[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the scheme in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0045] In addition, the descriptions of "first", "second", etc. in the present utility model are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0046] In the cleaning system, the cleaning robot is usually equipped with a base station to perform daily care on the cleaning robot through the base station. The care types include various types, such as cleaning care. When the cleaning robot is placed on the base station, the base station can spray water on the cleaning robot to clean its cleaning parts (such as a mop).

[0047] Base stations usually use multi-way pipes to transport cleaning water. The multi-way pipes can divert the cleaning water. The cleaning water is diverted into multiple outlets to correspond to the multiple cleaning parts of the cleaning robot or to evenly supply water to various parts of a single cleaning part. During the cleaning process, according to the user's cleaning needs, cleaning liquid can be added to the water to form cleaning water to clean the cleaning parts of the cleaning robot. However, the tube body of the multi-way pipe is small in volume, the mixing space is small, and the internal water flow is laminar (the fluid particles move in an orderly manner and do not mix with each other, which is called laminar flow). As a result, after the cleaning liquid enters the multi-way pipe, it will flow along the water flow and along the tube wall, and the mixing with the water is uneven and insufficient, affecting the cleaning effect.

[0048] In the prior art, in order to solve the problem that the cleaning liquid flows along the water flow and the tube wall after entering the multi-way tube, and is not mixed evenly and fully with the water, a mixing chamber is set on the main pipe, and the liquid entering from the liquid inlet is mixed in the mixing chamber. However, the volume of the mixing chamber is large and the cost is high. When the multi-way tube in the prior art is set in the cleaning equipment, the cleaning equipment is large in volume and occupies a large space.

[0049] Based on the above-mentioned usage defects existing in the related prior art, the embodiment of the utility model proposes a multi-channel for liquid delivery, and can achieve uniform and sufficient mixing of water and liquid during the liquid delivery process. Figures 1 to 3 The multi-channel comprises: a multi-channel tube 100 and a liquid mixing structure 200. The multi-channel tube 100 comprises a main pipeline 110 and at least two branch pipelines 120. The main pipeline 110 is provided with a liquid inlet J and a diversion port F. The number of the liquid inlet J is at least two. One end of each branch pipeline 120 is connected to the diversion port F of the main pipeline 110, and the other end is provided with a liquid outlet J. The liquid mixing structure 200 is arranged on the multi-channel tube 100, and the liquid mixing structure 200 is used to mix the liquids entering the multi-channel tube 100 from the at least two liquid inlets J. The multiple liquid inlets J refer to liquid inlets J having a number of more than two, including liquid inlets J having a number of two. The liquid mixing structure comprises a diversion part, which is arranged in the main pipeline and located at the diversion port. The diversion part is used to collide with the liquid flow of the diversion port, so that the liquid flow flowing out of the diversion port is diverted into at least two streams and correspondingly introduced into at least two branch pipelines.

[0050] The main pipeline 110 is the main pipeline connecting the liquid inlet J and the branch pipeline 120, and the liquid entering the liquid inlet J will be mixed in the main pipeline 110. The diversion part can be plate-shaped, or it can be a scattered shape formed by connecting one end of multiple plates. If the diversion part is a scattered shape formed by connecting one end of multiple plates, the space between the two plates of the diversion part is connected to a branch pipeline 120. When the liquid flows along the main pipeline 110 to the diversion port, the liquid hits the diversion part, disrupting the liquid flow, and the liquids entering from multiple liquid inlets are mixed with each other, and the liquids are mixed evenly and fully. In addition, the diversion part diverts the liquid from the diversion port F to each branch pipeline 120. The diversion part is arranged on the multi-way pipe with a small volume, and can evenly mix the liquids entering from at least two liquid inlets J.

