 not being completely equal in cross-sectional areas; for example, the three conveying pipes 1110 have completely unequal cross-sectional areas, or two conveying pipes 1110 have equal cross-sectional areas, but the cross-sectional area of ​​the third conveying pipe 1110 is not equal to the cross-sectional areas of the two first conveying pipes 1110. It can be seen that when the number of conveying pipes 1110 is greater than three, the cross-sectional area of ​​the lumen of each conveying pipe 1110 may not be equal, or there may be a number of conveying pipes 1110 with equal lumen cross-sectional areas, but at least one conveying pipe 1110 has a lumen cross-sectional area that is not equal to the lumen cross-sectional areas of the rest of the conveying pipes 1110.

[0081] Taking two delivery pipelines 1110 as an example, in one feasible manner, the cross-sectional areas of the two delivery pipelines 1110 are different. For example, the outer contour of the cross-section of the pipeline is circular. Different cross-sectional areas mean that the diameters of the pipelines are not equal. If the diameter of one delivery pipeline 1110 is D1 and the diameter of the other delivery pipeline 1110 is D2, then D1 should not be equal to D2. For example, the diameters of different delivery pipelines 1110 can be set to 10mm, 15mm, etc. Through this differentiated diameter design, liquid delivery with different flow requirements can be met. One end of each delivery pipe 1110 serves as a liquid inlet 1111, connected to an external liquid source, and the other end serves as a liquid outlet 1112. It can be connected to different equipment or containers according to actual usage requirements. For example, the liquid outlet 1112 of one delivery pipe 1110 can be connected to the water outlet of a cleaning cloth, and the liquid outlet 1112 of another delivery pipe 1110 can be connected to the water supply nozzle of the cleaning system 1000.

[0082] In the following examples, for ease of description, we will use the example of a circular cross-sectional outline of the lumen.

[0083] For example, when the cross-sectional area of ​​the cavity of each delivery pipe 1110 is different, the extrusion of the extrusion component 1120 enables each delivery pipe 1110 to output different volumes of liquid, thereby achieving differentiated delivery and precise control of different liquids. By controlling the diameter ratio of each delivery pipe 1110, the purpose of precisely controlling the mixing ratio of multiple liquids can be achieved, thus broadening the application scenarios and usage flexibility of the pump body 1100.

[0084] In this embodiment, the cross-sectional area of ​​the cavity of at least a portion of the multiple conveying pipes 1110 is differentiated, so that liquids of different volumes can be squeezed out of each conveying pipe 1110, thereby realizing differentiated delivery of different liquids and achieving the effect of accurately controlling the output ratio of different liquids; differentiated delivery of liquids can be achieved by differentially controlling the diameter of the output pipes, which is ingenious in structure design and low in manufacturing cost.

[0085] In some embodiments, refer to Figure 2-5 As shown, the extrusion assembly 1120 includes at least two extrusion components 1123, which correspond to at least two conveying pipes 1110, and the conveying pipes 1110 are sleeved on the corresponding extrusion components 1123; the drive assembly 1130 is connected to the extrusion components 1123 to drive the extrusion components 1123 to move.

[0086] The structure in which at least two extrusion components 1123 correspond to at least two conveying pipes 1110 should be understood as follows: one extrusion component 1123 is connected to one conveying pipe 1110. In other words, one conveying pipe 1110 can be fitted onto one extrusion component 1123. The number of extrusion components 1123 corresponds one-to-one with the number of conveying pipes 1110.

[0087] Specifically, the squeezing member 1123 is connected to the delivery pipeline 1110 and squeezes the delivery pipeline 1110. The moving squeezing member 1123 squeezes at least one of the at least two delivery pipelines 1110 to push the liquid in the delivery pipeline 1110 toward the liquid outlet 1112.

[0088] There may be at least two extrusion components 1123, which can be understood as multiple components. Each extrusion component 1123 is matched with a corresponding conveying pipe 1110, so that one extrusion component 1123 exerts an extrusion force on one conveying pipe 1110. It should be further noted that multiple extrusion components 1123 can also be connected, or they can be directly manufactured using a one-piece molding method. That is, multiple extrusion components 1123 can also form an integrated extrusion structure module. In this example, the emphasis on multiple extrusion components 1123 is to illustrate the corresponding arrangement relationship between the extrusion components 1123 and the conveying pipes 1110.

[0089] In this embodiment, the extrusion component 1123 is matched with the delivery pipeline 1110, which helps to reduce the risk of mutual interference between the various delivery pipelines 1110 and provides a basis for each extrusion component 1123 to independently extrude and control the matched delivery pipeline 1110.

[0090] In some embodiments, refer to Figure 2-5 As shown, the drive assembly 1130 includes a power output shaft 1131, and the extrusion assembly 1120 also includes a mounting bracket 1121. The mounting bracket 1121 is connected to the power output shaft 1131 and can rotate under the drive of the power output shaft 1131. At least two extrusion components 1123 are connected to the mounting bracket 1121, and the at least two extrusion components 1123 rotate around the power output shaft 1131 with the mounting bracket 1121.

[0091] Specifically, the power output shaft 1131 is the power output component of the drive assembly 1130. Typically, the power output shaft 1131 outputs power in a rotational manner. For example, the drive assembly 1130 may be an electric motor, in which case the power output shaft 1131 is the output shaft of the electric motor.

[0092] Mounting bracket 1121 supports and bears the extrusion component 1123. Power output shaft 1131 is connected to mounting bracket 1121; therefore, power output shaft 1131 serves as the rotation center axis of the entire extrusion assembly 1120 (specifically, the extrusion component 1123). Drive assembly 1130 causes power output shaft 1131 to rotate around its own axis, thereby driving mounting bracket 1121 to rotate around the axis of power output shaft 1131. Each extrusion component 1123 is connected to mounting bracket 1121, and the extrusion component 1123 rotates with mounting bracket 1121, i.e., the extrusion... Component 1123 rotates around the axis of the power output shaft 1131. During the rotation of the squeezing component 1123, it comes into contact with the conveying pipe 1110, thereby squeezing out the liquid inside the cavity of the conveying pipe 1110. It is understood that the squeezing component 1123 needs to come into contact with the conveying pipe 1110 and move relative to it in order to squeeze out the liquid inside the conveying pipe 1110. Therefore, the connection between the squeezing component 1123 and the corresponding conveying pipe 1110 can be considered a movable connection. The conveying pipe 1110 is sleeved on the outer periphery of the squeezing component 1123 and the mounting bracket 1121.

[0093] In this embodiment, when the drive assembly 1130 drives the power output shaft 1131 to rotate, the mounting bracket 1121 rotates accordingly. The extrusion component 1123 contacts and extrudes the liquid into the delivery pipeline 1110, thereby achieving the purpose of extruding liquid into the multiple delivery pipelines 1110 in an orderly manner during the rotation of the multiple extrusion components 1123. In addition, the above structural design helps to improve the relative stability of the extrusion frequency and force on each delivery pipeline 1110, improves the stability and reliability of liquid delivery, and helps to reduce the flow fluctuation problem caused by uneven extrusion.