[0051] The cleaning equipment involved in this embodiment may be a base station, a cleaning robot, a floor scrubber, a commercial cleaning robot, etc., including but not limited to these. Multi-channels are applied to cleaning equipment to transport liquids on the cleaning equipment. Furthermore, there are many scenarios for multi-channel infusion, which are not limited in this embodiment. For example, if the cleaning equipment is a base station, for example, the multi-channel is used to transport cleaning liquid for cleaning the cleaning parts of the cleaning robot, or to transport cleaning liquid for cleaning the cleaning base station itself (such as the docking position of the cleaning robot); for example, if the cleaning equipment is a cleaning robot, for example, the multi-channel is used to transport mopping liquid for cleaning the ground.

[0052] During multi-channel infusion, liquid (such as water, additives, etc.) can enter the main channel 110 of the multi-channel tube 100 from at least two liquid inlets J, flow along the main channel 110 and flow out from the liquid outlet C.

[0053] The multi-channel pipe 100 includes branch pipes 120, the number of which is at least 2, and a branch port F is provided on the main pipe 110, one end of each branch pipe 120 is connected to the branch port F of the main pipe 110, and the other end is provided with a liquid outlet C. In the multi-channel, the flow direction of the liquid is: liquid inlet J→main pipe 110→dividing port F→branch pipe 120→liquid outlet C.

[0054] Among them, the main line 110 can be a straight pipe, and the length of the main line 110 is not limited here and can be set according to actual conditions. There are at least two liquid inlets J on the main line 110. Optionally, two, three or four liquid inlets J can be set according to actual conditions. At least two liquid inlets J can be respectively set at different positions of the main line 110, such as the end face, side face, etc. of the main line 110. At least two liquid inlets J can be used to allow different types of liquids to enter the main line 110, including water, cleaning liquid, curing liquid or other functional additives.

[0055] Furthermore, when the multi-channel is provided on the cleaning equipment, the liquid inlet J on the main line 110 can be connected to the liquid supply system of the cleaning equipment, and liquid is supplied to the liquid inlet J through the liquid supply system. For example, the liquid supply system may include a liquid storage chamber, a liquid supply pipeline and a liquid pump. The liquid storage chamber is connected to the liquid inlet J through the liquid supply pipeline. The liquid pump is provided in the liquid supply pipeline, and liquid can be pumped by the liquid pump to pump the liquid in the liquid storage chamber along the liquid supply pipeline to the liquid inlet J, and enter the multi-channel through the liquid inlet J. Exemplarily, at least two liquid inlets J can be connected to at least two liquid supply systems, and each liquid supply system supplies liquid to at least one liquid inlet J. Exemplarily, the liquid supply system may include a water supply system, a cleaning liquid supply system, a curing liquid supply system, or other functional liquid supply systems, etc., without limitation.

[0056] At least two branch pipelines 120 are provided. Optionally, two, three or four branch pipelines 120 may be provided, etc., according to actual conditions. The branch pipeline 120 may be a straight pipe, one end of each branch pipeline 120 is connected to the diversion port F of the main pipeline 110, and the other end is configured with a liquid outlet C. Therefore, when the liquid in the main pipeline 110 flows to the diversion port F, it flows into each branch pipeline 120 through the diversion port F, and finally flows out through the liquid outlet C. Exemplarily, at least two branch pipelines 120 are integrally formed with the main pipeline 110 or detachably connected. Among them, if Figure 1 and Figure 3 As shown, in the multi-way pipe 100, two branch pipes 120 are provided. Exemplarily, the two branch pipes 120 are perpendicular to the main pipe 110, and the cross-sectional shape of the multi-way pipe 100 is an inverted T shape. Among them, the pipe body material of the multi-way pipe 100 can be selected according to actual conditions, such as three types of polypropylene (PPR, polypropylene random), etc., and this embodiment does not limit this.