[0094] According to some embodiments of this application, refer to Figure 2-5 As shown, the at least two extrusion components 1123 are arranged axially along the power output shaft 1131 on the mounting bracket 1121.

[0095] Specifically, the at least two extrusion components 1123 are arranged axially along the power output shaft 1131 on the mounting bracket 1121. This should be understood as the multiple extrusion components 1123 in the extrusion assembly 1120 being arranged sequentially along the axial direction of the power output shaft 1131, with adjacent extrusion components 1123 being spaced apart.

[0096] Correspondingly, it can be seen that the at least two conveying pipes 1110 are also arranged in the axial direction along the power output shaft 1131, so that the extrusion member 1123 can correspond one-to-one with the conveying pipe 1110.

[0097] For example, if the extension path of the delivery pipe 1110 is arranged in a plane perpendicular to the power output shaft 1131, then multiple delivery pipes 1110 can be arranged at intervals along the axial direction of the power output shaft 1131. Correspondingly, multiple extrusion components 1123 will be arranged at intervals along the axial direction of the power output shaft 1131 on the mounting bracket 1121.

[0098] In this embodiment, the at least two extrusion components 1123 are arranged along the axial direction of the power output shaft 1131, which makes it easier for the power output shaft 1131 to simultaneously drive the at least two extrusion components 1123 to move through the mounting bracket 1121, making the structural layout more compact and saving the number of drive components 1130.

[0099] According to some embodiments of this application, refer to Figure 2 , Figure 3 and Figure 5 As shown, the mounting bracket 1121 includes a first disc 1125 disposed at both ends and at least one second disc 1126 disposed between the first disc 1125. The first disc 1125, the second disc 1126, and the second disc 1126 are connected by a connecting post 1127. The connecting post 1127 has a through hole 1128. The power output shaft 1131 is connected to the through hole 1128 and drives the mounting bracket 1121 to rotate.

[0100] Specifically, the first disc 1125 and the second disc 1126 can both be sheet-like structures. The two first discs 1125 located at both ends are arranged opposite each other, and at least one second disc 1126 is arranged between the two first discs 1125. The at least one second disc 1126 is arranged opposite to the first disc 1125 with a gap. For example, there is one second disc 1126 between the two first discs 1125. One first disc 1125 and the second disc 1126 are connected by a connecting post 1127, and the other first disc 1125 and the second disc 1126 are connected by another connecting post 1127. Of course, the two connecting posts 1127 can be an integral structure. For example, two second disks 1126 are provided between two first disks 1125. The two second disks 1126 are arranged opposite each other at intervals and are also opposite each other to the first disks 1125 at intervals. Each first disk 1125 is connected to the corresponding second disk 1126 through a connecting post 1127, and the two second disks 1126 are also connected to each other through a connecting post 1127.

[0101] The connecting post 1127 is a structure that connects to the power output shaft 1131. Therefore, the connecting post 1127 has a through hole 1128 in the direction along the axis. The power output shaft 1131 is inserted into the through hole 1128. In the circumferential direction, the power output shaft 1131 is limited in the through hole 1128, so that the power output shaft 1131 can drive the connecting post 1127 to rotate, that is, drive the mounting bracket 1121 to rotate.

[0102] In this embodiment, the mounting bracket 1121 adopts a structure in which the first plate 1125, the second plate 1126 and the connecting column 1127 are combined and connected, which is simple in structure and easy to manufacture.

[0103] According to some embodiments of this application, refer to Figure 2 and Figure 3 As shown, the extrusion component 1123 is connected between the first disc 1125 and the second disc 1126; or the extrusion component 1123 is connected between two second discs 1126 (not shown).

[0104] For example, a second disc 1126 is provided between two first discs 1125. One first disc 1125 and the second disc 1126 are connected by a connecting post 1127. Then, a pressing component 1123 is connected between the first disc 1125 and the second disc 1126. Another first disc 1125 and the second disc 1126 are connected by another connecting post 1127. Then, another pressing component 1123 is connected between the other first disc 1125 and the second disc 1126, thereby achieving the purpose of installing two pressing components 1123.

[0105] For example, refer to Figure 2 and Figure 3 As shown, two second discs 1126 are provided between two first discs 1125. The two second discs 1126 are arranged opposite each other at a distance and are also opposite to the first discs 1125 at a distance. Each first disc 1125 is connected to the corresponding second disc 1126 by a connecting post 1127. Each first disc 1125 and each second disc 1126 is provided with a pressing component 1123, thereby achieving the purpose of installing two pressing components 1123. The two second discs 1126 are also connected by a connecting post 1127, so a pressing component 1123 can also be installed between the two second discs 1126.

[0106] In this embodiment, by designing the structure of the mounting bracket 1121 differently, it is possible to connect multiple extrusion components 1123, making the structure of the extrusion assembly 1120 more compact.

[0107] The extrusion roller 1124 can be fixedly connected to the mounting frame 1121. When the extrusion roller 1124 comes into contact with and extrudes the conveying pipe 1110, sliding friction will occur between the extrusion roller 1124 and the conveying pipe 1110. The sliding friction causes significant wear to the conveying pipe 1110 and is quite harmful.

[0108] Therefore, according to some embodiments of this application, refer to Figure 5 As shown, the extrusion component 1123 includes at least one extrusion roller 1124, which is rotatably connected to the mounting frame 1121.

[0109] Specifically, the extrusion component 1123 includes at least one extrusion roller 1124, which is a component that extrudes and abuts against the conveying pipeline 1110. It is understood that the extrusion roller 1124 is mounted on the mounting bracket 1121 and spaced apart from the power output shaft 1131. For example, the central axis of the extrusion roller 1124 is spaced apart from and parallel to the axis (or central axis) of the power output shaft 1131. When multiple extrusion rollers 1124 are provided, they can be spaced apart and arranged around the power output shaft 1131. In the case of only one extrusion roller 1124, it can be considered a special case where the extrusion roller 1124 surrounds the power output shaft 1131. In this case, the extrusion roller 1124 can also be considered to be located on one side of the power output shaft 1131.

[0110] Each extrusion component 1123 includes at least one extrusion roller 1124 connected to the mounting bracket 1121 and arranged around the power output shaft 1131. The extrusion roller 1124 in each extrusion component 1123 intermittently abuts against the corresponding conveying pipe 1110. For example, the extrusion assembly 1120 includes two extrusion components 1123, wherein one extrusion component 1123 includes one extrusion roller 1124, and the other extrusion component 1123 includes multiple extrusion rollers 1124, which may be arranged at intervals.

[0111] Due to the spacing configuration of the extrusion rollers 1124, each extrusion roller 1124 in each extrusion component 1123 can contact and extrude with the corresponding conveying pipe 1110 at a set time interval, thereby enabling each extrusion roller 1124 in each extrusion component 1123 to form intermittent contact and extrusion with the corresponding conveying pipe 1110. The aforementioned intermittent feature can also be understood as a preset extrusion frequency.

[0112] In this embodiment, the intermittent contact of the extrusion roller 1124 enables intermittent liquid delivery. In scenarios requiring quantitative, intermittent liquid delivery, such as laboratory reagent addition, the amount of liquid extruded each time can be precisely controlled. Simultaneously, compared to continuous extrusion, intermittent extrusion reduces wear on the delivery pipeline 1110, extends its service life, and makes the pump body 1100 more energy-efficient during operation.

[0113] Specifically, for a pressing component 1123, for example, the pressing component 1123 includes two pressing rollers 1124 connected to the mounting bracket 1121, wherein one pressing roller 1124 is rotatable about the power output shaft 1131, or both pressing rollers 1124 are rotatable about the power output shaft 1131.

[0114] In some examples, the extrusion roller 1124 may be cylindrical and rotatably connected to the mounting frame 1121 about its own axis. The extrusion roller 1124 and the power output shaft 1131 are spaced apart and parallel to each other. The extrusion roller 1124 and the mounting frame 1121 may be connected by bearings to reduce friction and improve the smoothness of rotation.

[0115] When the pump body 1100 is working, the power output shaft 1131 causes the extrusion roller 1124 to rotate around the axis of the power output shaft 1131 through the mounting bracket 1121. When the extrusion roller 1124 comes into contact with the conveying pipe, friction is generated between the surface of the conveying pipe and the surface of the extrusion roller 1124. The friction causes the extrusion roller 1124 to rotate around its own axis. It can be seen that the extrusion roller 1124 also rotates during the process of extruding the conveying pipe 1110. That is to say, the extrusion roller 1124 rotates while extruding, thereby converting the sliding friction between the extrusion roller 1124 and the conveying pipe 1110 into rolling friction.

[0116] In this embodiment, by rotating the extrusion roller 1124 around its own axis, the friction between the extrusion roller 1124 and the conveying pipe 1110 is optimized into rolling friction, which reduces the friction and damage of the extrusion roller 1124 to the conveying pipe 1110, thus protecting the conveying pipe 1110. It also helps to reduce the frictional heat generated at the friction point and lower the temperature, which also forms a protection for the conveying pipe 1110.

[0117] According to some embodiments of this application, refer to Figure 5 As shown, the extrusion component 1123 includes at least one extrusion roller 1124, which is rotatably connected between the first disc 1125 and the second disc 1126.

[0118] Specifically, since a pressing component 1123 is provided between the first disc 1125 and the second disc 1126, and the pressing component 1123 is provided with at least one pressing roller 1124, it can be known that the pressing roller 1124 can be connected to the first disc 1125 and / or the second disc 1126. Considering the harmfulness of sliding friction between the pressing roller 1124 and the conveying pipe 1110, the pressing roller 1124 is rotatably connected to the first disc 1125 and / or the second disc 1126 around its own axis, thereby converting the sliding friction between the pressing roller 1124 and the conveying pipe 1110 into rolling friction.

[0119] In this embodiment, by rotating the extrusion roller 1124 around its own axis, the friction between the extrusion roller 1124 and the conveying pipe 1110 is optimized into rolling friction, which reduces the friction and damage of the extrusion roller 1124 to the conveying pipe 1110, thus protecting the conveying pipe 1110. It also helps to reduce the frictional heat generated at the friction point and lower the temperature, which also forms a protection for the conveying pipe 1110.

[0120] According to some embodiments of this application, refer to Figure 5 As shown, the extrusion component 1123 includes a plurality of extrusion rollers 1124, which are arranged at intervals around the circumference of the connecting column 1127.

[0121] Specifically, taking the example of multiple extrusion rollers 1124 in the extrusion component 1123, the multiple extrusion rollers 1124 are arranged around the connecting column 1127 (or power output shaft 1131) and spaced apart. The angle between the line connecting two adjacent extrusion rollers 1124 and the axis of the connecting column 1127 (or power output shaft 1131) can be adaptively designed according to the extrusion frequency and other requirements in various application scenarios. For example, if there are four extrusion rollers 1124, and the four extrusion rollers 1124 are evenly distributed in the circumferential direction of the connecting column 1127 (or power output shaft 1131), then the angle between the line connecting two adjacent extrusion rollers 1124 and the axis of the connecting column 1127 (or power output shaft 1131) is 90°.

[0122] In this embodiment, by providing multiple extrusion rollers 1124 in the extrusion component 1123, the extrusion frequency between the extrusion rollers 1124 and the conveying pipeline 1110 can be increased, thereby increasing the number of times liquid is output and improving work efficiency.

[0123] According to some embodiments of this application, refer to Figure 5 As shown, the number of extrusion rollers 1124 in each extrusion component 1123 is the same.

[0124] Specifically, multiple extrusion components 1123 can be provided, and the number of extrusion rollers 1124 in each extrusion component 1123 can be equal. For example, two extrusion components 1123 can be provided, and the two extrusion components 1123 are arranged at intervals in the vertical direction. Each of the upper and lower extrusion components 1123 is provided with three extrusion rollers 1124, and the three extrusion rollers 1124 are arranged at an angle of 120° on the circumference of the power output shaft 1131. By making the rotation period of the power output shaft 1131 consistent, it can be seen that when the power output shaft 1131 rotates once, the upper extrusion component 1123 can extrude the conveying pipe 1110 three times through the three extrusion rollers 1124, and the lower extrusion component 1123 can also extrude the conveying pipe 1110 three times through the three extrusion rollers 1124, thereby achieving the same extrusion frequency for the two conveying pipes 1110.

[0125] It should be further explained that although the number of extrusion rollers 1124 in each extrusion component 1123 is the same, so as to achieve the same extrusion frequency on the conveying pipeline 1110, the extrusion rollers 1124 in each extrusion component 1123 can be staggered in the vertical direction. That is to say, the central axes of the upper and lower extrusion rollers 1124 can not be collinear, so as to achieve the purpose of extruding different conveying pipelines 1110 at different times. This example enables multiple extrusion components 1123 to perform differentiated extrusion on the corresponding conveying pipelines 1110 at different times.

[0126] According to some embodiments of this application, the number of extrusion rollers 1124 in each extrusion component 1123 is different.

[0127] Specifically, multiple extrusion components 1123 may be provided, and the number of extrusion rollers 1124 in each extrusion component 1123 can be set according to specific needs. For example, three extrusion components 1123 may be provided, and the three extrusion components 1123 may be arranged at intervals in the vertical direction. The upper extrusion component 1123 may have two extrusion rollers 1124, which are arranged at an angle of 120° on the circumference of the power output shaft 1131. The lower extrusion component 1123 may have four extrusion rollers 1124, which are arranged at an angle of 90° on the circumference of the power output shaft 1131. By making the rotation cycle of the power output shaft 1131 consistent, it can be seen that when the power output shaft 1131 rotates once, the upper extrusion component 1123 can extrude the conveying pipe 1110 three times through the three extrusion rollers 1124, and the lower extrusion component 1123 can extrude the conveying pipe 1110 four times through the four extrusion rollers 1124, thereby realizing different extrusion frequencies for the two conveying pipes 1110.