[0057] The liquid mixing structure 200 is arranged on the multi-way tube 100, and the function of the liquid mixing structure 200 is to mix the liquids entering from the multiple liquid inlets J with each other. The liquid mixing structure 200 can be in various forms. As an example, the liquid mixing structure 200 includes a miniature fan blade structure (not shown), which is rotatably arranged in the main pipe 110. When the liquid in the main pipe 110 flows, it continuously impacts the fan blade structure to make the fan blade structure rotate, thereby forming a stirring effect on the liquid in the main pipe 110, so that the liquids entering from the multiple liquid inlets J are mixed with each other. Furthermore, under the action of the liquid mixing structure 200, the liquids are mixed evenly and fully, which helps to improve the cleaning effect. In addition, the liquid mixing structure 200 can also adopt other forms, which are further described in subsequent embodiments.

[0058] In some embodiments, reference Figure 3The diversion port F is arranged at one end of the main line 110 , and the liquid inlet J includes: a first liquid inlet J1 and a second liquid inlet J2 , the first liquid inlet J1 is arranged at the other end of the main line 110 , and the second liquid inlet J2 is arranged between the first liquid inlet J1 and the diversion port F.

[0059] The first liquid inlet J1 and the second liquid inlet J2 can be used to input different types of liquids, for example, the first liquid inlet J1 is used to input water, and the second liquid inlet J2 is used to input cleaning liquid.

[0060] Taking this as an example, in the multi-channel liquid delivery process, when ordinary clean water is not required, water enters the main line 110 through the first liquid inlet J1, flows along the main line 110, is split from the branch port F into at least two branch lines 120, and then flows out from the liquid outlet C of each branch line 120. When ordinary clean water is required, water enters the main line 110 through the first liquid inlet J1, and at the same time, the cleaning liquid enters the main line 110 through the second liquid inlet J2. The cleaning liquid and water can be mixed while flowing along the main line 110 to be configured into ordinary clean water. The ordinary clean water is split from the branch port F into at least two branch lines 120, and then flows out from the liquid outlet C of each branch line 120.

[0061] In some embodiments, reference Figure 3 The multiple liquid inlets J also include: a third liquid inlet J3, and the third liquid inlet J3 is arranged between the second liquid inlet J2 and the diversion port F.

[0062] The first liquid inlet J1, the second liquid inlet J2 and the third liquid inlet J3 can be used to input different types of liquids, for example, the first liquid inlet J1 is used to input curing liquid, the second liquid inlet J2 is used to input cleaning liquid, and the third liquid inlet J3 is used to input water.

[0063] Taking this as an example, during the multi-channel liquid delivery process, when ordinary clean water needs to be configured, water enters the main line 110 through the third liquid inlet J3, and at the same time, the cleaning liquid enters the main line 110 through the second liquid inlet J2. The cleaning liquid and water can be mixed while flowing along the main line 110 to configure ordinary clean water. The ordinary clean water flows from the branch port F into at least two branch lines 120, and then flows out from the liquid outlet C of each branch line 120. Optionally, the water can be hot water, and the cleaning effect of the clean water configured by mixing hot water and cleaning liquid is better. Among them, taking the liquid flow direction of the main line 110 as the reference direction, the second liquid inlet J2 is in front and the third liquid inlet J3 is in the back. Therefore, when the cleaning liquid entering through the second liquid inlet J2 flows to the third liquid inlet J3, it will be dispersed by the water entering through the third liquid inlet J3, thereby evenly mixing with the water.

[0064] When it is necessary to configure cleaning and curing water, water enters the main line 110 through the third liquid inlet J3, and at the same time, the cleaning liquid enters the main line 110 through the second liquid inlet J2, and the curing liquid enters the main line 110 through the first liquid inlet J1. The curing liquid, the cleaning liquid and the water can be mixed when flowing along the main line 110 to configure the cleaning and curing water. The cleaning and curing water flows from the branch port F into at least two branch lines 120, and then flows out from the liquid outlet C of each branch line 120. Among them, along the liquid flow direction of the main line 110, the first liquid inlet J1, the second liquid inlet J2 and the third liquid inlet J3 are arranged in sequence, so when the curing liquid entering through the first liquid inlet J1 flows to the second liquid inlet J2, it will be dispersed by the cleaning liquid entering through the second liquid inlet J2, and thus uniformly mixed with the cleaning liquid. Also, when the mixed liquid formed by the curing liquid and the cleaning liquid flows to the third liquid inlet J3, it will be dispersed by the water entering through the third liquid inlet J3, and thus evenly mixed with the water. In actual application, according to the type of mixed liquid to be configured, the liquid inlets that are not used can be blocked accordingly. For example, when configuring ordinary cleaning water, block the first liquid inlet J1, input the cleaning liquid through the second liquid inlet J2, and input water through the third liquid inlet J3.

[0065] In some embodiments, reference Figure 3 The plurality of liquid inlets further include: a fourth liquid inlet J4, which is disposed between the second liquid inlet J2 and the third liquid inlet J3.

[0066] The first liquid inlet J1, the second liquid inlet J2, the third liquid inlet J3 and the fourth liquid inlet J4 can be used to input different types of liquids, respectively. For example, the first liquid inlet J1 is used to input curing liquid, the second liquid inlet J2 is used to input cleaning liquid, the third liquid inlet J3 is used to input water, and the fourth liquid inlet J4 is used to input electrolyzed water.

[0067] Taking this as an example, in the multi-channel liquid delivery process, when electrolyzed clean water needs to be configured, the electrolyzed water enters the main line 110 through the fourth liquid inlet J4, and at the same time, the cleaning liquid enters the main line 110 through the second liquid inlet J2. The cleaning liquid and the electrolyzed water can be mixed when flowing along the main line 110 to be configured as electrolyzed clean water. The electrolyzed clean water flows from the diversion port F into at least two branch lines 120, and then flows out from the liquid outlet C of each branch line 120. Among them, along the liquid flow direction of the main line 110, the second liquid inlet J2 and the fourth liquid inlet J4 are arranged in sequence. Therefore, when the cleaning liquid entering through the second liquid inlet J2 flows to the fourth liquid inlet J4, it will be dispersed by the electrolyzed water entering through the fourth liquid inlet J4, thereby evenly mixing with the electrolyzed water. In actual application, according to the type of mixed liquid to be configured, the liquid inlet that is not needed can be correspondingly blocked. For example, when configuring electrolytic cleaning water, the first liquid inlet J1 and the third liquid inlet J3 are blocked, the cleaning liquid is input through the second liquid inlet J2, and the electrolytic water is input through the fourth liquid inlet J4.

[0068] In some embodiments, reference Figure 3 , along the liquid flow direction of the main circuit 110, multiple liquid inlets J are staggered and distributed in sequence. Among them, the multiple liquid inlets J can be located on the same side or different sides of the main circuit 110. During the liquid transportation process, the liquids at the multiple liquid inlets J enter the main circuit 110 in sequence according to the arrangement order of the multiple liquid inlets J. Exemplarily, the multiple liquid inlets J can be arranged in sequence along the liquid flow direction of the main circuit 110 according to the type of liquid input. For example, along the liquid flow direction of the main circuit 110, the liquid inlet J for inputting the additive liquid is arranged in the front, and the liquid inlet J for inputting water is arranged in the back. Thereby, the additive liquid first enters the main circuit 110 from its liquid inlet J in the front, and when it flows through the liquid inlet J for inputting water, it will be impacted by the water entering later at the liquid inlet J, and then mixed with each other, which is beneficial to improve the mixing effect.

[0069] For example, along the liquid flow direction of the main line 110, the liquid inlet J disposed at the end of the main line 110 away from the diversion port F is used to input water, and the liquid inlet J disposed at the side of the main line 110 is used to input the additive liquid. The flow rate of water entering from the liquid inlet J at the end of the main line 110 away from the diversion port F is greater than the flow rate of the additive liquid input from the liquid inlet J at the side of the main line 110, and the water can impact the additive liquid, thereby mixing the water and the additive liquid.