[0128] According to some embodiments of this application, when each extrusion component 1123 includes a plurality of extrusion rollers 1124, the diameter of the extrusion rollers 1124 in each extrusion component 1123 is the same, or the diameter of the extrusion rollers 1124 in each extrusion component 1123 is not the same.

[0129] Specifically, the difference in diameter of the extrusion rollers 1124 directly affects the extrusion effect. In some applications, it is necessary to extrude the same volume of liquid in each extrusion action. Therefore, by making the diameters of each extrusion roller 1124 in each extrusion component 1123 equal, the contact area between each extrusion roller 1124 and the conveying pipe 1110 is equal, and the extrusion force generated during extrusion is also equal. This results in the same amount of deformation of the conveying pipe 1110, ensuring that the same volume of liquid is extruded in each extrusion. This is suitable for applications where the volume of liquid extruded in each extrusion requires high precision.

[0130] According to some embodiments of this application, the diameter of the extrusion roller 1124 in each extrusion component 1123 is not the same.

[0131] Specifically, the difference in the diameter of the extrusion roller 1124 directly affects the extrusion effect. A larger diameter extrusion roller 1124 has a larger contact area with the conveying pipe 1110, and generates a larger extrusion force during extrusion, which is suitable for scenarios that require rapid extrusion of large amounts of liquid; a smaller diameter extrusion roller 1124 has a relatively smaller contact area with the conveying pipe 1110, and generates a smaller extrusion force during extrusion, which is suitable for scenarios that require reducing the liquid output.

[0132] In this embodiment, by combining extrusion rollers 1124 of the same or different diameters, the extrusion method can be adjusted according to different liquid characteristics and flow requirements, so that the pump body 1100 can achieve efficient and accurate liquid delivery under various working conditions.

[0133] According to some embodiments of this application, refer to Figure 4 and Figure 9 As shown, the pump body 1100 also includes a housing 1150 having a accommodating cavity 1151, the housing 1150 having at least two connection inlets 1152 and at least two connection outlets 1153; the extrusion assembly 1120 and at least two delivery pipes 1110 are connected to the housing 1150 and located in the accommodating cavity 1151, the liquid inlet 1111 is correspondingly disposed at the connection inlet 1152, and the liquid outlet 1112 is correspondingly disposed at the connection inlet 1152.

[0134] Specifically, the outer shell 1150 may be made of a plate-like structure, and an accommodating cavity 1151 is formed inside the outer shell 1150. The accommodating cavity 1151 can be used to accommodate the conveying pipe 1110 and the extrusion assembly 1120. The extrusion assembly 1120 and at least two conveying pipes 1110 are connected to the outer shell 1150 and located within the accommodating cavity 1151. For example, the outer shell 1150 has a shell wall, which is an inner shell wall facing the accommodating cavity 1151. The surface of the pipe wall of the conveying pipe 1110 may abut or be spaced from the shell wall. When abutting, the pipe wall can provide counter-support to the conveying pipe 1110 when the extrusion roller 1124 extrudes the conveying pipe 1110.

[0135] Since the liquid inlet 1111 and liquid outlet 1112 of the delivery pipeline 1110 need to be connected to the outside, the housing 1150 needs to have connection inlets 1152 corresponding to the positions of the liquid inlets 1111 and connection outlets 1153 corresponding to the positions of the liquid outlets 1112. Therefore, it is understood that at least two connection inlets 1152 and at least two connection outlets 1153 are provided.

[0136] In this embodiment, the outer casing 1150 serves to house and protect the extrusion assembly 1120, the conveying pipeline 1110, and the like.

[0137] According to some embodiments of this application, refer to Figure 8 , Figure 9 and Figure 11 As shown, the pump body 1100 also includes at least two inlet connectors 1140 and at least two outlet connectors 1160. The inlet connectors 1140 are connected to the connection inlet 1152 of the housing 1150 and to the liquid inlet 1111 of the delivery pipeline 1110. The outlet connectors 1160 are connected to the connection outlet 1153 of the housing 1150 and to the liquid outlet 1112 of the delivery pipeline 1110.

[0138] Specifically, considering that in some cases the delivery pipeline 1110 is made of an elastic material, it is not easy to connect the liquid inlet 1111 and liquid outlet 1112 of the delivery pipeline 1110 to external pipelines. Therefore, in this example, an inlet connector 1140 is connected at the liquid inlet 1111. The inlet connector 1140 can be inserted into the liquid inlet 1111 of the delivery pipeline 1110 and can be inserted into the connection inlet 1152 of the housing 1150. An outlet connector 1160 is connected at the liquid outlet 1112. The outlet connector 1160 can be inserted into the liquid outlet 1112 of the delivery pipeline 1110 and can be inserted into the connection outlet 1153 of the housing 1150.

[0139] The outlet connector 1160 and the inlet connector 1140 can be made of metal or non-metal materials, which increases the rigidity of the outlet connector 1160 and the inlet connector 1140 and makes them less prone to deformation. One end of the outlet connector 1160 and the inlet connector 1140 can extend to the outside of the housing 1150, thereby facilitating connection with external piping structures.

[0140] In this embodiment, by providing an outlet connector 1160 and an inlet connector 1140, it is possible to facilitate the connection between the delivery pipeline 1110 and the external pipeline structure, thereby improving the convenience of installation and disassembly.

[0141] According to some embodiments of this application, refer to Figure 9 and Figure 11 As shown, the pump body 1100 also includes a positioning body 1170, at least two inlet connectors 1140 and at least two outlet connectors 1160 are connected to the positioning body 1170, and the positioning body 1170 is connected to the housing 1150.

[0142] Specifically, the positioning body 1170 is used to limit the inlet connector 1140 and the outlet connector 1160. During the preparation of the pump body 1100, the positioning body 1170 can be assembled with the inlet connector 1140 and the outlet connector 1160 to form an integrated structure, and then assembled with the outer shell 1150. The positioning body 1170 can form an assembly module with the inlet connector 1140, the outlet connector 1160 and the conveying pipeline 1110, so that the positioning body 1170 can play a supporting role for the conveying pipeline 1110, which facilitates the installation and positioning of the conveying pipeline 1110 and the outer shell 1150.

[0143] The positioning body 1170 can be a plate structure. The inlet connector 1140 and the outlet connector 1160 can be inserted into the insertion through holes provided on the positioning body 1170, and the inlet connector 1140 and the outlet connector 1160 can be interference-fitted with the insertion through holes. The positioning body 1170 can be located in the accommodating cavity 1151. The plate surface of the plate structure can be opposite to or attached to the shell wall of the outer shell 1150. The positioning body 1170 can be limited and connected to the shell wall of the outer shell 1150. For example, a limiting groove is formed on the shell wall of the outer shell 1150, and the positioning body 1170 is inserted and limited within the limiting groove.

[0144] In this embodiment, the positioning body 1170 plays a role in positioning and supporting the inlet connector 1140 and the outlet connector 1160, which facilitates the assembly and positioning of the delivery pipeline 1110 and the housing 1150, and improves the ease of assembly between the inlet connector 1140, the outlet connector 1160 and the delivery pipeline 1110 and the housing 1150.

[0145] According to some embodiments of this application, refer to Figure 11 As shown, the positioning body 1170 includes at least four sub-positioning bodies 1171, at least two inlet connectors 1140 and at least two outlet connectors 1160 are correspondingly connected to the at least four sub-positioning bodies 1171.

[0146] Specifically, since there are at least two delivery pipes 1110, there are correspondingly at least two inlet connectors 1140 and at least two outlet connectors 1160. Both inlet connectors 1140 and outlet connectors 1160 need to be connected to the positioning body 1170. Therefore, in order to make the inlet connectors 1140 and outlet connectors 1160 more independent of each other and reduce interference, the positioning body 1170 is designed to include at least four sub-positioning bodies 1171, so that each inlet connector 1140 and each outlet connector 1160 is connected to a sub-positioning body 1171.

[0147] The sub-positioning body 1171 can adopt a plate structure. The inlet connector 1140 and the outlet connector 1160 can be respectively inserted into the insertion through holes provided on the sub-positioning body 1171. The inlet connector 1140 and the outlet connector 1160 can be interference-fitted with the insertion through holes.

[0148] The sub-positioning body 1171 is located inside the accommodating cavity 1151. The plate surface of the sub-positioning body 1171 can be disposed opposite to or attached to the shell wall of the outer shell 1150. The sub-positioning body 1171 can be limited and connected to the shell wall of the outer shell 1150. For example, a limiting groove is formed on the shell wall of the outer shell 1150, and the sub-positioning body 1171 is inserted and limited in the limiting groove.

[0149] In this embodiment, the positioning body 1170 adopts a split structure. The sub-positioning body 1171 independently fixes and limits each inlet connector 1140 and outlet connector 1160, making the connection between the inlet connector 1140, outlet connector 1160 and the outer shell 1150 more flexible.

[0150] Example 2

[0151] Unlike Example 1, referring to Figure 6-8 and Figure 10 As shown, in this embodiment, the drive assembly 1130 includes a first output shaft 1136, and the pump body 1100 includes a speed regulating assembly 1132 and a second output shaft 1137. The second output shaft 1137 is connected to the first output shaft 1136 through the speed regulating assembly 1132. At least one of the at least two extrusion components 1123 is connected to the first output shaft 1136, and the other extrusion components 1123 are connected to the second output shaft 1137. The rotational speed of the first output shaft 1136 is different from that of the second output shaft 1137.

[0152] Specifically, the first output shaft 1136 is connected to the speed regulating component 1132, which in turn is connected to the second output shaft 1137. Therefore, the speed regulating component 1132 serves to adjust the rotational speeds of the first and second output shafts 1136 and 1137, resulting in different rotational speeds for each shaft. Furthermore, since the first output shaft 1136 connects to at least one of the at least two extrusion components 1123, and the second output shaft 1137 connects to the remaining extrusion components 1123, it can be understood that the first and second output shafts 1136 and 1137 can drive different extrusion components 1123 to rotate differently, thereby adjusting the extrusion frequency of the extrusion components 1123.

[0153] In this embodiment, by setting the speed regulating component 1132, a second output shaft 1137 with a transfer speed different from that of the first output shaft 1136 is formed, thereby making the different extrusion components 1123 extrude different frequencies on the delivery pipeline 1110, and the different delivery pipelines 1110 can intermittently deliver liquids of different volumes.

[0154] According to some embodiments of this application, refer to Figure 6-8 and Figure 10 As shown, the extrusion assembly 1120 further includes at least two sub-mounting brackets 1122, and at least two extrusion components 1123 are correspondingly connected to the at least two sub-mounting brackets 1122; one of the at least two sub-mounting brackets 1122 is connected to the first output shaft 1136, and the remaining sub-mounting brackets 1122 are correspondingly connected to the second output shaft 1137; the at least two extrusion components 1123 are correspondingly connected to the at least two sub-mounting brackets 1122.

[0155] Specifically, the extrusion assembly 1120 includes at least two sub-mounting brackets 1122, the number of which matches the number of extrusion components 1123, such that one extrusion component 1123 is mounted on one sub-mounting bracket 1122, and the at least two sub-mounting brackets 1122 are arranged axially spaced along the first output shaft 1136. The extrusion rollers 1124 in the extrusion components 1123 are mounted on the sub-mounting brackets 1122.

[0156] The first output shaft 1136 is the motion shaft of the drive assembly 1130 for outputting power. The first drive shaft is connected to one of the sub-mounting brackets 1122, thereby driving the sub-mounting bracket 1122 to rotate around the first output shaft 1136. Multiple extrusion rollers 1124 are spaced around the outer periphery of the first output shaft 1136. The rotation of the sub-mounting bracket 1122 drives the extrusion rollers 1124 to rotate around the first output shaft 1136, thereby causing the multiple extrusion rollers 1124 to sequentially extrude the conveying pipe 1110.

[0157] The first output shaft 1136 is connected to the speed regulating component 1132 for transmission. The second output shaft 1137 is the output shaft of the speed regulating component 1132 for power output. At least one second output shaft 1137 is provided, and this at least one second output shaft 1137 is used to connect one-to-one with the remaining sub-mounting brackets 1122 among the at least two sub-mounting brackets 1122. That is, one second output shaft 1137 is connected to one sub-mounting bracket 1122, thereby allowing the remaining sub-mounting brackets 1122 to rotate around the second output shaft 1137. The remaining sub-mounting brackets 1122 are also correspondingly equipped with pressing components 1123. The pressing component 1123 may include at least one pressing roller 1124, which is mounted on the sub-mounting bracket 1122.

[0158] The speed regulating component 1132 is used to regulate the rotational speed. After the speed of the first output shaft 1136 is regulated by the regulating component, the power is output by the second output shaft 1137, so that the rotational speed of the second output shaft 1137 is different from that of the first output shaft 1136, thereby achieving the purpose of making the rotational speed of the sub-mounting bracket 1122 connected to the first output shaft 1136 different from that of the sub-mounting bracket 1122 connected to the second output shaft 1137.