[0070] In some embodiments, reference Figure 3 , the liquid mixing structure 200 includes a first constriction 210, and the first constriction 210 is constructed in the diversion port F. Specifically, the diversion port F has a portion with a reduced inner diameter to form the first constriction 210. Along the liquid flow direction of the main line 110, the inner diameter of the first constriction 210 is smaller than the inner diameter of other parts of the diversion port F, and smaller than the inner diameter of the main line 110, thereby forming a step on the inner wall of the diversion port F that can interfere with the flow of liquid. When the liquid in the main line 110 flows through the diversion port F, it passes through the first constriction 210 accordingly, and the flow is disturbed by the step at the first constriction 210. The first constriction 210 provided in this embodiment can disturb the liquid flow at the diversion port F, so that the water and liquid are mixed with each other, and the water and liquid are mixed evenly and fully.

[0071] In some embodiments, reference Figure 3, the liquid mixing structure 200 further includes a second constriction 220, and at least one of the liquid inlets J is configured with the second constriction 220. Among them, among the at least two liquid inlets J, one of the liquid inlets J may be configured with the second constriction 220, or multiple liquid inlets J may be configured with the second constriction 220. Specifically, when the second constriction 220 is configured in the liquid inlet J, the liquid inlet J has a portion with a reduced inner diameter to form the second constriction 220. With the liquid inlet direction as a reference direction, the inner diameter of the second constriction 220 is reduced relative to the inner diameter of other portions of the liquid inlet J. When the liquid flows through the liquid inlet J, it passes through the second constriction 220. Under the action of a certain liquid supply pressure, the hydraulic pressure will gradually increase due to the reduction in the inner diameter of the second constriction 220, thereby increasing the impact force of the liquid entering the main line 110 from the liquid inlet J, which can increase the impact effect on other liquids in the main line 110, and is conducive to uniform and sufficient mixing with other liquids in the main line 110.

[0072] In some embodiments, reference Figures 4 to 6 There are two branch pipelines 120, and the flow dividing part includes a flow dividing plate 230, which is arranged at the flow dividing port F. The flow dividing plate 230 is used to divide the liquid flow of the flow dividing port F into two streams and introduce them into the two branch pipelines 120 accordingly; two flow blocking parts 231 are protrudingly arranged on the flow dividing plate 230, and each flow blocking part 231 is connected to the inner wall of at least one branch pipeline 120 to separate the liquid inlets R at one end of the two branch pipelines 120 from each other and prevent the two branch pipelines 120 from communicating with each other.

[0073] Specifically, when the liquid flows along the main pipeline 110 to the diversion port F, the diverter plate 230 divides the liquid, and the liquid is diverted into two streams and introduced into the two branch pipelines 120 accordingly. In the process of diverting the liquid flow at the diversion port F, the diverter plate 230 also disturbs the liquid flow, so that the water and liquid are mixed with each other, and the water and liquid are mixed evenly and fully. In addition, under the diversion effect of the diverter plate 230, the amount of liquid entering each branch pipeline 120 from the main pipeline 110 is roughly the same, which is conducive to achieving uniform liquid discharge from the liquid outlet C of each branch pipeline 120.

[0074] The flow block 231 is provided on the flow divider 230, and the flow block 231 is connected to the inner wall of the branch pipe 120 to limit the flow path of the liquid flow after the flow is divided, so as to avoid the situation that the liquid flow is remixed and interferes with each other after the flow is divided. Figure 5 and Figure 6As shown, one end of the two branch pipelines 120 is respectively provided with a liquid inlet R, and both are connected to the diversion port F of the main pipeline 110. The opposite ends of the diversion plate 230 are respectively facing the liquid inlets R of the two branch pipelines 120, and the diversion plate 230 is provided with two baffles 231, which are respectively located at the opposite ends of the diversion plate 230 and protrude from the opposite sides of the diversion plate 230, one of the baffles 231 is connected to the inner wall of a corresponding branch pipeline 120, and the other baffle 231 is connected to the inner wall of the other corresponding branch pipeline 120. Under this structural configuration, the liquid inlets R at one end of the two branch pipelines 120 are separated from each other, and the two branch pipelines 120 are not connected to each other, so that the liquid flow will not be remixed after diversion, avoiding mutual interference.