[0159] The speed control assembly 1132 has a power output end, each of which is connected to a second output shaft 1137, enabling the remaining sub-mounting brackets 1122 to rotate at a different speed than the sub-mounting brackets 1122 connected to the first output shaft 1136. By making the speeds of the first output shaft 1136 and the second output shaft 1137 different, the rotation cycle of the sub-mounting brackets 1122 and the extrusion frequency of the extrusion component 1123 on the conveying pipeline 1110 are adjusted.

[0160] Taking the extrusion assembly 1120, which includes two sub-mounting brackets 1122, as an example, the first output shaft 1136 is connected to the speed regulating assembly 1132 for transmission. The power output end of the speed regulating assembly 1132 is connected to a second output shaft 1137. The first output shaft 1136 is connected to one sub-mounting bracket 1122, and the second output shaft 1137 is connected to the other sub-mounting bracket 1122. The two sub-mounting brackets 1122 are arranged at intervals along the axial direction of the first output shaft 1136. Both sub-mounting brackets 1122 are connected to extrusion components 1123 (specifically extrusion rollers 1124). The first output shaft 1136 and the second output shaft 1137 rotate at different speeds, which in turn causes the two sub-mounting brackets 1122 to rotate at different speeds. Consequently, the two extrusion components 1123 make contact with the corresponding conveying pipes 1110 at different times, which means the extrusion frequency is different. This results in different numbers of times the liquid is output from the liquid outlet 1112 of the conveying pipe 1110, and consequently, the volumes of the two liquids output from the two conveying pipes 1110 are different, thus achieving the purpose of differentiated liquid output.

[0161] In this embodiment, the corresponding extrusion component 1123, sub-mounting bracket 1122 and first output shaft 1136 are modularly and independently configured, and the corresponding extrusion component 1123, sub-mounting bracket 1122 and second output shaft 1137 are modularly and independently configured. The speed is adjusted by the speed regulating component 1132, so that the rotation speed of the multiple sub-mounting brackets 1122 is different, thereby enabling different extrusion components 1123 to perform differentiated extrusion on different delivery pipelines 1110, thereby improving the pump body 1100's ability to output liquids in a differentiated manner.

[0162] According to some embodiments of this application, refer to Figure 6-8 and Figure 10As shown, the first output shaft 1136 and the second output shaft 1137 are arranged axially at intervals.

[0163] Specifically, the first output shaft 1136 and the second output shaft 1137 extend in the same direction, so that their central axes are parallel. The first output shaft 1136 and the second output shaft 1137 are spaced apart along their axial direction. In a direction perpendicular to the first output shaft 1136 or the second output shaft 1137, the first output shaft 1136 and the second output shaft 1137 can be arranged opposite to or offset from each other; that is, their central axes are collinear or offset from each other.

[0164] In this embodiment, the first output shaft 1136 and the second output shaft 1137 are arranged at intervals along the axial direction of the first output shaft 1136 or the second output shaft 1137. That is, the at least two pressing components 1123 are arranged along the axial direction of the power output shaft 1131, which facilitates the simultaneous driving of the at least two pressing components 1123 by the power output shaft 1131 via the mounting bracket 1121. This results in a more compact structural layout and reduces the number of drive assemblies 1130 required. According to some embodiments of this application, see... Figure 6-8 and Figure 10 As shown, the sub-mounting bracket 1122 includes a first disc 1125 and a second disc 1126 respectively disposed at both ends. A pressing component 1123 is connected between the first disc 1125 and the second disc 1126. The first disc 1125 and the second disc 1126 are connected by a connecting post 1127. A through hole 1128 is provided on the connecting post 1127. A first output shaft 1136 is connected to the corresponding through hole 1128, and a second output shaft 1137 is connected to the corresponding through hole 1128, so as to drive at least two sub-mounting brackets 1122 to rotate.

[0165] Specifically, the first disc 1125 and the second disc 1126 can both be sheet-like structures. The first disc 1125 and the second disc 1126 are arranged opposite to each other. The first disc 1125 is connected to the second disc 1126 through a connecting post 1127 to form a sub-mounting bracket 1122. A pressing component 1123 is connected between the first disc 1125 and the second disc 1126.

[0166] The connecting post 1127 is a structure that connects to the first output shaft 1136 and the second output shaft 1137. Therefore, the connecting post 1127 has a through hole 1128 along the axial direction. The first output shaft 1136 is inserted into the through hole 1128 of the connecting post 1127 of one sub-mounting bracket 1122, and the second output shaft 1137 is inserted into the through hole 1128 of the connecting post 1127 of another sub-mounting bracket 1122. In the circumferential direction, the first output shaft 1136 and the second output shaft 1137 are both limited in the through hole 1128, so that the first output shaft 1136 and the second output shaft 1137 can drive the connecting post 1127 to rotate, that is, drive the corresponding sub-mounting bracket 1122 to rotate.

[0167] In this embodiment, the sub-mounting bracket 1122 adopts a structure in which the first plate 1125, the second plate 1126 and the connecting column 1127 are combined and connected, which is simple in structure and easy to manufacture.

[0168] According to some embodiments of this application, refer to Figure 6-8 and Figure 10 As shown, the speed regulating component 1132 includes an input gear 1135 and an output gear 1134. A first output shaft 1136 is connected to the input gear 1135, and the output gear 1134 is correspondingly connected to the second output shaft 1137. Both the input gear 1135 and the output gear 1134 are part of the gear transmission mechanism 1133.

[0169] Considering the higher transmission accuracy of the gear transmission mechanism 1133, the speed regulating component 1132 uses gear meshing to transmit motion. The purpose of the speed regulating component 1132 is to adjust the rotation of each second output shaft 1137 to be different from that of the first output shaft 1136. Therefore, the speed regulating component 1132 should include multiple sets of transmission parts that cooperate with each other for output and input.

[0170] Specifically, the speed regulating component 1132 may include a gear transmission mechanism 1133, which includes an input gear 1135 and an output gear 1134. The number of output gears 1134 should be equal to the number of second output shafts 1137, so that one output gear 1134 is connected to one second output shaft 1137. It is understood that the gear transmission mechanism 1133 is composed of a complex gear train transmission structure, which may also include other meshing gear structures. The output gear 1134 is located at the output end of the motion.

[0171] In some examples, the gear transmission mechanism 1133 may also have multiple output ends, that is, multiple second output shafts 1137 may also be provided, and correspondingly, multiple output gears 1134 may be provided. Each output gear 1134 and its corresponding input gear 1135 have a preset transmission ratio. The transmission ratios of different output gears 1134 and input gears 1135 can be designed differently so that each second output shaft 1137 can have different rotational speeds. The first output shaft 1136 and the second output shaft 1137 have different rotational speeds. The different rotational speeds of each second output shaft 1137 enable the rotational cycles of each extrusion component 1123 to be different, thereby enabling the extrusion frequencies of each extrusion component 1123 and its corresponding conveying pipeline 1110 to be different, thus achieving the purpose of each conveying pipeline 1110 outputting liquid at different frequencies.