[0075] In some embodiments, reference Figure 5 , the diverter plate 230 is located on the first plane;

[0076] At least one liquid inlet J is used for the addition of liquid, and its axis and the axis of the diversion port F are both located on a second plane, and the second plane coincides with the first plane.

[0077] Based on this structural construction and layout, after the additive liquid flows into the main pipeline 110 from the liquid inlet J for entry, even if it is not mixed with water and flows along one side of the inner wall of the main pipeline 110, when the additive liquid flows to the diverter plate 230, the diverter plate 230 will also divide the additive liquid and evenly guide it to each branch pipeline 120. The additive liquid is mixed with water in the branch pipeline 120, which is conducive to achieving uniform and sufficient mixing of water and liquid.

[0078] In some embodiments, reference Figures 7 to 9 , the axes of the liquid inlets R at one end of at least two branch pipelines 120 are located on the third plane together;

[0079] At least one liquid inlet is used for the addition of liquid, and its axis and the axis of the diversion port F are both on a fourth plane, and the fourth plane coincides with the third plane, so that the liquid flow in the main pipeline 110 is evenly divided into at least two streams when it flows to the diversion port F, and the at least two liquid flows flow into at least two branch pipelines 120 accordingly.

[0080] Based on this structural construction and layout, after the additive liquid flows into the main pipeline 110 from the liquid inlet, even if it is not mixed with water and flows along one side of the inner wall of the main pipeline 110, when the additive liquid flows out to the branch port F, it will automatically be diverted and evenly flow into each branch pipeline 120. The additive liquid is mixed with water in the branch pipeline 120, which is conducive to achieving uniform and sufficient mixing of the water and liquid.

[0081] The utility model also proposes a multi-channel, including a multi-channel tube and a liquid mixing structure, the multi-channel tube includes a main pipeline and at least two branch pipelines, the main pipeline is provided with a liquid inlet and a diversion port, the number of the liquid inlet is at least two, one end of each branch pipeline is connected to the diversion port of the main pipeline, and the other end is provided with a liquid outlet. The liquid mixing structure is arranged on the multi-channel tube, and the liquid mixing structure is used to mix the liquids entering the multi-channel tube from at least two liquid inlets. The liquid mixing structure includes a first constriction, and the first constriction is constructed in the diversion port; and / or the liquid mixing structure also includes a second constriction, and the second constriction is constructed in at least one liquid inlet.

[0082] Specifically, the diversion port F has a portion with a reduced inner diameter to form a first constriction 210. Along the liquid flow direction of the main passage 110, the inner diameter of the first constriction 210 is smaller than the inner diameter of other portions of the diversion port F, and smaller than the inner diameter of the main passage 110, thereby forming a step on the inner wall of the diversion port F that can interfere with the flow of liquid. When the liquid in the main passage 110 flows through the diversion port F, it passes through the first constriction 210 and is disturbed by the step at the first constriction 210. The first constriction 210 provided in this embodiment can disturb the liquid flow at the diversion port F, so that the water and liquid are mixed with each other, and the water and liquid are mixed evenly and fully.

[0083] One of the liquid inlets J may be configured with the second constriction 220, or multiple liquid inlets J may be configured with the second constriction 220. Specifically, when the second constriction 220 is configured in the liquid inlet J, there is a portion with a reduced inner diameter at the liquid inlet J to form the second constriction 220. Taking the liquid inlet direction as a reference direction, the inner diameter of the second constriction 220 is reduced relative to the inner diameter of other portions of the liquid inlet J. When the liquid flows through the liquid inlet J, it passes through the second constriction 220. Under the action of a certain liquid supply pressure, due to the reduction in the inner diameter of the second constriction 220, the hydraulic pressure will gradually increase, thereby increasing the impact force of the liquid entering the main line 110 from the liquid inlet J, which can increase the impact effect on other liquids in the main line 110, and is conducive to uniform and sufficient mixing with other liquids in the main line 110.