[0172] When the pump body 1100 in this example is working, the drive component works, causing the gear transmission mechanism 1133 to start running. The gear train in it starts to rotate, and the motion is transmitted to the output gear 1134 through the input gear 1135. The output gear 1134 rotates around its own axis, and drives the corresponding sub-mounting bracket 1122 to rotate through the second output shaft 1137. This further drives the corresponding extrusion component 1123 (specifically the extrusion roller 1124 described below) to rotate around the second output shaft 1137. Each extrusion component 1123 can independently extrude each delivery pipeline 1110.

[0173] In this embodiment, the gear transmission mechanism 1133 has advantages such as accurate transmission ratio, high transmission efficiency, and reliable operation. Through gear transmission, the power of the drive component 1130 can be stably transmitted to the first output shaft 1136 and the second output shaft 1137, and precise speed regulation can be achieved. In addition, by differentiating the transmission ratio between each output gear 1134 and the corresponding input gear 1135, the purpose of outputting liquid at different frequencies can be achieved in each delivery pipeline 1110.

[0174] According to some embodiments of this application, refer to Figure 6-8 As shown, the extrusion component 1123 includes at least one extrusion roller 1124, which is rotatably connected to the sub-mount 1122.

[0175] Specifically, each extrusion component 1123 includes at least one extrusion roller 1124, which is mounted on a sub-mounting bracket 1122. Taking two extrusion components 1123 as an example, one is a first extrusion unit, where the extrusion roller 1124 is the first extrusion roller 1124; the other is a second extrusion component 1123, where the extrusion roller 1124 is the second extrusion roller 1124. The first extrusion roller 1124 is connected to one sub-mounting bracket 1122 and arranged at a distance from the first output shaft 1136. The second extrusion roller 1124 is connected to another sub-mounting bracket 1122 and arranged at a distance from the second output shaft 1137. When multiple first extrusion rollers 1124 are provided, they are arranged around the first output shaft 1136. When multiple second extrusion rollers 1124 are provided, they are arranged around the second output shaft 1137.

[0176] In this embodiment, the intermittent contact of the extrusion roller 1124 enables intermittent liquid delivery. In scenarios requiring quantitative, intermittent liquid delivery, such as laboratory reagent addition, the amount of liquid extruded each time can be precisely controlled. Simultaneously, compared to continuous extrusion, intermittent extrusion reduces wear on the delivery pipeline 1110, extends its service life, and makes the pump body 1100 more energy-efficient during operation.

[0177] According to some embodiments of this application, refer to Figure 6-8 As shown, at least one extrusion roller 1124 is rotatably connected to the sub-mount frame 1122, that is, at least one extrusion roller 1124 is rotatably mounted on the sub-mount frame 1122 about the first output shaft 1136, and at least one extrusion roller 1124 is rotatably mounted on the sub-mount frame 1122 about the second output shaft 1137.

[0178] Specifically, each of the two sub-mounting frames 1122 may be connected to at least one extrusion roller 1124, and the extrusion roller 1124 is rotatably connected to the sub-mounting frame 1122, so that the extrusion roller 1124 can be rotatably connected to the sub-mounting frame 1122 around its own axis.

[0179] In some examples, the extrusion roller 1124 may be cylindrical and rotatably connected to the sub-mounting bracket 1122 about its own axis. The central axis of the extrusion roller 1124 connected to one sub-mounting bracket 1122 is spaced apart from and parallel to the central axis of the first output shaft 1136, and the central axis of the extrusion roller 1124 connected to another sub-mounting bracket 1122 is spaced apart from and parallel to the central axis of the second output shaft 1137. The extrusion roller 1124 and the sub-mounting bracket 1122 may be connected by bearings to reduce friction and improve the smoothness of rotation.

[0180] In this embodiment, by rotating the extrusion roller 1124 around its own axis, the friction between the extrusion roller 1124 and the conveying pipe 1110 is optimized into rolling friction, which reduces the friction and damage of the extrusion roller 1124 to the conveying pipe 1110, thus protecting the conveying pipe 1110. It also helps to reduce the frictional heat generated at the friction point and lower the temperature, which also forms a protection for the conveying pipe 1110.

[0181] According to some embodiments of this application, refer to Figure 6-8 As shown, the extrusion component 1123 includes at least one extrusion roller 1124, which is rotatably connected between the first disc 1125 and the second disc 1126.

[0182] Specifically, since a pressing component 1123 is provided between the first disc 1125 and the second disc 1126, and the pressing component 1123 is provided with at least one pressing roller 1124, it can be known that the pressing roller 1124 can be connected to the first disc 1125 and / or the second disc 1126. Considering the harmfulness of sliding friction between the pressing roller 1124 and the conveying pipe 1110, the pressing roller 1124 is rotatably connected to the first disc 1125 and / or the second disc 1126 around its own axis, thereby converting the sliding friction between the pressing roller 1124 and the conveying pipe 1110 into rolling friction.

[0183] In this embodiment, by rotating the extrusion roller 1124 around its own axis, the friction between the extrusion roller 1124 and the conveying pipe 1110 is optimized into rolling friction, which reduces the friction and damage of the extrusion roller 1124 to the conveying pipe 1110, thus protecting the conveying pipe 1110. It also helps to reduce the frictional heat generated at the friction point and lower the temperature, which also forms a protection for the conveying pipe 1110.

[0184] According to some embodiments of this application, refer to Figure 6-8 As shown, the extrusion component 1123 includes a plurality of extrusion rollers 1124, which are arranged at intervals around the circumference of the connecting column 1127.

[0185] Specifically, taking the example of multiple extrusion rollers 1124 in the extrusion component 1123, the multiple extrusion rollers 1124 are arranged around the connecting column 1127 (or the first output shaft 1136 or the second output shaft 1137) and spaced apart. The included angle between the line connecting two adjacent extrusion rollers 1124 and the axis of the corresponding connecting column 1127 can be adaptively designed according to the extrusion frequency and other requirements in various application scenarios. For example, if there are four extrusion rollers 1124, and the four extrusion rollers 1124 are evenly distributed in the circumference of the corresponding connecting column 1127, then the included angle between the line connecting two adjacent extrusion rollers 1124 and the axis of the connecting column 1127 is 90°.

[0186] In this embodiment, by providing multiple extrusion rollers 1124 in the extrusion component 1123, the extrusion frequency between the extrusion rollers 1124 and the conveying pipeline 1110 can be increased, thereby increasing the number of times liquid is output and improving work efficiency.

[0187] According to some embodiments of this application, refer to Figure 1 As shown, this application also provides a base station 1300 for a cleaning system. The base station 1300 for the cleaning system includes at least two housings 1200 and a pump body 1100 as described in the above embodiments. The housings 1200 have receiving cavities, and the liquid inlets 1111 of at least two delivery pipelines 1110 are connected to the receiving cavities of the at least two housings 1200.

[0188] Base station 1300 is an auxiliary device that provides liquid supply and other support to cleaning system 1000. It stores various liquids required for cleaning (such as water and cleaning agents) in its own housing 1200, and delivers the liquids to the cleaning execution components in cleaning system 1000 as needed via pump 1100 and delivery pipeline 1110, ensuring that cleaning system 1000 can continuously and efficiently perform cleaning operations. Simply put, base station 1300 is like a "supply station" and "power transmission station" for cleaning system 1000, providing the necessary material and power support for the normal operation of cleaning system 1000, and is an indispensable and important component of cleaning system 1000.

[0189] Specifically, each tank 1200 has an independent receiving cavity, which is the core part of the tank 1200 and its main function is to store various liquids required for cleaning. For example, the receiving cavity of one tank 1200 can be used to store clean water, providing a basic cleaning water source for the cleaning system 1000; the receiving cavity of another tank 1200 can store cleaning agents to enhance the cleaning effect. Of course, depending on the actual cleaning needs, the receiving cavity can also store other types of liquids, such as disinfectants. The material of the tank 1200 can be selected according to the characteristics of the stored liquid, generally using corrosion-resistant and high-strength materials to ensure the service life of the tank 1200. At the same time, the structural design of the tank 1200 should facilitate the injection and removal of liquids, and some tanks 1200 can also be equipped with a liquid level observation window to allow users to easily check the remaining liquid level. The pump 1100 in this embodiment adopts the structure of the above embodiment, and it is a key component for realizing liquid transportation. The pump body 1100 has at least two delivery pipes 1110, each with a liquid inlet 1111. Powered by its own motor, the pump body 1100 draws liquid from the containment chamber of the housing 1200 through the liquid inlet 1111 and delivers it to the corresponding part of the cleaning system 1000 via the delivery pipes 1110, providing power support for cleaning operations. The power source for the pump body 1100 can be electricity, etc., and its operating efficiency and stability directly affect the liquid delivery effect and the working performance of the cleaning system 1000. Furthermore, the pump body 1100 can adjust its flow rate according to actual needs to adapt to the liquid volume requirements of different cleaning scenarios. At least two delivery pipes 1110 have liquid inlets 1111 corresponding to the receiving cavities of at least two tanks 1200. This corresponding connection ensures that the liquid in each tank 1200 can be delivered by the pump body 1100 through an independent delivery pipe 1110, reducing the risk of mixing of different liquids during delivery and ensuring the purity of the liquid and the stability of the cleaning effect. For example, a tank 1200 storing clean water is connected to one liquid inlet 1111 of the pump body 110 through one delivery pipe 1110, and a tank 1200 storing cleaning agent is connected to another liquid inlet 1111 of the pump body 110 through another delivery pipe 1110. The pump body 1100 can deliver clean water and cleaning agent to the working area of ​​the cleaning system 1000 separately or simultaneously.

[0190] Because it has at least two tanks 1200 that can store different types of liquids, the cleaning system 1000 can choose to use a single liquid or a combination of liquids depending on the cleaning task, greatly expanding the applicability of the cleaning system 1000. For example, for routine light cleaning, only water can be used; while for dealing with more stubborn stains, water and detergent can be mixed.

[0191] Each housing 1200 is connected to the pump body 1100 via a corresponding delivery pipeline 1110. The pump body 1100 can flexibly control the delivery of liquid as needed, eliminating the need for frequent manual replacement or addition of liquid, reducing manual operation steps and improving the efficiency of cleaning work. At the same time, the liquid level observation window allows users to replenish liquid in a timely manner, avoiding disruption to cleaning work due to insufficient liquid.

[0192] The structural design of the pump body 1100 ensures the stability and reliability of liquid delivery, enabling it to deliver liquid to the designated location according to the set flow rate and pressure, ensuring uniformity of cleaning effect. Furthermore, the independent delivery pipeline 1110 reduces the risk of mutual interference and contamination between different liquids, ensuring the stability of liquid properties.

[0193] The housing 1200 is made of high-quality materials such as corrosion-resistant materials. The reasonable design and operation of the pump body 1100 reduces the corrosion and wear of the equipment components by the liquid, extends the service life of the cleaning system base station 1300 and the entire cleaning system 1000, and reduces the maintenance cost of the equipment.

[0194] The example of the cleaning system base station 1300 in this application is based on the example of the pump body 1100 described above. The example of the cleaning system base station 1300 includes all the technical effects of the example of the pump body 1100 described above, and will not be repeated here.

[0195] According to some embodiments of this application, refer to Figure 1 As shown, this application also provides a cleaning system 1000, which includes a cleaning robot. The cleaning robot includes the aforementioned pump body 1100 and at least two tanks 1200, specifically a first tank and a second tank. The first tank is a clean water tank, and the second tank is a cleaning liquid tank. The liquid inlets 1111 of at least two delivery pipes 1110 in the pump body are correspondingly connected to the at least two tanks. Through the aforementioned pump body, liquid can be simultaneously drawn into at least two tanks. The clean water drawn from the first tank is delivered to the wet cleaning component of the cleaning robot through the corresponding delivery pipe, and the cleaning liquid drawn from the second tank is delivered to the wet cleaning component of the cleaning robot through the corresponding delivery pipe, so as to achieve efficient liquid delivery. Correspondingly, the inner diameter of the delivery pipe 1110 corresponding to the cleaning liquid tank, or at least the inner diameter of the pipe fitted on the extrusion assembly of the pump body, is smaller than the delivery pipe corresponding to the clean water tank, or the rotation speed of the extrusion assembly corresponding to the cleaning liquid tank is smaller than the rotation speed of the extrusion assembly corresponding to the clean water tank, so as to achieve an effective ratio of clean water and cleaning liquid.

[0196] In some embodiments, the pump body 1100 described above is provided in both the cleaning robot of the cleaning system 1000 and the base station.

[0197] The pump body 1100 in this embodiment is applied to the cleaning system 1000. Leveraging its advantages of flexible flow adjustment and adaptability to various liquids, it allows for precise control of the cleaning fluid delivery volume according to different cleaning task requirements. For large-area cleaning, it can simultaneously deliver larger flow rates of different cleaning fluids, improving cleaning efficiency; in fine cleaning operations, it delivers cleaning fluid with a smaller and more precise flow rate to ensure cleaning effectiveness. Furthermore, because the pump body 1100 can adapt to the characteristics of different cleaning fluids, the cleaning system 1000 is suitable for cleaning objects of different materials and varying degrees of soiling, greatly enhancing the versatility and practicality of the cleaning system 1000 and meeting diverse cleaning needs.

[0198] The example of the cleaning system 1000 in this application is based on the example of the pump body 1100 described above. The example of the cleaning system 1000 includes all the technical effects of the example of the pump body 1100 described above, and will not be repeated here.

These descriptions are only for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application, as well as other specific embodiments of this application that can be conceived by those skilled in the art without creative effort, should be included within the scope of protection of this application.
